Description

Technical Field

[0001] This invention relates to the field of charging equipment technology, and in particular to a charging device for new energy vehicles. Background Technology

[0002] With the rapid development of the new energy vehicle industry, charging facilities, as key supporting equipment, are receiving increasing attention for their ease of use, safety, and environmental adaptability. Currently, common new energy vehicle charging equipment typically includes charging piles, charging cables, and charging heads. Users complete the charging operation by holding the charging head and inserting it into the vehicle's charging port. However, the protection measures for charging heads when not in use are insufficient. Most existing charging stations do not have a dedicated structure for storing or protecting charging heads, resulting in the charging heads being exposed to the external environment for a long time. This makes them susceptible to rain, dust, direct sunlight, and other factors, which can accelerate aging or cause electrical safety hazards. Especially in outdoor or semi-outdoor scenarios, water can easily enter the plug-in area during rain or snow, affecting the safety of subsequent use. Secondly, the charging heads are fixed in a relatively simple way. Most charging stations only use brackets or simple hooks to hang and store the charging heads, lacking a stable clamping and sealing structure. The charging heads are easily detached due to wind, vibration, or accidental contact, posing a risk of damage. At the same time, there is no effective sealing between the plug-in area and the charging station interface, making it difficult to achieve reliable waterproof and dustproof effects. Therefore, a new energy vehicle charging device is designed to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to solve the problems existing in the above-mentioned background technology and to propose a new energy vehicle charging device.

[0004] The technical problem to be solved by the present invention is to provide a new energy vehicle charging device to solve the problems of existing new energy vehicle charging devices.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a new energy vehicle charging device, including a charging pile, a charging cable, a charging head, a protective component and an n-shaped rain cover, wherein the charging cable is electrically connected to the lower side of the charging pile, the end of the charging cable is electrically connected to the charging head, and the protective component is fixedly installed on the upper side of the charging pile, and the n-shaped rain cover is sleeved on the protective component. The charging head includes a handle, a bent connecting part, and a plug-in part. The top of the handle is integrally formed with a bent connecting part, and the end of the bent connecting part is fixedly provided with a plug-in part. The protective assembly includes a vertical plate, a plug-in ring, an annular expansion groove, a sealing ring, and a handle clamping component. The plug-in ring is fixedly installed on the top of the vertical plate. An annular expansion groove is opened inside the plug-in ring facing the opening end. A sealing ring is embedded in the annular expansion groove. A handle clamping component is fixedly installed on the bottom of the vertical plate.

[0006] Preferably, the inner diameter of the insertion ring is equal to the inner diameter of the insertion part, and the diameter of the annular expansion groove is equal to the diameter of the bent connection part.

[0007] Preferably, when the plug portion is fully inserted into the plug ring, the bent connecting portion is inserted into the annular expansion groove near the plug portion, and at this time the bent connecting portion is tightly attached to the sealing ring.

[0008] Preferably, the handle clamping component includes a horizontal plate, a slot, a mounting slot, a return spring, and a locking block. The slot is provided in the center of the left end of the horizontal plate, and mounting slots are provided on both sides of the slot. A locking block is fixedly installed inside the mounting slot by a return spring. An unlocking component is also installed on the horizontal plate.

[0009] Preferably, the width of the slot is equal to the diameter of the handle, and the end of the slot away from the slot opening is in a semi-circular arc shape that matches the handle.

[0010] Preferably, the end of the card block away from the card slot opening has an arc shape that matches the handle portion, and the thickness component of the end of the card block facing the card slot opening is reduced.

[0011] Preferably, when the reset spring is in its naturally extended state, the end of the locking block facing the slot opening is completely inside the mounting slot, and at this time, the arc shape of the end of the locking block away from the slot opening is aligned with the semi-circular arc-shaped part of the slot away from the opening. When the reset spring is in its maximum compressed state, the locking block is completely inside the mounting slot.

[0012] Preferably, when the two locking blocks engage the handle portion with the slot away from the open end, the insertion portion is fully inserted into the insertion ring.

[0013] Preferably, the unlocking component includes an internal groove, a trapezoidal block, a pressing post, a sleeve spring, and a side groove. The mounting groove has an internal groove on its side facing the end near the slot opening. The trapezoidal block is slidably disposed in the internal groove. A pressing post is fixedly disposed at the left end of the trapezoidal block and passes through the left end of the horizontal plate. A sleeve spring is fixedly disposed between the pressing post, the left side of the internal groove, and the left side of the trapezoidal block. The left surface of the card block has a side groove.

[0014] Preferably, when the sleeve spring is in its naturally extended state, the trapezoidal block is completely in the inner groove, and the pointed part of the right end of the trapezoidal block is aligned with the side groove. When the pressing column is completely pressed into the horizontal plate, the trapezoidal block is completely inserted into the side groove, and after the trapezoidal block is completely inserted into the side groove, the locking block is completely embedded in the mounting groove. Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] In the above solution, by setting up a plug ring, annular expansion groove and sealing ring, when storing the charging head, the plug part of the charging head is aligned with the plug ring and inserted, so that the plug part is fully inserted into the plug ring. At this time, the bent connection part is in the annular expansion groove, and the sealing ring seals the gap between the annular expansion groove and the bent connection part, ensuring the protection of the plug part of the charging head by the plug ring and reducing the impact of rain, dust and other factors on the plug part.

[0016] In the above solution, an n-shaped rain cover is installed. The n-shaped rain cover can not only block rainwater and reduce rainwater corrosion of the charging head and protective components, but also block sunlight, slowing down the aging of the charging head and protective components and increasing their service life.

[0017] In the above solution, by providing a handle clamp, when the plug of the charging head is fully inserted into the plug ring, the handle is aligned with the opening end of the slot and enters the slot. The handle presses against the locking block, causing the locking block to move into the mounting groove. The return spring is in a compressed state until the handle is at the inner end of the slot. The return spring then pops the locking block out of the mounting groove. At this time, the locking block locks the handle in the inner end of the slot, ensuring the stability of the handle and preventing the charging head from falling due to strong winds. At this time, the plug is fully inserted into the plug ring, ensuring the stability of the plug inserted into the plug ring.

[0018] In the above solution, by setting an unlocking component, when it is necessary to remove the charging head, the pressing post is pressed into the inside of the horizontal plate. The pressing post drives the trapezoidal block to insert into the side groove on the card block. The sleeve spring is in a stretched state, and at this time the trapezoidal block drives the card block to move into the inside of the mounting groove. The return spring is in a compressed state until the card block is completely in the mounting groove, which makes it easy to remove the handle from the card groove, thereby making it easy to remove the plug part from the plug ring. After releasing the pressing post, under the action of the sleeve spring and the return spring, the trapezoidal block and the card block return to their original positions, which is convenient for subsequent use.

[0025] like Figures 1-6 As shown, an embodiment of the present invention provides a new energy vehicle charging device, including a charging pile 1, a charging cable 2, a charging head 3, a protective component and an n-shaped rain cover 7. The charging cable 2 is electrically connected to the lower side of the charging pile 1, and the charging head 3 is electrically connected to the end of the charging cable 2. The protective component is fixedly installed on the upper side of the charging pile 1, and the n-shaped rain cover 7 is sleeved on the protective component. The charging head 3 includes a handle 301, a bending connection 302 and a plug-in part 303. The top of the handle 301 is integrally formed with the bending connection 302, and the end of the bending connection 302 is fixedly provided with the plug-in part 303. The protective assembly includes a vertical plate 4, a plug-in ring 5, an annular expansion groove 501, a sealing ring 502, and a handle clamping component. The plug-in ring 5 is fixedly installed on the top of the vertical plate 4. An annular expansion groove 501 is opened inside the plug-in ring 5 facing the opening end. The sealing ring 502 is embedded in the annular expansion groove 501. The handle clamping component is fixedly installed on the bottom of the vertical plate 4.

[0026] In this embodiment, the inner diameter of the insertion ring 5 is equal to the inner diameter of the insertion part 303, and the diameter of the annular expansion groove 501 is equal to the diameter of the bent connection part 302.

[0027] In this embodiment, when the plug portion 303 is fully inserted into the plug ring 5, the bent connecting portion 302 is inserted into the annular expansion groove 501 near the plug portion 303, and at this time the bent connecting portion 302 is tightly attached to the sealing ring 502, ensuring the sealing of the charging head 3 inserted into the plug ring 5. By incorporating a plug ring 5, an annular expansion groove 501, and a sealing ring 502, when storing the charging head 3, the plug portion 303 on the charging head 3 is aligned with the plug ring 5 and inserted, ensuring that the plug portion 303 is fully inserted into the plug ring 5. At this time, the bent connecting portion 302 is placed inside the annular expansion groove 501, and the sealing ring 502 seals the gap between the annular expansion groove 501 and the bent connecting portion 302, ensuring that the plug ring 5 protects the plug portion 303 of the charging head 3 and reducing the impact of rainwater, dust, and other factors on the plug portion 303.

[0028] By incorporating an n-shaped rain cover 7, the rain cover 7 can not only block rainwater and reduce its erosion of the charging head 3 and protective components, but also block sunlight, slowing down the aging of the charging head 3 and protective components and increasing their service life.

[0029] In this embodiment, the handle clamping component includes a horizontal plate 6, a slot 601, a mounting slot 602, a reset spring 603, and a locking block 604. A slot 601 is provided in the center of the left end of the horizontal plate 6, and mounting slots 602 are provided on both sides of the slot 601. The locking block 604 is fixedly installed inside the mounting slot 602 by the reset spring 603. An unlocking component is also installed on the horizontal plate 6.

[0030] In this embodiment, the width of the slot 601 is equal to the diameter of the handle portion 301, and the end of the slot 601 away from the opening of the slot 601 is in a semi-circular arc shape that matches the handle portion 301.

[0031] In this embodiment, the end of the card block 604 away from the opening of the card slot 601 has an arc shape that matches the handle portion 301, and the thickness component of the end of the card block 604 facing the opening of the card slot 601 is reduced.

[0032] In this embodiment, when the reset spring 603 is in its naturally extended state, the end of the locking block 604 facing the opening of the slot 601 is completely inside the mounting groove 602, and at this time, the arc shape of the end of the locking block 604 away from the opening of the slot 601 is aligned with the semi-circular arc-shaped part of the slot 601 away from the opening. When the reset spring 603 is in its maximum compressed state, the locking block 604 is completely inside the mounting groove 602.

[0033] In this embodiment, when the two locking blocks 604 engage the handle 301 in the slot 601 away from the open end, the insertion part 303 is fully inserted into the insertion ring 5.

[0034] With the handle clamping part provided, when the plug part 303 of the charging head 3 is fully inserted into the plug ring 5, the handle part 301 aligns with the opening end of the slot 601 and enters the slot 601. The handle part 301 presses against the locking block 604, causing the locking block 604 to move into the mounting groove 602. The return spring 603 is in a compressed state until the handle part 301 is at the inner end of the slot 601. The return spring 603 pops the locking block 604 out of the mounting groove 602. At this time, the locking block 604 locks the handle part 301 in the inner end of the slot 601, ensuring the stability of the handle part 301 and preventing the charging head 3 from falling due to strong winds. At this time, the plug part 303 is fully inserted into the plug ring 5, ensuring the stability of the plug part 303 inserted into the plug ring 5.

[0035] In this embodiment, the unlocking component includes an internal groove 605, a trapezoidal block 606, a pressing post 607, a sleeve spring 608, and a side groove 6041. The side of the mounting groove 602 has an internal groove 605 facing the end near the opening of the slot 601. The trapezoidal block 606 is slidably disposed in the internal groove 605. The pressing post 607 is fixedly disposed at the left end of the trapezoidal block 606 and passes through the left end of the horizontal plate 6. The sleeve spring 608 is fixedly disposed between the left side of the internal groove 605 and the left side of the trapezoidal block 606. The left surface of the slot 604 has a side groove 6041.

[0036] In this embodiment, when the sleeve spring 608 is in its naturally extended state, the trapezoidal block 606 is completely in the inner groove 605, and the pointed part of the right end of the trapezoidal block 606 is aligned with the side groove 6041. When the pressing column 607 is completely pressed into the horizontal plate 6, the trapezoidal block 606 is completely inserted into the side groove 6041. After the trapezoidal block 606 is completely inserted into the side groove 6041, the locking block 604 is completely embedded in the mounting groove 602.

[0037] With the unlocking component in place, when the charging head 3 needs to be removed, the pressing post 607 is pressed into the horizontal plate 6. The pressing post 607 drives the trapezoidal block 606 to insert into the side groove 6041 on the locking block 604. The sleeve spring 608 is in a stretched state, and at this time, the trapezoidal block 606 drives the locking block 604 to move into the mounting groove 602. The return spring 603 is in a compressed state until the locking block 604 is completely in the mounting groove 602, making it easy to remove the handle 301 from the slot 601. This facilitates the removal of the insertion part 303 from the insertion ring 5. After releasing the pressing post 607, the trapezoidal block 606 and the locking block 604 return to their original positions under the elastic force of the sleeve spring 608 and the return spring 603, facilitating subsequent use.
