Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the key according to the embodiment of the present invention includes: a key cap 11, a connecting unit 12, an infrared light emitting unit 13, a base 14, an infrared receiving unit 15 and a signal processing unit (not shown in the figure). Wherein the keycap 11 is connected with the base 14 through the connecting unit 12; the infrared light-emitting unit 13 and the infrared receiving unit 15 are arranged in a space formed by the keycap 11 and the base 14; the infrared receiving unit 15 is connected to the signal processing unit, and the signal processing unit is disposed on the base 14.
Since the key cap has a bottom end and a side wall, a certain space can be formed between the key cap 11 and the base 14 in the process of forming the key. For example, the infrared light emitting unit or the infrared receiving unit may be disposed at any position in the space, as long as the relative position of the two is set such that the infrared signal emitted by the infrared light emitting unit can be received by the infrared receiving unit, for example, the side wall of the keycap, the bottom end of the keycap, or the portion of the base corresponding to the bottom end, or any position in the space.
According to the key of this embodiment, when the key is pressed, the infrared signal emitted by the infrared light emitting unit is received by the infrared receiving unit; the infrared receiving unit generates a signal output value according to the intensity of the infrared signal and sends the signal output value to the signal processing unit; and the signal processing unit determines the stroke of the key according to the signal output value.
In a specific application, the infrared light emitting unit may comprise the following different compositions:
the first composition is as follows: as shown in fig. 2, the infrared light emitting unit 13 includes an infrared emitter 131 and a light reflecting module 132. Wherein the infrared emitter 131 is disposed on the base 14, and the reflective module 132 is disposed on the inner shell of the keycap. The infrared emitter 131 emits an infrared signal, and the infrared signal is reflected to the infrared receiving unit 15 by the reflective module 132. Fig. 2 shows a state where the infrared receiving unit 15 is provided on a base. In fact, the infrared receiving unit may not be limited to be disposed on the base, but may be disposed at any position in the space formed by the key cap 11 and the base 14 as long as it can receive the infrared signal of the infrared emitter reflected by the reflective film.
Wherein the light reflecting module may use a light reflecting film in a specific application. The reflective film can be attached to any position of the inner shell of the keycap, the size of the area of the reflective film is not limited, and the reflective film can reflect infrared signals emitted by the infrared emitter at the position or in the area. Since the infrared emitter is disposed on the base, in order to more fully reflect the infrared signal emitted by the infrared emitter, as shown in fig. 2, the reflective film 132 may be disposed at an end of the inner shell of the key cap opposite to the base, that is, at the bottom end of the key cap, and the area of the reflective film is matched with the area of the bottom end of the key cap.
The second composition is as follows: as shown in FIG. 3, the IR light unit 13 includes an IR emitter 132, the IR emitter 132 being disposed on the inner shell of the keycap. Since the infrared receiving unit 15 is disposed in the space formed by the keycap and the base, the position of the infrared emitter on the inner shell of the keycap is set as long as the infrared signal emitted by the infrared emitter can be directly received by the infrared receiving unit. In order to obtain more accurate key stroke, as shown in fig. 3, the infrared receiving unit 15 is disposed on a base, and the infrared emitter 132 may be disposed on an end of the inner shell of the key cap opposite to the base, i.e., a bottom end of the key cap. Therefore, the infrared receiving unit is arranged on the base, and the infrared emitter is opposite to the infrared receiving unit, so that the infrared signal emitted by the infrared emitter can be better received by the infrared receiving unit.
The third composition is as follows: unlike the case shown in fig. 2, in this composition, the infrared light emitting unit includes only the infrared emitter 131 without the reflective film of fig. 2, while the infrared emitter 131 is disposed on the base. At this time, the infrared emitter emits an infrared signal, and the infrared signal is reflected to the infrared receiving unit through the inner shell of the keycap. Fig. 2 shows a state where the infrared receiving unit 15 is provided on a base. In fact, the infrared receiving unit may not be limited to be disposed on the base, but may be disposed at any position within the space formed by the keycap 11 and the base 14 as long as it can receive the infrared signal of the infrared emitter reflected by the inner housing.
A fourth composition: as shown in fig. 4, the infrared light emitting unit 13 includes an infrared emitter 133, the infrared emitter 133 is disposed in a space formed by the key cap and the base, and the infrared receiving unit 15 is disposed on an inner housing of the key cap. And the infrared signal emitted by the infrared emitter is directly transmitted to the infrared receiving unit. In order to obtain more accurate key stroke, as shown in fig. 4, the infrared emitter 133 is disposed on the base, and the infrared receiving unit 15 may be disposed on an end of the inner casing of the key cap opposite to the base, i.e., a bottom end of the key cap. Therefore, the infrared emitter is arranged on the base and is opposite to the infrared receiving unit, so that the infrared signal emitted by the infrared emitter can be better received by the infrared receiving unit.
The fifth composition is as follows: as shown in fig. 5, the infrared light emitting unit 13 includes an infrared emitter 137 and a reflective module 138, the infrared emitter 137 is disposed on the inner shell of the keycap, the reflective module 138 is disposed on the base, and an infrared signal emitted by the infrared emitter is reflected to the infrared receiving unit through the reflective module. In order to obtain more accurate key stroke, as shown in fig. 5, the infrared emitter 137 and the infrared receiving unit 15 may be disposed at an end of the inner shell of the key cap opposite to the base, i.e., a bottom end of the key cap, and the reflective film 138 is disposed at an end of the base opposite to the shell inside the key cap. Thus, the infrared signal emitted by the infrared emitter can be better received by the infrared receiving unit.
In order to accurately obtain the key stroke, the signal processing unit may include: a microprocessor and a memory. And after receiving the signal output value, the microprocessor determines the stroke of the key according to the program stored in the memory. Of course, for further cost saving, the signal processing unit may also comprise only a microprocessor, which is itself provided with a storage unit for storing the program. At this time, after receiving the signal output value, the microprocessor determines the stroke of the key according to a program stored in a storage unit of the microprocessor.
Specifically, in the case of the infrared light emitting unit composed of the first, third, and fifth types, when a user presses a key, the distance between the reflective film or the inner casing of the key cap (e.g., the bottom end of the key cap) and the infrared receiver is shortened, the intensity of the infrared signal received by the infrared receiver is increased, and thus the signal output value output by the infrared receiver also changes accordingly. Therefore, the infrared receiver converts the sensed infrared signal into a signal output value of a digital signal and transmits the signal output value to the microprocessor. The microprocessor converts the signal output value into a corresponding key stroke, namely a pressed degree value of the key through correction according to different signal output values.
In the case of the infrared light emitting unit of the second and fourth compositions, when a user presses a key, the distance between the infrared transmitter and the infrared receiver is shortened, the intensity of the infrared signal received by the infrared receiver is increased, and thus the signal output value output by the infrared receiver also emits a corresponding change. Therefore, the infrared receiver converts the sensed infrared signal into a signal output value of a digital signal and transmits the signal output value to the microprocessor. The microprocessor converts the signal output value into a corresponding key stroke, namely a pressed degree value of the key through correction according to different signal output values.
In a specific application, the infrared receiving unit may be an infrared receiver. The base may be a Printed Circuit Board (PCB) board. The connecting unit can be any elastic member, such as a spring, a silica gel pad, and the like. Wherein, the connecting unit can be arranged at the lower part of the keycap, that is, at the edge of the casing of the keycap close to the base (as shown in fig. 1, 2 and 3), of course, the connecting unit can also be arranged at the inner side of the keycap (as shown in fig. 6). The drawings shown in the embodiment are all illustrated by taking the connecting unit arranged at the edge of the shell of the keycap close to the base as an example.
In addition, in order to make the determined key stroke more accurate, both the infrared light emitting unit and the signal processing unit may be disposed on a portion of the base forming a space with the key cap.
Therefore, the key provided by the embodiment of the invention is composed of the optical device, has a simple structure, and is easy to assemble, low in cost and high in sensitivity compared with the prior art.
The terminal device of the embodiment of the invention can also comprise any key. The terminal device may include a mobile terminal, such as a mobile phone. Because the key-press included in the invention is composed of optical devices, the structure is simple, therefore, compared with the prior art, the terminal equipment is simple and convenient to produce and low in cost.
As shown in fig. 7, the method for determining the key stroke according to the embodiment of the present invention includes:
and step 41, when the key is pressed, the infrared receiving unit of the key receives the infrared signal emitted by the infrared light-emitting unit of the key.
And 42, generating a signal output value by the infrared receiving unit according to the intensity of the infrared signal, and sending the signal output value to a signal processing unit of the key, so that the signal processing unit determines the stroke of the key according to the signal output value.
As described above, the infrared light emitting unit includes an infrared emitter and a light reflecting module, or the infrared light emitting unit includes an infrared emitter. Therefore, the steps are specifically as follows:
when infrared luminescence unit includes infrared transmitter and reflection of light module, the infrared signal that the infrared luminescence unit of infrared receiving element receipt button of button launched includes:
infrared signals emitted by the infrared emitter are reflected to the infrared receiving unit through the light reflecting module, and the infrared receiving unit receives the infrared signals;
when the infrared light emitting unit includes the infrared transmitter, the infrared signal that the infrared receiving unit of button received the infrared light emitting unit transmission of button includes:
the infrared receiving unit receives infrared signals transmitted by the infrared transmitter, or the infrared signals are reflected to the infrared receiving unit through the inner shell of the keycap and received.
In the process that the signal processing unit determines the stroke of the key according to the signal output value, different modes can be provided according to the composition of different infrared light-emitting units.
In the case of the infrared light emitting unit composed of the first, third, and fifth configurations, when a user presses a key, a distance between the reflective film or an inner casing of the key cap (e.g., a bottom end of the key cap) and the infrared receiver is shortened, an intensity of an infrared signal received by the infrared receiver is increased, and thus a signal output value output by the infrared receiver also changes accordingly. Therefore, the infrared receiver converts the sensed infrared signal into a signal output value of a digital signal and transmits the signal output value to the microprocessor. The microprocessor converts the signal output value into a corresponding key stroke, namely a pressed degree value of the key through correction according to different signal output values.
In the case of the infrared light emitting unit of the second and fourth compositions, when a user presses a key, the distance between the infrared transmitter and the infrared receiver is shortened, the intensity of the infrared signal received by the infrared receiver is increased, and thus the signal output value output by the infrared receiver also emits a corresponding change. Therefore, the infrared receiver converts the sensed infrared signal into a signal output value of a digital signal and transmits the signal output value to the microprocessor. The microprocessor converts the signal output value into a corresponding key stroke, namely a pressed degree value of the key through correction according to different signal output values.
From the above, it can be seen that, since the key of the embodiment of the present invention is composed of the optical device, the structure is simple, and therefore, compared with the prior art, determining the stroke of the key is easy to implement. Therefore, the method is more convenient to determine the stroke of the key.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
