Description

Electric height adjustable table

Technical Field

The present application relates to the technical field of furniture equipment, and in particular to an electric lifting table.

Background technique

An electric lift table is a table that can be electrically lifted and adjusted in height. It can adjust the appropriate height according to the user's height to meet the user's needs. The electric lift table has a wide range of applications and diverse functions. It can be used not only for office desks and study tables, but also for e-sports tables, fitness tables, etc. In order to meet the needs of users, the electric lift table of the related technology sets the table top into two pieces, that is, a first table top and a second table top are set. The first table top and the second table top are distributed in sequence along the width direction of the electric lift table. The first table top is also called the front table top, and the second table top is also called the back table top. The lifting of the front and rear table tops is done by a set of lifting systems, such as the structure of the electric lifting table disclosed in the patent application with publication number CN219165884U and the name of the electric lifting table previously applied by the applicant of this case. The structure includes a first table top and a second table top. The first table top is fixed to the top of the first movable column of a pair of first electric lifting column assemblies at both ends. A horizontal beam is fixed on one side of the two first movable columns. A second fixed column of the second electric lifting column assembly is fixed on each horizontal beam. The tops of the two second movable columns that slide with their respective second fixed columns are fixed to the two ends of the second table top. When the first table top is lifted or lowered, it can drive the second table top to rise or fall synchronously, and the second table top can be lifted or lowered independently to adjust the height.

The electric lifting table of the related technology has the following defects during actual use: first, the position where the transverse cantilever beam is fixed on the first movable column has errors due to welding and assembly errors, resulting in errors in the height of the two transverse cantilever beams relative to the base, as well as assembly errors of the two second movable columns themselves, or assembly errors of the transmission rod components between the two second movable columns, which can all lead to different left and right heights of the two second movable columns, and the rear table plate is tilted left and right and is not flush with the front table plate; secondly, the lifting column of the related technology is generally equipped with a self-locking torsion spring to prevent the lifting column from passively shrinking due to overweight, such as the self-locking torsion spring on the lifting column in the patent application with publication number CN218543094U or CN218185898U. During the descent of the lifting column, due to the friction between the self-locking torsion spring and the torsion spring seat, the self-locking torsion spring always applies a reverse rotational force to the lead screw of the lifting column. When the lowering column descends to the lowest position, it has an upward rebound height, that is, the lifting column will rebound a certain distance or height upward after it is contracted to the lowest position of the structure, and the position of the lifting column at the rebound height is the lowest descending height of the lifting column set by the internal control program of the electric lifting table; wherein, the lowest position of the lifting column structure is also the lowest position or lowest height of the lifting column after the assembly is completed; therefore, there is a certain height difference between the lowest position of the lifting column structure and the lowest position of the actual lifting column descent, that is, the lowest position of the lifting column descent is slightly higher than the lowest position of the lifting column structure; in this way, when assembling the electric lifting table, people are accustomed to keeping the tops of the front and rear table boards flush to complete the assembly first, then in actual use, due to the rebound height of the lifting column, when the lifting column drives the rear table board to descend to the lowest position, the rear table board is often higher than the front table board, thereby causing the tops of the front and rear table boards to be uneven.

The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

1 to 8 , the present embodiment discloses an electric lift table, which includes a table top assembly, a base 4, two transverse beams 5, two first electric lift columns 2 and two second electric lift columns 3, wherein the table top assembly includes a first table top 1 and a second table top 100, which are sequentially distributed along the width direction of the electric lift table, the first table top 1 is also called the front table top, and the second table top 100 is also called the rear table top; the upper ends of the two first electric lift columns 2 are connected to the first table top 1, and the lower ends of the two first electric lift columns 2 are connected to the base 4. In the present embodiment, there are two bases 4, which are respectively connected to the lower ends of the two first electric lift columns 2. The first electric lifting column 2 includes a first movable column 200 and a first fixed column (not shown in the figure), the first movable column 200 and the first fixed column are also called an outer tube and an inner tube, the first movable column 200 is slidably sleeved on the first fixed column, the lower end of the first fixed column is connected to the base 4, and the upper end of the first movable column 200 is connected to the first table board 1; a linear drive mechanism is arranged in the first fixed column, and the action of the linear drive mechanism can drive the first movable column 200 to axially move relative to the first fixed column or the base 4 to expand or contract. A first transmission rod is arranged between the two first electric lifting columns 2, and the two ends of the first transmission rod are respectively connected to the linear drive mechanisms in the two first electric lifting columns 2. The rotation of the first transmission rod can simultaneously drive the linear drive mechanisms in the two first electric lifting columns 2 to move, thereby causing the two first electric lifting columns 2 to rise or fall. It is not difficult to understand that a first drive motor is connected between the two first electric lifting columns 2, and the first drive motor is connected to the first transmission rod for driving the first transmission rod to rotate.

In this embodiment, the second table top 100 is connected to the second movable columns 300 of the two second electric lifting columns 3, and the lower ends of the two second electric lifting columns 3 are respectively connected to the two transverse beams 5; specifically, the second electric lifting column 3 includes a second movable column 300 and a second fixed column 301, the lower end of the second fixed column 301 is connected to the transverse beam 5, the second movable column 300 is axially sleeved in the second fixed column 301 and can move axially relative to the second fixed column 301; the second fixed column 301 is equivalent to an outer tube, the second movable column 300 is equivalent to an inner tube, and the upper end of the second movable column 300 is connected to the second table top 100; a linear drive mechanism is provided in the second movable column 300, and the action of the linear drive mechanism can drive the second movable column 300 to axially move relative to the second fixed column 301 or the transverse beam 5 to expand or contract. A second transmission rod is provided between the two second electric lifting columns 3, and both ends of the second transmission rod are respectively connected to the linear drive mechanisms in the two second electric lifting columns 3. The rotation of the second transmission rod can simultaneously drive the linear drive mechanisms in the two second electric lifting columns 3 to move, thereby raising or lowering the two second electric lifting columns 3. It is not difficult to understand that a second drive motor is connected between the two second electric lifting columns 3, and the second drive motor is connected to the second transmission rod for driving the second transmission rod to rotate.

In this embodiment, the linear drive mechanism in the first electric lifting column 2 and the second electric lifting column 3 is also called a screw-nut pair, or a linear transmission mechanism, etc., which drives the screw to rotate through the motor, so that the transmission nut threaded on the screw drives the movable column in the lifting column to move axially relative to the fixed column, thereby adjusting the height of the lifting column. It is a component of the prior art and is not described in detail in this embodiment; it is worth mentioning that, in this embodiment, at least the screw of the linear drive mechanism in the second electric lifting column 3 is connected with a self-locking torsion spring, which is used to hold the screw tightly when the lifting column is passively contracted due to overweight, thereby preventing the screw from rotating and stopping the passive contraction of the lifting column.

As shown in Figures 1, 2 and 3, in this embodiment, the two first movable columns 200 are respectively connected with mounting seats 201. Specifically, the mounting seats 201 are arranged in a U shape, and the mounting seats 201 are welded and fixed to the outer wall of the first movable column 200, and a gap is provided between the end of the mounting seat 201 facing the transverse cantilever beam 5 and the outer wall of the first movable column 200; the two transverse cantilever beams 5 respectively correspond to the two mounting seats 201 and are arranged on the side of the two first electric lifting columns 2 close to the second table board 100, and the two transverse cantilever beams 5 both have a connecting portion detachably connected to the mounting seat 201, and the connecting portion has at least an adjustment gap along the axial direction of the first movable column 200 relative to the mounting seat 201, so as to make the height of the transverse cantilever beam 5 on the first movable column 200 adjustable. When assembling the electric lifting table, the height of the transverse beam 5 can be adjusted relative to the first movable column 200, that is, after the connecting part of the transverse beam 5 is adjusted in the vertical direction relative to the mounting seat 201, the two are connected together to ensure that the heights of the two second electric lifting columns 3 are the same, avoiding the second table top 100 from tilting at different heights on the left and right; therefore, the electric lifting table can eliminate or reduce assembly errors and keep the left and right heights of the second table top 100 consistent.

In some embodiments, as shown in FIG. 4 to FIG. 7 , a connecting plate 503 is connected to one end of the transverse cantilever beam 5 close to the mounting seat 201, and the connecting plate 503 is provided with at least one mounting hole 504 extending in the vertical direction, and each mounting hole 504 is fitted with a connecting screw 505 in a clearance, and the mounting seat 201 is provided with a connecting hole 202 correspondingly connected to the connecting screw 505; the connecting plate 503, the mounting hole 504 and the connecting screw 505 form the connecting portion. In this embodiment, the connecting hole 202 on the mounting seat 201 is a threaded hole, and when the transverse cantilever beam 5 is installed, the free end of the connecting screw 505 in the mounting hole 504 is connected to the connecting hole 202. Since the mounting hole 504 extends in the vertical direction on the connecting plate 503, the height of the transverse cantilever beam 5 can be adjusted. After the height of the transverse cantilever beam 5 is adjusted, the connecting screw 505 can be locked to fix the height of the transverse cantilever beam 5.

As mentioned above, a second transmission rod is connected between the two second electric lifting columns 3. Therefore, when the second transmission rod is assembled, both ends of the second transmission rod need to be connected to the linear drive mechanisms in the two second electric lifting columns 3. Therefore, when the two ends of the second transmission rod are respectively connected to the linear drive mechanisms in the two second electric lifting columns for transmission and installation, due to the assembly error of the linear drive mechanism or the different transmission angles of the transmission rod assembly, the heights of the two second electric lifting columns 3 in the initial state (folded or retracted to the shortest length) are often different; or, when the mounting seat 201 is welded to the first movable column 200, the deviation of the welding position, etc., can cause the left and right heights of the two second electric lifting columns 3 to be different; in this way, the height of the transverse cantilever beam 5 on the mounting seat 201 can be adjusted according to the actual installation situation. When adjusting, the height of the transverse cantilever beam 5 can be adjusted by loosening the connecting screw 505. The height adjustment is simple and convenient.

In other embodiments, a mounting hole 504 extending in the vertical height direction may also be provided on the mounting seat 201, a connection screw 505 is provided in the gap of the mounting hole 504, and a connection hole 202 or a threaded hole is provided on the connecting plate 503 of the transverse cantilever beam 5, that is, the connection hole 202 and the mounting hole 504 in the above embodiment are interchanged on the connecting plate 503 and the mounting seat 201. Similarly, in other embodiments, the number and shape of the mounting holes 504 may be set according to actual needs.

In some embodiments, as shown in Fig. 4, Fig. 5 and Fig. 7, the top of the transverse cantilever beam 5 is threadedly connected to a vertically arranged limit screw 503, and the free end of the limit screw 503 abuts against one of the connecting screws 505, so as to locate the connecting screw 505 in the mounting hole 504. Specifically in this embodiment, the interior of the transverse cantilever beam 5 is hollow, and the connecting plate 503 is vertically connected in the transverse cantilever beam 5, and a space 506 is provided between the connecting plate 503 and the end surface of one end of the transverse cantilever beam 5 close to the mounting seat 201, and the free end of the limit screw 503 is passed through the space 506 from top to bottom and abuts against the connecting screw 505 in the space 506. When the free end of the connecting screw 505 is connected to the connecting hole 202 on the mounting base 201, rotate the limiting screw 503 so that the free end of the limiting screw 503 abuts against the top of one of the connecting screws 505. This can limit the connecting screw 505 from sliding in the mounting hole 504, thereby preventing the transverse cantilever beam 5 from accidentally sliding downward or loosening due to the excessive load of the second table top 100, thereby greatly improving the supporting performance and load-bearing capacity of the transverse cantilever beam 5.

In order to make it convenient for users to tighten or loosen the connecting screws 505 and to facilitate the height adjustment of the transverse cantilever beam 5, a first avoidance hole 500 corresponding to the connecting screw 505 is opened on each transverse cantilever beam 5, and in order to keep the surface of the transverse cantilever beam 5 smooth, a detachable cover plate can be connected to the first avoidance hole 500.

In some embodiments, in order to make the distance between the second table board 100 and the first table board 1 adjustable and avoid unequal spacing between the second table board 100 and the first table board 1, as shown in Figures 5 and 6, a plurality of adjustment holes 507 extending along the length direction of the transverse beam 5 are provided on the top of the transverse beam 5, and the bottom of the second electric lifting column 3 is connected to the adjustment hole 507 through the fastener 302, and the second electric lifting column 3 can adjust the position along the length direction of the adjustment hole 507 to adjust the gap between the second table board 100 and the first table board 1. Similarly, in order to facilitate users to loosen or tighten the fastener 302, a second avoidance hole 501 corresponding to the fastener 302 is opened on each transverse beam 5.

In some embodiments, as shown in FIG. 2 and FIG. 3 , a vertical baffle 101 extending downward is fixed on one side of the second table board 100 close to the first table board 1, and a gap for preventing friction is left between the vertical baffle 101 and the first table board 1; the height of the vertical baffle 101 is configured such that when the second table board 100 is at a maximum height position higher than the first table board 1, the bottom end of the vertical baffle 101 is still located below the top plane of the first table board 1 or flush with the top plane of the first table board 1. When the second table board 100 is higher than the height of the first table board 1, the vertical baffle 101 can prevent items on the first table board 1 from falling from the back side of the first table board 1, and can also prevent hands from being accidentally extended under the second table board 100 and being pinched when the second table board 100 descends relative to the first table board 1. Similarly, when the second table top 100 is raised to the highest position relative to the first table top 1, it can still ensure that the items on the first table top 1 do not fall from the back side of the first table top 1, and it can also prevent the second table top 100 from initially descending from the highest position. The hands will not be pinched by the vertical baffle 101 and the second table top 100, and the safety is high.

In this embodiment, as mentioned above, the lifting column will rebound a certain distance or height after it is retracted to the lowest position of the structure. Therefore, there is a certain height difference between the lowest position of the lifting column structure and the lowest position of the actual lifting column descent, that is, the lowest position of the lifting column descent is slightly higher than the lowest position of the lifting column structure. In order to eliminate the rebound height of the lifting column, the second table plate 100 is kept flush with the first table plate 1 when it is dropped to the lowest position. Therefore, after the electric lifting table is assembled, the height of the top plane of the second table plate 100 is lower than the height of the top plane of the first table plate 1, and the height difference between the first table plate 1 and the second table plate 100 is equal to the rebound height of the second electric lifting column 3.

Specifically, in the case of an electric lifting table, the electric lifting table can be inverted so that the first table top 1 is facing downward and in contact with the ground, and a plurality of support pads 6 are placed around the second table top 100, each support pad 6 includes two vertical plates 600 that are perpendicular to each other and in a cross shape and a horizontal plate 601 arranged between the two vertical plates 600, and the horizontal plate 601 and the two vertical plates 600 are an integrally formed structure; the bottom of the horizontal plate 601 of the support pad 6 has a first plane 602 that is in contact with the top plane of the second table top 100, and the top of the horizontal plate 601 has a second plane 603, and the distance between the first plane 602 and the second plane 603 is equal to the rebound height of the second electric lifting column 3; therefore, the first plane 602 of the support pad 6 is always kept in contact with the top plane of the second table top 100, and the second plane 603 is flush with the top plane of the first table top 1 or in contact with the ground. After the electric lifting table is assembled, all support pads 6 are removed. After the electric lifting table is assembled, the two first electric lifting columns 2 and the second electric lifting columns 3 are both in a reset state or the lowest reset state of the structure. At this time, the height of the second table board 100 is lower than the height of the first table board 1, and the height difference between the second table board 100 and the first table board 1 is equal to the rebound height of the second electric lifting columns 3. In this way, when in use, for example, when the second table board 100 starts to rise to a certain height and then returns to the lowest position, due to the existence of the rebound height of the second electric lifting columns 3, the second table board 100 can be kept flush with the first table board 1; in other words, when the electric lifting table is assembled, the rebound height of the second electric lifting columns 3 is reserved in advance. When the two first electric lifting columns 2 and the two second electric lifting columns 3 are both in a reset state or the lowest reset state of the structure, the height of the second table board 100 is lower than the height of the first table board 1, and the height difference between the two is exactly equal to the rebound height of the second electric lifting columns 3. In this way, in actual use, especially when the second table board 100 rises and then falls alone, it can be kept flush with the first table board 1. Therefore, the electric lifting table can eliminate or reduce the defect that the second table top 100 and the first table top 1 cannot be kept flush due to the rebound height of the second electric lifting column 3 .

Moreover, the setting of the supporting pad 6 can keep the side walls of the second table board 100 and the first table board 1 flush with each other, that is, the side walls of the second table board 100 and the first table board 1 are simultaneously fitted with the side walls of the vertical board 600; it can also keep the gap between the second table board 100 and the first table board 1 equal on the left and right, that is, insert another vertical board 600 into the gap between the second table board 100 and the first table board 1, and the two sides of the vertical board 600 are respectively fitted with the corresponding side walls of the second table board 100 and the first table board 1.
