Wherein the operation on each key can drive the micro power generation device in a linkage manner, and each instruction switch is in a first state before the key corresponding to the instruction switch is operated and is maintained in the first state when the key corresponding to the instruction switch is operated; in this way, the stroke and linkage of the instruction switch corresponding to the key do not need to be considered in the design of the linkage structure between the key and the miniature power generation device. Correspondingly, the stress change when the key is operated is directly associated with the driving force of the micro power generation device, so that the operation hand feeling without touch conversion can be obtained.

Description

Technical Field

[0001] The utility model relates to the field of passive switches, in particular to a passive multi-key switch with no-touch conversion. Background Art

[0002] With the development and popularization of low-power wireless communication technology, the current wireless switches, under the basic concept of sustainable development and the unremitting pursuit of convenience and environmental protection, are increasingly inclined to use micro-generators based on the principle of electromagnetic induction to replace batteries for power supply, so as to achieve self-supply of electricity. We know that batteries are consumables and need to be replaced frequently, which will bring some expenses and inconvenience to users; according to statistics, the number of batteries consumed in electronic products in the field of household appliances worldwide is as high as tens of billions each year, which is a huge expense, and a large number of discarded batteries will cause damage to the environment. Therefore, the use of micro-generators to replace batteries in wireless switches has great economic value and environmental significance, and will surely be further popularized as people pursue convenient and environmentally friendly life.

[0003] Specifically, when using a micro-generator to provide power for a wireless switch, the micro-generator is driven to generate power based on the operation of the buttons of the wireless switch, and limited by the volume of the micro-generator based on the principle of electromagnetic induction, the current wireless switch can only use one micro-generator to provide power for the entire wireless switch when configuring the micro-generator. In other words, when the wireless switch is designed with multiple buttons, such as when the wireless switch is a remote control with multiple buttons, the operation of each button needs to be able to achieve the linkage drive of the same micro-generator. In this way, on the one hand, due to the different distribution positions of each button relative to the micro-generator, it is easy to cause differences in the operating stroke and strength of each button, making it difficult to obtain a comfortable operating feel. On the other hand, since the remote control commands corresponding to the buttons are different, before the micro-generator is driven to generate electricity based on the operation of the corresponding button, the operation of the button also needs to be able to drive the command switch corresponding to the button to turn on, so as to turn on the corresponding command circuit before the micro-generator generates electricity. The command switch is usually set as a micro switch device such as a micro switch, a contact switch, and a conductive silicone key switch, and has a certain stroke. Therefore, the button stroke a of the corresponding wireless switch, the stroke b of the command switch corresponding to the button, and the stroke c of the micro-generator are usually the same as Figure 1A The two stroke relationships shown correspond to each other, so that when the current wireless switch is designed with multiple buttons, there is an obvious tactile conversion in the operation of each button and it is difficult to obtain a comfortable operating feel. Figure 1B Corresponds to Figure 1A One of the trip relationships shown further reveals this flaw, such as Figure 1BAs shown, when operating the multi-button self-generating switch of the prior art, the button needs to be pressed by the stroke of the command switch b plus the stroke of the micro-generator c; that is, in one pressing operation, the user will clearly perceive two stepped setback vibrations with different strengths from the command switch b and the micro-generator c, or two different operating strokes cause the product to make two sounds, thereby generating double-ring noise, resulting in a poor experience and a long operating stroke. Especially in the design of remote control products, this defect is unacceptable to users. At the same time, since the micro-generator only generates electricity for about 0.001 seconds, the operation of each button needs to drive the command switch corresponding to the button to turn on before driving the micro-generator to generate electricity, otherwise the power generation will not be enough to turn on the command switch, so that the linkage structure between each button and the corresponding command switch and the micro-generator is complex, with high precision requirements, and requires a large button stroke design to ensure the reliability of the linkage structure between each button and the corresponding command switch and the micro-generator.

[0004] Generally speaking, multi-button battery remote controls are widely used in life. For example, TV remote controls usually have a key travel of only 0.2-0.5 mm. During operation, each button only needs to perform the single function of generating command information. Although there are many buttons, there is no need to consider the pressing travel and pressing force, let alone the accuracy of each button being turned on, because each button of the battery remote control moves independently. However, there are many defects that need to be overcome in the multi-button wireless switch powered by a micro-generator. First, when there are too many buttons, the pressing force and stroke of the buttons far from the generator are different. How to ensure that the pressing force of each button is consistent? Second, in the process of pressing a button, it is necessary to generate a corresponding button command and press the generator synchronously to generate electricity. How to ensure that the command and electricity are generated at the same time when any button is pressed? Third, in order to achieve a short-stroke pressing feel like a battery remote control, how to ensure that each button can be accurately turned on and drive the generator to generate electricity within the range of 0.2-0.5 mm when the button is pressed? The stroke of the micro switch that generates the command is several times different from the driving stroke of the generator. In the case of the linkage between the two, how to ensure that each button at different positions can synchronously and accurately drive the micro switch and the generator each time when the operation is performed, without generating a feeling of two setbacks? Furthermore, while keeping the movement stroke of each button small, how to ensure that when any button is pressed, the adjacent buttons will not generate wrong commands due to the linkage of the device. The patent with publication number CN110071617 provides a multi-key same-program switch. This solution has three obvious defects. First, it will produce two setbacks during operation, and the command switch b and the micro-generator c will make a noise once respectively, resulting in a double sound. Second, the movement strokes of the command switch b and the micro-generator c are superimposed, which results in a too long stroke during the pressing operation, the key sinks too deep, and the feeling of stepping on the air is strong, which does not conform to user habits and has poor practicality. Third, since the conduction stroke of each command switch is about 0.5 mm, and the stroke of the micro-generator is between 2-5 mm, when there are many keys, the total pressing stroke is large and the pressing force is much greater than that of the traditional remote control, which easily causes the adjacent keys to be pulled and linked to trigger by mistake and generate erroneous commands.

[0005] Therefore, although the multi-button self-generating switch in the prior art solves the power supply problem, its operating experience is still relatively poor, far inferior to the operating feel of a battery remote control. This is an obstacle to the popularization and application of such products. The above-mentioned multiple defects require a complete design solution to solve them in a unified manner.

[0048] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0049] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0050] It is worth mentioning that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple. Therefore, the term "one" should not be understood as a limitation on quantity.

[0051] The utility model provides a passive multi-key switch with touchless conversion, wherein the passive multi-key switch with touchless conversion is powered by a micro-generator based on the principle of electromagnetic induction, and the corresponding micro-generator is driven in linkage based on the operation of a key of the passive multi-key switch with touchless conversion to generate electric energy, so no additional battery or external power supply is required.

[0052] Furthermore, the passive multi-key switch with touchless conversion has a plurality of buttons and command switches corresponding to each button, wherein the operation of each button can drive the micro-generator in a linked manner, and each command switch is in an on state before the corresponding button is operated, and remains in the on state when the corresponding button is operated. In this way, the linkage structure design between the button and the micro-generator does not need to consider the stroke and linkage of the command switch corresponding to the button, so that the force change of the button when being operated is directly related to the driving force of the micro-generator, so that the operation feel of touchless conversion can be obtained.

[0053] In order to understand the technical concept of the present invention at the principle level, please refer to the accompanying drawings of the specification of the present invention. Figure 2A and Figure 2B As shown, the structural principle of a passive multi-key switch with non-touch conversion according to an embodiment of the utility model is illustrated, wherein the passive multi-key switch with touch conversion includes a plurality of keys 20, a command switch 30 corresponding to each of the keys 20, a command switch substrate 40 and a micro-generator 50, wherein each of the command switches 30 is arranged on the command switch substrate 40, and the micro-generator 50 is arranged to be driven in linkage based on the movement of the command switch substrate 40.

[0054] Corresponds to Figure 2A In the initial state where the keys 20 of the passive multi-key switch without touch conversion are not pressed, the keys 20 abut against the top of the command switch substrate 40, and the command switch substrate 40 is linked to the micro-generator 50. In particular, in order to reduce the pressing stroke of the passive multi-key switch without touch conversion, that is, to reduce the pressure of the passive multi-key switch with touch conversion, Figure 1BThe stroke corresponding to the stroke b in the stroke b, each of the command switches 30 is set to a pre-pressed or pre-contacted state in the initial state of the passive multi-key switch without touch conversion, so that the driving gap between the key 20 and the command switch substrate 40 is close to 0. In some embodiments, a slight gap that is not easily perceived by the hand is allowed to be retained, wherein the pre-pressed state (or pressed / contacted state) refers to the command switch 30 being subjected to the joint force of the key 20 and the command switch substrate 40.

[0055] Specifically, taking the instruction switch 30 as an example of a membrane switch or a silicone switch with at least two electrode structures, when the instruction switch 30 adopts a silicone switch, the electrode of the silicone switch for collecting instruction information and connected to the corresponding MCU is set on the instruction switch substrate 40, and when the electrode is turned on by the conductive silicone, the MCU will generate a preset instruction. Correspondingly, in the description of the utility model, the conductive silicone is used as the first electrode, and the electrode set on the instruction switch substrate 40 is used as the second electrode, and the second electrode is connected to the I / O interface of the MCU of the wireless transmitting circuit. In the initial state of the passive multi-key switch with no touch conversion, the first electrode and the second electrode are abutted and turned on. The advantage of this setting is that the pressing stroke can be reduced by about 1 mm, giving the user a pressing feel similar to that of operating a battery remote control, and also reducing the thickness of the product. However, due to the large number of buttons and the influence of manufacturing tolerances, a subtle gap between the first electrode and the second electrode is allowed to be imperceptible, as long as the stroke is not significantly increased to affect the experience.

[0056] Corresponds to Figure 2BWhen any of the keys 20 is pressed, the pressed key 20 pushes the command switch substrate 40 to move in the pressing direction of the key 20 until the command switch substrate 40 triggers the micro-generator 50 to generate electrical energy, thereby forming a safety area D between the keys 20 that are not pressed and the corresponding command switch 30. Since the command switch 30 is pre-stressed in the initial state of the passive multi-key switch without touch conversion, the command switch substrate 40 can be driven immediately based on the pressing of any of the keys 20 and has a movement stroke close to the pressing stroke of the pressed key 20, so that the space size of the safety area D can be guaranteed. The advantage of such a setting is that even if the switch housing or the corresponding key carrier is deformed, or the command switch substrate 40 is deformed due to a large pressing force or a large assembly difference, the space of the safety area D can ensure that the other unpressed command switches 30 have sufficient isolation space and will not be triggered by mistake. It is worth mentioning that when the command switch 30 uses a silicone contact switch, the larger the safety area D, the more stable the passive multi-key switch with no touch-sensing conversion is when used in a humid environment. For example, when the passive multi-key switch with no touch-sensing conversion is used in a humid environment, the resistivity of the air decreases, and the circuit board is easily affected by moisture. If the spacing between the contacts of the silicone contact switch is not enough, it is easy to cause a false trigger event. The structure of the utility model solves this problem.

[0057] That is to say, the micro-generator 50 is configured to be driven in linkage based on the movement of the command switch substrate 40, wherein in the initial state where each of the buttons 20 is not pressed, each of the command switches 30 is pressed by the corresponding button 20, so that when any of the buttons 20 is pressed, the command switch 30 corresponding to the button 20 is maintained in the state of being pressed by the button 20, so that the command switch substrate 40 can be driven based on the pressing of the button 20 and drive the micro-generator 50 in linkage, and at the same time, the other buttons 20 are maintained in the initial state of not being pressed, and the safety area D can be formed between the command switch substrate 40 and the corresponding command switch 30 based on the movement, then the safety area D can be increased based on the pressing of any of the buttons 20, so that the command switches 30 corresponding to the other buttons 20 are away from the corresponding button 20 in the pressing direction, and the movement stroke of the command switch substrate 40 generated by the pressing of the corresponding button 20 is close to the pressing stroke of the button 20, so that the space size of the safety area D can be guaranteed.

[0058] Specifically, when the command switch 30 is configured to adopt a silicone contact switch, the corresponding button 20 has the first electrode, and the command switch 30 has the second electrode. In the initial state where each button 20 is not pressed, each command switch 30 is pressed by the corresponding button 20 to form a structural form in which the corresponding first electrode and the second electrode are close to or in contact with each other, so that when any button 20 is pressed, the first electrode of the button 20 can contact the corresponding second electrode so that the command switch substrate 40 can be driven based on the pressing of the button 20 and the micro-power generation device 50 can be driven in conjunction, while the second electrode of the command switch 30 corresponding to other buttons 20 moves away from the first electrode of the corresponding button 20 as the safety area D increases.

[0059] It is worth mentioning that, in order to intuitively understand the concept of the present invention, when the command switch 30 adopts a silicone switch, the description method of the first electrode and the second electrode is adopted; and when the command switch 30 does not adopt a silicone switch, in terms of function and effect, the first electrode and the second electrode are actually the relationship between the positions of the parts, and the first electrode corresponds to Figures 3 to 11 The structure shown is the abutment column 22 of the button 20 abutting against the command switch 30, and the second electrode is the driving end 31 of the command switch 30 abutted by the button 20; in the initial state of the passive multi-key switch without touch conversion, the abutment column 22 abuts against the driving end 31.

[0060] When corresponding to Figures 3 to 11 When the illustrated structure uses a micro detection switch as the command switch 30, the safety area D refers to the distance from the key 20 to the micro detection switch driving end 31. Simply put, the passive multi-key switch without touch conversion will make the trigger distance of the command switch 30 farther and farther during the pressing process, thereby reducing the pressing stroke and preventing the phenomenon of false triggering. It can be understood that the "far" referred to in the present utility model is significantly increased or doubled relative to the initial state of the micro distance.

[0061] Further, Figure 2BTaking a silicone contact switch as the command switch 30 as an example, when a silicone contact switch is used as the command switch 30, the button 20 pushes the command switch substrate 40 to move, so that the distance between the contact of the unpressed button 20 and the contact of the corresponding command switch 30 becomes farther and farther, and the gap becomes larger and larger. Specifically, when the button 20 reaches the predetermined position, the distance between the contact of the unpressed button 20 and the contact of the corresponding command switch 30 can reach 0.5-2 mm, thereby completely solving the problem that when one button 20 is pressed, the adjacent buttons 20 are easily pulled and linked and triggered by mistake. In other words, if the button 20 is pressed deeper, the generation of the command is more reliable and less susceptible to interference. Therefore, except for the command switch 30 corresponding to the pressed button 20 that continues to maintain the working state, the other command switches 30 are released from the pre-working state, that is, converted into the non-working state. The non-working state refers to a state opposite to the normal state or a state opposite to the pre-working state.

[0062] The button 20 continues to push the command switch substrate 40 to move within the range of the aforementioned stroke C until the command switch substrate 40 drives the micro-generator 50 to generate electrical energy. When the micro-generator 50 generates electrical energy, since only the command switch 30 pressed by the button 20 is in a conducting state, and the other command switches 30 that are not pressed are in a disconnected state, at the moment of power supply, the corresponding wireless transmitting circuit can transmit wireless control information corresponding to the pressed command switch 30, wherein the wireless transmitting circuit is arranged on the command switch substrate 40 to reduce the volume of the utility model.

[0063] It should be noted that the above disclosure is an embodiment of the command switch 30 using a normally closed switch. In practical applications, the command switch 30 can be composed of various types of small on-off components, such as a micro switch, a detection switch, a silicone contact switch, a toggle switch, a touch switch, etc. These switches include two types of contacts, normally open or normally closed. According to the different structures of these switches and the needs of the microprocessor in the circuit for level setting, the pre-working state of these command switches 30 includes one of fully on or fully off.

[0064] For example, when a normally open micro switch under pressure is used as the command switch 30, all switches are in a normally open state under normal conditions. Only when the button 20 pushes the command switch substrate 40 to move, except for the pressed command switch 30 which continues to be in a normally open state, the other command switches 30 are in a conducting state. The microprocessor identifies different levels, so that the wireless transmitting circuit generates a command corresponding to the pressed command switch 30. Therefore, which micro switch is used as the command switch 30 depends on the circuit's demand for levels. If a high level trigger is required to generate a command, a normally closed micro switch is used, which is always in a conducting state when pressed. If a low level trigger is required to generate a command, a normally open micro switch is used, which is always in a disconnected state when pressed.

[0065] It should be pointed out that the conductive rubber switch of the traditional battery-powered remote control is in a gap-disconnected state under normal conditions and will only be turned on when the corresponding conductive rubber switch is pressed, and its circuit board is fixed and only the conductive rubber switch moves, and each conductive rubber switch is independent, so there is no technical defect described in the utility model; while the buttons of the self-generating remote control in the prior art need to move, the conductive rubber switches located at different positions need to move, the circuit board located under the conductive rubber switch needs to move, the corresponding driving balance mechanism needs to move, and the micro-generator also needs to move, so a complete technical solution must be used to simultaneously solve the multiple technical defects mentioned above.

[0066] Further, referring to the drawings of the specification of the utility model Figures 3 to 11As shown, a passive multi-key switch without touch conversion according to the above structural principle of the utility model is schematically illustrated, wherein the passive multi-key switch with touch conversion includes a key carrier 10, a plurality of keys 20, a command switch 30 corresponding to each of the keys 20, a command switch substrate 40 and a micro-power generation device 50, wherein the key carrier 10 has a plurality of key accommodating positions 101, wherein each of the keys 20 is supported by a deformable support body 11 in the key accommodating position 101 and can be pressed and operated, wherein each of the command switches 30 is arranged on the command switch substrate 40, and the micro-power generation device 50 is arranged to be driven in linkage based on the movement of the command switch substrate 40, wherein before the keys 20 are operated, each of the command switches 30 is pressed by the corresponding keys 20 and is in a conducting state. state, and when any of the buttons 20 is operated, the command switch 30 corresponding to the button 20 is maintained in a conductive state pressed by the button 20, and the button 20 drives the command switch substrate 40 to move in the operated direction to drive the micro-power generation device 50 in conjunction, while the other buttons 20 are supported by the corresponding deformable support bodies 11 and maintained in the original positions that are not operated, so that the command switches 30 corresponding to the other buttons 20 can be self-reset based on the movement of the command switch substrate 40 and be in a disconnected state, so that the selection of the corresponding remote control command and the driving of the micro-power generation device 50 can be realized based on the operation of any of the buttons 20 without additionally driving the command switch 30 corresponding to the button 20 to be turned on.

[0067] That is to say, in the passive multi-key switch with touchless conversion of the present invention, the linkage structure design between the button 20 and the micro-generator 50 does not need to consider the stroke and linkage of the command switch corresponding to the button 20, that is, the stroke of the button 20 is directly related to the driven stroke of the micro-generator 50, and before the micro-generator 50 is driven to generate electricity based on the operation of the corresponding button 20, the operation of the button 20 does not need to additionally drive the command switch 30 corresponding to the button 20 to turn on, which correspondingly avoids the requirement of stably achieving the high stroke requirement of the button 20, and is conducive to shortening the stroke of the button 20 to reduce the thickness of the passive multi-key switch with touchless conversion.

[0068] In addition, before the micro-generator 50 is driven to generate electricity based on the operation of the corresponding button 20, the operation of the button 20 does not need to drive the command switch 30 corresponding to the button 20 to be turned on, so as to avoid the need for stably achieving the high stroke requirement for the button 20. The stroke of the button 20 and the stroke of the micro-generator 50 driven to generate electricity can be shortened to reduce the differences in operating stroke and force of each button 20 due to the different distribution positions relative to the micro-generator 50, thereby facilitating a comfortable operating feel.

[0069] In particular, the linkage structure design between the button 20 and the micro-generator 50 does not need to consider the stroke and linkage of the command switch 30 corresponding to the button 20. Therefore, the size and position of the force-bearing surface on the button 20 used to linkage drive the micro-generator 50 are not subject to the structural restrictions of the command switch 30 corresponding to the button 20, and the reliability and stability of the linkage structure between the button 20 and the micro-generator 50 can be ensured by increasing the force-bearing surface and / or increasing the force points.

[0070] Specifically, in this embodiment of the utility model, each of the buttons 20 has a mutually independent pressing position 201 and a driving position 202, that is, the button 20 is pressed against the command switch 30 at the pressing position 201, and drives the command switch substrate 40 by applying force to the command switch substrate 40 at the driving position 202, so that the size and position of the driving position 202 on the button 20 for linkage driving the micro-generator 50 are not restricted by the structure of the command switch 30 corresponding to the button 20, and the reliability and stability of the linkage structure between the button 20 and the micro-generator 50 can be ensured by increasing the force surface and / or the force points.

[0071] Furthermore, in this embodiment of the utility model, the key 20 includes a keycap 21, an abutment column 22 and at least one driving column 23, wherein the abutment column 22 and the driving column 23 extend in the same direction from the keycap 21 to form the pressing position 201 on the end surface of the abutment column 22, and the driving position 202 on the end surface of the driving column 23, corresponding to that before the key 20 is operated, each of the command switches 30 is pressed by the abutment column 22 of the corresponding key 20 and is in a conducting state, and when any of the keys 20 is operated, the command switch 30 corresponding to the key 20 is maintained in the conducting state pressed by the abutment column 22 of the key 20, and the key 20 drives the command switch substrate 40 to move in the operated direction by the driving column 23, thereby driving the micro power generation device 50 in a linked manner.

[0072] Therefore, the number and size of the driving columns 23 of the same button 20 are not restricted by the structure of the command switch 30 corresponding to the abutment column 22, but can increase the force-bearing surface between the button 20 and the command switch substrate 40 and / or increase the force-bearing points between the button 20 and the command switch substrate 40 by increasing the end surface of the driving column 23 and / or increasing the number of the driving columns 23, which is beneficial to ensure the smooth driving of the button 20 on the command switch substrate 40 and ensure the reliability and stability of the linkage structure between the button 20 and the micro-power generation device 50.

[0073] Specifically, in this embodiment of the utility model, the number of the driving columns 23 is two, and the abutment column 22 is located between the two driving columns 23, so as to increase the force points between the button 20 and the command switch substrate 40 while increasing the force surface between the button 20 and the command switch substrate 40, and further based on the structural design that the abutment column 22 is located between the two driving columns 23, the button 20 is ensured to drive the command switch substrate 40 smoothly, thereby ensuring the reliability and stability of the linkage structure between the button 20 and the micro-power generation device 50.

[0074] Optionally, in some embodiments of the utility model, the driving column 23 is arranged in the form of a cylindrical column surrounding the abutment column 22, for example but not limited to a square and circular cylindrical column form, so that it is also possible to increase the force surface between the button 20 and the command switch substrate 40 while increasing the force points between the button 20 and the command switch substrate 40, and based on the structural design that the driving column 23 is arranged in the form of a cylindrical column surrounding the abutment column 22, the smooth driving of the button 20 on the command switch substrate 40 is ensured, thereby ensuring the reliability and stability of the linkage structure between the button 20 and the micro-power generation device 50.

[0075] It is worth mentioning that when any of the buttons 20 is operated, the other buttons 20 are supported by the corresponding deformable support body 11 and maintained in the original position that is not operated, that is, the deformable support body 11 only needs to be able to support the corresponding button 20 to prevent the button 20 from sinking due to its own weight in the operated direction, and the corresponding deformable support body 11 only needs to be able to deform when the corresponding button 20 is operated and to be able to restore to its original shape under the action of itself or external force under the requirement of having a certain supporting force. The specific structural form and material of the corresponding deformable support body 11 do not constitute a limitation to the present invention. For example, the deformable support body 11 can adopt a structural design that can undergo elastic deformation and restore to its original shape under its own action, such as a spring, a silicone cap, and an elastic bracket, or it can also adopt other structural designs that can undergo non-elastic deformation and restore to its original shape under the action of external force.

[0076] In order to prevent the corresponding key 20 from being separated from the key carrier 10 in the opposite direction of the operation direction due to its own weight or the supporting force of the deformable support body 11, the key 20 is preferably supported by the corresponding deformable support body 11 in the key accommodating position 101 in a state of being movably embedded in the key carrier 10, so as to prevent the corresponding key 20 from being separated from the key carrier 10 in the opposite direction of the operation direction due to its own weight or the supporting force of the deformable support body 11, and at the same time, when the keycaps 21 of each of the keys 20 on the key carrier 10 have a high degree of consistency, the accuracy requirement on the deformable support body 11 can be reduced.

[0077] It is worth mentioning that in order to realize the movable embedding of the key 20 in the key carrier 10, the corresponding embedding structure on the key 20 can be independently set relative to the abutment column 22 and the driving column 23. For example, corresponding to this embodiment of the present invention, an embedding column 24 is set on the key 20, and an embedding hole 12 matching the embedding column 24 is set on the key carrier 10 to realize the movable embedding of the key 20 in the key carrier 10, wherein the embedding column 24 extends from the key cap 21 in the same direction as the abutment column 22 and the driving column 23, and a hook 241 is formed at the end of the embedding column 24, corresponding to the state where the embedding column 24 passes through the embedding hole 12 of the key carrier 10, so that the hook 241 can be limited by the embedding hole 12 in the opposite direction of the operation direction of the corresponding key 20, thereby realizing the movable embedding of the key 20 in the key carrier 10.

[0078] In addition, the corresponding embedding structure on the button 20 can also be integrated on the abutment column 22 or the driving column 23, such as a hook is further provided on the abutment column 22 or the driving column 23, and an embedding hole matching the hook is provided on the button carrier 10, based on the limiting of the hook on the abutment column 22 or the driving column 23 by the embedding hole in the opposite direction of the operation direction of the corresponding button 20, the button 20 is movably embedded in the button carrier 10, and the present invention is not limited to this.

[0079] It is worth mentioning that, under normal circumstances, the corresponding remote control command corresponds to the state of a single command switch 30, and the command switch 30 is usually a normally open (disconnected) type command switch. Therefore, in this embodiment of the utility model, when the command switch 30 is abutted by the abutting column 22 of the corresponding button 20, the command switch 30 is in a conducting state. Based on the structural principle of the utility model, on the one hand, since the corresponding remote control command can also correspond to the combined state of multiple command switches 30 based on a specific program / circuit design, and on the other hand, since the command switch 30 can also adopt a normally closed command switch, in other embodiments of the utility model, when the command switch 30 is abutted by the abutting column 22 of the corresponding button 20, the command switch 30 can also be in a disconnected state, and the selection of the remote control command corresponding to the button 20 can still be realized by operating the button 20 based on the structural principle of the utility model.

[0080] That is to say, in the above description of the present invention, the description of the on state and the off state of the command switch 30 is only for the convenience of understanding the state transition of the command switch, and it does not constitute a limitation on the specific state of the command switch. The on state of the command switch 30 can be equivalently expressed as the first state of the command switch 30, and the off state of the command switch 30 can be equivalently expressed as the second state of the command switch 30.

[0081] Furthermore, the passive multi-key switch with touchless conversion also includes a bottom shell 60 and a substrate carrier 70, wherein the key carrier 10 is fixed to the bottom shell 60, for example but not limited to being fixed by snapping, gluing, and screwing, wherein the command switch substrate 40 is carried on the substrate carrier 70, and the micro-power generation device 50 is arranged on the bottom shell 60 or the substrate carrier 70, and is arranged to be driven based on the relative movement between the substrate carrier 70 and the bottom shell 60, so that the micro-power generation device 50 can be driven in linkage based on the movement of the command switch substrate 40.

[0082] Specifically, the micro-generator 50 includes a driving arm 51, wherein the micro-generator 50 is configured to generate electrical energy based on a pivotal drive of the driving arm 51 that meets a certain stroke requirement, and the corresponding driving arm 51 is configured to be pivotally driven based on the relative movement between the substrate carrier 70 and the bottom shell 60.

[0083] Furthermore, the passive multi-key switch with touchless conversion also includes an elastic reset member 80, wherein the elastic reset member 80 is configured to store potential energy by elastically deforming based on the relative movement between the substrate carrier 70 and the bottom shell 60, corresponding to the structural state in which the command switch substrate 40 is carried on the substrate carrier 70. When the button 20 is operated by force, the command switch substrate 40 is driven by the button 20 to drive the substrate carrier 70 to move relative to the bottom shell 60. At the same time, the elastic reset member 80 stores potential energy by elastically deforming based on the relative movement between the substrate carrier 70 and the bottom shell 60, and when the force on the button 20 is released, the elastic reset member 80 resets and drives the substrate carrier 70 and the driving arm 51, so that the command switch substrate 40 and the button 20 are reset synchronously based on the reset of the substrate carrier 70.

[0084] Specifically, when the micro-generator 50 is arranged on the substrate carrier 70 in accordance with this embodiment of the present invention, the elastic reset member 80 can be arranged on the micro-generator 50 and the drive arm 51 elastically supported on the micro-generator 50 in the form of a torsion spring in accordance with this embodiment of the present invention, or can be elastically supported between the substrate carrier 70 and the drive arm 51 in the form of a torsion spring or a spring, and the bottom shell 60 is provided with a drive portion 61 abutting against the drive arm 51, so that when the button 20 is operated by force to drive the command switch substrate 40, the substrate The carrier 70 is driven by the command switch substrate 40 to move relative to the bottom shell 60. The driving portion 61 of the bottom shell 60 drives the driving arm 51 based on the relative movement between the substrate carrier 70 and the bottom shell 60. The elastic reset member 80 elastically supported on the driving arm 51 undergoes elastic deformation and stores potential energy when the driving arm 51 is driven. When the force applied to the button 20 is released, the elastic reset member 80 resets and drives the substrate carrier 70 and the driving arm 51. The command switch substrate 40 and the button 20 are reset synchronously based on the reset of the substrate carrier 70.

[0085] Similarly, when the micro-generator 50 is disposed on the bottom shell 60, the elastic reset member 80 can be disposed on the micro-generator 50 and elastically supported on the driving arm 51 in the form of a torsion spring, or can be elastically supported between the bottom shell 60 and the driving arm 51 in the form of a torsion spring or a spring, and the corresponding substrate carrier 70 is provided with a driving portion that abuts against the driving arm 51, so that when the button 20 is operated by force to drive the command switch substrate 40, the substrate carrier 70 is driven by the command switch substrate 40 to move relative to the bottom shell 60. The bottom shell 60 moves, and the driving portion of the substrate carrier 70 drives the driving arm 51 based on the relative movement between the substrate carrier 70 and the bottom shell 60. The elastic reset member 80 elastically supported on the driving arm 51 stores potential energy due to elastic deformation caused by the driving of the driving arm 51. When the force applied to the button 20 is released, the elastic reset member 80 resets and drives the substrate carrier 70 and the driving arm 51, and the command switch substrate 40 and the button 20 are reset synchronously based on the reset of the substrate carrier 70.

[0086] In addition, when the micro-generator 50 is arranged on the substrate carrier 70 and the driving arm 51 is limited and clamped in the bottom shell 60, the elastic return member 80 can be elastically supported between the bottom shell 60 and the substrate carrier 70 or the micro-generator 50 in the form of any one of a torsion spring, a spring and an elastic bracket; and when the micro-generator 50 is arranged on the bottom shell 60 and the driving arm 51 is limited and clamped in the substrate carrier 70, the elastic return member 80 can be elastically supported between the substrate carrier 70 and the bottom shell 60 or the micro-generator 50 in the form of any one of a torsion spring, a spring and an elastic bracket.

[0087] It is worth mentioning that, in the state where the elastic return member 80 is elastically supported between the substrate carrier 70 and the bottom shell 60, compared with being elastically supported on the driving arm 51, on the one hand, it can avoid overload of the driving arm 51, which corresponds to reducing the precision requirements for the corresponding force-bearing structure, while being beneficial to ensuring the structural stability and service life of the passive multi-key switch with touchless conversion, and on the other hand, it can also make the shape and quantity of the elastic return member 80 not subject to the structural restrictions of the driving arm 51, and then based on the corresponding shape and quantity of the elastic return member 80, it can increase the force-bearing surface between the elastic return member 80 and the substrate carrier 70 and the bottom shell 60, and / or increase the force-bearing points between the elastic return member 80 and the substrate carrier 70 and the bottom shell 60, which is correspondingly beneficial to ensuring the smoothness of the relative movement between the substrate carrier 70 and the bottom shell 60.

[0088] Furthermore, the passive multi-key switch with touchless conversion also includes a balanced linkage component 90 mounted between the substrate carrier 70 and the bottom shell 60. Based on the corresponding structural design of the balanced linkage component 90, when the command switch substrate 40 carried on the substrate carrier 70 is driven by the corresponding key 20, the consistency of the movement stroke of the command switch substrate 40 is ensured, and the consistency of the stroke and force of each key 20 when being operated is correspondingly ensured, which is conducive to obtaining a comfortable operating feel.

[0089] Specifically, the balancing linkage assembly 90 includes a first balancing linkage frame 91 and a second balancing linkage frame 92, wherein the first balancing linkage frame 91 includes a first balancing beam 911 and two first linkage arms 912 extending in the same direction from both ends of the first balancing beam 911, and the second balancing linkage frame 92 includes a second balancing beam 921 and two second linkage arms 922 extending in the same direction from both ends of the second balancing beam 921, wherein the first balancing linkage frame 91 and the second balancing linkage frame 92 are pivotally arranged on the substrate carrier 70 or the bottom shell 60, wherein the first balancing linkage frame 91 is pivotally arranged in a manner that the pivot axes of the two first linkage arms 912 coincide with each other so that the two first linkage arms 912 can pivot synchronously, and the second balancing linkage frame 92 includes a second balancing beam 921 and two second linkage arms 922 extending in the same direction from both ends of the second balancing beam 921. The linkage frame 92 is pivotally arranged in such a way that the pivot axes of the two second linkage arms 922 coincide with each other so that the two second linkage arms 922 can pivot synchronously, and the ends of the two first linkage arms 912 are respectively linked and docked with the ends of the two second linkage arms 922, so that the movement of the first balance beam 911 and the second balance beam 921 in the operating direction of the button 20 can be synchronized, so that when the command switch substrate 40 carried on the substrate carrier 70 is driven by the corresponding button 20, the consistency of the movement stroke of the command switch substrate 40 is guaranteed, thereby reducing the differences in operating stroke and force of each button 20 due to the different distribution positions relative to the micro-power generation device 50, which is conducive to obtaining a comfortable operating feel.

[0090] It is worth mentioning that, in the state where the micro-generator 50 is arranged on the substrate carrier 70, and the driving arm 51 is limited and clamped on the bottom shell 60; and in the state where the micro-generator 50 is arranged on the bottom shell 60, and the driving arm 51 is limited and clamped on the substrate carrier 70, the elastic reset member 80 is optionally arranged in the form of a torsion spring and elastically supported between the first balance linkage frame 91 and the second balance linkage frame 92 of the balance linkage assembly 90, so that the balance linkage assembly 90 is erected on The state between the substrate carrier 70 and the bottom shell 60 is elastically supported between the substrate carrier 70 and the bottom shell 60 with the balancing linkage assembly 90 as the force-conducting medium. In this way, relative to elastic support on the driving arm 51, it is possible to avoid overload of the driving arm 51, and relative to direct support between the substrate carrier 70 and the bottom shell 60, it is possible to increase and balance the force points between the substrate carrier 70 and the bottom shell 60, which is beneficial to ensure the stability of the relative movement between the substrate carrier 70 and the bottom shell 60.

[0091] Furthermore, in this embodiment of the present invention, at two ends of the first linkage arm 912 and the second linkage arm 922 linked and docked therewith, one end is provided with a bar slide rail, and the other end is provided with a slider suitable for sliding and rotating in the bar slide rail, so that the linkage docking between the first linkage arm 912 and the corresponding second linkage arm 922 is realized when the slider is placed on the bar slide rail, and when the first linkage arm 912 is linked and docked with the corresponding second linkage arm 922, the first balance linkage frame 91 and the second balance linkage frame 92 can still pivot to realize the synchronous movement of the first balance beam 911 and the second balance beam 921 in the operating direction of the button 20.

[0092] Furthermore, in this embodiment of the present invention, the first balance linkage frame 91 and the second balance linkage frame 92 are pivotally arranged on the bottom shell 60, the two ends of the first balance beam 911 are slidably and rotatably arranged on the substrate carrier 70, and the two ends of the second balance beam 921 are slidably and rotatably arranged on the substrate carrier 70, so that the substrate carrier 70 can maintain balance in the operating direction of the button 20 based on the synchronous movement of the first balance beam 911 and the second balance beam 921, correspondingly, when the command switch substrate 40 carried on the substrate carrier 70 is driven by the corresponding button 20, the consistency of the movement stroke of the command switch substrate 40 is ensured.
