Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically, to a vehicle body structural component fixing structure and a vehicle. Background Technology

[0002] Bolted connections are a common industrial manufacturing connection method. Bolts can connect two or more parts or components into a whole. For example, car roof racks and roof trims are usually bolted to the roof panel's drainage channels. The roof rack's function is to support the load, while the roof trim mainly serves to cover the roof welds and for decoration. Roof racks and roof trims usually have a large Dog House structure at the end (characterized by three-sided enclosure and one-sided opening). Bolts need to be installed on the Dog House structure first, and then passed through the pre-drilled holes in the roof panel for installation. The installation steps are relatively complicated, the process is troublesome, and the assembly efficiency is low. Utility Model Content

[0003] The problem this utility model aims to solve is: how to improve the assembly efficiency of vehicle body structural components.

[0004] This utility model provides a vehicle body structural component fixing structure for detachable connection between a first structural component and a second structural component. The second structural component is provided with a riveting component. The vehicle body structural component fixing structure includes: a Dog House structure disposed on the first structural component; and a fastener, the fastener including an annular body, a first fastening structure and a second fastening structure.

[0034] It should also be noted that the aforementioned Z-axis designation is only for the purpose of facilitating the description of this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on this utility model.

[0035] like Figures 1 to 6As shown, the vehicle body structural component fixing structure of this utility model embodiment is used for the detachable connection of the first structural component 1 and the second structural component 2. The second structural component 2 is provided with a riveting component 3. The vehicle body structural component fixing structure includes: a Dog House structure 4, which is disposed on the first structural component 1; and a fastener 5, which includes an annular body 51, a first fastening structure and a second fastening structure. The first fastening structure is disposed on the annular outer wall of the annular body 51 and is used to fasten with the Dog House structure 4. The second fastening structure is disposed on the annular inner wall of the annular body 51 and is used to fasten with the riveting component 3.

[0036] Specifically, the first structural component 1 can be a roof rack or roof trim, and the second structural component 2 can be a roof sheet metal, wherein the roof sheet metal is usually assembled using rivets, and the riveting component 3 can be the rivet.

[0037] As can be seen from the above, this utility model proposes a vehicle body structural component fixing structure, which aims to overcome the shortcomings in related technologies. Through the structural design of the Dog House structure 4 and the buckle 5, the first structural component 1 (roof rack or roof trim) can be quickly assembled onto the second structural component 2 (roof sheet metal), thereby improving the assembly efficiency of the vehicle body structural components.

[0038] A more detailed description of this includes: In this utility model, in conjunction with the appendix... Figure 1 To be continued Figure 6 As shown, before assembling the first structural component 1 (roof rack or roof trim) onto the second structural component 2 (roof sheet metal), the fastener 5 can be installed on the Dog House structure 4. This involves the first snap-fit ​​structure on the outer annular wall of the annular body 51 engaging with the Dog House structure 4, fixing the position of the fastener 5 relative to the Dog House structure 4. Then, the first structural component 1 can be moved to the assembly position of the second structural component 2, where the second structural component 2 on the inner annular wall of the annular body 51 engages with the rivet 3. Specifically, the rivet 3 can be inserted into the inner ring of the annular body 51 and engage with the second snap-fit ​​structure, fixing the position of the rivet 3 relative to the fastener 5, thereby assembling the first structural component 1 onto the second structural component 2. Compared to related technologies, this vehicle body structural component fixing structure allows the fastener 5 to be pre-installed on the Dog House structure 4, enabling the first structural component 1 to be quickly assembled onto the second structural component 2, thus improving the assembly efficiency of the vehicle body structural components.

[0039] It should be noted that the appendix Figure 1 To be continued Figure 6The first structural component 1 is a partial structural diagram of the roof rack, and the second structural component 2 is the roof sheet metal. The roof rack is installed in the roof drainage channel of the roof sheet metal.

[0040] It should be noted that the annular body 51 can be a regular annular structure or an irregular annular structure. Even if a notch is made in the annular body 51 so that the annular body 51 is C-shaped, it is still within the protection scope of this utility model.

[0041] Optionally, the Dog House structure 4 is provided with an installation port 41, and the inner wall of the installation port 41 is provided with a plurality of locking arms 42 spaced apart along the circumference. The locking member 5 is used to be installed in the installation port 41, and the locking member 5 is used to rotate relative to the installation port 41 by a set angle so that the first locking structure is locked with the locking arm 42.

[0042] In this embodiment, in conjunction with the appendix Figure 2 To be continued Figure 5 As shown, a mounting opening 41 is provided on the Dog House structure 4, wherein the mounting opening 41 can be in the vertical direction (see attached diagram). Figure 1 Or attached Figure 6 A through-hole structure is opened in the Z-axis direction, and multiple locking arms 42 are spaced apart on the circumferential inner wall of the mounting opening 41. Figure 3 There are three locking arms 42 in the middle. The ends of the locking arms 42 may be provided with hooks. The hooks of the multiple locking arms 42 are all set on the same side of the circumference of the mounting port 41. The fastener 5 can be inserted into the mounting port 41. After the fastener 5 is rotated at the mounting port 41 by a set angle, the first locking structure can abut and lock with the locking arm 42. For example, after the fastener 5 is rotated 60° clockwise, the first locking structure abuts and locks with the locking arm 42. At this time, the fastener 5 will not be able to continue to rotate clockwise. If you want to remove the fastener 5 from the mounting port 41, you only need to rotate it counterclockwise.

[0043] Optionally, the Dog House structure 4 includes side panels 43 and a bottom plate 44. The two side panels 43 are connected to the first structural member 1 at intervals, and the bottom plate 44 is connected between the two side panels 43. The mounting port 41 is provided on the bottom plate 44.

[0044] In this embodiment, in conjunction with the appendix Figure 3 As shown, the two side plates 43 of the Dog House structure 4 are connected at intervals to the end face of the first structural member 1 facing the second structural member 2. To enhance the structural strength of the side plates 43, stiffening ribs can be provided between the side plates 43 and the first structural member 1. The bottom plate 44 is connected between the ends of the two side plates 43 away from the first structural member 1, and the mounting opening 41 is provided on the bottom plate 44.

[0045] Optionally, the first snap-fit ​​structure includes a plurality of external claw structures 52, the same number as the snap-fit ​​arms 42. The plurality of external claw structures 52 are spaced apart and connected to the annular outer wall of the annular body 51. Each external claw structure 52 includes a first main body portion 521, which is connected to the annular outer wall of the annular body 51 and is used to abut against the snap-fit ​​arms 42. The end of the first main body portion 521 away from the annular body 51 is bent to form a second main body portion 522. The second main body portion 522 is used to abut against the end face of the base plate 44 away from the second structural member 2, so as to prevent the snap-fit ​​member 5 from falling off from the mounting opening 41 under the action of gravity.

[0046] In this embodiment, in conjunction with the appendix Figure 7 As shown, multiple external claw structures 52, the same number as the number of clamping arms 42, are spaced apart on the annular outer wall of the annular body 51. Each external claw structure 52 is used to engage with the corresponding clamping arm 42. Each external claw structure 52 includes a first main body portion 521, which can be connected to the annular body 51 by welding or integral molding. The upper part of the first main body portion 521 is bent to form a second main body portion 522, i.e., the first main body portion 521 and the second main body portion 522 form a structure resembling the number "7". (See attached diagram.) Figure 6 and attached Figure 7 As shown, the second main body 522 can overlap the upper surface of the base plate 44 (i.e., the surface of the base plate 44 facing the inside of the Dog House structure 4, with attachment) Figure 6 The surface on one side of the positive Z-axis direction can be used to prevent the buckle 5 from falling off the mounting port 41 under the action of gravity. The first main body 521 is used to engage with the buckle arm 42 after the buckle 5 is rotated to a set angle.

[0047] Optionally, the bottom plate 44 is provided with a stop protrusion 441 on the end face opposite to the second structural member 2. The stop protrusion 441 is used to abut against the second main body 522 to restrict the rotation of the buckle 5.

[0048] In this embodiment, in conjunction with the appendix Figure 10 As shown, a stop protrusion 441 is provided on the upper end face of the base plate 44 of the Dog House structure 4 (the end face opposite to the second main body 522). The stop protrusion 441 may be provided with a guide slope. The second main body 522 may be a plate-shaped structure with a concave surface. Thus, when the second main body 522 rotates on the base plate 44, the second main body 522 first contacts the guide slope of the stop protrusion 441, and then rotates under the guidance of the guide slope until the stop protrusion 441 falls into the concave part of the second main body 522. At the same time, the first main body 521 just abuts against the locking arm 42, thereby realizing the assembly of the fastener 5 on the Dog House structure 4.

[0049] Optionally, the locking arm 42 and the inner wall of the mounting port 41 form an anti-detachment locking groove 421, which is used to abut against the first main body 521 to restrict the rotation of the locking member 5.

[0050] In this embodiment, in conjunction with the appendix Figure 3 As shown, the locking arm 42 can be a rod-shaped structure that is inclinedly connected to the circumferential inner wall of the mounting port 41, or the end of the locking arm 42 can be bent to form a hook, so that the locking arm 42 can form an anti-detachment locking groove 421 with the circumferential inner wall of the mounting port 41. The anti-detachment locking groove 421 can abut against the first main body 521, that is, the first main body 521 can be rotatably inserted into the anti-detachment locking groove 421, so as to restrict the rotation of the fastener 5 through the insertion of the anti-detachment locking groove 421 and the first main body 521.

[0051] Optionally, the second snap-fit ​​structure is used to contact the rivet 3 and undergo elastic deformation to snap onto the shoulder 31 of the rivet 3.

[0052] In this embodiment, the riveting component can be a columnar structure with a shoulder 31, such as a rivet. The second snap-fit ​​structure can be an elastic snap-fit ​​structure. When the snap-fit ​​component 5 is connected to the riveting component 3, one end of the riveting component 3 with a shoulder 31 is used to insert into the annular body 51 of the snap-fit ​​component 5. The second snap-fit ​​structure will undergo elastic deformation during the process of passing through the shoulder 31, and the second snap-fit ​​structure will gradually recover its deformation and abut against the shoulder 31 to achieve snap-fit ​​engagement with the shoulder 31 of the riveting component 3.

[0053] Optionally, the second snap-fit ​​structure includes a plurality of inner claw structures 53, which are spaced apart and connected to the annular inner wall of the annular body 51. Each inner claw structure 53 includes a guide portion 531 and a limiting portion 532. The guide portion 531 is used to contact the riveting member 3 and undergo elastic deformation so that the limiting portion 532 abuts against the shoulder 31 of the riveting member 3.

[0054] In this embodiment, in conjunction with the appendix Figure 8 and attached Figure 9 As shown, multiple inner claw structures 53 are spaced apart on the annular inner wall of the annular body 51. Each inner claw structure 53 is used to engage with the riveting component 3. The inner claw structures 53 can be connected to the annular inner wall of the annular body 51 by welding or integral molding. (See attached diagram.) Figure 9As shown, the inner claw structure 53 can be a C-shaped structure formed by bending a rectangular plate structure. The inner claw structure 53 is inclined relative to the annular body 51. During the process of engaging with the rivet 3, part of the inner claw structure 53 first contacts the head of the rivet 3. This part is the guide part 531. As the fastener 5 continues to move downward, the guide part 531 disengages from the rivet 3, and then another part of the inner claw structure 53 abuts against the shoulder 31 of the rivet 3. This part is the limiting part 532. The limiting part 532 abuts against the shoulder 31 of the rivet 3, thereby engaging the fastener 5 onto the rivet 3.

[0055] In addition, this utility model also provides a vehicle, including a first structural member 1, a second structural member 2, and a vehicle body structural member fixing structure as described above.

[0056] Since the technical improvements and effects achieved by the vehicle are the same as those of the fixed structure of the vehicle body components, the technical effects of the vehicle will not be described in detail.

[0057] Optionally, the first structural component 1 is a roof rack or roof trim, and the second structural component 2 is a roof sheet metal.

[0058] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0059] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
