最佳实施例 Best embodiment

下面结合一具体实施例来阐述本发明： The invention will now be described in connection with a specific embodiment:

如图 4-11所示，五功能医疗床的机械结构由五块床板拼接而成，分别为背板、座板、活动座板、腿板、脚板，各板之间为铰接方式连接，即彼此可进行相对转动。在驱动电机及控制电路作用下，可自主完成床身倾斜、提升、半卧及座椅状态的转变，不仅方便病人在没有人员护理的情况下自主变换姿态，且为医护人员对病人的检查操作提供了便捷。床身的各种姿态转换给病人带来了很大的舒适感，有效帮助病人进行必要的肢体活动。床体两侧有护栏装置，护栏上有固定装置，可人为操作升降; 采用的脚轮装置有刹车结构，必要时可将医疗床任意转移位置并锁定；五块床板中，只有座板与床架是固定连接，其余床板为活动连接；由于结构设计的特殊性，床身状态的变化符合人体骨骼屈伸需要，给病人带来舒适感。 As shown in Figure 4-11, the mechanical structure of the five-function medical bed is composed of five bed plates, which are respectively a back plate, a seat plate, a movable seat plate, a leg plate and a foot plate, and the plates are hingedly connected, that is, Relative rotation is possible with each other. Under the action of the drive motor and the control circuit, the bed tilting, lifting, half-sleeping and seat state changes can be completed autonomously, which not only facilitates the patient to change the posture autonomously without the person's care, and also checks the patient's operation for the medical staff. Provides convenience. The various postures of the bed bring great comfort to the patient, effectively helping the patient to perform the necessary physical activities. There are guardrail devices on both sides of the bed, and there are fixing devices on the guardrail, which can be manually operated and lowered; the caster device used has a brake structure, and the medical bed can be transferred and locked at any time if necessary; among the five bed plates, only the seat plate and the bed frame Is a fixed connection, the rest of the bed is an active connection; due to the special design of the structure, The change in the state of the bed conforms to the flexion and extension of the human body and provides comfort to the patient.

五功能医疗床五块床板中，只有座板是固定部件，其他四块床板的不同运动形式完成了床身形态的转变，达到各种折叠形式。 Among the five bed plates of the five-function medical bed, only the seat plate is a fixed part, and the different movement forms of the other four bed plates complete the transformation of the bed form to achieve various folding forms.

如图 10所示，医疗床共由四个驱动电机作用，采用中国无锡飞亚机电设备公司生产的 FYK012系列电机控制器和驱动电机，驱动电机具体参数如下：输入电压： 24V DC; 最大负载： 6000N;在承受不同最大负载时有三种速度且可调： 4mm/s ( 6000N )、 13mm/s (2000N)、 16mm/s (2000N)。其中电机 1、 4位于脚轮框架中，驱动相应部件完成床身的提升；另外两个电机 2、 3安装于床架中（床架与五块床板直接相连），完成活动床板的折叠运动，电机 4驱动活动座板和腿、脚板的联动机构，电机 2驱动背板运动，参见图 7。 As shown in Figure 10, the medical bed is operated by four drive motors. The FYK012 series motor controller and drive motor produced by China Wuxi Feiya Electromechanical Equipment Co., Ltd. are used. The specific parameters of the drive motor are as follows: Input voltage: 24V DC; Maximum load: 6000N; three speeds are adjustable when subjected to different maximum loads: 4mm/s (6000N), 13mm/s (2000N), 16mm/s (2000N). The motors 1 and 4 are located in the caster frame, and the corresponding components are driven to complete the lifting of the bed; the other two motors 2, 3 are installed in the bed frame (the bed frame is directly connected with the five bed plates), and the folding movement of the movable bed plate is completed, the motor 4 Drive the movable seat plate and the linkage mechanism of the legs and legs, and the motor 2 drives the back plate movement, see Figure 7.

( 1 ) 提升运动（包括水平提升和床面的倾斜运动） (1) Lifting exercise (including horizontal lifting and tilting movement of the bed)

如图 10示，提升运动主要由电机 1、 4完成，这两个电机均安装于脚轮框架中，电机一端与脚轮框架铰接，另一端由各自的电机杆与框架铰接。其中，电机 1的电机杆直接作用于推杆内管 13，电机 4的电机杆作用于推杆外管 12。推杆内外管在两电机力的推动作用下，通过与之相连的其它杆件将电机力传递于床架，实现床身的提升运动。当两个电机同时运动时可实现床身的平稳提升；当两电机不同时运动，或驱动力矩不相同时，可完成床身头部和脚部的倾斜运动。 As shown in Fig. 10, the lifting movement is mainly performed by the motors 1, 4, both of which are mounted in the caster frame, one end of the motor is hinged to the caster frame, and the other end is hinged to the frame by the respective motor rod. The motor rod of the motor 1 directly acts on the inner tube of the push rod 13, and the motor rod of the motor 4 acts on the outer tube 12 of the push rod. Under the action of the two motor forces, the inner and outer tubes of the push rod transmit the motor force to the bed frame through other rods connected thereto, thereby realizing the lifting movement of the bed. When the two motors move at the same time, the bed can be smoothly lifted; when the two motors are not moving at the same time, or the driving torque is different, the tilting movement of the head and the foot of the bed can be completed.

(2) 半卧状态 (2) Half-sleeping state

半卧状态和座椅状态的实现有相似运动过程，如图 7示：其中背板的折叠运动主要由电机 2驱动，活动座板及腿脚板的联动动作由电机 3驱动完成。 The implementation of the semi-recumbent state and the seat state has a similar motion process, as shown in Figure 7: The folding movement of the backboard is mainly driven by the motor 2, and the interlocking action of the movable seat plate and the legboard is driven by the motor 3.

当驱动电机 2时，电机力通过背板折合管拨叉片的传递实现背板绕座板固定铰接点的旋转运动，从而完成背板的折叠。与此同时，电机 3驱动摆杆部件，完成腿板向下折叠，由于机构间的特殊连接方式使得脚板与腿板同步弯曲，同时活动座板有相应上翘动作。整个过程由医疗床的控制电路完成，实际操作只需按下半卧状态的按钮即可使床身状态达到病人舒适度要求。 When the motor 2 is driven, the motor force is transmitted through the back plate folding pipe fork piece to realize the rotation movement of the back plate around the fixed hinge point of the seat plate, thereby completing the folding of the back plate. At the same time, the motor 3 drives the swing member to complete the folding of the leg plate. Due to the special connection between the mechanisms, the foot plate and the leg plate are simultaneously bent, and the movable seat plate has a corresponding upward movement. The whole process is completed by the control circuit of the medical bed. In actual operation, the button state can be pressed to achieve the patient comfort requirement by pressing the button of the semi-recumbent state.

(3 ) 座椅状态 (3) Seat status

如图 7所示，座椅状态的实现过程与半卧状态相似，只是需要控制电机 2、 3驱动时间加长，使得背板倾斜角度加大，同时腿板与水平面成 90度夹角，脚板呈水平状态。 As shown in Fig. 7, the realization state of the seat state is similar to that of the semi-recumbent state, except that it is necessary to control the driving time of the motor 2, 3 to be lengthened, so that the inclination angle of the back plate is increased, and the leg plate is at an angle of 90 degrees with the horizontal plane, and the foot plate is Horizontal status.

即当驱动电机 2时，电机力通过背板折合管拨叉片的传递实现背板绕座板固定铰接点的旋转运动，从而完成背板的折叠。与此同时，电机 3驱动摆杆部件，完成腿板向下折叠，由于机构间的特殊连接方式使得脚板与腿板同步弯曲，同时活动座板上翘。同样的，此过程由医疗床的控制电路完成，实际操作时只需按下座椅状态的按钮即可。 That is, when the motor 2 is driven, the motor force is transmitted through the back plate folding pipe fork piece to realize the rotation movement of the back plate around the fixed hinge point of the seat plate, thereby completing the folding of the back plate. At the same time, the motor 3 drives the swing lever member to complete the downward folding of the leg plate, and the foot plate and the leg plate are simultaneously bent due to the special connection between the mechanisms, and the movable seat plate is tilted. In the same way, the process is completed by the control circuit of the medical bed, and in actual operation, it is only necessary to press the button of the seat state.

其它如图 5、 6、 8、 9所示的各种使用状态动作过程和原理与上述三种状态运作相似，都是电机带动相应床板或框架运动，以形成不同的使用形态。 Other operating states and principles of the various states of use shown in Figures 5, 6, 8, and 9 are similar to those of the above three states, in that the motor drives the corresponding bed or frame motion to form different modes of use.

其中如图 11所示，是本发明中该实施例的脚轮框架单独的结构展示，可明显看出脚轮框架与床板结构的安装对应关系和相应结构构造。 Wherein, as shown in FIG. 11, is a separate structure of the caster frame of the embodiment of the present invention. The display shows the corresponding correspondence between the caster frame and the bed structure and the corresponding structural structure.

其中如图 3所示，脚板支撑杆是外观呈 U形的单一杆件，安装于脚板下方，与脚板通过活动连接轴和扭簧连接，其相对于床板的可转动范围为 0-90度，脚板支撑杆的高度是电动床为平卧状态时床面板与床体底架的高度。当床身呈平卧状态时，脚板支撑杆在扭簧的作用下下垂，即与水平面成 90度,支撑脚板与脚轮框架间的间隙，当床身变换为座椅状态时，脚板会直接搭在脚轮框架上，由于支撑杆与脚板间是活动铰链连接，支撑杆相对脚板转动。本设计新颖、简便、实用，完全解决了医用电动床床体各功能合理使用时所存在的床面板悬空、床体弯曲倾斜等问题。 As shown in FIG. 3, the foot support rod is a single rod having a U-shaped appearance, and is mounted under the foot board, and is connected with the foot board through a movable connecting shaft and a torsion spring, and the rotation range thereof is 0-90 degrees with respect to the bed board. The height of the foot support rod is the height of the bed panel and the bed frame when the electric bed is in a flat state. When the bed is in a flat state, the support bar of the foot hangs under the action of the torsion spring, that is, 90 degrees from the horizontal plane, and the gap between the support plate and the caster frame is supported. When the bed is changed to the seat state, the foot plate will directly take the foot On the caster frame, the support bar rotates relative to the foot plate due to the active hinge connection between the support bar and the foot plate. The design is novel, simple and practical, and completely solves the problems of the hanging of the bed panel and the tilting of the bed when the functions of the medical electric bed body are reasonably used.

需要注意的是，尽管本发明已参照具体实施方式进行描述和举例说明，但是并不意味着本发明限于这些描述的实施方式，本领域技术人员可以从中衍生出许多不同的变体，它们都将覆盖于本发明权利要求的真实精神和范围中。 It is to be noted that the invention has been described and illustrated by reference to the specific embodiments thereof, which are not to be construed as limited The true spirit and scope of the claims of the invention are covered.
