[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0031] A tray for a battery device, a battery device and an electrical device according to the present invention are described in detail below.

[0032] In one embodiment of the present disclosure, Figures 1-4 The present disclosure provides a tray 1 for a battery device, comprising a bottom plate and a side panel 18, wherein the bottom plate and the side panel 18 are used to form a receiving cavity for receiving a battery cell module, and a bottom guard plate 16 and a maintenance plate 15 are provided on the side of the bottom plate away from the receiving cavity, and a first support beam 13 is provided in the receiving cavity, wherein the first support beam 13 divides the receiving cavity into a first receiving cavity 11 and a second receiving cavity 12, wherein the first receiving cavity 11 is used to install a power distribution module, and the second receiving cavity 12 is used to install the battery cell module; an opening is provided at the bottom of the first receiving cavity 11, and the maintenance plate 15 is detachably covered on the opening. Specifically, Figures 1-4 The power distribution module in the battery device is located in the first accommodating chamber 11. Therefore, when repairing the power distribution module, it is only necessary to remove the maintenance plate 15, and it is not necessary to remove the bottom guard plate 16, which greatly improves efficiency. Specifically, the power distribution module can be a battery management system and related circuits.

[0033] In some embodiments, Figures 1-4 , the bottom guard plate 16 and the adjacent end portions of the maintenance plate 15 overlap. Specifically, Figures 1-4 The end of the bottom guard plate 16 close to the second accommodating cavity 12 and the end of the maintenance plate 15 close to the first accommodating cavity 11 partially overlap. Specifically, the overlapping manner can be that the bottom guard plate 16 is partially located on the maintenance plate 15.

[0034] In some embodiments, Figures 1-4 The bottom guard plate 16 is provided with an overlapping edge 161 at its end, and the maintenance plate 15 is provided with a stepped edge 151 at its end. The overlapping edge 161 is used to cover the stepped edge 151 on the side facing away from the tray 1. Specifically, Figures 1-4, the side of the overlapping edge 161 facing away from the tray 1 is used to cover the stepped edge 151. Specifically, this covering method can be that the stepped edge 151 covers above the overlapping edge 161.

[0035] In some embodiments, such as Figures 1-4 , overlapping area bolt holes 153 are spacedly arranged on both the stepped edge 151 and the overlapping edge 161. The overlapping area bolt holes 153 are adapted to cooperate with overlapping area bolt fasteners to fasten the bottom guard plate 16 and the repair plate 15 to the first support beam 13. Specifically, as Figures 1-4 , the stepped edge 151 covers the overlapping edge 161, and the stepped edge 151 and the overlapping edge 161 are both spacedly and correspondingly provided with overlapping area bolt holes 153. Suitable overlapping area bolt fasteners can be used to fix both the bottom guard plate 16 and the repair plate 15 on the first support beam 13, increasing the structural stability of the tray 1. Specifically, the material of the overlapping area bolt fasteners can be materials such as steel.

[0036] In some embodiments, such as Figures 1-4, on the repair board 15 and the bottom guard board 16, in the areas covering the side wall board 18, first mounting bolt holes 152 and second mounting bolt holes 162 are respectively arranged at intervals. The first mounting bolt holes 152 and the second mounting bolt holes 162 are adapted to cooperate with mounting bolt fasteners to fasten the bottom guard board 16 and the repair board 15 to the side wall board 18. Specifically, the way of arranging at intervals can be uniform interval arrangement or non-uniform interval arrangement. At the same time, second mounting bolt holes 153 and first mounting bolt holes 162 are arranged on the bottom guard board 16 and the repair board 15, and corresponding mounting bolt holes are also arranged on the corresponding contacting side wall board 18, and then installed with mounting bolt fasteners. Specifically, the material of the mounting bolt fasteners can be materials such as steel, and this is done to increase the overall structural stability of the tray 1. Specifically, in this embodiment, the bottom guard board 16 can be of a rectangular structure. The overlapping edge 161 is a side edge of the bottom guard board 16. The overlapping edge 161 is covered by the stepped edge 151. An overlapping area bolt hole 153 adapted to the stepped edge 151 is opened at the overlapping edge 161. During installation, first install the other three sides of the bottom guard board 16, then align the repair board 15 with the bottom surface of the mounting tray 1, install the bolts on the other sides of the repair board 15, and finally install the bolts in the overlapping area of the stepped edge 151 and the overlapping edge 161. The overlapping step design of the overlapping edge 161 and the stepped edge 151 is a structural simplification. One set of bolts for the repair board 15 is less drilled on the tray 1, saving manpower and material resources and facilitating maintenance; the overlapping edge 161 is covered by the stepped edge 151, which can also prevent the overlapping edge 161 from warping and strengthen the structure. For the bottom guard board 16, the existence of the bolts at this place can prevent the bottom guard board 16 from bulging and has a certain guarantee effect on the fixing of the repair board 15, anti-loosening, and anti-sealing failure; when the repair board 15 is removed, since the other three directions of the bottom guard board 16 are bolt-fixed, the removal of the common bolts will not change the position of the bottom guard board 16.

[0037] In some embodiments, such as Figures 1-4 , the depth of the stepped edge 151 from the repair board 15 body along the height direction of the tray 1 is equal to the thickness of the overlapping edge 161 along the height direction of the tray 1. Specifically, it is to make the bottom of the tray 1 flat, facilitating the installation and actual use of the battery device. Specifically, for the design of the stepped edge 151, the depth dimension and the overlapping area size at this place can be appropriately adjusted according to the thickness dimension of the bottom guard board 16 and the design of the bottom guard board 16, that is, as long as the design and development requirements are met, ensuring the tight wrapping effect, which is more beneficial to the fixing of the repair board 15, anti-loosening, and anti-sealing failure.

[0038] In some embodiments, such as Figures 1-4, the repair board 15 adopts a composite reinforced board structure. Specifically, the thickness of the repair board 15 and the strength requirements to be met need to be determined according to the actual situation. When necessary, a composite reinforced board can be used for design to ensure the structural strength and practicality. Specifically, the composite reinforced board can refer to covering one metal plate with another metal plate to achieve the effect of saving resources and reducing costs without reducing the usage effects (such as anti-corrosion performance, mechanical strength, etc.). Specifically, the composite methods usually include explosive cladding method, explosive rolling cladding, rolling cladding, etc.

[0039] In some embodiments, such as Figures 1-4 , the support beam extends along the width direction of the tray 1, the support beam is connected to the bottom plate, and both ends of the support beam are respectively connected to the side wall plate 18. Specifically, this is done to improve the integrity and structural stability of the tray 1.

[0040] In some embodiments, such as Figures 1-4 , on one side of the bottom protection plate 16 facing the second accommodation cavity 12, at least one strengthening portion 163 protrudes, the strengthening portion 163 extends along the width direction of the tray 1, and both ends of the strengthening portion 163 are respectively connected to the side wall plate 18. Specifically, on the one hand, the strengthening portion 163 increases the structural strength of the bottom protection plate 16, and at the same time increases the connection strength between the bottom protection plate 16 and the side wall plate 18.

[0041] In some embodiments, such as Figures 1-4 , the tray 1 further includes a sealing gasket 17, the sealing gasket 17 is arranged at the edge of the opening, and the repair board 15 fits against the sealing gasket to seal the opening. Specifically, the sealing gasket 17 is used to increase the tightness and structural stability of the tray 1. Specifically, the sealing gasket 17 includes but is not limited to foam, which can ensure the sealing between the repair board 15 and the accommodation cavity.

[0042] In some embodiments, such as Figures 1-4 , a battery device is provided, including: the above-mentioned tray 1; the tray 1 further includes a second support beam 14, the second support beam 14 divides the second accommodation cavity 12 into multiple sub-accommodation cavities; multiple battery cell modules, the battery cell modules are formed by stacking multiple single battery cells in the sub-accommodation cavities; a power distribution module, the power distribution module is arranged in the first accommodation cavity 11; an upper cover, the upper cover covers the opening of the accommodation cavity. Specifically, the battery device can be a battery assembly or a battery pack.

[0043] In some embodiments, such as Figures 1-4, provided is an electrical device, characterized by comprising: the above-mentioned tray 1, or, the above-mentioned battery device. Specifically, the battery device is arranged inside the electrical device and is used to provide power for the operation of the electrical device. The battery assembly can be electrical devices such as new energy vehicles and ships.

[0044] In summary, in the present utility model, the bottom guard plate 16 can be first installed on the tray 1, and then the repair plate 15 can be installed; when repairing the distribution box in the bag, only the repair plate 15 needs to be removed for repair, and the bottom guard plate 16 does not need to be removed. The overlapping area between the repair plate 15 and the bottom guard plate 16 adopts a stepped design. The depth of the stepped edge 151 along the height direction of the tray 1 from the body of the repair plate 15 is equal to the thickness of the overlapping edge 161 along the height direction of the tray 1. On the one hand, it can ensure that there is no interference from the bottom guard plate 16 during the removal of the repair plate 15, that is, it has a covering effect on the bottom guard plate 16; on the other hand, it can ensure the reliable and stable fixation of the bottom guard plate 16. At the same time, this covering effect can save the installation holes required for the redesigned bottom guard plate 16 of the tray 1, and the common bolt area can prevent the guard plate from warping, strengthening the structure.
