Description

Technical Field

[0001] This utility model relates to the field of sweeping robot technology, specifically a wear-resistant protective outer ring component for a sweeping robot. Background Technology

[0002] Robotic vacuum cleaners, also known as automatic cleaning machines, smart vacuums, or robotic vacuum cleaners, are a type of smart home appliance. They can automatically clean floors in a room using artificial intelligence. They generally use brushing and vacuuming methods to suck up debris from the floor into their own dustbin, thus completing the floor cleaning function. Generally speaking, robots that can sweep, vacuum, and mop are also collectively classified as robotic vacuum cleaners.

[0003] Regarding the aforementioned technologies, many robotic vacuum cleaners currently consist mainly of a shell to protect the various internal components. However, when working, robotic vacuum cleaners pass by various furniture, obstacles, etc., and the shell of the robotic vacuum cleaner may collide with these obstacles. The probability of collisions increases significantly with frequent operation, which poses a risk of damage to the robotic vacuum cleaner.

[0004] To address this issue, the present invention provides a wear-resistant protective outer ring component for a sweeping robot. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a wear-resistant protective outer ring component for a sweeping robot, thus solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a wear-resistant protective outer ring component for a sweeping robot, including a sweeping robot body, a support component installed on the top of the sweeping robot body, and a protective component installed on the outer wall of the sweeping robot body;

[0007] The protective assembly includes several mounting brackets, which are uniformly and fixedly installed on the outer wall of the robot vacuum cleaner body. Limiting cavities are formed in the inner walls of the mounting brackets. Miniature dampers are installed on both the left and right sides of the inner walls of the limiting cavities. Buffer springs are installed on the outer walls of the miniature dampers. The front ends of two miniature dampers located within the same limiting cavity are fixedly mounted with the same limiting seat. Connecting blocks are fixedly installed on the front walls of the limiting seats. Connecting brackets are fixedly installed on both the left and right sides of the front walls of the connecting blocks. Arc-shaped protective rings are fixedly installed at the front ends of the connecting brackets on the same side. Mounting cavities are formed in the outer walls of the arc-shaped protective rings. Several protective rollers are uniformly and rotatably mounted on the inner walls of the mounting cavities.

[0008] Through the above technical solution, the protective components can prevent the robot vacuum cleaner body from making direct rigid contact with external obstacles, thus providing good protection for it.

[0009] Furthermore, the outer walls of several of the limiting seats are slidably connected to the inner walls of the corresponding limiting cavities, the outer walls of several of the protective rollers are made of wear-resistant rubber, and the top walls of several of the mounting frames are fixedly connected to the support components.

[0010] With the above technical solution, the outer wall of the limiting seat is slidably connected to the inner wall of the corresponding limiting cavity, which can prevent the limiting seat from shifting position.

[0011] Furthermore, the support component includes a protective frame, the interior of which is hollow, and the inner wall of the protective frame is located at the top of the robot vacuum cleaner body.

[0012] The above technical solution provides protection by installing a protective frame on the top of the robot vacuum cleaner.

[0013] Furthermore, the top wall of the protective frame is provided with a receiving groove, and a number of support seats are uniformly fixedly installed on the outer wall of the protective frame, and the top wall of each of the support seats is provided with a positioning hole.

[0014] Through the above technical solution, the position of the receiving slot is mainly matched with the position of the switch and the controller.

[0015] Furthermore, each of the mounting brackets has a positioning rod fixedly installed on its top wall. Each of the positioning rods is made of high-strength rubber, and the outer wall of each positioning rod is uniformly provided with anti-slip texture. The outer wall of each positioning rod is in contact with the inner wall of the corresponding positioning hole.

[0016] With the above technical solution, the positioning rod has a large frictional force after entering the corresponding positioning hole, which prevents it from coming off.

[0017] Furthermore, support blocks are fixedly installed on the bottom walls of several of the mounting brackets.

[0018] With the above technical solution, the support block provides good support when the entire device is under pressure.

[0019] Furthermore, a switch is installed on the top wall of the robot vacuum cleaner body, and a controller is installed at the rear of the top wall of the robot vacuum cleaner body.

[0020] Through the above technical solution, the switch is mainly used to control the opening and closing of the robot vacuum cleaner body, and the controller controls the working status of the robot vacuum cleaner body.

[0021] Beneficial effects

[0022] This invention provides a wear-resistant protective outer ring component for a robotic vacuum cleaner. Compared with the prior art, it has the following advantages:

[0023] (1) The wear-resistant protective outer ring assembly of this sweeping robot uses a protective frame to drive the support base to be placed on the top of the sweeping robot body. The support base fits against the top wall of the mounting bracket, allowing the positioning hole to be inserted and fixed into the inner wall of the positioning rod. The protective frame protects the top of the sweeping robot body, preventing it from knocking over obstacles and damaging the top of the sweeping robot body during operation. Furthermore, the overall installation of the protective frame is relatively simple, and it is not easily detached after installation. It provides good top protection for the sweeping robot body. When the protective roller contacts an obstacle, it drives... The arc-shaped protective ring and connecting frame squeeze the limiting seat, which slides into the inner wall of the limiting cavity inside the mounting frame. The limiting seat squeezes the buffer spring and micro damper to buffer the force generated by the collision. When the robot vacuum cleaner body drives the protective components to clean the floor, the rotating protective roller can prevent the arc-shaped protective ring from scratching the wall and leaving marks. The protective roller will rotate and move along the contacted object. At the same time, the protective roller has good friction resistance. Through the cooperation of the protective components and the support components, direct rigid contact can be prevented, which can provide good double protection for the robot vacuum cleaner body.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1:

[0032] Please see Figure 1-5 A wear-resistant protective outer ring component for a sweeping robot includes a sweeping robot body 1, a support component 3 installed on the top of the sweeping robot body 1, and a protective component 2 installed on the outer wall of the sweeping robot body 1.

[0033] The protective component 2 includes several mounting brackets 21, which are evenly and fixedly installed on the outer wall of the robot vacuum cleaner body 1. Limiting cavities 22 are formed in the inner walls of the mounting brackets 21. Miniature dampers 24 are installed on both the left and right sides of the inner walls of the limiting cavities 22. Buffer springs 23 are installed on the outer walls of the miniature dampers 24. The front ends of two miniature dampers 24 located inside the same limiting cavity 22 are fixedly mounted with the same limiting seat 25. Connecting blocks 26 are fixedly installed on the front walls of the limiting seats 25. If... Connecting brackets 27 are fixedly installed on both the left and right sides of the front wall of each connecting block 26. Arc-shaped protective rings 28 are fixedly installed at the front end of each connecting bracket 27 on the same side. Each arc-shaped protective ring 28 has an installation cavity 29 on its outer side wall. Each installation cavity 29 has a protective roller 210 evenly rotatably installed on its inner wall. Each limiting seat 25 has its outer wall slidably connected to the inner wall of its corresponding limiting cavity 22. Each protective roller 210 has its outer wall made of wear-resistant rubber. The top wall of each mounting bracket 21 is fixedly connected to the support component 3.

[0034] In this embodiment of the utility model, the purpose of this arrangement is that the protective component 2 can protect the external position of the robot body 1. When the robot body 1 collides with an obstacle during operation, the force generated by the collision will be buffered, which can avoid damage caused by direct rigid contact. The protective rollers 210 have good friction resistance, and the protective rollers 210 rotate past the obstacle after contacting it.

[0035] Example 2:

[0036] Please see Figure 1-5This embodiment provides a technical solution based on Embodiment 1: The support component 3 includes a protective frame 31, the interior of which is hollow. The inner wall of the protective frame 31 is located at the top of the robot body 1. The top wall of the protective frame 31 has a receiving groove 32. Several support seats 33 are uniformly fixedly installed on the outer wall of the protective frame 31. The top wall of each support seat 33 has a positioning hole 34. The top wall of each mounting bracket 21 has a positioning rod 35. The positioning rods 35 are made of high-strength rubber. The outer wall of each positioning rod 35 has uniform anti-slip textures. The outer wall of each positioning rod 35 fits against the inner wall of the corresponding positioning hole 34. The bottom wall of each mounting bracket 21 has a support block 36. A switch 4 is installed on the top wall of the robot body 1. A controller 5 is installed at the rear of the top wall of the robot body 1.

[0037] In this embodiment of the utility model, the purpose of this arrangement is that the support component 3 provides good protection for the top of the robot body 1 when it is working and it collides with an external obstacle, causing it to tip over. This prevents the external obstacle from hitting the top of the robot body 1 and causing damage. After the positioning hole 34 and the positioning rod 35 are interlocked, they have high friction and are not easy to detach.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] During operation, the movable protective frame 31 drives the support base 33 to be placed on top of the robot vacuum cleaner body 1. The support base 33 fits against the top wall of the mounting bracket 21, allowing the positioning hole 34 to insert and fix into the inner wall of the corresponding positioning rod 35. The receiving groove 32 aligns with the positions of the switch 4 and controller 5. Thus, the protective frame 31 protects the top of the robot vacuum cleaner body 1, preventing it from knocking over obstacles and damaging its top. The protective frame 31 is easy to install and does not easily detach after installation, providing excellent top protection for the robot vacuum cleaner body 1. When the robot vacuum cleaner body 1 bumps into an obstacle during operation, it first protects against... When the protective roller 210 comes into contact with an obstacle, upon collision, the protective roller 210 drives the arc-shaped protective ring 28 and the connecting frame 27 to squeeze the limiting seat 25. The limiting seat 25 slides into the inner wall of the limiting cavity 22 inside the mounting frame 21. The limiting seat 25 squeezes the buffer spring 23 and the micro damper 24 to buffer the force generated by the collision. When the robot vacuum cleaner 1 drives the protective component 2 to clean the ground, the rotation of the protective roller 210 can prevent the arc-shaped protective ring 28 from rubbing against the wall and leaving marks. The protective roller 210 will rotate and move along the object it contacts. At the same time, the protective roller 210 has good friction resistance. The setting of the protective component 2 can prevent direct rigid contact with the robot vacuum cleaner 1 and has a good protective effect.
