Embodiment
Referring to Fig. 1, eyeshield attention device of the present utility model comprises: 20 liang of major parts of main frame 10 and range sensor.
This main frame 10 is made and the base 11 and the loam cake 12 that can cooperatively interact constitute by any appearance of tool as shown in Figure 1 to Figure 3, at base 11 and 12 of loam cakes and be embedded with a circuit board 13; This base 11 forms the accommodation space 111 of shape depression in little centre, so that installing of battery 14 to be provided, then the right position is formed with several reference columns 112 around this accommodation space 11, and in wherein detain a side be provided with a dead slot 113 for an ac power plug seat 15 build-ins in interior, dead slot 113 sides then be formed with in addition a breach 114 leads bury underground by, in addition, the above-mentioned appearance space 111 of putting is provided with a lid 115 sealings again; Loam cake 12 is for having the outward appearance of special type design, and the nearly central authorities of inner face form several short columns 121 of projection, and by screw with circuit board 13 in conjunction with the location, be provided with one group in inner face central authorities again and screw togather post 122 and several open-works 123 relatively, use in conjunction with cresset display module 136; In addition, be provided with several column 124 corresponding above-mentioned reference columns 112 in the right position in addition, wear through screw and make base 11 and firm being combined into one of loam cake 12 energy at loam cake 12 nearly peripheries.
One range sensor 20, utilize lead to be connected with system processor 131 on the circuit board 13, there is a sliding seat 21 can make any axial rotation, and can arrange the devil that can bind mutually at sliding seat 21 back sides and glue pattern, and wherein Yi Bufen devil is sticking can be fixed on ad-hoc location according to user's demand, is beneficial to range sensor 20 fixing really.
According to said structure, as shown in Figure 5, when reality is implemented to use, the main frame 10 of the utility model eyeshield attention device is placed appropriate location on the desktop, simultaneously that range sensor 20 usefulness devils are sticking and be fixed in the edge end face of desktop towards user's direction, so that this range sensor 20 can correspond to the chin position (this distance is the gauged distance of rectifying sitting posture) of user's head up and lead is located really with the line clip, and reach the neat appearance effect, so, before being seated at desk, the user reads, when operation such as writing, in case during the luminance shortage of integrated environment, photoresistance 132 just can be responded in good time and the message data is back to system processor 131, inform that to impel caution circuit 135 triggers the broadcast that software I C carries out the caution music, and discharge by hummer, to remind the present ambient brightness deficiency of user; When user's sitting a period of time, if abnormal sitting posture is true, (this variation had exceeded default gauged distance when the distance that makes its eyes look at object straight changed, at this moment, range sensor 20 just reacts in good time and the detection data is returned, to system processor 131, and impel caution to inform that circuit 135 triggers software I C equally, and discharge the not enough musical sound of default distance, to make the user learn at present for really making the visual range deficiency because of abnormal sitting posture, probably can damage, should improve present situation at once; Moreover, before the user continues to be seated at desk, at this moment, if the fragmentary works time one default in the time controller 134 arrives, at once with data return system controller 131, trigger caution simultaneously and inform that circuit causes the caution music of time of having a rest, remind should stand up activity or have a rest of user, after this attention device was reissued the caution music that finishes of having a rest, the user continued operation before can returning desk.
Eyeshield attention device of the present utility model, circuit board 13 wherein removes the internal DC powering mode that can directly utilize installing 9V battery 14 in its base 10 central accommodation spaces 111, also can see through the external AC powering mode that ac power plug seat 15 articulates general household electricity, and the convenient utilization benefit of tool diversification, and under the DC powering mode that uses battery 14, in case during power shortage, via 133 inductions of weak electricity measuring device, also can trigger the caution sound music, remind the user to deal with through system processor 131.
Fig. 6 shows and can implement a circuit of the present utility model, only provides those skilled in the art to realize reference of the present utility model according to this circuit, rather than is used for limiting structure of the present utility model.Wherein, U1 is a system processor 131.
Because the eyeshield attention device of the utility model particular design, using eye distance from not enough, ambient brightness, and even under the situations such as overlong time, all can remind the situation that the user has produced is enough to endanger eyes by the in good time different caution sound musics that send, should be improved immediately, thus, for the general user who grows up, particularly minor child will help it to form correct sitting posture and good being accustomed to eye.
The above is specific embodiment of the utility model and the principle used, rather than to concrete qualification of the present utility model.Therefore various modifications and the improvement of doing according to above-mentioned principle all falls into protection domain of the present utility model.
