背景技术Background technique
现今人们的“坐”健康问题日益凸显，为了使解决久坐给人体带来的健康问题，开发了多种休闲椅、按摩椅、零重力沙发和具有多种姿势和功能变换的功能沙发。其中多功能电动沙发具有较大的应用前景。多功能沙发或座椅可以实现从坐姿、休闲到躺姿的平稳变换，满足坐、休闲、睡眠等多种要求。较之传统的沙发有更大的优越性。多功能沙发在设计时运用人机工程学、平面杆系运动学等方法结合，使沙发的舒适性更高。功能沙发的使用有利于身体的血液循环，随时保护我们的身体健康。Nowadays, people's "sitting" health problems are becoming more and more prominent. In order to solve the health problems caused by sitting for a long time, a variety of leisure chairs, massage chairs, zero-gravity sofas and functional sofas with various postures and functions have been developed. Among them, the multifunctional electric sofa has a great application prospect. The multi-functional sofa or seat can realize a smooth transformation from sitting, leisure to lying position, and meet various requirements such as sitting, leisure and sleep. Compared with traditional sofas, it has greater advantages. The multi-functional sofa is designed with a combination of ergonomics, plane rod kinematics and other methods to make the sofa more comfortable. The use of functional sofa is conducive to the blood circulation of the body and protects our health at any time.
作为休闲时首选的沙发座椅，如果设计不合理，不仅起不到放松、缓解疲劳的效果，还将导致腰肌劳损、累积性创伤疾患等多种疾病。为满足使用者的功能需求和使用舒适度，设计结构稳固、运动平稳性好、运动过程中速度和角度平稳的沙发联动支架装置是必要的。As the preferred sofa seat for leisure, if the design is unreasonable, it will not only fail to relax and relieve fatigue, but also lead to various diseases such as lumbar muscle strain and cumulative trauma disorders. In order to meet the user's functional requirements and use comfort, it is necessary to design a sofa linkage bracket device with stable structure, good movement stability, and stable speed and angle during movement.

本实施例的运动原理是驱动电机61驱动丝杠62旋转，从而带动滑动件24沿着滑轨21往复运动，以带动与滑动件24相连的第二连动杆23和与滑轨21的一端相连的第一连动杆22产生旋转和平移运动，最终带动两侧的伸展支架3伸展和收缩。The motion principle of this embodiment is that the driving motor 61 drives the lead screw 62 to rotate, thereby driving the sliding member 24 to reciprocate along the sliding rail 21 to drive the second link rod 23 connected to the sliding member 24 and one end of the sliding rail 21 The connected first linkage rods 22 generate rotational and translational motions, and finally drive the extension brackets 3 on both sides to expand and contract.
本发明沙发联动装置三种姿态的变换。坐姿状态，此时伸展支架3收缩至极限状态，靠背机构31和腿部伸展机构33均收拢于中间座板联动机构32，此时所述第一连动杆22和第二连动杆23距离最近。如图3所示，休闲姿态，此时靠背机构31保持坐姿时的角度基本不变，腿部伸展机构33向前展开到搁脚部与地面平行，在驱动电机的驱动下滑动件24带动第二连动杆23向前平移，第一连动杆22旋转一定角度并向前平移。如图4所示，躺姿状态，在休闲姿的基础上座板联动机构32带动腿部伸展机构33继续向前平移，同时靠背机构31向后倾倒，此时所述第一连动杆22和第二连动杆23之间距离最远。Transformation of three postures of the sofa linkage device of the present invention. In the sitting position, the extension bracket 3 is retracted to the limit state, the backrest mechanism 31 and the leg extension mechanism 33 are both retracted in the middle seat plate linkage mechanism 32, at this time, the first linkage rod 22 and the second linkage rod 23 are separated from each other. recent. As shown in Fig. 3, in the leisure posture, the angle of the backrest mechanism 31 when maintaining the sitting posture is basically unchanged, the leg extension mechanism 33 is extended forward until the footrest is parallel to the ground, and the sliding member 24 drives the first The second linkage rod 23 translates forward, and the first linkage rod 22 rotates at a certain angle and translates forward. As shown in FIG. 4 , in the lying position, the seat plate linkage mechanism 32 drives the leg extension mechanism 33 to continue to translate forward, while the backrest mechanism 31 is tilted backward. At this time, the first linkage rod 22 and the The distance between the second interlocking rods 23 is the farthest.
本发明两伸展之架之间设置有滑动机构和驱动机构，其中驱动机构控制滑动件带动第一连动杆和第二连动杆运动，以使得两个伸展支架伸展或收缩，其中驱动电机与丝杠滑轨结合的驱动方式结构简单、精确度高、降低噪音、节约成本、便于精密控制。本发明驱动电机的一端通过第一转轴与第一连动杆转动连接，第一连动杆与腿部伸展机构连接，伸展支架运动中驱动电机是随第一连动杆向前平移运动的，整个驱动机构的重心在沙发座椅的前端，使得人坐在沙发上时腿部伸展机构的伸展和收缩更加自如和平稳，避免产生晃动的情况。本发明第一连动杆设置在两个座板联动机构之间，第二连动杆设置在两个腿部伸展机构之间，既可以通过第一连动杆和第二连动杆的运动分别驱动座板联动机构和腿部伸展机构的运动，还起到了支撑和平稳装置的作用。A sliding mechanism and a driving mechanism are arranged between the two extending frames of the present invention, wherein the driving mechanism controls the sliding member to drive the first linkage rod and the second linkage rod to move, so as to extend or contract the two extending frames, wherein the driving motor is connected to the The drive mode combined with the screw and slide rails is simple in structure, high in accuracy, reduces noise, saves costs, and is convenient for precise control. In the present invention, one end of the drive motor is rotatably connected with the first linkage rod through the first rotating shaft, the first linkage rod is connected with the leg extension mechanism, and the drive motor moves forward in translation with the first linkage rod during the movement of the stretching bracket. The center of gravity of the entire driving mechanism is at the front end of the sofa seat, which makes the extension and contraction of the leg extension mechanism more free and stable when a person sits on the sofa, and avoids shaking. In the present invention, the first linking rod is arranged between the two seat plate linking mechanisms, and the second linking rod is arranged between the two leg extension mechanisms. The movement of the first linking rod and the second linking rod can It drives the movement of the seat plate linkage mechanism and the leg extension mechanism respectively, and also plays the role of a supporting and stabilizing device.
