Parallel double Hall sensor ignition switch

Abstract

The utility model provides a parallel ignition switch with double Hall sensors. The rotating ring groove is provided with at least two Hall sensors close to the periphery of the rotating ring, and each Hall sensor is independently connected with one igniter through electric signals, so that when the crankshaft of the engine drives the rotating ring to rotate, the rotating ring drives the magnet to pass through all the Hall sensors, and the rotating ring rotates. Therefore, when one Hall sensor cannot detect the change of the magnetic field and cannot activate the igniter to ignite the combustion chamber, the other Hall sensor can detect the change of the magnetic field and activate the other igniter to ignite the combustion chamber; compared with an overlapped ignition switch with double Hall sensing elements, when the magnetism of the magnet becomes weak due to the fact that the ignition switch is used for a too long time or temperature influence, the situation that one Hall sensor is separated by the other Hall sensor, is far away from the magnet and cannot be activated by the magnet is avoided; the utility model belongs to the technical field of ignition switches.

[0007] 1. The rotation ring is provided with at least two Hall sensors close to the outer periphery of the rotation ring, and each Hall sensor is independently connected with an igniter by an electric signal.

[0008] 2. Each Hall sensor is vertically arranged beside the outer periphery of the rotation ring, and compared with the overlapping double Hall sensor ignition switch, when the magnetism of the magnet is weakened due to long use time or temperature influence, the Hall sensor cannot be activated by the magnet because it is separated from the magnet by another Hall sensor, thereby further improving the stability of the engine.

[0009] 3. All the Hall sensors are vertically arranged beside the outer periphery of the rotation ring, so that the corresponding igniters can be ignited by the Hall sensors at the same time, and when one igniter cannot normally ignite, another igniter can also timely compensate.

[0010] In order to further optimize the above technical solutions, one or more of the following embodiments can be combined without conflict.

[0011] In some embodiments, the distance between each Hall sensor and the outer periphery of the rotation ring is the same.

[0012] According to the technical solution, since the distance between each Hall sensor and the outer periphery of the rotation ring is the same, when the magnet passes through all the Hall sensors, the mechanism of the magnet activating the Hall sensors is the same, thereby further improving the stability.

[0013] In some embodiments, two adjacent Hall sensors form a group, the outer periphery of the rotation ring is provided with at least two groups of Hall sensors in an equidistant array, each group of Hall sensors is centrally symmetrically arranged, the outer periphery of the rotation ring is fixedly provided with the same number of magnets as the number of Hall sensor groups, and the distance between adjacent two magnets is the same as the distance between adjacent two groups of Hall sensors.

[0015] In some embodiments, the magnet is provided with an outer wall surface extending to and having the same arc as the outer circumferential surface of the rotating ring.

[0016] According to the technical solution, the magnet can give the Hall sensor a stable magnetic field during the passing of the magnet through the Hall sensor, and foreign matter can be effectively prevented from being stuck in the gap at the position of the magnet to interfere with the magnetic field of the magnet during rotation of the rotating ring.

[0017] In some embodiments, the magnet is provided with an inner wall surface located at a symmetrical position of the outer wall surface, the inner wall surface having the same arc as the outer wall surface and the same center.

[0018] According to the technical solution, the magnet can give the Hall sensor a stable and consistent magnetic force during the passing of the magnet through the Hall sensor, thereby further improving stability. BRIEF DESCRIPTION OF DRAWINGS

Each Hall sensor 3 is arranged in parallel and vertically beside the outer periphery of the rotating ring 6, and the distance between each Hall sensor 3 and the outer periphery of the rotating ring 6 is the same.

[0031] The following is the working principle of the parallel double-Hall-sensor ignition switch.

[0032] When the rotating ring 6 is rotated by the crankshaft of the engine, the rotating ring 6 drives the magnet 4 to pass through all the Hall sensors 3. At this time, each Hall sensor 3 gives a signal to the corresponding igniter 7, and the corresponding igniter 7 controls the torch 9 to ignite in the combustion chamber. At the same time, since all the Hall sensors 3 are arranged in parallel and vertically beside the outer periphery of the rotating ring 6, when the rotating ring 6 drives the magnet 4 to pass through the parallel Hall sensors 3, the Hall sensors 3 give signals to the corresponding igniters 7 at the same time. At this time, the igniters 7 control the corresponding torches 9 to ignite in the combustion chamber at the same time.

[0033] In addition, when one of the Hall sensors 3 cannot detect the change of the magnetic field and cannot activate the igniter 7 to ignite in the combustion chamber, the other Hall sensor 3 can detect the change of the magnetic field and activate the igniter 7 connected with the torch 9 to ignite in the combustion chamber.
