[0035] The technical solution of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please refer to Figures 1 to 12 This utility model provides a sofa armrest rotating and flattening structure.

[0037] like Figure 1 As shown, the sofa armrest rotating and flat structure includes two sofa seats 1 placed horizontally side by side, a backrest 2 installed at the rear of the sofa seats 1, and sofa armrests 3 installed on both sides of the sofa seats 1.

[0038] In this embodiment, the sofa armrest 3 includes a first sofa armrest 31 installed on one side of the sofa seat 1 and a second sofa armrest 32 installed on the other side of the sofa seat 1; the first sofa armrest 31 is connected to the sofa seat 1 through an armrest rotation mechanism 4; the first sofa armrest 31 is manually driven to rotate 180 degrees along the connecting surface through the armrest rotation mechanism 4, and after rotation, the vertical surface of the outer side of the sofa armrest 3 is parallel to the upper surface of the sofa seat 1; the first sofa armrest 31 is laid flat, serving as part of the bed, increasing the length space for lying down, and improving the comfort of using it as a bed within a limited space.

[0039] Similarly, the second sofa armrest 32 can also rotate independently; furthermore, in other embodiments, both the first sofa armrest 31 and the second sofa armrest 32 can rotate.

[0040] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the first sofa armrest 31 is provided with a horizontally arranged first receiving groove 51, and a T-shaped tabletop 8 is inserted inside the first receiving groove 51. The T-shaped tabletop 8 includes an insertion part inserted into the first receiving groove 51 and a table surface 82 mounted on the upper part of the sofa armrest 3. The table surface 82 is used to place beverages and portable electronic devices, so that customers can relax and work briefly on the sofa. Furthermore, the insertion part slides horizontally along the inside of the first receiving groove 51, thereby adjusting the horizontal position of the table surface 82 on the sofa armrest 3.

[0041] Furthermore, such as Figure 3 As shown, the second sofa armrest 32 is provided with a second horizontally arranged receiving groove 52, and the backrest 2 is provided with a third vertically arranged receiving groove 53. Several T-shaped tabletops 8 are inserted into both the second receiving groove 52 and the third receiving groove 53.

[0042] like Figure 3 As shown, the second receiving groove 52 and the third receiving groove 53 are interconnected, so that the T-shaped platform 8 can be manually pulled out from the second receiving groove 52 and then inserted into the third receiving groove 53.

[0043] This allows the T-shaped tabletop 8 to be manually adjusted to a suitable position, enabling beverages and portable electronic devices to be placed in any location.

[0044] In this embodiment, the third receiving groove 53 and the first receiving groove 51 are not connected. The T-shaped platform 8 can be manually pulled out from the first receiving groove 51 and then inserted into the third receiving groove 53.

[0045] In other embodiments, the adjustment surface 82 consists of two parts connected by several connecting hinges. One end of the adjustment surface 82 is folded to the other end of the adjustment surface 82 via the connecting hinges, thus facilitating unfolding and retraction. When space permits, unfolding provides a larger support range, allowing for the placement of more beverages; when space is limited, retraction enables basic functionality.

[0046] In other embodiments, the adjustment platform 82 can also rotate around the insertion part to adjust the direction and position of the platform 82, so that the platform 82 rotates around the insertion part and is limited by a spring protrusion at 90° to maintain a stable position.

[0047] like Figure 3 As shown, the adjustment platform surface 82 is square or circular.

[0048] like Figure 4 As shown, the connecting surface of the first sofa armrest 31 is inclined at 45 degrees to the connecting surface of the sofa seat 1; a number of sofa legs 6 are fixedly connected to the bottom of the sofa seat 1.

[0049] like Figure 7 As shown, the armrest rotation mechanism 4 includes an armrest turntable 41 installed at the bottom of the first sofa armrest 31 and a fixed seat 42 installed on the sofa seat 1. The armrest turntable 41 and the fixed seat 42 are rotatably connected by a rotating shaft 43; the armrest turntable 41 rotates around the rotating shaft 43.

[0050] Furthermore, such as Figure 8 As shown, the armrest turntable 41 is provided with slots 44 on both sides, and a limiting plate 45 is installed on the fixing base 42. There are two slots 44, which are symmetrically arranged. The limiting plate 45 is located on one side of one of the slots 44. The armrest turntable 41 is engaged with the limiting plate 45 through the slots 44 to limit and fix the armrest turntable 41. This achieves the limiting after 180-degree rotation and realizes stable two-speed rotation.

[0051] Furthermore, such as Figure 8 As shown, in order to achieve stable positioning, the bayonet 44 is a U-shaped bayonet that is inserted into the limiting plate 45.

[0052] In order to pull the latch 44 laterally out from inside the limiting plate 45, in this embodiment, a first mounting plate 71 and a second mounting plate 72 are mounted parallel to each other on the fixing base 42. A plurality of guide shafts 73 are installed between the first mounting plate 71 and the second mounting plate 72. A guide sleeve 74 is fitted onto each guide shaft 73. The guide sleeve 74 moves laterally along the guide shaft 73. A rotating shaft 43 is mounted on the guide sleeve 74. The handrail turntable 41 is manually driven, causing the guide sleeve 74 to move laterally along the guide shaft 73, thus pulling the latch 44 laterally out from inside the limiting plate 45. Figure 9 and Figure 10 As shown.

[0053] To facilitate insertion into the limiting plate 45 after rotation, the guide sleeve 74 is provided with return springs 75 on both sides. The return springs 75 drive the bayonet 44 to be inserted into the limiting plate 45. When manually driving the bayonet 44 to be pulled out laterally from the limiting plate 45, the spring force of the return spring 75 needs to be overcome.

[0054] Specifically, the reset spring 75 is installed as follows: Figure 11 and Figure 12 As shown; the fixed base 42 is provided with a first barb 76, the guide sleeve 74 is provided with a second barb 77 on both sides, the two ends of the reset spring 75 are respectively connected to the first barb 76 and the second barb 77, and the first barb 76 and the limiting plate 45 are located on the same side.

[0055] The operation of the armrest rotation mechanism 4 is as follows: First, manually drive the first sofa armrest 31 and armrest turntable 41 to move laterally. The guide sleeve 74 moves laterally along the guide shaft 73. At this time, the latch 44 is pulled laterally out from inside the limiting plate 45. During this process, the spring force of the return spring 75 needs to be overcome. Second, manually drive the first sofa armrest 31 and armrest turntable 41 to rotate around the rotating shaft 43. After rotating 180°, one end of the latch 44 contacts the limiting plate 45, and the limiting plate 45 limits the latch 44. Finally, the return spring 75 resets, driving the guide sleeve 74 to move laterally along the guide shaft 73. At this time, the latch 44 is inserted into the limiting plate 45 to achieve fixation.

[0056] The process of using the T-shaped tabletop 8 is as follows: the insert is inserted into the first receiving groove 51, and the tabletop 82 is used to place beverages and portable electronic devices, so that customers can relax and work briefly on the sofa; furthermore, the insert slides laterally along the inside of the first receiving groove 51, thereby adjusting the lateral position of the tabletop 82 on the sofa armrest 3.

[0057] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
