Description

Technical Field

[0001] The present invention relates to the technical field of rail vehicle interior decoration, and in particular to an automatically flippable electric conference table. Background Art

[0002] With the rapid development of rail vehicles such as high-speed trains and people's pursuit of riding comfort and convenience, the technological level of high-speed train interior components has been further improved, and has become more and more humanized. The interior of a high-speed train needs to complete basic functions and maximize the advantages of space within the limited space of the high-speed train. When riding a high-speed train, people often need to work or even conduct video conferences. Therefore, now on a high-speed train, they can only work by placing computers or documents on the table of their seats. The office space is small and office operations are inconvenient. If multiple people are riding the high-speed train at the same time, it is inconvenient to communicate. Therefore, it is necessary to develop a table for use in high-speed train carriages that is convenient for office work and can maximize the use of space. Summary of the Invention

[0007] A rotating motor, a motor gear, a synchronous shaft and a synchronous shaft gear are arranged inside the middle crossbeam. The rotating motor is fixed on the middle crossbeam. The output end of the rotating motor and the motor gear are connected by a key. The synchronous shaft gear is installed at the end of the synchronous shaft. The synchronous shaft gear and the motor gear are engaged. The synchronous shaft is connected to the motor output shaft.

[0008] Furthermore, the panel composition includes a glass panel, a panel end fixing plate, an upper panel fixing plate, an upper panel decorative plate, a lower panel fixing plate and a lower panel decorative plate; the panel end fixing plate is installed on the left and right sides of the glass panel, and the panel end fixing plate is fixedly connected to the connecting shaft; the upper panel fixing plate and the lower panel fixing plate are respectively installed on the upper and lower sides of the glass panel and the panel end fixing plate, the upper panel decorative plate is installed on the upper side of the upper panel fixing plate, and the lower panel decorative plate is installed on the lower side of the lower panel fixing plate.

[0009] Furthermore, a rotating shaft is installed on the upper part of the middle beam rotating member, and a mounting hole is set on the glass panel. After the middle beam rotating member passes through the lower decorative panel and the lower fixed plate of the panel in sequence, the rotating shaft is inserted into the mounting hole and extends to the outside of the mounting hole in the left and right directions; there are 2 middle beam rotating members in total, which are evenly arranged in the left and right directions.

[0013] Furthermore, shaft sleeves are installed on the motor output shaft, motor output transition shaft, driving wheel shaft and connecting shaft to prevent axial movement of the motor output shaft gear, motor output transition shaft gear, driving wheel, ratchet wheel and driven wheel.

[0014] Furthermore, the driven wheel is provided with three protrusions along the circumferential direction, and an arc-shaped groove is provided between the middle protrusion and the protrusions on both sides; a sliding groove is provided on the middle protrusion, and the rotating screw slides in the sliding groove.

When the glass panel is adjusted from a vertical position to a horizontal position, the driving wheel, the ratchet wheel and the driven wheel rotate in opposite directions.

[0019] By adopting the above technical solution, the present invention achieves the following beneficial effects:

[0020] (1) The present invention provides power through a rotating motor, and transmits power to the left column assembly and the right column assembly through the motor gear, the synchronous shaft gear and the synchronous shaft, and drives the driving wheel and the ratchet to rotate synchronously in the same direction through the motor output shaft gear, the motor output transition shaft gear, the driving wheel and the driving wheel shaft, and drives the driven wheel and the driving wheel to rotate in opposite directions through the rotating screw, thereby driving the panel assembly to rotate and realize the adjustment of the horizontal position and the vertical position; when the glass panel is in the horizontal position and the vertical position, the ratchet and the driven wheel form a dead point, thereby locking the rotating screw, and finally locking the position of the glass panel to prevent the glass panel from flipping over, so that when the conference table is not in use, the glass panel can be vertically folded up, and when the conference table is needed, the glass panel can be horizontally opened, thereby maximizing the use of the space in the car, and being safe and stable.

[0021] (2) The power of the rotating motor is transmitted to the left column component and the right column component at the same time through the synchronous shaft, and finally the panel component is driven to rotate at the same time through the connecting shaft. The structure is simple and stable, the power transmission efficiency is high, and the space occupied is small.

[0022] (3) The horizontal and vertical positions of the glass panel can be automatically adjusted by rotating the motor, saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

The automatically flippable electric conference table according to claim 1, characterized in that: The method of use is as follows: when the glass panel (31) is adjusted from a horizontal position to a vertical device, the rotating motor (41) works to drive the motor gear (42) to rotate, the motor gear (42) drives the synchronous shaft gear (44) to rotate, thereby driving the synchronous shaft (43) to rotate; the synchronous shaft (43) drives the motor output shaft (14) of the left column component (1) and the right column component (2) to rotate through the hexagonal transmission rod (46), the motor output shaft (14) drives the motor output shaft gear (16) to rotate, the motor output shaft gear (16) drives the motor output transition shaft gear (17) to rotate, the motor output transition shaft gear (17) drives the driving wheel (18) to rotate, and the driving wheel (18) rotates with The driving wheel shaft (21) rotates, thereby driving the ratchet (20) and the driving wheel (18) to rotate synchronously, and the driving wheel (18) slides in the slide groove (223) through the rotating screw (19), driving the driven wheel (22) to rotate; when the glass panel (31) is in a horizontal position, the rotating screw (19) is located at the outermost end of the slide groove (223), the driving wheel (18) and the ratchet (20) rotate clockwise synchronously, and the rotating screw (19) moves inward along the slide groove (223), thereby driving the driven wheel (22) to rotate counterclockwise; when the rotating screw (19) moves to the innermost end of the slide groove (223), the middle protrusion (221) of the driven wheel (22) rotates to the ratchet (20) The center of the crescent-shaped groove (201); the driving wheel (18) and the ratchet (20) continue to rotate clockwise, and the rotating screw (19) moves outward along the slide groove (223), thereby continuing to drive the driven wheel (22) to rotate counterclockwise, and the ratchet (20) rotates into the arc groove (222) of the driven wheel (22). When the rotating screw (19) moves to the outermost end of the slide groove (223), the driving wheel (18), the ratchet (20) and the driven wheel (22) all rotate 90 degrees, and the outer edge of the ratchet (20) and the arc groove (222) of the driven wheel (22) contact to form a dead point. When the rotating screw (19) continues to move outward, the ratchet (20) continues to rotate clockwise, and the driven wheel The wheel (22) continues to rotate counterclockwise, and the arc-shaped grooves (222) of the ratchet (20) and the driven wheel (22) block each other and cannot continue to rotate relative to each other, thereby locking the rotating screw (19) and preventing it from moving outward; the driven wheel (22) rotates counterclockwise to drive the connecting shaft (23) to rotate counterclockwise, thereby driving the panel end fixing plate (32) to rotate counterclockwise, and finally driving the panel component (3) to rotate from the horizontal position to the vertical position, that is, the glass panel (31) is adjusted from the horizontal position to the vertical position; when the glass panel (31) is adjusted from the vertical position to the horizontal position, the driving wheel (18) and the ratchet (20) rotate counterclockwise, and the driven wheel (22) rotates clockwise.
