[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-2 , Figures 4-5A high-stability car door sill assembly includes a mounting bracket 1. A door sill plate 2 is mounted on the inner wall of the top of the mounting bracket 1. Several protruding strips 10 are fixedly connected to the rear side of the top of the door sill plate 2. A barbed hook and loop fastener 4 is fixedly connected to the front side of the top of the door sill plate 2. A brushed adhesive strip 3 is mounted on top of the barbed hook and loop fastener 4. A textured hook and loop fastener 3 is fixedly connected to the bottom of the brushed adhesive strip 3. Pressure bars 5 are fixedly connected to both the left and right sides of the bottom of the door sill plate 2. Screw holes 7 are provided on the opposite side of the pressure bars 5 at the bottom of the mounting bracket 1. Elastic plates 6 are fixedly connected to the bottom of the mounting bracket 1 on the lower side of the pressure rod 5. The bottom of the sill plate 2 is fixedly connected to the interlocking block 9 on the opposite side of the pressure rod 5. An arc-shaped cavity 18 is opened in the inner wall of the interlocking block 9. A stop block 19 is rotatably connected to the lower part of the opposite side of the inner wall of the arc-shaped cavity 18. The radius of curvature of the outer wall of the stop block 19 is the same as the radius of curvature of the inner wall of the arc-shaped cavity 18. A tension spring 20 is fixedly connected to the lower side of the inner wall of the stop block 19. The other end of the tension spring 20 is fixedly connected to the inner wall of the arc-shaped cavity 18.

[0026] The bottom inner wall of the mounting frame 1 is fixedly connected to the lower side of the fitting block 9 with a plug pin 8. The shape of the inner wall of the plug pin 8 matches the shape of the outer wall of the fitting block 9. A retaining groove 22 is opened at the opposite end of the plug pin 8. Irregular grooves 11 are opened on the left and right sides of the inner wall of the mounting frame 1. A lifting plate 17 is slidably connected to the inner wall of the mounting frame 1 on the opposite side of the irregular groove 11. The outer side of the lifting plate 17 is slidably connected to the inner wall of the retaining groove 22.

[0027] To further explain, firstly, the mounting bracket 1 is placed in the corresponding position on the car, the screws are aligned with the screw holes 7, and the screws are inserted and tightened to fix the mounting bracket 1. Then, the door sill plate 2 is aligned with the slot on the top of the mounting bracket 1 and inserted. During the insertion process, the interlocking block 9 will be precisely aligned with the opening on the top of the plug 8 and inserted. At this time, one side of the plug 8 will exert a force on the abutment block 19, causing the abutment block 19 to rotate and retract into the arc cavity 18. At the same time, the tension spring 20 is stretched. When the interlocking block 9 is fully inserted into the plug 8, the opening on one side of the arc cavity 18 will be aligned with the retaining groove 22. Under the elastic action of the tension spring 20, the abutment block 19 will rebound and rotate back to its original position and be inserted into the retaining groove 22, thereby realizing the limiting connection between the plug 8 and the interlocking block 9 and completing the installation of the door sill plate 2. After the installation is completed, the bottom of the pressure rod 5 will squeeze the elastic plate 6, causing the elastic plate 6 to generate elastic storage force.

[0028] When the car owner's shoes step on the door sill plate 2, the soles of the shoes will rub against the surface of the bristle sticker 3. With the help of this friction, the bristles on the surface of the bristle sticker 3 can clean the mud stains on the soles of the shoes, reducing the amount of mud stains brought into the car. Several raised strips 10 on the top of the door sill plate 2 can increase the friction between the soles of the shoes and the door sill plate 2, effectively preventing the soles of the shoes from slipping. If the bristle sticker 3 needs to be replaced later, the old bristle sticker 3 can be directly peeled off and replaced with the new bristle sticker 3.

[0029] Example 2

[0030] Please see Figures 2-3 Further, based on Embodiment 1, top blocks 21 are fixedly connected to opposite sides of the top of the lifting plate 17, rack 26 is fixedly connected to opposite ends of the lifting plate 17, rack 26 is slidably connected to the inner wall of the irregular groove 11 at both ends, push blocks 12 are slidably connected to the upper part of opposite sides of the inner wall of the irregular groove 11, springs 13 are fixedly connected to the bottom of push blocks 12, the other end of springs 13 is fixedly connected to the inner wall of the irregular groove 11, rack 14 is fixedly connected to opposite sides of the bottom of push blocks 12, gears 15 are provided between rack 14 and rack 26, gears 15 are rotatably connected to the inner wall of the irregular groove 11 at both ends, the opposite ends of the outer diameter of gears 15 are meshed with the opposite ends of rack 14, and the opposite ends of the outer diameter of gears 15 are meshed with the opposite ends of rack 26.

[0031] To further explain, to replace the sill plate 2, the push blocks 12 on both sides must be pressed simultaneously. The bottom of the push block 12 will squeeze the spring 13 and drive the rack 14 to slide down. Through the meshing transmission of the gear 15, the rack 2 16 that meshes with it will slide upward, thereby driving the lifting plate 17 to move upward. When the lifting plate 17 moves upward, the top block 21 at its top will push the abutment block 19 upward, causing the abutment block 19 to rotate again and retract into the arc cavity 18. When the lifting plate 17 moves upward to the top of the inner wall of the retaining groove 22, the abutment block 19 is completely retracted into the arc cavity 18, and the limiting connection between the plug 8 and the fitting block 9 is released. At this time, under the elastic storage force of the elastic plate 6, the pressure rod 5 is bounced upward, causing the sill plate 2 to detach from the inner wall of the mounting bracket 1. After removing the old sill plate 2, a new sill plate 2 of the same specification can be replaced.

[0032] Working principle: First, place the mounting bracket 1 in the corresponding position on the vehicle. Then, align the screw holes 7, insert the screws, and tighten them to secure the mounting bracket 1. Next, align the door sill plate 2 with the slot on the top of the mounting bracket 1 and insert it. During insertion, the fitting block 9 will align with the top opening of the plug 8 and insert itself. The plug 8 will exert force on the abutment block 19, causing it to rotate and retract into the arc-shaped cavity 18. Simultaneously, the tension spring 20 is stretched. After the fitting block 9 is fully inserted into the plug 8, one side of the arc-shaped cavity 18... The opening is aligned with the retaining groove 22. Then, under the elastic action of the tension spring 20, the abutment block 19 rebounds, rotates back to its original position, and snaps into the retaining groove 22. This achieves the limiting connection between the plug-in post 8 and the fitting block 9, and completes the installation of the sill plate 2. At this time, the bottom of the pressure rod 5 will squeeze the elastic sheet 6, causing the elastic sheet 6 to generate elastic force. When the sole of the car owner's shoe steps on the sill plate 2, it will generate a certain friction with the surface of the brush sticker 3. At the same time, relying on this friction, the bristles on the surface of the brush sticker 3 can clean the mud stains on the sole of the shoe, thereby reducing... To minimize mud entering the vehicle, the raised strips 10 on the top of the door sill plate 2 are designed to increase friction between the shoe sole and the top of the door sill plate 2, preventing slippage. When the brush pad 3 needs replacement, simply peel it off. To replace the door sill plate 2, simultaneously press the push blocks 12 on both sides, causing the bottom of the push spring 13 to compress and slide the rack 14 downwards. Then, under the meshing transmission of the gear 15, the meshing rack 2 16 slides upwards, causing the lifting plate 17 to move upwards. As the plate 17 moves upward, it will push the top block 21 upward to lift the abutment block 19, causing the abutment block 19 to rotate and retract into the arc cavity 18. After the lifting plate 17 moves to the top of the inner wall of the retaining groove 22, the abutment block 19 will be completely retracted into the arc cavity 18, thereby releasing the limiting connection between the plug-in pin 8 and the interlocking block 9. Then, under the elastic storage force of the elastic plate 6, the pressure rod 5 will spring upward and drive the sill plate 2 to detach from the inner wall of the mounting bracket 1. Then it can be removed and replaced with a brand new sill plate 2 of the same specification.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
