Description

Rainproof wireless charging device for electric bicycle

Technical Field

The utility model relates to a wireless charging device of rainproof type electric bicycle.

Background

With the development of mobile wireless charging, experiments on mobile wireless charging have been started on automobiles, and experiments on mobile wireless charging on a public transportation system have been applied in korea. Although the cost is higher and the energy utilization rate is lower at present, the battery pack has the advantages of convenient use, strong cruising ability (theoretically, wireless cruising) and high safety, and has a certain commercial prospect.

Along with the concern of market to the short distance trip, within 5 kilometers, electric bicycle has and uses conveniently, and the speed advantage is obvious, stops to get advantages such as convenient, and electric bicycle's continuation of the journey mileage, application range have been restricted greatly to electric bicycle's traditional power supply mode, if combine together portable wireless charging and electric bicycle, the duration of the reinforcing electric bicycle that can be great. Especially, the device is used in industrial areas or large factories, and can meet the requirement of short-distance and frequent trips of personnel. Especially, when going out in rainy day, need to guarantee that wireless charging device has certain waterproof ability.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects of the prior art, providing a wireless charging device of a rainproof type electric bicycle.

A rainproof wireless charging device for an electric bicycle comprises a receiving box, wherein the receiving box is positioned at the bottom of the electric bicycle and comprises a box body and a box cover, a receiving coil is arranged inside the box body and is matched with a pre-buried transmitting coil below the ground, a first annular groove is formed in the upper surface of the box body, a second annular groove is formed in the side wall of the box body, a first sealing ring is embedded in the first annular groove, a second sealing ring is embedded in the second annular groove, a plurality of gaps are formed in the periphery of the box body, fasteners are arranged in the gaps, each fastener comprises an upper retaining ring, a connecting post, a spring and a lower retaining ring which are sequentially connected, the diameter of the connecting post is matched with the width of the gap, the diameters of the upper retaining ring and the lower retaining ring are larger than that of the connecting post, and when the box body is connected with the box cover through the fasteners, the lower surface of the upper retaining ring abuts against the upper surface of the box cover, the upper surface of the lower retaining ring abuts against the lower surface of the box body, and the second sealing ring is located at the opening of the notch.

Preferably, the receiving coil can move in parallel along the array direction of the transmitting coil, and the receiving coil covers a plurality of transmitting coils at any time of moving.

Preferably, the first sealing ring is made of polyurethane.

Preferably, the second sealing ring is made of polyurethane.

Preferably, the number of fasteners is four.

Has the advantages that:

1. through the cooperation of first sealing washer and second sealing washer, can the whole sealing capacity who receives the box of effectual promotion, guarantee in the rainy day, the rainwater can not be immersed the inside of receiving the box by gap department to cause the damage of internal coil.

2. Through the fastener with box body and lid equipment mutually, under the effect of spring, the lid is tightly pasted all the time on the box body, guarantees not hard up, simultaneously because the second sealing washer has just in time blocked the exit of breach, so, in use, the fastener can not the roll-off to guarantee whole device's stability and security.
