Description

Technical Field

[0001] This application relates to the technical field of automotive parts assembly, specifically to a connecting component and a fixing component. Background Technology

[0002] Car roofs are often equipped with racks for loading luggage or decorating the car body. In the current technology, roof racks are usually installed in the grooves between the roof and the two side panels of the car body. These grooves are usually called rain gutters and are mainly used to guide rainwater in rainy weather. They are also often used to install roof accessories such as roof racks, which can achieve the effect of non-destructive installation.

[0003] However, with the increasing prevalence of panoramic sunroofs in the automotive industry, the space in roof gutters is constantly shrinking. This has resulted in many cars having insufficient space in their roof gutters to accommodate roof racks. Therefore, the market urgently needs a product that allows for the seamless installation of roof accessories onto the roof. This application provides a connecting component and a vehicle body component for securing roof racks and other roof accessories to the roof gutter, thereby solving the aforementioned technical problem.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the invention. Similarly, the following embodiments are only some, not all, embodiments of the present invention, and all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] It should be noted that the terms "comprising" and "having," and any variations thereof, in the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0026] Currently, adhesive bonding is a common method for connecting roof racks to vehicle roofs. The applicant's research found that using 3M adhesive to attach the bottom of the roof rack to the roof is a convenient method. However, roof racks installed in this way have limited load-bearing capacity and are only suitable for decorative purposes, not for mounting luggage, as this poses a safety hazard. The applicant further discovered that by drilling holes in the roof gutter and pre-embedding nuts inside, the roof rack can be secured to the roof with bolts, preventing damage to the roof surface. Additionally, by welding metal brackets with bolts or nuts to the roof gutter, the roof rack can be fixed to the metal brackets with nuts or bolts, allowing for a secure and damage-free installation on the roof. However, further research by the applicant revealed that both methods of mounting roof racks on the vehicle roof require a certain amount of space in the roof rain gutters. With the increasing prevalence of panoramic sunroofs in the automotive industry, the space available for roof rain gutters is constantly shrinking or even being eliminated, which to some extent limits the use of these roof rack mounting methods on certain vehicles. Therefore, this application provides a vehicle body component 10 to further address the aforementioned technical problems.

[0027] Please see Figure 1 , Figure 1This is a schematic diagram of a vehicle body equipped with a vehicle body assembly 10 according to an embodiment of this application. The vehicle body assembly 10 in this embodiment includes, but is not limited to, a roof beam 102, a crossbeam 103, and a connecting assembly 20. The end of the crossbeam 103 is recessed to form a vehicle body groove 101. The connecting assembly 20 can be fixed to the vehicle body groove 101 and is fixedly connected to the roof beam 102 and / or the crossbeam 103. Specifically, the roof beam 102 can be located on the top of the vehicle, and the crossbeam 103 can be located on both sides of the vehicle. The end of the crossbeam 103 facing the middle of the vehicle body can be recessed to form the vehicle body groove 101, and the roof beam 102 can cover the vehicle body groove 101. The connecting assembly 20 can be fixed to the vehicle body groove 101 and fixedly connected to the top of the roof beam 102 and / or the crossbeam 103, so that external brackets and other accessories can be installed on the connecting assembly 20. For example, the vehicle crossbeam 103 can be a side panel of the vehicle body, the vehicle roof beam 102 can be the top of the vehicle body, and the vehicle body groove 101 can be a rain groove between the side panel and the top of the vehicle body. The connecting component 20 can be disposed in the rain groove and fixed to the side panel and the top of the vehicle body respectively. Thus, the roof rack can be fixed to the roof by means of the connecting component 20 to achieve non-destructive installation of the roof rack on the roof. In other embodiments of this application, the vehicle roof beam 102 and the vehicle crossbeam 103 can also be beams disposed on the side panel and the top of the vehicle body respectively, and the connecting component 20 can be fixed to the roof by means of the vehicle roof beam 102 and / or the vehicle crossbeam 103. No specific limitation is made here.

[0028] The vehicle body assembly 10 provided in this application embodiment can utilize the cooperation structure of the connecting assembly 20 with the vehicle body groove 101, the roof beam 102 and the vehicle crossbeam 103 to place the connecting assembly 20 in the vehicle body groove 101 and fix it to the top of the roof beam 102 and / or the vehicle crossbeam 103, thereby enabling external roof accessories to be fixed to the roof beam 102 and / or the vehicle crossbeam 103 by means of the connecting assembly 20, so as to achieve non-destructive installation of external roof accessories on the vehicle roof.

[0029] Further, please refer to Figure 2 , Figure 2This is a three-dimensional structural diagram of the vehicle body component 10 in one embodiment of this application. Optionally, in this embodiment, the connecting assembly 20 includes, but is not limited to, a first connector 200, a second connector 300, a third connector 400, and a fourth connector 500; wherein, the first connector 200 may be disposed in the body groove 101 and fixed on the surface formed by the body groove 101; the ends of the second connector 300 and the third connector 400 near the body groove 101 may engage with the first connector 200 in the body groove 101, so that the second connector 300 and the third connector 400 are detachably fixed in the body groove 101; the fourth connector 500 may be disposed on the roof beam 102 and / or the cross beam 103, and connected to the end of the second connector 300 and the third connector 400 opposite to the body groove 101, so that the fourth connector 500 can be fixed on the roof beam 102 and / or the cross beam 103 with the cooperation of the second connector 300 and the third connector 400.

[0030] Specifically, the body groove 101 can be formed with a first surface 110, the roof beam 102 can be formed with a second surface 120, and the crossbeam 103 can be formed with a third surface 130. The end of the crossbeam 103 can be recessed to form the body groove 101. The first surface 110 can be the upper surface of the bottom of the body groove 101, the second surface 120 can be the upper surface of the roof beam 102, and the third surface 130 can be the upper surface of the crossbeam 103 that is not recessed to form the body groove 101. The roof beam 102 can cover the body groove 101 and there is a gap between the roof beam 102 and the body groove 101. The first connector 200 can be fixed to the first surface 110 and engage with the second connector 300 and the third connector 400 in the body groove 101. Then, the second connector 300 and the third connector 400 can engage with the fourth connector 500 to fix the fourth connector 500 to the roof beam 102 and / or the cross beam 103.

[0031] Furthermore, please refer to the following: Figure 3 and Figure 4 , Figure 3 yes Figure 2 A side view of the vehicle body component 10 in the embodiment. Figure 4 yes Figure 2A schematic diagram of the cross-sectional structure of the vehicle body assembly 10 along AA in the embodiment. Optionally, in this embodiment, the first connector 200 has a first fixing part 201 and a first connecting part 202 at both ends, the second connector 300 has a second connecting part 301 and a third connecting part 302 at both ends, the third connector 400 has a fourth connecting part 401 and a fifth connecting part 402 at both ends, the fourth connector 500 has a second fixing part 501 and a third fixing part 502 at both ends, and a sixth connecting part 503 is formed between the second fixing part 501 and the third fixing part 502.

[0032] The first fixing part 201 of the first connector 200 can be fixed to the first surface 110, and the first connecting part 202 can be disposed in the body groove 101; the second connecting part 301 of the second connector 300 and the fourth connecting part 401 of the third connector 400 can engage with the first connecting part 202 in the body groove 101, so that the second connector 300 and the third connector 400 are detachably fixed in the body groove 101; the third connecting part 302 and the fifth connecting part 402 are disposed on the back of the roof beam 102. On one side away from the body groove 101; the second fixing part 501 of the fourth connector 500 abuts against the second surface 120, and / or the third fixing part 502 abuts against the third surface 130; the sixth connecting part 503 of the fourth connector 500 is connected to the third connecting part 302 and the fifth connecting part 402, and then the sixth connecting part 503 cooperates with the third connecting part 302 and the fifth connecting part 402 to fix the second fixing part 501 to the roof beam 102, and / or fix the third fixing part 502 to the cross beam 103.

[0033] Furthermore, the connecting assembly 20 may also include a locking member 600, which can cooperate with the third connecting portion 302, the fifth connecting portion 402, and the sixth connecting portion 503 to fix the second fixing portion 501 on the second surface 120, and / or fix the third fixing portion 502 on the third surface 130. The fifth connecting portion 402 and the sixth connecting portion 503 may have through holes, and the third connecting portion 302 may have a corresponding nut. The locking member 600 can pass through the through holes of the fifth connecting portion 402 and the sixth connecting portion 503, thereby being threadedly connected to the third connecting portion 302. The locking member 600 can then cooperate with the third connecting portion 302 and the fifth connecting portion 402 to abut against the sixth connecting portion 503, thereby fixing the second fixing portion 501 formed at the end of the sixth connecting portion 503 to the second surface 120, and / or fixing the third fixing portion 502 formed at the end of the sixth connecting portion 503 to the third surface 130.

[0034] Specifically, in this embodiment, the fourth connecting member 500 can be a bracket, the second fixing part 501 and the third fixing part 502 are respectively the two side walls of the bracket, the sixth connecting part 503 can be a top wall formed between the two side walls and respectively connected to the two side walls, the top wall can form a through hole that can accommodate the locking member 600, the third connecting part 302 and the fifth connecting part 402 can be provided with corresponding through holes, and the fifth connecting part 402 can cover the third connecting part 302, the bottom of the third connecting part 302 can also be provided with a bolt, the locking member 600 can be a screw corresponding to the bolt, and then when the locking member 600 passes through the sixth connecting part 503, the fifth connecting part 402 and the third connecting part 302, the locking member 600 can engage with the locking member 600. The bolt at the bottom of the third connecting part 302 is threaded and abuts against the sixth connecting part 503. As the locking member 600 is gradually screwed into the bolt, the locking member 600 can apply a force away from the body groove 101 to the third connecting part 302 and the fifth connecting part 402, thereby further fixing the second connecting part 301 to the first connecting part 202. At the same time, the locking member 600 can correspondingly apply a force towards the body groove 101 to the sixth connecting part 503, so that the second fixing part 501 is correspondingly subjected to a force abutting against the second surface 120, and / or the third fixing part 502 is correspondingly subjected to a force abutting against the third surface 130, thereby the fourth connecting member 500 can be fixed to the roof beam 102 and / or the cross beam 103.

[0035] It should be noted that, in this embodiment, the locking member 600 is used to connect between the second connector 300, the third connector 400 and the fourth connector 500, so as to apply a force to the second connector 300 and the third connector 400 toward the vehicle body groove 101 and to apply an opposite force to the fourth connector 500, so as to strengthen the connection structure of the vehicle body assembly 10. Understandably, in other embodiments of this application, the locking member 600 may also be other components that can cooperate with the second connector 300, the third connector 400 and the fourth connector 500 to achieve corresponding functions. For example, the locking member 600 may be a component that can engage with the second connector 300 and the third connector 400 and can use the engaging structure to restrict the movement of the second connector 300 toward the vehicle body groove 101. Thus, when the second connector 300 and the third connector 400 engage with the locking member 600 under the action of external force, the vehicle body can also form a stable connection structure with the cooperation of the second connector 300, the third connector 400 and the fourth connector 500 and the locking member 600. This embodiment is only an example and is not specifically limited in the embodiments of this application.

[0036] In addition, the second connector 300 also includes a seventh connector 303, and the third connector 400 also includes an eighth connector 403. The seventh connector 303 is disposed between the second connector 301 and the third connector 302, and the eighth connector 403 is disposed between the fourth connector 401 and the fifth connector 402. The seventh connector 303 can be snapped into the eighth connector 403.

[0037] Furthermore, the first fixing part 201 is fixed to the first surface 110, and the first fixing part 201 and the first connecting part 202 can form a first preset angle α, so that the first connecting part 202 is disposed in the vehicle body groove 101. At the same time, the second connecting part 301 and the seventh connecting part 303 can form a second preset angle β, and the fourth connecting part 401 and the eighth connecting part 403 can form a second preset angle β, so that the first connecting part 202 can be engaged with the second connecting part 301 and the fourth connecting part in the vehicle body groove 101. 401, thereby enabling the second connector 300 and the third connector 400 to be inserted into the body groove 101 through the gap between the roof beam 102 and the body groove 101 and snapped onto the first connector 200 fixed on the first surface 110, thereby enabling the fourth connector 500 to be fixed to the roof beam 102 and / or the crossbeam 103 by means of the second connector 300 and the third connector 400, so that external roof accessories such as roof racks can be fixed to the roof without damage by means of the fourth connector 500.

[0038] It should be noted that in the embodiments of this application, the fixed connection between components can be one or more of the following connection methods: riveting, welding, bonding, bolting, keying, snap-fitting, etc., or it can be integrally formed. For those skilled in the art, they can determine which connection method to adopt based on the specific circumstances.

[0039] Furthermore, please refer to the following: Figures 5 and 6 , Figure 5 yes Figure 2 A schematic diagram of the structure of the first connector 200 in the embodiment. Figure 6 yes Figure 5 A schematic diagram of the first connector 200 from another angle in the embodiment. Optionally, in this embodiment, the first connector 200 has a first fixing part 201 and a first connecting part 202 at both ends.

[0040] The first fixing part 201 has two ends recessed to form a first sub-fixing part 210 and a second sub-fixing part 220, respectively. The first sub-fixing part 210 and the second sub-fixing part 220 are fixed to the first surface 110 to strengthen the overall strength of the first connector 200 and prevent the vehicle body assembly 10 from being damaged due to insufficient strength of the first connector 200.

[0041] Furthermore, a drainage position 230 is formed between the first sub-fixing part 210 and the second sub-fixing part 220 so that water flowing to the first fixing part 201 can flow out through the drainage position 230. The drainage position 230 may be a hole formed between the first sub-fixing part 210 and the second sub-fixing part 220 to prevent water flowing into the vehicle body groove 101 from being blocked by the first fixing part 201.

[0042] Furthermore, the first surface 110 may be provided with a drainage section, such as a water guide channel inclined outward, to drain water on the first surface 110 to the outside. In addition, the second surface 120 and the third surface 130 may also be provided with drainage sections to drain water to the outside or into the vehicle body groove 101. Understandably, the drainage position 230 allows water flowing to the first fixing part 201 to flow out without being obstructed at the first fixing part 201.

[0043] Furthermore, one or more reinforcing portions 260 may be provided between the first fixing portion 201 and the first connecting portion 202. The reinforcing portion 260 may be a reinforcing rib protruding from the surface of the first connector 200 to increase the strength of the first snap-fit ​​portion 240. In this embodiment, three protruding reinforcing ribs are provided between the first fixing portion 201 and the first connecting portion 202 to prevent damage to the vehicle body assembly 10 due to insufficient strength of the first snap-fit ​​portion 240.

[0044] Optionally, the first connecting portion 202 protrudes outward from the first fixing portion 201 to form a first engaging portion 240, which is used to engage the second connecting member 300 and the third connecting member 400 to both ends of the first connecting portion 202. In addition, a first limiting portion 250 is formed at the end of the first engaging portion 240 opposite to the first fixing portion 201, which is used to limit the movement of the second connecting member 300 and the third connecting member 400 relative to the first engaging portion 240 in a third direction. The third direction can be a direction opposite to the first connecting portion 202. In other words, the first limiting portion 250 can further stabilize the engaging structure between the first engaging portion 240 and the second connecting member 300 and the third connecting member 400, and prevent the second connecting member 300 and the third connecting member 400 from moving in a direction opposite to the first connecting portion 202.

[0045] Please also refer to Figures 7 to 8 , Figure 7 yes Figure 2 A schematic diagram of the structure of the second connector 300 in the embodiment. Figure 8 yes Figure 2A schematic diagram of the third connector 400 in the embodiment. The second connector 300 has a second connecting portion 301 and a third connecting portion 302 at both ends, and the third connector 400 has a fourth connecting portion 401 and a fifth connecting portion 402 at both ends. The second connecting portion 301 and the fourth connecting portion 401 are used to engage with the first connector 200 in the vehicle body groove 101, and the third connecting portion 302 and the fifth connecting portion 402 are used to engage with the fourth connector 500 to connect to the side of the roof beam 102 opposite to the vehicle body groove 101.

[0046] The second connecting portion 301 has a recessed end forming a second engaging portion 310 that matches the first engaging portion 240, and the fourth connecting portion 401 has a recessed end forming a third engaging portion 410 that matches the first engaging portion 240 and the second engaging portion 310 respectively. The second engaging portion 310 and the third engaging portion 410 can be engaged with the first engaging portion 240.

[0047] Specifically, the first snap-fit ​​portion 240 can be a boss provided at one end of the first connector 200 for snapping into the second connector 300 and the third connector 400. The second snap-fit ​​portion 310 and the third snap-fit ​​portion 410 can be recesses provided at the ends of the second connector 300 and the third connector 400 respectively, which match the first snap-fit ​​portion 240, for engaging with the first snap-fit ​​portion 240 to achieve a detachable fixed connection between the first connector 200, the second connector 300 and the third connector 400.

[0048] Furthermore, in this embodiment, the seventh connecting portion 303 is also provided with a fourth engaging portion 320, and the eighth connecting portion 403 is also provided with a fifth engaging portion 420. The fourth engaging portion 320 may be formed by one end of the seventh connecting portion 303 protruding outward toward the third connecting member 400, and the fifth engaging portion 420 may be formed by one end of the eighth connecting portion 403 recessed away from the second connecting member 300. The fourth engaging portion 320 and the fifth engaging portion 420 can be matched and engaged to restrict the second engaging portion 310 relative to the first engaging portion 240 along the... The movement in one direction restricts the movement of the fourth latching part 320 relative to the first latching part 240 in a second direction. The first direction may be the direction away from the third connector 400, and the second direction may be the direction away from the second connector 300. In other words, the latching between the fourth latching part 320 and the fifth latching part 420 can stabilize the connection structure between the second connector 300 and the third connector 400, thereby realizing a convenient and stable detachable fixed connection between the first connector 200 and the second connector 300.

[0049] In this embodiment, the fourth engaging portion 320 can be a dovetail-shaped protrusion, and the fifth engaging portion 420 can be a dovetail groove that matches the fourth engaging portion 320. It is understood that in other embodiments of this application, the shape and structure of the fourth engaging portion 320 and the fifth engaging portion 420 are not limited to this embodiment. For example, the fourth engaging portion 320 can be a boss with a protrusion in the middle, and the fifth engaging portion 420 can be a groove that matches the fourth engaging portion 320, or the fifth engaging portion 420 can be a boss and the fourth engaging portion 320 can be a corresponding groove, etc. As long as the fourth engaging portion 320 and the fifth engaging portion 420 can engage and restrict the second connecting member 300 and the third connecting member 400 from moving in opposite directions, no specific limitation is made here.

[0050] Furthermore, the first limiting part 250 can be used to stabilize the snap-fit ​​structure between the first snap-fit ​​part 240, the second snap-fit ​​part 310 and the third snap-fit ​​part 410, so as to restrict the movement of the second snap-fit ​​part 310 and the third snap-fit ​​part 410 away from the first connector 200. It can be understood that the first limiting part 250 is not limited to the shape and structure of this embodiment. For example, the first limiting part 250 can also be a protrusion with one end of the first snap-fit ​​part 240 protruding upward away from the first fixing part 201, etc., as long as it can restrict the movement of the second connector 300 and the third connector 400 away from the first connector 200, and no specific limitation is made here.

[0051] The applicant's research found that existing snap-fit ​​connectors have structural problems such as inconvenient disassembly or unstable connection. Using such snap-fit ​​connectors in the connection between roof accessories and rain gutters easily leads to inconvenient disassembly or unstable installation of the connection structure. Detachable installation is one of the main advantages of snap-fit ​​structures. The detachable installation structure applied to the connection structure between rain gutters and roof accessories facilitates the disassembly of roof accessories and allows the installation structure to be disassembled together after the roof accessories are removed without affecting the aesthetics of the vehicle body; and stable installation is a necessary function to avoid safety hazards in the installation of roof accessories. Therefore, this application provides a detachable and stable vehicle body component 10 to solve the above-mentioned technical problems. In this embodiment, the first connector 200 and the second connector 300 can achieve a stable detachable connection by utilizing the cooperation structure of the first snap-fit ​​part 240 with the second snap-fit ​​part 310, the third snap-fit ​​part 410, the fourth snap-fit ​​part 320, and the fifth snap-fit ​​part 420.

[0052] Please refer to Figures 9 to 11 , Figure 9 yes Figure 2 A schematic diagram of the structure when the first connector 200, the second connector 300, and the third connector 400 are initially engaged in the embodiment. Figure 10 yes Figure 9A schematic diagram of the structure when the first connector 200, the second connector 300, and the third connector 400 are further engaged in the embodiment. Figure 11 yes Figure 10 A schematic diagram of the structure when the first connector 200, the second connector 300 and the third connector 400 are further engaged in the embodiment.

[0053] During the engagement process of the first connector 200 with the second connector 300 and the third connector 400, the second connector 300 and the third connector 400 are first inserted into the vehicle body groove 101 until the positions of the second engagement part 310 and the third engagement part 410 correspond to the positions of the first engagement part 240.

[0054] Furthermore, the second connecting part 301 and the fourth connecting part 401 move towards each other so that the second locking part 310 and the third locking part 410 are inserted into the first locking part 240, thereby completing the engagement of the first locking part 240 with the second locking part 310 and the third locking part 410. Then, the seventh connecting part 303 and the eighth connecting part 403 move towards each other so that the fourth locking part 320 is engaged with the fifth locking part 420.

[0055] Furthermore, the third connecting part 302 and the fifth connecting part 402 are matched and adjusted to make the second connecting member 300 and the third connecting member 400 more securely connected, and to make the connection positions of the third connecting part 302, the fifth connecting part 402 and the fourth connecting member 500 correspond.

[0056] Furthermore, when the first connector 200 forms a fixed connection structure with the second connector 300 and the third connector 400 in the body groove 101, the third connecting part 302 and the fifth connecting part 402 are provided on the side of the roof beam 102 opposite to the body groove 101, for connection with the fourth connector 500. Please refer to the following reference. Figure 12 and Figures 2 to 4 , Figure 12 yes Figure 2 A schematic diagram of the structure of the fourth connector 500 in the embodiment.

A through hole 510 matching the third connecting part 302 can be formed in the middle of the sixth connecting part 503. The third connecting part 302 can pass through the through hole 510 and cooperate with the locking member 600 to fix the second fixing part 501 to the roof beam 102, and / or fix the third fixing part 502 to the cross beam 103. At the same time, it further strengthens the connection structure between the first connector 200 and the second connector 300. The specific process has been described above and will not be repeated here.

Thus, the locking member 600 can cooperate with the third connecting part 302 and the fifth connecting part 402 to achieve a stable connection of the vehicle body assembly 10. In addition, in other embodiments of this application, the locking member 600 may not be provided, and the sixth connecting part 503 may be omitted. The device may be equipped with screws that match the third connecting part 302 and the fifth connecting part 402. The sixth connecting part 503 can cooperate with the third connecting part 302 and the fifth connecting part 402 to connect the second connecting part 300, the third connecting part 400 and the fourth connecting part 500, so that the fourth connecting part 500 is fixed to the roof of the vehicle. At the same time, it further strengthens the snap-fit ​​between the first connecting part 200 and the second connecting part 300 and the third connecting part 400. Other structures that can achieve the corresponding functions may also be adopted in the embodiments of this application, which are not specifically limited here.
