Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and more specifically, to a ceiling-mounted charging pile and a method for using the same. Background Art

[0002] An automotive charging pile, also known as an electric vehicle charging station or electric vehicle power supply equipment, is a device that provides electrical energy replenishment for electric vehicles or plug-in hybrid vehicles. The automotive charging pile is an important part of the electric vehicle industry chain, connecting the power grid and electric vehicles, and providing convenient and efficient charging services for electric vehicles.

[0003] For example, CN212242996U involves a ceiling-mounted charging pile, including a charging pile body, two symmetrically arranged pedestals, and a driving mechanism. The tops of the two pedestals are fixed on the ceiling of the garage. An arc-shaped substrate is arranged between the front sides of the two pedestals, and the central angle θ of the arc-shaped substrate is greater than 160°; the charging pile body is horizontally arranged, and the rear end of the charging pile body abuts against the front arc-shaped surface of the arc-shaped substrate and can perform circular motion along the arc-shaped surface; the axis of the virtual cylinder where the arc-shaped substrate surface is located is the same as the axis of the first rotating shaft.

[0004] The charging pile in the above patent can be installed on the ceiling of the garage. By driving the connecting rod device to rotate through a rotating shaft, the charging pile body rotates to a vertically downward state during use, which is convenient for personnel to charge, and the wiring can be carried out through the ceiling of the garage, avoiding the excavation of the foundation of the garage. However, the problem is that the space in the underground garage is limited, and the charging pile can only be installed in the space above the parking space. The charging pile in the above patent is used by rotating to a vertically downward state. If the indoor net height of the underground garage is small or the vehicle is a vehicle with a relatively high vehicle height, such as a van, the charging pile will be stuck by the vehicle ceiling during the rotation process, resulting in damage to the charging pile and the vehicle.

[0005] In order to avoid the charging pile being stuck by the vehicle ceiling during the retracting and extending use process, a ceiling-mounted charging pile and a method for using the same are proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide a ceiling-mounted charging pile and a method for using the same to solve the problems raised in the above background art.

[0007] To achieve the above object, one of the objects of the present invention is to provide a ceiling-mounted charging pile, including a ceiling assembly and a charging assembly arranged in the ceiling assembly; The ceiling assembly includes a ceiling suspension fixed on the basement roof and a translation frame slidably connected to the ceiling suspension; The charging component includes a flipping frame plate rotatably connected to the inner wall of the translation frame. A storage rack is slidably connected inside the flipping frame plate. A charger for charging is provided inside the storage rack. Shielding bodies for shielding the charging gun of the charger are provided on both sides of the storage rack. The flipping frame plate flips downward from the side away from the vehicle. During the process of the flipping frame plate flipping downward to release the charger, the angle between the flipping frame plate and the translation frame increases, driving the shielding body to move and expose the charging gun of the charger.

[0008] As a further improvement of this technical solution, plate openings for expansion bolts to pass through are provided at the four corners of the ceiling suspension. The ceiling suspension is fixed to the basement roof through expansion bolts. A translation frame is horizontally slidably connected to the ceiling suspension. A motor is provided at one end of the ceiling suspension. The motor controls the movement of the translation frame through a first lead screw provided. A corner roller is provided at the bottom of the other end of the ceiling suspension. The bottom surfaces of the translation frame, the flipping frame plate, and the storage rack are all in contact with the corner roller.

[0009] As a further improvement of this technical solution, sliding wheels are provided on both sides of the storage rack near the motor end. Corresponding displacement grooves are provided on the flipping frame plate. The sliding wheels are located in the displacement grooves. The storage rack and the flipping frame plate are slidably connected through the sliding wheels and the displacement grooves.

[0010] As a further improvement of this technical solution, the storage rack is of an overall "mouth" - shaped structure. The charger is located inside the central opening of the storage rack. The shielding body includes movable plates located inside both ends of the storage rack. The movable plates are in plug - in fit with the inside of both ends of the storage rack. Storage cavities for accommodating the charging gun are provided at both ends of the storage rack away from the motor end. The movable plates pass through the storage cavities. The movable plates are strip - shaped plates with plate grooves on their surfaces. The shape of the plate grooves matches the shape of the storage cavities. Angle transmission structures are provided at both ends of the storage rack near the motor end. The angle transmission structures are in transmission connection with the movable plates. The angle transmission structures drive the movable plates to move by using the change in the angle between the flipping frame plate and the translation frame.

[0011] As a further improvement of this technical solution, the angle transmission structure includes a hollow shaft rotatably connected to the inner wall of the storage rack. A sleeve is connected to one end of the movable plate near the hollow shaft. The hollow shaft is in threaded connection with the sleeve. A frame - side shaft is provided on the inner wall of the translation frame. The flipping frame plate rotates around the frame - side shaft. An inner shaft is rotatably connected to the inner wall of the flipping frame plate. One end of the inner shaft meshes with one end of the frame - side shaft. The other end of the inner shaft is connected to the hollow shaft.

[0012] As a further improvement of the technical solution, one end of the inner shaft away from the frame edge shaft is inserted and matched with the hollow shaft. A cross-shaped protrusion is provided on the surface of the inner shaft, and the inner shaft is clamped and matched with the hollow shaft through the provided cross-shaped protrusion.

[0013] As a further improvement of the technical solution, a second lead screw is rotatably connected to the inner wall of the end of the storage rack away from the motor. The second lead screw is threadedly connected to the movable plate. A reel body is provided in the storage cavity. The reel body includes a pair of concave wheels, and the concave wheels are rotatably connected to the inner wall of the storage cavity. One end of the second lead screw is engaged with the concave wheel.

[0014] As a further improvement of the technical solution, a wire winding body is further provided at one end of the flipping frame plate close to the motor. The wire winding body includes a reel rotatably connected to the inner wall of the flipping frame plate. The reel is connected to the inner wall of the flipping frame plate through a provided scroll spring. A pulling rope is wound on the reel, and one end of the pulling rope is connected to the surface of the storage rack.

[0015] A second object of this embodiment is to further provide a usage method for the above-mentioned ceiling charging pile, including the following steps: S1. The motor drives the first lead screw to drive the translation frame to horizontally slide along the ceiling suspension towards the head or tail of the vehicle until the bottom of the charging component is suspended and does not contact the corner roller. Under the action of the self-weight of the charging component, the flipping frame plate will flip downward from the side away from the vehicle. S2. When the flipping frame plate flips downward, the inner shaft engaged with the frame edge shaft rotates to drive the hollow shaft to drive the movable plate to move along the inner wall of the storage rack until the plate groove just aligns with the storage cavity, and the user can take out the charging gun from the storage cavity to charge the vehicle. S3. The motor drives the first lead screw to reverse, and then drives the translation frame to horizontally slide and reset along the ceiling suspension, and pulls the flipping frame plate to reverse flip with the corner roller as the inflection point. S4. The movable plate drives the second lead screw to reverse, and then drives the concave wheel to reverse through the second lead screw to retract the cable into the storage cavity. Under the action of the scroll spring, the reel reverses to drive the storage rack and the charger to return to their original positions through the pulling rope.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In the ceiling-mounted charging pile and its usage method, the ceiling suspension is set on the basement ceiling above the basement parking space. The first lead screw is rotated by a motor, and then the translation frame is driven to slide horizontally along the ceiling suspension towards the head or tail of the vehicle. When the translation frame slides, the charging component is driven to move synchronously until the bottom of the charging component is suspended and does not contact the corner roller. At this time, under the action of the self-weight of the charging component, the flipping frame plate will flip downward from the side away from the vehicle. By moving the device to a position away from the vehicle and then flipping it downward, it is possible to avoid problems such as vehicle damage and device failure caused by the device being stuck by the vehicle ceiling during flipping.

[0017] 2. In the ceiling-mounted charging pile and its usage method, during the downward flipping process of the flipping frame plate, under the action of the self-weight of the storage rack and the charger, the sliding wheels of the storage rack slide down to the bottom along the displacement groove. At this time, the storage rack and the charger are exposed from the flipping frame plate. And during the downward flipping process of the flipping frame plate, the angle between the flipping frame plate and the translation frame increases, causing the angular transmission structure to drive the movable plate to move within the storage rack. When the flipping frame plate completes the downward flipping, the plate groove of the movable plate just aligns with the storage cavity, and the user can take out the charging gun from the storage cavity for charging operations, reducing the usage steps of the device, facilitating the user's operation, and thus being conducive to the popularization and use of this device.

[0018] 3. In the ceiling-mounted charging pile and its usage method, when the flipping frame plate flips back in the reverse direction to reset, it will drive the reset of the movable plate. During the reset process of the movable plate, the movable plate will drive the second lead screw to reverse, and then drive the concave wheel to reverse through the second lead screw to retract the cable into the storage cavity, avoiding part of the cable from jamming the movable plate, thereby avoiding device failures and facilitating the continuous use of the device.

[0023] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more unless otherwise specifically defined.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 As shown, one of the purposes of this embodiment is to provide a ceiling charging pile, including a ceiling assembly 1 and a charging assembly 2 arranged in the ceiling assembly 1; The ceiling component 1 includes a ceiling suspension 11 fixed on the basement top plate and a translation frame 12 slidably connected to the ceiling suspension 11; The charging component 2 includes a flipping frame plate 21 rotatably connected to the inner wall of the translation frame 12. A storage rack 22 is slidably connected inside the flipping frame plate 21. A charger 23 for charging is provided inside the storage rack 22. Shielding bodies for shielding the charging gun of the charger 23 are provided on both sides of the storage rack 22. When the ceiling suspension 11 drives the translation frame 12 to slide until the charger 23 reaches above the front or rear end of the vehicle, under the action of the self-weight of the charging component 2, the flipping frame plate 21 flips downward from the side away from the vehicle, avoiding contact with the vehicle ceiling, so that the storage rack 22 moves downward along the flipping frame plate 21. As Figure 9 shown, during the process of the flipping frame plate 21 flipping downward and the storage rack 22 moving downward along the flipping frame plate 21 to release the charger 23, the angle between the flipping frame plate 21 and the translation frame 12 changes, and when the angle between the flipping frame plate 21 and the translation frame 12 becomes larger, it drives the shielding body to move and exposes the charging gun of the charger 23.

[0025] The above structure is disclosed as follows: As Figure 2 、 Figure 3 shown, openings for expansion bolts to pass through are provided at the four corners of the ceiling suspension 11. The ceiling suspension 11 is fixed on the basement top plate through expansion bolts. A translation frame 12 is horizontally slidably connected to the ceiling suspension 11. A motor is provided at one end of the ceiling suspension 11. The motor is connected to a first lead screw 111. The first lead screw 111 passes through the translation frame 12 and is threadedly connected to the translation frame 12. The motor controls the movement of the translation frame 12 through the provided first lead screw 111. A corner roller 112 is provided at the bottom of the other end of the ceiling suspension 11. The bottom surfaces of the translation frame 12, the flipping frame plate 21, and the storage rack 22 are all in contact with the corner roller 112. The ceiling suspension 11 is arranged on the basement top plate above the basement parking space. By driving the first lead screw 111 to rotate through the motor, the translation frame 12 threadedly connected to the first lead screw 111 is driven to horizontally slide along the ceiling suspension 11 towards the front or rear of the vehicle. When the translation frame 12 slides, it drives the charging component 2 to move synchronously until the bottom of the charging component 2 is suspended and not in contact with the corner roller 112. At this time, under the action of the self-weight of the charging component 2, the flipping frame plate 21 will flip downward from the side away from the vehicle. By moving the device to a position away from the vehicle and then flipping it downward, it can avoid problems such as vehicle damage and device failure caused by the device being stuck by the vehicle ceiling during flipping.

[0026] During the process of the flipping frame plate 21 flipping downward, the charger 23 needs to be taken out of the flipping frame plate 21 and close to the ground for the user to operate the charger 23. As Figure 3 、 Figure 4 、 Figure 5As shown, the flipping frame plate 21 is a "U"-shaped structural plate rotatably connected to the inner wall of the translation frame 12. The storage rack 22 is located inside the flipping frame plate 21. Sliding wheels 221 are provided on both sides of the storage rack 22 near one end of the motor. Displacement grooves 211 are correspondingly formed on the flipping frame plate 21. The sliding wheels 221 are located inside the displacement grooves 211. The storage rack 22 and the flipping frame plate 21 are slidably connected through the sliding wheels 221 and the displacement grooves 211. The storage rack 22 is integrally of a "mouth" shape. The charger 23 is located inside the central opening of the storage rack 22. The shielding body includes movable plates 222 located inside both ends of the storage rack 22. The movable plates 222 are inserted and matched with the inside of both ends of the storage rack 22. Storage cavities 225 for accommodating charging guns are formed at both sides of the storage rack 22 away from one end of the motor. The movable plates 222 pass through the storage cavities 225. The movable plates 222 are strip-shaped plates with plate grooves formed on the surfaces. The shape of the plate grooves matches the shape of the storage cavities 225. Angular transmission structures are provided at both sides of the storage rack 22 near one end of the motor. The angular transmission structures are in transmission connection with the movable plates 222. The angular transmission structures drive the movable plates 222 to move by using the change in the angle between the flipping frame plate 21 and the translation frame 12. During the downward flipping process of the flipping frame plate 21, under the self-weight of the storage rack 22 and the charger 23, the sliding wheels 221 of the storage rack 22 slide down to the bottom along the displacement grooves 211. At this time, the storage rack 22 and the charger 23 are exposed from the flipping frame plate 21. And during the downward flipping process of the flipping frame plate 21, the increase in the angle between the flipping frame plate 21 and the translation frame 12 causes the angular transmission structures to drive the movable plates 222 to move inside the storage rack 22. When the flipping frame plate 21 finishes downward flipping, the plate grooves of the movable plates 222 just align with the storage cavities 225, and the user can take out the charging gun from the storage cavities 225 for charging operations.

[0027] The above angular transmission structure is specifically disclosed as follows: As Figure 6 , Figure 7As shown, the angular transmission structure includes a hollow shaft 223, which is rotatably connected to the inner wall of the storage rack 22. One end of the movable plate 222 close to the hollow shaft 223 is connected with a sleeve, and one end of the hollow shaft 223 passes through the sleeve and is threadedly connected with the sleeve. A frame-side shaft 121 is provided on the inner wall of the translation frame 12, and the frame-side shaft 121 is inserted and matched with the flipping frame plate 21. The flipping frame plate 21 rotates around the frame-side shaft 121. An inner shaft 122 is rotatably connected to the inner wall of the flipping frame plate 21. One end of the inner shaft 122 is engaged with one end of the frame-side shaft 121, and the other end of the inner shaft 122 is connected with the hollow shaft 223. When the flipping frame plate 21 flips downward, the included angle between the flipping frame plate 21 and the translation frame 12 will change. The flipping frame plate 21 rotates around the frame-side shaft 121, and the frame-side shaft 121 is fixed on the translation frame 12 and does not rotate by itself. Therefore, when the flipping frame plate 21 flips downward, the inner shaft 122 engaged with the frame-side shaft 121 will rotate, and the rotation of the inner shaft 122 will drive the hollow shaft 223 to rotate. Then, the sleeve threadedly connected with the hollow shaft 223 drives the movable plate 222 to move along the inner wall of the storage rack 22. When the flipping frame plate 21 finishes flipping downward, the plate groove of the storage rack 22 just aligns with the storage cavity 225, and the user can take out the charging gun from the storage cavity 225 to charge the vehicle.

[0028] It should be noted that when the flipping frame plate 21 flips downward, there is also a movement process in which the storage rack 22 moves downward along the displacement groove 211. In this process, in order to ensure that the inner shaft 122 can drive the hollow shaft 223 to rotate continuously and avoid affecting the movement of the storage rack 22, the end of the inner shaft 122 away from the frame-side shaft 121 is inserted and matched with the hollow shaft 223. The surface of the inner shaft 122 is provided with a cross projection, and the inner shaft 122 is clamped and matched with the hollow shaft 223 through the provided cross projection. By setting the insertion and clamping cooperation methods, when the flipping frame plate 21 flips downward, a part of the inner shaft 122 is pulled out from the hollow shaft 223 to ensure that the storage rack 22 can move downward along the displacement groove 211, and the inner shaft 122 can continue to drive the rotation of the hollow shaft 223.

[0029] Under normal circumstances, after the user inserts the charging gun into the charging interface of the vehicle, they will leave the basement. It is not until the user needs to use the vehicle that they will come to the basement, pull out the charging gun and place it into the storage cavity 225, and then drive away from the basement parking space. At this time, the motor drives the first lead screw 111 to reverse, and the first lead screw 111 further drives the translation frame 12 connected to it by threads to slide horizontally along the ceiling suspension 11 to reset. During the reset process, the translation frame 12 will drive the flipping frame plate 21 past the corner roller 112. After the bottom of the flipping frame plate 21 contacts the corner roller 112, under the continuous pulling of the translation frame 12, the flipping frame plate 21 will reverse flip with the corner roller 112 as the inflection point, making the angle between the flipping frame plate 21 and the translation frame 12 smaller. Then, the angular transmission structure will naturally drive the movable plate 222 to reset, so that the non-plate groove area on the movable plate 222 aligns with the storage cavity 225 to seal and store the charging gun in the storage cavity 225. During this process, there will be a problem regarding the charging gun. Since the charging gun is connected to the charger 23 through a cable, and the user will pull out a certain length of the cable when using the charger for charging to facilitate aligning the charging gun with the vehicle charging port and inserting it. When the user places the charging gun into the storage cavity 225, part of the cable will be outside the storage cavity 225, or during the reverse flipping and resetting process of the flipping frame plate 21, part of the cable will fall outside the storage cavity 225. As a result, when the movable plate 222 resets, the cable will get stuck on the movable plate 222, causing damage to the cable or the movable plate 222.

[0030] To avoid the occurrence of the above situation, as Figure 8 shown, a second lead screw 224 is rotatably connected to the inner wall of the end of the storage rack 22 away from the motor. The movable plate 222 is correspondingly provided with a cross plate. The second lead screw 224 passes through the cross plate, and the second lead screw 224 is threadedly connected to the movable plate 222 through the provided cross plate. A reel body 226 is arranged in the storage cavity 225. The reel body 226 includes a pair of concave wheels. The cable of the charging gun passes between the two concave wheels and contacts the surface of the concave wheels. The concave wheels are rotatably connected to the inner wall of the storage cavity 225. One end of the second lead screw 224 meshes with the concave wheels. When the flipping frame plate 21 flips downward, it will drive the movable plate 222 to move. During the process of the plate groove of the movable plate 222 aligning with the storage cavity 225, the movable plate 222 will drive the second lead screw 224 connected to it by threads to rotate, and then drive the concave wheels through the second lead screw 224 to pull out the cable outward, so that after the plate groove aligns with the storage cavity 225, the user can take out the charging gun from the storage cavity 225; when the flipping frame plate 21 reversely flips and resets, it will drive the reset of the movable plate 222. During the reset process of the movable plate 222, the movable plate 222 will drive the second lead screw 224 to reverse, and then drive the concave wheels through the second lead screw 224 to reverse and retract the cable into the storage cavity 225, thereby avoiding the situation where part of the cable gets stuck on the movable plate 222.

[0031] In addition, after the flipping frame plate 21 completes the reverse flipping and resetting, in order to be able to pull the storage rack 22 and the charger 23 back to their original positions, as Figure 10 shown, a wire winding body 212 is also provided at one end of the flipping frame plate 21 close to the motor. The wire winding body 212 includes a reel rotatably connected to the inner wall of the flipping frame plate 21. Torsion springs are arranged on both sides of the reel. The reel is connected to the inner wall of the flipping frame plate 21 through the arranged torsion springs. A pulling rope is wound on the reel. One end of the pulling rope is connected to the surface of the storage rack 22. During the downward flipping process of the flipping frame plate 21, the gravity of the storage rack 22 and the charger 23 is greater than the elastic force of the torsion spring. The storage rack 22 can move downward along the displacement groove 211. When moving downward, the pulling rope drives the reel to rotate, so that the torsion spring is compressed. When the flipping frame plate 21 is reversely flipped and reset, the whole storage rack 22 changes from vertical to horizontal. The sliding friction force of the storage rack 22 is less than the elastic force of the torsion spring, so that under the action of the torsion spring, the reel reversely rotates and can drive the storage rack 22 and the charger 23 back to their original positions through the pulling rope, thus facilitating the storage of the device.

[0032] The second object of this embodiment is to further provide a method for using the above-mentioned ceiling charging pile, and the specific steps are as follows: S1. The motor drives the first lead screw 111 to rotate, and then drives the translation frame 12 threadedly connected to the first lead screw 111 to horizontally slide along the ceiling suspension 11 towards the head or tail of the vehicle. When the translation frame 12 slides, it drives the charging assembly 2 to move synchronously until the bottom of the charging assembly 2 is suspended and does not contact the corner roller 112. At this time, under the action of the self-weight of the charging assembly 2, the flipping frame plate 21 will flip downward from the side away from the vehicle; S2. When the flipping frame plate 21 flips downward, the inner shaft 122 meshing with the frame edge shaft 121 will rotate, and the rotation of the inner shaft 122 will drive the hollow shaft 223 to rotate. Then, the sleeve threadedly connected to the hollow shaft 223 drives the movable plate 222 to move along the inner wall of the storage rack 22. When the flipping frame plate 21 completes the downward flipping, the plate groove of the storage rack 22 just aligns with the storage cavity 225, and the user can take out the charging gun from the storage cavity 225 to charge the vehicle; S3. The motor drives the first lead screw 111 to reverse, and the first lead screw 111 then drives the translation frame 12 threadedly connected to it to horizontally slide and reset along the ceiling suspension 11. Under the continuous pulling of the translation frame 12, the flipping frame plate 21 will reversely flip with the corner roller 112 as the inflection point; S4. When the flipping frame plate 21 is reversely flipped and reset, it will drive the reset of the movable plate 222. During the reset process of the movable plate 222, the movable plate 222 will drive the second lead screw 224 to reverse, and then drive the cam to reverse through the second lead screw 224 to retract the cable into the storage cavity 225. Under the action of the torsion spring, the reel reversely rotates and can drive the storage rack 22 and the charger 23 back to their original positions through the pulling rope.
