Description

Technical Field

[0001] This utility model relates to the field of new energy lithium battery storage and charging piles, and more particularly to an automatic obstacle avoidance mobile charging pile. Background Technology

[0002] With the increasing popularity of new energy vehicles, the flexibility and coverage of charging infrastructure have become critical requirements. Traditional fixed charging piles are limited by their fixed location and service area, confined to charging stations, lacking the flexibility to respond to actual service demands. While existing mobile charging piles possess a degree of mobility, they lack environmental perception and automatic obstacle avoidance capabilities. In complex scenarios (such as old residential areas and parks), mobile charging piles are prone to collisions due to their lack of obstacle avoidance, thus affecting equipment safety. Therefore, there is an urgent need for a mobile charging pile that can move and possesses environmental perception and automatic obstacle avoidance functions to improve the flexibility and safety of charging piles, thereby meeting the actual needs of new energy vehicle charging services.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] This utility model discloses an automatic obstacle avoidance mobile charging station, such as... Figure 1 As shown, it includes a device carrier 1 as the main load-bearing structure, a charger 3 and a battery pack 4 carried by the device carrier 1, drive system components, a computing platform 11, a power module 10, a housing assembly 2 fitted outside the device carrier 1, and an obstacle avoidance system component disposed on the housing assembly 2.

[0024] like Figure 4 As shown, for ease of description, the device carrier 1 is divided into a lower chassis section and an upper frame section. A shock-absorbing wheel 209 with shock-absorbing function is installed at the front end of the chassis section, and an extension platform wheel 210 is installed at the rear end of the chassis section. The extension platform wheel 210 includes an extension platform plate and a motion wheel. The extension platform plate and the chassis section are on the same horizontal plane, and the extension platform plate extends the rear end length of the chassis section. The shock-absorbing wheel 209 and the extension platform wheel 210 provide basic mobility for the device. Bottom limiting brackets 202 for the outer shell are provided on both sides of the chassis section for fixing the outer shell assembly 2.

[0025] A frame is fixed to the upper surface of the chassis section. The frame is assembled from several sheet metal parts. Columns 205 are located on both sides of the front end of the frame. Between the two columns are component mounting plates 207 for supporting drive system components and motor mounting plates 208 for fixing the drive motor 9. Support brackets 206 are located on the inner sides of the front and rear ends of the frame and are arranged in an array along the height direction of the frame. They are used to support the battery pack 4 for storing energy. A side limiting baffle 203 is provided on one side of the frame and is arranged in an array along the height direction of the frame. Several detachable side baffles 204 are provided on the other side of the frame and are arranged in an array along the length direction of the frame. A frame support beam 201 is provided at the top of the frame and is used to support the outer shell assembly 2. The above constitutes the complete frame section.

[0026] The chassis of the device carrier 1 supports the battery pack 4, which is housed inside the frame. Side baffles 204 are installed on the frame to form a closed structure, thereby improving the stability of the battery pack 4 during device operation. The extension platform plate of the extension platform wheels 210 extends the length of the chassis; the extension platform plate is used for supporting and fixing the charger 3, which is located at the rear end of the frame.

[0027] It should be noted that battery pack 4 is an energy storage device that stores electricity needed to power new energy vehicles. Charger 3 is a device that provides charging services to new energy vehicles, and it is compatible with most new energy vehicle interfaces currently on the market. Battery pack 4 connects to energy devices via charger 3 to replenish its power, or connects to a new energy vehicle via charger 3 to charge it, thus realizing the charging and discharging functions of the device. The input and output current of battery pack 4 are both in a high-voltage state, which is regulated to a conventional voltage by the transformer built into charger 3 and output to other system devices. Both the charger and the battery pack are existing mature technologies, and will not be elaborated further in this document.

[0028] To address the limitations of traditional charging stations in terms of service range and the lack of obstacle avoidance capabilities in mobile charging stations, this invention incorporates a drive system and an obstacle avoidance system.

[0029] For the specific locations of the drive system components and obstacle avoidance system components, please refer to... Figure 3 , Figure 4 , Figure 5 and Figure 6The power module 10, computing platform 11, steering controller 5, drive controller 6, contactor 7, and fuse 8 are all mounted on a component mounting plate 207 fixed between the front columns of the frame section. A component protective cover 12 is fixed to the component mounting plate 207 to protect the components. The drive motor 9 at the end of the drive system is fixed to a motor mounting plate 208 at the front of the chassis section. The drive wheel driven by the drive motor 9, along with the shock-absorbing wheel 209 and the extension platform wheel 210, all contact the ground. Furthermore, the laser adapter base 304 in the obstacle avoidance system is located on the upper surface of the frame support beam 201 of the frame section. The outer shell assembly 2, fitted onto the device carrier 1, has mounting holes that mate with the laser adapter base 304. A laser support 305 is fixed at the mounting holes, and the laser support 305 is located on the upper surface of the front end of the outer shell assembly 2, with the laser 301 fixed to it. Furthermore, the marker lights 303 are located on both sides of the upper part of the housing assembly 2, the radar 302 is located on the front and rear edges of the lower part of the housing assembly 2, the front contact edge 306 is located on the front edge of the lower part of the housing assembly 2, and the rear contact edge 307 is located on the rear edge of the lower part of the housing assembly 2.

[0030] Among them, such as Figure 2 As shown, the system logic of this utility model is as follows:

[0031] The power module 10 supplies electrical energy to the drive system and obstacle avoidance system. The power module 10 is connected to the charger 3 carried by the device carrier 1, and thus draws on the stored power in the battery pack 4 connected to the charger 3 to maintain continuous system operation. The power module 10, charger 3, and battery pack 4 together constitute the power system of this device. The power module 10 is connected to the computing platform 11 at its rear end. The computing platform 11 is the control center of the drive system and obstacle avoidance system, used to receive data information from the obstacle avoidance system devices and control the drive system devices to operate along a safe path based on the data information. It should be noted that the computing platform 11 is a general-purpose controller, providing environmental perception, positioning, and navigation functions for the mobile charging pile disclosed in this document. The computing platform 11 is compatible with multiple mainstream LiDARs and provides rich I / O and CAN interfaces for connecting various sensors and driver devices (the computing platform in this embodiment uses the SRC series controller as an example). The power module 10 has a power conversion function, converting the acquired high-voltage current into a current matching the load of the drive system and obstacle avoidance system through common AC-DC or DC-DC mode conversion. The drive system devices and power module 10 are equipped with a fuse 8 and a contactor 7. The contactor 7 is a device for controlling the load and opening / closing of the circuit, and the fuse 8 is a device for protecting the circuit from overload and short circuit. The arrangement of the contactor 7 and the fuse 8 improves the stability and safety of the device drive system.

[0032] Specifically, the power module 10, acting as a power supply, is connected at its rear end to a computing platform 11, which serves as the control center. The rear end of the computing platform 11 is connected to a steering controller 5 and a drive controller 6. The steering controller 5 and drive controller 6 are connected to drive motors 9, which are the end units of the drive system and act as actuators. The computing platform 11 at the front end of the drive system receives data detected by the obstacle avoidance system devices and plans a safe driving path based on this data. Then, the computing platform 11 issues commands to the steering controller 5 and drive controller 6. The controllers, based on these commands, control the drive motors 9 to perform relevant actions, thereby driving the device along a safe path and actively avoiding collisions with obstacles.

[0033] The computing platform 11 receives detection data from obstacle avoidance system devices to plan a safe, obstacle-free path. Specifically, a laser 301 emits laser light into the surrounding environment and receives reflected laser signals, while a radar 302 emits ultrasonic waves and receives reflected ultrasonic signals. Both are located at the front end of the computing platform 11. The computing platform 11 receives and processes data signals from the laser 301 to perceive the surrounding environment and terrain. It also receives and processes data signals from the radar 302 to detect the location of surrounding obstacles. Based on the received data, the computing platform 11 plans a safe driving path. Furthermore, the front end of the computing platform 11 is equipped with a front contact edge 306 and a rear contact edge 307. The safety contact edge is a rubber strip-shaped pressure-sensitive device that transmits signals to the computing platform 11 when the front or rear contact edges are subjected to collision or compression. The computing platform 11 then controls the drive system to stop the device's movement. The obstacle avoidance system also includes a marker light 303, which is directly connected to the power module 10. The marker light is always on to alert other pedestrians, vehicles, etc. to pay attention to and avoid the device, thereby improving the safety of the device when it is in operation.

[0034] In summary, this invention, through the configuration of the drive system, enables autonomous driving. The laser in the obstacle avoidance system allows the device to perceive the surrounding terrain, and the ultrasonic radar further assists in detecting the location of surrounding obstacles, providing data support for the computing platform to plan a safe driving path to avoid collisions. This invention solves the problems of limited service range and insufficient obstacle avoidance capabilities of traditional charging piles, achieving autonomous movement and automatic obstacle avoidance, thus improving the flexibility and safety of charging piles.

[0035] The above embodiments are not intended to limit the present invention, nor is the present invention limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present invention are also within the protection scope of the present invention.
