[Prior Art] In modern information equipment, display devices are widely used in various fields. When the display panel of the display device is kept at an appropriate angle with the observer, the best display effect is observed, so different users need to adjust different angles to observe the display screen. In order for the user to see the best visual picture, a height-adjustable display device is required. 1 and FIG. 2, FIG. 1 is a schematic exploded view of a prior art display device, and FIG. 2 is a side view of the display device shown in FIG. The display device 1 includes a base 11, a docking device 12, and a display panel 13. The pivoting device 12 is fixed to the base u and supports the display panel 13, and the splicing device 12 can adjust the height of the display panel 13 relative to the base 11. The base 11 is a disk that is placed on the surface of the water platform to maintain the center of gravity of the display device 1 stable. The pivoting device 12 includes a tubular cylinder 121, a compression spring 123, a sliding body 125, a magnet group 127 that attracts each other, a set of rings 129, and a nut 130. The tubular cylinder 121 has a hollow cylindrical structure, and the hollow portion forms a receiving space, and the tubular cylindrical member 21 is vertically fixed at a center position of the base 11. The compression spring 丨 23 is received in the accommodating space of the tubular cylinder 121. The sliding body 125 is sleeved on the end portion of the compression spring 123 and is received in the receiving space of the tubular cylinder 1 21. Form No. A0101 Page 4 / Total 24 pages The ring 129 0993310918-0 1335760 099 Aug 30 It is sleeved on the outer side of the tubular cylinder 121 and can rise or fall freely along the tubular cylinder 121. The two portions of the mutually attracting magnet group 127 are respectively disposed on the outer periphery of the sliding body 125 and the inner side of the collar 129, and the two portions of the mutually attracting magnet group 127 are separated by the side wall of the tubular cylinder 121. . The nut 130 covers the tubular cylinder 121 away from the base u end to block the compression spring 123 and the sliding body 125 from being disengaged from the tubular cylinder 121. The display panel 13 is a display terminal for displaying a kneading surface, which is fixed to the collar 129 by a screw bolt, and can freely ascend or descend along the tubular cylinder 121 along the collar 129. [〇〇〇7] The working principle of the display device 1 is as follows: since the two portions of the magnet group 127 that are attracted to each other are respectively disposed on the collar 129 and the sliding body 125, two of the magnet groups 127 are provided. The gravitational force between the portions, clamping the side wall of the tubular cylinder 121, generates friction between the sliding body 125 and the collar 129 and the side wall of the tubular cylinder 121; and the compression spring 123 applies an elastic force to support the sliding body. 125, the sliding body 125 is caused to generate an upward sliding, and the elastic force of the compression spring 123 is appropriately adjusted, and the friction between the sliding body 125 and the collar 129 and the side wall of the tubular cylinder 21 is generated. The elastic force of the compression spring 123 and the gravity of the display panel 13 act together on the collar 129 to ensure that the balance is at a suitable height. 096123677 δ is an upper external force applied to the display panel 13 when the display panel 13 is to be raised, and if the sum of the external force and the compression spring i23 is greater than the sum of the gravity of the display panel 13 and the friction force, The display panel 13 rises to the set height along with the collar 129; otherwise, the display panel 13 is under 0993310918-0 Form No. A0101 Page 5 / Total 24 Page 1335760 __ August 30, 30, the replacement page is reduced to the set height When the external force is removed, the frictional force cooperates with the elastic force of the compression spring 123 and the gravity of the display panel 13 to ensure that the display panel 13 is stationary at the set height. According to the above principle, the rise and fall adjustment of the display panel 13 of the display device 1 is achieved.

The plurality of second fixing holes 730 and the plurality of fourth fixing holes 230 respectively 096123677 Form No. A0101 Page 9 / Total 24 pages 0993310918-0 1335760 On August 30, 2008, the shuttle is replacing the page, and by the nut (not shown) The supporting plate 232 is fixed to the second body 700 of the sliding unit 207 , and the pressing rod 356 of the first fixing portion passes through the hole 236 of the supporting plate 232 . The second connecting member of the display panel 26 cooperates with the first connecting member 234 of the locking device 23 to fix the display panel 26 to the supporting plate 232, so that the display panel 26 is fixed to the sliding unit 207 of the height adjusting device 20. . The display device 2 can adjust the relative height of the display panel 26 by adjusting the height of the sliding unit 207 relative to the base 209. [0023] When the display panel 26 is at the maximum relative height, the distance between the contact points of the elastic member 205 and the second sliding arm 711 is the largest, and the deformation caused by the clamping of the sliding unit 207 is minimized, and the generated elastic force is also minimized. . The spring force acts obliquely upward on the sliding unit 207, which can be decomposed into a first component in the vertical direction and a second component in the horizontal direction. The first component is smaller than the gravity of the display panel 26, that is, the force of the display panel 26 and the first component force are vertically downward, and the display panel 26 has a downward motion. However, due to the pressure of the second component force on the sliding unit 207, the sliding unit 207 has a forward pressure relative to the chute unit 304, and the forward pressure causes the sliding unit 207 and the chute unit 304 to have a a maximum static friction force, and the resultant force of the first component force and the gravity is less than or equal to the maximum static friction force, so that the resultant force cannot overcome the maximum static friction force, and thus the display panel 26 cannot move downward. At this time, the sliding unit 207 is subjected to a vertical upward static friction force which balances the resultant force of the first component force with the gravity of the display panel 26, so that the display panel 26 is at a maximum relative height. [0024] If the relative height of the display panel 26 is to be lowered, an external force is applied to press the display. 096123677 Form No. A0101 Page 10 of 24 0993310918-0 1335760 - On August 30, 099, the shuttle is replacing the display panel 26. The sliding unit 207 is lowered along the chute 340. The distance between the second sidewall 712 of the sliding arm 711 of the sliding unit 207 and the two rolling columns 520 of the elastic member 205 is gradually reduced, and the elastic deformation of the elastic piece 50 is gradually increased, and the elastic force is gradually increased. Thereby, the first component force and the second component force also gradually increase. [0025] When the display panel 26 is moved to a desired relative height, the external force is cancelled. The increase in the first component force causes the resultant force of the display panel 26 to change. The increase of the second component force increases the horizontal positive pressure of the sliding unit 207 relative to the chute unit 203, and the maximum static friction between the sliding unit 207 and the chute unit 203 increases. [0026] If the first component force is still less than the gravity of the display panel 26, the resultant force of the first component force and the gravity of the display panel 26 is still vertically downward, because the first component force increases, The resultant force is reduced so that it is still less than the maximum static friction so that the display panel 26 is relatively stationary at a desired height. At this time, the static friction force of the sliding unit 207 is still balanced with the combined force of the first component force and the gravity of the display panel 26, and the direction is still vertically upward, and the magnitude is equal to the combined force. [0027] If the first component is equal to the gravity of the display panel 26, the display panel 26 has no movement tendency, and the static friction between the sliding unit 207 and the chute unit 203 is zero, and the display panel 26 is opposite. Still at a desired height 〇 [0028] If the first component force is greater than the gravity of the display panel 26 at this time, the combined force of the first component force and the gravity of the display panel 26 is vertically upward. The resultant force causes the display panel 26 to have a vertical upward movement tendency, and the second component force is increased by 096123677. Form number A0101 page 11/24 pages 0993310918-0 1335760 __ August 30, 30, the correction replacement page is still large The maximum static friction between the sliding unit 207 and the chute unit 304 is increased. Therefore, the resultant force of the first component and the display panel 26 cannot overcome the maximum static friction force, so that the display panel 26 cannot move upward. The sliding unit 207 is subjected to a vertical downward static friction force which balances the first component and the resultant force of the display panel 26 to cause the display panel 26 to rest at a desired height. [0029] When the display panel 26 is at the minimum relative height, the resultant force of the first component force and the gravity of the display panel 26 is still vertically upward, and is less than or equal to the maximum static friction between the sliding unit 207 and the chute unit 203. The force, such that the display panel 26 is stationary at the minimum relative height. When the display panel 26 is pressed down to the minimum relative height, the second end (not labeled) of the hole 236 of the support plate 232 abuts against the pressing rod 356, and then continues to apply an external force to press the display panel 26, the display panel 26 It is not possible to continue moving toward the base 209, thereby indicating that the display panel 26 is already at the minimum relative height. [0030] When it is required to raise the relative height of the display panel 26, an external force is applied to pull the display panel 26, and when the display panel 26 is moved to a desired relative height, the external force is cancelled, so that the display panel 26 is relatively stationary. Expect a high degree. [0031] When the display panel 26 is raised to the maximum relative height, the first end (not labeled) of the hole 236 of the support plate 232 opposes the abutment bar 356. If the external display of the display panel 26 is continued, the display panel 26 cannot continue to move away from the base 209 because the pressing lever 356 blocks the support plate 232 to indicate that the display panel 26 is located at the maximum relative position. Height, and can avoid the improper display of the display panel 26 from the height adjustment device 20 096123677 Form No. Α0101 Page 12 / Total 24 Page 0993310918-0 Correction Replacement Page 1335760 of 099 [0032] Compared to the previous The display device 2 uses an elastic member 205 to cooperate with the sliding unit 207 and the chute unit 203 to realize the lifting and lowering of the display panel 26 relative to the base 209, thereby avoiding the use of magnetic components such as magnets, and reducing magnetic interference due to magnetic interference of the magnet. The effect of the display device 2 is improved by reducing the influence. The present invention is not limited to the above embodiments.
