The electronic device such as the mobile phone with small display screen has limitations for watching movies, games, entertainment or office, and user experience is poor in some application scenarios requiring a large interactive screen, such as movie watching and game interaction. In addition, the electronic device such as the mobile phone is generally equipped with an optical lens for taking pictures. The optical lens is usually long in length to achieve desirable imaging performance, which limits the arrangement of components on the mainboard to a certain extent, making the electronic device to be bulky and not portable.

In the embodiments of the disclosure, the electronic device <NUM> is configured with the display screen <NUM> that is combined with the housing <NUM> and is drawn into or out of the housing <NUM>, and the camera module <NUM> accommodated in the housing <NUM>, so as to enable a user to switch, according to the usage scenario, a state of the display screen <NUM> when using the electronic device <NUM>. In addition, the camera module <NUM> is configured with the reflective element <NUM> and the lens components which is adjusted to a first operation mode or a second operation mode, so that the electronic device <NUM> is equipped with a large area display screen <NUM> in the expanded state and a small area display screen <NUM> with a short lateral length in the accommodated state. In this way, the electronic device <NUM> can be used in various application scenarios, so as to meet diversified usage requirements of the user proposed on the electronic device <NUM> while enabling the electronic device <NUM> with a short lateral length in the first operation mode, thereby facilitating the miniaturization of the electronic device <NUM> in the accommodated state and enabling the electronic device <NUM> of the disclosure to be portable.

Specifically, the housing <NUM> may include the first housing <NUM> and the second housing <NUM>. As illustrated in <FIG>, the reel <NUM> is disposed on the first side <NUM> of the first housing <NUM>, the second housing <NUM> is connected with the second side <NUM> of the first housing <NUM> into which the second housing <NUM> is relatively movably inserted, the first side <NUM> is opposite to the second side <NUM>, the first end of the display screen <NUM> is fixedly connected to the upper surface <NUM> of the second housing <NUM>, the second end of the display screen <NUM> is wound around the reel <NUM>, and the display screen <NUM> is movable along the upper surface <NUM> of the first housing <NUM> under driving of the movement of the second housing <NUM>. Hereinafter, the upper surface <NUM> of the second housing <NUM> and the upper surface <NUM> of the first housing <NUM> refer to a front surface of the electronic device <NUM>, i.e., a surface facing z direction in <FIG>. In the embodiments of the disclosure, the electronic device <NUM> may be configured to control the second housing <NUM> to approach or move away from the first housing <NUM> to thereby drive the display screen <NUM> to move along the upper surface <NUM> of the first housing <NUM>, so as to enable the display screen <NUM> to be expanded (i.e., unfolded) or folded, that is, a function of drawing the display screen <NUM> out of or into the housing <NUM> is achieved. Specifically, the display screen <NUM> gradually expanded out of the reel <NUM> as the second housing <NUM> moves away from the first housing <NUM>, and the display screen <NUM> is gradually accommodated into the reel <NUM> as the second housing <NUM> moves towards the first housing <NUM>.

The display screen <NUM> may be a flexible display screen <NUM>, which may include a flexible organic light emitting diode (OLED) panel and a plastic substrate, so that the flexible display screen <NUM> may be accommodated in the housing <NUM> and wound around the reel <NUM> to present three different states including the accommodated state, the expanded state, and the partially expanded state. Correspondingly, cooperation states of the first housing <NUM> and the second housing <NUM> also includes three states including an accommodated state, an expanded state, and a partially expanded state. The display screen <NUM> is drawn into or out of the housing <NUM>, that is, the display screen <NUM> is switched from the three different states, i.e., the accommodated state, the expanded state, and the partially expanded state.

When the display screen <NUM> is in the accommodated state, a portion of the display screen <NUM> which is capable of being accommodated is completely wound around the reel <NUM>. When the display screen <NUM> is in the partially expanded state, i.e., a partially accommodated state, a part of the portion of the display screen <NUM> which is capable of being accommodated is wound around the reel <NUM>, and the other part of the portion of the display screen <NUM> is released from the reel <NUM> to be located outside the housing <NUM>. When the display screen <NUM> is in the expanded state, portion of the display screen <NUM> which is capable of being wound around the reel <NUM> is completely expanded out of the housing <NUM>. According to the embodiments of the disclosure, the display screen <NUM> has three different states, i.e., the accommodated state, the expanded state, and the partially expanded state, which is facilitated to enable the electronic device <NUM> to be switched between the expanded state where the display screen <NUM> has the large area, the accommodated state where the display screen <NUM> has the small area and the short lateral length, and the partially expanded state where the area of the display screen <NUM> is greater than that of the accommodated state while less than that of the expanded state. In this way, the display screen <NUM> may be in different states according to different usage scenarios, so as to meet the diversified usage requirements of the user proposed on the electronic device <NUM>, and improve the user experience. When the display screen <NUM> is accommodated in the housing <NUM>, the electronic device is as portable as a conventional cell phone. When the display screen <NUM> is partially or completely expanded, the electronic device <NUM> is enabled with both entertainment and office functions, which is similar to the tablet computer, so as to cater to a current consumer demand for both of portability and multi-function.

Referring to <FIG>, the first accommodation cavity <NUM> is formed inside the first housing <NUM>, and the second accommodation cavity <NUM> is formed inside the second housing <NUM>. When the second housing <NUM> moves away from the first housing <NUM> since the accommodated state, a space between the first accommodation cavity <NUM> and the second accommodation cavity <NUM> forms a third accommodation cavity <NUM>. A right side of the first accommodation cavity <NUM> is open, a left side of the second accommodation cavity <NUM> is open, and a left side and a right side of the third accommodation cavity <NUM> are both open. The guide rails <NUM> are arranged at both of the top and the bottom of the first accommodation cavity <NUM>, respectively. Specifically, the guide rails <NUM> are mounted on the inner side of the first accommodation cavity <NUM> and arranged between the first housing <NUM> and the second housing <NUM>. The sliding blocks <NUM> are arranged at both of the top and the bottom of the second housing, respectively. The sliding block <NUM> at the top of the second housing <NUM> is configured to cooperate with the guide rail <NUM> at the top of the first accommodation cavity <NUM>, and the sliding block <NUM> at the bottom of the second housing <NUM> is configured to cooperate with the guide rail at the bottom of the first accommodation cavity <NUM>. In this way, each of the sliding blocks <NUM> is movable on the corresponding guide rail <NUM> along the x direction or along the direction opposite to the x direction, so as to drive the second housing <NUM> to move away from or move towards the first housing <NUM>. The first limiting component <NUM> is disposed at the starting position of each of the guide rails <NUM>, and the second limiting component <NUM> is disposed at the end position of each of the guide rails <NUM>. In some embodiments of the disclosure, the guide rails <NUM> and the sliding blocks <NUM> are arranged on the housing <NUM>, so that the sliding blocks <NUM> may be moved relative to the guide rails <NUM> thereby enabling the first housing <NUM> and the second housing <NUM> to be moved relative to each other. In addition, the limiting components are arranged on the guide rails <NUM> to limit the positions of the sliding blocks <NUM>, and the sliding blocks <NUM> may be fixed relative to the respective limiting components when the sliding blocks are not subject to an external force. In this way, when no external force is applied, the second housing <NUM> and the first housing <NUM> may be limited to be relatively fixedly disposed at positions of the accommodated state or positions of the expanded state, so as to enable the display screen <NUM> to be stably fixed in the accommodated state or the expanded state correspondingly. Further, in some other embodiments, the limiting components may be mounted on the guide rails <NUM> at positions other than the starting position and the ending position, so that the second housing <NUM> and the first housing <NUM> may be limited to be relatively fixed disposed at particular positions, so as to enable the display screen <NUM> to be stably fixed at a particular position.

When the cooperation state of the first housing <NUM> and the second housing <NUM> is the accommodated state, the second side <NUM> of the first housing <NUM> and a left edge of the second housing <NUM> fit together, the second housing <NUM> cannot move towards the first housing <NUM> any more, while a volume of the third accommodation cavity <NUM> is zero. When the cooperation state of the first housing <NUM> and the second housing <NUM> is the partially expanded state, there is a distance between the second side <NUM> of the first housing <NUM> and the left side of the second housing <NUM>, while a volume of the third accommodation cavity <NUM> is greater than zero. When the cooperation state of the first housing <NUM> and the second housing <NUM> is the expanded state, the distance between the second side <NUM> of the first housing <NUM> and the left edge of the second housing <NUM> reaches the maximum distance in the process of drawing out the display screen <NUM>, while a volume of the third accommodation cavity <NUM> reaches the maximum in the stretching process of the display screen <NUM>.

When the display screen <NUM> is in the accommodated state, the cooperation state of the first housing <NUM> and the second housing <NUM> is the corresponding accommodated state, that is, the sliding blocks <NUM> at the top and bottom of the first housing cavity <NUM> are respectively snapped into the first limiting components <NUM> of the guide rails <NUM>, and the sliding blocks <NUM> is located at the starting position of the respective guide rails <NUM>. When the display screen <NUM> is in the expanded state, the cooperation state of the first housing <NUM> and the second housing <NUM> is the corresponding expanded state, that is, the sliding blocks <NUM> at the top and bottom of the first housing cavity <NUM> are respectively snapped into the second limiting components <NUM> of the guide rails <NUM>, and the sliding blocks <NUM> is located at the ending position of the respective guide rails <NUM>. When the sliding blocks <NUM> are located at the ending positions of the guide rails, the second housing <NUM> is located at an extreme position of movement of the second housing <NUM> away from the first housing <NUM>. In other words, when located at the extreme position, the second housing <NUM> cannot move away from the first housing <NUM> any more. When the display screen <NUM> is in the partially expanded state, the cooperation state of the first housing <NUM> and the second housing <NUM> is the corresponding partially expanded state, that is, each of the sliding blocks <NUM> at the top and bottom of the first housing cavity <NUM> is located at a position between the first limiting component <NUM> and the second limiting component <NUM> of the corresponding guide rail <NUM>, and each of the sliding blocks <NUM> is located at a middle position of the corresponding guide rail <NUM>. In the illustrated embodiments of the disclosure, the electronic device <NUM> is provided with the first housing <NUM> and the second housing <NUM>, and the guide rails <NUM> with the limiting components are disposed on the first housing <NUM>, the sliding blocks <NUM> are disposed on the second housing <NUM>, so as to enable the cooperation state of the first housing <NUM> and the second housing <NUM> to be switched between the accommodated state, the partially expanded state, and the expanded state, so that the display screen <NUM> is switched between the accommodated state, the partially expanded state, and the expanded state to realize the function of drawing the display screen <NUM> into or out of the housing <NUM>.

Referring to <FIG>, in some embodiments, the first lens component <NUM> and the reflective element <NUM> may be disposed in the first housing <NUM>. The image sensor <NUM> may be accommodated in the second housing <NUM> and fixed relative to the second housing <NUM>, and the image sensor <NUM> moves synchronously with the display screen <NUM> as the display screen <NUM> is drawn out of the housing <NUM>. That is, the first lens component <NUM> and the reflective element <NUM> are fixed relative to the first housing <NUM>, and the image sensor <NUM> is fixed relative to the second housing <NUM> and the second end of the display screen <NUM>. When the second housing <NUM> is expanded relative to the first housing <NUM>, the second housing <NUM> drives the second end of the display screen <NUM> and the image sensor <NUM> to move together along the direction in which the display screen <NUM> is drawn out, that is, the x direction illustrated in <FIG>. The reflective element <NUM> and the first lens component <NUM> are arranged in the first housing <NUM>, and the first housing <NUM> may have a larger accommodation cavity than the second housing <NUM>, which is conducive to accommodating the first lens component <NUM> which has a long length in a direction of the optical axis.

In some other embodiments, the image sensor <NUM> may be disposed in the first housing <NUM>. The first lens component <NUM> and the reflective element <NUM> may be accommodated in the second housing <NUM> and fixed relative to the second housing <NUM>, and the first lens component <NUM> and the reflective element <NUM> are configured to move synchronously with the display screen <NUM> being drawn into or out of the housing. In other words, the image sensor <NUM> is fixed relative to the first housing <NUM>, and the first lens component <NUM> and the reflective element <NUM> are fixed relative to the second housing <NUM> and the second end of the display screen <NUM>. When the second housing <NUM> is expanded relative to the first housing <NUM>, the second housing <NUM> is configured to drive the second end of the display screen <NUM>, the first lens component <NUM> and the reflective element <NUM> to move together along the direction in which the display screen <NUM> is drawn out. The image sensor <NUM> is arranged in the first housing <NUM>, and the first housing <NUM> may have a larger accommodation cavity relative to the second housing <NUM>. By arranging the mainboard of the electronic device <NUM> in the first accommodation cavity of the first housing <NUM>, a transmission distance of transmitting image data from the image sensor <NUM> to the mainboard can be reduced, a transmission speed can be increased, and transmission stability can be improved, which is beneficial for increasing a processing speed of the electronic device <NUM> and improving quality of a final image obtained by the electronic device <NUM>.

The camera module <NUM> may be disposed below the display screen <NUM>, and the light entrance of the camera module <NUM> may be arranged to face the display screen <NUM> or face away from the display screen <NUM>.

In some embodiments, referring to <FIG> and <FIG>, the light entrance of the camera module <NUM> is arranged to face away from the display screen <NUM>. A position of the rear surface (hereinafter referred to as the surface opposite to the display screen <NUM>) of the first housing <NUM> corresponding to the light entrance of the camera module <NUM> is provided with a first opening <NUM>, and a position of the rear surface (hereinafter referred to as the surface opposite to the display screen <NUM>) of the second housing <NUM> corresponding to the light entrance of the camera module <NUM> is provided with a second opening <NUM>. When the first housing <NUM> and the second housing <NUM> are in the accommodated state, the first opening <NUM> coincides with the second opening <NUM>, as illustrated in <FIG>. In this case, the camera module <NUM> is used as a rear camera of the electronic device <NUM>.

In some embodiments, referring to <FIG> and <FIG>, the light entrance of the camera module <NUM> is arranged to face the display screen <NUM>. A position of the upper surface (hereinafter referred to the front surface, i.e., the surface facing a z direction in <FIG> and <FIG>) of the first housing <NUM> corresponding to the light entrance of the camera module <NUM> is provided with a first opening <NUM>. In this way, the camera module <NUM> is used as a front camera of the electronic device <NUM>.

In some embodiments, referring to <FIG>, the light entrance of the camera module <NUM> is arranged to face the display screen <NUM>. Ambient light travels through the display screen <NUM> to reach the camera module <NUM> for imaging. In this case, the camera module <NUM> is used as an under-screen front camera of the electronic device <NUM>.

In some embodiments, the display screen <NUM> is switched between the expanded state and the accommodated state, and the camera module <NUM> is switched between the first mode and the second mode correspondingly. The camera module <NUM> corresponds to the first mode when the display screen <NUM> is in the accommodated state; the camera module <NUM> corresponds to the second mode when the display screen <NUM> is in the expanded state. Specifically, the first mode may include the short focal length mode. With respect to the short focal length mode, the camera module <NUM> has a short focal length, while a distance between the first lens component <NUM> and the image sensor <NUM> is short. The second mode may include the long focal length mode. With respect to the long focal length mode, the camera module <NUM> has a long focal length, while a distance between the first lens component <NUM> and the image sensor <NUM> is long. Due to the distance between the first lens component <NUM> and the image sensor <NUM> in the short focal length mode is relatively short, it is helpful for length matching between the camera module <NUM> in the short focal length mode and the housing in the accommodated state; due to the distance between the first lens component <NUM> and the image sensor <NUM> in the long focal length mode is relatively long, it is helpful for length matching between the camera module <NUM> in the long focal length mode and the housing in the expanded state. In the illustrated embodiments of the disclosure, the camera module <NUM> may be in the short focal length mode when the electronic device <NUM> is in the accommodated state, and the camera module <NUM> may be in the long focal length mode when the electronic device <NUM> is in the expanded state. In this way, the length in the lateral direction (i.e., the x direction) of the housing <NUM> of the electronic device <NUM> in the accommodated state or the expanded state may be well matched with the distance between the first lens component <NUM> and the image sensor <NUM>, so as to realize the accommodation and the expansion of the display screen <NUM> and the housing <NUM> of the electronic device <NUM>, as well as enabling the camera module <NUM> to be switched between the long focal length and the short focal length.

In addition, in the illustrated embodiments of disclosure, the electronic device <NUM> is configured with the display screen <NUM> and the housing <NUM> that are switched between the accommodated state and the expanded state, so that the lateral length of the housing <NUM> may be switched according to the requirements of specific usage scenarios, which is conductive for the miniaturization of the product. Meanwhile, the display screen <NUM> and the housing <NUM> may be expanded in response to requiring a long focal length camera, thereby increasing the lateral length of the electronic device <NUM> and enabling the electronic device <NUM> to accommodate the long focal length camera and the sensor arranged in the long focal length mode. Furthermore, the electronic device <NUM> may be switched to the accommodated state for portability.

Referring to <FIG>, in some embodiments, when the display screen is in the accommodated state as illustrated in <FIG>, there is the first distance between the first lens component <NUM> and the image sensor <NUM>, while the camera module <NUM> is in the short focal length state of the first mode. When the display screen <NUM> is in the expanded state, as illustrated in <FIG>, there is the second distance between the first lens component <NUM> and the image sensor <NUM>, the second distance is greater than the first distance, while the camera module <NUM> is in the long focal length state of the second mode.

In some embodiments, as illustrated in <FIG>, when the display screen <NUM> is partially expanded, i.e., the display screen <NUM> is in the partially expanded state, the distance between the first lens component <NUM> and the image sensor <NUM> is greater than the first distance and less than the second distance. The light is reflected by the reflective element 10to travel through the first lens component <NUM> to thereby reach the image sensor <NUM> for imaging.

In some embodiments, referring to <FIG>, the first lens component <NUM> has the first optical axis O, and the second lens component <NUM> has the second optical axis O'. When the display screen is in the accommodated state, as illustrated in <FIG>, the first optical axis O and the second optical axis O' are parallel and separated from each other, the second lens component <NUM> is located outside of the optical path between the first lens component <NUM> and the image sensor <NUM>, and the camera module <NUM> is in the short focal length mode. When the display screen is in the expanded state, as illustrated in <FIG>, the first optical axis O coincides with the second optical axis O', the second lens component <NUM> is located in the optical path between the first lens component <NUM> and the image sensor <NUM>, and the camera module <NUM> is in the long focal length mode. Specifically, the first optical axis O may be in the same direction as the display screen <NUM> is drawn out. In some embodiments corresponding to <FIG>, the direction in which the display screen <NUM> is drawn into or out of the housing <NUM> and the direction of the first optical axis O may be the lateral direction (also referred to as the width direction) of the electronic device <NUM>, i.e., the x direction illustrated in <FIG>. In some other embodiments, the direction in which the display screen <NUM> is drawn into and out of the housing <NUM> and the direction of the first optical axis O may be the vertical direction of the electronic device <NUM>, i.e., the y direction illustrated in <FIG>.

In some embodiments, referring to <FIG>, during the switching of the display screen <NUM> from the accommodated state to the expanded state, the image sensor <NUM> is configured to move synchronously with the display screen <NUM> as the display screen <NUM> being drawn out of the housing <NUM>.

In some embodiments, the second lens component <NUM> is configured to move towards a position between the first lens component <NUM> and the image sensor <NUM>, in response to a distance between the first lens component <NUM> and the image sensor <NUM> being greater than a preset threshold. When the distance between the first lens component <NUM> and the image sensor <NUM> is a predetermined threshold, a space defined by the first lens component <NUM> and the image sensor <NUM> is exactly enough for accommodating the second lens component <NUM>. That is, in response to the space defined by the first lens component <NUM> and the image sensor <NUM> being exactly enough for accommodating the second lens component <NUM>, the second lens component <NUM> is configured to move towards a position between the first lens component <NUM> and the image sensor <NUM>, thereby preventing the component from being damaged by collision during the movement.

In some other embodiments, the second lens component <NUM> is configured to move towards a position between the first lens component <NUM> and the image sensor <NUM>, in response to the display screen <NUM> being drawn out. As such, the time required to switch from the short focal length to the long focal length may be reduced, the shooting speed is increased, and the user experience is improved.

When the display screen <NUM> and the housing <NUM> are in the accommodated state, the second lens component <NUM> is accommodated in the first accommodation cavity <NUM> of the first housing <NUM>, or be accommodated in the second accommodation cavity <NUM> of the second housing <NUM>.

In some embodiments, the second lens component <NUM> may be configured to move towards the position between the first lens component <NUM> and the image sensor <NUM> by performing two translations. Specially, the second lens component <NUM> is configured to firstly translate a distance along the second optical axis O', and then translate a distance towards the direction of the first optical axis O. As illustrated in <FIG> and <FIG>, the second lens component <NUM> in <FIG> may be configured to firstly translate a distance towards the x direction, and then translate a distance towards the y direction, i.e., the direction of the first optical axis O, thereby reaching the position of the second lens component <NUM> illustrated in <FIG>.

In some other embodiments, the movement in which the second lens component <NUM> moves towards the position between the first lens component <NUM> and the image sensor <NUM> may include a rotation. For example, the second lens component <NUM> at the position illustrated in <FIG> is configured to be rotated counterclockwise around a fixed point P by <NUM>° to thereby enable the second optical axis O' to coincide with the first optical axis O after the rotation. The fixed point P may locate on the first optical axis O. After the rotation, the second lens component <NUM> is further configured to translate a distance towards the first lens component <NUM> or the image sensor <NUM>. In the illustrated embodiments of the disclosure, by rotating the second lens component <NUM>, the second optical axis O' of the second lens component <NUM> is enabled to coincide with the first optical axis O of the first lens component <NUM>, so that the second lens component <NUM> cooperate with the first lens component <NUM> for imaging.

In some embodiments, the electronic device <NUM> further includes the first focal length adjusting component <NUM> and the second focal length adjusting component <NUM>. Specifically, the first focal length adjusting component <NUM> is connected with the first lens component <NUM> and configured to adjust the focal length and the position of the first lens component <NUM>, so as to enable the light traveling through the first lens component <NUM> to be focused on the image sensor <NUM> in the first mode. Alternatively, the second focal length adjusting component <NUM> is connected with the second lens component <NUM> and configured to adjust the focal length and the position of the second lens component <NUM>, so as to enable the light to travel through the first lens component <NUM> and the second lens component <NUM> to be focused on the image sensor <NUM> in the second mode. Still alternatively, the first focal length adjusting component <NUM> is connected with the first lens component <NUM>, and the first focal length adjusting component <NUM> is configured to adjust the focal length and the position of the first lens component <NUM> to thereby enable the light traveling through the first lens component <NUM> to be focused on the image sensor <NUM> in the first mode; and the second focal length adjusting component <NUM> is connected with the second lens component <NUM>, and the second focal length adjusting component <NUM> is configured to adjust a focal length and the position of the second lens component <NUM> to thereby enable the light traveling through the first lens component <NUM> and the second lens component <NUM> to be focused on the image sensor <NUM> in the second mode. Yet alternatively, the first focal length adjusting component <NUM> is connected with the first lens component <NUM> and is configured to adjust a focal length of the first lens component <NUM>, the second focal length adjusting component <NUM> is connected with the second lens component <NUM> and is configured to adjust a focal length of the second lens component <NUM>, so as to enable the light traveling through the first lens component <NUM> and the second lens component <NUM> to be focused on the image sensor <NUM> for imaging when the camera module <NUM> is in other states.

When the display screen <NUM> and the housing <NUM> are in the accommodated state, there is the first distance between the first lens component <NUM> and the image sensor <NUM>, while the camera module <NUM> is in the first mode. In addition, when the camera module <NUM> is in the short focal length state, the first focal length adjusting component <NUM> may be connected with the first lens component <NUM> and configured to adjust the focal length and the position of the first lens component <NUM>, thereby enabling the camera module <NUM> in the short focal length state to focus the light traveling through the first lens component <NUM> on the image sensor <NUM> for imaging.

When the display screen <NUM> and the housing <NUM> are in the expanded state, there is the second distance between the first lens component <NUM> and the image sensor <NUM>, while the camera module <NUM> is in the second mode. In addition, when the camera module <NUM> is in the long focal length state, the first focal length adjusting component <NUM> may be connected with the first lens component <NUM> and configured to adjust the focal length and the position of the first lens component <NUM>, the second focal length adjusting component <NUM> may be connected with the second lens component <NUM> and configured to adjust the focal length and the position of the second focal length adjusting component <NUM> to thereby enable the camera module <NUM> in the long focal length state to focus the light traveling through the first lens component <NUM> and the second lens component <NUM> on the image sensor <NUM> for imaging.

When the display screen <NUM> and the housing <NUM> are expanded partially, that is, when the display screen <NUM> and the housing <NUM> are in the partially expanded state, the distance between the first lens component <NUM> and the image sensor <NUM> is greater than the first distance and less than the second distance. In this case, the camera module <NUM> is in a third mode where the camera module <NUM> may be in a zoom state. The first focal length adjusting component <NUM> may be connected with the first lens component <NUM> and configured to adjust the focal length and the position of the first lens component <NUM>, the second focal length adjusting component <NUM> may be connected with the second lens component <NUM> and configured to adjust the focal length and position of the second lens component <NUM>, so as to enable the camera module <NUM> in the zoom state of the third mode to focus the light traveling through the first lens component <NUM> and the second lens component <NUM> on the image sensor <NUM> for imaging.

Specifically, the focal length adjusting component may be implemented as the electrostatic actuator component, the electromagnetic actuator component, the magnetostrictive actuator component, the piezoelectric actuator component, the piezoelectric motor, the stepping motor, or the electroactive polymer actuator motor. By providing the focal length adjustment component in the illustrated embodiments of the disclosure, the display screen <NUM> and the housing <NUM> are enabled to be in different states. In addition, the focal length adjustment component may be configured to adjust the focal length and the position of the lens component to focus the light traveling through the lens component on the image sensor <NUM> for imaging when there are different distances between the first lens component <NUM> and the image sensor <NUM>.

In some embodiments, the first lens component <NUM> includes one or more lens groups, the second lens component <NUM> includes one or more lens groups. Each lens group of the one or more lens groups includes one or more lenses. In the above specification of the disclosure, it is described by taking the first lens component <NUM> including one lens group and the second lens component <NUM> including one lens group as an example. It can be understood that, corresponding embodiments may be implemented in a similar manner in any of the cases where the first lens component <NUM> includes multiple lens groups, the second lens component includes multiple lens groups, or both the first lens component <NUM> and the second lens component <NUM> include multiple lens groups. The related description in <FIG>, <FIG>, <FIG>, and <FIG> that the second lens component <NUM> includes one lens group is just an example useful for understanding the ienvnetion but is outside the scope of the ienvnetion as filed.

In some embodiments, the second lens component <NUM> includes multiple lens groups, and the multiple lens groups may be movable to a position between the first lens component <NUM> and the image sensor <NUM> asynchronously. Specifically, the second lens component <NUM> includes a first lens group <NUM> and a second lens group <NUM>. Alternatively, the second lens component <NUM> includes the first lens group <NUM>, the second lens group <NUM> and a third lens group. Still alternatively, the second lens component <NUM> includes the first lens group <NUM>, the second lens group <NUM>, the third lens group, and a fourth lens group. The quantity of the lens groups in the second lens component <NUM> is not limited to the illustrated embodiments of the disclosure. It is illustrated as follows by taking the second lens component <NUM> including the first lens group <NUM> and the second lens group <NUM> as illustration.

Referring to <FIG>, <FIG> and <FIG>, the second lens component includes the first lens group <NUM> and the second lens group <NUM>. As illustrated in <FIG>, when the display screen <NUM> and the housing <NUM> are in the accommodated state, the first lens component <NUM> and the second lens component <NUM> locate in the first accommodation cavity <NUM> with the first optical axis O not being coincident with the second optical axis O'. As illustrated in <FIG>, when the display screen <NUM> and the housing <NUM> are in the partially expanded state and the distance between the first lens component <NUM> and the image sensor <NUM> is enough to accommodate the first lens group <NUM>, the first lens group <NUM> first is configured to be rotated and translated to thereby move into the third accommodation cavity <NUM>, so as to arrange the first lens group <NUM> on the first optical axis O. In addition, after the positions and focal lengths of the first lens group <NUM> and the first lens group <NUM> are adjusted by the first focal length adjusting component <NUM> and the second focal length adjusting component <NUM>, the first lens component <NUM> and the first lens group <NUM> cooperate to converge the light at the image sensor <NUM> for imaging. As illustrated in <FIG>, when the display screen <NUM> and the housing <NUM> are in the expanded state, or the distance between the first lens group <NUM> and the image sensor <NUM> is enough to accommodate the second lens group <NUM>, on the basis of <FIG>, the second lens group <NUM> is configured to move into the third accommodation cavity <NUM> by rotating and translating, so as to enable the second lens group <NUM> to be also located on the first optical axis O with the second optical axis O' being coincident with the first optical axis O. In addition, after the positions and focal lengths of the first lens component <NUM>, the first lens group <NUM>, and the second lens group <NUM> are adjusted by the first focal length adjusting component <NUM> and the second focal length adjusting component <NUM>, the first lens component <NUM>, the first lens group <NUM>, and the second lens group <NUM> are configured to cooperate to converge the light at the image sensor <NUM> for imaging. In some other embodiments, when the display screen is pulled out of or into the housing <NUM>, the first lens group <NUM> and the second lens group <NUM> are configured to be rotated and translated to move into the third accommodation cavity <NUM> simultaneously, thereby enabling both of the first lens group <NUM> and the second lens group <NUM> to be located on the first optical lens O, that is, the second optical axis O' coincides with the first optical axis O. In addition, after the positions and focal lengths of the first lens component <NUM>, the first lens group <NUM>, and the second lens group <NUM> are adjusted by the first focal length adjusting component <NUM> and the second focal length adjusting component <NUM>, the first lens component <NUM>, the first lens group <NUM>, and the second lens group <NUM> cooperate to converge the light into the image sensor <NUM> for imaging.

In some embodiments, referring to <FIG>, the electronic device <NUM> further includes a force sensor mounted on the first housing <NUM> and the second housing <NUM>, a reel motor (not illustrated in the drawings) that works in cooperation with the reel <NUM>, and a driver (not illustrated in the drawings) that may drive the moving of the sliding block <NUM> at the top and bottom of the second housing <NUM>. When a drawing force in the direction of pulling out the display screen <NUM>, i.e., the x direction, sensed by the force sensor is greater than a preset value, the reel motor may be configured to drive the reel <NUM> to rotate to release the display screen <NUM>, so that the display screen <NUM> is enabled to be expanded out of the housing <NUM>, and the second end of the display screen <NUM> is configured to move towards the x direction. At the same time, the driver drives the sliding blocks <NUM> are configured to move to thereby drive the second housing <NUM> to move along the x direction to reach a preset position. In this way, both of the display screen <NUM> and the housing <NUM> can be enabled to be expanded at the same time. When a drawing force in a direction opposite to the direction of drawing out the display screen <NUM>, i.e., a direction opposite to the x direction, sensed by the force sensor is greater than a preset value, the reel motor may be configured to drive the reel <NUM> to rotate to accommodate the display screen <NUM> in the housing and to wind the display screen <NUM> around the reel <NUM>, and the second end of the display screen <NUM> is configured to move towards the direction opposite to the x direction. At the same time, the driver is configured to drive the sliding blocks <NUM> to move to thereby drive the second housing <NUM> to move, along the direction opposite to x direction, to reach a preset position. In this way, both of the display screen <NUM> and the housing <NUM> can be enabled to be accommodated at the same time.

In addition, the camera module <NUM> includes the reflective element <NUM> and the lens component which are adjusted to be in the first operating mode or the second operating mode, so that the electronic device <NUM> is enabled with the display screen <NUM> having the large area in the expanded state and the display screen <NUM> having the small area and the short lateral length in the accommodated state. In this way, the electronic device <NUM> can be used in various application scenarios, it is conductive for meeting the user's diversified usage requirements for the electronic device <NUM>, as well as enabling the electronic device <NUM> with a short lateral length in the first operating mode, which is beneficial to the miniaturization of the electronic device <NUM> in the accommodated state, and improves the portability of the electronic device <NUM> of the disclosure.
