Because the seat belt will pull the retractor when it is stretched, the retractor may be pulled off or the connection may break on the side away from the tension. Therefore, a design with better stability is needed to reduce the risk of the retractor being pulled off. Utility Model Content

[0004] This application provides a vehicle body including a wheel arch; a retractable device having a telescopic end for winding, storing, and extending a seatbelt; and a mounting bracket including a reinforcing plate, a mounting plate, a first support plate, and a second support plate. The reinforcing plate includes a first plate body and a second plate body arranged at an angle. The first plate body connects the second plate body and the wheel arch. The mounting plate connects the second plate body and the retractable device. The mounting plate is spaced apart from the first plate body in a first direction. The first support plate connects the first plate body and the mounting plate. On the side of the mounting bracket opposite to the telescopic end, the second support plate connects the first support plate and the mounting plate.

[0005] In one exemplary embodiment of this application, the mounting bracket includes a third support plate, and the third support plate and the first support plate are spaced apart in a second direction intersecting the first direction.

[0006] In one exemplary embodiment of this application, the third support plate includes a first flange and a second flange spaced apart in the first direction, the first flange being connected to the mounting plate and the second flange being connected to the first plate body.

[0007] In one exemplary embodiment of this application, the first support plate includes a third flange, a fourth flange, and a fifth flange. The third flange and the fourth flange are spaced apart in the first direction. The third flange is connected to the mounting plate, the fourth flange is connected to the first plate body, and the fifth flange is connected to the third flange, the fourth flange, and the second plate body.

[0008] In one exemplary embodiment of this application, the mounting plate includes a sixth flange extending toward the first support plate along the first direction. The sixth flange is connected to the second support plate. The sixth flange and the second support plate are stacked in a second direction perpendicular to the first direction. The second support plate includes a first connecting plate and a second connecting plate arranged at an angle. The first connecting plate is connected to the sixth flange, and the second connecting plate is connected to the second support plate.

[0009] In one exemplary embodiment of this application, the second support plate includes a third connecting plate, which simultaneously connects the first connecting plate, the second connecting plate, and the second plate body.

[0010] In one exemplary embodiment of this application, the winding device forms a limiting groove, the mounting plate forms a limiting protrusion, and the limiting protrusion is located in the limiting groove.

[0012] In one exemplary embodiment of this application, the winding device is disposed on the side of the mounting plate opposite to the first support plate in the first direction.

[0013] This application also provides a vehicle including the aforementioned body.

[0014] The vehicle body and vehicle proposed in this application have the following advantages: the retractable device has a telescopic end for winding and storing seat belts and for extending them; the mounting bracket includes a reinforcing plate, a mounting plate, a first support plate, and a second support plate. The reinforcing plate includes a first plate body and a second plate body arranged at an angle. The first plate body connects to the second plate body and the wheel cover.

When a pulling force is applied to the seat belt, it can be extended and lengthened. During the extension and lengthening process, the pulling force is also applied to the stretching end. While ensuring the ease of installation of the rewinding device, a second support plate connects the first support plate and the mounting plate on the side of the mounting bracket away from the stretching end. This enhances the structural strength of the connection between the first support plate and the mounting plate, reduces the risk of breakage at the connection point, and thus reduces the risk of the rewinding device being pulled off or the connection breaking.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] The seat belt system includes a retractor and a seat belt. The retractor is used to wind up and store the seat belt and to extend it. Because the seat belt will pull the retractor when it is stretched, the retractor may be pulled off on the side away from the tension or the mounting point may break. Therefore, a design with better stability is needed to reduce the risk of the retractor being pulled off.

[0031] To solve the above-mentioned technical problems, this application provides a vehicle body, with reference to... Figure 1 The vehicle body includes a wheel cover 100, a winding device 200, and a mounting bracket 300. The mounting bracket 300 is used to connect the wheel cover 100 and the winding device 200 to increase the ease of installation of the winding device 200 while increasing structural strength.

[0032] In some implementations, combined Figure 2The retractable device 200 has a telescopic end 210 for winding, storing, and extending the seat belt; the mounting bracket 300 includes a reinforcing plate 310, a mounting plate 320, a first support plate 330, and a second support plate 340. The reinforcing plate 310 includes a first plate body 311 and a second plate body 312 arranged at an angle. The first plate body 311 connects the second plate body 312 and the wheel cover 100. The mounting plate 320 connects the second plate body 312 and the retractable device 200. The mounting plate 320 is spaced apart from the first plate body 311 in the first direction Y. The first support plate 330 connects the first plate body 311 and the mounting plate 320. On the side of the mounting bracket 300 opposite to the telescopic end 210, the second support plate 340 connects the first support plate 330 and the mounting plate 320. The reinforcing plate 310 connects the mounting plate 320 and the wheel cover 100 respectively via a first plate body 311 and a second plate body 312 arranged at an angle. The mounting plate 320 and the first plate body 311 are spaced apart in the first direction Y to increase the ease of installation of the winding device 200. When a tension force is applied to pull the seat belt, it can be extended. During the extension process, the tension force also acts on the stretching end. While satisfying the ease of installation of the winding device 200, on the side of the mounting bracket 300 away from the telescopic end 210, the first support plate 330 and the mounting plate 320 are connected by a second support plate 340. This can enhance the structural strength of the connection between the first support plate 330 and the mounting plate 320, reduce the risk of breakage at the connection point, and thus reduce the risk of the winding device 200 being pulled off or the connection breaking.

[0033] In some implementations, refer to Figure 1 The wheel cover 100 is an arc-shaped semi-enclosed structure used to house the tire, wheel hub, and other structures. The wheel cover 100 protects the chassis and reduces the erosion of the chassis by mud and moisture. Specifically, the wheel cover 100 includes structures made of plastic, aluminum, and steel plates. The wheel cover 100 has a mounting surface above the mounting bracket 300 in the first direction Y, and a winding device 200 is connected to the mounting bracket 300. The winding device 200 is located on the side of the mounting plate 320 opposite to the first support plate 330 in the first direction Y.

[0034] In some implementations, when the seatbelt is not subjected to external force, the coil spring inside the retraction device 200 is in a pre-tensioned state, which drives the reel to rotate, thereby retracting the seatbelt and winding it onto the reel, keeping the seatbelt taut. When the occupant pulls the seatbelt, the seatbelt drives the reel to rotate in the opposite direction. At this time, the coil spring is further twisted, accumulating elastic potential energy, while the internal locking mechanism will not trigger the locking at normal pulling speeds. Once the vehicle encounters emergency braking, a collision, or if the seatbelt is pulled out quickly, the locking mechanism will respond quickly and lock the reel, preventing the seatbelt from being pulled out further, thus firmly restraining the occupant in the seat and providing protection. After the occupant releases the restraint (e.g., by unfastening the seatbelt buckle), the coil spring releases its elastic potential energy, driving the reel to rotate forward, retracting and winding the seatbelt again.

[0035] In some implementations, refer to Figure 1 The included angle between the first plate 311 and the second plate 312 is set according to actual needs. The wheel cover 100 includes a main body and an extension portion extending in the first direction Y. The first plate 311 and the second plate 312 are respectively connected to the main body and the extension plate, further enhancing the connection strength between the reinforcing plate 310 and the wheel cover 100 plate. The mounting plate 320 has a flat mounting surface, which is connected to the bottom of the winding device 200. The telescopic end 210 of the winding device 200 is located on the side of the mounting plate 320 opposite to the first plate 311 in the first direction Y.

[0036] In some embodiments, the reinforcing plate 310, mounting plate 320, first support plate 330, and second support plate 340 can be made of steel, formed by bending and cutting a whole steel plate, or formed from waste materials generated during vehicle manufacturing through bending and cutting processes. This design enables waste material utilization and saves material costs. Steel has high tensile strength and yield strength, effectively resisting the impact force generated when the seat belt is stretched, ensuring that the mounting bracket is not prone to deformation or breakage during long-term use. When bending and cutting a whole steel plate, precise forming can be achieved through stamping dies, ensuring the connection angle and dimensional accuracy between the plates and improving the overall structural stability of the mounting bracket. Utilizing waste materials generated during vehicle manufacturing reduces raw material input and production energy consumption, aligning with the trend of green manufacturing. For example, scraps generated during the body stamping process can be screened and used as raw materials for the mounting bracket. Impurities are removed by laser cutting, and then processed by CNC bending machines into the required reinforcing plates, mounting plates, and other structures, improving material utilization and reducing manufacturing costs. At the same time, this integrated molding process can reduce welding and other connection processes, avoid stress concentration problems caused by welding defects, and further enhance the structural reliability of the mounting bracket.

[0037] In some implementations, refer to Figure 2 The mounting bracket 300 includes a third support plate 350, which and the first support plate 330 are spaced apart in a second direction X intersecting the first direction Y. One end of the third support plate 350 is connected to the side of the mounting plate 320 facing the first plate body 311, and the other end extends towards the wheel cover 100 and is connected to the side of the first plate body 311 facing the mounting plate 320. This arrangement can provide multi-point support for the mounting plate 320 in the second direction X, effectively dispersing the lateral load generated when the winding device 200 is working, and reducing the risk of deformation of the mounting plate 320 under long-term stress.

[0038] In some implementations, combined with Figure 3 The third support plate 350 includes a first flange 351 and a second flange spaced apart in the first direction Y. The first flange 351 is connected to the mounting plate 320, and the second flange is connected to the first plate body 311. The first flange 351 and the mounting plate 320, and the second flange and the first plate body 311, can be fixed by welding and / or riveting to ensure that the third support plate 350 does not loosen during force transmission. This structural design allows the third support plate 350 to work in conjunction with the first support plate 330 to jointly construct a stable support system in the first direction Y and the second direction X, further improving the overall deformation resistance of the mounting bracket 300. When the winding device 200 is subjected to forces from different directions during operation, the first flange 351 and the second flange of the third support plate 350 can respectively transmit part of the force to the mounting plate 320 and the first plate body 311, avoiding excessive stress concentration at a single connection point, thereby extending the service life of the mounting bracket 300. Furthermore, the spacing between the first flange 351 and the second flange in the first direction Y can be adjusted according to the actual stress and installation space to meet the structural strength requirements of the mounting bracket 300 for different vehicle models. Specifically, the first flange 351 and the second flange are formed on both sides of the first main body plate through a bending process, and the first flange 351, the second flange and the first main body plate are an integral structure.

[0039] In some implementations, combined Figure 4The first support plate 330 includes a third flange 331, a fourth flange 332, and a fifth flange 333. The third flange 331 and the fourth flange 332 are spaced apart in the first direction Y. The third flange 331 is connected to the mounting plate 320, the fourth flange 332 is connected to the first plate body 311, and the fifth flange 333 connects the third flange 331, the fourth flange 332, and the second plate body 312. The third flange 331 and the mounting plate 320, the fourth flange 332 and the first plate body 311, and the fifth flange 333 and the second plate body 312 can be fixed by welding and / or riveting to enhance the stability of the connection and ensure that the first support plate 330 can effectively transmit the force between the mounting plate 320 and the first plate body 311. The fifth flange 333 further strengthens the connection between the third flange 331, the fourth flange 332, and the second plate 312, forming a stable support structure. This allows the first support plate 330 to distribute the force more evenly to various parts of the reinforcing plate 310 when subjected to tension from the winding device 200, preventing excessive local stress from causing structural damage. This multi-flanged design not only improves the structural strength of the first support plate 330 itself but also optimizes the overall stress performance of the mounting bracket 300, thereby better ensuring the installation stability of the winding device 200. Specifically, the third flange 331, the fourth flange 332, and the fifth flange 333 are formed on multiple sides of the second main plate through a bending process, and the third flange 331, the fourth flange 332, the fifth flange 333, and the second main plate form an integrated structure.

[0040] In some implementations, combined Figure 5 The mounting plate 320 includes a sixth flange 321 extending along the first direction Y toward the first support plate 330. The sixth flange 321 connects to the second support plate 340, and the sixth flange 321 and the second support plate 340 are stacked in the second direction X, which is perpendicular to the first direction Y. (See reference...) Figure 6 The second support plate 340 includes a first connecting plate 341 and a second connecting plate 342 arranged at an angle. The first connecting plate 341 connects to the sixth flange 321, and the second connecting plate 342 connects to the second plate body 312. The second support plate 340 also includes a third connecting plate 343, which connects the first connecting plate 341, the second connecting plate 342, and the second plate body 312. Specifically, the sixth flange 321 is formed on the third main plate through a bending process, and the sixth flange 321 and the third main plate are an integral structure.

[0041] In some implementations, combined Figure 5 and Figure 6The first connecting plate 341 is fixed to the sixth flange 321 by welding and / or riveting, and the second connecting plate 342 is also fixed to the third flange 331 of the first support plate 330 by welding and / or riveting. This dual connection method can further enhance the connection strength between the second support plate 340 and the mounting plate 320 and the first support plate 330. At the end of the second connecting plate 342 away from the first connecting plate 341, a third connecting plate 343 is integrally formed. The third connecting plate 343 extends towards the wheel cover 100 and abuts against the second plate body 312. Through the cooperation of the third connecting plate 343 and the second plate body 312, the second support plate 340 forms a multi-directional support structure, effectively dispersing the stress generated by the winding device 200 when subjected to tension, and preventing deformation or breakage of the mounting bracket 300 in a local area due to stress concentration. In addition, a rubber buffer pad is provided between the third connecting plate 343 and the second plate 312, which can absorb some vibration energy during vehicle operation, reduce rigid collision between the mounting bracket 300 and the wheel cover 100, reduce the probability of abnormal noise, and extend the service life of each component.

[0042] In some implementations, combined with Figure 5 and Figure 7 The winding device 200 forms a limiting groove 220, and the mounting plate 320 forms a limiting protrusion 322, with the limiting protrusion 322 located within the limiting groove 220. Both the limiting groove 220 and the limiting protrusion 322 are formed by stamping. The limiting groove 220 is formed at the bottom of the winding device 200 and recessed into the interior of the winding device 200, while the limiting protrusion 322 is formed on the mounting plate 320 and protrudes towards the winding device 200. At least a portion of the limiting protrusion 322 can be located within the limiting groove 220; the interaction between the two reduces the risk of abnormal noise from the winding device 200 during vehicle movement.

[0043] In some implementations, combined Figure 5 and Figure 7 The winding device 200 includes a locking portion 230, and a mounting plate 320 forms a locking hole 323, within which the locking portion 230 engages. The locking portion 230 bends towards the mounting plate 320 to form a hook, which can extend into the locking hole 323 to engage with the mounting plate 320. Specifically, the locking portion 230 is located on the side of the limiting groove 220 opposite to the telescopic end 210. When the winding device 200 is stretched, the locking portion 230 maintains the stability of the winding device 200 through its engagement with the locking hole 323. Furthermore, the mounting plate 320 and the winding device 200 are also connected by threads to enhance their connection stability.

[0044] In this application, the wheel cover 100 has an arc-shaped semi-enclosed structure with a mounting surface on top. The winding device 200 is located on the side of the mounting plate 320 away from the first support plate 330. The mounting bracket 300 includes a reinforcing plate 310, a mounting plate 320, a first support plate 330, a second support plate 340, and a third support plate 350. The first plate body 311 and the second plate body 312 of the reinforcing plate 310 are connected to the wheel cover 100 and the mounting plate 320 at an included angle. The mounting plate 320 and the first plate body 311 are spaced apart to improve installation convenience. The first support plate 330 and the third support plate 350 are located between the first plate body 311 and the mounting plate 320. The side away from the telescopic end 210 is connected to the first support plate 330 and the mounting plate 320 through the second support plate 340. This design can enhance the structural strength and reduce the risk of breakage.

[0045] This application also provides a vehicle including the aforementioned vehicle body.
