The B-pillar is mainly used to support the roof and the front and rear doors. When the vehicle is hit from the side, the B-pillar can also protect the occupants. The B-pillar is equipped with a protective plate for the exterior.

[0003] The patent publication number "CN211543694U" discloses a car B-pillar guard plate, which includes a body, a first reinforcing rib, a second reinforcing rib, and a top-pressing device. The body has a U-shaped cross-section. A connecting plate is fixedly installed at the bottom of the body. The first reinforcing rib is fixedly installed on the upper part of the body, and the second reinforcing rib is fixedly installed on the lower part of the body. The first and second reinforcing ribs fit together with the surface of the body. Several support plates are provided on both sides of the body, and two first-pressing devices are provided on the upper part of the body.

[0004] As shown in the above technology, existing automotive B-pillar guards are installed using a clip-on method. However, the degree of tightness after installation is limited, which may cause loosening and abnormal noises when the car is driving. Moreover, the clip-on method may break during disassembly and installation. Utility Model Content

An adjusting bolt is threadedly connected to the inner surface of the fixed base, and a moving block is sleeved on the surface of the adjusting bolt. A buckle is fixedly connected to one side of the moving block.

[0008] Preferably, a limiting spring is sleeved on the surface of the adjusting bolt located between the moving block and the end of the adjusting bolt. The rotation of the adjusting bolt shortens the distance between its end and the moving block, thereby shortening the stroke of the limiting spring.

[0009] Preferably, the multi-layer composite structure of the main body of the protective plate consists of an impact-resistant layer, a buffer layer, and an energy-absorbing layer from the inside out, and each layer is bonded together with a fixing bolt and adhesive.

[0010] Preferably, the impact-resistant layer is made of high-strength steel, the buffer layer is made of aluminum alloy and the buffer layer is honeycomb in shape, and the energy-absorbing layer is made of engineering plastic.

[0011] Preferably, the cross-section of the main body of the guard plate is U-shaped, and multiple reinforcing ribs are provided along the bend of the U-shape, with the multiple reinforcing ribs arranged at equal intervals from top to bottom.

[0012] Preferably, the front of the guard plate body is provided with a through groove, and the through groove is used for the installation of the safety belt structure.

[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] Please see Figures 1-4 This high-strength automotive B-pillar protection plate offers two technical solutions:

[0025] The first embodiment includes a guard plate body 1, the cross section of the guard plate body 1 is U-shaped, and multiple reinforcing ribs 3 are provided along the U-shaped bend. The multiple reinforcing ribs 3 are arranged at equal intervals from top to bottom. A through groove 2 is provided on the front of the guard plate body 1, and the through groove 2 is used for the installation of the safety belt structure. The guard plate body 1 adopts a multi-layer composite structure to increase the overall bending resistance. Several adjustable buckle components 4 are provided on the edges of the rear opening of the guard plate body 1.

[0026] The adjustable buckle assembly 4 includes a fixed base 41, which is fixedly connected to the inner side of the guard plate body 1. An adjusting bolt 42 is threadedly connected to the inner surface of the fixed base 41. A moving block 43 is sleeved on the surface of the adjusting bolt 42. A buckle 44 is fixedly connected to one side of the moving block 43. A limiting spring 45 is sleeved on the surface of the adjusting bolt 42 located between the moving block 43 and the end of the adjusting bolt 42. The adjustment bolt 42 rotates to shorten the distance between its end and the moving block 43, thereby shortening the stroke of the limiting spring 45.

[0027] When the main body of the guard plate 1 is installed via the adjustable buckle assembly 4, the buckle 44 has better mobility during installation and is less likely to break. Furthermore, by rotating the adjusting bolt 42 to shorten the spring stroke, the tightness of the buckle 44 can be adjusted, thus improving the practicality of the device during use.

[0028] The multi-layer composite structure of the main body 1 of the protective plate consists of an impact-resistant layer 11, a buffer layer 12 and an energy-absorbing layer 13 from the inside out. Each layer is bonded together with adhesive by fixing bolts 14. The impact-resistant layer 11 is made of high-strength steel, the buffer layer 12 is made of aluminum alloy and has a honeycomb shape, and the energy-absorbing layer 13 is made of engineering plastic.

[0029] The main body of the protective plate 1 adopts a multi-layer composite structure, consisting of an impact-resistant layer 11, a buffer layer 12, and an energy-absorbing layer 13 from the outside to the inside, which improves the overall bending strength.

[0030] In use, align the main body 1 of the guard plate with the installation part and press it in. When pressing in, the buckle 44 is squeezed and moves. After passing the installation position, it returns to its original position under the action of the limit spring 45, thus completing the clamping operation. In addition, if the clamping degree is insufficient, rotate the adjusting bolt 42 to shorten the distance between the end of the adjusting bolt 42 and the moving block 43, thereby increasing the compression degree of the limit spring 45 and improving the clamping degree.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0032] 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.
