DETAILED DESCRIPTION
[0028] The utility model will be described below in combination with the drawings of the utility model embodiments. Figures 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:
[0030] like Figures 1-12 As shown, this utility model discloses a novel ignition switch, including a housing 1, a lock body 2, a lock cylinder 21, a lock cylinder linkage sleeve 3, a stop seat 4, a top pin seat 5, and an electrical seat 6. The lock body 2 is integrally formed on the upper side of the housing 1, while the lock cylinder 21 is fitted inside the lock body 2. The lower end of the lock cylinder 21 is connected to the lock cylinder linkage sleeve 3, meaning that when the lock cylinder 21 is rotated by the key, the lock cylinder linkage sleeve 3 will rotate as well. The stop seat 4 is fitted under the lock cylinder linkage sleeve 3, and rotates with the lock cylinder linkage sleeve 3. The top pin seat 5 is rotatably mounted under the stop seat 4, and the electrical seat 6 is fixedly fitted under the top pin seat 5. Furthermore, the electrical seat 6 is fixed to the housing 1, so the top pin seat 5 will not rotate with the stop seat 4. Figures 7-10 As shown, the electrical base 6 is provided with several connecting terminals 61, the upper ends of which are integrally formed with contact pieces 62. The electrical base 6 is also provided with several guide pieces 7 for contacting the contact pieces 62 of different connecting terminals 61. These guide pieces 7 are located below the contact pieces 62. The electrical base 6 has springs 71 below the guide pieces 7 for holding the guide pieces 7 upwards. The springs 71 cause the guide pieces 7 to contact the contact pieces 62. A top pin 72 is fixedly connected to the upper end of each guide piece 7. These top pins 72 protrude from the electrical base 6 and slide up and down on the top pin seat 5. The upper ends of these top pins 72 protrude from the top pin seat 5 and abut against the stop seat 4. Figure 11 and 12As shown, a plurality of tumbler grooves 41 are formed on the lower end surface of the gear seat 4, when the upper end of the tumbler 72 is located in the tumbler groove 41, the spring 71 pushes the guide contact piece 7 against the lower end of the contact piece 62, note that the spring 71 in the figure is in a compressed state. During the rotation of the gear seat 4, the gear seat 4 moves relative to the tumbler 72, so some tumblers 72 will enter or exit the tumbler groove 41 of the gear seat 4. When the tumbler 72 enters the tumbler groove 41, the spring 71 pushes the guide contact piece 7 to move upward, so that it is in contact with the lower end of the contact piece 62, thereby making the connection terminal 61 of the contact piece 62 abutting the two ends of the guide contact piece 7 conductive. When the tumbler 72 leaves the tumbler groove 41, the gear seat 4 will press the tumbler 72 to move downward, at this time the guide contact piece 7 will be moved downward by the compressed spring 71, and the contact with the contact piece 62 will be disconnected, thereby cutting off the circuit. Then some guide contact pieces 7 conduct a part of the connection terminal 61, and some guide contact pieces 7 are disconnected, so as to form different combinations, thereby outputting different signal functions.
[0031] Further, as shown in Figure 11 , the gear seat 4 is provided with a slope 42 on both ends of the tumbler groove 41, and as shown in Figure 10 , a ball 73 is rotatably connected to the upper end of the tumbler 72, and the ball 73 is used to abut against the lower end surface of the gear seat 4. The slope 42 is designed to facilitate the rotation of the gear seat 4 relative to the tumbler 72, reduce friction resistance, and improve operation smoothness. The design of the ball 73 further reduces wear and prolongs service life.
[0032] As shown in Figure 2 , the electrical seat 6 is fixedly arranged in the shell 1, and as shown in Figure 4 , a first protrusion 63 is integrally formed on the electrical seat 6, and a first insertion opening 51 is formed on the tumbler seat 5 for inserting the first protrusion 63. This structure makes the tumbler seat 5 and the electrical seat 6 fixed and unable to rotate relative to the shell 1, and the gear seat 4 is rotatably connected to the tumbler seat 5. A second protrusion 31 is integrally formed on the lock cylinder linkage sleeve 3, and a second insertion opening 43 is formed on the gear seat 4 for inserting the second protrusion 31. Therefore, when the lock cylinder linkage sleeve 3 rotates, the gear seat 4 will rotate together.
[0033] As shown in Figure 2 , a center column 8 is arranged on the electrical seat 6, the center column 8 penetrates through the electrical seat 6, the tumbler seat 5 and the gear seat 4 and is fixedly connected with a limiting plate 81, and the gear seat 4 is located between the limiting plate 81 and the tumbler seat 5. The center column 8 provides additional support and stability to prevent relative displacement between components and enhances the stability of the overall structure.
[0034] Further, the specific structure that the lower end of the lock cylinder 21 is connected with the lock cylinder linkage sleeve 3 is that the clamping seat 9 is fixedly connected with the lower end of the lock cylinder 21, the lower end of the clamping seat 9 is inserted into the lock cylinder linkage sleeve 3, the lock cylinder linkage sleeve 3 cannot rotate relative to the clamping seat 9, therefore, when the lock cylinder 21 is rotated by the key, the lock cylinder linkage sleeve 3 is rotated together through the clamping seat 9, in addition, the compression spring 91 is arranged between the clamping seat 9 and the lock cylinder linkage sleeve 3, the compression spring 91 enables the lock cylinder linkage sleeve 3 to be pressed on the gear seat 4, so that the stability of the structure is ensured, and the gear seat 4 is also beneficial to be pressed on the tumbler seat 5 and the tumbler 72.
[0035] In the utility model, the positioning column 32 is radially slidably arranged on the lock cylinder linkage sleeve 3, a plurality of positioning grooves 11 are formed in the inner side wall of the shell 1, the radial spring 33 for pushing the positioning column 32 towards the inner side wall of the shell 1 is arranged on the lock cylinder linkage sleeve 3, the radially slidably arranged positioning column 32 and the positioning groove 11 on the inner side wall of the shell 1 are used in cooperation, so that the accurate positioning of the lock cylinder linkage sleeve 3 when rotating to different gears is ensured, unnecessary shaking and misoperation are avoided, and the reliability of the system is improved.
[0036] The gear seat 4 is made of ultra-high molecular weight polyethylene, and the tumbler 72 and the ball 73 are made of bearing steel material, the gear seat 4 made of ultra-high molecular weight polyethylene material has excellent wear resistance and self-lubricating performance, the tumbler 72 and the ball 73 made of bearing steel material have high strength and wear resistance, and the durability and reliability of the whole device are significantly improved.
[0037] The working principle of the utility model is as follows: when the key is inserted into the lock cylinder 21 and rotated, the lock cylinder 21 drives the lock cylinder linkage sleeve 3 to rotate through the clamping seat 9, the rotation of the lock cylinder linkage sleeve 3 further drives the gear seat 4 to rotate, a plurality of tumbler grooves 41 are formed in the gear seat 4, and the tumbler 72 moves in the tumbler groove 41 in the rotation process of the gear seat 4. When the tumbler 72 enters the tumbler groove 41, the spring 71 pushes the guide piece 7 to move upwards, so that the guide piece 7 is in contact with the lower end of the contact piece 62, so that the connecting terminal 61 of the contact piece 62 abutting the two ends of the guide piece 7 is in conduction. When the tumbler 72 leaves the tumbler groove 41, the gear seat 4 drives the tumbler 72 to move downwards, at this time, the guide piece 7 is moved downwards by the compressed spring 71, and the contact with the contact piece 62 is disconnected, so that the circuit is cut off. Different gears (such as LOCK, ACC, ON and START) correspond to different positions of the tumbler 72, each position has a specific combination mode of the tumbler 72 entering or leaving the tumbler groove 41, and different conduction path combinations are formed, and different electric signal functions are output. Therefore, when the key rotates the lock cylinder 21 to different angles, different control functions are realized. (Among them, the corresponding circuit of each gear and different terminals is prior art, which will not be described in detail here).
[0038] Meanwhile, it needs to be pointed out that the terms indicated by the utility model, such as "front", "rear", "vertical", "horizontal" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element indicated must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the protection scope of the utility model.
[0039] The above only describes the preferred embodiments of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement, improvement and the like made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
