The utility model content
Technical problem to be solved in the utility model is the defective that overcomes in the background technology, and a kind of mobile robot who is used for the domestic environment monitoring that can fully obtain the external environment video information is provided.
In order to reach above purpose, the technical solution adopted in the utility model is as follows:
A kind of mobile robot who is used for the domestic environment monitoring, include power module, driver module, video module, memory module, wireless communication module, sensor assembly and control module, the camera of described video module is installed on the Height Adjustable camera lifting mechanism.
Damage its motor for fear of the user when manually breaking the camera lifting mechanism off with the fingers and thumb, described camera lifting mechanism comprises the clutch that is used to protect camera lifting mechanism motor.
In prioritization scheme of the present utility model, the camera lifting mechanism comprises the first lifting portion, the second lifting portion and power efferent, the described second lifting portion one end is connected with the first lifting portion by rotating shaft, and the other end of the described second lifting portion links to each other with the power efferent.
Described power efferent comprises motor, gear box, clutch, first gear, second gear and steel wire, and described steel wire one end is fixed in the first lifting portion, and the other end is fixed on the driven wheel.
In order to obtain audio-frequency information, in the described first lifting portion microphone is installed also from the external world.
In order to prevent that camera and extraneous barrier from bumping, also be equipped with in the described first lifting portion and keep away the barrier transducer.
In order to ensure communicating by letter of remote control terminal and mobile robot, wireless communication module can have 3G module and WiFi module simultaneously.
The contrast prior art, the beneficial effects of the utility model are:
The mobile robot who is used for the domestic environment monitoring that the utility model discloses is by being installed in camera a Height Adjustable camera lifting mechanism, so the activity that the mobile robot can be by the camera lifting mechanism is to obtain more sufficient video information from the external world.

Embodiment
Below in conjunction with embodiment and contrast accompanying drawing the mobile robot that the utility model is used for domestic environment monitoring is further elaborated.
Please refer to Fig. 1 to Fig. 5, be a preferred embodiment of the present utility model.
The mobile robot 100 who is used for the domestic environment monitoring in the present embodiment comprises power module, driver module, video module, memory module, wireless communication module, sensor assembly and control module.Power module comprises the battery and the charging inlet 60 of repeatedly charging, is used for providing when mobile robot's 100 work energy; Driver module comprises universal wheel 20 and driving wheel 40, driving wheel 40 comprises two at least, by different motor driven, is used to make mobile robot 100 to move in the working region, universal wheel 20 rotates under the promotion of driving wheel 40, is used to make mobile robot 100 to revolve at random and turns to another direction; Video module is used for obtaining video information from the external world, comprises camera 111 and image pick-up card etc.; Audio-frequency module is used for obtaining audio-frequency information from the external world, comprises microphone 112 etc.; Memory module is used to store video information, audio-frequency information and other information etc.; Wireless communication module comprises antenna 50, be used for carrying out data or instruction exchange with remote control terminal, in the present embodiment, wireless communication module has 3G module and WiFi module simultaneously, therefore network breaks down or can improve communication quality by handover network during signal therein, guarantees the communication between remote control terminal and the mobile robot 100; Sensor assembly comprises and is used to detect the transducer of ground environment and detects mobile robot 100 transducer 20 of obstacle on every side; Control module is used for and above-mentioned each module communication, and carries out relevant action according to the signal feedback control robot 100 of each module.
Please refer to Fig. 3 to Fig. 5, camera lifting mechanism 10 of the present utility model comprises the first lifting portion 11, the second lifting portion 12 and power efferent 13, the first lifting portion 11 is connected by the end of rotating shaft 14 with the second lifting portion 12, and can rotate around the second lifting portion 12, the other end of the second lifting portion 12 is connected with power efferent 13.
Be damaged for fear of camera lifting mechanism 10, in the first lifting portion 11 obstacle sensor be installed, keep away the barrier transducer and preferentially select infrared sensor.Second transducer 114 that comprises the first sensor 113 that is positioned at the first lifting portion end in the present embodiment and be positioned at the first lifting portion surface; in order to protect obstacle lifting mechanism 10; the preferential program setting of obstacle detection is adopted in mobile robot 100 control; just when first sensor 113 or second transducer 114 detect obstacle; even remote control terminal sends the lifting order, mobile robot 100 can not carry out yet.
Power efferent 13 comprises motor 131, gear box 133, clutch 134, first gear 138, second gear 137 and steel wire 132, clutch 134 comprise clutch gear 135 and with the 3rd gear 136 of second gears engaged, first gear 138 has twisted wire wheel 139, fixed form is fixed in the first lifting portion 11 one end of steel wire 132 by screw is fastening etc., and the other end is fixed on first gear 138.First gear 138 in the present embodiment can directly mesh with the 3rd gear 136, and second gear 137 has only gearing, can omit in the present embodiment.
Describe the course of work of the utility model of this enforcement camera lifting mechanism below in detail:
After mobile robot 100 receives the lifting order, motor 131 rotates by the clutch gear 135 drive clutches 134 of gear box 133 with clutch 134, clutch 134 drives second gear 137 by the 3rd gear 136 again and rotates, and then first gear 138 of drive and 137 engagements of second gear rotates, make the 12 upwards liftings of the second lifting portion then, steel wire 131 is taken turns on 139 around twisted wire gradually simultaneously, and then drives the 14 upwards liftings around the shaft of the first lifting portion 11.
After mobile robot 100 received the order that descends, the motion process of each parts of power efferent 13 was opposite with said process.
In addition, because the utility model mobile robot 100 power efferent 13 is equipped with clutch 134, therefore when the user manually broke camera lifting mechanism 10 off with the fingers and thumb, motor 131 can not rotate, thereby can protect motor 131 can not be damaged effectively.
