The control panel base 110, the elevating support 130 and the control assembly 160 of the elevating structure 1 are shown in fig. 1 (only the release handle and the elevating handle are visible in fig. 1, as will be described in detail below in connection with fig. 4-6). The control panel base 110 is a generally flat plate-like structure for supporting and securing the control panel 4, and in some embodiments is connected to or integrally formed with a display base for supporting and securing the display 3. One end of the lifting support device 130 is connected to the control panel base 110, and the other end is connected to the host computer 5. The control assembly 160 is used to control the elevating support device 130 to realize the elevation of the control panel base 110 and the control panel 4 (and thus the display 3) mounted thereon.

Fig. 2 and 3 show the base 120, the elevating support 130 and the control assembly release cable 162 in the elevating structure 1. The base 120 is adapted to be connected to a host 5 (see fig. 1), for example, to a housing or case of the main body 5. A Cable known as a Bowden Cable (Bowden Cable) may be used for the release Cable 162. The elevating supporting device 130 includes a first connecting seat 131 connected to the base 120, a second connecting seat 132 connected to the control panel base 110 (see fig. 4), and a first link 133, a second link 134, and a gas spring 135 connected between the first connecting seat 131 and the second connecting seat 132. In the embodiment shown in fig. 2 and 3, the first connecting seat 131 is integrally formed with the base 120, however, in other embodiments, the first connecting seat 131 and the base 120 may be two separate parts connected together by fastening means or connecting means such as screws, studs, welding, etc. The first end 136 of the first link 133 is rotatably connected to the first connecting seat 131, and the second end 137 is rotatably connected to the second connecting seat 132. The second link 134 has a first end 138 rotatably connected to the first connecting seat 131 and a second end 139 rotatably connected to the second connecting seat 132. The gas spring 135 has a first end 140 rotatably coupled to the first coupling seat 131 and a second end 141 rotatably coupled to the second coupling seat 132.

The first link 133 and the air spring 135 are rotatable about substantially the same axis with respect to the first connecting seat 131, and the first link 133 and the air spring 135 are rotatable about different axes (e.g., two substantially parallel axes) with respect to the second connecting seat 132. The second link 134 and the air spring 135 are rotatable about substantially the same axis with respect to the second connecting seat 132, and the second link 134 and the air spring 135 are rotatable about different axes (e.g., two substantially parallel axes) with respect to the first connecting seat 131.

In some embodiments, this can be achieved by connecting the first link 133 and the gas spring 135 to the first connecting seat 131 using the same pivot (in the illustrated embodiment, the pivot is in the form of a pin, but in other embodiments, it can be in other forms) or using two or more pivots having their axes substantially on the same line, and connecting the second link 134 and the gas spring 135 to the second connecting seat 132 using the same pivot or using two or more pivots having their axes substantially on the same line. In some embodiments, as shown in fig. 2 and 3, the first end 136 of the first link 133 and the first end 140 of the gas spring 135 are connected to the first connecting seat 131 by two opposite pivots 142 and 143 on the same line of the axis, and the second end 139 of the second link 134 and the second end 141 of the gas spring 135 are connected to the second connecting seat 132 by the same pivot 144. The second end 137 of the first link 133 is connected to the second connecting seat 132 through a pivot 145, and the first end 138 of the second link 134 is connected to the first connecting seat 131 through two opposite pivots 146 and 147 on the same line with the axis. In addition, one or more connecting elements or fixing elements may be further used for reinforcement or connection with other components, for example, a connecting element 148 such as a pin may be further used for reinforcing the first connecting seat 131, and for example, the elevating support device 130 may further include a housing 149 (see fig. 1) for accommodating the first connecting seat 131, the second connecting seat 132, the first link 133, and the second link 134, and the housing 149 may also be fixed with the first connecting seat 131 and the second connecting seat 132 by a connecting element such as a pin, a bolt, and the like.

In some embodiments, the first link 133 is substantially parallel to the second link 134 and is located below the second link 134. In some embodiments, the first connecting seat 131, the second connecting seat 132, the first link 133, and the second link 134 form a parallel four-bar linkage, and the gas spring 135 extends along a diagonal position of the parallel four-bar linkage, i.e., the gas spring 135 connects the first end 136 of the first link 133 and the second end 139 of the second link 134 to some extent. In case that a release switch 150 (described in detail below) of the gas spring 135 is turned on, the parallel four-bar linkage structure may be rotated so that the control panel base 110 connected to the second connection seat 132 is raised or lowered.

Although two

links

133 and 134 are used in this embodiment, it should be understood that in other embodiments, only one link may be used to implement the lifting mechanism. For example, in some cases, the second link 134 shown in fig. 2 and 3 may be removed while leaving the first link 133 and the gas spring 135, or the first link 133 shown in fig. 2 and 3 may be removed while leaving the second link 134 and the gas spring 135.

The release switch 150 of the gas spring 135 includes a valve 151 on the gas spring 135 and a valve pull 152 connected to one end 153 of a control assembly release cable 162. The valve stem 152 controls the extension and retraction of the gas spring 135. In some embodiments, as shown in FIG. 3, the valve 151 is located near the first end 140 of the gas spring 135.

The other end of the control assembly release cable 162 (remote from the valve stem 152) is connected to other components of the control assembly mounted on the control panel base to effect control of the valve stem 152. The control assembly 160 and its assembly on the control panel base 110 will be described below with reference to fig. 4-6. As shown in fig. 4-6, the control assembly 160 includes a rotating shaft 161, which is rotatably disposed on the control panel base 110. The rotation shaft 161 has a rotation axis 165 substantially parallel to the control panel base 110, and is rotatable about the rotation axis 165. In some embodiments, the axis of rotation is a linear axis of rotation that is substantially parallel to the control panel base 110. An end 163 of the release cable 162 remote from the valve lever 152 is connected to the shaft 161. The control assembly 160 further includes a release handle 164 coupled to the shaft 161, wherein operation (e.g., rotation) of the release handle 164 causes the shaft 161 to rotate about its own axis 165, thereby actuating a release cable 162 coupled to the shaft 161 to control the release switch 150 to open or close. When the release switch 150 is opened, the valve pulling rod 152 is pulled out from the gas spring valve 151, and the gas spring 135 can continuously extend and retract along the axial direction; when the release switch 150 is closed, the valve stem 152 is not pulled out of the gas spring valve 151, and the gas spring 135 is locked.

In some embodiments, the hinge 161 is mounted to the control panel base 110 via a bracket 166. In some embodiments, the bracket 166 has a base plate 167 and

parallel flanges

168 and 169 extending upwardly from the base plate 167, the

flanges

168 and 169 being spaced apart in the axial direction of the shaft 161, and the

flanges

168 and 169 each having a mounting hole, thereby providing two opposing mounting holes spaced apart in the direction of the rotational axis 165 of the shaft 161 (in other embodiments, more than two mounting holes may be provided). The bottom plate 167 of the bracket 166 is fixed to the control panel base 110 by a screw or the like, and the rotary shaft 161 is inserted into mounting holes provided in the

flanges

168 and 169, respectively, and is rotatably mounted to the bracket 166. Bearings and/or elastic members may be provided at or near the position where the rotating shaft 161 meets the bracket 166 to make the rotation of the rotating shaft 161 more smooth. In some embodiments, as shown in fig. 4-6, a flute-type leaf spring 170 and 171 for limiting the position of the rotation shaft 161 is provided at the position where it meets the inner side of the

flanges

168 and 169, and a

bearing

172 and 173 is provided at the position where the rotation shaft 161 meets the

flanges

168 and 169.

In some embodiments, the release handle 164 and the release cable 162 are coupled to the shaft 161 at different locations in the direction of the axis of rotation 165. In some embodiments, the release handle 164 and the release cable 162 are respectively mounted on the rotating shaft 161 at two sides of the bracket 166, specifically, the release handle 164 is mounted on the rotating shaft 161 at a first side of the bracket 166, and the release cable 162 is mounted on the rotating shaft 161 at a second side of the bracket 166.

In some embodiments, the mounting end 174 of the release handle 164 is formed with a hole for receiving the axial first end 175 of the shaft 161, and the release handle 164 is secured to the first end 175 of the shaft 161 by inserting the axial first end 175 of the shaft 161 into the hole of the mounting end 174 and securing the mounting end 174 to the shaft end 175 received in the mounting end 174 with a securing device such as a screw.

In some embodiments, the control assembly 160 further includes a reset element 176 for resetting the shaft 161. In some embodiments, the restoring element 176 is a coil spring, one end of which is connected to the control panel base 110 and the other end of which is connected to the rotating shaft 161, for example, the second end 177 (the end away from the first end 174) of the rotating shaft 161.

In some embodiments, the reset element 176 and the release cable 162 are coupled to the shaft 161 by a shaft linkage 178. In some embodiments, the shaft linkage 178 is a sleeve member disposed on the rotating shaft 161, the sleeve member 178 is disposed on and fixed to the outer peripheral surface of the rotating shaft 161 near the second end 177 thereof, and the reset member 176 and the release cable 162 are respectively connected to the sleeve member 178. In particular embodiments, the sleeve member 178 is provided with a mounting portion 179 extending downwardly from an outer peripheral surface thereof, and at least one of the reset element 176 and the release cable 162 is coupled to the mounting portion 179. In particular, the reset element 176 and the release cable 162 are both connected to the mounting portion 179 such that the connection position of the reset element 176 and/or the release cable 162 to the rotary shaft 161 (specifically the sleeve member 178, more specifically the mounting portion 179) (in the inoperative state, i.e., when the rotary shaft 161 has not yet rotated) is moved down to a position lower than the axis of rotation of the rotary shaft 161, more specifically, lower than the bottom portion of the outer peripheral surface of the rotary shaft 161 itself.

In some embodiments, the connection between the reset element 176 and the rotating shaft 161 and the connection between the release handle 164 and the rotating shaft 161 are located on two sides of the connection between the release cable 162 and the rotating shaft 161 in the axial direction of the rotating shaft 161. In some embodiments, the release handle 164 is coupled to the shaft 161 at the first end 175 thereof, the reset member 176 is coupled to the shaft 161 at the second end 177 thereof, and the release cable 162 is coupled to the shaft 161 proximate the second end 177 thereof. In particular embodiments, the reset element 176 and the release cable 162 are coupled such that: when the release handle 164 is operated to rotate the rotary shaft 161 about its rotational axis, the reset element 176 and the release cable 162 apply a force to the rotary shaft 161 in a generally parallel direction.

In some embodiments, to better hold the release cable 162 in place during use, one or more flaps 180 may also be provided that overlie a segment of the release cable 162. As shown in fig. 5 and 6, a cover sheet 180 may be provided at least at a position near one end of the release cable 162 connected to the rotation shaft 161. The cover sheet 180 is fixed to the control panel base 110 by screws or the like, and a space allowing the release cable 162 to pass is formed between the cover sheet 180 and the control panel base 110. As for the above-described manner of driving the release cable 162 by rotating the rotation shaft 161, the cover sheet 180 is particularly effective in preventing the release cable 162 from being lifted up in the vicinity of the connection with the rotation shaft 161.

The connection between the release handle 164 and the release cable 162 is simple and efficient by the way of the rotation shaft 161, and the release switch 150 can be controlled by operating the release cable 162 with a small force. And the lifting operation with easy labor saving and soft operation feeling can be realized by calculating and accurately designing the force value in the gas spring.

In some embodiments, as shown in fig. 1, the control assembly 160 further includes a lift handle 181 connected to the control panel base 110, which is operable to control the lift support 130 to effect raising and/or lowering of the control panel base 110 relative to the base 120 (see fig. 2) or the host 5 when the release switch 150 is opened.

In some embodiments, at least a portion of lift handle 181 is disposed adjacent to release handle 164 to enable simultaneous operation of lift handle 181 and release handle 164 with a single hand to control movement of lift support 130. The lift handle and the release handle are located near the same corner of the control panel base, e.g., both are located near the corner to the right of the outside of the control panel base. In some embodiments, the lifting handle 181 is a handle frame extending outward and slightly obliquely downward along the outer edge of the control panel base 110 facing the operator, and the release handle 164 is located below one side edge (e.g., the right side edge) of the handle frame, and in the non-operating state, the side edges of the handle frame and the release handle 164 extend divergently like a pincer handle (connected or close to each other at one end and separated from each other at the other end), so that the user can hold and apply force to each other with a single hand at the same time, and the operation is easy.

In use, the lifting structure 1 can be operated in a very simple and labour-saving manner. In one embodiment, the release handle 164 and the lift handle 181 may be operated with a single hand, for example, by grasping the release handle 164 and the lift handle 181 with one hand and applying a force to the release handle 164 and the lift handle 181, such that the release handle 164 drives the release cable 162 to open the release switch 150, and at the same time, the lift handle 181 rotates the lift support 130 to achieve the lifting of the control panel base 11.

The above specific embodiments are provided so that the present disclosure will be thorough and complete, and the present invention is not limited to these specific embodiments. It will be understood by those skilled in the art that various changes, substitutions of equivalents, and alterations can be made herein without departing from the spirit of the invention and are intended to be within the scope of the invention.
