Description

Technical Field

[0001] This utility model relates to the field of cleaning robots, specifically a controller for cleaning robots. Background Technology

[0002] With the rapid development of the smart home industry, cleaning robots have become important cleaning equipment for homes and commercial spaces due to their automated and intelligent cleaning capabilities. As the core component of cleaning robots, the controller is responsible for coordinating and planning the cleaning path, driving the actuators, and receiving sensor feedback signals. Its performance directly affects the cleaning efficiency, operational stability, and user experience of the cleaning robot. The controller of a cleaning robot mainly includes its internal circuit board and the electronic control system on the circuit board.

[0003] Currently, when installing the circuit board of a cleaning robot, the circuit board needs to be installed in the corresponding slot in the middle frame. However, due to the small space of the slot and the obstructed view during installation, it is difficult to directly observe the inside of the slot. Therefore, it is difficult to accurately align the position of the circuit board inside the slot, making it difficult to align the screw holes of the circuit board and the slot, thus reducing the efficiency of circuit board installation. Therefore, a controller for cleaning robots is proposed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and avoid the problem of low installation efficiency due to difficulty in aligning circuit boards, this utility model proposes a controller for cleaning robots.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a controller for a cleaning robot, including a robot frame, an installation groove is provided inside the robot frame, a fixing block is fixedly connected to the bottom wall of the middle part of the installation groove, a circuit board is provided on the top of the fixing block, a limiting component is provided inside the fixing block, and an adsorption component is provided inside the fixing block.

[0006] The limiting component includes two sliders fixedly installed at the middle of the left and right sides of the bottom of the circuit board. The top of the fixed block has two mounting slots on the left and right sides. The circuit board has side slots on the left and right sides of the mounting slots. The bottom wall of the side slot is fixedly connected to a fixing rod. The surface of the fixing rod is provided with a pressure spring. The surface of the fixing rod is slidably connected to a sliding plate. The inner wall of the side slot away from the mounting slot is fixedly connected to a hollow tube. The hollow tube is slidably connected to a solid rod. The surface of the solid rod is fixedly connected to a damping block. The end of the solid rod away from the hollow tube is fixedly connected to a pressure plate. The side wall of the side slot is fixedly connected to a return spring.

[0007] Preferably, the side groove is L-shaped, the side groove and the mounting groove are connected, the sliding plate is L-shaped, the top end of the pressure spring is fixedly connected to the bottom end of the sliding plate, and the elastic force of the pressure spring will push the sliding plate to move upward continuously.

[0008] Preferably, the top of the sliding plate extending into the inner side of the mounting groove contacts the bottom of the slider, and the side wall of the sliding plate away from the slider is adapted to fit against the end of the pressure plate away from the solid rod. The top of the side wall of the sliding plate abuts against the surface of the pressure plate, so that the pressure plate always remains in the state of compressing the return spring.

[0009] Preferably, the solid rod extends to the outside of the hollow tube, the damping block is slidably connected to the inner wall of the hollow tube, and the end of the return spring away from the side wall of the side groove is fixedly connected to the surface of the pressure plate. Through the damping between the damping block and the inner wall of the hollow tube, the pressure plate will not vibrate due to excessive movement speed or rebound after the return spring pushes the pressure plate to move under the action of elasticity.

[0010] Preferably, a rubber block is fixedly connected to the end of the pressure plate away from the solid rod. The pressure plate and the slider are in contact through the rubber block. At this time, the friction between the pressure plate and the slider increases, thereby stably limiting the slider.

[0011] Preferably, iron blocks are fixedly connected to the four corners of the bottom of the circuit board, and plastic shells are fitted onto the surface of the iron blocks. Hollow blocks are fixedly connected to both the front and rear ends of the second mounting slot. Magnetic blocks are fixedly connected to the bottom wall of the hollow blocks. A sliding groove is opened at the bottom of the hollow blocks, and a sliding rod is slidably connected inside the sliding groove. A baffle is fixedly connected to one end of the sliding rod near the middle of the second mounting slot. An inner groove is opened inside the robot frame, and a rotating rod is rotatably connected inside the inner groove. A pull rope is wound around the bottom surface of the rotating rod.

[0012] Preferably, the plastic shell is fitted into the interior of the hollow block, and the diameter of the baffle is larger than the inner diameter of the hollow block. The baffle can block the iron block and the magnetic block, thereby reducing the attraction between the iron block and the magnetic block.

[0013] Preferably, the inner groove has an L-shaped cross-section, and the top of the inner groove extends through the top of the robot's frame. The fixing block has a transverse groove connected to the inner groove on the side near the inner groove, allowing the rotating rod inside the inner groove to be rotated from the top of the robot's frame.

[0014] Preferably, the sliding rod is adapted to slide inside the transverse groove and the inner groove, and the end of the pull rope away from the rotating rod is fixedly connected to the surface of the sliding rod. When the rotating rod is rotated to wind the pull rope, the pull rope will pull the sliding rod and the baffle to move horizontally until the baffle moves between the iron block and the magnetic block inside the hollow block.

[0015] The advantages of this utility model are:

[0016] This invention, when the circuit board is placed on top of the fixing block inside the first mounting slot, allows the adjustable circuit board to be positioned directly by inserting an iron block into the hollow block. After the iron block is inserted, the iron block and the magnetic block attract each other, thus defining the position of the circuit board. Simultaneously, when the circuit board moves the slider into the second mounting slot, the pressure plate abuts against the side wall of the slider, further defining the slider. At this point, the position of the circuit board is fixed by the friction between the pressure plate and the slider, as well as the attraction between the iron block and the magnetic block. This fixing process does not require observation of the narrow interior of the first mounting slot, thus improving the efficiency of circuit board installation. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a controller for a cleaning robot. (See also...) Figure 1 A controller for a cleaning robot includes a robot frame 1, an installation groove 2 is provided inside the robot frame 1, a fixing block 3 is fixedly connected to the bottom wall of the middle part of the installation groove 2, a circuit board 4 is provided on the top of the fixing block 3, a limiting component 5 is provided inside the fixing block 3, and an adsorption component 6 is provided inside the fixing block 3.

[0027] Reference Figures 2-3 The limiting component 5 includes two sliders 51 fixedly installed on the middle of the left and right sides of the bottom end of the circuit board 4. The top of the fixing block 3 is provided with mounting grooves 521 on both the left and right sides. The circuit board 4 is provided with side grooves 522 on both the left and right sides of the mounting grooves 521. The bottom wall of the side grooves 522 is fixedly connected to the fixing rods 531. The surface of the fixing rods 531 is provided with pressure springs 532. The surface of the fixing rods 531 is slidably connected to the sliding plate 533. The side grooves 522 are L-shaped and communicate with the mounting grooves 521. The sliding plate 533 is L-shaped. The top end of the pressure springs 532 is fixedly connected to the bottom end of the sliding plate 533. The elastic force of the pressure springs 532 will push the sliding plate 533 to move upward continuously.

[0028] A hollow tube 541 is fixedly connected to the inner wall of the side groove 522 away from the mounting groove 521. A solid rod 542 is slidably connected inside the hollow tube 541. A damping block 543 is fixedly connected to the surface of the solid rod 542. A pressure plate 55 is fixedly connected to the end of the solid rod 542 away from the hollow tube 541. A rubber block is fixedly connected to the end of the pressure plate 55 away from the solid rod 542. The pressure plate 55 and the slider 51 are in contact through the rubber block. At this time, the friction between the pressure plate 55 and the slider 51 increases, thereby stably limiting the slider 51. A return spring 56 is fixedly connected to the side wall of the side groove 522. The sliding plate 533 extends to the top of the side inside the mounting groove 521 and contacts the slider 51. At the bottom, the side wall of the sliding plate 533 away from the slider 51 is adapted to fit against the end of the pressure plate 55 away from the solid rod 542. The top of the side wall of the sliding plate 533 abuts against the surface of the pressure plate 55, so that the pressure plate 55 always keeps the return spring 56 compressed. The solid rod 542 extends to the outside of the hollow tube 541. The damping block 543 is slidably connected to the inner wall of the hollow tube 541. The end of the return spring 56 away from the side wall of the side groove 522 is fixedly connected to the surface of the pressure plate 55. Through the damping between the damping block 543 and the inner wall of the hollow tube 541, after the return spring 56 pushes the pressure plate 55 to move under the action of elasticity, the pressure plate 55 will not cause the slider 51 to vibrate due to excessive movement speed or rebound.

[0029] Reference Figures 4-5Iron blocks 611 are fixedly connected to the four corners of the bottom of the circuit board 4. A plastic shell 612 is fitted onto the surface of each iron block 611. Hollow blocks 62 are fixedly connected to both the front and rear ends of the mounting slot 521. A magnetic block 63 is fixedly connected to the bottom wall of each hollow block 62. A sliding groove 64 is provided at the bottom of the hollow block 62. A sliding rod 651 is slidably connected inside the sliding groove 64. A baffle 652 is fixedly connected to one end of the sliding rod 651 near the middle of the mounting slot 521. The plastic shell 612 is fitted into the hollow block 62. The diameter of the baffle 652 is larger than the inner diameter of the hollow block 62. The baffle 652 can block the iron blocks 611 and the magnetic blocks 63, thereby reducing the attractive force between them. An inner groove 661 is provided inside the robot frame 1. The inner groove 661 is rotatably connected to a rotating rod 662. A pull rope 663 is wound around the bottom surface of the rotating rod 662. The cross-section of the inner groove 661 is L-shaped, and the top of the inner groove 661 passes through the top of the robot frame 1. The fixed block 3 has a transverse groove on the side near the inner groove 661 that communicates with the inner groove 661. The rotating rod 662 inside the inner groove 661 can be rotated from the top of the robot frame 1. The sliding rod 651 is adapted to slide and connect to the transverse groove and the inner groove 661. The end of the pull rope 663 away from the rotating rod 662 is fixedly connected to the surface of the sliding rod 651. When the rotating rod 662 is rotated to wind the pull rope 663, the pull rope 663 will pull the sliding rod 651 and the baffle 652 to move horizontally until the baffle 652 moves between the iron block 611 and the magnetic block 63 inside the hollow block 62.

[0030] Working principle: The operator first aligns the circuit board 4 to be installed with the upper part of the fixing block 3 inside the first mounting slot 2. Then, the slider 51 at the bottom of the circuit board 4 is placed into the inside of the second mounting slot 521. At this time, the circuit board 4 can be slid back and forth slightly until the iron block 611 and the plastic shell 612 at the bottom of the circuit board 4 can be inserted into the hollow block 62. Then, the circuit board 4 is slowly pressed down.

[0031] At this time, circuit board 4 drives the bottom slider 51 to press down on the sliding plate 533. The sliding plate 533 slides down on the surface of the fixed rod 531 and compresses the pressure spring 532 until the side wall of the sliding plate 533 disengages from the pressure plate 55. At this time, the pressure plate 55 will be pushed towards the slider 51 under the rebound force of the compressed return spring 56. During this process, the pressure plate 55 will pull the solid rod 542 to slide inside the hollow tube 541. At the same time, the solid rod 542 will drive the damping block 543 to slide inside the hollow tube. Inside 541, due to the damping effect between the damping block 543 and the hollow tube 541, the solid rod 542 slides out of the hollow tube 541 at a low speed. When the return spring 56 pushes the pressure plate 55 against the surface of the slider 51, the return spring 56 will not rebound due to the damping effect of the damping block 543 and the inner wall of the hollow tube 541. Therefore, the pressure plate 55 is stably against the surface of the slider 51, and the pressure plate 55 initially restricts the slider 51.

[0032] Furthermore, during the downward movement of the circuit board 4, the circuit board 4 will drive the iron block 611 and the plastic shell 612 to move downward. The plastic shell 612 will be inserted into the interior of the hollow block 62, and the friction between the plastic shell 612 and the hollow block 62 will further constrain the circuit board 4. At this time, as the iron block 611 and the magnetic block 63 gradually approach each other, the mutual attraction between the iron block 611 and the magnetic block 63 will gradually increase. Therefore, the attraction between the two can further constrain the circuit board 4. At this time, the operator can stably install the circuit board 4 without observing the narrow inner wall of the mounting slot 2.

[0033] When it is necessary to disassemble circuit board 4, the operator can use tools such as hexagons to rotate the top of the rotating rod 662. At this time, the rotating rod 662 will wrap around the pull rope 663 and pull the sliding rod 651, so that the sliding rod 651 pulls the baffle 652 to move into the hollow block 62 until the baffle 652 blocks between the iron block 611 and the magnetic block 63, thereby reducing the attraction between the two. Then, the operator can use tools or manually push the slider 51 or the plastic shell 612 upward from the left and right sides of the mounting slot 2, so that the circuit board 4 overcomes the friction between the plastic shell 612 and the hollow block 62 and the friction between the slider 51 and the pressure plate 55 and moves out of the mounting slot 2, thus completing the disassembly of circuit board 4.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
