It should be understood that the data used in this way can be exchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a class, and are not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0042] It should be understood that "some embodiments" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiments are included in at least one embodiment of the present application. Therefore, "in some embodiments" appearing throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0043] A wheel cover reinforcing device, a wheel cover reinforcing structure and a vehicle provided by the present application will be described in detail below by listing specific embodiments.

[0044] The wheel cover reinforcing device of the present application comprises at least two wheel cover connecting parts, and the at least two wheel cover connecting parts are adapted to be connected with different wheel cover assemblies.

[0045] Specifically, the vehicle includes four wheel cover assemblies, two of which are located at the front wheels of the vehicle, namely a left front wheel cover assembly and a right front wheel cover assembly, and the other two of which are located at the rear wheels of the vehicle, namely a left rear wheel cover assembly and a right rear wheel cover assembly. The wheel cover reinforcing device of the present application includes at least two wheel cover connecting parts. If there are two wheel cover connecting parts, the two wheel cover connecting parts can be connected to any two of the left front wheel cover assembly, the right front wheel cover assembly, the left rear wheel cover assembly and the right rear wheel cover assembly. For example, the two wheel cover connecting parts can be connected to the left front wheel cover assembly and the right front wheel cover assembly respectively, or to the left rear wheel cover assembly and the right rear wheel cover assembly respectively, thereby establishing a connection relationship between the two front wheel cover assemblies or between the two rear wheel cover assemblies. If there are three wheel cover connecting parts, the three wheel cover connecting parts can be connected to any three of the left front wheel cover assembly, the right front wheel cover assembly, the left rear wheel cover assembly and the right rear wheel cover assembly, thereby establishing a connection relationship between the front wheel cover assemblies and the rear wheel cover assemblies of the vehicle. If there are four wheel cover connecting parts, two of the four wheel cover connecting parts are connected to the left front wheel cover assembly and the right front wheel cover assembly respectively, and the other two are connected to the left rear wheel cover assembly and the right rear wheel cover assembly respectively. In the embodiment of the present application, the two wheel cover connecting parts are connected to the left rear wheel cover assembly and the right rear wheel cover assembly respectively.

[0046] In the prior art, as shown in Figure 1 The left rear wheel cover assembly 1 and the right rear wheel cover assembly 2 of the vehicle are independent of each other in structure and connection, resulting in low modal stiffness and torsional stiffness of the whole rear part of the vehicle body. The modal stiffness is mainly used to analyze the stiffness characteristics in structural dynamics, and the modal is an inherent property of the vehicle body. The modal parameters include modal frequency, modal shape and modal damping. The modal shape of the vehicle body is the vibration shape of the vehicle body at a specific frequency, and the specific frequency is the modal frequency. The modal damping is a parameter for suppressing structural vibration. The torsional stiffness of the vehicle refers to the ability of the vehicle body to resist elastic deformation when subjected to external force. It can also be understood as the ratio of the force applied to the vehicle structure to the deformation value of the structure, and is an important indicator for measuring the strength of the vehicle body. If the modal stiffness and torsional stiffness of the whole rear part of the vehicle body are not high, the left rear wheel cover assembly 1 or the right rear wheel cover assembly 2 is prone to torsional deformation when the vehicle experiences severe jolt or side impact, resulting in damage to the whole vehicle body and threatening the safety of passengers.

[0047] The two wheel cover connecting parts of the wheel cover reinforcing device are connected with the left rear wheel cover assembly and the right rear wheel cover assembly respectively, the connection relationship between the left rear wheel cover assembly 1 and the right rear wheel cover assembly 2 is established, the current situation that the left rear wheel cover assembly 1 and the right rear wheel cover assembly 2 are independent in structure is changed, the structural rigidity and the structural stability of the left rear wheel cover assembly 1 and the right rear wheel cover assembly 2 are effectively improved, the risk of torsional deformation of the left rear wheel cover assembly 1 and the right rear wheel cover assembly 2 is reduced, the degree of torsional deformation of the left rear wheel cover assembly 1 and the right rear wheel cover assembly 2 is reduced, and therefore the integrity of the vehicle body structure is maintained and the life safety of passengers is protected. It should be noted that the advantages of the two wheel cover connecting parts of the wheel cover reinforcing device being connected with the left front wheel cover assembly and the right front wheel cover assembly respectively are basically the same as the advantages of the two wheel cover connecting parts being connected with the left rear wheel cover assembly and the right rear wheel cover assembly respectively, and the embodiment of the present application will not be repeated here.

[0048] Optionally, the wheel cover reinforcing device further comprises a floor connecting part, and the floor connecting part is adapted to be connected with a floor.

[0049] Specifically, the floor connecting part is adapted to be connected with the floor, the floor is welded to a chassis, the chassis belongs to part of a vehicle body support, and the floor is provided with components required by a vehicle such as a seat and a footrest. The floor connecting part is connected with the floor, so that the wheel cover reinforcing device is connected with the wheel cover assembly and the floor at the same time, the connection reliability of the wheel cover reinforcing device is improved, the wheel cover reinforcing device can provide more reliable support for the left rear wheel cover assembly 1 and the right rear wheel cover assembly 2, and therefore the structural rigidity and the structural stability of the left rear wheel cover assembly 1 and the right rear wheel cover assembly 2 are further improved, the risk of torsional deformation of the left rear wheel cover assembly 1 and the right rear wheel cover assembly 2 is reduced, and the integrity of the vehicle body structure is maintained.

[0050] Optionally, referring to Figure 2 , the wheel cover reinforcing device further comprises a connecting beam and a support; the connecting beam is arranged between the two wheel cover connecting parts and connected with the wheel cover connecting parts respectively; and the support is arranged between the connecting beam and the floor connecting part and connected with the connecting beam and the floor connecting part respectively.

[0051] Specifically, the connecting beam 3 is arranged along the width direction of the vehicle body, and is arranged between two wheel cover connecting parts, one of which is connected with the left rear wheel cover assembly 1, and the other of which is connected with the right rear wheel cover assembly 2. The connection between the wheel cover connecting part and the left rear wheel cover assembly 1 and the right rear wheel cover assembly 2 includes but is not limited to welding, assembly connection and the like, and the specific connection manner is not limited in the embodiment. The connecting beam 3 and the two wheel cover connecting parts establish an indirect connection relationship between the left rear wheel cover assembly 1 and the right rear wheel cover assembly 2, and the left rear wheel cover assembly 1, the connecting beam 3, the right rear wheel cover assembly 2 and the floor 5 jointly form a ring-shaped frame structure at the rear of the vehicle body, effectively enhancing the modal stiffness and torsional stiffness of the whole rear of the vehicle body. When the vehicle is subjected to severe bumping or side impact, the impact force received by the left rear wheel cover assembly 1 can be transmitted to the right rear wheel cover assembly 2 through the wheel cover connecting part and the connecting beam 3, and the impact force received by the right rear wheel cover assembly 2 can also be transmitted to the left rear wheel cover assembly 1 through the wheel cover connecting part and the connecting beam 3, thereby reducing the risk of torsional deformation of the left rear wheel cover assembly 1 and the right rear wheel cover assembly 2 and reducing the degree of torsional deformation of the left rear wheel cover assembly 1 and the right rear wheel cover assembly 2, which helps to protect the integrity of the vehicle body structure.

[0052] Further, the wheel cover reinforcing device further comprises a support member 4 arranged along the height direction of the vehicle body and arranged between the connecting beam 3 and the floor connecting part. One end of the support member 4 is connected with the connecting beam 3, and the other end of the support member 4 is connected with the floor connecting part. The connection manner includes but is not limited to welding, assembly connection and the like, and the specific connection manner is not limited in the embodiment. The arrangement of the support member 4 increases the force transmission path during the side impact of the vehicle. For example, the impact force received by the left rear wheel cover assembly 1 can be transmitted to the right rear wheel cover assembly 2 through the wheel cover connecting part and the connecting beam 3, and can also be transmitted to the support member 4 below through the connecting beam 3, and then transmitted to the floor 5 through the support member 4 and the floor connecting part. Correspondingly, the impact force received by the right rear wheel cover assembly 2 can be transmitted to the left rear wheel cover assembly 1 through the wheel cover connecting part and the connecting beam 3, and can also be transmitted to the support member 4 below through the connecting beam 3, and then transmitted to the floor 5 through the support member 4 and the floor connecting part. That is, the impact force received by the left rear wheel cover assembly 1 and the right rear wheel cover assembly 2 can be dispersed to the vehicle body to achieve force buffering, thereby further enhancing the modal stiffness and torsional stiffness of the whole rear of the vehicle body, preventing the vehicle body from torsional deformation, and protecting the integrity of the vehicle body structure.

[0053] In summary, the wheel cover reinforcing device of the embodiment of the application comprises a wheel cover connecting portion, a floor connecting portion, a connecting beam 3 and a support 4, the connecting beam 3 is connected between the two wheel cover connecting portions, the support 4 is connected between the connecting beam 3 and the floor connecting portion, the connecting beam 3 is arranged to form a ring-shaped frame structure at the rear of the vehicle body, which can effectively increase the modal stiffness and torsional stiffness of the rear of the vehicle body as a whole, and reduce the risk of torsional deformation of the vehicle body, and meanwhile, the arrangement of the support 4 increases the force transmission path at the rear of the vehicle body, when the rear wheel cover assembly is subjected to a side impact force, the impact force can be transmitted not only to the rear wheel cover assembly on the other side through the wheel cover connecting portion and the connecting beam 3, but also to the floor 5 through the connecting beam 3, the support 4 and the floor connecting portion, so that the force is dispersed, thereby further improving the force absorption effect of the rear of the vehicle body, preventing the rear of the vehicle body from being torsionally deformed, and helping to protect the integrity of the vehicle body structure and the safety of passengers.

[0054] Figure 3 A connecting schematic diagram of the connecting beam 3 and the support 4 in the embodiment of the application is shown, referring to Figure 3 The support 4 is at least two, comprising a first support 41 and a second support 42; the first support 41 is obliquely connected with the connecting beam 3 and the floor connecting portion, and / or the second support 42 is obliquely connected with the connecting beam 3 and the floor connecting portion.

[0055] Specifically, the support 4 is at least two, and the number of the support 4 can be arranged according to the width of the connecting beam 3 and the stiffness requirement of the vehicle body, for some large vehicles such as SUVs, off-road vehicles, etc., the width of the connecting beam 3 is wider, and then the number of the support 4 can be increased accordingly, for some small vehicles such as small cars, mini sports cars, etc., the width of the connecting beam 3 is narrower, and then the number of the support 4 can be reduced accordingly, and the specific number of the support 4 is not limited in the embodiment. Figure 3As shown, the at least two support members 4 include a first support member 41 and a second support member 42, in a first embodiment, the first support member 41 is obliquely connected with the connecting beam 3 and the floor connecting portion respectively, the included angle between the first support member 41 and the connecting beam 3 and the floor connecting portion is an acute angle or an obtuse angle, and the included angle between the second support member 42 and the connecting beam 3 and the floor connecting portion can be a right angle; in a second embodiment, the second support member 42 is obliquely connected with the connecting beam 3 and the floor connecting portion respectively, the included angle between the second support member 42 and the connecting beam 3 and the floor connecting portion is an acute angle or an obtuse angle, and the included angle between the first support member 41 and the connecting beam 3 and the floor connecting portion can be a right angle; in the above two embodiments, the first support member 41 and the second support member 42 form a structure similar to a right trapezoid between the connecting beam 3 and the floor connecting portion; in a third embodiment, the first support member 41 and the second support member 42 are obliquely connected with the connecting beam 3 and the floor connecting portion respectively, and the included angles between the first support member 41 and the second support member 42 and the connecting beam 3 and the floor connecting portion are all acute angles or obtuse angles; in the third embodiment, the first support member 41 and the second support member 42 can be parallel to each other, or can form a positive "eight" structure or an inverted "eight" structure, and when the first support member 41 and the second support member 42 transmit the impact force from the connecting beam 3 in this structure, two directional components can be formed, one of which is along the width direction of the vehicle body, and the other is along the height direction of the vehicle body, thereby more facilitating the transmission and buffering of the force, avoiding the stress concentration phenomenon, protecting the reliability of the connecting portion of the connecting beam 3 and the support member 4, and further improving the buffering and energy absorption effect of the rear part of the vehicle body.

[0056] Optionally, referring to Figure 3 , the inner side of the first support member 41 and the inner side of the second support member 42 form a first included angle with the connecting beam 3, and the inner side of the first support member 41 and the inner side of the second support member 42 form a second included angle with the floor connecting portion; the first included angle is an acute angle, and the second included angle is an obtuse angle.

[0057] Specifically, the inner side of the first support member 41 is the side of the first support member 41 facing the second support member 42, the inner side of the second support member 42 is the side of the second support member 42 facing the first support member 41, the inner side of the first support member 41 and the inner side of the second support member 42 form a first included angle with the connecting beam 3, and the first included angle is as shown in Figure 3 ɑ , the inner side of the first support member 41 and the inner side of the second support member 42 form a second included angle with the floor connecting portion, and the second included angle is as shown in Figure 3 , wherein the first included angle ɑ ​In this case, the first support member 41 and the second support member 42 form a structure similar to an inverted triangle or an inverted trapezoid, so that the distance between the first support member 41 and the second support member 42 and the connecting portion of the connecting beam 3 is greater than the distance between the first support member 41 and the second support member 42 and the connecting portion of the floor. The distance between the first support member 41 and the second support member 42 and the connecting portion of the connecting beam 3 is shown as S1 in FIG. 1, and the distance between the first support member 41 and the second support member 42 and the connecting portion of the floor is shown as S2 in FIG. 1, S1>S2, forming a structure similar to an inverted triangle or an inverted trapezoid, which has high structural stability and helps to improve the structural rigidity of the rear portion of the vehicle body. At the same time, S1>S2 can unify the directions of the two force transmission paths and avoid stress concentration, thereby ensuring the connection reliability of the connecting beam 3 and the support member 4. Figure 3 Figure 3

[0058] For example, in the case of a side impact of the left rear wheelhouse assembly 1, one force transmission path is that the left rear wheelhouse assembly 1 transmits the impact force to the right rear wheelhouse assembly through the wheelhouse connecting portion and the connecting beam 3, and the other force transmission path is that the left rear wheelhouse assembly 1 transmits the impact force to the floor 5 through the connecting beam 3, the support member 4, and the floor connecting portion. If S1>S2, the force transmission direction on the connecting beam 3 is from left to right along the vehicle body width direction, and the component force of the force transmission direction on the support member 4 is also from left to right along the vehicle body width direction. Obviously, the component force direction of the support member 4 is consistent with the force transmission direction of the connecting beam 3, and the force directions are consistent during force transmission, so stress concentration is not likely to occur at the connecting portion of the connecting beam 3 and the support member 4, thereby helping to ensure the connection reliability of the connecting beam 3 and the support member 4 and the force transmission capacity of the connecting beam 3 and the support member 4. Conversely, if S1<S2, the force transmission direction on the connecting beam 3 is from left to right along the vehicle body width direction, but the component force of the force transmission direction on the support member 4 becomes from right to left along the vehicle body width direction. Obviously, the component force direction of the support member 4 is inconsistent with the force transmission direction of the connecting beam 3, and stress concentration is likely to occur at the connecting portion of the connecting beam 3 and the support member 4, which causes deformation, loosening, and other phenomena of the connecting portion of the connecting beam 3 and the support member 4, thereby affecting the stability of the overall structure. Therefore, S1>S2 is set in this embodiment, which can effectively ensure the connection reliability of the connecting beam 3 and the support member 4, and then ensure the force transmission capacity of the connecting beam 3 and the support member 4.

[0059] Optionally, referring to FIG. 1, Figure 3 the first support member 41 and the second support member 42 are symmetrically arranged along a direction perpendicular to the connecting beam 3.

[0060] ​​Specifically, the direction perpendicular to the connecting beam 3 is the height direction of the vehicle body, the first support 41 and the second support 42 are symmetrically arranged along the height direction of the vehicle body, and in some preferred embodiments, the height direction can pass through the center of the connecting beam 3, and the first support 41 and the second support 42 are symmetrically arranged along the direction, so that the connection with the connecting beam 3 is more uniform, which helps to realize uniform force transmission of the left and right rear wheel cover assemblies 1 and 2, and further helps to improve the stability of the rear structure of the vehicle body.

[0061] Figure 4 A structural schematic diagram of a connecting beam 3 in an embodiment of the application is shown, referring to Figure 4 , the connecting beam 3 is internally provided with a plurality of reinforcing ribs 30, and the plurality of reinforcing ribs 30 separate the interior of the connecting beam 3 to form a plurality of hollow cavities 31.

[0062] Specifically, the connecting beam 3 is a hollow structure, and the interior of the connecting beam 3 is provided with a plurality of reinforcing ribs 30, and the plurality of reinforcing ribs 30 separate the interior of the connecting beam 3 to form a plurality of hollow cavities 31, which helps to reduce the overall weight of the connecting beam 3, realize lightweight design of the rear wheel cover reinforcing structure, and ensure the structural rigidity and strength of the connecting beam 3, avoiding excessive distortion and deformation of the connecting beam 3, thereby ensuring the force transmission effect of the connecting beam 3 on the left and right rear wheel cover assemblies 1 and 2. In some preferred embodiments, a plurality of weight reduction holes can be formed on the connecting beam 3, which are through holes, to further reduce the overall weight of the connecting beam 3. Of course, the position and number of the weight reduction holes should be set in combination with the rigidity and strength requirements of the connecting beam 3.

[0063] Optionally, referring to Figure 4 , the plurality of reinforcing ribs 30 are symmetrically distributed along the center line of the connecting beam 3, and the center line is a line connecting the midpoints of the two sides of the connecting beam 3 along the extension direction thereof.

[0064] Specifically, the plurality of reinforcing ribs 30 are symmetrically distributed along the center line of the connecting beam 3, and the center line is a line connecting the midpoints of the two sides of the connecting beam 3 along the extension direction thereof, the connecting beam 3 extends along the width direction of the vehicle body, and the formed center line is shown as L1 in Figure 4 , that is, the plurality of reinforcing ribs 30 are symmetrically distributed along L1, so that the force transmission of the connecting beam 3 on the left and right rear wheel cover assemblies 1 and 2 is more uniform, the force transmission effect is better, and local deformation is not easy to occur during force transmission, and the overall structural stability is good.

[0065] Optionally, referring to Figure 4 , the connecting beam 3 is provided with a first mounting hole 32 at the end thereof along the extension direction thereof, and the first mounting hole 32 is used for penetrating a fastener to detachably connect the connecting beam 3 with the wheel cover connecting portion.

[0066] Specifically, along the extension direction of the connecting beam 3, the first mounting hole 32 is arranged at the position close to the end of the connecting beam 3, the first mounting hole 32 is a through hole, and a fastener such as a bolt, a screw or a rivet is arranged in the first mounting hole 32, so that the connecting beam 3 and the wheel cover connecting part are detachably connected together through the fastener. In order to strengthen the connection effect of the fastener, the first mounting hole 32 can be a threaded hole, and structure glue or the like can be added to the periphery of the first mounting hole 32 after the fastener is arranged in the first mounting hole 32, so as to avoid loosening or slipping of the fastener.
