Description

Technical Field

[0001] This invention belongs to the field of charging pile technology, and more specifically, it relates to a vehicle-mounted anti-interference low electromagnetic radiation charging pile. Background Technology

[0002] Charging piles function similarly to gas pumps at gas stations. They can be fixed to the ground or walls and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: regular charging and fast charging. Users can use a specific charging card to swipe on the human-machine interface provided by the charging pile to perform operations such as selecting the charging method, charging time, and printing cost data. The charging pile display screen can display data such as charging amount, cost, and charging time.

The take-up roller has a connection hole through which the cable extends out of the receiving cavity.

[0011] In one possible implementation, the locking assembly includes a socket, a rod, a first locking block, a second locking block, and a first spring. The socket is located on the housing, and the rod is located on the cover. The rod is inserted into the socket, and a slot is provided on the side wall of the socket. The first locking block is slidably disposed on the rod, and is used to extend out of the rod and retract into the rod. The rod has a locking groove. The second locking block is slidably disposed in the socket, and a first spring is provided between the second locking block and the bottom surface of the socket. When the rod is fully inserted into the socket, the second locking block is inserted into the locking groove, and the second locking block pushes the first locking block into the slot.

[0012] In one possible implementation, a connecting platform is provided on one side of the locking groove, and a second spring is provided between the connecting platform and the first locking block. When the second spring is in its natural state, the first locking block is housed in the insert rod. The first locking block has an inclined surface, which is arranged obliquely from the end near the first spring to the end away from the first spring, from the axis away from the locking groove to the axis near the locking groove. When the first locking block is housed in the insert rod, the end of the inclined surface away from the axis of the locking groove is flush with the side wall of the second locking block. When the insert rod is inserted into the insertion hole and the first spring is in its natural state, the second locking block is inserted into the locking groove.

[0013] In one possible implementation, the insertion rod is provided with an unlocking hole, which includes a large-diameter section and a small-diameter section. The axis of the small-diameter section is not colinear with the axis of the large-diameter section. The unlocking hole is connected to the locking groove. The unlocking component includes a large-diameter rod and a small-diameter rod. The diameter of the large-diameter rod is the same as that of the large-diameter section, and the diameter of the small-diameter rod is the same as that of the small-diameter section. The large-diameter section is provided with a positioning groove, and the large-diameter rod is provided with a positioning block. When the large-diameter rod is inserted into the large-diameter section and the positioning block is inserted into the positioning groove, the small-diameter rod is inserted into the small-diameter section, and the length of the small-diameter rod is greater than the length of the small-diameter section.

[0014] In one possible implementation, the charging gun is provided with a protective block, the top of which is located on one side of the charging end of the charging gun. The protective block is provided with a sealing groove, and a sealing frame is rotatably provided in the sealing groove. The sealing frame is L-shaped and has a cover plate. A torsion spring is provided between the sealing frame and the side wall of the sealing groove. When the torsion spring is in its natural state, the cover plate covers the charging end of the charging gun. The cover plate is used to release the seal on the charging end due to the rotation of the sealing frame.

[0015] In one possible implementation, the detection mechanism includes a button on the cover plate, a second button on one end of the charging gun, and a control device in the mounting cavity.

[0031] To make the technical problems to be solved, the technical solutions, and the beneficial effects 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 intended to limit the present invention.

Based on this concept, some specific forms and arrangements of connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be fully described. However, under the premise that those skilled in the art understand the concept of the present invention, they can implement the above-mentioned specific forms and arrangements in a well-known manner.

[0033] When a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0034] The terms “length”, “width”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inner”, “outer”, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0035] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0036] The present invention will now describe the vehicle-mounted anti-interference low electromagnetic radiation charging pile provided by the present invention.

[0037] Please refer to the following: Figure 1 and Figure 2 The vehicle-mounted anti-interference low electromagnetic radiation charging pile includes a housing 1, a cover 3, and an unlocking component 4. The housing 1 is made of electromagnetic shielding plastic and has an installation cavity 101 inside. The installation cavity 101 contains components for charging, and the housing 1 has an opening. The cover 3 is made of electromagnetic shielding plastic and covers the opening. A locking component is provided between the cover 3 and the housing 1.

[0038] The beneficial effects of the vehicle anti-interference low electromagnetic radiation charging pile provided in this embodiment are as follows: Compared with the prior art, the vehicle anti-interference low electromagnetic radiation charging pile provided in this embodiment can effectively reduce the leakage of electromagnetic radiation generated inside the charging pile by setting a shell 1, and the shell 1 is made of electromagnetic shielding plastic, so as to prevent the charging pile from affecting the surrounding electromagnetic environment. At the same time, it is also used to prevent the surrounding electromagnetic environment from affecting the charging pile, making the use of the charging pile safer.

[0039] Based on the above design concept, the vehicle-mounted anti-interference low electromagnetic radiation charging pile of the present invention also includes a detection mechanism, a winding mechanism 2, and an unlocking component 4. The detection mechanism is located on the charging gun 102 and is used to detect whether the charging gun has been removed from the vehicle. The winding mechanism is located inside the mounting cavity 101 and is connected to the detection mechanism. The winding mechanism can receive the detection signal from the detection mechanism, and when the charging gun 102 is removed from the vehicle, the winding mechanism winds up the cable. The unlocking component 4 is used to unlock the locking assembly. Because of the detection mechanism and the winding mechanism 2, the cable can be automatically wound up when charging is complete, preventing damage to the charging pile. Furthermore, in practical applications, to prevent loss, the unlocking component 4 is held by the operator.

[0040] like Figure 3 As shown, the winding mechanism 2 of the present invention includes two mounting plates 201, a winding roller 202 and a drive assembly. The mounting plates 201 are spaced apart in the mounting cavity 101. The winding roller 202 is rotatably disposed between the two mounting plates 201. The winding roller 202 is connected to the winding roller 202 and is used to wind or unwind the cable 103 due to rotation. The drive assembly is connected to the winding roller 202 and is used to drive the winding roller 202 to rotate.

[0041] When the take-up roller 202 rotates, it is used to wind the cable 103 onto the take-up roller 202 to facilitate the take-up of the cable 103. At the same time, it raises the charging gun 102 to a high position to prevent the user from forgetting to take up the charging gun 102 when charging is completed, and the charging gun 102 will be damaged if it is left on the ground.

[0042] Specifically, in this embodiment, the interval between the two mounting plates 201 is greater than the length of the take-up roller 202. One mounting plate 201 is provided with a through hole, and the other mounting plate 201 is provided with a threaded hole. A pivot rod 203 is provided at each end of the take-up roller 202. One pivot rod 203 is provided with a thread on its side wall. The threaded pivot rod 203 is screwed into the threaded hole, and the other pivot rod 203 is inserted into the through hole, so that the take-up roller 202 can move between the two mounting plates 201. When the cable 103 is wound, the cable 103 is used to wrap around the position of the take-up roller 202 where the cable 103 is not wrapped.

[0043] This configuration allows the cable 103 to be evenly wound on the take-up roller 202 without overlapping on the take-up roller 202. This prevents the cable 103 from becoming tangled on the take-up roller 202 and affecting the unwinding of the cable 103, making the vehicle-mounted anti-interference low electromagnetic radiation charging pile of the present invention easier to use.

[0044] As a preferred embodiment, a first limiting ring is provided on a pivot rod 203, and a second limiting ring is provided on the take-up roller 202. The drive assembly includes a mounting frame, a drive motor 206, a drive gear 207, and a driven gear 208. The mounting frame is U-shaped and includes two vertical plates 204 and a horizontal plate 205 disposed between the two vertical plates 204. A first pivot hole is provided on one vertical plate 204, and a first limiting groove is provided on the side wall of the first pivot hole. A second pivot hole is provided on the other vertical plate 204, and a second limiting groove is provided on the side wall of the second pivot hole.

[0045] A pivot rod 203 is inserted into a first pivot hole, and a first limiting ring is inserted into a first limiting groove. A take-up roller 202 is inserted into a second pivot hole, and a second limiting ring is inserted into a second limiting groove. The side wall of the horizontal plate 205 abuts against the inner wall of the housing 1, so that the mounting frame can move with the movement of the take-up roller 202. A drive motor 206 is mounted on the horizontal plate 205. A drive gear 207 is connected to the power output end of the drive motor 206. A driven gear 208 is mounted on one of its pivot rods 203. The drive gear 207 meshes with the driven gear.

[0046] The mounting bracket is designed to provide mounting space for the drive motor 206. The engagement of the first limiting groove and the first limiting ring, as well as the engagement of the second limiting groove and the second limiting ring, allows the mounting bracket to move with the winding roller 202, thereby facilitating the drive motor 206 to drive the rotation of the winding roller 202.

[0047] In this embodiment, the take-up roller 202 has a receiving cavity inside, and a pivot rod 203 has an extension hole 209. The extension hole 209 extends along the axial direction of the pivot rod 203 and is coaxially arranged with the pivot rod 203. The extension hole 209 connects the receiving cavity with the external space of the receiving cavity. The power supply wire passes through the extension hole 209 and enters the receiving cavity. The power supply components are located in the receiving cavity. The cable 103 is connected to the power supply components. The take-up roller 202 has a connection hole, and the cable 103 extends out of the receiving cavity through the connection hole.

[0048] The charging components are housed inside the take-up roller 202, and the cable 103 extends out of the take-up roller 202 through the connection hole. In this case, when the take-up roller 202 rotates, only the cable 103 outside the take-up roller 202 is wound onto the take-up roller 202. If the charging components were located on the inner wall of the housing 1, then when the cable 103 rotates, both sides of the fixing point between the take-up roller 202 and the cable 103 would need to be wound onto the take-up roller 202. This invention significantly reduces the complexity of the take-up mechanism 2 and lowers the difficulty of maintenance and repair.

[0049] Furthermore, by providing the extension hole 209, the power supply wire is placed inside the extension hole 209, so that the wire will not get tangled on the take-up roller 202 when the take-up roller 202 rotates, further improving the simplicity of the take-up mechanism 2.

[0050] Combination Figure 4 , Figure 5 and Figure 6As shown, the locking assembly includes a socket 501, a rod 502, a first locking block 503, a second locking block 504, and a first spring 505. The socket 501 is located on the housing 1, and the rod 502 is located on the cover 3. The rod 502 is used to be inserted into the socket 501. The side wall of the socket 501 is provided with a slot 506. The first locking block 503 is slidably disposed on the rod 502. The first locking block is used to extend out of the rod 502 due to sliding, and the first locking block is used to be stored in the rod 502 due to sliding.

[0051] The insertion rod 502 is provided with a locking groove 507. The second locking block 504 is slidably disposed in the insertion hole 501. A first spring 505 is provided between the second locking block 504 and the bottom surface of the insertion hole 501. When the insertion rod 502 is inserted into the insertion hole 501, the second locking block 504 is inserted into the locking groove 507. The second locking block 504 pushes the first locking block 503 to extend into the slot 506.

[0052] At this time, due to the locking of the first locking block 503 in the slot 506, the insertion rod 502 is not used to pull out to the outside of the insertion hole 501, thereby fixing the box cover 3 to the housing 1.

[0053] As a preferred technical solution, a lap joint 508 is provided on one side of the locking groove 507. A second spring 509 is provided between the lap joint 508 and the first locking block 503. When the second spring 509 is in its natural state, the first locking block 503 is housed in the insert rod 502. The first locking block 503 is provided with an inclined surface 510. The inclined surface 510 is arranged at an angle from the end near the first spring 505 to the end away from the first spring 505, from the axis away from the locking groove 507 to the axis near the locking groove 507. When the first locking block 503 is housed in the insert rod 502, the end of the inclined surface 510 away from the axis of the locking groove 507 is flush with the side wall of the second locking block 504. When the insert rod 502 is inserted into the insertion hole 501 and the first spring 505 is in its natural state, the second locking block 504 is inserted into the locking groove 507.

[0054] The second spring 509 facilitates the unlocking of the first locking block 503. When the second locking block 504 unlocks and pushes the first locking block 503, the first locking block 503 retracts into the insertion rod 502, allowing the insertion rod 502 to be pulled out to the outside of the insertion hole 501, thus unlocking the device.

[0055] The inclined surface 510 allows the second locking block 504 to push the first locking block 503 outward when the insertion rod 502 is inserted into the insertion hole 501, until the first locking block is locked in the slot 506, thereby facilitating the locking of the locking mechanism 5.

[0056] The insertion rod 502 is provided with an unlocking hole, which includes a large-diameter section 511 and a small-diameter section 512. The axis of the small-diameter section 512 is not on the same straight line as the axis of the large-diameter section 511. The unlocking hole is connected to the locking groove 507. The unlocking component includes a large-diameter rod 513 and a small-diameter rod 514. The diameter of the large-diameter rod 513 is the same as that of the large-diameter section 511, and the diameter of the small-diameter rod 514 is the same as that of the small-diameter section 512. The large-diameter section 511 is provided with a positioning groove, and the large-diameter rod 513 is provided with a positioning block 515. When the large-diameter rod 513 is inserted into the large-diameter section 511 and the positioning block 515 is inserted into the positioning groove, the small-diameter rod 514 is inserted into the small-diameter section 512. The length of the small-diameter rod 514 is greater than the length of the small-diameter section 512.

[0057] When the unlocking component 4 is inserted into the unlocking hole, the small diameter rod 514 will push the second locking block 504 to move outward of the locking groove 507 until the second locking block 504 releases the push of the first locking block 503. At this time, the first locking block 503 retracts, thus unlocking.

[0058] like Figure 7 and Figure 8 As shown, the charging gun 102 is provided with a protective block 104. The top of the protective block 104 is located on one side of the charging end of the charging gun 102. The protective block 104 is provided with a sealing groove 105. A sealing frame 106 is provided in the sealing groove 105 and can be flipped. The sealing frame 106 is L-shaped and a cover plate 107 is provided on the sealing frame 106. A torsion spring is provided between the sealing frame 106 and the side wall of the sealing groove 105. When the torsion spring is in its natural state, the cover plate 107 covers the charging end of the charging gun 102. The cover plate 107 is used to release the cover on the charging end due to the flipping of the sealing frame 106.

[0059] The cover 107 is designed to facilitate the sealing of the charging end of the charging gun 102, preventing damage to the charging gun 102 caused by rain, dust, etc.

[0060] Finally, the testing mechanism includes a button on the cover plate 107, a second button 109 on one end of the charging gun 102, and a control device 110 in the mounting cavity 101. The first button, the second button 109, and the drive motor 206 are all connected to the control device 110. After the charging gun 102 is pulled out of the charging vehicle, the cover plate 107 seals the charging end. The cover plate 107 presses the first button, and the drive motor drives the winding roller 202 to wind up. When the charging gun 102 comes into contact with the housing 1, the second button 109 is pressed, and the drive motor 206 stops working.

[0061] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
