[0033] like Figures 1 to 6 The installation mechanism of a hand brake valve shown in the figure comprises a parking brake reinforcement plate 1 and a mounting bracket 3. The parking brake reinforcement plate 1 is fitted to the vehicle body floor 2, and the fitting part of the parking brake reinforcement plate 1 and the vehicle body floor 2 is irregularly bent. A first mounting hole is provided on the parking brake reinforcement plate 1. A second mounting hole 31 matching with the first mounting hole is provided at the bottom of the mounting bracket 3, and a fastening bolt 32 passes through the first mounting hole and the second mounting hole 31, so as to realize the installation and fixation of the mounting bracket 3 and the parking brake reinforcement plate 1, and improve the connection stability of the mounting bracket 3. The mounting bracket 3 includes an integrally formed first Z-shaped plate 33, a second Z-shaped plate 34, and a connecting plate 35 connecting the first Z-shaped plate 33 and the second Z-shaped plate 34. A notch 36 that half-wraps the hand brake valve 5 is formed between the first Z-shaped plate 33, the second Z-shaped plate 34, and the connecting plate 35. A third mounting hole 37 that cooperates with the hand brake valve 5 is provided above the first Z-shaped plate 33 and the second Z-shaped plate 34.

A weight-reducing hole 38 is also provided on the first Z-shaped plate 33, which reduces the weight of the mounting bracket 3 and can ensure the supporting strength of the mounting bracket 3.

[0034] In one embodiment, during installation, the parking brake reinforcement plate 1 is firstly attached to the vehicle body floor 2, and then the parking brake reinforcement plate 1 is fixed to the vehicle body floor 2. Since the parking brake reinforcement plate 1 and the vehicle body floor 2 cooperate with each other and are both irregular in shape, it is difficult for the parking brake reinforcement plate 1 to slip relative to the vehicle body floor 2, thereby increasing the firmness of the connection between the parking brake reinforcement plate 1 and the vehicle body floor 2. Then, the mounting bracket 3 is placed on the parking brake reinforcement plate 1, and after the fastening bolt 32 passes through the first mounting hole and the second mounting hole 31, the fastening nut is used to lock the fastening bolt 32, thereby achieving bolt fixation of the mounting bracket 3 and the parking brake reinforcement plate 1. The hand brake valve 5 is installed on the mounting bracket 3 by bolts, specifically, the hand brake valve 5 is installed to the third mounting hole 37 of the mounting bracket 3. Finally, the parking brake decorative cover 4 is installed to the outer side of the parking brake reinforcement plate 1 to complete the assembly of the mounting mechanism.

[0035] It should be noted that the mounting bracket 3 uses a first Z-shaped plate 33 and a second Z-shaped plate 34 that are perpendicular to each other, which can increase the contact area between the mounting bracket 3 and the parking brake reinforcement plate 1 and between the mounting bracket 3 and the hand brake valve 5, and further improve the installation stability of the mounting bracket 3.

[0036] Preferably, the width of the first Z-shaped plate 33 is greater than the width of the second Z-shaped plate 34 , and the side edge of the second Z-shaped plate 34 is folded to form a reinforcing arc edge 341 , thereby improving the supporting strength of the second Z-shaped plate 34 .

[0037] In one embodiment, the mounting mechanism can be applied to a light truck. According to the space configuration of the vehicle, the width of the second Z-shaped plate 34 can be appropriately reduced. In order to ensure the supporting strength of the reduced second Z-shaped plate 34, the side edge of the second support plate is folded to form a reinforcing arc edge 341 to improve the supporting performance of the second Z-shaped plate 34.

[0038] Preferably, a brake air pipe fixing plate 331 is formed on the side of the first Z-shaped plate 33, and a through hole 332 is provided on the brake air pipe fixing plate 331 to facilitate installation and fixing of the brake air pipe. It should be noted that the number and diameter of the through holes 332 can be provided according to the configuration of the brake air pipe actually used.

[0039] Preferably, the parking brake reinforcement plate 1 is welded and fixed to the vehicle body floor 2, and the welding method is adopted to improve the stability of the connection between the parking brake reinforcement plate 1 and the vehicle body floor 2, and strengthen the supporting capacity of the parking brake reinforcement plate 1 and the vehicle body floor 2.

[0040] Preferably, a projection-welded nut or projection-welded bolt is provided on the parking brake reinforcement plate 1 to facilitate installation of the mounting bracket 3 on the parking brake reinforcement plate 1 .

[0041] In one embodiment, a projection weld nut is welded on the parking brake reinforcement plate 1 , and the fastening bolt 32 passes through the second mounting hole 31 and the first mounting hole and is screwed into the projection weld nut to achieve connection and fixation between the parking brake reinforcement plate 1 and the mounting bracket 3 .

[0042] In one embodiment, a projection welding bolt is welded on the parking brake reinforcement plate 1, and the projection welding bolt passes through the first mounting hole. When assembling the mounting bracket 3, the mounting bracket 3 is placed on the parking brake reinforcement plate 1, and the second mounting hole 31 is sleeved on the projection welding bolt, and then the nut is screwed onto the projection welding bolt to achieve the connection and fixation of the parking brake reinforcement plate 1 and the mounting bracket 3.

[0043] Preferably, the connecting plate 35 is an arc-shaped plate, and the connecting plate 35 is flush with the upper bending portion of the first Z-shaped plate 33 , thereby ensuring the supporting strength of the entire mounting bracket 3 .

[0044] Preferably, the number of the third mounting holes 37 is at least two, so as to achieve the installation and fixation of the hand brake valve 5 .

[0045] Preferably, the mounting mechanism also includes a parking brake decorative cover 4, which is mounted to the parking brake reinforcement plate 1, and the parking brake decorative cover 4 shields the mounting bracket 3, thereby improving the aesthetics of the mounting mechanism and preventing foreign debris from falling into the connection of the hand brake valve 5 and affecting driving safety.

[0046] Preferably, arc-shaped folding edges 381 are provided around the weight-reducing holes 38 to reduce the reduction in the supporting performance of the first Z-shaped plate 33 caused by the weight-reducing holes 38 .

[0047] When the above-mentioned installation mechanism of the hand brake valve is adopted, the problem of spatial arrangement and installation of the vehicle hand brake valve 5 is solved, and the parking brake function of the product is ensured. The installation stability of the mounting bracket 3 is improved by installing the parking brake reinforcement plate 1 between the mounting bracket 3 and the vehicle body floor 2.
