[0007] The left and right sides above the front surface of the base body are respectively fixedly connected to a rotating shaft, and a protective door is respectively provided on the left and right sides of the front surface of the base body, and the protective door movably covers the front surface of the charging gun socket, and a rotating hole is provided at the upper end of the protective door, and the protective door is rotatably connected to the rotating shaft through the rotating hole, and an arc-shaped slot is provided on the surface of the protective door; an upper slide groove is provided above the rear side surface of the front cover, and a driving slider is connected to the upper slide groove for sliding up and down, and the upper surface of the driving slider is abutted against the lower end of the first spring, and the upper end of the first spring is abutted against the upper wall of the front cover; a sliding shaft is provided on the rear side surface of the driving slider, and the sliding shaft is slidably connected in the arc-shaped slot hole, and a first guide inclined surface is provided below the front side surface of the driving slider;
[0008] A sliding groove is provided at the lower part of the rear side surface of the front cover, and a positioning slider is connected to the inner edge of the sliding groove for sliding up and down, and the lower surface of the positioning slider is abutted against the upper end of the second spring, and the lower end of the second spring is abutted against the lower wall of the front cover; a cavity is provided on the rear side surface of the positioning slider, and a lock tongue is rotatably connected in the cavity, and a torsion spring mounting shaft is provided under the lock tongue, and a torsion spring is sleeved on the surface of the torsion spring mounting shaft, and the two torsion arms of the torsion spring are respectively abutted against the lock tongue and the positioning slider, and a claw is provided at the lower part of the rear side surface of the lock tongue, and the claw cooperates with the outer side surface of the lower end of the protective door; the upper end of the claw protrudes above the positioning slider.

[0012] The present invention provides a new energy vehicle charging pile socket with an integrated multi-self-locking protective door mechanism. It has the following beneficial effects: in the initial state, the driving slider is subjected to the elastic force of the first spring, so that the driving slider is located at the lowest position of the upper slide groove. At this time, the sliding connection of the sliding shaft on the side of the driving slider in the arc-shaped slot makes the door surfaces of the two protective doors closed in front of the charging gun insertion hole, thereby effectively avoiding the possibility of the user accidentally opening the door when the charging gun is not inserted. In addition, the positioning slider is also subjected to the elastic force of the second spring, so that the positioning slider is located at the highest position of the lower slide groove, and the lock tongue is also subjected to the elastic force of the torsion spring, so that the claw at the upper end of the lock tongue rotates toward the positioning slider. At this time, the two claws can be used to limit the left and right sides of the lower ends of the two protective doors. Thus, the locking effect of the protective door is achieved by locking the two claws. This effectively avoids the possibility of the user accidentally opening the door when the charging gun is not inserted.
[0013] When the charging gun is inserted, the end of the charging gun contacts the lock tongue, applying a thrust that causes the tongue to rotate about the pin. Simultaneously, the end of the charging gun contacts the front side of the positioning slider. The second guide bevel guides the positioning slider, compressing the second spring and moving it downward along the lower sliding groove. This causes the two claws at the lower end of the rear side of the lock tongue to separate from the protective door, unlocking the protective door. The first guide bevel then guides the driving slider, compressing the first spring and moving it upward along the upper sliding groove. The waist-shaped slot guides the two protective doors to rotate left and right around the rotation axis, causing them to rotate away from each other to open. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] 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.
[0024] Example 1, as Figure 1-6 As shown, a new energy vehicle charging pile socket with an integrated multi-self-locking protective door mechanism includes a base body 1, a charging gun socket 2 is provided in the middle of the base body 1, a front cover 3 is fixedly installed on the front side of the base body 1, and a gun insertion port 31 corresponding to the charging gun socket 2 is opened in the middle of the front cover 3, and a rear cover 15 is fixedly installed on the rear side of the base body 1;
[0025] The left and right sides above the front surface of the base body 1 are respectively fixedly connected with a rotating shaft 4, and the left and right sides of the front surface of the base body 1 are respectively provided with a protective door 5, which movably covers the front surface of the charging gun socket 2, and a rotating hole 51 is provided at the upper end of the protective door 5. The protective door 5 is rotatably connected to the rotating shaft 4 through the rotating hole 51, and an arc-shaped slot 52 is provided on the surface of the protective door 5; an upper slide groove is provided above the rear side surface of the front cover 3, and a driving slider 6 is connected to the upper slide groove for sliding up and down. The upper surface of the driving slider 6 is abutted against the lower end of the first spring 7, and the upper end of the first spring 7 is abutted against the upper wall of the front cover 3; a sliding shaft 61 is provided on the rear side surface of the driving slider 6, and the sliding shaft 61 is slidably connected in the arc-shaped slot 52, and a first guide inclined surface 62 is provided at the lower front side surface of the driving slider 6;
[0026] A lower sliding groove is provided at the bottom of the rear side of the front cover 3, and a positioning slider 8 is connected to the lower groove for sliding movement. The lower surface of the positioning slider 8 abuts against the upper end of the second spring 9, and the lower end of the second spring 9 abuts against the lower wall of the front cover 3. A cavity is provided at the rear side of the positioning slider 8, and a lock tongue 10 is rotatably connected to the cavity. Specifically, pin holes are provided on the left and right side walls of the cavity at the rear side of the positioning slider 8. Pins 16 are provided on the left and right sides of the lock tongue 10, and the pins 16 are rotatably connected to the pin holes. A torsion spring mounting shaft 11 is provided below the lock tongue 10, and a torsion spring 12 is sleeved on the surface of the torsion spring mounting shaft 11. The two torsion arms of the torsion spring 12 abut against the lock tongue 10 and the positioning slider 8 respectively. Two claws 13 are provided at the bottom of the rear side of the lock tongue 10, and the two claws 13 respectively cooperate with the outer side surfaces of the lower ends of the two protective doors 5; the upper ends of the claws 13 protrude above the positioning slider 8.
[0027] Working principle:
[0028] In the initial state, the driving slider 6 is subjected to the elastic force of the first spring 7, causing the driving slider 6 to be located at the lowest position of the upper slide groove. At this time, the sliding connection of the sliding shaft 61 on the side of the driving slider 6 within the arc-shaped slot 52 causes the door surfaces of the two protective doors 8 to be closed in front of the charging gun insertion hole 3. In addition, the positioning slider 8 is also subjected to the elastic force of the second spring 9, causing the positioning slider 8 to be located at the highest position of the lower slide groove, and the lock tongue 10 is also subjected to the elastic force of the torsion spring 12, causing the claw 13 at the upper end of the lock tongue 10 to rotate toward the positioning slider 8. At this time, the two claws 13 can be used to limit the left and right sides of the lower ends of the two protective doors 5, so that the lower ends of both protective doors 5 are limited to the position between the two claws 13. Therefore, by locking the two claws 13, the protective doors 5 are locked.
[0029] When the charging gun is inserted from the gun insertion port 31 of the front cover 3, the end of the charging gun will first contact the lock tongue 10, thereby giving the lock tongue 10 a thrust, causing the lock tongue 10 to rotate around the pin 16. At the same time, the end of the charging gun will also contact the front side of the positioning slider 8. The second guide slope 17 above the front side of the positioning slider 8 guides the positioning slider 8 to compress the second spring 9 and move downward along the sliding groove, thereby separating the two claws 13 at the lower end of the rear side of the lock tongue 10 from the protective door 5, thereby releasing the lock of the protective door 5. The charging gun is then pushed further toward the charging gun receptacle 2, causing the protein of the charging gun to contact the front side of the driving slider 6. At this time, the first guide slope 62 guides the driving slider 6 to compress the first spring 7 and move upward along the upper sliding groove. Since the sliding shaft 61 on the rear side of the driving slider 6 is slidably connected to the waist-shaped slot 52, when the sliding shaft 61 moves upward, the waist-shaped slot 52 can be used to guide the two protective doors 5 to rotate left and right around the rotating shaft 4, so that the two protective doors 5 rotate away from each other to achieve the opening action, and then the door surfaces of the two protective doors 5 are away from the front side of the charging gun socket 2, so that the charging gun can be directly inserted into the charging gun socket 2.
[0030] When the charging gun is removed, the driving slider 6 is forced downward by the elastic force of the first spring 7 to its initial position. The sliding shaft 61 then slides within the arcuate slot 52, causing the two protective doors 5 to move in the opposite direction around the rotation axis 4, closing the doors 5 in front of the charging gun receptacle 2. This effectively prevents users from accidentally opening the doors when the charging gun is not inserted. Furthermore, the positioning slider 8 is again acted upon by the elastic force of the second spring 9, causing it to move upward to its initial position. The locking tongue 10 is also acted upon by the elastic force of the torsion spring 12, causing the claws 13 at its upper end to rotate toward the positioning slider 8. At this point, the two claws 13 again retain the left and right sides of the lower ends of the two protective doors 5. By locking the two claws 13, the protective doors 5 are locked, effectively preventing users from accidentally opening the doors when the charging gun is not inserted.
[0031] Embodiment 2, as a further preferred embodiment of embodiment 1, a sealing gasket 14 is installed on the front side of the front cover 3. The sealing gasket 14 can effectively prevent dust and moisture from entering the interior of the socket, ensuring the sealing and safety of the socket.
[0032] In Example 3, as a further preferred embodiment of Example 1, an open slot is provided in the middle of the upper surface of the positioning slider 8, and the upper end of the lock tongue 10 is movably mounted in the open slot. The open slot allows the upper end surface of the lock tongue 10 to be exposed above the positioning slider 8, so that when the charging gun is inserted, the end of the charging gun can directly and effectively contact the upper front side surface of the lock tongue 10.
[0033] 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. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
