Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a hand gripper that is interactively controlled by a motor. Background Technology

[0002] Grip strengtheners, as a convenient fitness device, are widely used for hand muscle training and strength improvement. Traditional grip strengtheners have a simple structure, usually consisting only of elastic components and handles. They can only provide basic resistance training functions and cannot record and analyze key data such as the user's grip strength and number of repetitions. Users find it difficult to track their training progress and results, and they cannot be integrated with other fitness or rehabilitation equipment.

[0003] With the increasing penetration of intelligent technology in the fitness field, some smart hand grip strengtheners have begun to emerge, capable of detecting grip strength data. However, existing smart hand grip strengtheners still have many shortcomings: Firstly, most rely on battery power, requiring regular battery replacements, which not only increases operating costs but may also interrupt training due to battery depletion, resulting in poor usability. Secondly, their functions are relatively limited, mostly only capable of data detection and local storage, unable to integrate with other fitness or rehabilitation equipment (such as massage equipment). After completing grip strength training, users need to manually operate the massage equipment for relaxation, failing to achieve a seamless transition between training and relaxation. Furthermore, some smart hand grip strengtheners lack reliable counting functions, making it difficult to accurately count training repetitions, which is not conducive to users developing scientific training plans. Utility Model Content

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a trigger-type grip strength device with a reasonable structural design, which can accurately detect grip strength data, automatically count the number of training sessions, achieve self-sufficiency by using pneumatic power generation, and can be intelligently linked with external massage equipment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A grip strengthener controlled by an interactive motor includes a rubber sleeve, a bottom mold and a top mold elastically floating within the bottom mold, the bottom mold having a receiving cavity, the top mold elastically floating within the receiving cavity, an air inlet channel and an air outlet channel communicating with the receiving cavity respectively at the left and right ends of the bottom mold, an inner groove connecting to the receiving cavity within the bottom mold, and several guide grooves located at the outer edge of the inner groove within the bottom mold, the bottom of the top mold integrally connected to a guide post that slides with the guide grooves, a control PCB board on the inner groove, a pressure sensor on the control PCB board, a wireless transmission module on one side of the control PCB board on the pressure sensor, a counting module on the control PCB board on the other side of the control PCB board on the control PCB board, and a pneumatic generator on the control PCB board, the pneumatic generator being connected to the air outlet channel.

[0006] This utility model also includes a wireless receiving module connected to the wireless transmitting module. The wireless receiving module is installed on the external massage device, and the external massage device is equipped with an MCU control unit that is electrically connected to the wireless receiving module.

[0007] Furthermore, the rubber sleeve includes a sleeve body and a grip handle integrally connected to the sleeve body. Two thumb grooves are formed at one end of the sleeve body opposite the grip handle. An air inlet is formed on the sleeve body corresponding to the air inlet channel, and an air outlet is formed on the sleeve body corresponding to the air outlet channel. The design of the two thumb grooves accommodates the placement of both thumbs, improving comfort and stability during gripping. The air inlet and air outlet correspond to the air inlet and air outlet channels respectively, ensuring smooth airflow.

[0008] Furthermore, the grip handle is provided with four perforations. Each of the four perforations corresponds to one of the four fingers other than the thumb. Users can pass their fingers through the perforations to grip the gripper, effectively preventing the gripper from slipping during gripping, while also enhancing the fit between the hand and the grip handle, thus improving comfort during long training sessions.

[0009] Furthermore, an air intake rubber ring is provided in the air intake channel, and an air outlet rubber ring is provided in the air outlet channel. The air intake and air outlet rubber rings enhance the sealing performance of the air intake and air outlet channels, preventing airflow leakage within the channels. This ensures that when the top mold squeezes the cavity, the airflow can stably drive the pneumatic generator to generate electricity, while also ensuring that air can be quickly replenished during intake without affecting the normal reset of the gripper.

[0010] Furthermore, there are four guide grooves, which are arranged in a matrix at the four corners of the bottom surface of the cavity. A return spring is installed inside each guide groove, with both ends of the return spring elastically contacting the bottom of the guide post and the bottom of the guide groove. The cooperation of the guide grooves, guide posts, and return springs ensures that the top mold can move stably while also returning to its original position smoothly.

[0011] Furthermore, the top mold is equipped with an elastic pressure plate corresponding to the pressure sensor, and the top mold is provided with a receiving groove corresponding to the pneumatic generator. When the top mold moves to the bottom mold, the elastic pressure plate can form a uniform and stable contact with the pressure sensor, avoiding damage to the pressure sensor due to pressure concentration, and can also evenly transmit the gripping force on the top mold to the pressure sensor, improving the accuracy of gripping force detection. The receiving groove can accommodate the pneumatic generator to prevent the top mold from damaging the pneumatic generator when it moves to the bottom mold.

[0012] Furthermore, the total thickness of the control PCB board stacked with the wireless transmitting module or the counting module is not greater than the depth of the inner groove. The depth of the inner groove ensures that the control PCB board, the wireless transmitting module, and the counting module can be completely embedded in their respective grooves without protruding from the surface of the bottom mold, thus preventing damage to the control PCB board, the wireless transmitting module, and the counting module when the top mold presses down.

[0013] Furthermore, a storage battery is also installed on the control PCB board. The electrical energy generated by the pneumatic generator can be transmitted to the storage battery via wires for storage. The storage battery provides stable power support for electronic components such as the pressure sensor, wireless transmitter module, and counting module, enabling the grip strength device to be self-sufficient in power supply without the need to replace batteries, thus improving ease of use.

[0014] Compared with the prior art, the hand gripper controlled by the motor provided by this utility model has the following beneficial effects: This invention uses a pressure sensor to accurately detect grip strength data, and a counting module to automatically count training sessions. Users can monitor their training intensity and progress in real time, facilitating the development of scientific training plans. Simultaneously, the airflow generated during grip strength training drives a pneumatic generator to produce electricity, which is stored in a battery to power electronic components, achieving self-sufficiency and avoiding the inconvenience of frequent battery replacements, thus reducing operating costs. Through the cooperation of a wireless transmitting module, a wireless receiving module, and an MCU control unit, grip strength data and counting data can be transmitted to external massage equipment, enabling automatic adjustment of the massage mode. This allows users to enjoy a suitable massage and relaxation experience while completing training, enhancing the overall user experience.

[0015] This invention also features excellent stability. The four matrix-distributed guide grooves, in conjunction with the guide pillars, ensure stable movement of the top mold. The thumb groove in the rubber sleeve and the perforated design of the grip handle enhance grip stability and comfort, making it suitable for long-term training. The rubber rings in the air inlet and outlet channels enhance sealing and ensure power generation efficiency. Each electronic component is embedded in the inner groove to prevent collision damage and extend the lifespan of the grip strengthener. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] like Figures 1-6As shown, a gripper controlled by an interactive motor includes a rubber sleeve 1. A bottom mold 2 and a top mold 3 elastically floating within the bottom mold 2 are installed inside the rubber sleeve 1. A cavity 21 is formed on the bottom mold 2, and the top mold 3 elastically floats within the cavity 21. An air inlet channel 22 communicating with the cavity 21 is formed at the left end of the bottom mold 2, and an air outlet channel 23 communicating with the cavity 21 is formed at the right end of the bottom mold 2. An inner groove 211 connecting to the cavity 21 is formed inside the mold. Four guide grooves 212 are formed at the outer edge of the inner groove 211 inside the bottom mold 2, and the four guide grooves 212 are distributed in a matrix at the four corners of the bottom surface of the cavity 21. The top mold 3... The bottom is integrally formed with a guide post 31 that slides with the guide groove 212. A return spring 9 is installed in the guide groove 212. The two ends of the return spring 9 form elastic abutments with the bottom of the guide post 31 and the bottom of the guide groove 212, respectively, to ensure the stable pressing and stable reset of the top mold 3. The rubber sleeve 1 is sleeved on the outer surface of the bottom mold 2 and the top mold 3, and the connection between the rubber sleeve 1 and the bottom mold 2 and the top mold 3 is tightly fitted to ensure the airtightness between the bottom mold 2 and the top mold 3, thereby ensuring the airtightness of the cavity 21. When pressing, there will be no air leakage between the top mold 3, the bottom mold 2 and the rubber sleeve 1, which provides a guarantee for the continuous pressing operation. Specifically, a control PCB board 6 is installed on the inner tank 211. A pressure sensor 5 is installed on the control PCB board 6. A wireless transmitting module 7 is installed on one side of the pressure sensor 5 on the control PCB board 6, and a counting module 8 is installed on the other side of the pressure sensor 5 on the control PCB board 6. A pneumatic generator 4 is also installed on the control PCB board 6. The pneumatic generator 4 is connected to the air outlet channel 23. A storage battery 61 is also soldered onto the control PCB board. The storage battery 61 is a thin round battery. The storage battery 61 is electrically connected to the control PCB board. The pneumatic generator 4 is electrically connected to the storage battery 61. The pressure sensor 5, the wireless transmitting module 7, and the counting module 8 are all electrically connected to the control PCB board. The pneumatic generator 4 provides power to the storage battery 61, and the storage battery 61 provides power to the control PCB board 6, which in turn provides power to the pressure sensor 5, the wireless transmitting module 7, and the counting module 8. The rubber sleeve 1 includes a rubber sleeve body 11 and a grip handle 12 integrally formed with the rubber sleeve body 11. Two thumb grooves 111 are formed at one end of the rubber sleeve body 11 opposite to the grip handle 12. An air inlet 112 is formed on the rubber sleeve body 11 at the position corresponding to the air inlet channel 22, and an air outlet 113 is formed at the position corresponding to the air outlet channel 23. If necessary, the air inlet channel 22 is sealed through the inner wall of the air inlet 112, and the air outlet channel 23 is sealed through the inner wall of the air outlet 113, ensuring that the rubber sleeve body 11 tightly encloses the top mold 3 and the bottom mold 2, thereby ensuring stable air intake and exhaust through the air inlet channel 22 and the air outlet channel 23. The grip handle 12 has... Several perforations 121 provide a comfortable grip position for the user, effectively preventing the gripper from slipping during use and improving comfort during long-term training. An air intake rubber ring 221 is installed in the air intake channel 22, allowing air to enter but not exit. An air outlet rubber ring 231 is installed in the air outlet channel 23, allowing air to exit but not enter. An elastic pressure plate 32 is bonded to the top mold 3 at the position corresponding to the pressure sensor 5. The top mold 3 has a receiving groove 33 corresponding to the pneumatic generator 4, which can accommodate the pneumatic generator 4 and prevent damage to the pneumatic generator 4 when the top mold 3 is pressed down.

[0021] In this embodiment, the total thickness of the control PCB board 6 superimposed with the wireless transmitting module 7 or the counting module 8 is not greater than the depth of the inner groove 211, ensuring that all components (control PCB board 6, wireless transmitting module 7, and counting module 8) are completely embedded in the inner groove 211; the reset spring 9 is made of stainless steel, which has good elasticity and corrosion resistance; the elastic pressure plate 32 is made of hard rubber, which has a certain elastic deformation capability. When the user holds the gripper, the top mold 3 presses down, and the elastic pressure plate 32 contacts the pressure sensor 5 and applies pressure. The elastic pressure plate 32 can prevent the pressure sensor 5 from being directly subjected to rigid impact, extend the service life of the pressure sensor 5, and at the same time make the pressure transmission more uniform and improve the accuracy of pressure detection; the wireless transmitting module 7 and the wireless receiving module 100 use Bluetooth signal communication, which has stable transmission and low power consumption. In this embodiment, as Figure 7 As shown, it also includes a wireless receiving module 100 that is connected to the wireless transmitting module 7. The wireless receiving module 100 is installed on the external massage device 300. The external massage device 300 is equipped with an MCU control unit 200 that is electrically connected to the wireless receiving module 100. The wireless transmitting module 7 and the wireless receiving module 100 transmit data wirelessly.

[0022] When in use, the user places their thumbs on the thumb grooves 111 and their other fingers through the perforations 121 of the grip handle 12 to grip the gripper and apply grip force to train. During training, the grip force is automatically detected, the number of repetitions is counted, and power is generated. At the same time, the data is transmitted to the external massage device 300 to achieve intelligent linkage, thus realizing the experience of training and relaxation at the same time. After releasing the grip force, the top mold 3 automatically resets. The operation is convenient and the experience is good.
