[0050] In related technologies, trucks are equipped with energy storage devices, and push-button switches are mounted on the housing of the energy storage devices. However, there are assembly gaps between the push-button switches and the housing. When the truck is in rainy weather or driving over puddles, water can easily splash onto the housing. The water splashed onto the housing can easily seep into the assembly gaps along the surface of the housing, or even seep into the housing, causing problems such as button corrosion and rust, and functional failure. Moreover, water seeping into the housing can easily damage components such as circuit boards and batteries housed inside the housing.

[0051] In view of this, such as Figure 1 , Figure 3 and Figure 6 As shown, this application embodiment provides a button structure 100 and an energy storage device 200. By setting a second body 22 of the sealing member 20 and sleeved on the button 10, and by setting the second body 22 to cause the first body 21 of the sealing member 20 to press the first end face 202a of the assembly hole 202 along the direction of pressing the button 10 under the action of the button 10, the sealing member 20 and the assembly hole 202 form a sealed space 30, and the sealing degree between the sealing member 20 and the assembly hole 202 is improved, thereby increasing the difficulty of water seeping into the sealed space 30, and thus increasing the difficulty of water seeping into the button 10 and the housing 201, improving the waterproof effect, and thereby reducing problems such as corrosion and rust of the button 10 and functional failure.

[0052] The following is in conjunction with the appendix Figure 1 To be continued Figure 6 The following describes some embodiments of this application in detail. Unless otherwise specified, the embodiments and features described below can be combined with each other.

[0053] like Figures 1 to 3 As shown, and in combination Figure 6 The button structure 100 provided in this embodiment is disposed in the housing 201 of the energy storage device 200. The housing 201 has an assembly hole 202. The button structure 100 includes a button 10 and a sealing member 20 sleeved on the button 10. The button 10 is installed in the assembly hole 202, which has a first end face 202a facing away from the housing 201. The sealing member 20 includes a first body 21 and a second body 22. The first body 21 and the second body 22 are connected along a first direction, which is the direction in which the button 10 is pressed. It can be understood that, from a top view, that is, from the direction from the sealing member 20 to the button 10, the first body 21 is located above the second body 22. Further, the second body 22 is sleeved on the button 10 and accommodated in the assembly hole 202. Along the first direction, the second body 22, under the action of the button 10, causes the first body 21 to press against the first end face 202a, so that the sealing member 20 and the assembly hole 202 form a sealing space 30.

[0054] In this embodiment, the second body 22 of the sealing member 20 is sleeved on the button 10 and assembled into the mounting hole 202 through the button 10. This allows the button 10 to apply pressure in a first direction to the second body 22 when it is assembled into the housing 201. That is, from a top view, the button 10 applies downward pressure to the second body 22. The first body 21 is connected to the side of the second body 22 away from the housing 201. Thus, during assembly, the first body 21 can press against the first end face 202a of the mounting hole 202 in the first direction under the action of the second body 22. This allows the second body 22 to press the first end face 202a in the first direction during assembly, thereby improving the sealing degree between the sealing member 20 and the mounting hole 202, improving the sealing performance of the sealing space 30, and improving the waterproof effect. In this way, when encountering situations such as rainy days where water may splash onto the housing 201, the seal 20 can, to a certain extent, prevent water from entering the sealed space 30. This increases the difficulty for water to seep from between the seal 20 and the housing 201 into the sealed space 30 formed by the seal 20 and the mounting hole 202. Consequently, it increases the difficulty for water to seep into the gap between the housing 201 and the button 10, reducing the occurrence of corrosion, rust, and functional failure of the button 10.

[0055] like Figure 2 As shown, in some embodiments, the first body 21 and the second body 22 are integrally formed and connected to enhance the waterproof function of the seal 20.

[0056] like Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments, the assembly hole 202 has a first hole segment 2021 and a second hole segment 2022. Along a first direction, the first hole segment 2021 is connected to the side of the second hole segment 2022 facing away from the housing 201. That is, from a top view, the second hole segment 2022 is located below the first hole segment 2021. The first hole segment 2021 has a first end face 202a facing away from the housing 201. The diameter of the first hole segment 2021 is larger than the diameter of the second hole segment 2022, such that the second hole segment 2022 forms a face towards the first end face 2021. The second end face 202b of the first hole segment 2021 can be understood as the stepped end face connecting the first hole segment 2021 and the second hole segment 2022; the button 10 passes through and connects to the second hole segment 2022, and part of the button 10 is located in the first hole segment 2021; the second body 22 is assembled into the first hole segment 2021 through the button 10, and the second body 22 is housed in the first hole segment 2021 and presses against the second end face 202b; the first body 21 presses against the first end face 202a of the first hole segment 2021.

[0057] In this embodiment, the second body 22 is sleeved on the button 10 and assembled into the first hole segment 2021 through the button 10. During assembly, the button 10 is inserted downward into the second hole segment 2022, so that the button 10 can apply pressure in the first direction to the second body 22 during assembly. The first body 21 is connected to the side of the second body 22 away from the housing 201. Thus, the second body 22, which is housed in the first hole segment 2021, is subjected to the downward pulling force of the button 10 to press the second end face 202b, thereby pressing the first end face 202a downward on the side of the assembly hole 202 away from the housing 201.

[0058] like Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments, the second body 22 is provided with a first protrusion 221, and the part of the button 10 installed above the mounting hole 202 is provided with a second protrusion 10a. From a top view, the first protrusion 221 is embedded below the second protrusion 10a, so that the second body 22 is sleeved on the button 10. Under the action of the button 10, the second protrusion 10a presses the first protrusion 221 along the first direction, so that the first body 21 presses the first end face 202a, and the second body 22 presses the second end face 202b, thereby achieving a good seal between the seal 20 and the mounting hole 202. For example, the first protrusion 221 is connected to the side of the second body 22 opposite to the first body 21 and extends along the first aperture direction of the mounting hole 202 (that is, towards the center line i of the mounting hole 202), and the second protrusion 10a extends from the outer peripheral surface of the button 10 along the second aperture direction of the mounting hole 202 (that is, towards the direction opposite to the center line i of the mounting hole 202), and the first aperture direction and the second aperture direction are opposite.

[0059] like Figures 2 to 4 As shown, and in combination Figure 6 In some embodiments, the button structure 100 further includes a fastener 40 located within the housing 201. The button 10 is mounted to the mounting hole 202 via the fastener 40 to reinforce the connection between the button 10 and the housing 201. For example, the fastener 40 is a nut. During assembly, the second body 22 of the seal 20 is fitted onto the button 10, and then the button 10 is passed through the second hole 2022 from top to bottom. Subsequently, the fastener 40 is used to lock the button 10 and the housing 201. During the process of locking the button 10 with the fastener 40, the button 10 moves downwards or has a downward tendency, causing the button 10 to push the second protrusion 10a downwards against the first protrusion 221. This causes the second body 22 to be subjected to downward pressure, resulting in the second body 22 pressing against the second end face 202b, and the first body 21 pressing against the first end face 202a.

[0060] like Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments, the button 10 includes a first part 11 and a second part 12. The first part 11 and the second part 12 are connected sequentially along a first direction. The first part 11 and the second part 12 can be integrally formed and connected. The second protrusion 10a is provided on the outer peripheral surface of the first part 11. The first part 11 is located in the first hole segment 2021 and accommodated in the sealing space 30. The second part 12 is installed in the second hole segment 2022, so that the button 10 is installed in the mounting hole 202. Specifically, the second part 12 can be fixed to the second hole segment 2022 by fasteners 40 to stabilize the connection between the second part 12 and the housing 201. The second body 22 is sleeved on the first part 11, and the outer peripheral surface of the second body 22 presses against the inner peripheral surface of the first hole segment 2021 to improve the sealing performance between the second body 22 and the first hole segment 2021.

[0061] like Figure 2 , Figure 3 and Figure 6 As shown, in one specific embodiment, the outer peripheral surface of the second part 12 is provided with an external thread 121, and the fastener 40 is provided with a threaded hole 41. The second part 12 passes through the threaded hole 41 and is fastened to the second hole section 2022 by the fastener 40. In this way, when assembling the button 10 and the housing 201, the fastener 40 can be rotated to move the fastener 40 relative to the second part 12 toward the seal 20, so as to tighten the second part 12, the housing 201 and the fastener 40.

[0062] like Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, the first body 21 includes a flexible sealing shell 211. The flexible sealing shell 211 and the second body 22 are connected along a first direction. The flexible sealing shell 211 is located on the side of the assembly hole 202 away from the housing 201. Specifically, the flexible sealing shell 211 is located on the side of the first hole segment 2021 away from the second hole segment 2022. The flexible sealing shell 211 is connected to the assembly hole 202 through the second body 22 and protects the button 10 assembled on the housing 201. The outer diameter of the flexible sealing shell 211 is larger than the outer diameter of the second body 22, so that in the first direction, the flexible sealing shell 211 presses against the first end face 202a of the first hole segment 2021 towards one end face of the housing 201, thereby achieving the sealing of the seal 20 with the assembly hole 202.

[0063] like Figure 2 , Figure 5 and Figure 6As shown, in some embodiments, the first body 21 further includes a protrusion 212, which is disposed on the side of the flexible sealing shell 211 facing the button 10 and located within the sealed space 30. Specifically, the protrusion 212 extends from the flexible sealing shell 211 along a first direction. The protrusion 212 contacts the button 13 of the button 10, or a gap is formed between the protrusion 212 and the button 13 of the button 10, so that when the flexible sealing shell 211 is pressed along the first direction, the protrusion 212 presses the button 13 of the button 10 to realize the opening and closing of the button 10. Here, the button 13 is a movable part on the button 10, and the first direction can also be understood as the arrangement direction of the protrusion 212 and the button 10.

[0064] For example, the flexible sealing shell 211 has a groove (not shown) with an opening facing the button 10, the protrusion 212 is integrally connected to the wall of the groove facing the button 10, and the second body 22 is annular.

[0065] like Figure 2 and 3 As shown, in some embodiments, the housing 201 is provided with an annular protrusion 203 surrounding the button 10. The annular protrusion 203 surrounds and forms a first hole segment 2021. The annular protrusion 203 can support the first body 21, and the first end face 202a is formed on the side of the annular protrusion 203 facing away from the housing 201.

[0066] like Figure 1 and Figure 2 As shown, in some embodiments, the seal 20 is made of silicone; and / or, the button 10 is an illuminated button.

[0067] In this embodiment, the sealing element 20 is made of soft silicone or other elastic material, allowing the user to press the button 10 by pressing the sealing element 20. In this embodiment, the button 10 can be an illuminated button, which integrates button operation and indicator light display, and can indicate the status of the energy storage device 200. In specific applications, pressing and holding the button 13 of the illuminated button will turn on the illuminated button, at which time the indicator light of the illuminated button will light up.

[0068] like Figure 1 and Figure 3 As shown, this embodiment also provides an energy storage device 200, which includes a housing 201 and a button structure 100 as described in any of the above embodiments. The housing 201 is provided with an assembly hole 202, and the button 10 is installed in the assembly hole 202.

[0069] The energy storage device 200 of this embodiment, by providing a button structure 100 on the housing 201 as in any of the above embodiments, can increase the difficulty of water seeping into the gap between the housing 201 and the button 10, improve the waterproof effect, and thus effectively avoid the phenomenon of the button 10 being corroded and rusted, or failing to function, as well as reduce the phenomenon of water seeping into the housing 201 and damaging the devices housed in the housing 201.

[0070] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the housing 201 includes an upper cover 201a and a lower cover (not shown). An assembly hole 202 is provided in the upper cover 201a, and the upper cover 201a and the lower cover are assembled together to form an accommodating space. The energy storage device 200 also includes an energy storage module (not shown) and / or a circuit board (not shown). The energy storage module is disposed in the accommodating space and includes at least one of a supercapacitor and a battery. The battery includes at least one of a sodium battery, a lithium battery, and a lead-acid battery. The circuit board is disposed in the accommodating space. In this embodiment, the housing 201 can protect the energy storage module and the circuit board disposed within the accommodating space.

[0071] Combination Figure 1 In some embodiments, the energy storage device 200 includes at least one of an automotive battery, an emergency jump starter (such as a portable emergency jump starter), an outdoor energy storage power source, a start-stop power source, and a power tool. In specific applications, the energy storage device 200 is configured on self-moving equipment such as trucks, at least for powering the self-moving equipment.

[0072] Combination Figure 1 In some embodiments, the energy storage device 200 includes a connection terminal (not shown), an energy storage module (not shown), and a circuit board (not shown). The circuit board connects the energy storage module and the connection terminal. The connection terminal is used to connect to an external device, and the energy storage module supplies power to the external device through the connection terminal. Further, the circuit board includes a control module and a switch module. The control module is connected to a button structure 100 and outputs a control signal based on a pressing signal from the button structure 100. The switch module connects the connection terminal and the energy storage module and conducts a power path between the energy storage module and the connection terminal based on the control signal from the control module, enabling the energy storage device 200 to supply power to the external device. The connection terminal includes a first connection terminal and a second connection terminal, one of which is a positive terminal and the other is a negative terminal. The external device includes at least one of a parking air conditioner and an engine. It should be understood that the external device is not part of the energy storage device 200.
