[0002] A floor scrubber is a cleaning machine that is suitable for cleaning hard floors while sucking out wastewater and taking it away from the site. It has the advantages of being environmentally friendly, energy-saving, and highly efficient. Floor scrubbers are divided into semi-automatic floor scrubbers, fully automatic floor scrubbers, hand-push floor scrubbers, and ride-on floor scrubbers. In the process of washing floors in ride-on floor scrubbers, the lifting structure of the brush plate plays a key role, which is used to adjust the distance between the brush plate and the ground.
[0003] In the prior art, the lifting structure of the brush disc of a ride-on floor scrubber is directly fixed to the base frame. When the height adjustment of the brush disc is completed during operation, it is easy to collide with the uneven ground. At this time, the impact force generated by the collision is directly transmitted to the lifting structure, thereby causing damage to the lifting mechanism, resulting in equipment damage or reduced work efficiency. Therefore, an anti-collision device for the lifting structure of the brush disc of a ride-on floor scrubber is proposed to solve the above problem.
[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content
[0005] In order to solve the problem that the fixed brush disc lacks an anti-collision buffer structure, so that the impact force generated by the collision is directly transmitted to the lifting structure, thereby causing damage to the lifting mechanism, the present application provides an anti-collision device for the lifting structure of the brush disc of a riding floor scrubber.
[0006] The anti-collision device of the brush plate lifting structure of a ride-on floor scrubber provided in the present application adopts the following technical solution:
[0007] An anti-collision device for a brush plate lifting structure of a ride-on floor scrubber comprises a chassis, a chassis is arranged below the middle section of the chassis, two brush plates are rotatably connected to the bottom outer wall of the chassis, an L-shaped bracket is fixedly connected to the top middle section outer wall of the chassis, an electric push rod is hingedly connected to the top end of the L-shaped bracket, a chain is installed at the output end of the electric push rod, and one end of the chain away from the L-shaped bracket is connected to the middle section outer wall of the chassis through a buffer assembly;
[0008] The buffer assembly includes a U-shaped piece fixedly connected to the top outer wall of the middle section of the chassis, a connecting block is installed inside the U-shaped piece, the top end of the connecting block passes through the U-shaped piece and is movably connected to an end of the chain away from the electric push rod, and a buffer spring is installed on the outer wall of the connecting block located inside the U-shaped piece.
[0009] Preferably, the inner wall of the L-shaped bracket is rotatably connected to a movable bearing via a fixed shaft, and the chain is laid on the outer wall of the movable bearing.
[0010] Preferably, two driving motors are fixedly mounted on the top outer wall of the chassis, and the output shaft ends of the driving motors penetrate the chassis and are fixedly connected to the brush plate.
[0011] Preferably, the bottom outer wall of the base frame is rotatably connected to a plurality of connecting arms, the top outer wall of the chassis is fixedly connected to a plurality of fixing members, and one end of the connecting arm away from the base frame is hinged to the fixing member.
[0012] In summary, this application includes the following beneficial technical effects:
[0013] By means of the arranged L-shaped bracket, electric push rod and chain, the lifting and lowering movement of the chassis can be realized. After the height position of the chassis is adjusted and fixed, when the chassis collides with the uneven ground, the impact force generated drives the chassis to vibrate and move up and down through the buffer assembly. When the chassis moves up, it pushes the U-shaped part and the connecting block to move up. At this time, the chain is deformed, which can prevent the impact force from being suddenly transmitted to the electric push rod. When the chassis moves down, the U-shaped part will be pulled to move the U-shaped part downward. The U-shaped part and the connecting block cooperate to squeeze the buffer spring, and the deformation of the buffer spring generates elastic force. The elastic force generated by the deformation of the buffer spring is used to buffer the chassis, thereby effectively preventing the chassis from being pulled down suddenly, causing structural damage to the electric push rod, and achieving an anti-collision effect.

[0019] The following is combined with Figure 1-4 This application is described in further detail.
[0020] The present application embodiment discloses an anti-collision device for the lifting structure of the brush plate of a ride-on floor scrubber. Figure 1-4 , an anti-collision device for a brush plate lifting structure of a ride-on floor scrubber, comprising a chassis 1, a chassis 4 is arranged below the middle section of the chassis 1, two brush plates 5 are rotatably connected to the bottom outer wall of the chassis 4, an L-shaped bracket 7 is fixedly connected to the outer wall of the top middle section of the chassis 1, an electric push rod 8 is hinged to the top end of the L-shaped bracket 7, a chain 9 is installed at the output end of the electric push rod 8, and one end of the chain 9 away from the L-shaped bracket 7 is connected to the outer wall of the middle section of the chassis 4 through a buffer assembly;
[0021] The buffer assembly includes a U-shaped member 11 fixedly connected to the top outer wall of the middle section of the chassis 4, a connecting block 12 is installed inside the U-shaped member 11, the top end of the connecting block 12 passes through the U-shaped member 11 and is movably connected to an end of the chain 9 away from the electric push rod 8, and a buffer spring 13 is installed on the outer wall of the connecting block 12 located inside the U-shaped member 11.
[0022] The inner wall of the L-shaped bracket 7 is rotatably connected to a movable bearing 10 through a fixed axis, and the chain 9 is laid on the outer wall of the movable bearing 10. When the chain 9 moves up and down, it will drive the movable bearing 10 to rotate. The movable bearing 10 converts the direct friction between the chain 9 and the L-shaped bracket 7 into rolling friction, thereby reducing friction and reducing the wear of the L-shaped bracket 7 and the chain 9.
[0023] Two driving motors 6 are fixedly mounted on the top outer wall of the chassis 4. The output shaft ends of the driving motors 6 penetrate the chassis 4 and are fixedly connected to the brush discs 5. The driving motors 6 drive the two brush discs 5 to rotate to clean the floor.
[0024] The bottom outer wall of the base frame 1 is rotatably connected to multiple connecting arms 2, and the top outer wall of the chassis 4 is fixedly connected to multiple fixing parts 3. The end of the connecting arm 2 away from the base frame 1 is hinged to the fixing part 3, and the chassis 4 is connected to the base frame 1 through the connecting arm 2 and the fixing part 3.
[0025] The implementation principle of the anti-collision device of the brush plate lifting structure of a ride-on floor scrubber in the embodiment of the present application is as follows: when in use, the electric push rod 8 is started, and the output shaft of the electric push rod 8 is extended and retracted to push and pull the chain 9 to move, and the chain 9 pulls or pushes the buffer assembly to drive the chassis 4 to rise and fall, and the chassis 4 can drive the two brush plates 5 to adjust the height. It is worth noting that when the chassis 4 is raised and lowered, the connecting arm 2 is driven to rotate through the fixing member 3, and the chassis 4 is connected to the base frame 1 through the cooperation of the connecting arm 2 and the fixing member 3;
[0026] After the height position of the chassis 4 is adjusted and fixed, through the buffer assembly, when the chassis 4 collides with the uneven ground, the impact force generated drives the chassis 4 to vibrate and move up and down. When the chassis 4 moves up, it pushes the U-shaped part 11 and the connecting block 12 to move up. At this time, the chain 9 is deformed, which can prevent the impact force from being suddenly transmitted to the electric push rod 8. When the chassis 4 moves down, it will pull the U-shaped part 11 to move the U-shaped part 11 down. The U-shaped part 11 and the connecting block 12 cooperate to squeeze the buffer spring 13, and the buffer spring 13 deforms to generate elastic force. The elastic force generated by the deformation of the buffer spring 13 is used to buffer the chassis 4, which effectively prevents the chassis 4 from being pulled down suddenly, causing structural damage to the electric push rod 8, and achieving an anti-collision effect.
