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.

[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;

[0014] The second pushing mechanism and the swing arm can drive the handle to move out of the opening.

[0015] In some embodiments, the shell includes a first shell and a second shell which are arranged on the left and right and are detachably connected. After the first shell and the second shell are assembled, the bottom end thereof is a closed structure and the opening is formed at the top; and, after the first shell and the second shell are assembled, a receiving space for accommodating the driving mechanism, the first pushing mechanism, the second pushing mechanism, the swing arm, and the first reset mechanism 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 reciprocate in the length direction, thereby controlling the extension and retraction of the handle, and the degree of automation is high; the driving mechanism is clamped between the first shell and the second shell, which can ensure the stability of the driving mechanism during operation, and can ensure the stability of the operation of the first pushing mechanism, the second pushing mechanism and the swing arm, thereby ensuring the stability of the handle movement process and improving the sense of embodiment.

[0016] 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 will be 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; under the action of the first resetting mechanism, during the resetting process, a force can be applied to the second pushing mechanism to make it move in the direction close to the first pushing mechanism to achieve resetting.

[0017] In some embodiments, the first reset mechanism includes a first connecting rod rotatably connected to the shell, a second connecting rod hinged to the first connecting rod, and a first reset member that gives the first connecting rod a tendency to always move in the direction of the handle; wherein, the other end of the second connecting rod is rotatably connected to the second pushing mechanism, and the hinge between the first connecting rod and the second connecting rod is arranged close to one side of the first pushing mechanism.

[0018] In some embodiments, one end of the first connecting rod is rotatably connected to the shell through a rotating shaft, the first reset member is a torsion spring structure, and is sleeved on the rotating shaft, and one end is connected to the first connecting rod, and gives the first connecting rod a tendency to always move in a direction close to the handle; and in the process where the second pushing mechanism moves toward a side away from the first pushing mechanism under the action of the first pushing mechanism, the second pushing mechanism will drive the second connecting rod to move synchronously, and drive the first connecting rod and one end of the second connecting rod to move in a direction away from the handle, during which the first reset member stores energy; and when the handle needs to be reset, the first reset member will give the first connecting rod a rebound force to move in a direction close to the handle, thereby driving the second connecting rod to move, and driving the second pushing mechanism to move in a direction close to the first pushing mechanism, thereby achieving reset.

[0019] In some embodiments, the first connecting rod is relatively disposed above the second connecting rod.

[0020] In some embodiments, the shell is located above the first connecting rod and is provided with a first abutting portion that can abut against the first connecting rod to limit the movement of the first connecting rod, thereby preventing excessive movement and collision after driving the second pushing mechanism to move toward a side direction close to the first pushing mechanism, thereby ensuring the smoothness of the movement and the silent movement of the overall structure.

[0021] In some embodiments, the second pushing mechanism includes a second pushing rod, one end of which is connected to the first pushing mechanism, and the other end is rotatably connected to the handle; and a first limiting member is provided on two opposite side walls of the shell, and the first limiting member is provided with a limiting groove for limiting the movement trajectory of the second pushing rod, and the two ends of the second pushing rod are respectively adapted in the limiting groove and can move in the limiting groove; so that when the two ends of the second pushing rod move along the limiting groove, the handle will be driven to move up and down.

[0022] In some embodiments, the second push rod is in contact with and connected to the first push mechanism, and a buffer is provided on the first push mechanism, and the buffer is in contact with and connected to the second push rod; one end of the second push rod connected to the first push mechanism is provided with shaft portions at both ends thereof, and the shaft portions are adapted in the limiting groove and can move along the limiting groove; the second connecting rod is rotatably connected to the second push rod at a position between the two shaft portions.

[0023] 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 pushing 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 pushing 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.

[0024] By adopting the above scheme, when the shaft of the second push 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 shaft of the second push 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 shaft of the second push 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.

[0025] In some embodiments, a second reset mechanism is further disposed in the housing and is capable of giving the second push rod a tendency to move toward a direction close to the first push mechanism.

[0026] In some embodiments, the second reset mechanism includes a second reset member rotatably connected to the two side walls of the shell, the second reset member includes a rotating shaft, and an abutment portion formed by the rotating shaft extending outward from the outer wall of the limiting groove, the abutment portion extends into the limiting groove, and the straight section of the limiting groove is provided with a raised extension wall, which can abut against the abutment portion so that the abutment portion is placed in the arc segment of the limiting groove; and a second torsion spring is sleeved on the rotating shaft, one end of the second torsion spring abuts against the shell, and the other end abuts against the abutment portion, which can give the abutment portion a tendency to always move in a direction close to the straight section; then, in the process of the second push rod moving along the limiting groove, when the second push rod moves to the straight section and the arc segment, the shaft portion of the second push rod The second push rod abuts against the abutment portion, and as the second push rod continues to move along the arc segment, the shaft of the second push rod will give the abutment portion a force to make it move upward synchronously. In this process, the second torsion spring will store energy, and in the process of hiding the handle, the second torsion spring will give the abutment portion a force to move downward, and the first reset mechanism will synchronously drive the second push rod to move toward a side direction close to the first push mechanism, and then can give the second push rod a force to move from the arc segment to the straight line segment, and after the shaft of the second push rod moves into the straight line segment, the first reset mechanism will continue to drive the second push rod to move toward a side direction close to the first push mechanism, until the first connecting rod abuts against the first abutment portion, completing the reset.

[0027] In some embodiments, the shell is provided with a second abutment portion above the limiting groove; an open end is provided at one end of the arc segment away from the straight segment, and the size of the open end can allow the abutment portion to extend; to ensure that the shaft of the second push rod can abut against the end of the arc segment; and when the shaft of the second push rod moves to abut against the end of the arc segment, the abutment portion just abuts against the second abutment portion, and the double limitation makes the movement of the handle smoother.

[0028] 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.

[0029] 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; a second connecting rod is provided at one end of the two first pushing rods away from the driving mechanism, and a protruding pushing portion is provided at one end of the second connecting rod away from the first connecting rod, and the pushing portion abuts against the first pushing rod so that the movement of the first pushing rod can drive the movement of the second pushing rod, thereby pushing the handle When the first push rod is disengaged from the second push rod, the second push rod will be disengaged from the first reset mechanism and the second reset mechanism, thereby realizing that the raised end of the handle moves downward until both ends are flush with each other; the continued backward movement of the first push rod will cause its first connecting rod to be disengaged from the swing arm, and the swing arm will move downward synchronously under the action of the first torsion spring. At the same time, the second push rod will continue to move backward under the action of the second reset mechanism, so that the swing arm and the second push rod will drive the handle to move downward synchronously until it is flush with the opening to a hidden state.

[0030] 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.

[0031] 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; and a first torsion spring is provided at the rotational connection between the swing arm and the shell, one end of the first torsion spring is against the shell, and the other end is against the swing arm, which can give the swing arm a tendency to rotate downward.

[0032] In some embodiments, the second position limiting member is restricted between the first shell and the second shell to facilitate subsequent disassembly and assembly, and the second position limiting member includes two spaced-apart protrusions. Correspondingly, the swing arm is provided with two spaced-apart grooves to respectively adapt to the two protrusions, and the swing arm is provided with a pressing portion between the two grooves that can be pressed at a position between the two protrusions, which can improve the stability of the second position limiting member to a certain extent.

[0033] 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.

[0034] 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 give a force to 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 limited, so that it moves relatively upward, thereby driving one end of the handle to move relatively upward; 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 outlet in parallel to the extended state. In this process, the shaft portion of the second pushing rod moves within the straight line segment of the limiting groove of the first limiting member; and When the shaft 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 is placed at the bottom end of the swing arm, 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. The end of the handle connected to the second push rod continues to move, and an unlocked state with one end raised will be achieved; and in the process of the handle changing from the extended state to the hidden state, the first connecting rod moves from the bottom end of the swing arm to under its inclined end surface, and the first torsion spring is released, and under its action force, the swing arm is driven to move downward, thereby pulling the handle to move downward, so that the handle moves downward synchronously to the hidden state.

[0035] 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.

[0036] 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.

[0037] In some embodiments, two travel limit switches that can be connected to the travel limit member signal are arranged on the shell. In the process of the travel limit member moving with the first push rod, when the travel limit member approaches the first travel limit switch, the second push rod just moves to the connection between the arc segment and the straight segment, and the swing arm is pushed and lifted by the first push rod, so that the handle is lifted to the extended state; and when the travel limit member approaches the second travel limit switch, the second push rod just moves to the end of the arc segment away from the straight segment, so that one end of the handle is tilted to the unlocked state to unlock the lock cylinder; this process accurately detects the travel stroke, and then accurately controls the movement state of the handle, with a high degree of automation; the travel limit member is fixed to the side wall of the first push rod by screws so as to better connect with the travel limit switch signal.

[0038] By adopting the above scheme, the movement stroke of the first push rod can be controlled separately by setting the movement stroke of the stroke limiter, and the movement stroke of the second push rod and the swing arm can be controlled, thereby controlling the movement state of the handle; when the driving mechanism drives the first push rod 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 to the extended state; when the driving mechanism drives the first push rod 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 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, during the reverse movement, the return of the handle can also be accurately controlled.

[0039] In some embodiments, an ambient light is provided at the edge of the shell near the opening; the ambient light will automatically start at low brightness to provide lighting, help identify the handle operation area, and enhance the user experience.

[0040] 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.

[0041] 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.

[0042] The solution adopted by the utility model to solve the above technical problem is a vehicle, which is characterized by comprising the door handle structure as mentioned above.

[0043] (III) Beneficial effects

[0044] Compared with the prior art, the utility model designs a door handle structure and a vehicle.

[0045] (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;

[0046] (2) Under the action of the first reset mechanism, the utility model can provide a force to the second pushing mechanism during the reset process, causing it to move in a direction close to the first pushing mechanism, so as to achieve reset;

[0047] (3) 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 mesh and rotate, 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 switching to the unlocked state due to the erroneous movement of the swing arm during the shaking of the vehicle.

[0048] (4) The utility model is provided with an ambient light at the edge of the housing near the opening; the ambient light will automatically start at low brightness to provide lighting, help identify the handle operation area, and enhance the user experience;

[0049] (5) The utility model has a heating wire in the handle. When in a low temperature environment in winter, the heating wire can effectively heat the handle, thereby melting any ice that may have formed. This can prevent the handle from being unable to open due to ice or from suffering structural damage, thereby ensuring the continued reliable operation of the product.

In some embodiments, the second push rod 50 is in contact with and connected to the first push mechanism 400, and a buffer member 41 is provided on the first push mechanism 400, and the buffer member 41 is in contact with and connected to the second push rod 50; one end of the second push rod 50 connected to the first push mechanism 400 is provided with an axis 501 at both ends thereof, and the axis 501 is adapted in the limiting groove 110 and can move along the limiting groove 110; the second connecting rod 61 is rotatably connected to the second push rod 50 at a position between the two axis portions 501. In some embodiments, the limiting groove 110 includes a straight segment 110a and an arc segment 110b; the straight segment 110a is arranged close to the first pushing mechanism 400; when the second pushing rod 50 moves in the straight segment 110a, 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 pushing rod 50 moves in the arc segment 110b, 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 shaft portion 501 of the second push rod 50 abuts against the side of the straight segment 110a away from the arc segment 110b, the handle 200 is in a hidden state flush with the opening 10; when the shaft portion 501 of the second push rod 50 moves to the connection between the straight segment 110a and the arc segment 110b, the handle 200 is in an extended state parallel to the opening 10; when the shaft portion 501 of the second push rod 50 moves to the point where it abuts against the side of the arc segment 110b away from the straight segment 110a, 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.

[0076] In some embodiments, the housing 100 is further provided with a second reset mechanism 800 capable of giving the second push rod 50 a tendency to move toward a direction close to the first push mechanism 400.

As the second push rod 50 continues to move along the arc segment 110b, the shaft portion 501 of the second push rod 50 will give the abutment portion 802 a force to make it move upward synchronously. In this process, the second torsion spring 81 will store energy, and in the process of hiding the handle 200, the second torsion spring 81 will give the abutment portion 802 a force to move downward. The first reset mechanism 600 will synchronously drive the second push rod 50 to move toward a side direction close to the first push mechanism 400, and then can give the second push rod 50 a force to move from the arc segment 110b to the straight segment 110a. After the shaft portion 501 of the second push rod 50 moves into the straight segment 110a, the first reset mechanism 600 will continue to drive the second push rod 50 to move toward a side direction close to the first push mechanism 400 until the first connecting rod 60 abuts against the first abutment portion 14 to complete the reset.In some embodiments, the shell 100 is provided with a second abutment portion 15 above the limiting groove 110; the arc segment 110b is provided with an open end 110d at one end away from the straight segment 110a, and the size of the open end 110d can allow the abutment portion 802 to extend; to ensure that the shaft portion 501 of the second push rod 50 can abut against the end of the arc segment 110b; and when the shaft portion 501 of the second push rod 50 moves to abut against the end of the arc segment 110b, the abutment portion 802 just abuts against the second abutment portion 15, and the double limitation makes the movement of the handle 200 smoother.

[0077] In some embodiments, the first pushing mechanism 400 includes two first pushing rods 40 arranged at intervals, and the swing arm 700 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 700 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 42 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 42, so that the telescopic movement of the driving mechanism 300 can drive the linear reciprocating movement of the first pushing rod 40; a second connecting rod 43 is provided at one end of the two first pushing rods 40 away from the driving mechanism 300, and a protruding pushing portion 44 is provided at one end of the second connecting rod away from the first connecting rod 42, and the pushing portion 44 abuts against the first pushing rod 40, so that the movement of the first pushing rod 40 can drive the movement of the second pushing rod 50, thereby pushing the handle 200 out of the handle 200. Opening 10; and when the telescopic rod 30 of the driving mechanism 300 drives the first pushing rod 40 to move back to its original position, the first pushing rod 40 disengages from the second pushing rod 50, and the second pushing rod 50 moves back to its original position under the action of the first reset mechanism 600 and the second reset mechanism 800, thereby realizing that the raised end of the handle 200 moves downward until both ends are flush; then the continued backward movement of the first pushing rod 40 causes its first connecting rod 42 to disengage from the swing arm 700, and the swing arm 700 moves downward synchronously under the action of the first torsion spring 74, and at the same time, the second pushing rod 50 continues to move backward under the action of the second reset mechanism 800, so that the swing arm 700 and the second pushing rod 50 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 42 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 is higher than the height of the third section 403 relative to the bottom cover, so that the first section 401 is closer to the handle 200 and the first connecting rod 42 is closer to the swing arm 700. In the process of the driving mechanism 300 extending to drive the first push rod 40 to move, the first connecting rod 42 can give the swing arm 700 a force to make it move.

[0078] In some embodiments, a second limit member 900 for limiting the movement trajectory of the swing arm 700 is provided at one end of the shell 100 away from the opening 10; the swing arm 700 is provided with a slot 70, and the second limit member 900 is vertically adapted in the slot 70, so that the second limit member 900 can limit the movement of the swing arm 700 in the up and down directions; and a first torsion spring 74 is provided at the rotational connection between the swing arm 700 and the shell 100, one end of the first torsion spring 74 is against the shell 100, and the other end is against the swing arm 700, which can give the swing arm 700 a tendency to rotate downward. In some embodiments, the second limit member 900 is restricted between the first shell 12 and the second shell 13 to facilitate subsequent disassembly and assembly, and the second limit member 900 includes two spaced-apart protrusions 91. Correspondingly, the swing arm 700 is provided with two spaced-apart grooves 70 to respectively adapt to the two protrusions 91, and the swing arm 700 is provided with a pressing portion 71 located between the two grooves 70 and capable of pressing at a position between the two protrusions 91, which can improve the stability of the second limit member 900 to a certain extent.

[0079] In some embodiments, the swing arm 700 includes an inclined end surface 72 that cooperates with the first connecting rod 42, and the inclined end surface 72 is inclined from top to bottom in a direction that is constantly away from the driving mechanism 300. With the above solution, during the process of the telescopic rod 30 of the driving mechanism 300 extending and driving the first push rod 40 to move, the first connecting rod 42 can give the inclined end surface 72 of the swing arm 700 a force to make the swing arm 700 move upward, and under the action of the second limiting member 900, the movement of the swing arm 700 along the length direction of the first push 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 can be extended parallel to the outlet to the extended state. In this process, the shaft portion 501 of the second pushing rod 50 moves along the straight section 110a of the limiting groove 110 of the first limiting member 11; and at the shaft portion 501 of the second pushing rod 50, the shaft portion 502 of the second pushing rod 50 moves along the straight section 110a of the limiting groove 110 of the first limiting member 11; and at the shaft portion 502 of the second pushing rod 50, the shaft portion 503 of the second pushing rod 50 moves along the straight section 110a of the limiting groove 110 of the first limiting member 11; and at the shaft portion 501 of the second pushing rod 50, the shaft portion 502 ... When 501 moves along the arc segment 110b of the limiting groove 110 of the first limiting member 11 and drives the handle 200 to continue to move, at this time, the first connecting rod 42 has been separated from the inclined end surface 72 and placed at the bottom end of the swing arm 700, then the swing arm 700 will not be driven to move, and the end of the handle 200 connected to the swing arm 700 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 changing from the extended state to the hidden state, the first connecting rod 42 moves from the bottom end of the swing arm 700 to under its inclined end surface 72, then the first torsion spring 74 is released, and under its action force, the swing arm 700 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.

[0080] In some embodiments, the swing arm 700 is provided with damping teeth 73 around the connection between the swing arm 700 and the handle 200, and the handle 200 is provided with a damping wheel 20 that can mesh with the damping teeth 73. On the one hand, by providing the damping wheel 20 and the damping teeth 73, 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 73 and the damping wheel 20 can improve the movement comfort. On the other hand, when the swing arm 700 is swinging, due to the meshing rotation of the damping wheel 20 and the damping teeth 73, the locking force is good, and then it will encounter resistance. This can not only prevent the swing arm 700 from colliding with other components due to the excessively fast swinging speed, but also prevent the handle 200 from switching to the unlocked state due to the malfunction of the swing arm 700 during the shaking of the vehicle.

[0081] In some embodiments, a stroke limiter 101 is connected to the first pushing mechanism 400, and the stroke limiter 101 can limit the moving stroke of the first pushing mechanism 400 to control the movement state of the handle 200. In some embodiments, two stroke limit switches 102 that can be connected to the stroke limiter 101 by signal are also arranged on the housing 100. When the stroke limiter 101 moves along with the first pushing rod 40, when the stroke limiter 101 approaches the first stroke limiter 102, the second pushing rod 50 just moves to the connection between the arc segment 110b and the straight segment 110a, and the swing arm 700 is pushed up by the first pushing rod 40, so that the handle 200 is lifted out to the extended state; and in the When the travel limit member 101 approaches the second travel limit switch 102, the second push rod 50 just moves to the end of the arc segment 110b away from the straight segment 110a, so that one end of the handle 200 is tilted to the unlocked state to unlock the lock cylinder; this process accurately detects the travel stroke, and then accurately controls the movement state of the handle 200, with a high degree of automation; the travel limit member 101 is fixed to the side wall of the first push rod 40 by screws, so as to better connect the signal with the travel limit switch 102. By adopting the above scheme, the movement stroke of the first push rod 40 can be controlled respectively by setting the movement stroke of the stroke limiter 101, and the movement stroke of the second push rod 50 and the swing arm 700 can be controlled, thereby controlling the movement state of the handle 200; when the driving mechanism 300 drives the first push rod 40 to move to the first stroke, the stroke limiter 101 will give a signal to the controller, at this time, the handle 200 is driven to extend parallel to the opening 10 to the extended state; when the driving mechanism 300 drives the first push rod 40 to move to the second stroke, the stroke limiter 101 will give a signal to the controller, at this time, the handle 200 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 200; at the same time, during the reverse movement, the return of the handle 200 can also be accurately controlled.

[0082] In some embodiments, an ambient light is provided at the edge of the housing 100 near the opening 10; the ambient light automatically starts 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 is also provided inside the handle 200, and the heating wire 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 can effectively heat the handle 200, thereby melting any ice that may form; this can prevent the handle 200 from being unable to be opened or suffering structural damage due to ice, thereby ensuring the continued reliable operation of the product.

[0083] The same and similar parts between the various embodiments in this specification can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0084] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
