Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of linear motor, in particular to a self-cooling linear motor. BACKGROUND

[0002] Linear motor is also called linear motor, linear motor, linear motor, push rod motor. The most commonly used linear motor types are flat type, U type slot type and pipe type. The control of linear motor is the same as that of rotary motor, but compared with the two, like one side of the rotary motor, the mover and the stator are not mechanically connected, unlike one side of the rotary motor, the mover rotates and the stator position remains fixed. Linear motor system can be magnetic track movement or thrust coil movement. Therefore, linear motor has found diversified application scenarios in new energy electric vehicle field due to its characteristics of high precision, high speed, high efficiency and low noise, and plays an important role in core power system and key manufacturing link. In the existing patent with patent number CN206259788U, a new linear motor module is disclosed.

[0003] However, the new linear motor module in the above patent in actual operation, such as in the process of various accessories of new energy electric vehicle, since the linear motion speed of the mover on the linear motor is fast, when the linear motor is in long time working state, for example, for the continuous processing and manufacturing of a large number of new energy electric vehicle accessories, a large amount of heat is easy to produce, at this time, if not timely cooling operation, it is easy to affect the working efficiency of the motor itself; in addition, further, in the long time running work, the parts contacted by the mover and the module will also produce large wear, which not only will further produce some heat, affect the heat dissipation of the device, but also will cause large wear of the device, thereby affecting the service life of the device; on the other hand, in the process of back and forth movement of the mover, still due to the too fast running speed of the mover, it is also easy to cause the mover to leave more residual kinetic energy when reaching the end of the stroke, so that the end of the mover is easy to be damaged to a certain extent due to rigid impact, and also produces large degree of noise, at the same time affects the stability of the whole system and the service life of the device. In view of the above problems, the present application file proposes a self-cooling linear motor. SUMMARY

One slide rail is provided on each side of the top of the housing. A mounting seat is slidably connected to each of the two slide rails. A rotor is jointly provided on the two mounting seats. A rack is fixedly connected to each of the two sides of the inner wall of the housing. A rotating shaft is rotatably connected to the mounting seat. A fan blade is provided at the end of the rotating shaft, and a gear is fixedly connected to the rotating shaft, and the gear meshes with the rack; The lubrication mechanism includes push rods. One push rod is slidably connected to each of the two sides of the rotor. One end of the push rod extends into the inner cavity of the rotor. One pressure rod is slidably connected to each of the inner parts of the two sides of the rotor. A through groove is provided inside the pressure rod, and the bottom of the pressure rod extends into the mounting seat.

[0006] Preferably, a slider is fixedly connected to the mounting seat, and the slider is slidably connected to the inside of the slide rail.

[0007] Preferably, the adjacent ends of the push rod and the pressure rod are both arc-shaped, and the through groove inside the pressure rod is in a "U" shape.

[0008] Preferably, a plug is provided on each of the two sides of the top of the rotor, and the plug is cylindrical.

[0009] Preferably, a first spring is wound around the push rod. One end of the first spring is fixedly connected to the push rod, and the other end is fixedly connected to the inside of the rotor. A second spring is wound around the pressure rod. One end of the second spring is fixedly connected to the pressure rod, and the other end is fixedly connected to the inside of the mounting seat.

[0010] Preferably, the buffer mechanism includes a push block, and a push block is connected to the end of the push rod背离 the pressure rod.

[0011] Preferably, a buffer block is slidably connected to each of the two sides of one end of the housing, and an inner groove is provided on the buffer block.

[0012] Preferably, a guide rod is fixedly connected to the buffer block. The guide rod is slidably connected to the inside of the housing, and a third spring is wound around the guide rod. One end of the third spring is fixedly connected to the guide rod, and the other end is fixedly connected to the inside of the housing.

[0013] Preferably, the second heat dissipation mechanism includes an air cushion. An air cushion is provided on the inner wall of one end of the housing. Two L-shaped connecting pipes are connected to the air cushion, and a nozzle body is installed at the end of the connecting pipe.

[0014] Preferably, the mounting base has multiple heat dissipation channels on the side facing the fan blades, and the multiple heat dissipation channels are distributed linearly at equal intervals.

[0015] Compared with the prior art, the present invention provides a self-cooled linear motor, which has the following beneficial effects: 1. This self-cooled linear motor, through the configuration of a mounting base, rack, shaft, gear, fan blades, slide rail, and slider, can be used in actual operation, such as in the processing of some new energy electric vehicle parts. The entire device can be powered on first, and as the mover moves, it will drive the mounting base to move as well. The slider will then move back and forth within the slide rail. The movement of the mounting base will drive the shaft and gear to move together. Since the gear meshes with the rack, it will drive the gear to rotate continuously. The rotation of the gear will then drive the shaft to rotate, which in turn will drive the fan blades to rotate. This facilitates ventilation and heat dissipation of the inner bottom of the mover through the fan blades, ensuring the motor's operating efficiency.

[0016] 2. This self-cooled linear motor, through the configuration of a push rod, a first spring, a pressure rod, a through groove, and a second spring, moves along with the mover, causing the push rod to move as well. When the push rod is compressed and moves, it gradually presses against the pressure rod, while the first spring is simultaneously compressed. This continues until the push rod completely presses against the pressure rod, causing it to move. The second spring is then compressed until the bottom of the through groove inside the pressure rod is exposed between the mounting base and the slide rail. At this point, the lubricant pre-stored in the mover's inner cavity gradually permeates into the space between the mounting base and the slide rail through the through groove inside the pressure rod. This facilitates lubrication between the mover and the module, reducing wear and tear on the device and further minimizing heat generation, thus ensuring the device's service life.

[0017] 3. This self-cooled linear motor, through the setting of a push block, a buffer block, an inner groove, a guide rod, and a third spring, moves the push block along with the push rod during operation. When the push rod moves to the end near the housing, the push block engages with the inner groove on the corresponding buffer block. After the push block enters the inner groove, it gradually applies pressure to the buffer block, causing the guide rod to be displaced under pressure, and the third spring to contract under pressure, until the buffer block completely contacts the inner wall of the housing. In this process, it provides a certain buffering effect at the end of the mover's stroke, reduces noise, and ensures the overall stability of the system and the lifespan of the device.

[0018] 4. This self-cooled linear motor, through the setting of an air cushion, connecting pipe, nozzle body and heat dissipation channel, further enhances the performance in actual operation. As the mover moves, the side away from the push block gradually presses against and squeezes the air cushion near the end of the housing. When the air cushion is compressed, the gas inside it instantly enters the connecting pipe and is then discharged through the corresponding nozzle body. At this time, the gas discharged from the nozzle body blows through the multiple heat dissipation channels set on the inner side of the mounting base, thereby further improving the heat dissipation effect of the entire motor device and ensuring the working efficiency and service life of the device.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] Example 1: Refer to Figures 1-8 A self-cooled linear motor includes a housing 1, a stator 2 installed inside the housing 1, a first heat dissipation mechanism 4 on the housing 1, a mover 3 installed on the first heat dissipation mechanism 4, a lubrication mechanism 5 inside the mover 3, a buffer mechanism 6 jointly provided on the housing 1 and the lubrication mechanism 5, and a second heat dissipation mechanism 7 jointly provided on the housing 1 and the first heat dissipation mechanism 4.

[0024] The first heat dissipation mechanism 4 includes slide rails 406. A slide rail 406 is provided on each of the two sides of the top of the housing 1. A mounting seat 401 is slidably connected to each of the two slide rails 406. A mover 3 is provided on both mounting seats 401. A rack 402 is fixedly connected to each of the two sides of the inner wall of the housing 1. A rotating shaft 403 is rotatably connected to the mounting seat 401. A fan blade 405 is provided at the end of the rotating shaft 403, and a gear 404 is fixedly connected to the rotating shaft 403. The gear 404 meshes with the rack 402. A slider 407 is fixedly connected to the mounting seat 401 and slidably connected inside the slide rails 406. By setting the mounting seats 401, in actual operation, for example in some new... During the processing of components for electric vehicles, the entire device can be connected to the power supply first. As the mover 3 moves, it will drive the mounting base 401 to move as well. The slider 407 will then move back and forth inside the slide rail 406. As the mounting base 401 moves, it will drive the rotating shaft 403 and the gear 404 to move together. Since the gear 404 meshes with the rack 402, it will drive the gear 404 to rotate continuously. Then, the rotation of the gear 404 will drive the rotating shaft 403 to rotate, which in turn will drive the fan blade 405 to rotate. This allows the fan blade 405 to ventilate and dissipate heat on the inner bottom of the mover 3, thus completing the corresponding heat dissipation operation and ensuring the working efficiency of the motor itself.

[0025] The lubrication mechanism 5 includes a push rod 501. One push rod 501 is slidably connected to each side of the mover 3. One end of the push rod 501 extends into the inner cavity of the mover 3. One pressure rod 503 is slidably connected to the inner part of each side of the mover 3. A through groove 504 is provided inside the pressure rod 503, and the bottom of the pressure rod 503 extends into the placement seat 401. The adjacent ends of the push rod 501 and the pressure rod 503 are both arc-shaped. The through groove 504 inside the pressure rod 503 is in a "U" shape. A plug 506 is provided on each side of the top of the mover 3, and the plug 506 is cylindrical. A first spring 502 is wound around the push rod 501. One end of the first spring 502 is fixedly connected to the push rod 501, and the other end is fixedly connected to the inside of the mover 3. A second spring 505 is wound around the pressure rod 503. One end of the second spring 505 is fixedly connected to the pressure rod 503, and the other end is fixedly connected to the inside of the placement seat 401. By providing the push rod 501, during actual operation, as the mover 3 moves, it will also带动 the push rod 501 to move together. Then, when the push rod 501 is pressed and moves, it will gradually抵触 and挤压 the pressure rod 503, and the first spring 502 is simultaneously compressed until the push rod 501 completely挤压 the pressure rod 503, then the pressure rod 503 moves, and the second spring 505 is simultaneously compressed until the bottom of the through groove 504 inside the pressure rod 503 is exposed between the placement seat 401 and the slide rail 406. At this time, the lubricating liquid previously stored in the inner cavity of the mover 3 will pass through the through groove 504 inside the pressure rod 503 and gradually渗透 into the space between the placement seat 401 and the slide rail 406, thus facilitating the corresponding lubrication effect between the mover 3 and the module, reducing the wear degree of the device, and at the same time further reducing the generation of heat, ensuring the service life of the device. After the work is completed, according to the actual situation, the plug 506 can be opened to facilitate补充相应的润滑液 into the inner cavity of the mover 3.

[0026] By providing the placement seat 401, rack 402, rotating shaft 403, gear 404, fan blade 405, slide rail 406, slider 407, push rod 501, first spring 502, pressure rod 503, through groove 504, second spring 505 and plug 506, during actual operation, the entire device can be first connected to the power supply. Then, as the mover 3 moves, it will带动 the placement seat 401 to move together, and the slider 407 will随之来回移动 inside the slide rail 406. As the placement seat 401 moves, it will带动 the rotating shaft 403 and the gear 404 to move together. Since the gear 404 meshes with the rack 402, it will驱动 the gear 404 to continuously rotate. Then, the rotation of the gear 404带动 the rotating shaft 403 to rotate, and进而带动 the fan blade 405 to rotate together, thus facilitating the ventilation and heat dissipation of the inner side of the bottom of the mover 3 through the fan blade 405, so that the corresponding heat dissipation operation can be completed, ensuring the working efficiency of the motor itself.

[0027] Furthermore, in actual operation, as the mover 3 moves, it also drives the push rod 501 to move together. When the push rod 501 is pressed and moves, it gradually presses against the pressure rod 503, while the first spring 502 is compressed at the same time, until the push rod 501 completely presses against the pressure rod 503, causing the pressure rod 503 to move. At the same time, the second spring 505 is compressed, until the bottom of the through groove 504 inside the pressure rod 503 is exposed between the mounting base 401 and the slide rail 406. At this time, the lubricant stored in the inner cavity of the mover 3 will gradually penetrate into the space between the mounting base 401 and the slide rail 406 through the through groove 504 inside the pressure rod 503, thus facilitating the lubrication between the mover 3 and the module, reducing the wear of the device, and further reducing heat generation, ensuring the service life of the device. After the work is completed, the plug 506 can be opened according to the actual situation to facilitate the replenishment of the corresponding lubricant into the inner cavity of the mover 3.

[0028] In this invention, the buffer mechanism 6 includes a push block 601. The end of the push rod 501 facing away from the pressure rod 503 is connected to the push block 601. A buffer block 602 is slidably connected to each side of one end of the housing 1. The buffer block 602 has an inner groove 603, and a guide rod 604 is fixedly connected to it. The guide rod 604 is slidably connected inside the housing 1, and a third spring 605 is wound around it. One end of the third spring 605 is fixedly connected to the guide rod 604, and the other end is fixedly connected to the inside of the housing 1. By configuring the push block 601, buffer block 602, inner groove 603, guide rod 604, and third spring 605, the buffer mechanism 6 can... As the push rod 501 moves during operation, it also drives the push block 601 to move together. When the push rod 501 moves to the end near the housing 1, the push block 601 will engage with the inner groove 603 on the corresponding buffer block 602. After the push block 601 enters the inner groove 603, it will gradually apply pressure to the buffer block 602. The guide rod 604 will be displaced by the pressure, and the third spring 605 will be compressed at the same time until the buffer block 602 completely abuts against the inner wall of the housing 1. In this process, it can play a certain buffering role at the end of the stroke of the mover 3, while reducing the noise level and ensuring the overall stability of the system and the life of the device.

[0029] Example 2: Refer to Figures 1-9 A self-cooled linear motor includes a housing 1, a stator 2 installed inside the housing 1, a first heat dissipation mechanism 4 on the housing 1, a mover 3 installed on the first heat dissipation mechanism 4, a lubrication mechanism 5 inside the mover 3, a buffer mechanism 6 jointly provided on the housing 1 and the lubrication mechanism 5, and a second heat dissipation mechanism 7 jointly provided on the housing 1 and the first heat dissipation mechanism 4.

[0030] The first heat dissipation mechanism 4 includes slide rails 406. A slide rail 406 is provided on each of the two sides of the top of the housing 1. A mounting seat 401 is slidably connected to each of the two slide rails 406. A mover 3 is provided on both mounting seats 401. A rack 402 is fixedly connected to each of the two sides of the inner wall of the housing 1. A rotating shaft 403 is rotatably connected to the mounting seat 401. A fan blade 405 is provided at the end of the rotating shaft 403, and a gear 404 is fixedly connected to the rotating shaft 403. The gear 404 meshes with the rack 402. A slider 407 is fixedly connected to the mounting seat 401 and slidably connected inside the slide rails 406. By setting the mounting seats 401, in actual operation, for example in some new... During the processing of components for electric vehicles, the entire device can be connected to the power supply first. As the mover 3 moves, it will drive the mounting base 401 to move as well. The slider 407 will then move back and forth inside the slide rail 406. As the mounting base 401 moves, it will drive the rotating shaft 403 and the gear 404 to move together. Since the gear 404 meshes with the rack 402, it will drive the gear 404 to rotate continuously. Then, the rotation of the gear 404 will drive the rotating shaft 403 to rotate, which in turn will drive the fan blade 405 to rotate. This allows the fan blade 405 to ventilate and dissipate heat on the inner bottom of the mover 3, thus completing the corresponding heat dissipation operation and ensuring the working efficiency of the motor itself.

[0031] The lubrication mechanism 5 includes a push rod 501. A push rod 501 is slidably connected to each side of the mover 3. One end of the push rod 501 extends into the inner cavity of the mover 3. A pressure rod 503 is slidably connected to the inner part of each side of the mover 3. A through groove 504 is provided inside the pressure rod 503, and the bottom of the pressure rod 503 extends into the placement seat 401. The adjacent ends of the push rod 501 and the pressure rod 503 are both arc-shaped. The through groove 504 inside the pressure rod 503 is in a "U" shape. A plug 506 is provided on each side of the top of the mover 3, and the plug 506 is cylindrical. A first spring 502 is wound around the push rod 501. One end of the first spring 502 is fixedly connected to the push rod 501, and the other end is fixedly connected to the inside of the mover 3. A second spring 505 is wound around the pressure rod 503. One end of the second spring 505 is fixedly connected to the pressure rod 503, and the other end is fixedly connected to the inside of the placement seat 401. By providing the push rod 501, during actual work, as the mover 3 moves, it will also带动 the push rod 501 to move together. Then, when the push rod 501 is pressured and moves, it will gradually抵触 and挤压 the pressure rod 503, and the first spring 502 is simultaneously compressed until the push rod 501 completely挤压 the pressure rod 503, then the pressure rod 503 moves, and the second spring 505 is simultaneously compressed until the bottom of the through groove 504 inside the pressure rod 503 is exposed between the placement seat 401 and the slide rail 406. At this time, the lubricating liquid previously stored in the inner cavity of the mover 3 will pass through the through groove 504 inside the pressure rod 503 and gradually渗透 into the space between the placement seat 401 and the slide rail 406, thus facilitating the corresponding lubrication effect between the mover 3 and the module, reducing the wear degree of the device, and at the same time further reducing the generation of heat and ensuring the service life of the device. After the work is completed, according to the actual situation, the plug 506 can be opened to facilitate replenishing the corresponding lubricating liquid into the inner cavity of the mover 3.

[0032] By providing the placement seat 401, rack 402, rotating shaft 403, gear 404, fan blade 405, slide rail 406, slider 407, push rod 501, first spring 502, pressure rod 503, through groove 504, second spring 505 and plug 506, during actual work, the entire device can be first powered on. Then, as the mover 3 moves, it will带动 the placement seat 401 to move together, and then the slider 407 will move back and forth inside the slide rail 406. As the placement seat 401 moves, it will带动 the rotating shaft 403 and the gear 404 to move together. Since the gear 404 meshes with the rack 402, it will drive the gear 404 to continuously rotate. Then, the rotation of the gear 404带动 the rotation of the rotating shaft 403, and进而带动 the fan blade 405 to rotate together, thus facilitating the ventilation and heat dissipation of the inner side of the bottom of the mover 3 through the fan blade 405, so that the corresponding heat dissipation operation can be completed and the working efficiency of the motor itself can be ensured.

[0033] Furthermore, in actual operation, as the mover 3 moves, it also drives the push rod 501 to move together. When the push rod 501 is pressed and moves, it gradually presses against the pressure rod 503, while the first spring 502 is compressed at the same time, until the push rod 501 completely presses against the pressure rod 503, causing the pressure rod 503 to move. At the same time, the second spring 505 is compressed, until the bottom of the through groove 504 inside the pressure rod 503 is exposed between the mounting base 401 and the slide rail 406. At this time, the lubricant stored in the inner cavity of the mover 3 will gradually penetrate into the space between the mounting base 401 and the slide rail 406 through the through groove 504 inside the pressure rod 503, thus facilitating the lubrication between the mover 3 and the module, reducing the wear of the device, and further reducing heat generation, ensuring the service life of the device. After the work is completed, the plug 506 can be opened according to the actual situation to facilitate the replenishment of the corresponding lubricant into the inner cavity of the mover 3.

[0034] In this invention, the buffer mechanism 6 includes a push block 601. The end of the push rod 501 facing away from the pressure rod 503 is connected to the push block 601. A buffer block 602 is slidably connected to each side of one end of the housing 1. The buffer block 602 has an inner groove 603, and a guide rod 604 is fixedly connected to it. The guide rod 604 is slidably connected inside the housing 1, and a third spring 605 is wound around it. One end of the third spring 605 is fixedly connected to the guide rod 604, and the other end is fixedly connected to the inside of the housing 1. By configuring the push block 601, buffer block 602, inner groove 603, guide rod 604, and third spring 605, the buffer mechanism 6 can... As the push rod 501 moves during operation, it also drives the push block 601 to move together. When the push rod 501 moves to the end near the housing 1, the push block 601 will engage with the inner groove 603 on the corresponding buffer block 602. After the push block 601 enters the inner groove 603, it will gradually apply pressure to the buffer block 602. The guide rod 604 will be displaced by the pressure, and the third spring 605 will be compressed at the same time until the buffer block 602 completely abuts against the inner wall of the housing 1.

[0035] In this invention, the second heat dissipation mechanism 7 includes an air cushion 701. An air cushion 701 is provided on the inner wall of one end of the housing 1. Two L-shaped connecting pipes 702 are connected to the air cushion 701, and a nozzle body 703 is installed at the end of each connecting pipe 702. Multiple heat dissipation channels 704 are provided on the side of the mounting base 401 facing the fan blade 405, and these channels are linearly and equally spaced. By configuring the air cushion 701, connecting pipes 702, nozzle body 703, and heat dissipation channels 704, in actual operation, further, with the movement of the actuator 3... As the movement of the air cushion 701 approaches the end of the housing 1 on the side away from the push block 601, it gradually presses against the air cushion 701. When the air cushion 701 is compressed, the gas inside it will instantly enter the connecting pipe 702 and then be discharged through the corresponding nozzle body 703. At this time, the gas discharged from the nozzle body 703 will blow on the multiple heat dissipation channels 704 set on the inner side of the mounting base 401, thereby further improving the heat dissipation effect of the entire motor device and ensuring the working efficiency and service life of the device.

[0036] Working principle: In use, for example in the processing of some new energy electric vehicle parts, the entire device can be connected to the power supply first. As the mover 3 moves, it will drive the mounting base 401 to move together. The slider 407 will then move back and forth inside the slide rail 406. As the mounting base 401 moves, it will drive the rotating shaft 403 and the gear 404 to move together. Since the gear 404 meshes with the rack 402, it will drive the gear 404 to rotate continuously. Then, the rotation of the gear 404 will drive the rotating shaft 403 to rotate, which in turn will drive the fan blade 405 to rotate together. This facilitates ventilation and heat dissipation of the bottom inner side of the mover 3 through the fan blade 405, so as to complete the corresponding heat dissipation operation and ensure the working efficiency of the motor itself.

[0037] Furthermore, in actual operation, as the mover 3 moves, it also drives the push rod 501 to move together. When the push rod 501 is pressed and moves, it gradually presses against the pressure rod 503, while the first spring 502 is compressed at the same time, until the push rod 501 completely presses against the pressure rod 503, causing the pressure rod 503 to move. At the same time, the second spring 505 is compressed, until the bottom of the through groove 504 inside the pressure rod 503 is exposed between the mounting base 401 and the slide rail 406. At this time, the lubricant stored in the inner cavity of the mover 3 will gradually penetrate into the space between the mounting base 401 and the slide rail 406 through the through groove 504 inside the pressure rod 503, thus facilitating the lubrication between the mover 3 and the module, reducing the wear of the device, and further reducing heat generation, ensuring the service life of the device. After the work is completed, the plug 506 can be opened according to the actual situation to facilitate the replenishment of the corresponding lubricant into the inner cavity of the mover 3.

[0038] Next, as the push rod 501 moves during operation, it will also drive the push block 601 to move together. When the push rod 501 moves to the end near the housing 1, the push block 601 will engage with the inner groove 603 on the corresponding buffer block 602. After the push block 601 enters the inner groove 603, it will gradually apply pressure to the buffer block 602. The guide rod 604 will be displaced by the pressure, and the third spring 605 will be compressed at the same time until the buffer block 602 completely abuts against the inner wall of the housing 1. In this process, it can play a certain buffering role at the end of the stroke of the mover 3, while reducing the noise level and ensuring the overall stability of the system and the life of the device.

[0039] Furthermore, as the mover 3 moves, on the side away from the pusher block 601, it gradually presses against the air cushion 701 as it approaches the end of the housing 1. When the air cushion 701 is compressed, the gas inside it instantly enters the connecting pipe 702 and is then discharged through the corresponding nozzle body 703. At this time, the gas discharged from the nozzle body 703 blows the multiple heat dissipation channels 704 set on the inner side of the mounting base 401, thereby further improving the heat dissipation effect of the entire motor device and ensuring the working efficiency and service life of the device.
