Description

Technical Field

[0001] The present application relates to the technical field of electric lifting tables, and specifically relates to a compact drive lifting mechanism. Background Art

[0002] An electric lifting table is a table that can freely adjust the height of the tabletop through an electric drive system. It usually consists of a table frame, a motor, a drive actuator, and a tabletop. Users can easily raise or lower the tabletop to a comfortable position according to their needs and usage scenarios;

[0003] The drive actuator is relatively common in lifting, and can also be called a telescopic type, that is, when the motor starts, the circular motion is converted into a linear motion through a lead screw, and then the reciprocating telescopic motion of a certain component is driven. In such lifting devices, the installation space that basically needs to be reserved includes the volume of the motor, the length space of the reciprocating motion stroke of the lead screw plus the telescopic rod of the lifting component.

[0004] For example, the patent with the publication number CN206142767U specifically discloses a compact lifting device, which includes a lead screw driven by a motor, a housing covering the lead screw, and a nut fitted on the lead screw; a slot is opened in the abdomen of the housing along the axial direction of the lead screw, and the nut is sleeved on the lead screw and protrudes from the slot as an external installation connection seat. Thus, a simple design is achieved, the length is reduced by half, and the installation volume is greatly reduced.

[0005] When the above-mentioned patent lifting device is in use, the lead screw is driven to rotate forward by the motor, and the nut is sleeved on the lead screw. The reciprocating lifting motion is achieved. However, a slot is opened in the abdomen of the housing, so that the nut sleeve moves linearly in the slot. When applied to the lifting device of an electric lifting table, due to the setting of the slot, more dust or dirt will accumulate inside the housing after long-term use, thus affecting the use of the lifting device. Therefore, it is necessary to design a compact drive lifting mechanism to solve the above problems.

The lead screw sleeve 105 is located in the receiving groove, and the lead screw 104 is adapted to rotate with the output end of the drive motor 103 so that the lead screw sleeve 105 moves along the axial direction of the lead screw 104;

[0028] A fixing plate 106 is fixedly installed on the lead screw sleeve 105. The fixing plate 106 extends out of the receiving groove, and the fixing plate 106 is adapted to move synchronously with the movement of the lead screw sleeve 105. A number of holes (not marked in the figure) are provided on the fixing plate 106 for installation and fixation with external connectors;

[0029] Two sets of side baffles 108 are fixedly installed on the concave shell 101. The side baffles 108 are used for a certain degree of dust prevention for the receiving groove. At the same time, a sliding buckle groove (not marked in the figure) adapted to the size of the side baffles 108 is provided on the fixing plate 106;

[0030] Two sets of limiting rods 107 are fixedly installed between the two sets of side plates 102. The limiting rods 107 are located on both sides of the lead screw 104, and the lead screw sleeve 105 is movably sleeved on the two sets of limiting rods 107. The limiting rods 107 are used for linearly limiting the movement of the lead screw sleeve 105;

[0031] A motor cover 110 is fixedly installed on a set of side plates 102. The motor cover 110 is used for protecting the drive motor 103;

[0032] A fixed end 109 is fixedly installed on the other set of side plates 102. The fixed end 109 is used for the installation and fixation of the lifting component 1;

[0033] A dust-proof component 2 is connected between two groups of side plates 102 and a fixed plate 106. The dust-proof component 2 is composed of two groups of housing units. One group of housing units is installed on the side of the side plate 102, and the other group of housing units is installed on the side of the fixed plate 106. And the housing unit connected to the side of the side plate 102 is defined as the first housing unit, and the housing unit connected to the fixed plate 106 is defined as the second housing unit. And the first housing unit includes the housing unit fixedly installed on the side of the fixed plate 106. The housing unit includes a first arched cover 201 fixedly installed on the side of the side connection plate 102. Side plates 202 are fixedly installed on both sides of the first arched cover 201. Bolts 203 are connected to the side connection plates 202. The first arched cover 201 is fixed on the concave shell 101 through the bolts 203;

[0034] A first slide rail 204 is fixedly installed on the side of the first arched cover 201 facing the concave shell 101. And a second arched cover 206 is arranged at the lower end of the first arched cover 201. The size of the second arched cover 206 is slightly smaller than that of the first arched cover 201, so that the second arched cover 206 can be folded inside the first arched cover 201. At the same time, a first slider (not shown in the figure) adapted to the first slide rail 204 is fixedly installed on the second arched cover 206. The second arched cover 206 is slidably connected to the first slide rail 204 through the first slider;

[0035] A stop block 205 is fixedly installed at one end of the first slide rail 204. The stop block 205 is used to limit the movement of the first slider to prevent the first slider from slipping off the first slide rail 204. A second slide rail 207 is fixedly installed on the second arched cover 206;

[0036] A second housing unit is installed on the second slide rail 207. The second housing unit and the first housing unit have the same structure. And the size of the first arched cover 201 of the second housing unit is slightly smaller than that of the second arched cover 206 of the first housing unit. And the second arched cover 206 of the second housing unit is slightly smaller than the first arched cover 201 of the second housing unit;

[0037] So that as the fixed plate 106 moves and pushes the housing unit to move, the second arched cover 206 of the second housing unit can be folded inside the first arched cover 201 of the second housing unit. At the same time, the first arched cover 201 of the second housing unit is folded inside the second arched cover 206 of the first housing unit. And the second arched cover 206 of the first housing unit can be folded inside the first arched cover 201 of the first housing unit to adapt to the movement of the fixed plate 106 and can prevent dust from entering the receiving groove of the concave shell 101;

[0038] Working principle:

[0039] During operation, when driving the lifting assembly 1 to work, the driving motor 103 is started to drive the lead screw 104 to rotate forward. The fixed plate 106 is sleeved on the lead screw 104 through the lead screw sleeve 105, and is restricted by the limiting rod 107 and cannot rotate, but can only move linearly along the direction of the lead screw 104. At the same time, the second arched cover 206 of the second housing unit slides out of the first arched cover 201 of the second housing unit. At the same time, the first arched cover 201 of the second housing unit slides out of the second arched cover 206 of the first housing unit, and the second arched cover 206 of the first housing unit slides out of the first arched cover 201 of the first housing unit, so as to be able to adapt to the movement of the fixed plate 106 and can dust-proof the receiving groove of the concave shell 101;

[0040] Due to the reverse rotation of the lead screw 104, the fixed plate 106 moves back, realizing a reciprocating lifting motion. The length space of the lead screw 104 of the present utility model can be used as the space for the reciprocating stroke, and the installation volume is greatly reduced.

[0041] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
