[0029] 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 clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Combine the following Figure 1-Figure 5 The guide assembly provided in the embodiment of the utility model is described.

[0031] Specifically, the guide assembly includes a support member 101 and a guide member 2 .

[0032] The support member 101 is configured as a groove-shaped structure. For example, the support member 101 is configured as a channel steel or a C-shaped steel. With such a configuration, the support member 101 has low cost and high strength. The support member 101 is used to form the pallet 1, and the notch of the support member 101 is used to face the outside of the pallet 1 so that the platform 8 can extend into the support member 101. That is, the support member 101 is used as a component of the pallet 1, for example, the support members 101 are provided on both sides of the pallet 1, and the support members 101 on both sides face the two sides of the pallet 1 respectively.

[0033] The guide member 2 is arranged inside the support member 101 , that is, the guide member 2 is arranged inside the groove structure. The guide member 2 is used to movably cooperate with the platform 8 , that is, the guide member 2 can move along the platform 8 .

[0034] The guide assembly provided in the embodiment of the utility model forms the pallet 1 by a support member 101 which is set as a groove-shaped structure, and the groove of the support member 101 faces the outside of the pallet 1 for the platform 8 to extend into, and the guide member 2 is arranged inside the support member 101, and is used to movably cooperate with the platform 8. Since the support member 101 is a component of the pallet 1, the guide member 2 is arranged inside the support member 101, which is equivalent to being arranged inside the pallet 1. Compared with the form in which the guide member 2 protrudes from the side wall of the pallet 1 in the related art, arranging the guide member 2 inside the pallet 1 can make full use of the internal space of the pallet 1, so that the overall size of the pallet 1 is smaller and the structure is more compact, which solves the problem of the large size of the pallet 1 and the low space utilization rate.

[0035] In some embodiments provided by the present utility model, the guide assembly further includes a mounting seat 3. The mounting seat 3 is disposed inside the support member 101, and the guide member 2 is mounted on the mounting seat 3. Optionally, the outer wall of the mounting seat 3 is at least partially in contact with the inner wall of the support member 101.

[0036] Since the internal space of the support member 101 is relatively small, it is inconvenient to install and debug the guide member 2. In this embodiment, by providing a mounting seat 3, it is convenient to install and debug the guide member 2 on the mounting seat 3. After debugging, the mounting seat 3 is installed in the support member 101, thereby reducing the difficulty of installing and debugging the guide member 2 and improving the convenience of installing the guide member 2.

[0037] In some embodiments provided by the present invention, the guide member 2 includes a support wheel. The support wheel is rotatably mounted on the mounting seat 3, and the support wheel is used to roll with the platform 8. Specifically, the support wheel is supported on the platform 8, and when the guide assembly moves relative to the platform 8, the support wheel rolls along the platform 8.

[0038] In this embodiment, the rolling cooperation between the support wheel and the platform 8 can reduce the friction between the support wheel and the platform 8, making the relative movement between the guide assembly and the platform 8 smoother, and can reduce the wear of the support wheel and the platform 8, thereby extending the service life of the support wheel and the platform 8.

[0039] In some embodiments provided by the present invention, the mounting base 3 includes a support 301 and a connecting plate 302 .

[0040] The support 301 is configured as a groove-shaped structure. The support 301 is disposed inside the support member 101, and the outer wall of the support 301 and the inner wall of the support member 101 are at least partially in contact with each other, for example Figure 1 As shown, the outer side wall of the support 301 is in contact with the inner side wall of the support member 101, and the outer bottom wall of the support 301 is in contact with the inner bottom wall of the support member 101. The connecting plate 302 is disposed in the notch of the support 301, and the connecting plate 302 is connected to the side wall of the support 301. The supporting wheel is rotatably disposed between the bottom wall of the support 301 and the connecting plate 302.

[0041] In this embodiment, by setting the support 301 as a groove-shaped structure, and the outer wall of the support 301 is in contact with the inner wall of the support member 101, during the movement of the guide assembly relative to the platform 8, the support 301 is subjected to a force which is transmitted to the support member 101. Under the limiting action of the support member 101, the deformation of the support 301 can be reduced, thereby improving the bearing capacity and stability of the support 301.

[0042] Optionally, the support 301 is configured as a profile, or the support 301 is configured as a sheet metal bending plate, or the bottom plate is configured as a forging or casting. Further, the connecting plate 302 can be configured as an integral structure with the support 301, for example, the connecting plate 302 and the support 301 are configured as a bent integral structure, a forged integral structure, or a welded integral structure. Alternatively, the connecting plate 302 can also be connected to the support 301 by screw fixing.

[0043] In some embodiments provided by the present invention, the guide assembly further includes a first threaded connector 5. The mounting seat 3 is detachably connected to the support member 101 via the first threaded connector 5. Such a configuration facilitates the disassembly and assembly of the mounting seat 3. For example, the number of mounting seats 3 in the support member 101 can be increased or decreased according to actual needs on site to balance the weight requirement and the load requirement of the guide assembly.

[0044] Optionally, the first threaded connector 5 passes through the mounting seat 3 and is threadedly connected to the support member 101, for example, the first threaded connector 5 passes through the bottom wall of the support 301 and is threadedly connected to the bottom wall of the support member 101. Alternatively, the first threaded connector 5 passes through the mounting seat 3 and the support member 101 and is threadedly connected to a nut, for example, the first threaded connector 5 passes through the bottom wall of the support 301 and the bottom wall of the support member 101 and is threadedly connected to a nut.

[0045] Furthermore, the first threaded connector 5 is configured as a bolt or a screw, and a countersunk hole is provided on the bottom wall of the base for the head of the first threaded connector 5 to be inserted into, so as to prevent the head of the first threaded connector 5 from protruding from the bottom wall of the base and interfering with the support wheel.

[0046] In some embodiments provided by the present utility model, the guide assembly further comprises a support shaft 4. The support shaft 4 is detachably connected to the mounting seat 3, and the support wheel is rotatably mounted on the support shaft 4.

[0047] In this embodiment, by making the support shaft 4 and the mounting seat 3 detachably connected, when the support shaft 4 or the support wheel is damaged, the support shaft 4 and the support wheel can be conveniently removed and replaced, thereby improving the maintenance convenience of the guide assembly.

[0048] Optionally, the guide assembly further comprises a second threaded connector 6, and the support shaft 4 is configured as a hollow shaft. Figure 1-Figure 2 As shown, the support wheel is rotatably mounted on the support shaft 4, and the support shaft 4 is arranged between the connecting plate 302 and the bottom wall of the support 301, and one end of the support shaft 4 faces the connecting plate 302, and the other end faces the bottom wall of the support 301. The second threaded connector 6 passes through the connecting plate 302 and the support shaft 4 and is threadedly connected to the bottom wall of the support 301 to install and fix the support shaft 4.

[0049] Of course, the support shaft 4 is not limited to being connected to the support 301 through the second threaded connection 6. For example, in other embodiments provided by the present invention, one end of the support shaft 4 is directly threadedly connected to the support seat, and the other end of the support shaft 4 is suspended, and the support wheel is rotatably mounted on the support shaft 4.

[0050] Of course, the guide member 2 is not limited to being in the form of the above-mentioned supporting wheel. For example, in other embodiments provided by the present utility model, the guide member 2 can also be a sliding block.

[0051] refer to Figure 3 As shown, in some embodiments provided by the present invention, at least some of the guide members 2 are arranged in pairs, and any pair of the guide members 2 arranged in pairs are distributed on the upper and lower sides of the platform 8. In this embodiment, by arranging the guide members 2 in pairs, and a pair of guide members 2 are distributed on both sides of the platform 8, when the plane of the tray 1 is uneven or the two sides of the tray 1 are twisted and deformed, at least one guide member 2 in the pair of guide members 2 can keep matching with the platform 8, so that the guide assembly can slide smoothly and lightly along the platform 8.

[0052] Optionally, some of the guide members 2 are arranged in pairs, and the paired guide members 2 are distributed on the upper and lower sides of the platform 8, and another part of the guide members 2 are arranged on the upper side or the lower side of the platform 8. Alternatively, all the guide members 2 are arranged in pairs.

[0053] refer to Figure 4 As shown, in some embodiments provided by the present invention, a plurality of guide members 2 are distributed along the extension direction of the support member 101, and at least two guide members 2 are arranged at at least one end of the support member 101, wherein at least two guide members 2 located at the end of the support member 101 are arranged along the extension direction of the support member 101, and the spacing between at least two guide members 2 located at the end of the support member 101 is smaller than the spacing between the guide members 2 located at other positions of the support member 101.

[0054] Since during the docking process between the pallet 1 and the platform 8, the end of the support member 101 is first docked with the platform 8. In the initial stage of docking, there is less overlap between the support member 101 and the platform 8, which can easily lead to stress concentration and damage of the guide member 2. In this embodiment, by increasing the number of guide members 2 at the ends of the support member 101, at least two guide members 2 can share the stress, thereby reducing the problem of the guide member 2 being damaged due to excessive force.

[0055] The utility model further provides a tray 1 in the embodiment.

[0056] Specifically, the tray 1 includes a connecting beam 102 and the guide assembly as described above. The guide assembly is provided as a pair, and the notches of a pair of support members 101 are respectively facing the two sides of the tray 1, and the pair of support members 101 are connected by the connecting beam 102. For example, the two ends of the connecting beam 102 are respectively welded to the pair of support members 101.

[0057] In this embodiment, the tray 1 includes the guide assembly and also includes all the above advantages of the guide assembly, which will not be elaborated here.

[0058] The embodiment of the utility model further provides a battery cluster 7.

[0059] Specifically, the battery cluster 7 includes the guide assembly as described above or the tray 1 as described above.

[0060] It should be noted that the battery cluster 7 includes the guide assembly or the tray 1, which also includes corresponding advantages, which will not be described in detail here.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
