[0002] A seat armrest is an auxiliary device designed next to the seat, mainly used to provide support and help passengers maintain stability. It usually appears on the seats of cars, airplanes, trains, ships and other means of transportation. It can provide passengers with arm or elbow support during driving. The seat armrest can not only provide support and assistance, but also improve the comfort and convenience of the seat. Choose a suitable seat armrest according to actual needs and usage scenarios.

[0003] Deficiencies of the prior art: The seat armrests in the prior art are usually fixed to the seats, and during use, they need to occupy a certain space, which will limit the application scope or layout of the seats. In places with limited space, the armrests cannot be flipped to a position parallel to the seat back, and cannot form a more comfortable support surface. At the same time, they are fixed to the seat, which is inconvenient for cleaning and maintenance of the armrests and the inside of the seat. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The seat armrest with a flip function involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0020] The utility model provides a seat armrest with a flip function, such as Figure 1 and Figure 2 As shown, it includes an armrest body 1 and a mounting plate 2, a guide rod 3 is fixedly installed on one side of the top of the mounting plate 2, a first positioning block 4 is fixedly installed on the other side of the top of the mounting plate 2, a support plate 5 is fixedly connected to the front end of the mounting plate 2, the mounting plate 2 and the support plate 5 are partial structures of the seat, and a second positioning block 6 is fixedly connected to one side of the rear end of the support plate 5, a fixing rod 7 is fixedly connected to the bottom end of the armrest body 1, and the supporting strength of the armrest body 1 is increased by the fixing rod 7, a connecting assembly 8 is fixedly connected to the bottom end of the fixing rod 7, and the armrest body 1 is installed on the mounting plate 2 and the support plate 5 through the connecting assembly 8, a first rotating connecting block 9 is fixedly connected to the left end of the fixing rod 7, a rotating rod 10 is rotatably connected to the right end of the first rotating connecting block 9, and the end of the rotating rod 10 away from the first rotating connecting block 9 is rotatably connected to the second rotating connecting block 11.

[0021] Furthermore, one end of the second rotating connecting block 11 away from the rotating rod 10 is fixedly connected to the left end of the mounting plate 2, and the rotating rod 10 passes through and is rotatably connected to one side of the fixed rod 7. Through the rotation of the rotating rod 10, the armrest body 1 is driven to rotate upward and parallel to the seat. The guide rod 3 is set to a semi-arc shape, and one end of the guide rod 3 away from the mounting plate 2 is fixedly connected to one side of the rear end of the support plate 5. The accuracy of the rotation position of the armrest body 1 is ensured by the guide rod 3.

[0022] Further, such as Figure 3 The connecting component 8 includes a first connecting member 81, and a second connecting member 82 is fixedly connected to the right end of the first connecting member 81. The armrest body 1 is connected to the mounting plate 2 through the first connecting member 81 and the second connecting member 82. A positioning groove 83 is opened in the middle of the top of the second connecting member 82, and a sliding groove 84 is opened on the other side of the top of the second connecting member 82.

[0023] Further, such as Figure 4As shown, the second connecting member 82 is located at the top of the mounting plate 2, the shape and position of the positioning groove 83 are adapted to the shape and position of the first positioning block 4 and the second positioning block 6, and the positioning groove 83 is movably connected to the outer surfaces of the first positioning block 4 and the second positioning block 6. When the armrest body 1 is rotated upward, it is fixed to the outer surface of the second positioning block 6 through the positioning groove 83 to fix the position of the armrest body 1 to prevent the armrest body 1 from automatically rotating downward during use, and the stability of the armrest body 1 is ensured by the first positioning block 4 and the second positioning block 6.

[0024] Furthermore, the inner diameter of the slide groove 84 is adapted to the cross-sectional diameter of the guide rod 3, and the slide groove 84 is movably connected to the outer surface of the guide rod 3.

[0025] The working principle of the utility model is as follows: first, the armrest body 1 is installed on the mounting plate 2 through the connecting assembly 8. The mounting plate 2 and the supporting plate 5 are part of the seat structure. When in use, the rotating rod 10 rotates between the first rotating connecting block 9 and the second rotating connecting block 11, and the armrest body 1 is driven to rotate upward by the rotation of the rotating rod 10. When rotating upward, the armrest body 1 rotates upward along the outer surface of the guide rod 3 through the slide groove 84. The accuracy of the rotation position of the armrest body 1 is guaranteed by the guide rod 3. After rotating to be parallel to the seat, it is fixed to the outer surface of the second positioning block 6 through the positioning groove 83 on the surface of the second connecting piece 82, so that the position of the armrest body 1 is fixed to avoid the armrest body 1 automatically rotating downward during use. When the armrest body 1 is in place, the stability is increased by the first positioning block 4. The armrest body 1 is parallel to the seat back, so that the seat forms a more comfortable support surface. The fixed rod 7 at the bottom end of the armrest body 1 increases the supporting strength, and the seat armrest can be flipped according to the specific situation of the user.
