Large-stroke lifting table and bed combination

Abstract

The invention discloses a lifting table and bed combination with a large stroke. The lifting table and bed combination comprises a supporting structure, a bed body, a table top and a lifting assembly. The supporting structure comprises four supporting column rods which are vertically arranged; the bed body is fixed to the lower portion of the supporting column rod. The table top is fixed to the middle of the supporting column rod through the lifting assembly. The lifting assembly comprises a lead screw, a driving motor, a gear box and a lifting pause device which are arranged in the supporting column rod. The lifting pause device is connected with the four lead screws and the table top. When the lifting assembly moves, the driving motor drives the lead screw to rotate through the gearbox, and therefore the lifting pause device is driven to move up and down. When the lifting assembly stops moving, the lifting pause device and the supporting column rod are locked. According to the combined structure of the bed body and the lifting table top of the lifting table-bed combined device, large-stroke lifting of the table top from the ground to the high altitude can be achieved through the lead screw, the motor and the lifting pause device, lifting of the table top at any height can be customized for the lifting table-bed combined device, and meanwhile space is saved.

Detailed implementation manner

[0032] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] As Figure 1 shown, a lifting table - bed combination with a large stroke includes:

[0034] a support structure, a bed body, a tabletop 8 and a lifting assembly;

[0035] The support structure includes four vertically - arranged support column rods;

[0036] The bed body is fixed to the lower part of the support column rods; the tabletop 8 is fixed to the middle part of the support column rods through the lifting assembly;

[0037] The lifting assembly includes lead screws 3 arranged in four support column rods, a driving motor, a gearbox and a lifting pause device 9;

[0038] Four lifting pause devices are respectively connected to the four lead screws and the tabletop, and the tabletop is fixed on the four lifting pause devices;

[0039] The gearbox is arranged at the top of the lead screw, and the gearbox is a bevel gear steering box;

[0040] When the lifting assembly moves, the driving motor drives the lead screw to rotate through the gearbox, thereby driving the lifting pause device to move up and down;

[0041] When the lifting assembly stops moving, the lifting pause device stops moving and locks with the support column rod.

[0042] When there is no need for lifting, when the lifting pause device stops moving, the fixing part in the lifting pause device can be controlled to lock with the support column rod, and at the same time, the lifting pause device is separated from the lead screw.

[0043] The driving motor is arranged at the top of the lead screw, including two driving motors, which are respectively arranged on the head side and the tail side of the top of the support structure, that is, the head side and the tail side of the corresponding bed body.

[0044] The lifting pause device is provided with an infrared sensor for keeping the horizontal heights of the four lifting pause devices consistent.

[0045] When the heights are inconsistent, the drive motor will adjust the speed of one of the motors to correct it.

[0046] For example Figure 2 and Figure 3 , the bed body includes a bed frame and a foldable bed body; the bed frame is fixed to the lower part of the support column rod, and a backrest angle adjuster 7 is provided on both sides of the foldable bed body;

[0047] When rest is needed, the tabletop 8 rises to a suitable position from the ground, and the user can rest on the folding bed 1. Flip one end of the folding bed 1 and adjust it to a suitable angle through the backrest angle adjuster to use it as a backrest; when entertaining, flip the folding bed against the inner edge of the bed and adjust it to a suitable angle through another backrest angle adjuster to transform the folding bed into a sofa. It is convenient for various uses in different scenarios.

[0048] For example Figure 4 , the bottom of the support column rod is provided with retractable rollers, and the retractable rollers include a telescopic mechanism and rollers;

[0049] When the bed table needs to be moved, insert the hex wrench into the adjusting wheel 502, press down the hex wrench, and the roller 503 is pushed out of the support column 2 by the rotated adjusting wheel 502. Then the locking device and the isolation plate fix the adjusting wheel, and the bed table can be moved arbitrarily; when the bed table is moved to a suitable position, lift the hex wrench, the adjusting wheel 503 returns to its original position, and the roller 503 retracts into the support column 2, and the bed table can be placed stably.

[0050] The upper part of the support structure is provided with a second bed body 10, and the second bed body is above the tabletop.

[0051] For example Figure 5 , multiple tabletops can be provided in the middle of the support column rod.

[0052] In this embodiment, the tabletop 8 is preset to be able to be lifted to 5 gears, including: children's sitting gear (300mm), children's standing gear (500mm), adult sitting gear 1 (750mm), adult sitting gear 2 (1000mm), adult standing gear (1250mm). A gear is set at every certain distance above the fifth gear to facilitate the use requirements of users of different heights in different scenarios.

[0053] Adult sitting gear 1 is used when both are working at the same time, and adult sitting gear 2 is used when one of them gets out of bed to sleep and the other is studying.

[0054] The above gear positions and the transmission device as a whole can be controlled by a circuit. An infrared sensor is provided on the side of the lifting pause device. An electric control panel can be set on the side of the lifting table. Each gear position switch is displayed on the control panel. When the gear position switch is toggled, the drive motor above the combined lifting bed table is controlled to start working and drives the lead screw to rotate under the action of the gearbox. The lifting pause device drives the table surface to move to the specified gear position. When the side of the lifting pause device touches the micro switch upon reaching the specified gear position, i.e., the table surface reaches the corresponding position, the current is interrupted and the motor stops rotating. At the same time, the lifting pause device is activated and the bed frame is locked.

[0055] The second bed body can also be provided with the same bed body lifting pause device. The second bed body is fixed to the support column rod through the bed body lifting pause device, and the bed body lifting pause device is connected to the lead screw. The lifting of the bed and the table surface can share one motor. When the lifting pause device corresponding to the table surface disengages from the lead screw and is locked with the support column, the bed body can be lifted onto the bed independently using the bed body lifting pause device. It can also be set to lift and lower simultaneously.

[0056] The multiple table surfaces provided can also be lifted and lowered in the same way.

[0057] It should be understood that those of ordinary skill in the art can make improvements or transformations based on the above description, and all such improvements and transformations shall fall within the protection scope of the appended claims of the present invention.
