Description

Technical Field

[0001] This invention relates to the field of bus technology, and more specifically, to a temporary charging method for temporary charging of driverless buses. Background Technology

[0002] Driverless buses powered by pure electricity inevitably require charging, and the charging situation is related to the age of the battery. Batteries that have been used for a longer period of time will require more charging times. Driverless buses need to run back and forth on corresponding routes. If the route is busy, the number of bus cycles will be even greater. If the vehicle's battery is insufficient during the bus's cycle, it will affect the normal operation of the vehicle. Therefore, under normal circumstances, the bus will be charged at the depot and will only enter the operation state when the battery is sufficiently charged.

[0003] This invention aims to solve the problem that driverless buses need to wait at a depot to recharge when their battery is low during operation. It enables driverless buses to maintain sufficient battery power during operation, achieving uninterrupted cyclical operation, reducing the bus's charging waiting time, and improving the bus's operational efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a temporary charging method for driverless buses, in order to solve the technical problems of ensuring the continuity of driverless bus operation, preventing insufficient power during operation, and avoiding excessively long charging waiting time for driverless buses in the return depot.

Detailed Implementation

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0036] Example 1:

[0037] Reference Figure 1-4 As shown, a temporary charging method for temporary charging of an unmanned bus 200 includes an unmanned temporary battery vehicle 100 and an unmanned bus 200.

[0038] The unmanned temporary battery vehicle 100 includes a battery body 110, a drive chassis 120 mounted on the lower end of the battery body 110, a control unit mounted on the upper end of the battery body 110, and an identification mechanism 140 mounted on the upper end of the control unit.

[0039] Reference Figure 2 and Figure 4 As shown, the driverless bus 200 includes a vehicle body 210 and a receiving cavity 220 installed at the rear of the vehicle body, suitable for housing a driverless temporary battery vehicle 100. The driverless temporary battery vehicle 100 is placed inside the receiving cavity 220.

[0040] Preferred, refer to Figure 1 As shown, the drive chassis 120 includes a drive housing 121, a drive wheel 1224 group 122 mounted on the lower end of the drive housing 121, and an obstacle avoidance sensor 123 mounted on the drive chassis 120.

[0041] Preferably, the drive wheel 1224 group 122 includes a rotary motor 1221 fixedly installed at the four corners of the inner cavity of the drive housing 121, a connecting frame 1222 installed at the output end of the rotary motor 1221 and extending out of the drive housing 121, a drive motor 1223 installed at the lower end of the connecting frame 1222, and a drive wheel 1224 installed at the output end of the drive motor 1223.

[0042] The rotary motor 1221 can realize the directional rotation of the drive wheel 1224, and the drive motor 1223 realizes the rotation of the drive wheel 1224. Through the cooperation of the rotary motor 1221 and the drive motor 1223, the drive wheel 1224 can be steered, so that the unmanned temporary battery vehicle 100 can be smoothly moved to the receiving cavity 220.

[0043] Preferably, the control body includes a main shell 131 mounted on the upper end of the battery body 110, a smart terminal 132 mounted in the inner cavity of the main shell 131, a signal transmitter 133 mounted in the inner cavity of the main shell 131 and electrically connected to the smart terminal 132, a signal receiver 134 mounted in the inner cavity of the main shell 131 and electrically connected to the smart terminal 132, and a speaker 135 mounted on the main shell 131.

[0044] When there is a movable obstacle ahead, a warning to avoid it will be broadcast through speaker 135.

[0045] The obstacle avoidance sensor 123 transmits obstacle information to the intelligent terminal 132, which then makes a judgment and analysis.

[0046] Preferably, the identification mechanism 140 includes an infrared thermal imager 141, a lidar sensor 142, and an ultrasonic sensor 143.

[0047] During the movement of the unmanned temporary battery vehicle 100, the identification mechanism 140 remains continuously activated to support the movement of the unmanned temporary battery vehicle 100.

[0048] Preferred, refer to Figure 3 As shown, a lifting component 230 is provided at the lower end of the receiving cavity 220 of the driverless bus 200;

[0049] The lifting assembly 230 includes telescopic devices 231 installed at both ends of the lower end face of the receiving cavity 220, and a lifting plate 232 installed between the two telescopic devices 231.

[0050] Preferably, the inner wall of the receiving cavity 220 is equipped with a charging port 221 that is connected to the unmanned temporary battery vehicle 100, and an electromagnetic lock 222 is also installed on the inner wall of the receiving cavity 220.

[0051] Preferably, a charging head 111 that cooperates with the charging port 221 is installed on the battery body 110, and a lock head 112 that cooperates with the electromagnetic lock 222 is also installed on the battery body 110.

[0052] The charging port 221 can be, but is not limited to, an electromagnetic charging port, which can fix and release the charging head by being energized and de-energized. The electromagnetic structure can be used to fix the unmanned temporary battery vehicle 100 to the housing cavity 220.

[0053] Preferably, the upper end of the battery body 110 is also provided with a warning light 113. The warning light 113 remains continuously lit while the unmanned temporary battery vehicle 100 is moving.

[0054] Preferably, the control unit is also equipped with a monitoring mechanism 136. The monitoring mechanism 136 remains continuously activated during movement.

[0055] Optionally, the monitoring mechanism 136 will also be triggered to start when the unmanned temporary battery vehicle 100 is subjected to a shock.

[0056] The working process of the lifting component 230 is as follows:

[0057] When the driverless bus 200 needs to replace the driverless temporary battery vehicle 100, the electromagnetic lock 222 loses power and unlocks, the charging head 111 disconnects from the charging port 221, and the lifting assembly 230 starts to descend, causing the driverless temporary battery vehicle 100 to fall to the ground. The driverless temporary battery vehicle 100 then travels to the charging station at the platform, while the driverless temporary battery vehicle 100 on the platform travels onto the lifting plate 232 of the lifting assembly 230. After the lifting assembly 230 raises the driverless temporary battery vehicle 100 into the receiving cavity 220, the electromagnetic lock 222 is energized and locked, and the charging head 111 and the charging port 221 are connected to continue providing charging services for the driverless bus 200.

[0058] In this embodiment, the smart terminal 132 is electrically connected to the signal transmitter 133, the signal receiver 134, the identification mechanism 140, the rotating motor 1221, the drive motor 1223, the horn 135, the monitoring mechanism 136, and the collision sensor.

[0059] The battery body 110 provides power to the smart terminal 132, signal transmitter 133, signal receiver 134, identification mechanism 140, rotation motor 1221, drive motor 1223, horn 135, monitoring mechanism 136 and collision sensor.
