Description

Technical Field

[0001] This utility model relates to a car tailgate cover, belonging to the field of automotive parts. Background Technology

[0002] For some vehicles with open tailgates, such as pickup trucks and vans, a tailgate cover is usually installed on the tailgate. The tailgate cover can protect the cargo inside the tailgate and protect it from rain.

[0003] The existing tailgate covers are usually fixed with bolts, which can lead to insufficient sealing, allowing water to enter the box and causing the internal roller shutter to rust, thus affecting the overall performance and lifespan. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings and deficiencies of the existing technology and to provide a car tailgate cover.

[0005] A car tailgate includes a shell and a roller shutter component disposed inside the shell. The shell includes a base plate with first connecting portions on both sides. The base plate is detachably connected to a first side plate and a second side plate via the first connecting portions. The first and second side plates have second connecting portions for detachable connection with the first connecting portions. The base plate, first side plates, and second side plates are connected and then fixedly connected by a fixing plate to form the overall shape of the shell. The base plate is no longer connected to the first and second side plates using traditional bolts, but rather through pre-set first and second connecting portions for snap-fit ​​or plug-in detachable connection, further reinforced by the fixing plate. After the overall shell is formed, all seams fit tightly, effectively preventing rainwater and dust from seeping in and avoiding water accumulation inside the shell. Excellent sealing performance prevents rainwater or moisture from entering the shell, effectively protecting the internal roller shutter component from moisture corrosion, preventing rust, ensuring smooth opening and closing of the roller shutter, and extending the overall service life of the machine. The detachable connection structure allows for faster installation and disassembly of the entire enclosure. No special tools or cumbersome bolting are required, enabling easy assembly, disassembly, and routine maintenance, significantly reducing maintenance difficulty and costs. Compared to traditional bolt fixing, the use of standardized connectors and mounting plates simplifies the types of parts and facilitates mass production and assembly, reducing overall manufacturing and maintenance costs.

[0006] Preferably, the first connecting part includes a supporting part and a fixing part disposed on the side of the supporting part. The fixing part is C-shaped. The second connecting part is an opening groove that matches the shape of the first connecting part. The first connecting part can be inserted into or removed along the opening of the second connecting part. The C-shaped fixing part and the opening groove fit precisely, forming a self-locking structure similar to a buckle. Under the bumps and impacts generated during vehicle operation, the two are tightly engaged, not easily loosening or slipping, greatly improving connection reliability and vibration resistance. The first connecting part can be directly inserted into or removed along the opening of the second connecting part, without the need for additional tools or complex adjustments, enabling quick installation and disassembly of the side plate and the bottom plate, shortening the assembly cycle and making maintenance more convenient.

[0007] Furthermore, an L-shaped limiting part is provided on one side of the opening of the second connecting part. One end of the limiting part is fitted into the connection between the supporting part and the fixing part, forming a limiting connection for the fixing part. The L-shaped limiting part is fitted into the connection between the supporting part and the fixing part, forming a reliable stopping structure. During the insertion process, the limiting part and the fixing part mesh with each other, which can accurately limit the insertion depth and position of the side plate, avoiding misalignment or loosening caused by vibration or operational deviation. The limiting part forms a secondary physical barrier for the fixing part, which can effectively prevent the fixing part from being accidentally pulled out along the insertion direction even under strong bumps or impacts, further enhancing the self-locking performance and anti-dislodgement ability.

[0008] Furthermore, the support portion and the base plate form an L-shape. The other side of the opening of the second connecting portion abuts against the base plate in the first direction. The end faces of the support portion and the fixing portion abut against the inner wall of the first connecting portion, with their abutting directions parallel to the first direction. The L-shaped structure of the support portion and the base plate allows the connector to fit snugly against the base plate in both vertical and parallel directions. The other side of the opening of the second connecting portion abuts against the base plate, and the parallel abutting of the end faces of the support portion and the fixing portion against the inner wall of the first connecting portion together form multi-faceted support, significantly improving the local structural rigidity and overall load-bearing capacity of the enclosure. The abutting surfaces are perpendicular or parallel to each other, not only fitting tightly but also sealing each other in multiple directions, further reducing the infiltration paths of rainwater and dust, resulting in a more reliable sealing effect.

[0009] Preferably, the base plate, the first side plate, and the second side plate are provided with a third connecting part, which is arranged in a C-shaped bend. The fixing plate is fixedly connected to the fixing part of the first connecting part and the third connecting part by bolts. The third connecting part and the first connecting part are both C-shaped bend structures, and a primary snap-lock is formed between the side plate and the base plate; then the fixing plate is used to reinforce the fixing part and the third connecting part with bolts, providing double locking to ensure that the shell will not loosen even under strong vibration or heavy load.

[0010] Preferably, the other side of the first side panel is provided with a first mounting part in a C-shaped bend. The first mounting part is rotatably connected to a baffle for protecting the internal roller shutter component of the box. The baffle is provided with a second mounting part in a C-shaped bend. The second mounting part can be inserted or removed along the axis of the first mounting part, so that the baffle and the first side panel form a detachable connection. The first mounting part is pivotally connected to the baffle, which can realize the arbitrary opening and closing of the baffle to meet the user's cleaning needs for the tailgate. The second mounting part on the baffle can be quickly inserted or removed along the axis of the first mounting part, and the baffle can be disassembled or replaced without tools, which facilitates daily cleaning, maintenance and quick replacement of damaged parts.

[0011] Furthermore, the openings of the first and second mounting portions are positioned opposite each other, and the inner diameter of the first mounting portion is the same as the outer diameter of the second mounting portion. The opposite openings of the first and second mounting portions, along with their identical radial dimensions, enable precise concentric fitting, ensuring low rotational resistance and smooth operation when the baffle rotates around its axis. The matching inner and outer diameters allow the second mounting portion to automatically align with the first mounting portion upon insertion, enabling rapid installation without fine-tuning, further simplifying the assembly process and improving efficiency. The same-diameter fit increases the contact surface, resulting in more even and robust support at the pivot point, effectively reducing swaying and lateral movement, and ensuring the baffle does not loosen or rub during bumpy driving.

[0012] Furthermore, in the closed state, the baffle abuts against the first mounting part through its inner wall to form a limiting position. When the baffle is in the closed state, its inner wall abuts tightly against the first mounting part, automatically forming a limiting position, which can effectively prevent the baffle from rotating excessively or deviating from the predetermined position, ensuring that each closure is accurate and in place.

[0013] Preferably, the roller blind assembly comprises several roller blind slats, each slat including a first insertion portion and a second insertion portion on both sides. The first insertion portion can be inserted into or withdrawn along the axis of the second insertion portion, forming a detachable connection between adjacent roller blind slats. This allows individual roller blind slats to be disassembled and replaced independently when damaged, eliminating the need to replace the entire roller blind assembly, significantly reducing maintenance costs and time. Furthermore, compared to traditional threaded or hinged connections, it offers stronger sealing, is less prone to water ingress, and maintains an undisturbed internal environment.

[0014] Furthermore, both the first and second insertion parts are C-shaped, with the second insertion part completely covering the opening of the first insertion part. The second insertion part effectively covers the first insertion part from the outside, with its opening facing opposite directions, preventing the first insertion part from accidentally detaching under vibration, tension, or rolling impact, thus enhancing the structural stability of the overall roller shutter assembly. The complete coverage of the first insertion part by the second insertion part, especially by concealing its opening, significantly reduces the entry of dust, moisture, and other impurities into the interior through the connection gaps, thereby improving the protective performance of the roller shutter slats in harsh environments. The double C-shaped structure, after assembly, fits tightly with almost no visible gaps at the joints, resulting in good overall visual consistency. The fixed and clear insertion direction enables efficient and rapid positioning, improving assembly efficiency and reducing error rates.

[0015] The beneficial effects of this utility model are as follows: The base plate no longer relies on traditional bolts to connect with the first and second side plates. Instead, a snap-fit ​​or plug-in detachable connection is achieved through pre-set first and second connecting parts, further reinforced by a fixing plate. After the overall shell is formed, all seams fit tightly, effectively preventing rainwater and dust from seeping in and avoiding water accumulation inside the shell. Excellent sealing performance prevents rainwater or moisture from entering the shell, effectively protecting the internal roller shutter components from moisture corrosion, preventing rust, ensuring smooth opening and closing of the roller shutter, and extending the overall service life of the machine. The detachable connection structure allows for faster installation and disassembly of the entire shell, eliminating the need for special tools and cumbersome bolt work, thus greatly reducing maintenance difficulty and costs. Compared with traditional bolt fixing, the use of standardized connectors and fixing plates not only simplifies the types of parts but also facilitates large-scale production and assembly, reducing the overall manufacturing and subsequent maintenance costs.

[0021] like Figure 1-4The illustration shows an embodiment of a car trunk cover according to the present invention, comprising a trunk shell 1 and a roller shutter component disposed inside the trunk shell 1. The trunk shell 1 includes a bottom plate 11, on both sides of which are provided first connecting portions 111. The bottom plate 11 is detachably connected to a first side plate 12 and a second side plate 13 via the first connecting portions 111. The first side plate 12 and the second side plate 13 are provided with second connecting portions 121 for detachable connection with the first connecting portions 111. After the bottom plate 11, the first side plate 12, and the second side plate 13 are connected, they are fixedly connected by a fixing plate 2 to form the overall shape of the trunk shell 1. The bottom plate 11 is no longer connected to the first side plate 12 and the second side plate 13 by traditional bolts, but instead achieves a snap-fit ​​or plug-in detachable connection through the preset first connecting portions 111 and the second connecting portions 121, and is then reinforced by the fixing plate 2. After the integral housing 1 is formed, all seams fit tightly, effectively preventing rainwater and dust from seeping in and avoiding water accumulation inside the housing 1. Excellent sealing performance prevents rainwater or moisture from entering the interior of the housing 1, effectively protecting the internal roller shutter components from moisture corrosion, preventing rust, ensuring smooth opening and closing of the roller shutter, and extending the overall service life of the machine. The detachable connection structure makes the installation and disassembly of the entire housing 1 much faster, requiring no special tools or cumbersome bolt work, allowing for easy assembly, disassembly, and routine maintenance, greatly reducing maintenance difficulty and cost. Compared with traditional bolt fixing, the use of standardized connectors and fixing plates 2 not only simplifies the types of parts but also facilitates large-scale production and assembly, reducing the overall manufacturing and subsequent maintenance costs.

[0022] The first connecting part 111 includes a supporting part 112 and a fixing part 113 located on the side of the supporting part 112. The fixing part 113 is C-shaped. The second connecting part 121 is an opening groove that matches the shape of the first connecting part 111. The first connecting part 111 can be inserted into or removed through the opening of the second connecting part 121. The C-shaped fixing part 113 and the opening groove fit precisely together to form a self-locking structure similar to a buckle. Under the bumps and impacts generated during vehicle operation, the two are tightly engaged and not easy to loosen or slip, which greatly improves the connection reliability and vibration resistance. The first connecting part 111 can be directly inserted into or removed through the opening of the second connecting part 121 without additional tools or complex adjustments, which can complete the quick installation and disassembly of the side plate and the bottom plate 11, shortening the assembly cycle and making maintenance more convenient.

[0023] The second connecting part 121 has an L-shaped limiting part 122 on one side of its opening. One end of the limiting part 122 is fitted into the connection between the supporting part 112 and the fixing part 113, forming a limiting connection that stops the fixing part 113. The L-shaped limiting part 122, fitted into the connection between the supporting part 112 and the fixing part 113, forms a reliable stopping structure. During insertion, the limiting part 122 and the fixing part 113 mesh with each other, accurately limiting the insertion depth and position of the side plate, preventing misalignment or loosening due to vibration or operational deviation. The limiting part 122 forms a secondary physical barrier against the fixing part 113, effectively preventing the fixing part 113 from being accidentally pulled out along the insertion direction even under strong bumps or impacts, further enhancing its self-locking performance and anti-detachment capability.

[0024] The support portion 112 and the base plate 11 form an L-shape. The other side of the opening of the second connecting portion 121 abuts against the base plate 11 in a first direction. The end faces of the support portion 112 and the fixing portion 113 abut against the inner wall of the first connecting portion 111, with their abutment directions parallel to the first direction. The L-shaped structure of the support portion 112 and the base plate 11 allows the connector to fit against the base plate 11 in both vertical and parallel directions. The other side of the opening of the second connecting portion 121 abuts against the base plate 11, and the parallel abutment between the end faces of the support portion 112 and the fixing portion 113 and the inner wall of the first connecting portion 111 together form a multi-faceted support, significantly improving the local structural rigidity and overall load-bearing capacity of the shell 1. The abutment surfaces are perpendicular or parallel to each other, not only fitting tightly but also sealing each other in multiple directions, further reducing the infiltration paths of rainwater and dust, and making the sealing effect more reliable.

[0025] The base plate 11, the first side plate 12, and the second side plate 13 are provided with a third connecting part 114, which is C-shaped. The fixing plate 2 is bolted to the fixing part 113 of the first connecting part 111 and the third connecting part 114. The third connecting part 114 and the first connecting part 111 are both C-shaped, forming a primary snap-lock between the side plate and the base plate 11. The fixing plate 2 then reinforces the fixing part 113 and the third connecting part 114 with bolts, providing double locking to ensure that the shell 1 will not loosen even under strong vibration or heavy load.

[0026] In this embodiment, unlike the previous embodiment, a first mounting portion 123 with a C-shaped bend is provided on the other side of the first side plate 12. The first mounting portion 123 is rotatably connected to a baffle 3 for protecting the internal roller shutter component of the box shell 1. The baffle 3 has a second mounting portion 31 with a C-shaped bend. The second mounting portion 31 can be inserted into or removed along the axis of the first mounting portion 123, allowing the baffle 3 and the first side plate 12 to form a detachable connection. The first mounting portion 123 is pivotally connected to the baffle 3, enabling arbitrary opening and closing of the baffle 3 to meet the user's cleaning needs for the tailgate cover. The second mounting portion 31 on the baffle 3 can be quickly inserted into or removed along its axis from the first mounting portion 123, allowing for tool-free disassembly or replacement of the baffle 3, facilitating daily cleaning, maintenance, and rapid replacement of damaged parts.

[0027] The openings of the first mounting portion 123 and the second mounting portion 31 are arranged opposite to each other, and the inner diameter of the first mounting portion 123 is the same as the outer diameter of the second mounting portion 31. The openings of the first mounting portion 123 and the second mounting portion 31 are opposite and have the same radial dimension, enabling precise concentric fit and ensuring low rotational resistance and smooth operation when the baffle 3 rotates around its axis. The matching inner and outer diameters allow the second mounting portion 31 to automatically align with the first mounting portion 123 upon insertion, allowing for rapid installation without fine-tuning, further simplifying the assembly process and improving assembly efficiency. The same diameter fit increases the contact surface, resulting in more even and robust support at the pivot point, effectively reducing torsional sway and lateral shaking, ensuring that the baffle 3 does not loosen or rub during bumpy driving.

[0028] When the baffle 3 is in the closed state, its inner wall abuts against the first mounting part 123 to form a limit. When the baffle 3 is in the closed state, its inner wall abuts tightly against the first mounting part 123, automatically forming a limit, which can effectively prevent the baffle 3 from rotating excessively or deviating from the predetermined position, ensuring that each closure is accurate.

[0029] In the embodiments of this application, unlike the embodiments described above, the roller blind component is composed of a plurality of roller blind slats 10. Each roller blind slat 10 includes a first insertion portion 101 and a second insertion portion 102 located on both sides. The first insertion portion 101 can be inserted into or withdrawn along the axis of the second insertion portion 102, thereby forming a detachable connection between adjacent roller blind slats 10. This allows for independent disassembly and replacement of a single roller blind slat 10 after damage, eliminating the need to replace the entire roller blind component, significantly reducing maintenance costs and time. Furthermore, compared to traditional threaded or hinged connections, it offers stronger sealing, is less prone to water ingress, and maintains an undisturbed internal environment.

[0030] Furthermore, both the first insertion portion 101 and the second insertion portion 102 are C-shaped, with the second insertion portion 102 completely covering the opening of the first insertion portion 101. The second insertion portion 102 effectively covers the first insertion portion 101 from the outside, with its opening facing opposite directions, preventing the first insertion portion 101 from accidentally detaching under vibration, tension, or rolling impact, thus enhancing the structural stability of the overall roller shutter slat 10 assembly. The complete coverage of the first insertion portion 101 by the second insertion portion 102, especially by concealing its opening, significantly reduces the entry of dust, moisture, and other impurities into the interior through the connection gaps, thereby improving the protective performance of the roller shutter slat 10 in harsh environments. The double C-shaped structure, after assembly, fits tightly with almost no visible gaps at the connection points, resulting in good overall visual consistency. Furthermore, the insertion direction is fixed and clear, enabling efficient and rapid positioning, improving assembly efficiency, and reducing the error rate.

[0031] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
