Description

Technical Field

[0001] The present invention belongs to the technical field of distribution cabinets, and particularly relates to an integrated distribution cabinet for charging new energy vehicles. Background Art

[0002] With the rise of new energy vehicles in China, more and more consumers choose to purchase domestic new energy vehicles for daily use. Therefore, various supporting facilities for new energy vehicles are rapidly popularized across the country in a blooming manner. Among them, the most important one is the charging pile for new energy vehicles. Different from ordinary electrical appliances, new energy vehicle charging piles often come with dedicated distribution cabinets because the requirements for the power system during new energy vehicle charging, especially centralized fast charging, are much higher than those for ordinary household electricity. In some places where unified distribution cabinets for new energy vehicles are not yet equipped, consumers often need to purchase and configure integrated distribution cabinets by themselves. Such integrated distribution cabinets usually have a higher degree of integration with the charging piles and are more suitable for household use.

[0003] Most of the existing integrated distribution cabinets integrate the charging pile equipped with a charging gun into the distribution cabinet, which is more conducive to household installation after reducing the overall volume. To facilitate charging new energy vehicles, the integrated distribution cabinet is usually installed in an outdoor environment. When charging a new energy vehicle for a long time, in case of rain or snow, the rain or snow will inevitably drift into the connection position between the charging pile and the charging gun, thus affecting the charging behavior of the charging gun. Moreover, since many current new energy vehicles use high-voltage charging, the charging gun with water on the connection position may also pose a safety threat to users. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide an integrated distribution cabinet for charging new energy vehicles.

[0005] The technical solution adopted to solve the above technical problem is as follows: An integrated distribution cabinet for charging new energy vehicles, including a distribution cabinet body. The distribution cabinet body is divided into upper and lower parts. The upper part is a charging box, and the lower part is a distribution box. A charging gun and a charging wire are installed in the charging box. The charging wire is connected to the distribution box. A switch box door is hinged on the side wall of the charging box. A placing block is installed in the charging box. The charging gun is installed on the placing block. A movement cavity is opened at the bottom of the charging box. A movement rod is slidably connected in the movement cavity. A pushing mechanism for pushing the movement rod is installed in the placing block; A wire passing hole is formed at the bottom of the switch box door. A full baffle and a half baffle are arranged outside the wire passing hole. A through hole is formed in the side wall of the half baffle. The full baffle and the half baffle are in a horizontal state and a vertical state respectively, and are located on both sides of the wire passing hole. Through rods are fixedly arranged on the side walls of the full baffle and the half baffle. The through rods pass through the side wall of the switch box door. A protection box is installed inside the switch box door. The through rods pass through the side wall of the protection box and are provided with threaded grooves. An opening and closing mechanism for driving the threaded grooves is installed on the top of the protection box.

[0006] Through the above technical solution, a wire passing hole for facilitating the charging wire to pass through and a full baffle and a half baffle for blocking the wire passing hole are formed in the charging box of the integrated power distribution cabinet, so that the shielding state in front of the wire passing hole will change accordingly before and after the charging gun is pulled out. The full baffle and the half baffle will be located in front of the wire passing hole respectively to block it, which will neither affect the charging of the charging gun nor allow rain and snow from the outside to float into the charging box, thus better protecting the safety of the charging gun.

[0007] Further, side stoppers are respectively arranged on the side walls of both sides of the placing block, and the two side stoppers respectively abut against the side wall of the charging gun.

[0008] Through the above technical solution, a clamping block for clamping the charging gun can also be arranged on the side wall of the side stopper, so as to better clamp the charging gun. The arrangement of the side stopper can keep the charging gun in a vertical state, which is not only more convenient for the user to take out the charging gun, but also the muzzle of the charging gun is at a high position in the vertical state, and it is difficult for dust, rain and snow to enter it.

[0009] Further, the pushing mechanism includes an inclined block, a semi-circular block, a central rod, a rotating gear, a first bevel gear, a second bevel gear, a connecting rod, a driving gear and a moving rack. A placing cavity is formed in the placing block. The inclined block is slidably connected in the placing cavity. A notch is formed in the side wall of the placing block. The inclined block passes through the notch and abuts against the side wall of the charging gun. The central rod is rotatably connected to the side wall of the placing cavity. The semi-circular block is arranged on the central rod. One end side wall of the semi-circular block abuts against the side wall of the inclined block. A side torsion spring is arranged outside the central rod. A rotating tooth is arranged on the side wall of the semi-circular block. The rotating gear is rotatably connected to the side wall of the placing cavity. The first bevel gear is fixedly connected to the side wall of the rotating gear. The rotating gear meshes with the rotating tooth. The connecting rod movably passes through the bottom of the placing block. One end of the connecting rod is fixedly connected to the second bevel gear, and the other end is fixedly connected to the driving gear. The first bevel gear meshes with the second bevel gear. The driving gear is located in the moving cavity. The moving rack is fixedly arranged on the side wall of the moving rod. The moving rack meshes with the driving gear.

[0010] Through the above technical solution, when the charging gun is inserted into the placement block, the charging gun will push the inclined block into the placement cavity. The movement of the inclined block will drive the semi-circular block to rotate, compressing the side torsion spring. At the same time, due to the presence of the rotating teeth on the rotating semi-circular block, it will also drive the rotating gear to rotate. The first bevel gear arranged on the side wall of the rotating gear will drive the second bevel gear to rotate, thereby causing the moving rod to advance.

[0011] Furthermore, sliding rods are respectively arranged on the side walls of both sides of the inclined block, and sliding grooves are formed on the side wall of the placement cavity. The sliding rods are slidably connected in the sliding grooves.

[0012] Through the above technical solution, the cooperation between the sliding rod and the sliding groove can make the inclined block slide more stably in the placement cavity. Moreover, as can be seen from the figure, both the sliding rod and the sliding groove are inclined, so it can help the inclined block perform oblique movement.

[0013] Furthermore, the opening and closing mechanism includes a translation plate, two push rods and a plurality of telescopic springs. The two push rods respectively abut against the two threaded grooves. Two vertical grooves are formed on the top of the protective box. The two push rods respectively pass through the two vertical grooves and are fixedly connected to the bottom of the translation plate. The plurality of telescopic springs are respectively fixedly arranged between the side wall of the switch box door and the side wall of the translation plate.

[0014] Through the above technical solution, the setting of the telescopic spring enables the translation plate to have a tendency to drive the two push rods to move away from the switch box door. The push rods can only slide along the vertical grooves. And because the push rods abut against the threaded grooves, the moving push rods can drive the through rods to rotate, thereby changing the positions of the full baffle and the half baffle.

[0015] Furthermore, a fixed seat is arranged on the top of the protective box. A rotating rod is installed in the fixed seat. An S-shaped rod is arranged on the side wall of the rotating rod. A through groove is formed at the bottom of the S-shaped rod. A fixed rod is arranged in the through groove. A fixed block is fixedly arranged on the side wall of the translation plate away from the telescopic spring. The fixed rod passes through the side wall of the fixed block. A top seat is also arranged on the side wall of the switch box door. A bottom rod is arranged at the bottom of the top seat. A turntable is arranged at the bottom of the bottom rod. A top block is arranged at the bottom of the turntable. An inclined rod is arranged on the side wall of the turntable. One end of the inclined rod is rotatably connected to a telescopic rod. The other end of the telescopic rod is rotatably connected to a rotating rod. The other end of the rotating rod is rotatably connected to the side wall of the switch box door. A push rod is arranged at the top of the moving rod. The side wall of the push rod abuts against the connection positions of the telescopic rod and the rotating rod.

[0016] Through the above technical solution, the push rod arranged at the top of the moving rod can push the telescopic rod and the rotating rod, so that the inclined rod drives the turntable to rotate. The rotation of the turntable will cause the top block to squeeze the S-shaped rod to rotate around the rotating rod. Since the S-shaped rod is connected to the translation plate through the fixing block and the fixing rod, the rotation of the S-shaped rod will drive the translation plate to move towards the direction of the telescopic spring, thereby changing the positions of the full baffle and the half baffle.

[0017] Further, a top torsion spring is wound around the bottom rod. One end of the top torsion spring is fixedly connected to the side wall of the top seat, and the other end is fixedly connected to the side wall of the turntable.

[0018] Through the above technical solution, the force exerted by the top torsion spring on the turntable will make the turntable have a tendency to rotate, thereby ensuring that without external force, the top block will be in a state of squeezing the S-shaped rod, so that the half baffle is in front of the wire passing hole, and the full baffle will vacate the position of the wire passing hole.

[0019] Further, both ends of the top block are arc-shaped designs, and the center of the arc of the end of the S-shaped rod facing the top block faces away from the direction of the switch cabinet door.

[0020] Through the above technical solution, since the top block needs to squeeze the S-shaped rod, both ends of the top block need to be designed as arc-shaped for convenient squeezing. Moreover, the top block generally squeezes the S-shaped rod from the direction of the switch cabinet door, so the end of the S-shaped rod facing the top block is an arc-shaped design for convenient squeezing.

[0021] Further, an inclined groove is opened at the bottom of the charging box. The moving rod and the moving rack are both inclined. The push rod extends out of the inclined groove, and the end of the push rod facing the telescopic rod is arc-shaped.

[0022] Through the above technical solution, because the placement block for placing the charging gun is located on one side inside the charging box, and in order to facilitate the charging wire to pass through the switch cabinet door, the wire passing hole needs to be set in the middle of the switch cabinet door. Therefore, the horizontal positions of the placement block and the wire passing hole do not correspond. Therefore, in order to facilitate the push rod to push the telescopic rod and the rotating rod, the moving rod and the push rod need to move obliquely. Therefore, an inclined inclined groove is provided at the bottom of the charging box.

[0023] Through the above technical solution, the beneficial effects of the present invention are as follows: (1) By opening a wire passing hole in the charging box of the integrated power distribution cabinet for facilitating the charging wire to pass through, and a full baffle and a half baffle for blocking the wire passing hole in the present invention, the state of the wire passing hole will change accordingly before and after the charging gun is pulled out. When charging is required, the half baffle will block in front of the wire passing hole, which will neither affect the charging of the charging gun nor allow rain and snow from the outside to float into the charging box. When charging is not required, the charging gun is installed on the placement block. At this time, the full baffle blocks the wire passing hole and completely closes it, thereby better preventing rain and snow from entering the charging box. (2) The present invention uses a pure mechanical structure in the charging box to achieve the effect of baffle transformation. The pure mechanical design is not only simpler and easier to repair, but also can avoid the additional setting of a low-voltage circuit for driving inside the high-voltage power distribution cabinet of a new energy vehicle, thereby reducing the risk of damage to the power distribution cabinet. The transformation of the two baffles can prevent rain, snow, etc. from entering the inside of the charging box and affecting the safety of the charging gun. (3) The present invention is provided with side stoppers on both sides of the placing block respectively. At the same time, a clamping block for clamping the charging gun can also be provided on the side wall of the side stopper, so as to better clamp the charging gun. The setting of the side stopper can keep the charging gun in a vertical state, which is not only more convenient for the user to take out the charging gun, but also the muzzle of the charging gun is at a high position in the vertical state, and it is very difficult for dust, rain, snow, etc. to enter it. A clamping position for accommodating the charging gun head can also be provided inside the charging box to further ensure the safety of the charging gun. (4) As long as the switch cabinet door is opened, under the action of the top torsion spring, the half baffle will block in front of the wire passing hole. The perforation on the side wall of the half baffle facilitates the charging wire to pass through. If the charging gun has been taken out, the inclined block and the semi-circular block inside the placing block will rotate under the drive of the side torsion spring, and then the push rod will move to a position far away from the switch cabinet door in the inclined groove. At this time, when the switch cabinet door is closed, the position of the half baffle will not change. If the charging gun is placed on the placing block, due to the charging gun abutting against the inclined block, after a series of transmissions, the push rod will move to a position close to the switch cabinet door in the inclined groove. At this time, when the switch cabinet door is closed again, the push rod will abut against the connection position of the telescopic rod and the rotating rod, and then the full baffle and the half baffle will rotate synchronously, so that the full baffle moves to the front of the wire passing hole and plays a complete blocking effect on it.

Detailed implementation manners

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] As Figures 1 - 3 shown, this embodiment provides an integrated power distribution cabinet for charging new energy vehicles, including the main body 1 of the power distribution cabinet. The main body 1 of the power distribution cabinet is divided into upper and lower parts. The upper part is the charging box 2, and the lower part is the distribution box 3. A charging gun 4 and a charging cable 5 are installed in the charging box 2. The charging cable 5 is connected to the distribution box 3. A switch cabinet door 6 is hinged on the side wall of the charging box 2. A placing block 7 is installed in the charging box 2. The charging gun 4 is installed on the placing block 7. Side stop blocks 16 are respectively arranged on the side walls of both sides of the placing block 7. The two side stop blocks 16 respectively abut against the side wall of the charging gun 4. A clamping block for clamping the charging gun 4 can also be arranged on the side wall of the side stop block 16, so as to better clamp the charging gun 4. The arrangement of the side stop blocks 16 can keep the charging gun 4 in a vertical state, which is not only more convenient for the user to take out the charging gun 4, but also the muzzle of the charging gun 4 is at a high position in the vertical state, and it is difficult for dust, rain, snow, etc. to enter it.

[0028] Refer to Figure 4 With Figure 5, a movement cavity is provided at the bottom of the charging box 2, a movement rod 8 is slidably connected in the movement cavity, and a pushing mechanism for pushing the movement rod 8 is arranged in the placement block 7. The pushing mechanism includes an inclined block 17, a semi-circular block 18, a central rod 19, a rotating gear 20, a first bevel gear 21, a second bevel gear 22, a connecting rod 23, a driving gear 24, and a movement rack 25. A placement cavity is provided in the placement block 7, the inclined block 17 is slidably connected in the placement cavity, sliding rods 29 are respectively arranged on both side walls of the inclined block 17, and sliding grooves 30 are provided on the side wall of the placement cavity. The sliding rods 29 are slidably connected in the sliding grooves 30. The cooperation between the sliding rods 29 and the sliding grooves 30 can make the inclined block 17 slide more stably in the placement cavity, and as can also be seen from Figure 4 , both the sliding rods 29 and the sliding grooves 30 are inclined, so it can help the inclined block 17 to move obliquely. When the inclined block 17 is pushed back into the placement cavity by the charging gun 4, it will move obliquely along the sliding groove, thereby driving the semi-circular block 18 to rotate around the central rod 19.

[0029] A notch 26 is provided on the side wall of the placement block 7, the inclined block 17 passes through the notch 26 and abuts against the side wall of the charging gun 4. The central rod 19 is rotatably connected to the side wall of the placement cavity. The semi-circular block 18 is arranged on the central rod 19, and one end side wall of the semi-circular block 18 abuts against the side wall of the inclined block 17. A side torsion spring 27 is arranged outside the central rod 19. The force applied by the side torsion spring 27 to the semi-circular block 18 will make the semi-circular block 18 always maintain the state of abutting against the inclined block 17, and when the charging gun 4 is not placed on the placement block 7, it will push the inclined block 17 out of the notch 26. A rotating tooth 28 is arranged on the side wall of the semi-circular block 18. The rotating gear 20 is rotatably connected to the side wall of the placement cavity. The first bevel gear 21 is fixedly connected to the side wall of the rotating gear 20. The rotating gear 20 is engaged with the rotating tooth 28. The connecting rod 23 movably passes through the bottom of the placement block 7. One end of the connecting rod 23 is fixedly connected to the second bevel gear 22, and the other end is fixedly connected to the driving gear 24. The first bevel gear 21 is engaged with the second bevel gear 22. The driving gear 24 is located in the movement cavity. The movement rack 25 is fixedly arranged on the side wall of the movement rod 8. The movement rack 25 is engaged with the driving gear 24. When the charging gun 4 is inserted into the placement block 7, the charging gun 4 will push the inclined block 17 into the placement cavity. The movement of the inclined block 17 will drive the semi-circular block 18 to rotate, causing the side torsion spring 27 to be compressed. At the same time, due to the existence of the rotating tooth 28, the rotating semi-circular block 18 will also drive the rotating gear 20 to rotate. The first bevel gear 21 arranged on the side wall of the rotating gear 20 will drive the second bevel gear 22 to rotate, thereby making the movement rod 8 move forward.

[0030] Combined with Figure 1 , Figure 6 , Figure 7 and Figure 8As shown, a wire passing hole 9 is provided at the bottom of the switch box door 6, and a full baffle 10 and a half baffle 11 are arranged outside the wire passing hole 9. The effect of baffle transformation is achieved by using a pure mechanical structure in the charging box 2. The pure mechanical design is not only simpler and easier to repair, but also can avoid additionally setting a low-voltage circuit for driving inside the high-voltage new energy vehicle power distribution cabinet, thereby reducing the risk of damage to the power distribution cabinet body 1. The transformation of the two baffles can prevent rain and snow from entering the charging box 2 and affecting the safety of the charging gun 4. A perforation 12 is provided on the side wall of the half baffle 11. The full baffle 10 and the half baffle 11 are in a horizontal state and a vertical state respectively, and the full baffle 10 and the half baffle 11 are located on both sides of the wire passing hole 9. The setting of the perforation 12 enables the charging wire 5 to easily pass through the switch box door 6 without leaving more gaps, thereby preventing external rain and snow from entering the charging box 2.

[0031] If the charging gun 4 has been removed, the inclined block 17 and the semi-circular block 18 inside the placing block 7 will both rotate under the drive of the side torsion spring 27, thereby causing the push rod 47 to move to a position far away from the switch box door 6 in the inclined slot 49. At this time, the switch box door 6 is closed, and the position of the half baffle 11 will not change. If the charging gun 4 is placed on the placing block 7, due to the charging gun 4 re-abutting against the inclined block 17, after the reverse transmission of the above steps, the push rod 47 will move to a position close to the switch box door 6 in the inclined slot 49. At this time, when the switch box door 6 is closed again, the push rod 47 will abut against the connecting position of the telescopic rod 45 and the rotating rod 46, thereby causing the full baffle 10 and the half baffle 11 to rotate synchronously, causing the full baffle 10 to move in front of the wire passing hole 9, thereby achieving a complete shielding effect on it.

[0032] Through rods 13 are fixedly arranged on the side walls of the full baffle 10 and the half baffle 11. The through rods 13 pass through the side wall of the switch box door 6. A protective box 14 is installed inside the switch box door 6. The through rods 13 pass through the side wall of the protective box 14 and are provided with threaded grooves 15. An opening and closing mechanism for driving the threaded grooves 15 is installed on the top of the protective box 14. The opening and closing mechanism includes a translation plate 31, two push rods 32 and a plurality of telescopic springs 33. The two push rods 32 respectively abut against the two threaded grooves 15. Two vertical grooves 34 are provided on the top of the protective box 14. The two push rods 32 respectively pass through the two vertical grooves 34 and are fixedly connected to the bottom of the translation plate 31. A plurality of telescopic springs 33 are respectively fixedly arranged between the side wall of the switch box door 6 and the side wall of the translation plate 31. The setting of the telescopic springs 33 enables the translation plate 31 to have a tendency to drive the two push rods 32 to move away from the switch box door 6. The push rods 32 can only slide along the vertical grooves 34. Moreover, since the push rods 32 abut against the threaded grooves 15, the moving push rods 32 can drive the through rods 13 to rotate, thereby causing the full baffle 10 and the half baffle 11 to change positions.

[0033] A fixing seat 35 is arranged at the top of the protection box 14. A rotating rod 36 is installed in the fixing seat 35. An S-shaped rod 37 is arranged on the side wall of the rotating rod 36. A through groove is formed at the bottom of the S-shaped rod 37. A fixing rod 38 is arranged in the through groove. A fixing block 39 is fixedly arranged on the side wall of the translation plate 31 away from the telescopic spring 33. The fixing rod 38 passes through the side wall of the fixing block 39. A top seat 40 is also arranged on the side wall of the switch cabinet door 6. A bottom rod 41 is arranged at the bottom of the top seat 40. A turntable 42 is arranged at the bottom of the bottom rod 41. A top torsion spring 48 is wound around the bottom rod 41. One end of the top torsion spring 48 is fixedly connected to the side wall of the top seat 40, and the other end is fixedly connected to the side wall of the turntable 42.

[0034] In addition, combined with Figure 3 As shown, a top block 43 is arranged at the bottom of the turntable 42. Both ends of the top block 43 are designed in an arc shape. The center of the arc of one end of the S-shaped rod 37 facing the top block 43 faces away from the switch cabinet door 6. Since the top block 43 needs to squeeze the S-shaped rod 37, both ends of the top block 43 need to be designed in an arc shape for convenient squeezing. Moreover, the top block 43 generally squeezes the S-shaped rod 37 from the direction of the switch cabinet door 6. Therefore, one end of the S-shaped rod 37 facing the top block 43 is designed in an arc shape for convenient squeezing. And in the design process of the S-shaped rod 37, the upper half of the S-shaped rod 37 can be designed to be larger, so as to facilitate the squeezing and pushing of the top block 43. The force applied by the top torsion spring 48 to the turntable 42 will make the turntable 42 have a tendency to rotate. Thus, it is ensured that without external force, the top block 43 will be in a state of squeezing the S-shaped rod 37. As a result, the half baffle 11 is in front of the wire passing hole 9, and the full baffle 10 will vacate the position of the wire passing hole 9. And the elastic force of the top torsion spring 48 is greater than the elastic force of the telescopic spring 33. Therefore, the top torsion spring 48 can drive the turntable 42 to rotate and push the translation plate 31 to compress the telescopic spring 33.

[0035] Referring again to Figure 2 、 Figure 3 And Figure 5As shown in the figure, an inclined rod 44 is provided on the side wall of the turntable 42. The side wall of the inclined rod 44 is rotatably connected to a telescopic rod 45. The other end of the telescopic rod 45 is rotatably connected to a rotating rod 46. The other end of the rotating rod 46 is rotatably connected to the side wall of the switch box door 6. A push rod 47 is provided at the top of the moving rod 8. The side wall of the push rod 47 abuts against the connection positions of the telescopic rod 45 and the rotating rod 46. Therefore, when the push rod 47 moves forward, the included angle between the telescopic rod 45 and the rotating rod 46 will become larger. An inclined groove 49 is formed at the bottom of the charging box 2. Both the moving rod 8 and the moving rack 25 are inclined. The push rod 47 extends out from the inclined groove 49. One end of the push rod 47 facing the telescopic rod 45 is arc-shaped. Since the placement block 7 for placing the charging gun 4 is located on one side inside the charging box 2, and in order to facilitate the charging cable 5 to pass through the switch box door 6, the wire passing hole 9 needs to be set in the middle position of the switch box door 6. Therefore, the horizontal positions of the placement block 7 and the wire passing hole 9 do not correspond. Therefore, in order to facilitate the push rod 47 to push the telescopic rod 45 and the rotating rod 46, it is necessary to make the moving rod 8 and the push rod 47 move obliquely. Therefore, an inclined inclined groove 49 is provided at the bottom of the charging box 2.

[0036] The working principle of this embodiment is as follows. In the initial state, the charging gun 4 is installed on the placement block 7. At this time, the switch box door 6 is in the closed state. The push rod 47 is just in contact with the connection positions of the telescopic rod 45 and the rotating rod 46. The top block 43 at the bottom of the turntable 42 does not squeeze the S-shaped rod 37. At this time, the translation plate 31 is in a position far away from the switch box door 6 under the action of the telescopic spring 33. Therefore, the full baffle 10 blocks the wire passing hole 9, and the half baffle 11 is in a vertical state. When the user needs to charge a new energy vehicle, the staff needs to first open the switch box door 6. When opening the switch box door 6, the telescopic rod 45 and the rotating rod 46 lose the support of the push rod 47, and the turntable 42 will rotate under the drive of the top torsion spring 48 at the top. The rotating inclined rod 44 will also drive the telescopic rod 45 to rotate, so that the included angle between the telescopic rod 45 and the rotating rod 46 decreases. At the same time, the top block 43 at the bottom of the turntable 42 will squeeze the S-shaped rod 37. The squeezed S-shaped rod 37 will rotate around the rotating rod 36. Therefore, the fixed rod 38 provided at the other end of the S-shaped rod 37 will drive the fixed block 39 to move, and then the translation plate 31 will move towards the switch box door 6, compressing the telescopic spring 33. The two push rods 32 provided at the bottom of the translation plate 31 will slide in the vertical groove 34, and then the threaded groove 15 will drive the through rod 13 to rotate, so that the half baffle 11 and the full baffle 10 will rotate at the same time. The half baffle 11 rotates in front of the wire passing hole 9, and the full baffle 10 rotates to a vertical state. Then the user can remove the charging gun 4, and the charging cable 5 can pass through the through hole 12 of the half baffle 11, which not only does not affect the passage of the charging cable 5, but also can prevent rain and snow from entering the charging box 2 to the greatest extent. After charging is completed, the user first winds the charging cable 5 into the charging box 2, and then inserts the charging gun 4 back onto the placement block 7. The inclined block 17 in the notch 26 will be squeezed by the charging gun 4 and move. The semi-circular block 18 abutting against the side wall of the inclined block 17 will be driven to rotate. Since the rotating teeth 28 provided on the side wall of the semi-circular block 18 are engaged with the rotating gear 20, the rotation of the semi-circular block 18 will drive the rotating gear 20 to rotate. The first bevel gear 21 provided on the side wall of the rotating gear 20 will drive the second bevel gear 22 to rotate. The connecting rod 23 on the side wall of the second bevel gear 22 will drive the driving gear 24 to rotate. The moving rack 25 engaged with the driving gear 24 will drive the moving rod 8 to slide in the moving cavity. The push rod 47 provided on the top of the moving rod 8 will move to the position closest to the switch box door 6 in the inclined slot 49; Before closing the switch box door 6, there is still a semi-baffle 11 in front of the wire passing hole 9. After closing the switch box door 6, the push rod 47 will squeeze the connection position of the telescopic rod 45 and the rotating rod 46 again, so that the turntable 42 rotates in the reverse direction, so that the full baffle 10 and the semi-baffle 11 change positions, and the full baffle 10 returns to the front of the wire passing hole 9 again, providing a better protection effect for the inside of the charging cable 5.

[0037] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
