DETAILED DESCRIPTION

[0028] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1

[0030] The existing floor scrubber brush disc mainly realizes the structure of the brush disc by fixing it with the mounting plate. However, this fixed connection method is difficult to meet the collision requirements encountered by the floor scrubber during use. When the brush disc encounters a collision during the cleaning process, due to the fixed connection with the mounting plate, the brush disc cannot flexibly adjust the angle, resulting in damage to the brush disc or failure to work properly. The existing technology lacks an effective adjustment mechanism to deal with the collision of the brush disc. Therefore, it is necessary to explore a structure that can effectively buffer the collision and assist the brush disc to reset. Please refer to Figure 1-Figure 6 The present embodiment provides a floor scrubber brush disc collision reset structure, including a mounting plate 1 and a brush disc 2 arranged at the bottom of the mounting plate 1. The floor scrubber brush disc 2 is mounted at the bottom of the mounting plate 1, allowing the brush disc 2 to deflect to a certain extent during a collision and automatically reset after the collision, so as to protect the machine and increase its service life.

[0031] refer to Figure 1 As shown, the structure of the existing floor scrubber brush disc 2 is mainly realized by a fixed connection with the mounting plate 1. However, this fixed connection method is difficult to meet the collision requirements encountered by the floor scrubber during use. When the brush disc 2 encounters a collision during the cleaning process, due to the fixed connection with the mounting plate 1, the brush disc 2 cannot flexibly adjust the angle, resulting in damage to the brush disc 2 or failure to work normally. In order to effectively reduce the impact force generated by the collision and assist the brush disc 2 in resetting, and improve the safety and reliability of the floor scrubber, the following settings are made. The mounting plate 1 is provided with an adjustment mechanism 3 that flexibly adjusts the angle of the brush disc 2 when it encounters a collision and assists in resetting it after the collision. The adjustment mechanism 3 includes a rotating shaft 31 and a sliding rod 32 fixed on the brush disc 2. The rotating shaft 31 is rotatably connected to the inside of the mounting plate 1. The mounting plate 1 is provided with an arc groove 35. The inner wall of the arc groove 35 is bonded and fixed with a plush rubber plate 33, and the plush rubber plate 33 is a plate-like structure with flocking on the upper surface of a rubber material. The slide rod 32 is slidably sleeved inside the arc groove 35, and a top sealing plate 34 is fixedly connected to the top of the slide rod 32. The diameter of the top sealing plate 34 is larger than the diameter of the slide rod 32, and is used to eliminate the impact force before the slide rod 32 contacts the outermost side of the arc groove 35. Two return springs 36 are symmetrically fixedly connected to the brush disc 2, and the ends of the two return springs 36 away from the brush disc 2 are fixedly connected to the mounting plate 1.

[0032] In this embodiment, the adjustment mechanism 3 arranged on the mounting plate 1 is intended to effectively enhance the collision protection performance and safety of the floor scrubber during use. By fixing the rotating shaft 31 and the slide bar 32 on the brush disc 2, and opening an arc groove 35 in the mounting plate 1 and bonding the plush rubber sheet 33, not only a buffered movement path is provided for the slide bar 32, but also a layer of rubber flocking buffering protection is provided for the friction between the slide bar 32 and the arc groove 35, effectively avoiding possible wear or damage to the slide bar 32 during the left and right movement, thereby extending the service life of the product. At the same time, the rubber material and flocking surface of the plush rubber sheet 33 provide an anti-slip and wear-resistant effect for the rotation process of the brush disc 2, and combined with the stability of the entire device, it provides strong support for the safe operation of the floor scrubber.

[0033] Furthermore, when the floor scrubber encounters a collision during use, the brush disc 2 can rotate itself with the aid of the rotating shaft 31, which not only avoids impact damage caused by the fixed connection, but also through the cooperation of the two reset springs 36, one reset spring 36 is stretched and the other reset spring 36 is compressed to control the rotation amplitude of the brush disc 2, thereby reducing the impact of the mechanical force caused by the collision on the overall structure. In addition, the rotation of the brush disc 2 is effectively limited by the sliding of the slide bar 32 in the arc groove 35, which not only protects the brush disc 2 from excessive damage, but also ensures that the entire floor scrubber can be quickly and safely reset when facing a collision, thereby improving the working reliability and safety of the floor scrubber in actual application scenarios.

[0034] Example 2

[0035] Based on Example 1, Figure 3-Figure 5 As shown, a protective mechanism 37 is arranged on the mounting plate 1 to reduce the impact force of the slide bar 32 on the inner wall of the arc groove 35 when sliding left and right. The protective mechanism 37 includes a mounting ring 372 fixed on the mounting plate 1. The inner sliding sleeve of the mounting ring 372 is provided with a force rod 373. The interior of the mounting ring 372 is provided with a limiting component for making the force rod 373 slide along its inner wall in a directional manner. The limiting component includes an arc groove opened on the inner wall of the mounting ring 372. The outer wall of the force rod 373 is fixedly connected with an arc slider. The arc slider slides left and right along the length direction of the arc groove, and the force rod 373 is away from the mounting ring 372. One end of the force rod 373 is fixedly connected to the touch plate 371, and the end of the force rod 373 away from the touch plate 371 is provided with a buffer component for eliminating the impact force received by the touch plate 371. The buffer component includes an extension rod 375 fixed to the end of the force rod 373 away from the touch plate 371, and the outer wall of the extension rod 375 is sleeved with a buffer spring 374, and the two ends of the buffer spring 374 are respectively fixedly connected to the force rod 373 and the mounting ring 372, and a damper 376 is provided at the end of the extension rod 375 away from the touch plate 371, and the two ends of the damper 376 are respectively fixedly connected to the extension rod 375 and the mounting ring 372.

[0036] In this embodiment, the protection mechanism 37 provided on the mounting plate 1 is intended to effectively reduce the impact force of the slide bar 32 on the inner wall of the arc groove 35 when sliding left and right, thereby ensuring the safety and stability of the equipment operation. The core of the protection mechanism 37 is the mounting ring 372 and the force rod 373 slidably sleeved therein, which achieves the goal of eliminating the impact force generated during the sliding process through precise mechanical connection.

[0037] Furthermore, the clever introduction of the arc-shaped slider allows the force rod 373 to slide smoothly along the limited track, and the reasonable configuration of the touch plate 371 directly undertakes the external force transmission. When the slide bar 32 approaches the edges of the inner wall of the arc groove 35, the touch plate 371 is the first to receive the impact, pushing the force rod 373 to retract toward the mounting ring 372. This process not only realizes the transmission of force, but more importantly, through the synergy of the buffer component closely combined with it, a strong protective barrier is formed. The close cooperation of the buffer spring 374 and the damper 376 not only reduces the peak impact force, but also cleverly absorbs and buffers most of the energy before the slide bar 32 touches the two ends of the arc groove 35, avoiding damage caused by direct impact.

[0038] Example 3

[0039] Based on Example 2, Figure 4-Figure 6 The mounting plate 1 is provided with a stabilizing mechanism 4 for centering and preventing the brush plate 2 from swinging after it is reset. The stabilizing mechanism 4 includes a connecting plate 41 fixed on the top sealing plate 34. The inner part of the connecting plate 41 away from the end of the top sealing plate 34 is fixedly connected with a movable shaft 42. The movable shaft 42 rotates on the mounting ring 372. A clamping plate 48 is fixedly connected to the connecting plate 41. A semicircular clamping groove 49 is provided on the clamping plate 48. A rounded clamping rod 47 is provided in the semicircular clamping groove 49. A frame plate 43 is fixedly connected to the mounting plate 1. A push rod 47 is provided under the frame plate 43 to push the rounded clamping rod 47 to The semicircular slot 49 is connected and detachable power assembly, the power assembly includes a cylindrical rod 44 fixed under the frame plate 43, the top end of the rounded corner clamping rod 47 is fixedly connected with a circular plate 46, the circular plate 46 is slidably sleeved inside the cylindrical rod 44, the rounded corner clamping rod 47 is fixed under the circular plate 46, and a spring 45 is arranged inside the cylindrical rod 44. The reset force provided by the two reset springs 36 for the brush plate 2 is smaller than the clamping force provided by the spring 45 for the rounded corner clamping rod 47 to be clamped into the semicircular slot 49, and the two ends of the spring 45 are fixedly connected to the cylindrical rod 44 and the circular plate 46 respectively.

[0040] In this embodiment, the disc stabilizing mechanism 4 arranged on the mounting plate 1 is intended to effectively reduce the swing amplitude of the brush disc 2 after resetting, and enhance the accuracy and stability of the resetting process of the brush disc 2. A connecting plate 41 is arranged on the top sealing plate 34, and a movable shaft 42 is fixedly connected thereto, so that the movable shaft 42 can rotate freely on the mounting ring 372. At the same time, with the assistance of a clamping plate 48 and a semicircular clamping groove 49 arranged on the connecting plate 41, and the ingenious cooperation of the rounded clamping rod 47 and the power assembly, the stable resetting of the brush disc 2 is effectively ensured.

[0041] Furthermore, when the brush disc 2 needs to be reset due to collision or other reasons during operation, the reset spring 36 will drive the brush disc 2 to return to the initial position. At this time, the circular plate 46 including the top surface of the rounded corner clamping rod 47, under the power brought by the harmonic carrier, through the elastic recovery effect of the spring 45 inside the columnar rod 44, the rounded corner clamping rod 47 enters and is clamped into the semicircular clamping groove 49, thereby locking the position of the connecting plate 41. As a result of this design, the brush disc 2 achieves a neutral and stable recovery from collision to reset.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
