[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] Refer to Figure 1 、 Figure 3 and Figure 4, an embodiment provided by the present utility model: a reinforced door sealing strip, including a sealing strip body 1, which is made of rubber with good elasticity and anti-compression deformation ability and can maintain stable performance in various environments. A clamping groove 2 in contact with the outer edge of the vehicle door is formed on the front surface of the sealing strip body 1. A clamping block 3 is fixedly connected to the inner wall on the right side of the clamping groove 2. There are three groups of clamping blocks 3, which are linearly and evenly distributed on the inner wall on the right side of the clamping groove 2. The end of the clamping block 3 inclines towards the inside of the clamping groove 2, and the end of the clamping block 3 contacts the outer side of the outer edge of the vehicle door. When pulling out the sealing strip body 1 outward, the clamping block 3 contacts the outer edge of the vehicle door, generating resistance to prevent the sealing strip body 1 from detaching. A sealing strip 4 bends towards the clamping groove 2 and extends forward on the front surface of the sealing strip body 1. After the clamping groove 2 is clamped with the outer edge of the vehicle door, the sealing strip 4 blocks the opening of the clamping groove 2, reducing the entry of dust and rainwater into the clamping groove 2 and increasing the waterproof and dustproof performance. A U-shaped steel bar 5 is fixedly connected inside the sealing strip body 1. The U-shaped steel bar 5 has certain elasticity and plasticity. When the opening of the U-shaped steel bar 5 opens to both sides, the U-shaped steel bar 5 will generate an elastic force to restore to its original state inward. When the U-shaped steel bar 5 is bent as a whole along the shape of the door, the U-shaped steel bar 5 has certain plasticity to keep its bent shape unchanged. The clamping groove 2 is located inside the opening of the U-shaped steel bar 5. After the clamping groove 2 opens, the U-shaped steel bar 5 will provide an inward clamping force. A cross-sealing hole 6 is formed on the inner wall on the left side of the clamping groove 2. When not under force, the inner walls of the holes of the cross-sealing hole 6 are in contact with each other to keep it sealed. A receiving groove 7 is formed inside the sealing strip body 1. The receiving groove 7 is located inside the opening of the U-shaped steel bar 5. When the clamping groove 2 contacts the outer edge of the vehicle door, the U-shaped steel bar 5 will deform and squeeze the receiving groove 7. There are multiple groups of cross-sealing holes 6 and receiving grooves 7. The left side of the cross-sealing hole 6 is connected to the right side of the receiving groove 7. An adhesive 8 is placed inside the receiving groove 7. When the clamping groove 2 is squeezed, the cross-sealing hole 6 will deform and at the same time a gap will appear, causing the adhesive 8 inside the receiving groove 7 to flow out from the cross-sealing hole 6. A covering film 9 is adhered to the inner wall on the left side of the clamping groove 2. The covering film 9 prevents the cross-sealing hole 6 from being squeezed open during transportation.

[0030] Refer to Figure 2, a sound insulation cavity 10 is provided inside the sealing strip body 1. The sound insulation cavity 10 can utilize the characteristics of rubber and the cavity to absorb the noise in the environment. An extension foot 11 extends from the left inner wall of the sound insulation cavity 10 towards the center. A V-shaped rubber strip 12 is fixedly connected to the position on the inner wall of the sound insulation cavity 10 opposite to the extension foot 11. Both the extension foot 11 and the V-shaped rubber strip 12 are made of rubber and have certain elasticity and deformation ability. The V-shaped rubber strip 12 is set as a V shape with the opening facing left, and a group of arms extend obliquely towards the front and rear sides respectively. There are two groups of extension feet 11, and the two groups of extension feet 11 are symmetrically arranged front and rear. When the inner side of the vehicle of the sealing strip body 1 is squeezed, the sound insulation cavity 10 is compressed, driving the extension foot 11 to move, so that the right ends of the two groups of extension feet 11 are respectively in contact with the left sides of a group of arms of the V-shaped rubber strip 12.

[0031] Working principle: When it is desired to make the sealing strip body 1 flush with the door sheet metal, first tear off the covering film 9, and then insert the outer edge of the vehicle door into the inside of the clamping groove 2. The clamping groove 2 is squeezed by the outer edge of the vehicle door and opens to both sides. At the same time, the U-shaped steel strip 5 generates an elastic force and clamps inward. At this time, the U-shaped steel strip 5 will squeeze the accommodating groove 7, causing the cross-sealing holes 6 to open gaps. The adhesive 8 inside the accommodating groove 7 flows out through the gaps of the cross-sealing holes 6 and contacts the outer edge of the vehicle door, bonding the sealing strip body 1 and the outer edge of the vehicle door together, making the sealing strip body 1 fit better with the outer edge of the vehicle door. It is not easy to deform after long-term use, ensuring sound insulation and isolation. When it is desired to improve the sound insulation effect of the sealing strip body 1, the extension foot 11 and the V-shaped rubber strip 12 are arranged inside the sound insulation cavity 10. The vehicle door and the B-pillar squeeze the sealing strip body 1 when the vehicle door is closed, causing the sound insulation cavity 10 to deform. The sound insulation cavity 10 is compressed, driving the extension foot 11 to contact the V-shaped rubber strip 12, so that the inside of the sound insulation cavity 10 is divided into multiple groups of cavities by the extension foot 11 and the V-shaped rubber strip 12, thereby reducing and improving the sound insulation effect. At the same time, the extension foot 11 and the V-shaped rubber strip 12 are designed to be disconnected, reducing the resistance generated by the sealing strip body 1 when the door is closed and preventing the vehicle door from not closing tightly.
