Referring first to fig. 1, fig. 1 is a schematic structural view of some embodiments of a folded state of an on-board lift according to the present disclosure. As shown in fig. 1, the vehicle-mounted lifter includes a base 1, a support assembly 2, a link assembly 3, and a lifter assembly 4. The base 1 may be mounted to the vehicle by a connecting member such as a bolt. The base 1 may include two base legs as shown in fig. 1, or may be an integral leg, and those skilled in the art may adjust the base according to actual situations.

The lower end (in the direction of fig. 1) of the above-mentioned link assembly 3 is pivotally connected to the base 1 such that the link assembly 3 can rotate along the pivot axis. The base 1 and the connecting rod assembly 3 may be connected or hinged by a pin. By way of example, the linkage assembly may include a link pivotally connected to the base and the support assembly and a jack or cylinder connecting the link to the jack or cylinder. The jack or the oil cylinder can drive the connecting rod to rotate.

Referring next to fig. 2, fig. 2 is a schematic diagram of some embodiments of a first transition state of an on-board lift according to the present disclosure. In some alternative implementations of some embodiments, the connecting rod assembly 3 may include two horizontally spaced link mechanisms (not shown in their entirety). Since the two link mechanisms have the same structure, the link mechanism on the lower side (direction in fig. 2) will be described as an example. The two ends of the link mechanism are connected with the base 1 and the supporting component 2. Specifically, the link mechanism includes a first link 31, a second link 33, and a push-pull portion 32 that are vertically spaced apart. Both ends of the first link 31 and the second link 33 are pivotally connected to the base 1 and the support assembly 2. When the first link 31 and the second link 33 are rotated along the pivot axis with the base 1, the support assembly 2 can be lifted up or down. The push-pull portion 32 is connected to the base 1 and one end of the second link 33 facing the support unit 2. In the first transition state shown in fig. 2, when the push-pull portion 32 is extended, the second link 33 and the first link 31 can be driven to rotate downward (in the direction of fig. 2), and the support assembly 2 moves downward (in the direction of fig. 2) until the support assembly 2 is engaged with the ground. When the push-pull portion 32 retracts, the second link 33 and the first link 31 can be driven to rotate upwards, so that the support assembly 2 moves upwards until the support assembly 2 abuts against the vehicle bearing surface.

The push-pull portion may include, but is not limited to: hydraulic cylinder, electric push rod, electromagnetic push rod, etc.

It should be noted that the first link 31 and the second link 33 can be pivotally connected to the base 1 and the support assembly 2 by a pin or a hinge, and those skilled in the art can select and adjust the connection according to actual situations.

Optionally, the linkage mechanism may further include a connecting plate 34. The connecting plate 34 may be fixedly attached to the support member 2. The above-described connecting plates 34 are pivotally connected to the first links 31 and the second links 33 in one-to-one correspondence.

Referring next to fig. 3 with continued reference to fig. 1, fig. 3 is a schematic diagram of some embodiments of a second transition state of a vehicle lift according to the present disclosure. As shown in fig. 3, the support assembly 2 may include a support frame (not shown in its entirety). The support frame is enclosed by two

longitudinal beams

21, 22, a top beam 23 and a bottom beam 24 connected end to end. First ends (upper ends shown in fig. 3) of the two

side members

21, 22 are connected to the first links 31 and the second links 33 of the two link mechanisms in a one-to-one correspondence. The second ends of the two

longitudinal beams

21 and 22 are connected to a fixing plate 29. The fixing plate 29 is intended to engage the contact surface. The contact surface may be the ground or the bearing surface of the vehicle. The right end (in the direction of fig. 3) of the fixed plate 29 is pivotally connected to the lifter assembly 4. Non-slip pads or other friction enhancing materials may be provided on the bottom of the fixed plate 29 to enhance the stability of the truck mounted lift.

Optionally, the support assembly 2 may further comprise a hoisting assembly (not shown in its entirety). The winding assembly is used for fixing the lifting machine assembly 4 when the vehicle-mounted lifting machine is in a folded state. Specifically, the hoisting assembly includes a hoisting machine 25, a wire rope 26, a first fixed sheave 27, and a second fixed sheave 28. The hoist 25 is mounted to the bottom end of the top beam 23. A first fixed sheave 27 is fixedly attached to the side of the top beam 23 facing the elevator assembly 4. The second fixed sheave 28 is provided below the hoist 25. A carrying connecting rod can be arranged below the hoisting machine 25, which carrying connecting rod is fixedly connected to the two

longitudinal beams

21, 22. The second fixed pulley 28 is fixedly attached to the load bearing link. The wire rope 26 extends from the hoist 25 and is detachably connected to the elevator assembly 4 through the second fixed sheave 28 and the first fixed sheave 27. So that the winding assembly can fix the lifting assembly 4 when the vehicle-mounted lifting machine shown in fig. 1 is folded, so that the lifting assembly 4 is kept folded.

Referring finally to fig. 4 with continued reference to fig. 3, fig. 4 is a schematic diagram of some embodiments of an open state of a vehicle lift according to the present disclosure. As shown in fig. 3 and 4, the lifter assembly 4 includes a base plate 42 and a lifter body (not shown in its entirety) provided to the base plate 42. The first end (left end as viewed in fig. 4) of the base plate 42 is pivotally connected to the fixed plate 29. A second end (right end in fig. 4) of the base plate 42 is provided with a pull ring 46. In the folded condition, the cable 26 is connected to the pull ring 46. Under the assistance of the winch 25, the wire rope 26 is wound up, so that the base plate 42 is vertically turned to the support assembly 2.

Alternatively, the lifter body may include two lifting mechanisms spaced apart from each other. Therefore, the lifting requirement of the vehicle with the long wheelbase can be met. The lifting mechanism includes a support plate 41 and a scissors lift pivotally connected to the support plate 41. The scissor lift is placed on the base plate 42. In the working state, the scissor lift portion drives the support plate 41 to rise, and then acts on the vehicle to be repaired. The scissors lifter may include first and

second scissors portions

45 and 44 that are cross-pivotally connected, and a hydraulic cylinder 43. The hydraulic cylinder 43 is connected to the base plate 42 and the second scissor portion 44. In the operating state, the hydraulic cylinder 43 extends and contracts, so that the second scissor portion 44 rotates along the pivot shaft. Thereby raising or lowering the support plate 41.

The technical scheme is used as an invention point of the embodiment of the disclosure, and solves the new technical problem that the structure of the vehicle-mounted lifter with the folding and opening functions is unstable. Factors that cause structural instability of the vehicle-mounted lifter are as follows: when the on-vehicle machine of lifting enters into the open mode by fold condition, because the variability function that self possesses can lead to this on-vehicle machine of lifting stability cross usually, take place deformation once more easily. If the above-mentioned factors have been solved, just can reach the effect that improves on-vehicle machine stability of lifting. To achieve this effect, the present disclosure introduces a linkage mechanism, a support frame, and a fixed plate. When the vehicle-mounted lifter is in an open state, the push-pull part of the link mechanism can be ejected out, and acting force is continuously applied to the second link, so that the support frame and the fixed plate are subjected to downward acting force, the pressure applied to the ground by the fixed plate is increased, and the friction force between the fixed plate and the ground is further improved. Therefore, the stability of the vehicle-mounted lifting machine can be improved under the fixation of the base and the fixing plate.

Finally, the operation principle of the vehicle-mounted lifting machine will be described with reference to fig. 1 to 4. Fig. 1 shows the vehicle-mounted lift in a folded state. At this time, the push-pull portion 32 (indicated in fig. 2) is contracted, and the first link 31 and the second link 33 bring the side member 21 to the vertical state. At the same time, the wire rope 26 is connected to the pull ring 46, and the hoist 25 winds up the wire rope 26, so that the hoist assembly 4 is folded. Fig. 2 shows a first transitional state of the vehicle lift. When the push-pull portion 32 is extended, the first link 31 and the second link 33 are rotated to the right, so that the longitudinal beam 21 is moved downward and rightward until the fixing plate 29 is closely engaged with the ground. Figure 3 shows the vehicle lift in a second transitional state in which the hoist assembly 4 is gradually turned from vertical to horizontal by gravity as the winch 25 pays out the cable 26 until it engages the ground. At this point the cable 25 is removed. Fig. 4 shows an open state of the vehicle-mounted lift. The scissor lifting part drives the support plate 41 to move upwards, and then the vehicle to be maintained is lifted.
