Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a spare tire mounting structure and a vehicle. Background Technology

[0002] In related technologies, the spare tire is typically mounted on the tailgate via a spare tire bracket, and the tailgate mainly consists of an inner panel and an outer panel. Furthermore, to ensure the strength of the spare tire mounting, a reinforcing plate is usually installed between the inner and outer panels of the tailgate, with the spare tire mounting point located on this reinforcing plate. However, even with a relatively thick reinforcing plate, the strength and rigidity at the spare tire mounting point are still relatively weak. This results in severe tailgate vibration during vehicle operation, especially on bumpy roads, which can easily lead to dust entering the tailgate and causing abnormal noises. Utility Model Content

[0003] In view of this, this application aims to provide a spare tire mounting structure to improve the strength and rigidity of the spare tire mounting location.

[0004] To achieve the above objectives, the technical solution of this application is implemented as follows: A spare tire mounting structure includes a crash bar assembly and a spare tire mounting part disposed between the inner and outer panels of the tailgate. The anti-collision bar assembly extends along the width direction of the tailgate and connects between the two ends of the inner panel. The spare tire mounting part is connected to the inner panel and the anti-collision bar assembly.

[0005] Furthermore, the anti-collision bar assembly includes two anti-collision bars spaced apart along the height direction of the rear door; The spare tire mounting section includes two mounting plates spaced apart along the height direction of the tailgate, and the two mounting plates are connected to the two anti-collision bars in a one-to-one correspondence.

[0006] Furthermore, at least one of the mounting plates includes a main body protruding toward the outer plate and a flange disposed at the edge of the main body, the flange being connected to the inner plate and the anti-collision bar; The main body abuts against the outer panel, and a spare tire mounting hole is provided on the main body. The main body also has a recessed portion that is recessed into one side of the inner panel, and the recessed portion is connected to the anti-collision bar.

[0007] Furthermore, two reinforcing plates are connected between the two anti-collision bars; The two reinforcing plates are arranged at intervals along the width direction of the rear door, and the two reinforcing plates are respectively located on both sides of the spare tire mounting part.

[0008] Furthermore, at least one of the reinforcing plates abuts against the outer plate; At least one of the reinforcing plates is provided with a buffer block mounting part, which is used to install a buffer block that abuts against the spare tire.

[0009] Furthermore, the inner panel has a door lock reinforcing plate at its first end and a hinge reinforcing plate at its second end; From the second end to the first end of the inner plate, the distance between the two anti-collision bars gradually increases.

[0010] Furthermore, the door lock reinforcing plate extends along the height direction of the inner plate; Viewed from the front and rear direction of the rear door, at least part of the door lock reinforcement plate is located between the two anti-collision bars.

[0011] Furthermore, the anti-collision bar assembly includes a support plate disposed between the two anti-collision bars; The support plate is disposed near the first end of the inner plate, and the support plate has a protruding portion that protrudes toward the outer plate, the protruding portion abutting against the outer plate.

[0012] Furthermore, the hinge reinforcement plate extends along the height direction of the inner plate; The anti-collision bar assembly includes a first bracket disposed on one of the anti-collision bars and a second bracket disposed on the other anti-collision bar, wherein the first bracket is connected to both the hinge reinforcement plate and the inner plate, and the second bracket is connected to both the hinge reinforcement plate and the inner plate.

[0013] Compared with related technologies, this application has the following advantages: (1) The spare tire mounting structure described in this application can directly enhance the overall structural strength of the rear door by taking advantage of the excellent structural strength characteristics of the anti-collision bar assembly itself, effectively improve the anti-deformation ability of the rear door during the load-bearing process, and thus improve the overall load-bearing performance of the rear door, which is conducive to providing a stable mounting foundation for the spare tire.

[0014] In addition, by connecting the spare tire mounting section to the inner panel and the anti-collision bar assembly, the structural strength and rigidity of the spare tire mounting position can be improved by taking advantage of the excellent structural strength characteristics of the anti-collision bar assembly itself. This can effectively avoid the problem of vibration and abnormal noise in the tailgate caused by insufficient strength of the spare tire mounting point during vehicle operation.

[0015] (2) By setting two anti-collision bars at intervals, it can not only effectively resist the torsional force in the left and right directions of the tailgate, but also effectively avoid the bending deformation of the tailgate due to uneven force on the top and bottom. The spare tire mounting part includes two mounting plates that are connected to the two anti-collision bars one by one, so that the strength of each mounting point of the spare tire is rigidly supported by the anti-collision bars, which is conducive to improving the overall installation strength and rigidity of the spare tire.

[0016] (3) By making the mounting plate include a main body protruding outwards and a flange located at the edge of the main body, the mounting plate can have better structural strength, which can improve the strength and rigidity at the spare tire mounting point. In addition, by providing a recessed part on the main body that is connected to the anti-collision bar, the overall structural strength of the mounting plate can be further improved, and the connection strength and connection area between the mounting plate and the anti-collision bar can also be increased.

[0017] (4) By setting two reinforcing plates, they can share the external force with the two anti-collision bars. When facing the vertical impact generated by the bumpy road surface, the reinforcing plates can pull the upper and lower anti-collision bars simultaneously, reducing the relative displacement between the two. With the two reinforcing plates located on both sides of the spare tire mounting part, the load of the spare tire transmitted to the anti-collision bars through the mounting plate can be dispersed and dissipated by the two reinforcing plates at the same time, which can effectively prevent the inner plates or anti-collision bars on both sides of the mounting part from cracking or deforming due to excessive local stress.

[0018] (5) By making the reinforcing plate abut against the outer panel, the overall dent resistance of the tailgate can be improved, which is beneficial to improving the overall load-bearing capacity of the tailgate. By setting a buffer block mounting part on the reinforcing plate, the installation strength of the buffer block can be improved by taking advantage of the excellent rigidity performance of the anti-collision bar, which can have good contact stability with the spare tire and help avoid direct collision between the spare tire and the outer panel. Moreover, there is no need to set an additional mounting plate for installing the buffer block.

[0019] (6) By increasing the spacing of the area closer to the door lock side, the anti-collision bar can provide a wider range of support for the height of the tailgate, and can distribute the load around the door lock reinforcement plate to a wider area, avoiding local stress overload. The area with smaller spacing is closer to the hinge side, and can achieve stable load transfer through the high rigidity of the hinge reinforcement plate and the compact anti-collision bar layout, which can further improve the overall deformation resistance of the inner panel and strengthen the overall structural stability of the tailgate.

[0020] (7) When viewed from the front and rear direction of the rear door, at least part of the door lock reinforcement plate is located between the two anti-collision bars, so that at least part of the door lock reinforcement plate is located within the support range of the anti-collision bars on the rear door. When the door lock is subjected to closing impact, the anti-collision bars can distribute the impact force to other areas of the inner panel through a wider support range, thereby effectively avoiding the door lock reinforcement plate being overloaded by the force alone, which is conducive to extending the service life of the lock body.

[0021] (8) By setting the support plate close to the first end, that is, close to the door lock reinforcement plate, and connecting it between the two anti-collision bars, the longitudinal connection strength can be further increased on the basis of the lateral support formed by the anti-collision bars, which can weaken the overall support effect on the back door caused by the increased distance between the two anti-collision bars.

[0022] (9) By setting the first bracket and the second bracket, it is convenient to connect the two anti-collision bars to the inner plate, and it is also convenient to arrange the anti-collision bars. Connecting the first bracket and the second bracket to the hinge reinforcement plate and the inner plate respectively can improve the structural strength of the hinge position and enhance the installation stability of the hinge. At the same time, it can also make the load transmitted by the anti-collision bars simultaneously transferred to the hinge reinforcement plate and the inner plate for dissipation, which can effectively prevent the inner plate from cracking and deforming.

[0023] Another object of this application is to provide a vehicle having a spare tire mounting structure as described above.

[0024] The vehicle described in this application, by setting the spare tire mounting structure as described above, can make the spare tire mounting position have high strength and rigidity, which can effectively avoid the problem of vibration and abnormal noise in the tailgate caused by insufficient strength of the spare tire mounting point during vehicle operation, thus improving the overall vehicle quality and driving experience.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0033] An embodiment of the first aspect of this application provides a spare tire mounting structure to improve the strength and rigidity of the spare tire mounting location.

[0034] In related technologies, spare tires are typically mounted on the tailgate of a vehicle using a mounting bracket to avoid occupying the trunk storage area. Specifically, the main structure of the tailgate consists of an inner panel 11 and an outer panel. Considering the weight of the spare tire itself, to prevent deformation or damage to the spare tire mounting location, related technologies generally add a reinforcing plate between the inner panel 11 and the outer panel of the tailgate, and place the spare tire mounting point directly on this reinforcing plate. This structural support of the reinforcing plate enhances the strength of the spare tire mounting location.

[0035] However, the inventors discovered during practical application that even with thicker reinforcing plates, the strength and rigidity of the spare tire mounting area still failed to meet usage requirements. Especially during vehicle operation, when encountering bumpy road conditions, the spare tire and tailgate experience significant vibrations due to road impacts, and the insufficient strength and rigidity of the spare tire mounting point exacerbates tailgate shaking. This not only compromises the seal between the inner and outer panels of the tailgate, allowing dust to easily enter and contaminate internal components, but also causes friction and collision between components, generating abnormal noise and significantly impacting the user's driving experience.

[0036] In view of this, in order to overcome the shortcomings of the related technology, the spare tire mounting structure of this embodiment combines... Figures 1 to 4 As shown, the overall design includes a crash bar assembly and a spare tire mounting part located between the inner panel 11 and the outer panel of the tailgate. The crash bar assembly extends along the width direction of the tailgate and connects the two ends of the inner panel 11. The spare tire mounting part is located on the inner panel 11 and is connected to the crash bar assembly.

[0037] Therefore, by setting a crash bar assembly between the inner panel 11 and the outer panel of the tailgate, and connecting the crash bar assembly between the two ends of the inner panel 11, the excellent structural strength characteristics of the crash bar assembly itself can directly enhance the overall structural strength of the tailgate, effectively improve the tailgate's resistance to deformation during load-bearing, and thus improve the overall load-bearing performance of the tailgate, which is conducive to providing a stable installation foundation for the spare tire.

[0038] In addition, by connecting the spare tire mounting section to the inner panel 11 and the anti-collision bar assembly, the inner panel 11 can provide a basic fixing point for the spare tire mounting section, and the anti-collision bar assembly can provide an additional rigid support structure for the spare tire mounting section. By taking advantage of the excellent structural strength characteristics of the anti-collision bar assembly itself, the structural strength and rigidity of the spare tire mounting position can be improved, thereby effectively avoiding the problem of vibration and abnormal noise in the tailgate caused by insufficient strength of the spare tire mounting point during vehicle operation.

[0039] Based on the above overview, specifically, the rear door in this embodiment is a side-opening rear door, and its overall structure is the same as related technologies. Wherein, as... Figure 1 As shown, the inner panel 11 of the tailgate has multiple perforations spaced apart along its width in the middle to reduce overall weight and provide operating space for the installation of components such as door locks. In order to ensure the overall structural strength of the tailgate, the anti-collision bar assembly in this embodiment is generally positioned at the perforations to mitigate the impact of the perforations on the structural strength of the inner panel 11. It should be noted that this embodiment only shows a partial structure of the inner panel 11 of the rear door, and does not show the outer panel of the rear door. The specific structure can be referred to in the relevant technology, and will not be described in detail here.

[0040] Continue to combine Figures 1 to 3 As shown, in some exemplary embodiments, the bumper assembly includes two bumpers spaced apart along the height of the tailgate. The spare tire mounting section includes two mounting plates spaced apart along the height of the tailgate, and the two mounting plates are connected to the two bumpers in a one-to-one correspondence. For ease of explanation, the upper bumper is referred to as "first bumper 1", and the lower bumper is referred to as "second bumper 2".

[0041] At this point, by setting up two anti-collision bars at intervals, the excellent bending and torsional deformation resistance of the anti-collision bars themselves can be utilized. Not only can each anti-collision bar provide lateral support in the width direction for the tailgate, resisting the torsional force in the left and right directions of the tailgate, but the spacing of the two anti-collision bars in the height direction can also provide longitudinal bending resistance support for the tailgate, preventing bending deformation caused by uneven force on the tailgate from top to bottom.

[0042] In addition, the spare tire mounting section includes two mounting plates that are connected one-to-one with the two anti-collision bars. This ensures that the strength of each mounting point of the spare tire is rigidly supported by the anti-collision bars, which helps to improve the overall installation strength and rigidity of the spare tire. This effectively ensures the stability of the spare tire during driving and reduces the risk of the tailgate shaking and abnormal noise caused by the swaying of the spare tire.

[0043] In specific implementation, combined with Figures 2 to 4 As shown, in this embodiment, both ends of the two anti-collision bars are connected to the left and right ends of the inner panel 11, and each anti-collision bar is hollow inside with a circular cross-section, that is, the anti-collision bar is a circular tube. With this structure, when subjected to external forces such as loads transmitted from the spare tire and lateral impacts from bumps, the stress of the anti-collision bars is evenly distributed along their circumference, effectively avoiding local overload problems such as stress concentration. This provides more reliable lateral support for the tailgate and further strengthens the overall structural rigidity. Moreover, the circular anti-collision bars are easier to manufacture, reducing the production cost of the tailgate.

[0044] It should be noted that, in addition to two spaced apart along the height of the tailgate, the bumper bars can also be three or more spaced apart, or even just one. Furthermore, the cross-section of the bumper bar can be circular, rectangular, or other shapes.

[0045] In some exemplary embodiments, at least one mounting plate includes a main body protruding outward from the outer plate and a flange located at the edge of the main body, the flange being connected to the inner plate 11 and the anti-collision bar. Furthermore, the main body abuts against the outer plate and has a spare tire mounting hole M, and the main body has a recessed portion N recessed towards one side of the inner plate 11, the recessed portion N being connected to the anti-collision bar.

[0046] By including a main body protruding outwards from the outer panel and a flange at the edge of the main body, the mounting plate not only possesses better structural strength, improving the strength and rigidity at the spare tire mounting point, but also, by abutting the main body against the outer panel, it provides support for the outer panel, preventing it from denting towards the inner panel 11 and thus enhancing the overall stability of the tailgate. Simultaneously, the flange facilitates the connection between the mounting plate and the inner panel 11 and the anti-collision bar.

[0047] In addition, by setting a recessed portion N on the main body that is connected to the anti-collision bar, the overall structural strength of the mounting plate can be further improved, and the connection strength and connection area between the mounting plate and the anti-collision bar can be increased. This facilitates the better transfer of the load of the spare tire carried by the mounting plate to the anti-collision bar for dispersion and dissipation, thereby effectively preventing the mounting plate from deforming and being damaged.

[0048] Combination Figure 2 and Figure 3 As shown in the illustration, in a preferred embodiment, the two mounting plates in this embodiment have substantially the same structure, and both include a main body protruding outwards and a flange located at the edge of the main body. Furthermore, for ease of explanation, based on... Figure 2 As shown in the diagram, the upper mounting plate is referred to as "first mounting plate 3", and the lower mounting plate is referred to as "second mounting plate 4".

[0049] The structure of the first mounting plate 3 is referenced. Figure 5 and Figure 6 As shown, the upper and left / right sides are provided with outward-folding flanges, with the upper flange connected to the inner plate 11, and the left / right flanges connected to the first anti-collision bar 1. Furthermore, to further improve the installation strength and rigidity of the spare tire, a boss protruding towards one side of the outer plate is provided on the main body. Simultaneously, two spare tire mounting holes M are spaced apart on the boss, and each spare tire mounting hole M constitutes one mounting point for the spare tire.

[0050] Furthermore, the boss supports the outer panel, providing good support for it. Additionally, the recessed portion N is approximately located in the middle of the main body's length and extends to the boss; simultaneously, the two spare tire mounting holes M are located on either side of the recessed portion N. This further enhances the structural strength of the first mounting plate 3 and provides additional reinforcement at each spare tire mounting hole M. Consequently, the installation strength and rigidity at the spare tire mounting point are improved. The structure of the second mounting plate 4 is as follows... Figure 7 As shown, its overall shape is the same as that of the first mounting plate 3, the main difference being that the bottom of the second mounting plate 4 has a notch in the middle.

[0051] It is understandable that the number of mounting holes is not limited to those shown in the diagram, and can be adjusted according to design requirements. Alternatively, the boss can be omitted, allowing the end face of the main body to directly abut against the outer panel.

[0052] In some exemplary embodiments, two reinforcing plates connect the two bumper bars, and the two reinforcing plates are spaced apart along the width of the tailgate, with each reinforcing plate located on either side of the spare tire mounting area. By providing two reinforcing plates, they can share the external force with the two bumper bars. When facing vertical impacts from bumpy roads, the reinforcing plates can simultaneously pull the upper and lower bumper bars, reducing their relative displacement and further enhancing the overall stability of the tailgate structure.

[0053] In addition, by placing two reinforcing plates on both sides of the spare tire mounting section, the load transmitted from the spare tire to the crash bar through the mounting plates can be simultaneously dispersed and dissipated by the two reinforcing plates, which can effectively prevent the inner plates 11 on both sides of the mounting section or the crash bar from cracking or deforming due to excessive local stress.

[0054] In some exemplary embodiments, at least one reinforcing plate abuts against the outer panel, and at least one reinforcing plate is provided with a buffer block mounting portion for mounting a buffer block that abuts against the spare tire. By having the reinforcing plate abut against the outer panel, the overall dent resistance of the tailgate can be improved, which is beneficial to improving the overall load-bearing capacity of the tailgate.

[0055] By incorporating a buffer block mounting component on the reinforcing plate, the excellent rigidity of the anti-collision bar enhances the installation strength of the buffer block, providing better contact stability for the spare tire and preventing direct collisions between the spare tire and the outer panel. Furthermore, eliminating the need for an additional mounting plate for the buffer block reduces the number of components, facilitating a lighter overall design for the tailgate and lowering manufacturing costs.

[0056] Combination Figures 2 to 4 As shown, based on Figure 2 As shown in the diagram, the reinforcing plate on the right is referred to as "first reinforcing plate 5," and the reinforcing plate on the left is referred to as "second reinforcing plate 6." The structure of the first reinforcing plate 5 is as follows: Figure 8 As shown, the design extends along the height of the rear door. The cross-section of the first reinforcing plate 5 is generally Z-shaped, with a main body protruding to one side of the outer panel and connecting edges on the upper and lower sides of the main body. The connecting edges on both sides are welded to the first anti-collision bar 1 and the second anti-collision bar 2, respectively. At the same time, a buffer block fixing hole P is provided on the main body.

[0057] The structure of the second reinforcing plate 6 is referenced. Figure 9 and Figure 10As shown, it includes a first plate 601 and a second plate 602 welded together. The first plate 601 is generally box-shaped, with four connecting edges specifically arranged along its perimeter. The upper connecting edge is welded to the inner plate 11, the left and right connecting edges are welded to the first anti-collision bar 1, and the lower connecting edge is welded to the second plate 602. Furthermore, the first plate 601 abuts against the outer plate, and a buffer block fixing hole P is provided on the first plate 601.

[0058] like Figure 10 As shown, the side of the second plate 602 away from the first plate 601 protrudes towards the inner plate 11. This arrangement not only improves the overall structural strength of the second reinforcing plate 6, but also provides mounting points for other components. Furthermore, as... Figure 2 As shown, a third reinforcing plate 10, corresponding to the second reinforcing plate 6, is welded onto the second anti-collision bar 2. Furthermore, the third reinforcing plate 10 is generally box-shaped to provide good structural strength and allow it to abut against the outer plate. Additionally, the third reinforcing plate 10 is provided with holes P for mounting buffer blocks.

[0059] This allows the buffer block fixing holes P on the three reinforcing plates to be arranged in a triangle. The triangle's good stability can be used to improve the buffering effect on the spare tire and effectively prevent the spare tire from colliding with the outer plate and causing abnormal noise.

[0060] In some exemplary embodiments, the inner panel 11 has a door lock reinforcing plate 8 at its first end and a hinge reinforcing plate 9 at its second end, with the distance between the two anti-collision bars gradually increasing from the second end to the first end of the inner panel 11. This arrangement allows the area with increased distance to be closer to the door lock side, enabling the anti-collision bars to provide wider support in the height direction of the rear door, and distributing the load around the door lock reinforcing plate 8 to a wider area, thus avoiding localized stress overload.

[0061] In areas with smaller spacing, closer to the hinge side, the high rigidity of the hinge reinforcement plate 9 and the compact anti-collision bar layout can achieve stable load transfer, further improving the overall deformation resistance of the inner panel 11 and strengthening the overall structural stability of the rear door.

[0062] Among them, such as Figure 1 As shown in the illustration, in a specific embodiment, the hinge reinforcement plate 9 is located on the right side of the inner panel 11, while the door lock reinforcement plate 8 is located on the left side of the inner panel 11. That is to say, based on the vehicle's own orientation, the first end is the left end of the tailgate, and the second end is the right end of the tailgate.

[0063] It should be noted that, in addition to placing the hinge reinforcement plate 9 on the right side of the inner panel 11, the hinge reinforcement plate 9 can also be placed on the left side of the inner panel 11 and the door lock reinforcement plate 8 can be placed on the right side of the inner panel 11, depending on the design requirements.

[0064] In some exemplary embodiments, the door lock reinforcement plate 8 extends along the height direction of the inner panel 11, and at least a portion of the door lock reinforcement plate 8 is located between the two anti-collision bars when viewed from the rear-end direction of the tailgate. This arrangement ensures that at least a portion of the door lock reinforcement plate 8 is within the support range of the anti-collision bars for the tailgate, further preventing localized stress overload in the area of ​​the door lock reinforcement plate 8. Here, the rear-end direction of the tailgate refers to the preferred rear-end direction when the tailgate is closed, which is consistent with the overall vehicle rear-end direction.

[0065] Therefore, when the door lock is subjected to closing impact, the anti-collision bar can distribute the impact force to other areas of the inner plate 11 through a wider support range, which can effectively prevent the door lock reinforcing plate 8 from being overloaded alone, while reducing fatigue damage at the connection point between the door lock and the inner plate 11, which helps to extend the service life of the lock body.

[0066] In specific implementation, such as Figure 11 As shown, the first anti-collision bar 1 and the second anti-collision bar 2 are arranged in a roughly "V" shape. Additionally, the structure of the door lock reinforcing plate 8 is as follows... Figure 12 As shown, its cross-section is approximately L-shaped and includes a first part and a second part that are bent and connected together. The first part is welded to the large surface of the inner plate 11, while the second part is welded to the side surface of the inner plate 11.

[0067] In addition, such as Figure 12 As shown, the upper part of the second section has three door lock mounting holes 801 arranged in a triangle, while the lower part has two limit block mounting holes 802 arranged at intervals. Furthermore, as... Figure 2 As shown, most of the door lock reinforcing plate 8 is located between the first anti-collision bar 1 and the second anti-collision bar 2, so as to better prevent local stress overload in the area of ​​the door lock reinforcing plate 8.

[0068] In some exemplary embodiments, the anti-collision bar assembly includes a support plate 7 disposed between two anti-collision bars. The support plate 7 is positioned near a first end of the inner panel 11 and has a protruding portion extending towards the outer panel, which abuts against the outer panel. By positioning the support plate 7 near the first end, i.e. near the door lock reinforcing plate 8, and connecting it between the two anti-collision bars, the longitudinal connection strength is further increased on top of the lateral support formed by the anti-collision bars, thus mitigating the reduced overall support effect on the rear door caused by the increased distance between the two anti-collision bars.

[0069] In addition, by having the protruding part of the support plate 7 abut against the outer plate, the concentrated load on the door lock side can be transferred to the outer plate simultaneously, avoiding the inner plate 11 and the door lock reinforcing plate 8 from bearing overload alone. This can improve the impact resistance of the high-stress area and help ensure the overall structural strength of the back door.

[0070] In specific implementation, it can be as follows: Figure 13 and Figure 14 As shown, the support plate 7 is arranged in a Z-shape, with a central portion arching outwards to one side, and side portions located on the upper and lower sides of the central portion. Each side portion has a groove conforming to the shape of a corresponding anti-collision bar, and is welded to the corresponding anti-collision bar through these grooves. Furthermore, as... Figure 13 As shown, a plurality of glue grooves 701 are provided in the middle part of the support plate 7 that abuts against the outer plate. The glue grooves 701 are used to fill the expanding glue that is in contact with the outer plate, thereby further improving the support effect on the outer plate and improving the outer plate's resistance to dents and bulges.

[0071] It is understood that, in addition to placing the support plate 7 near the first end, the support plate 7 can also be placed near the second end, or support plates 7 can be placed between the first and second ends of both anti-collision bars. Moreover, the number of support plates 7 is not limited to that shown in the figure, and can be adjusted according to design requirements.

[0072] In some exemplary embodiments, the hinge reinforcement plate 9 extends along the height direction of the inner panel 11. The bumper assembly includes a first bracket 12 mounted on one bumper and a second bracket 13 mounted on the other bumper. The first bracket 12 is connected to both the hinge reinforcement plate 9 and the inner panel 11, and the second bracket 13 is also connected to both the hinge reinforcement plate 9 and the inner panel 11. By extending the hinge reinforcement plate 9 along its height, it achieves better rigidity and a larger load-bearing area, thereby distributing the load along the height direction to the inner panel 11 and the vehicle body hinges. This effectively addresses the problem of localized stress concentration, reducing the risk of cracking of the inner panel 11 and loosening of connection points.

[0073] By setting the first bracket 12 and the second bracket 13, it is easy to connect the two anti-collision bars to the inner plate 11. The larger area of ​​the first bracket 12 and the second bracket 13 increases the connection area between the anti-collision bars and the inner plate 11, and also facilitates the arrangement of the anti-collision bars. Connecting the first bracket 12 and the second bracket 13 to both the hinge reinforcement plate 9 and the inner plate 11 further improves the structural strength at the hinge location, enhancing the installation stability of the hinge. Simultaneously, it allows the load transmitted by the anti-collision bars to be simultaneously transferred to the hinge reinforcement plate 9 and the inner plate 11 for dissipation, effectively preventing cracking and deformation of the inner plate 11.

[0074] On the other hand, the load on the hinge can be dissipated by the anti-collision bar, which can effectively prevent the hinge reinforcement plate 9 from cracking and deforming, thereby ensuring the installation stability of the hinge and thus helping to ensure the smooth opening of the tailgate.

[0075] In specific implementation, it can be as follows: Figure 15 As shown, the hinge reinforcement plate is L-shaped and includes a main plate portion 9b and a side plate portion 9a that are bent and connected. The main plate portion 9b is stepped and welded to the large surface of the inner plate 11, while the side plate portion 9a is welded to the side surface of the inner plate 11. Additionally, two hinge mounting plates 901 are provided on the side plate portion 9a, spaced vertically apart, and each hinge mounting plate 901 has a hinge mounting hole penetrating the inner plate 11. These two hinge mounting plates 901 can be used to install the upper hinge and the lower hinge of the rear tailgate, respectively.

[0076] Combination Figure 2 and Figure 11 As shown, this embodiment has the same structure as the first bracket 12 and the second bracket 13, and both are Z-shaped. One end face of the first bracket 12 and the second bracket 13 is welded to the corresponding anti-collision bar, and the other end face is welded to the main board portion 9b of the hinge reinforcement plate 9. Furthermore, as a preferred embodiment, such as... Figure 11 In this configuration, a third bracket 14 is provided at the other end of the first anti-collision bar 1, and is welded to the inner plate 11 via the third bracket 14. Simultaneously, a fourth bracket 15 is provided at the other end of the second anti-collision bar 2, and is welded to the inner plate 11 via the fourth bracket 15.

[0077] It is worth noting that, regarding the spare tire mounting structure of this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still [structured using...]. Figures 1 to 15 As shown, it may include, for example, a bumper assembly and a spare tire mounting portion disposed between the inner panel 11 and the outer panel of the tailgate. The bumper assembly extends along the width direction of the tailgate and is connected between the two ends of the inner panel 11. The spare tire mounting portion is connected to the inner panel 11 and the bumper assembly.

[0078] The anti-collision bar assembly includes two anti-collision bars spaced apart along the height direction of the tailgate, and a support plate 7 connected between the two anti-collision bars. The spare tire mounting part includes two mounting plates spaced apart along the height direction of the tailgate, and the two mounting plates are connected to the two anti-collision bars one by one.

[0079] The inner panel 11 has a door lock reinforcing plate 8 at its first end and a hinge reinforcing plate 9 at its second end. The distance between the two anti-collision bars gradually increases from the second end to the first end of the inner panel 11.

[0080] In the preferred embodiment of the above spare tire mounting structure, the specific settings and arrangements of the anti-collision bar assembly, spare tire mounting part, etc. can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the anti-collision bar assembly, spare tire mounting part, etc. can also be referred to the descriptions in the above exemplary embodiments.

[0081] The spare tire mounting structure in this embodiment, with the design described above, improves the structural strength and rigidity of the spare tire mounting point and eliminates the need for a thick reinforcing plate at the mounting point, facilitating lightweight design of the tailgate and the entire vehicle. Furthermore, it effectively prevents vibration and abnormal noise issues in the tailgate caused by insufficient strength at the spare tire mounting point during vehicle operation.

[0082] An embodiment of the second aspect of this application provides a vehicle having the above-described spare tire mounting structure.

[0083] The vehicle in this embodiment, by setting the above-mentioned spare tire mounting structure, effectively avoids the problem of vibration and abnormal noise caused by insufficient strength of the spare tire mounting point in the tailgate during vehicle operation, which helps to improve the overall vehicle quality and driving experience.
