Description

Technical Field

[0001] This invention relates to the field of vehicle inspection device technology, and specifically to a used car damage detection platform. Background Technology

[0002] In the used car inspection and evaluation industry, identifying structural damage, chassis dents, rust, and repair marks is crucial. Currently, common inspection methods mainly rely on two types of equipment: traditional pit-type inspection platforms and fixed four-post lift platforms.

[0003] Traditional trenches require underground excavation, which is costly and time-consuming. Once built, they cannot be moved and have poor flexibility. They also suffer from poor ventilation and lighting, and cramped working spaces.

[0004] While a four-post lift can raise a vehicle entirely off the ground, the vehicle is usually kept level after being lifted, obstructing the view of inspectors when looking up to check the chassis. Furthermore, when disassembling or inspecting certain components, it may be necessary to maintain a certain tilt angle. Existing conventional lifts lack safe and reliable lateral tilting and locking functions. Using auxiliary support devices is cumbersome and carries the risk of slippage and tipping. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a used car damage detection platform. This device has a reasonable structural design, is flexible and safe to operate, and can achieve safe vehicle tilting, thereby improving the convenience of detection and repair.

[0006] A used car damage detection platform includes two wheel support platforms distributed in a left-right direction, a personnel support plate and several lifting devices arranged between the two wheel support platforms, and the personnel support plate is connected to the output shaft of all the lifting devices.

[0007] Preferably, it also includes a top plate, a left support frame, a right support frame, and multiple support column groups distributed along the front-to-back direction;

[0008] The support column assembly includes two support columns, located on the left and right sides of two wheel support platforms, respectively. Each support column has an open-topped groove on its side wall, within which a slider is slidably mounted. A steel cable connects two sliders. A top plate is fixed to the top of multiple support columns and has several electric motors mounted on it, each corresponding to a support column. A lifting steel cable is connected to the output shaft of each electric motor, entering from the top of the groove and connecting to the slider.

[0009] The left support frame is located to the left of the left support column. Several left drive cylinders are fixed on the left support frame. The output shaft of each left drive cylinder is connected to a left support plate. The left support plate is covered with a sponge layer. Each left support plate is located between two left support columns.

[0010] The right support frame is located to the right of the right support column. Several right drive cylinders are fixed on the right support frame. The output shaft of the right drive cylinder is connected to the right stop column. Each right stop column is located between two right support columns.

[0011] Preferably, the support column group is configured as three, and the three support column groups are distributed at equal intervals.

[0012] Preferably, there are two left-hand drive cylinders.

[0013] Preferably, there are two right-hand drive cylinders.

[0014] Preferably, the rear wall of the wheel support platform is inclined.

[0015] Preferably, the lifting device is a lifting cylinder.

[0016] Preferably, the lifting device is configured as four, and the four lifting devices are arranged in a rectangular shape.

[0017] The beneficial effects of this invention are reflected in:

[0018] Integrated and installation-free: The platform is a modular steel structure that eliminates the need for digging trenches or complex ground foundation construction. It can be used immediately after placement, saving site modification costs and time.

[0019] The inspection perspective is comprehensive and flexible, enabling multiple inspection postures such as "low horizontal position," "high horizontal position," and "right-side tilt." The tilted position fully exposes the right side of the vehicle chassis to the inspector's upright line of sight, eliminating the need for a difficult supine position and greatly improving inspection conditions and working comfort.

[0020] The core safety mechanism is prominent: the dual stabilization design of "electric lifting cable + mechanical right-side stop column" is key to ensuring safety during tilt detection. The two work together, acting as backups for each other, fundamentally preventing rollover accidents caused by a single mechanism failure when the vehicle is tilted, resulting in a safety factor far exceeding that of ordinary single-support devices.

[0021] Comprehensive vehicle protection measures: A sponge layer is installed on the contact surface of the left support plate to provide support while preventing hard scratches to the vehicle's paint or sheet metal. Attached Figure Description

Detailed Implementation

[0025] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0026] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0027] Example

[0028] like Figure 1 As shown, this embodiment provides a used car damage detection platform, including two wheel support platforms 1 distributed in the left-right direction, a personnel support plate 2 and several lifting devices 3 arranged between the two wheel support platforms 1, and the personnel support plate 2 is connected to the output shaft of all the lifting devices 3.

[0029] In this embodiment, two wheel support platforms 1 are provided, and several lifting devices 3 are provided between the two wheel support platforms 1. A personnel support plate 2 is provided on the output shaft of the lifting device 3. When performing routine inspections, the lifting device 3 drives the personnel support plate 2 to the lowest position, at which time the inspector can lie supine to perform routine inspections on the vehicle chassis.

[0030] This embodiment also includes a top plate 8, a left support frame 11, a right support frame 12, and multiple support column groups distributed along the front-back direction;

[0031] The support column assembly includes two support columns 4, which are located on the left and right sides of the two wheel support platforms 1, respectively. Each support column 4 has a top-opening groove 5 on its side wall. A slider 6 is slidably mounted within the groove 5, and a steel cable 7 connects two sliders 6. A top plate 8 is fixed to the top of the support columns 4, and several electric motors 9 are mounted on the top plate 8. Each electric motor 9 corresponds to one support column 4. A lifting steel cable 10 is connected to the output shaft of each electric motor 9. The lifting steel cable 10 enters from the top of the groove 5 and connects to the slider 6.

[0032] The left support frame 11 is located to the left of the left support column 4. Several left drive cylinders 13 are fixed on the left support frame 11. The output shaft of the left drive cylinder 13 is connected to a left support plate 14. The left support plate 14 is covered with a sponge layer 15. Each left support plate 14 is located between two left support columns 4.

[0033] The right support frame 12 is located to the right of the right support column 4. Several right drive cylinders 16 are fixed on the right support frame 12. The output shaft of the right drive cylinder 16 is connected to the right stop column 17. Each right stop column 17 is located between two right support columns 4.

[0034] When a vehicle requires complex inspections or component replacements, it is inconvenient for repair personnel to operate while lying supine. In such cases, a tilted repair mode can be used. The specific operating procedure is as follows:

[0035] The operator first starts all the motors 9. The motors 9 wind up the lifting steel cable 10, which drives the slider 6 to rise at a constant speed along the slide 5. The load-bearing steel cable 7 connecting the left and right sliders 6 then lifts the vehicle chassis, raising the vehicle smoothly to a height of about 1.5 meters off the ground. At this time, the two left drive cylinders 13 on the left support frame 11 are simultaneously extended, so that the left support plate 14 and its surface sponge layer 15 fit tightly and gently against the left side of the vehicle.

[0036] Next, the electric motor 9 on the right side is selectively controlled to continue slowly lifting, causing the vehicle's center of gravity to shift and the right side of the vehicle to rise, resulting in a tilt of the vehicle chassis. The operator observes and controls the tilt angle of the right side of the vehicle between 15 and 45 degrees. When the predetermined angle is reached, the two right drive cylinders 16 on the right support frame 12 are immediately controlled to move rapidly, pushing the two right abutment pillars 17 to extend horizontally to the left, firmly supporting the right side of the vehicle.

[0037] At this point, the vehicle is in a stable right-side tilt position. The right side is restrained by the lifting cable 10 (still taut) and the mechanical right stop column 17, while the left side is supported and limited by the left support plate 14, forming a stable constraint where three points define a plane. Inspectors can easily stand on the right side of the vehicle, gaining a clear view of the entire right-side chassis, fender lining, and side panel welding points, greatly facilitating inspection, photography, or maintenance. After inspection, the reverse sequence of steps restores the vehicle to a level position and lowers it back onto the wheel support platform 1, allowing for safe removal from the platform.

[0038] In this embodiment, three support column groups are configured, with the three support column groups evenly spaced. These three support column groups, equipped with three load-bearing steel cables 7, provide stronger stability for vehicle support.

[0039] In this embodiment, the left drive cylinder 13 is configured as two.

[0040] In this embodiment, two right drive cylinders 16 are configured. Similarly, two left drive cylinders 13 and two right drive cylinders 16 are also configured. Two left support plates 14 are formed on the left side to provide more stable left-side positioning of the vehicle, and two right abutment pillars 17 are formed on the right side to provide more stable right-side positioning of the vehicle. Furthermore, the left support plates 14 and right abutment pillars 17 are both located between the front and rear support pillars 4, avoiding interference with the rising of the load-bearing steel cable 7.

[0041] In this embodiment, the rear wall of the wheel support platform 1 is inclined to facilitate the vehicle driving onto the wheel support platform 1.

[0042] In this embodiment, the lifting device 3 is a lifting cylinder. The use of a lifting cylinder in this embodiment facilitates control.

[0043] In this embodiment, four lifting devices 3 are provided, and the four lifting devices 3 are arranged in a rectangular shape, which provides stronger support stability for the personnel support plate 2.
