Description

Technical Field

[0001] This utility model belongs to the field of new energy vehicle parts technology, specifically relating to a charging and distribution cover for a new energy vehicle. Background Technology

[0002] In the daily use of new energy vehicles, the charging port cover, as a key component protecting the charging port, is increasingly becoming a prominent issue affecting user experience due to its design flaws. Traditional charging port covers often use a design where the cover is directly attached to the charging port. This requires the cover to be completely removed during charging, and users, in a rush to charge, may easily forget to leave the cover at the charging location. This not only leaves the charging port unprotected, but the existing connection method between the charging port cover and the vehicle's charging location also has significant shortcomings. Most covers connect to the vehicle body using a soft plastic strip. However, due to the range characteristics of new energy vehicles, users need to charge almost daily, subjecting the soft plastic strip to repeated bending and stretching. The fatigue resistance of soft plastic is limited, and under high-frequency use, it is prone to aging and cracking, ultimately leading to the plastic strip breaking and detaching from the charging port cover. Utility Model Content

[0003] The purpose of this utility model is to provide a charging and distribution cover for new energy vehicles to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a charging and distribution cover for a new energy vehicle, comprising:

[0005] The charging port socket is fixedly installed at the vehicle's charging port location, and its cavity is used to accommodate the charging pins.

[0006] The aluminum top cover is slidably fitted into the cavity of the charging port socket. It is movably connected to the charging port socket via a fixed tension rod, enabling it to be pulled out and lowered for charging and to prevent loss.

[0007] A rubber round pad is installed on the inner wall of the aluminum top cover to contact the surface of the charging pins and provide insulation and protection.

[0008] The cleaning component is integrated into the bottom of the inner cavity of the aluminum top cover. During the reciprocating pulling of the aluminum top cover, it pushes and pulls to clean the dust on the charging feet inside the charging port socket.

[0009] Preferably, a positioning through hole is provided on one side of the surface of the charging port holder, and the charging port holder is installed in the charging port installation position of the new energy vehicle. One end of the positioning through hole is connected to the charging port installation position to avoid the risk of the top cover falling off due to the shaking of the connecting parts.

[0010] Preferably, one end of the fixed tension rod passes through the positioning through hole and is fixed to one side of the fixing block, one end of the fixing block is fixed to one side of the aluminum top cover, and the other end of the fixed tension rod is provided with a telescopic limit block, which not only prevents the top cover from completely detaching to prevent loss, but also can withstand high-frequency bending to avoid breakage.

[0011] Preferably, the outer surface of the aluminum top cover is covered with a rubber outer layer, which is used to allow the aluminum top cover to be inserted into the charging port socket and fit against the inner wall of the charging port socket for dust prevention and insulation. The elastic deformation of the rubber can fill the gaps, enhance the dust and water prevention effect, and at the same time block the risk of electrical conductivity from metal contact.

[0012] Preferably, the cleaning component protects the rubber ring, which is fixed to the inner wall of the aluminum cover with adhesive. After the aluminum cover is inserted, the rubber ring is located outside the charging pins in the charging port socket. No additional cleaning tools are needed. As the cover moves, the rubber ring can wrap around the outside of the pins, initially preventing dust from adhering.

[0013] Preferably, the inner wall of the rubber ring is uniformly provided with rubber brush heads, and the rubber brush heads are used to repeatedly pull and clean the dust in the charging slot of the charging port socket, so as to avoid the charging efficiency being affected by poor dust contact.

[0014] Preferably, the outer side of the aluminum top cover is provided with an outwardly protruding strip block, and push-pull blocks are provided on the middle of both sides of the strip block to allow the aluminum top cover to rotate and reciprocate within the charging port socket cavity. The protruding strip block and push-pull blocks provide a force point for the hand, conforming to the gripping habit, and making the pulling and rotating of the top cover easier.

[0015] Preferably, the aluminum top cover has a cylindrical insert sleeve extending to one side, the cleaning component is disposed at one end of the inner cavity of the insert sleeve, and a rubber outer layer covers the outer surface of the insert sleeve, so as to ensure that the insert sleeve is in close contact with the inner wall of the charging port socket.

[0016] Preferably, when the aluminum top cover is pulled out, the fixed tension rod moves accordingly, and after the aluminum top cover is fully pulled out of the charging port socket, the fixed tension rod moves downward so that the charging gun can be inserted into the charging port socket to charge the new energy vehicle.

[0017] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0018] The aluminum top cover is movably connected to the charging port socket via a fixed tension rod, replacing the traditional separate cover design. When the aluminum top cover is pulled out and lowered for charging, it remains connected to the charging port socket via the fixed tension rod, preventing the top cover from being lost due to negligence during charging and ensuring it does not detach from the vehicle body, thus reducing the risk of part loss.

[0019] By adopting a connection structure that combines a fixed tension rod with a fixing block and a telescopic limit block, the traditional soft plastic strip has been replaced. The material and structural design of the fixed tension rod can withstand high-frequency stretching and movement, and has stronger fatigue resistance. This effectively solves the problem of soft plastic strips being prone to aging, cracking, and breakage due to daily charging of new energy vehicles, extending the service life of the top cover and ensuring the stability of the connection.

[0020] The rubber outer layer covering the aluminum top cover allows it to fit tightly against the inner wall when inserted into the charging port socket, achieving good dustproof and insulation effects. At the same time, the cleaning component integrated into the bottom of the inner cavity of the aluminum top cover uses the rubber brush head on the rubber ring to push and pull to clean the dust inside the charging port socket during the reciprocating pulling process.

[0028] 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.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0030] Example 1, please refer to Figure 1-4 This utility model provides a technical solution: the charging and distribution cover for new energy vehicles presented in this embodiment integrates structure and function. The charging port holder 1, as the basic support component of the entire device, is made of high-quality engineering plastic using injection molding. Its cavity shape and dimensions are precisely calculated to achieve a high degree of matching with common charging plugs, ensuring stable accommodation of the charging plugs. It is firmly fixed to the preset installation position of the vehicle's charging port by four high-strength bolts, remaining flush with the vehicle body surface after installation, thus not affecting the vehicle's appearance and ensuring stability during use. On one side of the holder, a through-hole 7 is provided, which communicates with the charging port installation cavity of the vehicle body, providing a stable and smooth channel for the movement of the tension rod 4, ensuring that the tension rod does not jam or shift when moving within it.

[0031] The aluminum top cover 2 is made of 6061 aluminum alloy, a material with excellent mechanical properties, and is processed through precision stamping. This material is not only lightweight, reducing the additional load on the vehicle, but also structurally rigid, effectively resisting collisions and compressions during daily use. To enhance its performance, the outer surface of the top cover is coated with a rubber outer layer 9 using a high-temperature vulcanization process. The thickness of this rubber outer layer is controlled between 0.5 and 1 mm, forming an elastic buffer barrier. When the aluminum top cover 2 is inserted into the charging port holder 1, the rubber outer layer 9 deforms due to its elasticity, fitting tightly against the inner wall of the holder, with the gap between them controlled within 0.1 mm. This not only successfully prevents external dust, moisture, and other impurities from entering the cavity, protecting the charging pins from contamination and corrosion, but also avoids direct metal-to-metal contact between the aluminum top cover 2 and the charging port holder 1, thereby eliminating the risk of electrical conductivity and greatly improving safety during use.

[0032] A cylindrical insert sleeve 13 extends from one side of the aluminum top cover 2. The inner diameter of the sleeve is precisely machined to match the dimensions of the charging port socket 1 cavity, ensuring a tight fit during assembly. The cleaning component 6 is firmly fixed to the end of the insert sleeve 13 cavity with a high-strength adhesive, forming an integrated structure of the cover, sleeve, and cleaning component. This structure allows the cleaning component 6 to move synchronously with the top cover, ensuring stable cleaning performance.

[0033] The fixed connection system is crucial for ensuring the anti-loss function of the top cover. It consists of a fixed tension rod 4, a fixing block 3, and a telescopic limit block 8. The fixed tension rod 4 is made of 304 stainless steel, which has excellent corrosion resistance and wear resistance. The rod has a diameter of 5mm and is chrome-plated to further enhance its wear resistance and oxidation resistance, extending its service life. One end of the tension rod passes through the positioning through hole 7 and is fixedly connected to the fixing block 3 by welding. The weld is polished to ensure the connection is firm and smooth. The fixing block 3 is rigidly connected to the side of the aluminum top cover 2 by two countersunk screws. The countersunk screw design prevents the screw heads from protruding from the surface, avoiding interference with operation. The telescopic limit block 8 has a spring-loaded latch structure inside. When the tension rod is pulled out to its maximum stroke, the spring-loaded latch automatically pops out and locks, limiting the displacement to within 10-15cm. This travel range has been tested and verified multiple times. It provides enough space for charging operations, making it easy to insert and remove the charging gun, while the extension rod keeps the top cover connected to the base, fundamentally solving the problem of traditional detachable top covers being easily lost.

[0034] In terms of ease of operation, the aluminum top cover 2 features an outwardly protruding strip 11 with a height of 3mm, making it easy for users to hook their fingers around it. Two push-pull blocks 12 extend outward from the center of both sides of the strip 11. These blocks feature a symmetrical curved design, perfectly conforming to ergonomic principles and matching the grip angle of the fingers. Users can easily pull the top cover back and forth and rotate it 180° by simply pinching the push-pull blocks 12 with their thumb and forefinger. The operation is effortless and convenient, even for users with less strength.

[0035] The cleaning function relies on the synergistic action of the rubber ring 14 and the rubber brush head 10. The rubber ring 14 is made of nitrile rubber, a material with excellent aging resistance, which possesses good elasticity and wear resistance, enabling it to withstand long-term reciprocating friction. Within the inner ring, 20-30 rubber brush heads 10 are evenly distributed, positioned at a 45° angle. The specially treated bristles are soft and resilient. When the user inserts or removes the top cover, these brush heads penetrate 0.5-1 cm into the charging slot, cleaning away accumulated dust through reciprocating friction. Experimental data shows that this cleaning method reduces manual cleaning needs by over 90%, significantly alleviating the user's maintenance burden.

[0036] The rubber pad 5 is made of insulating rubber with a Shore hardness of 60. It is precisely adhered to the inner wall of the aluminum cover 2 at the position corresponding to the charging pin. When the cover is closed, the rubber pad 5 forms a flexible contact with the surface of the charging pin. This contact method not only avoids direct metal-to-metal collisions, reduces pin wear, and extends its service life, but also significantly enhances the insulation protection level of the entire device, reaching IP67 level. Even when used in humid environments, it can effectively prevent leakage accidents.

[0037] Example 2:

[0038] Please see Figure 5-6 This utility model provides a technical solution: a charging and distribution cover for a new energy vehicle, comprising:

[0039] The aluminum top cover 2 adopts a circular plate structure with a diameter matching the charging port base 1 and a thickness of 3-5mm. A neodymium iron boron magnetic block 19 is embedded in the upper part of the outer surface, which can form a stable attraction with the micro iron plate 17 preset on the surface of the charging port base 1. A pulling force of 5-8N is required for a single separation, which ensures a tight fit for daily use and makes it easy to open.

[0040] The fixing system adopts a matching structure of limiting column 16 and through hole 15: a limiting column 16 with a diameter of 8mm is welded to one side of the surface of the charging port base 1, and a limiting block with a diameter of 12mm is provided at the end of the column. A through hole 15 with a corresponding diameter is opened on the fixing block 3 on one side of the aluminum top cover 2. The column and the through hole adopt a clearance fit, allowing the top cover to slide along the axis of the column and rotate 360°. When charging is required, the user can lift the top cover to separate the magnetic block 19 from the micro iron piece 17, and then slide it down along the column to the lowest point. At this time, the position of the top cover is lower than the charging plane of the charging port base 1, completely avoiding the insertion path of the charging gun and solving the spatial interference problem of the traditional flip-type structure.

[0041] In terms of sealing and protection, a trapezoidal sealing ring 18 is embedded at the contact edge between the circular aluminum top cover 2 and the charging port socket 1. The ring is made of EPDM rubber and can generate a compression of 0.3mm in the suction state, forming an effective sealing barrier with a dustproof rating of IP6K9K. The fixing block 3 and the aluminum top cover 2 are integrally die-cast to avoid structural loosening caused by welding stress. The surface of the limiting column 16 is blackened to enhance rust resistance and ensure stable operation in environments ranging from -40℃ to 80℃.

[0042] This embodiment uses magnetic attraction instead of mechanical locking, which simplifies the operation steps while retaining the core function of preventing loss. It also ensures that the aluminum top cover is always connected to the limiting column 16 through the fixing block 3. Experimental tests show that after 10,000 insertion and removal cycles, the connection structure does not loosen or break, and the service life is effectively improved compared to traditional plastic strips.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
