Description

Technical Field

[0001] The utility model belongs to the technical field of safety management of electric loaders, in particular to an intelligent safety control system for electric loaders. Background Art

[0002] Electric construction machinery is gradually emerging in the new energy sector. Electric loaders are a prime example of this type of machinery. With recent advancements, electric loader technology has evolved, moving from primarily fulfilling basic functions to automation and intelligent systems. Simultaneously, the safety of electric construction machinery is receiving increasing attention. Against this backdrop, this utility model addresses this issue by developing intelligent safety warning and collision avoidance features for loaders, enhancing their safety and reliability.

[0003] The operational safety of current electric loaders is essentially determined by the driver's operating intentions, and the overall vehicle safety remains at the level of traditional fuel loaders. The braking system of current electric loaders uses a single-circuit braking system. During vehicle operation, if an obstacle or emergency situation occurs, the electric loader can only stop after the driver steps on the brakes. The driver's subjective factors have a significant impact on vehicle operational safety. At the same time, because electric vehicles have a faster torque response than gasoline vehicles, coupled with the driver's reaction time, the operational safety of electric loaders is further restricted. Currently, during electric loader operation, the driver is completely responsible for observing the surrounding operating environment and manually judging whether the operation is safe. This can easily lead to safety accidents due to blind spots and the influence of subjective factors. Utility Model Content

[0025] Example 1

[0026] Refer to the attached Figure 1 This embodiment of an intelligent safety control system for an electric loader includes a radar 110 and a camera 120 for collecting vehicle environmental information. The radar 110 and camera 120 are communicatively connected to a VCU 200. The system also includes a dual-circuit brake system 310, an alarm system 330, and an electric drive system 320. The dual-circuit brake system 310 includes a brake pedal air brake valve circuit and an electric proportional air brake solenoid valve circuit. The brake pedal air brake valve circuit is used for driver braking, and the electric proportional air brake solenoid valve circuit is connected to the electric drive system 320 for automatic braking. The alarm system 330 and the electric drive system 320 are communicatively connected to the VCU 200. By combining the radar 110 and camera 120, the system of this embodiment can fully collect information about the vehicle's vicinity. The VCU can control the electric drive system 320 to actively brake the dual-circuit brake system 310 based on the data collected by the radar 110 and camera 120, effectively improving the safety of the loader vehicle during operation.

[0027] The dual-circuit braking device 310 is also equipped with an air pressure sensor 130 for detecting air pressure in the circuit. The air pressure sensor 130 is communicatively connected to the VCU 200. The radar 110 is also connected to a radar controller, which is communicatively connected to the VCU 200 and converts the pseudo-signal collected by the radar 110 into a distance value and transmits it to the VCU 200.

[0028] The radar 110 and the camera 120 are respectively arranged on the left side, right side and rear side of the vehicle.

[0029] The alarm device 330 includes a warning light and a buzzer. The alarm device 330 receives the warning instruction from the VCU 200 and starts working, and adjusts the warning frequency according to the warning instruction.

[0030] The workflow of the VCU200 includes:

[0031] Detect whether the vehicle's operating status is normal, monitor the data collected by the radar 110 in real time and determine whether there are people or obstacles entering the preset warning area; when it is found that there are people or obstacles entering the preset warning area, send a warning instruction to the alarm device 330 and / or issue a braking instruction to the electric drive device 320.

[0032] When the dual-circuit brake device 310 is working, the VCU 200 monitors the air pressure analog signal detected by the air pressure sensor 130 and converts it into an air pressure value and brake opening, and performs regenerative braking of the vehicle according to the current vehicle status information and the size of the brake opening.

[0033] The VCU 200 divides the area into danger zone, warning zone, and safe zone according to the distance from the vehicle. The VCU automatically adjusts the area range of the danger zone and warning zone based on the data from the radar 110 and the camera 120. When the camera 120 detects a moving person, the VCU 200 adjusts and expands the area range of the danger zone and warning zone.

[0034] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
