Attached Figure Description

[0022] To more clearly illustrate the specific embodiments of the present invention, the accompanying drawings used in the embodiments will be briefly described below.

[0023] Figure 1 This is a schematic diagram of an inner handle for releasing a car door lock provided by the present invention.

[0024] Figure 2 This is an exploded schematic diagram of the inner handle for releasing the door lock provided by the present invention. Detailed Implementation

[0025] To enable those skilled in the art to better understand the embodiments of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and implementation methods.

[0026] To address the inconvenience of using current mechanical car door handles and concerns about the failure of electronic unlocking, this invention provides an inner door lock release handle. This solves the problems of inconvenience and electronic unlocking failure in existing car door handles, enabling safe and controllable vehicle door handles and improving the security and intelligence of door unlocking.

[0027] like Figure 1 and Figure 2 As shown, a door lock release handle includes: a handle base 1, a piezoelectric ceramic 2, a mechanical unlocking handle 3, and a mechanical pull cable 8. The handle base 1 has a mounting groove, and the mechanical unlocking handle 3 is rotatably mounted within the mounting groove around a rotating shaft 5. The piezoelectric ceramic 2 is located at the handle end of the mechanical unlocking handle 3, and the pull cable end of the mechanical unlocking handle 3 is connected to the door lock via the mechanical pull cable 8. When the handle of the mechanical unlocking handle 3 is pulled up, it drives the mechanical pull cable to pull the door lock and open the door. The piezoelectric ceramic 2 is electrically connected to the unlocking control PCB board via a wiring harness. When pressed, the piezoelectric ceramic converts mechanical energy into an electrical signal, causing the unlocking control PCB board to send an unlocking signal to the vehicle computer, which then controls the door lock to electronically unlock.

[0028] Specifically, the handle base provides space for the installation, protection, and operation of the mechanical unlocking handle. The mounting groove on the handle base can be a hollow structure to allow passage for the mechanical pull cable and wiring harness. The mechanical unlocking handle is fixed to the handle base via a rotating shaft and can rotate around the shaft. The traction force and stroke difference generated during rotation provide the energy and actuation stroke required for the mechanical opening of the door, thus realizing the mechanical opening function. The mechanical pull hook end of the door unlocking mechanism engages with the mechanical unlocking handle, and the mechanical pull cable protector / sleeve is engaged and fixed to the handle base. Pulling the mechanical unlocking handle upward causes the handle to rotate around the fixed shaft, moving the mechanical pull cable within the protector and pulling the door lock to unlock the door. When the handle end of the mechanical unlocking handle is pulled up, the pull cable end of the mechanical unlocking handle tilts up and pulls the mechanical pull cable, thereby actuating the door lock unlocking switch connected to the mechanical pull cable, and thus unlocking the door. Meanwhile, the mechanical unlocking handle has a piezoelectric ceramic at its handle end. When the piezoelectric ceramic is pressed, it converts mechanical energy into an electrical signal, causing the PCB board connected to the piezoelectric ceramic to send an unlocking signal to the vehicle's computer. The vehicle's computer then controls the door lock to open and unlock. This handle integrates electronic and mechanical control, allowing for convenient electronic unlocking of the door lock as well as mechanical unlocking. Even when the vehicle battery is depleted or the electronic unlocking mechanism fails due to an emergency, the mechanical unlocking handle can still effectively and conveniently unlock the door, improving the safety and controllability of the vehicle door handle and enhancing the security and intelligence of door unlocking.

[0029] Furthermore, the handle end of the mechanical unlocking handle is provided with a marking area, and the piezoelectric ceramic is disposed within the marking area.

[0030] In practical applications, the marked area has an open sign. When the user presses it, it directly acts on the piezoelectric ceramic, causing the piezoelectric ceramic to be stressed and converting mechanical energy into an electrical signal.

[0031] Furthermore, the piezoelectric ceramic is fixed inside the mechanical unlocking handle by screws or integral injection molding.

[0032] The handle also includes a return spring 6; the return spring 6 is sleeved on the rotating shaft, one end of the return spring is connected to the handle end of the mechanical unlocking handle, and the other end of the return spring is connected to the handle base; when the handle of the mechanical unlocking handle is pulled up, the return spring is compressed and deformed, and after the handle operation is released, the mechanical unlocking handle returns to its initial state under the action of the return spring.

[0033] The handle also includes a buffer elastic element 7; the buffer elastic element 7 is disposed on the inner side of the mounting groove that contacts the mechanical unlocking handle, so as to buffer the impact when the mechanical unlocking handle returns to its original position and reduce the return noise.

[0034] The handle also includes a decorative ring 4; the decorative ring 4 is embedded in the inner periphery of the mounting groove, and the handle of the mechanical unlocking handle is located within the decorative ring 4.

[0035] Furthermore, the decorative ring is made of an elastic material.

[0036] Furthermore, symmetrical rotating shaft supports are provided on both sides of the mounting groove, and the mechanical unlocking handle is rotatably mounted on the rotating shaft supports via the rotating shaft.

[0037] Furthermore, the handle base is a folded plate structure, and the edge of the handle base is provided with a fixing through hole, which is then bolted to the car door.

[0038] Furthermore, the mechanical unlocking handle has a rocker-shaped structure.

[0039] As can be seen, this invention provides a door lock release handle. A piezoelectric ceramic is provided at the handle end of the mechanical unlocking handle. The piezoelectric ceramic converts the mechanical energy of pressing into an electrical signal, achieving electronic unlocking. The mechanical unlocking handle is rotatably mounted on a handle base. When the handle of the mechanical unlocking handle is pulled up, the mechanical unlocking handle pulls the door lock via a mechanical cable to open it. This solves the problems of inconvenience for users and concerns about electronic unlocking failure in existing car door handles, enabling safe and controllable vehicle door handles and improving the security and intelligence of door unlocking.

[0040] The structure, features, and effects of the present invention have been described in detail above with reference to the embodiments shown in the figures. The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures. Any changes made in accordance with the concept of the present invention, or equivalent embodiments modified to have equivalent changes, shall be within the protection scope of the present invention as long as they do not exceed the spirit covered by the specification and figures.
