Patent Description:
With the advancement of science and technology, electronic devices such as a mobile phone play an important role in people's production and life. A user who is under fatigue or tension may play some games on the mobile phone to relieve the fatigue or tension. To reduce difficulty of operation, the electronic devices such as a mobile phone may usually be equipped with a handle, so that the user manipulates a persona or performs a corresponding operation through the handle. A key in the handle that is currently available usually needs to be disposed in a tilting state to facilitate pressing by the user. In a handle that has been mounted, a key corresponding to the index finger of a left hand, for example, usually faces the upper left, and a key corresponding to the index finger of a right hand usually faces the upper right. However, due to different hand sizes between users, the status of the finger in fit with the key varies between different users. Therefore, different users have sharply different experience on the same handle. The universal applicability of the handle is relatively low.

This application discloses an electronic device and a handle thereof, and can solve a current problem that different users have sharply different experience on the same handle and that the universal applicability of the handle is relatively low.

To solve the above technical problem, an embodiment of this application is implemented in the following way:.

According to a first aspect, an embodiment of this application discloses a handle, including:.

A plurality of snap slots are disposed on one of an inner wall of the inner cavity or a sidewall of the key assembly, and the sidewall faces the inner wall. The plurality of snap slots are distributed along a rotation direction of the key assembly. At least one snap buckle is disposed on the other of the inner wall of the inner cavity or the sidewall of the key assembly. The snap buckle and the snap slot are in limiting fit with each other in the rotation direction of the key assembly.

In a case that the snap buckle is in a first position, the resetting piece is in a first state, the snap slot disengages from the snap buckle, and the key assembly is rotatable relative to the main body.

In a case that the snap buckle is in a second position, the resetting piece is in a second state, the snap slot engages with the snap buckle, and the key assembly is fixed relative to the main body.

According to a second aspect, an embodiment of this application discloses an electronic device, including a device body and the handle.

The handle disclosed in an embodiment of this application includes a main body, a key assembly, and a resetting piece. The key assembly is rotatable relative to the main body, so that the orientation of the key assembly in the handle can be changed. In this way, a user can adjust the orientation of the key assembly based on specific status of the finger that fits with the key assembly, and the finger fits with the key assembly more effectively. For example, the finger fits with the key assembly more closely, or a pressing direction of the finger is caused to be a pressure-bearing direction of the key assembly, and the like. In this way, different users have the same or similar experience on the handle when using the handle, thereby enhancing the universal applicability of the handle. In addition, in the handle, the key assembly and the main body limit positions mutually through the snap buckle and the snap slot. In this way, after being adjusted, the key assembly is no longer rotatable relative to main body. Therefore, the orientation of the key assembly remains unchanged in subsequent operations, thereby providing the user with consistent experience. Moreover, by enabling the key assembly to be movable relative to the main body along a direction perpendicular to the relative rotation direction, the handle is ensured to be still capable of adjusting the orientation of the key assembly in the case that the snap buckle and the snap slot are disposed. In addition, the resetting piece prevents relative movement of the key assembly relative to the main body in unexpected circumstances. When the user adjusts the orientation of the key assembly, the resetting piece facilitates the snap buckle to engage in the snap slot, thereby reducing difficulty of adjustment and further enhancing user experience.

The drawings described herein are intended to enable a further understanding of this application, and constitute a part of this application. The exemplary embodiments of this application and the description thereof are intended to explain this application but not to constitute any undue limitation on this application. In the drawings:.

To make the objectives, technical solutions, and advantages of the present invention clearer, the following describes the technical solutions of the present invention clearly and thoroughly with reference to specific embodiments of the present invention and the corresponding drawings. Evidently, the described embodiments are merely a part of but not all of the embodiments of the present invention. All other embodiments derived by a person of ordinary skill in the art based on the embodiments of the present invention without making any creative effort fall within the protection scope of the present invention.

With reference to drawings, the following describes in detail the technical solution disclosed in each embodiment of this application.

As shown in <FIG>, this application discloses a handle. The handle includes a main body <NUM>, a key assembly, and a resetting piece. The handle is connectible to a device body. In addition, the handle may further include a claw <NUM>. The main body <NUM> is fixedly connected to the claw <NUM>. By virtue of the claw <NUM>, the entire handle can be detachably mounted on the device body, thereby facilitating operations of a user. After completion of the operations, the handle may be removed, so that the device body is still portable.

The main body <NUM> is a main part of the handle, and may be used as a mounting foundation of the key assembly and the resetting piece. The main body <NUM> may be made of hard materials such as metal or plastic. Alternatively, the main body <NUM> may be formed of a plastic material that is of good hand feeling and some flexibility, so as to prevent the handle from excoriating the user during operations and enhance the user experience of the handle. The shape and size of the main body <NUM> may be selected based on actual conditions, without being limited herein. Optionally, a surface of the main body <NUM> is of a profiling grip structure. In this case, the comfort of the grip of the entire handle is further improved, and the handle is more ergonomic. A specific structure of the surface of the main body <NUM> may be flexibly determined based on parameters such as the overall shape and dimensions of the main body <NUM>.

The key assembly is an operable part on the handle. The user may operate the key assembly by pressing, rubbing, rotating, or the like to generate corresponding operation content. The key assembly includes a key <NUM>, and will be described in detail below. The key assembly is rotatably mounted on the main body <NUM>. Specifically, the key assembly may be mounted on the main body <NUM> by using a structural member such as a pin shaft. By disposing a limiting structure or the like at an end of the pin shaft away from the main body <NUM>, the key assembly can be prevented from being detached from the main body <NUM>, and the key assembly is ensured to be rotatable relative to the main body <NUM> around the pin shaft. Moreover, the key assembly can move relative to the main body <NUM> along a direction perpendicular to the rotation direction of the key assembly. Specifically, by enlarging the size of a through-hole in fit with the pin shaft on the key assembly, the pin shaft can move in the through-hole, so that the key assembly can move relative to the main body <NUM> along the direction perpendicular to the rotation direction of the key assembly.

In another embodiment of this application, the main body <NUM> includes an inner cavity. The main body <NUM> includes an opening communicated with the inner cavity. In this case, the key assembly can be combined with the main body <NUM> by being mounted in the inner cavity, and can be prevented from being detached accidentally. By making the main body <NUM> include at least two detachable parts, the at least two parts can be fixedly connected to each other, and it is also ensured that the key assembly can be mounted into the inner cavity of the main body <NUM>. In the case that the above embodiment is adopted, the key assembly can be rotated in the inner cavity, and the key assembly can move relative to the main body <NUM> along an axial direction of the opening of the main body <NUM>.

Based on the above embodiment, in order to facilitate the user to operate the key assembly, optionally, a part of the key assembly protrudes from the opening. In other words, a part of the key assembly is located in the inner cavity of the main body <NUM> to prevent the key assembly from being detached from the main body <NUM>, and another part of the key assembly is caused to protrude out of the inner cavity through the opening.

In the above structure of the main body <NUM> and the key assembly, the key assembly is rotatable relative to the main body <NUM>. Therefore, during operations of the handle disclosed in this application, the user can rotate the key assembly to make the orientation of the key assembly adapt to the same finger of different users (such as index fingers of different users) and different fingers (such as index finger and middle finger) of the same user. By adjusting the orientation of the key assembly, the handle can also be caused to adapt to the corresponding fingers of the user's left or right hand.

In addition, after the user completes the process of adjusting the orientation of the key assembly, the orientation of the key assembly needs to be made to no longer change, so as to ensure that the user enjoys good experience all along. In the handle, a plurality of snap slots <NUM> are disposed on one of an inner wall of the inner cavity of the main body <NUM> or a sidewall of the key assembly, and the sidewall faces the inner wall. At least one snap buckle <NUM> is disposed on the other of the inner wall of the inner cavity or the sidewall of the key assembly. The plurality of snap buckles <NUM> are distributed along the rotation direction of the key assembly. By means of a mutual fit between the snap buckles <NUM> and the snap slots <NUM>, the key assembly and the main body <NUM> can limit positions of each other in the rotation direction of the key assembly to maintain a state of relative fixing between the key assembly and the main body <NUM>.

In addition, as mentioned above, the key assembly is movable relative to the main body <NUM> along the direction perpendicular to the rotation direction of the key assembly (such as an axial direction of the opening). Therefore, obviously, during the relative movement between the key assembly and the main body, depending on the movement direction, two circumstances may occur: the snap buckle <NUM> is disengaged from the snap slot <NUM>, or the snap buckle <NUM> extends into the snap slot <NUM>.

Therefore, when the user needs to adjust the orientation of the key assembly, the user may cause the key assembly to move relative to the main body <NUM> first, so as to disengage the snap buckle <NUM> from the snap slot <NUM>. Subsequently, by causing the key assembly to rotate relative to the main body <NUM>, the user causes the key assembly to move in an opposite direction of the main body <NUM> after the key assembly rotates to a desired position, and causes the snap buckle <NUM> to extend into and engage in the snap slot <NUM> to complete the adjustment of the key assembly.

Further, in order to prevent unexpected movement of the key assembly relative to the main body <NUM>, both the key assembly and the main body <NUM> are connected to the resetting piece. The resetting piece may exert a force on the key assembly and the main body <NUM> so that the key assembly is closer to the main body. That is, the snap buckle <NUM> engages in the snap slot <NUM>, or in other words, the snap buckle <NUM> is restricted from coming out of the snap slot <NUM>.

Based on the above embodiment, the handle disclosed in this application is in at least two states. In a case that the snap buckle <NUM> is in a first position, the resetting piece is in a first state, the snap slot <NUM> disengages from the snap buckle <NUM>, and the key assembly is rotatable relative to the main body <NUM>. In a case that the snap buckle <NUM> is in a second position, the resetting piece is in a second state, the snap slot <NUM> engages with the snap buckle <NUM>, and the key assembly is fixedly connected to the main body <NUM>, so that the key assembly is not rotatable relative to the main body <NUM>. Definitely, when the key assembly is subjected to collision or another external force, the key assembly can still move relative to the main body <NUM>. This circumstance also falls within the protection scope of the above embodiment.

Optionally, the resetting piece is specifically an elastomer such as a spring. Two opposite ends of the resetting piece are connected to the key assembly and the main body <NUM> respectively. When the snap buckle <NUM> engages in the snap slot <NUM>, the resetting piece is caused to be in a natural state. In another embodiment of this application, when the snap buckle <NUM> engages in the snap slot <NUM>, the resetting piece is caused to be in an extended state to achieve a more stable relationship of the limiting fit between the snap buckle <NUM> and the snap slot <NUM>. In each embodiment described above, when the snap buckle <NUM> disengages from the snap slot <NUM>, the resetting piece is elongated to exert a resetting force on the key assembly and the main body <NUM>.

The handle disclosed in an embodiment of this application includes a main body <NUM>, a key assembly, and a resetting piece. The key assembly is rotatable relative to the main body <NUM>, so that the orientation of the key assembly in the handle can be changed. In this way, a user can adjust the orientation of the key assembly based on specific status of the finger that fits with the key assembly, and the finger fits with the key assembly more effectively. For example, the finger fits with the key assembly more closely, or a pressing direction of the finger is caused to be a pressure-bearing direction of the key assembly, and the like. In this way, different users have the same or similar experience on the handle when using the handle, thereby enhancing the universal applicability of the handle. In addition, in the handle, the key assembly and the main body <NUM> limit positions mutually through the snap buckle <NUM> and the snap slot <NUM>. In this way, after being adjusted, the key assembly is no longer rotatable relative to main body <NUM>. Therefore, the orientation of the key assembly remains unchanged in subsequent operations, thereby providing the user with consistent experience. Moreover, by enabling the key assembly to be movable relative to the main body <NUM> along a direction perpendicular to the relative rotation direction, the handle is ensured to be still capable of adjusting the orientation of the key assembly in the case that the snap buckle <NUM> and the snap slot <NUM> are disposed. In addition, the resetting piece prevents relative movement of the key assembly relative to the main body <NUM> in unexpected circumstances. When the user adjusts the orientation of the key assembly, the resetting piece facilitates the snap buckle <NUM> to engage in the snap slot <NUM>, thereby reducing difficulty of adjustment and further enhancing user experience.

As mentioned above, the resetting piece may be an elastomer. In another embodiment of this application, as shown in <FIG> and <FIG>, the resetting piece may include a first magnetic assembly <NUM> and a second magnetic assembly <NUM>. The first magnetic assembly <NUM> and the second magnetic assembly <NUM> are disposed in a magnetic absorption manner. Of the first magnetic assembly <NUM> or the second magnetic assembly <NUM>, one is disposed in the inner cavity of the main body <NUM>, and the other is disposed in the key assembly. By disposing the first magnetic assembly <NUM> opposite to the second magnetic assembly <NUM>, the first magnetic assembly <NUM> and the second magnetic assembly <NUM> can cause the key assembly and the main body <NUM> to move closer to each other when the key assembly and the main body <NUM> move away from each other along the direction perpendicular to the rotation direction.

Specifically, at least one of the first magnetic assembly <NUM> or the second magnetic assembly <NUM> is a magnet such as a permanent magnet or an electromagnet. In a case that just one of the first magnetic assembly or the second magnetic assembly is a magnet, the other of the first magnetic assembly or the second magnetic assembly needs to be a structure made of a material that can be adsorbed by a magnet, such as iron, cobalt, or nickel. In a case that both the first magnetic assembly <NUM> and the second magnetic assembly <NUM> are magnets, magnetic poles at opposite ends of the first magnetic assembly and the second magnetic assembly need to be different, so as to ensure an ability of mutual adsorption between the first magnetic assembly and the second magnetic assembly.

Further, one of the first magnetic assembly <NUM> or the second magnetic assembly <NUM> is an arcuate structural member, and is caused to extend along the rotation direction of the key assembly. In this case, a good adsorption effect is ensured between the first magnetic assembly <NUM> and the second magnetic assembly <NUM> no matter how the key assembly rotates relative to the main body <NUM>.

Specifically, a coverage angle of the arcuate structural member may be determined based on a maximum relative rotation angle between the key assembly and the main body <NUM>, and the coverage angle of the arcuate structural member may be caused to be slightly larger than a maximum relative rotation angle between the key assembly and the main body <NUM>, so as to further ensure a consistently good adsorption effect between the first magnetic assembly <NUM> and the second magnetic assembly <NUM>. It is hereby noted that the rotation direction of the key assembly is the relative rotation direction between the key assembly and the main body <NUM>.

As mentioned above, a plurality of snap slots <NUM> are disposed on one of the inner wall of the inner cavity of the main body <NUM> or the sidewall of the key assembly, where the sidewall faces the inner wall. Compared with the key assembly, the main body <NUM> is larger in size. Therefore, when the number of snap slots <NUM> disposed on the main body <NUM> is identical to the number of snap slots disposed on the key assembly, a snap slot <NUM> on the main body is larger in size than that on the key assembly. Similarly, when the size of the snap slots <NUM> disposed on the main body <NUM> is identical to the size of the snap slots disposed on the key assembly, the number of snap slots <NUM> that can be disposed on the main body <NUM> is larger than the number of snap slots that can be disposed on the key assembly. Therefore, optionally, the snap slot <NUM> is disposed on the main body <NUM>, and the snap buckle <NUM> is disposed on the key assembly.

In addition, the snap buckle <NUM> may be centrally disposed on the key assembly. In this case, when the user presses the key assembly, an interaction force exerted on the key assembly substantially acts on the main body <NUM> through the snap buckle <NUM>, thereby facilitating engagement of the snap buckle <NUM> in the snap slot <NUM> and preventing the snap buckle <NUM> from coming out of the snap slot <NUM> under the pressing force of the user because the snap buckle <NUM> is located on a side on which the pressing force is exerted.

Based on the above embodiment, further, the main body <NUM> is divided into a first part and a second part by a first plane. At least one of the plurality of snap slots <NUM> is located in the first part, and at least one of the plurality of snap slots <NUM> is located in the second part. The first plane passes through a rotation axis of the key assembly and an axis of the opening of the main body <NUM>. That is, a straight line collinear with the rotation axis of the key assembly and a straight line collinear with the axial direction of the opening of the main body <NUM> are located in the first plane.

In an example in which the first part of the main body <NUM> is a left half of the main body <NUM> and the second part of the main body is a right half of the main body <NUM>, by adopting the above technical solution, it is ensured that at least one snap slot <NUM> is disposed on both the left half and the right half of the main body <NUM>. In this way, in a case that the main body fits with the key assembly, the snap buckle <NUM> is caused to fit with the snap slot <NUM> on the left half of the main body <NUM>, and the key assembly is caused to face the right side of the main body <NUM>, thereby facilitating the user to manipulate the handle with the left hand. Alternately, the snap buckle <NUM> is caused to fit with the snap slot <NUM> on the right half of the main body <NUM>, and the key assembly is caused to face the left side of the main body <NUM>, thereby facilitating the user to manipulate the handle with the right hand.

It is hereby noted that, in the above technical solution, a core purpose is to enable the user to manipulate the handle with the left hand or the right hand by disposing the snap slot <NUM> on both the left half and the right half of the main body <NUM>. When the specific structure and mounting manner of the handle have changed, the above technical solution can be adopted adaptively to achieve the above purpose. For example, when the snap buckle <NUM> is not centrally disposed on the key assembly, all the snap slots <NUM> may be caused to be located on the left half (or right half) of the main body <NUM>. The snap slot <NUM> in fit with the snap buckle <NUM> may be adjusted to also achieve the purpose of enabling the user to manipulate the handle with the left hand and manipulate the handle with the right hand.

As mentioned above, in the case that the key assembly is mounted in the inner cavity of the main body <NUM>, the main body <NUM> may be caused to include at least two detachable parts. Similar to the above embodiment, the main body <NUM> may include a left half and a right half that are detachably connected to each other. The left half is structurally symmetrical to the right half, and may be spliced to the right half to form the inner cavity and the opening.

In another embodiment of this application, the main body <NUM> may include an accommodation portion <NUM> and a stopper <NUM>. The accommodation portion <NUM> communicates with the inner cavity. Optionally, both the inner cavity and the opening are disposed on the accommodation portion <NUM>. An access hole may be further disposed on the accommodation portion <NUM>. The access hole communicates with the inner cavity. In this case, the key assembly may be mounted into the inner cavity through the access hole, and a part of the key assembly may protrude out of the inner cavity through the opening. In the case of adopting the above technical solution, the accommodation portion <NUM> is of an integrated structure. Structural strength of the accommodation portion is relatively high, thereby effectively protecting the key assembly mounted in the inner cavity, facilitating the processing of the snap slot <NUM> in the case that the snap slot <NUM> is disposed on the main body <NUM>, and improving precision of the snap slot <NUM>.

After the key assembly is mounted into the inner cavity through the access hole, the stopper <NUM> may be caused to block the access hole. That is, the inner cavity is caused to be in a relatively closed state through the stopper <NUM> and the accommodation portion <NUM>. With the stopper <NUM> detachably connected to the accommodation portion <NUM> and staying in a relatively fixed state, the key assembly is prevented from coming out of the access hole and being detached from the main body <NUM>. Specifically, the shape of the access hole may be adapted to the shape of the key assembly, and the stopper <NUM> may be caused to fully block the access hole, or, the stopper may be caused to block a part of the access hole. A detachable connection relationship may be formed, and relative fixing may be maintained, between the stopper <NUM> and the accommodation portion <NUM> by snap-fastening, plugging, connector connection, or other means. For example, a through-hole may be disposed on the stopper <NUM>. A threaded hole may be disposed on the accommodation portion <NUM>. By making the screw <NUM> pass through the through-hole and extend into the threaded hole, it is ensured that a steady detachable connection relationship is formed between the stopper <NUM> and the accommodation portion <NUM>.

Based on the above embodiment, in order to ensure that the key assembly can be mounted into the inner cavity from the access hole, as shown in <FIG>, in an axial direction of the access hole (equivalent to the rotation axis of the key assembly), at least a part of a projection of the inner cavity in the axial direction of the access hole needs to be located inside the access hole. That is, the projection of the inner cavity partly overlaps the projection of the access hole. In addition, as mentioned above, the key assembly needs to be capable of protruding out of the inner cavity through the opening. Therefore, as shown in <FIG>, a part of the projection of the access hole needs to be located outside the projection of the inner cavity in the axial direction of the access hole. In this way, when the key assembly is mounted into the inner cavity through the access hole, a part of the key assembly is necessarily located outside the inner cavity.

Under the above circumstance, in order to prevent the key assembly mounted in the inner cavity from moving relative to the main body <NUM> along the axial direction of the access hole, the stopper <NUM> may be connected to a position on the accommodation portion <NUM>, where the position serves as a boundary between the inner cavity and the access hole, such as a region in which the snap slot <NUM> is formed in the accommodation portion <NUM> as shown in <FIG>. The region is not only the boundary of the inner cavity, but also the boundary of the access hole.

Optionally, as shown in <FIG>, the accommodation portion <NUM> includes a function region 110b and an abutment region 110a that are connected to each other. The opening and the inner cavity are formed on the function region 110b. The abutment region 110a is located at a side of the opening, the side being away from the inner cavity. The abutment region 110a and the function region 110b together form the access hole. In addition, in order to ensure that the key assembly can protrude out of the inner cavity through the opening, the abutment region 110a needs to avoid the opening. For example, the abutment region 110a can avoid the opening by making the projection of the abutment region 110a along the axial direction of the opening be located outside the projection of the inner cavity. In a case that the accommodation portion <NUM> includes the abutment region 110a, a distance between the key assembly and the device body may be reduced. In this way, the user's finger may abut on the abutment region 110a during operation of the handle, thereby reducing the fatigue of the finger, preventing the user's fingers or skin from getting stuck in a gap between the key assembly and the device body, and further enhancing the user experience.

Based on the above embodiment, optionally, the stopper <NUM> is connected to the abutment region 110a. In this case, if the stopper <NUM> is of a flat plate-like structure, then, along the axial direction of the access hole, the distance between the stopper <NUM> and a surface oriented toward the stopper <NUM> in the inner cavity is necessarily greater than a dimension of the key assembly in said direction, and the key assembly can move relative to the accommodation portion <NUM> in the inner cavity along the axial direction of the access hole. Based on this, as shown in <FIG> and <FIG>, the stopper <NUM> includes an abutting portion <NUM> and a fixing portion <NUM>. The fixing portion <NUM> is detachably connected to the abutment region 110a, and can remain relatively fixed. The abutting portion <NUM> is fixed to one side of the fixing portion <NUM>. Along the rotation axis of the key assembly, the key assembly is disposed between the abutting portion <NUM> and the function region 110b in a position limiting manner. In this case, the key assembly is also prevented from shaking in the inner cavity, thereby enhancing overall performance of the handle, and in turn, enhancing the user experience.

Specifically, the fixing portion <NUM> and the abutting portion <NUM> may be formed in one piece to enhance the overall strength of the entire stopper <NUM>. A reliable fixing relationship may be formed between the fixing portion <NUM> and the abutment region 110a by snap-fastening, plugging, connector connection, or other means. The shape and dimensions of the abutting portion <NUM> may be set correspondingly based on the shape and dimensions of the access hole. The abutting portion <NUM> is caused to be in contact with the key assembly to achieve a position limiting effect for the key assembly.

As mentioned above, the key assembly includes a key <NUM>. Definitely, other structures still need to be included in the key assembly to provide a mounting foundation for the key <NUM>. Specifically, the key assembly may further include a positioning piece <NUM>. The snap slot <NUM> or the snap buckle <NUM> may be disposed on a sidewall in the positioning piece <NUM>, where the sidewall faces the inner wall of the inner cavity. At least a part of the positioning piece <NUM> is rotatably mounted in the inner cavity. The positioning piece <NUM> includes a mounting space. The positioning piece <NUM> further includes a captive hole that communicates with the mounting space. Through the captive hole, a part of the key <NUM> can protrude out of the mounting space to facilitate the user to press the key <NUM>.

To further enhance the pressing experience of the user, a keycap <NUM> may be disposed in the key assembly. The keycap <NUM> fits with the key <NUM>. The user can indirectly press and control the key <NUM> by pressing the keycap <NUM>. A part of the keycap <NUM> is disposed in the mounting space. Through the fit between the keycap <NUM> and the captive hole, the keycap <NUM> is prevented from being detached from the positioning piece <NUM>. Specifically, a circumferential dimension of the keycap <NUM> may be caused to gradually increase to prevent detachment of the keycap <NUM>. Correspondingly, another part of the keycap <NUM> may protrude out of the mounting space through the captive hole. Moreover, a part of the keycap <NUM> may be caused to protrude out of the opening, so that the user can control the key <NUM> by pressing the keycap <NUM>. Based on the above embodiment, the key <NUM> may be fully located inside the mounting space. Optionally, a surface of the keycap <NUM>, which is away from the key <NUM>, is an arcuate surface, so as to further enhance the effect of close fitting between the keycap <NUM> and the user and enhance the user experience.

More specifically, in order to ensure that the keycap <NUM> and the key <NUM> can be mounted into the mounting space of the positioning piece <NUM>, another hole may be formed on the positioning piece <NUM>. The keycap <NUM> is mounted into the mounting space through this hole. A part of the keycap <NUM> is caused to protrude out of the mounting space through the captive hole, and then the key <NUM> is mounted into the mounting space through this hole. A fixed connection relationship is formed between the key <NUM> and the positioning piece <NUM> by bonding or other means, so that both the keycap <NUM> and the key <NUM> are reliably mounted on the positioning piece <NUM>.

In another embodiment of this application, a flange may be disposed on a periphery of the keycap <NUM>, and the positioning piece <NUM> may include a base <NUM> and a cover <NUM>. The base <NUM> includes a first limiting edge. The cover <NUM> includes a second limiting edge. The base <NUM> is detachably connected to the cover <NUM>. The first limiting edge and the second limiting edge form a captive hole. In this case, the keycap <NUM> may be disposed to fit with the base <NUM> (or cover <NUM>) first, and then the cover <NUM> and the base <NUM> are assembled together. In this way, the first limiting edge and the second limiting edge limit the position of the flange of the keycap <NUM> to achieve an effect of preventing detachment of the keycap <NUM>, thereby reducing the difficulty of assembling the positioning piece <NUM> and the keycap <NUM> without a need to make other holes on the positioning piece <NUM>, and in turn, increasing the overall structural strength of the positioning piece <NUM>.

Specifically, the specific structure and dimensions of the base <NUM> and the cover <NUM> may be determined based on actual conditions, without being limited herein. A fixed connection relationship may be formed between the base <NUM> and the cover <NUM> by snap-fastening, connector connection, or other means. Alternatively, the base <NUM> and the cover <NUM> may be clasped together in the inner cavity of the main body <NUM>, so that the positions of the base <NUM> and the cover <NUM> are limited by means of surfaces oriented toward the base <NUM> and the cover <NUM> in the main body <NUM>. More specifically, the positions of the base <NUM> and the cover <NUM> may be restricted by the function region 110b and the abutting portion <NUM>, so as to prevent the keycap <NUM> from being detached from the positioning piece <NUM> due to detachment between the base and the cover.

Further, the base <NUM> may include a base body and a first supporting portion that are connected to each other. The cover <NUM> includes a cover body and a second supporting portion that are connected to each other. Both the first supporting portion and the second supporting portion are disposed toward the captive hole. The key <NUM> may be supported on the first supporting portion and the second supporting portion. In a case that the above technical solution is adopted, the reliability of the fixing relationship between the key <NUM> and the positioning piece <NUM> is further enhanced, thereby preventing failure to normally press the key caused by poor connection between the key <NUM> and the positioning piece <NUM> when the user presses the key <NUM> through the keycap <NUM>, and further enhancing the user experience.

Specifically, the base body, the first supporting portion, and the first limiting edge may be formed in one piece. Similarly, the cover body, the second supporting portion, and the second limiting edge may also be formed in one piece. The key <NUM> may be supported on the first supporting portion and the second supporting portion by bonding, snap-fastening, or other means.

In another embodiment of this application, a limiting groove is disposed on both the first supporting portion and the second supporting portion. The limiting grooves are recessed away from the captive hole. At least a part of the key <NUM> can be accommodated in the limiting groove and disposed in a position limiting manner in the limiting groove. In this case, on the one hand, the overall size of the key assembly is reduced. On the other hand, the position of the key <NUM> is limited reliably by the limiting groove, thereby preventing the reliability of the key <NUM> from being impaired by slippage of the key <NUM>. Specifically, the size and shape of the limiting groove may be determined correspondingly based on the size and shape of the key <NUM>. The reliability of the connection between the key <NUM> and the positioning piece <NUM> can be further enhanced by bonding or other means.

As mentioned above, the key assembly is rotatable relative to the main body <NUM>. Optionally, the inner wall of the main body <NUM> includes a first arcuate wall. A sidewall oriented toward the inner wall in the key assembly includes a second arcuate wall. The first arcuate wall is slidably in close fit with the second arcuate wall in the rotation direction of the key assembly, thereby providing guidance and position-limiting functions during rotation of the key assembly, and reducing difficulty of rotation of the key assembly. Specifically, as mentioned above, the key assembly may include a positioning piece <NUM>. The positioning piece <NUM> may include a base <NUM> and a cover <NUM>. As shown in <FIG> and <FIG>, a second arcuate wall may be disposed on both an outer edge of the base <NUM> and an outer edge of the cover <NUM>, and a first arcuate wall may be disposed on the accommodation portion <NUM> of the main body <NUM>. Parameters such as an arc length of the first arcuate wall and the second arcuate wall may be selected depending on actual needs, without being limited herein.

In addition, in a case that the above technical solution is adopted, when the user presses the key assembly, the main body <NUM> can also exert a supporting effect on the key assembly by means of the first arcuate wall and the second arcuate wall that are in close fit with each other. In this way, it is ensured that the pressing force of the user substantially acts on the key <NUM> and the main body <NUM>, without letting a large part of the force act on the snap buckle <NUM>, thereby further enhancing structural reliability and service life of the handle.

Optionally, the handle further includes a rotation shaft <NUM>. The main body <NUM> includes a fitting groove <NUM>. The key assembly is rotatably connected to the main body <NUM> through the rotation shaft <NUM>. Under the action of the rotation shaft <NUM>, on the other hand, the difficulty of relative rotation between the key assembly and the main body <NUM> is reduced. On the other hand, failure to continuous relative rotation or relative movement between the key assembly and the main body is prevented in a case of mutual misalignment between the key assembly and the main body <NUM>. In addition, the rotation shaft <NUM> is movably in fit with the fitting groove <NUM> along the axial direction of the opening, so that the key assembly can still move relative to the main body <NUM> along the axial direction of the opening, and so that the snap buckle <NUM> is disengaged from or engaged with the snap slot <NUM>, thereby ensuring that the key assembly is still adjustable.

Specifically, the fitting groove <NUM> may be formed on two surfaces opposite to the key assembly in the main body <NUM>. As mentioned above, the main body <NUM> may include an accommodation portion <NUM> and a stopper <NUM>. Therefore, the fitting groove <NUM> may be disposed on both the accommodation portion <NUM> and a stopper <NUM>. By making the size of the fitting groove <NUM> along the axial direction of the opening be larger than the size of the rotation shaft <NUM>, it is ensured that the key assembly can drive the rotation shaft <NUM> to move inside the fitting groove <NUM> along the axial direction of the opening, thereby achieving the purpose of relative movement against the main body <NUM>.

Based on the above embodiment, as mentioned above, the key assembly may include a positioning piece <NUM>. The positioning piece <NUM> may include a base <NUM> and a cover <NUM>. In a case that the handle includes a rotation shaft <NUM>, a through-hole may be disposed on both the base <NUM> and the cover <NUM>. The rotation shaft <NUM> passes through the two through-holes, and is connected to the accommodation portion <NUM> and the stopper <NUM>.

Further, the snap buckle <NUM> or the snap slot <NUM> may be disposed on the base <NUM>, and the cover <NUM> may be connected to the resetting piece. In this case, mutual interference between the resetting piece and the snap buckle <NUM> can be prevented, and the connection relationship can be designed by making better use of structures, thereby enhancing the structural optimization degree of the entire key assembly and utilizing space more efficiently.

As mentioned above, the resetting piece may include a first magnetic assembly <NUM> and a second magnetic assembly <NUM>. Optionally, one of the first magnetic assembly <NUM> or the second magnetic assembly <NUM> may be mounted on the cover <NUM>, and the other of the first magnetic assembly or the second magnetic assembly may be mounted on the accommodation portion <NUM>. A mounting groove <NUM> may be disposed at a position corresponding to the cover <NUM> on the accommodation portion <NUM>, so as to enable mounting of the first magnetic assembly <NUM> or the second magnetic assembly <NUM>. Similarly, a corresponding groove structure may also be disposed on the cover <NUM>. As mentioned above, one of the first magnetic assembly <NUM> or the second magnetic assembly <NUM> may be an arcuate structural piece. For example, the first magnetic assembly <NUM> or the second magnetic assembly <NUM>, whichever is mounted on the cover <NUM>, is of an arcuate structure. Therefore, a middle region of the groove structure disposed on the cover <NUM> may be of an open structure. That is, a part of the groove structure, which is oriented toward the region in which the mounting groove <NUM> is located, is a bottomless structure. This can reduce the distance between the first magnetic assembly <NUM> and the second magnetic assembly <NUM> to some extent, thereby reducing the overall size of the key assembly and enhancing the adsorption effect between the first magnetic assembly <NUM> and the second magnetic assembly <NUM>.

Based on the handle disclosed in any one of the above embodiments, this application further discloses an electronic device. The electronic device includes a device body and the handle. The device body may include a display screen. The handle is connected to the device body. Specifically, the handle may be mounted on the device body by magnetic adsorption, bonding, or other means. Alternatively, as mentioned above, the entire handle may be snap-fastened and mounted onto the device body through a claw <NUM> connected to the main body <NUM>. In addition, the device body may be connected to the handle by a wire, or through wireless communication such as Bluetooth. In this way, when the user controls the handle, the control information may be transmitted to the device body to generate a corresponding operation and/or command.

The electronic device disclosed in an embodiment of this application may be a smartphone, a tablet computer, an e-book reader, or a wearable device. Alternatively, the electronic device may be another device, without being limited in this embodiment of this application.

The above embodiments of this application are described by focusing on the differences between the embodiments. Different technical features optimized based on various embodiments may be combined to form an optimized embodiment as long as the features do not conflict with each other.
