Description

Technical Field

[0001] This utility model relates to the field of automotive windshield mesh technology, and in particular to an automotive windshield mesh that can be quickly installed. Background Technology

[0002] With the development of the automotive industry and people's increasing demands for driving comfort, sunroofs have become a common feature in automobiles. However, when driving at high speeds with the sunroof open, the pressure difference between the inside and outside of the vehicle can cause strong wind noise and airflow turbulence, affecting the driving experience. As a common exterior component, the windshield mesh's main function is to effectively regulate airflow over the roof, reduce wind resistance, and weaken strong winds and noise entering the vehicle when the sunroof is open, thereby improving driving comfort and safety. Therefore, designing a windshield mesh that is easy to install and structurally reliable has significant market implications and practical value.

[0003] Currently, most commercially available car windshield grilles rely on bolts or clip-on clamps for installation. Specifically, the installation process typically involves placing the windshield grille's mounting bracket or base on the roof or the edge of the sunroof rails at a suitable location at the front of the sunroof. Then, the installer uses specific tools, such as screwdrivers and Allen wrenches, to thread multiple bolts through pre-drilled holes in the bracket and tighten them at the designated fixing points, or clamp them to the sunroof frame using the mechanical structure of the clamps. The entire installation process requires alignment and tightening to ensure the windshield grille can withstand strong winds at high speeds without loosening or detaching.

[0004] However, the aforementioned tool-based installation and removal methods have significant shortcomings, primarily due to the cumbersome and inconvenient nature of the process. For car owners, the windshield mesh is not a permanently fixed component; it often needs to be removed before entering an automatic car wash, during icy or snowy weather, or when the sunroof is not used for an extended period. Each removal and installation requires finding and using matching screwdrivers or wrenches, which is not only time-consuming and labor-intensive, but the repeated tightening and loosening of screws can also easily lead to wear or even damage to the threads. Furthermore, there is a risk of losing small bolts and other parts during the process, which is difficult to replace, causing great inconvenience to users and severely reducing the practicality of the windshield mesh as a convenient automotive accessory. Therefore, a quick-installation automotive windshield mesh solution is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quick-installable car windshield mesh, which is an improvement. Existing windshield mesh installation and removal methods rely on tools and are cumbersome. When car owners need to remove it for purposes such as car washing, it is not only time-consuming and laborious, but also carries the risk of parts wear or loss, greatly reducing the product's convenience and practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-installable car windshield mesh, comprising a sunroof guide rail, a sliding box slidably connected inside the sunroof guide rail, a connecting plate fixedly connected to one side of the outer wall of the sliding box, a fixing rod fixedly connected inside the connecting plate, a connecting frame rotatably connected to the outer wall of the fixing rod, an elastic strip fixedly connected to the lower surface of the connecting plate, a windshield mesh body fixedly connected to the lower surface of the connecting frame, an installation frame fixedly connected to the lower surface of the windshield mesh body, and a quick-installation mechanism installed inside the installation frame;

[0007] The quick-installation mechanism includes a plug rod, a locking block slidably connected to the lower side of the plug rod, a wedge groove penetrating the inside of the locking block, the locking block engaging with the lower surface of the sunroof guide rail, a spring fixedly connected to one side of the outer wall of the locking block, a wedge block slidably connected to the upper side of the plug rod, the outer wall of the wedge block slidably connected to the inner wall of the wedge groove, a sliding rod fixedly connected to the upper surface of the wedge block, a spring two sleeved on the outer wall of the sliding rod, and a push-out component installed on the upper surface of the plug rod.

[0008] Furthermore, the ejection assembly includes a second connecting bracket, the lower surface of which is fixedly connected to the upper surface of the insert rod, and a third spring is fixedly connected to the lower surface of the second connecting bracket, the lower surface of which abuts against the upper surface of the sunroof guide rail.

[0009] Furthermore, a limiting frame is slidably connected inside the sliding box, and a groove for the limiting frame to slide is provided inside the sliding box. A limiting slide rail is fixedly connected to the inner wall of the sunroof guide rail near the sliding box, and one end of the fixing rod is slidably connected inside the limiting slide rail.

[0010] Furthermore, a roller is rotatably connected inside the limiting frame, and a hinge seat is fixedly connected to the upper surface of the limiting frame.

[0011] Furthermore, the hinge seat is rotatably connected to two symmetrical rotating plates, and each of the two rotating plates is fixedly connected to a connecting rod.

[0012] Furthermore, rollers are rotatably connected to the outer walls of both connecting rods, and springs are provided between the two connecting rods.

[0013] Furthermore, a roller three is rotatably connected to one side of the outer wall of the sliding box, and the outer wall of the roller three abuts against the inner wall of the sunroof guide rail on the side relative to the limiting slide rail.

[0014] Furthermore, the upper end of the second spring is fixedly connected to the upper surface of the inner wall of the insertion rod, and the lower end of the second spring is fixedly connected to the upper surface of the wedge block.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, during installation, the user only needs to align the insertion rod of the mounting bracket with the sunroof guide rail and press it down. The preload of spring one will automatically drive the locking block to extend outward and firmly engage with the bottom of the sunroof guide rail, achieving instant locking. During disassembly, simply press the sliding rod. Through the linkage between the wedge block and the wedge groove, the locking block can be forcibly retracted to release the lock. At the same time, the compressed spring three will immediately generate a reaction force to pop the entire mounting bracket upward, achieving rapid separation. This series of one-click installation and one-click disassembly operations, which require no auxiliary tools, completely solves the problems of cumbersome, time-consuming, and easy loss of parts caused by the reliance on tools for disassembly and assembly in existing technologies, significantly enhancing the practicality of the product.

[0017] 2. In this invention, when the sliding box slides inside the sunroof guide rail, its external roller three and internal limiting frame roller one work together to form stable multi-point rolling support on the inner wall of the guide rail, significantly reducing sliding friction. Simultaneously, the rotating plate driven by spring four and roller two inside the limiting frame constitute an adaptive adjustment mechanism that can compensate for minute gaps and deviations during the sliding process in real time, ensuring the sliding box always maintains the correct posture. This structure, combined with the buffering force provided by the elastic strip, ensures that the windshield can move smoothly and without impact under various working conditions, improving product reliability and user experience.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-6 This utility model provides an embodiment of a car windshield mesh that can be quickly installed, including a car sunroof guide rail 1 as an installation base and sliding track. A sliding box 3, which serves as a moving carrier for the windshield mesh, is slidably connected inside the sunroof guide rail 1. One side of the outer wall of the sliding box 3 is connected to a connecting plate 4 by a fixed connection. A fixed rod 5, which provides support and guidance, is firmly fixed inside the connecting plate 4. The outer wall of the fixed rod 5 is rotatably connected to a connecting frame 6 for connecting the windshield mesh. An elastic strip 7, which provides buffering or auxiliary reset during sliding, is also fixedly connected to the lower surface of the connecting plate 4. The lower surface of the connecting frame 6 is finally fixedly connected to the windshield mesh body 8, which performs the main function. The lower surface of the windshield mesh body 8 is fixedly connected to a mounting frame 9 for fixing the entire device to the car body. The mounting frame 9 integrates a quick-installation mechanism that enables tool-free disassembly and assembly.

[0028] The quick-release mechanism includes a rod 10 as its main structure. A locking block 11 is movably slidably connected to the lower interior of the rod 10. A driven wedge groove 12 is formed through the interior of the locking block 11. In the working state, the locking block 11 engages with the lower surface of the sunroof guide rail 1 to form a fixed position. A spring 13 providing ejection force is also fixedly connected to one side of the outer wall of the locking block 11. An unlocking wedge 14 is slidably connected to the upper interior of the rod 10. The outer wall of the wedge 14 can slide against the inner wall of the wedge groove 12. A sliding rod 15 for user pressing is fixedly connected to the upper surface of the wedge 14. A spring 16 for resetting the sliding rod 15 is sleeved on its outer wall. In addition, a push-out assembly for assisting disassembly is installed on the upper surface of the insert rod 10. The push-out assembly includes a connecting bracket 2 18 for support, the lower surface of which is fixedly connected to the upper surface of the insert rod 10. A spring 3 17 that provides a pop-out force when unlocking is also fixedly connected to the lower surface of the connecting bracket 2 18. The lower surface of the spring 3 17 abuts against the upper surface of the sunroof guide rail 1 to form a preload. To ensure the normal operation of each component, the upper end of the spring 2 16 is fixedly connected to the upper surface of the inner wall of the insert rod 10, and its lower end is fixedly connected to the upper surface of the wedge block 14.

[0029] Specifically, during installation, simply align and press the insert rod 10 into the sunroof guide rail 1. Guided by the edge of the guide rail, the locking block 11 first retracts inward, then automatically pops out under the action of spring 13 after passing the edge, locking the lower edge of the guide rail. During disassembly, press the sliding rod 15, and the linkage between the wedge block 14 and the wedge groove 12 forces the locking block 11 to retract. At the moment of unlocking, the pre-compressed spring 17 immediately releases energy, popping the entire mounting bracket 9 upward for rapid separation. Components such as the sliding box 3 and the connecting plate 4 ensure that the windshield mesh body 8 can smoothly unfold and retract along the sunroof guide rail 1, meeting daily usage needs.

[0030] Reference Figures 1-6Inside the sliding box 3, a limiting frame 19, which serves as a guide and support, is slidably connected. To ensure smooth movement, a groove is provided inside the sliding box 3 for the limiting frame 19 to slide. Simultaneously, a limiting slide rail 2 is fixedly connected to the inner wall of the sunroof guide rail 1 near the sliding box 3. One end of the fixing rod 5 is slidably connected inside the limiting slide rail 2, thus providing the main direction for the movement of the entire sliding box 3. To further reduce friction and improve stability, a roller 20 is rotatably connected inside the limiting frame 19, contacting the inner wall of the sunroof guide rail 1. A hinge seat 21, serving as a mounting base, is also fixedly connected to the upper surface of the limiting frame 19. Rotating plates 22, symmetrically distributed on both sides, are rotatably connected inside the hinge seat 21. Connecting rods 23, acting as levers, are fixedly connected inside each of the two rotating plates 22. Rollers 24, which roll inside the sliding box 3, are rotatably connected to the outer walls of the two connecting rods 23. A spring 25, providing tension, is also provided between the two connecting rods 23. In addition, a roller 26 is rotatably connected to one side of the outer wall of the sliding box 3, and the outer wall of the roller 26 abuts against the other side of the limit rail 2 on the inner wall of the sunroof guide rail 1.

[0031] Specifically, to ensure that the sliding carrier, namely the sliding box 3, can move smoothly and stably inside the sunroof guide rail 1 during the unfolding and retraction of the windshield, it is necessary to prevent jamming. During operation, the sliding of the fixing rod 5 within the limiting slide rail 2 provides basic linear guidance for the overall movement. Simultaneously, the roller 26 on the other side of the sliding box 3 and the roller 20 inside it together form multi-point rolling support on the inner wall of the sunroof guide rail 1, greatly reducing sliding friction resistance. More importantly, the rotating plate 22 driven by the spring 25, the connecting rod 23, and the roller 24 constitute an internal tensioning mechanism. This mechanism continuously applies a dynamic and adaptive support force to the limiting frame 19, ensuring that the roller 20 can always stably abut against the inner wall of the guide rail, effectively eliminating wobbling that may be caused by gaps or tolerances, thus ensuring the smoothness and reliability of the entire opening and closing process.

[0032] Working principle: When the device is needed, firstly, slide the sliding box 3 connected to the windshield mesh body 8 into the sunroof guide rail 1 of the car from the port; then, place the mounting bracket 9 on the upper surface of the sunroof guide rail 1, align it and press it vertically downward; during the pressing process, the insert rod 10 enters the interior of the sunroof guide rail 1, and the locking block 11 below it is pushed inward when it contacts the edge of the guide rail. After passing the edge of the guide rail, the locking block 11 is quickly ejected outward under the elastic force of the spring 13 on one side, and its structural surface is firmly locked into the lower surface of the sunroof guide rail 1, completing the locking; during this process, the spring 17 located between the insert rod 10 and the sunroof guide rail 1 is compressed to store potential energy for quick disassembly;

[0033] Secondly, after the windshield is installed, the extension and retraction of the windshield body 8 is achieved by the sliding box 3 sliding within the sunroof guide rail 1. When the sliding box 3 moves, the roller 26 on its outer wall and the roller 20 on its inner limit frame 19 roll against the inner wall of the sunroof guide rail 1, while the fixing rod 5 slides within the limit rail 2, together forming a stable and low-friction guiding system. The spring 25 inside the limit frame 19 provides elastic support to the top of the sliding box 3 through the rotating plate 22 and the roller 24, realizing dynamic posture adjustment and effectively preventing jamming during movement. The elastic strip 7 provides a certain auxiliary force when retracting.

[0034] Finally, when it is necessary to remove the windshield, the operator presses down on the sliding rod 15 on the mounting bracket 9 with their finger; the sliding rod 15 drives the wedge block 14 at its lower end to move downward, and the wedge block 14 slides into the wedge groove 12 inside the locking block 11; due to the action of the wedge-shaped surface, the wedge block 14 will generate a horizontal pushing force on the locking block 11, forcing the locking block 11 to overcome the elastic force of the spring 13 and retract into the insert rod 10, thereby disengaging from the lower surface of the sunroof guide rail 1; at the moment the locking state is released, the previously compressed spring 17 quickly releases its elastic force, pushing the entire mounting bracket 9 upward, so that the windshield body 8 is quickly separated from the sunroof guide rail 1, realizing one-click disassembly.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
