Description
技术领域technical field
本发明涉及一种应用于电动床的腰部顶出机构以及包括该腰部顶出机构的电动床。The invention relates to a waist ejecting mechanism applied to an electric bed and an electric bed comprising the waist ejecting mechanism.
背景技术Background technique
在电动床中设置腰部顶出机构能够提高电动床的调节范围，使电动床更能满足一些腰部不适或腰部损伤的特殊人群的需求。Setting the waist ejecting mechanism in the electric bed can improve the adjustment range of the electric bed, so that the electric bed can better meet the needs of some special people with waist discomfort or waist injury.
现有的腰部顶出机构通常直接通过驱动电机顶出腰部床板；或者通过驱动电机驱动传动件，再由传动件顶出腰部床板；然而，这些设计方式对铰接驱动电机的铰接部的强度要求非常高，尤其是当人们躺在床板一侧时，铰接部将受到偏向人们躺着的这一侧的一个扭矩，容易使驱动电机的驱动端折断或弯曲。The existing waist ejection mechanism usually pushes out the waist bed board directly through the drive motor; or drives the transmission part through the drive motor, and then the transmission part pushes out the waist bed board; however, these design methods have very high requirements on the strength of the hinge part of the hinge drive motor High, especially when people lie on one side of the bed board, the hinge will be subject to a torque biased towards the side where people lie, which will easily break or bend the driving 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 ejection mechanism is easily affected by the 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, when the existing waist ejection mechanism ejects the waist bed board, the height of the waist bed board is limited by the width of the waist bed board, and friction occurs with the mattress during ejection.
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 ejection mechanism has relatively large limitations in mechanism design and cannot be well close to the position of the waist, and it is also easy to cause wear and tear on the mattress.
发明内容Contents of the invention

In this embodiment, the waist ejection rod 4 also includes sleeves 41 having the same number as the extension arms 31, each sleeve sleeve 41 has a through hole on the 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, so that the waist ejector rod 4 is firmly connected with 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 also relates to an electric bed 100 including the waist ejection mechanism 1 as described above, wherein the electric bed includes a plurality of bed boards, and a drive motor 8 for driving the waist ejection mechanism . The above-mentioned waist pushing-out mechanism 1 is installed on the lower surface of one of the bed boards. More specifically, an opening 101 is opened on the bed board on which the waist ejection mechanism 1 is installed so that the extension arm of the waist ejection mechanism can pass through, wherein the waist ejection rod of the waist ejection 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 ejection mechanism 1 installed in the electric bed 100 has a base, when the waist ejection rod is subjected to the pressure of the user lying on the electric bed 100, the pressure can be evenly distributed in the regular base, and The pressure is distributed through the bed board connected with the base, no torque will be generated in the waist ejection mechanism 1, and the possibility of damage to the ear loop connected with the drive motor in the waist ejection rod is avoided. In addition, by adjusting the length of the extension arm, the ejection height of the waist ejection mechanism can be adjusted, which can be closer to the position of the waist, and by adjusting the length ratio of the connecting rod to the extension arm and the position of the hinge point, the waist ejection rod can be closer to the waist. Because of the straight up and down motion relationship, it is more conducive to the protection of the mattress.
