When there are two telescopic frames 300, the telescopic frames 300 are installed at both the front and rear ends of the fixed frame 200.

[0036] The locking element 400 corresponds one-to-one with the telescopic frame 300, and is used to lock the telescopic frame 300 to different positions on the fixed frame 200. It can be understood that "the locking element 400 corresponds one-to-one with the telescopic frame 300" means that when there is one telescopic frame 300, one set of locking elements 400 is set; when there are two telescopic frames 300, two sets of locking elements 400 are set.

[0037] The car roof rack of this application adopts a longitudinally telescopic structure. A crossbar 100 is fixed to the roof of the vehicle, a mounting bracket 200 is fixed to the crossbar 100, and a telescopic bracket 300 can be adjusted in the front-rear direction relative to the mounting bracket 200 (e.g., ...). Figure 1 and Figure 5 As shown), after adjustment, the telescopic rack 300 can be locked by the locking piece 400. If the car is long, the car roof rack can be extended to increase the storage space. If the car is short, the car roof rack can be shortened to accommodate cars of shorter length. This adapts to different car models. When needed, the car roof rack can be extended; when not in use, it can be shortened, making it convenient and flexible to use.

[0038] In some embodiments, refer to Figures 1-5 The fixed frame 200 includes a base frame 210 fixed on the crossbar 100, a plurality of fixed guide rails 220 extending longitudinally and spaced apart on the base frame 210, and side guide rails 230 provided on both sides of the fixed guide rails 220.

[0039] The telescopic frame 300 includes multiple sliding guide rails 310 that are slidably connected between each fixed guide rail 220 and between the fixed guide rails 220 and the side guide rails 230 on both sides, and a connecting frame 320 fixed to the outer end of each sliding guide rail 310.

[0040] The above structure enables a telescopic connection between the telescopic frame 300 and the fixed frame 200, and when the telescopic frame 300 is retracted, the top surface of the luggage rack can form a flat surface (e.g., Figure 5 (As shown).

[0041] When the telescopic frame 300 extends, it forms a cantilever. In order to improve the stability of the connection between the telescopic frame 300 and the fixed frame 200, and thus improve the load-bearing capacity of the telescopic frame 300, guide grooves 221 are provided longitudinally on both sides of each fixed guide rail 220 and on the inner side of the side guide rail 230. Guide protrusions 311 that slide and adapt to the corresponding guide grooves 221 are provided on both sides of each sliding guide rail 310.

[0042] In some embodiments, the locking member 400 includes a locking unit disposed on at least one side of the corresponding telescopic frame 300. Here, "at least one side" means that the locking unit can be disposed on one side of the telescopic frame 300 or on both sides of the telescopic frame 300, preferably on both sides of the telescopic frame 300. When locking units are disposed on both sides of the telescopic frame 300, the telescopic frame 300 can only be telescopically adjusted after the locking units on both sides are unlocked simultaneously.

[0046] In this embodiment, the telescopic frame 300 can be locked in different positions by inserting the locking pin 410 into different positioning holes 312 on the sliding guide rail 310. The spring 420 can provide a spring force to keep the locking pin 410 inserted into the positioning hole 312. When unlocking is required, pull the locking pin 410 outward so that the inner end of the locking pin 410 exits the positioning hole 312 on the sliding guide rail 310, thereby releasing the lock between the telescopic frame 300 and the fixed frame 200. After unlocking, the telescopic frame 300 can be slidably adjusted.

[0047] In some embodiments, the base frame 210 is fixed to the crossbar 100 by a snap fastener. The base frame 210 and the crossbar 100 are installed by a snap fastener, which is convenient and quick to install.
