[0052] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0053] In the description of the present utility model, it is to be understood that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centrally arranged component at the same time.

[0054] In addition, terms such as "long", "short", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention. They do not indicate or imply that the device or component referred to must have this specific direction or operate with a specific direction structure, and should not be understood as a limitation of the present invention.

[0055] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0056] The utility model provides a backrest assembly and furniture, which are suitable for application scenarios of providing support for the back of a user, and can effectively solve the problem that the user cannot adjust the support position according to his own needs, resulting in a poor user experience.

[0057] This embodiment provides a piece of furniture, including a backrest assembly and a frame body installed and fixed in front of the backrest assembly. For example, when the furniture is a bed frame, the frame body is a bed frame, and when the furniture is a sofa, the frame body is a seat frame. A user can sit on the frame body and then lean back on the backrest assembly.

[0058] See also Figure 1 The backrest assembly includes a backrest base frame 1, a support detection plate 2 installed on the backrest base frame 1, a sliding support member 3 installed on the support detection plate 2 for sliding up and down movement, and a control actuator 4 electrically connected to the support detection plate 2.

[0059] The support detection plate 2 is used to detect the support condition of the sliding support member 3 on the human body.

[0060] The control execution mechanism 4 is used to receive the detection result of the support detection plate 2 and drive the sliding support member 3 to slide relative to the support detection plate 2, so that the sliding support member 3 provides support for the human body.

[0061] The backrest assembly and furniture provided in this embodiment use a support detection plate 2 to detect the support condition of the sliding support member 3 for the human body. After the control actuator 4 receives the detection result of the support detection plate 2, it drives the sliding support member 3 to slide relative to the support detection plate 2, so that the position of the sliding support member 3 is adapted to the human body posture, thereby providing sufficient support for the back of the human body.

[0062] Therefore, the backrest assembly and furniture provided by the present invention can effectively solve the problem that users cannot adjust the support position according to their own needs, resulting in a poor user experience.

[0063] In this embodiment, the support detection board 2 mainly detects the posture of the human body through pressure parameters. Specifically, the support detection board 2 includes a base plate body 201 and a plurality of pressure sensors 202 installed on the base plate body 201 near the side of the sliding support member 3; wherein each of the pressure sensors 202 is electrically connected to the control actuator 4.

[0064] When the user's back rests on the sliding support 3, the user's back will apply pressure to the pressure sensor 202 on the bottom plate body 201 through the sliding support 3. The pressure values ​​detected by the pressure sensors 202 can be used to determine whether the sliding support 3 has pressed against the user's back. If the pressure value is small, it means that the user's back is suspended in the air and the sliding support 3 has not pressed against the user's back; if the pressure value is large, it means that the sliding support 3 has pressed against the user's back, and the larger the pressure value, the greater the support force of the sliding support 3 on the user's back. Therefore, when the pressure value reaches the preset value, it can be considered that the sliding support 3 just provides a relatively comfortable support for the user's back.

[0065] In some other embodiments, the support detection board 2 can also detect the human posture through distance parameters. For example, a number of distance sensors or camera modules are set to detect the distance between the back and the sliding support 3. When the distance between the back and the sliding support 3 is too large, it is considered that adjustment is required. When the distance between the back and the sliding support 3 reaches a preset value, the adjustment can be stopped.

[0066] In this embodiment, the bottom plate body 201 is a hollow airbag structure. The bottom plate body 201 of the airbag structure has a large deformation performance and can be adaptively deformed to a certain extent according to the user's back-resting posture to ensure that the sliding support member 3 can face the user's back as much as possible.

[0067] In some other embodiments, the bottom plate body 201 may also be a solid plate structure, but the present invention does not limit this.

[0068] Optionally, a plurality of mounting holes 2011 are arranged at intervals from top to bottom on both sides of the base plate body 201. The backrest bottom frame 1 is provided with bolt holes, and the mounting height of the base plate body 201 can be adjusted by aligning the bolt holes with different mounting holes 2011, thereby changing the limit position of the sliding support member 3.

[0069] See also Figure 2 to Figure 4 In this embodiment, a longitudinal slide groove 2012 is provided on one side of the support detection plate 2 close to the sliding support member 3. The control actuator 4 includes a first end magnetic attraction member 401a, a second end magnetic attraction member 401b, a magnetized member 402 and a control device 403.

[0070] The first end magnetic member 401a is fixed at the top of the longitudinal slide groove 2012; the second end magnetic member 401b is fixed at the bottom of the longitudinal slide groove 2012; the magnetized member 402 is fixed on the sliding support member 3, and is slidably connected to the support detection plate 2 along the longitudinal slide groove 2012. The control device 403 is electrically connected to the support detection plate 2, the first end magnetic member 401a, and the second end magnetic member 401b, respectively, and is used to supply power to the first end magnetic member 401a and the second end magnetic member 401b, so that the magnetized member 402 is acted upon by the magnetic force of the first end magnetic member 401a and the second end magnetic member 401b, and drives the sliding support member 3 to slide up and down relative to the support detection plate 2.

[0071] For example, the first end magnetic attraction member 401a provides attraction to the magnetized member 402, and the second end magnetic attraction member 401b provides repulsion to the magnetized member 402, so as to overcome the gravity of the sliding support member 3, so that the sliding support member 3 slides upward and pushes the back of the human body. When the sliding support member 3 needs to slide upward or the support strength needs to be increased, the current is controlled to increase the attraction and / or repulsion; when the sliding support member 3 needs to slide downward or the support strength needs to be reduced, the current is controlled to reduce the attraction and / or repulsion.

[0072] In this embodiment, in order to position the sliding support member 3 on the support detection plate 2 and prevent the sliding support member 3 from detaching from the support detection plate 2 forward along the thickness direction of the support detection plate 2, an intermediate magnetic member 401c may be provided between the first end magnetic member 401a and the second end magnetic member 401b, and the intermediate magnetic member 401c is magnetically attracted to the magnetized member 402, so that the sliding support member 3 is closely attached to the support detection plate 2. Of course, a guide rail slider assembly may also be provided, so that the sliding support member 3 is slidably connected to the support detection plate 2 through the guide rail slider assembly; wherein the sliding direction of the guide rail slider assembly is parallel to the length direction of the longitudinal slide groove 2012.

[0073] Of course, in some other embodiments, the sliding support member 3 can also be controlled by the motor 406 screw rod 405 assembly to slide up and down. Figure 5The control actuator 4 includes a slider 404, a screw rod 405, a motor 406, and a control device 403. The slider 404 is fixed to the back of the sliding support 3 and is connected to the support detection plate 2 in an upward and downward sliding manner; the screw rod 405 is rotatably mounted on the support detection plate 2 and is threadedly connected to the slider 404; the driving end of the motor 406 is transmission-connected to the screw rod 405; the control device 403 is electrically connected to the support detection plate 2 and the motor 406, respectively, and is used to supply power to the motor 406, so that the slider 404 is driven by the screw rod 405 to drive the sliding support 3 to slide up and down relative to the support detection plate 2.

[0074] In this embodiment, the back surface size of the lower support portion 302 is larger than the back surface size of the upper support portion 301 , and the surface of the upper support portion 301 close to the human body is an arc-shaped surface 3011 .

[0075] In this embodiment, the sliding support member 3 is a sponge structure or an airbag structure. Further, the sliding support member 3 includes an upper support portion 301 and a lower support portion 302 located on the side of the upper support portion 301 close to the support detection plate 2. The back of the lower support portion 302 is relatively large to facilitate the installation of the magnetic receiving member 402; the arc surface 3011 is conducive to entering the suspended space under the user's back to provide back support to the user.

[0076] In some other embodiments, the upper support part 301 is a sponge structure or an airbag structure, the lower support part 302 is a solid plate, and the magnetic component 402 is installed on the back of the lower support part 302; or, the upper support part 301 and the lower support part 302 are both sponge structures or airbag structures, and a solid plate is set on the back of the lower support part 302, and the magnetic component 402 is installed on the back of the solid plate. It can be understood that the solid plate has a higher structural strength and poorer deformation performance, which is conducive to reducing sliding friction resistance. Installing the magnetic component 402 on the back of the solid plate can improve the sliding smoothness when the sliding support 3 and the support detection plate 2 slide relative to each other.

[0077] Optionally, the control device 403 includes a muffler box 4031 with an exhaust hole, a circuit board located in the muffler box 4031, and a control panel 4032 electrically connected to the circuit board through a wire. By operating the buttons on the control panel 4032, the sliding support member 3 can be inflated or deflated, and / or the upper and lower positions of the sliding support member 3 can be fine-tuned, etc., which is not limited in the present invention.

[0078] In summary, the backrest assembly and furniture provided in this embodiment have the following beneficial effects:

[0079] ① After receiving the detection result of the support detection plate 2, the control actuator 4 drives the sliding support member 3 to slide relative to the support detection plate 2, so that the position of the sliding support member 3 is adapted to the human body posture, thereby providing sufficient support to the back of the human body;

[0080] ② The bottom plate body 201 is a hollow airbag structure with a large deformation performance, and can be adaptively deformed to a certain extent according to the user's back-leaning posture, so as to ensure that the sliding support member 3 can face the user's back as much as possible;

[0081] ③ The sliding support member 3 is driven to slide by magnetic force, without the need to use noisy driving components such as cylinders, which is conducive to reducing the noise when the sliding support member 3 moves up and down, thereby improving the user experience.

[0082] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
