Obstacle avoidance device of front sweeping brush system

Abstract

The invention relates to an obstacle avoidance device of a front sweeping brush system. A front sweeping brush system mounting cross arm is fixedly connected to one end of a connecting buckle plate; the other end of the connecting buckle plate is connected with a sweeping vehicle; sweeping brushes are connected to outside rotating shafts of sweeping brush rotating speed motors through flat key sleeves; the obstacle avoidance device is characterized in that each sweeping brush swinging arm system comprises a sweeping brush forearm and a sweeping brush big arm; the sweeping brush forearms are connected with tie bars transversely fixed to the inner side of the front sweeping brush system mounting cross arm; retraction limiting blocks and stretching limiting devices are arranged on the sweeping brush forearms and the sweeping brush big arms; the sweeping brush rotating speed motors are connected to the front ends of the sweeping brush forearms; the back ends of the sweeping brush forearmsare glidingly connected with the sweeping brush big arms through sliding bearings; the sweeping brush big arms are glidingly connected with the front sweeping brush system mounting cross arm through sliding bearings; the retraction limiting blocks of the sweeping brush forearms are arranged at the outer ends of the side surfaces of sweeping brush big arms; the stretching limiting blocks of the sweeping brush forearms are arranged on the sliding bearings at the back ends of the sweeping brush forearms; and the retraction limiting blocks of the sweeping brush big arms are fixed to the inner sides of the two ends of the front sweeping brush system mounting cross arm.

Description

[0001] (1) Technical field [0002] The invention relates to an obstacle avoidance device for a front sweeping brush system. [0003] (2) Background technology [0004] At present, the sweeping brushes of cleaning vehicles on the market cannot avoid obstacles. Due to the special operating environment of cleaning vehicles, cleaning vehicles often encounter obstacles in front of them during operation, and existing cleaning vehicles cannot effectively avoid obstacles. The driver drives the vehicle around to dodge. Once the driver fails to dodge in time, the brush will be damaged due to hitting an obstacle, or even destroy the entire front scanning system. The cleaning vehicles on the existing market do not have effective obstacle avoidance devices. Most of the front sweeping systems are rigidly connected to the cleaning vehicles without swing arm systems, and the so-called obstacle avoidance schemes are implemented by the driver by adjusting the vehicle driving route. Avoidance o...

AI Technical Summary

Problems solved by technology

[0006] 1. Poor maneuverability for obstacle avoidance: The traditional solution relies on the judgment of the driver of the cleaning vehicle to adjust the driving state of the vehicle for obstacle avoidance. This solution relies on traditional human judgment. The forward scanning system itself does not have the ability to avoid obstacles, has no flexibility, and has poor maneuverability

[0007] 2. Passive obstacle avoidance: When cleaning vehicles, encountering obstacles in front of them, the front scanning system itself cannot avoid them. It needs to be passively controlled by the driver of the cleaning vehicle to avoid them, which is very passive.

[0008] 3. Poor obstacle avoidance ability: The traditional solution has high requirements for the experience and response sensitivity of the driver of the cleaning vehicle. Once obstacles appear within the working range of the cleaning vehicle, the driver fails to respond in time, or the driver makes a mistake and the vehicle is cleaned. The front-scanning system will inevitably hit obstacles, so the traditional solution has poor adaptability and poor ability to handle special situations

[0009] 4. Poor operation safety: The front-sweeping system of the traditional solution does not have the ability to automatically avoid obstacles. Once it hits an obstacle head-on or the driver of the cleaning vehicle drives out of the safe area to avoid obstacles, it will cause irreparable consequences. lead to safety accidents

[0010] 5. The front-scanning system lacks a self-protection mechanism: The front-scanning system of traditional cleaning vehicles does not have the function of avoiding obstacles. Once it hits an obstacle or rubs against an obstacle, it will easily cause damage to the front-scanning system. During operation, there is no guarantee Safety and stability of the forward scanning system

[0011] 6. Poor durability and stability of the front-sweeping system: Due to the changeable operating environment of the cleaning vehicle, it often rubs against obstacles such as roadside stones or stones encountered during cleaning, while the traditional front-sweeping system does not have self-obstacle avoidance and obstacle avoidance Angle adjustment and other functions, so over time, the angle of the front brush and the forearm of the front brush will be offset due to frequent scratches or collisions, and the brush will be bumped crookedly. It will change, which will affect the cleaning ability, increase the maintenance cost, and the durability stability of the whole front sweeping system is very poor

[0012] At present, there is no technical innovation and breakthrough in the automatic obstacle avoidance function of the front sweeping system of the cleaning vehicle on the market.
