Description

Technical Field

[0001] This utility model belongs to the field of automotive seat equipment technology, and relates to a rotating shielding structure for seat bottom protection plate. Background Technology

[0002] With the upgrading of the automotive consumer market, users have placed higher demands on the visual aesthetics and overall feel of interior design. Car seats, especially second-row seats, often have a forward-folding function to facilitate passenger access to the third row. However, during the forward-folding process, the underlying structure (such as the metal frame and adjustment mechanism) is inevitably exposed, severely affecting the refinement and overall aesthetics of the interior, and reducing the user experience.

[0003] Currently, some high-end models are trying to solve this problem by adding an extra electric cover or a complex linkage mechanism, but this has led to problems such as significantly increased costs, structural complexity, decreased reliability, and the occupation of more valuable space.

[0004] Therefore, there is an urgent need in this field for a solution that is simple in structure, low in cost, requires no additional control, and can reliably and automatically shield the internal structure when the seat is tilted forward. Summary of the Invention

[0005] To address the aforementioned problems, this utility model provides a rotating shielding structure for a seat bottom panel, which automatically shields exposed internal parts when the seat is folded forward, improving the aesthetics of the interior. It also has the advantages of simple structure, low cost, and high reliability.

[0006] According to the technical solution of this utility model: a rotating shielding structure for a seat bottom panel, characterized in that it includes: Underbody protection plate, fixedly installed at the bottom of the car seat; The flip-top cover is rotatably connected to the bottom protective plate via a pivot. An elastic element is connected between the flip cover and the bottom guard plate to provide a reset torque for the flip cover. The bracket cover, fixed to the vehicle body or seat frame, interferes with the movement path of the flip-up cover; When the seat folds forward, the interference between the flip cover and the bracket cover decreases, and the flip cover is reset and pressed tightly against the bottom guard plate under the action of the elastic element to cover the internal structure of the seat; when the seat is reset backward, the interference between the flip cover and the bracket cover increases, and the flip cover is lifted by the bracket cover and flips over against the torque of the elastic element.

[0007] As a further improvement of this utility model, the elastic element is a torsion spring, with its spring coil sleeved on the rotating shaft, one end acting on the bottom guard plate and the other end acting on the flip cover plate.

[0008] As a further improvement of this utility model, the flip cover is configured such that when the seat is in the normal sitting position, it is lifted up by the bracket cover, so that the flip cover and the bottom guard plate form an angle.

[0009] As a further improvement of this utility model, the contact surface between the flip cover and the bracket cover is an inclined surface or a curved surface, so as to achieve smooth lifting and resetting actions during the interference process.

[0010] The technical advantages of this utility model are as follows: The product has a reasonable and ingenious structure, effectively concealing the exposed internal parts when the seat is folded forward, keeping the seat bottom flat and aesthetically pleasing, thus enhancing the overall refinement and technological feel of the vehicle interior. Utilizing the seat's forward folding motion as a power source, the cover automatically opens and closes through mechanical interference and spring reset, requiring no circuitry, sensors, or drivers. The structure is simple, reliable, and durable. The compact structure with few parts, using mature springs and plastic components, results in low production costs and minimal additional space occupation within the seat. Whether open or closed, the cover is pressed firmly against the mating parts (bottom plate or bracket cover) by the pre-tightening force of the elastic element, effectively preventing vibrations and noises that may occur during vehicle operation.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] Figure 1-6 The components include a flip cover 1, a bottom guard plate 2, an elastic element 3, and a bracket cover 4.

[0020] like Figure 1-6 As shown, the rotating shielding structure for a seat bottom panel provided by this utility model mainly consists of a flip cover 1, a bottom panel 2, an elastic element 3, and a bracket cover 4.

[0021] The bottom guard plate 2 is typically made of plastic and is fixed to the bottom of the seat frame by clips or screws. The flip cover 1 is rotatably mounted on the bottom guard plate 2 via a pivot (not shown separately in the figure). The elastic element 3 is preferably a torsion spring, with its coil sleeved on the pivot, one end fixed to the bottom guard plate 2, and the other end acting on the flip cover 1, providing the flip cover 1 with a torque that always tends to close (i.e., conform to the bottom guard plate 2).

[0022] The bracket cover 4 is fixedly mounted on the vehicle floor or a fixed frame that does not rotate with the seat. Its installation position is precisely calculated so that when the seat is in position... Figure 1 In the normal seating position shown, the upper edge of the support cover 4 pushes up the flip cover 1, allowing it to overcome the force of the torsion spring and maintain an open angle. When the seat is folded forward... Figure 4 When the seat moves, the flip cover 1 and the bracket cover 4 are disengaged or the interference is minimal. At this time, under the action of the reset torque of the torsion spring 3, the flip cover 1 quickly rotates and closes, tightly covering the bottom guard plate 2.

[0023] To ensure smooth operation, the contact area between the flip cover 1 and the bracket cover 4 can be designed as a guide slope or a smooth curved surface.

[0024] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
