[0055] Please see Figure 1-6 The present invention provides a technical solution: a car seat cover with a bottom shielding structure, comprising a car seat 1, wherein the seat plate and the outer side of the backrest are both fitted with a cover body 2.

[0056] A ring-shaped shielding structure 5 is sewn at the lower edge of the outer side of the seat panel of the car seat 1, and its lower end rests against the floor of the car.

[0057] The back of the outer side of the backrest of the car seat 1 has a back cover structure 4 sewn onto the back of the outer side of the back cover body 2, and its lower end is attached to the back of the outer side of the seat panel of the car seat 1.

[0058] An adhesive gap plug 3 is fitted into the gap between the front wall of the outer backrest body 2 of the car seat 1 and the upper surface of the outer seat body 2 of the car seat 1.

[0059] Specifically in this embodiment, the car seat 1 is the prior art, including a seat plate and a backrest that are hinged to each other, and the hinge angle of the two can be adjusted. A protective body 2 is fitted on the outer wall of the seat plate and the backrest for protection.

[0060] Furthermore, a ring-shaped shielding structure 5 is used to cover the gap between the seat panel and the vehicle floor, preventing the gap, metal frame, slide rails, wiring harness, and the corresponding vehicle floor from being exposed; a back shielding structure 4 is used to cover the gap between the rear wall and backrest of the car seat 1; and an adhesive gap plug 3 is used to cover the gap between the front wall and backrest of the car seat 1, improving aesthetics and enhancing the sense of luxury in the vehicle's interior environment; it also prevents small items such as mobile phones, keys, and coins from entering the gaps, reducing the accumulation of dust and food crumbs and making cleaning easier.

[0061] More specifically, the ring-shaped shielding structure 5 uses a thicker nylon cloth as its main body, which falls onto the car floor by its own weight to shield the gap between the seat board and the car floor.

[0062] Understandably, the lower end of the annular shielding structure 5 is thickened or edged to further enhance its wear resistance.

[0063] In some embodiments, the annular shielding structure 5 includes:

[0064] The upper ring-shaped cover 51 is sewn at its upper end to the lower edge of the outer side of the cover body 2 of the car seat 1.

[0065] The lower annular cover 52 has a Velcro connection structure 53 installed between its upper end and the lower end of the upper annular cover 51.

[0066] The lower end of the lower ring-shaped cover 52 rests against the floor of the car body.

[0067] Specifically, in this embodiment, both the upper annular cover 51 and the lower annular cover 52 are made of thick nylon fabric. The upper annular cover 51 is sewn to the lower edge of the outer side of the cover body 2 of the car seat 1 as a fixing part. The lower annular cover 52 is connected to the lower end of the upper annular cover 51 through the Velcro connection structure 53, which can be easily disassembled when needed.

[0068] Furthermore, the lower circular cover 52 is close to the car floor, which is prone to contact with the car floor and the user's feet, and is easily stained with dirt, requiring disassembly for cleaning and maintenance.

[0069] In some embodiments, the Velcro connection structure 53 includes:

[0070] A strip-shaped connecting groove 531 is formed at the lower edge of the upper annular shielding cloth 51;

[0071] The lower annular shielding cloth 52 has a strip connecting cloth 532 sewn onto the upper end of the corresponding strip connecting groove 531;

[0072] A first Velcro closure 533 is fitted between the strip connecting fabric 532 and the inner wall of the strip connecting groove 531.

[0073] Specifically, in this embodiment, the first hook and loop fastener 533 adopts existing hook and loop fastener technology, including two parts: the hook side and the loop side.

[0074] Furthermore, the hook side of the hook and loop fastener is sewn onto the strip connecting fabric 532, and the loop side of the hook and loop fastener is sewn onto the inner wall of the strip connecting groove 531. The hook and loop fasteners adhere to each other to connect the upper annular covering fabric 51 and the lower annular covering fabric 52.

[0075] In some embodiments, a transverse connecting structure 54 is fitted between the lower end of the outer wall of the lower annular shielding cloth 52 and the upper surface of the vehicle compartment floor.

[0076] The lateral connection structure 54 includes:

[0077] A transverse shielding cloth 542, one end of which is sewn to the lower end of the outer wall of the lower annular shielding cloth 52;

[0078] The other end of the horizontal shielding cloth 542 is uniformly fixed with hooks 543 along its length.

[0079] A hook connecting block 541 is fixedly installed on the upper surface of the car body floor corresponding to hook 543;

[0080] Hook 543 is fitted onto the corresponding hook connecting block 541.

[0081] Specifically in this embodiment, the lower annular shielding cloth 52 remains in a natural hanging state due to its own weight. The lower end of the lower annular shielding cloth 52 is fixedly connected to the transverse shielding cloth 542, which is hung on the hook connecting block 541 fixed on the upper surface of the car floor through the hook 543 at the end. The end part of the hook 543 is inserted into the gap between the hook connecting block 541 and the upper surface of the car floor. There is a certain friction between the outer wall of the end of the hook 543 and the inner wall of the gap, so that a certain external force needs to be applied to overcome this friction when the hook 543 is removed, making the hook 543 more stable when suspended.

[0082] Furthermore, the hook 543 is suspended on the hook connecting block 541 on the upper surface of the car body floor, making the lower end of the lower annular cover 52 more stable in contact with the car body floor.

[0083] In some embodiments, the lower annular shielding cloth 52 is formed by a strip shielding cloth. When the strip shielding cloth is removed, it is removed starting from one end to release the Velcro connection structure 53. Compared with the overall annular removal method to release the Velcro connection structure 53, this method is more labor-saving and easier to clean and maintain.

[0084] Furthermore, the strip-shaped cover is easier to clean than the ring-shaped design after it is removed.

[0085] In some embodiments, a flexible tube 55 is sewn to the lower end of the lower annular shielding cloth 52 along the length direction, and a flexible rubber strip 56 is inserted inside it.

[0086] Specifically in this embodiment, the flexible tube 55 is made of thicker nylon cloth and is in contact with the ground for inserting the flexible rubber strip 56;

[0087] Furthermore, the flexible rubber strip 56 has a greater weight than the nylon fabric of the lower annular shielding cloth 52, which enhances the overall self-weight drooping effect of the lower annular shielding cloth 52.

[0088] In some embodiments, the back shielding structure 4 includes:

[0089] The back covering fabric 41 has a back wall with snap fasteners 43 evenly sewn through it;

[0090] The back of the outer side of the backrest of the car seat 1 is sewn with a snap fastener 42 corresponding to the snap fastener 43;

[0091] The female snap 43 is fastened into the corresponding female snap 42;

[0092] A magnetic connection structure 44 is fitted between the lower end of the back cover 41 and the back of the outer side of the seat panel of the car seat 1 and the back of the protective body 2.

[0093] The magnetic connection structure 44 includes:

[0094] The first magnetic block 442 is evenly pasted and embedded into the back of the protective body 2 on the outer side of the seat plate of the car seat 1.

[0095] The lower end of the back cover 41 has a second magnetic block 441 attached and embedded inside corresponding to the first magnetic block 442;

[0096] The first magnetic block 442 and the second magnetic block 441 are fixed by opposite magnetic adsorption.

[0097] Specifically in this embodiment, the back cover cloth 41 is fastened to the back of the outer back cover body 2 of the car seat 1 by the snap fastener 43 through its rear wall. There are multiple pairs of matching snap fasteners 43 and snap fasteners 42, which are combined to form a snap fastener, which is an application of the prior art.

[0098] Furthermore, the design of the back cover 41 enhances the protection of the back wall of the car seat 1. At the same time, the lower end of the back cover 41 extends to the back of the outer side of the seat panel of the car seat 1, covering the gap between the back wall of the car seat 1 and the seat panel.

[0099] More specifically, the lower end of the back cover 41 is magnetically attached to the first magnetic block 442 on the back of the outer side of the seat panel of the car seat 1 via the second magnetic block 441, so that the lower end of the back cover 41 is detachably connected to the back of the outer side of the seat panel of the car seat 1. This design ensures the coverage effect of the lower end of the back cover 41 on the gap between the back wall of the car seat 1 and the seat panel.

[0100] It is understandable that the adsorption positions of the first magnetic block 442 and the second magnetic block 441 can be staggered to ensure that the lower end of the back cover cloth 41 effectively covers the gap between the back wall and the seat board of the car seat 1.

[0101] In some embodiments, the adhesive gap plug 3 includes:

[0102] A cylindrical airbag 31 has an upper connecting strap 32 attached and fixed to its upper surface along its length.

[0103] A lower connecting strap 33 is attached and fixed to the lower surface of the cylindrical airbag 31 along its length.

[0104] A second Velcro strap 34 is fitted between the upper end of the outer wall of the upper connecting strap 32 and the lower end of the front wall of the outer side of the backrest of the car seat 1; the lower connecting strap 33 is arranged horizontally, and a third Velcro strap is fitted between its bottom surface and the upper surface of the outer side of the seat plate of the car seat 1.

[0105] Specifically, in this embodiment, the second hook and loop fastener 34 and the third hook and loop fastener have the same structure and adopt existing hook and loop fastener technology, including two parts: hook and loop fastener hook side and hook and loop fastener loop side.

[0106] Furthermore, the hook side of the second Velcro 34 is sewn onto the upper connecting strip 32, and the rough side is sewn onto the lower end of the front wall of the outer side of the backrest of the car seat 1. The upper connecting strip 32 is attached to the lower end of the front wall of the outer side of the backrest of the car seat 1 by attaching the rough side and the hook side of the Velcro.

[0107] The hook side of the third hook and loop fastener is sewn onto the lower connecting strip 33, and the rough side of the hook and loop fastener is sewn onto the upper surface of the outer side of the seat panel of the car seat 1. The lower connecting strip 33 is attached to the upper surface of the outer side of the seat panel of the car seat 1 by attaching the rough side and the hook side of the hook and loop fastener.

[0108] More specifically, the cylindrical airbag 31 is a flexible airbag with an outer wall wrapped in nylon cloth. The upper connecting strap 32 and the lower connecting strap 33 are both sewn onto this nylon cloth. After the upper connecting strap 32 and the lower connecting strap 33 are fixed in place, the position of the cylindrical airbag 31 covers the gap between the backrest and the seat of the car seat 1.

[0109] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the 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.
