As shown in Figures 1, 2, 3, 7, 8, 9, and 10: a seat folding armrest cup holder, including a telescopic box 1, a mounting base box 2 and a folding mechanism 3, the mounting base box 2 is movably provided with Telescopic box 1, a folding mechanism 3 is movably arranged between the installation base box 2 and the telescopic box 1;

The folding mechanism 3 is composed of the folding components on the left and right sides, the folding movable frame 35, the cup holder panel 31, and the cup bottom connecting piece 12 axially connected to each other;

The folding components on the left and right sides each include a front and rear upper folding bar 37 and a front and rear lower folding bar 38, and the front and rear upper folding bars 37 and the front and rear lower folding bars 38 on the left and right sides are pivotally connected to each other by the folding movable frame 35;

The upper ends of the left and right folding components are pivotally connected to the bottom of the left and right sides of the cup holder panel 31, and the lower ends of the left and right folding components are pivotally connected to the left and right sides of the cup bottom connector 12 respectively;

An upper parallelogram is formed between the cup holder panel 31, the folding movable frame 35 and the pivot points of the front and rear upper folding bars 37;

A lower parallelogram is formed between the folding movable frame 35, the cup bottom connecting piece 12 and the axial joints of the front and rear lower folding bars 38;

The left and right sides of the front end of the cup holder panel 31 are respectively fixedly provided with a front limit sliding shaft 32, and the rear end of the folding movable frame 35 is fixedly connected with a folding movable sliding shaft 36.

As shown in Figures 2, 4, 5, 7: the left and right sides of the front end of the telescopic box 1 are respectively provided with front folding limit chutes 11, and the front limit sliding shaft 32 can slide up and down in the front folding limit chutes 11; The left and right sides of the mounting base box 2 are respectively provided with rear-folding limit chute 21, and the folding and moving sliding shaft 36 can slide in the rear-folding limit chute 21; the cup bottom connector 12 is fixed to the bottom of the telescopic box 1.

As shown in FIGS. 2, 4, 6, and 10, the length of the lower folding strip 38 is longer than the length of the upper folding strip 37. The advantage of this technical design is that when the folding mechanism 3 is folded, the cup holder panel 31 at the upper end can gradually move forward. Because the front end of the telescopic box 1 is an arc-shaped panel with the upper end backward and the lower end forward, it is beneficial to During the folding process, the rear end of the cup holder panel 31 touches the upper front part of the mounting base box 2. Second, the folded front part of the folding mechanism 3 can be hidden in the arc-shaped panel at the front end of the telescopic box 1. This design can make the exposed volume of the telescopic box 1 at the front end of the foldable armrest and the upper end of the installation base box 2 smaller, so that the foldable armrest has more space to install more soft cushions, making the foldable armrest more comfortable ; The lower folding strip 38 is slightly curved to avoid the folding and moving sliding shaft 36 when the folding mechanism 3 is completely folded. A tension spring can also be installed at the joint between the upper folding bar 37 and the lower folding bar 38. The tension spring always expands the outer ends of the upper folding bar 37 and the lower folding bar 38 outwards, so that the armrest cup holder can be integrated. The occurrence of noise can be avoided when the vehicle is running, and the cup holder panel 31 can also withstand greater pressure.

The front folding limit chute 11 is set with a slightly inclined arc and the rear folding limit chute 21 is connected vertically, inclined and horizontally. When the telescopic box 1 is manually pushed back, it is connected to the lower end of the lower folding bar 38 The cup bottom connector 12 that is pivotally connected also moves backward at the same time, and at this time, the folding and moving sliding shaft 36 at the rear end of the folding movable frame 35 pivotally connected to the upper end of the lower folding bar 38 and the lower end of the upper folding bar 37 is limited to the rear In the vertical area of the folding limit chute 21, when the telescopic box 1 is pushed backward, the lower parallelogram is centered on the pivot point of the lower end of the lower folding bar 38, the length of the lower folding bar 38 is the radius, and the folding movable frame 35 is opposite Turn the ground forward and down to fold, and at the same time descend. The front limit sliding shaft 32 at the front end of the cup holder panel 31 pivotally connected to the upper end of the upper folding bar 37 will also fold downwards under the restriction of the front folding limit chute 11, because the front folding limit chute 11 is slightly inclined Therefore, at the beginning of folding, the folding speed of the upper folding strip 37 is relatively slower than that of the lower folding strip 38. When the telescopic box 1 is manually pushed back into the installation base box 2, the folding mechanism 3 begins to fold, and the spring 18 also accumulates energy. When the telescopic box 1 is completely entered into the installation base box 2, the locking mechanism will lock the telescopic box 1 When needed, press the lock button 5 to unlock, the telescopic box 1 automatically stretches, and the folding mechanism 3 also stretches accordingly. This folding structure is similar to the structure of the quadrilateral zooming ruler, which can make the folding mechanism 3 smoother. The arc slope of the front folding limit chute 11 is matched with the length ratio of the upper folding bar 37 and the lower folding bar 38, and the front limit sliding shaft 32 after the folding mechanism 3 is folded is just in the curved front folding limit sliding The bottom of the groove 11; and the rear fold limit chute 21 is connected vertically, inclined and horizontally: the vertical setting at the upper end can quickly fold the folding mechanism 3, so that the cup holder panel 31 quickly drops, so that its front and rear sides will not It hits the upper rear side of the telescopic box 1 and the upper front side of the mounting base box 2. Because when the folding mechanism 3 is stretched and used, the upper, middle, and lower axis joints of the upper folding bar 37 and the lower folding bar 38 are in a vertical state. At this time, the folding movable sliding axis 36 at the rear end of the folding movable frame 35 only needs to be gently pushed forward. That is to say, quick folding can be realized (also when the telescopic box 1 is pushed back and retracted, the sliding shaft 36 is relatively formed to move forwards). After the folding mechanism 3 is folded to a relative height, the front side angle between the lower folding bar 38 and the cup bottom connector 12 is getting smaller and smaller, as shown in FIGS. 3 and 4, the folding movement of the rear end of the folding movable frame 35 The sliding shaft 36 enters the inclined area of the rear folding limit chute 21. At this time, the angle of the inclined area is similar to the front angle between the lower folding bar 38 and the cup bottom connector 12, which is conducive to the smoothness of folding; After the mechanism 3 is completely folded, the folding and moving sliding shaft 36 at the rear end of the folding and moving frame 35 enters the horizontal area, and the telescopic box 1 can be completely retracted into the installation base box 2 at this time. Otherwise, stretch.

Play the role of resistance to smooth rotation. The rotary damper 16 can only be finally installed and fixed from the damper installation hole 25 after the telescopic box 1 enters the installation base box 2.

As shown in Figures 6 and 11: the spring spring 18 includes a traction spring bar and a mounting shell. A mounting shaft is fixed in the mounting shell. The inner end of the traction spring bar is fixed on the mounting shaft, and the outer end of the traction spring bar is fixed. In the spring bar buckle groove 19 at the bottom front end of the installation base box 2, the spring spring 18 always ejects the telescopic box 1 from the installation base box 2 forward. The spring 18 is a simple and effective energy storage device that stores energy when the telescopic box 1 is pushed back and retracted, so that the telescopic box 1 can be automatically ejected from the mounting base box 2, and is buffered by the rotary damper 16. Stretch forward gently under the action.

As shown in Figures 8, 9, and 11: the left and right outer sides of the bottom of the telescopic box 1 are fixedly provided with telescopic sliding strips 13, and the left and right inner sides of the mounting base box 2 are respectively provided with telescopic sliding strips 13 corresponding to the telescopic sliding strips 13 13 coincides with the telescopic chute 23.

The locking mechanism is an existing technology, and there are many types of this technology, and the present invention will not be elaborated and limited too much.

As shown in Figure 7: the cup holder panel 31 is provided with a cup limit opening, and the cup holder panel 31 around the cup limit opening is movably provided with a plurality of cup clamping members 6; the cup bottom connector 12 is in position with the cup Cup grooves are arranged at the vertical concentric part of the mouth. The cup clamping member 6 is arranged to relatively fix the water cup. The cup clamping member 6 is movably pivotally connected to the cup holder panel 31, and a spring is arranged at the axial connection, and the spring always springs the cup clamping member 6 to a horizontal shape. That is, when the water cup is placed, the cup clamping member 6 always springs toward the center of the limit opening of the cup, and the water cup can be relatively fixed.

As shown in Figure 12, a wrench buckle 7 is provided on the lower side of the front end of the telescopic box 1. The setting of the wrench buckle 7 can be used when the folding armrest is folded up and down after the telescopic box 1 is folded and retracted.
