Description

Technical Field

[0001] The utility model relates to a waterproof and dustproof automobile back door storage box. Background Art

[0002] With the rapid development of the automotive industry, car tailgate storage boxes have become a convenient storage device for tools or personal items. However, traditional car tailgate storage boxes on the market still have the following technical defects during use:

[0003] Most existing storage box designs fail to adequately seal the storage space from the outside environment. In rainy or snowy weather, or while the vehicle is driving, moisture can seep into the storage space through the gap between the lid and the box body, causing items inside the box to become damp or even damaged.

[0004] The sealing design of traditional storage boxes is relatively simple, and there is often a gap at the connection between the lid and the box body, which easily allows small particles such as dust and sand to enter the storage box. This problem is particularly prominent in harsh environments, such as deserts or dirt roads, and has a negative impact on the user experience of the items in the storage box. Utility Model Content

[0005] The purpose of the utility model is to provide a waterproof and dustproof car tailgate storage box which significantly improves the waterproof and dustproof performance of the storage box.

[0006] The purpose of this utility model is achieved in this way:

[0007] A waterproof and dustproof car tailgate storage box comprises a box body and a box lid, wherein the inner cavity of the box body is a storage space, a surface of the box body is provided with an opening communicating with the storage space, the box lid is hinged to the box body, and the box lid rotates about the hinge as a rotation center to open or close the storage space, and further comprises a first rubber strip and a second rubber strip, wherein the first rubber strip is provided on the box body and positioned at the periphery of the storage space, and the second rubber strip is provided on the box body and positioned at the periphery of the storage space, and the first rubber strip is positioned above the second rubber strip;

[0008] When the box cover is rotated to close the storage space, the box cover is in close contact with the first rubber strip and the second rubber strip, and the first rubber strip and the second rubber strip respectively seal the connection gap between the box cover and the box body.

[0009] This invention achieves excellent waterproof and dustproof performance through a double-layer rubber strip design. When the lid is closed, the first and second rubber strips are compressed to half their original thickness, forming a tight double seal. The first rubber strip primarily protects against dust and mud, effectively preventing dust, sand, and mud from entering the storage space. The second rubber strip acts as a waterproof seal, further preventing rainwater and other liquids from seeping in, significantly enhancing the storage box's waterproofing.

[0010] The double-layer protective structure provides a high degree of sealing performance while fully utilizing the elasticity of the rubber strips to ensure even pressure distribution when the lid is closed. This ensures a good seal while preventing premature aging of the rubber strips due to excessive compression. Furthermore, the first and second rubber strips have clear divisions of labor and complement each other, significantly enhancing the storage box's adaptability in a variety of harsh environments. Whether in rain, snow, muddy roads, or dusty environments, they effectively protect items within the storage space from contamination or damage.

[0011] This design achieves efficient sealing while ensuring smooth opening and closing of the lid. The strategic placement of the double-layered adhesive strips minimizes operational resistance while maintaining a beautiful and consistent gap between the lid and the body, further enhancing the practicality and aesthetics of the storage box. This optimized two-layer waterproof structure significantly improves the reliability, durability, and user experience of automotive tailgate storage boxes, making them suitable for a wide range of applications.

[0012] The purpose of the utility model can also be solved by the following technical measures:

[0013] Furthermore, the first adhesive strip is adhered to the box body.

[0014] Furthermore, the first rubber strip is a hollow rubber strip.

[0015] By designing the first rubber strip as a hollow strip, the sealing performance and user experience are further optimized. The hollow rubber strip has excellent elasticity and flexibility, which can better adapt to the contact pressure between the box lid and the box body when the box lid is closed, providing a stable and uniform sealing effect, while also preventing deformation or failure of the rubber strip due to excessive compression.

[0016] The hollow structure allows the first rubber strip to maintain its excellent resilience even when compressed to half its original thickness. This not only ensures dust and mud resistance, but also effectively disperses the pressure when the lid is closed, extending the service life of the rubber strip. Furthermore, the hollow design reduces the overall weight of the rubber strip, reducing the overall load of the storage box, and improving portability and economy.

[0017] The soft nature of the hollow rubber strip can also enhance the contact fit between the box lid and the box body, ensuring that the sealing effect of the storage box is not affected regardless of extreme environments such as high and low temperatures, humidity or dryness, thereby further improving the adaptability and reliability of the storage box.

[0018] Furthermore, the box body is provided with convex ribs on the periphery of the storage space, the second rubber strip is provided with a clamping groove, the convex ribs are inserted into the clamping groove, and the second rubber strip is clamped on the box body.

[0019] By setting convex ribs on the outer periphery of the box body and using a second rubber strip with a clamping groove, the stable fixation of the second rubber strip is achieved, and at the same time, the sealing performance is further enhanced. The convex ribs are inserted into the clamping groove, enabling the second rubber strip to be firmly clamped on the box body, effectively avoiding the problem of rubber strip loosening caused by long-term use or environmental vibration, and improving the overall reliability of the storage box.

[0020] Furthermore, elastic ribs for increasing the clamping effect are arranged in the inner cavity of the clamping groove towards its central position. The convex ribs are inserted into the clamping groove, and the elastic ribs are closely attached to the convex ribs.

[0021] When the convex ribs are inserted into the clamping groove, the elastic ribs are closely attached to the surface of the convex ribs, further improving the stability of the clamping. At the same time, the flexibility of the elastic ribs can adapt to the manufacturing error of the box body, ensuring that the second rubber strip is firmly installed without stress concentration, thereby prolonging the service life of the rubber strip.

[0022] Furthermore, the second rubber strip includes a front rubber strip and a rear rubber strip. The front rubber strip is a hollow rubber strip, and the rear rubber strip is provided with the clamping groove. The front rubber strip and the rear rubber strip are connected together by an integral molding method.

[0023] The design of the second rubber strip adopts an integral molding structure of the front rubber strip and the rear rubber strip. Among them, the front rubber strip is a hollow rubber strip, providing better elasticity and resilience performance, enhancing the sealing effect and dispersing the pressure when the box cover is closed; the rear rubber strip is firmly connected to the box body through the clamping groove, ensuring the stability of the fixed position of the rubber strip and the sealing effect. The integral molding design simplifies the production process, avoids problems such as installation complexity and poor sealing that may be brought by multi-component combination, and at the same time improves the product consistency and processing efficiency.

[0024] Furthermore, the first rubber strip is a "C"-shaped rubber strip.

[0025] The design of the "C"-shaped rubber strip enables the rubber strip to only cover the top and side parts of the storage area, and there is no rubber strip on the box body below the storage area, thereby reducing the use of materials, lowering the production cost, and simplifying the installation process.

[0026] In actual use, rainwater or the water flow when washing the car mainly concentrates on the top or side of the storage box, and the bottom area is usually not directly invaded by the water flow. Therefore, the waterproof performance of the storage box can be ensured without a rubber strip at the bottom. This design fully considers the actual working environment and usage requirements of the storage box, avoids material waste through reasonable structural optimization, and reflects the balance between economy and practicality.

[0027] The design of the "C"-shaped rubber strip not only saves materials but also retains the good sealing performance of the storage box. When the box cover is closed, the first rubber strip on the top and side can be closely fitted with the second rubber strip, blocking the intrusion of rainwater, dust, and sediment, and effectively protecting the items in the storage space.

[0028] Furthermore, the second rubber strip is a "C"-shaped rubber strip.

[0029] The design of the "C"-shaped rubber strip enables the rubber strip to only cover the top and side parts of the storage area, and there is no rubber strip on the box body below the storage area, thus reducing the use of materials, lowering the production cost, and simplifying the installation process at the same time.

[0030] In actual use, rainwater or the water flow when washing the car mainly concentrates on the top or side of the storage box, and the bottom area is usually not directly invaded by the water flow. Therefore, the waterproof performance of the storage box can be ensured without a rubber strip at the bottom. This design fully considers the actual working environment and usage requirements of the storage box, avoids material waste through reasonable structural optimization, and reflects the balance between economy and practicability.

[0031] The design of the "C"-shaped rubber strip not only saves materials but also retains the good sealing performance of the storage box. When the box cover is closed, the first rubber strip on the top and side and the second rubber strip can fit tightly, blocking the intrusion of rainwater, dust, and sediment, and effectively protecting the items in the storage space.

[0032] The beneficial effects of the present utility model are as follows:

[0033] In the present utility model, excellent waterproof and dustproof performances are achieved through the double-layer rubber strip design. When the box cover is in the closed state, the first rubber strip and the second rubber strip are respectively compressed to 1 / 2 of their original thickness, forming a tight double-sealing structure. Among them, the first rubber strip is mainly used for dust prevention and mud prevention, effectively blocking the entry of dust, sand particles, and mud from the outside into the storage space; the second rubber strip serves as a waterproof sealing layer, further preventing the infiltration of rainwater or other liquids, thereby greatly improving the waterproof effect of the storage box.

[0034] In the present utility model, the design of the "C"-shaped rubber strip enables the rubber strip to only cover the top and side parts of the storage area, and there is no rubber strip on the box body below the storage area, thus reducing the use of materials, lowering the production cost, and simplifying the installation process at the same time.
