Description

Technical Field

[0001] This invention relates to the field of vehicles, and more particularly to vehicle seats, especially zero-gravity vehicle seats. Background Technology

[0002] With the development of electric vehicles, more longitudinal space is needed inside the vehicle to accommodate larger battery packs. On the other hand, as occupants demand greater comfort, more and more vehicles, especially electric vehicles, are equipped with zero-gravity seats and seats with leg rests. However, for these seats, the additional functions and corresponding structural components will occupy the already very limited space between the seat plate and the vehicle floor, making it impossible to meet the need for longitudinal space inside the vehicle.

[0003] Due to the above circumstances, higher requirements are placed on vehicle seat suppliers, such as providing lower vehicle seat designs and thinner seat bases, while still ensuring the functionality of the vehicle seats.

[0004] Figure 1 This is a schematic diagram of a vehicle seat 1, an example of prior art. Figure 1 In this design, vehicle seat 1 is a zero-gravity vehicle seat, comprising a base 10 with a sliding rail structure, a seat frame 20 located above the base, a front link 30, a tilt adjustment link and a rear link 50, and a tilt adjustment drive mechanism 60 for adjusting the tilt angle of the seat frame 20. Furthermore, vehicle seat 1 also includes front and rear supports 70 mounted on the base 10, which are plate-shaped, with the front and rear links respectively connected to the front and rear supports 70.

[0005] The base 10 is fixed to the vehicle floor and is constructed, for example, as a slide rail, so that the seat frame 20 can slide along the slide rail via a front and rear drive mechanism (e.g., a drive motor, not shown) to achieve fore-and-aft adjustment of the vehicle seat. Utility Model Content

[0006] The purpose of this invention is to provide an improved vehicle seat that overcomes the aforementioned shortcomings of existing vehicle seats.

[0007] According to this utility model, a vehicle seat, particularly a zero-gravity vehicle seat, is provided, comprising a base and a seat frame, the seat frame being movably mounted on the base. According to an embodiment, the base is arranged in the lateral direction of the vehicle seat, preferably fixed to the vehicle's center console.

[0008] The concept of this invention is to use a base structure fixed to the vehicle's center console, rather than fixed to the vehicle floor, to achieve a "floating" vehicle seat structure. This arrangement reduces the space occupied between the seat frame and the vehicle floor, thus freeing up more space, for example, saving approximately 90-160mm of space under the seat.

[0009] According to an embodiment, in the lateral direction of the vehicle seat, the base is spaced a certain distance from the seat frame to allow for the installation of interior trim panels and other interior components.

[0010] According to an embodiment, the vehicle seat also includes a front synchronizer and a rear synchronizer, which extend through the seat frame at the front and rear of the vehicle frame, respectively. The two ends of the front synchronizer are fixed to the seat frame and pivotally connected to a base, respectively, while the two ends of the rear synchronizer are fixed to both the seat frame and the base, so as to synchronize the movement of both sides of the seat.

[0011] According to an embodiment, the front and rear synchronizer bars are tubular components. Preferably, to improve the installation strength of the vehicle seat, the walls of the front and rear synchronizer bars are relatively thick.

[0012] According to one embodiment, the vehicle seat also includes a tilt adjustment link. One end of the tilt adjustment link is pivotally connected to the front synchronizer bar, and the other end is pivotally connected to the base. This arrangement allows for adjustment of the vehicle seat's tilt angle.

[0013] According to an embodiment, the base is a slide rail structure, including a fixed part fixed to the vehicle's center console and a sliding part that can slide along the fixed part. Preferably, the vehicle seat also includes an adjustment drive mechanism for moving the sliding part relative to the fixed part, thereby moving the vehicle seat, which is arranged in the vehicle's center console. This arrangement enables adjustment of the vehicle seat's movement. The base can also be arranged in the vehicle's center console.

[0014] Preferably, the sliding part includes a front-to-back sliding part and a vertical sliding part. The front-to-back sliding part can slide along the fixed part in the front-to-back direction, and the vertical sliding part can slide along the fixed part in the vertical direction. Preferably, vertical sliding parts are provided at both the front and rear of the vehicle seat, and these parts can move up and down independently. With this arrangement, the fore-and-aft, height, and tilt adjustments of the vehicle seat can be realized, thereby integrating the seat adjustment function into a single component, eliminating the need for the previous linkage mechanism and corresponding separate adjustment drive mechanism.

[0015] Preferably, the vehicle seat has front and rear sliding parts that are controlled to move synchronously.

[0016] According to an embodiment, the vehicle seats are a driver's seat and / or a front passenger seat.

[0017] According to an embodiment, the vehicle seat also includes a leg rest assembly mounted on the seat frame and movable between an extended position and a retracted position, in the extended position being located in front of the seat frame and in the retracted position being located below the seat frame.

[0018] The vehicle seat of this invention has the following advantages: vehicle OEMs can achieve more flexible vehicle body layouts (especially for electric vehicles where the battery pack occupies a large amount of interior space), thereby effectively saving space; there is no need to set mounting points on the vehicle floor, and the brackets used to fix the vehicle frame and the linkages used to adjust the vehicle frame are eliminated; more legroom can be provided for rear passengers; more functional components can be arranged under the vehicle seat, and the adjustment range of the vehicle seat can be increased, thereby improving the comfort of the vehicle seat; the driver and front passenger seats can share the same drive structure; while maintaining the same number of functions, a higher degree of integration of mechanical components can be achieved, while maintaining manufacturing costs close to or lower than those of traditional layouts; since the adjustment drive mechanism is located in the lateral direction of the vehicle seat and can be fixed in the console, noise and vibration generated when adjusting the vehicle seat can be reduced; the vehicle seat structure is improved, reducing the weight of the first row of seats; a different visual experience is provided for vehicle occupants; the cost of vehicle seat components is reduced; no major modifications to the existing vehicle seat structure are required; length, height, and tilt adjustment functions are integrated into one component; the driver and front passenger seats or adjacent seats in the same row can share the mounting base and wiring harness channel.
