Description

Technical Field

[0001] This invention relates to the field of sensor testing technology, and in particular to a test device for chassis sensors. Background Technology

[0002] With the development of automotive technology, the types and numbers of sensors used on car chassis are increasing. Due to the complex operating environment of vehicles, many sensors used in chassis are exposed to the outside of the vehicle and are easily damaged by the impact of rain, gravel, and temperature changes. Furthermore, the durability assessment of sensors is very important in the early development and later verification of sensors. However, traditional road verification takes a long time and cannot quickly and comprehensively verify the results of gravel impact.

[0003] Currently, most testing equipment on the market has only a single function. If it is necessary to test the durability of chassis sensors under conditions such as rain impact, gravel impact, and temperature changes, each test needs to be conducted individually, which takes a long time and cannot effectively simulate the test results of complex working conditions. There is room for improvement. Summary of the Invention

[0022] The following is for reference. Figures 1-3 The test equipment 100 for the chassis sensor according to an embodiment of the present invention can test the durability of the chassis sensor 1 under various combined working conditions, perform comprehensive verification of the chassis sensor 1, shorten test time, and improve test efficiency.

[0023] like Figure 1 As shown, a chassis sensor test apparatus 100 according to an embodiment of the present invention is used to test a chassis sensor 1, and the test apparatus includes: a test bench 2 and an environmental simulation component 3.

[0024] The test bench 2 is used to support the chassis sensor 1; the environmental simulation component 3 includes at least two of the following: a liquid spray structure 31, a solid spray structure 32, and a temperature control structure 33. The liquid spray structure 31 is used to spray liquid onto the chassis sensor 1, the solid spray structure 32 is used to spray solid particles onto the chassis sensor 1, and the temperature control structure 33 is used to deliver temperature-controlled airflow to the chassis sensor 1.

[0025] Specifically, the chassis sensor test equipment 100 is used to test the durability of the chassis sensor 1. The chassis sensor 1 is installed on the chassis of the vehicle and is susceptible to impacts from rain, gravel, etc., as well as temperature changes. The chassis sensor test equipment 100 can be used to evaluate the durability of the chassis sensor 1 during early development and later verification.

[0026] The chassis sensor test equipment 100 includes a test bench 2 and an environmental simulation component 3. The test bench 2 is used to support the chassis sensor 1. The test bench 2 can be constructed as a plate or a platform to provide a bearing surface, so that the chassis sensor 1 can be placed on the bearing surface and fixed to prevent the chassis sensor 1 from falling and being damaged during the test. The environmental simulation component 3 is used to simulate the working environment of the chassis sensor 1, such as rain impact environment, gravel impact environment, and high and low temperature environment, to test the durability of the chassis sensor 1 under different environments.

[0027] The environmental simulation component 3 includes at least two of the following: a liquid spray structure 31, a solid spray structure 32, and a temperature control structure 33. The liquid spray structure 31 is used to spray liquid onto the chassis sensor 1. The end of the liquid spray structure 31 is set towards the chassis sensor 1 so that the liquid spray structure 31 can spray water or other liquids onto the chassis sensor 1 to simulate the working condition of the chassis sensor 1 being impacted by rainwater. The solid spray structure 32 is used to spray solid particles onto the chassis sensor 1. The end of the solid spray structure 32 is set towards the chassis sensor 1 so that the solid spray structure 32 can spray metal or sand or other solid particles onto the chassis sensor 1 to simulate the working condition of the chassis sensor 1 being impacted by sand or gravel. The temperature control structure 33 is used to deliver temperature-controlled airflow to the chassis sensor 1. The end of the temperature control structure 33 is set towards the chassis sensor 1 so that the temperature control structure 33 can deliver high-temperature or low-temperature airflow to the chassis sensor 1 to simulate the working condition of the chassis sensor 1 in a high-temperature or low-temperature environment.

[0028] The environmental simulation component 3 includes at least two of the following: a liquid spray structure 31, a solid spray structure 32, and a temperature control structure 33. That is, the environmental simulation component 3 may include any two of the following: a liquid spray structure 31, a solid spray structure 32, and a temperature control structure 33, or may include all three: a liquid spray structure 31, a solid spray structure 32, and a temperature control structure 33. This allows the environmental simulation component 3 to simulate various complex working conditions, such as simulating the condition where the chassis sensor 1 is simultaneously subjected to rain and gravel impact, or the condition where the chassis sensor 1 is simultaneously subjected to rain and temperature changes, or the condition where the chassis sensor 1 is simultaneously subjected to gravel impact and temperature changes, or the condition where the chassis sensor 1 is simultaneously subjected to rain, gravel impact, and temperature changes.

[0029] Thus, by setting up the environmental simulation component 3, the durability of the chassis sensor 1 under rain and gravel impact conditions can be tested, or the durability of the chassis sensor 1 under rain and temperature change conditions can be tested, or the durability of the chassis sensor 1 under gravel impact and temperature change conditions can be tested, or the durability of the chassis sensor 1 under rain, gravel impact and temperature change conditions can be tested, thereby enabling the chassis sensor test equipment 100 to test the durability of the chassis sensor 1 under various complex working conditions.

[0030] According to the chassis sensor test equipment 100 of the present invention, the chassis sensor 1 can be supported and fixed by setting the test bench 2 to prevent the chassis sensor 1 from falling and being damaged during the test. By including at least two of the liquid spray structure 31, solid spray structure 32 and temperature control structure 33 in the environmental simulation component 3, the environmental simulation component 3 can simulate a variety of complex working conditions. Thus, the chassis sensor test equipment 100 can test the durability of the chassis sensor 1 under a variety of complex working conditions, perform comprehensive verification of the chassis sensor 1, shorten the test time and improve the test efficiency.

[0031] In some embodiments, the test equipment 100 for chassis sensors further includes a test chamber 4, with the test bench 2 located inside the test chamber 4, and the liquid spraying structure 31, the solid spraying structure 32, and the temperature control structure 33 all located outside the test chamber 4.

[0032] Specifically, the test chamber 4 can be constructed as a box, forming an internal test space with a certain volume. The test platform 2 can be placed in the test space, and the chassis sensor 1 fixed on the test platform 2 can also be placed in the test space. This allows the test chamber 4 to isolate the chassis sensor 1 from the external environment, preventing the chassis sensor 1 from being affected by the external environment during the test, and thus avoiding the reduction in the accuracy of the test results due to the influence of the external environment.

[0033] Meanwhile, the liquid spraying structure 31, the solid spraying structure 32, and the temperature control structure 33 are all located outside the test chamber 4, such as... Figure 1 As shown, the environmental simulation component 3 includes a liquid spray structure 31, a solid spray structure 32, and a temperature control structure 33. These components can be selectively activated, allowing the environmental simulation component 3 to simulate various complex operating conditions. This enables the chassis sensor test equipment 100 to test the durability of the chassis sensor 1 under these conditions. By placing the liquid spray structure 31, solid spray structure 32, and temperature control structure 33 outside the test chamber 4, they are separated from the test bench 2. This avoids the liquid spray structure 31, solid spray structure 32, and temperature control structure 33 occupying internal space within the test chamber 4 and prevents interference between them and the chassis sensor 1, thus avoiding any impact on the chassis sensor 1 itself or the test results.

[0034] It should be noted that the top wall or one of the side walls of the test chamber 4 can be constructed to be openable relative to the test chamber 4, so as to facilitate the removal and placement of the chassis sensor 1.

[0035] In some embodiments, the test chamber 4 is provided with a first chamber opening 41, a second chamber opening 42, and a third chamber opening 43 spaced apart; wherein, the liquid spraying structure 31 is connected to the first chamber opening 41 and is adapted to spray liquid from the first chamber opening 41 toward the test chamber 4, the solid spraying structure 32 is connected to the second chamber opening 42 and is adapted to spray solid particles from the second chamber opening 42 toward the test chamber 4, and the temperature control structure 33 is connected to the third chamber opening 43 and is adapted to deliver temperature-controlled airflow from the third chamber opening 43 toward the test chamber 4.

[0036] Specifically, such as Figures 1-2 As shown, the environmental simulation component 3 includes a liquid spray structure 31, a solid spray structure 32, and a temperature control structure 33. The liquid spray structure 31, the solid spray structure 32, and the temperature control structure 33 are all located outside the test chamber 4. The test chamber 4 is provided with a first chamber opening 41, a second chamber opening 42, and a third chamber opening 43. The first chamber opening 41, the second chamber opening 42, and the third chamber opening 43 can all connect the internal space of the test chamber 4 with the outside.

[0037] The liquid spraying structure 31 is connected to the first box opening 41 and is adapted to spray liquid from the first box opening 41 toward the test chamber 4. The liquid spraying structure 31 can be correspondingly set with the first box opening 41, and the liquid spraying structure 31 can be connected to the first box opening 41 so that the liquid spraying structure 31 can spray liquid from the first box opening 41 toward the chassis sensor 1 to simulate the working condition of rain impact. The solid spraying structure 32 is connected to the second box opening 42 and is adapted to spray solid particles from the second box opening 42 toward the test chamber 4. The solid spraying structure 32 can be correspondingly set with the second box opening 42, and the solid spraying structure 32 can be connected to the second box opening 42 so that the solid spraying structure 32 can spray solid particles from the second box opening 42 toward the chassis sensor 1 to simulate the working condition of sand and gravel impact.

[0038] The temperature control structure 33 is connected to the third chamber opening 43 and is adapted to deliver temperature-controlled airflow from the third chamber opening 43 into the test chamber 4. This allows the temperature control structure 33 to be correspondingly positioned with the third chamber opening 43, enabling it to deliver high-temperature or low-temperature airflow from the third chamber opening 43 towards the chassis sensor 1 to simulate temperature changes. Furthermore, the first chamber opening 41, the second chamber opening 42, and the third chamber opening 43 are positioned on the test chamber 4. The separation arrangement allows for a certain distance between the first chamber opening 41, the second chamber opening 42, and the third chamber opening 43. This enables the liquid spray structure 31, the solid spray structure 32, and the temperature control structure 33 to be connected to different positions on the test chamber 4, thereby improving the reliability of the connection between the liquid spray structure 31, the solid spray structure 32, and the temperature control structure 33 and the test chamber 4. It also avoids interference between the liquid spray structure 31, the solid spray structure 32, and the temperature control structure 33, which could reduce the accuracy of the test results.

[0039] In some embodiments, the first chamber opening 41 and the second chamber opening 42 are spaced apart on the top wall of the test chamber 4; and / or, the third chamber opening 43 is provided on the side wall of the test chamber 4.

[0040] Specifically, the first chamber opening 41, the second chamber opening 42, and the third chamber opening 43 are spaced apart on the test chamber 4, wherein, as shown... Figure 2As shown, the first chamber opening 41 and the second chamber opening 42 can be spaced apart on the top wall of the test chamber 4, so that both the liquid spraying structure 31 and the solid spraying structure 32 can be connected to the top of the test chamber 4. This allows both the liquid spraying structure 31 and the solid spraying structure 32 to spray liquid or solid particles from the top of the chassis sensor 1 toward the chassis sensor 1. The first chamber opening 41 and the second chamber opening 42 are spaced apart, so that the first chamber opening 41 and the second chamber opening 42 can be distributed at a distance from each other on the top wall of the test chamber 4. This allows the liquid spraying structure 31 and the solid spraying structure 32 to be connected to different positions on the top wall of the test chamber 4, thereby avoiding interference between the liquid spraying structure 31 and the solid spraying structure 32, improving the connection reliability between the liquid spraying structure 31 and the solid spraying structure 32 and the test chamber 4, and improving the working reliability of the liquid spraying structure 31 and the solid spraying structure 32 individually.

[0041] At the same time, such as Figure 2 As shown, the third chamber opening 43 can be set on the side wall of the test chamber 4, so that the temperature control structure 33 can be connected to one side of the test chamber 4. This allows the temperature control structure 33 to deliver high-temperature or low-temperature airflow from the side of the chassis sensor 1 to the chassis sensor 1. The third chamber opening 43 can be spaced apart from the first chamber opening 41 and the second chamber opening 42. This allows the liquid spray structure 31, the solid spray structure 32, and the temperature control structure 33 to be connected to different positions in the test chamber 4, thereby avoiding interference between them and improving the connection reliability of each of them to the test chamber 4. This also improves the operational reliability of each of them.

[0042] In some embodiments, the test chamber 4 is connected to a recovery component 5, which is used to recover liquid and solid particles inside the test chamber 4; and / or, the bottom wall of the test chamber 4 is constructed as an inclined bottom wall, and the inclined bottom wall is provided with a recovery port; and / or, the bottom wall of the test chamber 4 is connected to a first driving mechanism, which is used to drive the bottom wall of the test chamber 4 to tilt.

[0043] Specifically, such as Figure 1 As shown, the recycling component 5 is used to recycle liquid and solid particles inside the test chamber 4. By connecting the recycling component 5 to the test chamber 4, the internal space of the recycling component 5 and the test chamber 4 can be connected. This allows the recycling component 5 to recycle the liquid sprayed into the test chamber 4 by the liquid spraying structure 31 and the solid spraying structure 32 sprayed into the test chamber 4. This enables the recycling and reuse of liquid and solid particles inside the test chamber 4, reducing resource waste.

[0044] Furthermore, the bottom wall of the test chamber 4 can be constructed as an inclined bottom wall, which is inclined at a certain angle relative to the horizontal plane. This allows the liquid and solid particles inside the test chamber 4 to flow from a higher position to a lower position along the inclined bottom wall under their own gravity. The recovery component 5 can then be connected to the lower position on the inclined bottom wall to facilitate the recovery of the liquid and solid particles inside the test chamber 4. A recovery port is provided on the inclined bottom wall to connect the internal space of the test chamber 4 to the outside. The recovery component 5 can then be connected to the recovery port, allowing the liquid and solid particles inside the test chamber 4 to enter the recovery component 5 through the recovery port, thereby realizing the recovery of the liquid and solid particles.

[0045] The recovery port can be positioned at a lower location on the inclined bottom wall, so that the liquid and solid particles in the test chamber 4 can flow towards the recovery port while flowing along the inclined bottom wall, so that they can enter the recovery component 5 through the recovery port.

[0046] Furthermore, the bottom wall of the test chamber 4 can be configured as a movable bottom wall. For example, the bottom wall of the test chamber 4 can be hinged to the test chamber 4, allowing the bottom wall of the test chamber 4 to rotate relative to the test chamber 4. This allows the bottom wall of the test chamber 4 to move from a horizontal direction to an angle relative to the horizontal plane. A first drive mechanism can be connected to the bottom wall of the test chamber 4 to provide driving force to drive the bottom wall of the test chamber 4 to rotate. After the chassis sensor 1 completes the test, the first drive mechanism drives the bottom wall of the test chamber 4 to rotate a certain angle relative to the horizontal plane, allowing the liquid and solid particles inside the test chamber 4 to flow along the bottom wall of the test chamber 4 towards the recovery port, facilitating their recovery by the recovery assembly 5. The first drive mechanism can be a drive motor.

[0047] In some embodiments, the test chamber 4 is provided with a control panel 6 on the outside, the control panel 6 being used to control the opening or closing of the environmental simulation component 3; and / or, the test chamber 4 is provided with a viewing window 7.

[0048] Specifically, the test chamber 4 is equipped with a control panel 6, which is used to control the opening and closing of the environmental simulation component 3. The control panel 6 can be connected to the environmental simulation component 3, and buttons or keys can be set on the control panel 6 so that users can control the environmental simulation component 3 by pressing the buttons or keys, thereby realizing the automatic opening or closing of the environmental simulation component 3, which can improve the convenience of operation. Moreover, the environmental simulation component 3 includes a liquid spray structure 31, a solid spray structure 32, and a temperature control structure 33. That is, users can control the opening and closing of the liquid spray structure 31, the solid spray structure 32, and the temperature control structure 33 through the control panel 6, thereby realizing different combinations of various working conditions. This allows the environmental simulation component 3 to simulate various complex working conditions, so that the chassis sensor test equipment 100 can test the durability of the chassis sensor 1 under various complex working conditions, perform comprehensive verification of the chassis sensor 1, shorten the test time, and improve the test efficiency.

[0049] The control panel 6 is located on the outside of the test chamber 4, so that the control panel 6 is oriented towards the user, so that the user can control the environmental simulation component 3 through the control panel 6.

[0050] Meanwhile, a viewing window 7 can be set on the test chamber 4. The viewing window 7 can be a transparent plastic plate, etc., so that the user can observe the status of the chassis sensor 1 inside the test chamber 4 from the outside of the test chamber 4 through the viewing window 7. The status of the chassis sensor 1 can be monitored in real time, and the durability of the chassis sensor 1 can be judged based on the appearance and shape changes of the chassis sensor 1. This also avoids the impact of frequently opening the test chamber 4 on the test results.

[0051] In some embodiments, the test bench 2 is configured as a vibration table, and the vibration table is connected to a second driving mechanism, which is used to drive the vibration table to vibrate.

[0052] Specifically, the test bench 2 is used to support the chassis sensor 1. The test bench 2 is constructed as a vibration table, which can vibrate. The chassis sensor 1 is placed on the vibration table, so that the vibration table can drive the chassis sensor 1 to vibrate together. This can simulate the vibration conditions of the chassis sensor 1 during vehicle operation, test the fatigue life of the chassis sensor 1, and conduct a more comprehensive verification of the chassis sensor 1 to improve the accuracy of the test results. At the same time, the vibration table is connected to a second drive mechanism, which is used to provide driving force to the vibration table to drive the chassis sensor 1 to vibrate. The second drive mechanism can be a drive motor.

[0053] The second drive mechanism can be located on the outside of the test chamber 4 to avoid interference between the second drive mechanism and the chassis sensor 1, and to avoid damage to the second drive mechanism by liquid and solid particles. Moreover, the vibration intensity and vibration frequency of the vibration table can be controlled through the second drive mechanism, thereby further improving the accuracy of the test results.

[0054] In some embodiments, the liquid spraying structure 31 includes a spray pipe 311 and a first solenoid valve. One end of the spray pipe 311 has a liquid spray nozzle and the other end is connected to an external water source. The first solenoid valve is used to control the on / off state of the spray pipe 311. And / or, the solid spraying structure 32 includes a shot blasting pipe 321 and a sand and gravel feeding port 322. One end of the shot blasting pipe 321 is connected to the sand and gravel feeding port 322 through a sand feeding pipe 323 and the other end has a solid spraying port. And / or, the temperature control structure 33 includes an air supply pipe 331 and a temperature generator 332. One end of the air supply pipe 331 has an air supply port and the other end is connected to an external air source. The temperature generator 332 is connected between the external air source and the test chamber 4.

[0055] Specifically, the liquid spray structure 31 is used to spray liquid toward the chassis sensor 1. The liquid can be water or the like. The liquid spray structure 31 includes a spray pipe 311 and a first solenoid valve. One end of the spray pipe 311 has a spray nozzle, and the other end is connected to an external water source. The external water source is used to provide water. The spray nozzle is used to spray water toward the chassis sensor 1. The spray pipe 311 is used to guide the water. The spray nozzle can be connected to the first housing opening 41, so that the spray pipe 311 can connect the external water source with the internal space of the test chamber 4, thereby allowing water to flow from the external water source along the spray pipe 311. The water flows to the spray nozzle and sprays towards the chassis sensor 1 to simulate the working condition of the chassis sensor 1 being impacted by rainwater. The first solenoid valve is used to control the opening and closing of the spray pipe 311. The first solenoid valve can be set in the spray pipe 311 so that the first solenoid valve can connect or disconnect the external water source from the internal space of the test chamber 4, thereby selectively spraying water towards the chassis sensor 1 to simulate the working conditions with and without rainwater impact. This allows for testing the durability of the chassis sensor 1 under different working conditions and increases the applicability of the chassis sensor test equipment 100.

[0056] Furthermore, the solid blasting structure 32 is used to blast solid particles toward the chassis sensor 1. The solid particles can be sand or gravel. The solid blasting structure 32 includes a shot blasting pipe 321 and a sand and gravel feeding port 322. One end of the shot blasting pipe 321 is connected to the sand and gravel feeding port 322 through a sand feeding pipe 323, and the other end forms a solid blasting port. The sand and gravel feeding port 322 can provide sand and gravel through user input. The solid blasting port is used to blast sand and gravel toward the chassis sensor 1. The shot blasting pipe 321 and the sand feeding pipe 323 are used to guide the sand and gravel. The solid blasting port can be connected to the second chamber opening 42, so that the sand feeding pipe 323 and the shot blasting pipe 321 can connect the sand and gravel feeding port 322 with the internal space of the test chamber 4. This allows the sand and gravel to flow from the sand and gravel feeding port 322 along the sand feeding pipe 323 and the shot blasting pipe 321 to the solid blasting port, and then be blasted toward the chassis sensor 1 from the solid blasting port to simulate the working condition of the chassis sensor 1 being impacted by sand and gravel.

[0057] Furthermore, the temperature control structure 33 is used to supply temperature-controlled airflow to the chassis sensor 1. The temperature-controlled airflow can be high-temperature airflow or low-temperature airflow. The temperature control structure 33 includes an air supply duct 331 and a temperature generator 332. One end of the air supply duct 331 forms an air outlet, and the other end is connected to an external air source. The external air source is used to provide airflow, and the air outlet is used to supply airflow toward the chassis sensor 1. The air supply duct 331 is used to guide the airflow. The air outlet can be connected to the third chamber opening 43, so that the air supply duct 331 can connect the external air source with the internal space of the test chamber 4, thereby enabling... Airflow can flow from an external water source along the air supply duct 331 to the air outlet, and then be delivered from the air outlet toward the chassis sensor 1. The temperature generator 332 may include a heater and a cooler, both of which can be selectively operated. The temperature generator 332 is connected between the external air source and the test chamber 4, so that when the airflow flows from the external air source to the test chamber 4, it can pass through the temperature generator 332 and be heated by the heater or cooled by the cooler. This allows the airflow flowing into the test chamber 4 to be either a high-temperature airflow or a low-temperature airflow to simulate temperature change conditions.

[0058] It should be noted that, in practice, a fan, a motor, and a temperature sensor can also be installed in the temperature control structure 33. The motor and the fan are electrically connected so that the motor can drive the fan to run. The fan is placed on the side of the air supply duct 331 away from the test chamber 4 so that the fan can accelerate the airflow and thus allow the interior of the test chamber 4 to quickly reach the required temperature. In addition, the temperature sensor can be placed between the test chamber 4 and the temperature generator 332, or the temperature sensor can be placed inside the test chamber 4 to control the temperature required for the test.

[0059] In some embodiments, the solid blasting structure 32 further includes a gas storage tank 324 and a second solenoid valve 3251. The gas storage tank 324 is used to store compressed gas and is connected to one end of the shot blasting pipe 321 through a connecting pipe 325. The second solenoid valve 3251 is disposed on the connecting pipe 325 and is used to control the opening and closing of the connecting pipe 325.

[0060] In other words, the connecting pipe 325 is used to guide the gas. Connecting the connecting pipe 325 to the gas storage tank 324 and the shot peening pipe 321 allows the compressed gas in the gas storage tank 324 to flow along the connecting pipe 325 to the shot peening pipe 321, providing power to the sand and gravel to achieve the blasting of sand and gravel. The second solenoid valve 3251 is used to control the opening and closing of the connecting pipe 325. The second solenoid valve 3251 is set in the connecting pipe 325 so that the second solenoid valve 3251 can connect or disconnect the gas storage tank 324 and the shot peening pipe 321, thereby selectively providing power to the sand and gravel to simulate working conditions with and without sand and gravel impact. This allows for testing the durability of the chassis sensor 1 under different working conditions, increasing the applicability of the chassis sensor testing equipment 100.

[0061] In some embodiments, a pressure regulator 3252 is connected between the gas storage tank 324 and one end of the shot peening pipe 321. The pressure regulator 3252 is used to regulate the pressure of the gas entering the shot peening pipe 321.

[0062] Specifically, the pressure reducer 3252 is used to control the pressure of gas or liquid. By connecting the pressure reducer 3252 between the gas storage tank 324 and the shot peening pipe 321, the pressure reducer 3252 can be used to adjust the pressure of the gas entering the shot peening pipe 321. This allows control over the pressure of the compressed gas flowing from the gas storage tank 324 to the shot peening pipe 321, thereby enabling adjustment of the intensity of sand and gravel blasting. It can also test the durability of the chassis sensor 1 under different working conditions, increasing the applicability of the chassis sensor testing equipment 100.

[0063] In such Figure 3 In the embodiment shown, the solid blasting structure 32 also includes a pressure gauge 3253, a vibrating conveyor 3221, and a protective cover 3222. The pressure gauge 3253 is located between the pressure reducer 3252 and the shot blasting pipe 321 and is used to test the working pressure to facilitate the control of the blasting intensity of sand and gravel. The vibrating conveyor 3221 is connected to the sand and gravel feeding port 322 and can drive the sand and gravel at the sand and gravel feeding port 322 to vibrate to ensure reliable flow of sand and gravel. The protective cover 3222 is located on the outside of the shot blasting pipe 321 and overlaps with the test chamber 4 to prevent sand and gravel from splashing.

[0064] It should also be noted that the chassis sensor test equipment 100 of the present invention can be used not only to test the durability of the chassis sensor 1, but also to test other structural components or sensors.
