Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts, and in particular relates to a windshield net component. Background Art

[0002] With the development of the automotive market, sunroofs have become widely used. Most sunroofs have the ability to open and tilt, improving interior brightness and ventilation, ensuring fresh air circulation, and enhancing passenger comfort. When the sunroof is opened, the windshield pops up to block airflow, effectively reducing wind speed, suppressing wind noise, and improving the driving experience.

[0003] The windshields currently in widespread use rely solely on torsion springs on both sides to spring the windshield frame to its highest point. The highest point is limited by the length of the mesh, but since the mesh is an elastic component, its spring-up height and inclination angle are difficult to guarantee. The injection mold needs to be repeatedly adjusted to obtain the required windshield height and inclination angle. Secondly, due to differences between mesh batches and differences in the properties of the mesh raw material yarn, the windshield height and inclination angle will vary. In addition, while the vehicle is in motion, the windshield height and inclination angle are easily affected by external forces, such as wind resistance, and there is a risk of generating large wind noise. Maintaining a stable windshield height and inclination angle requires strong elastic force in the torsion springs, but a large elastic force will increase the resistance that needs to be overcome when the sunroof glass is retracted. In addition, the lower end of the existing windshield is fixedly connected to the front frame of the sunroof, making it difficult to disassemble, resulting in high maintenance costs and poor parts interchangeability. Utility Model Content

[0004] In order to solve the above technical problems, the present invention provides a windshield net assembly. The technical solutions adopted by the present invention are as follows:

[0005] A windshield assembly comprises an upper frame, an upper side bar, a mesh, a lower side bar, a base, a torsion spring, and a lifting arm, wherein the lower side bar is clamped in a clamping slot of a skylight frame;

[0006] The upper frame is connected to the upper side bar, the mesh is provided between the upper side bar and the lower side bar, the two ends of the lifting arm are hinged to the upper frame and the base respectively, the rear end of the upper frame is provided with a socket, one end of the torsion spring is fixed to the base, and the other end of the torsion spring is inserted into the socket;

[0007] At least one protrusion is provided on the front wall of the slot, and the protrusion acts as a bayonet to limit the up and down movement of the lower side strip; at least two limiting bodies are provided on the bottom of the slot, and the lower side strip is located between the front wall of the slot and the limiting body to limit the forward and backward movement of the lower side strip; two limiting blocks are provided on the lower side strip, and the limiting blocks are connected to the side edges of the limiting body, one limiting block abuts the left side of the limiting body, and the other limiting block abuts the right side of the limiting body, and the cooperation between the limiting block and the limiting body limits the left and right movement of the lower side strip; a vertical disassembly groove is also provided on the front wall of the slot.

[0008] The windshield assembly of the present invention, when the windshield is in the open state and the vehicle is in motion, will be affected by the wind from the front of the vehicle, and the direction of the lifting arm and the direction of the wind will generate an opposing force, so that the windshield has enough supporting force to cope with the wind, and does not generate downward closing rotation. The windshield can always maintain the maximum opening state to achieve the purpose of self-locking, and does not generate shaking or abnormal noise; because the length of the lifting arm has limited the opening height of the windshield, there is no need to use a torsion spring with very large torsion force to maintain its maximum opening angle; only when the glass plate slides closed, the windshield pressure block applies force to the upper frame, the direction of the force is from the rear of the vehicle to the front of the vehicle, and generates a downward component of force on the upper frame, the upper frame will rotate downward with the axis of the torsion spring, and the lifting arm rotates with the connection position with the base below as the axis to press the windshield down and retract the windshield. At the same time, thanks to the use of the lifting arm, the windshield mesh will not be stretched by the torsion spring for a long time, causing it to relax due to the reduced force applied to the mesh. When the torsion spring force decays, wrinkles will not form, affecting the appearance, thereby increasing the service life of the torsion spring and mesh. Furthermore, the lower side bar is snapped into the corresponding slot in the sunroof frame, effectively restricting its forward, backward, upward, and left-right movement, thereby improving its stability. The removal slots facilitate the removal of the lower side bar. Simply insert a tool, such as a flat-bladed screwdriver, into the removal slot from above and pry lightly to remove the lower side bars on either side of the slot. This improves the interchangeability of parts, facilitates assembly and disassembly, and reduces installation and maintenance costs.

[0009] Furthermore, a plurality of protrusions are provided on the bottom of the slot, and the protrusions are located below the lower side bar.

[0010] The protrusions and the bumps better limit the up and down movement of the lower side bar, thereby increasing the stability of the lower side bar.

[0011] Furthermore, the limit block is arranged at a symmetrical position in the center of the lower side bar.

[0012] Since the lower side strip is a slender part, it is easier to position it in the center and avoid misalignment during installation. The windshield is more centered and symmetrical, which also reduces the difficulty of assembly.

[0013] Furthermore, the protrusion and the lower edge strip are provided with sloped surfaces.

[0014] The slope surface makes it easier for the lower side bar to be snapped into the slot during installation, which saves effort, facilitates installation, and improves installation efficiency.

[0015] Furthermore, the mesh is provided with side strips.

[0016] The side strips are installed on the mesh and can stabilize the wind load.

[0017] Furthermore, the upper frame is provided with a lock-shaped hole, and the upper end of the lifting arm is provided with a pin, and the pin includes two parallel edges and two arc edges, the width of the two parallel edges is adapted to the opening of the lock-shaped hole, and the two arc edges are adapted to the opening of the lock-shaped hole.

[0018] The lock-shaped holes on the upper frame and the pins on the lifting arms are easy to install, and after assembly, they will not fall out when the windshield is in the open or closed state.

[0019] The utility model windshield assembly can effectively control the windshield's spring-up height and tilt angle. Even when the windshield is subjected to a large external force of wind resistance, it can still maintain its posture, effectively suppressing wind noise and improving the driving experience. Secondly, due to the use of a lifting arm, the windshield torsion spring does not need a large amount of elastic force to maintain the windshield's height and tilt angle, reducing system load and fluctuations, and helping to improve system stability. Long-term use will not produce obvious appearance defects, extending the service life of the torsion spring and mesh. At the same time, the interchangeability of parts is improved, making disassembly and assembly more convenient and reducing installation and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to better understand the purpose, structure and function of the present invention, the present invention is described in further detail below with reference to the accompanying drawings.

[0037] Example:

[0038] like Figure 1-Figure 3As shown, a windshield net assembly includes an upper frame 4, an upper side bar 2, a mesh 1, a lower side bar 3, two bases 5, two torsion springs 7, and two lifting arms 8. The lower side bar 3 is clamped in the corresponding slot 10 of the skylight frame 9. The upper frame 4 is connected to the upper side bar 2, and the mesh 1 is provided between the upper side bar 2 and the lower side bar 3. The mesh 1 is provided with side strips 6, which can stabilize the wind load. The rear end of the upper frame 4 is provided with a socket, one end of the torsion spring 7 is fixed to the base 5, and the other end of the torsion spring 7 is inserted into the socket. The end of the torsion spring 7 inserted into the socket plays the role of bouncing up the upper frame 4, and can also slide in the socket along the axial direction to prevent mechanical interference during the opening and closing process. The two ends of the lifting arm 8 are respectively hinged on the upper frame 4 and the base 5. Among them, the upper frame 4 is provided with a lock-shaped hole 12, and the upper end of the lifting arm 8 is provided with a pin 11, and the pin 11 includes two parallel sides and two arc sides. The width of the two parallel sides is adapted to the opening of the lock-shaped hole 12, and the two arc sides are adapted to the opening of the lock-shaped hole 12. Figure 4-Figure 6 As shown, the lock-shaped hole 12 on the upper frame 4 and the pin 11 on the lifting arm 8 are easy to install, and after assembly, they will not fall out when the windshield is in the open state or the closed state.

[0039] like Figure 7-12 As shown, a plurality of protrusions 17 are provided on the front wall of the slot 10, and the protrusions 17 act as a bayonet. A plurality of protrusions 13 are provided on the bottom of the slot 10, and the protrusions 13 are located below the lower side bar 3. The protrusions 13 and the protrusions 17 restrict the up and down movement of the lower side bar 3. The protrusions 17 and the lower side bar 3 are provided with sloped surfaces, which facilitate the lower side bar 3 to be more easily snapped into the slot 10 during installation, saving effort, facilitating installation, and improving installation efficiency. A plurality of limiting bodies 14 are provided on the bottom of the slot 10, and the lower side strip 3 is located between the front wall of the slot 10 and the limiting body 14, limiting the forward and backward movement of the lower side strip 3; two limiting blocks 15 are provided on the lower side strip 3, and the limiting blocks 15 are arranged in a central symmetrical position of the lower side strip 3, and the limiting blocks 15 are in contact with the side edges of the limiting bodies 14; one of the limiting blocks 15 abuts against the left side of the limiting body 14, and the other limiting block 15 abuts against the right side of the limiting body 14, and the cooperation between the limiting blocks 15 and the limiting body 14 limits the left and right movement of the lower side strip 3; the lower side strip 3 is clamped in the slot 10 corresponding to the sunroof frame 9, and the forward and backward, up and down, left and right movements of the lower side strip 3 are well limited, thereby improving the stability of the lower side strip 3. A vertical disassembly groove 16 is further provided on the front wall of the card slot 10 . In this embodiment, the protrusions 17 are arranged in pairs, and the disassembly groove 16 is located between each pair of protrusions 17 . The disassembly groove 16 is more convenient for disassembling the lower side bar 3 .

[0040] When the lower side strip 3 is snapped into the slot 10 corresponding to the sunroof frame 9, first snap the lower side strip 3 in the middle position into the slot 10, then locate the position of the lower side strip 3 according to the limit block 15 on the lower side strip 3, and then press the lower side strip 3 from the middle to both sides in sequence; while pressing, pay attention to whether the lower side strip 3 is in the limit body 14, and the lower side strip 3 can be quickly snapped into the slot 10 corresponding to the sunroof frame 9. When the lower side strip 3 is removed from the slot 10 corresponding to the sunroof frame 9, it is only necessary to use a flat-blade screwdriver to insert it into the disassembly slot 16 from above and pry it slightly to remove the lower side strips 3 on both sides of the disassembly slot 16. The lower side strip 3 can then be quickly removed from the slot 10 of the sunroof frame 9, thereby improving the interchangeability of parts, making disassembly and assembly more convenient, and reducing installation and maintenance costs.

[0041] When the windshield is in the open state and the vehicle is in motion, it will be affected by the wind from the front direction, such as Figure 13 The force in the direction of A is the force generated by the lifting arm 8 in the direction of the wind, such as Figure 13 The force in the middle B direction provides the windshield with sufficient support to cope with the wind force, without causing downward rotation. The windshield can always maintain the maximum open state, achieving the purpose of self-locking, and without generating shaking or abnormal noise. Since the length of the lifting arm 8 has limited the opening height of the windshield, it is not necessary to use a torsion spring 7 with a very large torque to maintain it at the maximum opening angle. Figure 14 As shown, only when the glass panel slides closed does the windshield pressing block 18 exert a force on the upper frame 4 from the rear to the front of the vehicle, generating a downward force component on the upper frame 4. This causes the upper frame 4 to rotate downward about the axis of the torsion spring 7, and the lifting arm 8 rotates about its lower connection with the base 5, thereby pressing down and retracting the windshield. Furthermore, due to the use of the lifting arm 8, the windshield mesh 1 will not remain taut due to the extended upward tension of the torsion spring 7. This reduces the force applied to the mesh 1 and causes it to sag. When the torsion spring 7 weakens, wrinkles will not form, affecting the appearance. This increases the service life of the torsion spring 7 and the mesh 1.

[0042] In summary, the windshield assembly provided by the present invention effectively controls the windshield's spring-up height and tilt angle. Even when subjected to significant wind resistance, the windshield maintains its position, effectively suppressing wind noise and enhancing the riding experience. Furthermore, due to the use of the lifting arm 8, the windshield's torsion spring 7 does not require significant spring force to maintain the windshield's height and tilt angle, reducing system load and fluctuations and improving system stability. Long-term use also eliminates noticeable cosmetic defects, extending the service life of the torsion spring 7 and the mesh 1. Furthermore, the interchangeability of parts is improved, making assembly and disassembly more convenient and reducing installation and maintenance costs.

Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention.
