Lifting mechanism, camera device and electronic equipment

[0001] The present application claims priority to the Chinese patent application No. 202410735832.1, filed on June 6, 2024, and entitled "Lifting mechanism, camera device and electronic equipment", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of terminal equipment, in particular to a lifting mechanism, a camera device and an electronic equipment. BACKGROUND

[0003] With the maturity of the camera function of electronic equipment, users' demand for long-focus shooting is also increasing, for example, electronic equipment with camera function such as mobile phones and tablets usually need long-focus shooting function. For the increasingly thin form of electronic equipment, the integration of long-focus lenses cannot be separated from a telescopic lifting mechanism. How to achieve fast driving of the lifting mechanism to improve user experience is a problem to be solved at present. SUMMARY

[0004] The present application provides a lifting mechanism, a camera device and an electronic equipment. The lifting mechanism can include two motors. In the present application, a double-motor driving lifting member lifting scheme is adopted, which has greater driving force and higher driving efficiency, and is conducive to realizing faster lifting process of the lifting mechanism.

[0005] In a first aspect, the present application provides a lifting mechanism applied to a camera device including a camera module. The lifting mechanism includes a base, a lifting member mounted on the base, a driving assembly and a transmission assembly. The transmission assembly connects the driving assembly and the lifting member. The driving assembly can drive the lifting member to lift relative to the base through the transmission assembly. The driving assembly includes two driving groups. Each driving group includes a motor, a worm and a turbine. The motor is mounted on the base. The worm is fixedly connected to the output shaft of the motor. The turbine is rotatably connected to the base. The turbine is engaged with the worm and is transmissionally connected to the transmission assembly.

[0006] In the present application, the motors in the drive groups can work for the lifting mechanism to drive the lifting member to lift relative to the base. By arranging two drive groups, the driving force is larger and the driving efficiency is higher, which is conducive to achieving a faster lifting process of the lifting member. In addition, the motor is engaged with the worm through the turbine, and the turbine is drivingly connected with the transmission assembly, so as to realize the transmission of the motor energy. The turbine and worm transmission structure is simple and compact, which reduces the number of structural members or components for transmission between the motor and the transmission assembly, and the engagement between the turbine and the worm is continuous, and the transmission is also relatively stable, which is conducive to achieving a stable and fast lifting process of the lifting member. In other implementation manners, the turbine and worm can also be used for transmission between the motor and the transmission assembly, and other ways such as multi-link cooperation or multi-gear engagement can also be used.

[0007] In some possible implementation manners, each drive group further comprises an elastic member connected between the turbine and the transmission assembly; the lifting mechanism has a retracted state and an extended state, and when the lifting mechanism changes from the retracted state to the extended state, the motor drives the turbine to rotate in a first rotation direction, and the turbine drives the transmission assembly to move through the elastic member to lift the lifting member.

[0008] In the present implementation manner, the two ends of the elastic member can be respectively connected to the turbine and the transmission assembly, and the first rotation direction can be the normal direction of the elastic member towards the turbine. When the motor drives the turbine to rotate in the first rotation direction, the elastic member is further compressed, and the elastic member can drive the transmission assembly to rotate through the restoring force of deformation, thereby lifting the lifting member.

[0009] In some possible implementation manners, when the lifting mechanism is in the extended state and the lifting member is subjected to external pressure, the lifting member descends, the transmission assembly moves, and the elastic member deforms.

[0010] The lifting member can descend after being subjected to external pressure, and the elastic member can buffer the pressure by deformation to avoid hard impact on the lifting member. In addition, after the pressure on the lifting member is removed, the elastic member can drive the transmission assembly to rotate through the restoring force of deformation to drive the lifting member to return to the extended state.

[0011] The external pressure can come from the falling of the electronic device, the impact of the electronic device on the external environment, the extrusion of the electronic device on the external environment, etc.

[0012] In some possible implementation manners, when the lifting mechanism changes from the extended state to the retracted state, the motor drives the turbine to rotate in a second rotation direction opposite to the first rotation direction, and the turbine contacts and drives the transmission assembly to move to lower the lifting member.

[0013] In the implementation, the turbine can have a gear face, the turbine can contact and push the transmission assembly to move through the gear face, and the second rotation direction can be a normal direction of the gear face of the turbine towards the first rotating part. The force can be transmitted between the turbine and the transmission assembly through the surface contact, the structure for transmission between the turbine and the transmission assembly can be saved, and the reliability of the transmission connection between the turbine and the transmission assembly can be improved. The gear face of the turbine can be attached to the transmission assembly or not completely attached to the transmission assembly, the force can be transmitted between the turbine and the transmission assembly through the line-surface contact, and the application does not limit this.

[0014] In some possible implementation, the elastic member is a torsion spring; the central axis of the two elastic members coincides with the rotation axis of the two turbines relative to the base, and the two elastic members are located between the two turbines; each elastic member includes a first end and a second end, the first end of the elastic member is connected to the turbine, the second ends of the two elastic members are oppositely arranged and are both connected to the transmission assembly, and the side of each turbine away from the elastic member is provided with a gear face, and the gear face is connected to the transmission assembly.

[0015] The central axis of the two elastic members coincides with the rotation axis of the two turbines relative to the base, which can avoid additional energy loss between the elastic member and the turbine due to the connection, and effectively improve the transmission efficiency of the motor.

[0016] In some possible implementation, the driving assembly further includes a connecting member, the connecting member is connected between the second ends of the two elastic members, and the two elastic members and the connecting member are an integrally formed structure.

[0017] The second ends of the two elastic members are both connected to the transmission assembly, the connecting member is connected between the second ends of the two elastic members and is connected to the transmission assembly, the two elastic members can apply a force to the transmission assembly (for example, a short supporting rod) through the connecting member, which is beneficial to improve the transmission efficiency and reliability of the elastic member driving the transmission assembly (for example, a short supporting rod) to move, and can also reduce the adverse effects of stress concentration on the service life of the elastic member and the transmission assembly (for example, a short supporting rod).

[0018] The two elastic members and the connecting member can be an integrally formed structure, which is beneficial to increase the structural strength and stability of the structure formed by the two elastic members and the connecting member. In other implementations, the two elastic members and the connecting member can also be an integrated structure formed by assembly, and the application does not limit this.

[0019] In some possible implementation manners, the output shaft of the motor is inserted into the base and can rotate relative to the base, the worm is sleeved outside the output shaft of the motor, and the extension direction of the output shaft of the motor is perpendicular to the rotation axis of the turbine relative to the base. The output shaft of the motor is inserted into the base, and the base can support the output shaft of the motor, thereby facilitating improvement of the reliability and stability of the connection structure of the driving assembly and the base.

[0020] In addition, in the implementation manners of the present application, during the process in which the driving assembly drives the lifting piece to lift relative to the base, when the motor is working, the output shaft of the motor can drive the worm sleeved thereon to rotate, thereby driving the turbine engaged with the worm to rotate, so that the transmission assembly in transmission connection with the turbine and the lifting piece in transmission connection with the transmission assembly are forced to move. In the implementation manners of the present application, by setting the extension direction of the output shaft of the worm to be perpendicular to the rotation axis of the turbine relative to the base, the energy loss caused by the connection in the lifting mechanism can be reduced, and the transmission efficiency of the motor can be effectively improved.

[0021] In some possible implementation manners, the two driving groups are symmetrical structures, that is, the two elastic pieces, the two turbines, the two motors and the two worms can be symmetrical structures. In other implementation manners, the two driving groups can also have other arrangement manners, for example, a partial symmetrical structure or an array structure, which are not limited in the present application. When the two driving groups are in a partial symmetrical structure, the motors and the worms of the two driving groups are of the same structure, the incomplete tooth portions of the two turbines are of the same structure, and the remaining portions are of a symmetrical structure.

[0022] By setting the two driving groups to be symmetrical structures, the synchronism of the working of the two driving groups can be further improved, and the driving efficiency can be improved.

[0023] In some possible implementation manners, the base has a first fixing portion and a second fixing portion which are spaced apart in a first direction;

[0024] The transmission assembly comprises:

[0025] The two long rods are arranged in a second direction and are located on two sides of the lifting piece respectively, the second direction intersects the first direction, the first end of the long rod is rotationally connected to the first fixing portion, the second end of the long rod is rotationally connected to the first end of the lifting piece, and the long rod further comprises an adapter portion which is located between the first end of the long rod and the second end of the long rod;

[0026] The two short rods are located between the two long rods and are oppositely and spaced apart along the second direction, the short rod comprises a first rotating portion, a second rotating portion and a third rotating portion, the first rotating portion is rotationally connected to the second fixing portion, the third rotating portion is slidingly connected or rotationally connected to the second end of the lifting piece, and the second end of the lifting piece is closer to the first end of the long rod relative to the first end of the lifting piece; and

[0027] Two connecting rods, one connecting rod corresponding to one long rod and one short rod, the first rotating end of the connecting rod is rotatably connected to the adapter, and the second rotating end of the connecting rod is rotatably connected to the second rotating part;

[0028] The driving assembly is arranged close to the first end of the long rod relative to the second end of the long rod, and the two turbines are respectively in transmission connection with the two short rods. When the turbines rotate, the short rods move under force, and the short rods and the long rod jointly drive the lifting member to lift relative to the base.

[0029] The part between the first fixed part and the second fixed part of the base can be regarded as a fixed rod formed by a part of the base. The long rod can include a fixedly connected first segment and a second segment. The first segment of the long rod is a line connecting the rotating connection center of the first end of the long rod and the first fixed part, and the rotating connection center of the adapter and the first end of the connecting rod. The second segment of the long rod is a line connecting the rotating connection center of the adapter and the first end of the connecting rod, and the rotating connection center of the second end of the long rod and the first end of the lifting member. The short rod can include a fixedly connected first segment and a second segment. The first segment of the short rod is a line connecting the rotating connection center of the first rotating part and the second fixed part, and the rotating center of the third rotating part. The second segment of the short rod is a line connecting the rotating center of the third rotating part and the rotating connection center of the second rotating part and the second end of the lifting member.

[0030] In the present implementation, the fixed rod, the first segment of the long rod, the connecting rod and the first segment of the short rod are sequentially and rotatably connected end to end, which can form a four-bar linkage mechanism. When the short rod is under force, the second segment of the long rod and the second segment of the short rod can also lift together with the movement of the four-bar linkage mechanism, thereby driving the lifting member to lift together.

[0031] In the present implementation, by arranging the four-bar linkage mechanism, the short rod, the long rod and the connecting rod in the four-bar linkage mechanism are in transmission connection with each other. When the short rod is under force, the force and movement of the short rod are transmitted to the long rod through the connecting rod, so that the short rod and the long rod move together, thereby the driving assembly can drive the four-bar linkage mechanism to move, so as to realize the lifting of the first end and the second end of the lifting member together, realize the conversion of the extended state and the retracted state of the lifting mechanism, and the four-bar linkage mechanism can improve the extension and retraction smoothness of the lifting mechanism. In addition, compared with the driving scheme in which the driving assembly needs to drive the two ends of the lifting member to move respectively to lift the lifting member relative to the base when the lifting mechanism does not form a four-bar linkage mechanism, the lifting mechanism provided by the present application is more labor-saving, convenient, simple in structure and higher in reliability.

[0032] In some possible implementations, the transmission assembly further includes a short support rod connected between the first rotating parts of the two short rods;

[0033] The two turbines are located between the two short rods, and the two turbines drive the two short rods to move by pushing the short support rod, so as to drive the lifting member to ascend;

[0034] The two turbines respectively drive the two short rods to move to drive the lifting member to descend.

[0035] In the present implementation, the first rotating part of the two short rods is fixedly connected through the short supporting rod, so that the third rotating part of the short rod slidingly connected to the two sides of the second end of the lifting member can move synchronously, and the lifting member is balanced in ascending and descending at the first side and the second side of the second end.

[0036] In some possible implementation, the transmission assembly further comprises a first rotating shaft, the first rotating part of the short rod is provided with a first rotating hole, the turbine is provided with a first shaft hole, and the second fixed part is provided with a first rotating shaft hole, and the first rotating shaft is arranged in the first rotating hole, the first shaft hole and the first rotating shaft hole.

[0037] In the present implementation, the first rotating shaft can pass through the first rotating part of the short rod, the turbine, the second fixed part of the base and the elastic member, so as to mount the turbine, the short rod and the elastic member on the base. At this time, the driving assembly can connect the base and the transmission assembly through the first rotating shaft, and has high connection reliability and stability. In the present implementation, the first rotating shaft is arranged in the first rotating hole of the first rotating part, the first shaft hole of the turbine and the first rotating shaft hole of the second fixed part. At this time, the rotating axis of the turbine relative to the base, the rotating axis of the short rod relative to the base and the central axis of the first rotating shaft coincide, that is, the turbine and the short rod can be regarded as rotating relative to the base with the central axis of the first rotating shaft as the rotating axis.

[0038] In some possible implementation, the turbine is provided with a containing groove, the containing groove is communicated with the first shaft hole, and the second fixed part is at least partially located in the containing groove. In the present implementation, the second fixed part of the base can be at least partially located in the containing groove of the turbine, and the two can be in a clamped state, so as to improve the connection reliability and structural stability of the turbine and the base, and the arrangement structure of the turbine and the base is compact, which improves the space utilization of the lifting mechanism and is beneficial to the miniaturization of the lifting mechanism.

[0039] In some possible implementation, each driving assembly further comprises an elastic member, and the elastic member is connected between the first rotating part and the turbine.

[0040] In the ascending process of the lifting member, the turbine drives the first rotating part to move through the elastic member, and in the descending process of the lifting member, the turbine directly drives the first rotating part to move.

[0041] In the present implementation, during the lifting of the lifting member, the elastic member can be further compressed, and the restoring force of the deformation of the elastic member can drive the first rotating part to move, thereby driving the four-bar linkage mechanism to move, so that the lifting member is lifted; during the lowering of the lifting member, the turbine can directly contact and push the first rotating part, thereby driving the four-bar linkage mechanism to move, so that the lifting member is lowered. During the lowering of the lifting member, the deformation and deformation recovery of the elastic member are not required to transmit force, so that the transmission speed of force during the lowering is fast, which is beneficial to the rapid lowering of the lifting member.

[0042] In some possible implementations, each driving group further includes an elastic member, the central axis of the two elastic members coincides with the rotating axis of the two turbines relative to the base, and the two elastic members are located between the two turbines; each elastic member includes a first end and a second end, the first end of the elastic member is connected to the turbine, the second ends of the two elastic members are oppositely arranged and are both connected to the short support rod, the turbine opposite to the elastic member is provided with a blocking surface, and the blocking surface is connected to the first rotating part.

[0043] When the turbine rotates in a direction (i.e., a first rotating direction) in which the turbine presses against the first end of the elastic member, the second end of the elastic member also rotates and pushes the short support rod to rotate, so as to drive the transmission assembly to move, thereby achieving the transmission connection between the turbine and the transmission assembly.

[0044] The blocking surface of the turbine can contact the first rotating part of the short rod. When the turbine rotates in a direction (i.e., a second rotating direction) in which the turbine presses against the first rotating part, the short rod is pushed to rotate, so as to drive the transmission assembly to move, thereby achieving the transmission connection between the turbine and the transmission assembly.

[0045] In some possible implementations, the lifting member is in an initial position relative to the base in the retracted state; the lifting member is lifted to an extended position relative to the base in the extended state, and the axis of the lifting member in the initial position coincides with the axis of the lifting member in the extended position.

[0046] In the present implementation, the axis of the lifting member coincides in the initial position and the extended position, so that the relative position of the lifting member and the base in the initial position and the extended position has no offset in the direction perpendicular to the optical axis of the lifting member, the optical axis of the lifting member can be kept from being offset, and thus the light collection quality of the camera module located in the inner space of the lifting member is ensured, so as to ensure the image collection quality of the camera device.

[0047] In some possible implementations, the base has a first limiting surface, the first limiting surface is arranged towards the bottom side of the base, and the second end of the long rod abuts against the first limiting surface when the lifting member is in the extended state; or, the base has a second limiting surface, the second limiting surface is arranged towards the top side of the base, and the lifting member abuts against the second limiting surface in the retracted state.

[0048] In the implementation of the present application, when the lifting member is converted from the retracted state to the extended state, the first limiting surface can limit the long rod, preventing the lifting member from continuing to rise, so as to avoid overextension of the lifting member and ensure that the extension size of the lifting member is consistent each time, thereby improving the stability of the electronic device during shooting. The first limiting surface is a surface formed by the existing structure of the lifting mechanism. Compared with adding other structures to achieve limiting, the lifting mechanism in the implementation of the present application has low cost and high space utilization.

[0049] In the implementation of the present application, when the lifting member is converted from the extended state to the retracted state, the second limiting surface can limit the lifting member, preventing the lifting member from continuing to descend, so as to avoid the lifting member from colliding with other components inside the electronic device due to over-retraction. In addition, since the lifting member is in the retracted state when the camera device is not shooting, the second limiting surface can support the lifting member, thereby maintaining the structural stability of the lifting mechanism as a whole. The second limiting surface is a surface formed by the existing structure of the base. Compared with adding other structures in the base to achieve the limiting function, the lifting mechanism in the implementation of the present application has low cost and high space utilization.

[0050] In some possible implementations, the periphery of the lifting member is provided with a first avoiding groove, and the bottom wall of the first avoiding groove is arranged to face the bottom side of the lifting member. The part of the base structure is located in the first avoiding groove, and the bottom wall of the first avoiding groove abuts against the second limiting surface in the retracted state.

[0051] By arranging the part of the base structure in the first avoiding groove, the compactness of the arrangement of the lifting member and the base can be improved, and the internal space of the lifting mechanism can be fully utilized, thereby realizing miniaturization of the lifting mechanism.

[0052] In some possible implementations, the lifting mechanism further includes a detection assembly, the detection assembly including a position sensor and a magnetic member. The magnetic member is mounted to the lifting member, and the position sensor is mounted to the base. The position sensor is located in the magnetic field generated by the magnetic member. The position sensor is configured to detect the magnetic flux of the surrounding magnetic field when the lifting member moves. The position sensor can be one or more of a Hall sensor, a tunnel magnetoresistance sensor, and a giant magnetoresistance sensor. In other implementations, the magnetic member can be fixed to the base, and the position sensor can be fixed to the lifting member. The present application does not limit this.

[0053] In a second aspect, the present application also provides a camera device. The camera device includes a camera module and the lifting mechanism of any one of the above. The camera module is mounted to the lifting mechanism.

[0054] In a third aspect, the present application also provides an electronic device. The electronic device includes a shell and the camera device of any one of the above. The shell is provided with a through hole. The camera device is mounted in the shell, and the lifting member of the lifting mechanism of the camera device is exposed to the through hole.

[0055] The lifting member of the lifting mechanism can be lifted out of the through hole of the camera decoration piece to a protruding position, so that the height of the internal space of the lifting mechanism is increased to allow the lens or part of the lens of the camera module to move away from the photosensitive element to increase the distance between the lens or part of the lens and the photosensitive element, increase the focal length of the shooting, and enable the electronic device to realize long-focus shooting to improve the shooting effect. In addition, since the lifting member can protrude out of the through hole, the light entrance surface of the camera device protrudes from the camera decoration piece and the cover plate, reducing light obstruction and improving the light entrance amount of the camera device and improving the shooting quality. The top side of the lifting member can be light-transmissive to serve as the light entrance surface of the camera device. After shooting is completed, the lifting member can be lowered back to the initial position to reduce the overall thickness of the camera device, and more parts of the lifting member are located in the internal space of the lifting mechanism, which is conducive to protecting the lifting member.

[0056] In the present implementation, the lifting member in the lifting mechanism is subjected to a greater driving force and has a higher driving efficiency, has a fast, reliable and smooth lifting process, and improves the user experience when the user uses the electronic device.

The camera module 20 can include a lens 201 and a photosensitive element 202, and the lens 201 and the photosensitive element 202 are arranged in a spaced manner.

[0134] In the present embodiment, the lifting piece 2 of the lifting mechanism 10 can be lifted to the extended position by the through hole 3004 of the camera decoration piece 3003, so that the height of the internal space of the lifting mechanism 10 is increased, to allow the lens 201 or part of the lens 201 of the camera module 20 to move away from the photosensitive element 202, to increase the distance between the lens 201 or part of the lens 201 and the photosensitive element 202, increase the focal length of the shooting, facilitate the focusing and / or focusing of the electronic device 1000, for example, the electronic device 1000 can realize long-focus shooting, to improve the shooting effect. In addition, since the lifting piece 2 can be extended from the through hole 3004, so that the light entrance surface of the camera device 100 protrudes from the camera decoration piece 3003 and the cover plate 3001, reducing the light shielding, which is beneficial to improve the light entrance amount of the camera device 100 and improve the shooting quality. The top side of the lifting piece 2 can be light-transmitting, to serve as the light entrance surface of the camera device 100.

[0135] After the shooting is completed, the lifting piece 2 can be lowered back to the initial position, reducing the overall thickness of the camera device 100, which is conducive to reducing the overall thickness of the electronic device 1000, and can make more parts of the lifting piece 2 located in the internal space of the lifting mechanism 10, which is conducive to protecting the lifting piece 2.

[0175] Please refer to FIG. 8 and FIG. 9. FIG. 8 is a structural schematic diagram of the transmission assembly 4 shown in FIG. 4. FIG. 9 is an exploded schematic diagram of the transmission assembly 4 shown in FIG. 8.

[0176] In some embodiments, the transmission assembly 4 can include a long balance bar 41, a short balance bar 42 and two connecting rods 43.

[0177] For example, the long balance bar 41 can include two long bars 411 and two long support bars 412. The two long bars 411 are arranged opposite to each other along the second direction X. The two long support bars 412 are respectively connected between the two ends of the two long bars 411 along the first direction Y. The long balance bar 41 can be approximately frame-shaped. In the embodiments of the present application, the number of the long support bars 412 is taken as two for example. In other embodiments, the number of the long support bars 412 can also be one, three or more. Alternatively, the long balance bar 41 can not include the long support bars 412, which is not limited in the present application.

[0178] For example, the short balance bar 42 can include two short bars 421 and a short support bar 422. The two short bars 421 are arranged opposite to each other along the second direction X. The two ends of the short support bar 422 are respectively connected to the two short bars 421.

[0179] For example, one link 43 can correspond to one long rod 411 and one short rod 421, and the link 43 can be rotatably connected between the corresponding long rod 411 and short rod 421.

[0180] In the embodiment, the transmission assembly 4 can include two groups of transmission members 44, each group of transmission members 44 including one long rod 411, one link 43 and one short rod 421, and the two groups of transmission members 44 can be located on the two sides of the lifting mechanism 10 in the second direction X, respectively, and arranged oppositely and spaced apart. Among them, the two groups of transmission members 44 can be connected through the long support rod 412 and the short support rod 422, which improves the smoothness of the transmission of the transmission assembly 4.

[0181] In some embodiments, the long rod 411 can have a first end 4111, a second end 4112 and an adapter portion 4113, and the adapter portion 4113 of the long rod 411 can be located between the first end 4111 of the long rod 411 and the second end 4112 of the long rod 411. Among them, the first end 4111 of the long rod 411 can be provided with a first connecting hole 4111a, the second end 4112 of the long rod 411 can be provided with a second connecting hole 4112a, and the adapter portion 4113 of the long rod 411 can be provided with a third connecting hole 4113a.

[0182] For example, the adapter portion 4113 of the long rod 411 can also be provided with a through shaft hole 4113b, and the through shaft hole 4113b has an opening towards the bottom side of the long rod 411, so that other components can be clamped or passed through the long rod 411 to be installed on the components in the transmission assembly 4.

[0183] In some embodiments, the long rod 411 can include a first rod 411a, a second rod 411b and a third rod 411c connected in sequence. The first end 4111 of the long rod 411 and the adapter portion 4113 of the long rod 411 can be located at the first rod 411a, and the second end 4112 of the long rod 411 can be located at the third rod 411c. Among them, part of the second rod 411b can be bent to connect the first rod 411a and the third rod 411c. Of course, in other embodiments, the first rod 411a, the second rod 411b and the third rod 411c can also be connected in a straight line.

[0184] For example, the bottom side of the long rod 411 is a plane. In the third direction Z, the height of the first rod 411a can be greater than the height of the second rod 411b, and the height of the second rod 411b is greater than the height of the third rod 411c. In other embodiments, the adapter portion 4113 can also be located at the second rod 411b or the connection between the first rod 411a and the second rod 411b.

[0185] The first connecting hole 4111a and the third connecting hole 4113a are farther away from the bottom side of the long rod 411 than the second connecting hole 4112a. At this time, in the third direction Z, the first connecting hole 4111a and the third connecting hole 4113a are higher than the second connecting hole 4112a.

[0186] The third rod 411c gradually decreases in height in the third direction Z from the first end 4111 of the long rod 411 to the second end 4112 of the long rod 411, so that the top side of the third rod 411c is inclined, thereby reducing the size of the second end 4112 of the long rod 411 in the third direction Z.

[0187] The two long support rods 412 can be respectively fixed between the first rods 411a and the third rods 411c of the two long rods 411, which is conducive to improving the overall structural strength of the long balance rod 41. For example, one long support rod 412 can be connected between the first rods 411a of the two long rods 411 and arranged at the end close to the first end 4111 of the long rod 411. For example, the long support rod 412 can be wavy. In the third direction Z, the height of the long support rod 412 can be smaller than the size of the first rod 411a, and the long support rod 412 can be fixed to the part of the first rod 411a close to the bottom side, so that there is a receiving space between the two first rods 411a, which can be used to install other components, thereby improving the space utilization.

[0188] For example, the other long support rod 412 can be connected between the third rods 411c of the two long rods 411. The long support rod 412 can be connected to the end of the second end 4112 of the two long rods 411. For example, the long support rod 412 can have an avoidance area 412a formed by the part of the surface of the long support rod 412 away from the first end 4111 of the long rod 411 recessed towards the first end 4111 of the long rod 411.

[0189] In the embodiments of the present application, the shapes of the two long rods 411 can be different. For example, the bending degree of the second rod 411b of one long rod 411 can be greater than that of the second rod 411b of the other long rod 411, and the distance between the first rods 411a of the two long rods 411 is smaller than the distance between the third rods 411c of the two long rods 411. In other embodiments, the two long rods 411 can also have a symmetrical structure.

[0190] Please refer to FIG. 9 and FIG. 10, FIG. 10 is a structural schematic diagram of the short balance rod 42 shown in FIG. 9 from another perspective.

[0191] In some embodiments, the short rod 421 can include a first rotating portion 4211, a second rotating portion 4212 and a third rotating portion 4213. The second rotating portion 4212 can be connected to the first rotating portion 4211, and the third rotating portion 4213 can be connected to the second rotating portion 4212. The first rotating portion 4211, the second rotating portion 4212 and the third rotating portion 4213 can be arranged approximately along the first direction Y. The first rotating portion 4211 can have a dimension along the third direction Z that is greater than a dimension of the second rotating portion 4212 along the third direction Z. For example, a projection of the short rod 421 along the second direction X can be approximately L-shaped. The first rotating portion 4211 can have a first rotating hole 4211a, the second rotating portion 4212 can have a second rotating hole 4212a, and the third rotating portion 4213 can have a third rotating hole 4213a.

[0192] For example, the first rotating portion 4211 can further have a recessed space 4211b located on a side of the first rotating portion 4211 facing the other short rod 421. The recessed space 4211b can extend from a top side of the first rotating portion 4211 to a bottom side of the first rotating portion 4211 and can be in communication with the first rotating hole 4211a. The first rotating portion 4211 can further have a first abutting surface 4211c. In a circumferential direction of the first rotating hole 4211a, the first abutting surface 4211c can face in a first direction.

[0193] In embodiments of the present application, the two short rods 421 can have different shapes and sizes to facilitate assembly with other structural components. In other embodiments, the two short rods 421 can be symmetrical.

[0194] In some embodiments, the short support rod 422 can include a rod body 4221, a connecting portion 4222 and an abutting portion 4223. The rod body 4221 can be connected between the first rotating portions 4211 of the two short rods 421. The connecting portion 4222 can be connected to the rod body 4221. The abutting portion 4223 can be connected to an end of the connecting portion 4222 that is away from the rod body 4221 and can be arranged at an angle with respect to the connecting portion 4222. For example, the abutting portion 4223 can be perpendicular to the connecting portion 4222 or approximately perpendicular to the connecting portion 4222, and the abutting portion 4223 and the connecting portion 4222 can be approximately L-shaped.

[0195] The abutting portion 4223 can have a second abutting surface 4223a. In a circumferential direction of the first rotating hole 4211a, the second abutting surface 4223a can face in a second direction, which is opposite to the first direction. That is, in the circumferential direction of the first rotating hole 4211a, the first abutting surface 4211c and the second abutting surface 4223a can face in opposite directions.

[0196] Exemplarily, the short supporting rod 422 is connected to the first rotating part 4211, and the connection position is staggered with the first rotating hole 4211a, so that when the short supporting rod 422 is forced, the whole short balance rod 42 can be driven to move around the axis of the first rotating hole 4211a. The short supporting rod 422 can be connected to the bottom side of the first rotating part 4211, so that the space between the two short rods 421 can be used to install other components, thereby improving the space utilization. In addition, the first rotating hole 4211a can be arranged on the top side of the first rotating part 4211, and the distance between the short supporting rod 422 and the first rotating hole 4211a is large, which is beneficial to increase the force arm generated when the short supporting rod 422 is forced, and is beneficial to drive the short balance rod 42 to move.

[0197] In some embodiments, referring to FIGS. 8 and 9, the connecting rod 43 can have a first connecting end 431 and a second connecting end 432. The first connecting end 431 of the connecting rod 43 can be provided with a connecting column 431a, and the second connecting end 432 of the connecting rod 43 can be provided with a connecting hole 432a.

[0199] Exemplarily, the first connecting shaft 441 can have a limiting flange 441a and a limiting groove 441b, and the limiting flange 441a and the limiting groove 441b can be located at two ends of the first connecting shaft 441 respectively. The outer diameter of the limiting flange 441a is greater than the outer diameter of the main body portion of the first connecting shaft 441, and the outer diameter of the limiting groove 441b is less than the outer diameter of the main body portion of the first connecting shaft 441.

[0203] Exemplarily, each of the transmission groups 44 can further include a snap ring 445, one side of the snap ring 445 can have an opening, so that other components can be clamped into the snap ring 445 through the opening. Among them, the snap ring 445 can be "half-round". Among them, the half-round is not strictly limited to half a circle, but is a non-complete circle, which is usually larger than half a circle.

[0204] Exemplarily, the transmission assembly 4 can further include a first rotating shaft 446. The first rotating shaft 446 can have a limiting flange 446a, the outer diameter of the limiting flange 446a is larger than the outer diameter of the main body part of the first rotating shaft 446. Among them, the number of the first rotating shaft 446 is one. The length of the first rotating shaft 446 is greater than the length of the first connecting shaft 441, the second connecting shaft 442, the third connecting shaft 443 and the fourth connecting shaft 444.

In this embodiment, the short balance rod 42 can drive the short rod 421 to move together after being stressed, and drive the long rod 411 to move together through the connecting rod 43, so that the long rod 411 and the short rod 421 move synchronously.

[0208] In some examples, the rotating column 431a of the first rotating end 431 of the connecting rod 43 can be inserted into the third connecting hole 4113a of the rotating part 4113 of the long rod 411, so that the first rotating end 431 of the connecting rod 43 is rotationally connected to the long rod 411. The rotating hole 432a of the connecting rod 43 is coaxially arranged with the second rotating hole 4212a of the second rotating part 4212 of the short rod 421, and the third connecting shaft 443 passes through the shaft hole 4113b and enters the rotating hole 432a of the second rotating end 432 of the connecting rod 43 and the second rotating hole 4212a of the short rod 421, so that the second rotating end 432 of the connecting rod 43 is rotationally connected to the short rod 421.

[0212] For example, the first end 2a of the lifting member 2 can be located between the second ends 4112 of the two long rods 411, and the second end 2b of the lifting member 2 can be located between the two short rods 421.

[0213] The second end 4112 of each long rod 411 is rotatably connected to the first end 2a of the lifting member 2. For example, a fitting hole 24a of the lifting member 2 is provided with the second end 4112 of one long rod 411 of the set of transmission members 44 and a second connecting shaft 442. The second connecting shaft 442 passes through the second connecting hole 4112a of the second end 4112 of the long rod 411 and extends into the fitting hole 24a of the lifting member 2, so that the second end 4112 of the long rod 411 is rotatably connected to the first end 2a of the lifting member 2.

[0214] The third rotating part 4213 of each short rod 421 is slidably connected to the second end 2b of the lifting member 2. For example, a sliding groove 25a of the lifting member 2 is provided with the third rotating part 4213 of one short rod 421 of the set of transmission members 44 and a fourth connecting shaft 444. The fourth connecting shaft 444 passes through the third rotating hole 4213a of the third rotating part 4213 of the short rod 421 and is at least partially located in the sliding groove 25a, so that the fourth connecting shaft 444 and the third rotating part 4213 of the short rod 421 are slidably connected to the second end 2b of the lifting member 2.

[0215] Please refer to FIG. 14A and FIG. 14B. FIG. 14A is a schematic diagram of part of the lifting mechanism 10 shown in FIG. 3A, and FIG. 14B is a schematic diagram of part of the lifting mechanism 10 shown in FIG. 14A from another perspective.

[0216] In some embodiments, the lifting member 2 and the transmission assembly 4 are movably installed in the base 1. For example, part of the structure of the lifting member 2 and the transmission assembly 4 can be located in the accommodation space 11 of the base 1, another part of the structure of the lifting member 2 can be located in the accommodation hole 11a of the base 1, and the top side of the lifting member 2 can be exposed by the first accommodation opening 111a.

[0217] The base 1 is an integrated structure assembled by the first part 1e of the base 1 and the second part 1f of the base 1. By setting the opening area of the second accommodation opening 112a to be larger than the opening area of the first accommodation opening 111a, the installation process of the lifting member 2 and the transmission assembly 4 can be facilitated.

[0218] In addition, please refer to FIG. 3A and FIG. 3B. When the lifting mechanism 10 is installed in the electronic device 1000, the decorative ring 22 of the lifting member 2 and at least part of the second part 1f of the base 1 can be exposed relative to the through hole 3004 (as shown in FIG. 2A) of the camera decoration 3003. The decorative ring 22 and the second part 1f are made of metal or other materials, which can improve the structural strength and make them less likely to wear. In addition, the second part 1f made of metal or other materials can also better protect the lifting member 2.

[0219] Please refer to Fig. 15A, which is a sectional view of the part structure of the lifting mechanism 10 shown in Fig. 14A at D-D.

[0220] In some embodiments, the first end 4111 of each of the two long rods 411 can be rotatably connected to the first fixed part 13 of the base 1.

[0221] For example, the two long rods 411 can be located between the first side wall 1b and the protrusion near the first side wall 1b in the first fixed part 13, and between the third side wall 1d and the protrusion near the third side wall 1d in the first fixed part 13. One of the first connecting shafts 441 can pass through the first fixed hole 132 of the first side wall 1b, the first connecting hole 4111a of the first end 4111 of the long rod 411, and extend into the first fixed hole 132 of the protrusion near the first side wall 1b in the first fixed part 13. The other first connecting shaft 441 can pass through the first fixed hole 132 of the third side wall 1d, the first connecting hole 4111a of the first end 4111 of the other long rod 411, and extend into the first fixed hole 132 of the protrusion near the third side wall 1d in the first fixed part 13. At this time, the axis of the first connecting hole 4111a of the long rod 411 coincides with the axis of the first fixed hole 132 of the first fixed part 13, which is beneficial to improve the stability of the rotatable connection between the long rod 411 and the base 1. At this time, when the long rod 411 rotates relative to the base 1, it can also be considered that the long rod 411 can rotate about the central axis of the first connecting shaft 441 relative to the base 1.

[0222] For example, two clamping rings 445 can be provided corresponding to the two first connecting shafts 441. The clamping ring 445 can be located between the long rod 411 and the adjacent first fixed part 13, and the clamping ring 445 can be clamped in the limiting groove 441b of the first connecting shaft 441. The clamping ring 445 can be used to cooperate with the limiting groove 441b of the first connecting shaft 441 to fix the relative position of the long rod 411 and the base 1 in the axial direction of the first connecting shaft 441, so as to avoid the change of the relative position of the long rod 411 and the base 1 in the axial direction of the first connecting shaft 441 during the movement of the transmission assembly 4 relative to the base 1, thereby affecting the reliability of the transmission assembly 4.

[0223] Please refer to Fig. 15B, which is a sectional view of the part structure of the lifting mechanism 10 shown in Fig. 14A at E-E.

[0224] In some embodiments, the first rotating part 4211 of the short rod 421 is rotationally connected to the second fixing part 14 of the base 1. The first rotating shaft 446 can sequentially pass through the first rotating hole 4211a of the first rotating part 4211 of one of the short rods 421, the first rotating shaft hole 141 of the second fixing part 14, and the first rotating hole 4211a of the other short rod 421, so that the short rod 421 is rotationally connected to the base 1 through the first rotating shaft 446, which facilitates to improve the stability and reliability of the rotational connection between the short rod 421 and the base 1. At this time, when the first rotating part 4211 of the short rod 421 rotates relative to the base 1, it can also be regarded that the first rotating part 4211 of the short rod 421 rotates relative to the base 1 with the central axis of the first rotating shaft 446 as the rotation axis.

[0225] In this embodiment, the first end 4111 of the long rod 411 and the first rotating part 4211 of the short rod 421 are both rotationally connected to the base 1, and the second end 4112 (shown in FIGS. 13A and 13B) of the long rod 411 and the third rotating part 4213 (shown in FIGS. 13A and 13B) of the short rod 421 are also both connected to the lifting piece 2 (shown in FIGS. 13A and 13B), so that the long rod 411 and the short rod 421 can both drive the lifting piece 2 connected thereto to move relative to the base 1 when they move relative to the base 1.

[0226] Please refer to FIG. 12 again. The driving assembly 3 (not shown in FIG. 12) of the present application can drive the lifting piece 2 to move relative to the base 1 by driving a certain component (such as the short rod 421, the long rod 411, or the connecting rod 43) of the driving transmission member 44, and through the transmission connection among the short rod 421, the connecting rod 43, the long rod 411, and the lifting piece 2, so as to realize the conversion between the extended state and the retracted state of the lifting mechanism 10.

[0227] For example, in the embodiment of the present application, the first rotating part 4211 of the short rod 421 is rotationally connected to the second fixing part 14 of the base 1 (shown in FIG. 15B), and when the first rotating part 4211 of the short rod 421 is subjected to the driving force of the driving assembly 3, the first rotating part 4211 of the short rod 421 will rotate relative to the base 1 with the central axis of the first rotating shaft 446 as the rotation axis. The third rotating part 4213 (shown in FIGS. 13A and 13B) of the short rod 421 is slidingly connected to the second end 2b (shown in FIGS. 13A and 13B) of the lifting piece 2, and the short rod 421 can also drive the second end 2b of the lifting piece 2 to move relative to the base 1, so that the second end 2b of the lifting piece 2 is displaced in the third direction Z.

[0228] Meanwhile, the connecting rod 43 (as shown in FIG. 13A) is rotatably connected between the short rod 421 and the long rod 411. When the first rotating part 4211 of the short rod 421 is subjected to a force, the connecting rod 43 can transmit the force received by the short rod 421 to the long rod 411, so that the long rod 411 moves under the force, and the first end 4111 of the long rod 411 is rotatably connected to the first fixed part 13 of the base 1 (as shown in FIG. 15A). When the long rod 411 is subjected to a force, the long rod 411 rotates relative to the base 1 with the first fixed part 13 as the movement fulcrum. The second end 4112 of the long rod 411 is rotatably connected to the first end 2a of the lifting piece 2, and the long rod 411 can also drive the first end 2a of the lifting piece 2 to rotate relative to the base 1, so that the first end 2a of the lifting piece 2 moves in the third direction Z, thereby realizing the lifting process of the lifting piece 2 relative to the base 1.

[0229] Please refer to FIG. 12, FIG. 16A and FIG. 16B again. FIG. 16A is a side view schematic diagram of the lifting mechanism 10 shown in FIG. 14A, and FIG. 16B is a mechanism diagram of the lifting mechanism 10 shown in FIG. 16A. In FIG. 16A, the dotted line represents the base 1. In FIG. 16B, the dotted line with arrows represents the rotating direction.

[0230] Hereinafter, for the convenience of description, the hollow circle in the mechanism diagram represents the rotatable part in the lifting mechanism 10, the straight line represents the part that can rotate around the hollow circle in the lifting mechanism 10, the two straight lines between the solid sector represent the fixed connection, the triangle with oblique line at the bottom represents the fixed point, and there is no movement interference between the intersecting straight lines.

[0231] In some embodiments, in the YZ plane, the part between the first fixed part 13 (as shown in FIG. 15A) and the second fixed part 14 (as shown in FIG. 15B) of the base 1 can be regarded as a fixed rod 16 formed by a part of the base 1. The long rod 411 can include a first segment 4114 and a second segment 4115 fixedly connected, the first segment 4114 of the long rod 411 is the center line of the first connecting hole 4111a and the third connecting hole 4113a, and the second segment 4115 of the long rod 411 is the center line of the third connecting hole 4113a and the second connecting hole 4112a of the long rod 411. The short rod 421 can include a first segment 4214 and a second segment 4215 fixedly connected, the first segment 4214 of the short rod 421 is the center line of the first rotating hole 4211a (as shown in FIG. 13A) of the first rotating part 4211 and the second rotating hole 4212a (as shown in FIG. 10) of the second rotating part 4212, and the second segment 4115 of the short rod 421 is the center line of the second rotating hole 4212a and the third rotating hole 4213a (as shown in FIG. 13A) of the third rotating part 4213.

[0232] It can be understood that, in the embodiment of the present application, the driving of the lifting piece 2 relative to the base 1 by the driving assembly 3 is also understood as the first section 4114 of the short rod 421 being rotatably connected to one end of the fixed rod 16 (the second fixed portion 14), and when the first section 4114 of the short rod 421 is subjected to a force, the first section 4114 of the short rod 421 will rotate with the one end of the fixed rod 16 (the center axis of the first pivot hole 141 of the second fixed portion 14, that is, the center axis of the first pivot 446) as the center of motion. The second section 4115 of the short rod 421, which is away from the one end of the first section 4114 of the short rod 421, is also slidably connected to the second end 2b of the lifting piece 2, and the short rod 421 can drive the second end 2b of the lifting piece 2 to move relative to the base 1, so that the second end 2b of the lifting piece 2 is displaced in the third direction Z.

[0233] Meanwhile, due to the rotatable connection between the first section 4114 of the short rod 421, the connecting rod 43, and the first section 4114 of the long rod 411 connected in sequence, when the first section 4114 of the short rod 421 is subjected to a force, the force and motion of the short rod 421 are transmitted to the first section 4114 of the long rod 411 via the connecting rod 43, so that the short rod 421 and the long rod 411 move together, and the first section 4114 of the long rod 411 is also rotatably connected to the other end of the fixed rod 16 (the first fixed portion 13). Therefore, when the long rod 411 is subjected to a force, the long rod 411 will rotate relative to the base 1 with the other end of the fixed rod 16 as the fulcrum. The second section 4115 of the long rod 411, which is away from the one end of the first section 4114 of the long rod 411, is rotatably connected to the first end 2a of the lifting piece 2, and the long rod 411 can move under the driving of the short rod 421, thereby driving the first end 2a of the lifting piece 2 to move relative to the base 1, so that the first end 2a of the lifting piece 2 is displaced in the third direction Z.

[0234] In the embodiment, the fixed rod 16, the first section 4114 of the long rod 411, the connecting rod 43, and the first section 4114 of the short rod 421 are rotatably connected in sequence, which can constitute a four-bar linkage mechanism. When the short rod 421 is subjected to a force, the second section 4115 of the long rod 411 and the second section 4115 of the short rod 421 can also be lifted together with the movement of the four-bar linkage mechanism, thereby driving the lifting piece 2 to be lifted together.

[0235] Specifically, in the embodiment, the four-bar linkage mechanism is provided, and the short rod 421, the long rod 411 and the connecting rod 43 in the four-bar linkage mechanism are in transmission connection with each other. When the short rod 421 is subjected to a force, the force and movement of the short rod 421 are transmitted to the long rod 411 through the connecting rod 43, so that the short rod 421 and the long rod 411 move together, and the driving assembly 3 can drive the four-bar linkage mechanism to move, so as to realize the lifting of the first end 2a and the second end 2b of the lifting piece 2 together, realize the conversion between the extended state and the retracted state of the lifting mechanism 10, and improve the extension and retraction smoothness of the lifting mechanism 10. In addition, compared with the driving scheme in which the driving assembly needs to drive the two ends of the lifting piece to move respectively so as to drive the lifting piece to lift relative to the base when the four-bar linkage mechanism is not formed in the lifting mechanism, the lifting mechanism 10 provided in the application is more labor-saving, convenient, simple in structure and high in reliability. In other words, in the embodiment of the application, the transmission member 44 and the base 1 together form a four-bar linkage mechanism. The driving assembly 3 of the application can drive a certain component (for example, the short rod 421, the long rod 411 or the connecting rod 43) in the transmission member 44 to move, so as to drive the four-bar linkage mechanism to move, and realize the conversion between the extended state and the retracted state of the lifting mechanism 10.

[0236] For example, in the embodiment of the application, as shown in FIGS. 14A and 16A, the lifting mechanism 10 is in the retracted state. In the retracted state, the top side of the lifting piece 2 can be exposed relative to the first receiving opening 111a of the base 1 (see FIG. 14A). In some examples, the top surface of the first decorative part 22a of the lifting piece 2 and the top surface of the light-transmitting part 23 can be flush with the top surface of the second part 1f of the base 1.

[0237] In some examples, as shown in FIG. 16B, in the retracted state, when the first section 4114 of the short rod 421 is subjected to a driving force F1 in the clockwise direction from the perspective of the second direction X, the first section 4114 of the short rod 421 can rotate in the clockwise direction, and the second section 4115 of the short rod 421 is driven to rotate in the clockwise direction, so as to drive the second end 2b of the lifting piece 2 to displace in the positive direction +Z of the third direction. At the same time, the short rod 421 drives the first section 4114 of the long rod 411 to rotate in the clockwise direction through the connecting rod 43, so that the first section 4114 of the long rod 411 drives the second section 4115 of the long rod 411 to rotate in the clockwise direction, thereby driving the first end 2a of the lifting piece 2 to displace in the positive direction +Z of the third direction, so as to realize the overall lifting of the lifting piece 2.

[0238] Please refer to FIG. 17A to FIG. 18B, FIG. 17A is a structural schematic diagram of the partial structure of the lifting mechanism 10 in another state, FIG. 17B is a schematic diagram of the partial structure of the lifting mechanism 10 shown in FIG. 17A, FIG. 18A is a side view schematic diagram of the lifting mechanism 10 shown in FIG. 17A, and FIG. 18B is a mechanism diagram of the lifting mechanism 10 shown in FIG. 18A. In FIG. 18A, the point indicated by the dotted line represents the base 1, and the arrowed dotted line in FIG. 18B represents the rotating direction.

[0239] In the embodiment, as shown in FIG. 16A and FIG. 16B, when the short rod 421 is subjected to the driving force F1, the lifting member 2 is lifted relative to the base 1, and the lifting mechanism 10 is switched to the extended state. As shown in FIG. 17A, the lifting mechanism 10 is in the extended state, and at this time, in the extended state, the top side of the lifting member 2 can protrude relative to the first receiving opening 111a of the base 1. In some examples, the first decorative part 22a and the light-transmitting part 23 of the lifting member 2 can protrude relative to the second part 1f of the base 1, and the second decorative part 22b can be exposed relative to the base 1.

[0240] In some examples, as shown in FIG. 17B to FIG. 18B, in the extended state, when the first segment 4114 of the short rod 421 is subjected to the retracting force F2 in the counterclockwise direction from the perspective of the second direction X, the first segment 4114 of the short rod 421 can rotate in the counterclockwise direction and drive the second segment 4115 of the short rod 421 to rotate in the counterclockwise direction, thereby driving the second end 2b of the lifting member 2 to displace in the negative direction -Z of the third direction. At the same time, the short rod 421 also drives the first segment 4114 of the long rod 411 to rotate in the counterclockwise direction through the connecting rod 43, so that the first segment 4114 of the long rod 411 drives the second segment 4115 of the long rod 411 to rotate in the counterclockwise direction, thereby driving the first end 2a of the lifting member 2 to displace in the negative direction -Z of the third direction, so as to realize the overall descent of the lifting member 2, and make the lifting member 2 descend to the state shown in FIG. 14A and FIG. 16A.

[0241] In this embodiment, the first segment 4114 of the short rod 421 and the second segment 4115 of the short rod 421 are arranged at an angle, which is conducive to matching the movement demand and space demand of the four-bar linkage mechanism.

[0242] Please refer to FIG. 12 to FIG. 13B again. Exemplarily, the opening of the first avoiding slot 26 of the lifting member 2 can face the long rod 411, and the first avoiding slot 26 can accommodate a part of the long rod 411 in the retracted state. In this embodiment, in the retracted state, since the lifting member 2 can avoid the long rod 411 through the first avoiding slot 26, the arrangement of the lifting member 2 and the transmission assembly 4 is more compact, which can reduce the size of the lifting mechanism 10 in the third direction Z, and is conducive to realizing the lightweight design of the electronic device 1000.

[0243] Exemplarily, the space formed between the two third rotating portions 4213 of the short rod 421 can accommodate at least part of the structure of the second end 2b of the lifting member 2, so that the rotating connection of the short rod 421 and the second end 2b of the lifting member 2 is more stable.

[0244] In some embodiments, the two groups of transmission members 44 can be connected to the first side 2c of the lifting member 2 and the second side 2d of the lifting member 2 respectively, and the two groups of transmission members 44 located on both sides of the lifting member 2 can form two groups of four-bar mechanisms together with the base 1.

[0245] In the present embodiment, the two long rods 411 are fixedly connected through the long supporting rod 412, so that the two second connecting shafts 442 rotatingly connected to the first end 2a of the lifting member 2 are located on the same long supporting rod 412, thereby enabling the two second connecting shafts 442 to move synchronously, and the two long rods 411 synchronously drive the lifting member 2 to move, so as to realize the lifting balance of the lifting member 2 at the first side 2c and the second side 2d of the first end 2a, and improve the smoothness of the lifting of the lifting member 2.

[0246] The two short rods 421 are fixedly connected through the short supporting rod 422, so that the two fourth connecting shafts 444 slidingly connected to the second end 2b of the lifting member 2 are located on the short balancing rod 42, thereby enabling the two fourth connecting shafts 444 to move synchronously, and the two short rods 421 synchronously drive the lifting member 2 to move, so as to realize the lifting balance of the lifting member 2 at the first side 2c and the second side 2d of the second end 2b.

[0247] In the present embodiment, since the two groups of transmission members 44 are connected through the long supporting rod 412 and the short supporting rod 422, the two groups of four-bar mechanisms can move simultaneously, and under the common driving of the two short rods 421 and the two long rods 411, the first end 2a and the second end 2b of the lifting member 2 can simultaneously lift along the third direction Z, so that the overall lifting of the lifting member 2 is stable. Therefore, by simultaneously driving the two groups of four-bar mechanisms, the two sides of the lifting member 2 can be simultaneously lifted, and the stability of the lifting of the lifting member 2 is improved.

[0248] Please refer to FIG. 12, in some embodiments, the driving assembly 3 can act the driving force F1 on the short supporting rod 422 (please refer to F1 in FIG. 12), drive the short supporting rod 422 through the driving force F1, so as to drive the short rod 421 and the long rod 411, thereby enabling the short rod 421 and the long rod 411 to jointly drive the lifting member 2 to rise.

[0249] The short supporting rod 422 is connected between the two short rods 421, and the first rotating hole 4211a is arranged at the top side of the first rotating part 4211. The short supporting rod 422 can be connected to the bottom side of the first rotating part 4211, which is beneficial to increase the distance between the short supporting rod 422 and the first rotating hole 4211a of the first rotating part 4211 in the first direction Y, so as to increase the force arm of the driving force F1, thereby improving the driving efficiency.

[0250] Referring to FIG. 17B, in some embodiments, the driving assembly 3 can apply a retracting force F2 to the two short rods 421 (see F2 in FIG. 17B), and push the short rods 421 through the retracting force F2, so as to drive the short rods 421 and the long rod 411, thereby driving the short rods 421 and the long rod 411 to jointly drive the lifting member 2 to descend.

[0251] In other embodiments, the force of the driving assembly 3 for driving the lifting member 2 to extend and retract can act on the short rod 421, or the long rod 411, or the short supporting rod 422, etc. In the embodiments of the present application, only the driving force F1 of the driving assembly 3 acting on the short supporting rod 422 and the retracting force F2 of the driving assembly 3 acting on the short rod 421 are illustrated, and the object and specific position of the force of the driving assembly 3 are not strictly limited.

[0252] Referring to FIG. 19, FIG. 19 is a schematic view of the lifting mechanism 10 in the lifting process shown in FIG. 16A.

[0253] In some embodiments, the axis of the lifting member 2 in the initial position (see O in FIG. 16A) coincides with the axis of the lifting member 2 in the extended position (see O' in FIG. 18A). The axis of the lifting member 2 in the initial position is parallel to the Z direction.

[0254] In the present embodiment, the axis of the lifting member 2 coincides in the initial position and the extended position, so that the relative position of the lifting member 2 and the base 1 (see FIG. 18A) in the XY plane has no deviation in the initial position and the extended position, and the center position of the light-transmitting member 23 (see FIG. 17A) of the lifting member 2 can be kept without deviation, thereby ensuring the light collecting quality of the camera module 20 in the internal space of the lifting member 2, and ensuring the camera quality of the camera device 100.

[0255] The center of the second connecting hole 4112a of the long rod 411 (which can also be considered as the axis of the second connecting shaft 442) is parallel to the third direction Z on the line connecting the extended position and the retracted position. In other words, the fitting hole 24a of the lifting piece 2 (which can also be considered as the first end 2a of the lifting piece 2) is parallel to the third direction Z on the line connecting the extended position and the retracted position. In the process of converting the lifting piece 2 from the initial position to the extended position, the long rod 411 rotates around the axis of the first connecting shaft 441, so that the movement path of the second end 4112 of the long rod 411 and the second connecting shaft 442 is a circular arc. In other words, the movement path of the first end 2a of the lifting piece 2 in the process of rising and falling is a circular arc, and the circular arc has the axis of the first connecting shaft 441 as the center. Therefore, the first end 2a of the lifting piece 2 has a movement distance in the first direction Y in the process of rising and falling, so that the second end 2b of the lifting piece 2 has a movement distance in the first direction Y.

[0256] In the process of converting the lifting piece 2 from the initial position to the extended position, the short rod 421 (as shown in FIG. 17B) rotates around the axis of the first rotating shaft 446 (as shown in FIG. 17B), so that the movement path of the third rotating part 4213 of the short rod 421 and the fourth connecting shaft 444 is a circular arc. In other words, the movement path of the second end 2b of the lifting piece 2 in the process of rising and falling is a circular arc, and the circular arc has the axis of the first rotating shaft 446 as the center. Therefore, the second end 2b of the lifting piece 2 has a movement distance in the first direction Y in the process of rising and falling.

[0257] In the process of converting the lifting piece 2 from the initial position to the extended position, the short rod 421 (as shown in FIG. 17B) rotates around the axis of the first rotating shaft 446 (as shown in FIG. 17B), so that the movement path of the third rotating part 4213 of the short rod 421 and the fourth connecting shaft 444 is a circular arc. In other words, the movement path of the second end 2b of the lifting piece 2 in the process of rising and falling is a circular arc, and the circular arc has the axis of the first rotating shaft 446 as the center. Therefore, the second end 2b of the lifting piece 2 has a movement distance in the first direction Y in the process of rising and falling.

[0258] The sliding groove 25a can be a straight groove, and the extension direction of the sliding groove 25a can be perpendicular to the axis of the lifting member 2, which is beneficial to the lifting height consistency of the first end 2a and the second end 2b of the lifting member 2, and improves the stability of the lifting member 2. In other embodiments, the extension direction of the sliding groove 25a can also form an angle with the axis of the lifting member 2. In other embodiments, the sliding groove 25a can also be an arc-shaped groove or a spline curve groove, which is specifically designed according to the movement path of the fourth connecting shaft 444 during the lifting process of the lifting member 2, as long as the lifting height consistency of the first end 2a and the second end 2b of the lifting member 2 can be achieved.

[0259] In the embodiment, the lifting member 2 can have a first avoiding groove 26 (as shown in FIG. 13A), which is used to avoid other structural members, such as the internal structure of the base 1, during the lifting process of the lifting member 2, to avoid impact, damage or movement deviation in the first direction Y that affects the lifting precision, so as to avoid collision of the lifting member 2 during the lifting process.

[0260] In some embodiments, referring to FIG. 19, in the retracted state, the first connecting hole 4111a of the long rod 411 is closer to the top side of the lifting mechanism 10 than the second connecting hole 4112a, and in the extended state, the position of the first connecting hole 4111a is unchanged, and the second connecting hole 4112a is closer to the top side of the lifting mechanism 10 than the first connecting hole 4111a. Since the center of the first connecting hole 4111a (i.e. the center axis of the first connecting shaft 441) is the rotation axis of the long rod 411, and the height of the first rod 411a of the long rod 411 is greater than the height of the third rod 411c in the third direction Z, by setting the first connecting hole 4111a to be higher than the second connecting hole 4112a in the retracted state, the movement of the third rod 411c in the third direction Z (i.e. the movement of the second connecting hole 4112a towards the top side of the lifting mechanism 10) during the driving of the lifting member 2 to move upwards in the third direction Z can utilize the size of the first rod 411a in the third direction Z, so that the size space occupied by the lifting mechanism 10 in the third direction Z can be reduced without changing the movement stroke of the lifting member 2, which is beneficial to the slim design of the lifting mechanism 10.

[0261] In the embodiment, the top side of the third rod 411c of the long rod 411 is inclined, which reduces the size of the second end 4112 of the long rod 411 in the third direction Z, so that the weight of the long rod 411 is light, thereby reducing the power consumption required for driving the movement of the long rod 411, and improving the movement flexibility of the long rod 411.

[0262] In some other embodiments, the fitting hole 24a of the first end 2a of the lifting member 2 can be changed into a slot structure, and the sliding slot 25a of the second end 2b of the lifting member 2 can be changed into a hole structure. The second end 4112 of the long rod 411 is slidingly connected to the second end 2b of the lifting member 2, and the second rotating part 4212 of the short rod 421 is rotatably connected to the first end 2a of the lifting member 2. In this embodiment, the motion deviation of the first end 2a and the second end 2b of the lifting member 2 in the first direction Y during the lifting process is eliminated through the slot structure of the first end 2a of the lifting member 2, and the smoothness of the lifting motion of the lifting member 2 is improved.

[0263] In some other embodiments, the transmission assembly 4 can be designed by adjusting the length and connection position of the four-bar linkage, so that the motion paths of the second end 4112 of the long rod 411 and the second connecting shaft 442, and the motion paths of the third rotating part 4213 of the short rod 421 and the fourth connecting shaft 444 are synchronized in the motion in the first direction Y. At this time, the second end 4112 of the long rod 411 can be rotatably connected to the first end 2a of the lifting member 2, and the third rotating part 4213 of the short rod 421 can be rotatably connected to the second end 2b of the lifting member 2. The specific setting structure of the four-bar linkage is not strictly limited in the embodiments of the present application.

[0264] Please refer to FIG. 4, FIG. 20A to FIG. 21, FIG. 20A is a cross-sectional structure schematic view of the part structure of the lifting mechanism 10 shown in FIG. 14A at F-F, FIG. 20B is a cross-sectional structure schematic view of the part structure of the lifting mechanism 10 shown in FIG. 14A at G-G, and FIG. 21 is a cross-sectional structure schematic view of the part structure of the lifting mechanism 10 shown in FIG. 17A at H-H.

[0265] In some embodiments, the detection assembly 5 can include a position sensor 51 and a magnetic member 52. The position sensor 51 can be installed on the base 1, and the magnetic member 52 can be installed on the lifting member 2. The position sensor 51 can be located in the magnetic field generated by the magnetic member 52, and can detect the magnetic flux of the surrounding magnetic field to monitor the position of the lifting member 2 when the lifting member 2 moves relative to the base 1, thereby achieving position detection of the movement process of the lifting member 2 relative to the base 1. The position sensor 51 can be one or more of a Hall sensor, a Tunneling Magneto Resistance (TMR) sensor, and a Giant Magneto Resistance (GMR) sensor. In other embodiments, the magnetic member 52 can be fixed to the base 1, and the position sensor 51 can be fixed to the lifting member 2, which is not limited in the present application.

[0266] For example, the position sensor 51 can be mounted in the mounting groove 12c of the base 1, and the magnetic member 52 can be mounted in the mounting block 28 of the lifting member 2. For example, the position sensor 51 can have a sensing chip 511 and a packaging plate 512, the sensing chip 511 can be arranged on the packaging plate 512 and protrude relative to the packaging plate 512, the packaging plate 512 can be mounted in the mounting groove 12c of the base 1, and the sensing chip 511 can extend into the space between the base 1 and the lifting member 2 through the through hole 13c in the mounting groove 12c, which is conducive to improving the accuracy of the sensing chip 511 in detecting the magnetic flux of the magnetic field between the base 1 and the lifting member 2.

[0267] The magnetic member 52 can be used to generate a magnetic field, and when the lifting member 2 switches between the retracted state and the extended state, the magnetic member 52 moves with the movement of the lifting member 2, so that the relative position of the magnetic member 52 and the sensing chip 511 changes, thereby the value of the magnetic flux detected by the sensing chip 511 also changes accordingly, thereby realizing the monitoring of the movement process of the lifting member 2 by the detection assembly 5.

[0268] For example, referring to FIG. 14B and FIG. 20A, in some embodiments, the avoiding area 412a of the long support rod 412 of the transmission assembly 4 can correspond to the avoiding space 11c of the second side wall 1c of the base 1, and the two are communicated, and the mounting block 28 of the lifting member 2 can extend between the avoiding area 412a and the avoiding space 11c. At this time, at least part of the long support rod 412 can be located in the second avoiding groove 27 of the lifting member 2, and the lifting member 2, the transmission assembly 4 and the base 1 are arranged compactly, which is conducive to fully utilizing the internal space of the lifting mechanism 10 and realizing the miniaturization of the lifting mechanism 10. In addition, it is also conducive to shortening the distance between the mounting block 28 and the base 1, so as to make the position sensor 51 and the magnetic member 52 close to each other, thereby improving the detection accuracy.

[0269] Referring to FIG. 22, FIG. 22 is a sectional view of the part of the lifting mechanism 10 shown in FIG. 14A at I-I.

[0270] In some embodiments, in the retracted state, the lifting member 2 abuts against the second limiting surface 121 of the base 1. For example, in the retracted state, the bottom wall surface 261 of the first avoiding groove 26 of the lifting member 2 can abut against the second limiting surface 121.

[0271] In the embodiment of the present application, when the lifting member 2 is converted from the retracted state to the extended state, the second limiting surface 121 can limit the lifting member 2, preventing the lifting member 2 from continuing to descend, so as to avoid the lifting member 2 from colliding with other components inside the electronic device 1000 due to excessive retraction. In addition, since the lifting member 2 is in the retracted state when the camera device 100 is not shooting, the second limiting surface 121 can support the lifting member 2, so as to maintain the structural stability of the lifting mechanism 10 as a whole. The second limiting surface 121 is a surface formed by the existing structure of the base 1, and compared with adding other structures in the base 1 to achieve the limiting function, the lifting mechanism 10 of the embodiment of the present application has low cost and high space utilization.

[0272] For example, part of the structure of the base 1 can be located in the first avoiding slot 26, which is beneficial to improve the compactness of the arrangement of the lifting member 2 and the base 1, fully utilize the internal space of the lifting mechanism 10, and realize the miniaturization of the lifting mechanism 10.

[0273] Please refer to FIG. 23, which is a schematic diagram of the cross-sectional structure of the part of the structure of the lifting mechanism 10 shown in FIG. 14A at J-J.

[0274] In some embodiments, in the extended state, the second end 4112 of the long rod 411 abuts against the first limiting surface 131a. For example, the second ends 4112 of the two long rods 411 respectively abut against the two first limiting surfaces 131a.

[0275] In the embodiment of the present application, when the lifting member 2 is converted from the retracted state to the extended state, the first limiting surface 131a can limit the long rod 411, preventing the lifting member 2 from continuing to ascend, so as to avoid the lifting member 2 from excessive extension, ensure the consistent extension size of the lifting member 2 each time, and thus improve the stability of the electronic device 1000 during shooting. The first limiting surface 131a is a surface formed by the existing structure in the lifting mechanism 10, and compared with adding other structures to achieve the limiting function, the lifting mechanism 10 of the embodiment of the present application has low cost and high space utilization.

[0276] Please refer to FIG. 24A and FIG. 24B, FIG. 24A is a schematic diagram of the structure of the driving assembly 3 shown in FIG. 4. FIG. 24B is a schematic diagram of the structure of the driving assembly 3 shown in FIG. 4.

[0277] In some embodiments, the driving assembly 3 can include two driving groups 31, and each driving group 31 can include a motor 311, a worm 312, and a turbine 313. For example, each driving group 31 can further include a motor mounting plate 314, and the motor 311 can be fixed to the motor mounting plate 314. The motor 311 has an output shaft 3111, and the output shaft 3111 of the motor 311 is used to transmit the power generated by the motor 311 to an external device (such as the transmission assembly 4, the lifting member 2, etc.) connected to the output shaft 3111, so as to drive the external device to move.

[0278] Please refer to FIG. 24B and FIG. 25, and FIG. 25 is a structural schematic view of the two turbines 313 shown in FIG. 24B from another perspective.

[0279] In some embodiments, the turbine 313 can have a first shaft hole 3131, and the first shaft hole 3131 can pass through the turbine 313.

[0280] For example, the turbine 313 can include a transmission part 3132 and an engagement part 3133, and the transmission part 3132 and the engagement part 3133 can be arranged in the axial direction of the first shaft hole 3131, and the transmission part 3132 is connected to one side of the engagement part 3133. The turbine 313 can further have a groove 3134, and the groove 3134 can be located on the transmission part 3132 and can be partially arranged around the first shaft hole 3131. The turbine 313 can have a gear position surface 3134a, and the gear position surface 3134a can be formed on the groove wall of the groove 3134.

[0281] For example, the engagement part 3133 can have an incomplete tooth part 3133a, and the incomplete tooth part 3133a can be arranged on the outer periphery of the engagement part 3133 and can be partially arranged around the first shaft hole 3131. For example, the engagement part 3133 can further have a receiving groove 3133b, and the receiving groove 3133b can be arranged opposite to the incomplete tooth part 3133a, and the receiving groove 3133b can be recessed from the outer surface of the engagement part 3133 and can face the incomplete tooth part 3133a, and the receiving groove 3133b can be communicated with the first shaft hole 3131.

[0282] For example, the turbine 313 can further include an abutting protrusion 3135, and the abutting protrusion 3135 can be connected to the side of the engagement part 3133 away from the transmission part 3132 and can protrude relative to the engagement part 3133. The abutting protrusion 3135 can have a contact surface 3135a, and the contact surface 3135a can face opposite to the gear position surface 3134a.

[0283] In some embodiments, the structures of the incomplete tooth parts 3133a of the two turbines 313 of the driving assembly 3 are the same structure and have the same rotation direction. In other embodiments, the shapes of the two turbines 313 can also be the same shape, which is not limited in the present application.

[0284] Please refer to FIG. 24B again, in some embodiments, the worm 312 can have a mounting hole 3121, the mounting hole 3121 can pass through the worm 312 along the length direction of the worm 312. Wherein, the outer surface of the worm 312 can also have a helical tooth spirally arranged.

[0285] Wherein, the shapes of the two worms 312 of the driving assembly 3 can be the same; in other embodiments, the shapes of the two worms 312 can also be different, which is not limited in the present application.

[0286] Please refer to FIG. 24A, FIG. 24B, FIG. 26A and FIG. 26B, FIG. 26A is a partial structure diagram of the driving assembly 3 shown in FIG. 24B, and FIG. 26B is an exploded diagram of the partial structure of the driving assembly 3 shown in FIG. 26A.

[0287] In some embodiments, each driving group 31 can also include an elastic member 315. The elastic member 315 can have a first end 3151 and a second end 3152, the first end 3151 of the elastic member 315 and the second end 3152 of the elastic member 315 can be arranged along the central axis of the elastic member 315. For example, the elastic member 315 can be a torsion spring.

[0288] In the embodiments of the present application, the two elastic members 315 of the driving assembly 3 can be symmetrical structures. In other embodiments, the two elastic members 315 can also be asymmetrical structures.

[0289] For example, the driving assembly 3 can also include a sleeve 32, the elastic member 315 can be sleeved on the sleeve 32, the sleeve 32 can be used to support the elastic member 315 to increase the stability of the structure of the elastic member 315. Wherein, the central axis of the sleeve 32 can coincide with the central axis of the elastic member 315. In the embodiments of the present application, the number of the sleeve 32 can be one, and the two elastic members 315 can be sleeved on the same sleeve 32, at this time, the second ends 3152 of the two elastic members 315 can be close to each other and oppositely arranged, and the first ends 3151 of the two elastic members 315 are away from each other. In other embodiments, the number of the sleeve 32 can also be two, and the two elastic members 315 are respectively sleeved on the two sleeves 32. Alternatively, the driving assembly 3 can also not include the sleeve 32, which is not limited in the present application.

[0290] In some examples, the driving assembly 3 can further include a connecting piece 33, which can be connected between the second ends 3152 of the two elastic pieces 315. In this case, the two elastic pieces 315 are arranged in a spaced manner with their central axes coinciding, the second ends 3152 of the two elastic pieces 315 are close to each other, and the first ends 3151 of the two elastic pieces 315 are away from each other. In some examples, the two elastic pieces 315 and the connecting piece 33 can be an integrally formed structural piece, which is beneficial to increase the structural strength and stability of the structure formed by the two elastic pieces 315 and the connecting piece 33. In other embodiments, the two elastic pieces 315 and the connecting piece 33 can also be an integrally formed structure by assembly, which is not limited in the present application. In other embodiments, the driving assembly 3 can also not include the connecting piece 33, which is not limited in the present application.

[0291] Please refer to FIG. 24A, FIG. 24B, FIG. 27 and FIG. 28, FIG. 27 is a sectional structure schematic view of the driving assembly 3 shown in FIG. 24A at K-K, and FIG. 28 is a sectional structure schematic view of the driving assembly 3 shown in FIG. 24A at L-L.

[0292] In some embodiments, the two driving groups 31 can be arranged along the second direction X, the worm 312 in each driving group 31 can be fixedly connected to the output shaft 3111 of the motor 311, the turbine 313 can be engaged with the worm 312, and the elastic piece 315 can be connected to the turbine 313.

[0293] In some examples, the worm 312 can be sleeved on the outside of the output shaft 3111 of the motor 311, and the worm 312 can rotate with the output shaft 3111 of the motor 311. In this case, the hole wall of the mounting hole 3121 of the worm 312 can have a first abutting surface 3121a, and the outer surface of the output shaft 3111 of the motor 311 can have a second abutting surface 3111a, and the first abutting surface 3121a can abut against the second abutting surface 3111a. By arranging the first abutting surface 3121a to abut against the second abutting surface 3111a, the relative rotation between the output shaft 3111 and the worm 312 can be prevented when the motor 311 is working, and the “slip” phenomenon can be avoided, which is beneficial to improve the transmission efficiency of the output shaft 3111 of the motor 311. In some examples, the first abutting surface 3121a and the second abutting surface 3111a can both be planar.

[0294] Exemplarily, the incomplete tooth portion 3133a of the worm wheel 313 can engage with the helical tooth of the worm 312, and the worm 312 drives the worm wheel 313 to rotate when the worm 312 rotates. The rotation axis of the worm wheel 313 can be the axis of the first shaft hole 3131, and the rotation axis of the worm wheel 313 can be parallel to the second direction X. The output shaft 3111 of the motor 311 and the rotation axis of the worm 312 can be parallel to the first direction Y. The rotation axes of the two worm wheels 313 can be arranged in a same line. The abutting blocks 3135 of the two worm wheels 313 are close to each other, and the transmission portions 3132 of the two worm wheels 313 are away from each other. The stop surfaces 3134a of the two worm wheels 313 are oriented in the same direction and can be arranged in a same plane. The contact surfaces 3135a of the two worm wheels 313 are oriented in the same direction and can be arranged in a same plane.

[0295] Exemplarily, the two elastic members 315 are arranged between the two worm wheels 313, and the sleeve 32 is also arranged between the two worm wheels 313. The central axis of the elastic member 315 can be parallel to the rotation axes of the two worm wheels 313. The first end 3151 of the elastic member 315 can abut against the contact surface 3135a of the worm wheel 313. When the worm wheel 313 rotates, the first end 3151 of the elastic member 315 can drive the elastic member 315 to rotate. At this time, the stop surface 3134a is located on the side of the worm wheel 313 away from the elastic member 315.

[0296] Exemplarily, the two drive groups 31 can have a symmetrical structure. In the embodiment, the two drive groups 31 can be symmetrical about a plane, and the plane can be parallel to the YZ plane, and the two drive groups 31 are located on two sides of the plane. That is, the two elastic members 315, the two worm wheels 313, the two motors 311 and the two worms 312 can have a symmetrical structure, and the plane can be parallel to the YZ plane. In other embodiments, the two drive groups 31 can have other arrangement modes, such as a partial symmetrical structure or an array structure, which are not limited in the application. When the two drive groups 31 have a partial symmetrical structure, the motor 311, the worm 312 of the two drive groups 31 are of the same structure, the incomplete tooth portion 3133a of the two worm wheels 313 is of the same structure, and the remaining parts have a symmetrical structure.

[0297] Please refer to FIG. 3A, FIG. 29 and FIG. 30, FIG. 29 is a structural schematic diagram of the lifting mechanism 10 shown in FIG. 3A from another perspective, and FIG. 30 is a structural schematic diagram of the lifting mechanism 10 shown in FIG. 3A after removing the base 1.

[0298] In some embodiments, the driving assembly 3 is mounted on the base 1 and connected with the transmission assembly 4. Two driving assemblies 31 can correspond to two first mounting spaces 131 of the base 1 respectively (as shown in FIG. 5A), and the motor 311 can be mounted at the opening of the base 1, and the turbine 313, the worm 312 and the elastic member 315 can pass through the first mounting space 131 and be accommodated in the accommodating space 11. The driving assembly 3 is arranged close to the first end 4111 of the long rod 411 relative to the second end 4112 of the long rod 411. For example, the motor mounting plate 314 can be fixed to the first fixed part 13 of the base 1 by fasteners to achieve the mounting of the driving assembly 3. For example, the fasteners can be but are not limited to screws, bolts, rivets and the like. In other embodiments, the motor mounting plate 314 can also be connected to the base 1 by other means, which is not limited in the present application.

[0299] Please refer to FIGS. 30-31A, and FIG. 31A is a sectional view of the lifting mechanism 10 shown in FIG. 3A at M-M.

[0300] In some embodiments, the two turbines 313 and the elastic member 315 can be located between the two short rods 421, and the two worms 312 are located at the bottom side of the two turbines 313. The turbine 313 can be rotatably connected to the base 1 and drivingly connected to the transmission assembly 4. For example, the first rotating shaft 446 can pass through the first rotating part 4211 of the short rod 421, the turbine 313, the second fixed part 14 of the base 1 and the elastic member 315 to mount the turbine 313, the short rod 421 and the elastic member 315 to the base 1. At this time, the driving assembly 3 can be connected to the base 1 and the transmission assembly 4 through the first rotating shaft 446, and has high connection reliability and stability. In the present embodiment, the first rotating shaft 446 passes through the first rotating hole 4211a of the first rotating part 4211, the first shaft hole 3131 of the turbine 313 and the first rotating shaft hole 141 of the second fixed part 14, at this time, the rotating axis of the turbine 313 relative to the base 1, the rotating axis of the short rod 421 relative to the base 1 and the central axis of the first rotating shaft 446 coincide, that is, the turbine 313 and the short rod 421 can be regarded as rotating relative to the base 1 with the central axis of the first rotating shaft 446 as the rotating axis.

[0301] For example, the sleeve 32 is sleeved on the first rotating shaft 446, and the two elastic members 315 are sleeved on the sleeve 32 to make the two elastic members 315 sleeved on the first rotating shaft 446. The central axis of the two elastic members 315 coincides with the central axis of the first shaft hole 3131, that is, the central axis of the two elastic members 315 can coincide with the rotating axis of the turbine 313 relative to the base 1 and the central axis of the first rotating shaft 446. In some other embodiments, the driving assembly 3 can also not be provided with the sleeve 32, and the two elastic members 315 can be directly sleeved on the first rotating shaft 446.

[0302] For example, the second fixing portion 14 of the base 1 can be at least partially located in the accommodating groove 3133b of the worm wheel 313, and the two can be in a clamped state, thereby facilitating the reliability and structural stability of the connection between the worm wheel 313 and the base 1, and the arrangement structure of the worm wheel 313 and the base 1 is compact, and the space utilization rate of the lifting mechanism 10 is also improved, which is conducive to the miniaturization of the lifting mechanism 10.

[0303] Please refer to FIG. 31B, which is a schematic view of the cross-sectional structure of FIG. 3A at N-N.

[0304] For example, the output shaft 3111 of the motor 311 can be inserted into the base 1 and can rotate relative to the base 1. For example, the output shaft 3111 can pass through the third fixing portion 15 of the base 1, and the worm 312 can be located between the two protrusions of the third fixing portion 15. By inserting the output shaft 3111 of the motor 311 into the third fixing portion 15, the third fixing portion 15 can support the output shaft 3111 of the motor 311, thereby facilitating the reliability and stability of the connection structure between the driving assembly 3 and the base 1.

[0305] For example, the extension direction of the output shaft 3111 of the motor 311 can be perpendicular to the rotation axis of the worm wheel 313 relative to the base 1, the extension direction of the output shaft 3111 of the motor 311 can be parallel to the first direction Y, and the direction of the rotation axis of the worm wheel 313 relative to the base 1, i.e., the direction of the central axis of the first rotation shaft 446, can be parallel to the second direction X. It can be understood that in the embodiment of the present application, during the process of driving the lifting member 2 to lift relative to the base 1 by the driving assembly 3 through the transmission assembly 4, when the motor 311 works, the output shaft 3111 of the motor 311 can drive the worm 312 sleeved thereon to rotate, thereby driving the worm wheel 313 engaged with the worm 312 to rotate, so that the transmission assembly 4 drivingly connected with the worm wheel 313 and the lifting member 2 drivingly connected with the transmission assembly 4 are forced to move. In the embodiment of the present application, by setting the extension direction of the output shaft 3111 of the motor 311 perpendicular to the rotation axis of the worm wheel 313 relative to the base 1, the energy loss caused by the connection within the lifting mechanism 10 can be reduced, and the transmission efficiency of the motor 311 can be effectively improved.

[0306] In the embodiments of the present application, the motor 311 is connected with the worm 312 through the turbine 313, and the turbine 313 is drivingly connected with the transmission assembly 4, so that the energy of the motor 311 can be transmitted, the transmission structure of the turbine 313 and the worm 312 is simple and compact, the number of structural members or components used for transmission between the motor 311 and the transmission assembly 4 is reduced, the engagement between the turbine 313 and the worm 312 is continuous, the transmission is relatively stable, and it is beneficial to realize the stable and rapid lifting process of the lifting member 2. In other embodiments, the turbine 313 and the worm 312 can not be used for transmission between the motor 311 and the transmission assembly 4, and other ways such as multi-link 43 cooperation or multi-gear engagement can also be used, which is not limited in the present application.

[0307] Please refer to FIGS. 32A-33B, FIG. 32A is a sectional structure schematic view of the lifting mechanism 10 shown in FIG. 3A at O-O, FIG. 32B is a sectional structure schematic view of the lifting mechanism 10 shown in FIG. 3A at P-P, FIG. 33A is a sectional structure schematic view of the lifting mechanism 10 shown in FIG. 3B at Q-Q, and FIG. 33B is a sectional structure schematic view of the lifting mechanism 10 shown in FIG. 3B at R-R.

[0308] In some embodiments, the elastic members 315 can be connected between the turbine 313 and the transmission assembly 4. For example, the first end 3151 of the elastic member 315 can be connected with the turbine 313, and the second end 3152 of the elastic member 315 can be oppositely arranged and connected with the short support rod 422. The first end 3151 of the two elastic members 315 can abut against the contact surface 3135a of the two turbines 313 respectively, and the second end 3152 of the two elastic members 315 can abut against the second abutting surface 4223a of the short support rod 422. When the turbine 313 rotates in the direction of abutting against the first end 3151 of the elastic member 315 (for example, the normal direction of the contact surface 3135a of the turbine 313 towards the elastic member 315), the second end 3152 of the elastic member 315 also rotates and pushes the short support rod 422 to rotate, so as to drive the transmission assembly 4 to move, thereby realizing the driving connection between the turbine 313 and the transmission assembly 4.

[0309] In the embodiments of the present application, the motor 311 can drive the turbine 313 to rotate in the first rotation direction A1, for example, the first rotation direction A1 can be the direction of the turbine 313 abutting against the first end 3151 of the elastic member 315.

[0310] For example, when the lifting mechanism 10 changes from the retracted state to the extended state, the motor 311 can drive the turbine 313 to rotate in the first rotation direction A1, and the turbine 313 can drive the transmission assembly 4 to move through the elastic member 315, so as to drive the lifting member 2 to rise.

[0311] Specifically, the turbine 313 can drive the short support rod 422 to move through the elastic member 315, drive the two short rods 421 to move, and drive the lifting member 2 to rise. The elastic member 315 is connected between the turbine 313 and the short support rod 422. When the turbine 313 rotates in the first rotation direction A1, the short support rod 422 can be driven to move through the elastic member 315. The short support rod 422 is driven by the clockwise driving force F1. The short rod 421 moves, and the short rod 421 drives the long rod 411 to move through the connecting rod 43. The short rod 421 and the long rod 411 simultaneously drive the lifting member 2 to rise. The movement process of the short rod 421 and the long rod 411 can refer to FIGS. 16A, 16B, and the related content described above, which will not be described here.

[0312] In the above embodiment, the elastic member 315 is connected between the turbine 313 and the first rotation part 4211 of the short rod 421. In other embodiments, the elastic member 315 can be directly connected to the first rotation part 4211 of the short rod 421.

[0313] Specifically, the connecting member 33 is connected to the second end 3152 of the two elastic members 315. The connecting member 33 can abut against the short support rod 422. The two elastic members 315 apply forces to the short support rod 422 through the connecting member 33. This can improve the transmission efficiency and reliability of the elastic member 315 driving the short support rod 422 to move. This can also reduce the adverse effects of stress concentration on the service life of the elastic member 315 and the short support rod 422.

[0314] Please refer to FIGS. 34A-35B. FIG. 34A is a sectional view of the lifting mechanism 10 shown in FIG. 3A at S-S. FIG. 34B is a sectional view of the lifting mechanism 10 shown in FIG. 3A at T-T. FIG. 35A is a sectional view of the lifting mechanism 10 shown in FIG. 3B at U-U. FIG. 35B is a sectional view of the lifting mechanism 10 shown in FIG. 3B at V-V.

[0315] In some embodiments, the two turbines 313 can be respectively connected to the two short rods 421. When the turbine 313 rotates, the short rod 421 can be forced to move to achieve the transmission connection between the turbine 313 and the transmission assembly 4. For example, the gear surface 3134a of the turbine 313 can contact the first abutting surface 4211c of the first rotating part 4211 of the short rod 421. When the turbine 313 rotates towards the first abutting surface 4211c (for example, the normal direction of the gear surface 3134a of the turbine 313 towards the first rotating part 4211), the short rod 421 is pushed to rotate to drive the transmission assembly 4 to move, thereby achieving the transmission connection between the turbine 313 and the transmission assembly 4.

[0316] In some embodiments, the transmission connection between the turbine 313 and the short rod 421 can be achieved by surface contact, which can save the structure for transmission between the turbine 313 and the short rod 421, and can improve the reliability of the transmission connection between the turbine 313 and the short rod 421. In other embodiments, the gear surface 3134a and the first abutting surface 4211c can not be completely matched, and the transmission connection between the turbine 313 and the short rod 421 can be achieved by line-surface contact, which is not limited in the present application.

[0317] In some embodiments, at least part of the transmission part 3132 of the turbine 313 can be located in the recessed space 4211b of the first rotating part 4211 of the short rod 421, and at least part of the first rotating part 4211 of the short rod 421 can be located in the first recess 3134, and the cooperation structure is compact.

[0318] In some embodiments of the present application, the motor 311 can drive the turbine 313 to rotate in the second rotating direction A2, and the second rotating direction A2 is opposite to the first rotating direction A1. For example, the second rotating direction A2 can be the direction in which the turbine 313 presses the first abutting surface 4211c of the short rod 421.

[0319] When the lifting mechanism 10 changes from the extended state to the retracted state, the motor 311 drives the turbine 313 to rotate in the second rotating direction A2, and the turbine 313 can contact and push the transmission assembly 4 to move to drive the lifting member 2 to descend.

[0320] Specifically, the two turbines 313 can respectively push the two short rods 421 to move to drive the lifting member 2 to descend. The gear position surface 3134a of the turbine 313 can contact the first abutting surface 4211c of the first rotating part 4211 of the short rod 421. When the turbine 313 rotates in the second rotating direction A2, the gear position surface 3134a of the turbine 313 can push against the first abutting surface 4211c, the short rod 421 is subjected to the counterclockwise retracting force F2, the short rod 421 moves, and the short rod 421 drives the long rod 411 to move through the connecting rod 43, and the short rod 421 and the long rod 411 simultaneously drive the lifting member 2 to descend. The movement process of the short rod 421 and the long rod 411 can refer to FIGS. 18A and 18B and the related content described above, which will not be described here.

[0321] In the embodiment, since the gear position surface 3134a of the turbine 313 contacts the first abutting surface 4211c of the first rotating part 4211, it can also be considered that the turbine 313 directly contacts the first rotating part 4211 of the short rod 421, and the turbine 313 can directly drive the first rotating part 4211 to move in the descending process of the lifting member 2. In other embodiments, the turbine 313 and the first rotating part 4211 can also be indirectly connected through other structural members.

[0322] In the embodiment, in the descending process of the lifting member 2, the force transmission does not need to rely on the deformation and deformation recovery of the elastic member 315, the force transmission speed is faster in the descending process, which is beneficial to the rapid descent of the lifting member 2.

[0323] In some embodiments, in the retracted state, the elastic member 315 is in a compressed state, and the forces among the elastic member 315, the turbine 313 and the short balance rod 42 are balanced, so that the lifting mechanism can maintain the retracted state, which is beneficial to improve the stability and reliability of the lifting mechanism.

[0324] It can be understood that, in the retracted state, the elastic member 315 is in a compressed state, the first end 3151 of the elastic member 315 abuts against the contact surface 3135a of the turbine 313, and the direction of the force of the elastic member 315 on the turbine 313 can be opposite to the direction in which the turbine 313 presses the first end 3151 of the elastic member 315 (i.e., the second rotating direction A2); similarly, the second end 3152 of the elastic member 315 abuts against the second abutting surface 4223a of the short support rod 422, and the direction of the force of the elastic member 315 on the short support rod 422 can be the first rotating direction A1, and the magnitudes of the forces are equal.

[0325] The turbine 313 is pressed against the first rotating part 4211 of the short lever 421 under the action of the elastic member 315, so that the first rotating part 4211 is also subjected to the action force in the second rotating direction A2, that is, the short lever 421 of the short balance lever 42 is subjected to the action force of the turbine 313 in the second rotating direction A2, and the size of the action force is equal to the size of the action force of the elastic member 315 on the short supporting lever 422 in the first rotating direction A1, and the directions are opposite, so that the short balance lever 42 is balanced. It can also be said that in the retracted state, the action force between the short balance lever 42, the turbine 313 and the elastic member 315 is balanced, and when not subjected to external force (for example, the driving force of the driving assembly 3), the short balance lever 42, the turbine 313 and the elastic member 315 can remain relatively static, so that the lifting mechanism can remain in the retracted state. Similarly, the stress condition of the turbine 313 and the elastic member 315 in the retracted state can be obtained, which is not described here.

[0326] In the embodiment of the present application, the two driving assemblies 31 are respectively connected to the two groups of transmission members 44, and the two motors 311 can work simultaneously to drive the lifting mechanism 10, so that the driving force is larger and the driving efficiency is higher, which is beneficial to realize faster lifting process of the lifting mechanism 10.

[0327] In some embodiments, due to factors such as driving sequence, process manufacturing, wear and aging degree, the two motors 311 in the two driving assemblies 31 may have different control deviations on the movement process of the structural members (such as the worm 312) connected thereto, thereby causing movement deviations between the two driving assemblies 31 in the lifting mechanism, and also causing movement deviations between the two groups of transmission members 44 and other structural members connected with the driving assemblies 31, thereby affecting the reliability and smoothness of the movement of the lifting mechanism. In the embodiment of the present application, the elastic member 315 is arranged in the driving assembly 31, and the compression degrees of the elastic members 315 in the two driving assemblies 31 can be different, which is used to eliminate the influence of the movement deviations of the two driving assemblies 31 on the lifting process of the lifting mechanism 10, and is beneficial to improve the synchronization of the work of the two driving assemblies 31.

[0328] It can be understood that, for example, the two turbines 313 in the lifting mechanism 10 can include a first turbine and a second turbine, and the two elastic members 315 can include a first elastic member and a second elastic member, the first elastic member is connected between the first turbine and the short supporting lever 422, and the second elastic member is connected between the second turbine and the short supporting lever 422.

[0329] For example, the first turbine and the second turbine are respectively driven by the motors 311 of the two groups of driving groups 31. When the lifting mechanism 10 changes from the retracted state to the extended state, the rotation angle of the first turbine in the first rotation direction A1 can be greater than the rotation angle of the second turbine in the first rotation direction A1. At this time, the compression degree of the first elastic member is greater than the compression degree of the second elastic member. The distance between the abutting protrusion 3135 of the first turbine and the short support rod 422 is less than the distance between the abutting protrusion 3135 of the second turbine and the short support rod 422. During the movement, the two ends of the first elastic member can respectively abut between the abutting protrusion 3135 of the first turbine and the short support rod 422, and keep in contact with the first turbine and the short support rod 422. The second elastic member can be appropriately deformed to adapt to the difference in the distance between the two turbines 313 and the short support rod 422, so that the two ends of the second elastic member can also keep in contact with the abutting protrusion 3135 of the second turbine and the short support rod 422.

[0330] Wherein, as known from the foregoing, the short balance rod 42 is subjected to the force of the turbine 313 and the elastic member 315. When the rotation angles of the two turbines 313 are different, and the first rotation parts 4211 of the two short rods 421 have the same connection rotation angle due to the short support rod 422, the distance between the gear position surface 3134a of the two turbines 313 and the first abutting surface 4211c of the short balance rod 42 is different. The compression degree of the elastic member 315 in the two driving groups 31 can be different, so as to avoid the mutual influence of the elastic member 315, the turbine 313 or the short balance rod 42, thereby avoiding the problems such as jamming of the mechanism, and thus affecting the smoothness of the lifting process of the lifting mechanism 10.

[0331] Wherein, by setting the two driving groups 31 as symmetrical structures, the synchronization of the working of the two driving groups 31 is further improved, which is beneficial to improve the driving efficiency.

[0332] Please refer to FIG. 36, which is a sectional structure schematic diagram of the lifting mechanism 10 shown in FIG. 3A.

[0333] In some embodiments, the lifting mechanism 10 is in the extended state, and when the lifting member 2 is subjected to external pressure, the lifting member 2 is lowered, the transmission assembly 4 moves, and the elastic member 315 is deformed. For example, in the extended state, the lifting member 2 is subjected to external pressure F3 in the negative direction-Z of the third direction (see F3 in FIG. 36), the pressure F3 drives the lifting member 2 to retract in the negative direction-Z of the third direction, thereby driving the long rod 411 to rotate counterclockwise around the first connecting shaft 441 (as shown in FIG. 15A), and driving the short rod 421 to rotate counterclockwise around the first rotating shaft 446, and the short supporting rod 422 presses the elastic member 315. The elastic member 315 can buffer the pressure F3 by deformation in this process, avoiding hard impact on the lifting member 2. In addition, the turbine 313 can maintain the original state and position, avoiding accidental structural impact of the turbine 313, the worm 312, and the motor 311, to protect the driving assembly 3.

[0334] In addition, after the pressure F3 on the lifting member 2 is removed, the elastic member 315 can drive the short rod 421 and the long rod 411 to rotate together by the restoring force of deformation, to drive the lifting member 2 to recover to the extended state. The pressure F3 can come from the falling of the electronic device 1000, the impact of the electronic device 1000 on the outside world, the extrusion of the electronic device 1000 on the outside world, and the like.

[0335] In the foregoing embodiments, the connection member 33 is connected between the two elastic members 315, and the driving assembly 3 is designed accordingly. In other embodiments, the driving assembly 3 can not include the connection member 33. At this time, the second ends 3152 of the two elastic members 315 are independent of each other, which is beneficial to improve the freedom of deformation of the two elastic members 315 and the synchronization of the two driving assemblies 31. The second ends 3152 of the two elastic members 315 can be spaced apart from each other to avoid interference. Alternatively, the second ends 3152 of the two elastic members 315 can be in contact.

[0336] In other embodiments, the lifting mechanism 10 can not include the elastic member 315 and the connection member 33, and the relative position of the turbine 313 and the first rotating part 4211 is changed, so that the gear surface 3134a is in contact with the short rod 421 or the short supporting rod 422. When the motor 311 drives the turbine 313 to rotate in the first rotating direction A1, the turbine 313 can drive the short rod 421 or the short supporting rod 422 to move, to drive the lifting member 2 to rise.

[0337] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict, and any combination of the features in different embodiments is within the protection scope of the present application, that is, the above-described multiple embodiments can be combined as needed.

[0338] It should be noted that all the above drawings are exemplary illustrations of the present application, and do not represent the actual size of the product. The size ratio relationship between the components in the drawings is not limited to the actual product of the present application.

[0339] The above are only some embodiments and implementations of the present application, and the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application.
