fig. 1 and 2 are perspective views (fig. 2 partially cut away and partially exploded) of an electric infant bed according to an embodiment of the present invention at different viewing angles;
fig. 3 is a perspective view (enlarged compared to fig. 1 and 2) illustrating power transmission between the motor and the left and right driving levers according to the present invention.
Detailed Description
Examples, see fig. 1-3: the electric baby crib comprises a left leg 71, a right leg 72 and a crib body 20.
Further speaking:
this electronic crib still includes: a left U-shaped slide rail 11, a right U-shaped slide rail 12, a left bottom branch pipe 31, a right bottom branch pipe 32, a driving shaft 40 and a motor 50.
The left U-shaped slide rail 11 and the right U-shaped slide rail 12 are both vertically arranged. A vertical left screw rod 111 is arranged inside the left U-shaped slide rail 11, and a vertical right screw rod 121 is arranged inside the right U-shaped slide rail 12. The left U-shaped slide rail 11 and the right U-shaped slide rail 12 refer to slide rails with a U-shaped cross section, and when in use, the opening of the left U-shaped slide rail 11 faces to the right, and the opening of the right U-shaped slide rail 12 faces to the left.
A left transmission rod 311 is inserted into the left bottom branch pipe 31, and a right transmission rod 321 is inserted into the right bottom branch pipe 32. The right end of the left driving rod 311 is provided with a left driven bevel gear 3111, and the left end of the right driving rod 321 is provided with a right driven bevel gear 3211.
The inner end of the drive shaft 40 is provided with a drive bevel gear 41.
More specifically:
the lower ends of the left U-shaped slide rail 11 and the right U-shaped slide rail 12 are respectively fixed on the left leg 71 and the right leg 72. Generally, the lower ends of the left and right U-shaped rails 11 and 12 are vertically fixed to the middle portions of the left and right legs 71 and 72, respectively.
The left end of the left bottom branch pipe 31 is generally vertically fixed to the middle of the left leg 71 and the right end of the right bottom branch pipe 32 is generally vertically fixed to the middle of the right leg 72.
The left and right ends of the bed body 20 are respectively provided with a left slide block 21 and a right slide block 22. The left slider 21 and the right slider 22 are provided with screw holes. The screw holes on the left slider 21 and the right slider 22 are respectively screwed with the left lead screw 111 and the right lead screw 121 to form a lead screw nut mechanism, and the left slider 21 and the right slider 22 are respectively clamped in the left U-shaped slide rail 11 and the right U-shaped slide rail 12.
The lower end of the left screw 111 is connected to the left end of the left transmission rod 311 by a left bevel gear pair 60, and the lower end of the right screw 121 is connected to the right end of the right transmission rod 321 by a right bevel gear pair (not shown). That is, a 90 ° transmission of torque is achieved by the bevel gear pair.
The left driven bevel gear 3111 is engaged with the driving bevel gear 41 to form a bevel gear pair, and the right driven bevel gear 3211 is engaged with the driving bevel gear 41 to also form a bevel gear pair. That is, the torque is transmitted through 90 ° by the bevel gear pair, and the left screw 111 and the right screw 121 are synchronously operated.
The motor 50 is in powered connection with the outer end of the drive shaft 40. Obviously, the driving shaft 40 may be a power take-off shaft of the motor 50; alternatively, the power take-off shaft of the motor 50 is connected to the outer end of the drive shaft 40 through a speed reduction mechanism. Of course, the motor 50 is electrically connected to a power source through a switch, and the motor 50 may also be provided with a remote controller for controlling the speed.
The left leg 71 and the right leg 72 are both provided with rollers 80. Typically, at least one of the rollers 80 is equipped with a brake.
The action process of the invention is as follows: the motor 50 drives the driving shaft 40 to rotate, and then the left screw rod 111 and the right screw rod 121 rotate to drive the bed body 20 to move up and down. So, not only adjust accurate, convenient operation is laborsaving, and comparatively safe during the use.
