Problems solved by technology

In addition, there is another evaluation method that reflects the independent support of mattresses and the human body fit between people and beds through customer experience, but this method is greatly affected by the subjective impression of the human body and the degree of personal grasp, and cannot objectively reflect The support performance of the mattress to the human body

Embodiment 1

[0040] Based on the above theoretical basis, see Figure 1-6 : a kind of mattress fitting degree quantitative testing equipment of the present embodiment, comprises test platform 1, mobile support 2, mechanical performance testing device 3, several groups of grating displacement sensors 4, main frame 5, and described mobile support 2 is installed on the test On the platform 1 and can move back and forth, the mobile support 2 is provided with several groups of grating displacement sensors 4 facing vertically downward and a mechanical performance testing device 3 for synchronously measuring the deformation of various positions and surroundings of the mattress under different loads Quantitative and deformation waves, the several groups of grating displacement sensors 4 and mechanical performance testing devices 3 are connected to the host computer 5 through their respective lines. This embodiment provides a quantitative test for mattress fit (shapeability), bed Test equipment and...

Embodiment 2

[0042] A quantitative testing device for mattress fitting degree of this embodiment is basically the same as that of Embodiment 1, the main difference is that the test platform 1 includes a surrounding support 11 and a rigid table 12 with holes in the middle, and the surrounding The bracket 11 includes an upper bracket and a lower bracket, wherein the top of the upper bracket is provided with a rigid table 12 with a hole in the middle, and the lower end of the rigid table 12 with a hole in the middle is fixed to match the lower bracket, and the middle part of each side of the lower bracket has a Gas channel 14, the lower edge of gas channel 14 is at least 50mm from the ground, the diameter of the hole on the rigid table 12 is 6mm, and the spacing is 20mm, so as to discharge the gas generated during the test in time. The ground is at least 150 mm. The mobile support 2 includes a support beam 21 and upright columns 22 arranged on both sides. The support beam 21 has an empty slot ...

Embodiment 3

[0046] In order to simulate the forces of different weights and fat and thin human bodies on various points on the mattress, 90N, 140N, and 190N were respectively selected as the force loads of the test points on the mattress.

[0047] The present invention also discloses a quantitative test method for the fit degree of the mattress, the method comprising the following steps:

[0048] (1) First, before testing, place the mattress at room temperature (23±2)°C and relative humidity (50±5)% for 24 hours (to adapt to the environment);

[0049] (2) Then, place the whole mattress on the test platform, adjust the indenter to be in close contact with the mattress, and add gaskets with grooves at the lower ends of the three grating displacement sensors;

[0050] (3) During the test, first pre-press the mattress, load 100N, load speed 20mm / min, repeat loading and unloading 3 times;

[0051] (4) Then load to 40N, record the indenter displacement (a0) and the initial displacement (b0, c0...

Abstract

The invention discloses a mattress fitting degree quantitative test device. The device comprises a test platform, a movable support, a mechanical property test device, a plurality of grating displacement sensors and a host. The movable support is mounted on the test platform and can move back and forth. The vertically downward grating displacement sensors are arranged on the movable support, the mechanical property test device is used for synchronously measuring deformation amount and deformation waves at different positions and around a mattress under different loads, and the grating displacement sensors and the mechanical property test device are connected with the host through respective circuits. The invention also discloses a mattress fitting degree quantitative test method and an evaluation method. According to the invention, the fitting degree of the mattress is defined from the angle of the physical support characteristics of the mattress, so that the fitting degree of the mattress is favorably optimized through adjustment of the physical characteristics of the mattress, and the humanized design and customized production of the mattress are realized.

Description

technical field [0001] The invention relates to the technical field of mattress fitting degree testing, in particular to a quantitative testing device, method and evaluation method for mattress fitting degree. Background technique [0002] At present, there are many kinds of mattresses on the market with different performances, but each mattress is advertised as being able to fit the human body perfectly, ensuring that the spine is in a state of natural curvature, which is beneficial to the health of the spine. It is true that the perfect fit of the mattress to the human body is the prerequisite for effective support of all points of the spine, and it also reflects the high-quality plasticity of the mattress, and the high-quality plasticity of the mattress is that all parts of the human body are evenly supported in the sleeping position guarantee. Therefore, evaluating the fit of mattresses from the perspective of mattress support performance is of great significance for th...
