Description

Technical Field

[0001] The present application belongs to the field of motor technology, and in particular relates to a high-efficiency energy-saving motor. Background Art

[0002] With the development of science and technology, more and more fields require the use of motors. Motors are devices that convert electrical energy into mechanical energy. They provide driving torque through the rotation of the motor and serve as a power source for various mechanical operations.

[0003] Existing motors convert electrical energy into kinetic energy based on the law of electromagnetic induction to achieve the rotation of the motor shaft. However, the motor will generate a lot of heat during operation. Ordinary motors dissipate heat through the cooling fan rotating with the motor shaft. However, this cooling method has limited effect. The working efficiency of the motor will decrease due to the increase in temperature, and it will consume more electricity. Summary of the invention

[0004] To solve the above problems, the present application provides a high-efficiency energy-saving motor, which adopts a dual cooling method of a cooling fan and a cooling pipe, which can improve the heat dissipation effect of the motor, effectively reduce the temperature of the motor, thereby improving the working efficiency of the motor and saving electricity.

[0005] The present application provides a high-efficiency and energy-saving motor, comprising a body, in which an output shaft is rotatably arranged; a rear end cover, which is arranged on one side of the body, and is provided with a plurality of heat dissipation holes, and an infusion tube is arranged in the rear end cover, and the output shaft is located at one end of the rear end cover and is coaxially connected to a heat dissipation fan; a cooling pipe, which is arranged in the body and has an input end and an output end, and the input end and the output end are both connected to the infusion tube; a piston member, which is arranged in the infusion tube and is used to suck the cooling liquid in the infusion tube from the input end and then output it from the output end; a sliding member, which is slidably arranged on the inner wall of the rear end cover and slides due to wind force, and is in sliding contact with the piston member, and is used to push the piston member to move.

[0006] With such a configuration, when the motor starts to run, the output shaft drives the cooling fan to rotate, and the cooling fan rotates to suck in outside air from the cooling holes and dissipate heat to the machine body. During the rotation of the cooling fan, the sliding member slides on the inner wall of the rear end cover under the action of the wind force of the cooling fan. During the sliding process, the sliding member abuts against the piston member, causing the piston member to start to move, and sucks in the coolant from the input end and discharges it from the output end, so that the coolant circulates in the cooling pipe to reduce the temperature of the coolant while facilitating the coolant to absorb the heat of the machine body to achieve liquid cooling, and the coolant flows in the cooling pipe, which helps to reduce the temperature of the coolant, so that the heat dissipation of the part of the machine body in contact with the coolant is more uniform, and then the machine body dissipates heat through the cooling fan while also dissipating heat through the coolant, thereby improving the heat dissipation effect of the motor, effectively reducing the temperature of the motor, improving the working efficiency of the motor and saving electricity.

[0007] In some embodiments, the sliding member includes: a slider, which is slidably disposed on the inner wall of the rear end cover and slides along the circumferential direction of the output shaft; a stop block, which is disposed on the side wall of the slider and is used to push the piston member to move; and a fan blade, which is disposed on the side of the slider away from the inner wall of the rear end cover, and the fan blade is used to drive the slider to slide on the rear end cover under the wind force of the cooling fan.

[0008] With such arrangement, when the cooling fan rotates, the blades on the slider are acted upon by wind force, and the wind force acts on the slider through the blades, driving the slider to slide along the inner wall of the rear end cover, and then the slider drives the stop block to slide, so as to facilitate the movement of the piston member during the sliding process of the stop block. While utilizing the wind force generated by the rotation of the cooling fan, the piston member can circulate the coolant in the cooling pipe, which helps to speed up the circulation of the coolant.

[0009] In some embodiments, a slideway for the slider to slide is provided on the inner wall of the rear end cover, and balls are provided on both side walls of the slider for rolling. The balls are embedded in the slideway and roll inside the slider.

[0010] With such arrangement, when the blades of the slider are acted upon by wind, the slider slides inside the slide through the ball bearings, thereby enabling the slider to slide on the inner wall of the rear end cover, and furthermore, the ball bearings are used to limit the slider from leaving the slideway, so that after the slider slides along the slideway, the abutment block can abut against the piston member to realize the circulation of the coolant, thereby facilitating the sliding of the slider on the inner wall of the rear end cover.

[0011] In some embodiments, the distance from the section of the slideway close to the piston member to the machine body is greater than the distance from the section of the slideway far from the piston member to the machine body.

[0012] Such arrangement enables the slider to be accelerated by gravity when it slides downward from the slideway, so that when the slider reaches the bottom of the slideway, the stop block also slides and abuts the piston part, and due to the deviation of the slideway, the stop block gradually moves away from the piston part in the process of sliding with the slider, so that the stop block moves away from the piston part after abutting the piston part, so that the piston part can recover after abutting, which helps the stop block to abut the piston part again next time, thereby facilitating the stop block to slide away after abutting the piston part.

[0013] In some embodiments, the motor also includes a locking piece, which is arranged at the top of the body, and the locking piece includes a locking column and a locking spring. The locking column is slidably arranged in the rear end cover, and a release channel connected to the slide is opened on the locking column, and the release channel allows the slider and the block to slide through the locking column together. The locking spring is arranged between the locking column and the rear end cover, and the locking spring elastic force acts on the locking column to stagger the release channel and the slide, and the locking column slides through the top wall of the rear end cover at one end away from the locking spring.

[0014] With such a configuration, when the slider is released from the top of the slideway, the locking column is pressed so that the locking column compresses the locking spring, thereby connecting the release channel with the slideway, so that the slider and the stop block pass through the release channel and slide over the locking column. When the slider is blocked from sliding in the slideway, the locking column is released, and the elastic force of the locking spring acts on the locking column, so that the locking column slides toward the outside of the rear end cover, thereby staggering the release channel with the slideway, so as to block the slider and the stop block from entering the release channel, which helps to stop the slider from sliding on the slideway, so as to facilitate the reset of the slider.

[0015] In some embodiments, the motor also includes a positioning member, which also includes a torsion post, a shift block and a torsion spring. The torsion post is rotatably disposed in the rear end cover and is located on one side of the torsion post. The shift block is connected to the side wall of the torsion post. The shift block is used to abut against the slider. The height of the shift block is higher than the abutment block. The torsion spring acts on the torsion post and drives the shift block to abut the abutment block into the release channel.

[0016] In this way, when the slider is locked at the top of the slideway, the locking spring acts on the locking column, so that the release channel of the locking column is offset from the slideway, and the slider abuts against the side wall of the locking column. At the same time, the torsion force of the torsion spring acts on the slider through the shifting block to press the slider against the side wall of the locking column, thereby locking the slider at the top of the slideway. When the slider is unlocked at the top of the slideway, the locking column is pressed to compress the locking spring and slide toward the inside of the rear end cover, thereby aligning the release channel with the slideway. At the same time, the abutment block also moves into the release channel, thereby limiting the locking column from sliding up under the action of the locking spring, so that the locking column maintains a state of communication between the release channel and the slideway, which helps the slider to slide around the output shaft in the slideway. Moreover, since the torsion force of the torsion spring acts on the torsion column, the resistance block is pressed against the slider, so that the slider has an initial velocity and slides into the release channel, so that the slider has an initial velocity after sliding over the locking column and enters the slideway, which helps the slider to slide in the slideway, and then helps the slider to continuously press the piston to move, so that the coolant circulates in the cooling pipe.

[0017] In some embodiments, one end of the torsion post away from the torsion spring slides through the top wall of the rear end cover.

[0018] With such a configuration, when the slider needs to be locked at the top of the slideway, the torsion post that is exposed from the top wall of the rear end cover is rotated so that the torsion post overcomes the torsion force of the torsion spring and drives the shift block to rotate out of the release channel, and then the locking post is reset under the elastic force of the locking spring, so that the slider can be blocked from continuing to slide by the locking post. Until the slider hits the locking post, the torsion post is released, and the torsion post drives the shift block to abut against the slider under the action of the torsion spring, so that the slider is pressed tightly against the locking post, and then the slider is locked at the top of the slideway.

[0019] In some embodiments, the torsion column and the locking column are arranged on the rear end cover, deviating from the vertical midline of the rear end cover, and the torsion column and the locking column are located in the section of the slideway where the slider slides downward.

[0020] The arrangement is such that in order to lock the slider at the top end of the slideway, after the slider slides to the upper end of the slideway, since the locking post deviates from the mid-vertical line of the rear end cover on the rear end cover, after the slider abuts against the locking post, the slider abuts against the locking block under the action of gravity, even if there is no shift block to press the slider against the locking post. At this time, the slider can abut against the locking post without sliding in the opposite direction, thereby preventing the slider from receiving a reaction force after abutting against the locking post and sliding downward along the slideway in the opposite direction, thereby improving the stability of the locking post in blocking the sliding of the slider.

[0021] In some embodiments, the piston member includes a piston portion, a piston rod and a piston spring. The piston portion is slidably disposed in the infusion tube. One end of the piston rod is connected to the piston portion, and the other end slides through the infusion tube and is used to slide and abut against the abutment block. The piston spring is sleeved on the piston rod located in the infusion tube. The piston spring is used to push the piston rod to drive the piston portion away from the output end. When the piston spring is in a natural state, the input end is located between the piston portion and the output end.

[0022] With such a configuration, when the slider slides circumferentially around the output shaft along the slideway, the slider slides downward along the slideway, so that the slider is affected by gravity and wind force at the same time, which accelerates the speed of the slider sliding downward, so that the slider sliding downward hits the piston rod, so that the piston rod overcomes the elastic force of the piston spring and drives the piston part to compress the liquid in the infusion tube, so that the liquid in the infusion tube enters the cooling pipe through the output end. After the slider slides over the piston rod, the elastic force of the piston spring acts on the piston rod, so that the piston rod drives the piston part to reset, so that the coolant in the cooling pipe enters the infusion pipe through the input end or the output end, so that the liquid in the cooling pipe flows, which helps the coolant in the cooling pipe to exchange heat, and then helps to reduce the temperature of the coolant.

[0023] In some embodiments, a first one-way valve is provided in the input end, and the direction of the first one-way valve is from the input end to the infusion tube. A second one-way valve is provided in the output end, and the direction of the second one-way valve is from the infusion tube to the output end.

[0024] With such a configuration, when the piston rod is impacted and drives the piston part to compress the liquid in the infusion tube, the coolant is input into the cooling pipe from the output end through the second one-way valve. After the slider slides over the piston rod, the piston rod recovers under the elastic force of the piston spring, and the coolant in the cooling pipe enters the infusion tube from the input end through the first one-way valve to replenish the coolant to the infusion tube. As the slider continues to slide and impact the piston rod, the piston rod is continuously compressed and restored under the impact and the piston spring, so that the coolant in the infusion tube only flows out from the output end and flows into the input end, thereby realizing the circulation of the coolant in the cooling pipe, thereby further reducing the temperature of the coolant and facilitating the heat dissipation of the coolant.

[0025] Compared with the prior art, this application has the following advantages:

[0026] While the heat dissipation of the motor is carried out by the rotation of the cooling fan, the coolant inside the body is sucked in from the input end and discharged from the output end, so that the coolant circulates in the cooling pipe to reduce the temperature of the coolant while facilitating the coolant to absorb the heat of the body, thereby realizing liquid cooling and achieving the coexistence of air cooling and water cooling, thereby improving the heat dissipation effect of the motor, effectively reducing the temperature of the motor, improving the working efficiency of the motor and saving electricity.

[0027] Other features and advantages of the present application will be described in the following description, and partly become apparent from the description, or be understood by practicing the present application. The purpose and other advantages of the present application can be realized and obtained by the structures indicated in the description, claims and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] The present application embodiment provides a high-efficiency energy-saving motor, referring to Figures 1 to 3 The motor includes a body 1, a rear end cover 2, a cooling pipe 3, a piston member 4, and a sliding member 5. An output shaft 11 is rotatably arranged in the body 1; the rear end cover 2 is arranged on one side of the body 1. A plurality of heat dissipation holes 21 are arranged on the rear end cover 2. A liquid infusion pipe 22 is arranged in the rear end cover 2. The output shaft 11 is located at one end of the rear end cover 2 and is coaxially connected to a heat dissipation fan 12. The cooling pipe 3 is arranged in the body 1 and has an input end 221 and an output end 222. The input end 221 and the output end 222 are both connected to the liquid infusion pipe 22. The piston member 4 is arranged in the liquid infusion pipe 22, and is used to suck the coolant in the liquid infusion pipe 22 from the input end 221 and then output it from the output end 222. The sliding member 5 is slidably arranged on the inner wall of the rear end cover 2 and slides due to the wind force, and slides against the piston member 4, and is used to push the piston member 4 to move.

[0038] In the embodiment of the present application, the cooling pipe 3 is installed in the body 1, and the piston member 4 is located on the inner wall of the rear end cover 2 and is connected to the cooling pipe 3 through the infusion tube 22, so that the sliding member 5 slides on the rear end cover 2 under the wind force to provide power to the piston member 4, so that the piston member 4 performs piston movement, so that the coolant circulates in the cooling pipe 3 through the infusion tube 22, and the cooling fan 12 cools the motor by air while the coolant circulates to cool the motor by water, thereby improving the heat dissipation effect of the motor, effectively reducing the temperature of the motor, improving the working efficiency of the motor and saving electric energy.

[0039] In some embodiments, reference Figure 3The sliding member 5 includes a slider 51, a stopper 52 and a fan blade 53. The slider 51 is slidably arranged on the inner wall of the rear end cover 2 and slides along the circumferential direction of the heat dissipation fan 12; the stopper 52 is arranged on the side wall of the slider 51 and is used to stop the piston member 4 from moving; the fan blade 53 is arranged on the side of the slider 51 away from the inner wall of the rear end cover 2, and the fan blade 53 is used to be driven by the wind force of the heat dissipation fan 12 to slide on the rear end cover 2.

[0040] Exemplarily, the fan blade 53 is connected to the side of the slider 51 away from the inner wall of the rear end cover 2, and the fan blade 53 is tilted on the slider 51, so that after the fan blade 53 is subjected to the wind force of the heat dissipation fan 12, the fan blade 53 is subjected to the thrust acting on the slider 51, so that the slider 51 slides on the inner wall of the rear end cover 2. The stopper 52 is connected to the side of the slider 51 adjacent to the fan blade 53, and the piston member 4 is located on the path where the stopper 52 slides with the slider 51, so that the stopper 52 pushes the piston member 4 to make the coolant circulate in the cooling pipe 3.

[0041] For example, a slideway 23 for the slider 51 to slide is provided on the inner wall of the rear end cover 2, and balls 511 are provided on both side walls of the slider 51 to roll. In this embodiment, four balls 511 are used. The balls 511 are embedded in the slideway 23 and roll inside the slideway. The slideway 23 is located on the inner wall of the rear end cover 2 and surrounds the inner wall in a circle. A groove for the balls 511 to slide is provided in the slideway 23, so that the balls 511 are restricted from being separated from the slideway 23 after sliding in the slideway 23, thereby facilitating the smooth sliding of the slider 51 and restricting the slider 51 from being separated from the slideway 23.

[0042] For example, refer to Figure 1 and Figure 3 , the distance from the section of the slideway 23 close to the piston member 4 to the body 1 is greater than the distance from the section away from the piston member 4 to the body 1. It can be understood that the annular axis formed by the slideway 23 around the rear end cover 2 forms an angle with the axis center line of the output shaft 11. The section of the slideway 23 close to the piston member 4 is inclined, so that after the stopper 52 pushes against the piston member 4 in the process of sliding with the slider 51, the stopper 52 gradually moves away from the piston member 4 with the slider 51, avoiding the piston member 4 from affecting the sliding of the stopper 52 and the slider 51, and as the slider 51 slides in circles, the stopper 52 continuously pushes against the piston member 4 after sliding with the slider 51.

[0043] In some embodiments, reference Figure 3 and Figure 4The motor further comprises a locking member 6, which is arranged at the top of the body 1. The locking member 6 comprises a locking column 61 and a locking spring 62. The locking column 61 is slidably arranged in the rear end cover 2. A release channel 611 connected to the slideway 23 is provided on the locking column 61. The release channel 611 allows the slider 51 and the stop block 52 to slide through the locking column 61 together. The locking spring 62 is arranged between the locking column 61 and the rear end cover 2. The elastic force of the locking spring 62 acts on the locking column 61 so that the release channel 611 and the slideway 23 are offset, and the end of the locking column 61 away from the locking spring 62 slides through the top wall of the rear end cover 2.

[0044] In this embodiment, the sliding direction of the locking column 61 slides in a direction perpendicular to the rotation axis of the heat dissipation fan 12. The locking column 61 includes a connecting portion 612 located inside the rear end cover 2, a sliding portion 613 slidingly penetrating inside the rear end cover 2, and a button portion 614 connected to one end of the sliding portion 613 away from the connecting portion 612. The release channel 611 is opened on the connecting portion 612, and the extension direction of the release channel 611 is the same as the extension direction of the slide 23. The diameter of the sliding portion 613 is smaller than the button portion 614, so that the locking spring 62 is sleeved on the sliding portion 613. The button portion 614 is located outside the rear end cover 2 and on the top wall of the rear end cover 2. One end of the locking spring 62 is fixed to the outer wall of the rear end cover 2, and the other end of the locking spring 62 is fixed to the button portion 614. The elastic force of the locking spring 62 acts on the button portion 614, so that the release channel 611 on the connecting portion 612 is staggered from the slide 23. When it is necessary to connect the release channel 611 and the slideway 23 , the button portion 614 is pressed to drive the sliding portion 613 to slide toward the rear end cover 2 so that the locking spring 62 is compressed.

[0045] In some embodiments, the motor further includes a positioning member 7. The positioning member 7 further includes a torsion post 71, a shifting block 72 and a torsion spring 73. The torsion post 71 is rotatably disposed in the rear end cover 2 and is located on one side of the torsion post 71. The shifting block 72 is connected to the side wall of the torsion post 71. The shifting block 72 is used to abut against the slider 51, and the height of the shifting block 72 is higher than the abutting block 52. The torsion spring 73 acts on the torsion post 71 and drives the shifting block 72 to abut against the abutting block 52 to enter the release channel 611.

[0046] In this embodiment, the torsion post 71 is rotatably connected in the rear end cover 2, and the extension direction of the rotation axis of the torsion post 71 is the same as the sliding direction of the locking post 61. The torsion spring 73 is sleeved on one end of the torsion post 71 located in the rear end cover 2. The shift block 72 is connected to the peripheral wall of the torsion post 71, and the shift block 72 is located in the rear end cover 2. The torsion force of the torsion spring 73 acts on the torsion post 71, so that the torsion post 71 drives the shift block 72 to rotate toward the release channel 611. The release channel 611 is provided with a positioning groove 615 for the shift block 72 to rotate into. The positioning groove 615 is located on the connecting portion 612, so that the shift block 72 pushes the slider 51 to slide into the release channel 611 under the torsion force of the torsion spring 73, and the slider 51 has an initial velocity after passing through the release channel.

[0047] It should be noted that when the button portion 614 is not pressed, the height of the release channel 611 on the communication portion 612 is higher than the height of the slider 51, so that after the button is pressed, the release channel 611 is connected to the slideway 23, allowing the slider 51 to slide over the locking column 61. After the button portion 614 is pressed, the release channel 611 is connected to the slideway 23, and the shift block 72 pushes the slider 51 to slide into the release channel 611 until the slider 51 slides over the locking column 61, and the shift block 72 rotates into the positioning groove 615 to limit the upward sliding of the communication portion 612, and further limit the upward sliding of the locking column 61, so as to lock the state in which the release channel 611 and the slideway 23 are connected.

[0048] Exemplarily, one end of the torsion post 71 away from the torsion spring 73 slides through the top wall of the rear end cover 2, so that the torsion post 71 can be twisted to drive the shift block 72 to rotate out of the positioning groove 615, and then the locking post 61 is released from the restriction and slides up to reset, so that the connecting portion 612 slides up and blocks the slideway 23, so that the sliding block 51 stops sliding in the slideway 23 after abutting against the locking post 61.

[0049] For example, refer to Figure 2 and Figure 4 The torsion column 71 and the locking column 61 are arranged on the rear end cover 2, deviating from the midline of the vertical direction of the rear end cover 2, and the torsion column 71 and the locking column 61 are located in the section of the slide 23 where the slider 51 slides downward. After the slider 51 slides to the highest point of the slide 23, it continues to slide down before abutting against the locking column 61, so that the slider 51 can also abut against the locking column 61 without sliding in the opposite direction, thereby preventing the slider 51 from receiving a reaction force after abutting against the locking column 61 and sliding downward in the opposite direction along the slide 23, thereby improving the stability of the locking column 61 in blocking the slider 51 from sliding.

[0050] In some embodiments, reference Figure 3 and Figure 5The piston member 4 includes a piston portion 41, a piston rod 42 and a piston spring 43. The piston portion 41 is slidably disposed in the infusion tube 22. One end of the piston rod 42 is connected to the piston portion 41, and the other end slides through the infusion tube 22 and is used to slide against the abutment 52. The piston spring 43 is sleeved on the piston rod 42 located in the infusion tube 22. The piston spring 43 is used to push the piston rod 42 to drive the piston portion 41 away from the output end 222. When the piston spring 43 is in a natural state, the input end 221 is located between the piston portion 41 and the output end 222.

[0051] In the embodiment of the present application, one end of the piston rod 42 is located inside the infusion tube 22, and the other end is located outside the infusion tube 22. The infusion tube 22 is bent and arranged close to the inner wall of the rear end cover 2, and the piston part 41 is connected to the end of the piston rod 42 located inside the infusion tube 22. The piston spring 43 is sleeved on the end of the piston rod 42 located inside the infusion tube 22, and the elastic force of the piston spring 43 acts on the piston part 41, which is used to push the piston part 41 to drive the piston rod 42 to slide on the infusion tube 22, so that the piston part 41 slides inside the infusion tube 22 to compress and expand the liquid in the infusion tube 22. The input end 221 and the output end 222 of the infusion tube 22 are both located at the end of the infusion tube 22 away from the piston rod 42.

[0052] For example, refer to Figure 2 and Figure 5 A first one-way valve is provided in the input end 221 , and the direction of the first one-way valve is from the input end 221 to the infusion tube 22 . A second one-way valve is provided in the output end 222 , and the direction of the second one-way valve is from the infusion tube 22 to the output end 222 .

[0053] Reference Figure 2 , Figure 3 and Figure 5 After the end of the piston rod 42 is hit by the stopper 52, the piston rod 42 drives the piston part 41 to compress the liquid in the liquid infusion tube 22, so that the coolant flows from the output end 222 through the second one-way valve into the cooling pipe 3. The piston spring 43 acts on the piston rod 42, driving the piston part 41 to slide away from the output end 222, so that the coolant flows from the input end 221 through the first one-way valve into the liquid infusion tube 22, and then the coolant circulates in the cooling pipe 3 after passing through the liquid infusion tube 22. This further reduces the temperature of the coolant, which helps the coolant to dissipate heat.

[0054] Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that it is still possible to modify the technical solutions described in the aforementioned embodiments, or to make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
