Description

Bed board height self-adaptive electric bed Technical Field The utility model relates to the technical field of intelligent home, in particular to a bed plate height self-adaptive electric bed. Background In the current society, the modern household and medical care fields are increasingly developed, and the application of the electric bed is also increasingly wide. The adjustable bed board has the unique advantage of being capable of bringing more comfortable and agreeable rest experience for users by virtue of the adjustable bed board height and the adjustable posture. In particular in medical settings, electric beds play a significant role in the care and rehabilitation of patients, the importance of which is self-evident. However, the existing electric bed has a number of problems to be solved in terms of structural design, and these potential defects affect the performance and application to some extent. At present, most electric beds in the market generally adopt driving units with different structures when realizing the functions of adjusting the height of a bed plate and changing the posture. However, the space required by these front driving units with different structures is greatly different during operation and in the storage state. This undoubtedly brings a lot of inconveniences to the product development, because in the product development stage, in order to ensure the normal operation of the driving unit and the smooth storage of the bed body, the distance between the bed plate assembly and the support frame often needs to be repeatedly adjusted for many times. Such a process is not only time consuming and labor intensive, but also greatly reduces development efficiency. In addition, in the traditional electric bed structure, the height adjustment of each part of the bed plate is relatively fixed, and a flexible and effective adjusting mechanism is lacked. This means that when it is necessary to adapt the drive units to different configurations, extensive modifications have to be made to the overall bed structure. Therefore, the complex structure verification work in the product development process is unavoidable, which not only consumes a great deal of time and energy, but also significantly increases the development cost, and greatly prolongs the development period of the product, thereby being in a disadvantageous position in market competition. Disclosure of utility model In view of the above-mentioned drawbacks of the prior art, the present utility model is to provide a bed board height adaptive electric bed, which solves the problems of development cost and development cycle increase caused by difficulty in flexible adjustment of the gap between the support frame and the bed board in the development and verification process of the electric bed in the prior art.
