At the same time, the bed assembly 40, the cabinet assembly 50, the articulated arm 60, and the gas spring assembly 70 work together to switch back and forth between complete sleeping needs and office needs, solving the problem of not being able to meet the needs of consumers.

[0049] In the first aspect of the utility model, as a preferred embodiment, specifically: the lower part of the desk body 10 is protrudingly provided with an end hinge 11, and the lower end of the end hinge 11 is hinged to the upper part of the swing arm assembly 20. The swing arm assembly 20 is U-shaped, and the upper part of the swing arm assembly 20 is provided with an upper hinge end 22, and the upper hinge end 22 is hinged to the lower end of the end hinge 11. The lower part of the swing arm assembly 20 is provided with a lower hinge end 23, and the lower hinge end 23 is hinged to the base assembly 30. The above-mentioned hinge relationship is hinged in the form of a rotating shaft. Of course, other hinge modes can also be used when specifically applicable.

[0050] Specifically, when the invisible bed is unfolded, the bed body 6 is placed on the desk body 1, and the desk body 10 and the end hinges 11 also function as bed legs, and have good stability.

[0051] In the first aspect of the utility model, as a preferred embodiment, when in office state, the extension direction of the base assembly 30 is parallel to the extension direction of the office desk body 10. Specifically, the base assembly 30 includes two first steel pipes 31 and a second steel pipe 32, and the two first steel pipes 31 are respectively connected to the two ends of the second steel pipe 32 and are distributed in a U shape. The base assembly 30 plays the role of a load-bearing frame, and adopts a steel pipe welded frame structure to ensure the load-bearing capacity of the office desk. Taking the upper hinge of the swing arm assembly 20 as an example, when the office desk weighs 35 kilograms, it needs to withstand a maximum horizontal pulling force of about 70 kilograms. Therefore, the office desk as a whole needs to have strong rigidity to ensure that it does not deform during movement.

[0052] Taking into account the load-bearing capacity and the convenience of transportation, the interior of the desk body 10 is mainly composed of a crossbeam, a front frame, and a rear frame, which are assembled by bolts. There are mounting holes on the front frame and the rear frame for mounting the desktop, partitions, and drawers. Specifically, the desk body 10 is provided with a plurality of drawer assemblies 13. Specifically, the drawer assemblies 13 are equipped with drawer slide rails.

[0053] In the first aspect of the utility model, as a preferred embodiment, the base assembly 30 further includes a reinforcing rib 33, and both ends of the reinforcing rib 33 are respectively welded and fixed to the first steel pipe 31 and the second steel pipe 32 to improve the overall strength.

[0054] In the first aspect of the utility model, as a preferred embodiment, the upper portion of the vertical cabinet assembly 50 is provided with a vertical cabinet fixing member 501 for fixing to a wall, so as to facilitate installation.

[0055] In the first aspect of the utility model, as a preferred embodiment, when in an office state, the extension direction of the desk body 10 is perpendicular to the cabinet assembly 50 , and the swing arm assembly 20 is perpendicular to the desk body 10 .

[0056] In the first aspect of the utility model, as a preferred embodiment, when in a fully expanded state, the extension direction of the office desk main body 10 is perpendicular to the cabinet assembly 50, the swing arm assembly 20 is parallel to the office desk main body 10, the extension direction of the swing arm assembly 20 coincides with the extension direction of the base assembly 30, and the swing arm assembly 20 and the base assembly 30 are both in contact with the ground.

[0057] Please refer to Figure 15-16As a preferred embodiment, the office desk structure that matches the invisible bed also includes a backrest assembly (90), and the backrest assembly (90) includes a movable backrest (91), a hinge (92), and a frame (93). The hinge (92) is installed inside the frame (93), and the movable backrest (91) is arranged at the end of the frame (93). In the prior art, similar structures generally require pillows and bedding to be re-laid each time they are used. When they are put away after use, the pillows and bedding need to be put away first, which is inconvenient to use. The present application can solve the above problem. Its goal is to be stationed in a formal small room and to facilitate consumers' daily use. The purpose of adding the "movable backrest (91)" is that when the bed is unfolded, the movable backrest (91) is in the position as follows: Fig.16 As shown, it can be used as a backrest. When the bed is folded, the movable backrest (91) leans against the bed box backboard (such as Fig.15 As shown), the pillows and bedding can be held in place, thus avoiding the trouble of consumers having to make the bed again every time.

[0058] In summary, this application also has the following advantages:

[0059] (1) The steel pipe welded structure is used as the load-bearing frame, and the parts made of wooden boards are used as functional parts, taking into account both structural strength and office comfort requirements.

[0060] (2) The main body of the desk is assembled by a crossbeam, a front frame, and a rear frame by screws. The front frame and the rear frame are welded together by steel pipes and have a good load-bearing capacity. The main body of the desk is decomposed into three parts, which is convenient for transportation.

[0061] Regarding the selection of gas spring assembly 70: Due to the heavy weight of the desk and the weight of the items in the drawer, a gas spring with a larger thrust is required; however, if the thrust of the gas spring is always large, it will be very difficult to pull the invisible bed out of the bed box. Therefore, after calculation and analysis, it is appropriate to choose a two-stage gas spring.
