Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to an ultra-thin coreless torque motor. Background Art

[0002] The ultra-thin coreless torque motor is a specially designed permanent magnet synchronous motor. Its core feature is that it abandons the iron core structure of traditional motors. The stator winding is directly embedded in an epoxy resin or composite material frame, and the rotor uses permanent magnets such as neodymium iron boron or ferrite distributed in a planar ring. Its "ultra-thin" property comes from the compression of the axial dimension, making it suitable for space-constrained scenarios such as robotic joints and precision medical equipment.

[0003] Regarding the above-mentioned related technologies, it is believed that: since the torque motor abandons the iron core structure layout of the traditional motor, the heat conduction path inside the torque motor is interrupted, and the winding temperature rises rapidly. Especially when the winding temperature rises to more than 80 degrees, there is a risk of demagnetization. Summary of the Invention

[0023] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0026] See also Figures 1-13 An embodiment of the present invention provides a technical solution: an ultra-thin coreless torque motor, comprising a base 1, with a circular frame 2 fixedly installed on the left and right sides of the top wall of the base 1, the same shell 4 is installed on the inner walls of the two circular frames 2, a heat dissipation shell 6 is installed on the right side wall of the shell 4, an anti-slip component 8 is installed on the bottom wall of the base 1, a heat dissipation component 5 is installed on the outer wall of the shell 4, and a reinforcement component 3 is installed inside the shell 4.

[0027] Specifically, the heat dissipation assembly 5 includes a stator 52, which is fixedly connected to the inner wall of the outer shell 4. The outer wall of the outer shell 4 is evenly provided with a number of through grooves 51. The outer wall of the stator 52 is evenly provided with a number of heat conduction grooves 55. The inner walls of the several heat conduction grooves 55 are evenly provided with a number of heat dissipation grooves 56. The inner walls of the several heat conduction grooves 55 are fixedly installed with micro heat pipes 57. The outer walls of the several micro heat pipes 57 are all installed with heat dissipation fins 53. The interiors of the several heat dissipation fins 53 are evenly provided with heat guide grooves 54.

[0028] Specifically, a cooling fan 511 is rotatably mounted on the inner wall of the heat dissipation housing 6 via a connecting shaft 510. The left end of the connecting shaft 510 passes through the heat dissipation housing 6 and the outer shell 4 in sequence and is fixedly connected to the reinforcement component 3 via a bearing. An air inlet 1 58 is provided on the right wall of the outer shell 4, and an air inlet 2 59 is provided on the inner wall of the heat dissipation housing 6. By installing the stator 52 inside the shell 4, a heat conduction groove 55 and a heat dissipation groove 56 are opened inside the stator 52. The heat inside the stator 52 can be dissipated to the heat conduction groove 55 through the heat dissipation groove 56, and the micro heat pipe 57 located inside the heat conduction groove 55 absorbs the heat. Then, heat exchange is carried out through the heat dissipation fins 53 installed on the outer wall of the micro heat pipe 57. After the external air flow passes through the heat dissipation fins 53 and the heat guide groove 54, the heat at the end of the heat dissipation fin 53 is taken away and cooled, thereby having the main heat dissipation and cooling function for the entire torque motor, so that the heat conduction path inside the motor is always kept unobstructed. When the strengthening component 3 rotates, it will synchronously drive the connecting shaft 510 and the cooling fan 511 to rotate, so that the external environment cold air flow is sucked into the interior of the shell 4 through the air inlet 1 58 and the air inlet 2 59, accelerating the heat discharge inside the shell 4 and improving the heat dissipation effect of the entire heat dissipation component 5. When the motor is working, the cooling fan 511 rotates to dissipate heat.

[0029] In this embodiment, the provision of the heat dissipation component 5 improves the heat dissipation effect of the entire torque motor, prevents the risk of demagnetization caused by heat accumulation inside the motor, and provides a guarantee for the stable operation of the motor.

[0030] Specifically, the positions of air inlet 1 58 and air inlet 2 59 match and correspond one to one, a positioning frame 512 is fixedly installed on the side wall of the heat dissipation shell 6, and an inner wall of the positioning frame 512 is provided with a through opening that matches air inlet 1 58 and air inlet 2 59.

[0031] In this embodiment, the external cold air flow can pass through the opening on the positioning frame 512, pass through the second air inlet 59 and the first air inlet 58, and then enter the interior of the shell 4 to accelerate the dissipation and discharge of heat.

[0032] Specifically, the front and rear walls of the positioning frame 512 are provided with plug-in slots 513, and the inner wall of the positioning frame 512 is slidably installed with an outer frame 515. The front and rear walls of the outer frame 515 and the positions corresponding to the plug-in slots 513 are provided with magnetic strips 514. The outer walls of the two magnetic strips 514 are adsorbed and fitted with the corresponding inner walls of the plug-in slots 513. A dustproof net 516 is fixedly installed on the inner wall of the outer frame 515. The outer shell 4 is connected to the external environment through air inlet 1 58, air inlet 2 59 and the through port.

[0033] In this embodiment, when the cooling fan 511 is rotating, it guides the external cold air flow into the interior of the shell 4, and then filters the external dust and impurities through the dustproof net 516 to prevent them from entering the interior of the shell 4. When the dustproof net 516 needs to be cleaned, the outer frame 515 is pulled up from the positioning frame 512 to make the magnetic strip 514 separate from the adsorption state with the plug-in slot 513, so that the dustproof net 516 can be taken out for cleaning.

[0034] Specifically, several through grooves 51 are connected to the interior of the shell 4, several through grooves 51 correspond to the positions of corresponding heat conduction grooves 55, several heat dissipation grooves 56 are connected to the interior of the shell 4, the outer walls of several heat dissipation fins 53 are fitted with the inner walls of the heat conduction grooves 55 and the through grooves 51, the outer ends of several heat dissipation fins 53 extend to the outside of the shell 4, and the stator 52 is a honeycomb structure and is filled with thermal conductive glue.

[0035] In this embodiment, the through slot 51 is connected to the interior of the housing 4, which facilitates the installation of the heat dissipation fins 53 in the housing 4 and the stator 52. At the same time, the heat dissipation slot 56 is connected to the interior of the housing 4, so that the heat inside the motor begins to dissipate outward through the heat dissipation slot 56, which has a positioning and guiding effect on the installation and fixation of the heat dissipation fins 53. At the same time, it provides a heat conduction path to keep it unobstructed when the torque motor is working, thereby improving the stable operation of the motor. The thermal conductive glue has the function of conducting heat outward. The heat dissipation fins 53 are installed in the inner wall of the heat conduction groove 55 and the through groove 51. After the micro heat pipe 57 absorbs heat, the heat is dissipated outward through the outer end of the heat dissipation fin 53, so that the heat conduction path inside the motor remains unobstructed, and the overall heat dissipation effect is good, preventing the risk of winding demagnetization caused by high temperature.

[0036] Specifically, the reinforcing component 3 includes a rotating shaft 31 , the rear end of which is rotatably mounted on the side wall of the heat dissipation shell 6 through a bearing seat 32 , and the right end of the rotating shaft 31 is fixedly connected to the left end of the connecting shaft 510 .

[0037] In this embodiment, the rotating shaft 31 serves as an important component of the torque motor, so that the entire motor has the functionality of a driving part. When the rotating shaft 31 rotates, it will synchronously drive the connecting shaft 510 and the cooling fan 511 to rotate and dissipate heat. The rotating shaft 31 uses carbon fiber or epoxy resin laminate as the main raw material. The bending stiffness of the rotating shaft 31 is increased by 3 times, which significantly improves the strength of the rotating shaft 31 and has a good auxiliary effect on improving the overall performance of the motor.

[0038] Specifically, a steering seat 33 is mounted on the outer wall of the rotating shaft 31 , a plurality of rotors 34 are evenly mounted on the outer wall of the steering seat 33 , and a heat-conducting ceramic 35 for dissipating heat of the rotors 34 outward is fixedly mounted on the outer walls of the plurality of rotors 34 .

[0039] In this embodiment, the thermally conductive ceramic 35 has the function of guiding the heat to dissipate outwards, mainly so that the heat inside the motor has a heat conduction path, thereby avoiding high temperature conditions inside the motor.

[0040] Specifically, the anti-slip component 8 includes two rubber pads 83 arranged symmetrically on the left and right sides. Grooves 82 are recessed on the left and right sides of the bottom wall of the base 1. The top walls of the two grooves 82 are fixedly connected to the corresponding top walls of the rubber pads 83. The bottom walls of the two rubber pads 83 are horizontal with the bottom wall of the base 1, and a through groove 81 is provided on the bottom wall of the base 1.

[0041] In this embodiment, by installing a rubber pad 83 in the groove 82 at the bottom of the base 1, the contact between the bottom wall of the base 1 and the mounting surface has good friction, thereby improving the installation stability of the entire motor. The through groove 81 is set to dissipate heat from the bottom of the entire torque motor when it is working.

[0042] Specifically, the front and rear walls of the base 1 are both provided with an embedded groove 84, the top and bottom walls of the two embedded grooves 84 are both provided with a limiting groove 86, the inner walls of the two embedded grooves 84 are both rotatably installed with a bidirectional screw rod 85, and the right ends of the two bidirectional screw rods 85 are both fixedly installed with an adjustment handle through the base 1 through a bearing.

[0043] In this embodiment, the bidirectional screw rod 85 is driven to rotate by rotating the adjustment handle, and the embedded groove 84 is mainly used to install the bidirectional screw rod 85.

[0044] Specifically, cross blocks 87 are screwed on the left and right sides of the outer walls of the two bidirectional screw rods 85, and the outer walls of several cross blocks 87 are slidably connected to the corresponding embedded grooves 84 and the inner walls of the limit grooves 86. The outer walls of several cross blocks 87 are fixedly installed with L-shaped mounting ears 88, and the adjacent sides of several L-shaped mounting ears 88 are slidably connected to the outer wall of the base 1, and the inner walls of several L-shaped mounting ears 88 are installed with fasteners 89.

[0045] In this embodiment, the rotation of the bidirectional screw 85 can drive the cross block 87 to slide along the inner wall of the embedded groove 84 and the limiting groove 86, thereby driving the L-shaped mounting ear 88 and the fastener 89 to move to the appropriate position, making it convenient to install and fix the entire device.

[0046] Specifically, a side housing 7 is installed on the left side wall of the housing 4, and the left end of the rotating shaft 31 passes through the side housing 7 through a bearing and extends to the outside.

[0047] In this embodiment, the side-mounted shell 7 and the heat dissipation shell 6 cooperate with each other to achieve a sealing effect on the left and right sides of the outer shell 4.

[0048] Working Principle: This device optimizes the thermal management of the entire torque motor by providing a strengthening component 3, a heat dissipation component 5, and an anti-slip component 8. By adopting a multi-layer composite heat dissipation component distribution and strengthening its overall structure, the bending stiffness of the shaft 31 is increased by 3 times. The external copper wire of the stator 52 is 3D printed into a honeycomb structure filled with thermal conductive adhesive, which increases the heat transfer to the outside and improves the heat dissipation effect. At the same time, the anti-slip component 8 installed at the bottom of the base 1 improves the stability of the entire torque motor and the mounting table, preventing position shifting during operation. The rotating shaft 31 is rotatably mounted within the stator 52 and the housing 4 via a bearing seat 32. A steering seat 33, a rotor 34, and thermally conductive ceramics 35 are mounted on the exterior of the rotating shaft 31. This improves the material used in the rotating shaft 31, thereby enhancing its strength and overall bending resistance. The provision of the thermally conductive ceramics 35 allows the heat within the entire reinforcement assembly 3 to be dissipated outward during rotation, thereby improving the heat dissipation effect of the entire torque motor. When the rotating shaft 31 rotates, it synchronously drives the connecting shaft 510 and the cooling fan 511 to rotate inside the heat dissipation shell 6, and then the external cold air flow enters the interior of the shell 4 through the dust screen 516, the positioning frame 512, the second air inlet 59 and the first air inlet 58, which can help reduce the temperature inside the shell 4. The cooling fan 511 works as the rotating shaft 31 rotates, so that the operating temperature of the entire torque motor is controlled; When the cooling fan 511 rotates, it guides the external cold air flow into the interior of the housing 4, and then filters the external dust and impurities through the dustproof net 516 to prevent them from entering the interior of the housing 4. When the dustproof net 516 needs to be cleaned, the outer frame 515 is pulled up from the positioning frame 512 to separate the magnetic strip 514 from the adsorption state of the plug-in slot 513, so that the dustproof net 516 can be taken out for cleaning. At the same time, the heat conducting groove 55 provided on the stator 52 allows the micro heat pipe 57 installed in the heat conducting groove 55 to absorb the heat inside the housing 4, and the heat inside the base 1 and the stator 52 can be dissipated outward through the heat dissipation groove 56 and absorbed by the micro heat pipe 57 to be dissipated outward through the heat dissipation fins 53 for cooling. At the same time, the provision of the heat guide groove 54 guides the external air flow to be discharged through the heat guide groove 54, thereby improving the heat dissipation effect of the heat dissipation fins 53. The heat inside the rotor 34 and the stator 52 can be quickly dissipated. The base 1 and the circular frame 2 are mainly provided to support and fix the entire torque motor. At the same time, the setting of the anti-slip component 8 can improve the installation stability of the entire motor. The rubber pad 83 installed in the groove 82 can increase the friction with the installation table, making the contact between the base 1 and the installation table more stable, preventing the motor from shifting during operation. When it is inconvenient to fix the installation position, the corresponding two-way screw rod 85 can be rotated by turning the adjustment handle, and then the cross block 87 can be driven to slide along the outer wall of the two-way screw rod 85 in the embedded groove 84 and the inner wall of the limit groove 86, so that the cross blocks 87 on the left and right sides move away from or close to each other, and simultaneously drive the L-shaped mounting ear 88 and the fastener 89 to move to the appropriate installation position, and the L-shaped mounting ear 88 is screwed and fixed by the fastener 89, thereby completing the installation and fixation of the base 1 and the entire motor.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents.
