[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-4 This utility model provides a tightly fitting automotive pillar assembly, including an adhesive plate 1 and a main pillar 2. The adhesive plate 1 uses thermoplastic polyurethane (TPU) or bio-based TPU as the surface material and a micro-foamed plant fiber composite material with a porous internal structure as the inner lining, which achieves breathability while avoiding local wrinkling caused by uneven fiber arrangement. The main pillar 2 can be a connector connecting the pillar body or it can be the main body of the pillar directly, avoiding the impact on the strength of the pillar due to slotting on the main pillar 2. The main pillar 2 can be an A-pillar or a B-pillar.

[0025] The back of the bonding plate 1 is provided with a fitting groove 3 that is adapted to the main column 2. One side of the main column 2 is provided with four rectangular positioning grooves 4. The inner side wall of the positioning groove 4 is fixedly connected with a fixing frame 5, wherein every two fixing frames 5 are arranged opposite to each other.

[0026] A positioning tube 11 is fixedly connected to the inner wall of the fitting groove 3, and a connecting column 12 is fixedly connected to one side of the main column 2. The positioning tube 11 and the connecting column 12 can assist in the positioning of the bonding plate 1 and the main column 2.

[0027] The inner wall of the fitting groove 3 is provided with a sealing rubber strip, and a sealing groove 13 adapted to the sealing rubber strip is opened on one side of the main column 2. The sealing rubber strip and the sealing groove 13 can be used to strengthen the seal between the bonding plate 1 and the main column 2.

[0028] A positioning mechanism 6 is provided on the bonding plate 1. The positioning mechanism 6 includes four rectangular positioning blocks 61 fixedly connected to the inner wall of the fitting groove 3. A rectangular limiting groove 62 is opened in the positioning block 61. Every two positioning blocks 61 form a group. The opening directions of the limiting grooves 62 of the two positioning blocks 61 are opposite. A positioning rod 64 is fixedly connected to the inner wall of the limiting groove 62. A rectangular limiting block 65 is slidably connected to the outer wall of the positioning rod 64. A spring 63 is sleeved on the outer wall of the positioning rod 64. One end of the limiting block 65 extends out of the limiting groove 62 and is inserted into the fixing frame 5. By setting the positioning mechanism 6, it is easy to replace the existing embedded buckle and ensure the stability of the snap-fit.

[0029] A pressing block 7 is slidably connected inside the fixed frame 5. A magnetic block 8 is fixedly connected to one side of the pressing block 7 near the limiting frame. The magnetic block is made of a metal material that can be attracted by the magnetic block. By setting the pressing block 7 and the magnetic block, it is easy to cooperate with the external magnetic block to release the limiting block 65 from the positioning block 61.

[0030] A stop block 9 is fixedly connected to the inner wall of the fixed frame 5. A through groove adapted to the extrusion block 7 is opened on one side of the stop block 9. The setting of the stop block 9 and the through groove can facilitate the movement and limiting of the magnetic block and the fixed frame 5.

[0031] The inner sidewall of the limiting groove 62 is provided with a sliding groove 10, and a slider is slidably connected in the sliding groove 10. One end of the slider extends out of the sliding groove 10 and is fixedly connected to the limiting block 65. Through the setting of the sliding groove 10 and the slider, the limiting block 65 is moved and limited to prevent the limiting block 65 from disengaging from the positioning block 61.

[0032] The positioning block 61 is tapered at one end inside the fixing frame 5, eliminating the need to manually press the positioning block 61 and simplifying the operation. The inner wall of the positioning groove 4 is provided with a sponge pad to increase resistance.

[0033] Based on the above structure, the present invention includes the following implementation process:

[0034] Press the bonding plate 1 against the main column 2, insert one end of the connecting column 12 into the positioning tube 11 to complete the initial positioning between the bonding plate 1 and the main column 2. Then, the positioning block 61 enters the positioning groove 4 until the inner side wall of the positioning groove 4 at one end of the positioning block 61 abuts. At this time, the limiting groove 62 is aligned with the opening of the fixing frame 5. Under the pressure of the spring 63, one end of the limiting block 65 moves out of the limiting groove 62 and inserts into the fixing frame 5. The end of the limiting block 65 inserted into the fixing frame 5 pushes the squeezing block 7 and the magnetic block to move. The four positioning blocks 61 are in pairs and the snapping direction is opposite. That is, the stability of the tight bonding between the bonding plate 1 and the main column 2 is strengthened by the limiting in two opposing directions, avoiding loosening and wrinkling caused by long-term vibration.

[0035] When it is necessary to replace the bonding plate 1, an external magnetic block can be taken and placed near both sides of the bonding plate 1, corresponding to the position of the fixing frame 5. The magnetic block generates a magnetic attraction force on the magnetic block. The magnetic attraction force between the two should be greater than the pressure of the spring 63, causing the magnetic block to drive the pressing block 7 to move towards the positioning block 61. Push out one end of the positioning block 61 located in the fixing frame 5 to release the limitation of the positioning block 61 in that section. Slightly bend the bonding plate 1 in that section so that the positioning block 61 moves out of the positioning groove 4. Then repeat the operation to release the limitation of the remaining three positioning blocks 61, and the bonding plate 1 can be removed.
