The specific embodiment
As shown in Figures 1 to 4, the front motor drives structure of beddo of the present invention comprise mutually between a hinged back bed board 1 and fixed bed board 2, upper frame 3, underframe 4 and with the front motor 5 of drive rod 51, described upper frame 3 comprises two side levers 31, two cross bars 32 and four guiding mechanisms 33, described two side levers, 31 parallel interval are arranged and two ends bending has a downwarp, described two cross bar 32 spaced and parallel are located between described two side levers 31, described four guiding mechanisms 33 are located at respectively the two ends of described two side levers 31, described two cross bars 32 are located at described fixed bed board 2 bottom surfaces, described upper frame 3 one end extend to described back bed board 1 below, described underframe 4 comprises that rectangle frame 41, middle brace rod 42, the first ear climb 44 and four short lead rail 43, described middle brace rod 42 levels are located in described rectangle frame 41, described the first ear is climbed 44 and is located on described middle brace rod 42, described four short lead rail 43 are located at respectively described rectangle frame 41 inner sides, two ends, and four guiding mechanisms 33 of described upper frame 3 lay respectively in four short lead rail 43 of described underframe 4, this drives structure also comprises front motor support 6 and linear bearing assembly 7,
Wherein: described front motor support 6 comprises that swingle 61, two connecting rods 62 and the second ear climb 63, described swingle 61 is horizontally hinged between two side levers 31 of described upper frame 3 one end, described two connecting rod 62 perpendicular separations are located on described swingle 61, and described the second ear is climbed 63 and is located at described swingle 61 bottom surfaces;
Described linear bearing assembly 7 comprises base 71, two sides 72, two linear bearings 73 and two bases 74, described two sides 72 are located at respectively 71 two ends, described base, described two linear bearing 73 one end respectively interval are vertical on described base 71, described two bases 74 are located at respectively described two linear bearing 73 other ends, described base 71, two sides 72 and two bases 74 are located at respectively described back bed board 1 bottom surface, two connecting rods 62 hinged described two linear bearings 73 respectively of described front motor support 6;
It is 44 hinged that described front motor 5 and the first ear on described underframe 4 middle brace rods 42 are climbed, and it is 63 hinged that the second ear on drive rod 51 tops of described front motor 5 and described front motor support 6 swingles 61 is climbed.
Further, the second ear of above-mentioned front motor support 6 climb 63 be arc ear climb and arc towards described front motor 5 directions.What arc ear was climbed is arranged so that when front motor drives swingle rotation to have the longer arm of force, so just can produce larger moment with the motor of smaller power, thereby makes front motor enough drive swingle rotation.
Further, four of above-mentioned upper frame 3 guiding mechanisms 33 are directive wheel or guide runner.Directive wheel or guide runner have good guide effect in the guide rail of underframe, make upper frame more reliable with being flexibly connected of underframe.
Further, two of above-mentioned upper frame 3 cross bars 32 are located at described fixed bed board 2 bottom surfaces by screw.
