Description

Technical Field

[0001] This utility model relates to the field of seat frame structure technology, and in particular to a lightweight seat frame structure. Background Technology

[0002] Seats are an indispensable component in many fields, including automobiles, airplanes, trains, and office furniture. The weight of the seat frame has a significant impact on the energy consumption, performance, and transportation costs of the overall equipment.

[0003] Existing seat frames often suffer from bulky structures and inefficient material utilization, leading to unnecessary weight increases. This not only results in a larger overall seat weight but also increases transportation costs and energy consumption. Furthermore, it limits the functional expansion and design innovation of the seats to some extent. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the existing seat frame structure is bulky, resulting in a large overall weight of the seat, which increases transportation costs and energy consumption, and to a certain extent limits the expansion and innovation of seat functions. Therefore, a lightweight seat frame structure is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight seat frame structure, including a base frame, a support grid provided on the inner surface of the base frame, a set of weight reduction holes provided on the outer surface of the base frame, a set of transverse reinforcing rods fixedly installed on the inner surface of the base frame, a reinforcing plate fixedly installed between the inner surfaces of the set of transverse reinforcing rods, and two connecting plates fixedly installed on the top of the base frame.

[0006] Preferably, the outer walls of both connecting plates are provided with holes, and a connecting rod is movably inserted between the inner walls of the two holes.

[0007] Preferably, the outer wall of the connecting rod is fixedly fitted with two backrest frames, and the outer wall of each of the two backrest frames is provided with a set of weight reduction holes.

[0008] Preferably, two main support tubes are fixedly installed on opposite sides of the two backrest frames, and two longitudinal reinforcing rods are fixedly sleeved between the outer walls of the two main support tubes.

[0009] Preferably, a set of weight-reducing holes are provided on the outer wall of each of the two longitudinal reinforcing rods, and a set of auxiliary reinforcing tubes are fixedly installed on the opposite side of the two longitudinal reinforcing rods.

[0010] Preferably, an upper connecting pipe is fixedly installed between the tops of the two backrest frames, and two connecting rings are fixedly installed on the outer wall of the upper connecting pipe.

[0011] Preferably, a pillow frame is fixedly installed between the tops of the two connecting rings, and an armrest frame is fixedly installed on the outer wall of each of the two connecting plates.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, firstly, the supporting mesh can significantly improve the support stability of the bottom of the seat frame, while also reducing the weight. Secondly, the cooperation between the transverse reinforcing rod and the reinforcing plate can maintain the shape stability of the bottom frame of the seat, which can prevent the bottom of the seat from denting or being damaged due to excessive local pressure, thereby extending the service life of the seat. At the same time, the first, second and third weight-reducing holes reduce the weight by removing some materials while ensuring the overall strength and performance of the seat frame, thus reducing the weight of the seat while ensuring the strength of the seat.

[0014] 2. In this utility model, a stable frame structure is formed by the combined use of two main support tubes, two longitudinal reinforcing tubes, and auxiliary reinforcing tubes, which enhances the stability and strength of the backrest and can distribute the pressure of passengers leaning against the backrest more evenly.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1-3 As shown, this utility model provides a lightweight seat frame structure, including a base frame 1, a support grid 2 on the inner wall of the base frame 1, a set of weight-reducing holes 3 on the outer wall of the base frame 1, a set of transverse reinforcing rods 4 fixedly installed on the inner wall of the base frame 1, a reinforcing plate 5 fixedly installed between the inner walls of the set of transverse reinforcing rods 4, two connecting plates 6 fixedly installed on the top of the base frame 1, holes 7 on the outer walls of the two connecting plates 6, a connecting rod 8 movably inserted between the inner walls of the two holes 7, two backrest frames 9 fixedly fitted on the outer walls of the connecting rods 8, and a set of weight-reducing holes 10 on the outer walls of the two backrest frames 9.

[0024] The overall effect of Embodiment 1 is as follows: First, the support grid 2 at the bottom of the base frame 1 is a lighter design compared with the traditional solid bottom support structure. While ensuring sufficient support strength, it reduces the amount of material used. At the same time, a set of transverse reinforcing rods 4 and reinforcing plates 5 can share some of the vertical pressure and distribute the pressure more evenly to the entire bottom frame structure of the seat. This can prevent the bottom of the seat from denting or being damaged due to excessive local pressure, thereby extending the service life of the seat. Second, the weight reduction holes 1 3 and 2 10 reduce the weight of the seat frame and can also reduce transportation costs during transportation.

[0025] Example 2, as Figures 1-4 As shown, two main support tubes 11 are fixedly installed on opposite sides of the two backrest frames 9. Two longitudinal reinforcing rods 12 are fixedly sleeved between the outer walls of the two main support tubes 11. A set of weight-reducing holes 13 are opened on the outer walls of the two longitudinal reinforcing rods 12. A set of auxiliary reinforcing tubes 14 are fixedly installed on opposite sides of the two longitudinal reinforcing rods 12. An upper connecting tube 15 is fixedly installed between the tops of the two backrest frames 9. Two connecting rings 16 are fixedly installed on the outer walls of the upper connecting tube 15. A pillow frame 17 is fixedly installed between the tops of the two connecting rings 16. Armrest frames 18 are fixedly installed on the outer walls of the two connecting plates 6.

[0026] The overall effect of Embodiment 2 is that, during normal use, the two main support tubes 11 are fixedly connected to the two backrest frames 9 at both ends, thereby enhancing the connection strength between the two backrest frames 9. At the same time, the longitudinal reinforcing rods 12 are sleeved between the outer walls of the two main support tubes 11, and a set of auxiliary reinforcing tubes 14 are installed between the two longitudinal reinforcing rods 12. This allows for a more reasonable distribution of stress on the backrest frames 9. When subjected to external forces, the stress can be more evenly distributed on the reinforcing rods and the surrounding frame material, thereby avoiding structural failure caused by excessive local stress. This helps to improve the durability and fatigue resistance of the seat frame, enhances the support of the backrest, and allows passengers to experience more stable and comfortable support when sitting.

[0027] Working Principle: Firstly, during normal use, the outer wall of the base frame 1 has a set of weight-reduction holes 1-3, the outer walls of both backrest frames 9 have a set of weight-reduction holes 2-10, and the outer walls of both longitudinal reinforcing rods 12 have a set of weight-reduction holes 3-13. Weight-reduction holes 1-3, 2-10, and 3-13 ensure that the seat frame maintains sufficient strength and rigidity while reducing weight, optimizing the stress state of the seat frame, improving its resistance to deformation and fatigue, and also improving the heat dissipation performance of the seat frame. Air can flow more smoothly through the seat frame, thus accelerating heat dissipation. Secondly, the inner wall of the base frame 1 is provided with a support grid 2. The addition of the support grid 2 optimizes the weight distribution of the seat frame, allowing the seat frame to maintain sufficient strength while minimizing weight. Simultaneously, the support grid 2 also improves the ventilation and breathability of the seat. Due to the grid structure, air can flow more smoothly. The bottom of the seat accelerates heat dissipation and moisture removal. Secondly, the horizontal reinforcing rod 4 is connected to the reinforcing plate 5, which increases the strength of the base frame 1. At the same time, the reinforcing plate 5 is located in the middle, which makes the force on the seat more even. The base frame 1 is fixedly connected to two connecting plates 6, and the two backrest frames 9 are fitted on the outer wall of the connecting rod 8, so that the backrest frames 9 are connected to the base frame 1. The two backrest frames 9 are connected by two main support tubes 11. The main support tubes 11 can be made of high-strength aluminum alloy. High-strength aluminum alloy has a relatively low density, but its strength performance is excellent. It can effectively reduce the overall weight of the seat frame while ensuring the strength of the frame. It can effectively resist deformation and provide reliable support for passengers. At the same time, the two longitudinal reinforcing rods 12 and a set of auxiliary reinforcing tubes 14 further enhance the connection strength and effectively improve the overall stability of the backrest. The headrest frame 17 is connected to the upper connecting tube 15 through two connecting rings 16, which facilitates the subsequent installation of the headrest.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
