Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem this utility model aims to solve is to provide an internal unlocking handle for automobiles. By integrating a micro switch (electronic lock control) and a zipper mechanism (mechanical lock control) onto the same operating handle, it significantly reduces costs. It achieves coordinated operation of electronic and mechanical dual unlocking modes, greatly improving safety performance. Even if the electronic system fails, the mechanical lock can still work normally, enhancing user convenience and system reliability. By controlling the movement speed of the operating handle through a damper, it avoids noise caused by rapid rebound or impact, improving the operating feel and component lifespan. It provides both dual safety protection and an improved user experience.

[0006] (II) Technical Solution

[0007] The solution adopted by this utility model to solve the above-mentioned technical problem is an inward-opening latch for automobiles, including...

[0008] Base;

[0009] An operating handle is rotatably connected to the base;

[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] A zipper mechanism is connected to the operating handle and is used to control the opening and closing of the mechanical lock. When the operating handle is rotated, it can drive the zipper mechanism to move to unlock the mechanical lock.

[0012] A damper, which is disposed on the movement path of the operating handle, is capable of controlling the movement speed of the operating handle.

[0013] In some embodiments, the pull-lock mechanism includes a pull cable, one end of which is connected to the operating handle and the other end to a mechanical lock; so that the mechanical lock can be unlocked when the operating handle is rotated to 40°; the pull cable is fixed to the operating handle by a fixing block, the fixing block including a fixing head for fixing the pull cable, the fixing head including two elastic locking parts, the operating handle including a mounting hole for adapting to the elastic locking parts, the elastic locking parts including a groove that can engage with the wall of the mounting hole, so as to realize the fixed installation of the pull cable on the operating handle. The system is designed to allow the operating handle to rotate, thereby driving the movement of the pull cable to unlock the mechanical lock. The base also features a pull cable holder for the pull cable to pass through, guiding and constraining its movement to ensure smoother operation. The guide design of the pull cable holder ensures smooth cable movement, preventing jamming or wear and improving the stability of the mechanical lock unlocking process. The elastic locking part of the fixing block engages with the mounting hole for quick installation, reducing assembly complexity. The mechanical lock unlocks when the operating handle is rotated to 40°, providing clear mechanical feedback and conforming to ergonomic principles.

[0014] By integrating the micro switch (electronic lock control) and the zipper mechanism (mechanical lock control) onto the same operating handle, the cost is greatly reduced; the coordinated operation of electronic and mechanical dual unlocking modes is realized, greatly improving the safety performance. Even if the electronic system fails, the mechanical lock can still work normally, improving user operation convenience and system reliability; the movement speed of the operating handle is controlled by a damper to avoid noise caused by rapid rebound or impact, improving the operating feel and component life.

[0015] 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.

[0016] 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.

[0017] By adopting the above scheme, the resistance of the damper is evenly transmitted to the operating handle through the meshing of the first gear and the second gear, thereby achieving more precise speed control.

[0018] 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.

[0019] With the above solution, the damper is fixed to the base, and the second gear directly meshes with the operating handle, simplifying the assembly process and improving structural stability; the damper is arranged towards the operating handle, saving internal space and making it suitable for compact automotive interior layouts.

[0020] 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; and, the mounting groove is provided with fixing posts for fixing the damper at both ends of the through hole.

[0021] In some embodiments, the base has a receiving groove for receiving the operating handle, the sidewall of the receiving groove is provided with the mounting groove, and the through hole penetrates the base so that the second gear portion of the damper can extend into the receiving groove to mesh with the first gear portion provided on the sidewall of the operating handle.

[0022] The above scheme ensures that the second gear part of the damper and the first gear part of the operating handle are accurately aligned, avoiding wear or failure caused by meshing deviation; the fixing column enhances the installation strength of the damper and prevents loosening under vibration.

[0023] 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.

[0024] 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 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 of the rotating seat extends downward near the two side walls of the base to form a fixing wall for fixing the pull cable and a trigger wall capable of triggering the micro switch; wherein the rotating seat is provided with the first gear portion near the fixing wall.

[0025] The above solution provides stable rotational support for the rotating shaft, ensuring smooth rotation of the operating handle; the reset component provides automatic springback force to ensure the operating handle resets, preventing mechanical lock malfunctions caused by users forgetting to reset; the rotating base integrates multiple functions: rotational connection, pull wire fixing, and micro switch triggering, with a reasonable structure and clear functions; the bottom of the first receiving slot has a through-hole design to avoid rotational interference and ensure smooth rotation of the operating handle.

[0026] In some embodiments, the reset member includes an elastic member, one end of which abuts against the base and the other end against the operating handle, so that the elastic member can give the operating handle a tendency to rotate in the reset direction.

[0027] Specifically, the elastic element is a torsion spring.

[0028] 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 elastic member; the base is provided with a second engaging groove for engaging the other end of the elastic member at the end of the rotating seat away from the handle.

[0029] The above solution utilizes the elastic properties of the torsion spring to provide a stable and continuous restoring force, ensuring that the operating handle automatically returns to its initial position. The structure is simple and highly reliable. The first and second locking grooves fix the two ends of the torsion spring to prevent it from shifting or falling off.

[0030] In some embodiments, a buffer device is provided between the base and the operating handle, and the operating handle can abut against the buffer device after it springs back to its original position.

[0031] By adopting the above solution, the buffer device absorbs the impact energy when the operating handle is reset, reduces noise and prevents component impact damage, reduces the instantaneous stress on the rotating shaft, improves overall durability, and extends service life.

[0032] In some embodiments, the buffer device includes a buffer pin, which 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.

[0033] 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.

[0034] With the above solution, the buffer pin is placed near the micro switch to protect it; the contact surface cooperates with the buffer pin to buffer the impact force and limit the reset position of the operating handle to avoid overshoot.

[0035] In some embodiments, the micro switch is triggered when the operating handle is rotated 7°.

[0036] In some embodiments, the maximum rotation angle of the operating handle is 40°, and when the operating handle is rotated 40°, the zipper mechanism unlocks the mechanical lock.

[0037] Specifically, after the operating handle is rotated 7°, the trigger wall rotates 3.5mm, that is, the chord length between the initial position and the rotated position of the trigger wall is 3.5mm; after the operating handle is rotated 40°, the pull line moves 12mm, that is, the distance between the initial position and the moved position of the pull line is 12mm.

[0038] Using the above scheme, the micro switch is triggered when the operating handle is rotated 7°, which is sensitive and avoids misoperation; the mechanical lock is unlocked when the operating handle is rotated 40°, ensuring sufficient operating stroke; the electronic lock is triggered first (7°) and then the mechanical lock is unlocked (40°), ensuring that the electronic lock is activated first and improving the user experience.

[0039] In some embodiments, one of the operating handle and the base is elastically connected by a tick pin; the other of the operating handle and the base is provided with a recess that can cooperate with the tick pin; and when the operating handle is rotated to trigger the micro switch, the tick pin is precisely positioned in the recess.

[0040] In some embodiments, the base has a recess on the side wall of the first receiving groove, and the tick pin is provided on the side wall of the rotating seat of the operating handle. A spring is provided between the tick pin and the rotating seat, which gives the tick pin a tendency to always move towards the base. The recess is located on the movement path of the operating handle. When the operating handle is rotated to trigger the micro switch, the tick pin will move into the recess under the action of the spring and make an impact to generate a sound, so as to give the operator a prompt sound of electronic lock unlocking.

Using the above solution, the resistance of the damper 500 is evenly transmitted to the operating handle 200 through the meshing of the first gear portion 201 and the second gear portion 501, achieving more precise speed control. In some embodiments, the damper 500 is fixed to the base 100, and the second gear portion 501 is provided at one end of the damper 500 facing the operating handle 200.

In some embodiments, the reset component includes an elastic element 700, one end of which abuts against the base 100, and the other end against the operating handle 200, so that the elastic element 700 can give the operating handle 200 a tendency to rotate in the reset direction. Specifically, the elastic element 700 is a torsion spring. In some embodiments, a first engaging groove 205 for engaging one end of the elastic member 700 is provided at the connection between the rotating seat 203 and the handle 204; a second engaging groove 104 for engaging the other end of the elastic member 700 is provided at the end of the base 100 located on the rotating seat 203 away from the handle 204. Using the above scheme, the elastic characteristics of the torsion spring provide a stable and continuous restoring force, ensuring that the operating handle 200 automatically returns to its initial position. The structure is simple and highly reliable. The first engaging groove 205 and the second engaging groove 104 fix both ends of the torsion spring, preventing the torsion spring from shifting or falling off.

[0071] In some embodiments, a buffer device is provided between the base 100 and the operating handle 200, allowing the operating handle 200 to spring back and abut against the buffer device.

[0072] In some embodiments, the micro switch 300 is triggered when the operating handle 200 rotates 7°. In some embodiments, the maximum rotation angle of the operating handle 200 is 40°, and the pull lock mechanism 400 unlocks the mechanical lock when the operating handle 200 rotates 40°.

Using the above scheme, triggering the micro switch 300 when the operating handle 200 rotates 7° ensures a sensitive response and avoids misoperation; unlocking the mechanical lock when the operating handle 200 rotates 40° ensures sufficient operating travel; triggering the electronic lock first (7°) and then unlocking the mechanical lock (40°) ensures that the electronic lock is activated first, improving the user experience.

[0073] In some embodiments, the base 100 has a recess 10b on the side wall of the first receiving groove 1031, and the tick pin 10a is provided on the side wall of the rotating seat 203 of the operating handle 200.
