Description

Technical Field

[0001] This utility model relates to the field of massage chair testing technology, and in particular to a noise testing device for massage chairs. Background Technology

[0002] As people's living standards improve, the market demand for massage chairs, as a home health care device that relieves fatigue and promotes health, is growing. The quietness of massage chairs is one of the important indicators for measuring their quality. Good quiet design can improve the user experience and avoid noise interference during use. Therefore, it is crucial to accurately test the quietness of massage chairs during the production process.

[0003] Existing testing platforms typically lack effective positioning devices, and massage chairs are prone to displacement during testing, resulting in inconsistent test positions each time. This makes the test results incomparable and inaccurate, and cannot truly reflect the noise reduction performance of the massage chair. Existing testing equipment has a simple arrangement of noise sensors, usually only setting a few sensors in fixed positions, which makes it difficult to comprehensively capture the noise generated by various parts of the massage chair. To solve the above problems, this application proposes a noise reduction testing device for massage chairs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a noise testing device for massage chairs. This device uses a clamping mechanism to allow the C-shaped clamps on both sides to move relative to each other and precisely press against the chair base, ensuring that the massage chair is fixed in the same position for each test, thus improving the comparability and accuracy of the test results. Multiple noise sensors are installed on the bottom of the test dummy to collect noise from various parts of the massage chair during operation from all angles, avoiding the limitations of single-point measurement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0014] 2. Multiple hydraulic rods drive the test dummy to simulate a human lying down, working in conjunction with the massage chair, which is closer to the actual use scenario and makes the test data more valuable.

[0015] 3. Multiple noise sensors on the bottom of the test dummy can collect noise from various parts of the massage chair during operation from all angles, avoiding the limitations of single-point measurement.

[0016] 4. The display panel can present the data collected by the noise sensor in real time and intuitively, which is convenient for staff to quickly analyze and evaluate; the components of this device work together, the operation process is simple, the manual adjustment steps are reduced, and the testing efficiency is effectively improved.

[0017] In summary, this device uses a clamping mechanism to allow the C-shaped clamps on both sides to move relative to each other and precisely press against the chair base, ensuring that the massage chair is fixed in the same position for each test, thus improving the comparability and accuracy of the test results. Multiple noise sensors are installed on the bottom of the test dummy to collect noise from various parts of the massage chair during operation from all angles, avoiding the limitations of single-point measurement.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4 A noise testing device for a massage chair includes a test platform 1, a chair base 2 placed on top of the test platform 1, a slope on one side of the test platform 1 to facilitate pushing the massage chair body 3 onto the test platform 1, multiple casters installed at the bottom of the chair base 2, the bottoms of the multiple casters abutting against the top of the test platform 1, and the massage chair body 3 fixedly connected to the top of the chair base 2. The slope of the test platform 1 is used to assist the massage chair body 3 in rolling to the top of the test platform 1 via the casters of the chair base 2.

[0025] A C-shaped plate 4 is fixedly connected to the side wall of the test platform 1. A multi-section hydraulic rod 5 is fixedly connected to the C-shaped plate 4. The multi-section hydraulic rod 5 drives the test dummy 6 to rise and fall by telescopic movement. The test dummy 6 is placed on the massage chair body 3 for testing. The massage chair body 3 can be replaced by removing the test dummy 6 from the massage chair body 3. The test dummy 6 is fixedly connected to the bottom of the multi-section hydraulic rod 5. The test dummy 6 cooperates with the massage chair body 3. Multiple noise sensors 7 are installed on the bottom of the test dummy 6. The noise sensors 7 collect the noise data generated by the massage chair body 3 when it is working. Sensors are added to different parts of the massage chair to improve the accuracy of the test. Multiple grooves are opened on the bottom of the test dummy 6. The noise sensors 7 are located in the grooves and are fixedly installed with them by adhesive. A display panel 8 is fixedly connected to the side wall of the C-shaped plate 4. The display panel 8 receives and displays the data collected by the noise sensors 7. The display panel 8 can control the opening and closing of the multi-section hydraulic rod 5.

[0026] A rotating rod 9 is rotatably connected to the test platform 1. A handle 15 is fixedly connected to the end of the rotating rod 9 away from the test platform 1. Two clamping mechanisms are provided on the rotating rod 9. Each clamping mechanism includes a first limiting block 12 fixedly connected to the top of the test platform 1. A threaded rod 11 rotatably connects to the first limiting block 12. A synchronous belt 10 is fitted on the outer wall of the rotating rod 9 and the outer wall of the threaded rod 11. A driving pulley is fixedly connected to the outer wall of the rotating rod 9, and a driven pulley is fixedly connected to the outer wall of the threaded rod 11. The synchronous belt 10 is fitted on the outer walls of the driving pulley and the driven pulley. A movable column 13 threadedly connected to the outer wall of the threaded rod 11 is fitted on the outer wall of the threaded rod 11. The threads of the two threaded rods 11 are arranged in opposite directions. The cross section of the movable column 13 is... The test platform 1 is rectangular in shape. A second limiting block 14 is fixedly connected to the top of the test platform 1. A moving column 13 passes through the second limiting block 14 and is slidably connected to it. A C-shaped clamp 16 is fixedly connected to the end of the moving column 13 away from the threaded rod 11. The handle 15 drives the rotating rod 9 to rotate. The synchronous belt 10 links the rotating rod 9 with the threaded rod 11 through the driving pulley and the driven pulley. The first limiting block 12 restricts the threaded rod 11 to rotate only. The second limiting block 14 cooperates with the rectangular cross section of the moving column 13 to restrict the moving column 13 to move only along the axial direction of the threaded rod 11. The threaded rod 11 with opposite thread directions causes the moving columns 13 on both sides to drive the C-shaped clamp 16 to move synchronously relative to each other or in opposite directions. The C-shaped clamp 16 is used to press against the chair base 2 to achieve the positioning of the massage chair body 3.

[0027] In this invention, the operator pushes the massage chair body 3 to the top of the test platform 1, positions the chair base 2 between the two C-shaped clamps 16, and rotates the handle 15 to rotate the rotating rod 9, the two synchronous belts 10, and the threaded rod 11, causing the moving columns 13 on both sides and the C-shaped clamps 16 to move relative to each other until the two C-shaped clamps 16 abut against the sides of the chair base 2, and the inner walls of the two C-shaped clamps 16 abut against the four right-angled sides of the chair base 2, thus completing the clamping and limiting of the chair base 2 and ensuring that the massage chair body 3 is fixed in the same position each time. The operator activates the multi-section hydraulic rod 5 through the operation display panel 8, and the output end of the multi-section hydraulic rod 5 drives the test dummy 6 to be placed on the massage chair body 3 to simulate a person lying on the massage chair body 3. At this time, the massage chair body 3 is started to work, and multiple noise sensors 7 collect noise data of the massage chair body 3 in working condition. The collected noise values ​​are displayed intuitively on the display panel 8. By observing the values ​​of multiple noise sensors 7, the noise level can be understood, and the quietness test of the massage chair body 3 is completed.
