Description

Technical Field

[0001] This utility model belongs to the field of charging gun technology, specifically relating to a new energy vehicle charging structure with good sealing performance. Background Technology

[0002] A charging gun is a charging device that connects a charging station to an electric vehicle. It is a tool that transfers electricity from the power source to the car battery. It is generally called a charging gun or charging plug, and mainly includes DC charging guns and AC charging guns.

[0003] The charging gun contains many electrical components, such as wires, plugs, and control chips. Water is a good conductor of electricity. When rainwater enters the charging gun, it may cause an electrical short circuit. A short circuit can cause circuit failure, generate electric sparks, and potentially cause a fire, posing a serious threat to the surrounding environment and personnel safety. Therefore, it is essential to protect the charging gun from rain.

[0004] Currently, there are many different rainproof measures for charging guns.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-4The present invention provides the following technical solution: a new energy vehicle charging structure with good sealing performance, including a gun body 1, a connector 11 fixed to the head end of the gun body 1, a charging terminal 12 embedded and fixed in the connector 11, and a cable 13 connected to the gun body 1 from the tail end. A buckle 14 is also fixed at the head end of the gun body 1. The device also includes a rubber rain cover 2, a front protective cover 3, and a first rubber sealing ring 5.

[0035] Furthermore, by Figure 1 and Figure 2 As shown, in this embodiment, the rubber rain cover 2 has a horn-shaped structure and is fixed to the head end of the gun body 1. A water-permeable hole 21 is provided on the bottom side of the rubber rain cover 2. The front protective cover 3 is placed on the connector 11, and the first rubber sealing ring 5 is fixed on the connector 11. With the above solution, when charging a new energy vehicle, first remove the front protective cover 3, then insert the connector 11 into the charging socket of the new energy vehicle. The charging terminal 12 is electrically connected to the charging socket of the vehicle to charge the new energy vehicle. At this time, the rubber rain cover 2 undergoes elastic deformation. It closely adheres to new energy vehicles, achieving a superior sealing effect, protecting the charging terminal 12 from rain and dust, and preventing electrical short circuits. In addition, the design of the water-permeable hole 21 not only allows rainwater that accidentally enters the rubber rain cover 2 to drain in time, but also provides ventilation and heat dissipation. When not in use, the front protective cover 3 is placed on the connector 11. At this time, the front protective cover 3 compresses the first rubber sealing ring 5, achieving a superior sealing effect, protecting the charging terminal 12 from rain and dust. It provides excellent protection, especially for small home charging piles that lack a gun head storage device.

[0036] Preferably, by Figure 1 and Figure 2 As shown, this embodiment also includes a connecting rope 4, one end of which is fixedly connected to the gun body 1 and the other end is fixedly connected to the front protective cover 3. With the above solution, when in use, one end of the connecting rope 4 is fixedly connected to the gun body 1 with a rivet and the other end is fixedly connected to the front protective cover 3 with a rivet, ensuring that the front protective cover 3 is always connected to the gun body 1 and preventing the front protective cover 3 from being lost.

[0037] Preferably, by Figure 1 and Figure 2 As shown, this embodiment also includes a protective sleeve 31, which is fixed inside the front protective cover 3. When the front protective cover 3 is placed on the connector 11, the protective sleeve 31 is placed on the charging terminal 12. With the above solution, the protective sleeve 31 can further protect the charging terminal 12 during use, preventing rain or dust from causing unnecessary damage to the charging terminal 12, and greatly improving the safety of the charging gun.

[0038] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, anti-slip textures 32 are evenly distributed on the outer wall of the front protective cover 3. With the above solution, the anti-slip textures 32 make it easier to install and remove the front protective cover 3 during use, increasing the friction between the fingers and the front protective cover 3 and preventing slippage.

[0039] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, a guide slope 51 is provided at the end of the first rubber sealing ring 5. With the above scheme, the design of the guide slope 51 has a better guiding function when in use. When installing the front protective cover 3, it is more conducive to the front protective cover 3 passing over the first rubber sealing ring 5 and squeezing the first rubber sealing ring 5, ensuring a better sealing effect and protective function. At the same time, it is also conducive to further improving the stability of the installation of the front protective cover 3.

[0040] Preferably, by Figure 1 and Figure 4 As shown, this embodiment also includes a rear protective cover 6, which is installed at the tail end of the gun body 1 by a threaded engagement. A guide hole 61 for the cable 13 to pass through is machined on the rear protective cover 6. With the above solution, the cable 13 is guided by the rear protective cover 6 during use, and the interface between the cable 13 and the gun body 1 is protected to prevent rainwater and dust from entering the gun body 1 from the interface between the cable 13 and the gun body 1, thereby further improving the safety of the charging gun.

[0041] Preferably, by Figure 1 and Figure 4 As shown, this embodiment also includes a second rubber sealing ring 7, which is bonded and fixed inside the rear protective cover 6. When the rear protective cover 6 is tightened, the rear protective cover 6 and the gun body 1 press against the second rubber sealing ring 7. With the above solution, the second rubber sealing ring 7 further improves the sealing performance of the rear protective cover 6 during use, and improves the protective effect of the rear protective cover 6, preventing rainwater and dust from entering the gun body 1 from the interface between the cable 13 and the gun body 1.

[0042] Preferably, by Figure 1 and Figure 4As shown, this embodiment also includes a rubber disc 8, which is fixed inside the guide hole 61. The rubber disc 8 has a frustum-shaped hole 81 through which the cable 13 passes. The inner diameter of the smaller end of the frustum-shaped hole 81 is smaller than the diameter of the cable 13. With the above solution, the design of the frustum-shaped hole 81 makes it easy for the cable 13 to pass through the frustum-shaped hole 81 during use. After the cable 13 passes through the frustum-shaped hole 81, the frustum-shaped hole 81 will expand by a certain distance. At the same time, the rubber disc 8 fits tightly against the outer wall of the cable 13, which further improves the sealing effect and protection performance, and prevents rainwater and dust from entering the gun body 1 from the gap between the cable 13 and the guide hole 61, thereby further improving the safety of the charging gun.

[0043] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0044] Components not described in detail in this article are existing technologies.

[0045] The working principle and usage process of this utility model: When using the new energy vehicle charging structure of this utility model, first remove the front protective cover 3, then insert the connector 11 into the charging socket of the new energy vehicle, and the charging terminal 12 is electrically connected to the charging socket of the vehicle to charge the new energy vehicle.

[0046] At this time, the rubber rain cover 2 undergoes elastic deformation and fits tightly against the new energy vehicle, achieving a better sealing effect, protecting the charging terminal 12 from rain and dust, and preventing electrical short circuits.

[0047] In addition, the design of the water-permeable holes 21 can not only drain rainwater that accidentally enters the rubber rain cover 2 in time, but also play a role in ventilation and heat dissipation.

[0048] When not in use, the front protective cover 3 is placed on the connector 11. At this time, the front protective cover 3 presses the first rubber sealing ring 5, achieving a better sealing effect and protecting the charging terminal 12 from rain and dust. This is especially effective for small home charging piles that lack a gun head storage device.

[0049] In another aspect of this utility model, the cable 13 is guided by the rear protective cover 6, and the sealing effect and protection performance are further improved by the second rubber sealing ring 7 and the rubber disc 8. At the same time, the interface between the cable 13 and the gun body 1 is protected to prevent rainwater and dust from entering the gun body 1 from the interface between the cable 13 and the gun body 1.
