DETAILED DESCRIPTION

[0036] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0037] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] See also Figure 1 This embodiment provides a remote-controlled mobile energy charging vehicle, including a vehicle body 10, a drive assembly 20, a winding roller 30, a wire 40, a power connection assembly 50, a battery 60, and an elastic return member 80. The winding roller 30 is movably disposed inside the vehicle body 10. One end of the wire 40 extends into the vehicle body 10 and is wound around the outside of the winding roller 30, and the other end extends outside the vehicle body 10 and is connected to a charging head (not shown). The drive assembly 20, the power connection assembly 50, and the battery 60 are all installed inside the vehicle body 10. The power connection assembly 50 is used to achieve electrical conduction between the battery 60 and the wire 40. The drive assembly 20 is used to drive the winding roller 30 to move, thereby driving the wire 40 to unwind from the outside of the winding roller 30. The elastic return member 80 is connected to the winding roller 30 at one end and to the inner wall of the vehicle body 10 at the other end. After charging is completed, the elastic return member 80 is used to cause the winding roller 30 to move in the opposite direction to rewind the wire 40.

[0039] When the vehicle needs to be charged, the charging head can be pulled, and the driving component 20 drives the winding roller 30 to move, so as to unwind the wire 40 from the outside of the winding roller 30, so that when the charging head is pulled, the wire 40 can be extended to the outside of the vehicle body 10, and the battery 60 and the wire 40 are electrically connected through the power connection component 50, and the vehicle is charged and replenished by utilizing the cooperation between the charging head and the vehicle charging socket; when the vehicle is charged, the charging head can be pulled out, and the elastic reset part 80 drives the winding roller 30 to move in the opposite direction, and then the wire 40 is wound, so that the wire 40 is moved to the inside of the vehicle body 10, and the wire 40 is stored and protected.

[0040] See also Figure 1 In one embodiment, the driving assembly 20 includes a driving rod 201 and a threaded section 202 arranged on the outer wall of the driving rod 201. The end of the driving rod 201 is fixedly connected to the inner wall of the vehicle body 10. The winding roller 30 is sleeved on the outside of the driving rod 201 and threadedly engaged with the threaded section 202.

[0041] When the charging head is pulled, the wire 40 is subjected to force and drives the winding roller 30 to rotate outside the driving rod 201, thereby unwinding the wire 40. At the same time, through the threaded fit between the winding roller 30 and the threaded section 202, the winding roller 30 can move along the length direction of the driving rod 201 when rotating, and the winding roller 30 can convey the wire 40 wound on its outside when moving, avoiding a large directional deflection inside the vehicle body 10 when the wire 40 is unwound, thereby improving the convenience of removing the wire 40 from the vehicle body 10; the rotation of the winding roller 30 and the movement of the driving rod 201 During the movement in the length direction, the elastic reset member 80 can be driven to twist and compress. When the vehicle is charged and recharged, the charging head can be pulled out of the vehicle charging socket. At this time, the rotation and extension of the elastic reset member 80 can drive the winding roller 30 to rotate in the opposite direction and move in the opposite direction along the length direction of the driving rod 201. When the winding roller 30 rotates in the opposite direction, the wire 40 can be wound. When the winding roller 30 moves in the opposite direction, the wire 40 wound on the outside of the winding roller 30 can be evenly and orderly distributed along its length direction, thereby avoiding the wires 40 from stacking and squeezing each other, thereby achieving protection of the wires 40.

[0042] See also Figure 1 and Figure 2 In one embodiment, the power connection assembly 50 includes a conductive rod 501 and a conductive disk 503. The conductive disk 503 is fixedly arranged on the outside of the winding roller 30. One end of the conductive rod 501 slides with the inner wall of the vehicle body 10, and the other end extends to one side of the conductive disk 503. The conductive rod 501 is connected to the battery 60 via a wire, and the conductive disk 503 is connected to the wire 40 via a wire. A first elastic member 502 is also provided inside the vehicle body 10. The first elastic member 502 is used to provide elastic tension to the conductive rod 501.

[0043] When the charging head is pulled to drive the wire 40 to extend out of the vehicle body 10, the roller 30 rotates and moves along the length direction of the driving rod 201. When the roller 30 rotates and moves, it can drive the conductive disk 503 to rotate and move synchronously, so that the conductive disk 503 can fit on one side of the conductive rod 501 and push the conductive rod 501 to move along the inside of the vehicle body 10. At this time, the elastic tension provided by the first elastic member 502 to the conductive rod 501 makes the conductive rod 501 in close contact with the conductive disk 503. The battery 60 can charge and replenish the vehicle through the conductive rod 501, the conductive disk 503, the wire 40 and the charging head; when the vehicle is charged and replenished The elastic return member 80 drives the winding roller 30 to rotate in the opposite direction and move in the opposite direction along the length direction of the driving rod 201. When the winding roller 30 moves in the opposite direction, it can drive the conductive disk 503 to move in the opposite direction. The first elastic member 502 drives the conductive rod 501 to move in the opposite direction. When the winding roller 30 moves in the opposite direction to the initial position, the conductive disk 503 and the conductive rod 501 are in a separated state, that is, the battery 60 and the wire 40 are electrically disconnected. The purpose of this arrangement is that when the charging head does not need to charge the vehicle, the charging head and the battery 60 are electrically disconnected, so as to prevent the charging head from being electrically connected to the battery 60 for a long time and avoiding overheating and damage to the charging head.

[0044] See also Figure 1 In one embodiment, a guide rail 102 is fixedly provided on the inner wall of the vehicle body 10, and one end of the conductive rod 501 is slidably engaged with the guide rail 102 via a slider.

[0045] See also Figure 1 In one embodiment, a non-return assembly 70 is further provided inside the vehicle body 10, and the non-return assembly 70 is used to apply resistance to the wire 40 to overcome the rotational force applied by the elastic return member 80 to the winding roller 30, thereby preventing the wire 40 from being subjected to tension from inside the vehicle body 10 during the vehicle charging process, thereby preventing the charging head from loosening or even detaching inside the charging jack.

[0046] See also Figure 4 In one embodiment, the non-return assembly 70 includes a pressure plate 704, a third elastic member 705, a non-return plate 706 and a support plate 707, one end of the support plate 707 is fixedly connected to the inner wall of the vehicle body 10, the pressure plate 704 is arranged on one side of the support plate 707, the wire 40 passes between the support plate 707 and the pressure plate 704, the non-return plate 706 is hingedly arranged on the side of the pressure plate 704 facing the support plate 707, one end of the third elastic member 705 is connected to the pressure plate 704, and the other end is connected to the non-return plate 706, for providing elastic support for the non-return plate 706.

[0047] When the charging head is pulled to drive the wire 40 to extend outside the vehicle body 10, an elastic supporting force is applied to the check plate 706 through the third elastic member 705, so that one end of the check plate 706 presses the wire 40 against one side of the support plate 707, thereby limiting the movement of the wire 40 toward the inside of the vehicle body 10, preventing the charging head from being loosened or detached from the vehicle charging socket due to the pulling of the wire 40 when the vehicle is charging.

[0048] See also Figure 4 In one embodiment, a slide groove 103 is provided on the side wall of the vehicle body 10, and a support rod 703 is fixedly provided on the side of the pressure plate 704 away from the support plate 707. One end of the support rod 703 extends from the slide groove 103 to the outside of the vehicle body 10 and is fixedly provided with a paddle 701. A second elastic member 702 is also provided between the support rod 703 and the inner wall of the slide groove 103, and the second elastic member 702 is used to provide elastic support for the support rod 703.

[0049] When the vehicle is fully charged, the charging head can be pulled out, and then the paddle 701 can be toggled, thereby driving the support rod 703 to slide along the inside of the slide groove 103, and then driving the pressure plate 704 to move away from the support plate 707, so that the non-return plate 706 is away from the wire 40, thereby releasing the non-return effect on the wire 40. Under the rotation and extension of the elastic reset member 80, the winding roller 30 can wind the wire 40 to achieve the storage and protection of the wire 40. When the wire 40 is wound around the outside of the winding roller 30, the paddle 701 is released, and the second elastic member 702 drives the support rod 703 to slide in the opposite direction along the inside of the slide groove 103, and the pressure plate 704 moves toward the support plate 707, and the non-return plate 706 presses the wire 40 against one side of the support plate 707 again.

[0050] In one embodiment, the first elastic member 502 , the second elastic member 702 and the third elastic member 705 may be springs or metal springs, which are not limited here. The elastic return member 80 is a spring.

[0051] See also Figure 3 In one embodiment, a damping member 90 is further provided on the outer wall of the driving rod 201, and the damping member 90 is used to provide a damping effect on the movement of the winding roller 30 along the outside of the driving rod 201, thereby adjusting the reverse rotation speed of the winding roller 30 and the reverse movement speed along the outside of the driving rod 201, avoiding the reverse rotation speed of the winding roller 30 being too fast and the reverse movement speed being too fast, thereby ensuring the winding effect of the wire 40 outside the winding roller 30.

[0052] See also Figure 3In one embodiment, the damping member 90 includes a plurality of rubber blocks 901 arranged along the length direction of the outer wall of the driving rod 201. The rubber blocks 901 are triangular in structure, hollow inside, and air holes 902 are opened on the side walls of the rubber blocks 901.

[0053] When the charging head is pulled to drive the wire 40 to extend out of the vehicle body 10, the winding roller 30 rotates and moves along the outside of the driving rod 201. During this process, the winding roller 30 can act on the inclined position of the rubber block 901, thereby squeezing the rubber block 901 so that the air inside the rubber block 901 is quickly discharged from the air hole 902. The rubber block 901 is deformed by pressure and its volume is reduced until the rubber block 901 moves to the outside of the winding roller 30. At this time, the movement damping of the winding roller 30 is small, and the movement of the winding roller 30 is relatively smooth. When charging is completed, When the winding roller 30 rotates in the opposite direction and moves in the opposite direction along the outside of the driving rod 201, the end of the winding roller 30 can act on the vertical surface of the rubber block 901 and fit against the outside of the air hole 902 to seal the air hole 902. At this time, the air inside the rubber block 901 cannot be discharged quickly, the deformation speed of the rubber block 901 is slow, and the volume reduction is small, so that the movement damping of the winding roller 30 is large, and the movement speed of the winding roller 30 is slowed down, thereby realizing slow winding of the wire 40 and improving the winding effect of the wire 40.

[0054] See also Figure 1 In one embodiment, a plurality of casters 101 are installed on the side walls of the vehicle body 10 to facilitate the flexible movement of the energy charging vehicle.

[0055] In one embodiment, the vehicle body 10 has a remote control function, so that the vehicle body 10 can be remotely controlled and moved to the front of the vehicle that needs to be charged to realize the charging and energy replenishment of the vehicle. As for the sensors, signal transceivers, controllers and other components required to realize the remote control function, they are common knowledge in the field and will not be elaborated here.

[0056] In an embodiment of the present invention, when the vehicle needs to be charged, the charging head can be pulled, and the driving component 20 drives the winding roller 30 to move, so as to unwind the wire 40 from the outside of the winding roller 30, so that when the charging head is pulled, the wire 40 can be extended to the outside of the vehicle body 10, and the battery 60 and the wire 40 are electrically connected through the power connection component 50, and the vehicle is charged and replenished by utilizing the cooperation between the charging head and the vehicle charging socket; when the vehicle is charged, the charging head can be pulled out, and the elastic return member 80 drives the winding roller 30 to move in the opposite direction, thereby winding the wire 40, so that the wire 40 is moved to the inside of the vehicle body 10. Compared with the prior art, when charging and replenishing are not needed, the wire 40 can be reeled and protected, which on the one hand avoids long-term exposure of the wire 40 to the outside air, effectively prevents accidental damage and aging of the wire 40, improves safety and prolongs service life, and on the other hand, it can achieve orderliness during the storage process of the wire 40, and improves the convenience of subsequent use of the wire 40.

[0057] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of this patent.
