Description

Technical Field

[0001] The utility model relates to the technical field of intelligent household appliances, in particular to a collision device for a glass-wiping robot. Background Art

[0002] A glass-cleaning robot is a type of smart home appliance. It creates a vacuum between the body and the glass through the vacuum suction cup or fan at the bottom of the body, so that it can be firmly adsorbed on the glass. It is mainly square in structure and usually has functions such as regular path, window frame detection, and automatic window cleaning. It can clean or automatically clean the glass wall.

[0003] Window-cleaning robots need to be equipped with physical collision sensors. Existing products all have side collision sensors, and sensors are not installed at the four corners. They cannot be used in complex working environments. The sides of the window-cleaning robots are prone to collide with the window frames, causing the rubber strips of the window frames to fall off, affecting the normal use of the window-cleaning robots.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0011] In an optional solution, the screw passes through the fixing piece and is connected to the connecting column.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The collision device used for the glass-cleaning robot consists of collision sensing coils at the four corners of the outer shell. When the glass-cleaning robot collides with the window frame, the collision sensing coils first contact the window frame and control the robot to move in the opposite direction, preventing the robot from colliding with the side and causing damage, and avoiding strong collisions that cause the window frame rubber strip to fall off, making the collision sensing of the glass-cleaning robot more sensitive and suitable for complex working environments.

In the drawings and descriptions, similar or identical parts are denoted by the same reference numerals, and in actual applications, the shape, thickness, or height of each component may be enlarged or reduced. The various embodiments listed in the present invention are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Any obvious modifications or changes made to the present invention do not depart from the spirit and scope of the present invention.

[0022] In one embodiment, Figure 1-5 As shown, a collision device for a glass-wiping robot comprises a shell 1, a bracket 2 is provided at the bottom of the shell 1, the bracket 2 and the shell 1 constitute the shell part of the glass-wiping robot, collision grooves 3 are provided at the four corners of the bottom of the bracket 2, and collision induction coils 4 are provided inside the four collision grooves 3. The collision induction coils 4 do not contact the inner walls of the collision grooves 3. The outer dimensions of the collision induction coils 4 are 1.7 mm larger than the dimensions of the two sides of the robot body, so that the four collision induction coils 4 protrude from the four corners of the shell 1. When a collision occurs, it is ensured that the collision induction coils 4 can first contact the glass frame. Transmission frames 12 are provided at the four corners of the bracket 2, and a connecting piece 14 is provided at the bottom of the transmission frame 12. The collision induction coils 4 is sleeved on the outside of the connecting piece 14, and a connecting column 7 is provided inside the collision sensing circle 4. The bottom end of the connecting column 7 passes through the collision sensing circle 4 and is provided with a rolling ball 8. The rolling ball 8 fits with the bottom of the collision sensing circle 4. The bottom of the rolling ball 8 is smooth and contacts the outer surface of the glass, which can support the entire glass-wiping robot. A mounting groove 15 is provided inside the bracket 2, and a touch switch 9 and a sleeve 10 are provided inside the mounting groove 15. Touch switches 9 are distributed on both sides of each transmission frame 12. The sleeve 10 is sleeved on the outside of the button of the touch switch 9. The sleeve 10 is subjected to force and triggers the touch switch 9. A transmission ring 16 is provided on the transmission frame 12, and the transmission ring 16 is in contact with the outside of the sleeve 10.

[0023] The collision device for the glass-cleaning robot consists of a collision sensing coil 4, a touch switch 9 and a transmission frame 12. The four collision sensing coils 4 are distributed at the four corners of the outer shell 1. When the glass-cleaning robot collides with the window frame, the collision sensing coil 4 first contacts the window frame to prevent the window frame rubber strip from falling off due to a strong collision. The collision sensing coil 4 controls the glass-cleaning robot to move in the opposite direction through the touch switch 9, making the collision sensing of the glass-cleaning robot more sensitive. As an embodiment, the left, right, up and down positions of the various components given in the accompanying drawings are only an arrangement method, and the specific positions are set according to specific needs.

[0024] In one embodiment, Figure 4As shown, a fixing frame 6 is provided at the bottom of the transmission frame 12 , and a buckle 5 connected to the bracket 2 is provided on the fixing frame 6 , and the transmission frame 12 is installed on the bracket 2 through the fixing frame 6 .

[0025] In one embodiment, Figure 4 As shown, the transmission frame 12 is provided with a connecting column 11 , and the transmission frame 12 is provided on the bracket 2 through the connecting column 11 .

[0026] In one embodiment, Figure 1-4 As shown, a fixing member 13 is provided on the top of the transmission frame 12 , and a screw is provided on the fixing member 13 . The screw passes through the fixing member 13 and is connected to the connecting column 7 .

[0027] In the above embodiment of the present invention, a collision device for a glass-wiping robot is provided. The glass-wiping robot is adsorbed on the glass window and cleans the glass. When the machine moves to the glass window frame, the two collision sensing coils 4 close to the side of the window frame first contact the glass frame. The slight collision force causes the two collision sensing coils 4 to move toward the inside of the machine. The inward movement distance is about 1.7 mm. The collision sensing coils 4 drive the transmission frame 12 to rotate. The transmission frame 12 squeezes the sleeve 10 through the transmission ring 16, triggering the internal touch switch 9 to be closed. The two pins inside the touch switch 9 are connected to the MCU control chip. After receiving the instruction, the MCU sends a control signal to prompt the machine to change its walking direction, and the machine moves in the opposite direction. After walking in the opposite direction, the collision sensing coils 4 reset and return to their original positions.

[0028] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
