Referring to fig. 1, fig. 1 is an external perspective view of a reflective optical axis key 10 according to the present invention. To achieve at least one of the above advantages or other advantages, an embodiment of the present invention provides a reflective optical axis key 10 for generating a signal, wherein the upper portion of the reflective optical axis key 10 is a key cap 14, and the lower portion is a key seat 12.

Referring to fig. 2 in conjunction with fig. 1, fig. 2 is an exploded view of a reflective optical axis key 10 according to the present invention. As best seen in the figures, the reflective optical axis key 10 includes a key cap 14, a key pad 12, a transceiver module 16, and a reflective element 18.

The key cap 14 is coupled to the key pad 12 and can slide with a certain range of travel relative to the key pad 12. The key cap 14 further includes a key post 1402, the bottom of the key base 12 may be protruded with a positioning guide post 24 corresponding to the key post 1402, and the positioning guide post 24 is opened with a key base hole 1202, and in addition, the positioning guide post 24 may be opened with a light-transmitting slot (not shown) to prevent the positioning guide post 24 from blocking the signal light.

The key cylinder 1402 can pass through the key seat hole 1202, and the key cap 14 can be reciprocally displaced with the key cylinder 1402 with a certain stroke relative to the key seat 12.

Further, the key caps 14 and the key bases 12 are detachably mounted to facilitate assembly, replacement and maintenance of the reflective optical axis keys 10.

The transceiver module 16 is fixed to the key pad 12 for transmitting signal light and receiving signal light. The signal light may be infrared light, but the present invention is not limited thereto. The transceiver module 16 is shown as a unitary structure, and the transceiver module 16 further includes a transmitting unit 1602 and a receiving unit 1604, where the transmitting unit 1602 emits signal light, and the signal light is reflected to the receiving unit 1604 through the reflecting element 18.

Further, the transceiver module 16 may be a separate structure. The separate transceiver module 16 includes a transmitting unit 1602, a receiving unit 1604, and a light blocking element (not shown) that are independent of each other, the transmitting unit 1602 and the receiving unit 1604 are respectively disposed on the key pad 12 and correspond to the reflecting element 18, and are separated from each other by the light blocking element, and the working principle of the separate transceiver module 16 is the same as that of the integrated transceiver module 16, and is not described again.

A reflective element 18 is secured to the key cap 14 for reflecting signal light emitted by the transceiver module 16 and enabling the signal light to be reflected to the transceiver module 16, wherein one of signal input and disconnection can be made when the reflective element 18 is in the optical path of the signal light.

Further, the reflecting element 18 may be an arc-shaped reflecting mirror surface, which reflects more signal light to the receiving unit 1604 to have excellent light reflecting performance.

Further, the key cap 14 may be formed with a slot (not shown), the reflective element 18 is clamped in the slot, the key seat 12 may be formed with a groove (not shown), the transceiver module 16 is accommodated in the groove and corresponds to the reflective element 18, and the transceiver module 16 is electrically connected to the circuit board via the groove.

In addition, the reflective optical axis key 10 may further include a reset component 22, a portion of the reset component 22 abuts against the key cap 14, and another portion of the reset component 22 abuts against the key seat 12, so that the key cap 14 can slide away from the reset position relative to the key seat 12. The return assembly 22 may be a resilient member such as a spring or a leaf spring.

In the illustrated example, the spring is sleeved on the key post 1402, and when the key cap 14 is pressed down (i.e. in a pressed state), the spring has an elastic restoring force, and when the pressing external force is released (i.e. in a normal state), the elastic restoring force enables the key cap 14 to slide away from the reset position relative to the key base 12.

In the case of a spring, one end of the spring abuts against the key post 1402, and the other end of the spring is fixed to the key pad 12, and when the key cap 14 is pressed down (i.e. in a pressed state), the spring has an elastic restoring force, and when the pressing external force is released (i.e. in a normal state), the elastic restoring force enables the key cap 14 to slide away from the key pad 12.

Therefore, when the reflective optical axis key 10 is in a normal state, the key cap 14 is far away from the key base 12, and therefore the reflective element 18 is not in the optical path of the signal light generated by the emitting unit 1602, so that the reflective element 18 cannot reflect the signal light, and the receiving unit 1604 cannot receive the signal light, and therefore the reflective optical axis key 10 cannot generate a signal. When the reflective optical axis key 10 is in the pressed state, the key cap 14 is close to the key seat 12, and the reflective element 18 is located in the optical path of the signal light generated by the emitting unit 1602, so that the reflective element 18 reflects the signal light to the receiving unit 1604, which can form one of signal input and disconnection.

Please refer to fig. 2 with reference to fig. 3, fig. 4 and fig. 5, in which fig. 3 is a top view of the reflective optical axis key 10 of the present invention, fig. 4 is a bottom view of the reflective optical axis key 10 of the present invention, and fig. 5 is a left side view of the reflective optical axis key 10 of the present invention. As best seen in fig. 4, the reflective element 18 may include a main reflective plate 1802 and at least one auxiliary reflective plate 1804, and two auxiliary reflective plates 1804 are illustrated, so that the auxiliary reflective plates 1804 capture and reflect the originally divergent signal light, thereby expanding the reflective range and enhancing the reflective strength.

To achieve at least one of the advantages described above or other advantages, another embodiment of the present invention provides a reflective optical axis key 10, the reflective optical axis key 10 including a key base 12, a key cap 14, a transceiver module 16, and a reflective element 18. The transceiver module 16 is disposed on the bottom surface of the key pad 12, and the reflective element 18 is fixedly disposed on the side surface of the key cylinder 1402.

When the reflective optical axis key 10 is in the normal state shown in fig. 6, the reflective element 18 is not in the optical path of the signal light, and cannot reflect the signal light, and the reflective optical axis key 10 cannot generate an input or output signal; when the reflective optical axis key 10 is in the pressed state of fig. 7, the reflective element 18 is located in the optical path of the signal light, and reflects the signal light to the receiving unit 1604, which can form the input state of the signal. Of course, the reflection element 18 may be disposed on the optical path of the signal light in a normal state, and the reflection element 18 may be separated from the optical path of the signal light in a pressed state, so that the signal light may be turned off instead of being input.

When the reflective optical axis key 10 is in the normal state shown in fig. 8, the reflective element 18 is not in the optical path of the signal light, and cannot reflect the signal light, and the reflective optical axis key 10 cannot generate an input or output signal; when the reflective optical axis key 10 is in the pressed state of fig. 9, the reflective element 18 is located in the optical path of the signal light, and reflects the signal light to the receiving unit 1604, which can form the input state of the signal.

Of course, the reflection element 18 may be disposed on the optical path of the signal light in a normal state, and the reflection element 18 may be separated from the optical path of the signal light in a pressed state, so that the signal light may be turned off instead of being input.

In addition, the reflective element 18 may be disposed on other components of the key cap 14 instead of the key post 1402. For example, the key cap 14 may be provided with a pillar structure (not shown) protruding therefrom, the reflective element 18 may be disposed below the pillar structure, the key pad 12 may be provided with an opening, and the transceiver module 16 may be disposed on the bottom surface of the key pad 12.

When the reflective optical axis key 10 is in a normal state, the reflective element 18 is not in the optical path of the signal light, and cannot reflect the signal light, and the reflective optical axis key 10 cannot generate an input or output signal; when the reflective optical axis key 10 is in the pressed state, the reflective element 18 passes through the opening and is located in the optical path of the signal light, and reflects the signal light to the receiving unit 1604, so as to form the input state of the signal. Of course, the reflection element 18 may be disposed on the optical path of the signal light in a normal state, and the reflection element 18 may be separated from the optical path of the signal light in a pressed state, so that the signal light may be turned off instead of being input.

The key cylinder 1402 can pass through the key seat hole 1202, and the key cap 14 can be reciprocally displaced with the key cylinder 1402 with a certain stroke relative to the key seat 12.

Further, the key caps 14 and the key bases 12 are detachably mounted to facilitate assembly, replacement and maintenance of the reflective optical axis keys 10.

The transceiver module 16 is fixed to the key pad 12 for transmitting signal light and receiving signal light.
