[0037] like Figure 1-7 As shown, this embodiment provides a double-column lifting bed, including a bed body 10, a base 20, a telescopic column 30 and a driving device 40.
[0038] The bed body 10 may include a bed frame 11 and a bed board 12 laid on the bed frame 11. A fence 13 may be provided on the bed body 10, and other components may also be provided, such as a U-shaped clothes hanger 14 provided on the edge of the bed body 10 for hanging clothes. A telescopic column 30 is provided at each end of the bed body 10, each telescopic column 30 is fixedly connected to the middle of one end of the bed body 10, and each telescopic column 30 includes a fixed sleeve 31 and a movable sleeve 32, wherein the lower end of the fixed sleeve 31 is fixedly connected to the base 20, and the upper end of the movable sleeve 32 is fixedly connected to the bed body 10, and the fixed connection method may be bolt connection or welding. The lower end of the movable sleeve 32 is sleeved with the upper end of the fixed sleeve 31, and the movable sleeve 32 can move in the vertical direction to realize the telescopic column 30.
[0039] The driving device 40 is used to drive the telescopic column 30 to extend and retract. The driving device 40 includes a driving motor 41, a screw 42, a transmission tube 43 and a transmission mechanism 44. The driving motor 41 is installed on the bed 10. The driving motor 41 can be installed at the bottom of the bed 10 or at the end or side of the bed 10. The screw 42 is arranged in the movable sleeve 32 along the longitudinal direction, that is, it is arranged in the vertical direction. The screw 42 can rotate around its own axis. The screw 42 can be rotatably connected to the movable sleeve 32, or it can be directly or indirectly rotatably connected to the bed 10. The transmission tube 43 is arranged in the fixed sleeve 31, and is fixedly connected to the fixed sleeve 31 and / or the base 20, that is, it is fixedly connected to at least one of the fixed sleeve 31 and the base 20.

The screw 42 passes through the transmission tube 43 and is threadedly connected to the transmission tube 43. The transmission mechanism 44 is used to drive the drive motor 41 and the screw rod 42 to realize the rotation of the screw rod 42. When the screw rod 42 rotates, since the screw rod 42 is threadedly connected to the transmission tube 43, the movable sleeve 32 will extend upward or retract downward, thereby realizing the rise or fall of the bed body 10.
[0040] The double-column lifting bed provided in this embodiment uses two telescopic columns 30 to support the bed body 10, which reduces the number of supporting components and thus reduces the manufacturing cost.
[0041] In one embodiment, Figure 1 and 7As shown, the transmission mechanism 44 includes a housing 441, a first bevel gear 442 and a second bevel gear 443. The housing 441 is fixedly arranged on the bed 10, and the first bevel gear 442 and the second bevel gear 443 are both rotatably arranged in the housing 441, wherein the axis of the first bevel gear 442 is distributed in the vertical direction, and the first bevel gear 442 is coaxially connected with the screw rod 42, and can be directly fixedly connected with the screw rod 42, or can be connected with the screw rod 42 through a coupling. The axis of the second bevel gear 443 is distributed in the horizontal direction, and the second bevel gear 443 is meshed with the first bevel gear 442, and the second bevel gear 443 is transmission-connected with the output shaft of the drive motor 41, and can be directly fixedly coaxially connected with the output shaft of the drive motor 41, or can be connected with the output shaft of the drive motor 41 through a coupling.
[0042] In this embodiment, the transmission direction of the drive motor 41 is changed by the transmission mechanism 44, so that the drive motor 41 can be installed on the bed 10 in a horizontal manner. Since the length of the drive motor 41 in the axial direction is greater than the length in the radial direction, the horizontal installation of the drive motor 41 can reduce the space occupied under the bed 10.
[0043] In one embodiment, the transmission mechanism 44 further includes a third bevel gear rotatably disposed in the housing 441, the axis of the third bevel gear is distributed in the horizontal direction and is perpendicular to the axis of the second bevel gear 443, and the third bevel gear is meshed with the first bevel gear 442. The housing 441 is provided with a mounting hole for mounting the third bevel gear, the mounting hole is a through hole, and one end of the third bevel gear without bevel teeth has an operating hole extending from the end surface of the one end to the other end with bevel teeth to a certain depth, and the operating hole may be a regular polygonal hole.
[0044] In this embodiment, when the driving motor 41 cannot work, such as due to a power outage, a tool can be inserted into the operating hole to rotate the third bevel gear, thereby achieving manual lifting of the bed body 10 .
[0045] In one embodiment, Figure 1 and 2 As shown, the drive motor 41 is arranged in the middle of the bed body 10, the output shaft of the drive motor 41 has two power output ends, and the transmission mechanism 44 includes two coaxially arranged transmission rods 445, the two transmission rods 445 are respectively located at the two ends of the output shaft of the drive motor 41, one end of each transmission rod 445 is transmission-connected to a power output end of the output shaft of the drive motor 41, and the other end is transmission-connected to the second bevel gear 443. The two ends of the transmission rod 445 can be transmission-connected to the output shaft of the drive motor 41 and the second bevel gear 443 through a coupling, and the longitudinal section of the transmission rod 445 can be non-circular, such as a regular polygon, so as to facilitate the transmission of power after installation with the coupling.
[0046] In one embodiment, Figure 3 and 6 As shown, the driving motor 41 has a connecting plate 411, which is integrally connected to the driving motor 41, and the connecting plate 411 is detachably connected to the bed 10, and a shock-absorbing pad 413 is arranged between the connecting plate 411 and the bed 10. The shock-absorbing pad 413 can reduce the vibration of the driving motor 41 when it is working.
[0047] In one embodiment, Figure 3 and 6 As shown, the connecting plate 411 is provided with a plurality of first through holes 412 for installing the shock absorbing pads 413, and the shock absorbing pads 413 are snap-fitted in the first through holes 412.

Obviously, the diameter of the second through hole 414 is smaller than the diameter of the first through hole 412. The shock absorbing pads 413 can be a whole piece with a plurality of protruding structures that can be snap-fitted into the first through holes 412, or can be a plurality of separate parts. In this case, the shock absorbing pads 413 are arranged one-to-one with the first through holes 412. In this embodiment, the bolts for fixing the driving motor 41 pass directly through the second through holes 414 and then through the corresponding holes on the bed body 10, thereby facilitating the installation of the driving motor 41.
[0048] In one embodiment, Figure 6 As shown, one side of the first through hole 412 is opened, and a slot 415 cooperating with the first through hole 412 is provided on the shock-absorbing pad 413. Due to the existence of the above-mentioned slot 415, the shape of the shock-absorbing pad 413 is dumbbell-shaped. The shock-absorbing pad 413 is inserted into the first through hole 412 through one side of the opening of the first through hole 412, which facilitates the installation of the shock-absorbing pad 413.
[0049] In one embodiment, Figure 2 As shown, a support frame 50 is arranged between the two movable sleeves 32, and the support frame 50 is located below the bed body 10.

The bookshelf 60 is fixedly connected to the bed body 10, so the bookshelf 60 rises or falls with the bed body 10.
[0051] In one embodiment, Figure 1 and 2As shown, the movable sleeve 32 is sleeved outside the fixed sleeve 31 , so as to facilitate the installation of the support frame 50 at the lower end of the movable sleeve 32 .
[0052] In one embodiment, Figure 2 As shown, the base 20 includes a support leg 21 and a connecting rod 22, wherein two support legs 21 are arranged opposite to each other, the support leg 21 is fixedly connected to the bottom of the fixed sleeve 31, and the overall shape of the support leg 21 can be triangular, so that the stability is better. The connecting rod 22 is arranged in the transverse direction, that is, in the horizontal direction, and the connecting rod 22 connects the two support legs 21 together. The arrangement of the connecting rod 22 can enhance the stability of the base 20.
