AI Technical Summary
Existing furniture and chairs lack effective shock absorption structures, resulting in insufficient cushioning of the impact force when users sit down or stand up. This can easily damage the chair structure after prolonged use, affecting its lifespan and comfort.
Multiple support damping columns are set between the chair base and the seat cushion, and a lower shock absorber and an upper shock absorber are installed between the base and the seat cushion. The lower shock absorber consists of a fixed rod, a slider and a spring. The cushioning is achieved through the sliding connection between the slider and the fixed rod and the rotational connection of the movable support rod. The backrest angle is adjusted in conjunction with the electric telescopic rod and control buttons.
Effective cushioning and vibration reduction enhance user comfort, prevent structural damage to the chair, extend its service life, and improve the chair's structural practicality and functionality.

Technical Field
[0001] This utility model relates to the field of furniture and chair technology, specifically to a furniture and chair with a vibration damping structure. Background Technology
[0002] Chairs are a common piece of furniture in people's daily lives, and their design involves not only comfort but also aesthetics, functionality, and materials science. Chairs have a long tradition in history, culture, and function, evolving from simple seating to various styles and uses today. The earliest chairs can be traced back to ancient Egypt around 3000 BC. At that time, chairs were generally made of wood or stone and were mainly used by nobles and the ruling class. Ancient chair designs were mostly simple and sturdy, often without cushions. In medieval Europe, chairs gradually became a symbol of the aristocracy. Chairs at that time were usually very tall, and their designs emphasized symbolism rather than comfort. For example, church or royal chairs were often exquisitely carved, carrying religious or political symbolism. With the arrival of the Renaissance, chair designs began to focus more on comfort and aesthetics, resulting in more decorative and ergonomic designs. The Industrial Revolution of the 19th century enabled large-scale furniture production, and chair production became more refined and diverse, leading to their widespread adoption in homes and workplaces.
[0003] The existing technology has the following problems:
[0004] Existing furniture and chairs have relatively simple overall structures and limited functionality, generally only providing seating. Current furniture and chairs lack good shock absorption structures, making it difficult to provide users with better comfort. At the same time, due to the lack of cushioning and shock absorption structures, the impact force generated when a person sits down or stands up during use cannot be effectively buffered. After prolonged use, the structure of the chair is easily damaged, affecting its lifespan. Utility Model Content
