[0037] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 5 The support structure 2 according to the embodiment of the present utility model is described. The support structure 2 includes: a rotating assembly 10 and a support assembly 20 .

[0038] Specifically, if Figure 1-Figure 4 As shown, the support assembly 20 includes a first support portion 211 and a second support portion 212 , and the support assembly 20 is convertible between the first support portion 211 and the second support portion 212 .

[0039] In this embodiment, the support structure 2 is used to support the vehicle body so as to lift the vehicle body for transportation and installation. The support assembly 20 is provided with a first support portion 211 and a second support portion 212. The support assembly 20 is connected to the rotating assembly 10 and can rotate relative to the rotating assembly 10. The first support portion 211 and the second support portion 212 are both used to form support and positioning for the vehicle body. When the first support portion 211 is suitable for positioning with the vehicle body, the second support portion 212 is located away from the vehicle body. When the model of the vehicle body is changed, the second support portion 212 stops with the vehicle body to realize lifting the vehicle body. At this time, the first support portion 211 is located away from the vehicle body.

[0040] According to the support structure 2 of the embodiment of the utility model, a support assembly 20 that can be converted between a first support portion 211 and a second support portion 212 is provided to achieve the lifting, support and positioning of different vehicle bodies, so that the support structure 2 is suitable for the co-production of multiple vehicle models, has good compatibility, and can effectively reduce production costs.

[0041] In some embodiments, Figure 2 and Figure 3 As shown, the support assembly 20 includes: a first support member 21 and a second support member 22. The first support member 21 includes a first support portion 211 and a second support portion 212. The first support portion 211 and the second support portion 212 are respectively arranged at both ends of the first support member 21; the first support member 21 is connected to the second support member 22, and the second support member 22 is arranged between the first support member 21 and the rotating assembly 10. That is, the first support member 21 and the second support member 22 are stacked in the height direction and are detachably connected by bolts, screws, etc. The first support member 21 is formed with the first support portion 211 and the second support portion 212, that is, when the support assembly 20 contacts the vehicle body, the vehicle body is lifted by contacting the vehicle body through the side of the first support member 21 away from the second support member 22.

[0042] The first support member 21 is polyurethane, which has good stability, chemical resistance, resilience and mechanical properties, and has smaller compression deformation, so that the first support member 21 can better support the vehicle body when supporting the vehicle body, prevent the vehicle body from falling off the support assembly 20, and protect the vehicle body from being damaged by collision. The second support member 22 is a metal member, which can improve the structural strength of the support assembly 20, so as to better support the first support member 21.

[0043] In some embodiments, Figure 3As shown, a matching protrusion and a matching groove are provided on the side of the first support member 21 away from the second support member 22, and the matching protrusion and the matching groove are arranged along the length direction of the support assembly 20, and the matching protrusion is formed as the first support portion 211, and the matching groove is formed as the second support portion 212. That is, a matching protrusion and a matching groove are formed at the same time on the side of the first support member 21 away from the second support member 22, wherein the matching protrusion is formed as the first support portion 211, and the matching groove is formed as the second matching portion, and when the first matching portion matches with the vehicle body, the matching protrusion stops against the vehicle body, and when the second matching portion matches with the vehicle body, the matching groove stops against the vehicle body. That is, the support assembly 20 can selectively allow one of the matching protrusion and the matching groove to stop against the vehicle body of the vehicle model according to the needs and different vehicle models produced.

[0044] Therefore, the first support portion 211 is formed as a matching protrusion, and the second support portion 212 is formed as a matching groove, which can avoid the first support portion 211 and the second support portion 212 from interfering with each other when contacting and stopping with different vehicle bodies, ensure that the first support portion 211 and the second support portion 212 can limit the vehicle body, ensure the stability of the vehicle body during transportation, and increase safety.

[0045] In some embodiments, Figure 3 As shown, the support assembly 20 further includes: a positioning column 23, which is arranged on the second support member 22, and the positioning column 23 is arranged adjacent to the first support portion 211, and the positioning column 23 is detachably connected to the second support member 22. The positioning column 23 and the second support member 22 are threadedly matched to realize the connection between the positioning column 23 and the second support member 22, and the positioning column 23 exceeds the first support member 21 and is away from the side surface of the second support member 22 along the height direction of the support assembly 20, and the positioning column 23 cooperates with the first support portion 211, and the first support portion 211 is stopped against the vehicle body, and the positioning column 23 cooperates with the corresponding position of the corresponding vehicle body to realize positioning, for example, a positioning hole is formed at the bottom of the vehicle body, and the positioning column 23 needs to cooperate with the positioning hole when the first support portion 211 is stopped against the vehicle body, and the first support portion 211 is stopped against the vehicle body, so as to avoid the vehicle body from falling during transportation or lifting, thereby increasing the protection of the vehicle body and the reliability of the support assembly 20. The detachable connection between the positioning column 23 and the first support member 21 and the second support member 22 can facilitate replacement due to wear and tear, thereby reducing the use cost of the support assembly 20.

[0046] In some embodiments, Figure 3 As shown, the first support member 21 is formed with an avoidance groove 213, and the avoidance groove 213 is arranged on a side of the first support member 21 adjacent to the second support member 22. The avoidance groove 213 is arranged on a side of the first support member 21 facing the second support member 22, and the avoidance groove 213 and the matching protrusion are at least partially opposite along the height direction of the support assembly 20, so as to reasonably simplify the structure of the first support member 21 and increase the utilization of the structural space of the first support member 21.

[0047] In some embodiments, Figure 3 As shown, the second support member 22 is formed with a first through hole 221, and the first through hole 221 is opposite to the avoidance groove 213 along the height direction of the support assembly 20; the support assembly 20 also includes a sleeve 222, and one end of the sleeve 222 is matched with the first through hole 221. It can be understood that the first through hole 221 is provided on the second support member 22 and passes through the second support member 22 along the height direction of the support assembly 20, one end of the sleeve 222 is matched at the first through hole 221, and the other end of the sleeve 222 extends in a direction away from the first support member 21. The sleeve 222 is welded to the first support member 21.

[0048] Optionally, combined Figure 4 The rotating assembly 10 includes: a fixed plate 11, a mounting column 12, and a first connecting member 13. One end of the mounting column 12 is connected to the fixed plate 11, and the other end of the mounting column 12 extends toward the supporting assembly 20 along the height direction of the supporting structure 2. The mounting column 12 is formed with a mounting hole, and the mounting hole penetrates the mounting column 12 along the height direction of the supporting structure 2. The first connecting member 13 passes through the mounting hole to be connected with the supporting assembly 20. That is, one end of the first connecting member 13 passes through the first through hole 221 and the mounting hole from the end of the first through hole 221 adjacent to the first supporting member 21 to realize the connection between the rotating assembly 10 and the supporting assembly 20. The avoidance groove 213 provided on the first supporting member 21 is used to avoid the first connecting member 13, so as to facilitate the assembly of the first connecting member 13 with the supporting assembly 20. The first connecting member 13 is rotatable relative to the fixed plate 11, so that the supporting assembly 20 and the first connecting member 13 are rotatable relative to the fixed plate 11. After the first connecting member 13 is connected to the first through hole 221 , the first connecting member 13 and the second supporting member 22 are fixed by fasteners such as bolts.

[0049] In some embodiments, Figure 4 As shown, the first connecting member 13 includes: a head 131 and a rod 132. The head 131 abuts against a side of the second supporting member 22 adjacent to the first supporting member 21, and the head 131 is connected to the second supporting member 22; one end of the rod 132 is connected to the head 131, and the other end of the rod 132 passes through the second supporting member 22 and the fixing plate 11 to cooperate with the mounting hole. The cross-sectional area of ​​the head 131 is larger than the cross-sectional area of ​​the rod 132, which facilitates the first connecting member 13 to cooperate with the first through hole 221, facilitates the fixed connection between the head 131 and the second supporting member 22, increases the position limit of the installation of the first connecting member 13, and can effectively prevent the first connecting member 13 from falling off from the first through hole 221, thereby ensuring the effectiveness of the connection between the rotating assembly 10 and the supporting assembly 20.

[0050] In some embodiments, Figure 4As shown, the rotating assembly 10 further includes: a bearing 14 and a pad 15. The bearing 14 is sleeved on the mounting column 12 and can rotate around the mounting column 12. The pad 15 is sleeved on the mounting column 12 and is arranged between the bearing 14 and the second support member 22. That is, during the assembly process of the bearing 14 and the pad 15, the bearing 14 is sleeved on the mounting column 12 and then the pad 15 is sleeved. Here, the pad 15 is a columnar structure. The bearing 14 is sleeved on the mounting column 12 and can rotate relative to the mounting column 12. When the first connecting member 13 is installed, the sleeve 222 of the second support member 22 is opposite to the mounting column 12 on the fixed plate 11, and the end of the sleeve 222 away from the first support member 21 is sleeved on the outer peripheral side of the bearing 14 to achieve fixation with the bearing 14. The bearing 14 is used to realize the rotation of the support assembly 20 relative to the fixed plate 11, thereby reducing the friction during the rotation process, so that the rotation is smoother, that is, the conversion between the first support portion 211 and the second support portion 212 is smoother. The cushion block is provided to make the support assembly 20 and the rotating assembly 10 more tightly assembled, so as to prevent the support structure 2 from shaking and affecting the support effect.

[0051] Furthermore, the rotating assembly 10 also includes: a limit plate 16, which is arranged on a side of the fixed plate 11 away from the second support member 22, and the limit plate 16 is detachably connected to an end of the first connecting member 13 away from the first supporting member 21. That is, after the first connecting member 13 is penetrated with the first through hole 221 and the mounting hole, it is connected to the limit plate 16, and when the supporting assembly 20 rotates, the limit plate 16 rotates accordingly. When the limit plate 16 is connected to the first connecting member 13, the limit plate 16 stops against the fixed plate 11. Therefore, the setting of the limit plate 16 facilitates the connection with the first connecting member 13, so as to realize the connection between the supporting assembly 20 and the rotating assembly 10 in the height direction of the supporting structure 2.

[0052] In some embodiments, in combination Figure 4 The support structure 2 also includes: at least one limit assembly 30, the limit assembly 30 is arranged between the rotating assembly 10 and the supporting assembly 20, and the limit assembly 30 includes: a bushing 31, a second connecting member 32, and an elastic member 33. The bushing 31 is arranged on a side of the fixed plate 11 adjacent to the second supporting member 22; the second connecting member 32 passes through the fixed plate 11 and is connected to the bushing 31; the elastic member 33 is arranged in the bushing 31, one end of the elastic member 33 stops at the bushing 31, and the other end of the elastic member 33 stops at one end of the second connecting member 32 away from the bushing 31.

[0053] In this embodiment, the fixing plate 11 is provided with a second through hole 111, and the second connecting member 32 is provided with a second through hole 111 from the side of the fixing plate 11 away from the second support member 22 to cooperate with the bushing 31 provided on the other side of the fixing plate 11. The fastener is provided with the bushing 31 from the axial direction of the second connecting member 32 and is fixedly connected with the second connecting member 32. The fastener has a limiting function to prevent the second connecting member 32 from slipping out of the second through hole 111. The elastic member 33 is sleeved on the second connecting member 32 and one end of the elastic member 33 is stopped against the bushing 31, and the other end is stopped against the second connecting member 32, so that the second connecting member 32 can move along the height direction of the supporting structure 2. For example, the second connecting member 32 can move toward the bushing 31 under the action of an external force, and when the external force is removed, the second connecting member 32 moves in a direction away from the bushing 31 under the action of the elastic member 33. The elastic member 33 can be a spring. Therefore, by setting the limiting assembly 30 , the support assembly 20 can be fixed at a corresponding position after the rod is rotated relative to the fixing plate 11 , so that the support structure 2 remains in the current position, which facilitates the locking of the support assembly 20 .

[0054] In some embodiments, Figure 4 As shown, the limiting plate 16 is formed with at least one limiting groove 163, and the end of the second connecting member 32 away from the bushing 31 can be separated and matched with the limiting groove 163. When the second connecting member 32 is stopped by the limiting groove 163, the rotation of the support assembly 20 relative to the fixed plate 11 is limited, so that the support assembly 20 maintains the current position. When the first support portion 211 and the second support portion 212 need to be converted, the second connecting member 32 is moved toward the bushing 31 by an external force and separated from the limiting plate 16. After the support assembly 20 is rotated, the first support portion 211 and the second support portion 212 are interchanged, and the second connecting member 32 is again matched with the corresponding limiting groove 163 to achieve limiting to maintain the current position. Therefore, by the cooperation of the second connecting member 32 and the limiting groove 163, it is convenient to limit the second connecting member 32, and when the support assembly 20 is rotated to the specified position, it can be prevented from rotating, and the current position is maintained to facilitate adaptation to support different vehicle bodies.

[0055] In some embodiments, Figure 4As shown, the limiting plate 16 includes: a first limiting portion 161 and a second limiting portion 162. The first limiting portion 161 abuts against the fixed plate 11; the second limiting portion 162 is arranged at both ends of the first limiting portion 161, the second limiting portion 162 is spaced apart from the fixed plate 11, and a limiting groove 163 is arranged on the second limiting portion 162. The first limiting portion 161 and the second limiting portion 162 are arranged at different heights on the height of the support structure 2. The second limiting portion 162 is arranged at at least one end of the first limiting portion 161. When the first limiting portion 161 abuts against the fixed plate 11, the second limiting portion 162 is spaced apart from the fixed plate 11, and a limiting groove 163 is arranged on the second limiting portion 162. In this way, when the limiting plate 16 is required to rotate with the first connecting member 13, the second connecting member 32 has space to move in the height direction of the supporting structure 2, so as to facilitate the rotation and limiting of the limiting assembly 30. At the same time, the first limiting portion 161 abuts against the fixing plate 11 , which can increase the compactness and reliability of the entire supporting structure 2 .

[0056] Optionally, refer to Figure 4 There are two second limiting parts 162, and the two second limiting parts 162 include a first sub-limiting part and a second sub-limiting part, and the first sub-limiting part and the second sub-limiting part both form a limiting groove 163; there are two second connecting members 32, and the two second connecting members 32 are respectively detachably matched with the limiting grooves 163 corresponding to the two first sub-limiting parts and the second sub-limiting parts. The two limiting grooves 163 are respectively the first sub-limiting groove and the second sub-limiting groove, wherein the first sub-limiting groove is arranged on the first sub-limiting part, and the second sub-limiting groove is arranged on the second sub-limiting part.

[0057] When one of the two second connectors 32 cooperates with the limiting groove 163 of one of the first sub-limiting part and the second sub-limiting part, the other of the two second connectors 32 cooperates with the limiting groove 163 of the other of the first sub-limiting part and the second sub-limiting part. For example, there are two limiting assemblies 30, and both limiting assemblies 30 include second connectors 32, and the two second connectors 32 include a first sub-connector and a second sub-connector. When the first sub-connector cooperates with the first sub-limiting groove and the second sub-connector cooperates with the second sub-limiting groove, the first support portion 211 is used to support the vehicle body; when the second sub-connector cooperates with the first sub-limiting groove and the first sub-connector cooperates with the second sub-limiting groove, the second support portion 212 is used to support the vehicle body. The first sub-connector and the second sub-connector can realize the position conversion under the action of external force, that is, the support structure 2 can rotate 180°.

[0058] Optionally, in some embodiments, the limiting plate 16 has four limiting grooves 163, and the limiting grooves 163 are arranged at intervals along the circumferential direction, so that the support structure can be rotated 290 degrees on the basis of the existing ones.

[0059] In some embodiments, Figure 4As shown, a limiting hole 164 is formed on the first limiting portion 161, and one end of the first connector 13 away from the support assembly 20 cooperates with the limiting hole 164; the limiting assembly 30 also includes: a limiting pin, which penetrates the limiting plate 16 in a direction perpendicular to the first connector 13 and cooperates with the first connector 13. That is, a limiting hole 164 is formed on the limiting plate 16, and the first connector 13 cooperates with the limiting hole 164 and extends into the limiting hole 164. The limiting pin penetrates the limiting plate 16 in the width direction of the support structure 2 and cooperates with the first connector 13, so as to limit the first connector 13 in the height direction of the support structure 2 and prevent the first connector 13 from coming out of the limiting plate 16. The matching structure of the limiting pin and the first connector 13 is relatively simple, which facilitates the disassembly of the first connector 13.

The support structure 2 can select the first support part 211 and the second support part 212 to contact the vehicle body according to the vehicle body model to achieve lifting of different vehicle bodies, so that the lifting device 1 can lift a variety of vehicle models.

[0062] In addition, if Figure 5 As shown, this embodiment also includes a rear support structure, which includes a support portion 4 and a connecting portion 5. The support portion 4 is arranged on the connecting portion 5, and the support portion 4 is connected to the frame 3 through the connecting portion 5.
