Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a new energy vehicle charging pile that is convenient for fixing a charging gun. Background Art

[0002] A charging station is a device that replenishes the energy of electric vehicles, similar to a gas pump at a gas station. Installed in public buildings (such as charging stations, shopping malls, and public parking lots) and residential parking lots, it can adjust the voltage and current to charge various models of electric vehicles. The input of the charging station is directly connected to the AC power grid, and the output is equipped with a charging plug for charging the electric vehicle.

[0003] Existing charging piles for new energy vehicles offer weak protection for the charging gun. The charging gun is typically plugged into the charging pile, resulting in poor securing. This makes it susceptible to damage from human impact and falling from the pile, rendering the charging pile incapable of recharging the new energy vehicle. Furthermore, the charging gun, a charging device in existing charging piles, is exposed to air, where dust easily accumulates, causing it to stick to the gun nozzle and shortening its service life. Summary of the Invention

[0004] The purpose of the present invention is to provide a new energy vehicle charging pile that is convenient for fixing a charging gun, so as to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A new energy vehicle charging pile that is convenient for fixing a charging gun, comprises a pile body, a placement groove for placing the charging gun is provided on the pile body, a self-locking part is provided in the pile body, the self-locking part comprises two symmetrically arranged locking blocks rotatably connected to the placement groove, the two locking blocks are hemispherical, both of the two locking blocks are connected to a transmission member, and a locking groove corresponding to the position of the locking blocks is provided on the charging gun; two symmetrically arranged dust covers are also slidably connected to the pile body, the two dust covers extend into the placement groove and abut against each other to prevent dust, a sealing part is provided on the side of the dust covers that are close to each other, and the two dust covers are connected to the transmission member through a connecting part.

[0007] Furthermore, the sealing member includes convex strips and grooves respectively provided on two surfaces of the two dust covers close to each other, a sealing strip is provided in the groove, and the convex strip presses the sealing strip to seal the placement groove.

[0008] Furthermore, the transmission part includes a slide plate slidably connected to a slide groove on the pile body, racks are provided on both sides of the slide plate, and each rack is meshed with a transmission gear, the transmission gear is rotatably connected to the pile body, and the transmission gear is fixedly connected to the locking block through a rotating rod, the rotating rod is rotatably connected to the pile body, one end of the slide plate extends out of the pile body, and also includes a reset part for resetting the slide plate.

[0009] Furthermore, the reset portion includes a reset spring fixedly arranged between the inner wall of the slide groove and the end of the slide plate.

[0010] Furthermore, the connecting part includes a connecting rod fixedly connected to the dust cover, the connecting rod is slidably connected to the pile body, a positioning rod is provided at the end of the connecting rod, the positioning rod extends into the positioning groove on the slide, and the positioning rod is slidably connected to the positioning groove, and the positioning groove is arranged at an angle.

[0011] Furthermore, a connecting block is rotatably connected to the positioning rod, and the connecting block is slidably connected to the positioning groove.

[0012] Furthermore, the charging gun is provided with cover grooves corresponding to the two dust covers.

[0013] Furthermore, a protective plate is rotatably connected to the pile body, and the protective plate covers a protective groove on the outer surface of the pile body, and the protective groove is communicated with the placement groove.

[0014] In the above technical solution, the present invention provides a new energy vehicle charging pile that is convenient for fixing the charging gun, which has the following beneficial effects:

[0015] 1. Through the self-locking part, when the charging gun is inserted into the placement slot, the charging gun contacts the locking block and causes the locking block to rotate, so that the charging gun passes through the locking block. The rotation of the locking block drives the transmission part to move, and the movement of the transmission part drives the two dust covers to move away from each other through the connecting part, so that the charging gun can pass through the dust cover. When the charging gun is fully inserted into the placement slot, the transmission part resets, thereby resetting the locking block and locking the charging pile by cooperating with the lock slot, thereby avoiding the problem of the charging gun being damaged due to falling due to external force, and improving the protection ability of the charging pile for the charging gun.

[0016] 2. Through the provided transmission parts, when the charging gun needs to be pulled out, the user presses the transmission parts to disengage the lock block from the lock slot, and the dust cover also disengages from the charging gun. The user can directly pull out the charging gun. After the charging gun is pulled out, the transmission parts automatically reset and the two dust covers automatically close, thereby forming a sealed protection for the placement slot, preventing external dust from entering the placement slot while the charging gun is charging the electric vehicle, effectively improving the dustproof ability of the charging pile, and thereby increasing the service life of the charging gun.

[0037] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0038] See also Figure 1-10 , a new energy vehicle charging pile for fixing a charging gun 120, includes a pile body 100, the pile body 100 is provided with a placement groove 110 for placing the charging gun 120, the pile body 100 is provided with a self-locking part 200, the self-locking part 200 includes two symmetrically arranged locking blocks 210 rotatably connected to the placement, the two locking blocks 210 are hemispherical, the two locking blocks 210 are connected to the transmission member 300, and the charging gun 120 is provided with a locking groove 220 corresponding to the position of the locking block 210; the pile body 100 is also slidably connected to two symmetrically arranged dust covers 600, the two dust covers 600 extend into the placement groove 110 and abut against each other to prevent dust, the dust covers 600 are provided with a sealing member 500 on the side close to each other, and the two dust covers 600 are connected to the transmission member 300 through the connecting part 400.

[0039] When the charging gun 120 is inserted into the placement slot 110, the charging gun 120 contacts the locking block 210 and causes the locking block 210 to rotate, so that the charging gun 120 passes through the locking block 210. The rotation of the locking block 210 drives the transmission member 300 to move. The transmission member 300 moves through the connecting part 400 to drive the two dust covers 600 to move away from each other, so that the charging gun 120 can pass through the dust covers 600. When the charging gun 120 is fully inserted into the placement slot 110, the transmission member 300 resets, thereby resetting the locking block 210, and by cooperating with the locking slot 220, the charging pile is locked, thereby avoiding the problem of the charging gun 120 being damaged due to falling due to external force, thereby improving the protection ability of the charging pile for the charging gun 120.

[0040] When the charging gun 120 needs to be pulled out, the user presses the transmission part 300 to disengage the locking block 210 from the locking slot 220, and the dust cover 600 also disengages from the charging gun 120. The user can directly pull out the charging gun 120. After the charging gun 120 is pulled out, the transmission part 300 automatically resets and the two dust covers 600 automatically close, thereby forming a sealed protection for the placement slot 110, preventing external dust from entering the placement slot 110 while the charging gun 120 is charging the electric vehicle, effectively improving the dustproof ability of the charging pile, and thereby improving the service life of the charging gun 120.

[0041] Furthermore, the sealing member 500 includes a ridge 510 and a groove 520 respectively provided on two surfaces of the two dust covers 600 close to each other. A sealing strip 530 is provided in the groove 520 . The ridge 510 presses the sealing strip 530 to seal the placement groove 110 .

[0042] Furthermore, the transmission member 300 includes a slide plate 310 that is slidably connected to a chute on the pile body 100. Racks 320 are provided on both sides of the slide plate 310. Each rack 320 is meshed with a transmission gear 330. The transmission gear 330 is rotatably connected to the pile body 100. The transmission gear 330 is fixedly connected to the locking block 210 via a rotating rod 340. The rotating rod 340 is rotatably connected to the pile body 100. One end of the slide plate 310 extends out of the pile body 100 and includes a reset portion for resetting the slide plate 310. The reset portion includes a reset spring 350 (not shown) fixedly disposed between the inner wall of the chute and the end of the slide plate 310. A pressing plate can be provided at the end of the slide plate 310 for ease of use.

[0043] The locking block 210 rotates through the rotating rod 340 to drive the transmission gear 330 to rotate, and the two transmission gears 330 rotate through the rack 320 to drive the slide 310 to move. The movement of the slide 310 compresses the return spring 350 and drives the dust cover 600 to move away from each other through the connecting part 400.

[0044] Furthermore, the connecting portion 400 includes a connecting rod 410 fixedly connected to the dust cover 600, the connecting rod 410 is slidably connected to the pile body 100, and a positioning rod 420 is provided at the end of the connecting rod 410. The positioning rod 420 extends into the positioning groove 430 on the slide plate 310, and the positioning rod 420 is slidably connected to the positioning groove 430, and the positioning groove 430 is arranged at an angle.

[0045] The movement of the slide plate 310 drives the positioning groove 430 to move synchronously. Since the positioning rod 420 is limited by the sliding of the pile body 100, the movement of the positioning groove 430 drives the positioning rod 420 to move, and the movement of the positioning rod 420 drives the movement of the dust cover 600. By controlling the inclination angle of the positioning groove 430, the dust cover 600 can be moved in a direction away from each other.

[0046] Furthermore, a connecting block 440 is rotatably connected to the positioning rod 420, and the connecting block 440 is slidably connected to the positioning groove 430. The connecting block 440 can further improve the sliding stability of the positioning rod 420 and the slide plate 310.

[0047] Furthermore, the charging gun 120 is provided with a cover groove 130 corresponding to the two dust covers 600 . When the charging gun 120 is fully inserted into the placement slot 110, the locking block 210 is in the locking slot 220 to lock the charging gun 120. Since the dust cover 600 abuts against the outer shell of the charging gun 120, the slide plate 310 cannot be completely reset, that is, the locking block 210 is partially abutted against the locking slot 220. Therefore, in order to further improve the locking ability of the pile body 100 on the charging gun 120, a cover groove 130 is provided on the outer surface of the charging gun 120, so that the dust cover 600 can be closer to each other. On the one hand, the locking block 210 can increase the contact area with the locking slot 220, thereby achieving a better locking effect. On the other hand, the cooperation between the dust cover 600 and the cover groove 130 forms a secondary locking of the charging gun 120, that is, the charging gun 120 is doubly locked by the locking block 210 and the dust cover 600, thereby further improving the locking effect of the pile body 100 on the charging gun 120.

[0048] Furthermore, a protective plate 140 is rotatably connected to the pile body 100. The protective plate 140 covers a protective groove 150 on the outer surface of the pile body 100, which is in communication with the placement groove 110. Under the action of gravity, the protective plate 140 automatically adheres to the protective groove 150, thereby forming a first layer of protection for the placement groove 110 while the charging gun 120 is charging the electric vehicle. This prevents dust, rain, and snow from entering the protective groove 150, thereby indirectly extending the service life of the pile body 100 and the charging gun 120.

[0049] Working principle:

[0050] When the charging gun 120 is inserted into the placement slot 110, the charging gun 120 contacts the locking block 210 and causes the locking block 210 to rotate, so that the charging gun 120 passes through the locking block 210. The locking block 210 rotates through the rotating rod 340 to drive the transmission gear 330 to rotate. The two transmission gears 330 rotate through the rack 320 to drive the slide 310 to move. The movement of the slide 310 compresses the return spring 350, and the slide 310 moves through the positioning slot 430 to drive the positioning rod 420 to move. The movement of the positioning rod 420 drives the dust cover 600 to move away from each other, so that the charging gun 120 can pass through the dust cover 600. When the charging gun 120 is fully inserted into the placement groove 110, the slide plate 310 moves in the opposite direction under the action of the return spring 350, so that the locking block 210 extends into the locking groove 220, and the dust cover 600 extends into the cover groove 130, forming a double locking of the pile body 100 on the charging gun 120, effectively improving the protection capability of the charging pile on the charging gun 120.

[0051] When the charging gun 120 needs to be pulled out, the user presses the slide plate 310 to disengage the locking block 210 from the locking slot 220 and the dust cover 600 from the cover slot 130. The user can then directly pull out the charging gun 120. After the charging gun 120 is pulled out, the transmission part 300 automatically resets under the action of the reset spring 350, and the two dust covers 600 automatically close, thereby forming a sealed protection for the placement slot 110.

[0052] The present invention enables the charging gun 120 to be automatically doubly locked after being inserted into the placement slot 110; and during the period when the charging gun 120 is pulled out, the dust cover 600 and the protective plate 140 can form a double barrier to prevent external dust, rain and snow from entering the placement slot 110, greatly improving the protection capability of the charging gun 120.

[0053] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
