Description

TECHNICAL FIELD

[0001] The utility model relates to new energy charging pile technical field, concretely is a new energy charging pile automatic take -up mechanism. BACKGROUND

[0002] With the wide application of new energy charging pile, the storage and management of charging pile cable are increasingly apparent. The traditional winding structure is widely used in cable storage device, which has the advantages of effectively storing cable neatly, saving space and facilitating storage. However, the traditional winding structure has some disadvantages in the working process of the cable, especially in the high current charging process, which may cause current eddy current phenomenon in the cable, and then produce heating effect, affecting the safety and working performance of the cable.

[0003] Specifically, the traditional cable winding structure mainly relies on the tight winding of cable in the winding process. This tight winding method may cause eddy current in the cable during charging, especially when high current flows through the cable. The eddy current effect may cause the metal conductor in the cable to be subjected to different electromagnetic forces, thereby generating heat. This heat accumulation on the surface and inside of the cable may cause the following problems:

[0004] Cable overheating: due to the existence of eddy current, the heat generated in the working process of the cable cannot be effectively dissipated, resulting in local overheating of the cable. The high temperature of the cable may damage the insulation layer of the cable itself, reducing its service life.

[0005] Cable damage: high temperature may cause aging and damage of cable materials, especially the insulation layer, and even cause short circuit and other serious safety accidents, especially when charging for a long time or high current charging, the current eddy current effect is more obvious.

[0006] Energy efficiency reduction: the heating phenomenon caused by current eddy current is the waste of energy, which reduces the overall energy efficiency in the charging process and affects the charging efficiency and device performance.

[0007] Therefore, the existing problems are studied and improved, and a new energy charging pile automatic take-up mechanism is provided to solve the existing problems, aiming to solve the problems and improve the practical value through the technology. INVENTION CONTENTS

Its main purpose is used in new energy charging pile, automatically stores cable neatly, and ensures that cable maintains good working condition in the working process, so as to improve the use efficiency and safety of charging equipment.

[0009] The technical scheme of the utility model can effectively solve the problems of eddy current effect, heating effect and cable damage caused by non-standard cable winding during high-current charging of the traditional cable storage device. Through the innovative winding structure design combined with electric drive control, automatic winding and unwinding of the cable is realized, the cable is kept neat, smooth and unwound during charging, and the occurrence of eddy current and heating phenomenon is avoided.

[0010] Specifically, the new energy charging pile automatic winding mechanism comprises the following key parts:

[0011] The pile body is the core supporting component of the device and is mainly used for fixing the cable storage device. The vertical plate frame is fixedly installed on the surface of the pile body and is used for supporting the output end of the cable. The output end of the vertical plate frame is connected with the cable, and the cable is wound and unwound through the winding device.

[0012] Connecting rod: the winding assembly is composed of multiple connecting rods to form an X-shaped structure, ensuring that the cable is evenly distributed when winding to prevent the cable from being twisted or damaged due to uneven pressure. Wire sleeve: a wire sleeve is installed at the end of each connecting rod, through which the cable smoothly passes, reducing friction and providing a stable path. Guide wheel body: the guide wheel body is used to guide the winding and unwinding of the cable, cooperating with the winding and unwinding of the cable to ensure smooth flow of the cable and reduce friction resistance, improving durability.

[0013] Inner core: the inner core is provided inside the cable to enhance the structural strength of the cable and maintain the shape of the cable during winding and unwinding. The inner core can ensure that the cable remains straight during charging, avoiding irregular bending. Wear-resistant sleeve layer: the cable surface is covered with a wear-resistant sleeve layer to reduce friction with the guide wheel body, improve the wear resistance of the cable and prolong the service life.

[0014] The drive rod is an electric actuator structure installed on the surface of the vertical plate frame. The drive rod functions to automatically retract the winding assembly through electric control. Through electric drive, the cable can be smoothly retracted into the pile body, ensuring that the cable is stored neatly and avoiding occupation of external space by the cable.

[0015] The utility model has the advantages of:

[0016] 1. In the utility model, the winding assembly can automatically retract and keep the cable neat through the driving of the drive rod, without any annular structure to avoid the generation of eddy current during charging. The X-shaped structure formed by the two-by-two connection and rotation can ensure that the cable is evenly wound. This design avoids local accumulation or excessive winding of the cable, effectively reduces the friction, stretching and twisting of the cable, and prolongs the service life of the cable.

[0017] 2. The utility model discloses a cable line structure is strengthened to the inner muscle core, makes the cable line keep the shape in the process of storage and unfolding. This flexible design makes the cable not easy to be subjected to excessive stretching, oppression or breakage in the use process, avoids the damage of uneven stress of the cable in the traditional take-up structure.

[0024] To make the purpose, technical scheme and advantage of the utility model more clear and obvious, the utility model is explained in further detail below in combination with specific embodiments and with reference to the drawings. It should be explained that the embodiments of the utility model and the features in the embodiments can be combined mutually without conflict.

[0025] It is understood that these descriptions are only exemplary, and are not intended to limit the scope of the utility model.

[0026] The utility model discloses a new energy charging pile automatic take-up mechanism. Figures 1-4 Some embodiments of the utility model provide a new energy charging pile automatic take-up mechanism.

[0027] The new energy charging pile automatic take-up mechanism in the embodiment includes stake body 100, take-up assembly 200 and drive rod 300, and through reasonable structure design, ensures the automatic storage and unfolding of charging cable.

[0028] Stake body 100 is the core part of the device, is usually fixedly installed on the main body of charging pile, and the surface is fixedly installed with vertical plate frame 110 and is used for supporting the connection of cable line. The output end of vertical plate frame 110 is connected with cable line 120, and cable line 120 is stored and unfolded through take-up assembly.

[0029] Connecting rod 210: The cable winding assembly is composed of several connecting rods 210, which are connected to each other by connecting pins to form an X-shaped structure. This structure ensures that the cable 120 can be evenly distributed when stored, preventing cable twisting or damage caused by uneven pressure.

[0030] Wire sleeve 220: The end of each connecting rod 210 is equipped with a wire sleeve 220, which is connected to the surface of the connecting pin by rotating sleeve. The wire sleeve 220 provides a smooth channel for the cable 120, reducing friction loss during winding and unwinding;

[0031] The surface of the wire sleeve 220 is provided with a sleeve hole for the cable 120 to pass through.

[0032] Guide wheel body 230: The guide wheel body 230 is installed at the end of the connecting rod 210, used to guide and protect the winding and unwinding process of the cable 120. The surface of the guide wheel body 230 is designed as an arc-shaped smooth surface, reducing friction resistance and ensuring smooth passage of the cable 120 during winding and unwinding.

[0033] The inner surface of the cable 120 is embedded with an inner core 121, which enhances the strength of the cable and helps the cable maintain shape recovery ability. During winding and unwinding of the cable, the inner core can ensure that the cable remains straight, avoiding damage to the cable due to excessive bending during winding and unwinding.

[0034] The outer surface of the cable is provided with a wear-resistant sleeve layer 122, which reduces the friction between the cable and the surface of the guide wheel body 230, improves the durability of the cable, and prevents the cable surface from being worn.

[0035] The driving rod 300 adopts an electric actuator structure and is installed on the surface of the vertical plate frame 110. The driving rod automatically pushes the cable winding assembly 200 to retract. The driving rod realizes automatic operation of winding and unwinding through electric control, making the winding of the cable more convenient and avoiding the trouble of manual operation.

[0036] When the cable 120 needs to be retracted, the driving rod 300 will drive the cable winding assembly 200 to retract by electric drive, so that the cable 120 is neatly wound back to the vertical plate frame 110 area through the guide wheel body 230 and the wire sleeve 220, ensuring the neatness and safety of cable storage.

[0037] The working principle and use process of the utility model are as follows:

[0038] The cable 120 passes through the surface of the guide wheel body 230 in a zigzag manner through the cooperation of the guide wheel body 230 and the wire sleeve 220, and is connected to the charging head part. The connecting rod 210 is connected and rotated in pairs to form an X-shaped structure, ensuring uniform winding of the cable.

[0039] In the storage state, the cable 120 is tightly wound on both sides of the connecting rod 210, and by rotating the guide wheel body 230 and the wire sleeve 220, the cable 120 is wound back to the area of the vertical plate frame 110, keeping the storage neat.

[0040] When using charging, the operator can directly pull the cable 120 end to expand, keep the shape of the cable 120 through the inner core 121 of the flexible structure, and deform the cable 120 to facilitate the insertion of the charging head into the charging port of the new energy vehicle, so as to avoid the cable 120 from being wound in the charging current and generating eddy current heating. After charging is completed, the winding assembly 200 is driven to retract by the driving rod 300, the connecting rod 210 is pushed back to the original position, and the cable 120 is wound again to ensure the neatness and safety of the cable 120.

[0041] In the retraction process, the cable 120 is wound into the guide wheel body 230, and the wear-resistant sleeve layer 122 reduces the frictional resistance between the cable 120 and the surface of the guide wheel body 230, thereby improving the service life and wear resistance.

[0042] The inner core 121 in the cable 120 enhances the structural strength and shape recovery ability of the cable 120, and the winding device of the present application can more stably store the cable 120, avoiding damage to the cable during use.
