[0043] Optimally, the above-mentioned support rod includes a support cross bar 131, a support vertical bar 132 and a main body bar 133, see Figure 2 ;in,

[0044] There are two support cross bars 131 and two support vertical bars 132, and the two support cross bars 131 and the two support vertical bars 132 form a rectangular frame structure. The connection between the support cross bars 131 and the support vertical bars 132 is connected and fixed by a connecting rod 11;

[0045] There are multiple main rods 133, which are evenly spaced between two support vertical rods 132 along the length direction of the support vertical rods 132, and both ends of the main rods 133 are respectively connected and fixed to the two support vertical rods 132 to enhance the structural stability of the luggage rack body 1.

[0046] Optimally, the connecting rod 11 is a bent rod, and the angle between the axes at both ends of the connecting rod 11 is 90°. Figure 3 , the support cross bar 131 and the support vertical bar 132 are connected and fixed by the connecting rod 11;

[0047] The connecting rod 11 of the bent rod structure makes the four top corners of the luggage rack body 1 all rounded, making the appearance of the luggage rack body 1 more beautiful, and the luggage rack body 1 without sharp corners will not scratch the user during use, installation and disassembly, making it safer when in use.

[0048] Optimally, both ends of the connecting rod 11 are provided with protrusions 111, see again Figure 3 , the extension direction of the protrusion 111 is parallel to the axis of the end of the connecting rod 11;

[0049] The ends of the above-mentioned support cross bar 131 and support vertical bar 132 are both provided with slots 134 matching with the protrusion 111. The support cross bar 131 and support vertical bar 132 are both inserted into the end of the connecting rod 11 through the cooperation of the slots 134 and the protrusion 111, so as to make the installation of the luggage rack body 1 more convenient.

[0050] Optimally, the luggage rack body 1 further comprises a connecting piece;

[0051] The end of the connecting piece is inserted into the slot 134 from the outside of the supporting cross bar 131 or the supporting vertical bar 132 and connected to the protrusion 111 to further improve the stability of the connection between the supporting cross bar 131 and the supporting vertical bar 132 and the connecting rod 11, thereby making the structure of the luggage rack body 1 more stable.

[0052] It should be noted that the above-mentioned connecting pieces are bolts.

[0053] Optimally, the side wall of the protruding portion 111 is provided with a clamping portion, which is arranged circumferentially around the protruding portion 111, and the circumferential side wall of the slot 134 is provided with a clamping groove matching the clamping portion;

[0054] When inserting the support cross bar 131 or the support vertical bar 132, the slot 134 on the support cross bar 131 or the support vertical bar 132 can be aligned with the protruding portion 111 and inserted in a direction close to the connecting piece until the clamping groove in the slot 134 is clamped on the clamping portion on the protruding portion 111 to achieve the fixation of the support cross bar 131 or the support vertical bar 132 and the connecting portion, and then the connecting piece is inserted into the slot 134 from the outside of the support cross bar 131 or the support vertical bar 132 and connected to the protruding portion 111 to achieve the fixation of the support cross bar 131 or the support vertical bar 132 and the connecting portion, so as to make the structure of the luggage rack body 1 more stable;

[0055] Furthermore, the locking groove provided in the slot 134 and the locking portion provided on the protruding portion 111 can prevent the supporting cross bar 131 or the supporting vertical bar 132 from falling off the connecting portion.

[0056] It should be noted that the connecting rod 11 made of a composite material has a certain toughness. When the supporting cross bar 131 or the supporting vertical bar 132 is inserted into the end of the connecting rod 11, the clamping part on the protrusion 111 will be deformed to a certain extent when it is inserted into the slot 134, so that the protrusion 111 can be smoothly inserted into the slot 134, making the installation of the support assembly more convenient.

[0057] Optimally, the above-mentioned automobile luggage rack further includes a fixing claw 3;

[0058] The luggage rack body 1 is detachably mounted on the fixing seat 2 by means of the fixing claws 3, so that the disassembly and assembly of the luggage rack body 1 is more convenient, and the car owner has more choices. When driving on city roads, the luggage rack body 1 can be removed, thereby reducing the weight of the whole vehicle and reducing wind resistance, thereby reducing the fuel consumption of the car.

[0059] Preferably, the above-mentioned fixing claw 3 includes a fixing portion and a clamping portion; wherein,

[0060] The fixing portion is fixedly arranged below the luggage rack body 1, and the clamping portion is detachably arranged on the side wall of the fixing portion by means of bolts or other connecting parts. The fixing portion and the clamping portion are both provided with semicircular clamping portions at one end close to the fixing seat 2, and the fixing portion and the clamping portion are clamped and fixed on the fixing seat 2 by means of a clamp formed by the cooperation of the two clamping portions, so as to realize the installation and fixation of the luggage rack body 1.

[0061] It should be noted that when the clamping portion on the fixing portion is buckled with the clamping portion on the clamping portion, the inner diameters of the two clamping portions match the cross-sectional shape of the fixing seat 2 so that the fixing claw 3 can be clamped and fixed on the fixing seat 2 more firmly.

[0062] Optimally, the luggage rack body 1 further comprises a platform plate 12 which is detachably buckled on the supporting assembly and is used for placing items required to be carried when going out, so as to prevent items from falling off the luggage rack body 1.

[0063] It should be noted that the above-mentioned luggage rack body 1 is a frame structure, and there is a gap between two adjacent main rods 133. In order to prevent items whose volume is smaller than the gap between two adjacent main rods 133 from falling, the items can be placed on the platform plate 12 and then fixed with straps or other objects to make it more convenient to carry the items.

[0064] Optimally, the platform plate 12 comprises a supporting main plate 121 and a connecting plate 122, see Figure 2 ;in,

[0065] The supporting main board 121 is a rectangular plate-like structure. The supporting main board 121 is mounted on the supporting assembly. The connecting plate 122 is arranged at the top corner of the supporting main board 121. The end of the connecting plate 122 away from the supporting main board 121 is connected to the supporting rod. In this embodiment, the end of the connecting plate 122 away from the supporting main board 121 is connected to the supporting vertical rod 132, and the end of the connecting plate 122 away from the supporting main board 121 is arranged close to the two ends of the supporting vertical rod 132 to make the connection of the platform plate 12 more stable.

[0066] Optimally, a cavity is provided inside the supporting main board 121 to reduce the use of materials and lower the production cost of the automobile luggage rack. At the same time, the weight of the automobile luggage rack is reduced to reduce the impact of the automobile luggage rack on the fuel economy of the automobile.

[0067] Optimally, the above composite material is a mixture of PC plastic and ASA resin;

[0068] Although the composite material costs more than steel, it is lighter, which greatly reduces the weight of the entire car luggage rack. In this way, when the car is braking, starting, turning, etc., the inertia of the car luggage rack is low, the overall stability of the car is better, and to a certain extent, the fuel economy tends to be slightly reduced. After a long period of accumulation, the use cost of the car luggage rack is much lower than the production cost of the luggage rack in the prior art.
