Description

Technical Field

[0001] The utility model relates to the technical field of protection of charging pile charging modules, in particular to an anti-impact protection structure for charging pile charging modules. Background Art

[0002] The charging module of the charging pile, also known as the power module, is the core component of the charging pile. Its main function is to convert AC power into DC power, thereby providing a stable charging power supply for electric vehicles. The performance of the charging module directly affects the charging efficiency, stability and safety of the charging pile. Therefore, when designing and manufacturing charging piles, the selection and configuration of the charging module are extremely important. Specifically, the working principle of the charging module includes key steps such as input filtering, rectification, voltage transformation, control and output filtering. First, the AC power is filtered through the input filter circuit to prevent problems such as interference signals and power supply fluctuations, and to ensure the stability and reliability of the power supply. Then, the AC power is converted into DC power through the rectifier circuit. Next, the DC power is adjusted by the transformer circuit to adapt to the voltage required by the electric vehicle. Finally, the precise control of the charging process is achieved through the control module.

[0003] For example, the Chinese authorized patent "A Shell and Charging Module" with announcement number CN217427729U, the shell includes an upper shell and a lower shell, the upper shell and the lower shell are buckled to form a cylindrical structure with two ends open, the upper shell and the lower shell are connected by snap-fit, and the shell also includes a first baffle and a second baffle, the first baffle and the second baffle are respectively fixed at the two ends of the cylindrical structure to fasten the upper shell and the lower shell. The first baffle and the second baffle play a role in fixing and connecting the upper shell and the lower shell, and there is no need to set up additional connectors at the buckling point of the upper shell and the lower shell for connection, which improves the convenience of assembling and disassembling the shell, and greatly improves the efficiency of disassembling the shell; and the upper shell and the lower shell are connected by snap-fit, which is conducive to preventing gaps from appearing at the connection, thereby improving the EMC efficiency of the charging module.

[0004] The above-mentioned prior art will inevitably encounter collisions with various objects or tools during the movement, installation or use of the charging pile. Since there is no protective mechanism, the charging module may be damaged, thereby affecting its normal operation. Therefore, it does not meet the existing needs. In this regard, we propose an impact-resistant protection structure for the charging module of the charging pile. Utility Model Content

[0005] The purpose of the utility model is to provide an impact-resistant protection structure for a charging pile charging module, so as to solve the problem that the charging pile proposed in the above background technology is prone to collision with various objects or tools during movement, installation or use, thereby affecting its normal operation.

[0006] To achieve the above object, the utility model provides the following technical solution: an impact-resistant protective structure for a charging module of a charging pile, comprising a charging module housing, wherein a protective housing is arranged outside the charging module housing; and further comprising:

[0007] A buffer mechanism is arranged between the protective shell and the charging module shell, the buffer mechanism includes a damping buffer, and the fixed end of the damping buffer is fixed to the protective shell by a thread, the movable end of the damping buffer is installed with a limit slide bar, and the limit slide bar is connected to the movable end of the damping buffer by a bearing, and a first buffer spring is installed between the movable end and the fixed end of the damping buffer;

[0008] A limiting slide groove is arranged on both sides of the upper end surface and the lower end surface of the charging module shell, and the limiting slide groove is slidably connected to the limiting slide bar. The upper and lower ends of both sides of the charging module shell are provided with mounting holes, and locking bolts are installed inside the mounting holes, and the locking bolts are adapted to the inner screw holes of the limiting slide bar.

[0009] Preferably, a grounding protective plate is provided at the rear end of the protective shell, the front end of the grounding protective plate extends to the interior of the protective shell, and the grounding protective plate is slidably connected to the protective shell, the interior of the front end of the grounding protective plate is provided with annularly distributed concave holes, the interior of the concave holes is provided with a second buffer spring, and the two ends of the second buffer spring are respectively fixed to the grounding protective plate and the protective shell.

[0010] Preferably, a base is provided at the rear end of the grounding protection plate, and the base and the grounding protection plate are integrally cast, and the base is flush with the protective shell.

[0011] Preferably, through holes are provided on the upper and lower sides of both sides of the protective shell, and the positions of the through holes correspond to the mounting holes.

[0012] Preferably, a silicone pad is provided in the interlayer of the inner wall of the charging module housing.

[0013] Preferably, a front fixing plate is provided at the front end of the protective shell, and the front fixing plate is fixed to the protective shell by welding.

[0014] Preferably, the upper end surface of the protective shell is provided with equidistantly distributed heat dissipation grilles.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model provides a protective shell on the outside of the charging module shell, and a buffer mechanism composed of a damping buffer and a buffer spring is provided between the charging module shell and the protective shell. When the charging pile is subjected to external impact or vibration, the protective shell first bears these impact forces. The solid structure of the protective shell can effectively disperse and weaken the impact forces to prevent them from directly acting on the charging module shell. Subsequently, these impact forces are transmitted to the buffer mechanism through the protective shell. The damping buffer and buffer spring in the buffer mechanism play a role of further buffering and energy absorption. The damping buffer can absorb and consume part of the impact force and reduce the energy transmitted to the charging module shell. The buffer spring disperses and buffers the remaining impact force through its elastic deformation to minimize the vibration and impact on the charging module shell. The buffer mechanism forms an elastic support structure between the charging module shell and the protective shell. When subjected to impact or vibration, the structure can effectively isolate and absorb the impact force to protect the charging module from damage. It can also reduce the noise and mechanical stress caused by vibration, thereby improving the stability and reliability of the charging pile.

[0017] 2. The utility model can realize flexible disassembly and assembly between the charging module shell and the protective shell. When installing the protective shell, it is only necessary to align the limit slide bar with the limit slide groove on the upper and lower end surfaces of the charging module shell, and push the protective shell to make the limit slide bar extend toward the inside of the limit slide groove until the charging module shell contacts the front fixing plate. At this time, a locking bolt is used to pass through the through hole on the outer wall of the protective shell, and the locking bolt is rotated at the mounting hole position. The inner screw hole of the limit slide bar extends to the inside through thread friction, thereby forming a fixation of the limit slide bar and the charging module shell. The installation structure is convenient and easy to operate, and has high stability, which is convenient for daily disassembly and maintenance.

[0018] 3. The utility model sets a grounding protective plate at the rear end of the protective shell. During maintenance work, after the charging module is pulled out from the charging pile, it is generally placed on the ground in an upright posture. The grounding protective plate can preferentially form contact with the ground and extend toward the inside of the protective shell under pressure, squeezing the second buffer spring, thereby reducing the squeezing of the protective shell by the ground, further avoiding damage to the charging module caused by impact with the ground due to rapid placement, and under the influence of the elastic force of the second buffer spring and the gravity of the charging module, the grounding protective plate will not pop out after shrinking, thereby not causing instability of the charging module.

[0028] When the charging pile is subjected to external impact or vibration, the protective shell 1 first bears these impact forces. The solid structure of the protective shell 1 can effectively disperse and weaken the impact forces to prevent them from directly acting on the charging module shell 8. Subsequently, these impact forces are transmitted to the buffer mechanism through the protective shell 1. The damping buffer 6 and the first buffer spring 9 in the buffer mechanism play a role of further buffering and energy absorption. The damping buffer 6 can absorb and consume part of the impact force and reduce the energy transmitted to the charging module shell 8. The first buffer spring 9 disperses and buffers the remaining impact force through its elastic deformation, thereby minimizing the vibration and impact on the charging module shell 8. The buffer mechanism forms an elastic support structure between the charging module shell 8 and the protective shell 1.
