Technical Field
[0001] This utility model relates to the field of vehicle camping sunshade roller blinds installed on vehicles, and in particular to the main structure scheme of vehicle camping sunshade roller blinds. Background Technology
[0002] Currently, vehicle-mounted awnings are camping sunshade components installed on the roof of cars, and are widely popular among car travel enthusiasts due to their portability and ease of storage. When in use, the awning's sunshade curtain can be pulled out and opened to one side of the vehicle to provide sun and rain protection, meeting the needs of outdoor camping. For details on the usage and operation of such products, those skilled in the art can refer to Chinese patent document CN221476635U.
[0003] Among existing vehicle sunshade products, there is a published Chinese patent document with patent application number CN202421326305.7, publication number CN222372648U, entitled "A Clutch-operated Silent Car Sunshade." The car sunshade solution described in this document mainly consists of a sunshade roll-up box, a roll-up shaft, a sunshade, a lower support strip, and a pair of folding support rods. The folding support rods connect the sunshade roll-up box and the lower support strip, providing support for the unfolded sunshade. The weight and wind resistance of the unfolded sunshade and the folding support rods are directly borne by the sunshade roll-up box. Therefore, to ensure sufficient structural strength of the sunshade roll-up box and prevent deformation and breakage, the most direct approach is to make the overall wall thickness of the sunshade roll-up box thicker, thereby increasing its resistance to deformation and tearing. However, this significantly increases the weight and volume of the entire car sunshade. When such sunshades are installed on the roof of SUVs, MPVs, and sedans, the following problems arise: First, the excessive size and weight of the sunshade increases the load on the vehicle roof, placing higher demands on the structural strength of the roof and limiting its application. Second, the excessive size and weight of the sunshade, once installed on the roof, affects the vehicle's center of gravity, potentially causing the vehicle to veer off course and compromising safety at high speeds. Third, the excessive size and weight of the sunshade increases the vehicle's weight, leading to increased energy consumption. Therefore, given the aforementioned shortcomings of existing car sunshades, the applicant believes it is essential to optimize the structure of these products to better meet user needs. Utility Model Content
[0004] The purpose of this utility model is to solve the above-mentioned problems and shortcomings, and to provide an improved main structure for a vehicle camping sunshade roller blind. This improved main structure, through a scientifically and rationally designed structure and mechanical distribution, utilizes the inner cavity and metal reinforcing strips to effectively strengthen the installation and stress-bearing parts. When the main shell is installed on a vehicle, the key supporting and stress-bearing parts are not weakened but effectively strengthened, effectively ensuring the service life, installation stability, and safety of the entire sunshade roller blind. This allows the entire main shell to be made thinner, lighter, and more compact, effectively reducing the overall weight of the sunshade roller blind product and making it suitable for more vehicles, regardless of model, with a wide range of applications.
[0005] The technical solution of this utility model is achieved as follows: an improved main structure for a vehicle camping sunshade roller blind, characterized by including a main shell integrally formed along its length, the main shell consisting of an arched upper shell with an arc-shaped inner cavity, a lower half with an inner cavity, and a bottom support plate extending and connected to the bottom edge of the lower half, and an open opening arranged along its length is formed on one side between the bottom support plate and the arched upper shell; a mounting groove is provided on the back side between the arched upper shell and the lower half, and a mounting groove is also provided at the bottom of the lower half; a metal reinforcing strip is inserted and fitted into the inner cavity.
[0006] Preferably, the inner side of the lower half is further provided with an opening groove that communicates with the inner cavity.
[0007] Preferably, the outer edge of the opening groove is further provided with reinforcing ribs to increase the load-bearing capacity of the inner cavity.
[0008] Preferably, the inner side of the lower half connected to the base plate is also provided with a groove to enhance structural strength and facilitate screwing.
[0009] Preferably, the outer back of the arched upper shell is provided with an integrally formed rib arranged along its length, and the rib is also provided with a groove for easy screwing.
[0010] Preferably, the inner side of the arc-shaped cavity is further provided with a groove along its length to enhance structural strength and facilitate screwing.
[0011] Preferably, a supporting step is provided on the inner side between the arched upper shell and the lower shell.
[0012] The beneficial effects of this utility model are as follows: By inserting a metal reinforcing strip into the inner cavity of the lower half, the folding support rod of the sunshade roller blind product can be hinged to the metal reinforcing strip. This ensures that even with reductions in the wall thickness of the arched upper and lower shells, the folding support rods maintain high and reliable support strength, preventing deformation of the main shell and significantly extending its service life. Furthermore, this structural design allows for thinner walls in the arched upper and lower shells, reducing the overall weight of the main shell and effectively lowering the weight of the entire sunshade roller blind product. This reduces fuel consumption and avoids increased operating costs. Simultaneously, reducing the overall weight of the sunshade roller blind product also prevents the vehicle's center of gravity from tilting to one side, significantly minimizing the impact on vehicle stability and safety. This makes it suitable for a wider range of vehicles, regardless of model, and has a broad application range. In addition, by placing the mounting slot in the lower half and utilizing the metal reinforcing strip, the structural strength and deformation resistance of the mounting slot are effectively improved, ensuring smooth installation and removal of the main shell on the vehicle. The curved inner cavity provides installation space for the roller blind's winding shaft and the blind itself. The base plate provides a storage platform for other detachable accessories. The open opening facilitates the entry and exit of the blind and its folding support rods, allowing the blind to extend, unfold, and retract. Attached Figure Description

[0022] like Figure 3 As shown, the improved main structure of the vehicle camping sunshade roller blind of this utility model includes a main shell 1 integrally formed along its length. The main shell 1 is composed of an arched upper shell 11 with an arc-shaped inner cavity 10, a lower half 12 with an inner cavity 13, and a bottom support plate 14 extending and connected to the bottom edge of the lower half 12. An open opening 20 arranged along its length is also formed on one side between the bottom support plate 14 and the arched upper shell 11. A mounting groove 15 is also provided on the back side between the arched upper shell 11 and the lower half 12, and a mounting groove 15 is also provided at the bottom of the lower half 12. Figure 1 and Figure 2 As shown, a metal reinforcing strip 2 is inserted and fitted into the inner cavity 13. Specifically, the wall thickness of the metal reinforcing strip 2 is greater than the wall thickness of the main housing 1. More specifically, the wall thickness of the metal reinforcing strip 2 is more than twice the wall thickness of the main housing 1.
[0023] In practical applications, one end of the folding support rod 4 of the sunshade roller blind product can be screwed through the folding support rod and the lower half 12 in sequence before being locked into the metal reinforcing strip 2. Preferably, as... Figure 1 As shown, the lower half 12 has notches 121 at both ends on its inner side, which expose the ends of the metal reinforcing strip 2. This allows the screws to be directly locked onto the metal reinforcing strip 2 after passing through the folding support rod 4 of the sunshade roller blind, making assembly easier and further reducing the overall weight of the main housing 1.
[0024] To facilitate the installation of other detachable accessories of the sunshade roller blind product onto the metal reinforcing strip 2, such as... Figure 3 As shown, the lower half 12 also has an opening slot 131 that communicates with the inner cavity 13. During fixed installation, other detachable accessories can pass through the opening slot 131 and be fixed to the metal reinforcing strip 2 in the inner cavity 13. In practical applications, such as... Figure 1 As shown, the metal reinforcing strip 2 located at the opening slot 131 also has several screw holes 21 arranged along its length on one side. This facilitates the secure installation of other detachable accessories onto the metal reinforcing strip 2.
[0025] like Figure 3As shown, the outer edge of the opening slot 131 is also provided with reinforcing ribs 132 to increase the load-bearing capacity of the inner cavity 13. This improves the structural strength of the outer edge of the opening slot 131, preventing deformation and damage to the opening slot 131 after the installation of other detachable accessories, thereby increasing the load-bearing capacity of the inner cavity 13. This prevents the space of the inner cavity 13 from being expanded, ensuring that the metal reinforcing strip 2 can be tightly and securely inserted into the inner cavity 13, thus guaranteeing the reliability of use.
[0026] like Figure 3 As shown, the inner side of the lower half 12 connected to the bottom support plate 14 is also provided with a groove 16 to enhance structural strength and facilitate screw installation. This allows the end cap 3 of the sunshade roller blind product to be easily attached to the end of the main housing 1 using mating screws 31.
[0027] Because the arched upper shell 11 is an arched structure, it is prone to bending and deformation. To improve the structural strength of the arched upper shell 11, such as... Figure 3 As shown, the outer back of the arched upper shell 11 is also provided with an integrally formed rib 17 arranged along its length, and the rib 17 is also provided with a groove 16 for easy screwing. By providing the rib 17, the structural strength of the arched upper shell 11 can be improved. By providing the groove 16, the end cap 3 of the sunshade roller blind product can be more firmly connected to the end of the main shell 1 with the screw 31.
[0028] like Figure 3 As shown, the inner side of the arc-shaped inner cavity 10 is also provided with a groove 16 arranged along its length to enhance structural strength and facilitate screw installation. By providing the groove 16 here, the end cap 3 of the sunshade roller blind product can be more securely connected to the end of the main housing 1 with the screw 31. Meanwhile, as... Figure 3 and Figure 7 As shown, by setting the wire grooves 16 in the above three parts respectively, and locking the end cap 3 into the corresponding wire grooves 16 with three screws 31, it can also play a stable triangular support role for the main housing 1. In this way, even if the open opening 20 is set on the main housing 1, the main housing 1 as a whole has very reliable load-bearing performance and very high structural strength, so as to further prevent the deformation of the main housing 1 and improve the service life of the main housing 1.
[0029] like Figure 1 and Figure 8 As shown, a support step 18 is also provided on the inner side between the arched upper shell 11 and the lower shell 12. This allows the folding support rod 4 of the sunshade roller blind product to be folded and placed stably on the support step 18, preventing the folding support rod 4 from swaying when the vehicle is traveling on bumpy roads.
[0030] When assembling the main housing 1, metal reinforcing strip 2, and other components of the sunshade roller blind product into a complete sunshade roller blind product, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, other components of the sunshade roller blind product include a front cover 5, a sunshade curtain 6, a winding roller 7, a drive motor 8 with a reduction function, two folding support rods 4, and two end caps 3. The metal reinforcing strip 2 is inserted into the inner cavity 13 of the main housing 1. The two end caps 3 are each equipped with screws 31, and are respectively fixed to both ends of the main housing 1 by the screws 31. The drive motor 8 is located at one end inside the main housing 1. The winding roller 7 is rotatably disposed in the arc-shaped inner cavity 10, and one end of the winding roller 7 is connected to the drive motor. The power output end of the motor 8 is fixedly connected, and the other end of the take-up roller 7 is hinged to the end cap 3 away from the drive motor 8. One end of the two folding support rods 4 is hinged to a fixed seat 41. A locking screw 42 is inserted on the fixed seat 41. The fixed seat 41 is locked to the metal reinforcing strip 2 by the locking screw 42. The front cover 5 is hinged to the other end of the two folding support rods 4 respectively, and the front cover 5 can cover the open opening 20 of the main housing 1. The sunshade 6 is wound around the take-up roller 7, and the outer end of the sunshade 6 is fixed to the front cover 5. After the complete sunshade roller blind is installed on the roof, the front cover 5 is arranged at a downward angle. When unfolded, the drive motor 8 drives the winding roller 7 to rotate, so as to loosen the tension on the sunshade curtain 6. Under the action of gravity, the front cover 5 separates from the open opening 20 and pulls the sunshade curtain 6 and the two folding support rods 4 to extend, so that the sunshade roller blind can be unfolded and play the role of sunshade and rain protection. When storing, simply reverse the movement.
[0031] In practical applications, such as Figure 4 As shown, the mounting groove 15 has a groove structure with a wide bottom and a narrow opening. When installed on the roof of a vehicle, this utility model also includes a roof mounting bracket 9, which includes a first L-shaped fixing member 91 and a second L-shaped fixing member 92. The first L-shaped fixing member 91 and the second L-shaped fixing member 92 are respectively composed of an integrally formed vertical plate and a horizontal plate. The vertical plate and the horizontal plate of the first L-shaped fixing member 91 are respectively provided with clamping blocks 93. Tightening screws 94 are also provided between the clamping blocks 93 and the vertical plate, and between the clamping blocks 93 and the horizontal plate. The vertical plate of the second L-shaped fixing member 92 is fixed together with the vertical plate of the first L-shaped fixing member 91 by welding or screw locking. During installation, the two clamping blocks 93 are slidably embedded into the mounting groove 15, and then the tightening screws 94 are turned to clamp the corresponding mounting groove 15 openings of the clamping blocks 93 and the vertical plate, and the clamping blocks 93 and the horizontal plate, respectively. Then, the horizontal plate of the second L-shaped fixing member 92 is fixed to the roof of the car to complete the installation.
[0032] In practical applications, other components of the sunshade roller blind product include two telescopic support rods 100. For example... Figure 6 and Figure 9 As shown, when stored, the two telescopic support rods 100 are placed on the base plate 14. When the sunshade 6 is unfolded, the two telescopic support rods 100 are fixed at both ends of the bottom of the front cover 5 to support the front cover 5, so that the stress point is not concentrated at the hinge of the folding support rod 4 and the metal reinforcing strip 2, preventing the hinge from deforming or breaking or the sunshade 6 from collapsing, thereby improving the reliability of use.
