Description
Technical Field
[0001] This utility model relates to the field of cleaning, and in particular to a quick-release structure for a cleaning robot's roller brush. Background Technology
[0002] Solar photovoltaic (PV) panels, as the name suggests, are panels used to utilize solar energy. In actual use, dust and other dirt will accumulate on the PV panels, which will inevitably cause abnormal temperatures in the areas with dirt. Prolonged abnormal temperatures can easily damage the PV panels and reduce their lifespan. Not only that, it will also affect the power generation efficiency of the PV panels. Therefore, PV cleaning robots have emerged to solve the problem of surface dirt on PV panels.
[0003] There are various forms of existing photovoltaic cleaning robots. For example, the robot provided by the patent with announcement number CN114985403A has a simple structure, but the distance between the moving slots of this robot is fixed, and it can only be applied to photovoltaic panels of a single width. For multiple spliced photovoltaic panels, it can only produce products of different sizes for adaptation, which is costly and not very universal.
[0004] Existing technologies also include cleaning robots that can walk directly on photovoltaic panels, without being limited by the size of the photovoltaic panels; however, the roller brush assembly and drive assembly of such cleaning robots are usually fixedly connected. Although the product consistency is better, the cleaning robot will generate vibration when walking on the photovoltaic panel, which requires the connection structure between the roller brush assembly and the drive assembly to have high strength and is not conducive to maintenance and replacement of parts; therefore, how to realize a quick disassembly and assembly structure between the roller brush assembly and the drive assembly is a technical problem that needs to be solved in this field. Utility Model Content
[0005] To address the aforementioned problems in the prior art, this utility model provides a quick-assembly structure for a cleaning robot's roller brush.
[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:
[0007] A quick-assembly structure for a cleaning robot's roller brush includes a first connector mounted on a roller brush assembly; the first connector is detachably connected to a second connector mounted on a main body; the first connector includes a mounting groove; the mounting groove has a sliding groove arranged along its depth direction; the bottom surface of the mounting groove has a positioning hole; the second connector includes a connecting block for connecting to the main body; the connecting block is connected to a slider that mates with the mounting groove and an elastic abutment portion disposed away from the slider; the slider has a protruding sliding limit block that mates with the sliding groove; a limit post that mates with the positioning hole is movably connected to the slider; the elastic abutment portion abuts against the main body.
[0008] In one embodiment of this utility model, there are two first connecting members.
[0009] In one embodiment of this utility model, two sliding grooves are arranged opposite to each other in the mounting groove.
[0010] In one embodiment of this utility model, a connecting rod is rotatably connected to the main body; the connecting block is fixedly connected to the connecting rod.
[0011] In one embodiment of this utility model, the end of the sliding limiting block near the first connecting member is an arc portion.
[0012] In one embodiment of this utility model, the end of the limiting post facing away from the positioning hole is provided with an adjustment part for adjusting the distance of the limiting post extending from the end face of the slider.
[0013] In one embodiment of this utility model, the adjusting part is fixedly connected to the limiting post; the limiting post is threadedly connected to the slider, and the distance of the limiting post extending beyond the end face of the slider is adjusted by rotating the limiting post.
[0014] In one embodiment of this utility model, the adjusting part is fixedly connected to the limiting post; the slider is provided with a receiving groove that cooperates with the limiting post; the limiting post is provided with a retaining ring located in the receiving groove; the slider is provided with a baffle that is disposed opposite to the retaining ring; a return spring is sleeved on the limiting post and located between the baffle and the retaining ring; the two ends of the return spring abut against the baffle and the retaining ring respectively.
[0015] In one embodiment of the present invention, the elastic abutment part includes a threaded post connected to the connecting block; a nut is threadedly connected to the threaded post; an abutment block is slidably connected to the end of the threaded post away from the slider; and a spring is sleeved on the threaded post between the nut and the abutment block.
[0016] In one embodiment of this utility model, a sliding rod is fixedly connected to the abutment block; a sliding groove that mates with the sliding rod is provided in the middle of the threaded column; the spring is fixedly connected to the abutment block; and an abutment piece that mates with the abutment block is provided on the main body.
[0017] The beneficial effects of this utility model are as follows: the mounting groove is provided with a sliding groove along its depth direction, and the slider has a sliding limit block that cooperates with the sliding groove. This cooperation method makes the connection between the roller brush assembly and the main body smoother and more precise. Through the guiding effect of the sliding groove and the sliding limit block, it can be ensured that the roller brush assembly accurately aligns with the main body during installation, and can slide along a specific direction during installation and disassembly, which is convenient for operation.
[0018] The bottom surface of the mounting groove is provided with positioning holes, and a limiting post that mates with the positioning hole is movably connected to the slider. When the roller brush assembly is installed into the main body, the limiting post can be inserted into the positioning hole to position and fix it, preventing the roller brush assembly from shaking or shifting during use, thus improving the stability and reliability of the connection between the roller brush assembly and the main body.
[0019] The elastic abutment on the connecting block is positioned away from the slider direction and abuts against the main body. This elastic abutment provides a certain amount of elastic force, ensuring a tight contact between the roller brush assembly and the main body after installation, further enhancing the stability of the connection. Simultaneously, the elastic abutment also acts as a buffer, reducing the impact of vibrations and other factors on the connection structure between the roller brush assembly and the main body during the cleaning robot's operation, thus extending the service life of the connection structure.

[0030] Example:
[0031] like Figure 1-3 As shown, a quick-assembly structure for a cleaning robot roller brush includes a first connector 100 disposed on a roller brush assembly 10; the first connector 100 is detachably connected to a second connector 200 disposed on a main body 20; the first connector 100 includes a mounting groove 110; a sliding groove 120 is provided in the mounting groove 110 along the depth direction of the mounting groove 110; a positioning hole 130 is provided on the bottom surface of the mounting groove 110; the second connector 200 includes a connecting block 210 for connecting to the main body 20; a slider 220 that cooperates with the mounting groove 110 and an elastic abutment portion 230 disposed away from the slider 220 are connected to the connecting block 210; a sliding limiting block 221 that cooperates with the sliding groove 120 is protruded on the slider 220; a limiting post 223 that cooperates with the positioning hole 130 is movably connected to the slider 220; the elastic abutment portion 230 abuts against the main body 20.
[0032] The mounting groove 110 has a groove 120 extending along its depth, and the slider 220 has a sliding limit block 221 that mates with the groove 120. This mating method makes the connection between the roller brush assembly 10 and the main body 20 smoother and more precise. Through the guiding effect of the groove 120 and the sliding limit block 221, it can be ensured that the roller brush assembly 10 accurately mates with the main body 20 during installation, and can slide along a specific direction during installation and disassembly, facilitating operation.
[0033] The bottom surface of the mounting groove 110 is provided with a positioning hole 130, and a limiting post 223 that mates with the positioning hole 130 is movably connected to the slider 220. When the roller brush assembly 10 is installed into the main body 20, the limiting post 223 can be inserted into the positioning hole 130 to play a role in positioning and fixing, preventing the roller brush assembly 10 from shaking or shifting during use, and improving the stability and reliability of the connection between the roller brush assembly 10 and the main body 20.
[0034] The elastic abutment portion 230 on the connecting block 210 is positioned away from the slider 220 and abuts against the main body 20. The elastic abutment portion 230 provides a certain elastic force, ensuring a tight contact between the roller brush assembly 10 and the main body 20 after installation, further enhancing the stability of the connection. Simultaneously, the elastic abutment portion 230 also acts as a buffer, reducing the impact of vibrations and other factors on the connection structure between the roller brush assembly 10 and the main body 20 during the cleaning robot's operation, thus extending the service life of the connection structure.
[0035] In one embodiment of this utility model, two first connectors 100 are provided. The two first connectors 100 can cooperate with the second connector 200 from different positions, increasing the connection points between the roller brush assembly 10 and the main body 20, dispersing the connection force. Compared to a single connector, it can better withstand various forces generated by the roller brush during operation, such as friction and torque, thereby effectively preventing the roller brush assembly 10 from shaking, shifting, or falling off during operation, improving the stability and reliability of the connection. The two first connectors 100 can be positioned and connected at different parts of the roller brush assembly 10, helping to more accurately determine the position of the roller brush assembly 10 relative to the main body 20, ensuring the roller brush is installed in the correct position, and guaranteeing the fitting accuracy between the roller brush and other components of the main body 20.
[0036] In one embodiment of this utility model, two sliding grooves 120 are arranged opposite each other within the mounting groove 110. The two opposing sliding grooves 120 provide more precise guidance for the sliding limit block 221 on the slider 220. When installing the roller brush assembly 10, the slider 220 can be accurately inserted into the mounting groove 110 simultaneously along the directions of the two sliding grooves 120, making the docking between the roller brush assembly 10 and the main body 20 more precise, reducing deviations and shaking during installation, and improving installation efficiency and accuracy. The two sliding grooves 120 cooperate with the corresponding structures on the slider 220 to limit and support the slider 220 from both sides, and compared to a single sliding groove 120, can better withstand the lateral forces and torques generated by the roller brush during operation.
[0037] In one embodiment of this utility model, a connecting rod 22 is rotatably connected to the main body 20; the connecting block 210 is fixedly connected to the connecting rod 22. The connecting rod 22 can rotate around the main body 20, allowing the connecting block 210 and the connected second connecting member 200 to rotate closer to or further away from the first connecting member 100 on the roller brush assembly 10. During installation, the connecting rod 22 can be rotated to a suitable angle, making it easier for the second connecting member 200 to mate with the first connecting member 100; the rotatably connected connecting rod 22 allows the roller brush assembly 10 to adjust its angle within a certain range. For example, when the cleaning robot encounters obstacles of different shapes or heights, the roller brush assembly 10 can adaptively adjust through the rotation of the connecting rod 22, allowing the roller brush to better conform to the ground or bypass obstacles, improving the passability and cleaning effect of the cleaning robot. During the operation of the cleaning robot, the roller brush may encounter various bumps and vibrations. The rotating connection of the connecting rod 22 can play a buffering role to a certain extent. When the roller brush is subjected to vibration or impact, the connecting rod 22 can absorb some energy by rotating slightly, reducing the vibration and impact transmitted to the main body 20.
[0038] In one embodiment of this utility model, the end of the sliding limiting block 221 near the first connecting member 100 is an arc portion 222. The design of the arc portion 222 allows the sliding limiting block 221 to more easily guide the slider 220 into the groove 120 of the mounting groove 110 when it is near the first connecting member 100. During installation, even if there is a certain angular deviation or positional error between the slider 220 and the groove 120, the arc portion 222 can still act as a guide, allowing the slider 220 to slide smoothly into the groove 120, reducing jamming and resistance during installation, and improving the convenience and success rate of installation.
[0039] In one embodiment of the present invention, the end of the limiting post 223 that is away from the positioning hole 130 is provided with an adjustment part 224 for adjusting the distance between the end face of the limiting post 223 and the end face of the slider 220.
[0040] In one embodiment of this utility model, the adjusting part 224 is fixedly connected to the limiting post 223; the limiting post 223 is threadedly connected to the slider 220, and the distance of the limiting post 223 extending out of the end face of the slider 220 is adjusted by rotating the limiting post 223.
[0041] In one embodiment of this utility model, the adjusting part 224 is fixedly connected to the limiting post 223; the slider 220 is provided with a receiving groove 225 that cooperates with the limiting post 223; the limiting post 223 is provided with a retaining ring 226 located in the receiving groove 225; the slider 220 is provided with a baffle 228 disposed opposite to the retaining ring 226; a return spring 227 is sleeved on the limiting post 223 between the baffle 228 and the retaining ring 226; the two ends of the return spring 227 abut against the baffle 228 and the retaining ring 226 respectively. During the installation and disassembly of the roller brush, when an external force is applied to the limiting post 223 to move it, the return spring 227 can push the limiting post 223 back to its initial position after the force disappears.
[0042] like Figure 4 As shown, during installation, the adjusting part 224 is pulled to the left to align the limiting post 223 with the positioning hole 130. After installation, the return spring 227 will automatically press / insert the limiting post 223 into the positioning hole 130, ensuring the stability of the connection. During disassembly, the adjusting part 224 is pulled outward to disengage the limiting post 223 from the positioning hole 130. After releasing, the return spring 227 will spring the limiting post 223 back for use in the next installation. This automatic reset function improves the convenience of operation. The retaining ring 226 and the baffle 228 limit the movement range of the limiting post 223 within the receiving groove 225, ensuring that the limiting post 223 will not move excessively and disengage from the receiving groove 225 or damage other components. At the same time, they also provide a fixed support point for the return spring 227, allowing the return spring 227 to function better and ensuring the stability and reliability of the entire structure.
[0043] In one embodiment of this utility model, the elastic abutment part 230 includes a threaded post 231 connected to the connecting block 210; a nut 232 is threadedly connected to the threaded post 231; an abutment block 233 is slidably connected to the end of the threaded post 231 away from the slider 220; a spring 235 is sleeved on the threaded post 231, located between the nut 232 and the abutment block 233; the spring 235 is sleeved on the threaded post 231, located between the nut 232 and the abutment block 233. When the roller brush assembly 10 is installed in place, the elastic force of the spring 235 allows the abutment block 233 to tightly abut against the corresponding part of the roller brush assembly 10, thereby achieving elastic abutment. This can buffer the vibration and impact force received by the roller brush assembly 10 during the operation of the cleaning robot, reduce wear and loosening between components, and improve the stability and reliability of the connection.
[0044] In one embodiment, the spring 235 is fixedly connected to the abutment block 233. By rotating the nut 232, the position of the nut 232 on the threaded post 231 can be adjusted, thereby compressing or stretching the spring 235, changing the elastic force of the spring 235, and thus adjusting the abutment force of the abutment block 233 on the roller brush assembly 10. This design allows for flexible adjustment of the abutment force according to different roller brush assemblies 10 or working conditions, ensuring a stable and reliable connection between the roller brush assembly 10 and the main body 20.
[0045] In one embodiment of this utility model, a sliding rod 234 is fixedly connected to the abutment block 233; a sliding groove cooperating with the sliding rod 234 is provided in the middle of the threaded column 231; the spring 235 is fixedly connected to the abutment block 233; and an abutment piece 21 cooperating with the abutment block 233 is provided on the main body 20. The abutment block 233 and the abutment piece 21 cooperate to provide stable abutment support for the roller brush assembly 10. In one embodiment, the abutment piece 21 is a metal sheet; the cooperation between the sliding rod 234 and the sliding groove plays a precise guiding role, restricting the abutment block 233 to move only along the direction of the sliding groove. This not only ensures that the abutment block 233 can accurately abut against and disengage from the abutment piece 21 under the action of the spring 235, but also avoids the abutment block 233 from shifting or shaking during movement, thus improving the stability and reliability of the entire structure.
[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
