Description

Technical Field

[0001] This utility model relates to the field of sunroof guide rails, and in particular to a car sunroof guide rail that can be quickly installed and disassembled. Background Technology

[0002] Car sunroofs utilize sunroof rails and sliders to slide the sunroof glass. A typical installation requires first inserting the slider into the rail, then securing the rail to the vehicle body, and finally connecting the glass to the slider. This sequence leads to the following problems during maintenance: When maintaining or replacing the slider or internal components of the rail, the glass confines the slider within the rail, and since the rail is fixed to the vehicle body, the slider cannot be directly removed. This results in blind spots and inefficiency during internal maintenance. Thorough maintenance requires disassembling the entire rail, a cumbersome and time-consuming process that increases complexity. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a car sunroof guide rail that can be quickly installed and disassembled, solving the problems of cumbersome maintenance and blind spots in the installation sequence of existing sunroof guide rails and sliders.

[0004] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0005] A quick-install and detachable car sunroof guide rail includes a guide rail and a slider inside the guide rail. The guide rail extends along a first direction. The inner sides of the left and right side walls of the guide rail are provided with first limiting strips extending along the first direction. The inner bottom side of the guide rail is provided with a second limiting strip extending along the first direction. The slider is hollow. The top two sides of the slider are provided with protruding edges that overlap the top surface of the guide rail. Side limiting blocks are slidably connected to the left and right sides of the slider. The outer side of the side limiting blocks is adapted to the inner wall of the guide rail. The bottom of the slider is provided with an avoidance groove to accommodate the second limiting strip. The avoidance groove is provided with a wrapping assembly that clamps the second limiting strip. The wrapping assembly and the two side limiting blocks are driven by a driving device inside the slider. The driving device drives the two limiting blocks to move away from each other to press against the side wall of the guide rail.

[0006] Optionally, there are two first limiting strips on the left and right sides of the guide rail, and two second limiting strips on the inner side of the bottom of the guide rail. Two first nesting grooves are provided on the opposite sides of the two side limiting blocks. When the two side limiting blocks abut against the inner wall of the guide rail, the first limiting strip is embedded in the first nesting groove. A connecting groove is formed on the top surface of the avoidance groove. The upper end of the connecting groove is connected to the inner cavity of the slider. The cross section of the second limiting strip is thicker at the top and thinner at the bottom.

[0007] Optionally, the wrapping assembly includes a rotating shaft symmetrically rotatably connected to the inner wall of the connecting groove. A wrapping strip is fixed in the middle of the rotating shaft. The length direction of the wrapping strip and the axial direction of the rotating shaft are both parallel to the first direction. The lower end of the wrapping strip extends into the clearance groove. When the slider is installed on the inner side of the guide rail, the two wrapping strips are respectively located on both sides of the second limiting strip. A torsion spring is sleeved on one end of the rotating shaft. One end of the torsion spring is fixed to the outer wall of the rotating shaft, and the other end is fixed to the inner wall of the connecting groove. Under the action of the torsion spring, the two wrapping strips expand in a figure-eight shape, and the opposite sides of the two wrapping strips abut against the inner wall of the clearance groove.

[0008] Optionally, the driving device includes a lifting and lowering driving disk disposed in the inner cavity of the slider. Two pairs of driving bars are fixed on the bottom surface of the driving disk. The lower end of each pair of driving bars extends into the corresponding connecting groove and fits against the inner wall of the connecting groove. The length direction of the driving bars is parallel to the first direction. Each pair of driving bars is respectively facing the outer wall of the opposite side of the two wrapping bars in the connecting groove. The cross section of the lower end of the driving bar is conical.

[0009] Two drive bars on the left and right sides are fixed with drive rods on opposite sides. Two side limit blocks are symmetrically fixed with a pair of drive plates on opposite sides. The drive plate is located between the pair of drive plates. The drive plates have inclined slots. The two ends of the left and right drive rods are inserted into the inclined slots on the two pairs of drive plates respectively.

[0010] Optionally, the driving device further includes a horizontal plate fixed in the middle of the upper end of the inner cavity of the slider. A screw is threadedly connected to the middle of the horizontal plate through a threaded hole. The lower end of the screw passes through the horizontal plate and is rotatably connected to the driving disk through a bearing.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] 1. Unlike traditional technologies, this utility model allows the slider to be removed directly from any position on the guide rail during maintenance, making the slider body, side limit block, wrapping component and internal mating surface of the guide rail fully exposed and accessible, completely eliminating maintenance blind spots. When maintaining or replacing parts, it is not necessary to disassemble the guide rail fixed to the car body, which significantly improves maintenance efficiency and quality and reduces operational complexity.

[0013] 2. This utility model uses a single screw to press down the drive plate, which simultaneously drives the two drive rods on both sides to move along the inclined groove, pushing the limit blocks on both sides away from each other and pressing against the side wall of the guide rail. Meanwhile, the tapered drive bar presses down, forcing the wrapping strip to overcome the torsion spring force and rotate inward, clamping the bottom limit bar. This achieves a fast and stable three-way locking of the slider in the left, right and bottom directions. The assembly and disassembly operations are simple and efficient, and the three-way limitation makes the connection between the slider and the guide rail more stable. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 5 This embodiment provides a car sunroof guide rail 1 that can be quickly installed and disassembled, including a guide rail 1 that extends along a first direction. The guide rail 1 has two first limiting strips 2 extending along the first direction on the inner side of the left and right side walls. The cross-section of the first limiting strip 2 is semi-circular. The guide rail 1 has two second limiting strips 3 extending along the first direction on the inner side of the bottom. The cross-section of the second limiting strip 3 is thicker at the top and thinner at the bottom.

[0022] A slider 4 is slidably installed inside the guide rail 1. The slider 4 is hollow, and the top two sides of the slider 4 have protruding edges 5 that overlap the top surface of the guide rail 1. The slider 4 is installed inside the guide rail 1, and its bottom surface abuts against the bottom inner side of the guide rail 1. The first limiting strip 2 and the second limiting strip 3 are used to limit and guide the slider 4 to prevent the slider 4 from directly detaching from the guide rail 1. The specific limiting structure is as follows:

[0023] The slider 4 has side sliding grooves 6 on both the left and right sides. Side limiting blocks 7 are slidably connected to the inner wall of the side sliding grooves 6. The upper part of the side sliding grooves 6 is connected to the inner cavity of the slider 4. Two first nesting grooves 8 are provided on the opposite side of the two side limiting blocks 7. After the slider 4 is inserted into the inner side of the guide rail 1, the two side limiting blocks 7 are pushed to expand each other and abut against the inner side of the left and right side walls of the guide rail 1 respectively. At the same time, the first limiting strip 2 is embedded in the first nesting groove 8. Since the length direction of the first limiting strip 2 and the second nesting groove 13 are both parallel to the first direction, the slider 4 can be limited and stably limited to the inner side of the guide rail 1 without slipping.

[0024] The bottom of the slider 4 is provided with a relief groove 9 to accommodate the second limiting strip 3. When the slider 4 is inserted into the inner side of the guide rail 1 along the inner cavity of the guide rail 1, the two relief grooves 9 are respectively aligned with the two second limiting strips 3. Only the bottom surface of the slider 4 touches the inner side of the bottom of the guide rail 1. At this time, the two second limiting strips 3 are just accommodated in the two relief grooves 9.

[0025] The top surface of the clearance groove 9 has a connecting groove 10. The upper end of the connecting groove 10 is connected to the inner cavity of the slider 4. The inner wall of the connecting groove 10 is symmetrically connected to the rotating shaft 11. The middle part of the rotating shaft 11 is fixed with a wrapping strip 12. The lower ends of the two wrapping strips 12 on opposite sides are formed with a second nesting groove 13. The length direction of the wrapping strip 12 and the axis of the rotating shaft 11 are parallel to the first direction. The lower end of the wrapping strip 12 extends into the clearance groove 9. When the slider 4 is installed inside the guide rail 1, the two wrapping strips 12 are located on both sides of the second limiting strip 3. When the two wrapping strips 12 are subjected to force, they move closer to each other and flip over. When they clamp the second limiting strip 3, the upper end of the second limiting strip 3 is embedded in the second nesting groove 13.

[0026] A torsion spring 15 is fitted at one end of the rotating shaft 11. One end of the torsion spring 15 is fixed to the outer wall of the rotating shaft 11, and the other end is fixed to the inner wall of the connecting groove 10. After the external force is lost, the two wrapping strips 12 expand in a figure-eight shape under the action of the torsion spring 15, and the opposite sides of the two wrapping strips 12 abut against the inner wall of the avoidance groove 9.

[0027] A horizontal plate 16 is fixed in the middle of the upper end of the inner cavity of the slider 4. A screw 17 is threadedly connected to the middle of the horizontal plate 16 through a threaded hole. The lower end of the screw 17 passes through the horizontal plate 16 and is rotatably connected to the drive plate 18 through a bearing. Two pairs of drive bars 19 are fixed on the bottom surface of the drive plate 18. The lower end of each pair of drive bars 19 extends into the corresponding connecting groove 10 and fits against the inner wall of the connecting groove 10. The length direction of the drive bar 19 is parallel to the first direction. Each pair of drive bars 19 is directly opposite to the outer wall of the two wrapping bars 12 in the connecting groove 10 on opposite sides. The cross section of the lower end of the drive bar 19 is tapered.

[0028] In the initial state, both wrapping strips 12 are in a figure-eight expanded posture, and the drive plate 21 is located at the upper end of the slider 4. At this time, by rotating the screw 17, since the lower end of each pair of drive strips 19 extends into the connecting groove 10 and is set against the inner wall of the connecting groove 10, the drive strips 19 are not driven to rotate together when the screw 17 is rotated. Instead, they are pushed by the screw 17 and slide downward along the inner wall of the connecting groove 10. Each pair of drive strips 19 abuts against the two wrapping strips 12 from opposite sides, and each opposite side of the two wrapping strips 12 has a sloping protrusion 14. The lower end of the drive strip 19 The conical part abuts against the inclined surface on the upper part of the inclined protrusion 14, thereby pushing the two wrapping strips 12 to flip towards each other. Finally, the driving strip 19 is fully inserted between the wrapping strip 12 and the inner wall of the connecting groove 10, so that the two wrapping strips 12 clamp the second limiting strip 3. The upper end of the second limiting strip 3 is embedded in the second nesting groove 13, thus limiting the slider 4 to the inner side of the guide rail 1. At this time, the screw 17 is completely submerged in the inner cavity of the slider 4. The slider 4 cannot be separated from the guide rail 1, but the second limiting strip 3 and the outer wall of the wrapping strip 12 can slide against each other, that is, the slider 4 can slide along the first direction inside the guide rail 1.

[0029] As for driving the side limiting blocks 7 on both sides, among the four driving bars 19 arranged side by side, the two outermost driving bars 19 are each fixed with a driving rod 20 on the opposite side. The two side limiting blocks 7 are each symmetrically fixed with a pair of driving plates 21 on the opposite side. The driving disk 18 is located between the pair of driving plates 21. The driving plate 21 has a slanted groove 22. The two ends of the left and right driving rods 20 are respectively inserted into the slanted grooves 22 on the two pairs of driving plates 21. When the screw 17 is turned to push the driving disk 18 to move downward, the driving rod 20 pushes the inner wall of the slanted groove 22, thereby pushing the two pairs of driving plates 21 on both sides away from each other, thereby pushing the two side limiting blocks 7 to slide in the direction away from each other, until the wrapping strip 12 wraps around the second limiting strip 3. At the same time, the first limiting strip 2 is embedded in the first nested groove 8. Then the slider 4 is completely limited and can slide inside the guide rail 1, completing the installation of the slider 4.

[0030] During disassembly, the drive plate 18 can be moved upward by rotating the screw 17 in the opposite direction, which causes each pair of wrapping strips 12 to expand and the two side limiting blocks 7 to converge.

[0031] In summary, during maintenance, the slider 4 can be directly removed from any position on the guide rail 1, allowing the slider 4 body, side limiting block 7, wrapping component and the internal mating surface of the guide rail 1 to be fully exposed and contacted without obstruction, completely eliminating maintenance blind spots. When maintaining or replacing parts, there is no need to disassemble the guide rail 1 fixed to the car body, which significantly improves maintenance efficiency and quality and reduces operational complexity.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
