[0031] The present application is described in detail below through specific embodiments:

[0032] The storage sofa armrest of the embodiment of the present application is as follows Figure 1-4 As shown, it includes an armrest body 10, an armrest cover 20 and a limit member 30. The armrest body 10 is provided with a receiving groove 11 with a side opening, and the notch of the receiving groove 11 is provided with a first stop member 12. The armrest cover 20 is arranged at the bottom of the notch of the receiving groove 11 and is rotatably connected. A storage box 21 is provided on the surface of the armrest cover 20 facing the receiving groove 11. A second stop member 22 is provided on the armrest cover 20. The armrest cover 20 can open or close the notch of the receiving groove 11. The limit member 30 is movably assembled on the armrest cover 20. The limit member 30 includes a first limit portion 31 and a second limit portion 32. When the armrest cover 20 is rotated to a first opening angle, the second stop member 22 and the second limit portion 32 abut. When the armrest cover 20 is rotated to a second opening angle, the first limit portion 31 abuts against the first stop member 12, so that the armrest cover 20 is maintained at the second opening angle, and the second opening angle is greater than the first opening angle.

[0033] The storage sofa armrest provided in the embodiment of the present application is, firstly, Figure 1 As shown, when the armrest cover 20 is in the closed state, the storage box 21 and the limiting member 30 are in the receiving groove 11, as shown in FIG. Figure 2 As shown, when the armrest cover 20 rotates from the closed state to the first open angle, the second stopper 22 abuts against the second limiting portion 32, so that the second stopper 22 can drive the limiting member 30 to move, as shown in FIG. Figure 3As shown, when the armrest cover 20 is then rotated from the first opening angle to the second opening angle, the first limiting portion 31 and the first stop member 12 abut against each other, so that the limiting member 30 is fixed relative to the armrest body 10, thereby maintaining the armrest cover 20 at the second opening angle. Due to the action of the limiting member 30, the armrest cover 20 can be maintained in an open state at a larger unfolding angle, which is convenient for storing and retrieving larger objects, providing convenience and a better experience for the user.

[0034] In this embodiment, the limit member 30 is assembled on the armrest cover 20 through the active connection structure 40. Since the armrest cover 20 is always rotatably connected at the bottom of the slot of the accommodating slot 11, the limit member 30 needs to undergo a certain displacement change with the armrest cover 20 during the movement of the armrest cover 20, and then rotate with the armrest cover 20. This is to ensure that the armrest cover 20 remains in an open state at a larger angle. Therefore, the connection between the armrest cover 20 and the limit member 30 requires both a certain displacement and relative rotation during the rotation of the armrest cover 20. The active connection structure 40 is configured as During the process of rotating the armrest cover 20 from the closed position to the first opening angle, the movable connection structure 40 can make the limit member 30 and the armrest cover 20 move relative to each other so that the second stop member 22 and the second limit portion 32 abut against each other, thereby the second stop member 22 can drive the limit member 30 to move, and during the process of rotating the armrest cover 20 from the first opening angle to the second opening angle, the movable connection structure 40 can make the limit member 30 and the armrest cover 20 rotate synchronously so that the first limit portion 31 and the first stop member 12 abut against each other, at this time, the limit member 30 is fixed relative to the armrest body 10, thereby keeping the armrest cover 20 at the second opening angle.

[0035] Specifically, the movable connection structure 40 includes a first hinge 41, a slide rail and a slider. The first hinge 41 is rotatably connected to the first rotating plate and the second rotating plate. The first rotating plate is assembled on the armrest cover 20. The rotation axis of the first hinge 41 is parallel to the rotation axis of the armrest cover 20, ensuring that it can rotate synchronously with the armrest cover 20. The slider is arranged on the second rotating plate of the first hinge 41, and the slide rail is arranged on the limit member 30. The slide rail and the slider are slidably matched. The length direction of the slide rail is parallel to the length direction of the armrest cover 20. Corresponding to the rotation direction, when the armrest cover 20 rotates from the closed state to the first open angle, the limit member 30 and the armrest cover 20 are in a relative motion state, and the first hinge 41 rotates with the armrest cover 20, so that the slider slides relatively on the slide rail to generate a displacement difference between the limit member 30 and the armrest cover 20, and the second stop member 22 abuts against the second limit portion 32 when the armrest cover 20 rotates to the first open angle. At this time, the second stop member 22 can drive the limit member 30 to rotate synchronously.

[0036] When the armrest cover 20 rotates from the first opening angle to the second opening angle, the limiting member 30 rotates synchronously with the armrest cover 20 until the first limiting portion 31 abuts against the first stopper 12, so that the limiting member 30 and the armrest body 10 are in a relatively fixed state. At this time, the second stopper 22 abuts against the second limiting portion 32 to restrict the armrest cover 20 from continuing to rotate, so that the armrest cover 20 can be maintained at the second opening angle. The displacement difference between the armrest cover 20 and the limiting member 30 allows the second opening angle to be relatively large. The large opening angle makes it convenient to store and retrieve larger objects. Through the design of the first hinge 41, the slide rail and the slider, the armrest cover 20 can not only realize its own rotation during the rotation process, but also does not hinder the synchronous rotation of the limit member 30. The relative displacement is generated through the cooperation of the slider and the slide rail, which provides more possibilities and adaptability for the movement between the limit member 30 and the armrest cover 20, so that the limit member 30 can not only realize the limiting effect on the armrest cover 20, but also generate a relative displacement difference with the armrest cover 20.

[0037] Furthermore, if Figure 3 As shown, through the cooperation between the first stopper 12 and the first limiting portion 31, the movement range of the limiting portion 30 when following the rotation of the armrest cover 20 can be accurately limited, so that the armrest cover 20 is maintained at the second opening angle. Specifically, the first stopper 12 is arranged at the upper edge of the notch of the receiving groove 11, and at least a portion of the first limiting portion 31 extends between the first stopper 12 and the bottom of the receiving groove 11. The first stopper 12 can limit the first limiting portion 31 from the top of the receiving groove 11 to escape from the receiving groove 11. In this way, a stable support can be provided in the vertical direction, so that the stability of the limiting portion 30 is better when limiting, so as to ensure that the armrest cover 20 has good stability when opening to the second opening angle. Of course, in another embodiment, the first stopper 12 can also be arranged at the edges of the two sides of the notch of the receiving groove 11, and at least a portion of the first limiting portion 31 extends between the first stopper 12 and the bottom of the receiving groove 11.

[0038] Specifically, the first stop member 12 is a stop bar extending along the upper edge of the slot of the receiving slot 11, and the first limiting portion 31 is a limiting plate corresponding to the length of the stop bar. The stopping effect is achieved by the fit between the limiting plate and the stop bar. The contact area between the limiting plate and the stop bar is large, and the fit is tighter, which can improve the stability of the overall structure, making the armrest cover 20 more reliable and stable at the second opening angle. After the limiting plate and the stop bar are fitted together, the top of the receiving slot 11 is sealed to prevent objects or dust from entering the receiving slot 11.

[0039] In this embodiment, the storage box 21 includes a first side wall 211 and a second side wall 212 that are arranged opposite to each other. The second stopper 22 is arranged on the first side wall 211. The first side wall 211 provides reliable support for the second stopper 22. The second limiting portion 32 is arranged close to the first side wall 211. At least a portion of the second limiting portion 32 extends between the second stopper 22 and the armrest cover 20, so that the second limiting portion 32 can move between the second stopper 22 and the armrest cover 20, so that the limiting portion 30 will not separate from the storage box. The object box 21 ensures reliable and stable limiting. When the armrest cover 20 is in a closed state, the second limiting portion 32 of the limiting member 30 is close to the armrest cover 20. When the armrest cover 20 rotates from a closed state to a first open angle, the armrest cover 20 and the limiting member 30 move relative to each other. The second limiting portion 32 of the limiting member 30 moves toward the position of the second stop member 22 to achieve abutment with the second stop member 22. Therefore, when the armrest cover 20 continues to rotate, the second stop member 22 can drive the limiting member 30 to rotate synchronously.

[0040] Furthermore, a third stopper is provided on the second side wall 212, and the limiting member 30 also includes a third limiting portion, which is arranged close to the second side wall 212, and at least a portion of the third limiting portion extends between the third stopper and the armrest cover 20. The third limiting portion and the second limiting portion 32 are two side plates arranged relatively to each other, and the two side plates are respectively connected to the first limiting portion 31. In this way, the limiting member 30 is limited by two relatively arranged parts to enhance the limiting stability, so that the armrest cover 20 can drive the limiting member 30 to move more reliably during the rotation process, and the overall structure is more stable, thereby reducing the shaking or displacement of the object in the limiting position, enhancing the limiting effect, and limiting in multiple directions can also provide limiting accuracy.

[0041] In this embodiment, Figure 4 As shown, the storage box 21 also includes a third side wall 213, a fourth side wall 214 and a bottom wall. The third side wall 213 and the fourth side wall 214 are arranged relatively to each other. The fourth side wall 214 is fixed on the armrest cover 20, so that the storage box 21 is disposed on the armrest cover 20 and is fixed to the armrest cover 20 through the fourth side wall 214. In this way, the structural strength of the storage box 21 is higher, and heavier items can be placed thereon better. It is more reliable during long-term use and is easy to install and disassemble as a whole. The first side wall 211, the second side wall 212, the third side wall 213, the fourth side wall 214 and the bottom wall form a storage space with an opening facing upward for placing stored items. The structure is simple and easy to use.

[0042] In order to arrange the storage space reasonably, increase the utilization rate of the space, and realize the diversification of storage functions, a partition 215 is provided in the storage space. The partition in this embodiment is parallel to the first side wall 211. Of course, in other embodiments, the partition 215 can also be perpendicular to the first side wall 211, which is not limited here. The partition can divide the storage space into different areas, which is convenient for the classification and placement of different items, making the items more orderly, improving the effective use of space, and allowing users to find the required items more quickly, thereby improving the convenience of use. The partition 215 can also enhance the overall structural strength of the storage box 21 to a certain extent, making it more sturdy and durable. In this way, different categories of items can be separated, providing privacy protection for certain items to a certain extent.

[0043] Specifically, the armrest cover 20 is rotatably connected to the bottom of the slot of the accommodating slot 11 through the second hinge 50. The rotatable connection is achieved through the second hinge 50, so that the structure between the armrest cover 20 and the accommodating slot 11 is compact. When not in use, the armrest cover 20 can be attached to the bottom of the slot without occupying additional external space, thereby maintaining the compactness of the overall layout. By rotating to open and close, it is more convenient and natural to use. The user can easily open and close the armrest cover 20, and there will be no protruding connection structure that affects the overall aesthetics, making the product appearance more simple and elegant, and it is relatively more stable during the rotation process, and is not prone to shaking or deviation.

[0044] When the storage sofa armrest of this embodiment is in use, first, when the armrest cover 20 is in the closed state, the storage box 21 and the limiting member 30 are in the accommodating groove 11, and the armrest cover 20 is pulled. When the armrest cover 20 is rotated from the closed state to the first open angle, the second stop member 22 abuts against the second limiting portion 32, so that the second stop member 22 can drive the limiting member 30 to move. Continue to pull the armrest cover 20, when the armrest cover 20 is rotated from the first open angle to the second open angle, the first limiting portion 31 abuts against the first stop member 12, so that the limiting member 30 is fixed relative to the armrest body 10, thereby maintaining the armrest cover 20 at the second open angle. Due to the action of the limiting member 30, the armrest cover 20 can be maintained in the open state at a larger unfolding angle, which is convenient for storing and retrieving larger objects, providing convenience and a better experience for users.

Therefore, the sofa in this embodiment has substantially the same technical effect as the above-mentioned storage sofa armrest. Since the technical effect of the storage sofa armrest has been fully explained, it will not be repeated here.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
