Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, specifically a lightweight magnesium alloy seat frame. Background Technology

[0002] The seat frame is the core support structure of a seat, typically made of metal, plastic, or composite materials. It bears the weight of the seat and provides sufficient strength and stability to ensure the safety and comfort of the seat. In the case of a car seat, the frame needs to support the weight of the passengers inside the vehicle while also possessing sufficient strength to protect them during a collision. The design of the seat frame takes into account impact absorption, adjustability, and seat comfort.

[0003] The existing technology has the following shortcomings: Application number 202020199098.9 proposes a lightweight magnesium alloy seat frame, which includes a seat cushion frame and a backrest frame. The seat cushion frame and the backrest frame are hinged together. A headrest frame is connected to the upper end of the backrest frame. The headrest frame includes a crossbar and two parallel square rods, square rod one and square rod two. The two ends of the crossbar are fixedly connected to square rod one and square rod two. A motor is fixedly connected to the end face of square rod one away from square rod two. A fixed rod is fixedly connected to the output shaft of the motor. A cam one and a cam two are connected to the fixed rod. Cam one is located at the end of the fixed rod away from the motor. Cam one and cam two are in the same direction and parallel to each other. The output shaft of the motor is rotatably connected to square rod two. When the driver is driving or resting, the output shaft of the motor drives the fixed rod to rotate, which in turn drives cam one and cam two to rotate. The rotation of cam one and cam two can provide a cyclical massage effect on the driver's neck, reducing driver fatigue.

[0004] The elastic components in the seat chassis of the aforementioned equipment were not shown. Currently, the conventional method is to use spring components. However, when the seat has been used for a long time or is damaged internally, it is inconvenient to replace. The entire seat needs to be disassembled before it can be replaced, which is time-consuming and laborious. At the same time, the lumbar support plate and springs are used to support the user's waist. The lumbar support plate is directly connected to the middle of the backrest frame by the springs and does not protrude from the backrest frame. When under pressure, it will only sink in and fail to support the waist, thus affecting the comfort of the seat. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a lightweight magnesium alloy seat frame to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight magnesium alloy seat frame, including a backrest frame and a seat chassis, wherein a connecting component is provided between the backrest frame and the seat chassis, an elastic structure is provided on the seat chassis, a support mechanism is provided inside the backrest frame, a limiting hole is provided on the inner side of the seat chassis, a through hole is provided at one end of the seat chassis, a threaded hole is provided at one end of the seat chassis near the through hole, symmetrical storage holes are provided on the inner side of the backrest frame, and extension ends are provided at both ends of the support mechanism;

[0010] As a preferred technical solution of this utility model: the fixing plate is fixedly installed on the top of the protruding section, and the bolt passes through the fixing plate.

[0011] As a preferred technical solution of this utility model: one end of the rigid plug-in end of the chassis elastic structure is inserted into the corresponding limiting hole after passing through the through hole, the protruding section extends out of the seat chassis, and the bolt passes through the fixing plate and is threadedly connected to the threaded hole.

[0014] Compared with the prior art, this utility model provides a lightweight magnesium alloy seat frame, which has the following beneficial effects:

[0015] 1.

[0016] 2. This lightweight magnesium alloy seat frame, by setting a support mechanism, storage holes, and extension ends, has an arc-shaped support mechanism that can support the waist. When the pressure of the waist is applied to the support mechanism, depending on the magnitude of the force, the extension ends of the soft steel support mechanism will extend into the storage holes under the action of its own flexibility, and always keep the support mechanism close to the waist, effectively supporting the waist and ensuring seat comfort.

A connecting component 3 is provided between the backrest frame 1 and the seat chassis 2. An elastic structure 4 is provided on the seat chassis 2. A support mechanism 5 is provided inside the backrest frame 1. A limiting hole 6 is provided on the inner side of the seat chassis 2. A through hole 7 is provided at one end of the seat chassis 2. A threaded hole 8 is provided at one end of the seat chassis 2 and near the through hole 7. A storage hole 9 is symmetrically provided on the inner side of the backrest frame 1. An extension end 10 is provided at both ends of the support mechanism 5.

[0024] The perforation 7 facilitates the insertion of the chassis elastic structure 4, and the limiting hole 6 restricts the position of one end of the chassis elastic structure 4 in the seat chassis 2.

[0025] The chassis elastic structure 4 is specifically composed of an elastic section 401, a rigid plug end 402, an extension section 403, a fixing plate 404, and bolts 405. The extension section 403 is provided with a fixing plate 404, and the fixing plate 404 is provided with bolts 405.

[0026] The protruding section 403 allows for easy extraction of the chassis elastic structure 4, facilitating operation. The bolts 405 ensure the stability of the chassis elastic structure 4 after it is installed on the seat chassis 2.

[0027] In this embodiment, there are two sets of connecting components 3, which are distributed on both sides of the backrest frame 1. One end of the connecting component 3 is rotatably connected to the backrest frame 1, and the other end of the connecting component 3 is rotatably connected to the seat chassis 2. The rigid insertion end 402 is welded to one end of the elastic section 401, and the extension section 403 is welded to the other end of the elastic section 401. The rigid insertion end 402 and the extension section 403 are both made of alloy steel, and the elastic section 401 is made of mild steel. There are six sets of chassis elastic structure 4.

[0028] Specifically, the connecting component 3 facilitates the connection between the backrest frame 1 and the seat chassis 2, the elastic section 401 provides sufficient elasticity to the seat chassis 2, and the rigid insertion end 402 ensures the stability of one end of the chassis elastic structure 4 within the limiting hole 6.

[0029] In this embodiment, the fixing plate 404 is fixedly installed on the top of the protruding section 403, the bolt 405 passes through the fixing plate 404, one end of the rigid plug end 402 in the chassis elastic structure 4 passes through the through hole 7 and is inserted into the corresponding limiting hole 6, the protruding section 403 extends out of the seat chassis 2, and the bolt 405 passes through the fixing plate 404 and is threadedly connected to the threaded hole 8.

[0030] Specifically, the fixing plate 404 facilitates the installation of bolts 405, and the threaded hole 8 can be connected with bolts 405 to ensure the installation effect of the chassis elastic structure 4.

[0031] In this embodiment, the extension end 10 and the support mechanism 5 are integrally formed. The extension ends 10 at both ends of the support mechanism 5 are inserted into the storage holes 9. There are five sets of support mechanisms 5. The support mechanism 5 and the extension end 10 are both made of soft steel. The backrest frame 1 and the seat chassis 2 are both made of magnesium alloy.

[0032] Specifically, the support mechanism 5 can support the user's lower back, providing a comfortable seating experience.

[0033] The working principle and usage process of this utility model are as follows: After the backrest frame 1 is connected to the seat chassis 2 via the connecting component 3, a sponge portion can be added to the frame to complete the production of the entire seat. If the seat loses its elasticity due to damage to the chassis elastic structure 4 on the seat chassis 2 caused by increased use, the bolt 405 can be unscrewed from the back of the seat, disengaging the bolt 405 from the threaded hole 8. Then, the extension section 403 can be pulled outwards, and the elastic section 401 will be pulled out of the seat chassis 2 through the through hole 7. The damaged chassis elastic structure 4 can then be directly extracted and replaced. When installing the new chassis elastic structure 4, the rigid insertion end 402 is passed through the through hole 7 and inserted into the limiting hole 6. Then, the bolt 405 is passed through and tightened in the threaded hole 8, completing the chassis installation. The replacement of the elastic structure 4 allows for convenient replacement of the chassis elastic structure 4 in the seat chassis 2 without disassembling the entire seat, saving time and effort. When the user sits on the seat, the lumbar region is supported by the arc-shaped support mechanism 5. When the pressure on the lumbar region is applied to the support mechanism 5, depending on the magnitude of the force, the extension ends 10 of the soft steel support mechanism 5 will extend into the storage holes 9 under its own flexible characteristics, and always keep the support mechanism 5 close to the lumbar region, effectively supporting the lumbar region and ensuring seat comfort. Since the backrest frame 1 and the seat chassis 2 are made of magnesium alloy, the lightweight structure of magnesium alloy can achieve the effect of lightweighting the overall seat frame compared to conventional seats, while ensuring the strength of the overall structure.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
