DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 3 The present invention provides an embodiment of a novel office chair chassis, comprising:

[0033] The first metal part 1 and the second metal part 2 of the chassis are connected to the outer wall of the first metal part 1 on one side. The first metal part 1 and the second metal part 2 of the chassis are both used to support the entire chassis. The first metal part 1 provides the main load-bearing support structure of the chassis, and the second metal part 2 is connected to the first metal part 1 by rotation, which can provide a certain rotation angle. This makes the chassis have a certain degree of flexibility and dynamic adjustment capabilities to meet the needs of different work and leisure modes;

[0034] The chassis front support arm 5 is used to support the front of both sides of the first metal member 1 of the chassis. When the seat is in use, the chassis front support arm 5 assumes the front support function of the chassis to ensure the stability of the front of the seat under different load conditions, and cooperates with the lifting gas rod 8 to adjust the comfort and ensure the front and rear balance of the seat;

[0035] The chassis rear support arms 6 are used to provide rear support on both sides of the second chassis metal member 2. The chassis rear support arms 6 balance the chassis front support arms 5 to ensure balanced force on the entire seat chassis and prevent the seat from tilting or becoming unstable during use. In particular, when the seat is shaken or adjusted, the chassis rear support arms 6 provide critical rear support, making the seat more stable.

[0036] The lifting gas rod 8 is provided inside the front support arm 5 and the rear support arm 6 of the chassis. The lifting gas rod 8 is used to adjust the comfort of the office chair. The setting of the lifting gas rod 8 allows the seat to be adjusted in height and tilt angle according to the needs of the user, which increases the flexibility and adaptability of the seat. Through the action of the gas rod, the user can easily adjust the seat's lifting, front and back tilt and other functions, optimize the sitting experience, and reduce fatigue caused by long-term sitting;

[0037] The seat bracket 7 is used to connect the office chair to the chassis. The seat bracket 7 plays the role of connecting the seat to the chassis. It is an important load-bearing component between the seat and the chassis, ensuring the stability of the seat in all directions. One end of the front support arm 5 of the chassis is symmetrically arranged and fixedly connected to the outer wall of the first metal part 1 of the chassis, and one end of the rear support arm 6 of the chassis is symmetrically arranged and fixedly connected to the outer wall of the second metal part 2 of the chassis. This symmetrical design ensures the stability of the seat in the front and back, left and right directions, and improves the overall load-bearing capacity of the chassis.

[0038] Specifically, the first metal part 1 of the chassis is connected to the bottom lifting cylinder. The design of the first metal part 1 of the chassis ensures that it is firmly connected to the cylinder, providing good support and load-bearing capacity. The outer wall of the first metal part 1 of the chassis is connected to the second metal part 2 of the chassis through a rotation design. The second metal part 2 of the chassis can provide a flexible rotation angle within a certain range, so that the entire chassis system can better adapt to the dynamic needs of users and achieve higher maneuverability and comfort. The outer wall of the second metal part 2 of the chassis is supported by the lifting gas rod 8 and the seat bracket 7 in the front support arm 5 of the chassis, so that the chassis can be vertically adjusted. The lifting becomes smoother while ensuring the stability of the seat; similarly, the two sides of the second metal part 2 of the chassis are connected to the seat bracket 7 through the lifting gas rod 8 inside the rear support arm 6 of the chassis, which enhances the uniform load-bearing distribution of the overall structure and avoids the problem of unilateral overload. The tops of the four lifting gas rods 8 are in contact with the gas rod ball hinge cover 9 through the gas rod ball hinge joint 10. This connection method can achieve more flexible angle adjustment and achieve a stable connection with the seat bracket 7, ensuring that the cooperation between the various components during the seat adjustment process is smoother and more stable, and provides additional shock resistance and decompression effects, thereby improving sitting comfort.

[0039] Reference Figure 4 and Figure 5The top of the second metal part 2 of the chassis is fixedly connected with a second decorative cover 4 of the chassis, and the second decorative cover 4 of the chassis is used to decorate the second metal part 2 of the chassis. The main function of the second decorative cover 4 of the chassis is to provide the second metal part 2 of the chassis with a beautiful appearance, and also play a certain protective role to prevent the external environment from wearing or corroding the surface of the metal part. The installation of the second decorative cover 4 of the chassis ensures that the appearance of the chassis part is more concise and easy to clean, making the appearance of the entire office chair more tidy and in line with the aesthetic requirements of the modern office environment. The top of the first metal part 1 of the chassis is fixedly connected with a first decorative cover 3 of the chassis, and the first decorative cover 3 of the chassis is used to decorate the first metal part 1 of the chassis. The first decorative cover 3 of the chassis not only plays a role in improving the appearance, but also protects the first metal part 1 of the chassis from damage by external factors, and prevents dust, dirt and other pollutants from directly contacting the metal surface. Through the protection of the first decorative cover 3 of the chassis, the service life of the first metal part 1 of the chassis is extended, and at the same time, the aesthetics of the overall seat is improved. The bottom of the lifting gas rod 8 is fixedly connected The seat is lifted and lowered by the user, and the lifting and lowering of the seat is more stable, and the seat is stable and does not shake.

[0040] Specifically, during vertical lifting, the four lifting gas rods 8 are pressed down at the same time, which can evenly apply force to the seat support 7, thereby realizing vertical lifting of the seat support 7. This synchronous operation ensures the stability and stability of the seat support 7 during the lifting process, avoids tilting or uneven force, and makes the lifting of the seat smoother, adapting to the needs of different users.

[0041] When rocking left and right, the lifting gas rod 8 on one side is pressed down while the lifting gas rod 8 on the other side remains unchanged, thereby realizing the left and right rocking function of the seat. This design can flexibly adjust the rocking angle of the seat through the action of the gas rod on one side without changing the support on the other side, allowing users to enjoy moderate and comfortable rocking and providing a better dynamic sitting experience;

[0042] When rocking forward and backward, the front lifting gas rod 8 is retracted, while the rear lifting gas rod 8 remains unchanged. This operation enables the seat bracket 7 to rock smoothly forward and backward, avoiding unstable or uncomfortable rocking effects caused by uneven front and rear forces. Through this design, the seat can adapt to different sitting posture adjustment requirements while providing a comfortable rocking function;

[0043] When performing a single gas rod universal rocking, the seat bracket 7 rotates around its center point, causing one lifting gas rod 8 to retract, while the other three lifting gas rods 8 still support the seat bracket 7. This unique design allows the seat bracket 7 to rotate freely with its center point as the center of the circle, thereby achieving more flexible rocking and rotation functions, improving the adjustability and comfort of the seat, and meeting the needs of users in different work scenarios. This multifunctional, flexible and adjustable design further enhances the dynamic adaptability of the seat, allowing users to obtain higher comfort and convenience during the office process.

[0044] Working Principle: When using this new office chair chassis, the first metal part 1 of the chassis is connected to the bottom lifting cylinder. The outer wall of the first metal part 1 rotates the second metal part 2 of the chassis to provide a certain rotation angle. At the same time, the outer wall of the second metal part 2 of the chassis is supported by the lifting gas rod 8 and the seat bracket 7 in the front support arm 5 of the chassis. The two sides of the second metal part 2 of the chassis are supported by the lifting gas rod 8 and the seat bracket 7 in the rear support arm 6 of the chassis. The tops of the four lifting gas rods 8 are in contact with the gas rod ball hinge cover 9 through the gas rod ball hinge joint 10, and then connected to the seat bracket 7.

[0045] When vertically lifting, the four lifting gas rods 8 are pressed down at the same time, and the seat bracket 7 can be vertically lifted;

[0046] When shaking left and right, the lifting gas rod 8 on one side is pressed down, while the lifting gas rod 8 on the other side remains in the same position;

[0047] When rocking back and forth, the front lifting gas rod 8 is retracted, and the rear lifting gas rod 8 remains in position, thereby achieving rocking back and forth;

[0048] When the single gas rod is universally shaken, the seat bracket 7 rotates around the center of the seat bracket 7, causing one lifting gas rod 8 to retract, and the other three lifting gas rods 8 support the seat bracket 7, so that the seat bracket 7 can be rotated around the center point of the seat bracket 7.

[0049] 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 replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
