Description

Technical Field

[0001] The utility model relates to the technical field of sunshade curtains, in particular to a spring installation structure of a sunshade curtain reel assembly for an automobile. Background Art

[0002] Large sunroofs and even panoramic sunroofs are popular on the cars on the market. The car sunroof sunshade can effectively block the sun and improve the driving experience of passengers in the car, so that the driver and passengers can enjoy a relatively open riding environment while being protected from the sun on sunny days. At present, the connection between the spring and the spring seat in the sunshade reel assembly is connected by the hook at one end of the spring and the protrusion on the side of the spring seat. As a result, the stress on the protrusion on the side of the spring seat and the spring hook part is relatively concentrated, resulting in uneven torque at one end of the reel and the other end, which in turn causes uneven force on both sides of the curtain, increasing the probability of wrinkles and waves on the curtain, resulting in unqualified performance of the sunshade.

[0004] Preferably, the limiting end is a U-shaped hook structure, and the middle portion of the limiting end passes through a through hole.

[0005] Preferably, the spring axial limiting structure is a spirally distributed installation groove, the installation groove is opened on the lower end surface of the spring fixing seat, and the end of the spring is installed inside the installation groove.

[0006] Preferably, the lower end of the guide groove is communicated with the mounting groove.

[0007] The technical effects and advantages of the utility model are as follows: the installation structure is provided with a radial through hole on the spring fixing seat, and a guide groove is provided on the side of the through hole, and the limiting end of the spring is placed inside the guide groove, so that the force-bearing area of ​​the spring and the spring seat is increased and the stress is more dispersed. At the same time, the force is closer to the point of action, the force on the curtain is more uniform, and the yield of the product in the production process is improved; the process and production method are not complicated, the difficulty can generally be achieved, it is easier to operate than the existing installation method, and the production efficiency is improved.

[0012] In order to make the technical means for realizing the utility model, creative features, objectives and effects easy to understand, the utility model is further explained below in conjunction with specific diagrams. In the description of the utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an integral connection or a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be internal communication between two components.

[0013] Example

[0014] like Figure 1-Figure 3 The spring mounting structure of a vehicle sunshade roller assembly is shown, comprising a spring 1, one end of which is mounted on a spring fixing seat 2, a through hole 3 is formed on the spring fixing seat 2, a limit end 4 is provided at the end of the spring 1, the limit end 4 is a U-shaped hook structure, the middle part of the limit end 4 passes through the through hole 3, a guide groove 5 is formed on one side of the spring fixing seat 2, the guide groove 5 is located below the through hole 3, one side of the limit end 4 is located inside the guide groove 5, the other end of the spring 1 has a smaller diameter and is sleeved on a locating pin 6, the end of the locating pin 6 passes through the spring fixing seat 2, a spirally distributed mounting groove 7 is provided on the lower end surface of the spring fixing seat 2, the mounting groove 7 is formed on the lower end surface of the spring fixing seat 2, the end of the spring 1 is mounted inside the mounting groove 7, the lower end of the guide groove 5 is connected to the mounting groove 7, and the spring 1 cooperates with the mounting groove 7 to achieve limiting along the axial extension direction of the locating pin.

[0015] The process flow and working principle of the utility model are as follows: when the sunshade curtain reel assembly is used, the limit end 4 of the spring 1 is installed inside the through hole 3, and the side is located inside the guide groove 5. After the sunshade curtain assembly is assembled (the curtain cloth is not stretched), the spring 1 is mainly subjected to the tensile force along the axial extension direction of the positioning pin and the radial torsion force of the spring fixing seat 2. The installation groove 7 cooperates with the spring 1 to improve the tensile force along the axial extension direction of the positioning pin, and the limit end 4 cooperates with the through hole 3 to improve the radial torsion force. Thereby, the force-bearing area is increased, the stress is more dispersed, and the force is closer to the point of action. The curtain cloth is more evenly stressed, which can improve the yield rate of the product in the production process.
