[0056] See also Figures 2 to 4In some embodiments, the energy storage device 1000 includes a button assembly 100, which includes a shell 10, a pressing member 20, a reset structure 30 and a limiting structure 40. The shell 10 is provided with a mounting groove 11; the pressing member 20 is at least partially located in the mounting groove 11; the pressing member 20 can move along the pressing direction under the action of an external force to trigger the switch element 51 of the energy storage device 1000; the reset structure 30 is at least partially connected to the bottom wall of the mounting groove 11; the reset structure 30 is used to apply a reset force to the pressing member 20 so that the pressing member 20 can move in a direction opposite to the pressing direction and reset; the reset structure 30 is also used to apply a supporting force to the pressing member 20 when the pressing member 20 moves along the pressing direction; the limiting structure 40 is provided on the pressing member 20, and the limiting structure 40 is used to limit the pressing member 20.

[0057] In the key assembly 100 of the above embodiment, the limiting structure 40 can limit the pressing member 20, so that the user can trigger the switch element 51 by pressing any position of the pressing surface of the pressing member 20, effectively reducing the situation that the pressing member 20 is easy to tilt when being pressed, ensuring the stability of the pressing action of the pressing member 20, and improving the pressing feel of the pressing member 20 and the user's experience; in addition, the limiting structure 40 can also prevent the pressing member 20 from easily escaping from the mounting groove 11 when resetting, ensuring the stability of the resetting action of the pressing member 20, improving the reliability of the pressing member 20, and providing a guarantee for the pressing member 20 to trigger the switch element 51 when being pressed later. The reset structure 30 can provide a supporting force to support the pressing member 20 when the pressing member 20 is pressed, improving the pressing feel of the pressing member 20, so that the pressing member 20 can trigger the switch element 51 more gently and smoothly, and preventing the pressing member 20 from acting on the switch element 51 with excessive force and damaging the switch element 51. In addition, compared with the reset structure 30 abutting against the circuit board 52, the reset structure 30 of this embodiment is at least partially connected to the bottom wall of the mounting groove 11 of the housing 10, and the reset structure 30 does not need to contact the circuit board 52. Therefore, during the assembly or use of the button assembly 100, the reset structure 30 is not easy to damage the circuit board 52.

[0058] Exemplarily, the functions corresponding to the switch element 51 include at least one of the following: turning on the energy storage device 1000 to charge an external power device; turning off the energy storage device 1000 to charge an external power device; turning on the external power supply device to charge the energy storage device 1000; turning off the external power supply device to charge the energy storage device 1000; indicating or displaying the power level of the energy storage device 1000 when the energy storage device 1000 does not charge an external power device or the external power supply device does not charge the energy storage device 100; turning on and / or off the light-emitting element (not marked) of the energy storage device 100, the light-emitting element is used to indicate the power level of the energy storage device 100 or to illuminate, and the light-emitting element includes an LED lamp or other light-emitting device. For example, the corresponding function is realized by pressing the pressing member 20 for a certain time and / or number of times: the energy storage device 1000 needs to be turned on or off by pressing the pressing member 20 for at least 5 seconds, the pressing member 20 needs to be pressed briefly to activate the power indicator light, and the pressing member 20 needs to be pressed twice quickly to turn on the light-emitting element, etc.

[0059] See also Figure 4 In some embodiments, the housing 10 is formed with an opening 12 and a through hole 13. The through hole 13 is used for the switch element 51 to pass through. The through hole 13 is arranged on the bottom wall of the mounting groove 11. The opening 12 and the through hole 13 are respectively connected to the mounting groove 11. The pressing member 20 and the reset structure 30 can enter the mounting groove 11 through the opening 12. Since the opening 12 is connected to the mounting groove 11, when the key assembly 100 is assembled, the pressing member 20 and the reset structure 30 can enter the mounting groove 11 through the opening 12, which provides a guarantee for the pressing member 20 and the reset structure 30 to be installed on the housing 10; in addition, since the through hole 13 is connected to the mounting groove 11, at least part of the pressing member 20 located in the mounting groove 11 can move along the pressing direction to contact the switch element 51 and trigger the switch element 51 when pressed by an external force, so that the energy storage device 1000 performs the function corresponding to the switch element 51.

[0060] See also Figure 4 and Figure 5In some embodiments, the pressing member 20 includes a pressing portion 21 and a triggering portion 22. The pressing portion 21 is used for being pressed by an external component or a user. The limiting structure 40 includes a step wall 41 formed on the pressing portion 21. The step wall 41 is used to contact the top periphery of the mounting groove 11 to limit the movement of the pressing member 20 in the pressing direction. The triggering portion 22 is connected to the pressing portion 21. The triggering portion 22 can move under the drive of the pressing portion 21 to trigger the switch element 51. Exemplarily, the radial dimension of the pressing portion 21 is greater than the radial dimension of the triggering portion 22, so that the triggering portion 22 can contact the trigger switch element 51, and the pressing portion 21 has a larger pressing area or pressing region, thereby improving the user's pressing feel; and the step wall 41 formed at the pressing portion 21 can contact the top periphery of the mounting groove 11, thereby limiting the movement of the pressing member 20 in the pressing direction; it is also conducive to achieving a lightweight design of the product. When the pressing member 20 moves along the pressing direction until the step wall 41 contacts the top periphery of the mounting groove 11, the pressing member 20 moves along the pressing direction to the first limit position, so that the step wall 41 limits the pressing member 20 during the pressing process, preventing the pressing member 20 from continuing to move along the pressing direction after moving along the pressing direction to the first limit position, causing the pressing member 20 to apply too much force to the switch element 51 and / or the reset structure 30, which may damage the switch element 51 and / or the reset structure 30. Therefore, the key assembly 100 of this embodiment can protect the switch element 51 and / or the reset structure 30 to a certain extent. Exemplarily, the pressing surface of the pressing member 20 is formed on the side of the pressing portion 21 away from the trigger portion 22, and the shape of the pressing surface of the pressing member 20 can be designed according to actual needs, such as a plane or a curved surface.

[0061] See also Figure 5 and Figure 6 In some embodiments, the reset structure 30 includes an elastic member 31, one end of the elastic member 31 abuts against the pressing member 20, and the other end of the elastic member 31 abuts against the bottom wall of the installation groove 11. The reset structure 30 of this structure is simple in structure and easy and fast to install. Exemplarily, the elastic member 31 includes a spring or other elastic structure.

[0062] The number of elastic members 31 can be set according to actual needs, such as one, two, three or more. Exemplarily, the number of elastic members 31 includes one. Exemplarily, the number of elastic members 31 includes two, and the projections of the two elastic members 31 on the bottom wall of the mounting groove 11 are respectively located on both sides of the switch element 51. The number of elastic members 31 includes two, and the two elastic members 31 are arranged at intervals, so that the support force or restoring force from the reset structure 30 on the pressing member 20 can be stronger, thereby improving the pressing feel of the operator.

[0063] See also Figure 5In some embodiments, the key assembly 100 further includes a circuit board 52, the circuit board 52 is electrically connected to the switch element 51, and the circuit board 52, the bottom wall of the mounting groove 11, and the elastic member 31 are arranged in sequence. In this way, the circuit board 52 does not need to enter the mounting groove 11 through the opening 12, and the circuit board 52, the elastic member 31, and the pressing member 20 will not interfere with each other during installation, preventing the elastic member 31 and the pressing member 20 from damaging the circuit board 52 during installation. Exemplarily, the switch element 51 is arranged toward the pressing member 20 to ensure that the pressing member 20 can trigger the function corresponding to the switch element 51 when pressed.

[0064] In some embodiments, the reset structure 30 includes a first magnetic member (not shown) and a second magnetic member (not shown), wherein the first magnetic member is disposed on the pressing member 20; the second magnetic member is disposed opposite to the first magnetic member with the same magnetic pole, and the second magnetic member is disposed on the bottom wall of the mounting groove 11. The pressing member 20 can move along the pressing direction under the action of an external force to trigger the switch element 51, thereby realizing the corresponding function of the switch element 51. The mutual repulsion force generated by the mutual repulsion of the first magnetic member and the second magnetic member with the same magnetic pole is used to support and reset the pressing member 20, wherein the magnetic force of the second magnetic member on the first magnetic member can be applied to the first magnetic member and the pressing member 20 more evenly, which can minimize the problem of the pressing member 20 shaking due to uneven force and affecting the hand feel, and at the same time, the magnetic force of the second magnetic member on the first magnetic member can be stably applied vertically to the first magnetic member, ensuring that the pressing member 20 provided with the first magnetic member can be stably reset. Exemplarily, the first magnetic attraction member (or the second magnetic attraction member) includes at least one of the following: a magnet, an electromagnet, etc.

[0065] See also Figure 5 In some embodiments, one of the limiting structure 40 and the housing 10 includes a buckle portion 61, and the other includes a matching portion 62, and the buckle portion 61 is used to engage with the matching portion 62 to limit the movement of the pressing member 20. When the pressing member 20 is reset to the engagement of the buckle portion 61 and the matching portion 62 under the action of the reset force of the reset structure 30, the pressing member 20 moves to the second limit position in the direction opposite to the pressing direction, so that the locking and matching of the buckle portion 61 and the matching portion 62 are used to limit the position of the pressing member 20 during the reset, so as to prevent the pressing member 20 from moving in the direction opposite to the pressing direction to the second limit position and then continuing to move in the direction, so that the pressing member 20 may be disengaged from the mounting groove 11. Exemplarily, the limiting structure 40 includes the buckle portion 61, and the housing 10 includes the matching portion 62; or, the housing 10 includes the buckle portion 61, and the limiting structure 40 includes the matching portion 62.

[0066] In some embodiments, when the pressing member 20 moves along the pressing direction under the action of external force, the limiting structure 40 is used to limit the movement of the connection between the pressing member 20 and the limiting structure 40 in the direction opposite to the pressing direction, so as to prevent the pressing member 20 from easily falling out of the mounting groove 11 during resetting, thereby effectively ensuring the stability of the resetting action of the pressing member 20.

[0067] The number of the limiting structures 40 can be designed according to actual needs. For example, the number of the limiting structures 40 includes at least two, wherein the two limiting structures 40 are arranged on opposite sides of the pressing member 20. In this way, the two limiting structures 40 located on opposite sides of the pressing member 20 can respectively limit the pressing member 20, thereby improving the limiting effect on the pressing member 20 and effectively ensuring the stability of the pressing action and the stability of the reset action of the pressing member 20. It can be understood that Figure 7 The buckle portion 61 shown in the figure is buckled with the matching portion 62, which is not shown.
