[0048] Please refer to the attached document. Figures 1-5 This application provides a support base rotation assembly 100, which is applied to a twisting machine and is used to count the number of rotations by the user.

[0049] Please refer to the attached document. Figures 1-5 In this embodiment, the support base rotation assembly 100 includes a base 10, a support base 20, a magnetic element 30, and a first circuit board 40. The base 10 is used to lay on a table or the ground. The base 10 is provided with a rotating seat 11. The support base 20 is rotatably connected to the base 10 and rotates along the axis of the rotating seat 11. The magnetic element 30 is installed on the rotating seat 11 and is stationary relative to the base 10. The first circuit board 40 is accommodated in the internal space of the support base 20 and is installed on the support base 20. The first circuit board 40 integrates a Hall sensor 41, which is located on one side of the magnetic element 30. The Hall sensor 41 adjusts its position as the support base 20 rotates and has a Hall effect with the magnetic element 30, so as to count the number of rotations of the support base 20 relative to the base 10 through the Hall effect, thereby facilitating the counting of the user's rotations and avoiding the inability to count the number of rotations of the support base 20 relative to the base 10, thus improving the rotation convenience of the support base rotation assembly 100.

[0050] Please refer to the attached document. Figures 1-5 In this embodiment, the base 10 serves as the supporting part of the support seat rotation assembly 100, and the base 10 is used to support the support seat 20, the magnetic component 30, and the first circuit board 40. The base 10 is used to be laid on a table or the ground so that the support seat rotation assembly 100 can be placed flat on the table or the ground through the base 10; the base 10 is provided with a rotating seat 11, which is exposed on the upper surface of the base 10.

[0051] The support base 20 is disposed on the upper side of the base 10. The support base 20 is rotatably connected to the base 10 and rotates along the axis of the rotating seat 11 to facilitate adjustment of the position of the support base 20 relative to the base 10.

[0052] The magnetic component 30 is positioned on the rotating base 11 and is mounted on the rotating base 11, remaining stationary relative to the base 10; this ensures that the position of the magnetic component 30 relative to the base 10 remains unchanged.

[0053] The first circuit board 40 is housed within the internal space of the support base 20 and is mounted on the support base 20. The first circuit board 40 integrates a Hall sensor 41, which is located above the magnetic component 30. The Hall sensor 41 adjusts its position as the support base 20 rotates and interacts with the magnetic component 30 through Hall sensing. This allows for the counting of the number of rotations of the support base 20 relative to the base 10, thus facilitating the counting of the user's rotations and avoiding the inability to count the number of rotations of the support base 20 relative to the base 10. This improves the ease of rotation of the support base rotation assembly 100.

[0054] Please refer to the attached document. Figures 1-5 In this embodiment, the rotating base 11 is provided with a mounting groove 11a, which is recessed from top to bottom by the rotating base 11. The magnetic component 30 is mounted in the mounting groove 11a. This allows the inner wall of the mounting groove 11a to restrict the magnetic component 30, ensuring the positional accuracy of the magnetic component 30 relative to the rotating base 11. The Hall sensor 41 is positioned above the magnetic component 30. The Hall sensor 41 and the magnetic component 30 are stacked in the vertical direction, allowing the Hall sensor 41 to sense the magnetic component 30 from top to bottom. This facilitates Hall sensing between the Hall sensor 41 and the magnetic component 30, enabling the counting of the number of rotations of the support base 20 relative to the base 10. This facilitates the counting of the user's rotations, avoiding the inability to count the number of rotations of the support base 20 relative to the base 10, and improving the rotation convenience of the support base rotating assembly 100.

[0055] Please refer to the attached document. Figures 1-5 In this embodiment of the application, when the mounting groove 11a is arranged in a ring, the magnetic component 30 is sleeved in the mounting groove 11a and positioned and connected with the rotating seat 11; so that the inner sidewall of the mounting groove 11a restricts the different positions of the magnetic component 30 respectively, ensuring the positional accuracy of the magnetic component 30 relative to the rotating seat 11 and avoiding the positional offset of the magnetic component 30 relative to the rotating seat 11.

[0056] During rotation, the Hall sensor 41 remains directly above the magnetic component 30 and continuously exhibits Hall effect sensing with the magnetic component 30. This ensures the vertical position of the Hall sensor 41 and the magnetic component 30, facilitating the counting of rotations of the support base 20 relative to the base 10 through Hall effect sensing. This makes it easier to count the number of rotations by the user, avoiding the inability to count the number of rotations of the support base 20 relative to the base 10, and improving the ease of rotation of the support base rotation assembly 100.

[0057] Please refer to the attached document. Figures 1-5In this embodiment, the rotating base 11 is provided with a positioning arm 111, which is disposed on the periphery of the mounting groove 11a. The positioning arm 111 is provided with a positioning part 1111, which is located above the mounting groove 11a and engages with the magnetic component 30. This allows the positioning part 1111 to restrict the movement of the magnetic component 30, thereby facilitating the positioning arm 111 to achieve positioning connection of the magnetic component 30 relative to the rotating base 11, ensuring that the position of the magnetic component 30 relative to the rotating base 11 remains unchanged. Optionally, there are two positioning arms 111, which are arranged opposite to each other and position the magnetic component 30 at different locations, ensuring the positioning stability of the magnetic component 30 relative to the rotating base 11.

[0058] Please refer to the attached document. Figures 1-5 In this embodiment, the positioning arm 111 extends upward from the side wall of the rotating seat 11, and the positioning part 1111 is located at the top of the positioning arm 111. The top of the positioning part 1111 is provided with a guide part 11111, which is arranged in an arc or at an incline. The magnetic component 30 enters the mounting groove 11a under the guidance of the guide part 11111 and is positioned by the positioning part 1111, so that the magnetic component 30 can enter the positioning part 1111 through the guide part 11111, thereby improving the smoothness of the installation of the magnetic component 30 relative to the positioning part 1111.

[0059] Please refer to the attached document. Figures 1-3 In this embodiment of the application, the first circuit board 40 integrates a corresponding button control unit 42; the support base 20 is provided with a first support part 21 and a second support part 22; the second support part 22 is connected to the first support part 21; the second support part 22 and the first support part 21 form a receiving cavity 21a, and the first circuit board 40 is received in the receiving cavity 21a; so that the first circuit board 40 can make full use of the space of the receiving cavity 21a, thereby facilitating the second support part 22 and the first support part 21 to protect the first circuit board 40.

[0060] The first support part 21 rotates relative to the base 10 to adjust its position relative to the base 10. The second support part 22 is disposed on the upper side of the first support part 21 and rotates with the rotation of the first support part 21. The second support part 22 is connected to a button 221. The button 221 is movable relative to the second support part 22 and is located on the upper side of the corresponding button control part 42. The button 221 can contact the corresponding button control part 42 and trigger the response of the button control part 42, so that the user can control the first circuit board 40 through the button control part 42 by pressing the button 221, thereby facilitating the output of different signals by the first circuit board 40.

[0061] Please refer to the attached document. Figures 1-3In this embodiment, the peripheral sidewall of the second support 22 is connected to a docking terminal 222. The docking terminal 222 is disposed on one side of the first circuit board 40 and electrically connected to the first circuit board 40, so that an external power supply can be electrically connected to the first circuit board 40 through the docking terminal 222, thereby facilitating the external power supply to the first circuit board 40.

[0062] Please refer to the attached document. Figures 1-3 In this embodiment, the first support portion 21 and the base 10 are arranged opposite to each other and form an annular groove 21b. The support seat rotation assembly 100 also includes at least one ball bearing module 50, which includes a plurality of balls 51. The plurality of balls 51 are located between the first support portion 21 and the base 10.

The plurality of balls 51 respectively roll and contact the first support portion 21 and the base 10, and can move in annularly along the annular groove 21b, so that the first support portion 21 can achieve a rotation effect relative to the base 10 through the ball bearing module 50, thereby improving the smoothness of the rotation of the support seat 20 relative to the base 10.

[0063] Please refer to the attached document. Figures 1-3 In this embodiment of the application, the second support part 22 is connected to a foot pad module 223, which includes a metal pad 2231 and a second circuit board 2232; the metal pad 2231 is installed on the second support part 22 and exposed on the upper surface of the second support part 22; so that the metal pad 2231 can guide the user's foot to step on the correct position.

[0064] The second support portion 22 is provided with a second through hole 22a and a receiving groove 22b. The receiving groove 22b communicates with the receiving cavity 21a through the second through hole 22a so that the conductive component of the first circuit board 40 located in the receiving cavity 21a extends to the receiving groove 22b through the receiving cavity 21a and the second through hole 22a. The first circuit board 40 located in the receiving cavity 21a is electrically connected to the second circuit board 2232 located in the receiving groove 22b so that the first circuit board 40 and the second circuit board 2232 can transmit signals.

[0065] The second circuit board 2232 integrates a heating element 22321 or an EMS conductive element 22322. When the second circuit board 2232 integrates the heating element 22321, the heating element 22321 outputs heat in the working state, and this heat is conducted to the metal pad 2231, so that the metal pad 2231 can heat the user's soles. This ensures that the user's soles are heated and massaged during use, and improves the massage effect of the support base rotating assembly 100.

[0066] When the second circuit board 2232 integrates the EMS conductive part 22322, the EMS conductive part 22322 is electrically connected to the metal pad 2231 and can perform EMS massage on the user's soles, ensuring that the user's soles are massaged during use and improving the massage effect of the support seat rotating assembly 100.
