Among them, the hydraulic control unit is the core component of the entire brake system, providing the brake system with pressure building, pressure maintenance, pressure reduction and fluid replenishment functions; and the function of the fluid reservoir in the hydraulic control unit to provide the system with fluid storage and fluid supply should not be underestimated. Different models have different boundary conditions and braking requirements, so they naturally have different requirements for fluid reservoirs. The development cycle from design to actual installation and use is long. During this period, the functional verification of the fluid reservoir under different working conditions of the vehicle is particularly important.

[0004] Most of the existing test equipment uses the centrifugal effect of the centrifuge to simulate the corresponding liquid level state of the liquid storage pot under different working conditions of the vehicle. Because of the centrifugal action, most of these devices are huge in size and require high-power motors to provide power.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0036] See also Figure 1-13 The present invention provides a technical solution: an efficient multi-condition performance test device for a liquid storage pot, comprising:

[0037] The mounting base plate 1 is fixed to the accelerator to test the performance of the liquid storage pot 4 under different working conditions;

[0038] Also includes:

[0039] An observation component 2 is arranged on the surface of the mounting base plate 1. The observation component 2 can directly observe the multi-condition performance test data of the liquid storage pot 4 with naked eyes. The operation is simple and convenient, and the observation component 2 can also cooperate with various external sensors to obtain a data table.

[0040] Test component 3, test component 3 is arranged on the side of observation component 2, and the flow of liquid in the liquid storage pot 4 on observation component 2 provides power for the operation of test component 3. Test component 3 can obtain the maximum and minimum values ​​of the deflection angle of the liquid in the liquid storage pot 4 in the multi-functional working condition performance test of the liquid storage pot 4, which is convenient for subsequent operators to evaluate the experimental data.

[0041] The observation component 2 includes two identical support plates 201, which are used to fix the rotation of the supporting shaft 202. The surface of the support plate 201 is slidably connected with the rotating shaft 202. The rotating shaft 202 adopts a high-precision rotating shaft. When the experimenter rotates the rotating shaft 202, the support plate 201 can control and lock the rotating shaft 202, so as to facilitate the adjustment of the target slope scale, that is, the value on the scale 204. The surface of the rotating shaft 202 is fixedly connected with a connecting bracket 203, which is used to be connected to the tooling bracket 207 through the rotating shaft 205.

[0042] The surface of the support plate 201 is provided with a scale 1 204. When the rotating shaft 1 202 rotates, the value on the scale 1 204 indicates the size of the target slope scale. The surface of the connecting bracket 203 is slidably connected with the rotating shaft 205. The rotating shaft 205 also adopts a high-precision rotating shaft. When the experimenter rotates the rotating shaft 205, the connecting bracket 203 can control and lock the rotating shaft 205, so as to facilitate the adjustment of the target steering acceleration scale, that is, the value on the scale 206.

[0045] The test assembly 3 includes eight identical spheres 1 301, which are used to drive the connecting rod 302 to rise and fall. The surfaces of the eight spheres 1 301 are fixedly connected with the connecting rod 302, and the connecting rod 302 is L-shaped. The rise and fall of the connecting rod 302 can drive the rise and fall of the sphere 2 303. The surface of the connecting rod 302 is fixedly connected with the sphere 2 303, and the rise and fall of the sphere 2 303 can drive the rise and fall of the hemispherical magnetic shell 1 305. The surface of the connecting rod 302 is slidably connected with a fixing plate 304, which is used to fix the position of the connecting rod 302 in the liquid storage pot 4 to prevent the impact force of the liquid in the liquid storage pot 4 during the test from affecting the position of the connecting rod 302.

[0046] The surface of the sphere 2 303 is fixedly connected to the hemispherical magnetic shell 1 305, and the surface of the hemispherical magnetic shell 1 305 is movably connected to the hemispherical magnetic shell 2 306. There is a weak magnetic force of mutual attraction between the hemispherical magnetic shell 1 305 and the hemispherical magnetic shell 2 306, so that the hemispherical magnetic shell 1 305 can drive the movement of the hemispherical magnetic shell 2 306 during the rising and falling process, thereby driving the rising and falling of the hollow column 307. The surface of the hemispherical magnetic shell 2 306 is fixedly connected to the hollow column 307, and a plurality of identical arc grooves 308 are provided on the surface of the hollow column 307. There is a cover in the internal structure of the hollow column 307, which covers the surface of the light bar 2 325 and the sensing column 2 324, and is used to make the sensor 2 326 sense a lightless state in the initial state.

[0047] The surface of the mounting base 1 is fixedly connected with a track 309 to facilitate the sliding of the slide rail 310. The surface of the track 309 is slidably connected with the slide rail 310. The surface of the slide rail 310 is fixedly connected with a driver 311. The surface of the slide rail 310 is fixedly connected with a test box 312. The driver 311 drives the slide rail 310 to slide, and the slide rail 310 can drive the test box 312 to move left and right. The surface of the test box 312 is fixedly connected with a spacer 313 for controlling the position of the connecting rod 302 in the test box 312 to prevent the front and rear spaced connecting rods 302 from colliding, thereby affecting the experimental results. The surface of the liquid storage pot 4 is fixedly connected with a laser sensor 314 for sensing the changes in the liquid level in the liquid storage pot 4 and converting the optical signal into an electrical signal to control the movement of the driver 311.

[0048] The surface of the test box 312 is fixedly connected with a support bar 315 for fixing the support base 1 316 and the base 2 318. The surface of the support bar 315 is fixedly connected with the base 1 316 for fixing the movement of the support block 1 317. The surface of the base 1 316 is slidably connected with the block 1 317. During the movement, due to the existence of acceleration and the inertia of the object itself, the block 1 317 supports the hollow column 307 that rises or falls during forward acceleration and reverse deceleration to prevent the hollow column 307 from falling from the highest point of the movement or continuing to fall to the lowest point. The support plate 201 The surface is fixedly connected with a base 2 318 for fixing the movement of a supporting block 2 319. The surface of the base 2 318 is slidably connected with a supporting block 2 319. The supporting block 2 319 supports the hollow column 307 that rises or falls during reverse acceleration and forward deceleration to prevent the hollow column 307 from falling from the highest point or from continuing to fall to the lowest point. Regardless of forward acceleration and reverse deceleration or forward deceleration or reverse acceleration, the angle between the liquid surface in the liquid storage pot 4 and the horizontal plane will have a maximum value and a minimum value. The deflection of the liquid surface in the liquid storage pot 4 cannot completely deflect the laser in the laser sensor 314. When the test device is in the liquid surface, when it changes from forward acceleration or reverse deceleration to forward deceleration or reverse acceleration, the liquid surface inclination angle in the liquid storage pot 4 changes from maximum to minimum, and the fluctuation of the liquid surface will bring the ball 301 to float up or down in the liquid storage pot 4. At this time, the ball 301 will drive the connecting rod 302 to rise or fall, and the rise or fall of the connecting rod 302 will drive the hollow column 307 to rise or fall. At this time, the hollow column 307 rises to the highest point and is still fixed by the fixing block 317 until the liquid surface is level with the horizontal plane. At this time, the laser in the laser sensor 314 is completely in the liquid. In the surface, the optical signal is converted into an electrical signal, and the control driver 311 drives the movement of the test box 312. The liquid surface tilts in the opposite direction. The fluctuation of the liquid surface will cause the ball 1 301 to float up or down in the liquid storage pot 4. At this time, the ball 1 301 will drive the connecting rod 302 to rise or fall, and the rise or fall of the connecting rod 302 will drive the hollow column 307 to rise or fall. At this time, the hollow column 307 rises to the highest point and is fixed by the fixing block 2 319. The liquid surface keeps changing and keeps level. This process will be repeated, thereby obtaining a set of comparative data for reference by the experimenters.

[0049] The surface of the test box 312 is slidably connected to a sensing base 320 for transmitting optically generated data to the mobile platform of the staff. The surface of the sensing base 320 is fixedly connected to a sensing column 321 for sensing the descending distance of the hollow column 307. The surface of the sensing column 321 is fixedly connected to a light bar 322. The surface of the sensing base 320 is fixedly connected to a sensor 323. When the light bar 322 is continuously lit, the sensor cannot sense the data generated by the shadow in the dark. When the hollow column 307 continues to fall and covers the surfaces of the sensing column 321 and the light bar 322, the sensor 323 transmits the value of the sensed shadow area to the mobile end of the experimenter through the sensing base 320 to record the minimum value of the liquid surface inclination. The surface of the sensing column 321 is fixedly connected to A second sensing column 324 is connected to sense the rising distance of the hollow column 307. A second light bar 325 is fixedly connected to the surface of the second sensing column 324. At the beginning, the second light bar 325 is covered by a cover and is in a dark state. A second sensor 326 is fixedly connected to the surface of the sensing base 320. The second sensor 326 can only sense the conditions around the second sensing column 324. When the hollow column 307 rises, the second sensor 326 transmits the value of the sensed bright area to the mobile end of the experimenter through the sensing base 320, records the maximum value of the liquid surface inclination, and obtains the maximum and minimum values ​​of the liquid deflection angle in the liquid storage pot 4 according to the change of the liquid level, so as to facilitate the subsequent evaluation of the experimental data by the operators. By comparing the data under different working conditions, the performance of the liquid storage pot 4 can be more intuitively understood.
