It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0024] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0025] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0026] According to the first aspect of the present utility model, Figure 1 As shown, a charging seat with a protective structure 13 is provided, including a charging seat shell, a conductive terminal and a plug-in terminal, the charging seat shell is provided with at least one charging interface 1, the charging interface 1 has a accommodating cavity 11, the bottom of the accommodating cavity 11 is provided with a plurality of socket sleeves 12 protruding axially, the conductive terminal is arranged in the socket sleeve 12, and the free end of the socket sleeve 12 is provided with a protective structure 13 closing the end face opening thereof, the protective structure 13 is constructed as follows: in the process of the plug-in terminal being inserted into the socket sleeve 12 via the protective structure 13 and plugging with the conductive terminal to complete the electrical connection, elastic deformation is generated to form a through hole for the plug-in terminal to pass through.

[0027] With the development of automobile technology, charging products have become very popular. Charging seats, as an indispensable and important part of electric vehicles, have naturally received great attention. As the current carrier of electric vehicles, the safety issue of charging seats has always been a concern of people. Since the opening of the charging interface 1 of the charging seat is large, fingers can be inserted into it, which poses a safety hazard. At the same time, the charging interface 1 is exposed to the external environment and cannot be isolated from wind and sand. If small particles of sand and gravel enter it, the charging gun will be plugged in and out for a long time, which will cause damage to the conductive terminal plating and create a safety hazard.

[0028] The charging stand of the present design adds a cover curtain type protection structure 13 at its charging interface 1, which not only solves the safety hazard problem of the existing charging stand due to the large opening of the charging interface 1, into which fingers can be inserted, but also solves the problem that the charging interface 1 is exposed to the external environment and cannot be isolated from wind and sand, and small particles of sand and stone enter the charging interface, causing the conductive terminal plating to wear and cause leakage during the plugging and unplugging of the charging gun. It can also extend the service life of the charging stand terminal. The present structure is simple and is also conducive to mass production.

[0029] In some embodiments, Figure 1 As shown, the protective structure 13 is a circular sheet structure that completely covers the inner diameter of the end face opening, the outer edge of the circular sheet structure is connected to the inner wall of the socket sleeve 12, and a cross cut 131 is provided in the center of the circular sheet structure.

[0030] The protective structure 13 of the circular sheet structure is simple in structure, easy to process, and low in cost. Its outer edge is connected to the inner wall of the socket sleeve 12 to form a whole with a stable structure. The cross cut 131 opened at the center is used to form an elastic deformation when the plug-in terminal is inserted into the socket sleeve 12 to form a through hole for the plug-in terminal to pass through.

[0031] In some embodiments, Figure 1 As shown, the cross cuts 131 divide the circular sheet structure into a plurality of elastic cover curtains, and during the process of inserting the plug terminal into the socket sleeve 12, the elastic cover curtains are deformed and bent into the socket sleeve 12 to form the through hole.

[0032] The cross cut 131 divides the circular sheet structure into a plurality of independent elastic cover curtains or an integral protective structure 13 formed by a plurality of elastic cover curtains with separated free ends and connected edges. When the charging seat is not charging, the circular sheet structure covers the end face opening of the socket tube 12 to prevent mud and sand from entering. During charging, the insertion of the plug-in terminal into the socket tube 12 drives the elastic cover curtain to deform and bend into the socket tube 12 to form a through hole for it to pass through and electrically connect with the conductive terminal.

[0033] In some embodiments, Figure 1 As shown, the cross section of the cross cut 131 is in the shape of a cross or a cross.

[0034] The cross-shaped or cross-shaped cross cut 131 is convenient for processing and is also convenient for forming a through hole for the plug-in terminal to pass through when the plug-in terminal is inserted into the socket 12 .

[0035] In some embodiments, the distance between the plug-in end of the conductive terminal and the end surface of the free end is greater than the radius of the circular sheet structure.

[0036] As the plug-in terminal is inserted into the socket sleeve 12, the protective structure 13 will be elastically deformed from the cross opening to form a through hole for the plug-in terminal to be inserted. During the elastic deformation of the protective structure 13, it gradually adheres to the inner wall of the socket sleeve 12 and approaches the plug-in end of the conductive terminal. The distance between the end face of the plug-in end of the conductive terminal and the free end is greater than the radius of the circular sheet structure, so that the conductive terminal and the protective structure 13 do not contact or interfere with each other in the socket sleeve 12, and sufficient space is provided for the insertion of the plug-in terminal, which is convenient for the plug-in electrical connection between the plug-in terminal and the conductive terminal.

[0037] In some embodiments, the maximum outer diameter of the cross cutout 131 is greater than or equal to the diameter of the plug-in terminal, and less than or equal to the inner diameter of the socket sleeve 12 .

[0038] The maximum outer diameter of the cross cut 131 is greater than or equal to the diameter of the plug-in terminal, which facilitates the plug-in terminal to pass through the cross cut 131 and prevents the plugging force of the plug-in terminal from damaging the integrity of the protective structure 13 from the cross cut 131. The maximum outer diameter of the cross cut 131 is less than or equal to the inner diameter of the socket sleeve 12 because the outer edge of the circular sheet structure is connected to the inner wall of the socket sleeve 12 due to the structure.

[0039] In some embodiments, the circular sheet structure has a thickness of 1 mm to 2.5 mm.

[0040] When the thickness of the circular sheet structure is less than 1 mm, the overall structure is thin and weak, and it is easy to be damaged during repeated insertion of the plug-in terminal. When the thickness of the circular sheet structure is greater than 2.5 mm, it is not conducive to processing and forming due to the high cost and thick thickness. In addition, during the insertion of the plug-in terminal, the blocking force of the protective structure 13 is enhanced and it is not easy to produce elastic deformation, which makes it difficult for the plug-in terminal to enter the socket tube 12. Under the action of the plug-in force, the cross cut 131 of the protective structure 13 and the outer wall of the plug-in terminal are easily scratched. When the thickness of the circular sheet structure is 1 mm-2.5 mm, the plug-in terminal is easy to enter the socket tube 12 from the cross cut 131, and both are not easily damaged. Therefore, the inventor prefers that the thickness of the circular sheet structure is 1 mm-2.5 mm.

[0041] In some embodiments, the width of the cross cut 131 is 0.1 mm-0.2 mm.

[0042] The design of the curtain-type protection structure 13 of the charging interface 1 of the present structure is not only to avoid the potential safety hazard of fingers being inserted into the charging interface 1 of the charging seat due to its large opening, but also to isolate the charging interface 1 from wind and sand when it is exposed to the external environment, prevent small particles of sand and stone from entering it, and reduce the risk of wear of the inner plating of the conductive terminal and the outer plating of the plug-in terminal due to sand and stone during the plugging and unplugging of the charging gun, thereby eliminating potential safety hazards and extending the overall service life of the charging seat. When the width of the incision gap of the cross cut 131 is less than 0.1mm, the cross cut 131 is subjected to the processing and forming process. The influence of technology is not conducive to the processing of the cross cut 131. When the cut gap width of the cross cut 131 is greater than 0.2mm, since the diameter of fine sand and gravel is between 0.2-2mm, the cut width gap is too large and cannot prevent fine sand and gravel from entering the socket 12. The protective structure 13 does not have a protective effect. Only when the cut gap width of the cross cut 131 is 0.1mm-0.2mm, the cross cut 131 is conducive to processing, and the protective structure 13 can also effectively block small particles of sand and gravel. Therefore, the inventor chooses the cut gap width of the cross cut 131 to be 0.1mm-0.2mm.

[0043] In some embodiments, the charging seat shell is made of hard rubber, the protective structure 13 is made of soft rubber, and the protective structure 13 is formed integrally with the end face opening by a two-color injection molding process.

[0044] Double-color injection molding refers to injecting the material of the charging seat shell and the material of the protective structure 13 into the same set of molds, so that the injection-molded charging seat is formed of two materials, thereby improving the integrity, aesthetics and overall assembly performance of the charging seat.

[0045] In some embodiments, the material of the protective knot is rubber, and the protective structure 13 is connected to the inner wall of the end opening by hot melt welding, cold welding or solvent welding.

[0046] Hot-melt welding is to heat the protective structure 13 to the softening point to make it liquid, and then bond it to the inner wall of the end opening to form a whole. The heat source used in this method can be flame, hot air or electric heating. Its advantage is that it can quickly and firmly connect the rubber parts.

[0047] Cold welding is to pressurize the protective structure 13 on the end opening and connect them together by adding adhesive. Its advantages are simple operation and no need to control temperature.

[0048] Solvent welding is a method of dissolving the protective structure 13 and the end face opening together using a solvent and then drying them to connect the two. It has the advantages of fast welding speed, the ability to connect complex shapes, and the ability to connect thin rubber parts.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
