Description

Technical Field

[0001] This application relates to the technical field of floor scrubbers, and in particular to a structure for a brush cover assembly with a lift-up and cushioning mechanism. Background Technology

[0002] Among floor cleaning equipment, floor scrubbers are widely used in large areas such as shopping malls, factories, and office buildings due to their high-efficiency cleaning capabilities. Their core cleaning component is the brush disc at the bottom. During operation, the brush disc rotates at high speed, generating friction with the floor, and working with cleaning agents to remove and sweep away stains. The brush disc cover, as a supporting structure, not only collects wastewater and prevents stains from splashing during cleaning, but also lifts the brush disc off the ground when the machine is not in use, avoiding unnecessary wear caused by continuous contact between the brush disc and the floor.

[0003] However, the brush cover lifting mechanism of existing floor scrubbers generally adopts a rigid connection design—that is, the brush cover is directly connected to the machine body through a rigid bracket, metal connecting rod, or fixed pin, and the lifting action is achieved by the force of the drive device (such as hydraulic rod or motor). Although this connection method can ensure the stability of the lifting process, it has significant defects in actual operation: when the brush cover completes the lifting and reaches the preset position, due to the lack of buffering and adjustment capability of the rigid connection, the connection part between the brush cover and the machine body will experience a momentary rigid impact.

[0004] Such impacts not only generate harsh noise and affect the working environment, but more importantly, repeated impacts over a long period can cause cumulative damage to the connecting structure. Welds in rigid connectors may crack due to vibration, metal parts may gradually experience fatigue deformation, and even the brush cover may shift in position. Once the structure is damaged, it can affect the lifting accuracy of the brush cover, leading to splashing wastewater or uneven contact between the brush and the ground during cleaning; in severe cases, it can cause the brush cover to detach due to connection failure, directly affecting the normal operation of the floor scrubber, significantly shortening the equipment's lifespan, and increasing maintenance costs. Therefore, to solve the above problems, this application provides a cushioned lifting structure for the brush cover assembly. Utility Model Content

[0005] To address the aforementioned issues, this application provides a structure for lifting and cushioning the brush cover assembly.

[0006] This application provides a brush disc cover assembly with a lifting and buffering structure, including a brush disc cover on which a brush disc is installed, a motor on which the brush disc is driven, a buffering mechanism above the middle position of the brush disc cover, the buffering mechanism including a lifting component that drives the brush disc cover to move vertically, and an elastic connector for lifting and buffering above the brush disc cover, with a soft connection between the elastic connector and the lifting component.

[0007] By setting a buffer mechanism above the brush cover, a connecting plate and a buffer rod that slide and fit together are set above the brush cover, and a spring for buffering is also set between the two. The top of the buffer rod is softly connected to the electric push rod through a chain. In this way, a certain degree of buffering effect can be achieved under the action of the spring when the electric push rod drives the brush cover to move up and down.

[0008] Preferably, the elastic connector includes a connecting plate fixed to the brush cover, and the connecting plate has an internal movable space in which a buffer rod that passes through the connecting plate is slidably connected.

[0009] Preferably, a support plate is welded to the bottom end of the buffer rod, and a spring is provided between the support plate and the connecting plate, the spring applying a force to separate the support plate and the connecting plate.

[0010] Preferably, the lifting assembly is an electric push rod, which is installed inside the machine body via a mounting bracket.

[0011] Preferably, the output end of the electric push rod is flexibly connected via a chain and a buffer rod.

[0012] Preferably, the chain and the buffer bar are connected by a D-type shackle.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] By setting a buffer mechanism above the brush cover, a connecting plate and a buffer rod that slide and fit together are set above the brush cover, and a spring for buffering is also set between the two. The top of the buffer rod is softly connected to the electric push rod through a chain. In this way, a certain degree of buffering effect can be achieved under the action of the spring when the electric push rod drives the brush cover to move up and down. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1 - Figure 2 This application will be described in further detail.

[0019] Example 1:

[0020] A brush shroud assembly with a cushioned lifting structure, as shown in the reference. Figure 1 - Figure 2 It includes a brush cover 9 on which a brush disc is installed, a motor 4 on which the brush disc 10 is driven, a buffer mechanism above the middle position of the brush cover 9, the buffer mechanism including a lifting component that drives the brush cover 9 to move vertically, and an elastic connector for lifting and buffering above the brush cover 9, and a soft connection between the elastic connector and the lifting component.

[0021] By setting a buffer mechanism above the brush cover 9, a connecting plate 8 and a buffer rod 6 that slide and fit together are set above the brush cover 9, and a spring 7 for buffering is also set between the two. The top of the buffer rod 6 is softly connected to the electric push rod 2 through the chain 3, so that a certain degree of buffering effect can be achieved under the action of the spring 7 during the process of the electric push rod 2 driving the brush cover 9 to move up and down.

[0022] The elastic connector includes a connecting plate 8 fixed on the brush cover 9. The connecting plate 8 has an internal movable space. A buffer rod 6 is slidably connected through the connecting plate 8 within the movable space. The connecting plate 8 is configured as an n-shaped structure as shown in the figure. The buffer rod 6 is slidably connected at its center position. In the initial state, 1 / 3 of the buffer rod 6 is located outside the connecting plate 8, and 2 / 3 is located inside the movable space of the connecting plate 8.

[0023] A support plate 61 is welded to the bottom end of the buffer rod 6. A spring 7 is installed between the support plate 61 and the connecting plate 8. The spring 7 applies a force to separate the support plate 61 and the connecting plate 8. The diameter of the support plate 61 is larger than the outer diameter of the spring 7. The function of the spring 7 is to provide a certain buffer during the lifting and releasing process, thereby improving the stability of the brush cover 9.

[0024] The lifting assembly is an electric push rod 2, which is mounted inside the machine body via a mounting bracket 1. The output end of the electric push rod 2 is flexibly connected to a chain 3 and a buffer rod 6. The chain 3 and the buffer rod 6 are connected by a D-type shackle 5.

[0025] When brush disc 10 needs to be lifted, the electric push rod 2 retracts, causing the lower buffer rod 6 to move upward via the chain 3 and D-shaped shackle 5. The support plate 61 at the bottom of the buffer rod 6 first compresses the spring 7. When the spring 7 is compressed to its minimum limit, the buffer rod 6, along with the connecting plate, moves upward synchronously, causing the brush disc cover 9 to move upward synchronously, ultimately lifting the brush disc 10 off the ground. When lowering the brush disc 10, the electric push rod 2 extends, causing the chain 3 to move downward. The brush disc 10 will then contact the ground first, and subsequently, under the action of the spring, the buffer rod 6 returns to its original position. This achieves a buffering effect for both lifting and lowering states.

[0026] The foregoing description, with reference to preferred embodiments, provides an exemplary embodiment of a brush cover assembly with a liftable and buffered structure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
