DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The utility model provides a license plate bracket for a new energy vehicle capable of automatically cleaning the license plate, which includes a bracket body 1 fixedly assembled on the new energy vehicle body. As Figure 1 shown, a license plate 2 is fixedly assembled on the bracket body 1 through four fixing bolts 3. A slider 6 is in limit sliding fit on the bracket body 1, and a cleaning brush 10 is assembled on the slider 6. The cleaning part of the cleaning brush 10 is made of soft bristles and is in contact sliding fit with the surface of the license plate 2 where the license plate characters are displayed for cleaning. The length of the cleaning brush 10 is greater than the width of the license plate 2 to ensure that the cleaning part of the cleaning brush 10 is always in contact with the license plate 2 when cleaning the license plate 2.

[0025] A first power mechanism is assembled on the bracket body 1. The output end of the first power mechanism is in transmission connection with the slider 6 for pushing the slider 6 to reciprocate along the length direction of the license plate 2. The first power mechanism includes a motor 4. The motor 4 is bolted to the bracket body 1 and an output shaft is coaxially fixedly connected with a threaded rod 5 along the length direction of the license plate 2. The end of the threaded rod 5 far from the motor 4 is rotatably connected to the bracket body 1. The threaded rod 5, as the output end of the first power mechanism, passes through the slider 6 and is in threaded connection with the slider 6.

[0026] As Figure 2 and Figure 4 shown, the cleaning brush 10 is arranged along the width direction of the license plate 2. The cleaning brush 10 is fixedly connected with a sliding shaft 7. The sliding shaft 7 passes through the slider 6 along the width direction of the license plate 2 and is in sliding fit with the slider 6. A second power mechanism is assembled on the bracket body 1. The output end of the second power mechanism is in transmission connection with the cleaning brush 10 for driving the cleaning brush 10 to reciprocate along the width direction of the license plate 2. The second power mechanism includes a spring 8, a vertical shaft 13 and a guiding rack 15. Among them, the guiding rack 15 is arranged along the length direction of the license plate 2. The bracket body 1 is cut out with a first chute 14 along the length direction of the license plate 2. The teeth of the guiding rack 15 are located in the first chute 14 and face the license plate 2 along the width direction of the license plate 2. The vertical shaft 13, as the second output end of the second power mechanism, is fixedly connected with the cleaning brush 10. The vertical shaft 13 passes through the first chute 14 and is in sliding abutting fit with the teeth of the guiding rack 15 for pushing the vertical shaft 13 to approach the license plate 2 along the width direction of the license plate 2.

[0027] All the teeth of the guiding rack 15 are arranged in a wavy transmission structure to ensure that the vertical shaft 13 can be in sliding abutting fit with the teeth of the guiding rack 15. A limiting block is welded and fixed at the end of the vertical shaft 13 far from the cleaning brush 10. The limiting block covers the notch of the first chute 14 and is in limit sliding abutting fit with the bracket body 1 to ensure that the slider 6 will not rotate with the threaded rod 5 during the sliding process.

[0028] The spring 8 as the first output end of the second power mechanism is sleeved on the sliding shaft 7. The end of the spring 8 close to the cleaning brush 10 is fixedly connected to the slider 6, and the end of the spring 8 away from the cleaning brush 10 is fixedly connected to the sliding shaft 7, which is used to drive the cleaning brush 10 to drive the vertical shaft 13 away from the license plate 2 along the width direction of the license plate 2.

[0029] The end of the sliding shaft 7 away from the cleaning brush 10 is coaxially fixedly connected to a limit plate to prevent the sliding shaft 7 from sliding off the sliding block 6 .

[0030] A fixing rod 9 is welded on the slider 6, and the fixing rod 9 is arranged along the width direction of the license plate 2. A cleaning brush 10 is located between the fixing rod 9 and the bracket body 1. Figure 3 and Figure 4 As shown, a plurality of rotating shafts are welded on the fixed rod 9, and each rotating shaft is arranged along the length direction of the license plate 2. Each rotating shaft is rotatably connected to a rotating rod 16, and each rotating rod 16 is fixedly equipped with a spray head 19, each spray head 19 faces the surface of the license plate 2 displaying the license plate text and is connected to a water pipe 20, and all water pipes 20 are connected to a water pump in the vehicle body for washing the license plate 2.

[0031] The cleaning brush 10 is connected to each rotating rod 16 through a transmission assembly. When the cleaning brush 10 moves along the width direction of the license plate 2, the transmission assembly pushes the rotating rod 16 to rotate along the rotating shaft. The transmission assembly includes a transmission rod 18, which is arranged along the length direction of the license plate 2 and is fixedly connected to the cleaning brush 10. A second slide groove 17 is cut on the rotating rod 16, and the transmission rod 18 is inserted into the second slide groove 17 and cooperates with the second slide groove 17 in both limited sliding and transmission, so as to push the rotating rod 16 to rotate along the rotating shaft.

[0032] like Figure 2 As shown, a micro air pump 11 is fixed by screws on the slider 6, and the air outlet of the micro air pump 11 is fixedly connected to an air pipe 12. The air pipe 12 is away from the pipe mouth of the micro air pump 11 and faces the surface of the license plate 2 displaying the license plate text, and is used to blow air toward the license plate 2, thereby blowing dust, debris or water droplets away from the license plate 2, improving the cleanliness while accelerating the drying of the license plate 2 to prevent water droplets from absorbing dust.

[0033] Working principle: When in use, the motor 4 and the water pump in the vehicle body are started, the output shaft of the motor 4 drives the threaded rod 5 to rotate, and the threaded rod 5 pushes the slider 6 to move along the length direction of the license plate 2 toward the direction close to the motor 4. In this process, the slider 6 drives the fixed rod 9 and the cleaning brush 10 to move synchronously.

[0034] During the movement of the fixed rod 9, the rotating rod 16 is driven to move synchronously. The rotating rod 16 drives the nozzle 19 to move synchronously. The nozzle 19 sprays the water flowing into the water pipe 20 onto the license plate 2 to wash the license plate 2. During the movement of the cleaning brush 10, the license plate 2 that has been sprayed with water is cleaned along the length direction. At the same time, the cleaning brush 10 drives the vertical shaft 13 to move synchronously. The vertical shaft 13 slides in the first chute 14. When the vertical shaft 13 contacts the teeth of the guiding rack 15, the teeth of the guiding rack 15 push the vertical shaft 13 to approach the license plate 2 along the width direction of the license plate 2. At this time, the vertical shaft 13 drives the cleaning brush 10 to move synchronously. The cleaning brush 10 drives the sliding shaft 7 to move synchronously, and the sliding shaft 7 stretches the spring 8. When the vertical shaft 13 slides over the tooth crest of the teeth of the guiding rack 15, under the pulling force of the spring 8, the vertical shaft 13 moves away from the license plate 2 along the width direction of the license plate 2, thus completing the cleaning in the width direction.

[0035] When the cleaning brush 10 cleans the license plate 2 along the width direction of the license plate 2, the cleaning brush 10 drives the transmission rod 18 to push the rotating rod 16 to rotate around the axis where the rotating rod 16 is located. The rotating rod 16 drives the nozzle 19 to rotate synchronously, so that the water sprayed onto the license plate 2 is evenly sprayed.

[0036] After the cleaning is completed when the cleaning brush 10 moves to the end of the license plate 2, then the output shaft of the motor 4 rotates in reverse to stop the water pump in the vehicle body, and the nozzle 19 no longer sprays water. The output shaft of the motor 4 drives the threaded rod 5 to push the slider 6 to slide along the length direction of the license plate 2 away from the motor 4 for resetting. At this time, the cleaning brush 10 is reset, and at the same time, the micro air pump 11 is turned on. During the resetting process, the air sprayed by the micro air pump 11 blows onto the license plate 2 through the air pipe 12 to dry the water droplets on the license plate 2.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
