Detailed Description

The switch module of the embodiment of the invention can be applied to any pressing type input device (such as a mouse, a keyboard and the like) or integrated with any convenient electronic device (such as a key of a portable electronic device and the like) so as to adjust the strength required by pressing operation and provide the requirement of users for using different strengths to operate. The structure and operation of the elements of the switch module according to the embodiments of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a schematic diagram of an input device including a switch module according to an embodiment of the invention. In this embodiment, the switch module 1 may be disposed at a suitable position inside the input device 400, such as a mouse, to correspond to and couple with the mouse buttons. When the user presses a mouse button (for example, the arrow in fig. 1 is used as a pressing position), the switch module 1 can be driven together to input a signal.

Please refer to fig. 2A to 2D, which are schematic diagrams illustrating the operation of the switch module according to an embodiment of the invention. As shown in fig. 2A to 2D, the switch module 1 of the embodiment of the invention includes a base 100, a switch mechanism 200 and a magnetic force adjusting unit 300. The switch mechanism 200 is disposed on the base 100, the switch mechanism 200 includes a first magnetic component, and the switch mechanism 200 can be driven by an external force and coupled with the first magnetic component. The magnetic force adjusting unit 300 is disposed on the base 100, and the magnetic force adjusting unit 300 has at least one second magnetic attraction component, and the magnetic force adjusting unit 300 is configured to adjust a magnetic attraction force with the switch mechanism 200, where the magnetic attraction force is related to a resistance when the switch mechanism 200 is driven (as shown in fig. 2A).

Specifically, the magnetic force adjustment unit 300 may be directly implemented with a magnet, and the switching mechanism 200 may be implemented with a magnet or a material that can be attracted to a magnet. When the magnet of the magnetic force adjusting unit 300 is far away from the base 100, the magnetic attraction force between the magnetic force adjusting unit 300 and the switch mechanism 200 is reduced, and at this time, the magnetic attraction force required to be opposed when the switch mechanism 200 is driven is reduced, that is, the resistance encountered by pressing the switch mechanism 200 is also smaller, as shown in fig. 2B. In addition, as the number of magnets as the magnetic force adjusting unit 300 increases, the magnetic attraction force between the magnetic force adjusting unit 300 and the switching mechanism 200 increases, and at this time, the magnetic attraction force that needs to be opposed when the switching mechanism 200 is driven increases, that is, the resistance encountered by pressing the switching mechanism 200 is large, as shown in fig. 2C. Alternatively, the magnetic force adjusting unit 300 may be implemented by an electromagnet 340, and in the case that the relative position between the electromagnet 340 and the switch mechanism 200 is not changed, the magnitude of the magnetic attraction force with the switch mechanism 200 may be directly adjusted to adjust the magnitude of the force required to press the switch mechanism 200, as shown in fig. 2D.

Fig. 3 is a schematic diagram illustrating an operation of a switch module according to another embodiment of the invention. As shown in fig. 3, unlike the embodiment of fig. 2A to 2D, the direction in which the switch mechanism 200 of the switch module 1 of the present embodiment presses is perpendicular to the direction of the magnetic attraction force, and the embodiment of fig. 2A to 2D is parallel to the direction in which the switch mechanism 200 presses. In the switch module 1 in fig. 3, the switch mechanism 200 may include a first magnetic component 210, and the magnetic force adjusting unit 300 may include a second magnetic component 310 and a carrier 320. The second magnetic member 310 in the magnetic force adjustment unit 300 is disposed on the carrier 320, and the first magnetic member 210 in the switching mechanism 200 is disposed opposite to the second magnetic member 310 in the magnetic force adjustment unit 300.

In fig. 3, the distance between the magnetic force adjusting unit 300 and the switching mechanism 200 may be adjusted such that the distance between the first magnetic attraction member 210 and the second magnetic attraction member 310 is changed to adjust the magnitude of the magnetic attraction force. Alternatively, the number of magnets acting between the first magnetic member 210 and the second magnetic member 310 may be changed by the relative movement of the magnetic force adjustment unit 300 and the switch mechanism 200. Alternatively, the second magnetic member 310 and the first magnetic member 210 may be replaced by the relative movement of the magnetic force adjustment unit 300 and the switch mechanism 200. Alternatively, any combination of the three adjustment modes may be used. That is, the movement of the magnetic force adjusting unit 300 relative to the switch mechanism 200 includes at least one of the following: (1) a distance from the second magnetic attraction member 310 that acts on the first magnetic attraction member 210 of the switching mechanism 200 changes, (2) the number of the second magnetic attraction members 310 that acts on the first magnetic attraction member 210 of the switching mechanism 200 changes, and (3) a replacement of a different second magnetic attraction member 310 acts on the first magnetic attraction member 210 of the switching mechanism 200.

Next, referring to fig. 4, an activity diagram of a magnetic force adjusting unit according to another embodiment is shown. As shown in fig. 4, the magnetic force adjusting unit 300 disposed on the base 100 can move relative to the switch mechanism 200, for example, the magnetic force adjusting unit 300 can move back and forth, up and down, and left and right relative to the switch mechanism 200, i.e. corresponding to the Y direction, the Z direction, and the X direction in fig. 4, thereby adjusting the magnitude of the magnetic force between the first magnetic attraction component 210 of the switch mechanism 200 and the second magnetic attraction component 310 of the magnetic force adjusting unit 300. Alternatively, the magnetic force adjusting unit 300 may be rotated on the housing 100 to change the magnitude of the magnetic attraction force between the second magnetic attraction member 310 and the first magnetic attraction member 210 of the switching mechanism 200.

In an embodiment, the magnetic force adjustment unit 300 may be moved from a first position to a second, different position relative to the switch mechanism 200, thereby changing the magnetic attraction between the first magnetic attraction member 210 and the second magnetic attraction member 310. In another embodiment, the distance between the magnetic force adjusting unit 300 and the switch mechanism 200 is unchanged, but the magnetic force adjusting unit 300 is rotated from the first position to the second position, and the magnetic attraction force between the first magnetic attraction component 210 and the second magnetic attraction component 310 is changed by adjusting the relative position relationship between the magnetic force adjusting unit 300 and the switch mechanism 200.

It will be understood that, although the terms "first," "second," "third," etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a "first element," "component," "region," "layer," or "section" discussed below could be termed a second element, component, region, layer, or section without departing from the teachings herein.

Referring to fig. 5A to 5B, fig. 5A is a schematic diagram of the arrangement of the switch mechanism and the magnetic force adjusting unit before the number of the magnetic attraction components is changed, and fig. 5B is a schematic diagram of the arrangement of the switch mechanism and the magnetic force adjusting unit after the number of the magnetic attraction components is changed. The magnetic force adjusting unit 300 may include a third magnetic attraction component 350 disposed on the switch mechanism 200, and a predetermined distance is provided between the third magnetic attraction component 350 and the first magnetic attraction component 210 on the switch mechanism 200, as shown in fig. 5A, where the magnetic force adjusting unit 300 is located at a first position L1 relative to the switch mechanism 200, and the magnitude of the magnetic attraction force felt when the switch mechanism 200 is pressed depends on the magnitude of the magnetic attraction force between the first magnetic attraction component 210 and the third magnetic attraction component 350.

Specifically, the switching mechanism 200 may include a cover 220, and the cover 220 may have a corresponding structure to simultaneously dispose the third magnetic component 350 and the first magnetic component 210 in the magnetic force adjusting unit 300 on the switching mechanism 200, as shown in fig. 5A, but not limited thereto. When the carrier 320 of the magnetic force adjusting unit 300 moves from the first position L1 to the second position L2 as shown in fig. 5B relative to the switch mechanism 200, the distance between the second magnetic attraction member 310 disposed on the carrier 320 and the third magnetic attraction member 350 disposed on the switch mechanism 200 may change, even the two may contact, and the number of magnets acting on the first magnetic attraction member 210 is the second magnetic attraction member 310 and the third magnetic attraction member 350, so that the magnetic attraction force between the magnetic force adjusting unit 300 and the switch mechanism 200 increases, and the force required for pressing the switch mechanism 200 increases as shown in fig. 5B.

Referring to fig. 6A and 6B, fig. 6A is a schematic diagram before the distance between the switch mechanism and the magnetic force adjusting unit is changed, and fig. 6B is a schematic diagram after the distance between the switch mechanism and the magnetic force adjusting unit is changed. As shown in fig. 6A, the magnetic force adjusting unit 300 disposed on the base 100 can move back and forth relative to the switch mechanism 200, for example, the magnetic force adjusting unit 300 is located at the first position L1 as shown in fig. 6A before moving, and at this time, the second magnetic component 310 in the magnetic force adjusting unit 300 is further away from the first magnetic component 210 of the switch mechanism 200, and the magnetic attraction between the two components is smaller, i.e. the force required for pressing the switch mechanism 200 is smaller. When the magnetic force adjusting unit 300 moves to the second position L2 (i.e., close to the switching mechanism 200) as shown in fig. 6B along the direction of connecting with the switching mechanism 200, the distance between the magnetic force adjusting unit 300 and the switching mechanism 200 is shortened, and the magnetic attraction between the first magnetic attraction component 210 of the switching mechanism 200 and the second magnetic attraction component 310 of the magnetic force adjusting unit 300 is increased.

Referring next to fig. 7A and 7B, fig. 7A is a first schematic view of a through slot of a base according to an embodiment of the present invention, and fig. 7B is a second schematic view of a through slot of a base according to an embodiment of the present invention. In order to allow the magnetic force adjusting unit 300 to move on the housing 100, a through slot 110 may be provided on the housing 100, and one end of the magnetic force adjusting unit 300 passes through the through slot 110 as shown in fig. 7A. For example, the base 100 may extend from below the switch mechanism 200 toward the position where the magnetic force adjusting unit 300 is located, and the extending direction of the through slot 110 is along the direction of connecting the magnetic force adjusting unit 300 and the switch mechanism 200, such as the Y direction in fig. 7A. Alternatively, the extending direction of the through groove 110 is set along the vertical direction of the connection line between the magnetic force adjusting unit 300 and the switch mechanism 200, for example, the X direction in fig. 7A. It can be seen that the size of the through slot 110 determines the range of the first position L1 and the second position L2 where the magnetic force adjusting unit 300 can move.

Alternatively, the magnetic force adjusting unit 300 may also move up and down relative to the switch mechanism 200, such as in the Z direction in fig. 7A and 7B, to adjust the magnetic force between the first magnetic component 210 of the switch mechanism 200 and the second magnetic component 310 of the magnetic force adjusting unit 300. In addition to the parallel movement of the magnetic force adjusting unit 300 up and down, left and right, and front and back with respect to the switching mechanism 200, as shown in fig. 7B, the through groove 110 provided in the base 100 may be a cylinder having the same size as one end of the magnetic force adjusting unit 300, so that the magnetic force adjusting unit 300 rotates, thereby adjusting the magnetic force between the second magnetic member 310 and the first magnetic member 210 of the switching mechanism 200. In practice, the magnetic force adjusting unit 300 may be movable, rotatable or a combination of movable and rotatable with respect to the through slot 110.

For example, when the magnetic force adjusting unit 300 is located at the first position L1, the second magnetic attraction component 310 is disposed opposite to the first magnetic attraction component 210, and the relative distance therebetween is the shortest, so that the magnetic attraction between the magnetic force adjusting unit 300 and the switch mechanism 200 is the largest and the force required to press the switch mechanism 200 is the largest. When the magnetic force adjusting unit 300 moves up and down or rotates to the second position L2 relative to the switch mechanism 200, the relative positions of the second magnetic component 310 and the first magnetic component 210 are not disposed front to front, and the relative distance therebetween is longer, so that the magnetic attraction between the magnetic force adjusting unit 300 and the switch mechanism 200 is reduced, and the force required to press the switch mechanism 200 is relatively reduced.

It should be noted that the design of the through slot 110 and one end of the magnetic force adjusting unit 300 provided in the base 100 is not limited to the above embodiment, and may be appropriately adjusted according to the size of the space or the degree of fineness of the magnetic force between the first magnetic member 210 of the switch mechanism 200 and the second magnetic member 310 of the magnetic force adjusting unit 300.

Referring next to fig. 8A and 8B, fig. 8A is a schematic diagram before replacing a magnetic component acting between a switch mechanism and a magnetic force adjusting unit according to an embodiment of the invention, and fig. 8B is a schematic diagram after replacing a magnetic component acting between a switch mechanism and a magnetic force adjusting unit according to an embodiment of the invention. In this embodiment, the magnetic force adjusting unit 300 can move left and right (i.e. move in a direction perpendicular to the magnetic attraction force) relative to the switch mechanism 200 to adjust the distance between the second magnetic attraction member 310 of the magnetic force adjusting unit 300 and the first magnetic attraction member 210 of the switch mechanism 200. When the magnetic force adjusting unit 300 is located at the first position L1, the second magnetic component 310 and the first magnetic component 210 are disposed facing each other.

Then, when the magnetic force adjusting unit 300 moves left and right with respect to the switching mechanism 200, the magnetic force adjusting unit 300 moves to the second position L2 with respect to the switching mechanism 200, and the second magnetic attraction member 310 moves from the first position L1 facing the front face of the first magnetic attraction member 210 to the second position L2, that is, the second magnetic attraction member 310 and the first magnetic attraction member 210, which are converted into different magnitudes of magnetic attraction forces, are disposed facing the front face of each other. In this way, the magnitude of the magnetic attraction between the magnetic force adjusting unit 300 and the switch mechanism 200 can be increased or decreased according to the requirement, and the required pressing force can be changed to operate the switch mechanism 200.

In practical applications, as another alternative embodiment shown in fig. 8A and 8B, the same second magnetic component 310 may be kept acting on the first magnetic component 210, and when the magnetic force adjusting unit 300 is located at the first position L1, the relative distance between the second magnetic component 310 and the first magnetic component 210 is the shortest, so that the magnetic attraction between the magnetic force adjusting unit 300 and the switch mechanism 200 is the largest, and the force required to press the switch mechanism 200 is the largest. When the magnetic force adjusting unit 300 moves to the second position L2 relative to the switch mechanism 200, the relative positions of the second magnetic component 310 and the first magnetic component 210 are not disposed in front-to-front direction, and the relative distance therebetween is longer, so that the magnetic attraction between the magnetic force adjusting unit 300 and the switch mechanism 200 is reduced, and the force required to press the switch mechanism 200 is reduced relatively.

Referring to fig. 9A and 9B, fig. 9A is a schematic diagram of the magnetic force adjusting unit according to another embodiment before rotation, and fig. 9B is a schematic diagram of the magnetic force adjusting unit according to the above embodiment after rotation. As shown in fig. 9A, the second magnetic component 310 in the magnetic force adjustment unit 300 may include a plurality of magnets with different sizes, such as a first magnet 360 with a larger size and a second magnet 370 with a smaller size. When the magnetic force adjusting unit 300 is shown in fig. 9A, the second magnet 370 with a smaller size in the second magnetic attraction member 310 acts on the first magnetic attraction member 210 of the switch mechanism 200, that is, the distance between the first magnetic attraction member 210 of the switch mechanism 200 and the first magnet 360 with a larger size in the magnetic force adjusting unit 300 is longer, and the magnetic attraction force is smaller. When the magnetic force adjusting unit 300 rotates as shown in fig. 9B, the first magnet 360 with a larger size in the second magnetic attraction part 310 acts on the first magnetic attraction part 210 of the switch mechanism 200, that is, the distance between the first magnet 360 with a larger size in the magnetic force adjusting unit 300 and the first magnetic attraction part 210 of the switch mechanism 200 is shorter, and the magnetic attraction force is larger.

In practical applications, as another alternative embodiment of fig. 9A and 9B, the second magnetic attraction member 310 in the magnetic force adjustment unit 300 may include a plurality of magnets with different magnitudes of magnetic attraction force, for example, a first magnet 360 with a larger magnetic attraction force and a second magnet 370 with a smaller magnetic attraction force. When the magnetic force adjusting unit 300 is shown in fig. 9A, it may be that the second magnet 370 having a smaller magnetic attraction force in the second magnetic attraction part 310 faces and acts with the first magnetic attraction part 210 of the switching mechanism 200. When the magnetic force adjusting unit 300 rotates as shown in fig. 9B, it may be that the first magnet 360 having a larger magnetic attraction force in the second magnetic attraction part 310 faces and acts with the first magnetic attraction part 210 of the switching mechanism 200 to increase the magnetic attraction force between the magnetic force adjusting unit 300 and the switching mechanism 200, so that the operation resistance of the switching mechanism 200 increases, and the user can operate the switching mechanism 200 with a larger pressing force.

By the foregoing embodiment, the distance between the magnetic force adjusting unit 300 and the magnetic attraction member in the switching mechanism 200 can be changed at the same time, and/or a different magnetic attraction member can be replaced, and the magnetic attraction force between the magnetic force adjusting unit 300 and the switching mechanism 200 can be adjusted as well.

Next, referring to fig. 9C, a schematic diagram of a magnetic component penetrating through a through hole of a magnetic force adjusting unit according to an embodiment of the invention is shown. As shown in fig. 9C, the second magnetic component 310 in the magnetic force adjusting unit 300 may be a single magnetic component, so as to adjust the magnetic attraction force between the magnetic force adjusting unit 300 and the switch mechanism 200 in a rotating manner. For example, a through hole 330 may be formed in the carrier 320 of the magnetic force adjustment unit 300, through which the second magnetic member 310 passes and is disposed on the carrier 320, and two portions of the second magnetic member 310 exposed outside the through hole 330 have different lengths. When the magnetic force adjusting unit 300 rotates, the first magnetic attraction member 210 in the switch mechanism 200 can be faced with portions of different lengths to adjust the magnetic attraction force between the magnetic force adjusting unit 300 and the switch mechanism 200.

Referring to fig. 9A and 9B, the second magnetic member 310 includes a first end and a second end, and when the magnetic force adjusting unit 300 rotates on the base 100, the second magnetic member 300 is changed from a state in which the first end faces the first magnetic member 210 to a state in which the second end faces the first magnetic member 210. In other words, when the magnetic force adjusting unit 300 is located at the first position, the first end is spaced from the first magnetic attraction member 210 by a first distance; when the magnetic force adjusting unit 300 is located at the second position, the second end is spaced apart from the first magnetic attraction member 210 by a second distance. The different ends of the second magnetic attraction component 310 face the first magnetic attraction component 210 to change the magnetic attraction between the second magnetic attraction component 310 and the first magnetic attraction component 210.

Note that, the second magnetic attraction member 310 in the magnetic force adjustment unit 300 and the first magnetic attraction member 210 in the switch mechanism 200 may be adjusted so that the magnet and the material that can be attracted by the magnet interact with each other, in addition to the magnet and the magnet. For example, the second magnetic attraction member 310 in fig. 9C may be a material that can be attracted by a magnet, and the first magnetic attraction member 210 may be a magnet. Alternatively, in fig. 5A to 5B, the magnetic attraction member 350 provided on the switching mechanism 200 in the magnetic force adjustment unit 300 may be a magnet, and the second magnetic attraction member 310 provided on the carrier 320 may be a magnet or a material that can be attracted to the magnet, and the first magnetic attraction member 210 on the switching mechanism 200 may be a magnet or a material that can be attracted to the magnet.

Please refer to fig. 10, which is a schematic diagram of an electromagnet acting with a magnetic attraction component of a switching mechanism according to an embodiment of the present invention. As shown in fig. 10, the second magnetic component 310 of the magnetic force adjusting unit 300 may also be implemented as an electromagnet 340, and the switch module 1 may be implemented by an external current and a coil (not shown in the drawings), so as to directly change the magnetic force between the switch module and the first magnetic component 210 of the switch mechanism 200.

Referring to fig. 1, 2A and 3, in the present embodiment, the input device 400 is a mouse, and in actual operation, the input device 400 may be a keyboard, etc., but not limited thereto. The input device 400 is provided with two keys 410 (left and right keys of the mouse in this embodiment), and an abutment post 411 is provided below each key 410, the abutment post 411 facing the switch module 1. When a user presses a key 410, the abutment column 411 under the key 410 moves downward to abut against the exposed top column 202 on the switch mechanism 200 of the switch module 1 (see fig. 2A). As shown in fig. 3, the switch mechanism 200 further includes a base 240 and an actuator 250 pivotally connected to the base 240. The base 240 is disposed on the circuit board 230, the circuit board 230 is provided with the optical switch 232, the tail end of the actuating member 250 is provided with an extended trigger portion 252, and the trigger portion 252 corresponds to the optical switch 232. The triggering part 252 can cut off the optical switch 232 before the actuating member 250 is stressed, and when the top column 202 is stressed and pressed down, the front end of the actuating member 250 is pressed to rotate the actuating member 250 under stress, so that the triggering part 232 leaves the optical switch 232, and the optical switch 232 is conducted to trigger the generation of a signal. The external force required for the rotation of the actuator 250 can be changed by adjusting the magnetic force applied to the first magnetic attraction member 210 at the tail end of the actuator 250.

In practice, at least one operating member (such as a button) may be disposed on the input device 400, where the at least one operating member is disposed corresponding to the magnetic force adjustment unit 300. When the user operates the at least one operation member, the relative positional relationship of the magnetic force adjusting unit 300 with respect to the switch mechanism 200 changes, so that the magnetic attraction force between the two changes to adjust the force required by the switch module 1 when pressing.

Of course, the present invention is capable of other various embodiments and its several details are capable of modification and variation in light of the present invention by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
