Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, in particular to a charging pile connection port component with an anti-falling structure. Background Art

[0002] The charging pile connection port assembly refers to the interface component used for charging electric vehicles, also known as a charging plug or charging interface, which is usually composed of a shell, an internal electrical connector and a wiring harness. In the electric vehicle charging system, the charging pile connection port assembly plays an important role. It is a key part for the transmission of electric energy between the electric vehicle and the charging pile. Through the connection port assembly, the electric vehicle can establish an electrical connection with the charging pile to realize the transmission and charging process of electric energy. In the existing literature, there is an explosion-proof plug interface (CN212810694U), which moves the sliding cap on the periphery of the plug interface to cause the sliding groove on the inner side of the sliding cap to slide with the sliding strip on the outer surface of the plug interface, so that one end of the sliding cap is connected to the periphery of the line connector, and cooperates with the rubber ring bonded to the port of the sliding cap to achieve sealing and shielding of the connection between the plug interface and the line connector, avoiding the problem of dust accumulation and foreign matter entering the connection between the plug interface and the line connector, thereby increasing the explosion-proof effect of the plug interface. At least the following defects are exposed during use:

[0003] 1. Due to long-term and frequent plugging and unplugging of the charging cable, the wear of the connection port component shell may cause its fixation to weaken. When the shell becomes loose, the charging cable may shake or become unstable when inserted into the connection port. In severe cases, it may fall off, affecting normal charging.

[0004] 2. Long-term use or high-power fast charging may cause the temperature of the connection port components to rise. If the temperature rises too high, it may affect the normal operation of the connection port components and even damage the internal components. Utility Model Content

[0005] The purpose of the utility model is to provide a charging pile connection port assembly with an anti-falling structure to solve the problems of the existing charging pile connection port assembly during use proposed in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A charging pile connection port assembly with an anti-falling structure comprises a charging pile, a protective shell is arranged on the outer side of the charging pile, the protective shell is composed of a heat dissipation shell and an outer shell, a mounting block is fixedly connected to the outer side of the charging pile; a circular groove is opened at one end of the mounting block; a spring two, one end of which is fixedly connected to the inner side of the mounting block; a handle two, which is fixedly connected to one end of the spring two; a limit block is installed in the middle of one side of the handle two; a limit groove is opened through the outer end of the protective shell; and a heat conductor is arranged between the heat dissipation shell and the outer shell.

[0008] Preferably, one end of the spring is located in a circular groove, a U-shaped body is installed on one side of the mounting block, and the lower end of the handle can slide along the inner side of the U-shaped body.

[0009] Preferably, it is characterized in that the heat conductor is in a truncated cone shape, the end of the heat conductor with a larger area is fixedly connected to the outer side of the shell, and the end of the heat conductor with a smaller area is fixedly connected to the inner side of the heat dissipation shell.

[0010] Preferably, it is characterized in that a connecting block is installed on the outside of the charging pile, through holes are opened on both sides of one end of the connecting block, and a spring is installed on the outside of the charging pile.

[0011] Preferably, it is characterized in that one end of the spring is fixedly connected to a handle one, grooves are provided on both sides of the handle one, a connecting shaft is installed inside the handle one, and a movable cover is installed at a lower end of the handle.

[0012] Preferably, it is characterized in that the connecting shaft is located in the groove of handle 1, and the connecting shaft can pass through the through hole and rotate along it.

[0013] Preferably, it is characterized in that a sealing connecting plate is provided at the connection between the heat dissipation shell and the outer shell, and a sealing ring is provided on the inner side of the outer shell.

[0014] The present invention provides a charging pile connection port assembly with an anti-drop structure, which has the following beneficial effects:

[0015] 1. By setting the mounting block, spring 2, handle 2, limit block and limit groove, the limit block can pass through the limit groove of the protective shell, and by pushing handle 2, the spring 2 is compressed into the limit groove in the mounting block, so that the limit block is moved out of the protective shell, which is convenient for pulling out the plug. When the handle is not pulled, the limit block is located in the limit groove, and the connecting plug is stuck, thereby firmly fixing the connecting plug, reducing the occurrence of shaking or instability, preventing it from falling off, and reducing the impact on normal charging.

[0016] 2. By setting up a heat dissipation shell and a heat conductor, the truncated cone design can improve the heat dissipation effect by increasing the heat dissipation area. The end with a larger area on the heat conductor is connected to the shell, which can better absorb the heat in the connector and exchange heat with the surrounding environment. The heat dissipation shell, as a part of the connection port assembly, can transfer the heat absorbed by the heat conductor to the surrounding environment, thereby improving the overall heat dissipation efficiency and reducing the damage of high temperature to the internal components of the connection port.

[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] Example: Figure 1 Figure 2 As shown, a charging pile connection port assembly with an anti-falling structure includes a connection port protection shell 3 arranged on the outside of the charging pile 1, and an outer movable cover 2 can cover the protection shell 3 and the connection port to prevent the entry of external impurities. A through hole 5 is opened at one end of the outer connection block 4 of the charging pile 1, and a connecting shaft 8 in the middle of a handle 7 at the upper end of the movable cover 2 can pass through the through hole 5. When the handle 7 is pushed, the connecting shaft 8 can rotate in the through hole 5 through a groove 9, thereby driving the lower end movable cover 2 to rotate, and the charging plug can be connected to the connection port of the charging pile 1 for charging by flipping up the movable cover 2.

[0026] like Figure 3 Figure 4As shown, a circular groove 11 is provided at one end of the mounting block 10 outside the charging pile 1, and a spring 2 13 on one side of the handle 2 14 is fixedly connected to the mounting block 10 and is located in the circular groove 11. The lower end of the handle 2 14 can slide in the U-shaped body 12 on one side of the mounting block 10, so that the limit block 15 on the right side of the handle 2 14 is inserted into the limit groove 16 of the protective shell 3. The limit block 15 can clamp the connecting plug, thereby firmly fixing the connecting plug, reducing shaking or instability, preventing it from falling off, and reducing the impact on normal charging. When the handle 2 14 is pushed toward the mounting block 10, the spring 2 13 is compressed and displaced, and the limit block 15 on one side of the handle 2 14 can be separated from the limit groove 16 of the protective shell 3, which is convenient for the connection plug to be taken out. When the U-shaped body 12 is convenient for loosening the handle 2 14, the elastic force of the deformation of the spring 2 13 accurately pushes the limit block 15 into the limit groove 16 through the handle 2 14.

[0027] like Figure 5 As shown, the protective shell 3 composed of the outer shell 302 and the heat dissipation shell 301 dissipates the heat inside the connection port through the heat conductor 17 connected between the outer shell 302 and the outer heat dissipation shell 301. The design of the truncated cone-shaped heat conductor 17 can improve the heat dissipation effect by increasing the heat dissipation area. The end of the heat conductor 17 with a larger area is connected to the outer shell 302, and the end with a smaller area is connected to the heat dissipation shell 301, which can transfer heat from the outer shell 302 to the heat dissipation shell 301. The heat dissipation shell 301, as a part of the connection port, transfers the heat absorbed by the heat conductor 17 to the surrounding environment. The heat conductor 17 is made of copper metal with high heat transfer performance, which improves the overall heat dissipation performance and reduces the impact of the high temperature inside the connection port on the electronic components.

[0028] Working principle: The movable cover 2 can cover the protective shell 3 and the connection port to prevent the entry of foreign matter. When the handle 1 7 is pushed, the connecting shaft 8 can rotate in the through hole 5 through the groove 9, thereby driving the lower end movable cover 2 to rotate. The movable cover 2 can be turned up to connect the charging plug to the connection port of the charging pile 1 for charging. The lower end of the handle 2 14 can slide in the U-shaped body 12 on one side of the mounting block 10, so that the limit block 15 on the right side of the handle 2 14 is inserted into the limit groove 16 of the protective shell 3. The limit block 15 can clamp the connection plug, and the handle 2 1 When the mounting block 10 is pushed in the direction of the mounting block 10, the spring 13 is compressed and displaced, and the limit block 15 on one side of the handle 14 can be separated from the limit groove 16 of the protective shell 3, so that the plug can be connected and removed. When the U-shaped body 12 is easy to release the handle 14, the elastic force of the spring 13 is deformed to accurately push the limit block 15 into the limit groove 16 through the handle 14, and the heat conductor 17 can transfer heat from the shell 302 to the heat dissipation shell 301. The heat dissipation shell 301, as a part of the connection port, transfers the heat absorbed by the heat conductor 17 to the surrounding environment.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
