[0030] Embodiment
[0031] The following is only the preferred embodiment of the utility model, the protection scope of the utility model is not only limited to the following examples, and belongs to the protection scope of the utility model for all technical solutions under the idea of the utility model.
[0032] Reference attached to the specification Figure 1-3 The utility model discloses a kind of anti-occupying seat mechanism and massage chair comprising the anti-occupying seat mechanism, contain backrest assembly 1, anti-occupying seat part support 2, anti-occupying seat iron frame 3, tension spring 4, leg assembly 5, bottom seat frame 6, backrest electric push rod 7 and anti-occupying seat electric push rod 8.
[0033] The left and right sides below the backrest assembly 1 are each provided with two rollers 11, and the rollers are slidably arranged in four slide rails (right first slide rail 61, right second slide rail 62, left first slide rail 63 and left second slide rail 64) on the bottom seat frame 6, wherein the right first slide rail 61 and the right second slide rail 62 are crossly arranged, and the left first slide rail 63 and the left second slide rail 64 are crossly arranged. The second drill hole 132 on the backrest assembly and the third push rod fixing seat 65 on the bottom seat frame 6 are respectively hingedly connected to one end of the backrest electric push rod 7. By controlling the extension of the backrest electric push rod 7, the left and right rollers 11 are driven to slide in the corresponding slide rails, so as to realize the lifting of the backrest assembly 1. The leg assembly 5 is hingedly connected to the leg rotating shaft 34 of the anti-occupying seat iron frame 3 through the leg rotating sheet 51. The bottom of the leg assembly 5 is pressed on the leg support pad 37, and the leg assembly 5 can rotate around the leg assembly rotating shaft B.
[0034] The backrest assembly is provided with an anti-occupying iron frame rotating shaft A. The anti-occupying iron frame rotating shaft A is provided with a rotating assembly 12, and the rotating assembly 12 can rotate around the anti-occupying iron frame rotating shaft A. The anti-occupying seat iron frame 3 is provided with a rotating assembly fixing hole 33. The anti-occupying seat iron frame 3 and the rotating assembly 12 are fixed by fasteners. The anti-occupying seat iron frame 3 is provided with a second push rod fixing seat 36. One end of the anti-occupying seat electric push rod 8 is hingedly connected to the second push rod fixing seat 36, and the other end is hingedly connected to the first drill hole 131 on the backrest assembly 1. Figure 2-4 By controlling the extension and contraction of the anti-seat-occupied seat electric push rod 8, the anti-seat-occupied seat iron frame 3 is driven to rotate around the anti-seat-occupied seat iron frame rotation axis A, thereby realizing the lifting and lowering of the anti-seat-occupied seat iron frame 3. The anti-seat-occupied seat support 2 is provided with a left first rotating member 22 and a right first rotating member 23, and a spring fixing hole 24 is provided at the connection with the anti-seat-occupied seat iron frame; the anti-seat-occupied seat iron frame 3 is provided with a left second rotating member 31 and a right second rotating member 32 corresponding to the left first rotating member 22 and the right first rotating member 23, and a spring fixing member 35 is provided corresponding to the spring fixing hole 24; the anti-seat seat support 2 and the anti-seat-occupied seat iron frame 3 are hinged between the left first rotating member 22 and the left second rotating member 31, and the right first rotating member 23 and the right second rotating member 32; one end of the tension spring 4 is fixed to the spring fixing hole 24, and the other end is fixed to the spring fixing member 35, and the anti-seat seat support 2 and the anti-seat-occupied seat iron frame 3 are flexibly connected through the tension spring 4.
[0035] Reference Manual Figure 2-5 When the massage chair is in standby mode, if someone sits on the anti-occupancy seat support 2, the pressure sensor 21 on the anti-occupancy seat support 2 will sense it and make the anti-occupancy seat electric push rod 8 extend, driving the anti-occupancy seat iron frame 3 and the anti-occupancy seat support 2 to rotate and lift around the anti-occupancy seat iron frame rotation axis A. See the attached manual. Figure 5 At this time, the leg support pad 37 is retracted, and the leg assembly 5 loses the support of the leg support pad 37 and is retracted under the action of gravity; making it impossible for people to sit on the leg assembly 5 and the anti-occupation seat support 2, thereby achieving the anti-occupation effect; when the pressure sensor 21 does not sense that someone is sitting on it, the anti-occupation seat electric push rod 8 will retract, and drive the anti-occupation seat iron frame 3 and the anti-occupation seat support 2 to rotate and lower around the anti-occupation seat iron frame rotation axis A. At this time, the leg support pad 37 is lifted, and the leg assembly 5 is on the leg support It is lifted up under the action of the support pad 37; when the anti-seat occupation iron frame descends, since the anti-seat occupation seat support 2 is longer and the contact surface is wider than the anti-seat occupation iron frame 3, the anti-seat occupation seat support 2 contacts the object before the anti-seat occupation iron frame 3. Furthermore, the anti-seat occupation seat support and the anti-seat occupation iron frame are hinged together and can rotate around the hinge point with each other. Therefore, when the seat support of the anti-seat occupation contacts an object, it will not continue to move downward with the anti-seat occupation iron frame, which can effectively prevent pinching injuries.
[0036] Reference Manual Figure 6-7 , which is another example of the present invention, the anti-occupation seat support member 2 and the anti-occupation seat iron frame 3 are connected by a hinged connection between the left first rotating member 22 and the left second rotating member 31 and the right first rotating member 23 and the right second rotating member 32 (therefore, this embodiment does not require a tension spring 4 to achieve a flexible connection between the anti-occupation seat support member 2 and the anti-occupation seat iron frame 3), refer to the appendix of the specification Figure 7 The right first rotating member 23 is provided with a limiting protrusion 231, and the corresponding right second rotating member 32 is provided with a limiting card 321. When the anti-occupation seat support 2 and the anti-occupation seat iron frame 3 rotate to a certain angle, the limiting protrusion 231 on the right first rotating member 23 will hit the limiting card 321 on the right second rotating member 32, causing the right first rotating member 23 to be unable to continue rotating in the same direction, thereby also preventing the anti-occupation seat support 2 from continuing to rotate upward, thereby realizing the rotation limitation of the anti-occupation seat support 2. The left first rotating member 22 and the left second rotating member 31 and the right first rotating member 23 and the right second rotating member 32 have the same setting method.
[0037] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
