[0002] With the continuous popularization of new energy technologies, the application of lithium batteries is becoming more and more extensive. In the field of motorcycle starting batteries, it is becoming more and more common to replace lead-acid batteries with lithium batteries. The volume of lead-acid batteries is usually larger than that of lithium batteries. The space originally used for lead-acid batteries on motorcycles is relatively large. When this space is used to install lithium batteries, the battery installation is unstable. Summary of the Invention

[0003] The utility model aims at the problems existing in the prior art and provides a battery bottom bracket, aiming to overcome the defect that when the existing lithium battery replaces the lead-acid battery, the installation is unstable due to inappropriate dimensions.

Detailed Description of the Embodiment

[0017] The following will further elaborate on the specific implementation manners of the present utility model in conjunction with the accompanying drawings of the embodiments, so that the technical solutions of the present utility model can be more easily understood and grasped. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] This embodiment provides a bottom bracket 200 for a battery 100. As Figures 1-4 shown, the bottom bracket 200 includes an outer frame body 210 and support ribs 220 connected to the inner side of the outer frame body 210. The upper ends of the support ribs 220 are lower than the upper end of the outer frame body 210. The part of the outer frame body 210 that protrudes above the support ribs 220 has clamping ribs 230. The lower end of the outer frame body 210 has a connecting portion 250 that is concave inward relative to the upper end of the outer frame body 210. The outside of the connecting portion 250 has a clamping groove 240 corresponding to the clamping ribs 230. The inner side of the outer frame body 210 has a hollow 221 surrounded by the support ribs 220.

[0019] The lower ends of the battery 100 and the base 200 have the same shape and size and also have a card slot 240. The lower end of the battery 100 is embedded inside the outer frame 210. The card ribs 230 on the outer frame 210 are snapped onto the card slot 240 of the battery 100, so that the first base 200 is directly fixed on the battery 100. If the battery 100 with one base 200 is still not high enough, a second base 200 can be further installed below the first base 200. The lower end of the first base 200 is embedded inside the outer frame 210 of the second base 200, and the corresponding card ribs 230 and card slots 240 are snapped together. In this embodiment, the thickness of the base 200 is 10 mm.

[0020] As Figure 3 , 4 shown, the outer frame 210 is square. The outer frame 210 includes a long side and a wide side, and card ribs 230 are provided on both the long side and the wide side. In this way, the fixation of the base 200 is more stable.

[0021] As Figure 3 , 4 shown, upwardly penetrating first grooves 211 are provided at both ends of the long side. The distance between the two first grooves 211 is greater than the length of the card ribs 230 on the long side. The long side at the position of the first grooves 211 is thinner and is prone to deformation, which is conducive to the card ribs 230 being snapped into the card slot 240.

[0022] As Figure 3 , 4 shown, the wide side has a plurality of second grooves 212 penetrating up and down. The distance between the two furthest second grooves 212 is greater than the length of the card ribs 230 on the wide side. Similarly, the wide side at the position of the second grooves 212 is thinner and is prone to deformation, which is conducive to the card ribs 230 being snapped into the card slot 240.

[0023] As Figure 3 , 4 shown, some of the hollowings 221 penetrate up and down. The fact that the hollowings 221 penetrate can greatly reduce the material used for the base 200 and improve the heat dissipation efficiency during the operation of the battery. Some of the hollowings 221 have closing rib plates 222. In other alternative embodiments, an elastic pad can be placed on the rib plate 222, and the elastic pad can also support the bottom of the battery 100 or the corresponding rib plate 222 of the upper base 200 above, avoiding the shaking of the base 200 and making the fixation of the base 200 more stable. In other alternative embodiments, all the hollowings can also be through holes.

[0024] As Figure 3As shown, the middle part of the long side has a rib 230, and a reinforcing rib 260 is provided between the middle area of the long side and the support rib 220. The upper end of the reinforcing rib 260 is lower than the upper end of the support rib 220. When ensuring the strength of the outer frame 210, the upper end of the reinforcing rib 260 is relatively low, which facilitates appropriate deformation at the position where the rib 230 is located and facilitates the disassembly and assembly of the bottom tray 200.
