AI Technical Summary
The existing ignition lock has an unstable connection between the lock cylinder and the rotor, poor sealing and waterproofing performance, and cannot control the car's P gear, posing an operational risk.
A sealed and waterproof ignition power lock was designed. By setting a rotating shaft sealing ring between the lock cylinder and the rotor, and setting a cable connection between the lock tongue and the car's P gear control lever, the sealing performance and stability are enhanced. At the same time, a lock cylinder compression spring washer assembly is added between the lock cylinder and the base to improve rotational flexibility and stability.
It achieves stable and smooth rotation of the lock cylinder and rotor, improves sealing performance, ensures normal operation of the car's circuit, and can control the car's P gear lock, thus improving work efficiency.

TECHNICAL FIELD
[0001] The present application relates to a switch assembly, in particular to a sealed waterproof ignition power lock. BACKGROUND
[0002] Ignition lock, also known as ignition switch, is a multi-gear switch, which needs to be operated by the corresponding key. The ignition lock is usually used to control ignition circuit, instrument circuit, electronic control system, starting circuit, etc., and has multiple gears and corresponding functions such as starting ignition, extinguishing, unlocking, etc. However, the connection between the lock core of the lock head assembly and the rotor of the switch assembly is in the form of buckling, which is not very smooth, stable and reliable to rotate the rotor by the lock core. The overall sealing and waterproof performance is not ideal, which has a negative impact on the operation of the automobile ignition and its related circuits. When the automobile stops running, it needs to be put into P gear (parking gear), which is controlled by an electronic hand brake button, which is sometimes integrated on the gear lever. The operation control of the automobile P gear is not completed by the ignition lock. SUMMARY
[0003] The purpose of the present application is to overcome the above-mentioned deficiencies, and to provide a sealed waterproof ignition power lock with stable and smooth connection transmission, good sealing performance, and the ability to control the locking of the automobile P gear.
[0004] The purpose of the present application is achieved by the following technical scheme: the sealed waterproof ignition power lock is composed of a lock head assembly, a base assembly and a switch assembly. The lock head assembly includes an ignition lock head, a lock core and a plug spring assembly. The base assembly includes a base, a cover and a lock tongue. The switch assembly includes a rotor, a movable contact spring assembly, a steel ball spring assembly, a cover plate and a plug-in assembly. The inner end of the lock core of the lock head assembly is connected to the rotor of the switch assembly through a rotating shaft, and a rotating shaft sealing ring is installed between the rotating shaft and the lock core. The lock tongue is connected to the lock core through a lock tongue bracket, and the lock tongue is connected to the automobile P gear control rod through a cable.
[0005] A cover plate sealing ring is installed on the inner wall of the cover plate and between the cover plate and the base, which further enhances the sealing and waterproof performance. A lock core compression spring washer assembly is installed between the lock core and the base and near the rotating shaft position, which improves the flexibility and stability of the lock core rotation. A nut is installed in the front part of the base, which is connected to the outer surface of the lock core through a positioning pin, to facilitate quick and secure installation.
[0006] With this invention, rotating the lock cylinder to the ignition angle position drives the rotor to rotate via the shaft. The rotation is stable, reliable, and smooth, allowing the starter switch assembly to ignite the car smoothly. The shaft sealing ring provides better sealing performance and good waterproofing, effectively ensuring the normal operation of the car's related circuits and extending their service life. Rotating the lock cylinder to the P-position locking angle position causes the latch to extend the cable, locking the car in the P-position (parking gear) control lever. This achieves a multi-functional application of the ignition lock and improves work efficiency. Attached Figure Description
[0007] Figure 1 This is a schematic diagram of the structure of the sealed and waterproof ignition power lock of the present invention. Detailed Implementation
[0008] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0009] like Figure 1 As shown, the present invention relates to a sealed and waterproof ignition power lock, comprising a lock head assembly, a base assembly, and a switch assembly. The lock head assembly includes an ignition lock head 1 (composed of a lock cylinder cover and a flip-plate torsion spring assembly), a lock cylinder 6, and a insert spring assembly 7 (all of which are known technologies). The base assembly includes a base 10, a cover 9, and a latch 28 (all of which are known technologies). The switch assembly includes a rotor 13, a moving contact spring assembly 15, a steel ball spring assembly 16, a cover plate 18, and a plug assembly 25 (composed of connectors, wires, wire clamps, etc., all of which are known technologies). The inner end of the lock cylinder 6 of the lock head assembly is connected to the rotor 13 of the switch assembly via a rotating shaft 11, and a rotating shaft sealing ring 12 is installed between the rotating shaft 11 and the lock cylinder 6. The latch 28 is connected to the lock cylinder 6 via a latch bracket 29, and the latch 28 is connected to the vehicle's P gear control lever via a pull cable 32.
[0010] A cover sealing ring 20 is installed on the inner wall of the cover plate 18, between the cover plate 18 and the base 10, to further enhance its sealing and waterproof performance. A nut 30 is installed inside the front part of the base 10. This nut 30 is connected to the outer surface of the lock cylinder 6 (which has a positioning pin groove) via a positioning pin 31 for convenient, quick, and secure installation. A lock cylinder compression spring washer assembly 27 (a combination of a lock cylinder compression spring and a lock cylinder washer) is installed between the lock cylinder 6 and the base 10, near the pivot 11, to improve the flexibility and stability of the lock cylinder rotation.
[0011] The working principle of the present application is that the automobile key is inserted into the key hole on the lock core cover of the ignition lock head 1 of the lock head assembly, and the automobile key is rotated by 45 degrees to the ignition position to rotate the lock core 6 through the rotating shaft 11 to drive the rotor 13 to rotate, the starting switch assembly is started to successfully ignite the automobile, at this time the automobile key is in "unpluggable" state; when the brake pedal is stepped on to stop driving, the automobile key is reversely rotated by 45 degrees to rotate the lock core to the off position to realize off, and then the lock core is rotated by 90 degrees to the P position to lock the position, and the lock tongue 6 drives the pull rope 32 to extend outward to realize the automobile P position locking of the automobile P position control rod.
