Description

Technical Field

[0001] This utility model relates to the field of electric vehicle charging port technology, specifically a waterproof and sealed structure for an electric vehicle charging interface. Background Technology

[0002] Electric vehicle charging interfaces are primarily used for charging and also have the potential to output electrical energy, but their use must be strictly limited. Current technology typically uses a single flip cover to protect the charging port, but this cover only provides waterproofing when the charging interface is not charging. Once the charging connector is connected, the cover only waterproofs the area above the connection, leaving the sides vulnerable to water ingress, resulting in poor protection. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a waterproof sealing structure for electric vehicle charging interfaces, which has the advantage of effectively waterproofing the charging port. It solves the problem that existing technologies typically use a single flip cover to protect the charging interface, but the flip cover can only waterproof the charging interface when it is not charging.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A waterproof sealing structure for an electric vehicle charging interface includes a vehicle body as the main structural component. The vehicle body has a charging port, and a charging head for charging the vehicle body can be installed at the charging port. A waterproof protective shell is installed at the charging port. Multiple ventilation holes for heat dissipation are provided at the bottom of the protective shell. A connecting wire is fixedly connected to the bottom of the protective shell, and a sealing plate is fixedly connected to the connecting wire. Two locking blocks are fixedly connected to one side of the sealing plate. Two locking slots are provided on the protective shell for engaging with the locking blocks. A connecting plate is fixedly connected to the charging head. When the charging head and charging port are installed, a sealing strip installed on one side of the connecting plate fits into the side wall of the protective shell.

[0005] Preferably, the top and bottom of the protective shell are both sloped, and the top is provided with multiple drainage channels.

[0006] Preferably, both the sealing plate and the connecting plate have multiple vertical grooves on one side. After the sealing plate and the connecting plate are installed with the protective shell, the vertical grooves are connected to the drainage channel.

[0007] Preferably, a mounting groove is provided on one side of the vehicle body, and a mounting bracket can be installed in the mounting groove.

[0008] Preferably, one side of the mounting bracket is fixedly connected to one side of the protective shell, and both sides of the sealing plate are fixedly connected with circular plates that are easy to disassemble and assemble.

[0009] Preferably, a wire is installed on one side of the charging head, a rubber sleeve is installed at the end of the wire near the charging head, and a protective tube is installed on the outside of the rubber sleeve.

[0010] By employing the above technical solution, this utility model provides a waterproof sealing structure for an electric vehicle charging interface, which has at least the following beneficial effects: 1. This utility model effectively protects the charging port of an electric vehicle when it is not charging by setting a protective shell and a sealing plate. When the vehicle needs to be charged, the sealing plate is pulled apart from the protective shell by the round plate. At this time, the charging head is connected to the charging port, so that the sealing strip fits into the inner wall of the protective shell and the connecting plate is attached to the protective shell, thereby completing the waterproof protection of the charging head and charging port and ensuring the waterproof effect of the charging interface.

[0011] 2. This utility model enables the sealing plate or connecting plate to effectively guide external water after being connected to the protective shell by setting drainage channels and vertical channels. The inclined surface of the protective shell further prevents rainwater from accumulating at the charging port. The ventilation openings enable the vehicle body to effectively dissipate heat during charging and prevent water from entering, thus ensuring the safety of the mechanism. Attached Figure Description

[0014] 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.

[0015] In the prior art, in order to effectively protect the charging interface of electric vehicles, a single flip cover is usually set to protect the charging port. However, the flip cover can only waterproof the charging port when it is not charging. After the charging cable is connected to the charging port, the flip cover can only waterproof the top of the connection port, and water can still enter the sides, resulting in poor protection. The following describes a waterproof sealing structure for the charging interface of an electric vehicle provided by some embodiments of this utility model with reference to the accompanying drawings.

[0016] Example 1: Combination Figures 1-4 As shown, a waterproof and sealed structure for an electric vehicle charging interface is proposed. The structure consists of a vehicle body 1 as the main body, a charging port 3 on the vehicle body 1, and a charging head 2 for charging the vehicle body 1 can be installed at the charging port 3. The vehicle body 1 is charged by connecting the charging head 2 and the charging port 3.

[0017] To effectively waterproof the charging port 3, a waterproof protective shell 4 is installed at the charging port 3. The bottom of the protective shell 4 has multiple ventilation holes 5 for heat dissipation. A connecting line 6 is fixedly connected to the bottom of the protective shell 4, and a sealing plate 7 is fixedly connected to the connecting line 6. Two locking blocks 8 are fixedly connected to one side of the sealing plate 7. The protective shell 4 has two slots 9 for engaging with the locking blocks 8. The engagement of the locking blocks 8 and the slots 9 allows the vehicle body 1 to waterproof and seal the charging port 3 when not charging by installing and connecting the protective shell 4 and the sealing plate 7, thus effectively protecting the charging port 3 when the vehicle body 1 is not charging.

[0018] In order to effectively protect the vehicle body 1 during charging, a connecting plate 11 is fixedly connected to the charging head 2. After the charging head 2 and the charging port 3 are installed, the sealing strip 13 installed on one side of the connecting plate 11 fits into the side wall of the protective shell 4. The sealing strip 13 fits into the side wall of the protective shell 4, so that the connecting plate 11 can be tightly connected to the protective shell 4 after the charging head 2 and the charging port 3 are installed, thereby effectively protecting the charging head 2 and the charging port 3.

[0019] Example 2: Based on Embodiment 1, the technical solution proposed in Embodiment 1 is used to solve the problem that in the prior art, a single flip cover is usually set to protect the charging interface. However, the flip cover can only waterproof the charging interface when it is not charging. After the charging connector is connected to the charging interface, the flip cover can only waterproof the top of the connection port, and water can still enter the side. However, when the vehicle body encounters rain during charging in the outside environment, some rainwater will remain near the protective shell 4, which reduces the safety of the vehicle body 1.

[0020] To prevent rainwater from remaining at charging head 2 and charging port 3, combined with Figure 1 and Figure 3 as well as Figure 4As shown, by making the top and bottom of the protective shell 4 sloped, rainwater can slide freely from the top of the protective shell 4. The top is provided with multiple drainage channels 10, and the sealing plate 7 and the connecting plate 11 are provided with multiple vertical grooves 12 on one side. When the sealing plate 7 and the connecting plate 11 are installed with the protective shell 4, the vertical grooves 12 are connected to the drainage channels 10, so that the rainwater can be effectively guided during the sliding process and is not easy to remain near the protective shell 4, which further improves the protective effect of the structure.

[0021] A mounting slot 14 is provided on one side of the vehicle body 1. A mounting bracket 15 can be installed in the mounting slot 14. One side of the mounting bracket 15 is fixedly connected to one side of the protective shell 4. Both sides of the sealing plate 7 are fixedly connected with round plates that are easy to disassemble and assemble. A wire is installed on one side of the charging head 2. A rubber sleeve 17 is installed on the end of the wire near the charging head 2. A protective tube 16 is installed on the outside of the rubber sleeve 17. The rubber sleeve 17 effectively protects the connection end between the wire and the charging head 2. The protective tube 16 prevents the connection end from bending excessively, thereby improving the service life of the charging head 2.

[0022] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
