Description

Technical Field

[0001] This utility model relates to the field of automotive testing technology, specifically to a vibration testing device for automotive road testing. Background Technology

[0002] With societal development, modern automotive design prioritizes lightweight construction, safety, and comfort. When a car travels on uneven or potholed roads, its operating conditions change accordingly, causing different parts of the vehicle to exhibit varying states. To test a car's performance under different road conditions (such as fatigue durability, shock absorption, and noise levels), it is necessary to conduct tests under various operating conditions.

[0003] Existing automotive testing equipment is difficult to test the driving conditions of vehicles on different roads, such as bumpy roads, washboard roads, and pothole roads, resulting in a limited range of applications. Therefore, an automotive road test vibration testing device has been proposed. Utility Model Content

[0004] This invention proposes a vibration testing device for automobile road testing, which solves the problem that automobile testing devices in related technologies are difficult to test the driving conditions of automobiles on different roads, such as bumpy roads, washboard roads and pothole roads, thus resulting in a limited range of applications.

[0005] The technical solution of this utility model is as follows: a vibration testing device for automobile road testing, comprising: a test chamber;

[0006] Multiple through slots of different sizes are formed through the top of the test chamber. Two electric telescopic rods are fixedly installed on the left and right sides of the test chamber. The output ends of the two electric telescopic rods are fixedly connected to the mounting plates. Multiple strip plates are fixedly installed on one side of the mounting plates.

[0007] Multiple electric push rods are fixedly installed on the bottom wall of the test chamber. The output ends of the multiple electric push rods are fixedly connected to a lifting plate. Multiple protrusions are fixedly installed on the top of the lifting plate. The multiple protrusions are all different in size.

[0008] Preferably, two triangular blocks are fixedly installed on the front and rear sides of the test box, and multiple anti-slip strips are fixedly installed on the top of the two triangular blocks.

[0009] Preferably, two sliding grooves are formed on the left and right sides of the test chamber, and a slider is slidably connected inside the two sliding grooves.

[0010] Preferably, a hydraulic rod is fixedly installed on the inner top wall of the two slides, the output end of the hydraulic rod is connected to the slider, and a wheel is rotatably connected to one side of the slider.

[0011] Preferably, two L-shaped rods are fixedly installed on one side of one of the two triangular blocks, and anti-slip sleeves are fitted on the top of the outer side walls of the two L-shaped rods.

[0012] The working principle and beneficial effects of this utility model are as follows:

[0013] 1. When in use, by driving the car onto the test chamber, the performance of the car's suspension system can be tested by using the different sized slots as the car passes through multiple slots, ensuring that it can provide good shock absorption under complex road conditions. At the same time, the noise and vibration levels generated by the vehicle when driving on bumpy roads can be measured to evaluate the quietness of the car interior.

[0014] 2. When testing a car on a bumpy road, the electric push rod is activated, which pushes the lifting plate upward, causing the protrusion to extend through the slot. Then, when the car passes over the protrusion, different sized protrusions are used to test whether the car body and chassis structure can withstand repeated impacts without deformation or damage, ensuring that the car has sufficient rigidity and durability, extending its service life, and ensuring driving safety.

[0015] 3. When testing a car on a washboard road, the electric telescopic rod is activated and retracted, moving multiple strips on the mounting plate to the top of the test chamber. As the car tires pass over these strips, the tires and rims are tested under extreme conditions to identify and resolve potential problems, preventing safety hazards caused by component failure. This achieves the purpose of testing under different road driving conditions and effectively improves the applicability. Attached Figure Description

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figure 1 - Figure 4 A vibration testing device for automobile road testing, comprising: a test chamber 1;

[0024] Multiple through slots 2 are opened through the top of the test chamber 1. The multiple through slots 2 are of different sizes. Two electric telescopic rods 3 are fixedly installed on the left and right sides of the test chamber 1. The output ends of the two electric telescopic rods 3 are fixedly connected to the mounting plate 4. Multiple strip plates 5 are fixedly installed on one side of the mounting plate 4.

[0025] Multiple electric push rods 6 are fixedly installed on the bottom wall inside the test chamber 1. The output ends of the multiple electric push rods 6 are fixedly connected to a lifting plate 7. Multiple protrusions 8 are fixedly installed on the top of the lifting plate 7. The sizes of the multiple protrusions 8 are all different.

[0026] The technical solution provided by this utility model is as follows: When in use, a car is driven onto the test chamber 1. As the car passes through multiple through-slots 2 of different sizes, the performance of the car's suspension system can be tested to ensure it provides good shock absorption under complex road conditions. Simultaneously, the noise and vibration levels generated when the vehicle is driving on bumpy roads are measured to assess the quietness of the vehicle interior. When testing the car on a bumpy road, an electric push rod 6 is activated, which pushes the lifting plate 7 upward, causing the protrusions 8 to extend through the through-slots 2. Then, as the car passes over the protrusions 8, the different sizes of the protrusions 8 are used to detect the structure of the car body and chassis. The test aims to determine whether the structure can withstand repeated impacts without deformation or damage, ensuring sufficient rigidity and durability of the vehicle, extending its service life, and guaranteeing driving safety. When testing a car on a washboard road, the electric telescopic rod 3 is activated and retracted, causing multiple strip plates 5 on the mounting plate 4 to move to the top of the test chamber 1. When the car tires pass over the multiple strip plates 5, the test examines the working condition of the car tires and rims under extreme conditions, identifies and resolves potential problems, and avoids safety hazards caused by component failure. This achieves the purpose of testing the vehicle's performance under different road driving conditions and effectively improves its applicability.

[0027] Furthermore, two triangular blocks 9 are fixedly installed on the front and rear sides of the test chamber 1, and multiple anti-slip strips 10 are fixedly installed on the top of the two triangular blocks 9.

[0028] Specifically, the triangular block 9 facilitates the car's movement to the top of the test chamber 1, and the multiple anti-slip strips 10 on the triangular block 9 increase the friction between the car tires and the triangular block 9 to prevent slippage.

[0029] Furthermore, two sliding grooves 11 are opened opposite each other on the left and right sides of the test chamber 1. A slider 12 is slidably connected inside the two sliding grooves 11. A hydraulic rod 13 is fixedly installed on the inner top wall of the two sliding grooves 11. The output end of the hydraulic rod 13 is connected to the slider 12. A wheel 14 is rotatably connected to one side of the slider 12. Two L-shaped rods 15 are fixedly installed on one side of one of the two triangular blocks 9. An anti-slip sleeve 16 is fitted on the top of the outer wall of the two L-shaped rods 15.

[0030] Specifically, by activating the hydraulic rod 13, the hydraulic rod 13 pushes the slider 12 to slide downward inside the slide groove 11, so that the wheel 14 contacts the ground. At the same time, the test box 1 is raised. At this time, the L-shaped rod 15 can be held to push the test box 1, so that the wheel 14 rotates, which is used to move the test box 1, effectively improving the flexibility of the test box 1.

[0031] The working principle of this utility model is as follows: When in use, a car is driven onto the test chamber 1. As the car passes through multiple through-slots 2 of different sizes, the performance of the car's suspension system can be tested to ensure it provides good shock absorption under complex road conditions. Simultaneously, the noise and vibration levels generated when the vehicle is driving on bumpy roads are measured to assess the quietness of the interior. When testing the car on a bumpy road, the electric push rod 6 is activated, which pushes the lifting plate 7 upward, causing the protrusion 8 to extend through the through-slots 2. Then, as the car passes over the protrusion 8, the different sizes of the protrusion 8 are used to test the vehicle body and chassis structure. Whether it can withstand repeated impacts without deformation or damage, ensuring that the car has sufficient rigidity and durability, extending its service life, and ensuring driving safety, when testing the car on a washboard road, the electric telescopic rod 3 is activated and retracted, causing multiple strip plates 5 on the mounting plate 4 to move to the top of the test box 1. When the car tires pass over the multiple strip plates 5, it is used to test the working state of the car tires and rims under extreme conditions, identify and solve potential problems, avoid safety hazards caused by component failure, and thus achieve the purpose of different road driving conditions, effectively improving the scope of application.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
