The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

An embodiment of the present invention provides a protection structure of a multi-way key switch, as shown in fig. 1 and 2, the protection structure of the multi-way key switch includes a housing 1, a multi-way key switch body 2, a key cap 3, and a protection member 4, wherein the housing 1 is provided with a mounting hole 11 for conveniently mounting the key cap 3. As shown in fig. 3, the multi-directional key switch body 2 is provided in the housing 1 at a position corresponding to the mounting hole 11. It should be noted that the multi-directional key switch 100 generally has a circuit board 6, wherein the circuit board 6 is disposed in the housing 1, and the multi-directional key switch body 2 is electrically connected to the circuit board 6.

As shown in fig. 2 to 4, the key cap 3 includes a rod portion 31 and a cap portion 32 connected to each other, wherein the rod portion 31 passes through the mounting hole 11 and is connected to the multi-directional key switch body 2, and the cap portion 32 is exposed out of the housing 1. Specifically, the bottom end of the rod portion 31 is provided with an insertion groove (not shown), and the top end of the multi-directional key switch body 2 is inserted into the insertion groove, so as to connect the keycap 3 and the multi-directional key switch body 2. The keycap 3 is mushroom-shaped in overall appearance.

As shown in fig. 2 and 3, the protector 4 includes a protector 41; as shown in fig. 5 to 7, the guard 4 is fitted on the rod 31, and when the guard 4 swings in multiple directions together with the key top 3, the outer wall of the guard 41 can always abut against the hole wall of the mounting hole 11 to close the mounting hole 11. It should be noted that the multi-directional swing described herein includes vertical movement of the key cap 3 when the key cap 3 is pressed vertically.

It will be appreciated that the shielding member 4 is inserted into the mounting hole 11 and directly engaged with the mounting hole 11, and the cap portion 32 of the key cap 3 can still abut against the outer wall of the housing 1 during multi-directional swinging. In the initial state (i.e., the state where the key top 3 is not pressed), the guard 4 may be completely located in the mounting hole 11, or may not be completely located in the mounting hole 11. In short, in any state, it is only necessary that at least a part of the guard portion 41 of the guard 4 is always located in the mounting hole 11 so as to ensure that the outer wall of the guard portion 41 abuts against the hole wall of the mounting hole 11. In practice, however, there may be a small gap between the outer wall of the protective part 41 and the wall of the mounting hole 11, i.e. there may be a situation where the fitting is not completely tight.

Compared with the prior art, the protection structure of the multidirectional key switch at least has the following beneficial effects: in any case, the protective piece 4 can largely fill the gap between the rod 31 of the key cap 3 and the housing 1 through the protective piece 4 by the cooperation between the protective piece 4 and the hole wall of the mounting hole 11 at the position corresponding to the mounting hole 11 through the additional protective piece 4, so as to prevent impurities such as dust and water from entering the housing 1 through the mounting hole 11, thereby ensuring that the multidirectional key switch 100 has good protection effects such as water resistance and dust resistance.

In addition, although the rod part 31 of the key cap 3 is sleeved with the protection piece 4, the protection piece 4 does not prevent the cap part 32 of the key cap 3 from normally contacting with the outer wall of the shell 1 during multidirectional swinging, so that the multidirectional key switch 100 is beneficial to ensuring good hand feeling.

In order to make the technical solution of the present invention better understood by those skilled in the art, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to fig. 1 to 7.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 2, fig. 3 and fig. 5, the outer wall surface of the protection portion 41 is a conical surface 411, and the hole wall of the mounting hole 11 of the housing 1 is provided with a conical surface 111, wherein the conical surface 111 is adapted to the outer wall surface of the protection portion 41. Specifically, in the present embodiment, the protection portion 41 of the protection member 4 has a structure that the top is smaller than the bottom, that is, a structure that is narrow at the top and wide at the bottom. Correspondingly, the diameter of the mounting hole 11 gradually increases toward the inside of the housing 1. Therefore, the size of the mounting hole 11 formed in the shell 1 can be ensured to be as small as possible, and better protection is facilitated; secondly, when the key cap 3 swings in multiple directions, the protection piece 4 can smoothly swing along with the key cap 3.

Of course, the outer wall surface of the protector 41 may be a spherical surface, and correspondingly, the hole wall of the mounting hole 11 may be a spherical surface matching the outer wall surface of the protector 41.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 5 to 7, a portion of the protection portion 41 of the protection member 4 is disposed in the mounting hole 11, and a portion of the protection portion passes through the mounting hole 11 and is exposed to the housing 1. In this way, in the initial state, as shown in fig. 6, the top of the protection member 4 protrudes from the mounting hole 11 to the outside of the housing 1, and the gap between the rod portion 31 and the housing 1 can be filled to a large extent, so that the entry of impurities such as dust and water into the housing 1 through the gap can be further reduced.

When the key top 3 is laterally pressed, as shown in fig. 7, the protection part 41 is partially exposed from the housing 1, so that a part of the conical surface 411 of the protection part 41 of the protection member 4 can be further ensured to be always accommodated in the housing 1, and thus, even when the key top is laterally pressed for use, impurities can be still prevented from entering the housing 1, and a good protection effect can be achieved.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 5 to 7, in a length direction of the rod portion 31 of the key cap 3 (i.e. a direction in which the key cap 3 is pressed vertically), a distance between the bottom of the protection member 4 and the multi-directional key switch body 2 is smaller than a distance between the bottom of the rod portion 31 and the multi-directional key switch body 2. In short, the protector 4 is closer to the end face (or the circuit board 6) of the multi-directional key switch body 2 in the vertical direction. It will be appreciated that the height of the guard 4 is greater than the length of the stem portion 31, whereby the guard 4 may cover the entire stem portion 31.

It is also understood that, as shown in fig. 6, when the key cap 3 is pressed vertically, the bottom of the protection member 4 can contact with the end surface of the multi-directional key switch body 2 first because the protection member 4 is closer to the circuit board 6, so as to reduce the pressing stroke of the key cap 3, and the multi-directional key switch body 2 will not be damaged due to the excessive pressing stroke of the key cap 3 when the key cap 3 falls.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 3, 5 to 7, the bottom of the protection member 4 is provided with a slope 431, wherein the slope 431 is inclined downward from the hole wall of the installation hole 11 to the hole center. Thus, as shown in fig. 7, during the process of laterally pressing the key cap 3, the inclined surface 431 may abut against the end surface of the multi-directional key switch body 2 and/or a portion of the key cap 3 (i.e., a main body portion of the key cap 3) radially extending out of the mounting hole 11 may abut against the outer side of the housing 1, so as to prevent the key cap 3 from being further pressed downward, thereby further ensuring that the multi-directional key switch 100 is not damaged during the falling process.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 2, 5 to 7, an arc-shaped groove 12 is concavely provided on an outer wall of the housing 1 at the periphery of the mounting hole 11, and the arc-shaped groove 12 is inclined toward the center of the mounting hole 11, that is, relative to the mounting hole 11, the outer side is higher and the inner side is lower. The portion of the bottom of the cap 32 protruding radially from the mounting hole 11 is concave-convex fitted to the arc-shaped groove 12. In the present embodiment in particular, as shown in fig. 4 to 7, the bottom of the cap 32 is provided with an arc-shaped surface 323 along a portion thereof radially protruding out of the mounting hole 11, and it is understood that the arc-shaped surface 323 is fitted with the arc-shaped groove 12.

Understandably, as shown in fig. 7, in the process of laterally pressing the keycap 3, the main body of the keycap 3 can be abutted against the outer side of the casing 1, so as to ensure that the keycap 3 is further pressed, which is beneficial to improving the service life of the multi-directional key switch 100 and ensuring the use hand feeling of the multi-directional key switch 100.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 2, 4, 5 to 7, the protection component 4 is provided with an insertion hole 44 along a central line thereof, wherein the insertion hole 44 is mainly used for inserting the rod portion 31 of the keycap 3. As shown in fig. 2, the cap portion 32 of the key cap 3 is formed with a first connecting hole 3211 at the periphery of the insertion hole 44, and the top portion of the protection member 4 is formed with a second connecting hole 45, as shown in fig. 5 to 7, the protection member 4 is sequentially inserted into the first connecting hole 3211 and the second connecting hole 45 to be sleeved on the rod portion 31 of the key cap 3.

Specifically, in the embodiment, as shown in fig. 2, a mounting groove 322 is formed at the top of the cap part 32 of the key cap 3, and the protection structure of the multi-directional key switch further includes a cap 33, wherein the cap 33 is accommodated in the mounting groove 322 and is adapted to the mounting groove 322. In addition, the first connection hole 3211 is opened at the bottom of the mounting groove 322. It can be understood that the cap 33 is arranged in the mounting groove 322, so that the cap 33 covers the connecting piece 5, thereby achieving the cloaking effect; secondly, the cap 33 can prevent impurities such as dust, water and the like from entering the housing 1 through the first connecting hole 3211 and the second connecting hole 45 to play a role of protection, and the protection piece 4 can be reliably sleeved on the rod part 31; thirdly, when the vertical pressing is carried out, the use hand feeling during the vertical pressing can be ensured by the contact between the cap cover 33 and the groove bottom of the mounting groove 322; fourthly, the installation groove 322 is opened, and the cap 33 is arranged in the installation groove 322, which is beneficial to reducing the thickness of the multi-direction key switch 100.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 2, 5 to 7, the second connecting hole 45 on the protection component 4 is a countersunk hole, wherein the countersunk hole includes a countersunk portion (not shown) and a connecting portion (not shown), and an inner wall of the connecting portion is provided with an internal thread. In short, in the present embodiment, the second connection hole 45 is a countersunk threaded hole.

As shown in fig. 4 to 7, a boss 321 is protruded from the bottom of the cap 32, wherein the boss 321 is accommodated in the countersunk portion of the countersunk hole, and the boss 321 is provided with a first connection hole 3211. As can be understood, by aligning the boss 321 with the counterbore, positioning between the protection member 4 and the key cap 3 can be realized, which is further beneficial to ensuring that the protection member 4 can be accurately sleeved on the rod portion 31 of the key cap 3; and secondly, the socket joint of the protection part 4 and the rod part 31 is realized, and simultaneously, the structure of the multi-direction key switch 100 is more compact, so that the thickness of the multi-direction key switch is reduced.

Specifically, in the present embodiment, as shown in fig. 2 and 3, the protector 4 actually further includes the pressing portion 42 and the abutting portion 43, and the pressing portion 42, the protector 41, and the abutting portion 43 are connected in this order from top to bottom. Preferably, the three can be integrally formed. As shown in fig. 2 and 5 to 7, the pressing portion 42 is a circular truncated cone disposed at the top end of the protecting portion 41, a countersunk portion of the second connecting hole 45 (i.e., a countersunk hole) is formed on the pressing portion 42, and the connecting portion is formed on the protecting portion 41, i.e., the second connecting hole 45 is provided with an internal thread on a hole wall corresponding to the protecting portion 41. In the initial state, the pressing portion 42 is normally exposed to the mounting hole 11, so that the reliability of sealing the mounting hole 11 is further improved.
