Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of vehicle pedal components, and in particular to a pedal base suitable for brake pedals. Background Technology
[0002] In the automotive industry chain, pedals are an indispensable component of automobiles. The traditional pedal structure usually consists of four parts: a left bracket, a right bracket, a connecting bracket, and an upper mounting bracket, which are welded together to form a pedal base. The left and right brackets each have two mounting holes, and the upper mounting bracket has an upper mounting hole. The upper mounting bracket is fixedly connected to the left and right brackets to ensure the overall strength of the pedal base. These five mounting holes enable the connection between the vehicle body panel and the pedal base.
[0003] Because the pedal base requires four parts to assemble, the large number of parts results in more production processes, a heavier assembly, and higher production costs. Utility Model Content
[0004] The present invention aims to provide a pedal base suitable for brake pedals, so as to reduce the number of parts required to assemble the pedal base while ensuring the overall strength of the pedal base, thereby reducing the production process, reducing the overall weight of the assembly and reducing the production cost.
[0005] Therefore, the technical solution adopted by this utility model is as follows: a pedal base suitable for a brake pedal, including a left bracket, a right bracket, and a connecting bracket, wherein the connecting bracket is fixedly connected to the left bracket and the right bracket, and both the left bracket and the right bracket are provided with a pivot hole; the left bracket includes a left side plate and a left mounting plate, and the right bracket includes a right side plate and a right mounting plate; the left end of the left mounting plate is fixedly connected to the left side plate, and the top end is fixedly provided with a first left bend, the top end of the first left bend is fixedly provided with a first left flange, the left end of the first left flange is fixedly provided with a second left bend, the bottom end of the second left bend is fixedly provided with a second left flange, and the second left flange is fixedly connected to... The left side plate; the right mounting plate is fixedly connected to the right side plate at its right end, and a first right bend is fixedly provided at its top end. A first right flange is fixedly provided at the top end of the first right bend, a second right bend is fixedly provided at the right end of the first right flange, and a second right flange is fixedly provided at the bottom end of the second right bend. The second right flange is fixedly connected to the right side plate; the first left flange is fixedly connected to the first right flange, and the left mounting plate is fixedly connected to the right mounting plate. Both the left and right mounting plates are provided with upper mounting holes, and a first left mounting hole, a second left mounting hole, a first right mounting hole, and a second right mounting hole are provided respectively. The two upper mounting holes on the left and right mounting plates overlap.
[0006] As a preferred embodiment of the above solution, a left convex bulge and a right convex bulge are fixedly provided on the left side plate and the right side plate, respectively. The height of the left convex bulge and the right convex bulge are both 3.5mm, and the forming root is provided with a rounded corner with a radius of 2mm.
[0007] More preferably, both the left and right convex bulges are provided with weight-reducing holes, and the minimum distance between the weight-reducing holes and the edge of the convex bulges they are located on is 2 to 3 mm.
[0008] More preferably, a left outer reinforcing rib and a left inner reinforcing rib are fixedly provided at the connection between the left side plate and the left mounting plate, and the angle of the left outer reinforcing rib and the left inner reinforcing rib are both 90 degrees and the depth is both 6.3 mm.
[0009] More preferably, a right outer reinforcing rib and a right inner reinforcing rib are fixedly provided at the connection between the right side plate and the right mounting plate, and the angle of the right outer reinforcing rib and the right inner reinforcing rib are both 90 degrees and the depth is both 6.3 mm.
[0010] More preferably, a third left flange is fixedly provided at the end of the left side plate away from the left mounting plate, and the width of the third left flange is 7-8mm.
[0011] More preferably, a third right flange is fixedly provided at the end of the right side plate away from the right mounting plate, and the width of the third right flange is 7-8mm.
[0012] The beneficial effects of this utility model are as follows: upper mounting holes are opened on the left and right mounting plates, and the upper mounting bracket is replaced by the first left flange, the second left flange, the first right flange, and the second right flange formed by stamping and bending the left and right mounting plates respectively. This allows the pedal base to have 5 mounting holes while ensuring the overall strength of the pedal base. The pedal base only needs to be composed of 3 parts: the left bracket, the right bracket, and the connecting bracket. This reduces the number of parts and production steps in the pedal base, and lowers the overall weight and production cost. Attached Figure Description

The two upper mounting holes 11 on the left mounting plate 24 and the right mounting plate 25 overlap.
[0023] The fixed connections between the first left flange 5 and the first right flange 8, between the second left flange 7 and the left side plate 26, between the second right flange 10 and the right side plate 29, and between the left mounting plate 24 and the right mounting plate 25 are all welded. After the left mounting plate 24 and the right mounting plate 25 are welded together, a double-layer structure can be formed to increase the strength of the base. The pedal arm 18 of the brake pedal is connected to the rotating shaft 16, which is installed in two rotating shaft holes 23, thereby realizing the connection between the brake pedal and the pedal base. This is existing technology and will not be described in detail here. The widths of the first left flange 5, the second left flange 7, the first right flange 8, and the second right flange 10 are all 14-25 mm.
[0024] Left convex 2 and right convex 13 are fixedly provided on the left side plate 26 and right side plate 29 respectively. The height of left convex 2 and right convex 13 is 3.5mm, and the forming root is provided with a rounded corner with a radius of 2mm.
[0025] The left convex bulge 2 and the right convex bulge 13 can increase the strength of the base and help to disperse stress. The shape should be as large as possible. It is recommended that the minimum distance between the left convex bulge 2 and the periphery of the left side plate 26 be 10-20mm, and the minimum distance between the right convex bulge 13 and the periphery of the right side plate 29 be 10-20mm.

The angles of the right outer reinforcing rib 32 and the right inner reinforcing rib 12 are both 90 degrees, and the depth of each is 6.3 mm.
[0029] The left outer reinforcing rib 3, left inner reinforcing rib 31, right outer reinforcing rib 32, and right inner reinforcing rib 12 can increase the strength of the entire pedal base and help to disperse stress. The positions of the left outer reinforcing rib 3, left inner reinforcing rib 31, right outer reinforcing rib 32, and right inner reinforcing rib 12 must be ensured so as not to affect the welding of the flange.
