The specific embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in detail.
As shown in Figure 1, press mechanism aloud and be integrated on the safety airbag casing, press the floating type mechanism 1 that presses aloud that mechanism presses aloud for the two-ply realization of adopting relative motion aloud, realize pressing aloud by the contact of the contact on the two-ply.Top plate 2 is connected with safety air bag, and lower plywood 3 is captiveed joint with steering handwheel 4.Steering handwheel 4 is die cast, and overall construction intensity is good, and is convenient to processing.Captiveing joint between lower plywood 3 and the steering handwheel 4 realizes in the following way:
See that in conjunction with Fig. 2～Fig. 4 the bindiny mechanism of air bag module and steering handwheel comprises: lower plywood 3, steering handwheel skeleton 4.It is 3 that lower plywood 3 has among a plurality of torsion spring 31(figure), a plurality of knock hole 33, a plurality of cushion 32, steering handwheel skeleton 4 has a plurality of barbs 41, a plurality of registration mast 43, a plurality of boss 42, torsion spring 34, cushion 32 are captiveed joint with lower plywood 3, registration mast 43, barb 41, boss 42 are captiveed joint with steering handwheel skeleton 4, torsion spring 31 and barb 41 clasp joints, registration mast 43 inserts knock hole 33 and is mated, and boss 42 is fitted with cushion 32.Number and the position of torsion spring 31, cushion 32, knock hole 33 can change as required, as long as make the integral structure stress equalization.
The two ends of torsion spring 31 and lower plywood 3 are fixing, the middle part of torsion spring 31 has snap ring 311, the via hole 36 that snap ring 311 passes lower plywood 3 cooperates with the driving surface 411 of barb 41, the via hole 36 that snap ring 311 passes lower plywood 3 is along the driving surface 411 that catches on barb 41 after the entering surface 412 of barb 41 enters, pressurized when snap ring 311 contacts with entering surface 412.The spring silk 312 at torsion spring 31 two ends can pass through the mode such as welding, riveted joint and lower plywood 3 is fixing, preferably, two ends spring silk 312 bendings of torsion spring 31 are by the hole of lower plywood 3, simultaneously the top local flange 35 of the lower plywood 3 two ends spring silk 312 of withholding torsion spring prevents that torsion spring from tumbling and move, via hole 36 has the flange 34 of location snap ring 311, and flange 34 is bent to form at via hole 36 places for lower plywood 3.
The middle part of torsion spring 31 is bent into snap ring 311, and snap ring 311 passes lower plywood 3, and via hole 36 sizes of lower plywood 3 will satisfy torsion spring 31 with barb 41 clampings and break away from needed stroke requirement.The fixed position of torsion spring 31 on lower plywood 3 is corresponding with barb 41, and the spiral part of torsion spring 31 is placed in the depressed part 37 of lower plywood 3, and depressed part 37 can hold places torsion spring 31, makes the structural stability of torsion spring 31 good, and difficult generation is rocked.
Preferably, barb 41 is distributed in 3,6,9 o'clock of steering handwheel skeleton 4 base plates on the direction, is convenient to drive torsion spring 31 barbs 41 from steering handwheel back side serviceable tool in barb place perforate 45 on the steering handwheel base plate.Barb 41 stretches to steering handwheel inside from the steering handwheel base plate, driving surface 411 tangles snap ring 311, the entering surface 412 of its back is the inclined-plane, entering surface 412 is acute angle with the angle of driving surface 411, pressurized when snap ring 311 contacts with entering surface 412, direction of tilt will mate with the rotation direction of torsion spring 31, and when guaranteeing air bag module is installed, entering surface 412 screws torsion spring.Barb 3 length, shape need to design with snap ring 311 couplings, and barb 41 can hook snap ring 311 easily when guaranteeing assembling, and snap ring 311 is dismantled easily simultaneously.
As shown in Figure 5, lower plywood 3 surface uniforms are distributed with at least four cushions 32, have the boss 42 that matches with cushion 32 on the steering handwheel skeleton 4, when snap ring 311 cooperates with driving surface 411, and cushion 32 compressed distortion.Boss 42 is distributed in around steering handwheel 4 base plates, and boss 42 stretches to steering handwheel inside from steering handwheel skeleton 4 base plates, and boss 42 is hollow structure, and boss 42 height need to cooperate with barb 41, torsion spring 31, cushion 32 to be determined.The position of the cushion 32 on the lower plywood 3 is corresponding with boss, and when barb 41 cooperated with torsion spring 31, boss 42 contacted with cushion 32, cushion 32 pressurizeds.Boss 42 limits lower plywoods 3 along 4 axial the moving of steering handwheel skeleton with barb 41, and when dismantling simultaneously, the elastic force of snap ring 311 barbs 41 rear cushions 32 can make lower plywood 3 and steering handwheel skeleton 4 flick air bag module for convenience detach.
As shown in Figure 6, be evenly distributed with at least two knock holees 33 on the lower plywood 3, registration mast 43 stretches to inside from the steering handwheel base plate, cooperates with knock hole 33 on the lower plywood 3.Registration mast 43 is conical surface hollow structure.Have lining 44 between registration mast 43 and the knock hole 33, preferred, lining 44 has the lining flange 441 for axial location.Knock hole 33 interior mounting bush 44 play the buffer-oriented effect.By cooperating of registration mast 43 and knock hole 33, define lower plywood 3 relative steering handwheel skeleton 4 motions radially, guaranteed that registration is connected reliably with connection.
As shown in Figure 7, during installation, torsion spring 31 is tangled by barb 41, and cushion 32 withstood by boss 42, defines the axial motion of lower plywood 3 relative steering handwheel skeletons 4; The cooperation of knock hole 33 and registration mast 43 defines lower plywood 3 relative steering handwheel skeletons 4 in radially motion.During dismounting, drive torsion spring 31 from steering handwheel bottom serviceable tool torsion spring 31 and barb 41 are broken away from, utilize simultaneously cushion 32 elasticity that safety airbag casing and steering handwheel are broken away from.
Although the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and only be subjected to the restriction of claims, those of ordinary skills can easily make amendment to it and change, but do not leave essence design of the present utility model and scope.
