Description

Technical Field

[0001] The utility model belongs to the technical field of steering columns, and particularly relates to a steering column mounting bracket and a steering column assembly. Background Art

[0002] An automobile steering column assembly includes an upper column tube, a lower column tube, an upper steering shaft, a lower steering shaft, an upper mounting bracket and a lower mounting bracket. The upper end of the lower column tube is sleeved inside the lower end of the upper column tube. The upper steering shaft is arranged inside the upper column tube, and the lower steering shaft is arranged inside the lower column tube. The upper steering shaft and the lower steering shaft are connected by splines. The upper mounting bracket is welded to the middle part of the upper column tube, and the lower mounting bracket is welded to the lower column tube. The lower steering shaft is a columnar structure with large diameters at both ends and a small diameter in the middle. A plurality of metal shrapnel are welded axially and circumferentially at the shaft end with a small diameter in the middle of the lower steering shaft. The circumference of the shrapnel is higher than the large-diameter parts at both ends of the lower steering shaft. Spline grooves are provided at both large-diameter parts at both ends of the lower steering shaft. Not only does the steering column have good energy absorption effect, but it can also continue to steer after collapse, and the mounting bracket can also absorb part of the energy after a collision.

[0003] Since the common automobile steering column assembly is welded to its mounting bracket as a whole, when one of them is damaged, it needs to be replaced as a whole, resulting in unnecessary waste, thus causing the problem that it is more wasteful of materials to replace the conventional automobile steering column assembly after damage.

[0004] Therefore, we propose a steering column mounting bracket and a steering column assembly to solve the above problems. Content of the Utility Model

When it is necessary to disassemble the steering column assembly and the installation bracket, the bolt is unscrewed with the help of a wrench, and then the bolt is removed, so that the installation bracket and the gland are separated, and then the installation bracket and the gland are removed from outside the steering column assembly, which is convenient to replace the steering column assembly, the installation bracket or the gland separately, reducing material waste.

[0008] Preferably, the steering column assembly includes a steering column housing, a buckle, and a steering column. The steering column is rotatably installed inside the steering column housing, and the buckle is fixedly connected to the outside of the steering column housing. The buckle is snapped between the mounting bracket and the gland, then the bolt is passed through the gland, and then the bolt is tightened on the mounting bracket. The bolt is used to lock the mounting bracket and the gland, so that the mounting bracket and the gland clamp and fix the buckle, which is convenient for fixing the steering column assembly, the mounting bracket and the gland.

[0009] Preferably, the steering column assembly further includes an orientation block, and the upper end of the orientation block is fixedly connected to the buckle. By inserting the orientation block into the lower part of the mounting bracket, it is convenient to stabilize the relative angle between the steering column housing and the mounting bracket.

[0010] Preferably, the mounting bracket includes a buckle seat, a threaded seat, and a mounting plate. The threaded seats are symmetrically and fixedly connected to the upper part of the buckle seat, and the mounting plate is fixedly connected to the lower end of the buckle seat. After the bolt passes through the gland and is screwed into the threaded seat, and the bolt is tightened, it is convenient to make the bolt press and fix the gland.

[0011] Preferably, the mounting bracket further includes a reinforcement plate, and the reinforcement plate is fixedly connected between the buckle seat and the threaded seat. The reinforcement plate is used to increase the firmness between the threaded seat and the buckle seat.

[0012] Preferably, the gland includes a gland body and mounting ears. The mounting ears are symmetrically and fixedly connected to the side of the gland body. After the bolt passes through the mounting ears and is tightened, the bolt presses the mounting ears downward, and the mounting ears act on the gland body downward, which is convenient to clamp and fix the steering column assembly between the gland body and the mounting bracket.

[0013] Preferably, the gland further includes a reinforcement strip, and the reinforcement strip is fixedly connected to the upper part of the gland body. The reinforcement strip is used to increase the stability of the gland body structure.

[0014] In summary, the technical effects and advantages of the present utility model are as follows:

[0015] 1. When it is necessary to disassemble the steering column assembly and the mounting bracket, the bolt is unscrewed with the help of a wrench, and then the bolt is removed, so that the mounting bracket and the gland are separated, and then the mounting bracket and the gland are removed from outside the steering column assembly, which is convenient for separately replacing the steering column assembly, the mounting bracket or the gland, and reduces material waste.

[0016] 2. The buckle is snapped between the mounting bracket and the gland, then the bolt is passed through the gland, and then the bolt is tightened on the mounting bracket. The bolt is used to lock the mounting bracket and the gland, so that the mounting bracket and the gland clamp and fix the buckle, which is convenient for fixing the steering column assembly, the mounting bracket and the gland.
