[0037] In one embodiment of the present disclosure, referring to Figure 1 and Figure 2 , the shell 11 can be in a columnar shape, the shell 11 and the first grip arm 12 form a “T” shaped structure, and the second grip arm 13 is substantially parallel to the first grip arm 12. The number of the connecting parts 14 is two, the two connecting parts 14 are parallel, the extension direction of the connecting part 14 is cross and not coincident with the first direction X. The two ends of the connecting part 14 are respectively hinged with the shell 11 and the second grip arm 13, one end of the connecting part 14 away from the first grip arm 12 extends into the accommodating cavity and abuts against the elastic part 15, so that when the human hand exerts a gripping force on the second grip arm 13, the second grip arm 13 exerts a pressure on the elastic part 15 through the connecting part 14. Exemplarily, the end of the connecting part 14 away from the second grip arm 13 abutting against the elastic part 15 has a hook head abutting against the elastic part 15. In other embodiments of the present disclosure, the two ends of the connecting part 14 can be respectively hinged with the first grip arm 12 and the second grip arm 13.
[0038] Referring to Figure 2 , the elastic part 15 can include a spring 152 and a sliding block 151. The axis of the spring 152 extends along the first direction X, the spring 152 can be connected with the sliding block 151, the spring 152 is used to exert an action force on the sliding block 151 to slide towards the generator 2, the sliding block 151 can slide along the first direction X, and the side of the sliding block 151 away from the spring 152 abuts against the end of the connecting part 14 extending into the accommodating cavity. In other embodiments of the present disclosure, the elastic part 15 can also only include the spring 152.
[0039] The generator 2 can include a casing, a stator, a rotor and a fan. The casing can be in a columnar shape, the axis of the casing can be perpendicular to the axis of the shell 11, and the stator, the rotor and the fan are arranged in the casing. The number of the stators is two, the two stators are opposite permanent magnets, the polarities of the two stators are opposite to form a magnetic field, and the two stators are fixed in the casing and have a gap therebetween. The rotor is coaxially arranged in the casing and located in the gap between the two stators, the rotor is a coil structure and can rotate in the gap between the two stators to cut the magnetic induction lines to generate current.
[0040] In the embodiment of the present disclosure, the structure of the connecting assembly 3 has two kinds.
[0041] Referring to Figure 1 and Figure 2, the first connecting assembly 3 comprises a gear 31 and a rack 32, the rack 32 extends along the first direction X and is engaged with the gear 31, the rack 32 is fixedly connected with the end of the sliding block 151 away from the spring 152, and the gear 31 is fixedly connected with the rotor and coaxially arranged. In this way, when the human hand tightly holds the handgrip, the second gripping arm 13 rotates towards the first gripping arm 12, the connecting part 14 exerts pressure on the sliding block 151 along the first direction X, the sliding block 151 drives the rack 32 to move away from the generator 2, so that the spring 152 is compressed, the rack 32 drives the gear 31 to rotate, and thus the gear 31 drives the rotor to rotate to generate current, thereby converting mechanical energy into electrical energy. When the human hand releases the handgrip, the spring 152 pushes the sliding block 151 to move close to the generator 2 due to the removal of the pressure exerted on the sliding block 151, the sliding block 151 drives the rack 32 to move synchronously, so that the gear 31 rotates, and the gear 31 drives the rotor to rotate to generate current. Alternatively, when the human hand releases the handgrip, the spring 152 pushes the sliding block 151 to move close to the generator 2 due to the removal of the pressure exerted on the sliding block 151, the sliding block 151 drives the rack 32 to move synchronously, so that the gear 31 rotates, and the gear 31 does not drive the rotor to rotate, thereby not generating current when the handgrip is released.
[0042] Referring to Figure 1 and Figure 3 , the second connecting assembly 3 comprises a rotating disc 33 and a connecting rod 34. The rotating disc 33 is fixedly connected with the rotor coaxially, one end of the connecting rod 34 is rotationally connected with the rotating disc 33 and eccentrically arranged, and the other end is hingedly connected with the end of the sliding block 151 away from the spring 152. In this way, when the human hand tightly holds the handgrip, the second gripping arm 13 rotates towards the first gripping arm 12, the connecting part 14 exerts pressure on the sliding block 151 along the first direction X, the sliding block 151 drives the connecting rod 34 to move away from the generator 2, so that the spring 152 is compressed, the connecting rod 34 drives the rotating disc 33 to rotate, and thus the rotating disc 33 drives the rotor to rotate to generate current, thereby converting mechanical energy into electrical energy. When the human hand releases the handgrip, the spring 152 pushes the sliding block 151 to move close to the generator 2 due to the removal of the pressure exerted on the sliding block 151, the sliding block 151 drives the connecting rod 34 to move, so that the rotating disc 33 continuously rotates, and the rotating disc 33 drives the rotor to rotate to continuously generate current.
[0043] In an embodiment of the present disclosure, in order to drive the sliding block 151 to move along the first direction X, the inner bottom wall of the shell 11 is provided with a sliding groove extending along the first direction X, and the sliding block 151 is slidingly connected in the sliding groove and cannot be separated from the sliding groove, so as to facilitate the sliding block 151 to drive the rotor to rotate during movement.
[0044] In an embodiment of the present disclosure, referring to Figure 1The first arm 12 has a placing cavity which is in communication with the accommodating cavity. The handgrip further comprises a battery 4 which is arranged in the placing cavity and is used to store the electric energy generated by the generator 2. In this way, the electric energy generated by the generator 2 can be stored in the battery 4, and the battery 4 can be used to supply power to electronic devices, such as a mobile phone, a table lamp, a radio and the like.
[0045] In an embodiment of the present disclosure, the capacity of the battery 4 can be 500-1000 mAh. For example, the capacity of the battery 4 can be 500 mAh, 600 mAh, 800 mAh, 1000 mAh or the like.
[0046] In an embodiment of the present disclosure, referring to Figure 1 The handgrip further comprises a control assembly 5. The control assembly 5 comprises a counting unit, a force measuring unit and a communication unit.
[0047] The counting unit is arranged in the placing cavity and is used to count the number of training, so as to count the number of handgrip. The force measuring unit is arranged in the placing cavity and is used to measure the handgrip, so as to provide training information for the user. The communication unit is arranged in the placing cavity and is used to interact with the mobile phone. For example, the communication unit can be wirelessly connected with the mobile phone through Bluetooth, a local area network or the like, or can be connected with the mobile phone through a USB interface. In this way, the user can monitor the exercise data in real time through the mobile phone, which is beneficial to the health training of the user. The exercise data can be the number of handgrip and the number of calories consumed.
[0048] In an embodiment of the present disclosure, referring to Figure 1 The control assembly 5 further comprises a charging and discharging management unit. The charging and discharging management unit is arranged in the placing cavity and is electrically connected with the generator 2 and the battery 4, respectively, and is used to control the charging and discharging of the battery 4. The first arm 12 is provided with a charging port 6 which is electrically connected with the charging and discharging management unit. In this way, the charging and discharging of the battery 4 can be controlled through the charging and discharging management unit, and the battery 4 can be used to charge the electronic devices through the charging port 6, so as to be prepared for the emergency.
[0049] In an embodiment of the present disclosure, the control assembly 5 further comprises an adjusting unit. The adjusting unit is arranged in the placing cavity and is used to control the rotating speed of the rotor and the charging power of the battery 4. For example, the handgrip has a grip gear, and the size of the grip gear affects the intensity of the hand training, and the grip gear is matched with the rotating speed of the rotor. In an example, the grip gear can be divided into three gears, and the rotor corresponds to three rotating speeds. One gear of the grip gear corresponds to one rotating speed of the rotor. When the grip gear of the handgrip needs to be adjusted, the adjusting unit sends an adjusting signal to the generator 2, and the generator 2 adjusts the rotating speed of the rotor in response to the adjusting signal, so as to switch to the grip gear corresponding to the rotating speed, and adapt to the training of users with different arm strength.
[0050] For example, the rotation speed of the rotor directly affects the charging power of the battery 4, and the rotation speed of the rotor is different, the power generated by the generator 2 is also different, so the charging of the battery 4 is also different. When the grip level of the handgrip needs to be adjusted, the adjustment unit will control the charging power of the battery 4, so as to change the rotation speed of the rotor of the generator 2, so as to switch to the grip level corresponding to the rotation speed, and realize the adjustment of the grip level of the handgrip.
[0051] In an embodiment of the present disclosure, referring to Figure 1 The shell 11 is provided with a display panel 7. The display panel 7 can be a liquid crystal panel, an LED panel, an OLED panel, etc. The real panel can display the data that can be monitored, such as time, frequency, training time, energy consumption, power generation, battery 4 power, etc.
[0052] Next, the working principle of the embodiment of the present disclosure will be described.
[0053] When the human hand holds the handgrip, the second grip arm 13 will rotate towards the first grip arm 12, the connecting part 14 will exert a pressure on the sliding block 151 in the first direction X, the sliding block 151 will make the spring 152 compressed, and the connecting assembly 3 will drive the rotor to rotate, and the current generated by the rotor will be stored in the battery 4 through the charge and discharge management unit.
[0054] When the human hand releases the handgrip, the pressure applied to the sliding block 151 is removed, the spring 152 will push the sliding block 151 to move close to the generator 2, the sliding block 151 will drive the rotor to rotate through the connecting assembly 3, and the current generated by the rotor will be stored in the battery 4 through the charge and discharge management unit.
[0055] When the battery 4 needs to be discharged, the charge and discharge management unit will control the electric energy in the battery 4 to supply power to other electronic devices through the charging port 6, which reduces the waste of energy, improves the utilization rate of energy, and increases the function of the handgrip.
[0056] Other embodiments of the present disclosure will be readily apparent to those skilled in the art upon considering the specification and practice of the disclosed application. The present application is intended to cover any variations, uses, or adaptations of the present disclosure that follow, in general, the principles of the present disclosure and include those that are known or customary practice in the art to which the present disclosure pertains.
