A cable reel device for a power distribution cabinet in an electric vehicle charging station

Abstract

This utility model discloses a cable winding device for a power distribution cabinet in an electric vehicle charging station, relating to the technical field of cable winding devices. It includes a power distribution cabinet, a cable winding structure, a fixed structure, and a moving structure. First, a second motor is started, which drives a lead screw to rotate. Since the lead screw is threadedly connected to the moving block, and the slide groove is slidably connected to the slide frame, the rotation of the lead screw is converted into horizontal movement of the cable winding structure, causing the circular plate and the cable winding roller to gradually move out of the power distribution cabinet, thus facilitating the subsequent cable winding operation. The charging cable is placed in the groove, and then an electric push rod is activated, causing the rubber pad on the other side of the arc-shaped pressure block to press tightly against the cable surface. The rubber pad is soft and has good elasticity and friction, which not only allows it to tightly adhere to the cable surface through deformation, enhancing the cable's fixation effect and preventing the cable from loosening or shifting during winding, but also avoids direct rigid contact between the arc-shaped pressure block and the cable, preventing wear and scratches on the cable sheath, thus protecting the cable.

Description

Technical Field

[0001] This utility model relates to the field of wire winding device technology, specifically a wire winding device for a power distribution cabinet used in electric vehicle charging stations. Background Technology

[0002] Electric vehicles (EVs) are vehicles powered by an onboard power source, driven by an electric motor, and that meet all road traffic and safety regulations. Compared to traditional gasoline-powered vehicles, they are characterized by low energy consumption and low pollution, making them an important means of transportation to address energy shortages and environmental pollution. EV charging stations, similar to gas stations, provide power to EVs. Their main function is to convert electrical energy from the grid into chemical energy from the EV's battery, replenishing its power and ensuring continuous operation. During the charging process, the charging cable is an essential component, connecting the charging station's equipment to the EV. The charging interface of a vehicle is responsible for transmitting electrical energy from the charging station to the battery of the electric vehicle. However, if the charging cable is not coiled up after use, it will cause many problems, such as: the loose cable is easily run over by passing vehicles, stepped on or dragged by pedestrians, which will lead to wear and tear on the outer sheath and damage to the internal wire core. This will not only shorten the service life of the cable, but may also cause safety hazards such as leakage. Moreover, the messy stacked cable will occupy the space of the charging station, affect the entry and exit of vehicles and the passage of people, and may even cause people to trip, reducing the operational safety of the charging station. Therefore, those skilled in the art have provided a cable coiling device for the power distribution cabinet of electric vehicle charging station to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this utility model is to provide a cable winding device for a power distribution cabinet in an electric vehicle charging station, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A cable winding device for a power distribution cabinet in an electric vehicle charging station includes a power distribution cabinet, a cable winding structure, a fixed structure, and a movable structure. A groove is provided on the upper part of one side of the power distribution cabinet, and the movable structure is fixedly connected in the groove. Two slides are fixedly connected to the bottom wall of the power distribution cabinet, and the cable winding structure is slidably connected on the slides. The fixed structure is fixedly connected to the cable winding structure.

[0006] As a further embodiment of this utility model: the winding structure includes a winding box, a slide groove, a first motor, a driving gear, a driven gear, a groove, a circular plate, a winding roller, and a moving block. The bottom of the winding box has two slide grooves that are corresponding to the slide frame. The slide grooves are slidably connected to the slide frame. The first motor is fixedly connected to the bottom wall of the winding box.

[0007] As a further embodiment of this utility model: a round shaft is fixedly connected to the power output shaft of the first motor, a driving gear is fixedly connected to the side of the round shaft away from the first motor, a driven gear is meshed with the side of the driving gear, a rotating shaft is fixedly connected to the driven gear, a winding roller is fixedly connected to the side of the winding box on one side of the rotating shaft, and the rotating shaft is rotatably connected to the winding box.

[0008] As a further embodiment of this utility model: a circular plate is fixedly connected to the side of the winding roller away from the winding box, a groove is provided on the shaft arm of the winding roller, a movable block is fixedly connected to the top of the winding box, and a second cabinet door is hinged to one edge of the winding box.

[0009] As a further embodiment of this utility model: the fixing structure includes a fixing block, an electric push rod, a connecting block, an arc-shaped pressure block and a rubber pad. The electric push rod is fixedly connected to the bottom of the fixing block, the power output end of the electric push rod is fixedly connected to the connecting block, the arc-shaped pressure block is fixedly connected to the side of the connecting block away from the electric push rod, and the rubber pad is fixedly connected to the other side of the arc-shaped pressure block.

[0010] As a further embodiment of this utility model: the moving structure includes a second motor, a rotating shaft and a lead screw. The power output shaft of the second motor is fixedly connected to the rotating shaft. The rotating shaft extends through one side of the distribution cabinet away from the second motor and into its interior, and is fixedly connected to the lead screw. The rotating shaft and the lead screw are rotatably connected to the distribution cabinet.

[0011] As a further embodiment of this utility model: the lead screw on the movable structure is threadedly connected to the movable block on the winding structure, and a circular groove adapted to the circular plate is opened in the middle of one side of the distribution cabinet, and the circular groove is movably connected to the circular plate.

[0012] As a further improvement of this utility model: a first cabinet door is hinged to one edge of the distribution cabinet, a handle is fixedly connected to one side of the first cabinet door, and anti-slip pads are fixedly connected to the four corners of the bottom of the distribution cabinet.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. During use, the second motor in the moving structure is started first. The power output shaft of the second motor drives the rotating shaft to rotate, which in turn drives the lead screw to rotate synchronously. Since the lead screw is threadedly connected to the moving block on the winding structure, and the slide groove at the bottom of the winding box is slidably connected to the slide frame on the bottom wall of the distribution cabinet, the rotation of the lead screw will be converted into the horizontal movement of the winding structure, so that the circular plate and the winding roller shaft gradually move out of the distribution cabinet, thus facilitating the subsequent winding work. At this time, the circular plate moves synchronously in the circular groove of the distribution cabinet to ensure the stability of the movement process.

[0015] 2. After the circular plate and winding roller are completely removed from the distribution cabinet, place the charging cable in the groove of the winding roller. Then, start the electric push rod of the fixed structure. The electric push rod extends and moves the connecting block and the arc-shaped pressure block downward, so that the rubber pad on the other side of the arc-shaped pressure block is in close contact with the cable surface. The rubber pad is soft and has good elasticity and friction. It can not only fit tightly with the cable surface through deformation, but also enhance the fixing effect of the cable and prevent the cable from loosening or shifting during the winding process. It can also avoid the arc-shaped pressure block and the cable from directly rigidly contacting each other, which would cause wear and scratches on the cable sheath, thus protecting the cable. At the same time, it can also reduce the friction noise between the cable and the pressure block during winding, thereby firmly fixing the cable on the winding roller.

[0016] 3. Then the first motor of the winding structure is started. The power output shaft of the first motor drives the round shaft to rotate, which in turn drives the drive gear to rotate. The drive gear meshes with the driven gear, causing the driven gear to drive the rotating shaft and the winding roller shaft to rotate. During the rotation of the winding roller shaft, the cable is neatly wound on its shaft arm, realizing the winding operation.

[0017] 4. After the winding is completed, reverse the second motor to drive the rotating shaft and lead screw to rotate in the opposite direction, so that the winding structure moves along the slide into the distribution cabinet until the circular plate and winding roller return to the initial position; the inside of the distribution cabinet can be inspected by opening the first cabinet door with the handle. When the winding structure needs maintenance, the second cabinet door on one side of the winding box can be opened for operation. Attached Figure Description

A groove 4 is formed on the upper part of one side of the power distribution cabinet 1, and the movable structure 7 is fixedly connected within the groove 4. Two slides 8 are fixedly connected to the bottom wall of the power distribution cabinet 1, and the cable winding structure 5 is slidably connected to the slides 8. The fixed structure 6 is fixedly connected to the cable winding structure 5. The lead screw 73 on the movable structure 7 is threadedly connected to the moving block 59 on the cable winding structure 5. A circular groove 9, adapted to a circular plate 57, is formed in the middle of one side of the power distribution cabinet 1. 9 is movably connected to the circular plate 57; a first cabinet door 3 is hinged to one edge of the distribution cabinet 1, and a handle is fixedly connected to one side of the first cabinet door 3. Anti-slip pads 2 are fixedly connected to the four corners of the bottom of the distribution cabinet 1. By opening the first cabinet door 3 through the handle, the inside of the distribution cabinet 1 can be inspected; the winding structure 5 includes a winding box 51, a slide groove 52, a first motor 53, a driving gear 54, a driven gear 55, a groove 56, a circular plate 57, a winding roller 58, and a moving block 59. The bottom of the winding box 51 has two slide grooves 52 that correspond to the slide frame 8. 52 is slidably connected to the carriage 8. A first motor 53 is fixedly connected to the bottom wall of the winding box 51. A round shaft is fixedly connected to the power output shaft of the first motor 53. A drive gear 54 is fixedly connected to the side of the round shaft away from the first motor 53. A driven gear 55 is meshed with the side of the drive gear 54. A rotating shaft is fixedly connected to the driven gear 55. One side of the rotating shaft passes through one side of the winding box 51 and is fixedly connected to a winding roller 58.

A section is opened on the shaft arm of the winding roller 58. The top of the winding box 51 is fixedly connected to the groove 56 and the movable block 59. A second cabinet door is hinged to one side edge of the winding box 51. When the first motor 53 is started, the power output shaft of the first motor 53 drives the round shaft to rotate, which in turn drives the drive gear 54 to rotate. The drive gear 54 meshes with the driven gear 55, which drives the rotating shaft and the winding roller shaft 58 to rotate. During the rotation of the winding roller shaft 58, the cable is neatly wound on its shaft arm to realize the winding operation.

[0028] Example 2

[0029] Reference Figure 4-6This embodiment is based on the previous embodiment, but differs in that the fixing structure 6 includes a fixing block 61, an electric push rod 62, a connecting block 63, an arc-shaped pressure block 64, and a rubber pad 65. The electric push rod 62 is fixedly connected to the bottom of the fixing block 61, and the connecting block 63 is fixedly connected to the power output end of the electric push rod 62. The arc-shaped pressure block 64 is fixedly connected to the side of the connecting block 63 away from the electric push rod 62, and the rubber pad 65 is fixedly connected to the other side of the arc-shaped pressure block 64. The charging cable is placed on the winding roller. Within the groove 56 of 58, the electric push rod 62 is then activated. The electric push rod 62 extends, causing the connecting block 63 and the arc-shaped pressure block 64 to move downwards. This causes the rubber pad 65 on the other side of the arc-shaped pressure block 64 to press tightly against the cable surface. The rubber pad 65 is soft and has good elasticity and friction. It can both deform to tightly adhere to the cable surface, enhancing the cable's fixation and preventing loosening or shifting during cable winding, and also prevent direct rigid contact between the arc-shaped pressure block 64 and the cable, thus avoiding wear and scratches to the cable sheath and protecting the cable. The cable serves to reduce friction noise between the cable and the pressure block during winding, thus firmly fixing the cable to the winding roller 58. The moving structure 7 includes a second motor 71, a rotating shaft 72, and a lead screw 73. The power output shaft of the second motor 71 is fixedly connected to the rotating shaft 72. The side of the rotating shaft 72 away from the second motor 71 passes through one side of the distribution cabinet 1 and extends into its interior, and is fixedly connected to the lead screw 73. The rotating shaft 72 and the lead screw 73 are rotatably connected to the distribution cabinet 1. When the second motor 71 is started, the second motor... The power output shaft of 71 drives the rotating shaft 72 to rotate, which in turn drives the lead screw 73 to rotate synchronously. Since the lead screw 73 is threadedly connected to the moving block 59 on the winding structure 5, and the slide groove 52 at the bottom of the winding box 51 is slidably connected to the slide frame 8 on the bottom wall of the distribution cabinet 1, the rotation of the lead screw 73 will be converted into the horizontal movement of the winding structure 5, so that the circular plate 57 and the winding roller shaft 58 gradually move out of the distribution cabinet 1, thereby facilitating the subsequent winding work. At this time, the circular plate 57 moves synchronously in the circular groove 9 of the distribution cabinet 1 to ensure the stability of the movement process.
