[0035] As Figures 1 to 6As shown, a waterproof key structure 200 of an embodiment is used to be assembled to the connection port 120 through the guide groove 110 of the housing 100 of the battery 10. The waterproof key structure 200 includes a key 210 and a sealing elastic ring 220, including a key body 211 and a touch-pressure member 212 connected to each other. The key body 211 is used to be located in the guide groove 110, and the touch-pressure member 212 is penetrated through the connection port 120. The outer peripheral wall of the key body 211 adjacent to the end of the touch-pressure member 212 is convexly provided with a first limiting flange 2111, a second limiting flange 2121 is convexly provided at one end of the contact member 212 located in the accommodating cavity 130 of the housing 100, and the second limiting flange 2121 is used to be clamped with the inner wall of the accommodating cavity 130 of the housing; the sealing elastic ring 220 is sleeved on the outer peripheral wall of the contact member 212, and the sealing elastic ring 220 is used to be located in the guide groove 110, and one side of the sealing elastic ring 220 is in interference sealing contact with the first limiting flange 2111, and the other side of the sealing elastic ring 220 is in interference sealing contact with the inner wall of the accommodating cavity 130 of the housing 100. The sealing elastic ring 220 is connected to the inner wall of the guide groove 110, so that the button 210 body is reliably fixed in the guide groove 110 through the sealing elastic ring 220, and the sealing elastic ring 220 is in an extruded state, and the sealing elastic ring 220 and the second limiting flange 2121 are used to limit the button 210 together, so that the contact area between the first limiting flange 2111 and the inner wall of the guide groove 110 is increased respectively through the elastic deformation of the sealing elastic ring 220, and the resilience of the sealing elastic ring 220 due to the deformation can The contact pressure between the first limiting flange 2111 and the inner wall of the guide groove 110 can be increased, so that the sealing elastic ring 220 can fit more closely to the first limiting flange 2111 and the inner wall of the guide groove 110, thereby improving the sealing of the accommodating cavity 130, and further enabling the waterproof button structure 200 to effectively prevent external water from entering the accommodating cavity 130 through the gap between the first limiting flange 2111 and the inner wall of the guide groove 110, thereby greatly improving the waterproof ability of the battery 10.

[0036] like Figures 1 to 6 As shown, further, compared with the traditional button structure, the above-mentioned waterproof button structure 200 is simple and reliable, has a low assembly difficulty, and can effectively prevent external water from entering the accommodating cavity 130 through the gap between the first limiting flange 2111 and the inner wall of the guide groove 110 without using waterproof sealing glue, thereby reducing the production steps of the battery 10 and greatly improving the production efficiency of the battery 10.

[0037] In this embodiment, the sealing elastic ring 220 is in interference sealing contact with the first limiting flange 2111 through one side surface, and in interference sealing contact with the inner wall of the guide groove 110 through the other side surface, so that the sealing elastic ring 220 is in a squeezed state, the sealing elastic ring 220 is fixed at the bottom of the guide groove 110, and the accommodating cavity 130 is sealed; when the button 210 is pressed, the button body 211 gradually approaches the connection port 120, so that the pressure between the sealing elastic ring 220 and the button 210 gradually increases, and the elastic deformation of the sealing elastic ring 220 also increases accordingly. At the same time, the button body 211 pushes the pressing member 212 to make it deeper into the accommodating cavity 130; when the button 210 is released, the sealing elastic ring 220 returns to the state before being pressed, and during the rebounding process of the sealing elastic ring 220, the button 210 is pushed back to the position before being pressed.

[0038] For the above waterproof button 210 structure 200, since the sealing elastic ring 220 is sleeved on the outer peripheral wall of the pressing member 212, the sealing elastic ring 220 is used to be located in the guide groove 110. One side surface of the sealing elastic ring 220 is in interference sealing contact with the first limiting flange 2111, and the other side surface of the sealing elastic ring 220 is in interference sealing contact with the inner wall of the guide groove 110, so that the button 210 body is reliably fixed in the guide groove 110 through the sealing elastic ring 220, and the sealing elastic ring 220 is in a squeezed state. And the sealing elastic ring 220 and the second limiting flange 2121 are used to jointly limit the button 210, so as to increase the contact area with the first limiting flange 2111 and the inner wall of the guide groove 110 respectively through the elastic deformation of the sealing elastic ring 220. Moreover, the resilience force of the sealing elastic ring 220 due to deformation can increase the contact pressure with the first limiting flange 2111 and the inner wall of the guide groove 110, so that the sealing elastic ring 220 can fit more closely to the first limiting flange 2111 and the inner wall of the guide groove 110, improving the sealing performance of the accommodating cavity 130. Furthermore, the waterproof button structure 200 can effectively avoid the problem that external water enters the accommodating cavity 130 from the gap between the first limiting flange 2111 and the inner wall of the guide groove 110, greatly improving the waterproof ability of the battery 10.

[0039] Compared with the traditional button structure, the above waterproof button structure 200 is simple and reliable, with low assembly difficulty, and can effectively avoid the problem that external water enters the accommodating cavity 130 from the gap between the first limiting flange 2111 and the inner wall of the guide groove 110 without using waterproof sealant, reducing the production steps of the battery 10, and thus greatly improving the production efficiency of the battery 10.

[0040] Such as Figures 3 to 6As shown, in one embodiment, the circuit board 300 of the battery 10 is fixedly installed in the accommodation cavity 130. The pressing member 212 is located at one end of the accommodation cavity 130 and is arranged opposite to the contact point of the circuit board 300, so that the pressing member 212 can connect or disconnect the circuit of the circuit board 300 by contacting the contact point of the circuit board 300, enabling the waterproof button structure 200 to control the opening or closing of the battery 10.

[0041] As Figure 3 and Figure 6 As shown, in one embodiment, the pressing member 212 includes an abutting portion 2122 and a clamping portion 2123. One end of the abutting portion 2122 located in the guide groove 110 is fixedly connected to the button body 211. The clamping portion 2123 is arranged along the periphery of the abutting portion 2122. One end of the clamping portion 2123 located in the guide groove 110 is fixedly connected to the button body 211. Both the abutting portion 2122 and the clamping portion 2123 pass through the connection port 120. The second limiting flange 2121 is formed at one end of the clamping portion 2123 located in the accommodation cavity 130, so that the second limiting flange 2121 and the first limiting flange 2111 can jointly fix the sealing elastic ring 220 at the bottom of the guide groove 110; one end of the abutting portion 2122 located in the accommodation cavity 130 is arranged opposite to the contact point of the circuit board 300, so that the abutting portion 2122 can connect or disconnect the circuit of the circuit board 300 by contacting the contact point of the circuit board 300, enabling the waterproof button structure 200 to control the opening or closing of the battery 10.

[0042] As Figure 5 As shown, in one embodiment, the second limiting flange 2121 is formed with a clamping surface 2121a at the end adjacent to the connection port 120. The clamping surface 2121a extends along a plane parallel to the abutting surface of the second limiting flange 2121 and the inner wall of the accommodation cavity 130 to the side wall of the abutting portion 2122, so that the second limiting flange 2121 can be used to limit the button 210.

[0043] As Figure 5 As shown, in one embodiment, the second limiting flange 2121 is formed with a guiding inclined surface 2121b at the end far from the connection port 120. The guiding inclined surface 2121b extends to the side wall of the abutting portion 2122, so that when the button 210 is installed, the direct impact and friction of the outer shell 100 on the clamping portion 2123 are reduced, thereby protecting the clamping portion 2123 from damage.

[0044] The present disclosure also provides a battery 10, including a housing 100, a circuit board 300, and the waterproof button structure 200 described in any of the above embodiments; the button body is located in the guide groove, the second limiting flange 2121 is clamped with the inner wall of the accommodating cavity 130, and the sealing elastic ring 220 is located in the guide groove 110 to improve the sealing performance of the accommodating cavity 130, so that the waterproof button structure 200 can effectively prevent external water from entering the accommodating cavity 130 through the gap between the sealing elastic ring 220, the first limiting flange 2111, and the inner wall of the guide groove 110; the circuit board 300 is fixedly installed in the accommodating cavity 130, and the end of the pressing member 212 away from the button body 211 is arranged opposite to the contact point of the circuit board 300, so that the pressing member 212 can connect or disconnect the circuit of the circuit board 300 by contacting the contact point of the circuit board 300, enabling the waterproof button structure 200 to control the opening or closing of the battery 10.

[0045] As Figures 3 to 6 shown, in one embodiment, the first limiting flange 2111 is formed with a first smooth abutting surface 2111a, the inner wall of the guide groove 110 is formed with a second smooth abutting surface 111, the first smooth abutting surface 2111a and the second smooth abutting surface 111 are arranged opposite to each other, one side surface of the sealing elastic ring 220 is in interference sealing abutment with the first smooth abutting surface 2111a, and the other side surface of the sealing elastic ring 220 is in interference sealing abutment with the second smooth abutting surface 111, so that the sealing elastic ring 220 can respectively increase the contact area with the first smooth abutting surface 2111a and the second smooth abutting surface 111, further improving the waterproof ability of the waterproof button structure 200.

[0046] As Figure 3 shown, in one embodiment, the distance between the first smooth abutting surface 2111a and the second smooth abutting surface 111 is less than the thickness of the sealing elastic ring 220, so that the sealing elastic ring 220 can always be in a compressed state, enabling the sealing elastic ring 220 to respectively increase the contact area with the first limiting flange 2111 and the inner wall of the guide groove 110 through elastic deformation, and the sealing elastic ring 220 can also increase the pressure between the first limiting flange 2111 and the inner wall of the guide groove 110 through its own resilience, making the sealing elastic ring 220 more closely fit the first limiting flange 2111 and the inner wall of the guide groove 110, improving the sealing performance of the accommodating cavity 130.

[0047] As Figure 4As shown, in one embodiment, the sealing elastic ring 220 is a foamed silica gel ring or a rubber ring, so that the sealing elastic ring 220 has high resilience, low permanent deformation ability and good waterproof sealing performance. Compared with the elastic force of the traditional spring button structure being limited by the number of spring coils and the diameter, the waterproof button structure 200 can effectively avoid the phenomenon of insufficient elastic force caused by the limitation of the number of coils and the diameter in a narrow space through the sealing elastic ring 220, expanding the applicable range of the waterproof button structure 200.

[0048] As Figure 3 shown, in one embodiment, a clearance area 112 is formed between the outer peripheral wall of the sealing elastic ring 220 and the inner wall of the guide groove 110, so that when the button 210 is pressed, the sealing elastic ring 220 can have sufficient elastic deformation space to facilitate pressing the button 210.

[0049] As Figures 3 to 6 shown, in one embodiment, the abutting portion 2122 is disposed opposite to the contact of the circuit board 300, so that the abutting portion 2122 can connect or disconnect the circuit of the circuit board 300 by contacting the contact of the circuit board 300, enabling the waterproof button structure 200 to control the opening or closing of the battery 10.

[0050] As Figure 2 shown, in one embodiment, the battery 10 further includes an electric core 400, the electric core 400 is installed and fixed in the accommodation cavity 130, and the power output end of the electric core 400 is connected to the power input end of the circuit board 300, so that the electric core 400 can transmit power to the device connected to the battery 10 through the circuit board 300. When the circuit of the circuit board 300 is disconnected, the circuit board 300 can block the electric core 400 from transmitting power to the device connected to the battery 10, and when the circuit of the circuit board 300 is connected, the power of the electric core 400 can be transmitted to the device connected to the battery 10 through the circuit board 300.

[0051] In one embodiment, the battery 10 is an eye meter battery, so that the waterproof button structure 200 can improve the waterproof ability of the eye meter battery, thereby improving the service life of the eye meter battery.

[0052] Compared with the prior art, the present disclosure has at least the following advantages:

[0053] 1. For the above-mentioned battery 10, since the sealing elastic ring 220 is sleeved on the outer peripheral wall of the pressing member 212, the sealing elastic ring 220 is used to be located in the guide groove 110. One side surface of the sealing elastic ring 220 is in interference sealing contact with the first limiting flange 2111, and the other side surface of the sealing elastic ring 220 is in interference sealing contact with the inner wall of the guide groove 110, so that the main body of the button 210 is reliably fixed in the guide groove 110 through the sealing elastic ring 220, and the sealing elastic ring 220 is in a compressed state. The sealing elastic ring 220 and the second limiting flange 2121 are used to jointly limit the button 210, so as to increase the contact area with the first limiting flange 2111 and the inner wall of the guide groove 110 respectively through the elastic deformation of the sealing elastic ring 220. Moreover, the resilience force of the sealing elastic ring 220 due to deformation can increase the contact pressure with the first limiting flange 2111 and the inner wall of the guide groove 110, so that the sealing elastic ring 220 can be more closely attached to the first limiting flange 2111 and the inner wall of the guide groove 110, improving the sealing performance of the accommodating cavity 130. Furthermore, the waterproof button structure 200 can effectively avoid the problem that external water enters the accommodating cavity 130 through the gap between the first limiting flange 2111 and the inner wall of the guide groove 110, greatly improving the waterproof ability of the battery 10.

[0054] 2. Compared with the traditional button structure, the above-mentioned waterproof button structure 200 is simple and reliable, with a lower assembly difficulty. Moreover, it can effectively avoid the problem that external water enters the accommodating cavity 130 through the gap between the first limiting flange 2111 and the inner wall of the guide groove 110 without using waterproof sealant, reducing the production steps of the battery 10, and thus greatly improving the production efficiency of the battery 10.

[0055] The above embodiments only represent several implementation manners of the present disclosure. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the disclosed patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several deformations and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
