Compared with the rectifier bridge of a traditional alternator located inside the motor housing, the rear cover rectifier bridge assembly 12 is located outside, which also facilitates heat dissipation.

[0042] In one embodiment, the regulator assembly 13 includes a regulator body 131. An IC control chip is provided inside the regulator body 131, a plurality of heat sinks 132 are provided on the outer wall, and fixing holes 133 are provided at both ends.

[0044] In one embodiment, the rotor assembly 5 includes a rotor body 51 and two cooling fans 52.

An intermediate fixing ring 521 is provided on the cooling fan 52, and an intermediate fixing seat 511 corresponding to the intermediate fixing ring 521 is provided on the rotor body 51.

[0045] Working principle and beneficial effects of the above technical solution: In this embodiment, the specific structure of the rotor assembly 5 is provided. The rotor assembly 5 of this structure includes a rotor body 51 and two cooling fans 52. Specifically, the two cooling fans 52 are respectively installed at the front end and the rear end of the rotor body 51. Here, the cooling fan 52 has an intermediate fixing ring 521, and at the same time, an intermediate fixing seat 511 is designed on the rotor body 51. In this way, through the design of the cooperation between the intermediate fixing seat 511 and the intermediate fixing ring 521, the cooling fan 52 can be installed on the rotor body 51. Therefore, when the rotor body 51 rotates, it can drive the two cooling fans 52 to rotate synchronously, better discharging the generated heat to the outside, and also improving the heat dissipation efficiency of the alternator of this new energy vehicle.

[0046] In one embodiment, it further includes: a protective cover 14, and the protective cover 14 is arranged on the rear cover rectifier bridge assembly 12 and covers the regulator assembly 13.

[0047] Working principle and beneficial effects of the above technical solution: In this embodiment, the protective cover 14 is also improved. Here, the protective cover 14 is installed on the rear cover rectifier bridge assembly 12 and covers the regulator assembly 13. Through this protective cover 14, foreign matters such as mud and water from the outside cannot enter the motor housing 1, playing a role in protecting the regulator assembly 13, and can effectively prevent mud, foreign matters, etc. from entering the brush cavity of the regulator assembly 13, improving the product quality and reliability.

[0048] As Figures 6 - 13 shown, in one embodiment, it further includes: an auxiliary heat dissipation module 8. The auxiliary heat dissipation module 8 includes a support plate 801, a heat dissipation wrapping duct group 802, a heat dissipation box 803, and a pump body 804. The heat dissipation wrapping duct group 802 is wound around the outer side walls of the front cover 11 and the rear cover rectifier bridge assembly 12. The heat dissipation box 803 is arranged on the support plate 801 through a plurality of legs 805. The pump body 804 is arranged at the bottom of the heat dissipation box 803 and is electrically connected to the vehicle-mounted controller. The pump body 804 is communicated with the input end of the heat dissipation wrapping duct group 802 through a liquid supply pipe 806, and the output end of the heat dissipation wrapping duct group 802 is communicated with the heat dissipation box 803 through a return pipe 807.

[0049] Working principle and beneficial effects of the above technical solution: In order to further improve the heat dissipation efficiency of the alternator of this new energy vehicle, the specific structure of the auxiliary heat dissipation module 8 is provided in this embodiment. The auxiliary heat dissipation module 8 of this structure includes a support plate 801, a heat dissipation wrapped conduit group 802, a heat dissipation box 803, and a pump body 804. Specifically, the heat dissipation wrapped conduit group 802 is installed on the motor housing 1 here, that is, the heat dissipation wrapped conduit group 802 is wound around the outer side wall middle parts of the front cover 11 and the rear cover rectifier bridge assembly 12. By adding coolant into the heat dissipation box 803 and passing through the vehicle-mounted controller to the pump body 804 at the bottom of the heat dissipation box 803, the pump body 804 pumps the coolant in the heat dissipation box 803 into the liquid supply pipe 806, and then into the heat dissipation wrapped conduit group 802. In this way, the heat dissipated to the motor housing 1 is dissipated to the external air more quickly, thereby further improving the heat dissipation efficiency of the generator; among them, the output end of the heat dissipation wrapped conduit group 802 inputs the cold area liquid back into the heat dissipation box 803 again through the return pipe 807 to achieve recycling.

[0050] In one embodiment, a plurality of heat dissipation fins 808 are provided on the outer wall of the heat dissipation box 803, and a liquid level sensor 809 is provided inside, and the liquid level sensor 809 is electrically connected to the vehicle-mounted controller.

Here, the liquid level sensor 809 is electrically connected to the vehicle-mounted controller. Therefore, when the cold area liquid in the heat dissipation box 803 is lower than the set value, the liquid level sensor 809 alarms the vehicle-mounted controller, thereby reminding people to add cold area liquid into the heat dissipation box 803.

[0052] In one embodiment, a pressure resistance mechanism 81 is provided on the liquid supply pipe 806. The pressure resistance mechanism 81 includes an outer pressure resistance pipe 82, an inner pressure resistance pipe 83, and a plurality of intermediate pressure resistance frames 84. The inner pressure resistance pipe 83 is arranged inside the outer pressure resistance pipe 82, and a plurality of the intermediate pressure resistance frames 84 are all arranged between the outer pressure resistance pipe 82 and the inner pressure resistance pipe 83. And one end of the inner pressure resistance pipe 83 is connected to the pump body through a first quick connection mechanism 85, and the other end is connected to the heat dissipation wrapped conduit group 802 through a second quick connection mechanism. A plurality of pressure resistance elastic protrusions 821 are provided on the outer wall of the outer pressure resistance pipe 82.

[0053] Working principle and beneficial effects of the above technical solution: In order to increase the service life of the liquid supply pipe 806 and prevent the liquid supply pipe 806 from being damaged by external extrusion and unable to transport the cold zone liquid, a compressive mechanism 81 is designed on the liquid supply pipe 806 in this embodiment. The compressive mechanism 81 includes an outer compressive pipe 82, an inner compressive pipe 83, and a plurality of intermediate compressive frames 84. Specifically, the inner compressive pipe 83 is installed inside the outer compressive pipe 82, and the inner compressive pipe 83 is sleeved on the liquid supply pipe 806. At the same time, both ends of the inner compressive pipe 83 are respectively connected to the pump body and the heat dissipation wrapping duct group 802 through a first quick connection mechanism 85 and a second quick connection mechanism (not shown), completely covering the liquid supply pipe 806. At the same time, the outer compressive pipe 82 is installed outside the inner compressive pipe 83, and a plurality of intermediate compressive frames 84 are installed between the two. The plurality of intermediate compressive frames 84 provide compressive force for the entire compressive mechanism 81. A plurality of compressive elastic protrusions 821 are also designed on the outer wall of the outer compressive pipe 82, further enabling the compressive mechanism 81 to bear greater external force extrusion, protecting the liquid supply pipe 806 when the new energy vehicle encounters an accident, so that the auxiliary heat dissipation module 8 can still provide heat dissipation protection for the generator and prevent the generator from being damaged. It should be noted that a compressive mechanism 81 is also installed on the return pipe 807, protecting the return pipe 807 at the same time.

[0054] In one embodiment, the intermediate compressive frame 84 includes a first inclined sliding rod 841, a second inclined sliding rod 842, and an intermediate tension spring 843. One end of the first inclined sliding rod 841 is hinged to the inner wall of the outer compressive pipe 82, and the other end is slidably connected to the inverted T-shaped slideway 845 of the inner compressive pipe 83 through a first inverted T-shaped slide seat 844. One end of the second inclined sliding rod 842 is hinged to the inner wall of the outer compressive pipe 82, and the other end is slidably connected to the inverted T-shaped slideway 845 of the inner compressive pipe 83 through a second inverted T-shaped slide seat 846. The intermediate tension spring 843 is arranged between the first inclined sliding rod 841 and the second inclined sliding rod 842;

[0055] The first quick-connect mechanism 85 includes a quick-connect inner ring pipe 851, a quick-connect outer ring 852, and a plurality of locking components 853. The quick-connect outer ring 852 is arranged on the quick-connect inner ring pipe 851. The quick-connect inner ring pipe 851 is docked with the inner pressure-resistant pipe 83. The locking component 853 includes an inner seat 854, a locking rod 855, a locking screw 856, and a locking spring 857. A plurality of the inner seats 854 are all arranged on the outer wall of the inner pressure-resistant pipe 83. One end of the locking rod 855 is hinged to the inner seat 854. A notch groove corresponding to the locking rod 855 is arranged on the quick-connect outer ring 852. A plurality of locking screw holes are arranged on the outer wall of the quick-connect inner ring pipe 851. The locking screw 856 is inserted through the other end of the locking rod 855 and screwed into the locking screw hole. A locking spring 857 is arranged on the locking screw 856. The locking spring 857 abuts between the locking rod 855 and the locking screw 856.

[0056] Working principle and beneficial effects of the above technical solution: In this embodiment, the specific structure of the intermediate pressure-resistant frame 84 is provided. Through the intermediate pressure-resistant frame 84 of this structure, the extrusion energy of external forces can be absorbed to avoid damage to the liquid supply pipe 806. The intermediate pressure-resistant frame 84 includes a first inclined sliding rod 841, a second inclined sliding rod 842, and an intermediate tension spring 843. Specifically, one end of the first inclined sliding rod 841 is hinged to the inner wall of the outer pressure-resistant pipe 82, and the other end is slidably installed in the inverted T-shaped slideway 845 of the inner pressure-resistant pipe 83 through a first inverted T-shaped slide seat 844. Similarly, one end of the second inclined sliding rod 842 is hinged to the inner wall of the outer pressure-resistant pipe 82, and the other end is slidably installed in the inverted T-shaped slideway 845 of the inner pressure-resistant pipe 83 through a second inverted T-shaped slide seat 846. At the same time, an intermediate tension spring 843 is installed between the first inclined sliding rod 841 and the second inclined sliding rod 842. Therefore, when the outer pressure-resistant pipe 82 is subjected to an external force, the first inclined sliding rod 841 and the second inclined sliding rod 842 respectively move away from each other in the inverted T-shaped slideway 845 of the inner pressure-resistant pipe 83 through the first inverted T-shaped slide seat 844 and the second inverted T-shaped slide seat 846. In this way, the intermediate tension spring 843 is stretched under the action of the pulling force. Therefore, the intermediate tension spring 843 has the function of pulling the first inclined sliding rod 841 and the second inclined sliding rod 842 back under the action of the elastic force. Therefore, the extrusion energy of the external force can be absorbed and offset.

[0057] In this embodiment, the specific structure of the first quick-connection mechanism 85 is further provided. It can be understood that the second quick-connection mechanism has the same structure as the first quick-connection mechanism 85. Therefore, in this embodiment, the first quick-connection mechanism 85 is taken as an example. The first quick-connection mechanism 85 includes a quick-connection inner ring pipe 851, a quick-connection outer ring 852, and a plurality of locking members 853. Specifically, the quick-connection outer ring 852 is installed on the quick-connection inner ring pipe 851. The quick-connection inner ring pipe 851 is connected to the inner pressure-resistant pipe 83 through a plurality of locking members 853. The other end of the quick-connection inner ring pipe 851 is installed on the pump body. The locking member 853 includes an inner seat 854, a locking rod 855, a locking screw 856, and a locking spring 857. Specifically, a plurality of inner seats 854 are arranged on the outer wall of the inner pressure-resistant pipe 83. One end of the locking rod 855 is hinged to the inner seat 854. At the same time, a notch groove 858 is formed on the quick-connection outer ring 852. Therefore, when the locking rod 855 rotates to one side of the quick-connection inner ring pipe 851, the locking rod 855 corresponds to the notch groove 858 to prevent the locking rod 855 from shifting; at the same time, a plurality of locking screw holes 859 are arranged on the outer wall of the quick-connection inner ring pipe 851. In this way, the locking screw 856 can pass through the other end of the locking rod 855 and be screwed into the locking screw hole 859 to fix the locking rod 855 to the outer wall of the quick-connection inner ring pipe 851. Here, in order to prevent the locking screw 856 from loosening, a locking spring 857 is installed on the locking screw 856 so that the locking spring 857 abuts between the locking rod 855 and the locking screw 856. In this way, the locking screw 856 is subjected to a tensile force on the axis, thereby preventing the locking screw 856 from rotating circumferentially. At the same time, when the locking screw 856 is opened, the locking spring 857 also facilitates the opening of the locking screw 856. Thus, the first quick-connection mechanism 85 connects the quick-connection inner ring pipe 851 and the inner pressure-resistant pipe 83.

[0058] Such as Figures 13 - 16As shown, in one embodiment, a plurality of fusible mechanisms 86 are provided on the outside of the heat dissipation wrapped conduit group 802. The fusible mechanism 86 includes an outer fusible tube cap 861, a hexagonal frame 862, an inner hexagonal annular plate 863, a drain pipe 864, a fusible tube cap 865, and a plurality of auxiliary fire extinguishing members 866. The outer fusible tube cap 861 is sleeved on the heat dissipation wrapped conduit group 802. The inner hexagonal annular plate 863 is provided on the heat dissipation wrapped conduit group 802. The hexagonal frame 862 is provided on the inner hexagonal annular plate. The drain pipe 864 is provided at the corners of the hexagonal frame 862. The inner end of the drain pipe 864 passes through the inner hexagonal annular plate 863 and extends into the heat dissipation wrapped conduit group 802. The fusible tube cap 865 is provided at the outer end of the drain pipe 864 and abuts against the inner wall of the outer fusible tube cap 861. A plurality of the auxiliary fire extinguishing members 866 are evenly distributed on the inner wall of the outer fusible tube cap 861, and the auxiliary fire extinguishing members 866 are connected between two adjacent fusible tube caps 865. The auxiliary fire extinguishing member 866 includes a flexible fusible plate 867 and a plurality of fusible fire extinguishing cylinders 868. Two ends of the flexible fusible plate 867 are respectively connected to two fusible tube caps 865. A plurality of the fusible fire extinguishing cylinders 868 are provided inside the flexible fusible plate 867. The fusible fire extinguishing cylinder 868 is filled with CO 2 869.

[0059] The working principle and beneficial effects of the above technical solution: In this embodiment, in order to increase the functions of the heat dissipation wrapped conduit group 802, a plurality of fusible mechanisms 86 are provided on the outside of the heat dissipation wrapped conduit group 802. The fusible mechanism 86 includes an outer fusible tube cap 861, a hexagonal frame 862, an inner hexagonal annular plate 863, a drain pipe 864, a fusible tube cap 865, and a plurality of auxiliary fire extinguishing members 866. The outer fusible tube cap 861 is sleeved on the heat dissipation wrapped conduit group 802. The inner hexagonal annular plate 863 is installed on the heat dissipation wrapped conduit group 802 and is located inside the outer fusible tube cap 861. The hexagonal frame 862 is installed on the inner hexagonal annular plate 863. The drain pipe 864 is installed at the corners of the hexagonal frame 862. The inner end of the drain pipe 864 passes through the inner hexagonal annular plate 863 and extends into the heat dissipation wrapped conduit group 802. The fusible tube cap 865 is installed at the outer end of the drain pipe 864 and abuts against the inner wall of the outer fusible tube cap 861. A plurality of the auxiliary fire extinguishing members 866 are evenly distributed on the inner wall of the outer fusible tube cap 861, and the auxiliary fire extinguishing members 866 are connected between two adjacent fusible tube caps 865. Here, the auxiliary fire extinguishing member 866 includes a flexible fusible plate 867 and a plurality of fusible fire extinguishing cylinders 868. Two ends of the flexible fusible plate 867 are respectively connected to two fusible tube caps 865. A plurality of the fusible fire extinguishing cylinders 868 are installed inside the flexible fusible plate 867. The fusible fire extinguishing cylinder 868 is filled with CO 2 869;

[0060] Therefore, when the generator is damaged or short-circuited and catches fire, the outer fusible tube cap 861 in the fusible mechanism 86 installed on the heat dissipation wrapping duct group 802 melts when encountering fire. In this way, the internal auxiliary fire extinguishing part 866 is exposed, and the flexible fusible plate 867 and multiple fusible fire extinguishing cylinders 868 also melt. Then, the CO 2 869 inside the fusible fire extinguishing cylinder 868 is released to extinguish the fire of the generator. Further, when the fire passes through the fusible fire extinguishing cylinder 868 and then melts the outer fusible tube cap 861, after the inner end of the drain pipe 864 extends through the inner hexagonal annular plate 863 into the heat dissipation wrapping duct group 802, the coolant inside the heat dissipation wrapping duct group 802 is discharged to the outside through the drain pipe 864 under the action of the pump body to extinguish the fire, avoiding greater damage to the new energy vehicle and other components caused by the generator catching fire;

[0061] At the same time, the hexagonal frame 862 and the inner hexagonal annular plate 863 can also support the outer fusible tube cap 861 inside the outer fusible tube cap 861 to prevent the outer fusible tube cap 861 and the auxiliary fire extinguishing part 866 from being damaged when being extruded by external forces.
