[0018] As a refinement of the above embodiment, the slide rail bracket includes a first slide rail bracket 205 and a second slide rail bracket 206 which are cross-rotatably connected in the middle. The push rod linkage assembly 100 drives the cross movement of the first slide rail bracket 205 and the second slide rail bracket 206 to change the height of the cross bar 204. When the cross bar 204 is lifted to the molded case circuit breaker 2, it continues to lift and drives the switch handle of the molded case circuit breaker 2 to the closed state.
[0019] The charging pile body 3 is the main structure of the charging pile, which is used to accommodate and protect the various components inside the charging pile. Its design is strong and durable, and can resist the erosion of the external environment to ensure the normal operation of the charging pile.
[0020] The molded case circuit breaker 2 is an important component of the charging pile, which is used to control the power on and off of the charging pile. It is installed in the charging pile body 3, and the power is turned on and off by the operation of the closing component.
[0021] The closing assembly is the core component of the present invention, and is used to realize the electric closing operation of the molded case circuit breaker. Its structure is complex and delicate, and includes a push rod linkage assembly, a connecting rod bracket, a cross bar, a slide rail bracket, a slider, and a slide rail.
[0022] The connecting rod bracket adopts the design of the first slide rail bracket 205 and the second slide rail bracket 206 which are cross-rotatably connected in the middle. This design enables the connecting rod bracket to more flexibly adapt to the up and down movement of the cross bar during movement, thereby ensuring the accuracy and stability of the closing operation.
[0023] The slide rail bracket 201 is fixed to the inner wall of the charging pile body 3, and is used to support and fix the slide rail 203. The slide rail 203 is arranged on the inner side of the slide rail bracket 201, and is slidably connected with the sliders 202 at both ends of the cross bar 204.

[0026] The push rod linkage assembly 100 is the power source and transmission component of the closing assembly. The telescopic action of the electric push rod 101 drives the movement of the entire push rod linkage assembly, and the slide rail base is used to support and fix the electric push rod and subsequent telescopic assemblies.
[0027] As a refinement of the above embodiment, the telescopic assembly includes a left slider 103, a left connecting rod 104, a rotating rod 105, a right connecting rod 106, and a right slider 107 connected in sequence.
