Technical Field

[0001] The utility model relates to a waterproof key structure. Background Art

[0002] Under the current technical background, waterproof side buttons have many parts, or are complex to assemble, or occupy a large space, and are unstable in waterproofing. As electronic products become more and more integrated and miniaturized and pursue cost-effectiveness, a side button with a simple structure, small space occupation, and stable installation is needed. Summary of the invention

[0003] The purpose of the present invention is to provide a waterproof key structure to solve the problems raised in the above background technology. To achieve the above purpose, the present invention provides the following technical solutions:

[0004] A waterproof key structure comprises a shell and a key. A circuit board is installed inside the shell, and the circuit board is provided with a key switch. The shell is provided with a key mounting hole, and the key is mounted to the key mounting hole. The key moves to touch or leave the key switch. A sealing ring is provided between the key and the shell. When the key moves toward the key switch and touches, the sealing ring is in a compressed state. The sealing ring is made of elastic material. When the sealing ring recovers its elasticity, it pushes the key to leave the key switch.

[0005] Furthermore, the sealing ring is made of gas phase silica gel material.

[0006] Furthermore, the button is provided with a buckle, and the shell is provided with a buckle overlapping portion, the buckle is buckled on the buckle overlapping portion to limit the button from being separated from the shell, the buckle is arranged on the outside of the button, one end is buckled on the buckle overlapping portion, and the other end exposes the mounting hole, and a disassembly space is provided between the buckle and the button.

[0007] Furthermore, the buckle is provided with an avoidance slope, and the avoidance slope guides the buckle to avoid obstruction and enter into connection with the buckle overlap portion when the button is installed.

[0008] The beneficial effect of the utility model is that in the key of the utility model, the key can return to its original position after being pressed through the effect of the elastic sealing ring. Here, one sealing ring solves the two functions of sealing and returning to its original position, and the structure is compact, simple and easy to install. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] In the present invention, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0015] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0016] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0017] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0018] It should also be understood that the terms used in the utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in the utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0019] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0020] See Figure 1 and 2 A waterproof key structure comprises a shell 1 and a key 2. A circuit board 3 is installed inside the shell 1. The circuit board 3 is provided with a key switch 31. The shell 1 is provided with a key mounting hole 11. The key 2 is mounted to the key mounting hole 11. The key 2 moves to touch or leave the key switch 31. A sealing ring 4 is arranged between the key 2 and the shell 1. When the key 2 moves toward the key switch 31 to touch, the sealing ring 4 is in a compressed state. The sealing ring 4 is made of elastic material. When the sealing ring 4 recovers elastically, it pushes the key 2 to leave the key switch 31.

[0021] In the key of the utility model, the elastic sealing ring can realize the key returning to its original position after being pressed. Here, one sealing ring solves the two functions of sealing and returning to its original position, and the structure is compact, simple and easy to install.

[0022] As a further solution of the utility model: the sealing ring 4 is made of gas phase silica gel material.

[0023] As a further solution of the utility model: the button 2 is provided with a buckle 21, the housing 1 is provided with a buckle overlap portion 12, the buckle 21 is buckled in the buckle overlap portion 12 to limit the button from being separated from the housing 1, the buckle 21 is arranged on the outside of the button 2, one end is buckled in the buckle overlap portion 12, and the other end is exposed to the mounting hole 11, and a disassembly activity space 212 is provided between the buckle 21 and the button 2. When the button is damaged and needs to be replaced, since some parts of the buckle are exposed to the mounting hole, the operator can press this part, and further, since there is a disassembly activity space between the buckle and the button, under the action of the pressing force, the buckle can move away from the buckle overlap portion, so that the button and the housing are unlocked, and the button can be removed and installed in another button without using any tools, and the process is very convenient.

[0024] As a further solution of the utility model: the buckle 21 is provided with an avoidance slope 211, and the avoidance slope 211 guides the buckle 21 to avoid obstacles and enter into connection with the buckle overlap portion 12 when the button 2 is installed.
