Description

Technical Field

[0001] The present invention belongs to the technical field of luggage placement devices, and particularly relates to a novel embedded composite luggage rack. Background Art

[0002] The luggage rack can be installed on the car roof. In addition to adding aesthetic beauty to the appearance, it also provides users with the functions of carrying goods and expansion. Most of the current luggage racks on the market are composed of two side beams located on the car roof. The two side beams cannot directly carry heavy objects. Two cross beams must be installed, and then the heavy objects are fixed on the cross beams. Some users will add a loading frame on the car roof. This kind of expansion also must be fixed on the luggage rack and cannot act directly on the car roof because the sheet metal strength of the car roof is weak and easy to deform, and at the same time, it also affects the opening of the sunroof. No matter which way of carrying goods, the luggage rack is fundamental and the basis for expansion.

[0003] Figure 1 introduces the structure of a conventional roof-mounted luggage rack, which is composed of two side beams. If a user needs to load items on the car roof, they need to first purchase a loading frame or a universal cross beam, as Figure 2 and Figure 3 shown. Such cross beams are mostly purchased from the aftermarket, and they do not fully match the luggage rack, so potential quality problems such as abnormal noise and wind noise may occur. When the customer does not use it, it needs to be removed and placed in a specific place, such as the trunk or other non-car-related positions, which adds the cumbersome process of installation and disassembly. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a novel embedded composite luggage rack, which solves the technical problems such as the inconvenience of storing the existing cross beams.

[0005] To solve the above problems, the technical solution of the present invention is: a novel embedded composite luggage rack, comprising:

[0006] Side beams, having at least two, are fixedly installed on the installation platform at intervals. Each side beam is provided with a storage groove, and the opposite ends of the storage groove are of a ramp structure, and threaded connection holes are provided on the ramp structure;

[0007] Cross beams, having at least two, the cross beam includes a fixed beam and two rotating beams. One ends of the two rotating beams are respectively hinged to the opposite ends of the fixed beam; when not in use, the cross beams are respectively and correspondingly embedded in the storage grooves. The other ends of the two rotating beams are respectively fixedly connected to the ramp structures at the opposite ends of the storage groove by cooperating with the threaded connection holes through installation screws; when in use, at least two cross beams are fixedly installed on at least two side beams at intervals, and the fixed beam and the two rotating beams forming the cross beam form a U-shaped structure, and the other ends of the two rotating beams are respectively fixed on different side beams through installation screws.

[0008] Preferably, when in use, at least two cross beams and at least two side beams form a frame structure.

[0009] Preferably, a relief groove is formed on the rotating beam, a perforation is formed on the inner wall of the relief groove, and the mounting screw is configured to pass through the perforation for fixed connection with the side beam.

[0010] Preferably, two cross beams and two side beams are provided.

[0011] Preferably, the openings of the receiving grooves of the two side beams face each other.

[0012] Preferably, when in use, the other end of the rotating beam is fixed to the bottom wall of the receiving groove by a mounting screw.

[0013] Preferably, the included angle between the rotating beam and the fixed beam ranges from 0° to 50°.

[0014] Preferably, when in use, the included angle between the rotating beam and the fixed beam is 50°.

Detailed implementation manners

[0032] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0033] Embodiment: As Figures 1 - 12 shown, this embodiment provides a new type of embedded composite luggage rack, including side beams 1 and cross beams 2. There are at least two side beams 1, which are fixedly installed on the mounting platform 3 at intervals. A receiving groove 11 is provided on each side beam 1. The opposite ends of the receiving groove 11 are ramp structures 12, and threaded connection holes are provided on the ramp structures 12; there are at least two cross beams 2. The cross beam 2 includes a fixed beam 21 and two rotating beams 22. One ends of the two rotating beams 22 are respectively hinged to the opposite ends of the fixed beam 21; when not in use, the cross beams 2 are respectively and correspondingly embedded in the receiving grooves 11. The other ends of the two rotating beams 22 are respectively fixedly connected to the ramp structures 12 at the opposite ends of the receiving groove 11 through the cooperation of mounting screws 23 and the threaded connection holes; when in use, at least two cross beams 2 are fixedly installed on at least two side beams 1 at intervals. The fixed beam 21 and the two rotating beams 22 that make up the cross beam 2 form a U-shaped structure, and the other ends of the two rotating beams 22 are respectively fixed on different side beams 1 through mounting screws 23.

[0034] With the above settings, in this embodiment, the cross beam 2 is integrated on the luggage rack. For example, Figure 4 , it can be unfolded when needed. For example, Figure 5 , the operation is simple. When not in use, it can be stored without the need for additional storage space. This structure also solves quality problems such as abnormal noise or wind noise that may be caused by poor matching of the cross beam 2 purchased in the aftermarket. After the cross beam 2 is placed in the storage groove 11, the cross beam 2 is integrated with the luggage rack, as shown in Figure 4 ; The end of the cross beam 2 has an angle-adjustable function. When in use, the cross beam 2 forms an inverted U-shaped structure, which can support the cross beam 2 and the heavy objects on it. Its component composition is as shown in Figure 11 . The rotating beam 22 can rotate a certain angle to adapt to the structural design of different installation positions or usage scenarios. Among them, the installation platform 3 can be the car roof.

[0035] Figure 6 After the cross beam 2 is taken out of the luggage rack, each rotating beam 22 is adjusted to the corresponding installation position in the direction of the arrow, and then the cross beam 2 is fixed to the luggage rack downward as shown in Figure 7 to complete the installation.

[0036] In a novel embedded composite luggage rack of this embodiment, when in use, at least two cross beams 2 and at least two side beams 1 form a frame structure. This setting improves the load-bearing stability.

[0037] In a novel embedded composite luggage rack of this embodiment, a relief groove 221 is provided on the rotating beam 22, and a perforation is provided on the inner wall of the relief groove 221 for the installation screw 23 to pass through to be fixedly connected to the side beam 1. This setting provides a shielding effect on the installation screw 23 and has a beautiful appearance. When disassembling and assembling the installation screw 23, a torque wrench 24 can be inserted into the relief groove 221 for disassembly.

[0038] In a novel embedded composite luggage rack of this embodiment, two cross beams 2 and two side beams 1 are provided. The structure is simple, the cost is low, and the load-bearing is stable.

[0039] In a novel embedded composite luggage rack of this embodiment, the side openings of the storage grooves 11 of the two side beams 1 face each other, and the cross beam 2 is placed in the storage groove 11 through the side openings. As shown in Figure 8 , it can be seen from the cross-sectional view that the cross beam 2 is located inside the luggage rack. From the outside, the two are almost integrated, which does not affect the overall appearance and does not cause other problems such as increased wind noise. The cross-sectional structure of the cross beam 2 can be adjusted according to strength. The cross-section of this embodiment is symmetric left and right, which is beneficial to error prevention during the manufacturing process.

[0040] The installation of the cross beam 2 and the luggage rack is as shown in Figure 8As shown in the figure, there is an installation screw 23 at each end of the cross beam 2. Corresponding to this, there is a ramp structure 12 at the front and rear ends of the luggage rack storage groove 11, and threaded connection holes are opened on the ramp structure 12. Using a torque wrench 24 to screw the installation screw 23 into the threaded connection holes of the ramp structure 12 for fixation, the cross beam 2 and the luggage rack can be combined into one.

[0041] In a novel embedded composite luggage rack of this embodiment, during use, the other end of the rotating beam 22 is fixed to the bottom wall of the storage groove 11 through the installation screw 23.

[0042] In a novel embedded composite luggage rack of this embodiment, the included angle range between the rotating beam 22 and the fixed beam 21 is 0° to 50°. Figure 12 It is a sectional view of the installation of the cross beam 2. There is an angle adjustment range of 0° to 50° between the rotating beam 22 and the fixed beam 21. When combined with the luggage rack as a whole, the rotating beam 22 needs to be flattened, that is, 0°. Rotating 50° can support the fixed beam 21 and fix it to the nut block 13 at the bottom of the luggage rack through the installation screw 23. The nut block 13 can be installed on the bottom surface of the luggage rack in advance.

[0043] In a novel embedded composite luggage rack of this embodiment, during use, the included angle between the rotating beam 22 and the fixed beam 21 is 50°. The 50° angle is the best structural angle obtained by fully considering the load-bearing stability of the cross beam 2 and through CAE analysis.

[0044] In a novel embedded composite luggage rack of this embodiment, the connection between the outer peripheral wall of the cross beam 2 and the outer peripheral wall of the side beam 1 is flush. When not in use, it is stored and combined with the luggage rack as a whole, with a beautiful shape.

[0045] In a novel embedded composite luggage rack of this embodiment, the cross beam 2 further includes a connection block 25. The inside of the fixed beam 21 is hollow. A part of the connection block 25 is fixedly inserted into the fixed beam 21 and fixedly connected through a fastening screw 26; the outer end of the connection block 25 is rotatably connected to the rotating beam 22. Specifically, the rotating beam 22 and the connection block 25 are rotatably installed together through a connection pin 27. It is convenient for the rotating beam 22 to rotate at an appropriate angle around the connection pin 27.

[0046] In a novel embedded composite luggage rack of this embodiment, the installation screw 23 is located in the relief groove 221 of the rotating beam 22. The opening of the relief groove 221 is covered by an upper cover 4. The upper cover 4 can be detachably clamped in the relief groove 221 by a conventional clamping structure, with a beautiful appearance. It can also adopt the following structure:

[0047] The upper cover 4 is snap-connected to the Y-shaped bracket 41 on the rotating beam 22. An elastically rotatable push switch 42 is arranged on the rotating beam 22. The push switch 42 is snap-connected to the upper cover 4. Pressing the push switch 42 can open the upper cover 4. Then, use a torque wrench 24 to disassemble the mounting screw 23. Finally, snap the upper cover 4 back onto the Y-shaped bracket inside the rotating beam 22 to cover the area of the mounting screw 23 and restore the complete appearance of the rotating beam 22.

[0048] In a novel embedded composite luggage rack of this embodiment, a gasket 5 is arranged between the rotating beam 22 and the bottom wall of the storage groove 11. The gasket 5 is used to buffer the pressure of the rotating beam 22 on the luggage rack.

[0049] The working principle is as follows: Flatten the rotating beam 22, and then the cross beam 2 can be fixed in the storage groove 11 inside the luggage rack through the mounting screw 23. At this time, the cross beam 2 is integrated with the luggage rack, with a beautiful appearance, no wind noise interference, reducing the user's additional purchase cost, and there is no need to find another place to store the cross beam 2. Rotate the rotating beam 22 to an angle of 50° with the fixed beam 21, that is, support the fixed beam 21, and fix it through the mounting screw 23 and the nut block 13 reserved in advance on the bottom surface of the luggage rack, thus completing the installation of the cross beam 2, and the operation is simple and convenient. The cross beam 2 is fixed by connecting through the mounting screw 23 at the bottom. The mounting screw 23 is hidden in the relief groove 221 of the rotating beam 22, and a torque wrench 24 can be used for disassembly and assembly operations.
