Description

Technical Field

[0001] This utility model relates to the field of sunroof sliding rail assembly tooling technology. Background Technology

[0002] The sunroof sliding rail has mushroom-shaped hook-and-loop fasteners for attaching to the headliner, but manually measuring the position of these fasteners is tedious and time-consuming. Currently, many vehicle components have corresponding positioning devices for installation. For example, the patent publication CN207326803U, published on May 8, 2018, entitled "Fender Marking Positioning Fixture and Hand-held Positioning Fixture," discloses a fender marking positioning fixture including a fixture body with positioning holes matching the shape of the marking; the fixture body also has at least two positioning parts, which enable the positioning holes to be accurately positioned on the marking on the fender. The hand-held positioning fixture includes the fender marking positioning fixture described above, and also includes a hand-held structure fixed to the fixture body.

[0003] The placement of the mushroom-shaped hook and loop fasteners is crucial. Misalignment can prevent effective connection to the roof, leading to issues such as protruding tracks or light leaks from the roof. To address this, a custom-designed tool for attaching mushroom-shaped hook and loop fasteners to the sunroof tracks is urgently needed to improve the efficiency and accuracy of installation. Summary of the Invention

[0017] The following description, with reference to the accompanying drawings, details the specific implementation of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the function and working principle of each part, the manufacturing process, and the operation and use methods. This will help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of this utility model.

[0018] The mushroom-shaped hook-and-loop fastener positioning device for car sunroof rails is used to assist in the pasting of the mushroom-shaped hook-and-loop fasteners. The back of the mushroom-shaped hook-and-loop fastener has adhesive. When operating it, the operator needs to find the correct pasting position, then peel off the protective film of the adhesive backing, and then paste it onto the corresponding position on the car sunroof rail. The car sunroof rail has a flat strip structure, so when positioning it, it is necessary to insert the positioning pin 4 vertically, and then use the lateral support structure for positioning, so that the positioning device can reliably contact the car sunroof rail. After that, leave the position on the car sunroof rail where the mushroom-shaped hook-and-loop fastener needs to be pasted. Then, the pre-reserved space on the positioning device can be used for alignment and pasting, so that the assembly (pasting) process of the mushroom-shaped hook-and-loop fastener can be completed relatively efficiently and accurately.

[0019] The main body of the positioning device is a strip-shaped metal part, namely the positioning support strip 1. The length of the positioning support strip 1 is close to that of the car sunroof rail. The car sunroof rail is provided with positioning pins 4 for insertion into the mounting holes of the car sunroof rail. When the positioning support strip 1 is placed on the car sunroof rail, the positioning pins 4 at both ends can be inserted into the mounting holes at both ends of the car sunroof rail to achieve positioning. However, since the positioning pins 4 and the mounting holes are clearance fit, the positioning support strip 1 can still sway relative to the car sunroof rail after being inserted into the mounting holes. In order to provide lateral support for the positioning support strip 1 and ensure the reliability of the positioning support strip 1, the lower surface of the positioning support strip 1 is provided with multiple protruding limiting blocks 2 for contacting the side of the car sunroof rail. The limiting blocks 2 can support the side of the car sunroof rail and provide lateral support for the positioning support strip 1. The number of limiting blocks 2 is at least two. It is necessary to ensure that when the positioning pins 4 on the positioning support strip 1 are inserted into the mounting holes, the limiting blocks 2 are in tight contact with the side of the car sunroof rail.

[0020] To ensure a tight fit between the limiting block 2 and the sunroof rail, the limiting block 2 has an elastic support pad 3 on the side facing the sunroof rail. When the positioning pin 4 on the positioning support strip 1 is inserted into the mounting hole, the elastic support pad 3 is slightly deformed under pressure. The elastic support pad 3 helps the positioning pin 4 to clamp the sunroof rail, ensuring the reliability of the positioning of the positioning support strip 1. Then, the positioning notch 9 on the positioning support strip 1 assists in the pasting of the mushroom-shaped hook and loop fastener. The position and length of the positioning notch 9 are determined according to the pasting position and length of the mushroom-shaped hook and loop fastener. The length of the positioning notch 9 is the same as the length of the mushroom-shaped hook and loop fastener to be installed.

[0021] To facilitate operation of the positioning support strip 1, two handles 6 are fixed on the upper surface of the positioning support strip 1. At the same time, magnets for adhering to the sunroof rail are embedded at both ends of the positioning support strip 1. After the positioning support strip 1 is placed in place, the two positioning pins 4 are inserted into the mounting holes at both ends of the sunroof rail. The limiting block 2 and the elastic support pad 3 are in close contact with the side of the sunroof rail. The magnets can completely fix the positioning support strip 1 to the sunroof rail by adhering to both ends of the sunroof rail. When the operator releases their hands, the positioning support strip 1 will not move relative to the sunroof rail, and the mushroom-shaped fastener can be attached again.

[0022] The preferred approach is to design one of the locating pins 4 as a movable pin 5 that can move up and down, such as... Figure 2 As shown, the positioning support strip 1 at one end of the movable pin 5 has a hole for the movable pin 5 to move up and down, that is, the inner diameter of the hole is larger than the outer diameter of the movable pin 5. The overall shape of the movable pin 5 is a cylindrical structure. A strip-shaped through hole along the axis of the movable positioning pin 4 forms a slide groove 8. A pin tongue 7 is horizontally placed on the hole and embedded in the slide groove 8. The pin tongue 7 has a plate-like structure, so that the movable pin 5 can only move up and down along the hole and cannot be rotated. The two ends of the pin tongue 7 are fixed to the edge of the hole. The lower edge of the pin tongue 7 has a gap relative to the plane of the positioning support strip 1. In actual operation, the positioning pin 4 is first inserted into the mounting hole at one end of the car sunroof slide rail. There is an angle between the car sunroof slide rail and the positioning support strip 1. Then, with the positioning pin 4 as the center, the movable pin 5 moves up and down. Rotate the positioning support strip 1 to align it with the sunroof track. During this process, the movable pin 5, supported by the edge of the sunroof track, protrudes upwards. Because the lower edge of the pin tongue 7 has a gap relative to the plane of the positioning support strip 1, the bottom end of the movable pin 5 can contact the sunroof track, and the positioning support strip 1 is also in close contact with the sunroof track. When the movable pin 5 is rotated to correspond with another mounting hole, the movable pin 5 will fall into the mounting hole under its own weight, achieving positioning and locking. At the same time, the limiting block 2 and the elastic support pad 3 can also be in close contact with the side of the sunroof track. Then, the mushroom-shaped fasteners can be pasted one by one. After pasting, lift the movable pin 5 and rotate the positioning support strip 1 slightly to easily remove the positioning device.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
