Description

Technical Field

[0001] The present invention relates to the technical field of vehicle detection, and in particular to a wheel limiting device for vehicle detection. Background Technique

[0002] Vehicle detection is an inspection to determine the technical condition or working ability of a vehicle. During the use of a vehicle, as the usage time extends (or the driving mileage increases), its parts gradually wear, corrode, deform, age, and the lubricating oil deteriorates, etc., resulting in an increase in the clearance of mating pairs, causing looseness in movement, vibration, rattling, air leakage, water leakage, oil leakage, etc., and causing a decline in the technical performance of the vehicle. The core of vehicle maintenance operations (or vehicle servicing operations) is to "maintain" the good technical condition of the vehicle.

[0003] Generally, a vehicle needs to be inspected annually. When the vehicle is being inspected, it usually needs to be reversed onto the inspection platform for inspection. Since the inspection is carried out indoors, the environment is small and relatively complex. Therefore, it is not easy to control the progress of reversing during reversing, and it is easy to reverse excessively and not accurately park at the inspection position. It is not convenient for the driver to judge in time. For this reason, we have proposed a wheel limiting device for vehicle detection. Summary of the Invention

[0004] The purpose of the present invention is to provide a wheel limiting device for vehicle detection to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A wheel limiting device for vehicle detection includes a ramp platform. One side of the ramp platform is provided with a detection base. One side of the detection base is provided with a groove. A positioning shaft is arranged inside the groove. A baffle is movably sleeved outside the positioning shaft. A rotating shaft is rotatably arranged at the bottom of the baffle. Two rollers are sleeved outside the rotating shaft. A telescopic frame is movably sleeved inside the baffle. An airbag is arranged between the telescopic frame and the baffle. An alarm whistle communicated with the airbag is arranged on the telescopic frame.

[0007] Preferably, two placement grooves are opened at the top of the detection base, and two vehicle placement rollers are rotatably arranged inside the placement grooves.

[0008] Preferably, the baffle is of an L-shaped structure. A U-shaped groove is opened at the bottom of the baffle, and the rotating shaft is rotatably arranged in the U-shaped groove.

[0009] Preferably, the telescopic frame includes two movable rods. One end of each movable rod is provided with a pressing plate. The end of the movable rod far from the pressing plate is fixedly connected with a telescopic plate. A spring sleeved outside the movable rod is connected between the telescopic plate and the baffle.

[0010] Preferably, two moving holes are formed in the baffle, and the moving rod is movably sleeved in the moving holes.

[0011] Preferably, ventilation holes are formed in the telescopic plate, and the airbag is communicated with the alarm whistle through the ventilation holes.

[0012] Compared with the existing technology, the beneficial effects of the present invention are as follows: The present invention limits the wheels through the baffle, and the wheels will squeeze the telescopic frame, which can drive the airbag to expand and contract, thereby sucking and driving the airflow to blow the alarm whistle to remind the driver. Moreover, after the baffle is squeezed, it can be turned and tilted. When the baffle relies on the rollers to turn, it can lift and tilt the detection base, further reminding the staff. The structure of this solution is simple and novel. When reversing too much, it is convenient to use the alarm whistle to remind the driver, and the detection base will tilt up, bringing a more intuitive feeling to the driver, so as to remind the driver to correct the misalignment in time and park the vehicle accurately.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Refer to Figures 1-4, A wheel limiting device for vehicle detection, comprising a ramp platform 1. On one side of the ramp platform 1, there is a detection base 2. On one side of the detection base 2, there is a groove 5. Inside the groove 5, there is a positioning shaft 6. An outer movable sleeve of the positioning shaft 6 is provided with a baffle 7. At the bottom of the baffle 7, a rotating shaft 8 is rotatably provided. An outer sleeve of the rotating shaft 8 is provided with two rollers 9. An inner movable sleeve of the baffle 7 is provided with a telescopic frame. Between the telescopic frame and the baffle 7, there is an airbag 14. On the telescopic frame, there is an alarm whistle 15 communicated with the airbag 14. When the vehicle reverses, the wheel will squeeze the telescopic frame. In this way, the telescopic frame will pull the airbag 14, and the airbag 14 will inhale air and sound the alarm whistle 15 through the airflow to give an alarm reminder. At the same time, continuing to reverse will exert pressure on the baffle 7. In this way, the baffle 7 will flip and lift the entire detection base 2, so as to more obviously remind the driver to correct the misalignment in time.

[0020] As Figure 2 shown, on the top of the detection base 2, two placement grooves 3 are opened. Inside the placement grooves 3, two vehicle placement rollers 4 are rotatably provided. The vehicle placement rollers 4 are used to park the wheels in the detection position.

[0021] As Figure 4 shown, the baffle 7 is of an L-shaped structure. At the bottom of the baffle 7, a U-shaped groove is opened, and the rotating shaft 8 is rotatably arranged in the U-shaped groove. The baffle 7 rotates on the positioning shaft 6 and can pry up the detection base 2 through the rollers 9.

[0022] As Figure 2 shown, the telescopic frame includes two movable rods 10. At one end of the movable rod 10, there is a pressing plate 11. At the end of the movable rod 10 far from the pressing plate 11, a telescopic plate 12 is fixedly connected. Between the telescopic plate 12 and the baffle 7, there is a spring 13 sleeved outside the movable rod 10. The spring 13 will pull the telescopic plate 12 and the airbag 14 to reset.

[0023] As Figure 4 shown, two movable holes are opened on the baffle 7, and the movable rod 10 is movably sleeved in the movable holes. The movable rod 10 can telescopically move in the movable holes.

[0024] As Figure 2 shown, ventilation holes are opened on the telescopic plate 12, and the airbag 14 is communicated with the alarm whistle 15 through the ventilation holes.

[0025] Working principle: First, when the vehicle reverses from the ramp platform 1 and drives onto the detection base 2, the front and rear wheels are respectively parked on the vehicle placement rollers 4 to complete the accurate parking of the vehicle. If the reverse is excessive, a slight excess will cause the vehicle to squeeze the extrusion plate 11. The extrusion plate 11 drives the telescopic plate 12 to move through the movable rod 10. The telescopic plate 12 will stretch the airbag 14. When the airbag 14 is stretched, it will inhale air, and thus an alarm whistle 15 can be sounded through the inhaled air flow to give an alarm reminder. If the driver continues to reverse without noticing the alarm sound, the wheel will squeeze the baffle 7 through the extrusion plate 11. When the baffle 7 is squeezed, it will flip around the positioning shaft 6 and will be supported by the roller 9 when flipping, which will pry up the detection base 2, thus tilting the entire wheel, giving the driver an intuitive feeling, so as to remind the driver to correct the misalignment in time and park the vehicle accurately without the need for others to remind.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
