The following reference numerals E and F represent the roof of the luggage rack and the vehicle, respectively; the reference K and the reference M represent the outer plate and the inner plate of the roof, respectively.

The embodiment of the application provides an automobile luggage rack and an installation structure thereof, which are used for solving the problems of long installation time and complicated steps of the luggage rack caused by the fact that a tolerance regulator and a bolt at the bottom of the luggage rack are installed step by step in the installation process of the luggage rack in the related art.

Referring to fig. 3-10, an automobile luggage rack mounting structure, comprising:

the mounting seat 1 is provided with an outer plate connecting assembly 2 on the outer side, and a positive threaded hole 3 and a reverse threaded hole 4 which are coaxial are arranged in the mounting seat; the positive threaded hole 3 is positioned above the negative threaded hole 4 and has a diameter smaller than that of the negative threaded hole 4;

The reverse screw 5 is connected with the reverse screw hole 4 through a reverse screw thread at the outer side of the upper part of the reverse screw, and the lower part of the reverse screw is provided with an inner plate top surface supporting part;

A bolt 6 penetrating through the center of the counter-rotating member 5, and having an outer wall friction-held against an inner wall of the center of the counter-rotating member 5; the bolt 6 is provided with a positive thread connected with the positive threaded hole 3.

The automobile luggage rack mounting structure with the structure has the advantages that the tolerance regulator function is reserved, and meanwhile, a novel structure is provided for mounting the automobile luggage rack, so that in the mounting process, the mounting seat 1 and the anti-rotation piece 5 are assembled firstly, then the automobile luggage rack is placed from the top of the outer plate and connected with the outer plate, then the bolt 6 is placed from the inside of an automobile, and the bolt 6 is always positively rotated.

In the first stage, the bolt 6 is driven upwards from the inside of the vehicle body, the screw thread of the bolt 6 is firstly in friction against the inner wall of the counter-rotating piece 5, when the bolt 6 rotates forwards, the counter-rotating piece 5 is carried forward, the counter-rotating piece 5 rotates forwards to enable the counter-rotating piece 5 to move downwards by the cooperation of the counter-threaded hole 4 and the counter-screw thread, and when the counter-rotating piece 5 moves to the inner plate of the top cover, the second stage process is carried out. The counter-rotating element 5 is then still connected to the counter-threaded hole 4.

In the second stage, as the counter-rotating piece 5 moves downwards to a proper position, the position of the counter-rotating piece 5 is limited, the forward rotating bolt 6 is continued, and the bolt 6 moves relative to the counter-rotating piece 5, so that the counter-rotating piece moves upwards in the forward rotating process and is meshed with the forward threaded hole 3, so that tightening force is generated on the mounting seat 1; and continuing to positively rotate the bolt 6 until the bolt 6 and the mounting seat 1 are tightened to a specified moment of 8-9N meters, and finally completing the connection step.

The adjustment of the gap between the inner plate and the outer plate is completed when the connecting step is completed, the installation can be completed only by rotating the bolt 6 all the time in the process, the adjustment of the tolerance regulator is avoided through the integrated structural design, and then the step of installing the bolt is avoided, so that the installation time is saved, and the installation step is simplified. The development cost of the tolerance regulator is also saved.

Wherein, the principle of accomplishing the regulation lies in: in the first forward rotation process, the supporting part of the top surface of the inner plate of the reverse rotation piece 5 is supported against the inner plate of the top cover, meanwhile, the reverse rotation piece 5 is also connected with the reverse threaded hole 4, and at the moment, the outer plate connecting assembly 2 is fixedly connected with the outer plate of the top cover; that is, during the forward screwing of the bolt 6, the positions of the mounting seat 1 and the counter-rotating member 5 relative to the inner plate and the outer plate are unchanged, and the gap between the inner plate and the outer plate is adjusted after the counter-rotating member 5 is in place.

In some preferred embodiments, the structural form of the outer panel connection assembly 2 and the structural form of the mount 1 will be described in detail:

The mount 1 includes an exposed portion 100 and an extension portion 101 for passing through the outer panel via 7; the positive threaded hole 3 is located in the exposed portion 100 and the negative threaded hole 4 is located in the extended portion 101;

The outer plate connecting assembly 2 comprises an outer plate top surface pressing piece 201 and an outer plate bottom surface propping piece 200 which are vertically arranged at intervals; an outer panel top surface press-fit 201 is connected to the exposed portion 100 and is adapted to be parallel to the outer panel top surface; the bottom of the outer panel bottom surface supporting member 200 is connected to the outside of the extension portion 101, and the top is used to support the outer panel bottom surface.

The extension portion 101 may pass through the outer panel via hole 7, and then the upper and lower outer panel top surface press-fitting member 201 and the outer panel bottom surface top support member 200 are connected, thereby limiting the position of the mounting seat 1 up and down in the axial direction.

Wherein the extension 101 comprises a cylinder with an outer diameter smaller than the diameter of the outer plate via 7; the number of outer panel floor braces 200 is plural and divided over the entire body of the cylinder. The number of outer panel floor braces 200 is designed as desired. The multi-point support helps to distribute the pressure.

Further, the concrete structure of the outer panel bottom surface top support 200 is:

The outer plate bottom surface top support piece 200 comprises an elastic L-shaped connecting sheet 2000, a top support block is arranged at the top of the elastic L-shaped connecting sheet 2000, and the top surface of the top support block is attached to the outer plate bottom surface; the mounting seat 1 is made of metal, and the outer plate bottom surface top support 200 is made of plastic.

In this form, when the tightening force is too large, the angle between the elastic L-shaped connecting piece 2000 and the cylinder becomes large, and the position of the mount 1 is lowered.

The outer panel bottom surface top support 200 includes an elastic L-shaped connecting piece 2000; the top of the elastic L-shaped connecting sheet 2000 extends into the outer plate through hole 7, and is provided with a clamping step 2002, the outer side of the clamping step 2002 is provided with a transition inclined plane 2001 connected with the elastic L-shaped connecting sheet 2000, and the top is attached to the bottom surface of the outer plate. The corners of the elastic L-shaped connecting piece 2000 may be rounded to enhance the force transfer structure.

In this form, the snap-in step 2002 provides a jacking action as the top of the resilient L-shaped tab 2000 extends into the outer plate via 7, and such a structural design ensures that the radial spacing between the resilient L-shaped tab 2000 and the cylinder is limited, avoiding the problems associated with the previous form.

Of course, in either form, the manner in which the outer panel connection assembly 2 is connected to the roof outer panel is: the extension part 101 is sent into the outer plate through hole 7, and the elastic L-shaped connecting sheet 2000 is pressed and deformed by the outer plate through hole 7 in the sending process, so that the clamping step 2002 or the supporting block passes through the outer plate through hole 7, the shape is restored by the rear clamping step 2002 or the supporting block, and then the bottom surface of the outer plate is supported.

Wherein the design of the transition bevel 2001 facilitates the passage of the outer plate via 7.

In some preferred embodiments, the structure of the counter-rotating member 5 is described:

The anti-rotation piece 5 comprises a first cylinder 500 and a second cylinder 501, and the centers of the first cylinder 500 and the second cylinder 501 are respectively provided with a channel; the outer side of the first cylinder 500 is provided with a reverse thread; the second cylinder 501 is an inner plate top surface supporting part;

The diameter of the first cylinder 500 is smaller than the diameter of the second cylinder 501, and the diameter of the second cylinder 501 is larger than the diameter of the inner plate via hole 8; the diameter of the nut portion of the bolt 6 is larger than the diameter of the inner plate via hole 8.

The above structural design ensures that the counter-rotating member 5 does not risk falling out of the inner plate.

In the process of forward rotation of the bolts 6, in order to achieve the assembly moment of about 0.2 nm, the elastic L-shaped connecting sheet 2000 cannot be disabled or the outer plate of the top cover cannot be covered because of overlarge assembly moment. The following designs are available:

First, a plurality of friction blocks which are in friction against the bolts 6 are arranged in the channel of the second cylinder 501, and the plurality of friction blocks are distributed in the circumferential direction of the channel and extend in the axial direction; the friction block is made of elastic materials.

Secondly, a rubber sleeve 503 is coaxially and fixedly connected in a channel of the second cylinder 501, and an axially arranged circular arc rubber block 502 is arranged on the inner wall of a central hole of the rubber sleeve 503; the arc length of the inner arc of the circular arc rubber block 502 is smaller than the arc length of the outer arc. The rubber sleeve 503 and the second cylinder 501 and the first cylinder 500 are formed by injection molding.

When the assembly moment is overlarge, the friction force between the bolt 6 and the friction block or the circular arc rubber block 502 is exceeded, the bolt 6 and the anti-rotation piece 5 rotate relatively, and the force transmitted between the bolt 6 and the anti-rotation piece is not larger than the force affecting the top plate to lift the bag, so that the soft connection mode has the effect; so that the assembly moment to the counter-rotating member 5 is around 0.2 nm.

Referring to fig. 1 and 2, an automobile luggage rack, comprising:

a frame 9 mounted on the roof by a plurality of car roof rack mounting structures; one end of the framework 9 is inserted with an aluminum rod 10;

and a cover plate 11 which is engaged with the frame 9 and covers the frame 9, wherein a port at one end of the cover plate 11, which is in contact with the aluminum rod 10, is the same as the port of the aluminum rod 10 in shape and size. The cover plate 11 is provided with an electroplating decorative strip 14.

The waterproof foam also comprises a first waterproof foam 12 and a second waterproof foam 13, wherein the first waterproof foam 12 is arranged between the framework 9 and the top surface of the outer plate; the second waterproof foam 13 is used for being connected with the bottom surface of the outer plate; the first waterproof foam 12 and the second waterproof foam 13 improve the waterproof effect.

In addition, the outer panel top surface pressing member 201 is a part of the skeleton 9, and a reinforcing rib 15 is provided between the outer panel top surface pressing member 201 and the exposed portion 100; thereby reducing the structure and enhancing the connection strength between the mount 1 and the frame 9.

The automobile luggage rack mounting structure with the structure has the advantages that the tolerance regulator function is reserved, and meanwhile, a novel structure is provided for mounting the automobile luggage rack, so that in the mounting process, the mounting seat 1 and the anti-rotation piece 5 are assembled firstly, then the automobile luggage rack is placed from the top of the outer plate and connected with the outer plate, then the bolt 6 is placed from the inside of an automobile, and the bolt 6 is always positively rotated. In the first stage, the bolt 6 is driven upwards from the inside of the vehicle body, the screw thread of the bolt 6 is firstly in friction against the inner wall of the counter-rotating piece 5, when the bolt 6 rotates forwards, the counter-rotating piece 5 is carried forward, the counter-rotating piece 5 rotates forwards to enable the counter-rotating piece 5 to move downwards by the cooperation of the counter-threaded hole 4 and the counter-screw thread, and when the counter-rotating piece 5 moves to the inner plate of the top cover, the second stage process is carried out. The counter-rotating element 5 is then still connected to the counter-threaded hole 4. In the second stage, as the counter-rotating piece 5 moves downwards to a proper position, the position of the counter-rotating piece 5 is limited, the forward rotating bolt 6 is continued, and the bolt 6 moves relative to the counter-rotating piece 5, so that the counter-rotating piece moves upwards in the forward rotating process and is meshed with the forward threaded hole 3, so that tightening force is generated on the mounting seat 1; and continuing to positively rotate the bolt 6 until the bolt 6 and the mounting seat 1 are tightened to a specified moment of 8-9N meters, and finally completing the connection step. The adjustment of the gap between the inner plate and the outer plate is completed when the connecting step is completed, the installation can be completed only by rotating the bolt 6 all the time in the process, the adjustment of the tolerance regulator is avoided through the integrated structural design, and then the step of installing the bolt is avoided, so that the installation time is saved, and the installation step is simplified. The development cost of the tolerance regulator is also saved.

The invention overturns the assembly mode of the top cover luggage rack with the laser splice welding top cover type, and can save the development cost of the development height regulator by integrating the tolerance regulator function of the luggage rack onto the luggage rack body; meanwhile, because the left and right luggage rack assemblies are matched with 8 tolerance regulators, the assembly working hour is extremely challenged for the final assembly, the invention can save the working hour for installing 8 tolerance regulators, greatly quicken the installation efficiency, shorten the assembly working hour and bring great convenience and economic benefit.

One specific implementation is given below to describe the installation process in detail:

as shown in fig. 1, which is an assembly schematic diagram of the present patent assembly, an automobile luggage rack is mounted on a top cover assembly, fig. 2 is an explosion view of fig. 1, wherein an electroplating decorative strip 14 is assembled on a cover plate 11 through a clip, meanwhile, the cover plate 11 is clamped on a framework 9 in the z direction of a vehicle, then the tail end of the framework 9 and an aluminum rod 10 are assembled in the x direction of the vehicle, a reverse rotation piece 5 is mounted at the lower end of an extension part of a mounting seat 1, a first waterproof foam 12 is attached below the framework 9, water is prevented from entering an outer plate through hole 7, a bolt 6 locks the luggage rack from the inner side of the vehicle body, the assembly is realized, and the specific implementation process is as follows:

As shown in fig. 4, the second cylinder 501 of the anti-rotation member 5 and the rubber sleeve 503 are formed into a two-shot injection molding piece by double-sided injection molding, the anti-rotation nut thread of the first cylinder 500 is aligned with the anti-rotation hole 4, and pushed in and anti-rotated in the arrow direction, at this time, the anti-rotation member 5 is meshed with the anti-rotation hole 4 of the mounting seat 1 upwards and ascends, so as to finish the pre-assembly of the luggage rack.

As shown in fig. 5, the counter-rotating member 5 of the automobile luggage rack is aligned with the outer plate through hole 7 of the top cover and pushed downwards as shown by the arrow direction, it should be noted that the numerical value of the difference L between the inner plate and the outer plate of the top cover fluctuates due to the welding process accuracy, and the manufacturing tolerance is generally within ±3 mm.

As shown in fig. 6, when the automobile luggage rack is continuously pushed down, as shown in fig. 7, the outer panel bottom surface top supporting members 200 at two sides of the lower end of the mounting seat 1 are contacted with the outer panel bottom surface of the top cover, and then the outer panel top surface pressing members 201 are matched to complete the clamping connection with the outer panel, and meanwhile, the first waterproof foam 12 is compressed with the outer panel of the top cover, so that a waterproof effect is achieved. As shown in fig. 6, the counter-rotating member 5 is not bonded to the inner panel, and there is an indefinite height difference m.

When the bolt 6 is positively screwed from the inside of the vehicle body as shown in fig. 8, the bolt 6 passes through the inner plate through hole 8, the screw thread of the bolt 6 is meshed with the circular arc rubber block 502 of the rubber sleeve 503, the reverse screw 5 is positively rotated, and the reverse screw is reversely screwed with the reverse screw hole 4, so that the reverse screw 5 moves downwards until the reverse screw is attached to the inner plate due to the reverse screw, at the moment, the bolt 6 continuously rotates, the meshing force of the circular arc rubber block 502 and the screw thread of the bolt 6 exists, and the position of the circular arc rubber block 502 is not moved, so that the bolt 6 continuously moves upwards;

In addition, the arc rubber block 502 is in soft connection with the bolt 6, the assembly moment is about 0.2 nm, and the elastic L-shaped connecting sheet 2000 cannot be disabled or the outer plate of the top cover is covered because of overlarge assembly moment. In other words, when the moment is too large, the rubber block 502 and the bolt 6 slide relatively, so that the counter-rotating piece 5 is not driven to move continuously, the gap between the outer plate and the inner plate is enlarged, and a top bag is generated; meanwhile, the upward force of the elastic L-shaped connecting sheet 2000 of the plastic is completely attached to the outer plate of the top cover, so that the theoretical gap between the luggage rack and the outer plate of the top cover is ensured.

As shown in fig. 9, the bolt 6 moves up to the position of the positive threaded hole 3 at the upper end of the mounting seat 1, at this time, the forward rotation of the bolt 6 is continued until the bolt 6 rises to the prescribed moment of 8-9 nm, the electric tool is stopped, at this time, the bolt 6 transmits the force to the reverse rotation member 5 through locking the mounting seat 1 and transmits the force to the inner plate of the top cover, so that stable assembly is realized, assembly clearance and appearance are ensured, and as shown in fig. 10, the sectional view after assembly is completed.
