The battery cover 300 is arranged on the compartment opening of the battery compartment 140. The battery cover 300 is clamped with the side wall of the battery compartment 140.

[0035] When the battery assembly 200 needs to be replaced, the battery cover 300 is only needed to be opened, and a new battery assembly 200 is loaded into the battery compartment 140. The battery assembly 200 is replaced by clamping the battery cover 300 with the side wall of the battery compartment 140.

[0036] The ETC vehicle-mounted unit provided by the embodiment of the present application is electrically connected with the vehicle-mounted main body 100 through the battery assembly 200, so that the vehicle-mounted main body 100 can be powered by the battery assembly 200. The battery assembly 200 does not occupy the electrical interface and wiring space in the vehicle, and the power supply stability is not affected by the weather, thereby ensuring the power supply stability of the ETC vehicle-mounted unit. Meanwhile, the battery cover 300 is clamped with the side wall of the battery compartment 140, which not only ensures the assembly stability of the battery assembly 200, but also facilitates the replacement of the battery assembly 200, thereby ensuring the power supply continuity of the ETC vehicle-mounted unit.

[0037] In some embodiments, the battery assembly 200 and the battery cover 300 are detachably connected. The battery assembly 200 and the battery cover 300 are connected, so that the battery assembly 200 and the battery cover 300 can be integrally disassembled. That is, when the battery cover 300 is detached from the vehicle-mounted main body 100, the battery assembly 200 can be disassembled, thereby realizing the quick disassembly of the battery assembly 200. In addition, the battery cover 300 and the battery assembly 200 are detachable, so that the battery assembly 200 or the battery cover 300 can be replaced individually. The battery assembly 200 and the battery cover 300 do not need to be replaced as a whole when the battery assembly 200 is damaged, thereby saving costs.

[0038] In some embodiments, the battery assembly 200 and the battery cover 300 are detachably connected by the first fastener locking manner, which not only can connect the battery assembly 200 and the battery cover 300 firmly, but also is convenient for disassembly. It can be understood that in other embodiments of the present application, the battery assembly 200 and the battery cover 300 can also be detachably connected by the buckle connection manner, or can also be detachably connected by the interference insertion or the pin connection manner.

Taking the arc-shaped protrusion as an example, during assembly, the elastic portion 320 can be inserted into the battery compartment 140, and the arc-shaped protrusion slides along the inner wall of the battery compartment 140. The elastic portion 320 is deformed due to the extrusion of the arc-shaped protrusion and the inner wall of the battery compartment 140, until the arc-shaped protrusion slides into the arc-shaped groove, and the elastic portion 320 is elastically abutted to the inner wall of the battery compartment 140. In this embodiment, through the setting of the elastic portion 320, the arc-shaped protrusion can be easily clamped into the arc-shaped groove, and the clamping of the arc-shaped protrusion and the arc-shaped groove can be ensured to be firm. In addition, it can effectively buffer the buffer vibration energy of the vehicle body 100, and ensure the connection stability of the battery cover 300 and the vehicle body 100. It can be understood that in other embodiments of the present application, an elastic arm can also be arranged on the inner wall of the battery compartment 140 corresponding to the vehicle body 100, and then the second clamping portion 1121 is formed on the elastic arm, and the elastic clamping of the first clamping portion 330 and the second clamping portion 1121 can also be realized.

The inner wall of the battery compartment 140 is provided with a second clamping portion 1121 corresponding to the position of each first clamping portion 330. Each first clamping portion 330 is correspondingly clamped with each second clamping portion 1121. In this embodiment, the first clamping portion 330 is arranged corresponding to each battery 220, and the first clamping portion 330 is arranged corresponding to the opposite sides of the battery 220 in the first direction X, thereby ensuring the clamping stability of the battery cover 300 and the battery assembly 200 with the vehicle body 100.

[0047] In some specific embodiments, referring to Figure 3 and Figure 4 , the battery cover 300 includes a cover plate 310 and two sets of elastic portions 320, which are arranged on the inner side of the cover plate 310 in the first direction X. Each set of elastic portions 320 includes two elastic portions 320 arranged in the second direction Y. The two elastic portions 320 of each set of elastic portions 320 are spaced apart to form a slot 340. During assembly, one end of the battery plate 210 facing the cover plate 310 is inserted into the slot 340 of each set of elastic portions 320, and the elastic portion 320 and the battery cover 300 are locked by the first fastener, thereby forming the connection between the battery cover 300 and the battery assembly 200. The two slots 340 can realize the assembly positioning of the battery plate 210 and the battery cover 300. In addition, the two elastic portions 320 are clamped and locked on opposite sides of the battery plate 210, which can ensure the connection reliability of the battery cover 300 and the battery plate 210.

[0048] Specifically, referring to Figure 3 and Figure 4 , the elastic portion 320 includes a base plate 321 arranged vertically on the cover plate 310. The base plate 321 has a first mounting hole, and the battery plate 210 has a second mounting hole.
