Description

Technical Field

[0001] This utility model relates to the field of electric height-adjustable desks, specifically to a folding electric height-adjustable desk. Background Technology

[0002] As a key device for realizing the concept of "sitting and standing alternately," height-adjustable desks allow users to switch between sitting and standing postures while working at a desk, thus reducing the burden on the cervical and lumbar spine caused by prolonged sitting and promoting blood circulation. Furthermore, with advancements in motor control technology, electric height-adjustable desks have gradually become the mainstream product in the market. Electric height-adjustable desks use a single or dual motor to drive the extension and retraction of the telescopic columns (equivalent to desk legs), thereby raising and lowering the tabletop. The motors are generally installed at the top of the desk legs. Previously, for ease of transportation, the desk legs and tabletop were usually disassembled and stacked, requiring users to reassemble them upon receiving the product.

[0003] However, this method has certain drawbacks. Because the motor involves wiring and connection to the controller, users can easily make mistakes during installation, such as improper wiring or incorrect connections, leading to motor malfunction and inability to lift or lower. Therefore, this method is very cumbersome for non-professional users and may even damage the motor due to improper installation, significantly diminishing the user experience.

[0004] Therefore, it is necessary to improve upon existing technologies to provide an electric height-adjustable table that is easy to fold and install. Utility Model Content

Detailed Implementation

[0029] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0030] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] refer to Figure 1-6 This utility model provides a folding electric lifting table, including a tabletop 1, telescopic table legs 2 and a drive device 4. The telescopic table legs 2 are connected to the bottom of the tabletop 1, and the drive device 4 is connected to the telescopic table legs 2. The drive device 4 (e.g., a motor device) can drive the telescopic table legs 2 to extend and retract, and when the telescopic table legs 2 extend and retract, they can drive the tabletop 1 to rise and fall.

[0033] The telescopic table leg 2 has a connecting end and a grounding end (that is, the end that contacts the ground). The connecting end of the telescopic table leg 2 is connected to the tabletop 1, and the grounding end of the telescopic table leg 2 can be folded and retracted towards the tabletop 1 (e.g., ...). Figure 3 (As shown in the folded state), this facilitates folding the table legs without disassembling them, making storage and transportation convenient; alternatively, the ground end of the telescopic table leg 2 can be extended away from the tabletop 1 for support (e.g., Figure 2 (The image shows the unfolded state). Specifically, in this embodiment, when the electric height-adjustable desk needs to be folded for storage, simply fold the ground end of the telescopic leg 2 towards the tabletop 1. When the desk needs to be used, simply unfold the ground end of the telescopic leg 2 away from the tabletop 1 to achieve the supporting effect. The entire process requires no disassembly of the table legs; the two states can be switched simply by folding and unfolding. This makes it more convenient for users, eliminating the need for tedious disassembly and assembly steps, and requiring no professional assembly skills. Regardless of the state, the power cord of the drive device 4 does not need to be reinstalled; the cord remains connected. This allows the electric height-adjustable desk to immediately begin electric height adjustment after the legs are unfolded, further enhancing convenience and improving the user experience.

[0034] refer to Figure 2-4 In a preferred embodiment, the drive device 4 is disposed between the telescopic table leg 2 and the tabletop 1, and the telescopic table leg 2 is connected to the tabletop 1 through the drive device 4. In this embodiment, the telescopic table leg 2 is not directly connected to the tabletop 1; its connecting end is connected to the drive device 4, and is connected to the tabletop 1 through the drive device 4. In this case, the telescopic table leg 2 can rotate relative to the drive device 4 or relative to the tabletop 1, thereby realizing the folding or unfolding of the table leg; alternatively, the drive device 4 can rotate relative to the tabletop 1, while the connecting end of the telescopic table leg 2 is fixed to the drive device 4, so that when the drive device 4 rotates, it can drive the telescopic table leg 2 to fold or unfold.

[0035] refer to Figure 2 and 3In a further preferred embodiment, the driving device 4 includes a mounting base 40 and a driving source (e.g., a drive motor, not shown) fixed within the mounting base 40. The connecting end of the telescopic table leg 2 is connected to the mounting base 40 (specifically, it can be connected by bolt fixing). In this embodiment, the folding or unfolding of the telescopic table leg 2 is driven by the rotation of the mounting base 40. Specifically, the first end of the mounting base 40 is hinged to the tabletop 1 (see reference). Figure 2 ,by Figure 2 From a visual perspective, the right or left end of the mounting base 40 is hinged to the tabletop 1 as the first end, while the other end, as the second end, can rotate around its hinge axis with the tabletop 1. The mounting base 40 can rotate relative to the tabletop 1 between a folded position and an unfolded position. When the mounting base 40 rotates to the folded position, the grounding end of the telescopic table leg 2 folds and retracts towards the tabletop 1 (e.g., Figure 3 (As shown); When the mounting base 40 is rotated to the unfolded position, the grounding end of the telescopic table leg 2 unfolds to support the table in a direction away from the tabletop 1 (as shown). Figure 2 As shown), its rotation direction can be referenced. Figure 3 The direction indicated by the middle arrow. Furthermore, a main control board 10 is also provided at the bottom of the tabletop 1. The main control board 10 is electrically connected to the drive source, and the user can easily control the raising and lowering of the electric height-adjustable table through the main control board 10.

[0036] refer to Figure 2-5 In a preferred embodiment, to enable the telescopic table legs 2 to be easily folded and to provide stable support after unfolding, a locking device 3 is further included, which is disposed at both ends of the tabletop 1. The driving device 4 includes a mounting base 40, and the connecting end of the telescopic table legs 2 is connected to the tabletop 1 through the mounting base 40. The first end of the mounting base 40 is hinged to the tabletop 1. The mounting base 40 can drive the telescopic table legs 2 to fold and retract towards the tabletop 1, or drive the telescopic table legs 2 to unfold and support away from the tabletop 1. The second end of the mounting base 40 can be locked and fixed with the locking device 3. When the electric height-adjustable desk needs to be folded for storage, the locking device 3 unlocks from the mounting base 40. At this time, the second end of the mounting base 40 can rotate, thereby folding the telescopic table legs 2. When support is needed, the mounting base 40 drives the telescopic table legs 2 to unfold away from the tabletop 1. After unfolding to the desired position (meaning the upper surface of the mounting base 40 abuts against the lower surface of the tabletop 1), the second end of the mounting base 40 locks and secures itself to the locking device 3, thus ensuring the electric height-adjustable desk remains stably in the unfolded state. The entire process requires no disassembly / reassembly of the table legs; switching between the folded and unfolded states is achieved simply by changing the fixing state between the locking device 3 and the mounting base 40. Users can easily switch between these two states according to their needs, making it simple and convenient.

[0037] refer to Figure 1-4 In a preferred embodiment, the locking device 3 includes a fixing plate 30 and a locking bolt (not shown). One end of the fixing plate 30 is connected to the bottom of the tabletop 1, and the other end extends downward relative to the tabletop 1. A first locking hole 301 is provided on the fixing plate 30, and a second locking hole 401 that mates with the first locking hole 301 is provided on the mounting base 40. One end of the locking bolt can pass through the first locking hole 301 and be inserted into the second locking hole 401 to lock, so that the fixing plate 30 and the second end of the mounting base 40 are locked and fixed. During installation, it is only necessary to insert the locking bolt into the first locking hole 301110 and the second locking hole 40143 in sequence to lock and fix the fixing plate 30 and the mounting base 40. When it is necessary to rotate the mounting base 40 to achieve folding, it is only necessary to remove the locking bolt to separate the mounting base 40 from the fixing plate 30. At this time, the mounting base 40 can be rotated. The operation process is very simple. Of course, it is also possible that the fixing plate 30 and the mounting base 40 can be relatively fixed or separated by means of snap-fit ​​or fastening. Furthermore, a cover 31 is provided on the outer side of the fixing plate 30. The cover 31 is used to cover the first locking hole 301 and the locking bolt, thereby achieving dustproof and aesthetic effects. Similarly, the fixing method between the cover 31 and the fixing plate 30 is not limited to bolt fixing, snap-fit, fastening, or insertion, as long as it achieves relative fixation between the cover 31 and the fixing plate 30.

[0038] refer to Figure 2-4 In a preferred embodiment, a crossbeam 12 is also provided at the bottom of the tabletop 1, and the crossbeam 12 extends along the length of the tabletop 1; the driving device 4 includes a mounting base 40, which is disposed at both ends of the crossbeam 12. The first end of the mounting base 40 is hinged to the crossbeam 12, and the connecting end of the telescopic table leg 2 is connected to the mounting base 40; in this embodiment, two crossbeams 12 are provided, and the two crossbeams 12 are spaced apart, while the mounting base 40 is disposed between the two crossbeams 12 and at both ends of the crossbeams 12. This makes the stability of the mounting base 40 better during rotation. The first end of the mounting base 40 is provided with a first shaft hole 402, and the side of the crossbeam 12 facing the mounting base 40 is provided with a second shaft hole 120. The first shaft hole 402 and the second shaft hole 120 are connected by a hinge shaft 121 so that the mounting base 40 can rotate around the hinge shaft 121. Specifically, the first end of the mounting base 40 can also be understood as the end that is hinged to the crossbeam 12 (or the hinged end). First shaft holes 402 are opened on both sides of the mounting base 40, and second shaft holes 120 are opened on the side of the two crossbeams 12 facing the mounting base 40. The two shaft holes are connected by a hinge shaft 121, thereby forming a hinged state between the mounting base 40 and the crossbeam 12, so that the other end (second end) of the mounting base 40 can rotate around the hinge shaft between it and the crossbeam 12.

[0039] refer to Figure 4In a further preferred embodiment, a cable management plate 1113 is also provided at the bottom of the tabletop 11, and the cable management plate 1113 is fixed between the crossbeam 123 and the tabletop 11. Multiple cable routing grooves 110130 are provided on the cable management plate 1113, spaced apart along its length. Each cable routing groove 110130 extends along the width of the cable management plate 1113. There are multiple cable management plates 1113, which are spaced apart along the length of the tabletop 11. The cable management plates 1113 allow power cords of devices such as computers to pass through the cable routing grooves 110130 on the multiple cable management plates 1113, preventing the wires from becoming tangled and improving the overall neatness and aesthetics.

[0040] In a preferred embodiment, there are multiple telescopic table legs 2, which are spaced apart, for example... Figure 1 As shown, there are two telescopic table legs 2, which are arranged opposite each other at both ends of the tabletop 1 (there can also be three or four telescopic table legs 2). Each telescopic table leg 2 has a directional moving part 23 at its bottom, and the ground end is the directional moving part 23. The moving direction of at least one directional moving part 23 is along the length of the tabletop 1, so that the electric lifting table can achieve a certain directional moving effect to a certain extent.

[0041] In another preferred embodiment, there are multiple telescopic table legs 2, which are spaced apart, for example... Figure 1 As shown, there are two telescopic table legs 2, positioned opposite each other at both ends of the tabletop 1 (there can also be three or four telescopic table legs 2). Each telescopic table leg 2 has a directional moving part 23 at its bottom, with the ground end being the directional moving part 23. The movement direction of each directional moving part 23 is along the length of the tabletop 1. In other words, during use, the electric height-adjustable table can only move along the length of the tabletop 1, and cannot move along its width (i.e., it cannot move forward or backward relative to the user). This prevents the table from moving back and forth and distracting the user, helping to maintain focus.

[0042] refer to Figure 1-6 In a preferred embodiment, each telescopic table leg 2 includes a telescopic column 20, a front support leg 21, and a rear support leg 22. The telescopic column 20 is connected to the drive device 4, and the end of the telescopic column 20 away from the drive device 4 is connected to the front support leg 21 and the rear support leg 22. The bottom ends of both the front support leg 21 and the rear support leg 22 are provided with directional moving parts 23. Figure 4As shown, the front support leg 21 and the rear support leg 22 are respectively connected to both sides of the telescopic column 20, and each of the front support leg 21 and the rear support leg 22 is provided with a directional moving part 23 at the end away from the telescopic column 20. The directional moving part 23 serves as the grounding end of the telescopic table leg 2, and includes a swivel wheel 230 and a rotating shaft 231. The front end of the swivel wheel 230 (the end closest to the support leg) is connected to the rotating shaft 231. The swivel wheel 230 is rotatably connected to the front support leg 21 or the rear support leg 22 through the rotating shaft 231. The rotating shaft 231 can be an external thread bearing or other types of bearings. Taking an external thread bearing as an example, the rotating shaft 231 includes a screw and a bearing body. The bearing body is connected to the swivel wheel 230, and the screw is threadedly connected to the support leg, thereby realizing the installation and fixation between the swivel wheel 230 and the support leg, and also enabling the swivel wheel 230 to rotate relative to the support leg.

[0043] In this embodiment, the roller 230 is approximately truncated cone in axial cross-section, meaning that both ends of the roller 230 are relatively flat, while the outer wall of the roller 230 contacts the ground. This outer wall serves as the contact surface with the ground. The outer wall of the roller 230 extends obliquely from the front end to the rear end; or, it extends obliquely from the rear end to the front end. This oblique design of the outer wall of the roller 230 ensures that it can only roll along a fixed straight line (i.e., only along the length of the tabletop 1). Utilizing the self-guiding principle of the conical rolling surface, it effectively prevents accidental lateral sliding or arbitrary turning of the electric height-adjustable table during use or movement, thus improving overall stability.

[0044] refer to Figure 5 and 6 In a preferred embodiment, the telescopic table leg 2 includes a telescopic column 20, a front support leg 21, and a rear support leg 22. The telescopic column 20 is connected to the drive device 4, and the end of the telescopic column 20 away from the drive device 4 is connected to the front support leg 21 and the rear support leg 22. The front support leg 21 and the rear support leg 22 are asymmetrically arranged. During use, the front support leg 21 is closer to the user, and the rear support leg 22 is closer to the wall or other objects. This asymmetrical design of the front support leg 21 and the rear support leg 22 provides aesthetic appeal. In the folded state, the asymmetrical design of the two support legs creates a certain spatial misalignment, avoiding interference with components such as the mounting base 40, which is more conducive to storage. In the unfolded state, this asymmetrical design further enhances the overall stability of the height-adjustable table.

[0045] refer to Figure 5Furthermore, the front support leg 21 and the rear support leg 22 are respectively inclined in opposite directions relative to the telescopic column 20 (that is, the front support leg 2121 is inclined forward, and the rear support leg 2222 is inclined backward; here, "front" and "rear" refer to being closer to the user and being further away from the user); the extension line of the central axis of the front support leg 21 forms a first angle with the central axis of the telescopic column 20. Figure 5 In the middle α1), the extension line of the central axis of the rear support leg 22 forms a second included angle with the central axis of the telescopic column 20. Figure 5 In the middle α2), the first included angle is greater than the second included angle. The advantage of this design is that it allows the front support leg 2121 to form a longer forward support distance, making the electric lifting table more stable and less prone to tipping over when unfolded.

[0046] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
