[0031] Currently, indoor sports have become another way for people to pursue health in their spare time from work and life. As a result, a large number of indoor sports fitness equipment have emerged, such as indoor exercise bikes, treadmills, and stair climbers, etc. The emergence and rise of these indoor sports fitness equipment have given people more choices for indoor sports and increased the types of sports that can be carried out indoors.

[0032] When people use indoor sports fitness equipment for exercise, a large amount of kinetic energy will be generated. For example, when using an indoor exercise bike for exercise, the pedaling action of the user will cause the sprocket of the indoor exercise bike to rotate, that is, the user's action will impart kinetic energy to the sprocket, causing the sprocket to rotate. To make full use of the kinetic energy on the sprocket, the present utility model proposes an energy storage device that can convert the kinetic energy generated by people during exercise into electrical energy and store it to make full use of the energy.

[0033] Refer to Figures 1 to 3 , specifically, the energy storage device proposed by the present utility model includes a generator set 1 and a battery 2. The generator set 1 is used to convert the kinetic energy generated by people into electrical energy, and the battery 2 is used to store the electrical energy generated by the generator 11. Among them, the energy storage device also includes an electronic control system 3 and a power-consuming component 4. The generator set 1 is electrically connected to the electronic control system 3, the electronic control system 3 is electrically connected to the battery 2, and the power-consuming component 4 is electrically connected to the electronic control system 3. The power-consuming component 4 is used to consume the electrical energy generated by the generator set 1 when the battery 2 is full.

[0034] Still taking the indoor exercise bike as an example, the indoor exercise bike has a bracket 100 and a sprocket 110 that mimics a bicycle. The bracket 100 provides support for the overall structure, and the sprocket 110 rotates due to the pedaling action of the user. The generator set 1 is connected to the sprocket 110. Thus, when the sprocket 110 rotates, the generator set 1 also rotates accordingly to generate electricity. That is, the setting of the generator set 1 converts the kinetic energy generated by the user during exercise into electrical energy. The battery 2 is used to store the electrical energy generated by the user driving the generator set 1 during exercise. Considering that the generator set 1 rotates with the rotation of the sprocket 110, that is, the angular velocity of the sprocket 110 during the user's exercise process is not constant. Therefore, the current generated by the generator set 1 is also unstable. The unstable current causes greater damage to the battery 2. To ensure the stability and durability of the battery 2, the electronic control system 3 rectifies the current generated by the generator set 1 to ensure the stability of the current and voltage, thereby reducing the probability of damage to the battery 2.

[0035] In addition, considering that if the battery 2 is still charged after being fully charged, it may cause damage to the battery 2. Therefore, the electronic control system 3 is also electrically connected to a power-consuming component 4. When the battery 2 is fully charged, if the generator set 1 is still generating current, the electronic control system 3 will conduct the current generated by the generator set 1 to the power-consuming component 4. The power-consuming component 4 has a very large resistance, and the current will be consumed after passing through the power-consuming component 4. That is, the power-consuming component 4 consumes the current generated by the generator set 1, thereby ensuring the integrity of the battery 2.

[0036] Refer to Figure 4 , specifically, the electronic control system 3 includes a first current detection element and a first voltage detection element. The first current detection element and the first voltage detection element are used to detect the current and voltage values generated by the generator set 1, so as to facilitate the electronic control system 3 to rectify the current generated by the generator set 1 to ensure the stability and durability of the battery 2. In addition, when the rotation speed of the generator set 1 is too low, that is, the values detected by the first current detection element and the first voltage detection element are too low and not conducive to charging the battery 2, this current can be directly led to the power-consuming component 4 and consumed. The electronic control system 3 also includes a second current detection element and a second voltage detection element. The second current detection element and the second voltage detection element are used to detect the current and voltage values of the battery 2 to supply the electronic control system 3 to control the charging state of the battery 2 and the flow direction of the current.

[0037] It should be noted that the above is illustrated by taking an indoor exercise bike as an example. In other fitness equipment, the above structure or method can also be used for conversion. For example, when using weightlifting equipment, the rotation of the weight component in the weightlifting equipment can drive the generator set 1 to rotate, thereby generating electricity. Without violating the above design concept, there are still many indoor fitness equipment that can generate electricity using the above structure, and the details are not elaborated in this utility model.

[0038] Referring to Figures 1 to 3 , specifically, in this utility model, the generator set 1 includes a generator 11 and a relay wheel 12. The relay wheel 12 includes a relay outer wheel 121 and a relay inner wheel 122, and the relay outer wheel 121 and the relay inner wheel 122 are coaxially arranged. Still taking the indoor exercise bike as an example, when the user pedals and makes the sprocket 110 rotate, the sprocket 110 will drive the relay outer wheel 121 to rotate, that is, the relay outer wheel 121 rotates with the movement of the person. Since the relay outer wheel 121 and the relay inner wheel 122 are coaxially arranged, when the relay outer wheel 121 rotates, the relay inner wheel 122 also rotates accordingly, and the relay inner wheel 122 will drive the generator set 1 to rotate, thereby completing power generation. In this utility model, the diameter of the relay outer wheel 121 is smaller than the diameter of the relay inner wheel 122, and the relay inner wheel 122 and the relay outer wheel 121 are coaxially arranged. Therefore, the relay inner wheel 122 and the relay outer wheel 121 have the same angular velocity, but the linear velocity of the relay inner wheel 122 will be greater than the linear velocity of the relay outer wheel 121. Compared with the situation where the diameter of the relay outer wheel 121 is equal to or greater than the diameter of the relay inner wheel 122, for each rotation of the sprocket 110, the generator 11 can generate more electric energy, that is, the energy conversion efficiency of the generator 11 is improved.

[0039] In addition, since the diameter of the relay outer wheel 121 is smaller than the diameter of the relay inner wheel 122, a greater resistance will be generated during the rotation of the sprocket 110, that is, the exercise bike itself will have a greater pedaling resistance, which can improve the exercise effect of the user.

[0040] Referring to Figures 1 to 3 , still taking the exercise bike as an example, in this utility model, the energy storage device further includes a bracket 100. The bracket 100 includes a bottom plate 120, a first support rod 130, a second support rod 140, and a third support rod 150. The first support rod 130, the second support rod 140, and the third support rod 150 are sequentially and spacedly arranged on the bottom plate 120. A first installation space 160 is formed between the first support rod 130 and the second support rod 140, and the electric control system 3 is arranged in the first installation space 160. A second installation space 170 is formed between the second support rod 140 and the third support rod 150, and the generator set 1 is arranged in the second installation space 170; and a support plate 180 is arranged between the second support rod 140 and the third support rod 150, and the support plate 180 is used to carry the generator set 1.

[0041] Reference Figures 1 to 3 In the above structure, the bottom plate 120 is used to provide support for the overall structure. The first support rod 130, the second support rod 140, and the third support rod 150 are actually used to provide support for the human body. The settings of the first installation space 160 and the second installation space 170 rationally utilize the overall space of the bracket 100, reduce the floor space occupied by the overall energy storage device, and ensure the miniaturized setting of the overall energy storage device in the present utility model.

[0042] Specifically, the power-consuming component 4 is arranged on the second support rod 140. The power-consuming component 4 includes a housing and a power-consuming resistor. The housing is fixedly arranged on the second support rod 140, and the power-consuming resistor is arranged inside the housing. The resistance of the power-consuming resistor is extremely large, and the excess electric energy generated by the generator set 1 can be converted into heat energy and consumed.

[0043] Reference Figure 1 and Figure 2 In the present utility model, when the user finishes exercising and the battery 2 has a certain amount of power, the battery 2 can be used to supply power to household appliances, digital devices, etc. Specifically, an electrical power supply interface and a digital device interface 135 are arranged on the bracket 100. Both the electrical power supply interface and the digital device interface 135 are electrically connected to the battery 2 and are used for externally outputting electric energy.

[0044] Reference Figure 2 and Figure 3 In the present utility model, the electrical power supply interface is arranged on the first support rod 130. The electrical power supply interface includes a socket 1311 and a three-pole plug 1312. The socket 1311 can supply power to ordinary household appliances, and the three-pole plug 1312 can supply power to high-power devices such as external large-capacity mobile power supplies. It should be noted that the height of the setting position of the electrical power supply interface on the first support rod 130 is relatively low. Considering that ordinary household appliances or large-capacity mobile power supplies generally have a large weight or volume and are not easy to move, if the setting position of the electrical power supply interface is relatively high, the wires may be suspended. The suspension of the wires is neither conducive to safety nor to human activities. Therefore, the electrical power supply interface is arranged at a relatively low position on the first support rod 130, so as to reduce the occurrence of the situation where the wires are suspended.

[0045] Reference Figure 3 and Figure 5, in addition, a rotating rod 132 is rotatably provided at the end of the first support rod 130 away from the bottom plate 120, and a handle 133 and a support frame 134 are provided at the end of the rotating rod 132 away from the bottom plate 120; among them, the handle 133 can provide support for the user when performing a pedaling action, and the support frame 134 can be used by the user to place digital devices such as mobile phones and tablets; it should be noted that, in order to reduce the volume of the overall structure when placed, the rotating rod 132 and the handle 133 can be rotatably provided, so that after the user finishes using, the rotating rod 132 and the handle 133 can be rotated and stored to reduce the volume of the overall structure, facilitating the user to store the overall structure after use.

[0046] Referring to Figure 3 and Figure 5 , considering that the user will place digital devices such as mobile phones and tablets on the support frame 134, the digital device interface 135 of the present utility model is provided on the support frame 134, so as to supply power to digital devices such as mobile phones and tablet lights; specifically, the digital device interface 135 is opened on one side of the support frame 134, and the digital device interface 135 includes at least one USB interface 1351 and at least one Type-C interface 1352. Both the USB interface 1351 and the Type-C interface 1352 are the mainstream interfaces of the charging cables of digital devices on the current market; the digital device interface 135 is used to supply power to digital devices; in addition, the user may have multiple digital devices. Therefore, in the present utility model, the support frame 134 is provided with two USB interfaces 1351 and one Type-C interface 1352.

[0047] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
