[0027] like Figures 1 to 3 As shown, the present invention provides a universal rocker device, which includes a housing assembly 20, a rocker assembly 10, and at least two magnetic field sensing assemblies 30 installed on the housing assembly 20. The rocker assembly 10 includes a spherical magnetic ball 12 and an operating rod 11 connected to the magnetic ball 12, and the magnetic field strength of the magnetic ball 12 is at least partially different in the direction of the center line of the operating rod 11. The operating rod 11 is plugged and installed on the magnetic ball 12, and the center line of the operating rod 11 intersects with the center of the magnetic ball 12.

[0028] The housing assembly 20 is provided with a spherical rotating cavity 22, a rocker cavity 21 connected to the rotating cavity 22, and four sensing cavities 23 spaced around the rotating cavity 22, and the four sensing cavities 23 are connected to the rotating cavity 22. The magnetic ball 12 is confined to the rotating cavity 22 and can rotate in any direction relative to the rotating cavity 22. The magnetic ball 12 itself has a magnetic field change, so as the magnetic ball 12 rotates, the magnetic field angle changes accordingly.

[0029] Each magnetic field sensing component 30 is inserted into the corresponding sensing cavity 23, and the magnetic field sensing component 30 is provided with a sensing element 31, and the detection plane where the center of at least two sensing elements 31 is located coincides with the center of the magnetic ball 12. The operating rod 11 drives the magnetic ball 12 to rotate in any direction, and the magnetic field sensing component 30 outputs a corresponding electrical signal based on the magnetic field change of the magnetic ball 12. The operating rod 11 can drive the magnetic ball 12 to rotate, thereby adjusting the rotation posture of the magnetic ball 12. Preferably, the magnetic ball 12 can rotate around the center of the ball to any angle. Further, the magnetic ball 12 can rotate around the axis of the operating rod 11. Accordingly, in the axial direction of the operating rod 11, the strength of the magnetic ball 12 gradually decreases or increases from the middle to both ends.

[0030] The overall assembly of the rocker assembly 10 is limited to the housing assembly 20, and the magnetic ball 12 can rotate in any direction around the center of the ball, without the need for additional guide and limit structures, and the assembly is convenient and simplified. The universal rocker device has few components, and the installation position of each component on the housing assembly 20 is fixed, and the adjustment and assembly are convenient. The magnetic field sensing assembly 30 is installed at intervals on the housing assembly 20, and can be installed one by one to the sensing cavity 23. The sensing element 31 can be easily adjusted and aligned to the preset sensing position, and the debugging is convenient.

[0031] In one embodiment, the magnetic field sensing component 30 includes a mounting plate 32 embedded in the sensing cavity 23, and the sensing element 31 is disposed on the mounting plate 32, and the sensing element 31 is spaced a preset distance from the magnetic ball 12. The magnetic field sensing component 30 is an inductive sensor made based on the Hall effect, and the sensing element 31 is disposed on one side of the mounting plate 32 and faces the direction of the magnetic ball 12. The mounting plate 32 is embedded and installed in the mounting position of the sensing cavity 23, and is correspondingly connected to the cavity wall of the sensing cavity 23.

[0032] The housing assembly 20 includes a flange seat 24 and a base 25, and the base 25 is fixedly engaged with the flange seat 24 for convenient connection. Both the base 25 and the flange seat 24 are provided with a ball center groove structure, and the base 25 and the flange seat 24 are closed to clamp and limit the magnetic ball 12, which can not only limit the various degrees of freedom of the magnetic ball 12, but also enable the magnetic ball 12 to rotate freely in the rotating cavity 22.

[0033] Preferably, the rocker cavity 21 is arranged on the flange seat 24, and the operating rod 11 passes through the rocker cavity 21 for easy operation. The magnetic field sensing component 30 is installed on the base 25 or the flange seat 24. For example, four magnetic field sensing components 30 are installed on the base 25 and are spaced around the center of the magnetic ball 12, and the flange seat 24 is provided with an air-avoiding space. The base 25 and the flange seat 24 are complementary and embedded in the assembly, and the four magnetic field sensing components 30 are installed in the preset area to achieve convenient assembly.

[0034] Alternatively, four magnetic field sensing components 30 pass through the base 25 and are installed on the flange seat 24. The installation position set by the flange seat 24 can finely adjust the sensing angle of the magnetic field sensing component 30. The base 25 and the flange seat 24 are complementary and embedded for assembly. The base 25 performs secondary limitation on the mounting plate 32 to keep the position of the mounting plate 32 fixed. The assembly positioning and the secondary fixing positioning are separated, thereby improving the detection position accuracy of the magnetic field sensing component 30.

[0035] like Figures 2 to 5 As shown, in one embodiment, the flange seat 24 includes a mounting surface 242, a spherically recessed rotation groove and a plurality of vertically recessed sensing grooves 233. The flange seat 24 serves as the mounting position of the universal rocker device and the rack platform. The flange seat 24 is provided with a mounting surface 242, which is used to fit and press the plane of the rack platform.

[0036] The rotation groove and the induction groove 233 are both configured as groove structures. Optionally, the rotation groove and the induction groove 233 are formed by being recessed from different parts of the flange seat 24. Preferably, the rotation groove and the induction groove 233 are both formed by being recessed from the mounting surface 242 to form the same assembly plane. The base 25 is mounted on the mounting surface 242, wherein the base 25 is provided with a concave ball groove 251 matching the rotation groove, and the concave ball groove 251 and the rotation groove are combined to form the rotation chamber 22.

[0037] The sensing groove 233 is set as an irregular concave structure, wherein the sensing groove 233 includes an installation area 231 and a sensing area 232, and the width dimension of the installation area 231 is greater than the width dimension of the sensing area 232. The installation area 231 and the sensing area 232 constitute a concave space structure approximately in a T shape, and the sensing area 232 intersects with the rotating groove, so that the sensing groove 233 and the rotating cavity 22 are connected. The magnetic field sensing component 30 is limited to the installation area 231, and the sensing element 31 protrudes along the sensing area 232 toward the rotating groove, so as to facilitate the adjustment of the spacing distance between the sensing element 31 and the magnetic ball 12, so as to further reduce the lower area of ​​the base 25 and the universal rocker device on the basis of maintaining the small sensing sensitivity error of the sensing element 31, thereby reducing the overall size and realizing small-size installation.

[0038] In a preferred embodiment, the flange seat 24 also includes a calibration groove 248 recessed from the mounting surface 242, the calibration groove 248 is located between two adjacent sensing grooves 233, a calibration block is installed in the calibration groove 248, and the magnetic ball 12 is connected to the calibration block by magnetic induction to calibrate the initial position. The calibration groove 248 is located at the symmetrical center of the two sensing grooves 233, so as to realize the directional calibration of the initial position of the magnetic ball 12. Preferably, the four sensing grooves 233 are distributed in a square fixed position, and the calibration groove 248 is located at a forty-five degree angle between the two sensing grooves 233. The calibration block is made of ferromagnetic material, such as an iron block or a steel block.

[0039] In one embodiment, the magnetic ball 12 includes a magnetic body 13 and an external sphere 14 wrapped around the magnetic body 13, the magnetic body 13 is provided with a positioning notch 132, and the operating rod 11 passes through the external sphere 14 and is plugged and connected with the magnetic body 13. The magnetic body 13 is provided with a positioning notch 132. When the positioning notch 132 faces or faces away from the calibration block, the magnetic field sensing component 30 outputs a calibration signal accordingly. The external sphere 14 can be coated with an alloy material, which can not only improve the wear resistance, but also maintain the stability of the magnetic field of the magnetic body 13. For example, the external sphere 14 is made of zinc alloy material.

[0040] Preferably, the external sphere 14 is formed on the magnetic body 13, and the two are tightly combined. The magnetic body 13 can be magnetized in sections to form different magnetic field distribution effects.

[0041] Preferably, there are lubricating lines between the external sphere 14 and the cavity wall of the rotating cavity 22, and the lubricating lines can store lubricating grease, which can not only improve the flexibility of rotation, but also keep the rotation tight. Optionally, the lubricating lines are distributed on the surface of the external sphere 14, and optionally, the lubricating lines are wavy lines, annular lines, grid lines, and dot lines that are distributed at intervals or crosswise. The lubricating lines are micron-level, have little effect on the size, and can store and maintain the lubrication of the surface of the external sphere 14.

[0042] In one embodiment, the magnetic body 13 is located inside the magnetic ball 12, wherein the magnetic body 13 is curved, that is, the magnetic body 13 is approximately C-shaped. The positioning notch 132 is formed by both ends of the magnetic body 13 to form a positioning structure. A hole structure is formed in the center of the magnetic body 13, and the operating rod 11 is inserted into the hole in the center of the external sphere 14 and the magnetic body 13.

[0043] In order to further improve the matching accuracy of the operating rod 11 and the magnetic body 13, the inner wall of the magnetic body 13 is provided with at least one positioning surface 131, and the operating rod 11 is provided with a matching surface 111, and the matching surface 111 and the positioning surface 131 are at least partially in contact. The operating rod 11 adopts a chamfered shaft, and the matching surface 111 and the positioning surface 131 are matched and positioned to maintain high assembly accuracy of the operating rod 11 and the magnetic body 13.

[0044] In another embodiment, the magnetic ball 12 includes an upper hemisphere and a lower hemisphere that are assembled together to form a spherical shape, and the strength of the magnetic ball 12 gradually decreases or increases from the middle to the two ends. The magnetic fields of the upper hemisphere and the lower hemisphere gradually change, so that a changing magnetic field can be formed, wherein the operating rod 11 passes through the upper hemisphere and the lower hemisphere, and the center of the operating rod 11 coincides with the center line of the upper hemisphere and the lower hemisphere. During the rotation of the magnetic ball 12, the magnetic lines of force of the magnetic ball 12 pass through the sensing element 31 to form a sensing signal, thereby realizing detection and sensing.

[0045] Optionally, the upper hemisphere and the lower hemisphere are symmetrical structures, and the magnetic field strength of the upper hemisphere gradually increases from the hemisphere surface to the end surface. The closed surface of the upper hemisphere and the lower hemisphere constitutes the area with the maximum magnetic field strength. When the magnetic ball 12 rotates a corresponding angle, the closed surface is inclined relative to the sensing element 31. Accordingly, the magnetic field changes detected by the sensing element 31 to output a corresponding electrical signal.

[0046] Optionally, the upper hemisphere and the lower hemisphere are symmetrical structures, and the magnetic field strength of the upper hemisphere gradually decreases from the hemisphere surface to the end surface. The closed surface of the upper hemisphere and the lower hemisphere constitutes the area with the minimum magnetic field strength. When the magnetic ball 12 rotates a corresponding angle, the closed surface is inclined relative to the sensing element 31. Accordingly, the magnetic field changes detected by the sensing element 31 to output a corresponding electrical signal.

[0047] like Figures 2 to 5 As shown, in one embodiment, the flange seat 24 is provided with a flange seat 24 including a concentrically arranged spacer groove 243 and a sealing groove 244, and the sealing groove 244 is used to install a sealing ring. Among them, the flange seat 24 is provided with a laterally protruding flange flange 241, and the sealing ring is located on the flange flange 241. When the flange seat 24 is installed on the rack platform, the sealing ring is sealed and connected to the rack. A flange hole is provided on the flange flange 241 for locking the flange seat 24.

[0048] One side of the flange seat 24 is used to install the base 25, and the other side of the flange seat 24 protrudes to form an annular boss 245. The annular boss 245 is used to install a protective cover or other accessories to keep the active part of the rocker assembly 10 hidden and neat.

[0049] The annular boss 245 is a protruding annular structure. Furthermore, the spacing groove 243 extends to the annular boss 245, and the flange seat 24 forms an elastic deformation area at the annular boss 245 corresponding to the spacing groove 243. The depth of the spacing groove 243 exceeds the thickness of the flange flange 241 and extends into the annular boss 245. Accordingly, the spacing groove 243 separates the flange seat 24 into a central area 247 and a flange area 246. The central area 247 and the flange area 246 form an appropriate elastic deformation effect at the annular boss 245. That is, the local bending and appropriate deformation formed by the external force or impact on the central area 247 will not affect the connection and fixation of the flange area 246, and has a more excellent buffering effect and operation stability.

[0050] Furthermore, the flange seat 24 is provided with at least two positioning bosses 249, which are located in the surrounding area of ​​the spacer groove 243, and the base 25 is fitted with the positioning bosses 249. The base 25 is fitted with the end of the central area 247, and the base 25 is configured as a columnar or tubular structure. The base 25 is connected to the central area 247 and is complementary and fitted with a plurality of positioning bosses 249, which is not only tightly combined, but also has a small installation space for the base 25. The universal rocker device can be inserted into the installation hole of the rack platform, which improves the convenience of installation and the controllability of the hole size.

[0051] Further preferably, an anti-fool mechanism 26 is provided between the mating surfaces 111 of the base 25 and the flange seat 24, and the anti-fool mechanism 26 can guide the base 25 and the flange seat 24 to be assembled in a directional manner. Optionally, the anti-fool mechanism 26 includes an anti-fool convex column provided on the base 25 and an anti-fool groove provided on the flange seat 24. During the fitting process of the base 25 and the flange seat 24, the anti-fool convex column is inserted into the anti-fool groove to form a directional assembly, and the assembly effect is good. Of course, the anti-fool mechanism 26 can also adopt other anti-fool structures to form a directional assembly. Further, the base 25 and the flange seat 24 are locked and connected by at least two fasteners.

[0052] The operating rod 11 drives the magnetic ball 12 to rotate, wherein the operating rod 11 is at least partially located in the rocker cavity 21, and the rocker cavity 21 limits the maximum range of motion of the operating rod 11, thereby achieving maximum angle control. For example, the rocker cavity 21 can be set as a conical hole, a rectangular hole, a polygonal hole, or a hole of a symmetrical structure, and the cavity wall of the rocker cavity 21 can be set as a conical surface, a vertical surface, or an inclined surface with different curvatures.

[0053] In one embodiment, the rocker cavity 21 includes an oblique cavity wall that gradually increases from the rotation cavity 22, and the oblique cavity wall includes a limit angle 211 and a sliding surface 212. The limit angles 211 are distributed at four corners, and the sliding surface 212 protrudes toward the center direction of the rocker cavity 21 and is smoothly connected with two adjacent limit angles 211. The oblique cavity wall is a curved hole structure formed by the continuous intersection of the wall surfaces of the four limit angles 211 and the four sliding surfaces 212. The limit angles 211 are located at the four corners and are concave relative to the sliding surface 212, so that the operating rod 11 rotates to the limit angle 211 to form a limit rotation. Preferably, the limit angle 211 is located in the middle area between two adjacent magnetic field sensing components 30, and each magnetic field sensing component 30 corresponds to the middle position of the sliding surface 212. Preferably, the sliding surface 212 is set as a convex curved surface to guide the operating rod 11 to slide around the box.

[0054] The sliding surface 212 is set as an arc structure, and the operating rod 11 can slide to both sides to form forward and oblique sliding in multiple directions, so as to flexibly adjust the rotation position of the operating rod 11. Further preferably, the base 25 is provided with a protruding protective rib, and the protective rib is provided with a protective wall 252, and the protective wall 252 is provided with an inclined wall surface. The wall shape of the protective rib is basically the same as the shape of the oblique cavity wall, and the end of the operating rod 11 passes through the magnetic ball 12 and is limited by the protective rib, so that the operating rod 11 is limited at both ends of the magnetic ball 12, thereby improving the stability of the limitation.
