Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts, and in particular to an easy-to-install and remove automotive sunshade. Background Technology

[0002] With the increasing popularity of automobiles, sunshades, as devices that protect the interior environment and reduce the impact of direct sunlight, have gradually become an important choice for car owners. However, existing car sunshades have significant limitations in practical applications, especially in terms of installation compatibility. Due to differences in door structures and dimensions among different car models, traditional sunshades usually require custom design for specific models, resulting in poor versatility. Consumers often need to purchase new sunshades when changing vehicles or dealing with different car models, which not only increases usage costs but also wastes resources. In addition, the installation methods of existing sunshades are usually quite complex, and users may face inconvenience during installation and removal, further reducing the product's practicality and user experience. Therefore, designing a car sunshade that can adapt to multiple car models, is easy to install and remove quickly, and has a flexible structure has become an urgent technical challenge to be solved. Utility Model Content

[0003] The purpose of this invention is to provide an easy-to-install and disassemble car sunshade to overcome the shortcomings of the existing technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] Easy-to-install and remove car sunshade. The sunshade features a detachable door mounting base and sealing block structure, adaptable to different types of car doors, improving versatility and ease of installation.

[0006] This utility model provides an easy-to-assemble and disassemble car sunshade, including a storage base, a sunshade net and positioning crossbars, a sealing block and a door mounting base. Among them:

[0007] The storage base is the main outer shell of the sunshade, containing a freely rotating roller and a torsion spring shaft. The torsion spring shaft is inserted into the roller and connected to a sealing block fixed at one end of the storage base. The sealing block and the storage base are detachably connected, specifically by a positioning protrusion on the sealing block engaging with a groove in the end shell of the storage base for positioning, and then secured with bolts. A sunshade net is fixedly mounted on the roller, which winds around and is stored in the storage base as the roller rotates. A long slot is provided on one side of the storage base for the sunshade net to extend out.

[0008] Furthermore, one end of the sunshade net is fixed to the roller blind roller, and the other end is fixedly provided with a positioning crossbar. The positioning crossbar is used to extend and flatten the sunshade net, preventing wrinkles or loosening during use. A fastener is connected to the middle of the positioning crossbar via a pivot. The design shape of the fastener matches the pre-fixed hooks on the top of the door, and the sunshade net is fixed by the engagement of the fastener and the hooks.

[0009] Specifically, the sealing block has an inwardly recessed mounting groove, and an inwardly extending positioning protrusion is provided along the edge of the mounting groove. The design of the mounting groove and positioning protrusion allows the door mounting seat to be quickly and accurately installed at both ends of the storage seat. The depth and width of the mounting groove precisely match the dimensions of the corresponding parts of the door mounting seat, ensuring that misalignment does not occur during installation. The number and position of the positioning protrusions are arranged according to the specific structure of the door mounting seat to achieve multi-point positioning and improve installation stability.

[0010] Furthermore, the sealing block of the door mounting base and the storage base are detachably connected. The door mounting base has a positioning chamfer, the angle of which matches the outer contour of the sealing block, providing guidance during installation and enabling quick positioning. A through hole is provided on one side of the door mounting base, its position and diameter matching the through holes on the end housing of the storage base and the sealing block. The user completes the final fixing connection by passing bolts through these through holes. In addition, the door mounting base also includes a contoured fixing piece, the shape of which is designed according to the actual contour of the door frame of various car models. An adhesive layer is fixed to the outer wall of the contoured fixing piece; the adhesive layer is made of high-strength double-sided adhesive, which firmly adheres to the surface of the door frame during installation, thereby securing the door mounting base.

[0011] In another embodiment, a magnetic block is embedded in one side wall of the door mounting bracket. The number and position of the magnetic blocks are rationally distributed according to the size of the door mounting bracket, and their magnetic attraction is sufficient to overcome the gravity and friction of the door mounting bracket during initial positioning. When the door mounting bracket approaches the sealing block, the magnetic attraction between the magnetic blocks and the sealing block enables rapid positioning, further improving installation efficiency. Based on this, the user still needs to complete the final fixing connection with bolts to ensure the long-term stability of the door mounting bracket.

[0012] Furthermore, the connection between the roller blind roller and the torsion spring shaft within the storage base is a plug-in type. One end of the torsion spring shaft is inserted into the central hole of the roller blind roller and fixed by a limiting pin. The other end of the torsion spring shaft is connected to a sealing block, specifically limited by a mounting groove on the sealing block to prevent axial movement during use. A torsion spring is built into the torsion spring shaft, with one end fixed to the shaft and the other end fixed to the roller blind roller. When the shade net is pulled out, the torsion spring undergoes elastic deformation under stress; when the shade net needs to be retracted, the torsion spring releases its elastic potential energy, driving the roller blind roller to rotate and automatically winding the shade net back onto the roller blind roller.

[0013] Specifically, the sunshade net is made of high-density polyethylene fiber, which has excellent UV resistance and weather resistance, effectively blocking direct sunlight. The sunshade net is 0.3 mm to 0.5 mm thick, with a width of 1000 mm to 1500 mm designed according to common car door sizes, and a length of 1200 mm to 1800 mm to meet the needs of different vehicle models. One end of the sunshade net is fixed to the roller blind roller using a hot-melt welding process, and the other end is fixed to the positioning crossbar with screws, ensuring connection strength and durability.

[0014] Furthermore, the length of the positioning crossbar is consistent with the width of the sunshade net, and the cross-sectional shape of the crossbar is circular or elliptical with a diameter of 10 mm to 15 mm to ensure its rigidity and lightweight. The middle of the positioning crossbar is connected to a fastener via a pivot, and limit rings are provided at both ends of the pivot to prevent the fastener from falling off during use. The opening of the fastener faces the top hook of the door, and the inner side of the fastener is provided with anti-slip teeth. The tooth pitch of the anti-slip teeth is 1 mm to 2 mm, and the tooth height is 0.5 mm to 1 mm to enhance the friction between the fastener and the hook, preventing loosening.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] By replacing different door mounting brackets, the sunshade can be adapted to the doors of various car models, solving the problem of insufficient applicability of existing sunshades due to differences in car models. The detachable design of the sealing block and door mounting bracket, combined with positioning chamfers, through-hole alignment, and magnetic positioning functions, significantly improves the convenience and accuracy of installation. The sunshade net can be automatically stored in the storage base by rotating the roller blind, and extends through the long slot when in use, which is simple to operate and saves space. The design of the positioning crossbar and fasteners ensures that the sunshade net remains flat during use, preventing loosening or displacement.

[0017] In summary, this utility model, through its innovative structural design, enables the rapid assembly and disassembly of sunshades and their wide compatibility, demonstrating significant technical advantages and promising market application prospects. Attached Figure Description

[0025] Easy-to-install and remove car sunshades, combined with accessories Figure 1 To be continued Figure 5 This document details the structural design, installation process, and working principle of the sunshade. In this embodiment, the core components of the sunshade include a storage base 6, a sunshade net 1, a positioning crossbar 3, a sealing block, and a door mounting base 4. The following content will focus on the specific structure of each component and their interoperability, while also explaining the adaptation methods and usage scenarios of the sunshade on different vehicle models.

[0026] The storage base 6 is the main outer shell of the sunshade, made of high-strength plastic with good impact resistance. For example... Figure 1 As shown, one end of the storage base 6 is fixedly connected to the sealing block by bolts, while the other end has a through hole 5 for subsequent installation of the door mounting base 4. The storage base 6 contains a roller shutter roller and a torsion spring shaft, with the torsion spring shaft inserted into the center hole of the roller shutter roller and fixed by a limiting pin. The torsion spring shaft contains a torsion spring, one end of which is fixed to the torsion spring shaft, and the other end is fixed to the roller shutter roller. When the sunshade net 1 is pulled out, the torsion spring undergoes elastic deformation under stress; when the sunshade net 1 needs to be retracted, the torsion spring releases its elastic potential energy, driving the roller shutter roller to rotate and automatically winding the sunshade net 1 back onto the roller shutter roller. This design allows the sunshade net 1 to be quickly stored and extended during use, making operation convenient and space-saving.

[0027] The sunshade net 1 is made of high-density polyethylene fiber material, with a thickness of 0.3 mm to 0.5 mm, a width of 1000 mm to 1500 mm, and a length of 1200 mm to 1800 mm to fit common car door sizes. One end of the sunshade net 1 is fixed to the roller blind roller by hot-melt welding, and the other end is fixed to the positioning crossbar 3 by screws. The length of the positioning crossbar 3 is the same as the width of the sunshade net 1, and the cross-sectional shape is circular or elliptical with a diameter of 10 mm to 15 mm to ensure sufficient rigidity and lightweight characteristics. The middle of the positioning crossbar 3 is connected to the fastener 2 via a pivot, and the two ends of the pivot are equipped with limit rings to prevent the fastener 2 from falling off during use. The opening of the fastener 2 faces the top hook of the car door, and the inner side is provided with anti-slip teeth with a tooth pitch of 1 mm to 2 mm and a tooth height of 0.5 mm to 1 mm to enhance the friction between the fastener 2 and the hook and prevent loosening. Figure 3 As shown, when the sunshade net 1 extends from the long slot of the storage seat 6 and is laid flat on the door glass, the fastener 2 is engaged with the barb on the top of the door, thus completing the fixation of the sunshade net 1.

[0028] The design of the sealing block further improves the ease of installation of the sunshade. The sealing block and the storage base 6 are connected in a detachable manner. Initial positioning is achieved by the positioning protrusion 8 on the sealing block engaging with the groove on the end shell of the storage base 6, followed by final connection using bolts. Figure 2 As shown, the sealing block has an inwardly recessed mounting groove 7, and an inwardly extending positioning protrusion 8 is provided along the edge of the mounting groove 7. The depth and width of the mounting groove 7 are precisely matched with the corresponding dimensions of the door mounting seat 4, ensuring that the door mounting seat 4 will not shift during installation. The number and position of the positioning protrusions 8 are arranged according to the specific structure of the door mounting seat 4 to achieve multi-point positioning and improve installation stability.

[0029] The door mounting bracket 4 is one of the key innovations of this utility model. Its design aims to solve the problem of insufficient applicability of existing sunshades due to differences in vehicle models. Figure 4 As shown, the door mounting base 4 is provided with a positioning chamfer 11. The bevel angle of the positioning chamfer 11 matches the outer contour shape of the sealing block, serving as a guide during installation and enabling quick positioning. A through hole 5 is provided on one side of the door mounting base 4. The position and diameter of the through hole 5 are consistent with the through holes 5 on the end housing of the storage base 6 and the sealing block. The user completes the final fixing connection by passing bolts through the through holes 5. In addition, the door mounting base 4 also includes a contoured fixing piece 9. The shape of the contoured fixing piece 9 is designed according to the actual contour of the door frame of various car models. An adhesive layer 10 is fixed to the outer wall of the contoured fixing piece 9. The adhesive layer 10 is made of high-strength double-sided adhesive, which firmly adheres to the surface of the door frame during installation, thereby fixing the door mounting base 4. Figure 5As shown, in another embodiment, a magnetic block 12 is embedded and fixedly disposed on one side wall of the door mounting base 4. The number and position of the magnetic blocks 12 are reasonably distributed according to the size of the door mounting base 4, and the magnetic attraction force is sufficient to overcome the gravity and friction of the door mounting base 4 during initial positioning. When the door mounting base 4 approaches the sealing block, the magnetic attraction between the magnetic block 12 and the sealing block achieves rapid positioning, further improving installation efficiency. On this basis, the user still needs to complete the final fixed connection with bolts to ensure the long-term stability of the door mounting base 4.

[0030] This utility model of sunshade curtain has significant technical advantages in practical use. S1: First, select a door mounting base 4 compatible with the target vehicle model, quickly align it with the sealing block using the positioning chamfer 11, and achieve initial magnetic positioning using the magnetic block 12. S2: Subsequently, use bolts to pass through the through holes 5 on the door mounting base 4 and the through holes 5 on the storage base 6 and the sealing block to complete the final fixed connection. S3: Next, pull the sunshade net 1 out from the long slot of the storage base 6 until the sunshade net 1 completely covers the door glass. S4: Finally, snap the fastener 2 on the positioning crossbar 3 onto the pre-fixed hook at the top of the door to complete the fixing of the sunshade net 1. If a different vehicle model is needed, simply remove the door mounting base 4 and replace it with a door mounting base 4 compatible with the new model; there is no need to replace the entire sunshade curtain, thus achieving wide compatibility.

[0031] This utility model, through its innovative structural design, achieves rapid assembly and disassembly of the sunshade and broad compatibility, solving the problem of insufficient applicability of existing sunshades due to differences in vehicle models. The detachable design of the sealing block and door mounting base 4, combined with the positioning chamfer 11, through-hole 5 alignment, and magnetic positioning function, significantly improves the convenience and accuracy of installation. The sunshade net 1 can be automatically stored in the storage base 6 by the rotation of the roller blind roller, and extends through the long slot during use, making operation simple and space-saving. The design of the positioning crossbar 3 and fastener 2 ensures that the sunshade net 1 remains flat during use, preventing loosening or displacement. In summary, this utility model has significant technical advantages and promising market application prospects.
