Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to a mounting bracket for roller brushes and an unmanned sweeper. Background Technology

[0002] With the rapid development of smart cities and autonomous driving technology, unmanned sweeping vehicles, as an important carrier of automated sanitation equipment, have demonstrated significant application value in scenarios such as municipal roads, industrial parks, and airports. Their core objective is to reduce labor costs, improve cleaning efficiency, and adapt to the needs of continuous operation in complex environments through unmanned operation.

[0003] In existing technologies, unmanned sweepers directly fix the roller brush and its drive motor to the vehicle frame, achieving the rotational sweeping function through transmission components (such as belts and gears). Simultaneously, the vehicle frame needs to reserve independent space to install trash cans or waste collection bins, and be equipped with a conveying device to transfer waste from the roller brush to the storage area. In this layout, the roller brush drive module and the waste storage system are physically separated, working together through mechanical connections or flow channels to form a basic functional chain of "sweeping-collection-storage".

[0004] However, since the roller brush needs to be in direct contact with the ground, it must occupy the longitudinal space at the bottom of the frame. Furthermore, the rigid connection of the drive motor and transmission components means that they must occupy a designated space in the frame. At the same time, storage devices such as trash cans also need to be independently arranged in the middle or rear of the frame, resulting in poor flexibility in the overall spatial layout of the frame and low space utilization. Utility Model Content

[0005] The purpose of this utility model is to provide a mounting bracket for roller brushes and an unmanned sweeping vehicle, solving the problem that in the prior art, the roller brushes and other structures in the unmanned sweeping vehicle all need to occupy specific space in the frame, resulting in poor flexibility in the layout of the space in the frame and low space utilization.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, this utility model provides a mounting bracket for a roller brush, which includes a main body. The main body is bent and extended, and side plates are provided on both sides of the main body. The side plates and the bottom wall of the main body enclose a first mounting space. The roller brush is located in the first mounting space and is rotatably connected to the side plates. The side plates and the top wall of the main body form a second mounting space. The side plates are used to install a drive mechanism for driving the roller brush to rotate, and the drive mechanism is located in the second mounting space.

[0008] Optionally, the main body includes:

[0040] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] like Figures 1 to 4 As shown, this utility model provides a mounting bracket for a roller brush and an unmanned sweeper.

[0042] The roller brush mounting bracket includes a main body 1. The main body 1 is bent and extended, and side plates 2 are provided on both sides of the main body 1. The side plates 2 and the bottom wall of the main body 1 enclose a first mounting space 11. The roller brush is located in the first mounting space 11 and is rotatably connected to the side plates 2. The side plates 2 and the top wall of the main body 1 form a second mounting space 12. The side plates 2 are used to install a drive mechanism that drives the roller brush to rotate. The drive mechanism is located in the second mounting space 12.

[0043] By enclosing a first mounting space 11 and a second mounting space 12 between the main body 1 and the side plate 2, the roller brush and the drive mechanism are respectively arranged in the first mounting space 11 and the second mounting space 12. This allows the roller brush and drive mechanism to be integrated and arranged between the main body 1 and the side plate 2, enabling flexible layout within the corresponding space according to the size of the roller brush and the composition of the drive assembly. Then, the roller brush mounting bracket is fixed to the bottom of the frame. Only space needs to be reserved at the bottom of the frame for the roller brush mounting bracket; the remaining space can be flexibly arranged for other structures as needed. Therefore, when using this roller brush mounting bracket, by integrating the drive mechanism and roller brush within the space enclosed by the main body 1 and the side plate 2, and then installing it at the bottom of the frame, the structure of the roller brush and drive mechanism has minimal impact on the spatial layout of the frame itself. This facilitates flexible use of the frame space and allows for flexible arrangement of structures such as trash cans on the frame.

[0044] In order to fix the main body 1 to the frame, the edge of the side plate 2 may optionally have a flap 21, and the flap 21 is provided with a plurality of mounting holes for installing fasteners at intervals.

[0045] Specifically, the top wall of the side plate 2 bends outward to form a flap 21. Multiple mounting holes are spaced along the length of the flap 21, and a fastener can be installed in each hole to secure the flap 21 to the frame. To facilitate adjustment of the main body 1's position, multiple connecting ears 22 are spaced apart on the flap 21. Each connecting ear 22 has a slotted hole for installing an adjustment component, which can be a bolt threaded to the frame or a hook that engages with the frame. During installation, the position of the main body 1 relative to the frame can be adjusted by changing the relative positions of the adjustment components within the adjustment holes, ensuring that all structures are in the optimal cleaning position and effectively improving cleaning efficiency.

[0046] Optionally, the main body 1 includes a first mounting plate 13 and a second mounting plate 14. The first mounting plate 13 extends along a first direction and is fixedly connected to two side plates 2 on both sides respectively; the second mounting plate 14 is disposed on one side of the first mounting plate 13 and extends along a second direction, which intersects with the first direction; wherein the first mounting plate 13, the second mounting plate 14 and the two side plates 2 enclose a first mounting space 11 and a second mounting space 12.

[0047] Specifically, the first direction can be horizontal, meaning the first mounting plate 13 extends horizontally, and the front side of the first mounting plate 13 bends downward to accommodate the first roller brush 4 in the roller brush. The second mounting plate 14 is located behind the first mounting plate 13, and the second direction can form an angle of 45° or 60° with the first direction, so that the second mounting plate 14 extends upward at an angle along the second direction. Both the first mounting plate 13 and the second mounting plate 14 are located between the two side plates 2, and the three can be fixed by welding or bolting, thereby enclosing the first mounting space 11 and the second mounting space 12.

[0048] Within the first installation space 11, a first roller brush 4 can be installed on the lower side of the first mounting plate 13. The curved portion on the front side of the first mounting plate 13 can effectively cover the first roller brush 4. The upward tilt of the second mounting plate 14 provides sufficient space for the installation of the second roller brush 5. The second roller brush 5 can move below the second mounting plate 14 and is connected to the side wall through a swing arm mechanism. The swing arm mechanism can adjust the height of the second roller brush 5.

[0049] Within the second mounting space 12, the drive mechanism includes a first drive assembly 6 and a second drive assembly 7. The first drive assembly 6 is connected to the first roller brush 4 to drive its rotation, and its drive element can be disposed on the inner wall of the side plate 2 and located within the second mounting space 12. The second drive assembly 7 is connected to the second roller brush 5 to drive its rotation, and its drive element is disposed on the inner wall of another side plate 2 and also located within the second mounting space 12. This allows the most space-consuming component of the drive mechanism to be built into the second mounting space 12, forming an overlapping layout with the roller brush, thereby effectively saving space.

[0050] Optionally, the side plate 2 is provided with a first mounting hole 23, a second mounting hole 24 and a plurality of third mounting holes 25 spaced apart. The first mounting hole 23 is used to install the drive mechanism, the second mounting hole 24 is used to install the swing arm assembly 8, and the third mounting hole 25 is used to install the roller brush. The first mounting hole 23 is located on the upper side of the side plate 2, the third mounting hole 25 is located on the lower side of the side plate 2, and the second mounting hole 24 is located between the first mounting hole 23 and the third mounting hole 25.

[0051] By pre-opening the first mounting hole 23, the second mounting hole 24, and multiple third mounting holes 25 on the side plate 2, and arranging the first mounting hole 23, the second mounting hole 24, and multiple third mounting holes 25 according to the first mounting space 11 and the second mounting space 12, the roller brush, the drive mechanism, and the swing arm assembly 8 can be reasonably arranged in the corresponding space, thereby improving the compactness between the various structures and the utilization rate of the corresponding space. It should be understood that the specific number and opening position of the mounting holes can be designed according to the actual size of the main body 1 and the size of the mounting space that can be formed, and are not limited to the layout method in the example above.

[0052] Optionally, the main body 1 also includes a third mounting plate 15 and a fourth mounting plate 16. The third mounting plate 15 is disposed on the side of the second mounting plate 14 away from the first mounting plate 13, and the third mounting plate 15 extends along a third direction and is used for fixed connection with the frame; the fourth mounting plate 16 is disposed below the third mounting plate 15 and forms a non-0° angle with the third mounting plate 15.

[0053] Specifically, the third direction can be parallel to or intersect with the first direction. In this embodiment, the third direction is parallel to the first direction, causing the third mounting plate 15 to extend horizontally, allowing it to adapt to the structure of the frame and form a fixed connection with it. A fourth mounting plate 16 is installed below the third mounting plate 15, extending at an upward angle. The specific angle of inclination can be designed according to the actual installation space and is not limited in this invention. The side of the fourth mounting plate 16 closest to the third mounting plate 15 bends upward and is fixedly connected to the side of the third mounting plate 15 away from the second mounting plate 14. The two ends of the other side of the fourth mounting plate 16 are fixedly connected to the two side plates 2 respectively, thereby improving the overall load-bearing strength of the third mounting plate 15 and ensuring that the overall strength of the main body 1 meets the requirements.

[0054] Optionally, the side wall of the third mounting plate 15 is provided with an extension plate 151, which is fixedly connected to the side plate 2.

[0055] Specifically, an extension plate 151 extending vertically is provided on the side wall of the third mounting plate 15. The two can be an integral structure or fixedly connected by welding or other methods. The side wall of the extension plate 151 can be fixedly connected to the side plate 2, and the fixing method can be welding rings, bonding, or bolting. The lower side of the extension plate 151 can be fixedly connected to the fourth mounting plate 16, and the shape of the extension plate 151 can be adapted to the inclined extension of the fourth mounting plate 16. By providing the extension plate 151, the third mounting plate 15, the fourth mounting plate 16, and the side plate 2 can be connected together to further improve the overall strength of the main body 1. Meanwhile, a connecting seat 152 for connecting with the frame is provided on the side of the extension plate 151. The connecting seat 152 has a plate-like structure, with its two sides bent and attached to the side of the extension plate 151. It can be fixed by means of adhesive or welding at the attachment point. A through hole can be opened in the middle of the connecting seat 152 to form a fixed connection with the frame by installing fasteners, thereby improving the connection strength between the main body 1 and the frame and ensuring the installation stability of the main body 1 on the frame.

[0056] Optionally, the third mounting plate 15 has a first opening 153 for connecting to the dust removal device, and the fourth mounting plate 16 has a second opening 161 for connecting to the garbage bin.

[0057] Specifically, the gap between the third mounting plate 15 and the fourth mounting plate 16 can form a channel for garbage flow. A dust removal device is installed on the upper side of the third mounting plate 15 to absorb dust. A first opening 153 is opened in the middle of the third mounting plate 15. The first opening 153 can be rectangular or circular and is connected to the dust removal device through a sealed pipe, thereby connecting the dust removal device to the aforementioned channel. A garbage bin for accommodating heavier garbage can be installed on the lower side of the fourth mounting plate 16. A second opening 161 is correspondingly opened on the fourth mounting plate 16, and the second opening 161 is connected to the opening of the garbage bin. The connecting area of ​​the second opening 161 is smaller than the opening area of ​​the garbage bin, thereby ensuring that garbage can accurately enter the garbage bin. The specific size of the first opening 153 and the second opening 161 can be designed according to the actual garbage cleaning efficiency, and this utility model does not limit it.

[0058] Optionally, the mounting bracket for the roller brush also includes a surround plate 3. The surround plate 3 is disposed below the side plate 2 and at least partially covers the side of the roller brush.

[0059] Specifically, the enclosure 3 is ring-shaped and can be formed by multiple plate-like structures or by bending a single plate-like structure. The enclosure 3 is arranged around the four sides of the roller brush, which can cover the sides of the roller brush, thereby forming a covering space at the roller brush. This ensures that the garbage swept by the roller brush is retained in this space, reducing the possibility of garbage being missed and thus improving the cleaning effect.

[0060] The unmanned sweeper includes a frame, a roller brush, a drive mechanism, and the aforementioned roller brush mounting bracket, which is mounted on the frame. The roller brush is rotatably connected to the second mounting space 12 of the roller brush mounting bracket. The drive mechanism is connected to the roller brush to drive the roller brush to rotate.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
