All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The rotary key provided by the invention comprises a keycap, a sliding detection device, a key controller, a rotary detection device and a rotary controller.

The keycap is connected with the shell, and can slide along a straight line relative to the shell and also rotate relative to the shell. Specifically, the key cap has the center pin, with the key cap complex be provided with the pipe of ba, pipe of ba and casing fixed connection. The bus pipe is provided with a through hole, the central shaft penetrates through the through hole to slide and rotate along the through hole, and the bottom end of the central shaft is connected with a clamp spring to prevent the central shaft from being separated from the through hole.

The sliding detection device is electrically connected with the sliding controller and used for detecting the sliding of the keycap and sending the sliding detection result to the key controller, and the key controller is used for controlling the output of the first execution component according to the sliding detection result. The linear sliding of the keycap is detected through the sliding detection device, the sliding detection device can be a Dome sheet and the like, the sliding controller can be a hard circuit board or a flexible circuit board and the like, and the Dome sheet is placed in a contact area of the keycap and the hard circuit board to realize the function of a conventional key. The control of the key sliding function may refer to the prior art, and the structure and principle of the corresponding sliding detection device may refer to the prior art, which is not limited herein.

The rotary key provided by the invention is added with a rotary control function on the basis of a common key. The rotation detection device is electrically connected with the rotation controller, the rotation detection device is used for detecting the rotation of the keycap and sending the rotation detection result to the rotation controller, and the rotation controller is used for controlling the output of the second execution component according to the rotation detection result. The first executing component and the second executing component may be the same component of the device, or may be different components of the device. That is to say that the rotation of the key cap can likewise trigger the adjustment of a corresponding function, which can be the same as, preferably different from, the function corresponding to the use of the key cap as a key. The output of the second execution unit may specifically be an increase and decrease in sound volume, or an increase and decrease in noise reduction level, or the like. The output of the first execution component may specifically be to return, or to turn on audio playing, and the like. The specific functions corresponding to the output of the first execution component and the output of the second execution component may be set according to the needs of the device, and are not specifically limited herein.

The specific implementation of the corresponding function when the key cap is rotated can be as follows in different ways. The following description will be given by way of example of different embodiments.

In one embodiment, referring to fig. 1, the rotation detecting device includes an intermediate plate 300, a transmitting plate 100, and a receiving plate 200.

Wherein the middle plate 300 is connected with the key cap to rotate synchronously. When the key cap has a central axis, the middle plate 300 is fixedly connected to the central axis, and when the key cap rotates, the middle plate 300 and the key cap rotate synchronously. Preferably, the middle plate 300 is perpendicular to the rotation axis of the key cap, so that the middle plate 300 is not easily interfered with other components when rotating, and is conveniently matched with the launching pad 100 and the receiving pad 200. The intermediate disc 300 is provided with a plurality of through holes 301, and the number of the through holes 301 is preferably set as many as required to improve the accuracy and sensitivity of the rotation control. The shape, size, etc. of the through hole 301 may be set as required, and is not particularly limited herein.

The launching pad 100 and the receiving pad 200 are respectively disposed at both sides of the middle pad 300, and both of them do not rotate with the key cap, and can be specifically fixedly connected in the housing. Preferably, the launching tray 100 and the receiving tray 200 are parallel to the middle tray 300, respectively, so as to be easily engaged with the launching tray 100 and the receiving tray 200. The transmitting device 101 is arranged on the transmitting disc 100, the receiving device 201 is arranged on the receiving disc 200 and used for receiving signals sent by the transmitting device 101, the receiving device 201 is arranged corresponding to the transmitting device 101, and particularly, under the condition that the receiving device 201 is opposite to the transmitting device 101, namely, the transmitting device 101 is opposite to the through hole 301, the signals sent by the receiving device 201 are received by the through hole. Specifically, the line connecting the receiving device 201 and the transmitting device 101 may be parallel to the rotation axis of the key cap, so as to better receive the signal emitted by the transmitting device 101. The number of the specific transmitting devices 101 and the number of the specific receiving devices 201 are set according to needs, and the two are preferably set in one-to-one correspondence. The greater the number of transmitting devices 101 and the greater the number of receiving devices 201, the higher the corresponding control accuracy.

The emitting device 101 and the receiving device 201 are electrically connected to a rotation controller, and the rotation controller is configured to determine a rotation angle and/or a direction of the keycap according to a change in intensity of a signal received by the receiving device 201 and correspondingly control the second executing component to perform corresponding output. The transmitting device 101 may be specifically an infrared transmitter or a laser transmitter, and the receiving device 201 is correspondingly an infrared receiver or a laser receiver. The rotation controller may specifically control the operation and stop of the launching device 101. A signal, such as an infrared signal or a laser signal, transmitted from the transmitting device 101 is transmitted to the intermediate tray 300, and when the signal is opposite to the through hole 301 of the intermediate tray 300, the signal can be transmitted to the receiving tray 200 through the through hole 301, so that the corresponding receiving device 201 of the receiving tray 200 receives the signal. When the middle disc 300 rotates with the keycap until the signal sent by the transmitter 101 is opposite to the non-through hole area on the middle disc 300, the signal cannot be sent to the receiving disc 200 due to the blocking signal of the middle disc 300, and the corresponding receiver 201 cannot receive the signal sent by the transmitter 101. When the middle disc 300 rotates along with the keycap until the signal part sent by the sending device 101 is opposite to the through hole 301 on the middle disc 300 and is opposite to the non-through hole area, the partial signal can be sent to the receiving disc 200, so that the corresponding receiving device 201 on the receiving disc 200 can receive the partial signal. Therefore, the rotating controller can obtain the rotating state of the keycap through the signal strength change received by the receiving device 201. The signal strength change includes both the order in which maxima, or minima, occur, and signal enhancement or attenuation. Specifically, the rotation state may include a rotation angle, a rotation direction, or both the rotation direction and the rotation angle, according to the difference in the number of the through holes 301, the difference in the number of the transmitting devices 101 and the receiving devices 201, and the like. The rotation controller correspondingly controls the second execution part to output correspondingly according to the determined rotation state of the keycap. Such as controlling the increase or decrease of the volume according to the direction of rotation, and controlling the degree of increase or decrease of the volume according to the angle of rotation, etc.

The rotation controller may be a hard circuit board or a flexible circuit board. The transmitting reel 100 and the receiving reel 200 may each employ a rigid circuit board or a flexible circuit board. Preferably, the hard circuit board or the flexible circuit board is used as the launching tray 100 and the receiving tray 200, and also used as a rotation controller, so that the whole structure is simple and compact, and the control is reliable.

In the case where the intermediate tray 300 is provided with a plurality of through holes 301, the plurality of through holes 301 are uniformly distributed in the circumferential direction around the rotation axis of the key cap. The through holes 301 are uniformly distributed, so that the control precision and the sensitivity can be improved, and meanwhile, the control logic is relatively simple.

Specifically, the distance between two adjacent through holes 301 is equal to the diameter of the through hole 301. So set up, be convenient for control logic's setting. Further, the signal emitted by the emitting device 101 corresponds to the size of the through hole 301. If the size of the laser beam emitted by the emitting device 101 is consistent with the size of the through hole 301, the laser beam circulates in a way that the laser beam is opposite to the through hole 301, part of the laser beam is opposite to the through hole 301, the laser beam is completely staggered with the through hole 301, part of the laser beam is opposite to the through hole 301, and the laser beam is opposite to the through hole 301 along with the rotation of the intermediate disk 300, so that the signal received by the corresponding receiving device 201 is gradually weakened to zero from the strongest point, and then gradually increased to. The rotation controller can determine the rotation angle and direction of the keycap according to the signal change received by the receiving device 201.

On the basis of the above embodiment, the launching disc 100 is provided with a plurality of launching devices 101, and in the case that one launching device 101 is directly opposite to one of the through holes 301, at least another launching device 101 is staggered with each through hole 301, and the receiving devices 201 and the launching devices 101 are arranged in one-to-one correspondence. The control precision is improved by arranging a plurality of transmitting devices 101 to cooperate. The receiving device 201 and the transmitting device 101 are arranged in a one-to-one correspondence manner, and the two devices are arranged in a specific opposite manner. Under the condition that one transmitting device 101 is opposite to one of the through holes 301, at least one other transmitting device 101 is staggered with the through holes 301, in the rotating process of the middle disc 300, the corresponding relations between at least two transmitting devices 101 and the through holes 301 are different, the strength of signals received by the corresponding receiving devices 201 is different, and further the rotating angle and the direction of the keycap can be more accurately determined through the strength change of the signals received by the receiving devices 201. Note that, the emitting device 101 is staggered from each through hole 301, and includes a case where the emitting device 101 is located between two adjacent through holes 301, and a portion of the emitting device 101 is opposite to the through hole 301. Correspondingly, the emitting device 101 is opposite to the through hole 301, which means that the center of the emitting device 101 is opposite to the center of the through hole 301.

Further, in the case where one emitting device 101 is directly opposed to one of the through holes 301, at least another emitting device 101 is directly opposed to between the adjacent two through holes 301. That is, when the intermediate plate 300 is rotated until one of the transmitters 101 faces one of the through holes 301 and the corresponding receiver 201 receives the strongest signal, at least one other transmitter 101 corresponds to the non-through hole area of the intermediate plate 300, so that the corresponding receiver 201 receives the weakest signal.

For convenience of describing a specific control manner of the rotation controller, the following description will take four transmitting devices 101 provided on the transmitting tray 100 and four receiving devices 201 provided on the receiving tray 200 shown in fig. 1 as an example.

A plurality of uniformly distributed through holes 301 are formed in the intermediate disc 300, so that the diameter of each through hole 301 in the intermediate disc 300 is equal to the distance between the edges of two adjacent through holes 301 for facilitating signal detection; a PCB or FPC, on which the transmitting device 101 and the receiving device 201 are respectively placed, is placed in parallel on both sides of the middle plate 300, i.e., the PCB or FPC is used as the transmitting plate 100 and the receiving plate 200, respectively, and is used as a rotation controller;

the launch pad 100 is provided with four launch devices 101, which are respectively identified as a first launch device 11T, a second launch device 12T, a third launch device 13T and a fourth launch device 14T. The corresponding receiving tray 200 is provided with four receiving devices 201, which are respectively referred to as a first receiving device 11R, a second receiving device 12R, a third receiving device 13R and a fourth receiving device 14R. The emitting devices 101 and the receiving devices 201 are parallel to the middle disc 300 in a one-to-one correspondence mode, and the positions of the emitting devices 101 and the receiving devices 201 are partially parallel to the positions of the through holes 301 in the middle disc 300 and partially staggered.

As shown in fig. 2, which is a partially expanded view of the key rotation axis, S1 indicates a channel corresponding to the first transmitter 11T and the first receiver 11R, S2 indicates a channel corresponding to the second transmitter 12T and the second receiver 12R, S3 indicates a channel corresponding to the third transmitter 13T and the third receiver 13R, and S4 indicates a channel corresponding to the fourth transmitter 14T and the fourth receiver 14R. P1, P2, P3, P4, P5 and P6 are schematic diagrams of relative positions of a rotating shaft and a channel formed by each transmitting device 101 and each receiving device 201 when the keycap rotates to different states. Assuming that the corresponding position of the initial rotation axis and the channel is P1, S1 and S2 correspond to the position of the through hole 301 on the middle plate 300, and S3 and S4 correspond to the position of the non-hole, i.e., the non-cross-sectional area, on the middle plate 300, at this time, the signals transmitted by the first transmitting device 11T and the second transmitting device 12T pass through the through hole 301 on the middle plate 300, so that the signals received by the first receiving device 11R and the second receiving device 12R are strongest, and can default to 1, while the signals transmitted by the third transmitting device 13T and the fourth transmitting device 14T pass through the non-hole, i.e., the non-cross-sectional area, on the middle plate 300, so that the signals received by the third receiving device 13R and the fourth receiving device 14R are weakest, and can default.

When the rotating shaft rotates slightly, the position relation of the rotating shaft and the channel is P2, at this time, S1, S2, S3 and S4 intersect with the through hole 301 and the non-hole position on the intermediate disk 300, and at this time, the signals transmitted by the first transmitting device 11T and the second transmitting device 12T pass through the through hole 301 and the non-hole on the intermediate disk 300, so that the signals received by the first receiving device 11R and the second receiving device 12R are gradually reduced; and the signals transmitted by the third transmitting device 13T and the fourth transmitting device 14T pass through the through hole 301 and the non-through hole on the middle plate 300, so that the signals received by the third receiving device 13R and the fourth receiving device 14R are gradually enhanced.

When the rotating shafts continue to rotate in the same direction, the position relationship of the rotating shafts and the channels is P3, at this time, S1 and S2 both correspond to the positions of the non-holes on the intermediate disk 300, and S3 and S4 correspond to the positions of the through holes 301 on the intermediate disk 300, at this time, the signals transmitted by the first transmitting device 11T and the second transmitting device 12T pass through the non-holes on the intermediate disk, so that the signals received by the first receiving device 11R and the second receiving device 12R are the weakest and can default to 0, and the signals transmitted by the third transmitting device 13T and the fourth transmitting device 14T pass through the through holes 301 on the intermediate disk 300, so that the signals received by the third receiving device 13R and the fourth receiving device 14R are the strongest and can default to 1.

When the rotating shafts continue to rotate in the same direction, the position relationship between the rotating shafts and the channels is P4, at this time, the through holes 301 and the non-hole positions on the intermediate disc 300 corresponding to the rotating shafts S1, S2, S3 and S4 are crossed, and at this time, the signals transmitted by the first transmitting device 11T and the second transmitting device 12T pass through the through holes 301 and the non-holes on the intermediate disc 300, so that the signals received by the first receiving device 11R and the second receiving device 12R are gradually enhanced; and the signals transmitted by the third receiving device 13T and the fourth receiving device 14T pass through the through hole 301 and the non-hole on the rotating disk, so that the signals received by the third receiving device 13R and the fourth receiving device 14R are gradually weakened.

When the rotating shafts continue to rotate in the same direction, the position relationship of the rotating shafts and the channels is P5, at this time, S1 and S2 correspond to the positions of the non-holes on the intermediate disk 300, and S3 and S4 correspond to the positions of the through holes 301 on the intermediate disk 300, at this time, the signals transmitted by the first transmitting device 11T and the second transmitting device 12T pass through the non-holes on the intermediate disk 300, so that the signals received by the first receiving device 11R and the second receiving device 12R are the weakest and can default to 0, and the signals transmitted by the third transmitting device 13T and the fourth transmitting device 14T pass through the through holes 301 on the intermediate disk 300, so that the signals received by the third receiving device 13R and the fourth receiving device 14R are the strongest and can default to 1. Summarizing the above description, table 1 below shows that 1 represents the strongest signal, ↘ represents the gradual decrease of the signal, ↗ represents the gradual increase of the signal, and 0 represents the weakest signal; then the rotation direction and speed can be conveniently judged by detecting the sequence of 1 or 0 through S1, S2, S3 and S4, or whether the signal is enhanced or weakened, thereby realizing the rotation function of the rotary key.
