[0001] This utility model relates to the field of height-adjustable desk technology, specifically to a high-strength height-adjustable desk assembly with a single motor, double legs, and an L-shaped tabletop. Background Technology

[0002] Automatic height-adjustable desks use a motor to raise and lower the desktop, allowing users to alternate between sitting and standing, thus avoiding the health risks of prolonged sitting. The main types of desks on the market are L-shaped and horizontal. The L-shaped desk design doubles the desktop space, better meeting various needs for working, studying, or creating.

[0003] For example, Chinese patent document CN215501727U discloses an L-shaped height-adjustable desk, including an L-shaped desktop, a corresponding L-shaped crossbeam support mounted on the back of the L-shaped desktop, lifting columns mounted at both ends and corners of the L-shaped crossbeam support, a lead screw assembly and a coupling connected to the lead screw assembly installed in each lifting column, including a crank handle, a housing provided at the top of each lifting column, a converter connected to the coupling provided in the housing, the converters in the housings of adjacent lifting columns are connected by a transmission rod, and the crank handle is connected to the converter in the housing of one of the lifting columns located at the end of the L-shaped crossbeam support.

[0004] In the above technical solution, due to the design of the L-shaped desktop, its cross-section is triangular. Therefore, in order to ensure that the overall center of gravity does not deviate from the support area of ​​the column, it is generally necessary to install columns at each end of the desktop. Thus, three columns need to be installed, which results in a large overall weight and production cost of the height-adjustable desk. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-strength lifting table component with a single motor and double legs L-shaped tabletop. By optimizing the installation relationship between the column and the transmission mechanism, the overall stability of the lifting table can be ensured while reducing the number of columns installed, so as to achieve the overall lightweighting of the lifting table and reduce production costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength lifting table assembly with a single motor and two legs, comprising an L-shaped tabletop, two columns below the L-shaped tabletop, the columns being respectively positioned at the center of the long side and the center of the short side of the L-shaped tabletop, so that the supporting area formed by the columns covers the center of gravity of the L-shaped tabletop, a transmission mechanism is provided between the two columns, the transmission mechanism being inclined at an angle to the columns, so that the setting direction of the transmission mechanism coincides with the connecting line between the center of the long side and the center of the short side of the L-shaped tabletop.

[0007] The present invention is further configured such that: the column includes a fixed part and a lifting part, and the lifting part is fitted around the outer periphery of the column.

[0008] The present invention is further configured such that: a drive motor is provided below the L-shaped desktop, and the drive motor drives the lifting parts on both sides to slide along the fixed part simultaneously through a transmission mechanism, so as to realize the lifting of the L-shaped desktop.

[0009] The present invention is further configured such that: a connecting plate is fixed to the top of the fixing part, the connecting plate is provided with a connecting part perpendicular to the end face of the connecting plate, the connecting plate is used to fix the L-shaped desktop, and the connecting part is used to fix the drive motor.

[0010] The present invention is further configured such that: the transmission mechanism includes a gearbox and a transmission rod; the gearbox is disposed inside the lifting part and fixed to the connecting plate; the lifting part is provided with a connection port communicating with the interior of the lifting part; one side of the output end of the drive motor extends toward the connection port and is connected to the input end of the gearbox; one end of the transmission rod is connected to the input end of the drive motor and the other end is connected to the input end of the gearbox.

[0011] The present invention is further configured such that: the output end of the gearbox is connected to a lead screw, a drive block is fixed to the top inner wall of the fixing part, the drive block is fitted around the outer periphery of the lead screw, and can form a threaded engagement with the lead screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Because columns are installed at the center of the long and short sides of the L-shaped tabletop, only two columns are needed. This ensures that the supporting area between the two columns covers the center of gravity of the L-shaped tabletop, reducing the number of columns required while maintaining overall stability. This effectively solves the technical problem of existing L-shaped tabletop lifting desks requiring three columns for stable support. Furthermore, it enables lightweighting and reduces production costs. Additionally, since the line connecting the center of the long and short sides of the L-shaped tabletop is not horizontal, aligning the transmission mechanism with this line ensures proper power transmission, facilitating the lifting of the L-shaped tabletop.

[0019] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figures 1 to 5 As shown, this utility model discloses a high-strength lifting table assembly with a single motor and double legs L-shaped tabletop, including an L-shaped tabletop 1. Two columns 2 are provided below the L-shaped tabletop 1. The columns 2 are respectively set at the center of the long side and the center of the short side of the L-shaped tabletop 1, so that the supporting area formed by the columns 2 covers the center of gravity of the L-shaped tabletop 1. A transmission mechanism is provided between the two columns 2. There is an inclination angle between the transmission mechanism and the columns 2, so that the setting direction of the transmission mechanism coincides with the connecting line between the center of the long side and the center of the short side of the L-shaped tabletop 1.

[0022] Since columns 2 are installed at the center of the long side and the center of the short side of the L-shaped desktop 1, only two columns 2 are needed. At the same time, the supporting area formed between the two columns 2 can cover the center of gravity of the L-shaped desktop 1. This reduces the number of columns 2 required while ensuring the overall stability of the lifting table. This results in a lighter overall weight and reduced production costs. In addition, the line connecting the center of the long side and the center of the short side of the L-shaped desktop 1 is not horizontal. Therefore, by aligning the direction of the transmission mechanism with the line connecting the center of the long side and the center of the short side of the L-shaped desktop 1, the power can be transmitted normally to drive the L-shaped desktop 1 to rise and fall.

[0023] In this embodiment, the column 2 includes a fixed part 21 and a lifting part 22. The lifting part 22 is fitted around the outer periphery of the column 2. Thus, by sliding the lifting part 22 along the fixed part 21, the L-shaped tabletop 1 can be raised and lowered.

[0024] The L-shaped desktop 1 is provided with a drive motor 3 below it. The drive motor 3 drives the lifting parts 22 on both sides to slide along the fixed part 21 at the same time through the transmission mechanism, so as to realize the lifting of the L-shaped desktop 1. In this way, a single drive motor 3 can drive the lifting parts 22 on both sides to slide along their respective fixed parts 21, so as to drive the L-shaped desktop 1 to lift.

[0025] In this embodiment, the installation structure of the drive motor 3 is as follows: a connecting plate 4 is fixed on the top of the fixing part 21, and a connecting part 41 perpendicular to the end face of the connecting plate 4 is provided on the connecting plate 4. The connecting plate 4 is used to fix the L-shaped desktop 1, and the connecting part 41 is used to fix the drive motor 3, so that the installation of the drive motor 3 can be realized.

[0026] In this embodiment, the specific structure of the transmission mechanism includes a gearbox 51 and a transmission rod 52. The gearbox 51 is disposed inside the lifting part 22 and fixed to the connecting plate 4. The lifting part 22 is provided with a connection port 221 that communicates with the interior of the lifting part 22. One side of the output end of the drive motor 3 extends toward the connection port 221 and is connected to the input end of the gearbox 51. One end of the transmission rod 52 is connected to the input end of the drive motor 3, and the other end is connected to the input end of the gearbox 51.

[0027] Furthermore, a lead screw 6 is connected to the output end of the gearbox 51, and a drive block 7 is fixed to the top inner wall of the fixed part 21. The drive block 7 is fitted around the outer periphery of the lead screw 6 and can form a threaded engagement with the lead screw 6. Thus, by driving the lead screw 6 to rotate through the drive motor 3, the lead screw 6 can be raised and lowered under the action of the threaded engagement with the drive block 7, thereby driving the lifting part 22 connected to the gearbox 51 to slide along the fixed part 21. In addition, the inner wall of the sliding part abuts against the outer wall of the fixed part 21, so that the sliding of the lifting part 22 can guide the sliding of the lifting part 22 during the sliding process along the fixed part 21. Furthermore, the drive motor 3 and the gearbox 51 used in this solution are a right-angle drive motor 3 and a right-angle gearbox 51, respectively, each of which adopts a bevel gear pair to realize the conversion between lateral rotation and longitudinal rotation.

[0028] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
