Abstract

The utility model belongs to the field of automobile parts and particularly relates to a structure integrating a sliding ring base and a lower protecting cover. The structure integrating the sliding ring base and the lower protecting cover comprises the sliding ring base and the lower protecting cover. The sliding ring base and the lower protecting cover are integrated. Therefore, the problems of fussy process generated by simple manufacturing and assembly and horn trigger fault caused by an installing error are avoided, the production process is greatly shortened, the production cost and production period of an enterprise are reduced, and meanwhile, the potential safety hazard is also avoided.

Description

The integral structure of a kind of slip ring base and following protecting cover

Technical field

The utility model belongs to the auto parts and components field, is specifically related to the integral structure of a kind of slip ring base and following protecting cover.

Background technology

Bearing circle is by controlling manually and so as to handling the colyliform device of travel direction such as automobile, steamer, aircraft, loudspeaker then are the acoustic signal devices of automobile, in the driving process of automobile, chaufeur sends essential audible signal with regulation as required, warning pedestrian and cause that other vehicles note, guarantee safety traffic, also be used to urge row simultaneously and transmit signal.Bearing circle comprises outer edge, center disk body and the connecting arm that is used to connect both, and the trigger element of loudspeaker then is arranged in the container cavity of center disk body, and its container cavity is formed naturally by following protecting cover usually.Aspect drawing for the wiring of trigger element, in the existing steering wheel assembly process, all be to utilize the slip ring base of producing separately, earlier the slip ring base is fixed in down on the protecting cover, settle the metal connection annulus more thereon, the metal connection annulus is connected with the terminals of trigger element, thereby the energizing signal that guarantees bearing circle its trigger element when rotating can be passed to the car body circuit until the loudspeaker place by the metal connection annulus all the time, yet, there is following defective in above-mentioned structure: at first, existing steering wheel is when producing assembling, its slip ring base all needs to make separately with following protecting cover, finally realize both reliable fit by a series of mould and operation again, operation is complicated and use mould more in said process; Secondly, because the affixed strictness location that needs between slip ring base and following protecting cover, yet the error in the installation process is inevitable again, in case this has just caused both error to occur in the location, bearing circle goes wrong with contacting between bearing circle bonded assembly metal connection annulus and car body circuit when rotating, after the appearance bearing circle turns to certain position, loudspeaker trigger fault, cause its reliability to reduce, and cause potential safety hazard.

Summary of the invention

The integral structure that the purpose of this utility model provides a kind of slip ring base and following protecting cover can reduce production process greatly, guarantees that simultaneously the loudspeaker reliable trigger is stable.

For achieving the above object, the utility model has adopted following technical scheme: the integral structure of a kind of slip ring base and following protecting cover, comprise slip ring base and following protecting cover, described slip ring base is the integral type structure with following protecting cover, and described slip ring base and following protecting cover are for once injection molded.

The beneficial effects of the utility model are: after adopting said structure, the loudspeaker that operation is loaded down with trivial details and installation error causes that can remove above-mentioned independent making and assembling from and produce trigger the problem of fault, not only reduced its production process greatly, reduce enterprise's productive costs and cycle, the generation of also having stopped potential safety hazard simultaneously.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the semisectional view of Fig. 1 structure.

The specific embodiment

The integral structure of a kind of slip ring base and following protecting cover comprises slip ring base 10 and following protecting cover 20, and described slip ring base 10 is constructed for integral type with following protecting cover 20, shown in Fig. 1-2.

Said structure in actual use, because slip ring base 10 and 20 of following protecting covers have constituted reliable fit, the loaded down with trivial details problem of operation that can remove from independent making slip ring base 10 also to assemble and produce with following protecting cover 20, simultaneously, because integral type structure, naturally constituting affixed rigidity between between slip ring base and following protecting cover cooperates, also just avoided the generation of installation error, and then reliably touching between assurance metal connection annulus and car body circuit, the loudspeaker reliable trigger is stable, not only reduced its production process greatly, reduced enterprise's productive costs and cycle, the generation of also having stopped potential safety hazard simultaneously.

Further, described slip ring base 10 and following protecting cover 20 are for once injection molded.

Claims (1)

1. the integral structure of a slip ring base and following protecting cover, comprise slip ring base (10) and following protecting cover (20), it is characterized in that: described slip ring base (10) is the integral type structure with following protecting cover (20), and described slip ring base (10) and following protecting cover (20) are for once injection molded.
