Description
Technical Field

Background
At present, the power supply of the mobile device is generally realized by an electric bow device in an electric contact form, such as a wired trolley bus. The pantograph device of the wired electric vehicle, which includes a pantograph slide plate and a pneumatic mechanism or a spring mechanism, requires a relatively constant contact pressure between the pantograph device and a live bus bar during operation to ensure a continuously stable current collection performance.
At present, the pantograph device is usually in contact with a live bus in a solid sliding electrical contact manner, that is, a pressure is applied to a surface of the pantograph slider, which is in contact with the live bus, through a pneumatic mechanism or a spring mechanism, so that the pantograph device and the live bus are electrically connected, and current flows from the power supply bus to the pantograph device and then flows from the pantograph device to the current-collecting equipment for power supply. Because the pantograph device and the current-collecting equipment are mechanically connected together and the relative position is unchanged, the current-collecting equipment can still adopt a common cable connection mode to take power from the pantograph device although moving relative to the bus.
In the process of implementing the invention, the inventor finds that the prior art has at least the following problems:
because the contact pressure between the pantograph slide plate and the bus is usually maintained by a pneumatic mechanism or a spring mechanism, once the contact pressure between the pantograph slide plate and the bus is too small, poor contact between the pantograph device and the bus can be caused, the power supply is interrupted, even sparks or electric arcs are caused, and the bus is burnt; if the contact pressure between the pantograph slide plate and the bus is too large, the contact surface of the pantograph slide plate is abraded too fast, and the service life of the pantograph slide plate is shortened. Even if the contact pressure between the pantograph slide plate and the bus is ensured to be proper during installation, the electric contact effect between the pantograph device and the bus is reduced due to factors such as bumping of the trolley, stains on the surface of the pantograph slide plate and the like during use, so that the contact pressure between the pantograph device and the electrified bus cannot be ensured to be constant by the traditional solid sliding electric contact mode, and the continuous and stable current collection performance of the current collection equipment is ensured.
