Description

Technical Field

[0001] The present invention belongs to the technical field of smart home equipment, and in particular relates to a linkage smart bed. Background Art

[0002] With the improvement of people's living standards and their concern for healthy living, the demand for smart furniture is gradually increasing. Among many smart furniture, smart beds are popular because they can provide personalized comfort experience. Existing smart beds usually have certain adjustment functions, such as mattress height adjustment, backrest angle change, etc., but there are still some shortcomings in structural design, function realization and user experience.

[0003] Most traditional smart beds use a single electric adjustment system, which lacks flexibility and diversity and cannot meet the personalized requirements of users for different sleeping positions and rest needs. In addition, existing technologies often use rigid connections for power transmission and component connections, which not only increases mechanical wear, but may also shorten the service life of the motor. Moreover, adjustments for different parts often require multiple independent motors and control systems, which increases the overall complexity and cost.

[0004] At the head of the bed, most existing smart beds use a simple backrest adjustment method, lacking a comprehensive adjustment design for the neck and back, and cannot effectively adapt to the needs of users in different states. At the same time, the functional design of the bedside table is relatively simple, lacking linkage with the bed, and cannot provide a better user experience.

[0005] In addition, existing smart beds also have limitations in terms of transportation and storage. Most smart beds are bulky and cannot be effectively folded and space-saving, resulting in inconvenience during relocation and storage. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a linkage intelligent bed that solves the above-mentioned technical problems existing in the prior art.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A linkage intelligent bed comprises a bed head body and a bed body, wherein the bed head body is located at the front end portion where the bed body is located.

[0009] The bed body includes a bed frame and a mattress, and a back bed board movable assembly, a waist bed board assembly and a leg bed board movable assembly are arranged on the bed frame, so that the mattress forms an upper cover of the back bed board movable assembly, the waist bed board assembly and the leg bed board movable assembly;

[0010] The lumbar bed board assembly is horizontally fixed to the middle of the upper surface of the bed frame, and the lumbar bed board assembly is lifted to adjust the bulge of the middle of the upper mattress;

[0011] The back bed board movable assembly is horizontally fixed to the front part of the upper surface of the bed frame, and the lifting height of the front part of the upper mattress is adjusted by the deflection of the back bed board movable assembly;

[0012] The leg bed board movable assembly is horizontally fixed to the rear part of the upper surface of the bed frame, and the lifting height adjustment of the upper mattress candidate is formed through the deflection of the leg bed board movable assembly.

[0013] Furthermore, the back bed board movable assembly includes a first motor, a first U-shaped bracket, a first roller member, and a back bed board member; the crossbeam of the first U-shaped bracket is arranged across and has both ends hinged on the bed frame, and the ends of the two groups of legs where the first U-shaped bracket is located are connected to the first roller member;

[0014] The inner side end of the back bed board component is hingedly connected to the waist bed board component, and the other side end faces outwards;

[0015] One end of the first motor is fixed to the end of the bed frame, and the other end is connected to the first U-shaped bracket. The first motor pushes the first U-shaped bracket so that the first U-shaped bracket rotates with the middle cross beam as the axis of rotation. The first roller on the first U-shaped bracket rolls on the bottom of the back bed board and deflects and rotates synchronously.

[0016] Furthermore, the back bed board members are divided into two groups which are parallelly distributed and hinged to each other, and a head motor is arranged at the bottom of the back bed board members, so that the back bed board members located on the outside are deflected by the head motor.

[0017] Furthermore, the leg bed board movable assembly includes a second motor, a second U-shaped bracket, a second roller member, and a leg bed board member; the crossbeam of the second U-shaped bracket is arranged across and has both ends hinged on the bed frame, and the ends of the two groups of legs where the second U-shaped bracket is located are connected to the second roller member;

[0018] The leg bed board member located on the inner side is hingedly connected to the waist bed board assembly, and the leg bed board member located on the outer side extends outward;

[0019] One end of the second motor is fixed to the end of the bed frame, and the other end is connected to the second U-shaped bracket. The second motor pushes the second U-shaped bracket so that the second U-shaped bracket rotates with the middle crossbeam as the rotation axis, and the second roller on the second U-shaped bracket rolls at the bottom of the inner leg bed plate and deflects and rotates synchronously;

[0020] The outer side of the lower part of the leg bed board member located on the outer side is connected to the end of the bed frame through a connecting piece.

[0021] Furthermore, the leg bed board members are divided into two groups which are parallelly distributed and hinged to each other, and a foot motor is arranged at the bottom of the leg bed board members, so that the leg bed board members located on the outside can be deflected by the foot motor.

[0022] Furthermore, the bed frame is located in the middle and is divided into two front-to-back symmetrical groups by a hinge, so that the bed frame can be turned over and folded as a whole.

[0023] Furthermore, the lumbar bed board assembly includes a lumbar bed board component, a lumbar motor and an L-shaped top lumbar component. The lumbar motor is located at the bottom of the lumbar bed board component, and the output end of the lumbar motor forms an output to the L-shaped top lumbar component, so that the L-shaped top lumbar component pushes the middle part of the upper mattress upward.

[0024] Furthermore, the head of the bed includes a bedside table, a backrest motion assembly, and a backrest cushion. The bedside table is embedded with the backrest motion assembly, and the backrest cushion wraps the outside of the backrest motion assembly. The backrest motion assembly forms a multi-angle deflection movement and synchronously drives the movement of the backrest cushion.

[0025] Further, the backrest motion assembly includes a backrest mounting plate, a backrest angle adjustment plate, a hinge, and a third drive motor;

[0026] The rear end surface of the backrest mounting plate is fixed to the inner side of the bedside table, and the front end portion is hinged to the backrest angle adjustment plate through hinges symmetrically arranged on both sides. At the same time, the third drive motor is installed in the middle part of the backrest mounting plate, and the output end of the third drive motor is connected to the transverse connecting rod between the two groups of hinges. Then, the third drive motor drives the hinge connected to the transverse connecting rod to swing, thereby synchronously realizing the deflection of the backrest angle adjustment plate.

[0027] Furthermore, two groups of hinge holes are provided at the lower part where the backrest angle adjustment plate is located, and are connected to the two groups of hinges synchronously. A neck angle adjustment plate is synchronously hinged on the hinge located at the lower end, so that when the hinge is hinged, the backrest angle adjustment plate and the neck angle adjustment plate move relative to each other.

[0028] Furthermore, a massage driving component is arranged between the backrest angle adjustment plate and the neck angle adjustment plate, so that the massage driving component is located at the rear end portion where the backrest cushion is located, and the backrest cushion is synchronously driven to creep through the driving of the massage driving component.

[0029] Furthermore, the inner side of the neck angle adjustment plate and one group of hinged parts is connected by a spring member, so that the deflection angle of the neck angle adjustment plate with respect to the vertical direction is less than 13 degrees.

[0056] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0057] like Figure 1As shown, an embodiment of the present invention provides a linkage intelligent bed, including a headboard body 1 and a bed body 2. The headboard body 1 is located at the front end of the bed body 2. The headboard body 1 can be assembled together or separately and customized according to market demand.

[0058] like Figure 2 As shown, the bed body 2 includes a bed frame 21 and a mattress 22. The bed frame 21 is used as a supporting structure of the bed body to provide stability and bearing capacity. The mattress 22 is placed on the bed frame 21 to provide a comfortable resting experience. A back bed board movable assembly 211, a waist bed board assembly 212 and a leg bed board movable assembly 213 are arranged on the bed frame 21, so that the mattress 22 forms an upper cover of the back bed board movable assembly 211, the waist bed board assembly 212 and the leg bed board movable assembly 213;

[0059] like Fig.10 , Fig.11 As shown, the lumbar bed board assembly 212 is horizontally fixed to the middle of the upper surface of the bed frame 21, and the lumbar bed board assembly 212 is lifted to form a bulge adjustment on the middle of the upper mattress 22, thereby achieving a bulge adjustment effect on the middle of the mattress 22;

[0060] At this time, the lumbar bed board assembly 212 includes a lumbar bed board component 2121, a lumbar motor 2122 and an L-shaped top lumbar component 2123. The lumbar motor 2122 is located at the bottom of the lumbar bed board component 2121, and the output end of the lumbar motor 2122 forms an output to the L-shaped top lumbar component 2123 (that is, at this time, the rear end of the lumbar motor 2122 is fixed on the bracket where the bed frame 21 is located, so its output end can output transmission to the L-shaped top lumbar component 2123), so that the L-shaped top lumbar component 2123 forms an upward push against the middle part of the upper mattress 22. At this time, the L-shaped top lumbar component 2123 presents a horizontal circular tube structure as a whole. Therefore, when driven, it can form a uniform force on the bottom of the mattress 22, ensure the comfort of the middle part of the mattress, and make the middle part bulge.

[0061] like Figure 3-Figure 7 As shown, the back bed board movable component 211 is horizontally fixed on the front part of the upper surface of the bed frame 21, and the lifting height adjustment of the front part of the upper mattress 22 is formed by the deflection of the back bed board movable component 211; the back bed board movable component 211 includes a first motor 2111, a first U-shaped bracket 2112, a first roller member 2113, and a back bed board member 2114; the crossbeam of the first U-shaped bracket 2112 is arranged horizontally and has its two ends hinged on the bed frame 21, and the ends of the two groups of legs of the first U-shaped bracket 2112 are connected to the first roller member 2113, and the synchronous angle change of the upper back bed board member 2114 is achieved by the deflection of the first U-shaped bracket 2112.

[0062] The inner end of the back bed board component 2114 is hingedly connected to the lumbar bed board assembly 212, and the other side end faces outward. When the back bed board component 2114 is driven by the output of the first motor 2111, the back bed board component 2114 only deflects and does not lose connection with the lumbar bed board assembly 212.

[0063] One end of the first motor 2111 is fixed to the end of the bed frame 21, and the other end is connected to the first U-shaped bracket 2112. The first motor 2111 pushes the first U-shaped bracket 2112 to rotate with the middle crossbeam as the center of the rotation axis. The first roller part 2113 on the first U-shaped bracket 2112 rolls on the bottom of the back bed board part 2114 and deflects and rotates synchronously. This lifting method can directly flip the back bed board part 2114 without power, without the need for additional disassembly parts.

[0064] like Figure 8 , Fig. 9 As shown, the back bed plate 2114 can be further improved as needed. The back bed plate 2114 is divided into two groups and arranged in parallel and articulated with each other, so it can be used as two independent drive adjustments. At the same time, a head motor 2115 is arranged at the bottom of the back bed plate 2114. The head motor 2115 generates a deflection motion on the back bed plate 2114 located on the outside. This design method can adjust the back bed plate 2114 after the back bed plate 2114 is deflected as a whole. This non-rigid connection method between the first roller 2113 and the back bed plate 2114 greatly protects the service life of the first motor 2111.

[0065] The lower outer side of the back bed board member 2114 located on the outer side is connected to the end of the bed frame 21 through a connecting piece.

[0066] like Figure 5-7 As shown, the leg board movable assembly 213 is horizontally fixed to the rear portion of the upper surface of the bed frame 21, and the lifting height adjustment of the rear portion of the upper mattress 22 is formed by the deflection of the leg board movable assembly 213.

[0067] At this time, the leg bed board movable assembly 213 includes a second motor 2131, a second U-shaped bracket 2132, a second roller member 2133, and a leg bed board member 2134; the crossbeam of the second U-shaped bracket 2132 is arranged across and has both ends hinged on the bed frame 21, the ends of the two groups of legs where the second U-shaped bracket 2132 is located are connected to the second roller member 2133, one end of the second motor 2131 is fixed to the end of the bed frame 21, and the other end is connected to the second U-shaped bracket 2132, through the second motor 2131 The pushing of the second U-shaped bracket 2132 causes the second U-shaped bracket 2132 to rotate with the middle crossbeam as the axis of rotation. The second roller member 2133 on the second U-shaped bracket 2132 rolls at the bottom of the inner leg bed board member 2134 and deflects and rotates synchronously. Its operating principle is similar to that of the back bed board movable component 211. This working mode adopts a non-rigid connection between the leg bed board member 2134 and the second U-shaped bracket 2132, and therefore will not affect the service life of the second motor 2131.

[0068] The leg board components 2134 are divided into two groups and are hinged to each other, so that the leg board components 2134 located on the inner side are hingedly connected to the waist board assembly 212, and the leg board components 2134 located on the outer side extend outward (the length of the mattress 22 can be appropriately increased and adapted to the length requirements). Therefore, when the overall adjustment of the legs is required, the deflection of the leg board components 2134 located on the inner side can be adjusted. At the same time, a foot motor 2135 is set at the bottom of the leg board components 2134, and the foot motor 2135 generates a deflection movement on the leg board components 2134 located on the outer side.

[0069] like Fig.17 As shown, the bed frame 21 is located in the middle and is divided into two symmetrical groups front and back by hinges, and the bed frame 21 can be flipped and folded as a whole. In this way, when separated from the mattress 22, a bending operation can be formed from the middle, which greatly reduces the overall occupied space and improves transportation efficiency.

[0070] like Fig.12 , Fig.13 As shown, the headboard 1 includes a bedside table 11, a backrest motion component 12, and a backrest cushion 13. The backrest motion component 12 is embedded in the bedside table 11, and the backrest cushion 13 wraps the outer side of the backrest motion component 12. The backrest motion component 12 forms a multi-angle deflection movement and synchronously drives the movement of the backrest cushion 13.

[0071] The backrest motion assembly 12 includes a backrest mounting plate 121, a backrest angle adjustment plate 122, a hinge 123, and a third drive motor 124;

[0072] like Figure 14-16As shown, the rear end face of the backrest mounting plate 121 is fixed to the inner side of the bedside cabinet 11, and the front end thereof is hingedly connected to the backrest angle adjustment plate 122 through hinges 123 symmetrically arranged on both sides, and the third drive motor 124 is installed in the middle of the backrest mounting plate 121, and the output end of the third drive motor 124 is connected to the transverse connecting rod 1231 between the two sets of hinges 123, that is, installed in the middle of the backrest mounting plate 121, and the output end is connected to the transverse connecting rod 1231 to drive the swing of the hinge 123, thereby realizing the adjustment of the backrest angle. Subsequently, the hinge 123 connected to the transverse connecting rod 1231 is driven to swing by the third drive motor 124, thereby realizing the deflection of the backrest angle adjustment plate 122 synchronously.

[0073] Furthermore, two groups of hinge holes are provided at the lower part where the backrest angle adjustment plate 122 is located, and are synchronously connected to the two groups of hinges 123. A neck angle adjustment plate 125 is synchronously hinged on the hinge 123 at the lower end, and the neck angle adjustment plate 125 is fixed at the lower end of the backrest angle adjustment plate 122 and connected to the hinge 123. When the hinge 123 moves, the backrest angle adjustment plate 122 and the neck angle adjustment plate 125 will move relative to each other, thereby achieving the angle adjustment of the neck. When the hinge 123 is hinged and moved, the backrest angle adjustment plate 122 and the neck angle adjustment plate 125 will move relative to each other.

[0074] Of course, as needed, Fig.18 As shown, a massage driving member 126 is arranged between the backrest angle adjustment plate 122 and the neck angle adjustment plate 125, so that the massage driving member 126 is located at the rear end portion where the backrest cushion 13 is located, and the backrest cushion 13 is driven synchronously by the driving of the massage driving member 126. In this driving mode, after adjusting the backrest and neck angles, the massage driving member 126 can be driven independently to meet the comfort requirements. This mode is easy to operate, does not affect the aesthetics of the bed, and has good concealment.

[0075] like Fig.19 , Fig. 20 As shown, a spring member 126 is used to connect the inner side between the neck angle adjustment plate 125 and one of the groups of hinges 123; this anti-pinch structure is set to prevent foreign objects from entering when the head of the bed is folded. When foreign objects enter from the top neck angle adjustment plate 125, the third drive motor 124 pulls back, and the bearing returns to the origin by itself. The neck adjustment plate where the neck angle adjustment plate 125 is located maintains the angle unchanged, and the third drive motor 124 stops running. When the foreign object is taken out, the spring member 126 generates tension to pull the neck adjustment plate where the neck angle adjustment plate 125 is located back to the origin. At this time, the spring member 126 has tension whether it is opened or folded, and there is no failure mode.

[0076] The deflection angle of the neck angle adjustment plate 125 from the vertical direction is less than 13 degrees, that is, the neck adjustment plate can be manually opened up to 13 degrees at most, and the maximum gap is 50mm. Since the bearing is always within the range of the guide groove, when it is manually opened, the bearing will slide from the highest point of the guide groove to the lowest point. At this time, the lowest point of the guide groove plays a limiting role to avoid the angle being pulled too far and the bearing falling off. This anti-pinch function is different from other types of anti-pinch. This anti-pinch function can prevent the bearing from falling off. Whether the neck adjustment plate where the neck angle adjustment plate 125 is located is manually opened or retracted, the bearing is always within the range of the slide track and will not fall off.

[0077] In addition, a control module is built into the inner storage cavity of the bedside table 11 to control the opening and folding of the backrest motion assembly 12: the current control methods include remote control control and mini-program control, in which the mini-program is stored on the server, which can add sleep-aiding audio, ventilation and heating functions to the backrest, and can also add atmosphere lights beside the bed.

[0078] There is a server in the background of the mini program, which can be matched with other smart furniture in the home through ports. With the bedside as the centralized control center, the mini program is used to control the furniture, realizing a control system to control the smart home of the entire family without switching the control system back and forth.

[0079] The controller can establish a connection with the TV through WIFI, and can control the TV through voice. At the same time, according to needs, the controller can establish a connection with the lighting system through WIFI, and can control the switch and brightness adjustment of the indoor lighting system through voice, establish a connection with the curtain through WIFI, and can control the opening and closing of the curtain through voice, establish a connection with the sound system through WIFI, and can control the sound system through voice; establish a connection with the air conditioner through WIFI, and can control the opening and closing, mode, temperature, air volume and other settings of the air conditioner through voice.

[0080] When the entire device is in use, it can be connected wirelessly or wired externally to independently control the motor drivers located on the headboard body 1 and the bed body 2. There is a server in the background of the mini program, which can be matched with other smart furniture in the home through ports. The bedside is used as the control center, and the mini program is used to control the furniture, realizing a control system to control the smart home of the entire family without switching the control system back and forth.

[0081] The controller establishes a connection with the humidifier through WIFI, and controls the humidifier on and off and adjusts the amount of spray through voice. At the same time, the controller is equipped with a humidity sensor. When the humidity reaches the appropriate humidity for the human body (or the set humidity value), the controller will automatically issue a command to turn off the humidifier. When the humidity is less than the set value, the controller will automatically issue a command to turn on the humidifier. You can effectively control the smart home at home while lying in bed.

[0082] At present, the humidifiers on the market do not realize automatic start and stop by detecting humidity. Because the humidifier is small in size and the humidity sensor is too close to the spray nozzle, it is impossible to detect the real humidity in the room. The humidity sensor of this product is placed in the smart bed controller, separated from the spray nozzle, to ensure that the detection data is real and effective.

[0083] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
