Description

Technical Field

[0001] The utility model relates to the technical field of vehicle door handles, in particular to a vehicle door handle structure and a vehicle. Background Art

[0002] With the rapid development of the automobile industry, consumers have increasingly higher requirements for vehicle performance, and their expectations for appearance are also constantly upgrading. The traditional door handle design, due to its obvious protrusion on the side of the car, can no longer meet contemporary aesthetic standards. Therefore, combining traditional car door handles with electronic technology to achieve a hidden handle design has become an inevitable trend in the development of the industry. In addition, the external handle protrudes from the outer panel of the door, which also has a certain negative impact on the wind resistance performance of the side of the vehicle. Therefore, there is an urgent need for an external handle design that can be hidden inside the car body to meet the dual needs of modern consumers for vehicle appearance and performance. Utility Model Content

[0003] 1. Technical issues to be resolved

[0004] The technical problem to be solved by the utility model is to provide a door handle structure and a vehicle, which, under the action of a driving mechanism and a first pushing mechanism, will drive the second pushing mechanism and the swing arm to move, thereby driving the handle to move, and can hide the handle inside the vehicle body, and has a high degree of automation and is easy to operate.

[0005] (II) Technical solution

[0006] The solution adopted by the utility model to solve the above technical problems is a vehicle door handle structure, comprising

[0007] a housing having an opening at one end;

[0008] a handle that can be flush with the opening and can extend out of the opening;

[0009] A driving mechanism is disposed in the housing;

[0010] A first pushing mechanism, one end of which is connected to the driving mechanism, and the driving mechanism is capable of driving the first pushing mechanism to move;

[0011] A second driving mechanism, one end of which is connected to the first driving mechanism, and the other end of which is connected to the handle, and the first driving mechanism can drive the second driving mechanism to move;

[0012] A swing arm, one end of which is connected to the handle and the other end of which is rotatably connected to the shell, and the first pushing mechanism can drive the swing arm to rotate;

[0013] The second pushing mechanism and the swing arm can drive the handle to move out of the opening.

[0014] In some embodiments, the shell includes a bottom cover and a cover body arranged on the bottom cover, which is convenient for assembly and disassembly; the opening is arranged on the cover body, and after the cover body is assembled on the bottom cover, a receiving space for receiving the driving mechanism, the first pushing mechanism, the second pushing mechanism, and the swing arm is formed; the driving mechanism includes a telescopic rod that can be extended and retracted, and the telescopic rod is fixedly connected to the first pushing mechanism to drive it to move back and forth in the length direction, thereby controlling the extension and retraction of the handle, and the degree of automation is high; the driving mechanism is engaged with the bottom cover through a card block, which can ensure the stability of the driving mechanism during operation, and then the stability of the operation of the first pushing mechanism, the second pushing mechanism and the swing arm can be ensured, thereby ensuring the stability of the handle movement process and improving the sense of embodiment.

[0015] By adopting the above scheme, under the action of the driving mechanism and the first pushing mechanism, the second pushing mechanism and the swing arm are driven to move, thereby driving the handle to move, so that the handle can be hidden inside the vehicle body, and the degree of automation is high and the operation is convenient.

[0016] In some embodiments, a travel limiter is connected to the first pushing mechanism, and the travel limiter can limit the moving travel of the first pushing mechanism to control the movement state of the handle.

[0017] In some embodiments, a signal receiver that can be connected to the stroke limiter signal is also arranged on the shell. When the stroke limiter moves with the first pushing mechanism, the signal connector will be triggered, so as to accurately detect the movement stroke, and then accurately control the movement state of the handle, with a high degree of automation; the stroke limiter is fixed to the side wall of the first pushing mechanism by screws so as to better connect with the signal of the signal receiver.

[0018] By adopting the above scheme, the movement stroke of the first pushing mechanism can be controlled separately by setting the movement stroke of the stroke limiter, and the movement stroke of the second pushing mechanism and the swing arm can be controlled, thereby controlling the movement state of the handle; when the driving mechanism drives the first pushing mechanism to move to the first stroke, the stroke limiter will give a signal to the controller, and at this time, the handle is driven to extend parallel to the opening in an extended state; when the driving mechanism drives the first pushing mechanism to move to the second stroke, the stroke limiter will give a signal to the controller, and at this time, the handle is driven to be in an unlocked state with one end tilted up, so as to more accurately control the extension and unlocking of the handle; at the same time, during the reverse movement, the return of the handle can also be accurately controlled.

[0019] In some embodiments, the second pushing mechanism includes two second pushing rods arranged at intervals, and a second connecting rod connected between the two second pushing rods; wherein, a first limiting member is arranged in the shell between the two pushing rods, and the first limiting member is provided with a limiting groove for limiting the movement trajectory of the second pushing rod, and the second connecting rod is adapted in the limiting groove and can move in the limiting groove.

[0020] In some embodiments, the second connecting rod is provided at one end of the second pushing rod close to the first pushing mechanism, and the other end is rotatably connected to the part of the handle extending into the shell; so that when the second connecting rod moves along the limiting groove, the handle will be driven to move up and down.

[0021] In some embodiments, the limit groove includes a straight line segment and an arc segment; the straight line segment is arranged close to the first pushing mechanism; when the second connecting rod moves in the straight line segment, the handle can switch between a hidden state flush with the opening and an extended state extending parallel to the opening; when the second connecting rod moves in the arc segment, the handle can switch between an extended state extending parallel to the opening and an unlocked state with one end tilted up.

[0022] By adopting the above scheme, when the second connecting rod abuts against the side of the straight segment away from the arc segment, the handle is in a hidden state flush with the opening; when the second connecting rod moves to the connection between the straight segment and the arc segment, the handle is in an extended state parallel to the opening; when the second connecting rod moves to the point where it abuts against the side of the arc segment away from the straight segment, the handle is in a state where one end is raised so that the operator can grasp and pull the handle to unlock the lock cylinder.

[0023] In some embodiments, the first limit member is rotatably connected to the shell, and the first limit member can move toward the direction close to the opening under the action of the handle and the second pushing mechanism, so that the handle can unlock the lock cylinder; and the shell is provided with a reset mechanism above the first limit member for resetting the first limit member and the handle.

[0024] In some embodiments, the limiting member is an arc-shaped structure as a whole; the upper and lower ends of the limiting member on one side close to the first pushing mechanism are respectively rotatably connected to the shell to improve its stability.

[0025] By adopting the above scheme, after the handle is in an unlocked state with one end tilted up under the action of the second pushing mechanism and the swing arm, pulling the tilted end of the handle will drive the second connecting rod to move, thereby causing the first limit member to rotate upward relatively, thereby achieving the purpose of unlocking the lock cylinder; after the unlocking is completed, the reset mechanism will reset the first limit member and the handle, so that the handle is restored to the unlocked state with one end tilted up, which is convenient for subsequent control of the handle to the hidden state.

[0026] In some embodiments, the first limiting member includes a shaft portion, and the shaft portion is rotatably connected to the shell through a pin shaft; the reset mechanism includes a first reset member and a second reset member rotatably connected to the shell, and a first torsion spring sleeved on the first reset member and a second torsion spring sleeved on the second reset member, and the first reset member and the second reset member are coaxially arranged; and, the first reset member includes a first abutting portion that can abut against an end of the shaft portion away from the first pushing mechanism, and the second reset member includes a second abutting portion that can abut against an end of the second connecting rod close to the opening; the first torsion spring can give the first reset member a tendency to move its first abutting portion in a direction close to the first pushing mechanism, and the second torsion spring can give the second reset member a tendency to move its second abutting portion in a direction away from the opening.

[0027] In some embodiments, the shaft portion is arranged at the lower end of the first limiting member, one end of the first torsion spring abuts against the shell, and the other end abuts against the first abutting portion; the end of the second reset member away from the first reset member is connected to a mounting member for installing the second torsion spring, and the mounting member is relatively arranged on the outside of the shell, one end of the second torsion spring abuts against the shell, and the other end abuts against the mounting member.

[0028] With the above scheme, after the handle is in an unlocked state with one end tilted up under the action of the second pushing mechanism and the swing arm, pulling the tilted end of the handle will drive the second connecting rod to move, so that the first limit member rotates relatively upward to achieve the purpose of unlocking the lock cylinder. In this process, the first abutting portion will relatively move in the direction away from the first unlocking mechanism and in the upward direction under the action of the shaft portion, and the second abutting portion will relatively move in the direction close to the opening under the action of the second connecting rod. At the same time, the first torsion spring and the second torsion spring will store energy; and after the unlocking is completed, the handle is released, and the first torsion spring will give the first abutting portion an action force to move in the direction close to the first pushing mechanism, and drive the shaft portion of the first limit member to move in the direction close to the first pushing mechanism to reset; at the same time, the second torsion spring will give the second abutting portion an action force to move in the direction away from the opening, and drive the second pushing rod and the second connecting rod to move in the direction away from the opening, and synchronously drive the handle to move in the direction close to the opening, so that it returns to the unlocked state with one end tilted up.

[0029] In some embodiments, the first pushing mechanism includes two first pushing rods arranged at intervals, and the swing arm is arranged between the two first pushing rods; when the first pushing rod moves along its length direction, it can give the swing arm a force to make it move in a direction close to the opening.

[0030] In some embodiments, the first pushing mechanism also includes a first connecting rod connected to one end of the two first pushing rods close to the driving mechanism, and the telescopic rod of the driving mechanism is fixedly connected to the first connecting rod so that the telescopic movement of the driving mechanism can drive the linear reciprocating movement of the first pushing rod; the ends of the two first pushing rods away from the driving mechanism are respectively contacted and connected with the two second pushing rods so that the first pushing rod can push the movement of the second pushing rod; and when the telescopic rod of the driving mechanism drives the first pushing rod to move back to its position, the first pushing rod is separated from the second pushing rod, and the second pushing rod will move back to its position under the action of the first torsion spring and the second torsion spring, so that the raised end of the handle moves downward until the two ends are flush; the continued backward movement of the first pushing rod will cause its first connecting rod to be separated from the swing arm, and the swing arm will move downward synchronously under the action of the third torsion spring, and at the same time, the second pushing rod will continue to move backward under the action of the first torsion spring and the second torsion spring, so that the swing arm and the second pushing rod will drive the handle to move downward synchronously until it is flush with the opening to a hidden state.

[0031] In some embodiments, the first push rod includes a first section, a second section, and a third section connected in sequence; the first connecting rod is connected to the side of the first section facing away from the second section; the height of the first section relative to the bottom cover is higher than the height of the third section relative to the bottom cover, so that the first section is closer to the handle and the first connecting rod is closer to the swing arm. In the process of the driving mechanism extending to drive the first push rod to move, the first connecting rod can give the swing arm a force to make it move.

[0032] In some embodiments, a second limit member for limiting the movement trajectory of the swing arm is provided at one end of the shell facing away from the opening; the swing arm is provided with a slot, and the second limit member is vertically adapted in the slot, so that the second limit member can limit the movement of the swing arm in the up and down directions.

[0033] In some embodiments, a third torsion spring is provided at the rotational connection between the second limit member and the shell, one end of the third torsion spring abuts against the shell, and the other end abuts against the swing arm, which can give the swing arm a tendency to rotate downward.

[0034] In some embodiments, the swing arm includes an inclined end surface that cooperates with the first connecting rod, and the inclined end surface is inclined from top to bottom in a direction that is continuously away from the driving mechanism.

[0035] By adopting the above scheme, in the process of the telescopic rod of the driving mechanism extending and driving the first pushing rod to move, the first connecting rod can exert a force on the inclined end surface of the swing arm to make the swing arm move upward, and under the action of the second limiting member, the movement of the swing arm along the length direction of the first pushing rod is restricted, so that it moves upward relatively, thereby driving one end of the handle to move upward relatively; at the same time, under the action of the second pushing rod, the other end of the handle is driven to move upward synchronously, so as to realize that the handle extends out of the opening in parallel to the extended state, during which the second connecting rod moves along the straight line section of the limiting groove of the first limiting member; and under the action of the second limiting member of the second pushing rod, the second connecting rod moves along the straight line section of the limiting groove of the first limiting member; and under the action of the second limiting member of the second pushing rod, the second connecting rod moves along the straight line section of the limiting groove of the first limiting member; and under the action of the second limiting member of the second pushing rod, the second connecting rod moves along the straight line section of the limiting groove of the first limiting member. When the connecting rod moves along the arc segment of the limiting groove of the first limiting member and drives the handle to continue to move, the first connecting rod has been separated from the inclined end surface and placed at the bottom end of the swing arm, and the swing arm will not be driven to move, and the end of the handle connected to the swing arm will not be driven to move. If the end of the handle connected to the second push rod continues to move, an unlocked state with one end raised will be achieved; and in the process of the handle changing from an extended state to a hidden state, the first connecting rod moves from the bottom end of the swing arm to under its inclined end surface, and the third torsion spring is released, and under the action of the third torsion spring, the swing arm is driven to move downward, thereby pulling the handle downward, so that the handle moves downward synchronously to the hidden state.

[0036] In some embodiments, the swing arm is provided with damping teeth around the connection between the swing arm and the handle, and the handle is provided with a damping wheel capable of engaging with the damping teeth. On the one hand, by providing the damping wheel and the damping teeth, it is possible to prevent the handle from pinching the hand due to too fast a resetting action of the handle when the handle is switched from an unlocked state to an extended state. At the same time, the meshing transmission of the damping teeth and the damping wheel can improve the comfort of movement. On the other hand, when the swing arm is swinging, the damping wheel and the damping teeth are meshed and rotated, and the locking force is good, and resistance will be encountered. This can not only prevent the swing arm from colliding with other components due to too fast a swinging speed, but also prevent the handle from switching to an unlocked state due to malfunction of the swing arm during the shaking of the vehicle.

[0037] In some embodiments, an ambient light is disposed at an edge of the housing close to the opening.

[0038] With the above solution, the ambient light will automatically start at low brightness to provide lighting, help identify the handle operation area, and enhance the user experience.

[0039] In some embodiments, a heating wire is further provided in the handle, and the heating wire is arranged circumferentially along the inner wall of the edge of the handle; when in a low temperature environment in winter, the heating wire can effectively heat the handle, thereby melting any ice that may form; this can prevent the handle from being unable to open or suffering structural damage due to freezing, thereby ensuring the continued reliable operation of the product.

[0040] In some embodiments, the door handle structure also has an ice-breaking mode; under normal conditions, the driving force for pushing the handle is a fixed value, and the force value is relatively low, so the handle can be lifted out of the door smoothly and evenly; however, if the fixed value of the driving force cannot lift the handle out of the door, a signal will be given to the controller, and the controller will increase the force value of the driving force and switch to the ice-breaking mode, using the maximum force value to drive the handle. If the handle still cannot be driven out of the door in the ice-breaking mode, a signal will be given to the controller, and the controller will control the heating wire to start, so that it can run to heat the handle.

[0041] The solution adopted by the utility model to solve the above technical problems is a vehicle, such as the above-mentioned door handle structure; the handle can be hidden inside the vehicle body, and the degree of automation is high and the operation is convenient.

[0042] (III) Beneficial effects

[0043] Compared with the prior art, the utility model designs a door handle structure and a vehicle.

[0044] (1) Under the action of the driving mechanism and the first pushing mechanism, the utility model drives the second pushing mechanism and the swing arm to move, thereby driving the handle to move, so that the handle can be hidden inside the vehicle body, and has a high degree of automation and is easy to operate;

[0045] (2) The utility model can control the movement stroke of the first pushing mechanism respectively by setting the movement stroke of the stroke limiter, and can control the movement stroke of the second pushing mechanism and the swing arm, thereby controlling the movement state of the handle; when the driving mechanism drives the first pushing mechanism to move to the first stroke, the stroke limiter will give a signal to the controller, at this time, the handle is driven to extend parallel to the opening to the extended state; when the driving mechanism drives the first pushing mechanism to move to the second stroke, the stroke limiter will give a signal to the controller, at this time, the handle is driven to the unlocked state with one end tilted up, so as to more accurately control the extension and unlocking of the handle; at the same time, when moving in the reverse direction, the return of the handle can also be accurately controlled;

[0046] (3) In the present invention, when the second connecting rod abuts against the side of the straight segment away from the arc segment, the handle is in a hidden state flush with the opening; when the second connecting rod moves to the connection between the straight segment and the arc segment, the handle is in an extended state parallel to the opening; when the second connecting rod moves to the point where it abuts against the side of the arc segment away from the straight segment, the handle is in a tilted state at one end so that the operator can grasp and pull the handle to unlock the lock cylinder;

[0047] (4) After the handle of the utility model is in an unlocked state with one end tilted up under the action of the second pushing mechanism and the swing arm, pulling the tilted end of the handle will drive the second connecting rod to move, so that the first limiting member will rotate upward relatively, thereby achieving the purpose of unlocking the lock cylinder. In this process, the first abutting portion will move relatively in the direction away from the first unlocking mechanism and in the upward direction under the action of the shaft portion, and the second abutting portion will move relatively in the direction close to the opening under the action of the second connecting rod. At the same time, the first torsion spring and the second torsion spring will store energy. After the unlocking is completed, the handle is released, and the first torsion spring will give the first abutting portion an action force to move in the direction close to the first pushing mechanism, and drive the shaft portion of the first limiting member to move in the direction close to the first pushing mechanism to reset. At the same time, the second torsion spring will give the second abutting portion an action force to move in the direction away from the opening, and drive the second pushing rod and the second connecting rod to move in the direction away from the opening, and synchronously drive the handle to move in the direction close to the opening, so that it returns to the unlocked state with one end tilted up.

[0048] (5) The utility model provides a damping wheel and a damping tooth, so as to avoid the handle being pinched by the hand due to the excessively fast resetting action of the handle when the handle is switched from the unlocked state to the extended state. At the same time, the meshing transmission of the damping tooth and the damping wheel can improve the comfort of movement. On the other hand, when the swing arm is swinging, the damping wheel and the damping tooth are meshed and rotated, and the locking force is good, and resistance is encountered. This can not only avoid the swing arm from colliding with other parts due to the excessively fast swinging speed, but also avoid the handle being switched to the unlocked state due to the erroneous movement of the swing arm during the shaking of the vehicle.

[0049] (6) The utility model sets an ambient light, which will automatically start at low brightness to provide lighting, help identify the handle operation area, and improve the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0076] In some embodiments, the second pushing mechanism 500 includes two second pushing rods 50 arranged at intervals, and a second connecting rod 51 connected between the two second pushing rods 50; wherein, a first limiting member 101 is provided between the two pushing rods in the housing 100, and the first limiting member 101 is provided with a limiting groove 1011 for limiting the movement trajectory of the second pushing rod 50, and the second connecting rod 51 is adapted in the limiting groove 1011 and can move in the limiting groove 1011. In some embodiments, the second connecting rod 51 is provided at one end of the second pushing rod 50 close to the first pushing mechanism 400, and the other end is rotatably connected to the part of the handle 200 extending into the housing 100; so that when the second connecting rod 51 moves along the limiting groove 1011, the handle 200 will be driven to move up and down. In some embodiments, the limiting groove 1011 includes a straight segment 1011a and an arc segment 1011b; the straight segment 1011a is arranged close to the first pushing mechanism 400; when the second connecting rod 51 moves in the straight segment 1011a, the handle 200 can switch between a hidden state flush with the opening 10 and an extended state extending parallel to the opening 10; when the second connecting rod 51 moves in the arc segment 1011b, the handle 200 can switch between an extended state extending parallel to the opening 10 and an unlocked state with one end tilted up. By adopting the above scheme, when the second connecting rod 51 abuts against the side of the straight segment 1011a away from the arc segment 1011b, the handle 200 is in a hidden state flush with the opening 10; when the second connecting rod 51 moves to the connection between the straight segment 1011a and the arc segment 1011b, the handle 200 is in an extended state parallel to the opening 10; when the second connecting rod 51 moves to the point where it abuts against the side of the arc segment 1011b away from the straight segment 1011a, the handle 200 is in a state where one end is raised, so that the operator can grasp and pull the handle 200 to unlock the lock cylinder.

[0077] In some embodiments, the first stopper 101 is rotatably connected to the housing 100, and the first stopper 101 can move toward the direction close to the opening 10 under the action of the handle 200 and the second pushing mechanism 500, so that the handle 200 can unlock the lock cylinder; and the housing 100 is provided with a reset mechanism 800 for resetting the first stopper 101 and the handle 200 above the first stopper 101. In some embodiments, the stopper is an arc-shaped structure as a whole; the upper and lower ends of the side close to the first pushing mechanism 400 are rotatably connected to the housing 100 respectively to improve its stability. By adopting the above scheme, after the handle 200 is in an unlocked state with one end tilted up under the action of the second pushing mechanism 500 and the swing arm 600, pulling the tilted end of the handle 200 will drive the second connecting rod 51 to move, thereby causing the first limit member 101 to rotate upward relatively, thereby achieving the purpose of unlocking the lock cylinder; after the unlocking is completed, the reset mechanism 800 will reset the first limit member 101 and the handle 200, so that the handle 200 is restored to the unlocked state with one end tilted up, which is convenient for subsequent control of the handle 200 to the hidden state. In some embodiments, the first limiting member 101 includes a shaft portion 1012, and the shaft portion 1012 is rotatably connected to the shell 100 through a pin; the reset mechanism 800 includes a first reset member 80 and a second reset member 81 rotatably connected to the shell 100, and a first torsion spring 82 sleeved on the first reset member 80 and a second torsion spring 83 sleeved on the second reset member 81, and the first reset member 80 and the second reset member 81 are coaxially arranged; and the first reset member 80 includes a first abutting portion 801 that can abut against an end of the shaft portion 1012 away from the first pushing mechanism 400, and the second reset member 81 includes a second abutting portion 811 that can abut against an end of the second connecting rod 51 close to the opening 10; the first torsion spring 82 can give the first reset member 80 a tendency to move its first abutting portion 801 in a direction close to the first pushing mechanism 400, and the second torsion spring 83 can give the second reset member 81 a tendency to move its second abutting portion 811 in a direction away from the opening 10. In some embodiments, the shaft portion 1012 is disposed at the lower end of the first limiting member 101, one end of the first torsion spring 82 abuts against the shell 100, and the other end abuts against the first abutting portion 801; the end of the second reset member 81 away from the first reset member 80 is connected to a mounting member 812 for mounting the second torsion spring 83, and the mounting member 812 is relatively disposed on the outside of the shell 100, one end of the second torsion spring 83 abuts against the shell 100, and the other end abuts against the mounting member 812.By adopting the above scheme, after the handle 200 is in an unlocked state with one end tilted up under the action of the second pushing mechanism 500 and the swing arm 600, pulling the tilted end of the handle 200 will drive the second connecting rod 51 to move, so that the first limiting member 101 rotates upward relatively, thereby achieving the purpose of unlocking the lock cylinder. In this process, the first abutting portion 801 will move relatively in a direction away from the first unlocking mechanism and in an upward direction under the action of the shaft portion 1012, and the second abutting portion 811 will move relatively in a direction close to the opening 10 under the action of the second connecting rod 51. At the same time, the first torsion spring 82 and the second torsion spring 83 will store energy. After unlocking is completed, the handle 200 is released, and the first torsion spring 82 will give a force to the first abutment portion 801, causing it to move in the direction close to the first pushing mechanism 400, and drive the shaft portion 1012 of the first limiting member 101 to move in the direction close to the first pushing mechanism 400 to reset; at the same time, the second torsion spring 83 will give a force to the second abutment portion 811, causing it to move in the direction away from the opening 10, and drive the second pushing rod 50 and the second connecting rod 51 to move in the direction away from the opening 10, and simultaneously drive the handle 200 to move in the direction close to the opening 10, so that it returns to the unlocked state with one end raised.

[0078] In some embodiments, the first pushing mechanism 400 includes two first pushing rods 40 arranged at intervals, and the swing arm 600 is arranged between the two first pushing rods 40; when the first pushing rod 40 moves along its length direction, it can give the swing arm 600 a force to make it move in a direction close to the opening 10. In some embodiments, the first pushing mechanism 400 also includes a first connecting rod 41 connected to one end of the two first pushing rods 40 close to the driving mechanism 300, and the telescopic rod 30 of the driving mechanism 300 is fixedly connected to the first connecting rod 41, so that the telescopic movement of the driving mechanism 300 can drive the linear reciprocating movement of the first pushing rod 40; the ends of the two first pushing rods 40 facing away from the driving mechanism 300 are respectively in contact with and connected to the two second pushing rods 50, so that the first pushing rod 40 can push the movement of the second pushing rod 50; and after the telescopic rod 30 of the driving mechanism 300 drives the first pushing rod 40 When moving back, the first push rod 40 disengages from the second push rod 50, and the second push rod 50 will move back under the action of the first torsion spring 82 and the second torsion spring 83, thereby realizing that the raised end of the handle 200 moves downward until the two ends are flush; the continued backward movement of the first push rod 40 will cause its first connecting rod 41 to disengage from the swing arm 600, and the swing arm 600 will move downward synchronously under the action of the third torsion spring 103. At the same time, the second push rod 50 will continue to move backward under the action of the first torsion spring 82 and the second torsion spring 83, so that the swing arm 600 and the second push rod 50 will drive the handle 200 to move downward synchronously until it is flush with the opening 10 to a hidden state. In some embodiments, the first push rod 40 includes a first section 401, a second section 402 and a third section 403 connected in sequence; the first connecting rod 41 is connected to the side of the first section 401 away from the second section 402; the height of the first section 401 relative to the bottom cover 11 is higher than the height of the third section 403 relative to the bottom cover 11, so that the first section 401 is closer to the handle 200 and the first connecting rod 41 is closer to the swing arm 600, and in the process of the driving mechanism 300 extending to drive the first push rod 40 to move, the first connecting rod 41 can give the swing arm 600 a force to move it. In some embodiments, the end of the housing 100 away from the opening 10 is provided with a second stopper 102 for limiting the movement trajectory of the swing arm 600; the swing arm 600 is provided with a slot 60, and the second stopper 102 is vertically adapted in the slot 60, so that the second stopper 102 can limit the movement of the swing arm 600 in the up and down directions. In some embodiments, the swing arm 600 includes an inclined end surface 62 that cooperates with the first connecting rod 41 , and the inclined end surface 62 is inclined from top to bottom in a direction that is continuously away from the driving mechanism 300 .By adopting the above scheme, during the process of the telescopic rod 30 of the driving mechanism 300 extending and driving the first pushing rod 40 to move, the first connecting rod 41 can give a force to the inclined end surface 62 of the swing arm 600 to make the swing arm 600 move upward, and under the action of the second limiting member 102, the movement of the swing arm 600 along the length direction of the first pushing rod 40 is limited, so that it moves upward relatively, thereby driving one end of the handle 200 to move upward relatively; at the same time, under the action of the second pushing rod 50, the other end of the handle 200 is driven to move upward synchronously, so that the handle 200 extends parallel to the opening 10 to the extended state. During this process, the second connecting rod 51 moves in the straight section 1011a of the limiting groove 1011 of the first limiting member 101; and the second connecting rod 50 of the second pushing rod 50 When 51 moves along the arc segment 1011b of the limiting groove 1011 of the first limiting member 101 and drives the handle 200 to continue to move, at this time, the first connecting rod 41 has been separated from the inclined end surface 62 and placed at the bottom end of the swing arm 600, then the swing arm 600 will not be driven to move, and the end of the handle 200 connected to the swing arm 600 will not be driven to move. If the end of the handle 200 connected to the second push rod 50 continues to move, an unlocked state with one end tilted up will be achieved; and in the process of the handle 200 moving from the extended state to the hidden state, the first connecting rod 41 moves from the bottom end of the swing arm 600 to under its inclined end surface 62, then the third torsion spring 103 is released, and under its action force, the swing arm 600 is driven to move downward, thereby pulling the handle 200 to move downward, so that the handle 200 moves downward synchronously to the hidden state.

[0079] In some embodiments, the swing arm 600 is provided with damping teeth 61 around the connection between the swing arm 600 and the handle 200, and the handle 200 is provided with a damping wheel 20 that can mesh with the damping teeth 61. On the one hand, by providing the damping wheel 20 and the damping teeth 61, it can be avoided that when the handle 200 is switched from the unlocked state to the extended state, the handle 200 is reset too quickly, causing the hand to be pinched. At the same time, the meshing transmission of the damping teeth 61 and the damping wheel 20 can improve the movement comfort. On the other hand, when the swing arm 600 is swinging, due to the meshing rotation of the damping wheel 20 and the damping teeth 61, the locking force is good, and then it will encounter resistance. This can not only prevent the swing arm 600 from colliding with other components due to excessive swinging speed, but also prevent the handle 200 from switching to the unlocked state due to the malfunction of the swing arm 600 during the shaking of the vehicle.

[0080] In some embodiments, an ambient light 900 is provided at the edge of the housing 100 near the opening 10. With the above solution, the ambient light 900 will automatically start at low brightness to provide lighting, help identify the operating area of ​​the handle 200, and enhance the user experience. In some embodiments, a heating wire 21 is also provided in the handle 200, and the heating wire 21 is arranged circumferentially along the inner wall of the edge of the handle 200; when in a low temperature environment in winter, the heating wire 21 can effectively heat the handle 200, thereby melting the ice that may be formed; it can prevent the handle 200 from being unable to open or suffering structural damage due to ice, and ensure the continuous and reliable operation of the product.
