[0031] At present, some fitness equipment can convert mechanical energy into electrical energy while exercising, and realize synchronous power generation during exercise. The electricity generated by the fitness equipment is generally stored in the battery inside the fitness equipment, and then powered by external devices. However, fitness equipment is not easy to move and carry, resulting in its inability to be portable.

[0032] In view of this, the utility model proposes a motion energy storage device.

[0033] See also Figure 1 and Figure 3 In one embodiment of the utility model, the motion energy storage device includes a bracket 1, a power generation module, a circuit board 4 and a battery 5, and a charging socket 121 is installed on the bracket 1; the power generation module includes a flywheel assembly 2 and a generator 3 that are transmission-connected, and the flywheel assembly 2 is installed on the bracket 1, and the flywheel assembly 2 is used to drive the generator 3 to generate electricity; the circuit board 4 is electrically connected to the generator 3 and the charging socket 121, respectively, and a controller and a first electronic switch are provided on the circuit board 4; the battery 5 is electrically connected to the circuit board 4, and the first electronic switch is used to control the conduction and disconnection of the circuit between the circuit board 4 and the battery 5; wherein, when the charging socket 121 is connected to an external power supply to be charged, the first electronic switch is turned off.

[0034] Specifically, the bracket 1 is a basic supporting structure of the motion energy storage device, which is used to support the user and install other components of the motion energy storage device. In this embodiment, the bracket 1 is also used to fix the flywheel assembly 2. In order to better install the components and play the function of supporting the user, the bracket 1 is generally set to a metal material. The bracket 1 can be made of iron or steel, which is not specifically limited here.

[0035] The power generation module of the utility model is used to realize the power generation function, mainly including a generator 3 and a flywheel assembly 2. The flywheel assembly 2 is rotatably connected to the bracket 1, so the flywheel assembly 2 can rotate relative to the bracket 1. The flywheel assembly 2 can rotate relative to the bracket 1 by providing a driving force by the user, wherein the user can provide the driving force through a pulling device or a thrust device, or the user can provide the driving force through a pedal device. The flywheel assembly 2 can be provided with a single rotatable wheel body, or multiple rotatable wheel bodies can be provided, and the multiple rotatable wheel bodies can rotate separately or synchronously, which is not specifically limited here.

[0036] The flywheel assembly 2 is connected to the generator 3 in a transmission manner, and can generate electricity by driving the flywheel assembly 2 to rotate and then drive the generator 3 to rotate and cut the magnetic flux lines, wherein the electricity generated by the power generation module can be used for the fitness equipment 100 using the motion energy storage device, and the additional electricity generated by the generator 3 will be delivered to the battery 5 in the motion energy storage device. In addition, a charging socket 121 is also provided on the bracket 1, and the socket is used to transmit the electricity generated by the generator 3 to an external power supply electrically connected to the charging socket 121, so the electricity generated by the power generation module can also be used for the external power supply electrically connected to the charging socket 121, and the external power supply is a rechargeable battery 5. Among them, when an external power supply is connected to the motion energy storage device, the power generation module can give priority to charging the battery 5, or it can give priority to charging the external power supply, which is not specifically limited here.

[0037] More specifically, the motion energy storage device is provided with a circuit board 4, which is electrically connected to the generator 3, the charging socket 121 and the battery 5, respectively, so that the electricity generated by the generator 3 is first converted into AC electricity by the circuit board 4, and then transmitted to the battery 5 and / or the generator 3. Among them, a controller is provided on the circuit board 4 to issue instructions to the electronic devices on the circuit board 4, and a first electronic switch is provided on the circuit board 4, and the conduction and closing of the circuit between the circuit board 4 and the battery 5 are controlled by the first electronic switch. When the charging socket 121 is connected to an external power supply to be charged, the first electronic switch is turned off to stop the circuit board 4 from transmitting current to the battery 5, and only charge the external power supply, thereby ensuring that the external power supply has priority in charging. The controller can be an electronic chip, and the first electronic switch can be a MOSFET (metal oxide semiconductor field effect transistor) or an IGBT (insulated gate bipolar transistor).

[0038] The technical solution of the utility model adopts a charging socket 121 electrically connected to the generator 3 provided in the motion energy storage device, so that the electricity generated by the generator 3 can be transmitted to the battery 5 in the motion energy storage device, and can also be transmitted to the external power supply through the charging socket 121, thereby realizing a portable power supply function through the external power supply, thereby meeting the user's usage needs.

[0039] In one embodiment, please continue to refer to Figure 1 and Figure 3 A second electronic switch is provided on the circuit board 4, and the second electronic switch is used to control the conduction and disconnection between the circuit board 4 and the charging socket 121. When the external power supply connected to the charging socket 121 is fully charged, the second electronic switch is turned off, and the controller controls the first electronic switch to be turned on.

[0040] Specifically, according to the above-mentioned embodiment, a controller is provided on the circuit board 4, and the controller issues instructions to control the on and off of the second electronic switch. When the external power supply to be charged is connected to the charging socket 121, the second electronic switch remains on, and the current flowing through the circuit board 4 is transmitted to the inside of the external power supply through the charging socket 121. When the external power supply is fully charged, the controller issues an instruction to the second electronic switch to turn off the second electronic switch, and issues an instruction to the first electronic switch to turn on the second electronic switch, thereby continuing to charge the battery 5. The second electronic switch can be a MOSFET (metal oxide semiconductor field effect transistor) or an IGBT (insulated gate bipolar transistor).

[0041] It should be noted that, in the above-mentioned embodiment, it has been explained that the electricity generated by the power generation module can be used to be transmitted to the battery 5, and the electricity generated by the power generation module can also be used to be transmitted to the external power supply through the charging socket 121. In this embodiment, when the charging socket 121 is connected to an external power supply, the current generated by the power generation module has a priority in the transmission target. The power generation module will give priority to transmitting the generated current to the external power supply, and will only transmit it to the battery 5 when the external power supply no longer receives current, thereby meeting the user's usage needs.

[0042] In one embodiment, see Figure 3 A high-voltage inverter device is provided on the circuit board 4, and the circuit board 4 is electrically connected to the charging socket 121. The high-voltage inverter device is used to convert the direct current output by the generator 3 into alternating current.

[0043] It should be noted that, considering that the electricity generated by driving the flywheel assembly 2 to drive the generator 3 to cut the magnetic inductance is direct current, and the external power supply generally needs to be connected to an alternating current power supply before it can be used, a high-voltage inverter is provided on the circuit board 4, and the direct current generated by the generator 3 is converted into alternating current through the high-voltage inverter, so as to power the external power supply and the battery 5. The reason why the current inverter adopts a high-voltage inverter is that the high-voltage system can transmit electricity more efficiently and reduce line losses. The high-voltage inverter is installed on the circuit board 4 and is located Figure 3 The inside of the housing 41 of the connecting circuit board 4.

[0044] In one embodiment, see Figure 1 and Figure 2 The flywheel assembly 2 includes a driving wheel 21 and a driven wheel 22, the driving wheel 21 and the driven wheel 22 are respectively rotatably connected to the bracket 1, the driving wheel 21 and the driven wheel 22 are transmission connected, and the generator 3 is transmission connected to the driven wheel 22.

[0045] Specifically, the flywheel assembly 2 includes a driving wheel 21 and a driven wheel 22 which are connected in a transmission manner, wherein the driving wheel 21 and the driven wheel 22 are respectively connected in rotation to the bracket 1, so the driving wheel 21 and the driven wheel 22 can rotate relative to the bracket 1. In this embodiment, the driven wheel 22 is driven to rotate by driving the driving wheel 21, and in other embodiments, the driven wheel 22 can also be driven to drive the driving wheel 21 to rotate. The transmission method can be belt tooth transmission, chain transmission, or gear meshing transmission, and the transmission method of the driving wheel 21 and the driven wheel 22 can be any one of the above transmission methods.

[0046] In one embodiment, see Figure 1 The bracket 1 includes a mounting base plate 11, a first support column 12, a second support column 13 and a third support column 14, and the first support column 12, the second support column 13 and the third support column 14 are arranged on the mounting base plate 11 at intervals.

[0047] Specifically, in this embodiment, the bracket 1 includes at least a mounting base 11, a first support 12, a second support 13 and a third support 14, wherein the first support 12 is used to directly or indirectly mount a screen bracket and a handle of the fitness equipment 100, the second support 13 is used to make the overall structure of the bracket 1 more stable, and the third support 14 is used to mount a seat bag.

[0048] In one embodiment, see Figure 1 An installation space 15 is formed between the first pillar 12 and the second pillar 13 , and the circuit board 4 is installed on the installation base plate 11 and is located in the installation space 15 .

[0049] Specifically, an installation space 15 is formed between the first pillar 12 and the second pillar 13. The circuit board 4 is installed in the installation space 15 to make full use of the space. The circuit board 4 is installed on the base plate. Considering that the area of ​​the circuit board 4 in this embodiment is too large, laying it flat on the base plate will cause the width of the fitness equipment 100 to be too large, so the circuit board 4 is vertically installed on the installation base plate 11.

[0050] In one embodiment, see Figure 1The bracket 1 further includes a cross beam 16 , and the cross beam 16 is respectively mounted on the second pillar 13 and the third pillar 14 , the generator 3 is mounted on the cross beam 16 , and the generator 3 is spaced apart from the mounting base plate 11 .

[0051] It should be noted that, in consideration of facilitating the installation of the generator 3, a crossbeam 16 is provided which connects the second support 13 and the third support 14 respectively, and the generator 3 is installed on the crossbeam 16. Specifically, the generator 3 is installed on one side of the crossbeam 16. In order to prevent the generator 3 from being affected during rotation, the generator 3 is spaced apart from the mounting base plate 11.

[0052] In one embodiment, see Figure 1 and Figure 3 The battery 5 is installed on the mounting base plate 11 , and the generator 3 is located between the battery 5 and the circuit board 4 .

[0053] Specifically, the battery 5 is mounted on the mounting base plate 11, and the generator 3 is located between the battery 5 and the circuit board 4. Considering the spatial distribution on the mounting base plate 11, the circuit board 4 is mounted in the mounting space 15 of the first pillar 12 and the second pillar 13, and the generator 3 is mounted between the second pillar 13 and the third pillar 14. Therefore, the generator 3 is mounted on the outside of the third pillar 14, that is, the generator 3 is located on the side of the third pillar 14 away from the generator 3. In this way, the mounting space 15 of the mounting base plate 11 in its length direction is fully utilized, so that the various components of the motion energy storage device are arranged more compactly, and the space occupied by the fitness equipment 100 with the motion energy storage device is reduced.

[0054] In one embodiment, see Figure 2 The flywheel assembly 2 also includes a pedal assembly 23, which includes a crank 231 and a pedal 232. One end of the crank 231 is connected to the middle of the driving wheel 21, and the other end of the crank 231 is connected to the pedal 232. The pedal 232 drives the driving wheel 21 to rotate along the circumference of the driving wheel 21.

[0055] Specifically, further, when the fitness equipment 100 is configured as a spinning bike, the driving device of the flywheel assembly 2 is a pedal assembly 23, wherein the pedal assembly 23 is arranged in pairs, and the pedal assembly 23 includes a crank 231 and a pedal 232 connected to each other, and the crank 231 and the pedal 232 can be connected in rotation or fixedly connected. The pedal assembly 23 in this embodiment is arranged in pairs, so a pair of pedal assemblies 23 includes two cranks 231 and two pedals 232, and the two sets of cranks 231 and pedals 232 are respectively arranged on opposite sides of the driving wheel 21. Specifically, in this embodiment, the crank 231 and the pedal 232 are connected in rotation through a rotating shaft. The user of the fitness equipment 100 can drive the crank 231 to rotate by applying a driving force to the pedal 232. Considering that the crank 231 is fixedly connected to the driving wheel 21, the driving wheel 21 and the crank 231 can be driven to rotate together.

[0056] In one embodiment, see Figure 3 and Figure 4 The charging socket 121 is configured as a three-pole socket.

[0057] Specifically, the charging socket 121 is configured as a three-pole socket. This type of charging socket 121 has three poles, which are used to abut against the spring pieces of the external power supply interface electrically connected to it, thereby realizing the electrical connection between the external power supply and the charging socket 121. This three-pole socket is specifically used to charge a rechargeable external power supply that is compatible with it.

[0058] The present utility model further proposes a fitness equipment 100, which includes a motion energy storage device.
