Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and more specifically, to a B-pillar exterior trim assembly structure. Background Technology

[0002] Currently, the B-pillar exterior trim is part of the car's interior, mainly installed on the front and rear door frames, serving to decorate the interior space.

[0003] Chinese patent discloses a B-pillar exterior trim panel assembly structure (authorization announcement number CN213323353U). This patented technology can solve the shortcomings of traditional B-pillar exterior trim panels, which are made of sheet metal. Sheet metal parts have long development cycles, are difficult to control in terms of size, have high mold development costs, and are heavy. However, the fixing structure during installation is simple. In actual use, only the top and bottom of the trim panel can be locked and fixed, resulting in the central position of the trim panel being loose. When the vehicle is in motion, the airflow will put pressure on the trim panel, causing the central position of the trim panel to vibrate. During the vibration, the trim panel will generate a lot of noise and increase the wind resistance of the vehicle, resulting in increased fuel consumption. At the same time, the vibration of the trim panel due to airflow will accelerate its damage and reduce its lifespan. How to invent a B-pillar exterior trim panel assembly structure to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a B-pillar exterior trim panel assembly structure, which aims to improve the problem of the exterior trim panel shaking due to airflow during use caused by the single fixing structure during installation.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a B-pillar exterior trim panel assembly structure, including a trim panel mechanism and a reinforcement mechanism assembled on the back of the trim panel mechanism. The trim panel mechanism includes a trim panel body, with mounting plates fixedly installed at the top and bottom of the trim panel body. Mounting sleeves are fixedly installed at the top and bottom of the back of the trim panel body. Mounting screws are threaded into the interior of both sets of mounting sleeves. Multiple sets of stainless steel springs are fixedly installed at equal intervals inside the trim panel body. A waterproof rubber strip is provided on the outer side of the back of the trim panel body.

[0007] The reinforcement mechanism includes a mounting tube installed on the back of the main body of the decorative panel, a telescopic tube slidably installed inside the mounting tube, a locking plate fixedly installed on the back of the telescopic tube, and a reset tension spring connected to the mounting tube fixedly installed inside the telescopic tube.

[0008] Preferably, mounting grooves are provided at the top and bottom of the back of the main body of the decorative panel, a top plate is slidably installed inside the mounting groove, two sets of support springs fixedly installed inside the mounting groove and fixedly connected to the top plate, and an anti-slip groove is provided on the back of the top plate.

[0009] By adopting the above technical solution, the top plate is slidably installed inside the mounting groove, and the support spring installed inside the mounting groove can provide elastic support for the top plate. The support spring and the top plate can support the upper and lower half of the main body of the trim panel during installation and use, ensuring the flatness of the surface of the main body of the trim panel when it is installed on the outer wall of the B-pillar, avoiding the situation where local grooves of the main body of the trim panel affect the overall aesthetics, and ensuring the stability of the exterior trim panel when decorating the B-pillar of the vehicle.

[0010] Preferably, a mounting rod is fixedly installed on the front of the waterproof strip, and an assembly groove for use with the mounting rod is provided on the back of the decorative panel body.

[0011] By adopting the above technical solution, the mounting rod is installed in the assembly slot by snap-fit. Therefore, the waterproof strip can be installed and fixed by the mounting rod and the assembly slot, and the mounting rod and the assembly slot facilitate the subsequent disassembly and replacement of the waterproof strip by the staff.

[0012] Preferably, the top and bottom of the outer wall of the telescopic tube are provided with limiting grooves, and the top and bottom of the inner wall of the mounting tube are fixedly installed with limiting rods that cooperate with the limiting grooves.

[0013] By adopting the above technical solution, the limiting rod is slidably installed inside the limiting groove. The limiting rod and the limiting groove can limit the angle of the telescopic tube and the locking plate when they extend and retract, thus preventing the locking plate from rotating and falling out of the B-pillar locking hole.

[0014] Preferably, multiple sets of sealing rods are fixedly installed on the front of both sets of mounting plates.

[0015] By adopting the above technical solution, the sealing rod increases the sealing performance and stability when the mounting plate is connected to the B-pillar slot, avoiding vibration when the mounting plate is connected to the slot.

[0016] Preferably, two sets of positioning plates are fixedly installed on the upper and lower sides of the back of the main body of the decorative panel.

[0017] By adopting the above technical solution, the positioning plate is installed in the pre-set positioning groove of the B-pillar. The positioning plate and the positioning groove cooperate to position the back of the main body of the trim panel, thereby greatly increasing the stability of the main body of the trim panel when it is installed on the outer wall of the B-pillar and avoiding displacement.

[0018] The beneficial effects of this utility model are as follows: the cooperation between the trim panel body, the mounting sleeve, and the mounting screw allows the trim panel body to cover and decorate the B-pillar of the vehicle, enhancing the overall aesthetics of the vehicle. The mounting sleeve and mounting screw can fix the top of the trim panel body to the top, increasing the convenience of installation. With the help of the mounting tube and locking plate, the central position of the trim panel body can be connected and fixed to the B-pillar of the vehicle, achieving multi-point fixation of the trim panel body. This prevents the trim panel body from shaking due to airflow in the central position during vehicle operation, ensuring the stability of the exterior trim panel during use and extending its service life.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example, refer to Figure 1-7 A B-pillar exterior trim panel assembly structure includes a trim panel mechanism 1 and a reinforcing mechanism 2 assembled on the back of the trim panel mechanism 1. The trim panel mechanism 1 includes a trim panel body 101. Mounting plates 102 are fixedly installed on the top and bottom of the trim panel body 101. Mounting sleeves 104 are fixedly installed on the upper and lower sides of the back of the trim panel body 101. Mounting screws 105 are threaded into the interior of both sets of mounting sleeves 104. Multiple sets of stainless steel springs 109 are fixedly installed at equal intervals inside the trim panel body 101. A waterproof rubber strip 4 is provided on the outer side of the back of the trim panel body 101. The reinforcing mechanism 2 includes a mounting tube 202 installed on the back of the trim panel body 101. A telescopic tube 203 is slidably installed inside the mounting tube 202. A locking plate 201 is fixedly installed on the back of the telescopic tube 203. A reset spring 206 connected to the mounting tube 202 is fixedly installed inside the telescopic tube 203.

[0030] The trim panel body 101 is attached to the outer wall of the vehicle's B-pillar. Mounting plates 102 installed at the top and bottom of the trim panel body 101 are inserted into pre-set slots in the vehicle's B-pillar, thus connecting the top of the trim panel body 101 to the vehicle's B-pillar. However, a large gap may appear between the top and bottom of the trim panel body 101 when it is used to decorate the surface of the vehicle's B-pillar. Furthermore, two sets of mounting sleeves 104 installed on the back of the trim panel body 101 are inserted into pre-drilled mounting holes in the outer wall of the vehicle's B-pillar. Mounting screws 105 are threaded through the mounting sleeves 104 on the back of the vehicle's B-pillar. This allows for the installation and fixation of the trim panel body 101. Before installation, the trim panel body 101 is placed horizontally and perpendicularly attached to the B-pillar of the vehicle. A locking plate 201 is movably installed at the center of the back of the trim panel body 101 via the mounting tube 202 and the telescopic tube 203. A return spring 206 installed inside the telescopic tube 203 can elastically pull the locking plate 201, thus allowing the locking plate 201 to be elastically installed via the telescopic tube 203 and the return spring 206, and the locking plate 201 is locked at the center of the back of the trim panel body 101. The locking plate 201 is inserted into a pre-drilled locking hole in the B-pillar, and the pre-drilled locking hole matches the size of the locking plate 201 when it is placed horizontally. By rotating the main body 101 of the trim panel, the locking plate 201 can be misaligned with the locking hole on the B-pillar, thus achieving installation and locking at the central position of the trim panel 101 during installation. The two sets of mounting sleeves 104 and the locking plate 201 allow the trim panel 101 to be installed on the outer wall of the vehicle's B-pillar using a three-point fixing method, significantly increasing the stability of the exterior trim panel when installed on the outside of the vehicle's B-pillar. Stability is ensured by preventing the exterior trim panel from shaking due to airflow during vehicle operation, thus guaranteeing its service life. The stainless steel spring 109 increases the toughness of the trim panel body 101, preventing localized dents and deformations during prolonged use, thus ensuring the aesthetics of the exterior trim panel over long-term use. Furthermore, the waterproof rubber strip 4 enhances the sealing of the trim panel body 101 when installed on the B-pillar exterior wall, preventing rainwater from seeping into the vehicle interior through the connection between the trim panel body 101 and the B-pillar, thus ensuring the stability of the exterior trim panel during use.

[0031] Furthermore, mounting grooves 107 are provided on the upper and lower sides of the back of the main body 101 of the decorative panel. The top plate 3 is slidably installed inside the mounting groove 107. Two sets of support springs 302 are fixedly installed inside the mounting groove 107 and fixedly connected to the top plate 3. The back of the top plate 3 is provided with anti-slip grooves 301.

[0032] It should be noted that the top plate 3 is slidably installed inside the mounting groove 107, and the support spring 302 installed inside the mounting groove 107 can provide elastic support for the top plate 3. The support spring 302 and the top plate 3 can support the upper and lower half of the trim panel body 101 during installation and use, ensuring the flatness of the surface of the trim panel body 101 when it is installed on the outer wall of the B-pillar, avoiding the situation where local grooves of the trim panel body 101 affect the overall aesthetics, and ensuring the stability of the exterior trim panel when decorating the B-pillar of the vehicle.

[0033] Furthermore, a mounting rod 401 is fixedly installed on the front of the waterproof strip 4, and an assembly groove 108 is provided on the back of the decorative panel body 101 to cooperate with the mounting rod 401.

[0034] It should be noted that the mounting rod 401 is installed in the assembly groove 108 by snap-fitting. Therefore, the waterproof strip 4 can be installed and fixed by the mounting rod 401 and the assembly groove 108, and the mounting rod 401 and the assembly groove 108 facilitate the subsequent disassembly and replacement of the waterproof strip 4 by the staff.

[0035] Furthermore, limiting grooves 204 are provided at the top and bottom of the outer wall of the telescopic tube 203, and limiting rods 205 that cooperate with the limiting grooves 204 are fixedly installed at the top and bottom of the inner wall of the mounting tube 202.

[0036] It should be noted that the limiting rod 205 is slidably installed inside the limiting groove 204. The limiting rod 205 and the limiting groove 204 can limit the angle of the telescopic tube 203 and the locking plate 201 when they extend and retract, thus preventing the locking plate 201 from rotating and falling out of the locking hole of the B-pillar.

[0037] Furthermore, multiple sets of sealing rods 103 are fixedly installed on the front of both sets of mounting plates 102;

[0038] It should be noted that the sealing rod 103 increases the sealing and stability when the mounting plate 102 is connected to the B-pillar slot, and avoids vibration when the mounting plate 102 is connected to the slot.

[0039] Furthermore, two sets of positioning plates 106 are fixedly installed on the upper and lower sides of the back of the main body of the decorative panel 101;

[0040] It should be noted that the positioning plate 106 is installed in the pre-set positioning groove of the B-pillar. The positioning plate 106 and the positioning groove can be used to position the back of the main body of the trim panel 101, thereby greatly increasing the stability of the main body of the trim panel 101 when it is installed on the outer wall of the B-pillar and avoiding displacement.

[0041] The working principle of this B-pillar exterior trim panel assembly structure is as follows: the top and bottom of the exterior trim panel can be fixed during installation by the mounting sleeve 104 and the mounting screw 105, and the center position of the exterior trim panel can be fixed by the mounting tube 202, the telescopic tube 203, and the locking plate 201. This achieves the function of three-point installation and fixing of the exterior trim panel. The three-point installation and fixing method greatly increases the stability of the exterior trim panel during use, avoiding the situation where the exterior trim panel shakes and generates noise and increases wind resistance due to airflow during vehicle movement. The stainless steel spring 109 increases the overall toughness of the exterior trim panel during use, avoiding the situation where the surface of the exterior trim panel dents and deforms during long-term use, affecting the overall aesthetics.

[0042] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
