Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1-2, the rotating cup holder mechanism according to a preferred embodiment of the present invention comprises a frame assembly 1, a sliding assembly 2 and a driving mechanism 3, wherein, in the non-use state shown in fig. 1, the sliding assembly 2 is retracted inside the frame assembly 1, and the cup holder feature a is in a lying posture, i.e. the height of the cup body corresponds to a small armrest width, and the diameter of the cup body corresponds to an unlimited armrest height to fully utilize the height space. When the cup feature a needs to be used, the sliding assembly 2 firstly slides out of the frame assembly 1 under the action of the driving mechanism 3, and after the cup holder feature a passes over the head of the frame assembly 1, the cup holder feature a rotates with the lying posture as a starting point while continuously sliding out until the rotation 90 takes the standing posture, as shown in the use state of fig. 2.

As shown in fig. 3, the frame assembly 1 provides a rotation hole feature B1 and a slide slot feature C1, and as shown in fig. 4, the slide assembly 2 provides a rotation shaft feature B2 and a slide block feature C2. In the assembled state, the rotation shaft feature B2 is inserted into the rotation hole feature B1 to be engaged, and the slider feature C2 is inserted into the sliding groove feature C1 to be engaged, so as to limit the sliding and rotating motion of the sliding assembly 2 on the frame assembly 1.

Referring to fig. 3 and 5, the frame assembly 1 includes a mounting frame 11, an upper rotation guide block 12, a lower rotation guide block 13, and a cover plate 15, wherein the upper rotation guide block 12 and the lower rotation guide block 13 are fixed to the mounting frame 11 through the cover plate 15. In addition, the frame assembly 1 further comprises a locking mechanism 14 mounted on the mounting frame 11. As shown in fig. 3, the mounting frame 11 has a through hole extending forward and backward through the thickness of the frame for providing a sliding groove feature C1, the upper and lower

rotation guide blocks

12, 13 have through holes extending forward and backward through the length of the guide block for providing a rotation hole feature B1, and the locking mechanism 14 has a locking tongue 14a (see fig. 8 to 10) which is retractable in the up-down direction. As shown in fig. 5, the upper and lower

rotation guide blocks

lower guide grooves

12a,13a, respectively, which communicate with through holes penetrating the length of the guide blocks for providing the rotation hole feature B1, and the rear end of the cover plate 15 has a catching groove 15a. After the assembly of the frame assembly 1 is completed, the up-and-down

rotation guide blocks

12 and 13 and the body of the locking mechanism 14 cannot move relative to the mounting frame 11, and only the locking tongue 14a of the locking mechanism 14 can move up and down in the mounting frame 11.

Referring to fig. 4 and 5, the sliding assembly 2 includes a cup holder mounting seat 21, an upper clamp ring rotating member 22, a chassis rotating member 23, and a sliding frame 24, wherein the upper clamp ring rotating member 22 and the chassis rotating member 23 are fixed on the cup holder mounting seat 21 by the sliding frame 24 through hole-shaft fit. As shown in fig. 4, the carriage 24 has a projection for providing a slider feature C2. As shown in fig. 6, the upper clamp ring rotating member 22 includes an upper rotating rod 22a and an upper clamp ring 22b fixedly coupled together, wherein an upper guide protrusion 221 is fixed to a position adjacent to a rear end of the upper rotating rod 22 a. As shown in fig. 7, the chassis rotating member 23 includes a lower rotating rod 23a and a chassis 23b fixedly connected together, wherein a lower guide protrusion 231 is fixed to a position near the rear end of the lower rotating rod 23 a. After the assembly of the sliding assembly 2 is completed, the upper retainer ring rotary member 22 and the chassis rotary member 23 can only perform rotary motions about the respective rotary shafts (the upper rotary shaft 22a and the lower rotary shaft 23 a) in the fitting holes of the cup holder mounting seat 21. In conjunction with fig. 3 and 4, the carriage 24 provides a projection of the slider feature C2 to be inserted into a hole of the mounting frame 11 providing the chute feature C1, the upper rotary rod 22a of the upper clamp ring rotary member 22 and the lower rotary rod 23a of the chassis rotary member 23 provide the rotary shaft feature B2 and are inserted into through holes of the rotary hole features B1 provided by the upper and lower

rotary guide blocks

12, 13 to be engaged, and when the upper and lower

rotary rods

22a,23a are moved forward to a predetermined position, the upper and

lower guide bosses

221, 231 of the upper and lower

rotary rods

22a,23a enter the upper and

lower guide grooves

12a,13a of the upper and lower

rotary guide blocks

12, 13 to be moved to drive the rotation of the upper and lower

rotary rods

22a,23a, thereby rotating the upper clamp ring 22B and the chassis 23B.

As shown in fig. 5, the driving mechanism 3 includes a coil spring mounting seat 31 and a coil spring 32, wherein the coil spring mounting seat 31 is fixedly mounted at the tail ends of the upper clamping ring rotating member 22 and the chassis rotating member 23, one end of the coil spring 32 is fixedly connected to the coil spring mounting seat 31, and the other end is fixedly connected to the slot 15a of the cover plate 15.

The mechanism of the rotary cup holder mechanism of the present invention will be described in detail below.

In the opened state of the cup holder as shown in fig. 2, the front end of the sliding assembly 2 is pushed backward, and at this time, due to the cooperation between the upper and

lower guide protrusions

221, 231 of the upper and lower

rotary rods

22a,23a of the sliding assembly 2 and the upper and

lower guide grooves

12a,13a of the upper and lower rotary guide blocks 12, 13 of the frame assembly 1, the upper clamp ring rotary member 22 and the chassis rotary member 23 are rotated 90 degrees during the backward sliding of the sliding assembly 2, and the cup holder feature a gradually changes to the 90-degree folded state. Meanwhile, the coil spring mounting seat 31 moves backwards synchronously in the backward movement of the sliding assembly 2, and the coil spring 32 of the driving mechanism 3 is driven to be elongated under force. When pushing continues, the sliding assembly 2 contacts the inclined surface of the latch tongue 14a of the latch mechanism 14, as shown in fig. 8, so that the latch mechanism 14 starts to retract upwards until the latch state shown in fig. 9 is reached, and the latch is completed, and the rotating cup holder mechanism is in the non-use state shown in fig. 1. That is, the cup holder feature a is in the retracted state, the latch 14a of the latch mechanism 14 of the frame assembly 1 will block the column of the slide assembly 2, and the slide assembly 2 will not move although it is under the spring force of the coil spring 32. When the locking mechanism 14 is unlocked by external force, as shown in fig. 10, the latch tongue 14a is retracted upward and can no longer block the column of the sliding assembly 2, and at this time, the sliding assembly 2 starts to push the sliding assembly 2 to move forward as a whole under the action of the coil spring 32, as shown in fig. 8, when the upper and lower

rotary rods

22a,23a of the sliding assembly 2 slide to the position of matching with the upper and lower

rotary guide blocks

12, 13 of the frame assembly 1, due to the matching action of the upper and

lower guide protrusions

221, 231 of the upper and lower

rotary rods

22a,23a and the upper and

lower guide grooves

12a,13a, the upper and

lower guide protrusions

221, 231 of the upper and lower

rotary rods

22a,23a and the upper and lower

rotary guide blocks

12, 13 rotate the upper and lower clamping

ring rotary members

22, 23 by 90 degrees during the movement, and when sliding to the limit position, the cup holder characteristic a becomes the fully opened state, and the rotary cup holder mechanism is in the use state shown in fig. 2 again.
