[0150] In Example 1, the reset disk is installed between the ball joint shaft and the top cover, and the reset spring is installed between the reset disk and the top cover, which results in a small installation space for the reset spring and makes it difficult to achieve an ideal reset force. Moreover, it is difficult to install two different reset springs. It is also difficult to achieve other reset methods such as using a gas cylinder, and therefore, some improvements are made in the following design. Example 2

[0151] Please refer to Figures 21-33 The present embodiment provides a double-shaft downward-mounted self-resetting Hall rocker, which comprises a top cover two 4a, an outer cylinder 5, a ball joint base two 6a, a bottom cover 7, an extension rod two 8a, half-toothed screws 9, a reset disk two 10a, a ball joint shaft two 11a, a ball joint cover 12, a square hole ball 13, a reset spring 14, a circuit board support frame 16, and a ball joint shaft upper pressing plate 17.

[0152] As Figures 23-24As shown, the upper end of the top cover two 4a is a square opening 4a13, and the member composed of the extension rod two 8a and the ball joint shaft two 11a swings in the square opening. The lower end surface 4a15 of the top cover two is provided with an annular groove one 4a14, which cooperates with the outer cylinder 5, thereby increasing the sealing of the connection and the reliability of the installation. In addition, the top cover two does not directly cooperate with the ball joint shaft, but contacts the upper end surface 1702 of the upper pressing plate 17 of the ball joint shaft through the lower end surface 4a15 thereof, so that the ball joint surface 1701 of the upper pressing plate cooperates with the shell-shaped half-sphere outer surface of the ball joint shaft two, thereby limiting the Z-axis position of the ball joint shaft two, and thus simplifying the structural design of the top cover. The rest of the features of the top cover two are the same as those of example 1.

[0153] The outer cylinder 5 has the same features as those of example 1.

[0154] As shown, Figures 25-26 the hollow sphere at the upper end of the ball joint base two 6a is similar to that of example 1, and the outer surface or guide surface 6a13 of the connecting column below the hollow sphere is used to cooperate with the reset disc inner surface one 0a04a of the reset disc two 10a to form a moving pair, thereby providing a certain guiding effect for the reset disc two. The spring mounting groove one 6a15 is provided on the upper end surface of the ball joint base main body, which cooperates with the spring mounting groove two 10a02a of the reset disc, thereby fixing the upper and lower end surfaces of the reset spring. A special support frame mounting cavity 6a14 is provided in the lower cavity 6a17 of the ball joint base two, which is used to install the circuit board support frame 16, and a support frame mounting groove one 6a16 is provided beside the mounting position, thereby fixing the support frame.

[0155] The bottom cover 7 has the same features as those of example 1.

[0156] As shown, Figure 27 the upper end of the extension rod two 8a is provided with a connecting internal thread 8a02a, which is used to connect with the corresponding external thread handle; the upper end outer surface is provided with a hexagonal head 8a07, which is convenient for fastening the extension rod when connected with the handle; and a dust cover fixing groove 8a06 is provided below the hexagonal head, so that the dust cover is tightly connected with the extension rod. The rest of the features are the same as those of example 1.

[0157] As shown, Figure 28 the reset disc 10a not only cooperates with the inner surface of the outer cylinder 5 through the outer surface one 10a03a to form a moving pair, but also cooperates with the connecting column outer surface one 6a13 of the ball joint base through the inner surface one 10a04a to form a moving pair, thereby further improving the stability of the reset disc during movement. The screw rod mounting hole four 10a01a is used to pass through the connecting member. The rest of the features are the same as those of example 1.

[0158] As shown, Figure 29As shown, the upper end pin hole three 11a01a of the ball sub shaft two 11a is provided with an annular groove two or ring groove structure 11a11a for installing a stop ring. When the ball sub shaft two and the extension rod two 8a are fixed by the pin, the stop ring is installed in the annular groove to prevent the pin from accidentally slipping off, thereby enhancing the reliability of the connecting components. In this example, the annular flange two 11a07a of the ball sub shaft shell cooperates with the reset disc, and the reset disc is below and the flange is above. The remaining features are the same as in Example 1.

[0159] The ball sub cover 12 has the same features as in Example 1.

[0160] The square hole ball 13 has the same features as in Example 1.

[0161] As Figures 30-31 As shown, the circuit board support frame 16, in this embodiment, the reset spring 14 and the reset disc 10 are both installed at the lower end of the rotating device (referring to the ball sub shaft two), so there is a large installation space, thereby providing more space range for the selection of the reset spring 14. However, the distance between the center of the rotating device and the bottom cover 7 increases, resulting in the need to lift the magnetic field or position detection device to make it closer to the rotation center, thereby improving the detection effect of the sensor device. The circuit board support frame is in a cylindrical structure, and the circuit board installation position 1603 is used to install the circuit board with a magnetic sensing chip (or called Hall circuit board); and by setting corresponding isolation devices or ferromagnetic metal sheets in the upper cavity, the external magnetic field is reduced to avoid affecting the detection circuit. When the circuit board support frame is installed to the support frame installation cavity 6a14 of the ball sub base two 6a, the outer wall 1604 cooperates with the inner wall of the support frame installation cavity of the ball sub base, and the flange 1601 of the circuit board support frame cooperates with the support frame installation groove one 6a16 of the ball sub base, and is fixed by screws. The circuit board support frame side is also provided with a wire groove 1602 for leading out the wires on the circuit board.

[0162] As Figures 32-33 As shown, the ball sub shaft upper pressing plate 17 adopts a ring structure, and the outer ring of the ring structure is provided with a plurality of through holes two 1703 for passing through the half toothed screw rod 9. The inner ring of the lower end surface 1704 of the ball sub shaft upper pressing plate is designed as an embedded ball sub surface 1701, and the ball center of the ball sub surface 1701 coincides with the rotation center of the ball sub shaft, so that the ball sub surface 1701 cooperates with the shell-shaped half spherical outer surface 11a06a of the ball sub shaft, thereby increasing the contact area between them and improving the wear resistance. In addition, the upper end surface 1702 of the ball sub shaft upper pressing plate is in contact with the lower end surface 4a15 of the top cover, which simplifies the structure design of the top cover and ensures the reliability of the structure.

[0163] A double-axis lower-mounted self-resetting Hall rocker installation method and use principle of the present embodiment: First, install the spherical joint ball 13 and the spherical joint cover 12 to the spherical joint base 6a, which is similar to the steps in Example 1. Then, install the reset disc 10a to the guide surface 6a13 of the spherical joint base, and install the reset spring 14 between the spring installation groove two 10a02a of the reset disc and the spring installation groove one 6a15 of the spherical joint base. Press the spherical joint shaft two 11a to the reset disc, and apply lubricating grease between the inner surface one 0a04a of the reset disc and the outer surface one 6a13 of the connecting column of the spherical joint base, and between the reset disc and the annular flange two 11a07a of the spherical joint shaft, to ensure reduced wear and smooth operation.

[0164] Next, install the spherical joint shaft upper pressing plate 17 to the spherical joint shaft, and ensure that the spherical joint surface 1701 of the spherical joint shaft upper pressing plate matches the shell-shaped half-sphere outer surface 11a06a of the spherical joint shaft. Then, install the circuit board to the circuit board installation position 1603 of the circuit board support frame 16, and assemble it into the support frame installation cavity 6a14 of the spherical joint base. Use the flange 1601 of the circuit board support frame to dock with the support frame installation groove one 6a16 of the spherical joint base, and use screws to fix it.

[0165] Then, fit the outer cylinder 5 to the spherical joint base.

[0166] Finally, install the top cover on the spherical joint shaft upper pressing plate, and use the half-threaded screw 9 to connect the top cover 4, the spherical joint shaft upper pressing plate 17, the reset disc two 10a, the outer cylinder 5, and the bottom cover 7. This part of the installation process is similar to the steps in Example 1.

[0167] This double-axis downward-mounted self-resetting Hall rocker can improve the swing range of the spherical joint shaft, facilitate the installation, selection, and adjustment of the reset spring, expand the selection range of the reset spring, and increase the diameter of the rod-shaped part of the spherical joint shaft, thereby improving its strength and stiffness.

[0168] The details not described in the present application are known to those skilled in the art.

[0169] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the examples, those skilled in the art should understand that the technical solutions of the present application can be modified and replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application. Example 3

[0170] Please refer to Figures 34-36 , the present embodiment provides a double-axis downward-mounted two-stage self-resetting Hall rocker, which includes all the parts of Example 2, wherein the reset disc three 10b and the spherical joint base three 6b have different features from Example 2. In addition, it also includes the reset spring two 18.

[0171] In the ball joint base 3 6b, a stepped spring mounting groove 3 6b18 is provided within the spring mounting groove 4 6b15. A return spring 2 18, with a smaller diameter than the return spring, can be installed in the spring mounting groove 3. The outer surface 6b13 of the connecting post mates with the inner cylindrical surface 10b04 of the return plate to form a moving pair. The remaining features are the same as those of Example 2.

[0172] like Figure 35 As shown, in the reset disk 3 10b, a spring action surface 10b05 is provided within the spring mounting groove 2 10b02. The reset spring 2 18 acts there. The remaining features are the same as those of Example 2. 10b01 is a through hole extending through the upper and lower surfaces of the reset disk 3 10b, for receiving a connector. 10b04 is the inner cylindrical surface of the reset disk. 10b04 mates with 6b13 of the ball joint base 3 6b. 10b03 is the outer cylindrical surface of the reset disk. 10b03 mates with the outer cylinder. The screw mounting hole 5 10b01 is for receiving a connector.

[0173] The height of the second return spring 18 is lower than the distance from the third return spring mounting slot 6b18 to the spring action plane 10b05. This ensures that compression of the second return spring 18 begins only after the third return disc 10b has moved downward a certain distance. Specifically, within a certain angular range, the second ball countershaft 11a is acted upon by the return spring 14, resulting in a relatively low operating force. Beyond this angular range, however, both the return spring 14 and the second return spring 18 act simultaneously to reset the ball countershaft 11a, resulting in a relatively high operating force. This results in two operating stages, depending on the swing angle. Example 4

[0174] See also Figures 37-40 This embodiment provides a dual-axis bottom-mounted feedback-type self-resetting Hall effect rocker, comprising all the components of Example 2, with the exception of the ball-pair base 24 6c and bottom cover 24 7c. Furthermore, it includes a cylinder body 19 and a cylinder piston rod 20.

[0175] like Figures 38-39 As shown, the ball-pair base 4 (6c) has four through-holes (3) (6c19) evenly distributed along its circumference on its large end surface. Cylinder positioning holes (6c20) are provided along through-holes (3). The remaining features are identical to those of Example 2. The support frame mounting groove (2) (6c16) is used to mount the flange of the circuit board support frame. The lower cavity (6c17) of the ball-pair base 4 can be used to mount the main controller or other components. The outer surface (6c13) of the connecting post forms a moving pair with the inner surface (10a04a) of the reset plate (10a) of the cover embodiment. The screw mounting hole (6c02) is used to mount the connector.

[0176] like Figure 40The bottom cover four 7c is provided with cylinder mounting holes 7c08 on the end face, and the inside of the cylinder mounting holes is provided with threads. The cylinder mounting holes are evenly distributed on the circumference of the end face of the bottom cover four 7c. The outer surface two 7c07 is a cylindrical outer surface. The remaining features are the same as those of example 2.

[0177] The cylinder 19 is connected and fixed with the bottom cover four 7c through the cylinder mounting holes 7c08 on the bottom cover four 7c, and the axial position of the cylinder 19 is determined through the cylinder positioning holes 6c20 on the ball joint base four 6c.

[0178] The piston rod of the cylinder 19 acts on the reset disc two 10a through the through hole three 6c19 of the ball joint base four 6c. If a certain air pressure is applied to the four cylinders 19, the reset disc two 10a will be subjected to the force of the piston rod of the four cylinder pistons 20 in addition to the force of the reset spring 14. If the air pressure is adjustable within a certain range, the operating force of the rocker is also adjustable within a certain range. If the air pressure is controlled by an external signal, the reset force of the rocker can be changed with the change of the air pressure when the external signal drives the cylinder piston 20 to work at different air pressures. When there is no external signal to drive the cylinder piston 20, the reset force of the rocker is small. Or, when there is no external signal to drive the cylinder piston 20, the reset force of the rocker is determined only by the reset spring; when the size of the external signal is determined by the load, the effect of load feedback can be achieved by adjusting the pressure of the cylinder through the external signal. Example 5

[0179] Please refer to Figure 41 , the embodiment provides a double-shaft downward-mounted double-stage self-resetting Hall rocker, which comprises all the parts in example 4. In addition, the embodiment also comprises a cylinder reset spring 21.

[0180] The cylinder piston 20 is provided with a reset force by the cylinder reset spring.

[0181] The piston rod of the cylinder piston 20 can only exert a reset force on the reset disc after the reset disc two 10a moves downward by a certain distance. That is, the ball joint shaft two 11a is acted on by the reset spring 14 within a certain angle range, and the operating force is small; when the angle is greater than the angle range, the reset is performed by the reset spring 14 and the piston rod of the cylinder piston 20 at the same time, and the operating force is large. Thus, two operating stages are formed according to different swing angles. Example 6

[0182] Please refer to Figures 42-46 , the embodiment provides a double-shaft downward-mounted edge clamping self-resetting Hall rocker, which comprises all the parts in example 2. In addition, the embodiment also comprises a clamping rod 22, a clamping rod fixing pin 23, a positioning bead 24, and a positioning bead pressing block 25.

[0183] As Figure 45As shown, the spring mounting groove five 6d15 of the ball pair base five 6d has four positioning bead mounting grooves 6d21 evenly arranged around the circumference, and four clamping hole 6d22 are arranged at the corresponding positions outside the positioning bead mounting grooves 6d21. The positioning bead 24 is mounted in the positioning bead mounting groove 6d21 and is pressed by the positioning bead pressing block 25. The outer surface of the connecting column four 6d13 can be in contact with the inner surface of the reset disc 10d04 to form a moving pair.

[0184] As shown in Figure 47 The clamping rod 22 is a cylindrical part, the upper end has a pin hole two 2201, the middle part has a clamping rod positioning step surface 2204 arranged at the lower position. The lower end has a clamping groove 2202, and the lowermost end has a clamping protrusion 2203 with a diameter larger than that of the clamping groove 2202.

[0185] As shown in Figures 43-44 The reset disc 10d has clamping rod mounting holes 10d06 evenly distributed around the circumference, and pin holes one 10d08 passing through the clamping rod mounting holes 10d06. The upper surface of the reset disc is a reset inclined surface one 10d13. The reset inclined surface one 10d13 is a tapered reset inclined surface. The upper surface of the reset disc is provided with four clamping protrusions 10d07 evenly distributed along the circumferential direction. The spring mounting groove six 10d02 is used to mount the reset spring. The clamping rod positioning groove 10d09 is matched with the clamping rod positioning step surface 2204 of the clamping rod 22 for installation. The screw mounting hole seven 10d01 is used to pass through the connecting piece.

[0186] As shown in Figure 46 The lower surface of the ball pair shaft five 11d is a reset inclined surface two 11d14. The reset inclined surface two 11d14 is an inverted tapered surface. The lower surface of the ball pair shaft five 11d is provided with four reset protrusions two 11d12 and reset protrusion inclined surfaces 11d13 evenly distributed along the circumferential direction.

[0187] When the reset disc 10d moves downward, the four clamping rods 22 fixed thereto also move downward at the same time, and the lower end of the clamping rod 22 moves in the clamping hole 6d22 of the ball pair base five 6d. Due to the action of the positioning bead 24, when the clamping rod 22 moves downward by a certain distance, it will be resisted by the positioning bead 24. When it continues to move downward until the positioning bead 24 can be embedded in the clamping groove 2202 of the clamping rod 22, the resistance will be greatly reduced. This process realizes the effect of clamping feeling at the end of the movement of the reset disc 10d during downward movement. The positioning bead 24 is a steel bead pressed by a compression spring or an elastic member.

[0188] When assembled, the reset protrusion one 10d07 and the reset slope one 10d13 of the reset disc 10d are respectively fitted with the reset protrusion two 11d12 and the reset slope two 11d14 of the ball sub-shaft five 11d. This fitting ensures that when the ball sub-shaft five 11d swings to the edge of the square opening 4a13 of the mounting plate 4, the reset disc 10d can move downward to the limit position. That is, when the ball sub-shaft 11d swings to the edge of the square opening 4a13 of the mounting plate 4, the trigger catch is triggered, and the operator will get an obvious prompt or feedback.

[0189] When the ball sub-shaft five 11d swings to the diagonal position of the square opening 4a13 of the mounting plate 4, the ball sub-shaft five 11d presses the reset disc 10d, and the reset disc 10d drives the catch rod 22 to move, triggering the catch, and the operator will get an obvious prompt or feedback.

[0190] Although the present application has been described with reference to the embodiments above, various modifications can be made thereto and equivalents can be substituted therefor without departing from the scope of the present application. In particular, features of the disclosed embodiments can be combined together in any manner, as long as there is no structural conflict. Therefore, the present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
