Description

Technical Field

[0001] The utility model relates to the technical field of battery tray transportation, in particular to a universal loading trolley. Background Art

[0002] With the changes in the overall environment of the automotive industry, the adjustment of industrial structure, and the increasing pressure on environmental protection, in addition to the existing new energy vehicle companies, more and more traditional vehicle companies have also begun to transform and seek more energy-saving and environmentally friendly production solutions. Since Tesla released its integrated casting technology in 2020, related technologies and supporting facilities have become more and more mature, the advantages have become more and more obvious, and the technical routes have gradually become clear. A large number of vehicle companies have begun to deploy in the field of integrated die-casting.

[0003] The advantage of integrated casting is that it can cast multiple stamped and welded parts in one go, and divide the car body chassis into three modules: front, middle, and rear. It consists of the front cabin, middle plate, and rear floor. It reconstructs the automotive parts supply chain, improves efficiency, and reduces costs. At present, the integrated die-casting field is basically concentrated in the front cabin and rear floor, and the middle plate is rarely involved. Due to the maturity of CTP technology, the middle plate is generally composed of battery packs, in which the battery trays are welded from profiles, especially large-sized battery trays exceeding 1500mm. There is basically no integrated die-casting field. However, with the continuous maturity of die-casting machines and mold technology, the integrated casting battery trays have increasingly prominent advantages in comprehensive performance, stable dimensions, high efficiency and low cost, and major manufacturers are also making layouts, such as Honda and Mercedes-Benz. After this large shell part is produced, the problem of parts loading and handling needs to be solved. Because there is basically no actual performance of integrated die-casting of large-sized battery trays, the solution of related parts loading trolleys is basically blank, and there is no reference performance.

[0004] In the past, most trolleys were developed based on the characteristics of parts and were suitable for specific part shapes. They had very poor versatility. Every time a new part was developed, a new loading trolley had to be redeveloped / modified and the old trolley had to be scrapped, which was very costly. This has always been a difficulty. The large-sized battery trays are heavy, large, and easy to deform, which exacerbates this difficulty. Utility Model Content

[0030] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0031] like Figure 1 As shown, it is a schematic diagram of the structure of a preferred embodiment of the universal loading trolley of the utility model, wherein the parts loaded by the universal loading trolley are preferably battery trays. The shape of the battery tray in the prior art can be approximately regarded as a flat rectangular parallelepiped, which is hollowed out in the middle and has a size of more than 1500mm.

[0032] This universal loading trolley includes a trolley body, which is preferably a cubic structure, specifically including a body 1 and wheels 2, wherein the wheels 2 are arranged below the body 1, and the body 1 is formed by splicing a bottom plate 13 and a plurality of transverse rods 11 and vertical rods 12, wherein the transverse rods 11 and the vertical rods 12 are installed on the bottom plate 13, that is, a frame structure is formed by the transverse rods 11 and the vertical rods 12, and the top surface and one of the side surfaces of the frame structure of this embodiment are not installed with the transverse rods 11 and the vertical rods 12, so that it is convenient to insert a battery tray from the top surface or one of the side surfaces, and the battery tray is vertically loaded in the trolley body, and each trolley body can load multiple battery trays.

[0033] The trolley body of the present embodiment includes a supporting mechanism 5 and a clamping mechanism 4, and the supporting mechanism 5 and the clamping mechanism 4 both include a plurality of them. The supporting mechanism 5 is detachably provided on the upper surface of the bottom plate 13, and can support the battery tray. The clamping mechanism 4 is detachably provided on the inner side wall of the trolley body, and can clamp the battery tray from both sides of the battery tray, so that the battery tray is located in the vertical direction, that is, the supporting mechanism 5 and the clamping mechanism 4 cooperate with each other to realize the vertical loading of the battery tray. For example, the supporting mechanism 5 is located at the bottom between the two clamping mechanisms 4.

[0034] It should be noted that the clamping mechanism 4 of this embodiment is located on two opposite side walls of the vehicle body 1 and is symmetrically arranged with respect to the vertical center axis of the vehicle body 1, so as to facilitate clamping and fixing the battery tray from both sides.

[0035] Specifically, Figure 1-3 As shown, the clamping mechanism 4 includes a positioning strip 41 and a clamping assembly 43. The positioning strip 41 is long and horizontally installed. It includes two pieces, which are located on opposite sides of the vehicle body 1 and are fixed by the slots on the vertical rod 12, close to the top of the vertical rod 12. The slot of the vertical rod 12 located in the middle part has a fixing plate 42, and the fixing plate 42 is installed on the slot by bolts to strengthen the connection strength between the positioning strip 41 and the vehicle body 1.

[0036] The clamping assembly 43 of this embodiment includes at least one, such as Figure 1 As shown, the number of the specific clamping assemblies 43 is determined according to the number of battery trays to be loaded, and there may be multiple clamping assemblies 43 . The clamping assemblies 43 are detachably disposed on the positioning bar 41 .

[0037] like Figure 1-3 As shown, the clamping assembly 43 includes front and rear positioning blocks 431 and a positioning rod 432. The positioning rod 432 is detachably mounted on one side of the front and rear positioning blocks 431. The opposite side of the front and rear positioning blocks 431 is detachably arranged on the positioning bar 41. The detachability here is preferably that the front and rear positioning blocks 431 are inserted into the sockets 411 of the positioning bar 41 (the positioning bar 41 has multiple sockets 411) to adapt to battery trays with different thickness / spacing / positioning requirements.

[0038] In detail, the front and rear positioning blocks 431 are of an angular structure, and a positioning column 433 is provided on the inner side, which is adapted to the socket 411 on the positioning strip 41. The positioning column 433 is inserted into the socket 411 of the positioning strip 41 to realize the installation of the front and rear positioning blocks 431 on the positioning strip 41, and the surface of the front and rear positioning blocks 431 is provided with a blind hole, and the end of the positioning rod 432 is inserted into the blind hole, preferably with a threaded connection, and then fixed by bolts. The positioning rods 432 of different lengths can be replaced according to the length size of the battery tray to meet the lateral positioning / fixing needs of battery trays of different sizes.

[0039] More specifically, Figure 1 , Figure 4 and Figure 5 As shown, the base plate 13 has mounting holes 131, which are located on the left and right sides of the base plate 13. The positioning slot 31 plate 3 is installed on the base plate 13 through the mounting holes 131. Pins or screws are inserted into the mounting holes 131 to achieve the purpose of fixing, thereby meeting the positioning needs of battery trays with different thickness / spacing / placement requirements.

[0040] like Figure 1As shown, the positioning slot 31 plate 3 is provided with a plurality of rows of slots 31, and the extension direction of each row of slots 31 is located below the straight line distance between two positioning strips 41. The support mechanisms 5 are arranged at a preset distance, that is, each positioning slot 31 plate 3 has a plurality of support mechanisms 5, such as Figure 1 As shown, in this embodiment, each row of positioning slots 31 on the plate 3 has four supporting mechanisms 5 .

[0041] like Figure 4 and Figure 5 As shown, the support mechanism 5 specifically includes a support gasket 51, a support positioning block 52 and a fixing pin 53. The support gasket 51 includes at least one block, which is stacked. The support positioning block 52 is placed on the upper surface of the support gasket 51, and the fixing pin 53 is inserted into the support positioning block 52, the support gasket 51 and the slot 31 in sequence from above.

[0042] In addition, the support positioning block 52 includes a middle support positioning block 521 for supporting the middle position of the bottom of the part and two side support positioning blocks 522 for supporting both sides of the bottom of the part. The middle support positioning block 521 and the two side support positioning blocks 522 of this embodiment can be installed and fixed in different slots 31 of the bottom positioning slot 31 plate 3 through fixing pins 53, and can be adjusted horizontally left and right to achieve flexible positioning needs.

[0043] In detail, the middle supporting and positioning block 521 is provided with a first inclined surface 5211 and a second inclined surface 5212 extending outwardly on opposite sides, and the first inclined surface 5211 and the second inclined surface 5212 can prevent the battery tray from sliding out from the bottom or bouncing and detaching from the middle supporting and positioning block 521 during transportation; three sides of the supporting and positioning blocks 522 on both sides are provided with a third inclined surface 5221, a fourth inclined surface 5222 and a fifth inclined surface 5223 extending outwardly, and the third inclined surface 5221 and the fourth inclined surface 5222 are on opposite sides, and the fifth inclined surface 5223 is adjacent to the third inclined surface 5221 and the fourth inclined surface 5222 at the same time, and there is a gap between the third inclined surface 5221 and the fourth inclined surface 5222, and the fifth inclined surface 5223 can provide lateral positioning of the battery tray to prevent lateral sliding out or bouncing and detaching from the supporting and positioning blocks 522 on both sides, and the fifth inclined surface 5223 can also be used as an auxiliary guiding structure when placing the battery tray.

[0044] Because the edges of some battery trays may have different shapes, or even have higher and longer protrusions, these protrusions cannot be placed directly on the support positioning blocks 52. If placed directly, deformation may occur. Therefore, the support positioning blocks 52 need to avoid the protrusions, so that adjacent support positioning blocks 52 need to be preset at a certain distance, and the lengths of the support positioning blocks 522 on both sides and the middle support positioning block 521 are shorter, ensuring that there is enough space between the support positioning blocks 52 to prevent interference with the battery tray, thereby further increasing versatility and flexibility of use.

[0045] The support pads 51 of this embodiment include several pieces. According to the different height requirements of the support points of the battery tray, the height of the support positioning blocks 522 on both sides and the middle support positioning block 521 can be achieved by increasing or decreasing the support pads 51. The support pads 51 can be selected with different thicknesses / numbers according to the actual situation, corresponding to parts of different sizes and heights, and can be used flexibly. In addition, if a robot gripper is used to grab the battery tray, after the battery tray is raised by the support pads 51, an empty space is formed, which facilitates the gripper to loosen at the bottom and detach from the battery tray.

[0046] Through this implementation, a battery tray loading trolley is obtained which is highly versatile, safe, practical, easy to use, and easy to repair and maintain. If the trolley needs to be adjusted or the loading battery tray needs to be switched later, the switching and adjustment operation can be simple and low-cost.

In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0048] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
