Title of invention:
A ROTARY-TYPE HANDLEBAR SWITCH
APPLICANT:
VARROC ENGINEERING LIMITED
An Indian Company
Having address as:
L-4, MIDC Waluj, Aurangabad 431136, Maharashtra, India
The following specification particularly describes the invention and the manner in which it is to be performed.
TECHNICAL FIELD
Present disclosure generally relates to field of automobiles. Particularly, but not exclusively, the present disclosure relates to a handlebar switch or a control switch in two-wheeler or three-wheeler automobiles.
BACKGROUND
The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
Presently, the handlebar of two-wheeler or three-wheeler automobiles comprises numerous handlebar switches/control switches that are mounted on the handlebar switch/switchgear assembly. These switches consist of horn module, headlight module, blinker or winker module, pass or passing module, start module, engine kill module, hazard module, etc.
Conventionally, toggle type mechanism is used in dipper module or engine kill module to operate the knobs. These modules consist of a knob, a housing, a base plate or a cover, rivets being rivetted on the base plate or the cover, and a CPC assembly. The CPC assembly further comprises a contact plate carrier (hereafter referred as CPC), a moving contact, a contact spring, a steel ball, and detent spring. When a knob is operated or moved from one position to another position, the CPC assembly, in turn, moves from one position to the other position of a detent profile provided on the housing and rests there firmly with the help of the steel ball and the detent spring.
In some vehicles, the dipper module and the engine kill module also comprise a third position namely auto-return type. The auto-return movement of knob is achieved by a torsion spring used in switch construction. However, in some switch mechanisms, the torsion spring is not used for the auto-return mechanism, and such elimination of the torsion spring in the toggle type switches may lead to failure such as knob getting stuck at auto-return position. This is mainly due to the uneven force distribution of the spring on the knob, and dust accumulation on the detent profile. The knob getting stuck in the auto-return position is the most frequent failure in the toggle type mechanism having auto-return functionality.
Further, in the conventional switches, contact rivets are rivetted on a base plate. A gap (commonly referred to as arc gap) of 0.3 mm is kept along the circumference of the rivet between a rivet mounting hole on the base plate and the rivet head. The arc gap is kept so that when the contact plate moves from one place to the other, due to difference in the height of the rivet head and the base plate surface, there are chances that there will be some sparking at the time contact make-break leading to carbon deposition on the moving contact dimples as well as on the rivets due to sparking. This leads to inconsistent contact make-break. The sparking and constant use of switch leads to wear and tear of the moving contact dimples and the rivets. Such wear and tear lead to contact path generation between contact rivets which keeps the switch always in on state.
Also, the existing handlebar switch with a rotary-type mechanism fails to provide proper auto-return mechanism and fails to achieve an intermediate position of knob as the knob keeps jumping from the auto-return position to the first position. Therefore, the user may face stickiness in the knob over the time. Further, it is difficult to maintain the contact pressure in rotary type mechanism of the rivetted switch at higher current e.g., more than 10 Amps.
Therefore, there exists a need in the art to provide a rotary-type handlebar switch which overcome the above-mentioned problems and to provide an efficient rotary-type operation through the switch for performing various functionalities of the vehicle.
SUMMARY
The present disclosure overcomes one or more shortcomings of the prior art and provides additional advantages discussed throughout the present disclosure. Additional features and advantages are realized through the techniques of the present disclosure. Other embodiments and aspects of the disclosure are described in detail herein and are considered a part of the claimed disclosure.
In one non-limiting embodiment of the present disclosure, a rotary-type handlebar switch comprises a knob, a housing having a detent profile in an inner portion of the housing. The detent profile comprises a plurality of lock positions and slope portions.
