Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle braking detection, and particularly relates to an auxiliary measuring device for vehicle braking deviation test. Background Technique

[0002] With the rapid development of the automotive industry, the safety performance of vehicles has attracted more and more attention. Among them, the stability and reliability of the braking system are one of the key factors to ensure driving safety. As one of the common problems of the braking system, braking deviation not only affects the driving experience but also seriously threatens road traffic safety. Braking deviation usually means that during braking, the vehicle cannot maintain a straight line but deviates to one side, which is often caused by uneven braking forces on both sides of the braking system, inaccurate wheel alignment, or abnormal suspension systems.

[0003] In order to accurately detect and evaluate the braking deviation of vehicles, traditional test devices mostly use a variety of sensors combined with corresponding software for testing. Although these test devices can reflect the braking performance to a certain extent, they have limitations such as difficult-to-control test environments and susceptibility to external interference of test data. In addition, some existing braking deviation test devices have complex structures and cumbersome operations, requiring professional personnel to operate. Content of the Utility Model

[0004] The purpose of the utility model is to provide an auxiliary measuring device for vehicle braking deviation test to solve the problems existing in the prior art in view of the defects existing in the prior art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An auxiliary measuring device for vehicle braking deviation test, comprising a braking detection element, an electric pump power switch, an electric pump, a pigment storage barrel, a pigment spray head, a pigment transport pipe, a spray head mounting bracket, and a power supply for powering the entire device;

[0007] The pigment spray head is installed at the front end of the vehicle through the spray head mounting bracket, the output end of the pigment spray head faces the ground, and the other end of the pigment spray head is connected to the output end of the electric pump through the pigment transport pipe, and the input end of the electric pump is connected to the pigment storage barrel;

[0009] A further improvement of this technical solution is that the nozzle mounting bracket includes a nozzle support and a rubber pressing block. The nozzle support is provided with a number of mounting holes, and the nozzle support can be fixed at the center of the front end of the vehicle through a fixing member passing through the mounting holes. The rubber pressing block is mounted on the side of the nozzle support close to the vehicle, and a transport pipe mounting hole is provided on the rubber pressing block. After the pigment transport pipe passes through the transport pipe mounting hole, it is connected to a pigment nozzle fixed on the nozzle support.

[0010] A further improvement of this technical solution is that the nozzle support adopts a U-shaped nozzle support, and the rubber pressing block is mounted in the U-shaped groove of the U-shaped mounting bracket.

[0011] A further improvement of this technical solution is that the nozzle mounting bracket further includes a knob, which is mounted on the side of the nozzle support away from the rubber pressing block. The knob passes through the nozzle support and is connected to the pigment transport pipe.

[0012] A further improvement of this technical solution is that the braking detection element adopts a pressure sensor.

[0013] A further improvement of this technical solution is that the input end of the electric pump and the pigment storage barrel are fixed together by bolts and sealing washers, and the pigment storage barrel is inverted on the vehicle.

[0014] The beneficial effects of this utility model are as follows:

[0015] Intuitive and immediate feedback: By spraying pigment on the ground through the pigment nozzle when the vehicle brakes, the braking trajectory of the vehicle can be intuitively left on the road surface, immediately reflecting whether there is a phenomenon of braking deviation of the vehicle.

[0016] Strong adaptability to the test environment: Compared with the test device relying on precise sensors, this device is less affected by the external environment (such as road surface material, humidity, temperature, etc.).

[0017] Simple operation and reduced labor cost: The device structure is relatively simple, easy to install and disassemble, and does not require a complex debugging process. At the same time, its operation is also simpler and can be carried out without professional personnel, greatly reducing the labor cost and time cost of the test.

[0018] High cost-effectiveness: Due to the adoption of a relatively simple mechanical and electrical structure and common pigments as the test medium, the production cost and maintenance cost of this device are relatively low.

[0019] In addition, the design principle of this utility model is reliable, the structure is simple, and it has a very wide application prospect.

[0027] In order to facilitate the electric pump to draw the pigment, the input end of the electric pump and the pigment storage barrel are fixed together by bolts and sealing washers, and the pigment storage barrel is inverted on the vehicle.

[0028] AsFigure 3 As shown in the figure, the nozzle mounting bracket includes a nozzle support and a rubber pressing block. The nozzle support is provided with a number of mounting holes, and the nozzle support can be fixed at the center of the front end of the vehicle through fixing parts (such as cable ties or bolts and nuts) passing through the mounting holes.

The knob passes through the nozzle support and is then connected to the pigment transport pipe.

[0031] The working principle of the present utility model is as follows: The pressure sensor detects the signal of the driver stepping on the brake pedal, transmits an electrical signal to the power switch of the electric pump, forms a power supply path, and supplies power to the electric pump; after the electric pump is powered on, it sucks the pigment in the pigment storage barrel and evenly sprays it on the road surface where the vehicle is traveling through the pigment nozzle. The staff can assist in measuring the vehicle deviation state by observing the spraying position of the pigment on the ground.
