Description

Technical Field

[0001] This utility model relates to the field of motor sealing technology, and in particular to a starter electromagnetic switch assembly. Background Technology

[0002] The electromagnetic switch is a control switch on the starter motor. When the coil of the electromagnetic switch is energized, the moving iron core moves under the action of the magnetic field, thereby pushing the shift fork to engage the drive gear at the end of the starter motor with the flywheel of the engine. Furthermore, under the action of the magnetic field, the moving iron core moves toward and pushes a trigger switch, causing the trigger plate of the trigger switch to connect the power supply. The motor is then energized and runs, causing the engine to start under the drive of the motor's drive gear, ultimately achieving the purpose of starting the engine.

[0003] However, with the continuous development and progress of society, the application environment of starters has become more diverse. When starting the starter in environments with heavy rain, wading, or high dust levels, the starter's electromagnetic switch often fails to function due to the intrusion of water or dust, leading to the starter's malfunction. Although a switch cover at one end of the electromagnetic switch body can prevent water or dust from entering, the gap between the switch cover and the electromagnetic switch body will increase due to engine vibration, reducing the effectiveness of preventing water or dust. At this point, water or dust will intrude into the sealed cavity and then enter the moving iron core cavity through the gap between the inner shell and the moving iron core, preventing the moving iron core from moving normally. Water or dust may even enter the trigger cavity through the limiting through-hole, causing the trigger plate of the trigger structure to fail to properly connect the motor's power supply. Utility Model Content

[0004] One advantage of this invention is that it provides a starter electromagnetic switch assembly, wherein the waveform seal prevents water or dust from entering the sealed cavity from the connection between the main body housing and the switch cover and from entering the moving core cavity through the opening, thereby preventing water or dust from entering between the moving core and the main body inner shell, which would prevent the moving core from sliding smoothly in the moving core cavity, thus enabling the starter electromagnetic switch assembly to operate smoothly in environments with heavy rain, water wading, and high dust levels.

[0005] Another advantage of this utility model is that it provides a starter electromagnetic switch assembly, wherein the waveform seal includes at least one fixed ring, at least one connecting ring, and at least one sealing sleeve. The fixed ring is connected to the connecting ring through the sealing sleeve. The moving iron core is divided into a moving part, a sealing element fixing part, and a connecting part. The moving part is slidably disposed in the moving cavity of the iron core. The shift fork is rotatably connected to the connecting part. The sealing element fixing part is located between the moving part and the connecting part, and the sealing element fixing part has a sealing element fixing plate. At least one connecting ring is coaxially mounted on the sealing element fixing plate, and the fixed ring is fixed to the inner shell of the main body through the mounting ring and located outside the opening, thereby sealing the opening. This prevents water or dust in the sealing cavity from entering the opening of the inner shell of the main body through the connection between the fixed ring and the mounting ring or the connection between the connecting ring and the sealing element fixing plate. This allows the starter electromagnetic switch assembly to operate smoothly in environments with water and high dust levels, making the starter electromagnetic switch assembly suitable for more application scenarios and achieving a longer service life.

[0006] Another advantage of this utility model is that it provides a starter electromagnetic switch assembly, wherein the diameter of the fixed ring of the waveform seal is larger than the diameter of the connecting ring of the waveform seal. Since the fixed ring is connected to the connecting ring through the sealing sleeve, the sealing sleeve as a whole forms a conical inclined surface, so that water or dust will fall from the conical inclined surface of the sealing sleeve. Furthermore, when the moving iron core is moved in the moving cavity of the iron core under the action of the magnetic field, the connecting ring will move towards or away from the fixed ring under the pull of the sealing fixing plate of the sealing fixing part. During the movement of the connecting ring relative to the fixed ring, in order to stabilize the connecting ring... The sealing sleeve is disposed on the sealing plate. The sealing sleeve needs to be folded to one side at a predetermined angle. However, when water or dust falls and settles on the surface of the sealing sleeve, the sealing sleeve cannot be folded due to the obstruction of the water or dust. Therefore, since the sealing sleeve is disposed between the fixing ring and the connecting ring to form a conical inclined surface, the sealing sleeve can be smoothly folded to one side at a predetermined angle during the movement of the connecting ring relative to the fixing ring. As a result, the connecting ring is stably disposed on the sealing plate, thereby ensuring that water or dust will not enter the opening from the connection between the connecting ring and the sealing plate, and ultimately allowing the starter solenoid switch assembly to maintain normal operation.

[0007] Another advantage of this utility model is that it provides a starter electromagnetic switch assembly in which multiple reinforcing rings are uniformly arranged between the fixed ring and the connecting ring with varying inner diameters. The minimum inner diameter of the reinforcing ring is larger than the inner diameter of the connecting ring, and the maximum inner diameter of the reinforcing ring is smaller than the inner diameter of the fixed ring. The fixed ring, the connecting ring, and the reinforcing ring are connected by a sealing sleeve. During the movement of the connecting ring relative to the fixed ring, the sealing sleeve is restricted by the reinforcing ring to be folded at predetermined positions and times, avoiding damage to the sealing sleeve due to random and irregular folding. This extends the overall service life of the waveform seal and ultimately extends the service life of the starter electromagnetic switch assembly.

[0008] To achieve at least one of the advantages of this utility model, one advantage is that it provides a starter electromagnetic switch assembly, wherein, after power is turned on, the starter electromagnetic switch assembly pushes a drive gear of a motor to engage with a flywheel of an engine, thereby rotating the flywheel through the drive gear, and thus starting the engine.

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0026] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0027] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0028] See attached diagram. Figures 1 to 4 A preferred embodiment of the starter electromagnetic switch assembly according to this utility model will be described in detail below. After the power is turned on, the starter electromagnetic switch assembly pushes a drive gear 9001 of a motor 900 to engage with a flywheel of an engine. The flywheel rotates due to the drive gear 9001, thereby starting the engine. The starter electromagnetic switch assembly includes an electromagnetic switch body 10, a wave-shaped seal 20, and a triggering device 30. The electromagnetic switch body 10 includes a main body shell 11, an electromagnetic coil 12, a limiting ring 13, and a main body inner shell 14. The limiting ring 13 and the main body inner shell 14 are both disposed inside the main body shell 11. The main body inner shell 14 is cylindrical. The limiting ring 13 further forms a limiting through hole 1301, and the limiting ring 13 is folded towards the axis and abuts against the main body inner shell 14. The electromagnetic coil 12 is surrounded by... The inner shell 14 of the main body is provided with a core movable cavity 1401 and a trigger cavity 1403, and further with an opening 1402 communicating with the core movable cavity 1401. The core movable cavity 1401 communicates with the trigger cavity 1403 through the limiting through hole 1301. The wave-shaped sealing member 20 is provided in the opening 1402 of the inner shell 14 of the main body and is used to prevent water or dust from entering the core movable cavity 1401 from the opening 1402. The triggering device 30 is provided in the core movable cavity 1401.

[0029] Preferably, the electromagnetic switch body 10 further includes a switch cover 15, which is installed on the main body shell 11 of the electromagnetic switch body 10 and close to the opening 1402, further forming a sealed cavity 101. The wave-shaped seal 20 is disposed in the sealed cavity 101 and installed in the opening 1402 of the main body inner shell 14. Those skilled in the art will understand that although the switch cover 15 can prevent external water or dust from entering the sealed cavity 101 to a certain extent, the engine will vibrate during operation. When the electromagnetic switch body 10 is vibrated, the gap between the main body shell 11 and the switch cover 15 will increase. At this time, external water or dust will enter the sealed cavity 101 through the increased gap. Therefore, the wave-shaped seal 20 prevents water or dust in the sealed cavity 101 from further entering the iron core moving cavity 1401 through the opening 1402, enabling the starter electromagnetic switch assembly to operate smoothly in environments with heavy rain, wading, and high dust levels.

[0030] Specifically, the wave-shaped seal 20 includes a mounting ring 21 and a fixing ring 22. The inner diameter of the mounting ring 21 is larger than the inner diameter of the opening 1402. The mounting ring 21 is coaxially mounted with the inner shell 14 on one side of the opening 1402 of the inner shell 14. The fixing ring 22 of the wave-shaped seal 20 is mounted to the inner shell 14 through the mounting ring 21. The mounting ring 21 is disposed between the fixing ring 22 and the inner shell 14, so that the fixing ring 22 is more stably mounted. Therefore, when the engine vibrates during operation, the fixing ring 22 is still stably fixed to the inner shell 14 through the mounting ring 21.

[0031] Furthermore, the waveform seal 20 also includes a connecting ring 23 and a sealing sleeve 24. The fixing ring 22 is connected to the connecting ring 23 through the sealing sleeve 24, and the inner diameter of the fixing ring 22 is larger than the inner diameter of the connecting ring 23. The triggering device 30 includes a moving iron core 31, a compression member 32, a triggering structure 33, and a fork 34. The moving iron core 31 is divided into a moving part 311, a sealing member fixing part 312, and a connecting part 313. The moving part 311 is slidably disposed in the iron core movable cavity 1401 of the main body inner shell 14. The fork 34 is rotatably connected to the connecting part 313. The sealing member fixing part 312 is located between the moving part 311 and the connecting part 313. Furthermore, the sealing fixing part 312 has a sealing fixing plate 3121, the connecting ring 23 is coaxially mounted with the moving iron core 31 on the sealing fixing plate 3121 of the sealing fixing part 312, the compression member 32 is compressible and coaxially disposed with the moving iron core 31 in the iron core movable cavity 1401, and the compression member 32 is disposed between the limiting ring 13 and the moving part 311 of the moving iron core 31, the triggering structure 33 is disposed in the limiting through hole 1301 that can be pushed from the limiting through hole 1301 to the triggering cavity 1403, one end of the shift fork 34 is rotatably connected to the connecting part 313 of the moving iron core 31, and the other end of the shift fork 34 is rotatably connected to the motor 900.

[0032] Those skilled in the art will understand that when the electromagnetic coil 12 is energized, a predetermined magnetic field will be formed near the electromagnetic coil 12, causing the moving iron core 31 to be subjected to the force of the magnetic field and move a corresponding distance from the opening 1402 toward the limiting through hole 1301. At this time, the moving iron core 31 will drive the shift fork 34, which is rotatably connected to the connecting part 313 of the moving iron core 31, to move along the axial direction toward the limiting through hole 1301. Then, the other end of the shift fork 34 will move in the opposite direction to the movement of one end of the shift fork 34, and push out the drive gear 9001 of the motor 900 connected to the other end of the shift fork 34 and engage with the flywheel of the engine.

[0033] In this embodiment, the trigger structure 33 includes a trigger rod 331, a trigger piece 332, and a reset member 333. The trigger rod 331 is pushed by the moving part 311 of the moving iron core 31 and disposed in the limiting through hole 1301 of the limiting ring 13. The trigger piece 332 is connected to the trigger rod 331 and disposed in the trigger cavity 1403 of the main body inner shell 14. The reset member 333 is compressibly disposed between the trigger piece 332 and the inner wall of the main body outer shell 11. The triggering device 30 further includes a switching power supply rod 35 and a motor power supply rod 36. Both the switching power supply rod 35 and the motor power supply rod 36 are inserted into the main body housing 11, and one end of each rod is located in the trigger cavity 1403. Specifically, the other end of the switching power supply rod 35 is connected to a switching power supply via a wire, and the other end of the motor power supply rod 36 is connected to the motor via a wire. When the triggering structure 33 is pushed by the moving iron core 31 and the trigger rod 331 of the triggering structure 33 slides in the limiting through hole 1301, the trigger piece 332 of the triggering structure 33 will abut against one end of the switching power supply rod 35 and the motor power supply rod 36, forming a current path between the switching power supply rod 35 and the motor power supply rod 36, thereby enabling the motor 900 to operate. This, in turn, causes the drive gear 9001, which meshes with the flywheel of the engine, to rotate under the drive of the motor 900, ultimately starting the engine.

[0034] In another embodiment of the present invention, the trigger structure 33 includes a trigger rod 331, a trigger piece 332, and a reset member 333. The trigger rod 331 is disposed in the limiting through hole 1301 of the limiting ring 13 by being pushed by the moving part 311 of the moving iron core 31. The trigger piece 332 is connected to the moving part 311 and disposed in the trigger cavity 1403 of the inner shell 14 of the main body. The reset member 333 is compressibly disposed between the trigger piece 332 and the limiting ring 13. The triggering device 30 further includes a switching power rod 35 and a motor power rod 36. Both the switching power rod 35 and the motor power rod 36 are inserted into the main body housing 11, and one end of each of the switching power rod 35 and the motor power rod 36 is disposed in the trigger cavity 1403. Specifically, the other end of the switching power rod 35 is connected to a switching power line through a wire, and the other end of the motor power rod 36 is connected to the motor through a wire. When the triggering structure 33 is pushed by the moving iron core 31 and the trigger rod 331 of the triggering structure 33 slides in the limiting through hole 1301, the trigger piece 332 of the triggering structure 33 will abut against one end of the switching power rod 35 and the motor power rod 36, and the switching power rod 35 and the motor power rod 36 will form a current path, so that the motor 900 can operate, thereby causing the drive gear 9001 meshing with the flywheel of the engine to rotate under the drive of the motor 900, and finally realizing the starting of the engine.

[0035] Preferably, the waveform seal 20 further includes a plurality of reinforcing rings 25, which are uniformly arranged between the fixed ring 22 and the connecting ring 23 with varying inner diameters. The minimum inner diameter of the reinforcing ring 25 is greater than that of the connecting ring 23, and the maximum inner diameter of the reinforcing ring 25 is smaller than that of the fixed ring 22. The fixed ring 22, the connecting ring 23, and the reinforcing rings 25 are connected by the sealing sleeve 24. During the movement of the connecting ring 23 relative to the fixed ring 22, the sealing sleeve 24 is restricted by the reinforcing rings 25 to be folded at predetermined positions and times, preventing the sealing sleeve 24 from being damaged due to random and irregular folding. This extends the overall service life of the waveform seal 20 and ultimately extends the service life of the starter electromagnetic switch assembly.

[0036] Specifically, the reset member 333 is implemented as a spring, and the sealing sleeve 24 is provided to cover the surface of the reset member 333, thereby enhancing the integrity of the reset member 333 and making the reset member 333 more durable.

[0037] Preferably, the compression member 32 is implemented as a spring, and the sealing sleeve 24 is provided to cover the surface of the compression member 32 to enhance the integrity of the compression member 32 and make the compression member 32 more durable.

[0038] Those skilled in the art will understand that when the electromagnetic coil 12 is not energized, the moving iron core 31 is disposed in the iron core movable cavity 1401 of the inner shell 14 of the main body, and the moving part 311 of the moving iron core 31 is located in the iron core movable cavity 1401 and close to the opening 1402. At this time, the sealing sleeve 24 between the fixed ring 22 and the connecting ring 23 is stretched and forms a conical inclined surface. Due to the vibration of the engine, water or dust entering the sealing cavity 101 from the connection between the switch cover 15 and the main shell 11 will slide off the conical inclined surface. When the electromagnetic coil 12 is energized, a predetermined magnetic field will be formed near the electromagnetic coil 12, causing the moving iron core 31 to be moved a corresponding distance from the opening 1402 towards the limiting through hole 1301 under the action of the magnetic field, and pushing the trigger structure 33. During the movement of the moving iron core 31, the sealing fixing part 312 of the moving iron core 31 will drive the connecting ring 23 to move a predetermined distance along the axial direction towards the fixing ring 22. At this time, the sealing sleeve 24 will be folded to one side at a predetermined angle so that the connecting ring 23 is still stably installed on the sealing fixing plate 3121.

[0039] Preferably, the sealing plate 3121 is implemented as a disc, and the radius of the sealing plate 3121 is slightly larger than the radius of the connecting ring 23 and smaller than the radius of the fixing ring 22. This allows water or dust entering the sealing cavity 101 to fall smoothly off the conical inclined surface formed by the stretching of the sealing sleeve 24. This prevents the sealing sleeve 24 from being unable to fold at the predetermined position due to water or dust falling on the conical inclined surface of the sealing sleeve 24, which would cause the moving iron core 31 to move from the opening 1402 toward the limiting through hole 1301 and the sealing plate 312 of the sealing fixing part 312 of the moving iron core 31 to follow the moving iron core 31. Furthermore, this would prevent the sealing sleeve 24 from being damaged during the folding process.

[0040] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
