Technical Field
[0001] This application relates to the field of automotive accessories, and more particularly to a roof box. Background Technology
[0002] In recent years, with the development of the global automotive industry and the continuous increase in the number of cars purchased, people have begun to put forward new requirements for the functions of cars themselves. For example, in order to meet the needs of off-road performance and space utilization, a streamlined closed luggage compartment is usually installed on the roof of the vehicle. The bottom of the compartment is fixed to the roof and has an openable lid, which makes it easy to put clothes, food or other outdoor supplies inside, solving the problem of limited interior space and improving the outdoor travel experience.
[0003] However, currently, the lids of suitcases are generally made of ABS or other plastics, which makes the lids prone to aging and the surface of the lids is not very attractive. Utility Model Content
[0004] The purpose of this application is to provide a roof box that is not easily aged and has an aesthetically pleasing surface.
[0005] This application discloses a roof box, which includes a lid, a bottom, and a support assembly. The bottom is for mounting on the roof of a vehicle. The tail ends of the lid and the bottom are hinged together. One end of the support assembly is connected to the lid, and the other end is connected to the bottom. The outer layer of the lid is made of carbon fiber cloth, and the joints between adjacent carbon fiber cloths are located at corners of the lid.
[0006] Optionally, the roof cover includes a top, a side, and an extension. When the roof box is folded down, the top of the cover is positioned opposite the bottom of the box, and the side and the extension surround the top of the cover. One end of the side is connected to the edge of the top of the cover, and the other end is connected to the extension. The surrounding range of the extension is greater than that of the side. When the roof box is folded down, the inner side of the extension is opposite to the side of the bottom of the box.

The crossbars, the long frame strips, and the short frame strips are made of carbon fiber material.
[0015] The beneficial effects of this application embodiment are as follows: Compared with the current solution where the roof cover of the vehicle is made entirely of plastic material, the roof cover of the vehicle in this application is mainly made of carbon fiber material, and the outer layer of the cover is spliced with carbon fiber cloth. Due to the material properties of carbon fiber itself, it is not easily affected by weather conditions such as high temperature, sun exposure, and low temperature, thus ensuring the service life of the cover and preventing aging. Moreover, the splicing point of the adjacent carbon fiber cloth is located at the corner of the cover. Since the corner of the roof is not easy to observe, setting the splicing point of the carbon fiber cloth at the corner is not easy to be observed even without concealment, and will not affect the aesthetics of the product.

Detailed Implementation
[0023] It should be understood that the terminology, specific structural and functional details used herein are merely for describing particular embodiments and are representative. However, this application may be implemented in many alternative forms and should not be construed as being limited to the embodiments set forth herein.
[0024] Furthermore, unless otherwise explicitly specified and limited, "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0025] like Figure 1 and Figure 2 As shown in the illustration, this application provides a roof box 10, which includes a lid 100, a bottom 200, and a support assembly 300. The bottom 200 is used to mount on the roof of a vehicle, and the rear end of the lid 100 and the rear end of the bottom 200 are hinged together. It should be noted that the front end of the lid 100 is the openable end, and the rear end of the lid 100 is located at opposite ends of the front end.
[0026] One end of the support component 300 is connected to the lid 100, and the other end of the support component 300 is connected to the bottom of the box 200. Specifically, the support component 300 can be two air springs, which are located on both sides of the roof luggage box 10. The two ends of the air springs are connected to the lid 100 and the bottom of the box 200 respectively to support the lid 100 and facilitate the folding and unfolding of the lid 100.
[0027] The main body of the box cover 100 is made of carbon fiber material, and its outer layer is made of carbon fiber cloth spliced together. The splicing point of the adjacent carbon fiber cloth is located at the corner position of the box cover 100. The "corner position of the box cover 100" refers to the position of the box cover 100 surface with a large curvature, specifically a position greater than 90 degrees.
[0028] Compared to the current roof box 10 where the lid 100 is entirely made of plastic, the roof box 10 in this application is primarily made of carbon fiber, and the outer layer of the lid 100 is made of carbon fiber cloth. Due to the inherent properties of carbon fiber, it is not easily affected by high temperatures, direct sunlight, or low temperatures, thus ensuring the lifespan of the lid 100 and preventing aging. Furthermore, the joints of the adjacent carbon fiber cloths are located at the corners of the lid 100. Since the corners of the roof are not easily observed, placing the joints of the carbon fiber cloths at the corners makes them difficult to see even without concealment, thus not affecting the aesthetics of the product.
[0029] Moreover, in this embodiment, the surface of the carbon fiber cloth can have plain weave, twill weave, satin weave, and other textures. After the splicing of different carbon fiber cloths is made at the corner of the box cover 100, the connection of the textures on the different carbon fiber cloths is not abrupt, making the surface of the box cover 100 look neat and more aesthetically pleasing.
[0030] like Figure 3 and Figure 4 As shown, the roof cover 100 includes a top cover 130, a side cover 140, and an extension 150. The top cover 130 is arc-shaped. When the roof luggage compartment 10 is folded down, the top cover 130 is positioned opposite to the bottom cover 200. The side cover 140 and the extension 150 surround the top cover 130. One end of the side cover 140 is connected to the edge of the top cover 130, and the other end of the side cover 140 is connected to the extension 150. The angle between the side cover 140 and the roof cover fabric is an obtuse angle, and the angle between the extension 150 and the roof cover fabric is also an obtuse angle.
[0031] The outer extension 150 has a larger circumferential range than the cover side 140, meaning the outer extension 150 extends further outward from the cover side 140. When the roof box 10 is folded, the inner side of the outer extension 150 faces the side of the bottom 200, facilitating locking and connection with the bottom 200 after the lid 100 is folded. Furthermore, the outer extension 150 has partially outward-expanding handles 151 distributed at the front end and left and right sides of the lid 100, facilitating lifting the lid 100 when unfolding the roof box 10.
[0032] Specifically, the outer layer of the lid 100 includes a top carbon fiber cloth 111, a side carbon fiber cloth 112, and an outer carbon fiber cloth 113. The top carbon fiber cloth 111 is located at the top 130 of the lid, the side carbon fiber cloth 112 is located at the side 140 of the lid, and the outer carbon fiber cloth 113 is located at the outer extension 150. The joint between the top carbon fiber cloth 111 and the side carbon fiber cloth 112 is located at the junction of the top 130 of the lid and the side 140 of the lid, and the joint between the side carbon fiber cloth 112 and the outer carbon fiber cloth 113 is located at the junction of the side 140 of the lid and the outer extension 150.
[0033] Because the top curvature of the lid 100 is small, and the curvature of each side and each side extension is also small, the outer layer of the lid 100 is made of top carbon fiber cloth 111, side carbon fiber cloth 112 and outer carbon fiber cloth 113 spliced together. The top and sides of the lid 100 are respectively bonded with different carbon fiber cloths. Because the curvature of the bonding surface of the carbon fiber cloth is small, the problem of wrinkling of the carbon fiber cloth is avoided.
[0034] Furthermore, the junction between the top 130 and the side 140 of the cover is rounded, and the junction between the side 140 and the outer extension 150 is also rounded. Because the rounded corners are curved, the edges of the carbon fiber fabric are less prone to warping at the rounded corners. After the top carbon fiber fabric 111 and the side carbon fiber fabric 112 are spliced together, they fit more tightly, making the seam more concealed and less likely to be observed.
[0035] Furthermore, the cover side portion 140 includes a front side portion 141, a rear side portion 142, a left side portion 143, and a right side portion 144. The side carbon fiber cloth 112 includes a front carbon fiber cloth 114, a rear carbon fiber cloth 115, a left carbon fiber cloth 116, and a right carbon fiber cloth 117. The front carbon fiber cloth 114 is disposed on the front side portion 141, the rear carbon fiber cloth 115 is disposed on the rear side portion 142, the left carbon fiber cloth 116 is disposed on the left side portion 143, and the right carbon fiber cloth 117 is disposed on the right side portion 144.
[0036] Correspondingly, the splicing point of the front carbon fiber cloth 114 and the left carbon fiber cloth 116 is located at the junction of the front part 141 and the left part 143; the splicing point of the front carbon fiber cloth 114 and the right carbon fiber cloth 117 is located at the junction of the front part 141 and the right part 144; the splicing point of the rear carbon fiber cloth 115 and the left carbon fiber cloth 116 is located at the junction of the rear part 142 and the left part 143; and the splicing point of the rear carbon fiber cloth 115 and the right carbon fiber cloth 117 is located at the junction of the rear part 142 and the right part 144.
[0037] Since each side of the lid 100 is curved, the above design makes the carbon fiber cloth on each side of the lid 100 surface independent, avoiding wrinkles in the carbon fiber cloth at the corners, and making the seams more concealed at the corners and less likely to be observed.
[0038] In this embodiment of the application, the outer layer of the box cover 100 is polished, that is, the surface of the carbon fiber cloth is also polished, making the surface of the box cover 100 more glossy. Under the illumination of light, the surface of the box cover 100 will have a mirror-like reflective effect. In particular, the corners of the box cover 100 will reflect light from multiple angles, which will easily produce gloss, making the seams at the corners less likely to be observed.
[0039] In this embodiment of the application, the box cover 100 is made of multiple layers of carbon fiber cloth stacked together to improve the overall strength of the box cover 100; in order to ensure the strength of the box cover, the box cover 100 is formed by stacking 5-8 layers of carbon fiber cloth.
[0040] The outermost layer of carbon fiber cloth is divided into multiple independent sections, which are placed on the top, sides, and outer edge of the lid 100. However, for the inner carbon fiber cloth, each layer can be laid as a whole or also divided into multiple sections and attached together, with the edges of adjacent carbon fiber cloths in the same layer stacked. In addition, glass fiber is also placed between the stacked carbon fiber cloths. The glass fiber is distributed in strips between the upper and lower layers of carbon fiber cloth to improve the strength of the carbon fiber cloth at the joints, thereby improving the strength of the lid 100.
[0041] like Figure 5 As shown, the bottom of the box 200 includes a frame 210, a plurality of crossbars 220, and at least two fixing strips 230. The frame 210 includes two long frame strips 211 and two short frame strips 212, with the two long frame strips 211 and the two short frame strips 212 arranged opposite each other. The plurality of crossbars 220 are arranged side by side, and the two ends of each crossbar 220 are respectively connected to the two short frame strips 212. At least two fixing strips 230 are arranged side by side on the side of the crossbars 220 away from the box cover 100 for fixing to the top of the car. The crossbars 220, the long frame strips 211, and the short frame strips 212 are made of carbon fiber material.
[0042] The above design reduces the weight of the bottom 200, making it easier to move and install the roof box 10. Of course, in other embodiments, the frame 210 and crossbar 220 can also be made of aluminum alloy or other materials.
[0043] like Figure 5As shown, the roof box 10 also includes a U-shaped support frame 400. Both ends of the U-shaped support frame 400 are hinged to the front end of the box bottom 200, so that the U-shaped support frame 400 can rotate around the front end of the box bottom 200, which facilitates the folding of the U-shaped support frame 400 and avoids folding the U-shaped support frame 400 when disassembling and installing the roof box 10.
[0044] The roof box 10 has a cushioning pad and fabric inside. The fabric is arranged between the lid 100 and the bottom 200 and is supported by a U-shaped support frame 400 to increase the height of the front end of the fabric, making it easier for users to put items into the roof box 10.
[0045] The above description, in conjunction with specific optional embodiments, provides a further detailed explanation of this application and should not be construed as limiting the specific implementation of this application to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of this application, and all such modifications or substitutions should be considered within the scope of protection of this application.
