Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a hidden cup holder assembly suitable for a seat armrest. Background Art

[0002] For commercial vehicles or vehicles with three rows of seats, such as seven-seater models, the independent seats in the second row are limited by space and for the sake of the aesthetics of the seats. The cup holder assembly is hidden in the armrest and is only extended from the armrest when a cup is needed. The cup holder assembly under this structure does not occupy the aisle space when not in use, so it is widely used in independent seats.

[0003] For example, the announcement number CN211280741U discloses a car armrest with a cup holder, in which the cup holder is arranged in the armrest through a motion mechanism, and the motion mechanism is also connected with a locking member, a locking guide sleeve, a spring and a protective sleeve. This part of the structure extends along the length direction of the armrest in the overall coordinated state. Therefore, for the armrest based on the disclosed technology, the overall space occupancy rate in the length direction of the armrest is relatively large. For some independent seats, it is also necessary to configure a flip table in the armrest, and for the seats used on both sides of the aisle, the size of the armrest is also limited. Therefore, when the cup holder assembly occupies a high space in the length direction of the armrest, it will directly affect the storage of the flip table, increasing the difficulty of designing the table.

[0004] Furthermore, for example, an armrest with a cup holder disclosed in the announcement number CN215126359U has a connecting seat disposed on the armrest body, the cup holder is rotatably disposed on the connecting seat, a support frame for preventing the cup from tipping over is movably disposed on the connecting seat, and the support frame is located above the cup holder. When in use, the cup is placed on the cup holder, and the support frame is located around the cup. Although the cup holder assembly under this structure no longer occupies the space in the length direction of the armrest, the connecting seat protrudes from the bottom of the armrest body. In this regard, the connecting seat will not interfere during normal use of the armrest, but when the armrest is not needed and the armrest is flipped relative to the seat to make the armrest in an upright state, the protruding connecting seat may cause collision and interference with the human body, so for the cup holder assembly under this structure, its hiding performance is still poor.

[0005] Therefore, for the cup holder assembly used in the armrest in the prior art, its structure needs to be further optimized in order to simultaneously take into account its concealment performance and reduce the occupancy rate inside the armrest. Utility Model Content

DETAILED DESCRIPTION

[0050] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0051] See also Figures 1 to 10As shown, the present embodiment provides a hidden cup holder assembly suitable for a seat armrest, and the seat may be an ordinary home seat or a car seat, and the present embodiment does not make an absolute limitation on this. Specifically, the hidden cup holder assembly adopted in the present embodiment includes: a cup holder shell and a cup holder rack used in conjunction with each other, wherein the cup holder shell is used to accommodate the cup holder rack when not in use, and the cup holder shell itself can be completely built into the seat armrest, and in this case, only an opening suitable for the cup holder rack to pop out needs to be opened at the side end of the armrest.

[0052] The cup holder shell used in this embodiment can be roughly a flat rectangular parallelepiped structure. From the perspective of the coordination between the seat armrest and the cup holder shell, the length direction of the cup holder shell extends along the length direction of the seat armrest. And the length space occupied by the cup holder shell in the length direction is very small relative to the length direction of the seat armrest. At this time, combined with the use of the car seat, the notch on the seat armrest only needs to be opened on the side end surface of the armrest facing the aisle. In this way, the use of the cup holder assembly in the use state will not affect the use of the seat itself. Although it will form a certain occupancy rate for the aisle space, when the cup holder assembly affects the passage of people or objects in the aisle, the cup holder assembly only needs to be stored in the seat armrest.

[0053] In order to enable the cup holder shell to meet the requirements of receiving and ejecting the cup holder, the cup holder shell includes a shell body 1 having a hollow receiving cavity 11, and an open opening communicating with the hollow receiving cavity 11 is formed on one end surface of the shell body 1; the cup holder is ejected relative to the cup holder shell through the open opening, and is also completely received in the hollow receiving cavity 11 through the open opening.

[0054] Next, the cup holder used in this embodiment is described in detail:

[0055] The cup holder includes a rotating seat 21 rotatably matched with the shell body 1, a first arc plate 22 formed on the rotating seat 21, a second arc plate 23 rotatably matched with the first arc plate 22, and a bottom support plate rotatably matched with the rotating seat 21; the first arc plate 22, the second arc plate 23 and the bottom support plate are suitable for enclosing and forming a receiving area 9 for accommodating the cup 3. The arc openings of the first arc plate 22 and the second arc plate 23 are arranged opposite to each other.

[0056] When the cup holder is received in the hollow receiving cavity 11, the bottom support plate flips toward the receiving area 9 and enters the receiving area 9, and the second curved plate 23 moves toward the first curved plate 22 to reduce the size of the receiving area 9 formed by the two. It should be noted that when the first curved plate 22 and the second curved plate 23 enclose the receiving area 9, the movable end of the second curved plate 23 does not directly contact the first curved plate 22, but there is a gap of a certain curvature, and the gap is smaller than the diameter of the cup 3 generally used, so that the cup 3 will not fall out of the gap.

[0057] Furthermore, the hollow accommodating chamber 11 includes a first accommodating chamber in the shape of a rectangular parallelepiped and a second accommodating chamber in the shape of an arc; the second accommodating chamber is connected to the first accommodating chamber; and the second arc plate 23 is suitable for being accommodated in the second accommodating chamber, and the rotating seat 21 and the bottom support plate are suitable for being accommodated in the first accommodating chamber.

[0058] Based on the above structure, this embodiment also has the following designs:

[0059] The second curved plate 23 is connected to the first curved plate 22 via a rotating shaft 26; and a first torsion spring 27 is sleeved on the rotating shaft 26 to realize the elastic connection between the second curved plate 23 and the first curved plate 22. A columnar matching cavity for matching the rotating shaft 26 is formed in the first curved plate 22, and the first torsion spring is built in the matching cavity, so that one end of the first torsion spring 27 is fixed in the matching cavity, and the other end of the first torsion spring 27 is connected to the second curved plate 23. Under this structure, when the second curved plate 23 is opened relative to the first curved plate 22 to form a placement for the cup 3, the first torsion spring 27 is in a slightly compressed state, so that the second curved plate 23 can form a certain pressure against the outer wall of the placed cup 3, and the cup 3 is clamped and limited between the first curved plate 22 and the second curved plate 23, thereby maintaining the stability of the cup 3 in the use state and preventing it from shaking with the driving of the vehicle. When the second curved plate 23 and the first curved plate 22 are relatively retracted to be accommodated in the hollow accommodating cavity 11, the first torsion spring 27 is further compressed and deformed, and the compression amplitude is greater than the state in which the first curved plate 22 and the second curved plate 23 are relatively opened. In this way, when the cup holder pops out of the cup holder shell, the elastic force of the first torsion spring 27 can help the second curved plate 23 to open relative to the first curved plate 22.

[0060] Furthermore, the bottom support plate used in this embodiment includes a base plate 24 rotatably matched with the rotating seat 21, and a supporting plate 25 matched with the base plate 24 in an L-shape; the supporting plate 25 is used to support the cup 3 from the bottom.

[0061] Based on the above situation, further, in order to enable the bottom support plate to be quickly deformed relative to the first arc-shaped plate 22 when the cup holder pops out from the cup holder shell, the base plate 24 of the present embodiment is connected to the rotating seat 21 via a rotating shaft 2826; and a second torsion spring 29 is sleeved on the rotating shaft 2826; and one end of the second torsion spring 29 abuts against the rotating seat 21, and the other end of the second torsion spring 29 abuts against the base plate 24.

[0062] In addition, in order to buffer the pop-up movement of the rotating frame relative to the shell body 1 and prevent the pop-up movement of the rotating frame from being too fast, a limit assembly is also provided between the rotating seat 21 and the cavity wall of the hollow accommodating cavity 11; in conjunction with the accompanying drawings, an optional implementation is given as an example, the limit assembly includes an arc-shaped rack 41 formed on the cavity wall of the hollow accommodating cavity 11, and a rotating gear 42 rotatably provided on the rotating seat 21 and meshing with the arc-shaped rack 41. The layout angle and curvature of the arc-shaped rack 41 here are consistent with the angle and curvature of the rotating seat 21 popping open relative to the shell body 1.

[0063] Finally, it should be noted that the cup holder accommodated in the shell body 1 needs to be locked by a locking assembly to prevent it from unexpectedly popping out of the cup holder shell.

[0064] Next, an example of a lock assembly is given with reference to the accompanying drawings:

[0065] Generally, the lock assembly includes a lock hook 51 rotatably disposed on the cavity wall of the hollow accommodating cavity 11, a clamp head 52 disposed on the lock hook 51, and a locking groove 61 disposed on the rotating seat 21 suitable for clamping with the clamp head 52; the groove wall of the locking groove 61 is provided with an inlet 62 suitable for the clamp head 52 to enter and an outlet 63 suitable for the clamp head 52 to leave. Under this structure, when the cup holder is to be stored in the cup holder shell, the clamp head 52 enters the locking groove 61 through the inlet 62, and when the cup holder is in the process of being ejected relative to the cup holder shell, the clamp head 52 leaves the locking groove 61 through the outlet 63.

[0066] In order to meet the above-mentioned usage requirements, the structures of the locking hook 51 and the locking groove 61 adopted in this embodiment are as follows:

[0067] First, the lock hook 51, whose end away from the locking groove 61 is rotatably matched with the shell body 1 through the connecting ear 53, and a recessed movable groove 55 for accommodating the lock hook 51 is provided in the cavity wall of the hollow accommodating cavity 11, and the lock hook 51 can swing around the connecting ear 53 in the movable groove 55, so that the clamping head 52 on the lock hook 51 can move in and out of the locking groove 61 with the movement of the lock hook 51. Here, the two side walls of the movable groove 55 along the depth direction of the hollow accommodating cavity 11 (the depth direction here specifically refers to the direction extending from the opening of the shell body 1 to its interior) form a limit on the swinging range of the lock hook 51.

[0068] Furthermore, taking a preferred embodiment as an example, the clamp head 52 is a cylindrical structure, which makes it easier to enter and exit the locking groove 61.

[0069] Secondly, the locking groove 61 includes a first push plate and a second push plate 72 which are spaced and arranged oppositely along the length direction of the locking hook 51 and are respectively used to push the clamping head 52. The first push plate is located between the second push plate 72 and the first arc-shaped plate 22; a first connecting plate 73 is provided between the end surfaces of the first push plate and the second push plate 72 on the same side, and a connecting plate 74 is also provided on the rotating seat 21; a second connecting plate 75 is also provided between the first push plate and the connecting plate 74; and an inlet 62 is formed between the first connecting plate 7373 and the first push plate and the second push plate 72, and an outlet 63 is formed between the second connecting plate 75 and the first push plate and the rotating seat 21; the first push plate, the second push plate 72, the connecting plate 74, the first connecting plate 7373 and the second connecting plate 75 together enclose the locking groove 61.

[0070] Based on the above situation, more specifically, the first push plate, the second push plate 72, the connecting plate 74, the first connecting plate 7373 and the second connecting plate 75 are all protruded on the same support wall surface of the rotating seat 21; and the protrusion heights of the first push plate, the second push plate 72 and the connecting plate 74 relative to the support wall surface are greater than the protrusion heights of the first connecting plate 7373 and the second connecting plate 75, so that the inlet 62 and the outlet 63 are both U-shaped.

[0071] In addition, it should be noted that the first push plate includes an L-shaped base plate 711 for connecting to the first connecting plate 7373, and an extension plate 712 connected to the second connecting plate 75; the base plate 711 and the extension plate 712 form an arc corner 713 on the wall surface facing the locking groove 61; and the base plate 711 is perpendicular to the first connecting plate 73, and the second connecting plate 75 is parallel to the base plate 711; the wall surface of the base plate 711 facing away from the locking groove 61 is an arc surface; an obtuse angle structure is formed between the wall surface of the second push plate 72 facing the locking groove 61 and the first connecting plate 73; the extension plate 712 is bent relative to the base plate 711 toward the locking groove 61 side, and a channel 76 suitable for the clamping head 52 to pass through is formed between the extension plate 712 and the connecting plate 74.

[0072] Based on the above situation, it should be noted that a rotating shaft 82 is provided between the shell body 1 and the rotating seat 21; the rotating shaft 82 is connected to one end of the rotating seat 21, so that the other end of the rotating seat 21 can drive the first arc plate 22, the second arc plate 23 and the bottom support plate to enter and exit the hollow accommodating cavity 11.

[0073] In more detail, a protruding connection column 81 is provided on the cavity wall of the hollow accommodating cavity 11 of the shell body 1, and a connection cavity suitable for inserting one end of a rotating shaft 82 is formed in the connection column 81. The rotating shaft 82 is connected to the rotating seat 21, so that the rotating seat 21 can achieve rotational cooperation with the connection cavity through the rotating shaft 82. Under this structure, in an optional case, a third torsion spring 83 is sleeved on the outer side of the connection column 81, and one end of the third torsion spring 83 is connected to the shell body 1, and the other end of the third torsion spring is connected to the rotating seat 21.

[0074] Based on the above-mentioned locking groove 61, locking hook 51 and third torsion spring 83, the use process of the cup holder of this embodiment to receive and eject the cup holder shell is as follows:

[0075] For example, the state in which the cup holder is completely accommodated in the hollow accommodating cavity 11 of the cup holder shell is the initial state, at which the clamp head 52 is located in the locking groove 61, and there is a gap between the side wall of the clamp head 52 and the arc corner 713 of the first push plate, and the side wall of the second arc plate 23 facing away from the first arc plate 22 and the cavity wall of the second accommodating cavity facing the first accommodating cavity, that is, the two do not directly abut against each other.

[0076] When it is necessary to pop the cup holder out of the hollow accommodating chamber 11 of the cup holder shell to place the cup 3, the end of the rotating seat 21 away from the rotating shaft 82 is pressed to make it move further toward the hollow accommodating chamber 11. At this time, the third torsion spring is gradually compressed, and the second push plate 72 gradually approaches the clamping head 52 until the second push plate 72 abuts against the outer side wall of the clamping head 52. Under the pushing action of the second push plate 72, the clamping head 52 moves along the second push plate 72 toward the wall surface of the locking groove 61 until the clamping head 52 moves into the channel 76 formed between the extension plate 712 and the connecting plate 74. At this time, both the first push plate and the second push plate 72 no longer form resistance to the movement toward the outlet 63. Based on this situation, the hand releases the pressure on the rotating seat 21, so that the rotating seat 21 moves away from the hollow accommodating cavity 11 under the action of the third torsion spring 83, and the clamping head 52 can finally separate from the locking groove 61 at the outlet 63 of the locking groove 61 through the above-mentioned channel 76. After the lock hook 51 separates from the locking groove 61, the rotating seat 21 drives the first curved plate 22, the second curved plate 23 and the bottom supporting plate to leave the hollow accommodating cavity 11, and after completely leaving the hollow accommodating cavity 11, the first curved plate 22, the second curved plate 23 and the bottom supporting plate enclose to form a receiving area 9 for accommodating the cup 3.

[0077] On the basis of the above situation, when the cup 3 is no longer needed and the cup holder is to be returned to the hollow accommodating chamber 11, the end of the rotating seat 21 away from the rotating shaft 82 is pressed to make it move further toward the hollow accommodating chamber 11. At this time, the third torsion spring is gradually compressed, the second arc plate 23 is retracted relative to the first arc plate 22, and the bottom support plate is also retracted into the receiving area 9 formed by the first arc plate 22 and the second arc plate 23. After the cup holder enters the hollow accommodating chamber 11, when the wall surface of the first push plate facing away from the locking groove 61 abuts against the clamping head 52 of the locking hook 51, as the rotating seat 21 is further pressed into the hollow accommodating chamber 11, the clamping head 52 moves along the first push plate under the action of the first push plate to the junction of the first connecting plate 73 and the wall surface of the base plate 711 facing the locking groove 61. In this regard, the hand releases the pressure on the rotating seat 21, so that the rotating seat 21 moves in the direction away from the hollow accommodating chamber 11 under the action of the third torsion spring 83. At this time, the base plate 711 produces a pressing effect on the wall of the locking groove 61 against the clamping head 52, so that when the first push plate moves with the rotating seat 21, the clamping head 52 is restricted by a side wall of the movable groove 55 along the depth direction of the hollow accommodating chamber 11, so that the clamping head 52 can only move gradually to the arc corner 713 of the first push plate through the entrance 62 under the pushing action of the base plate 711. In this regard, under the action of the clamping head 52 and the locking groove 61, the cup holder cannot leave the hollow accommodating chamber 11 without external force.
