Description

Technical Field

[0001] This utility model belongs to the technical field of electrical stimulation equipment, and in particular relates to a charging rack and charging circuit for an electrical stimulator. Background Technology

[0002] Neuromuscular stimulators are a technology that uses electrical stimulation to activate nerves and muscles; hence, they are also called electrical stimulators. They are commonly used in medical rehabilitation, sports training, and cosmetic skin tightening. The working principle of a neuromuscular stimulator is to send electrical pulses to specific muscle groups through an external device, simulating signals from the central nervous system, thereby causing muscle contraction.

[0003] Neuromuscular stimulators generally come in two types: wired and modular, suitable for different application scenarios. Existing modular neuromuscular stimulators contain a battery, which is placed on a charging stand after use for charging. Utility model patent CN219041428U discloses a charging stand for an electrical stimulation host, which can simultaneously meet the charging needs of multiple devices, but it is immobile and cannot record the usage status of each stimulator, making it inconvenient to use. Utility model patent CN208525651U discloses a low-frequency neuromuscular stimulator that, while capable of charging electrical stimulators, is flexible and cannot charge multiple devices simultaneously. Furthermore, it cannot charge the electrical stimulator while it is being moved.

[0004] Therefore, it is necessary to improve existing technologies to solve the above problems. Utility Model Content

[0040] In one embodiment of this utility model, such as Figures 1-3 As shown, a charging rack for an electrical stimulator device is provided, including a charging base 100, a trolley 200, and multiple charging plates 300.

[0041] The charging base 100 is provided with multiple receiving spaces 101 for placing the charging plate 300. In this embodiment, the charging base 100 has multiple steps 110 arranged side by side, each step 110 being stepped in a progressively decreasing height, and each step 110 having at least one receiving space 101. Baffles 120 are provided on both sides of each step 110. The charging base 100 is also provided with a transparent outer shell 130 to prevent dust accumulation, prevent the electrical stimulator from falling, and facilitate observation of the electrical stimulator's usage. In this embodiment, the transparent outer shell 130 is specifically made of acrylic material.

[0042] The trolley 200 is positioned below the charging base 100 to move the charging base 100, facilitating use by medical personnel. The trolley 200 includes a support platform 210, multiple casters 220, a shelf 230, a display device 240, and a connecting assembly 250. The shelf can be used to hold patient medical records, connecting cables, electrical stimulation devices, etc., but is not limited to these. The top of the support platform 210 is connected to the bottom of the charging base 100. The multiple casters 220 are located at the bottom of the support platform 210. The shelf 230 is located on one side of the support platform 210. The display device 240 is movably mounted on the support platform 210 and located beside the charging base 100. The display device 240 is electrically connected to the charging base 100 and is used to detect and display the charging and usage status of each external electrical stimulator. The connecting assembly 250 is located between the display device 240 and the support platform 210.

[0043] In this invention, the trolley 200 is detachably connected to the charging base 100, and the display device 240 is detachably connected to the support platform 210. Through this modular design, if a module malfunctions, it can be replaced individually without having to send the entire device back to the factory for repair, which facilitates maintenance.

[0044] The charging plate 300 is disposed on the charging base 100 and is electrically connected to the charging base 100. The charging plate 300 is provided with a plurality of charging slots 310. The periphery of the charging slots 310 is provided with a protruding edge 320. The connection between the protruding edge 320 and the charging slot 310 is provided with a ramp 330, making it more convenient to place the electrostimulator.

[0045] The charging plate 300 is provided with multiple magnetic structures (not shown in the figure), each of which is located below the corresponding charging slot 310 for magnetic connection with an external electrostimulator, making the connection between the electrostimulator and the charging plate 300 more secure and preventing it from falling off. In this embodiment, the magnetic structure is a magnet; when a magnet is provided inside the external electrostimulator, the magnetic structure is a magnet or a metal that can be attracted by a magnet.

[0046] In this embodiment, a metal sheet (not shown in the figure) is disposed inside the through hole 340, and the bottom of the electrical stimulator has a conductive pin. The conductive pin is connected to the metal sheet to achieve a detachable electrical connection. Combined with the magnetic attraction between the upper charging plate 300 and the electrical stimulator, a stable electrical connection can be achieved between the conductive pin and the metal sheet, i.e., a stable electrical connection between the electrical stimulator and the charging plate 300. When it is necessary to remove the electrical stimulator, the user simply needs to remove it.

[0047] Specifically, one end of the conductive needle is electrically connected to the control circuit board inside the electrical stimulator, while the other end extends out of the lower cover of the electrical stimulator. For example, the conductive needle is a spring probe, allowing it to slide and extend when subjected to pressure.

[0048] The bottom of the charging board 300 is detachably connected and fixed to the surface of the charging base 100. The charging board 300 is provided with a female connector 350, and the charging base 100 is provided with a male connector (not shown). The male connector and the female connector 350 are detachably connected, facilitating disassembly and repair when a single charging board 300 malfunctions without affecting the use of other charging boards 300. In another embodiment, the charging board 300 and the charging base 100 are connected via a double-ended connecting cable. Disconnecting the double-ended connecting cable allows the charging board 300 to be separated from the charging base. In yet another embodiment, the charging board 300 and the charging base 100 are directly connected via a wire.

[0049] In this embodiment, as Figures 4-5 As shown, the charging base 100 contains a main control module 140, which manages the connections between the multiple charging boards 300 and the electrostimulators, and transmits information from each electrostimulator to the display device 240 via wired or wireless means. The display device 240 in this embodiment can display the current battery level of each electrostimulator, whether it is charging normally, whether it is currently treating a patient, when and for how long a patient is being treated, and the stimulation intensity used by a patient, but is not limited to these. In another embodiment of this utility model, the display device 240 is a mobile handheld terminal, which is electrically connected to the charging base 300 via wired or wireless means. The mobile handheld terminal has display and operation functions.

[0050] In one embodiment of this utility model, a rechargeable battery (not shown in the figure) is provided inside the charging base 100. The rechargeable battery is electrically connected to the charging plate 300, which can provide power to the charging plate 300 during the movement of the trolley 200, ensuring that the electrical stimulator is not powered off and avoiding the display device 240 from being powered off and restarting, thus affecting its use.

[0051] In one embodiment of this utility model, the steps 110 are arranged in a triangle, with the middle step 110 having the greatest height, and the height of the remaining steps 110 decreasing sequentially from the middle to both sides, which makes it convenient for users to grasp the electrical stimulator from both sides.
