Description

A mobile vehicle inspection line capable of measuring suspension braking Technical Field

[0001] This utility model belongs to the field of automotive testing technology, and in particular relates to a mobile automotive testing line that can measure suspension braking. Background Technology

[0002] The performance of a vehicle's suspension and braking system is directly related to driving safety and ride comfort. Accurately measuring its performance parameters can not only help detect potential faults in a timely manner and ensure road traffic safety, but also provide a scientific basis for vehicle maintenance and performance optimization.

[0003] Traditional vehicle testing lines either rely on large areas for off-site testing, making the process cumbersome and inflexible, or are affected by differences in vehicle wheelbase, meaning most testing equipment can only test the front and rear wheels independently, resulting in low testing efficiency and long processing times.

[0004] To address these issues, we provide a mobile vehicle testing line capable of measuring suspension braking. Summary of the Invention

[0005] The purpose of this invention is to provide a mobile vehicle inspection line that can measure suspension braking. By adjusting the motor to drive the double threaded screw to rotate, the distance between the front and rear sliding frames can be adjusted, which solves the problem that existing vehicle inspection devices are not convenient to adjust according to vehicle models.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a mobile vehicle inspection line that can measure suspension braking. It includes a base, a mobile chassis, a mounting frame and a bottom plate fixed on the top of the mobile chassis, a top plate fixed on the top of the mounting frame, and mounting openings distributed in a rectangular pattern on the top of the top plate. Folding plates for getting on and off the vehicle are provided on both sides of the mounting frame.

[0008] The suspension test assembly includes four sliding frames corresponding to four mounting ports. A fixed plate is fixed on the top of the sliding frame, and an electric cylinder is fixed inside the sliding frame. A fixed frame is movably sleeved at the center of the fixed plate and fixed at the output end of the electric cylinder. Two test rollers are rotatably connected inside the fixed frame, and two parallel sliding groove plates are fixed at the bottom of the fixed frame.

[0009] The adjustable assembly includes an adjusting motor fixed to the top of the base plate, four parallel slide rails, and a connecting frame fixed between two horizontally adjacent sliding frames. The slide plate is slidably connected to the outside of the corresponding slide rail. Threaded sleeves are fixed in the middle of the two sliding frames. Two bearing seats are fixed to the top of the base plate. Double-threaded screws fixed to the output end of the adjusting motor are rotatably connected inside the two bearing seats. The two threaded sleeves are threaded onto the outside of the two threaded portions of the two double-threaded screws, respectively.

[0010] The present invention is further configured such that a control cabinet and a bracket are fixedly mounted on the top of the mobile chassis, and a display is mounted on the outside of the bracket.

[0011] The present invention is further provided with a protective component on the top of the mobile chassis to prevent damage from vehicle collisions.

[0012] The protective assembly includes two uprights fixed to the top of the mounting frame, with the two uprights located on opposite sides of two top plates. Each of the two uprights has a crash plate installed on its opposite side, and multiple evenly distributed buffer springs are fixed between the crash plate and the corresponding upright.

[0013] The present invention is further configured such that the folding plate includes a first inclined plate rotatably connected to the side of the mounting frame, a second inclined plate rotatably connected to the end of the first inclined plate away from the mounting frame, a third inclined plate rotatably connected to the end of the second inclined plate away from the mounting frame, a first hydraulic cylinder rotatably connected to the side of the mounting frame, and the output end of the first hydraulic cylinder rotatably connected to the side of the second inclined plate, the second hydraulic cylinder and the third hydraulic cylinder rotatably connected to the sides of the first and second inclined plates respectively, and the output ends of the second and third hydraulic cylinders rotatably connected to the sides of the second and third inclined plates respectively.

[0014] The present invention is further configured such that two support cylinders with vertically downward output ends are fixedly provided on both sides of the mounting frame, and supports are fixedly provided on the output ends of the four support cylinders.

[0015] The present invention is further provided that the top of the top plate, the first inclined plate, the second inclined plate and the third inclined plate are all covered with anti-slip strips.

[0016] The present invention is further configured such that a buffer pad is fixed on the side of the anti-collision plate away from the upright, and a plurality of evenly distributed energy-absorbing boxes are fixed between the anti-collision plate and the upright.

[0017] The present invention is further configured such that four rectangular angle irons are vertically fixed inside the sliding frame, and the fixing frame is slidably connected to the inside of the four angle irons.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model simulates the driving state of a vehicle on a bumpy road by placing the four wheels of the vehicle inside four fixed frames, starting the vehicle to make the four wheels rotate, and then activating four electric cylinders to extend or retract the output end of the electric cylinders by a corresponding amount, thereby enabling a rapid and comprehensive test of the vehicle's suspension performance.

[0020] 2. This utility model drives the double-threaded screw to rotate by starting the adjustment motor. Then, under the action of the threads, the two threaded sleeves drive the corresponding sliding frame to slide along the slide rail through the two connecting frames. This allows the distance between the front and rear sliding frames to be adjusted according to the vehicle's wheelbase, thus enabling simultaneous testing of the four wheels of different vehicle models and improving testing efficiency.

[0021] 3. This utility model can absorb some kinetic energy through the buffer pad, and then further absorb the vehicle's kinetic energy through the compression spring of the anti-collision plate and the deformation of the energy-absorbing box, thereby avoiding serious damage to the vehicle and ensuring safety during the testing process.

[0022] 4. This utility model, by sequentially activating the first and second hydraulic cylinders, pushes the first and second inclined plates to unfold respectively, and then drives the third inclined plate through the third hydraulic cylinder to complete the gentle slope structure, thereby making it more convenient for the vehicle to be tested to go up and down. By reversing the above operations, the folding plate can be folded, thereby making it more convenient for this utility model to move.

[0023] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0034] 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 skilled in the art without creative effort are within the scope of protection of the present utility model. Embodiments

[0035] Please refer to Figures 1 and 5. This utility model is a mobile vehicle inspection line that can measure suspension braking. It includes a base 100, a mobile chassis 101, a mounting frame 103 and a bottom plate 102 fixed on the top of the mobile chassis 101, a top plate 104 fixed on the top of the mounting frame 103, and a rectangular mounting opening 105 on the top of the top plate 104. Folding plates 300 for getting on and off the vehicle are provided on both sides of the mounting frame 103.

[0036] The suspension test assembly 200 includes four sliding frames 201 corresponding to four mounting ports 105 respectively. A fixed plate 202 is fixedly mounted on the top of the sliding frame 201. An electric cylinder 205 is fixedly mounted inside the sliding frame 201. A fixed frame 203 is movably sleeved at the center of the fixed plate 202 and is fixed to the output end of the electric cylinder 205. Two test rollers 204 are rotatably connected inside the fixed frame 203. Two parallel sliding groove plates 207 are fixedly mounted on the bottom of the fixed frame 203. The extension and retraction of the output end of the electric cylinder 205 can simulate the bumpy road conditions during vehicle operation, thereby enabling the testing of the vehicle's suspension performance.

[0037] The top of the mobile chassis 101 is fixed with a control cabinet 500 and a bracket 108. A display 600 is installed on the outside of the bracket 108. The display 600 can intuitively display the test-related parameters, making the operation more convenient.

[0038] Specifically, two vertically downward-facing support cylinders 106 are fixed on both sides of the mounting bracket 103, and supports 107 are fixed on the output ends of the four support cylinders 106. By extending the output ends of the four support cylinders 106 respectively, the supports 107 are pressed firmly onto the ground, which can increase the stability during the test.

[0039] Furthermore, four rectangular angle irons 206 are vertically fixed inside the sliding frame 201, and the fixing frame 203 is slidably connected to the inside of the four angle irons 206. By sliding the fixing frame 203 inside the four angle irons 206, the movement of the fixing frame 203 can be made more stable.

[0040] The operation process of this embodiment is as follows: When it is necessary to test the suspension performance of a vehicle, firstly, the four wheels of the vehicle are placed inside the four fixed frames 203 respectively. Then, the vehicle is started, causing the four wheels to rotate. Then, by activating the four electric cylinders 205 respectively, the output ends of the electric cylinders 205 extend or retract by a corresponding amount, thereby simulating the driving state of the vehicle on a bumpy road, and thus enabling a rapid and comprehensive test of the vehicle's suspension performance. Example

[0041] Please refer to Figures 1 and 6. Based on the first specific embodiment, the adjustable distance assembly 700 includes an adjusting motor 701 fixed to the top of the base plate 102, four parallel slide rails 702, and a connecting frame 705 fixed between two horizontally adjacent sliding frames 201. The slide plate 207 is slidably connected to the outside of the corresponding slide rail 702. Threaded sleeves 706 are fixed in the middle of each of the two sliding frames 201. Two bearing seats 703 are fixed to the top of the base plate 102. Double-threaded screws 704 fixed to the output end of the adjusting motor 701 are rotatably connected inside the two bearing seats 703. The two threaded sleeves 706 are threaded onto the outside of the two threaded portions of the two double-threaded screws 704. By starting the adjusting motor 701 to drive the double-threaded screws 704 to rotate, the distance between the front and rear sliding frames 201 can be adjusted according to the vehicle's wheelbase, thus adapting to more different vehicle models.

[0042] The operation process of this embodiment is as follows: When it is necessary to measure vehicles with different wheelbases, the adjustment motor 701 is first started to drive the double threaded screw 704 to rotate. Then, under the action of the thread, the two threaded sleeves 706 drive the corresponding sliding brackets 201 to slide along the slide rail 702 through the two connecting frames 705. This allows the distance between the front and rear sliding brackets 201 to be adjusted according to the vehicle's wheelbase, thereby enabling simultaneous testing of the four wheels of different vehicle models and improving testing efficiency. Example

[0043] Please refer to Figures 1 and 7. Based on specific embodiment one and specific embodiment two, the top of the mobile chassis 101 is provided with a protective component 400 for avoiding damage from vehicle collisions.

[0044] The protective assembly 400 includes two uprights 401 fixed to the top of the mounting bracket 103, and the two uprights 401 are respectively located on both sides of the two top plates 104. A crash plate 402 is installed on the opposite side of the two uprights 401. A plurality of evenly distributed buffer springs 403 are fixed between the crash plate 402 and the corresponding upright 401. The contraction of the buffer springs 403 can absorb part of the kinetic energy of the vehicle.

[0045] Specifically, a buffer pad 405 is fixed on the side of the anti-collision plate 402 away from the upright 401, and a plurality of evenly distributed energy-absorbing boxes 404 are fixed between the anti-collision plate 402 and the upright 401. The energy-absorbing boxes 404 can further absorb the kinetic energy of the vehicle by deforming.

[0046] The operation process of this embodiment is as follows: When the vehicle loses control, the buffer pad 405 can absorb some of the kinetic energy. Then, the anti-collision plate 402 compresses the spring, and the energy-absorbing box 404 deforms, further absorbing the vehicle's kinetic energy, thereby preventing serious damage to the vehicle and ensuring safety during the testing process. Example

[0047] Please refer to Figures 1 to 4. Based on specific embodiments one to three, the folding plate 300 includes a first inclined plate 301 rotatably connected to the side of the mounting frame 103. A second inclined plate 302 is rotatably connected to the end of the first inclined plate 301 away from the mounting frame 103. A third inclined plate 303 is rotatably connected to the end of the second inclined plate 302 away from the mounting frame 103. A first hydraulic cylinder 304 is rotatably connected to the side of the mounting frame 103, and the output end of the first hydraulic cylinder 304 is rotatably connected to the side of the second inclined plate 302. A second hydraulic cylinder 305 and a third hydraulic cylinder 306 are rotatably connected to the sides of the first inclined plate 301 and the second inclined plate 302, respectively. The output ends of the second hydraulic cylinder 305 and the third hydraulic cylinder 306 are rotatably connected to the sides of the second inclined plate 302 and the third inclined plate 303, respectively. The slope can be reduced by unfolding the folding plate 300, making it more convenient for the vehicle to be tested to get on and off. The volume of the folding plate 300 can be reduced by folding it, making it more convenient to move.

[0048] Specifically, anti-slip strips are laid on the top of the top plate 104, the first inclined plate 301, the second inclined plate 302 and the third inclined plate 303.

[0049] The operation process of this embodiment is as follows: When it is necessary to unfold the folding plate, the first hydraulic cylinder 304 and the second hydraulic cylinder 305 are activated in sequence to push the first inclined plate 301 and the second inclined plate 302 to unfold respectively. Then, the third hydraulic cylinder 306 drives the third inclined plate 303 to complete the slope structure, thereby making it more convenient for the vehicle to be tested to go up and down. By reversing the above operation, the folding plate 300 can be folded, thereby making the movement of this utility model more convenient.
