Description

Technical Field

[0001] This utility model relates to the field of vehicle parts, specifically to a roof hook assembly, a roof, and a vehicle. Background Technology

[0002] With the development of automotive technology, people have placed increasingly higher demands on the functionality of the vehicle's interior space, such as installing coat hooks on the roof to facilitate the placement of clothing, bags, and other items by passengers. In related technologies, the roof lining is located below the roof sheet metal. When installing coat hooks, the upper end of the hook is typically passed through the hook mounting hole on the roof lining and fixed to a mounting bracket on the roof sheet metal with bolts. This installation method is highly susceptible to dimensional deviations between the roof sheet metal and the roof lining, which can cause misalignment between the center line of the threaded hole on the coat hook and the center line of the threaded hole on the mounting bracket. This can result in the coat hook failing to be installed on the mounting bracket or leaving significant assembly gaps. Utility Model Content

[0003] This utility model aims to solve the technical problem in related technologies that ceiling hook components are difficult to install and are prone to assembly gaps.

[0004] In a first aspect, this utility model provides a roof hook assembly, including a hook body, a bracket, and a buckle. The bracket is used to install on the roof sheet metal and has a locking hole. The buckle includes a locking post and a limiting head at one end of the locking post. The end of the locking post away from the limiting head is connected to the hook body. The size of the locking post is smaller than the size of the locking hole. The locking post is used to pass through the hook mounting hole on the roof and the locking hole and has an movable gap with the locking hole. The limiting head is used to abut against the end face of the bracket away from the roof.

[0005] Optionally, the buckle and the hook body are an integral structure; and / or, the bracket and the roof sheet metal are an integral structure.

[0006] Optionally, the limiting head is provided with a guide slope.

[0007] Optionally, the hook body is provided with a limiting protrusion around the buckle. The height of the limiting protrusion is less than the length of the buckle post. The limiting protrusion is used to abut against the end face of the bracket near the ceiling when the buckle post passes through the buckle hole.

[0008] Optionally, the roof hook assembly further includes a flexible connector, one end of which is connected to the hook body, and the other end of which is used to connect to the roof sheet metal. The flexible connector is used to suspend the hook body on the roof sheet metal when the buckle disengages from the buckle hole.

[0009] Optionally, the hook body is provided with a positioning post around the buckle, and the bracket is provided with a positioning hole for insertion and engagement with the positioning post.

[0010] Optionally, a portion of the positioning post extends out of the positioning hole, and one end of the flexible connector is connected to the portion of the positioning post that extends out of the positioning hole.

[0011] Optionally, the buckle is a plastic buckle.

[0012] Secondly, this utility model proposes a vehicle roof, including a roof sheet, a canopy, and the aforementioned canopy hook assembly. The canopy is located on the side of the roof sheet facing the interior of the vehicle. The bracket of the canopy hook assembly is connected to the roof sheet. The canopy is provided with hook mounting holes, and the hook body of the canopy hook assembly is placed in the hook mounting holes.

[0013] Thirdly, this utility model also proposes a vehicle, including the aforementioned roof.

[0014] The roof hook assembly, roof, and vehicle of this utility model have at least the following advantages compared to related technologies:

[0015] The roof panel is located on the side of the roof sheet facing the interior of the vehicle. The hook mounting holes on the roof match the shape of the hook body. The bracket can be positioned between the roof panel and the roof sheet. The hook body is connected to the end of the buckle away from the limiting head. The limiting head can be compressed and deformed to pass through the buckle hole of the bracket. Under normal circumstances, when the hook body is installed in the hook mounting hole of the roof, the buckle's buckle and the central axis of the bracket's buckle hole are roughly aligned. At this time, the buckle can smoothly pass through the bracket's buckle hole and the hook body can be installed in place. Furthermore, there will be no assembly gaps between the hook body and the hook mounting hole. If the roof sheet and roof have dimensional deviations that cause the hook mounting hole and the bracket to misalign, the hook body will be installed in place. The bracket's locking holes are misaligned. If the hook body is installed in the hook mounting hole of the roof, the locking post of the buckle and the central axis of the locking hole of the bracket will be offset. However, since the size of the locking post is smaller than the size of the locking hole, there is a gap between the locking post and the locking hole when they are inserted and matched. Therefore, even if there is a misalignment of the central axis, the locking post can still pass through the locking hole, that is, the buckle can still pass through the locking hole on the bracket, and the limiting head can abut against the end face of the bracket away from the roof, so that the hook body can be installed in place. Therefore, the present invention can avoid the difficulty of installing the roof hook assembly and the problem of assembly gaps caused by the size deviation between the roof sheet metal and the roof.

[0027] like Figures 1-5 As shown, an embodiment of the present invention provides a roof hook assembly, including a hook body 1, a bracket 2, and a buckle 3. The bracket 2 is used to install on the roof sheet metal 5, and the bracket 2 is provided with a locking hole 21. The buckle 3 includes a locking post 31 and a limiting head 32 provided at one end of the locking post 31. The end of the locking post 31 away from the limiting head 32 is connected to the hook body 1. The size of the locking post 31 is smaller than the size of the locking hole 21. The locking post 31 is used to pass through the hook mounting hole 61 on the roof 6 and the locking hole 21, and there is an movable gap between the locking post 31 and the locking hole 21. The limiting head 32 is used to abut against the end face of the bracket 2 away from the roof 6.

[0028] The roof hook assembly of this embodiment can be installed on the roof of any vehicle. The hook body 1 can be a common roof hook, including a fixed base and a hook that are rotatably connected to each other. The hook is used to rotate downward relative to the fixed base to change from a horizontal state to a vertical state, making it convenient for passengers to hang items.

[0029] Specifically, the roof 6 is located below the roof sheet 5, and the bracket 2 can be located between the roof 6 and the roof sheet 5. The bracket 2 can be installed on the roof sheet 5 by means of bolts or other fixing methods. The bracket 2 is provided with a locking hole 21 that runs through the vertical direction of the vehicle. The shape of the locking hole 21 is not limited. The locking post 31 of the buckle 3 has a cross-sectional dimension perpendicular to its extension direction that is smaller than the size of the locking hole 21. The limiting head 32 is located at one end of the locking post 31 and its cross-sectional dimension is larger than the size of the locking hole 21. The limiting head 32 and / or the bracket 2 can deform so that the limiting head 32 can pass through the locking hole 21 with the locking post 31 and abut against the end face of the bracket 2, preventing the buckle 3 from detaching from the locking hole 21.

[0030] The hook mounting hole 61 on the ceiling 6 is usually matched with the shape of the hook body 1, so that after the hook body 1 is fixed to the bracket 2 by the buckle 3, the hook body 1 is embedded in the hook mounting hole 61 and is installed in conjunction with the hook mounting hole 61.

[0031] like Figure 4 As shown, the buckle 3 in this embodiment may include two symmetrical snap-fit ​​arms. The arm portions 331 of the two snap-fit ​​arms form a snap-fit ​​post 31, and the hook portions 332 of the two snap-fit ​​arms form a limiting head 32. Of course, the form of the buckle 3 in this embodiment is not limited to this. For example, it may also be a structure in which one arm portion 331 is symmetrically connected to two hook portions 332.

[0032] In this embodiment, the hook body 1 is connected to the end of the buckle 3's locking post 31 away from the limiting head 32. The limiting head 32 can undergo extrusion deformation and pass through the locking hole 21 of the bracket 2. Under normal circumstances, when the hook body 1 is matched and installed in the hook mounting hole 61 of the roof 6, the locking post 31 of the buckle 3 is roughly aligned with the central axis of the locking hole 21 of the bracket 2. At this time, the buckle 3 can smoothly pass through the locking hole 21 of the bracket 2 and realize the installation of the hook body 1. Furthermore, there will be no assembly gap between the hook body 1 and the hook mounting hole 61. If the roof sheet metal 5 and the roof 6 are misaligned with the locking hole 21 of the bracket 2 due to dimensional deviations, then if the hook body 1 is matched and installed in the roof 6, the hook mounting hole 61 and the locking hole 21 of the bracket 2 will be misaligned. In the hook mounting hole 61 of the roof 6, the locking post 31 of the buckle 3 and the locking hole 21 of the bracket 2 will be offset and misaligned. However, since the size of the locking post 31 is smaller than the size of the locking hole 21, there is a gap between the locking post 31 and the locking hole 21 when they are inserted and matched. Therefore, even if there is a misalignment of the central axis, the locking post 31 can still pass through the locking hole 21, that is, the buckle 3 can still pass through the locking hole 21 on the bracket 2, and the limiting head 32 abuts against the end face of the bracket 2 away from the roof 6, that is, the upper end face of the bracket 2, so as to realize the installation of the hook body 1. Therefore, this embodiment can avoid the difficulty of installing the roof hook assembly and the problem of assembly gaps caused by the size deviation of the roof sheet metal 5 and the roof 6.

[0033] Optionally, the buckle 3 and the hook body 1 are an integral structure; and / or, the bracket 2 and the roof sheet metal 5 are an integral structure.

[0034] In this embodiment, the buckle 3 and the hook body 1 are an integral structure, which can reduce the number of parts of the ceiling hook assembly and improve the connection stability between the buckle 3 and the hook body 1.

[0035] The bracket 2 can be made of metal. The bracket 2 and the roof sheet 5 are designed as an integrated structure, which can simplify the molding process and effectively improve the connection stability between the bracket 2 and the roof sheet 5.

[0036] like Figure 4 As shown, optionally, the limiting head 32 is provided with a guide slope 321, so that the limiting head 32 forms a tapered structure with the cross-sectional size gradually decreasing from the end close to the hook body 1 toward the direction away from the hook body 1. The buckle 3 can smoothly pass through the hook mounting hole 61 and the buckle hole 21 under the guidance of the limiting head 32 and abut against the end face of the bracket 2.

[0037] like Figure 4 As shown, optionally, the hook body 1 is provided with a limiting protrusion 11 around the buckle 3. The setting height of the limiting protrusion 11 is less than the length of the locking post 31. The limiting protrusion 11 is used to abut against the end face of the bracket 2 near the canopy 6 when the locking post 31 passes through the locking hole 21.

[0038] Specifically, taking the state of the hook body 1 installed on the top of the vehicle as an example, the top of the hook body 1 is provided with a buckle 3 and a limiting boss 11. The limiting boss 11 can be integrally formed with the hook body 1 to simplify the forming process. One or more limiting bosses 11 can be provided.

[0039] In this embodiment, the height of the limiting boss 11 is less than the length of the locking post 31. By controlling the height of the limiting boss 11, when the locking post 31 passes through the locking hole 21 and the limiting head 32 abuts against the end face of the bracket 2 away from the hook body 1 (i.e., the upper end face), the limiting boss 11 abuts against the end face of the bracket 2 near the hook body 1 (i.e., the lower end face). By using the limiting head 32 and the limiting boss 11 to abut against the upper and lower end faces of the bracket 2 respectively, the buckle 3 is prevented from disengaging from the locking hole 21, ensuring that the hook body 1 can be stably installed on the roof sheet metal 5.

[0040] like Figures 2-5 As shown, optionally, the roof hook assembly also includes a flexible connector 4, one end of which is connected to the hook body 1, and the other end of which is used to connect to the roof sheet metal 5. The flexible connector 4 is used to suspend the hook body 1 on the roof sheet metal 5 when the buckle 3 is disengaged from the buckle hole 21.

[0041] Here, the flexible connector 4 can undergo bending deformation and can be a metal chain, spring, soft rope, etc.

[0042] When the vehicle is in normal use, that is, when the airbag between the roof panel 5 and the roof 6 has not deployed, the hook body 1 is engaged with the fixed bracket 2 of the roof panel 5 by the buckle 3, and the flexible connector 4 is in a bent and contracted state. In the event of an accident, that is, when the airbag between the roof panel 5 and the roof 6 deploys, the airbag pushes the roof 6 downward, causing the buckle 3 to disengage from the buckle hole 21 of the bracket 2. At this time, the hook body 1 is suspended on the roof panel 5 by the flexible connector 4. Since the roof 6 is located between the hook body 1 and the roof panel 5, the hook body 1 can hold the roof 6. By controlling the setting length of the flexible connector 4, the distance that the roof 6 can move downward can be controlled. Under the premise of ensuring that the airbag between the roof panel 5 and the roof 6 has sufficient deployment space, the roof 6 will not fall, so as to avoid injuring the occupants of the vehicle or damaging related structures inside the vehicle.

[0043] like Figures 3-5 As shown, optionally, the hook body 1 is provided with a positioning post 12 around the buckle 3, and the bracket 2 is provided with a positioning hole 22 for inserting and engaging with the positioning post 12.

[0044] Specifically, a positioning post 12 is provided on the top of the hook body 1. The positioning post 12 extends in the vertical direction and can be integrally formed with the hook body 1 to simplify the structure.

[0045] The bracket 2 is provided with a positioning hole 22 that matches the positioning post 12. When installing the hook body 1, the positioning post 12 is inserted into the positioning hole 22. At this time, the locking post 31 of the buckle 3 passes through the locking hole 21 to realize the positioning and assembly of the hook body 1.

[0046] like Figure 3 and Figure 5 As shown, optionally, a portion of the positioning post 12 extends out of the positioning hole 22, and one end of the flexible connector 4 is connected to the portion of the positioning post 12 that extends out of the positioning hole 22.

[0047] Here, the positioning post 12 can be set to be relatively long, so that after the hook body 1 is installed, the positioning post 12 on it will extend upwards out of the positioning hole 22 of the bracket 2. By connecting one end of the flexible connector 4 to the part of the positioning post 12 that extends out of the positioning hole 22, and the other end to the roof sheet metal 5, it can be ensured that the flexible connector 4 can be easily accommodated between the roof 6 and the roof sheet metal 5 when bending, thus avoiding interference between the flexible connector 4 and the surrounding structure.

[0048] Optionally, the buckle 3 is a plastic buckle; on the one hand, the buckle 3 can undergo compression deformation, making it convenient to install the buckle 3 in the buckle hole 21 of the bracket 2; on the other hand, the clamping force is relatively small, making it convenient to disengage from the buckle hole 21 under the action of external force.

[0049] When a vehicle accident occurs, the airbag between the roof panel 5 and the roof 6 deploys, pushing the roof 6 downwards. The locking force between the plastic buckle and the locking hole 21 is much less than the pushing force when the airbag deploys. The plastic buckle disengages from the locking hole 21, ensuring that the airbag has enough space to deploy and can function better.

[0050] like Figure 1 As shown, another embodiment of the present invention provides a car roof, including a car roof sheet 5, a roof canopy 6 and the aforementioned roof canopy hook assembly. The roof canopy 6 is located on the side of the car roof sheet 5 facing the inside of the vehicle. The bracket 2 of the roof canopy hook assembly is connected to the car roof sheet 5. The roof canopy 6 is provided with a hook mounting hole 61, and the hook body 1 of the roof canopy hook assembly is placed in the hook mounting hole.

[0051] Another embodiment of this utility model provides a vehicle including the aforementioned roof. The advantages of this vehicle compared to related technologies are the same as those of the aforementioned roof, and will not be repeated here.

[0052] 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.
