[0009] The present invention will be further described below in conjunction with the accompanying drawings.

[0010] In the figure: an outer handle for heavy trucks and light trucks, including an outer handle seat 1, a lock core subassembly 16, and an outer opening return spring 9, characterized in that: a sealing gasket 4 is hot-welded at the bottom of the outer handle seat 1; the lock core decorative cover 5 is fastened to the outer handle seat 1 by a self-tapping screw B14; the outer handle lower cover 2 and the outer handle upper cover 3 clamp the shock-absorbing pad 6 together to form an outer handle assembly; the lock core subassembly 16 is fastened to the outer handle assembly by a retaining ring 17; the outer handle assembly is fixed to the door by an outer handle insert 15, and the outer handle assembly is fixedly connected to the outer opening rocker arm 7 by an outer opening rocker arm shaft 10 and a clamp ring 11; the outer opening rocker arm 7 is fixedly connected to the outer handle seat 1 by an opening arm shaft 12 and a clamp ring 11, and an outer opening joint 8 is also provided on the outer opening rocker arm 7, and a cable is provided on the outer opening joint 8. The outer handle upper cover 3 is provided with a chrome-plated layer.

[0011] In specific implementation, the outer handle assembly is fixed on the vehicle door through the outer handle insert 15, the lock core decorative cover 5 and the outer handle upper cover 3 play a decorative role, and the sealing gasket 4 plays a sealing and decorative role. The outer handle assembly drives the outer opening rocker arm 7 to rotate, which is transmitted to the outer opening rocker arm of the vehicle door lock through the cable on the outer opening joint 8, thereby opening the vehicle door; the clockwise and counterclockwise rotation of the key drives the rocker arm of the lock core subassembly to rotate, and the rocker arm drives the unlocking rocker arm of the vehicle door lock to rotate through the connecting rod, thereby achieving the effect of unlocking and locking the vehicle door. Similarly, the electric unlocking and locking of the vehicle door lock can drive the unlocking rocker arm of the vehicle door lock to rotate, which is transmitted to the outer handle assembly through the connecting rod to drive the rocker arm of the lock core subassembly, thereby achieving the two-way transmission of the unlocking and locking functions.

[0012] The present invention uses a retaining spring 17 to fix the lock core subassembly 16 on the outer handle assembly. The outer handle assembly integrates the lock core and has the function of unlocking and locking the car door. It is also easy to install and disassemble. At the same time, the lock core and the outer handle assembly are integrated with the door lock and the outer locking transmission has the characteristics of relatively high precision. Compared with the traditional heavy truck and light truck lock core and the outer handle are separated, it has the advantages of compact structure, saving door assembly space and assembly process, and saving cost. The present invention is provided with a lock core decorative cover, and the outer handle is divided into an upper cover and a lower cover. Compared with the traditional heavy truck and light truck lock core decorative cover and the handle seat are integrated, the outer handle is integrated, and the shape is beautiful and changeable. Because the outer handle is an appearance part, the traditional outer handle is limited by cost and material strength. Generally, the handle surface is not chrome-plated, which cannot meet the aesthetic requirements of customers. The lock core decorative cover of the present invention is separated from the handle seat, and the outer handle is divided into an upper cover and a lower cover. The lock core decorative cover and the outer handle upper cover can be surface-treated separately, such as chrome-plating. The outer handle is divided into an upper cover and a lower cover. The upper cover of the outer handle and the lower cover of the outer handle can clamp and fix the shock-absorbing pad 6 in the middle. In this way, the shock-absorbing pad does not need to be glued on one side, is not easy to wrinkle, and has accurate assembly and positioning. The traditional heavy truck and light truck outer handles are generally glued to the outer handle. This method is limited by the material of the shock-absorbing pad and has the disadvantages of loose adhesion, easy wrinkles, and inaccurate positioning with the handle. The rotating part of the outer handle assembly adopts the method of matching the shaft and the clamp ring to prevent axial separation, which has the advantages of easy installation and easy disassembly; while the open cylindrical pin or shaft riveting method used in the rotating part of the outer handle of the traditional heavy truck and light truck is complicated to assemble, and is not easy to disassemble after assembly, and it is not easy to recycle parts. The outward opening rocker arm 7 is fixedly connected to the outer handle lower cover 2, and the outward opening rocker arm is fixedly connected to the door lock outward opening rocker arm through a cable to achieve the function of opening the door. The transmission is simple and has the advantages of high transmission efficiency, light weight, and stable performance. However, traditional heavy truck and light truck outer handles use a large number of zinc alloy parts and connecting rod transmission. The transmission mechanism is complex and has the disadvantages of low transmission efficiency, high cost, heavy weight, and unstable performance.

[0013] The above embodiments of the present invention are merely examples to clearly illustrate the present invention, but are not intended to limit the protection scope of the present invention. All equivalent technical solutions also belong to the scope of the present invention. The patent protection scope of the present invention should be defined by the claims.
