Description

Technical Field

[0001] This utility model relates to the field of seating technology, and in particular to a lumbar support and a seat. Background Technology

[0002] Seats typically include lumbar supports to support the user's lower back and improve comfort when seated. However, existing lumbar supports are rigid and difficult to deform, resulting in poor comfort. Meanwhile, existing technologies, such as CN201811495162.1, incorporate pressure sensors in the lumbar supports to detect pressure when the user sits down and adjust the lumbar support to suit the user's posture, thus improving comfort.

[0003] By adding a mesh fabric to the lumbar support, the stiffness of the lumbar support can be reduced and comfort improved. However, since the mesh fabric is separated from the lumbar support and is easily deformed, the pressure sensor can only be placed on the lumbar support to protect the pressure sensor and its connecting lines. Due to the presence of the mesh fabric, the pressure of the user sitting down cannot be accurately detected, which means that the user's true back pressure cannot be well reflected, resulting in a decrease in user comfort when sitting down. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a lumbar support with good deformability and adjustable position according to the stress on the user's lower back, thereby improving user comfort when sitting.

[0005] This utility model also proposes a seat, including the aforementioned lumbar support.

[0006] The lumbar support according to an embodiment of the present invention includes: a first body, wherein a middle region of the first body is recessed along one side of the thickness direction of the first body to form a recessed space; a second body, wherein the second body is disposed in the recessed space, wherein two ends of the second body are respectively connected to two ends of the first body along the length direction, a portion of the second body is spaced apart from the first body, and the second body is deformable along the recessed direction of the first body; a magnetic component, wherein the magnetic component is disposed on the second body; and a magnetic sensor, wherein the magnetic sensor is disposed on the inner wall of the recessed space, and the magnetic sensor is used to detect the magnetic force of the magnetic component.

[0007] According to an embodiment of the present invention, the lumbar support has a recessed space formed by the middle region of the first body being recessed along one side of its thickness direction along the length direction of the first body. A second body is disposed within the recessed space, with its two ends connected to the two ends of the first body along its length direction. A portion of the second body is spaced apart from the first body, and the second body is deformable along the recessed direction of the first body. A magnetic component is disposed on the second body, and a magnetic sensor is disposed on the inner wall of the recessed space. The magnetic sensor detects the magnetic force of the magnetic component. Due to the presence of the recessed space, the second body can be more easily deformed in the recessed direction, reducing the stiffness of the lumbar support and thus better cushioning the user's lower back, improving comfort when the user sits down. Simultaneously, the magnetic component and magnetic sensor detect the force exerted on the user's lower back when sitting down, and the state of the lumbar support can be adjusted according to the force exerted on the user's lower back, further improving user comfort when sitting down.

[0008] In some embodiments of this utility model, when the second body is not deformed, the magnetic component and the magnetic sensor are arranged opposite to each other in the thickness direction of the first body.

[0009] In some embodiments of this utility model, the magnetic components are a plurality of spaced-apart ones, and the magnetic sensors are a plurality of ones corresponding one-to-one with the plurality of magnetic components.

[0010] In some embodiments of this utility model, the magnetic elements are a plurality of spaced apart along the length direction of the second body; and / or, the magnetic elements are a plurality of spaced apart along the width direction of the second body.

[0011] In some embodiments of this utility model, the first body is a plastic part.

[0012] In some embodiments of this utility model, the second body is a mesh fabric component.

[0014] In some embodiments of this utility model, the diameter of the magnetic element is 25-35mm.

[0015] The seat according to an embodiment of the present utility model includes: a seat body; and the aforementioned lumbar support, wherein the lumbar support is movably disposed on the seat body.

[0016] According to an embodiment of the present invention, the seat, by providing the aforementioned lumbar support, has a recessed space formed by the middle region of the first body recessed along one side of its thickness direction along the length direction of the first body. A second body is disposed within this recessed space, with its two ends connected to the two ends of the first body along its length direction. A portion of the second body is spaced apart from the first body, and the second body is deformable along the recessed direction of the first body. A magnetic component is disposed on the second body, and a magnetic sensor is disposed on the inner wall of the recessed space. The magnetic sensor detects the magnetic force of the magnetic component. Due to the presence of the recessed space, the second body can be more easily deformed in the recessed direction, reducing the stiffness of the lumbar support and thus better cushioning the user's lower back, improving comfort when the user sits down. Simultaneously, the magnetic component and magnetic sensor enable the detection of the force exerted on the user's lower back when sitting down, and the lumbar support can be adjusted according to this force, further improving user comfort when sitting down.

[0017] In some embodiments of this utility model, the seat further includes a drive mechanism, which is disposed on the seat body and connected to the lumbar support for controlling the movement of the lumbar support, and the drive mechanism is communicatively connected to the magnetic sensor.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The following is for reference. Figures 1-3 Description of the lumbar support 10 according to an embodiment of the present utility model.

[0033] like Figures 1-3 As shown, the lumbar support 10 according to an embodiment of the present utility model includes: a first body 1, a second body 2, a magnetic component 3, and a magnetic sensor 4.

[0034] Specifically, refer to Figures 1-3Along the length direction of the first body 1, the middle region of the first body 1 is recessed on one side along the thickness direction of the first body 1 to form a recessed space 11; the second body 2 is disposed in the recessed space 11, the two ends of the length direction of the second body 2 are respectively connected to the two ends of the length direction of the first body 1, a part of the second body 2 is spaced apart from the first body 1, and the second body 2 is deformable along the recessed direction of the first body 1.

[0035] Understandably, when a user sits on the seat, the user's lower back will exert force on the second body 2. Due to the presence of the recessed space 11, the second body 2 can be deformed in the recessed direction, reducing the stiffness of the lumbar support 10, thereby better cushioning the user's lower back and improving the user's comfort when sitting down.

[0036] Furthermore, such as Figures 1-3 As shown, a magnetic component 3 (e.g., a neodymium iron boron component) is disposed on the second body 2; a magnetic sensor 4 (e.g., a Hall sensor) is disposed on the inner wall of the recessed space 11. The magnetic sensor 4 is used to detect the magnetic force of the magnetic component 3. Since the magnetic component 3 is disposed on the second body 2 and the magnetic sensor 4 is disposed on the inner wall of the recessed space 11, when the second body 2 deforms in the recessed direction, the distance between the second body 2 and the magnetic sensor 4 gradually shortens, thereby causing the distance between the magnetic component 3 and the magnetic sensor 4 to gradually shorten. Based on the magnetic force of the magnetic sensor 4, the corresponding pressure value can be converted, and the force on the user's lower back can be obtained. Based on the force on the user's lower back, the state of the lumbar support 10 (e.g., angle and position) can be adjusted, thereby further improving the user's comfort when sitting down.

[0037] It should be noted that due to the presence of the recessed space 11, the user cannot directly apply pressure to the pressure sensor. In this case, the pressure sensor will malfunction, resulting in an inability to accurately detect the force applied to the user when sitting down, and thus an inability to adjust the lumbar support 10 according to the force applied to the user when sitting down, thereby affecting the user's comfort when sitting down. However, this utility model can accurately obtain the change in magnetic force value by changing the distance between the magnetic component 3 and the magnetic sensor 4, and then convert it into a pressure value, thereby realizing the detection of the force applied to the user's lower back when sitting down.

[0038] In addition, the magnetic component 3 can be embedded in the second body 2, or it can be located on the side of the second body 2 facing the magnetic sensor 4 in the thickness direction, or it can be located on the side of the second body 2 away from the magnetic sensor 4 in the thickness direction.

[0039] According to an embodiment of the present invention, the lumbar support 10 has a recessed space 11 formed by the middle region of the first body 1 being recessed along one side of the thickness direction of the first body 1 along its length direction. A second body 2 is disposed in the recessed space 11, with its two ends connected to the two ends of the first body 1 along its length direction. A portion of the second body 2 is spaced apart from the first body 1, and the second body 2 is deformable along the recessed direction of the first body 1. A magnetic component 3 is disposed on the second body 2. A magnetic sensor 4 is disposed on the inner wall of the recessed space 11, and the magnetic sensor 4 is used to detect the magnetic force of the magnetic component 3. Due to the presence of the recessed space 11, the second body 2 can be more easily deformed in the recessed direction, reducing the stiffness of the lumbar support 10 and thus better cushioning the user's lower back, improving user comfort when sitting. Simultaneously, the magnetic component 3 and the magnetic sensor 4 enable the detection of the force on the user's lower back when sitting, and the state of the lumbar support 10 can be adjusted according to the force on the user's lower back, further improving user comfort when sitting.

[0040] In some embodiments of this utility model, such as Figures 1-3 As shown, when the second body 2 is not deformed, the magnetic component 3 and the magnetic sensor 4 are arranged opposite each other in the thickness direction of the first body 1. This increases the magnetic force value detected by the magnetic sensor 4, thereby improving the accuracy of detecting the force on the user's lower back when the user sits down, improving the accuracy of the adjustment state of the lumbar support 10, and further improving the user's comfort when sitting down.

[0041] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, there are multiple spaced-apart magnetic components 3, and multiple magnetic sensors 4 corresponding one-to-one with each of the magnetic components 3. This allows for the detection of the force exerted on the user's lower back at different positions on the lumbar support 10, thereby further improving the accuracy of detecting the force exerted on the user's lower back when seated. Simultaneously, multi-point detection data allows the lumbar support 10 to better adjust its position to adapt to different user postures (posture, weight, etc.) when seated, thus further improving user comfort.

[0042] For example in Figure 1 and Figure 3 In the example shown, there are 6 magnetic components 3 spaced apart, and 6 magnetic sensors 4. However, this invention is not limited to this. The number of magnetic components 3 and magnetic sensors 4 can also be other numbers, such as 3, 5, 14 or 16.

[0043] In some embodiments of this utility model, such as Figures 1-3As shown, the magnetic components 3 are multiple ones spaced apart along the length of the second body 2; thus, the force on the user's lower back at different positions of the lumbar support 10 can be detected along the length of the second body 2, thereby further improving the accuracy of detecting the force on the user's lower back when sitting down. At the same time, the lumbar support 10 can be better adjusted to adapt to different states (posture, weight, etc.) when the user sits down, thereby further improving the user's comfort when sitting down.

[0044] In some embodiments of this utility model, such as Figures 1-3 As shown, the magnetic components 3 are multiple and spaced apart along the width of the second body 2. This allows for the detection of the force exerted on the user's lower back at different positions on the lumbar support 10 along the width of the second body 2, thereby further improving the accuracy of detecting the force exerted on the user's lower back when seated. Simultaneously, multi-point detection data allows for better adjustment of the lumbar support 10 to adapt to different user postures (posture, weight, etc.) when seated, thus further improving user comfort.

[0045] In some embodiments of this utility model, the first body 1 is a plastic component. This ensures both the structural strength and lightweight nature of the first body 1. Furthermore, the fact that the plastic component 3 is non-magnetic avoids interference from the first body 1 with the magnetic sensor 4 and the magnetic component 3, thus preventing deviations in the detection results and ensuring the reliability and accuracy of the detection data.

[0046] In some embodiments of this utility model, the second body 2 is a mesh fabric component. This makes the second body 2 lightweight, and the mesh fabric component is easier to deform and has better elasticity, thereby further improving the user's comfort when seated.

[0047] In some embodiments of this invention, the thickness of the magnetic component 3 is 1-3 mm, such as 1 mm, 2 mm, 2.5 mm, or 3 mm. The thickness of the magnetic component 3 refers to its thickness along the thickness direction of the second body 2. This ensures that the magnetic component 3 has a suitable thickness, guaranteeing its lightness and reducing cost and weight. Simultaneously, it ensures sufficient structural strength to prevent damage to the magnetic component 3.

[0048] In some embodiments of this utility model, the diameter of the magnetic component 3 is 25-35mm, such as 25mm, 30mm, 32mm, or 35mm. It should be noted that the magnetic component 3 is cylindrical, and its diameter refers to the diameter of the end face perpendicular to the thickness direction of the second body 2. This allows the magnetic component 3 to have a suitable diameter, ensuring its lightness and reducing cost and weight. It also ensures sufficient structural strength to prevent damage and that the end face of the magnetic component 3 facing the magnetic sensor 4 is large enough to facilitate better detection of magnetic force by the magnetic sensor 4.

[0049] The following describes a seat according to an embodiment of the present invention.

[0050] The seat according to an embodiment of the present invention includes: a seat body and the aforementioned lumbar support 10, wherein the lumbar support 10 is movably disposed on the seat body. Thus, through the arrangement of the magnetic component 3 and the magnetic sensor 4, the force exerted on the user's lower back when seated is detected, and the state of the lumbar support 10 can be adjusted according to the force exerted on the user's lower back, thereby further improving the user's comfort when seated.

[0051] According to the embodiment of this utility model, the seat, by setting the aforementioned lumbar support 10, forms a recessed space 11 by recessing the middle area of ​​the first body 1 along one side of its thickness direction. A second body 2 is disposed within the recessed space 11, with its two ends connected to the two ends of the first body 1 along its length direction. A portion of the second body 2 is spaced apart from the first body 1, and the second body 2 is deformable along the recessed direction of the first body 1. A magnetic component 3 is disposed on the second body 2. A magnetic sensor 4 is disposed on the inner wall of the recessed space 11, and the magnetic sensor 4 is used to detect the magnetic force of the magnetic component 3. Due to the presence of the recessed space 11, the second body 2 can be more easily deformed in the recessed direction, reducing the stiffness of the lumbar support 10 and thus better cushioning the user's lower back, improving user comfort when sitting. Simultaneously, the magnetic component 3 and the magnetic sensor 4 enable the detection of the force on the user's lower back when sitting, and the state of the lumbar support 10 can be adjusted according to the force on the user's lower back, further improving user comfort when sitting.

[0052] In some embodiments of this utility model, the seat further includes a drive mechanism, which is located on the seat body and connected to the lumbar support 10. The drive mechanism controls the movement of the lumbar support 10 and is communicatively connected to the magnetic sensor 4. This communicative connection can be direct or via a controller, and can be achieved through wireless network, Bluetooth, cable, or other methods. The drive mechanism can be a drive motor, electric cylinder, or similar structure. Therefore, by communicating with the magnetic sensor 4, the seat can adjust the state of the lumbar support 10 according to the pressure on the user's lower back, further improving user comfort when seated.

[0053] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
