The sensing device that is used for assembling chair angle regulator
Technical field
The present invention relates to seat angle adjustor, particularly a kind of sensing device for assembling chair angle regulator, this device is used for the assembling of seat angle adjustor core members, accurately the position of perception working shaft.
Background technology
Present automotive seat have the function of freely adjusting the chair back, and when people pressed the handle of seat angle adjustor and the chair back applied certain external force, the chair back just can recede to reach the angle of back-rest of people's demand; And when people need to recall to initial state with the chair back, only need again press the handle of seat angle adjustor and keep the chair back to be the stressed state of nature, the chair back just can be replied.
Seat angle adjustor generally is comprised of chair back gusset piece, seat support gusset piece, core members, handwheel or regulating handle etc., and core members is connected with the seat support gusset piece with chair back gusset piece respectively.In the practical application, necessary parts need to be installed in core members, installing component needs an operator's station, is placed with the device of many Various Functions on the operator's station; Parts are connected to the working shaft end, and during installing component, the control lever on the rotation work axle makes working shaft rotation and translation, and the parts of working shaft end are embedded in the core members of seat angle adjustor, and the shaft-cup of the working shaft other end is translation and rotation also; The rotating operation bar is returned to initial position with it, and then working shaft is returned to initial position, and shaft-cup also returns to initial position.In practical operation, parts are embedded the core members of seat angle adjustor after, operating personal may forget device is returned back to initial condition that this can reduce the instrument life-span; When some fault (can't get back to initial position such as device) occurs machine, method with range estimation and estimation can't be confirmed this fault, therefore be necessary to design a kind of sensing device, this sensing device should be able to determine that working shaft is in initial position translation or rotation still occur.
Summary of the invention
The object of the present invention is to provide a kind of sensing device for the assembling of seat angle adjustor core members, the accurate perception working shaft position of energy.
For achieving the above object, the technical solution adopted in the present invention is: a kind of sensing device for assembling chair angle regulator, this device comprises stay bearing plate, working shaft, shaft-cup, telltale, shaft-cup is positioned at the work the tip of the axis, translation or rotation can occur in working shaft, it is characterized in that: also comprise sensor board, sensor, sensor block; Sensor board is placed on the stay bearing plate, and sensor is positioned on the sensor board, and sensor block is connected with the shaft-cup center; Sensor board and sensor are positioned at the sensor block below, and sensor is relative with the sensor block position; The signal of sensor output is shown by telltale.
Sensor block is divided into two parts, and a part is connected with the shaft-cup center and vertically arranges, and another part is sensitive surface, and sensitive surface is horizontally disposed with and is relative with sensor station.Along with rotation or the translation of working shaft, sensor block will rotate or translation along with working shaft, this moment sensor block sensitive surface will occur translation leave sensor directly over or rotate with sensor and be an angle.This sensing device changes the different signal of output by the relative position of sensor and sensor block.
Beneficial effect of the present invention: captive joint with working shaft by sensor block, accurately perception working shaft position; During practical operation, parts are embedded the core members of seat angle adjustor after, operating personal may forget device is returned back to initial condition, this can reduce the instrument life-span, this sensing device can be reminded operating personal, thereby has prolonged the instrument life-span; When some operating troubles (can't make working shaft rotation or mobile, device can't get back to initial position such as control lever) appears in instrument, this sensing device can be discovered.
Description of drawings
Fig. 1 is front view of the present invention;
Fig. 2 is lateral plan of the present invention;
Wherein, 1 stay bearing plate, 2 working shafts, 3 shaft-cups, 4 sensor blocks, 5 sensor boards, 6 sensors, 7 sensitive surface.
The specific embodiment
Figure is the preferred embodiments of the present invention, and the invention will be further described below in conjunction with accompanying drawing: wherein, and 1 stay bearing plate, 2 working shafts, 3 shaft-cups, 4 sensor blocks, 5 sensor boards, 6 sensors, 7 sensitive surface.
Referring to Fig. 1, be used for the sensing device of assembling chair angle regulator, comprise that stay bearing plate 1, working shaft 2, shaft-cup 3 are positioned at the end of working shaft 2, translation or rotation can occur in working shaft 2, it is characterized in that: also comprise sensor board 5, sensor 6, sensor block 4; Sensor board 5 is placed on the stay bearing plate 1, and sensor 6 is positioned on the sensor board 5, and sensor block 4 is connected with shaft-cup 3 centers; Sensor board 5 and sensor 6 are positioned at sensor block 4 belows, and sensor 6 is relative with sensor block 4 positions; The signal of sensor output is shown by telltale.
As shown in Figure 2, sensor block 4 is bending plates, and sensor block 4 is divided into two parts, and a part is connected with shaft-cup 3 centers and vertically arranges, and another part is sensitive surface 7, and sensitive surface 7 is horizontally disposed with and is relative with sensor station.Along with rotation or the translation of working shaft 2, sensor block 4 will rotate or translation along with working shaft, this moment sensor block 4 sensitive surface 7 will occur translation leave sensor 6 directly over or rotate with sensor 6 and be an angle.
This sensing device changes the different signal of output by the relative position of sensor 6 and sensor block 4, when sensor 6 be positioned at sensor block 4 under and sensitive surface 7 and sensor 6 when parallel, the signal of sensing device output is " working shaft 2 is positioned at initial position, and translation or rotation do not occur "; When sensor 6 not under sensor block 4 or sensitive surface 7 when not parallel with sensor 6, the signal of sensing device output is " working shaft 2 is not at initial position, and translation or rotations occur working shaft 2 "; When sensor 6 not under sensor block 4 and sensitive surface 7 when not parallel with sensor 6, the signal of sensing device output is " working shaft 2 is not at initial position, and translation and rotations occur working shaft 2 ".
During practical operation, parts are embedded the core members of seat angle adjustor after, operating personal may forget device is returned back to initial condition, this can reduce the instrument life-span, this sensing device can be reminded operating personal, thereby has prolonged the instrument life-span; When some operating troubles (can't make working shaft move, install such as control lever and can't get back to initial position) appears in instrument, this sensing device can be discovered.
More than show and described groundwork of the present invention and principal character and advantage of the present invention.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
