Description

Technical Field

[0001] The utility model relates to the technical field of sealing strips, in particular to a new type of automobile sealing strip. Background Art

[0002] Automobile sealing strips have the function of filling various gaps and crevices between the components of the vehicle body, and have functions such as shock absorption, waterproofing, dustproofing, sound insulation, decoration, etc., improving the comfort of the driving experience and protecting the vehicle body.

[0003] In the prior art, the sealing strips used at the automobile windows are often made of rubber materials, and their designs are often relatively simple. When facing heavy rain or vibrations generated during vehicle driving, rainwater or dust easily penetrates into the vehicle, resulting in a decline in the sealing performance and affecting the waterproof and dustproof effects inside the vehicle. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that the existing automobile sealing strip has a relatively simple design and poor waterproof and dustproof effects.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: a new type of automobile sealing strip, including a sealing strip base body. A connecting column is provided at the lower end of the sealing strip base body, and a connecting convex strip for connecting with the window is provided at the bottom of the connecting column. An inner retaining strip and an outer retaining strip are provided at the upper end of the sealing strip base body. An insertion slot for inserting the window glass is provided between the inner retaining strip and the outer retaining strip. Two extrusion strips are provided on each side of the inner retaining strip and the outer retaining strip close to the insertion slot.

[0006] As a further improvement of the utility model, the sealing strip base body is made of rubber material, and the sealing strip base body, the connecting column, the connecting convex strip, the inner retaining strip, the outer retaining strip, and the extrusion strip are of an integrated structure.

[0007] As a further improvement of the utility model, a plurality of tooth-shaped structures with alternating concave and convex are provided on both side surfaces of the connecting column.

[0008] As a further improvement of the utility model, a first cavity is provided inside the connecting convex strip, and a second cavity is provided inside the inner retaining strip.

[0009] As a further improvement of the utility model, a first buffer cavity is provided inside the sealing strip base body and the first buffer cavity is located below the insertion slot, and a second buffer cavity is provided inside the outer retaining strip.

[0010] As a further improvement of the utility model, the top of the inner retaining strip is designed with a rounded corner, and the top of the outer retaining strip is designed with a sharp corner and is inclined towards the insertion slot.

[0011] As a further improvement of the utility model, the end of the extrusion strip points to the inside of the insertion slot, and adsorption grooves are provided on the surface of the extrusion strip.

[0012] Advantages of the utility model: (1) The insertion slot designed between the inner retaining strip and the outer retaining strip of the utility model, and the two extrusion strips added on one side of both near the insertion slot not only provide a stable insertion space for the window glass, but also can closely fit the glass surface through the elastic deformation of the extrusion strips when the window is closed, effectively preventing the intrusion of rainwater and dust. This dual protection mechanism greatly enhances the sealing effect of the sealing strip. Even in bad weather or when the vehicle is driving at high speed with strong vibrations, it can keep the interior environment clean and dry.

[0013] (2) The sealing strip base body of the utility model and its various components (connecting columns, connecting ridges, inner retaining strips, outer retaining strips, extrusion strips) are designed with an integrated rubber material, which not only simplifies the production process, improves the integrity and durability of the product, but also ensures seamless connection between components, further enhancing the sealing performance. At the same time, the excellent elasticity of the rubber material enables the sealing strip to better adapt to the minor deformation of the window and maintain a long-term stable sealing effect.

[0014] (3) The toothed structure design on both sides of the connecting columns of the utility model not only increases the friction with the window installation position, improves the stability of the sealing strip installation, but also can absorb the vibration energy during vehicle driving to a certain extent, reduce noise transmission, and improve the riding comfort. The first cavity and the second cavity provided inside the connecting ridge and the inner retaining strip serve as additional buffer spaces, further enhancing the shock absorption effect of the sealing strip and protecting the window and its surrounding components from damage.

[0015] (4) The design of the first buffer cavity inside the sealing strip base body and the second buffer cavity inside the outer retaining strip of the utility model can form an additional air barrier when the window is closed, effectively isolating the influence of external noise and temperature changes on the interior environment. At the same time, these buffer cavities can also absorb part of the impact force when the vehicle is impacted, protecting the safety of the passengers.

[0016] (5) The rounded corner design at the top of the inner retaining strip of the utility model makes it smoother and unobstructed when contacting the window glass, reducing the noise and wear caused by friction; the pointed corner design at the top of the outer retaining strip inclined towards the insertion slot can facilitate the downward flow of rainwater, avoid rainwater seeping into the vehicle body, improve the waterproof effect, and optimize the appearance aesthetics. The adsorption grooves provided on the surface of the extrusion strip enhance its adsorption force on the window glass, further improving the sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] The present utility model provides a new type of automotive sealing strip as shown in the attached Figure 1 and Figure 2 figure, which includes a sealing strip base body 1. A connecting column 2 is provided at the lower end of the sealing strip base body 1. A connecting rib 3 for connecting with the vehicle window is provided at the bottom of the connecting column 2. An inner retaining strip 4 and an outer retaining strip 5 are provided at the upper end of the sealing strip base body 1. An insertion slot 6 for inserting the vehicle window glass is provided between the inner retaining strip 4 and the outer retaining strip 5. Two extrusion strips 7 are provided on both sides of the inner retaining strip 4 and the outer retaining strip 5 close to the insertion slot 6.

[0024] In the present utility model, the sealing strip base body 1 is made of rubber material, and the sealing strip base body 1, the connecting column 2, the connecting rib 3, the inner retaining strip 4, the outer retaining strip 5, and the extrusion strip 7 are of an integrated structure.

[0025] Such as Figure 1 and Figure 2As shown in the figure, on both sides of the connecting column 2 in the present utility model, there are provided a plurality of tooth-shaped structures with alternating concave and convex parts. Inside the connecting rib 3, there is a first cavity 8. Inside the inner retaining strip 4, there is a second cavity 9. Inside the sealing strip matrix 1, there is a first buffer cavity 10 and the first buffer cavity 10 is located below the insertion slot 6. Inside the outer retaining strip 5, there is a second buffer cavity 11. The top of the inner retaining strip 4 is designed with a rounded corner. The top of the outer retaining strip 5 is designed with a pointed corner and is inclined towards the insertion slot 6. The end of the extrusion strip 7 points towards the inside of the insertion slot 6 and there are adsorption grooves 12 on the surface of the extrusion strip 7.

[0026] Working principle: When the present utility model is specifically implemented, the sealing strip will be installed on the top of the car window through the connecting rib 3. During the installation process, due to the tooth-shaped structure design on both sides of the connecting column 2, during the installation of the sealing strip, by increasing the friction force with the installation position of the car window, it ensures that the sealing strip can be firmly fixed on the car window, is not easy to loosen or fall off, not only improves the safety during driving, but also extends the service life of the sealing strip.

[0027] When the car window glass needs to be closed, the car window glass will slide upwards. When the car window glass is almost closed, it will slide inwards along the insertion slot 6 until the car window glass is completely inserted into the insertion slot 6 between the inner retaining strip 4 and the outer retaining strip 5. During this process, due to their elastic design, the two extrusion strips 7 will contact the edge of the car window glass and undergo slight elastic deformation as the car window glass is further inserted, so as to closely fit on the glass surface, effectively preventing the intrusion of rainwater and dust, and also enhancing the sealing effect through physical extrusion, ensuring the cleanliness and dryness of the interior environment of the vehicle. At the same time, the adsorption grooves 12 provided on the surface of the extrusion strip 7 enhance the adsorption force of the sealing strip on the car window glass, making the sealing effect more remarkable.

[0028] With the complete closing of the car window, the first buffer cavity 10, the second buffer cavity 11 and the second cavity 9 will form a short air compression process at the moment when the car window is closed, further enhancing the sealing effect of the sealing strip on the car window, and at the same time providing a buffer for possible minor vibrations or impacts, reducing the transmission of noise and the fluctuation of the interior environment of the vehicle.

[0029] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
