Description

Technical Field

[0001] The invention relates to the technical field of smart sofas, in particular to a multifunctional smart sofa. Background Art

[0002] With the rapid development of society, smart furniture has also quickly become popular in people's lives. Smart furniture is based on modern fashion furniture, and cleverly integrates combined intelligence, electronic intelligence, mechanical intelligence, and Internet of Things intelligence into furniture products, making furniture intelligent and fashionable, and making home life more convenient and comfortable. Among them, smart sofas are part of smart furniture, which further improve people's comfort when sitting or lying down.

[0003] In the prior art, smart sofas are usually equipped with an adjustable backrest, a temperature control system and a ventilation system. When people sit or lie on the sofa, the skin of the human body can be kept dry and ventilated. The temperature control system controls the temperature of the sofa surface so that the sofa can maintain the comfort of people at different use temperatures. For example, patent number CN202322633758.6 is a sofa with a ventilation structure, which includes a leather sofa body and a ventilation cushion placed in the middle of the leather sofa body: the ventilation cushion includes a high-density sponge, a horizontal air guide duct assembly arranged horizontally in the front section of the high-density sponge cavity, and a vertical air guide duct assembly arranged vertically in the rear section of the high-density sponge cavity;

[0004] In order to maintain the ventilation effect of the sofa surface, an air duct should be set inside the sofa, and an air outlet connected to the air duct should be set on the sofa surface. Air should be blown out from the open air outlet to ensure that the water vapor emitted by the body at a relatively hot temperature can be quickly taken away, and the ventilation and comfort between the human skin and the sofa surface can be guaranteed. However, the air outlet of this setting method is directly exposed to the sofa surface. When a part of a person's body contacts the sofa surface, the surface of the human body will fit with the sofa surface under the influence of gravity, which will block the air outlet of this part, increase the resistance when the air is discharged from this part, reduce the air discharge volume of this part, and make most of the air flow out of the air outlet that has never contacted the body part. In this way, the air flow cannot take out the hot air emitted by the human body surface, and cannot keep the dryness and ventilation of the human body when it contacts the sofa surface, affecting the comfort of the sofa. In addition, the open air outlet directly exposed to the sofa surface will cause dust and other foreign matter to fall into the air outlet, resulting in blockage of the air holes in this part, affecting the ventilation of this part and the comfort of the sofa.

[0005] In view of the above situation, in order to overcome the above technical problems, the present invention designs a multifunctional smart sofa. Summary of the invention

[0006] The purpose of the present invention is to provide a multifunctional intelligent sofa, in which open air vents are directly exposed on the surface of the sofa. When people's body parts come into contact with the sofa surface, the human body surface will fit with the sofa surface under the influence of gravity, thus blocking the air vents in this part, causing airflow to flow out from the air vents in other parts. The outflowing airflow cannot come into contact with the human body to take away the heat emitted by the human body, and the pressing plate moves downward under the influence of gravity, so that the sofa cover located on the outer side of the pressing plate sinks to form grooves covering several groups of air outlets, thereby preventing the human body from directly fitting into the air outlets.

[0007] To achieve the above object, the present invention provides the following technical solutions:

The pressure plate moves downward under the influence of gravity, so that the sofa cover located on the outside of the pressure plate sinks to form grooves covering several groups of air outlets. When gravity is applied to the human body, the pressure plate moves downward under the influence of gravity, and then moves toward the lower part of the sofa cover, so that the outer periphery of the pressure plate pulls the sofa cover downward, so that the sofa cover located on the outside of the pressure plate sinks to form grooves covering the air outlets, thereby avoiding direct contact between the human body and the air outlet. The sofa cover is arranged on the outside of the seat cushion, the electrically adjustable leg support and the electrically adjustable back support.

[0009] Preferably, the lower end of the pressing plate extends to the lower surface of the sofa cover, and a boss is integrally formed on the outer wall of the lower end of the pressing plate.

[0014] Preferably, the filling assembly includes a fan-shaped airbag, which is arranged inside a storage cavity, one side surface of the fan-shaped airbag is fixedly installed inside the storage cavity, the other side surface of the fan-shaped airbag is fixedly connected to an electrically adjustable leg support, the fan-shaped airbag is provided with a plurality of inner bending portions and a plurality of outer bending portions, the interior of the fan-shaped airbag is connected to an inflation tube, and when working, the fan-shaped airbag uses the plurality of inner bending portions and the plurality of outer bending portions as bending points, thereby realizing contraction, folding or expansion.

[0015] Preferably, a pressure rod is fixedly installed on the inner wall of the fan-shaped airbag at the recessed part of each outer bending part, and a support rod is fixedly connected to the pressure rod. A swivel is fixedly installed on the upper end of the support rod, and a fixed shaft is rotatably installed inside the swivel. Both ends of the fixed shaft are respectively fixedly installed on the inner wall of the fan-shaped airbag. The pressure rod can rotate around the fixed shaft with the swivel as the center to adjust the angle, thereby limiting the position of the outer bending part and preventing the outer bending part from expanding in the outer peripheral direction.

[0016] Preferably, the outer bending portion has an extension end arranged toward the fan-shaped airbag, and the fan-shaped airbag and the outer bending portion are made of rubber material. The rubber fan-shaped airbag and the outer bending portion have sealing properties and elasticity.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The human body applies gravity to the pressing plate, so that the pressing plate moves downward under the influence of gravity, and moves toward the lower part of the sofa cover, so that the outer periphery of the pressing plate pulls the sofa cover downward, so that the sofa cover located on the outer side of the pressing plate sinks to form a groove covering several groups of air outlets, and the airflow component inflates the inside of the air hood so that the airflow flows into the inside of the groove through the air outlet. When the groove is formed, it can prevent the human body surface from directly contacting the air outlet, resulting in the air outlet at this part being unable to exhaust outward, and the groove can form a gas channel surrounding the pressing plate, so that the gas can be evenly diffused to the periphery through the surrounding gas channel, thereby increasing the gas flow area and thus improving the ventilation performance of the sofa.

[0020] 2. The downward movement of the pressure plate will drive the boss and separate it from the lower surface of the sofa cover, so that the air outlet in contact with the human body is connected with the inside of the air hood, and the boss not in contact with the human body is still in contact with the lower surface of the sofa cover, blocking the connection port and the air outlet, and can block the air outlet other than the human body contact part, thereby concentrating the airflow, driving the airflow to flow out from the human body contact part, increasing the gas flow in the human body contact part, and improving the air circulation and heat dissipation effect.

[0021] 3. When the airflow is interrupted, the gas pressure passing through the connection port decreases, driving the area between the two straight gaps to inflate, causing the area to rebound, and the two straight gaps return to their initial state, closing the straight gaps and preventing dust and debris from entering the connection port, causing the connection port to be blocked.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1 , Figure 2 and Figure 3 The present invention provides a multifunctional smart sofa, and the technical solution is as follows:

[0033] A multifunctional intelligent sofa comprises a sofa base 1, a seat cushion 2 is installed on the upper surface of the sofa base 1, a storage cavity 11 is arranged at the front end of the sofa base 1, an electrically adjustable leg support plate 3 is installed inside the storage cavity 11, an electrically adjustable back support plate 4 is installed at the rear end of the sofa base 1, a sofa cover 5 is arranged on the upper surfaces of the seat cushion 2, the electrically adjustable leg support plate 3 and the electrically adjustable back support plate 4, a plurality of pressing plates 6 are fixedly installed on the outer surface of the sofa cover 5, an arc-shaped piece 61 is fixedly installed on the top of the pressing plate 6, the arc-shaped piece 61 is made of flexible material and can improve the comfort of human body contact, the material of the sofa cover 5 is elastic leather, a plurality of groups of air outlets 7 are opened on the outer side of each pressing plate 6 on the upper surface of the sofa cover 5, An air hood 72 is installed on the lower surface of the hair cover 5, and the internal space of the air hood 72 covers several groups of air outlets 7 on the periphery of the pressing plate 6. In this way, when the air inside the air hood 72 is lifted, the air outlets 7 covered inside the air hood 72 can be driven to perform exhaust work. The air hood 72 is sleeved on the outside of the pressing plate 6, and the air hood 72 is connected to the air flow component 8. When in use, the human body applies gravity to make the pressing plate 6 move downward under the influence of gravity, so that the pressing plate 6 moves toward the lower part of the sofa cover 5, so that the outer periphery of the pressing plate 6 pulls the part of the sofa cover 5 downward, so that the part of the sofa cover 5 located on the outer side of the pressing plate 6 sinks to form a groove 51 covering several groups of air outlets 7, and the air flow component 8 inflates the inside of the air hood 72, so that the airflow flows into the inside of the groove 51 through the air outlet 7.

[0034] As an embodiment of the present invention, refer to Figure 3 , Figure 4 and Figure 5 The lower end of the pressing plate 6 extends to the lower surface of the sofa cover 5, and a boss 62 is integrally formed on the outer wall of the lower end of the pressing plate 6. The upper surface of the boss 62 is in contact with the lower surface of the sofa cover 5, and the boss 62 covers several groups of air outlets 7. In this way, when the boss 62 is in contact with the lower surface of the sofa cover 5, the air outlet 7 can be blocked from flowing air outward.

[0035] As an embodiment of the present invention, refer to Figure 3 , Figure 4 and Figure 5 Each group of air outlets 7 is composed of two straight gaps. A connecting port 71 is provided on the lower surface of the sofa cover 5 between the two straight gaps. The connecting port 71 is provided so that the thickness of the portion between the two straight gaps is lower than that of other portions. When affected by air pressure, this portion is more likely to expand and deform, thereby opening the straight gap. The interior of the connecting port 71 is connected to the straight gap. The material of the portion between the two straight gaps is elastic material. The connecting port 71 is located on the inner side of the air cover 72.

[0036] As an embodiment of the present invention, refer to Figure 6The pressing plate 6 is set as a polygon, and the two straight gaps of each group of air outlets 7 are respectively set on both sides of the corners of the pressing plate 6. The pressing plate 6 is set as a polygon. When the pressing plate 6 moves downward to pull the sofa cover 5, the corner of the pressing plate 6 will increase in length, and the pulling force will be concentrated on the corner, so that the pulled sofa cover 5 forms a pressing groove that expands outward and is connected to the groove 51. The pressing groove can improve the flow path of the airflow, so that the gas can diffuse outward faster, thereby further improving the heat dissipation efficiency.

[0037] As an embodiment of the present invention, refer to Figure 7 The airflow component 8 includes an air channel 82 installed on the sofa base 1, an air inlet pipe 81 is installed at the top of the gas channel 82, and the end of the air inlet pipe 81 is connected to the air cover 72. An air heater 84 is installed inside the gas channel 82, and a fan 86 is connected to the bottom of the gas channel 82 through a connecting pipe 85. A connecting end 83 for connecting to the air outlet of an air conditioner is installed outside the gas channel 82. When in use, the air heater 84 can heat the air flow inside the gas channel 82 to increase the air flow temperature, so that the hot air diffuses to the periphery through the groove 51, thereby increasing the heating rate of the sofa surface, thereby improving the comfort of human body use in low temperature conditions, and the connecting end 83 can be connected to the air outlet of the air conditioner, so that it can cooperate with the air conditioner and adjust the temperature of the sofa surface with the help of the temperature of the air conditioner, thereby improving the comfort of the sofa in different seasons.

[0038] As an embodiment of the present invention, refer to Figure 7 and Figure 8 A filling component 9 is installed at the inner angle between the storage cavity 11 and the electrically adjustable leg support plate 3, the sofa cover 5 is provided with an inflatable cavity 10, the inflatable cavity 10 is arranged at the connection between the seat cushion 2 and the electrically adjustable back support plate 4, an inflatable tube 101 connected to the filling component 9 is installed inside the inflatable cavity 10, the filling component 9 includes a fan-shaped airbag 91, the fan-shaped airbag 91 is arranged inside the storage cavity 11, one side surface of the fan-shaped airbag 91 is fixedly installed inside the storage cavity 11, the other side surface of the fan-shaped airbag 91 is fixedly connected to the electrically adjustable leg support plate 3, and the fan-shaped airbag 91 is provided with some The inner bending portion 92 and the outer bending portions 93 are connected to the fan-shaped airbag 91, and the fan-shaped airbag 91 can be stretched or squeezed when the electric leg support plate 3 is adjusted, so that the fan-shaped airbag 91 is in an inhalation or deflation state. In the inhalation state, one side of the fan-shaped airbag 91 will be affected by the tension generated by the movement of the electric adjustable back support plate 4, and then expand outward. In this way, during the expansion of the fan-shaped airbag 91, negative pressure will be generated inside the inflation tube 101, and the air inside the inflation cavity 10 will be sucked into the fan-shaped airbag 91;

[0039] In the blowing state, the electrically adjustable leg support plate 3 squeezes the fan-shaped airbag 91, so that the air inside the fan-shaped airbag 91 enters the inflation cavity 10 through the inflation tube 101, so that the air inside the inflation cavity 10 drives the sofa cover 5 to expand, so that this part forms a waist cushion.

[0040] As an embodiment of the present invention, refer to Figure 7 and Figure 8 A pressure rod 94 is fixedly installed on the inner wall of the fan-shaped airbag 91 at the recessed part of each outer bending part 93, and a support rod 95 is fixedly connected to the pressure rod 94. A swivel 96 is fixedly installed on the upper end of the support rod 95. A fixed shaft 97 is rotatably installed inside the swivel 96. Both ends of the fixed shaft 97 are respectively fixedly installed on the inner wall of the fan-shaped airbag 91. When the fan-shaped airbag 91 moves, the pressure rod 94 will rotate with the swivel 96 as the center of the circle to support the expansion and contraction of the fan-shaped airbag 91, and rotate to adjust the angle as the fan-shaped airbag 91 moves, and support the outer bending part 93.

[0041] As an embodiment of the present invention, refer to Figure 7 and Figure 8 The outer bending portion 93 has an extension end arranged toward the fan-shaped airbag 91. The fan-shaped airbag 91 and the outer bending portion 93 are made of rubber material. When the fan-shaped airbag 91 is deployed, the extension end of the outer bending portion 93 contacts the ground, and can clean out impurities accumulated for a long time in the part during the deployment process. At the same time, since the length of the extension end is longer than the gap between the outer bending portion 93 and the ground, the extension end will bend during the cleaning process, and will gradually separate from the ground during the movement of the extension end. At this time, the rebound force generated by the bending of the extension end pushes A thrust is applied to the cleaned impurities to push the impurities outward to prevent the impurities from being brought into the original position when the extended end is reset. A limit rod 12 is fixedly installed on the inner wall of the storage chamber 11. The limit rod 12 is located at the bottom of the storage chamber 11. The waistline of the extended end of the outer bending portion 93 is in the same horizontal plane as the limit rod 12. When the extended end moves and resets, the limit rod 12 contacts the waistline of the extended end to limit the extended end, so that when the extended end reciprocates through the limit rod 12, the movable end of the extended end is always facing the limit rod 12, thereby completing the cleaning work reciprocatingly.

[0042] Working principle:

[0043] When the surface of the human body contacts the surface of the arc-shaped member 61, weight is applied to the pressing plate 6 through the arc-shaped member 61 in contact with the human body, so that the pressing plate 6 moves toward the lower part of the sofa cover 5, and the outer periphery of the pressing plate 6 pulls the part of the sofa cover 5 downward, so that the part of the sofa cover 5 located outside the pressing plate 6 sinks to form a groove 51 covering several groups of air outlets 7, thereby preventing the air outlets 7 from being blocked when the human body sits on the sofa cover 5.

[0044] When the pressing plate 6 moves downward, the lower end of the pressing plate 6 will drive the boss 62 to move downward, so that the boss 62 is separated from the lower surface of the sofa cover 5, so that the air outlet 7 in contact with the human body can be connected with the inside of the air hood 72 (while the boss 62 in the part not in contact with the human body is not affected by the pressure generated by gravity, the boss 62 in this part is still in contact with the lower surface of the sofa cover 5, blocking the connection port 71 and the air outlet 7, so as to prevent the airflow from flowing out from this part, and then concentrate the airflow, so that the airflow flows out from the part in contact with the human body, thereby improving the gas flowability in this part).

[0045] When the fan 86 is working, the external airflow can be guided to the connecting pipe 85 and the inside of the gas channel 82, and flow into the inside of the gas cover 72 through the air inlet pipe 81 at the top of the gas channel 82, so that the gas enters the connecting port 71 covered by the gas cover 72, thereby increasing the gas pressure inside the connecting port 71, inflating the area between the two straight gaps, thereby expanding the openings of the two straight gaps, and allowing the gas to flow out;

[0046] When the airflow is interrupted, the gas pressure passing through the connection port 71 decreases, driving the area between the two straight gaps to inflate and expand, causing the area to rebound, and the two straight gaps to return to their initial state, preventing the two straight gaps of the connection port 71 from opening in a non-ventilated state, and closing the straight gaps.

[0047] The sofa has two states. The first state is the sofa mode. In this mode, the electrically adjustable leg rest 3 rotates and is retracted into the storage cavity 11. At the same time, the electrically adjustable leg rest 3 squeezes the fan-shaped airbag 91, so that the air inside the fan-shaped airbag 91 enters the interior of the inflation cavity 10 through the inflation tube 101, so that the internal air of the inflation cavity 10 drives the sofa cover 5 to expand, so that a waist cushion is formed in this part, which can improve the comfort of people's waist. At the same time, the cushion is set to be inflatable and located inside the sofa cover 5, which can avoid the problem of displacement of the waist cushion due to squeezing by the human body during use.

[0048] The second state is the lying mode. In this mode, the electrically adjustable leg rest 3 rotates from the storage cavity 11 to the outside and is adjusted to a horizontal state with the seat cushion 2. The electrically adjustable back support 4 rotates from an inclined state to a horizontal state with the seat cushion 2. During the adjustment of the electrically adjustable leg rest 3, one side of the fan-shaped air bag 91 will be expanded outward by the pulling force generated by the movement of the electrically adjustable back support 4. In this way, during the expansion of the fan-shaped air bag 91, negative pressure will be generated inside the inflation tube 101, and then the air inside the inflation cavity 10 will be sucked into the fan-shaped air bag 91, causing the lumbar cushion to disappear. This avoids the situation in which the gas inside the inflation cavity 10 supports the human waist in the lying flat mode, completes automatic adjustment, and improves the comfort in the lying flat state.

[0049] When the fan-shaped airbag 91 is unfolded, the extended end of the outer bending part 93 is in contact with the ground, and impurities accumulated in this part for a long time can be cleaned out during the unfolding process. At the same time, the fan-shaped airbag 91 can fill the area between the electrically adjustable leg rest 3 and the sofa base 1 to prevent foreign objects and pets from entering this area when the electrically adjustable leg rest 3 is in a horizontal state, and to prevent the moving path of the electrically adjustable leg rest 3 from being affected and becoming unable to adjust when the electrically adjustable leg rest 3 is in an adjusted state.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
