Detailed Implementation

[0019] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0021] like Figure 1 The vehicle-mounted device shown is suitable for installation at the bottom of a vehicle seat. The vehicle-mounted device includes a fan 2, a waste collection box 5, a robotic arm, and a vacuum head 14. The vacuum head 14 is installed at the end of the robotic arm, which is used to move the vacuum head 14 to adjust the vacuuming position of the vacuum head 14. The vacuum head 14, the waste collection box 5, and the fan 2 are connected in sequence through a channel. When the fan 2 is running, it can generate a suction airflow to draw the suction material at the vacuum head 14 into the waste collection box 5.

[0022] Using the above technical solution, the in-vehicle device can remove dust from the vehicle carpet, which helps improve the user experience and also makes reasonable use of the space under the vehicle seats, improving the utilization rate of the interior space. In specific implementation, the suction material includes dust, debris, and other waste on the vehicle carpet that can be sucked into the waste collection box 5.

[0023] In some embodiments, the vehicle-mounted device further includes a seat ventilation intake channel 18, a seat ventilation exhaust channel 20, a seat ventilation intake valve 19 disposed in the seat ventilation intake channel 18, and a seat ventilation exhaust valve 21 disposed in the seat ventilation exhaust channel 20. The output end of the seat ventilation intake channel 18 is connected to the input end of the fan 2, and the input end of the seat ventilation exhaust channel 20 is connected to the output end of the fan 2. Using the above technical solution, the vehicle-mounted device can also achieve car seat ventilation, and the device has a high degree of integration. Considering the large space between the vehicle seat and the vehicle carpet, combined with the current vehicle seat ventilation function, a multi-functional vehicle-mounted device integrating ventilation and dust removal is formed, improving the utilization rate of interior space and having the advantage of small footprint.

[0024] In some embodiments, the vehicle-mounted device further includes a dust extraction and exhaust channel 3 connected to the output end of the fan 2, a dust extraction and exhaust valve 4 is provided in the dust extraction and exhaust channel 3, and a dust extraction isolation valve 6 is provided between the input end of the fan 2 and the airflow output end of the garbage collection box 5.

[0025] In some embodiments, the robotic arm includes a vertical telescopic device 9, a rotary joint 10, and a horizontal telescopic device 13. A suction head 14 is mounted at the end of the horizontal telescopic device 13, and the root of the horizontal telescopic device 13 is connected to the lower end of the vertical telescopic device 9 via the rotary joint 10. Using the above technical solution, the vertical telescopic device 9 controls the raising and lowering of the suction head 14; the horizontal telescopic device 13 controls the horizontal extension and retraction of the suction head 14; and the rotary joint 10 controls the rotation of the suction head 14.

[0026] In practical implementation, an onboard controller can be used to control the operation of the robotic arm. The controller monitors the resistance received by the vertical telescopic device 9, the rotary joint 10, and the horizontal telescopic device 13 to determine if an obstacle has been encountered. When an obstacle is encountered, the robotic arm is controlled to avoid it. Furthermore, both the vertical telescopic device 9 and the horizontal telescopic device 13 can be hydraulic telescopic devices. The rotary joint 10 can be implemented using a rotary motor 11 and a transmission mechanism 12. For example, the rotary motor 11 is fixedly installed at the lower end of the vertical telescopic device 9, and the root of the horizontal telescopic device 13 is connected to the output end of the rotary motor 11 via the transmission mechanism 12, using the rotary motor 11 to drive the horizontal telescopic device 13 to rotate. The transmission mechanism 12 can be, but is not limited to, a gear transmission mechanism 12 or a belt transmission mechanism 12. During operation, the hydraulic pressure of the hydraulic telescopic device and the current of the rotary motor 11 can be detected to determine if the robotic arm has encountered an obstacle.

[0027] In some embodiments, the waste collection box 5 is provided with a waste isolation valve 8 and an air filter 7. The waste isolation valve 8 and the air filter 7 are used to trap waste inside the waste collection box 5, facilitating the formation of a multifunctional vehicle-mounted device that combines ventilation and dust removal.

[0028] In some embodiments, a suction inlet valve 16 is provided at the suction port 15 of the suction head 14, and an interface 17 for connecting an external handheld vacuum extension device 22 is provided on the suction head 14. Figure 4 As shown, the vehicle-mounted device can also achieve manual vacuuming control. After the manual suction function is turned on, the fan 2 is controlled to work, the vertical telescopic device 9 moves downward a certain distance, the rotary motor 11 stops, and the user can connect the handheld vacuuming extension device 22 through the interface 17, close the vacuuming air intake valve 16, and use the handheld vacuuming extension device 22 to vacuum the vehicle seats, vehicle carpets and other interior areas.

[0029] like Figure 2 As shown, when the vehicle-mounted device realizes the seat ventilation function, it controls the opening of the seat ventilation intake valve 19 and the seat ventilation exhaust valve 21, and controls the closing of the dust extraction exhaust valve 4, the dust extraction isolation valve 6, the garbage isolation valve 8, and the dust extraction intake valve 16. When the ventilation fan 2 rotates, it drives the airflow to enter through the seat ventilation intake valve 19 and exit through the seat ventilation exhaust valve 21, thus realizing the seat ventilation function.

[0030] like Figure 3As shown, when the vehicle-mounted device performs its vacuuming function, the vertical telescopic device 9 extends downwards, and the horizontal telescopic device 13 extends horizontally. The system controls the closing of the seat ventilation intake valve 19 and the seat ventilation exhaust valve 21, and controls the opening of the vacuum exhaust valve 4, vacuum isolation valve 6, garbage isolation valve 8, and vacuum intake valve 16. When the ventilation fan 2 rotates, it drives airflow from the vacuum intake valve 16 into the garbage collection box 5, and after passing through the air filter 7, it is discharged from the vacuum exhaust valve 4. Dust and other debris from the vehicle carpet are drawn into the garbage collection box 5 by the suction generated by the fan 2, isolated by the air filter 7, and retained inside the garbage collection box 5.

[0031] In practical implementation, the vehicle-mounted device includes a base 1, which is fixedly installed on the car seat base. The root of the robotic arm is connected to the base 1. The channel, valves, waste collection box 5, and fan 2 can all be set in the base 1. Each valve can be an electric valve controlled by a controller.

[0032] The present invention also proposes a dust collection method, employing any of the above-mentioned vehicle-mounted devices, the dust collection method comprising the following steps: Control the movement of the robotic arm to drive the vacuum head 14 to vacuum the preset carpet area 23.

[0033] In practice, the robotic arm can be controlled to move along a preset trajectory. When vacuuming the preset carpet area 23, the fan 2 can be controlled to generate suction airflow. In practice, the vehicle-mounted device can be controlled using a vehicle controller to achieve automatic vacuuming of the preset carpet area 23.

[0034] As a preferred example, vacuuming the preset carpet area 23 by driving the vacuum head 14 includes the following steps: The vacuum head 14 is driven to vacuum the circular area 2309 of the preset carpet area 23. The circular area 2309 is the area enclosed by a circle 2306 with the projection 2305 of the root of the robotic arm as the center and the width of the preset carpet area 23 in the left and right direction as the diameter. When vacuuming the circular area 2309, the path of the vacuum head 14 can be a spiral path that gradually extends outward, or a multi-layered circular path that expands outward in circles.

[0035] The vacuum head 14 is driven to vacuum the first annular fan-shaped area 2310 of the preset carpet area 23. The first annular fan-shaped area 2310 is the area enclosed by the front semicircle of the circle 2306, the left boundary 2303 of the preset carpet area 23, the right boundary 2304 of the preset carpet area 23, and the first arc 2307 centered on the projection 2305 of the root of the robotic arm and tangent to the front boundary 2301 of the preset carpet area 23. When vacuuming the first annular fan-shaped area 2310, the path of the vacuum head 14 can be a multi-layered arc-shaped path that gradually expands outward.

[0036] The vacuum head 14 is driven to vacuum the second annular fan-shaped area 2311 of the preset carpet area 23. The second annular fan-shaped area 2311 is the area enclosed by the rear semicircle of the circle 2306, the left boundary 2303 of the preset carpet area 23, the right boundary 2304 of the preset carpet area 23, and the second arc 2308 centered on the projection 2305 of the root of the robotic arm and tangent to the rear boundary 2302 of the preset carpet area 23. When vacuuming the second annular fan-shaped area 2311, the path of the vacuum head 14 can be a multi-layered arc-shaped path that gradually expands outward.

[0037] The vacuum head 14 is driven to vacuum the first corner area 2312 of the preset carpet area 23. The first corner area 2312 is the area enclosed by the first arc 2307, the left boundary 2303 of the preset carpet area 23, and the front boundary 2301 of the preset carpet area 23. When vacuuming the first corner area 2312, the path of the vacuum head 14 can be a multi-layered arc-shaped path that gradually expands outward.

[0038] The vacuum head 14 is driven to vacuum the second corner area 2313 of the preset carpet area 23. The second corner area 2313 is the area enclosed by the first arc 2307, the right boundary 2304 of the preset carpet area 23, and the front boundary 2301 of the preset carpet area 23. When vacuuming the second corner area 2313, the path of the vacuum head 14 can be a multi-layered arc-shaped path that gradually expands outward.

[0039] The vacuum head 14 is driven to vacuum the triangular area 2314 of the preset carpet area 23. The triangular area 2314 is the area enclosed by the second arc 2308, the left boundary 2303 of the preset carpet area 23, and the rear boundary 2302 of the preset carpet area 23. When vacuuming the triangular area 2314, the path of the vacuum head 14 can be a multi-layered arc-shaped path that gradually expands outward. The vacuum head 14 is driven to vacuum the fourth corner area 2315 of the preset carpet area 23. The fourth corner area 2315 is the area enclosed by the second arc 2308, the right boundary 2304 of the preset carpet area 23, and the rear boundary 2302 of the preset carpet area 23. When vacuuming the fourth corner area 2315, the path of the vacuum head 14 can be a multi-layered arc-shaped path that gradually expands outward.

[0040] By using the above-mentioned vacuuming method and rationally planning the vacuuming path, vacuuming efficiency can be improved and the difficulty of controlling the robotic arm can be reduced.

[0041] like Figure 5 As shown, the preset carpet area 23 is typically a rectangular area. The distance between the projection 2305 of the base of the robotic arm on the preset carpet area 23 and the front and rear boundaries of the rectangular area is typically greater than the distance between the projection 2305 and the left and right boundaries. When the controller activates the vacuuming function, it can locate the position of the vehicle-mounted device in the preset carpet area 23 of the vehicle carpet based on the position of the vehicle seat. The controller controls the vertical telescopic device 9 to achieve the up-and-down movement of the vacuum head 14, controls the horizontal telescopic device 13 to achieve the horizontal movement of the vacuum head 14, and controls the rotary joint 10 to achieve the horizontal rotation of the vacuum head 14.

[0042] As a specific example, the vacuuming method includes the following steps: Step 1: When vacuuming begins, the controller controls the vertical telescopic device 9 to move the vacuum head 14 downwards by a certain position, adjusting it to the preset vacuuming position. During this movement, the controller monitors the hydraulic pressure of the vertical telescopic device 9 in real time. When the hydraulic pressure reaches the pressure threshold, it determines that there is an obstacle at the bottom, controls the vertical telescopic device 9 to rise, reports the corresponding fault, and sends text or voice prompts to the user through the vehicle's infotainment system, or provides relevant prompts to the user via a mobile app.

[0043] Step 2: The controller controls the rotating joint 10 to rotate the vacuum head 14; every time the vacuum head 14 rotates a certain number of times, the horizontal telescopic device 13 is controlled to extend outward to a certain distance until the vacuuming of the circular area 2309 is completed.

[0044] Step 3: The controller controls the rotary joint 10 to rotate, turning the suction head 14 forward and causing it to swing. Each swing of the suction head 14 a certain number of times extends the horizontal telescopic device 13 forward a certain distance until the suction of the first annular fan-shaped area 2310 is completed. In Step 3, when the controller detects an obstacle encountered by the robotic arm, it controls the rotary joint 10 to reverse. The swing range of the suction head 14 can be determined based on the boundary of the first annular fan-shaped area 2310.

[0045] Step 4: The controller controls the rotating joint 10 to rotate the vacuum head 14 to the left front corner of the preset carpet area 23, causing the vacuum head 14 to swing. After a certain number of swings, the horizontal extension device 13 extends a certain distance to the left front corner until the vacuum head 14 reaches the left front corner, completing the vacuuming of the first corner area 2312. In Step 4, when the controller detects an obstacle encountered by the robotic arm, it controls the rotating joint 10 to reverse. The swing range of the vacuum head 14 can be determined based on the boundary of the first corner area 2312.

[0046] Step 5: The controller controls the rotating joint 10 to rotate the vacuum head 14 to the front right corner of the preset carpet area 23, causing the vacuum head 14 to swing. Each time the vacuum head 14 swings a certain number of times, the horizontal extension device 13 extends a certain distance to the front right corner until the vacuum head 14 reaches the front right corner, completing the vacuuming of the second corner area 2313. In Step 5, when the controller detects an obstacle encountered by the robotic arm, it controls the rotating joint 10 to reverse. The swing range of the vacuum head 14 can be determined based on the boundary of the second corner area 2313.

[0047] Step Six: The controller controls the rotary joint 10 to rotate, turning the suction head 14 to the rear and causing it to swing. Each time the suction head 14 swings a certain number of times, the horizontal telescopic device 13 extends rearward a certain distance until the suction of the second annular fan-shaped area 2311 is completed. In Step Six, when the controller detects an obstacle encountered by the robotic arm, it controls the rotary joint 10 to reverse. The swing range of the suction head 14 can be determined based on the boundary of the second annular fan-shaped area 2311.

[0048] Step Seven: The controller controls the rotating joint 10 to rotate the vacuum head 14 to the left rear corner of the preset carpet area 23, causing the vacuum head 14 to swing. After a certain number of swings, the horizontal extension device 13 extends a certain distance to the left rear corner until the vacuum head 14 reaches the left rear corner, completing the vacuuming of the third corner area 2314. In Step Seven, when the controller detects an obstacle encountered by the robotic arm, it controls the rotating joint 10 to reverse. The swing range of the vacuum head 14 can be determined based on the boundary of the third corner area 2314.

[0049] Step 8: The controller controls the rotary joint 10 to rotate the vacuum head 14 to the right rear corner of the preset carpet area 23, causing the vacuum head 14 to swing. After a certain number of swings, the horizontal extension device 13 extends a certain distance to the right rear corner until the vacuum head 14 reaches the right rear corner, completing the vacuuming of the fourth corner area 2315. In Step 8, when the controller detects an obstacle encountered by the robotic arm, it controls the rotary joint 10 to reverse. The swing range of the vacuum head 14 can be determined based on the boundary of the fourth corner area 2315.

[0050] Step 9: After vacuuming is complete, first retract the horizontal telescopic device 13, then retract the vertical telescopic device 9, close all valves, and stop the fan 2.

[0051] When the position of the vehicle seat changes, causing the position of the on-board device to change, the controller can automatically adjust the sequence of steps two through eight to complete the vacuuming function, which will not be described again here.
