Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a wire storage device for a charging pile gun wire. Background Art

[0002] At present, with the advancement of technology and the enhancement of environmental awareness in modern society, the number of new energy vehicles is showing a rapid growth trend. In order to meet the power supply needs of new energy vehicles, charging piles, as a device for charging new energy vehicles, are also increasing in number. The charging gun, as the output port of the charging pile, is connected to the car charging port to achieve charging. The charging gun and the charging pile are connected by a gun line, which allows the charging gun to be stretched to adapt to different lengths of distance when connected to the car charging port.

[0003] The gun wire of a traditional charging gun is generally exposed directly on the outside of the charging pile, which can easily cause the gun wire to age. Since some gun wires are heavy, users may pile them directly on one side of the charging pile after charging is completed, or coil them and hang them randomly, which may cause safety hazards.

[0004] In order to solve these problems, a wire-retracting mechanism is designed in the prior art. Common wire-retracting mechanisms include an automatic retracting wire-retracting mechanism, which includes a box body with a spring or other elastic member inside. The gun line is pulled out by human dragging when in use, and is automatically retracted by the tension of the spring after charging is completed. Although this mechanism is convenient for the recovery of the gun line, it may be laborious to pull out some heavier gun lines, and the elastic force of the spring may decrease after long-term use, resulting in poor automatic recovery effect. Another common folding arm wire-retracting mechanism supports the folding arm through a column, and the folding arm is provided with a hanging ring for passing the charging gun line. The folding arms are connected by a hinge shaft and can be folded and extended section by section. This mechanism has a simple structure and is easy to maintain. The height of the connection point between the folding arm and the column can be designed according to actual needs to ensure that the gun line does not drag on the ground, but it still needs to be manually operated by the folding arm to store and unfold the gun line, which is laborious and the gun line is still exposed.

[0005] The invention patent document application with application publication number CN118722283A and application publication date 2024 / 10 / 01 discloses a wall-mounted charging pile with a wire-taking mechanism, the device comprising a charging pile body, the charging pile body having a wire-taking bin, the inner top wall of the wire-taking bin is provided with a plurality of fixed groove wheels; a lifting mechanism is provided in the wire-taking bin, the lifting mechanism comprises a plurality of lifting blocks, and the plurality of lifting blocks and the plurality of fixed groove wheels are arranged at intervals and staggered with each other; the lifting block is connected with a movable groove wheel, the fixed groove wheel and the movable groove wheel are used for the cable to bypass in sequence, and one end of the cable passes through the side wall of the wire-taking bin, which is used to drive the lifting block to lift and lower through the lifting mechanism, and realize the release and take-up of the cable by rising and falling the movable groove wheel.

[0006] The cable-winding mechanism passes the cable around the fixed groove wheel and the movable groove wheel in turn, and uses the rise of the movable groove wheel to release the cable and the descent of the movable groove wheel to wind up the cable, which solves the problem of manual cable storage and poor convenience in use. However, during use, most vehicles are parked close to the charging pile, so the cable is mainly wound up and released in the use of the lifting mechanism close to the charging gun, and the number of times the gun line at the rear is wound up and released is less, which will cause the gun line at the front to be prone to fatigue and damage. Summary of the invention

[0007] The object of the present invention is to provide a wire storage device for a charging pile gun wire, so as to solve the problem that the gun wire in the existing charging pile is prone to fatigue and damage.

[0009] Furthermore, the transmission mechanism includes synchronous gears which are arranged at the same end of the screw rods in a one-to-one correspondence, and the synchronous gears of two adjacent screw rods are meshed with each other.

[0010] Furthermore, the driving device is a motor, and the motor is transmission-connected to the corresponding screw through a reducer.

DETAILED DESCRIPTION

[0020] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0021] The charging pile gun line storage device of the present invention can solve the problem that the gun line in the existing charging pile is prone to fatigue and damage. The charging pile gun line storage device of the present invention uses the threaded cooperation between the lead screw and the slider for transmission, and the lead screws are synchronously driven and the rotation directions of two adjacent lead screws are opposite, so that the cable can be folded into an "S" shape on the wire storage rack to achieve the purpose of winding the wire, and the device of the present invention has a simple structure and is easy to operate.

[0022] As a basic solution, Figure 1-5 As shown, a wire storage device for a charging pile gun wire of the present invention comprises a wire storage rack 1, which is used to store the wire 3 and complete the winding and unwinding of the wire 3 through a mechanism installed on the wire storage rack 1, so that the wire 3 can be neatly stored to avoid being entangled with other wires 3. The wire storage rack 1 comprises two support rods 2 arranged at intervals, and a plurality of guide rods 4 arranged in sequence along the support rods 2 are fixedly connected between the two support rods 2. The support rods 2 are mainly used to fix the guide rods 4, which serve as the basic support of the device to improve the stability of the device. The guide rods 4 are provided with sliders 5 for driving the cables 3 to reciprocate, and each of the sliders 5 is respectively provided with an annular member 6 for the cable 3 to pass through. The annular member 6 can drive the cable 3 to move, and can also arrange the cables 3 neatly and orderly when in use, thereby improving the aesthetics of the device, and it has strong applicability and can be used for cables 3 of different lengths and diameters. A screw rod 7 corresponding to the slider 5 is installed between the two support rods 2, and the slider 5 can be driven by the corresponding screw rod 7. The corresponding guide rod 4 along the lower edge reciprocates, and the slider 5 reciprocates on the screw rod 7 to realize the process of winding and releasing the cable 3. The screw rod 7 has the advantages of high bearing capacity, simple structure and easy operation, and the sliders 5 corresponding to two adjacent screw rods 7 move in opposite directions, so that the cable 3 can move in a "Z" shape between two adjacent sliders 5, which can significantly reduce the linear space required for the cable 3 and make full use of the limited space. The screw rods 7 are synchronously connected by a transmission mechanism. The synchronous transmission can ensure that the load on each screw rod 7 is relatively uniform, and can avoid the problem that the cable 3 frequently moves back and forth on the sliders 5 of several of the screw rods 7 and causes fatigue and requires frequent maintenance. In addition, the synchronous rotation of the screw rods 7 can improve the transmission efficiency. One of the screw rods 7 is connected to a drive device, which is powered by the drive device. The drive device can convert other energy into mechanical energy to drive the device to move, and has a high conversion efficiency to reduce energy loss.

[0023] As a preferred embodiment, Figure 3-4As shown, the transmission mechanism includes synchronous gears 8 which are arranged one by one at the same end of the screw rod 7. The synchronous gears 8 of two adjacent screw rods 7 mesh with each other. The synchronous gears 8 have high transmission efficiency and good load-bearing capacity and can withstand large torque and load. The mutual meshing between the synchronous gears 8 drives the two adjacent corresponding screw rods 7 to rotate in opposite directions, thereby driving the sliders 5 on the adjacent screw rods 7 to move in opposite directions. In other embodiments, synchronous belt transmission can be selected, but a synchronous pulley is also required to be installed on the screw rod 7. Compared with the preferred embodiment, the structure is slightly complicated, but it can achieve the purpose of driving the synchronous transmission of each screw rod 7.

[0024] As a preferred embodiment, the driving device is a motor 9, which is connected to the corresponding screw rod 7 through a reducer 10. The motor 9 has a good starting torque, can start quickly and drive the device to operate. In addition, the motor 9 is easy to operate and can achieve precise control. The reducer 10 can reduce the output speed of the motor 9 and increase the output torque, so that the motor 9 can run at a more efficient speed, reducing the loss in the energy transfer process, and the matching structure of the motor 9 and the reducer 10 is compact and occupies less space; the reducer 10 is connected to the screw rod 7 located in the middle of the length direction of the support rod 2 among the screw rods 7, and the reducer 10 is connected to the screw rod 7 in the middle position so that the load on both sides of the screw rods 7 when rotating synchronously can be uniform and the transmission path can be shortened. In other embodiments, for example, a cylinder or other pneumatic components can be selected, which have a simple and light structure. Although the movement speed of the cylinder is easily affected by the change of load, it can also provide driving power for the device.

[0025] As a preferred embodiment, a fixing rod 11 is fixedly connected between the two support rods 2, and each guide rod 4 is located in the space enclosed by the fixing rod 11 and the support rod 2. A fixing block 12 for fixing the position of the cable 3 is provided on the fixing rod 11, and a ring-shaped component 6 for the cable 3 to pass through is provided on the fixing block 12. The fixing block 12 and the fixing rod 11 are mainly used to fix the cable 3 at a fixed position that is convenient for the cable 3 to output and connect to the charging gun. The fixing block 12 has high strength and wear resistance, and can withstand long-term friction of the cable 3 and the weight of the cable 3.

[0026] As a preferred embodiment, Figure 5As shown, the slider 5 and the annular member 6 thereon, as well as the fixed block 12 and the annular member 6 thereon, are rotationally matched to adapt to the deflection of the cable 3. During the movement of the slider 5, the cable 3 passing through the annular member 6 will change its direction of travel accordingly, and the rotating annular member 6 can rotate as the direction of the cable 3 changes, so as to avoid deformation or entanglement of the cable 3 in this process, and also to avoid local wear of the cable 3 and reduce its service life; the slider 5 and the annular member 6 thereon, as well as the fixed block 12 and the annular member 6 thereon, are rotationally matched through the rotating shaft 13 provided on the corresponding annular member 6, respectively. The rotating shaft 13 has the characteristics of high rotation stability, and the rotating shaft 13 has a simple structure and is easy to install and maintain. In other embodiments, it is set as a fixed connection, which may cause local wear to the cable 3 at the component position. Although the annular member 6 cannot rotate, it does not affect its use as a component for the cable 3 to pass through, and regular inspection and maintenance are sufficient.

[0027] As a preferred embodiment, Figure 1 As shown, only 1 / 2 of the length of each screw rod 7 is provided with an external thread section 14, and the threads of adjacent screw rods 7 are located at different ends of the two. Only half of the screw rod 7 is provided with an external thread section 14, which can reduce the processing amount of the thread, thereby reducing the manufacturing cost, and at the same time prevent the slider 5 from reversing beyond the predetermined position. The slider 5 moves back and forth between the two ends of the external thread section 14 of the screw rod 7, that is, between the middle position of the screw rod 7 and the end of the screw rod 7. The thread positions of two adjacent screw rods 7 are opposite, so that the corresponding slider 5 on the screw rod 7 can be moved in the opposite direction and the slider 5 can be moved the maximum distance in a limited space, thereby better realizing the retraction and storage of the cable 3 and saving space.

[0028] As a preferred embodiment, Figure 5As shown, the slider 5 includes a support platform 15 at the top and a screw sleeve 16 at the bottom that cooperates with the corresponding screw rod 7. The length of the screw sleeve 16 is half of the size of the support platform 15 in the corresponding direction. In the length direction of the screw sleeve 16, the annular member 6 is located in the middle of the support platform 15. The support platform 15 part of the slider 5 is mainly used to support the annular member 6 for passing the cable 3, and is used to bear the weight of the cable 3 with good bearing performance to ensure the stability of the cooperation between the slider 5 and the screw rod 7; the screw sleeve 16 and the screw rod 7 are matched by threads. This connection method is firm and reliable and can effectively prevent the slider 5 from loosening and falling off, which can improve the stability of the device during operation, and the threaded matching has the effect of efficient transmission. The length of the screw sleeve 16 is half of the support platform 15, which can ensure that when the slider 5 moves to the end of the external threaded section 14 in the middle position of the screw rod 7 through the screw sleeve 16, the annular member 6 on the support platform 15 is in the middle position of the screw rod 7, which is convenient for ensuring that the moving distance of the cable 3 between the two sliders 5 is maximized. In other embodiments, the size of the threaded sleeve 16 at the bottom of the slider 5 is consistent with the support platform 15, and the external threaded section 14 is extended on the screw rod 7 by half the distance of the corresponding direction dimension of the screw rod 7 and the slider 5, which can also ensure that the annular component 6 is in the middle position of the screw rod 7.

[0029] The specific use process of the wire storage device of the invention is as follows: during the wire collection process, Figure 3 As shown, the synchronous gear 8 is driven by the reducer 10 and the motor 9, and the meshing rotation directions of the two adjacent synchronous gears 8 are opposite, so the rotation directions of the two adjacent screw rods 7 are opposite. Under the action of the thread transmission, the slider 5 moves from the middle position to the end of the screw rod 7 along the external thread segment 14 of the screw rod 7. The cables 3 between the screw rods 7 are in an "S" shape and the screw rods 7 drive the slider 5 to rotate synchronously, completing the collection of the cables 3 and storing them in the wire storage rack 1 waiting for the next use; on the contrary, during the wire release process, as Figure 4 As shown, the slider 5 moves from the end of the screw rod 7 to the middle of the screw rod 7 on the external threaded section 14 of the screw rod 7, and the distance of the cable 3 exposed outside the wire storage rack 1 becomes longer, thereby realizing the wire release and charging process.

The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the contents of the description and drawings of the present invention should also be included in the protection scope of the present invention.
