Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] It should be noted that in the description of this utility model, if the terms "first" or "second" appear, they are only used for the convenience of describing different components or names, and should not be construed as indicating or implying a sequential relationship, relative importance, or implicitly specifying the number of technical features indicated. Therefore, a feature specified with "first" or "second" may explicitly or implicitly include at least one of those features.

[0041] This utility model embodiment proposes a control box 100, which can be electrically connected to the physiotherapy patch 60 to control the operation of the physiotherapy patch 60.

[0042] Please refer to the following: Figures 1 to 6 The control box 100 provided in this embodiment of the present invention will now be described. The control box 100 includes a housing 10, a battery 20, a control board 30, an adapter board 40, and a terminal group 50. The battery 20, the control board 30, and the adapter board 40 are installed inside the housing 10. The control board 30 is used to control the physiotherapy patch 60, and the control board 30 is electrically connected to the battery 20. The adapter board 40 is electrically connected to the control board 30, and the adapter board 40 and the control board 30 are located on opposite sides of the battery 20 along the thickness direction. The terminal group 50 is used to be electrically connected to an external circuit. The terminal group 50 is installed on the housing 10, and the terminal group 50 is located on the side of the adapter board 40 away from the control board 30, and the terminal group 50 is electrically connected to the adapter board 40.

[0043] Terminal assembly 50 may include two or more magnetic electrodes, conductive sheets, electrode caps, or electrode posts, etc. When the control box 100 is connected to the therapy patch 60, terminal assembly 50 can be electrically connected to the magnetic terminal 61 of the therapy patch 60 to conduct the circuit, thereby enabling control of the therapy patch 60. When the control box 100 is connected to the charging base, terminal assembly 50 can be electrically connected to the output terminal of the charging base to charge the control box 100. One end of terminal assembly 50 protrudes from the housing 10 for connection to external circuitry, while the other end extends into the housing 10 for electrical connection to the adapter plate 40. Terminal assembly 50 can be fixed to the housing 10 by injection molding, gluing, or other methods to maintain the seal of the housing 10.

[0044] In this embodiment of the invention, the control board 30 and the adapter board 40 are located on opposite sides of the battery 20. The adapter board 40 is electrically connected to the terminal group 50. During assembly, the terminal group 50 can be connected and fixed to the housing 10 first, without directly fixing the control board 30 to the housing 10, which facilitates the connection of the terminal group 50 and the sealing of the housing 10. The adapter board 40 and the control board 30 are set separately, and the battery 20 is electrically connected to the control board 30, making the assembly of the terminal group 50 and the assembly of the battery 20 relatively independent. After the terminal group 50 is fixed to the housing 10, the battery 20 can be soldered and assembled to the control board 30. Finally, the electrical connection between the terminal group 50 and the control board 30 is achieved through the electrical connection between the control board 30 and the adapter board 40, which facilitates the assembly of the battery 20. Moreover, the separation of the adapter board 40 and the control board 30, compared to using a single circuit board, helps to reduce the area of ​​the control board 30, which in turn helps to reduce the cross-sectional area of ​​the housing 10, making the control box 100 more compact.

[0045] Optionally, the terminal group 50 and the adapter plate 40 are detachably electrically connected, such as by abutment, snap-fit, or bolt connection; the control plate 30 and the adapter plate 40 are also detachably electrically connected, such as by abutment, snap-fit, or bolt connection. This facilitates the assembly of the terminal group 50 and the battery 20 and helps to reduce the length of the connecting wires between the battery 20 and the control plate 30.

[0046] In some embodiments, please refer to Figures 2 to 4The terminal group 50 includes two first electrodes 51 and two second electrodes 52. The two first electrodes 51 are used for electrical connection with the physiotherapy patch 60, and the two second electrodes 52 are used for electrical connection with the charging base. The two first electrodes 51 and the two second electrodes 52 are arranged at intervals. In this way, the two first electrodes 51 form a discharge port, and the two second electrodes 52 form a charging port, which can be electrically connected to an external circuit to realize the charging and discharging of the battery 20. The interval arrangement of the two first electrodes 51 and the two second electrodes 52 helps to improve the safety of the control box 100 during charging and discharging and reduces interference between the charging circuit and the discharging circuit; the interval arrangement of the two first electrodes 51 and the two second electrodes 52 can prevent short circuits in the control box 100 during charging and discharging.

[0047] In some embodiments, please refer to Figures 2 to 4 A positioning groove 101 is provided on the outer side of the housing 10 near the terminal group 50. The positioning groove 101 is used to fit with the charging base. Two second electrodes 52 are spaced apart in the positioning groove 101, and two first electrodes 51 are located on opposite sides of the positioning groove 101. This facilitates the alignment of the charging base and the control box 100 when they are electrically connected. When a positioning platform 63 is provided on the physiotherapy patch 60, the positioning platform 63 can also cooperate with the positioning groove 101 to facilitate the alignment of the physiotherapy patch 60 and the control box 100.

[0048] Optionally, the positioning groove 101 is open at one end along its length, and the two second electrodes 52 are arranged along the length of the positioning groove 101; the two first electrodes 51 are located on opposite sides of the positioning groove 101 along its width. This improves the stability of the connection between the control box 100 and the physiotherapy patch 60 or the charging base, prevents factors such as vibration from affecting the stability of the electrical connection during charging and discharging, and also helps to prevent mistaken identification.

[0049] In some embodiments, please refer to Figures 2 to 4 One end of the first electrode 51 is confined within the housing 10, and one end of the second electrode 52 is confined within the housing 10. The adapter plate 40 has two first conductive disks 41 and two second conductive disks 42 on the side near the terminal group 50. The two first conductive disks 41 correspond one-to-one with the two first electrodes 51, and the two second conductive disks 42 correspond one-to-one with the two second electrodes 52. Two first elastic elements 45 and two second elastic elements 46 are installed inside the housing 10. The two ends of each first elastic element 45 are in contact with and connected to the corresponding first electrode 51 and first conductive disk 41, respectively. The two ends of each second elastic element 46 are in contact with and connected to the corresponding second electrode 52 and second conductive disk 42, respectively. By using the first elastic elements 45 and second elastic elements 46, a detachable connection can be achieved between the adapter plate 40 and the first electrodes 51 and second electrodes 52. This allows the first electrodes 51 and second electrodes 52 to be fixed to the housing 10 first, and then the adapter plate 40 to be assembled.

[0050] Optionally, a first limiting ring is provided at one end of the first electrode 51 near the interior of the housing 10. A first opening is provided on the housing 10, and the first electrode 51 passes through the first opening. The diameter of the first limiting ring is larger than the diameter of the first opening, and the first limiting ring is located at the end of the first opening near the interior of the housing 10. The other end of the first electrode 51 protrudes from the first opening. In this way, one end of the first electrode 51 can be confined within the housing 10.

[0051] Optionally, a second limiting ring is provided at one end of the second electrode 52 near the interior of the housing 10. A second opening is provided on the housing 10, and the second electrode 52 passes through the second opening. The diameter of the second limiting ring is larger than the diameter of the second opening, and the second limiting ring is located at one end of the second opening near the interior of the housing 10. The other end of the second electrode 52 protrudes from the second opening. In this way, one end of the second electrode 52 can be confined within the housing 10.

[0052] In some embodiments, please refer to Figures 2 to 4 The first electrode 51 has a first positioning hole 511 at one end near the adapter plate 40. The first elastic element 45 is a first spring, and one end of the first spring is inserted into the first positioning hole 511. This facilitates positioning of the first spring and prevents it from separating from the first electrode 51. The first spring electrically connects the first electrode 51 and the first conductive disk 41, which helps maintain the stability of the electrical connection between the two ends of the first elastic element 45. Of course, the two ends of the first spring can be welded to the first electrode 51 and the first conductive disk 41 respectively to reduce the resistance at the connection point.

[0053] In some embodiments, please refer to Figures 2 to 4 The second electrode 52 has a second positioning hole 521 at one end near the adapter plate 40. The second elastic element 46 is a second spring, and one end of the second spring is inserted into the second positioning hole 521. This facilitates positioning of the second spring and prevents it from separating from the second electrode 52. The second spring electrically connects the second electrode 52 and the second conductive disk 42, which helps maintain the stability of the electrical connection between the two ends of the first elastic element 45. Alternatively, the two ends of the second spring can be welded to the second electrode 52 and the second conductive disk 42 respectively to reduce the resistance at the connection point.

[0054] In some embodiments, please refer to Figures 2 to 5 The housing 10 is provided with two first isolation rings 112 and two second isolation rings 113. Each first electrode 51 has a first isolation ring 112 around its outer ring, and each second electrode 52 has a second isolation ring 113 around its outer ring. In this way, the first electrode 51 and the second electrode 52 can be isolated from each other to prevent short circuit between them; moreover, the positions of the first spring and the second spring can be restricted, which is beneficial to maintaining the stability of the positions of the first spring and the second spring.

[0055] In some embodiments, please refer to Figures 2 to 4 The adapter plate 40 has a third conductive disk 43 on the side near the control plate 30, and the control plate 30 has a third elastic element 31. The third elastic element 31 abuts against the third conductive disk 43 and conducts electricity, and the third conductive disk 43 is electrically connected to the first conductive disk 41. This allows for a detachable connection between the adapter plate 40 and the control plate 30, eliminating the need for wire bonding during assembly and making it more convenient. Optionally, the third conductive disk 43 is electrically connected to the first conductive disk 41, which facilitates the electrical connection between the first electrode 51 and the third elastic element 31.

[0056] In some embodiments, please refer to Figures 2 to 4 The adapter plate 40 has a fourth conductive disk 44 on the side near the control plate 30, and the control plate 30 has a fourth elastic element 32. The fourth elastic element 32 abuts against the fourth conductive disk 44 and conducts electricity. The fourth conductive disk 44 is electrically connected to the second conductive disk 42. This allows for a detachable connection between the adapter plate 40 and the control plate 30, eliminating the need for wire bonding during assembly and making the process more convenient. Optionally, the fourth conductive disk 44 is electrically connected to the second conductive disk 42, which facilitates the electrical connection between the second electrode 52 and the fourth elastic element 32.

[0057] Optionally, there are two third elastic members 31 and two fourth elastic members 32, arranged in an array around the battery 20. This helps to maintain a balanced force between the adapter plate 40 and the control plate 30, improving the stability of the connection, and also helps to avoid the battery 20 and limit its movement.

[0058] In some embodiments, please refer to Figures 2 to 4 The first electrode 51 is a magnetic component, used to engage with the magnetic terminal 61 for magnetic attraction. This facilitates a detachable electrical connection between the control box 100 and the therapeutic patch 60. Specifically, the first electrode 51 can be made of a non-magnetic material, such as a non-magnetic iron component or an iron-cobalt-nickel alloy component. Of course, in other embodiments, the first electrode 51 can also be a magnet, so as to magnetically attract with the magnetic terminal 61.

[0059] In some embodiments, please refer to Figures 2 to 4 The second electrode 52 is a magnetic component, used to engage with the magnetic terminal 61 for magnetic attraction. This facilitates a detachable electrical connection between the control box 100 and the charging dock. Specifically, the second electrode 52 can be made of a non-magnetic material, such as a non-magnetic iron component or an iron-cobalt-nickel alloy component. Of course, in other embodiments, the second electrode 52 can also be a magnet, so as to magnetically attract with the magnetic terminal 61.

[0060] In some embodiments, please refer to Figures 2 to 4 The control board 30 and the adapter board 40 are connected by conductive spring pins. This enables a detachable electrical connection between the control board 30 and the adapter board 40, avoiding interference caused by the electrical connection between the adapter board 40 and the control board 30 and the welding of the battery 20.

[0061] Specifically, the third elastic element 31 is a conductive spring pin, one end of which is welded to the control board 30, and the other end of which is connected to the third conductive disk 43; the fourth elastic element 32 is a conductive spring pin, one end of which is welded to the control board 30, and the other end of which is connected to the fourth conductive disk 44. This ensures a stable electrical connection between the control board 30 and the adapter board 40.

[0062] In some embodiments, please refer to Figures 2 to 4 The adapter plate 40 has a recessed groove 47 on one side, and the housing 10 has a misalignment strip 111 for fitting into the recessed groove 47. The misalignment strip 111 is arranged along the height direction of the housing 10. This prevents the adapter plate 40 from being installed backwards.

[0063] In some embodiments, please refer to Figures 2 to 4 A button 33 is provided on the side of the control board 30 away from the adapter plate 40, and a button cap 13 is installed on the housing 10 opposite the button 33.

The physiotherapy patch 60 can be a phototherapy patch, a heat therapy patch, etc., thereby enabling phototherapy or heat therapy.

[0067] Optionally, the control box 100 and the therapy patch 60 are detachably electrically connected. This facilitates the charging, replacement, and storage of the control box 100.

[0068] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 6 The physiotherapy patch 60 is provided with magnetic terminals 61, which are used to magnetically engage with the terminal group 50. Optionally, there are two magnetic terminals 61, and the two magnetic terminals 61 correspond to the two first electrodes 51 respectively.
