[0036] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0037] Reference below Figure 1-Figure 6 A seat 100 according to an embodiment of a first aspect of the present invention is described.

[0038] like Figure 1 and Figure 2 As shown, the seat 100 according to the first embodiment of the present invention comprises: a cushion portion 10, a backrest portion 20, a first support member 30, a second support member 40, a first drive member, a second drive member and a control unit.

[0039] Specifically, the backrest portion 20 is connected to the cushion portion 10, the first support member 30 and the second support member 40 are disposed on the front side of the backrest portion 20 and are arranged in sequence up and down, the first support member 30 is provided with a first pressure sensor, the second support member 40 is provided with a second pressure sensor, the first support member 30 and the second support member 40 are both movable in the front-to-back direction relative to the cushion portion 10, the first driving member is used to drive the first support member 30 to move in the front-to-back direction relative to the cushion portion 10, the second driving member is used to drive the second support member 40 to move in the front-to-back direction relative to the cushion portion 10, and the control unit is electrically connected to the first pressure sensor, the second pressure sensor, the first driving member and the second driving member.

[0040] The first support member 30 and the second support member 40 are supported at different upper and lower parts of the rear side of the user. For example, the first support member 30 can be supported at the back area and shoulder area of ​​the user, and the second support member 40 is supported at the waist area of ​​the user. The first pressure sensor is used to detect the pressure on the first support member 30, and the second pressure sensor is used to detect the pressure on the second support member 40. The control unit receives data from the first pressure sensor and the second pressure sensor, and issues instructions to the first driving member and the second driving member according to the data.

[0041] During use by the user, the first pressure sensor and the second pressure sensor respectively detect the pressure applied by the user to the first support member 30 and the second support member 40, and transmit the pressure data to the control unit. When the user's sitting posture changes, causing the front-to-back distance of the user relative to the backrest 20 to change, the pressure applied by the user to the first support member 30 and the second support member 40 will also change. At this time, the control unit issues instructions to the first drive member and the second drive member based on the pressure data, so that the first support member 30 and the second support member 40 move relative to the cushion portion 10 in the front-to-back direction, so that the first support member 30 and the second support member 40 fit the rear side of the user to a set degree. In this way, the first support member 30 and the second support member 40 can automatically track the user and maintain support for the user during use.

[0042] It is understandable that the support force required by the user is different at different positions behind the user. By setting the first support member 30 and the second support member 40 arranged up and down, different positions behind the user can be tracked and different support forces can be applied respectively during the operation of the seat 100. At the same time, the position adjustment of the first support member 30 and the second support member 40 relative to the cushion part 10 in the front-to-back direction can make the support curve of the seat 100 more in line with the requirements of ergonomics. For example, the first support member 30 supports the back of the user, and the second support member 40 supports the waist of the user. During the use of the user, the front-to-back position of the first support member 30 and the second support member 40 can be adapted to the user's sitting posture according to the user's sitting posture.

[0043] According to the chair 100 of the first aspect of the present invention, on the one hand, when the user's sitting posture changes, the first support member 30 and the second support member 40 can automatically track the user and maintain support for the back of the user. On the other hand, the first support member 30 and the second support member 40 can provide differentiated support to the user at the upper and lower positions, making the chair 100 more ergonomic, thereby improving the user's experience.

[0044] In some embodiments of the present invention, the first support member 30 is fixedly connected to the backrest portion 20, the backrest portion 20 is movably connected to the cushion portion 10 forward and backward, and the first driving member is provided on the cushion portion 10, and the first driving member is suitable for driving the backrest portion 20 to move forward and backward on the cushion portion 10.

[0045] In this way, the first support member 30 can be moved in the front-to-back direction relative to the cushion portion 10, wherein it can be understood that the first support member 30 is arranged on the upper side of the second support member 40, the first support member 30 is close to the back area and shoulder area of ​​the user, and the second support member 40 is close to the waist area of ​​the user. When the user's sitting posture changes, the back area and shoulder area of ​​the user will undergo a large displacement. It can be understood that when the distance between the first support member 30 and the backrest 20 is too large, the stability of the seat 100 will be poor. The front-to-back movement of the first support member 30 relative to the cushion portion 10 is achieved by moving the backrest 20 forward and backward relative to the cushion portion 10. The distance between the first support member 30 and the backrest 20 does not change, which can improve the stability of the seat 100 during operation, thereby further improving the user experience.

[0046] In some embodiments of the present invention, one of the backrest portion 20 and the cushion portion 10 is provided with a first slide rail extending forward and backward, and the other is provided with a first slide groove extending forward and backward, and the first slide rail is fitted in the first slide groove.

[0047] Therefore, the first slide rail and the first slide groove can cooperate to limit and guide the cushion part 10, so that the backrest part 20 can move along the front and rear direction on the cushion part 10, and the cooperation between the first slide rail and the first slide groove is relatively simple, which can reduce the difficulty of product design and production.

[0048] In some embodiments of the present invention, the second support member 40 is movably connected to the backrest 20 , and the second driving member is disposed on the backrest 20 , and the second driving member is suitable for driving the second support member 40 to move forward and backward on the backrest 20 .

[0049] In this way, the second support member 40 can be moved in the front-to-back direction relative to the cushion portion 10. It can be understood that the second support member 40 is close to the user's waist area. When the user adjusts his sitting posture, the user's waist area is displaced less. In this way, the path of the second support member 40 moving back and forth on the backrest 20 is also shorter, and the distance between the second support member 40 and the backrest 20 will not be large, which can ensure the stability of the seat 100 during operation. In addition, the differentiated position adjustment of the first support member 30 and the second support member 40 in the front-to-back direction can be achieved, so that the support curve of the seat 100 is more ergonomic.

[0050] In some embodiments of the present invention, one of the second support member 40 and the backrest portion 20 is provided with a second slide rail extending forward and backward, and the other is provided with a second slide groove extending forward and backward, and the second slide rail is fitted in the second slide groove.

[0051] Therefore, the second slide rail and the second slide groove can cooperate to limit and guide the second support member 40, so that the second support member 40 can move along the front and rear direction on the backrest 20, and the cooperation between the second slide rail and the second slide groove is relatively simple, which can reduce the difficulty of product design and production.

[0052] In some embodiments of the present invention, the first driving member is a linear motor. In this way, the linear motor is used to realize the linear motion of the backrest portion 20 on the seat cushion portion 10, which is relatively simple to implement and can simplify the structure of the seat 100, thereby further reducing the difficulty of product design and production.

[0053] In some embodiments of the present invention, the second driving member is a linear motor. Thus, the linear motor is used to realize the linear motion of the second support member 40 on the backrest 20, which is simple to implement and can simplify the structure of the seat 100, thereby further reducing the difficulty of product design and production.

[0054] In some embodiments of the present invention, the seat 100 further includes: a third pressure sensor, which is disposed on the cushion portion 10. By providing the third pressure sensor, the third pressure sensor can detect whether someone is sitting on the seat 100. When the seat 100 is idle, the seat 100 can be put into a standby state, thereby reducing the energy consumption of the seat 100.

[0055] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the seat 100 further includes: a support leg 50, and the cushion portion 10 is supported on the support leg 50 in an adjustable manner. Thus, the seat 100 can meet more usage needs of the user and further improve the user's usage experience.

[0056] In some embodiments of the present invention, the cushion portion 10 is movably disposed on the support leg 50, and the chair 100 further includes: a third driving member, which is used to drive the cushion portion 10 to move up and down on the support leg 50. In this way, the height of the chair 100 can be automatically adjusted, thereby further improving the user experience.

[0057] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the support leg 50 is provided with a first slide 51 and a second slide extending up and down, the first slide 51 is sleeved on the outside of the second slide, the second slide can move up and down in the first slide 51 and extend upward from the first slide 51, and the extended end of the second slide is connected to the cushion part 10.

[0058] Therefore, the first slide cylinder 51 and the second slide cylinder can cooperate to limit and guide the cushion part 10, so that the cushion part 10 moves along the up and down directions on the support leg 50, and the cooperation between the first slide cylinder 51 and the second slide cylinder is relatively simple, which can reduce the difficulty of product design and production.

[0059] In some embodiments of the present invention, the third driving member is a linear motor. In this way, the linear motor is used to realize the linear motion of the cushion portion 10 on the support leg 50, which is relatively simple to implement and can simplify the structure of the seat 100, thereby further reducing the difficulty of product design and production.

[0060] In some embodiments of the present invention, the seat 100 also includes: an operation panel, which is electrically connected to the control unit. During user use, the operation panel can display the working status of the seat 100, and the user can manually operate the seat 100 through the operation panel, thereby meeting more user needs and further improving the user experience.

[0061] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the middle portion of the first support member 30 is recessed backward to form a first support groove extending up and down and penetrating the first support member 30 up and down. During use by the user, the back area and shoulder area of ​​the user can be supported in the first support groove. In this way, the first support member 30 can wrap the back area and shoulder area of ​​the user from both sides, thereby improving the user's stability on the seat 100 and enhancing the user's comfort.

[0062] The middle portion of the second support member 40 is recessed backward to form a second support groove extending up and down and penetrating the second support member 40 up and down. During use by the user, the user's waist area can be supported in the second support groove. In this way, the second support member 40 can wrap the user's waist area from both sides, thereby improving the user's stability on the seat 100 and enhancing the user's comfort.

[0063] Reference below Figure 1-Figure 6 A control method for the seat 100 according to an embodiment of the second aspect of the present invention will be described.

[0064] The control method of the seat 100 according to the second aspect of the present invention is applied to the seat 100 according to the first aspect of the present invention. Figure 3 As shown, the control method includes:

[0065] S1. Obtain a first pressure on the first support member 30 , and obtain a second pressure on the second support member 40 .

[0066] After the user sits on the seat 100 , the first pressure sensor detects the pressure of the user on the first support member 30 , and the second pressure sensor detects the pressure of the user on the second support member 40 .

[0067] S2. Control the position of the first support member 30 relative to the seat cushion portion 10 in the front-rear direction according to the first pressure, and control the position of the second support member 40 relative to the seat cushion portion 10 in the front-rear direction according to the second pressure.

[0068] During the operation of the seat 100, the control unit determines the user's sitting posture according to the values ​​of the first pressure and the second pressure. When the control unit determines that the user's sitting posture is adjusted, the control unit sends instructions to the first drive member and the second drive member. The first drive member and the second drive member drive the first support member 30 and the second support member 40 to adjust their positions relative to the cushion portion 10 in the front-rear direction according to the instructions of the control unit. At the same time, the first sensor and the second sensor detect the user's first pressure on the first support member 30 and the second pressure on the second support member 40 in real time. When the control unit determines that the user's sitting posture is stable and the first support member 30 and the second support member 40 provide stable support for the user according to the values ​​of the first pressure and the second pressure, the control unit controls the first drive member and the second drive member to stop working. In this way, the first support member 30 and the second support member 40 automatically track the user's sitting posture.

[0069] According to the control method of the chair 100 of the second aspect of the present invention, when the user's sitting posture changes, the first support member 30 and the second support member 40 can automatically track the user and maintain support for the back of the user.

[0070] In some embodiments of the present invention, Figure 4 As shown, controlling the position of the first support member 30 relative to the cushion portion 10 in the front-rear direction according to the first pressure includes:

[0071] S21, comparing the first pressure and the first threshold value P1 and the second threshold value P2, P1<P2;

[0072] S22: If the first pressure is less than P1, the first support member 30 is controlled to move forward relative to the cushion portion 10.

[0073] If P1≤first pressure≤P2, the first support member 30 is relatively fixed to the cushion portion 10.

[0074] If the first pressure>P2, the first support member 30 is controlled to move backward relative to the seat cushion portion 10.

[0075] It is understandable that during use, when the user leans on the first support member 30 in a stable sitting position, the pressure range of the user on the first support member 30 is determined, that is, the range of the first pressure of the user on the first support member 30 is P1-P2.

[0076] When the user leans forward, the force exerted by the user on the first support member 30 will decrease. When the first pressure exerted by the user on the first support member 30 is less than P1, the control unit determines that the user is leaning forward, and the control unit sends a command to the first driving member, so that the first driving member drives the first support member 30 to move forward relative to the cushion portion 10 and gradually fits with the rear side of the user. When the first pressure is greater than P1, the control unit controls the first driving member to stop driving.

[0077] When the user wants to lean back, the force exerted by the user on the first support member 30 will increase. When the first pressure exerted by the user on the first support member 30 is greater than P2, the control unit determines that the user is leaning back, and the control unit sends a command to the first driving member to drive the first supporting member 30 to move backward relative to the cushion portion 10. When the first pressure is less than P2, the control unit controls the first driving member to stop driving.

[0078] Among them, it can be understood by those skilled in the art that the value of the first pressure is positively correlated with the weight of the user, and the values ​​of P1 and P2 are positively correlated with the gravity G of the user. The research data that has been made public in the industry point out that when the user is in a stable sitting position, the pressure range of the user on the backrest 20 of the seat 100 is 25%-56% of the user's gravity G. In the process of product design, 26% of the G value can be used as the reference value of P1, and 56% of the G value can be used as the reference value of P2, and they can be optimized according to the actual experience of the user.

[0079] In some embodiments of the present invention, Figure 5 As shown, controlling the position of the second support member 40 relative to the cushion portion 10 in the front-rear direction according to the second pressure includes:

[0080] S23, comparing the second pressure with the third threshold value P3 and the fourth threshold value P4, P3<P4;

[0081] S24: If the second pressure is less than P3, the second support member 40 is controlled to move forward relative to the cushion portion 10.

[0082] If P3≤second pressure≤P4, the second support member 40 is relatively fixed to the cushion portion 10.

[0083] If the second pressure>P4, the second support member 40 is controlled to move backward relative to the seat cushion portion 10.

[0084] It is understandable that during use, when the user leans on the second support member 40 in a stable sitting position, the pressure range of the user on the second support member 40 is determined, that is, the second pressure range of the user on the second support member 40 at this time is P3-P4.

[0085] When the user leans forward, the force exerted by the user on the second support member 40 will decrease. When the second pressure exerted by the user on the second support member 40 is less than P3, the control unit determines that the user is leaning forward, and the control unit sends a command to the second drive member, so that the second drive member drives the second support member 40 to move forward relative to the cushion portion 10 and gradually fits with the rear side of the user. When the second pressure is greater than P3, the control unit controls the second drive member to stop driving.

[0086] When the user wants to lean back, the force exerted by the user on the second support member 40 will increase. When the second pressure exerted by the user on the second support member 40 is greater than P4, the control unit determines that the user is leaning back, and the control unit sends a command to the second drive member to drive the second support member 40 to move backward relative to the cushion portion 10. When the second pressure is less than P4, the control unit controls the second drive member to stop driving.

[0087] Among them, it can be understood by those skilled in the art that the value of the second pressure is positively correlated with the user's weight, and the values ​​of P3 and P4 are positively correlated with the user's gravity G. The research data that has been made public in the industry point out that when the user is in a stable sitting position, the pressure range of the user on the backrest 20 of the seat 100 is 25%-56% of the user's gravity G. In the process of product design, 26% of the G value can be used as the reference value of P3, and 56% of the G value can be used as the reference value of P4, and they can be optimized according to the actual experience of the user.

[0088] In some embodiments of the present invention, Figure 6 As shown, the seat 100 further includes: a third pressure sensor, which is disposed on the seat cushion portion 10, and before step S1, further includes:

[0089] S01, obtaining a third pressure on the cushion portion 10;

[0090] S02, comparing the third pressure with the fifth threshold value P5,

[0091] If the third pressure is greater than P5, it is determined that someone is sitting on the seat cushion 10, and the process goes to step S1.

[0092] When no one sits on the seat 100 , the seat 100 is in a standby state, and the third pressure sensor detects the pressure on the cushion portion 10 . When the third pressure is greater than P5 , the control unit controls the seat 100 to enter a working state, thereby saving energy consumption of the seat 100 .

[0093] Among them, seat 100 can be a work chair or a children's chair. During the product design process, different values ​​of P5 are set according to the average weight of the people for whom seat 100 is applicable. For example, P2 can be 50% of the weight of the applicable people. In this way, misjudgment caused by weight differences among users of different body shapes can be reduced.

[0094] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “clockwise”, “counterclockwise”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0095] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.
