Description

Display device

The present invention relates to a display device; and more particularly to a thin display device.

The display is one of the most commonly used information products. In addition to being a must-have device for personal computers, including television program reception and home entertainment and information reception such as video games, the display is also required as a medium for visual image output.

The display usually stands on the table, cabinet, table, etc. by the support arm connecting the foot, and is conveniently viewed by the user. As shown in the conventional display structure 80 of FIG. 1, one end of the support arm 30 is coupled to the base 50, and the other end is coupled to the display 10 in a manner extending from the display 10. Therefore, when the display 10 is transported, in addition to the display 10, additional space is required for accommodating the support arm 30 and the base 50, which will increase the size and weight of the overall package, thereby resulting in an increase in transportation cost. Therefore, there has been developed a display structure in which the support arm is detachable. However, the conventional support arm detachable display structure uses a locking method to fix the display to the support arm to prevent the display from being separated from the support arm when the user adjusts the pitch angle. This method causes inconvenience to the user when the user wants to separate the two, and thus there is room for improvement.

The main object of the present invention is to provide a display device which can save transportation space and cost.

Another object of the present invention is to provide a display device having a small storage volume.

The display device of the present invention includes a display device body, a support arm, and a connection end housing. The display device body includes a housing, a card slot, and a spring piece. The housing has a housing surface. The card slot is formed in the housing. The elastic piece is disposed on the housing and is selectively movable back and forth. The support arm is selectively detachably coupled to the housing, including a support portion and a connection end. The connecting end is disposed at one end of the support portion, and includes a connecting sheet and a hook. A through hole is formed in the connecting sheet. The hook protrudes outward from one of the connecting sheets. The connecting end housing has an elastic portion, and the elastic portion has a pillar extending forward, which is aligned with the elastic piece. Wherein, when the hook protrudes into the card slot to the first position, the connecting sheet presses the elastic piece to move forward, and when the hook slides along the card slot to the second position, the hook is engaged with the card slot, and the elastic piece is ejected backward and At least partially extending into the through hole to limit the displacement of the connecting end relative to the housing along the slot; when the user presses the elastic portion, the column presses the elastic piece forwardly away from the through hole to release the limiting connecting end from the housing along the slot The displacement is such that the user can apply force to move the hook in the slot, thereby separating the support arm from the housing.

The connecting end housing has a U-shaped housing in which a receiving space and an opening are formed, and a connecting end of the receiving space receiving portion is formed. The elastic portion is located at an apex of the U-shaped housing, and the pillar extends from the apex of the U-shaped housing toward the opening direction. The housing is recessed into the interior of the display device body to form an inner concave portion, and the card slot and the elastic piece are respectively formed and disposed in the inner concave portion. The hook is a ladder structure, and the inclined surface of the ladder structure faces the direction in which the hook and the card slot are engaged, so that the deeper the hook enters the card slot, the narrower the hook spacing is. The shrapnel is riveted to the surface of the housing and has a higher elasticity than the housing, so that the housing remains substantially stationary as the shrapnel selectively moves back and forth.

The opposite side edges of the connecting sheet respectively have lugs, and the two lugs are respectively connected to the supporting portion. The hook is disposed between the two lugs of the connecting sheet, so that the external force received by the connecting sheet is more uniformly transmitted to the supporting portion. The through hole is formed between the two lugs of the connecting sheet, and the column extends from the elastic portion to the through hole and is located between the two lugs, so that the external force of the elastic portion that is pressed by the user to press the elastic portion can be more uniformly transmitted to Support section.

The two lugs are respectively connected to the support portion, so that the display device body can be rotated around the horizontal axis to adjust the pitch angle, and the card slot extends parallel to the horizontal axis, so that the vertical adjustment of the tilt angle of the display device body is applied by the user. The external force does not affect the combination of the hook and the horizontal direction of the card slot. The connecting end casing can be coupled to the display device body such that the elastic portion is adjusted in accordance with the display device body for pitch angle adjustment so that the forwardly extending column continues to be aligned with the elastic piece. The connecting end casing may also be coupled to the connecting sheet such that the elastic portion is adjusted in accordance with the tilting angle of the display device body so that the forwardly extending pillar continues to be aligned with the elastic piece.

The display device body further includes a fixing piece fixed to the housing and forming a sandwich space together with the surface of the housing. The card slot is formed on the fixing piece and communicates with the interlayer space. The elastic piece is disposed on the fixed piece and is selectively movable back and forth. Wherein, when the hook protrudes into the card slot to the first position, the connecting sheet presses the elastic piece to move forward, and when the hook slides along the card slot to the second position, the hook is engaged with the card slot, and the elastic piece is ejected backward and At least partially extending into the through hole to limit the displacement of the connecting end relative to the fixing piece along the slot; when the user presses the elastic portion, the column presses the elastic piece forwardly away from the through hole to release the limiting connecting end from the fixing piece along the slot The displacement is such that the user can apply force to move the hook in the slot, thereby separating the support arm from the fixed piece.

The housing is recessed toward the inside of the display device body to form an inner recess, and the fixing piece is fixed to the inner recess. The elastic piece is riveted to the surface of the fixing piece, and has higher elasticity than the fixed piece, so that the fixing piece remains substantially stationary when the elastic piece is selectively moved back and forth.
