For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] like Figures 1 to 5 As shown, the new energy charging pile of the present invention includes: an outer shell 1, which is equipped with a charging module 21 and a charging head 23 electrically connected to the charging module 21 through a cable 22; a driving shaft 3, which is rotatably arranged in the outer shell 1, and a winding sleeve 4 is provided on the outside of the driving shaft 3, and the winding sleeve 4 has a first end 41 and a second end 42 opposite to each other; a coil spring 5, which has an inner end and an outer end, the inner end is connected to the driving shaft 3, and the outer end is connected to the inner wall of the winding sleeve 4; a locking assembly, including a first locking member 61 arranged at the first end 41 of the winding sleeve 4 and rotating synchronously with the winding sleeve 4, and a second locking member 62 arranged on the driving shaft 3 and the inner wall of the outer shell 1, the second locking member 62 can move along the axial direction of the driving shaft 3 to lock or unlock the first locking member 61, when the first locking member 61 is locked, the winding sleeve 4 is restricted to not rotate, when the first locking member 61 is unlocked, the winding sleeve 4 is configured to be able to rotate relative to the driving shaft 3 to wind or release the cable 22.

[0020] See also Figure 2The charging module 21 can charge the power battery of the electric vehicle with direct current through the cable 22 and the charging head 23; the charging module 21 is configured on the outer shell 1. Specifically, the charging module 21 can be configured outside the outer shell 1, and the charging module 21 and the charging head 23 can be located on the same side surface of the outer shell 1.

[0021] See also Figure 2 , Figure 3 , Figure 5 The driving shaft 3 is horizontally rotated and installed in the outer shell 1. The driving shaft 3 is driven to rotate by a servo motor installed in the outer shell 1. A winding sleeve 4 is provided on the driving shaft 3. The winding sleeve 4 is coaxial with the driving shaft 3. The winding sleeve 4 and the driving shaft 3 are connected through a coil spring 5, wherein the inner end of the coil spring 5 is fixedly connected to the driving shaft 3, and the outer end of the coil spring 5 is fixedly connected to the inner wall of the winding sleeve 4.

[0022] See also Figures 3 to 5 The locking assembly comprises a first locking member 61 and a second locking member 62. The first locking member 61 is arranged at the first end 41 of the winding sleeve 4, and the second locking member 62 is arranged on the driving shaft 3 and the outer shell 1. The first locking member 61 is arranged to rotate synchronously with the winding sleeve 4, and the second locking member 62 is arranged to be able to move along the axial direction of the driving shaft 3 to approach or move away from the first locking member 61. The second locking member 62 does not rotate synchronously with the driving shaft 3. When the second locking member 62 approaches the driving shaft 3 at a predetermined distance, the first locking member 61 is locked. When the first locking member 61 is unlocked, the first locking member 61 can be limited by the second locking member 62, thereby limiting the rotation of the first locking member 61 and limiting the rotation of the winding sleeve 4 following the driving shaft 3 through the coil spring 5. When the second locking member 62 moves away from the first locking member 61 along the axial direction of the driving shaft 3, the first locking member 61 is unlocked. At this time, the first locking member 61 can rotate along the driving shaft 3 through the coil spring 5 or rotate relative to the driving shaft 3 with the help of the elastic potential energy stored in the coil spring 5.

[0023] Specifically, when it is necessary to store the cable 22 of the charging head 23, the servo motor is first used to control the rotation of the driving shaft 3, and the driving shaft 3 drives the coil spring 5 to rotate so that the coil spring 5 stores elastic potential energy. When the elastic potential energy of the coil spring 5 is stored to a certain threshold, the winding sleeve 4 rotates synchronously with the driving shaft 3 and the coil spring 5 to wind the cable 22 wound through the winding sleeve 4. When the cable 22 is wound, the rotating shaft end of the servo motor stops and the driving shaft 3 does not rotate. At this time, in order to avoid the winding sleeve 4 being unrestricted and causing the elastic potential energy stored in the coil spring 5 to be released and drive the winding sleeve 4 to reverse, it is necessary to control the second locking member 62 to move along the axial direction of the driving shaft 3, so that the second locking member 62 abuts against the first locking member 61, so that the first locking member 61 is locked by the second locking member 62, so as to realize the storage of the elastic potential energy of the coil spring 5 and realize the storage of the cable 22. It has the characteristics of simple structure and convenient operation, and at the same time reduces the possibility of damage caused by the cable 22 being exposed to the outside of the outer shell 1, and has practicality.

[0024] When the electric car needs to be charged in order to pull out the cable 22, the second locking member 62 is controlled to move away from the first locking member 61 along the axial direction of the driving shaft 3, so that the first locking member 61 and the winding sleeve 4 are unlocked. At this time, the elastic potential energy of the coil spring 5 is released, and the coil spring 5 drives the winding sleeve 4 to reverse, so that the cable 22 wound on the winding sleeve 4 can be sent out, so that the user can save more effort when pulling out the cable 22, thereby improving the use effect of the present application.

[0025] In one or more embodiments, the cable 22 wound on the surface of the winding sleeve 4 and located relatively in the middle of the winding sleeve 4 is fixed on the winding sleeve 4 .

[0026] It should be noted that the cable 22 wound near the first end 41 and the second end 42 of the winding sleeve 4 is in a relaxed state when not wound, and the cable 22 wound in the middle position of the winding sleeve 4 is fixed on the winding sleeve 4. The fixing method can be a method of fixing the cable 22 by a clamp, or a method of fixing with a rope, or other possible fixing methods.

[0027] In this way, it can be ensured that when the winding sleeve 4 rotates clockwise or counterclockwise, the cable 22 can move synchronously with the winding sleeve 4 to be wound or released on the winding sleeve 4, avoiding the situation where the winding sleeve 4 rotates and the cable 22 cannot be wound.

[0028] In one or more embodiments, a plurality of first magnets are disposed in the winding sleeve 4 along its axial direction, and a plurality of second magnets magnetically attracted to the first magnets are disposed in the cable 22 .

[0029] The accompanying drawings do not show the first magnet and the second magnet; when the winding sleeve 4 winds up and stores the cable 22, the second magnet disposed in the cable 22 is magnetically attracted to the first magnet disposed on the winding sleeve 4, so that the cable 22 can maximize the contact with the winding sleeve 4, thereby increasing the friction between the two and reducing the possibility of the cable 22 not being wound by the winding sleeve 4.

[0030] In other possible embodiments, a plurality of stop bars are disposed on the surface of the winding sleeve 4. When the winding sleeve 4 winds the cable 22, the stop bars rotate synchronously with the winding sleeve 4, and the stop bars can limit the cable 22, so that the cable 22 can be pressed into the winding sleeve 4 in a predetermined direction, further reducing the possibility that the cable 22 is not wound by the winding sleeve 4.

[0031] In one or more embodiments, the first locking member 61 is a first planar ratchet 611 that is arranged at the first end 41 of the winding sleeve 4 and rotates synchronously with the winding sleeve 4; the second locking member 62 is a second planar ratchet 621 and a clutch 622 that synchronously approach or move away from the first planar ratchet 611 along the axial direction of the driving shaft 3, the second planar ratchet 621 can engage with the first planar ratchet 611, and the clutch 622 has a supporting portion, and the clutch 622 uses the supporting portion to press against the second planar ratchet 621 to limit the rotation of the second planar ratchet 621, or the supporting portion moves away from the second planar ratchet 621 to release the restriction on the second planar ratchet 621.

[0032] See also Figures 3 to 5 The second planar ratchet 621 and the clutch 622 are configured to move synchronously to approach or move away from the first planar ratchet 611. The abutting portion of the clutch 622 is at a certain distance from the second planar ratchet 621 on the side away from the first planar ratchet 611. The abutting portion can be driven to approach and abut against the second planar ratchet 621, or driven away without contacting the second planar ratchet 621. The second planar ratchet 621 is configured to rotate along the central axis of the driving shaft 3, and the clutch 622 is configured not to rotate around the central axis of the driving shaft 3. The first planar ratchet 611 and the second planar ratchet 621 are configured to be meshed and connected.

[0033] See also Figures 3 to 5 When locking the winding sleeve 4, the second planar ratchet 621 and the clutch 622 are controlled to synchronously approach the first planar ratchet 611. When the second planar ratchet 621 is engaged with the first planar ratchet 611, the abutting portion of the clutch 622 is controlled to press against the second planar ratchet 621. At this time, the first planar ratchet 611 and the second planar ratchet 621 do not rotate, thereby achieving the locking of the winding sleeve 4. It has the characteristics of simple structure and convenient operation.

[0034] See also Figures 3 to 5 When the winding sleeve 4 is unlocked, the abutting part of the clutch 622 can be controlled to be away from the second planar ratchet 621. At this time, the second planar ratchet 621 is no longer restricted. Under the action of the elastic potential energy of the coil spring 5, the second planar ratchet 621 can rotate synchronously with the first planar ratchet 611. When the elastic potential energy of the coil spring 5 is released, the first planar ratchet 611 and the second planar ratchet 621 do not rotate. At this time, the second planar ratchet 621 and the clutch 622 can be controlled to be away from the first planar ratchet 611. In this way, the winding sleeve 4 can be automatically unlocked and locked, with a high degree of mechanization and low production cost.

[0035] In one or more embodiments, the second planar ratchet 621 is provided with a friction force enlarging portion on a surface of one side close to the abutting portion of the clutch 622. The friction force enlarging portion may be a frosted layer on the surface of the second planar ratchet 621, and is not specifically limited.

[0036] In one or more embodiments, the second planar ratchet 621 and the clutch 622 are arranged on a carrier plate, the inner wall of the outer shell 1 is provided with a driving device 7, and the carrier plate is driven by the driving device 7 along the axial direction of the driving shaft 3 to approach or move away from the first end 41 of the winding sleeve 4.

[0037] See also Figure 3 , the driving device 7 can be a driving cylinder, or a screw module, or other possible driving sources. When the driving device 7 is a driving cylinder, the extended shaft end of the driving cylinder is provided with a bearing plate, the second planar ratchet 621 and the clutch 622 are arranged on the bearing plate, and the second planar ratchet 621 can rotate relative to the bearing plate. When locking or unlocking the winding sleeve 4, it is only necessary to drive the cylinder to control the bearing to move closer to or away from the winding sleeve 4 so that the second planar ratchet 621 abuts against the first planar ratchet 611 or moves away from the first planar ratchet 611; by driving the cylinder to control the movement of the second planar ratchet 621, the displacement of the second planar ratchet 621 can be accurately controlled to avoid the problem that the second planar ratchet 621 moves excessively and causes the connection between the winding sleeve 4 and the coil spring 5 to break. At the same time, it has the characteristics of simple structure and low production cost, and is practical.

[0038] In one or more embodiments, a bearing is disposed on the surface of the winding sleeve 4 at the second end 42, and the cable 22 is wound around the bearing. Figure 3 Through this configuration, the wear of the cable 22 can be reduced and the service life of the cable 22 can be extended.

[0039] In other possible embodiments, the portion of the cable 22 near the charging module 21 is fixed to the inner wall of the outer shell 1. In this way, the problem of the cable 22 being overwound by the winding sleeve 4 and causing the connection between the cable 22 and the charging module 21 to be broken can be avoided.

[0040] In one or more embodiments, a wire management tube 8 is disposed on the outer surface of the outer shell 1, and the cable 22 connected to the charging head 23 passes through the wire management tube 8; the wire management tube 8 is trumpet-shaped at one end facing the top of the outer shell 1; and a ball is rotatably installed in the wire management tube 8.

[0041] See also Figure 2By configuring the charging head 23 on the wire management tube 8, it is convenient for users to take and place the charging head 23, and at the same time, the aesthetics of the charging pile is increased; by configuring the top of the wire management tube 8 into a trumpet shape, the charging head 23 can be further fixed, the wear at the contact point between the cable 22 and the wire management tube 8 can be reduced, and the service life of the cable 22 can be extended; by configuring balls in the cable 22, the contact friction between the cable 22 and the wire management tube 8 can be further reduced, making it convenient for users to take and place the charging head 23.

[0042] The above implementation modes are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
