Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of electronic products, and in particular, to a lifting mechanism, a camera module, and an electronic device. BACKGROUND

[0002] With the rapid development of technology, electronic devices such as mobile phones and tablet computers have become an indispensable part of people's lives. In particular, electronic devices with camera functions are widely favored by users. With the continuous change of people's living needs, people's requirements for the functions and performance of cameras are becoming higher and higher. In order to improve the performance of the camera and make the function of the camera more powerful, the volume of the camera needs to be made larger, which will cause the appearance of the electronic device to be severely protruding and easy to be damaged. SUMMARY

[0003] Embodiments of the present application provide a lifting mechanism, a camera module, and an electronic device, which are used to improve the phenomenon that the volume of the camera in the electronic device is large, causing the appearance of the electronic device to be severely protruding and easy to be damaged.

[0004] To achieve the above-mentioned purpose, embodiments of the present application provide the following solutions:

[0005] On the one hand, a lifting mechanism is provided, which includes a base, a lifting piece, and a first driving assembly. The base includes opposite first and second surfaces, and the direction from the first surface to the second surface is a pop-out direction. The lifting piece is arranged along the pop-out direction with the base, and the lifting piece is slidingly connected with the base along the pop-out direction. The lifting piece includes a first driving sliding groove, and the extension direction of the first driving sliding groove intersects the pop-out direction. The first driving assembly is installed on the base, and the first driving assembly includes a first driving piece and a first swing piece. The first end of the first swing piece is connected with the first driving piece, and the second end of the first swing piece is slidingly connected with the first driving sliding groove.

[0006] When the lifting mechanism is in a retracted state, the distance between the lifting piece and the first surface in the pop-out direction is a first distance. In the process of switching the lifting mechanism from the retracted state to a pop-out state, the first swing piece moves toward the pop-out direction through the first driving piece. When the lifting mechanism is in the pop-out state, the distance between the lifting piece and the first surface in the pop-out direction is a second distance, and the second distance is greater than the first distance.

[0007] By the above arrangement, when the lifting mechanism is in the retracted state, the distance between the lifting member and the first surface is small, so that at least part of the camera module can be retracted into the accommodating cavity, thereby avoiding damage to the camera module. During the process of switching the lifting mechanism from the retracted state to the ejected state, the first swing member moves towards the ejection direction by the first driving member, wherein the movement of the second end of the first swing member can be decomposed into two parts, one part is the movement component in the extension direction of the first driving sliding groove, which can make the second end of the first swing member slide in the first driving sliding groove; the other part is the movement component in the ejection direction, which can make the first swing member drive the lifting member to move along the ejection direction and increase the distance between the lifting member and the first surface. When the lifting mechanism is in the ejected state, at least part of the camera module can be extended from the accommodating cavity to increase the optical available space of the camera module to achieve high-quality shooting.

[0008] In some embodiments, when the lifting mechanism is in the ejected state, the direction from the first end of the first swing member to the second end of the first swing member is parallel to the ejection direction. By the above arrangement, when the lifting mechanism is in the ejected state and subjected to impact such as falling or pressing, the impact force received by the lifting member can be prevented from being transmitted to the first driving member through the first swing member, thereby facilitating the protection of the first driving member and improving the reliability of the first driving member.

[0009] In some embodiments, when the lifting mechanism is in the ejected state, in the extension direction of the first driving sliding groove, the second end of the first swing member is in contact with the side wall of the first driving sliding groove. By the above arrangement, the side wall of the first driving sliding groove can be used to block the continuous movement of the second end of the first swing member, thereby facilitating the guarantee that the direction from the first end of the first swing member to the second end of the first swing member is parallel to the ejection direction, and facilitating the guarantee of strong support of the lifting member by the first swing member, thereby further guaranteeing the reliability of the first driving member.

[0010] In some embodiments, when the lifting mechanism is in the retracted state, in the ejection direction, the distance between the second end of the first swing member and the first surface is a third distance; when the lifting mechanism is in the ejected state, in the ejection direction, the distance between the second end of the first swing member and the first surface is a fourth distance, and the fourth distance is greater than the third distance. By the above arrangement, during the conversion of the lifting mechanism from the retracted state to the ejected state, the second end of the first swing member rotates relative to the first end of the first swing member away from the first surface, so as to increase the distance between the second end of the first swing member and the first surface.

[0011] In some embodiments, the extension direction of the driving sliding groove is parallel to the first direction, the rotation axis of the first swing member is parallel to the second direction, the second direction is perpendicular to the first direction, and the ejection direction is perpendicular to the plane in which the first direction and the second direction lie. Through the above arrangement, it is beneficial to avoid the second end of the first swing member from being stuck when sliding in the first driving sliding groove.

[0012] In some embodiments, the distance between the first end of the first swing member and the second end of the first swing member is less than the size of the first driving sliding groove in the first direction. Through the above arrangement, during the conversion of the lifting mechanism from the retracted state to the ejected state, the second end of the first swing member rotates at a smaller angle relative to the first end of the first swing member, thereby reducing the movement component of the second end of the first swing member in the ejection direction, resulting in a smaller distance of the first swing member moving the lifting member in the ejection direction.

[0013] In some embodiments, when the lifting mechanism is in the retracted state, in the ejection direction, the distance between the first end of the first swing member and the first surface is greater than the distance between the second end of the first swing member and the first surface, and in the first direction, the second end of the first swing member does not contact the side wall of the driving sliding groove. Through the above arrangement, during the conversion of the lifting mechanism from the retracted state to the ejected state, the second end of the first swing member needs to rotate an angle greater than 90° relative to the first end of the first swing member. Compared with the embodiment in which the first swing member rotates a smaller angle to achieve the conversion from the retracted state to the ejected state (for example, the second end of the first swing member rotates less than 90° relative to the first end of the first swing member), in the present embodiment, the size of the first end of the first swing member pointing to the second end of the second swing member can be reduced, thereby facilitating the reduction of the occupied space of the first driving assembly.

[0014] In some embodiments, the first driving member includes a driving motor, and an output shaft of the driving motor is connected to the first end of the first swing member. Through the above arrangement, during the conversion of the lifting mechanism from the retracted state to the ejected state, the output shaft of the driving motor can drive the first swing member to rotate.

[0015] In some embodiments, the first driving member further includes a speed reducer, an output shaft of the driving motor is connected to an input shaft of the speed reducer, an output shaft of the speed reducer is connected to the first end of the first swing member, and the first swing member and the driving motor are located on the same side of the speed reducer. Through the above arrangement, the speed reducer can reduce the rotation speed of the first swing member while transmitting power to meet the lifting rate requirement of the camera module. Since the first swing member and the driving motor are located on the same side of the speed reducer, it is beneficial to improve the compactness of the layout of the first driving member and reduce the occupied space of the first driving member.

[0016] In some embodiments, the lifting member further comprises a second driving slot, the second driving slot is arranged in the second direction and spaced apart from the first driving slot, and an extension direction of the second driving slot intersects the ejection direction. The lifting mechanism further comprises a second driving assembly, the second driving assembly is mounted on the base, the second driving assembly and the first driving assembly are arranged in the second direction, the second driving assembly comprises a second driving member and a second swing member, a first end of the second swing member is connected with the second driving member, and a second end of the second swing member is slidably connected with the second driving slot. In the process of switching from the retracted state to the ejected state, the second swing member is rotated towards the ejection direction by the second driving member. Through the above arrangement, in the process of switching from the retracted state to the ejected state, the second swing member is moved towards the ejection direction by the second driving member, so that at least part of the camera module can be extended from the accommodating cavity to improve the optical available space of the camera module and achieve high-quality shooting.

[0017] In some embodiments, the first driving assembly and the second driving assembly are arranged symmetrically about the center of the lifting member. Through the above arrangement, in the process of switching from the retracted state to the ejected state, the driving force of the first driving assembly and the driving force of the second driving assembly acting on the lifting member can also be arranged symmetrically about the center, so that the lifting member is uniformly stressed, which is beneficial to improve the smoothness of the movement of the lifting member in the ejection direction.

[0018] In some embodiments, the lifting mechanism comprises a first sliding rail, a rolling body and a second sliding rail, the first sliding rail is connected with the base, the second sliding rail is connected with the lifting member, the first sliding rail has a first sliding slot, the second sliding rail has a second sliding slot, and the extension directions of the first sliding slot and the second sliding slot are parallel to the ejection direction, and the rolling body is arranged to roll between the first sliding slot and the second sliding slot. Through the above arrangement, the rolling body can roll between the first sliding slot and the second sliding slot, so that the first sliding rail can move relative to the second sliding rail, and the first sliding rail and the second sliding rail can play a guiding role, so that the lifting member and the base can move relative to each other through the first sliding rail and the second sliding rail, which is beneficial to ensure the smoothness of the movement between the lifting member and the base.

[0019] In some embodiments, the number of rolling bodies is a plurality, the plurality of rolling bodies are arranged in the ejection direction, and the lifting mechanism further comprises a retainer, the retainer is located between the first sliding slot and the second sliding slot, the retainer comprises a plurality of mounting holes arranged in the ejection direction, and one rolling body is mounted in one mounting hole. By arranging a plurality of rolling bodies, it is beneficial to further reduce the friction of the second sliding rail relative to the first sliding rail, and to further improve the smoothness of the movement between the lifting member and the base.

[0020] In some embodiments, the first slide rail comprises a first stop plate and a second stop plate arranged along the ejection direction, the distance between the first stop plate and the first surface is greater than the distance between the second stop plate and the first surface in the ejection direction; when the lifting mechanism is in the retracted state, the second slide rail is in contact with the second stop plate; when the lifting mechanism is in the ejected state, the second slide rail is in contact with the first stop plate. Through the above arrangement, the first stop plate and the second stop plate can both play a limiting role.

[0021] In some embodiments, the lifting mechanism further comprises a structural member and an elastic body, the structural member is in sliding connection with the lifting member along the ejection direction, and the elastic body is arranged between the lifting member and the structural member along the ejection direction. When the lifting mechanism is in the ejected state and the lifting mechanism is subjected to external impact, the structural member moves towards the lifting member under the action of the external impact force, so that the elastic body is in a compressed state. At this time, since the elastic body can absorb part of the external impact force, it is beneficial to avoid the transmission of the external impact force to the lifting member, and then to the first driving member or the second driving member through the first swing member or the second swing member, thereby benefiting the protection of the first driving member or the second driving member and improving the reliability of the first driving member or the second driving member.

[0022] In some embodiments, the structural member comprises a first guide column, the lifting member comprises a second guide column, and the elastic body is sleeved on the first guide column and the second guide column. Through the above arrangement, the first guide column and the second guide column can play a guiding effect on the elastic body.

[0023] On the other hand, the embodiments of the present application provide a camera module, comprising a lens assembly and the lifting mechanism in any of the above embodiments, and the lifting mechanism is sleeved outside the lens assembly.

[0024] The camera module provided by the embodiments of the present application comprises the lifting mechanism as described above, and therefore has all the beneficial effects as described above, which will not be repeated here.

[0025] On the other hand, the embodiments of the present application provide an electronic device, comprising a shell and the camera module in the above embodiments, and the camera module is arranged on the shell.

[0026] In some embodiments, the shell encloses a receiving cavity. When the lifting mechanism in the camera module is in the retracted state, the lens assembly of the camera module is located inside the receiving cavity. During the process of switching the lifting mechanism in the camera module from the retracted state to the ejected state, the lens assembly of the camera module moves along the ejection direction. When the lifting mechanism in the camera module is in the ejected state, part of the lens assembly of the camera module is located outside the receiving cavity.

[0027] The electronic device provided by the embodiments of the present application comprises the camera module as described above, and therefore has all the beneficial effects as described above, which will not be repeated here. BRIEF DESCRIPTION OF DRAWINGS

[0054] The embodiments of the present application provide an electronic device, which can include a mobile phone, a tablet computer, a smart bracelet, a smart watch, etc. The embodiments of the present application do not limit the electronic device. The electronic device includes a camera module, and the camera module can realize functions such as photographing and video recording.

[0055] In the following, the electronic device will be taken as a mobile phone as an example for introduction. It can be understood that the electronic device in the embodiments of the present application is not limited to a mobile phone. Figure 1a An exploded view of the structure of an electronic device provided in the embodiments of the present application is provided. Please refer to Figure 1a , the electronic device 1 includes a housing 12 and a display panel 11, wherein the housing 12 can include a middle frame 13 and a back cover 14, the display panel 11 covers one side of the middle frame 13, the back cover 14 covers the other side of the middle frame 13, and the middle frame 13 and the back cover 14 can be surrounded to form a receiving cavity 15; the electronic device 1 further includes a battery 16 and a mainboard 17 arranged in the receiving cavity 15, the mainboard 17 and the battery 16 can be fixed on the middle frame 13, and the mainboard 17 is electrically connected with the battery 16 and the display panel 11.

[0056] In some embodiments, the camera module 2 can be a rear camera, and correspondingly, the camera module 2 can be arranged on the back cover 14 of the housing 12, and the camera module 2 can be electrically connected with the mainboard 17, so that the camera module 2 can be controlled by the mainboard 17 to perform photographing or video recording.

[0057] In the embodiments of the present application, the camera module 2 includes a lens assembly. The lens assembly includes a light-transmitting cover plate, an optical lens, and an optical sensor, which can be arranged along an optical axis. The optical sensor is located on the image side of the optical lens, and the light-transmitting cover plate is located on the object side of the optical lens. External light passes through the light-transmitting cover plate and the optical lens and is received by the optical sensor to form an image on the optical sensor. The optical sensor is electrically connected with Figure 1a the mainboard 17 as shown in the figure, so as to convert the received image into an electrical signal and send it to the mainboard 17, thereby realizing photographing or video recording.

[0058] Figure 1b A structural diagram of a camera module is provided for an embodiment of the present application. In the embodiment of the present application, referring to Figure 1b , the camera module 2 further comprises a lifting mechanism 200, which is sleeved on the lens assembly 21. When the lens assembly 21 performs lifting movement, the lifting mechanism 200 also performs lifting movement, thereby leaving a lifting space for the lens assembly 21.

[0059] In combination with Figure 1a and Figure 1b , when the lifting mechanism 200 in the camera module 2 is in the retracted state, at least part of the lens assembly 21 of the camera module 2 is located inside the accommodating cavity 15, wherein the part of the lens assembly 21 of the camera module 2 located inside the accommodating cavity 15 is a first part; in the process of switching from the retracted state to the popped-out state, the lens assembly 21 of the camera module 2 moves along a popping-out direction; when the lifting mechanism 200 in the camera module 2 is in the popped-out state, part of the lens assembly 21 of the camera module 2 is located outside the accommodating cavity 15, wherein the part of the lens assembly 21 of the camera module 2 located inside the accommodating cavity 15 is a second part, and in the popping-out direction, the size of the second part is smaller than the size of the first part. The popping-out direction can be perpendicular to the back cover.

[0060] In combination with Figure 1a and Figure 1b , the back cover 14 is provided with an opening 18, and the opening 18 and the accommodating cavity 15 are in communication. The popping-out direction can be the thickness direction of the back cover 14. When the lifting mechanism 200 is in the retracted state, at least part of the lens assembly 21 can be arranged opposite to the opening 18, and at least part of the lens assembly 21 is located inside the accommodating cavity 15. In the process of switching from the retracted state to the popped-out state, the lifting mechanism 200 can drive part of the lens assembly 21 to extend out of the accommodating cavity 15 through the opening 18. When the lifting mechanism 200 is in the popped-out state, at least part of the lens assembly 21 can be arranged opposite to the opening 18, and at least part of the lens assembly 21 is located outside the accommodating cavity 15.

[0061] Through the above arrangement, when the electronic device 1 is used for shooting, at least part of the camera module 2 extends out of the accommodating cavity 15 to improve the optical available space of the camera module 2, thereby realizing high-quality shooting; when shooting is not needed, at least part of the camera module 2 is retracted into the accommodating cavity 15 to avoid the camera module 2 protruding too much outside the shell to affect the appearance of the electronic device 1.

[0062] Figure 2 A structural diagram of the lifting mechanism 200 in the retracted state is provided for an embodiment of the present application; Figure 3 A structural diagram of the lifting mechanism 200 in the popped-out state is provided for an embodiment of the present application; Figure 4An exploded view of a lifting mechanism 200 provided in an embodiment of this application. See below for reference. Figure 2 , Figure 3 as well as Figure 4 The structure of the lifting mechanism 200 is described.

[0063] In this embodiment, the lifting mechanism 200 includes a base 210. The base 210 can be mounted on the rear cover 14, and the base 210 can be located on the side of the rear cover 14 closer to the display panel 11. For example, the lifting mechanism 200 may include a cover 220, and the cover 220 and the base 210 can be detachably connected so that the cover 220 and the base 210 together enclose an accommodating space N, at least a portion of which is located within the aforementioned accommodating cavity 15.

[0064] Figure 5 An exploded view of the structure of a base 210, a first drive assembly 250, and a lifting component 240 provided in an embodiment of this application; Figure 6 This is a structural diagram of a base 210 provided in an embodiment of this application. (In conjunction with...) Figure 5 and Figure 6 As shown, the base 210 may include a first surface 2101 and a second surface 2102 opposite to each other. Exemplarily, the base 210 may include a base plate 211 and a boss 212, wherein the lower surface of the base plate 211 can be the first surface 2101 of the base 210, the upper surface of the base plate 211 can be the second surface 2102 of the base 210, the boss 212 can be located on the upper surface of the base plate 211, and the boss 212 and the base plate 211 can be an integral structure. The base 210 may also have a first through hole 219 penetrating the boss 212 and the base plate 211, and the lens assembly 21 can be located within the first through hole 219 so that the base 210 is fitted onto the lens assembly 21. Of course, the structure of the base 210 is merely exemplary, and the specific structure of the base 210 is not limited in this application embodiment.

[0065] For example, in an embodiment where the base plate 211 is generally a rectangular flat plate, the direction from the first surface 2101 to the second surface 2102 can be the thickness direction of the base plate 211. For ease of explanation, the direction from the first surface 2101 to the second surface 2102 is defined as the ejection direction Z, the width direction of the base plate 211 is referred to as the first direction X, and the length direction of the base plate 211 is referred to as the second direction Y. The ejection direction Z is perpendicular to the plane containing the first direction X and the second direction Y.

[0066] Among them, combined Figure 4As shown, the cover 220 can be threadedly connected to the base plate 211 of the base 210, and the cover 220 can also be bonded to the inner wall of the rear cover 14 so that the lifting mechanism 200 is mounted on the rear cover 14. For example, the surface of the cover 220 facing away from the base 210 (e.g.) Figure 4 The upper surface of the middle cover 220 can be adhered to the inner wall of the rear cover 14. The cover 220 can be provided with a second through hole 229 corresponding to the first through hole 219, and the second through hole 229 also corresponds to the opening of the rear cover 14. During the process of the lifting mechanism 200 switching from the retracted state to the pop-out state, a part of the lens assembly 21 extends out of the accommodating space N through the second through hole 229, so that a part of the lens assembly 21 can extend out of the accommodating cavity 15 through the opening of the rear cover 14.

[0067] like Figure 5 As shown in the embodiment of this application, the lifting mechanism 200 further includes a lifting component 240 and a first drive assembly 250. Both the lifting component 240 and the first drive assembly 250 are mounted on the base 210. Figure 7 This is an exploded view of a lifting component and a structural component provided in an embodiment of this application. (Combined with...) Figure 5 and Figure 7 The structure of the lifting component 240 is described as shown.

[0068] In this embodiment, at least a portion of the lifting member 240 and the base 210 are arranged along the pop-out direction Z, and the lifting member 240 and the base 210 are slidably connected along the pop-out direction Z. The orthographic projection of the lifting member 240 on a plane perpendicular to the pop-out direction Z can overlap at least a portion of the orthographic projection of the base 210 on the same plane. For example, the lifting member 240 can be generally cylindrical, and can be fitted over the boss 212 of the base 210, and can be slidably connected to the boss 212 along the pop-out direction Z. For instance, the lifting member 240 and the boss 212 of the base 210 can be slidably connected via a groove and a slider. This embodiment does not specifically limit the slidable connection method between the lifting member 240 and the base 210. Through the above arrangement, the lifting member 240 can be slidably connected to the boss 212 of the base 210 along the pop-out direction Z, and the lifting member 240 can be arranged with the base plate 211 of the base 210 along the pop-out direction Z.

[0069] The lifting member 240 includes a first driving groove 249, the extension direction of which intersects the pop-out direction Z. For example, the first driving groove 249 may be located on the side surface of the lifting member 240 opposite to the boss 212. This application embodiment does not limit the specific shape of the first driving groove 249, as long as its extension direction intersects the pop-out direction Z.

[0070] Continue to refer toFigure 5 The first driving assembly 250 is installed on the base 210, and the first driving assembly 250 includes a first driving member 251 and a first swing member 252. A first end 2521 of the first swing member 252 is connected with the first driving member 251, and a second end 2522 of the first swing member is in sliding connection with the first driving sliding groove 249. For example, the first swing member 252 can have a rod structure, the first end 2521 of the first swing member 252 can have a first protruding column 252a connected with the first driving member 251, and the second end 2522 of the first swing member 252 can have a second protruding column 252b in sliding connection with the first driving sliding groove 249. In some examples, the first swing member 252 can have a straight rod structure, or in some other examples, the first swing member 252 can have an arc-shaped rod structure. The specific shape of the first swing member 252 is not limited in the embodiments of the present application.

[0071] The extension direction of the first driving sliding groove 249 can be parallel to the first direction X. For example, the first driving sliding groove 249 can have a waist-round shape, and the extension direction of the first driving sliding groove 249 can be parallel to the first direction X. Through the above arrangement, it is beneficial to avoid the second end 2522 of the first swing member from being stuck when sliding in the first driving sliding groove 249.

[0072] In some embodiments, the first end 2521 of the first swing member can also be installed on the base 210. For example, as shown in FIG. 2B, the base 210 can further include a mounting protrusion 213. The mounting protrusion 213 can have an assembly hole 2131 penetrating therethrough, the first protruding column 252a can be arranged in the assembly hole 2131 and connected with the first driving member 251, and the first protruding column 252a can be further connected with the assembly hole 2131 through a snap spring. The first protruding column 252a and the assembly hole 2131 can be in clearance fit, so that the first protruding column 252a can rotate in the assembly hole 2131. Figure 6

[0073] Figure 8 FIG. 2A shows a structural diagram of a base 210, a first driving assembly 250 and a second driving assembly 260 provided in the embodiments of the present application. In some embodiments, referring to FIG. 2A, the base 210 can have a first driving assembly 250 and a second driving assembly 260. The first driving assembly 250 can be installed on the base 210, and the second driving assembly 260 can be installed on the base 210. Figure 8 ​The first driving member 251 can include a driving motor 2511, and an output shaft of the driving motor 2511 is connected with the first end 2521 of the first swing member. The output shaft of the driving motor 2511 and the first end 2521 of the first swing member can be directly connected, or the output shaft of the driving motor 2511 and the first end 2521 of the first swing member can be connected through a transmission component, which is not limited in the embodiments of the present application. Through the above arrangement, in the process of switching from the retracted state to the pop-up state, the output shaft of the driving motor 2511 can drive the first swing member 252 to rotate. Similarly, in the process of switching from the pop-up state to the retracted state, the output shaft of the driving motor 2511 can drive the first swing member 252 to rotate.

[0074] Further, the rotation axis L1 of the first swing member 252 relative to the first driving member 251 can be parallel to the second direction Y. For example, the center line of the output shaft of the driving motor 2511 can coincide with the rotation axis of the first swing member 252 relative to the first driving member 251, and the output shaft of the driving motor 2511 can be parallel to the second direction Y, so that the rotation axis of the first swing member 252 relative to the first driving member 251 can also be parallel to the second direction Y.

[0075] Continuing to refer to Figure 8 The first driving member 251 can further include a speed reducer 2512, the output shaft of the driving motor 2511 is connected with the input shaft of the speed reducer 2512, the output shaft of the speed reducer 2512 is connected with the first end 2521 of the first swing member, and the first swing member 252 and the driving motor 2511 are located on the same side of the speed reducer 2512. For example, the output shaft of the driving motor 2511, the output shaft of the speed reducer 2512 and the input shaft of the speed reducer 2512 are all parallel to the second direction Y. Through the above arrangement, the speed reducer 2512 can reduce the rotating speed of the first swing member 252 while transmitting power, so as to adapt to the lifting speed requirement of the camera module 2. The first swing member 252 and the driving motor 2511 can be located on the same side of the speed reducer 2512, which is beneficial to improve the compactness of the layout of the first driving member 251 and reduce the occupied space of the first driving member 251.

[0076] Referring to Figure 9 When the lifting mechanism 200 is in the retracted state, the distance between the lifting member 240 and the first surface 2101 in the pop-up direction Z is the first distance D1. Through the above arrangement, the distance between the lifting member 240 and the first surface 2101 is small, so that at least part of the camera module 2 can be retracted into the accommodating cavity 15, so as to avoid the part of the camera module 2 protruding out of the shell being too much, and further avoid the damage of the camera module 2.

[0077] Combined with Figure 9 andFigure 10 In the process of switching from the retracted state to the popped-out state, the first swing member 252 moves towards the pop-out direction Z by the first driving member 251. Through the above arrangement, in the process of switching from the retracted state to the popped-out state, the first swing member 252 moves towards the pop-out direction Z by the first driving member 251, and the movement of the second end 2522 of the first swing member can be decomposed into two parts, one part is the movement component in the extension direction of the first driving sliding groove 249, which can make the second end 2522 of the first swing member slide in the first driving sliding groove 249; the other part is the movement component in the pop-out direction Z, which can make the first swing member 252 drive the lifting member 240 to move along the pop-out direction Z and increase the distance between the lifting member 240 and the first surface 2101.

[0078] With reference to Figure 10 When the lifting mechanism 200 is in the popped-out state, the distance between the lifting member 240 and the first surface 2101 in the pop-out direction Z is a second distance D2, and the second distance D2 is greater than the first distance D1. Through the above arrangement, at least part of the camera module 2 can be extended from the containing cavity 15 to improve the optical available space of the camera module 2 and achieve high-quality shooting.

[0079] Further, with reference to Figure 5 and Figure 7 The boss 212 of the base 210 can further include a first buckle 215, and correspondingly, the lifting member 240 can include a first clamping block 241 matched with the first buckle 215. When the lifting member 240 is assembled with the base 210, the lifting member 240 can be sleeved outside the boss 212 of the base 210. When the lifting member 240 is in the retracted state, the first clamping block 241 is arranged in a spaced manner with the first buckle 215; in the process of switching from the retracted state to the popped-out state, the first buckle 215 moves towards the first clamping block 241; when the lifting mechanism 200 is in the popped-out state, the first buckle 215 and the first clamping block 241 are in contact with each other, and the first buckle 215 can play a limiting role to avoid the lifting member 240 from being separated from the base 210.

[0080] In some embodiments, in combination with Figure 2 , Figure 3 and Figure 4As shown, the lifting mechanism 200 may further include a structural member 230, which is slidably connected to the lifting member 240 along the ejection direction Z. For example, at least a portion of the structural member 230 may be sleeved over the lifting member 240. The inner wall of the structural member 230 may have guide ribs 237, and correspondingly, the outer wall of the lifting member 240 may have guide grooves 246. The structural member 230 and the lifting member 240 can be slidably connected via the guide ribs 237 and the guide grooves 246.

[0081] Furthermore, a portion of the structural component 230 can also be arranged with the lens assembly 21 along the pop-out direction Z. The orthographic projection of the structural component 230 onto a plane perpendicular to the pop-out direction Z can at least partially overlap with the orthographic projection of the lens assembly 21 onto the same plane, so that the structural component 230 can shield the lens assembly 21 in the pop-out direction Z. The structural component 230 can be used to display a portion of the appearance of the camera module 2 and protect the lens assembly 21. The structural component 230 can also have a third through-hole 239, and at least a portion of the lens assembly 21 can correspond to the third through-hole 239. When the lifting mechanism 200 is in the retracted state, the distance between the structural component 230 and the rear cover 14 in the pop-out direction Z can be a first gap, where the first gap can be 0, meaning that the structural component 230 can be coplanar with at least a portion of the surface of the rear cover 14. During the transition from the retracted state to the pop-out state, the lens assembly 21 can drive the structural component 230 to move along the pop-out direction Z. When the lifting mechanism 200 is in the pop-out state, the distance between the structural component 230 and the rear cover 14 in the pop-out direction Z can be a second spacing, which can be greater than the first spacing.

[0082] Furthermore, combined Figure 7 As shown, the lifting member 240 may further include a second latch 242, and correspondingly, the structural member 230 may include a second latch 236 that cooperates with the second latch 242. The cooperation of the second latch 242 and the second latch 236 prevents the structural member 230 from disengaging from the lifting member 240.

[0083] Figure 11 for Figure 9 Cross-sectional view of the middle structure along section line AA; Figure 12 for Figure 10 Cross-sectional view of the middle structure along the BB section line; Figure 13 A schematic diagram illustrating the motion principle of a first swing member 252 provided in this application embodiment, wherein, Figure 13 The dashed lines represent the positions of the first swing member and the first drive slide when the lifting mechanism is in the retracted state, while the solid lines represent the positions of the first swing member and the first drive slide when the lifting mechanism is in the extended state. See below for reference. Figure 11 to Figure 13 The position of the first swinging member 252 under different states is explained.

[0084] In some embodiments, refer to Figure 12 When the lifting mechanism 200 is in the pop-out state, the direction from the first end 2521 of the first swing member to the second end 2522 of the first swing member can be parallel to the pop-out direction Z. For example, when the first swing member 252 is approximately a straight rod structure, the direction from the first end 2521 of the first swing member to the second end 2522 of the first swing member is also the extension direction of the straight rod structure of the first swing member 252.

[0085] With the above configuration, in the pop-out direction Z, the lifting member 240 can be strongly supported by the first swing member 252, so that a dead point can be formed between the lifting member 240 and the first swing member 252 in the pop-out direction Z. Here, the "dead point" refers to the angle between the normal direction of the contact point between the first drive slide 249 and the first swing member 252 and the direction pointing from the first end 2521 of the first swing member to the second end 2522 of the first swing member, which is 0 degrees. The lifting of the lifting member 240 cannot drive the rotation of the first swing member 252. When the lifting mechanism 200 is in the pop-out state and is subjected to impacts such as falling or pressing, the impact force on the lifting member 240 can be prevented from being transmitted to the first drive member 251 through the first swing member 252, thereby protecting the first drive member 251 and improving its reliability.

[0086] In some other embodiments, when there is friction between the first drive slide 249 and the first swing member 252, the direction from the first end 2521 of the first swing member to the second end 2522 of the first swing member can also intersect the ejection direction Z. In this case, a dead point can also be formed between the lifting member 240 and the first swing member 252 in the ejection direction Z. Here, "dead point" refers to the angle between the normal direction of the contact point between the first drive slide 249 and the first swing member 252 and the direction from the first end 2521 of the first swing member to the second end 2522 of the first swing member, which is greater than 0 and less than or equal to arctan(u), where u is the coefficient of friction between the first drive slide 249 and the first swing member 252.

[0087] Furthermore, combined Figure 13 As shown, when the lifting mechanism 200 is in the pop-out state, the second end 2522 of the first swing member can contact the side wall of the first driving slide 249 in the extending direction of the first driving slide 249. When the extending direction of the first driving slide 249 is parallel to the first direction X, the first driving slide 249 includes two opposing side walls in the first direction X, one of which contacts the second end 2522 of the first swing member.

[0088] With the above arrangement, the side wall of the first driving sliding groove 249 can be used to block the second end 2522 of the first swing piece from continuing to move, which is conducive to ensuring that the direction from the first end 2521 of the first swing piece to the second end 2522 of the first swing piece is parallel to the ejection direction Z, and conducive to ensuring that the first swing piece 252 strongly supports the lifting piece 240, thereby further ensuring the reliability of the first driving piece 251.

[0089] In some embodiments, in combination with Figure 11 and Figure 12 As shown in FIG. 12, when the lifting mechanism 200 is in the retracted state, the distance between the second end 2521 of the first swing piece and the first surface 2101 in the ejection direction Z is a third distance H2. When the lifting mechanism 200 is in the ejected state, the distance between the second end 2521 of the first swing piece and the first surface 2101 in the ejection direction Z is a fourth distance D3, and the fourth distance D3 is greater than the third distance H2.

[0090] With the above arrangement, during the process of the lifting mechanism 200 converting from the retracted state to the ejected state, the second end 2522 of the first swing piece rotates relative to the first end 2521 of the first swing piece in a direction away from the first surface 2101, so that the distance between the second end 2521 of the first swing piece and the first surface 2101 becomes larger.

[0091] In some embodiments, when the lifting mechanism 200 is in the retracted state, the distance H1 between the first end 2521 of the first swing piece and the first surface 2101 in the ejection direction Z can be equal to the third distance H2 between the second end 2521 of the first swing piece and the first surface 2101. That is, the direction from the first end 2521 of the first swing piece to the second end 2521 of the first swing piece can be parallel to the first direction X. Since the lifting mechanism 200 is in the ejected state, the direction from the first end 2521 of the first swing piece to the second end 2522 of the first swing piece is parallel to the ejection direction Z. During the process of the lifting mechanism 200 converting from the retracted state to the ejected state, the second end 2522 of the first swing piece rotates 90° relative to the first end 2521 of the first swing piece.

[0092] Alternatively, in some embodiments, when the lifting mechanism 200 is in the retracted state, the distance H1 between the first end 2521 of the first swing piece and the first surface 2101 in the ejection direction Z can be less than the third distance H2 between the second end 2521 of the first swing piece and the first surface 2101. During the process of the lifting mechanism 200 converting from the retracted state to the ejected state, the second end 2522 of the first swing piece rotates relative to the first end 2521 of the first swing piece at an angle less than 90°.

[0093] Alternatively, in some embodiments, in combination with Figure 11, when the lifting mechanism 200 is in the retracted state, the distance H1 between the first end 2521 of the first swing piece and the first surface 2101 in the ejection direction Z can be greater than the distance H2 between the second end 2522 of the first swing piece and the first surface 2101. In combination with Figure 13 , as shown in the drawings, when the lifting mechanism 200 is in the retracted state, the second end 2522 of the first swing piece is closer to the base 210 than the first end 2521 of the first swing piece, and the first drive slot 249 can have two opposite side walls in the first direction X, the second end 2522 of the first swing piece is located between the two opposite side walls of the first drive slot 249 in the first direction X, and the second end 2522 of the first swing piece can not be in contact with both side walls.

[0094] Through the above arrangement, referring to Figure 13 , in the process of converting the lifting mechanism 200 from the retracted state to the ejected state, the second end 2522 of the first swing piece needs to rotate an angle greater than 90° relative to the first end 2521 of the first swing piece.

[0095] When the lifting distance of the lifting piece 240 is the same, compared with the above two, the embodiment using the first swing piece 252 to rotate a smaller angle can realize the conversion from the retracted state to the ejected state (for example, the second end 2522 of the first swing piece rotates less than 90° relative to the first end 2521 of the first swing piece), and in the embodiment of the present application, since H1 is greater than H2, the size of the first end 2521 of the first swing piece pointing to the second end 2622 of the second swing piece can be reduced, thereby facilitating the reduction of the occupied space of the first drive assembly 250.

[0096] When the size of the first end 2521 of the first swing piece pointing to the second end 2622 of the second swing piece is the same, compared with the above two, the embodiment using the first swing piece 252 to rotate a smaller angle can realize the conversion from the retracted state to the ejected state, and in the embodiment of the present application, since H1 is greater than H2, the lifting distance of the lifting piece 240 is increased.

[0097] In the embodiment of the present application, the distance H3 between the first end 2521 of the first swing piece and the second end 2522 of the first swing piece can be less than or equal to the size H4 of the first drive slot 249 in the first direction X. In combination with Figure 11 , Figure 12 and Figure 13 , by increasing the size H4 of the first drive slot 249 in the first direction X, the moving distance of the second end 2522 of the first swing piece in the first drive slot 249 is increased, so that the movement component of the second end 2522 of the first swing piece in the first direction X is increased. Correspondingly, in order to make the first end 2521 of the first swing piece rotate from the position in Figure 11 to the position in Figure 12In the position, in the process of the conversion of the lifting mechanism 200 from the retracted state to the ejected state, the second end 2522 of the first swing piece needs to rotate a larger angle relative to the first end 2521 of the first swing piece, which is beneficial to increase the movement component of the second end 2522 of the first swing piece in the ejection direction Z, increase the distance of the movement of the lifting piece 240 along the ejection direction Z driven by the first swing piece 252, and is beneficial to ensure that at least part of the camera module 2 extends out of the accommodating cavity 15 when the lifting mechanism 200 is in the ejected state, so as to realize high-quality shooting.

[0098] In some embodiments, in combination with Figure 5 , Figure 7 and Figure 8 , the lifting piece 240 can further include a second driving sliding groove 248, the second driving sliding groove 248 is arranged in the second direction Y and is spaced from the first driving sliding groove 249, and the extension direction of the second driving sliding groove 248 intersects the ejection direction Z. For example, the structure of the second driving sliding groove 248 and the first driving sliding groove 249 can be the same. For example, the extension direction of the second driving sliding groove 248 can also be parallel to the first direction X. Alternatively, the second driving sliding groove 248 can also have other shapes, for example, the second driving sliding groove 248 can also be an arc-shaped sliding groove, and the specific shape of the second driving sliding groove 248 is not limited in the embodiments of the present application.

[0099] Based on the above structure, the lifting mechanism 200 can further include a second driving assembly 260, the second driving assembly 260 can be mounted on the base 210, the second driving assembly 260 and the first driving assembly 250 are arranged in the second direction Y, the second driving assembly 260 includes a second driving piece 261 and a second swing piece 262, the first end 2621 of the second swing piece is connected with the second driving piece 261, and the second end 2622 of the second swing piece is slidably connected with the second driving sliding groove 248. For example, the second swing piece 262 can have a substantially rod-shaped structure, the first end 2621 of the second swing piece can have a third protruding column 262a connected with the second driving piece 261, and the second end 2622 of the second swing piece can have a fourth protruding column 262b slidably connected with the second driving sliding groove 248. For example, the second swing piece 262 can be a straight rod, or in some other examples, the second swing piece 262 can also be an arc-shaped rod. The specific shape of the second swing piece 262 is not limited in the embodiments of the present application.

[0100] As described in the above embodiments, in the process of switching from the retracted state to the popped-out state, the second swing member 262 is rotated by the second driving member 261 toward the pop-out direction Z. Through the above arrangement, in the process of switching from the retracted state to the popped-out state, the second swing member 262 is moved by the second driving member 261 toward the pop-out direction Z, and the movement of the second end 2622 of the second swing member can be decomposed into two parts, one part is the movement component in the extension direction of the second driving sliding groove 248, which can make the second end 2622 of the second swing member slide in the second driving sliding groove 248; the other part is the movement component in the pop-out direction Z, which can make the second swing member 262 drive the lifting member 240 to move along the pop-out direction Z, and increase the distance between the lifting member 240 and the first surface 2101. Through the above arrangement, at least part of the camera module 2 can be extended from the containing cavity 15 to increase the optical available space of the camera module 2, so as to realize high-quality shooting.

[0101] In some embodiments, continuing to refer to Figure 8 , the first driving assembly 250 and the second driving assembly 260 are arranged in a center-symmetrical manner about the lifting member 240. Here, the "center-symmetrical" can be understood as that the first driving assembly 250 and the second driving assembly 260 can be absolutely center-symmetrical and approximately center-symmetrical. Among them, the approximately center-symmetrical can be understood as that the overall structure of the first driving assembly 250 and the second driving assembly 260 is symmetrical, and there is a change in the local part of the first driving assembly 250 and the second driving assembly 260. Among them, there can be a difference between the sizes of the first driving assembly 250 and the second driving assembly 260 which are symmetrical in trend, and the floating range of the existing difference does not exceed the error threshold value. Among them, the specific value of the error threshold value is not limited in the present disclosure, as long as the gap is within the error threshold value.

[0102] For example, the second driving member 261 can also include a driving motor 2611 and a speed reducer 2612, wherein the driving motor 2611 of the second driving member 261 and the driving motor 2511 of the first driving member 251, the speed reducer 2612 of the second driving member 261 and the speed reducer 2512 of the first driving member 251 are arranged in a center-symmetrical manner about the lifting member 240.

[0103] For example, the first swing member 252 and the second swing member 262 can be arranged symmetrically about the center of the lifting member 240. For example, the first swing member 252 and the second swing member 262 can have the same structure. When the second end 2522 of the first swing member slides in the first drive slot 249 and the second end 2622 of the second swing member slides in the second drive slot 248, the movement component of the second end 2522 of the first swing member in the extension direction of the first drive slot 249 is opposite to the movement component of the second end 2622 of the second swing member in the extension direction of the second drive slot 248, so that the sliding direction of the second end 2522 of the first swing member in the first drive slot 249 is opposite to the sliding direction of the second end 2622 of the second swing member in the second drive slot 248.

[0104] Similarly, when the lifting mechanism 200 is in the pop-out state, the direction from the first end 2621 of the second swing member to the second end 2622 of the second swing member can be parallel to the pop-out direction Z, and the second end 2622 of the second swing member can be in contact with the side wall of the second drive slot 248 in the extension direction of the second drive slot 248. Through the above arrangement, the lifting member 240 can be strongly supported by the second swing member 262 in the pop-out direction Z, so that a dead point can be formed between the lifting member 240 and the second swing member 262 in the pop-out direction Z. When the lifting mechanism 200 is in the pop-out state and is subjected to an impact such as falling or pressing, the impact force acting on the lifting member 240 can be prevented from being transmitted to the second driving member 261 through the second swing member 262, thereby facilitating the protection of the second driving member 261 and improving the reliability of the second driving member 261.

[0105] Similarly, when the lifting mechanism 200 is in the pop-out state, the distance between the first end 2521 of the first swing member and the first surface 2101 in the pop-out direction Z can be greater than the distance between the second end 2522 of the first swing member and the first surface 2101, and the second end 2522 of the first swing member can not be in contact with the side wall of the second drive slot 248 in the first direction X. Through the above arrangement, during the conversion of the lifting mechanism 200 from the retracted state to the pop-out state, the second end 2522 of the first swing member needs to rotate an angle greater than 90° relative to the first end 2521 of the first swing member, and the size from the first end 2521 of the first swing member to the second end 2622 of the second swing member can be reduced, thereby facilitating the reduction of the occupied space of the first driving assembly 250.

[0106] Through the above arrangement, the driving force of the first driving assembly 250 and the driving force of the second driving assembly 260 received by the lifting piece 240 during the process of switching from the retracted state to the ejected state can also be arranged in a central symmetry, so as to make the lifting piece 240 bear force uniformly, and facilitate to improve the smoothness of the movement of the lifting piece 240 along the ejection direction Z.

[0107] In some embodiments, with reference to Figure 14a , the lifting mechanism 200 can further include a first sensor 293, a second sensor 294, a first circuit board 291, and a second circuit board 292. The first sensor 293 can be mounted on the first circuit board 291, and the second sensor 294 can be mounted on the second circuit board 292. The first circuit board 291 and the second circuit board 292 can also be connected with the mainboard of the electronic device 1. The first sensor 293 and the second sensor 294 can be magnetic sensors, such as Hall sensors, TMR (Tunnel Magneto Resistance) sensors, etc.

[0108] Taking only the first circuit board 291 in Figure 14b as an example, the mounting mode of the first circuit board 291 and the second circuit board 292 is described. Exemplarily, the mounting boss 213 parallel to the base 210 can be arranged spaced apart from the boss 212 of the base 210. The first circuit board 291 can be a flexible circuit board. The first circuit board 291 can be bonded to the metal sheet part 299, and the metal sheet part 299 is also bonded to the surface of the mounting boss 213 facing the boss 212. Similarly, the second circuit board 292 can also be bonded to the metal sheet part and mounted on the surface of the mounting boss 213 facing the boss 212 through the metal sheet part.

[0109] Correspondingly, the lifting mechanism 200 can further include a first magnetic part 2471 and a second magnetic part 2472. The first magnetic part 2471 and the second magnetic part 2472 can be arranged on the lifting piece 240, so that the first magnetic part 2471 and the second magnetic part 2472 can move together with the lifting piece 240.

[0110] Taking only the first magnetic part 2471 in Figure 14b as an example, the mounting mode of the first magnetic part 2471 and the second magnetic part 2472 is described. Exemplarily, the surface of the lifting piece 240 facing the mounting boss 213 can have a matching groove 245, and the first magnetic part 2471 can be mounted in the matching groove 245. Similarly, the second magnetic part 2472 can also be mounted in the groove arranged on the lifting piece 240 facing the mounting boss 213.

[0111] With the above arrangement, when the first magnetic member 2471 and the second magnetic member 2472 move with the lifting member 240, the magnetic field of the first magnetic member 2471 and the second magnetic member 2472 collected by the first sensor 293 and the second sensor 294 changes, so that the data transmitted by the first sensor 293 to the first circuit board 291 changes, the data transmitted by the second sensor 294 to the second circuit board 292 changes, and the mainboard of the electronic device 1 can obtain the position information of the lifting mechanism 200 through the magnetic field information collected by the first sensor 293 and the second sensor 294.

[0112] In some embodiments, in combination with Figure 9 , Figure 10 , Figure 15 , Figure 16 and Figure 17 , the lifting mechanism 200 can further include a first sliding rail 271, a rolling body 274, and a second sliding rail 272. The first sliding rail 271 can be connected with the base 210, the second sliding rail 272 can be connected with the lifting member 240, and the rolling body 274 can be arranged to roll between the first sliding rail 271 and the second sliding rail 272.

[0113] For example, as shown in Figure 6 , the outer side of the boss 212 can have a first clamping groove 218 with a clamping hole 2181 penetrating the groove bottom of the first clamping groove 218, the first sliding rail 271 can be arranged in the first clamping groove 218, and the first sliding rail 271 can be clamped and connected with the clamping hole 2181, so that the first sliding rail 271 can be detachably connected with the base 210. For example, as shown in Figure 7 , the inner side of the lifting member 240 can have a second clamping groove 243, and the second sliding rail 272 can be clamped and connected with the second clamping groove 243, so that the second sliding rail 272 can be detachably connected with the lifting member 240.

[0114] For example, as shown in Figure 17 , the first sliding rail 271 can have a first sliding groove 2713, and the extension direction of the first sliding groove 2713 can be parallel to the ejection direction Z. For example, the first sliding rail 271 can have a substantially plate-like structure, and the extension direction of the first sliding rail 271 can be the length direction of the plate-like structure. In the width direction of the plate-like structure, the first sliding rail 271 can have two oppositely arranged first folded edges 2714, one first folded edge 2714 can be recessed in a direction away from the other first folded edge 2714 to form a first sliding groove 2713, and the groove bottom of the first sliding groove 2713 can include a curved surface.

[0115] Further, the first slide rail 271 can further include a first stop plate 2711 and a second stop plate 2712 arranged along the ejecting direction Z, and the distance between the first stop plate 2711 and the first surface 2101 is greater than the distance between the second stop plate 2712 and the first surface 2101 along the ejecting direction Z. For example, the first stop plate 2711 can be located at the upper end of the first slide rail 271, and the second stop plate 2712 can be located at the lower end of the second slide rail 272.

[0116] The second slide rail 272 can have a second slide groove 2723, and the extension direction of the second slide groove 2723 can be parallel to the ejecting direction Z. The second slide rail 272 can have a substantially plate structure, and the extension direction of the second slide rail 272 can be the length direction of the plate structure. Along the width direction of the plate structure, the second slide rail 272 can have two oppositely arranged second folded edges 2724, one of which can be recessed to form the second slide groove 2723, and the groove bottom of the second slide groove 2723 can include a curved surface.

[0117] The rolling body 274 can be arranged to roll between the first slide groove 2713 and the second slide groove 2723. For example, the shape of the rolling body 274 can include a spherical body, and the rolling body 274 can be arranged to roll between the groove bottom of the first slide groove 2713 and the groove bottom of the second slide groove 2723. Through the above arrangement, the rolling body 274 can roll between the first slide groove 2713 and the second slide groove 2723, so that the first slide rail 271 can move relative to the second slide rail 272, and the first slide rail 271 and the second slide rail 272 can play a guiding role, so that the lifting member 240 and the base 210 can move relative to each other through the first slide rail 271 and the second slide rail 272, which is beneficial to ensure the smoothness of the movement between the lifting member 240 and the base 210.

[0118] In some embodiments, referring to Figure 15 and Figure 16 When the lifting mechanism 200 is in the retracted state, the second slide rail 272 can be in contact with the second stop plate 2712. When the lifting mechanism 200 is in the ejecting state, the second slide rail 272 can be in contact with the first stop plate 2711. For example, at least part of the second slide rail 272 can be located between the first stop plate 2711 and the second stop plate 2712. Through the above arrangement, the first stop plate 2711 and the second stop plate 2712 can both play a limiting role, wherein the first stop plate 2711 can be used to block the second slide rail 272 from continuing to move away from the first surface 2101, and the second stop plate 2712 can be used to block the second slide rail 272 from continuing to move towards the first surface 2101, thereby avoiding the second slide rail 272 from falling out of the first slide rail 271 during sliding.

[0119] In some embodiments, the number of the rolling bodies 274 can be multiple, and the multiple rolling bodies 274 can be arranged at intervals along the ejection direction Z. The lifting mechanism 200 further comprises a retainer 273, which is located between the first sliding groove 2713 and the second sliding groove 2723. The retainer 273 comprises multiple mounting holes 2742 arranged at intervals along the ejection direction Z, and one rolling body 274 is mounted in one mounting hole 2742.

[0120] As shown in the examples, Figure 17 the retainer 273 can be substantially in the form of a plate structure. Along the width direction of the plate structure, the retainer 273 can have two oppositely arranged third folded edges 2741. Along the ejection direction Z, the third folded edges 2741 can have multiple mounting holes 2742 arranged at intervals, and the mounting holes 2742 can pass through the third folded edges 2741. The number of the rolling bodies 274 can be the same as the number of the mounting holes 2742, so that the rolling bodies 274 and the mounting holes 2742 can be arranged one-to-one. Along the ejection direction Z, the distance between the retainer 273 and the first stop plate 2711 can be twice the distance between the second sliding rail 272 and the first stop plate 2711. During the switching of the lifting mechanism 200 from the retracted state to the ejected state, the moving stroke length of the second sliding rail 272 along the ejection direction Z can be twice the moving stroke length of the retainer 273 along the ejection direction Z.

[0121] By arranging the retainer 273, the multiple rolling bodies 274 can be guided and retained between the first sliding rail 271 and the second sliding rail 272. By arranging the multiple rolling bodies 274, the friction of the second sliding rail 272 relative to the first sliding rail 271 can be further reduced, and the moving smoothness between the lifting member 240 and the base 210 can be further improved.

[0122] In addition, at least part of the second sliding rail 272 and at least part of the rolling bodies 274 can be located in the groove surrounded by the first sliding rail 271, which can reduce the occupied space of the second sliding rail 272 and the rolling bodies 274, and improve the compactness of the structural layout of the lifting mechanism 200.

[0123] Continuing to refer to Figure 9 and Figure 10 , the first sliding rail 271, the retainer 273, the second sliding rail 272, and the multiple rolling bodies 274 can collectively constitute a guide assembly. The lifting mechanism 200 can comprise multiple guide assemblies, and the guide assemblies can be arranged at intervals along the circumferential direction of the boss 212.

[0124] In some embodiments, referring to Figure 4 , Figure 18 and Figure 19The lifting mechanism 200 can further include an elastic body 280 arranged between the lifting member 240 and the structural member 230 in the ejecting direction Z. For example, the elastic body 280 can include a spring, one end of which is in contact with the lifting member 240 and the other end of which is in contact with the structural member 230.

[0125] In some embodiments, the structural member 230 can include a first guide column 238, the lifting member 240 can include a second guide column 247, and the elastic body 280 can be sleeved on the first guide column 238 and the second guide column 247. Through the above arrangement, the first guide column 238 and the second guide column can guide the elastic body 280.

[0126] In some embodiments, the structural member 230 can include a first guide column 238, the lifting member 240 can include a second guide column 247, and the elastic body 280 can be sleeved on the first guide column 238 and the second guide column 247. Through the above arrangement, the first guide column 238 and the second guide column can guide the elastic body 280. Figure 18 When the lifting mechanism 200 is in the ejecting state and the lifting mechanism 200 is not subjected to external impact, the elastic body 280 is in a normal state. For example, the elastic body 280 can be in a normal state when the lifting mechanism 200 is not subjected to external impact. Figure 19 When the lifting mechanism 200 is in the ejecting state and the lifting mechanism 200 is subjected to external impact, the structural member 230 moves towards the lifting member 240 under the action of the external impact force, so that the elastic body 280 is in a compressed state. At this time, since the elastic body 280 can absorb part of the external impact force, it is beneficial to avoid the transmission of the external impact force to the lifting member 240, and then to the first driving member 251 or the second driving member 261 through the first swing member 252 or the second swing member 262, thereby benefiting the protection of the first driving member 251 or the second driving member 261 and improving the reliability of the first driving member 251 or the second driving member 261.

[0127] The above merely provides a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or replacements within the technical scope disclosed by the present application can be easily thought of by those skilled in the art, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
