Referring to fig. 1 and 2, the base 1 of the computer case is used to support the suspension arm 3 and the rotating seat 2, and the base 1 may be provided with a wheel assembly to drive the whole computer case to move, or a step may be provided on the base 1 to facilitate a user to get into the seat 21 on the base 1. In the patent, the base 1 is a square frame formed by assembling a plurality of plates and sectional materials, the frame is provided with a plurality of convex edges with certain aesthetic feeling, and a support frame 11 which is raised on the base 1 and is used for connecting the rotating seat 2; in this embodiment, the two support frames 11 are provided and are located at the left and right sides of the base 1 in a protruding manner.
As shown in fig. 2, the shape of the rotating seat 2 is adapted to the shape of the base 1, and is used for mounting and carrying the seat 21, and a driving assembly for driving the seat 21 to move back and forth, or a leg pad 24, a backrest and other components attached to the seat 21, and a driving assembly for driving the leg pad 24 and the backrest to move are further installed on the rotating seat 2. In this example, the rotating seat 2 includes connecting frames 22 disposed at two sides thereof, the connecting frames 22 are specifically vertically disposed profile plates, the outer end surfaces of the connecting frames 22 are vertically intersected with the supporting frame 11, the first arc-shaped sliding rail 41 and the first rolling block 42 are respectively disposed at opposite sides of the connecting frames 22 and the supporting frame 11, and the first rolling block 42 is limited in the first arc-shaped sliding rail 41 by adjusting the distance between the connecting frames 22 and the supporting frame 11, so as to fix the rotating seat 2 at the upper side of the base 1. The arc of the first arcuate rail 41 is related to the distance between the seat 21 and the rotatable seat 2, so that the arc of the first arcuate rail 41 is determined at the time of shipment to make the rotatable seat as centered as possible on the user in the seat. The first telescopic cylinder 43 is mounted on the base 1, and is configured to push the rotating base 2 to move along the arc direction of the first arc-shaped sliding rail 41, as shown in fig. 3, 4, and 6, an installation bin 12 for installing the first telescopic cylinder 43 is centrally disposed in the base 1, the lower end of the rotating base 2 is provided with a connecting arm 23 facing the base 1, the connecting arm 23 is located between the two connecting frames 22, one end of the first telescopic cylinder 43 is hinged in the installation bin 12, and since the position of the first telescopic cylinder 43 changes when the first telescopic cylinder 43 is pushed, the first telescopic cylinder 43 needs to be hinged in the installation bin 12, and the other end of the first telescopic cylinder 43 is hinged to the connecting arm 23; the first telescopic cylinder 43 in the embodiment adopts the motor push rod, and the motor push rod has the advantage that a gas path does not need to be arranged, so that the universality of a computer cabin is improved; when the motor push rod works, the driving end of the motor push rod makes telescopic motion, in the telescopic process, the whole rotating seat 2 is pushed to move along the first arc-shaped slide rail 41, at the moment, the first rolling block 42 rolls in the first arc-shaped slide rail 41, and the first rolling block 42 can be a bearing piece and is used for ensuring smooth movement; the whole seat 21 and the rotating seat 2 are guided to rotate by the connection of the first rolling block 42 and the first arc-shaped sliding rail 41 by taking the gravity center of the user when leaning on as the center of circle, so that when the rotating seat 2 works, the gravity center of the user is basically unchanged, namely zero gravity adjustment is carried out, and the comfort of adjustment is greatly increased. It should be noted that the center of gravity of the user varies from person to person, and therefore, when the computer cabin in this patent is shipped from factory, the different radians of the first arc-shaped slide rail 41 are set to make the center of rotation circle of the rotation seat 2 as close as possible to the center of gravity of the user when the user leans on, or even coincide with the center of gravity, so as to adapt to different users; meanwhile, when a user leans on the seat 21, most of the gravity of the human body is transmitted to the base 1 through the transmission structures on the support frame 11 and the connecting frame 22, and the gravity of the human body is supported through the base 1, and for the first telescopic cylinder 43, only part of the gravity of the rotating base 2 and part of the gravity of the human body need to be supported, so that the first driving assembly in the patent prevents the first telescopic cylinder 43 from being damaged under the long-term action of the gravity of the user by adjusting the stress condition of the first telescopic cylinder 43, and the service life of the first telescopic cylinder 43 is prolonged; because the load of the first telescopic cylinder 43 is reduced, the specification of the first telescopic cylinder 43 can be correspondingly reduced when the first telescopic cylinder 43 is selected and assembled, so that the cost is saved.
