Description

Technical Field

[0001] This utility model relates to the technical field of automobile inspection devices, specifically an automobile sideslip inspection device. Background Technology

[0002] Vehicle sideslip refers to the phenomenon where a vehicle, due to braking, rotational inertia, or other factors, experiences lateral movement (i.e., sideways slippage) of one or both wheels on one axle. When encountering slippery, oily, or icy road surfaces, the coefficient of friction decreases and becomes asymmetrical, reducing the wheel load and road adhesion. Even a slight lateral force can trigger sideslip. Therefore, vehicle sideslip testing needs to be conducted under various road conditions to ensure the comprehensiveness and objectivity of the test results.

[0003] The utility model with announcement number CN214309517U discloses a car sideslip testing platform, which includes a frame with two testing plates along its length. The upper surface of the testing plates has a useful placement groove, and a sliding plate is embedded in the placement groove. The sliding plate is fixed in the placement groove by a limiting member. By changing the sliding plate with different friction, the testing plates can simulate and test the sideslip data of the car on the ground with different friction, so as to improve the accuracy and comprehensiveness of the sideslip data of the car inspection.

[0004] In the above structure, when installing the test plate, downward pressure needs to be applied to make the slide plate overcome the thrust of the return spring and install it into the placement groove. Then, continuous downward pressure needs to be maintained to prevent the slide plate from being bounced up until the pressure plate is pressed onto the slide plate and locked in place to complete the installation. The operation is relatively cumbersome, and the snap-fit ​​connection at the end of the pressure plate is prone to loosening under dynamic load. In addition, when the slide plate is disassembled, the slide plate will bounce up suddenly under the action of the return spring the moment the pressure plate is released, which may cause personal injury or damage to the disassembly structure. Therefore, in order to solve the above problems, a vehicle sideslip test device is proposed. Utility Model Content

[0005] The technical problem this utility model aims to solve is to provide a vehicle sideslip testing device. This vehicle testing device has a clamping and fixing structure and a spring-loaded mechanism installed on the testing table. The clamping and fixing structure includes opposing clamps and side clamps, which, through their combined action, can firmly fix the testing slide plate in the placement slot. The interlocking action between the L-shaped clamp and the slot can prevent the testing slide plate from moving upward, ensuring the reliability of the clamping and fixing and being able to withstand frequent dynamic loads. In addition, the spring-loaded mechanism is used to lift the testing slide plate during disassembly. Because it can control the degree of lift, it will not pop out on its own, which facilitates efficient and safe installation and disassembly. This solves the technical problems in the comparative technology where the connection of the testing plate clamping and fixing is prone to loosening under the dynamic load of sideslip testing, causing the testing plate to lose its restraint and shake, and the lack of control measures for the return spring, which will always apply external pushing force, thus bringing many inconveniences to the installation and disassembly work.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A vehicle sideslip testing device includes a testing platform with symmetrically arranged placement slots. A testing slide plate is installed in the slots, and a locking groove is formed at the edge of the testing slide plate. Opposing clamps and side clamps are used to clamp and fix the testing slide plate. A pop-up mechanism is used to pop the testing slide plate out of the placement slots during disassembly. The opposing clamps and side clamps are identical in structure, each including an L-shaped clamp plate with an adjusting screw threaded to the testing platform. The size of the L-shaped clamp plate matches the size of the locking groove. In this structure, the opposing clamps and side clamps can firmly fix the testing slide plate in the placement slot through their combined action. The locking action between the L-shaped clamp plate and the locking groove can prevent the testing slide plate from moving upward, ensuring the reliability of the clamping and fixing, and can withstand frequent dynamic loads. In addition, the pop-up mechanism is used to pop the testing slide plate out during disassembly. Since it can control the degree of pop-up, it will not pop out on its own, which facilitates efficient and safe installation and disassembly.

[0008] In one possible implementation, the pop-up mechanism includes a tray disposed in a placement slot and a fixing lug fixedly disposed on the side of the testing table. A guide rod is fixedly disposed on the fixing lug, and the tray is slidably sleeved on the guide rod on both sides. Based on the above structure, the tray can move up and down along the guide rod. That is, when it moves up, it lifts up the testing slide plate, making it easy for the staff to remove the testing slide plate. When it moves down, it frees up the placement space of the placement slot, so that the testing slide plate can be installed in it.

[0009] In one possible implementation, the guide rod is fitted with a spring, with its upper and lower ends contacting the support plate and the fixing lug, respectively. A loosening wheel is threadedly connected to the top of the guide rod. Under the thrust of the spring, the support plate always maintains an upward trend, while its upward position is constrained by the loosening wheel. Based on the above technical solution, when the loosening wheel moves upward, the support plate will follow the spring's thrust and move upward. When the loosening wheel moves downward, it will squeeze the support plate to overcome the spring's thrust and move downward, thus achieving control over the position of the support plate.

[0010] In one possible implementation, the back of the L-shaped clamp is fixedly provided with symmetrically arranged sliding rods, which slide in contact with the testing table. An adjusting wheel is fixedly connected to the end of the adjusting screw. The sliding rods ensure that the L-shaped clamp does not deflect during the sliding process.

[0011] In one possible implementation, the testing platform has a receiving groove that communicates with the placement groove. The size of the receiving groove matches the size of the L-shaped clamp. At the same time, the opening of the receiving groove is machined with a chamfer. The opening of the receiving groove allows the L-shaped clamp to be fully embedded in it without interfering with the placement space of the placement groove, and facilitates the removal and placement of the testing slide.

[0012] In one possible implementation, the tray includes a strip plate with expansion plates fixedly disposed on both sides, and connecting plates that slide in contact with the guide rod are fixedly connected to both ends of the strip plate. The upper surface of the expansion plate is flush with the upper surface of the strip plate. The expansion plate can increase the contact area between the strip plate and the detection slide plate, and avoid leaving squeezing marks on the lower surface of the detection slide plate due to the small contact area.

[0013] In one possible implementation, the bottom of the placement slot is provided with a storage slot, the cross-section of which is an inverted convex shape, and its size is consistent with the size of the part of the strip plate with the expansion plate. The opening of the storage slot provides the necessary structure for the complete storage of the tray, and can avoid the outward protrusion of the tray from interfering with the placement of the detection slide plate.

[0014] In one possible implementation, the detection platform is provided with a guide groove corresponding to the position of the pop-up mechanism. The connecting plate is slidably disposed in the guide groove, and the width of the connecting plate is the same as the width of the guide groove. The guide groove can constrain and guide the connecting plate, that is, constrain and guide the movement of both ends of the pallet, ensuring that the pallet can move straight up and down.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] The vehicle inspection device is equipped with a clamping and fixing structure and a spring-loaded mechanism on the inspection table. The clamping and fixing structure includes opposing clamps and side clamps, which can firmly fix the inspection slide in the placement slot through their combined action. The interlocking action between the L-shaped clamp and the slot can prevent the inspection slide from moving upward, ensuring the reliability of the clamping and fixing and being able to withstand frequent dynamic loads.

[0017] In addition, the pop-up mechanism is used to pop up the detection slide during disassembly. Because it can control the degree of pop-up, it will not pop out on its own, which makes the installation and disassembly work efficient and safe. Attached Figure Description

[0024] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0025] like Figure 1 - Figure 2As shown, this embodiment provides a vehicle sideslip testing device, including a testing platform 1 with symmetrically arranged placement slots 11. A testing slide plate 2 is installed in the slots, and a locking groove 21 is provided at the edge of the testing slide plate 2. Opposing clamps 31 and side clamps 32 are used to clamp and fix the testing slide plate 2. A pop-up mechanism 4 is used to pop the testing slide plate 2 out of the placement slots 11 during disassembly. The opposing clamps 31 and side clamps 32 are identical, each including an L-shaped clamping plate 301, on which an adjusting screw 302 threadedly connected to the testing platform 1 is rotatably connected. The dimensions of 301 match those of the slot 21. In the above structure, the opposing clamp 31 and the side clamp 32 work together to firmly fix the detection slide plate 2 in the placement slot 11. The interlocking action between the L-shaped clamp 301 and the slot 21 prevents the detection slide plate 2 from moving upward, ensuring the reliability of the clamping and fixing, and enabling it to withstand frequent dynamic loads. In addition, the pop-up mechanism 4 is used to pop up the detection slide plate 2 during disassembly. Since it can control the degree of pop-up, it will not pop up on its own, which facilitates efficient and safe installation and disassembly.

[0026] The pop-up mechanism 4 includes a support plate 41 disposed in the placement slot 11 and a fixing ear 42 fixedly disposed on the side of the testing table 1. A guide rod 43 is fixedly disposed on the fixing ear 42. The support plate 41 is slidably sleeved on the guide rod 43 on both sides. Based on the above structure, the support plate 41 can move up and down along the guide rod 43. That is, when it moves up, it lifts the testing slide plate 2, making it easy for the staff to remove the testing slide plate 2. When it moves down, it frees up the placement space in the placement slot 11, so that the testing slide plate 2 can be installed in it. In addition, the guide rod 43 The outer sleeve is equipped with a spring 44, the upper and lower ends of which contact the support plate 41 and the fixing lug 42 respectively. The top of the guide rod 43 is threadedly connected to a loosening wheel 45. Under the pushing force of the spring 44, the support plate 41 always maintains an upward trend, while its upward position is constrained by the loosening wheel 45. Based on the above technical solution, when the loosening wheel 45 moves upward, the support plate 41 will follow the spring 44 and move upward. When the loosening wheel 45 moves downward, it will squeeze the support plate 41 to overcome the pushing force of the spring 44 and move downward, thus realizing the control of the position of the support plate 41.

[0027] like Figure 3As shown, the back of the L-shaped clamp 301 is fixedly provided with symmetrically arranged sliding rods 304, which slide in contact with the testing table 1. The end of the adjusting screw 302 is fixedly connected with an adjusting wheel 303. The setting of the sliding rods 304 can ensure that the L-shaped clamp 301 does not deflect during the sliding process. In addition, the testing table 1 is provided with a receiving groove 14 that communicates with the placement groove 11. Its size matches the size of the L-shaped clamp 301. At the same time, the opening of the receiving groove 14 is machined with a chamfer 15. The opening of the receiving groove 14 allows the L-shaped clamp 301 to be completely embedded in it without interfering with the placement space of the placement groove 11, which facilitates the removal and placement of the testing slide plate 2.

[0028] like Figure 4 As shown, the tray 41 includes a strip plate 411 with expansion plates 412 fixedly arranged on both sides. At the same time, the two ends of the strip plate 411 are fixedly connected to connecting plates 413 that slide in contact with the guide rod 43. The upper surface of the expansion plate 412 is flush with the upper surface of the strip plate 411. The expansion plate 412 can increase the contact area between the strip plate 411 and the detection slide plate 2, and avoid leaving squeezing marks on the lower surface of the detection slide plate 2 due to the small contact area.

[0029] like Figure 3 As shown, the bottom of the placement groove 11 is provided with a storage groove 12, the cross-section of which is an inverted convex shape, and its size is consistent with the size of the part of the strip plate 411 with the expansion plate 412. The opening of the storage groove 12 provides the necessary structure for the complete storage of the tray 41, and can avoid the outward protrusion of the tray 41 from interfering with the placement of the detection slide plate 2. In addition, the detection table 1 is provided with a guide groove 13 corresponding to the setting position of the pop-up mechanism 4. The connecting plate 413 is slidably set in the guide groove 13, and the width of the connecting plate 413 is the same as the width of the guide groove 13. The guide groove 13 can constrain and guide the connecting plate 413, that is, constrain and guide the movement of both ends of the tray 41, ensuring that the tray 41 can go straight up and down.

[0030] The working principle and usage process of this utility model:

[0031] The vehicle inspection device is equipped with a clamping and fixing structure and a spring-loaded mechanism 4 on the inspection table 1. The clamping and fixing structure includes opposing clamps 31 and side clamps 32. Through their combined action, the inspection slide plate 2 can be firmly fixed in the placement slot 11. The interlocking action between the L-shaped clamp 301 and the slot 21 can prevent the inspection slide plate 2 from moving upward, ensuring the reliability of the clamping and fixing and being able to withstand frequent dynamic loads.

[0032] Additionally, the pop-up mechanism 4 is used to pop up the detection slide plate 2 during disassembly. Since it can control the degree of pop-up, it will not pop out on its own, which facilitates efficient and safe installation and disassembly. Specifically, under the pushing force of the spring 44, the support plate 41 always maintains an upward trend, and its upward position is constrained by the loosening wheel 45. Based on the above technical solution, when the loosening wheel 45 moves upward, the support plate 41 will follow the spring 44 and move upward. When the loosening wheel 45 moves downward, it will squeeze the support plate 41 to overcome the pushing force of the spring 44 and move downward, thus realizing the control of the position of the support plate 41.

[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
