[0002] Generally, a car is equipped with a spare tire, and its specifications are the same as those of the original car tire. The spare tire is usually placed in the spare tire compartment, and a trunk cover is installed on the spare tire compartment to isolate the spare tire compartment and cover the trunk sheet metal, while also ensuring the flatness of the luggage compartment. In related technologies, many new energy vehicles now have no spare tires and use tire repair tools on board to solve the problem of tire leakage. However, many customers who like self-driving tours often face the problem of tire punctures and leakage due to the complex road conditions during the trip. They need to add another spare tire to improve the safety of the trip, and this requires a spare tire installation structure that can well meet such needs.

[0003] Many global vehicle models are exported to various countries and regions, where spare tire regulations vary. For example, spare tires are not mandatory in Europe, the United States, and China, while they are required in Middle Eastern countries. Due to the varying spare tire requirements in different regions and countries, a universal spare tire mounting bracket is needed that can accommodate both vehicles requiring a spare tire and those with mandatory spare tire requirements. Vehicles equipped with a spare tire only need to install this bracket's structural interface; vehicles without a spare tire can remove the bracket without affecting other vehicle functions and features.

[0019] The beneficial effects of the technical solution provided by this application include:

[0020] An embodiment of the present application provides a quick-change spare tire mounting structure and a vehicle. Since the quick-change spare tire mounting structure of the present application is provided with a spare tire mounting bracket, the spare tire mounting bracket includes a support plate covering the trunk storage slot and a fixed bracket located on the top of the support plate, and a mounting hole for mounting the spare tire is opened on the fixed bracket, and the fixed bracket is detachably connected to the support plate; a spare tire reinforcement bracket, the spare tire reinforcement bracket includes a support plate and a reinforcement plate, the support plate and the reinforcement plate are both located at the bottom of the support plate and are both connected to the support plate, and the reinforcement plate is connected to the support plate at one end away from the support plate.

[0021] Therefore, the tray of the quick-change spare tire mounting structure of this application not only covers the trunk storage slot, dividing the vehicle trunk into two independent spaces, but also has a fixed bracket for mounting the spare tire on the top of the tray, which is detachably connected to the tray. When the vehicle model requires a spare tire, a fixed bracket for mounting the spare tire can be added to the tray to meet the user's need for dual spare tires. When the vehicle model does not require a spare tire, the fixed bracket can be removed from the tray. The spare tire reinforcement bracket located at the bottom of the tray utilizes a support plate and a reinforcement plate to enhance the structural rigidity of the spare tire mounting bracket, ensuring that this spare tire mounting structure meets the durability strength requirements for spare tire fixing and the requirements of relevant collision safety regulations.

[0022] Furthermore, the quick-change spare tire mounting structure of the present application is located in the vehicle's trunk area and concealed beneath the trunk lid, eliminating the need for trunk space. This structure is removably secured to the vehicle's crossbeam, rear floorboard crossbeam, and rear panel. This structure fully utilizes the interstitial space between the functional modules beneath the trunk lid, without affecting the layout of existing functional modules, piping, and wiring harnesses. This spare tire mounting structure allows for rapid installation and removal from the vehicle's rear structure.

The top mounting plate and four legs are integrally stamped from steel, making them easy to manufacture. Welding or assembling these together provides a more stable and durable structure.

[0025] The support plate and reinforcement plate of the quick-change spare tire mounting structure of the present application extend along the width direction of the pallet. The support plate and reinforcement plate are located below a plurality of support legs, and the tops of the support plate and reinforcement plate are fixedly connected to the pallet and the support legs by bolts. The support plate and reinforcement plate extend along the width direction of the pallet to support the middle portion between the front and rear ends of the pallet. The top of the middle portion of the pallet is used to install a fixed bracket, so the middle portion of the pallet needs to bear the overall weight of the fixed bracket and the second spare tire mounted on the fixed bracket. The support plate and reinforcement plate are located in the middle portion of the pallet and extend along the width direction of the pallet to enhance the structural strength of the pallet. The tops of the support plate and reinforcement plate are fixedly connected to the pallet and the support legs by bolts, so that the support plate, reinforcement plate, pallet and support legs are connected to form a whole, further improving the structural strength.

[0026] The front end of the support plate of the quick-change spare tire mounting structure of the present application is detachably connected to a front connecting plate via bolts. The front connecting plate is provided with multiple mounting holes for connecting to the vehicle body's crossbeam. The rear end of the support plate is detachably connected to a rear connecting plate via bolts. The rear connecting plate is provided with mounting holes for connecting to the vehicle body's rear panel. The front end of the support plate is detachably connected to the front connecting plate via bolts. The front connecting plate secures the spare tire mounting bracket to the vehicle body's crossbeam, utilizing the vehicle body's crossbeam to provide support for the spare tire mounting bracket. The rear end of the support plate is detachably connected to the rear connecting plate via bolts. The rear connecting plate secures the spare tire mounting bracket to the vehicle body's rear panel, utilizing the vehicle body's rear panel to provide support for the spare tire mounting bracket. Both ends of the support plate are detachably connected to the front and rear connecting plates via bolts, making it easy to remove the support plate when using the first spare tire.

[0027] The quick-change spare tire mounting structure of the present application has a trunk cover plate on top of the tray that covers the tray. The trunk cover plate has an opening for exposing the fixing bracket, and the trunk cover plate is also equipped with an opening cover for closing the opening. The trunk cover plate is used to cover the tray, making the trunk appearance more beautiful. Except for the fixing bracket exposed on the outside of the trunk cover plate, the entire spare tire mounting structure is covered by the trunk cover plate. The trunk cover plate has an opening for exposing the fixing bracket. The fixing bracket is exposed from the opening in the trunk cover plate and is used to install a second spare tire. When the second spare tire is no longer needed, the fixing bracket can be removed from the tray, and the opening in the trunk cover plate can be sealed with the opening cover.

[0028] The perforated cover of the quick-change spare tire mounting structure of the present application is connected to the trunk lid via Velcro or a connecting strap. The bottom of the trunk lid is detachably connected to the support plate via a buckle. Both the trunk lid and the perforated cover are made of flexible sound-absorbing materials. The perforated cover is connected to the trunk lid via Velcro or a connecting strap to prevent the perforated cover from being easily lost after being detached from the trunk lid. When the perforated cover is not in use, it is attached to the trunk lid via Velcro or a connecting strap. The bottom of the trunk lid is detachably connected to the support plate via a buckle, facilitating assembly and disassembly of the trunk lid and the support plate. Both the trunk lid and the perforated cover are made of flexible sound-absorbing materials, which improves the sound insulation performance of the trunk and prevents tire noise from entering the trunk or the cab.

[0029] The vehicle of the present application is provided with a rear body structure, which includes a left rear frame and a right rear frame, and the left rear frame and the right rear frame are connected with a body cross beam, a rear floor cross beam and a body rear panel in sequence from front to rear; and a spare tire mounting structure, the spare tire reinforcing bracket of the spare tire mounting structure is supported on the top of the rear floor cross beam, and the spare tire mounting bracket of the spare tire mounting structure is detachably connected to the body cross beam and the body rear panel, so that the spare tire mounting structure is connected to the rear body structure, which can not only improve the structural strength of the rear body structure, but also provide installation space for the spare tire mounting structure.

[0030] The vehicle of this application has a trunk storage slot located between the spare tire mounting bracket and the rear underfloor cross member. A first spare tire is stored in the trunk storage slot, and a second spare tire is mounted on top of the spare tire mounting bracket. A trunk storage slot for the first spare tire is located between the spare tire mounting bracket and the rear underfloor cross member, and a second spare tire is mounted on top of the spare tire mounting bracket. This means that the vehicle can store both the first and second spare tires simultaneously, meeting the user's dual spare tire needs. The first spare tire can be placed in the trunk storage slot below the trunk lid, while the second spare tire is fixed above the trunk lid. Whether the second spare tire is installed can be determined based on the needs of different countries and regions, providing greater flexibility.

[0031] The spare tire reinforcement bracket of the present application has a buckle at the bottom that inserts into the top of the rear underfloor crossbeam. The top of the rear underfloor crossbeam has a socket that fits the buckle. When the buckle is inserted into the socket, it prevents the spare tire reinforcement bracket from upwardly separating from the rear underfloor crossbeam. The spare tire reinforcement bracket and the rear underfloor crossbeam are connected to each other via the buckle and the socket. When the lower support plate needs to be removed, the bolts connecting the support plate to the front and rear connecting plates are first removed. Then, the buckle of the spare tire reinforcement bracket is moved to the left or right relative to the socket of the rear underfloor crossbeam to a set distance. After the buckle is disengaged, it can be disengaged, avoiding the difficulty of disassembly using bolts or other connection methods. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0043] The embodiments of the present application provide a quick-change spare tire installation structure and vehicle, which can solve the problem in related technologies that passenger vehicles can only meet customers' traditional single spare tire needs, but cannot meet the special needs of some customers for dual spare tires.

[0044] See also Figure 1 and Figure 2 As shown, a first aspect of an embodiment of the present application provides a quick-change spare tire mounting structure, the spare tire mounting structure 100 comprising:

[0045] The spare tire mounting bracket 110 includes a support plate 111 covering the trunk storage slot 260 and a fixing bracket 112 located on the top of the support plate 111. A mounting hole for mounting the second spare tire 280 is opened on the fixing bracket 112. The fixing bracket 112 is detachably connected to the support plate 111.

[0046] The spare tire reinforcement bracket 120 includes a support plate 121 and a reinforcement plate 122.

[0047] The tray 111 of the quick-change spare tire mounting structure of the embodiment of the present application can not only be used to cover the trunk storage slot 260 to separate the trunk of the vehicle into two independent spaces, but also a fixing bracket 112 for mounting the second spare tire 280 is provided on the top of the tray 111, and the fixing bracket 112 is detachably connected to the tray 111.

[0048] When the vehicle model requires a second spare tire 280, a fixing bracket 112 for mounting the spare tire can be added to the support plate 111 to meet the user's dual spare tire requirements. When the vehicle model does not require a second spare tire 280, the fixing bracket 112 can be removed from the support plate 111. The spare tire reinforcement bracket 120 located at the bottom of the support plate 111 uses a support plate 121 and a reinforcement plate 122 to enhance the structural rigidity of the spare tire mounting bracket 110, ensuring that the spare tire mounting structure 100 meets the durability strength requirements for spare tire fixing and the requirements of relevant collision safety regulations.

[0049] Furthermore, the quick-change spare tire mounting structure 100 of the embodiment of the present application is located in the vehicle's trunk area and concealed beneath the trunk cover 130, eliminating the need for trunk space.

When the lower support plate 111 needs to be removed, the bolts between the support plate 111 and the front connecting plate 113 and the rear connecting plate 114 are first removed, and then the buckle of the spare tire reinforcement bracket 120 is moved to the left or right relative to the socket of the rear floor cross beam 240 to a set stroke. After that, they can be unlocked and separated from each other, avoiding the difficulty of disassembly using bolts and other connection methods.

[0068] How it works

[0069] An embodiment of the present application provides a quick-change spare tire mounting structure and a vehicle. Since the quick-change spare tire mounting structure 100 of the present application is provided with a spare tire mounting bracket 110, the spare tire mounting bracket 110 includes a support plate 111 covering the trunk storage slot 260 and a fixed bracket 112 located on the top of the support plate 111, and a mounting hole for mounting the spare tire is opened on the fixed bracket 112, and the fixed bracket 112 is detachably connected to the support plate 111; a spare tire reinforcement bracket 120, the spare tire reinforcement bracket 120 includes a support plate 121 and a reinforcement plate 122, the support plate 121 and the reinforcement plate 122 are both located at the bottom of the support plate 111 and are both connected to the support plate 111, and the reinforcement plate 122 is connected to the support plate 121 at one end away from the support plate 111.

[0070] Therefore, the tray 111 of the quick-change spare tire mounting structure of the present application can not only be used to cover the trunk storage slot 260 and separate the trunk of the vehicle into two independent spaces, but also a fixing bracket 112 for mounting the spare tire is provided on the top of the tray 111. The fixing bracket 112 is detachably connected to the tray 111. When the vehicle type needs to add a spare tire, a fixing bracket 112 for mounting the spare tire can be added to the tray 111 to meet the user's need for dual spare tires. When the vehicle type does not need to add a spare tire, the fixing bracket 112 can be removed from the tray 111. The spare tire reinforcement bracket 120 located at the bottom of the tray 111 uses a support plate 121 and a reinforcing plate 122 to enhance the structural rigidity of the spare tire mounting bracket 110, so that the spare tire mounting structure 100 meets the durability strength requirements for spare tire fixation and the requirements of relevant collision safety regulations.

[0071] In addition, the quick-change spare tire mounting structure 100 of the present application is arranged in the trunk area of ​​the vehicle and is hidden under the trunk cover 130, not occupying the trunk space. This structure is fixed to the vehicle body cross beam 230, the rear floor under-cross beam 240, and the vehicle body rear panel 250 in a detachable manner. This structure fully utilizes the gap space between the functional modules under the trunk cover 130 and does not affect the layout of existing functional modules, pipelines, and wiring harnesses. This spare tire mounting structure 100 can be quickly installed and removed from the vehicle body rear structure 200. For vehicles equipped with a spare tire, only the spare tire mounting structure 100 needs to be installed. For vehicles without a spare tire, the fixing bracket 112 of this spare tire mounting structure 100 can be removed without affecting other functions and configurations of the vehicle.
