Description

Technical Field

[0002] The conventional navigation and obstacle avoidance method of cleaning equipment is to navigate through a lidar (which can rotate 360 degrees) placed above the robot, and to avoid obstacles through a line lidar or a camera placed in front of the robot; however, since the line lidar placed on the front side of the robot cannot rotate, it can only avoid obstacles on the front side of the robot, and there are blind spots behind and on the sides of the robot when the robot turns.

[0049] The optical component 10 according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0050] As Figures 4 - 7 shown, the optical component 10 according to an embodiment of the present utility model is for a cleaning device 100 and includes: a body 1, a first light emitter / receiver 2, and a second light emitter / receiver 3.

[0051] Specifically, referring to Figures 4 - 6 , the body 1 is an integral part and the body 1 is rotatably provided on the cleaning device 100; the first light emitter / receiver 2 is provided on the body 1; the second light emitter / receiver 3 is provided on the body 1, and the first light emitter / receiver 2 and the second light emitter / receiver 3 can work simultaneously.

[0052] Among them, it should be noted that the optical component 10 can be a lidar. The first light emitter / receiver 2 has a transmitter head and / or a receiver. The transmitter head can emit laser light. When the laser light irradiates an obstacle, part of the light will be reflected back to the first light emitter / receiver 2, and the receiver head receives the reflected light. By processing the optical signal, navigation or obstacle avoidance is achieved. Similarly, the second light emitter / receiver 3 can emit laser light. When the laser light irradiates an obstacle, part of the light will be reflected back to the second light emitter / receiver 3, and the second light emitter / receiver 3 receives the reflected light.

[0053] By processing the optical signal received by one of the first light emitter / receiver 2 and the second light emitter / receiver 3, the navigation of the cleaning device 100 can be achieved. By processing the optical signal received by the other one, the obstacle avoidance of the cleaning device 100 can be achieved. The body 1 has a controller, and the controller has multiple threads. The multiple threads include a first thread and a second thread. The first thread is used to control the first light emitter / receiver 2 to emit and receive laser light, and the second thread is used to control the second light emitter / receiver 3 to emit and receive laser light, so as to achieve that the first light emitter / receiver 2 and the second light emitter / receiver 3 can work simultaneously. Compared with the situation where the first light emitter / receiver and the second light emitter / receiver need to work independently, the detection efficiency of the optical component 10 is improved.

[0054] It can be understood that since both the first light emitter / receiver 2 and the second light emitter / receiver 3 are provided on and connected to the main body 1, and the main body 1 is rotatably provided on the cleaning device 100, wherein the rotation axis of the main body 1 extends in the up and down direction. Thus, the first light emitter / receiver 2 and the second light emitter / receiver 3 can also rotate with the rotation of the main body 1, so that one of the first light emitter / receiver 2 and the second light emitter / receiver 3 can navigate at any angle in the circumferential direction of the cleaning device 100, and the other can avoid obstacles at any angle in the circumferential direction of the cleaning device 100, reducing the obstacle avoidance blind area in the circumferential direction of the cleaning device 100. Therefore, there is no need to set additional sensors for obstacle avoidance, making the structure simple, optimizing the cost, making the control of the cleaning device 100 more flexible, and reducing the occurrence of deadlock situations.

[0055] According to the optical component 10 of the embodiment of the present invention, the main body 1 is an integral part and the main body 1 is rotatably provided on the cleaning device 100; the first light emitter / receiver 2 is provided on the main body 1; the second light emitter / receiver 3 is provided on the main body 1, so that the first light emitter / receiver 2 and the second light emitter / receiver 3 can also rotate with the rotation of the main body 1, so that one of the first light emitter / receiver 2 and the second light emitter / receiver 3 can navigate at any angle in the circumferential direction of the cleaning device 100, and the other can avoid obstacles at any angle in the circumferential direction of the cleaning device 100, reducing the obstacle avoidance blind area in the circumferential direction of the cleaning device 100. Therefore, there is no need to set additional sensors for obstacle avoidance, making the structure simple, optimizing the cost, making the control of the cleaning device 100 more flexible, and reducing the occurrence of deadlock situations.

[0056] In some embodiments of the present invention, as Figure 4 and Figure 6 shown, the main body 1 includes: a first support portion 11, a first mounting portion 12, a second support portion 13, a second mounting portion 14, and a connecting portion 17.

[0057] Specifically, as Figure 4 and Figure 6 shown, the first support portion 11 and the second support portion 13 are spaced apart, the connecting portion 17 is provided between the first support portion 11 and the second support portion 13 and is connected to both the first support portion 11 and the second support portion 13, and the first support portion 11 and the second support portion 13 extend in the up and down direction; the first mounting portion 12 is provided at the upper end of the first support portion 11, and the first light emitter / receiver 2 is provided on the first mounting portion 12, the second mounting portion 14 is provided at the upper end of the second support portion 13, and the second light emitter / receiver 3 is provided on the second mounting portion 14.

[0058] It can be understood that the first supporting portion 11 and the second supporting portion 13 are spaced apart, so that the first mounting portion 12 and the second mounting portion 14 can be spaced apart, so that the first light emitter / receiver 2 and the second light emitter / receiver 3 can be spaced apart, thereby avoiding working interference between the first light emitter / receiver 2 and the second light emitter / receiver 3.

[0059] In some embodiments of the present invention, Figure 4 and Figure 6 As shown, in the direction from the first supporting portion 11 to the second supporting portion 13 , the connecting portion 17 extends obliquely upward, the first mounting portion 14 extends in the horizontal direction, and the second mounting portion 14 extends obliquely downward. The second mounting portion 14 is located on the upper side of the first mounting portion 12 .

[0060] It should be noted that the second mounting portion 14 is located on the upper side of the first mounting portion 12 , which is not limited to the second mounting portion 14 and the first mounting portion 12 being arranged relative to each other in the up and down directions. The second mounting portion 14 and the first mounting portion 12 may also be arranged in a staggered manner.

[0061] It can be understood that the first mounting portion 14 extends in the horizontal direction, so that the first light emitter / receiver 2 extends in the horizontal direction, so that the first light emitter / receiver 2 can emit a laser extending in the horizontal direction, and the laser propagates in the horizontal direction, so that the laser can propagate the farthest path, thereby facilitating the navigation of the cleaning device 100.

[0062] Furthermore, if Figure 4 and Figure 6 As shown, the second mounting portion 14 extends downwardly at an angle, so that the second light emitter / receiver 3 extends downwardly at an angle, thereby facilitating the second light emitter / receiver 3 to emit light that is tilted downward, thereby facilitating the laser to illuminate obstacles on the ground and obstacles near the cleaning device 100, thereby facilitating obstacle avoidance of the cleaning device 100. The second mounting portion 14 is located on the upper side of the first mounting portion 12, so that the second light emitter / receiver 3 is located on the upper side of the first light emitter / receiver 2, thereby increasing the coverage of the laser of the second light emitter / receiver 3, thereby improving the obstacle avoidance capability.

[0063] In some embodiments of the present invention, Figure 4 and Figure 6 As shown, the first mounting portion 12 is disposed on a side of the first supporting portion 11 away from the second supporting portion 13 , and the second mounting portion 14 is disposed on a side of the second supporting portion 13 away from the first supporting portion 11 .

[0064] As a result, the directions in which the first light transmitter / receiver 2 and the second light transmitter / receiver 3 emit light can be opposite, thereby preventing the light emitted by the first light transmitter / receiver 2 from being reflected back and received by the second light transmitter / receiver 3, and also preventing the light emitted by the second light transmitter / receiver 3 from being reflected back and received by the first light transmitter / receiver 2, thereby avoiding mutual interference between the first light transmitter / receiver 2 and the second light transmitter / receiver 3 during operation, thereby improving the accuracy of navigation and obstacle avoidance.

[0065] In addition, the frequencies and wavelengths of the lasers emitted by the first optical transmitter / receiver 2 and the second optical transmitter / receiver 3 are different, thereby further avoiding mutual interference between the first optical transmitter / receiver 2 and the second optical transmitter / receiver 3 during operation, thereby improving the accuracy of navigation and obstacle avoidance.

[0066] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the optical assembly 10 further includes: a light-transmitting cover 4 and a bracket 5 . The bracket 5 is disposed at the lower side of the light-transmitting cover 4 and connected to the light-transmitting cover 4 . An installation space 51 is formed between the bracket 5 and the light-transmitting cover 4 . The body 1 is disposed in the installation space 51 .

[0067] It is understandable that the arrangement of the light-transmitting cover 4 and the bracket 5 can prevent the main body 1 from being directly exposed to the external environment, thereby improving the protection of the main body 1 and increasing the service life of the main body 1. The light-transmitting cover 4 can allow the laser to pass through, thereby avoiding shielding the laser emitted by the first light emitter / receiver 2 and the second light emitter / receiver 3.

[0068] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the optical component 10 also includes: a motor component 6, which is arranged in the installation space 51 and on the lower side of the main body 1, and the motor component 6 includes a rotor 61 and a stator 62, the stator 62 is fixed on the bracket 5, and the rotor 61 is connected to the main body 1 for driving the main body 1 to rotate.

[0069] It can be understood that the rotor 61 has a mounting groove on the side facing away from the optical component 10, part of the bracket 5 is arranged in the mounting groove, the stator 62 is arranged in the mounting groove, the rotation axis of the rotor 61 extends in the up and down directions, the rotor 61 is connected to the main body 1, drives the main body 1 to rotate, thereby realizing that the main body 1 is rotatably arranged on the cleaning device 100, and the stator 62 is fixed on the bracket 5, thereby realizing the fixation of the stator 62, so that the motor assembly 6 works normally.

[0070] In some embodiments of the present invention, Figure 4 and Figure 5As shown, the rotor 61 is sleeved outside the stator 62. A second induction coil 615 is fixedly arranged on the outer peripheral wall of the rotor 61. A first induction coil 52 is arranged in the installation space 51. The first induction coil 52 is sleeved outside the second induction coil 615 and is arranged opposite to the second induction coil 615.

[0071] It can be understood that the first induction coil 52 is arranged on the inner peripheral wall of the bracket 5 and is fixed relative to the bracket 5. When the rotor 61 rotates, it drives the second induction coil 615 to rotate. Since the first induction coil 52 is fixed relative to the bracket 5, relative movement occurs between the first induction coil 52 and the second induction coil 615. An induced electromotive force is generated in the second induction coil 615. The second induction coil 615 is electrically connected to the first light emitter / receiver 2 and the second light emitter / receiver 3, so that an induced current is generated in the second induction coil 615, thereby realizing power supply for the first light emitter / receiver 2 and the second light emitter / receiver 3. Thus, it can be ensured that the first light emitter / receiver 2 and the second light emitter / receiver 3 can save electric energy while working normally.

[0072] In some embodiments of the present invention, as Figure 4 and Figure 5 shown, a rotational speed detector 614 is arranged on the rotor 61 for detecting the rotational speed of the rotor 61. Thus, through the monitoring of the rotational speed of the rotor 61 by the rotational speed detector 614, it is convenient for the cleaning device 100 to accurately control the rotational speed of the rotor 61, thereby accurately controlling the rotational speed of the main body 1, so that the first light emitter / receiver 2 and the second light emitter / receiver 3 can emit and receive laser at a specific rotational speed, thereby further improving the accuracy of navigation and obstacle avoidance.

[0073] Among them, the rotor 61 is sleeved outside the stator 62. A second induction coil 615 is fixedly arranged on the outer peripheral wall of the rotor 61. A first induction coil 52 is arranged in the installation space 51. The first induction coil 52 is sleeved outside the second induction coil 615 and is arranged opposite to the second induction coil 615. The second induction coil 615 is electrically connected to the rotational speed detector 614, thereby supplying power to the rotational speed detector 614 and realizing the operation of the rotational speed detector 614.

[0074] In some embodiments of the present invention, as Figure 4 and Figure 5As shown in the figure, the rotor 61 includes a rotating shaft 611. The rotating shaft 611 is rotatably arranged inside the stator 62. On the side of the rotating shaft 611 facing away from the main body 1, there is an avoidance groove 612. On the bottom wall of the avoidance groove 612, there is a data generation signal lamp 613. The data generation signal lamp 613 is communicatively connected to the first light transmitter / receiver 2 and the second light transmitter / receiver 3. On the side of the bracket 5 facing the main body 1, there is a data reception induction lamp 53. The data reception induction lamp 53 is connected to the bracket 5 and is communicatively connected to the controller of the cleaning device 100. The data generation signal lamp 613 and the data reception induction lamp 53 are arranged opposite to each other in the vertical direction. The data reception induction lamp 53 is used to receive the signal of the data generation signal lamp 613.

[0075] It can be understood that the communication connection between the data generation signal lamp 613 and the first light transmitter / receiver 2 and the second light transmitter / receiver 3 can be an indirect communication connection. For example, the data generation signal lamp 613, the first light transmitter / receiver 2, and the second light transmitter / receiver 3 are connected to the controller, and the communication connection between the data generation signal lamp 613 and the first light transmitter / receiver 2 and the second light transmitter / receiver 3 is realized through the controller in the main body 1. It can also be a direct communication connection.

[0076] The data generation signal lamp 613 transmits the light signals received by the first light transmitter / receiver 2 and the second light transmitter / receiver 3 to the data reception induction lamp 53, and the data reception induction lamp 53 transmits this signal to the controller of the cleaning device 100, so as to facilitate the movement and operation of the cleaning device 100.

[0077] In some embodiments of the present invention, as Figure 7 shown, the optical component 10 further includes: a third light transmitter / receiver 7. The third light transmitter / receiver 7 is arranged on the main body 1. It should be noted that the third light transmitter / receiver 7 can emit laser light. When the laser light irradiates an obstacle, part of the light will be reflected back to the third light transmitter / receiver 7, and the third light transmitter / receiver 7 receives the reflected light.

[0078] By processing the optical signals received by the third light transmitter / receiver 7, the obstacle avoidance ability of the cleaning device 100 can be further improved. The main body 1 has a controller, and the controller has multiple threads. The multiple threads further include a third thread, and the third thread is used to control the third light transmitter / receiver 7 to emit and receive laser light. Thus, the first light transmitter / receiver 2, the second light transmitter / receiver 3, and the third light transmitter / receiver 7 can work simultaneously. Compared with the case where the first light transmitter / receiver, the second light transmitter / receiver, and the third light transmitter / receiver need to work independently, the detection efficiency of the optical component 10 is improved.

[0079] It can be understood that since the third light emitter / receiver is provided on and connected to the main body 1, and the main body 1 is rotatably provided on the cleaning device 100, wherein the rotation axis of the main body 1 extends in the vertical direction. Thus, the third light emitter / receiver can rotate with the rotation of the main body 1, so that the third light emitter / receiver can avoid obstacles at any angle in the circumferential direction of the cleaning device 100, reducing the obstacle avoidance blind area in the circumferential direction of the cleaning device 100. Therefore, there is no need to provide additional sensors for obstacle avoidance, making the structure simple, optimizing the cost, making the control of the cleaning device 100 more flexible, and reducing the occurrence of deadlock situations.

[0080] In some embodiments of the present utility model, as Figure 7 shown, the main body 1 further includes: a third support portion 15 and a third mounting portion 16. The third support portion 15 extends in the vertical direction, and the third support portion 15 is provided on the upper side of the first support portion 11 and connected to the first support portion 11; the third mounting portion 16 is provided at the upper end of the third support portion 15, and the third light emitter / receiver 7 is provided on the third mounting portion 16.

[0081] It should be noted that the third support portion 15 is provided on the upper side of the first support portion 11, and it is not limited to the third support portion 15 and the first support portion 11 being relatively arranged in the vertical direction. The third support portion 15 and the first support portion 11 can also be arranged in a staggered manner in the circumferential direction of the optical component 100. As Figure 7 shown, when the third support portion 15 and the first support portion 11 are relatively arranged in the vertical direction, the space in the circumferential direction of the optical component 100 can be saved.

[0082] It can be understood that the third support portion 15 is provided on the upper side of the first support portion 11, the third mounting portion 16 is provided at the upper end of the third support portion 15, and the third light emitter / receiver 7 is provided on the third mounting portion 16, so that the third light emitter / receiver 7 can emit light in a higher area, facilitating the laser to irradiate higher obstacles, thereby improving the obstacle avoidance ability of the cleaning device 100 when passing through a height-limited area.

[0083] In some embodiments of the present utility model, when the third support portion 15, the first support portion 11, and the second support portion 13 are arranged and staggered in the circumferential direction of the optical component 100, the first mounting portion 12, the second mounting portion 14, and the third mounting portion 16 can be spaced apart in the circumferential direction of the optical component 100, so that the first light emitter / receiver 2, the second light emitter / receiver 3, and the third light emitter / receiver can be spaced apart in the circumferential direction of the optical component 100.

[0084] Thus, it is possible to prevent the light emitted by the first light transmitter / receiver 2 from being reflected back and received by the second light transmitter / receiver 3 or the third light transmitter / receiver, and it is also possible to prevent the light emitted by the second light transmitter / receiver 3 from being reflected back and received by the first light transmitter / receiver 2 or the third light transmitter / receiver, and it is also possible to prevent the light emitted by the third light transmitter / receiver 7 from being reflected back and received by the first light transmitter / receiver 2 or the second excitation emission receiving head, thereby avoiding the mutual interference when the first light transmitter / receiver 2, the second light transmitter / receiver 3 and the third light transmitter / receiver work, and improving the accuracy of navigation and obstacle avoidance.

[0085] In some embodiments of the present invention, the frequencies and wavelengths of the lasers emitted by the first light transmitter / receiver 2, the second light transmitter / receiver 3 and the third light transmitter / receiver are different, thereby further avoiding the mutual interference when the first light transmitter / receiver 2, the second light transmitter / receiver 3 and the third light transmitter / receiver work, and improving the accuracy of navigation and obstacle avoidance.

[0086] In some embodiments of the present invention, as Figure 7 shown, the third light transmitter / receiver 7 extends obliquely upward. It can be understood that the third light transmitter / receiver 7 extends obliquely upward, so as to facilitate the third light transmitter / receiver 7 to emit obliquely upward light, so as to facilitate the laser to irradiate an obstacle higher than the cleaning device 100, thereby further improving the obstacle avoidance ability of the cleaning device 100 passing through the height-limited area.

[0087] The cleaning device 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0088] As Figures 1 - 3 shown, the cleaning device 100 according to an embodiment of the present invention includes: a housing 20 and the above-mentioned optical assembly 10.

[0089] Specifically, as Figures 1 - 3 shown, the optical assembly 10 is provided on the housing 20. Among them, the cleaning device 100 can be a floor sweeping robot or the like.

[0090] According to the cleaning device 100 of the embodiments of the present utility model, by providing the above-mentioned optical component 10, the main body 1 is an integral part and the main body 1 is rotatably provided on the cleaning device 100; the first light emitting / receiving device 2 is provided on the main body 1; the second light emitting / receiving device 3 is provided on the main body 1, so that the first light emitting / receiving device 2 and the second light emitting / receiving device 3 can also rotate along with the rotation of the main body 1, thereby enabling one of the first light emitting / receiving device 2 and the second light emitting / receiving device 3 to perform navigation at any angle in the circumferential direction of the cleaning device 100, and the other to perform obstacle avoidance at any angle in the circumferential direction of the cleaning device 100, reducing the obstacle avoidance blind area in the circumferential direction of the cleaning device 100, so that there is no need to provide additional sensors for assisting in obstacle avoidance, making the structure simple, optimizing the cost, making the control of the cleaning device 100 more flexible, and reducing the occurrence of deadlock situations.

[0091] In some embodiments of the present utility model, as Figures 1 - 3 shown, the housing 20 has a receiving space 201, and a communication hole communicating with the receiving space 201 is provided on the upper surface of the housing 20. The optical component 10 is movable in the up and down direction to at least partially extend out of the receiving space 201 or retract into the receiving space 201 through the communication hole.

[0092] It can be understood that the optical component 10 is movable in the up and down direction. When the optical component 10 moves upward, the detection range of the optical component 10 increases, facilitating obstacle avoidance and navigation of the optical component 10. When passing through a height-limited area, the optical component 10 can move downward, so as to smoothly pass through the height-limited area. In addition, when the optical component 10 stops working, the optical component 10 moves downward and retracts into the receiving space 201, so that the housing 20 plays a protective role for the optical component 10, improving the service life of the optical component 10.

[0093] In some embodiments of the present utility model, as Figures 1 - 3 shown, the cleaning device 100 further includes: a lifting mechanism 30, the lifting mechanism 30 is provided in the receiving space 201 and is connected to the optical component 10 for driving the optical component 10 to move in the up and down direction. Thus, by providing the lifting mechanism 30, the optical component 10 can be moved in the up and down direction to at least partially extend out of the receiving space 201 or retract into the receiving space 201 through the communication hole.

[0094] Furthermore, as Figures 1 - 3As shown, the lifting mechanism 30 includes: a driving motor 302, a gear assembly and a screw rod 301, the screw rod 301 extends in the up-down direction, a nut 8 is connected to the optical component 10, the nut 8 is suitable for cooperating with the screw rod 301, and can move in the up-down direction along the screw rod 301, the output shaft of the driving motor 302 and the screw rod 301 are transmitted through the gear assembly, so that the output shaft of the driving motor 302 can drive the screw rod 301 to rotate, thereby driving the nut 8 to move in the up-down direction along the screw rod 301, thereby driving the optical component 10 to move in the up-down direction.

[0095] In some embodiments of the present invention, Figures 1 - 3 As shown, the cleaning device 100 further includes a guide rail 40, which is disposed in the accommodation space 201 and extends in the up-down direction, and the optical component 10 is movably disposed in the up-down direction on the guide rail 40. Thus, the provision of the guide rail 40 makes the movement of the optical component 10 more stable.
