Description

Technical Field

[0001] The present invention belongs to the technical field of roof rack installation, and particularly relates to a fixing device for an automobile roof rack. Background Art

[0002] At present, there are generally two common schemes for installing an automobile roof rack: external installation: welding studs on the roof cover, drilling holes on the roof rack, using nuts to fasten on the roof during assembly, and then adding a cover plate to cover the installation points; internal installation: drilling installation holes on the roof cover, the roof rack comes with bolts, using nuts to fasten inside the vehicle during assembly, and then using the roof lining to cover the installation points.

[0003] However, the external installation scheme requires adding a cover plate to cover the installation points, which will damage the overall aesthetics of the roof rack, and requires more processes and longer working hours during assembly, which is not conducive to improving the assembly efficiency. Second, the internal installation scheme will damage the sealing performance of the roof cover, and poor sealing will cause water leakage inside the vehicle, affecting the use experience of consumers. Summary of the Invention

[0004] The purpose of the present invention is to provide a fixing device for an automobile roof rack, which can hide the installation components inside the roof rack, improve the aesthetics, facilitate installation and disassembly, improve the installation efficiency, and can improve the safety after the roof rack is installed, so as to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A fixing device for an automobile roof rack, comprising a roof rack, a plastic bracket, and a T-shaped bracket. A square hole is opened on the roof rack. A single-sided clamp is provided on the plastic bracket. A trapezoidal installation groove and a card slot are opened on one side of the plastic bracket. The roof rack is fixedly clamped with the single-sided clamp through the square hole. The T-shaped bracket is provided with a sliding part and a clamping part. The side wall of the clamping part is in interference fit with the inner wall of the card slot. One end of the T-shaped bracket is fixedly welded with a fixing plate. A damping bushing is fixedly bonded to the side of the fixing plate. A damping rotating shaft is rotatably installed in the damping bushing. A hook is fixedly bonded to one end side of the damping rotating shaft. A groove is opened on the side edge of the roof rack. One side of the hook is in fit connection with the bottom of the groove.

[0007] Preferably, a sliding groove is opened on the side of the roof rack, and the square hole is opened in the sliding groove.

[0008] Preferably, a guiding block is provided on the plastic bracket, and the side wall of the guiding block is in sliding clearance fit with the inner wall of the square hole.

[0009] Preferably, the hook is J-shaped.

[0010] Preferably, two sets of unilateral cards are provided, and the number of square holes is the same as that of the unilateral cards.

[0011] Preferably, a spring is provided on one side of the plastic bracket, and one end of the spring is in fit connection with the bottom of the sliding groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. By using the plastic bracket, the installation components can be hidden inside the luggage rack, eliminating the need to add a cover plate to block the installation points, without damaging the overall aesthetics of the luggage rack. There are no installation holes on the roof cover sheet metal, and there is no risk of water seepage. The luggage rack can be quickly installed in the vehicle, is convenient to disassemble, simplifies the assembly process, and shortens the working hours required for assembly;

[0014] 2. By using the damping rotating shaft and the damping shaft sleeve in cooperation, the hook can be driven to rotate. After the luggage rack is installed, the hook rotates to clamp and wrap in the groove to provide anti-detachment protection for the luggage rack, improving the safety of the luggage rack after installation.
