[0034] DETAILED DESCRIPTION
[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may also be a centered element. When an element is considered to be "set on" another element, it may be directly set on the other element or there may also be a centered element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.
[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present application. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "or / and" used herein includes any and all combinations of one or more related listed items.
[0038] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.
[0039] In this embodiment, the first direction X is the X-axis direction of the vehicle coordinate system, the second direction Z is the Z-axis direction of the vehicle coordinate system, and the third direction Y is the Y-axis direction of the vehicle coordinate system. In other embodiments, the first direction X, the second direction Z and the third direction Y can also be adjusted according to actual needs.
[0040] See also Figures 1 to 3 The present embodiment provides a spare tire pool 100, which includes a main body 10 and a reinforcing coating layer 20. The main body 10 includes a bottom wall 11 and a side wall 12, the side wall 12 is bent and connected to the bottom wall 11, and the side wall 12 and the bottom wall 11 form a storage slot 13, and the storage slot 13 has a horizontal opening 14 opened along a first direction X and a vertical opening 15 opened along a second direction Z, and the first direction X intersects with the second direction Z. The reinforcing coating layer 20 is coated on the surface of the main body 10, and the reinforcing coating layer 20 is used to strengthen the strength of the main body 10, and the reinforcing coating layer 20 at least covers the junction of the bottom wall 11 and the side wall 12.
[0041] The reinforced coating layer 20 can reinforce the strength of the main body 10. The reinforced coating layer 20 covering the junction of the bottom wall 11 and the side wall 12 can reliably reinforce the connection between the bottom wall 11 and the side wall 12. When the depth of the storage slot 13 increases and the spare tire well 100 carries heavier items, the reinforced coating layer 20 can ensure the connection reliability at the junction of the bottom wall 11 and the side wall 12, and greatly reduce the possibility of fracture between the bottom wall 11 and the side wall 12. In this way, the volume and carrying capacity of the spare tire well 100 can be improved, and the reliability of the use of the spare tire well 100 can be ensured.
[0042] At the same time, the storage slot 13 of the main body 10 is provided with a horizontal opening 14 and a vertical opening 15. Compared with the spare tire well 100 structure having only a vertical opening 15, the spare tire well 100 of this embodiment has a higher processing depth. By cooperating with the reinforced coating layer 20, the depth of the storage slot 13 can be further increased, thereby improving the utilization rate of the space under the rear floor of the vehicle 200.
[0043] In this embodiment, the material of the reinforcing coating layer 20 is an elastic protective material, which has a high tensile strength, which can be higher than 20MPa, or higher than 24MPa, and a large elongation at break, which can be higher than 250%, for example, the elongation at break can be as high as 300%. The material of the reinforcing coating layer 20 can be specifically set to polyurethane elastomer, epoxy resin, silicone, isocyanate prepolymer, and the material of part of the reinforcing coating layer 20 can also be set to A glue and B glue, wherein A glue can be made of aliphatic isocyanate, cyclic isocyanate or modified isocyanate polymer, and B glue can be made of polyol material. A glue and B glue can be mixed at room temperature and then coated on the surface of the main body 10, thereby improving the rigidity of the main body 10.
[0044] The above materials can also disperse stress. When the main body 10 is loaded with items, the bearing force is dispersed to different positions of the main body 10 through its own elasticity to improve the fatigue resistance of the main body 10. In addition, the reinforced coating layer 20 formed by mixing A glue and B glue also has high cross-linking degree, high toughness and high strength, which can further improve the protective effect. At the same time, the reinforced coating layer 20 formed by mixing A glue and B glue also has excellent adhesion ability, which can greatly extend the retention time of the reinforced coating layer 20 on the main body 10.
[0045] The specific material and specific proportion of the reinforcing coating layer 20 can be determined according to existing related materials, and will not be described in detail in this embodiment.
[0046] At the same time, compared with the existing thermal spraying method of coating metal or ceramic coating on the surface of the main body 10, the reinforcing coating layer 20 of this embodiment is also easy to process. Of course, in other embodiments of the present application, the reinforcing coating layer 20 can also be set as a metal or ceramic coating.
[0047] In this embodiment, see Figure 1 The width of the vertical opening 15 along the first direction X is L1, the width of the vertical opening 15 along the third direction Y is L2, the third direction Y intersects the second direction Z and the first direction X, the distance between the vertical opening 15 and the bottom wall 11 along the second direction Z is D, 0.5≤L1 / D≤4, 2≤L2 / D≤4.
[0048] L1 / D can be set to any one of 0.5, 1, 1.5, 2, 2.5, 3, 3.5, and 4, and L2 / D can be set to any one of 2, 2.5, 3, 3.5, and 4.
[0049] The depth of the main body 10 of this embodiment (i.e., the distance D between the vertical opening 15 and the bottom wall 11 along the second direction Z) is greater than the depth of the known spare tire pool 100 without a reinforcing coating layer 20, so that the lower limit values of L1 / D and L2 / D are both reduced.
[0050] In this embodiment, see Figure 3 , the wall thickness of the main body 10 is H1, the thickness of the reinforcing coating layer 20 is H2, and 0.5≤H2 / H1≤1. Within this range, both the economic cost and the reinforcing effect of the reinforcing coating layer 20 on the main body 10 can be taken into account. If H2 / H1 is too high, the coating cost of the reinforcing coating layer 20 is too high, and the additional buffering effect is not obvious, and the marginal effect is more obvious. If H2 / H1 is too low, the buffering and dispersion effect of the reinforcing coating layer 20 on the collision force is insufficient, making it difficult for the reinforcing coating layer 20 to improve the rigidity and impact resistance of the main body 10.
[0051] Optionally, H2 / H1 can be set to any one of 0.5, 0.6, 0.7, 0.8, 0.9, and 1.
[0052] In this embodiment, see Figure 3 The main body 10 also includes an arc surface segment 16, and the side wall 12 and the bottom wall 11 are transitionally connected by the arc surface segment 16. The angle between the side wall 12 and the vertical surface M perpendicular to the bottom wall 11 is α, α≥10°, and the reinforced coating layer 20 at least covers the arc surface segment 16.
[0053] The arc surface segment 16 makes the junction between the bottom wall 11 and the side wall 12 smoother. When the spare tire well 100 carries objects, the stress borne by the arc surface segment 16 is more uniform. Combined with the coating of the arc surface segment 16 by the reinforced coating layer 20, the fatigue resistance of the spare tire well 100 can be further improved.
[0054] In addition, in order to ensure the overall strength reliability of the spare tire well 100, the lower limit of the angle α between the side wall of some known spare tire wells and the vertical plane perpendicular to the bottom wall is generally 20°. In this embodiment, since the reinforcing coating layer 20 is coated on the arc surface segment 16, the lower limit of the angle between the side wall 12 and the vertical plane M perpendicular to the bottom wall 11 can be as low as 10°. In this way, the space between the vertical plane M perpendicular to the bottom wall 11 and the side wall 12 is made smaller, and the width or length of the bottom wall 11 can be increased, thereby further improving the volume utilization rate of the spare tire well 100.
[0055] In this embodiment, the reinforcing coating layer 20 is coated on the outer surface of the main body 10, that is, the reinforcing coating layer 20 is completely coated on the outer surface of the side wall 12, the outer surface of the bottom wall 11 and the outer surface of the arc surface segment 16, thereby further improving the overall strength of the spare tire pool 100. During the production process of the spare tire pool 100, the ultra-deep stamping material can be first formed into the shape of the main body 10 by stamping, and then the reinforcing coating layer 20 is coated on the outer surface of the main body 10. In this way, during the operation of the vehicle 200, if an object applies a local impact load to the main body 10, the local impact load can be dispersed to other areas of the main body 10 through the reinforcing coating layer 20, thereby avoiding the problem of stress concentration, so that the main body 10 can bear the impact load more evenly, and reduce the possibility of bulging or damage to the main body 10. In addition, the reinforcing coating layer 20 on the outer surface of the main body 10 is not easily damaged by stored items, thereby extending the life of the reinforcing coating layer 20.
[0056] In other embodiments, the reinforcing coating layer 20 may also be coated on the inner surface of the main body 10 .
[0057] Optionally, the main body 10 in this embodiment can be made of ultra-deep stamping material, which can be made of steel plate material with high elongation, and its tensile strength is generally lower than 160MPa. After being coated with the reinforcing coating layer 20, the tensile strength of the spare tire pool 100 can be guaranteed to be as high as 200MPa or more, ensuring the strength and rigidity of the spare tire pool 100. Specifically, the ultra-deep stamping material can be DC06 steel. In other embodiments, the ultra-deep stamping material can be set to other materials, which are not specifically limited in this embodiment.
[0058] In this embodiment, see Figure 1 The side wall 12 is provided with a first reinforcing structure 171 formed inwardly or outwardly convexly. The bottom wall 11 is provided with a second reinforcing structure 172 formed inwardly or outwardly convexly.
[0059] Both the first reinforcement structure 171 and the second reinforcement structure 172 can improve the strength of the main body 10, and can also guide and disperse the force applied to the spare tire well 100 by objects, thereby improving the load-bearing capacity of the spare tire well 100. At the same time, the first reinforcement structure 171 can also improve the adhesion effect of the reinforcement coating layer 20 on the side wall 12, and the second reinforcement structure 172 can improve the adhesion effect of the reinforcement coating layer 20 on the bottom wall 11, thereby ensuring that the reinforcement coating layer 20 remains on the main body 10 for a long time, and avoiding the problem of delamination between the reinforcement coating layer 20 and the main body 10.
[0060] In addition, the first reinforcement structure 171 can also apply a certain pulling force to the bottom wall 11 and improve the local rigidity of the side wall 12 , thereby improving the load-bearing performance of the spare tire well 100 .
[0061] In this embodiment, see Figure 1A portion of the bottom wall 11 , the side wall 12 and the arc surface segment 16 that are continuous with each other is concave or convex to form a third reinforcement structure 173 .
[0062] The third reinforcement structure 173 can improve the strength of the main body 10, and can also guide and disperse the force applied to the spare tire well 100 by the objects, thereby improving the bearing capacity of the spare tire well 100. At the same time, the third reinforcement structure 173 can improve the adhesion effect of the reinforcement coating layer 20 on the bottom wall 11, thereby ensuring that the reinforcement coating layer 20 remains on the main body 10 for a long time.
[0063] In this embodiment, see Figure 1 The side wall 12 and a continuous portion of the arc surface segment 16 are concave or convex together to form a fourth reinforcement structure 174, that is, the fourth reinforcement structure 174 is arranged at the side wall 12 and the connection between the side wall 12 and the arc surface segment 16, and extends to the arc surface segment 16.
[0064] The fourth reinforcement structure 174 can improve the strength of the main body 10, and can also guide and disperse the force applied by the object to the spare tire well 100, thereby improving the load-bearing capacity of the spare tire well 100. At the same time, the fourth reinforcement structure 174 can improve the adhesion effect of the reinforcement coating layer 20 on the side wall 12, thereby ensuring that the reinforcement coating layer 20 remains on the main body 10 for a long time.
[0065] In this embodiment, see Figure 4 The extension direction of the projection of the first reinforcing structure 171 on the plane where the bottom wall 11 is located, the extension direction of the projection of the third reinforcing structure 173 on the plane where the bottom wall 11 is located, and the extension direction of the projection of the fourth reinforcing structure 174 on the plane where the bottom wall 11 is located are all parallel to the first direction X, so as to guide the load exerted on the main body 10 to diffuse along the extension direction of the reinforcing coating layer 20, thereby improving the stress dispersion effect of the reinforcing coating layer 20.
[0066] In this embodiment, the second reinforcement structure 172 is roughly cross-shaped and is also connected to the third reinforcement structure 173. In this way, stress can be transmitted between the bottom wall 11 and the side wall 12 through the second reinforcement structure 172 and the third reinforcement structure 173 to improve the stress dispersion effect.
[0067] In this embodiment, see Figure 4The side wall 12 includes a first wall segment 121, a second wall segment 122 and a third wall segment 123. The first wall segment 121 and the second wall segment 122 are respectively connected to two sides of the bottom wall 11 that are oppositely arranged along the third direction Y. The third wall segment 123 is arranged on one side of the bottom wall 11 along the first direction X. The third wall segment 123 is connected to the first wall segment 121 on one side along the third direction Y, and is connected to the second wall segment 122 on the other side along the third direction Y. The first wall segment 121, the second wall segment 122 and the side of the bottom wall 11 away from the third wall segment 123 along the first direction X form a horizontal opening 14. The first wall segment 121, the second wall segment 122 and the side of the third wall segment 123 away from the bottom wall 11 along the second direction Z form a vertical opening 15.
[0068] In this embodiment, see Figure 4 The side wall 12 further includes two arc-shaped connecting walls 124, one arc-shaped connecting wall 124 is connected between the first wall segment 121 and the third wall segment 123, and the other arc-shaped connecting wall 124 is connected between the second wall segment 122 and the third wall segment 123. The two arc-shaped connecting walls 124 can improve the smoothness of the connection between the third wall segment 123 and the first wall segment 121 and / or the second wall segment 122, and facilitate the conduction of stress between the three through the reinforcing coating layer 20 at the arc-shaped connecting walls 124, further improving the stress dispersion effect.
[0069] In this embodiment, see Figure 4 The first wall segment 121 is provided with a first reinforcement structure 171, the second wall segment 122 is provided with a first reinforcement structure 171, and the third wall segment 123 is provided with two first reinforcement structures 171, parts of two third reinforcement structures 173 and parts of two fourth reinforcement structures 174, wherein the third wall segment 123 is provided with a first reinforcement structure 171, a part of a third reinforcement structure 173 and a part of a fourth reinforcement structure 174 on both symmetrical sides along the third direction Y, respectively.
[0070] In this embodiment, see Figure 2 and Figure 4 The main body 10 further includes a first flange 175, which is bent and connected to the side of the side wall 12 away from the bottom wall 11 along the second direction Z, and the first flange 175 is bent toward the outside of the storage slot 13. The first flange 175 is used to be connected to the rear floor or rear longitudinal beam of the vehicle 200 to fix the main body 10 to the vehicle 200. By bending the first flange 175 toward the outside, it is possible to avoid occupying the space of the vertical opening 15 during the connection between the main body 10 and the vehicle body 201, thereby improving the utilization rate of the vertical opening 15.
[0071] In other embodiments, the first flange 175 may also be bent toward the inner side of the storage slot 13 .
[0072] Alternatively, see Figure 4 The first flange 175 is provided with a plurality of fifth reinforcing structures 179 , and the plurality of fifth reinforcing structures 179 are formed inwardly or outwardly from a portion of the first flange 175 to improve the rigidity of the first flange 175 .
[0073] In this embodiment, see Figure 2 and Figure 4 The spare tire well 100 further includes a second flange 176, which is bent and connected to the edge of the main body 10 where the horizontal opening 14 is opened, and the second flange 176 is bent toward the inside of the storage slot 13. The second flange 176 is used to connect to a component of the vehicle 200 to close the horizontal opening 14. The component of the vehicle 200 may be a rear panel 202 or a separate panel. By bending the second flange 176 inward, the sealing of the horizontal opening 14 can be improved and the possibility of water seepage can be reduced.
[0074] In other embodiments, the second flange 176 may also be bent toward the outside of the storage slot 13 .
[0075] See also Figure 1 The spare tire pool 100 further includes a plurality of liquid leakage reinforcement structures 177, each of which is provided with a liquid leakage hole 178, wherein a portion of the side wall 12 is convex or concave to form a portion of the liquid leakage reinforcement structure 177, and a portion of the bottom wall 11 is convex or concave to form another portion of the liquid leakage reinforcement structure 177. The number and position of the liquid leakage reinforcement structure 177 can be set at different positions of the side wall 12 and the bottom wall 11 according to actual needs, and this embodiment does not specifically limit it.
[0076] See also Figure 5 This embodiment further provides a vehicle 200 , including a vehicle body 201 and the aforementioned spare tire well 100 . The spare tire well 100 is connected to the vehicle body 201 .
[0077] Since the vehicle 200 includes the spare tire pool 100 of the above embodiment, it has the beneficial effects of the spare tire pool 100 of the above embodiment, which will not be described in detail here.
[0078] In this embodiment, see Figure 5 and Figure 6 The vehicle 200 further includes a rear panel 202. The horizontal opening 14 of the spare tire pool 100 is open along the first direction X toward the rear of the vehicle body 201 and cooperates with the rear panel 202. The rear panel 202 closes the horizontal opening 14. In this way, the utilization rate of the rear panel 202 can be improved.
[0079] In other embodiments, the horizontal opening 14 of the spare tire well 100 may be closed by an additional sealing plate.
[0080] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
