Description

Technical Field

[0001] This invention relates to the field of generator technology, specifically to a power take-off generator device with modular installation. Background Technology

[0002] A power take-off (PTO) generator is a device that converts the kinetic energy of a vehicle into electrical energy. It generates electricity while the vehicle is in motion and features a compact structure, high efficiency, low noise, and long lifespan. It mainly consists of a PTO and a generator, which can be modularly installed for easy inspection and maintenance of the entire device. When assembling the two, the output shaft of the PTO needs to be flanged to the motor shaft of the generator to ensure a firm connection and stable operation. In actual assembly, the modular installation makes the entire installation operation of the PTO generator relatively complicated. It requires not only connecting the PTO and the generator but also fixing them separately, resulting in low installation and disassembly efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a modularly installed power take-off generator device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A modularly installed power take-off generator device includes a generator body, a power take-off unit, and an assembly carrier. The generator body and the power take-off unit are both mounted on the assembly carrier. A motor shaft is provided on the generator body, and an inter-shaft connection assembly is installed on the motor shaft.

[0006] The power take-off unit is provided with an output shaft, and the motor shaft is connected to the output shaft through an inter-shaft connection assembly;

[0007] The assembly carrier is equipped with an upward drive mechanism, which cooperates with the inter-axis connection assembly to drive it to move.

[0008] One end of the upward drive mechanism is connected to a first fixing component, and the other end is connected to a second fixing component. The first fixing component fixes the generator body, and the second fixing component fixes the power take-off.

[0009] The assembly carrier is also equipped with a locking engagement component, which locks the first fixing component and the second fixing component.

[0010] Preferably, a first connecting shaft plate is fixedly disposed on the motor shaft, and a second connecting shaft plate is fixedly disposed on the output shaft.

[0011] Preferably, the inter-shaft connecting assembly is a connecting strip plate, which is mounted on the first connecting shaft plate.

[0012] Preferably, the first connecting shaft plate and the second connecting shaft plate are connected by a connecting strip, and a first toothed ring is fixedly provided on the connecting strip.

[0013] Preferably, the upward driving mechanism includes a supporting rotating shaft and a cooperating bearing block, with the cooperating bearing block installed at each end of the supporting rotating shaft.

[0014] Preferably, a second toothed ring is fixedly provided on the supporting rotating shaft, and the second toothed ring meshes with the first toothed ring to push the first toothed ring to move upward.

[0015] Preferably, a fan blade is also fixedly installed on the supporting shaft. When the first gear ring drives the second gear ring to rotate, the fan blade rotates to assist in the cooling of the generator body.

[0016] Preferably, the mating support block at one end of the supporting shaft is connected to a first fixing component, which is a mating moving strip. The mating support block connected to the mating moving strip drives the mating moving strip to move and achieve the fixed installation of the generator body.

[0017] Preferably, the other end of the supporting shaft is connected to a second fixing component, which includes a connecting moving strip and a body locking strip. The supporting block at this end is connected to the connecting moving strip to drive it to move.

[0018] Preferably, the connecting moving strip is movably connected to the locking strip of the device body to drive its movement, thereby achieving the fixed installation of the power take-off.

[0019] Preferably, the locking assembly is a limiting strip, one end of which engages with the moving strip and the other end of which engages with the connecting moving strip to fix both.

[0020] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages:

[0021] 1. When performing modular installation of the power take-off generator, position the power take-off unit on the assembly base, and then position the generator body so that the motor shaft and the output shaft are aligned. Pushing the support shaft upwards will achieve a fixed connection between the output shaft and the motor shaft, and at the same time complete the fixed installation of the power take-off unit and the generator body. This achieves three goals at once and is simple, convenient and quick to operate.

[0022] 2. When the support shaft moves upward, it will drive the first gear ring and the second gear ring to mesh. At the same time, under the action of the second gear ring, the first gear ring will be pushed upward, so that the first gear ring is coaxial with the motor shaft. At this time, the connecting pin is inserted into the connecting cavity, completing the connection between the output shaft and the motor shaft. Meanwhile, as the support shaft moves upward, it will drive the mating moving strip to move. Under the action of the mating moving strip, the generator body can be fixed.

[0023] 3. In addition, when the support shaft moves upward, it will also drive the connecting moving strip to move. Under the action of the connecting moving strip, the locking strip of the generator body will move to complete the fixation of the power take-off. At the same time, with the movement of the moving strip, the exhaust pipe will be connected to the air box. In this way, when the power take-off generator is working, the first gear ring drives the second gear ring to rotate, and under the action of the fan blades, air will be blown from the air box, which can provide auxiliary heat dissipation from the outside of the generator body.

[0037] This invention provides a technical solution:

[0038] like Figure 1 and Figure 2As shown, a modularly installed power take-off (PTO) generator device includes a generator body 1, a PTO 2, and a mounting base 4.

[0039] like Figure 6 and Figure 7 As shown, a first connecting shaft plate 14 is fixedly installed on the motor shaft 13, a second connecting shaft plate 22 is fixedly installed on the output shaft 21, the shaft connection assembly is a connecting strip plate 3, the connecting strip plate 3 is installed on the first connecting shaft plate 14, the second connecting shaft plate 22 has a connecting cavity 23, the power take-off 2 has symmetrically opened body fixing cavities 24 on both sides, and the power take-off 2 is also fixedly installed with a positioning insert shaft 25.

[0040] The first connecting shaft plate 14 and the second connecting shaft plate 22 are connected by a connecting strip 3. A first toothed ring 34 is fixedly installed on the connecting strip 3. A movable insertion cavity 15 is opened on the first connecting shaft plate 14. In addition, a movable insertion post 31 is fixedly installed on the connecting strip 3. The movable insertion post 31 is inserted into the movable insertion cavity 15. A connecting support plate 32 is fixedly installed at the lower end of the movable insertion post 31. A connecting insertion post 33 is fixedly installed on the connecting support plate 32. When the first connecting shaft plate 14 and the second connecting shaft plate 22 are fixedly connected, the connecting insertion post 33 is inserted into the connecting insertion cavity 23. At this time, the first toothed ring 34 is coaxial with the motor shaft 13. A body support plate 11 is symmetrically fixedly installed at the lower end of the generator body 1. A support base plate 12 is fixedly installed on the body support plate 11.

[0041] like Figure 1 , Figure 2 and Figure 5As shown, a support frame 41 is fixedly installed at one end of the assembly base 4. A limiting protrusion 411 is fixedly installed at one end of the support frame 41, and load-bearing frame rods 42 are symmetrically fixedly installed on both sides of the support frame 41. When the generator body 1 is installed on the assembly base 4, it is placed on the support frame 41, and the end of the body support plate 11 contacts the limiting protrusion 411. An assembly upright plate 43 is fixedly installed at the other end of the assembly base 4. A positioning channel 44 is opened on the assembly upright plate 43, and a support boss 45 is fixedly installed on the assembly upright plate 43. A limiting channel 46 is provided on the upper part, and a moving cavity 47 is symmetrically provided on both sides of the supporting boss 45. When the power take-off 2 is positioned on the assembly plate 43, the positioning insert shaft 25 is inserted into the positioning channel 44. The supporting boss 45 supports the power take-off 2. In addition, a mounting column 48 is symmetrically fixed on the assembly base 4 between the supporting boss 45 and the supporting frame 41. The mounting column 48 is provided with a mating cavity 481, and a mounting rod 49 is symmetrically fixed on both sides of the mounting column 48. A mating block 491 is fixedly provided on the mounting rod 49.

[0042] like Figure 2 , Figure 8 and Figure 9 As shown, the upward drive mechanism includes a support shaft 5 and a mating bearing block 52. The two ends of the support shaft 5 are respectively equipped with mating bearing blocks 52, and the two ends of the support shaft 5 are respectively sleeved with bearings 51. The mating bearing block 52 is provided with mounting holes 53, which are mated with the bearings 51. The lower end of the mating bearing block 52 is fixedly provided with a mating insert rod 54, which is inserted into the mating cavity 481.

[0043] A second toothed ring 55 is fixedly installed on the supporting shaft 5. The second toothed ring 55 meshes with the first toothed ring 34 and pushes the first toothed ring 34 to move upward. A fan blade 56 is also fixedly installed on the supporting shaft 5. When the first toothed ring 34 drives the second toothed ring 55 to rotate, the fan blade 56 rotates to assist in the cooling of the generator body 1. In addition, a limiting shroud 57 is fixedly installed on the cooperating bearing block 52 near one end of the generator body 1. The fan blade 56 is in the limiting shroud 57, and exhaust pipes 58 are symmetrically fixed on both sides of the limiting shroud 57. The limiting shroud 57 restricts the wind force generated by the fan blade 56, so that it is discharged from the exhaust pipes 58.

[0044] like Figure 2 , Figure 3 , Figure 4 and Figure 10As shown, a first fixing component is connected to a mating support block 52 at one end of the supporting shaft 5. The first fixing component is a mating moving strip 6. The mating support block 52 connected to the mating moving strip 6 drives the mating moving strip 6 to move and achieve the fixed installation of the generator body 1. A first assembly connecting rod 59 is hinged on the mating support block 52. A protruding connecting strip 61 is fixedly provided on the mating moving strip 6. The protruding connecting strip 61 is hinged to the lower end of the first assembly connecting rod 59 that is close to it. A first limiting strip hole 62 is opened on the protruding connecting strip 61. Support moving holes are symmetrically opened at both ends of the mating moving strip 6. 63. A support frame rod 42 is inserted into the support moving hole 63, and load-bearing strips 64 are symmetrically fixed at both ends of the moving strip 6. A lower pressure plate 65 and an end baffle 66 are fixedly installed on the load-bearing strip 64, and a support frame 67 is fixedly installed on the load-bearing strip 64. An air outlet box 68 is fixedly installed at the upper end of the support frame 67. A connecting air hole 681 is opened at the end of the air outlet box 68 near the power take-off 2, and a sealing gasket 69 is provided on the end face of the connecting air hole 681. A blowing channel 682 is provided on the end face of the air outlet box 68 facing the generator body 1.

[0045] like Figure 1 , Figure 3 , Figure 4 and Figure 11 As shown, the supporting bearing block 52 at the other end of the supporting shaft 5 is connected to a second fixing component. The second fixing component includes a connecting moving strip 7 and a device locking strip 8. The supporting bearing block 52 at this end is connected to the connecting moving strip 7 to drive it to move. The connecting moving strip 7 is hinged to the lower end of the first assembly connecting rod 59 that is close to it. The connecting moving strip 7 is inserted into the limiting channel 46, and a second limiting strip hole 70 is opened on the connecting moving strip 7. The connecting moving strip 7 is movably connected to the device locking strip 8 to drive it to move, thereby realizing the fixed installation of the power take-off 2. In addition, a lower protruding connecting block 71 is fixedly provided at the lower end of the connecting moving strip 7. The two sides of the lower protruding connecting block 71 are symmetrically hinged to the second assembly connecting rod 72. The other end of the second assembly connecting rod 72 is hinged to the device locking strip 8. The upper end of the device locking strip 8 is fixedly provided with a device locking rod 81, and the lower end is fixedly provided with a locking strip support rod 82. The locking strip support rod 82 is inserted into the moving cavity 47.

[0046] like Figure 2 and Figure 4As shown, the locking assembly is a limiting plate 9. One end of the limiting plate 9 engages with the mating moving strip 6, and the other end engages with the connecting moving strip 7 to fix both. The limiting plate 9 has symmetrically opened movable through holes 91, and a mounting support rod 49 is inserted into the movable through hole 91. A spring 92 is sleeved on the mounting support rod 49. The two ends of the spring 92 are fixed on the limiting plate 9 and the mating block 491 respectively, and the spring 92 is always in a compressed state. The two ends of the limiting plate 9 are symmetrically fixed with limiting posts 93. When the limiting posts 93 do not fix the mating moving strip 6 and the connecting moving strip 7, one end of the limiting post 93 is in contact with the protruding connecting strip 61, and the other end of the limiting post 93 is in contact with the connecting moving strip 7.

[0047] During the modular installation of the power take-off (PTO) generator unit, the PTO 2 is positioned on the assembly carrier 4 and supported by the support boss 45. Simultaneously, the positioning pin 25 is inserted into the positioning channel 44, bringing the PTO 2 into contact with the assembly stand 43. Then, the generator body 1 is placed on the support frame 41, and pushed towards the limiting protrusion 411 until the body support plate 11 contacts the limiting protrusion 411, aligning the motor shaft 13 with the output shaft 21. At this point, the first connecting shaft plate 14 contacts the second connecting shaft plate 22, and the connecting cavity 23 aligns with the connecting post 33. Then, the support shaft 5 is pushed upwards, causing the second gear ring 55 to mesh with the first gear ring 34, simultaneously pushing the first gear ring 34 upwards. This makes it coaxial with the motor shaft 13. At this time, the connecting pin 33 is also inserted into the connecting cavity 23, realizing the fixed connection between the output shaft 21 and the motor shaft 13. When the support shaft 5 moves upward, it will also drive the mating bearing block 52 to move upward. In this way, under the action of the first assembly connecting rod 59, the mating moving strip 6 and the connecting moving strip 7 will move towards each other. As the mating moving strip 6 moves, the lower pressure plate 65 will press on the support base plate 12, and finally the end baffle 66 will contact the end face of the support base plate 12 away from the power take-off 2. In this way, the fixed installation of the generator body 1 can be completed. In addition, in this process, the end of the exhaust pipe 58 will also contact the sealing gasket 69 and squeeze it to deform it. At the same time, the exhaust pipe 58 The upper port is aligned with the connecting air hole 681 to achieve a sealed connection between the exhaust pipe 58 and the air outlet box 68. As the connecting moving bar 7 moves, the second assembly connecting rod 72 will drive the body locking bar 8 to move towards the power take-off 2. With the movement of the body locking bar 8, the body locking rod 81 will be inserted into the body fixing cavity 24 to fix the power take-off 2, thus completing the convenient installation of the power take-off generator device. In addition, with the movement of the connecting moving bar 7 and the cooperating moving bar 6, the limiting post 93 at one end of the limiting bar 9 will be aligned with the first limiting post hole 62, and the limiting post 93 at the other end will be aligned with the second limiting post hole 70. This will cause the limiting bar 9 to lose its restraint, and under the action of the spring 92, the limiting bar 9 will move towards the mounting support post 48. The limiting post 93 is moved so that one end of the limiting post 93 is inserted into the first limiting bar hole 62, and the other end of the limiting post 93 is inserted into the second limiting bar hole 70. Under the action of the limiting post 93, the moving strip 6 and the connecting moving strip 7 are fixed, thus ensuring the firmness and stability of the power take-off generator installation. At this time, the limiting strip 9 is in contact with the mounting support post 48, and the spring 92 is still in a compressed state, ensuring that the limiting post 93 can be stably inserted into the first limiting bar hole 62 and the second limiting bar hole 70. Furthermore, during the operation of the power take-off generator, as the motor shaft 13 rotates, the first gear ring 34 drives the second gear ring 55 to rotate. With the rotation of the second gear ring 55, the supporting shaft 5 rotates, and consequently, the fan blade 56 rotates.The airflow generated by the fan blades 56, under the action of the wind restrictor 57, enters the exhaust pipe 58, then flows into the air outlet box 68, and finally blows through the air blowing channel 682 on the air outlet box 68 towards the generator body 1, thus providing auxiliary cooling for the generator body 1. When it is necessary to disassemble the power take-off generator body 1, simply pull the limiting strip 9 to disengage the limiting post 93 from the first limiting strip hole 62 and the second limiting strip hole 70, respectively.
