Description

Multi-key same-program passive transmitter

Technical Field

The utility model relates to a signalling field especially relates to a passive transmitter of multikey with form to make each when laying a plurality of buttons the button can have same stroke, and can touch arbitrary generate electricity and provide the electric energy for the transmission with the corresponding signal of this button touched with pressing the button ground.

Background

In recent years, the development of technology is increasingly reflected in the pursuit of environmental protection, and the development is as large as the popularization of electric vehicles, and as small as signal transmitting devices in the field of signal transmission without battery power supply. Like the passive switch which is popular at present, the passive switch is provided with electric energy output by converting mechanical energy into electric energy, so that the passive switch can send control signals in a wired or wireless mode and is widely applied to doorbell switches and lamp switches. However, in the remote control widely used in the field of signal transmission, even though the power saving technology of the current remote control has achieved a battery replacement cycle acceptable to the user under the condition of using only one button battery for power supply, the current remote control still has difficulty in getting rid of the dependence on the battery, mainly because the current generator for converting mechanical energy into electric energy is difficult to match with the remote control with a plurality of keys.

Specifically, as shown in fig. 1A and 1B of the drawings, a present self-generating remote controller 10P is mainly illustrated, wherein the self-generating remote controller 10P includes a generator 11P, a housing 12P, a driving plate 13P and a plurality of keys 14P disposed on the driving plate 13P, wherein the generator 11P is disposed in the housing 12P, wherein the generator 11P includes a driving rod 111P for driving the driving rod 111P to generate electric energy from the generator 11P, and the driving plate 13P is coupled to the driving rod 111P, so as to be able to drive the keys 14P by applying force. It is understood that the structural configuration of driving the generator 11P by the driving rod 111P makes the effective mechanical energy bearing surface of the generator 11P small, that is, the effective force application surface is concentrated on the driving rod 111P when the generator 11P is applied with force for generating electricity. Further, the self-generating remote controller 10P is provided with a plurality of the buttons 14P, that is, the buttons 14P of the self-generating remote controller 10P are not concentrated, unlike the generator 11P in which effective force application surfaces are concentrated, so that it is difficult to uniformly apply force to the driving lever 111P when applying force to different buttons 14P of the self-generating remote controller 10P. Therefore, when any one of the keys 14P is forced to drive the self-generating remote controller 10P, the driving board 13P may incline to different degrees, that is, the strokes of the keys 14P are different, so that the self-generating remote controller 10P is difficult to obtain a good control hand feeling.

In order to maintain the same stroke of each key of the remote controller and provide electric energy output for the remote controller through the generator, the invention with the publication number of CN107852080A discloses another embodiment of the self-generating remote controller, in which the force application driving of the generator of the self-generating remote controller and the pressing of the key are operated separately, i.e. the user presses any key on the front side of the self-generating remote controller where the key is arranged and presses the back side of the self-generating remote controller to drive the generator. That is to say, the user holds the self-generating remote controller, and when the key on the front side of the self-generating remote controller is pressed by a thumb in the operation mode of the traditional remote controller, two sections of pressing are needed to form the movement of the back side of the self-generating remote controller relative to the front side of the self-generating remote controller, so that the generator is driven. Therefore, although the keys of the self-generating remote controller can be maintained in the same stroke by adopting the arrangement mode of the keys of the traditional remote controller, the operation mode of the self-generating remote controller is different from that of the traditional remote controller, and good control hand feeling is difficult to obtain.

In summary, even though the current power saving technology of the remote controller has achieved a battery replacement cycle acceptable to the user under the condition of using only one button battery for power supply, the battery requirement of the widely used remote controller is still huge and is not friendly to the environment. The power generator with relatively concentrated effective force application surface is difficult to match with the remote controller with a plurality of keys, and the current self-generating remote controller is difficult to conform to the operation mode of the traditional remote controller while maintaining the same stroke of each key, so the power generator is difficult to popularize to reduce the use of batteries.

Referring to fig. 2A and 2B of the drawings of the present disclosure, a multi-key same-stroke passive transmitter 100 according to an embodiment of the present disclosure is illustrated, which mainly shows a structural schematic diagram of the multi-key same-stroke passive transmitter 100 in different states. The multi-key stroke-identical passive transmitter 100 comprises a plurality of keys 110, a balance seat 120, a key distribution plate 130, a power generation unit 140 and a signal transmission unit 150, wherein the balance seat 120 comprises two pivoting members 121, each pivoting member 121 has a pivoting portion 1211, a linkage portion 1212 and a balance end 1213, wherein the two pivoting members 121 are respectively pivotally disposed at the pivoting portions 1211 and coupled to the linkage portion 1212, such that when any pivoting member 121 is pivoted, the other pivoting member 121 is pivotally linked, wherein a connecting line of the two pivoting portions 1211 of the two pivoting members 121 is parallel to a connecting line of the two balance ends 1213, such that a balance plane 122 is formed at a plane where the two balance ends 1213 are located, such that when any pivoting member 121 is pivoted, the balance plane 122 can be maintained to move in parallel, wherein each key 110 is disposed on the key distribution plate 130, the key arrangement board 130 is maintained at the two balance ends 1213 on the balance surface 122, so as to maintain the parallel movement of the key arrangement board 130 when any one of the keys 110 is pressed, and further maintain the keys 110 in the same stroke, wherein the power generation unit 140 is coupled to the balance base 120 so as to be driven by the balance base 120 to generate electric energy, wherein the signal transmission unit 150 is electrically connected to the power generation unit 140, and when at least one of the keys 110 is pressed to drive the power generation unit 140, the signal transmission unit 150 transmits at least one control signal matched with the pressed key 110 under the power supply of the power generation unit 140.

Specifically, in this embodiment of the present invention, the balance base 120 further includes a balance member 123, wherein the two pivot members 121 are pivotally disposed on the balance member 123 respectively at the linking portion 1212, so as to form a structural relationship that the two pivot members 121 are coupled to the linking portion 1212 through the balance member 123.

In particular, the two pivoting members 121 are disposed in parallel with each other, and the linkage portion 1212 is integrally formed at the balance end 1213, so that the balance surface 122 is formed on the plane where the balance member 123 is located, wherein the key distribution plate 130 is disposed on the balance member 123 to form a positional relationship where the key distribution plate 130 is maintained at the balance end 1213 on the balance surface 122, and further, when any one of the keys 110 is pressed, the key distribution plate 130 can be maintained in parallel movement by the balance member 123.

Further, the multi-key and one-stroke passive transmitter 100 further includes a housing 160, wherein the pivot portions 1211 of the two pivot members 121 are respectively pivotally disposed on the housing 160, so as to form a structural relationship that the two pivot members 121 are respectively pivotally disposed on the pivot portions 1211 thereof.

It is understood that the two pivoting members 121 are disposed parallel to each other, i.e., the connecting line of the pivot portion 1211 and the balance end 1213 of each pivoting member 121 is parallel to each other, rather than limiting the shape of the pivoting member 121, for example, the two pivoting members 121 may be disposed to extend from the pivot portion 1211 to the balance end 1213 in a bending manner, as long as the connecting line of the pivot portion 1211 and the balance end 1213 of each pivoting member 121 is parallel to each other, i.e., the two pivoting members 121 are disposed in a parallel relationship with each other.

It can be further understood that the linkage portion 1212 of each pivoting member 121 is integrally formed at the balance end 1213, and a connecting line of the two pivot portions 1211 of the two pivoting members 121 is parallel to a connecting line of the two balance ends 1213, that is, a connecting line of the pivot portion 1211 of each pivoting member 121 and the balance end 1213, a connecting line of the two balance ends 1213 of the two pivoting members 121, and a connecting line of the two pivot portions 1211 of each pivoting member 121 form a parallelogram, so that when any one of the pivoting members 121 is pivoted, the balance surface 122 can be maintained to move in parallel, and thus the keys 110 can be maintained to move in the same stroke.

Further, in this embodiment of the present invention, the power generating unit 140 includes a driving arm 141, wherein the power generating unit 140 is configured to generate power when the driving arm 141 is driven, and wherein the driving arm 141 is coupled to the balance member 123, so that the balance member 123 can move in parallel to drive the driving arm 141 when any one of the buttons 110 is pressed.

It should be noted that the balance member 123 can be maintained to move in parallel when any one of the keys 110 is pressed, and when different keys 110 are pressed, the balance member 123 can be maintained to move in parallel uniformly, that is, each key 110 is maintained to have the same stroke, so that when different keys 110 are pressed, uniform driving of the driving arm 141 can be formed, so that the power generation amount of the power generation unit 140 can be maintained to be stable, and further, the multi-key same-stroke passive transmitter 100 has better stability.

Further, the multi-key same-stroke passive transmitter 100 further includes a reset unit 170, wherein the reset unit 170 is configured to restore the key distribution plate 130 and the driving arm 141 to a state before the key 110 is pressed after releasing the pressing of the key 110, and further restore the key 110 arranged on the key distribution plate 130 to a state before the key 110 is pressed.

Specifically, in this embodiment of the present invention, the reset unit 170 is disposed between the driving arm 141 and the housing 160, so that when the button 110 is pressed, the reset unit 170 can be driven by the driving arm 141 to store potential energy, and after the button 110 is released from being pressed, the reset unit 170 can restore the button plate 130 and the driving arm 141 to a state before the button 110 is pressed, and thus restore the button 110 disposed on the button plate 130 to a state before the button 110 is pressed, by releasing the stored potential energy.

It should be noted that, in this embodiment of the present invention, the reset unit 170 is configured as a spring 171 and is disposed between the driving arm 141 and the housing 160, wherein since the driving arm 141 is coupled to the balance member 123 of the balance base 120, in some embodiments of the present invention, the reset unit 170 may also be disposed between the housing 160 and the balance base 120, which is not limited by the present invention.

In addition, it can be understood that the reset unit 170 may also be configured as an element with elastic characteristics, such as a torsion spring, a spring plate, and a rubber band, or as a magnetic element capable of attracting or repelling each other, which is not limited by the present invention.

It should be noted that, the arrangement of the balance seat 120 of the present invention enables the keys 110 arranged on the key arrangement board 130 to be maintained in the same stroke, that is, when pressing different keys 110, on the premise that the strokes of the keys 110 themselves are consistent, since the key arrangement board 130 can be maintained in parallel movement without tilting, the pressing strokes of the keys 110 can be maintained consistently, so that the operation of the multi-key same-stroke passive transmitter 100 can have good hand feeling.

In particular, the power generating unit 140 can be driven by a pressing operation of any one of the keys 110 to conform the operation of the multi-key active transmitter 100 to the operation of a conventional remote controller without additional pressing operations, wherein in order to further conform the operation of the multi-key active transmitter 100 to the operation of a conventional remote controller, in this embodiment of the present invention, the keys 110 are elastically maintained between the housing 160 and the key distribution plate 130, such as the portions of the keys 110 between the housing 160 and the key distribution plate 130 can be compressively disposed, so that when any one of the keys 110 is pressed, even if the key distribution plate 130 moves in parallel in the direction in which the key 110 is pressed, the compressed portions of the other non-pressed keys 110 between the housing 160 and the key distribution plate 130 can be expanded, further, the button 110 which is not pressed is kept protruding from the housing 160, so that the operation of the multi-button co-program passive transmitter 100 can completely conform to the operation mode of the conventional remote controller, and therefore, the multi-button co-program passive transmitter is suitable for replacing the conventional remote controller to reduce the use of batteries, thereby being beneficial to environmental protection and energy saving.

Specifically, the portion of the key 110 between the housing 160 and the key distribution plate 130 may be disposed in a compressed manner, that is, the portion of the key 110 between the housing 160 and the key distribution plate 130 may be disposed in a resilient material or structure, for example, a barrel-shaped structure made of a rubber material, and disposed in a compressed manner when the key 110 is not pressed, or a compressed spring is disposed between each of the key 110 and the key distribution plate 130. Thus, when any one of the keys 110 is pressed, the key arrangement plate 130 moves in parallel in the direction in which the key 110 is pressed, and at the same time, other non-pressed keys 110 are extended between the housing 160 and the key arrangement plate 130, so that the non-pressed keys 110 are maintained to protrude from the housing 160.

In particular, in this embodiment of the present invention, the key board 130 is configured as a circuit board integrated with a circuit, wherein the keys 110 are configured as conductive silicone keys or keys that are pressed to be able to drive a micro switch disposed on the circuit board in a force conduction manner, which is not limited by the present invention. In some embodiments of the present invention, the circuit portion of the multi-key same-stroke passive transmitter 100 is disposed on a circuit board fixedly disposed, such as a circuit board fixedly disposed on the housing 160, wherein the key 110 is disposed on the key distribution board 130, so that the key 110 is linked with the key distribution board 130, and when any one of the keys 110 is pressed, the key distribution board 130 can be linked to drive the balance seat 120, so as to drive the power generation unit 140 through the balance seat 120, and switch on the control signal circuit corresponding to the key 110 on the circuit board through the pressed key 110, which is not limited by the present invention.

That is, the key distribution plate 130 is disposed on the balance surface 122 to be capable of linking the keys 110 with the balance base 120, so that when any one of the keys 110 is pressed, the balance base 120 is driven by the key distribution plate 130 in a linked manner, wherein the key distribution plate 130 can be disposed as a circuit board integrated with a circuit, wherein the keys 110 can be disposed as conductive silicone keys or keys that drive corresponding switches (such as micro switches and conductive silicone key switches) through force conduction, which is not limited by the present invention.

It should be noted that, in this embodiment of the present invention, the balance base 120 and the power generating unit 140 further form a balance driving power generating device 200, so as to drive the power generating unit 140 at any position of the balance surface 122, and make the driving of the balance base 120 at any position of the balance surface 122 have the same stroke, that is, the balance driving power generating device 200 can be driven in a balanced manner at any position of the balance surface 122 to generate electric energy.

It can be understood that the balance-driven power generation device 200 has a balanced operation experience and a larger driving area relative to the power generation unit 140, so that the balance-driven power generation device 200 can be applied to a remote controller, a multi-key and single-key switch, and other passive control devices in the field of passive control as a separate product or module to provide power output through balanced driving in a larger area range.

Referring to fig. 3A and 3B of the drawings of the present disclosure, a multi-key same-stroke passive transmitter 100A according to another embodiment of the present disclosure is illustrated, which mainly shows a structural schematic diagram of the multi-key same-stroke passive transmitter 100A in different states.
