[0002] A methanol engine is an engine that uses methanol as the main fuel, called a methanol fuel engine. It has relatively small modifications to the original engine. On the basis of meeting the power performance of the original engine, its economy and emissions can be well improved, and it has less environmental pollution to the atmosphere. It belongs to a clean alternative fuel for vehicle engines; methanol fuel is a liquid fuel, and during its storage and transportation, we can use the storage and transportation system of petroleum fuel, so the infrastructure investment is relatively small.

[0003] Using a methanol fuel engine in an extended-range new energy vehicle to charge the battery and drive the vehicle through an electric motor. The existing methanol engine can only charge the battery pack through a fixed transmission ratio and needs to take into account the output of the motor at the same time. In the power-depleted state, the engine needs to be started for a long time to charge the battery pack and the motor to meet the driving requirements. The noise and vibration generated by the engine during operation will affect the riding experience of passengers.

Detailed Embodiment

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figure 1-7 , the present invention provides a technical solution: a power system assembly for a methanol extended-range new energy truck, including an engine 1,

[0029] a power generation assembly 2, the power generation assembly 2 is located on one side of the engine 1 and is supplemented with electricity through the engine 1.

[0030] The power generation assembly 2 includes a generator 20. One side of the generator 20 is fixedly connected with an input shaft 26. One side of the engine 1 is fixedly connected with a rotating wheel 10. The surface of the rotating wheel 10 is fixedly connected with an output shaft 18. The output shaft 18 is fixedly connected with the input shaft 26. The input shaft 26 of the generator 20 and the output shaft 18 of the engine 1 are on the same axis. When the vehicle battery is out of power, the engine 1 rotates to drive the generator 20 to charge the battery, so as to get rid of the out-of-power state.

[0031] Embodiment 2:

[0032] In the second embodiment, other structures remain unchanged. The present invention also provides that the input shaft 26 and the output shaft 18 form a 90° angle. A rotating disk 21 is provided at one end of the generator 20 away from the output shaft 18. A telescopic groove 22 is opened at a position corresponding to the output shaft 18 on the rotating disk 21. The input shaft 26 is located inside the telescopic groove 22, and a tension spring 23 is fixedly connected between the input shaft 26 and the telescopic groove 22. A mechanism for controlling the length adjustment of the output shaft 18 is provided inside the rotating wheel 10. The end faces of the output shaft 18 and the input shaft 26 are both designed with bevel gear structures and are meshed with each other. The generator 20 and the engine 1 are arranged at a 90° angle. When the engine 1 rotates, the transmission ratio to the generator 20 can be changed according to its own speed, thereby increasing the power generation efficiency of the generator 20 so that it can both provide power for the vehicle and charge the battery.

[0033] The adjusting mechanism includes a movable groove 12 which is opened on the surface of the rotating wheel 10. The output shaft 18 is located inside the movable groove 12. A circular cavity 11 is opened inside the rotating wheel 10. A centrifugal groove 13 is opened on the annular outer surface of the cavity 11. A centrifugal plate 14 is slidably connected inside the centrifugal groove 13. A centrifugal spring 15 is fixedly connected between the centrifugal plate 14 and the centrifugal groove 13. A ventilation hole 16 is penetrated and opened on one side of the centrifugal groove 13 close to the rotating wheel 10. A seal is maintained between the centrifugal groove 13 and the centrifugal plate 14. When the engine 1 drives the rotating wheel 10 to rotate at a high speed, the centrifugal plate 14 generates a centrifugal force and compresses the centrifugal spring 15 to slide outward inside the centrifugal groove 13, so that the space inside the cavity 11 is in a negative pressure state. Under the action of the negative pressure, the output shaft 18 contracts toward the rotating wheel 10. At this time, the edge of the end of the conical output shaft 18 meshes with the edge of the input shaft 26 of the generator 20. Since the output shaft 18 moves toward the engine 1, the generated space is filled downward by the input shaft 23 under the pulling of the tension spring 23, so that the inclined surface of the output shaft 18 always meshes with the inclined surface of the input shaft 26, thereby changing the transmission ratio between the engine 1 and the generator 20.

[0034] A sliding groove 24 is opened on the annular inner surface of the telescopic groove 22. A sliding block 25 is fixedly connected to the annular outer surface of the input shaft 26. The sliding block 25 is located inside the sliding groove 24, and both of them are designed with a rectangular structure to ensure the stability of the torque transmission of the input shaft 26.

[0035] A guiding groove is opened on the inner surface of the movable groove 12. A guiding block 17 is slidably connected inside the guiding groove. The guiding block 17 is fixedly connected to the output shaft 18, and both of them are designed with a rectangular structure to ensure the transmission of torque while the output shaft 18 slides.

[0036] A methanol extended-range new energy truck power system assembly processing device includes a lifting frame 3. A bearing beam 4 is fixedly connected to the upper end of the lifting frame 3.

[0037] A lifting assembly 40 is located inside the bearing beam 4 and can finely adjust the angle of the engine 1 when lifting the engine 1. Since the engine 1 is installed inside the engine compartment of the vehicle and is not a regular shape, the angle needs to be finely adjusted during installation.

[0038] The lifting assembly 40 includes a chute 41, inside which a slider 42 is slidably connected. One end of the slider 42 away from the chute 41 is fixedly connected to a lifting rod 43. An electric hoist 45 is provided at the lower end of the lifting rod 43. A threaded rod 44 is provided inside the chute 41. The number of sliders 42 is two groups, and both sliders 42 are threadedly connected to the threaded rod 44. An adjusting assembly 5 for adjusting the threaded rod 44 is provided on the upper end surface of the bearing beam 4. The engine 1 is lifted by the electric hoist 45 at the lower end of the lifting rod 43. Two electric hoists 45 are used to lift both sides of the engine 1. By changing the lifting heights of the two electric hoists 45, the angle of the engine 1 is changed to a certain extent, so as to better align with the installation area for installation.

[0039] The adjusting assembly 5 includes a motor 50, which is fixedly connected to the upper end of the bearing beam 4. The lower end of the output rod 51 of the motor 50 is designed as a bevel gear. The threaded rod 44 is composed of a first screw 441 and a second screw 442. One ends of the first screw 441 and the second screw 442 close to each other are both fixedly connected with a clutch roller 53. The inside of the clutch roller 53 is designed with a hollow structure. A clutch rod 54 is rotatably connected inside the clutch roller 53 through a bearing. A clutch plate 55 is fixedly connected to the outer surface of the clutch rod 54 inside the clutch roller 53. Electrorheological fluid is injected into the clutch roller 53. One end of the clutch rod 54 away from the clutch roller 53 is fixedly connected with a bevel gear disk 52. The bevel gear disk 52 meshes with the output rod 51 of the motor 50. The motor 50 drives the output rod 51 to rotate, and transmits the power to the threaded rod 44 through the bevel gear. By controlling the threaded rod 44 to drive the positions of the slider 42 and the lifting rod 43, the angle of the engine 1 during installation is further controlled. When it is necessary to adjust the first screw 441 or the second screw 442 separately, the electrorheological fluid inside the corresponding clutch roller 53 is electrified to become a solid, and the torque is transmitted by the clutch plate 55. The electrorheological fluid inside the other clutch roller 53 is powered off to become a liquid, so as to drive the corresponding first screw 441 or the second screw 442 to rotate, realizing separate control. If synchronous control is required, the electrorheological fluids inside the two clutch rollers 53 are directly electrified to become solids, and the torque is transmitted under the action of the clutch plate 55.

[0040] Both the slider 42 and the chute 41 are designed with a T-shaped structure. The clutch roller 53 is electrically connected to the power supply to guide the lifting rod 43.
