Specifically in the automotive industry, people are eager to pursue new engine technologies to replace traditional internal combustion engines. New energy vehicle technology is booming and its application is becoming increasingly widespread. In response to this trend, peripheral equipment related to new energy vehicles, such as charging guns and charging stations, has mushroomed, responding to rapidly growing market demand.

[0003] Most common charging station sockets on the market are equipped with protective doors to prevent foreign objects or users' fingers from accidentally entering the socket when the charging gun is not inserted, causing electric shock or damage to live parts. However, existing protective door mechanisms often fail to lock, meaning the door can be easily opened even when the charging gun is not inserted. This not only poses a safety hazard but also may affect the service life of the charging station. Utility Model Content

Furthermore, because the second sliding shafts on the left and right sides of the lower drive member are slidably connected within the second waist-shaped slot, when the second sliding shafts move downward, the second waist-shaped slot guides the protective door baffle to rotate about the rotation axis, causing the interference block at the upper end of the protective door baffle to rotate forward and separate from the lower end side of the protective door, thereby releasing the lock on the protective door. The first guide bevel guides the upper drive member, compressing the first spring and moving upward along the upper sliding groove. The first waist-shaped slot guides the two protective doors to rotate left and right about the rotation axis, causing them to rotate away from each other to open, allowing the charging gun to be directly inserted into the charging gun insertion hole. When the charging gun is removed, the upper drive member, acting under the elastic force of the first spring, translates downward to its initial position. The first sliding shaft, slidingly connected within the first waist-shaped slot, then drives the two protective doors to move in the opposite direction around the rotation axis again, allowing them to close again in front of the charging gun insertion hole. This effectively prevents users from accidentally opening the doors when the charging gun is not inserted. The lower drive member, also acting under the elastic force of the second spring, translates upward to its initial position. The second sliding shaft, slidingly connected within the second waist-shaped slot, then drives the two protective door baffles to move in the opposite direction around the rotation axis again to their initial position. The abutments on the upper ends of the two protective door baffles contact the lower side faces of the two protective doors, which are facing away from each other. The abutments lock the protective doors, effectively resolving the problem of the protective doors of existing charging station sockets not being able to lock. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0027] Example 1, as Figure 1-6 As shown, a charging pile socket body with a protective door mechanism includes a shell 1 and a front cover 2. A charging gun insertion hole 3 is provided in the middle of the shell 1. Rotation slots 4 are respectively provided on the left and right sides of the front surface of the shell 1. A rotating shaft 5 is provided at the upper end of the inner cavity of the rotation slot 4; an upper sliding slot 6 is provided above the front surface of the shell 1;

[0028] A protective door 8 is installed in each of the two rotating grooves 4. A rotating hole 81 is opened at the upper end of the protective door 8. The protective door 8 is rotatably connected to the rotating shaft 5 through the rotating hole 81. A first waist-shaped slot 82 is opened on the surface of the protective door 8; an upper driving member 9 is installed along the upper sliding groove 6 for sliding up and down. The upper surface of the upper driving member 9 abuts against the lower end of the first spring 10, and the upper end of the first spring 10 abuts against the upper wall of the inner cavity of the shell 1; a first sliding shaft 91 is provided on the inner side of the upper driving member 9, and the first sliding shaft 91 is slidably connected to the first waist-shaped slot 82. A first guide inclined surface 92 is provided at the lower front side of the upper driving member 9;

[0029] The front cover 2 is fixedly installed on the front side of the shell 1. A gun insertion port 21 corresponding to the charging gun insertion hole 3 is opened in the middle of the front cover 2. A cavity is formed between the front cover 2 and the shell 1. The protective door 8 and the upper drive part 9 are both located in the cavity. A rear cover 7 is installed on the rear side of the shell 1.

[0030] Working principle:

[0031] In the initial state, the two protective doors 8 are closed in front of the charging gun insertion hole 3. During use, the charging gun is first inserted through the gun insertion port 21 in the center of the front cover 2. It then contacts the front side of the upper driver 9. Then, a force is applied to the charging gun, causing it to press against the first guide bevel 92 on the front side of the upper driver 9. This guide action of the first guide bevel 92 compresses the upper driver 9 and causes it to move upward along the upper sliding groove 6. Because the first sliding shaft 91 on the rear side of the upper driver 9 is slidably connected to the first waist-shaped slot 82, the upward movement of the first sliding shaft 91, guided by the first waist-shaped slot 82, drives the two protective doors 8 to rotate left and right about the rotation axis 5, causing them to rotate away from each other to open. This moves the two protective doors 8 away from the front side of the charging gun insertion hole 3, allowing the charging gun to be directly inserted into the charging gun insertion hole 3.

[0032] When the charging gun is removed, the upper driving member 9 can be moved downward to its initial position by the elastic force of the first spring 10. Then, the first sliding shaft 91 can slide in the first waist-shaped slot 82, thereby driving the two protective doors 8 to move in the opposite direction around the rotation axis 5 again, and then the door surfaces of the two protective doors 8 can be closed again in front of the charging gun insertion hole 3. This effectively prevents the user from accidentally opening the door when the charging gun is not inserted.

[0033] Embodiment 2, as a further preferred embodiment of embodiment 1, a lower sliding groove 11 is provided at the lower portion of the front surface of the shell 1, and both side walls of the lower sliding groove 11 are provided with rotating slots 12, and both sides of the inner wall of the lower sliding groove 11 are provided with strip holes 13, and protective door stoppers 14 are installed on both sides of the inner cavity of the lower sliding groove 11, and the sides of the protective door stoppers 14 are provided with rotating shafts 141, and the rotating shafts 141 are rotatably connected in the rotating slots 12, and the protective door stoppers 14 moveably pass through the strip holes 13; a second waist-shaped slot 142 is provided on the surface of the protective door stopper 14, and an interference block 143 is provided at the upper end of the protective door stopper 14, and the interference block 143 movably interferes with the lower end side of the protective door 8;

[0034] A lower driving member 15 is installed along the inner edge of the lower sliding groove 11 for sliding up and down. The lower surface of the lower driving member 15 abuts against the upper end of the second spring 16, and the lower end of the second spring 16 abuts against the lower wall of the inner cavity of the shell 1; second sliding shafts 151 are provided on the left and right sides of the lower driving member 15, and the second sliding shafts 151 are slidably connected in the second waist-shaped slot 142. A second guide inclined surface 152 is provided above the front side surface of the lower driving member 15.

[0035] Therefore, when the charging gun is inserted through the gun insertion port 21 in the middle of the front cover 2, the charging gun will contact the front side of the lower driving member 15 before contacting the front side of the upper driving member 9. Then, by applying a force to the charging gun, the charging gun is pressed onto the second guide inclined surface 152 on the front side of the lower driving member 15, thereby driving the lower driving member 15 to compress the second spring 16 and move downward along the lower sliding groove 11 through the inclined surface guiding effect of the second guide inclined surface 152; and because the second sliding shafts 151 on the left and right sides of the lower driving member 15 are slidably connected to the second waist-shaped slot 142, when the second sliding shaft 151 moves downward, it can be guided by the second waist-shaped slot 142 to drive the protective door baffle 14 to rotate around the rotating shaft 141, so that the resistance block 143 at the upper end of the protective door baffle 14 rotates forward to separate from the lower end side of the protective door 8, and the lock of the protective door 8 is released. When the charging gun is then pushed further toward the charging gun insertion hole 3, the upper driving member 9 described in Example 1 can be used to drive the two protective doors 8 to rotate away from each other, thereby realizing the opening action of the protective doors 8, so that the charging gun can be directly inserted into the charging gun insertion hole 3.

[0036] When the charging gun is pulled out, the two protective doors 8 are closed again in front of the charging gun insertion hole 3, and the lower driving member 15 is also moved upward to the initial position by the elastic force of the second spring 16. Then, the second sliding shaft 151 is slidably connected in the second waist-shaped slot 142, thereby driving the two protective door baffles 14 to move in the opposite direction around the rotation axis 141 to the initial position again, so that the upper ends of the two protective door baffles 14 contact the lower end side surfaces of the two protective doors 8 that are away from each other, thereby achieving the locking effect of the protective doors 8 through the interference blocks 143. This effectively solves the problem that the protective doors of existing charging pile sockets cannot be locked.

[0037] In the third embodiment, as a further preferred embodiment of the second embodiment, a second limiting strip groove 111 is vertically provided in the lower sliding groove 11, and a second sliding rib 153 is provided on the inner side of the lower driving member 15. The second sliding rib 153 is slidably connected in the second limiting strip groove 111. The second sliding rib 153 is slidably connected in the second limiting strip groove 111, thereby limiting the sliding direction of the lower driving member 15 and preventing the lower driving member 15 from deflecting during sliding.

[0038] Example 4, as a further preferred embodiment of Example 2, features a second spring slot 112 vertically defined on the inner wall of the lower sliding groove 11. The second spring 16 is positioned within this slot. A spring pressure plate 154 is provided on the inner side of the lower driving member 15. The upper end of the second spring 16 abuts against the lower surface of the spring pressure plate 154. The second spring slot 112 defines the position of the second spring 16, preventing it from tilting within the lower sliding groove 11. Furthermore, the presence of the spring pressure plate 154 abutting against the second spring 16 ensures uniform force on the lower driving member 15.

[0039] In the fifth embodiment, as a further preferred embodiment of the first embodiment, a first limiting strip groove 61 is vertically provided on the inner wall of the upper sliding groove 6, and a first sliding rib 93 is provided on the inner side of the upper driving member 9. The first sliding rib 93 is slidably connected within the first limiting strip groove 61. The first sliding rib 93 is slidably connected within the first limiting strip groove 61, thereby limiting the sliding direction of the upper driving member 9 and preventing the upper driving member 9 from deflecting during sliding.

[0040] Example 6, as a further preferred embodiment of Example 1, features a first spring slot 62 vertically defined in the inner wall of the upper sliding groove 6, with the first spring 10 positioned within the slot. A pressure plate 94 is provided on the side of the upper drive member 9, with the lower end of the first spring 10 abutting against the upper surface of the pressure plate 94. The first spring slot 62 defines the position of the first spring 10, preventing it from tilting within the upper sliding groove 6. Furthermore, the pressure plate 94 abutting against the first spring 10 ensures uniform force on the upper drive member 9.

[0041] Embodiment 7, as a further preferred embodiment of Embodiment 2, includes a baffle plate limiting rib and a spring limiting rib provided on the inner side of the front cover 2. The baffle plate limiting rib contacts the outer surface of the protective door baffle 14, and the spring limiting rib contacts the first spring 10 and the second spring 16. The baffle plate limiting rib and the spring limiting rib further limit the protective door baffle 14, the first spring 10, and the second spring 16.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents.
