Description

Technical Field

[0001] The invention relates to the technical field of automobile seats, and in particular to a flexible shielding structure of a seat floor lock and a layout method thereof. Background Art

[0002] In the prior art, the floor lock of the flip seat is buckled onto the ground wire in the use position by a lock tongue to lock the seat in the use position, and after the floor lock is unlocked, the seat flips over. When the seat flips to a predetermined angle, the internal structure of the lock is exposed.

[0003] In some other prior arts, in order to prevent the internal structure of the lock from being exposed, it is shielded by linking the ground lock and the plastic cover. When the ground lock is opened, the plastic cover is opened to shield, and when the ground lock is stored, the plastic cover is folded and flush with the seat cushion (see 202322309079.3); however, this structure often requires a larger space occupancy rate to meet the opening space of the plastic cover. If the vehicle body space cannot meet the opening space of the plastic parts, the internal structure of the lock in the known scheme cannot be effectively shielded. Summary of the invention

[0004] In order to solve the problems in the prior art that the lock cannot be shielded in a small layout space and the internal structure of the lock cannot be prevented from being exposed, the present invention aims to provide a flexible shielding structure for a seat floor lock with a simple structure and convenient layout, and a layout method thereof.

[0005] In order to achieve the above-mentioned purpose, the present invention proposes a flexible shielding structure for a seat floor lock, comprising a floor lock latch, a floor lock assembly, a floor lock cover assembly, a floor lock outer cover and a floor lock outer cover fixing bracket, wherein the floor lock outer cover fixing bracket is fixed to a seat frame, the floor lock assembly is hinged to the seat frame, the floor lock cover assembly is fixed to the front of the floor lock assembly, the floor lock outer cover covers the outer edge of the floor lock cover assembly and is fixed to the floor lock outer cover fixing bracket, the floor lock cover assembly comprises a floor lock cover body and a flexible cloth, one end of the flexible cloth is connected to the floor lock cover body by a first flexible cloth strip, and the other end is connected to the floor lock outer cover by a second flexible cloth strip, a shaping plate is fixed to the middle part of the flexible cloth, and when the floor lock assembly is flipped outward from a horizontal storage state to be locked with the floor lock latch, the flexible cloth can be folded between the floor lock cover body and the floor lock outer cover, and can be in a consistent outward flipping state driven by the shaping plate.

[0006] In the above scheme: the seat floor lock flexible shielding structure also includes a cable and a cable fixing bracket, the cable fixing bracket is fixed to the seat frame, the cable is fixed to the cable fixing bracket through a protective tube, and is connected to the floor lock assembly. Pulling the cable can unlock the floor lock assembly and can pull the floor lock assembly to flip over to a horizontal storage state.

[0007] In the above solution: the seat floor lock flexible shielding structure also includes a honeycomb panel, which covers the outer edge of the floor lock cover and is fixed to the seat frame. Its design purpose is to effectively eliminate the convex feeling of the floor lock cover, so that the bottom of the seat presents a smooth and flat surface, improving the overall aesthetics and practicality.

[0008] In the above scheme: the shaping plate is a PE sheet, which is sewn and connected to the flexible cloth, and its width is consistent with the width of the flexible cloth to ensure the shaping effect.

[0009] In the above scheme: the flexible cloth is a carpet cloth. When the floor lock assembly is in a horizontal storage state, the flexible cloth is laid flat between the floor lock cover body and the floor lock outer cover to cover the flip gap, so as to effectively ensure the consistency of the appearance.

[0010] In the above solution: the back side of the floor lock cover body is fixed to the floor lock assembly by screws, which is convenient for installation.

[0011] The present invention also proposes a method for arranging a flexible shielding structure of a seat floor lock, including a method for arranging a floor lock cover assembly, and the steps are as follows:

[0012] S1. Reversely design the installation position of the shaping board based on the state of the flexible cloth after assembly;

[0013] The flexible cloth is divided into two parts, front and back, with the folded edge formed by the flexible cloth being assembled and folded in the folded state as the dividing line. The part before the dividing line is the L3 section after removing the end interface section, and the part after the dividing line is the L2 section and the L1 section from front to back after removing the end interface section. The installation position of the shaping plate is the L2 section.

[0014] L1=2πT;

[0015] L2=L-(L3+L1);

[0016] T is the thickness of the flexible cloth; L is the total length of the flexible cloth excluding the interface sections at the front and rear ends.

[0017] S2, first sew the shaping plate onto the L2 segment of the flexible cloth, then sew and connect the front end of the flexible cloth to the front side of the first flexible cloth strip, and sew and connect the rear end of the flexible cloth to the front side of the second flexible cloth strip.

[0018] S3, firstly weld the back side of the second flexible cloth strip to the floor lock cover body by plastic heat fusion to form a floor lock cover assembly, and then assemble the floor lock cover assembly on the lock body.

[0019] S4. The back side of the first flexible cloth strip is connected to the outer cover of the floor lock by means of a buckle.

[0020] In the above solution: the length of the terminal connecting section is 5-6 mm, and the position of the terminal connecting section is the sewing position of the first flexible cloth strip or the second flexible cloth strip.

[0021] In the above scheme: L3≥3H1;

[0022] H1 is the thickness of the outer cover of the ground lock. This design ensures that when the flexible cloth is folded inward by external force, the shaping plate can be completely sunk into the flip gap to avoid the accumulation of flexible cloth, thereby ensuring that the ground lock assembly can be flipped to the normal opening angle.

[0023] In the above scheme: the floor lock assembly is hinged to the seat frame through two U-shaped brackets, the U-shaped bracket is welded to the seat frame, the floor lock assembly is rotatably connected to the U-shaped bracket, and a return spring is provided between the two; when the floor lock assembly is flipped to the open state, the uppermost end of the floor lock cover body can cover the lower edge of the rear end of the U-shaped bracket. That is, the length of the upper end of the floor lock cover body is greater than the height of the lower edge of the rear end of the U-shaped bracket, and the floor lock cover body plays an isolating role to prevent the flexible cloth from interfering with the U-shaped bracket after being folded inward by external force.

[0024] The beneficial effects of the present invention are:

[0025] 1. The flexible cloth is covered on the ground lock to avoid the exposure of the ground lock mechanism and ensure the consistency of appearance. 2. The shaping board has a supporting function, which can ensure the directional folding of the flexible cloth to avoid its concave and wrinkles, and also avoid the accumulation of cloth due to wrinkles when the lock body is in the open state and the folded flexible cloth interferes with the flipping angle of the lock body. Moreover, when the lock body is in the storage state, the shaping board can also play a role in supporting the flexible cloth to avoid the sinking of the flexible cloth in the middle. 3. The overall structure is simple, with few parts, and the use of flexible cloth is low in cost and light in weight, which has cost advantages. 4. The space occupancy rate is small, the installation is convenient, and the detachability is high. 5. The layout position of the shaping board is ingenious, which can not only ensure that the flexible cloth can be directionally turned outward without external force, but also ensure that the shaping board itself can be completely sunk into the turning gap when the flexible cloth is turned inward by external force to avoid interfering with the flipping angle of the lock body.
