Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to a motor with a torque control function. Background Art

[0002] An electric motor, commonly known as a motor, is an electromagnetic device that transmits power. In practical applications, the motor needs to cope with various load changes. The load can be divided into constant load and variable load. For variable loads, the motor torque needs to be adjusted accordingly.

[0003] A Chinese invention patent with publication number CN222484471U discloses an air intake grille motor structure with adjustable output torque, comprising: a lower cover, a PCBA assembly, a motor assembly, a steel shaft, an upper cover, and a gear transmission assembly. The gear transmission assembly comprises a driving wheel, a secondary gear, a tertiary gear, a quaternary gear, and an output gear. The quaternary gear comprises two groups with the same structure. The driving wheel, the secondary gear, the tertiary gear, two groups of quaternary gears, and the output gear are meshed in sequence.

[0004] During the torque adjustment process of the above-mentioned output torque adjustable air intake grille motor structure, the upper cover and the lower cover need to be disassembled and installed, and a set of four-stage gears need to be disassembled or installed. The operation is relatively cumbersome and is not conducive to improving the adjustment speed of the motor torque. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a motor with a torque control function.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a motor with a torque control function, comprising a motor body, a mounting box fixed on the top of the motor body, the output end of the motor body passing through the bottom of the mounting box and rotatably connected, a drive box rotatably arranged in the mounting box, a drive tube coaxially arranged with the drive box fixed on the top of the drive box, the drive tube passing through the top of the mounting box and fitting, a drive assembly for transmitting external equipment is provided on the drive tube, and a torque adjustment mechanism is provided on the mounting box for adjusting the output shaft speed of the motor body to change the torque of the drive box.

[0007] By adopting the above technical solution, during the process of torque adjustment of the drive box, the staff only needs to adjust the speed of the output end of the motor body through the torque adjustment mechanism to change the torque of the drive box and the drive tube, eliminating the cumbersome operations of the existing technology and improving the speed of torque adjustment of the device.

[0008] Furthermore, the torque adjustment mechanism includes a first adjustment component, which includes a first main gear fixedly mounted on the output shaft of the motor body, a first driven rod rotatably mounted on the bottom wall of the mounting box and located on the inner side of the drive box, a first driven wheel fixedly mounted on the first driven rod and meshed with the first main gear, and a first ring gear rotatably mounted on the bottom wall of the mounting box and meshed with the first driven wheel, the module of the first main gear, the module of the first driven wheel and the module of the first ring gear are all equal, the number of teeth of the first ring gear is larger than the number of teeth of the first main gear, the number of teeth of the first main gear is larger than the number of teeth of the first driven wheel, the first driven wheel and the first main gear are both located on the inner side of the first ring gear, and the torque adjustment mechanism also includes a second adjustment component for providing another torque to the drive box and a transmission component for driving the drive box to rotate when the first ring gear rotates.

[0009] By adopting the above technical solution, during the rotation of the output shaft of the motor main body, the first main gear fixed to the output shaft of the motor main body, the first driven wheel meshing with the first main gear, the first driven rod connected to the first driven wheel, and the first ring gear meshing with the first driven wheel all rotate, and the first ring gear is driven by the transmission component to rotate, which drives the drive box to rotate. Since the number of teeth of the first ring gear is larger than the number of teeth of the first main gear, the number of teeth of the first main gear is larger than the number of teeth of the first driven wheel, so that the rotation speed of the drive box is lower than the rotation speed of the output shaft of the motor main body, thereby achieving the purpose of increasing the torque of the drive box.

[0010] The cam is secured to the second gear and is engageable with the first gear, and the cam is secured to the second gear by means of a pinion.

[0011] By adopting the above technical solution, during the rotation of the output shaft of the motor main body, the second main gear fixed to the output shaft of the motor main body, the second driven wheel meshing with the second main gear, the second driven rod connected to the second driven wheel, and the second ring gear meshing with the second driven wheel all rotate. Since the module of the first main gear, the module of the second main gear, the module of the second driven wheel and the module of the second ring gear are all equal, the number of teeth of the second main gear is smaller than the number of teeth of the first main gear, the number of teeth of the second driven wheel is larger than the number of teeth of the first driven wheel, and the number of teeth of the second ring gear is equal to the number of teeth of the first ring gear, so that the rotational speeds of the first ring gear and the second ring gear are different. When the second ring gear rotates, the drive box is driven to rotate through the transmission assembly, so that the drive box can obtain another torque output.

[0012] Furthermore, the transmission assembly includes a first transmission ring fixed to the top of the first gear ring, a plurality of first transmission blocks evenly arranged about the axis of the first transmission ring and fixed on the side wall of the first transmission ring, a second transmission ring slidably sleeved on the first transmission ring, a second transmission block fixed on the inner side wall of the second transmission ring, a third transmission ring fixed to the bottom of the second gear ring, and a plurality of third transmission blocks evenly arranged about the axis of the third transmission ring and fixed on the third transmission ring. The second transmission block is plugged in between the two first transmission blocks. The number of the second transmission blocks, the number of the first transmission blocks, and the number of the third transmission blocks are equal and their positions correspond one to one. The torque adjustment mechanism also includes a lifting assembly for driving the drive box to rise and fall.

[0013] By adopting the above technical solution, during the rotation of the first gear ring, the first transmission ring connected to the first transmission ring, the first transmission block connected to the first transmission ring, the second transmission block connected to the first transmission block, the second transmission ring connected to the second transmission block, and the drive box connected to the second transmission ring all rotate, thereby realizing the change of the drive box torque. The driving box is driven to rise by the lifting assembly, so that the second transmission ring connected to the drive box and the second transmission block connected to the second transmission ring all rise. During this process, the second transmission block first rises and separates from the first transmission block, and finally the second transmission block is plugged into the third transmission block. At this time, the rotating second gear ring drives the third transmission ring to rotate, so that the third transmission block connected to the third transmission ring, the second transmission block connected to the third transmission block, and the second transmission ring connected to the second transmission block all rotate, thereby ensuring the normal operation of the other torque output of the drive box.

[0014] Furthermore, the lifting assembly includes an electric push rod fixed to the top of the installation box and an annular rotating plate rotatably installed on the top of the drive box and coaxially arranged with the drive box. The push rod end of the electric push rod passes through the top of the installation box and is slidably connected, and the lower end of the push rod end of the electric push rod is fixed to the top of the annular rotating plate.

[0015] By adopting the above technical solution, the end of the electric push rod is extended or contracted after working, so that the annular rotating plate connected to the end of the electric push rod and the drive box connected to the annular rotating plate are raised and lowered, ensuring the normal torque adjustment of the drive box.

[0016] Furthermore, the drive assembly includes a drive shaft slidably connected to the drive tube, a clip fixed on the inner side wall of the drive tube, and an installation tube fixed on the top of the installation box. The drive shaft passes through the top of the installation tube and fits in. A slot is provided on the side wall of the drive shaft for the clip to pass through and slide into.

[0017] By adopting the above technical solution, the driving tube connected to the driving box rotates during the rotation of the driving box, and the driving shaft rotates under the limiting action of the card strip and the card slot to ensure normal driving operation of the device.

[0018] Furthermore, the drive box and the second transmission ring are jointly provided with an auxiliary component, and a plurality of sliding through holes are penetrated through the bottom of the drive box. The auxiliary component includes an arc slider slidingly set in the sliding through hole, a spring fixed between the arc slider and the inner side wall of the sliding through hole, and an arc slide fixed in the sliding through hole and coaxially arranged with the arc slider. The arc slide passes through the arc slider and slides in conjunction with it. The number of the sliding through holes is equal to the number of groups of auxiliary components and the positions correspond one to one.

[0019] By adopting the above technical solution, the spring setting has a buffering effect when the second transmission block is inserted into the first transmission block or the third transmission block. At the same time, the second transmission block is inserted into the first transmission block or the third transmission block more smoothly.

[0020] Furthermore, a heat dissipation assembly is commonly provided on the mounting box and the mounting tube, and the heat dissipation assembly includes fan blades fixedly mounted on the drive shaft and a first dustproof net that is passed through and fixed on the side wall of the mounting box, a mounting through hole is passed through the top of the mounting tube, and the heat dissipation assembly also includes a second dustproof net fixed in the mounting through hole, and a plurality of ventilation holes are passed through the top of the mounting box.

[0021] By adopting the above technical solution, the drive shaft rotates and drives the fan blades to rotate, and the outside air will enter the installation box through the first dustproof net. The air will then be discharged from the installation box to the installation tube, and finally discharged to the outside through the second dustproof net of the installation through hole. The circulating air can cool the components in the installation box, thereby improving the cooling effect of the device.

[0022] Furthermore, a rotating sleeve is provided on the driving box, a limiting block is fixed on the side wall of the rotating sleeve, a limiting groove is provided on the inner side wall of the installation box, and a limiting rod is fixed between the inner bottom wall and the inner top wall of the installation box, and the limiting rod passes through the limiting block and slides with it.

[0023] By adopting the above technical solution, when the drive box is lifted or lowered, the limit block will be lifted or lowered along the limit rod, thereby improving the stability of the drive box during movement.

[0024] Furthermore, a first inclined surface is provided at the junction of the bottom of the third transmission block and the side walls on both sides of the third transmission block, and the two groups of the first inclined surfaces gradually decrease from top to bottom; a second inclined surface is provided at the junction of the top of the second transmission block and the side walls on both sides of the second transmission block, and the two groups of the second inclined surfaces gradually increase from top to bottom; a third inclined surface is provided at the junction of the bottom of the second transmission block and the side walls on both sides of the second transmission block, and the two groups of the third inclined surfaces gradually decrease from top to bottom; a fourth inclined surface is provided at the junction of the top of the first transmission block and the side walls on both sides of the first transmission block, and the two groups of the fourth inclined surfaces gradually increase from top to bottom.

DETAILED DESCRIPTION

[0029] The technical solutions 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; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] like Figure 1-8 As shown, the embodiment of the present application discloses a motor with a torque control function, including a motor body 1, a torque adjustment mechanism 6, an auxiliary component 8 and a heat dissipation component 9, and a mounting box 2 is fixed on the top of the motor body 1. A plurality of vent holes 95 are provided through the top of the mounting box 2, and the output end of the motor body 1 passes through the bottom of the mounting box 2 and is rotatably connected, and a drive box 3 is rotatably provided inside the mounting box 2. A plurality of sliding through holes 7 are provided through the bottom of the drive box 3, and a drive tube 4 coaxially arranged with the drive box 3 is fixed on the top of the drive box 3, and the drive tube 4 passes through the top of the mounting box 2 and cooperates. In the process of torque adjustment of the drive box 3, the staff only needs to use the torque adjustment mechanism 6 to adjust the rotation speed of the output end of the motor body 1 to change the torque of the drive box 3 and the drive tube 4, eliminating the cumbersome operations of the prior art and improving the speed of torque adjustment of the device.

[0031] The torque adjustment mechanism 6 is mounted on the mounting box 2 and is used to adjust the output shaft speed of the motor body 1 to change the torque of the drive box 3. The torque adjustment mechanism 6 includes a first adjustment assembly 61, a second adjustment assembly 62, a transmission assembly 63, and a lifting assembly 64. The first adjustment assembly 61 includes a first main gear 611, a first driven rod 612, a first driven wheel 613, and a first ring gear 614. The first main gear 611 is fixedly mounted on the output shaft of the motor body 1. The first driven rod 612 is rotatably mounted on the inner bottom wall of the mounting box 2 and is located inside the drive box 3. The first driven wheel 613 is fixedly mounted on the first driven rod 612 and meshes with the first main gear 611. The first ring gear 614 is rotatably mounted on the inner bottom wall of the mounting box 2 and meshes with the first driven wheel 613. The modules of the first master gear 611, the first driven gear 613, and the first ring gear 614 are all equal, and the number of teeth of the first ring gear 614 is greater than that of the first master gear 611. The number of teeth of the first master gear 611 is greater than that of the first driven gear 613, and the first driven gear 613 and the first master gear 611 are both located inside the first ring gear 614. During the rotation of the output shaft of the motor body 1, the first main gear 611 fixed to the output shaft of the motor body 1, the first driven wheel 613 meshing with the first main gear 611, the first driven rod 612 connected to the first driven wheel 613, and the first ring gear 614 meshing with the first driven wheel 613 all rotate, and the first ring gear 614 is driven by the transmission assembly 63 to rotate, thereby driving the drive box 3 to rotate. Since the number of teeth of the first ring gear 614 is larger than that of the first main gear 611, and the number of teeth of the first main gear 611 is larger than that of the first driven wheel 613, the rotation speed of the drive box 3 is lower than the rotation speed of the output shaft of the motor body 1, thereby achieving the purpose of increasing the torque of the drive box 3.

[0032] The second adjustment assembly 62 is used to provide another torque to the drive box 3. The second adjustment assembly 62 includes a second main gear 621, a second driven rod 622, a second driven wheel 623, and a second ring gear 624. The second main gear 621 is fixedly mounted on the output end of the motor body 1. The number of teeth of the second main gear 621 is smaller than the number of teeth of the first main gear 611. The second driven rod 622 is rotatably mounted on the bottom of the mounting box 2 and is located on the inner side of the drive box 3. The second driven wheel 623 is fixedly mounted on the second driven rod 622 and meshes with the second main gear 621. The number of teeth of the second driven wheel 623 is larger than the number of teeth of the first driven wheel 613. The connecting sleeve 625 is rotatably mounted on the top of the first ring gear 614 and is coaxially arranged with the first ring gear 614. The second ring gear 624 is fixed to the top of the connecting sleeve 625 and is coaxially arranged with the connecting sleeve 625. The second ring gear 624 meshes with the second driven gear 623. The number of teeth on the second ring gear 624 is equal to the number of teeth on the first ring gear 614. The modules of the first main gear 611, the second main gear 621, the second driven gear 623, and the second ring gear 624 are all equal. During the rotation of the output shaft of the motor body 1, the second main gear 621 fixed to the output shaft of the motor body 1, the second driven gear 623 meshing with the second main gear 621, the second driven rod 622 connected to the second driven gear 623, and the second ring gear 624 meshing with the second driven gear 623 all rotate. Since the modules of the first main gear 611, the module of the second main gear 621, the module of the second driven gear 623, and the module of the second ring gear 624 are all equal, the number of teeth of the second main gear 621 is smaller than the number of teeth of the first main gear 611, the number of teeth of the second driven gear 623 is larger than the number of teeth of the first driven gear 613, and the number of teeth of the second ring gear 624 is equal to the number of teeth of the first ring gear 614. Therefore, the rotation speeds of the first ring gear 614 and the second ring gear 624 are different. When the second ring gear 624 rotates, the drive box 3 is driven to rotate through the transmission assembly 63, so that the drive box 3 can obtain another torque output.

[0033] The transmission assembly 63 is used to drive the drive box 3 when the second ring gear 624 rotates, and is also used to drive the drive box 3 when the first ring gear 614 rotates. The transmission assembly 63 includes a first transmission ring 631, a first transmission block 632, a second transmission ring 633, a second transmission block 634, a third transmission ring 635, and a third transmission block 636. The first transmission ring 631 is fixed to the top of the first ring gear 614, and the first transmission block 632 is fixed to the side wall of the first transmission ring 631. There are multiple first transmission blocks 632, which are evenly arranged about the axis of the first transmission ring 631. The second transmission block 634 is plugged between two first transmission blocks 632, and the second transmission ring 633 is slidably mounted on the first transmission ring 631. The second transmission block 634 is fixed to the inner side wall of the second transmission ring 633, and the third transmission ring 635 is fixed to the bottom of the second ring gear 624. The third transmission blocks 636 are fixed to the third transmission ring 635. The number of second transmission blocks 634, the number of first transmission blocks 632, and the number of third transmission blocks 636 are equal and their positions correspond one to one. During the rotation of the first ring gear 614, the first transmission ring 631 connected to the first ring gear 614, the first transmission block 632 connected to the first transmission ring 631, the second transmission block 634 connected to the first transmission block 632, the second transmission ring 633 connected to the second transmission block 634, and the drive box 3 connected to the second transmission ring 633 all rotate, thereby changing the torque of the drive box 3. The driving box 3 is driven to rise by the lifting assembly 64, so that the second transmission ring 633 connected to the driving box 3 and the second transmission block 634 connected to the second transmission ring 633 both rise. During this process, the second transmission block 634 first rises and separates from the first transmission block 632, and finally the second transmission block 634 is plugged and connected with the third transmission block 636. At this time, the rotating second gear ring 624 drives the third transmission ring 635 to rotate, so that the third transmission block 636 connected to the third transmission ring 635, the second transmission block 634 connected to the third transmission block 636, and the second transmission ring 633 connected to the second transmission block 634 all rotate, thereby ensuring the normal operation of another torque output of the driving box 3.

[0034] The lifting assembly 64 is used to drive the drive box 3 to rise and fall. The lifting assembly 64 includes an electric push rod 641 and an annular rotating plate 642. The electric push rod 641 is fixed to the top of the installation box 2. The push rod end of the electric push rod 641 passes through the top of the installation box 2 and is slidably connected. The annular rotating plate 642 is rotatably mounted on the top of the drive box 3 and is arranged coaxially with the drive box 3. The lower end of the push rod end of the electric push rod 641 is fixed to the top of the annular rotating plate 642. After the electric push rod 641 is in operation, its push rod end extends or contracts, causing the annular rotating plate 642 connected to the push rod end of the electric push rod 641 and the drive box 3 connected to the annular rotating plate 642 to rise and fall, ensuring normal torque adjustment of the drive box 3.

[0035] The drive assembly 5 is provided on the drive tube 4 and is used to drive the external device. The drive assembly 5 includes a drive shaft 51, a clamping strip 52, and a mounting tube 53. The drive shaft 51 is slidably connected to the drive tube 4 and passes through and fits into the top of the mounting tube 53. A slot 54 is provided on the side wall of the drive shaft 51 for the clamping strip 52 to pass through and slidably fit. The clamping strip 52 is fixed to the inner side wall of the drive tube 4, and the mounting tube 53 is fixed to the top of the mounting box 2. During the rotation of the drive box 3, the drive tube 4 connected to the drive box 3 rotates. Under the limiting action of the clamping strip 52 and the clamping slot 54, the drive shaft 51 rotates to ensure normal driving operation of the device.

[0036] The auxiliary components 8 are jointly arranged on the drive box 3 and the second transmission ring 633. The number of the sliding holes 7 is equal to the number of groups of the auxiliary components 8 and the positions correspond one to one. The auxiliary component 8 includes an arc slider 81, a spring 82 and an arc slide 83. The arc slider 81 is slidably arranged in the sliding hole 7. The spring 82 is fixed between the arc slider 81 and the inner wall of the sliding hole 7. The arc slide 83 is fixed in the sliding hole 7 and is coaxially arranged with the arc slider 81. The arc slide 83 passes through the arc slider 81 and slides in cooperation. The spring 82 is provided to provide a buffering effect when the second transmission block 634 is inserted into the first transmission block 632 or the third transmission block 636. At the same time, the second transmission block 634 is inserted into the first transmission block 632 or the third transmission block 636 more smoothly.

[0037] The heat dissipation assembly 9 is jointly arranged on the mounting box 2 and the mounting cylinder 53. The top of the mounting cylinder 53 is penetrated by a mounting through-hole 94. The heat dissipation assembly 9 includes fan blades 91, a first dustproof net 92, and a second dustproof net 93. The fan blades 91 are fixedly sleeved on the drive shaft 51. The first dustproof net 92 is penetrated and fixed on the side wall of the mounting box 2. The second dustproof net 93 is fixed in the mounting through-hole 94. The drive shaft 51 rotates and drives the fan blades 91 to rotate. The outside air will enter the mounting box 2 through the first dustproof net 92. The air will then be discharged from the mounting box 2 into the mounting cylinder 53, and finally discharged to the outside through the second dustproof net 93 in the mounting through-hole 94. The circulating air can cool the components in the mounting box 2, thereby improving the cooling effect of the device.

A stopper slot 12 is provided on the inner sidewall of the mounting box 2, which slidably engages with the stopper 11. A stopper rod 13 is fixed between the inner bottom and inner top walls of the mounting box 2. The stopper rod 13 extends through the stopper 11 and slidably engages with it. As the drive box 3 is raised or lowered, the stopper 11 rises and falls along the stopper rod 13, improving the stability of the drive box 3 during movement.

[0039] A first inclined surface is provided at the intersection of the bottom of the third transmission block 636 and the side walls on both sides of the third transmission block 636, with the two sets of first inclined surfaces gradually decreasing from top to bottom.
