Description

Technical Field

[0001] This utility model belongs to the field of charging pile technology, and specifically relates to the installation structure of the main control board of a charging pile with an insulating isolation bracket. Background Technology

[0002] In the field of new energy charging facilities, charging piles, as the core terminal for power transmission and control, have an internal main control board that undertakes key functions such as charging parameter regulation, safety protection signal processing, and data interaction. The installation stability, electrical safety, and heat dissipation reliability of the main control board directly determine the operating efficiency and service life of the charging pile. Currently, the industry generally adopts the traditional method of "sequential bolt fastening" for installing the main control board of charging piles. Although this method can achieve a fixed connection between the main control board and the cabinet, it has exposed many technical pain points in practical applications and can no longer meet the needs of efficient assembly, safe operation and maintenance, and long-term stable operation of charging piles.

[0003] From the perspective of ease of installation and maintenance, the bolt-type sequential tightening installation method is cumbersome: during installation, the main control board must first be precisely aligned with the pre-set bolt holes in the cabinet, and then the bolts must be inserted and tightened one by one. Due to the limited internal space and dense layout of components in the charging pile cabinet, problems such as tool obstruction and bolt hole misalignment are likely to occur during bolt disassembly and assembly. The installation of a single main control board often requires the cooperation of multiple operators, which is time-consuming. In the later maintenance or troubleshooting, the main power supply of the charging pile must be disconnected first, and then the bolts must be loosened one by one to remove the main control board. If the bolts rust or strip after long-term use, additional rust removal tools or replacement of the cabinet threaded holes are required, further extending the maintenance time, seriously affecting the operation and maintenance efficiency of the charging pile and increasing operating costs.

[0004] More importantly, the main control board is often in direct contact with the metal inner wall of the charging pile cabinet. The charging pile cabinet is mostly made of cold-rolled steel plate, which has high structural strength, but the conductivity of the metal material can easily lead to electrical risks: if the insulation layer of the circuit is damaged or the solder joints fall off during the operation of the main control board, the onboard current may be conducted to the outside through the cabinet. This will not only interfere with the stability of the circuit signal of the main control board itself, causing abnormal charging parameters and failure of safety protection functions, but may also cause the cabinet to become electrified, posing a risk of electric shock to people near the charging pile. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a charging pile main control board mounting structure with an insulated isolation bracket.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a charging pile main control board mounting structure with an insulating isolation bracket, comprising a main control board body, a bracket member provided on one side of the main control board body, a stepped surface formed on the side of the bracket member close to the main control board body that contacts the main control board body, an mounting member embedded in the inner side of the stepped surface, and a movable member extending through to the outer side of the mounting member provided on the inner side of the mounting member; The movable part is fitted with a connector at one end inside the mounting part. The surface of the connector is fitted with an inner ring, and the inner ring is fitted with the mounting part.

[0007] Preferably, the outer surface of the connector is symmetrically fitted with snap-fit ​​components, and the inner side of the inner ring has four snap-fit ​​grooves distributed circumferentially, which are used in conjunction with the snap-fit ​​components.

[0008] Preferably, an elastic element is snapped onto the end of the connector away from the moving element, and a rotating element is snapped onto the end of the elastic element away from the connector.

[0009] Preferably, the outer side of the rotating component is integrally formed with a convex ring, and the inner side of the mounting component is provided with a receiving cavity that fits with the convex ring.

[0010] Preferably, the movable part has a groove at one end located on the outside of the mounting part, and the groove is used to pinch the movable part.

[0011] Preferably, a horizontal plate is snapped onto the outer surface of the movable component, and the horizontal plate is located on the side of the main control board body away from the support component.

[0012] Preferably, one end of the horizontal plate is fitted with a plug rod, and the plug rod penetrates through the main control board body to the inner side of the stepped surface.

[0013] Preferably, the main control board body and the inner side of the stepped surface are provided with insertion holes, which are used in conjunction with the insertion rod, and the inner side of the insertion hole is fixedly bonded with a rubber ring sleeved on the surface of the insertion rod.

[0014] In summary, this utility model has the following beneficial effects: 1. When assembling and installing the main control board of the charging pile with the bracket, the operator pulls the moving part. To ensure that the main control board can be smoothly placed and installed on the surface of the bracket, the operator can rotate the moving part while holding it. After the moving part rotates 90 degrees, the operator can release the force. Under the rebound action, the elastic part will drive the snap-fit ​​part and the snap-fit ​​groove to re-form a snap-fit ​​engagement. This will provide space for the main control board to operate on the surface of the bracket. In this case, the snap-fit ​​groove and snap-fit ​​part ensure that the moving part, which makes way for the main control board, still has a stable limit state after adjustment. At the same time, the mounting part rotates synchronously with the elastic part and the connecting part through the precise fit between the convex ring and the receiving cavity, effectively preventing the elastic part from twisting while undergoing longitudinal deformation, thereby preventing a reduction in its service life. 2. During the installation of the main control board, first place it stably on the stepped surface, then adjust the posture of the main control board body to achieve coaxial alignment between the main control board body and the insertion hole on the stepped surface. Next, operate the moving component to reset the insertion rod to the coaxial position corresponding to the insertion hole. Under the rebound reset action of the elastic component, the insertion rod will gradually penetrate through the insertion hole between the main control board body and the stepped surface, ultimately achieving stable assembly and fixation of the main control board body and the bracket. This structural design combines installation stability and ease of operation. Compared with the existing bolt-type installation method, which has problems such as cumbersome operation and low efficiency, it can significantly reduce the time cost in the installation and disassembly process of the main control board body and improve work efficiency. 3. In the stepped design of the support components, the stepped surfaces form a channel for efficient heat dissipation and ventilation on one side of the main control board. This channel promotes air circulation inside the charging pile, allowing airflow to fully contact both sides of the main control board, effectively reducing the operating temperature of the main control board during operation and ensuring that the main control board is always in a stable and reliable operating state.

[0017] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0018] The specific embodiments of this utility model are described below with reference to the accompanying drawings: Example: refer to Figures 1-6 The charging pile main control board mounting structure with insulating isolation bracket includes a main control board body 100. A bracket 200 is provided on one side of the main control board body 100. A stepped surface 201 is formed on the side of the bracket 200 near the main control board body 100, which contacts the main control board body 100. An installation component 300 is embedded in the inner side of the stepped surface 201, and a movable component 400 is provided on the inner side of the installation component 300, which extends to the outer side of the installation component 300. The movable part 400 is snapped onto one end of the mounting part 300 with a connector 500. The surface of the connector 500 is fitted with an inner ring 600, and the inner ring 600 is snapped onto the mounting part 300.

[0019] Specifically, during the installation of the main control board, it is first placed stably on the stepped surface 201. Then, the posture of the main control board body 100 is adjusted so that it is coaxially aligned with the insertion hole 902 on the stepped surface 201. Next, the moving part 400 is operated to reset the insertion rod 901 to the coaxial position corresponding to the insertion hole 902. Under the rebound reset action of the elastic part 700, the insertion rod 901 will gradually penetrate through the insertion hole 902 on the stepped surface 201, ultimately achieving stable assembly and fixation of the main control board body 100 and the bracket 200. This structural design combines installation stability and ease of operation. Compared with the existing bolt-type installation method, which suffers from cumbersome operation and low efficiency, it can significantly reduce the time cost during the installation and disassembly of the main control board body 100 and improve work efficiency.

[0020] The outer surface of the connector 500 is symmetrically fitted with a snap-fit ​​component 501, and the inner side of the inner ring 600 has four snap-fit ​​grooves 601 distributed in a circular pattern. The snap-fit ​​grooves 601 are used in a snap-fit ​​engagement with the snap-fit ​​component 501. The end of the connector 500 away from the moving component 400 is fitted with an elastic component 700, and the end of the elastic component 700 away from the connector 500 is fitted with a rotating component 800. The outer side of the rotating component 800 is integrally formed with a protruding ring 801, and the inner side of the mounting component 300 is provided with a receiving cavity 802 that fits with the protruding ring 801.

[0021] Specifically, when the movable component 400 moves, it will cause the connecting component 500 to move longitudinally. The connecting component 500 slides and is guided within the locking groove 601 by the locking component 501. While moving the movable component 400 by holding it, the movable component 400 is rotated, causing the locking component 501 to disengage from the locking groove 601. At this time, the elastic component 700 undergoes elastic deformation and extends. The mounting component 300, through the precise engagement of the convex ring 801 and the receiving cavity 802, rotates synchronously with the elastic component 700 and the connecting component 500, effectively preventing the elastic component 700 from twisting while undergoing longitudinal deformation, thereby preventing a reduction in its service life. When the movable component 400 rotates 90 degrees, the operator can release the applied force. Under the rebound action, the elastic component 700 will cause the locking component 501 to re-engage with the locking groove 601, thereby achieving angular limitation of the movable component 400.

[0022] The movable part 400 has a groove 401 at one end located outside the mounting part 300. The groove 401 is used to pinch the movable part 400.

[0023] Specifically, the operator can easily pinch and pull the movable part 400 through the recessed design of the groove 401.

[0024] A horizontal plate 900 is snapped onto the outer surface of the movable part 400, and the horizontal plate 900 is located on the side of the main control board body 100 away from the bracket 200. A plug rod 901 is snapped onto one end of the horizontal plate 900, and the plug rod 901 penetrates the main control board body 100 to the inner side of the stepped surface 201.

[0025] Specifically, when the moving part 400 moves, it will synchronously drive the horizontal plate 900 to generate displacement. When the moving part 400 moves longitudinally, the horizontal plate 900 will drive the insertion rod 901 to achieve the insertion and engagement or separation action with the stepped surface 201 and the main control board body 100. When the moving part 400 rotates for adjustment, the horizontal plate 900 will synchronously link the insertion rod 901, so that the insertion rod 901 and the main control board body 100 and the stepped surface 201 form a state in which they do not overlap or affect each other in the longitudinal direction.

[0026] Both the main control board body 100 and the inner side of the stepped surface 201 are provided with insertion holes 902. The insertion holes 902 are used in conjunction with the insertion rods 901, and the inner side of the insertion holes 902 is fixedly bonded with rubber rings 903 that are sleeved on the surface of the insertion rods 901.

[0027] Specifically, the socket 902 and the plug rod 901 form a plug-in mating structure. The rubber ring 903 installed inside the socket 902 can effectively reduce the mating gap between the two, thereby preventing the main control board body 100 from shaking on the bracket 200 due to the existence of gap, and ensuring the structural stability after assembly.

[0028] The working principle of this utility model is as follows: When assembling and installing the main control board body 100 of the charging pile and the bracket 200, the operator first uses the groove 401 of the movable part 400 to pinch and pull it. When the movable part 400 moves, it will drive the connecting part 500 to move longitudinally. The connecting part 500 is guided to slide within the locking groove 601 by the snap-fit ​​part 501. To ensure that the main control board body 100 can be smoothly placed and installed on the surface of the bracket 200, the operator can rotate the movable part 400 while holding it and moving it, so that the snap-fit ​​part 501 is released from the constraint of the locking groove 601. At this time, the elastic part 700 undergoes elastic deformation and extends. The mounting component 300 is precisely engaged with the receiving cavity 802 via the convex ring 801, and rotates synchronously with the elastic component 700 and the connecting component 500. When the moving component 400 rotates ninety degrees, the operator can release the force, and the elastic component 700 will cause the snap-fit ​​component 501 to re-form a snap-fit ​​engagement with the snap-fit ​​groove 601 under the rebound action, thereby realizing the angular limit of the moving component 400. At this time, it will provide space for the operation of the main control board body 100 on the surface of the bracket component 200.

[0029] After placing the main control board body 100 on the stepped surface 201, and simultaneously aligning the stepped surface 201 with the socket 902 of the main control board body 100, the above operation on the moving part 400 is repeated, and the insertion rod 901 is adjusted back to the alignment with the socket 902. Then, during the springback recovery of the elastic element 700, the insertion rod 901 gradually penetrates the main control board body 100 and the stepped surface 201, thus achieving a stable installation for the assembly of the main control board body 100 and the support part 200. In this embodiment, the elastic element 700 is a spring, but is not limited to shape memory alloys, torsion springs, disc springs, etc.

[0030] The stepped surface 201 design of the bracket 200 creates an efficient heat dissipation and ventilation channel on one side of the main control board body 100. This channel promotes air circulation inside the charging pile.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
