Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art. The terms "comprising" and similar expressions used herein mean that the element or object preceding the word covers the element or object listed following the word and its equivalents, but does not exclude other elements or objects.

[0024] To address the problems existing in the prior art, embodiments of the present invention provide a mattress testing device, with reference to... Figure 1 and Figure 2 As shown, the testing device includes a base 100, a support frame 200, a power mechanism 500, and a bionic component 400. The base 100 has a mounting section (not shown) for mounting different test mattresses 300. The support frame 200 is mounted on the base 100 and has a frame structure. The power mechanism 500 is connected to the support frame 200 and has a retractable power output end 521. The extension distance of the power output end 521 is adjustable, and the direction of movement of the power output end 521 is towards the mounting section. The bionic component 400 is connected to the power output end 521. In operation, the extension distance of the power output end 521 continuously adjusts over time. When the bionic component 400 contacts the test mattress 300, it can simulate the body signals or heartbeat signals during human breathing for the test mattress 300 to detect.

[0025] In this embodiment, the mounting part is suitable for mounting different test mattresses 300, thereby improving the applicability of the equipment. Furthermore, the extension distance of the power output end 521 of the power mechanism 500 is adjustable. During operation, the extension distance of the power output end 521 continuously adjusts over time, simulating signals from the human body during breathing or heartbeat, thus improving the accuracy of the test mattress detection.

[0026] Specifically, in this embodiment, the power mechanism 500 includes a servo motor 510 and a linear module 520. The servo motor 510 has an electronic cam function and an output shaft (not shown in the figure). The linear module 520 has a power receiving end (not shown in the figure) and a power output end 521. The power receiving end is connected to the output shaft. Based on the electronic cam function, the servo motor, in conjunction with the linear module, enables the power output end to output according to a predetermined displacement curve. By simulating the heartbeat output signal, the displacement-time curve of the servo motor 510 is set, so that the power receiving end performs corresponding extension and retraction movements according to the displacement-time curve.

[0027] In addition, the testing equipment also includes a host (not shown in the figure), which has a human-machine interface and a control unit. The control unit has a drive module, a force sensing module, and a mattress monitoring module. The control unit is electrically connected to the servo motor 510, the pressure sensor 700, and the test mattress 300.

[0028] The drive module controls the switching of the servo motor 510 and causes the power output terminal 521 of the servo motor 510 to move according to a set displacement-time curve. For example, the drive module can display a switch button on the human-machine interface to control the switching of the servo motor 510. The force sensing module acquires the detection value of the pressure sensor 700 and displays it on the human-machine interface for timely feedback to the operator. The mattress monitoring module detects the measurement data of the test mattress 300 and, based on the measurement data, determines whether the sleep monitoring quality of the test mattress 300 is reliable.

[0029] It should be noted that the test mattress 300 can be any mattress on the market that has a sleep monitoring function.

[0030] In some embodiments, reference is made to Figure 3 As shown, the power mechanism 500 includes a cam 530, a telescopic member 540, a fixed sleeve 550, and a first elastic member 560. The telescopic member 540 is movably inserted into the fixed sleeve 550. The telescopic member 540 has an abutment portion 541 and a telescopic portion 542, the telescopic portion 542 being the power output end 521. The outer wall of the cam 530 abuts against the abutment portion 541. The first elastic member 560 is sleeved between the abutment portion 541 and the fixed sleeve 550, and is used to apply a force to the abutment portion 541 in the direction of the cam 530, allowing the telescopic member 540 to move back. In the working state, the cam 530 rotates, driving the telescopic member 540 to perform telescopic movement, and the telescopic portion 542 drives the bionic component 400 to perform telescopic movement towards the mounting portion.

[0031] It is understood that the shape characteristics of the cam 530 are set according to the heartbeat output signal, that is, when the cam 530 rotates, the displacement-time curve of the telescopic member 540 corresponds to the characteristics of the heartbeat output signal.

[0032] Optional, see reference Figure 1 and Figure 4 As shown, the testing device further includes a second elastic element 600 disposed between the power output end 521 and the bionic component 400. In this embodiment, both the first elastic element 560 and the second elastic element 600 are springs. One end of the second elastic element 600 is fixedly connected to the power output end 521, and the other end of the second elastic element 600 is fixedly connected to the bionic component 400.

[0033] In this embodiment, by setting the second elastic element 600, the displacement of the power output end 521 can be converted into a stable pressure value output, which can effectively filter the high-frequency noise generated by the power mechanism 500, and the generated force value curve is closer to the actual human body, thereby improving the reliability of the test.

[0034] Furthermore, the testing equipment also includes a pressure sensor 700 and a connector 800. The connector 800 has a connecting portion 801 and a connecting hole 802. The connecting hole 802 is located on the side near the power output end 521, and the connecting portion 801 is located on the side near the second elastic member 600, with the connecting hole 802 extending to the connecting portion 801. One end of the pressure sensor 700 is connected to the power output end 521, and the other end of the pressure sensor 700 is connected to the connecting hole 802. The second elastic member 600 is sleeved on the connecting portion 801. That is, the pressure sensor 700, the connector 800, and the second elastic member 600 are sequentially connected between the power output end 521 and the bionic component 400.

[0035] In this embodiment, by setting the pressure sensor 700, it is convenient to detect the pressure value provided by the power output terminal 521 in real time, thereby further improving the reliability of the test.

[0036] Optionally, the testing device further includes a counterweight 900. The bionic component 400 has a fixing part on its side wall near the power output end 521, and the counterweight 900 is detachably disposed on the fixing part.

[0037] In this embodiment, by increasing or decreasing the number of configuration blocks installed, different human body weights can be simulated, improving the comprehensiveness of the simulation test.

[0038] Further reference Figure 5As shown, the bionic component 400 has a protrusion 401 on its side wall near the mounting portion, and the protrusion 401 is a curved surface. That is, the bionic component 400 simulates the characteristics of the human back, further improving the reliability of the test.

[0039] Optionally, the testing equipment also includes a nursing mattress 110. Since the nursing mattress 110 is placed on top of the test mattress 300 during actual use, to further simulate a real usage environment, a layer of the nursing mattress 110 is placed over the test mattress 300, thereby improving the accuracy of the test.
