Description

Technical Field

[0001] The present invention belongs to the technical field of power units, and more specifically, particularly relates to a compact vehicle-mounted intelligent power unit. Background Art

[0002] A power unit is a small power device that integrates multiple components such as a motor (or other power source), a pump, a valve, a fuel tank, etc. Its main function is to convert some form of energy (such as electrical energy, mechanical energy, etc.) into hydraulic energy or pneumatic energy to provide power support for the operation of mechanical equipment.

[0003] Therefore, the current power unit is found to have at least the following technical problems:

[0004] 1. The existing power unit layout has low space utilization, and usually uses the noise reduction components of the engine or water cooling to reduce noise. However, when the engine or water cooling is working, it will cause certain vibrations due to the reciprocating formation of the piston and the high-speed circulation of the water cooling. This vibration is easy to be superimposed inside the power unit box, which leads to the existing power unit being noisy when used;

[0005] 2. When in use, the existing power unit generally relies on its own cooling system for heat dissipation, and cannot perform additional heat dissipation on the original basis, which leads to overheating problems after long-term use, thereby reducing the efficiency of the power unit;

[0006] 3. During operation, the external protection measures of the existing power unit usually only have a single protection function. At the same time, the box outside the power unit is generally provided with an air inlet to meet the ventilation requirements of the equipment operation.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the present invention, when the filter plate extends from the inside of the first slide slot toward the direction of the travel switch, the movement of the filter plate will drive the second rack to move, so that the second rack can actively mesh with the second gear, so that the second gear generates a radial force to drive the circular rotating shaft and the air induction plate to rotate, so that the two sides of the box body can assist in unfolding an air induction plate with an inclined angle. Therefore, when the inclined air guide plate takes in air, since the inclined air guide plate is square as a whole, part of the wind will flow on both sides of the side box cover due to collision. By arranging the two sides of the box body to assist in unfolding an air shield with an inclined angle, the ventilation efficiency inside the box body can be further improved, and the heat dissipation effect can be further improved.

[0019] In the present invention, by arranging a silencer base at the center of the interior of the power unit cabin, and arranging the first engine and the second engine which generate relatively large noise during operation on both sides of the silencer base, the silencer base can be used to absorb and block the noise generated by the operation of the first engine and the second engine. At the same time, the generator radiator body and the generator radiator expansion water tank are arranged above the silencer base, and then the silencer base can be used to a certain extent to reflect and absorb the coolant flow sound, the fan rotation sound, etc. generated during the operation of the generator radiator body and the generator radiator expansion water tank, so that the overall structure is compact. At the same time, this compact layout also helps to reduce the path and range of noise propagation, avoid excessive reflection and superposition of noise in the power unit cabin, thereby further reducing the noise level radiated outward from the entire power unit cabin, and thus achieving a certain sound insulation effect.

[0020] In the present invention, by setting an auxiliary heat dissipation structure, the staff can turn on the servo motor to indirectly drive the first gear and mesh with the first rack, so that the first gear can generate a radial force on the first rack on the protective plate and the filter plate. Since the first gear is located on both sides of the protective plate and the filter plate, the first gear can drive the protective plate and the filter plate to extend or retract respectively by changing the rotation, so that when it rains, the staff can move the protective plate to the side groove to avoid rainwater from entering the power unit cabin and causing a certain impact, and when the weather is good, the staff can move the filter plate to the side groove to increase the air inlet area of ​​the power unit cabin for heat dissipation, thereby improving the heat dissipation efficiency;

[0021] In the present invention, by arranging a box body and a side box cover outside the power unit cabin body, not only the overall protection and heat dissipation of the power unit cabin body can be enhanced, but also the box body and the side box cover can cooperate with the silencer base to further achieve the effect of isolating sound;

[0022] In the present invention, by optimizing the structure and layout of the device, engine radiators are symmetrically arranged inside the power unit cabin, and two engine radiators are located on the side walls of the generator body, so that the overall structure and layout can be optimized, so that the structure is compact and the heat dissipation is reasonable, thereby achieving a highly integrated and lightweight power unit, thereby effectively solving the problems of poor heat dissipation and low output power during the operation of the whole vehicle, and improving efficiency;

By setting the auxiliary heat dissipation structure, the staff can turn on the servo motor 23 to indirectly drive the first gear 27 and mesh with the first rack 21, so that the first gear 27 can generate a radial force on the first rack 21 on the protective plates 18 and the filter plates 19. Since the first gear 27 is located at the protective plate 18, the first gear 21 on the filter plates 19 can generate a radial force on the first rack 21 on the protective plate 18 and the filter plates 19. On both sides of the guard plate 18 and the filter plate 19, the first gear 27 can drive the guard plate 18 and the filter plate 19 to extend or retract respectively by changing the rotation, so that when it rains, the staff can move the guard plate 18 to the side groove 12 to prevent rainwater from entering the power unit cabin 42 and causing certain impacts, and when the weather is good, the staff can move the filter plate 19 to the side groove 12 to increase the air inlet area of ​​the power unit cabin 42 for heat dissipation, thereby improving the heat dissipation efficiency, and by setting the rectangular groove 16, when the staff turns on the servo motor 23 to drive the guard plate 18 and the filter plate 19 to move, it can drive the rectangular groove 16 of the sliding block 17 connected to the guard plate 18 and the filter plate 19 to slide, thereby providing additional limit and increasing stability.

A first silencer exhaust pipe 43 and a second silencer exhaust pipe 44 are provided on the surface of the silencer base 62. By arranging the box body 11 and the side box cover 35 outside the power unit cabin 42, not only the overall protection and heat dissipation of the power unit cabin 42 can be enhanced, but also the box body 11 and the side box cover 35 can cooperate with the silencer base 62 to further achieve the effect of isolating sound.

[0047] Each first rack 21 is parallel to the middle through slot 15, and a placement slot 22 is symmetrically opened inside the box body 11. A servo motor 23 is fixedly installed inside the two placement slots 22. A rotating rod 24 is rotatably installed inside the two placement slots 22. The two rotating rods 24 are partially extended through the placement slots 22 to the top of the middle through slot 15 for rotation. A worm gear 25 is fixedly installed on the circumferential surface of the two rotating rods 24. The two worm gears 25 are located inside the placement slots 22. Worm teeth 26 are fixedly installed on the output shafts of the two servo motors 23. The two worm teeth 26 are meshed with the worm gear 25. The circumferential surfaces of the two rotating rods 24 are fixedly installed. There are first gears 27, and two first gears 27 are both located inside the middle through groove 15. The two first gears 27 are meshed and installed with the first racks 21 on the protective plate 18 and the filter plate 19. When the servo motor 23 is started, the output shaft of the servo motor 23 drives the worm gear 26 to rotate and mesh with the worm wheel 25, so that the worm wheel 25 generates a radial force to drive the rotating rod 24 and the first gear 27 to rotate, and then the special transmission mode of the worm wheel can be used for self-locking, thereby improving the stability of the protective plate 18 and the filter plate 19 when moving and the sealing of the protective plate 18, the filter plate 19 and the side box cover 35 when they are fitted.

[0048] The frames of the two filter plates 19 are provided with grooves 28, and the inner walls of the two grooves 28 are fixedly installed with second racks 29, and the two second racks 29 are located on the side wall away from the first rack 21 installed on the filter plate 19. The side walls of the box body 11 are symmetrically fixedly installed with fixed plate groups 31, and a circular rotating shaft 32 is rotatably installed between each fixed plate group 31. The circumferential surfaces of the two circular rotating shafts 32 are fixedly installed with second gears 33, and the two second gears 33 are parallel to the second racks 29. The two second gears 33 are meshed with the second racks 29. The circumferential surfaces of the two circular rotating shafts 32 are fixedly installed with air induction plates 34, and the two air induction plates 34 are located outside the circular rotating shafts 32. The two air induction plates 34 are located on the outside of the filter plate 19. When the filter plate 19 is moved from When the first slide groove 13 extends toward the direction of the travel switch 38, the movement of the filter plate 19 will drive the second rack 29 to move, so that the second rack 29 can actively engage with the second gear 33, so that the second gear 33 generates a radial force to drive the circular rotating shaft 32 and the air guide plate 34 to rotate, so that the two sides of the box body 11 can assist in unfolding an air guide plate 34 with an inclined angle. Therefore, when the inclined air guide plate 37 takes in air, since the inclined air guide plate 37 is square as a whole, part of the wind will flow on both sides of the side box cover 35 due to collision. By setting up an auxiliary wind shield with an inclined angle on both sides of the box body 11, the ventilation efficiency inside the box body 11 can be further improved, and the heat dissipation effect can be further improved.

[0049] A side box cover 35 is fixedly installed on the surface of the box body 11, and a plurality of air inlet slots 36 are opened inside the side box cover 35. An inclined air guide plate 37 is provided on the side wall of each air inlet slot 36. A travel switch 38 is fixedly installed on the inner wall of the two first slide slots 13 and the second slide slot 14 (the travel switch 38 can be used to limit the travel range of the output electrical), and each travel switch 38 is adapted to the protective plate 18 and the filter plate 19. A PLC controller 39 is provided on the side wall of the box body 11, and a temperature control unit is provided inside the PLC controller 39. By arranging a cold radiator and a high-pressure fan on the engine radiator 46 and arranging a PLC controller 39 outside the box body 11, and using the temperature sensor monitoring system of the engine radiator 46 for control, the temperature sensor monitoring system can monitor the temperature of the cooling medium in the engine radiator 46, and convert it into a voltage signal and input it into the PLC controller 39. According to the received electrical signal, the speed of the electronic fan can be adjusted in real time, and the fan speed can be accurately controlled and adjusted by the real-time temperature of the cooling medium, thereby realizing intelligent heat dissipation control.

[0050] The lower ends of the box body 11 and the side box cover 35 are symmetrically fixed with support legs 41. By setting the inclined wind guide plate 37, it can be avoided that when it rains, wind enters one side of the inclined wind guide plate 37 and causes rainwater to enter the power unit cabin 42 and cause an impact.

[0051] The first muffler exhaust pipe 43 and the second muffler exhaust pipe 44 are both partially located outside the power unit cabin 42. A high-power structure is symmetrically arranged inside the power unit cabin 42. The high-power structure includes a generator body 45. An engine radiator 46 is symmetrically arranged inside the power unit cabin 42. The two engine radiators 46 are located on the side wall of the generator body 45. The engine radiators 46 are controlled by the temperature control unit inside the PLC controller 39. A first engine 47 and a second engine 57 are respectively arranged inside the power unit cabin 42. The first engine 47 and the second engine 57 are symmetrically arranged inside the power unit cabin 42. The two engines 57 are both located on both sides of the silencer base 62, and the upper ends of the two first engines 47 are provided with drivers 48.

[0052] The inner wall of the power unit cabin 42 is symmetrically threaded with a first air filter 49 and a second air filter 56. The inner wall of the power unit cabin 42 is threaded with a fuel coarse filter 58 (which can separate and filter impurities and moisture in the fuel), a fuel fine filter 59 and a low-pressure electric pump 61. The fuel coarse filter 58, the fuel fine filter 59 and the low-pressure electric pump 61 are all on the same side as the second air filter 56. A generator controller 51 is fixedly installed on the bracket at the upper end of the two generator bodies 45. The upper ends of the two generator controllers 51 are respectively provided with a first preheating relay 52 and a second preheating relay 55. The upper ends of the silencer base 62 are respectively provided with a generator radiator body 53 and a generator radiator expansion water tank 54. By arranging the silencer base 62 at the center of the power unit cabin 42 and arranging the first engine 47 and the second engine 57 that cause greater noise during operation on both sides of the silencer base 62, the silencer base 62 can be used to absorb and block the noise generated by the operation of the first engine 47 and the second engine 57.

At the same time, this compact layout also helps to reduce the path and range of noise propagation, avoid excessive reflection and superposition of noise in the power unit cabin 42, thereby further reducing the noise level radiated outward by the entire power unit cabin 42, thereby achieving a certain sound insulation effect, and by optimizing the structure and layout of the device, engine radiators 46 are symmetrically arranged inside the power unit cabin 42, and two engine radiators 46 are located on the side walls of the generator body 45, so that the overall structure and layout can be optimized, making the structure compact and the heat dissipation reasonable, thereby achieving a highly integrated and lightweight power unit, thereby effectively solving the problems of poor heat dissipation and low output power during the operation of the whole vehicle, and improving efficiency.

[0053] Working principle:

[0054] In the first step, when the power unit cabin 42 inside the box body 11 is working normally, the air inhaled by the power unit cabin 42 for heat dissipation is sucked into the air inlet slot 36 through the inclined air guide plate 37 and enters the inside of the box body 11. When the power unit cabin 42 needs auxiliary heat dissipation, the staff can turn on the servo motor 23 at this time, so that the output shaft of the servo motor 23 drives the worm gear 26 to rotate and mesh with the worm gear 25, so that the worm gear 25 generates a radial force to drive the rotating rod 24 and the first gear 27 to rotate counterclockwise. At this time, the first gear 27 will mesh with the first rack 21 on the protective plate 18 and the filter plate 19, so that the first gear 27 can generate a radial force on the first rack 21 on the protective plate 18 and the filter plate 19, so that the protective plate 18 drives the protective plate 18 to drive ... The sliding block 17 connected to the plate 18 slides in the second slide groove 14 and the rectangular groove 16 toward the side close to the travel switch 38. At the same time, the filter plate 19 will drive the sliding block 17 connected to the filter plate 19 to slide in the first slide groove 13 and the rectangular groove 16 toward the side away from the travel switch 38, so that the protective plate 18 is retracted into the box body 11, and the filter plate 19 extends into the side through groove 12. When the protective plate 18 slides to the end in the second slide groove 14, the protective plate 18 hits the travel switch 38, so that the travel switch 38 sends a signal through the PLC controller 39 to control the servo motor 23 to stop moving. At this time, the surface of the filter plate 19 will fit with the side wall of the side box cover 35, so that two additional air inlet surfaces can be added to improve the auxiliary heat dissipation efficiency;

[0055] In the second step, if the power unit cabin 42 does not need auxiliary heat dissipation, the staff can reset the servo motor 23 at this time, so that the output shaft of the servo motor 23 drives the worm gear 26 to rotate again and mesh with the worm gear 25. At this time, the first gear 27 will rotate clockwise, so that the first gear 27 will mesh with the first rack 21 on the side wall of the protective plate 18 and the filter plate 19, thereby driving the filter plate 19 and the sliding block 17 to slide toward the side of the travel switch 38 inside the first slide groove 13 and the rectangular groove 16, and the protective plate 18 will extend from the second slide groove 14. Moreover, when the filter plate 19 moves to the end of the first slide groove 13, the filter plate 19 will hit the travel switch 38 inside the first slide groove 13, so that the travel switch 38 will send a signal again to control the servo motor 23 to stop rotating. At the same time, the protective plate 18 will fit with the inner wall of the side box cover 35, thereby achieving a protective effect.

[0056] In the third step, when the filter plate 19 extends from the first slide slot 13 toward the direction of the travel switch 38, the movement of the filter plate 19 will drive the second rack 29 to move, so that the second rack 29 can actively mesh with the second gear 33, so that the second gear 33 generates a radial force to drive the circular shaft 32 to rotate, and then drives the air guide plate 34 to rotate, so that the two sides of the box body 11 can assist in unfolding an air guide plate 34 with an inclined angle. When the inclined air guide plate 37 takes in air, since the inclined air guide plate 37 is square as a whole, part of the wind will flow on both sides of the side box cover 35. By setting up an auxiliary wind shield with an inclined angle on both sides of the box body 11, the air intake efficiency inside the box body 11 can be further improved.

[0057] In the fourth step, after the components inside the power unit cabin 42 are started, the engine radiator 46 starts working immediately. It is mainly composed of an intercooler radiator and a high-pressure fan. When working, the high-pressure fan draws air from the air inlet slot 36, and the air forms an airflow inside the cabin. Then the electronic fan exhausts the air, and the heat is taken out through the circulation of the airflow, thereby realizing the heat dissipation function. At the same time, the temperature control unit inside the PLC controller 39 will monitor the temperature of the cooling medium in the engine radiator 46 in real time, and accurately adjust the speed of the electronic fan according to the received electrical signal. In other words, according to the real-time temperature change of the cooling medium, the fan speed is effectively controlled and adjusted, thereby ensuring that the generator radiator expansion tank 54 can obtain a good heat dissipation effect and ensure the stable operation of the entire system.
