Description

Technical Field

[0001] This utility model relates to the technical field of door handles, and more particularly to a door handle for automobiles. Background Technology

[0002] With the rapid development of the automotive industry and the increasing demands of consumers for automotive safety and convenience, automotive door lock systems have gradually evolved from traditional purely mechanical locks to intelligent door lock systems that integrate electronic control functions.

[0003] Existing door handles primarily rely on visual indicator lights or audible cues to indicate the locking status, but lack intuitive tactile feedback. In real-world driving environments, drivers often cannot promptly notice visual or auditory signals and require more direct tactile feedback to confirm the operational status. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem this invention aims to solve is to provide a door handle for automobiles that forms a precise linkage between the operating handle, slider, linkage, and micro switch, ensuring that the micro switch is triggered precisely at a specific moving distance A, thus achieving precise synchronization between mechanical action and electronic control. Simultaneously, the preset moving distance A allows for precise control of the triggering timing, avoiding false triggering or delayed triggering. Furthermore, the contact design between the slider and linkage provides clear triggering feedback to the user, improving the operating feel.

[0006] (II) Technical Solution

[0007] The solution adopted by this utility model to solve the above-mentioned technical problem is a car door handle, including...

[0008] Base;

[0009] An operating handle, which is rotatably mounted on the base, is used to receive external operating force;

[0010] A micro switch, fixed on the base, is used to control the opening and closing of the electronic lock, and the micro switch can be triggered when the operating handle is rotated;

[0011] The slider moves synchronously with the operating handle;

[0012] A connecting rod is disposed on the movement path of the slider;

[0013] When the operating handle is rotated and the slider is moved a distance A, the slider contacts the connecting rod, the micro switch is triggered, and the electronic lock is unlocked.

[0014] In some embodiments, the moving distance A is 4 mm.

[0015] In some embodiments, a rotating shaft is provided on the base, and the operating handle is connected to the base through the rotating shaft. The operating handle is rotatable around the central axis of the rotating shaft. Furthermore, a reset member for driving the operating handle to reset is sleeved on the rotating shaft.

[0016] In some embodiments, the reset member includes a second elastic member, one end of which abuts against the base and the other end against the operating handle, so that the second elastic member can give the operating handle a tendency to rotate in the reset direction.

[0017] Specifically, the second elastic element is a torsion spring.

[0018] In some embodiments, the operating handle includes a rotating seat rotatably connected to the base and a handle extending from one end of the rotating seat; the base includes a receiving groove for receiving the operating handle; the receiving groove includes a first receiving groove for receiving the rotating seat and a second receiving groove for receiving the handle; and the bottom of the first receiving groove is through-hole so that the rotating seat can be avoided after the operating handle is rotated; the top of the rotating seat extends upward near the two side walls of the base to form two rotating arms, and the rotating shaft is connected between the two rotating arms; the bottom portion of the rotating seat extends downward to form a trigger wall for triggering the micro switch.

[0019] In some embodiments, the connection between the rotating seat and the handle is provided with a first engaging groove for engaging one end of the second elastic member; the base is provided with a second engaging groove for engaging the other end of the second elastic member at the end of the rotating seat away from the handle.

[0020] By adopting the above scheme, a precise linkage is formed between the operating handle, slider, linkage, and micro switch, ensuring that the micro switch is triggered precisely at a specific movement distance A, thus achieving precise synchronization between mechanical action and electronic control. The preset movement distance A allows for precise control of the triggering timing, avoiding problems such as false triggering or untimely triggering. The contact design between the slider and linkage provides clear triggering feedback to the user, improving the operating feel. The 4mm movement distance design is short enough to prevent excessive force from the user, and long enough to prevent false triggering (such as when the vehicle is bumpy).

[0021] In some embodiments, a sudden force can be generated when the slider travels a distance A and contacts the connecting rod to indicate to the customer that the electronic lock has been unlocked.

[0022] Using the above scheme, when the slider moves to a distance A, it makes rigid contact with the connecting rod. The mechanical resistance generated at the moment of contact forms a sudden change in force. The user can clearly feel the change in resistance through hand feel, which prevents the user from continuing to apply excessive force and prevents damage to the mechanism due to excessive operation. It provides the user with a clear indication of the operating boundary. At the same time, the sudden force only appears at the correct unlocking position (4mm), which prevents the user from releasing the handle halfway and causing unlocking failure.

[0023] In some embodiments, the slider includes a first contact surface disposed toward the connecting rod, and the connecting rod includes a second contact surface disposed toward the slider; when the slider moves a distance A, the first contact surface and the second contact surface come into contact with each other to generate mechanical resistance to form a sudden force.

[0024] Using the above solution, resistance is naturally generated by the collision of the first and second contact surfaces, without the need for additional sensors or electronic feedback modules.

[0025] In some embodiments, the connecting rod is rotatably disposed on the base, and the connecting rod includes a contact portion disposed on the movement path of the slider that can contact the slider.

[0026] Specifically, the contact portion is provided with a second contact surface.

[0027] In some embodiments, a first elastic element is provided between the connecting rod and the base, the first elastic element being able to provide a restoring force to reset the slider to its initial position after the operating handle is released.

[0028] In some embodiments, the base is further provided with a limiting portion for limiting the rotation angle of the connecting rod under the action of the first elastic member.

[0029] Specifically, the first elastic element includes a torsion spring, and one end of the first elastic element abuts against the end of the connecting rod away from the slider, and the other end abuts against the base, and can give the slider a tendency to always move in the reset direction.

[0030] Using the above scheme, the connecting rod can be rotatably fixed on the base. The contact part rotates after being pushed by the slider. When it is out of contact, it is reset by the first elastic element. The reset of the operating handle relies on the second elastic element. The reset of the connecting rod relies on the first elastic element. The independent reset of the connecting rod avoids jamming with the slider and ensures that the system returns to its initial state after each operation.

[0031] In some embodiments, the base is provided with a guide portion, which is used to limit the movement direction of the slider to ensure that the slider and the connecting rod can make accurate contact.

[0032] In some embodiments, the guide portion includes a guide groove disposed along the moving direction of the slider, the slider includes a sliding portion that slides in cooperation with the guide groove, and a mating portion extending from one end of the sliding portion near the connecting rod, wherein the mating portion contacts the connecting rod when the slider moves a distance A.

[0033] Specifically, the mating part is provided with the first contact surface.

[0034] By adopting the above scheme, the design of the guide groove can restrict the slider to move only in a straight line, ensuring precise alignment with the contact surface of the connecting rod.

[0035] In some embodiments, a damper is also included, which is disposed on the movement path of the operating handle and is capable of controlling the movement speed of the operating handle.

[0036] In some embodiments, the operating handle is provided with a first gear portion, and the damper includes a second gear portion capable of meshing with the first gear portion; and, through the meshing of the first gear portion and the second gear portion, the resistance of the damper is uniformly transmitted to the operating handle, thereby achieving more precise speed control.

[0037] In some embodiments, the second gear part is a circular gear structure, and the first gear part is an arc-shaped gear structure; through the combined design of the arc-shaped gear structure (first gear part) and the circular gear structure (second gear part), the rotation path of the operating handle is adapted to ensure that the damping effect is effective throughout the entire process.

[0038] In some embodiments, the damper is fixed to the base, and the end of the damper facing the operating handle is provided with the second gear portion; the damper is fixed to the base, and the second gear portion directly meshes with the operating handle, simplifying the assembly process and improving structural stability; the damper is arranged facing the operating handle, saving internal space and suitable for compact automotive interior layouts.

[0039] In some embodiments, the base is provided with a mounting groove for mounting the damper, the mounting groove is provided with a through hole penetrating the base, the second gear part can extend into the through hole and mesh with the first gear part, the inner wall of the through hole is also provided with a rib; and, the mounting groove is provided with fixing posts for fixing the damper at both ends of the through hole.

[0040] With the above solution, the arc-shaped gear (first gear part) of the operating handle meshes with the circular gear (second gear part) of the damper, generating uniform resistance during rotation and preventing the operating handle from quickly springing back.

[0041] In some embodiments, a buffer pin is also included, which is disposed between the base and the operating handle to buffer the impact force generated after the operating handle is reset by force.

[0042] In some embodiments, the buffer pin is fixed to the base, and the buffer surface of the buffer pin is disposed near the side where the operating handle is connected to the rotating shaft.

[0043] In some embodiments, the buffer pin is disposed on the base near the micro switch; the rotating seat is provided with an abutting surface near the trigger wall that can abut against the buffer pin.

[0044] With the above solution, the buffer pin is close to the micro switch and the trigger wall, specifically buffering the high impact area. The contact surface of the rotating seat contacts the buffer pin, absorbing the reset kinetic energy and preventing the operating handle from hitting the base and causing abnormal noise or structural damage when resetting. This also reduces the instantaneous impact force of the trigger wall on the micro switch.

[0045] In some embodiments, a zipper mechanism is further included, which is connected to the operating handle for controlling the opening and closing of the mechanical lock, and the operating handle can drive the zipper mechanism to move to unlock the mechanical lock when rotated.

[0046] In some embodiments, the zipper mechanism includes a pull cable, one end of which is connected to the operating handle and the other end to the mechanical lock, so that the zipper mechanism can move synchronously with the operating handle; and the mechanical lock is unlocked when the operating handle is rotated and the pull cable is moved 12mm; the base is also provided with a pull cable holder for the pull cable to pass through, which guides and constrains the movement of the pull cable, so that the rotation of the operating handle drives the movement of the pull cable more smoothly; the guiding design of the pull cable holder ensures smooth movement of the pull cable, avoids jamming or wear, and improves the stability of unlocking the mechanical lock.

[0047] Using the above solution, the electronic lock serves as the primary unlocking method with a fast response speed; the mechanical lock serves as a backup unlocking method and can still function normally in the event of an electronic system failure; the two systems are independent of each other, avoiding a single point of failure that would prevent the door from being opened completely, and complying with the redundancy requirements of automotive safety regulations for door lock systems.

[0048] (III) Beneficial Effects

[0049] Compared with the existing technology, this utility model designs a door handle for automobiles.

[0050] (1) This utility model forms a precise linkage relationship through the operating handle, slider, connecting rod and micro switch, ensuring that the micro switch is triggered exactly at a specific moving distance A, thus realizing precise synchronization between mechanical action and electronic control; at the same time, the triggering time can be precisely controlled by the preset moving distance A, avoiding the problem of false triggering or untimely triggering; and the contact design between the slider and the connecting rod can provide clear triggering feedback to the user, improving the operating feel.

[0051] (2) The 4mm moving distance of this utility model is short enough to avoid excessive force by the user, and long enough to avoid accidental triggering (such as when the vehicle is bumpy).

[0052] (3) When the slider moves to a distance A, it makes rigid contact with the connecting rod. The mechanical resistance generated at the moment of contact forms a sudden change in force. The user can clearly feel the change in resistance by hand, which prevents the user from continuing to apply excessive force and prevents damage to the mechanism due to excessive operation. It provides the user with a clear indication of the operation boundary. At the same time, the sudden force only appears at the correct unlocking position (4mm), which prevents the user from releasing the hand halfway and causing unlocking failure.

[0053] (4) The arc-shaped gear (first gear part) of the operating handle of this utility model meshes with the circular gear (second gear part) of the damper, generating uniform resistance when rotating, thus preventing the operating handle from quickly springing back;

[0054] (5) The buffer pin of this utility model is close to the micro switch and the trigger wall, and specifically buffers the high impact area. The contact surface of the rotating seat contacts the buffer pin, absorbs the reset kinetic energy, avoids the abnormal noise or structural damage caused by the impact of the operating handle on the base when it is reset, and reduces the instantaneous impact force of the trigger wall on the micro switch.

[0055] (6) The electronic lock of this utility model is the main unlocking method and has a fast response speed; the mechanical lock is the backup unlocking method and can still work normally when the electronic system fails; the two systems are independent of each other, avoiding a single point of failure that would make it impossible to open the door, which meets the redundancy requirements of automotive safety regulations for door lock systems.

[0074] like Figures 1-9 As shown, this utility model provides a car door unlocking handle, including a base 100; an operating handle 200, rotatably mounted on the base 100 for receiving external operating force; a micro switch 300 fixed on the base 100 for controlling the opening and closing of an electronic lock, and the micro switch 300 is triggered when the operating handle 200 is rotated; a slider 400 that moves synchronously with the operating handle 200; and a connecting rod 500 disposed on the movement path of the slider 400. When the operating handle 200 rotates and drives the slider 400 to move a distance A, the slider 400 contacts the connecting rod 500, and the micro switch 300 is triggered, unlocking the electronic lock. In some embodiments, the moving distance A is 4 mm. By adopting the above scheme, a precise linkage is formed between the operating handle 200, slider 400, connecting rod 500, and micro switch 300, ensuring that the micro switch 300 is triggered precisely at a specific moving distance A, thus achieving precise synchronization between mechanical action and electronic control. The preset moving distance A allows for precise control of the triggering timing, avoiding false triggering or delayed triggering. The contact design between the slider 400 and connecting rod 500 provides clear triggering feedback to the user, improving the operating feel. The 4mm moving distance design is short enough to prevent excessive force from the user, and long enough to prevent false triggering (such as when the vehicle is bumpy).

[0075] In some embodiments, a rotating shaft 102 is provided on the base 100, and the operating handle 200 is connected to the base 100 via the rotating shaft 102. The operating handle 200 is rotatable about the central axis of the rotating shaft 102. Furthermore, a reset member for resetting the operating handle 200 is sleeved on the rotating shaft 102. In some embodiments, the reset member includes a second elastic member 103, one end of which abuts against the base 100, and the other end abuts against the operating handle 200, so that the second elastic member 103 provides the operating handle 200 with a tendency to rotate in the reset direction. Specifically, the second elastic member 103 is a torsion spring. In some embodiments, the operating handle 200 includes a rotating seat 201 rotatably connected to the base 100 and a handle 202 extending from one end of the rotating seat 201; the base 100 includes a receiving groove 104 for receiving the operating handle 200; the receiving groove 104 includes a first receiving groove 1041 for receiving the rotating seat 201 and a second receiving groove 1042 for receiving the handle 202; and the bottom of the first receiving groove 1041 is through-hole so that the rotating seat 201 can be avoided after the operating handle 200 is rotated; the top of the rotating seat 201 extends upward near the two side walls of the base 100 to form two rotating arms 2011, and the rotating shaft 102 is connected between the two rotating arms 2011; the bottom portion of the rotating seat 201 extends downward to form a trigger wall 2012 for triggering the micro switch 300. In some embodiments, the connection between the rotating seat 201 and the handle 202 is provided with a first engaging groove 203 for engaging one end of the second elastic member 103; the base 100 is provided with a second engaging groove 105 for engaging the other end of the second elastic member 103 at the end of the rotating seat 201 away from the handle 202.

[0076] In some embodiments, a sudden force is generated when the slider 400 moves a distance A and contacts the connecting rod 500 to indicate to the customer that the electronic lock has been unlocked. Using this scheme, when the slider 400 moves to distance A, it makes rigid contact with the connecting rod 500. The mechanical resistance generated at the moment of contact forms a sudden change in force, which the user can clearly feel through touch, preventing the user from applying excessive force and avoiding damage to the mechanism due to over-operation. This provides the user with a clear indication of the operating boundary. Simultaneously, the sudden force only appears at the correct unlocking position (4mm), preventing the user from releasing the lever halfway and causing unlocking failure. In some embodiments, the slider 400 includes a first contact surface 401 facing the connecting rod 500, and the connecting rod 500 includes a second contact surface 501 facing the slider 400. When the slider 400 moves a distance A, the first contact surface 401 and the second contact surface 501 contact each other, generating mechanical resistance to form a sudden force. Using this scheme, resistance is naturally generated by the collision of the first contact surface 401 and the second contact surface 501, without the need for additional sensors or electronic feedback modules. In some embodiments, the connecting rod 500 is rotatably mounted on the base 100, and the connecting rod 500 includes a contact portion 502 disposed on the movement path of the slider 400 and capable of contacting the slider 400. Specifically, the contact portion 502 is provided with a second contact surface 501. In some embodiments, a first elastic member 600 is disposed between the connecting rod 500 and the base 100, and the first elastic member 600 can provide a restoring force to reset the slider 400 to its initial position after the operating handle 200 is released. In some embodiments, the base 100 is further provided with a limiting portion 108 for limiting the rotation angle of the connecting rod 500 under the action of the first elastic member 600. Specifically, the first elastic member 600 includes a torsion spring, and one end of the first elastic member 600 abuts against the end of the connecting rod 500 away from the slider 400, and the other end abuts against the base 100, and can give the slider 400 a tendency to always move in the reset direction. Using the above scheme, the connecting rod 500 is rotatably fixed on the base 100. The contact part 502 rotates after being pushed by the slider 400. When it is disengaged, it is reset by the first elastic element 600. The reset of the operating handle 200 is achieved by the second elastic element 103. The reset of the connecting rod 500 is achieved by the first elastic element 600. The independent reset of the connecting rod 500 avoids jamming with the slider 400, ensuring that the system returns to its initial state after each operation.

[0077] In some embodiments, the base 100 is provided with a guide portion 101, which is used to limit the movement direction of the slider 400 to ensure that the slider 400 can accurately contact the connecting rod 500. In some embodiments, the guide portion 101 includes a guide groove 1011 provided along the movement direction of the slider 400, and the slider 400 includes a sliding portion 402 that slides in cooperation with the guide groove 1011, and a mating portion 403 extending from one end of the sliding portion 402 near the connecting rod 500. When the slider 400 moves a distance A, the mating portion 403 contacts the connecting rod 500. Specifically, the mating portion 403 is provided with a first contact surface 401. By adopting the above solution, the design of the guide groove 1011 can limit the slider 400 to move only in a straight line, ensuring precise alignment with the contact surface of the connecting rod 500.

[0078] In some embodiments, a damper 700 is further included, which is disposed on the movement path of the operating handle 200 and can control the movement speed of the operating handle 200. In some embodiments, the operating handle 200 is provided with a first gear portion 204, and the damper 700 includes a second gear portion 701 capable of meshing with the first gear portion 204; and, through the meshing of the first gear portion 204 and the second gear portion 701, the resistance of the damper 700 is uniformly transmitted to the operating handle 200, achieving more precise speed control. In some embodiments, the second gear portion 701 is a circular gear structure, and the first gear portion 204 is an arc-shaped gear structure; through the combined design of the arc-shaped gear structure (first gear portion 204) and the circular gear structure (second gear portion 701), the rotation path of the operating handle 200 is adapted to ensure that the damping effect is effective throughout the entire process. In some embodiments, the damper 700 is fixed to the base 100, and a second gear portion 701 is provided at one end of the damper 700 facing the operating handle 200. The damper 700 is fixed to the base 100, and the second gear portion 701 directly meshes with the operating handle 200, simplifying the assembly process and improving structural stability. The damper 700 is arranged facing the operating handle 200, saving internal space and suitable for compact automotive interior layouts. In some embodiments, the base 100 is provided with a mounting groove 106 for mounting the damper 700. The mounting groove 106 is provided with a through hole 1061 penetrating the base 100. The second gear portion 701 can extend into the through hole 1061 and mesh with the first gear portion 204. The inner wall of the through hole 1061 is also provided with a rib. Furthermore, the mounting groove 106 is provided with fixing posts 1062 for fixing the damper 700 at both ends of the through hole 1061. With the above solution, the arc-shaped gear (first gear part 204) of the operating handle 200 meshes with the circular gear (second gear part 701) of the damper 700, generating uniform resistance when rotating, thus preventing the operating handle 200 from quickly springing back.

[0079] In some embodiments, a buffer pin 800 is further included, which is disposed between the base 100 and the operating handle 200 to buffer the impact force generated after the operating handle 200 is forced to reset. In some embodiments, the buffer pin 800 is fixed on the base 100, and the buffer surface 801 of the buffer pin 800 is disposed near the side where the operating handle 200 is connected to the rotating shaft 102. In some embodiments, the buffer pin 800 is disposed on the base 100 near the micro switch 300; the rotating seat 201 is provided with an abutment surface 2013 near the trigger wall 2012 that can abut against the buffer pin 800. With the above solution, the buffer pin 800 is close to the micro switch 300 and the trigger wall 2012, specifically buffering the high impact area. The contact surface 2013 of the rotating seat 201 contacts the buffer pin 800 to absorb the reset kinetic energy, avoiding abnormal noise or structural damage caused by the operating handle 200 hitting the base 100 when resetting, and reducing the instantaneous impact force of the trigger wall 2012 on the micro switch 300.

[0080] In some embodiments, a zipper mechanism 900 is further included, which is connected to the operating handle 200 for controlling the opening and closing of the mechanical lock. When the operating handle 200 is rotated, it can drive the zipper mechanism 900 to move and unlock the mechanical lock. In some embodiments, the zipper mechanism 900 includes a pull cable 901, one end of which is connected to the operating handle 200, and the other end is connected to the mechanical lock, so that the zipper mechanism 900 can move synchronously with the operating handle 200. The mechanical lock is unlocked when the operating handle 200 rotates and moves the pull cable 901 12mm. The base 100 is also provided with a pull cable holder 107 for the pull cable 901 to pass through, for guiding and constraining the movement of the pull cable 901, so that the rotation of the operating handle 200 drives the movement of the pull cable 901 more smoothly. The guiding design of the pull cable holder 107 ensures smooth movement of the pull cable 901, avoids jamming or wear, and improves the stability of unlocking the mechanical lock. Using the above solution, the electronic lock serves as the primary unlocking method with a fast response speed; the mechanical lock serves as a backup unlocking method and can still function normally in the event of an electronic system failure; the two systems are independent of each other, avoiding a single point of failure that would prevent the door from being opened completely, and complying with the redundancy requirements of automotive safety regulations for door lock systems.
