Modes for Carrying Out the Invention

[0015] Hereinafter, in combination with the drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present invention.

[0016] Referring to the handgrip shown in FIGS. 1 and 2, it includes an annular body 1, two electrode sheets 2, a control device 3 and a power supply device 4. Both of the two electrode sheets 2 are installed on the outer surface of the annular body 1, the control device 3 and the power supply device 4 are both installed inside the annular body 1, and both the two electrode sheets 2 and the power supply device 4 are electrically connected to the control device 3. The power supply device 4 also supplies power for the two electrode sheets 2. In this embodiment, the control device 3 may be a normal circuit board with control functions, and the power supply device 4 is a rechargeable battery. The section of the annular body 1 corresponding to the fingers of the hand is made of an elastic material. By grasping this section where the user can generate elastic strain, the muscle strength of the hand can be exercised. The two electrode sheets 2 are divided into a positive electrode sheet and a negative electrode sheet, and are installed on the outer surface of the annular body 1 with a space therebetween. In order to transmit an electrical stimulation signal to the muscle and realize the EMS function, these two electrode sheets 2 respectively correspond to the thenar muscle and the hypothenar muscle of the palm. That is, when both of the two positive electrode sheets 2 contact the palm, the conduction of the current is realized, and the two electrode sheets 2 transmit low-frequency electrical pulses to the thenar muscle group and the hypothenar muscle group respectively to simulate nerve signals and stimulate the thenar muscle group and the hypothenar muscle group to generate a contraction reaction, so as to promote the strengthening of the muscle fibers and the force growth of the thenar muscle group and the hypothenar muscle group.

[0017] In some possible embodiments, one of the electrode sheets 2 forms an arc angle protrusion 21 on the outer surface of the annular body 1. By abutting this arc angle protrusion 21 against the concave part of the palm between the thenar muscle and the hypothenar muscle, the tension between the electrode sheet 2 and the palm can be made closer, and the effect of electrical stimulation can be improved.

[0018] In some possible embodiments, the annular body 1 includes a rigid grip portion 11 and an annular silicone 12. The annular silicone 12 is fixedly attached to both ends of the rigid grip portion 11, which can not only increase the comfort of gripping but also play a role in certain buffering and protection. A mounting groove 111 is formed in the rigid grip portion 11, and both the control device 3 and the power supply device 4 are installed in the mounting groove 111. The electrode sheet 2 covers the outer surface of the rigid grip portion 11 and seals the opening of the mounting groove 111, thereby forming an integrated structure and improving the appearance and sealing performance of the handgrip.

[0019] In some possible embodiments, at least one heating sheet 5 is further installed in the annular body 1. The heating sheet 5 is electrically connected to the control device 3 and is installed at a position corresponding to the thenar muscle and / or the hypothenar muscle. This embodiment will be described by taking the structural design of two heating sheets 5 as an example. The two heating sheets 5 are respectively installed at positions corresponding to the thenar muscle and the hypothenar muscle. The heating sheet 5 generates heat under the control of the control device 3 to preheat the muscle or maintain the temperature of the muscle during exercise, thereby promoting blood circulation, improving the exercise effect, and reducing the risk of injury.

[0020] In some possible embodiments, a plurality of pressing portions 121 are installed on the side of the annular silicone 12 away from the rigid grip portion 11. Protrusions or depressions are formed on the pressing portions 121. These pressing portions 121 can provide an additional massage effect when grasped by the user and reinforce the diversity of the functions of the handgrip.

[0021] In some possible embodiments, in order to facilitate the attachment and fixation of the electrode sheet 2, the hand grip further includes a pole piece mounting portion 6, and the pole piece mounting portion 6 is in a sheet shape and made of a hard insulating material. The electrode sheet 2 can be fixedly attached to the outer surface of the pole piece mounting portion 6 by means such as adhesion, caulking or locking. The pole piece mounting portion 6 is locked and fixed to the hard grip portion 11 and abuts against the outer surface of the hard grip portion 11. In order to improve the touch feeling, the electrode sheet 2 is usually made of a thin metal sheet or a conductive silicone sheet. In this embodiment, by attaching the electrode sheet 2 to the pole piece mounting portion 6 made of a hard insulating material, not only can the touch feeling of the contact of the electrode sheet 2 be retained, but also the strength of its structure can be increased, and the problem that the electrode sheet 2 is deformed under pressure can be avoided.

[0022] In some possible embodiments, a control button 7 electrically connected to the control device 3 is installed at a position corresponding to the thumb of the hard grip portion 11. The user can conveniently operate or switch each function of the hand grip through the control button 7, for example, adjust the strength of the electrical stimulation and control the heating temperature.

[0023] In some possible embodiments, by making the surface of the electrode sheet 2 smooth, the friction and discomfort on the skin are reduced, and the comfort of use is improved.

[0024] In some possible embodiments, an electric charging port 8 and several indicator lamps 9 are further installed inside the annular main body 1. The electric charging port 8 is for charging the power supply device 4, and the indicator lamps 9 can display information such as the operating state and the battery level of the hand grip, which is convenient for the user to understand the running situation of the device.

[0025] In some possible embodiments, the positive electrode sheet is installed at a position corresponding to the hypothenar muscle of the annular main body 1, and the negative electrode sheet is installed at a position corresponding to the thenar muscle of the annular main body 1. Such a layout can more effectively realize the electrical stimulation to the thenar muscle and the hypothenar muscle and promote the balanced development of the muscles.

[0026] In actual use, the user holds the annular main body 1, aligns the positive electrode sheet with the hypothenar muscle position of the palm, aligns the negative electrode sheet with the thenar muscle position, strongly holds and presses the elastic material part of the annular main body 1 to exercise the grip strength. At the same time, the EMS function is activated through the control button 7. The control device 3 transmits an electrical stimulation signal to the electrode sheet 2, and the two electrode sheets 2 respectively transmit low-frequency electrical pulses to the thenar muscle group and the hypothenar muscle group to simulate nerve signals and stimulate the thenar muscle group and the hypothenar muscle group to generate a contraction reaction, thereby promoting the strengthening and force growth of the muscle fibers of the thenar muscle group and the hypothenar muscle group. The heating sheet 5 generates heat under the control of the control device 3, preheats the muscles or maintains the temperature, and further improves the safety and effectiveness of the exercise.

[0027] The hand grip of the present invention integrates the EMS function and the heating function, realizes the innovation and improvement of the conventional hand grip, can not only exercise the hand muscles through the elastic deformation part, but also promote the muscle recovery and force growth by means of electrical stimulation and thermotherapy methods. It has the advantages of diverse functions, easy to use, and remarkable effects.

[0028] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement within the technical scope disclosed by the present invention should be included within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the above claims.
