Description

Technical Field

[0001] The utility model relates to the technical field of seat equipment, in particular to a novel seat chassis. Background Art

[0002] The seat chassis is the core part of the seat structure, which is mainly used to support the main body of the seat and connect various functional components, such as adjustment mechanisms, wheels and seat frames. The design of the seat chassis and the selection of materials play a vital role in the stability, durability and functionality of the seat. In modern seat design, the chassis is usually made of metal (such as steel or aluminum), plastic or composite materials to ensure sufficient strength and lightness. The design of the seat chassis also takes ergonomics into consideration to provide sufficient support and comfort. In addition, many seat chassis are equipped with adjustable mechanisms, such as height adjustment, tilt and rotation functions to meet the needs of different users. In many fields such as office, medical, automotive and aviation, the design and technology of the seat chassis are different to adapt to various specific application environments and usage requirements.

[0003] Existing seat designs mostly use materials such as metal compression springs, torsion springs, manganese steel plates and glass fibers. Although these materials have advantages in cost and manufacturing, they may not be sufficient to meet the needs of multi-function and high adaptability in terms of flexibility, adjustability and durability. To solve this problem, new synthetic materials or improved metal alloys, such as memory alloys and high-performance polymers, can be considered. These materials can provide better mechanical properties and long-term reliability.

[0004] Secondly, traditional seat designs often use mechanical locking mechanisms, which usually have fixed locking positions. Users cannot adjust the reclining angle as needed, which limits the possibility of personalized settings. Improved technologies may include the use of continuously variable locking systems, such as friction locks or electromagnetic locking mechanisms. These technologies can achieve precise locking at any angle, providing a more personalized and comfortable user experience.

[0005] Furthermore, in traditional chairs, the reclining force is often fixed and will not be automatically adjusted according to the weight of the person sitting on it, which may lead to large differences in user experience for people of different weights. To overcome this, an intelligent sensing system can be designed to sense the user's weight through sensors and automatically adjust the reclining force. For example, a pressure sensor and a microcontroller can be used to dynamically adjust the response of a gas spring or electric motor to ensure that each user can get the support force that suits their weight.

[0006] Finally, in traditional seats, the interactive feeling of the seats is relatively hard, which may be caused by the rigidity of the material or the lack of ergonomic design. To improve this, more advanced cushioning and shock absorption technologies can be introduced, such as using gel pads, high-density foam or new elastic materials. These materials can better adapt to the user's body shape and movement, providing a more comfortable and responsive sitting experience. Utility Model Content

[0007] In order to make up for the above deficiencies, the utility model provides a novel seat chassis, aiming to improve the problem that the equipment cannot provide better mechanical properties.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a new type of seat chassis, including a detachable seat bracket, a plurality of buffer pads are fixedly connected to the bottom of the detachable seat bracket, the bottoms of the buffer pads are all fixedly connected, the bottoms of the buffer pads are all fixedly connected to a load-bearing frame, the inside of the load-bearing frame is rotatably connected with a rotating joint part, one side of the rotating joint part is rotatably connected with a gas spring buffer, a chassis body is arranged at the bottom of the detachable seat bracket, the gas spring buffer is arranged inside the chassis body, a locking gas spring is arranged on one side of the gas spring buffer on the left side, an internal rotation mechanism is arranged at one end of the gas spring buffer, the outer wall of the chassis body is rotatably connected with a connecting tail plate, the top of the chassis body is fixedly connected with a chassis cover, and the top of the chassis body is provided with a control component.

[0009] As a further description of the above technical solution:

[0010] The control component comprises an air pipe, the air pipe is arranged inside the air lock spring, the air pipe passes through the rotating joint and extends to the outside, and a controller is arranged at one end of the air pipe.

[0011] As a further description of the above technical solution:

[0012] The buffer pads are distributed in a rectangular array according to the length of the detachable seat bracket, and the gas spring buffers are distributed in a left-right symmetrical manner.

[0013] As a further description of the above technical solution:

[0014] The load-bearing frame is rotatably connected to the interior of the chassis body, and the rotating joint is rotatably connected to the interior of the chassis body.

[0015] The utility model has the following beneficial effects:

[0016] 1. In the present invention, the seat tilt and support strength are automatically adjusted. Such an adaptive mechanism reduces the frequency and complexity of manual adjustment required by users to adapt to the weight and sitting posture of different users, ensuring optimal comfort and support and providing more personalized and comfortable support.

[0017] 2. In the present invention, high-quality gas springs are used to allow users to lock the reclining position of the chair at any angle. This flexibility allows users to customize their sitting posture, whether it requires fine-tuning for the best typing posture or leaning back completely for rest and relaxation, thereby improving the smoothness and precision of the adjustment, and further increasing the durability and reliability of the chair.

[0018] 3. In the present invention, as the reclining angle of the seat increases, the rear part of the seat will be raised accordingly, which can reduce the pressure on the user's legs and tail and increase the comfort of the lower limbs. This dynamic geometric adjustment helps to maintain blood circulation and reduce the discomfort or fatigue that may be caused by sitting for a long time, so that the seat can provide continuous support and comfort for people of all body types.

[0019] 4. In the present invention, the seat can provide progressive support through components such as cushions to avoid the impact caused by hard contact. This cushioning effect not only reduces the impact of the seat on the body, but also reduces the long-term damage to the seat structure caused by sudden sitting down. This design provides additional protection especially for users with sensitive waist and back problems or potential problems. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 , an embodiment provided by the utility model: a new type of seat chassis, including a detachable seat bracket 1, a plurality of buffer pads 2 are fixedly connected to the bottom of the detachable seat bracket 1, the bottom of the buffer pads 2 are all fixedly connected, the bottom of the buffer pads 2 are all fixedly connected to a load-bearing frame 6, the inside of the load-bearing frame 6 is rotatably connected with a rotating joint 5, one side of the rotating joint 5 is rotatably connected with a gas spring buffer 7, a chassis body 9 is arranged at the bottom of the detachable seat bracket 1, the gas spring buffer 7 is arranged inside the chassis body 9, a locking gas spring 12 is arranged on one side of the left gas spring buffer 7, an inner rotation mechanism 8 is arranged at one end of the gas spring buffer 7, the outer wall of the chassis body 9 is rotatably connected with a connecting tail plate 3, the top of the chassis body 9 is fixedly connected with a chassis cover 4, the top of the chassis body 9 is provided with a control component, the buffer pads 2 are distributed in a rectangular array according to the length of the detachable seat bracket 1, the gas spring buffer 7 is symmetrically distributed, the load-bearing frame 6 is rotatably connected to the inside of the chassis body 9, and the rotating joint 5 is rotatably connected to the inside of the chassis body 9;

[0031] Specifically, the detachable seat bracket 1 provides basic support, and the cushion pad 2 is located at the bottom of the seat bracket. They are distributed in a rectangular array to absorb and mitigate the impact force generated when the user sits down. At this time, the load-bearing frame 6 is immediately below the cushion pad 2 to provide additional structural strength to support the weight of the entire seat. At the same time, the rotating joint 5 can be rotated, which allows the joint to be fine-tuned when the user changes the sitting posture. These joints rotate axially around their mounting points in response to the user's movement. Then the gas spring buffer 7 is connected through these rotating joints 5 and can expand or compress when the user leans back. It can adapt to different sitting posture requirements by adjusting the internal gas. While the locking gas spring 12 is operating at a fixed angle, the internal rotation mechanism 8 can cooperate to control the fine adjustment of the reclining angle. This mechanism responds to the user's weight and movement, and automatically adjusts the tilt force and angle of the seat. The chassis body 9 cooperates with the chassis cover 4 to provide additional structural support and protection. The gas spring buffer 7, the internal rotation mechanism 8 and the chassis body 9 are all driven by the gas spring, and the angle change and force are driven by the connecting rod. The air pipe 10 passes through the rotating joint 5 and is connected to the locking gas spring 12, allowing the user to operate various dynamic adjustment functions of the seat through the controller 11. The quadrilateral shape composed of the tail plate 3, the load-bearing frame 6, the gas spring buffer 7 and the internal rotation mechanism 8 has four fulcrums that are not fixed and can change with the force of the multi-link. The corresponding rotating joint 5 and the load-bearing frame 6 are offset through the fulcrum. After the force is applied, the corresponding rear angle force increases, and the weight changes adaptively.

[0032] Reference Figure 3 and Figure 4 The control component includes an air pipe 10, which is arranged inside the air lock spring 12, and the air pipe 10 passes through the rotating joint 5 and extends to the outside. A controller 11 is arranged at one end of the air pipe 10;

[0033] Specifically, through the controller 11, the user can accurately adjust the air pressure in the air pipe 10, thereby controlling the pressure of the air locking spring 12, and ensuring that the angle of the seat remains stable when needed; the air pipe 10 is an important component connecting the controller 11 and the air locking spring 12. The air pipe 10 has a control steel cable inside and is wrapped with outer rubber to ensure that the air pipe 10 has sufficient strength and flexibility to cope with various pressure changes during seat adjustment and ensure fast and smooth transmission of gas.

[0034] Working principle: When the user sits down, the body weight first affects the cushion 2 through the detachable seat bracket 1, and then transmits the pressure to the rotating joints 5 through the load-bearing frame 6. These rotating joints 5 begin to change their positions, that is, they rotate around their installation center axes, and adjust the inclination and elasticity of the seat according to the pressure they receive. When the user leans back, the gas spring buffer 7 automatically adjusts the length and pressure according to the leaning back force, and accurately controls the angle adjustment through the internal rotation mechanism 8 to adapt to the user's body shape and preference. At the same time, the user can operate the controller 11 to adjust the locking state of the locking gas spring 12 through the air pipe 10, thereby locking the inclination of the seat at any angle, whether it is a relaxed backrest or a formal sitting posture.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
