[0039] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. In addition, the technical features involved in the different embodiments of the present application described below may be combined with each other as long as they do not conflict with each other.

[0040] In a first aspect, the present application embodiment provides an energy storage device 100, please refer to Figures 1 to 3 The energy storage device 100 includes a control panel 10, a key assembly 20 and a circuit board 30, wherein the key assembly 20 is disposed between the control panel 10 and the circuit board 30. Figure 4 The control panel 10 is provided with a first mounting hole 11, and the button assembly 20 is disposed in the first mounting hole 11. Please refer to Figure 5 The circuit board 30 has a switch 31, and the switch 31 is arranged facing the key assembly 20. By pressing the key assembly 20, the connection and disconnection between the pressing assembly and the switch 31 can be achieved, so as to achieve the purpose of opening or regulating the energy storage device 100.

[0041] For the above-mentioned key assembly 20, please refer to Figure 6 and Figure 7 The key assembly 20 includes a first pressing member 21, an elastic supporting member 22 and a contact member 23. The first pressing member 21 is connected to the elastic supporting member 22 and the contact member 23 respectively, and the contact member 23 can be in contact with or disconnected from the switch 31 to achieve the purpose of regulating the energy storage device 100.

[0042] For the first pressing member 21, please refer to Figure 6 and Figure 7 The first pressing piece 21 partially extends out of the first mounting hole 11, and the first pressing piece 21 extending out of the first pressing hole is used for convenience of users to press.

[0043] For the elastic support member 22, please refer to Figure 6 and Figure 7 The elastic support member 22 can provide elastic force under the action of external force, and when the external force is removed, the elastic support member 22 can return to its original shape and position. The elastic support member 22 can be made of elastic material, such as rubber, silicone, polypropylene, polyurethane, etc. Figure 8 and Fig. 9 The elastic support member 22 is connected to the first pressing member 21. The elastic support member 22 is supported between the first pressing member 21 and the circuit board 30. When the first pressing member 21 is pressed, the elastic support member 22 can generate an elastic force. After the external force is removed, the elastic support member 22 can drive the first pressing member 21 to return to its original position. Furthermore, the elastic support member 22 and the first pressing member 21 jointly enclose an installation space 24, and the switch 31 is arranged facing the space, so that the elastic component is conveniently connected to the switch 31.

[0044] For the above-mentioned contact 23, please refer to Figures 7 to 9 The contact member 23 is a component used to abut against the switch 31 to achieve the purpose of connecting the button assembly 20 and the switch 31 to control the energy storage device 100. The contact member 23 is arranged in the installation space 24, and the elastic support member 22 and the first pressing member 21 surround the contact member 23 inside, which can reduce the damage to the contact member 23 by moisture, dust and impurities. One end of the contact member 23 is connected to the first pressing member 21, and a first space 241 is provided between the other end of the contact member 23 and the switch 31 for the contact member 23 to be compressed when the contact member 23 is pressed. When the first pressing member 21 is pressed, the contact member 23 is constructed to abut against the switch 31. When the pressing is cancelled, the contact member 23 returns to its original position, and the contact member 23 is disconnected from the switch 31.

[0045] Please refer to Figures 7 to 9, wherein the first abutting member 12 is disposed around the inner wall of the first mounting hole 11, the first pressing member 21 has a first limiting member 211, and a second space 131 is provided between the first limiting member 211 and the first abutting member 12 for being compressed when the key assembly 20 is pressed. When the first pressing member 21 is pressed, the second space 131 is compressed, and the first abutting member 12 is configured to abut against the first limiting member 211. After the first limiting member 211 abuts against the first abutting member 12, the first pressing member 21 is restricted from moving toward the circuit board 30, thereby reducing the problem of the key assembly 20 being pressed and collapsed and causing the key assembly 20 to fail. Moreover, in the process of pressing the first pressing member 21, the elastic supporting member 22 can shrink and stretch in the second space 131, thereby ensuring that the elastic supporting member 22 is deformed within a controllable range, thereby reducing the pressure of the first pressing member 21 and the contact member 23 on the switch 31, reducing the permanent deformation of the elastic supporting member 22, and extending the service life of the key assembly 20.

[0046] Furthermore, the first pressing member 21, the elastic support member 22 and the contact member 23 can form a button assembly 20 in an integrally formed manner. The button assembly 20 can be made of a soft elastic material, such as silicone. Silicone as the material of the button assembly 20 has excellent hand feel and comfort, a large contact area with the fingers, strong elasticity, and sensitive touch. It can relieve finger fatigue caused by pressing the buttons for a long time and improve the user's comfort. In addition, silicone is also heat-resistant, cold-resistant, acid-resistant and alkali-resistant, which can reduce the harm caused by the external environment to the button assembly 20 and increase the service life of the energy storage device 100. Optionally, the button assembly 20 can adopt a solid silicone fluidized molding production process, so that the button assembly 20 has the characteristics of high molding dimensional accuracy and simple assembly with other structures.

[0047] In some embodiments, silicone is used as the material of the button assembly 20. When the first pressing member 21 is pressed, the second space 131 provides space for the elastic support member 22 to shrink. The user can feel the physical response when pressing and can more intuitively feel the softness of the silicone button, reducing the fatigue caused by pressing.

[0048] The embodiment of the present application provides an energy storage device 100, wherein a button assembly 20 is disposed in a first mounting hole 11 of a control panel 10, and a switch 31 of a circuit board 30 faces the button assembly 20. The button assembly 20 includes a first pressing member 21, an elastic support member 22, and a contact member 23. The elastic support member 22 and the first pressing member 21 together enclose an installation space 24, and the contact member 23 is disposed in the installation space 24. The elastic support member 22 and the first pressing member 21 surround the contact member 23 inside, which can reduce the damage to the contact member 23 caused by moisture, dust, and impurities. A first abutting member 12 is disposed around the inner wall of the first mounting hole 11, and the first pressing member 21 has a first limiting member 211. A second space 131 is provided between the first limiting member 211 and the first abutting member 12 for being compressed when the button assembly 20 is pressed. When the first pressing member 21 is pressed, the second space 131 is compressed, and the first abutting member 12 is configured to abut against the first limiting member 211. After the first limiter 211 abuts against the first abutting member 12, the first pressing member 21 is restricted from moving toward the circuit board 30, reducing the problem of the key assembly 20 being pressed and collapsed, which may cause the key assembly 20 to malfunction. In addition, during the process of pressing the first pressing member 21, the elastic support member 22 can shrink and stretch in the second space 131. When the first pressing member 21 is pressed, due to the action of the elastic support member 22, the first pressing member 21 can rebound quickly and return to its original position, ensuring that the elastic support member 22 is deformed within a controllable range, reducing the pressure of the first pressing member 21 and the contact member 23 on the switch 31, reducing the permanent deformation of the elastic support member 22, and extending the service life of the energy storage device 100.

[0049] In some embodiments, please refer to Figure 7 and Fig. 9, the key assembly 20 further includes a second stopper 25. The first stopper 211 is connected to the end of the elastic support 22 away from the circuit board 30. The second stopper 25 is connected to the end of the elastic support 22 close to the circuit board 30. There is a limit space 13 between the first stopper 211 and the second stopper 25, and the limit space 13 includes a second space 131. The first abutting member 12 is arranged in the limit space 13. Along the direction from the first stopper 211 to the second stopper 25, the depth of the limit space 13 is greater than the length of the first abutting member 12. The control panel 10 further includes a second abutting member 14, and the second stopper 25 is clamped between the second abutting member 14 and the first abutting member 12. When the key assembly 20 is pressed, the second abutting member 14 can abut the second stopper 25 to move toward the circuit board 30, and the second abutting member 14 can abut the key assembly 20 so that the elastic support 22 generates elastic force, which is convenient for the key assembly 20 to recover. When the external force is removed, the first resisting member 12 can resist the second limiting member 25 to move toward the first pressing member 21 . The internal displacement of the second limiting member 25 is reduced by the resisting action of the first resisting member 12 and the second resisting member 14 .

[0050] In some embodiments, please refer to Figures 9 to 11 The first abutting member 12 is enclosed in the first mounting hole 11 to form a guide hole 121. Along the direction from the switch 31 to the key assembly 20, the guide hole 121 has a first opening 1211 close to the switch 31 and a second opening 1212 away from the switch 31. The size of the first opening 1211 is larger than the size of the second opening 1212. A guide slope 1213 is formed at the connection between the first opening 1211 and the second opening 1212. In the process of installing the key assembly 20 into the first mounting hole 11, the first pressing member 21 enters through the first opening 1211, enters the second opening 1212 along the guide slope 1213, and finally extends out of the first mounting hole 11. Since the second opening 1212 is smaller in size and is blocked by the first abutting member 12, the second limiting member 25 is clamped between the first abutting member 12 and the second abutting member 14, so that the key assembly 20 is installed in a fixed position. The guide hole 121 assists the button assembly 20 to enter the first mounting hole 11 . The button assembly 20 is made of silicone. Due to the softness of silicone, the button assembly 20 can be installed in place with the assistance of the guide hole 121 .

[0051] In some embodiments, please refer to Figures 9 to 11, a protective part 15 is provided on the surface of the control panel 10 facing the circuit board 30. The protective part 15 is arranged around the first mounting hole 11, and the second limiting part 25 is attached to the protective part 15. Further, the first opening 1211 communicates with the protective part 15, and the second limiting part 25 is arranged on the protective part 15. The second limiting part 25 can completely block the first opening 1211. Since the protective part 15 is arranged on the surface of the control panel 10 and is easily in contact with the external environment, the second limiting part 25 is closely attached to the protective part 15, forming a seal with the protective part 15, which can prevent moisture, dust, impurities, etc. in the external environment from entering the first mounting hole 11, playing a role in waterproofing and dustproofing.

[0052] Optionally, please refer to Figure 6 , Fig.10 and Fig.11 , the first limiting part 211 has a first waterproof surface 2111, and the first waterproof surface 2111 is attached to the inner wall of the first mounting hole 11. And / or, the second limiting part 25 has a second waterproof surface 251, and the second waterproof surface 251 is attached to the inner wall of the protective part 15. Since a part of the first limiting part 211 extends out of the first mounting hole 11 and is directly in contact with the external environment, moisture and dust easily enter the key assembly 20 along the gap between the first limiting part 211 and the inner wall of the first mounting hole 11. By providing the first waterproof surface 2111 on the first limiting part 211, the first waterproof surface 2111 forms a seal with the inner wall of the first mounting hole 11, which can reduce the entry of moisture and dust from outside the energy storage device 100 into the limiting space 13. Similar to the function of the first waterproof surface 2111, by providing the second waterproof surface 251 on the second limiting part 25, the second waterproof surface 251 forms a seal with the inner wall of the protective part 15, which can reduce the entry of moisture and dust from inside the energy storage device 100 into the limiting space 13. Through the dual protection of the first waterproof surface 2111 and the second waterproof surface 251, the waterproof and dustproof performance between the control panel 10 and the key assembly 20 is improved.

[0053] In some embodiments, please refer to Figure 7 , the first pressing part 21 further includes a pressing part 212 and a first connecting part 213. The first abutting part 12 is connected around the pressing part 212 through the first connecting part 213, and the contact part 23 is connected to the pressing part 212. Along the direction from the switch 31 to the key assembly 20, the thickness of the pressing part 212 is T1, the thickness of the first abutting part 12 is T2, and the thickness of the first connecting part 213 is T3, then T3 < T1 ≤ T2. Since the thickness of the first connecting part 213 is relatively thin, gently touching the first pressing part 21 can cause the pressing part 212 to sink towards the switch 31, improving the sensitivity and use comfort of the key assembly 20 and reducing the fatigue feeling generated by the fingers.

[0054] In some embodiments, please refer to Figure 7The energy storage device 100 includes a second connecting member 40 and a plurality of key components 20, wherein the second connecting member 40 is connected between two adjacent key components 20. Fig.12 and Fig.13 The surface of the control panel 10 facing the circuit board 30 is provided with a positioning groove 16 and a plurality of first mounting holes 11, and the positioning groove 16 is provided between adjacent first mounting holes 11. A positioning portion 41 is convexly provided on the second connecting member 40, and after the plurality of key assemblies 20 are installed in the plurality of first mounting holes 11, the positioning portion 41 is clamped in the positioning groove 16. The positioning portion 41 can identify the installation direction of the key assembly 20 and locate the installation position of the key assembly 20, thereby reducing the possibility of errors in the installation of the key assembly 20 and achieving the purpose of assisting the installation of the key assembly 20.

[0055] In some embodiments, please refer to Figure 3 , Figure 5 and Fig.12 The surface of the control panel 10 facing the circuit board 30 has a first positioning column 17, and the circuit board 30 has a first hole 32. When the circuit board 30 and the control panel 10 are installed, the first positioning column 17 is plugged into the first hole 32 to achieve accurate alignment of the electronic components on the control panel 10 and the circuit board 30. Among them, multiple first positioning columns 17 can be provided as needed. Furthermore, the surface of the control panel 10 facing the circuit board 30 also has a first fixing column 18, and the fixing column has a second hole 181, and the circuit board 30 has a third hole 33. Combined with Figure 8 The energy storage device 100 further includes a fastener 50, which may be a screw, a bolt, a pin, etc. The fastener 50 is inserted through the third hole 33 and the second hole 181 and fixedly connected to the first fixing column 18 to achieve the installation and fixation of the circuit board 30 and the control panel 10. The first fixing column 18 may be provided in plurality as required.
