Description

Control rod pre-installation structure of vehicle door handle Technical Field The utility model relates to the technical field of automobile parts, in particular to a control rod pre-installation structure of a vehicle door handle. Background The door handle is one of the highest frequency components of the vehicle, and a complex mechanical linkage mechanism is usually arranged in the door handle and is used for transmitting the action of pulling the handle by a user to the door lock so as to unlock and open the door. The existing automobile door handle is generally composed of an external handle shell and an internal mechanical transmission mechanism, the core of the internal mechanism is a rotatable control rod, the rotatable control rod is arranged on a handle base for fixing a door sheet metal through a connecting rotating shaft, one end of the control rod is connected with a door lock mechanism through a pull rope or a connecting rod, the other end of the control rod is provided with a connecting part matched with the connecting end of the external handle, and the control rod is connected with the handle through the connecting part to realize the installation of the handle. However, because the door handle in the prior art lacks a pre-tightening structure, an operator needs to align the connecting end of the external handle with the connecting part on the control rod, but because the control rod is not positioned effectively, the connecting part is often not positioned at the right position, so that the operator must extend into a narrow space with fingers or tools, stir and forcedly slide the control rod to a proper position, and coordinate the other hand to push and clamp the connecting end of the handle while maintaining the state, the whole process requires the two hands to operate cooperatively under a limited visual field, which is time-consuming and laborious, and is very easy to cause assembly failure or part damage due to inaccurate alignment or improper force, and is a main bottleneck affecting the assembly efficiency and quality. Disclosure of utility model In order to solve the technical problems in the background art, the control rod pre-installation structure of the vehicle door handle is provided. The utility model solves the technical problems by adopting the following technical scheme: The control rod pre-installation structure of the vehicle door handle comprises a handle base connected with a vehicle door metal plate and a handle arranged on the handle base, wherein a connecting rotating shaft is inserted into the handle base, a control rod is slidably arranged on the connecting rotating shaft and is connected with an unlocking pull rope, a pre-tightening spring is sleeved on the connecting rotating shaft, one end of the pre-tightening spring is abutted to the handle base, and the other end of the pre-tightening spring is abutted to the control rod, so that the control rod is kept at the current position; The handle base is provided with a connecting groove for placing the unlocking end of the handle, the control rod is provided with a connecting part, the connecting part is kept in the insertion path of the unlocking end under the action of the pre-tightening spring, the unlocking end supports and presses the connecting part through the connecting groove, the connecting part slides away from the direction of the connecting groove and compresses the pre-tightening spring, and the pre-tightening spring drives the control rod to reset, so that the connecting part is clamped with the unlocking end and transmission is formed. Preferably, the clamping groove for the connecting part to be placed in is formed in the side part of the unlocking end of the handle, through the improvement, when the control rod is reset under the action of the pre-tightening spring, the connecting part can directly enter the clamping groove from the side part, so that the quick clamping with the handle is realized, and compared with a conventional automobile door outer handle structure, the assembly speed and the assembly efficiency are further improved. Preferably, the unlocking end of the handle is provided with a driving inclined plane, the driving inclined plane is abutted against the connecting part and forces the connecting part to be far away from the connecting groove, through the improvement, the connecting part of the control rod can be smoothly pushed when the unlocking end is inserted into the connecting groove by arranging the driving inclined plane, so that the pre-tightening spring is compressed, the control rod is prevented from being bent, an operator is not required to operate the control rod at the back of the sheet metal of the vehicle door in the process, and the operation smoothness is further improved. Preferably, a first positioning convex part is formed on the handle base, a second positioning convex part is formed on the control rod, two ends of the pre-tightening spring are respectivel
