[0029] The seat 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0030] like Figure 1 As shown, the seat 100 according to an embodiment of the present utility model includes a seat body 1, an armrest 2, a control box 3, and a drive assembly 4.

[0031] Specifically, see the attached document. Figure 1 As shown, the seat body 1 has armrests 2 on both sides along the left and right directions. Pressure sensors 20 are installed inside the armrests 2 to detect the pressure applied by the user. A control box 3 is located on the seat body 1, and the pressure sensors 20 are electrically connected to the control box 3. The control box 3 can receive signals from the pressure sensors 20 inside the two armrests 2. Two drive components 4 are arranged corresponding to the two armrests 2, and are respectively located on the lower side of the two armrests 2. Each drive component 4 includes a first motor 41, a lead screw 42, and a lifting block 43. The first motor 41 is located on the seat body 1 and electrically connected to the control box 3. The lead screw 42 moves along the up and down direction (e.g., ...). Figure 1 (As shown) Extends and is connected to the first motor 41. The first motor 41 drives the lead screw 42 to rotate. The lifting block 43 is sleeved on the lead screw 42 and threadedly engaged with the lead screw 42. The lifting block 43 is connected to the handrail 2 and is used to drive the handrail 2 to move in the up and down direction.

[0032] Understandably, based on the data detected by the pressure sensor 20, the control box 3 calculates the required adjustment range using an algorithm. The first motor 41 starts operating according to the instructions of the control box 3, driving the lead screw 42 to rotate, thereby enabling the lifting block 43 to move vertically relative to the lead screw 42. Since the armrest 2 is fixed on the lifting block 43, the drive component 4 drives the armrest 2 to move vertically, thus achieving real-time detection of the pressure on the armrest 2 and dynamic adjustment of the height of the armrest 2. Precise control of the position of the armrest 2 can improve the inconvenience of manual adjustment, enhance the comfort and personalized experience of the seat 100, improve the intelligence level of the seat 100, and increase the market competitiveness of the seat 100.

[0033] Preferably, the control box 3 is equipped with a button 31 for users to customize the pressure threshold of the armrest 2. It can be understood that when a user sits on the seat 100, they can press the button 31 to put the seat 100 into the smart armrest mode and set a personalized pressure threshold. The armrest 2 will dynamically adjust the first motor 41 according to the detected pressure to achieve the most suitable pressure state, allowing the user's hands to work, study or play in the most comfortable posture.

[0034] It should be noted that the reference appendix Figure 1As shown, the two armrests 2 on the left and right sides of the seat body 1 are height-adjustable via corresponding drive components 4. This allows for independent height control of the two armrests 2, better matching the user's posture. For example, when the user leans to the left, the pressure on the left armrest 2 is relatively greater than that on the right armrest 2. The control box 3 can drive the two first motors 41 on the left and right sides to adjust the height of the two armrests 2, ensuring that the height of the left armrest 2 is lower than that of the right armrest 2. The pressure sensors 20 inside the two armrests 2 and the two drive components 4 can be electrically connected to the same control box 3, thereby simplifying the number of parts in the seat 100 and reducing the assembly difficulty of the seat 100.

[0035] For example, the seat 100 of this utility model can be an office chair, a home chair, a gaming chair, a car seat, etc., to improve its comfort and intelligence level.

[0036] According to the embodiment of the present invention, the seat 100, by providing a pressure sensor 20 in the armrest 2, can detect the pressure applied to the armrest 2 by the user. Based on the data detected by the pressure sensor 20, the control box 3 calculates the required adjustment range through an algorithm and controls the drive component 4 to operate, thereby enabling the drive component 4 to drive the armrest 2 to move in the up and down direction. This achieves real-time detection of the pressure on the armrest 2 and dynamic adjustment of the height of the armrest 2, which can improve the inconvenience of manual adjustment, enhance the comfort and personalized experience of the seat 100, improve the intelligence level of the seat 100, and increase the market competitiveness of the seat 100.

[0037] In some embodiments of this utility model, reference is made to the appendix. Figure 1 As shown, the pressure sensor 20 is a thin-film pressure sensor. A thin-film pressure sensor is a sensor that uses a thin-film material as a sensitive element to convert pressure signals into electrical signals. Thin-film pressure sensors are flexible and can easily conform to the shape of the handrail 2, improving the detection effect of the pressure sensor. Thin-film pressure sensors are small in size and light in weight, which facilitates the integration of pressure sensor 20 and can reduce the user's foreign body sensation.

[0038] Of course, this utility model is not limited to this. The pressure sensor 20 can also be other types and precision pressure sensors 20, which can be matched with different application environments and user needs.

[0039] In some embodiments of this utility model, reference is made to the appendix. Figure 1 As shown, the handrail 2 includes a support portion 21 and a handrail portion 22. The support portion 21 extends in the vertical direction, and its lower end is connected to the lifting block 43. The handrail portion 22 is connected to the upper end of the support portion 21 and extends in the front-back direction (e.g., ...). Figure 1As shown, when a user sits on the seat 100, their elbow is supported on the armrest 22, and their forearm extends roughly in the front-back direction. This allows the armrest 22 to extend in the front-back direction, better matching the elbow and forearm and providing better support for the user's arm. The pressure sensor 20 is located inside the armrest 22, which can better sense the pressure applied by the user's arm to the armrest 22, ensuring the accuracy of the pressure sensor 20.

[0040] In a further embodiment of this utility model, the armrest 22 includes a frame and a cover. The lower surface of the frame is connected to the support 21. As the main load-bearing structure of the armrest 22, the frame needs to withstand the pressure of the user's arm, elbow, or even body (such as when leaning against it). The cover is wrapped around the upper surface of the frame and directly contacts the user. This can ensure structural safety while taking into account user experience and aesthetic requirements, improving the comfort and durability of the seat 100, and extending the service life of the seat 100.

[0041] Furthermore, the pressure sensor 20 is located between the skin and the frame. When the user touches the skin, the skin is deformed by pressure, squeezing the pressure sensor 20. The pressure sensor 20 converts the pressure signal into an electrical signal and transmits it to the control box 3. The control box 3 triggers the corresponding function according to the signal. It can be understood that the pressure sensor 20 is a thin-film pressure sensor 20 and is bonded to the lower surface of the skin. It can fit closely to the skin and bend with the skin to accurately capture the contact between the user and the armrest 22 (such as arm placement and leaning force), avoiding signal attenuation caused by excessive skin thickness or material cushioning.

[0042] In a further embodiment of this utility model, the armrest 22 is provided with multiple pressure sensors 20, all of which are electrically connected to the control box 3. The signals from the multiple pressure sensors 20 can be transmitted to the control box 3, and the control box 3 controls the raising and lowering of the armrest 2 based on the collected data. The arrangement of multiple pressure sensors 20 can improve the coverage of pressure detection, refine pressure detection and positioning, and help the control box 3 better control the raising and lowering of the armrest 2. For example, the pressure sensors 20 can be two, three, four, or five spaced apart.

[0043] In a further embodiment of this utility model, multiple pressure sensors 20 inside the armrest 22 are arranged in a matrix along the horizontal direction, which can accurately locate the contact position of the user's arm or elbow, realize regional pressure detection, and help the control box 3 better control the lifting and lowering of the armrest 2.

[0044] In a further embodiment of this invention, multiple pressure sensors 20 within the armrest 22 are arranged along the front-to-back direction. The armrest 22 is rotatably connected to the support 21. It is understood that by detecting pressure at different positions of the armrest 22 in the front-to-back direction, when the pressure at the front end of the armrest 22 exceeds the pressure at the rear end by a certain value, the front end of the armrest 22 is driven to rotate downwards relative to the rear end. Conversely, when the pressure at the rear end of the armrest 22 exceeds the pressure at the front end by a certain value, the front end of the armrest 22 is driven to rotate upwards relative to the rear end. This allows adjustment of the support angle of the entire armrest 22 for the user's arm, improving user comfort and enhancing the user experience.

[0045] In a further embodiment of this utility model, the armrest 2 also includes a second motor, which is mounted on the support 21 and electrically connected to the control box 3. The second motor is used to drive the armrest 22 to rotate relative to the support 21. The signals detected by the multiple pressure sensors 20 can be transmitted to the control box 3. The control box 3 can drive the second motor to rotate forward, reverse, or remain stationary by judging the signals, so as to change the support angle of the armrest 22 for the user's arm and ensure the reliability of the rotation of the armrest 22 relative to the support 21.

[0046] In some embodiments of this utility model, reference is made to the appendix. Figure 1 As shown, the drive assembly 4 also includes a sleeve 44, which is mounted on the seat body 1 and extends vertically. The lead screw 42 and the lifting block 43 are movably mounted inside the sleeve 44. The lower end of the armrest 2 extends into the sleeve 44. The sleeve 44 can shield components such as the lead screw 42 and the lifting block 43, preventing them from being directly exposed, thus improving the overall aesthetics of the seat 100. It also prevents foreign objects and dust from affecting the coordination between the first motor 41, the lead screw 42, the lifting block 43, and the armrest 2, ensuring the reliability of the drive assembly 4 in adjusting the armrest 2, extending the service life of the seat 100, and preventing the operation of components from causing injury to the user.

[0047] In some embodiments of this utility model, reference is made to the appendix. Figure 1 As shown, the control box 3 is located on the seat cushion 11 of the seat body 1 and on one side of the seat cushion 11 in the left and right direction. This allows the user to easily access the control box 3 when sitting on the seat 100, making it convenient for the user to adjust the pressure threshold of the armrest 2 while sitting. This allows the user to feel the support force of the armrest 2 while sitting, reducing the difficulty for the user to adjust the armrest 2 to a suitable support force and improving the user experience.
