Description

Technical Field

[0001] This utility model relates to the field of floor scrubber protection technology, and in particular to a floor scrubber anti-collision structure. Background Technology

[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors while simultaneously drying wastewater and removing it from the site. It has advantages such as being environmentally friendly, energy-saving, and highly efficient. Floor scrubbers are generally classified as semi-automatic floor scrubbers, fully automatic floor scrubbers, walk-behind floor scrubbers, and ride-on floor scrubbers.

[0003] Patent publication number CN217338461U discloses an anti-collision structure for a floor scrubber, including an anti-collision mechanism. The floor scrubber is mounted on the rear outer surface of the anti-collision mechanism, and a lockable omnidirectional wheel is mounted on the lower outer surface of the floor scrubber. An installation mechanism is mounted on the upper outer surface of the anti-collision mechanism, and a push-pull handle is mounted on one side outer surface of the floor scrubber. This anti-collision mechanism effectively improves the anti-collision performance of the floor scrubber, preventing it from being easily damaged by collisions. When the floor scrubber is impacted, the second spring, pressure plate, elastic column, arc-shaped buffer plate, and buffer foam all deform, dissipating the impact force on the floor scrubber during deformation and preventing excessive impact. The installation mechanism makes it easier for people to install the anti-collision mechanism, effectively improving convenience and facilitating future replacement and maintenance.

[0004] The above devices provide protection for floor scrubbers by setting up buffer plates for collision protection. However, the above protection functions are relatively simple and lack the function of guiding and dissipating the impact force. This leads to the possibility that after a single collision, the floor scrubber may bounce back and impact again due to the elastic force. The corresponding anti-collision performance is poor. Furthermore, under multiple collisions, the buffer plate may be damaged and need to be replaced due to repeated collisions and friction with the collision surface, thereby increasing the operating cost. Therefore, a floor scrubber anti-collision structure is proposed to solve the above problems. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an anti-collision structure for a floor scrubber.

[0006] The anti-collision structure for a floor scrubber provided by this utility model adopts the following technical solution:

[0007] A floor scrubber anti-collision structure includes a floor scrubber body, and an anti-collision mechanism is provided on the outside of the floor scrubber body;

[0008] The anti-collision mechanism includes a protective frame disposed on the outside of the floor scrubber body. A slider is slidably connected to the outer wall of the floor scrubber body. A first spring is fixedly connected to one side of the slider and is also fixedly connected to the outer wall of the floor scrubber body. A positioning frame is fixedly connected to the slider. A mounting base is slidably connected inside the positioning frame. A second spring is fixedly connected to one side of the mounting base and is also fixedly connected to one side of the slider. A mounting plate is fixedly connected to the protective frame and extends into the mounting base, matching the mounting base. Mounting frames are slidably connected inside the protective frame and are arranged at equal intervals inside the protective frame. A spring is fixedly connected to one side of each mounting frame and is also fixedly connected inside the protective frame. A roller is rotatably connected inside the mounting frame and extends out of the mounting frame.

[0009] By adopting the above technical solution, when the floor scrubber is working, the protective frame installed on its exterior can provide effective protection for the outside of the floor scrubber. In the event of a collision, the roller will first come into contact with the collision surface. Upon contact, the elastic force of the spring and the second spring can buffer the impact force. During the impact, the roller can also roll along the direction of the impact force, causing the floor scrubber to turn. In this way, it can not only buffer the collision but also dissipate the force, greatly protecting the floor scrubber.

[0010] As a further optimization, two fixing plates are slidably connected to the inner side of the mounting plate, and both fixing plates extend out of the outer side of the mounting plate. Fixing grooves are provided on both sides of the mounting base, and a bidirectional threaded rod is rotatably connected inside the mounting plate.

[0011] By adopting the above technical solution, the thread directions at both ends of the bidirectional threaded rod are opposite.

[0012] As a further optimization, the fixing plate passes through the fixing groove and matches the fixing groove, and the bidirectional threaded rod passes through the two fixing plates in sequence and is connected to the fixing plates by threads.

[0013] By adopting the above technical solution, the bidirectional threaded rod can drive the two fixed plates to move towards or away from each other after rotation.

[0014] As a further optimization, a rotating plate is fixedly connected to the outside of the bidirectional threaded rod, and the rotating plate is located in the middle part of the bidirectional threaded rod.

[0015] By adopting the above technical solution, the rotation of the bidirectional threaded rod is controlled by a rotating plate.

[0016] As a further optimization, the anti-collision mechanism includes a warning component, which includes a rectangular plate. The rectangular plate is disposed on one side of the mounting base and is fixedly connected to the slider. A switch is fixedly connected to the rectangular plate. A support plate is fixedly connected to the top of the floor scrubber body. A motor is fixedly connected to the front side of the support plate. The motor is electrically connected to the switch. An impact block is fixedly connected to the top of the floor scrubber body.

[0017] By adopting the above technical solution, the motor starts to work after the switch is squeezed and collided.

[0018] As a further optimization, an impact block is slidably connected to one side wall of the support plate, the impact block is disposed on the top of the impacted block, and an extension plate is integrally formed on the impact block.

[0019] By adopting the above technical solution, the impact block emits an audible alarm after striking the impacted block.

[0020] As a further optimization, a round rod is rotatably connected to the inner side of the support plate, and a striking wheel is fixedly connected to the outside of the round rod. The motor is fixedly connected to one end of the round rod through an output shaft.

[0021] By adopting the above technical solution, the striking wheel rotates and strikes the impact block.

[0022] In summary, this utility model has the following beneficial technical effects:

[0023] 1. Through the design of the anti-collision mechanism, when the floor scrubber is working, the external protective frame can provide effective protection for the outside of the floor scrubber. In the event of a collision, the roller will first come into contact with the collision surface. At the moment of contact, the elastic force of the spring and the second spring can buffer the impact force. During the impact, the roller can also roll in the direction of the impact force, causing the floor scrubber to turn. In this way, it can not only buffer the collision but also dissipate the force, which greatly protects the floor scrubber.

[0024] 2. Through the design of the early warning component, when the mounting base moves due to a collision, the mounting base will touch the switch. After the switch is pressed, the motor will work. At this time, the striking wheel will rotate and strike the extension plate on the impact block, causing the impact block to rise to a high position. Due to gravity, it will move downward until it touches the impacted block. The two collide and make a sound. This repeated impact will serve as a collision alarm to the outside world, so that the staff can deal with it in time and further ensure the safety of the floor scrubber. Attached Figure Description

[0032] The following combination Figures 1 to 6 The present invention will be described in further detail below.

[0033] like Figures 1 to 6 As shown, this utility model discloses an anti-collision structure for a floor scrubber, including a floor scrubber body 1, an anti-collision mechanism 2 on the outside of the floor scrubber body 1, the anti-collision mechanism 2 including a protective frame 21, the protective frame 21 being disposed on the outside of the floor scrubber body 1, a slider 22 being slidably connected to the outer wall of the floor scrubber body 1, a first spring 23 being fixedly connected to one side of the slider 22, the first spring 23 being fixedly connected to the outer wall of the floor scrubber body 1, a positioning frame 24 being fixedly connected to the slider 22, a mounting base 25 being slidably connected inside the positioning frame 24, a second spring 26 being fixedly connected to one side of the mounting base 25, the second spring 26 being fixedly connected to one side of the slider 22, an mounting plate 27 being fixedly connected to the protective frame 21, the mounting plate 27 extending into the mounting base 25 and matching the mounting base 25, and mounting frames 28 being slidably connected inside the protective frame 21, the mounting frames 28 being arranged at equal intervals inside the protective frame 21;

[0034] A spring 29 is fixedly connected to one side of the mounting frame 28. The spring 29 is fixedly connected inside the protective frame 21. A roller 291 is rotatably connected inside the mounting frame 28. The roller 291 extends out of the mounting frame 28. When the floor scrubber body 1 is working, the protective frame 21 installed on its outside can provide effective protection for the outside of the floor scrubber body 1. If a collision occurs, the roller 291 will first contact the collision surface. When in contact, the elastic force of the spring 29 and the second spring 26 can buffer the impact force. During the impact, the roller 291 can also roll along the direction of the impact force. During the rolling process, the floor scrubber body 1 will turn. In this way, it can not only buffer the collision but also unload the force, which greatly protects the floor scrubber body 1.

[0035] Two fixing plates 292 are slidably connected to the inner side of the mounting plate 27. Both fixing plates 292 extend out of the outer side of the mounting plate 27. Fixing grooves 293 are provided on both sides of the mounting base 25. A bidirectional threaded rod 294 is rotatably connected inside the mounting plate 27. The threads at both ends of the bidirectional threaded rod 294 are opposite. The fixing plates 292 pass through the fixing grooves 293 and match the fixing grooves 293. The bidirectional threaded rod 294 passes through the two fixing plates 292 in sequence and is connected to the fixing plates 292 by threads. After the bidirectional threaded rod 294 rotates, it can drive the two fixing plates 292 to move towards each other or away from each other. A rotating plate 295 is fixedly connected to the outside of the bidirectional threaded rod 294. The rotating plate 295 is set in the middle part of the bidirectional threaded rod 294, and the rotation of the bidirectional threaded rod 294 is controlled by the rotating plate 295.

[0036] The anti-collision mechanism 2 includes a warning component, which includes a rectangular plate 296. The rectangular plate 296 is disposed on one side of the mounting base 25 and is fixedly connected to the slider 22. A switch 297 is fixedly connected to the rectangular plate 296. A support plate 298 is fixedly connected to the top of the floor scrubber body 1. A motor 299 is fixedly connected to the front side of the support plate 298. The motor 299 is electrically connected to the switch 297. An impact block 281 is fixedly connected to the top of the floor scrubber body 1. After the switch 297 is squeezed and collided, the motor 299 starts to work.

[0037] An impact block 282 is slidably connected to one side wall of the support plate 298. The impact block 282 is set on the top of the impact block 281. An extension plate 283 is integrally formed on the impact block 282. After the impact block 282 strikes the impact block 281, it emits an audible alarm. A round rod 284 is rotatably connected to the inner side of the support plate 298. A striking wheel 285 is fixedly connected to the outside of the round rod 284. A motor 299 is fixedly connected to one end of the round rod 284 through an output shaft. After the striking wheel 285 rotates, it strikes the impact block 282.

[0038] In actual operation, the device is first connected to the power supply. When the floor scrubber body 1 is working, the protective frame 21 provides outer collision protection. When a collision occurs, the outermost roller 291 contacts the collision surface. Due to the collision force, the roller 291 moves towards the floor scrubber body 1, causing the mounting frame 28 to move. As the mounting frame 28 moves, the elastic force of the spring 29 provides cushioning. Simultaneously, the collision force continues to be transmitted to the protective frame 21, causing the protective frame 21 to move the mounting plate 27. Mounting plate 27 drives mounting base 25 to move. During the movement of mounting base 25, it compresses second spring 26. At this time, the elastic force of second spring 26 can also buffer the impact force. If the direction of the collision force is relative to the movable direction of slider 22, then according to the above principle, slider 22 will also move and compress first spring 23 during sliding. The elastic force of first spring 23 can buffer the collision force in this direction. Based on the above steps, collision buffer protection can be properly provided for the floor scrubber body 1 during collision.

[0039] Based on the above collision protection, since the roller 291 first contacts the collision surface, the roller 291 will also roll during the contact process. Therefore, the roller 291 rolls along the direction of the impact force. During the rolling process, it causes the floor scrubber body 1 to turn. In this way, it can not only buffer the collision but also unload the force, avoiding secondary damage caused by the floor scrubber body 1 bouncing up and colliding again after a single collision. This greatly provides protection for the floor scrubber body 1.

[0040] When the mounting base 25 moves due to the above collision, the mounting base 25 will touch the switch 297. After the switch 297 is pressed, the motor 299 will work. After the motor 299 works, it will drive the round rod 284 to rotate. The round rod 284 will drive the striking wheel 285 to rotate. After the striking wheel 285 rotates, it will strike the extension plate 283 on the impact block 282. After the extension plate 283 is subjected to force, it will drive the impact block 282 to move upward. After the impact block 282 rises to a high position, it will move downward under the action of gravity until it touches the impact block 281. The two collide and make a sound. This repeated collision will serve as a collision alarm to the outside world, so that the staff can deal with it in time and further ensure the safety of the floor scrubber body 1.

[0041] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
