DETAILED DESCRIPTION

[0024] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0025] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] Unless otherwise specified, the exemplary embodiments / embodiments shown will be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of the various embodiments / embodiments can be combined, separated, interchanged and / or rearranged without departing from the technical concept of the present disclosure.

[0027] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

[0028] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0029] For descriptive purposes, the present disclosure may use spatially relative terms such as "below," "beneath," "below," "above," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, components described as "below" or "beneath" other components or features would then be positioned "above" the other components or features. Thus, the exemplary term "below" can encompass both the "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and as such, the spatially relative descriptors used herein should be interpreted accordingly.

[0030] The terms used here are for the purpose of describing specific embodiments, and are not intended to be restrictive. As used here, unless the context clearly indicates otherwise, the singular forms "one (kind, person)" and "said (the)" are also intended to include plural forms. In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, it is explained that there are stated features, integral bodies, steps, operations, parts, assemblies and / or their groups, but it is not excluded that there are or add one or more other features, integral bodies, steps, operations, parts, assemblies and / or their groups. It should also be noted that, as used here, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values ​​and / or provided values ​​that will be recognized by those of ordinary skill in the art.

[0031] like Figure 1-5 As shown, the scooter battery pack housing of the present disclosure may include: a housing mechanism and a heat dissipation mechanism;

[0032] like Figure 1-5 As shown, the housing mechanism includes an upper shell 1, a lower shell 2, a positioning cylinder 7, a positioning member 8, a fixing seat 9, a cavity 10, a limiting plate 11, a card slot 12, a spring 13, a plug-in 14, a center slot 15, a rotating rod 16, a pull rope 17, a knob 18, a card 19, and a slot 20;

[0033] The lower shell 2 is arranged directly below the upper shell 1, and multiple positioning cylinders 7 are evenly arranged on the inner bottom surface of the lower shell 2. Each positioning member 8 is installed on the lower surface of the upper shell 1 and is directly above the corresponding positioning cylinder 7. The two fixing seats 9 are correspondingly installed on the two inner walls of the lower shell 2. Each group of two slots 12 is opened on the upper surface of the corresponding fixing seat 9. Each cavity 10 is opened inside the corresponding fixing seat 9 and is on one side of the corresponding slot 12. Each limiting plate 11 is arranged in the corresponding cavity 10. Each spring 13 is arranged in the corresponding cavity 10 and is on one side of the limiting plate 11. The plug-in 14 is installed at the center of the side of the corresponding limiting plate 11 and extends into the adjacent card slot 12. Each of the central slots 15 is opened at the inner center of the corresponding fixing seat 9. Each of the rotating rods 16 is rotatably installed in the corresponding central slot 15. Each of the pull ropes 17 is installed at the center of the other side of the corresponding limiting plate 11 and the end thereof extends into the central slot 15 and is fixedly connected to the rotating rod 16. Each of the knobs 18 is installed at the end of the corresponding rotating rod 16 extending to the outside. The four card members 19 are installed in a rectangular shape on the lower surface of the upper shell 1, and each of the slots 20 is opened on the side of the corresponding card member 19.

[0034] When the shell mechanism needs to be opened, the two knobs 18 are rotated in the same direction to drive the two rotating rods 16 to rotate in the same direction and wrap around the four pull ropes 17, thereby pulling the four limit plates 11 to move. Each moving limit plate 11 compresses the spring 13 and also drives the plug-in 14 to move out of the slot 20 and into the cavity 10, so that the fixation of the clamp 19 can be released, and then the upper shell 1 and the lower shell 2 can be separated;

[0035] When installing the shell, rotate the two knobs 18 in the same direction to allow each plug-in 14 to enter the cavity 10 through the above operation, and then insert the four clips 19 of the upper shell 1 into the four slots 12. When fully inserted, the upper shell 1 is just closed with the lower shell 2. At the same time, each positioning member 8 on the upper shell 1 is inserted into the corresponding positioning cylinder 7 on the lower shell 2, and the slot 20 on each clip 19 is aligned with the corresponding plug-in 14. Then release the two knobs 18 to allow all the springs 13 to rebound and drive the limit plate 11 to restore its position, thereby driving each plug-in 14 to be inserted into the aligned slot 20, and the installation of the upper shell 1 and the lower shell 2 is completed.

[0036] like Figure 1-5 As shown, the heat dissipation mechanism includes a graphite plate 3, an outer metal plate 4, heat dissipation fins 5, and a graphite connector 6;

[0037] The graphite plate 3 is mounted on the lower surface of the upper shell 1, the outer metal plate 4 is mounted on the upper surface of the upper shell 1, a plurality of the heat dissipation fins 5 are evenly mounted on the upper surface of the outer metal plate 4, and a plurality of the graphite connectors 6 are mounted on the upper surface of the graphite plate 3 and penetrate the upper shell 1 and are fixedly connected to the outer metal plate 4;

[0038] Heat is generated when the battery pack is charged and discharged. Since the graphite plate 3 and the graphite connector 6 have high thermal conductivity, the heat generated by the battery charging and discharging is transferred to the outer metal plate 4 through the graphite plate 3 and the graphite connector 6, and finally evenly distributed on each heat dissipation fin 5, and finally dissipated to the outside, thereby playing a heat dissipation role for the battery pack;

[0039] In the description of this specification, the description with reference to the terms "one embodiment / method", "some embodiments / methods", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment / method or example are included in at least one embodiment / method or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment / method or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments / methods or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments / methods or examples described in this specification and the features of different embodiments / methods or examples, unless they are contradictory.

[0040] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
