    TERRITORY
    The present application relates to the technical field of power supply for fast charging, in particular a pantograph head device for fast-charging electric vehicles, such as. B. Energy storage type electric buses.
    BACKGROUND
    With social development, development concepts for urban rail transport such. B. energy savings and environmental protection, constantly improved and accordingly electric buses of the energy storage type are used. The so-called energy storage type electric bus uses a supercapacitor to store electrical energy as the driving force, includes pantographs to collect electricity and current return and quickly charges within a few dozen seconds while passengers get on or off at the stop. A single charge can ensure that the electric bus of the energy storage type can travel to the next stop to be recharged. Such vehicles are popularized and used more and more only because of the above features.
    The current collector is installed on top of an energy storage bus and is a current collector device for charging the energy storage bus. When the energy storage bus is parked at a charging station, the pantograph is raised and a pantograph head comes into contact with an energy supply rail of the charging station, whereby the energy storage bus is charged.
    The current collector head of the current collector of an energy storage trolleybus must have at least contacts or contact plates for three electrodes, ie. H. a positive electrode, a negative electrode and a ground electrode must be arranged and must have three electrodes, i. H. a positive electrode, a negative electrode and a ground electrode, correspond to the charging station. The parking position of the / 25 • · ····· · · · ···· · · · · • ·· · · ·· ·· · · • · · · ·· ·· · · ·

    However, trolleybuses vary each time, so designing the pantograph head device takes parking deviations into account, including deviations in the lateral displacement of the vehicle, a longitudinal yaw angle of the vehicle and a slight shaking of the vehicle body when passengers get on and off.
    A conventional current collector head has a large volume and only one degree of rotation. In the event of a large parking deviation, it cannot be ensured that all electrodes are in reliable contact and electrical sparks often occur during charging, which burns the power supply rail and the pantograph head assembly.
    Therefore, a technical problem to which those skilled in the art address is an improvement in the accuracy and reliability of the contact between the current collector head and the power supply rail.

    Attaching and tightening a nut achieved. Another end of the connecting rod 32 is provided with a step which is connected by a rod sleeve 35 to an inner ring of the universal bearing 33, an outer ring of the universal bearing 33 being connected to the pantograph mounting plate 34 by a screw.
    The guide arrangement 4 is designed in the form of a wheel disc, a wheel disc holder 41 of the guide arrangement 4 having six radial support arms 42 which extend outward in a circumferential direction, a tail end of each support arm 42 being provided with a support disc 43. The carrier disk 43 has an upper side which is arc-shaped upwards, around its highest center there is a ball 44 (or a roller) which can roll freely. A guide assembly mounting plate 36, which extends rearward in the form of a cantilever, is fixed to the center of an upper surface of the pantograph assembly mounting plate 34 with a screw, and the wheel disc bracket 41 is fixed to an upper surface of the guide assembly mounting plate 36. The wheel disc can cooperate with the roof to limit a height of the current collector electrode in one aspect, and in another aspect it can move the charging electrodes along the roof by means of the balls.
    A spring restoration device is also mounted on the support frame 31. First spring restoring device elastic support pins 51, which are mounted at positions above the universal bearing in the horizontal direction on the left and right sides respectively, have fixed ends connected to the support frame 31 and telescopic ends supported on the pantograph assembly mounting plate 34 , Second elastic support pins 52 of the spring restoration device are located at positions below the universal bearing in a horizontal direction on the left and right sides, respectively, and have fixed ends which are fixed to the support frame 31 and telescopic ends which are supported on the current collector mounting plate 34.

    Roof of the charging station and the side pantograph assembly 2 is not in contact with the charging electrodes, i. H. if no external force acts on the side pantograph arrangement 2.
    The current collector head with the construction of a universal ball joint can ensure that the electrodes have a multidirectional degree of freedom and can ensure a more stable fit of the electrodes to the charging electrodes and a high quality current draw. In addition, the spring restoration device enables the current collector head to be kept in an initial state when not in use, thereby compensating for the lack of a universal ball joint.
    Reference is now made to FIG. 10, which is a perspective view of the current collector head device of FIG. 1 seen from a front side.
    As shown in the figure, the side current collector assembly 2 is mainly composed of an insulating separator 21, a buffer 22 and an electrode 23 and is a component through which the current collector head is in contact with the charging electrode and is transmitted through the current therebetween. The insulating separator 21 between the side pantograph arrangement 2 and the rotatable connecting element 3 ensures the insulating property of the energy storage bus body and the pantograph. A threaded sleeve is embedded in the insulating separator 21 in advance so that the insulating separator 21 is connected to the pantograph assembly mounting plate 34 of the rotatable connector 3 by a screw.
    The number of electrodes 23 is four, and the four electrodes 23 are a positive electrode, a negative electrode, a ground electrode and a signal electrode, of which the signal electrode is an optional configuration and the other three electrodes are indispensable configurations. During operation, a charging current flows across the positive electrode, through a high voltage cable and an energy storage power supply of the bus and then flows out through the negative electrode to form a charging circuit. The ground electrode is connected to a frame structure of the pantograph and the body of the energy storage bus in order to act as grounding protection.
    The electrodes 23 are made of conductive material, four transverse electrodes being integrated on the insulating separator 21, and they are arranged in parallel one after the other, / 444 · * ·· • 444 4 44 «• · 4 · 4 · · 4 • •• 4 4 4 ··

    21606-PCTAT12 being spaced from top to bottom on an outer surface of the insulating separator 21. The electrodes are of the same length and have contact surfaces that are on the same vertical plane. The electrodes 23 extend on one side in the longitudinal direction of the insulating separator 21 by a certain distance beyond the insulating separator 21.
    Two buffers 22 are placed between each electrode 23 and the insulating separator 21 to provide a buffer when the electrode 23 is in contact with the charging electrode. Each of the buffers 22 includes a telescopic rod 221, a housing 222, and a spring (not shown because it is hidden) configured to connect the telescopic rod 221 to the housing 222 within the housing 222. The housing 222 is connected to the rear surface of the corresponding electrode 23, and the telescopic rod 221 is connected to the insulating separator 21.
    Four transition plates 24 are spaced by screws on the insulating separator 21, and the buffers 22 are connected to the transition plates 24 by screws. Two buffers for each electrode are connected by two connectors. Ends of the first connector 25 and the second connector 26, which face each other, are hinged together, with another end of each of the first connector 25 and the second connector 26 being hinged to a corresponding buffer 22 and a central portion of the first Connector 25 and the second connector 26 is pivotally connected to the transition plate 24. Two buffers 22 are connected to one another via a connector mechanism, as a result of which synchronous buffering is implemented and a blocking error due to unevenly distributed forces is prevented.
    The use of the isolating separator 21 addresses the issue of electrical insulation of the pantograph head and makes the structure simple so that the pantograph head can be smaller and lighter. A spring shock absorber structure is used on two sections of the pantograph head, thereby preventing structural failure due to an impact and improving the reliability and lifespan of the pantograph head.
    Reference is now made to Figure 11, which is a reference drawing showing the current collector head device according to the present application during use.

The pantograph 10 of the vehicle 9 is mounted on the roof in a manner that it is orthogonal to the longitudinal direction of the vehicle body to cause the pantograph head 7 to perform a lifting movement and a transverse movement.
    When the vehicle 9 enters a stop and the current collector head 7 of the current collector is to come into contact with the contact rail 6, the current collector head 7 travels approximately vertically in a vertical plane orthogonal to a longitudinal direction of the vehicle body.
    When the current collector head 7 rises to a height of 1500 mm, the wheel disk of the current collector head 7 comes into contact with the guide plate 8 of the energy charging station and does not move up because it is limited by the guide plate 8, and as a further effect of the driving force, the six come Balls 44 on the wheel disc are fully in contact with the guide plate 8, and later the current collector head 7 starts to move outward in a vertical plane orthogonal to the longitudinal direction of the vehicle body while it is in contact with the guide plate 8, and the current collector head 7 is movable in a range from 0 mm to 700 mm until it comes into contact with the contact rail 6 and lies closely against the contact rail 6, whereby a pantograph condition is achieved.
