[0001] The utility model relates to the technical field of automobile hydraulic brake valves, in particular to an automobile brake valve assembly. Background Art

[0002] Automotive brake valves are divided into pneumatic brake valves and hydraulic brake valves. The proper functioning of brake valves is crucial for parking, providing technical support for smooth braking. The continued development of this technology is crucial for both automotive manufacturing and road traffic safety.

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide an automobile brake valve assembly. Through the provision of a baffle and a contact sensor, when the pedal rotates around the pin shaft and is pressed downward to the end of the stroke, the baffle on the lower side of the pedal contacts the contact sensor, and the contact sensor detects the signal that the pedal is pressed down to the end of the stroke, so that the operator is promptly reminded, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an automobile brake valve assembly, comprising a fixed plate, a valve body being passed through the fixed plate, a piston top being provided at the upper end of the valve body, a limiting collar being connected to the upper end of the piston top, a pedal being provided on the upper side of the limiting collar, one end of the pedal being hinged to the fixed plate, a baffle being installed on the lower side of the other end of the pedal, and a contact sensor being provided on the lower side of the baffle.

[0006] Furthermore, an anti-slip protrusion is provided on the upper side of the pedal. Two pins are passed through the pedal, and a connecting rod is connected to the same end of the two pins.

[0007] Furthermore, the pin shaft at the lower part of the pedal is connected to a support block fixedly arranged on the fixed plate, and a brake oil hole is provided on one side of the valve body.

[0008] Furthermore, a pressure oil hole is provided on the lower side of the brake oil hole, and a tank oil hole is provided on one side of the pressure oil hole.

[0009] Furthermore, the anti-slip protrusion and the pedal are integrally formed, and the contact sensor and the fixing plate are connected by bolts.

[0010] Furthermore, the support block is welded to the fixing plate, and the valve body is connected to the fixing plate via bolts.

[0011] Furthermore, the top end of the piston is rotatably connected to the limiting collar.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This utility model provides a baffle and a contact sensor. When the pedal rotates around the pin shaft and is pressed down to the end of the stroke, the baffle on the lower side of the pedal contacts the contact sensor. The contact sensor detects the signal that the pedal is pressed down to the end of the stroke, so that the operator is promptly reminded. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-3 This embodiment provides a technical solution: an automobile brake valve assembly, including a fixed plate 2, a valve body 3 is passed through the fixed plate 2, a piston top 8 is provided on the upper end of the valve body 3, a limit collar 10 is connected to the upper end of the piston top 8, a pedal 1 is provided on the upper side of the limit collar 10, one end of the pedal 1 is hinged to the fixed plate 2, a baffle 12 is installed on the lower side of the other end of the pedal 1, and a contact sensor 13 is provided on the lower side of the baffle 12.

[0020] like Figure 1-3As shown, the valve body 3 is connected to the hydraulic oil pipeline and the brake module. When braking is needed, the operator steps on the pedal 1, causing the pedal 1 to rotate downward around the pin shaft 7, so that the lower side of the pedal 1 pushes the piston top 8 downward through the limiting collar 10, so that the structure inside the valve body 3 moves, and the brake oil hole 4 is connected to the pressure oil hole 6, so that the pressure oil enters the pipeline, thereby driving the brake module to brake the wheel. When the pedal 1 is not stepped on, the spring return mechanism inside the valve body 3 causes the piston top 8 to move upward, thereby returning the pedal 1 to its original position, so that the brake oil hole 4 is connected to the oil tank oil hole 5, and the brake oil hole 4 is disconnected from the pressure oil hole 6. When the pedal 1 is pressed down to the end of the stroke, the contact sensor 13 is pressed by the baffle 12, so that the contact sensor 13 detects the signal of the pedal, so that the operator can be reminded in time.

[0021] An anti-slip protrusion 9 is provided on the upper side of the pedal 1 , and two pins 7 are passed through the pedal 1 , and a connecting rod 11 is connected to the same end of the two pins 7 .

[0022] The pin shaft 7 at the lower part of the pedal 1 is connected to the support block 14 fixedly arranged on the fixed plate 2 , and a brake oil hole 4 is provided on one side of the valve body 3 .

[0023] A pressure oil hole 6 is provided on the lower side of the brake oil hole 4 , and a tank oil hole 5 is provided on one side of the pressure oil hole 6 .

[0024] The anti-slip protrusion 9 is integrally formed with the pedal 1 , and the contact sensor 13 is connected to the fixing plate 2 via bolts.

[0025] The support block 14 is welded to the fixing plate 2, and the valve body 3 is connected to the fixing plate 2 by bolts.

[0026] The piston top 8 is rotatably connected to the limiting collar 10 .

[0027] The working principle of the automobile brake valve assembly provided by the utility model is as follows: Figure 1-Figure 3 As shown, the valve body 3 is connected to the hydraulic oil pipeline and the brake module. When braking is needed, the operator steps on the pedal 1, causing the pedal 1 to rotate downward around the pin shaft 7, so that the lower side of the pedal 1 pushes the piston top 8 downward through the limiting collar 10, so that the structure inside the valve body 3 moves, and the brake oil hole 4 is connected to the pressure oil hole 6, so that the pressure oil enters the pipeline, thereby driving the brake module to brake the wheel. When the pedal 1 is not stepped on, the spring return mechanism inside the valve body 3 causes the piston top 8 to move upward, thereby returning the pedal 1 to its original position, so that the brake oil hole 4 is connected to the oil tank oil hole 5, and the brake oil hole 4 is disconnected from the pressure oil hole 6. When the pedal 1 is pressed down to the end of the stroke, the contact sensor 13 is pressed by the baffle 12, so that the contact sensor 13 detects the signal of the pedal, so that the operator can be reminded in time.
