Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment of the present utility model is described in detail in preferred embodiment.
As shown in Figure 1, the utility model provide it is a kind of be capable of the office chair of automatic homing, including be arranged from top to bottom
Seat 1, support column 2 with the chair back and chassis 3 are provided with detection module 4 and motion control mechanism 5, lower section setting on chassis 3
There are multiple castors 6, further includes the ranging baffle 7 and signal emission module 8 being arranged in desk bottom；The signal emission module 8
Emit signal to detection module 4, motion control mechanism 5 controls multiple castors 6 according to the signal of detection module 4 and moves, to band
Office chair is moved to desk direction automatic homing.
The motion control mechanism 5 includes the motor 51 for controlling the movement of castor 6, for controlling 6 moving direction of castor
Steering engine 52, controller 53 and power supply 54, each castor 6 are both provided with the motor 51 being attached thereto and steering engine 52, the controller 53
It is connected with power supply 54, detection module 4, multiple motors 51 and steering engine 52.
The detection module 4 includes range laser radar 41, Bluetooth Receiver 42 and multiple distance measuring sensors, laser ranging thunder
It is arranged on support column 2 up to 41, the vertical range for measuring office chair and ranging baffle 7；First distance measuring sensor 43 and indigo plant
The position of face seat opening, the second distance measuring sensor 44 and third distance measuring sensor 45 is arranged on chassis 3 in tooth receiver 42
Positioned at the both sides of the first distance measuring sensor 43 and it is separated by 90 degree with the first distance measuring sensor 43, first distance measuring sensor 43,
Second distance measuring sensor 44 is used to measure at a distance from front and ranging baffle 7 with third distance measuring sensor 45；Signal emits
Module 8 includes that bluetooth transmitters 81, the bluetooth transmitters 81 and Bluetooth Receiver 42 measure office according to the strong and weak of Bluetooth signal
Chair is at a distance from bluetooth transmitters 81.
In addition, being provided with pressure sensor 11 in 1 center of seat, chair back center is provided with human body infrared inductor 12,
The pressure sensor 11 for detect the top of seat 1 whether someone, which is in front of the chair back for detecting
The signal detected is sent to motion control mechanism 5 by no someone, the pressure sensor 11 and human body infrared inductor 12, this
Sample, after user leaves office chair, office chair can start automatic homing operation.
First distance measuring sensor 43, the second distance measuring sensor 44 and 45 preferred laser ranging of third distance measuring sensor sensing
Device, 51 preferred direct current generator of motor, the microcontroller of the preferred model STM32F103 of controller.The castor 6 of office chair is preferably provided with
There are four, and it is separated by 90 degree of settings two-by-two, the first distance measuring sensor 43, the second distance measuring sensor 44 and third distance measuring sensor 45
45 degree of settings are differed with two adjacent castors 6 respectively, in this way, facilitating distance measuring sensor detecting distance, are also convenient for motion control
Mechanism 5 adjusts the differential of castor 6, so that the seat opening face desk playback of office chair.
The operation principle of the utility model is as follows：
First, after user leaves office chair, pressure sensor 11 and human body infrared inductor 12 are detected simultaneously by nothing
People's signal, and this unmanned signal is sent to the controller 53 of motion control mechanism, open office chair returning to desk direction
Bit manipulation.
Secondly, range laser radar 41 starts to be scanned observation to office chair ambient enviroment, obtains by 361 apart from degree
Corresponding range information, is transformed to the coordinate points in coordinate system, is separated to coordinate points by the range information that magnitude is constituted, and
It is fitted with line segment, establishes the coordinate system centered on office chair, and build map.According to the power of Bluetooth signal, pass through
The Bluetooth Receiver 42 that is arranged on office chair and the bluetooth transmitters 81 in desk bottom are set, measure office chair and bluetooth
The distance a1 of transmitter 81, and this distance and the range information in structure map are compared, judge that positioning is completed in office chair position,
It is calculated again with office chair present position coordinate by the coordinate of bluetooth transmitters 81 vertical between office chair and ranging plate washer 7
Distance d.
Again, the distance a2 that ranging baffle 7 is arrived in its front is measured using the first distance measuring sensor 43, if a2 is equal to d,
The seat opening face desk for illustrating office chair, using the cosine law, the straight line where calculating distance a2 and vertical range d institutes
Angle theta between straight line, this angle are each castor moving direction angle, and each castor is controlled by motion control mechanism 5
It is linearly moved according to this moving direction angle, to drive office chair to playback to desk direction；If a2 is not equal to d,
Then illustrate the seat opening not face desk of office chair, equally, using the cosine law, calculates straight line where distance a2 and hang down
Angle between straight line where the directly angle β between straight line where distance d, and the straight line where distance a1 and vertical range d
α, and it is each castor moving direction angle to be the difference θ that subtraction obtains to two angles, is controlled by motion control mechanism 5
It makes each castor linearly to move according to this moving direction angle, to drive office chair to playback to desk direction.
Finally, when office chair is close to desk, the second distance measuring sensor 44 and third distance measuring sensor 45 are started to work,
Measure the distance that ranging baffle 7 is arrived in its front, if two apart from equal, illustrate the seat opening face office of office chair
Table moves at this point, office chair continues to playback to desk direction, until returning to initial position；If two apart from unequal, are said
The seat opening not face desk of bright office chair, then pass through differential steering by motion control mechanism, adjust two opposite feet
The speed for taking turns corresponding direct current generator, until apart from equal, makes the seat of office chair be open so as to adjust the office chair direction of motion
It is moved to face desk, then office chair continues to move, until returning to initial position.
The utility model by the motor and steering engine that are arranged on castor, in conjunction with range laser radar, bluetooth transmitters and
Bluetooth Receiver, multiple distance measuring sensors, using the cosine law, motion control mechanism plans playback path automatically, completes office
Operation of the chair to desk automatic homing, you can allow rambling office to automatically become clean and tidy orderly, and without artificial behaviour
Make, use manpower and material resources sparingly financial resources, meanwhile, easy to operate, securely and reliably, strong applicability meets the trend of development in science and technology, adapts to city
The demand of field has vast potential for future development.
Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
These are merely examples, under the premise of without departing substantially from the principles of the present invention and essence, can be done to these embodiments
Go out various changes or modifications, therefore, the scope of protection of the utility model is defined by the appended claims.
