Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model preferred embodiment;
Fig. 2 is the block scheme of the utility model preferred embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As depicted in figs. 1 and 2, one is rear mounted wears eyesight protector, comprise housing 1, housing is U-shaped, range finding probe 2 is respectively equipped with in two terminations of housing, be provided with processor 3, warning device 4, switchgear 5 and power supply 6 in housing, range finding probe 2 and warning device 4 are electrically connected with processor 3 respectively, and power supply 6 is electrically connected with processor 3 by switchgear 5; Housing 1 is provided with ear-hang 11 at corresponding auricle place, and range finding probe 2 is placed on user two sides.Prior art detection range is between frons and read-write object, and there is certain deviation the position of frons and eyes, and has larger deviation with the difference of everyone wearing position, causes producing measuring error.And range finding probe 2 is arranged on two sides by the utility model, substantially coordinates with the auricle of user with the completely heavy merga pass ear-hang of eye locations and the position of probe 2 of finding range is fixed.
As shown in Figure 1, described housing 1 coordinates pinna shape to bend by ear-hang 11 place.Housing 1 coordinates pinna shape to bend can to efficiently solve the wearing comfort degree problem of this kind equipment in conjunction with ear-hang 101.
Be provided with posture inductor 7 in described housing 1, posture inductor 7 is electrically connected with processor 3; Posture inductor 7 is gravity sensor or gyroscope.Posture inductor 7 detects the angle of inclination of wearer's head.Adopt gravity sensor or the angle of inclination of gyroscope to wearer's head to measure, if exceed setting range, report to the police.
Described range finding probe 2 is infrared inductor or laser inductor.Range finding probe 2 detects eyes and the distance of watching object.By infrared ray sensor detection eye and the distance of watching object attentively, when its distance is shorter than setting range, report to the police.
As shown in Figure 2, described warning device 4 comprises hummer 41, vibrating motor 42, and hummer 41, vibrating motor 42 are electrically connected with processor 3 respectively.Hummer 41 sounding alarm reminds wearer to note reading distance, time, posture etc.In the occasion that inconvenience is sounded, vibrating motor 42 adopts the mode of vibration housing to remind wearer to note reading distance, time, posture.
As shown in Figure 2, described in the device 5 that opens the light comprise gauge tap 51, inductive switch 52, gauge tap 51 is connected with inductive switch 52; Inductive switch 52 comprises distance perspective inductive switch 521 and light sensing switch 522.Distance perspective inductive switch 521 and light sensing switch 522 can be arranged on the corresponding postauricular position of housing.Also the medial surface of housing 1 close to human body can be arranged on.The reading time of record wearer opened by distance perspective inductive switch 521 and light sensing switch 522 after connecting.Judge the time after human body wearable device by proximity transducer, exceed Preset Time and carry out warning reminding.Inductive switch 52, can powered-down automatically when long-time (the concrete time can set) detects that equipment is not worn on head, makes equipment be in power down mode, to extend charging service time afterwards.
