[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] See Figures 1-5 This utility model provides the following two technical solutions:

[0030] First implementation: A vehicle chassis clearance inspection bench, comprising:

[0031] Maintenance base 1, with four casters 9 fixedly installed at the bottom of maintenance base 1, is used to support the vehicle and personnel;

[0032] Inspection slot 2 is located in the middle of inspection base 1. Inspection slot 2 is used to accommodate maintenance personnel, making it convenient for staff to inspect the clearance of the car chassis.

[0033] Four jacks 3 are fixedly installed on the left and right ends of the top of the maintenance base 1. The jacks 3 are used to lift the car smoothly, so that the chassis is off the ground, leaving enough operating space for the staff.

[0034] Two first adjusting components 4 and two second adjusting components 5 are installed on the top of the maintenance base 1. Each of the two first adjusting components 4 includes a first mounting block 41. A first bidirectional lead screw 42 is rotatably mounted inside the first mounting block 41. Jack bases 43 are fixedly mounted at both ends of the first bidirectional lead screw 42. Two first sliding grooves 44 are formed on the top of the first mounting block 41. The two jack bases 43 are slidably mounted within the two first sliding grooves 44. A jack 3 is fixedly mounted on the top of each of the two jack bases 43. A first... The motor 45 has its output end fixedly connected to the first bidirectional lead screw 42. The two second adjustment components 5 include lead screws 51, which are rotatably installed in the maintenance base 1. The first mounting block 41 is threaded onto the lead screw 51. The top of the maintenance base 1 has a second sliding groove 52, and the first mounting block 41 is slidably installed in the second sliding groove 52. The end of the maintenance base 1 is fixedly installed with a second motor 53, the output end of which is fixedly connected to the lead screw 51. The two first adjustment components 4 are used to adjust the longitudinal position of the jack 3, and the two second adjustment components 5 are used to adjust the lateral position of the jack 3.

[0035] Two height adjustment components 6 are installed at the two first adjustment components 4 respectively. The height adjustment components 6 are used to control the support height of the jack 3.

[0036] The maintenance base 1 serves as the basic load-bearing structure. Four casters 9 mounted on its bottom allow for overall equipment movement, facilitating flexible position adjustments under vehicles. Four jacks 3 are distributed at both ends of the top of the maintenance base 1, with their support height controlled by a height adjustment assembly 6. When a vehicle enters the maintenance base 1, the jacks 3 activate, lifting the chassis off the ground to provide operating space for personnel. Each first adjustment assembly 4 includes a first bidirectional lead screw 42, driven to rotate by a first motor 45. The threads at both ends of the first bidirectional lead screw 42 have opposite directions, causing the jack bases 43 on both sides to move synchronously inward or outward along the first sliding groove 44. The jack 3 can be adjusted in the front-to-back direction to accommodate different wheelbase models. The lead screw 51 of the second adjustment component 5 is driven by the second motor 53. The first mounting block 41 is threaded onto the lead screw 51. When the lead screw 51 rotates, the first mounting block 41 moves along the second slide groove 52 in the left-to-right direction, causing the jack 3 to move laterally as a whole, thus accommodating different wheelbase models. The inspection slot 2 in the middle of the inspection base 1 is a sunken structure, allowing workers to stand or squat in the slot and observe the chassis components closely from directly below the chassis. They can measure the gaps using tools such as feeler gauges and dial indicators, avoiding the inconvenience of traditional inspections that require crawling under the vehicle.

[0037] In this embodiment, the inspection slot 2 provides ample operating space for workers, eliminating the need for them to bend over or crawl under the vehicle, thus reducing the risk of back strain and bumps. This design is ergonomic. Furthermore, the workers' line of sight is perpendicular to the inspection point, reducing measurement errors compared to traditional methods. The first adjustment component 4 and the second adjustment component 5 are compatible with various vehicle models, including sedans, SUVs, and light trucks, reducing the number of equipment models and lowering equipment procurement costs for automakers or repair shops.

[0038] The second embodiment differs from the first embodiment in that: both height adjustment components 6 include a rotating rod 61, which is rotatably mounted on the top of the first mounting block 41. A slider 62 is fixedly mounted on the rotating rod 61, and two second bidirectional lead screws 63 are slidably mounted on the rotating rod 61 through the slider 62. Four jacks 3 are threaded onto the four second bidirectional lead screws 63 respectively. A third motor 64 is fixedly mounted on the top of the first mounting block 41, and the output end of the third motor 64 is fixedly connected to the rotating rod 61.

[0039] Four hydraulic presses 7 are fixedly installed on the top of the maintenance base 1. The output ends of the four hydraulic presses 7 all pass through the maintenance base 1 and are fixedly installed on the support base 8.

[0040] A control panel 10 is fixedly installed on the maintenance base 1. The control panel 10 is located inside the maintenance slot 2. The first motor 45, the second motor 53, the third motor 64 and the hydraulic press 7 are all electrically connected to the control panel 10.

[0041] The third motor 64 drives the rotating rod 61 to rotate, and the slider 62 on the rotating rod 61 rotates synchronously with the rotating rod 61. Since the slider 62 is slidably connected to the second double-acting lead screw 63, the rotation of the rotating rod 61 will drive the second double-acting lead screw 63 to rotate. The threads at both ends of the second double-acting lead screw 63 have opposite directions. When the second double-acting lead screw 63 moves axially, the jacks 3 at both ends rise or fall synchronously through the threaded connection, realizing precise adjustment of the support height of the car chassis. The slider 62 allows the two jacks 3 on the rotating rod 61 to move with the adjustment of the first adjustment component 4. At the same time, the two height adjustment components... 6. By linking the same rotating rod 61, ensure that the lifting height of the two jacks 3 on the same side is consistent to avoid tilting the car; the piston rod of the hydraulic press 7 extends downward, pushing the support base 8 to contact the ground, and using the high rigidity of the hydraulic system, the maintenance base 1 is supported and fixed as a whole; at this time, the casters 9 are off the ground, forming a rigid support structure to prevent the equipment from moving or shaking during maintenance; the control panel 10 integrates the start / stop and parameter setting functions of the first motor 45, the second motor 53, the third motor 64 and the hydraulic press 7. The staff can input commands through the panel buttons or touch screen to realize the coordinated action of multiple components.

[0042] In this embodiment, the integrated design of the height adjustment component 6, the hydraulic support system, and the control panel 10 greatly enhances the intelligence and safety of the inspection platform. In actual operation, when the staff inputs the vehicle model or custom adjustment parameters, the control panel 10 will synchronously control the first motor 45, the second motor 53, and the third motor 64 to work together according to the preset algorithm. At the same time, the integrated control of the control panel 10 also has fault warning and emergency response functions. When an overload of a motor, abnormal hydraulic pipeline pressure, or asynchronous lifting of the jack 3 is detected, the system will immediately trigger an audible and visual alarm and automatically stop the operation of the relevant components.

[0043] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0044] In use, push the inspection base 1 and use the four casters 9 at the bottom to move the inspection platform under the vehicle to be inspected, adjusting its position so that the inspection slot 2 is precisely aligned with the center of the car chassis. Operate on the control panel 10 inside the inspection slot 2 to start the four hydraulic presses 7. The piston rods of the hydraulic presses 7 extend, pushing the support base 8 to contact the ground until the casters 9 are completely off the ground, forming a stable and rigid support structure for the equipment. Input the wheelbase and track data of the vehicle to be inspected into the control panel 10, or call the preset vehicle parameters. The first motor 45 drives the first double-acting screw 42 to rotate, driving the jack base 43 to move along a slide, adjusting the front and rear distance of the jack 3 to match the vehicle's wheelbase. The second motor 53 drives the screw 51. Rotation causes the first mounting block 41 to move laterally along the second slide groove 52, displacing the jack 3 to match the vehicle's wheel track. After confirming that the jack 3 is aligned with the chassis support point, the third motor 64 is started via the control panel 10. The third motor 64 drives the rotating rod 61 to rotate, and the slider 62 on the rotating rod 61 drives the second double-acting screw 63 to rotate, causing the jacks 3 at both ends to rise synchronously and lift the car chassis off the ground. In the inspection slot 2, the operator uses feeler gauges, dial indicators, and other tools to inspect the clearances of components such as the suspension system, steering system, and transmission system from directly below the chassis. If it is necessary to adjust the inspection angle or depth, the angle of the jack 3 can be finely adjusted or the position of the jack 3 can be slightly moved via the control panel 10.

[0045] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
