This method allows for rapid and mass production, utilizing a structure with embedded reinforcing components to strengthen the weaker areas of the original car door outside handle. It offers advantages such as simplified structure, reduced material usage, environmental friendliness, ease of production, and efficient mass production.

TECHNICAL FIELD

A method and structure for reinforcing the car door outside handle is used to replace a damaged car door handle, in particular to a car door outside handle which has a low cost, less material usage, is friendly to environment and easy to manufacture, which is more durable than the car door outside handle of the original factory or the car door outside handles of other manufacturers.

BACKGROUND

When automobile manufacturers produce car door handles, the quality of materials is the key factor affecting their durability and life. Usually, if low-quality or inferior materials are used in the manufacturing process, the structure of the car door handle may be unstable and easy to break or damage in use. The car door outside handle and the door usually have two fixed parts, one end is the pivot part and the other end is the hooking part that triggers the unlocking. Usually, automobile manufacturers will choose high-quality and durable materials to produce the car door handle to ensure its long-term reliability. However, the car door handle is usually a mechanical structure that needs to be actuated most often, and it is easy to break after being used for many times, because every time the door is opened and closed, it will lead to parts wear or fatigue cracks, and the car door handle is the most affected by temperature, humidity and sunshine because it is installed outside the car, and the aging speed is faster than other parts.

In addition, the design of the handle of some models of vehicles may also have structural defects. The design does not take into account that some users are used to opening the door vigorously, which leads to excessive force on the outside handle of the door after the door lock is opened, resulting in a slight crack in the parts, which will lead to the car door handle breaking over time, such as the 2019 Benz Spinter 9-seater car. The detailed reason is that when the user opens the door vigorously, although the door lock has been opened, because the owner pulls the door quickly and vigorously, the hooking part continues to be forced to drag the whole door. Generally, the car door outside handle is not designed to let the hooking part drag the door, but its design purpose is only suitable for opening the door lock. After opening, it will be reset by elastic parts, so that other resistant structures can be forced. Although most car door outside handles can usually withstand such rough use by the user, if the user is used to opening the door in this way, the door will be opened.

SUMMARY

In order to solve the problem that the fracture probability and service life of the hooking part of the car door outside handle will be greatly reduced, the invention relates to a reinforcing method of a car door outside handle, which is used for reinforcing the hooking part of the car door outside handle and replacing the damaged car door. The reinforcing structure of the car door outside handle of the invention is characterized by comprising a handle body, one end of which is a pivot end, and the other end is a trigger end, wherein the trigger end is provided with a hooking part protruding towards the door, and the hooking part has a stroke body and a trigger hook, one end of the stroke body is connected with the handle body, and the other end forms a hook-shaped trigger hook; and a reinforcing part with a reinforcing stroke body, one end of which forms a hook-shaped reinforcing trigger hook, and the reinforcing part is arranged at an appropriate place of the hooking part.

The main technical means of the present invention lies in that a reinforcing part is arranged at the proper place of the hooking part, and the mechanical strength of the hooking part is enhanced, so that the effect can be achieved by embedding or sticking, and the car door outside handle with the hooking part which is easy to break due to wear can be additionally provided with a reinforcing part accommodating part at the hooking part, and the reinforcing part accommodating part is arranged at the easy-to-wear place, and the original contacting surface of the hooking part is replaced by the reinforcing part; the reinforcing part can be made of metal and is more wear-resistant.

The method of the present invention is a manufacturing method of a reinforcing structure of a car door outside handle, which reinforces a hooking part of a car door handle, and includes the following steps: step S1, a measuring step: precisely measuring the hooking part of a car door outside handle; step S2, a designing step: designing a shape specification of the reinforcing part according to the shape data of the hooking part of the car door outside handle, wherein the reinforcing part needs to have a reinforcing stroke body, and one end of the reinforcing stroke body forms a hook-shaped reinforcing trigger hook; step S3, a manufacturing step: manufacturing a reinforcing part according to the design specification of the reinforcing part designed in step S2.

The secondary technical means of the present invention is to modify the car door outside handle reinforcement structure with the least number of components to obtain the lowest manufacturing cost, and to achieve the advantages of simplified structure, reduced material use, friendliness in environment, easy manufacture and rapid mass production, which can quickly mass produce and supply the market demand.
