Technical Field

[0001] This utility model relates to the field of starter electromagnetic switch technology, specifically to a shockproof starter electromagnetic switch. Background Technology

[0002] The starter solenoid switch is the core control component of the starter, responsible for connecting the starter's main circuit and driving the drive gear to mesh with the engine flywheel.

[0003] For example, the new type of starter solenoid switch with announcement number "CN202102978U" has a moving contact on the moving contact seat, an insulating sleeve between the moving contact seat and the moving contact, and a small hole connected to the boss. This new type of starter solenoid switch has a simple structure, is practical and convenient, reduces wear, prevents radial rotation of the coil frame, prevents coil breakage, and enables the starter to work stably and normally, improving production efficiency and product quality, and increasing product competitiveness. However, in the use of the starter solenoid switch, the starter is fixed to the engine by bolts. If the fixing bolts are loose, the vibration generated by vehicle driving and engine operation will be directly transmitted to the starter solenoid switch, and may also cause the starter armature shaft to tilt, resulting in movement and impact at the connection between the starter solenoid switch and the starter, causing abnormal noise during the use of the starter solenoid switch. Utility Model Content

[0004] The purpose of this invention is to solve the problem of abnormal noise caused by the movement and impact at the connection between the electric starter solenoid switch and the starter motor. Therefore, a shockproof starter solenoid switch is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: The design includes a shock-resistant starter solenoid switch, comprising a bent rod, to which the starter solenoid switch is fixedly connected at the rear end face of the bent rod. A mounting structure is connected to the front of the outer wall of the starter solenoid switch, and a control structure is connected to the front of the starter solenoid switch. A washer is connected to the front of the mounting structure.

[0006] This setting works as follows: Current is transmitted through the terminals to the starter solenoid switch. At this time, the attraction coil and holding coil inside the starter solenoid switch are energized, generating a combined force to attract the iron core. The iron core drives the push rod and shift fork, causing the drive gear to mesh with the flywheel. Simultaneously, the main contacts close to connect the main circuit. After the main circuit is connected, the attraction coil is short-circuited, and the holding coil maintains the contact engagement state independently. After the power is cut off, the coil is de-energized, the return spring pushes the iron core to reset, the gear disengages, and the main circuit is disconnected.

[0007] Preferably, the mounting structure includes a first ring and a second ring, the inner wall of the first ring is fixedly connected to the front of the outer wall of the starter solenoid switch, the rear end face of the first ring is in contact with the front face of the second ring, and a protective sleeve is fixedly connected to the inner wall of the second ring.

[0008] This feature: The second ring and sheath, made of fluororubber, act as a cushion and shock absorber for the starter solenoid switch, while also possessing excellent corrosion and oxidation resistance.

[0009] Preferably, the inner wall of the sheath is in contact with the outer wall of the starter solenoid switch.

[0010] This feature: Both the second ring and the protective sleeve are made of fluororubber, which protects the starter solenoid switch and prevents it from being hit by a collision.

[0011] Preferably, the front side of the first ring is fixedly connected to the rear end face of the plurality of washers.

[0012] This feature: The stainless steel washer increases the friction between the washer and the bolt / nut, preventing the bolt from loosening.

[0013] Preferably, the outer walls of both the first and second rings are machined with multiple circular openings.

[0014] This setting: After the second ring is installed, the outer wall opening should be aligned with the outer wall opening of the first ring to facilitate the bolt thread passing through the ring and connecting with the starter motor's outer wall thread.

[0015] Preferably, the control structure includes a screw and a collar, the rear end face of the screw is fixedly connected to the front terminal of the starter solenoid switch, the outer wall of the screw is threadedly connected to the inner wall of the collar, and the upper and lower sides of the collar are respectively fixedly connected with rib plates.

[0016] This feature allows the prism plate to form a point of leverage with the hand, making it easy to rotate the collar back and forth on the outer wall of the screw by pushing the prism plate left and right.

[0017] The shockproof starter solenoid switch proposed in this utility model has the following advantages: In the installation structure, the sheath is fitted onto the outer wall of the starter solenoid switch from back to front until the front of the second ring is flush with the rear of the first ring. Then, the rear of the starter solenoid switch's outer wall is inserted into the starter connection port until the first ring presses the second ring against the starter's outer wall. Subsequently, the bolt, with its right-front-to-rear thread, passes through the first ring and connects to the starter's outer wall thread. Simultaneously, the bolt nut tightens the outer wall of the washer. At this point, the second ring and the sheath, made of fluororubber, provide cushioning and shock absorption for the starter solenoid switch. They also possess excellent corrosion and oxidation resistance, preventing impact at the starter connection point and avoiding abnormal noise during use. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings: Please see Figure 1-4 In this embodiment, the shockproof starter solenoid switch includes a bent rod 1. A starter solenoid switch 4 is fixedly connected to the rear end face of the bent rod 1. Current is transmitted to the starter solenoid switch 4 through the terminal block. At this time, the attraction coil and holding coil inside the starter solenoid switch 4 are energized, generating a combined force to attract the iron core. The iron core drives the push rod and shift fork, causing the drive gear to mesh with the flywheel. At the same time, the main contacts close to connect the main circuit. After the main circuit is connected, the attraction coil is short-circuited, and the holding coil maintains the contact attraction state independently. After the power is cut off, the coil is de-energized, the return spring pushes the iron core to reset, the gear disengages, and the main circuit is disconnected. The front of the outer wall of the starter solenoid switch 4 is connected to the mounting structure 2, and the front of the starter solenoid switch 4 is connected to the control structure 3. The front of the mounting structure 2 is connected to the washer 5. The washer 5 is made of stainless steel, which can increase the friction between the washer and the bolt and nut to prevent the bolt from loosening.

[0021] The mounting structure 2 includes a first ring 201 and a second ring 202. The inner wall of the first ring 201 is fixed to the front of the outer wall of the starter solenoid switch 4. The first ring 201 is made of stainless steel. The rear end face of the first ring 201 is in contact with the front face of the second ring 202. A protective sleeve 203 is fixed to the inner wall of the second ring 202. The inner wall of the protective sleeve 203 is in contact with the outer wall of the starter solenoid switch 4. Both the second ring and the protective sleeve 203 are made of fluororubber, which protects the starter solenoid switch 4 and prevents collision with the outer wall of the starter solenoid switch 4. The front face of the first ring 201 is fixed to the rear end face of multiple washers 5. Multiple round openings are machined on the outer walls of both the first ring 201 and the second ring 202. After installation, the round openings on the outer wall of the second ring 202 should be aligned with the round openings on the outer wall of the first ring 201 to facilitate the threaded connection of the bolt through the ring and the threaded connection of the starter solenoid switch 4. In the installation structure 2, the sleeve 203 is fitted onto the outer wall of the starter solenoid switch 4 from back to front until the front of the second ring 202 is in contact with the rear of the first ring 201. Then, the rear of the outer wall of the starter solenoid switch 4 is inserted into the starter connection port until the first ring 201 presses the second ring 202 against the outer wall of the starter. Subsequently, the bolt, with its right front to rear thread, passes through the first ring 201 and connects with the circular thread on the outer wall of the starter. At the same time, the nut of the bolt presses against the outer wall of the washer 5. At this time, the second ring 202 and the sleeve 203, through their own fluororubber material, play a role in padding and shockproofing the starter solenoid switch 4. At the same time, they have good corrosion resistance and oxidation resistance, preventing the electric starter solenoid switch from moving and impacting the connection point with the starter, and avoiding abnormal noise during the use of the starter solenoid switch.

[0022] The control structure 3 includes a screw 301 and a collar 302. The rear end face of the screw 301 is fixedly connected to the front terminal of the starter solenoid switch 4. The screw 301 is made of copper to ensure normal current transmission. The outer wall of the screw 301 is threadedly connected to the inner wall of the collar 302. The collar 302 rotates back and forth through the outer wall of the screw 301 under force. The upper and lower sides of the collar 302 are respectively fixed with rib plates 303. The rib plates 303 can form a force point with the hand. Pushing the rib plates 303 left and right makes it easy to rotate the collar 302 back and forth on the outer wall of the screw 301.

[0023] Working principle: Starter solenoid switch installation: The sleeve 203 is fitted onto the outer wall of the starter solenoid switch 4 from back to front until the front of the second ring 202 is in contact with the back of the first ring 201. Then, the back of the outer wall of the starter solenoid switch 4 is inserted into the starter connection port until the first ring 201 presses the second ring 202 against the outer wall of the starter. Subsequently, the bolt threaded from right to back passes through the first ring 201 and connects with the circular thread on the outer wall of the starter. At the same time, the nut of the bolt presses against the outer wall of the washer 5. At this time, the second ring 202 and the sleeve 203, through their own fluororubber material, play a role in padding and shockproofing the starter solenoid switch 4. At the same time, they have good corrosion resistance and oxidation resistance. The washer 5 increases the friction with the bolt nut to prevent the bolt from loosening. Next, the hand contacts the outer wall of the prism plate 303, and then pushes the prism plate 303 to rotate forward on the outer wall of the screw 301 with the collar 302, so that the collar 302 disengages from the outer wall of the screw 301. Then, the wire is wound around the root of the outer wall of the screw 301, and then the prism plate 303 is pushed in the opposite direction to make the collar 302 threadedly connected to the outer wall of the screw 301, so that the collar 302 presses the wire on the outer wall of the screw 301 tightly onto the terminal in front of the starter solenoid switch 4.

[0024] Starter solenoid switch operation: When the connected wires are energized, the current is transmitted through the terminals to the starter solenoid switch 4. At this time, the attraction coil and holding coil inside the starter solenoid switch 4 are energized, generating a combined force to attract the iron core. The iron core drives the push rod and shift fork, causing the drive gear to mesh with the flywheel. At the same time, the main contacts close to connect the main circuit. After the main circuit is connected, the attraction coil is short-circuited, and the holding coil maintains the contact engagement state independently. After the power is cut off, the coil is de-energized, the return spring pushes the iron core to reset, the gear disengages, and the main circuit is disconnected.
