Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Under be classified as each component model and effect of this case:

Servo motor: using the servo motor of the model 57BYGH5330 of Su Jie production, servo motor (servo Motor) refer to the engine for controlling mechanical organ operating in servo-system, be a kind of indirect speed change gear of subsidy motor.

Pressure sensor: using the pressure sensor of the model 3967251 of cqkms production, pressure sensor (Pressure Transducer) is to experience pressure signal, and can be converted into can be used by pressure signal according to certain rule Output electric signal device or device.

By those skilled in the art, the power supply that electricity pieces all in this case are adapted to it is attached by conducting wire, and Suitable controller and encoder should be selected according to the actual situation, to meet demand for control, specifically connect and control and is suitable Sequence, should be with reference in following working principles, and successive job order is completed to be electrically connected between each electricity piece, detailed connection means, It is following mainly to introduce working principle and process for techniques well known, no longer electrical control is explained.

Embodiment: 1-4 is it is found that a kind of vacant seat prompt system in library, specifically includes that chair 1, chair with reference to the accompanying drawings Open up fluted on the chair back of son 1, and groove lower wall surface offers threaded hole, and induction part, chair are mounted on the seat of chair 1 Prompting part is mounted in 1 chair back groove；

Induction part comprising: rib 2, the identical limited block 3 of a pair of of structure, pressure sensor 4, two are identical to structure Spring 5 and pressing plate 6, connection relationship is as follows；

Rib 2 is fixedly installed in the seat upper surface of chair 1, and a pair of of limited block 3 is fixedly installed in table on the seat of chair 1 At left and right sides of face, and be located in rib 2, pressure sensor 4 is installed on the seat of chair 1, and be located at a pair of of limited block 3 it Between, two pairs of 5 one end of spring are fixedly installed in the seat upper surface of chair 1 respectively, and are located at 4 surrounding of pressure sensor, pressing plate 6 with Two pairs of 5 other ends of spring are fixedly connected, and are located in rib 2；

It can be seen from the above, making pressing plate 6 drop to a pair of of limited block 3 by the effect of pressure when someone sits on pressing plate 6 Upper surface, since the height and 3 height of limited block of pressure sensor 4 are consistent, pressure sensor 4 also shares the weight of a part, The signal sensed is transferred to controller by pressure sensor 4 as electronic signals, and when people leaves pressing plate 6, pressing plate 6 is two It is resetted under the action of team's spring 5, pressing plate 6 also leaves pressure sensor 4, and pressure sensor 4 is by the signal of receiving with electric signal Form is transferred to controller；

Prompting part comprising: servo motor 7, gear 8, screw rod 9, bearing 10, support plate 11 and warning light 12 connect It is as follows to connect relationship；

Servo motor 7 is placed in the chair back groove of chair 1, and gear 8 is fixedly installed in servo motor 7 and drives on end, silk A part of spiral of bar 9 is installed in the threaded hole of chair back groove of chair 1, and is engaged with gear 8, the fixed peace of the inner ring of bearing 10 Loaded on screw rod 9, support plate 11 is fixedly linked with bearing 10, and warning light 12 is installed on 11 upper surface of support plate；

It can be seen from the above, starting servo motor 7, servo motor 7 drives end rotation that the gear 8 being firmly connected with it is driven to revolve Turn, at the same time, the screw rod 9 engaged with gear 8 starts turning, and drives support plate 11 thereon to rise or decline, to make 11 warning light 12 of support plate is installed on to rise or decline；

In conclusion when people accomplishes the pressing plate 6 on chair 1, making pressing plate by gravity when someone uses library seats 6 are pressed on limited block 3, since 4 height of pressure sensor is consistent with 3 height of limited block, have pressure sensor 4 and limited block 3 total With the weight of support human body, when pressure sensor 4 detects weight, warning light 12 is controlled by controller and is extinguished, and under It drops in the chair back groove of chair 1, when people leaves seat, under the action of spring 5, pressing plate 6 is made to leave pressure sensor 4, Pressure sensor 4 can't detect gravity, controls the warning light 12 in groove by controller and lights, and rising to can be for people Height easy to find, due to the effect of telescopic rod 15, since friction is gone here and there when can prevent from rising from groove in support plate 11 It is dynamic, and make not dropping into groove when decline, and when user needs the short time to leave, it is placed on desk The printed words of " someone herein " prevent someone from seeing that warning light 12 lights herein and accidentally account for seat.

Preferably, further, be mounted with de-noising pad 13 at the chair leg of chair 1: the de-noising pad 13 is used for The noise generated when reducing mobile chair 1.

Preferably, further, the height of pressure sensor 4 is consistent with the height of limited block 3.

Preferably, further, rib 2 is rectangular frame.

Preferably, further, 6 sectional area of pressing plate and 2 inside area equation of rib.

Preferably, further, 6 upper surface of pressing plate is mounted with neonychium 14: the neonychium 14 is for protecting Human body is equipped with telescopic rod 15 between support plate 11 and groove: the telescopic rod 15 prevents support plate 11 from shaking for limiting.
