However, the electric vehicle needs to be charged by a charging system, and currently, high-current rapid charging of the electric vehicle can be performed by a pantograph charging system using a pantograph. The charging process of the pantograph charging system for the electric automobile is briefly described as follows: when the electric automobile enters the charging station, the pantograph rises through wireless WIFI communication, and a charging frame polar plate/charging cable of the charging device is contacted with the pantograph polar plate extending out of the electric automobile to charge the electric automobile. In this charging system, a pantograph is an indispensable component.
The pantograph in the prior art can be divided into a single-arm type pantograph, a double-arm type pantograph (diamond-shaped pantograph), a vertical type pantograph and the like, and the vast majority of the current pantographs are single-arm type pantographs. The single-arm bow can be divided into a connecting rod type, a vertical lifting type and a swinging type according to the lifting mechanism, and the single-arm bow is provided with a lifting state for being connected with the charging frame pole plate/charging cable and a falling state for being connected with the charging frame pole plate/charging cable and separated from the charging frame pole plate/charging cable and being tightly attached to a vehicle. The connecting rod type pantograph disclosed in Chinese patent publication No. CN105291849A, wherein the pantograph body comprises an upper supporting rod and a lower supporting rod which are in foldable arrangement in a 'manner', the upper supporting rod is hinged with a pantograph head assembly, the lower supporting rod is hinged with a base assembly, and lifting and falling are realized by adopting a lifting mechanism. The vertical lifting type bipolar pantograph of the public transport trolley bus disclosed in Chinese patent publication No. CN1284037C has a scissor type four-bar mechanism, and electrodes of a pantograph head assembly vertically lift through the scissor type four-bar mechanism. Swing type pantographs as disclosed in fig. 1a and 1b in chinese patent application publication No. CN105339203a, wherein the bow is a swing arm, one end of the swing arm is hinged on the base, the other end is connected with the bow head assembly, and the swing arm is driven to rotate by a corresponding lifting mechanism to realize lifting.
When the pantograph disclosed in the first two patent documents is used under different working conditions and in different environments, the pantograph is directly exposed to the outdoor space, so that the abnormal problems of rain and snow coverage, road side tree scratching and the like can be caused in the vehicle operation process. Such a situation may lead to non-planar contact such as line contact, point contact, etc. between the pantograph and the charging frame plate/charging cable, and damage to the plate, high voltage connection line, contact terminal, etc., thereby leading to increased contact resistance in the non-planar contact area and damaged area, rapid heat accumulation under the condition of large voltage and large current charging, rapid temperature rise, affecting the safety and reliability of charging, and possibly burning out the electrode in severe cases, even damaging the charging system and the vehicle. In order to solve the above-described problem, however, a third patent document proposes a technique in which a cover for covering a pantograph is provided on a vehicle, and the cover can be automatically opened from a protection state to an open state when the vehicle has reached a predetermined charging position. However, the cover needs to be opened by means of a pushing device on a power supply device (such as a charging frame polar plate in a charging station), or by means of a control signal to control an actuator to open the cover, so that the pushing device is required to be arranged on the power supply device, and the direction of the vehicle is adjusted to be aligned with the pushing device when the vehicle enters the charging station, so that the driving difficulty is increased, the charging is inconvenient, or a corresponding actuator and a control circuit thereof are required to be additionally arranged, and the coordination of lifting of a pantograph and opening and closing of the cover is ensured, so that the problems of poor reliability, complex structure and high cost are solved, and the inconvenience is caused to charging.
