Examples
Referring to fig. 1, the utility model discloses a wireless charging system prevents foreign matter device for the protection of wireless charging launching pad, it includes two bases 1, two linear guide 2, movable plate 3, cleans piece 4, spool 5, protecting band 6, wind spring dish 7 and power device 8.
Two bases 1 are respectively installed in the both sides of wireless transmission dish 9 that charges, and the one end of two bases 1 is equipped with first support 11, and the other end of two bases 1 is equipped with second support 12. The two linear guide rails 2 are respectively arranged on the two bases 1. The moving plate 3 is located above the wireless charging emission disc 9, and is strip-shaped, and two ends of the moving plate are respectively fixed on the sliding tables 21 of the two linear guide rails 2. The cleaning piece 4 is fixed below the moving plate 3, and the cleaning end thereof is abutted on the wireless charging launching pad 9, in this embodiment, the cleaning end thereof is a brush or a rubber strip. The reel 5 is rotatably mounted on the first bracket 11, and one end of the protective belt 6 is wound on the reel 5, and the other end is connected with the moving plate 3. The coil spring disk 7 is fixedly installed on the second support 12, in this embodiment, the telescopic end of the coil spring disk 7 is a steel ruler, so the number of the coil spring disks is two, and the coil spring disks are installed on the two second supports respectively to avoid the upper side of the wireless charging transmitting disk. The telescopic ends of the two coil spring disks 7 are connected with the moving plate 3. In this embodiment, the coil spring disks 7 are of the prior art.
The power device 8 is used for realizing the winding and the winding state keeping of the reel 5. Specifically, it includes a reduction motor 81, a brake 82, and a position sensor 83. The speed reducing motor 81 is used for driving the winding shaft 5 to wind, the brake 82 is used for braking the winding shaft 5, and at least one position sensor 83 is arranged at the tail end of a certain linear guide rail 2 and used for providing instructions for stopping the speed reducing motor 81 and starting the brake 82. In this embodiment, the position sensors 83 are two travel switches, and are distributed at the ends of the two linear guides 2 (i.e., the ends near the reel 5), so as to prevent a failure caused by a failure of one of the travel switches.
The working principle is as follows:
when a vehicle is charged, the speed reducing motor 81 executes a winding action under the control of the control system, at the moment, the protective belt 6 is wound and folded, the wireless charging transmitting disc 9 is gradually exposed, the protective belt 6 drives the moving plate 3 to slide in the process of winding and folding, and the cleaning piece 4 cleans the wireless charging transmitting disc in the process; when the moving plate 3 slides to the tail end of the linear guide rail 2, the position sensor 83 is triggered, then the speed reducing motor 81 stops running, the brake 82 brakes in a contracting mode, and the automobile starts to charge; after charging, the brake 82 is released, and the retractable end of the coil spring disk 7 retracts, so that the protective belt 6 is driven to unfold, and the work is finished.
In this embodiment, the width of the guard band 6 is greater than the distance between the two bases 1, so that the two bases 1 and the wireless charging transmitting disk 9 are covered under the guard band 6 in the unfolded state to form an environment approaching to a closed state (only a small gap exists between the guard band 6 and the upper portion of the linear guide 2), thereby reducing the probability of entering of foreign matters.
