Description

Technical Field

[0001] The present invention relates to the technical field of starter motors, in particular to a starter motor for an automobile. Background Art

[0002] The automotive starter motor is the core actuator of the engine starting system. It converts battery electrical energy into mechanical energy, driving the engine flywheel to rotate and providing initial power to the engine to overcome static inertia. The starter motor typically consists of an electric motor coupled with an electromagnetic control structure to insert the gear mounted on the motor into the meshing teeth on the outer side of the flywheel for control. Current automotive starter motors are not easy to automatically control and stabilize the flywheel. When the engine needs to be restarted immediately after stopping or repeatedly started, the flywheel is still rotating back and forth. Directly connecting the gears can easily cause tooth snapping and increase the load on the starter motor. Furthermore, the freely moving flywheel is easily rotated by friction during gear meshing, further reducing the meshing speed. Typically, the motor is powered to start the engine when the gears move to engage the flywheel. However, if the gears are not meshed or fully inserted into the flywheel, direct control and drive can easily cause uneven force on the gears, leading to tooth breakage and other problems. It also makes it difficult to monitor the gear clearance in real time. Excessive clearance can easily cause slippage, affecting transmission quality and making it difficult to prompt personnel to replace the gears in a timely manner.

[0003] To this end, we propose a starter motor for an automobile. Summary of the Invention

[0017] The use of a gap detection component can automatically squeeze and fit onto the side of the driving gear when the driving gear is reset. Once the gap between the driving gear and the one-way clutch is too large, the driving gear is prone to shaking. The poor positioning accuracy of the driving gear can be detected in time, and prompts can be given in time to reduce the risk of jamming with the flywheel due to excessive clearance of the driving gear.

At the same time, this structure can automatically control the docking of the flywheel teeth to avoid jamming. At the same time, this structure can use the one-way clutch 305 to ensure that the driving gear 306 is smoothly reset after starting the engine. This structure is simpler and can use the electromagnetic propulsion member 2 for direct electromagnetic propulsion engagement.

[0023] The in-place detection member 4 includes: an in-place detection ring 401, an extrusion ring 402, an extrusion spring 403 and an electric ring 404.

The control of this structure is simple and reasonable, avoiding the problem that the existing driving gear 306 is not accurate enough by mainly detecting the displacement position of the propulsion shaft 203. As the force spring 303 pushes the driving gear 306 into the flywheel, until the driving gear 306 is completely inserted into the flywheel, the keyway sleeve 304 will squeeze the detection ring 401 into place, compressing the extrusion spring 403, so that the extrusion ring 402 and the power connection ring 404 are in contact and connected to electricity. At this time, the power motor 101 will be energized to drive the one-way clutch 305 to drive the driving gear 306 to rotate, drive the anti-flywheel rotation to start the engine, and the one-way clutch 305 can be used when the flywheel speed is high. At this time, the inner ring of the one-way clutch 305 is stopped, and the outer ring will not lock and is in idling, which is no different from the one-way clutch structure of the existing starting motor.

Once the gap between the driving gear 306 and the one-way clutch 305 is too large, the driving gear 306 is prone to shaking. The poor positioning accuracy of the driving gear 306 can be detected in time, and prompts can be given in time, which can improve the actual use safety and facilitate timely replacement work. At the same time, it reduces the risk of the driving gear 306 being stuck with the flywheel due to excessive clearance. The structure is simpler and more reasonable, and the detection through the gap detection part 5 is intuitive.

[0025] 1 and 2. The second embodiment, on the basis of the first embodiment, the feed control member 6 includes: a detection slot block 601, a stabilizing switch 602 and a pressing block 603, the two sides of the detection slot block 601 are fixedly mounted on the connecting cylinder 102 by a row of bolts; a stabilizing switch 602 is fixedly mounted on the inner side of the detection slot block 601; a pressing block 603 is slidably mounted on the detection slot block 601; the feed control member 6 also includes: a crushing block 604, a crushing block 604 is slidably plugged into the pressing block 603, and a spring is provided at the bottom of the crushing block 604, and the spring end at the bottom of the crushing block 604 is connected to the inner side of the pressing block 603; the crushing block 604 is located on the side of the extrusion block 204; the two sides of the crushing block 604 are inclined structures; the flywheel stabilizer 7 includes: a stabilizing slider 701, a phase The repelling electromagnet 702, the propulsion magnet 703 and the retraction spring 704, and the end of the stabilizing slider 701 are provided with a rubber pad; the stabilizing slider 701 is slidably inserted into the telescopic groove 1021; the repelling electromagnet 702 is fixedly installed on the inner side of the connecting tube 102; the propulsion magnet 703 is fixedly installed on the stabilizing slider 701, and the repelling electromagnet 702 is aligned with the propulsion magnet 703; the retraction spring 704 is fixedly installed on the bottom of the stabilizing slider 701, and the other end of the retraction spring 704 is connected to the side of the connecting tube 102; the stabilizing switch 602 is electrically connected to the repelling electromagnet 702, and the flywheel stabilizing member 7 is used in conjunction with the feed control member 6 to realize automatic control of the flywheel brake stabilization during the startup work, which is convenient for the insertion of the driving gear 306 to avoid driving When the gear 306 rotates and is inserted, the friction shakes the flywheel, which improves the stability of the flywheel. It can improve the stability of the flywheel when the drive gear 306 is inserted into the flywheel for docking. At the same time, the flywheel stabilizer 7 can be automatically controlled when the drive cylinder 301 pushes the docking drive gear 306. At the same time, the flywheel stabilizer 7 will only assist in braking before the drive flywheel rotates to start the engine. It will not cause friction interference after the engine is started. It can be more suitable for the working condition of the flywheel swinging back and forth during continuous starting, avoiding the problem of excessive load on the power motor 101 when the inertia force when the flywheel swings back and forth is directly docked with the drive gear 306 for starting, thereby improving the service life of the power motor 101, and can also increase the speed at which the drive gear 306 is inserted into the flywheel, avoiding the problem of teeth hitting when the flywheel rotates back and forth. The problem is that the structure is simple and reasonable, and the control is automatic. When the propulsion arm 2031 drives the driving cylinder 301 to move, it can drive the extrusion block 204 to move and extrude the crush block 604. Because the spring force under the crush block 604 is relatively large, the pressing block 603 can be driven to slide and extrude the stable switch 602. At this time, the repulsive electromagnet 702 is energized and the propulsion magnet 703 repels, driving the end of the stable slider 701 to extend out of the friction flywheel disk. At this time, as the propulsion arm 2031 continues to move, the extrusion block 204 can be driven to move and slide over the crush block 604. The spring under the crush block 604 is compressed. At this time, the stable switch 602 is no longer squeezed by the pressing block 603, and the subsequent keyway sleeve 304 will also be squeezed into place. The detection ring 401 controls the power-on start-up work.

[0026] The working principle of this embodiment is as follows: bolts are passed through the two through holes on the connecting cylinder 102 to install it on one side of the engine. When the engine needs to be started, the cylindrical electromagnet 202 is energized, and the magnetic propulsion shaft 203 drives the propulsion arm 2031 to drive the cylinder 301 to move. By utilizing a circle of spiral protrusions in the driving cylinder 301, when the driving cylinder 301 moves, the torsion sleeve 1012 will be guided to rotate. At the same time, as the driving cylinder 301 moves, the driving cylinder 301 can squeeze the force spring 303. At this time, even if the driving gear 306 fails to be inserted into the flywheel meshing, the torsion sleeve 1012 drives the starting shaft 1011 to rotate together. At this time, the starting shaft 1011 can drive the keyway sleeve 304 to rotate. The one-way clutch 305 and the driving gear 306 are driven to rotate. At this time, the force spring 303 is squeezed forward by the driving cylinder 301 to ensure that the driving gear 306 can be inserted into the flywheel meshing for plugging. As the engine starts, the power supply of the cylindrical electromagnet 202 can be disconnected. Under the pull of the tension spring 205 at the tail of the propulsion shaft 203, the propulsion shaft 203 can drive the driving cylinder 301 to retract, and the force spring 303 is pulled by the rotating ring 302. The force spring 303 is limited in length, and the keyway sleeve 304 can be pulled to drive the driving gear 306 to be pulled out of the flywheel to achieve separation. During the process, the setting of the one-way clutch 305 can prevent the power motor 101 from being driven by the high speed of the flywheel The basic principle of the one-way clutch 305 is that when the speed of the inner ring is higher than that of the outer ring, it is locked, and when the speed of the outer ring is higher than that of the inner ring, it is in an idling state. The one-way clutch 305 can be in a high speed flywheel. At this time, the inner ring of the one-way clutch 305 is stopped, and the outer ring will not be locked and is in idling. When the propulsion arm 2031 drives the drive cylinder 301 to move, it can drive the extrusion block 204 to move and squeeze the crush block 604. Because the spring force under the crush block 604 is large, the pressing block 603 can be driven to slide and squeeze the stabilizing switch 602. At this time, the repelling electromagnet 702 is energized and repels the propulsion magnet 703, driving the end of the stabilizing slider 701 to extend out of the friction flywheel disc. At this time, as the propulsion arm 203 drives the driving cylinder 301 to move, it can drive the extrusion block 204 to move and squeeze the crushing block 604. 1 continues to move, which can drive the extrusion block 204 to move and slide over the crushing block 604. The spring under the crushing block 604 is compressed. At this time, the stabilizing switch 602 is no longer squeezed by the pressing block 603. The keyway sleeve 304 is also squeezed into place. The detection ring 401 controls the power supply to start the work. The end of the stabilizing slider 701 no longer squeezes the flywheel after the repulsive electromagnet 702 is powered off to prevent excessive wear. Subsequently, as the propulsion arm 2031 retracts and resets, it drives the extrusion block 204 to reset together. During the process, the crushing block 604 is strongly compressed again. Because the stabilizing switch 602 is in front of the pressing block 603, all the stabilizing switches 602 will not be squeezed, so that the flywheel will be braked only when the engine is started.When the drive gear 306 is reset, if the clearance of the drive gear 306 is too large, the drive gear 306 will easily shake. Under the pressure of the extrusion head 503 and the tail spring, the drive gear 306 will deviate and no longer be coaxial with the starting shaft 1011. If the deviation is too large, the extrusion head 503 will move in alignment with it, and the protrusion at the end of the connection post 504 will move to align with the gap spring 502, thus completing the circuit and the buzzer 103 will sound an alarm.
