For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figures 1 to 4 As shown, the present invention provides a crank control device, which includes a crank seat 10, a mounting base 30, a shaft assembly 50, a rocker assembly 20 and a plurality of Hall assemblies 40. The mounting base 30 is embedded and mounted in the crank seat 10, and a movable cavity defining the shaft assembly 50 is formed between the mounting base 30 and the crank seat 10. The crank seat 10 is provided with a mounting cavity 11 and a crank cavity 12 connected to the mounting cavity 11, and the mounting cavity 11 and the crank cavity 12 are in a stepped hole structure, and the aperture of the mounting cavity 11 is larger than the aperture of the crank cavity 12. Preferably, the cross-sectional size of the crank cavity 12 gradually increases from the mounting cavity 11 to the opening direction to form a tapered hole structure, and the rocker assembly 20 can swing at any angle within the range of the tapered hole.

[0031] The shaft assembly 50 includes a columnar transverse shaft 52 and a longitudinal shaft 51. The mounting base 30 is provided with a transverse rotation groove 32 and a longitudinal rotation groove 31 that intersect vertically. The transverse shaft 52 is rotatably limited in the transverse rotation groove 32, and the longitudinal shaft 51 is rotatably limited in the longitudinal rotation groove 31. The mounting base 30 is embedded in the mounting cavity 11, and the cavity wall of the mounting cavity 11 and the mounting base 30 jointly define the transverse shaft 52 and the longitudinal shaft 51.

[0032] The mounting base 30 is located in the mounting cavity 11 to cooperate with the bottom of the mounting cavity 11 to jointly define the shaft assembly 50, and the peripheral wall of the mounting cavity 11 defines the end positions of the transverse shaft 52 and the longitudinal shaft 51, so that the transverse shaft 52 and the longitudinal shaft 51 only have the freedom of rotation, and the other degrees of freedom are restricted by the mounting base 30 and the crank base 10.

[0033] The rocker assembly 20 is connected to the shaft assembly 50 by plugging and assembling, and is integrally mounted on the mounting base 30. The mounting base 30 and the rocker assembly 20 are integrally assembled from the mounting cavity 11 to the crank base 10, and the rocker assembly 20 passes through the crank cavity 12 to achieve assembly connection. The shaft assembly 50 is jointly limited by the mounting base 30 and the crank base 10, so that no additional hole assembly limiting structure is required, and the overall assembly is convenient and the structure is ingenious.

[0034] The rotation centerline of the transverse rotating shaft 52 intersects with the rotation centerline of the longitudinal rotating shaft 51, and the transverse rotating shaft 52 and the longitudinal rotating shaft 51 are in the same plane. The intersection of the transverse rotating shaft 52 and the longitudinal rotating shaft 51 at least partially overlaps and is connected to the rocker assembly 20, so that the rocker assembly 20 can drive at least one of the transverse rotating shaft 52 and the longitudinal rotating shaft 51 to rotate during the swinging process. The transverse rotating shaft 52 and the longitudinal rotating shaft 51 are arranged in a complementary and overlapping manner at the intersection, thereby reducing the overall height. In addition, the overlapping arrangement of the transverse rotating shaft 52 and the longitudinal rotating shaft 51 can also facilitate the control of the rotation stroke and angle.

[0035] The rocker assembly 20 is rotatably connected to the transverse rotating shaft 52 through a pin shaft, and the rocker assembly 20 is inserted into the longitudinal rotating shaft 51 and slidably connected to the driving groove 513 on the longitudinal rotating shaft 51. The rocker assembly 20 passes through the transverse rotating shaft 52 and rotates along the vertical axis direction, which can drive the transverse rotating shaft 52 to rotate around the axis direction. At the same time, the rocker assembly 20 slides in the driving groove 513, thereby preventing the longitudinal rotating shaft 51 from rotating. Alternatively, the rocker assembly 20 passes through the transverse rotating shaft 52 and rotates around the pin axis, that is, the transverse rotating shaft 52 does not rotate. At the same time, the rocker assembly 20 abuts against the lateral rotation of the driving groove 513, thereby driving the longitudinal rotating shaft 51 to rotate around the axis. That is, the rocker assembly 20 can drive the transverse rotating shaft 52 or the longitudinal rotating shaft 51 to rotate alone, and the rocker assembly 20 can also rotate at an angle to drive the transverse rotating shaft 52 and the longitudinal rotating shaft 51 to rotate together, thereby realizing the rotation of the rocker assembly 20 in any direction.

[0036] Multiple groups of Hall components 40 are distributed around the center of the rocker assembly 20 at intervals, so that the Hall components 40 detect the rotation angle of the rocker assembly 20 from multiple directions, thereby outputting corresponding electrical signals based on the change in magnetic field. Among them, the horizontal rotating shaft 52 and the longitudinal rotating shaft 51 are both provided with a mounting groove 511, and each group of Hall components 40 includes a sensing magnet 42 mounted in the mounting groove 511 and a Hall sensing element 41 mounted on the mounting base 30. The rocker assembly 20 drives the horizontal rotating shaft 52 and / or the longitudinal rotating shaft 51 to move, and at least one Hall sensing element 41 outputs an electrical signal based on the change in the magnetic field parameters of the sensing magnet 42.

[0037] The transverse rotating shaft 52 and the longitudinal rotating shaft 51 are both correspondingly installed with Hall components 40, wherein the Hall sensing element 41 is pre-installed with the mounting base 30, and the induction magnet 42 is correspondingly embedded and installed in the transverse rotating shaft 52 and the longitudinal rotating shaft 51. Optionally, the induction magnets 42 are installed at both ends of the transverse rotating shaft 52 and the longitudinal rotating shaft 51, and the Hall component 40 is installed on the mounting base 30, and each Hall component 40 corresponds to the magnetic field output by the induction magnet 42 of the transverse rotating shaft 52 and the longitudinal rotating shaft 51, so that multiple Hall components 40 can sense and output electrical signals together. The control system obtains the rotation direction and rotation value of the rocker assembly 20 based on the electrical signal calculation, thereby controlling the corresponding movement of the moving parts. The Hall sensing element 41 does not require additional wire connection or locking structure, and the overall structure is compact and the assembly alignment is high.

[0038] In one embodiment, the mounting base 30 is inserted into the crank base 10 and snap-connected with the crank base 10. The mounting base 30 snaps into the crank base 10 from the opening of the mounting cavity 11. Optionally, at least two snap-on ribs 33 are provided around the mounting base 30, and the hole wall of the mounting cavity 11 is provided with a snap-on groove. The mounting base 30 is inserted into the mounting cavity 11 until the snap-on ribs 33 snap into the snap-on groove to achieve a snap-on connection, which can achieve a directional positioning connection and avoid separation of the two. At the same time, there is no need to configure an additional locking structure, which greatly improves the convenience of assembly. Preferably, four snap-on ribs 33 are provided, and the four snap-on ribs 33 are evenly distributed on the mounting base 30.

[0039] like Figures 2 to 5 As shown, multiple Hall sensing elements 41 are installed on the mounting base 30 and assembled into the mounting cavity 11 along with the mounting base 30. The horizontal rotating shaft 52 and the longitudinal rotating shaft 51 are set and limited on the mounting base 30, and the Hall sensing elements 41 are fixedly installed on the mounting base 30. Each Hall sensing element 41 corresponds to the induction magnet 42 corresponding to the horizontal rotating shaft 52 and the longitudinal rotating shaft 51, respectively, and the installation consistency is high.

[0040] Further preferably, the mounting base 30 includes a transverse limiting groove 13 and a longitudinal limiting groove which are arc-shaped recessed from the bottom wall of the mounting cavity 11, and the transverse rotation groove 32 and the longitudinal rotation groove 31 are groove structures formed by the arc-shaped recessed from the top wall of the mounting base 30. Among them, the transverse limiting groove 13 and the longitudinal limiting groove intersect in a cross shape, and the transverse rotation groove 32 and the longitudinal rotation groove 31 intersect in a cross shape.

[0041] The transverse limiting groove 13 and the transverse rotation groove 32 are arranged opposite to each other, and the transverse limiting groove 13 and the transverse rotation groove 32 form an activity space for defining the transverse rotation axis 52, so as to jointly define the opposite sides of the transverse rotation axis 52. The longitudinal rotation groove 31 and the longitudinal limiting groove are arranged opposite to each other, and the longitudinal limiting groove and the longitudinal rotation groove 31 form an activity space for defining the longitudinal rotation axis 51, so as to jointly define the opposite sides of the longitudinal rotation axis 51.

[0042] Both the transverse rotating shaft 52 and the longitudinal rotating shaft 51 are limited by the arc groove, and the rotation is not affected, and the rotation flexibility is high. The ends of the transverse rotating shaft 52 and the longitudinal rotating shaft 51 are limited by the side walls of the installation cavity 11 to form an axial limit, so as to keep the range of movement of the transverse rotating shaft 52 and the longitudinal rotating shaft 51 controllable.

[0043] Preferably, the transverse rotating shaft 52 and the longitudinal rotating shaft 51 are arranged to intersect and their rotation axes are in the same plane, and the transverse rotating shaft 52 and the longitudinal rotating shaft 51 are relatively recessed at the intersection to form a mutually matching structure. Among them, the transverse rotating shaft 52 is a cylindrical structure, and its surface is recessed along the circumferential direction to form a groove structure. Specifically, one side of the transverse rotating shaft 52 is radially recessed to form two or more installation grooves 511, and each installation groove 511 can be installed with one or more induction magnets 42, and the induction magnet 42 is a permanent magnet. Further, the other side of the transverse rotating shaft 52 is radially recessed to form a detection groove 512, and the Hall sensing element 41 extends into the detection groove 512 so that the sensing area of ​​the Hall sensing element 41 faces the sensing magnet 42. The detection groove 512 and the mounting groove 511 are both groove structures, which can adjust the matching sensing area of ​​the Hall sensing element 41 and the sensing magnet 42, thereby improving the sensing sensitivity without increasing the installation volume size, and realizing a miniaturized and convenient assembly structure.

[0044] Specifically, the transverse rotating shaft 52 includes a hinged portion 522 and rotating portions 523 located at both ends, and the maximum shaft diameter of the hinged portion 522 is smaller than the maximum shaft diameter of the rotating portion 523. The hinged portion 522 is used to hinge the rocker assembly 20, and the rocker assembly 20 is provided with a rocker column 21, and the rocker column 21 is provided with a transverse swing portion 211 and a longitudinal swing portion 212. Among them, the transverse swing portion 211 and the longitudinal swing portion 212 constitute the chamfered axis structure of the rocker column 21, that is, the transverse swing portion 211 includes two transverse swing planes parallel to each other, and the longitudinal swing portion 212 includes two longitudinal swing planes parallel to each other, and the planes provided by the transverse swing portion 211 and the longitudinal swing portion 212 are perpendicular to each other.

[0045] The hinged portion 522 includes a penetrating swing hole 521 and a hinge hole 524 intersecting the swing hole 521. The rocker assembly 20 passes through the swing hole 521, and the pin passes through the hinge hole 524 to connect the rocker assembly 20. The mounting groove 511 is set on the rotating portion 523. The swing hole 521 is a long hole structure, and its length direction is parallel to the axial direction of the transverse rotating shaft 52. The transverse swing plane and the two side walls of the swing hole 521 are set with a gap to facilitate rotation control. The two ends of the pin are fixedly connected to the hinge hole 524, and the pin passes through the transverse swing part 211 and is rotatably connected to the transverse swing part 211. In a preferred embodiment, the longitudinal swing part 212 is configured as a cylinder to form a sliding fit and can be limited.

[0046] The lateral swinging portion 211 is inserted into the swinging hole 521 of the lateral rotating shaft 52, and the longitudinal swinging portion 212 is inserted into the driving slot 513. The driving slot 513 is configured as a long slot structure, and the length direction of the driving slot 513 is parallel to the axis of the longitudinal rotating shaft 51. The longitudinal swinging plane and the two opposite side surfaces of the driving slot 513 are matched with each other in clearance to form a sliding connection along the length direction of the driving slot 513, and can swing laterally to drive the longitudinal pin to swing. Optionally, the matching clearance is 0.05mm-0.1mm.

[0047] Optionally, the rotating portion 523 is a cylindrical structure to form a rotation adjustment. In another embodiment, the rotating portion 523 is set as a non-cylindrical structure, and the rotating portion 523 includes a semi-axial large diameter portion 5231 and a small diameter portion 5232. The small diameter portion 5232 and the large diameter portion 5231 are coaxially arranged, and the small diameter portion 5232 protrudes from the semi-axial surface of the large diameter portion 5231 to form a semi-axial structure. The outer diameter of the large diameter portion 5231 is greater than the outer diameter of the small diameter portion 5232. The large diameter portion 5231 fits in the transverse rotation groove 32, and the transverse limit groove 13 limits the small diameter portion 5232.

[0048] The large diameter portion 5231 and the small diameter portion 5232 are different sized parts of the rotating portion 523, and the large diameter portion 5231 can limit the maximum rotation angle of the horizontal rotating shaft 52. The mounting groove 511 is recessed and extends from the small diameter portion 5232 to the large diameter portion 5231, and can expand the assembly area of ​​the induction magnet 42, thereby increasing the magnetic field range. In addition, the small diameter portion 5232 is small in size, which can reduce the maximum height of the horizontal rotating shaft 52, thereby shortening the height dimension of the crank control device.

[0049] The rotating portion 523 further includes a detection slot 512, which is recessed and extends from the large diameter portion 5231 toward the small diameter portion 5232, and the Hall sensor element 41 extends into the detection slot 512. The opening direction of the detection slot 512 is opposite to the opening direction of the mounting slot 511, and the Hall sensor element 41 extends into the detection slot 512 to improve the detection accuracy.

[0050] In one embodiment, each rotating portion 523 is provided with two mounting grooves 511, and the detection groove 512 is located between the two mounting grooves 511. Preferably, one of the mounting grooves 511 is provided with an induction magnet 42, and the induction magnet 42 is close to one side of the hinge portion 522. The Hall sensing element 41 detects the induction magnet 42. Preferably, both mounting grooves 511 are provided with induction magnets 42, and the Hall sensing element 41 senses the magnetic fields of the two induction magnets 42, and the magnetic fields between the two adjacent induction magnets 42 are at least partially overlapped, and the Hall sensing element 41 is located in the overlapping magnetic field area to improve the magnetic field sensing effect.

[0051] The structure of the longitudinal rotating shaft 51 is substantially the same as that of the transverse rotating shaft 52, except that the transverse rotating shaft 52 and the longitudinal rotating shaft 51 intersect each other, wherein the longitudinal rotating shaft 51 comprises an arc-shaped curved arm 514 and supporting portions 515 at both ends of the arc-shaped arm 514, and the mounting groove 511 is disposed on the supporting portion 515. The structure of the supporting portion 515 is substantially the same as that of the rotating portion 523, and can be understood by referring to the structure of the rotating portion 523, and will not be described in detail here.

[0052] like Figures 2 to 8 As shown, the difference between the structure of the longitudinal rotating shaft 51 and the structure of the transverse rotating shaft 52 lies in the arc arm 514, wherein the arc arm 514 is a concave arc-shaped curved structure, and the rotation of the transverse rotating shaft 52 is limited to the recess of the arc arm 514, which can not only keep the rotation center of the longitudinal rotating shaft 51 and the rotation center of the transverse rotating shaft 52 coincident, but also reduce the spacing distance between the two.

[0053] The support portion 515 is limited to rotate in the longitudinal rotation slot 31, and the driving slot 513 is set in the arc-shaped arm 514, and the driving slot 513 extends toward the two end support portions 515. The rocker column 21 connects the swing hole 521 of the hinge portion 522 and the driving slot 513 of the arc-shaped arm 514. The interval between the hinge portion 522 and the arc-shaped arm 514 is small, which can make the rocker column 21 more sensitive to control within a small angle.

[0054] Further preferably, the rotation center of the horizontal rotating shaft 52 and the induction center of the corresponding Hall induction element 41 are eccentrically arranged. Preferably, the induction centers of all Hall induction elements 41 are in the same plane, and the magnetic field center formed by the induction magnet 42 installed on the horizontal rotating shaft 52 and the magnetic field center formed by the induction magnet 42 installed on the longitudinal rotating shaft 51 are in the same plane to form a unified magnetic field change. Induction magnets 42 are installed at both ends of the horizontal rotating shaft 52 for comprehensive induction, which can not only improve the accuracy of magnetic field induction, but also avoid the disadvantage of being unable to output signals due to performance changes of a single induction magnet 42.

[0055] In one embodiment, the magnetic field strength of the induction magnet 42 gradually increases from the middle to the two sides, and the magnetic strength of each part of the induction magnet 42 is inconsistent. In this embodiment, the magnetic strength at both ends is greater than the magnetic strength in the middle, so that the magnetic field acting on the Hall sensing element 41 changes during the rotation of the induction magnet 42, and the Hall sensing element 41 outputs a corresponding electrical signal based on the change in magnetic field strength. Among them, the middle magnetic pole strength of the induction magnet 42 is low, and the magnetic pole strength at both ends is high, which can not only output the changing magnetic field strength, but also detect the direction of the magnetic field change. Preferably, there is a difference between the magnetic strength change curve on one side of the symmetry center of the induction magnet 42 and the magnetic strength change curve on the other side of the symmetry center of the induction magnet 42, so that the Hall sensing element 41 determines the direction and angle of the magnetic field change of the induction magnet 42.

[0056] In another embodiment, the magnetic field strength of the induction magnet 42 gradually weakens from the middle to both sides, which is different from the above embodiment in the direction of the gradual change of the magnetic field, wherein the middle magnetic pole strength of the induction magnet 42 is high and the magnetic pole strength at both ends is low, which can output the changing magnetic field strength and detect the direction of the magnetic field change. Preferably, there is a difference between the magnetic strength change curve on one side of the symmetry center of the induction magnet 42 and the magnetic strength change curve on the other side of the symmetry center of the induction magnet 42, so that the Hall induction element 41 determines the direction and angle of the magnetic field change of the induction magnet 42.

[0057] In another embodiment, the magnetic field strength of the induction magnet 42 changes step by step from the middle to both sides in blocks. The difference from the above embodiment is that in this embodiment, the magnetic field strength of the induction magnet 42 changes step by step, and as the induction magnet 42 rotates, the Hall sensor element 41 corresponds to the induction magnetic field strength.

[0058] In a preferred embodiment, two induction magnets 42 with the same magnetic field are respectively installed at the two ends of the horizontal shaft 52, wherein there is an angle difference between the centers of the magnetic poles of the two induction magnets 42. For example, the induction magnets 42 are symmetrically distributed arc magnets, and the magnetic field strength at the two ends of the induction magnets 42 is higher than the magnetic field strength in the middle. The symmetrical mid-sections of the two induction magnets 42 have a deviation angle, and accordingly, the induction centers of the two Hall induction elements 41 correspondingly installed at the two ends of the horizontal device are in the same straight line. When the horizontal device rotates, the two Hall induction elements 41 output the induced voltage correspondingly. Since the two induction magnets 42 have an angle difference, the electrical signal output by the Hall induction element 41 can determine the rotation direction and rotation angle, thereby realizing the response of the angle control signal.
