Description

Technical Field

[0001] The present invention belongs to the field of motor equipment, and particularly relates to an ultra-high speed motor with an anti-collision structure and silent heat dissipation for a hydrogen fuel cell. Background Art

[0002] Ultra-high speed motors generally refer to motors with a rotational speed exceeding 10,000 r / min. Because of their high rotational speed and high motor power density, they can effectively save materials. The existing ultra-high speed motors have been widely used, with advantages such as high transmission efficiency, low noise, and fast dynamic response. However, ultra-high speed motors driven by traditional power supply methods are relatively energy-consuming, so using a hydrogen fuel cell as a power supply unit is more conducive to environmental protection.

[0003] The working efficiency of hydrogen fuel cells is very high, but at the same time, due to the flammability of the fuel, their safety risks are also very high. It is very easy to catch fire after being deformed by external impact. When using a hydrogen fuel cell to supply power to an ultra-high speed motor, the heat generated by the battery itself during operation will gradually be transferred to the motor. When the motor works with heat for a long time, its stability is poor, and equipment failures often occur. The noise generated by the motor during operation due to vibration is also a kind of pollution to the environment.

[0004] Therefore, in view of the above situation where the ultra-high speed motor driven by a hydrogen fuel cell has poor impact resistance and high operating noise, a new type of ultra-high speed motor for a hydrogen fuel cell is developed. By using an adjustable double protective cover structure, it can provide anti-impact protection for the hydrogen fuel cell while improving the adsorption ability of the noise generated during the operation of the ultra-high speed motor. Summary of the Invention

[0005] (1) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an ultra-high speed motor with an anti-collision structure and silent heat dissipation for a hydrogen fuel cell. This ultra-high speed motor aims to solve the technical problems that the ultra-high speed motor driven by a hydrogen fuel cell at present has poor battery impact resistance and high motor operating noise.

[0007] (2) Technical Solutions

[0008] To solve the above technical problems, the present invention provides a super-high-speed motor with an anti-collision structure, silent heat dissipation for a hydrogen fuel cell. The super-high-speed motor includes a base platform, a super-high-speed motor body fixedly installed at the upper end of the base platform, and a hydrogen fuel cell body arranged at the rear side of the super-high-speed motor body. A first frame and a second frame are fixedly installed at the upper end of the base platform. The second frame is arranged in front of the first frame. The super-high-speed motor body is installed between the upper ends of the first frame and the second frame. A protective cover adapted to the outer shape of the super-high-speed motor body is arranged at the front end of the hydrogen fuel cell body. The lower sides of the front end of the protective cover are symmetrically connected with support frames. The bottom ends of the support frames are closely attached to the surface of the base platform. The super-high-speed motor body is arranged inside the protective cover. The inner side of the protective cover is covered with sound-absorbing cotton. The protective cover is arranged at the rear side of the second frame. A back plate is fixedly installed at the upper end of the base platform. The back plate is arranged at the rear side of the hydrogen fuel cell body. A heat dissipation unit is installed at the rear end of the back plate. A U-shaped isolation cover is arranged above the hydrogen fuel cell body. A gasket is arranged on the inner wall of the isolation cover. The gasket is closely attached to the outer wall of the hydrogen fuel cell body.

[0009] When using a super-high-speed motor with an anti-collision structure, silent heat dissipation for a hydrogen fuel cell according to this technical solution, the user horizontally inserts the reinforcement frame beam on the hydrogen fuel cell body into the installation slot, and makes the lower surface of the hydrogen fuel cell body slide into place under the rolling action of the pulley. Then, the limit block is horizontally moved along the chute until it reaches both sides of the installation slot, playing a role in horizontally limiting the left and right movement of the reinforcement frame beam. Then, the battery circuit is connected to the super-high-speed motor body. Through the connection of the spring hinge, the protective cover is flipped downward to the horizontal state so that it covers the upper part of the super-high-speed motor body. The sound-absorbing cotton is closely attached to the surface of the super-high-speed motor body. At the same time, by using the rotation of the movable plate on the rotating shaft, the isolation cover is flipped upward to cover the upper part of the hydrogen fuel cell body. The bottom end of the isolation cover falls on the limit block, restricting its further downward flipping. The locking rod is pushed backward along the end seat until it enters the locking hole to fix the front end of the protective cover. The hydrogen fuel cell body supplies power to the super-high-speed motor body to run. The isolation cover and the back plate form a three-sided enclosed protection structure to enhance the anti-impact ability of the hydrogen fuel cell body. The heat dissipation unit accelerates the exchange of hot air around the hydrogen fuel cell body. The noise generated during the operation of the super-high-speed motor body is continuously reflected and reduced on the sound-absorbing cotton and gradually absorbed.

[0010] Preferably, an installation slot is opened at the upper end of the base platform. The installation slot is arranged between the second frame and the back plate. A reinforcement frame beam is installed at the lower end of the hydrogen fuel cell body. The bottom end of the reinforcement frame beam is arranged inside the installation slot. The installation slot makes the hydrogen fuel cell body firmly installed on the base platform through the horizontal limiting effect on the reinforcement frame beam.

[0011] Preferably, two groups of parallel grooves are formed in the upper end of the base platform. The grooves are arranged on both sides of the installation groove, and pulleys are installed inside the grooves. The hydrogen fuel cell body is arranged above the pulleys. The bottom surface of the hydrogen fuel cell body is in close contact with the pulleys. When moving horizontally, the friction is reduced by the rolling of the pulleys, and the installation and disassembly of the hydrogen fuel cell body are more smooth.

[0012] Preferably, rotary shafts are installed at the left and right ends of the first frame. Movable plates with hole slots are fixedly connected to the left and right ends of the isolation cover. The rotary shafts are movably connected to the inner sides of the movable plates. Rotate the movable plate by hand to turn the isolation cover backward from the ultra-high speed motor body onto the hydrogen fuel cell body.

[0013] Preferably, two groups of horizontal frame cross beams are symmetrically connected between the first frame and the second frame. Buffer pads are arranged on the upper ends of the frame cross beams. When the isolation cover is turned forward from the hydrogen fuel cell body onto the ultra-high speed motor body, one end of it touches the buffer pad to prevent it from hitting and being damaged on the frame cross beam.

[0014] Preferably, a spring hinge is movably connected between the front end of the hydrogen fuel cell body and the protective cover. A locking hole is formed in the front end of the protective cover. The protective cover can be manually turned downward to a horizontal state through the spring hinge, or automatically turned upward to a vertical state through the reset action of the spring mechanism.

[0015] Preferably, an end seat is installed on the upper end of the second frame. A locking rod is movably connected inside the end seat. The rear end of the locking rod is arranged inside the locking hole. The locking rod horizontally penetrates through the hole slot in the end seat until it enters the locking hole, locking the front end of the protective cover on the end seat.

[0016] Preferably, sliding grooves are formed at the left and right ends of the base platform. A limiting block with the top flush with the surface of the base platform is horizontally movably connected inside the sliding grooves. The limiting block is arranged below the isolation cover. The limiting block horizontally moves along the sliding groove to one side of the reinforcement frame beam to limit the left and right horizontal movement of the hydrogen fuel cell body. The bottom end of the isolation cover falls on the limiting block to limit its further downward turning.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: A super-high-speed motor with an anti-collision structure and silent heat dissipation for a hydrogen fuel cell of the present invention uses a base platform to provide a stable and solid working platform for the super-high-speed motor body and the hydrogen fuel cell body. By means of a protective cover provided with sound-absorbing cotton that is flipped and covered outside the super-high-speed motor body, the noise generated by the motor is quickly absorbed. The flip-up isolation cover is covered outside the hydrogen fuel cell body to protect its sides and top, avoiding the risk of battery deformation caused by direct impact of foreign objects and resulting in use safety risks. In cooperation with the heat dissipation unit on the back plate, the heat generated on the surface of the hydrogen fuel cell body is quickly dissipated outward, preventing the heat from concentrating on the motor side.

A first frame 2 and a second frame 3 are fixedly installed at the upper end of the base platform 1. The second frame 3 is arranged in front of the first frame 2. The ultra-high speed motor body 4 is installed between the upper ends of the first frame 2 and the second frame 3. A protective cover 6 adapted to the outer shape of the ultra-high speed motor body 4 is arranged at the front end of the hydrogen fuel cell body 5. The lower sides of the left and right of the front end of the protective cover 6 are symmetrically connected with support frames 7. The bottom ends of the support frames 7 are closely attached to the surface of the base platform 1. The ultra-high speed motor body 4 is arranged inside the protective cover 6. The inside of the protective cover 6 is covered with sound-absorbing cotton 8. The protective cover 6 is arranged at the rear side of the second frame 3. A rear backboard 9 is fixedly installed at the upper end of the base platform 1. The rear backboard 9 is arranged at the rear side of the hydrogen fuel cell body 5. A heat dissipation unit 10 is installed at the rear end of the rear backboard 9. A U-shaped isolation cover 11 is arranged above the hydrogen fuel cell body 5. A gasket 12 is arranged on the inner wall of the isolation cover 11. The gasket 12 is closely attached to the outer wall of the hydrogen fuel cell body 5.

[0026] For this specific embodiment, the sound-absorbing cotton 8 is made of artificial inorganic fibers. Using natural ores such as quartz sand, limestone, and dolomite as the main raw materials, and mixing some chemical raw materials such as soda ash and borax to melt into glass. In the molten state, it is blown or spun into flocculent fine fibers by external force. The fibers are three-dimensionally cross-linked and wound around each other, presenting many small gaps. The sound waves emitted by the ultra-high speed motor body 4 are continuously reflected and reduced in the pores of the sound-absorbing cotton 8, achieving the sound insulation effect; the heat dissipation unit 10 includes a refrigerator and an exhaust fan. The exhaust fan extracts the hot air around the hydrogen fuel cell body 5 backward and enters the ventilation duct of the refrigerator, where it exchanges heat with its cooling module to reduce the temperature.

[0027] Among them, an installation groove 13 is formed at the upper end of the base platform 1. The installation groove 13 is arranged between the second frame 3 and the rear back plate 9. A reinforcing frame beam 14 is installed at the lower end of the hydrogen fuel cell body 5. The bottom end of the reinforcing frame beam 14 is arranged inside the installation groove 13. Two groups of parallel grooves 15 are formed at the upper end of the base platform 1. The grooves 15 are arranged on both sides of the installation groove 13. A pulley 16 is installed inside the grooves 15. The hydrogen fuel cell body 5 is arranged above the pulley 16. Chute grooves 25 are formed at the left and right ends of the base platform 1. A limiting block 26 with the top flush with the surface of the base platform 1 is horizontally movably connected inside the chute grooves 25. The limiting block 26 is arranged below the isolation cover 11. Through the horizontal limiting effect on the reinforcing frame beam 14, the installation groove 13 makes the hydrogen fuel cell body 5 firmly installed on the base platform 1. The bottom surface of the hydrogen fuel cell body 5 is closely attached to the pulley 16. When moving horizontally, the rolling of the pulley 16 reduces the frictional force, making the movement, installation, and disassembly of the hydrogen fuel cell body 5 smoother. The limiting block 26 horizontally moves along the chute groove 25 to one side of the reinforcing frame beam 14, restricting the left and right horizontal movement of the hydrogen fuel cell body 5. The bottom end of the isolation cover 11 lands on the limiting block 26, restricting its further downward flipping.

[0028] Meanwhile, rotary shafts 17 are installed at the left and right ends of the first frame 2. Movable plates 18 with hole grooves are fixedly connected to the left and right ends of the isolation cover 11. The rotary shafts 17 are movably connected inside the movable plates 18. Two groups of horizontal frame cross beams 19 are symmetrically connected between the first frame 2 and the second frame 3. A buffer pad 20 is arranged at the upper end of the frame cross beam 19. Rotate the movable plate 18 by hand to make the isolation cover 11 flip backward from the ultra-high speed motor body 4 onto the hydrogen fuel cell body 5. When the isolation cover 11 flips forward from the hydrogen fuel cell body 5 onto the ultra-high speed motor body 4, one end of it touches the buffer pad 20, preventing it from hitting and being damaged on the frame cross beam 19.

[0029] In addition, a spring hinge 21 is movably connected between the front end of the hydrogen fuel cell body 5 and the protective cover 6. A locking hole 22 is formed at the front end of the protective cover 6. An end seat 23 is installed at the upper end of the second frame 3. A locking rod 24 is movably connected inside the end seat 23. The rear end of the locking rod 24 is arranged inside the locking hole 22. The protective cover 6 can be manually flipped downward to a horizontal state through the spring hinge 21, or automatically flipped upward to a vertical state through the reset action of the spring mechanism. The locking rod 24 horizontally penetrates from the hole groove in the end seat 23 until it enters the locking hole 22, locking the front end of the protective cover 6 on the end seat 23.

[0030] When using a super-high-speed motor with an anti-collision structure and silent heat dissipation for a hydrogen fuel cell using this technical solution, the user horizontally inserts the reinforcement frame beam 14 on the hydrogen fuel cell body 5 into the installation groove 13, and makes the lower surface of the hydrogen fuel cell body 5 slide into place under the rolling action of the pulley 16. Then, the limit block 26 is horizontally moved along the chute 25 until it reaches both sides of the installation groove 13, playing a role in limiting the left and right horizontal movement of the reinforcement frame beam 14. Then, the battery circuit is connected to the super-high-speed motor body 4. Through the connection of the spring hinge 21, the protective cover 6 is flipped downward to the horizontal state so that it covers the upper part of the super-high-speed motor body 4, and the sound-absorbing cotton 8 is closely attached to the surface of the super-high-speed motor body 4. At the same time, by using the rotation of the movable plate 18 on the rotating shaft 17, the isolation cover 11 is flipped upward to cover the upper part of the hydrogen fuel cell body 5. The bottom end of the isolation cover 11 lands on the limit block 26, restricting its further downward flipping. The locking rod 24 is pushed backward along the end seat 23 so that it enters the locking hole 22 to fix the front end of the protective cover 6. The hydrogen fuel cell body 5 supplies power for the operation of the super-high-speed motor body 4. The isolation cover 11 and the rear back plate 9 form a three-sided enclosed protection structure to enhance the anti-impact ability of the hydrogen fuel cell body 5. The heat dissipation unit 10 accelerates the exchange of hot air around the hydrogen fuel cell body 5. The noise generated during the operation of the super-high-speed motor body 4 is continuously reflected and reduced on the sound-absorbing cotton 8 and gradually absorbed.
