Description

Technical Field

[0001] The utility model relates to the technical field of sweepers, and in particular to a small vehicle-mounted electric side brush mechanism. Background Art

[0002] The vehicle-mounted side brush is an efficient cleaning tool designed specifically for cleaning the vehicle environment. It is widely used in various sanitation equipment such as road sweepers and road sweepers. The side brush usually uses a brush wire material with strong wear resistance and good elasticity, such as nylon, polypropylene or mixed fibers, to ensure that the garbage can be thoroughly cleaned during the cleaning process and the cleaning surface is protected from damage. Its main function is to sweep garbage around the road edge, wall corners, and manhole covers into the main brush cleaning area, thereby improving cleaning coverage and efficiency.

[0003] However, the height adjustment structure of existing small vehicle-mounted sweeping devices is mostly fixed or requires complex adjustment and fixing auxiliary operations, and the height of the sweeping brush cannot be quickly adjusted, resulting in a decrease in cleaning efficiency. Especially when cleaning uneven roads or facing different types of garbage, the height cannot be flexibly adjusted according to needs, which limits the practicality and adaptability of the sweeping equipment in multiple scenarios. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] Please refer to Figures 1-2An embodiment of the present utility model provides a small vehicle-mounted electric side brush mechanism, comprising: a motor 1 and a sweeping brush 2.

[0020] Among them, such as Figure 1 、 Figure 2 and Figure 4 As shown, the rotating shaft of the motor 1 is fixedly connected to the sweeping brush 2, the outer wall of the motor 1 is symmetrically hinged with the first connecting rod 3 and the second connecting rod 4, the ends of the first connecting rod 3 and the second connecting rod 4 are hinged with the connecting plate 7 through the rotating shaft 5, the outer wall of the first connecting rod 3 is hinged with a U-shaped block 10, the outer wall of the second connecting rod 4 is hinged with a pull rod 11, the U-shaped block 10 is hinged to the inner wall of the pull rod 11 through a crank 17, and the two ends of the rotating shaft 5 located at the end of the second connecting rod 4 are fixedly connected with a fixed plate 16, and the fixed plate 16 is fixedly connected with a U-shaped baffle 9.

[0021] When in use, the first connecting rod 3 and the second connecting rod 4 drive the sweeping brush 2 to flexibly adjust the height by lifting the pull rod 11. When the operator pulls up the pull rod 11, the pull rod 11 drives the U-shaped block 10 to lift or lower through the crank 17. When the pull rod 11 is pulled and moved to one side of the U-shaped baffle 9, one side of the U-shaped block 10 will abut against the outer wall of the U-shaped baffle 9, limiting the sweeping brush 2 from further descending, thereby fixing the position of the sweeping brush 2 after lifting. When the pull rod 11 is pulled up again and moved downward to the side away from the U-shaped baffle 9, the U-shaped block 10 is lifted and releases its effect on the U-shaped baffle 9 through its position change, so that the sweeping brush 2 descends to the working position under the linkage action of the two connecting rods.

[0022] Furthermore, the inner wall of the bottom of the connecting plate 7 is fixedly connected to a limiting rod 15 , so that when the second connecting rod 4 descends to contact with the limiting rod 15 , it can be prevented from further descending.

[0023] In this embodiment, Figures 1-4 As shown, the top of the U-shaped block 10 is fixedly connected to the first spring 12, one end of the first spring 12 is fixedly connected to the top of the connecting plate 7, the outer wall of the U-shaped baffle 9 is fixedly connected to the second spring 13, one end of the second spring 13 is fixedly connected to the rotating shaft 5 at the end of the first connecting rod 3, when the operator pulls up the pull rod 11, the pull rod 11 drives the U-shaped block 10 to move through the crank 17, and at the same time the first spring 12 and the second spring 13 are stretched and deformed. When the operator releases the pull rod 11, the first spring 12 can pull the crank 17 to reset, and the second spring 13 can pull the U-shaped baffle 9 to reset.

[0024] like Figure 1 and Figure 2As shown, a fan-shaped plate 14 is fixedly connected to the bottom of the motor 1, and a bent plate 6 is installed on the fan-shaped plate 14. The bent plate 6 is provided with a through hole. When the sweeping brush 2 needs to introduce an external water source for flushing and cleaning, the external pipeline can be passed through the through hole on the bent plate 6, and the fixed position of the fan-shaped plate 14 and the bent plate 6 is used to support and limit the position of the pipeline.

[0025] Specifically, a side plate 8 is welded to one side of the connecting plate 7, and the side plate 8 can be fixedly connected to the bottom of both sides of the electric tricycle with the help of fixing parts.

[0026] According to the above technical solution, the working steps of this solution are summarized and sorted out: when in use, the sweeping brush 2 can flexibly adjust its height through the symmetrical hinge of the first connecting rod 3 and the second connecting rod 4. When the operator pulls up the pull rod 11, the pull rod 11 drives the U-shaped block 10 to lift or lower through the crank 17. When the pull rod 11 is pulled and moved to one side of the U-shaped baffle 9, one side of the U-shaped block 10 will abut against the outer wall of the U-shaped baffle 9, limiting the sweeping brush 2 from further descending, thereby fixing the position of the sweeping brush 2 after it is lifted.

[0027] When the pull rod 11 is pulled up again and moves downward to the side away from the U-shaped baffle 9, the U-shaped block 10 is lifted and releases the effect on the U-shaped baffle 9 through its position change, so that the sweeping brush 2 drops to the working position under the action of the two connecting rods. At this time, the U-shaped block 10 can drop and press on the outer wall of the U-shaped baffle 9, fixing the position of the sweeping brush 2 after it drops, so that the height adjustment of the sweeping brush 2 can be completed by simple manual operation. The entire mechanism is compactly designed and is suitable for installation and use on small electric tricycles.

[0028] Any portion not described in the present invention is the same as the prior art or can be implemented using the prior art. Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
