[0036] The utility model provides a supporting mechanism and a trolley, aiming to solve the problems of complex structure, high manufacturing cost and high failure rate of the supporting mechanism in the prior art.

[0037] The embodiment of the utility model provides a supporting mechanism, such as Figures 1 to 4 As shown, the supporting mechanism includes a bracket 100 and a plurality of supporting units 200, each of which includes a mounting rod 210 rotatably disposed on the bracket 100, a supporting member 220 and a counterweight member 230 disposed on the mounting rod 210, the plurality of mounting rods 210 are spaced apart along the vertical direction of the bracket 100, each mounting rod 210 has a fully open position, a semi-open position and a closed position, the supporting member 220 and the counterweight member 230 are respectively located on both sides of the rotation axis of the mounting rod 210; the counterweight member 230 can drive the mounting rod 210 to rotate from the fully open position to the semi-open position to the closed position; when the mounting rod 210 located below rotates from the semi-open position to the fully open position, the corresponding counterweight member 230 can push the upper adjacent counterweight member 230 to rotate the upper adjacent mounting rod 210 from the closed position to the semi-open position.

[0038] In an embodiment of the utility model, the supporting member 220 of the supporting unit 200 is used to carry a workpiece (such as a sunroof of a car, etc.); the counterweight 230 is used to drive the mounting rod 210 to rotate from a fully open position to a semi-open position to a closed position, that is, after the workpiece is removed from the supporting member 220, the mounting rod 210 will rotate from a fully open position to a semi-open position to a closed position under the gravity of the counterweight 230, thereby realizing automatic closing of the support, which is convenient for the staff to continue to take the workpiece below; when the workpiece is placed on the supporting member 220 located below, the supporting member 220 will be affected by the gravity of the workpiece, and will drive the corresponding mounting rod 210 to rotate from a semi-open position to a fully open position. At this time, the counterweight 230 on the corresponding mounting rod 210 can push the upper adjacent counterweight 230 to move, so that the upper adjacent mounting rod 210 rotates from a closed position to a semi-open position, thereby realizing automatic opening of the support, which is convenient for the staff to continue to place the workpiece on the upper supporting unit 200. In the related art, the supporting mechanism usually needs to be equipped with an additional driving mechanism (such as a motor, a cylinder, etc.) to provide power for the supporting mechanism and realize the automatic opening and closing of the support. However, due to space and structural limitations, the driving mechanism is difficult to simplify, which will lead to a complex structure of the supporting mechanism, increased manufacturing costs, and the configuration of an additional driving mechanism will increase the failure rate of the supporting mechanism. The supporting mechanism uses the principle of leverage and a purely mechanical structure to realize the automatic opening and closing of the support, which can simplify the structure of the supporting mechanism and reduce production costs. At the same time, it does not need to be equipped with an additional driving mechanism, which can effectively reduce the failure rate of the supporting mechanism. In addition, compared with the supporting mechanism that is manually opened and closed, the supporting mechanism can improve work efficiency and reduce the labor intensity of the staff.

[0039] like Figure 2 and Figure 4 As shown, the counterweight 230 includes a counterweight block 231 and a push block 232. The counterweight block 231 is connected to the mounting rod 210. The push block 232 is arranged on the counterweight block 231, and the push block 232 located below can abut against the counterweight block 231 adjacent to the top. When placing the workpiece on the supporting member 220 below, the mounting rod 210 will rotate from a semi-open position to a fully open position. At this time, the push block 232 located below abuts against the counterweight block 231 adjacent to the top and slides on the surface of the counterweight block 231 to push the counterweight block 231 above, so that the mounting rod 210 above rotates from the closed position to the open position, realizing the automatic opening of the support, which is convenient for the staff to place the workpiece on the supporting unit 200 above.

[0040] like Figure 2 and Figure 4As shown, a rotating abutment block 2321 is provided on the push block 232, and the abutment block 2321 located at the bottom can abut against the counterweight block 231 located above. By the abutment of the rotating abutment block 2321 with the counterweight block 231, the wear between the abutment block 2321 and the counterweight block 231 can be reduced, and the service life of the supporting mechanism can be extended; in this embodiment, the abutment block 2321 uses a bearing, and the outer circumferential surface of the bearing can abut against the counterweight block 231 located above. In addition, the abutment block 2321 can also use a part with an arc surface as the outer circumferential surface, such as a roller, which only needs to make the abutment block 2321 slide on the surface of the counterweight block 231 and push the counterweight block 231.

[0041] In one embodiment, if Figure 2 As shown, the supporting member 220 is a rubber block 221. The supporting member 220 is made of rubber material. When the supporting member 220 carries the workpiece, the contact part with the workpiece is made of rubber material, which can effectively protect the workpiece and prevent the workpiece from being scratched. In addition, the supporting member 220 can also be made of nylon material.

[0042] In another embodiment, if Figure 4 As shown, the supporting member 220 includes a rubber block 221, a fixed block 222 and a spring 223. The fixed block 222 is connected to the mounting rod 210. The rubber block 221 is slidably arranged on one side of the fixed block 222. The spring 223 connects the fixed block 222 and the rubber block 221. When the supporting member 220 carries the workpiece, the rubber block 221 contacts the workpiece, that is, when the supporting member 220 carries the workpiece, the contact part with the workpiece is made of rubber material, which can effectively protect the workpiece and avoid scratching the workpiece; the rubber block 221 is slidably arranged on the mounting rod 210, and the rubber block 221 and the fixed block 222 are connected by the spring 223. In the process of placing the workpiece, the position of the rubber block 221 can be adaptively adjusted by the expansion and contraction of the spring 223. In this embodiment, the rubber block 221 can be designed into a variety of different shapes to adapt to workpieces of different structures.

[0043] like Figure 3As shown, a first limit block 211 is disposed above each mounting rod 210; when the mounting rod 210 rotates from the semi-open position to the fully-open position, the first limit block 211 can abut against the counterweight 230; when the mounting rod 210 rotates from the semi-open position to the closed position, the first limit block 211 can abut against the mounting rod 210. When the mounting rod 210 rotates from the semi-open position to the fully-open position, the first limit block 211 can abut against the counterweight 230 to limit the position of the counterweight 230, thereby limiting the position of the mounting rod 210, thereby preventing the mounting rod 210 from being separated from the fully-open position due to an excessively large rotation angle, and at the same time, the stability of the supporting member 220 when carrying a workpiece can be ensured; when the mounting rod 210 rotates from the semi-open position to the closed position, the first limit block 211 can abut against the mounting rod 210 to limit the position of the mounting rod 210, thereby preventing the mounting rod 210 from being separated from the closed position due to an excessively large rotation angle.

[0044] A second limit block is provided on one side of the first limit block 211 at the bottom, and when the bottom mounting rod 210 rotates from the fully open position to the half-open position, the second limit block can abut against the mounting rod 210. The second limit block can abut against the mounting rod 210 when the bottom mounting rod 210 rotates to the half-open position, and restrict the mounting rod 210 to the half-open position, so that the staff can place the workpiece on the bottom supporting unit 200.

[0045] like Figure 1 As shown, the supporting mechanism also includes a cover body 300, and the cover body 300 is arranged on the bracket 100, and the end of the mounting rod 210 away from the supporting member 220 and the counterweight 230 are both accommodated in the cover body 300. Accommodating the end of the mounting rod 210 away from the supporting member 220 and the counterweight 230 in the cover body 300 can prevent the staff from contacting the counterweight part of the supporting mechanism, thereby ensuring the safety of the staff. In this embodiment, the cover body 300 is made of a transparent material (such as an acrylic plate), which is convenient for the staff to observe the movement of the supporting unit 200 more directly, so as to ensure that there is no interference during subsequent inspections and confirmation of movement. And, as Figure 2 and Figure 4 As shown, the mounting rod 210 is provided with a rotating shaft 212, and the rotating shaft 212 is rotatably arranged on the bracket 100 through a bearing. The rotating shaft 212 of the mounting rod 210 is connected to the bracket 100 through a bearing, which can reduce the friction between the rotating shaft 212 and the bracket 100 and improve the service life of the supporting mechanism.

[0046] In the embodiment of the utility model, the supporting mechanism has two embodiments, and the difference between the two embodiments lies in the structure of the supporting member 220; in the first embodiment, as Figure 2 As shown, the supporting member 220 is a rubber block 221, and the supporting member 220 is made of rubber material, which can effectively protect the workpiece and prevent the workpiece from being scratched; in the second embodiment, as shown in FIG. Figure 4 As shown, the supporting member 220 includes a rubber block 221 , a fixing block 222 and a spring 223 . The rubber block 221 is used to support the workpiece, which can effectively protect the workpiece and prevent it from being scratched. At the same time, the position of the rubber block 221 can be adaptively adjusted by the expansion and contraction of the spring 223 .

[0047] In addition, the embodiment of the utility model also provides a trolley, such as Figure 5 As shown, the trolley includes a frame 400 and the supporting mechanism as described above, the number of the supporting mechanisms is four, and the four supporting mechanisms are rectangularly arranged on the frame 400. In this embodiment, two of the four supporting mechanisms adopt the structural form of the first embodiment, and the other two adopt the structural form of the second embodiment, and the two supporting mechanisms adopting the structural form of the first embodiment are arranged one-to-one with the two supporting mechanisms adopting the structural form of the second embodiment.

[0048] Since the trolley includes the supporting mechanism as described above, the trolley has all the beneficial effects of the supporting mechanism, which will not be described in detail here.

[0049] like Figure 5 As shown, a synchronization rod 500 is disposed between the supporting units 200 of two supporting mechanisms adjacent to each other along the first direction of the frame 400. The first direction refers to Figure 5 The synchronization rod 500 can make the supporting units 200 of two supporting mechanisms adjacent to each other along the first direction of the frame 400 move synchronously, that is, the two supporting units 200 adjacent to each other along the first direction of the frame 400 can be opened and closed simultaneously to ensure the stability of the supporting units 200 when carrying workpieces.

[0050] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
