Abstract

The invention discloses a security ignition switch assembly. The security ignition switch assembly comprises a lock head assembly (1), a base assembly (2) and a switch assembly (5); the lock head assembly comprises a key (11), an ignition lock head (12), an ignition lock cylinder (14), an ignition lock plate spring assembly (16) and a self-lock lever (18); a double-head pin (23) and a double head pin pressure spring (24) are mounted in one side of the ignition lock head; a limiting plate (26) and a limiting plate spring (27) are mounted in the other side of the ignition lock head; and a boss (37) is arranged on the base (31) of the base assembly at a location contacting with the limiting plate. According to the ignition switch assembly provided by the invention, the limiting plate must be made to touch the boss on the base, so that the limiting plate is pressed down along the limiting plate spring; the rotation switching among the switch gears can be finished by touching the boss through pressing down the limiting plate spring; therefore, the switching security among the switch gears is improved; the normal driving work and the vehicle performance quality of the vehicle are effectively ensured; and the security ignition switch assembly is especially applicable to a truck and a goods van.

Description

Safety type ignition switch assembly

Technical field

The present invention relates to a kind of switch assembly, be specifically related to a kind of automobile ignition switch assembly。

Background technology

At present; for motor vehicle ignition switch assembly has multiple gears such as startup, igniting, closedown; general do not have safety precautions from igniting between closedown gear; when vehicle traveling is subject to relatively pitchpole on comparatively uneven road surface; it sometimes appear that jump to closedown shelves from a fire screen suddenly and cause vehicle moment to stop working; there is bigger potential safety hazard, vehicle performance be will also result in infringement。

Summary of the invention

It is an object of the invention to overcome above-mentioned deficiency, and safety type ignition switch assembly during conversion between a kind of gear with protective measure is provided。

The purpose of the present invention realizes by following technical solution: safety type ignition switch assembly, including tapered end assembly, pedestal assembly, switch assembly, this tapered end assembly is connected with switch assembly by connecting axle, this tapered end assembly includes key, igniting tapered end, igniting lock core, ignition lock leaf spring assemblies, self-locking lever, in the side of described igniting tapered end built with double end pin and double end pin stage clip, at the opposite side of described igniting tapered end built with banking stop and spacing leaf spring, on the pedestal of described pedestal assembly, and with the banking stop touching position of described tapered end assembly, there is boss。

After adopting the present invention, the corresponding rotation of igniting lock core and ignition lock leaf spring assemblies is driven by the rotating operation of key, when required gear is changed, the boss on banking stop touching pedestal must be made to promote banking stop to be pressed downward against along spacing leaf spring, the conversion that just can complete between switch position to touch this boss to operate。Thus must flow through manual operation and pressing down spinning movement could realize the conversion that switch position is particularly lighted a fire and closed gear, can not automatic tripping gear shift, improve the safety of conversion between switch position, the normal travel operation of effective guarantee vehicle and vehicle performance quality, be particularly well-suited to truck, lorry。

Detailed description of the invention

Below in conjunction with drawings and the embodiments, the present invention is described in further detail。

As shown in Figures 1 to 4, safety type ignition switch assembly of the present invention, including tapered end assembly 1, pedestal assembly 2, switch assembly 5, this tapered end assembly 1 is connected with switch assembly 5 by connecting axle 4 (and connecting axle spring 3), this tapered end assembly 1 includes key 11, igniting tapered end 12, igniting lock core 14 (and lock core mask 13), ignition lock leaf spring assemblies 16 (including locking plate and spring), self-locking lever 18, in the side of described igniting tapered end 12 built with (linking together) double end pin 23 and double end pin stage clip 24, at the opposite side of described igniting tapered end 12 built with (linking together) banking stop 26 and spacing leaf spring 27, on the pedestal 31 of described pedestal assembly 2, and with banking stop 26 touching position of described tapered end assembly 1, there is boss 37 (described boss 37 is integrated with pedestal 31)。

Wherein, described banking stop 26 is embedded in the opposite side of igniting tapered end 12 by spacing film trap 28 and is supported by spacing leaf spring 27, this spacing leaf spring 27 withstands on igniting tapered end 12 (to have the motion work for banking stop of certain spatial separation), and described pedestal assembly 2 includes pedestal 31, dead bolt capping 33, latch bolt spring 34, dead bolt slide block 35, dead bolt 36。

The present invention drives the corresponding rotation of igniting lock core and ignition lock leaf spring assemblies by the rotating operation of key。When required gear is changed, must make banking stop touching pedestal on boss and promote banking stop to be pressed downward against along spacing leaf spring, to descending, the spacing making banking stop in spacing film trap and to light a fire between tapered end diminishes, to touch the rotation conversion that the operation of this boss just can complete between switch position。Therefore, it is necessary to manually operate and press down spinning movement could realize the conversion that switch position is particularly lighted a fire and closed gear, thus improve the safety of conversion between switch position。

Claims
