Abstract
Description
Technical Field
[0001] This utility model relates to the field of charging pile technology, and more specifically, to a charging pile with noise reduction function. Background Technology
[0002] Charging stations are essential replenishment facilities for electric vehicles, possessing multiple functions and a wide range of applications. They can be classified in various ways based on installation conditions, target users, location, and charging type.
[0003] When using a typical charging station, the user first unplugs the charging gun from the side of the charging station and inserts it into the charging port of the new energy vehicle. Then, by scanning the QR code on the charging station's screen, the vehicle can be charged. The charging station then begins operation. Because charging stations generate heat during use, a cooling system dissipates this heat. This cooling system vibrates and generates noise when it starts. Traditionally, to reduce noise, the cooling system is placed on top of a rubber pad.
[0004] However, when the rubber pad is in use, it makes it difficult for the heat at the bottom of the heat dissipation mechanism to dissipate, which increases the operating load of the heat dissipation mechanism. In addition, the rubber pad is in direct contact with the heat dissipation mechanism. When the rubber pad is exposed to a lot of heat, it will soften, resulting in a poor noise reduction effect. Therefore, it needs to be modified and optimized. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] See also Figures 1 to 6 This utility model provides a charging pile with noise reduction function, including a charging pile body 2. A second motor 24 for heat dissipation is installed inside the charging pile body 2. Two shock-absorbing pads 15 are fixedly installed on the bottom inner side of the charging pile body 2. A fixing block 16 is fixedly installed above each of the two shock-absorbing pads 15. A first damper 17 is fixedly installed between the two fixing blocks 16. A baffle 18 is fixedly sleeved on the outer surface of the first damper 17. First springs 19 are respectively sleeved on the first damper 17 on both sides of the baffle 18. One end of each first spring 19 is connected to the baffle. 18 is connected, and the other end of the first spring 19 is connected to a slider 20 that is movably sleeved on the first damper 17. A hinge block 21 is fixedly connected above the slider 20. A connecting rod 22 is hinged to the side of the hinge block 21. A top plate 23 is hinged to the end of the connecting rod 22 away from the hinge block 21. The top plate 23 is used to support the second motor 24. A second damper 29 is fixedly installed above the fixed block 16. The bottom of the second damper 29 is connected to the bottom of the top plate 23. A second spring 30 sleeved on the second damper 29 is connected between the bottom of the top plate 23 and the fixed block 16.
[0028] When a user needs to use the charging station, the device starts operating after the user scans the QR code. The second motor 24 then starts running, generating vibrations. These vibrations cause the top plate 23 to move up and down, which in turn moves one end of the connecting rod 22, causing the hinge block 21 to move left and right. This movement of the hinge block 21 then moves the slider 20 left and right. The vibrations generated by the second motor 24 are reduced by the cooperation of the first spring 19 and the first damper 17, thus reducing noise. Simultaneously, the movement of the top plate 23, through the action of the second damper 17, also reduces noise. The damper 29 and the second spring 30 work together to reduce the vibration generated by the second motor 24. The vibration is further reduced by the shock-absorbing pad 15, thereby reducing noise. Compared with traditional devices, this device reduces the vibration generated by the second motor 24 through the first spring 19, the first damper 17, the second damper 29 and the second spring 30. Compared with traditional devices, which reduce vibration and noise by using rubber pads, this device does not affect the heat dissipation of the second motor 24 and can further reduce the vibration generated by the second motor 24. By reducing vibration, noise is reduced, and the effect of the rubber pad softening due to heat and deteriorating noise reduction is avoided, thereby improving the noise reduction efficiency and the working efficiency of the device.
[0029] In some embodiments, a rotating rod 25 is connected to the end of the drive shaft of the second motor 24, and a fan blade 26 is installed at the end of the rotating rod 25 away from the second motor 24. By starting the second motor 24, the rotating rod 25 is driven to rotate, and when the rotating rod 25 rotates, it drives the fan blade 26 to rotate, thereby dissipating the heat inside the charging pile.
[0030] Specifically, the second motor 24 has a drive shaft and a rotating rod 25 at both ends.
[0031] In some embodiments, a heat dissipation hole 27 is provided on one side of the charging pile body 2, and the heat dissipation hole 27 is arranged opposite to the fan blade 26. A sound-insulating heat dissipation plate 28 is fixedly installed on the side inside the heat dissipation hole 27. The design of the heat dissipation hole 27 facilitates the dissipation of heat inside the charging pile, and the design of the sound-insulating heat dissipation plate 28 can block the sound generated inside the charging pile from escaping, thereby improving the user experience.
[0032] In other embodiments, heat dissipation holes 27 are provided on both sides of the charging pile body 2, and a sound-insulating heat dissipation plate 28 is fixedly installed on the side inside the heat dissipation hole 27.
[0033] Furthermore, a control display screen 3 is fixedly installed on one side wall of the charging pile body 2, and the control display screen 3 is electrically connected to the second motor 24. The design of the control display screen 3 facilitates users to scan codes and also allows them to know the operating status of the charging pile.
[0034] Furthermore, the charging pile body 2 has two grooves 6 on one side wall where the control display screen 3 is installed. The first motor 7 is fixedly installed in one groove 6. A connecting frame 8 is fixedly installed at one end of the drive shaft of the first motor 7. A threaded rod 9 is fixedly installed at one end of the connecting frame 8. A threaded block 10 is threadedly sleeved on the outer surface of the threaded rod 9. A slide rod 12 parallel to the threaded rod is fixedly installed in the other groove 6. Another threaded block 10 is movably sleeved on the outer surface of the slide rod 12. A roller 11 is connected between the two threaded blocks 10. A lint-resistant cloth is wrapped around the outer surface of the roller 11. The lint-resistant cloth slides in contact with the outer surface of the control display screen 3.
[0035] Specifically, the two adjacent grooves 6 have narrow through holes 13 on their sidewalls, and the roller 11 passes through the through holes 13, so that both ends of the roller 11 extend into the inner side of the two grooves 6 and connect with the threaded block 10. The outer surface of the roller 11 is wrapped with lint, so that the water stains on the surface of the control display screen 3 can be wiped away by the lint.
[0036] The charging pile with noise reduction function also includes a base frame 1, and the charging pile body 2 is fixedly installed on the top of the base frame 1. A button 31 is installed on one side wall of the charging pile body 2, and the button 31 is electrically connected to the first motor 7.
[0037] When the user uses the device, pressing button 31 will start the first motor 7. When the first motor 7 starts, it will drive the connecting frame 8 to rotate. When the connecting frame 8 rotates, it will drive the threaded rod 9 to rotate. When the threaded rod 9 rotates, since the threaded block 10 and the threaded rod 9 are connected by threads, and the rotation of the threaded block 10 is restricted by the slide rod 12, the rotation of the threaded rod 9 will drive the threaded block 10 to move. When the threaded block 10 moves, it will drive the roller 11 to move, thereby driving the lint wiper cloth to wipe the water stains on the surface of the control display screen 3.
[0038] By pressing button 31, the first motor 7 starts, thereby driving the connecting frame 8 and the threaded rod 9. As the threaded rod 9 rotates, it drives the roller 11 to move, which in turn drives the lint wiper to wipe the water stains on the surface of the control display screen 3. Compared with the traditional device, this device uses the movement of the roller 11 to drive the movement of the lint wiper. Compared with the traditional device, it achieves the cleaning of water stains by heating the surface of the control display screen 3. This device can avoid the surface of the control display screen 3 from heating up again, which would affect the operation of the control display screen 3. At the same time, it can also reduce the operating load of the control display screen 3. Heating the surface of the control display screen 3 will cause water droplets to dry and leave water stains. This device can wipe the water stains on the surface of the control display screen 3, thereby improving the efficiency of the device.
[0039] In other embodiments, the first motor 7 may also be electrically connected to the control display screen 3, and the user can control the first motor 7 to start through the control display screen 3.
[0040] The charging pile body 2 has connecting wires 4 fixedly installed on both its left and right sides. A plug 5 is fixedly installed at one end of each connecting wire 4, and one end of the plug 5 extends into the interior of the charging pile body 2 and is movably connected to it. Through the design of the connecting wires 4 and the plug 5, electrical energy inside the device can be transferred to the battery of the new energy vehicle.
[0041] A rear cover 14 is movably installed on one side of the charging pile body 2, and the rear cover 14 is located on the side of the shock-absorbing pad 15. The design of the rear cover 14 protects the operation of the second motor 24 and also protects the interior of the charging pile body 2.
