DETAILED DESCRIPTION

[0020] The present application will be further described in detail below with reference to the accompanying drawings and examples.

[0021] like Figures 1 to 4As shown, this embodiment discloses a battery module support assembly, including a first plate 1 and a second plate 2, the first plate 1 and the second plate 2 being correspondingly arranged to form a cavity for accommodating a battery cell 3, the first plate 1 including a first side plate 11 and a first end plate 12 located at both ends of the first side plate 11, the second plate 2 including a second side plate 21 and a second end plate 22 located at both ends of the second side plate 21, the first end plate 12 being connected to the first side plate 11 at an angle, the second end plate 22 being connected to the second side plate 21 at an angle, and the first end plate 12 and the second end plate 22 being detachably connected. The first end plate 12 cooperates with the second end plate 22, the first plate 1 and the second plate 2 are assembled to form a cavity for accommodating a battery cell 3, the first end plate 12 and the second end plate 22 are separated, and the first plate 1 and the second plate 2 can be separated, thereby realizing the modularization of the battery module support assembly and facilitating processing and transportation.

[0022] like Figure 1 As shown, the first end plate 12 is provided with a first connecting plate 4, and the second end plate 22 is provided with a second connecting plate 5. The first connecting plate 4 is provided with a first slot 6 on the side facing the second connecting plate 5, and the second connecting plate 5 is provided with a first block assembly 7 that cooperates with the first slot 6 on the side facing the first connecting plate 4. The first plate 1 and the second plate 2 are detachably connected through the cooperation of the first slot 6 and the first block assembly 7.

[0023] like Figure 2As shown, the width of the opening of the first card slot 6 is smaller than the width of the bottom of the card slot, and the first clamping block assembly 7 includes a first clamping member 71 and a second clamping member 72. There is a gap between the first clamping member 71 and the second clamping member 72. One end of the first clamping member 71 and one end of the second clamping member 72 are respectively connected to the second connecting plate 5. A first clamping protrusion 73 is provided on the side of the other end of the first clamping member 71 facing away from the second clamping member 72, and a second clamping protrusion 74 is provided on the side of the other end of the second clamping member 72 facing away from the first clamping member 71. The first clamping protrusion 73 and the second clamping protrusion 74 are respectively engaged with the first card slot 6. The diameter of the first clamping protrusion 73 gradually increases from the end away from the second connecting plate 5 to the end close to the second connecting plate 5, and the diameter of the second clamping protrusion 74 gradually increases from the end away from the second connecting plate 5 to the end close to the second connecting plate 5. The first and second latching protrusions 73, 74 are tapered. When the first and second plates 1 and 2 need to mate, the smaller ends of the first and second latching protrusions 73, 74 first enter the first slot 6. As they enter, the first and second latching members 71, 72 approach each other, allowing the first and second latching protrusions 73, 74 to smoothly enter the first slot 6. The first and second plates 1 and 2 are also made of plastic and have a certain degree of elasticity. The first latching member 71 has a first notch 75 on the end closest to the second connecting plate 5, and the second latching member 72 has a second notch 76 on the end closest to the second connecting plate 5. The first and second notches 75, 76 respectively reduce the width of the first and second latching members 71, 72, thereby increasing their flexibility and the elasticity of the first and second plates 1 and 2.

The first end panel 12 and the first limiting plate 13 are respectively arranged at an angle to the first side panel 11, and the second end panel 22 and the second limiting plate 23 are respectively arranged at an angle to the second side panel 21. The first limiting plate 13 and the second limiting plate 23 are respectively arranged in correspondence with each other. The number of first limiting plates 13 and second limiting plates 23 can be multiple. For example, if the number of first limiting plates 13 and second limiting plates 23 is N, then the number of first cavities for accommodating three groups of battery cells is N+1. In this embodiment, the number of first limiting plates 13 and second limiting plates 23 is one, and the number of first cavities is two.

[0025] like Figure 3 As shown, the first end plate 12, the first side plate 11, and the first limiting plate 13 form a first receiving groove 14 for accommodating the battery cell 3, and the second end plate 22, the second side plate 21, and the second limiting plate 23 form a second receiving groove 24 for accommodating the battery cell 3. The first receiving groove 14 and the second receiving groove 24 are correspondingly arranged to form the said cavity.

[0026] like Figure 4 As shown, the end of the first connecting plate 4 is provided with a second card slot 8, and the second connecting plate 5 is provided with a second card block assembly 9 that cooperates with the second card slot 8. The number of battery module support assemblies can be multiple. When the first plate 1 and the second plate 2 are matched, the second card block assembly 9 of one battery module support assembly cooperates with the second card slot 8 of the other battery module support assembly to achieve the matching connection of the two battery module support assemblies, and then the assembled battery module support assemblies are uniformly placed inside the chassis. The structure of the first card slot 6 refers to the first card slot 6, and the structure of the second card block assembly 9 refers to the first card block assembly 7. The first plate 1 and the second plate 2 are respectively made of plastic. Plastic material can effectively reduce the risk of short circuit, is light in weight, and is easy to install and maintain. The side of the first limiting plate 13 facing away from the second limiting plate 23 and the side of the second limiting plate 23 facing away from the first limiting plate 13 are respectively provided with a limiting groove 131 for cooperating with the chassis. A limiting protrusion is provided inside the chassis, and the chassis limits the plastic shell through the cooperation between the limiting protrusion and the limiting groove 131 to prevent the plastic shell from shifting.
