Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：
As shown in Figs 1-4, a kind of Chain cushion adjusting apparatus based on acceleration induction, mainly by support plate 8, acceleration
Sensing device, Chain cushion adjusting apparatus.
Such as Fig. 1, acceleration sensing is mainly made of outer box 1, spring 2, induction metal plate 3, sheet iron 4, steel ball 5.
Outer box 1 are process by nonconducting smooth rigid plastic sheet, have certain intensity and wearability.Spring 2 is mark
Quasi- part, spring rate is determined according to the quality of steel ball and setting maximum acceleration value, and spring one end is fixed on the inside of outer box 1, one
4 middle of sheet iron is fixed at end.Induction metal plate 3 uses copper foil, is fixed on the both sides of outer box 1, close to the side of steel ball 5
Be close to 1 side wall of outer box, and farther out side then bullet internally so that contact is conductive smoothly.Sheet iron 4, steel ball 5 and 1 inner wall of outer box
Contact smooth.Induction metal plate 3 passes through 6 connecting wire 7 of sheet metal binding post.
Such as Fig. 2, Chain cushion dip angle regulating device is mainly by support plate 8, solenoid feed terminal 9, electromagnetic coil 10, tooth
Bar 11, cushion fixation tablet 12, rotation bracing strut 13, rotation axis 14, gear 15, moving iron core 16, seat lower carriage 17 form.
Electromagnetic coil 10 and moving iron core 16 are all standard components, are all located in the guide groove in support plate 8, moving iron core 16
It is fixedly connected with rack 11, and support plate 8 separates rack 11 and electromagnetic coil 10, while moving iron core 16 is in electromagnetic force
When being moved under effect along guide groove, rack also slides in support plate 8 at the same time.Seat, which is fixed tablet 12 and fixed with cushion 18, to be connected
Connect, there is some strength, while rotation axis 14 rotates, cushion 18 can and then turn an angle.Stent 17 is fixed on
The right side of seat, is just cast by alloy and formed, and has some strength, and rotation axis 14 is connected with stent 17 by rolling bearing,
Ensure the flexibility that rotation axis 14 rotates.
It is the scheme of installation that whole device combines with seat such as Fig. 3.Acceleration sensing inclines with Chain cushion
The left side that angle regulating device is installed on seat is fixed, and two of the extraction of sheet metal binding post 6 in the outer box 1 of acceleration sensing
Root conducting wire 7 is connected serially to by solenoid feed terminal 9 in the power supply circuit of electromagnetic coil 10, because whole device is fairly simple, ruler
It is very little smaller, and need not too big installation space, while do not influence driving of the driver to vehicle.
It is the circuit diagram of whole device such as Fig. 4, electromagnetic coil is connected in series with acceleration sensing, while in electromagnetism
The both ends of coil are also connected in parallel with a capacitor.When acceleration sensing connects circuit, electromagnetic coil 10, which is powered, produces electromagnetic force,
Capacitance starts to charge up at the same time, and when acceleration sensing disconnecting circuit, capacitance starts to discharge, and can still make electromagnetic coil 10
Electromagnetic force is produced, holds moving iron core 16.
In summary introduce, whether acceleration sensing closes according to the size decision-making circuit of current vehicle acceleration,
Whether solenoid is given.The energization of electromagnetic coil produces electromagnetic force, while moving iron core moves in guide groove, and
The gear that it is fixedly connected also and then moves, then by rack geared, straight-line displacement is changed into the rotation of seat, is realized
By automobile cushion Inclination maneuver to suitable position.After capacitance discharge off, electromagnetic coil power-off, automobile seat cushion is in gravity
Effect is lower will to recover original state again.
