More specifically, the connection of the strip-shaped third through hole and the positioning piece, the angular contact ball bearing and the connecting shaft are further arranged, so that the self-adaptive adjustment of a plurality of degrees of freedom of horizontal swinging, vertical moving and front-back swinging can be realized according to different stress directions under the action of external forces in different directions by the collector head, the practicability is high, the self-adaptability of the collector head in transition of different rail surfaces is greatly improved, and more stable power receiving performance is realized.
As shown in fig. 6, the collector shoe 100 according to the embodiment of the invention includes a base 20, a connecting arm 30 and a collector head 10, wherein both ends of the connecting arm 30 are respectively hinged with a supporting frame 1 on the base 20 and the collector head 10. Specifically, the collector shoe 100 is adapted to be disposed on a vehicle through the base 20, and the collector head 10 is adapted to receive power in contact with a power supply rail and simultaneously supply power to the vehicle. Through setting up the collecting head 10 of the structure as before here, when the collecting shoe receives the electricity with the power supply rail contact, can realize self adaptive slope swing, even through the great rail surface of slope change, also can be according to the slope situation of change, freely adjust the slope transition angle in real time so that the collecting head adapts to the rail surface in real time, thereby make the collecting head at rail surface smooth transition, applicable in the rail surface of different change slopes, the buffering effect has been improved, thereby the life of collecting shoe has been prolonged, the self-adaptability of collecting head at different rail surface transitions has been improved greatly simultaneously, realize more steady receiving performance.
