Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of furniture control, and particularly relates to a patting type control device and an electric furniture. BACKGROUND

[0002] With the development of technology, some furniture (for example, an electric bed, an electric sofa, etc.) can be deformed to change a sitting or lying posture, thereby enriching the use experience. In addition, some electric beds, electric sofas or other furniture can realize functions such as heating and massage. In order to realize the control of the furniture, a control device needs to be provided in a matched manner. Button control is a relatively common control device. For example, a button can be arranged at a fixed position of a sofa to realize control by pressing the button.

[0003] The button needs to be exposed outside the furniture to be contacted and pressed by a finger. Therefore, a hard area usually needs to be left on the furniture to install a key and a circuit board and other components. The hard area affects the comfort of the furniture and the integrity of the leather or cloth covering the furniture. In addition, the size of the button is relatively small, and the button position needs to be found for operation when the button is pressed. The operation is not convenient, especially for the elderly.

[0004] Therefore, it is necessary to improve the prior art to overcome the defects in the prior art.

[0005] The above content is only used to help understand the technical solutions of the present application and does not constitute an acknowledgement of the above as prior art. SUMMARY

[0006] The present application aims to provide a patting type control device and an electric furniture to conveniently realize a control function.

[0007] To achieve the above-mentioned application purposes, in one aspect, the present application provides a patting type control device, comprising:

[0008] a hose, the hose being elastic and not completely closed;

[0009] a microphone connected to the hose and located at least partially in the hose for detecting sound waves in the hose; and

[0010] a control circuit electrically connected to the microphone.

[0011] Further, the hose can balance the internal pressure and the external pressure within 0.2s to 1s after being patted.

[0012] Further, the microphone is arranged at one end of the hose in the length direction of the hose.

[0013] the other end of the hose in the length direction is closed; or

[0014] The other end of the hose along its length is open, and the cross-sectional area at the opening of the hose is no greater than 20 mm².

[0015] Furthermore, microphones are provided at both ends of the hose along its length. The control circuit generates different control signals based on the phase difference of the induction signals generated by the two microphones, so as to achieve different control functions according to different tapping positions.

[0016] Furthermore, the hose has a non-deformable portion that cannot be deformed by being slapped.

[0017] The microphone is provided at only one end of the hose along its length. The control circuit determines the position where the hose is being hit based on the sensing signal generated by the microphone and generates different control signals accordingly.

[0018] Furthermore, the thickness B of the internal space of the hose in the striking direction is not less than 2mm, the material of the hose is silicone, rubber, PVC, acrylate or PET, the wall thickness is 0.1mm~3.0mm, and the outer contour of the hose cross-section is circular or rectangular or flat.

[0019] Furthermore, the hose is provided with a vent hole that communicates with the outside, and the cross-sectional area of ​​a single vent hole is no greater than 20 mm².

[0020] Furthermore, the hose is arranged in a straight line; or,

[0021] The hose is arranged in a curved configuration, comprising at least two opposing portions.

[0022] Furthermore, the hose includes at least one meandering portion, the meandering portion including at least two opposing portions, the meandering portion being configured such that when the meandering portion is patted once, at least two opposing portions are patted simultaneously by one hand.

[0023] Furthermore, the tapping control device includes a hose fixing assembly, which includes a base plate and a limiting member connected to the base plate, forming a space between the limiting member and the base plate for the hose to pass through.

[0024] Furthermore, the limiting member is made of a flexible material.

[0025] On the other hand, the present invention proposes an electric furniture, comprising: a tapping control device as described above, the tapping control device being used to control the deformation of the electric furniture, the electric furniture including a flexible covering body exposed to the outside, the tapping control device being located within the flexible covering body.

[0026] Compared with existing technologies, the present invention has the following advantages: According to at least one embodiment of the present invention, the tapping control device includes a flexible tube, a microphone, and a control circuit. The flexible tube is elastic and not completely sealed; the microphone is connected to the flexible tube and is at least partially located inside the flexible tube for detecting sound waves inside the flexible tube; the control circuit is electrically connected to the microphone. During control, simply tapping the flexible tube generates a corresponding control signal, making operation simpler and easier, especially for the elderly. Furthermore, the flexible tube can be arranged over a wide area, and control can be achieved through simple tapping in a general direction, making it more convenient. Further, the flexible tube is low in cost and has the characteristic of being able to be bent at will, making it more adaptable to the installation environment and easier to install. In addition, the flexible tube is not a rigid object; when installed on furniture such as sofas or beds, it has little impact on the comfort of the furniture, and the tapping control device can still be used normally even when encased in the flexible covering layer of the furniture, without needing to be exposed, thus not affecting aesthetics.

[0046] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0047] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0048] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0049] like Figure 1 and Figure 2 As shown, some embodiments of the present invention propose a tapping control device, including a hose 1, a microphone 3, and a control circuit.

[0050] The inside of the flexible tube 1 forms an air-containing space 11. The microphone 3 is connected to the flexible tube 1 and is at least partially located inside the flexible tube 1, used to detect sound waves inside the flexible tube 1. The flexible tube 1 is elastic and not completely sealed. When the flexible tube 1 is squeezed or hit, it can undergo elastic deformation and expel gas outward in the process, so that the internal and external air pressure is balanced. Conversely, when the squeezing or hitting ends, the flexible tube 1 can rebound under the elastic force of its own material and return to its initial state. In this process, external gas is drawn into the flexible tube 1, and the internal and external air pressure is balanced again.

[0051] It is understandable that the gas fluctuations during the deformation of the hose 1 will cause changes in the sound waves. The microphone 3 can detect these changes in the sound waves and generate corresponding electrical signals. The control circuit is electrically connected to the microphone 3 and is used to receive the electrical signals generated by the microphone 3 and calculate the corresponding control signals.

[0052] When the hose 1 is tapped, the gas inside the hose 1 is expelled under pressure. After tapping, the hose 1 rebounds under its own elasticity and draws in gas. The change in internal air pressure in the hose 1 causes a change in sound waves. The microphone 3 detects the sound waves and generates a corresponding electrical signal. The control circuit can calculate the corresponding control signal based on the different characteristics of the electrical signal, thereby controlling the external device to achieve the corresponding function. For example, tapping the hose 1 once or twice consecutively can control the electric furniture to switch between different forms, while tapping the hose 1 multiple times consecutively can control the electric furniture to stop deforming in an emergency.

[0053] Understandably, when controlling the system, simply tapping the flexible hose 1 generates the corresponding control signal, making it simpler and easier to operate, especially for the elderly. Furthermore, the flexible hose 1 can be deployed over a wide area, allowing for control through simple tapping in a general direction, making it even more convenient. In addition, the flexible hose 1 is low-cost and flexible, making it more adaptable to different installation environments and easier to install.

[0054] In addition, since the flexible hose 1 is not a rigid object, when it is installed on furniture such as sofas or beds, it has little impact on the comfort of the furniture. Furthermore, the tapping control device can be used normally even when it is encased in the flexible covering layer of the furniture, without needing to be exposed, thus not affecting the aesthetics.

[0055] Understandably, by setting the hose 1 to a partially closed form, the hose 1 does not have to be in its original state (unpressed state) to work properly. Even if the hose 1 is initially under pressure (for example, when it is squeezed when wrapped in the flexible covering layer of furniture), the hose 1 still has a certain volume inside, and the air pressure inside the hose 1 is consistent with the external atmospheric pressure. When it is hit, it can still generate a reliable impact signal, thereby accurately generating a control signal.

[0056] When a tapping control device is deployed on upholstered furniture (such as sofas and electric beds), it is subject to environmental noise, vibration, and mechanical interference from scratches, friction, and pressure during furniture use. The semi-enclosed space of the flexible tube has a significantly different acoustic impedance than air, effectively filtering out environmental noise interference. The signals generated by scratching and friction differ from the tapping signal frequency by an order of magnitude, which can also be easily eliminated. Squeezing interference, which is more difficult to eliminate, can also be effectively filtered through the partially enclosed structure of the flexible tube. Specifically, the flexible tube forms a leaky cavity, creating a "band-pass" pneumatic device. The leakage rate and the volume of the cavity determine the sensitive impact frequency range, thereby enabling precise tapping sensing.

[0057] It is understandable that tapping the hose will cause a rapid change in the internal air pressure of hose 1, and the impact signal frequency of the tapping is mainly in the range of 3Hz to 10Hz. By making hose 1 leaky, the influence of lower frequency interference signals can be eliminated. For example, when a person leans against hose 1, hose 1 is subjected to slow but forceful compression. Since hose 1 is not completely sealed, it will gradually leak air until it reaches equilibrium with the external atmospheric pressure, making it less likely to generate strong low-frequency signals that will interfere with the tapping signal and are difficult to filter. Optionally, after being tapped, hose 1 should be able to balance the internal air pressure with the external air pressure within 0.2s to 1s, that is, within 0.2s to 1s after the tapping ends (counting from when the hand leaves the tapping position), the internal air pressure of hose 1 should return to the external atmospheric pressure. The faster the internal air pressure and external air pressure of hose 1 reach equilibrium, the weaker the impact signal generated after tapping is generally. Setting it to balance the internal air pressure and external air pressure within 0.2s to 1s ensures that hose 1 generates an easily identifiable impact signal after being tapped.

[0058] The hose 1 can be made partially sealed in several ways. For example, one end of the hose 1 can be made open, and / or a vent 10 can be provided on the hose 1, and / or the connection between the hose 1 and the microphone 3 can be made with a gap, etc. By controlling the area of ​​the opening and / or the area of ​​the gap, the leakage rate can be changed to obtain different filtering effects (finding the desired sensitivity range). It can be understood that the size of the opening / gap determines the high-pass cutoff frequency.

[0059] In some embodiments, such as Figure 3 As shown, microphone 3 is located at one end of the length of hose 1, while the other end of hose 1 is open (not closed). This allows for gas exchange with the outside environment through the open end when hose 1 deforms, balancing the internal and external air pressures. In this embodiment, hose 1 does not require a separate vent 10, simplifying manufacturing. Optionally, the cross-sectional area at the opening of hose 1 is no greater than 20 mm², ensuring that microphone 3 can reliably generate a sensing signal and maintain sensitivity. Simultaneously, the openings of microphone 3 and hose 1 are located at opposite ends of hose 1, which helps reduce echo reverberation interference and further enhances specificity (interference rejection capability).

[0060] In some embodiments, the microphone 3 is located at one end of the hose 1 along its length, and the other end of the hose 1 along its length is closed, with a passage for gas to enter and exit between the microphone 3 and the hose 1. For example, there is a gap between the microphone 3 and the hose 1 to allow gas to flow out. Figure 4 As shown, microphone 3 is fixed to the end of hose 1 by connecting plug 30. Connecting plug 30 has a through hole 300 to form a passage for gas to flow out. When hose 1 is tapped, the gas mainly flows towards the location of microphone 3, which can generate a larger impact sound wave and improve the sensitivity of microphone 3.

[0061] In some embodiments, such as Figure 5 As shown, both ends of the hose 1 are closed, and the hose body is provided with a vent hole 10 to form a passage for gas to enter and exit. The closure of the ends of the hose 1 can be achieved by the hose 1 itself sealing, or by sealing it with a sealing component. Figure 5 In this configuration, one end of the flexible tube 1 is naturally sealed, while the other end is sealed by mounting a microphone 3. Optionally, the cross-sectional area of ​​a single vent 10 is no greater than 20 mm², so that the microphone 3 can reliably generate a sensing signal and ensure sensitivity.

[0062] Optionally, the microphone 3 is located inside the flexible tube 1, and the flexible tube 1 has a contracting portion 12 that surrounds the microphone 3 or the lead wire 31 of the microphone 3 to fix the microphone 3. Specifically, the microphone 3 can be placed inside the open end of the flexible tube 1 first, and then the end of the flexible tube 1 can be contracted by heat fusion, thereby covering the lead wire 31 of the microphone 3. No additional connecting components are required, the structure is simpler, and the cost is lower.

[0063] In some embodiments, such as Figure 6 As shown, microphones 3 are installed at both ends of the flexible tube 1. When the flexible tube 1 is tapped, both microphones 3 generate induction signals. Furthermore, the microphone 3 farther from the tapping location generates its induction signal later. By analyzing the phase difference between the signals with consistent contours acquired by the two microphones 3, the tapping and the segment in which it occurs can be accurately assessed. This allows for different control functions to be achieved through tapping at different locations. In other words, the control circuit can generate different control signals based at least on the phase difference (or time difference) of the induction signals generated by the two microphones 3, thus diversifying control functions. For example, different control functions can be achieved by tapping different locations. Figure 7 In the illustrated embodiment, the flexible hose 1 is divided into three segments: segment A near the left microphone 3, segment C near the right microphone 3, and segment B between segments A and C. Clearly, when segments A and C are tapped, the difference in the inductive signals generated by the two microphones 3 is greater; when segment B is tapped, the difference in the inductive signals is smaller. Therefore, based on the phase difference of the inductive signals in different segments, three different control signals can be obtained. For example, tapping segment A can drive the electric sofa to deform into a sitting position, tapping segment C can control the electric sofa to deform into a reclining position, tapping segment C can control the electric sofa to stop deforming, and so on. Diverse control functions are achieved using only a single flexible hose 1 and two microphones 3, resulting in a simple structure and lower cost.

[0064] Understandably, hose 1 can be divided into more segments to achieve more diverse control functions.

[0065] Optionally, in some embodiments, the flexible tube 1 has a non-deformable portion (the other portion can be referred to as a deformable portion), which cannot be deformed by being struck. For example, a part of the flexible tube 1 can be made of a rigid material (such as plastic or metal). Alternatively, a rigid component 13 (such as a rigid tube) can be used to cover a portion of the flexible tube 1, making that portion undeformable by being struck. In this way, the time difference between the electrical signals generated by the two microphones 3 can be controlled, improving the accuracy of detection. Figure 8In the illustrated embodiment, a rigid member 13 is provided on the outside of segment B. This segment is designed to be non-deformable, so that only tapping segments A and C can generate sensing signals. Since the time difference between the sensing signals generated by the two microphones 3 when tapping segments A and C is relatively large, more accurate control signals can be generated.

[0066] Figure 8 and Figure 9 In the illustrated embodiment, the flexible tube 1 is covered with a tubular rigid member 13. In other embodiments, the rigid member 13 may also be a semi-enclosed structure or other shapes.

[0067] It is understood that microphone 3 does not necessarily have to be located at the end of the flexible tube 1; it can also be located on the side wall of the flexible tube 1. When the flexible tube 1 has two microphones 3, the two microphones 3 are spaced apart along the length of the flexible tube 1 to facilitate the generation of a phase difference. Both microphones 3 can be located on the side wall of the flexible tube 1, or one can be located at the end of the flexible tube 1 and the other on the side wall of the flexible tube 1. When microphone 3 is located at the end of the flexible tube 1, and its axis is aligned with or parallel to the axis of the flexible tube 1, the induction signal can be generated more reliably, and installation is more convenient.

[0068] It is understandable that when the flexible tube 1 is equipped with only one microphone 3 (e.g., only one end of the tube), the position of the tube 1 being struck can be determined based on the sensing signal of a single microphone 3, thereby generating different control signals. This is because striking the tube 1 at different positions will result in signals with different frequency domain characteristics at the end of the microphone 3, and the corresponding control signal can be calculated based on the frequency domain characteristics of the sensing signal from the microphone 3. Calculating the position of signal generation (striking position) using a single microphone 3 can be achieved using existing technology, but it requires a sophisticated algorithm. It is also understandable that when the flexible tube 1 is equipped with a single microphone 3, a rigid component 13 can be added to increase the spacing between the deformable parts that can be struck, thereby increasing the signal differentiation.

[0069] The flexible hose 1 can be arranged in a straight line or in a curved manner. As mentioned above, the inherent characteristics of the flexible hose 1 allow it to be easily bent, and thus arranged in a folded shape (such as an S-shape) or a spiral shape, etc., in some embodiments, such as... Figure 10As shown, the flexible tube 1 is bent and includes at least two opposing portions 14 (five in the figure). Optionally, the flexible tube 1 is configured such that at least two opposing portions can be simultaneously tapped with one hand. This allows multiple portions of the flexible tube 1 to deform with a single tap, significantly increasing the intensity of the generated sound waves and thus improving sensitivity. Clearly, by controlling the spacing L between the opposing portions of the flexible tube 1 (e.g., controlling it to be less than the width of a palm or a finger), it is possible to ensure that at least two opposing portions can be simultaneously tapped with one hand.

[0070] It is understandable that, through appropriate structural design, the beneficial effects of improved sensitivity and diverse control functions can coexist. For example, one or more sections of the hose 1 can be made curved to improve the sensitivity when the curved section is being struck. Figure 11 In the illustrated embodiment, segments A and C of the flexible hose 1 are configured to be curved. When segment A or segment C is tapped, multiple parts of that segment can deform, thereby increasing sensitivity. For example, Figure 12 In the illustrated embodiment, segments A, B, and C of the flexible hose 1 are configured to be curved. When any one of segments A, B, or C is tapped, multiple parts of that segment can deform, thereby improving sensitivity. Clearly, the time difference between the generation of sensing signals by the two microphones 3 differs when segments A, B, and C are tapped; therefore, the tapping position can be determined, and a corresponding control signal can be generated. For ease of description, the entire assembly of the opposing portions 14 within the same tapping area of ​​the flexible hose 1 is referred to as the meandering portion. Figure 11 In the middle, sections A and C form two independent winding parts. Figure 12 In the middle, segments A, B and C constitute three independent meandering parts, each of which corresponds to the same slapping area, and the control signals generated when slapping in the same slapping area are the same.

[0071] Obviously, the sensitivity of the tapping control device can be controlled by controlling the length of the hose 1 that is tapped in a single tap.

[0072] It is understood that although in the illustrated embodiment, the portion 14 of the hose 1 is parallel to each other and is straight, it can also be curved, for example, a section of the hose 1 can be made into a spiral shape.

[0073] In some embodiments, the tapping control device further includes a hose fixing assembly 2, which allows the hose 1 to be pre-fixed in a preset shape. The hose fixing assembly 2 includes a base plate 20 and a limiting member 21 connected to the base plate 20, forming a space between the limiting member 21 and the base plate 20 for the hose 1 to pass through. Thus, multiple limiting members 21 can be pre-set on the base plate 20, and the hose 1 can be threaded through the limiting members 21 in a preset manner to maintain the desired shape. The base plate 20 also makes it easier to connect the tapping control device to furniture.

[0074] Optionally, the limiting member 21 can be made of a flexible material, such as cloth or elastic band, so that even if it is hit at the position of the limiting member 21, the hose 1 can be pressed down to generate a control signal, which improves reliability.

[0075] The hose fixing assembly 2 may include multiple (at least two) base plates 20, each base plate 20 having a limiting member 21. Each base plate 20 can fix a portion of the hose 1. For example, the hose 1 may include multiple bends, and the bends of the hose 1 are fixed to the base plate 20. The number of bends fixed on each base plate 20 may be one or more. Figure 14 As shown, the hose fixing assembly 2 includes two base plates 20, each base plate 20 fixing a meandering portion of a hose 1. The portion of the hose 1 outside the two base plates 20 is a connecting portion 22, which connects the meandering portions. This connecting portion 22 allows the relative position of the two base plates 20 to be adjusted according to the actual installation situation, making installation more convenient.

[0076] The flexible tube 1 can be a round tube (with a circular outer contour), a square tube (with a rectangular outer contour), or a tube of other shapes. In some embodiments, such as Figure 15 As shown, in order to reduce the thickness of the hose 1, the cross-section of the hose 1 is set to be flat (e.g., elliptical), which can reduce the installation space (mainly the space in the depth direction) when installed in furniture. Optionally, the thickness B of the internal space of the portion of the hose 1 used for being patted in the patting direction is not less than 2mm.

[0077] Optionally, the material of the hose 1 is silicone, rubber, PVC, acrylate or PET, and the wall thickness is 0.1mm to 3.0mm.

[0078] Understandably, the tapping control device is designed to recognize hand movements, and the specific control commands it generates can be diverse, such as controlling music playback, heating, or furniture deformation. Optionally, the tapping control device can be used to control furniture deformation, allowing the furniture to switch between different shapes by tapping the flexible tube, making it more elegant and convenient to use.

[0079] It is understandable that the tapping control device may include an independent control circuit, which receives the sensing signal from the microphone 3 and calculates the control signal (for example, the control circuit of the tapping control device is electrically connected to the control circuit of the furniture to control the furniture). The tapping control device may also use the control circuit of the furniture, directly connecting the microphone 3 to the control circuit of the furniture, and calculating the control signal through the control circuit of the furniture. In this case, the tapping control device can also be considered to include a control circuit.

[0080] Some embodiments of the present invention provide an electric furniture unit that includes a tapping control device as described above, and performs corresponding functions under the control of the tapping control device. Electric furniture may be, for example, an electric sofa or an electric bed.

[0081] In some embodiments, the electric furniture includes a flexible covering exposed to the outside, such as a fabric covering the outside. A tapping control device is located within the flexible covering. As described above, even if the inner volume of the hose 1 decreases due to compression within the flexible covering, it will not affect the air pressure change generated by the hose 1 after being tapped, thereby achieving reliable control.

[0082] In some embodiments, the flexible hose 1 is disposed on the side of the electric furniture, which can facilitate tapping while reducing the possibility of accidental activation. For example, the flexible hose 1 can be disposed on the side of an electric sofa, or on the side of a deformable mattress of an electric bed, etc. Figure 16 In the illustrated embodiment, the hose 1 is disposed on one side of the electric sofa. Figure 16 The electric sofa includes a backrest 50, a left armrest 51, a right armrest 52, and a base 53. Figure 19 In the illustrated embodiment, the hose 1 is disposed on one side of the deformable mattress.

[0083] In some embodiments, the hose 1 is strip-shaped and extends to multiple sides of the electric furniture simultaneously. Figure 17 The approximate location of hose 1 is shown by dashed lines. Hose 1 is located on the left, front, and right sides of the electric sofa. The transformation of the electric sofa can be controlled from the left, right, and front sides, making it more convenient to use.

[0084] In some embodiments, the hose 1 is generally annular and is arranged around the electric furniture, with its two ends adjacent to each other. Figure 18 In the diagram, the approximate location of the hose 1 is shown by a dotted line. The hose 1 is located on the left, front, right, and rear sides of the electric sofa. It can be controlled by tapping the hose 1 from almost any position, making it more convenient to use.

[0085] Optionally, a tapping control device is used to control the deformation of electric furniture. In addition to achieving different control functions through different tapping positions, the corresponding control signal can also be determined by parameters such as different tapping times and tapping frequencies. For example, a single tap can be set to drive the electric furniture to deform in one direction, two consecutive taps can be set to deform in another direction, and multiple consecutive taps can be set to stop the electric furniture from deforming, and so on.

[0086] It should be noted that, in the absence of conflict, the various embodiments described herein can be combined with each other to obtain more implementation schemes.

[0087] The above are merely specific embodiments of the present invention, and any improvements made based on the concept of the present invention shall be considered within the scope of protection of the present invention.
