Description

Technical Field

[0001] This invention relates to the field of maintenance platform technology, and in particular to a new energy vehicle maintenance platform. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source and integrate advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles, new technologies, and new structures. When a new energy vehicle malfunctions, it needs to be sent to a corresponding repair platform for repair. This platform can lock all four wheels of the vehicle to prevent instability during maintenance and can also raise the vehicle to facilitate inspection of the chassis. This avoids the difficulty in manually controlling the height of the vehicle due to its large size and weight. Thus, the convenience of maintenance and routine upkeep of new energy vehicles is greatly improved through the cooperation of the repair platform.

[0003] The prior art, Chinese invention patent application number CN201811639479.8, discloses a lifting platform for repairing new energy vehicles, which can lift and fix the vehicle, improving safety. However, in the actual operation, when the positioning block moves to the rear of the vehicle's rear wheel, it is necessary to control the vehicle to move back so that the rear wheel abuts against the positioning block, and then control the clamping block to abut against the front wheel. The operation of the positioning and clamping mechanisms is relatively cumbersome, increasing the workload of the staff and affecting the efficiency of vehicle repair. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art and to propose a new energy vehicle maintenance platform.

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

[0006] A new energy vehicle maintenance platform includes a base, a bracket on the base, a hydraulic cylinder fixed on the bracket, a side plate connected to the piston rod of the hydraulic cylinder, a lifting seat connected to the side plate, and two wheel seats connected by a connecting plate. Each wheel seat has a wheel groove, a limit seat is provided at the upper end of the wheel groove, a force-relieving buffer assembly is provided on the limit seat, a self-positioning limiting assembly is provided at the front end of each wheel seat, and a transmission component is provided between the self-positioning limiting assembly and the force-relieving buffer assembly.

[0007] Preferably, the force-relieving buffer assembly includes a sliding plate slidably connected to the limiting seat, an arc-shaped plate disposed at the end of the sliding plate, an ear plate disposed at the end of the sliding plate away from the arc-shaped plate, and a first elastic telescopic rod disposed between the ear plate and the limiting seat.

[0008] Preferably, the transmission component includes a support plate fixed on the limiting seat, a rotating rod rotatably connected to the support plate, a drum and a driven gear disposed on the rotating rod, and a pull rope wound and connected to the drum. The end of the pull rope away from the drum is connected to the self-positioning limiting component, and a rack plate meshing with the driven gear is disposed on the slide plate.

[0009] Preferably, the self-positioning limiting component includes a fixed seat fixed to the bottom side of the wheel seat, a rotating rod rotatably connected to the fixed seat, a limiting plate disposed on the rotating rod, a sliding block slidably connected to the fixed seat, and a support plate movably connected to the sliding block and the limiting plate. A slider is fixedly disposed at the bottom of the sliding block, and a groove for sliding of the slider is provided on the fixed seat. An elastic element is disposed between the inner wall of the groove and the slider, and a movable groove for the movement of the limiting plate is provided in the wheel groove.

[0010] Preferably, a guide is fixed at the bottom of the wheel seat, and the end of the pull rope away from the drum passes through the guide and is connected to the slide.

[0011] Preferably, the self-positioning limiting component further includes an elastic telescopic rod disposed in the slide, the fixed base having equally spaced insertion holes along its length, the elastic telescopic rod being inserted into the insertion holes, and the end of the elastic telescopic rod having a pressing bevel.

[0012] Preferably, multiple elastic telescopic rods are provided, and the multiple elastic telescopic rods are arranged at unequal intervals within the slide block.

[0013] Preferably, a top rod is fixed to the top of the base, and the top rod is inserted into the insertion hole and moves against the elastic telescopic insertion rod.

[0014] Preferably, the bottom wall of the wheel groove is inclined, and the lower end of the bottom wall of the wheel groove is located below the limiting seat.

[0015] Preferably, the front end of the base is provided with an inclined guide block, which is fixed to the ground.

[0016] Compared with the prior art, the present invention provides a new energy vehicle maintenance platform, which has the following beneficial effects:

[0017] 1. This new energy vehicle repair platform activates the stress-relief buffer component by moving the car wheels within the wheel grooves. When the stress-relief buffer component is in operation, it drives the self-positioning limiting component through the transmission component, thereby automatically limiting the car wheels and preventing the car from shaking during repair. It is simple to operate and effectively improves the efficiency of car repair.

[0018] 2. This new energy vehicle repair platform, after the vehicle repair is completed, lowers the wheel seat using a hydraulic cylinder, causing the wheel seat to abut against the base, automatically releasing the self-positioning limiting component from restricting the rear wheels of the vehicle. No other operation is required from the staff, reducing their workload and further improving the efficiency of vehicle repair.

[0019] 3. In this new energy vehicle repair platform, when the sliding block uses the support plate to abut against the limiting plate, the limiting plate abuts against the wheel. Multiple elastic telescopic rods with unequal spacing are set at the bottom of the sliding block, which makes it easy to move the sliding block to any position of the fixed seat. At least one elastic telescopic rod is aligned with the insertion hole to ensure that the limiting plate and the wheel are tightly abutted, effectively preventing the car from loosening during repair.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] Example: Refer to Figure 1-7 A new energy vehicle maintenance platform includes a base 1, a support 2 on the base 1, a hydraulic cylinder 201 fixed on the support 2, a side plate 202 connected to the piston rod of the hydraulic cylinder 201, a lifting seat 3 connected to the side plate 202, and two wheel seats 302 connected by a connecting plate 301. The wheel seats 302 have wheel grooves 3021, a limit seat 4 is provided on the upper side of the end of the wheel groove 3021, a force relief buffer assembly is provided on the limit seat 4, a self-positioning limiting assembly is provided at the front end of the wheel seat 302, and a transmission component is provided between the self-positioning limiting assembly and the force relief buffer assembly.

[0032] Furthermore, the force-relieving buffer assembly includes a slide plate 401 slidably connected to the limiting seat 4, an arc plate 402 disposed at the end of the slide plate 401, an ear plate 403 disposed at the end of the slide plate 401 away from the arc plate 402, and a first elastic telescopic rod 404 disposed between the ear plate 403 and the limiting seat 4.

[0033] Furthermore, the transmission components include a support plate 5 fixed on the limiting seat 4, a rotating rod 501 rotatably connected to the support plate 5, a drum 502 and a driven gear 503 provided on the rotating rod 501, and a pull rope 504 wound and connected to the drum 502. One end of the pull rope 504 away from the drum 502 is connected to the self-positioning limiting component. A rack plate 4011 that meshes with the driven gear 503 is provided on the slide plate 401.

[0034] Furthermore, the self-positioning limiting component includes a fixed base 6 fixed to the bottom side of the wheel seat 302, a rotating rod 601 rotatably connected to the fixed base 6, a limiting plate 602 provided on the rotating rod 601, a sliding block 7 slidably connected to the fixed base 6, and a support plate 701 movably connected to the sliding block 7 and the limiting plate 602. The bottom of the sliding block 7 is fixed with a slider 702. The fixed base 6 is provided with a groove 603 for the slider 702 to slide. An elastic element 6031 is provided between the inner wall of the groove 603 and the slider 702. The wheel groove 3021 is provided with a movable groove 8 for the limiting plate 602 to move.

[0035] Furthermore, a guide 9 is fixedly provided at the bottom of the wheel seat 302, and the end of the pull rope 504 away from the drum 502 passes through the guide 9 and is connected to the slide 7.

[0036] Furthermore, the self-positioning limiting component also includes an elastic telescopic rod 703 disposed in the slide 7. The fixed base 6 has equally spaced insertion holes 10 along its length direction. The elastic telescopic rod 703 is inserted into the insertion holes 10. The end of the elastic telescopic rod 703 has a pressing slope.

[0037] Furthermore, a top rod 11 is fixedly provided on the top of the base 1. The top rod 11 is inserted into the insertion hole 10 and moves against the elastic telescopic insertion rod 703.

[0038] Furthermore, the bottom wall of the wheel groove 3021 is inclined, and the lower end of the bottom wall of the wheel groove 3021 is placed under the limit seat 4.

[0039] Furthermore, an inclined guide block 12 is provided at the front end of the base 1, and the inclined guide block 12 is fixed to the ground.

[0040] Specifically, the car enters the wheel seat 302 via the inclined guide block 12. The wheel moves along the wheel groove 3021 of the wheel seat 302 until the car wheel abuts against the arc plate 402. The arc plate 402 is forced to move the slide plate 401 towards the limit seat 4. During this period, the rack plate 4011 on the slide plate 401 meshes with the driven gear 503. The driven gear 503 drives the drum 502 to rotate via the rotating rod 501. The drum 502 releases the pull rope 504, so that the pull rope 504 no longer applies pressure to the slide seat 7. When tension is applied, the slide block 7 returns to its original position under the pull of the stretched elastic element 6031. The slide block 7 moves towards the rotating rod 601, and the slide block 7 pushes the limiting plate 602 upward through the support plate 701, so that the limiting plate 602 abuts against the wheel of the car located at the front end of the wheel groove 3021. At this time, the elastic telescopic rod 703 on the slide block 7 aligns with one of the insertion holes 10 on the fixed seat 6. Then, by controlling the operation of the hydraulic cylinder 201, the piston rod of the hydraulic cylinder 201 drives the wheel seat 302 upward. When the slide 7 moves upward, it separates from the base 1, causing the top rod 11 to move out of the insertion hole 10. The elastic telescopic rod 703 automatically inserts into the insertion hole 10, restricting the position of the slide 7, thereby maintaining the limiting plate 602 in contact with the wheel. This ensures that the wheels at both ends of the car abut against the arc plate 402 and the limiting plate 602, respectively. It should be noted that because the inner wall of the bottom of the wheel groove 3021 is inclined, the car will not move towards the front end of the wheel groove 3021 when it moves upward with the lifting seat 3, thus ensuring the position of the limiting plate 602. 2. The wheel is in contact with the wheel. After the car is repaired, the wheel seat 302 is lowered by the hydraulic cylinder 201, so that the wheel seat 302 abuts against the base 1. The push rod 11 is inserted into the insertion hole 10, so that the elastic telescopic insertion rod 703 retracts. The position of the slide 7 is no longer restricted. The car can move directly along the wheel groove 3021 and press down the limiting plate 602 to move out. The self-positioning limiting component automatically releases the restriction on the rear wheel of the car. No other operation is required from the staff, which reduces the workload of the staff and improves the efficiency of car repair.

[0041] Reference Figure 4 and Figure 6 As a preferred technical solution of the present invention, furthermore, multiple elastic telescopic rods 703 are provided, and the multiple elastic telescopic rods 703 are arranged at unequal intervals in the slide block 7; specifically, when the slide block 7 abuts against the limiting plate 602 using the support plate 701, the limiting plate 602 abuts against the wheel. Multiple elastic telescopic rods 703 at unequal intervals are provided at the bottom of the slide block 7, so that the slide block 7 can be moved to any position of the fixed seat 6. At least one elastic telescopic rod 703 is aligned and inserted into the insertion hole 10 to ensure that the limiting plate 602 is in a tight abutment state against the wheel, effectively preventing the car from loosening during maintenance.

[0042] 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.
