Lifting mechanism and support

Technical Field

The application relates to the technical field of supports, in particular to a lifting mechanism and a support.

Background

In the prior art, when the support adopts a sleeve type lifting mode, the space in the sleeve is limited.

The lifting mechanism 100 of the present embodiment includes a covering member 110, a packing member 140, a lifting member 160, a first slide rail assembly 170, a second slide rail assembly 180, a seat member 200, a first constant force spring 310 and a second constant force spring 320. The structure, connection relationship, and operation principle of the aforementioned components included in the lifting mechanism 100 will be described in detail below with reference to fig. 1 to 10.

Before describing the lifting mechanism 100, please first refer to fig. 1, which illustrates an example of a bracket to which the lifting mechanism 100 is applied. In order to make the operation of the lifting mechanism 100 more clear, the structure and operation of the bracket will be described first. As shown in fig. 1, in the example shown in fig. 1, the lifting mechanism 100 is not shown but is covered by a first housing 510, and further, a second housing 520 is provided outside the first housing 510. Wherein, the support comprises a connecting mechanism 400 and a chassis mechanism 600, the connecting mechanism 400 comprises a rib plate 410 connected with the lifting mechanism 100, a hinge 420 connected with the rib plate 410 and a connecting component 430 connected with the hinge 420, and the working processes of the structures included in the connecting mechanism 400 will be emphasized when the support is described again below. On this basis, the chassis mechanism 600 is disposed below the elevating mechanism 100 to ensure that the stand is stably erected on a horizontal plane.

With further reference to fig. 2, fig. 2 shows a schematic view of an isometric view of the assembly of the cross brace 410 and the elevator mechanism 100. In an embodiment, the rib plate 410 includes two rib portions disposed opposite to each other and connecting portions connected to the two rib portions, respectively, and the elevation member 160 of the elevation mechanism 100 is connected to the connecting portions by a fastener, such as a screw. A specific structure of the elevation member 160 is not shown in fig. 2 due to the shielding of the connection portion, and for this reason, the specific structure of the elevation structure will be described later in the description of fig. 3 to 8. Still referring to fig. 2, the elevating mechanism 100 includes a cover 110 disposed at the outside and formed in a cylindrical shape, and an elevating member 160, which will be described below, is disposed in the cover 110, and when the elevating member 160 is elevated based on the state shown in fig. 2, a portion of the elevating member 160 will be exposed with respect to the cover 110, thus forming a "sleeve-type" elevating process.

Referring to fig. 3, fig. 3 omits the above-described rib 410 and the screw connecting the rib 410 and the elevation member 160 on the basis of fig. 2, and the upper end of the elevation member 160 is exposed therefrom, and here, further referring to fig. 4, fig. 4 shows an enlarged view of a point a in fig. 3, which shows the structure of the upper end of the elevation member 160 in detail.

To describe the structure of the lifting member 160 more precisely, as mentioned above in conjunction with fig. 1, the connection mechanism 400 includes a connection assembly 430, and in an embodiment, the connection assembly 430 is used to support a supported object, such as a monitor, so the orientation of the monitor is defined as "front" and the orientation of the lifting mechanism 100 is defined as "rear". As such, and with particular reference to fig. 4, in particular, fig. 4 illustrates an upper end surface of the elevation member 160, and as an alternative, the elevation member 160 may have a cross-section that is the same shape as the upper end surface.

In an embodiment, the elevation member 160 may be formed in a bar shape and extend in a vertical direction. The elevation member 160 includes a first elevation part 161 and a second elevation part 162 which are connected to each other and are offset from each other in a direction perpendicular to the front-rear direction, which will be described in detail in the following description of fig. 7 and 8, and will be described only briefly to assist in the description of fig. 4. Still referring to fig. 4, in an embodiment, the packing member 140 between the lifting member 160 and the packing member 110 may be disposed at an inner side portion of the upper end of the packing member 110, in other words, the packing member 140 is disposed at an outer side portion of the lifting member 160, and the packing member 110 is disposed at an outer side portion of the packing member 140 and the packing member is disposed at the upper end of the packing member 110.

As shown in fig. 4, the tightening member 140 is coupled to the wrapping member 110 by a first coupling screw 150. Further, the covering member 110 is further provided with a set screw 120, the set screw 120 is matched with an internal threaded hole formed in the covering member 110, when the set screw 120 is screwed to the inside of the covering member 110, the set screw 120 will abut against or further abut against the urging member 140, so that the urging member 140 urges or further urges the elevation member 160, thereby providing a friction force for the elevation member 160 during the elevation process, and as an example, the urging member 140 may be formed of POM (Polyoxymethylene/poly-oxymethylene, Polyoxymethylene resin). It is understood that the aforementioned frictional force is adjusted by screwing the set screw 120 to meet the use requirements of different occasions, and two set screws 120 may be provided, one set screw 120 shown in fig. 4 increasing the frictional force between the first elevating portion 161 and the packing member 140, and the other set screw 120 increasing the frictional force between the second elevating portion 162 and the packing member 140 in the same manner on the side not shown. Also shown in fig. 4 is a stationary rail screw 130, the stationary rail screw 130 being used to connect the cladding 110 to a stationary rail as will be described later.

Referring to fig. 5, the covering member 110 is omitted from fig. 5 relative to fig. 4, such that one of the rail assemblies for accomplishing the elevation of the elevation member 160, i.e., the second rail assembly 180, is shown in fig. 5. Before describing the slide rail assembly, however, with further reference to fig. 6 herein, fig. 6 shows a schematic view of an enlarged view at B in fig. 5, which can be combined with the above description to further clarify the installation of the set screw 120, the stationary rail screw 130, and the first connection screw 150.

On this basis, the structure of the lifting member 160 and the arrangement of the slide rail assembly will be further described below. Referring to fig. 7, the urging member 140 is omitted from fig. 7 with respect to fig. 5, and is a plan view. As mentioned in the above description, the elevation member 160 includes the first elevation part 161 and the second elevation part 162 which are connected to each other and are shifted from each other in a direction perpendicular to the front-rear direction (the left-right direction in the orientation of fig. 7), for example, the first elevation part 161 is shifted to the left side with respect to the first elevation part 161 in the example given in fig. 7.

With further reference to fig. 7, for one lift, such as the first lift 161, it may be formed as a hollow structure and may have a cross-section with a generally rectangular outer profile. On this basis, the first lifting portion 161 is engaged with the first slide rail assembly 170, and the second lifting portion 162 is engaged with the second slide rail assembly 180, which may be the same, for example, the first slide rail assembly 170 and the second slide rail assembly 180 may have the same structure, and therefore, the first slide rail assembly 170 will be described as an example in the following description.

As shown in fig. 7, which may be combined with fig. 9 and 10 (fig. 9 shows a schematic view of an axonometric view of a part of the members of the elevator mechanism 100 further omitted from fig. 7, and fig. 10 shows a schematic view of an enlarged view at C in fig. 9), the first slide rail assembly 170 includes a first stationary rail 171, a first movable rail 172, a ball member 173, and a first holder 174. Wherein the first stationary rail 171 has a length smaller than that of the first movable rail 172, which may be disposed below the first elevating portion 161 via a plurality of second coupling screws 190 (the second coupling screws 190 are not shown in fig. 7, which are particularly shown in fig. 10). The first stationary rail 171 and the first movable rail 172 may each have a substantially U-shaped cross section, and two rows of vertically arranged ball members 173 held by the holder are respectively disposed therebetween, so that the first elevating portion 161 and the first movable rail 172 are elevated with respect to the first stationary rail 171. Similarly, the second lifting portion 162 and the second movable rail are also lifted relative to the second stationary rail in this manner (the second movable rail and the second stationary rail are not labeled).

Based on the above-described features, still referring to fig. 7, the first stationary rail 171 of the first slide rail assembly 170 is disposed at the right side of the first lifting portion 161, which enables the first slide rail assembly 170 to be disposed at the right side of the first lifting portion 161, and similarly, the second slide rail assembly 180 is disposed at the left side of the second lifting portion 162. In this way, the space left by the first raised/lowered part 161 being displaced with respect to the second raised/lowered part 162 is occupied by the first rail assembly 170, and the space left by the second raised/lowered part 162 being displaced with respect to the first raised/lowered part 161 is occupied by the second rail assembly 180, which ensures rational arrangement of the inner side portion raising/lowering member 160, the first rail assembly 170, and the second rail assembly 180 of the wrapping member 110 having a limited space, for example, a rectangular parallelepiped shape, in other words, further makes the arrangement of the three raising/lowering member 160, the first rail assembly 170, and the second rail assembly 180 compact.

In the embodiment, the first and second slide rail assemblies 170 and 180 are arranged in a compact manner, and are arranged in a staggered manner in the front-back direction and in an asymmetric manner, so that the structural strength of the lifting member 160 can be maintained to the greatest extent, and the occurrence of jamming in the lifting process is avoided. Further, in an embodiment, two rows of ball members 173 included in each slide rail assembly may be spaced apart in the front-to-rear direction, which further facilitates increasing the smoothness of movement of the lifting member 160.

Referring further to fig. 8, fig. 8 omits the urging member 140 relative to fig. 5 and shows a bottom view. Referring to fig. 8, the seating member 200 is connected with the elevation member 160 via a third connection screw 210 and disposed below the elevation member 160, and the cross-section of the seating member 200 may have substantially the same outer profile as the cross-section of the elevation member 160, i.e., the seating member 200 may have the same structure as the elevation member 160 with a misalignment. Further, a first constant force spring 310 and a second constant force spring 320 are respectively disposed below the seat member 200 corresponding to the first elevating portion 161, and a distal end of each constant force spring may be connected to the covering member 110, so that when the elevating member 160 ascends with respect to the covering member 110, the two constant force springs provide a pulling force to the elevating member 160. Therefore, it can be understood that the first constant force spring 310 and the second constant force spring 320 are also disposed in a staggered manner in the front-rear direction, which avoids the increase in the size of the cover 110 and the seat member 200 when they are disposed side by side in the left-right direction.

The present embodiment also provides a stand including the above lifting mechanism 100, and further including the above-mentioned connecting mechanism 400 and chassis mechanism 600, here referring to fig. 1, the connecting mechanism 400 includes a connecting assembly 430 for connecting a supported object such as a display, and a hinge 420 is provided between the connecting assembly 430 and the cross brace 410 to allow the connecting assembly 430 to pivot with respect to the cross brace 410. In addition, the bracket also has the technical effects as described above, and the details are not repeated herein.

The above description is only a preferred embodiment of the present application, and not intended to limit the scope of the present application, and all changes that can be made in the details of the description and drawings, or directly/indirectly implemented in other related technical fields, are intended to be embraced therein without departing from the spirit of the present application.
