[0033] The present invention is described in detail below with reference to the various embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in this field based on these embodiments are all within the scope of protection of the present invention.

[0034] Example 1

[0035] Refer to the attached Figure 1-8 As shown, the unlocking lever in this embodiment includes a rotating shell 2; the rotating shell forms a snail shell structure, and thus can be assembled with many structures, such as the unlocking lever spring 4 located in the rotating shell 2. Before assembly, it is first rotated so that the unlocking lever spring 4 forms a certain pre-tightening force, and then when used, it can provide a reverse force for the subsequent use. For example, in this embodiment, a return cantilever 8 is formed extending along the circumferential direction of the rotating shell 2. When the return cantilever 8 is driven by the force to rotate the rotating shell 2, the pre-tightening force formed by the unlocking lever spring 4 forms a return force that drives the force-applying mechanism to return, and then when used for locking, once an external force is applied to unlock, the return force can make the unlocking part have a tendency to return, and once the external force stops, it can automatically return.

[0036] The unlocking lever in this embodiment further includes a cable assembly hole 13 on the rotating housing to facilitate unlocking. The cable 3 in the cable assembly hole 13 is linked to a locking mechanism, which can be a vehicle door lock or other type of lock. In this case, locking requires external force to pull, thereby separating the components in the locking mechanism. For example, the locking can be achieved by magnetic attraction, and then the external force needs to overcome the magnetic attraction to unlock. In this embodiment, as the rotating housing rotates, the cable is also linked during the process of rotating from the locked position to the unlocked position. For example, the cable assembly hole has a slot on the side, and the cable is fixed to, for example, a vehicle door or other structure after passing through the slot. When the rotating housing begins to rotate, the cable does not rotate immediately due to the slot. However, after rotating to a certain angle, the cable is already in a taut state. As the rotation continues, the cable drives the structure to which it is connected, such as the locking structure of the vehicle door lock, to move, thereby completing the unlocking of the vehicle door lock.

[0037] The cable drives the lock tongue out of the lock catch, achieving unlocking. In this embodiment, the rotation of the rotating shell is fully utilized to make it move repeatedly along the set trajectory between the locked position and the unlocked position, achieving the interchangeability of locking and unlocking. The return force during unlocking can also drive the unlocking member back to its original position, achieving multiple goals at one stroke.

[0038] In this embodiment, a rotating housing 2 is provided with a rotating engaging structure 10. A slot 23 is formed between the rotating housing 2 and a protrusion extending from the rotating engaging structure 10. A through hole 17 is provided on the rotating housing 2 at a position offset from the slot 23, with the projection of the through hole 17 located at the slot 23. In this embodiment, the slot can be used to assemble the rotating housing with other structures in a horizontal or first direction, while the through hole 17 is located in a vertical or second direction. The through hole 17 is a square hole with arcs on two parallel sides, thereby providing a foundation for subsequent rotational assembly.

[0039] To facilitate subsequent interaction with other unlocking mechanisms, such as a microswitch, the side of the rotating housing 2 extends to form a staggered trigger mechanism 11 and a stop structure. The stop structure forms a limiter located within the trigger mechanism's trigger path. In this embodiment, the trigger mechanism 11 subsequently interacts with the microswitch 6 to generate a signal reminder, etc.

[0040] To ensure the proper assembly of the unlocking lever spring 4, the rotating housing 2 is provided with a prefabricated assembly slot 22 and a spring retaining slot 9 located to the side of the prefabricated assembly slot 22. The partially extended portion of the unlocking lever spring 4, which is placed in the prefabricated assembly slot 22, is fixed in the spring retaining slot 9. The extension to the other side allows the spring to be assembled in multiple directions. During rotation, the inner and outer springs can easily form a preload, making reset easier.

[0041] Example 2

[0042] In this embodiment, the door handle is taken as the core for introduction.

[0043] Refer to the attached Figure 1-4 As shown, this embodiment first includes an unlocking lever and a pull rod 1 linked to the door, and the pull rod 1 forms the force applying mechanism;

[0044] The housing 5 is further provided with the pull rod 1, and the door lock is then installed in the housing 5. The cable 3 passes through the cable assembly hole 13 and is fixed to the housing 5. In this case, the housing 5 can be the side of the vehicle body, and the regular unlocking lever is then installed in the vehicle body, near the door handle.

[0045] In order to facilitate the rotation of the rotating shell 2 , a sliding groove 15 is formed on the housing 5 . When the pull rod 1 moves along the sliding groove 15 , the rotating shell 2 is driven to rotate.

[0046] To mitigate inertia during driving, an inertia lock 7 is installed on the housing 5 near the unlocking lever. During inertia, the inertia lock 7 and the rotating housing 2 rotate in opposite directions, engaging and stopping the rotation at a set position. Specifically, the inertia lock 7 is rotatably mounted on the positioning post 6 of the housing 5. The inertia lock 7 extends to form a locking structure 19 that engages with a stop structure on the rotating housing 2.

[0047] In this embodiment, a through hole 17 is provided on the surface of the rotating shell 2, and a rotating clamping structure 10 is provided on the inner side, and then a clamping groove 23 is formed between the outer shell of the rotating shell 2 and the rotating clamping structure 10. The rotating clamping structure 10 in this embodiment is a hollow cylinder, and the hollow cylinder is grooved on both sides along the direction of the hollow cylinder away from the through hole 17, and then an inner tube (not shown in the figure) is inserted into the groove body, and a square structure extends on both sides of the inner tube to form a protrusion, and the above-mentioned clamping groove 23 is formed between the square structure and the outer shell of the rotating shell 2. At this time, the through hole 7 is specifically a square hole, and the straight edge of the square hole at the corresponding position with the square structure becomes an arc, and then the through hole 7 here is a square hole with arcs on both sides, and its structure is consistent with the cross section of the bottom of the clamping groove.

[0048] For assembly, an assembly hole is provided on the shell 5, and the assembly hole has the same structure as the through hole 17. During use, the cubic structure extending from the inner tube of the rotating shell 2 is inserted into the shell 5 through the assembly hole and rotated to a set angle so that the cubic structure is misaligned with the cubic structure on the assembly hole, thereby achieving the clamping of the shell and the rotating shell.

[0049] Example 3

[0050] In this embodiment, the usage process and the like are introduced.

[0051] There are multiple different structures on the unlocking lever, which interact with its matching parts to achieve rotational connection with the housing, circular motion around the card node on the housing, assemble and fix the spring, return the pull rod, pull the car door cable, trigger the micro switch, cooperate with the inertia lock to achieve inertia resistance stop and other functions.

[0052] The multifunctional unlocking lever in this embodiment comprises a return cantilever 8, a spring receiving slot (i.e., a prefabricated assembly slot), a spring retaining slot 9, a cable assembly hole 13, a cable receiving slot, an inertia lock mechanism, a microswitch trigger mechanism, and a rotary latch mechanism. The pull rod, unlocking lever, cable, unlocking lever spring, microswitch, and inertia lock are all assembled on the housing. The unlocking lever can now perform the following functions:

[0053] Unlocking lever spring can be assembled: the unlocking lever spring is first assembled in the spring receiving slot, one end of which is clamped in the spring clamping slot on the unlocking lever, the unlocking lever spring is rotated to keep a certain pre-tightening amount, and then the other end is assembled in the unlocking lever spring pre-installation slot to realize spring pre-installation;

[0054] Rotational snap-fitting can be achieved: the unlocking lever is assembled with the corresponding contoured hole on the shell through the rotational snap-fitting structure thereon, and then the pin at the other end of the unlocking lever spring is clamped in the slot on the shell, and the unlocking lever can rotate around the slot on the shell without the need for other connection and assembly structures, saving the number of parts and costs; in this embodiment, a through hole 17 is provided on the rotational snap-fitting structure, which has a certain rotation range with the assembly hole on the shell 5, and then the rotating rod on the shell is extended into the through hole 7 and fits in the arc-shaped assembly track, thereby being able to drive the entire rotating shell to rotate along the shell 5.

[0055] The pull rod can be returned to its original position: when the pull rod 1 moves in the slide groove on the housing 5, it is always in contact with the return cantilever on the unlocking lever. The two are in a driven relationship. Because the unlocking lever spring is always in a pre-tightened state, the return cantilever will always give the pull rod a return force to realize the pull rod return;

[0056] The door lock can be unlocked by pulling the cable 3: the cable 3 is inserted into the cable receiving groove through the cable assembly hole 13 on the unlocking lever. The cable is kept in an upright state on the ribs of the cable receiving groove and the housing. Then the other end of the cable is connected to the door lock. At this time, the cable 3 can slide in the receiving groove. When the pull rod 1 is pulled to drive the unlocking lever to rotate to a certain angle, the cable 3 can be pulled to unlock the door lock.

[0057] It can prevent the inertia-resistant door from opening accidentally: when the car is hit from the side, due to the effect of inertia, the inertia lock will rotate around the positioning column 16 on the housing 5 to the specified position. Due to the effect of inertia, the pull rod 1 will pull the unlocking lever. When the unlocking lever rotates to a certain angle, the inertia lock position structure on the unlocking lever will hit the stop structure on the inertia lock 7, so that the unlocking lever is restricted from rotating. The unlocking lever will not continue to pull the cable, and the door lock cannot be unlocked, thus ensuring the safety of the vehicle.

[0058] It can cooperate with the whole vehicle to do signal triggering: when the unlocking lever is pulled to a certain angle by the pull rod, the trigger mechanism 11 on the unlocking lever can trigger the micro switch 6 assembled on the shell, realizing the glass short drop signal or electronic lock signal of the whole vehicle.

[0059] The unlocking lever in this embodiment comprises a return cantilever 8, a spring receiving slot 21, a pre-installation slot 19, a spring retaining slot 9, a cable assembly hole 13, a cable receiving slot 20, a retaining structure 12, a trigger mechanism 11, and a rotary retaining structure 10. The pull rod 1, unlocking lever 2, cable 3, unlocking lever spring 4, micro switch 6, and inertia lock 7 are all assembled on the housing 5. The unlocking lever 2 can now perform the following functions:

[0060] The unlocking lever spring 4 can be assembled: the unlocking lever spring 4 is first assembled in the spring receiving groove 21, one end of which is clamped in the spring clamping groove 9 on the unlocking lever 2, and the unlocking lever spring 4 is rotated to keep a certain pre-tightening amount of the unlocking lever spring 4, and then the other end is assembled in the pre-installation clamping groove 19 of the unlocking lever spring 4 to realize the pre-installation of the unlocking lever spring 4;

[0061] The unlocking lever 2 can be rotated and engaged with the through hole 17 formed by the corresponding contoured hole on the housing 5 through the rotary engaging structure 10 thereon. Then, the pin at the other end of the unlocking lever spring 4 is engaged in the slot 14 on the housing 5. The unlocking lever 2 can then rotate around the through hole 17 on the housing. No other connection and assembly structure is required, thus saving the number of parts and costs.

[0062] The pull rod 1 can be returned to its original position: when the pull rod 1 moves in the slide groove 15 on the housing 5, it always keeps in contact with the return cantilever 8 on the unlocking lever 2, and is in a driven relationship. Because the unlocking lever spring 4 is always in a pre-tightened state, the return cantilever 8 on the unlocking lever 2 will always apply a return force to the pull rod 1, thereby returning the pull rod 1 to its original position;

[0063] The door lock can be unlocked by pulling the cable 3: the cable 3 is inserted into the cable receiving groove 20 through the cable assembly hole 13 on the unlocking lever 2. The cable 3 is kept in an upright state on the cable receiving groove 20 and the rib 18 of the housing 5. The cable can be pulled and slides along the cable receiving groove 20. When the pull rod 1 is pulled to drive the unlocking lever 2 to rotate to a certain angle, the cable 3 can be pulled to unlock the door lock.

[0064] It can prevent the inertia-resistant door from opening accidentally: when the car is hit from the side, due to inertia, the inertia lock 7 will rotate around the positioning column 16 on the housing 5 to the specified position. Due to the action of inertia, the pull rod 1 will pull the unlocking lever 2. When the unlocking lever 2 rotates to a certain angle, the inertia lock stop structure 12 on the unlocking lever 2 will hit the stop structure 19 on the inertia lock 7, restricting the rotation of the unlocking lever 2. The unlocking lever 2 will not continue to pull the cable 3, and the door lock cannot be unlocked, thus ensuring the safety of the vehicle in the event of a collision.

[0065] It can cooperate with the whole vehicle to perform signal triggering: when the unlocking lever 2 is pulled to a certain angle by the pull rod 1, the micro switch triggering structure 11 on the unlocking lever 2 can trigger the micro switch 6 assembled on the shell 5, realizing the glass short drop signal or electronic lock signal of the whole vehicle.
