Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically to a charging pile power module installation structure that is easy to inspect and maintain. Background Technology

[0002] Power modules are a crucial component of electric vehicle charging stations, responsible for the transmission, conversion, and regulation of electrical energy to ensure the stability and safety of the charging process. Power modules are typically designed with a modular structure, facilitating power expansion and redundancy. Multiple power modules can operate in parallel or series to increase the power output of the charging station. Due to their importance and high workload, the long-term stability of power modules directly affects the operating efficiency and lifespan of the charging station.

[0003] In existing charging pile designs, the cabinet structure is used to house all the electronic components inside the charging pile, including power modules, controllers, heat dissipation devices, and other power distribution equipment, resulting in a relatively compact internal space. Power modules are typically installed deep within the cabinet, and may be surrounded and covered by other electronic components, leaving insufficient operating space for maintenance. For maintenance, personnel usually need to remove multiple cabinet panels or external devices, which is time-consuming and prone to causing additional damage. Especially in complex charging pile operating environments, the disassembly and reinstallation process is cumbersome, increasing the risk of equipment failure.

[0004] Therefore, it is necessary to study an installation structure for the power module of a charging pile that is easy to maintain. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a charging pile power module installation structure that is easy to maintain, which can effectively solve the problem that the power modules in existing charging piles are not easy to maintain.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A charging pile power module installation structure that is easy to maintain includes a cabinet, a mounting frame, and a rotating mechanism;

[0008] The cabinet has an electrical compartment, and a front wall covering the electrical compartment is detachably connected to the cabinet.

[0009] The mounting bracket is a cuboid structure, and its interior is used to install power modules;

[0010] A rotating mechanism is installed between the cabinet and the rear end of the left side wall of the mounting frame. The mounting frame is rotated and positioned inside the electrical compartment via the rotating mechanism.

[0011] When the mounting bracket is located inside the electrical compartment, the left side wall of the mounting bracket is spaced apart from the left inner wall of the cabinet to provide clearance for the right end of the mounting bracket to rotate out of the electrical compartment.

[0012] Furthermore, the rotating mechanism includes a rotating shaft, a bushing, and a rotating plate. The rotating shaft is fixed on the frame in the vertical direction, the bushing is rotatably fitted on the rotating shaft, the rotating plate is fixed on the mounting frame, and the bushing is fixedly connected to the rotating plate so that the bushing is indirectly connected to the mounting frame.

[0013] Furthermore, the rotating mechanism is provided in two sets, one above the other. The rotating shaft is L-shaped, including a vertical section extending in the vertical direction and a horizontal section fixedly connected to the vertical section. One end of the rotating shaft is fixedly connected to the top or bottom of the electrical compartment, and the other end is bent and fixedly connected to the inner wall of the electrical compartment. The bushing is rotatably adapted to the vertical section.

[0014] Furthermore, each set of rotating shafts is fitted with two sets of bushings spaced apart vertically, and both sets of bushings are fixedly connected to the rotating plate.

[0015] Furthermore, a partition is horizontally fixed in the electrical compartment, dividing the electrical compartment into two chambers, with the mounting frame located in the upper chamber.

[0016] Furthermore, the bottom of the mounting frame is provided with multiple sets of ball bearing mechanisms spaced apart on the left and right sides, and the bottom of the mounting frame is connected to the upper surface of the partition through the ball bearing mechanisms.

[0017] Furthermore, the ball mechanism includes a ball seat and balls; the lower surface of the ball seat is provided with rolling balls, which roll in contact with the partition.

[0018] Furthermore, the left side wall of the mounting bracket is provided with a terminal plate, and the partition plate has wire-passing holes located in the clearance interval.

[0019] Furthermore, it also includes locking screws. The rear end face of the cabinet and the rear end face of the mounting bracket are respectively provided with threaded holes. When the mounting bracket is located in the electrical compartment, the locking screws are threaded into the threaded holes from back to front, fixing the mounting bracket and the cabinet together.

[0020] The beneficial effects of the above technical solution are:

[0021] This invention utilizes a dedicated mounting rack within the cabinet for power modules, allowing for centralized installation and partitioned arrangement of power modules with other electrical components. This avoids issues such as compact distribution, cross-wiring, and interference during disassembly and assembly, thus enhancing the convenience of modular management and independent maintenance. Furthermore, a rotating mechanism between the cabinet and the mounting rack allows the rack to rotate outwards around its rear left rotation point. With the front compartment open, the right end of the mounting rack can unscrew the electrical compartment, exposing the power modules to the outside of the cabinet. This effectively solves the problem of inconvenient maintenance of power modules in existing charging piles, facilitating maintenance by operators and significantly improving the efficiency of power module maintenance.

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0030] This embodiment aims to provide a charging pile power module installation structure that facilitates maintenance, addressing the problem that the power modules in existing charging piles are inconvenient to maintain.

[0031] A charging pile power module installation structure that facilitates maintenance, such as... Figure 1The system includes a cabinet 1, a mounting bracket 2, and a rotating mechanism 3. The cabinet 1 contains an electrical compartment 101 for installing power modules, controllers, cooling devices, and other power distribution equipment (specific equipment is not shown in the diagram). A front wall covering the electrical compartment 101 is detachably connected to the cabinet 1; the front wall can be removed to open the cabinet 1 from the front, facilitating the installation and maintenance of the power distribution equipment.

[0032] Mounting bracket 2 is a cuboid structure, and its interior is used to install power modules. Mounting bracket 2 has two mounting cavities, upper and lower, which can accommodate two sets of power modules 7.

[0033] A rotating mechanism 3 is installed between the rear end of the left side wall of the cabinet 1 and the mounting bracket 2. The mounting bracket 2 is rotated and set in the electrical compartment 101 through the rotating mechanism 3. There are two sets of rotating mechanisms 3 arranged at the top and bottom.

[0034] The rotating mechanism 3 includes a rotating shaft 301, a bushing 302, and a rotating plate 303. The rotating shaft 301 is fixed to the frame in the vertical direction. Specifically, the rotating shaft 301 is a bent L-shaped structure, including a vertical section extending in the vertical direction and a horizontal section fixedly connected to the vertical section. One end of the rotating shaft 301 is fixedly connected to the top or bottom of the electrical compartment 101, and the other end is bent and fixedly connected to the inner wall of the electrical compartment 101. That is, one end of the vertical section is connected to the top or bottom of the cabinet, and the other end is connected to the horizontal section. The other end of the horizontal section is fixedly connected to the cabinet.

[0035] The bushing 302 is rotatably mounted on the rotating shaft 301. Specifically, the bushing 302 is rotatably adapted to the vertical section. The rotating plate 303 is fixed on the mounting bracket 2, and the bushing 302 is fixedly connected to the rotating plate 303, so that the bushing 302 is indirectly connected to the mounting bracket 2. Each set of rotating shafts 301 is fitted with two sets of bushings 302 at intervals, and both sets of bushings 302 are fixedly connected to the rotating plate 303.

[0036] like Figures 3-6 When the mounting bracket 2 is located inside the electrical compartment 101, the left side wall of the mounting bracket 2 is spaced apart from the left inner wall of the cabinet 1 to provide clearance for the right end of the mounting bracket 2 to rotate out of the electrical compartment 101, allowing the right end of the mounting bracket 2 to rotate out of the electrical compartment 101 smoothly. The clearance space can reserve enough space for installing a heat dissipation device to cool the power module 7.

[0037] like Figure 1 The electrical compartment 101 is horizontally fixed with a partition 4, which divides the electrical compartment 101 into two compartments. The mounting bracket 2 is located in the upper compartment, and the lower compartment is mainly used to install power distribution equipment such as controllers, making the layout more organized and preventing the power module from being covered and surrounded by other electronic components.

[0038] like Figure 2Multiple sets of ball bearing mechanisms 5 are spaced apart on the left and right sides of the bottom of the mounting frame 2. The bottom of the mounting frame 2 is connected to the upper surface of the partition 4 through the ball bearing mechanisms 5. The ball bearing mechanism 5 includes a ball bearing seat 501 and a ball bearing 502; the lower surface of the ball bearing seat 501 is provided with a rolling ball bearing 502, which makes rolling contact with the partition 4. This allows the partition 4 to provide an additional support base for the mounting frame 2, reducing the dependence of the mounting frame 2 on the fixed support provided by the rotating mechanism 3, and improving the stability of the mounting frame 2 when it is located in the electrical compartment 101. The ball bearing mechanisms 5 reduce the friction between the mounting frame 2 and the partition 4 through rolling friction, so that the mounting frame 2 can rotate smoothly.

[0039] The left side wall of the mounting bracket 2 is provided with a terminal plate 201 for wiring the power module. That is, the wiring ports of the power module are concentrated on its left end face, and the terminal plate 201 provides a clearance for its wiring ports.

[0040] The partition 4 has a wire hole 401, which is located in the clearance interval to allow the cable connecting the power module and the controller to pass through. The cable has a certain degree of slack to accommodate the position change of the wiring port when the mounting bracket 2 rotates.

[0041] The rear end face of the cabinet 1 and the rear end face of the mounting bracket 2 are respectively provided with threaded holes. When the mounting bracket 2 is located inside the electrical compartment 101, the locking screw 6 is threaded from back to front into the threaded hole, fixing the mounting bracket 2 and the cabinet 1 in place, so that the mounting bracket 2 can be stably fixed inside the electrical compartment 101 when not under maintenance. When maintenance of the power module is required, the locking screw 6 is removed from the rear end face of the cabinet 1, allowing the mounting bracket 2 to be unlocked and rotated out of the cabinet 1.
