Description

Technical Field

[0001] The utility model relates to the technical field of inspection tables, in particular to an automotive load braking inspection table. Background Technique

[0002] An automotive load braking inspection table, as an advanced automotive detection device, is an important tool specifically used to test the braking performance of automobiles. An automotive load braking inspection table is a device integrating a drum reaction type braking table and a loading function. It applies a load on the drum to simulate the actual load generated on the braking system during vehicle driving, thereby comprehensively and accurately testing the braking performance of the automobile. This device usually consists of a braking force loading system, a sensor system, a data acquisition system, and an auxiliary system, etc. Each system works together to ensure the accuracy and reliability of the test.

[0003] Traditional load braking tables are usually installed on the ground and guide automobiles to drive in through an inclined plate, and their detection rollers are directly exposed to the external environment. However, this design has obvious drawbacks: dust, sundries, etc. in the external environment easily enter the interior of the inspection table. The detection rollers of the load braking table are exposed outside without effective dust-proof measures, resulting in dust, sand, and other sundries being easily attached to the roller surface, increasing the frictional resistance between the wheel and the roller, thereby affecting the accuracy of braking force measurement, bringing uncertainty to the evaluation of vehicle braking performance, and frequent intrusion of dust and sundries requires regular cleaning and maintenance, increasing the usage cost and downtime of the equipment, reducing work efficiency. Therefore, an automotive load braking inspection table is needed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model aims to solve at least one of the above technical defects.

[0005] For this reason, an object of the utility model is to propose an automotive load braking inspection table to solve the problems mentioned in the background technique and overcome the deficiencies existing in the prior art.

[0006] To achieve the above object, an embodiment of one aspect of the present utility model provides an automotive loading brake test bench, including a concrete road surface. An embedding groove is formed on the top surface of the concrete road surface. A metal frame is fixedly connected inside the embedding groove by bolts. A bottom plate is slidably connected to the inner wall of the metal frame. The bottom plate is fixedly connected to the concrete road surface by bolts. A plurality of hydraulic cylinders are fixedly connected to the top surface of the bottom plate. The output ends of the plurality of hydraulic cylinders are fixedly connected to a lifting plate. An avoidance groove is formed on the top surface of the lifting plate. A brake test structure body is fixedly installed on the top surface of the bottom plate. The brake test structure body is slidably connected to the lifting plate through the avoidance groove. A frame is fixedly connected to the bottom surface of the lifting plate. A motor is fixedly connected to the outside of the frame. The output end of the motor is fixedly connected to a lead screw. A driving plate is threadedly connected to the outer surface of the lead screw. The driving plate is slidably connected to the frame. A storage groove is formed on the inner wall of the avoidance groove. A plugging plate is slidably connected inside the storage groove. The plugging plate is slidably connected to the lifting plate through the avoidance groove. A connecting plate is fixedly connected to the bottom surface of the plugging plate. The bottom surface of the connecting plate is fixedly connected to the driving plate.

[0007] Preferably, from any of the above solutions, the lifting plate is parallel to the bottom plate, and the lifting plate is slidably connected to the metal frame.

[0008] Preferably, from any of the above solutions, a guiding plate is connected to the bottom surface of the lifting plate. A guiding rod is fixedly connected to the side surface of the brake test structure body in an embedded manner. The guiding plate is slidably connected to the guiding rod.

[0009] Preferably, from any of the above solutions, a limiting column is fixedly connected to the inner wall of the frame. The driving plate is slidably connected to the limiting column.

[0010] Preferably, from any of the above solutions, a connecting groove is formed on the bottom surface of the lifting plate. The connecting groove is communicated with the storage groove. The connecting plate is slidably connected to the lifting plate through the connecting groove.

[0011] Preferably, from any of the above solutions, the depth of the storage groove is equal to the length of the plugging plate. The plugging plate is located above the brake test structure body.

[0012] Preferably, from any of the above solutions, a bolt is fixedly connected to the outer surface of the plugging plate. A bolt hole is formed on the inner wall of the avoidance groove. The bolt is slidably connected to the lifting plate through the bolt hole.

[0013] Compared with the prior art, the advantages and beneficial effects of the present utility model are as follows:

[0014] 1. When brake inspection is required, the motor can be turned on to drive the lead screw to rotate. Through screw transmission, the drive plate can be driven to slide on the inner wall of the frame. Through the transmission of the connecting plate, the plugging plate can be driven to retract into the storage groove. At this time, the detection end of the brake inspection structure body will be exposed. Then, drive the vehicle to move above the avoidance groove, and then drive the lifting plate to move downward through the hydraulic cylinder. At this time, the guide plate will slide relative to the guide rod, which can limit the lifting of the lifting plate. After the lifting plate moves downward to an appropriate position, the vehicle wheel will contact the detection end of the brake inspection structure body, and brake inspection operations can be carried out. Since the top surface of the lifting plate is on the same horizontal plane as the top surface of the concrete road surface, there is no need to use an inclined plate to guide, which can prevent the vehicle from skidding when driving onto the inspection platform.

[0015] 2. After the brake inspection operation is completed, turn on the hydraulic cylinder to drive the lifting plate to move upward. Through the lifting plate, the wheel can be driven to move upward, so that the wheel can be separated from the brake inspection structure body. After the lifting plate is on the same horizontal plane as the top surface of the concrete road surface, start the vehicle and drive away. Finally, turn on the motor to drive the plugging plate to extend out of the storage groove. After the bolt is inserted into the jack hole, the avoidance groove can be plugged, and the brake inspection structure body can be blocked, which can prevent external dust and sundries from entering the brake inspection structure body. This not only reduces the frequency of dust cleaning, but also does not affect the inspection efficiency and accuracy. Description of the Drawings

Detailed implementation manners

[0023] The following further describes the present utility model in conjunction with the accompanying drawings, but the protection scope of the present utility model is not limited to the following.

[0024] As Figures 1 to 6 shown, an automotive loading brake inspection bench includes a concrete road surface 1. An embedding groove 2 is formed on the top surface of the concrete road surface. A metal frame 3 is fixedly connected inside the embedding groove 2 by bolts. The inner wall of the metal frame 3 is slidably connected with a bottom plate 4. The bottom plate 4 is fixedly connected to the concrete road surface 1 by bolts. A plurality of hydraulic cylinders 5 are fixedly connected to the top surface of the bottom plate 4. The output ends of the plurality of hydraulic cylinders 5 are fixedly connected with a lifting plate 8. An avoidance groove 9 is formed on the top surface of the lifting plate 8. A brake inspection structure body 10 is fixedly installed on the top surface of the bottom plate 4. The brake inspection structure body 10 is slidably connected with the lifting plate 8 through the avoidance groove 9. A frame 11 is fixedly connected to the bottom surface of the lifting plate 8. A motor 12 is fixedly connected to the outside of the frame 11. The output end of the motor 12 is fixedly connected with a lead screw 13. A driving plate 14 is threadedly connected to the outer surface of the lead screw 13. The driving plate 14 is slidably connected with the frame 11. A storage groove 15 is formed on the inner wall of the avoidance groove 9. A plugging plate 16 is slidably connected inside the storage groove 15. The plugging plate 16 is slidably connected with the lifting plate 8 through the avoidance groove 9. A connecting plate 17 is fixedly connected to the bottom surface of the plugging plate 16. The bottom surface of the connecting plate 17 is fixedly connected to the driving plate 14.

[0025] As an alternative technical solution of the present utility model, the lifting plate 8 is parallel to the bottom plate 4, and the lifting plate 8 is slidably connected with the metal frame 3. The setting of the metal frame 3 can prevent the lifting plate 8 from directly contacting the embedding groove 2, and can prevent the damage of the concrete road surface 1 caused by friction.

[0026] As an alternative technical solution of the present utility model, a guiding plate 18 is connected to the bottom surface of the lifting plate 8. A guiding rod 19 is fixedly connected to the side surface of the brake inspection structure body 10 in an embedded manner. The guiding plate 18 is slidably connected with the guiding rod 19. When the hydraulic cylinder 5 drives the lifting plate 8 to move downward, at this time, the guiding plate 18 will slide relative to the guiding rod 19, and the lifting and lowering of the lifting plate 8 can be limited.

[0027] As an alternative technical solution of the present utility model, a limiting post 20 is fixedly connected to the inner wall of the frame 11. The driving plate 14 is slidably connected to the limiting post 20. The limiting post 20 can guide the movement of the driving plate 14, so that the driving plate 14 can slide more stably inside the frame 11.

[0028] As an alternative technical solution of the present utility model, a connecting groove 21 is formed in the bottom surface of the lifting plate 8. The connecting groove 21 communicates with the storage groove 15. The connecting plate 17 is slidably connected to the lifting plate 8 through the connecting groove 21. The transmission of the connecting plate 17 can drive the blocking plate 16 to retract into the storage groove 15. At this time, the detection end of the braking inspection structure body 10 will be exposed.

[0029] As an alternative technical solution of the present utility model, the depth of the storage groove 15 is equal to the length of the blocking plate 16. The blocking plate 16 is located above the braking inspection structure body 10. When the motor 12 is turned on to drive the blocking plate 16 to extend out of the storage groove 15 until the plug pin 22 is inserted into the jack 23, the avoidance groove 9 can be blocked, and the braking inspection structure body 10 can be shielded, preventing external dust and debris from entering the braking inspection structure body 10.

[0030] As an alternative technical solution of the present utility model, a plug pin 22 is fixedly connected to the outer surface of the blocking plate 16. A jack 23 is formed in the inner wall of the avoidance groove 9. The plug pin 22 is slidably connected to the lifting plate 8 through the jack 23. The setting of the plug pin 22 can make the connection between the blocking plate 16 and the lifting plate 8 more stable.

[0031] An automobile load braking inspection bench has the following working principle:

[0032] 1): When braking inspection is required, the motor 12 can be turned on to drive the lead screw 13 to rotate. Through screw thread transmission, the driving plate 14 can be driven to slide on the inner wall of the frame 11. Through the transmission of the connecting plate 17, the blocking plate 16 can be driven to retract into the storage groove 15. At this time, the detection end of the braking inspection structure body 10 will be exposed.

[0033] 2): Drive the vehicle to move above the avoidance groove 9, and then drive the lifting plate 8 to move downward through the hydraulic cylinder 5. At this time, the guide plate 18 will slide relative to the guide rod 19, which can limit the lifting of the lifting plate 8. After the lifting plate 8 moves downward to a suitable position, the vehicle wheel will contact the detection end of the braking inspection structure body 10, and the braking inspection operation can be carried out.

[0034] 3) After the braking inspection operation is completed, the hydraulic cylinder 5 is activated to drive the lifting plate 8 to move upward. The lifting plate 8 can drive the wheel to move upward, enabling the wheel to disengage from the braking inspection structure body 10. After the top surface of the lifting plate 8 is on the same horizontal plane as the top surface of the concrete road surface 1, the vehicle is started and driven away. Finally, the motor 12 is activated to drive the plugging plate 16 to extend out of the storage groove 15. After the plug pin 22 is inserted into the jack 23, the avoidance groove 9 can be plugged.

[0035] In summary, for this vehicle loading braking inspection bench, when braking inspection is required, the motor 12 can be activated to drive the lead screw 13 to rotate. Through screw drive, the drive plate 14 can be driven to slide on the inner wall of the frame 11. Through the transmission of the connecting plate 17, the plugging plate 16 can be driven to retract into the storage groove 15. At this time, the detection end of the braking inspection structure body 10 will be exposed. Then, the vehicle is driven to move above the avoidance groove 9. Subsequently, the hydraulic cylinder 5 drives the lifting plate 8 to move downward. At this time, the guide plate 18 will slide relative to the guide rod 19, which can limit the lifting of the lifting plate 8. After the lifting plate 8 moves downward to an appropriate position, the vehicle wheel will contact the detection end of the braking inspection structure body 10, and the braking inspection operation can be carried out. Since the top surface of the lifting plate 8 is on the same horizontal plane as the top surface of the concrete road surface 1 and there is no need to rely on an inclined plate for guidance, it can prevent the vehicle from skidding when driving onto the inspection bench. After the braking inspection operation is completed, the hydraulic cylinder 5 is activated to drive the lifting plate 8 to move upward. The lifting plate 8 can drive the wheel to move upward, enabling the wheel to disengage from the braking inspection structure body 10. After the top surface of the lifting plate 8 is on the same horizontal plane as the top surface of the concrete road surface 1, the vehicle is started and driven away. Finally, the motor 12 is activated to drive the plugging plate 16 to extend out of the storage groove 15. After the plug pin 22 is inserted into the jack 23, the avoidance groove 9 can be plugged, and the braking inspection structure body 10 can be blocked, preventing dust and debris from the outside from entering the braking inspection structure body 10. This not only reduces the frequency of dust cleaning but also does not affect the inspection efficiency and accuracy.
