Description

Technical Field

[0001] This utility model relates to the field of automotive ignition system technology, and in particular to an ignition lock cylinder assembly. Background Technology

[0002] Ignition lock cylinder assemblies are typically installed inside the ignition lock bracket on the side of the vehicle's steering column. Traditional ignition lock cylinder assemblies usually include components such as a lock cylinder, lock cylinder, lock block, and safety lever. In terms of installation, most existing ignition lock cylinder assemblies are fixed to the ignition lock bracket with screws, which is somewhat aesthetically unappealing. Some ignition lock cylinder assemblies use lock blocks to lock into corresponding slots within the ignition lock bracket, thus preventing the ignition lock cylinder assembly from coming out. However, this is somewhat troublesome to disassemble, requiring the removal of many components of the ignition lock cylinder assembly itself before the entire ignition lock cylinder assembly can be removed. Therefore, this application makes improvements to address the above-mentioned technical problems. Utility Model Content

[0028] The following will refer to the appendix in the embodiments of this utility model. Figure 1-12 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Example 1:

[0030] like Figures 1 to 10As shown, this utility model discloses an ignition lock cylinder assembly, including a lock head 1, a lock cylinder 2, a lock block 3, a lock block compression spring 32, a safety lever 4, a lock head cover 5, a lock cylinder cover 7, a retaining ring 8, and a pin 9. The lock cylinder 2 is fitted inside the lock head 1. The lock cylinder cover 7 covers the upper side of the lock cylinder 2, and the lock head cover 5 is detachably connected to the upper side of the lock head 1. The inner ring of the lock head cover 5 extends to cover the lock cylinder cover 7. A lock block groove 11 is provided on one side of the lock head 1, and the lock block 3 is disposed within the lock block groove 11. The pin 9 is fixedly connected to the lock block groove 11 of the lock head 1, and one end of the lock block 3 is rotatably fitted onto the pin 9. The groove 11 is provided with a lock block compression spring 32 for pushing the end of the lock block 3 away from the pin 9 outward into the lock block groove 11. In addition, the lock block 3 has an inclined drive port 31 on the end away from the pin 9, which gradually slopes outward from the lock block groove 11 from top to bottom. The upper side of the lock head 1 has a through-hole 12 that leads to the lock block groove 11 and corresponds to the upper side of the inclined through-hole 71. The lock cylinder cover 7 has a through-hole 71 corresponding to the through-hole 12. A limiting block 33 is provided on the lower side of the lock block, and the lock head 1 has a limiting groove 14 for the limiting block 33 to move and cooperate. This structure is used to limit the angle at which the lock block is pushed out by the lock block compression spring 32.

[0031] The specific structure of the lock cylinder cover 5 detachably connected to the upper side of the lock cylinder 1 is as follows: a first latch 51 is provided on the inner side wall of the lock cylinder cover 5, and a second latch 13 corresponding to the first latch 51 is provided on the outer side wall of the lock cylinder 1. A retaining ring 8 is provided between the first latch 51 and the second latch 13. The lock cylinder cover 5 is secured to the lock cylinder 1 by the retaining ring 8, which is stable and reliable. In addition, the lower side of the lock cylinder cover 7 is integrally formed with a limiting outer edge 72, and the upper side of the lock cylinder cover 5 extends and abuts against the upper side of the limiting outer edge 72. The design of the limiting outer edge 72 prevents the lock cylinder cover 7 from shifting during use, further ensuring the safety and reliability of the ignition lock cylinder 2 assembly.

[0032] Furthermore, in this utility model, the lock cover 5 is provided with an operation port 52 corresponding to the through port 71.

[0033] When installing this utility model into the ignition lock bracket, first press the lock block 3 into the lock block groove 11 by hand, and then install the ignition lock cylinder 2 assembly into the ignition lock bracket. After installation, the lock block 3 will automatically snap into the corresponding slot in the ignition lock bracket under the action of the lock block compression spring 32, thereby fixing the ignition lock cylinder 2 assembly.

[0034] When it is necessary to disassemble the ignition lock cylinder 2 assembly, the user can insert a long-handled tool (such as a screwdriver or other slender tool) through the through-hole 71 on the lock cylinder cover 7, through the insertion hole 12 on the lock head 1, and finally into the tilting drive hole 31 on the lock block 3. Continue pushing the tool to make the lock block 3 retract into the lock block groove 11 against the pressure of the lock block spring 32, thereby releasing the lock block 3 from the ignition lock bracket slot. After the lock block 3 is fully retracted, the user can directly pull the ignition lock cylinder 2 assembly upwards. The entire disassembly process is quick and easy, without the need to disassemble other parts.

[0035] In order to protect the operating port 52 from dust and other contaminants and improve the cleanliness of the appearance, a covering component is provided on the lock cover 5 to cover the operating port 52.

[0036] Specific examples Figure 8-10 As shown, in this embodiment, the covering assembly includes a cover plate 61 located on the upper side of the lock head cover 5. Additionally, the lock head cover 5 has an installation opening 53 on the upper side of the operating port 52, and an arc-shaped groove 54 on one side of the installation opening 53. A connecting block 62 is fixedly connected to the lower side of the cover plate 61 away from the arc-shaped groove 54. An arc-shaped sliding rod 63 is fixedly connected to the connecting block 62, and the arc-shaped sliding rod 63 slides within the arc-shaped groove 54. Furthermore, a magnetic block 64 is provided on the side of the installation opening 53 away from the arc-shaped groove 54. The connecting block 62 is made of metal for attracting the magnetic block 64. The combined design of the cover plate 61, the arc-shaped sliding rod 63, and the magnetic block 64 provides a convenient and stable covering method. Users can easily open or close the operating port 52 by gently sliding the cover plate 61, which is convenient and does not affect the overall aesthetics. The magnetic block 64 and the metal connecting block 62 ensure that the cover 61 is securely closed and prevents accidental opening.

[0037] Example 2:

[0038] like Figure 10 and Figure 11 As shown, this embodiment is basically the same as embodiment 1, except that the covering component in this embodiment is a rubber plug 65. The rubber plug 65 is interference-fitted onto the operating port 52, and the lock cover 5 has an easy-removal slot 55 on one side of the rubber plug 65, making it easy for the user to remove the rubber plug 65. The rubber plug 65 in this embodiment is interference-fitted onto the operating port 52, forming a simple and effective sealing method. It not only prevents foreign objects from entering, but is also easy to remove.
