[0018] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. For a clearer understanding of the technical features, objectives, and effects of this invention, In the description of this invention, it should be understood that the terms "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.
[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0020] Firstly, such as Figures 1 to 8 As shown, an embodiment of the present invention provides a luggage rack mounting device, characterized in that it includes a luggage rack assembly 1 and a decorative cover. The decorative cover is disposed at the end of the luggage rack assembly 1. Two decorative covers are provided, namely a front decorative cover 2 and a rear decorative cover 3. The front decorative cover 2 and the rear decorative cover 3 are respectively connected to the two ends in the length direction of the luggage rack assembly 1.
[0021] The inner surface of the decorative cover is provided with a first limiting part 2222 and a snap-fit part 2323; the end of the luggage rack assembly 1 is provided with a luggage rack base, and the luggage rack base is provided with a second limiting part 121121 that cooperates with the first limiting part 22 and a mating part 124124 that cooperates with the snap-fit part 2323; wherein, the first limiting part 22 and the second limiting part 121 are inserted and engaged to restrict the movement of the decorative cover in the first direction, and the snap-fit part 23 and the mating part 124 are engaged and engaged to restrict the movement of the decorative cover in the second direction. The first direction and the second direction are different. The first direction is the Y direction (the width direction of the vehicle), and the second direction is the Z direction (the height direction of the vehicle).
[0022] Specifically, in this embodiment of the invention, the decorative cover, through its independently provided first limiting part 22 and snap-fit part 23 on its inner surface, respectively engages with the corresponding second limiting part 121 and mating part 124 on the base of the luggage rack assembly 1. This design ensures that the decorative cover is effectively mechanically constrained simultaneously in at least two different spatial directions during installation. This fundamentally overcomes the problems of looseness and abnormal noise caused by traditional single-point snap-fit or adhesive methods, ensuring a stable connection between the decorative cover and the luggage rack assembly 1, and precisely controlling the assembly gap, thereby improving the overall rigidity, durability, and aesthetic refinement of the assembly components.
[0023] The decorative cover is integrally injection molded, and its connection with the base is entirely achieved through the aforementioned plug-in and snap-fit structure, requiring no additional fasteners or auxiliary tools for locking. During installation, the operator only needs to align it and apply a downward force to complete the limiting and fixing in multiple directions at once. This simple operation of pressing after alignment greatly simplifies the assembly process, reduces the skill requirements for operators, significantly reduces assembly time and labor intensity, and helps improve production line cycle time and assembly consistency.
[0024] By integrating the first limiting part 22 and the snap-fit part 23 onto the inner surface of the integrally injection-molded decorative cover, and integrating the corresponding mating structure onto the luggage rack base, the additional standard parts such as independent buckles, clips, and screws required in traditional connection methods are eliminated. This not only reduces the types and quantities of materials, lowering procurement and management costs, but also avoids the risk of missing or incorrectly installed small parts. At the same time, the simple and reliable mechanical interlocking structure reduces reliance on high-precision positioning fixtures, lowering production and maintenance costs.
[0025] In a preferred embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the first limiting part 2222 is a wedge-shaped insert, and the second limiting part 121121 is a wedge-shaped groove adapted to the shape of the wedge-shaped insert. A first contact surface is provided on the first limiting part 22, and a second contact surface is provided on the second limiting part 121. The first contact surface and the second contact surface are in contact. The first contact surface is an inclined plane, and there is an angle between the inclined extension direction of the first contact surface and the second direction, and the angle is an acute angle.
[0026] Furthermore, the decorative cover is provided with two first limiting parts 22, which are arranged opposite to each other along the width direction of the decorative cover. The width direction of the decorative cover is parallel to the first direction. The first contact surfaces of the two first limiting parts 22 are V-shaped. The distance between the upper ends of the first contact surfaces of the two first limiting parts 22 is greater than the distance between the lower ends of the first contact surfaces of the two first limiting parts 22. Specifically, the upper ends of the two first contact surfaces are far apart from each other, while the lower ends are close together. Correspondingly, the luggage rack base is provided with two second limiting parts 121. The two first limiting parts 22 are located between the two second limiting parts 121 during assembly, and each first limiting part 22 cooperates with one of the second limiting parts 121. The decorative cover includes two first outer side walls, which are arranged opposite to each other along the width direction of the decorative cover. The two first limiting parts 22 are located between the two first outer side walls, and each first limiting part 22 is fixedly connected to the inner wall surface of one of the first outer side walls. A groove is formed between the first limiting part 22 and the first outer side wall to allow the second limiting part 121 to be inserted. This groove is used during assembly to accommodate and allow the corresponding part of the second limiting part 121 to be inserted. A third contact surface is also provided on the second limiting part 121, which fits against the first outer side wall. The third contact surface is an inclined plane, and it is V-shapedly distributed with the second contact surface. The upper end of the third contact surface connects to the upper end of the second contact surface, forming a pointed structure at the upper end of the second limiting part 121. The groove formed on the decorative cover is a V-shaped groove.
[0027] This structure, through the engagement of double-inclined contact surfaces arranged in a "V" shape, achieves bidirectional abutment and restraint in the width direction of the decorative cover, effectively preventing its movement in this direction and improving the structural stability and rigidity after assembly. The recessed design of the groove and the embedded second restraining part 121 increases the contact area and improves the torsional and deformation resistance of the connection part. At the same time, the inclined contact surfaces and the pointed upper structure act as guides, allowing the decorative cover to be aligned and inserted more smoothly during installation, reducing assembly difficulty and ensuring the uniformity of the final assembly gap and the exquisite appearance.
[0028] In a preferred embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the snap-fit part 23 is specifically implemented as a snap-fit seat disposed on the inner surface of the decorative cover, and the mating part 124 is specifically implemented as a snap-fit groove formed on the surface of the luggage rack base. The first limiting part 22 and the snap-fit seat are both disposed at the end of the inner surface of the decorative cover, and correspondingly, the second limiting part 121 and the snap-fit groove are disposed at both ends and the left and right sides of the luggage rack base. During assembly, the snap-fit seat is embedded in the corresponding snap-fit groove. By using the circumferential wrapping and constraint of the snap-fit groove on the snap-fit seat, the displacement of the decorative cover in the direction perpendicular to the snap-fit direction can be effectively limited, and the tendency of the decorative cover to accidentally fall out of the snap-fit groove due to the elastic deformation of the material can be suppressed, thereby significantly enhancing the long-term stability and reliability of the connection point.
[0029] Furthermore, such as Figure 6 As shown, two card holders are provided, respectively arranged on the two first outer side walls of the decorative cover. Correspondingly, two slots are also provided on the luggage rack base. In the assembled state, each card holder is precisely embedded in one slot. This symmetrically arranged double-point snap-fit structure, combined with the limiting structure formed by the aforementioned double wedge inserts, forms a stable and balanced constraint couple on the left and right sides (i.e., the width direction) of the decorative cover, together constituting a limiting structure that effectively constrains the decorative cover in multiple spatial directions, ensuring the overall rigidity and assembly accuracy of the connection between the decorative cover and the luggage rack base.
[0030] In embodiments of the present invention, such as Figures 1 to 6 As shown, the luggage rack assembly 1 includes a luggage rack body 11 and luggage rack bases. The luggage rack body 11 is an internally hollow structure made of high-strength aluminum profile through a 3D bending process. Two luggage rack bases are provided, and the two bases are fixed to both ends of the luggage rack body 11 along its length direction using fasteners. The length direction of the luggage rack body 11 is perpendicular to a first direction and a second direction. Each luggage rack base includes a mounting body 126, with a retainer 125 extending from one end of the mounting body 126 facing the luggage rack body 11. During assembly, the retainer 125 is inserted into the end cavity of the luggage rack body 11. A shoulder 122 is formed at the connection between the retainer 125 and the mounting body 126, and the shoulder 122 contacts the end face of the luggage rack body 11. When the retainer 125 is fully inserted, the shoulder 122 contacts the end face of the luggage rack body 11, the retainer 125 is fully inserted, and the mounting body 126 is located outside the luggage rack body 11 and flush with it.
[0031] The tight fit between the outer contour of the neck 125 and the inner contour of the luggage rack body 11 effectively limits their relative position and surface difference, ensuring that the base and the body are aligned. At the same time, the direct contact between the shoulder 122 and the end face of the luggage rack body 11 precisely controls and limits the assembly gap between the two in the length direction of the luggage rack body 11, avoiding assembly loosening or misalignment caused by accumulated tolerances.
[0032] After completing the above-mentioned insertion and positioning, multiple (e.g., two) self-tapping screws 15 are passed through the pre-drilled screw holes at the bottom of the luggage rack body 11 and finally screwed into and secured to the pre-fabricated BOSS post (reinforcing post) inside the neck 125. This connection method, which combines insertion and screw fastening, not only combines the advantages of quick and accurate insertion positioning, but also provides strong axial locking force and shear resistance through the screws, making the connection between the luggage rack base and the luggage rack body 11 extremely stable and reliable, effectively withstanding various loads during the use of the luggage rack. Moreover, this structure separates and integrates the functions of precise positioning and final locking onto the base, making the assembly process clear and simple: first insert the positioning screw, then tighten it. This reduces the technical requirements for operators and improves assembly efficiency and production consistency.
[0033] Furthermore, such as Figure 4 As shown, the decorative cover has a latch 21 at one end facing the luggage rack body 11. The latch 21 is inserted into the gap between the luggage rack body 11 and the neck 125. The latch 21 is fixedly set at one end of the decorative cover along its length. Preferably, multiple latches 21 are provided, and all latches 21 are arranged sequentially along the width direction of the decorative cover. The luggage rack decorative cover is inserted into the notch on the luggage rack body 11 and the neck 125 through the latch 21 at its end, restricting the upward movement of the end of the decorative cover and controlling the surface difference with the luggage rack body 11. The width of the two edges of the latch 21 limits the surface difference with the luggage rack body 11 in the Y direction.
[0034] When multiple latches 21 are inserted into the gap between the luggage rack body 11 and the neck 125, their ends or upper surfaces abut against the inner wall of the luggage rack body 11 or the corresponding structure on the neck 125, effectively suppressing the tendency of the decorative cover end to warp in the vertical direction. This directly ensures that the height difference (i.e., surface difference) between the decorative cover end and adjacent parts of the luggage rack body 11 is strictly controlled within the design range, ensuring a flat and continuous appearance. Each latch 21 has two side edges of a defined width. In the assembled state, these side edges fit tightly with the two side walls of the gap. By precisely designing the width of the latch 21 and the width of the gap, the side edges of the latch 21 can be used to precisely limit the decorative cover in the width direction. This effectively prevents the decorative cover from shifting left and right in the horizontal plane, ensuring its alignment with the luggage rack body 11 in the width direction and the uniformity of the seam.
[0035] like Figure 7 As shown, a U-shaped insert 24 is provided on the top back of the decorative cover; a vertical rib is provided on the mounting base body 126, and the U-shaped insert 24 cooperates with the vertical rib to limit the gap between the decorative cover and the luggage rack body 11.
[0036] In embodiments of the present invention, such as Figures 1 to 6 and Figure 8As shown, the luggage rack assembly 1 also includes a luggage rack pad 14, which is located at the bottom of the luggage rack body 11. One of its main functions is to provide sealing and cushioning. A rib 141 is provided around the upper surface of the luggage rack pad 14; a brim 123 is provided at the bottom edge of the luggage rack base, and a second limiting part 121 is fixedly mounted on the brim 123. The rib 141 cooperates with the lower part of the brim 123. The brim 123 is fixedly located at the outer edge of the mounting base body 126, forming an L-shaped cross-sectional profile. The rib 141, which surrounds the luggage rack pad 14, is designed in size and shape to fit snugly into the first receiving groove formed by the brim 123 and the bottom surface of the mounting base body 126. Simultaneously, a recessed second receiving groove is provided at a corresponding position on the bottom surface of the luggage rack body 11. In the final assembled state, a portion of the rib 141 is simultaneously embedded in both the first and second receiving grooves.
[0037] At the bottom edge of the roof rack base, except for the side connected to the end of the roof rack body 11, upward-protruding visors 123 extend in three directions: the other side away from the roof rack body 11 and the left and right sides. Through the cooperation of the rib 141, the visor 123, and the receiving groove on the roof rack body 11, a continuous, circumferential physical barrier structure is formed at the installation boundary between the roof rack assembly 1 and the vehicle roof 7. This "dam" formed by the rib 141 effectively blocks and diverts liquids that may seep from the outside (such as rainwater) along the edge of the roof rack base or the joints of the decorative cover, preventing them from directly flowing into the internal cavity or sheet metal layers of the vehicle roof 7. Simultaneously, the embedded cooperation of the rib 141 with the first and second receiving grooves not only provides a sealing function but also constitutes a mechanical interlock between the roof rack gasket 14 and the roof rack base and roof rack body 11 in the vertical and horizontal directions. This enhances the structural integrity of the bottom component of the luggage rack assembly 1, reduces the relative displacement between parts that may occur due to vibration, and ensures stability during long-term use.
[0038] As previously stated, the bottom surface of the first outer wall of the decorative cover will adhere to the upper surface of the luggage rack pad 14 after assembly. This mating surface, together with the sealing structure of the reinforcing dam 141-brim 123, forms a continuous sealing structure from the side to the bottom surface, surrounding the luggage rack mounting area, significantly improving the dustproof and waterproof performance of the entire mounting area.
[0039] Furthermore, such as Figure 5As shown, the periphery of the roof rack pad 14 is also bent downwards continuously, forming a lip that extends in a circle. The design of this lip is based on its interference fit with the surrounding body structural components. Specifically, after the roof rack assembly 1 is finally installed on the body, this downwardly bent lip will contact the corresponding areas or structures of the lower top edge beam outer trim 6 and the outer panel of the body roof 7, forming a certain degree of elastic compression. This interference design ensures that the lip is always in a slightly compressed or fitted state after installation. The dam 141 mainly blocks liquid seepage from the joints of the roof rack assembly 1 body components, while this downwardly bent lip focuses on sealing the assembly gap between the outer edge of the roof rack pad 14 and the body roof 7 and the top edge beam trim.
[0040] In embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 8 As shown, the fixing and connection method between the luggage rack pad 14 and other components of the luggage rack assembly 1 has been specifically optimized, achieving quick, reliable assembly without the need for additional fasteners. Specifically, multiple first buckles 142 are integrally formed on the upper surface of the luggage rack pad 14, which are preferably mushroom-shaped buckles. Correspondingly, first locking holes matching the position and shape of these mushroom-shaped buckles are provided at the bottom of the luggage rack base. The first locking holes can be irregularly shaped holes. At the same time, second locking holes are provided on the edges or inner sides of the bottom of the luggage rack body 11, which can be specifically represented as Ω-shaped grooves or arched grooves.
[0041] During assembly, the operator places the luggage rack pad 14 in a preset position, aligning the first buckle 142 on its upper surface with and engaging it into the irregular hole (i.e., the first locking hole) at the bottom of the luggage rack base and the Ω-shaped slots (i.e., the second locking holes) on both sides of the luggage rack body 11. After the head of the first buckle 142 passes through the hole or slot, it achieves a secure engagement by utilizing its elastic recovery and the barb or interference structure formed with the edge of the hole or slot.
[0042] In embodiments of the present invention, such as Figures 1 to 3 As shown, a welding bracket 71 is provided on the roof 7 of the vehicle body, and the luggage rack assembly 1 is fixedly connected to the welding bracket 71 by fasteners.
[0043] The roof rack assembly 1 is fastened to a pre-installed welded bracket 71 on the roof 7 of the vehicle body via six connectors, preferably hexagonal flange nuts, in the vertical direction (Z direction). Each of the two roof rack bases has two mounting points, i.e., each has mounting holes through which the nuts pass.
[0044] Given that the luggage rack base is typically injection molded, its dimensional stability and positional accuracy are higher than those of the aluminum luggage rack body 11, which is formed by 3D bending. Therefore, the more dimensionally stable base is used as the primary positioning reference. Specifically, the mounting holes on the front base 12 near the front end of the luggage rack body 11 are defined as primary positioning holes, and the mounting holes on the rear base 13 near the rear end of the luggage rack body 11 are defined as secondary positioning holes. Corresponding through holes or vias are provided on the luggage rack body 11 to accommodate the passage of connecting parts. By utilizing the higher dimensional accuracy of the injection-molded base to undertake the main positioning function, the dimensional deviations or cumulative errors that may occur in the luggage rack body 11 due to the processing technology can be effectively compensated for and absorbed. This allows for the unique determination of the precise position and orientation of the luggage rack assembly 1 on the vehicle body, ensuring consistency and installation reliability in batch assembly and laying the foundation for overall assembly accuracy from the source.
[0045] The luggage rack mounting device described above has the following advantages: 1. The front and rear decorative covers 3 of this invention have wedge-shaped inserts on both sides inside, which, when assembled with wedge-shaped grooves on the front and rear bases 13 of the luggage rack, form left and right limits; the decorative covers of the luggage rack have card seats on both sides inside, which engage with the arched card slots on the luggage rack base, forming upper and lower limits. These structures, along with the structures that limit the front and rear directions, allow for more precise assembly between the front and rear decorative covers 3, the front and rear bases 13, and the luggage rack body 11, making the front and rear end covers of the luggage rack more securely assembled, effectively reducing assembly gaps, and making the luggage rack more aesthetically pleasing and refined.
[0046] 2. The rib 141 on the roof rack pad 14, in conjunction with the visor 123 on the edges of the front and rear base 13 of the roof rack and the arched groove of the roof rack body 11, can prevent water from flowing from the gaps in the roof rack assembly 1 and the bottom edge of the roof rack end cap into the vehicle frame cavity. This ensures the sealing of the connection joint and avoids the risk of water leakage. 3. The luggage rack body 11 and the luggage rack base are assembled with 4 self-tapping screws 15. The luggage rack rubber pad 14 is connected to the luggage rack base and body by its own structure. The luggage rack decorative cover and luggage rack bolt plug 4 are injection molded as one piece. The connection between the various parts is simple, without the need for buckles, clips and other auxiliary standard parts for assembly. The assembly is simple and improves the assembly efficiency of the luggage rack.
[0047] Secondly, embodiments of the present invention also provide a vehicle including a luggage rack mounting device with the above-described structure. This luggage rack mounting device can be referred to... Figures 1 to 8 Further details will not be elaborated here. Since the vehicle of the present invention includes the luggage rack mounting device described in the above embodiments, it possesses all the advantages of the aforementioned luggage rack mounting device.
[0048] Thirdly, embodiments of the present invention also provide a method for assembling a luggage rack, comprising the following steps: The luggage rack assembly 1 and the decorative cover with the above structure are provided. The inner surface of the decorative cover is provided with a first limiting part 22 and a snap-fit part 23. The end of the luggage rack assembly 1 is provided with a luggage rack base. The luggage rack base is provided with a second limiting part 121 and a mating part 124. The decorative cover is installed to the end of the luggage rack assembly 1, so that the first limiting part 22 on the decorative cover is engaged with the second limiting part 121 on the luggage rack base to restrict the movement of the decorative cover in the first direction; at the same time, the snap-fit part 23 on the decorative cover is engaged with the mating part 124 on the luggage rack base to restrict the movement of the decorative cover in the second direction; the first direction and the second direction are different.
[0049] The step of installing the decorative cover also includes inserting the tab 21 at the end of the decorative cover into the gap between the luggage rack body 11 and the neck 125 of the luggage rack base of the luggage rack assembly 1.
[0050] The installation of the decorative cover also includes: aligning the U-shaped insert 24 on the top back of the decorative cover with the vertical rib in the luggage rack base frame structure.
[0051] Specifically, when installing the decorative cover, firstly, the latch 21 at the end of the decorative cover is inserted into the gap formed between the end of the luggage rack body 11 and the latch 125 of the luggage rack base. In this step, the end or upper surface of the latch 21 contacts the relevant structure, initially limiting the upward displacement of the end of the decorative cover in the vertical direction (Z direction) and beginning to control the appearance surface difference between it and the luggage rack body 11. At the same time, by relying on the width dimensions of the two sides of the latch 21 and the width of the gap, the decorative cover is initially positioned in the horizontal direction (Y direction), controlling the surface difference in the Y direction.
[0052] Then, press down on the decorative cover, causing the retaining plates on both sides of its inner surface to elastically deform and engage with the corresponding arched slots on both sides of the luggage rack base. This action achieves primary fixation of the decorative cover in the Z-direction, firmly limiting its possibility of detachment.
[0053] During the pressing process, the wedge-shaped inserts located on the inner surface of the decorative cover near the card slot are simultaneously inserted into the corresponding wedge-shaped grooves at the front end of the luggage rack base. The wedge-shaped inserts fit tightly against the beveled surfaces of the wedge-shaped grooves, providing anti-shifting capability in the horizontal (Y-direction).
[0054] In addition, the U-shaped insert 24 on the back of the top of the decorative cover cooperates with the vertical rib in the luggage rack base frame structure to restrict the movement of the decorative cover in the length direction (X direction) of the luggage rack.
[0055] Before providing the luggage rack assembly 1, there is also a step of assembling the luggage rack assembly 1, the specific operation of which is as follows: The luggage rack base is fixed to the end of the luggage rack body 11 with fasteners; Install the luggage rack pad 14 to the bottom of the luggage rack body 11.
[0056] The steps for installing the luggage rack pad 14 to the bottom of the luggage rack body 11 include: The first buckle 142 on the upper surface of the luggage rack pad 14 is inserted into the first buckle hole at the bottom of the luggage rack base and the second buckle holes on both sides of the luggage rack body 11; The rib 141 on the periphery of the upper surface of the luggage rack pad 14 is located below the brim 123 at the bottom edge of the luggage rack base.
