[0026] The description of the directions "upper" and "lower" in this utility model is as follows: Figure 1 The directions shown are for reference only and are used to explain the Figure 1 The relative positional relationship between the components in the shown posture. If the specific posture changes, the directional indication will also change accordingly.

[0027] When using a two-post lift to raise or lower a vehicle, the lifting arms on the two-post lift's columns typically do not directly contact the vehicle body. Instead, a support device is installed on the lift arm to provide support for the vehicle body. Existing support devices typically include a support rod and a support base. The support base is connected to the vehicle body, and the support rod is connected between the support base and the lifting arm. This structure has good vertical load-bearing stability but poor lateral load-bearing stability. When the vehicle body tilts, a large lateral force is applied to the support device, which is prone to lateral displacement and poor support stability.

[0028] The utility model proposes a vehicle body support device, which is used to support between a two-post lift and a vehicle body. The vehicle body support device includes a connecting sleeve 10, a support member 20 and a support block 30. The connecting sleeve 10 extends vertically, and the lower end of the connecting sleeve 10 is used to connect with the lifting arm of the two-post lift, and the upper end of the connecting sleeve 10 forms a socket interface 13; the support member 20 includes a connecting column 21 and a support seat 22, the connecting column 21 extends vertically, the lower end of the connecting column 21 extends into the connecting sleeve 10 and is socketed in the socket interface 13, the upper end of the connecting column 21 is supported on the bottom of the support seat 22, and the top edge of the support seat 22 extends upward and encloses a support slot 23; the bottom of the support block 30 is plugged into the support slot 23, and the top of the support block 30 is used to connect with the vehicle body.

[0029] See also Figure 1 The connecting sleeve 10 is connected to the lifting arm and extends vertically. The support member 20 is located between the connecting sleeve 10 and the support block 30. The lower end of the connecting column 21 extends into the socket 13 of the connecting sleeve 10. The upper end of the connecting column 21 is connected to the bottom of the support seat 22 to provide support for the support member 20 through the connecting sleeve 10. The bottom of the support block 30 is inserted into the support slot 23 to provide support for the support block 30 through the support member 20. The connecting sleeve 10 remains connected to the lifting arm, and the support block 30 remains connected to the vehicle body. When the two-post lift is lifting the vehicle body, it is only necessary to sleeve the support member 20 into the socket 13 of the connecting sleeve 10, adjust the position of the two-post lift horizontally, align the support slot 23 with the bottom of the support block 30, and then drive the lifting arm upward to make the bottom of the support block 30 engage with the support slot 23 to provide support for the vehicle body through the vehicle body support device; when stopping lifting, it is only necessary to drive the lifting arm downward to disengage the support block 30 from the support slot 23, and then the support block 30 can be separated from the support member 20.

[0030] The vehicle body support device proposed in the present invention connects a connecting sleeve 10 to the lifting arm of a two-post lift and a support block 30 to the vehicle body. The lower end of the connecting post 21 can be inserted into the socket 13 of the connecting sleeve 10, and the bottom of the support block 30 can be inserted into the support slot 23, so that the support member 20 can be quickly installed between the connecting sleeve 10 and the support block 30, facilitating quick installation and removal. When the two-post lift is used to lift the vehicle body multiple times, it can significantly reduce the installation time of the vehicle body support device and improve installation efficiency. In addition, the top edge of the support seat 22 extends upward to form the sidewalls of the support slot 23. When the support block 30 is inserted into the support slot 23, the sidewalls of the support slot 23 can provide lateral support for the support block 30, effectively improving the lateral stability of the vehicle body support device, preventing lateral displacement during the lifting of the vehicle body by the two-post lift, and ensuring that the vehicle body support device provides stable support for the vehicle body.

[0031] In one embodiment, the support block 30 includes a bottom plate 34, multiple side plates and multiple connecting plates 33. The multiple side plates are connected end to end along the outer edge of the bottom plate 34, and the bottom plate 34 and the multiple side plates are combined to form an escape space with an open space facing upward. Each connecting plate 33 is connected to the top of any side plate, and each connecting plate 33 is used to connect to the vehicle body.

[0032] See also Figure 2 The bottom plate 34 and multiple side plates together enclose an avoidance space. When the support block 30 is connected to the vehicle body through the connecting plate 33, the avoidance space can accommodate and avoid the protruding structure on the vehicle body, so that the support block 30 can remain connected to the vehicle body and avoid interfering with the vehicle body structure, ensuring that the support block 30 can adapt to the vehicle body structure of different models.

[0033] In one embodiment, the number of side panels is four, of which two oppositely arranged side panels are first side panels 31, and the other two oppositely arranged side panels are second side panels 32; the two ends of each first side panel 31 are respectively a first end and a second end, the two first ends extend in a direction approaching each other and are connected by a second side panel 32, and the two second ends extend in a direction approaching each other and are connected by another second side panel 32, and a connecting plate 33 is connected to the top of each first side panel 31.

[0034] Furthermore, the two first side panels 31 are arranged opposite to each other, and the first end of each first side panel 31 is bent toward the first end of the other first side panel 31, and the two first ends are respectively connected to the two ends of the second side panel 32; similarly, the second end of each first side panel 31 is bent toward the second end of the other first side panel 31, and the two second ends are respectively connected to the two ends of the other second side panel 32, so that the two first side panels 31 and the two second side panels 32 are connected end to end and enclosed to form a frame structure, thereby effectively improving the lateral support stability of the support block 30.

[0035] In one embodiment, each connecting plate 33 extends from the top of the first side plate 31 in a direction away from the other first side plate 31, and each connecting plate 33 is provided with a plurality of mounting holes 36, each mounting hole 36 is for a bolt 35 to pass through, so that the connecting plate 33 is connected to the vehicle body by the bolt 35.

[0036] See also Figure 2 Each connecting plate 33 is connected to the top of the first side plate 31 and extends toward the side away from the escape space, ensuring sufficient contact area between the connecting plates 33 and the vehicle body, ensuring a secure connection between the connecting plates 33 and the vehicle body while preventing the connecting plates 33 from obstructing the escape space. The connecting plates 33 are connected to the vehicle body via bolts 35, facilitating quick assembly and disassembly of the support block 30 and the vehicle body. The bolts 35 can be flexibly positioned to accommodate the varying body structures of different vehicle models, ensuring flexible installation and convenient connection.

[0037] In one embodiment, the connecting plate 33 extends horizontally, a rubber pad is laid on the top of the connecting plate 33 , and a through hole for the bolt 35 to pass through is opened at a position of the rubber pad corresponding to the mounting hole 36 .

[0038] Furthermore, the connecting plate 33 extends horizontally, allowing its upper surface to contact the vehicle body, providing support for the vehicle body. When the connecting plate 33 is supported by the vehicle body, the pressure from the vehicle body on the connecting plate 33 is more evenly distributed, preventing damage to the vehicle body caused by concentrated pressure. Furthermore, a rubber pad is placed between the vehicle body and the connecting plate 33. The rubber pad can be made of a highly elastic and wear-resistant rubber material, further reducing friction and vibration between the vehicle body and the connecting plate 33, providing further protection for the vehicle body and preventing damage from the connecting plate 33 during lifting and lowering.

[0039] In one embodiment, the connecting sleeve 10 includes a first support section 11 and a second support section 12 connected to the lower end of the first support section 11. The upper end of the first support section 11 forms a socket 13, and the inner cavity size of the first support section 11 is smaller than the size of the socket 13, so that a support step is formed between the inner cavity of the first support section 11 and the socket 13. The lower end of the connecting column 21 can extend into the socket 13 and be supported on the support step, and the lower end of the second support section 12 is used to connect to the lifting arm.

[0040] See also Figure 3 A socket 13 is formed in the upper end of the first support section 11, and an inner cavity is formed in the lower end of the first support section 11. The socket 13 of the first support section 11 and the inner cavity are interconnected, and the inner cavity of the first support section 11 and the inner cavity of the second support section 12 are interconnected. The inner diameter of the socket 13 is larger than the inner diameter of the inner cavity of the first support section 11, and the inner diameter of the lower end of the connecting column 21 is between the inner diameters of the socket 13 and the inner diameter of the inner cavity of the first support section 11, so that the lower end of the connecting column 21 can extend into the socket 13 and abut against the support step. While the support step provides support for the connecting column 21, the side wall of the socket 13 provides support for the side of the connecting column 21, effectively improving the lateral support stability of the connecting column 21, and conveniently assembling and disassembling the connecting column 21 and the connecting sleeve 10.

[0041] In one embodiment, the inner wall of the socket 13 is provided with an internal thread, and the outer wall of the connecting column 21 is provided with an external thread for matching with the internal thread.

[0042] Furthermore, the inner diameter of the socket 13 matches the outer diameter of the connecting column 21, and the connecting column 21 extends into the socket 13 and engages with the socket 13 thread, so that the connection between the connecting column 21 and the socket 13 is firm and easy to load and unload. The height of the vehicle body can be fine-tuned by adjusting the connection length between the connecting column 21 and the socket 13, thereby keeping the vehicle body level during the vehicle lifting process.

[0043] In one embodiment, a limiting protrusion 14 is provided on the outer sleeve of the connecting sleeve 10. The limiting protrusion 14 is located at the connection between the first support section 11 and the second support section 12. The lifting arm can be mounted outside the second support section 12 and abut against the limiting protrusion 14.

[0044] Furthermore, the outer wall of the connecting sleeve 10 protrudes outward to form a limiting convex ring 14, and the second supporting section 12 can extend into the socket of the lifting arm, so that the lifting arm abuts against the bottom of the limiting convex ring 14, so that the lifting arm and the connecting sleeve 10 are firmly connected, avoiding displacement of the lifting arm and the body support device during the vehicle lifting process, and improving the support stability of the body support device.

[0045] In one embodiment, the first support section 11, the second support section 12 and the limiting protruding ring 14 are integrally formed. The connecting sleeve 10 has high structural strength and pressure bearing capacity, and can provide stable support for the support member 20 and the support block 30 thereon.

[0046] This utility model also provides a vehicle lifting device comprising a two-post lift and a vehicle body support device. The specific structure of the vehicle body support device is similar to that of the aforementioned embodiments. Since this vehicle lifting device utilizes all of the technical solutions of all of the aforementioned embodiments, it possesses at least all of the beneficial effects provided by the technical solutions of the aforementioned embodiments, and therefore, a detailed description thereof will not be repeated here. The vehicle body support device is supported between the two-post lift and the vehicle body.

[0047] It can be understood that the top edge of the support seat 22 extends upward to form the side wall of the support slot 23. When the support block 30 is plugged into the support slot 23, the side wall of the support slot 23 can provide lateral support to the support block 30, effectively improving the lateral stability of the vehicle body support device, avoiding lateral displacement during the lifting of the vehicle body by the two-post lift, and realizing that the vehicle body support device provides stable support for the vehicle body.
