[0024] The utility model can be explained in detail through the following examples, the purpose of the utility model is to protect all technical improvements within the scope of the utility model, in the description of the utility model, it needs to be understood that, if there are terms "upper", "lower", "front", "rear", "left", "right" and so on indicate the orientation or position relationship, only corresponds with the drawing of the present application, in order to facilitate the description of the utility model, and it is not indicated or implied that the device or element must have a particular orientation.

[0025] Embodiment 1, in conjunction with the accompanying drawings Figs. 1-3 A double-sealing aluminum profile for sealing the gap between the upper compartment plate 5 and the lower compartment plate 6 of the vehicle compartment. The double-sealing aluminum profile comprises a first fastener 1, a sealing strip 2 and a second fastener 3. The first fastener 1 is fastened to the top of the lower compartment plate 6, and the fastening part adopts a right-angle bent structure. This structure enables the vertical edge of the first fastener 1 to be tightly fastened to the outer side of the lower compartment plate 6, thereby forming a stable connection. This tight fastening method not only effectively prevents rainwater from entering, but also enhances the stability of the entire structure, ensuring that it will not loosen during vehicle travel.

[0026] On the top of the horizontal edge of the fastening part of the first fastener 1, a plurality of clamping grooves are provided. These clamping grooves are arranged at certain intervals, and each clamping groove is embedded with a sealing strip 2. In this embodiment, the number of clamping grooves and sealing strips 2 is two, and the sealing strips 2 from the outer side to the inner side of the vehicle compartment are a bubble sealing strip and a rectangular sealing strip in sequence. The bubble sealing strip has good elasticity and can effectively fill irregular gaps, while the rectangular sealing strip provides a wider sealing contact surface. The combination of the two forms a double-sealing defense line, greatly improving the reliability of the seal.

[0027] In addition, the inner side of the horizontal edge of the fastening part of the first fastener 1 is integrally connected with an upwardly arranged inclined blocking edge corresponding to the inner side of the lower compartment plate 6. This inclined blocking edge is the last line of defense in the entire sealing system, effectively preventing rainwater from entering the vehicle compartment.

[0028] On the bottom of the upper compartment plate 5, the second fastener 3 is fastened. The second fastener 3 also adopts a right-angle bent structure, and its vertical edge is fastened to the outer side of the upper compartment plate 5. In response to the first fastener 1, the vertical edge of the second fastener 3 and the vertical edge of the first fastener 1 are both located on the outside of the vehicle compartment. This design not only enhances the structural strength of the upper compartment plate 5 and the lower compartment plate 6, but also cleverly hides the edge parts of the upper compartment plate 5 and the lower compartment plate 6. In this way, the edges of the upper compartment plate 5 and the lower compartment plate 6 are protected from collision damage, and the overall aesthetics are improved.

[0029] The horizontal edge bottom of the second fastener 3 is provided with protrusions corresponding to the positions of the plurality of sealing strips 2. When the upper compartment plate 5 and the lower compartment plate 6 are connected correspondingly, the protrusions will precisely press on the corresponding sealing strips 2, further enhancing the sealing effect. This design enables the sealing strips 2 to be more tightly fitted in the clamping groove while being pressed by the protrusions, thereby effectively preventing dust and rainwater from entering the interior of the compartment, ensuring the cleanliness and dryness of the interior environment of the compartment.

[0030] In summary, the double-sealed aluminum profile of the present embodiment forms a high-efficiency and reliable sealing system through the synergistic effect of the first fastener 1, the sealing strip 2, and the second fastener 3. It not only effectively prevents external environmental factors from affecting the interior of the compartment, but also has the advantages of stable structure, aesthetic appearance, etc., making it an excellent solution in the field of compartment sealing.

[0031] Embodiment 2, combined with the attached Figs. 1-2 A double-sealed aluminum profile is further optimized and designed. Compared with Embodiment 1, this embodiment retains the original structural advantages and innovatively improves the slope barrier, making it have more functional characteristics.

[0032] The slope barrier adopts a hollow structure design, which can effectively reduce the overall weight of the first fastener 1, reduce the use of materials without reducing the structural strength, conform to the lightweight design trend, and reduce production costs.

[0033] Further, the slope surface of the slope barrier is provided with an opening corresponding to the internal cavity, and one end of the slope barrier is sealed and the other end is connected with a drain valve. This design cleverly solves the problem of rainwater possibly entering the interior of the compartment. Even if rainwater penetrates the defense line of the plurality of sealing strips 2 and enters the interior of the compartment under extreme weather conditions, it will flow smoothly into the cavity of the slope barrier along the opening on the slope surface of the slope barrier. Since the opening is connected with the cavity, rainwater will not flow randomly on the interior wall of the compartment, avoiding the risk of damaging the interior structure and goods of the compartment.

[0034] The operator only needs to open the drain valve regularly to conveniently check whether there is rainwater accumulated in the cavity of the slope barrier. If water is found, the rainwater can be drained through the drain valve in time to ensure that the interior of the compartment remains dry. This design not only improves the safety of the compartment, but also facilitates daily maintenance and management, reduces the problems of corrosion and mildew caused by rainwater accumulation, and prolongs the service life of the compartment.
