Detailed Description

Fig. 2 is a schematic view of the lifting assembly carrying the electronic device, and fig. 3 is a schematic cross-sectional view of fig. 2. Referring to fig. 2 and fig. 3, the lifting assembly 300 of the present embodiment is, for example, a sleeve type, and is suitable for carrying the electronic device 400 and adjusting the height of the electronic device 400. The electronic device 400 may be a display screen, a lamp, a tablet, a smart phone, or other devices that may need to be used in the lifting assembly 300, and is not limited to the display screen illustrated in the embodiment.

In view of the above, the lifting assembly 300 includes the sleeve holder 310, the sleeve holder 310 includes a base 312, a supporting shaft 314 and a first sleeve 316, wherein the supporting shaft 314 and the first sleeve 316 are disposed perpendicular to the base 312, and the first sleeve 316 is sleeved outside the supporting shaft 314. The lifting assembly 300 further includes a second sleeve 320 sleeved outside the sleeve base 310, wherein a spiral sliding groove 322 is defined on a wall of the second sleeve 320. The lifting assembly 300 further includes a sliding member 330, the sliding member 330 has a third sleeve 332 and a sliding block 334 extending from the wall of the third sleeve 332 in the radial direction of the third sleeve 332, the third sleeve 332 is located inside the first sleeve 316 and the second sleeve 320, the sliding block 334 is correspondingly embedded in the spiral chute 322, and the electronic device 400 is suitable for being assembled to the sliding block 334, so that the electronic device 400 can determine the height according to the position of the sliding block 334 on the spiral chute 322. The lifting assembly 300 further includes an elastic element 350 sleeved on the supporting shaft 314, and the elastic element 350 is located in the first sleeve 316 and extends into the third sleeve 332, wherein two ends of the elastic element 350 are abutted against between the third sleeve 332 and the base 312. The elastic element 350 may be a spring.

In detail, the slider 334 is inserted into the spiral chute 322 from opposite sides of the wall of the third sleeve 332 in the radial direction of the third sleeve 332, extending back and forth. The symmetrical arrangement of the slider 334 facilitates a balanced and smooth movement of the slider 334 along the spiral runner 322.

In view of the above, the base 312 may further include a weight block (not shown), wherein the weight block may provide enough weight to the base 312 to prevent the lifting assembly 300 from toppling over due to the over-weight of the electronic device 400 after the electronic device 400 is mounted on the slider 334.

In addition, the second sleeve 320 further has a sleeve portion 324 and a turntable portion 326, the sleeve portion 324 is sleeved outside the first sleeve 316, and the turntable portion 326 is sleeved on the base 312, wherein the position of the slider 334 in the spiral sliding groove 322 can be adjusted by rotating the turntable portion 326. Further, the slider 334 is designed as a shaft disposed on the outer surface of the third sleeve 332 and extending in the radial direction of the third sleeve 332, that is, the slider 334 of the present embodiment does not penetrate the inside of the third sleeve 332.

The elastic element 350 provides an elastic restoring force to push the third sleeve 332, and the sliding block 334 of the third sleeve 332 abuts against the groove wall of the spiral chute 322, and when the elastic restoring force is balanced with the weight of the electronic device 400, the position of the sliding block 334 in the spiral chute 322 is fixed.

Incidentally, the elastic element 350 may be provided in plural, for example, the elastic element 351, the elastic element 352, and the elastic element 353, and an elastic coefficient of at least one of the elastic element 351, the elastic element 352, and the elastic element 353 is different from an elastic coefficient of the remaining elastic element 351, the elastic element 352, and the elastic element 353. By using the elastic elements 351, 352 and 353 with different elastic coefficients, the force variation during the lifting process of the electronic device 400 can be adjusted to improve the smoothness of operation.

The lifting assembly 300 further includes a plurality of sliding elastic pieces 360 sleeved on the supporting rod, and one sliding elastic piece 360 is disposed between any two adjacent elastic elements 351, 352 and 353. The sliding elastic piece 360 is used to separate the adjacent elastic elements 351, 352, 353, and can move in the first sleeve 316 along the axial direction of the first sleeve 316 along with the expansion and contraction of the elastic elements 351, 352, 353.

The cross-sectional shape of the support shaft 314 is a shape other than a circle to restrict the slider 330 from moving only in the axial direction of the support shaft 314. In detail, in order to avoid the slider 330 from rotating around the support shaft 314 with the support shaft 314 as a rotation axis, the support shaft 314 may be provided in a shape other than a circle, such as an oval, a polygon, a keyhole, a square, a triangle, and the like. Fig. 4 is a top view of fig. 2, with the top cover plate omitted from fig. 4. Referring to fig. 4, the supporting shaft 314 of the present embodiment is shaped like a keyhole, and is a combination of a substantially circular shape and a substantially rectangular shape, wherein the rectangular portion protrudes from the circular shape.

With continued reference to fig. 2 and 3, in addition, the lifting assembly 300 further includes a top cover plate 370 fixed on the top of the sleeve holder 310, wherein the top cover plate 370 is used for limiting the second sleeve 320 to only rotate relative to the first sleeve 316, and simultaneously limiting the stroke of the sliding member 330 moving along the axial direction of the supporting shaft 314. In this way, the sliding member 330 is prevented from moving to protrude out of the first sleeve 316.

Fig. 5A and 5B are schematic diagrams illustrating the electronic device adjusting the height through the lifting assembly. Referring to fig. 3, fig. 5A and fig. 5B, when the user wants to adjust the height of the electronic device 400, the sleeve portion 324 or the turntable portion 326 of the second sleeve 320 is rotated by hand, wherein the area of the turntable portion 326 is large, so that the user can conveniently apply force to adjust the height of the electronic device 400 by rotating the turntable portion 326, and the user can save labor relative to rotating the sleeve portion 324.

For the present embodiment, the sliding block 334 is fixed at the first position P1 in the spiral sliding groove 322, and the electronic device 400 is fixed at the predetermined first height D1 (as shown in fig. 5A) through force balance, at this time, the elastic restoring force of the elastic element 350 and the gravity caused by the weight of the electronic device 400 obtain the force balance.

When a user wants to adjust the height of the electronic device 400, the user touches and rotates the turntable 326, and the sleeve portion 324 of the second sleeve 320 is rotated by the turntable 326, the slider 334 of the slider 330 changes its position in the spiral sliding slot 322, and the third sleeve 332 of the slider 330 rotates relative to the sleeve portion 324 of the second sleeve 320 along with the movement of the slider 334.

Specifically, when the user rotates the turntable unit 326 clockwise, the slider 334 is pushed by the lower groove wall of the spiral sliding groove 322 to move upward, and at this time, the released elastic restoring force of the originally compressed elastic element 350 pushes the third sleeve 332 upward from the inside of the sleeve portion 324 of the third sleeve 332, so that the slider 334 is pushed by the lower groove wall of the spiral sliding groove 322 and the elastic element 350 to move upward along the track of the spiral sliding groove 322.

After the user stops rotating the turntable portion 326, the slider 334 moves to a second position P2 in the spiral chute 322, and the electronic device 400 is fixed at a second height D2 (as shown in fig. 5B) by the gravity caused by the weight of the electronic device 400 and the elastic restoring force of the elastic element 350 achieving a force balance.

Particularly, when the slider 334 moves upward along the spiral chute 322 in the spiral chute 322, because the elastic element 350 is a whole composed of a plurality of elastic elements 351, 352, 353 with different elastic coefficients, and the elastic elements 351, 352, 353 are separated from each other by the sliding elastic piece 360, when the force pressing the elastic elements 350 is gradually released, the elastic restoring forces provided by the elastic elements 351, 352, 353 with different elastic coefficients are different, and the deformation degrees are different, so that the third sleeve 332 pushed upward by the elastic elements 351 drives the slider 334 to move upward smoothly in the spiral chute 322.

More specifically, the elastic elements 353, 352 and 351 are arranged such that the elastic coefficients thereof are vertically arranged from bottom to top, and when the elastic elements 350 are compressed, the elastic elements 351 having the smallest elastic coefficients are compressed.

The sliding elastic sheet 360 disposed between the two adjacent elastic elements 351, 352, 353 provides an abutting surface for the elastic elements 351, 352, 353, so as to prevent the elastic elements 351, 352, 353 from being compressed or released to be dislocated due to force, thereby affecting the normal operation of the lifting assembly 300.

Conversely, when the electronic device 400 is fixed at the second height D2 (as shown in fig. 5B), the user can rotate the rotating disc 326 counterclockwise to move the sliding block 334 from the second position P2 to the first position P1 in the spiral sliding groove 322, so that the electronic device 400 comes to the first height D1 (as shown in fig. 5A) with the downward movement of the sliding block 334.

When the slider 334 moves downward along the spiral chute 322 in the spiral chute 322, the elastic elements 351, 352, and 353 with different elastic coefficients are first deformed by the elastic element 351 with the smallest elastic coefficient after being stressed, and the third sleeve 332, which is forced to push upward by the elastic elements 351, 352, and 353 with different elastic coefficients, helps to drive the slider 334 to move downward smoothly in the spiral chute 322 by the elastic elements 351, 352, and 353 with different degrees of compression deformation provided by the elastic elements 351, 352, and 353 with different elastic coefficients.

In summary, the lifting assembly of the present invention achieves a force balance by the supporting force of the elastic element, the weight of the electronic device and the spiral chute of the second sleeve, so that when the rotating disc portion is rotated by the hand of the user, the elastic element releases the elastic restoring force to make the slider ascend along the spiral chute; on the contrary, when the turntable part rotates reversely, the sliding block presses the elastic element downwards along the spiral chute, the elastic element is pressed to descend, and the balance is achieved through the weight of the electronic device, the supporting force of the elastic element and the limitation of the spiral chute, so that the electronic device is fixed at the required height. Therefore, for a user, the lifting assembly can be operated in a labor-saving operation mode.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
