[0002] Currently, when charging pure electric vehicles, the equipment used for charging includes charging piles, mobile charging carts, and mobile charging and swapping integrated AGVs. These devices all have charging gun cables, which are generally about 5 meters long. When charging is finished, some charging gun cables are placed directly on the ground, while others are coiled up and hung on the charging pile or mobile charging cart, which affects the aesthetics and is not conducive to the preservation of the charging gun cables.

[0003] To address this problem, there is an urgent need for a cable winder that can automatically wind up the charging gun cable.

[0004] In the prior art, there are also related patents on charging gun cable reels. For example, an automatic charging pile cable reeling and unloading device is disclosed in publication number CN205973316U. This patent uses an IC card door lock to retrieve the charging gun, but it cannot automatically open and close the operating door. At the same time, this patent cannot guide the direction of the charging gun cable.

[0005] The charging gun reel disclosed in CN221720208U does not have a closed shell, making it impossible to store the charging gun cable or switch it on and off during use. At the same time, it cannot provide directional guidance for reeling in the charging cable. Utility Model Content

Detailed Implementation

[0047] The present invention will be further described below with reference to the accompanying drawings.

[0048] See Figures 1 to 5 Specific Embodiment 1: A charging gun cable reel includes a reel 203 for winding a charging gun cable 210, and a base 201. The reel 203 is rotatably mounted on the base 201. A rotary drive mechanism for driving the reel 203 to rotate is mounted on the base 201. A cable-blocking mechanism for limiting the charging gun cable 210 is also mounted on the base 201, and the cable-blocking mechanism is installed on the periphery of the reel 203. The cable-blocking mechanism may include at least one of a roller 212 and a cable-blocking wheel 213. The roller 212 and the cable-blocking wheel 213 are rotatably mounted on the base 201. The outer wall of the roller includes a concave arc-shaped curved surface. The cable guide wheel chassis 201 is also equipped with a first correction mechanism 214 and a second correction mechanism 215 for adjusting the extension direction of the charging gun cable 210. The charging gun cable 210 passes sequentially along its length through the cable reel 203, the first correction mechanism 214, and the second correction mechanism 215 to connect with the charging gun head 220. The first correction mechanism 214 guides the charging gun cable 210 to extend outward from the cable reel 203. The second correction mechanism 215 guides the extension direction of the charging gun cable 210 to be vertically downward. This invention, through the provision of the first correction mechanism 214 and the second correction mechanism 215, facilitates the vertical downward extension of the charging gun head 220.

[0049] The device also includes a cover 101, which, together with the chassis 201, forms a chamber for housing the cable reel 203. The bottom of the cover 101 has an opening for the charging gun head 220 to extend from, located directly below the second correction mechanism 215. A sliding door 102 for sealing the opening is slidably connected to the chassis 201. A linear telescopic mechanism for driving the sliding door 102 to move linearly is mounted on the cover 101. The linear telescopic mechanism can be a push rod 104. A position sensor 103 for sensing the position of the sliding door 102 is mounted on the cover 101. The position sensor 103 can be an infrared proximity switch. Two position sensors 103 are provided, one in the open state and the other in the closed state of the sliding door 102. This invention optimizes the structure of the cable reel, facilitating the storage of the charging gun head 220 through the opening and closing of the sliding door 102. During charging, the charging gun head 220 extends downward from the opening by opening the sliding door 102. When charging is finished, the charging gun head 220 is retracted upward from the opening and the sliding door 102 is closed.

[0050] The first correction mechanism 214 includes adjacent guide wheels, with a gap between the two guide wheels for the charging gun cable 210 to pass through. The outer wall of the guide wheel includes a concave arcuate surface.

[0051] The second correction mechanism 215 includes at least two sets of limiting wheel groups arranged from top to bottom. Each limiting wheel group includes two limiting wheels arranged side by side, with a gap between the two limiting wheels for the charging gun cable 210 to pass through. The central axis directions of the limiting wheels in adjacent limiting wheel groups are different. There are two sets of limiting wheel groups, and the central axes of the limiting wheels in the two sets of limiting wheel groups are perpendicular to each other.

[0052] The second correction mechanism 215 includes a mounting frame, on which a limit wheel is rotatably mounted.

[0053] The second correction mechanism 215 includes a mounting bracket, below which is a monitoring mechanism for sensing whether the charging gun head 220 is properly retracted. The monitoring mechanism includes a baffle 218 for the charging gun head 220 to press against the baffle 218 and a sensor 216 for sensing the baffle 218. A bolt 219 is connected to the bottom of the mounting bracket, and the baffle 218 is slidably connected to the bolt 219. A spring 217 is fitted on the bolt 219, with one end of the spring 217 abutting against the mounting bracket and the other end abutting against the baffle 218. When the reel 203 winds up the charging gun cable 210, and the charging gun head 220 presses against the baffle 218, the sensor senses the baffle 218, thus determining that the charging gun head 220 is properly retracted.

[0054] The rotary drive mechanism includes a drive motor 204, with a gear 206 mounted on the power output shaft of the drive motor 204. An external gear 207 meshing with the gear 206 is provided on the outer wall of the winding reel 203. The drive motor 204 is mounted on a motor bracket 205. The motor bracket 205 is mounted on a chassis 201.

[0055] The reel 203 is rotatably mounted on the chassis 201 via the slewing support 202.

[0056] An electric slip ring bracket 209 is installed on the reel 203, and an electric slip ring 208 is installed on the electric slip ring bracket 209. The charging gun cable 210 is connected to the external power supply line through the electric slip ring 208. A lead-in port for connecting the electric slip ring 208 to the external power supply line is provided on the chassis 201.

[0057] The chassis assembly 2 is a chassis 201 equipped with a winding reel 203, a rotary drive mechanism, a roller 212, a guide wheel 213, a first straightening mechanism 214, and a second straightening mechanism 215.

[0058] The cover assembly 1 is a cover body 101 equipped with a sliding door 102, a linear telescopic mechanism and a position sensor 103.

[0059] The chassis assembly can be installed on a wheeled AI battery swapping robot or on a mobile charging vehicle.

[0060] When the chassis assembly is installed on other equipment, the cover assembly 1 may not need to be installed.

[0061] The working principle of this device for wire take-up and feed is as follows:

[0062] When the reel receives a charging command, the push rod 104 installed on the cover 101 drives the sliding door 102 to open. The position sensor 103 determines the position of the sliding door and waits until the sliding door is fully open.

[0063] The drive motor 204 drives the gear 206 to rotate. The gear 206 meshes with the external gear 207, which drives the winding reel 203 to rotate. The winding reel 203 is mounted on the slewing support 202. The winding reel 203 drives the charging gun cable 210. The charging gun cable 210 is prevented from falling off the winding reel 203 by the combined obstruction of the roller 212 and the cable guide wheel 213. The charging gun cable 210 passes through the first straightening mechanism 214 and the second straightening mechanism 215. The charging gun head extends out of the winding reel to charge the user.

[0064] After charging is complete, the drive motor 204 rotates in the opposite direction to retract the charging gun cable. When it is about to be fully retracted, the charging gun head presses against the baffle 218, and the baffle 218 compresses the spring 217. When the baffle 218 is pressed, the baffle contacts the sensor 216 and then sends a signal, and the drive motor 204 stops rotating, ending the gun retraction.

[0065] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
