As shown in fig. 1 to 5, the end of the support assembly 2 near the bed tail 4 is provided with a stopper 20, and the stopper 20 is used for restricting the movement of the mattress on the support assembly 2 along the length direction of the bed of the electric bed when the back support 22 and the waist support 23 are turned upwards.

Through the restriction of locating part 20 to the mattress, guaranteed the stability that the mattress set up on supporting component 2, need not to adjust the position of mattress on supporting component 2 after using back support piece 22 and waist support piece 23, be favorable to making things convenient for the use of electric bed.

For the limiting member 20, in this embodiment, the limiting member 20 is a U-shaped limiting rod. By this arrangement, the weight of the stopper 20 can be reduced, and the weight of the electric bed can be reduced.

In another embodiment, the stop 20 is a stop plate. The structure of the limiting piece 20 can be simplified, and the processing and manufacturing of the limiting piece 20 are facilitated.

In other embodiments, the stop 20 may not be provided, in which case the mattress may be attached to the support assembly 2 by straps to ensure stability of the mattress on the support assembly 2. By the arrangement, the structural arrangement on the support component 2 can be simplified, and the processing and manufacturing of the support component 2 are facilitated.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and not for limiting the same; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the application.
