Description

Technical Field

[0001] This utility model relates to the technical field of automobile manufacturing assembly line, and more specifically, to a foldable frame support device for a new energy vehicle co-production line. Background Technology

[0002] Currently, a production line can usually only complete the final assembly of one type of vehicle frame. This is because different frames have different structures, requiring production lines to have different corresponding support structures, and a production line with only one support structure cannot support different frames. For example... Figure 1 Model A requires a support system with three supports, while Model B requires a support system with four support points. Model A and Model B cannot be produced on the same production line.

[0003] To save on production line construction costs and achieve co-line production, one existing method is to replace the supports that differ in position between the two frames before assembling them. This involves either installing or removing the supports to match the number and position of the supports to the frame requirements. However, this method of removal or installation requires parts allocation and warehouse transportation, making the work quite cumbersome. Utility Model Content

[0004] The main purpose of this utility model is to provide a foldable frame support device for a new energy vehicle co-production line, so as to solve the problem that it is inconvenient to produce two models on the same line in the existing technology.

[0005] To achieve the above objectives, according to one aspect of the present invention, a foldable frame support device for a new energy vehicle co-production line is provided, comprising a first support structure, a second support structure, a third support structure, and a fourth support structure sequentially installed at the production line workstations.

[0006] The fourth support structure includes an upper support component and a lower support component, and the upper support component and the lower support component have two states: hinged connection and plug connection.

[0007] When the upper support component and the lower support component are in a hinged state, the upper support component can fold relative to the lower support component. When the upper support component and the lower support component are in a plugged state, the upper support component and the lower support component can be fixed to provide support.

[0008] The movable support square tube can be aligned vertically with the vertical support square tube as a support structure, or it can be folded down relative to the vertical support square tube when not in use. When producing Type A vehicles, the movable support square tube is folded inward to avoid interference during Type A vehicle production. When producing Type B vehicles, the vertical support square tube is erected and fixed to the lower support component, and is supported by the lower support component. The top of the movable support square tube can support the base of the Type B vehicle.

[0009] In a further improvement, the supporting lower component includes two vertical support square tubes and a crossbar connecting the two vertical support square tubes; a hinge hole is provided at the top of each vertical support square tube, and a limiting card interface is provided on the adjacent surface of the hinge surface.

[0010] The upper support component is made of square tubing, and there are two of them, each of which can be internally fitted into the vertical support square tubing, referred to as the movable support square tubing; the two sides of the lower part of the movable support square tubing are provided with long through holes for pin shafts to cooperate with the hinge holes of the vertical support square tubing, and are equipped with pin shafts; near the long through holes for pin shafts, a limiting block that cooperates with the limiting card interface is fixedly installed on the movable support square tubing.

[0011] As a further improvement, a polyurethane adhesive block is fixedly provided on the top of the movable support square tube.

[0012] As a further improvement, the crossbar of the supporting component is provided with an auxiliary fixing support to help fix the movable support square tube in the folded state.

[0013] In a further improvement, the auxiliary fixing support includes a support rod with an upper opening and a pin hole.

[0014] As a further improvement, the auxiliary fixing support is equipped with a spring-loaded limiting pin to cooperate with the pin hole.

[0015] A further improvement is made by creating a through hole for the movable support square tube, which is designed to cooperate with the spring-loaded limiting pin.

[0016] The application of the technical solution of this utility model has the following technical effects: by modifying the frame support and adding a foldable fourth support structure, it is possible to produce two frames, A and B, on the same production line, thereby reducing production costs.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] like Figure 2-7 As shown, the foldable frame support device for a new energy vehicle co-production line includes a first support structure 1, a second support structure 2, a third support structure 3, and a fourth support structure 4, which are sequentially installed at the production line workstations. The first support structure 1, second support structure 2, and third support structure 3 are the existing support structures and can be used to support Class A vehicles. The fourth support structure 4 is an additional support structure that, when in use, can support Class A vehicles together with the other three support structures; when not in use, it can be folded away to avoid interfering with Class A vehicles.

[0047] The fourth support structure includes two upper support components 5 and one lower support component 6. The lower support component 6 has two vertical support square tubes 61, which cooperate with the movable support square tubes 51 of the upper support components 5. The movable support square tubes 51 can be aligned with the vertical support square tubes 61 as a support structure as needed, or they can be folded down relative to the vertical support square tubes 61 when not in use.

[0048] The structure of the lower support component 6 and the upper support component 5 will be described in more detail below.

[0049] The supporting component 6 includes two vertical support square tubes 61 and a crossbar 62 connecting the two vertical support square tubes; each vertical support square tube 61 has a hinge hole 64 at its top and a limit card interface 63 on the adjacent side of the side where the hinge hole 64 is located.

[0050] The upper support component 5 includes two vertical support square tubes 51, with a vertical support square tube 61 sleeved inside each other. Two long through holes 52 for pins are opened on the lower sides of the movable support square tube, which mate with the hinge holes 64 of the vertical support square tubes, and are equipped with pins. A limiting block 53, which mates with the limiting card interface 63, is fixedly installed on the movable support square tube near the long through holes for pins. The top of the vertical support square tube 51 has a supporting iron plate 54, and a polyurethane adhesive block 55 is fixedly attached to the iron plate 54.

[0051] refer to Figure 3 The two states of the upper support component 5, and the process of using the upper support component 5 and the lower support component 6 together:

[0052] When the movable support square tube 51 and the vertical support square tube 61 are both in the vertical direction, the limiting block 53 of the movable support square tube 51 and the limiting locking interface 63 of the vertical support square tube 61 are engaged together, fixing the movable support square tube 51 to the vertical support square tube 61 and providing support from the vertical support square tube 61. The top of the movable support square tube 51 can support the base of a Class B vehicle.

[0053] When it is necessary to produce the Type A car, first move the movable support square tube 51 upward. The pin shaft through hole 52 of the movable support square tube 51 moves upward accordingly. The lower end of the pin shaft through hole 52 contacts the pin shaft to form a hinge surface. At this time, fold the movable support square tube 51 inward to avoid interference during the production of the Type A car.

[0054] To ensure the stability of the movable support square tube 51 in the folded state, a support base 65 is added to the upper surface of the crossbar 62. In this embodiment, the support base 65 is made of two parallel iron plates, with a support base pin hole and a pin at the top. A limiting pin through hole 56 corresponding to the hinge hole of the support base is opened at the corresponding position of the movable support square tube 51. When the movable support square tube 51 is in the folded state, it rests on the two iron plates of the support base 65 and is fixed by the spring-loaded limiting pin 66. The spring-loaded limiting pin 66 is movably mounted on sleeves open at both ends by a spring. The sleeves are installed at the pin hole position. Pulling the end of the pin disengages it from the pin hole, and releasing it allows it to retract into the pin hole.

[0055] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
