Patent Description:
With the progress of technologies and the development of electronic devices, users' demands for the screen-to-body ratio of the electronic devices are gradually increasing, and increasing the screen-to-body ratio of the electronic devices has gradually become a development trend. A relatively large screen-to-body ratio causes the electronic devices to have some functional modules embedded inside the electronic devices. When a functional module needs to work, the functional module may be driven by a driving mechanism to extend out of the shell of the electronic devices to work. The functional module with such a structure does not occupy the panel surface space of the electronic devices, so as to enable an increase of the screen-to-body ratio.

In addition, the functional modules of the existing electronic devices can only work at extended positions and have the problem of poor flexibility in use.

Accompanying drawings described herein are used for providing further understanding about the present invention, and constitute one portion of the present invention. Exemplary embodiments of the present invention and descriptions thereof are used for explaining the present invention, and do not constitute an inappropriate limitation on the present invention. In the accompanying drawings:.

To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention are described clearly and thoroughly below with reference to specific embodiments of the present invention and corresponding accompanying drawings. Apparently, the described embodiments are merely some embodiments rather than 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 creative efforts shall fall within the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described below in detail with reference to the accompanying drawings.

As shown in <FIG>, an electronic device is disclosed in this embodiment of the present invention. The disclosed electronic device includes a device body <NUM>, a functional module <NUM>, and an ejection mechanism.

The device body <NUM> is provided with a first accommodating space <NUM>, a second accommodating space <NUM>, and a first opening <NUM> in communication with the first accommodating space <NUM>. The second accommodating space <NUM> is in communication with the first accommodating space <NUM>. Specifically, the second accommodating space <NUM> has a second opening. The first accommodating space <NUM> is in communication with the second accommodating space <NUM> through the second opening. The first accommodating space <NUM> can provide a mounting position for the functional module <NUM>. The functional module <NUM> can retract into the first accommodating space <NUM> through the first opening <NUM>. Alternatively, at least a part of the functional module <NUM> can extend out of the first accommodating space <NUM> through the first opening <NUM>. The second accommodating space <NUM> can provide a mounting position for the ejection mechanism. The first opening <NUM> may be provided on a second shell <NUM> of the device body <NUM>. Optionally, the first opening <NUM> may be provided on a middle frame of the second shell <NUM>. The first opening <NUM> may also be provided at another position of the second shell <NUM>. A specific position of the first opening <NUM> is not limited in the embodiments of the present invention.

The functional module <NUM> may include at least one of a camera, a light filling module, a fingerprint identification module, a microphone, an electrical connection port, a data card, and a phone receiver. Certainly, the functional module <NUM> may also be another type of functional device. A specific type of the functional module <NUM> is not limited in the embodiments of the present invention.

The ejection mechanism includes a connecting rod <NUM>, a slider <NUM>, and a driving part <NUM>. The functional module <NUM> is detachably connected to the slider <NUM>. A guide rail <NUM> is disposed on the slider <NUM>. The guide rail <NUM> includes a first limiting section <NUM>, an extending section <NUM>, a second limiting section <NUM>, and a retracting section <NUM> connected in sequence. Both the extending section <NUM> and the retracting section <NUM> implement the function of connecting the first limiting section <NUM> and the second limiting section <NUM>. Specifically, one end of the first limiting section <NUM> is connected to an opposite end of the second limiting section <NUM> by the extending section <NUM>, and the other end of the first limiting section <NUM> is connected to an opposite end of the second limiting section <NUM> by the retracting section <NUM>.

In a specific installation process, at least a part of the driving part <NUM> is disposed inside the second accommodating space <NUM>, and the driving part <NUM> can drive the slider <NUM> to move along a direction perpendicular to the first opening <NUM>. In a case that the functional module <NUM> is connected to the slider <NUM>, the driving part <NUM> can drive the slider <NUM> to move and make at least a part of the slider <NUM> extend out of the second accommodating space <NUM> through the second opening, so as to push the functional module <NUM> to move and make at least a part of the functional module <NUM> extend out of the first accommodating space <NUM> through the first opening <NUM>. The driving part <NUM> may be a spiral telescopic spring or an elastic rubber element. A specific type of the driving part <NUM> is not limited in the embodiments of the present invention.

A first end of the connecting rod <NUM> is hinged to an inner wall of the second accommodating space <NUM>, and a second end of the connecting rod <NUM> is slidably matched with the guide rail <NUM>, so that the second end of the connecting rod <NUM> slides to respective parts of the guide rail <NUM> during the movement of the slider <NUM>. Specifically, the first end of the connecting rod <NUM> is rotated, to enable the second end of the connecting rod <NUM> to adaptively is slidably matched with the first limiting section <NUM>, the extending section <NUM>, the second limiting section <NUM>, and the retracting section <NUM>. Both the matching between the second end of the connecting rod <NUM> and the first limiting section <NUM>, and the matching between the second end of the connecting rod <NUM> and the second limiting section <NUM> can maintain the slider <NUM> at a specified position. In this case, in a case that the slider <NUM> is connected to the functional module <NUM>, the functional module <NUM> can be maintained by the slider <NUM> at an extending position and a retracting position that are described above.

Optionally, the first limiting section <NUM> may include a first sub-limiting section and a second sub-limiting section. The first sub-limiting section and the second sub-limiting section are disposed spaced apart. The second limiting section <NUM> may be a broken-line limiting section. One end of the first sub-limiting section is connected to a first end of the broken-line limiting section by the extending section <NUM>, and one end of the second sub-limiting section is connected to a second end of the broken-line limiting section by the retracting section <NUM>. Further, in an optional implementation, the extending section <NUM> and the retracting section <NUM> may be disposed opposite to each other and inclinedly. A distance between one end of the extending section <NUM> close to the first sub-limiting section and one end of the retracting section <NUM> close to the second sub-limiting section is a first distance, and a distance between one end of the extending section <NUM> close to the broken-line limiting section and one end of the retracting section <NUM> close to the broken-line limiting section is a second distance, where the first distance is smaller than the second distance, so that a part of the guide rail <NUM> may be in an "M"-shaped structure. In this embodiment of the present invention, the extending section <NUM> and the retracting section <NUM> are disposed inclinedly, to guide the second end of the connecting rod <NUM> better, so that the second end of the connecting rod <NUM> has smaller resistance when moving between the first limiting section <NUM> and the second limiting section <NUM>, and slides more steadily, thereby preventing the second end of the connecting rod <NUM> from being suck during movement.

Optionally, as shown in <FIG>, the guide rail <NUM> may be an annual rail. Specifically, a first end of the first limiting section <NUM> is connected to the extending section <NUM>, and a second end of the first limiting section <NUM> is connected to the retracting section <NUM>. A first end of the second limiting section <NUM> is connected to the extending section <NUM>, and a second end of the second limiting section <NUM> is connected to the retracting section <NUM>. In this case, when the slider <NUM> is connected to the functional module <NUM>, in a case that the functional module <NUM> is continuously pressed by a user, the second end of the connecting rod <NUM> can slide relative to the guide rail <NUM>. Referring to <FIG> again (the arrow in the figure refers to a movement direction of the second end of the connecting rod <NUM>), the second end of the connecting rod <NUM> can enter the retracting section <NUM> from the first limiting section <NUM>, enter the second limiting section <NUM> from the retracting section <NUM>, enter the extending section <NUM> from the second limiting section <NUM>, and enter the first limiting section <NUM> from the extending section <NUM>, and repeat the process in sequence as being pressed. The extending section <NUM> and the retracting section <NUM> implement a guiding function, to cause the second end of the connecting rod <NUM> to switch between matching the first limiting section <NUM> and matching the second limiting section <NUM>, so that the movement of the second end of the connecting rod <NUM> is smoother.

In this embodiment of the present invention, the functional module <NUM> has a first state and a second state. In a case that the functional module <NUM> is in the first state, the functional module <NUM> is separated from the slider <NUM>. In this case, the functional module <NUM> may be separated from the device body <NUM>, so that the functional module <NUM> can work away from the device body <NUM>.

In a case that the functional module <NUM> is in the second state, the functional module <NUM> is connected to the slider <NUM>, and the slider <NUM> is movable between a first position and a second position.

Specifically, when the slider <NUM> is at the first position, the slider <NUM> is located inside the second accommodating space <NUM>, and the second end of the connecting rod <NUM> is matched with the second limiting section <NUM> to restrict the slider <NUM> from moving toward the first opening <NUM>. The matching between the second end of the connecting rod <NUM> and the second limiting section <NUM> can maintain the slider <NUM> at the first position. When the slider <NUM> is at the second position, at least a part of the slider <NUM> is located outside the second accommodating space <NUM>, and the second end of the connecting rod <NUM> is matched with the first limiting section <NUM> to restrict the slider <NUM> from moving toward the first opening <NUM>. The matching between the second end of the connecting rod <NUM> and the first limiting section <NUM> can maintain the slider <NUM> at the second position. An acting force generated by the second end of the connecting rod <NUM> on the slider <NUM> is opposite to an acting force generated by the driving part <NUM> on the slider <NUM>, so that the slider <NUM> can be maintained at a corresponding position.

Based on this, since the functional module <NUM> is connected to the slider <NUM>, in a case that the slider <NUM> is at the second position, at least a part of the functional module <NUM> is located outside the first accommodating space <NUM>. In a case that the slider <NUM> is at the first position, the functional module <NUM> is located inside the first accommodating space <NUM>. Therefore, the functional module <NUM> can be maintained at a corresponding position by maintaining the slider <NUM> at a corresponding position.

In use, after the functional module <NUM> finishes working, the user may manually press the functional module <NUM>. Further, the functional module <NUM> enables the slider <NUM> to overcome the acting force of the driving part <NUM>. The second end of the connecting rod <NUM> can slide from the first limiting section <NUM> through the retracting section <NUM> to a position at which the second end of the connecting rod <NUM> is matched with the second limiting section <NUM>. The slider <NUM> is located at the first position to make the functional module <NUM> be located inside the first accommodating space <NUM>. Under the action of the acting force of the driving part <NUM> and the matching of the second limiting section <NUM>, the functional module <NUM> can be maintained at the position inside the first accommodating space <NUM>. When needing the functional module <NUM> to work, the user may press the functional module <NUM> again, to enable the slider <NUM> to overcome the acting force of the driving part <NUM>. The second end of the connecting rod <NUM> may slide from the second limiting section <NUM> through the extending section <NUM> to a position at which the second end of the connecting rod <NUM> is matched with the first limiting section <NUM>. At the same time, the slider <NUM> drives the functional module <NUM> to make at least a part of the functional module <NUM> extend out of the first accommodating space <NUM> through the first opening <NUM>. Under the action of the acting force of the driving part <NUM> and the matching of the second limiting section <NUM>, the slider <NUM> can be maintained at the first position. In this case, at least a part of the functional module <NUM> may be maintained at a position inside the first accommodating space <NUM>, and the functional module <NUM> may also be separated from the slider <NUM>, so that the functional module <NUM> can work away from the device body <NUM>.

It can be seen from the above working process that in the electronic device disclosed in the embodiments of the present invention, the functional module <NUM> is detachably connected to the slider <NUM>. The functional module <NUM> can extend out of the first accommodating space <NUM> or retract into the first accommodating space <NUM> through the slider <NUM>. Compared with that the functional module <NUM> of the existing electronic device needs to be connected to components, such as a driving motor and a speed reducer, to move, in the disclosed embodiments of the present invention, the functional module <NUM> and the slider <NUM> can be in a separated state, so that the functional module <NUM> not only can work outside the first accommodating space <NUM>, but also can work separately from the device body <NUM>. In addition, the user only needs to press the functional module <NUM> to implement installation and removal of the functional module <NUM>, thereby facilitating driving of the functional module <NUM> and further improving the flexibility of the functional module <NUM>.

Correspondingly, the above ejection mechanism is a manual driving mechanism, which enables the functional module <NUM> to enter and exit the first accommodating space <NUM> without power consumption, so that the power consumption of the entire electronic device can be reduced. In addition, both the functional module <NUM> and the ejection mechanism have an independent installation space, so that the ejection mechanism drives the functional module <NUM> relatively steadily.

Further, to enable the ejection mechanism to drive the functional module <NUM> more steady, in an optional solution, the ejection mechanism may further include a connecting base <NUM>. The connecting base <NUM> may be connected to the slider <NUM>, and the slider <NUM> is detachably connected to the functional module <NUM> by the connecting base <NUM>. In this case, the slider <NUM> may drive, through the connecting base <NUM>, the functional module <NUM> to move. It should be noted that in a telescopic direction of the functional module <NUM>, the projection area of the connecting base <NUM> is larger than the projection area of the slider <NUM>. In this case, compared with a contact area between the slider <NUM> and the functional module <NUM>, the contact area between the connecting base <NUM> and the functional module <NUM> is larger, so that the driving forces of the connecting base <NUM> on positions of the functional module <NUM> are evener, thereby enabling the slider <NUM> to drive the functional module <NUM> more steadily.

Optionally, in a case that the functional module <NUM> is in the first state, the connecting base <NUM> may be hermetically connected to the first opening <NUM>. In this case, the connecting base <NUM> may block the first opening <NUM>, so that the first accommodating space <NUM> and the second accommodating space <NUM> form a sealed space, thereby implementing a water-proof and dust-proof function. Optionally, a seal ring may be disposed between the connecting base <NUM> and the first opening <NUM>, the connecting base <NUM> may be hermetically connected to the first opening <NUM> by the seal ring. Certainly, the connecting base <NUM> may also be hermetically connected to the first opening <NUM> in various manners. A specific manner in which the connecting base <NUM> is hermetically connected to the first opening <NUM> is not limited in the embodiments of the present invention.

Further, in a case that the functional module <NUM> is in the first state, an outer surface of the connecting base <NUM> is flush with an outer surface at which the first opening <NUM> is located. In this case, when the functional module <NUM> is separated from the device body <NUM>, the connecting base <NUM> blocks the first opening <NUM>, and an outer surface of the connecting base <NUM> is flush with the outer surface at which the first opening <NUM> is located, which not only implements the water-proof and dust-proof function, but also makes the appearance of the electronic device better.

Correspondingly, in a case that the ejection mechanism includes the connecting base <NUM>, a first electrical interface <NUM> may be disposed on the functional module <NUM>, a second electrical interface <NUM> may be disposed on one side of the connecting base <NUM> facing away from the slider <NUM>, and a third electrical interface <NUM> may be disposed on one side of the connecting base <NUM> facing the slider <NUM>. The second electrical interface <NUM> is electrically connected to the third electrical interface <NUM>. A fourth electrical interface <NUM> may be disposed in the first accommodating space <NUM>. In a case that the functional module <NUM> is located inside the first accommodating space <NUM>, the first electrical interface <NUM> may be electrically connected to the second electrical interface <NUM>, and the third electrical interface <NUM> may be electrically connected to the fourth electrical interface <NUM>. In conclusion, in this way, the functional module <NUM> may be electrically connected to the device body <NUM>, so that the functional module <NUM> can implement functions such as data transmission and charging.

In the embodiments of the present invention, the functional module <NUM> may be detachably connected to the connecting base <NUM> in various manners. For example, the functional module <NUM> may be connected to the connecting base <NUM> in a manner such as engagement, a threaded connection, or magnetic attraction. Optionally, a first magnetic part <NUM> may be disposed on one of the functional module <NUM> or one side of the connecting base <NUM> facing away from the slider <NUM>, and a second magnetic part <NUM> may be disposed on the other thereof. In a case that the functional module <NUM> is in the second state, the first magnetic part <NUM> is magnetically connected to the second magnetic part <NUM>. Compared with other manners, such a manner not only facilitates the connection between the functional module <NUM> and the connecting base <NUM>, but also helps the user to relatively easily take out the functional module <NUM> from the first accommodating space <NUM>.

Further, the first magnetic part <NUM> may be disposed on the functional module <NUM>, and the second magnetic part <NUM> may be disposed on the one side of the connecting base <NUM> facing away from the slider <NUM>. In addition, the second magnetic part <NUM> may be an electromagnet. In a case that the functional module <NUM> is located inside the first accommodating space <NUM>, in view of the above, the connecting base <NUM> may be electrically connected to the fourth electrical interface <NUM> through the third electrical interface <NUM>. Therefore, the second magnetic part <NUM> on the connecting base <NUM> is energized to generate magnetic attraction, so that the first magnetic part <NUM> is magnetically connected to the second magnetic part <NUM>, so that the functional module <NUM> can be maintained in the first accommodating space <NUM>. In addition, in a case that at least a part of the slider <NUM> is located outside the second accommodating space <NUM>, the second magnetic part <NUM> on the connecting base <NUM> is not energized, so that there is no magnetic attraction between the first magnetic part <NUM> and the second magnetic part <NUM>, thereby enabling the user to relatively easily take out the functional module <NUM> from the first accommodating space <NUM>.

In the embodiments of the present invention, in an optional solution, the driving part <NUM> may be an elastic member. One end of the elastic member may be connected to the inner wall of the second accommodating space <NUM>, and the other end of the elastic member may be connected to the slider <NUM>. Compared with the driving part <NUM> with another structure, the elastic member has a larger elastic deformation capability, which makes it easier to drive the slider <NUM>. In addition, in a case that the driving part <NUM> is an elastic member, the service life of the driving part <NUM> can further be prolonged. The elastic member may be a telescopic spring. Certainly, the elastic member may also be another elastic component. A specific structure of the elastic member is not limited in the present invention.

In an actual assembly process, to improve the assembly performance, in an optional solution, a first guide post <NUM> may be disposed on the inner wall of the second accommodating space <NUM>, and a second guide post <NUM> may be disposed on the slider <NUM>. One end of the elastic member overlaps with the first guide post <NUM>, and the other end of the elastic member overlaps with the second guide post <NUM>, so as to facilitate the installation and removal of the elastic member.

In this embodiment of the present invention, in another optional solution, the driving part <NUM> may include a third magnetic part and a fourth magnetic part. The third magnetic part may be disposed inside the second accommodating space <NUM>, and the fourth magnetic part may be connected to the slider <NUM>. The third magnetic part and the fourth magnetic part are disposed opposite to each other, and the third magnetic part has the same magnetic property as the fourth magnetic part. In this case, an acting force toward the first opening <NUM> is generated due to the repulsion between the third magnetic part and the fourth magnetic part that have the same magnetic property, thereby indirectly causing the slider <NUM> to have an acting force toward the first opening <NUM>, and eventually, drive the slider <NUM>. In this way, the driving forces received by the slider <NUM> are evener, so that the movement of the slider <NUM> is more steady.

In the embodiments disclosed in the present invention, the second end of the connecting rod <NUM> maintains the position of the slider <NUM>, and there may be various specific structures of the second end of the connecting rod <NUM>. In an optional solution, the second end of the connecting rod <NUM> may be a retractor. The retractor is hung on the guide rail <NUM>. The retractor is hung on the first limiting section <NUM> and the second limiting section <NUM> respectively to be matched with the first limiting section <NUM> and the second limiting section <NUM> respectively in a limiting manner. Specifically, in a case that at least a part of the functional module <NUM> is located outside the first accommodating space <NUM>, the retractor is hung on and is matched with the first limiting section <NUM>, and in this case, at least part of the slider <NUM> is located outside the second accommodating space <NUM>. In a case that the functional module <NUM> is located inside the first accommodating space <NUM>, the retractor is hung on and is matched with the second limiting section <NUM>, and in this case the slider <NUM> is located inside the second accommodating space <NUM>. In this case, the second end of the connecting rod <NUM> is disposed between the first opening <NUM> and the first end of the connecting rod <NUM>. The connecting rod <NUM> exerts a pulling force on the slider <NUM>, so as to restrict the slider <NUM> from moving toward the extending direction of the functional module <NUM>, so that the slider <NUM> can be maintained at the first position or the second position. Both the first limiting section <NUM> and the second limiting section <NUM> may be concave, to be conveniently hung on by the retractor in a limiting manner.

Certainly, in the above embodiments, the first end of the connecting rod <NUM> is located on one side of the slider <NUM> facing away from the first opening <NUM>, so that the entire connecting rod <NUM> is closer to a central region of the device body <NUM>. Since a circuit board and many electronic components disposed in the central region of the device body <NUM>, the connecting rod <NUM> is likely to interfere with the circuit board or the electronic components. Therefore, in another optional solution, the second end of the connecting rod <NUM> may be an abutting part, and the abutting part abuts against the guide rail <NUM>. Specifically, in a case that at least a part of the functional module <NUM> is located outside the first accommodating space <NUM>, the abutting part abuts against the second limiting section <NUM>, and in this case, the slider <NUM> is located outside the second accommodating space <NUM>. In a case that the functional module <NUM> is located inside the first accommodating space <NUM>, the abutting part abuts against the first limiting section <NUM>, and in this case, the slider <NUM> is located inside the second accommodating space <NUM>. In this case, the first end of the connecting rod <NUM> is located between the first opening <NUM> and the second end of the connecting rod <NUM>. The acting force exerted by the abutting part on the slider <NUM> may be a thrust force. Similarly, both the first limiting section <NUM> and the second limiting section <NUM> may be concave, to be conveniently abutted against by the abutting part in a limiting manner. The first limiting section <NUM> and the second limiting section <NUM> may also be of other structures provided that the abutting part can be matched with the first limiting section <NUM> and the second limiting section <NUM> in a limiting manner, so that the slider <NUM> can be maintained at the first position or the second position under the limitation of the abutting part.

As can be learned from the above, in this manner, the first end of the connecting rod <NUM> is located on one side of the slider <NUM> facing the first opening <NUM>, so that the connecting rod <NUM> is closer to an edge of the device body <NUM>. Since there are fewer electronic components distributed on the edge of the device body <NUM>, the connecting rod <NUM> can be prevented from interfering with the electronic components in the device body <NUM>.

In the embodiments of the present invention, the first limiting section <NUM>, the extending section <NUM>, the second limiting section <NUM>, and the retracting section <NUM> may be a groove section with various structures. Referring to <FIG>, the extending section <NUM> may be a straight groove section, so that the functional module <NUM> can extend more quickly. Optionally, the retracting section <NUM> may include an arc-shaped groove section. Since the functional module <NUM> needs to be pressed by the user for a longer time during retraction, an arc-shaped groove section has a certain curvature to better guide the second end of the connecting rod <NUM> to a position at which the second end of the connecting rod <NUM> is matched with the first limiting section <NUM>.

The guide rail <NUM> may also be another structure and not limited to a grooveshaped structure. In one specific embodiment, the guide rail <NUM> may be a convex guide part. Specifically, referring to <FIG>, the convex guide part may include a first annular protrusion <NUM> and a second annular protrusion <NUM>, and a region between the first annular protrusion <NUM> and the second annular protrusion <NUM> is the guide rail <NUM>. In this case, the first limiting section <NUM>, the extending section <NUM>, the second limiting section <NUM>, and the retracting section <NUM> all may be at least a part of the region between the first annular protrusion <NUM> and the second annular protrusion <NUM>. During working, a sliding stroke of the second end of the connecting rod <NUM> may be as shown in <FIG>, and a direction in which the second end of the connecting rod <NUM> slides relative to the guide rail <NUM> is schematically shown by a dashed arrow in <FIG>. In this way, the sliding of the second end of the connecting rod <NUM> is smoother, thereby preventing the second end of the connecting rod <NUM> from being stuck during movement. Certainly, the first annular protrusion <NUM> and the second annular protrusion <NUM> may be formed by injection molding or in another manner. A specific forming manner of the first annular protrusion <NUM> and the second annular protrusion <NUM> is not limited in the present invention.

In the embodiments of the present invention, during the movement of the slider <NUM>, the second end of the connecting rod <NUM> may be disengaged from the guide rail <NUM>. Therefore, to achieve more steady sliding and matching, the device body <NUM> may further include a first shell <NUM>. The first shell <NUM> may be provided with a sliding cavity. At least a part of the slider <NUM> may be located in the sliding cavity and at least a part of the connecting rod <NUM> may be located in the sliding cavity. In this case, the second end of the connecting rod <NUM> may slide inside the sliding cavity, so that the second end of the connecting rod <NUM> is prevented from being disengaged from the guide rail <NUM>, thereby improving the sliding stability of the second end of the connecting rod <NUM>.

Further, to enable the second end of the connecting rod <NUM> to better slide in the guide rail <NUM>, the first shell <NUM> may include an elastic arm <NUM>. At least a part of the connecting rod <NUM> may be located between the elastic arm <NUM> and the guide rail <NUM>. In this case, due to the elastic effect of the elastic arm <NUM>, the second end of the connecting rod <NUM> can better slide in the guide rail <NUM>, thereby preventing the second end of the connecting rod <NUM> from being disengaged from the guide rail <NUM>.

After the above structure is adopted, at least a part of the connecting rod <NUM> may slide between the elastic arm <NUM> and the guide rail <NUM>. Based on this, optionally, the elasticity of the elastic arm <NUM> enables the second end of the connecting rod <NUM> to snugly fit the guide rail <NUM>, so that the second end of the connecting rod <NUM> can be prevented from swinging between the elastic arm <NUM> and the guide rail <NUM>, thereby better preventing the second end of the connecting rod <NUM> from being disengaged from the sliding of the guide rail <NUM>.

In the electronic device disclosed in the embodiments of the present invention, the functional module <NUM> can be separated from the device body <NUM>, and the device body <NUM> can remotely control the functional module <NUM> to work. In a case that the functional module <NUM> is separated from the device body <NUM>, the first accommodating space <NUM> and the second accommodating space <NUM> may come into contact with an external environment, which is not conducive to the water-proof and dust-proof performance of the electronic device. Therefore, in one optional solution, the device body <NUM> may include a second shell <NUM>. The second shell <NUM> has an inner cavity. The second shell <NUM> may include a separator <NUM>. The separator <NUM> may be disposed inside the inner cavity. The separator <NUM> separates the inner cavity into a first sub-cavity, a second sub-cavity, and a third sub-cavity. The first sub-cavity and the second sub-cavity is hermetically separated from the third sub-cavity. The first sub-cavity is in communication with the second sub-cavity. The first sub-cavity is the first accommodating space <NUM>, and the second sub-cavity is the second accommodating space <NUM>. In this way, impurities can be prevented from entering into the inner space of the device body <NUM> through the first accommodating space <NUM> or the second accommodating space <NUM>, thereby producing better water-proof and dust-proof effects.

The volume of the functional module <NUM> is generally small. When the functional module <NUM> is separated from the device body <NUM>, the functional module <NUM> is easily lost. Therefore, the functional module <NUM> may include a functional module body and a sling, and the functional module body may be provided with a sling hole <NUM>. The sling may be detachably connected to the functional module body by the sling hole <NUM>. In this case, when the functional module body is separated from the device body <NUM>, the user can carry the functional module body through the sling, thereby preventing the functional module body from being lost.

The electronic device disclosed in the embodiments of the present invention may be a device such as a smartphone, a tablet computer, an e-book reader, a wearable device, or an electronic game console. A specific type of the electronic device is not limited in the embodiments of the present invention.
