The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0024] First embodiment:

[0026] The present invention provides a locomotive magneto lighting coil 108 with a heat dissipation function, comprising a housing 101, a magneto body 102, a magnetic steel 103 and a heat dissipation assembly 104, wherein the heat dissipation assembly 104 comprises a rotating shell 105, a heat dissipation fan 106, a connecting column 107, a baffle 109 and an elastic member 110, wherein the rotating shell 105 comprises a housing 111, a bearing 112 and a connecting sleeve 113, wherein the housing 101 has an air inlet 115, wherein the elastic member 110 comprises a spring 116, a sliding block 117 and a connecting rod 118, wherein the elastic member 110 further comprises a guide rod 119, wherein the baffle 109 is driven by the elastic member 110 to abut against the rotating shell 105, thereby sealing the air outlet 114, and when the magneto body 102 rotates, the heat dissipation fan 106, the connecting column 107 and the rotating shell 105 are driven Rotate, so that the baffle 109 moves away from the rotating shell 105 under the action of centrifugal force, and then the air outlet 114 is opened. At this time, the cooling fan 106 rotates to blow the heat inside the rotating shell 105 and the outer shell 101 out through the air outlet 114, and then the magnetic motor body 102 and the lighting coil 108 are cooled and cooled. When the magnetic motor body 102 stops rotating, the rotating shell 105 stops rotating. At this time, the baffle 109 is reset under the action of the elastic member 110, and then the air outlet 114 is re-sealed, so as to automatically seal the air outlet 114 to prevent the entry of external dust, impurities, and rainwater, and reduce the service life of the equipment. It can be understood that the above-mentioned scheme can be used to improve the service life of the equipment, and can also be used to filter the air entering the outer shell 101.

[0027] According to the present specific embodiment, the magneto body 102 is rotatably mounted inside the shell 101, the magnet 103 is connected to the shell 101 and is located inside the shell 101, the magneto body 102 is connected to the output end of the locomotive engine, and a lighting coil 108 is distributed around the outside of the magneto body 102. There are multiple magnets 103, which are evenly arranged on the outside of the magneto body 102. The magneto body 102 is driven to rotate by the operation of the locomotive engine, so that the lighting coil 108 on the magneto body 102 can cut the magnetic field generated by the magnet 103, and then generate an induced electromotive force in the lighting coil 108, thereby generating electrical energy, which is then used for the locomotive's ignition system, lighting system and other equipment that requires electrical energy.

[0028] The rotating shell 105 is rotatably connected to the housing 101 and is located on one side of the housing 101. The heat dissipation fan 106 is fixedly connected to the magnetic motor body 102 and is located on one side of the magnetic motor body 102. The two ends of the connecting column 107 are respectively connected to the rotating shell 105 and the heat dissipation fan 106. The connecting column 107 is located on the side of the heat dissipation fan 106 away from the magnetic motor body 102. The elastic member 110 is arranged on the rotating shell 105. The baffle 109 is slidably connected to the rotating shell 105 through the elastic member 110. The baffle 109 and the elastic member 110 are connected to the rotating shell 105. 0 is provided with a plurality of them, and they are evenly distributed on the rotating shell 105. The rotating shell 105 is provided with an air outlet 114 on one side close to the baffle 109. The baffle 109 is fitted with the rotating shell 105 under the action of the elastic member 110, thereby sealing the air outlet 114. When the magnetic motor body 102 rotates to generate electricity, the magnetic motor body 102 simultaneously drives the heat dissipation fan 106 to rotate, and the heat dissipation fan 106 drives the connecting column 107 and the rotating shell 105 to rotate, thereby driving the plurality of baffles 109 to rotate, so that the baffles 109 are subjected to the action of centrifugal force. Under the action of centrifugal force, the baffles The plate 109 overcomes the elastic force of the elastic member 110 and gradually separates from the rotating shell 105, at which time the air outlet 114 is opened; at the same time, due to the rotation of the heat dissipation fan 106, the air inside the rotating shell 105 and the outer shell 101 can be discharged through the air outlet 114, thereby taking away the heat generated by the magnetic motor body 102 and the lighting coil 108 when they are working, thereby achieving the purpose of dissipating heat for the magnetic motor body 102 and the lighting coil 108; when the locomotive engine stops rotating, the heat dissipation fan 106, the connecting column 107 and the rotating shell 105 stop rotating, at which time the baffle 109 is lost. The centrifugal force is removed, and the rotating shell 105 is re-fitted under the elastic force of the elastic component 110 to seal the air outlet 114, thereby preventing external dust, impurities or rainwater from entering the rotating shell 105 and the outer shell 101 and affecting the magnetic motor body 102. The present invention improves the heat dissipation effect of the magnetic motor body 102 and the lighting coil 108 through the rotation of the cooling fan 106. At the same time, after the baffle 109 loses the centrifugal force, it can automatically reset under the action of the elastic component 110, thereby preventing dust, debris and rainwater from entering the inner part of the outer shell 101 and reducing the service life of the equipment.

[0029] Secondly, the bearing 112 is rotatably connected to the outer shell 101 and is arranged on the outer shell 101; the connecting sleeve 113 is fixedly connected to the bearing 112 and is located on the inner side of the bearing 112; the shell 111 is fixedly connected to the connecting sleeve 113 and is fixedly connected to the connecting column 107 and is located on one side of the connecting sleeve 113; the air outlet 114 is arranged on the shell 111, and the bearing 112 is used to reduce the resistance of the rotating shell 105 during rotation, so that the cooling fan 106 can drive the rotating shell 105 to rotate more smoothly, thereby improving the heat dissipation efficiency. At the same time, the bearing 112 also enhances the connection stability between the rotating shell 105 and the outer shell 101, thereby extending the service life of the equipment.

[0030] At the same time, the air inlet hole 115 is arranged on one side of the shell 101 and passes through the shell 101; there are multiple air inlet holes 115 and they are evenly distributed on the shell 101. Through the air inlet holes 115, external cold air can enter the shell 101 through the air inlet holes 115, so as to dissipate heat for the magnetic motor body 102 and the lighting coil 108. It should be noted that, for the convenience of description, the above text defines "air inlet hole 115" and "air outlet hole 114", as well as the specific rotation direction of the cooling fan 106, but in actual applications, the hole originally defined as "air inlet hole 115" may need to assume the function of "air outlet", and the hole originally defined as "air outlet hole 114" may need to be changed to "air inlet". Similarly, the rotation direction of the cooling fan 106 can also be adjusted as needed to ensure that heat can be effectively taken away from the heat source and discharged.

[0031] In addition, the connecting rod 118 is slidably connected to the shell 111, and is fixedly connected to the baffle 109 and is located on one side of the baffle 109; the sliding block 117 is fixedly connected to the connecting rod 118 and is located on the side of the connecting rod 118 away from the baffle 109; the two ends of the spring 116 are respectively connected to the sliding block 117 and the shell 111, and the spring 116 is sleeved on the connecting rod 118; the spring 116 provides elastic force to the baffle 109, so that the baffle 109 can fit tightly with the rotating shell 105 when not subjected to centrifugal force, thereby sealing the air outlet 114, and when the magnetic motor body 102 rotates to drive the cooling fan 106 and the rotating shell 105 to rotate, the baffle Plate 109 is moved away from the rotating shell 105 by the centrifugal force. At this time, the baffle 109 drives the connecting rod 118 and the sliding block 117 to move, so that the sliding block 117 squeezes the reset spring 116. At this time, the air outlet 114 is opened, and the airflow generated by the cooling fan 106 can be discharged smoothly to dissipate the heat generated by the magnetic motor body 102 and the lighting coil 108. At this time, the spring 116 accumulates elastic potential energy. When the rotating shell 105 stops rotating, the baffle 109 loses the effect of centrifugal force. At this time, the spring 116 releases elastic potential energy, thereby driving the sliding block 117 to reset. The sliding block 117 drives the connecting rod 118 and the baffle 109 to reset, and then re-seals the air outlet 114.

[0032] Finally, the guide rod 119 is fixedly connected to the baffle 109 and slidably connected to the shell 111, and is located on the side of the shell 111 close to the connecting rod 118; two guide rods 119 are provided on one baffle 109, and the shell 111 is provided with a guide groove that cooperates with the guide rod 119. The movement of the baffle 109 is guided by the guide rod 119, so that the baffle 109 can only move along the length direction of the guide rod 119, thereby improving the stability of the baffle 109 when moving.

[0033] When the locomotive magneto lighting coil 108 with heat dissipation function of the present embodiment is used, the locomotive engine will drive the magneto body 102 to rotate when it is working, and then drive the lighting coil 108 to cut the magnetic field generated by the magnetic steel 103, so as to generate an induced electromotive force in the lighting coil 108, and the electric energy will then be used for the ignition system, lighting system and other equipment requiring electric energy of the locomotive; at the same time, the rotation of the magneto body 102 will also drive the heat dissipation fan 106 to rotate together, and the heat dissipation fan 106 is connected to the rotating shell 105 through the connecting column 107, so the rotation of the heat dissipation fan 106 will further drive the rotating shell 105 and the multiple baffles 109 and the elastic member 110 arranged thereon to rotate together; during the rotation process, the baffle 109 is acted upon by the centrifugal force, gradually overcomes the elastic force of the elastic member 110, and separates from the rotating shell 105, at which time The air outlet 114 is opened; as the cooling fan 106 continues to rotate, the hot air inside the rotating shell 105 and the outer shell 101 is discharged through the opened air outlet 114, and new cold air is sucked in from the air inlet 115; thereby continuously taking away the heat generated by the magneto body 102 and the lighting coil 108 and discharging it to the outside, thereby achieving the purpose of efficient heat dissipation; when the locomotive engine stops working, the magneto body 102, the cooling fan 106 and the rotating shell 105 will also stop rotating. At this time, the baffle 109 is no longer affected by the centrifugal force, but is re-fitted with the rotating shell 105 under the elastic force of the elastic member 110 to seal the air outlet 114, so that external dust, impurities and rainwater are blocked outside the outer shell 101, avoiding damage to the magneto body 102 and the lighting coil 108.

The shell 111 of this embodiment has a sealing groove 201 , and the heat dissipation component 104 also includes a first filter 202 , a second filter 203 and a limiting boss 204 .

[0036] For this specific embodiment, the sealing groove 201 is arranged on a side of the shell 111 close to the baffle 109, and the sealing groove 201 cooperates with the baffle 109; when the baffle 109 is reset under the action of the elastic member 110, the baffle 109 is embedded in the sealing groove 201, effectively preventing external dust, impurities and rainwater from entering the rotating shell 105 and the outer shell 101 through tiny gaps, further improving the protection performance of the equipment.

[0037] The first filter 202 is fixedly connected to the outer shell 101 and is located on a side of the outer shell 101 close to the shell 111 and is sleeved on the shell 111 ; the first filter 202 prevents external dust and debris from entering the outer shell 101 through the air outlet 114 .

[0038] Secondly, the second filter 203 is fixedly connected to the outer shell 101 and is located on a side of the outer shell 101 close to the air inlet 115; the air entering the air inlet 115 is filtered by the second filter 203 to prevent dust and impurities from entering the interior of the outer shell 101 through the air inlet 115.

[0039] At the same time, the limiting boss 204 is fixedly connected to the shell 111 and is located inside the shell 111; the movement of the sliding block 117 is limited by the limiting boss 204, and the sliding block 117 stops moving when it abuts against the limiting boss 204, thereby stopping the movement of the baffle 109. At this time, the air outlet 114 is in an open state, ensuring that the baffle 109 can be stably opened to a predetermined position under the action of centrifugal force, thereby avoiding the baffle 109 from being too open and interfering with the first filter 202.
