Description

Technical Field

[0001] This invention relates to the field of robotics, and more particularly to a chassis for a disinfection robot. Background Technology

[0002] Against the backdrop of the ongoing construction of public health and safety systems and the increasing demand for cleaning and disinfection in various venues, disinfection has become a crucial link in protecting human health and preventing the spread of diseases. Whether it is a public place with dense crowds such as hospitals, schools, and shopping malls, or a special scenario with strict hygiene requirements such as food processing workshops and laboratories, efficient and thorough disinfection operations need to be carried out regularly. As a result, disinfection robots have emerged. Ultraviolet disinfection robots have been widely used in various disinfection scenarios due to their advantages such as good disinfection effect and no chemical residue. The robot chassis, as the core component for the disinfection robot to move and carry various functional modules, directly determines the overall working performance of the disinfection robot.

[0003] However, existing ultraviolet disinfection robots typically require high total power to achieve efficient disinfection, leading to a significant increase in power consumption. To ensure sufficient battery life for long-term, large-scale disinfection operations, the battery capacity must be increased. However, this inevitably results in a larger battery size, placing higher demands on the chassis's spatial layout. Furthermore, the working environments of ultraviolet disinfection robots are often complex and diverse, frequently encountering uneven surfaces. To ensure the robot maintains its driving force and stable movement when traversing these obstacles, shock-absorbing mechanisms are usually designed on the chassis's drive wheels. Traditional shock-absorbing mechanisms often employ horizontal or other complex structures, which, while achieving some degree of shock absorption, often suffer from structural complexity, poor stability, difficult assembly, and large space requirements within the chassis. Therefore, a new chassis design for disinfection robots is urgently needed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to address the technical problems existing in the background art by proposing a disinfection robot chassis.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A disinfection robot chassis includes a support plate, an ultraviolet lamp assembly, and a drive mechanism. The support plate has an assembly frame, in which a battery is installed. The ultraviolet lamp assembly is mounted on the assembly frame and electrically connected to the battery. The ultraviolet lamp assembly includes a front ultraviolet lamp assembly and two side ultraviolet lamp assemblies, each mounted on one of the three sides of the assembly frame. The drive mechanism is mounted on the assembly frame and electrically connected to the battery to drive the disinfection robot chassis to move. The drive mechanism includes a motor connecting plate, two shock-absorbing components, and motor wheels. Limiting grooves are provided on both sides of the first surface of the motor connecting plate. The two shock-absorbing components are respectively mounted on the assembly frame and connected to the motor connecting plate. The motor wheels are mounted on the motor connecting plate. The shock-absorbing components include a sliding member, a limiting block, and an elastic member. One end of the sliding member is mounted on the support plate, and the other end of the sliding member is slidably connected to the motor connecting plate. One end of the limiting block is mounted on the sliding member, and the other end of the limiting block is slidably connected to the corresponding limiting groove. Both ends of the elastic member are connected to the sliding member and the motor connecting plate, respectively.

[0007] Preferably, the sliding member includes a guide rail, a slide block, and a fixed seat. The guide rail is mounted on the motor connecting plate, the slide block is slidably connected to the guide rail, the fixed seat is mounted on the slide block and fixedly connected to the support plate, the limiting block is mounted on the fixed seat and slidably connected to the corresponding limiting groove, and the two ends of the elastic member are respectively connected to the fixed seat and the motor connecting plate.

[0008] Preferably, the elastic element includes a tension spring.

[0009] Preferably, the fixed base is provided with a first spring lug, the motor connecting plate is provided with a second spring lug, and the two ends of the tension spring are respectively hung on the first spring lug and the second spring lug.

[0010] Preferably, the front ultraviolet lamp group and the two side ultraviolet lamp groups each include multiple ultraviolet lamps arranged in an array.

[0011] Preferably, the chassis of the disinfection robot also includes a motor flange, which is mounted on a motor connecting plate and used to assemble motor wheels.

[0012] Preferably, the chassis of the disinfection robot also includes multiple anti-collision strips, which are respectively arranged on both sides of the support plate.

[0013] Preferably, the chassis of the disinfection robot also includes navigation sensors mounted on a support plate.

[0014] Preferably, the chassis of the disinfection robot also includes a charging module mounted on a support plate, and the charging module is electrically connected to the battery.

[0015] Preferably, the motor connecting plate is provided with a wire groove, in which a wire is installed. One side of the wire is connected to the battery, and the other side of the wire is connected to the motor wheel. Several wire pressing blocks are installed on the outside of the wire groove on the motor connecting plate.

[0016] Compared with the prior art, the invention has the following beneficial technical effects:

[0017] 1. This invention integrates the battery into the assembly frame by setting up a support plate and an assembly frame, thereby achieving orderly partitioned assembly of the battery, ultraviolet lamp group, and drive mechanism. This compact and reasonable space planning does not require excessive redundant space to accommodate large-capacity batteries. It not only meets the high power supply requirements of the ultraviolet lamp group for efficient disinfection, but also successfully adapts to the installation conditions of large-capacity batteries.

[0018] 2. By setting up a drive mechanism, this invention enables the motor wheels to slide stably up and down within a specified stroke. The tension spring is always in a stretched state after installation, which can continuously provide downward pressure to the motor wheels, ensuring that the motor wheels are always in close contact with the ground when the robot moves on uneven and complex ground. This effectively avoids loss of driving force, reduces interruption of disinfection or positional deviation caused by bumps, and ensures the continuity and uniformity of disinfection operations.

[0019] 3. By installing front ultraviolet lamps and two side ultraviolet lamps on three sides of the assembly frame, this invention can more comprehensively cover the front area of ​​the disinfection robot chassis, effectively carry out sterilization and disinfection, and ensure environmental cleanliness and hygiene.

For example, they can refer to a fixed connection, a link, or a specific connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the connection within two groups. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0030] like Figures 1-4As shown, the present invention proposes a disinfection robot chassis, which includes a support plate 1, an ultraviolet lamp group 4, and a drive mechanism 5. The support plate 1 is provided with an assembly frame 2, wherein a battery 3 is installed in the assembly frame 2. The ultraviolet lamp group 4 is installed on the assembly frame 2 and electrically connected to the battery 3. The ultraviolet lamp group 4 includes a front ultraviolet lamp group 18 and two side ultraviolet lamp groups 19 respectively installed on three sides of the assembly frame 2. The drive mechanism 5 is installed on the assembly frame 2 and electrically connected to the battery 3 for driving the disinfection robot chassis to move.

[0031] The drive mechanism 5 includes a motor connecting plate 7, two shock absorber components, and a motor wheel 17. The first surface of the motor connecting plate 7 is provided with limit grooves 12 on both sides. The two shock absorber components are respectively installed on the mounting frame 2 and connected to the motor connecting plate 7. The motor wheel 17 is installed on the motor connecting plate 7. The shock absorber component includes a sliding member, a limit block 11, and an elastic member 14. One end of the sliding member is installed on the support plate 1, and the other end of the sliding member is slidably connected to the motor connecting plate 7. One end of the limit block 11 is installed on the sliding member, and the other end of the limit block 11 is slidably connected to the corresponding limit groove 12. The two ends of the elastic member 14 are respectively connected to the sliding member and the motor connecting plate 7.

[0032] It should be noted that casters 6 are provided at the four corners of the bottom of the support plate 1 to cooperate with the movement of the motor wheels 17. The casters 6 are casters with shock absorption structure to ensure stability during movement. The assembly frame 2 has a rectangular structure. Therefore, the front ultraviolet lamp group 18 and the two side ultraviolet lamp groups 19 are respectively set on three adjacent sides of the rectangular structure. The front ultraviolet lamp group 18 is set at the front of the assembly frame 2 and serves as the forward direction of the disinfection robot chassis. The other two side ultraviolet lamp groups 19 are respectively set on two opposite sides of the rectangular structure and are adjacent to the front ultraviolet lamp group 18. This ensures that when the disinfection robot chassis is started and navigating, the front ultraviolet lamp group 18 and the two side ultraviolet lamp groups 19 can illuminate the front area of ​​the disinfection robot chassis.

[0033] There are two drive mechanisms 5, which are symmetrically arranged on both sides of the support plate 1, as shown in the attached figure. Figure 1As shown, there are two motor wheels 17 as the power source for the chassis of the disinfection robot. Of course, the number of motor wheels 17 is not limited; it can be one or more, depending on the actual application scenario, assembly method, and R&D cost. If only one motor wheel 17 is set, it is located at the bottom of the support plate 1 and near the middle. It can be set closer to the center or at both ends, so that the chassis of the disinfection robot is front-driven or rear-driven. Each drive mechanism 5 includes two shock-absorbing components, which act directly on the motor wheel 17 and the motor connecting plate 7, so that the motor wheel 17 has a certain buffering effect and improves the adaptability of the chassis of the disinfection robot to different road conditions.

[0034] In one embodiment of this application, the sliding member includes a guide rail 8, a slide block 9, and a fixed base 10. The guide rail 8 is mounted on the motor connecting plate 7, the slide block 9 is slidably connected to the guide rail 8, the fixed base 10 is mounted on the slide block 9 and is fixedly connected to the support plate 1, the limiting block 11 is mounted on the fixed base 10 and is slidably connected to the corresponding limiting groove 12, and the two ends of the elastic member 14 are respectively connected to the fixed base 10 and the motor connecting plate 7.

[0035] In one embodiment of this application, the elastic element 14 includes a tension spring.

[0036] The fixed base 10 is provided with a first spring lug 13, and the motor connecting plate 7 is provided with a second spring lug 15. The two ends of the tension spring are respectively hung on the first spring lug 13 and the second spring lug 15.

[0037] It should be noted that the guide rail 8 is directly fixed to the motor connecting plate 7, and its direction is vertical, as shown in the attached figure. Figure 3 and appendix Figure 4 As shown, the fixed base 10 is slidably connected to the guide rail 8 via the slide 9, allowing the fixed base 10 to move along the guide rail 8. To reduce the sliding stroke of the fixed base 10, a limiting groove 12 is provided on the motor connecting plate 7, and a limiting block 11 is installed on the fixed base 10. The end of the limiting block 11 away from the fixed base 10 extends directly into the limiting groove 12, thus limiting the sliding stroke of the fixed base 10 to the size range of the limiting groove 12. Furthermore, an elastic element 14 is provided as an important structure for shock absorption. In this embodiment, the elastic element 14 is selected as a tension spring structure. In application, the tension spring 14 is in a stretched state, providing a continuous downward force to the motor wheel 17, ensuring that the motor wheel 17 always has downward pressure on the ground during the movement of the support plate 1, thus ensuring the shock absorption effect of the chassis of the disinfection robot.

[0038] In one embodiment of this application, the front ultraviolet lamp group 18 and the two side ultraviolet lamp groups 19 each include a plurality of ultraviolet lamps arranged in an array.

[0039] It should be noted that the arrangement of multiple ultraviolet lamps is determined according to the actual application, and the front ultraviolet lamp group 18 and the two side ultraviolet lamp groups 19 also include reflectors. The reflectors are set behind the multiple ultraviolet lamps to control the radiation range of ultraviolet rays, so that they are concentrated in the front position of the disinfection robot chassis, avoiding ultraviolet rays from radiating to other unnecessary places, improving the radiation effect of ultraviolet rays and the disinfection efficiency of the disinfection robot chassis.

[0040] In one embodiment of this application, the chassis of the disinfection robot also includes a motor flange 16, which is mounted on the motor connecting plate 7 and used to assemble the motor wheels 17.

[0041] In one embodiment of this application, the chassis of the disinfection robot also includes a plurality of anti-collision strips 21, which are respectively disposed on both sides of the support plate 1.

[0042] In one embodiment of this application, the chassis of the disinfection robot also includes a navigation sensor 20 mounted on a support plate 1.

[0043] In one embodiment of this application, the chassis of the disinfection robot further includes a charging module 22 mounted on a support plate 1, and the charging module 22 is electrically connected to the battery 3.

[0044] In one embodiment of this application, the motor connecting plate 7 is provided with a wire groove 23, and a wire 24 is installed in the wire groove 23. One side of the wire 24 is connected to the battery 3, and the other side of the wire 24 is connected to the motor wheel 17. Several wire pressing blocks 25 are installed on the outside of the wire groove 23 on the motor connecting plate 7.

[0045] It should be noted that the above descriptions are one or more embodiments provided in conjunction with specific content, and do not imply that the specific implementation of the present invention is limited to these descriptions. Any methods or structures that are similar to or identical to those of the present invention, or any technical deductions or substitutions made based on the concept of the present invention, should be considered within the scope of protection of the present invention.
