An installation hole 401 is formed on one side of the housing to install a side-pull waterproof button. When the side-pull waterproof button is inserted and pulled out, it correspondingly controls the contact of the tactile switch 20 (that is Figure 1 the protrusion on the top of the tactile switch 20 in the figure) to pop up and press down (press down when inserted and pop up when pulled out), so that the tactile switch 20 outputs corresponding key signals. The side-pull waterproof button is waterproof protected when inserted and pulled out.

[0027] It should be understood that the main board 10 is fixed inside the housing by screwing with screws 30, and the tactile switch 20 is surface-mounted and welded on the main board. A key circuit or a control circuit is also provided on the main board, which is composed of a plurality of PCBA components (i.e., electronic components welded on the main board) for realizing key functions. The key signal output by the tactile switch 20 can be input into the key circuit for corresponding processing (such as filtering and noise reduction), and then transmitted to the control circuit; or directly input into the control circuit to realize the corresponding key function. In specific implementation, the tactile switch 20 can be set to other functions that require quick response according to needs, and its function is not limited here.

[0028] Such as Figure 1 shown, the side-pull waterproof button includes an outer key component, a key body 501, a waterproof component 502 and an inner key component; the inner key component is fixed at the installation hole 401 on the inner side of the housing. One end of the key body 501 is arranged at one end of the key body component, and the other end of the key body 501 is sleeved with the waterproof component 502, passes through the installation hole 401 and then inserts into the inner key component; when inserted, the other end of the key body 501 presses the contact of the tactile switch 20, and when pulled out, the other end of the key body releases the contact, and the inner key component limits the movement of the key body 501 and guides and positions it. The waterproof component 502 is a waterproof sealing ring, and it is waterproof by the extrusion principle of interference fit between it and the through hole 520 on the mounting seat 513, and further dustproof by the isolation and block of the outer key component.

[0029] The key body is inserted and pulled out through the outer key component, and the pressing and releasing operations of the internal tactile switch 20 are controlled by the insertion and pulling out of the key body, so as to realize the corresponding key function. Using the insertion and pulling out of the key body to replace the existing keycap pressing function, the operation is more convenient and fast, and the insertion and pulling out states of the key body are clear at a glance, which is convenient for users to quickly understand whether the key operation is completed; through the waterproof function of the waterproof component and the isolation and block of the outer key component, the waterproof and dustproof requirements in the use environment are met.

[0030] Please refer to together Figure 3 、Figure 4 and Figure 5 , the external key component includes a side keycap 503 and a lanyard 504. The middle of the inner cover 505 of the side keycap 503 (equivalent to one end of the key body component) fixes one end of the key body 501, and the lanyard 504 is fixed to the outside of the cap top 506 of the side keycap 503. The side keycap 503 is used to cover the mounting hole 401 on the housing for dust prevention. The user drives the side keycap 503 by pulling the lanyard 504 outwards, so that the key body 501 is pulled out synchronously.

[0031] In case of an emergency, just pulling the lanyard 504 can pull out the key body 501 to trigger the button function of the touch switch 20; the user can even operate with one hand, and grasping the lanyard and shaking the electronic device can also achieve the effect of pulling out the key body 501, and the limit bracket in the inner key component can prevent the key body 501 from being completely pulled out. The insertion and extraction states of the side keycap 503 and the key body are very obvious, which is convenient for users to quickly understand whether the button operation is completed, and is suitable for the elderly or children.

[0032] Preferably, the external key component further includes two positioning posts 507. One end of the two positioning posts 507 is fixed on the inner cover 505 of the side keycap 503 and is located on both sides of one end of the key body 501. The other end of the two positioning posts 507 is inserted into the inner key component to play a role of guiding and positioning.

[0033] The material of the side keycap 503 is preferably plastic, and its shape can be designed according to the shape of the electronic device housing and its installation position on the housing. For example Figure 2 shown in Figure, it is installed at a corner of the electronic device housing, and this corner is an arc surface. The side keycap 503 is designed as an arc surface matching this corner; if it is installed on a straight side of the electronic device housing and the side is a straight line, then the side keycap 503 is designed as a straight surface matching this side, mainly to be able to cover the mounting hole 401 on the housing. The cap top 506 of the side keycap 503 can be set as a lanyard hole structure. For example, there are two hollow hanging holes 523 on the cap top 506. Thread the lanyard through the hanging holes 523 on the cap top 506, which is convenient for threading the lanyard, and the mold ejection is simple. When pulling the lanyard 504 outwards with force, it can trigger the touch switch 20 to realize the corresponding button function.

[0034] In Figure 3 the front structure schematic diagram shown in Figure, the front side of the inner cover 505 is a plane; in Figure 4 the back structure schematic diagram shown in Figure, the back side of the inner cover 505 is a concave surface, leaving space for the lanyard to pass through the hanging hole 523.

[0035] The key body 501 is a stainless steel metal part, and its structure is as shown in Figure 1 or Figure 3As shown, it is similar to a cuboid. At one end where the key body 501 is fixed to the inner cover 505, there are two circles of convex rings. The thicker first convex ring 508 facilitates the fixation of the key body 501 to the inner cover 505, and the thinner second convex ring 509 is used to limit the waterproof part 502. At the other end of the key body 501, there is a semi-convex ring 510. As Figure 5 shown, the thickness of the other end of the key body 501 is smaller than that of one end of the key body 501; a limit hole 511 is opened at the top of one end of the key body 501, and a limit protrusion 512 is provided at the bottom of one end of the key body 501. The limit hole 511 and the limit protrusion 512 cooperate with the inner key assembly to perform movement limitation. All the structures on the key body 501 (including the three convex rings and the limit protrusion 512) are integrally formed, as Figure 6 shown in the sectional view of. The edge of the limit hole 511 is provided with a C angle with a size of 0.1×0.1 mm, which facilitates the positioning post of the limit bracket to be more easily inserted into the limit hole.

[0036] The inner key assembly includes a mounting seat 513 (made of plastic), a limit piece 514 (made of steel, also called a limit steel piece), and a limit bracket 515 (made of plastic); the limit piece 514 is fixedly screwed to two vertical screw holes 516 on one side of the mounting seat 513 through two screws 517 (specifically, a screw hole is provided at each end of the limit piece 514, and the screw 517 passes through the screw hole on the limit piece 514 and is screwed into the vertical screw hole 516); the other end of the key body 501 is inserted into the through hole 520 of the mounting seat 513. A clamping protrusion 518 is provided in the middle of the limit piece 514. The key body 501 presses on the limit piece 514. When the key body 501 is inserted and pulled out, the limit protrusion 512 of the key body 501 moves correspondingly on both sides of the clamping protrusion 518; the limit bracket 515 is fastened and fixed on the key body 501. Two positioning holes are respectively provided on the other side of the mounting seat 513. The other end of the positioning post 507 is inserted into the corresponding positioning hole, and the clearance fit with the positioning hole is 0.05 mm on one side, which plays a role in guiding and positioning the key body 501 and prevents the problem of shaking in the cooperation between the key body and the mounting seat 513.

[0037] Preferably, a limit post 519 is respectively provided inside the two vertical screw holes 516, and a limit hole (with a smaller hole diameter than the screw hole) is respectively provided on both sides of the clamping protrusion 518 of the limit piece 514. When the limit piece 514 is placed on the vertical screw hole 516, the limit post 519 is inserted into the corresponding limit hole, and the clearance fit is 0.05 mm on one side, which can prevent the limit piece 514 from moving.

[0038] Please refer to Figure 6, the top of the limit bracket 515 is similar to a convex shape. A clamping post 521 is provided at the bottom of the top of the bracket. The clamping post 521 is inserted into the limit hole 511 on the key body 501. The bottoms of the two legs 522 of the limit bracket 515 are arc-shaped and bent inward, so that a snap-fit structure can be formed and snapped onto the key body 501.

[0039] Please refer to Figure 7 and Figure 8 . During normal assembly, after the other end of the key body 501 is sleeved with the waterproof member 502, it is inserted into the through hole 520 of the mounting seat 513 from the mounting hole on the side of the housing until it reaches the through hole 520. The limit bracket 515 is snapped onto the key body 501. At this time, the positioning protrusion 518 on the limit piece 514 is located inside the limit protrusion 512 on the key body 501. The other end of the key body 501 presses the contact of the touch switch 20. The clamping post 521 on the limit bracket 515 is inserted into the limit hole 511 of the key body 501, and combined with the snap-fit structure of the legs 522 on the limit bracket 515, it is ensured that the key body 501 will not loosen.

[0040] When pulling the lanyard 504 outward with force, the positioning protrusion 518 is deformed due to the pulling force and slides to the outside of the limit protrusion 512. The legs 522 of the limit bracket 515 are stuck on the through hole 520 of the mounting seat 513, preventing the key body 501 from being completely pulled out. After the key body 501 is pulled out a preset distance, the other end of the key body 501 releases the contact of the touch switch 20, and the contact of the touch switch 20 bounces up to achieve the corresponding key function.

[0041] In summary, the side-pull waterproof key and the electronic device of the present invention have a simple structure of the side-pull waterproof key and are easy to install and operate; only by pulling the lanyard can the key body be pulled out to trigger the key function of the touch switch, and it can be operated with one hand. Moreover, the insertion and extraction states of the side key cap and the key body are very obvious, which is convenient for users to quickly understand whether the key operation is completed and is suitable for use by the elderly or children.

[0042] At the same time, each component is manufactured separately, and the production and processing are simple. It is easy to control and manage a single component, improving the yield rate of the production of waterproof keys; since each component is manufactured separately, the size of the waterproof seal ring can be unified, so as to achieve the purpose of unified design specifications, reducing the mold opening cost and the manufacturing cost of the waterproof key; it has an IP67-level waterproof function, which has a strong protective effect on the key. The installation and disassembly are convenient. To disassemble, only need to remove the limit bracket of the buckle, and then the key body can be taken out from the side of the housing, directly reducing the manufacturing cost and the maintenance cost, improving the production efficiency, and having strong practicability. It can be widely used in the structural design of similar keys for various electronic devices.

[0043] It should be understood that the application of the present utility model is not limited to the above examples. For those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations shall fall within the protection scope of the appended claims of the present utility model.
