Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steering accessories, in particular to a steering column and a drive shaft assembly. Background Technique
[0002] The steering column is an important part of the vehicle steering system. It connects the steering wheel and the steering gear, transmits the driver's steering operation, and ensures that the vehicle can change its direction according to the driver's intention. The structural design of the steering column directly affects the handling performance and safety of the vehicle.
[0003] The existing steering columns usually adopt a fixed installation method, that is, the position of the bracket is preset during the manufacturing process for installation on the vehicle frame. However, this fixed design has some deficiencies. Since the frame structures and hole positions of different vehicle models are not the same, the fixed brackets may not be fully adapted to all vehicle models, resulting in a complicated installation process and even the need for additional processing and adjustment. Content of the Utility Model
[0004] The purpose of the utility model is to provide a steering column and a drive shaft assembly to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A steering column and a drive shaft assembly, including a column body, a movable bracket and a fixed bracket. A sliding opening is provided in the middle of the movable bracket, and the column body is inserted into the inside of the sliding opening. Extension blocks are inserted into the two ends of the fixed bracket, and the column body is fixed in the middle of the fixed bracket. One end of the column body is connected to a turntable, and a shaft seat is connected to the surface of the turntable.
[0006] When using the steering column and the drive shaft assembly in the present technical solution, the staff can first install it. The installation steps are as follows: The staff determines the length of the extension block according to the holes opened at the installation position. After determination, the extension blocks inserted into the two ends of the fixed bracket are pulled. After pulling, the first bolt is inserted into the overlapping first fixing hole and the second fixing hole, and then inserted into the hole opened on the vehicle bracket and tightened, so as to connect the fixed bracket to the vehicle frame. After connection, the staff moves the movable bracket to move the movable bracket on the surface of the column body. When it moves to the specified fixed connection position, the staff stops moving the movable bracket, inserts the second bolt into the third fixing hole and directly screws it into the hole opened on the vehicle frame for fixed connection. After connection, the staff connects the first connecting rod to the drive shaft, and finally connects and installs structures such as the steering wheel using the second connecting rod. In this way, the utility model can be used.
[0007] Preferably, a shaft rod is rotatably installed inside the shaft seat, and a first connecting rod is connected to the surface of the shaft rod. Through the cooperation of the turntable, the shaft seat and the shaft rod, the transmission shaft connected to the first connecting rod can perform angle conversion, achieving the effect of multi-angle movement. By setting the first connecting rod, the column body can be connected to the transmission shaft, achieving the effect of connection and installation.
[0008] Preferably, the other end of the column body is connected with a second connecting rod. By setting the second connecting rod, the steering wheel can be connected to the column body, achieving the effect of connection and installation.
[0009] Preferably, a third fixing hole is penetrated through the side surface of the movable frame, and a second bolt is inserted into the third fixing hole. Through the cooperation of the second bolt and the third fixing hole, the movable frame can be connected to the vehicle bracket, achieving the effect of fixed connection. The installation of the movable frame enables one end of the column body to be adapted to be connected to the vehicle bracket.
[0010] Preferably, first fixing holes are penetrated through the top and bottom surfaces at both ends of the fixing frame, and a first bolt is inserted into the first fixing holes. The installation of the fixing frame enables the other end of the column body to be adapted to be connected to the vehicle bracket. Through the cooperation of the first bolt, the first fixing holes and the second fixing holes, the extension block can be fixed inside both ends of the fixing frame, achieving the effect of fixing the extending and retracting distances of the extension block.
[0011] Preferably, one end of the first bolt is inserted into the second fixing hole, and the second fixing hole is opened inside the extension block. By setting the extension block, the fixing frame can be adaptively connected and fixed to the vehicle bracket, achieving the effect of adaptively connecting by elongation and shortening.
[0012] Compared with the prior art, the beneficial effects of the present utility model are:
[0013] 1. The movable frame provided inside the present utility model can slide on the surface of the column body, flexibly adapt to the hole positions of different vehicle models, simplify the installation process, reduce the adjustment time. The fixing frame is provided with a telescopic extension block, which can accurately adjust the position according to actual needs. After aligning the hole positions, the bolts can be easily screwed in to ensure firm fixation. This design not only improves the convenience and adaptability of installation, but also enhances the stability and safety of the system during use, greatly improving the overall reliability.
