DETAILED DESCRIPTION

[0029] The following is a more detailed description of a waterproof keypad and electronic product of the present invention, with reference to the accompanying drawings. Preferred embodiments of the present invention are shown, and it should be understood that those skilled in the art may modify the present invention described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as a general guideline for those skilled in the art and not as a limitation of the present invention.

[0030] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0031] like Figure 1-Figure 2As shown, the embodiment of the present invention provides a simple and practical waterproof button, which includes a button body 1, a filling structure 2 and a clamping member 3.

[0032] Specifically, one end of the key body 1 passes through the mounting slot 41 of the housing 4 and extends into the interior of the housing 4 to trigger the switch 5 in the housing 4; the other end of the key body 1 is used to receive user input; one end of the key body 1 is provided with a slot 11; the clip 3 is mounted on the slot 11 and located inside the housing 4 to prevent the key body 1 from falling out of the housing 4; the filling structure 2 is located between the key body 1 and the mounting slot 41 of the housing 4, and can provide elastic restoring force after the key body 1 is pressed and form a waterproof sealing structure. Through double-shot injection molding technology, multiple parts of this embodiment (such as the key body 1 and the filling structure 2) are simplified into a single part, reducing the number of parts and assembly relationships required for assembly. The filling structure 2 set between the key body 1 and the housing 4 not only provides elastic restoring force, but also forms a waterproof sealing structure, enhancing the waterproof ability of the product. The setting of the filling structure 2 not only effectively prevents moisture from entering the device through the gap between the key body 1 and the housing 4, improving the waterproof performance of the device, but also provides a good pressing feel and enhances the user's operating experience.

[0033] In this embodiment, a card slot 11 is provided at one end of the movable plate 111 away from the pressing plate 110 , which, together with the use of the card member 3 , can prevent the key body 1 from falling off from the housing 4 , thereby improving the safety and reliability of the key.

[0034] Those skilled in the art will appreciate that the shapes and sizes of the pressing plate 110 and the movable plate 111 can be adjusted according to actual needs to accommodate the requirements of different devices, thereby providing design flexibility.

[0035] In one embodiment, the key body 1 includes a pressing plate 110 and a movable plate 111. Specifically, one side of the pressing plate 110 is connected to the movable plate 111, and the other side is used to receive user input. A first predetermined spacing exists between one side of the pressing plate 110 and the mounting slot 41. The end of the movable plate 111 distal from the pressing plate 110 extends into the interior of the housing 4, and a second predetermined spacing exists between the sidewall of the movable plate 111 and the inner sidewall of the mounting slot 41. The filling structure 2 fills the first and second predetermined spacings. The engaging slot 11 is provided at the end of the movable plate 111 distal from the pressing plate 110. One side of the pressing plate 110 receives user input, allowing the user to intuitively operate the key. Filling the filling structure 2 to the first and second predetermined spacings not only provides elastic restoring force, ensuring that the key body 1 quickly rebounds after being pressed, but also enhances the tactile feel of the key body 1.

[0036] Preferably, the pressing plate 110 and the movable plate 111 are integrally formed. This integral molding reduces weak points at the joints, enhancing the strength and durability of the overall structure. Furthermore, this integral molding reduces potential gaps and seams, helping to create a tighter waterproof seal. By eliminating the need for multiple parts, the integrally formed structure reduces the potential for dimensional tolerance accumulation and improves product precision.

[0037] In this embodiment, a plurality of grooves 1101 are provided on one side of the pressing plate 110. Specifically, the filling structure 2 fills the grooves 1101. The provision of grooves 1101 increases the thickness of the soft rubber of the filling structure 2. This increased thickness increases the deformable space of the soft rubber, thereby enhancing the rebound feel and allowing the pressing plate 110 to rebound more effectively after being pressed. Furthermore, it increases the contact area between the key body 1 and the filling structure 2, preventing the filling structure 2 from separating from the key body 1.

[0038] In this embodiment, the key body 1 is made of hard plastic. Hard plastic generally has high hardness and wear resistance, making the key body 1 more durable and able to withstand the wear and tear of long-term use. Hard plastic also provides better structural stability, making the key body 1 less likely to deform during repeated pressing. The hard plastic key body 1 provides clear press feedback, ensuring that each key operation is accurately triggered.

[0039] Preferably, the key body 1 has a T-shaped cross-section. This T-shaped structure typically offers enhanced bending and torsion resistance, making the key body 1 more robust and less susceptible to deformation during prolonged use. This T-shaped structure facilitates a tighter seal and, in conjunction with the filling structure 2, further enhances waterproofing.

[0040] Preferably, the filling structure 2 is made of a flexible soft rubber material. The soft rubber material has excellent elasticity. When the key is pressed, the filling structure 2 made of the soft rubber material can quickly return to its original shape, providing a good rebound effect. The soft rubber filling structure 2 can absorb some of the impact of the pressing force, reducing damage to the key body 1 and internal components.

[0041] In addition, the filling structure 2 includes a first filling layer 21 and a second filling layer 22 connected to each other. The key body 1 passes through the first and second filling layers 21 and 22 in sequence. The first filling layer 21 is provided with a plurality of first protrusions 211 and a plurality of second protrusions 212. The first protrusions 211 are located within the groove 1101, and the second protrusions 212 are closely attached to the inner sidewall of the mounting groove 41. The second filling layer 22 is perpendicular to the first filling layer 21. The second filling layer 22 is provided with a third protrusion 221, which is closely attached to the inner sidewall of the mounting groove 41. The arrangement of the plurality of first protrusions 211, the plurality of second protrusions 212, and the third protrusion 221 allows for a better fit to the inner sidewall of the mounting groove 41, improving sealing. The combination of the groove 1101 and the first protrusions 211 increases the thickness of the soft rubber of the filling structure 2. This increased thickness increases the space within which the soft rubber can deform, thereby enhancing the rebound feel and allowing the pressing plate 110 to rebound more effectively after being pressed. The second protrusion 212 is in close contact with the inner side wall of the installation groove 41 , and the third protrusion 221 on the second filling layer 22 is in close contact with the inner side wall of the installation groove 41 , providing additional sealing protection for the whole.

[0042] Preferably, the plurality of first protrusions 211, the plurality of grooves 1101, and the plurality of second protrusions 212 are symmetrically arranged around the center of the pressing plate 110. This symmetrical arrangement ensures that the pressing plate 110 is subjected to uniform force in all directions, improving the stability and consistency of key operation. The symmetrical arrangement of the protrusions and grooves 1101 can provide a more balanced and comfortable pressing feel, improving the user experience. The symmetrical arrangement of the first protrusions 211 and grooves 1101 helps the key return to its original shape more evenly after being pressed, improving the key's resilience.

[0043] In addition, the symmetrical first protrusion 211 and the second protrusion 212 can fit more tightly with the inner wall of the installation groove 41, thereby enhancing the sealing effect and improving the waterproof performance.

[0044] In this embodiment, the diameter of the clamping member 3 is larger than the diameter of the mounting groove 41. This larger diameter of the clamping member 3 allows the clamping member 3 to be securely fastened within the housing 4, preventing the key body 1 from falling out of the mounting groove 41 when subjected to external forces. This improves the stability of the key body 1 and prevents accidental falling, thereby enhancing the user experience.

[0045] Preferably, the clamping member 3 comprises a retaining spring. The elastic properties of the retaining spring can provide a stable fixing force, reducing the displacement of the key body 1 caused by vibration or impact. The retaining spring has a self-locking property and can automatically maintain a fixed state after installation without the need for an additional locking mechanism.

[0046] Furthermore, the clamping groove 11 is an annular structure. The provision of the annular clamping groove 11 simplifies the installation process of the clamping spring, making it easier to clamp in or take out the clamping spring.

[0047] In addition, combined Figure 3 and Figure 4 As shown, this embodiment also provides an electronic product, including the waterproof button as described above, and also including a housing 4 and a switch 5.

[0048] Specifically, the switch 5 is arranged inside the shell 4; the outer wall of the shell 4 is provided with a mounting groove 41; the button body 1 of the waterproof button extends into the inside of the shell 4 through the mounting groove 41 and maintains a predetermined interval with the switch 5; the clamp 3 of the waterproof button abuts against the inner wall of the shell 4.

[0049] The predetermined interval between the button body 1 and the switch 5 can reduce false triggering caused by accidental touch.

[0050] The electronic product in this embodiment may include AR glasses or other small electronic products.

[0051] In this embodiment, the user presses the button body 1 located on the housing 4, and transmits force to the movable plate 111 through the pressing plate 110, thereby triggering the switch 5 inside the housing 4 to achieve control or function selection of the electronic product.

[0052] In summary, the waterproof button and electronic product proposed by the present invention have the following advantages:

[0053] The key body, the filling structure, and the clip are arranged such that one end of the key body passes through the mounting slot of the housing and extends into the interior of the housing to trigger the switch in the housing; the other end of the key body is used to receive user input; one end of the key body is provided with a clip slot; the clip is mounted on the clip slot and located inside the housing to prevent the key body from falling out of the housing; the filling structure is located between the key body and the mounting slot of the housing, and can provide elastic restoring force after the key body is pressed, thereby forming a waterproof seal. This device can not only achieve a waterproof seal, but also reduce the risk of assembly failure caused by the accumulation of component tolerances, thereby increasing product reliability. It also has a simple structure, is easy to assemble, and has high space utilization.

[0054] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
