Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0035] In order to facilitate subsequent description, before describing the specific structure of the integrated mounting support, the present application first defines the first direction (X), the second direction (Z) and the third direction (Y) in combination with Figure 1 The first direction is the length direction when the integrated mounting support is normally placed, for example, the X direction;The second direction is the height direction when the integrated mounting support is normally placed, for example, the Z direction;The third direction is the width direction when the integrated mounting support is normally placed, for example, the Y direction. The first direction (X), the second direction (Z) and the third direction (Y) are perpendicular to each other in the present application.
[0036] It is understood that the mutual perpendicularity in this application is not absolute perpendicularity. Approximate perpendicularity due to processing errors and assembly errors (e.g., the included angle between two structural features is 89.9°) is also within the scope of mutual perpendicularity in this application.
[0037] See Figures 1 to 3 As shown, Figure 1 This application provides a schematic diagram of the assembly structure of an embodiment of an integrated mounting bracket. Figure 2 A three-dimensional structural schematic diagram of an embodiment of an integrated mounting bracket provided in this application is shown. Figure 1 ; Figure 3 A schematic diagram of the internal structure of an embodiment of an integrated mounting bracket provided in this application is shown.
[0038] In some embodiments, the integrated mounting bracket for the battery box includes a first fixing part 10, a second fixing part 20, and a connecting part 40. The first fixing part 10 has a charging hole 11 extending through it along a first direction; the second fixing part 20 is spaced apart from the first fixing part 10 along the first direction, wherein the second fixing part 20 includes a first lock chamber 21 and a second lock chamber 22 that are interconnected, the first lock chamber 21 is used to accommodate a lock cylinder 210, and the second lock chamber 22 is used to accommodate a lock tongue 220 corresponding to the lock cylinder 210.
[0039] The connecting part 40 is connected to the first fixing part 10 and the second fixing part 20 respectively, and together with the first fixing part 10 and the second fixing part 20, they form a wiring chamber 41 for threading wire harnesses.
[0040] In this embodiment, by integrating the first fixing part 10 and the second fixing part 20, the number of components required to achieve the charging and anti-theft functions of the electric bicycle is reduced, and the installation steps and processing difficulty of the battery box are also reduced.

For example, the charging hole 11 can also be fitted with a protective cover to prevent moisture and dust from entering the charging hole 11.
[0041] Combination Figure 3 As shown, the lock cylinder 210 and lock tongue 220 housed in the second fixing part 20 can form a mechanical lock to ensure the anti-theft function of the battery box. The first fixing part 10 and the second fixing part 20 are spaced apart along the first direction. In some application scenarios, the charging port and the lock port can be distributed on both sides of the electric bicycle to improve the space utilization. Integrating the charging function and the anti-theft function into the same bracket can also improve the user's operation convenience and maintenance convenience.
[0042] In addition, the connecting portion 40 is connected with the first fixing portion 10 and the second fixing portion 20 respectively, which improves the stability of the overall bracket, forms a wiring chamber 41 capable of passing through the wiring harness, and facilitates the arrangement and fixation of the wiring harness, so that the battery box is more tidy. Exemplarily, in combination with Figure 2 As shown in the drawings, the connecting portion 40 is provided with a step at the wiring chamber 41, which can facilitate the constraint of the electrical components and the wiring harness located in the wiring chamber 41.
[0043] In some embodiments, the integrated mounting bracket further comprises a third fixing portion 30 connected with the first fixing portion 10 and the second fixing portion 20 respectively, and the third fixing portion 30 is used for obliquely fixing a vehicle tail lamp 31 in a second direction, wherein a wiring harness interface 310 of the vehicle tail lamp 31 extends to the wiring chamber 41.

Figure 4 and Figure 5 As shown in FIG. 3, the third fixing part 30 is provided with a groove 33 at the top along the second direction, and a limiting part 34 extending along the second direction is embedded in the groove 33. Figure 4 As shown in the shadow part of FIG. 3, the limiting part 34 is connected with a limiting seat 50. Since the third fixing part 30 is inclined, the additional limiting part 34 connected with the limiting seat 50 can provide an additional stable fulcrum for the mounting bracket.
[0050] In some embodiments, the mounting bracket is integrated with the battery box. Figure 5 As shown in FIG. 4, the mounting bracket is further provided with a first connecting part 35, and the battery box end cover 60 is provided with a second connecting part 62 capable of concave-convex matching with the first connecting part 35, so that the top and bottom of the battery box end cover 60 are connected with the mounting bracket, ensuring the connection stability of the battery box end cover 60. For example, the battery box end cover 60 and the mounting bracket are further respectively provided with a convex part and a concave part capable of concave-convex matching, so that the battery end cover is positioned through the concave part when the battery box end cover 60 is assembled.
