Description

Technical Field

[0001] The present invention relates to the technical field of pure electric drive vehicle charging piles, and specifically to a high-reliability DC charging and discharging device. Background Art

[0002] As a DC charging and discharging device, an automotive charging pile directly outputs direct current and can charge the battery of a pure electric drive vehicle. It usually has a relatively large power (such as 30kW, 60kW, 120kW or even higher), is suitable for fast charging, and is commonly found in places such as highway service areas and public charging stations that require fast charging, providing a favorable energy guarantee for the long-distance driving of pure electric drive vehicles.

[0003] As can be seen from the above, existing automotive charging piles are commonly found in places such as highway service areas and public charging stations. When an automotive charging pile charges a pure electric drive vehicle in an outdoor environment, water is likely to accumulate at the vehicle charging port part in rainy weather, posing certain potential safety hazards to both the charging pile and the vehicle itself.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a high-reliability DC charging and discharging device is proposed. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high-reliability DC charging and discharging device, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A high-reliability DC charging and discharging device includes a charging pile main body and a charging head component. The two bottom sides of the charging pile main body are connected to the charging head component through wires. The charging head component includes a handle, a charging head, a first damping rotating shaft, a spring telescopic rod, a second damping rotating shaft, an elastic ring gasket, a slit, and an elastic rubber cylinder. The charging head is fixed at the end of the handle, and the outer wall of the handle is annularly distributed with the first damping rotating shaft. The outer wall of the first damping rotating shaft is connected to the spring telescopic rod, and the end of the spring telescopic rod is connected to the second damping rotating shaft. The outer wall of the second damping rotating shaft is connected to the elastic ring gasket, and a slit is annularly formed on the side surface of the elastic ring gasket. The outer wall of the charging head is sleeved with the elastic rubber cylinder.

[0007] Furthermore, one end of the elastic rubber cylinder is fixedly connected to the outer wall of the handle, and the other end of the elastic rubber cylinder is connected to the side surface of the elastic ring gasket.

[0008] Furthermore, the charging head component further includes a transmission airbag, and the transmission airbag is arranged inside the elastic ring gasket.

[0009] Further, the charging terminal assembly further includes a filling airbag, and the elastic ring pad is provided with a filling airbag on the inner surface of the slit.

[0010] Further, the filling airbag is communicated with the transmission airbag, and the transmission airbag is annularly embedded in the elastic ring pad.

[0011] Further, cleaning boxes are arranged on both sides of the charging pile main body, and sleeves are fixed on the upper part of the inner wall of the cleaning box.

[0012] Further, the handle and the charging head pass through the cleaning box, and the charging head is inserted into the sleeve.

[0013] Further, a cleaning component is rotatably connected to the outer side of the sleeve on the inner wall of the cleaning box. The cleaning component includes a first transmission disk and a cleaning brush, and the cleaning brush is arranged on the side surface of the first transmission disk.

[0014] Further, the cleaning brush is of an annular structure, and the surface of the cleaning brush is attached to the surface of the elastic ring pad.

[0015] Further, the cleaning component further includes a second transmission disk, a transmission belt and a driving motor. A second transmission disk is arranged above the first transmission disk, and the second transmission disk is in transmission connection with the first transmission disk through the transmission belt. The side surface of the second transmission disk is connected with the driving motor.

[0016] The present invention provides a high-reliability DC charging and discharging device, which has the following beneficial effects:

[0017] 1. For this high-reliability DC charging and discharging device, when the charging head is inserted into the vehicle charging port, the elastic ring pad is adapted to fit the vehicle surface, and based on the opening and closing angle of the cover plate at the vehicle charging part, the cover plate is wrapped inside the elastic rubber cylinder, or the slit on the surface of the elastic ring pad is used to well make the elastic ring pad transition from the cover plate surface to the vehicle surface when fitting, thereby protecting and shielding the vehicle charging port part, avoiding the accumulation of rainwater at the charging port part during charging in rainy weather, thereby protecting the DC charging and discharging device and the vehicle, and improving the reliability during charging in rainy weather.

[0018] 2. For this high-reliability DC charging and discharging device, when the elastic ring pad fits to the vehicle surface through elastic action, it is compressed by its own force, so that the transmission airbag inside the elastic ring pad is compressed, and the gas inside the transmission airbag is squeezed into the filling airbag, and the filling airbag inside the slit at the transition from the cover plate surface to the vehicle surface expands, thereby further filling the leak gap at the transition from the cover plate surface to the vehicle surface to enhance the waterproof effect of the vehicle charging port part.

[0019] 3. After the high-reliability DC charging and discharging device finishes charging, manually unplug the charging head and place it inside the cleaning box. At this time, the charging head is inserted into the sleeve. Then, drive the second transmission disk through the drive motor and make the first transmission disk drive the cleaning brush to rotate through the transmission belt. The cleaning brush rotates while sticking to the surface of the elastic ring gasket, thereby cleaning the surface of the elastic ring gasket, so as to prevent dirt from adhering to the vehicle surface due to dust and impurities adhering to its surface the next time the elastic ring gasket is used.

[0027] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0028] As Figures 1-6As shown in the figure, the present invention provides a technical solution: a highly reliable DC charging and discharging device, including a charging pile host 1 and a charging head component 3. The bottom sides of both sides of the charging pile host 1 are connected to the charging head component 3 through wires 2. The charging head component 3 includes a grip 301, a charging head 302, a first damping rotating shaft 303, a spring telescopic rod 304, a second damping rotating shaft 305, an elastic ring gasket 306, a slit 307, and an elastic rubber cylinder 308. The end of the grip 301 is fixed with the charging head 302, and the outer wall of the grip 301 is annularly distributed with the first damping rotating shaft 303. The outer wall of the first damping rotating shaft 303 is connected to the spring telescopic rod 304, and the end of the spring telescopic rod 304 is connected to the second damping rotating shaft 305. The outer wall of the second damping rotating shaft 305 is connected to the elastic ring gasket 306, and a slit 307 is annularly formed on the side surface of the elastic ring gasket 306. The outer wall of the charging head 302 is sleeved with an elastic rubber cylinder 308. One end of the elastic rubber cylinder 308 is fixedly connected to the outer wall of the grip 301, and the other end of the elastic rubber cylinder 308 is connected to the side surface of the elastic ring gasket 306;

[0029] The specific operation is as follows. When inserting the charging head 302 into the vehicle charging port, the elastic ring gasket 306 adheres to the vehicle surface around the charging port. At this time, under the elastic action of the spring telescopic rod 304, the elastic ring gasket 306 is adapted to closely adhere to the vehicle surface. At this time, based on the opening and closing angle of the vehicle charging port cover, if the opening and closing angle is 180 degrees, a part of the side surface of the elastic ring gasket 306 adheres to the cover surface, and the slit 307 is used to well make the elastic ring gasket 306 transition from the cover surface to the vehicle surface, avoiding leakage when the elastic ring gasket 306 fits due to the cover surface and the vehicle surface not being on the same surface. When the opening and closing angle of the cover is less than 90 degrees, the cover is located inside the elastic rubber cylinder 308. The elastic function of the elastic rubber cylinder 308 itself and the fitting action of the elastic ring gasket 306 with the vehicle surface are used to prevent the vehicle charging port from being exposed. Moreover, the spring telescopic rod 304 can expand when fitting to the vehicle surface through the first damping rotating shaft 303. At this time, the elastic ring gasket 306 can also expand its inner diameter by its own elastic action, thereby fully wrapping the charging port part;

[0030] Based on the above description, the present invention uses the action of inserting the charging head 302 into the vehicle charging port to adapt and fit the elastic ring gasket 306 to the vehicle surface, and based on the opening and closing angle of the cover of the vehicle charging part, wraps the cover inside the elastic rubber cylinder 308 or uses the slit 307 on the surface of the elastic ring gasket 306 to well make the elastic ring gasket 306 transition from the cover surface to the vehicle surface when fitting, thereby protecting and shielding the vehicle charging port part, avoiding rainwater accumulation at the charging port part during charging in rainy weather, thereby protecting the DC charging and discharging device and the vehicle, and improving the reliability during charging in rainy weather.

[0031] As Figures 1-6As shown, the charging head assembly 3 further includes a transmission airbag 309. The transmission airbag 309 is disposed inside the elastic ring gasket 306. The charging head assembly 3 further includes a filling airbag 310. The filling airbag 310 is disposed on the inner surface of the elastic ring gasket 306 at the slit 307. The filling airbag 310 is communicated with the transmission airbag 309, and the transmission airbag 309 is annularly embedded inside the elastic ring gasket 306;

[0032] The specific operation is as follows. When the elastic ring gasket 306 fits onto the vehicle surface through elastic action, it is compressed by the force on itself, causing the transmission airbag 309 inside the elastic ring gasket 306 to be compressed. As a result, the gas inside the transmission airbag 309 is squeezed into the filling airbag 310, and the filling airbag 310 inside the slit 307 at the transition from the cover plate surface to the vehicle surface expands, thereby further filling the leak gap at the transition from the cover plate surface to the vehicle surface to enhance the waterproof effect of the vehicle charging port part.

[0033] As Figures 1-3 As shown, cleaning boxes 4 are provided on both sides of the charging pile main body 1, and a sleeve 5 is fixed to the upper part of the inner wall of the cleaning box 4. The handle 301 and the charging head 302 pass through the inside of the cleaning box 4, and the charging head 302 is inserted into the sleeve 5. A cleaning component 6 is rotatably connected to the outer side of the sleeve 5 on the inner wall of the cleaning box 4. The cleaning component 6 includes a first transmission disk 601 and a cleaning brush 602. The cleaning brush 602 is disposed on the side surface of the first transmission disk 601. The cleaning brush 602 has an annular structure, and the surface of the cleaning brush 602 is in contact with the surface of the elastic ring gasket 306. The cleaning component 6 further includes a second transmission disk 603, a transmission belt 604, and a driving motor 605. A second transmission disk 603 is provided above the first transmission disk 601, and the second transmission disk 603 is drivingly connected to the first transmission disk 601 through the transmission belt 604. The side surface of the second transmission disk 603 is connected to the driving motor 605;

[0034] The specific operation is as follows. After charging is completed, the charging head 302 is manually unplugged and placed inside the cleaning box 4. At this time, the charging head 302 is inserted into the sleeve 5. Then, the driving motor 605 drives the second transmission disk 603, and through the transmission belt 604, the first transmission disk 601 drives the cleaning brush 602 to rotate. The cleaning brush 602 rotates while being in contact with the surface of the elastic ring gasket 306, thereby cleaning the surface of the elastic ring gasket 306. Additionally, a flushing nozzle can be configured to enhance the cleaning effect. The charging head 302 inserted into the sleeve 5 can prevent the flushing water from entering the inside of the charging head 302, so that when the elastic ring gasket 306 is used next time, it can prevent dirt from adhering to the vehicle surface due to dust and impurities adhering to its surface.

[0035] In summary, for the highly reliable DC charging and discharging device, during use, when the charging head 302 is first inserted into the vehicle charging port, the elastic ring gasket 306 adheres to the vehicle surface around the charging port. At this time, under the elastic action of the spring telescopic rod 304, the elastic ring gasket 306 is adapted to closely adhere to the vehicle surface. By utilizing the elastic function of the elastic rubber cylinder 308 itself and the fitting action between the elastic ring gasket 306 and the vehicle surface, the vehicle charging port is prevented from being exposed. Moreover, the spring telescopic rod 304 can expand when it fits to the vehicle surface through the first damping rotating shaft 303. At this time, the elastic ring gasket 306 can also expand its inner diameter by using its own elastic action, thereby fully wrapping the charging port part to prevent rainwater from intruding.

[0036] When the elastic ring gasket 306 adheres to the vehicle surface through elastic action, it is compressed by the force on itself, causing the transmission airbag 309 inside the elastic ring gasket 306 to be compressed. The gas inside the transmission airbag 309 is squeezed into the filling airbag 310, and the filling airbag 310 inside the slit 307 at the transition from the cover plate surface to the vehicle surface expands, thereby further filling the leakage gap at the transition from the cover plate surface to the vehicle surface to enhance the waterproof effect on the vehicle charging port part.

[0037] Finally, after charging is completed, the charging head 302 is manually unplugged and placed inside the cleaning box 4. At this time, the charging head 302 is inserted into the sleeve 5. Then, the driving motor 605 drives the second transmission disk 603, and through the transmission belt 604, the first transmission disk 601 drives the cleaning brush 602 to rotate. The cleaning brush 602 rotates while adhering to the surface of the elastic ring gasket 306, thereby cleaning the surface of the elastic ring gasket 306. An additional flushing nozzle can be configured to enhance the cleaning effect. Inserting the charging head 302 into the sleeve 5 can prevent the flushing water from entering the inside of the charging head 302, so that when the elastic ring gasket 306 is used next time, it can prevent dirt from adhering to the vehicle surface due to dust and impurities adhering to its surface.
