Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments.
In the description of the present invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present invention and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention.
Embodiment one:
referring to fig. 1-2, a self-cleaning vehicle-mounted reversing camera comprises a shell 1, wherein a camera body 2 is installed in the shell 1, a transparent glass plate 3 is rotatably connected in the shell 1, a baffle 4 is fixedly connected at the inner bottom of the shell 1, a sliding groove 41 is formed in the side wall of the baffle 4, and a cleaning brush 7 is slidably connected in the sliding groove 41. The cleaning brush 7 is elastically connected to the inner bottom of the chute 41 through a spring 8, and a driving device for driving the transparent glass plate 3 to rotate is installed in the housing 1.
The driving device comprises an electromagnet 5 embedded on the inner wall of the shell 1, an iron sheet 6 is embedded on the transparent glass plate 3, a power generation sheet 9 is arranged at the inner top of the sliding groove 41, and the cleaning brush 7 is composed of two parts, wherein the upper part is a hard plastic shell, the lower part is made of soft materials such as sponge, so that the power generation sheet 9 can be driven by pushing when the cleaning brush 7 moves up and down, and meanwhile, the transparent glass plate 3 can be cleaned. The power generation sheet 9 is made of piezoelectric ceramic material, a storage battery electrically connected with the power generation sheet 9 is arranged in the shell 1, and the storage battery is electrically connected with each electromagnet 5 through a control circuit. Specifically, the control circuit adopts the CD4017, and the electric energy that this circuit can make the battery release makes each electro-magnet 5 switch on in proper order, and the installation mode and the connected mode of circuit all belong to the mature technique in current electricity field, therefore do not make elaboration.
The control circuit sequentially energizes the electromagnets 5 to generate magnetism, and then attracts the iron sheets 6 to be sequentially attached to the electromagnets 5, so that the transparent glass plate 3 rotates unidirectionally, and thus the cleaning brush 7 sliding up and down can perform relative movement, and the cleaning effect of the cleaning brush 7 is further improved. In addition, the electric energy of each electromagnet 5 and the kinetic energy of the up-and-down movement of the cleaning brush 7 are generated by the vibration kinetic energy generated by the automobile, and no additional electric energy is consumed.
In the use process of the device, the vibration of each part of tail gas can be caused due to the pulse characteristic of tail gas discharge when the automobile runs, and the vibration is transmitted into the shell 1 through the automobile body, especially when the automobile runs in a reverse or turns around at a low speed, the vibration is more obvious. This causes the cleaning brush 7 to slide up and down in the chute 41 by the action of the spring 8, and the lower part region of the transparent glass plate 3 can be cleaned.
Meanwhile, the cleaning brush 7 continuously pushes the power generation piece 9 when sliding up and down, so that the power generation piece 9 is caused to continuously vibrate, the power generation piece 9 made of piezoelectric ceramic material can convert mechanical energy generated by vibration into electric energy and store the electric energy in the storage battery, the storage battery can enable each electromagnet 5 to be sequentially electrified through the control circuit, each electromagnet 5 is electrified, the iron piece 6 is attracted to be attached to the electromagnet, and referring to fig. 2, when each electromagnet 5 is sequentially electrified, the iron piece 6 is attracted by magnetic force to drive the transparent glass plate 3 to rotate in a unidirectional circulation mode, and therefore the cleaning brush 7 continuously slides up and down at the lower side part of the shell 1 can clean the exposed surface of the whole transparent glass plate 3, the transparent glass plate 3 can be kept in a clean state, so that dust is prevented from polluting an observation area of the camera body 2, the image definition in reversing or turning around is improved, and dangerous situations are prevented.
Embodiment two:
