Abstract
The utility model relates to a horn switch of an automobile steering wheel, which comprises a restoring spring of a combined switch, a steering restoring ring, a base board of a steering wheel, an upper cover, a lower cover, a microswitch, and a pushing device in the steering wheel. A cutting sleeve is fixedly connected to the base board of the steering wheel by screws. The cutting sleeve is connected with a guide sleeve in a clamping mode, and the guide sleeve is movably connected with an inner sleeve. Four holes in a gland bush of the inner sleeve are sheathed on the four studs under the upper cover of the steering wheel. A linear bearing is arranged between the guide sleeve and the inner sleeve. The four contacts of the inner sleeve are used to press rising and falling rings, and the two contact pins of the steering restoring ring on the combined switch under the lower cover is inserted into the two holes of the lower cover of the steering wheel. The pushing device of the utility model has the advantages of simple structure and low manufacture cost. In particular, a vertically sliding guide sleeve structure of the linear bearing is arranged in the pushing device, which enables the operation to be sensitive and reliable.
Description
One, technical field
The utility model relates to the horn switch on a kind of vehicle steering, belongs to the auto alarm device.
Two, background technology
Vehicle steering loudspeaker conductive structure mostly is the conducting ring friction conduction below the contact on the combined switch or shell fragment and bearing circle at present, press the push contact conducting and make the loudspeaker warning of ringing, this structure is because contact and conducting ring friction, produce friction noise, make conduction bad after the wearing and tearing, need the periodic replacement conducting ring, otherwise loudspeaker are just ineffective.This structure makes complex process, the manufacturing cost height owing to conducting ring is housed and four contacts, spring, support or the like in addition.Chinese patent ZL02232749.5 thrust unit is a connecting rod mechanism, complex structure, poor, the cost height of quality stability.
Three, summary of the invention
The purpose of this utility model is the shortcoming and defect that will overcome the above-mentioned background technology, and provides a kind of simple in structure, the new construction of the horn switch on the vehicle steering of no wearing and tearing, noiselessness, loudspeaker spirit, life-span length.
Technical solutions of the utility model: a kind of vehicle steering horn switch, comprise retracing spring 11, turn to reseting ring 12, base plate 8 in the bearing circle, loam cake 1, lower cover 9, micro-switch 13 is housed on the pedestal of combined switch, is furnished with thrust unit in bearing circle mutually with micro-switch, it is characterized in that described thrust unit structure is: on the base plate on the vehicle steering 8, have the cutting ferrule 6 of four protruding hooks with the screw annular that is fixedly connected, four protruding extend neck shape guide pin bushings 4 that are hooked together of cutting ferrule 6, the guide pin bushing 4 movable interior covers 2 that form by gland with holes and tubular Plastic Parts that connect, on four double-screw bolts that four borehole jacks on interior cover 2 glands are provided with below bearing circle loam cake 1, between guide pin bushing 4 and interior cover 2, linear bearing 5 is housed, in four contacts contact of cover 2 lower ends ring 10 that rises and falls, turn to two of reseting ring 12 to strike the post to insert in two holes of lower covers 9 on the combined switch below the lower cover.Micro-switch is positioned at the below that turns to reseting ring, is fixed on the pedestal of combined switch, will turn to reseting ring to amplify, and makes the following backwardness of its ring that rises and falls can touch micro-switch, and can be pressed onto the below micro-switch is purpose.
Principle of work of the present utility model: press the bearing circle loam cake during operation, reseting ring is fallen, press the micro-switch that is contained on the combined switch, circuit communication, loudspeaker are rung, and realize reporting to the police.Cover resets in unclamp the bearing circle loam cake, retracing spring makes, and loudspeaker do not ring.
The utility model is compared with background technology, and thrust unit is simple in structure, has removed four contacts of the prior art and friction conducting ring, and becoming not have does not have conduction in friction, the noiselessness bearing circle.Thrust unit has the vertical tube-in-tube structure of sliding of linear bearing instead, reliable in action, and sensitieness is strong.
Bearing circle horn switch low cost of manufacture of the present utility model has realized no electric contact in the bearing circle, and is easy to use.
Four, description of drawings
Accompanying drawing is the utility model structural representation
Five, specific embodiments
As shown in the figure: four double-screw bolts are arranged below the bearing circle loam cake 1, four borehole jacks on interior cover bucket 2 iron plates are on four double-screw bolts, be with a linear bearing that matches 5 on the overall diameter of interior cover 2, refilling the overcoat bucket that its internal diameter matches with linear bearing is guide pin bushing 4, four borehole jacks on the guide pin bushing 4 are on four double-screw bolts of bearing circle loam cake 1, four screws 3 are installed are fixed it, make loam cake become cover assembly.On the bearing circle base plate 8 be fixedly connected the fixedly cutting ferrule 6 of four convex annular hooks of four screws.In the circular cavity of resorption of bearing circle lower cover 9 retracing spring 11 is housed, covering the ring 10 that rises and falls, again with four borehole jacks on the base plate 8 on four double-screw bolts of lower cover 9, four holes on the fixing cutting ferrule 6 and four holes on the base plate 8 are aligned, load onto four screws 7, make it to become cap assemblies down.With four slotted eyes on four contacts aligning base plates 8 of the interior cover bucket lower end in the cover assembly, integral body is pressed cover assembly, and four slotted holes of cover bucket 4 bottoms in the cover assembly are stuck in down on four convex annular hooks of cap assemblies fixed card cover.With cover assembly and after descending cap assemblies to install, integral installation turns to two of reseting ring 12 tops to strike the post to be through in two holes of bearing circle lower cover 9 bottoms automobile steering device bar 14 tops, turn to reseting ring 12 enlarged diameter sizes, can be pressed onto the below micro-switch is purpose.Guide pin bushing 4, cutting ferrule 6 and ring 10 materials of rising and falling are POM, use mold injection molding, and interior cover 2 is to become one through mold injection with rammed interior cover gland of δ 1.5mm iron plate and interior cover.
