[0032] Embodiment

[0033] As Figures 1 - 5 As shown, a preferred embodiment of an electronic grip strength exerciser provided by the present invention includes a grip ring portion 2, an elastic bracket 1, and an electronic function portion 3; both ends of the elastic bracket 1 are respectively connected to the grip ring portion 2; the electronic function portion 3 is connected to the elastic bracket 1; the electronic function portion 3 includes a sensing module 34, a power supply module 33, a control module 32, and a display screen module 31. The power supply module 33 is adapted to supply power to the remaining modules. The sensing module 34 and the display screen module 31 are respectively electrically connected to the control module 32; the sensing module 34 includes a counting sensing unit and / or a pressure sensing unit.

[0034] The grip ring part 2 and the elastic support 1 are jointly used to stretch the user's palm. The elastic force required for the grip force can be provided solely by the elastic support 1, or part or all of the grip ring part 2 can be made of an elastic material to jointly provide the elastic force with the elastic support 1. Preferably, the grip ring part 2 is integrally circular, and the elastic support 1 is arranged at the hollow position in the middle of the ring, and its two ends are respectively connected to the grip ring part 2.

[0035] The elastic support 1 includes a first support 11, a second support 12 slidably connected to the first support 11, and an elastic member 5 provided between the first support 11 and the second support 12. The ends of the first support 11 and the second support 12 away from each other are respectively connected to the grip ring part 2.

[0036] In this embodiment, the grip ring part 2 includes a first half-ring 21 and a second half-ring 22, and the first half-ring 21 and the second half-ring 22 are spaced apart. The first support 11 is connected to the first half-ring 21, and the second support 12 is connected to the second half-ring 22. The elastic member 5 is preferably a compression spring.

[0037] A receiving cavity 111 is provided in the first support 11. One end of the second support 12 is slidably connected to the receiving cavity 111, and the elastic member 5 is located in the receiving cavity 111. When a finger exerts force to squeeze the grip ring part 2, the end of the second support 12 close to the first support 11 can slide deeper into the receiving cavity 111. Preferably, the end of the second support 12 close to the first support 11 is always located within the opening of the receiving cavity 111.

[0038] An installation part is provided in the first support 11, which is suitable for accommodating and installing the electronic function part 3. In this embodiment, a cylindrical installation part is preset at the end of the first support 11 close to the second support 12. The inside of the installation part is hollow and has an installation cavity. The above-mentioned receiving cavity 111 passes through the installation part. Preferably, the installation cavity is not communicated with the receiving cavity 111 to ensure the smoothness of the sliding between the second support 12 and the first support 11. At the same time, the sealing degree of the installation cavity can be further improved to protect the electronic function part 3 located inside the installation cavity.

[0039] The counting induction unit can adopt a counting switch or a Hall induction unit, and is installed at the end of the receiving cavity 111 away from the second support 12. When the second support 12 approaches the first support 11 to a certain distance, the counting switch or the Hall induction unit is triggered, and the control module 32 reads the signal of the counting induction unit and issues an instruction to increase the number of practice times displayed on the display screen module 31 by one.

[0040] The pressure sensing unit can be arranged at the opening end or the bottom end of the accommodating cavity 111, between the elastic member 5 and the first bracket 11 or the second bracket 12; the control module 32 reads the signal of the pressure sensing unit and issues an instruction to display the current grip strength value on the display screen module 31. In some embodiments, the timing sensing unit and the sensing unit can be integrally arranged. Specifically, in the program built in the control module 32, script codes for comparing pressure values can be added. When the change in the pressure value transmitted by the pressure sensing unit exceeds a specific preset value, the count is incremented by one, thereby simplifying the circuit structure.

[0041] In this embodiment, the electronic function unit 3 includes a sensing module 34, a power supply module 33, a control module 32, and a display screen module 31. The sensing module 34 preferably includes a counting sensing unit and a pressure sensing unit. The power supply module 33 is electrically connected to the control module 32. The control module 32 includes a microchip and a function key. The display screen module 31 is electrically connected to the control module 32. Preferably, the power supply module 33, the control module 32, and the display screen module 31 are arranged on the same circuit board. The counting sensing unit and the pressure sensing unit are respectively electrically connected to the control module 32.

[0042] Furthermore, an adjusting assembly 4 is further included, which is respectively connected to the first bracket 11 and the second bracket 12 and is adapted to adjust the minimum grip strength value so as to match the needs of the user for different grip strength exercises.

[0043] The adjusting assembly 4 includes an adjusting member 41, which is slidably and rotatably connected to the first bracket 11; an adjusting part 42, which is arranged on the second bracket 12. The adjusting member 41 passes through the first bracket 11 and is connected to the adjusting part 42. By operating the adjusting member 41, the second bracket 12 is driven, thereby adjusting the relative position between the first bracket 11 and the second bracket 12. A first locking part is provided on the first bracket 11, and a second locking part is provided on the adjusting member 41. Cooperating with the first locking part, it is adapted to limit the rotation of the adjusting member 41.

[0044] Specifically, the adjusting member 41 includes a knob 411 and a gear part 413 connected to the knob 411 through a shaft rod 412; the adjusting part 42 has a plurality of adjusting teeth 421, which are distributed along the length direction of the second bracket 12. The shaft rod 412 is slidably inserted into the first bracket 11, and the knob 411 and the gear part 413 are respectively fixed at both ends. The gear part 413 meshes with the adjusting part 42. Thus, by screwing the knob 411, the adjusting part 42 is driven, so that the second bracket 12 moves towards or away from the first bracket 11, changing the maximum stroke of the elastic member 5, achieving the purpose of adjusting the minimum grip strength value.

[0045] Further, an opening groove 121 is provided at one end of the second bracket 12 close to the first bracket 11, and an installation groove 122 is provided in the opening groove 121; the adjusting part 42 includes an installation frame 423 fixedly connected to the installation groove 122; the installation frame 423 has a strip-shaped through hole 422, and an adjusting tooth 421 is arranged on the hole wall of the strip-shaped through hole 422, and the strip-shaped through hole 422 communicates with the opening groove 121.

[0046] The first locking part is a positioning groove, and the second locking part is a positioning block. Through the insertion fit of the positioning block and the positioning groove, the rotation limit of the rotary cap 411 is realized, so as to lock the relative position between the first bracket 11 and the second bracket 12.

[0047] The positioning block is located on one side of the first bracket 11 close to the adjusting member 41, and the positioning groove is located on one side of the rotary cap 411 or the shaft rod 412 close to the first bracket 11. For example, the positioning block is a square column protruding from one side of the first bracket 11 close to the rotary cap 411. The shaft rod 412 is arranged on the central axis of the positioning block. The positioning groove is a square columnar groove arranged on the rotary cap 411, and the shape is adapted to the positioning block. When the minimum grip force value needs to be adjusted, pull the rotary cap 411 outwards to disengage the positioning block from the positioning groove and unlock it. Then, the rotary cap 411 can be rotated to adjust the relative position between the first bracket 11 and the second bracket 12. In some other embodiments, the positioning groove is arranged in the shaft hole for the shaft rod 412 to pass through on the first bracket 11, and the positioning block is arranged on the shaft rod 412 and has a toothed structure. In still some other embodiments, the positioning block can be arranged on the inner wall of the accommodation cavity 111 far from the rotary cap 411, and the positioning groove is arranged at one end of the gear part 413 far from the rotary cap 411.

[0048] Further, a reset member is further included, which is respectively connected to the adjusting member 41 and the first bracket 11 and is adapted to keep the first locking part and the second locking part in a locked state. For example, the reset member is a spring arranged between the gear and the first bracket 11. At the shaft hole on the side of the first bracket 11 close to the rotary cap 411 where the shaft rod 412 passes through, a positioning block is arranged on the inner wall of the corresponding accommodation cavity 111, and the positioning groove is arranged on the shaft rod 412. The gear part 413 is pressed by the elastic force of the spring, and the shaft rod 412 connected to the gear part 413 then has an outward potential energy, pushing the positioning groove on the shaft rod 412 towards the positioning block, thereby locking the first locking part and the second locking part. When adjustment is needed, apply an external force to press the rotary cap 411, overcome the pressure of the reset member, and the rotary cap 411 drives the shaft rod 412 to move towards the first bracket 11, separating the positioning block from the positioning groove, and then the locking can be released. Then, the rotary cap 411 can be rotated for adjustment.

[0049] The grip ring portion 2 includes a first half-ring 21 and a second half-ring 22. The first half-ring 21 and the second half-ring 22 are spaced apart, that is, there is a certain distance between the first half-ring 21 and the second half-ring 22; the first bracket 11 is connected to the first half-ring 21, and the second bracket 12 is connected to the second half-ring 22. Preferably, both the first half-ring 21 and the second half-ring 22 are arc-shaped, and the corresponding central angle is between 90° and 180°. In this embodiment, it is 165°, and the first half-ring 21 and the second half-ring 22 are mirror-symmetrically distributed.

[0050] Furthermore, a number of recessed finger-positioning portions 23 are provided on the first half-ring 21 or the second half-ring 22 to help the user locate the position of the fingers during training.

[0051] An electronic grip strength trainer of the present utility model displays the number of grip exercises and / or the current grip strength value on the display screen module of the electronic functional portion by arranging the electronic functional portion on the elastic bracket, enabling the user to understand the real-time training situation, further control the implementation of the training plan, and improve the training efficiency.

[0052] The above embodiments only represent some implementation manners of the present invention. Without departing from the inventive concept of the present invention, those skilled in the art have made several deformations, substitutions, and improvements without creative labor, and these all fall within the protection scope of the present invention.
