DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 The present invention provides a technical solution: a seat armrest follow-up cup holder structure, comprising a seat frame 1, an armrest frame 2, a cup holder assembly 3 and a cable assembly 4. The seat frame 1 and the armrest frame 2 are connected to each other in a limited rotation manner, the cup holder assembly 3 and the cable assembly 4 are respectively arranged on the armrest frame 2, and the cup holder assembly 3 is arranged at the front end of the armrest frame 2.

[0025] See also Figure 2-Figure 3The cup holder assembly 3 includes a cup holder shell 31, a cup holder frame 32 and a cup holder base 33. The cup holder shell 31 is fixedly connected to the armrest frame 2. The cup holder frame 32 is limited and slides in the cup holder shell 31. An object is placed in the cup holder frame 32 and supported by the cup holder base 33. The cup holder base 33 is arranged at the bottom of the cup holder frame 32. The cup holder base 33 and the cup holder frame 32 are connected through a rotating shaft 34. A retaining torsion spring 35 is provided at the cup holder base 33. One end of the retaining torsion spring 35 abuts against the bottom of the cup holder base 33 and the other end abuts against the cup holder frame 32. The main body of the retaining torsion spring 35 is movably sleeved on the outer wall of the rotating shaft 34. The retaining torsion spring 35 makes the cup holder base 33 rotate toward the cup holder frame 32, that is, the cup holder base 33 is clamped toward the cup holder frame 32. With the axial direction of the rotating shaft 34 as the axis, a supporting surface 331 and a movable inclined surface 332 are respectively provided on both sides of the cup holder base 33, and the supporting surface 331 and the movable inclined surface 332 are integrally formed. The supporting surface 331 is provided at one end of the cup holder base 33 close to the cup holder frame 32, and the movable inclined surface 332 is provided at one end of the cup holder base 33 close to the cup holder housing 31, and the angle between the supporting surface 331 and the movable inclined surface 332 is an obtuse angle. The bottom of the cup holder frame 32 is provided with a limiting step 321 that abuts against the surface of the supporting surface 331, and the supporting surface 331 cannot go over the limiting step 321 to limit the rotation of the supporting surface 331.

[0026] The cup holder 32 is provided with a storage cavity 322 and a clamp. The storage cavity 322 is semi-open. One end of the clamp rotates with the cup holder 32. The clamp always keeps the object in the storage cavity 322 in a pre-tightened position. A limit protrusion is provided in the storage cavity 322, which always faces the center of the storage cavity 322. The limit protrusion is limited and rotates in the storage cavity 322. The limit protrusion can always limit the movement of the object in the storage cavity 322. The cavity wall of the storage cavity 322 is inclined so that the cup holder base 33 can adapt to the outer wall of the object when the opening angle between the cup holder 32 and the cup holder 32 is changed. A drive coil spring for driving the cup holder 32 to pop out, a damping for achieving stable pop-out of the cup holder 32, a labyrinth lock for achieving a locking relationship between the cup holder 32 and the cup holder shell 31, and an anti-escape spring for preventing the cup holder 32 from detaching from the cup holder shell 31 are provided between the cup holder 32 and the cup holder shell 31. The above are prior arts and will not be described in detail here.

[0027] The cable assembly 4 includes a long cable 41, a cup holder abutment 42 and a return spring 43. A vertically arranged active cavity 311 is provided at the front end of the cup holder shell 31. The return spring 43 and the cup holder abutment 42 are arranged in the active cavity 311. The cup holder abutment 42 is limitedly lifted and lowered in the active cavity 311. Narrowing openings are provided at the upper and lower ends of the active cavity 311 to prevent the cup holder abutment 42 from excessively lifting and lowering and thus detaching from the active cavity 311. One end of the return spring 43 is connected to the active cavity 311, and the other end is connected to the cup holder abutment 42. One end of the long cable 41 is fixedly connected to the seat frame 1 through a fixing member, and the other end is fixedly connected to the cup holder abutment 42. Since the long cable 41 has a certain length and the long cable 41 is always kept in a taut state, in order to prevent the path of the long cable 41 from being offset, the long cable 41 is limited by a plurality of limiting guide sleeves. The limiting guide sleeves are arranged on the armrest frame 2 and the cup holder housing 31, and the long cable 41 passes through the limiting guide sleeves. The long cable 41 converts the axial direction of the long cable 41 through the reversing wheel, and the reversing wheel can reduce the friction of the long cable 41 at the turning point and assist the movement of the long cable 41. Increasing the angle between the seat frame 1 and the armrest frame 2 can pull the long cable 41 and pull the cup holder abutment 42, and reducing the angle between the seat frame 1 and the armrest frame 2 can cause the elastic force of the return spring 43 to reset the cup holder abutment 42. The size of the middle portion of the cup holder abutting piece 42 is larger than the diameter of the narrowed opening, and the bottom end of the cup holder abutting piece 42 passes through the narrowed opening.

[0028] The bottom end of the cup holder abutment 42 is provided with a movable inclined surface 421, and a movable rod 333 is fixedly provided on the movable inclined surface 332. The movable rod 333 passes through the side wall of the cup holder 32 and abuts against the movable inclined surface 421. The side wall of the cup holder 32 is provided with a movable groove that allows the movable rod 333 to move inside. Since the lifting range of the cup holder abutment 42 is limited, the movable inclined surface 421 maintains a position that can abut against the movable rod 333. During the lifting and lowering process of the cup holder abutment 42, the movable rod 333 abuts against the movable inclined surface 421 at different points, thereby realizing the rotation of the movable rod 333 around the rotating shaft 34, and finally changing the angle between the supporting surface 331 and the cup holder 32. Since most of the outer wall of the movable rod 333 is a smooth surface, the movable rod 333 can reduce the friction during sliding when changing the abutment with the movable inclined surface 421 at different points, so that the whole process is carried out more stably.

[0029] In order to ensure that the supporting surface 331 maintains a uniform angle as a whole, in this embodiment, cup holder abutments 42 are respectively provided on both sides of the cup holder base 33, and one end of the long cable 41 connected to the cup holder abutment 42 is divided into two and respectively connected to the corresponding cup holder abutment 42.

[0030] When a heavy object is placed on the cup holder base 33 and the seat frame 1 is adjusted to a zero gravity posture, the cup holder base 33 will form a certain angle with the cup holder frame 32 . When no heavy object is placed on the cup holder base 33 , the cup holder base 33 will always remain close to the bottom of the cup holder frame 32 .

[0031] Working principle and use process of the present invention: please refer to Figure 4 When the seat frame 1 is in a normal state, the angle between the seat frame 1 and the armrest frame 2 is small, and the cup holder base 33 is clamped toward the cup holder frame 32. Figure 5 When the seat frame 1 is adjusted to a zero-gravity posture, the angle between the seat frame 1 and the armrest frame 2 increases, and the long cable 41 is pulled, thereby pulling the cup holder abutment 42, and the cup holder abutment 42 rises, thereby changing the abutment position of the cup holder abutment 42 and the movable rod 333. When the supporting surface 331 is subjected to pressure, the supporting surface 331 flips over, but because the cup holder abutment 42 abuts against the movable rod 333, the flipping angle of the supporting surface 331 is limited, and a certain angle is formed between the supporting surface 331 and the cup holder 32, so that when the seat frame 1 is adjusted to a zero-gravity posture, the cup holder base 33 cooperates to complete a certain tilt to prevent the cup body filled with liquid placed on the cup holder base 33 from spilling.

[0032] When the cup holder 32 is empty, the passenger adjusts the seat to a zero-gravity posture, and after the cup holder 32 is ejected, the cup holder base 33 is clamped toward the cup holder 32 under the preload force of the torsion spring 35. When an object is placed in the cup holder 32, the cup holder base 33 is opened by gravity, but the opening angle of the cup holder base 33 is limited by the cup holder abutment 42. When the passenger adjusts the seat back to a normal posture from the zero-gravity posture, the cup holder abutment 42 descends due to the reset spring 43 and pushes the movable rod 333 toward the cup holder housing 31, and the cup holder base 33 is reset together with the action of the torsion spring 35.

[0033] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
