Description

Technical Field

[0001] The present application relates to the technical field of bracket connection of terminal equipment, and in particular to a lifting structure. Background Art

[0002] Terminal devices such as desk lamps and monitors are usually supported and fixed by brackets. In order to adapt these terminal devices to the needs of different users or the needs of the same user in different scenarios, the supporting brackets are usually designed as lifting structures, thereby achieving tilt, rotation and vertical height adjustment.

[0003] In the prior art, the terminal device is usually adjustable and fixed by bolts or clamping. For example, bolts are set on the side of the terminal device bracket, and after the user adjusts the terminal device to a suitable position, the bolts are used to tighten it. This will cause the user to adjust the terminal device inconveniently. Another technical route in the prior art is to use the friction provided by the pivoting part to achieve the fixation between different components, such as the pivoting part between the terminal device and the bracket, and the pivoting part between different sections of the bracket. After the user adjusts to the appropriate position, these pivoting parts use static friction to make the two pivoted parts relatively fixed. For this method, on the one hand, the user needs to apply a force greater than the static friction force to achieve position adjustment, which makes the user more laborious; on the other hand, as the parts of the pivoting part loosen, the static friction force is easily reduced, resulting in the inability to relatively fix the two pivoted parts.

[0004] Therefore, how to adjust the terminal equipment conveniently, reliably and labor-savingly has become a technical problem that needs to be solved urgently.

[0005] The above contents are only used to assist in understanding the technical solutions of the utility model and do not constitute an admission that the above contents are prior art. Utility Model Content

[0045] In order to conveniently adjust the terminal device, the utility model embodiment discloses a lifting structure, please refer to Figure 1 , Figure 1The three-dimensional structure diagram of a lifting structure disclosed in this embodiment includes: a base 1, a support rod 2, a linkage rod mechanism 3, a fixed seat 4 and a transmission mechanism, wherein the transmission mechanism includes an elastic module 5 and a transmission module 6, wherein:

[0046] The base 1 is placed on the table to support the entire lifting structure.

[0047] Please refer to Figure 1 and Figure 2 , Figure 2 This is a schematic diagram of the coordination structure of a support rod and a linkage rod mechanism disclosed in this embodiment. The support rod 2 is composed of two side rods 21 and a top rod 22 to form a support structure. Specifically, the two side rods 21 and the top rod 22 form an inverted concave structure, and the two side rods 21 are fixedly arranged on the top of the base 1. In a specific embodiment, the two side rods 21 and the top rod 22 can be assembled separately or integrally formed. The support rod 2 mainly supports the linkage rod mechanism 3, the elastic module 5 and the transmission module 6, and raises the fixed seat 4 to raise the terminal device to a sufficient height. In this embodiment, the terminal device can be a light source of a desk lamp, or a display, etc.

[0048] Please refer to Figure 1 and Figure 2 , the first connection part 31 of the linkage rod mechanism 3 is pivoted on the two side rods 21, and is closer to the top rod 22 relative to the base 1; the second connection part 32 of the linkage rod mechanism 3 is connected to the fixed seat 4. Specifically, the pivot position of the first connection part 31 can be determined based on experience, mainly considering the center of gravity and stability issues, that is, after the terminal device is installed on the fixed seat 4, the center of gravity is stable enough and not prone to tipping. Of course, in the specific implementation process, the center of gravity stability can also be ensured by increasing the mass of the base 1. The second connection part 32 and the fixed seat 4 can be detachably connected or fixedly connected. In this embodiment, the first connection part 31 is pivoted on the two side rods 21, so that the linkage rod mechanism 3 can rotate around the pivot point as a whole.

[0049] In this embodiment, the transmission mechanism is provided with an elastic module 5 and a transmission module 6. Figure 1 and Figure 3 , Figure 3This is a schematic diagram of the assembly structure of an elastic module 5 and a transmission module 6 disclosed in this embodiment, one end of the transmission mechanism is fixedly connected to the fixed seat 4, and the other end is connected to the side rod 21, and the transmission mechanism can rotate relative to the side rod 21; one end of the transmission module 6 abuts against the elastic module 5, and the other end of the transmission module 6 is rotationally connected to the side rod 21; the top of the elastic module 5 is connected to the bottom end of the fixed seat 4. In a specific embodiment, the elastic module 5 can be fixed to the fixed seat 4 by threads, or by means of clamping. In the specific implementation process, when the transmission mechanism rotates downward relative to the support rod 2, the transmission module 6 compresses the elastic module 5 to store elastic potential energy; when the transmission mechanism rotates upward relative to the support rod 2, the elastic module 5 releases the stored elastic potential energy to assist the transmission mechanism in rotating.

[0050] Specifically, the elastic module 5 is fixed at the bottom end of the fixed seat 4, and when the user adjusts the height position, energy conversion can be performed to achieve position adjustment. Specifically, when the user moves the fixed seat 4 downward, the fixed seat 4 will compress the elastic module 5. At this time, the gravitational potential energy reduced by the fixed seat 4 and the downward movement will be converted into the elastic potential energy of the elastic module 5 and stored in the elastic module 5, that is, the elastic potential energy stored in the elastic module 5 is equal to the gravitational potential energy lost by the fixed seat 4 moving downward; when the user moves the fixed seat 4 upward, the elastic potential energy stored in the elastic module 5 is released and converted into the gravitational potential energy increased by the fixed seat 4 and the upward movement, that is, the elastic potential energy released by the elastic module 5 is equal to the gravitational potential energy increased by the fixed seat 4 moving upward. In this embodiment, by storing and releasing the elastic potential energy by the elastic module 5, the user can be provided with downward or upward energy support when moving the fixed seat 4 downward or upward, thereby saving the force applied by the user and facilitating the user to adjust the position of the fixed seat 4.

[0051] Please refer to Figure 3 , Figure 4 and Figure 5 , Figure 4 is a schematic diagram of a three-dimensional structure of a transmission module disclosed in this embodiment, Figure 5 Schematic diagram of a cross-sectional structure of a transmission module disclosed in this embodiment. The transmission module 6 includes: a top wheel 60, a first rolling wheel 61, a second rolling wheel 62 and a follower connecting rod 63, wherein:

[0052] The rotating shaft of the first rolling wheel 61 is rotatably connected to the elastic module 5 , specifically, can be connected to the inner wall of the elastic module 5 , so that the rotating shaft of the first rolling wheel 61 moves following the movement of the elastic module 5 , thereby making the first rolling wheel 61 always keep adapting to the elastic module 5 .

[0053] The top wheel 60 is fixedly connected to the rotating shaft of the first rolling wheel 61 through the follower connecting rod 63, and the top wheel 60 cooperates to abut the bottom end of the elastic module 5. In this embodiment, when the rotating shaft of the first rolling wheel 61 rotates, the top wheel 60, the follower connecting rod 63 and the first rolling wheel 61 rotate accordingly, thereby converting the translation of the fixed seat 4 and the elastic module 5 into rotation. The top wheel 60 is fixedly connected to the rotating shaft of the first rolling wheel 61 through the follower connecting rod, and cooperates to abut the bottom end of the elastic module 5, so that the moving direction of the elastic module 5 can be positioned and the elastic module can be supported. When the elastic module 5 moves up and down, the momentum in the horizontal direction can be decomposed by the top wheel 60, so that on the one hand, it can ensure that the elastic module 5 does not rotate, and on the other hand, the friction of the elastic module 5 can be reduced by the top wheel 60, thereby reducing the force required to be applied by the user.

[0054] The second rolling wheel 62 and the first rolling wheel 61 are in rolling contact with each other, and the rotation axis of the second rolling wheel 62 is connected to the inner wall of the support rod 2. In one embodiment, the rotation axis of the second rolling wheel 62 is fixedly connected to the inner wall of the support rod 2, and the second rolling wheel 62 can rotate relative to its rotation axis, that is, the rotation axis of the second rolling wheel 62 is fixed; in another embodiment, the rotation axis of the second rolling wheel 62 is rotationally connected to the inner wall of the support rod 2, and the second rolling wheel 62 is fixed relative to its rotation axis, that is, the rotation axis of the second rolling wheel 62 rotates.

[0055] The second rolling wheel 62 and the first rolling wheel 61 are in rolling contact, and the rotating shaft of the second rolling wheel 62 is rotatably connected to the inner wall of the support rod 2. In a specific embodiment, the rotating shaft of the second rolling wheel 62 and the rotating shaft of the first rolling wheel 61 are connected to different objects. The rotating shaft of the first rolling wheel 61 is connected to the inner wall of the elastic module 5, so that the rotating shaft of the first rolling wheel 61 moves with the movement of the elastic module 5; while the rotating shaft of the second rolling wheel 62 is connected to the inner wall of the support rod 2, that is, the rotating shaft of the second rolling wheel 62 will not move horizontally, thereby limiting the horizontal movement direction of the elastic module 5. In this embodiment, by having the rotating shaft of the second rolling wheel 62 and the rotating shaft of the first rolling wheel 61, one is fixed and the other is moving, it is achieved that the up and down movement of the fixed seat 4 can be converted into rotation, and the horizontal movement of the fixed seat 4 can be limited, so that the direction of the terminal device (for example, the irradiation direction of the light source) is not easy to change.

[0056] In one embodiment, the first rolling wheel 61 and the second rolling wheel 62 are gears, and the second rolling wheel 62 and the first rolling wheel 61 are meshed and rolled; in another embodiment, the first rolling wheel 61 and the second rolling wheel 62 are cams, and the second rolling wheel 62 and the first rolling wheel 61 are meshed and rolled; in the third embodiment, the first rolling wheel 61 and the second rolling wheel 62 are rollers, and the second rolling wheel 62 and the first rolling wheel 61 are in rolling friction contact. The first rolling wheel 61 and the second rolling wheel 62 are preferably gears, so as to facilitate the transmission between the first rolling wheel 61 and the second rolling wheel 62.

[0057] To further ensure that the fixing base 4 does not rotate but moves up and down in parallel, in a specific embodiment, please refer to Figure 2 The linkage rod mechanism 3 is a four-link structure, one end of the four links respectively cooperates with their respective pivot shafts to form a first connection part 31, which is respectively pivoted to the two side rods 21; the other ends of the four links respectively cooperate with their respective connection shafts to form a second connection part 32, which is respectively connected to the fixed seat 4; and each of the four links is arranged parallel to each other. Specifically, one end of the four links, that is, the first connection part 31, is respectively pivoted to the two side rods 21, so that the fixed seat 4 can rotate through the pivot of the first connection part 31 during the up and down movement. The second connection part 32 can be fixedly connected to the fixed seat 4, or it can be rotatably connected to the fixed seat 4. When the rotation connection is made, it can provide the fixed seat 4 with a degree of freedom of movement, so that the user can adjust the position of the fixed seat 4.

[0058] In order to improve the user's feel during adjustment, in an optional embodiment, the linkage rod mechanism 3 further includes a damping plate 33, see Figure 2 The damping plate 33 is arranged at least at one end of the first connecting part 31, and one end of at least one of the four connecting rods is pivotally connected to the side rod 21 through the damping plate 33. In the specific implementation process, the damping plates can be arranged in pairs, respectively arranged at both ends of the pivot axis. In this embodiment, by arranging the damping plate 33 at at least one end of the first connecting part 31, the user can adjust more smoothly, thereby improving the user's hand feeling.

[0059] In the specific embodiment, please refer to Figure 2 and Figure 3 The transmission module 6 is located inside the space enclosed by the four-bar structure, and the rotation axis of the second rolling wheel 62 also passes through the shell of the elastic module 5 to limit the translation of the elastic module 5 relative to the support rod 2. Thus, the entire lifting structure can be made compact, and the transmission module 6 can be protected by the four-bar structure to prevent the transmission module 6 from being touched unexpectedly.

[0060] In order to make the fixing seat 4 move smoothly, in an optional embodiment, please refer to Figure 3 , Figure 4 and Figure 5 The top wheel 60 is a rubber-coated roller, which is connected to the inside of the follower link 63 through the roller shaft. The rubber-coated roller rotates through the roller shaft, and the rubber-coated roller follows the follower link 63 to revolve around the rotation axis of the first rolling wheel 61. In this embodiment, the rubber-coated roller rotates through the roller shaft, which can convert the fixed seat 4 into the rotation of the rubber-coated roller under the action of friction during the translation process, thereby decomposing the rotation of the fixed seat 4, so that the direction of the terminal device on the fixed seat 4 (for example, the irradiation direction of the light source) is not easy to change; the rubber-coated roller follows the follower link 63 to revolve around the rotation axis of the first rolling wheel 61, which can make the fixed seat 4 and the elastic module 5 move up and down as a whole, thereby realizing the up and down position adjustment on the fixed seat 4.

[0061] In a specific embodiment, the elastic module 5 includes: a spring 51 and a spring seat 52, one end of the spring 51 is the top of the elastic module 5, and the other end of the spring 51 abuts against the spring seat 52; the spring seat 52 is the bottom of the elastic module 5. The spring seat 52 is slidably connected to the housing of the elastic module 5 through a sliding shaft, thereby achieving the fixing of the elastic module 5.

[0062] In the specific embodiment, please refer to Figure 4 and Figure 6 , Figure 6 Schematic diagram of an elastic module explosion structure disclosed in this embodiment, a columnar clamping portion 53 is provided on the top of the spring seat 52, and the other end is sleeved on the outer wall of the columnar clamping portion 53. In this embodiment, the spring 51 is sleeved by the columnar clamping portion 53, and the spring 51 can be directly positioned and fixed, that is, only the spring 51 needs to be sleeved on the columnar clamping portion 53 to fix the spring seat 52 and the spring 51 can be directly fixed, which facilitates the positioning and installation of the spring and improves the fixing efficiency.

[0063] In the specific embodiment, please refer to Figure 3 and Figure 4 There are two springs 51 arranged side by side; there are two columnar clamping parts 53 arranged side by side on the top of the spring seat 52, corresponding to the springs 51 one by one. In this embodiment, the two springs 51 arranged side by side are pulled against each other in the horizontal direction, so that tilting and misalignment are not likely to occur, thereby improving the stability of the fixing seat 4, and then ensuring the fixing of the terminal device in the direction (for example, the irradiation direction of the light source).

[0064] In the specific embodiment, please refer to Figure 3 and Figure 6 A pair of lugs 54 are also provided on both sides of the spring seat 52 , and the pair of lugs 54 are slidably connected to the slide grooves 55 of the elastic module 5 housing, so that the elastic module 5 as a whole can slide up and down in the slide grooves 55 through the lugs 54 .

The linkage rod mechanism is pivoted to the two side rods of the support rod, and the linkage rod mechanism is connected to the fixed seat. Therefore, when the user twists the fixed seat upward or downward, the linkage rod mechanism can follow the linkage, thereby converting the rotational movement of the fixed seat into a translational movement, thereby adjusting the position of the fixed seat up or down. In the process of turning downward, with the help of gravity potential energy, the user can easily rotate the fixed seat. In this process, the elastic module can convert the gravity potential energy of the fixed seat into elastic potential energy; in the process of moving upward, with the help of the elastic potential energy stored in the elastic module, the user can also easily rotate the fixed seat, and the elastic potential energy is converted into gravity potential energy.

The operation is convenient and simple, and the elastic potential energy of the elastic module can be used to reliably fix the fixed seat.
