Description

Technical Field

[0001] This utility model relates to the field of floor scrubber base technology, specifically a base assembly for a floor scrubber. Background Technology

[0002] The base of a floor scrubber is an important component, serving to support and stabilize the entire device. The design of the base can affect the performance, stability, and operability of the floor scrubber.

[0003] Currently, floor scrubbers generally include a main unit, a drive mechanism, a balancing and steering mechanism, and a cleaning mechanism. The drive mechanism is used to drive the main unit to move, the balancing and steering mechanism is used to assist the drive mechanism in maintaining the balance of the main unit and to guide the main unit to turn, and the cleaning mechanism is used to store clean water, clean the floor, and collect wastewater. The cleaning mechanism includes a roller brush and a squeegee. In order to make the main unit more stable during movement and have a certain obstacle avoidance ability, springs are usually installed in the drive mechanism and the balancing and steering mechanism. The springs play a role in buffering and shock absorption. In addition, in order to achieve better cleaning results, the roller brush and the squeegee have a certain degree of elasticity, so that the surface of the roller brush and the edge of the squeegee always keep in close contact with the floor during the cleaning process.

[0004] However, after the floor scrubber completes its cleaning task, people usually place it directly on the ground or in a storage cabinet. In this way, the springs in the drive mechanism and balance steering mechanism, as well as the surface of the roller brush and the edge of the squeegee, are constantly compressed under the weight of the machine. Over time, the springs will fatigue and fail, affecting the stability and obstacle avoidance ability of the machine. The surface of the roller brush and the edge of the squeegee will deform, affecting the cleaning effect. In severe cases, it will cause the drive mechanism and balance steering mechanism to malfunction, greatly increasing the failure rate of the floor scrubber, shortening its service life, and reducing the user experience.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0017] Please see Figures 1-5 This utility model provides a technical solution: a base assembly for a floor scrubber, comprising: two side plates 1, a base plate 2 fixedly installed between the lower ends of the two side plates 1, a support seat 3 provided inside the side plates 1, the support seat 3 for placing the floor scrubber (the floor scrubber has been disclosed in patent publication number CN110037622B), one end of the support seat 3 is rotatably connected to the side plate 1, and both the front and rear ends of the lower side of one end of the support seat 3 are fixedly installed with rotating shafts, the rotating shafts are rotatably connected to the side plates 1, allowing the support seat 3 to rotate between the two side plates 1, one end of the support seat 3 is rotatably connected to a guide plate 4 via a hinge, facilitating the floor scrubber to enter the support seat 3 through the guide plate 4, and a support component is provided on the lower side of the other end of the support seat 3, the support component is used to diagonally support the support seat 3, so that the floor scrubber can be stably supported even when the support seat 3 is placed in a sloping position.

[0018] The supporting components include a slide plate 16 fixed to the upper end of the base plate 2. The slide plates 16 are two parallel pieces. The side walls of the two slide plates 16 are provided with grooves 17. A slider 18 is provided between the inner ends of the two slide plates 16. A guide block 24 is fixedly installed on the outer wall of the slider 18. The outer end of the guide block 24 is slidably inserted into the groove 17, so that the slider 18 can slide within the two slide plates 16.

[0019] A push rod 19 is rotatably connected to the other side wall of the slider 18. A top groove 9 is provided at the lower end of the receiving seat 3. The upper end of the push rod 19 can be inserted into the top groove 9 to lift and support one end of the receiving seat 3. A moving groove 20 is provided at the inner end of the slider 18. The moving groove 20 passes through the upper end and the left and right ends of the slider 18 respectively. Two moving plates 21 are slidably connected in the moving groove 20. The moving plates 21 are U-shaped. One end of the moving plate 21 is located at the upper end of the slider 18, and the other end is located at the side end of the slider 18. A fixed device is installed on the outer side of the side end. The anti-slip pad 22 and two movable plates 21 are evenly fixed between one side of the upper end of the slider 18. Several springs 23 are fixedly installed. When the springs 23 are in a compressed state, the anti-slip pad 22 and the slide plate 16 are in contact, fixing the slider 18. By pinching the upper end of the two movable plates 21 and pushing them inward, the movable plates 21 move inward by squeezing the springs 23 again, separating the anti-slip pad 22 and the slide plate 16, so that the slider 18 can slide. Adjusting the angle of the top rod 19 to lift the support seat 3 makes it easy to place the support seat 3 on the slope of different inclines.

[0020] When the support seat 3 is placed on a horizontal ground, the top rod 19 is located between the two sliding plates 16, the lower end of the support seat 3 is in contact with the upper end of the moving plate 21, and under the weight of the support seat 3 and other components on the support seat 3, the support seat 3 is horizontally located inside the side plate 1.

[0021] A lifting component is provided at the lower end of the receiving base 3. The lifting component is used to lift the floor scrubber on the receiving base 3. The lifting component includes a storage groove 5 opened on the receiving base 3. The cross-section of the storage groove 5 is inverted "convex". A top plate 14 is slidably arranged in the storage groove 5. A rubber pad 15 is fixedly installed at the upper end of the top plate 14. A top column 13 is fixedly installed at the lower end of the top plate 14. The lower end of the top column 13 extends out of the outside of the storage groove 5 and is fixedly installed with a connecting plate 12. An electric push rod 11 is fixedly installed on one side of the connecting plate 12. The other end of the electric push rod 11 is fixed to the bottom end of the receiving base 3. When the electric push rod 11 is started, it can push the top plate 14 and the rubber pad 15 out of the storage groove 5 and contact the edge of the chassis of the floor scrubber, avoiding the roller brush and scraper, and lift the floor scrubber.

[0022] A groove 6 is provided on the upper side of the other end of the receiving seat 3, and a controller 10 is fixedly installed on the lower end. The controller 10 is electrically connected to the pressure sensor 8 and the electric push rod 11. The groove 6 is used to place the walking wheels of the floor scrubber. An arc plate 7 is provided in the groove 6. The pressure sensor 8 is fixedly installed on the lower end of the arc plate 7. When the walking wheels of the floor scrubber are located in the groove 6, they will be located on the upper end of the arc plate 7 and exert pressure on the arc plate 7. The arc plate 7 transmits the pressure to the pressure sensor 8, and the pressure sensor 8 will send a signal to the controller 10. The controller 10 will activate the electric push rod 11 to lift the floor scrubber upward, so that the drive mechanism and balance steering mechanism of the floor scrubber can rest, and the roller brush and scraper can also have space to return to their original state. This ensures that the drive mechanism, balance steering mechanism, roller brush and scraper maintain efficient operation during the cleaning operation, thereby effectively solving the problem of fatigue and failure of the springs in the drive mechanism and balance steering mechanism caused by improper storage of the floor scrubber, as well as deformation of the surface of the roller brush and the edge of the scraper, and extending the service life of the floor scrubber.

[0023] In actual use, after the floor scrubber finishes scrubbing, it enters the receiving seat 3. When the rollers of the floor scrubber enter the groove 6, the floor scrubber moves into position within the receiving seat 3. The floor scrubber exerts pressure on the arc plate 7, which transmits the pressure to the pressure sensor 8. The pressure sensor 8 sends a signal to the controller 10, which then activates the electric push rod 11 to lift the floor scrubber upward, allowing the drive mechanism and balance steering mechanism of the floor scrubber to rest, and giving the roller brush and scraper space to return to their original positions.
