Description

Technical Field

[0001] This invention relates to the field of motor vehicle testing equipment technology, and in particular to a testing device and testing method for motor vehicle testing. Background Technology

[0002] Motor vehicles, abbreviated as motor vehicles, are wheeled vehicles that are driven or towed by their own power unit and can travel on land without tracks. They generally refer to vehicles that travel on roads for riding or (and) transporting goods or performing special operations, including automobiles, trailers, handcarts, agricultural transport vehicles, motorcycles, motorized tricycles and transport tractors, as well as wheeled special machinery vehicles, but do not include any vehicles that travel on tracks.

[0003] When a motor vehicle malfunctions, it needs to be taken to a repair shop for inspection and maintenance. Inspection and maintenance typically involve the vehicle's chassis, requiring inspection equipment to lift the vehicle to facilitate access for personnel. However, existing lifting inspection equipment suffers from several problems: its overall adjustability is very poor, generally lacking rotation adjustment capabilities, requiring operators to manually rotate the equipment to accommodate the chassis during inspection and maintenance. Furthermore, lifting is inherently dangerous, as malfunctions can cause the vehicle to fall, posing a significant threat to the inspection and maintenance personnel. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology by proposing a testing device and method for motor vehicle testing. It adopts a combination of a mounting plate, an adjustable double-threaded rod, an adjustment mechanism, a connecting mechanism, a side plate, a sliding rod, an elastic mechanism, and a limiting mechanism. It uses two adjustable mounting plates to accommodate the placement of motor vehicles and the side plates driven by springs to achieve stable placement of the motor vehicle on both sides, thus ensuring the applicability of the device and the stability of the motor vehicle placement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vehicle inspection device includes a support ring with an annular groove on its upper surface. Multiple movable blocks are arranged within the annular groove via a stabilizing mechanism. An extension block is fixedly mounted on the arc-shaped outer wall of the support ring. A rotating groove is provided on the side wall of the extension block. A rotating gear is rotatably mounted on the bottom wall of the rotating groove. The rotating gear is connected to the multiple movable blocks via a rotating mechanism. A support frame is fixedly mounted on the upper surface of one of the movable blocks. A lifting groove is provided on the side wall of the support frame. A lifting threaded rod is rotatably mounted within the lifting groove. A lifting nut is provided on the outer wall of the lifting threaded rod. A lifting plate is fixedly connected to the outer wall of the lifting nut. Two rotating grooves are provided on the upper surface of the lifting plate. An adjusting double-headed threaded rod is rotatably mounted within both rotating grooves. Two mounting plates are provided on the upper surface of the lifting plate and connected to the adjusting double-headed threaded rod via an adjusting mechanism. Each mounting plate has a movable groove and a side plate on its upper surface. A sliding rod is fixedly mounted within the movable groove. The side plate is connected to the sliding rod via a connecting mechanism and to the mounting plate via a limiting mechanism.

[0007] Stabilizing rods are fixedly provided on the upper surfaces of the two movable blocks. Stabilizing plates that cooperate with the stabilizing rods are fixedly provided on the outer walls of both sides of the lifting plate. An active chamber is provided inside the stabilizing plate. A double-headed threaded rod is rotatably provided in the active chamber. Two clamping bars for clamping the stabilizing rod are provided in the active chamber through a limiting mechanism. Clamping nuts connected to the clamping bars are provided on the outer walls of both ends of the double-headed threaded rod.

[0008] The bottom wall of the lifting plate is equipped with a drive motor, and the lifting plate is equipped with a transmission chamber. The transmission chamber is equipped with a drive gear connected to the drive motor, and the end of the clamping double-threaded rod extends into the transmission chamber and is connected to the drive gear through a transmission mechanism.

[0009] Preferably, the stabilizing mechanism is provided by a stabilizing ring fixedly disposed on the bottom wall of the annular groove, and the bottom walls of the multiple movable blocks are provided with stabilizing grooves corresponding to the stabilizing rings.

[0010] Preferably, the rotating mechanism includes a gear ring that is fixedly connected to multiple movable blocks, and the rotating gear meshes with the gear ring.

[0011] Preferably, the adjusting mechanism includes an adjusting nut threaded onto the outer wall of the adjusting double-ended threaded rod, and the bottom wall of the mounting plate is fixedly connected to the outer wall of the adjusting nut.

[0012] Preferably, the connecting mechanism includes a sliding sleeve that is slidably sleeved outside the sliding rod, the bottom wall of the side plate is fixedly connected to the outer wall of the sliding sleeve, and a spring is elastically connected between the sliding sleeve and the inner side wall of the movable groove.

[0013] Preferably, the limiting mechanism includes a limiting block disposed on the side plate, and both side walls of the step plate are provided with limiting grooves corresponding to the limiting block.

[0014] Preferably, the limiting mechanism includes a limiting rod fixedly installed inside the activity chamber, the limiting rod sliding through two clamping strips.

[0015] Preferably, the transmission mechanism includes a transmission gear fixedly connected to the end of the clamping double-threaded rod, and the transmission gear meshes perpendicularly with the driving gear.

[0016] This invention also proposes a detection method for a vehicle inspection device, comprising the following steps:

[0017] S1. Adjust the limit switch to adjust the distance between the two ramps according to the size of the vehicle;

[0018] S2. The vehicle enters the parking space. The vehicle drives onto the lifting platform and the two ramps. The side plates driven by the springs achieve lateral stabilization of the vehicle body.

[0019] S3. Lift the vehicle body by using the lifting screw rod to lift the lifting plate, thereby lifting the vehicle body and making it easier for operators to inspect from below the vehicle body.

[0020] S4. Limit protection: The clamping double-headed threaded rod drives the clamping bar assembly to move, thereby clamping and fixing the clamping bar to the stabilizer bar and ensuring the stability of the vehicle body after it is lifted.

[0021] S5. Rotation adjustment: By using a rotating gear and a gear ring, multiple movable blocks can be driven to rotate and move within an annular groove, thereby cooperating with the support frame to realize the rotation operation of the vehicle body, making it convenient for maintenance personnel to carry out maintenance.

[0022] The beneficial effects of this invention are:

[0023] 1. By setting up a mounting plate, adjusting a double-ended threaded rod, adjusting mechanism, connecting mechanism, side plate, sliding rod, elastic mechanism and limiting mechanism, etc., the device can adapt to the placement of motor vehicles by using two mounting plates with easily adjustable spacing. The side plates driven by springs can achieve stable placement on both sides of the motor vehicle, ensuring the applicability of the device and the stability of the motor vehicle placement.

[0024] 2. By setting up a rotating gear, a toothed ring, and multiple movable blocks, the rotating gear can drive the toothed ring to rotate, thereby realizing the rotation operation of multiple movable blocks and support frames and other components. This enables the vehicle on the lifting plate to be rotated and adjusted relative to the inspection and maintenance personnel, improving the practicality of the device.

[0025] 3. By setting up components such as a stabilizer bar, clamping bars, and a double-threaded clamping rod, the drive motor can drive the active gear to rotate, which in turn drives the double-threaded clamping rod assembly to move the clamping bars closer, thereby achieving a stable clamping and fixing operation of the stabilizer bar. This ensures the stability of the position of the vehicle after the lifting plate lifts it, reducing the probability of it falling. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Reference Figure 1-5 A testing device for motor vehicle testing includes a support ring 1. The upper end face of the support ring 1 is provided with an annular groove 2.

The support ring 1 is also provided with an opening that cooperates with the rotating gear and the annular groove 2, so that the rotating gear can extend into the opening and mesh with the toothed ring 21.

[0035] One of the movable blocks 3 has a support frame 7 fixedly mounted on its upper surface. The support frame 7 has a lifting groove on its side wall, and a lifting threaded rod 8 is rotatably mounted within the lifting groove. A lifting nut is mounted on the outer wall of the lifting threaded rod 8, and a lifting plate 10 is fixedly connected to the outer wall of the lifting nut. Figure 1 The lifting plate 10 has a built-in limit switch, which can drive the lifting nut to achieve the limit switch and prevent it from rotating together with the lifting threaded rod 8;

[0036] The upper end face of the lifting plate 10 is provided with two rotating grooves, and the two rotating grooves are equipped with a double-headed threaded rod 11 that rotates together. The upper end face of the lifting plate 10 is provided with two mounting plates 12 that are connected to the double-headed threaded rod 11 through an adjustment mechanism. The adjustment mechanism includes an adjustment nut that is threaded onto the outer wall of the double-headed threaded rod 11. The bottom wall of the mounting plate 12 is fixedly connected to the outer wall of the adjustment nut.

[0037] Both upper surfaces of the two mounting plates 12 are provided with movable grooves and side plates 15. A sliding rod 13 is fixedly installed in the movable groove. The side plate 15 is connected to the sliding rod 13 through a connecting mechanism. The connecting mechanism includes a sliding sleeve 14 that is slidably sleeved on the outside of the sliding rod 13. The bottom wall of the side plate 15 is fixedly connected to the outer wall of the sliding sleeve 14. A spring is elastically connected between the sliding sleeve 14 and the inner side wall of the movable groove.

[0038] The side plate 15 is connected to the platform 12 through a limiting mechanism. The limiting mechanism includes a limiting block 17 on the side plate 15. Both sides of the platform 12 are provided with limiting grooves 16 corresponding to the limiting block 17.

[0039] Stabilizing rods 18 are fixedly mounted on the upper surfaces of the two movable blocks 3. Stabilizing plates 19, which cooperate with the stabilizing rods 18, are fixedly mounted on the outer walls of both sides of the lifting plate 10.

Two clamping strips 25 for clamping the stabilizing rod 18 are provided within the movable chamber 22 via a limiting mechanism. The limiting mechanism includes a limiting rod 26 fixedly mounted within the movable chamber 22, which slides through the two clamping strips 25. Clamping nuts 24 connected to the clamping strips 25 are provided on the outer walls at both ends of the double-ended threaded rod 23. A drive motor 20 is provided on the bottom wall of the lifting plate 10. A transmission chamber 27 is provided inside the lifting plate 10. A drive motor 20 is provided within the transmission chamber 27. The motor 20 is connected to the drive gear 28, which holds the end of the double-ended threaded rod 23 and extends into the transmission chamber 27 and is connected to the drive gear 28 through the transmission mechanism. The transmission mechanism includes a transmission gear 29 fixedly connected to the end of the double-ended threaded rod 23. The transmission gear 29 meshes perpendicularly with the drive gear 28. After the lifting plate 10 lifts the motor vehicle, the drive motor 20 needs to be started. The drive motor 20 can drive the drive gear 28 to rotate. The drive gear 28 can drive the double-ended threaded rod 23 to rotate with the help of the transmission gear 29. When the double-ended threaded rod 23 rotates, the clamping nut 24 on its outer wall can drive the clamping bar 25 to move, thereby realizing the clamping and fixing operation on the outer wall of the stabilizer bar 18.

[0040] This invention also proposes a detection method for a vehicle inspection device, comprising the following steps:

[0041] S1. Adjust the limit switch to adjust the distance between the two ramps 12 according to the size of the vehicle;

[0042] S2. The vehicle is positioned and the vehicle is driven onto the lifting platform 10 and the two ramps 12. The side plates 15 driven by the springs achieve lateral stabilization of the vehicle body.

[0043] S3. Lift the vehicle body by using the lifting threaded rod 8 to lift the lifting plate 10, thereby lifting the vehicle body and making it easier for the operator to be under the vehicle body for inspection.

[0044] S4. Limit protection: The clamping double-headed threaded rod 23 drives the clamping bar 25 assembly to move, thereby clamping and fixing the clamping bar 25 to the stabilizer bar 18 and ensuring the stability of the vehicle body after it is lifted.

[0045] S5. Rotation adjustment: With the help of the rotating gear and the gear ring 21, multiple movable blocks 3 can be driven to rotate and move in the annular groove 2, thereby cooperating with the support frame 7 to realize the rotation operation of the vehicle body, which is convenient for maintenance personnel to carry out maintenance.

[0046] In use, the lifting plate 10 and the mounting plate 12 are initially at their lowest position, with the bottom of the lifting plate 10 in contact with one of the movable blocks 3. First, the distance between the two mounting plates 12 is adjusted according to the distance between the front and rear wheels of the vehicle, so that the front and rear wheels are positioned on either side of the mounting plates 12. The vehicle chassis rests on the two mounting plates 12. Multiple side plates 15 are brought closer together by the elastic potential energy provided by springs, ensuring the stability of the vehicle's placement. The elastic potential energy of the springs is sufficiently large. Then, the lifting motor 9 is activated, which drives the lifting threaded rod 8 to rotate. At this time, the lifting nut, with the help of the lifting plate 10 and other components, lifts the vehicle upwards, forming... Figure 1 In this state, inspection and maintenance personnel can perform inspection and maintenance operations on the vehicle chassis from below the lifting plate 10.

[0047] After the lifting plate 10 lifts the vehicle, the drive motor 20 needs to be started. The drive motor 20 can drive the drive gear 28 to rotate. The drive gear 28 can drive the clamping double-headed threaded rod 23 to rotate through the transmission gear 29 that cooperates with it. When the clamping double-headed threaded rod 23 rotates, the clamping nut 24 on its outer wall can drive the clamping bar 25 to move, so as to realize the clamping and fixing operation on the outer wall of the stabilizer bar 18, ensuring the stability of the state after the lifting plate 10 and other components lift the vehicle, and reducing the probability of its falling accident.

[0048] Among them, the rotating motor 6 can drive the rotating gear inside the extension block 5 to rotate. The rotating gear can drive multiple movable blocks 3, support frame 7 and other components to rotate through the gear ring 21, thereby realizing the rotation adjustment of the motor vehicle relative to the inspection and maintenance personnel, which facilitates the inspection and maintenance personnel to perform multi-directional inspection and maintenance operations on the motor vehicle chassis.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
