[0042] like Figures 1-12 As shown, a vehicle lift includes: a platform 100, a support arm system 200, a bracket system 300, an anti-slip device system 400, a locking system 500, and a pulley system 600. The lower part of the platform 100 is connected to the bracket system 300. One end of the support arm system 200 is connected to the platform 100. The other end of the support arm system 200 is provided with the locking system 500 and the pulley system 600. The lower part of the support arm system 200 is provided with the locking system 500 and the pulley system 600. The upper part of the support arm system 200 is provided with the anti-slip device system 400.
[0043] The locking system 500 includes a fixed locking element 510, a movable locking element 520, a pull rod 530, a handle 540, a preload spring 550, and a screw 560. The fixed locking element 510 is connected to one end of the support arm system 200 and to the movable locking element 520. The movable locking element 520 is located at the bottom end of the support arm system 200 and is connected to the pull rod 530 via the screw 560. One end of the pull rod 530 is connected to the support arm system 200 via the preload spring 550, and the other end of the pull rod 530 has a handle 540 connected to the other end of the support arm system 200. When an axial tension is applied to the handle 540, the movable locking element 520 moves from the locked position to the unlocked position; the return from the unlocked position to the locked position is achieved by the preload spring 550. The pull rod 530 and handle 540 form a single folding component, creating a curved section. This unique curved shape allows the user to place their feet under the handle when the upper platform is in a low position. The movable locking element 520 can be secured to the pull rod 530 by screws passing through elliptical guide holes formed in the wall, using four screws that engage with four channel holes formed in the lower wall 230 of the support arm system 200.
[0044] Platform 100 includes: an upper surface structure 110, longitudinal edges 120, and transverse edges 130. The upper surface structure 110 has longitudinal edges 120 on both sides and transverse edges 130 at both the front and rear ends. The upper surface structure 110 of the platform is designed to be flat and horizontal to support the vehicle.
[0045] The support arm system 200 includes: a free end 210, a joint end 220, a lower wall 230, an upper wall 240, a U-shaped support member 250, a free edge 260, a mechanical stop 270, and a latch 280. The lower wall 230 and the upper wall 240 are respectively provided with a free end 210 and a joint end 220 at their ends, and the lower wall 230 and the upper wall 240 are connected. The U-shaped support member 250 is located on the longitudinal edge 120 and is connected to the longitudinal edge 120 via the joint end 220. The free edge 260 and the mechanical stop 270 are located on the lower wall 230, and the latch 280 is located on the free end 210. This utility model includes four support arm systems 200, each support arm system 200 being rotatably mounted and fixed on a support frame on one of the longitudinal edges 120 of the platform. The support arm system 200 has a distinct horizontal Z-axis longitudinal direction and is rotatable about a vertical Y-axis passing through the U-shaped support 250, allowing rotation between a resting position where the support arm system 200 is folded along its longitudinal edge 120 and an operating position forming a non-zero angle with respect to that edge. The free end 210 of the support arm system 200 can be associated with a movable pulley system 600, in which pulley bodies 620 are connected to a wheel holder 610 adapted to slide along the free edge 260 of the support arm system 200. The wheel holder 610 of the pulley system 600 engages with a latch 280 located at the end of the support arm, which holds the wheel holder 610 in a lateral position once it slides to and contacts the mechanical stop 270.
[0046] The support system 300 is a scissor-type cross support, and the support system 300 is equipped with a hydraulic clamp 310. The scissor-type cross support specifically consists of two pairs of parallel scissors arranged in an "X" shape, which can move between a substantially horizontal low position and a substantially inclined high position. These two pairs of scissors are divided into an outer pair of scissors and an inner pair of scissors. The lower end of the outer scissors is placed on the ground and hinged to the upper end at the longitudinal edge of the upper platform. The lower end of the inner scissors is placed on the ground, and the upper end is placed under the platform.
[0047] The anti-slip device system 400 includes an anti-slip plate 410 and an anti-slip bracket 420. The anti-slip plate 410 is connected to the upper wall 240 and fixed to the anti-slip bracket 420, which is fixed to the support arm system 200. The anti-slip plate 410 is made of rubber and is used to contact the contact points under the chassis of the vehicle to be lifted. The number of anti-slip plates is equal to the number of corresponding support arm systems 200, and they are also distributed along each edge of the platform to promote a uniform weight distribution of the lifting vehicle on the lifting structure.
[0048] The outer edge of the fixed locking element 510 is provided with a first tooth 511, and the outer edge of the movable locking element 520 is provided with a second tooth 521. The number of second teeth 521 is less than the number of first teeth 511, and the interval angle α between the first teeth 511 is 8° to 12°. In this embodiment, the number of second teeth 521 is three. The angle α between the first teeth 511 and the second teeth 521 is 9° in this embodiment, and the tooth thickness is between 8 mm in this embodiment.
[0049] The pulley system 600 includes a wheel bracket 610 and a pulley body 620. The pulley body 620 is connected to the wheel bracket 610, and the wheel bracket 610 is connected to the support arm system 200.
[0050] The specific process of this utility model is as follows: The mobile lift is pushed to a suitable position under the vehicle, with the platform 100 at its lowest position, close to the ground. The handle 540 is pulled to separate the movable locking element 520 from the fixed locking element 510, then the support arm system 200 is unlocked, rotating it from its folded, stationary position to an operating position suitable for the vehicle chassis. The handle 540 is released, and the pre-tensioned spring 550 returns the movable locking element 520 to its locked position, locking the angle of the support arm system 200. In the next stage, the position of the anti-slip plate 410 on the support arm system 200 is adjusted to align with the contact point with the vehicle chassis. The hydraulic clamp 310 is activated, driving the support system 300, raising the platform 100 from its low position to the required height. The vehicle is stably supported, allowing for inspection, repair, or maintenance work. Finally, operate the hydraulic cable 310 to slowly lower the platform 100 to the ground, pull the handle 540 to unlock the support arm system 200, rotate the support arm system 200 back to the folded position, release the handle 540 to lock the support arm system 200, and move the elevator to the storage position.
[0051] The innovations of this utility model are as follows: It innovatively solves the industry problem of the support arm system 200 being unable to lock when unloaded; it adopts a mechanical locking method where the fixed locking element 510 and the movable locking element 520 interlock; locking / unlocking is achieved through a simple pull operation of the handle 540, making operation intuitive and convenient; the locking element adopts a detachable design, facilitating maintenance and replacement of worn parts. The movable design allows for lifting without being fixed to the ground; it avoids the safety hazards associated with traditional lifts requiring pit installation; the support arm system 200 can flexibly switch between a stationary position and an operating position; the optimized weight distribution design, with the four support arm systems 200 evenly distributed, ensures stability. Ultimately, it meets the requirements of the national standard GB27695-2011 for safety devices of car lifts; the locking mechanism of the support arm system 200 ensures that it remains locked even when unloaded; the pre-tensioned spring 550's automatic reset mechanism ensures that the locking device automatically returns to the locked position after the handle 540 is released; the design of the handle 540 allows for safer operation at lower positions.
[0052] Compared with traditional technology, this utility model can lock the support arm when there is no load on it; it achieves simple and fully mechanical locking / unlocking through handle operation; and it is designed to facilitate the replacement of potentially worn parts, with the fixed locking element and the movable locking element of the lock being easy to disassemble and replace.
[0053] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
