Description

Technical Field

[0001] This utility model belongs to the technical field of automotive body interior parts, specifically, it relates to an upper guard plate for automotive B-pillars. Background Technology

[0002] The B-pillar, a key supporting structure on the side of a car body, typically has a protective plate, known as a B-pillar guard, installed on its outer side. This protects the B-pillar itself, enhances the vehicle's aesthetics, and provides a mounting base for interior components such as seat belts and coat hooks. Currently, B-pillar guards on the market still have several shortcomings in practical application: First, the shock absorption effect is poor. Due to the assembly gap between the B-pillar upper guard plate and the B-pillar body, they are prone to collision or friction during vehicle operation, producing abnormal noises and affecting the comfort of passengers. Second, the structural strength is insufficient. Traditional B-pillar upper guard plates mostly use a single flat structure or only have simple reinforcement structures, which are prone to deformation when subjected to external impacts (such as vibrations when closing doors or minor collisions), resulting in a short service life. Third, the ease and precision of installation are low. The existing guard plate fixing structure design is unreasonable, either requiring multiple bolts for fixing, making the installation process cumbersome, or lacking an effective positioning structure, causing the guard plate to shift after assembly, affecting the consistency of appearance. Fourth, the functional integration is poor. Most B-pillar upper guard plates only have decorative and protective functions and cannot provide a stable mounting base for components such as coat hooks and seat belts, requiring additional mounting structures on the B-pillar body, increasing the complexity of vehicle design and manufacturing costs.

[0003] In view of the shortcomings of the existing technology, there is an urgent need for a car B-pillar upper guard plate with good shock absorption, high structural strength, convenient installation and strong functional integration, so as to meet the design and use requirements of car body parts. Utility Model Content

[0004] In view of this, the technical problem to be solved by this utility model is to provide a car B-pillar upper guard plate, which avoids the problems of poor shock absorption, insufficient structural strength, low ease of installation and poor functional integration of previous car B-pillar upper guard plates.

[0005] To solve the above-mentioned technical problems, this utility model discloses a protective plate for the B-pillar of an automobile: The upper guard plate body has an outwardly flared upper side and inwardly flared flanges on both sides. A raised lining is located on the upper back of the upper guard plate body, with shock-absorbing bosses on both sides of the lining. A fixing seat is located on the lower back of the lining, with a recessed fixing seat, a through hole in the center, and guide posts on both sides, with buckle holes on the outer sides of the guide posts. Two buckle seats are located on the lower back of the upper guard plate body, and elastic buckles are installed therein. A seatbelt mounting hole is located in the center of the back of the upper guard plate body.

[0006] Preferably, the surface of the shock-absorbing boss is L-shaped and covered with shock-absorbing cotton.

[0007] Preferably, multiple reinforcing ribs are provided between the lining and the upper guard plate body.

[0008] Preferably, the upper guard plate body has a honeycomb-shaped reinforcing rib in the middle of its back side and multiple strip-shaped reinforcing ribs extending to the flanges on both sides.

[0009] Preferably, the fixing seat is recessed on the front of the upper guard plate body, and the snap-fit ​​hole is used to install the coat hook seat.

[0010] Preferably, positioning triangular blocks are also provided at the bottom of both sides of the back of the upper guard plate body.

[0011] Compared with the prior art, the present invention can achieve the following technical effects: Excellent shock absorption and noise reduction: By setting shock-absorbing bosses on both sides of the liner and covering the surface of the shock-absorbing bosses with L-shaped shock-absorbing cotton, the collision and friction between the guard plate and the B-pillar of the vehicle body can be effectively buffered, significantly reducing abnormal noises during vehicle operation and improving driving comfort.

[0012] High structural strength and strong resistance to deformation: Multiple reinforcing ribs between the lining and the upper guard plate body, honeycomb reinforcing ribs on the back of the upper guard plate body, and strip reinforcing ribs extending to the flange form a three-dimensional reinforcing structural network. While reducing the weight of the guard plate, it greatly improves the overall structural strength and resistance to deformation of the guard plate and extends the service life of the guard plate.

[0013] High functional integration: By setting seat belt mounting holes, a stable installation base is directly provided for seat belt mounting seats; the buckle holes on the outside of the fixing seat can be used to install coat and hat hook seats, realizing the integrated assembly of coat and hat hooks. There is no need to set an additional installation structure on the B-pillar of the vehicle body, which reduces the complexity of vehicle body design and manufacturing costs, and improves the functionality and practicality of the guard plate.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the above-mentioned technical effects at the same time. Attached Figure Description

Detailed Implementation

[0018] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0019] Please refer to Figures 1 to 3 , Figure 1 This is a front view of the B-pillar upper guard plate of an automobile according to an embodiment of this utility model; Figure 2 This is a rear view of the upper guard plate of the B-pillar of a car according to an embodiment of this utility model; Figure 3 yes Figure 2 A partial schematic diagram.

[0020] As shown in the figure, this embodiment provides an upper guard plate for a car B-pillar, including an upper guard plate body. The structural design of the upper guard plate body is adapted to the contour of the upper part of the car B-pillar, wherein: The upper side of the upper guard plate body 10 is curved outward to fit the outward curved contour of the upper part of the B-pillar, ensuring a smooth appearance. The left and right sides of the upper guard plate body 10 are provided with curved inward flanges 11, which can wrap around the side edge of the B-pillar, improve the protective effect, and enhance the fit between the guard plate and the B-pillar.

[0021] The upper back of the upper guard plate body 10 is provided with a raised lining edge 20, which extends along the length of the upper guard plate body 10. Its raised structure can increase the structural thickness of the upper side of the upper guard plate body 10 and improve local strength. The lining edge 20 is provided with shock-absorbing bosses 30 on both sides. The shock-absorbing bosses 30 are in direct contact with the B-pillar body of the vehicle body and are used to buffer the collision force between the guard plate and the B-pillar to reduce the generation of abnormal noise. The lower side of the lining edge 20 is provided with a fixing seat 40. The fixing seat 40 has a concave structure and a through hole 41 is opened in the middle of the fixing seat 40. The through hole 41 is used to pass through the fixing bolt or screw to realize the bolt fixation of the guard plate to the B-pillar. The fixing seat 40 is provided with guide posts 42 on both sides. The guide posts 42 can be inserted into the pre-set guide holes of the B-pillar during the assembly process to play a pre-positioning role. The outer side of the guide post is provided with a snap-fit ​​hole 43, which is used to cooperate with the snap-fit ​​structure to realize additional fixation or component installation.

[0022] In addition, two clip seats 50 are provided on the lower back side of the upper guard plate body 10. The two clip seats 50 are symmetrically distributed. The clip seats 50 are equipped with elastic clips. The elastic clips can be directly snapped into the pre-set snap holes in the B-pillar of the vehicle body without the need for additional tools, so as to achieve quick assembly of the guard plate.

[0023] A seat belt mounting hole 60 is provided in the middle of the back of the upper guard plate body 10. The size and shape of the seat belt mounting hole 60 are adapted to the structure of the seat belt mounting seat to fix the seat belt mounting seat and ensure that the seat belt is stable and reliable after assembly.

[0024] As a further optimization of this utility model, the surface of the shock-absorbing boss 30 is covered with shock-absorbing cotton in an L-shape. The shock-absorbing cotton is made of elastic materials (such as foamed rubber, sponge, etc.), and the L-shaped covering structure can completely cover the surface of the shock-absorbing boss 30 in contact with the B-pillar, further enhancing the shock absorption effect and avoiding abnormal noises caused by direct contact between metal and plastic.

[0025] In one embodiment of this utility model, multiple reinforcing ribs are provided between the lining 20 and the upper protective plate body 10. The reinforcing ribs are distributed at intervals along the length direction of the lining, and their two ends are fixedly connected to the bottom of the lining 20 and the back of the upper protective plate body 10, respectively, forming a triangular support structure, which effectively improves the structural strength of the connection between the lining 20 and the upper protective plate body 10 and prevents the lining 20 from breaking or deforming under stress.

[0026] Furthermore, a honeycomb-shaped reinforcing rib 71 is provided in the middle of the back of the upper guard plate body 10, and multiple strip-shaped reinforcing ribs 72 extending to the two side flanges 11 are provided. The honeycomb-shaped reinforcing ribs 71 are distributed radially around the seat belt mounting holes. Their honeycomb structure can significantly improve the deformation resistance of the middle area of ​​the upper guard plate body while reducing the overall weight of the guard plate. The strip-shaped reinforcing ribs 72 extend along the width direction of the upper guard plate body 10, with one end connected to the honeycomb-shaped reinforcing rib 71 and the other end extending to the inner side of the flange 11, transferring the strength of the middle area to the two side flanges, ensuring that the structural strength of the entire upper guard plate body 10 is uniform.

[0027] Furthermore, the mounting base 40 is recessed on the front of the upper guard plate body 10, and the snap-fit ​​hole 43 is used to install the coat hook seat. The recessed structure on the front avoids the protrusion of the mounting base from affecting the aesthetics of the front of the guard plate; the snap-fit ​​hole 43 is adapted to the snap-fit ​​structure of the coat hook seat, and the coat hook seat can be directly snapped into the snap-fit ​​hole to realize the integrated installation of the coat hook, without the need for additional installation brackets, thus simplifying the structural design.

[0028] As a further optimization of this utility model, positioning triangular blocks 80 are also provided on the bottom of both sides of the back of the upper guard plate body 10. The positioning triangular blocks 80 are right-angled triangles, with their right-angled sides fitting into the edge and back of the upper guard plate body, respectively. During assembly, the positioning triangular blocks contact the preset positioning surface of the B-pillar of the vehicle body, further ensuring the assembly position accuracy of the guard plate and preventing offset or tilting after assembly.

[0029] In summary, this utility model achieves excellent shock absorption and noise reduction through multi-structure collaboration, improves the overall structural strength and deformation resistance of the protective plate, simplifies the installation process and ensures assembly accuracy, and integrates seat belt and coat hook installation functions, reducing vehicle body design costs. It is suitable for the upper B-pillar protection and functional assembly of various passenger vehicles.
