Description

Technical Field

[0001] This utility model relates to the field of car door handle technology, and in particular to a car door handle base assembly that is easy to install. Background Technology

[0002] Automotive parts are the various units that make up a car and the products that serve the vehicle. There are many types of automotive parts, and as people's living standards improve, their car consumption is increasing, leading to a growing market for automotive parts. In recent years, automotive parts manufacturing plants have also developed rapidly. During the car production process, car door handles are generally assembled manually. Existing door handles are typically connected to their bases using bolts. The bolt installation process can affect worker assembly efficiency, thus impacting the overall vehicle production time.

[0003] In view of this, Chinese utility model patent CN223104345U discloses an easy-to-install car door handle base assembly, including a car door handle and a handle base body disposed below it. The upper end of the handle base body has a first connecting groove and a second connecting groove. A snap-fit ​​hollow block is disposed in the first connecting groove, and a second connecting block is disposed in the second connecting groove. A snap-fit ​​element is disposed in the first connecting groove for snapping the hollow block to connect with the first connecting groove. Both sides of the second connecting block have contraction grooves, and both side walls of the second connecting groove have circular snap-fit ​​holes, with circular inserts slidably disposed within each circular snap-fit ​​hole. When the second connecting block is inserted into the second connecting groove, the circular inserts are compressed and contract into the contraction groove, and the first spring is in a compressed state. At this time, the second connecting block is connected to the handle base body. However, this method uses two different fixing methods between the two ends of the car door handle and the handle base body, and the structure is complex, has many parts, is costly, and has poor stability.

[0004] Therefore, it is necessary to improve upon the shortcomings of the existing technologies mentioned above. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an easy-to-install car door handle base assembly to address the shortcomings of the prior art, thereby solving the problems of complex connection structure, numerous parts, high cost, and poor stability of the car door handle and base in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-install car door handle base assembly, including a car door handle and a handle base body disposed below it. The upper end of the handle base body has connecting grooves on both sides. The lower end of the car door handle has connecting blocks on both sides that can be inserted into the connecting grooves. Each connecting block has an installation groove communicating with the upper end of the car door handle. A cover plate is detachably installed at the upper opening of the installation groove. A first rotating shaft is rotatably connected to the center of the cover plate. A first bevel gear is installed at the lower end of the first rotating shaft. A second rotating shaft is rotatably connected to the inner walls of both sides of the installation groove. A second bevel gear meshing with the first bevel gear is installed in the center of the second rotating shaft. External threads in opposite directions are provided on both sides of the second rotating shaft at the external threads. A slider is helically driven on the lower end of the second rotating shaft away from the second bevel gear. A pin is provided on the side wall of the installation groove for the pin to slide through. A pin hole is provided on the side wall of the connecting groove for the pin to be engaged.

[0007] By adopting the above technical solution, the first rotating shaft is rotated, which drives the first bevel gear to rotate. The first bevel gear meshes with the second bevel gear, causing the second rotating shaft to rotate. The positive and negative external threads on both sides of the second rotating shaft drive the slider to move towards or away from each other, thereby driving the pin to pass through the clearance hole and engage or disengage from the pin hole, realizing the quick connection and disassembly of the door handle and the handle base body. The assembly is convenient and the structure is simple.

[0008] A further provision of the above technical solution is as follows: the lower ends of the two side walls of the mounting groove are provided with a first step platform, the middle part of the first step platform is provided with a first semi-arc groove adapted to the lower end of the second rotating shaft, the lower ends of the cover plate are provided with limiting feet, and the lower ends of the limiting feet are provided with a second semi-arc groove adapted to the upper end of the second rotating shaft.

[0009] Using the above technical solution, the first semi-circular groove and the second semi-circular groove cooperate to limit and support the second rotating shaft, enhance the stability of the second rotating shaft when it rotates, prevent it from deviating, and ensure that the pin is accurately engaged in the pin hole.

[0010] A further provision of the above technical solution is that: the cover plate has a rotating hole in the middle that is rotatably connected to the first rotating shaft, and the upper end of the first rotating shaft has an internal hexagonal groove.

[0011] Using the above technical solution, the rotating hole provides rotational support for the first rotating shaft, and the internal hexagonal groove facilitates the use of an internal hexagonal tool to rotate the first rotating shaft, making the operation more convenient and labor-saving.

[0012] A further provision of the above technical solution is as follows: the upper end of the cover plate is provided with mounting ears on both sides, the mounting ears are provided with a countersunk hole in the middle, the upper end of the mounting groove is provided with a second stepper that abuts against the mounting ears on both sides, and the countersunk hole is provided with a fastening bolt that is threadedly connected to the second stepper.

[0013] By adopting the above technical solution, the cover plate and the mounting groove are detachably connected by fastening bolts passing through the countersunk hole and threaded to the second ladder platform. This facilitates the inspection and replacement of internal components in the mounting groove, and the connection is stable and reliable.

[0014] The beneficial effects achieved by this utility model are: the assembly process of the door handle and the handle base body is quick and convenient, the structure is simple, there are few parts, the cost is reduced, and the connection stability is good. Attached Figure Description
