Technical Field
[0001] This utility model relates to the field of cleaning robots, specifically to a lightweight cleaning transport vehicle structure. Background Technology
[0002] With the rapid development of technology, the demand for automation and intelligence in both industrial and domestic settings continues to rise, giving rise to and significantly advancing robotics technology. In the industrial sector, digital and intelligent transformation is an inevitable trend, and industrial cleaning robots, as key carriers of emerging technologies, can effectively handle high-intensity cleaning and transportation tasks. In the domestic setting, as people's living standards improve, automated home cleaning robots, as powerful assistants that liberate manpower and enhance quality of life, are gradually entering thousands of households.
[0003] Existing industrial cleaning robots are mainly semi-automatic, such as those disclosed in Chinese patents with publication numbers CN221308097U and CN213282757U. These robots require manual driving, have a low degree of automation, and are generally large and heavy, making them unsuitable for use in narrow workshop aisles and small workstations. Their high price also hinders their widespread adoption. Most existing home cleaning robots rely on sensors and cameras to achieve autonomous movement within the room. However, these robots can only handle small debris such as dust and cannot clean or transport regular or irregularly shaped debris, as exemplified by the sweeping robot disclosed in Chinese patent CN222737802U. Utility Model Content
[0004] The purpose of this utility model is to provide a lightweight cleaning and transfer vehicle structure that can clean and transfer waste. This cleaning and transfer vehicle has a simple structure, is lightweight, moves flexibly, has a wide range of applications, and is low in cost.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a lightweight cleaning transfer vehicle structure, including a lightweight hopper, a throughput mechanism, a traveling mechanism, and a control device; the lightweight hopper is a semi-enclosed hopper composed of multiple hollow plates; the throughput mechanism includes several roller brushes and roller brush drive motors, and can adjust the working height; the several roller brushes are arranged front and rear in the lower part of the lightweight hopper and driven by the roller brush drive motors; the traveling wheels of the traveling mechanism are arranged at the bottom of the lightweight hopper and driven by the traveling drive motors; the control device is electrically connected to the roller brush drive motors and the traveling drive motors respectively to control the operation of the throughput mechanism and the traveling mechanism.
[0006] Furthermore, the lightweight hopper is composed of multiple thin, perforated panels, including a top panel, two bottom panels, two inner side panels, and four side panels (front, rear, left, and right). The four side panels are located at the front, rear, left, and right sides and are connected sequentially to form a rectangular frame. The front and rear side panels are U-shaped structures to allow waste to enter and exit, while the left and right side panels are used to install the roller brush drive motor. The top panel is connected to the top of the rectangular frame. The two bottom panels are connected to the left and right sides below the rectangular frame and are used to install the travel drive motor. The two inner side panels are vertically arranged parallel to each other along the front-rear direction on the left and right sides of the rectangular frame, and the roller brushes on the front and rear sides and the waste they collect are located in the receiving channel formed between the two inner side panels.
[0007] Furthermore, adjustable roller brush mounting holes are vertically provided along the left and right side plates to adjust the mounting height of the roller brush drive motor.
[0008] Furthermore, the lightweight compartment also includes two hardware mounting plates and a camera mounting bracket; the two hardware mounting plates are horizontally arranged on the front and rear sides of the rectangular frame, and their left and right sides are respectively fixedly connected to two inner side plates for installing relevant hardware equipment that constitutes the control device; the front hardware mounting plate is located between the front and rear roller brushes, forming a waste-receiving space with the two inner side plates; the camera mounting bracket is fixedly connected to the front end of the top plate or the upper end of the front side plate for installing a camera module.
[0009] Furthermore, the throughput mechanism includes two front roller brushes, one rear roller brush, two roller brush drive motors, and two bearing seats. The two front roller brushes are located on the lower front side of the lightweight hopper and have a certain ground clearance. The two front roller brushes are arranged side by side and coaxially connected. One end of the connecting shaft of the two front roller brushes is rotatably connected to a first bearing seat installed on one side of the lightweight hopper, and the other end is connected to a first roller brush drive motor installed on the other side of the lightweight hopper via a coupling, so as to be driven to rotate. The rear roller brush is located on the lower rear side of the lightweight hopper and has a certain ground clearance.

[0014] Furthermore, the driving motor is a 2006 motor, and the driving motor is mounted on the base plate via a motor mounting bracket.
[0015] Furthermore, the control device includes a main control board and a power supply module; the main control board is electrically connected to the roller brush drive motor and the travel drive motor respectively; the main control board is also wirelessly connected to the remote control device; the power supply module supplies power to each electrical device including the roller brush drive motor and the travel drive motor respectively; the main control board and the power supply module are respectively mounted on two hardware mounting plates of the lightweight compartment.
[0016] Furthermore, it also includes a camera module, which is installed on the upper front side of the lightweight compartment and electrically connected to the control device located inside the lightweight compartment. The camera module uses a MaixCAM camera to acquire images of the front of the cleaning transfer vehicle, then identifies whether there are objects in front of it from the images and determines whether the objects are waste, and then sends the relevant signals to the control device.
[0017] Compared with existing technologies, this utility model has the following advantages: Addressing the problems of existing industrial cleaning robots (requiring manual operation, large size, heavy weight, and high price) and household cleaning robots (inability to handle waste of various shapes), this utility model proposes a lightweight cleaning transfer vehicle structure.

[0027] like Figure 1-5As shown, this embodiment provides a lightweight cleaning transfer vehicle structure, including a lightweight compartment, a throughput mechanism, a traveling mechanism, and a control device. The lightweight compartment is a semi-enclosed compartment composed of multiple perforated plates. The throughput mechanism includes several roller brushes and roller brush drive motors 9, and its working height is adjustable. The roller brushes are arranged front and rear in the lower part of the lightweight compartment and driven by the roller brush drive motors 9. The traveling wheels 4 of the traveling mechanism are located at the bottom of the lightweight compartment and driven by the traveling drive motors 5. The control device is electrically connected to the roller brush drive motors 9 and the traveling drive motors 5 to control the operation of the throughput mechanism and the traveling mechanism.
[0028] The lightweight compartment is composed of multiple thin, perforated panels, including a top panel 103, two bottom panels 105, two inner side panels 106, and four side panels (front side panel 101, rear side panel 104, left side panel, and right side panel 102). The four side panels are positioned at the front, rear, left, and right sides and are connected sequentially to form a rectangular frame. The front side panel 101 and rear side panel 104 have an inverted U-shaped structure to allow waste to enter and exit. The left and right side panels 102 are used to install the roller brush drive motor 9. The top panel 103 is connected to the top of the rectangular frame; the two bottom panels 105 are connected to the lower left and right sides of the rectangular frame and are used to install the travel drive motor 5. The side panels are designed with parallelograms, regular hexagons, triangles, circles, and other perforations, which helps achieve the lightweight goal. The top panel 103 also has numerous perforations, which helps achieve the lightweight goal. The two inner side plates 106 are vertically arranged parallel to each other in the front-to-back direction on the left and right sides of the rectangular frame, forming a rectangular receiving channel. The front and rear roller brushes and the waste they collect are located in the receiving channel formed between the two inner side plates 106, and the front roller brush is close to the front side plate and is in a semi-exposed state.
[0029] To adjust the working height of the throughput mechanism, adjustable roller brush mounting holes 2 are vertically provided along the upper edge of the left and right side plates 102 for adjusting the installation height of the roller brush drive motor 9. In this embodiment, the adjustable roller brush mounting holes 2 are 11 vertically arranged circular hollows, which can be adjusted to 11 levels according to the different shapes, sizes, and hardness of waste in industrial environments or household locations, greatly expanding the application scenarios and cleaning objects of this intelligent cleaning vehicle.
[0030] The lightweight compartment also includes two hardware mounting plates 6 and 7 and a camera mounting bracket 301. The two hardware mounting plates 6 and 7 are horizontally arranged on the front and rear sides of the rectangular frame, and their left and right sides are respectively fixedly connected to two inner side plates 106 for mounting the relevant hardware equipment that makes up the control device; the front hardware mounting plate 7 is located between the front and rear roller brushes, forming a waste-receiving space with the two inner side plates 106; the camera mounting bracket 301 is fixedly connected to the front end of the top plate 103 for mounting the camera module 3.
[0031] The throughput mechanism includes two front roller brushes 801, one rear roller brush 802, two roller brush drive motors 9, and two bearing seats 11. The two front roller brushes 801 are located on the lower front side of the lightweight chamber and have a certain ground clearance. The two front roller brushes 801 are arranged side by side and coaxially connected. One end of the connecting shaft of the two front roller brushes 801 is rotatably connected to a first bearing seat (fixed in the hollow of the inner side plate 106) installed on one side of the lightweight chamber, and the other end is connected to a first roller brush drive motor installed on the other side of the lightweight chamber through a coupling 901, so as to be driven to rotate. The rear roller brush 802 is located on the lower rear side of the lightweight chamber and has a certain ground clearance. One end of the connecting shaft of the rear roller brush 802 is rotatably connected to a second bearing seat (fixed in the hollow of the inner side plate 106) installed on one side of the lightweight chamber, and the other end is connected to a second roller brush drive motor installed on the other side of the lightweight chamber through a coupling 901, so as to be driven to rotate.
[0032] The control device uses two roller brush drive motors 9 to control the forward rotation of the front roller brush 801 and the reverse rotation of the rear roller brush 802, respectively. The forward rotation of the front roller brush 801 draws waste into the receiving space between the front and rear roller brushes 802, while the reverse rotation of the rear roller brush 802 prevents waste from leaving the receiving space during the movement of the cleaning transport vehicle. When the cleaning transport vehicle reaches the target location, it controls the front and rear roller brushes 801 and 802 to rotate simultaneously in either the forward or reverse direction to discharge the waste. In this embodiment, the roller brush drive motors 9 are KV2650 motors.
[0033] The traveling mechanism includes two bullseye wheels 10, two polyurethane traveling wheels 4, and two traveling drive motors 3. The two bullseye wheels 10 are mounted on the bottom plates 105 on the left and right sides of the lower part of the lightweight hopper. The two traveling wheels 4 are located on the lower left and right sides of the lightweight hopper and are respectively connected to the two traveling drive motors 3 mounted on the bottom plates 105 on the left and right sides, so that they are driven to rotate by the corresponding traveling drive motors 3. The two traveling drive motors 3 can realize the turning, forward or backward movement of the cleaning transfer vehicle by differential rotation or rotation at the same speed, combined with the operation of the bullseye wheels 10. In this embodiment, the traveling drive motors 3 are 2006 motors, and the traveling drive motors 3 are mounted on the bottom plate 105 by motor mounting brackets 501.
[0034] To achieve intelligent identification of waste, the cleaning transport vehicle is also equipped with a camera module 3. The camera module 3 is installed on the upper front side of the lightweight compartment and is electrically connected to a control device located inside the lightweight compartment. In this embodiment, the camera module uses a MaixCAM camera to acquire images of the front of the cleaning transport vehicle, then identifies whether there are objects in front of it from the images and determines whether the objects are waste, and then sends the relevant signals to the control device.
[0035] The control device includes a main control board and a power supply module. The main control board is the core control board of the cleaning transport vehicle, equipped with an STM32F427IIH6 chip for deploying control programs. The main control board is electrically connected to the camera module 3, the roller brush drive motor 9, and the travel drive motor 3, thereby realizing the omnidirectional movement and automated throughput control functions of the cleaning transport vehicle. The main control board is also wirelessly connected to a remote control device for remote control of the cleaning transport vehicle. The power supply module supplies power to the camera module 3, the roller brush drive motor 9, and the travel drive motor 3, among other electrical devices. The main control board and the power supply module are respectively mounted on two hardware mounting plates 7 and 6 of the lightweight compartment. The control device also includes brushless ESCs, a power distribution board, hardware connection cables, and tactile button switches, which are also centrally located on the rear hardware mounting plate 6 to keep the interior of the lightweight compartment cleaner and reduce the likelihood of unexpected malfunctions during operation.
[0036] The working principle of the cleaning transport vehicle provided by this utility model is as follows: During the movement of the cleaning transport vehicle, the camera module first acquires an image of the front, identifies whether there is an object in front and determines whether the object is waste, and sends relevant signals to the control device. If it is determined to be an obstacle rather than waste, the two drive motors 3 are controlled to rotate at different speeds to turn around it. If it is determined to be waste, the two drive motors 3 are controlled to rotate at the same speed, and the front roller brush 801 is controlled to rotate forward and the rear roller brush 802 is controlled to rotate in the opposite direction, sucking the waste into the receiving space located between the front roller brush 801 and the rear roller brush 802, while preventing the waste from leaving the receiving space during the movement of the cleaning transport vehicle, thus realizing the storage function during the movement. When the cleaning transport vehicle moves to the target position, the front roller brush 801 and the rear roller brush 802 are controlled to rotate forward or in the opposite direction at the same time to discharge the waste from the rear or front of the cleaning transport vehicle.
[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its scope of protection shall still fall within the protection scope of this utility model.
