Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a lifting mechanism, a camera device and an electronic device. Background Art

[0002] As the camera function of electronic devices matures, users' demand for telephoto lenses is also increasing. For example, electronic devices with camera functions such as mobile phones and tablets usually require telephoto shooting functions. For the increasingly thin electronic devices, the integration of telephoto lenses cannot be separated from a retractable lifting mechanism.

[0003] The existing lifting mechanism mainly adopts spiral groove drive and inclined groove drive. The main problem of this solution is that when the lifting mechanism is lifting, the guide of the lifting part is unstable and it is easy to get stuck.

[0004] Therefore, how to improve the telescopic smoothness of the lifting mechanism becomes a technical problem that needs to be solved. Summary of the invention

[0005] The purpose of the present application is to provide a lifting mechanism, a camera device and an electronic device. The lifting mechanism has a connecting rod assembly with a four-link structure, which helps to improve the smoothness of the extension and retraction of the lifting mechanism.

[0006] In a first aspect, the present application provides a lifting mechanism that can be applied to a camera device including a camera module. The lifting mechanism includes a base, a lifting member, and a connecting rod assembly, and the lifting member and the connecting rod assembly are both movably mounted on the inner side of the base. The base has a first fixing portion and a second fixing portion that are spaced apart.

[0007] The connecting rod assembly includes a long rod, a short rod and a connecting rod. The first end of the long rod is rotatably connected to the first fixed part, the second end of the long rod is rotatably connected to the first end of the lifting member, and the long rod includes a transition part, which is located between the first end of the long rod and the second end of the long rod. The short rod includes a first rotating part, a second rotating part and a third rotating part fixed to each other, the first rotating part is rotatably connected to the second fixed part, the second rotating part is slidably connected or rotatably connected to the second end of the lifting member, and the second end of the lifting member is close to the first end of the long rod relative to the first end of the lifting member. The first end of the connecting rod is rotatably connected to the transition part, and the second end of the connecting rod is rotatably connected to the third rotating part.

[0008] When the short rod is subjected to force and moves, the short rod and the long rod jointly drive the lifting member to move up and down relative to the base.

[0009] In the present application, the portion between the first fixed part and the second fixed part of the base can be regarded as the fixed rod of the base. The long rod can include a first section and a second section that are fixedly connected. The first section of the long rod is the line connecting the rotation connection center between the first end of the long rod and the first fixed part and the rotation connection center between the adapter and the first end of the connecting rod. The second section of the long rod is the line connecting the rotation connection center between the adapter and the first end of the connecting rod and the rotation connection center between the second end of the long rod and the first end of the lifting member. The short rod can include a first section and a second section that are fixedly connected. The first section of the short rod is the line connecting the rotation connection center between the first rotating part and the second fixed part and the rotation center of the third rotating part. The second section of the short rod is the line connecting the rotation center of the third rotating part and the rotation connection center of the second rotating part and the second end of the lifting member. The fixed rod, the first section of the long rod, the connecting rod and the first section of the short rod are connected end to end in rotation in sequence to form a four-bar linkage. The second section of the long rod and the second section of the short rod can be lifted and lowered together with the movement of the four-bar linkage. The four-bar linkage improves the telescopic smoothness of the lifting mechanism.

[0010] In some possible implementations, the connecting rod assembly includes a long balancing rod and a short balancing rod, the long balancing rod includes a long support rod and two long rods, the two long rods are arranged opposite to each other and are respectively located on both sides of the lifting member, and the first ends of the two long rods are respectively fixed to the two ends of the long support rod. The short balancing rod is located between the two long rods, the short balancing rod includes a short support rod and two short rods, the two short rods are arranged opposite to each other and are respectively connected to the two ends of the short support rod. The connecting rod assembly includes two sets of transmission parts arranged symmetrically, each set of transmission parts includes a long rod, a short rod and a connecting rod.

[0011] In this implementation, since the two groups of transmission members are connected by the long support rod and the short support rod, the two groups of four-bar linkages can move simultaneously. Driven by the two short rods, the first side and the second side of the lifting member can be lifted and lowered simultaneously, so that the second end of the lifting member can be lifted and lowered smoothly. Driven by the two long rods, the first side and the second side of the first end of the lifting member can be lifted and lowered simultaneously, so that the first end of the lifting member can be lifted and lowered smoothly. Driven by the two short rods and the two long rods, the first end and the second end of the lifting member can be lifted and lowered simultaneously, so that the overall lifting of the lifting member can be lifted and lowered smoothly. Therefore, by driving the two groups of four-bar linkages at the same time, the two sides of the lifting member can be driven to lift and lower at the same time, thereby improving the lifting stability of the lifting member.

[0012] The two groups of transmission members may be symmetrically connected to the first side of the lifting member and the second side of the lifting member.

[0013] In this implementation, the two long rods are fixedly connected by the long support rod, so that the two second rotation shafts rotatably connected to the two sides of the first end of the lifting member are located on the long balance rod, so that the two second rotation shafts can move synchronously, and the lifting balance of the lifting member on the first side and the second side of the first end is achieved, thereby improving the lifting smoothness of the lifting member. The two short rods are fixedly connected by the short support rod, so that the two second rotation shafts slidably connected to the two sides of the second end of the lifting member are located on the short balance rod, so that the two second rotation shafts can move synchronously, and the lifting balance of the lifting member on the first side and the second side of the second end is achieved.

[0014] In this implementation, since in each group of transmission members, the connecting rods correspondingly rotate to connect a long rod and a short rod, the long rod and the short rod in each group of transmission members can move synchronously. Therefore, on the first side of the lifting member, the second rotating shaft and the second rotating shaft can move synchronously to achieve the lifting balance of the first end and the second end of the first side of the lifting member. On the second side of the lifting member, the second rotating shaft and the second rotating shaft can move synchronously to achieve the lifting balance of the first end and the second end of the second side of the lifting member.

[0015] In some possible implementations, the lifting mechanism has a retracted state and an extended state. In the retracted state, the lifting member is in an initial position relative to the base. In the extended state, the lifting member rises to an extended position relative to the base. The axis of the lifting member in the initial position coincides with the axis in the extended position.

[0016] In this implementation, the axis of the lifting member coincides with 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 is not offset in the direction perpendicular to the optical axis of the lifting member, and the optical axis of the lifting member can be kept without offset, thereby ensuring the lighting quality of the camera module located in the inner space of the lifting member, thereby ensuring the camera quality of the camera device.

[0017] In the retracted state, when the first section of the short rod is driven by a clockwise force, the first section of the short rod can rotate in the clockwise direction and drive the second section of the short rod to rotate in the clockwise direction, thereby driving the second end of the lifting member to rotate in the clockwise direction to achieve the lifting of the second end of the lifting member. At the same time, the short rod also drives the first section of the long rod to rotate in the clockwise direction through the connecting rod, so that the first section of the long rod drives the second section of the long rod to rotate in the clockwise direction, thereby driving the first end of the lifting member to rotate in the clockwise direction to achieve the lifting of the first end of the lifting member, thereby achieving the overall lifting of the lifting member.

[0018] In the extended state, when the first section of the short rod is subjected to a counterclockwise retraction force, the first section of the short rod can rotate counterclockwise and drive the second section of the short rod to rotate counterclockwise, thereby driving the second end of the lifting member to rotate counterclockwise to achieve the second end of the lifting member to descend. At the same time, the short rod also drives the first section of the long rod to rotate counterclockwise through the connecting rod, so that the first section of the long rod drives the second section of the long rod to rotate counterclockwise, thereby driving the first end of the lifting member to rotate counterclockwise to achieve the first end of the lifting member to descend, thereby achieving the overall descent of the lifting member.

[0019] In some possible implementations, a line connecting the position of the second end of the long rod in the retracted state and the position of the second end in the extended state is parallel to the axial direction of the lifting member when it is in the initial position.

[0020] In this implementation, the lifting member extends from the initial position to the extended position, and the lifting member does not rotate around the axis of the lifting member, so that the lifting member moves stably during the conversion between the extended state and the retracted state.

[0021] In some possible implementations, a first rotating hole is provided at the first end of the long rod, and the long rod is rotatably connected to the first fixing portion through the first rotating hole, and a second rotating hole is provided at the second end of the long rod, and the long rod is rotatably connected to the first end of the lifting member through the second rotating hole. In the retracted state, the first rotating hole is closer to the top side of the lifting member than the second rotating hole.

[0022] The long rod may include a first rod, a second rod and a third rod. The first rod, the second rod and the third rod are connected in sequence along the direction from the first end of the long rod to the second end. The first end of the long rod and the adapter may be located on the first rod, and the second end of the long rod may be located on the third rod. The first end of the long rod may be provided with a first rotation hole, the second end of the long rod may be provided with a second rotation hole, and the adapter may be provided with a third rotation hole.

[0023] In the present implementation, since the axis of the first rotating hole is the rotation center of the long rod, and the height of the first rod of the long rod is greater than the height of the third rod, by setting the first rotating hole higher than the second rotating hole, when the connecting rod assembly drives the lifting member to rise, the third rod can move in the rising direction and utilize the height dimension of the first rod, thereby reducing the size space occupied by the lifting mechanism in the height direction while keeping the movement stroke of the lifting member unchanged, which is conducive to the lightweight design of the lifting mechanism.

[0024] The bottom side of the long rod is a plane. The height of the first rod is greater than the size of the second rod, and the height of the second rod is greater than the size of the third rod.

[0025] In this implementation, the height of the first rod is high, so that the adapter can provide more installation space.

[0026] Among them, the height of the third rod gradually decreases from the first end of the long rod to the second end of the long rod, so that the top side of the third rod is an inclined surface, thereby reducing the height dimension of the second end of the long rod, making the weight of the long rod light, thereby reducing the power consumption required to drive the long rod to move, and improving the movement flexibility of the long rod.

[0027] The long support rod can be fixed between the first rods of the two long rods, so that the long support rod is fixed at the position where the structural strength of the long rods is the strongest, thereby improving the overall structural strength of the long balance rod.

[0028] The height of the long support rod is smaller than the size of the first rod, and the long support rod can be fixed to the part of the first rod close to the bottom side, so that there is a receiving space between the two first rods, which can be used to install other components, thereby improving space utilization.

[0029] In some possible implementations, the lifting member has a sliding groove, and the sliding groove is provided at the second end of the lifting member. The connecting rod assembly also includes a second rotating shaft, the second rotating shaft is fixedly connected or rotationally connected to the second rotating part, at least a part of the second rotating shaft is located in the sliding groove, and the second rotating shaft can slide along the extension direction of the sliding groove.

[0030] In this implementation, the size of the sliding groove in the extension direction is set to be larger than the outer diameter of the second rotating shaft, so that during the lifting process of the lifting member, the second rotating shaft can move in the sliding groove along the extension direction of the sliding groove, thereby eliminating the height movement deviation between the first end and the second end of the lifting member during the lifting process, thereby improving the smoothness of the lifting movement of the lifting member.

[0031] The difference between the dimension of the sliding groove in the extension direction and the outer diameter of the second rotating shaft is in the range of 0 mm to 0.08 mm. For example, the difference in dimension may be, but is not limited to, 0.01 mm, 0.03 mm, 0.05 mm, 0.07 mm, 0.08 mm, or other values ​​in the range of 0.01 mm to 0.08 mm.

[0032] In some possible implementations, the sliding groove is a linear groove, and the extending direction of the sliding groove is perpendicular to the axis of the lifting member.

[0033] In this implementation, the sliding groove can be a straight groove, and the extension direction of the sliding groove is perpendicular to the axis of the lifting member, which is conducive to the consistency of the height of the first end and the second end of the lifting member, so that the lifting stroke of the first end and the second end of the lifting member is consistent, thereby improving the stability of the lifting member.

[0034] In some other possible implementations, the sliding groove can also be an arc groove or a spline curve groove, which is specifically designed according to the movement path of the second rotating shaft during the lifting process of the lifting member, as long as the lifting strokes of the first end and the second end of the lifting member can be consistent.

[0035] In some possible implementations, the lifting member has a second avoidance groove, and the second avoidance groove is arranged around the outer circumference of the lifting member.

[0036] In this implementation, the second avoidance groove is used to avoid other structural parts, such as decorative parts, during the lifting process of the lifting member to avoid collision, damage or affecting the lifting accuracy, so as to avoid collision of the lifting member during the lifting process.

[0037] The lifting member may include a first lifting cylinder and a second lifting cylinder. The first lifting cylinder and the second lifting cylinder are coaxial and stacked along the axial direction of the lifting member. The lifting member may have two first avoidance grooves, which are arranged opposite to each other on the side of the first lifting cylinder. The second avoidance groove is arranged around the outer circumference of the second lifting cylinder. The opening of the first avoidance groove of the lifting member faces the long rod, and the first avoidance groove can accommodate part of the long rod in the retracted state.

[0038] In this implementation, in the retracted state, since the lifting member can avoid the long rod through the first avoidance groove, the arrangement of the lifting member and the connecting rod assembly is more compact, the size of the lifting mechanism can be reduced, which is conducive to realizing a lightweight design of the electronic device.

[0039] In some possible implementations, the first rotating part and the third rotating part are located on a side of the second rotating part away from the lifting member, and the third rotating part is located at the bottom of the first rotating part. The line connecting the first rotating part and the third rotating part is arranged at an angle to the line connecting the second rotating part and the third rotating part.

[0040] In this implementation, the line connecting the first rotating part and the third rotating part and the line connecting the second rotating part and the third rotating part are arranged at an angle, which is beneficial for the short rod to match the motion and space requirements of the four-bar linkage.

[0041] The angle is in the range of 30° to 120°. For example, the angle may be, but is not limited to, 30°, 50°, 70°, 90°, 110°, 120°, or other angle values ​​between 30° and 120°.

[0042] In some possible implementations, the lifting mechanism further includes a driving assembly, which is transmission-connected to the short support rod, and the driving assembly is used to drive the short support rod so that the short rod moves under force.

[0043] In this implementation, the driving assembly can apply driving force to the short support rod, and drive the short support rod through the driving force to drive the short rod and the long rod, so that the short rod and the long rod jointly drive the lifting member to rise.

[0044] The point of action of the driving force on the short support rod is close to the bottom side of the short support rod, so that the force arm of the driving force is longer, thereby improving the driving efficiency.

[0045] The driving component can apply a retraction force to the short support rod, and pull the short support rod through the retraction force to drive the short rod and the long rod, so that the short rod and the long rod jointly drive the lifting member to descend.

[0046] Among them, the point of action on the short support rod when driving the lifting member to retract is the same as the point of action on the short support rod when the driving connecting rod assembly drives the lifting member to extend, so that the driving assembly of the connecting rod assembly is consistent and can maintain the stable movement of the lifting member to avoid deviation of the lifting member.

[0047] In some possible implementations, the lifting mechanism further includes a buffer assembly, which is connected between the short support rod and the driving assembly, and is used to allow the relative position of the short support rod and the driving assembly to change.

[0048] In this implementation, the buffer assembly can provide a buffering effect for the transmission of force between the drive assembly and the connecting rod assembly. When the lifting mechanism is in the extended state, if the lifting member is retracted due to external pressure, the buffer assembly can play a force buffering role through deformation to relieve part of the force on the lifting member, play a role in protecting the lifting member, and can reduce the force transmitted to the drive assembly, thereby reducing damage to the driving assembly. In addition, after the external pressure on the lifting member is relieved, the buffer assembly can also drive the lifting member to rise and return to the extended state through deformation recovery force.

[0049] In some possible implementations, the short balance bar further includes two limit blocks, which are spaced apart on the side of the short support bar away from the lifting member. The buffer assembly includes a buffer bar, a torsion spring and a buffer shaft, the buffer bar is installed between the two limit blocks, the buffer bar has a receiving groove, the opening of the receiving groove faces the short support bar, the torsion spring is received in the receiving groove, the buffer shaft passes through the limit blocks, the torsion spring and the buffer bar, and the two pins of the torsion spring respectively abut against the short support bar and the bottom wall of the receiving groove.

[0050] In this implementation, since the torsion spring is always in a compressed state, the torsion spring can maintain a certain rigidity, and when the buffer rod is subjected to force to further slowly compress the torsion spring, the torsion spring can quickly return to the initial state to drive the short balance rod. Therefore, when the buffer rod is subjected to force to slowly compress the torsion spring, the buffer assembly and the short balance rod can be regarded as one body and move synchronously when subjected to force.

[0051] The buffer rod may further include a baffle, which is connected to the bottom wall of the receiving groove and extends in a direction away from the receiving groove.

[0052] In this implementation, the baffle can be set corresponding to the pin of the torsion spring close to the bottom wall of the receiving groove, thereby increasing the contact surface between the buffer rod and the pin of the torsion spring when the buffer rod rotates toward the short support rod, which is beneficial to driving the torsion spring to drive the short support rod and improving the force transmission efficiency.

[0053] In some possible implementations, the short balance bar further includes a limiting rib, which is fixed to the limiting block and protrudes in a direction away from the short support bar. Two support blocks are respectively protruded at both ends of the buffer bar, and two pins of the torsion spring elastically abut against the short support bar and the bottom wall of the receiving groove, so that the two support blocks respectively abut against the two limiting ribs.

[0054] In this implementation, the torsion spring is in a compressed state, and the force applied by the torsion spring to the short support rod is opposite to the force direction of the limiting rib force of the buffer rod's support block against the short balance rod. The force applied by the torsion spring to the bottom wall of the buffer rod's receiving groove is opposite to the force direction of the limiting rib force of the short balance rod against the support block of the buffer rod, thereby balancing the forces between the buffer rod and the short balance rod, and maintaining relative stillness when not affected by external forces, which is beneficial to improving the stability of the connection between the buffer rod and the short support rod, thereby improving the transmission stability.

[0055] In this implementation, during the descent of the lifting member, the driving assembly drives the buffer rod to rotate away from the short support rod, and the buffer rod can be supported by the support block to the limit rib, and drive the short support rod to rotate together, thereby driving the lifting member to descend. During the descent of the lifting member, there is no need to rely on the deformation and deformation recovery of the torsion spring to transmit force, so that the force transmission speed during the descent is fast, which is conducive to the rapid descent of the lifting member. In addition, there is no need to stretch the two pins of the torsion spring, which can reduce the force fatigue of the torsion spring, thereby increasing the service life of the torsion spring.

[0056] In some possible implementations, the driving assembly includes a motor, a driving shaft, a crank and a transmission rod, the motor is drivingly connected to the driving shaft, the driving shaft is fixedly connected to the first end of the crank, the second end of the crank is rotationally connected to the first end of the transmission rod, and the second end of the transmission rod is rotationally connected to the buffer rod. The motor is used to drive the crank to rotate, so as to drive the transmission rod to drive the buffer rod to rotate.

[0057] In this implementation, the motor can be directly connected to the crank and used to drive the crank to rotate, thereby improving transmission efficiency.

[0058] The driving assembly may further include a reduction gearbox, and the motor may be connected to the driving shaft via the reduction gearbox.

[0059] In this implementation, the motor and the drive shaft are connected by a reduction gear transmission, so that the high-speed rotation of the motor can be reduced to a suitable rotation speed and output by the drive shaft, thereby improving the speed control of the drive shaft and thus improving the lifting stability of the lifting member.

[0060] In some possible implementations, when the lifting mechanism is in the extended state, an angle α formed by a line connecting the first end of the transmission rod and the second end of the transmission rod and a line connecting the first end of the crank and the second end of the crank is in the range of 180°±10°.

[0061] In this implementation, the transmission rod and the crank are arranged at an angle α, and at this time, the transmission rod and the crank are at the dead point of the mechanism, so that the transmission rod and the crank will not rotate relative to each other, so that the transmission rod and the crank can jointly support the buffer rod. Therefore, the bottom wall of the buffer rod receiving groove can form a support for the torsion spring, and under the action of pressure, the torsion spring will be compressed, and the transmission rod will not drive the crank 35 to rotate, thereby preventing the crank from driving the motor to rotate, and avoiding the motor from passively rotating, so as to protect the motor.

[0062] In addition, the lifting member can descend after being subjected to pressure, and the torsion spring can buffer the pressure by deformation in this process to prevent the lifting member from being hit hard. In addition, after the lifting member descends, the base can provide protection for the lifting member to prevent the lifting member from being further hit. In addition, after the pressure on the lifting member is removed, the torsion spring can drive the short rod and the long rod to rotate together through the force of deformation recovery, so as to drive the lifting member to return to the extended state.

[0063] The value of the angle α may be, but is not limited to, 170°, 175°, 180°, 185°, 190°, or other values ​​between 170° and 190°, as long as the transmission rod and the crank can form a dead point of the mechanism when in the extended state.

[0064] The pressure may come from the falling of the electronic device, the collision between the electronic device and the outside world, the squeezing between the electronic device and the outside world, etc.

[0065] In some possible implementations, the base further has a driving fixing portion, and the driving fixing portion and the first fixing portion are arranged at an interval;

[0066] The driving shaft includes an output shaft and a supporting shaft, which are coaxially arranged. One end of the output shaft is transmission-connected to the motor, and the other end of the output shaft is fixedly connected to the first end of the crank. One end of the supporting shaft is fixedly connected to the first end of the crank, and the other end of the supporting shaft is rotatably connected to the driving fixed part.

[0067] In this implementation, the support shaft can improve the stability of the drive assembly installation, which is beneficial to the stability of the drive assembly transmission. In addition, the support shaft can also pass through the auxiliary fixing hole of the first fixing part of the base, further improving the stability of the drive assembly installation.

[0068] In some possible implementations, a boss is provided on the periphery of the lifting member. The base has an extension limit platform and a retraction limit platform arranged opposite to each other, and the boss is located between the extension limit platform and the retraction limit platform. When the lifting mechanism is in the extended state, the boss abuts against the extension limit platform. When the lifting mechanism is in the retracted state, the boss abuts against the retraction limit platform.

[0069] In this implementation, the retraction limiter is arranged on the bottom side of the base, so that when the lifting member is converted from the extended state to the retracted state, the top side surface of the retraction limiter can limit the lifting member, thereby preventing the lifting member from over-retracting and colliding with other components inside the electronic device. In addition, since the lifting member is in the retracted state in most cases, the retraction limiter can support the lifting member to maintain the overall structural stability of the lifting mechanism.

[0070] In this implementation, the extension limit platform is arranged close to the top side of the base, so that when the lifting member is converted from the retracted state to the extended state, the bottom surface of the extension limit platform can limit the lifting member to avoid excessive extension of the lifting member, ensuring that the extension size of the lifting member is consistent each time, thereby improving the stability of the electronic device in the telephoto state.

[0071] The bottom wall of the trough is connected to the extension limit platform, so that the bottom wall of the trough can be connected to the side wall of the base through the extension limit platform, thereby improving the structural strength of the bottom wall of the trough. The bottom wall of the trough is connected to the extension limit platform, and the limiting area of ​​the extension limit platform is increased, which is conducive to limiting the lifting member.

[0072] In some possible implementations, the lifting mechanism further includes a decorative member, which is mounted on the base. The decorative member surrounds the lifting member and blocks a gap between the lifting member and the base.

[0073] In this implementation, the decorative piece blocks the gap between the base and the lifting piece, thereby playing a role of decoration and improving the appearance. In addition, the decorative piece can also prevent debris, dust, etc. from entering the gap between the base and the lifting piece, playing a role of sealing and dustproofing.

[0074] In some possible implementations, the lifting mechanism also includes a waterproof component, which is installed in the base and surrounds the lifting component. One end of the waterproof component is sealed to the base, and the other end is sealed to the lifting component. The waterproof component can deform to follow the lifting of the lifting component.

[0075] In this implementation, the waterproof component can be located in the gap between the lifting component and the base, so that the waterproof component can be shielded by the decorative component, thereby avoiding direct contact between the waterproof component and the outside air, slowing down the oxidation and corrosion of the waterproof component, and thereby increasing the service life of the waterproof component.

[0076] In this implementation, the waterproof part can be deformed so that it can move up and down together with the lifting part, so that the waterproof component can cover the gap between the lifting part and the base during the lifting of the lifting part, thereby achieving a waterproof and dustproof sealing effect of the lifting part during the lifting process.

[0077] The waterproof assembly may include a first waterproof ring, a second waterproof ring and a waterproof member. The first waterproof ring and the second waterproof ring are connected to both ends of the waterproof member. The first waterproof ring is sleeved on the lifting member and fixed to the limiting surface. The second waterproof ring is fixed to the bottom wall of the sink. The waterproof member is also roughly annular or ring-shaped.

[0078] In this implementation, the first waterproof ring, the second waterproof ring and the waterproof member can block the gap between the lifting member and the base, thereby achieving a waterproof and dustproof sealing effect to protect the internal structure of the electronic device. During the lifting process, the lifting member can drive the first waterproof ring to move together through the limiting surface, and the first waterproof ring can drive the waterproof member to deform.

[0079] In a second aspect, the present application further provides a camera device, comprising a camera module and a lifting mechanism as described above, wherein the camera module is fixedly connected to the lifting mechanism.

[0080] In a third aspect, the present application further provides an electronic device, comprising a housing and a camera device as described above, wherein the housing is provided with a through hole, the camera device is installed in the housing, and a lifting member of a lifting mechanism of the camera device is exposed in the through hole.

[0081] In the present application, the lifting member of the lifting mechanism can be raised from the through hole of the camera decorative member to the extended position, so that the height of the internal space of the lifting mechanism is increased to allow the lens of the camera module or part of the lens of the lens to move in the direction away from the photosensitive element, so as to increase the distance between the lens or part of the lens of the lens and the photosensitive element, increase the focal length of the shooting, and enable the electronic device to achieve telephoto shooting to improve the shooting effect. In addition, since the lifting member can be extended from the through hole, the light incident surface of the camera device protrudes from the camera decorative member and the cover plate, reducing light obstruction, which is beneficial to increase the amount of light entering the camera device and improve the shooting quality. Among them, the top side of the lifting member can transmit light to serve as the light incident surface of the camera device. After the shooting is completed, the lifting member can be lowered back to the initial position, reducing the overall thickness of the camera device, and allowing more of the lifting member to be located in the internal space of the lifting mechanism, which is beneficial to protecting the lifting member.

[0132] Exemplarily, the housing 300 is used to protect the internal electronic components of the electronic device 1000. The housing 300 may include a cover plate 3001, a frame 3002 and a camera decoration 3003. The cover plate 3001 is located on the side of the display screen 2002 away from the light-transmitting panel 2001, and is stacked with the light-transmitting panel 2001 and the display screen 2002. The frame 3002 is fixed on the cover plate 3001. Exemplarily, the frame 3002 can be fixedly connected to the cover plate 3001 by adhesive. The frame 3002 can also be an integrally formed structure with the cover plate 3001, that is, the frame 3002 and the cover plate 3001 are an integral structure. The frame 3002 is located between the cover plate 3001 and the light-transmitting panel 2001. The light-transmitting panel 2001 can be fixed to the frame 3002 by gluing. The light-transmitting panel 2001, the cover plate 3001 and the frame 3002 enclose the internal accommodation space of the electronic device 1000. The internal accommodation space accommodates the display screen 2002. The cover plate 3001 can be made of metal, plastic, glass and other materials. The cover plate 3001 can be a plate made of a single material, or a plate structure made of multiple materials and spliced ​​by multiple plates. The cover plate 3001 is provided with an installation opening 3001a, and the camera decoration 3003 covers and is fixed at the installation opening 3001a.

[0133] Exemplarily, the camera device 100 is used to take photos / videos. Exemplarily, the camera device 100 is installed in the housing 300, located in the internal accommodation space of the electronic device 1000. Among them, the camera device 100 can be used as a rear camera. For example, the light incident surface of the camera device 100 faces the camera decoration 3003. The camera decoration 3003 is used to protect the camera device 100.

[0134] In some embodiments, the camera decoration 3003 protrudes to the side of the cover plate 3001 away from the light-transmitting panel 2001. In this way, the camera decoration 3003 can increase the installation space 426 of the camera device 100 in the thickness direction of the electronic device 1000. In other embodiments, the camera decoration 3003 can also be flush with the cover plate 3001 or recessed into the internal accommodation space of the electronic device 1000.

[0135] The camera decoration 3003 is provided with a through hole 3004. The through hole 3004 allows the scene light to enter the light incident surface of the camera device 100. In some other embodiments, the electronic device 1000 may not include the camera decoration 3003. In this case, the cover plate 3001 is no longer provided with the mounting opening 3001a, but the through hole 3004 is provided on the cover plate 3001, and the through hole 3004 allows the scene to enter the light incident surface of the camera device 100.

[0136] In other embodiments, the camera device 100 can also be used as a front camera. For example, the light incident surface of the camera device 100 faces the light-transmitting panel 2001. A light path avoidance hole is provided on the display screen 2002. The light path avoidance hole allows the scene light to pass through the light-transmitting panel 2001 and then enter the light incident surface of the camera device 100. In other embodiments, the electronic device 1000 may also include one or more other camera modules 20 (not shown in the figure), which is not strictly limited in the embodiments of the present application.

[0137] In some embodiments, Figure 1B As shown, the electronic device 1000 may also include a circuit board 400 and an image processor 500, the circuit board 400 and the image processor 500 are located in the internal accommodation space of the electronic device 1000, and the image processor 500 is fixed to the circuit board 400 and electrically connected to the circuit board 400. The image processor 500 is communicatively connected with the camera device 100. The image processor 500 is used to obtain image data from the camera device 100 and process the image data. Among them, the communication connection between the camera device 100 and the image processor 500 may include data transmission through electrical connection methods such as wiring, and data transmission may also be achieved through coupling and other methods. It is understandable that the camera device 100 and the image processor 500 may also be communicatively connected through other methods that can achieve data transmission.

[0138] In some embodiments, the electronic device 1000 may further include an analog-to-digital converter (also referred to as an A / D converter, not shown in the figure). The analog-to-digital converter is connected between the camera device 100 and the image processor 500. The analog-to-digital converter is used to convert the signal generated by the camera device 100 into a digital image signal and transmit it to the image processor 500, and then the image processor 500 processes the digital image signal, and finally displays the image or video on the screen 200.

[0139] In some embodiments, the electronic device 1000 may further include a memory (not shown in the figure), which is in communication with the image processor 500. The image processor 500 processes the image digital signal and then transmits the image to the memory, so that when the image needs to be viewed later, the image can be searched from the memory at any time and displayed on the screen 200. In some embodiments, the image processor 500 also compresses the processed image digital signal and stores it in the memory to save memory space.

[0140] In some other embodiments, the electronic device 1000 may not include the screen 200 .

[0141] Understandably, Figure 1A and Figure 1BThe installation position of the camera device 100 of the electronic device 1000 in the illustrated embodiment is merely illustrative, and the present application does not strictly limit the installation position of the camera device 100. In some other embodiments, the camera device 100 may also be installed at other positions of the electronic device 1000, for example, the camera device 100 may be installed at the upper middle or upper right corner of the back of the electronic device 1000. In some other embodiments, the electronic device 1000 may include a terminal body and an auxiliary component that can be rotated, moved or disassembled relative to the terminal body, and the camera device 100 may also be set on the auxiliary component.

[0142] Please refer to Figure 1C to Figure 2B , Figure 1C yes Figure 1A The schematic diagram of the structure of the camera device 100 in the electronic device 1000 is shown as a partial extended structure. Figure 2A yes Figure 1A The structure diagram of the camera device 100 in the electronic device 1000 in some embodiments is shown; Figure 2B yes Figure 2A The structure diagram of the camera device 100 in some usage states is shown.

[0143] In some embodiments, the camera device 100 may include a lifting mechanism 10 and a camera module 20. The lifting mechanism 10 has a lifting member 2 capable of lifting and lowering, the lifting member 2 allows light to pass through, and the camera module 20 may be installed in the internal space of the lifting mechanism 10. The camera module 20 may include a lens 201 and a photosensitive element 202, and the lens 201 and the photosensitive element 202 are arranged at intervals.

[0144] In this embodiment, the lifting member 2 of the lifting mechanism 10 can be raised to the extended position by the through hole 3004 of the camera decorative member 3003, so that the height of the internal space of the lifting mechanism 10 is increased, so as to allow the lens 201 of the camera module 20 or a part of the lens of the lens 201 to move in the direction away from the photosensitive element 202, so as to increase the distance between the lens 201 or a part of the lens of the lens 201 and the photosensitive element 202, increase the focal length of the shooting, and enable the electronic device 1000 to achieve telephoto shooting to improve the shooting effect. In addition, since the lifting member 2 can be extended from the through hole 3004, the light incident surface of the camera device 100 protrudes from the camera decorative member 3003 and the cover plate 3001, which reduces light obstruction, is conducive to increasing the amount of light entering the camera device 100, and improves the shooting quality. Among them, the top side of the lifting member 2 can be light-transmissive, so as to serve as the light incident surface of the camera device 100.

[0145] After shooting is completed, the lifting member 2 can be lowered back to the initial position, reducing the overall thickness of the camera device 100 and allowing more of the lifting member 2 to be located in the internal space of the lifting mechanism 10 , which is beneficial to protecting the lifting member 2 .

[0146] Please refer to FIG. 3A to FIG. 4 , Figure 3A yes Figure 2A The structural diagram of the lifting mechanism 10 in some embodiments is shown. Figure 3B yes Figure 3A The structural schematic diagram of the lifting mechanism 10 in some use states is shown, Figure 4 yes Figure 3A A schematic diagram of a partially exploded structure of the lifting mechanism 10 is shown.

[0147] For the convenience of description in the following text, the lifting mechanism 10 is defined to have a width direction X, a length direction Y and a height direction Z, and the above three directions are perpendicular to each other. Among them, when the lifting mechanism 10 is installed in the electronic device 1000 with the camera device 100, the height direction of the lifting mechanism 10 can be parallel to the thickness direction of the electronic device 1000, that is, perpendicular to the cover plate and the screen of the electronic device 1000. Among them, the light incident side of the lifting mechanism 10 (that is, the side used for light intake) is the top side of the lifting mechanism 10, and the bottom side of the lifting mechanism 10 is opposite to the top side. When the camera device 100 is used as a rear camera, the side of the lifting mechanism 10 close to the cover plate is its top side, and the side close to the screen is its bottom side. In the relevant description below, the lifting mechanism 10 and its components and structures close to the light incident side are "top", and the side away from the light incident side is "bottom". In other embodiments, the coordinate system setting of the lifting mechanism 10 can be flexibly set according to specific actual needs.

[0148] In some embodiments, the lifting mechanism 10 may include a base 1, a lifting member 2, and a driving assembly 3. The lifting member 2 is movably mounted on the base 1. The driving assembly 3 is accommodated in the base 1 and mounted on the base 1. The driving assembly 3 is transmission-connected to the lifting member 2 and is used to drive the lifting member 2 to rise or fall.

[0149] In this embodiment, the driving assembly 3 can drive the lifting member 2 to move relative to the base 1 along the Z direction and protrude from the base 1, and the lifting member 2 rises. The driving assembly 3 can also drive the lifting member 2 to retract relative to the base 1 along the -Z direction, and the lifting member 2 falls.

[0150] in, Figure 3A The lifting mechanism 10 is in a retracted state, and the lifting member 2 is in an initial position relative to the base 1, corresponding to Figure 1A and Figure 2A The camera device 100 is shown in this state. Figure 3BThe lifting mechanism 10 is in the extended state, and the lifting member 2 is in the extended position relative to the base 1, corresponding to Figure 1C and Figure 2B The camera device 100 is shown in this state.

[0151] In some embodiments, the lifting mechanism 10 may further include a connecting rod assembly 4 , a buffer assembly 5 , a waterproof assembly 6 and a decorative component 7 .

[0152] Exemplarily, the connecting rod assembly 4 can be transmission-connected between the lifting member 2 and the driving assembly 3, and the connecting rod assembly 4 is received in the base 1 and movably connected to the base 1. In this embodiment, the connecting rod assembly 4 can drive the lifting member 2 to move with the base 1 as the fulcrum under the drive of the driving assembly 3, so that the lifting member 2 rises or falls, thereby realizing the conversion of the lifting mechanism 10 between the raised state and the retracted state.

[0153] Exemplarily, the buffer assembly 5 is installed on the connecting rod assembly 4, and the buffer assembly 5 is transmission-connected between the driving assembly 3 and the connecting rod assembly 4. In this embodiment, the buffer assembly 5 can provide a buffering effect for the transmission of force between the driving assembly 3 and the connecting rod assembly 4. In this embodiment, when the lifting mechanism 10 is in the extended state, if the lifting member 2 is retracted by external pressure, the buffer assembly 5 can play a force buffering role through deformation, so as to remove part of the force on the lifting member 2, play a role in protecting the lifting member 2, and can reduce the force transmitted to the driving assembly 3, thereby reducing the damage to the driving assembly 3. In addition, after the external pressure on the lifting member 2 is removed, the buffer assembly 5 can also drive the lifting member 2 to rise and return to the extended state through the deformation recovery force.

[0154] Exemplarily, the waterproof component 6 can be arranged around the lifting member 2, and the waterproof component 6 is installed between the inner wall of the base 1 and the lifting member 2. In this embodiment, the waterproof component 6 is used to block the gap between the lifting member 2 and the base 1, thereby playing a waterproof and dustproof role.

[0155] For example, the decorative member 7 is installed on the top side of the base 1. The decorative member 7 surrounds the lifting member 2 and is used to cover the gap between the lifting member 2 and the base 1 to achieve the function of decoration and improving the appearance. When the lifting mechanism 10 is installed on the electronic device 1000, the decorative member 7 can be exposed from the through hole, or can be located under the camera decorative member or the back cover to be hidden.

[0156] It should be noted that the lifting mechanism 10 may also have more or fewer components than those described above, and the embodiments of the present application do not strictly limit this.

[0157] Please refer to Figure 4 and Figure 5A , Figure 5A yes Figure 4The schematic diagram of the structure of the base 1 in the lifting mechanism 10 is shown in another viewing angle.

[0158] In some embodiments, the base 1 may include a top wall 1a, a first side wall 1b, a second side wall 1c, and a third side wall 1d. The first side wall 1b, the second side wall 1c, and the third side wall 1d are located on the same side of the top wall 1a and are fixed to the periphery of the top wall 1a. The first side wall 1b is opposite to the third side wall 1d, and the second side wall 1c is connected between the two opposite ends of the first side wall 1b and the third side wall 1d. The first side wall 1b, the second side wall 1c, the third side wall 1d, and the top wall 1a together enclose an inner space 11 of the base 1. An opening is formed between the ends of the first side wall 1b and the third side wall 1d away from the second side wall 1c, and the opening is connected to the inner space 11. Among them, the top wall 1a is provided with a sink 11a and a receiving hole 12a. The sink 11a, the receiving hole 12a, and the inner space are sequentially connected along the -Z direction.

[0159] Exemplarily, the base 1 may have a drive mounting portion 12. The drive mounting portion 12 is arranged corresponding to the opening, and the drive mounting portion 12 may include a top plate 121 and a side plate 122, and the side plate 122 is fixedly connected to the top plate 121 and bent relative to the top plate 121. The top plate 121 is connected to the top wall 1a and extends from the top wall 1a toward the Y direction. The side plate 122 is installed on the first side wall 1b and extends toward the Y direction.

[0160] The side plate 122 is fixedly connected to the bottom side of the top plate 121, and the size of the side plate 122 in the X direction can be larger than the first side wall 1b, so as to have a larger plate thickness. The drive mounting portion 12 can have a drive mounting hole 123, and the drive mounting hole 123 penetrates from the bottom side of the side plate 122 to the top side of the top plate 121. The boundary line between the top plate 121 and the top wall 1a, and the boundary line between the side plate 122 and the first side wall 1b can be referred to in Figure 4 and Figure 5A In some other embodiments, the boundary line between the top plate 121 and the top wall 1a, and the boundary line between the side plate 122 and the first side wall 1b may also be at other positions, which is not limited in the present application.

[0161] Exemplarily, the base 1 may further include a drive fixing portion 13. The drive fixing portion 13 may include a bump fixedly connected to the bottom side of the top wall 1a. The drive fixing portion 13 may include a drive fixing hole 131, which penetrates the bump along the X direction.

[0162] Please combine Figure 3A , Figure 4 and Figure 5AIn some embodiments, a mounting plate 31 is provided on the bottom side of the driving assembly 3, and the mounting plate 31 of the driving assembly 3 is fitted with the bottom side of the side plate 122, and a fastener passes through the mounting plate 31 and extends into the driving mounting hole 123 of the side plate 122 to fix the mounting plate 31 to the base 1. The driving fixing portion 13 is rotatably connected to the driving shaft 34 of the driving assembly 3 through the driving fixing hole 131, so that the driving shaft 34 can rotate with the driving fixing portion 13 as a fulcrum.

[0163] In this embodiment, the top plate 121 and the side plate 122 are in an inverted "L" structure, so that the top side of the driving assembly 3 can be mounted to the bottom side of the top plate 121, and the side of the driving assembly 3 facing the X direction can be mounted to the side plate 122, thereby increasing the supporting area of ​​the base 1 for the driving assembly 3, which is beneficial to improving the installation stability of the driving assembly 3. Since the size of the side plate 122 in the X direction can be larger than the first side wall 1b, the stability of the side plate 122 in mounting the driving assembly 3 is improved.

[0164] Please refer to Figure 4 and Figure 5A In some embodiments, the base 1 may have a first fixing portion 14 and a second fixing portion 15. The first fixing portion 14 and the second fixing portion 15 are spaced apart.

[0165] Exemplarily, the first fixing portion 14 may include two first convex ribs, which are arranged opposite to each other. The first convex rib may be a part of the first side wall 1b, and is located at the end of the first side wall 1b away from the second side wall 1c; the other first convex rib may be a part of the third side wall 1d, and is located at the end of the first side wall 1b away from the second side wall 1c. The first fixing portion 14 has a first fixing hole 141, and the first fixing hole 141 passes through the two first convex ribs along the X direction. In other embodiments, one first convex rib may be connected to the first side wall 1b, and the other first convex rib may be connected to the third side wall 1d.

[0166] Exemplarily, the first fixing portion 14 may further include two auxiliary ribs, which are fixedly connected to the bottom side of the top wall 1a. One auxiliary rib corresponds to one first rib, and the corresponding auxiliary rib is spaced apart from the first rib, forming a receiving groove 142 therebetween. The first fixing hole 141 also penetrates the two auxiliary ribs along the X direction.

[0167] In some examples, the first fixing portion 14 may further have an auxiliary fixing hole 143, and the auxiliary fixing hole 143 is coaxially arranged with the driving fixing hole 131. In this embodiment, the auxiliary fixing hole 143 penetrates the first convex rib and the auxiliary convex rib close to the third side wall 1d, so that the driving shaft 34 of the driving assembly 3 can pass through the driving fixing hole 131 and the auxiliary fixing hole 143 in sequence, so that the driving fixing portion 13 and the first fixing portion 14 can jointly install the driving shaft 34 of the driving assembly 3, thereby improving the installation stability, which is conducive to improving the stability of the driving assembly 3 driving the connecting rod assembly 4 through the driving shaft 34.

Figure 6B yes Fig. 6A The exploded structural diagram of the connecting rod assembly 4 is shown in FIG. Fig. 7A yes Figure 6B The illustrated diagram is a schematic structural diagram of the long balancing rod 41 in the connecting rod assembly 4 in some embodiments.

[0178] In some embodiments, the connecting rod assembly 4 may include a long balancing rod 41 , a short balancing rod 42 and two connecting rods 43 .

[0179] The long balance pole 41 may include a long support pole 411 and two long poles 412, and the two long poles 412 are arranged opposite to each other. The two long poles 412 are respectively fixed to the two ends of the long support pole 411. The short balance pole 42 is located between the two long poles 412, and the short balance pole 42 includes a short support pole 421 and two short poles 422, and the two short poles 422 are arranged opposite to each other and are respectively connected to the two ends of the short support pole 421. A connecting rod 43 is arranged corresponding to a long pole 412 and a short pole 422, and the connecting rod 43 is rotatably connected between the corresponding long pole 412 and the short pole 422.

The two groups of transmission parts 44 can be symmetrically arranged, and the two groups of transmission parts 44 are connected by the long support rod 411 and the short support rod 421, thereby improving the smoothness of the transmission of the connecting rod assembly 4.

[0181] See also Fig. 7A In some embodiments, the long rod 412 may include a first end 4121, a second end 4122, and a transition portion 4123, and the transition portion 4123 is located between the first end 4121 of the long rod 412 and the second end 4122 of the long rod 412. The long rod 412 may include a first rod 412a, a second rod 412b, and a third rod 412c that are sequentially connected along the Y direction. The first end 4121 and the transition portion 4123 may be located on the first rod 412a, and the second end 4122 may be located on the third rod 412c. The first end 4121 of the long rod 412 may be provided with a first rotation hole 4121a, the second end 4122 of the long rod 412 may be provided with a second rotation hole 4122a, and the transition portion 4123 may be provided with a third rotation hole 4123a.

[0182] Exemplarily, the bottom side of the long rod 412 is a plane. Along the Z direction, the height of the first rod 412a is greater than the size of the second rod 412b, and the height of the second rod 412b is greater than the size of the third rod 412c. In this embodiment, the height of the first rod 412a is high, so that the adapter 4123 can provide more installation space in the Z direction. In other embodiments, the adapter 4123 can also be located at the second rod 412b or the connection between the first rod 412a and the second rod 412b.

[0183] The first rotating hole 4121a and the third rotating hole 4123a are farther from the bottom side of the long rod 412 than the second rotating hole 4122a. At this time, in the Z direction, the first rotating hole 4121a and the third rotating hole 4123a are higher than the second rotating hole 4122a.

[0184] Among them, from the first end 4121 of the long rod 412 to the second end 4122 of the long rod 412, the height of the third rod 412c in the Z direction gradually decreases, so that the top side surface of the third rod 412c is an inclined surface, thereby reducing the size of the second end 4122 of the long rod 412 in the Z direction.

[0185] The long support rod 411 can be fixed between the first rods 412 a of the two long rods 412 , so that the long support rod 411 is fixed at the position where the structural strength of the long rods 412 is the strongest, thereby improving the overall structural strength of the long balance rod 41 .

[0186] Among them, along the Z direction, the height of the long support rod 411 is smaller than the size of the first rod 412a, and the long support rod 411 can be fixed to the part of the first rod 412a close to the bottom side, so that there is a receiving space between the two first rods 412a, which can be used to install other components, thereby improving space utilization.

[0187] See also Figure 7B , Figure 7B yes Figure 6B The schematic diagram of the structure of the short balancing rod 42 in the connecting rod assembly 4 is shown in another perspective.

[0198] See also Figure 6B In some embodiments, the connecting rod 43 may include a first end 431 and a second end 432. The first end 431 of the connecting rod 43 may be provided with a transfer hole 4311. The second end 432 of the connecting rod 43 may be provided with a transfer post 4321.

[0199] Please refer to FIG. 6A to FIG. 7B In some embodiments, the short balancing rod 42 may be disposed between the two long rods 412. The connecting rod 43 is rotatably connected between the long rod 412 and the short rod 422. The first end 431 of the connecting rod 43 is rotatably connected to the adapter portion 4123 of the long rod 412, and the second end 432 of the connecting rod 43 is rotatably connected to the third rotating portion 4224 of the short rod 422.

[0200] In this embodiment, the short balancing rod 42 can drive the short rod 422 to move together after being subjected to force, and drive the long rod 412 to move together through the connecting rod 43, so that the long rod 412 and the short rod 422 move synchronously.

[0201] Exemplarily, the transfer column 4321 of the connecting rod 43 can pass through the third rotation hole 4224a of the third rotating portion 4224 of the short rod 422, so that the second end 432 of the connecting rod 43 is rotatably connected to the short rod 422. The transfer hole 4311 of the connecting rod 43 is coaxially arranged with the third rotation hole 4123a of the transfer portion 4123 of the long rod 412. Among them, the transmission member 44 can also include a plurality of rotating shafts, and the plurality of rotating shafts include a rotating shaft that passes through the third rotation hole 4123a and extends into the transfer hole 4311, so that the first end 431 of the connecting rod 43 is rotatably connected to the long rod 412. In some other embodiments, the third rotation shaft 443 can be fixedly connected to the first end 431 of the connecting rod 43, and the transfer column 4321 can be detachably connected to the second end 432 of the connecting rod 43.

[0202] The transmission member 44 may further include a first rotating shaft 441, a second rotating shaft 442, a third rotating shaft 443, a first rotating shaft 444 and a second rotating shaft 445. The first rotating shaft 441 may pass through the first rotating hole 4121a. The second rotating shaft 442 may pass through the second rotating hole 4122a.

[0203] The area where the end surface of the rod body 4221 of the short rod 422 and the first rotating portion 4222 are spaced apart can accommodate the connecting rod 43 to provide space for the connecting rod 43 .

[0204] Please refer to Figure 5B , Fig. 8A and Figure 8B , Fig. 8A yes Figure 3A The schematic diagram of the connection structure between the connecting rod assembly 4 and the lifting member 2 in the lifting mechanism 10 shown in FIG. Figure 8B yes Fig. 8A A schematic top view of the connecting rod assembly 4 and the lifting member 2 is shown.

[0205] In some embodiments, the lifting member 2 may be located between the two long rods 412 , and the short balancing rod 42 may be located between the lifting member 2 and the long supporting rod 411 .

[0206] Exemplarily, the first end 25 of the lifting member 2 is connected between the second ends 4122 of the two long rods 412 , and the second end 26 of the lifting member 2 is connected between the two short rods 422 .

[0207] Among them, a matching hole 2511 of the lifting member 2 is provided corresponding to the second end 4122 and a second rotating shaft 442 of a long rod 412 in a group of transmission members 44, and a sliding groove 2611 of the lifting member 2 is provided corresponding to the second rotating portion 4223 and a second rotating shaft 445 of a short rod 422 in a group of transmission members 44. The second rotating shaft 442 passes through the second rotating hole 4122a of the long rod 412 and extends into the matching hole 2511 of the lifting member 2, so that the second end 4122 of the long rod 412 is rotatably connected to the first end 25 of the lifting member 2. The second rotating shaft 445 passes through the second rotating hole 4223a of the second rotating portion 4223 of the short rod 422 and is at least partially located in the sliding groove 2611, so that the second rotating shaft 445 is slidably connected to the second end 26 of the lifting member 2. In this embodiment, the connecting rod assembly 4 can move under the drive of the driving assembly and drive the first end 25 and the second end 26 of the lifting member 2 to move.

[0208] Exemplarily, the opening of the first avoidance groove 212 of the lifting member 2 faces the long rod 412, and the first avoidance groove 212 can accommodate part of the long rod 412 in the retracted state. In this embodiment, in the retracted state, since the lifting member 2 can avoid the long rod 412 through the first avoidance groove 212, the arrangement of the lifting member 2 and the connecting rod assembly 4 is more compact, and the size of the lifting mechanism 10 in the Z direction can be reduced, which is conducive to realizing a lightweight design of the electronic device 1000.

[0209] Illustratively, the accommodating space 4225 formed between the two second rotating portions 4223 of the short balancing rod 42 can accommodate at least a portion of the second end 26 of the lifting member 2, so that the rotational connection between the short balancing rod 42 and the second end 26 of the lifting member 2 is more stable.

[0210] Please refer to FIG. 8B to FIG. 9B , Fig. 9A yes Fig. 8A The schematic diagram of partial structural decomposition of a group of transmission members 44 and lifting member 2 in the connecting rod assembly 4 is shown. Fig. 9B yes Fig. 8A The diagram is a partial structural exploded view of another group of transmission components 44 and the lifting component 2 in the connecting rod assembly 4.

[0211] In some embodiments, the two sets of transmission members 44 can be symmetrically connected to the first side 27 of the lifting member 2 and the second side 28 of the lifting member 2. The lifting member 2 has a symmetry plane passing through the axis and parallel to the XY plane (see Figure 8B M), the two groups of transmission parts 44 are symmetrical about the symmetry plane M.

[0212] In this embodiment, the two long rods 412 are fixedly connected by the long support rod 411, so that the two second rotation shafts 442 rotatably connected to the two sides of the first end 25 of the lifting member 2 are located on the long balance rod 41, so that the two second rotation shafts 442 can move synchronously, and the lifting and lowering balance of the lifting member 2 on the first side 27 and the second side 28 of the first end 25 is achieved, thereby improving the lifting and lowering smoothness of the lifting member 2. The two short rods 422 are fixedly connected by the short support rod 421, so that the two second rotation shafts 445 slidably connected to the two sides of the second end 26 of the lifting member 2 are located on the short balance rod 42, so that the two second rotation shafts 445 can move synchronously, and the lifting and lowering balance of the lifting member 2 on the first side 27 and the second side 28 of the second end is achieved.

[0213] In this embodiment, since the connecting rod 43 in each group of transmission members 44 is correspondingly connected by rotation with a long rod 412 and a short rod 422, the long rod 412 and the short rod 422 in each group of transmission members 44 can move synchronously. Therefore, on the first side 27 of the lifting member 2, the second rotating shaft 442 and the second rotating shaft 445 can move synchronously to achieve the lifting balance of the first end 25 and the second end 26 of the lifting member 2 on the first side 27. On the second side 28 of the lifting member 2, the second rotating shaft 442 and the second rotating shaft 445 can move synchronously to achieve the lifting balance of the first end 25 and the second end 26 of the lifting member 2 on the second side 28.

[0214] Please refer to Figure 5A , Fig. 9A and Fig. 10A , Fig. 10A yes Figure 3A The side view of the lifting member 2 is shown. Fig. 10A The midpoint dashed line represents base 1.

[0215] In some embodiments, the first end 4121 of the long rod 412 is rotatably connected to the first fixing portion 14 of the base 1 , and the first rotating portion 4222 of the short rod 422 is rotatably connected to the second fixing portion 15 of the base 1 .

[0216] Exemplarily, the first rotating shaft 441 passes through the first rotating hole 4121a of the long rod 412 and extends into the first fixing hole 141 of the first fixing portion 14. The first rotating shaft 444 passes through the first rotating hole 4222a of the first rotating portion 4222 of the short rod 422 and extends into the second fixing hole 151 of the second fixing portion 15.

[0217] In this embodiment, the long rod 412 and the short rod 422 are connected to the base 1 by rotation, so that the long rod 412 and the short rod 422 can simultaneously drive the lifting member 2 to rise and fall relative to the base 1 along the Z direction. Therefore, when the short rod 422 is subjected to force, the short rod 422 rotates with the axis of the first rotating shaft 444 as the rotation center, and drives the second end 26 of the lifting member 2 to move through the second rotating part 4223, so that the second end 26 of the lifting member 2 is displaced in the Z direction. At the same time, the short rod 422 also drives the long rod 412 to rotate with the axis of the first rotating shaft 441 as the rotation center through the third rotating part 4224, so that the second end 4122 of the long rod 412 drives the first end 25 of the lifting member 2 to move, so that the first end 25 of the lifting member 2 is displaced in the Z direction, thereby realizing the simultaneous displacement of the first end 25 of the lifting member 2 and the second end 26 of the lifting member 2 in the Z direction, thereby realizing the conversion of the extended state and the retracted state of the lifting mechanism 10.

[0218] Among them, since the height of the first rod 412a along the Z direction is the largest, and the first end 4121 and the adapter 4123 of the long rod 412 are both located on the first rod 412a, the first rod 412a can provide higher structural strength to support the first end 4121 of the long rod 412 to be rotatably connected to the base 1, and to support the adapter 4123 to be rotatably connected to the connecting rod 43, thereby improving the stability of the relative rotation between the long rod 412 and the base 1 and the connecting rod 43.

[0219] Among them, the first end 4121 of the long rod 412 is arranged in the receiving groove 142 of the first fixing part 14 of the base 1, and the axis of the first rotating hole 4121a of the long rod 412 coincides with the axis of the first fixing hole 141 of the first fixing part 14, thereby improving the stability of the rotational connection between the long rod 412 and the base 1.

[0220] Among them, the second fixed part 15 of the base 1 is arranged in the limiting groove 424 between the limiting block 423 of the short balance rod 42 and the first rotating part 4222 of the short rod 422, and the axis of the second fixing hole 151 of the second fixed part 15 coincides with the axis of the first rotating hole 4222a of the first rotating part 4222, thereby improving the stability of the rotational connection between the short rod 422 and the base 1.

[0221] Please refer to Fig. 8A , Fig. 9B and Fig. 10B , Fig. 10B yes Fig. 10A The schematic diagram of the lifting mechanism 10 is shown. Fig. 10B The dashed line with an arrow in the middle indicates the direction of rotation.

[0222] For the sake of convenience in the following description, the hollow circle in the mechanism diagram represents the rotatable parts in the lifting mechanism 10, the straight line represents the parts in the lifting mechanism 10 that can rotate with the hollow circle as the rotation center, the two straight lines passing through the solid sector are fixedly connected, the triangle with a slope on the bottom side represents a fixed point, and there is no motion interference between the intersecting straight lines.

[0223] In some embodiments, in the YZ plane, the portion between the first fixing portion 14 and the second fixing portion 15 of the base 1 can be regarded as the fixing rod 16 of the base 1. The long rod 412 may include a first section 4124 and a second section 4125 that are fixedly connected, the first section 4124 of the long rod 412 is the center line of the first rotating hole 4121a and the third rotating hole 4123a, and the second section 4125 of the long rod 412 is the center line of the third rotating hole 4123a and the second rotating hole 4122a of the long rod 412. The short rod 422 may include a first section 4226 and a second section 4227 that are fixedly connected, the first section 4226 of the short rod 422 is the center line of the first rotating hole 4222a of the first rotating portion 4222 and the third rotating hole 4224a of the third rotating portion 4224, and the second section 4227 of the short rod 422 is the center line of the third rotating hole 4224a and the second rotating hole 4223a of the second rotating portion 4223.

[0224] In this embodiment, the fixed rod 16, the first section 4124 of the long rod 412, the connecting rod 43 and the first section 4226 of the short rod 422 are connected end to end in sequence to form a four-bar linkage. The second section 4125 of the long rod 412 and the second section 4227 of the short rod 422 can be lifted and lowered together with the movement of the four-bar linkage. The four-bar linkage improves the smoothness of the extension and retraction of the lifting mechanism 10.

[0225] Among them, the second section 4125 of the long rod 412, one end of which is away from the first section 4124 of the long rod 412, is rotatably connected to the matching hole 2511 of the first end 25 of the lifting member 2, and the second section 4227 of the short rod 422, one end of which is away from the first section 4226 of the short rod 422, is slidably connected to the sliding groove 2611 of the second end 26 of the lifting member 2. Therefore, when the four-bar linkage moves, the second section 4125 of the long rod 412 and the second section 4227 of the short rod 422 can be lifted and lowered together with the movement of the four-bar linkage, thereby driving the lifting member 2 to be lifted and lowered together.

[0226] In this embodiment, in the retracted state, from the perspective of the X direction, when the first section 4226 of the short rod 422 is subjected to the clockwise force driving force F1, the first section 4226 of the short rod 422 can rotate in the clockwise direction, and drive the second section 4227 of the short rod 422 to rotate in the clockwise direction, thereby driving the second end 26 of the lifting member 2 to rotate in the clockwise direction, so as to achieve the displacement of the second end 26 of the lifting member 2 in the Z direction. At the same time, the short rod 422 also drives the first section 4124 of the long rod 412 to rotate in the clockwise direction through the connecting rod 43, so that the first section 4124 of the long rod 412 drives the second section 4125 of the long rod 412 to rotate in the clockwise direction, thereby driving the first end 25 of the lifting member 2 to rotate in the clockwise direction, so as to achieve the displacement of the first end 25 of the lifting member 2 in the Z direction, thereby achieving the overall rise of the lifting member 2, so that the lifting member 2 rises to the position as shown in FIG. Fig.11 , Fig. 12A and Fig. 12B Status shown.

Fig. 12A The midpoint dashed line shows the base 1. Fig. 12B The dashed line with an arrow in the middle indicates the direction of rotation.

[0228] In some embodiments, in the extended state, from the perspective of the X direction, when the first section 4226 of the short rod 422 is subjected to the counterclockwise retraction force F2, the first section 4226 of the short rod 422 can rotate in the counterclockwise direction, and drive the second section 4227 of the short rod 422 to rotate in the counterclockwise direction, thereby driving the second end 26 of the lifting member 2 to rotate in the counterclockwise direction, so as to achieve the displacement of the second end 26 of the lifting member 2 in the -Z direction. At the same time, the short rod 422 also drives the first section 4124 of the long rod 412 to rotate in the counterclockwise direction through the connecting rod 43, so that the first section 4124 of the long rod 412 drives the second section 4125 of the long rod 412 to rotate in the counterclockwise direction, thereby driving the first end 25 of the lifting member 2 to rotate in the counterclockwise direction, so as to achieve the displacement of the first end 25 of the lifting member 2 in the -Z direction, thereby achieving the overall descent of the lifting member 2, so that the lifting member 2 descends to a position such as Fig. 8A , Fig. 10A and Fig. 10B Status shown.

[0229] Among them, the first section 4226 of the short rod 422 and the second section 4227 of the short rod 422 are arranged at an angle, which is conducive to the short rod 422 matching the movement requirements and space requirements of the four-bar linkage mechanism.

[0230] See also Figure 8B , Fig. 10B and Fig. 12B In some embodiments, the two groups of transmission members 44 located on both sides of the lifting member 2 can form two groups of four-bar linkage mechanisms with the base 1.

[0231] In this embodiment, since the two groups of transmission members 44 are connected by the long support rod 411 and the short support rod 421, the two groups of four-bar linkages can move simultaneously. Driven by the two short rods 422, the first side 27 and the second side 28 of the lifting member 2 can be lifted and lowered simultaneously, so that the second end 26 of the lifting member 2 can be lifted and lowered smoothly. Driven by the two long rods 412, the first side 27 and the second side 28 of the first end 25 of the lifting member 2 can be lifted and lowered simultaneously, so that the first end 25 of the lifting member 2 can be lifted and lowered smoothly. Driven by the two short rods 422 and the two long rods 412, the first end 25 and the second end 26 of the lifting member 2 can be lifted and lowered simultaneously along the Z direction, so that the overall lifting of the lifting member 2 can be lifted and lowered smoothly. Therefore, by driving the two groups of four-bar linkages at the same time, the two sides of the lifting member 2 can be driven to lift and lower at the same time, thereby improving the lifting stability of the lifting member 2.

[0232] Please refer to Fig. 8A and Fig.11 In some embodiments, the driving assembly 3 can apply the driving force to the short support rod 421 (see Fig. 8A F1 in the figure), the short support rod 421 is driven by the driving force F1 to drive the short rod 422 and the long rod 412, so that the short rod 422 and the long rod 412 jointly drive the lifting member 2 to rise.

[0233] The point of action of the driving force F1 on the short support rod 421 is close to the bottom side of the short support rod 421, so that the force arm of the driving force F1 is longer, thereby improving the driving efficiency.

[0234] In some embodiments, the drive assembly 3 can apply a retraction force to the short support rod 421 (see Fig.11 F2 in the figure), the short support rod 421 is pulled by the retraction force F2 to drive the short rod 422 and the long rod 412, so that the short rod 422 and the long rod 412 jointly drive the lifting member 2 to descend.

[0235] Exemplarily, the point of action on the short support rod 421 when driving the lifting member 2 to retract is the same as the point of action on the short support rod 421 when driving the connecting rod assembly 4 to drive the lifting member 2 to extend, so that the driving of the connecting rod assembly 4 by the driving assembly 3 is continuous and can maintain the stable movement of the lifting member 2 to prevent the lifting member 2 from deflecting.

[0236] In some other embodiments, the force of the driving component 3 to drive the lifting member 2 to extend and retract can act on the short rod 422, or the long rod 412, or the short support rod 421, etc. In the embodiment of the present application, the driving force of the driving component 3 is only used to illustrate the action on the short support rod 421, and the object of the driving force of the driving component 3 is not limited.

[0237] In some other embodiments, in the extended state, when the top side of the lifting member 2 is subjected to a force toward the −Z direction, the lifting member 2 can drive the connecting rod assembly 4 to rotate, so as to realize the descent of the lifting member 2 .

[0238] Please refer to Figure 5B , Fig. 9A and Fig.13 , Fig.13 yes Fig. 10A The schematic diagram of the lifting mechanism 10 during the lifting process is shown.

[0239] In some embodiments, the axis of the lifting member 2 when it is in the initial position (see Fig. 10A O in the extended position (see Fig. 12A The axis of the lifting member 2 when in the initial position is parallel to the Z direction.

[0240] In this embodiment, the axis of the lifting member 2 coincides with the initial position and the extended position, so that the relative position of the lifting member 2 and the base 1 in the initial position and the extended position is not offset in the XY plane, and the optical axis of the lifting member 2 can be kept without offset, thereby ensuring the lighting quality of the camera module located in the inner space of the lifting member 2, thereby ensuring the camera quality of the camera device 100.

[0241] Exemplarily, the line connecting the second end 4122 of the long rod 412 at the extended position and the retracted position is parallel to the Z direction. In other words, when in the retracted state, the line connecting the first end 25 of the lifting member 2 at the extended position and the retracted position is parallel to the Z direction. In this embodiment, the lifting member 2 is extended from the initial position to the extended position, and the lifting member 2 does not rotate around the axis of the lifting member 2, so that the lifting member 2 moves stably in the transition between the extended state and the retracted state.

[0242] In some embodiments, the size of the sliding groove 2611 of the second end 26 of the lifting member 2 in the Y direction is greater than the outer diameter of the second rotating shaft 445. In this embodiment, the second rotating shaft 445 can move in the groove along the ±Y direction.

[0243] In the process of the lifting member 2 switching between the initial position and the extended position, the long rod 412 rotates with the axis of the first rotating shaft 441 as the rotation center, so that the movement path of the second end 4122 of the long rod 412 and the second rotating shaft 442 is an arc. In other words, the movement path of the first end 25 of the lifting member 2 during the rising and falling process is an arc, and the arc has the axis of the first rotating shaft 441 as the center. Therefore, the first end 25 of the lifting member 2 has a movement distance in the Y direction during the rising and falling process, thereby driving the second end 26 of the lifting member 2 to have a movement distance in the Y direction.

[0244] In the process of the lifting member 2 switching between the initial position and the extended position, the short rod 422 rotates with the axis of the first rotating shaft 444 as the rotation center, so that the movement path of the second rotating portion 4223 of the short rod 422 and the second rotating shaft 445 is an arc. In other words, the movement path of the second end 26 of the lifting member 2 during the rising and falling process is an arc, and the arc has the axis of the first rotating shaft 444 as the center. Therefore, the second end 26 of the lifting member 2 has a movement distance in the Y direction during the rising and falling process.

[0245] The movement paths of the second end 4122 of the long rod 412 and the second rotating shaft 442 are inconsistent with the movement paths of the second rotating portion 4223 of the short rod 422 and the second rotating shaft 445 in the Y direction, so that during the rising and falling processes, the movement deviations of the first end 25 and the second end 26 of the lifting member 2 in the Y direction are not synchronized. In this embodiment, by setting the size of the sliding groove 2611 in the Y direction to be larger than the outer diameter of the second rotating shaft 445, the second rotating shaft 445 can move in the sliding groove 2611 along the Y direction during the lifting process of the lifting member 2, thereby eliminating the movement deviations of the first end 25 and the second end 26 of the lifting member 2 in the Y direction during the lifting process, and improving the smoothness of the lifting movement of the lifting member 2.

[0246] Exemplarily, the size difference between the size of the sliding groove 2611 in the Y direction and the outer diameter of the second rotating shaft 445 is in the range of 0 mm to 0.08 mm. For example, the size difference may be, but is not limited to, 0.01 mm, or 0.03 mm, or 0.05 mm, or 0.07 mm, or 0.08 mm, or other values ​​in the range of 0.01 mm to 0.08 mm.

[0247] The sliding groove 2611 may be a linear groove, and the extending direction of the sliding groove 2611 is perpendicular to the axis of the lifting member 2, which is conducive to the consistency of the height of the first end 25 and the second end 26 of the lifting member 2, so that the lifting strokes of the first end 25 and the second end 26 of the lifting member 2 are consistent, thereby improving the stability of the lifting member 2. In some other embodiments, the sliding groove 2611 may also be an arc groove or a spline curve groove, which is specifically designed according to the movement path of the second rotating shaft 445 during the lifting process of the lifting member 2, as long as the lifting strokes of the first end 25 and the second end 26 of the lifting member 2 can be consistent.

[0248] In this embodiment, since the lifting member 2 can have a second avoidance groove 221, the second avoidance groove 221 is used to avoid other structural parts, such as decorative parts, during the lifting process of the lifting member 2, so as to avoid collision, damage or movement deviation in the Y direction that affects the lifting accuracy, so as to avoid collision of the lifting member 2 during the lifting process.

[0249] In this embodiment, in the retracted state, the first rotating hole 4121a of the long rod 412 is located on one side of the second rotating hole 4122a in the Z direction, and the bottom side of the long rod 412 is a plane and parallel to the XY plane. Since the axis of the first rotating hole 4121a is the rotation center of the long rod 412, and in the Z direction, the height of the first rod 412a of the long rod 412 is greater than the height of the third rod 412c, by setting the first rotating hole 4121a higher than the second rotating hole 412a, the connecting rod assembly 4 can drive the lifting member 2 to rise in the Z direction, and the third rod 412c can move in the Z direction to utilize the size of the first rod 412a in the Z direction, so that when the movement stroke of the lifting member 2 remains unchanged, the size space occupied by the lifting mechanism 10 in the Z direction can be reduced, which is conducive to the lightweight design of the lifting mechanism 10.

[0250] In this embodiment, since the top side surface of the third rod 412c of the long rod 412 is an inclined surface, the size of the second end 4122 of the long rod 412 in the Z direction is reduced, so that the weight of the long rod 412 is light, thereby reducing the power consumption required to drive the long rod 412 to move and improving the movement flexibility of the long rod 412.

[0251] In some other embodiments, the matching hole 2511 of the first end 25 of the lifting member 2 may be changed into a slot structure, and the sliding slot 2611 of the second end 26 of the lifting member 2 may be changed into a hole structure. The second end 4122 of the long rod 412 is slidably connected to the second end 26 of the lifting member 2, and the second rotating portion 4223 of the short rod 422 is rotatably connected to the first end 25 of the lifting member 2. In this embodiment, the slot structure of the first end 25 of the lifting member 2 eliminates the movement deviation of the first end 25 and the second end of the lifting member 2 in the Y direction during the lifting process, thereby improving the smoothness of the lifting movement of the lifting member 2.

[0252] Please refer to FIG. 14A to FIG. 14C , Fig.14A yes Figure 4 The schematic diagram of the structure of the buffer assembly 5 in the lifting mechanism 10 in some embodiments is shown. Fig. 14B yes Fig.14A The schematic diagram of the exploded structure of the buffer assembly 5 is shown. Fig. 14C yes Fig.14A The structure diagram of the buffer assembly 5 shown is from another perspective.

[0253] In some embodiments, the buffer assembly 5 is rotatably connected between the short support rod 421 and the driving assembly. The buffer assembly 5 may include a buffer rod 51 , a torsion spring 52 and a buffer shaft 53 .

[0254] Exemplarily, the buffer rod 51 has a receiving groove 511, and the buffer rod 51 also has a buffer rotation hole 512, which penetrates the buffer rod 51 along the extension direction of the buffer rod 51 and is connected to the receiving groove 511. The buffer rod 51 is also provided with a transmission protrusion 513, which is arranged opposite to the receiving groove 511. The buffer rod 51 also has a transmission hole 514, which penetrates the transmission protrusion 513 along the extension direction of the buffer rod 51. The buffer rod 51 also has a receiving groove 515, which penetrates the transmission protrusion 513 and is arranged opposite to the receiving groove 511, and the receiving groove 515 is connected to the transmission hole 514. The buffer rod 51 may also have a baffle 516, which is connected to the bottom wall of the receiving groove 511 and extends in a direction away from the receiving groove 511. In this embodiment, the baffle 516 extends from the bottom wall of the receiving groove 511 toward the -Z direction. Two support blocks 517 are respectively protruded from both ends of the buffer rod 51 .

[0255] The buffer rod 51 is installed in the installation space 426 of the short balance rod 42, and the receiving groove 511 is arranged toward the short support rod 421. The buffer rotating hole 512 is coaxially arranged with the fourth rotating hole 4231 of the limiting block 423 of the short balance rod 42. The supporting block 517 abuts against the limiting rib 425 of the short balance rod 42. The torsion spring 52 is installed in the receiving groove 511, and the torsion spring 52 is located between the bottom wall of the receiving groove 511 and the short support rod 421. The buffer rotating shaft 53 passes through the fourth rotating hole 4231, the spring body 52a of the torsion spring 52 and the buffer rotating hole 512.

[0256] In some embodiments, in the retracted state, one pin 52b of the torsion spring 52 elastically abuts against the short support rod 421, and the other pin 52b elastically abuts against the bottom wall of the receiving groove 511. The force of the torsion spring 52 acting on the short support rod 421 and the bottom wall of the receiving groove 511 causes the support block 517 of the buffer rod 51 to abut against the limiting rib 425 of the short balance rod 42.

[0257] In this embodiment, the torsion spring 52 is in a compressed state. The force of the torsion spring 52 acting on the short support rod 421 is opposite to the force direction of the support block 517 of the buffer rod 51 pressing against the limiting rib 425 of the short balance rod 42. The force of the torsion spring 52 acting on the bottom wall of the receiving groove 511 of the buffer rod 51 is opposite to the force direction of the limiting rib 425 of the short balance rod 42 pressing against the support block 517 of the buffer rod 51. This balances the force between the buffer rod 51 and the short balance rod 42, and they can remain relatively still when not affected by external forces. This is beneficial to improving the stability of the connection between the buffer rod 51 and the short support rod 421, thereby improving the transmission stability.

[0258] In this embodiment, since the torsion spring 52 is always in a compressed state, the torsion spring 52 can maintain a certain rigidity, and when the buffer rod 51 is subjected to force to further slowly compress the torsion spring 52, the torsion spring 52 can quickly return to the initial state to drive the short balance rod 42. Therefore, when the buffer rod 51 is subjected to force to slowly compress the torsion spring 52, the buffer assembly 5 and the short balance rod 42 can be regarded as a whole and move synchronously when subjected to force.

[0259] Exemplarily, the buffer assembly 5 can drive the short balance bar 42 to move under the drive of an external force. In this embodiment, the buffer assembly 5 can drive the short balance bar 42 to move under the drive of the drive assembly 3, thereby achieving the lifting of the lifting member 2.

[0260] In the process of driving the lifting member to rise, the buffer rod 51 is subjected to force and rotates with the buffer shaft 53 as the rotation fulcrum toward the direction of the short balance rod 42. When the buffer rod 51 is subjected to force and rotates slowly, the buffer assembly 5 and the short balance rod 42 can rotate synchronously, thereby cooperating with the long balance rod 41 to drive the lifting member 2 to rise. When the buffer rod 51 is subjected to force and rotates faster, the buffer rod 51 is subjected to force and rotates with the buffer shaft 53 as the rotation fulcrum toward the direction of the short balance rod 42, and the distance between the bottom wall of the receiving groove 511 and the short support rod 421 is reduced, thereby driving the two pins 52b of the torsion spring 52 to approach each other, so that the torsion spring 52 undergoes further compression deformation, and the deformation recovery force generated by the torsion spring 52 recovering the deformation will act on the short support rod 421, and drive the short support rod 421 to rotate in the direction away from the buffer assembly 5, thereby causing the short balance rod 42 to rotate in the direction away from the buffer assembly 5, so as to cooperate with the long balance rod 41 to drive the lifting member 2 to rise.

[0261] Among them, the baffle 516 can be set corresponding to the pin 52b of the torsion spring 52 close to the bottom wall of the receiving groove 511, thereby increasing the contact surface between the buffer rod 51 and the pin 52b of the torsion spring 52 when the buffer rod 51 rotates toward the short support rod 421, which is beneficial to driving the torsion spring 52 to drive the short support rod 421, thereby improving the force transmission efficiency.

[0262] In the process of the lifting member 2 descending, the driving assembly drives the buffer rod 51 to rotate away from the short support rod 421, and the buffer rod 51 can be supported by the limiting rib 425 through the support block 517, and drives the short support rod 421 to rotate together, thereby driving the lifting member to descend. In the process of the lifting member descending, there is no need to use the deformation and deformation recovery of the torsion spring 52 to transmit force, so that the force transmission speed during the descent process is fast, which is conducive to the rapid descent of the lifting member. In addition, there is no need to stretch the two pins 52b of the torsion spring 52, which can reduce the force fatigue of the torsion spring 52, thereby increasing the service life of the torsion spring 52.

[0263] In some other embodiments, in the retracted state, the torsion spring 52 is located between the short support rod 421 and the bottom wall of the receiving groove 511, and the torsion spring 52 has no elastic deformation. In other words, there is a gap between the torsion spring 52 and at least one of the short support rod 421 and the bottom wall of the receiving groove 511, so that the torsion spring 52 only needs to be deformed during the extension process of the lifting member 2, reducing the number of deformation times of the torsion spring 52, thereby increasing the life of the torsion spring 52.

[0264] Please refer to Fig. 14B , Fig.15A and Fig. 15B , Fig.15A yes Figure 3A The schematic diagram of the structure of the driving assembly 3 and the connecting rod assembly 4 in the lifting mechanism 10 in some embodiments is shown. Fig. 15B yes Fig.15A The schematic diagram of the lifting mechanism 10 is shown in FIG. Fig. 15B The wavy line in FIG. 5 represents the torsion spring 52 .

[0265] In some embodiments, the driving assembly 3 may include a motor 32 , a reduction gearbox 33 , a driving shaft 34 , a crank 35 , and a transmission rod 36 .

[0266] Exemplarily, the motor 32 can be connected to the drive shaft 34 through a reduction box 33. In this embodiment, the motor 32 and the drive shaft 34 are connected through the reduction box 33, so that the high-speed rotation of the motor 32 can be reduced to a suitable rotation speed, and output by the drive shaft 34, thereby improving the speed control of the drive shaft 34, thereby improving the lifting stability of the lifting member 2. In some other embodiments, the motor 32 can be directly connected to the crank 35 and used to drive the crank 35 to rotate, thereby improving the transmission efficiency.

[0267] Exemplarily, the crank 35 may include a first end 351 and a second end 352. The first end 351 of the crank 35 has a first through hole, the second end 352 of the crank 35 has a transmission groove 3521 and a second through hole, and the second through hole is connected to the transmission groove 3521. The transmission rod 36 may include a first end 361 and a second end 362, the first end 361 of the transmission rod 36 has a third through hole, and the second end 362 of the transmission rod 36 has a fourth through hole.

[0268] The driving shaft 34 can pass through the first through hole and be fixedly connected to the first end 351 of the crank 35. The first end 361 of the transmission rod 36 can be accommodated in the transmission groove 3521, and the third through hole of the transmission rod 36 and the second through hole of the crank 35 are coaxially arranged. By passing the rotating shaft through the second through hole and the third through hole, the second end 352 of the crank 35 and the first end 361 of the transmission rod 36 can be rotatably connected. The second end 362 of the transmission rod 36 can be accommodated in the receiving groove 515, and the fourth through hole and the transmission hole 514 of the buffer rod 51 are coaxially arranged. By passing the rotating shaft through the fourth through hole and the transmission hole 514, the second end 362 of the transmission rod 36 and the buffer rod 51 can be rotatably connected.

[0269] In this embodiment, the motor 32 can rotate through the driving rod crank 35 to drive the transmission rod 36 to drive the buffer rod 51 to rotate, thereby driving the lifting member 2 to move up and down, so that the lifting mechanism 10 switches between the retracted state and the extended state.

[0270] Among them, since the axis of the buffer rod 51 coincides with the axis of the first rotating hole 4222a of the first rotating portion 4222 of the short rod 422, the axis of the buffer rotating shaft 53 of the buffer assembly 5 coincides with the axis of the first rotating shaft 444 of the transmission member. Therefore, when the short rod 422 rotates with the axis of the first rotating shaft 444 as the rotation center, the buffer rod 51 rotates with the axis of the buffer rotating shaft 53 as the rotation center, which can be regarded as the buffer rod 51 rotating with the axis of the first rotating shaft 444 as the rotation center.

[0271] The first end 351 of the crank 35 is rotatably connected to the drive shaft 34, the second end 352 of the crank 35 is rotatably connected to the first end 361 of the transmission rod 36, and the second end 362 of the transmission rod 36 is rotatably connected to the buffer rod 51. The buffer rod 51 is elastically connected to the short support rod 421 through the torsion spring 52, which can be regarded as an elastic connection between the buffer rod 51 and the first section 4226 of the short rod 422. The first section 4226 of the short rod 422 is rotatably connected to the second fixing portion 15 of the base 1, and the second section 4227 of the short rod 422 is slidably connected to the sliding groove 2611 of the second end 26 of the lifting member 2. The first section 4124 of the long rod 412 is rotatably connected to the first fixing portion 14 of the base 1, and the second section 4125 of the long rod 412 is rotatably connected to the matching hole of the first end 25 of the lifting member 2. Therefore, the motor 32 can drive the crank 35 and the connecting rod 43 to drive the four-bar linkage to move, so that the second section 4125 of the long rod 412 and the second section 4227 of the short rod 422 can rise and fall together with the movement of the four-bar linkage, thereby driving the lifting member 2 to rise and fall together.

[0272] In the retracted state, from the perspective of the X direction, the motor 32 drives the drive shaft 34 to rotate counterclockwise through the reduction box 33, which can drive the crank 35 to rotate in the counterclockwise direction, thereby driving the transmission rod 36 to move toward the -Z direction, and the whole rotates in the clockwise direction. The second end 362 of the transmission rod 36 drives the buffer rod 51 to rotate in the clockwise direction, and drives the short rod 422 to rotate in the clockwise direction through the torsion spring 52. The short rod 422 drives the long rod 412 to rotate in the clockwise direction through the connecting rod 43, so that the short rod 422 and the long rod 412 can drive the lifting member 2 to rise to the extended position together. The lifting member 2 rises to the extended position, which can be combined with the reference numeral 422. Fig.16A and Fig. 16B .

[0273] Please refer to Fig. 14B , Fig.16A and Fig. 16B , Fig.16A yes Figure 3B The schematic diagram of the structure of the driving assembly 3 and the connecting rod assembly 4 in the lifting mechanism 10 in some embodiments is shown. Fig. 16B yes Fig.16A A simplified diagram of the lifting mechanism 10 is shown.

[0274] In some embodiments, in the extended state, the driving motor 32 can reversely drive the crank 35 to rotate, so as to drive the transmission rod 36 to drive the buffer rod 51 to rotate, thereby achieving the descent of the lifting member 2.

[0275] In this embodiment, during the descending process of the lifting member 2 , the support block 517 in the buffer assembly 5 can abut against the limiting rib 425 in the short balance bar 42 , so that the buffer assembly 5 and the short balance bar 42 move together.

[0276] In the extended state, from the perspective of the X direction, the motor 32 drives the drive shaft 34 to rotate clockwise through the reduction box 33, which can drive the crank 35 to rotate in the clockwise direction, thereby driving the transmission rod 36 to move toward the Z direction and rotate in the counterclockwise direction as a whole. The transmission rod 36 drives the buffer rod 51 to rotate in the counterclockwise direction, and the buffer rod 51 drives the short balance rod 42 to rotate in the counterclockwise direction as a whole through the cooperation of the support block 517 and the limit rib 425, so that the short rod 422 rotates in the counterclockwise direction, and the short rod 422 drives the long rod 412 to rotate in the counterclockwise direction through the connecting rod 43, so that the short rod 422 and the long rod 412 can drive the lifting member 2 to descend to the initial position together. The descent of the lifting member 2 to the initial position can be combined with reference to Fig.15A and Fig. 15B .

[0277] Please refer to Figure 3A , Figure 4 and Fig.15A In some embodiments, the drive shaft 34 is rotatably connected to the drive fixing portion 13 of the base 1. The drive shaft 34 may include an output shaft 341 and a support shaft 342, the output shaft 341 and the support shaft 342 are coaxially arranged, the output shaft 341 is transmission-connected between the reduction box 33 and the crank 35, and the support shaft 342 is connected between the crank 35 and the drive fixing portion 13 of the base 1. In this embodiment, the support shaft 342 can improve the stability of the installation of the drive assembly 3, which is beneficial to the stability of the transmission of the drive assembly 3. In addition, the support shaft 342 can also pass through the auxiliary fixing hole 143 of the first fixing portion 14 of the base 1, further improving the stability of the installation of the drive assembly 3.

[0279] In some embodiments, when the lifting mechanism 10 is in the extended state, the angle formed by the line connecting the first end 361 of the transmission rod 36 and the second end 362 of the transmission rod 36 and the line connecting the first end 351 of the crank 35 and the second end 352 of the crank 35 is within the range of 180°±10° (see Fig. 17C α in .

[0280] For example, in the extended state, the lifting member 2 is subjected to external pressure in the -Z direction (see Fig. 17B The pressure F3 drives the lifting member 2 to retract in the -Z direction, thereby driving the long rod 412 to rotate counterclockwise around the first rotation axis 441, and driving the short rod 422 to rotate counterclockwise around the first rotation axis 444. When the short rod 422 rotates counterclockwise around the first rotation axis 444, it drives the short support rod 421 to squeeze the torsion spring 52 toward the bottom wall of the receiving groove 511 of the buffer rod 51, so as to compress the pin 52b of the torsion spring 52.

[0281] In this embodiment, the transmission rod 36 and the crank 35 are arranged at an angle α, and at this time, the transmission rod 36 and the crank 35 are at the dead point of the mechanism, so that the transmission rod 36 and the crank 35 will not rotate relative to each other, so that the transmission rod 36 and the crank 35 can jointly form a support for the buffer rod 51. Therefore, the bottom wall of the receiving groove 511 of the buffer rod 51 can form a support for the torsion spring 52. Under the action of the pressure F3, the torsion spring 52 will be compressed, and the transmission rod 36 will not drive the crank 35 to rotate, thereby preventing the crank 35 from driving the motor 32 to rotate, and preventing the motor 32 from passively rotating, so as to protect the motor 32.

[0282] In addition, the lifting member 2 can be lowered after receiving the pressure F3 in the -Z direction, and the torsion spring 52 can buffer the pressure F3 by deformation in this process to prevent the lifting member 2 from being hit hard. In addition, after the lifting member 2 is lowered, the base can provide protection for the lifting member 2 to prevent the lifting member 2 from being further hit. In addition, after the pressure F3 on the lifting member 2 is removed, the torsion spring 52 can drive the short rod 422 and the long rod 412 to rotate together through the force of deformation recovery, so as to drive the lifting member 2 to return to the extended state.

[0283] The value of the angle α may be, but is not limited to, 170°, 175°, 180°, 185°, 190°, or other values ​​between 170° and 190°, as long as the transmission rod 36 and the crank 35 can form a dead point of the mechanism when in the extended state.

[0284] The pressure F3 may come from the falling of the electronic device 1000, the collision between the electronic device 1000 and the outside world, the squeezing between the electronic device 1000 and the outside world, etc.

[0285] Please refer to Figure 5B , Fig.18A and Fig.18B , Fig.18A yes Figure 3A The cross-sectional structure diagram of the lifting mechanism 10 is shown along the section BB. Fig.18B yes Figure 3B The lifting mechanism 10 is shown as a schematic cross-sectional structure diagram along CC.

[0286] In some embodiments, at least part of the lifting member 2 is located in the inner space 11 of the base 1. The decorative member 7 can be installed on the base 1, the decorative member 7 surrounds the lifting member 2, and blocks the gap between the lifting member 2 and the top wall 1a of the base 1. For example, the decorative member 7 may include a first part 7a and a second part 7b, the first part 7a is embedded in the sink 11a of the top wall 1a, the second part 7b is connected to the first part 7a and is located on the top side of the top wall 1a of the base 1, and the second part 7b covers the side wall of the sink 11a. Among them, the decorative member 7 has a receiving hole 71. The receiving hole 71 accommodates the lifting member 2 and allows the lifting member 2 to pass through, so as to achieve the rise and fall of the lifting member 2.

[0287] In this embodiment, the decorative member 7 blocks the gap between the base 1 and the lifting member 2, thereby playing a role of decoration and improving the appearance. In addition, the decorative member 7 can also prevent debris, dust, etc. from entering the gap between the base 1 and the lifting member 2, playing a role of sealing and dustproofing.

[0288] In some embodiments, the waterproof component 6 can be located in the gap between the lifting component 2 and the base 1, so that the waterproof component 63 can be blocked by the decorative component 7, thereby avoiding direct contact between the waterproof component 6 and the external air, slowing down the oxidation and corrosion of the waterproof component 6, and thereby improving the service life of the waterproof component 6.

[0289] Exemplarily, the waterproof assembly 6 may include a first waterproof ring 61, a second waterproof ring 62 and a waterproof member 63. The first waterproof ring 61 and the second waterproof ring 62 are connected to both ends of the waterproof member 63. The first waterproof ring 61 is sleeved on the lifting member 2 and fixed to the limiting surface 211. The second waterproof ring 62 is fixed to the bottom wall of the sink 11a. Among them, the waterproof member 63 is also roughly annular or ring-shaped.

[0290] In this embodiment, the first waterproof ring 61 , the second waterproof ring 62 and the waterproof member 63 are provided to block the gap between the lifting member 2 and the base 1 , thereby achieving a waterproof and dustproof sealing effect to protect the internal structure of the electronic device 1000 .

[0291] Exemplarily, the waterproof member 63 can be deformed to follow the movement of the lifting member 2. In this embodiment, the lifting member 2 can drive the first waterproof ring 61 to move together through the limiting surface 211 during the lifting process, and the first waterproof ring 61 drives the waterproof member 63 to deform, so that the waterproof member 63 can move together with the lifting member 2, so that the waterproof component 6 can block the gap between the lifting member 2 and the base 1 during the lifting process of the lifting member 2, thereby achieving the waterproof and dustproof sealing effect of the lifting member 2 during the lifting process.

[0292] In some other embodiments, the waterproof component 6 may not be provided with the first waterproof ring 61 and the second waterproof ring 62, but one end of the waterproof component 63 is directly fixed to the lifting component 2, and the other end is directly fixed to the base 1. The specific implementation structure of the waterproof component 6 is not strictly limited in the embodiment of the present application.

[0293] Please refer to Figure 5B , Fig.19A and Fig.19B , Fig.19A yes Figure 3A The structural schematic diagram of the lifting mechanism 10 shown in FIG. 1 is another perspective view. Fig.19B yes Figure 3A The cross-sectional structure diagram of the lifting mechanism 10 is shown along DD.

[0294] In some embodiments, a retracting stop 17 is provided on the bottom side of the base 1. The retracting stop 17 is connected to the bottom side of the second side wall 1c and protrudes toward the inner space of the shell. When the lifting mechanism 10 is in the retracted state, the first boss 251 of the lifting member 2 abuts against the top side of the retracting stop 17.

[0295] In this embodiment, the retraction limit platform 17 is disposed on the bottom side of the base 1, so that when the lifting member 2 is converted from the extended state to the retracted state, the top side surface of the retraction limit platform 17 can limit the lifting member 2 to prevent the lifting member 2 from over-retracting and colliding with other components inside the electronic device 1000. In addition, since the lifting member 2 is in the retracted state in most cases, the retraction limit platform 17 can support the lifting member 2 to maintain the overall structural stability of the lifting mechanism 10.

[0296] Please refer to Figure 5A , Figure 5B and Fig. 20 , Fig. 20 yes Figure 3B The cross-sectional structure diagram of the lifting mechanism 10 is shown along line EE.

[0297] In some embodiments, the base 1 may further include an extension limit platform 18, the extension limit platform 18 and the retraction limit platform are arranged opposite to each other, and the first boss 251 and the second boss 261 are located between the extension limit platform 18 and the retraction limit platform. When the lifting mechanism 10 is in the extended state, the first boss 251 and the second boss 261 abut against the bottom side of the extension limit platform 18.

[0298] In this embodiment, the extension limit platform 18 is arranged close to the top side of the base 1, so that when the lifting member 2 is converted from the retracted state to the extended state, the bottom surface of the extension limit platform 18 can limit the lifting member 2 to avoid excessive extension of the lifting member 2, thereby ensuring that the extension size of the lifting member 2 is consistent each time, thereby improving the stability of the electronic device 1000 in the telephoto state.

[0299] The bottom wall of the trough 11a is connected to the extension limit platform 18, so that the bottom wall of the trough 11a can be connected to the first side wall 1b, the second side wall 1c and the third side wall 1d through the extension limit platform 18, thereby improving the structural strength of the bottom wall of the trough 11a. The bottom wall of the trough 11a is connected to the extension limit platform 18, and the area of ​​the extension limit platform 18 is increased, which is conducive to limiting the lifting member 2.

[0300] Please refer to Figure 5A , Fig.21A and Fig.21B , Fig.21A yes Figure 3A The schematic diagram of the connection structure between the connecting rod assembly 4 in the lifting mechanism 10 and the lifting member 2 in other embodiments is shown. Fig.21B yes Figure 3B The schematic diagram of the connection structure between the connecting rod assembly 4 and the lifting member 2 in other embodiments of the lifting mechanism 10 is shown. Fig.21A The two rods of the solid triangle connection are fixedly connected to each other. Fig.21B The midpoint dashed line indicates the lifting member 2 in the initial position. This embodiment may include most of the technical features of the previous embodiment, and the following mainly describes the difference between the two, and most of the same technical features of the two are not repeated.

[0301] In some embodiments, the first fixing portion 14 and the second fixing portion 15 of the base 1 are arranged at intervals, and the portion of the base 1 between the first fixing portion 14 and the second fixing portion 15 can be used as a fixing rod 16. The long rod 412 may include a first section 4124 and a second section 4125, the first section 4124 of the long rod 412 is rotatably connected between the first fixing portion 14 and the connecting rod 43, one end of the second section 4125 of the long rod 412 is fixedly connected to the first section 4124 of the long rod 412, and the other end of the second section 4125 of the long rod 412 is rotatably connected to the first end 25 of the lifting member 2. The short rod 422 may include a first section 4226 and a second section 4227. The first section 4226 of the short rod 422 is rotatably connected between the second fixing portion 15 and the connecting rod 43, one end of the second section 4227 of the short rod 422 is fixedly connected to the first section 4226 of the short rod 422, and the other end of the second section 4227 of the short rod 422 is rotatably connected to the second end 26 of the lifting member 2.

[0302] Among them, in the YZ plane, the length of the fixed rod 16 is equal to the length of the connecting rod 43, and the fixed rod 16, the first section 4124 of the long rod 412, the connecting rod 43 and the first section 4226 of the short rod 422 are connected end to end to form a parallelogram. The distance between the rotation center of the first end 25 of the lifting member 2 and the second section 4125 of the long rod 412 and the rotation center of the second end 26 of the lifting member 2 and the second section 4227 of the short rod 422 is equal to the length of the connecting rod 43, and the connecting line of the two rotation centers of the lifting member 2 is parallel to the fixed rod 16.

[0303] Exemplarily, the axial direction of the lifting member 2 in the retracted state is parallel to the Z direction. The first end 25 of the lifting member 2 in the extended state and the line connecting the first end 25 of the lifting member 2 in the retracted state are parallel to the Z direction. The second end 26 of the lifting member 2 in the extended state and the line connecting the second end 26 of the lifting member 2 in the retracted state are parallel to the Z direction.

[0304] Among them, since the fixing rod 16, the first section 4124 of the long rod 412, the connecting rod 43 and the first section 4226 of the short rod 422 are connected end to end to form a parallelogram, the angle of rotation of the long rod 412 around the first fixing portion 14 and the angle of rotation of the short rod 422 around the second fixing portion 15 are consistent during the lifting process of the lifting member 2. In other words, the line connecting the first end 25 of the lifting member 2 and the first fixing portion 14 in the extended state and the line connecting the first end 25 of the lifting member 2 and the first fixing portion 14 in the retracted state form a first angle, and the line connecting the second end 26 of the lifting member 2 and the second fixing portion 15 in the extended state and the line connecting the second end 26 of the lifting member 2 and the second fixing portion 15 in the retracted state form a second angle, and the first angle is equal to the second angle.

[0305] Among them, since the spacing between the first fixing portion 14 and the second fixing portion 15 in the Y direction is equal to the spacing between the first end 25 of the lifting member 2 and the second end 26 of the lifting member 2, the length of the line connecting the first fixing portion 14 and the first end 25 of the lifting member 2 is equal to the length of the line connecting the second fixing portion 15 and the second end 26 of the lifting member 2. In other words, the radius of rotation of the first end 25 of the lifting member 2 around the first fixing portion 14 is equal to the radius of rotation of the second end 26 of the lifting member 2 around the second fixing portion 15. According to the arc length theorem, during the lifting process, the arc length of rotation of the first end 25 of the lifting member 2 around the first fixing portion 14 is equal to the arc length of rotation of the second end 26 of the lifting member 2 around the second fixing portion 15. Therefore, the path of rotation of the first end 25 of the lifting member 2 around the first fixing portion 14 is the same as the path of rotation of the second end 26 of the lifting member 2 around the second fixing portion 15.

[0306] In this embodiment, since the connecting rod 43 connects the long rod 412 and the short rod 422, the movements of the long rod 412 and the short rod 422 are consistent, and since the rotation path of the long rod 412 around the first fixed part 14 is the same as the rotation path of the short rod 422 around the second fixed part 15, during the lifting process of the lifting member 2, the movement paths of the first end 25 and the second end of the lifting member 2 are arc-shaped, and the offset movement in the Y direction is consistent, so that the first end 25 of the lifting member 2 and the second end 26 of the lifting member 2 do not need to be provided with a sliding groove for offset design, and the lifting member 2 as a whole can maintain balance, so that the bottom side of the lifting member 2 is always parallel to the XY plane, thereby improving the smoothness of the lifting and lowering of the lifting member 2.

[0307] Please refer to Fig. 8A , Figure 8B and Fig. 10A In some other embodiments, the connecting rod assembly 4 may include a group of transmission members 44, and the lifting mechanism 10 may further include a guide member (not shown in the figure). The transmission member 44 and the guide member may be located at the first side 27 and the second side 28 of the lifting member 2, respectively. The connecting rod assembly 4 and the base 1 together constitute a four-bar linkage to drive the lifting member 2 to move up and down, and the guide member is a guide track of the lifting member 2 during the lifting process, so that when the connecting rod assembly 4 drives one side of the lifting member 2 to move up and down, the other side of the lifting member 2 can move up and down together under the guidance of the guide member.
