Description

Lifting mechanism, camera module and electronic equipment

[0001] This application claims priority to Chinese patent application filed on December 25, 2024, with application number 202411960563.5, entitled "Lifting Mechanism, Camera Module and Electronic Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronic product technology, and in particular to a lifting mechanism, a camera module, and an electronic device. Background Technology

[0003] To meet the design requirements of thinner and lighter electronic devices, as well as users' requirements for shooting angle and focal length, the camera of electronic devices can extend out of the housing or retract into the housing as needed. That is, the height of the camera is reduced in static appearance, and when extended, the increased space is used to improve the camera performance, such as changing the shooting angle and focal length.

[0004] A pop-up camera may include a pop-up mechanism and a lens assembly. The pop-up mechanism covers the lens assembly, and when the lens assembly moves up and down, the pop-up mechanism also moves up and down, providing space for the lens assembly to move. However, the pop-up mechanism in related technologies provides poor protection for the lens assembly. Summary of the Invention

[0005] This application provides a lifting mechanism, a camera module, and an electronic device to improve the poor protection effect of the lifting mechanism in the camera module.

[0006] To achieve the above objectives, the embodiments of this application provide the following solutions:

[0007] On one hand, a lifting mechanism is provided, which is used to cover the lens assembly of a camera module. The camera module is mounted on the housing of an electronic device, and the lens assembly moves relative to the housing of the electronic device in a lifting direction.

[0008] The lifting mechanism includes a lifting component, a base, and a sealing component. The direction from the first end of the lifting component to the second end is the lifting direction. The direction from the first end of the base to the second end intersects the lifting direction. The first end of the base can rotate relative to the second end of the base. The first end of the base is arranged around the lifting component, and there is a gap between the side wall of the lifting component and the first end of the base. The lifting component can move relative to the second end of the base.

[0009] With the above configuration, when the lifting mechanism is in the retracted state, at least a portion of the camera module can be retracted into the enclosed cavity, reducing the protrusion of the camera module outside the back cover. This helps prevent damage to the camera module and improves its reliability. When the lifting mechanism is in the extended state, at least a portion of the camera module can extend out of the cavity, increasing the available optical space for the camera module and enabling high-quality shooting.

[0010] The sealing element includes a main body, a first sealing ring, and a second sealing ring. The first sealing ring is located on one side of the first end of the base along the lifting direction and is circumferentially connected to the first end of the base. The second sealing ring is located on one side of the second end of the lifting element along the lifting direction and is circumferentially connected to the second end of the lifting element. The main body connects the first sealing ring and the second sealing ring. The main body can be stretched or contracted in the direction from the first sealing ring to the second sealing ring and can cover the gap.

[0011] With the above configuration, during the transition between the retracted and extended states of the lifting mechanism, the first end of the first base drives the first sealing ring to rotate relative to the second end of the base, and the second end of the lifting component drives the second sealing ring to move relative to the second end of the base. When there is relative movement between the first and second sealing rings, the main body can stretch or retract in the direction from the first sealing ring to the second sealing ring, thus shielding the gap between the first end of the base and the second end of the lifting component. This prevents external debris from entering the equipment through the gap, thereby providing dynamic protection for the first end of the base and the second end of the lifting component.

[0012] Furthermore, since the first sealing ring is located at one end of the base along the lifting direction and the second sealing ring is located at one end of the lifting component along the lifting direction, the sealing component is located on the outer surface of the lifting component and the base. The sealing component, the base, and the lifting component can together form the appearance of the camera module, which is beneficial to improving the aesthetics of the equipment.

[0013] In some embodiments, the main body includes a plurality of pleats arranged in sequence, the pleats surrounding the lifting member.

[0014] With the above configuration, the body portion can achieve changes in the size of the folds through compression and stretching, without compressing or stretching the material of the body portion itself. This allows the body portion provided in the embodiments of the present invention to be repeatedly compressed and stretched, which is beneficial to improving the service life of the seal.

[0015] In some embodiments, the plurality of sequentially arranged folds include a first fold and a second fold. When the lifting structure is in a retracted state, the first fold is closer to the first sealing ring than the second fold. The closed pattern formed by the turning end 2357 of the first fold is the same as the closed pattern formed by the turning end 2357 of the second fold, and the area of ​​the closed pattern formed by the turning end 2357 of the first fold is larger than the area of ​​the closed pattern formed by the turning end 2357 of the second fold.

[0016] The above design helps to better conceal the gap between the base and the lifting component, thus improving the aesthetic appearance of the equipment. Furthermore, during the transition between the stretched and contracted states, the design ensures that the multiple folds within the body are evenly stressed, preventing excessive stretching or compression and thereby enhancing the reliability of the body.

[0017] In some embodiments, the thickness of the pleats is less than or equal to the thickness of the first sealing ring; and / or, the thickness of the pleats is less than or equal to the thickness of the second sealing ring.

[0018] In this embodiment, reducing the thickness of the folds helps to improve the elastic tensile force of the folds, which helps to increase the speed of the tensile deformation of the body part when it changes from a contracted state to a stretched state; furthermore, reducing the thickness of the folds also helps to improve the elastic recovery force of the folds, which helps to increase the recovery speed of the body part when it changes from a stretched state to a contracted state.

[0019] In some embodiments, the main body further includes a curved structure that surrounds the lifting member. A first end of the curved structure is connected to a first sealing ring or a second sealing ring, and a second end of the curved structure is connected to a pleat. The thickness of the first end of the curved structure is greater than the thickness of the second end of the curved structure.

[0020] The above-mentioned settings can strengthen the connection between the main body and the first sealing ring, which helps to improve the reliability of the seal and extend its service life.

[0021] In some embodiments, when the lifting mechanism is in a retracted state, the direction from the first end of the base to the second end of the base is a first direction, which is perpendicular to the lifting direction. In the lifting direction, the distance between the second end of the lifting member and the second end of the base is a first distance. The distance between the first end of the main body and the second end of the base is greater than the distance between the second end of the main body and the second end of the base. In the lifting direction, the size of the first end of the main body is equal to the size of the second end of the main body.

[0022] When the lifting mechanism is in the pop-out state, the direction from the first end of the base to the second end of the base intersects with the lifting direction and the first direction, respectively. In the lifting direction, the distance between the second end of the lifting component and the second end of the base is the second distance, which is greater than the first distance. In the lifting direction, the size of the first end of the main body is smaller than the size of the second end of the main body.

[0023] With the above settings, when the lifting mechanism is in the retracted or extended state, the first end of the main body can be deformed by contraction or extension to cover the gap on one side of the lifting component and the base, and the second end of the main body can be deformed by contraction or extension to cover the gap on the other side of the lifting component and the base, preventing external debris from entering the equipment through the gap. Thus, the seal can achieve dynamic protection for the first end of the base and the second end of the lifting component.

[0024] In some embodiments, when the lifting mechanism is in the retracted state, the dimension of the first end of the main body in the lifting direction is a first dimension. When the lifting mechanism is in the extended state, the dimension of the first end of the main body in the lifting direction is a second dimension, which is larger than the first dimension.

[0025] With the above settings, during the transition from the retracted state to the extended state of the lifting mechanism, the first end of the main body is stretched in the lifting direction, and during the transition from the extended state to the retracted state of the lifting mechanism, the first end of the main body is compressed in the lifting direction. Thus, the first end of the main body can shield the gap between the first end of the base and the second end of the lifting component, thereby achieving dynamic protection of the lifting mechanism.

[0026] In some embodiments, when the lifting mechanism is in the retracted state, in the first direction, the dimension of the first end of the main body is the third dimension, and the dimension of the second end of the main body is the fourth dimension. When the lifting mechanism is in the extended state, in the first direction, the dimension of the first end of the main body is the fifth dimension, which is larger than the third dimension, and the dimension of the second end of the main body is the sixth dimension, which is smaller than the fourth dimension.

[0027] With the above configuration, during the transition from the retracted state to the extended state of the lifting mechanism, the first end of the main body is stretched in the first direction, and the second end of the main body is retracted in the first direction; during the transition from the extended state to the retracted state of the lifting mechanism, the first end of the main body is retracted in the first direction, and the second end of the main body is stretched in the first direction. The first end and the second end of the main body thus shield the gap between the first end of the base and the second end of the lifting component, thereby achieving dynamic protection of the lifting mechanism.

[0028] In some embodiments, a first adhesive layer and a second adhesive layer are also included, wherein the first sealing ring is connected to the first end of the base through the first adhesive layer, and the second sealing ring is connected to the second end of the lifting member through the second adhesive layer.

[0029] The above arrangement connects the first sealing ring to the base, which improves the ease of connection between the two. Furthermore, connecting the second sealing ring to the lifting component also improves the ease of connection between them.

[0030] In some embodiments, the system further includes a first link and a second link. A first end of the first link is rotatable relative to a second end of the first link. The first end of the first link is slidably connected to a first end of the lifting member. The first end of the second link is rotatably connected to the first link, and the second end of the second link is rotatably connected to the base. By incorporating a first link and a second link in the linkage assembly, linkage between the base and the lifting member can be achieved.

[0031] In some embodiments, the second end of the first link is slidably connected to the first end of the lifting member, including: the first end of the first link and the first end of the lifting member are slidably connected via a first groove and a first slider, wherein the second end of the first link includes the first groove, and the first end of the lifting member includes the first slider. When the lifting mechanism is in the retracted state, the extension direction of the first groove is perpendicular to the lifting direction.

[0032] With the above configuration, during the transition of the lifting mechanism from the retracted state to the extended state, the first end of the first link can drive the lifting component to move, giving the lifting component a movement component in the lifting direction and a movement component in the first direction. Conversely, during the transition of the lifting mechanism from the extended state to the retracted state, the first end of the first link can drive the lifting component to move, giving the lifting component a movement component opposite to the lifting direction and a movement component opposite to the first direction.

[0033] On the other hand, a sealing element is provided for sealing the lifting mechanism as described in the above embodiments. The sealing element includes a main body, a first sealing ring, and a second sealing ring. The main body connects the first sealing ring and the second sealing ring. The main body includes multiple pleats, which are arranged sequentially in the direction from the first sealing ring to the second sealing ring.

[0034] On the other hand, a camera module is provided, including a lens assembly and the lifting mechanism in the above embodiments, wherein the lifting mechanism is covered outside the lens assembly.

[0035] The camera module provided in the embodiments of this application includes the lifting mechanism as described above, and therefore has all the above-described beneficial effects, which will not be repeated here.

[0036] On the other hand, an electronic device is provided, including a housing and a camera module as described in the above embodiments. The camera module is disposed on the housing, and the lens assembly of the camera module is movable relative to the housing in a lifting direction.

[0037] The electronic device provided in the embodiments of this application includes the camera module as described above, and therefore has all the above-described beneficial effects, which will not be repeated here. Attached Figure Description

[0054] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0055] In the following description, the terms "first," "second," etc., are used for ease of description only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "multiple" means two or more.

[0056] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0057] In the embodiments of this application, the directional indications used to explain the structure and movement of different components, such as up, down, left, right, front, and back, are relative. These indications are appropriate when the components are in the positions shown in the figures. However, if the description of the component positions changes, these directional indications will also change accordingly.

[0058] In the embodiments of this application, "parallel" and "perpendicular" include the described situation and situations similar to the described situation, the range of which is within an acceptable deviation range, wherein the acceptable deviation range is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range for approximate parallelism may be, for example, within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range for approximate perpendicularity may also be, for example, within 5°.

[0059] This application provides an electronic device, which may include mobile phones, tablets, smart bracelets, smartwatches, etc. This application does not limit the electronic device.

[0060] The following description uses a mobile phone as an example of an electronic device. It should be understood that the electronic device in this application is not limited to a mobile phone. Figure 1a is an exploded view of the structure of an electronic device provided in this application embodiment. Referring to Figure 1a, the electronic device 1 includes a housing 12 and a display panel 11. The housing 12 may include a middle frame 13 and a back cover 14. The display panel 11 covers one side of the middle frame 13, and the back cover 14 covers the other side of the middle frame 13. The middle frame 13 and the back cover 14 can form a cavity 15. The electronic device 1 also includes a battery 16 and a motherboard 17 disposed in the cavity 15. The motherboard 17 and the battery 16 can be fixed on the middle frame 13. The motherboard 17 is electrically connected to the battery 16 and the display panel 11.

[0061] In some embodiments, in order to enable the above-mentioned electronic device 1 to realize image acquisition, i.e., shooting function, the electronic device 1 provided in the above-mentioned embodiments of the present application may further include a camera module 2, which may be a front camera device or a rear camera device.

[0062] In some embodiments, when the camera module 2 is a rear camera device, a portion of the camera module 2 may be disposed within the rear cover 14 of the housing 12, and the camera module 2 may be electrically connected to the motherboard 17 so that the camera module 2 can take pictures or record videos under the control of the motherboard 17.

[0063] Figure 1b is a structural diagram of a camera module provided in an embodiment of this application. Referring to Figure 1b, in this embodiment, the camera module 2 further includes a lifting mechanism 200, which is mounted on the lens assembly 21. When the lens assembly 21 is lifted, the lifting mechanism 200 also lifts, providing lifting space for the lens assembly 21. The lens assembly 21 can move relative to the housing 12 along the lifting direction X.

[0064] The lens assembly 21 includes a light-transmitting cover plate, an optical lens, and an optical sensor. These components are arranged along the optical axis, with the optical sensor located on the image side of the optical lens and the light-transmitting cover plate on the object side. External light passes through the light-transmitting cover plate and the optical lens and is received by the optical sensor to form an image. The optical sensor is electrically connected to the mainboard 17 shown in Figure 1a to convert the received image into an electrical signal and send it to the mainboard 17, thereby enabling photography or video recording.

[0065] Referring to Figures 1a and 1b, the rear cover 14 is provided with an opening 18, which communicates with the receiving cavity 15. In some embodiments, the lens assembly 21 can be moved relative to the rear cover 14 in the thickness direction, so that the lens assembly 21 can be moved relative to the housing 12 in the lifting direction X.

[0066] When the lifting mechanism 200 is in the retracted state, at least a portion of the lens assembly 21 can be positioned directly opposite the opening 18, and at least a portion of the lens assembly 21 is located inside the receiving cavity 15. During the transition from the retracted state to the extended state, a portion of the lens assembly 21 extends out of the receiving cavity 15 through the opening 18. When the lifting mechanism 200 is in the extended state, at least a portion of the lens assembly 21 can be positioned directly opposite the opening 18, and at least a portion of the lens assembly 21 is located outside the receiving cavity 15.

[0067] With the above settings, when taking pictures using the electronic device 1, at least a portion of the camera module 2 extends out of the housing cavity 15 to increase the available optical space of the camera module 2 and achieve high-quality shooting; when shooting is not required, at least a portion of the camera module 2 retracts into the housing cavity 15 to avoid the camera module 2 protruding too much from the housing 12 and affecting the appearance of the electronic device 1.

[0068] In some embodiments of the related technology, the lifting mechanism 200 may include a mounting base and a lifting component. The mounting base is disposed on the rear cover 14, and the lifting component may pass through the mounting base and move up and down relative to the mounting base. The lens assembly may be positioned directly opposite the lifting component. However, there is a gap between the lifting component and the mounting base, which allows external substances to enter the device, reducing the protective effect on the lens assembly 21 and decreasing the reliability of the lens assembly.

[0069] Figure 2 is a structural diagram of a lifting mechanism 200 disposed on the back cover in a retracted state according to an embodiment of this application; Figure 3 is a structural diagram of a lifting mechanism 200 disposed on the back cover in a pop-up state according to an embodiment of this application; Figure 4 is an exploded view of the structure of a lifting mechanism 200 according to an embodiment of this application. The structure of the lifting mechanism 200 will be described below with reference to Figures 2, 3 and 4. The shape of the back cover 14 is merely exemplary; the back cover 14 can be polygonal, circular, etc., and is not limited thereto.

[0070] In this embodiment, the lifting mechanism 200 may include a base 220 and a lifting member 210, wherein the base 220 and the lifting member 210 may be disposed on the rear cover 14 of the housing 12. The lifting member 210 may include a first end 210a and a second end 210b, and the base 220 may include a first end 220a and a second end 220b.

[0071] For ease of explanation, the direction from the first end 210a of the lifting member to the second end 210b of the lifting member is defined as the lifting direction X, and the direction from the first end 220a of the base to the second end 220b of the base when the lifting mechanism 200 is in the retracted state is defined as the first direction Y. In some embodiments, the lifting direction X can be the thickness direction of the rear cover 14, and the first direction Y can be parallel to the rear cover 14 and perpendicular to the lifting direction X. Here, "lifting direction X" can be understood as the direction of movement of the lens assembly 21 in the camera module relative to the rear cover 14.

[0072] For example, the lifting member 210 may be generally in the form of a cover structure, which may include a first cover plate 211 and a first surrounding plate 212. The first surrounding plate 212 may be disposed around the edge of the first cover plate 211, and the first cover plate 211 may be located at the second end 210b of the lifting member. For example, the first end 210a of the lifting member may be the lower end of the lifting member 210 in FIG. 4, and the second end 210b of the lifting member may be the upper end of the lifting member 210 in FIG. 4. The first cover plate 211 and the first surrounding plate 212 may enclose an accommodating space, which may be used to accommodate the lens assembly 21.

[0073] In addition, the lens assembly 21 can be positioned directly opposite the first cover plate 211, which can be made of a transparent material so that ambient light from the outside can enter the lens assembly 21 via the first cover plate 211 of the lifting member 210.

[0074] The direction from the first end 220a of the base to the second end 220b of the base can intersect with the lifting direction X.

[0075] For example, the base 220 may be generally in the form of a cover structure, which may include a second cover plate 221 and a second surrounding plate 222, the second surrounding plate 222 being disposed around the edge of the second cover plate 221. For example, the first end 220a of the base may be the left end of the base 220 in FIG4, and the second end 220b of the base may be the right end of the base 220 in FIG4.

[0076] Furthermore, the first end 220a of the base can be disposed around the lifting member 210, and there is a gap Q between the side wall of the lifting member 210 and the first end 220a of the base. For example, the second cover plate 221 of the base 220 can have a first through hole 223, and the lifting member 210 can pass through the first through hole 223 of the second cover plate 221. Moreover, the side wall of the lifting member 210 can be the outer surface of the first enclosure plate 212 of the lifting member 210, and the lifting member 210 can be clearance-fitted with the first through hole 223 of the second cover plate 221 so that there is a gap Q between the side wall of the lifting member 210 and the first end 220a of the base.

[0077] The first end 220a of the base is rotatable relative to the second end 220b of the base. In some embodiments, the second end 220b of the base can be rotatably connected to the rear cover 14, so that the first end 220a of the base can rotate relative to the second end 220b of the base.

[0078] For example, the lifting mechanism 200 may further include a mounting base 240, which is disposed within the accommodating cavity 15 and connected to the rear cover 14. The second end 220b of the base can be connected to the rear cover 14 via the mounting base 240. For example, the second end 220b of the base and the mounting base 240 can be rotatably connected via a virtual shaft connection. Alternatively, the second end 220b of the base can be rotatably connected to the mounting base 240 via a physical shaft connection. Of course, in some other embodiments, the mounting base 240 may be omitted, and the second end 220b of the base may be directly rotatably connected to the rear cover 14. This application does not specifically limit this aspect.

[0079] Furthermore, the lifting member 210 is movable relative to the second end 220b of the base. In some embodiments, the direction of movement of the lifting member 210 relative to the second end 220b of the base may intersect with the lifting direction X. Specifically, the direction of movement of the lifting member 210 relative to the base 220 may have components of the lifting direction X and the first direction Y; that is, the lifting member 210 may move obliquely upward relative to the base 220.

[0080] For example, the lifting mechanism 200 may include a drive assembly (not shown in the figure) and a linkage assembly 250, wherein the linkage assembly 250 may connect the lifting member 210 and the base 220, and the drive assembly may be connected to the linkage assembly 250. When the drive assembly drives the linkage assembly 250 to move, the linkage assembly 250 drives the lifting member 210 to move, and at the same time, the linkage assembly 250 also drives the base 220 to move.

[0081] Figure 5 is a structural diagram of a lifting mechanism 200 in a retracted state according to an embodiment of this application; Figure 6 is a cross-sectional view of the lifting mechanism 200 in Figure 5 (excluding the mounting base 240) along section line AA. Figure 7 is a structural diagram of a lifting mechanism 200 in a pop-up state according to an embodiment of this application; Figure 8 is a cross-sectional view of the lifting mechanism 200 in Figure 7 (excluding the mounting base 240) along section line BB. The lifting states of the lifting mechanism 200 will be described below with reference to Figures 5, 6, 7, and 8.

[0082] Referring to Figures 5 and 6, when the lifting mechanism 200 is in the retracted state, the first end 220a and the second end 220b of the base are arranged along the first direction Y. In the lifting direction X, the distance between the second end 210b of the lifting member and the second end 220b of the base is the first distance D1.

[0083] Referring to Figure 2, when the lifting mechanism 200 is in the retracted state, the second cover plate 221 of the base 220 can be parallel to the rear cover 14. Specifically, the second cover plate 221 of the base 220 can be flush with the rear cover 14, or it can be located on one side of the rear cover 14 along the lifting direction X. Furthermore, the first cover plate 211 of the lifting member 210 can be parallel to the rear cover 14.

[0084] In this configuration, the first cover plate 211 of the lifting member 210 can be flush with the second cover plate 221 of the base 220. In this case, the distance between the second end 210b of the lifting member and the second end 220b of the base is 0 in the lifting direction X. Alternatively, the first cover plate 211 of the lifting member 210 can also be located on one side of the second cover plate 221 of the base 220 along the lifting direction X. In this case, there can be a small distance between the second end 210b of the lifting member and the second end 220b of the base in the lifting direction X.

[0085] Referring to Figures 7 and 8, when the lifting mechanism 200 is in the pop-out state, the direction from the first end 220a of the base to the second end 220b of the base intersects the lifting direction X and the first direction Y, respectively. In the lifting direction X, the distance between the second end 210b of the lifting member and the second end 220b of the base is the second distance D2, which is greater than the first distance D1.

[0086] Referring to Figure 3, when the lifting mechanism 200 is in the pop-out state, the second cover plate 221 of the base 220 can have an angle with the rear cover 14. For example, the direction from the first end 220a of the base to the second end 220b of the base can be approximately obliquely downward in Figure 8. The first cover plate 211 of the lifting member 210 can have an angle with the second cover plate 221 of the base 220.

[0087] Referring to Figures 2, 6, and 8, during the transition of the lifting mechanism 200 from the retracted state to the extended state, the first end 220a of the base rotates relative to the second end 220b of the base in a direction away from the rear cover 14. For example, the first end 220a of the base rotates clockwise relative to the second end 220b of the base. Furthermore, the second end 210b of the lifting member moves relative to the second end 220b of the base in a direction away from the rear cover 14. For example, the second end 210b of the lifting member moves obliquely upward relative to the second end 220b of the base. Here, the obliquely upward movement can be understood as the lifting direction X tilting towards the first direction Y.

[0088] Referring to Figures 3, 6, and 8, during the transition of the lifting mechanism 200 from the pop-up state to the retracted state, the first end 220a of the base rotates relative to the second end 220b of the base towards the rear cover 14. For example, the first end 220a of the base rotates counterclockwise relative to the second end 220b of the base. Furthermore, the second end 210b of the lifting member moves relative to the second end 220b of the base towards the rear cover 14. For example, the second end 210b of the lifting member moves obliquely downward relative to the second end 220b of the base. Here, oblique downward movement can be understood as moving in the opposite direction to the lifting direction X, tilting in the opposite direction to the first direction Y.

[0089] With the above configuration, when the lifting mechanism 200 is in the retracted state, the distance between the lifting member 210 and the rear cover 14 is small, allowing at least a portion of the camera module to retract into the accommodating cavity, reducing the protrusion of the camera module outside the rear cover 14, which helps to avoid damage to the camera module and improves its reliability. When the lifting mechanism 200 is in the extended state, the distance between the lifting member 210 and the rear cover 14 is large, allowing at least a portion of the camera module to extend out of the accommodating cavity, thereby increasing the available optical space of the camera module and achieving high-quality shooting.

[0090] Furthermore, in this embodiment, the lifting mechanism 200 also includes a sealing element 230, which includes a main body 233, a first sealing ring 231, and a second sealing ring 232. The main body 233 connects the first sealing ring 231 and the second sealing ring 232.

[0091] The first sealing ring 231 is located on one side of the first end 220a of the base along the lifting direction X, and is circumferentially connected to the first end 220a of the base. For example, the first sealing ring 231 is located at the upper end of the first end 220a of the base, and the first sealing ring 231 can be disposed along the edge of the first through hole 223. The shape of the first sealing ring 231 can be correspondingly set according to the shape of the first through hole 223. For example, when the first through hole 223 is a square hole, the shape of the first sealing ring 231 can be a square ring. Alternatively, the shape of the first sealing ring 231 can also be a circular ring, an elliptical ring, etc.

[0092] The second sealing ring 232 is located on one side of the second end 210b of the lifting member along the lifting direction X, and is circumferentially connected to the second end 210b of the lifting member. For example, the second sealing ring 232 is located at the upper end of the second end 210b of the lifting member, and the second sealing ring 232 can be disposed along the edge of the first cover plate 211 of the lifting member 210. The shape of the second sealing ring 232 can be correspondingly set according to the shape of the first cover plate 211. For example, when the first cover plate 211 is a square cover plate, the shape of the second sealing ring 232 can be a square ring. Alternatively, the shape of the second sealing ring 232 can also be a circular ring, an elliptical ring, etc.

[0093] The main body 233 can stretch or contract in the direction from the first sealing ring 231 to the second sealing ring 232, and cover the gap Q between the side wall of the lifting member 210 and the first end 220a of the first base. For example, the main body 233 can be made of an elastic material so that the main body 233 can have a certain elasticity and can undergo elastic deformation of stretching or contraction in the direction from the first sealing ring 231 to the second sealing ring 232.

[0094] Figure 9 is a structural diagram of a sealing element 230 provided in an embodiment of this application when the lifting mechanism 200 is in a retracted state, and Figure 10 is a structural diagram of a sealing element 230 provided in an embodiment of this application when the lifting mechanism 200 is in a pop-up state.

[0095] Referring to Figures 9 and 10, it can be seen that during the transition of the lifting mechanism 200 from the retracted state to the extended state, the main body 233 can be stretched in the direction from the first sealing ring 231 to the second sealing ring 232, thereby increasing the size of the main body 233. Conversely, during the transition of the lifting mechanism 200 from the extended state to the retracted state, the main body 233 can be contracted in the direction from the first sealing ring 231 to the second sealing ring 232, thereby decreasing the size of the main body 233. Here, "the size of the main body 233" can be understood as the cross-sectional dimension of the main body 233 in a plane parallel to the lifting direction X, in the direction from the first sealing ring 231 to the second sealing ring 232.

[0096] With the above configuration, during the transition between the retracted and extended states of the lifting mechanism 200, the first end 220a of the first base drives the first sealing ring 231 to rotate relative to the second end 220b of the base, and the second end 210b of the lifting member drives the second sealing ring 232 to move relative to the second end 220b of the base. When there is relative movement between the first sealing ring 231 and the second sealing ring 232, the main body 233 can stretch or retract in the direction from the first sealing ring 231 to the second sealing ring 232, and shield the gap Q between the first end 220a of the base and the second end 210b of the lifting member, preventing external debris from entering the equipment through this gap Q. Thus, the sealing member 230 can provide dynamic protection for the first end 220a of the base and the second end 210b of the lifting member.

[0097] Furthermore, since the first sealing ring 231 is located at one end of the base 220 along the lifting direction X, and the second sealing ring 232 is located at one end of the lifting member 210 along the lifting direction X, the sealing member 230 is located on the outer surface of the lifting member 210 and the base 220. The sealing member 230, the base 220 and the lifting member 210 can together form the appearance surface of the camera module, which is beneficial to improving the aesthetics of the device.

[0098] In some embodiments, the main body 233, the first sealing ring 231, and the second sealing ring 232 can be an integral structure. For example, the main body 233, the first sealing ring 231, and the second sealing ring 232 can be integrally formed by injection molding. This arrangement helps to improve the connection strength between the main body 233, the first sealing ring 231, and the second sealing ring 232, while also ensuring the sealing performance of the seal 230.

[0099] In some examples, the material of seal 230 may include silicone, polyimide (PI), polyetherimide (PEI), chloroprene rubber (CR), acrylonitrile-butadiene rubber (NBR), ethylene-propylene-diene monomer (EPDM), fluoroelastomer (FKM), polyurethane (PU), polyvinyl chloride (PVC), polyvinyl alcohol (PVA), thermoplastic polyurethanes (TPU), polytetrafluoroethylene (PTFE), expanded polytetrafluoroethylene (ePTFE), polystyrene (PS), polyester (PET), polycarbonate (PC), polyethylene (PE), polypropylene (PP), liquid crystal polymer (LCP), polyetheretherketone (PEK), etc. At least one of polyether ether ketone (PEEK), polyether ketone (PEK-EK), polyethersulfone (PES), or polysulfone (PESU).

[0100] Through the above-described design, the seal 230 possesses high temperature and high humidity resistance, meeting sealing requirements under varying pressure and temperature conditions. This effectively prevents the intrusion of impurities and external contaminants such as liquids, improving the reliability and service life of the seal 230, enhancing its sealing effect, reducing the risk of failure due to dynamic bending in harsh environments such as high temperature and high humidity, and improving the stability and reliability of the camera module in such environments. This, in turn, enhances the stability and reliability of the electronic device. Furthermore, it increases the flexibility in material selection for the seal 230.

[0101] Figure 11 is an enlarged view of the structure at point M in Figure 6. Referring to Figure 11, in some embodiments, the main body 233 may include a plurality of sequentially arranged pleats 235, which may surround the lifting member 210.

[0102] For example, multiple pleats 235 can be arranged sequentially in the direction from the first sealing ring 231 to the second sealing ring 232. The direction from the first sealing ring 231 to the second sealing ring 232 can intersect with the lifting direction X. For instance, within the reference plane containing the lifting direction X and the first direction Y, the cross-sectional shape of the multiple pleats 235 can be approximately wavy.

[0103] Figure 12 is a structural diagram of a plurality of pleats 235 in a compressed state according to an embodiment of the present application; Figure 13 is a structural diagram of a plurality of pleats 235 in a stretched state according to an embodiment of the present application.

[0104] Referring to Figures 12 and 13, exemplarily, the fold 235 may include a first surface 2351 and a second surface 2352 connected together, and the connection end of the first surface 2351 and the second surface 2352 may be located at the turning end 2357 of the fold 235. In the reference plane containing the lifting direction X and the first direction Y, the cross-sectional shape of the turning end 2357 of the fold 235 is not limited in this embodiment. For example, the cross-sectional shape of the turning end 2357 of the fold 235 may be arc-shaped or pointed.

[0105] In some examples, the first surface 2351 and the second surface 2352 have the same shape, and the shapes of the first surface 2351 and the second surface 2352 may be the same as the shape of the first sealing ring 231 or the second sealing ring 232. For example, in an embodiment where both the first sealing ring 231 and the second sealing ring 232 are square rings, the shapes of the first surface 2351 and the second surface 2352 may also be square rings. Of course, in some other examples, the first surface 2351 and the second surface 2352 may also have other shapes, and this application embodiment does not limit this.

[0106] When the lifting mechanism 200 is in the retracted state, a first angle may exist between the first surface 2351 and the second surface 2352. When the lifting mechanism 200 is in the extended state, a second angle may exist between the first surface 2351 and the second surface 2352, and the second angle may be greater than the first angle. It is understood that the above example compares the first surface 2351 and the second surface 2352 at the same location on the main body 233. When the main body 233 is in the extended state, the angle between the first surface 2351 and the second surface 2352 may also be different at different positions on the main body 233, so that different positions on the main body 233 can have different shapes.

[0107] With the above configuration, when the included angle between the first surface 2351 and the second surface 2352 in the fold 235 is small, the fold 235 can be compressed to make the size of the main body 233 smaller; conversely, when the included angle between the first surface 2351 and the second surface 2352 in the fold 235 is large, the fold 235 can be stretched to make the size of the main body 233 larger.

[0108] In summary, the body portion can achieve dimensional changes in the folds 235 through compression and stretching without compressing or stretching the material itself. This allows the body portion provided in this embodiment of the invention to be repeatedly compressed and stretched, which is beneficial for improving the service life of the seal 230.

[0109] In some embodiments, the thickness of the pleat 235 may be less than or equal to the thickness of the first sealing ring 231. Here, the thickness of the pleat 235 can be understood as the size of the pleat 235 in the direction perpendicular to the first surface 2351 or the second surface 2352. The thickness of the first sealing ring 231 can be understood as the size of the first sealing ring 231 in the lifting direction X.

[0110] In some embodiments, the thickness of the pleat 235 may be less than or equal to the thickness of the second sealing ring 232. Here, the thickness of the second sealing ring 232 can be understood as the dimension of the second sealing ring 232 in the lifting direction X.

[0111] When the seal 230 is formed by injection molding, reducing the thickness of the wrinkles 235 helps to shape the wrinkles 235, thereby improving the appearance of the seal 230.

[0112] In this embodiment, reducing the thickness of the pleats 235 also helps to improve the elastic tensile force of the pleats 235. When the main body 233 changes from a contracted state to a stretched state, it helps to increase the speed of the stretching deformation of the main body 233. Furthermore, reducing the thickness of the pleats 235 also helps to improve the elastic recovery force of the pleats 235. When the main body 233 changes from a stretched state to a contracted state, it helps to increase the recovery speed of the main body 233.

[0113] Furthermore, by reducing the thickness of the pleats 235, the number of pleats 235 provided in the main body 233 can be increased within the limited space between the first sealing ring 231 and the second sealing ring 232. This, in turn, helps to further improve the elastic tensile force and elastic recovery force of the main body 233, thereby further improving the tensile deformation speed and elastic recovery speed of the main body 233. In summary, this is beneficial to further improve the aesthetic appearance of the equipment.

[0114] In some embodiments, the plurality of sequentially arranged pleats 235 may include a first pleat 235a and a second pleat 235b. When the lifting mechanism 200 is in the retracted state, the first pleat 235a is closer to the first sealing ring 231 than the second pleat 235b. For example, the first pleat 235a in FIG11 may be closer to the lower end in FIG11 than the second pleat 235b.

[0115] When the lifting mechanism 200 is in the retracted state, the closed shape enclosed by the turning end 2357 of the first fold 235a and the closed shape enclosed by the turning end 2357 of the second fold 235b can be the same, and the area of ​​the closed shape enclosed by the turning end 2357 of the first fold 235a can be greater than the area of ​​the closed shape enclosed by the turning end 2357 of the second fold 235b.

[0116] For example, in the plurality of pleats 235, the closed shape enclosed by the turning ends 2357 of each pleat 235 can be identical. Among the plurality of pleats 235, the closed shape enclosed by the pleats 235 closer to the second sealing ring 232 is smaller, and the closed shape enclosed by the pleats 235 closer to the first sealing ring 231 is larger. Furthermore, in the direction from the second sealing ring 232 to the first sealing ring 231, the area of ​​the closed shape enclosed by the turning ends 2357 of the plurality of pleats 235 can gradually increase.

[0117] Correspondingly, the area of ​​the closed shape enclosed by the edge of the second end 210b of the lifting component is smaller than the area of ​​the closed shape enclosed by the through hole of the first end 220a of the base. This arrangement helps the main body 233 better conceal the gap Q between the base 220 and the lifting component 210, further improving the aesthetic appearance of the equipment.

[0118] Furthermore, during the transition between the stretched and contracted states, the main body 233 is designed to ensure that the multiple folds 235 within it are subjected to uniform force, preventing the folds 235 from being excessively stretched or compressed, thereby improving the reliability of the main body 233.

[0119] Referring again to Figure 11, the main body 233 may further include a curved structure 236, which may surround the lifting member 210. The first end 236a of the curved structure may be connected to the second sealing ring 232, and the second end 236b of the curved structure may be connected to the pleat 235. The thickness of the first end 236a of the curved structure may be greater than the thickness of the second end 236b of the curved structure.

[0120] For example, the second end 236b of the bending structure 236 can be bent towards the first base 220 relative to the first end 236a of the bending structure. The thickness of the bending structure can gradually decrease in the direction from the first end 236a to the second end 236b.

[0121] Because the connection between the second sealing ring 232 and the pleat 235 requires multiple bends, fatigue failure is likely to occur. By providing a bending structure 236 between the second sealing ring 232 and the pleat 235, the connection between the main body 233 and the second sealing ring 232 can be strengthened, which helps to improve the reliability of the seal 230 and extend its service life.

[0122] Of course, in some other embodiments, the curved structure 236 may also be disposed between the first sealing ring 231 and the pleat 235. For example, the first end 236a of the curved structure may also be connected to the first sealing ring 231. The second end 236b of the curved structure may be bent relative to the first end 236a toward the second end 210b of the lifting member.

[0123] Similarly, by providing a bending structure 236 between the first sealing ring 231 and the pleat 235, the connection between the main body 233 and the first sealing ring 231 can be strengthened, which is beneficial to improving the reliability of the seal 230 and extending the service life of the seal 230.

[0124] In some embodiments, when the lifting mechanism 200 is in a retracted state, the distance between the first end 2338 of the main body and the second end 220b of the base is greater than the distance between the second end 2339 of the main body and the second end 220b of the base.

[0125] As shown in Figure 9, when the lifting mechanism 200 is in the retracted state, the shape of the orthographic projection of the main body 233 onto a plane perpendicular to the lifting direction X can be approximately a square ring. For example, the main body 233 may include a first sub-part 233a, a second sub-part 233b, a third sub-part 233c, and a fourth sub-part 233d; wherein the first sub-part 233a and the second sub-part 233b can be arranged along the first direction Y, the third sub-part 233c can be connected between the first sub-part 233a and the second sub-part 233b, and the fourth sub-part 233d can be connected between the first sub-part 233a and the second sub-part 233b, and the first sub-part 233a, the third sub-part 233c, the second sub-part 233b, and the fourth sub-part 233d can be connected end to end in sequence. The first end 2338 of the main body may include the first sub-part 233a, and the second end 2339 of the main body may include the second sub-part 233b.

[0126] Of course, in some other embodiments, the shape of the orthographic projection of the main body 233 onto a plane perpendicular to the lifting direction X can be approximately circular. The first end 2338 and the second end 2339 of the main body can be symmetrically arranged relative to the center of the circular ring; that is, a straight line pointing from the first end 2338 to the second end 2339 of the main body can pass through the center of the circular ring.

[0127] Figure 14 is a sectional view of the seal in Figure 9 along the CC section line; Figure 15 is a sectional view of the seal in Figure 10 along the DD section line.

[0128] Referring to Figures 14 and 15, when the lifting mechanism 200 is in the retracted state, in the lifting direction X, the dimension H1 of the first end 2338 of the main body is equal to the dimension H3 of the second end 2339 of the main body. When the lifting mechanism 200 is in the extended state, in the lifting direction X, the dimension H2 of the first end 2338 of the main body is smaller than the dimension H4 of the second end 2339 of the main body.

[0129] Here, in the lifting direction X, the dimension of the first end 2338 of the main body can be understood as the dimension of the first sub-part 233a in the lifting direction X; in the lifting direction X, the dimension of the second end 2339 of the main body can be understood as the dimension of the second sub-part 233b in the lifting direction X.

[0130] As described in the above embodiments, when the lifting mechanism 200 is in the retracted state, the first cover plate 211 of the lifting member 210 can be parallel to the second cover plate 221 of the base 220. When the first cover plate 211 and the second cover plate 221 are flush, the first sealing ring 231 and the second sealing ring 232 can be flush, and in the lifting direction X, the dimensions of the first sub-part 233a and the second sub-part 233b can be equal. When the first cover plate 211 is located on one side of the second cover plate 221 along the lifting direction X, the second sealing ring 232 can be located on one side of the first sealing ring 231 along the lifting direction X, and in the lifting direction X, the dimensions of the first sub-part 233a and the second sub-part 233b can be equal.

[0131] When the lifting mechanism 200 is in the pop-out state, the first end 220a of the base is further away from the rear cover than the second end 220b of the base, and the plane where the first cover plate 211 of the lifting member 210 is located can intersect with the plane where the second cover plate 221 of the base 220 is located. In the lifting direction X, the size of the first sub-part 233a can be smaller than the size of the second sub-part 233b.

[0132] With the above settings, when the lifting mechanism 200 is in the retracted or extended state, the first end 2338 of the main body can be deformed by contraction or stretching to shield the gap Q on one side of the lifting member 210 and the base 220. The second end 2339 of the main body can be deformed by contraction or stretching to shield the gap Q on the other side of the lifting member 210 and the base 220, preventing external debris from entering the equipment through the gap Q. Thus, the seal 230 can achieve dynamic protection for the first end 220a of the base and the second end 210b of the lifting member.

[0133] Furthermore, in some embodiments, when the lifting mechanism 200 is in the retracted state, the distance between the orthographic projections of the first sealing ring 231 and the second sealing ring 232 onto the reference plane along the lifting direction X is equal everywhere along the first direction Y. Here, the reference plane is the plane containing the lifting direction X and the first direction Y. Correspondingly, the dimensions of at least a portion of the third sub-part 233c or at least a portion of the fourth sub-part 233d along the lifting direction X can be equal everywhere along the first direction Y.

[0134] When the lifting mechanism 200 is in the pop-out state, the distance between the orthographic projections of the first sealing ring 231 and the second sealing ring 232 on the reference plane along the lifting direction X gradually increases in the first direction Y. Correspondingly, the dimensions of at least a portion of the third sub-part 233c or at least a portion of the fourth sub-part 233d in the lifting direction X can gradually increase in the first direction Y.

[0135] The above settings help to further improve the shielding effect of the seal 230 on the lifting component 210 and the base 220, further improve the dynamic protection effect of the lifting mechanism 200, and improve the reliability of the camera module.

[0136] In some embodiments, when the lifting mechanism 200 is in a retracted state, the size of the first end 2338 of the main body in the lifting direction X is a first size H1; when the lifting mechanism 200 is in a pop-out state, the size of the first end 2338 of the main body in the lifting direction X is a second size H2, and the second size H2 is greater than the first size H1.

[0137] For example, during the transition from the retracted state to the pop-out state, the displacement of the lifting member 210 relative to the second end 220b of the base in the lifting direction X is greater than the displacement of the first end 220a of the base relative to the second end 220b of the base in the lifting direction X, thereby increasing the distance between the first cover plate 211 and the second cover plate 221.

[0138] With the above settings, during the transition from the retracted state to the extended state, the first end 2338 of the main body of the lifting mechanism 200 is stretched in the lifting direction X, and during the transition from the extended state to the retracted state, the first end 2338 of the main body is compressed in the lifting direction X. Thus, the first end 2338 of the main body shields the gap Q between the first end 220a of the base and the second end 210b of the lifting component, thereby achieving dynamic protection of the lifting mechanism 200.

[0139] In some embodiments, when the lifting mechanism 200 is in a retracted state, in the first direction Y, the size of the first end 2338 of the main body is the third size L3, and the size of the second end 2339 of the main body is the fourth size L4; when the lifting mechanism 200 is in a popped-out state, in the first direction Y, the size of the first end 2338 of the main body is the fifth size L5, which is greater than the third size L3, and the size of the second end 2339 of the main body is the sixth size L6, which is less than the fourth size L4.

[0140] For example, during the transition from a retracted state to an extended state, the lifting mechanism 200 moves obliquely upward relative to the second end 220b of the base, and the lifting member 210 has a displacement in the first direction Y relative to the second end 220b of the base. The displacement of the lifting member 210 in the first direction Y relative to the second end 220b of the base is greater than the displacement of the first end 220a of the base relative to the base 220 in the first direction Y.

[0141] With the above configuration, during the transition from the retracted state to the extended state, the first end 2338 of the main body is stretched in the first direction Y, and the second end 2339 of the main body is retracted in the first direction Y. During the transition from the extended state to the retracted state, the first end 2338 of the main body is retracted in the first direction Y, and the second end 2339 of the main body is stretched in the first direction Y. The first end 2338 and the second end 2339 of the main body thus shield the gap Q between the first end 220a of the base and the second end 210b of the lifting component, thereby achieving dynamic protection of the lifting mechanism 200.

[0142] In some embodiments, the lifting mechanism 200 may further include a first adhesive layer 260, which may be connected between the first sealing ring 231 and the first end 220a of the base. The first adhesive layer 260 may be a dotted adhesive layer or a backing adhesive layer. This arrangement connects the first sealing ring 231 and the base 220, improving the ease of connection between them.

[0143] Referring again to Figure 11, in some embodiments, the lifting mechanism 200 may further include a second adhesive layer 270, which may be connected between the second sealing ring 232 and the second end 210b of the lifting member. The second adhesive layer 270 may be a dotted adhesive layer or a backing adhesive layer. This arrangement connects the second sealing ring 232 and the lifting member 210, improving the ease of connection between them.

[0144] Referring to Figures 4, 6, and 8, the linkage component 250 provided in this embodiment may include a first link 251. The first end 251a of the first link is rotatable relative to the second end 251b of the first link, and the first end 251a of the first link is slidably connected to the first end 210a of the lifting member.

[0145] For example, the second end 251b of the first link can be connected to a drive assembly. For instance, the drive assembly may include a drive motor, the output shaft of which can be connected to the second end 251b of the first link. The drive motor can drive the first link 251 to rotate, so that the first end 251a of the first link can rotate relative to the second end 251b of the first link.

[0146] In some embodiments, the first end 251a of the first connecting rod can be slidably connected to the first end 210a of the lifting member via a first groove 215 and a first slider 2512. The second end 251b of the first connecting rod includes the first groove 215, and the first end 210a of the lifting member includes the first slider 2512. When the lifting mechanism 200 is in the retracted state, the extending direction of the first groove 215 is perpendicular to the lifting direction X.

[0147] For example, the first slide 215 can be generally strip-shaped. When the lifting mechanism 200 is in the retracted state, the extension direction of the strip structure can be parallel to the first direction Y and perpendicular to the lifting direction X. The first end and the second end of the first slide 215 can be arranged along the first direction Y, and the first end of the first slide 215 is farther away from the second end 251b of the first connecting rod than the second end of the first slide 215.

[0148] With the above settings, during the transition of the lifting mechanism 200 from the retracted state to the pop-out state, the first end 251a of the first connecting rod rotates clockwise relative to the second end 251b of the first connecting rod, and the first slider 2512 can move relative to the first slide groove 215, and the direction of movement is from the first end of the first slide groove 215 to the second end of the first slide groove 215, so that the first end 251a of the first connecting rod can drive the lifting member 210 to move, and the lifting member 210 has lifting direction X and first direction Y movement components.

[0149] Conversely, during the transition of the lifting mechanism 200 from the pop-up state to the retracted state, the first end 251a of the first link rotates counterclockwise relative to the second end 251b of the first link, and the first slider 2512 can move relative to the first slide groove 215 in the direction from the second end of the first slide groove 215 to the first end of the first slide groove 215, so that the first end 251a of the first link can drive the lifting member 210 to move, and the lifting member 210 has a movement component opposite to the lifting direction X and a movement component opposite to the first direction Y.

[0150] Alternatively, in some other embodiments, the second end 251b of the first connecting rod includes a first slider 2512, and the first end 210a of the lifting member includes a first groove 215, so that the first connecting rod 251 and the first end 210a of the lifting member can be slidably connected through the first groove 215 and the first slider 2512. Of course, the first connecting rod 251 and the first end 210a of the lifting member can also be slidably connected using other connection methods, and this application embodiment does not limit this.

[0151] The linkage component 250 provided in this embodiment may further include a second link 252. The first end 252a of the second link may be rotatably connected to the first link 251, and the second end 252b of the second link may be rotatably connected to the base 220.

[0152] With the above settings, during the transition of the lifting mechanism 200 from the retracted state to the extended state, the first end 251a of the first link rotates clockwise relative to the second end 251b of the first link, so that the first link 251 can drive the first end 220a of the base to rotate relative to the second end 220b of the base through the second link 252. The rotation direction of the first end 220a of the base relative to the second end 220b of the base can be clockwise.

[0153] Conversely, during the transition of the lifting mechanism 200 from the pop-out state to the retracted state, the first end 251a of the first link rotates counterclockwise relative to the second end 251b of the first link, so that the first link 251 can drive the first end 220a of the base to rotate relative to the second end 220b of the base through the second link 252. The rotation direction of the first end 220a of the base relative to the second end 220b of the base can be counterclockwise.

[0154] In summary, by setting the first link 251 and the second link 252 in the linkage component 250, the linkage between the base 220 and the lifting component 210 can be realized.

[0155] Furthermore, by way of example, the first end 252a of the second link can be connected between the first end 251a and the second end 251b of the first link. The second end 252b of the second link can be connected between the first end 220a and the second end 220b of the base.

[0156] With the above settings, during the transition of the lifting mechanism 200 from the retracted state to the extended state, the displacement of the lifting member 210 relative to the second end 220b of the base in the lifting direction X is greater than the displacement of the first end 220a of the base relative to the second end 220b of the base in the lifting direction X; the displacement of the lifting member 210 relative to the second end 220b of the base in the first direction Y is greater than the displacement of the first end 220a of the base relative to the base 220 in the first direction Y.

[0157] In this embodiment, multiple linkage components 250 can be provided between the lifting member 210 and the base 220. For example, the number of linkage components 250 in FIG4 can be two. In some embodiments, the structures of different linkage components 250 can be the same, or the structures of different linkage components 250 can be different.

[0158] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
