Description

Overhead Charging System for Pantograph Electric Buses

technical field

The utility model belongs to the technical field of urban public transportation, and in particular relates to an overhead charging system for a pantograph type electric bus.

Background technique

With the vigorous development of new energy vehicles, the requirements for charging systems are getting higher and higher. A mature charging system must be safe, stable, convenient and cost controllable. At present, there are two main methods for charging new energy pure electric buses. One is that DC chargers charge pure electric buses through charging guns; Pure electric bus charging. The first method is relatively cumbersome to operate, and a designated charging person must operate the charger and plug and unplug the charging gun for each charging, which is poor in convenience and low in safety. The second method puts the collector device on the roof of the vehicle, and the driver charges through the lifting bow button in the driver's cab. The operation is safe and simple, and it makes up for the poor convenience and low safety of the first method. A power collector is installed on the bus, which increases the weight of the vehicle itself, reduces the performance of the vehicle, and greatly increases the cost of the vehicle factory.

Utility model content

The technical problem to be solved by the utility model is to provide an overhead charging system for a pantograph type electric bus with convenient operation and low cost.

The technical scheme of the utility model is as follows: a pantograph-type electric bus overhead charging system, characterized in that: a pantograph is installed on the top of the platform support, and the pantograph includes a chassis, an electric push rod, an arm rod and The bow head, the bottom frame is suspended and fixed on the platform bracket, and the arm bar is arranged on the bottom frame. The bow head is installed on the suspended end of the arm bar. The lifting and lowering are driven by electric push rods, which are mounted on the chassis.

With the above technical scheme, the bipolar contact rail matched with the bow head is arranged on the roof of the pure electric bus. The arm rod works under the drive of the electric push rod, and has two states of stowing and putting down. When it needs to be charged, the pure electric bus drives into the platform and is located directly under the pantograph. The driver presses the charging button, and the electric push rod starts to move after receiving the command, and pushes the arm of the pantograph downwards to make the arm Put down the bow head of the rod, and when the bow head is in reliable contact with the bipolar contact rail, the platform starts to be powered on, and the pure electric bus starts to charge at this time. Power-off process: When the driver presses the stop button, the platform cuts off the main circuit power supply, and the electric push rod starts to move after receiving the command, so that the arm can be retracted upwards, and the entire charging process is completed, and the vehicle can drive out of the platform. The utility model has the advantages of simple structure, convenient operation and good safety. Each vehicle only needs to install one pair of contact guide rails, so that the weight of the vehicle is reduced and the cost is greatly reduced.

The root of the arm is fixed to the middle of the rotating shaft, and the rotating shaft is perpendicular to the arm. Both ends of the rotating shaft are supported by bearings and bearing seats and the bottom frame. A first swing arm is fixed on the rotating shaft. A swing arm is connected with the output end of the electric push rod. The above structure can ensure that the arm only rotates in the vertical plane, and the arm operates flexibly and has good reliability.

A booster spring is arranged on the underframe, one end of the booster spring is hinged with the underframe, the other end of the booster spring is hinged with the second swing arm, and the second swing arm is fixed on the rotating shaft, and the second swing arm and The first swing arm is separated on either side of the boom. The booster spring provides boost for the operation of the boom, making the boom move more quickly.

Four insulators distributed in a rectangular shape are fixed on the platform support, and the bottom frame is respectively fixedly connected with the four insulators through four bolts. The above structure can realize the fixing of the pantograph and the insulation treatment of the pantograph and the platform at the same time, which not only has good safety, but also has good installation reliability of the chassis.

Beneficial effects: the utility model has ingenious design, simple structure, and easy implementation. The pantograph is arranged on the platform support, and the bipolar contact rail is installed on the roof of the pure electric passenger car. Each vehicle only needs to install one pair of contact rails. On the one hand, the weight of the vehicle is reduced, and the cost is greatly reduced. On the other hand, the operation is convenient, and the safety and stability are good.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

As shown in Figure 1, Figure 2, and Figure 3, the pantograph 3 is suspended and installed on the top of the platform support 1. Head 10, rotating shaft 11, first swing arm 12 and second swing arm 13 etc. constitute. Wherein, the underframe 6 is a frame structure, and the four corners of the top surface of the underframe 6 are designed as installation points. Four insulators 2 distributed in a rectangle are fixed on the platform support 1. These four insulators 2 are on the same horizontal plane, and the four insulators 2 correspond to the four installation points on the top surface of the chassis 6 one by one. The chassis 6 is installed The point is fixedly connected with the corresponding insulator 2 by bolts.

As shown in Fig. 1, Fig. 2 and Fig. 3, an arm bar 9 is set on the base frame 6, and a bow head 10 is installed on the suspended end of the arm bar 9, and the bipolar contact rail 15 matched with the bow head 10 is arranged on the pure electric common The roof of the car 14. The root of arm bar 9 is fixed with the middle part of rotating shaft 11, and rotating shaft 11 is perpendicular to arm bar 9, and the two ends of rotating shaft 11 are all supported by bearing and bearing seat and underframe 6. A first swing arm 12 is fixed on the rotating shaft 11, and the first swing arm 12 is connected with the output end of the electric push rod 7. Rod 7 drives. A booster spring 8 is arranged on the bottom frame 6 , one end of the booster spring 8 is hinged to the bottom frame 6 , and the other end of the booster spring 8 is hinged to the second swing arm 13 .
