[0028] In order to make the skilled in the art better understand the technical solutions of the present application, the present application is further described in detail below in combination with the drawings and specific embodiments.

[0029] In the embodiments of the present application, the terms "first" and "second" are mainly used to distinguish the same or similar features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0030] In the embodiments of the present application, the front-rear direction refers to the direction relative to the body when the repairer sits on the lying board vehicle in a sitting position, the front of the body is the front in the embodiments of the present application, and the rear of the body is the rear in the embodiments of the present application; the up-down direction is the vertical direction. The left-right direction in the embodiments of the present application is defined as shown in the drawings, and the left-right direction is perpendicular to the front-rear direction and the vertical direction, and is also the left-right direction of the repairer himself when the repairer sits on the lying board vehicle in a sitting position. The left side or right side of the backrest part 1 and the seat board part 2 mentioned below is the side part mentioned in the embodiments of the present application. Figure 1

[0031] Please refer to Figure 1 , Figure 1 Fig. 1 is a structural schematic view of the lying board vehicle in the embodiments of the present application.

[0032] ​The lying board vehicle in the embodiment comprises a backrest part 1, a seat part 2 and a rotating mechanism 3. The backrest part 1 and the seat part 2 are connected by the rotating mechanism 3. In order to avoid interference in rotation, the backrest part 1 and the seat part 2 can not be in direct contact, and there is a gap between the lower part of the backrest part 1 and the rear part of the seat part 2. Figure 1

[0033] In detail, please continue to refer to Figure 2 , Figure 2 the structure diagram of the rotating mechanism 3 in the embodiment. Figure 1

[0034] The rotating mechanism 3 comprises a connecting rod 31, a mounting rod 32, a limiting disc 33 and a limiting pin 34. The connecting rod 31 is fixed to the side part of the backrest part 1, and specifically can be fixed to the side part of the backrest part 1 through a mounting block 35. The mounting rod 32 is fixed to the side part of the seat part 2, and the limiting disc 33 is fixed to the mounting rod 32. In this way, the connecting rod 31 forms an integral whole with the backrest part 1, and the mounting rod 32, the limiting disc 33 and the seat part 2 form an integral whole. When the connecting rod 31 rotates relative to the limiting disc 33, i.e. the backrest part 1 rotates relative to the seat part 2, the angle adjustment of the lying board vehicle is realized.

[0035] The connecting rod 31 is provided with a first limiting hole 31a, and the limiting disc 33 is provided with a plurality of second limiting holes 33a of the same size and distributed in the circumferential direction. The limiting pin 34 can be inserted into the first limiting hole 31a and a second limiting hole 33a corresponding to the first limiting hole 31a. After the backrest part 1 is rotated to a suitable angle, the limiting pin 34 is inserted into the corresponding first limiting hole 31a and second limiting hole 33a at this time, and the angle locking of the backrest part 1 can be realized. In order to prevent the limiting pin 34 from sliding out of the first limiting hole 31a and the second limiting hole 33a during repair, the limiting pin 34 can be threadedly connected with the first limiting hole 31a or the second limiting hole 33a, i.e. the limiting pin 34 can be a bolt, and the limiting pin 34 can be a light rod pin structure, and one end can be locked by a pin latch.

[0036] It should be noted that other connecting components such as ear seats can be added between the bottom of the backrest part 1 and the rear part of the seat part 2 in the embodiment without affecting the free rotation of the backrest part 1, and the purpose is only to make the rotation more smooth.

[0037] As shown in Figure 1 ​​As shown, the mounting rod 32 extends rearward into the seat plate 2, with one part of the mounting rod 32 connected to the side of the seat plate 2 and the other part located behind the seat plate 2. Support wheels 4 are provided at both the rear end of the mounting rod 32 and the front end of the seat plate 2, for a total of four support wheels 4. The rear end of the mounting rod 32 has a third support wheel mounting hole 32a, through which a pair of support wheels 4 are fixed to the mounting rods 32 on both sides. The seat plate 2 has second support wheel mounting holes 22a on both sides, through which another pair of support wheels 4 are fixed to the lower front end of the seat plate 2.

[0038] During the rotation of the backrest 1, the seat 2 does not move relative to the ground. The plane where the seat 2 is located is selected as the reference plane, meaning the seat 2 is the basis for the rotation of the backrest 1. Therefore, it is necessary to ensure the stability of the seat 2's support when the backrest 1 rotates. Here, the mounting rod 32 is extended rearward, and the support wheel 4 is set at the rear end of the mounting rod 32 extending beyond the seat 2. The mounting rod 32 and the seat 2 together serve as the basis for the flipping of the backrest 1. The center of gravity of the basis is extended rearward. When the backrest 1 is reclined (the angle between the backrest 1 and the seat 2 exceeds 90°), the support of the reclining cart is more stable and the balance is better, preventing the backrest 1 of the reclining cart from tipping backward due to an excessively large reclining angle.

[0039] Let's look again. Figure 2 ,from Figure 2 It is not difficult to see that the connecting rod 31 is a bent rod with a right angle. It can be divided into three segments, including a first connecting rod segment 311, a second connecting rod segment 312, and a third connecting rod segment 313 connected in sequence. The first connecting rod segment 311 and the third connecting rod segment 313 are parallel to each other, and the second connecting rod segment 312 is perpendicular to the first connecting rod segment 311 and the third connecting rod segment 313. The end of the first connecting rod segment 311 is fixedly connected to the side of the backrest 1 by a mounting block 35. The second connecting rod segment 312 is provided with a first connecting hole 31b, and the center of the limiting plate 33 is provided with a second connecting hole 33b (shown in...). Figure 2 The connecting rod 31 and the limiting plate 33 are hinged through the first connecting hole 31b and the second connecting hole 33b, thereby realizing the rotation of the connecting rod 31 relative to the limiting plate 33; the end of the third connecting rod segment 313 is provided with a first limiting hole 31a, which, as mentioned above, can cooperate with the limiting pin 34 and the second limiting hole 33a to lock the angle.

[0040] The connecting rod 31 is shaped as above, which can ensure that the hinge point of the second connecting rod segment 312 is the rotation center, and the first connecting rod segment 311 rotates together with the backrest part 1, and the third connecting rod segment 313 rotates relative to the limiting disc 33, which can ensure the concentric rotation of the first connecting rod segment 311 and the third connecting rod segment 313, and can also reduce the space occupied by the connecting rod 31. Obviously, the more the number of the second limiting holes 33a is, the higher the accuracy of the angle adjustment is. The number can be set according to actual needs.

[0041] As mentioned above, from Figure 2 it can be seen that the limiting disc 33 is not a complete circular disc structure, but a semicircular shape. This is because in this embodiment, it is not necessary to ensure that the backrest part 1 makes a complete circular rotation, but only needs to complete a 180° rotation relative to the seat plate part 2. The semicircular structure can ensure that the backrest part 1 rotates from the position folded on the seat plate part 2 to the position on the extension line of the rear side of the seat plate part 2, and can also save costs.

[0042] As Figure 2 shown, the limiting disc 33 has a first side and a second side, which are the left and right sides relative to the axis direction of the second limiting hole 33a. The first side is fixedly connected with the mounting rod 32, which can be connected by bolts or other fasteners, or can be welded. The second side of the limiting disc 33 is in contact with the connecting rod 31 to ensure the accuracy of the angle adjustment.

[0043] Continuing to understand Figure 2 , in this embodiment, the connecting rod 31 is located on the second side of the limiting disc 33, and the limiting disc 33 is fixed to the side of the mounting rod 32. When the side of the backrest part 1 and the seat plate part 2 are flush in the vertical direction, there will be a gap between the end of the connecting rod 31 connected with the backrest part 1 and the side of the backrest part 1 due to the spacing of the mounting rod 32 and the limiting disc 33. Therefore, the mounting block 35 can be used to connect the connecting rod 31 and the backrest part 1 to eliminate the gap. The sides of the backrest part 1 and the seat plate part 2 are arranged to be flush in the vertical direction, and the backrest part 1 and the seat plate part 2 can be folded and aligned.

[0044] Please continue to refer to Figure 1 , in this embodiment, the upper part of the backrest part 1 is provided with a handle 5, which facilitates pulling the lying board vehicle when the backrest part 1 is folded on the seat plate part 2. The lying board vehicle can be pulled by the supporting wheels 4 at the rear end of the mounting rod 32, or the entire lying board vehicle can be lifted by the handle 5 of the backrest part 1. The side of the seat plate part 2 is also provided with a handle 5, which can provide a gripping part for repair personnel when repairing, facilitate force application, and also facilitate safety during the maintenance process. The number and arrangement position of the handle 5 can be determined according to actual needs, and there is no excessive limitation.

[0045] In addition, in order to improve the work efficiency in the whole process, reduce the time of parts delivery or taking, the lying board vehicle also comprises a parts box 5, which can be used to store the spare parts required for maintenance. Thus, during the repair process, the repair personnel can conveniently take the spare parts from the parts box 5. The parts box 5 is detachably connected to the side of the seat plate part 2 through the threaded hole 6a on the parts box and the parts box mounting hole 22b located on the side of the seat plate part 2. In detail, different types of parts can be classified and placed in different parts boxes 5 according to the fault of the automobile. After determining the type of fault of the automobile, different parts boxes 5 can be replaced according to the actual needs, without the need to search for parts again, reducing the loss of parts and saving operation time. After the repair is completed, the parts box 5 can also be conveniently removed.

[0046] Of course, compared with Figure 1 the parts box 5 with an open top, the parts box 5 can also be designed as a closed box body, such as Figure 1 the parts box 5 in can be covered with a top cover. After covering the top cover, the parts in the parts box 5 will be sealed. Thus, after the repair is completed, the parts box 5 does not need to be removed, and the parts box 5 can always be installed on the lying board vehicle, which is more convenient.

[0047] Please continue to refer to Figure 1 and understand in combination with Figure 3 , Figure 3 for Figure 1 the schematic view of the backrest part 1 of the lying board vehicle in the folding state on the seat plate part 2.

[0048] The backrest part 1 comprises a backrest body 11, a first steel pipe 12 and a first cross pipe 13. The first steel pipe 12 is located on the left and right sides of the backrest body 11 and is not directly connected with the backrest body 11, and there can be a gap between the two. The first cross pipe 13 is perpendicular to the first steel pipe 12 and is fixedly connected with the backrest body 11 and the first steel pipes 12 on both sides. The length of the first cross pipe 13 should be greater than the distance between the two first steel pipes 12. In this way, the first cross pipe 13 connects the backrest body 11 and the first steel pipes 12 into a whole, which is firmly connected and can also widen the structure. Figure 3 In , the two ends of the backrest part 1 are provided with a first cross pipe 13.

[0049] Similarly, the seat plate part 2 comprises a seat plate body 21, a second steel pipe 22 and a second cross pipe 23. The second steel pipe 22 is located on the left and right sides of the seat plate body 21 and is not directly connected with the seat plate body 21, and there can be a gap between the two. The second cross pipe 23 is perpendicular to the second steel pipe 22 and is fixedly connected with the seat plate body 21 and the second steel pipes 22 on both sides. The length of the second cross pipe 23 should be greater than the distance between the two second steel pipes 22. In this way, the second cross pipe 23 connects the seat plate body 21 and the second steel pipes 22 into a whole, which is firmly connected and can also widen the structure.

[0050] In addition, the length of the first steel pipe 12 and the second steel pipe 22 needs to avoid being too long or too short. If too long, the first steel pipe 12 will interfere with the movement of the backrest part 1 and the second steel pipe 22 located on the side of the seat plate body 21, which may reduce the adjustable angle range and cause the card to be stuck at certain angles; if too short, the setting space of the rotating mechanism 3, the support wheel 4, the handle 5 and the parts box 6 may be limited. That is, the length of the first steel pipe 11 and the second steel pipe 22 can be designed according to actual needs to meet the space requirements and avoid rotation interference.

[0051] In the embodiment, the side of the backrest part 1 and the seat plate part 2 is provided with a steel pipe, which plays a role in strengthening the structural strength on the one hand, and is provided as a hollow pipe structure, which is beneficial to reduce the weight and facilitate carrying.

[0052] At this time, based on the support of the cross pipe and the side steel pipe, the backrest body 11 and the seat plate body 21 can both use soft cushions to improve the user experience of the operator, such as the backrest body 11 including a backrest soft cushion and the seat plate body 21 including a seat plate soft cushion. Of course, if the soft cushion material is relatively soft, the above-mentioned cross pipe is not enough to support, the backrest body 11 can also include a backrest skeleton for further support, and the seat plate body 21 includes a seat plate skeleton for further support. The backrest soft cushion can be fixed to the backrest skeleton, and the seat plate soft cushion can be fixed to the seat plate skeleton. When repairing, the upper limbs and head of the repairer are often placed on the backrest part 1, and the lower limbs are placed on the seat plate part 2. Such arrangement can improve the comfort of the repairer during repair and can ensure the long-term use of the backrest part 1 and the seat plate part 2.

[0053] As shown in Figure 2 The end of the limit pin 34 is provided with a pull ring 341, which can conveniently pull the limit pin 34 in and out of the first limit hole 31a and the second limit hole 33a to realize positioning.

[0054] Please refer to Figure 1 , one end of the backrest part 1 is close to the seat plate part 2, and part of the parts of the rotating mechanism 3 are arranged, the other end of the backrest part 1 is provided with a first support wheel mounting hole 12a, which is specifically arranged at the end of the first steel pipe 12, and a pair of support wheels 4 are arranged at the other end of the backrest part 1 through the first support wheel mounting hole 12a. The existence of the support wheel 4 can make the whole lying board vehicle completely unfold (the included angle between the backrest part 1 and the seat plate part 2 is 180°), support the backrest part 1 to the ground or working platform, etc., and help to improve the support stability of the lying board vehicle, and also make the whole lying board vehicle more smoothly move according to the needs.

[0055] The above merely preferred embodiments of the present application, it should be noted that for those of ordinary skill in the art, without departing from the principles of the present application, can make several improvements and refinements, these improvements and refinements should also be considered as the scope of protection of the present application.
