Description

Technical Field

[0001] The utility model relates to the technical field of automobile shifting equipment, in particular to a fixing bracket for a speed change operating mechanism. Background Art

[0002] The speed shift mechanism is a crucial component of a vehicle's transmission system. Its primary function is to allow the driver to shift the transmission into the appropriate gear as needed. While the design and construction of the speed shift mechanism vary depending on the vehicle type, the underlying principles remain similar. A mounting bracket secures the speed shift mechanism to the vehicle chassis. Existing mounting brackets are either bolted directly to the chassis or welded integrally to the chassis after the speed shift mechanism is installed. This results in the shift lever's mounting position and height being unadjustable, and can easily interfere with other vehicle components when the shift lever is operated. Summary of the Invention

[0003] In order to solve the problem that the installation position and height of the shift lever of the existing speed shift control mechanism cannot be adjusted, the utility model proposes a fixed bracket for the speed shift control mechanism, wherein the front and rear position of the base plate relative to the floor frame is adjustable, and the left and right position of the second bracket body relative to the first bracket body is adjustable to achieve adjustment of the front and rear, left and right positions of the fixed bracket, and the first bracket body is retractable to adjust the height of the fixed bracket, thereby avoiding positional interference between the shift lever and other components in the car during operation.

[0004] In order to achieve the above purpose, the technical solution of the utility model is:

[0005] A fixed bracket for a speed shift mechanism, used for mounting a speed shift mechanism assembly, is disposed on a floor frame and includes a base plate, a first bracket body, a second bracket body, and a mounting seat. The first bracket body is fixed to the base plate, the second bracket body is disposed on the first bracket body, and the mounting seat is fixed to a side of the second bracket body away from the first bracket body and is used for mounting the speed shift mechanism assembly. The base plate is adjustable in front-to-back position relative to the floor frame, the second bracket body is adjustable in left-to-right position relative to the first bracket body, and the first bracket body is telescopic. The telescopic configuration of the first bracket body allows the fixed bracket to accommodate vehicles of different heights, such as cars and trucks.

[0006] Furthermore, the base plate is provided with a plurality of symmetrically arranged first strip holes, the floor frame is provided with a first fixing hole, and first bolts are passed through the first strip holes and the first fixing holes in sequence to realize the connection and fixation between the base plate and the floor frame, and the front and rear positions of the first bolts in the first strip holes are adjustable.

[0007] Furthermore, the second bracket body is symmetrically provided with a plurality of second strip-shaped holes on both sides, the first bracket body is provided with second fixing holes that match the second strip-shaped holes, and second bolts are sequentially passed through the second strip-shaped holes and the second fixing holes to achieve the connection and fixation between the second bracket body and the first bracket body, and the left and right positions of the second bolts in the second strip-shaped holes are adjustable. The first bracket body is in an inverted "L" shape.

[0008] Furthermore, a fastening bolt is screwed onto one side of the second bracket body, and the fastening bolt passes through the second bracket body and contacts the side surface of the first bracket body, thereby improving the stability of the second bracket body on the first bracket body and preventing the second bracket body from loosening on the first bracket body after repeated operation of the shift lever.

[0009] Furthermore, the first bracket body includes an outer cylinder and an inner cylinder, the inner cylinder is slidably arranged inside the outer cylinder and contacts the inner side wall of the outer cylinder, a slide groove is provided on the inner cylinder, and a tightening bolt is screwed on one side of the outer cylinder, and the tightening bolt passes through the outer cylinder and extends into the slide groove and contacts the side wall of the slide groove.

[0010] Furthermore, the mounting seat is fixed obliquely on the side of the second bracket body away from the first bracket body. The mounting seat is in a "Z" shape, including mounting parts at the upper and lower ends and a connecting part connecting the two mounting parts. The mounting part is bolted and fixed to the speed control mechanism assembly.

[0011] Furthermore, a pad is provided between the bottom plate and the floor frame to improve the fastening of the connection between the bottom plate and the floor frame.

[0012] Through the above technical solution, the beneficial effects of the present invention are as follows: in the present invention, the first bolt is loosened, the base plate is moved forward and backward, and the position of the first bolt in the first strip hole can be changed to adjust the front and rear position of the base plate; the second bolt is loosened and the second bracket body is moved left and right; the second bracket body is moved left and right, and the position of the second bolt on the second strip hole can be changed to adjust the front and rear position of the second bracket body, thereby realizing the adjustment of the front and rear left and right positions of the fixed bracket, avoiding the position interference of the shift lever with other components in the car during operation; at the same time, the telescopic setting of the first bracket body enables the fixed bracket to adapt to models of different heights, such as cars and trucks, thereby increasing the applicable scenarios of the device.
