The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The technical solution of the present invention will be described in detail with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 1a and 1b are schematic diagrams illustrating an operation principle of a key body pressed down according to an embodiment of the present invention; fig. 2a and 2b are schematic diagrams illustrating an operation principle of the key body being pressed down according to an embodiment of the present invention; fig. 3 is an explosion diagram of the key-type smart wall switch according to an embodiment of the present invention; fig. 4 is a schematic cross-sectional view of a push-button type smart wall switch according to an embodiment of the present invention.

Referring to fig. 1a, fig. 1b to fig. 4, the key-type intelligent wall switch includes a bottom case 6, a circuit board structure, a key body 2, a middle case 3, and a first elastic component 1.

The middle shell 3 covers the bottom shell 6, specifically, an opening may be formed on a first side of the bottom shell 6, the middle shell 3 may cover the opening, and an internal space may be formed between the middle shell 3 and the bottom shell 6; the circuit board structure is arranged in the inner space.

The key body 2 is connected to a side of the middle housing 3 facing away from the inner space, which may be, for example, the upper side of the middle housing 3 shown in fig. 1a, 1b, 2a, 2b and 4; a switch device 401 is arranged on one side of the circuit board structure opposite to the middle shell 3; the first elastic member 1 may pass through the middle case 3, the first elastic member 1 is located between the key body 2 and the controlled portion of the switch device 401 along the pressing direction of the key body 2, the first elastic member 1 may not pass through the middle case 3, for example, a corresponding extension portion may be provided on the key body 2, and the extension portion may pass through the middle case 3 to be abutted with the first elastic member 1.

In an example, two ends of the first elastic component 1 may be respectively used for abutting against or connecting the key body 2 and the switch device 401. The abutment therein is understood to be: the two ends of the first elastic component 1 can keep contact with the key body 2 and the switch device 401, and when the key body 2 is not pressed, the three components do not move.

In another example, the first elastic member 1 may be integrated with the switching device 401.

In addition, the bottom shell can be further provided with cable mounting holes, the cable mounting holes can be used for externally accessing cables, for example, firewire cables can be accessed, and the number of the cable mounting holes can be at least two.

The switching device 401 may have a first state and a second state, where the first state is a state when the controlled portion of the switching device 401 is not touched, and the second state is a state when the controlled portion of the switching device 401 is touched, and meanwhile, in the first state, a circuit controlled by the switching device may be turned on, and in the second state, a circuit controlled by the switching device may be turned off, and in other examples, the circuit controlled by the switching device may also be turned off in the first state, and the circuit controlled by the switching device may be turned on in the second state.

Depending on the switching device 401, the manner of being triggered may be different, for example, the controlled portion may be controlled to move telescopically relative to the main body of the switching device 401, or may be controlled to swing or rotate, which, in any way, does not depart from the description of the embodiment.

When the external force applied to the controlled part does not exceed the strength of the switching point, the switch device 401 is in the first state; when the external force applied to the controlled part exceeds the strength of the switching point, the switch device is in the second state; for example, the controlled portion may be compressed into the body of the access switching device 401 when entering the second state.

Referring to fig. 1a and 1b, and fig. 2a and 2b, the first elastic component 1 can be pressed by the key body 2 and the switch device 401 to generate a first compression deformation, and generate an acting force to overcome the first compression deformation, so that: the current external force of the first elastic component acting on the controlled part of the switch device is increased;

when the current external force exceeds the force of the switching point, the switch device is changed from the first state to the second state, and the controlled part of the switch device is triggered.

The switching point force may be a fixed force or a variable force, and as long as the switching of the switch device between the first state and the second state is performed due to the variation degree of the applied current external force, it can be understood that the above description about the switching point force is not broken away.

When the key body 2 is pressed down, the first elastic component 1 can be finally pressed and touches the switch device 401 to be switched on or off under the pushing of the key body 2, and the first elastic component 1 can also generate a first compression deformation under the extrusion of the key body 2 and the switch device 401 and generate an acting force for overcoming the first compression deformation. The first elastic component 1 is first compressed and deformed, so that the switch device 401 is triggered.

The first compression deformation is a deformation that is reduced in size along the direction of pressing the switch device 401 due to pressing, and the direction of pressing the switch device 401 is the same as the direction of pressing the switch device, and further, as shown in the figure as an example, the length of the first elastic member 1 in the direction can be changed from L to Δ X, where Δ X is a positive number, due to the first compression deformation.

Besides the deformation in the compression direction, deformation in other directions may also be caused, for example, the first elastic component may also be subjected to expansion deformation along a transverse direction perpendicular to the compression direction, as long as the first elastic component 1 is subjected to compression deformation in the extrusion direction, no matter whether other deformation is caused or not, or the deformation manner is not deviated from the description of the embodiment.

The switching device 401 referred to above may be a microswitch, and in other embodiments it is not excluded to use other existing or improved devices for controlling the switching of the lines. The number of the switching devices 401 may be the same as the key body 2.

In one embodiment, when the acting force of pressing the key body 2 disappears, the first elastic component 1 can be restored to the original form from the first compression deformation, so that the current external force is reduced;

when the current external force is smaller than the force of the switching point, the switch device 401 is restored from the second state to the first state, and the controlled part of the switch device 401 is restored to the position before being touched.

Furthermore, the first elastic component 1 can be restored to the shape and position of the key body 2 when not pressed along with the restoration of the switch device 401, so that the key body 2 is restored and lifted.

In addition, the present embodiment does not exclude the possibility that the first elastic member 1 cannot restore the key body 2 to the original position by the self restoring deformation force, and further, in an example, the key body 2 may be restored and lifted by the action of other members, or restored and lifted by the combined action of the first elastic member 1 and other members, where the other members may be, for example, a second elastic member as described below, or a third elastic member disposed in the middle case, such as a spring plate or a spring.

Because the part of locating between button body and the switching device is the first elastomeric element that has deformability, this first elastomeric element can be in the button body with the extrusion of switching device can take place first compression deformation, and then, when the button body is controlled and takes place the motion, the motion that the user experienced has included the stroke that the switching device was touched, has still included the stroke that the deformation of first elastomeric element brought, and it can make the user experience pressing of button body, improves and presses and feels, has improved user's use experience.

Simultaneously, because first elastic component can also produce the effort of resumeing the deformation when taking place deformation, it can make the switch body can produce a resistance of antagonizing the user and pressing, and based on this, the user can produce and is close to the pressing of mechanical button and feel, has further improved user's use experience.

When specifically using, use first elastic component as the silica gel guide pillar, and the switching device is micro-gap switch as an example:

when pressing the button body, first compression deformation takes place at first for the silica gel guide pillar, treats deformation when certain degree, presses and triggers micro-gap switch, and micro-gap switch can move this moment. In the rebound process, the key body can still rebound by the elasticity of the silica gel column, and the silica gel column returns to the initial form.

In a specific implementation process, the movement of the key body 2 when pressed down may be controlled to rotate or swing as shown in fig. 1a and 1b, or may be controlled to move linearly as a whole as shown in fig. 2a and 2 b. No matter what kind of movement, the above effects can be generated by the compression of the key body 1, so the description of the present embodiment is not departed from.

In addition, the number of the first elastic components 1 may be determined according to the number of the key bodies 2, for example, an elastic structural component may be provided for each key body 2, and in other examples, all the first elastic components 1 may be designed as a whole to reduce the number of parts; as can be seen, the first compression set referred to above may also mean that a part of the first elastic member 1 is compressed.

Fig. 5 is a schematic structural diagram of the first elastic member according to an embodiment of the present invention.

In order to be suitable for the first elastic component to pass through, the middle shell 3 may be provided with a through hole for the first elastic component 1 to pass through, and further, referring to fig. 5, a key-side limiting portion 101 and a circuit-side limiting portion 102 may be provided outside the first elastic component 1.

The key side limiting part 101 is located on one side of the through hole close to the key body 2 to limit the first elastic component 1 from moving relative to the middle shell 3 in a direction away from the key body 2;

the circuit side limiting portion 102 is located on a side of the through hole close to the circuit board structure, and may specifically refer to a side facing the control board 4, so as to limit the movement of the first elastic member 1 relative to the middle shell 3 in a direction away from the circuit board structure.

In addition, the key-side stopper 101, the circuit-side stopper 102 and the first elastic member 1 may be made of the same material, and may be integrally formed, which may be applied to the scheme that the first elastic member is a silicone guide pillar, and meanwhile, the present embodiment does not exclude the means of using different materials and/or non-integrally formed.

Through above spacing portion, can realize spacing to first elastic component 1, avoid it to break away from its position that produces the effect, for example first elastic component 1 of silica gel guide pillar can be installed at the mesochite through above spacing portion, and the distance can be suitable for realizing the required motion that takes place of first elastic component 1 between two above spacing portions, and then, this first elastic component 1 is mobilizable for the mesochite.

The circuit-side stopper 102 may have a ring-shaped structure, or may include a plurality of stopper units distributed annularly, and similarly, the key-side stopper 101 may have a ring-shaped structure, or may include a plurality of stopper units distributed annularly.

In this embodiment, any material and/or shape that can generate the above first compression deformation and generate an acting force to overcome the deformation when deforming does not depart from the description of this embodiment, regardless of the relationship between the deformation and the acting force.

In a specific implementation process, the first elastic component includes any one of the following components: spring, shell fragment, elasticity bubble cotton, silica gel guide pillar. In the embodiments shown in fig. 3 to 5, the silicone guide posts are used as examples for explanation, and the implementation manners of the springs, the elastic pieces, the elastic foam, and the like can be changed with reference to the examples in fig. 3 to 5.

In addition, in a scenario where a plurality of first elastic members are required to be used (for example, a scenario where more than one first elastic member is configured for one key body, and/or a scenario where a plurality of key bodies are provided), in one example, each first elastic member may be the same, and in another example, it is not excluded that some first elastic members are different, where the difference includes that the first elastic members of the same type are used but different specific performance parameters, sizes, and shapes, and also includes that the first elastic members of different types are used.

Referring to fig. 6a, 6b to 9, in one embodiment, a protrusion 301 is disposed on one side of the middle shell 3 connected to the key body, the key body 2 can swing around the protrusion 301 as a fulcrum, the swing can also be regarded as a lever motion or a pivot motion, and the first elastic component 1 is disposed on one side of the protrusion along a reference direction.

The reference direction is a direction from the non-pressing end to the pressing end of the key body and the middle shell, which may be a left-right direction as shown in fig. 6a and 6 b. The pressing end can be understood as an end adapted to be controlled to be pressed, such as a right end shown in fig. 6a and 6b, and the non-pressing end can be understood as an end away from the pressing end, such as a left end shown in fig. 6a and 6 b.

The position of the first elastic component 1 is understood to be deviated from the fulcrum position of the swing, which enables the swing to press the first elastic component 1, so that the first elastic component is subjected to the first compression deformation and the position change.

The key body 2 can swing around a first rotating direction when being pressed down and extrude the first elastic component 1; the first elastic component 1 can push the key body 2 to swing around the second rotation direction when recovering the shape and the position. The first and second rotational directions may be opposite directions.
