[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0035] Please refer to the following Figures 1 to 8 A battery assembly and a mobility scooter having the same according to an embodiment of the utility model.

[0036] like Figures 1 to 5As shown, the battery assembly of the embodiment of the utility model includes: a battery compartment 1, a battery pack 2, a controller 3 and a plurality of fixing blocks 4. An installation cavity 11 is provided in the battery compartment 1, and the battery pack 2 and the controller 3 are both provided in the installation cavity 11, and the battery pack 2 and the controller 3 are arranged along the front-to-back direction of the installation cavity 11, and the plurality of fixing blocks 4 are arranged at intervals along the circumference of the controller 3, and the controller 3 is connected to the battery compartment 1 through the plurality of fixing blocks 4, and at least some of the fixing blocks 4 are against the battery pack 2.

[0037] It is understandable that the number of the fixing block 4 abutting against the battery pack 2 may be one or more.

[0038] According to the battery assembly of the embodiment of the utility model, when the battery assembly is assembled, the controller 3 can be fixed by multiple fixing blocks 4. Since at least part of the fixing blocks 4 abut against the battery pack 2, the fixing blocks 4 can also limit the battery pack 2. In other words, the battery pack 2 and the controller 3 of the battery assembly of the embodiment of the utility model can share the fixing blocks 4 for installation and positioning, and there is no need to set up additional battery-specific fixings. Therefore, the battery assembly of the embodiment of the utility model can limit the battery, and the structural design is simple, which is conducive to reducing the space occupied in the battery compartment 1.

[0039] like Figure 1 and Figure 8 As shown, a pedal 7 is provided above the battery compartment 1 to cover the mounting cavity 11. The controller 3 can be installed on the front side of the battery pack 2 or on the rear side of the battery pack 2. In the example of the present application, the controller 3 is installed on the rear side of the battery pack 2.

[0040] Alternatively, if Figure 5 and Figure 6 As shown, the fixed block 4 includes a fixed body 41 and an abutment portion 42. The fixed body 41 is connected to the controller 3 and the battery compartment 1. The abutment portion 42 is arranged on the fixed body 41 and extends upward. The abutment portion 42 has an abutment surface, and the abutment surface is in contact with the side wall of the battery pack 2. It can be understood that the abutment portion 42 protrudes upward to increase the abutment area of ​​the abutment surface to ensure the reliability of the abutment between the fixed block 4 and the battery pack 2. The abutment surface is in contact with the side wall of the battery pack 2, and the front and rear directions of the battery pack 2 can be limited. In other words, the fixed block 4 can limit the problem of the battery pack 2 shaking along the front and rear directions of the battery compartment 1.

[0041] In one example, if Figure 2 and Figure 5As shown, the controller 3 has an edge portion 31, and the fixed block 4 is arranged between the edge portion 31 and the bottom wall of the battery compartment 1. The battery assembly also includes a first fastener 51 and a second fastener 52. The first fastener 51 is penetrated through the fixed block 4 and the bottom wall of the battery compartment 1, and the second fastener 52 is penetrated through the edge portion 31 and the fixed block 4. When assembling the fixed block 4 and the controller 3, the first fastener 51 can be penetrated through the fixed block 4 and the battery compartment 1 to install the fixed block 4 on the battery compartment 1. Then align the edge portion 31 with the upper end surface of the fixed block 4 and lock it with the second fastener 52. This makes it easy to assemble the controller 3 and the fixed block 4, and the assembled controller 3 and the fixed block 4 are more secure.

[0042] For example, the first fastener 51 and the second fastener 52 may be screws. The first fastener 51 is disposed through the battery compartment 1 and the fixing block 4 from bottom to top, and the second fastener 52 is disposed through the edge portion 31 and the fixing block 4 from top to bottom.

[0043] Alternatively, if Figure 7 As shown, the fixing block 4 has a positioning column 43, and the bottom wall of the battery compartment 1 is provided with a positioning hole, and the positioning column 43 is passed through the positioning hole. It can be understood that when the fixing block 4 is installed on the bottom wall of the battery compartment 1, the positioning column 43 can be inserted into the positioning hole first to install and position the fixing block 4, and then the first fastener 51 can be screwed on the fixing block 4 and the battery compartment 1, thereby improving the assembly efficiency of the fixing block 4.

[0044] For example, there are two positioning posts 43 , and the two positioning posts 43 are arranged on the fixing block 4 at intervals along the left-right direction to improve the positioning accuracy when the fixing block 4 is installed.

[0045] In one example, if Figure 2 and Figure 5 As shown, there are three fixing blocks 4, one fixing block 4 is arranged between the battery pack 2 and the controller 3, and the other two fixing blocks 4 are arranged on the side of the controller 3 away from the battery pack 2. It can be understood that the three fixing blocks 4 are arranged in a triangle to improve the firmness of the installation of the controller 3. On the other hand, since only one fixing block 4 is arranged between the battery pack 2 and the controller 3, other components can be arranged between the battery pack 2 and the controller 3.

[0046] Optionally, the battery assembly further includes a first buffer layer 61, which is located in the installation cavity 11 and is disposed on the side of the battery pack 2 away from the controller 3, and the first buffer layer 61 elastically abuts against the battery compartment 1 and the battery pack 2. It is understandable that the first buffer layer 61 is disposed on the front side of the battery pack 2, and due to the elastic buffering effect of the first buffer layer 61, the problem of hard collision between the battery pack 2 and the battery compartment 1 when the battery pack 2 shakes back and forth can be avoided, so as to improve the stability of the installation of the battery pack 2.

[0047] Furthermore, if Figure 4 As shown, the battery assembly further includes a second buffer layer 62 and a pressure plate (not shown), both of which are arranged in the mounting cavity 11, the pressure plate is arranged at the upper end of the battery pack 2 and abuts against the battery pack 2, and the second buffer layer 62 elastically abuts between the bottom of the battery pack 2 and the battery compartment 1. It can be understood that under the action of the pressure plate and the second buffer layer 62, the battery pack 2 can be restricted from shaking in the up and down directions, and the problem of hard collision between the battery pack 2 and the bottom wall of the battery compartment 1 can be avoided, so as to improve the stability of the installation of the battery pack 2.

[0048] For example, the first buffer layer 61 and the second buffer layer 62 are foams, which can fix the battery pack 2 and provide buffering and shock absorption for the battery pack 2, and are easy to obtain and have low processing costs. For example, the pressing plate is a metal sheet metal part.

[0050] According to the scooter of the embodiment of the present invention, when assembling the battery assembly, the controller 3 can be fixed by a plurality of fixing blocks 4. Since at least part of the fixing blocks 4 abut against the battery pack 2, the fixing blocks 4 can also limit the position of the battery pack 2. In other words, the battery pack 2 and the controller 3 of the scooter of the embodiment of the present invention can share the fixing blocks 4 for installation and positioning, and there is no need to set up additional battery-specific fixings. Therefore, the battery assembly of the scooter of the embodiment of the present invention can limit the battery, and the structural design is simple, which is conducive to reducing the space occupied in the battery compartment 1.
