[0026] See also Figure 1 to Figure 2 , Figure 1 FIG. 1 shows a schematic structural diagram of the skid assembly provided in this embodiment. Figure 2 FIG. 2 shows a top view of the skid assembly provided in this embodiment, like Figure 1 and Figure 2 As shown, the present embodiment provides a skid assembly 10. It should be noted that the skid assembly 10 can be used in vehicle production to carry heavy objects and large components, reduce manpower burden and improve efficiency. Of course, it can also be used in other fields, such as aerospace equipment, ship-related structure production, etc. For different fields, the support point position of the skid assembly 10 can be adjusted to adapt to the application. The skid assembly 10 includes a switching power component 100, a skid bracket component 200 and a skid base component 300. The skid base component 300 may include but is not limited to a frame, a power mechanism, a transmission mechanism, etc. Since the skid base component 300 is a conventional device, its specific structure and working principle will not be elaborated here.

[0027] In one example, two sled bracket assemblies 200 are mirror-imaged on the top surface of the sled base assembly 300. In actual application, the working principle is that when the frame needs to be transferred to the sled, the sled bracket of the sled bracket assembly 200 needs to be switched from the horizontal direction to the vertical direction, and then the frame is placed, and the top of the sled bracket supports and fixes the frame. After the frame is transferred, the sled bracket needs to be switched from the vertical direction to the horizontal direction to avoid interference during the operation of the sled assembly 10. The switching power assembly 100 and the sled bracket assembly 200 are set on the same horizontal line. Through the setting of the switching power assembly 100, the switching power assembly 100 realizes the linkage control of the sled bracket assembly 200, realizes the automatic switching of the sled bracket assembly 200, saves labor costs, improves work efficiency, and effectively avoids errors during the operation of the sled assembly.

[0028] The specific structure and working principle of the switching power assembly and the sled bracket assembly will be further described below through multiple embodiments.

[0029] See also Figures 3 to 7 , Figure 3 shows a schematic diagram of the structure of the switching power assembly provided in this embodiment, Figure 4 Another structural schematic diagram of the switching power assembly provided in this embodiment is shown. Figure 5 FIG. 1 shows a partial structural schematic diagram of the switching power assembly provided in this embodiment, Figure 6 FIG. 2 shows another part of the structural schematic diagram of the switching power assembly provided in this embodiment. Figure 7 A schematic diagram of the structure of the top supporting plate provided in this embodiment is shown; like Figure 3 and Figure 4 As shown, the switching power assembly 100 is arranged on one side of the sled bracket assembly 200. The switching power assembly 100 is used for power support during the process of the sled bracket being laid down or erected. The switching power assembly 100 includes a support seat 110 and a mounting frame 120 arranged on the top of the support seat 110. A lifting mechanism 130 and a telescopic mechanism 140 are installed on the mounting frame 120. The lifting mechanism 130 and the telescopic mechanism 140 are used for the azimuth switching and rotation control of the sled bracket assembly 200.

[0030] Optionally, the support seat 110 includes a support frame 111 and a connecting rod 112 arranged on the support frame 111. The structure of the support frame 111 can be a frame welded from I-beams, or can be other materials and other structures, which are not limited here. The connecting rod 112 can be arranged in groups on the top of the support seat 110, which can be used for connecting, fixing and height adjustment of the installation frame 120.

[0031] Optionally, the mounting frame 120 can be a rectangular frame, including a base plate 121, a back plate 122 vertically connected to the base plate 121, and side panels 123 can be arranged on both sides of the base plate 121 to enclose a semi-enclosed rectangular frame. In this way, not only can other components in the mounting frame 120 be better protected, but also installation is more convenient. A connecting leg 1211 can be arranged on the bottom surface of the base plate 121, and the connecting leg 1211 can be provided with a through hole so as to cooperate with the connecting rod 112 to realize the connection and fixation of the mounting frame 120 and the support seat 110 as well as height adjustment.

[0032] In one example, for the convenience of description, the height direction A of the support frame 111 is defined as the first direction, and the length direction B of the support frame 111 is defined as the second direction. It should be noted that the definition of the direction does not limit the device structure, but is only used for the descriptive role of the structure in this embodiment. The lifting mechanism 130 is arranged on the surface of the mounting frame 120. The lifting mechanism 130 includes: a first cylinder 131 and a sliding plate 132. The first cylinder 131 is fixedly mounted on the surface of the mounting back plate 122. A first slide rail 1221 is arranged on the surface of the back plate 122 along the first direction. The first slide rail 1221 can be arranged in groups. The sliding plate 132 is fixedly connected to the output end of the first cylinder 131. At the same time, the bottom surface of the sliding plate 132 is slidably connected to the first slide rail 1221. When the first cylinder 131 is in operation, the sliding plate 132 slides along the first direction, and the first direction is the height direction of the mounting frame 120. Optionally, in order to buffer and limit the lifting mechanism 130 during the production process, a buffer block 1222 is arranged on the surface of the back plate 122 near the sliding plate 132. The buffer block 1222 can be mirrored. The material of the buffer block 1222 can be selected according to actual needs. For example, it can be a rubber material, which is not limited here.

[0033] In one example, the telescopic mechanism 140 is disposed on the surface of the sliding plate 132, and the telescopic mechanism 140 is configured to be used for rotation control of the sled bracket assembly 200. Specifically, a second slide rail 133 is disposed on the surface of the sliding plate 132 along the second direction, and the surface of the sliding plate 132 close to the second slide rail 133 is disposed on the first mounting block 1323, and the first mounting block 1323 is provided with a through hole along the second direction. The telescopic mechanism 140 includes: a top support plate 141, which is slidingly connected to the second slide rail 133; a second cylinder 142, and one end of the second cylinder 142 is fixedly connected to the first mounting block 1323 along the second direction, and the output shaft passes through the through hole and is fixedly connected to one end of the top support plate 141.

[0034] Optionally, a window 1231 may be provided on the side panel 123 at the telescopic end of the top support plate 141, and the top support plate 141 passes through the window 1231 when telescoping. In this way, while avoiding interference between the telescoping and extension of the top support plate 141, the setting of the side panel 123 can provide better protection for the telescopic mechanism 140.

[0035] In one example, a wedge block 1412 is provided near the end of the top support plate 141 connected to the output shaft. The wedge block 1412 can be a triangle or a rectangular block, which is selected according to actual needs and is not limited here. A notch 1413 is provided on the top surface of the top support plate 141 near the wedge block 1412, and a lifting slope 1414 is provided on the side opposite to the notch 1413 and the wedge block 1412, wherein the notch 1413 is configured to be selectively locked with the support handle 2111 and pulled up to allow the sled bracket to rotate and complete the azimuth switching, and the lifting slope 1414 is configured to continuously resist and squeeze the support handle 2111 to allow the pulley 2112 to slide out of the limiting groove 2213.

[0036] Optionally, the notch 1413 may be a chamfer formed by one side surface of the wedge block 1412 and the top surface of the top support plate 141. It should be noted that the specific shape of the notch 1413 may be selected according to actual needs, and the notch 1413 must be able to control the rotation of the sled support assembly 200 after cooperating with the support handle 2111 on the sled support assembly 200.

[0037] Optionally, for the lifting slope 1414, its angle with the second direction can be 10° to 60°, preferably 30° or 45°, and a second mounting block 1411 is provided on the surface adjacent to the plane where the notch 1413 is located, and the second mounting block 1411 is fixedly connected to the output shaft of the second cylinder 142.

[0038] See also Figures 8 to 10 , Figure 8 FIG. 1 shows a schematic structural diagram of the sled bracket assembly provided in this embodiment. Fig. 9 Another structural schematic diagram of the sled support assembly provided in this embodiment is shown. Fig.10 A partial structural schematic diagram of the sled support assembly provided in this embodiment is shown.

[0039] like Figures 8 to 9 As shown, the sled bracket assembly 200 is used to support the automobile frame. The sled bracket assembly 200 includes a bracket mechanism 210 and a rotating shaft mechanism 220 movably connected to the bracket mechanism 210. The bracket mechanism 210 is used to support the automobile frame. The rotating shaft mechanism 220 can be installed on the top surface of the sled base assembly 300. The bracket mechanism 210 includes a base, two spaced support plates 211 are fixedly connected to the base, a rotating shaft 222 is arranged between the two support plates 211, and both ends of the rotating shaft 222 are respectively rotatably connected to the support plates 211. A second connecting block 223 is coaxially sleeved on the surface of the rotating shaft 222, and the second connecting block 223 can rotate around the rotating shaft 222.

[0040] Optionally, at least one support plate 211 is provided with a supporting portion 2211, a curved surface 2212 and a limiting groove 2213 in sequence on one end face close to the bracket mechanism 210, wherein both ends of the curved surface 2212 extend to the supporting portion 2211 and the limiting groove 2213 respectively, and the supporting portion 2211 can be a chamfered or upwardly open curved groove. The structure of the supporting portion 2211 is selected according to actual needs and is not limited here. The angle between the supporting portion 2211, the limiting groove 2213 and the rotating shaft 222 is preferably 90°, so that the bracket mechanism 210 can be rotated from a horizontal state to a vertical state. Of course, the specific angle can also be selected according to actual needs and is not limited to 90°.

[0041] Optionally, the bracket mechanism 210 includes a first connecting block 211 and a bracket body 212, one end of the bracket body 212 is fixedly connected to the first connecting block 211, and the other end of the bracket body 212 is provided with a supporting surface for supporting the frame. The structure of the supporting surface can be selected according to actual needs and is not limited here.

[0042] It should be noted that a sliding rod 2113 is provided on the end face of the first connecting block 211 away from the bracket body 212, and a limiting hole 2231 is penetrated through the second connecting block 223. The limiting hole 2231 is perpendicular to the direction of the rotation axis and is staggered. The number of limiting holes 2231 and the sliding rod 2113 is the same, and the sliding rod 2113 is penetrated into the limiting hole 2231. The sliding rod 2113 can slide along the direction of the limiting hole 2231, but the sliding distance of the sliding rod 2113 is limited. The limiting method can be to set a spring between the limiting hole 2231 and the opposite end face of the sliding rod 2113, so that the sliding distance of the sliding rod 2113 is limited, thereby avoiding the bracket mechanism 210 from being disconnected from the first connecting block 211.

[0043] In this way, when the support mechanism 210 is in the vertical direction and needs to be switched to the horizontal direction, when the top support plate 141 is continuously driven to move forward, the lifting slope 1414 contacts and squeezes the support handle 2111, and the support mechanism 210 is limited and slidably connected with the first connecting block 211, and the support mechanism is slowly lifted upward, thereby driving the pulley to slowly slide out of the limiting groove 2213. After sliding out, the notch 1413 cooperates with the support handle to ensure the stability of the support mechanism 210, and at the same time, prevent the support mechanism 210 from being disconnected from the first connecting block 211.

[0044] Optionally, a support handle 2111 and a pulley 2112 are spaced apart on the side end face of the first connecting block 211. The support handle 2111 is used as a connection point for the supporting plate 141 when the linkage bracket mechanism 210 rotates. The pulley 2112 abuts against an arcuate surface 2212 on the end face of the supporting plate 211. Thus, when the bracket mechanism 210 rotates, the setting of the pulley 2112 can reduce the friction force during the rotation process of the bracket mechanism 210. The setting of the arcuate surface 2212 enables the pulley 2112 to switch its position between the abutment portion 2211 and the limiting groove 2213.

[0045] The above-mentioned device for switching the orientation of the sled support is provided by configuring the sled support assembly 200 to be a support mechanism 210 and a rotating shaft mechanism 220, wherein the support mechanism 210 and the rotating shaft mechanism 220 are limitedly slidably connected, and abutting portions 2211, arcuate surfaces 2212 and limiting grooves 2213 are provided on the surface of the support plate 221 of the rotating shaft mechanism 220, and a pulley 2112 and a support handle 2111 are provided on the surface of one side end of the support mechanism 220, and the pulley 2112 abuts against the arcuate surface 2212. When in operation, By switching the telescopic mechanism of the power assembly 100, the top support plate 141 is extended to the bottom of the support handle 2111, and then the lifting mechanism 130 drives the top support plate 141 to move upward, so that the notch of the top support plate 141 cooperates with the support handle, and then the top support plate 141 is moved upward and retracted at the same time by controlling the cylinder. At this time, the pulley 2112 rotates along the arc surface 2212, thereby driving the rotation of the bracket mechanism 210. When the pulley 2112 slides into the limit groove 2213, the automatic switching of the sled bracket from horizontal to vertical is completed.

[0046] At the same time, by setting a lifting slope 1414 on one end face of the notch 1413 on the top surface of the top supporting plate 141, when the bracket mechanism 210 needs to be laid down, the top supporting plate 141 is continuously pushed forward, and the lifting slope 1414 contacts and squeezes the support handle 2111. Since the bracket mechanism 210 is limited and slidably connected with the rotating shaft mechanism 220, the bracket mechanism 210 is slowly lifted upward, thereby driving the pulley 2112 to slowly slide out of the limit groove 2213. After sliding out, the notch 1413 cooperates with the support handle 2111 to ensure the stability of the bracket mechanism 210. Then, by controlling the first cylinder 131 and the second cylinder 142, the top supporting plate 141 moves downward and extends outward at the same time, thereby slowly completing the automatic switching of the bracket mechanism 210 from vertical to horizontal. In this way, the automatic switching of the sled bracket orientation saves labor costs, improves work efficiency, and effectively avoids errors during the operation of the sled assembly.
