[0010] Among them, each connecting bracket, corresponding auxiliary frame extending obliquely upward, and corresponding side wing of the rear wheel cover plate form a triangular support structure.

[0011] Compared with the prior art, the scheme shown in the embodiments of the present application has the following advantages: two groups of connecting brackets are arranged to extend obliquely to the rear of the diagonal, to form a support main body penetrating through the front and rear ends of the side box, and to form a stable triangular support structure with the corresponding side sub-frame and rear wheel cover plate, so that the triangular support structure forms the basis of the support of the side box, and the lightness and stability of the basis support are ensured; two groups of fixing blocks are used instead of the traditional rod or column structure, so that the overall installation structure is lightened, and a connection form that takes into account both the upper and lower parts is formed between the connecting brackets, thereby further enhancing the connection and support strength; further, a reinforcing rod is arranged at the tail part to further support the two side connecting brackets at the tail part, so that the reinforcing rod is in correspondence with the front ends of the connecting brackets, and a cage frame structure is formed between the connecting brackets, the fixing blocks and the reinforcing rod, so that the rigidity of the installation structure is ensured while the mass of the installation structure is reduced.

[0012] In a possible implementation manner, the connecting bracket comprises:

[0013] a transverse support part connected to the bottom of the corresponding side box and fixed at the front end of the sub-frame;

[0014] a longitudinal support part connected at one end to the rear end of the transverse support part and extending upward at the other end and fixed to the rear wheel cover plate.

[0016] In terms of the upper and lower structure, the fixing block is arranged above the transverse support part, so that the connecting bracket can be stably supported at the bottom of the side box, and the fixing block can effectively support the upper part of the side box; in terms of the front and rear support structure, the connecting bracket extends from the front side to the rear, the transverse support part and the longitudinal support part penetrate through the front and rear of the side box support, and the reinforcing rod is used as auxiliary support to increase the support stability of the tail part.

[0017] In some embodiments, a plurality of connecting plates are arranged on the transverse support part at intervals, the plurality of connecting plates extend horizontally and are supported at the bottom of the corresponding side box, and are fixed to the corresponding side box.

[0018] By arranging a plurality of connecting plates, on the one hand, the connecting bracket can be connected to the side box through the connecting plates, and on the other hand, the connecting plates can be used for stable lifting at the bottom of the side box to achieve strong support of the bottom of the side box.

[0019] Exemplarily, the longitudinal support part extends from the gap between the rear wheel cover plate and the side box to the inner side of the rear wheel cover plate and is fixed to the inner side wall of the rear wheel cover plate.

[0020] By extending the longitudinal support part to the inner side of the rear wheel cover plate, the connection strength between the side box and the rear wheel side plate is enhanced; specifically, the side box can be pulled to the side of the rear wheel cover plate by the longitudinal support part, so as to improve the tightness of the connection between the two.

[0021] Exemplarily, the reinforcing rod is connected to the middle part of the two longitudinal support parts.

[0022] By arranging the reinforcing rod in the middle part of the longitudinal support part, the force acting on the longitudinal support part is relatively uniform, so as to effectively ensure the connection strength of the reinforcing rod and improve the rigidity of the mounting structure.

[0023] Exemplarily, the two ends of the reinforcing rod are provided with two plate-shaped fixing parts, and the reinforcing rod is connected to the connecting bracket through the fixing parts.

[0024] In a possible implementation, the connecting bracket is connected to the rear wheel cover plate through a Z-shaped connecting piece, one side of the Z-shaped connecting piece is abutted and fixed to the rear end side wall of the connecting bracket, and the other side is abutted and fixed to the side wing of the rear wheel cover plate.

[0025] By arranging the Z-shaped connecting piece, the contact area between the side box and the rear wheel cover plate can be increased, so that the fixing of the connecting bracket is more stable and reliable, so as to prevent displacement or falling of the side box during driving.

[0026] In some embodiments, one side of the Z-shaped connecting piece is arc-shaped, and the other side is planar; the arc-shaped side of the Z-shaped connecting piece is abutted to the rear end side wall of the connecting bracket, and the planar side of the Z-shaped connecting piece is abutted to the side wing of the rear wheel cover plate.

[0027] By arranging the arc-shaped side of the Z-shaped connecting piece to be abutted to the rear end side wall of the connecting bracket, the contact area between the Z-shaped connecting piece and the connecting bracket can be further increased, so as to further enhance the connection strength therebetween.

[0028] In a possible implementation, the fixing block is in a Z-shaped structure, one side of the Z-shaped structure is abutted to and fixed to the corresponding side box, and the other side is abutted to and fixed to the side wing of the rear wheel cover plate.

[0029] By arranging the cross section of the fixing block in a Z-shaped structure, the corresponding side contact area between the fixing block and the side box and the rear wheel cover plate can be increased, and a support main beam is formed in the longitudinal direction, so as to improve the connection strength and support stability of the fixing block.

[0030] In some embodiments, the number of the fixing blocks in each group is two, and the two fixing blocks are arranged in front of and behind each other; wherein the fixing block on the rear side is close to the rear end of the connecting support and is clamped and fixed on the inner and outer sides of the rear wheel cover plate with the rear end of the connecting support.

[0031] By reasonably setting the number of the fixing blocks, the overall installation structure can be reduced in weight while the support strength and the connection strength are ensured, which is beneficial to the lightweight processing of the motorcycle.

[0039] In order to make the technical problems, technical solutions and beneficial effects of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model.

[0040] It should be noted that when an element is referred to as being "disposed on" another element, it can be directly on the other element or indirectly on the other element. It should be understood that the terms "upper", "lower", "front", "back", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship of the motorcycle body shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.

[0041] In addition, for the convenience of description, "mounting structure" is used in the present application to refer to the "mounting structure of the motorcycle side box" provided by the utility model.

[0042] In the description of the utility model, the meaning of "a plurality of" is two or more than two, unless otherwise explicitly specified. The terms "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include one or more of the features.

[0043] It should be noted that the motorcycle body is provided with two side boxes, and the two side boxes are specifically left side box 8 and right side box 9, for the convenience of description, side box is used in the present application to describe the above-mentioned left side box 8 and right side box 9; In addition, a rear wheel cover plate 7 is arranged above the rear wheel of the motorcycle body, and the mounting structure of the motorcycle side box provided in the present application is used to be mounted between the two side boxes of the motorcycle and the rear wheel cover plate 7, and the rear wheel cover plate 7 includes a connecting portion and two side wings; The connecting portion is arranged above the rear wheel of the motorcycle, and the two side wings extend downward from the two sides of the connecting portion, and the outer side of each side wing corresponds to a side box.

[0044] In the conventional structure, the mounting structure of the motorcycle side box is usually arranged between the side box and the side wing of the rear wheel cover plate 7, and is formed by a bottom connecting frame and an upper connecting frame, and a support frame connected between the bottom connecting frame and the upper connecting frame. Although this structure can guarantee the connection strength, it is redundant in materials and heavy in quality, which is not convenient for the implementation of lightweight motorcycle body.

[0045] It should be noted that the drawings attached in the present application Figure 1The dashed line area of the rear wheel cover plate 7 indicates the installation position of the rear wheel cover plate 7 in the actual situation, and the structure of the rear wheel cover plate 7 is not completely drawn due to the influence of the installation of the rear wheel cover plate 7 on the display of the components in the drawing. Moreover, the structure of the rear wheel cover plate 7 is not the focus of the application, and therefore, it is not described in detail.

[0046] Please refer to Figures 1 to 3 , the installation structure of the motorcycle side box and the motorcycle provided by the utility model will be described. The installation structure of the motorcycle side box comprises two groups of fixing blocks 1, two connecting brackets 2 and a reinforcing rod 3. The two groups of fixing blocks 1 correspond to the two side boxes respectively. One side of the fixing block 1 is fixed with the corresponding side box, and the other side is used for being fixed on the side wing of the rear wheel cover plate 7. The two connecting brackets 2 are connected with the two side boxes respectively. One end of the connecting bracket 2 is arranged below the fixing block 1 and is used for being connected with the auxiliary frame 6 of the motorcycle body. The other end of the connecting bracket 2 extends obliquely upward to the rear side and is fixed on the side wing of the rear wheel cover plate 7. The reinforcing rod 3 is arranged at the tail of the rear wheel cover plate 7 and is fixed with the two connecting brackets 2 at the two ends respectively. Among them, a triangular support structure is formed between each connecting bracket 2, the corresponding auxiliary frame 6 extending obliquely upward and the side wing of the corresponding rear wheel cover plate 7.

[0047] It should be noted that the connecting bracket 2 and the fixing block 1 provided in the application are both fixed on the corresponding side wing of the rear wheel cover plate 7. Moreover, the integrated structure design of the connecting bracket 2 provided in the application can greatly simplify the support structure. The fixing block 1 forms a longitudinal support main beam by separate support, and is supplemented by the reinforcing rod 3 to strengthen, so as to ensure the support strength and reduce the overall quality at the same time. Moreover, the triangular support structure formed between the connecting bracket 2, the corresponding auxiliary frame 6 and the side wing of the rear wheel cover plate 7 can further improve the rigid support strength.

[0048] It should be noted that the structure of the auxiliary frame 6 of the motorcycle body is inclined upward and extends rearward from the front end of the rear wheel cover plate 7. Since the connecting bracket 2 also extends obliquely rearward and upward, a triangular support frame can be formed between the auxiliary frame 6, the connecting bracket 2 and the side wing of the rear wheel cover plate 7. Moreover, the side wing of the rear wheel cover plate 7 can be filled and supported in the formed triangular support frame, so that the auxiliary frame 6, the connecting bracket 2 and the side wing of the rear wheel cover plate 7 form a triangular support structure.

[0049] Specifically, the triangular support structure comprises a triangular support frame and an internal filled panel support. Among them, the auxiliary frame 6 and the connecting bracket 2 form two support edges of the triangular support frame, and the side wing of the rear wheel cover plate 7 forms the panel support and the other support edge in the triangle.

[0050] The cage type frame structure formed between the connecting support 2, the fixing block 1 and the reinforcing rod 3 can effectively disperse the force applied by the side box on the rear wheel cover plate 7 and the like, enhances the stability and the bump resistance of the whole mounting structure, and makes the side box not easy to shake and loosen during driving, thereby improving the safety and the comfort of riding.

[0051] In addition, it should be understood that the structure can be adaptively adjusted in size according to different types and sizes of motorcycles, has good universality and installation convenience, and can meet the needs of different users.

[0052] Compared with the prior art, the mounting structure of the motorcycle side box provided by the utility model forms the support main body penetrating through the front and rear ends of the side box by arranging two groups of connecting supports 2 extending obliquely rearward, and makes the connecting supports 2 form stable triangular support structures with the corresponding side auxiliary frames 6 and the rear wheel cover plates 7, so that the triangular support structures form the basis of supporting the side box and ensure the lightness and stability of the basis support; and the two groups of fixing blocks 1 are adopted to replace the traditional rod type or column type structure, which not only reduces the overall weight of the mounting structure, but also forms a connecting form taking into account the upper and lower connections between the connecting supports 2, thereby further enhancing the connection and support strength; further, the reinforcing rods 3 arranged at the tail portions of the connecting supports 2 can further support the connecting supports 2 at the tail portions, so that the reinforcing rods 3 correspond to the front ends of the connecting supports 2, and then the cage type frame structure is formed between the connecting supports 2, the fixing blocks 1 and the reinforcing rods 3, which can reduce the weight of the mounting structure while ensuring the rigid support strength and the connection stability of the mounting structure.

[0053] The cage type frame structure takes into account the synchronous combination of the front and rear corresponding connection structures and the upper and lower support structures of the side box, can comprehensively ensure the mounting firmness of the side box, reduces the safety hazards caused by the shaking or structural deformation of the side box, and improves the safety and the comfort of riding.

[0054] Please refer to Figure 1 In a possible embodiment, the connecting support 2 comprises a transverse support part 21 and a longitudinal support part 22; the transverse support part 21 is connected to the corresponding side box bottom and is fixed at the front end on the auxiliary frame 6; one end of the longitudinal support part 22 is connected to the rear end of the transverse support part 21, and the other end extends upward and is fixed on the rear wheel cover plate 7.

[0055] Specifically, the connecting bracket 2 is arranged between the corresponding side case and the rear wheel cover plate 7; the front end of the transverse support part 21 of the connecting bracket 2 is connected with the auxiliary frame 6 of the motorcycle body and the corresponding side case; the other end of the connecting bracket 2 extends horizontally and rearward and is bent upward to form the longitudinal support part 22, and the transverse support part 21 and the longitudinal support part 22 form a horizontally extending rearward upward inclined extending structure. At this time, the horizontally extending transverse support part 21 forms the triangular support structure between the auxiliary frame 6 and the side wing of the rear wheel cover plate 7.

[0056] It should be understood that the transverse support part 21 and the longitudinal support part 22 presented in the present application are relative, rather than absolute transverse and longitudinal directions; alternatively, the transverse support part 21 is a support beam structure extending horizontally; or the transverse support part 21 has an inclination angle of not more than about 10° with the horizontal plane, at this time, although the transverse support part 21 has an inclination angle, it is still called a horizontally extending transverse support part 21 relative to the longitudinal support part 22.

[0057] By arranging the connecting bracket 2 as the transverse support part 21 and the longitudinal support part 22, the transverse support part 21 can be conveniently supported at the bottom of the side case to effectively support the bottom of the side case; the transverse support part 21 realizes front and rear extension support, and the longitudinal support part 22 is used to realize upward and downward extension support in the longitudinal direction, so that the connecting bracket 2 forms the main body of the support frame structure.

[0058] In the present application, the connecting bracket 2 is divided into the transverse support part 21 and the longitudinal support part 22, which can optimize the force transmission path, and further, one end of the longitudinal support part 22 is connected with the rear end of the transverse support part 21, and the other end extends upward and is fixed on the rear wheel cover plate 7, which can form an internal triangular support structure again between the transverse support part 21, the longitudinal support part 22 and the rear wheel cover plate 7, and can better resist lateral force and vertical force; the longitudinal support part 22 and the transverse support part 21 together ensure the stability of the side case and enhance the stability of the side case installation.

[0059] In terms of the up-down structure, the fixing block 1 is arranged above one end of the connecting bracket 2, the connecting bracket 2 can be stably supported at the bottom of the side case, and the fixing block 1 can effectively support the upper part of the side case; in terms of the front and rear support structure, the connecting bracket 2 extends from the front side to the rear and penetrates the front and rear of the side case support, and the reinforcing rod 3 serves as auxiliary support, which increases the support stability of the tail part.

[0060] In another understanding, the triangular support structure formed between the connecting bracket 2, the upwardly inclined sub-frame 6 and the side wing of the rear wheel cover plate 7 in the present application can be understood as follows: the transverse support part 21, the longitudinal support part 22 and the upwardly inclined sub-frame 6 of the connecting bracket 2 form three edges of a triangular support frame, and the side wing of the rear wheel cover plate 7 is a filling plate inside the triangular frame. At this time, the connecting bracket 2, the sub-frame 6 and the side wing of the rear wheel cover plate 7 still form a complete triangular support structure.

[0061] Alternatively, as another specific embodiment of the connecting bracket 2 described above, one end of the connecting bracket 2 can be fixed on the motorcycle sub-frame 6 and connected and fixed with the side box through bolts, and the other end directly extends upwardly and rearwardly to form an overall inclined support structure. At this time, the inclination angle of the overall inclined connecting bracket 2 is smaller than the inclination angle of the sub-frame 6, and the connecting bracket 2 can still form a triangular support structure with the sub-frame 6 and the rear wheel cover plate 7.

[0062] In this embodiment, the multiple sets of connecting lug plates arranged on the transverse support part 21 are arranged vertically. At this time, the connecting bracket 2 still connects the side box and the rear wheel cover plate 7 through the connecting lug plates.

[0063] Please refer to Figure 1 In some embodiments, multiple connecting plates 4 are arranged on the transverse support part 21. The multiple connecting plates 4 horizontally extend and are supported on and fixed with the corresponding side box.

[0064] Through the arrangement of the multiple connecting plates 4 on the transverse support part 21, the connecting plates 4 can provide more uniform support for the side box, avoid damage caused by excessive local stress, and improve the service life of the side box. At the same time, the rear wheel cover plate 7 and the side box can be fixed tightly, reducing vibration and noise during driving and improving the riding quality.

[0065] Preferably, two connecting plates 4 are arranged, which are arranged at the front and rear of the side box and are close to the front and rear ends of the side box fixing part, respectively. On the one hand, the two sets of connecting plates 4 can effectively support the front and rear ends of the side box, and on the other hand, the overall quality of the mounting structure can be effectively controlled, which is beneficial to the lightweight design of the motorcycle.

[0066] Through the arrangement of multiple connecting plates 4, on the one hand, the connecting bracket 2 can be connected with the side box through the connecting plates 4, and on the other hand, the connecting plates 4 can be supported to stably lift the bottom of the side box, thereby achieving strong support for the bottom of the side box. Therefore, the multiple connecting plates 4 are arranged on the transverse support part 21 and support and fix the side box, which increases the contact area and connection strength between the side box and the mounting structure, and makes the side box more firmly mounted.

[0067] Further, a support ring is arranged on the lateral support part 21, the outer side wall of the support ring is fixed with the outer side wall of the connecting support 2, the axial direction of the support ring is parallel with the axial direction of the rear wheel, so as to further realize the forceful support of the side box by means of the support shaft. Specifically, a corresponding support shaft can be arranged between the bottom of the side box and the support ring, so as to improve the support strength of the side box.

[0068] Preferably, the support ring is arranged between the two connecting plates 4, so as to balance the support force of the connecting support 2 at the front and rear ends, and improve the stability of the fixed support of the side box.

[0069] Please refer to Figure 1 , for example, the longitudinal support part 22 extends from the gap between the rear wheel cover plate 7 and the side box to the inner side of the rear wheel cover plate 7, and is fixed with the inner side wall of the rear wheel cover plate 7.

[0070] The longitudinal support part 22 extends upward and inward to the inner side of the rear wheel cover plate 7, which enhances the stability of the side box mounting structure in the longitudinal direction, prevents the side box from shaking forward and backward, especially when driving at high speed or encountering bumpy road conditions, which can better fix the position of the side box and ensure the safety of riding.

[0071] It should be noted that when the longitudinal support part 22 extends from the gap between the rear wheel cover plate 7 and the side box to the outer side of the rear wheel cover plate 7, the fixing point of the longitudinal support part 22 is arranged on the outer side of the rear wheel cover plate 7. On the one hand, a fixing gap is needed between the side box and the side wing of the rear wheel cover plate 7, so that the distance between the side box and the rear wheel cover plate 7 is obvious. On the other hand, when the fixing block 1 is installed first, the gap between the side wing of the rear wheel cover plate 7 and the side box is fixed, so it is not convenient to install the longitudinal support part 22 between the side wing of the rear wheel cover plate 7 at this time. Therefore, in the present application, the longitudinal support part 22 extends from the gap between the rear wheel cover plate 7 and the side box to the inner side of the rear wheel cover plate 7, which facilitates installation and improves installation efficiency.

[0072] By extending the longitudinal support part 22 to the inner side of the rear wheel cover plate 7, the connection strength between the side box and the rear wheel side plate is enhanced. Specifically, the side box can be pulled tightly to one side of the rear wheel cover plate 7 by the longitudinal support part 22, so as to improve the tightness of the connection.

[0073] Please refer to Figure 1 , for example, the reinforcing rod 3 is connected in the middle of the two longitudinal support parts 22.

[0074] The reinforcing rod 3 is connected in the middle of the bending part of the two connecting supports 2, which can enhance the connection strength between the two connecting supports 2 and improve the rigidity of the whole mounting structure. When the side box is subjected to external force, the reinforcing rod 3 can effectively transfer and disperse the force, prevent the connecting support 2 from deforming or being damaged, and prolong the service life of the mounting structure.

[0075] Therefore, by arranging the reinforcing rod 3 in the middle of the longitudinal support part 22, the force on the longitudinal support part 22 is relatively uniform, which effectively ensures the connection strength of the reinforcing rod 3 and improves the rigidity of the mounting structure.

[0076] Optionally, a plurality of reinforcing rods 3 are arranged, and the plurality of reinforcing rods 3 are arranged in an upper and lower interval; preferably, the reinforcing rod 3 is arranged in one group or two groups, which is used to control the number of reinforcing rods 3, so as to ensure the lightweight control of the motorcycle body. The plurality of reinforcing rods 3 are arranged in an upper and lower interval, which further enhances the overall strength and stability of the mounting structure, and the support of the side box is more uniform, which can better cope with the stress changes under various complex road conditions.

[0077] Specifically, two reinforcing rods 3 are arranged in parallel between the connecting supports 2 of the two side boxes, so that the two reinforcing rods 3 and the main beam support formed by the connecting supports 2 and the fixed block 1 form a closed truss structure, which can make the transverse rigidity increase by 2-3 times of the traditional single-arm support.

[0078] Illustratively, the two ends of the reinforcing rod 3 are provided with two plate-shaped fixing parts, and the reinforcing rod 3 is connected with the connecting support 2 through the fixing parts.

[0079] Specifically, the reinforcing rod 3 includes two fixing parts at the ends and a support part arranged between the two fixing parts; optionally, the fixing part and the support part are an integral structure; or the two fixing parts are fixed on the middle support part by welding. Further, the support part of the reinforcing rod 3 is in an arc shape protruding backward, so as to adapt to the stress condition of the motorcycle body through mechanical optimization.

[0080] Optionally, a connecting column is arranged in the middle of the longitudinal support part 22 of each connecting support 2, one end of the connecting column is welded and fixed on the outer peripheral wall of the connecting support 2, the other end extends backward and is provided with a threaded hole, and the fixing part of the reinforcing rod 3 is rotatably fixed with the threaded hole on the connecting column through a high-strength screw.

[0081] Please refer to Figure 1 In some possible embodiments, the connecting support 2 is connected with the rear wheel cover plate 7 through a Z-shaped connecting piece 5, one side of the Z-shaped connecting piece 5 is abutted and fixed on the rear end side wall of the connecting support 2, and the other side is abutted and fixed on the side wing of the rear wheel cover plate 7.

[0082] Specifically, the Z-shaped connecting piece 5 is fixed to one end of the rear end side wall of the connecting bracket 2 by welding; and the Z-shaped connecting piece 5 is fixed to one side of the side wing of the rear wheel cover plate 7 by high-strength bolt and nut connection or screw connection.

[0083] By arranging the Z-shaped connecting piece 5, the contact area between the side box and the rear wheel cover plate 7 can be increased, and the fixing of the connecting bracket 2 is more stable and reliable, so as to prevent displacement or falling of the side box during driving.

[0084] Please refer to Figure 1 In some embodiments, one side of the Z-shaped connecting piece 5 is arc-shaped, and the other side is planar; the arc-shaped side of the Z-shaped connecting piece 5 abuts against the rear end side wall of the connecting bracket 2, and the planar side of the Z-shaped connecting piece 5 abuts against the side wing of the rear wheel cover plate 7.

[0085] Specifically, if the side wing of the rear wheel cover plate 7 is arc-shaped, then the side of the Z-shaped connecting piece 5 abutting against the rear wheel cover plate 7 can also be provided with an arc-shaped structure matching the same, and the connecting side of the Z-shaped connecting piece 5 can be adapted in shape according to actual needs to ensure the connection strength.

[0086] By arranging the side of the Z-shaped connecting piece 5 abutting against the rear end side wall of the connecting bracket 2 to be arc-shaped, the contact area between the Z-shaped connecting piece 5 and the connecting bracket 2 can be further increased, and thus the connection strength therebetween can be enhanced. By arranging the side of the Z-shaped connecting piece 5 abutting against the rear wheel cover plate 7 to be planar, the Z-shaped connecting piece 5 can be conveniently fixed to the side wing of the rear wheel cover plate 7.

[0087] Please refer to Figure 1 In some possible embodiments, the fixing block 1 is in a Z-shaped structure, one side of which abuts against and is fixed to the corresponding side box, and the other side abuts against and is fixed to the side wing of the rear wheel cover plate 7.

[0088] The fixing block 1 in the Z-shaped structure abuts against and is fixed to the side box on one side, and abuts against and is fixed to the rear wheel cover plate 7 on the other side, which increases the contact area between the fixing block 1 and the side box and the rear wheel cover plate 7, and the fixing is more stable, which can effectively prevent displacement or falling of the side box during driving.

[0089] Specifically, by arranging the cross section of the fixing block 1 in a Z-shaped structure, the corresponding side contact area between the fixing block 1 and the side box and the rear wheel cover plate 7 can be increased, and the middle part of the two connecting sides of the Z-shaped structure forms a support main beam in the longitudinal direction, thereby improving the connection strength and support stability of the fixing block 1.

[0090] Please refer to Figure 1In some embodiments, the number of fixed blocks 1 in each group is two, and the two fixed blocks 1 are arranged in front and back; wherein the fixed block 1 located at the rear side is close to the rear end of the connecting bracket 2 and is clamped and fixed on the inner and outer sides of the rear wheel cover plate 7.

[0091] Each group of fixed blocks 1 is provided with two and arranged in front and back, further improving the fixing stability of the side box, dispersing the fixing force, and avoiding structural deformation or damage caused by single-point fixing.

[0092] The two fixed blocks 1 arranged in front and back increase the stability of the side box installation, and compared with a single fixed block 1, can better resist forces from different directions, such as lateral impact force and longitudinal vibration, etc., so that the side box can remain stable under various road conditions. In this application, by reasonably setting the number of fixed blocks 1, the overall installation structure quality can be reduced while ensuring the support strength and connection strength, which is beneficial to the lightweight processing of the motorcycle.

[0093] It should be understood that the fixed block 1 located at the rear side is close to the rear end of the connecting bracket 2 and is clamped and fixed on the inner and outer sides of the rear wheel cover plate 7, which can form a double-point fixing structure on the rear wheel cover plate 7. This double-point fixing method enhances the overall stability of the side box mounting structure, avoids loosening caused by vibration of the rear wheel cover plate 7, and improves the safety and reliability of the side box.

[0094] In addition, the inner and outer distribution of the double-point fixing structure can help to realize the reinforced connection between the connecting bracket 2, the fixed block 1 and the rear wheel cover plate 7, increase the connection tightness, and avoid the influence of the vibration of the rear wheel cover plate 7 on the connection strength of the connecting bracket 2 and the fixed block 1.

[0095] Further, in order to realize lightweight integrated design, all components including the connecting bracket 2, the fixed block 1, the reinforcing rod 3 and the Z-shaped connecting piece 5 are made of aviation aluminum alloy. In this application, redundant materials are removed through topology optimization, realizing a weight reduction of 35% compared with traditional steel structures, while maintaining a static bearing capacity of not less than 50kg. In this application, the cage type frame structure is reasonably arranged to balance the lightweight and rigidity, and the aluminum alloy material and the cage type frame structure are cooperated to optimize the weight and strength, so as to meet the off-road riding working condition requirements.

[0096] It should be understood that the two groups of fixed blocks 1 form a longitudinal bearing main beam through the Z-shaped support structure, each connecting bracket 2 and the corresponding side leaning upward extending auxiliary frame 6, and the side wing between the corresponding side rear wheel cover plate 7 form a triangular support structure to form a torsion unit; the two connecting brackets 2 and the rear side reinforcing rod 3 form a truss type reinforcing system, thereby forming a closed truss structure with the above longitudinal bearing main beam, improving the stability and connection strength of the overall support.

[0097] In addition, the application further provides a motorcycle comprising the mounting structure of the motorcycle side case.

[0098] The motorcycle has all the beneficial effects of the mounting structure of the motorcycle side case, and can promote the light weight of the motorcycle while ensuring the rigid support strength of the side case, thereby improving the adaptability of the motorcycle to the bumpy road.

[0099] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
