detailed description

The liftable device of the present utility model is shown in the figure, wherein Fig. 1 is a three-dimensional schematic diagram of the liftable device 1000 of the present utility model, and Fig. 2 is an exploded schematic diagram of the liftable support device 1000 of the present utility model, the liftable support device 1000 includes a bracket 1 , two slide rail modules 2 , a sliding part 3 , two air rods 4 and a connecting part 5 .

First, the structure of the bracket 1 is described. The bracket 1 has a front cover 11 , two fixing plates 12 , a rear cover 13 , an accommodating space 14 and three buffer pads 15 . The front cover 11 is generally a flat rectangular parallelepiped hollowed out in the center. The front cover 11 and the rear cover 13 jointly define an accommodating space 14. The accommodating space 14 generally extends along a first direction S, and the fixing plate 12 extends along the first direction S. The direction S is arranged at intervals on the front cover body 11; the front cover body 11 has a first platform 112 adjacent to the accommodation space 14, two second platforms 113 and two linear through grooves 115 communicating with the accommodation space 14, the The second platforms 113 are arranged at intervals and protrude into the center of the accommodating space 14 ; in addition, the buffer pads 16 are respectively arranged on the second platform 113 and a side away from the first platform 112 . It should be added that in this embodiment, the front cover 11 is a die-casting part, and the rear cover 13 is a plastic plate or an aluminum plate, but it is not limited thereto.

Each slide rail module 2 has an outer rail 21 and an inner rail 22 extending along the first direction S respectively, and each inner rail 22 is slidably arranged in an opening of each outer rail 21 along the first direction S, and each outer The rails 21 are fixedly connected to a fixed plate 12 respectively.

The slider 3 has a top plate 31, two opposite side wings 32, a front convex plate 33 and two friction blocks 34. The side wings 32 extend from the two side edges of the top plate 31 along the first direction S and are parallel to the fixed plate 12. , so that the sliding member 3 is an inverted U shape. The side wings 32 are respectively connected to the inner rails 22, and each friction block 34 is connected to each side wing 32 and is located below each inner rail 22. The outer rail 21 rubs to generate frictional force. In addition, the front convex plate 33 is exposed outside the front cover body 11 , has a U-shaped cross section, and passes through the linear slot 115 of the front cover body 11 to connect with the opposite side wings 32 .

Each of the air pressure rods 4 has a pressure tube 41 and a piston rod 42. One end of the piston rod 42 is inserted into the pressure tube 41 to slidably connect with the pressure tube 41. The other end of the piston rod 42 is fixedly connected to the first on the plurality of second clamping holes 112 a of the platform 112 . A closed space is formed inside the pressure tube 41 , and the other end of the pressure tube 41 has a plurality of clamping blocks 411 fixed in a plurality of first clamping holes 311 of the top plate 31 so that the pressure tube 41 is fixedly connected to the slider 3 .

It should be noted that, in other embodiments of the present utility model, the pressure tube 41 can also be turned upside down, so that the block 411 of the pressure tube 41 is locked with the second hole 112a, and the end of the piston rod 42 is locked with the second hole 112a. A locking hole 311 is locked. Or, in other embodiments of the present invention, the top plate 31 and the pressure pipe 41 or the first platform 112 and the piston rod 42 can be combined by screwing, which will not be repeated here.

The connecting piece 5 is connected to the front convex plate 33 , and the connecting piece 5 can be connected to a display module (not shown in the figure), so the display module can slide on the bracket 1 through the sliding piece 3 . In addition, the connecting member 5 itself may further include a hinge, so that the display module can adjust the tilted viewing angle, or rotate between landscape and portrait positions.

When the slider 3 slides toward a lowest position along the first direction S (that is, the slider 3 slides downward), it can compress the air pressure rod 4, that is, the slider 3 drives the pressure tube 41 downward Move, so that the piston rod 42 compresses the closed space in the pressure tube 41 to generate a reverse elastic force, and the reverse elastic force matches the friction force between the components (including the friction force generated by friction between the friction block 34 and the outer rail 21) It can just compete with the gravity of the display module to achieve a stop effect.

Please refer to FIG. 3 and FIG. 4 , which are schematic diagrams of the slider 3 at a lowest position and a highest position, respectively. When the slider 3 continues to slide downwards, eventually one end of each side wing 32 will be in contact with the buffer pad 15 located on the second platform 113, which is the lowest position set by the pressure tube 41, which will allow the pressure tube 41 to be in contact with the pressure tube 41. The first platform 112 maintains a distance D, so as to avoid excessive compression of the air rod 4 or damage of the pressure tube 41 hitting the first platform 112 . Furthermore, by adjusting the setting position of the second platform 113, the stroke length of the slider 3 can be adjusted correspondingly, that is, the distance from the highest position to the lowest position of the slider 3 can be adjusted according to the position of the second platform 113, Similarly, the maximum sliding distance of the pressure tube 41 can be controlled, so that the elastic force of the air pressure rod 4 can be adjusted. In addition, the top plate 31 of the slider 3 is also provided with a protrusion 312. When the slider 3 slides from the lowest position to the highest position again, the protrusion 312 contacts the buffer pad 15 on the side away from the first platform 112, so that Prevent the top plate 31 of the slider 3 from colliding with the top of the front cover 11 to cause abnormal noise.

For example, if the weight of the display module is 5 kg, two air rods 4 with a load capacity of 2.5 kg can be selected, and the diameter of the air rod 4 with a load capacity of 2.5 kg must be smaller than that of a support with a load capacity of 5 kg. Therefore, when two pneumatic rods 4 with a load capacity of 2.5 kg are arranged side by side on the slider 3, the utility model support device 1000 can maintain the lightness and thinness viewed from the side. Furthermore, the arrangement of the plurality of air pressure rods 4 also helps to increase the stability of the sliding part 3 during the sliding process, and avoids the sliding part 3 from shaking from side to side during the sliding process. In addition, the utility model can also adjust the number of air rods 4 according to the demand. For example, if it is adjusted to four air rods with a load capacity of 1.25 kg, the support frame can be thinner and lighter when viewed from the side.

To sum up, the arrangement of a plurality of air pressure rods in the present invention can effectively improve the sliding stability of the slider, and the shape of the slider should match the shape of the top of the front cover, while maintaining the lightness and thinness of the supporting device.

The above-mentioned embodiments are only used to illustrate the utility model and explain the technical features of the utility model, and are not used to limit the scope of protection of the utility model. Any changes or equivalence arrangements that can be easily accomplished by those skilled in the art belong to the scope of the utility model, and the scope of protection of the utility model shall be based on the scope of the patent application.
