Detailed Description

The embodiment is an electric bus.

As shown in fig. 1, 2, 3, 4 and 5, the electric vehicle capable of semi-automatically tracking and driving and matching with a power supply contact road comprises an electric connector arranged at the lower part of the vehicle, wherein the electric connector is provided with a first connecting rod (8), a second connecting rod (5), a connecting rod hinged support (6), an electric connector upper plate (7) and a conductive contact sliding plate (4), the first connecting rod (8) and the second connecting rod (5) are respectively hinged with the electric connector upper plate (7), and a strong magnet piece (11) is arranged between the electric connector upper plate (7) and the contact sliding plate (4), and the electric vehicle is characterized in that: the side sliding plate (9) which can conduct electricity is arranged beside the contact sliding plate (4), an insulating layer (10) is arranged between the contact sliding plate (4) and the side sliding plate (9), and a battery, a load, the contact sliding plate (4), the side sliding plate (9) and other electric conductors form a circuit to be communicated.

The electric connector shown in figures 1, 2, 3, 4 and 5 is composed of a left electric connector and a right electric connector, and the flatness of a pair of correspondingly matched contact lines can easily meet the design requirement. The left side electric connector and the right side electric connector can be respectively used for being in sliding contact connection with the contacts of the positive and negative electrodes of the power supply contact road. The small circles shown in fig. 2, 3 and 4 as thin lines and broken lines, respectively, are circular contact surfaces of the contact (1) and the bottom plane of the electric connector when the vehicle is powered by a road contact, and for convenience of description, the small circles are labeled as the contact (1). Fig. 1, 2, 3, 4 and 5 show more clearly that, when the power supply contact road for driving supplies power to the vehicle, the contact (1), the contact sliding plate (4), the side sliding plate (9) and the insulating layer (10) have the shape, size and mutual position relation, and the parallel spacing width of the contact sliding plate (4) and the closer side sliding plate (9) is smaller than the diameter of a small circle. The embodiment is designed as follows: when the vehicle runs, only when the contact (1) touches the contact sliding plate (4) and the side sliding plate (9) at the same time, the battery, the load, the contact sliding plate (4), the side sliding plate (9) and other conductors on the vehicle form a circuit to be communicated, and the load is electrified to work. It is clear that the contact (1), the contact strip (4) and the edge strip (9) form a special electric switch.

As shown in fig. 6, 7 and 8, the load may be an electric motor (16) mounted on the lower side of the steering wheel shaft (12) of the vehicle, the electric motor (16) being drivingly connected to the steering wheel shaft (12) through a gear change mechanism (14). As shown in fig. 1, 2 and 3, the contact sliding plate (4) and the side sliding plate (9) of the left electric connector are a pair of left sliding plates, and the contact sliding plate (4) and the side sliding plate (9) of the right electric connector are a pair of right sliding plates. When the vehicle is deflected to the left and the contact (1) on the left side touches the pair of left side sliding plates simultaneously while the vehicle is running along the contact line, the battery, the load, the pair of left side sliding plates and other electric conductors form a circuit to be communicated at the contact (1) on the left side, the electric motor (16) rotates forwards, the steering wheel shaft (12) is driven to rotate clockwise through the speed change mechanism (14), and the steering wheel turns back to the right. Conversely, when the vehicle is moving along the contact line and the contact (1) on the right side is deflected to the right and touches the pair of right side sliding plates simultaneously, the contact (1) on the right side causes the circuit to be communicated, which is formed by the battery, the load, the pair of right side sliding plates and other conductors, to be communicated, and the electric motor (16) is reversed to drive the steering wheel shaft (12) to rotate counterclockwise through the speed change mechanism (14), thereby turning the steering wheel back to the right. Thus, when the vehicle travels along the contact line, the contact (1) on the left side and the contact (1) on the right side can respectively keep touching with the contact slide plates (4) of the left and right electric connecting devices. Thus, the semi-automatic tracking function for assisting the driver to accurately track the driving of the power supply touch line is realized.

As shown in fig. 6, 7 and 8, in order to reduce the response time of the transmission of the motor (16) and the speed change mechanism (14) after being electrified as much as possible and improve the reliability of the embodiment, the speed change mechanism (14) is a triangle belt transmission device, the material of the triangle belt pulley is engineering plastics with small specific gravity, the tension degree of the triangle belt is adjusted by a spring (18), and the motor (16) is a direct current speed reduction motor with higher voltage and smaller rotational inertia. This easily meets the following design requirements: the torque of the steering wheel shaft (12) driven by the motor (16) is smaller than the torque of the steering wheel driven by the driver according to a set degree, so that the control of the driver on the random strain of the vehicle is not influenced.

As shown in fig. 6, 7 and 8, the motor (16) is mounted on the beam (13) of the electric vehicle, that is, the motor (16) is connected to the vehicle beam (13) through the rocker seat (15) and the bracket (17). This is a low cost reliable device that meets performance requirements.

If the battery, load, contact slide plate (4), side slide plate (9) and other electric conductors on the vehicle form the load in the circuit to be communicated and are wireless signal transmitters, and devices such as a motor (16) and a speed change mechanism (14) for driving a steering wheel shaft (12) do not exist, the semi-automatic tracking function for assisting a driver to accurately track the driving of a power supply contact line is not provided in the embodiment, and only the running electricity information of the contact line for the vehicle is transmitted to let contact line managers know the function: generally, when the vehicle runs by the power supply of the contact wire, the circuit to be connected becomes a circuit disconnected according to the irregular changing frequency, a corresponding electric signal is formed, the electric signal becomes a wireless signal through the wireless signal transmitter and is transmitted, and the contact wire manager can know the signal accordingly. This information can of course be transmitted far enough through the base station to become an internet signal.

If the battery, the load, the touch sliding plate (4), the side sliding plate (9) and other electric conductors on the vehicle form the load in the circuit to be communicated, the electric motor (16) and the wireless signal transmitter jointly form the load. Thus, this embodiment has two important functions: the system has the functions of assisting a driver to accurately track the semi-automatic tracking function of driving the power supply contact line, and transmitting the running electricity utilization information of the contact line for the vehicle to enable contact line managers to know the running electricity utilization information.

Of course, the contact line owner and the power supply department can install an advanced internet remote mobile intelligent electric meter on each contact electric vehicle, and manage the running electricity utilization of the contact line users by remote charging and the like.
