Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, specifically a novel zero-gravity rotating structure for seats. Background Technology

[0002] As the automotive market increasingly demands comfort and versatility, high-end models have become bestsellers due to their common rail system and spacious interiors, achieving monthly sales of around 10,000 units. Each vehicle requires two seat-rotation components to meet potential user needs. Currently, car owners generally hope to use seat rotation to enable in-car entertainment, temporary rest, and other scenario-based functions, but existing technologies have significant shortcomings.

[0003] In existing technologies, the rotating seat function is typically achieved by directly adding a rotating disc to the bottom of the seat. While this solution meets basic rotation requirements, it increases the seat height by 10 centimeters, severely compromising the original ergonomic design. This results in poor leg support, reduced back support, and significantly decreased comfort, failing to meet the high-quality riding experience sought by users of high-altitude vehicles. Currently, the zero-gravity mechanism and rotating disc in existing seats are independent components. The layout of the zero-gravity mechanism does not consider the integration of the rotating function, requiring additional longitudinal space (i.e., the seat height) during installation. Directly stacking them inevitably increases the overall seat height, leading to comfort issues. This invention proposes a novel zero-gravity rotating seat structure that solves these problems. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a novel zero-gravity rotating seat structure, which solves the problems mentioned in the background section.

[0005] (II) Technical Solution To achieve the above objectives, this utility model is implemented through the following technical solution: a novel zero-gravity rotating structure for a seat, comprising a zero-gravity base frame, a seat frame, and an electric angle adjustment mechanism. A rotating disk is installed on the top of the zero-gravity base frame, and a base frame is rotatably connected to the top of the rotating disk. The electric angle adjustment mechanism includes a housing, a servo motor, a drive gear, a driven gear, a round rod, an upper rotating arm, a lower rotating arm, and a U-shaped plate. The output end of the servo motor is equipped with a drive gear that meshes with the driven gear. The outer surface of the round rod is fixedly connected to the driven gear and the lower rotating arm, respectively.

[0006] Optionally, the servo motor is installed inside the housing, and both the drive gear and the driven gear are located inside the housing. The housing is rotatably connected to the round rod via bearings, and the driven gear and the round rod are at the same center.

[0007] Optionally, one side of the upper rotating arm is rotatably connected to a round rod via a bearing, and the other side of the upper rotating arm is rotatably connected to the seat frame via a shaft. The side of the seat frame closest to the upper rotating arm is rotatably connected to the base frame via a shaft.

[0008] Optionally, the seat frame is positioned higher than the zero-gravity base frame, and both sides of the base frame are rotatably connected to the lower rotating arm via shafts. Mounting holes are provided on the outer side of the zero-gravity base frame.

[0009] Optionally, there are two upper rotating arms. One side of the U-shaped plate is fixedly connected to the outer shell, and the other side of the U-shaped plate is fixedly connected to one of the upper rotating arms.

[0010] Optionally, the end of the upper rotating arm furthest from the round rod is higher than the end of the lower rotating arm furthest from the round rod, and the position of the U-shaped plate is higher than the position of the lower rotating arm.

[0011] This utility model provides a novel zero-gravity rotating seat structure, which has the following beneficial effects: 1. This new zero-gravity rotating seat structure features an integrated design of the zero-gravity base frame and rotating disc. The installation position of the zero-gravity mechanism has been rearranged, eliminating redundant space from the original independent components. The zero-gravity and rotating functions are integrated into the seat frame, avoiding the problem of increasing the seat height by 10 centimeters. This ensures that the seat height conforms to the original vehicle's ergonomic design, maintaining the same riding comfort as the original vehicle. The overall seat structure is more compact and stable, avoiding abnormal noises or functional failures caused by loose independent components.

[0012] 2. This new zero-gravity rotating seat structure retains only the original car seat frame. Assembly is achieved by matching the mounting holes on the zero-gravity bottom frame with the mounting holes on the original car slide rails, without requiring large-scale modifications to the original car seat, resulting in high adaptability. It also combines zero-gravity and rotating functions to meet the needs of users for entertainment, temporary rest, and other scenarios, enhancing the multifunctionality of car seats.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example 1 Please see Figures 1 to 4 This utility model provides a technical solution: a novel zero-gravity rotating structure for a seat, including a zero-gravity base frame 1, a seat frame 2, and an electric angle adjustment mechanism 3. A rotating disk 4 is installed on the top of the zero-gravity base frame 1, and a base frame 5 is rotatably connected to the top of the rotating disk 4. The electric angle adjustment mechanism 3 includes a housing 301, a servo motor 302, a drive gear 303, a driven gear 304, a round rod 305, an upper rotating arm 306, a lower rotating arm 307, and a U-shaped plate 308. The output end of the servo motor 302 is equipped with a drive gear 303 that meshes with the driven gear 304. The outer surface of the round rod 305 is fixedly connected to the driven gear 304 and the lower rotating arm 307, respectively.

[0017] Specifically, the meshing of the driving gear 303 and the driven gear 304 facilitates the rotation of the driving gear 303 relative to the driven gear 304 during drive adjustment, and the driving gear 303 performs circular motion with the center of the driven gear 304 as the center.

[0018] Please refer to Figure 1 to Figure 4 The servo motor 302 is installed inside the housing 301. The driving gear 303 and the driven gear 304 are both located inside the housing 301. The housing 301 is rotatably connected to the round rod 305 through bearings. The driven gear 304 and the round rod 305 are at the same center.

[0019] Specifically, when the upper rotating arm 306 rotates relative to the lower rotating arm 307, it rotates around the center of the round rod 305, changing the angle between the upper rotating arm 306 and the lower rotating arm 307, which facilitates the height adjustment of the seat frame 2.

[0020] Please see Figures 1 to 4 One side of the upper rotating arm 306 is rotatably connected to the round rod 305 via a bearing, and the other side of the upper rotating arm 306 is rotatably connected to the seat frame 2 via a shaft. The side of the seat frame 2 closest to the upper rotating arm 306 is rotatably connected to the base frame 5 via a shaft.

[0021] Specifically, the mounting holes 6 on the zero-gravity base frame 1 are adapted to the original vehicle track, making it easy to install the zero-gravity base frame 1.

[0022] Please refer to Figure 1 to Figure 4 The seat frame 2 is positioned higher than the zero-gravity base frame 1. Both sides of the base frame 5 are rotatably connected to the lower rotating arm 307 via shafts. Mounting holes 6 are provided on the outer side of the zero-gravity base frame 1.

[0023] Specifically, the U-shaped plate 308 serves to connect the outer shell 301 and the upper rotating arm 306. When the outer shell 301 rotates relative to the round rod 305, it facilitates the rotation of the upper rotating arm 306, making it easy to adjust the angle between the upper rotating arm 306 and the lower rotating arm 307.

[0024] Please refer to Figure 1 to Figure 4 There are two upper rotating arms 306. One side of the U-shaped plate 308 is fixedly connected to the outer shell 301, and the other side of the U-shaped plate 308 is fixedly connected to one of the upper rotating arms 306.

[0025] Specifically, the upper rotating arm 306 is positioned higher than the lower rotating arm 307. When adjusting the angle between the upper rotating arm 306 and the lower rotating arm 307, the upper rotating arm 306 rotates relative to the lower rotating arm 307, facilitating the lifting and lowering adjustment of the seat frame 2.

[0026] Please refer to Figure 1 to Figure 4 The end of the upper rotating arm 306 that is away from the round rod 305 is higher than the end of the lower rotating arm 307 that is away from the round rod 305, and the position of the U-shaped plate 308 is higher than the position of the lower rotating arm 307.

[0027] In use, leveraging the core advantages of the Great Wall Wei brand mountain car's spacious interior and common rail design, and combining user needs in scenarios such as family travel, long-distance driving, and business reception, the system achieves synergistic application of zero gravity and rotation functions, covering diverse usage scenarios. The mounting holes 6 on the zero gravity base frame 1 are compatible with the original vehicle's sliding rails, facilitating connection. The integrated design of the zero gravity base frame 1 and the rotating disc 4 rearranges the installation position of the zero gravity mechanism, eliminating redundant space from the original independent components. This integrates the zero gravity and rotation functions within the seat frame, avoiding the issue of a 10cm increase in seat height and ensuring the seat height conforms to the original vehicle's ergonomic design, maintaining consistent riding comfort. The overall seat structure is more compact and stable, avoiding issues such as abnormal noises or functional failures caused by loose independent components. When adjusting to the appropriate height, the servo motor 302 drives the drive gear 303 to rotate, and the drive gear 303 meshes with the driven gear 304. The drive gear 303 rotates around the center of the driven gear 304 and the round rod 305, causing the housing 301 to drive the servo motor 302 and the drive gear 303 to rotate relative to the lower rotating arm 307, the round rod 305 and the driven gear 304. This causes the housing 301 to drive the U-shaped plate 308 and the upper rotating arm 306 to rotate around the round rod 305, thereby changing the angle between the upper rotating arm 306 and the lower rotating arm 307. The rotation of the upper rotating arm 306 provides an upward tilting force to the seat frame 2, causing the seat frame 2 to rotate around the rotational connection point between the seat frame 2 and the base frame 5. During the rotation of the seat frame 2, the distance between the center of the rotational connection point between the seat frame 2 and the base frame 5 and the round rod 305 changes, and the round rod 305 moves closer to the rotational connection point between the seat frame 2 and the base frame 5, facilitating the tilt and height adjustment of the seat frame 2. The rotating disk 4 facilitates the rotation of the seat frame 2 and improves its practicality.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
