[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0029] The present embodiment provides an electrically retractable pitch arm. Aiming at a work environment that takes into account both office and meeting modes, the arm supports a monitor so that the monitor can be raised and lowered. In the unfolded state, the viewing angle required for office use is met, and the support angle of the monitor is fixed; in the folded state, the monitor is folded to meet the requirements of meeting mode use (without blocking the faces of meeting participants).
[0030] like Figure 1-Figure 5 As shown, the electric telescopic pitch arm comprises: a fixed base 1, a support block 2, a telescopic arm body, a pitch mechanism 6 and a display fixing seat 7; wherein the telescopic arm body comprises: an electric telescopic mechanism, an arm body A section 3 and an arm body B section 4; the arm body A section 3 and the arm body B section 4 are both hollow structures, serving as the outer shell of the electric telescopic mechanism, and at the same time serving as a limit and guide for the telescopic movement of the electric telescopic mechanism.
[0031] The fixed base 1 is fixed on a load-bearing beam or column below the workbench surface 8 to provide a mounting surface for the telescopic arm body; the fixed base 1 serves as the basic positioning and load-bearing function for the telescopic arm body.
[0032] One end of the arm body section A 3 in the retractable arm body passes through the workbench surface 8 and is connected to the fixed base 1 (such as by screws); the arm body section A 3 is installed on the fixed base 1 at a set inclination angle (such as 30°) to the horizontal plane, thereby ensuring that the support angle of the display is fixed during extension and retraction; as an example, the mounting surface provided by the fixed base 1 is an inclined plane with a set inclination angle, and the arm body section A 3 is supported on the inclined plane.
[0033] One end of the arm body section B 4 is sleeved inside the arm body section A 3 and slidingly cooperates with the arm body section A 3; to prevent the arm body section B 4 from rotating around the axis relative to the arm body section A 3, in this example, the cross-sections of the arm body section A 3 and the arm body section B 4 are both rectangular; and strip protrusions are provided on the four outer sides of the arm body section B 4 along its extension direction as limiting slide rails 5, and correspondingly, slide grooves cooperating with the limiting slide rails 5 are provided on the four inner sides of the arm body section A 3, thereby ensuring that the arm body section B 4 can only be extended and retracted relative to the arm body section A 3.
[0034] An electric telescopic mechanism such as an electric push rod is arranged inside the arm body section A 3 and the arm body section B 4, wherein the fixed end of the electric telescopic mechanism is connected to the arm body section A 3 or the fixed base 1, and the telescopic end is connected to the arm body section B 4, for pushing the arm body section B 4 to telescope relative to the arm body section B 4.
[0035] In addition, a support block 2 is provided on the side of the arm body A section 3 (i.e., the side facing the workbench surface 8), and the support block 2 is supported on the workbench surface 8. To ensure reliable support, an anti-slip pad can be provided on the support surface of the support block 2. The support block 2 supports the body A section 3 and limits the position, thereby preventing the telescopic arm body from displacement and shaking.
[0036] The other end of the arm body B section 4 is connected to a display fixing seat 7 through a pitch mechanism 6. The display fixing seat 7 is used to fix and install the display. For example, the display fixing seat 7 is connected to the mounting hole on the back of the display with screws. The display is adjusted in pitch angle by the pitch mechanism 6, and the support angle of the display is fixed during the pitch adjustment. Therefore, when multiple displays are arranged in a large conference room, the support angles of all displays can be uniform, and the adjustment of the display pitch angle is not affected.
[0037] As an example, the display fixing base 7 is rotationally connected to the arm main body section B 4 through the support ear, and the pitch mechanism 6 is used to drive the display fixing base 7 to rotate around the rotation connection portion between it and the arm main body section B 4 to adjust the pitch angle; if the pitch mechanism 6 adopts a motor pitch device, it includes a drive motor and a pitch axis; the drive motor is fixed on the arm main body section B 4, the power output end of the drive motor is connected to the pitch axis, and the display fixing base 7 is rotationally connected to the arm main body section B 4 through the pitch axis.
[0038] Thus, the electrically retractable pitch arm can support the display at a set tilt angle. After being fixed to the workbench body through the fixed base 1 and the support block, the electrically retractable pitch arm is in a tilted state at a set angle (such as 30°); when the display needs to be used, the arm body B section 4, the pitch mechanism 6 and the display fixing seat 7 are pushed out relative to the arm body A section 3 as a whole through the cooperation of the electric telescopic mechanism and the limit guide rail 5; an electric push rod is used as the electric telescopic mechanism, and the stroke can reach 25 cm. During the unfolding process, the pitch mechanism 6 is adjusted synchronously, and the display can be adjusted to a vertical state perpendicular to the staff's line of sight, such as Figure 4 When the display is not needed, the electric telescopic mechanism and the limit rail 5 drive the arm body B section 4, the pitch mechanism 6 and the display fixing seat 7 to be recovered relative to the arm body A section 3 as a whole, and after recovery, the display pitch angle can also be adjusted, such as Figure 5 shown.
[0039] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
