Problems solved by technology

[0004] The purpose of the present invention is to provide a chair with an anti-dumping function in order to solve the above-mentioned technical problems of low integrity and low stability in chairs with existing structures. The chair of the present invention can automatically provide assistance for the legs of the chair through the principle of numerical control. The supporting force ensures that the chair legs do not roll over or back, which improves the stability and safety of the chair

Embodiment 1

[0035] Such as figure 1 As shown, the chair in this embodiment includes: a chair body 1 , a pressure sensor 2 , a tilt state monitor 3 , a central controller (not shown) and an auxiliary supporting mechanism 4 . A chair based on the above structure, such as figure 2 As shown, the inclination state monitor 3 can be arranged at the center of the bottom surface of the seat, and the inclination state monitor 3 can adopt an inclination sensor, which senses the position of the chair body 1 in the set plane coordinate system. angular displacement.

[0036] Further, such as image 3 As shown, the central controller may include: a signal acquisition module, a signal preprocessing module, a data analysis module and a driving module.

[0037] The signal acquisition module is used to collect the induction signals output by the pressure sensor 2 and the inclination sensor;

[0038] The signal preprocessing module is used to preprocess the sensing signal to generate a signal for identi...

Embodiment 2

[0050] The chair in this embodiment also includes figure 1 The chair body 1 , the pressure sensor 2 , the tilt state monitor 3 , the central controller (not shown) and the auxiliary supporting mechanism 4 shown in the chair. The difference with the chair structure in Embodiment 1 is that the tilt state monitor 3 in the present embodiment adopts a displacement sensor; Figure 6 As shown, displacement sensors are provided at the corners of each side of the chair body 1, and the displacement sensors sense the linear displacement of their positions within the set three-axis coordinate system in space.

[0051] Use multiple displacement sensors to set signal markers at the corners of the chair. When the position or state of the chair changes, the spatial position of the signal markers will change. At this time, the data analysis module will analyze each signal after the position change. The marked points are connected, and compared with the corresponding signal marked points in th...

Abstract

The invention provides a chair with an anti-toppling function. The chair with the anti-toppling function comprises a chair body (1), a pressure sensor (2), an inclined state monitor (3), and a centralcontroller and auxiliary supporting mechanisms (4); the pressure sensor (2) is used for sensing the stress degree of chair legs and generating pressure data; the inclined state monitor (3) is used for sensing the inclined state of the chair body (1) and generating inclined data; the auxiliary supporting mechanisms (4) are arranged between any two of adjacent chair legs and used for providing an auxiliary supporting force for the inclined-state chair; and the central controller is used for analyzing the pressure data and the inclined data of the chair legs and adjusting the elongation quantityand the pointed angle of each auxiliary supporting mechanism (4) according to the analysis result. The chair can monitor the state of the chair in real time, can drive the auxiliary supporting mechanisms through monitoring data to give the chair supporting force from the toppling direction of the chair, can prevent the chair from toppling and improves the use stability and safety of chair.

Description

technical field [0001] The invention relates to the technical field of seat safety, in particular to a chair with an anti-dumping function. Background technique [0002] Chair is a common piece of furniture in daily life. As an auxiliary part for rest, the chair has a solid structure and stability, and its safety is the primary requirement of users. For active children, they often climb on the chair to play, leaning against the backrest and shaking around, and the backrest will be unstable when the force exceeds a certain range, and even roll back or roll over. Children are at risk for safety. [0003] In order to solve the above problems, some manufacturers have specially designed auxiliary support parts on chairs, which are connected with chair legs by springs, so that the auxiliary support parts are stretched outwards at a certain angle due to gravity. However, the auxiliary supporting parts of this structure cause the chair to swing back and forth due to the offset of ...
