1 to 5, the autonomous mobile device 100 of this embodiment can be used as a self-propelled sterilization robot or a handheld sterilization device. The autonomous mobile device 100 includes a body 110, a control module 120 (Figure 3), an ultraviolet light module 130 (Figure 3), a bottom cover 140 (Figure 5), a bottom cover sensor 150 (Figure 3), and a bottom distance sensor器155 (Figure 3).

In this embodiment, the body 110 may be the main body of the sweeping robot, and its interior may include a motor (not shown), a dust collection unit (not shown), a dust collection unit (not shown), etc., and include exposed parts. There are two wheels 116 (Figure 3), and can walk autonomously. Of course, in other embodiments, the autonomous mobile device 100 may also be a robot dedicated to sterilization, and it does not necessarily need to be equipped with the above-mentioned unit.

If the autonomous mobile device 100 is a sweeping robot, during the sweeping process, the ultraviolet light module 130 can be turned on to sterilize while sweeping, or it can be turned off, so that the autonomous mobile device 100 is only used as a sweeping robot.

In addition, in order to facilitate holding, the body 110 further includes a handle 112 (FIG. 1) on the top and a groove 114 under the handle 112. The groove 114 can facilitate the user's hand to reach in to hold the handle 112. In this embodiment, the handle 112 also has a telescopic function. As shown in FIG. 1, when the handle 112 is retracted, the top surface of the handle 112 does not exceed the top surface of the body 110, which avoids collision and is more beautiful. When using the hand-held function, the user can pull out the handle 112 as shown in FIG. 2 to make more space under the handle 112 and make it easier to hold.

In other embodiments, the recess 114 may not be provided under the telescopic handle, or the handle 112 may not be telescopic. Of course, the form of the handle 112 is not limited to this.

As shown in FIG. 3, the control module 120 is disposed in the body 110. The ultraviolet light module 130 is disposed at the bottom of the body 110 and is electrically connected to the control module 120. The control module 120 can control the ultraviolet light module 130 to turn on or off.

In this embodiment, the ultraviolet light module 130 includes a plurality of first ultraviolet light units 132 facing downward and a second ultraviolet light unit 134 facing diagonally downward. The first ultraviolet light unit 132 can sterilize the bottom. When the body 110 is close to a wall or an object, the second ultraviolet light unit 134 can illuminate the corner or the bottom of the object obliquely downward.

The autonomous mobile device 100 further includes a side distance sensor 170 disposed on the side of the body 110 and electrically connected to the control module 120. The side distance sensor 170 is, for example, an infrared sensor or an ultrasonic sensor. When the side distance sensor 170 senses that there is an object beside the body 110, the control module 120 turns on the second ultraviolet light units 134 to increase the angle range that the autonomous mobile device 100 can sterilize when traveling. That is to say, in this embodiment, the ultraviolet light module 130 can simultaneously irradiate downward and obliquely downward to sterilize at a large angle.

In addition, the body 110 further includes a light-transmitting protective cover 118, which is arranged on the ultraviolet light module 130 to prevent the ultraviolet light module 130 from being directly exposed. The material of the transparent protective cover 118 is, for example, acrylic or glass, but the material of the transparent protective cover 118 is not limited thereto.

As shown in FIG. 5, the bottom cover 140 is detachably disposed at the bottom of the body 110. As shown in FIG. 4, in this embodiment, when the autonomous mobile device 100 is used as an autonomous sterilization robot, the bottom cover 140 is not installed on the body 110, the wheels 116, the ultraviolet light module 130, and the bottom distance sensor 155 are exposed, and It can walk autonomously and can turn on the ultraviolet light module 130 to sterilize.

When the autonomous mobile device 100 is used as a handheld sterilization device (non-autonomous movement mode), as shown in FIG. 5, a bottom cover 140 is installed on the body 110, and the bottom cover 140 covers the wheels 116 (FIG. 4) and exposes the ultraviolet light module 130 And the bottom distance sensor 155. In this way, the dirt of the wheels 116 can be prevented from being stained on the sofa or bed sheets.

It is worth mentioning that in this embodiment, the bottom cover sensor 150 is disposed at the bottom of the body 110 and is electrically connected to the control module 120, and the bottom cover sensor 150 is used to detect whether the bottom cover 140 is installed The body 110 determines whether the autonomous mobile device 100 is a robot or a handheld sterilization device.

When the bottom cover sensor 150 senses that the bottom cover 140 is installed on the body 110, the control module 120 determines that the autonomous mobile device 100 is a handheld sterilization device, and can further activate the ultraviolet light module 130. In addition, when the autonomous mobile device 100 is used as a hand-held sterilization device, the control module 120 can put the wheel 116 in a disabled state to ensure that the wheel 116 does not rotate in this mode.

In this embodiment, the bottom cover sensor 150 includes a magnetic sensor, and the bottom cover 140 includes a magnetic member 142 corresponding to the bottom cover sensor 150. Of course, the type of the bottom cover sensor 150 is not limited by this. In other embodiments, the bottom cover sensor 150 includes a pressure sensor. When the bottom cover 140 is installed on the body 110, the bottom cover 140 presses the bottom cover sensor 150 to trigger the bottom cover sensor 150.

In addition, the bottom distance sensor 155 is disposed at the bottom of the body 110 and is electrically connected to the control module 120. The bottom distance sensor 155 is, for example, an infrared sensor or an ultrasonic sensor. The bottom distance sensor 155 is used to sense the distance between the body 110 and the object below. The distance exceeds the preset value (for example, 3 cm to 5 cm, but not limited to this), it means that the body 110 is too far away from the floor, desktop, sofa or bed below. At this time, if a child is under the body 110, it may Misfire of ultraviolet light occurs, causing harm to the human body/eyes. Therefore, when the distance exceeds the preset value, the control module 120 turns off the ultraviolet light module 130 to prevent the ultraviolet light from being misfired. In addition, the bottom distance sensor 155 can also detect the height difference below, so as to prevent the autonomous mobile device 100 from falling under the environment such as stairs.

In other words, if the autonomous mobile device 100 is used as a robot, the bottom cover sensor 150 can sense that the bottom cover 140 is not installed on the body 110. In addition, since the autonomous mobile device 100 will be placed on the ground, the bottom distance sensor 155 will sense that the body 110 keeps a certain distance from the ground. Therefore, the control module 120 can determine that this is the autonomous movement mode, and can choose to turn on the ultraviolet light module 130. If the robot is a sweeping robot, the control module 120 can also activate the dust collection and sterilization functions at the same time. Of course, the robot can also only automatically start the vacuum function, and allow the user to manually start the sterilization function.

In this embodiment, the autonomous mobile device 100 further includes an operating interface 172 (switch), which is electrically connected to the control module 120 to control the ultraviolet light module 130 to be turned on or off. The user can forcibly turn on the ultraviolet light module 130 through the operating interface 172. In addition, the autonomous mobile device 100 further includes an alarm 174 which is electrically connected to the control module 120. The warning device 174 includes, for example, a light source, a display, a buzzer, or a horn. When the ultraviolet light module 130 is forcibly turned on, the autonomous mobile device 100 can remind the user through the alarm 174.

If the autonomous mobile device 100 is used as a handheld sterilization device, the bottom cover sensor 150 will sense whether the bottom cover 140 is installed on the body 110, and the bottom distance sensor 155 will sense whether the body 110 is in contact with the object to be sterilized (sofa The distance between the bed), etc. does not exceed the predetermined distance. If yes, it means it is safe to use. The control module 120 can automatically turn on the ultraviolet light module 130 for sterilization. During the sterilization process, if the bottom distance sensor 155 senses that the distance between the body 110 and the object (sofa, bed) to be sterilized exceeds a predetermined distance, the control module 120 will turn off the ultraviolet light module 130.

In addition, in this embodiment, as shown in FIG. 4, two bottom distance sensors 155 are provided on the left and right of the bottom of the body 110, because the distance between the two bottom distance sensors 155 on the left and right sides is Larger than the width of a human face, the control module 120 can be set to turn on the ultraviolet light module 130 only when the two bottom distance sensors 155 on the left and right sides are close to the surface of the object, so as to effectively prevent the ultraviolet light from irradiating the eyes by mistake.

Furthermore, as shown in FIG. 4, the autonomous mobile device 100 is adapted to advance along a first direction D1, and the first ultraviolet light units 132 of the ultraviolet light module 130 are arranged along a second direction D2 perpendicular to the first direction D1. In order to increase the area that the autonomous mobile device 100 can sterilize when traveling.

In addition, the body 110 includes a posture sensor 176 disposed in the body 110 and electrically connected to the control module 120. The posture sensor 176 is used to detect the movement state of the autonomous mobile device 100. The attitude sensor 176 is, for example, a gyroscope, which can accurately detect the change in the rotation angle of the body 110, so that the body 110 can plow the field like a buffalo in the autonomous movement mode, and effectively increase the total ultraviolet light coverage with a regular parallel movement track. In addition, when the attitude sensor 176 determines that the body 110 is in an abnormal state that cannot move normally, the control module 120 can turn off the ultraviolet light module 130 according to this information.

Furthermore, in this embodiment, the body 110 includes a dirt sensor 178 disposed on the body 110 and electrically connected to the control module 120. The dirt sensing module is used to detect dirt. When the dirt reaches the trigger level, the control module 120 can drive the body 110 to repeatedly walk in the vicinity.

It is worth mentioning that, in this embodiment, the first ultraviolet light unit 132 and the second ultraviolet light unit 134 respectively include ultraviolet light emitting diodes. Of course, in other embodiments, the first ultraviolet light unit 132 and the second ultraviolet light unit 134 may also be ultraviolet mercury lamps. Since the ultraviolet light emitting diode is of high power, high heat is generated during operation. In order to reduce the temperature of the ultraviolet light emitting diode, the substrate of the ultraviolet light module 130 can be an aluminum substrate (MCPCB) to quickly dissipate heat.

In addition, FIG. 6 is an internal schematic diagram of the autonomous mobile device of FIG. 1. Please refer to FIG. 6, in this embodiment, the autonomous mobile device 100 further includes a first heat sink 160, a second heat sink 162 and a fan 164. The first heat dissipation member 160 is disposed in the body 110 and thermally coupled to the first ultraviolet light units 132. The second heat dissipation element 162 is disposed in the body 110 and thermally coupled to the second ultraviolet light units 134, and the second heat dissipation element 162 is obliquely disposed beside the first heat dissipation element 160 to correspond to the inclined second ultraviolet light unit 134. The fan 164 is disposed in the body 110 and is located beside the first heat sink 160 and the second heat sink 162 to achieve the effect of sharing the airflow. The air flow blown by the fan 164 can flow along the channels of the first heat sink 160 and the second heat sink 162 on the fins, and has a good heat dissipation effect.

In summary, the autonomous mobile device created by the new model is provided with an ultraviolet light module at the bottom of the body, which can have a sterilization effect. The bottom cover of the autonomous mobile device is detachably arranged at the bottom of the body. When the bottom cover is not installed on the body, the autonomous mobile device can move autonomously and act as a sterilization robot. When the bottom cover is installed on the body, the bottom cover shields the wheels and exposes the ultraviolet light module and the bottom distance sensor, which can be used as a handheld sterilization device. In addition, the bottom distance sensor of the autonomous mobile device can sense the distance between the body and the object below. When the distance exceeds the preset value, it may be in an abnormal use state. The control module turns off the UV module to avoid Ultraviolet light hits the human body by mistake, and has a good safety protection mechanism.
