Or there may also be elements placed in the middle.When an element is considered as " connection " another element, it, which can be, is directly connected to
To another element or it may be simultaneously present centering elements.Term as used herein " vertical ", " horizontal ", " left side ",
" right side " and similar statement for illustrative purposes only, are not meant to be the only embodiment.
Unless otherwise defined, all technical and scientific terms used herein are led with the technology for belonging to the utility model
The normally understood meaning of the technical staff in domain is identical.Terminology used in the description of the utility model herein only be
The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term " and or " used herein packet
Include any and all combinations of one or more related listed items.
As shown in Figure 1, the structure chart of the bed electric pushrod 10 for an embodiment of the present invention.
A kind of with electric pushrod 10, comprising: installation shell 100, the push rod driving portion being mounted in installation shell 100
200 are drivingly connected with push rod driving section 300, push rod driving portion 200 and push rod driving section 300.
Further, push rod driving portion 200 includes: driving motor 210, rotation main shaft 220 and transmission gear 230, driving
Motor 210 and rotation main shaft 220 are drivingly connected, and transmission gear 230 is engaged with rotation main shaft 220.In the present embodiment, driving cog
Wheel 230 is double-layer gear.Using for double-layer gear is more stable when on the one hand can make to be driven work, reduces the generation of noise, separately
