[0004] This utility model provides a quick-installation and quick-removal snowmobile windshield structure. By using a triangular fixing structure composed of barbs and two side locking pins, the use of bolts is reduced, thereby reducing the number of times the installation point needs to be disassembled and reassembled, achieving rapid installation and removal, and improving service life. To achieve the above objectives, this utility model adopts the following technical solution: A quick-installation and quick-removal snowmobile windshield structure includes a windshield, a mounting frame fixed to the front end of the windshield, support arms on both sides, and a mounting plate at the bottom of the support arms, with the mounting plate facing forward; a barb is provided on the lower surface of the mounting frame, with a first limiting block at the bottom of the barb facing backward; a locking pin is provided at one end of the lower surface of the support leg, a fixing ring is fitted on the locking pin, and a fixing hole is provided at the other end.

[0005] Preferably, the support arm is L-shaped, with a reinforcing plate and a mounting plate connected at the bend. The mounting plate is positioned nearly horizontally and fixed to the vehicle body. The L-shaped support arm has a simple structure, and together with the reinforcing plate, it can effectively enhance the support strength and ensure the stability of the windshield during driving; the near-horizontal mounting plate facilitates fixing to the vehicle body and improves the overall structural reliability.

[0006] Preferably, the mounting plate has several reinforcing ribs and is horizontally positioned. The front end of the mounting bracket is fixed to the front of the vehicle. Both ends of the mounting bracket are respectively located on both sides of the windshield, and rearview mirrors are provided at both ends of the mounting bracket. The reinforcing ribs can further enhance the load-bearing capacity of the mounting plate and prevent deformation due to external forces. The front end of the mounting bracket is fixed to the front of the vehicle, so that the windshield is tightly integrated with the front of the vehicle, improving the overall aesthetics and stability.

[0007] Preferably, a fixing element is installed through the fixing hole, and a reinforcing element is fitted onto the bottom end of the fixing element. The fixing element is preferably a bolt, with a locking pin for fixation and a screw for tightening, providing double-fixation for safety and reliability. This dual-fixation method of bolts and reinforcing elements enhances the windshield's stability, ensuring it will not loosen under complex road conditions and improving safety during use.

[0008] Preferably, the reinforcement is a rectangular frame with one end open, the upper surface of which is in close contact with the mounting plate, and the lower surface is inclined towards the mounting plate. The rectangular frame reinforcement design can better distribute the force, and the inclined lower surface can further enhance the stability of the structure and prevent the mounting plate from deforming or being damaged due to external impact.

[0009] Preferably, the bottom end of the locking pin is provided with a second limiting block, which is positioned facing the windshield side. The bottom end of the locking pin is provided with a guide portion, the longitudinal section of which is triangular.

[0010] Preferably, the retaining ring is positioned between the windshield and the second limiting block. The retaining ring further restricts the displacement of the windshield, ensuring its stability after installation and protecting the windshield edges from damage.

[0011] Preferably, the windshield is angled, and the mounting bracket covers the front of the windshield. The angled windshield better adapts to the aerodynamic design of the snowmobile, reducing wind resistance; the mounting bracket covering the front of the windshield enhances its protective capabilities while improving the overall aesthetics.

[0012] Preferably, the barb is L-shaped and located on the lower front surface of the mounting bracket. The L-shaped barb design allows for better fit with the vehicle body or other components, providing a fixing point, enhancing the installation stability of the windshield, and preventing loosening due to vibration.

[0013] Preferably, the barbs and the pins on both sides form a triangular fixing structure, all facing the windshield. This triangular fixing structure offers high stability, effectively distributing stress and ensuring the windshield remains stable under various operating conditions. It also simplifies the installation process and improves installation efficiency.

[0014] Beneficial effects: This utility model achieves rapid installation and removal of windshields through the cooperation of barbs, locking pins, and fixing rings, greatly improving the efficiency of maintenance and replacement and reducing installation time. The barb fixing limit and screw fastening provide double fixation, ensuring safety and reliability; minimizing the use of screws reduces the number of disassembly and assembly points, enabling rapid installation and removal, facilitating market maintenance and replacement, and extending the service life of plastic parts.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] In the actual use of snowmobiles, the ease of installation and stability of the windshield are crucial. Traditional snowmobile windshields rely heavily on bolts for fixing, which is not only time-consuming and laborious to install and disassemble, but also prone to damage to the mounting points due to frequent disassembly and assembly, affecting service life. The quick-installation and quick-removal snowmobile windshield structure proposed in this invention effectively solves these problems through an innovative triangular fixing structure and optimized component design.

[0023] like Figure 1 As shown, the snowmobile windshield structure uses the windshield 1 as its core component. The mounting bracket 2 fixed at its front end and the support arms 3 on both sides together form a stable load-bearing frame. The hooks 6 on the lower surface of the mounting bracket 2, together with the pins 11 on the lower surface of the support arms 3, form a unique triangular fixing structure. The first limiting block 14 at the bottom of the hook 6 faces rearward, acting like a sturdy "hook," allowing it to tightly engage with the corresponding structure on the vehicle during installation. A fixing ring 4 is fitted onto the pin 11 at one end of the lower surface of the support arm 3. The fixing ring 4 serves to protect and position the pin 11, preventing wear or displacement during use. The fixing hole 10 at the other end provides installation space for the fastener 15. This triangular fixing structure design eliminates the traditional method of using numerous bolts, greatly reducing the number of times the mounting points are disassembled and reassembled, making the installation and removal of the windshield 1 quick and easy.

[0024] like Figure 3 As shown, the support arm 3 adopts an L-shaped design, a simple and practical shape that offers significant advantages in structural mechanics. The bend in the L-shape connects the reinforcing plate 8 and the mounting plate 7, with the reinforcing plate 8 acting like a "skeleton" to enhance the overall strength of the support arm 3. During high-speed snowmobile operation, especially when traversing rugged snow terrain or encountering wind and snow, the reinforcing plate 8 effectively disperses the external force on the windshield 1, preventing the support arm 3 from deforming or breaking due to excessive stress, ensuring the windshield 1 remains stable. The near-horizontal mounting plate 7 ensures a high degree of fit with the vehicle body, allowing for secure fixation through specific installation techniques. This horizontal installation design not only facilitates construction but also allows the mounting plate 7 to evenly distribute the pressure from the windshield 1, further improving the overall structural reliability. Whether speeding across flat snowfields or navigating undulating mountain terrain, the L-shaped support arm 3, in conjunction with the reinforcing plate 8 and the horizontal mounting plate 7, provides solid support for the windshield 1.

[0025] like Figure 2As shown, several reinforcing ribs 9 added to the mounting plate 7 further enhance its load-bearing capacity. These reinforcing ribs 9 are evenly distributed on the surface of the mounting plate 7. When the windshield 1 is subjected to wind and snow resistance from the front, strong wind impact from the side, or bumps and vibrations during driving, the reinforcing ribs 9 can disperse and transmit these external forces, preventing the mounting plate 7 from deforming due to excessive local stress. At the same time, the front end of the mounting bracket 2 is firmly fixed to the front of the vehicle. This connection method makes the windshield 1 tightly integrated with the front of the vehicle, which not only improves the overall aesthetics of the snowmobile but also enhances the stability of the structure. The two ends of the mounting bracket 2 are located on both sides of the windshield 1, and rearview mirrors 5 are installed at both ends. The installation of the rearview mirrors 5 not only facilitates the driver's observation of the road conditions behind, but their integrated design with the mounting bracket 2 also further strengthens the structure of the windshield 1. In actual use, even in severe weather or complex road conditions, the synergistic effect of the reinforcing ribs 9 and the mounting bracket 2 can ensure that the windshield 1 remains stable as before, providing reliable visibility protection for the driver.

[0026] like Figure 3 As shown, the fastener 15 and the reinforcement 16, which pass through the fixing hole 10, constitute a double-fixing protection system. The fastener 15 is preferably a bolt. After the bolt passes through the fixing hole 10, it is connected to the vehicle body or other fixed structure, and the initial fixing is achieved by tightening the bolt. The locking pin 11 plays a limiting role in this process, ensuring that the windshield 1 is accurately positioned during fixing and will not shift. Subsequently, the bolt and other components are tightened with screws to form a double-fixing effect. This design fully considers the complexity of the snowmobile driving environment. On bumpy snowy roads, the double fixing method can effectively resist vibration and impact and prevent the windshield 1 from loosening. The reinforcement 16 adopts a rectangular frame structure with one open end, and its design is very ingenious. The upper surface of the rectangular frame fits tightly with the mounting plate 7 to ensure uniform force transmission; the lower surface is inclined towards the mounting plate 7. This inclination angle is carefully calculated so that when subjected to external impact, the force can be decomposed into multiple components in multiple directions, thereby better dispersing the force. When a snowmobile encounters strong winds or impacts, the inclined lower surface can guide the direction of external force, preventing the mounting plate 7 from deforming or being damaged due to concentrated force, thus further enhancing the stability and safety of the windshield 1 structure.

[0027] In actual installation, the operator only needs to align the hooks 6 of the windshield 1 with the corresponding slots on the vehicle body, gently press down to engage the hooks 6, then insert the pins 11 of the support arm 3 into the fixing holes 10 on the vehicle body, and finally secure it with bolts and reinforcement parts 16 to complete the installation. The entire process requires no complicated tools and is simple and quick to operate. Disassembly is achieved by reversing the steps, quickly removing the windshield 1, greatly saving time and labor costs. In long-term use, the reduced use of bolts and the number of disassemblies at the mounting points effectively reduces the risk of damage due to wear at the mounting points, significantly extending the service life of the windshield 1 structure. Whether it's the frequent disassembly and assembly requirements in professional snowmobile races or the convenient use requirements of daily snow driving, this utility model's quick-installation and quick-disassembly snowmobile windshield structure perfectly meets these needs, bringing a qualitative improvement to the snowmobile user experience and possessing significant practical value and broad prospects for promotion in the snowmobile accessories field.

[0028] like Figure 3 As shown, the locking pin 11, as a key component in the fixing structure, has a bottom design that fully considers the stability and convenience of installation. The second limiting block 12 at the bottom of the locking pin 11 faces the windshield 1, acting like a sturdy "protective wall." During installation, when the locking pin 11 is inserted into the fixing ring 4, the second limiting block 12 can fit tightly against the edge of the fixing ring 4, forming an effective blocking structure to prevent the locking pin 11 from slipping off when subjected to external impact or vibration. This design is particularly suitable for snowmobiles traveling on bumpy and complex road conditions. Even in the event of severe vibration, the second limiting block 12 can ensure that the locking pin 11 and the fixing ring 4 maintain a stable fit, preventing the windshield 1 from loosening or shifting. Simultaneously, the guide portion 13 at the bottom of the locking pin 11 adopts a triangular cross-section design, acting as a precise "guide." During installation, the operator only needs to align the locking pin 11 with the fixing ring 4, and the apex of the triangle will automatically guide the locking pin 11 to insert quickly, reducing alignment time and operational difficulty. Its smooth, beveled design effectively reduces friction during insertion, allowing the locking pin 11 to smoothly enter the retaining ring 4, significantly improving installation efficiency. Whether professional repair personnel are performing batch installations or car owners are replacing their windshields 1 themselves, this design can significantly shorten installation time and improve the user experience.

[0029] like Figure 5As shown, the fixing ring 4 further optimizes the fixing effect of the windshield 1. Located between the windshield 1 and the second limiting block 12, the fixing ring 4 serves multiple functions. Firstly, it acts as a "positioning ring," precisely limiting the displacement of the windshield 1. During high-speed snowmobile operation, the windshield 1 is subjected to various external forces, including wind pressure from the front, airflow from the sides, and vibrations from the ride. The fixing ring 4, through its tight cooperation with the locking pin 11 and the second limiting block 12, firmly fixes the windshield 1 in the predetermined position, ensuring it will not shake or shift due to external forces. Secondly, the fixing ring 4 also acts as a "protective cover." Its material is typically chosen for its cushioning properties, effectively absorbing external impacts and reducing direct collisions between the edge of the windshield 1 and other components, thus protecting the edge of the windshield 1 from damage. In long-term use, the presence of the fixing ring 4 not only extends the service life of the windshield 1 but also reduces replacement costs due to edge damage, bringing tangible economic benefits to the user.

[0030] like Figure 1 As shown, the tilted design of the windshield 1 and the layout of the mounting bracket 2 fully consider both aerodynamic and practical requirements. The tilted installation of the windshield 1 complements the overall shape of the snowmobile and effectively guides airflow. When the snowmobile travels at high speeds on snow, the tilted windshield 1 allows oncoming wind and snow to flow smoothly along the glass surface, reducing wind resistance and energy consumption. It also prevents snow accumulation on the glass surface, ensuring the driver always has a clear view. The mounting bracket 2 covers the front of the windshield 1, enhancing its protective capabilities and improving its overall aesthetics. The mounting bracket 2 is typically made of high-strength materials, providing additional protection in the event of an accidental impact, dispersing impact force, and preventing glass breakage. Furthermore, the design of the mounting bracket 2 harmonizes with the snowmobile's body lines, integrating the windshield 1 with the vehicle body, enhancing the overall quality and visual appeal of the vehicle, and satisfying users' dual needs for aesthetics and practicality. Figure 5As shown, the hook 6, as an important component of the triangular fixing structure, exhibits unique advantages with its L-shaped design. The L-shaped hook 6 is located on the lower front surface of the mounting bracket 2, a shape that perfectly matches the corresponding structure on the vehicle body. During installation, the L-shaped hook 6 easily hooks onto the fixing points on the vehicle body, forming a stable connection. Its right-angle bend design increases the fixing strength between the hook 6 and the fixing points, effectively preventing the hook 6 from loosening and falling off even under frequent vibrations from the snowmobile. Combined with the latches 11 on both sides, the hook 6 and latches 11 together form the triangular fixing structure. As the most stable geometric shape, the triangle can evenly distribute the external force on the windshield 1 to each fixing point. When the windshield 1 is subjected to frontal wind pressure, the hook 6 bears the upward pulling force, while the latches 11 resist the lateral pushing force. The three work together to ensure that the windshield 1 remains stable under various working conditions. This triangular fixing structure not only simplifies the installation process, eliminating the need for complex calibration and adjustment, but also reduces the wear and tear on the mounting points caused by traditional multi-bolt fixing methods, significantly improving installation efficiency and the service life of the windshield 1.

[0031] In practical applications, the advantages of this invention are fully demonstrated. Taking professional snowmobile races as an example, during pre-race vehicle maintenance, repair personnel can quickly inspect and replace the windshields 1 of multiple race cars using the quick-installation design of the hook 6, locking pin 11, and fixing ring 4. This saves a significant amount of time compared to traditional installation methods, ensuring vehicles can be put into the race on time. In daily use, when owners need to clean or replace the windshield 1 themselves, no professional tools are required; simple operation is all that's needed to complete the disassembly and assembly, lowering the barrier to entry. By reducing the use of screws and the number of disassemblies at installation points, the wear and tear on the windshield 1 and its mounting components is significantly reduced, effectively extending the lifespan of the plastic parts and reducing maintenance costs. Whether in extremely harsh snowy environments or everyday snow driving, the quick-installation and quick-removal snowmobile windshield structure of this invention provides users with a safe and comfortable driving experience thanks to its stable and reliable performance and convenient and efficient installation method. It has significant promotional value and broad application prospects in the snowmobile accessories field.

[0032] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
