Description

Technical Field

[0001] This utility model belongs to the field of automotive seats, specifically relating to an automotive seat vibration suppression structure. Background Technology

[0002] As users increasingly demand higher levels of automotive comfort, requirements such as lightweight seats have led to a lower seat modality. A lower seat modality is prone to coupling with suspension and powertrain modalities, causing noticeable vibrations, i.e., bumps and swaying, during vehicle operation, especially on uneven roads. This severely impacts the passenger experience. Furthermore, existing seats rely on front and rear landing gears for fixation and support; under impact, compression, or collision conditions, the seats are susceptible to deformation and breakage due to their low strength. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems by providing a vibration suppression structure for automobile seats. This vibration suppression structure adds side feet at the key stress points of the seat frame. The side feet improve the overall rigidity and strength of the seat, thereby increasing the resonance frequency of the seat and reducing the risk of damage to the vehicle during a collision.

[0004] To achieve the above objectives, this utility model provides a car seat vibration suppression structure, including a side foot. The side foot includes a connecting plate, and the two opposite sides of the connecting plate are downwardly bent side plates and downwardly bent foot bodies. The side foot is fixedly connected to the seat frame through a semi-enclosed assembly formed by the side plates, the connecting plate, and the upper part of the foot body. The foot body includes a support surface extending towards the vehicle body. The two lateral sides of the support surface have flanges that bend towards the side plates. The tops of the flanges on both sides are fixedly connected to the connecting plate. The lower part of the foot body bends away from the connecting plate, and a connecting hole is provided below the bend. The foot body has a downwardly recessed rib at the middle position along its length, which forms reinforcing ribs on both sides of the support surface.

[0005] As a further optimization, the two sides of the seat frame are side beams, and the main cross-section of the side beam is n-shaped, that is, the two sides of the main body have downward bending side flanges. The side feet are fixed to the middle of the side beams. A certain gap is left between the connecting plate and the main body. The side plate and the main body of the foot are fixed to the side flanges on both sides of the side beams.

[0006] As a further optimization, the connecting plate is equipped with positioning holes.

[0007] As a further optimization, the concave depth of the rib gradually increases from top to bottom.

[0008] As a further optimization, a gasket is provided at the connection hole, and the bolt passes through the connection hole and the gasket to connect to the vehicle body.

[0009] As a further optimization, the connection between the connecting plate and the downwardly bent side plate in the side foot, the connection between the connecting plate and the downwardly bent foot body, the connection between the supporting surface and the inwardly bent flanges on both sides in the foot body, the outward bending part at the bottom of the foot body, and the transition between the concave rib and the supporting surface are all rounded.

[0010] Advantages and beneficial effects of this utility model

[0011] 1. This utility model adds side feet at key stress points of the seat frame. In terms of strength, the side feet can distribute the load at these key stress points over a larger area and provide additional stress paths, resulting in a more uniform stress distribution and reducing the risk of damage. In terms of stiffness, supporting the side beams with the side feet reduces the deformation of the side beams, optimizes the force transmission path, and thus improves the seat's resistance to deformation and tilting. This, in turn, enhances the seat's stiffness and resonance frequency, suppressing seat vibration during vehicle operation.

[0012] 2. The side foot in this utility model is made of high-strength steel and is self-welded. The upper part of the side foot is a semi-enclosed assembly formed by a connecting plate, a side plate and the main body of the foot. The lower main section of the side foot is reinforced with an M-shape, thereby increasing the moment of inertia of the section, improving the strength and rigidity of the side foot, and enhancing the load-bearing capacity of the side foot.

Detailed Implementation

[0021] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figure 1 As shown, a car seat vibration suppression structure includes a side support foot 1, which is fixedly connected to a key stress point of the seat frame 2 to support the seat frame 2. In this embodiment, the key stress point of the seat is the middle of the side beam 21. Therefore, in this embodiment, the side support foot 1 is fixedly connected to the bottom end of the middle of the side beam 21. Figure 2 and Figure 3 As shown, the side anchor 1 includes a connecting plate 11. The left side of the connecting plate 11 is a downwardly bent side plate 12, and the right side is a downwardly bent anchor body 13. The upper parts of the side plate 12, connecting plate 11, and anchor body 13 form a semi-enclosed assembly, fixedly connected to the bottom of a side beam 21 with an n-shaped main cross-section. The side beam 21 includes a main body 211, with downwardly bent side flanges 212 on both sides. When the side anchor 1 is fixedly connected to the side beam 21, a certain gap is left between the connecting plate 11 and the main body 211. The side plate 12 is fixedly connected to the left side flange 212, and the upper part of the anchor body 13 is fixedly connected to the right side flange 212. This connection method, on the one hand, optimizes the force transmission path, avoiding direct connection between the anchor body 13 and the side flange 212, and allowing the force to be directly transmitted from the main body 211 and side flange 212 along the anchor body 13 (see...). Figure 5Instead, it is connected to the side beam 21 through a semi-enclosed assembly, allowing the force to be distributed to both sides along the main body 211. On one side, the force is transmitted to the base body 13 along the connecting plate 11 through the left side flange 212, and on the other side, the force is transmitted along the base body 13 through the right side flange 212, thus allowing the force to be transmitted evenly (see...). Figure 6 On the other hand, the semi-enclosed assembly can increase the moment of inertia of the section at the connection point between the side foot 1 and the side beam 21, thereby improving the strength and stiffness of the side foot 1.

[0023] like Figure 2 and Figure 3 As shown, the foot support body 13 includes an arc-shaped support surface 131 extending towards the vehicle body 3. The support surface 131 has flanges 132 bent towards the side plate 12 on both its front and rear sides. The tops of the flanges 132 on both sides are fixed to the connecting plate 11. The lower part of the foot support body 13 bends away from the connecting plate 11. A connecting hole 134 is provided below the bend of the foot support body 13. The side foot 1 is connected to the vehicle body 3 by inserting bolts 5 into the connecting hole 134, providing stable lateral support for the seat frame 2. The foot support body 13 has a downwardly recessed rib 133 at its midpoint along its length. The rib 133 gradually deepens from top to bottom, forming upwardly protruding reinforcing ribs 135 on both sides of the support surface 131. At this time, the main cross-section of the lower part of the footing body 13 is m-shaped. The m-shaped cross-section can increase the moment of inertia of the cross-section of the footing body 13, thereby improving the deformation resistance of the side footing 1 and thus improving the stiffness of the side footing.

[0024] As a further optimization, the connecting plate 11 is provided with positioning holes 111, which facilitates the welding and positioning of the side foot 1 and the side beam 21.

[0025] As a further optimization, a gasket 4 is provided at the connection hole 134. The gasket 4 can disperse stress, reduce stress per unit area, and thus improve strength.

[0026] As a further optimization, the following connections are made: between the main body 211 of the side beam 21 and the downward-bending side flanges 212 on both sides; between the connecting plate 11 and the downward-bending side plate 12 in the side anchor 1; between the connecting plate 11 and the downward-bending anchor body 13; between the supporting surface 131 and the inward-bending flanges 132 on both sides in the anchor body 13; and at the lower outward bend of the anchor body 13 and the transition between the concave rib 133 and the supporting surface 131. These rounded transitions reduce stress accumulation and improve the strength of the side beam 2 and the side anchor 1.

[0027] By adding side feet 1 at key stress points on the side beam 21 of the seat, the strength and rigidity of the seat can be improved. In terms of strength, the side feet 1 distribute the load at key stress points over a larger area and provide additional stress paths, resulting in more even stress distribution, thus reducing the risk of damage and improving safety. In terms of rigidity, the side feet 1 add extra support points to the side beam 21, reducing its deformation and optimizing the force transmission path, thereby improving the seat's resistance to deformation and tilting. This, in turn, enhances the seat's rigidity and resonant frequency. When the seat frequency is increased, it avoids common frequency ranges of external vibrations, reducing the probability of resonance, thus reducing resonant vibration, suppressing shaking effects, and decreasing the feeling of bumps or swaying, ultimately improving the riding experience.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the present utility model.
