Detailed implementation manners

[0048] The following description provides many different embodiments or examples for implementing different features of the present invention. The components and arrangements described in the following specific examples are only used to concisely express the present invention, and they are only examples and not intended to limit the present invention.

[0049] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0050] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0051] In the description of the present invention, when it is stated that a certain part is "connected" to other parts, this includes not only the case of direct connection but also the case of indirect connection. Indirect connection includes connection through a wireless communication network.

[0052] In the description of the present invention, when it is stated that a certain component is "above" or "below" other components, this includes not only the case where a certain component is in contact with other components but also the case where there are other components between the two components.

[0053] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0054] In addition, terms such as "first" and "second" are used for descriptive distinction only and should not be construed as indicating or implying relative importance.

[0055] In addition, the "first flanging part", "second flanging part", "third flanging part", etc. in the present invention are all realized through the flanging process in the stamping process.

The fasteners 14 passing through the mounting holes fix the adjacent two bottom plates 7 on the second flanging part 102. Preferably, the fasteners 14 can be rivet bolts and press nuts.

[0079] Regarding the first layout plan of the battery support assembly: For details, please refer to Figure 7 , when it is necessary to install a battery 13 with a model of 105Ah or 120Ah, adjust the distance at the bottom of the battery support and adjust the distance between the adjacent two bottom plates 7 to make the bottom plate 7 move away from its adjacent bottom plate 7, so as to increase the distance therebetween and provide a large installation space for the battery 13 with a model of 105Ah or 120Ah. After the distance between the adjacent two bottom plates 7 is adjusted, implement the connection process. For details, please refer to Figure 9 , align the mounting holes provided at both ends of the bottom plate 7 with the mounting holes arranged at intervals on the second flanging part 102, and by means of bolt connection, make the fasteners 14 pass through the mounting holes arranged at intervals on the second flanging part 102 to fix both ends of the bottom plate 7 on the second flanging part 102.

[0080] Regarding the second layout plan of the battery support assembly: For details, please refer to Figure 8, when it is necessary to install the battery 13 with a model of 80Ah or 90Ah, adjust the distance at the bottom of the battery bracket and the distance between two adjacent bottom plates 7, so that the bottom plate 7 and its adjacent bottom plate 7 approach each other, thereby reducing the distance therebetween, providing a small installation space for the battery 13 with a model of 80Ah or 90Ah. After the distance between two adjacent bottom plates 7 is adjusted, implement the connection process, where the connection process is the same as the first layout scheme above and will not be repeated here.

[0081] When the above battery bracket assembly implements the layout scheme, in order to further achieve the stability and safety of the battery 13 after being installed in the battery bracket assembly, the present invention also provides the following preferred implementation schemes. For details, please refer to Figure 10 :

[0082] As a preferred scheme of the present invention: the bottom plate includes a bottom plate body 703, a second kidney-shaped hole 7032 is provided on the bottom plate body 703, and a buffer pad 701 covering the second kidney-shaped hole 7032 is provided on the bottom plate body 703. Preferably, the buffer pad 701 is rectangular and made of natural rubber, so that the battery 13 installed in the battery bracket assembly can be buffered when being vibrated or jolted, thereby avoiding damage caused by the collision between the battery 13 and the inner wall of the battery bracket assembly. At the same time, the second kidney-shaped hole 7032 provided can further reduce the weight of the bottom plate 7.

[0083] As a preferred scheme of the present invention, a seventh flanging part 704 that turns downward is provided on one side of the bottom plate body 703, an eighth flanging part 705 with a flanging direction opposite to that of the seventh flanging part 704 is provided on the outer edge of the seventh flanging part 704, a fifth flanging part 702 with the same flanging direction as that of the seventh flanging part 704 is provided on the other side of the bottom plate body 703, and sixth flanging parts 7031 that turn upward are provided at both ends of the bottom plate body 703. The two sixth flanging parts 7031 abut against both ends of the buffer pad 701. After the bottom plate 7 is formed by bending, the seventh flanging part 704, the eighth flanging part 705, and the fifth flanging part 702 are formed. These three flangings can play a role in restricting the movement of the battery 13 in the battery bracket assembly, while the sixth flanging part 7031 can play a role in restricting the movement position of the buffer pad 701 on the bottom plate body 703.

[0084] Based on the implementation process of the layout scheme of the battery bracket assembly in the above Embodiment 2, by adjusting the distance between two adjacent bottom plates 7 and the installation position between the installation holes on the second flanging part 102 at the bottom of the battery bracket, the installation of batteries 13 with different specifications and models in the battery bracket assembly can be satisfied. Therefore, it has the advantages of modularization and generalization. At the same time, the battery bracket assembly can also be installed and arranged according to different application scenarios. For the specific implementation process, please refer to the subsequent embodiments.
