[0032] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples.

[0033] Reference below Figure 1-Figure 6 A hanger structure 200 for a vehicle body according to an embodiment of the present invention is described.
[0034] like Figure 1-Figure 4 As shown, the hanger structure 200 for a vehicle body according to an embodiment of the utility model comprises: a frame 10 , a positioning device 20 and a second positioning member 23 .
[0035] The positioning device 20 includes a base 21 and a first positioning member 22, the base 21 is connected to the frame 10, the first positioning member 22 is fixedly connected to the base 21, and the second positioning member 23 is movably connected to the positioning device 20, and the first positioning member 22 and the second positioning member 23 are respectively provided with a first positioning pin 221 and a second positioning pin 231 for positioning and cooperating with the vehicle body 100, wherein the second positioning member 23 has an expanded state and a retracted state, in which the second positioning pin 231 is located on a side of the first positioning pin 221 away from the base 21, and in the retracted state, the second positioning pin 231 is located on a side of the first positioning pin 221 close to the base 21.
[0036] Thus, the first positioning member 22 is fixed on the base 21, and the first positioning pin 221 on the first positioning member 22 can position the body 100 of some models, such as a large body 100, and the second positioning member 23 can move on the positioning device 20 so as to have an expanded state and a stored state. In this way, the second positioning member 23 can adapt to more models of body 100 when in the expanded state, such as a small body 100, so that the sling structure 200 can adapt to a variety of models and thus enable the same painting production line to paint a variety of models.
[0037] For example, the positioning device 20 is connected to the frame 10 through the base 21, and the base 21 and the frame 10 can be connected by bolts, which can ensure the connection stability between the positioning device 20 and the frame 10, so that the body 100 is not easy to fall from the lifting structure 200 when the lifting structure 200 is lifting the body 100, and the first positioning member 22 is fixedly connected to the base 21, so that the lifting structure 200 can adapt to some vehicle models, such as a large vehicle body 100, so that the first positioning pin 221 can directly position the body 100 of some vehicle models and can directly paint it.
[0038] Furthermore, the second positioning member 23 can be movably connected to the positioning device 20, so that the second positioning member 23 has an expanded state and a stored state. When the second positioning member 23 is in the expanded state, the second positioning pin 231 on the second positioning member 23 is located on the side of the first positioning pin 221 away from the base 21, so that the second positioning pin 231 can adapt to the body 100 of a small vehicle model so that the lifting structure 200 can lift the small vehicle body 100 for painting. In this way, the lifting structure 200 can lift various vehicle models 100 through the first positioning member 22 and the second positioning member 23, so that the same painting production line can adapt to various vehicle models and carry out painting.
[0039] According to the hanger structure 200 for the vehicle body according to the embodiment of the utility model, by setting the second positioning member 23, it is convenient to realize the positioning of the vehicle body 100 of different sizes by switching the state of the second positioning member 23, that is, the hanger structure 200 can adapt to vehicle bodies 100 of various models. At the same time, in the storage state, the second positioning pin 231 is located on the side of the first positioning pin 221 close to the base 21, which can avoid the interference of the second positioning pin 231 with the larger vehicle body 100. In this way, there is no need to replace the positioning device 20, which is conducive to simplifying the positioning process and improving the painting production efficiency.
[0040] In some embodiments, Figure 1-Figure 4 As shown, in the stored state, at least a portion of the second positioning member 23 is located below the first positioning member 22 .
[0041] Therefore, the second positioning member 23 will partially overlap with the first positioning member 22 when in the storage state, so that the second positioning member 23 occupies less space in the frame 10, so that when the first positioning member 22 is positioning the vehicle body 100 to be painted, the second positioning member 23 will not interfere with the vehicle body 100 to be painted, thereby making the connection of the hanger structure 200 to the vehicle body 100 to be painted more stable.
[0042] In some embodiments, Figure 1-Figure 4As shown, the second positioning member 23 includes a swing arm 232 , the swing arm 232 is rotatably connected to the first positioning member 22 via a rotating shaft 233 , and the second positioning pin 231 is disposed on the swing arm 232 .
[0043] Therefore, the swing arm 232 of the second positioning member 23 is rotatably connected to the first positioning member 22 through the rotating shaft 233, so that the second positioning member 23 can rotate on the first positioning member 22. At the same time, the second positioning pin 231 is arranged on the swing arm 232. When the second positioning member 23 swings, the position of the second positioning pin 231 relative to the base 21 will change, thereby ensuring that the second positioning member 23 can adapt to a variety of vehicle body 100 when unfolded.
[0044] In some embodiments, Figure 1-Figure 4 As shown, the second positioning member 23 is further provided with a push rod 234 , and the driving structure is suitable for driving the push rod 234 to drive the swing arm 232 to rotate around the rotating shaft 233 .
[0045] Therefore, the driving structure drives the swing arm 232 to rotate around the rotating shaft 233 by driving the push rod 234, so that the deployment and storage of the second positioning member 23 can be controlled, and the second positioning member 23 can be deployed or stored as needed when the sling structure 200 fixes the body 100 of different models.
[0046] In some embodiments, Figure 1-Figure 4 As shown, the push rod 234 and the second positioning pin 231 are respectively located on two sides of the rotating shaft 233.
[0047] Therefore, the push rod 234 and the second positioning pin 231 are distributed on the swing arm 232 and are located on both sides of the rotating shaft 233. When the driving structure drives the push rod 234, the movement direction of the second positioning pin 231 is opposite to that of the push rod 234. When the second positioning pin 231 moves to the specified position, it cooperates with the positioning hole of the vehicle body 100.
[0048] In some embodiments, Figure 1-Figure 4 As shown, the second positioning member 23 also includes: a limiting component 24, which is connected to the positioning device 20 and includes a first limiting component 241 and a second limiting component 242. In the expanded state, the first limiting component 241 cooperates with the second positioning member 23 in a limiting manner, and in the stored state, the second limiting component 242 cooperates with the second positioning member 23 in a limiting manner.
[0049] Therefore, the second positioning member 23 is ensured not to move arbitrarily by setting the limit assembly 24, thereby ensuring that there will be no problems with the sling structure 200 during use. For example, in the unfolded state, the first limit member 241 and the second positioning member 23 are limited and cooperated, so that the second positioning member 23 can be maintained in the unfolded state, so that the sling structure 200 can sling the small vehicle body 100. In the stored state, the second limit member 242 and the second positioning member 23 are limited and cooperated, so that the second positioning member 23 can be maintained in the stored state and will not interfere with the large vehicle body 100 hoisted by the sling structure 200.
[0050] In some embodiments, Figure 1-Figure 4 As shown, the swing arm 232 is provided with a first limiting hole and a second limiting hole, the first limiting member 241 is suitable for being inserted into the first limiting hole, and the second limiting member 242 is suitable for being inserted into the second limiting hole.
[0051] Therefore, the first limiting hole and the second limiting hole on the swing arm 232 are used to connect the first positioning member 22 and the second positioning member 23, so as to ensure that the second positioning member 23 can be fixed when in different states, thereby ensuring the use of the sling structure 200.
[0052] For example, when the second positioning member 23 is in the expanded state, the first limiting hole will be opposite to the first positioning member 22. At this time, the first positioning member 22 can be inserted into the first limiting hole to fix the second positioning member 23. When the second positioning member 23 is in the stored state, the second limiting hole will be opposite to the second positioning member 23. At this time, the second positioning member 23 can be inserted into the second positioning hole. In this way, the second positioning member 23 will not move at will when it is in the expanded state or the stored state.
[0053] In some embodiments, Figure 1-Figure 4 As shown, the first limiting member 241 and the second limiting member 242 can be retractably installed on the positioning device 20, and the limiting assembly 24 also includes an operating rod 243, which is used to control the extension or retraction of the first limiting member 241 and the second limiting member 242.
[0054] Therefore, the operating rod 243 can control the extension or retraction of the first limiting member 241 and the second limiting member 242. In this way, when the second positioning member 23 is in the expanded state or the stored state, the operating rod can control the extension or retraction of the first limiting member 241 or the second limiting member 242, thereby ensuring that the second positioning member 23 is in a locked or unlocked state.
[0055] In some embodiments, the sling structure 200 further includes: a photoelectric detection component, which is installed on the second positioning pin 231 and is suitable for communication connection with the operating rod 243 .
[0056] Therefore, the photoelectric detection component installed on the second positioning pin 231 can detect the position between the second positioning pin 231 and the positioning hole of the vehicle body 100 when the second positioning component 23 is in the expanded state, thereby judging whether the second positioning component 23 is expanded into place. When the second positioning pin 231 is directly opposite to the positioning hole of the vehicle body 100, the operating rod 243 will control the second limiting component 242 to extend and insert into the second limiting hole.
[0057] In some embodiments, Figure 1 As shown, there are two groups of positioning devices 20, which are respectively a front positioning device 25 and a rear positioning device 26. The front positioning device 25 and the rear positioning device 26 are respectively used to cooperate with the front and rear of the vehicle body 100, and the front positioning device 25 and / or the rear positioning device 26 are provided with a second positioning member 23.
[0058] Thus, the two groups of positioning devices 20 can better fix the vehicle body 100 in the sling structure 200. At the same time, the two groups of positioning devices 20 are divided into a front positioning device 25 and a rear positioning device 26. When the front positioning device 25 is provided with a second positioning member 23, the rear positioning device 26 is not provided with the second positioning member 23, or when the rear positioning device 26 is provided with a second positioning member 23, the front positioning device 25 is not provided with the second positioning member 23, or both the front positioning device 25 and the rear positioning device 26 are provided with the second positioning member 23. Preferably, in this embodiment, both the front positioning device 25 and the rear positioning device 26 are provided with the second positioning member 23.
[0059] According to the lifting device structure 200 for the vehicle body of the embodiment of the utility model, when the lifting device structure 200 is lifting the large vehicle body 100, the operating rod 243 will control the first limiting member 241 to extend into the first limiting hole, and at this time, the second positioning pin 231 is located on the side of the first positioning pin 221 close to the base 21, so that the first positioning pin 221 of the first positioning member 22 can position the large vehicle body 100, and the second positioning member 23 is in a storage state and will not interfere with the lifting of the large vehicle body 100, and the lifting device structure 200 is in a state of lifting the small vehicle body 100. 0, the operating rod 243 controls the first limiting member 241 to be retracted, and the driving structure drives the push rod 234 to make the second positioning member 23 rotate around the rotating shaft 233. The second positioning pin 231 will be located on the side of the first positioning pin 221 away from the base 21. When the photoelectric detection element on the second positioning pin 231 detects that the second positioning pin 231 is directly opposite to the positioning hole of the vehicle body 100, the operating rod 243 controls the second limiting member 242 to extend into the second limiting hole. In this way, the second positioning member 23 is in an expanded state, so that the lifting device structure 200 can lift the small vehicle body 100.
