Detailed description of the invention
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understandSeparate, below in conjunction with concrete diagram, further set forth the present invention.
Referring to Fig. 5 to Fig. 7, the loudspeaker device of a kind of steering wheel providing in figure, comprises steering wheel body1000 and be arranged on four lower contacts 1100 on steering wheel body 1000, be arranged on steering wheel body 1000On upper loudspeaker device assembly 2000 and be arranged on the steering wheel cover plate on loudspeaker device assembly 20003000. Steering wheel body 1000 comprises the frame of handwheel that a metal material is made, four lower contacts 1100Be connected with frame of handwheel.
Referring to Fig. 8, upper loudspeaker device assembly 2000 comprises a horn bracket 2100, is configured in horn bracketFour Compress Springs 2200 on 2100 and upper contact serial connection copper wire 2300. On horn bracket 2100Dispose four Compress Spring installation positions 2110, referring to Fig. 9 to Figure 12, each Compress Spring installation position 2110Inside dispose a Compress Spring positioning tube 2111, and the height of Compress Spring installation position 2110 is higher than compression bulletThe height of spring positioning tube 2111. Compress Spring 2200 is enclosed within on Compress Spring positioning tube 2111, compression bulletMatched in clearance between the internal diameter of the external diameter of spring 2200 and Compress Spring installation position 2110, Compress Spring 2200Internal diameter and the external diameter of Compress Spring positioning tube 2111 between also matched in clearance, in order to make Compress Spring2200 work are more stable, are surrounded with three positioning boss at the root of Compress Spring positioning tube 21112112, Compress Spring 2200 is enclosed within after Compress Spring positioning tube 2111, the bottom of Compress Spring 2200 withInterference fit between positioning boss 2112. In each Compress Spring positioning tube 2111, be provided with under a confessionThe through hole 2113 that contact 1100 is passed, each lower contact 1100 is through corresponding Compress Spring positioning tube 2111In through hole 2113, and the end face of Compress Spring positioning tube 2111 is exposed in the upper end of lower contact 1100.
Referring to Figure 13, upper contact serial connection copper wire 2300 is a complete copper wire, and complete copper wire hasGood elasticity, produces the problem of sound can avoid the collision of loudspeaker the superior and the subordinate time. Upper contact serial connection copper wire 2300On there are four upper contacts 2310, upper contact serial connection copper wire 2300 is serially connected in four upper contacts 2310Together, and each upper contact 2310 is to flatten formation by upper contact being connected in series to copper wire 2300 appropriate locations,Make so upper and lower contact relative position relation more accurate, contact area is large, and electric conductivity is stronger. GinsengSee Fig. 9, Figure 14 and Figure 15, upper contact serial connection copper wire 2300 floats and is arranged on horn bracket 2100,And each upper contact 2310 is all pressed into Compress Spring installation position 2110 by the Compress Spring corresponding with it 2200In the Compress Spring positioning tube 2111 of interior configuration. On horn bracket 2100, dispose six spacing claws2120, these spacing claws 2120 are connected in series copper wire 2300 by upper contact and float and be stuck on horn bracket 2100,And these spacing claws 2120 are configured near of Compress Spring 2200 substantially.
Horn bracket 2100 adopts tapping screw connecting mode, rivet joint mode or the buckle mode of being connected to pacifyBe contained on steering wheel body 1000, these connecting modes all can make horn bracket 2100 and steering wheel originallyCompact connection and Stability Analysis of Structures between body 1000. The present embodiment adopts tapping screw connecting mode to connect,Other two kinds of connecting modes are similar to tapping screw connecting mode, no longer repeat.
Referring to Fig. 5, Fig. 9 and Figure 16, this tapping screw connecting mode is: on horn bracket 2100, joinBe equipped with four staged installing holes 2130, corresponding to each staged installing hole 2130, at horn bracketOn 2100, dispose the positioning convex column 2131 to downward-extension, on steering wheel body 1000, dispose fourLocating hole position 1200 and four locating hole positions 1200,1300, four, tapping screw hole and four tapping screwsHole 1300 is one-to-one relationship and coaxially arranges. When installation, every certain by horn bracket 2100Position hole post 2131 is pressed in the locating hole position 1200 of corresponding steering wheel body 1000 and location, then willTapping screw 1400 is through the staged installing hole 2130 screw-in direction dish bodies on horn bracket 2100In 1000 tapping screw hole 1300.
Between steering wheel cover plate 3000 and horn bracket 2100, adopt buckle mode to connect. Referring to Fig. 6, figure9, Figure 17 and Figure 18, this buckle mode connects and is: on horn bracket 2100, dispose four ellipsesSteering wheel cover plate staged eye-splice hole 2140, staged eye-splice hole 2140 be upper under little elliptical aperture for largeElliptical aperture. Corresponding to each staged eye-splice hole 2140, on steering wheel cover plate 3000, dispose four toThe eye-splice card column 3100 of downward-extension and radial section ovalisation, the bottom minor axis of each eye-splice card column 3100Direction one side disposes outward extending button platform 3110, in the bottom of each eye-splice card column 3100, is provided withSupply the distortion groove 3120 of the bottom strain of eye-splice card column 3110. When needs disassembly direction disk cover plate 3000Time, the tensile force f imposing upwards upwards pulls out steering wheel cover plate 3000, now, and socket card column 3110Button platform 3110 while running into staged plug aperture 2140, distortion groove 3120 provides certain space for socketThere is elastic deformation in the bottom of card column 3110, makes steering wheel cover plate 3000 for convenience detach, as Figure 19 instituteShow, and horn bracket 2100 still remains on steering wheel body 1000, is not easy to damage structural member,Conveniently upper loudspeaker device assembly 2000 is overhauled.
Corresponding to each upper contact 2310, on steering wheel cover plate 3000, dispose four upper to downward-extensionContact compressing post 3200, between the bottom of upper contact compressing post 3200 and upper contact 2310, zero clearance contactsOr Interference contact, oppress Compress Spring 2200 by upper contact 2310 and upper contact serial connection copper wire 2300,Force Compress Spring 2200 in compressive state, therefore, overcome the limiting card because of horn bracket 2100The long-term stress deformation of pawl 2120, thus the problem of Compress Spring 2200 deflection clamping stagnations caused, make assemblingAfter product structure stable, Compress Spring 2200 is difficult for deflection.
After each assembling parts of the loudspeaker device of steering wheel completes, press steering wheel cover plate 3000, by sideDrive the upper contact 2310 and steering wheel body 1000 in upper loudspeaker device assembly 2000 to disk cover plate 3000On lower contact 1100 contact, thereby press loudspeaker aloud.
More than show and described general principle of the present invention and principal character and advantage of the present invention. One's own professionThe technical staff of industry should understand, and the present invention is not restricted to the described embodiments, above-described embodiment and explanationThat in book, describes 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 into claimed model of the present inventionIn enclosing. The claimed scope of the present invention is defined by appending claims and equivalent thereof.
