[0032] Example

[0033] like Figure 1 to Figure 2 As shown, an electric vehicle charging pile automatic retractable charging gun cable protection device provided by an embodiment of the present invention specifically includes a winding bracket 100 installed on the side of the charging pile, and a winding drum 200 is rotatably installed on the winding bracket 100, and the cable on the charging gun is wound up by the winding drum 200 to avoid the cable scattered on the ground after use from being damaged, or even causing safety hazards. A limited cable bracket 300 is also provided on the winding bracket 100, and the limited cable bracket 300 is used to protect the surface of the cable during the winding process to prevent the surface of the cable from being worn during the guiding and winding process, wherein the limited cable bracket 300 is located at opposite sides of the winding drum 200, and a driving part 400 is also provided on the winding bracket 100, and the output end of the driving part 400 is connected to the winding drum 200, and the driving part 400 drives the rotation of the winding drum 200 to realize the winding operation of the cable of the charging gun;

[0034] The cable storage system structure design of traditional charging piles is relatively complex, with many components, which increases the difficulty of production, installation and maintenance, resulting in an increase in service costs. Moreover, since some charging piles use high-end materials and complex mechanical designs, the overall manufacturing and maintenance costs are high, which reduces the acceptability of ordinary users, especially in the low-price market. In addition, the current manual cable retraction method is not only time-consuming and laborious, but users need to manually retract the cable after charging, which wastes time and increases the inconvenience of operation, reducing the efficiency of charging piles. Existing charging piles lack effective protection design in cable management. Cables are often placed randomly after use and are easily affected and damaged by the external environment, especially in bad weather. Cables exposed to the outside increase the risk of wear and failure. Cables scattered on the ground may cause safety hazards such as tripping, especially in public places. This situation will cause potential dangers to passers-by and drivers. The design of most charging piles does not take into account the user's operating experience, and the way to store cables is not humane enough. Users may face difficulties in use in different situations (such as at night or rainy days).

[0035] In view of the above, it is extremely important to design a protective device for the charging gun cable to facilitate automatic reeling after use, and to avoid secondary damage to the cable during the reeling process.

[0036] It is worth mentioning that a control module 500 is also included, and the control module 500 is installed at the bottom of the cable winding support 100 and is electrically connected to the driving unit 400, and the opening and closing of the driving unit 400 are controlled by the control module 500. It is worth mentioning that the control module 500 also supports a wireless connection mode, so that the user can conveniently and effectively control the retraction and extension of the cable at any position, thereby improving the user's operating experience.

[0037] The charging gun cable protection device realizes automatic reeling of the charging gun cable by driving the reel-in disk to rotate through the driving unit 400, which can effectively prevent the cable from scattering, reduce the risk of being crushed by vehicles due to random scattering, and ensure the safety of users and equipment.

[0038] Preferably, the cable reel 100 includes a mounting plate 110, a base shell 120 and a support plate 130, wherein the base shell 120 is mounted on the mounting plate 110, and the support plates 130 are mounted on opposite sides of the base shell 120. The cable reel 100 is in a herringbone structure as a whole, which provides good stability for the installation of the cable reel 200, ensuring that the cable reel will not tilt or shake during operation.

[0039] In some preferred embodiments, the cable reel 200 includes a rotating shaft, a cable drum 210 and a limiting plate 220 arranged at opposite ends of the cable drum 210, the cable drum 210 is installed on the rotating shaft, and the rotating shaft is rotatably installed on the support plate 130 through a bearing, and a charging gun cable outlet hole is provided on the cable drum 210, one end of the charging gun cable 230 passes through the charging gun cable outlet hole, and the other end passes through the limiting cable bracket 300, and the rest is wound on the cable drum 210.

[0040] In some preferred embodiments, the driving unit 400 is a winding motor, and the output end of the winding motor is connected to the rotating shaft. The winding motor drives the rotating shaft to rotate, thereby driving the winding drum 210 to reel the charging gun cable 230. It is worth mentioning that a charging gun 240 is provided on one end of the charging gun cable 230 that passes through the limit cable bracket 300.

[0041] In some preferred embodiments, the control module 500 is installed in the base shell 120 and is electrically connected to the winding motor via a motor cable 410. The control module 500 is used to control the opening and closing of the winding motor.

[0042] In some preferred embodiments, the limiting cable bracket 300 includes a limiting mounting plate 310, a connecting mounting plate 320 and a transition assembly 330. The connecting mounting plates 320 are arranged on the opposite ends of the limiting mounting plate 310. The limiting mounting plate 310 is installed on the support plate 130 through the connecting mounting plate 320. The limiting mounting plate 310 is provided with a limiting opening 311. The transition assembly 330 is arranged around the limiting opening 311 to prevent the surface of the charging gun cable 230 from contacting the edge during the winding process, causing scratches / scratches, thereby damaging the surface of the charging gun cable 230.

[0043] Furthermore, the transition assembly 330 includes a first transition drum 331 and a second transition drum 332, the first transition drum 331 is rotatably mounted on the upper and lower sides of the limit opening 311, and the second transition drum 332 is rotatably mounted on the left and right sides of the limit opening 311. The setting of the transition assembly 330 can effectively prevent the wear of the charging cable, and the limit opening 311 can also prevent the excessive retraction of the charging gun cable 230, ensuring the safety and effectiveness of the cable during use (because the overall volume of the charging gun 240 is larger than the limit opening 311, when the cable part of the charging gun 240 is reeled up, the charging gun 240 will be restricted outside the limit opening 311 to limit the continued retraction of the charging gun cable 230).

[0044] Preferably, a control switch 131 is also provided on the support plate 130, and the control switch 131 is electrically connected to the control module 500. A sensor is also provided on the limit mounting plate 310, and the sensor is electrically connected to the control module 500, and the sensing end of the sensor is facing the limit opening 311. The design of the sensor can prevent the charging gun cable 230 from being over-reeled. The user can control the opening and closing of the winding motor through the control switch 131, so as to conveniently adjust the retracted length of the charging gun cable 230. During the retracting process, the sensor is used to ensure that the charging gun cable 230 will not be over-stretched or retracted during the retracting process, thereby protecting the integrity of the cable.

[0045] In summary, the present invention provides an automatic retractable charging gun cable protection device for an electric vehicle charging pile, which realizes the automatic retracting operation of the charging gun cable by driving the reel to rotate through a driving part, can effectively prevent the cable from scattering, reduce the risk of being crushed by vehicles due to random scattering, and ensure the safety of users and equipment; the charging gun cable protection device provided by the present invention can easily control the retraction and release of the cable through a control module, simplifies the operation process, and improves the use experience; the charging gun cable protection device provided by the present invention is provided with a limited cable bracket, and the limited cable bracket is provided with a transition component, through which the wear on the surface of the cable during the retraction process can be reduced, thereby extending the service life of the cable; the charging gun cable protection device provided by the present invention has a simple structure, is convenient and practical, and can realize the work of retracting the charging gun cable after use through close manual control or remote wireless control, eliminating the tediousness and time-consuming of traditional manual retraction, improving the retraction efficiency after charging is completed, and at the same time, it can also provide real-time protection for the charging gun cable.

[0046] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
