Description

Technical Field

[0001] This utility model relates to the field of new energy charging equipment technology, specifically a waterproof and sealed rotating protective sleeve for a charging gun head. Background Technology

[0002] Currently, there are two main ways to place the charging guns of new energy charging piles when they are not in use: one is to insert them into the charging gun base that comes with the charging pile, and the other is to hang them directly on the bracket. In the direct hanging method, the charging gun head needs to be sealed separately to prevent water or dust from entering the charging socket and causing short circuits or poor contact at the terminals.

[0003] Currently, the sealing operation of these charging gun heads basically involves using a rotating protective cover (or sleeve) to directly slip onto the charging gun head, utilizing the locking mechanism at the end of the charging gun to prevent it from detaching. However, the design of the current charging gun head protective cover is simple; it is merely a plastic cover that fits the shape of the charging gun head. After the protective cover is slipped onto the charging gun head, there are noticeable gaps on the inside of the cover, resulting in less than ideal waterproofing.

[0004] To address this, we propose a waterproof, sealed, rotating protective sleeve for the charging gun head. Utility Model Content

[0005] The purpose of this invention is to provide a waterproof, sealed, rotating protective sleeve for charging gun heads to solve the aforementioned problems in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a waterproof, sealed, rotating protective sleeve for a charging gun head, including a gun head protective sleeve, a suspension rope, and a hanging ring fixed to the end of the suspension rope for mounting on the charging gun cable. The tail end of the gun head protective sleeve is fastened with a tail end cap, and the middle part of the tail end cap is rotatably connected to the front end of the suspension rope.

[0008] Furthermore, a rubber strip is attached to the inner side of the front opening of the gun head protective sleeve; a positioning plate is also provided on the inner side of the tail end of the gun head protective sleeve, as well as several insertion pins fixed on the positioning plate, and a waterproof rubber ring is fixed on the outer side of each insertion pin.

[0009] Furthermore, the adhesive strip is composed of a flexible rubber strip adhered to the inside of the gun head protective sleeve and a fine velvet spray coating with a thickness of 0.2-0.5 mm laminated on the surface of the flexible rubber strip.

[0010] Furthermore, each of the aforementioned plug pins corresponds to a plug position on the end of a charging gun, and each plug pin is a hollow cylindrical design.

[0011] Furthermore, the tail end of each of the plug pins is recessed inward to form an adapter groove, and a positioning prism is integrally formed in the center of the adapter groove. An installation post is integrally formed at the middle of the tail end of the positioning prism. A ring groove with a T-shaped cross-section is formed around the middle of each plug pin for installing a waterproof rubber ring.

[0012] Furthermore, a rubber pad is provided between the positioning plate and the tail end of the plug pin. The side of the rubber pad that is close to the plug pin is integrally formed with a washer that matches the adapter groove at the tail end of each plug pin. Each washer has an clearance hole at its center that fits on the outside of the positioning prism.

[0013] Furthermore, the positioning plate has a positioning hole that matches the size of the positioning prism at the tail end of each plug pin. The mounting post at the tail end of the plug pin slides through the sealing end of the gun head protective sleeve and is screwed with a mounting cap. The mounting post has a cylindrical design and the inner wall of the hole is threaded. The mounting cap is a quick-release flat cap bolt design.

[0014] Furthermore, the waterproof rubber ring includes a retaining ring that engages with the annular groove. The outer side of the retaining ring is integrally formed with an inner rubber ring and an outer rubber ring. The inner rubber ring is flat against the surface of the insertion pin, while the outer rubber ring and the inner rubber ring are inclined at 30-45 degrees to form a Y-shaped waterproof structure. The opening between the outer rubber ring and the inner rubber ring faces the rubber pad.

[0015] Furthermore, a support ring is integrally formed at the edge of the gun head protective cover, and another anti-detachment ring is integrally formed on the outer side of the gun head protective cover near the tail end. An annular edging is integrally formed on the edge of the tail end cover, and an anti-detachment groove adapted to the anti-detachment ring is integrally formed on the inner side of the edging of the tail end cover. A buckle groove adapted to the locking buckle on the charging gun is also integrally formed on the top of the front end of the gun head protective cover.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the overall structural design of this utility model, by setting an adhesive strip on the inner side of the gun head protective sleeve near the opening, a significant gap can be effectively avoided between the gun head protective sleeve and the outer side of the charging gun front end. Secondly, by setting a cylindrical plug pin inside the gun head protective sleeve and using a Y-shaped waterproof rubber ring on the outer side of the plug pin, the device not only has a waterproof effect far exceeding that of traditional charging gun protective covers, but also, the plug pin, in conjunction with the gun head protective sleeve, can effectively improve the stability of the insertion and engagement between the rotating protective sleeve and the charging gun front end, ensuring that the waterproof effect is not easily interfered with by external forces.

[0027] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0028] Example:

[0029] To address the shortcomings of conventional rotating protective covers for charging gun heads, which have a simple structure and leave noticeable gaps on the inside after being fitted onto the front of the charging gun, resulting in unsatisfactory waterproofing, we propose a waterproof and airtight rotating protective cover for charging gun heads with significantly improved waterproofing. The specific solution is as follows:

[0030] like Figure 1-7 As shown, the present invention provides a waterproof, sealed, rotating protective sleeve for a charging gun head, comprising a gun head protective sleeve 1, a suspension rope 8, and a hanging ring 9 fixed to the end of the suspension rope 8 for mounting on the charging gun cable. The tail end of the gun head protective sleeve 1 is fastened with a tail end cap 2, the middle of which is rotatably connected to the front end of the suspension rope 8. A support ring 101 is integrally formed along the edge of the tail end of the gun head protective sleeve 1, and an anti-detachment ring 102 is integrally formed on the outer side of the gun head protective sleeve 1 near the tail end. An annular edging 201 is integrally formed along the edge of the tail end cap 2, and an anti-detachment groove adapted to the anti-detachment ring 102 is integrally formed on the inner side of the edging 201 of the tail end cap 2. A buckle groove 3 adapted to the buckle on the charging gun is also integrally formed on the top of the front end of the gun head protective sleeve 1.

[0031] To avoid a noticeable gap between the gun head protective sleeve 1 and the charging gun head, a strip of adhesive 7 is attached to the inside of the front opening of the gun head protective sleeve 1. Furthermore, to prevent the adhesive strip 7 from making insertion between the gun head protective sleeve 1 and the charging gun head difficult, the adhesive strip 7 is composed of a flexible rubber strip attached to the inside of the gun head protective sleeve 1 and a fine velvet coating with a thickness of 0.2-0.5 mm applied to the surface of the flexible rubber strip. The elasticity of the flexible rubber strip fills the gap between the gun head protective sleeve 1 and the charging gun head, while the fine velvet coating on the flexible rubber strip reduces friction between the flexible rubber strip and the surface of the charging gun head, thus mitigating the increased difficulty in inserting and removing the gun head protective sleeve 1 caused by the adhesive strip 7.

[0032] like Figure 2-5 As shown, in order to achieve a dual waterproof and dustproof design, a positioning plate 6 is provided on the inner side of the tail end of the gun head protective sleeve 1, and several insertion pins 4 are fixed on the positioning plate 6. Moreover, a waterproof rubber ring 406 is fixed on the outer side of each insertion pin 4. The waterproof rubber ring 406 includes a retaining ring 461 that engages with the annular groove 405. An inner rubber ring 462 and an outer rubber ring 463 are integrally formed on the outer side of the retaining ring 461. The inner rubber ring 462 is flat against the surface of the insertion pin 4, while the outer rubber ring 463 and the inner rubber ring 462 are inclined at 30-45 degrees to form a Y-shaped waterproof structure. The opening between the outer rubber ring 463 and the inner rubber ring 462 faces the rubber pad 5.

[0033] In order to avoid the pin structure at the end of the charging gun, each of its several plug pins 4 corresponds to a plug position at the end of the charging gun, and each plug pin 4 is a hollow cylindrical design.

[0034] like Figure 2-6 As shown, in order to allow the plug pins 4 to be disassembled and replaced, and to facilitate the subsequent installation of accessories such as charging gun sensors or switches through the plug pin positions, the tail end of each plug pin 4 is recessed to form an adapter groove 401. A positioning prism 402 is integrally formed in the center of the adapter groove 401, and a mounting post 403 is integrally formed at the middle of the tail end of the positioning prism 402. A T-shaped annular groove 405 with a circular cross-section is formed around the middle of each plug pin 4 to install a waterproof rubber ring 406. A rubber pad 5 is also provided between the positioning plate 6 and the tail end of the plug pin 4, with the side of the rubber pad 5 close to the plug pin 4 corresponding to the tail end of each plug pin 4. Each adapter groove 401 has an integrally formed washer 502 that matches the adapter groove 401. Each washer 502 has a clearance hole 501 at its center that fits on the outside of the positioning prism 402. The positioning plate 6 has a positioning hole 601 that matches the size of the positioning prism 402 at the tail end of each plug pin 4. The mounting post 403 at the tail end of the plug pin 4 slides through the sealing end of the gun head protective sleeve 1 and is screwed with a mounting cap 404. The mounting post 403 has a cylindrical design and the inner wall of the mounting post 403 has threads. The mounting cap 404 is a quick-release flat cap bolt design.

[0035] In the overall structural design, an adhesive strip 7 is set on the inner side of the gun head protective sleeve 1 near the opening end, which can effectively avoid obvious gaps between the gun head protective sleeve 1 and the outer side of the front end of the charging gun. In conjunction with the cylindrical plug pin 4 set inside the gun head protective sleeve 1, and the Y-shaped waterproof rubber ring 406 set on the outer side of the plug pin 4, the device has a waterproof effect far exceeding that of traditional charging gun protective covers. Moreover, the plug pin 4, together with the gun head protective sleeve 1, can also effectively improve the stability of the insertion and engagement between the rotating protective sleeve and the front end of the charging gun, ensuring that the waterproof effect is not easily interfered with by external forces.

[0036] Furthermore, each plug pin 4 can be independently disassembled and installed, providing ample room for future expansion by installing monitoring sensors and other accessories inside the gun head protective sleeve 1.

[0037] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
