Description

Technical Field

[0001] This utility model belongs to the field of automotive windshield technology, specifically relating to a multi-position windshield opening and closing fixing mechanism. Background Technology

[0002] Early car windows were controlled by manually turning handles to raise and lower them. Later, electric window systems replaced manual operation, with electric motors controlling the opening and closing of the window glass. With technological advancements, electric windows incorporated multi-position adjustment systems to improve comfort and save energy. This system uses an electric motor and electronic switch, in conjunction with a transmission mechanism, to achieve different adjustment positions, ensuring the window glass remains stably at the preset position and preventing slippage or excessive raising or lowering. This design typically incorporates limit devices, gear systems, guide rails, and transmission systems to achieve precise positioning. To enhance stability and prevent glass from falling out, the structure requires high-strength materials, mechanical locking mechanisms, and support devices. Furthermore, the design must consider environmental factors such as wind, rain, dust, and ultraviolet radiation, selecting weather-resistant and wear-resistant materials to ensure long-term reliable use. In modern applications, multi-position control systems are increasingly being integrated with intelligent control systems.

[0003] Patent publication number CN111731080B discloses a dustproof structure for a car rear windshield, including a U-shaped body installed on the rear windshield. The U-shaped body includes an inner baffle, an outer baffle, and a base plate. The base plate is positioned between the inner and outer baffles. The inner baffle is located inside the outer baffle. The outer baffle has multiple equally spaced external holes, and the inner baffle has multiple equally spaced internal holes. The positions of the internal and external holes are staggered. A rubber pad is provided on the base plate, and a rubber brush is mounted on the rubber pad. Grooves are provided on the inner walls of the outer baffle and the facing internal holes, and the two sides of the rubber pad are engaged in these grooves. This patented U-shaped body first blocks the airflow within its range and creates multiple small vortices. Due to the simple structure of the U-shaped body, the rubber brush is easy to disassemble and install, and cleaning is also very convenient.

[0004] However, the current dustproof structure of automotive rear windshields has the following problems: traditional windshields are often fixed with glass glue, which is difficult to disassemble or requires forced removal. Therefore, we propose a multi-position windshield opening and closing fixing mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a multi-position windshield opening and closing fixing mechanism, which can solve the problem that traditional windshields are often fixed with glass glue, making them difficult to disassemble or requiring forced removal.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A multi-position windshield opening and closing fixing mechanism includes a support frame. A flip hinge is provided on the outer wall of the support frame. The end of the flip hinge away from the support frame is fixedly connected to the windshield. A top rod is rotatably connected to the inner wall of the support frame. The end of the top rod away from the support frame is rotatably connected to the side of the windshield near the support frame. A handle mounting base plate is fixedly connected to the side of the windshield near the support frame. A rotating handle is rotatably connected to the side of the handle mounting base plate away from the windshield. A windshield under-mount plate is fixedly connected to the side of the support frame away from the windshield.

[0008] The windshield is provided with an edge-sealing strip on the side near the supporting frame, and the edge-sealing strip is made of a high-toughness, soft material.

[0009] The outer wall of the support frame is located on the movement trajectory of the edge binding strip, and the lower windshield plate is double concave.

[0010] The notch of the lower windshield plate is located on the movement trajectory of the rotating handle block, and the windshield is designed with an outward arc shape.

[0011] The support frame is fixedly connected to a reinforcing rib at the bend, and the reinforcing rib is made of a high-hardness and high-toughness material.

[0012] The windshield can open to a maximum angle of degrees, and the inner wall of the support frame is in contact with the outer wall of the windshield.

[0013] The airflow assembly includes an extension rod, which is fixedly connected to the outer wall of the support frame, and an airflow plate is fixedly connected to the end of the extension rod away from the support frame.

[0014] The top of the airflow plate is sloped, and the airflow plate is made of a high-toughness material.

[0015] The technical effects achieved by this utility model are as follows:

[0016] This invention, through the arrangement of a support frame, a flip hinge, a windshield, an edge sealing strip, a top rod, a mounting plate under the handle, a rotating handle, a lower windshield retaining plate, and reinforcing ribs, enables the windshield to rotate, causing the edge sealing strip to rotate as well. This ensures that the edge sealing strip makes tight contact with the support frame and fills the gaps, allowing the device to achieve multiple opening and closing states, such as a fully closed state, a partially open state, and a fully open state. Thus, drivers and passengers can choose the opening and closing state according to their preferences and needs. Attached Figure Description

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1-6 As shown, a multi-position windshield opening and closing fixing mechanism includes a support frame 1. A flip hinge 2 is provided on the outer wall of the support frame 1. A windshield 3 is fixedly connected to the end of the flip hinge 2 away from the support frame 1. A top rod 5 is rotatably connected to the inner wall of the support frame 1. The end of the top rod 5 away from the support frame 1 is rotatably connected to the side of the windshield 3 near the support frame 1. A handle mounting base plate 6 is fixedly connected to the side of the windshield 3 near the support frame 1. A rotating handle 7 is rotatably connected to the side of the handle mounting base plate 6 away from the windshield 3. A windshield lower clamping plate 8 is fixedly connected to the side of the support frame 1 away from the windshield 3. The windshield lower clamping plate 8 can restrict the basic position of the windshield 3.

[0027] A sealing strip 4 is installed on the side of the windshield 3 near the supporting frame 1. The sealing strip 4 is made of a high-toughness, flexible material. It provides external pressure protection, reduces impact and friction, and is particularly effective in preventing breakage of vulnerable areas (such as glass and plastic panels). It also prevents dust and moisture from entering sealed areas (such as doors, windows, car doors, and appliance panels), improving sealing, insulation, soundproofing, and waterproofing. The elasticity of the sealing strip helps absorb impact, reducing vibration and noise, and is commonly used in automotive doors and windows. It also enhances the appearance, decorates product edges, and improves energy efficiency. Weather-resistant materials ensure resistance to UV rays, oxidation, and extreme weather, extending product lifespan. Its convenient design allows it to fit different shapes and sizes, increasing flexibility. In short, the sealing strip is a key component for improving product performance, appearance, comfort, and durability.

[0028] The outer wall of the supporting frame 1 lies on the movement trajectory of the edge-sealing strip 4. The lower windshield plate 8 has a double-concave design. In industrial design, the double concave shape helps to disperse external forces, making the stress distribution more uniform, thereby improving the strength and rigidity of the structure. For example, the double concave shape can effectively avoid excessive local stress concentration, helping to prevent material cracking or deformation. The double concave design can reduce the amount of material used without significantly reducing the overall strength. By reducing the thickness or volume of the material, a lightweight effect can be achieved, which is very important in the design of aerospace, automobiles, and other transportation vehicles. The double concave design helps to improve the stability of objects or structures, especially when facing external forces (such as wind, vibration, etc.). The double concave structure can make the center of gravity of the object more stable, reducing the possibility of swaying or instability.

[0029] The notch of the lower windshield plate 8 is located on the movement trajectory of the rotating handle 7, and the windshield 3 is set in an outward arc shape.

[0030] A reinforcing rib 9 is fixedly connected at the bend of the supporting frame 1. The reinforcing rib 9 is made of a high-hardness, high-toughness material. The reinforcing rib effectively distributes the load, increases the structure's load-bearing capacity, and prevents damage or instability due to excessive local stress. When subjected to external loads, the reinforcing rib effectively improves the stiffness of the material or structure, reducing deformation and deflection. For example, adding reinforcing ribs to thin-walled structures can significantly improve the bending strength. By changing the stress distribution, it can effectively reduce the deformation of materials under stress, especially preventing bending or twisting of long, thin materials under external forces. In some long or weak structures, reinforcing ribs help improve overall stability and prevent buckling or instability.

[0031] The windshield 3 can open to a maximum angle of 65 degrees. The necessary opening and closing angle can ensure the stable opening and closing of the windshield 3. The inner wall of the support frame 1 is in contact with the outer wall of the windshield 3. The necessary contact can ensure the stability of the device.

[0032] The airflow assembly includes an extension rod 10, which is fixedly connected to the outer wall of the support frame 1. An airflow plate 11 is fixedly connected to the end of the extension rod 10 away from the support frame 1.

[0033] The top of the airflow plate 11 is sloped, which can reduce the intensity of the airflow. The airflow plate 11 is made of a high-toughness material, which can ensure that the airflow plate 11 will not deform or be damaged when facing strong winds.

[0034] According to the above structure, when the windshield 3 needs to be opened, the operator manually rotates the rotating handle 7, so that the lower windshield retainer 8 no longer restricts the position of the rotating handle 7. At this time, the operator manually pushes the windshield 3, causing the windshield 3 to rotate under the constraint of the flip hinge 2, thereby opening the windshield 3. When the windshield needs to be closed, the operator manually pulls the rotating handle 7, causing the rotating handle 7 to drive the windshield 3 to rotate under the constraint of the flip hinge 2. The rotation of the windshield 3 causes the edge sealing strip 4 to rotate, so that the edge sealing strip 4 makes tight contact with the support frame 1 and fills the gap. This allows the device to achieve multiple opening and closing states, such as a fully closed state, a half-open state, and a fully open state. Moreover, when facing crosswinds and strong winds, the airflow deflector 11 can decompose and reduce the airflow intensity, thereby ensuring the overall safety of the device. In this way, drivers and passengers can choose the opening and closing state according to their preferences and needs.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
