[0029] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0030] First, see Figure 1 , Figure 1 2 is a schematic diagram of the structure of some embodiments of the vehicle-mounted lift in the folded state according to the present disclosure. Figure 1 As shown in FIG. 1 , the vehicle-mounted lift comprises a base 1, a support assembly 2, a connecting rod assembly 3 and a lift assembly 4. The base 1 can be mounted on the vehicle by connecting members such as bolts. Figure 1 As shown, it includes two base legs, or it can be an integral leg, and those skilled in the art can adjust it according to actual conditions.

[0031] The lower end of the connecting rod assembly 3 ( Figure 1 The base 1 is pivotally connected to the support assembly 3 (in the direction of the center axis) so that the connecting rod assembly 3 can rotate along the pivot axis. The base 1 and the connecting rod assembly 3 can be connected or hinged by a pin. As an example, the connecting rod assembly can include a connecting rod pivotally connected to the base and the support assembly and connecting the connecting rod and a jack or a cylinder. The jack or the cylinder can drive the connecting rod to rotate.

[0032] See next Figure 2 , Figure 2 1 is a schematic diagram of the structure of some embodiments of the vehicle-mounted lift in the first transition state according to the present disclosure. In some optional implementations of some embodiments, the connecting rod assembly 3 may include two connecting rod mechanisms (not shown as a whole in the figure) arranged horizontally and spaced apart. Since the two connecting rod mechanisms have the same structure, the following is the following ( Figure 2 The connecting rod mechanism with a direction (in the direction) is taken as an example. The two ends of the above-mentioned connecting rod mechanism connect the base 1 and the support assembly 2. Specifically, the above-mentioned connecting rod mechanism includes a first connecting rod 31, a second connecting rod 33 and a push-pull portion 32 which are vertically spaced apart. The two ends of the above-mentioned first connecting rod 31 and the above-mentioned second connecting rod 33 are pivotally connected to the above-mentioned base 1 and the above-mentioned support assembly 2. When the above-mentioned first connecting rod 31 and the second connecting rod 33 are rotated along the pivot axis with the base 1, the above-mentioned support assembly 2 can be lifted or lowered. The above-mentioned push-pull portion 32 is connected to the base 1 and the end of the above-mentioned second connecting rod 33 facing the support assembly 2. As Figure 2 In the first transition state shown in FIG. 1 , when the push-pull portion 32 is extended, the second connecting rod 33 and the first connecting rod 31 can be driven to rotate downward ( Figure 2 In the direction of the center), the support assembly 2 is downward ( Figure 2 When the push-pull portion 32 is retracted, the second link 33 and the first link 31 can be driven to rotate upward, so that the support assembly 2 moves upward until the support assembly 2 abuts against the vehicle load-bearing surface.

[0033] The push-pull part may include but is not limited to: a hydraulic cylinder, a pneumatic cylinder, an electric push rod, an electromagnetic push rod, etc.

[0034] It should be noted that the first connecting rod 31, the second connecting rod 33, the base 1 and the supporting assembly 2 can be pivotally connected by means of a pin or a hinge, and those skilled in the art can select and adjust according to actual conditions.

[0035] Optionally, the link mechanism may further include a connecting plate 34. The connecting plate 34 may be fixed to the supporting assembly 2. The connecting plate 34 is pivotally connected to the first connecting rod 31 and the second connecting rod 33 in a one-to-one correspondence.

[0036] See next Figure 3 And continue to read Figure 1 , Figure 3 2 is a schematic diagram of the structure of some embodiments of the second transition state of the vehicle-mounted lift according to the present disclosure. Figure 3 As shown, the support assembly 2 may include a support frame (not shown in the figure). The support frame is formed by connecting two longitudinal beams 21, 22, a top beam 23 and a bottom beam 24 end to end. Figure 3 The upper end of the above-mentioned longitudinal beams 21 and 22 is connected to the first connecting rod 31 and the second connecting rod 33 of the two connecting rod mechanisms in a one-to-one correspondence. The second ends of the above-mentioned two longitudinal beams 21 and 22 are connected to a fixing plate 29. The fixing plate 29 is used to engage with a contact surface. The above-mentioned contact surface can be the ground or the bearing surface of the vehicle. The right end ( Figure 3 The lifting machine assembly 4 is pivotally connected to the vehicle lifting machine assembly 4. An anti-skid pad or other friction-increasing material can be provided at the bottom of the fixing plate 29 to enhance the stability of the vehicle lifting machine.

[0037] Optionally, the support assembly 2 may further include a winch assembly (not indicated as a whole in the figure). The winch assembly is used to fix the lift assembly 4 when the vehicle-mounted lift is in a folded state. Specifically, the winch assembly includes a winch 25, a steel wire rope 26, a first fixed pulley 27 and a second fixed pulley 28. The winch 25 is mounted to the bottom end of the top beam 23. The first fixed pulley 27 is fixed to the side of the top beam 23 facing the lift assembly 4. The second fixed pulley 28 is arranged below the winch 25. A load-bearing connecting rod may be arranged below the winch 25, and the load-bearing connecting rod is fixedly connected to the two longitudinal beams 21 and 22. The second fixed pulley 28 is fixed to the load-bearing connecting rod. The steel wire rope 26 extends from the winch 25, passes through the second fixed pulley 28 and the first fixed pulley 27, and is detachably connected to the lift assembly 4. So that in the case of Figure 1 When the vehicle-mounted lift is in the folded state, the hoist assembly can fix the lift assembly 4 so that the lift assembly 4 remains in the folded state.

[0038] See also Figure 4 And continue to read Figure 3 , Figure 4 Schematic diagram of the structure of some embodiments of the vehicle lift in the open state according to the present disclosure. Figure 3 and Figure 4 As shown, the lift assembly 4 includes a bottom plate 42 and a lift body (not shown as a whole) disposed on the bottom plate 42. Figure 4 The left end shown in the figure) is pivotally connected to the fixed plate 29. The second end ( Figure 4 The right end shown in FIG. 2 is provided with a pull ring 46. In the folded state, the steel wire rope 26 is connected to the pull ring 46. With the help of the winch 25, the steel wire rope 26 is rolled up, so that the bottom plate 42 is vertically turned to the support assembly 2.

[0039] Optionally, the lift body may include two lifting mechanisms spaced apart. This can meet the lifting requirements for long wheelbase vehicles. The lifting mechanism includes a support plate 41 and a scissor lift portion pivotally connected to the support plate 41. The scissor lift portion is placed on the bottom plate 42. In a working state, the scissor lift portion drives the support plate 41 to rise, and then acts on the vehicle to be repaired. The scissor lift portion may include a first scissor portion 45 and a second scissor portion 44 cross-pivotally connected, and a hydraulic cylinder 43. The hydraulic cylinder 43 is connected to the bottom plate 42 and the second scissor portion 44. In a working state, the hydraulic cylinder 43 is extended and retracted, so that the second scissor portion 44 rotates along the pivot axis. Thereby raising or lowering the support plate 41.

[0040] The above technical solution, as an inventive point of an embodiment of the present disclosure, solves the new technical problem three "the vehicle-mounted lift with folding and opening functions is often structurally unstable". The factors that lead to the instability of the vehicle-mounted lift are often as follows: when the vehicle-mounted lift enters the open state from the folded state, due to its own variability function, it usually causes the vehicle-mounted lift to have poor stability and is prone to deformation again. If the above factors are solved, the effect of improving the stability of the vehicle-mounted lift can be achieved. In order to achieve this effect, the present disclosure introduces a connecting rod mechanism, a support frame and a fixed plate. When the vehicle-mounted lift is in the open state, the push-pull part of the connecting rod mechanism can be pushed out and continuously apply a force to the second connecting rod, so that the support frame and the fixed plate are subjected to a downward force, thereby increasing the pressure applied by the fixed plate to the ground, and then increasing the friction between the fixed plate and the ground. In this way, under the fixation of the base and the fixed plate, the stability of the vehicle-mounted lift can be improved.

[0041] Finally, combine Figures 1 to 4 The working principle of the vehicle-mounted lift is described. Figure 1 The vehicle lift is shown in the folded state. Figure 2 ) is contracted, and the first connecting rod 31 and the second connecting rod 33 drive the longitudinal beam 21 to a vertical state. At the same time, the wire rope 26 is connected to the pull ring 46, and the hoist 25 rolls up the wire rope 26, so that the lifting machine assembly 4 is folded. Figure 2 What is shown is the first transition state of the vehicle-mounted lift. When the push-pull portion 32 is extended, the first connecting rod 31 and the second connecting rod 33 rotate to the right, so that the longitudinal beam 21 moves to the lower right until the fixing plate 29 is tightly engaged with the ground. Figure 3 The second transition state of the vehicle-mounted lift is shown, when the winch 25 releases the wire rope 26, under the action of gravity, the lift assembly 4 gradually turns from the vertical direction to the horizontal direction until it engages with the ground. At this time, the wire rope 25 is removed. Figure 4This is the open state of the vehicle-mounted lift. The scissor lifter drives the support plate 41 to move upward, thereby completing the lifting of the vehicle to be repaired.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in the embodiments of the present disclosure (but not limited to) and the technical solutions formed.
