[0001] The utility model relates to the technical field of threshold plates, in particular to an automobile plastic threshold plate. Background Art

[0002] Automobile plastic threshold plates are protective devices installed at the entrance of vehicle doors. They are usually located in the area where the door and the body of the vehicle come into contact, and are used to prevent wear and scratches when the door is in and out. Plastic threshold plates are made of high-strength plastic materials and have the characteristics of protecting the vehicle, preventing dust and dirt from accumulating, and improving the appearance of the vehicle. Metal plates and plastics can cause scratches or damage to plastic plates or metal plates, which makes the image unsightly.

[0003] For example, a plastic threshold plate for automobile disclosed in the patent publication number CN209921447U includes a threshold and a plurality of elastic buckles arranged at intervals formed on the lower surface of the threshold, the width of the protrusion in the middle of the elastic buckle in a natural state is greater than the width of the mounting hole, and an L-shaped reinforcing limiting plate structure is formed on one side of the elastic buckle, and the two sides of the reinforcing limiting plate structure protrude to one side to form a groove on one side of the reinforcing limiting plate structure. The plastic threshold plate for automobile is provided with a reinforcing limiting plate structure, so that after the threshold is installed on the sheet metal, together with the elastic buckle, the threshold can be stably installed.

[0004] Although the above device solves the problem of stable installation of the door sill, it still has certain defects: the door sill plates are all made of plastic plates, and metal plates are added on the top of some plastic plates. When in use, the door sill plates are often stepped on by people getting on the car, which can easily cause the plastic plates or metal plates to be scratched or damaged. This not only affects the appearance, but also causes damage to the door sill plates, which in turn requires replacement, causing inconvenience, and thirdly, it is inconvenient to replace. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a plastic door sill plate for an automobile, which prolongs the service life of the door sill and is convenient for replacement as a whole.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plastic automobile threshold plate, comprising a threshold plate body, a flexible pad connected to the top surface of the threshold plate body, the flexible pad is detachably connected to the threshold plate body, and a placement groove is opened in the threshold plate body, in which an airbag is placed.

[0007] Furthermore, the airbags are arranged in multiples and are equidistantly arranged in the placement groove, and the bottom is fixedly connected to the inner wall of the placement groove.

[0008] Furthermore, a partition bar is provided between two adjacent airbags, and the partition bar is fixedly connected to the bottom of the placement groove.

[0009] Furthermore, a lower embedded groove connected to the placement groove is also provided on the top surface of the threshold plate body, and two vertical bars and a horizontal bar are fixedly connected to the top surface of the lower embedded groove, and the two vertical bars and the horizontal bar are respectively located at the horizontal and vertical positions of the inner wall of the lower embedded groove. A frame is fixedly connected to the bottom of the flexible pad, and the inner wall of the frame abuts against the vertical bars and the horizontal bar, and the outer wall abuts against the inner wall of the lower embedded groove.

[0010] Furthermore, the two ends of the frame are protruding, and the top surface is clamped with a limiting piece, the two ends of the limiting piece are fixedly connected with an elastic clamping plate, and the top of the threshold plate body is provided with two limiting holes corresponding to the position of the elastic clamping plate.

[0011] Furthermore, a sanding cloth is fixedly connected to the outer surface of the flexible pad.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model provides a flexible pad, which can prevent metal plates or plastic plates from being scratched due to long-term trampling, and reduces wear and tear caused by direct trampling. The flexible pad is detachably connected to the threshold plate body, which can facilitate direct disassembly of the flexible pad, avoids direct replacement of the threshold plate body, and facilitates later cleaning and maintenance, reducing replacement costs. At the same time, when the flexible pad is subjected to the force of trampling, the flexible pad will first share the trampling force, and then the force will act on the airbag in the placement groove, which will buffer and offset part of the force, thereby achieving the effect of increasing the service life of the threshold plate body and avoiding the threshold plate body from being easily damaged and requiring overall replacement.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figures 1 to 5 As shown, a flexible pad 2 is connected to the top surface of the rocker plate body 1 , and the flexible pad 2 is detachably connected to the rocker plate body 1 . A placement groove 11 is provided in the rocker plate body 1 , and an airbag 10 is placed in the placement groove 11 .

[0022] like Figure 1 As shown, the automobile plastic threshold plate in the utility model is similar to the existing automobile plastic threshold plate structure, such as the patent with announcement number CN209921447U discloses an automobile plastic threshold plate. The main improvement of the utility model is that the threshold plate has a certain buffer force, such as Figures 1 to 5 As shown, when the automobile plastic threshold plate in the utility model is in use, when people step on the threshold plate body 1, they will first step on the large-area flexible pad 2. The flexible pad 2 can prevent people from scratching the metal plate or plastic plate due to long-term stepping. At the same time, the flexible pad 2 and the threshold plate body 1 are detachably connected, which can facilitate the disassembly of the flexible pad 2, facilitate subsequent cleaning, maintenance and replacement, and reduce the replacement cost; at the same time, when the flexible pad 2 is subjected to the force of stepping on, the flexible pad 2 will first share the stepping force, and then the force will act on the airbag 10 in the placement groove 11, and the airbag 10 will share the force, thereby achieving the effect of increasing the service life of the threshold plate body 2 and preventing the threshold plate body 1 from being easily damaged and requiring overall replacement.

[0023] like Figure 2 As shown, the airbags 10 are arranged in plurality and are equidistantly arranged in the placement groove 11 , and the bottom is fixedly connected to the inner wall of the placement groove 11 .

[0024] Specifically, in order to make people more stable when stepping, multiple airbags 10 are provided. When people step on the flexible pad 2, the airbags 10 will be squeezed to both sides due to pressure. Therefore, multiple airbags 10 will reduce the gas flow area and reduce the left and right squeezing of the airbags 10 after being stressed, thereby making people's stepping more stable.

[0025] like Figure 2 and Figure 4 As shown, a partition bar 4 is provided between two adjacent airbags 10 , and the partition bar 4 is fixedly connected to the bottom of the placement groove 11 .

[0026] Specifically, in order to make the airbag 10 more stable in the placement groove 11, the partition strip 4 is provided so that the force on the airbag 10 is more uniform and will not be squeezed to both sides, further ensuring the stability of people when stepping on it.

[0027] like Figure 2 , Figure 4 and Figure 5 As shown, the top surface of the threshold plate body 1 is also provided with a lower embedded groove 12 connected to the placement groove 11, and two vertical bars 5 and a horizontal bar 6 are fixedly connected to the top surface of the lower embedded groove 12, and the two vertical bars 5 and the horizontal bar 6 are respectively located at the horizontal and vertical positions of the inner wall of the lower embedded groove 12, and the bottom of the flexible pad 2 is fixedly connected with a frame 7, the inner wall of the frame 7 is against the vertical bars 5 and the horizontal bar 6, and the outer wall is against the inner wall of the lower embedded groove 12.

[0028] like Figure 5 As shown, the two ends of the frame 7 are protruding, and a limit plate 3 is clamped on the top surface. The two ends of the limit plate 3 are fixedly connected with an elastic clamping plate 9, and two limit holes 8 corresponding to the position of the elastic clamping plate 9 are opened on the top of the threshold plate body 1.

[0029] Specifically, when people connect the flexible pad 2 with the threshold plate body 1, they just need to clamp the frame 7 in the lower embedding groove 12 so that the frame 7 is restricted by the vertical bars 5 and the horizontal bars 6, and then restrict the limiting piece 3 and the two ends of the frame 7, and fix the limiting piece 3 on the threshold plate body 1 with an elastic card plate 9, so that the flexible pad 2 and the frame 7 can be installed and disassembled on the threshold plate body 1, which is convenient for cleaning the dust on the flexible pad 2 and replacing it after damage.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a sanding cloth is fixedly connected to the outer surface of the flexible pad 2. The arrangement of the sanding cloth can make more dust remain on the flexible pad 2 to prevent it from being brought into the vehicle, and the sanding cloth can be cleaned by disassembling the flexible pad 2.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
