Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a retractor mounting structure and vehicle. Background Technology

[0002] With the improvement of living standards, the automotive industry has developed rapidly. At the same time, consumers have increasingly higher requirements for vehicle safety. Seat belts are an important component for ensuring the safety of vehicle occupants. Seat belts typically include components such as a retractor, belt body, and buckle. Among them, the retractor is fixed to the vehicle frame and is responsible for retracting and extending the belt body.

[0003] In related technologies, the retractor is mounted on a sheet-like mounting plate, which has relatively weak structural strength. For example, in a rear-end collision, the occupant leans forward due to inertia, and the seatbelt's strap tightens around the occupant to restrict this forward lean. However, because the retractor's mounting structure is weak, the tensile force transmitted from the strap to the retractor can easily cause the mounting plate to bend, tear, or otherwise fail, leading to seatbelt failure and thus rendering it ineffective in restricting occupant movement and ensuring occupant safety.

[0044] With the improvement of living standards, the automotive industry has developed rapidly. At the same time, consumers have increasingly higher requirements for vehicle safety. Seat belts are an important component for ensuring the safety of vehicle occupants. Seat belts typically include components such as a retractor, belt body, and buckle. Among them, the retractor is fixed to the vehicle frame and is responsible for retracting and extending the belt body.

[0045] In related technologies, the retractor is mounted on a sheet-like mounting plate, which has relatively weak structural strength. For example, in a rear-end collision, the occupant leans forward due to inertia, and the seatbelt's strap tightens around the occupant to restrict this forward lean. However, because the retractor's mounting structure is weak, the tensile force transmitted from the strap to the retractor can easily cause the mounting plate to bend, tear, or otherwise fail, leading to seatbelt failure and thus rendering it ineffective in restricting occupant movement and ensuring occupant safety.

[0046] To address the aforementioned problems, the first aspect of this application proposes a retractor mounting structure. This structure, used for mounting a retractor, provides a higher-strength mounting platform for the retractor, thereby reducing the probability of seatbelt failure. Specifically, as shown... Figures 1 to 2 As shown, the mounting structure includes a first box structure 700 and a second box structure 800. The first box structure 700 is used to mount the retractor. The first box structure 700 is connected to the second box structure 800. The first box structure 700 defines a first buffer cavity, and the second box structure 800 defines a second buffer cavity. Thus, when the retractor is subjected to impact, it can be damped and buffered through the first buffer cavity and the second buffer cavity to reduce the probability of structural failure.

[0047] Specifically, the first box-shaped structure 700 includes a third mounting component 100 and a fourth mounting component 200. The third mounting component 100 is used to mount a retractor. The third mounting component 100 is horizontally positioned and has holes such as a retractor mounting hole, a retractor anti-rotation hole 110, a wire harness mounting hole, and positioning holes. The retractor anti-rotation hole 110 has a non-axisymmetric shape and can be a triangular hole, a square hole, or something else. Figure 3 and Figure 4 The irregular holes shown are to prevent the retractor from rotating.

[0048] The third mounting member 100 is used on one side along the width direction of the vehicle body to connect with the inner body panel 900, as follows: Figure 1 Taking the rear seatbelt retractor mounting structure as an example, the vehicle body inner panel 900 includes a C-pillar inner panel 910 and a rear wheel arch inner panel 920. In other embodiments, for the front seatbelt retractor mounting structure, the vehicle body inner panel 900 may be a B-pillar inner panel. The third mounting member 100 is connected to the fourth mounting member 200 on the other side along the width direction of the vehicle body, such as... Figure 1 As shown, the fourth mounting member 200 extends along the height of the vehicle body and is inclined. Its upper end is connected to the third mounting member 100, and its lower end gradually approaches the inner body panel 900 and is connected and fixed to the inner body panel 900. Thus, the third mounting member 100, the fourth mounting member 200, and the inner body panel 900 together enclose and define the first buffer cavity (see reference). Figure 1 and Figure 2 As shown in the diagram, it can be understood that when viewed along the length of the vehicle body, the first box-shaped structure 700 presents a triangular shape. The third mounting piece 100, the fourth mounting piece 200, and the inner body panel 900 form a triangular support structure, which can provide more stable support for the retractor. In the event of a frontal or side collision, the triangular support structure can effectively disperse the impact force, reduce the risk of deformation of the third mounting piece 100, and ensure that the seat belt works normally.

[0049] It should be noted that, as Figure 1 and Figure 2 As shown, the length direction of the vehicle body is the X direction, the width direction is the Y direction, and the height direction is the Z direction.

[0050] In addition, to enhance the protective effect during a frontal collision and improve the strength of the mounting structure along the length of the vehicle body, such as Figure 1 and Figure 2As shown, a second box-shaped structure 800 is also provided at the front end of the first box-shaped structure 700. The second box-shaped structure includes a first mounting member 300 and a second mounting member 400. The second buffer cavity is defined by the first mounting member 300, the second mounting member 400, and the vehicle body inner panel 900. Both the first mounting member 300 and the second mounting member 400 are located at the front end of the third mounting member 100, and at least one of the first mounting member 300 and the second mounting member 400 is directly connected to the third mounting member 100. One side of the first mounting member 300 along the width direction of the vehicle body is used to connect to the vehicle body inner panel 900, and the other side is connected to the second mounting member 400. The first mounting member 300 extends along the length direction of the vehicle body, and the second mounting member 400 extends along the height direction of the vehicle body. The lower end of the second mounting member 400 is connected to the vehicle body inner panel 900, thereby the first mounting member 300, the second mounting member 400, and the vehicle body inner panel 900 enclose and define the second buffer cavity. The second box-shaped structure 800 and the first box-shaped structure 700 may or may not be connected. The presence of the second box structure 800 further enhances the overall structure's impact resistance. When the vehicle collides at high speed, the second box structure 800 can absorb and disperse the impact energy to ensure the seat belt functions properly.

[0051] Based on the above, the retractor mounting structure in this embodiment forms a two-section box-like structure through multiple mounting components. This enhances the retractor's side impact protection and frontal impact protection performance, thereby improving the overall safety performance of the vehicle and ensuring effective protection for passengers in various collision accidents, reducing the risk of personal injury caused by seatbelt failure. Furthermore, this structure is simple in design, easy to produce and install, reduces manufacturing costs, and simultaneously improves the vehicle's reliability and durability, providing a guarantee for driving safety.

[0052] In some embodiments, such as Figures 3 to 5As shown, the fourth mounting component 200 includes a first main body 210, a first flange 220, and a second flange 230. The first main body 210 extends along the height direction of the vehicle body, and both the first flange 220 and the second flange 230 extend towards the inner body panel 900 along the width direction of the vehicle body. The first flange 220 and the second flange 230 are respectively formed by sheet metal at both ends of the first main body 210 along the length direction of the vehicle body. The top end of the first main body 210 is connected to the third mounting component 100, and the bottom end of the first main body 210 is used to connect to the inner body panel 900. The first flange 220 and the second flange 230 are arranged side by side. The first flange 220 is connected to the third mounting member 100 and the second mounting member 400 respectively, and the second flange 230 is connected to the third mounting member 100. The first flange 220 and the second flange 230 are located at the front end and the rear end of the first box-shaped structure 700 respectively, thus forming the front wall and the rear wall of the first box-shaped structure 700, which can play a reinforcing role for the first box-shaped structure 700. When the vehicle is subjected to a side collision, the first flange 220 and the second flange 230 can effectively resist the impact force, prevent the first box-shaped structure 700 from deforming, ensure the stable operation of the retractor, and further protect passenger safety.

[0053] Specifically, such as Figure 5 As shown, the main body of the first flange 220 extends toward the inner body panel 900 (reference). Figure 1 and Figure 2 The third mounting component 100 is provided with a first flange 221 and a second flange 222. The first flange 221 is bent relative to the main body of the first flange 220 and fits against the outer wall of the third main body 410 of the second mounting component 400, thereby facilitating welding or bolt connection. The second flange 222 is bent relative to the main body of the first flange 220 and fits against the lower wall of the third mounting component 100, thereby facilitating welding or bolt connection. The third mounting component 100 and the second mounting component 400 are connected by the first flange 220, thereby realizing multi-point and multi-object connection and enhancing the stability and integrity of the structure. Figure 6 As shown, the upper part of the second flange 230 is connected to the third mounting member 100 through the sixth mounting member 600, and the lower part of the second flange 230 is connected to the fifth mounting member 500. The fixing to the inner body panel 900 is achieved through the transition of the fifth mounting member 500.

[0054] Furthermore, such as Figure 3 As shown, the first main body 210 is tilted toward the inner body panel 900 in a direction away from the third mounting member 100, so that the distance between the first main body 210 and the inner body panel 900 gradually decreases, thereby optimizing the space utilization of the structure, reducing the occupancy of the vehicle's interior space, and improving passenger comfort. At the same time, the tilted design helps to disperse the impact force during a collision and enhances structural stability.

[0055] Furthermore, such as Figures 3 to 5 As shown, the retractor mounting structure also includes a fifth mounting member 500, which is disposed at the lower end of the fourth mounting member 200. The fifth mounting member 500 includes a second main body 510 and a third flange 520. The second main body 510 is used to connect the first main body 210 and the inner body panel 900, and the third flange 520 is connected to the second flange 230.

[0056] It should be noted that, in the embodiments of this application, the vehicle body inner panel 900 includes an upper C-pillar inner panel 910 and a lower rear wheel arch inner panel 920, which are welded together to form an integral structure. The inner side of the rear wheel arch inner panel 920 forms the vehicle interior space, while the outer side forms the wheel hub. Therefore, the second main body 510 of this application is connected to the vehicle body inner panel 900 by welding, thereby avoiding the need for opening holes in the rear wheel arch inner panel 920, reducing potential risks such as water and dust seepage, and enhancing the overall rigidity and safety of the vehicle body.

[0057] In some embodiments, such as Figure 1 , Figure 3 and Figure 5 As shown, the third mounting component 100 is welded and fixed to the inner body panel 900, the first mounting component 300, and the sixth mounting component 600, respectively. The first mounting component 300 is welded and fixed to the third mounting component 100, the inner body panel 900, and the second mounting component 400, respectively. The second mounting component 400 is welded and fixed to the first mounting component 300 and the inner body panel 900, respectively. The fifth mounting component 500 is welded and fixed to the inner body panel 900. The fourth mounting component 200 is bolted and fixed to the third mounting component 100, the second mounting component 400, the fifth mounting component 500, and the sixth mounting component 600, respectively. It should be noted that this application uses spot welding to complete the welding and fixing of each mounting component. During the welding process, welding electrodes need to be arranged on the inner and outer sides of the plates to be welded. In order to provide an entrance and exit for the welding electrodes to enter or exit the box-shaped structure, the fourth mounting component 200 needs to be installed after the other mounting components are welded and fixed. When assembling the fourth mounting component 200, the welding electrode cannot extend into the interior of the box-shaped structure. Therefore, the fourth mounting component 200 adopts a screw connection process, which has good structural strength and simple assembly requirements.

[0058] In addition, if there are welding errors in the welding process of the other mounting parts, the screw connection of the fourth mounting part 200 can be used to compensate for them, so as to reduce the situation where the mounting parts cannot be matched and thus scrapped.

[0059] In some embodiments, such as Figure 3 and Figure 4As shown, the second mounting component 400 includes a third main body 410, a fourth flange 420, and a fifth flange 430. The third main body 410 extends along the height direction of the vehicle body, and the fourth flange 420 and the fifth flange 430 both extend towards the inner body panel 900 along the width direction of the vehicle body. The fourth flange 420 and the fifth flange 430 are respectively formed by sheet metal at both ends of the third main body 410 along the length direction of the vehicle body. The third main body 410 is connected to the first mounting component 300, as shown... Figure 4 As shown, the first mounting component 300 has a seventh flange 310 on one side along the width direction of the vehicle body. The seventh flange 310 is fitted to the third main body 410 and can be welded together to form an integral structure. (Reference) Figure 1 As shown, the bottom end of the third main body 410 is used to connect with the inner body panel 900. The fourth flange 420 and the fifth flange 430 are arranged side by side. The fourth flange 420 is connected to the inner body panel 900 and the first mounting member 300 respectively, and the fifth flange 430 is connected to the third mounting member 100.

[0060] Specifically, such as Figure 3 As shown, the fourth flange 420 is provided with a third flange 421 located at the top of the main body of the fourth flange 420. The third flange 421 is attached to the first mounting member 300, thereby facilitating welding to form an integral structure. The fourth flange 420 is also provided with a fourth flange 422 located on the side of the fourth flange 420 away from the third main body 410. The fourth flange 422 is welded to the corresponding part of the inner body panel 900 to ensure the tightness and stability of the structure.

[0061] Furthermore, such as Figure 3 and Figure 7 As shown, the rear end of the first mounting member 300 is stacked on the top surface of the third mounting member 100 and connected to the third mounting member 100. The fifth flange 430 extends to the lower side of the third mounting member 100. The connection position of the fifth flange 430 and the third mounting member 100 avoids the connection position of the first mounting member 300 and the second mounting member 400, so as to ensure the effective distribution of welding points and avoid the welding weakness caused by the overlap of welding points.

[0062] like Figure 4 and Figure 7 As shown, the fifth flange 430 is provided with an intersecting fifth flange 431 and a sixth flange 432. The fifth flange 431 is located at the bottom of the third mounting member 100 and is used for welding to the third mounting member 100. The sixth flange 432 is located inside the flange of the third mounting member 100, and the connection between the sixth flange 432, the flange of the third mounting member 100, and the inner body panel 900 is achieved through three layers of welding.

[0063] In some embodiments, such as Figure 4 and Figure 7As shown, the retractor mounting structure also includes a sixth mounting member 600, which includes a fourth main body portion 610 and a sixth flange 620. The fourth main body portion 610 is fitted to the third mounting member 100, thereby increasing the thickness of the third mounting member 100 and improving its impact resistance. The sixth flange 620 extends downward along the vehicle body height direction and overlaps with and connects to the second flange 230 of the fourth mounting member 200.

[0064] Furthermore, the retractor mounting structure also includes a reinforcing member 150, such as... Figure 4 and Figure 7 As shown, corresponding to the retractor's mounting position, the reinforcing member 150 is connected to the fourth main body 610 of the sixth mounting member 600, thus creating a three-layer thickened structure at the retractor's mounting position: the third mounting member 100, the sixth mounting member 600, and the reinforcing member 150, further enhancing impact resistance. The third mounting member 100, the sixth mounting member 600, and the reinforcing member 150 are fixed by three-layer welding. The sixth mounting member 600 and the reinforcing member 150 are provided with holes communicating with the anti-rotation hole 110 of the third mounting member 100 to facilitate the installation of the retractor.

[0065] In some embodiments, such as Figure 2 As shown, the dimension of the first mounting member 300 along the width of the vehicle body is smaller than that of the third mounting member 100 along the width of the vehicle body. The first mounting member 300 is elongated, forming a box-like structure while occupying as little interior space as possible, ensuring maximum utilization of the interior space. Thus, the entire retractor mounting structure has an inverted L-shape, with the second box-like structure 800 at the front end being narrower and the first box-like structure 700 at the rear end being wider.

[0066] In some embodiments, the retractor mounting structure of this application can not only be used to fix the retractor, but also to provide a mounting base for other components. For example, the third mounting member 100 can also be used to fix the wire harness, the fourth mounting member 200 can also be used to install the interior panel, the second mounting member 400 can also be used to install the seat bracket, and so on.

[0067] The second aspect of this application provides a vehicle including an inner body panel 900 and a retractor mounting structure as described in any of the above embodiments, the retractor mounting structure being connected to the inner body panel 900. The vehicle can be a private car, such as a sedan, SUV, MPV, or pickup truck. It can also be a commercial vehicle, such as a van, bus, small truck, or large trailer. The vehicle can be a gasoline-powered vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle. Since the vehicle of this aspect includes the retractor mounting structure of the above embodiments, it has the beneficial effects described in the above embodiments, which will not be repeated here.

[0068] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
