Description

Technical Field

[0001] This invention belongs to the field of charging pile cable storage technology, specifically relating to a charging cable storage device for new energy vehicle charging piles. Background Technology

[0002] When the battery of a new energy vehicle is about to run out, it will use a charging station to charge. There are many public charging stations outdoors. After parking the car in front of the charging station, unplug the charging station and pull the power cable to the designated location. Then plug the charging plug into the charging port of the new energy vehicle to charge the car.

[0003] Outdoors, especially in summer, the ground temperature is often higher than the air temperature. Charging pile cables are generally quite long, and when they are pulled out, part of them will fall to the ground, which will further increase the temperature of the cables. At the same time, when the cables are pulled out, they will rub against the ground. Therefore, the friction between the ground and the cables, combined with the increase in ground temperature, can easily increase the wear and tear on the cables, thus affecting their service life. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to provide a charging cable storage device for new energy vehicle charging piles, which can solve the problem that friction between the ground and the cable, coupled with the increase in ground surface temperature, easily increases the wear and loss of the cable, thereby affecting the service life of the cable.

[0005] To address the aforementioned issues, this invention provides a charging cable storage device for new energy vehicle charging piles, comprising: a storage box, wherein two top shafts are rotatably connected between two opposite sides of the top of the storage box, and guide wheels are rotatably connected to each of the two top shafts;

[0006] A support column is fixedly connected to the bottom center of the storage box. A cable winding mechanism is set at the bottom of the support column for winding and unwinding the charging pile cable.

[0007] A push-pull mechanism is also provided on the outside of the support column, which is used to push and pull the cable winding mechanism.

[0008] The storage box also has a ventilation mechanism on the top and side walls to control the operating temperature of the push-pull mechanism.

[0009] Furthermore, the cable winding mechanism includes a guiding part and a limiting part. The guiding part includes a guiding slider, which is slidably connected to the support column. The side of the guiding slider is provided with an installation groove. Sliding grooves are provided on the two opposite side walls of the installation groove. An installation plate is provided in the installation groove, and the two opposite sides of the installation plate are slidably connected to the two sliding grooves respectively.

[0010] Furthermore, the guide section also includes an upper shaft, which is fixedly connected to the top of the mounting plate on the side away from the support column. A guide disk is rotatably connected to the outer periphery of the upper shaft, and the outer periphery of the guide disk is set in an inward arc shape. A limiting shaft is rotatably connected to the bottom of the mounting plate on the side away from the support column.

[0011] Furthermore, the limiting part includes two inner grooves, and a guide shaft is provided between the two inner grooves. The two ends of the guide shaft extend into the two inner grooves respectively and are rotatably connected to the inner grooves. Hollow plate one and hollow plate two are fixedly connected to the outer side wall of the shaft respectively. A connecting plate is slidably connected in hollow plate one, and the side of the connecting plate extends to the slide plate and is hinged to the mounting plate. A piston plate is slidably connected in hollow plate two. A number of limiting grooves are opened on the support column, and the side of the piston plate extends into the corresponding limiting groove.

[0012] Furthermore, one end of the guide shaft is provided with a cavity, the side of the hollow plate II extends into the cavity and communicates with the cavity, and the side of the guide slider is fixedly connected with an electric telescopic rod, the telescopic end of the electric telescopic rod extends into the cavity and is slidably connected to the cavity.

[0013] Furthermore, the push-pull mechanism includes a thermal spring, which is sleeved on the support column and its top end is fixedly connected to the top side of the storage box, and its bottom end is fixedly connected to the top side of the guide slider. A control part is also provided on the top side of the storage box to control the extension and retraction of the thermal spring.

[0014] Furthermore, the control unit includes a cable outlet, a heat-conducting shaft is rotatably connected to the top of the inner wall of the cable outlet, a heat-conducting wire is rotatably connected to the end of the heat-conducting shaft, and the end of the heat-conducting wire extends into the storage box and is fixedly connected to the outer wall of the thermal spring.

[0015] Furthermore, the ventilation mechanism includes two sealing plates, which are fixedly connected to the top side of the guide slider, and the top of the storage box has ventilation openings corresponding to the positions of the two sealing plates.

[0016] In summary, the present invention has at least one of the following beneficial technical effects:

[0017] This new energy vehicle charging pile charging cable storage device allows the cable to be pulled out directly for use, preventing it from contacting the ground and thus avoiding friction and heat conduction, which would increase cable loss. The push-pull mechanism also assists in pulling out and storing the cable, reducing the pulling force on the cable, thereby reducing cable loss and extending its service life.

[0018] This new energy vehicle charging pile charging cable storage device guides the slider to move upward. After the cable is pulled to the appropriate position, the sealing plate will be inserted into the vent, keeping the storage box in a closed state and making it easier for the internal temperature to rise. After the cable is retracted, the vent opens, which can quickly cool the inside of the storage box, allowing the thermal spring to quickly return to its original temperature, facilitating the subsequent cable retraction and extension.

[0019] This is a charging cable storage device for new energy vehicle charging piles. When the cable is pulled, the contraction of the thermal spring will pull the guide slider, assisting the guide slider to rise and reducing the force required to pull the cable. After charging, the thermal spring is in a heated state. After heating, the thermal spring will extend. Therefore, after the restriction on the guide slider is released, it will assist the gravity of the guide slider to push it downward, so that the cable can be retracted to its original position more quickly.

[0030] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," 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 this 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 limitations on this invention.

[0031] Furthermore, 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, unless otherwise explicitly specified.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0034] See also Figures 1-8As shown, according to Embodiment 1 of the present invention, a charging cable storage device for a new energy vehicle charging pile is provided, comprising: a storage box 1, wherein two top shafts 2 are rotatably connected between two opposite sides of the top of the storage box 1, and guide wheels 3 are rotatably connected to both top shafts 2;

[0035] A support column 4 is fixedly connected to the bottom center of the storage box 1. A cable winding mechanism 5 is provided at the bottom of the support column 4 for winding and unwinding the charging pile cable.

[0036] A push-pull mechanism 6 is also provided on the outside of the support column 4. The push-pull mechanism 6 is used to push and pull the cable winding mechanism 5.

[0037] The storage box 1 is also equipped with a ventilation mechanism 7 on the inner top side wall to control the working temperature of the push-pull mechanism 6.

[0038] In this embodiment, combined with Figure 8 See again Figure 2 The cable enters from the bottom left side of the storage box 1, then goes up around the first guide wheel 3, then down to the cable winding mechanism 5, then extends up from the cable winding mechanism 5 to the right guide wheel 3, then goes to the outside of the storage box 1 and connects to the charging plug for car charging.

[0039] Pulling the plug directly will activate the cable retraction mechanism 5, releasing the cable from its restraint. The cable can then be pulled out. After the charging plug is pulled to the car and connected to the plug in the car, the cable retraction mechanism 5 will restrain the cable to prevent it from retracting and pulling the cable back, which would affect the charging operation of the charging plug.

[0040] When the cable is pulled, a push-pull mechanism 6 is used to assist the cable retraction mechanism 5 in reducing the pulling force on the cable. This allows the cable to be pulled out with the help of the push-pull mechanism 6 when the charging head is pulled, reducing the pulling force on the cable and minimizing cable loss due to the pulling force. Therefore, this can protect the cable to the greatest extent, reducing the loss caused by ground friction and pulling force when the cable is pulled during use. It can also prevent the cable from contacting the ground, which would increase the temperature of the cable due to the high temperature of the ground and thus reduce its service life.

[0041] In a further preferred embodiment of the invention, such as Figure 3 and Figure 4As shown, the cable winding and unwinding mechanism 5 includes a guiding part and a limiting part. The guiding part includes a guiding slider 8, which is slidably connected to the support column 4. The side of the guiding slider 8 is provided with an installation groove 9. The two opposite side walls of the installation groove 9 are provided with sliding grooves 10. An installation plate 11 is provided in the installation groove 9. The two opposite sides of the installation plate 11 are slidably connected to the two sliding grooves 10 respectively.

[0042] The guide section also includes an upper shaft 12, which is fixedly connected to the top of the mounting plate 11 on the side away from the support column 4. A guide disk 13 is rotatably connected to the outer periphery of the upper shaft 12. The outer periphery of the guide disk 13 is set in an inward arc shape. A limiting shaft 14 is rotatably connected to the bottom of the mounting plate 11 on the side away from the support column 4.

[0043] In this embodiment, combined with Figure 8 For further reference Figures 3-4 When laying cables, they will be routed around the bottom of the guide plate 13, and a limiting shaft 14 will also be used to limit them to prevent the cables from coming off the outer periphery of the guide plate 13.

[0044] When the charging head of the cable is pulled, the cable itself is stretched, which pushes the guide plate 13 upward, causing the guide plate 13 to move upward. When the guide plate 13 moves upward, it will push the mounting plate 11 upward through the upper shaft 12, causing the mounting plate 11 to drive the entire guide slider 8 upward, allowing the guide slider 8 to slide upward on the support column 4, so that the guide slider 8 can move upward as a whole. Then the cable will be pulled out by the charging head. After the distance pulled out is sufficient for use, the continuous outward pulling of the cable will be released after the charging head is connected to the charging port on the car. Then the guide slider 8 is limited by the limiting part. At this time, the cable will be supported by the limiting shaft 14, reducing the force of the cable being stretched after it falls due to its own weight.

[0045] In a further preferred embodiment of the invention, such as Figures 3-4 and Figure 8 As shown, the limiting part includes two inner grooves 15, and a guide shaft 16 is provided between the two inner grooves 15. The two ends of the guide shaft 16 extend into the two inner grooves 15 respectively and are rotatably connected to the inner grooves 15. Hollow plate 17 and hollow plate 28 are fixedly connected to the outer side wall of the shaft respectively. A connecting plate 19 is slidably connected in the hollow plate 17, and the side of the connecting plate 19 extends to the slide plate and is hinged to the mounting plate 11. A piston plate 20 is slidably connected in the hollow plate 28. A number of limiting grooves 21 are opened on the support column 4, and the side of the piston plate 20 extends into the corresponding limiting groove 21.

[0046] In this embodiment, combined with Figure 8 For further reference Figure 3 andFigure 4 In the limiting part, the mounting plate 11 is pressed down by the guide plate 13, so that the mounting plate 11 is located at the bottom of the slide groove 10. The hollow plate 17 and hollow plate 18 on the guide shaft 16 are hinged to the mounting plate 11. The connecting plate 19 is pressed down by the mounting plate 11 when it slides down, so that the piston plate 20 on the hollow plate 18 abuts against the corresponding limiting groove 21 on the support column 4. At this time, the limiting of the piston plate 20 is used to position the entire guide slider 8 on the support column 4. In order to improve the limiting of the guide slider 8 by the guide shaft 16, a torsion spring is fixedly connected in one of the inner grooves 15 and fixedly connected to the end of the guide shaft 16. Then, under the drive of the torsion spring torque, the guide shaft 16 will rotate upward on the hollow plate 18 in the initial state, so that the piston plate 20 is inserted into and abuts against the inner wall of the corresponding limiting groove 21.

[0047] When the guide plate 13 is pulled upward by the cable, it will push the connecting plate 19 upward through the mounting plate 11. The connecting plate 19 will drive the rotation of the guide shaft 16, so that the guide shaft 16 can drive the gap plate 2 to rotate the piston plate 20, causing the piston plate 20 to rotate downward and disengage from the limiting groove 21. At this time, the guide slider 8 is released from the limitation, so the guide slider 8 can be pulled upward when the cable is pulled out. When the cable stops being pulled, the force of the torsion spring and the downward pressure of the cable and the guide plate 13 will drive the rotation of the guide shaft 16, so that the side of the piston plate 20 will re-insert into the corresponding limiting groove 21, thereby limiting the guide slider 8. This achieves the effect of quickly pulling out the cable for charging and avoiding the cable from contacting the ground and increasing its wear.

[0048] In a further preferred embodiment of the invention, such as Figures 4-5 and Figure 8 As shown, one end of the guide shaft 16 has a cavity 22, the side of the hollow plate 18 extends into the cavity 22 and communicates with the cavity 22, and the side of the guide slider 8 is fixedly connected to an electric telescopic rod 23, the telescopic end of the electric telescopic rod 23 extends into the cavity 22 and is slidably connected to the cavity 22.

[0049] In this embodiment, combined with Figure 8 ,refer to Figure 4 and Figure 5After charging is complete, the electric telescopic rod 23 can be controlled to retract, causing the telescopic end of the electric telescopic rod 23 to retract within the cavity 22, thereby drawing out the air from the sliding hole and the hollow plate 18, creating a negative pressure inside. This causes the piston plate 20 to retract along the side of the hollow plate 18, performing piston movement. The hollow plate 18 and the piston plate 20 are sealed together. At this time, the piston plate 20 is disengaged from the limiting groove 21, and then it will descend using the gravity of the guide slider 8 and the guide plate 13, allowing the cable to be pulled back into the storage box 1, achieving the storage function. A controller can be installed on the charging plug to drive the telescopic operation of the electric telescopic rod 23.

[0050] In a further preferred embodiment of the invention, such as Figure 6 and Figure 7 As shown, the push-pull mechanism 6 includes a thermal spring 24, which is sleeved on the support column 4 and its top end is fixedly connected to the top side of the storage box 1, and its bottom end is fixedly connected to the top side of the guide slider 8. A control part 25 is also provided on the top side of the storage box 1 to control the extension and retraction of the thermal spring 24.

[0051] The control unit 25 includes a cable outlet 26. A heat-conducting shaft 27 is rotatably connected to the top of the inner side wall of the cable outlet 26. A heat-conducting wire 28 is rotatably connected to the end of the heat-conducting shaft 27. The end of the heat-conducting wire 28 extends into the storage box 1 and is fixedly connected to the outer side wall of the thermal spring 24.

[0052] In this embodiment, combined with Figure 8 For further reference Figure 6 and Figure 7 The outer periphery of the cable is in contact with the heat-conducting shaft 27. After the cable is pulled out, during charging, the charging voltage of the external charging station is higher than that of the household charging voltage, so the cable temperature will rise. After the cable temperature rises, the heat will be conducted by the heat-conducting shaft 27 and the heat-conducting wire 28. The heat-conducting shaft 27 can be made of copper or diamond, so that the heat can be conducted to the heat-conducting wire 28. The heat-conducting wire 28 can be made of copper or silver, so that the heat can be quickly conducted to the position of the thermal spring 24.

[0053] In the initial state, when the cable is not pulled out for charging, the thermal spring 24 is at room temperature and in a contracted state. When the cable is pulled, the contraction of the thermal spring 24 will pull the guide slider 8, assisting the guide slider 8 to rise and reducing the force required to pull the cable. After charging, the thermal spring 24 is in a heated state. After heating, the thermal spring 24 will extend. Therefore, after the constraint on the guide slider 8 is released, it will assist the gravity of the guide slider 8 to push it downward, so that the cable can retract to its original position more quickly.

[0054] In a further preferred embodiment of the invention, such as Figure 2As shown, the ventilation mechanism 7 includes two sealing plates 29, which are fixedly connected to the top side of the guide slider 8. The top of the storage box 1 has ventilation openings 30 corresponding to the positions of the two sealing plates 29.

[0055] In this embodiment, combined with Figure 8 ,refer to Figure 2 When the guide slider 8 moves upward, after the cable is pulled to the appropriate position, the sealing plate 29 will be inserted into the vent 30, keeping the storage box 1 in a closed state, making it easier for the internal temperature to rise. After the cable is retracted, the vent 30 opens, which can quickly cool the inside of the storage box 1, allowing the thermal spring 24 to quickly return to its original temperature, facilitating the subsequent cable retraction and extension.

[0056] Working principle: When laying cables, they will pass around the bottom of the guide plate 13, and there will also be a limiting shaft 14 to limit them to prevent the cables from leaving the outer periphery of the guide plate 13.

[0057] When the charging head of the cable is pulled, the cable itself is stretched, which pushes the guide plate 13 upward, causing the guide plate 13 to move upward. When the guide plate 13 moves upward, it will push the mounting plate 11 upward through the upper shaft 12, causing the mounting plate 11 to drive the entire guide slider 8 upward, allowing the guide slider 8 to slide upward on the support column 4, so that the guide slider 8 can move upward as a whole. Then the cable will be pulled out by the charging head. After the distance pulled out is sufficient for use, the continuous outward pulling of the cable will be released after the charging head is connected to the charging port on the car. Then the guide slider 8 is limited by the limiting part. At this time, the cable will be supported by the limiting shaft 14, reducing the cable's own pulling force after it falls due to its own weight.

[0058] The mounting plate 11 is pressed down by the guide plate 13, so that the mounting plate 11 is located at the bottom of the slide groove 10. The hollow plates 17 and 18 on the guide shaft 16 are positioned, and the connecting plate 19 is hinged to the mounting plate 11. When the mounting plate 11 slides down, the connecting plate 19 is pressed down, so that the piston plate 20 on the hollow plate 18 abuts against the corresponding limiting groove 21 on the support column 4. At this time, the limiting of the piston plate 20 is used to position the entire guide slider 8 on the support column 4. In order to improve the limiting of the guide slider 8 by the guide shaft 16, a torsion spring is fixedly connected in one of the inner grooves 15 and fixedly connected to the end of the guide shaft 16. Then, driven by the torsion of the torsion spring, the guide shaft 16 will rotate upward on the hollow plate 18 in the initial state, so that the piston plate 20 inserts into and abuts against the inner wall of the corresponding limiting groove 21.

[0059] When the guide plate 13 is pulled upward by the cable, it will push the connecting plate 19 upward through the mounting plate 11. The connecting plate 19 will drive the rotation of the guide shaft 16, which in turn drives the gap plate 2 to rotate the piston plate 20, causing the piston plate 20 to rotate downward and disengage from the limiting groove 21. At this time, the guide slider 8 is released from its constraint, so it can be pulled upward when the cable is pulled outward. When the cable stops pulling, the force of the torsion spring and the downward pressure of the cable and guide plate 13 will drive the rotation of the guide shaft 16, causing the side of the piston plate 20 to re-insert into the corresponding limiting groove. Within 21, the guide slider 8 is confined; after charging is complete, the electric telescopic rod 23 can be controlled to retract, causing the telescopic end of the electric telescopic rod 23 to retract within the cavity 22, thereby drawing out the air from the sliding hole and the hollow plate 18, creating a negative pressure inside, which in turn causes the piston plate 20 to retract on the side of the hollow plate 18, performing piston movement. The hollow plate 18 and the piston plate 20 are sealed together. At this time, the piston plate 20 is disengaged from the confining groove 21, and then the guide slider 8 and the guide plate 13 will descend by gravity, allowing the cable to be pulled back into the storage box 1, achieving the purpose of storage.

[0060] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[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. The above are merely preferred embodiments of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
