[0002] A "seat" refers to furniture or tools used for sitting, lying, resting, or supporting the human body, with a wide variety of types, covering different functions, materials, and design styles.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

The lifting detection mechanism 3, the front-back detection mechanism 4, the tilting detection mechanism 5, the left-right detection mechanism 6 and the rotation detection mechanism 7 are all arranged on the upper surface of the stainless steel plate 2. The stainless steel plate 2 is fixedly installed on the upper surface of the detection table 1 by bolts, and a plurality of uniformly distributed positioning holes are formed in the stainless steel plate 2;

[0034] The lifting detection mechanism 3 is used to test the ascending or descending function of the armrest main body 8, the front-back detection mechanism 4 is used to test the front-back moving function of the armrest main body 8, the tilting detection mechanism 5 is used to test the front-end and rear-end up-and-down tilting function of the armrest main body 8, the left-right detection mechanism 6 is used to test the left-right moving function of the armrest main body 8, and the rotation detection mechanism 7 is used to test the left-right rotation function of the armrest main body 8.

[0035] In this embodiment, the armrest main body 8 is composed of a footrest located at the bottom, a guide rail fixedly installed on the upper surface of the footrest, a sliding sleeve slidably matched with the guide rail, an armrest surface movably installed at the top of the sliding sleeve, an adjusting dial movably installed on the sliding sleeve, and a support plate inserted and installed inside the footrest.

[0036] Embodiment 2:

[0037] This embodiment provides a multifunctional armrest detection device. In addition to including the technical solutions of the above embodiment, it also has the following technical features. The lifting detection mechanism 3 includes:

[0038] A vertical electric cylinder 9, which is fixedly installed on the upper surface of the stainless steel plate 2. The top of the telescopic rod of the vertical electric cylinder 9 is fixed with a limit clip 10 having a C-shaped cross-section. A support arm 1 is fixedly installed on the upper surface of the stainless steel plate 2 around the vertical electric cylinder 9. A fixed block 12 is fixedly installed on the support arm 1. The footrest of the armrest main body 8 is fixedly installed on the fixed block 12, and one end of the armrest surface of the armrest main body 8 is arranged in the inner cavity of the limit clip 10.

[0039] Among them, when it is necessary to detect the rising or falling function of the armrest main body 8, unlock the adjusting paddle on the armrest main body 8 so that the sliding sleeve on the armrest main body 8 can move freely on the guide rail. At this time, start the vertical electric cylinder 9. The telescopic rod of the vertical electric cylinder 9 drives the limit clip 10 to move up and down. The limit clip 10 rises through the fixed force value of the vertical electric cylinder 9 and reaches the specified position. During this process, the inner side surface of the lower end of the limit clip 10 contacts the lower surface of the armrest surface of the armrest main body 8 and drives the upper half of the armrest main body 8 to move upward, thereby completing the detection of the rising function of the armrest main body 8. Start the vertical electric cylinder 9 again. The fixed force value of the vertical electric cylinder 9 moves downward and drives the limit clip 10 to move downward. At this time, the inner side surface of the upper end of the limit clip 10 drives the upper surface of the armrest surface of the armrest main body 8 to move downward, thereby completing the detection of the falling function of the armrest main body 8. The above steps can be tested through cyclic fatigue to completely obtain the specific actual situation of the up and down lifting function of the armrest main body 8, making the data more accurate.

[0040] By setting up the lifting detection mechanism 3, the rising or falling function of the armrest main body 8 can be fully and effectively detected, greatly saving labor and improving the detection efficiency.

At this time, start the horizontal electric cylinder 14. The telescopic rod of the horizontal electric cylinder 14 is displaced forward or backward with a fixed force value, which can drive the first pulling plate 15 to displace synchronously. The first pulling plate 15 drives the armrest surface of the armrest main body 8 to perform back-and-forth tests.
