Abstract

The invention discloses an automatic obstacle avoidance detection mechanism for a multifunctional environmental sanitation electric vehicle, comprising a system main controller, a snow removal shovel (1), a snow shovel support rod (2), a spring baffle (3), and an obstacle avoidance detection mechanism (4 ), spring (6), support rod holder (7), support rod sliding sleeve (8) and support rod fastening screw (9). The obstacle avoidance detection mechanism (4) uses a travel switch to detect whether the snow shovel (1) encounters an obstacle. The travel switch is connected to the main controller of the system. If the snow shovel (1) encounters an obstacle, the spring (6) will Contraction, the limit switch is closed, the pin connected to the limit switch of the system main controller becomes low level, and the system main controller controls the motor to realize active obstacle avoidance. The invention can not only realize the function of clearing thin snow on the ground, but also realize the active obstacle avoidance function of the vehicle, and avoid the motor stalling caused by the sanitation vehicle encountering obstacles.

Description

A multifunctional sanitation electric vehicle automatic obstacle avoidance detection mechanism

technical field

The invention relates to the field of automatic obstacle avoidance in snow removal, in particular to a detection mechanism for automatic obstacle avoidance of a multifunctional environmental sanitation electric vehicle.

Background technique

As the pace of urbanization continues to accelerate, the city's basic supporting facilities are becoming more and more perfect, and people's quality of life is also constantly improving. The development of urbanization and the increase of population have brought us a large amount of construction and domestic waste in recent years, seriously affecting our living environment and city appearance. As labor costs have increased year by year with the rapid economic growth in recent years, relying solely on manpower to maintain urban environmental sanitation will not only increase government financial pressure, but also be inefficient.

An automatic obstacle avoidance detection mechanism for a multifunctional environmental sanitation electric vehicle is an automatic obstacle avoidance detection mechanism provided to prevent the drive motor from stalling when the snow removal shovel of the environmental sanitation electric vehicle cannot move forward due to an obstacle.

Contents of the invention

In view of the above situation, the present invention aims to provide a mechanism capable of obstacle avoidance detection, so as to prevent the driving motor of the sanitation electric vehicle from being blocked and causing adverse consequences to the motor.

A multifunctional sanitation electric vehicle automatic obstacle avoidance detection mechanism, including a system main controller, a snow removal shovel 1, a snow shovel support rod 2, a spring baffle 3, an obstacle avoidance detection mechanism 4, a spring 6, a support rod fixing frame 7, a support Rod sliding sleeve 8 and support rod fastening screw 9; the snow shovel 1 is connected with the snow shovel support rod 2, and the snow shovel support rod 2 is connected with the spring baffle 3; the obstacle avoidance detection mechanism 4 is installed on the spring baffle 3 Above, the main component of the obstacle avoidance detection mechanism 4 is a travel switch, which is connected to the main controller of the system; the spring 6 is set outside the snow shovel support rod 2 and installed between two spring baffles 3; The supporting rod fixing frame 7 is connected with the vehicle chassis; the supporting rod sliding sleeve 8 is connected with the supporting rod fixing frame 7, and the snow shovel supporting rod 2 can move in the supporting rod sliding sleeve 8; the supporting rod fastening screw 9 is installed on the snow shovel support bar 2 ends.

The travel switch is installed at one end of the spring baffle 3. When the snow shovel 1 in front of the vehicle encounters an obstacle and cannot move forward, the snow shovel support rod 2 of the snow shovel 1 shrinks back at this time, and the spring 6 shrinks at the same time, forcing The travel switch is closed, and when the corresponding pin of the main controller of the system detects a low level, the motor is controlled to stop running, and then the motor is driven in reverse to reverse. After separation, the main controller turns off the output of the speed and gear signals, and waits for the next command to control the operation of the vehicle.

The invention can not only realize the function of clearing thin snow on the ground, but also realize the active obstacle avoidance function of the vehicle, and avoid the motor stalling caused by the sanitation vehicle encountering obstacles.

detailed description

As shown in Fig. 1, a kind of automatic obstacle avoidance detection mechanism of multifunctional environmental sanitation electric vehicle of the present invention comprises system main controller, snow removal shovel 1, snow shovel support bar 2, spring baffle plate 3, obstacle avoidance detection mechanism 4, spring 6. Support rod fixing frame 7, support rod sliding sleeve 8 and support rod fastening screw 9; the snow removal shovel 1 is connected with the snow shovel support rod 2, and the snow shovel support rod 2 is connected with the spring baffle 3; obstacle avoidance The detection mechanism 4 is installed on the spring baffle 3, and the main component of the obstacle avoidance detection mechanism 4 is a travel switch, which is connected with the main controller of the system; the spring 6 is set outside the snow shovel support rod 2 and installed on two springs Between the baffles 3; the support rod fixing frame 7 is connected with the vehicle chassis; the support rod sliding sleeve 8 is connected with the support rod fixing frame 7, and the snow shovel support rod 2 can move in the support rod sliding sleeve 8 ; The support rod fastening screw 9 is installed at the end of the snow shovel support rod 2.

The travel switch is installed at one end of the spring baffle 3. When the snow shovel 1 in front of the vehicle encounters an obstacle and cannot move forward, the snow shovel support rod 2 of the snow shovel 1 shrinks back at this time, and the spring 6 shrinks at the same time, forcing The travel switch is closed, and when the corresponding pin of the main controller of the system detects a low level, the motor is controlled to stop running, and then the motor is driven in reverse to reverse. After separation, the main controller turns off the output of the speed and gear signals, and waits for the next command to control the operation of the vehicle.

The present invention has been introduced in conjunction with the above practical examples, but the present invention is not limited to the above specific implementation manners, and methods similar to the present invention in principle and thought are within the protection scope of the present invention.
