The starter can convert the electrical energy of the battery into mechanical energy, drive the engine flywheel to rotate, and achieve the starting of the engine. The starter uses three components to achieve the entire starting process: the DC motor introduces the current from the battery and makes the drive gear of the starter generate mechanical movement.

Detailed implementation mode
[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation modes.
[0023] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown in the figure, the present utility model provides a waterproof starter, which includes a starter drive housing 1. A protruding semi-circular cover 2 is fixedly installed on the front side of the starter drive housing 1. A connection box 3 is fixedly connected through the top of the starter drive housing 1. An electromagnetic coil housing 4 is fixedly connected through the top of the connection box 3. An installation mechanism 5 is fixedly installed on the front side of the outer wall of the starter drive housing 1. A rotor 11 is arranged at the rear side of the inner cavity of the starter drive housing 1. A plurality of stator permanent magnets 12 are fixedly installed in an annular array on the rear side of the inner ring of the starter drive housing 1. A drive rotating rod 13 is fixedly installed at the center of the front end of the rotor 11. A protruding suspension plate 21 is fixedly installed on the front side of the bottom of the protruding semi-circular cover 2. The front end of the drive rotating rod 13 is movably connected to the rear side of the protruding suspension plate 21. A second waterproof fixing ring 15 is fixedly installed on the frontmost side of the inner ring of the starter drive housing 1. A first waterproof fixing ring 14 is arranged at the rear side of the second waterproof fixing ring 15. The first waterproof fixing ring 14 is fixedly connected to the inner ring of the starter drive housing 1. A threaded wall 131 is formed on the rear side of the outer wall of the drive rotating rod 13. A threaded ring 132 is threadedly installed on the outer wall of the threaded wall 131. A bearing ring 133 is fixedly installed on the outer wall of the threaded ring 132. A connection ring 134 is fixedly installed on the front side of the threaded ring 132. A limit ring 135 is movably installed on the front side of the connection ring 134. A telescopic cylinder 136 is fixedly installed on the front side of the limit ring 135. A gear 137 is movably installed on the front side of the outer wall of the telescopic cylinder 136. The inner rings of the connection ring 134, the limit ring 135, and the telescopic cylinder 136 are all in contact with the outer wall of the drive rotating rod 13. The inner ring of the gear 137 is fixedly connected to the outer wall of the drive rotating rod 13. An annular groove 141 is formed in the inner ring of the first waterproof fixing ring 14. A rubber sealing ring 142 is clamped in the inner ring of the annular groove 141. The inner ring of the rubber sealing ring 142 is in interference fit with the outer wall of the telescopic cylinder 136. Sealing rings 151 are fixedly installed on both the front and rear sides of the second waterproof fixing ring 15. The inner rings of the two sealing rings 151 are both in contact with the outer wall of the telescopic cylinder 136;
[0024] When the threaded ring 132 is pushed forward, by using the threaded connection between the threaded ring 132 installed on the inner ring of its inner ring and the threaded wall 131, the threaded wall 131 can drive the gear 137 to rotate slowly, and by using the connection ring 134, the limit ring 135, and the telescopic cylinder 136 to squeeze and move forward until the gear 137 meshes with the generator flywheel. And when just meshed, the rotor can be powered on. By using the rotation of the stator permanent magnet 12 to drive the driving rotating rod 13 to rotate, the threaded ring 132 cannot move forward under the limitation of the bearing ring 133, so that the threaded wall 131 drives the threaded ring 132 to rotate at a high speed in the bearing ring 133, so that the gear 137 drives the engine flywheel to rotate and start the engine. And when the telescopic cylinder 136 is squeezed by the forward movement, it will use the rolling of the rubber sealing ring 142 in the annular groove 141 to improve the smoothness, and at the same time use the interference fit between the rubber sealing ring 142 and the outer wall of the telescopic cylinder 136 to improve the sealing and waterproof performance. At the same time, it is further combined with the sealing ring 151 installed before and after the waterproof fixing ring two 15 on the front side to further improve the waterproof performance of the starter gear when it moves out.
[0025] As Figure 5 shown, a connecting long rod 31 is fixedly installed between the left and right sides of the inner wall of the connection box 3. An adjustable connecting rod 32 is movably installed on the outer wall of the connecting long rod 31. The bottom end of the adjustable connecting rod 32 is movably connected to the top of the threaded ring 132. A fixed partition 49 is fixedly installed in the middle of the inner ring of the electromagnetic coil housing 4. A return spring 41 is fixedly installed on the front side of the fixed partition 49. A limit disc 42 is fixedly installed on the front side of the return spring 41. A connecting rod 43 is fixedly installed at the center of the front side of the limit disc 42. The front end of the connecting rod 43 is movably connected to the top end of the adjustable connecting rod 32. A metal telescopic column 44 is fixedly installed on the rear side of the limit disc 42. The metal telescopic column 44 is located inside the return spring 41. The rear end of the metal telescopic column 44 penetrates to the rear side of the fixed partition 49 and is fixedly installed with an extension rod 45. An electromagnetic coil 47 is fixedly installed on the rear side of the inner ring of the return spring 41. The metal telescopic column 44 and the extension rod 45 are located inside the electromagnetic coil 47. A power connection box 48 is fixedly installed on the rear side of the return spring 41. The rear end of the extension rod 45 penetrates into the inner cavity of the power connection box 48 and is fixedly installed with a copper disc 46. Two power supply ports 481 penetrating into the inner cavity of the power connection box 48 are fixedly installed on the rear side of the power connection box 48. The two power supply ports 481 are respectively positive and negative electrodes. The rear side of the copper disc 46 is in contact with the front ends of the two power supply ports 481. The output ends of the power supply ports 481 are electrically connected to a power supply wire 482. The power supply wire 482 is used to supply power to the rotor 11;
[0026] When there is water in the engine to start the starter, the current transmitted by the key will energize the electromagnetic coil 47 in the electromagnetic coil housing 4, thereby generating a magnetic field in the inner ring of the electromagnetic coil 47, which will be attracted and moved toward the metal telescopic column 44 made of metal material to the rear side, thereby driving the limit plate 42 to compress the return spring 41, so that the connecting telescopic rod 32 can be stretched and the threaded ring 132 can be pushed forward by utilizing the movable connection between the connecting rod 43 and the connecting long rod 31. When the threaded ring 132 is pushed to a point where it can no longer be pushed, the copper plate 46 at the rear end of the extension rod 45 will also contact the two power supply ports 481, so that the current passes through the power supply wire 482 to start the rotor 11 to rotate. When the power supply to the electromagnetic coil 47 is disconnected, the limit plate 42 can be reset forward under the rebound of the return spring 41, thereby driving the connecting telescopic rod 32 to maintain a vertical state and reset, thereby pulling the gear 137 to reset.
[0027] like Figure 6 As shown, the mounting mechanism 5 includes a fixing ring 51, which is fixedly mounted on the outer wall of the starter drive housing 1. A mounting plate 52 is fixedly mounted on the opposite surface of the outer wall of the fixing ring 51. The two mounting plates 52 are made of metal. Both mounting plates 52 are provided with bolt holes 53 that pass through the two mounting plates 52. Sealing covers 54 are movably mounted on the rear sides of the two mounting plates 52. The two sealing covers 54 are respectively located on one side of the two bolt holes 53. A rubber pad 55 is fixedly mounted on one side of the two sealing covers 54 close to the mounting plates 52. Strong magnets 56 are fixedly mounted on one side of the outer wall of the two sealing covers 54. The two strong magnets 56 are respectively adsorbed to the rear sides of the two mounting plates 52, and after adsorption, the rubber pads 55 overlap the rear sides of the mounting plates 52.
[0028] When installing the starter, the two mounting plates 52 on the outer wall of the fixing ring 51 are directly fixed to one side of the flywheel of the engine by passing bolts through the bolt holes 53. Then the sealing cover 54 can be directly covered on the bolts so that the bolts are in the inner cavity of the sealing cover 54. At the same time, after the sealing cover 54 is combined, the strong magnet 56 will be tightly adsorbed to the back side of the mounting plate 52, and the rubber pad 55 is used to improve the sealing between the sealing cover 54 and the mounting plate 52 after it is combined, to prevent the bolts from rusting due to long-term contact with water and becoming difficult to disassemble.
[0029] The following is a detailed description of the working principle of the waterproof starter.
[0030] like Figures 1-6As shown, when there is water in the engine to start the starter, the current transmitted by the key will energize the electromagnetic coil 47 in the electromagnetic coil housing 4, thereby generating a magnetic field in the inner ring of the electromagnetic coil 47, which attracts and moves the metal telescopic column 44 toward the rear side, thereby driving the limit plate 42 to compress the return spring 41, so that the connecting rod 43 and the connecting long rod 31 are connected flexibly, so that the connecting telescopic rod 32 can be extended and the threaded ring 132 can be pushed forward at the same time. When the threaded ring 132 is pushed to the point where it can no longer be pushed, the copper plate 46 at the rear end of the extension rod 45 will also contact the two power supply ports 481, so that the current The rotor 11 is started to rotate through the power supply wire 482. When the threaded ring 132 is pushed forward, the threaded ring 132 installed on the inner ring of the inner ring is connected to the threaded wall 131, so that the threaded wall 131 can drive the gear 137 to rotate slowly, and the connecting ring 134, the limiting ring 135, and the telescopic cylinder 136 are used to squeeze and move forward until the gear 137 is engaged with the generator flywheel. When the engagement is just made, the rotor can be energized and the rotation of the stator permanent magnet 12 is used to drive the driving rod 13 to rotate. The threaded ring 132 cannot move forward due to the limit of the bearing ring 133, so that the threaded wall 131 drives the threaded ring 137 to rotate slowly. The ring 132 rotates at high speed in the bearing ring 133, so that the gear 137 drives the engine flywheel to rotate and start the engine. When the telescopic cylinder 136 is squeezed forward, the rubber sealing ring 142 in the annular groove 141 is used to roll to improve the smoothness. At the same time, the interference fit between the rubber sealing ring 142 and the outer wall of the telescopic cylinder 136 is used to improve the sealing and waterproof performance. At the same time, the sealing ring 151 installed before and after the front waterproof fixing ring 15 is used to further improve the waterproof performance of the starter gear when it is moved out. When the power supply to the electromagnetic coil 47 is disconnected, the limit plate 42 can return forward under the rebound of the return spring 41. The connecting telescopic rod 32 is reset to maintain a vertical state, thereby pulling the gear 137 to reset. At the same time, when installing the starter, the two mounting plates 52 on the outer wall of the fixing ring 51 are directly fixed to one side of the flywheel of the engine by passing bolts through the bolt holes 53. Then the sealing cover 54 can be directly covered with the bolts so that the bolts are in the inner cavity of the sealing cover 54. At the same time, after the sealing cover 54 is combined, the strong magnet 56 will be tightly adsorbed with the back side of the mounting plate 52, and the rubber pad 55 is used to improve the sealing between the sealing cover 54 and the mounting plate 52 after it is combined, so as to prevent the bolts from rusting when exposed to water for a long time and becoming difficult to disassemble.
[0031] While the present invention has been generally described above, it is readily apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are intended to be within the scope of protection of the present invention.
