High, especially when people are lying on one side of the bed, the hinge will be biased toward the side on which the person lies, easily breaking or bending the drive end of the drive motor.
受此影响，现有的腰部顶出机构容易受到扭矩影响而降低使用寿命。Affected by this, the existing waist ejecting mechanism is susceptible to torque and reduces the service life.
此外，现有的腰部顶出机构在顶出腰部床板时，腰部床板顶出的高度受制于腰部床板的宽度，并且在顶出时与床垫产生摩擦。In addition, the existing waist ejecting mechanism, when ejecting the waist deck, the height of the waist deck ejected is limited by the width of the lumbar deck and rubs against the mattress when ejected.
受此影响，现有的腰部顶出机构在机构设计上具有较大的限制不能很好地贴近腰部的位置，也容易造成床垫磨损。Affected by this, the existing waist ejecting mechanism has a large limitation in the design of the mechanism, and the position of the waist is not well close to the waist, and the mattress is easily worn.

更具体的，当驱动电机驱动耳攀32而带动调节元件3的主体30在平行导轨22中移动时，每个连杆5将随着与其铰接的延伸臂31的位置变化而绕着第一铰接轴X转动，并带动延伸臂31转动，与此同时，调节元件3的主体30跟随延伸臂31的转动发生自转，如此调节腰部顶出杆4在竖直方向上的高度。More specifically, when the driving motor drives the ear catch 32 to drive the main body 30 of the adjusting member 3 to move in the parallel rail 22, each of the links 5 will follow the first hinge axis as the position of the extending arm 31 hinged thereto is changed. X rotates and drives the extension arm 31 to rotate, while at the same time, the main body 30 of the adjustment member 3 rotates following the rotation of the extension arm 31, thus adjusting the height of the waist ejecting lever 4 in the vertical direction.
更具体的，每个连杆5铰接在与其相对应的延伸臂31的总长度三分之一到三分之二之间，这样通过调节元件3的移动运动和连杆5的枢转运动，使得腰部顶出杆4能够实现接近于直上直下的运动关系，更有利于对床垫的保护。More specifically, each link 5 is hinged between one third and two thirds of the total length of the extension arm 31 corresponding thereto, such that by the movement of the adjustment member 3 and the pivotal movement of the link 5, The waist ejector rod 4 can be made to be close to the straight up and down movement relationship, which is more conducive to the protection of the mattress.
可选的，每个连杆5的长度是与其相对应的延伸臂31总长度的三分之一到三分之二之间，这样通过调节元件3的移动运动和连杆5的枢转运动，使得腰部顶出杆4能够实现接近于直上直下的运动关系，更有利于对床垫的保护。Optionally, the length of each link 5 is between one third and two thirds of the total length of the extension arm 31 corresponding thereto, such that the movement of the adjustment member 3 and the pivotal movement of the link 5 are achieved. In this way, the waist ejecting rod 4 can achieve a movement relationship close to straight up and down, which is more conducive to the protection of the mattress.
腰部顶出杆4与每一个延伸臂31相连。在本实施例中，腰部顶出杆4还包括与延伸臂31数量相同的套筒41，每个套筒套41在一个延伸臂31的外围并且在套筒41外表面上具有通孔，通过套筒外表面上的通孔可旋拧螺丝，从而将腰部顶出 杆4与延伸臂31紧固相连。The waist ejector rod 4 is connected to each of the extension arms 31. In the present embodiment, the waist ejector rod 4 further includes a sleeve 41 of the same number as the extension arms 31, each sleeve sleeve 41 having a through hole at the outer periphery of one extension arm 31 and on the outer surface of the sleeve 41, through The through hole on the outer surface of the sleeve can be screwed to push the waist out The rod 4 is fastened to the extension arm 31.
参见图2，本发明的另一方面还涉及一种包括如上所述的腰部顶出机构1的电动床100，其中电动床包括多块床板，以及用于驱动该腰部顶出机构的驱动电机8。如上所述的腰部顶出机构1安装在其中一块床板的下表面。更具体的，安装如上所述的腰部顶出机构1的床板开设有开口101以便使腰部顶出机构的延伸臂穿过，其中腰部顶出机构的腰部顶出杆突出于该床板的下表面。Referring to Fig. 2, another aspect of the present invention is also directed to an electric bed 100 including the waist ejecting mechanism 1 as described above, wherein the electric bed includes a plurality of bed plates, and a drive motor 8 for driving the lumbar ejector mechanism . The waist ejecting mechanism 1 as described above is mounted on the lower surface of one of the bed plates. More specifically, the bed plate on which the waist ejecting mechanism 1 as described above is mounted is provided with an opening 101 for allowing the extending arm of the lumbar ejecting mechanism to pass therethrough, wherein the lumbar ejecting rod of the lumbar ejecting mechanism protrudes from the lower surface of the bed board.
由于该电动床100中安装的腰部顶出机构1具有基座，因此，当腰部顶出杆受到躺在该电动床100上的用户的压力时能够将该压力均匀分散到正规基座中，并通过与该基座相连的床板分散该压力，不会在腰部顶出机构1中产生扭矩，避免了该腰部顶出杆中与驱动电机相连的耳攀损坏的可能性。此外，通过调整延伸臂的长度可以调整腰部顶出机构的顶出高度，能够更加贴近腰部的位置，并且通过调整连杆与延伸臂的长度比例和铰接点的位置能够使得腰部顶出杆实现接近于直上直下的运动关系，更有利于对床垫的保护。Since the waist ejecting mechanism 1 installed in the electric bed 100 has a base, the pressure can be evenly dispersed into the regular base when the waist ejecting rod is pressed by the user lying on the electric bed 100, and Dispersing the pressure by the bed attached to the base does not generate torque in the waist ejecting mechanism 1 and avoids the possibility of damage to the ear climbing of the lumbar ejector lever that is connected to the drive motor. In addition, by adjusting the length of the extension arm, the ejection height of the waist ejecting mechanism can be adjusted to be closer to the position of the waist, and the waist ejecting rod can be made close by adjusting the length ratio of the connecting rod to the extending arm and the position of the hinge point. The straight-down sports relationship is more conducive to the protection of the mattress.
