Description

Technical Field

[0001] The utility model relates to the technical field of automotive parts, and particularly relates to a highly reliable automotive ignition switch. Background Art

[0002] An ignition switch refers to the switch of an ignition system (usually a key is required), which can freely open or close the main circuit of the ignition coil and is also applicable to other electrical circuits. The ignition switch is commonly known as the main switch, the main power switch or the main key. It is the main gate controlling the entire vehicle circuit system and has two types: plug-in type and rotary type.

[0003] Chinese Patent with Publication No. CN220155405U discloses an automotive ignition switch, which relates to the technical field of automotive parts and includes an external fixed shell and an ignition switch housing. The ignition switch housing is arranged inside the external fixed shell. A lock core coaxially arranged with the ignition switch housing is installed on the ignition switch housing. It further includes: two fixing mechanisms arranged on the outer side wall of the external fixed shell, and the external fixed shell and the ignition switch housing are fixed by the fixing mechanisms; a dust-proof mechanism, which includes a dust-proof cover, a fixing rod and a dust-proof plate. A circular hole groove coaxially arranged with the ignition switch housing is opened at the lock head of the ignition switch housing. The dust-proof cover is rotatably installed in the circular hole groove and is coaxially arranged with the circular hole groove. A jack is opened on the dust-proof cover. Both ends of the fixing rod are fixed with first fixing plates, and the fixing rod is located on one side of the jack. The first fixing plates are fixed inside the dust-proof cover. Both ends of the dust-proof plate are fixed with second fixing plates, and through holes are opened on the second fixing plates. The second fixing plates are sleeved on the fixing mechanisms through the through holes. A torsion spring is sleeved on the fixing rod, and both ends of the torsion spring are respectively in contact with the dust-proof plate and the dust-proof cover.

[0004] When the automotive ignition switch described in the above patent is in use, when the key is inserted into the dust-proof cover, the dust-proof plate rotates along the round rod, and the torsion spring applies a reaction force to the dust-proof plate. The rotation of the key drives the dust-proof cover to rotate until the key aligns with the keyhole of the lock core. When the key is withdrawn, the torsion spring covers the dust-proof plate at the jack, thereby preventing dust from entering and realizing the dust-proof function. However, when the key is withdrawn, the dust-proof plate will rub against the key. After long-term use, the dust-proof plate and the key will be worn, reducing the service life. Summary of the Utility Model

It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0032] AsFigures 1 - 5 As shown in the figure, a highly reliable automotive ignition switch in this embodiment includes a connecting member 1 which is fixed on the vehicle. On one side inside the connecting member 1, a lock body 2 is installed. A lock hole 3 is provided on the lock body 2. A retaining ring 6 is sleeved and installed at one end of the connecting member 1. On the inner peripheral wall of the retaining ring 6, second protrusions 7 are provided on all sides, and the second protrusions 7 are away from the connecting member 1. A dust-proof plate 4 is slidably connected inside the retaining ring 6. On the outer side wall of the dust-proof plate 4, a first protrusion 5 is installed, and the first protrusion 5 is adapted to the second protrusion 7. A first concave hole 8 is provided on the back surface of the dust-proof plate 4. A first cylinder 9 is provided inside the first concave hole 8. A second concave hole 10 is provided at the center of one side wall of the connecting member 1. A second cylinder 11 is provided inside the second concave hole 10. A cylinder protrusion 12 is provided at the top of the second cylinder 11. An elastic sheet 13 is installed between the first cylinder 9 and the second cylinder 11. The dust-proof plate 4 slides to the right to cover the lock hole 3 to prevent dust from getting into the lock body 2.

[0033] As Figures 1 - 5 shown in the figure, in this embodiment, the elastic sheet 13 is connected to the first cylinder 9 through a first round hook 14, and the elastic sheet 13 is connected to the second cylinder 11 through a second round hook 15. The elastic sheet 13 pushes the dust-proof plate 4 towards both sides of the retaining ring 6. The elastic sheet 13 is welded to the first round hook 14 and the elastic sheet 13 is welded to the second round hook 15, which can make the elastic sheet 13, the first round hook 14 and the second round hook 15 connected as a whole. The lock body 2 is connected to the connecting member 1 through a card slot, and the retaining ring 6 is connected to the connecting member 1 through a card slot, which can make the retaining ring 6 restrict the moving direction of the dust-proof plate 4. The dust-proof plate 4 is coaxial with the center of the first protrusion 5. The dust-proof plate 4 is slidably connected to the connecting member 1, which can make the dust-proof plate 4 cover the lock hole 3 by sliding. The first concave hole 8 is eccentrically arranged on the dust-proof plate 4, and the first concave hole 8 is coaxial with the center of the first cylinder 9. The second round hook 15 is sleeved on the first cylinder 9. The second concave hole 10, the second cylinder 11 and the cylinder protrusion 12 are coaxial, and the cylinder protrusion 12 prevents the first round hook 14 from falling off.

[0034] The specific implementation process of this embodiment is as follows: The connecting member 1 is fixed on the vehicle, the lock body 2 is installed on the connecting member 1, the first round hook 14 is hooked on the first cylinder 9, the second round hook 15 is hooked on the second cylinder 11, the elastic sheet 13 connects the connecting member 1 and the dust-proof plate 4, the retaining ring 6 restricts the sliding direction of the dust-proof plate 4. Push the dust-proof plate 4 to the right. Due to the elasticity of the elastic sheet 13, the dust-proof plate 4 will quickly slide from the left side of the retaining ring 6 to the lock hole 3 to prevent dust from getting into the lock body 2. The dust-proof plate 4 will not stay in the middle of the inner ring of the retaining ring 6, but will only cover the lock body 2 or move to the left side of the inner ring of the retaining ring 6. The dust-proof plate 4 will not rub against the key, ensuring its service life.

[0035] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model.
