Abstract
Description
本発明は、ハートカムの作動安定性を図った自動車用のロックＳＷである。 The present invention is a lock SW for an automobile in which heart cam operation stability is achieved.
従来のハートカムは［図１］のように斜面が２ヶ所に設定され、▲お▼（中央Ｖの字）の周囲をロックピンと呼ばれる部品が摺動する構造となっている。 As shown in FIG. 1, the conventional heart cam has two slopes, and a structure called a lock pin slides around the お (center V).
しかし、［図１］の部位▲あ▼と部位▲え▼の間の段差が３段になってしまい、ハートカムを摺動するロックピンはその段差を克服しなければいけないため、［図２］のようにロックピン１に板バネ２で弾性を与え、ハートカム３の段差を吸収している構造になっている。 However, the step between [A] and [E] in [FIG. 1] becomes three steps, and the lock pin that slides on the heart cam must overcome the step, [FIG. 2] In this way, the lock pin 1 is given elasticity by the leaf spring 2 to absorb the step of the heart cam 3.
板バネ等による弾性を与えずにロックピンが安定して摺動することができる構造を実現することを目的とする。 It is an object of the present invention to realize a structure in which a lock pin can slide stably without giving elasticity by a leaf spring or the like.
段差が小さくなればなるほどロックピンは安定して摺動するため、最大段差３段をできるだけ小さくする。
そのために現在は４段２斜面構造［図１］を２段４斜面構造［図３］とする。Since the lock pin slides more stably as the step becomes smaller, the maximum three steps are made as small as possible.
For this purpose, the four-step two-slope structure [FIG. 1] is changed to a two-step four-slope structure [FIG. 3].
そのことにより最大段差が１段になりロックピン自身のたわみのみで摺動できるようになった。 As a result, the maximum step becomes one step, and it becomes possible to slide only by the deflection of the lock pin itself.
板バネやスプリング等の部品が不要となり、部品点数の削減になる。 Parts such as leaf springs and springs are not required, and the number of parts is reduced.
ロックピンの安定性が増したことにより、作動フィーリングも良好となる。 Due to the increased stability of the lock pin, the operating feeling is also good.
ロック機構を兼ね備えた製品に利用が見込める。 It can be used for products that have a locking mechanism.
