Description

Technical Field

[0001] The utility model generally relates to a sealing mechanism for a covering system of a transportation vehicle. Background Art

[0002] Pickup trucks have traditionally been a widely used vehicle for transporting both cargo and passengers. Passengers are typically seated in the truck cab, while cargo can be stored in the truck bed. Truck beds are typically rectangular and open to the environment, making them convenient for loading and transporting large and / or oddly shaped cargo. However, exposing the truck bed to the elements can leave it and / or cargo unprotected. For example, the truck bed and / or cargo may be exposed to dust, precipitation (e.g., rain, snow, hail), and other hazards. Therefore, some truck owners purchase truck covers to protect the truck bed and the items stored in the truck.

[0003] Existing truck cover systems have several drawbacks during use, including: 1. The cover system utilizes a single, integral cover panel, which cannot be partially folded open or closed, resulting in a relatively limited user experience. 2. The cover system utilizes multiple movable panels (cover panels). Patent application number US18 / 172891 shows that two adjacent panels are connected by hinges. However, due to the lack of a sealing structure at the hinges, rainwater can seep into the vehicle compartment through the gap between the hinges and panels, as well as through the hinges themselves, causing corrosion to items stored inside. 3. The existing technology utilizes a relatively limited distribution area for the sealing mechanism, meaning that only good sealing can be achieved in a localized area, but cannot guarantee a superior seal between the entire vehicle cover system and the vehicle compartment. Summary of the Invention

Therefore, they cannot be understood as limitations on the present invention.

[0050] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0051] Reference Figures 1 to 15 A sealing mechanism 4 for a vehicle covering system 1 includes a vehicle frame mechanism 11 configured to be mounted on a vehicle vehicle compartment 2, wherein the vehicle compartment frame mechanism 11 encloses an open large cavity 11a. In a specific embodiment, referring to Figures 1 to 4 The car body frame mechanism 11 is rectangular in shape, matching the shape of most vehicle bodies 2 on the market. Specifically, the car body frame mechanism 11 includes a front transverse frame 111 disposed on the front edge of the vehicle body 2, a rear transverse frame 112 disposed on the rear edge of the vehicle body 2, and longitudinal subframes 113 disposed on the left and right edges of the vehicle body 2, with the longitudinal subframes 113 located between the front transverse frame 111 and the rear transverse frame 112. Preferably, the car body frame mechanism 11 also includes corner connecting members 114 fixed to the front transverse frame 111 / rear transverse frame 112, and the corner connecting members 114 rest on the longitudinal subframes 113 to form an integral car body frame mechanism 11. If the corner connecting members 114 are removed, the connection between the longitudinal subframe 113 and the front transverse frame 111 / rear transverse frame 112 can be released, allowing the frames to be disassembled.

[0052] The cover system 3 is mounted on the carriage frame mechanism 11 and is used to cover the open large cavity 11a; Figures 1 to 3 The covering system 3 includes a plurality of movable covering frame mechanisms 31 and a cover plate 32 installed in each covering frame mechanism 31. The covering frame mechanism 31 divides the large cavity into a plurality of small cavities 32a. When each small cavity 32a is equipped with a cover plate 32, the large cavity is completely covered by the plurality of cover plates 32. A movable gap 321 is formed between adjacent covering frame mechanisms 31 to meet the movable requirements of the covering frame mechanism 31, so that the covering system 3 has at least an expanded position state 3a and a stored position state 3b relative to the carriage frame mechanism 11. Specifically, referring to Figure 1 When the cover system 3 is in the expanded position 3a, each cover frame mechanism 31 (covering plate 32) is laid flat on the carriage frame mechanism 11 (vehicle carriage 2), closing the large cavity; Figure 2 When the covering system 3 is in the storage position state 3b, part or all of the covering frame mechanism 31 (covering plate 32) is separated from the carriage frame mechanism 11 (vehicle carriage 2), releasing the large cavity partially or completely.

[0053] It should be emphasized that the sealing mechanism 4 is also included. Specifically, refer to Figures 4 to 15 The sealing mechanism 4 includes a longitudinal sealing strip 41, an upper transverse sealing strip 42, a first lower transverse sealing strip 44, and a second lower transverse sealing strip 45. The longitudinal sealing strip 41 is disposed between the longitudinal base frame 113 and the cover frame mechanism 31, the upper transverse sealing strip 42 is laid between adjacent cover plates 32 and blocks the movable gap 321, the first lower transverse sealing strip 44 is disposed between the front transverse frame 111 and the cover frame mechanism 31, and the second lower transverse sealing strip 45 is disposed between the rear transverse frame 112 and the cover frame mechanism 31.

[0054] The above-described sealing structure provides comprehensive waterproofing for the vehicle compartment 2. First, the longitudinal sealing strip 41, the first lower transverse sealing strip 44, and the second lower transverse sealing strip 45 work together to form an effective sealing line in all directions between the compartment frame mechanism 11 and the vehicle compartment 2, preventing rainwater from penetrating into the interior of the vehicle compartment 2 in both the horizontal and vertical directions. Second, the upper transverse sealing strip 42 is used to seal the movable gap 321 between adjacent cover frame mechanisms 31, preventing rainwater from penetrating into the interior of the vehicle compartment 2 through the movable gap 321.

[0055] The embodiment may also include one or more of the following features. The cover frame mechanism 31 includes: Figure 4One or more transverse cover frames 311 are positioned between the left and right longitudinal base frames 113. Multiple longitudinal cover frames 312 are positioned above the longitudinal base frames 113, with the longitudinal cover frames 312 being spliced ​​between two adjacent transverse cover frames 311. This creates a complete cover frame mechanism 31. The cover frame mechanism 31 can be one or more, with a corresponding number of transverse cover frames 311 and longitudinal cover frames 312 selected based on the number of cover frame mechanisms 31.

[0056] According to the above embodiment, the matching structure between the cover plate 32 and the carriage frame mechanism 11 can be: Figure 10 The transverse cover frame 311 and the longitudinal cover frame 312 each have mounting grooves 33. The edges of the cover plate 32 fit into the mounting grooves 33, allowing the cover plate 32 to fit onto the cover frame mechanism 31. This provides a detachable connection between the cover plate 32 and the transverse cover frame 311 / longitudinal cover frame 312. If any components are damaged, the cover plate 32, the transverse cover frame 311, or the longitudinal cover frame 312 can be disassembled for maintenance or replacement.

[0057] In some optional structural embodiments, refer to Figure 9 The longitudinal covering frame 312 has a positioning notch 312a at one end close to the transverse covering frame 311, and the end of the transverse covering frame 311 is inserted into the positioning notch 312a, which has a quick positioning effect, so that the transverse covering frame 311 and the longitudinal covering frame 312 are enclosed with each other to form the small cavity 32a.

[0058] Reference Figures 5 to 7, the arrangement of the longitudinal sealing strip 41 is further described. The longitudinal sealing strip 41 is located between the longitudinal base frame 113 and the longitudinal cover frame 312. Under the action of gravity, the longitudinal cover frame 312 presses the longitudinal sealing strip 41 against the longitudinal cover frame 312. More specifically, the longitudinal sealing strip 41 has a second longitudinal sealing lip 412. The second longitudinal sealing lip 412 is inclined downward from the inside to the outside, and the second longitudinal sealing lip 412 is located on the inner side of the first longitudinal sealing lip 411. Under the action of gravity, the longitudinal cover frame 312 presses the second longitudinal sealing lip 412 of the longitudinal sealing strip 41 against the longitudinal cover frame 312. When rainwater falls on the second longitudinal sealing lip 412, it can be guided by the second longitudinal sealing lip 412 and discharged outward and downward to the outside of the transport covering system 1. The first longitudinal sealing lip 411 and the second longitudinal sealing lip 412 cooperate with each other, can be deformed when subjected to force and are always in contact with the longitudinal covering frame 312, thereby playing a dual water-guiding function; the upper end of the longitudinal base frame 113 is provided with a raised portion 113a, and the raised portion 113a is tightly fitted with the longitudinal sealing strip 41.

[0059] Reference Figures 7 to 11 The arrangement of the upper transverse sealing strip 42 is further described. The movable gap 321 is formed between two adjacent transverse cover frames 311. The upper transverse sealing strip 42 is assembled on the transverse cover frame 311 and blocks the movable gap 321. More specifically, the lower end of the upper transverse sealing strip 42 has a strip-shaped sealing mounting portion 421. The transverse cover frame 311 is provided with a sealing mounting groove 311b. The strip-shaped sealing mounting portion 421 is inserted into the sealing mounting groove 311b, so that the upper transverse sealing strip 42 is engaged with the transverse cover frame 311. Since the strip-shaped sealing mounting portion 421 has its own sealing performance, it forms a dense effect when combined with the sealing mounting groove 311b, and rainwater cannot penetrate into the vehicle compartment 2 through the sealing mounting groove 311b. On the other hand, the longitudinal side edge of the upper transverse sealing strip 42 is bent downward to form a sealing crimping portion 422, which fits tightly against the upper end surfaces of the transverse cover frame 311 and the longitudinal cover frame 312 to prevent the edges from warping, eliminate gaps, and achieve a good sealing effect.

[0060] It should be noted that, referring to Figure 10 The cooperation between the upper transverse sealing strip 42 and the two adjacent longitudinal cover frames 312 not only plays a sealing role, but also forms a structure similar to a hinge, so that the adjacent cover frame mechanisms 31 can be turned over and moved.

[0061] Implementations may also include one or more of the following features. Figure 7 、 Figure 9A frame gap 312c is formed between the two adjacent longitudinal covering frames 312. The existence of the frame gap 312c is to eliminate the structural interference between the two adjacent covering frame mechanisms 31 and provide sufficient space for movement. In order to prevent rainwater from seeping from the frame gap 312c, the sealing mechanism 4 also includes a supplementary sealing strip 43, and the supplementary sealing strip 43 is stuck in the frame gap 312c. A more complete structural description of the supplementary sealing strip 43 is: the longitudinal side edges of the supplementary sealing strip 43 are in contact with the two longitudinal covering frames 312 respectively, the upper end face of the supplementary sealing strip 43 is in contact with the upper transverse sealing strip 42, and the lower end face of the supplementary sealing strip 43 is in contact with the longitudinal base frame 113. Further, referring to Figure 11 The longitudinal sealing strip 41 and the upper transverse sealing strip 42 are interlaced with each other to form an overlapping sealing area 413, and the supplementary sealing strip 43 is located in the overlapping sealing area 413, forming a multi-layer sealing structure, which has a more superior sealing performance.

[0062] In some optional structural embodiments, the sealing mechanism 4 in the present disclosure is made of a flexible material, such as rubber; the carriage frame mechanism 11 is made of a hard material, such as aluminum alloy or other metal materials; the cover plate 32 can be made of a flexible material, such as artificial leather or other materials, or it can be made of a hard material, such as hard plastic or aluminum alloy or other materials.

[0063] Reference Figures 12 and 13 The first lower transverse sealing strip 44 is disposed below the front transverse frame 111 and includes a front straight sealing portion 441, a circular sealing portion 442, and a front transverse sealing lip 443. The upper end surface of the front straight sealing portion 441 always maintains contact with the front transverse frame 111 to provide a local seal. Under pressure, the circular sealing portion 442 can adaptively deform so that the lower end of the circular sealing portion 442 always contacts and seals the vehicle compartment 2. The front transverse sealing lip 443 is inclined downward from back to front. When rainwater falls on the front transverse sealing lip 443, it can be guided by the front transverse sealing lip 443 and discharged outward and downward to the outside of the vehicle cover system 1, effectively preventing rainwater from entering the vehicle compartment 2 from the position between the front transverse frame 111 and the vehicle compartment 2.

[0064] Reference Figures 14 and 15The second lower transverse sealing strip 45 is arranged below the rear end transverse frame 112, and the second lower transverse sealing strip 45 includes a rear end straight sealing portion 451, a first rear end transverse sealing lip 452 and a second rear end transverse sealing lip 453. The upper end surface of the rear end straight sealing portion 451 always maintains contact with the rear end transverse frame 112 to play a local sealing role; the lower ends of the first rear end transverse sealing lip 452 and the second rear end transverse sealing lip 453 are both in contact with the vehicle compartment 2, and the first rear end transverse sealing lip 452 and the second rear end transverse sealing lip 453 are both inclined downward from back to front. The size of the second rear end transverse sealing lip 453 is larger than that of the first rear end transverse sealing lip 452, and the second rear end transverse sealing lip 453 is located in front of the first rear end transverse sealing lip 452. Under this structure, the water-blocking ability of the second rear end transverse sealing lip 453 is stronger than that of the first rear end transverse sealing lip 452. Therefore, even if the sealing performance of the first rear end transverse sealing lip 452 is insufficient in encountering heavy rain, the sealing performance of the second rear end transverse sealing lip 453 can still achieve a good water-blocking effect. When rainwater falls onto the first rear transverse sealing lip 452 or the second rear transverse sealing lip 453, it can be guided outward and downward to the outside of the vehicle cover system 1, effectively preventing rainwater from entering the interior of the vehicle compartment 2 from the position between the rear transverse frame 112 and the vehicle compartment 2. At the same time, the first rear transverse sealing lip 452 and the second rear transverse sealing lip 453 form two rainwater blocking lines, thereby achieving a dual waterproof and sealing effect.

[0065] It is worth noting that other technical solutions of the present invention belong to the existing technology and are therefore not described in detail.

[0066] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
