Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology and relates to a snap-fit ​​structure that facilitates the installation of seat feet. Background Technology

[0002] Currently, with the rapid development of the automotive industry, especially the passenger vehicle sector, the comfort and appearance of car seats have become key highlights for customers. However, while satisfying aesthetics and comfort, the ease of assembly and use of the seats must also be considered. Seats are generally assembled to the vehicle floor via feet on the frame. Meanwhile, to enhance the seat's appearance, the feet are usually decorated with covers, which adds extra workload to seat installation. Currently, the commonly used foot covers are split-type, requiring OEMs to open the covers and then bolt the entire seat to the vehicle body. However, opening the foot covers requires additional tools and time, and during this process, it can cause scratches on the plastic surface and also impact production speed. Therefore, this innovative example aims to improve the ease of seat installation. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a snap-fit ​​structure that facilitates the installation of seat feet. This snap-fit ​​structure enables quick and non-destructive installation, improving assembly efficiency.

[0004] According to the technical solution of this utility model: a buckle structure for easy installation of seat feet, including a foot cover body and a foot cover flip cover, characterized in that: guide connecting plates are respectively provided on both sides of the bottom surface of the foot cover flip cover along its width direction. Each of the guide connecting plates is provided with a first clip and a second clip at intervals along the vertical direction; The inner wall of the foot cover body is provided with locking points that cooperate with the first clip and the second clip; The locking point and the first clamp are respectively provided with mutually cooperating guide slopes; The guide connecting plate is a plate-shaped structure capable of elastic deformation; By cooperating with the guide slope of the first clip and the guide slope of the locking point, during assembly, the guide connecting plate is squeezed inward and elastically retracts by the locking point, so that the first clip can slide to the bottom of the locking point via the guide slope of the locking point, and the locking point is engaged between the first clip and the second clip. At this time, the foot cover flip cover is in the pre-locked position and can move up and down relative to the foot cover body; When the foot cover flip-up moves downwards until the second clip engages with the bottom surface of the locking point, the foot cover flip-up is in the final locked position.

[0005] As a further improvement of this utility model, the width of the connection between the upper end of the guide connecting plate and the foot cover flip cover is smaller than the width of its lower part.

[0006] As a further improvement of this utility model, the guide connecting plate is provided with an inward protrusion in its narrow upper region.

[0007] As a further improvement of this utility model, the bottom surface of the top plate of the foot cover body is provided with a downwardly extending limiting reinforcing rib.

[0008] As a further improvement of this utility model, the foot cover body is provided with a positioning protrusion on the inner wall of the outer protective plate on the side where the limiting reinforcing rib is provided.

[0009] As a further improvement of this utility model, when the pre-locking position is reached, an operating gap suitable for hand operation is formed between the foot cover flip cover and the foot cover body.

[0010] As a further improvement of this utility model, in the pre-locked position, the locking force between the first clip and the locking point is less than the locking force between the second clip and the locking point in the final locked position.

[0011] As a further improvement of this utility model, the buckle structure is applied to the foot of a car seat, the foot cover body is fixed to the seat frame, and the foot cover flip-up is used to cover the foot bolt installation area.

[0012] The technical advantages of this utility model are as follows: The structure is reasonable and ingenious. By setting up double clips and locking points, it achieves both pre-locking and final locking states for the foot cover flip-top, facilitating quick opening of the flip-top by vehicle manufacturers when installing bolts, eliminating the need for tools and preventing scratches. The special structural design of the guide connecting plate effectively prevents shrinkage marks on plastic parts, improving the product's appearance quality. The setting of limiting reinforcing ribs and positioning protrusions enhances the overall structural rigidity and positioning accuracy. The structure is simple and reliable, easy to assemble, and suitable for the batch installation needs of automotive seat feet. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the pre-locking structure of this utility model.

[0014] Figure 2 This is a schematic diagram of the final locking position of this utility model. Detailed Implementation

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0016] 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.

[0017] Figure 1 , 2 The components include the base cover body 1, locking point 1-1, limiting reinforcing rib 1-2, base cover flip cover 2, guide connecting plate 2-1, protrusion 2-11, first clip 2-21, second clip 2-22, etc.

[0018] like Figure 1 , 2 As shown, this utility model provides a snap-on structure that facilitates the installation of seat feet, aiming to solve the problems of inconvenient installation, easy scratching of the surface, and impact on production cycle of existing foot covers.

[0019] like Figure 1 , 2 As shown, the snap-fit ​​structure for facilitating seat foot installation of this utility model includes a foot cover body 1 and a foot cover flip cover 2. The foot cover flip cover 2 is made entirely of plastic, and guide connecting plates 2-1 are integrally formed on both sides of its bottom surface along the width direction.

[0020] Each guide connecting plate 2-1 is provided with a first clip 2-21 and a second clip 2-22 spaced apart along the vertical direction. Correspondingly, locking points 1-1 that cooperate with these clips are provided on the inner wall of the foot cover body 1.

[0021] To ensure smooth assembly, both locking point 1-1 and the first clip 2-21 are machined with mutually cooperating guide slopes. Crucially, the guide connecting plate 2-1 itself is constructed as a plate-like structure capable of elastic deformation. During the assembly of the foot cover flip 2 to the foot cover body 1, the guide slope of the first clip 2-21 contacts the guide slope of locking point 1-1. As the foot cover flip 2 is pressed down, locking point 1-1 presses against the first clip 2-21, forcing the entire guide connecting plate 2-1 to elastically retract inward. This allows the first clip 2-21 to slide past locking point 1-1 and move beneath it. When the assembly force is removed, the guide connecting plate 2-1 recovers elastically, ensuring that locking point 1-1 is stably engaged between the first clip 2-21 and the second clip 2-22.

[0022] At this time, the foot cover flip cover 2 is in the pre-locked position. In this position, the foot cover flip cover 2 can move up and down relative to the foot cover body 1, and the distance it moves is the distance between the first clip 2-21 and the second clip 2-22. At the same time, a clear operating gap is formed between the foot cover flip cover 2 and the foot cover body 1. The width of this gap is designed to allow the operator's fingers to insert, so that the flip cover can be opened manually without tools.

[0023] When final locking is required, press down on the foot cover flip 2. The guide connecting plate 2-1 will elastically deform again, causing the second clip 2-22 to pass over the locking point 1-1. When the second clip 2-22 is fully engaged with the bottom surface of the locking point 1-1, the foot cover flip 2 reaches the final locked position. In this position, the foot cover flip 2 and the foot cover body 1 are tightly fitted together and can no longer move relative to each other, ensuring the stability of the structure and the flatness of the appearance.

[0024] As an important improvement of this utility model, the width of the connection between the upper end of the guide connecting plate 2-1 and the main body of the foot cover flip cover 2 is intentionally designed to be smaller than the width of its lower part. This variable width design effectively avoids shrinkage marks caused by uneven wall thickness during injection molding of plastic parts, thus improving the appearance quality of the product; on the other hand, the narrower root enhances the elasticity of the guide connecting plate 2-1, making it easier for it to undergo the required elastic deformation during the snap-fit ​​process.

[0025] To further enhance the structural strength of the guide connecting plate 2-1 at its narrow root and prevent it from breaking after repeated stress, an inward protrusion 2-11 is provided in the narrower area at the top of the guide connecting plate 2-1. This protrusion 2-11 acts as a local reinforcing rib.

[0026] Regarding the footrest cover body 1, a downwardly extending limiting reinforcing rib 1-2 is provided on the bottom surface of its top plate. This limiting reinforcing rib 1-2 not only improves the overall rigidity of the footrest cover body 1 and prevents it from deforming under pressure, but also plays an internal limiting role when the footrest cover flap 2 is closed. In addition, a positioning protrusion (not separately labeled in the figure) is provided on the inner wall of the outer protective plate 1-3 on the side where the limiting reinforcing rib 1-2 is provided. This positioning protrusion helps to quickly and accurately position the footrest cover body 1 when it is installed on the seat frame 3.

[0027] In the mechanical design of this structure, the locking force between the first clip 2-21 and the locking point 1-1 during pre-locking is designed to be less than the locking force between the second clip 2-22 and the locking point 1-1 during final locking. The pre-locking locking force is sufficient to ensure that the foot cover flip cover 2 will not accidentally come loose during vehicle transportation, while also facilitating manual opening by the operator. The greater locking force during final locking ensures the reliability and sealing of the product in use.

[0028] The snap-fit ​​structure of this utility model is specifically designed for car seat feet. The foot cover body 1 is fixed to the seat frame through the mounting structure (such as slots or screw holes) on it, while the foot cover flip cover 2 is used to cover the bolt mounting area connecting the foot to the car body, which not only serves a decorative purpose but also provides a convenient installation and maintenance passage.

[0029] The working principle and assembly process of this utility model are briefly described below: Chair assembly: On the chair assembly line, the foot cover flip cover 2 is pressed onto the foot cover body 1 until it reaches the pre-locked position. At this time, the foot cover flip cover 2 remains open but is reliably locked.

[0030] Transportation: The complete chair with the pre-locking foot cover flip cover 2 is transported to the main plant. Vibration during transportation will not cause the flip cover to close accidentally or fall off.

[0031] OEM installation: Operators can directly pry open the pre-locked foot cover flip cover 2 by hand without any tools, exposing the foot bolt holes for tightening operations, effectively avoiding tool scratches on the surface of plastic parts and significantly improving assembly speed.

[0032] Final locking: After tightening the bolts, press the foot cover 2 down to the final locking position to complete the installation. The appearance is neat and beautiful.

[0033] 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.
