[0002] As motorcycles become more popular as a convenient and flexible means of transportation, users' demands for their carrying capacity are becoming increasingly diverse. Traditional motorcycle designs are often only equipped with fixed storage spaces, which makes it difficult to meet users' different demands for carrying capacity in different scenarios.

[0003] The patent with announcement number CN220842785U discloses a motorcycle trunk with adjustable space. When adjusting the size of the motorcycle trunk space, the rotating knob drives the rotating rod and the bevel gears on both sides to rotate simultaneously, thereby driving the driven wheel and the threaded rod to rotate synchronously, and finally drives the circular box body to slide up and down on the inner wall of the lower box body, thereby adjusting the motorcycle trunk space. It is suitable for different models of motorcycles and reduces the production cost of the trunk.

[0004] Although the above scheme adjusts the space of the motorcycle trunk by adjusting the height between the circular box body and the lower box body, the above scheme is adjusted before the trunk is installed on the motorcycle. The size of the trunk after installation is fixed. When the total volume of the items exceeds the carrying capacity of the trunk, the items cannot be put into the trunk. The items need to be fixed on the outside of the trunk. The motorcycle vibrates during driving, and the vibration may cause the items to fall from the trunk. Summary of the invention

[0005] In view of the above problems, a motorcycle with a multifunctional load-bearing structure is provided. By arranging a main box body, a box cover, an expansion component, an expansion drive structure, a main cover plate and a drive component, the load-bearing capacity of the motorcycle is expanded, so that the load-bearing structure can carry more items with a larger total volume in a short time, and prevent some items fixed on the outside of the tail box from falling.

[0006] To solve the problems of the prior art, the present invention provides a motorcycle with a multifunctional bearing structure, comprising a connecting bracket and a bearing structure arranged on a tail bracket, wherein the bearing structure comprises a main box body, a box cover, two expansion components, an expansion drive structure, a main cover plate and a drive component;

[0011] The main cover plate is arranged on the upper end of the expansion drive structure, and slots are provided at both ends of the main cover plate, and the two expansion boxes are respectively located in the two slots;

[0012] The driving assembly is arranged on one side of the expansion driving structure, and the driving assembly is transmission-connected to the expansion driving structure.

[0013] Preferably, a first window is provided at the upper end of the expansion box, and the expansion component further comprises an opening and closing component, and the opening and closing component is arranged at the first window.

[0014] Preferably, the expansion component further includes two auxiliary components, and the two auxiliary components are respectively arranged on both sides of the upper half of the expansion box.

[0015] Preferably, a second window is provided on the wall surface of the expansion box facing the interior of the main box body.

[0016] Preferably, the expansion drive structure includes two mounting seats, two telescopic components and four guide components.

[0017] Preferably, the driving assembly comprises a rotating shaft, a main gear and two driven gears.

[0018] Preferably, the drive assembly further comprises a telescopic shaft.

[0019] Preferably, the driving assembly further comprises a locking assembly, and the locking assembly is arranged at one end of the rotating shaft (361).

[0020] Preferably, the bearing structure further comprises two auxiliary cover plates, the two auxiliary cover plates are respectively arranged on two notches of the main cover plate, and the auxiliary cover plates have the same shape as the notches.

[0021] Preferably, the bearing structure further comprises a storage assembly, and the storage assembly is arranged at the inner top of the box cover.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention is provided with a main box body, a box cover, an expansion component, an expansion drive structure, a main cover plate and a drive component. Under normal conditions, the two expansion components are stored in the main box body, which maintains the closed and regular appearance of the load-bearing structure and reduces the air resistance during driving. The sealing plate is tightly attached to the outer wall of the main box body, effectively preventing dust or rain from entering the interior of the main box body and protecting the internal items from the external environment. The main cover plate covers the top of the expansion drive structure, which not only ensures that the items are placed stably, but also avoids direct contact between the items and the expansion drive structure, reducing the risk of damage to the items. When it is necessary to carry large-volume items, the expansion drive structure is driven by the drive component to move the expansion component to both sides along the bottom of the main box body and fully extend it, thereby maximizing the expansion of the internal space of the main box body, so that the motorcycle can flexibly adjust the load-bearing capacity according to actual needs, thereby realizing the expansion of the motorcycle's load-bearing capacity, enabling the load-bearing structure to carry more items with a larger total volume in a short time, and avoiding the falling of some items fixed on the outside of the tail box.

[0024] 2. The present invention is provided with an opening and closing component. The first window opened at the upper end of the expansion box allows the items placed in the expansion box to be taken out directly without opening the entire box lid, which greatly improves the convenience and efficiency of taking out items. The opening and closing component arranged at the first window forms a stable overall structure through the coordinated use of the first closing plate, the second closing plate and the locking plate, thereby ensuring the sealing of the expansion box during driving and effectively blocking the interference of the external environment.

DETAILED DESCRIPTION

[0038] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] Reference Figures 1 to 12 As shown: a motorcycle with a multifunctional bearing structure, comprising a connecting bracket 2 and a bearing structure 3 arranged on a tail bracket 1, the bearing structure 3 comprising a main box body 31, a box cover 32, two expansion components 33, an expansion drive structure 34, a main cover plate 35 and a drive component 36; the lower end of the main box body 31 is connected to the connecting bracket 2; the box cover 32 is arranged at the upper end of the main box body 31, and one side of the box cover 32 is connected to the main box body 31 through a hinge; the two expansion components 33 are respectively arranged at the two ends inside the main box body 31, and the expansion drive structure 34 is arranged at the two ends inside the main box body 31. The expansion assembly 33 includes an expansion box 331, and a sealing plate 332 is arranged on one side of the expansion box 331; the expansion drive structure 34 is arranged at the bottom inside the main box body 31, and the expansion drive structure 34 is connected to the lower ends of the two expansion boxes 331; the main cover plate 35 is covered on the upper end of the expansion drive structure 34, and slots are opened at both ends of the main cover plate 35, and the two expansion boxes 331 are respectively located in the two slots; the drive assembly 36 is arranged on one side of the expansion drive structure 34, and the drive assembly 36 is connected to the expansion drive structure 34 in transmission.

[0040] First, under normal conditions, the two expansion components 33 are stored in the internal space of the main box body 31. At this time, the expansion box 331 is completely located in the main box body 31, and the sealing plate 332 is tightly attached to the outer wall of the main box body 31 to prevent dust or rainwater from entering the main box body 31. The main box body 31 and the box cover 32 are connected by hinges to form a closed and regular appearance. This state is conducive to reducing the air resistance of the motorcycle during driving. When the total volume of the items to be carried is small, if the space of the main box body 31 meets the carrying requirements, there is no need to adjust the bearing structure 3, and the original shape of the bearing structure 3 is maintained to ensure the stability of the driving resistance. When encountering items with a larger total volume and the original space of the main box body 31 is not enough to accommodate them, the drive component 36 can be operated. The drive component 36 It is transmission connected to the expansion drive structure 34. Under the drive of the drive component 36, the expansion drive structure 34 enables the two expansion components 33 to move to both sides along the bottom of the main box body 31 until the expansion box 331 is completely extended out of the main box body 31. At this time, the internal space of the main box body 31 is maximized. At the same time, the two expansion boxes 331 serve as supplementary space to jointly meet the carrying requirements of large-volume items. To ensure that the items are placed stably and avoid direct contact with the expansion drive structure 34, the main cover plate 35 covers the top of the expansion drive structure 34. The carrying capacity of the main box body 31 is adjusted through the expansion drive structure 34 and the two expansion components 33, thereby realizing the expansion of the motorcycle's carrying capacity, so that the carrying structure 3 can carry more items in a short time.

[0041] Reference Figure 4 and Figure 5 As shown: a first window 3311 is provided at the upper end of the expansion box 331, and the expansion component 33 also includes an opening and closing component 333, which is arranged at the first window 3311, and includes a first closing plate 3331, a second closing plate 3332, a locking plate 3333 and a limiting card plate 3334; one end of the first closing plate 3331 is connected to the expansion box 331 by a hinge; one end of the second closing plate 3332 is connected to the expansion box 331 by a hinge, and the second closing plate 3332 is placed on the first closing plate 3331; the locking plate 3333 is arranged on the lower surface of the second closing plate 3332, and one end of the locking plate 3333 is axially connected to the second closing plate 3332; the limiting card plate 3334 is arranged on the lower surface of the first closing plate 3331, and a limiting card groove is formed between the limiting card plate 3334 and the first closing plate 3331.

[0042] The first window 3311 is provided at the upper end of the expansion box 331, and the items placed in the expansion box 331 can be taken out directly without opening the box cover 32, which improves the convenience of taking out the items. In addition, an opening and closing component 333 is provided at the first window 3311. After placing the items in the expansion box 331, the first closing plate 3331 is first rotated to be flush with the upper end surface of the expansion box 331, and then the second closing plate 3332 is rotated to the same position, and one end of the second closing plate 3332 is overlapped on the upper end of the first closing plate 3331, and then the locking plate 3333 is rotated to lock the locking plate 33 One end of 33 is embedded in the limiting card plate 3334 to form a locked state. At this time, the locking plate 3333 is stuck between the first closing plate 3331 and the limiting card plate 3334, ensuring that the first closing plate 3331 and the second closing plate 3332 are tightly combined to form a stable whole, ensuring that the first closing plate 3331 and the second closing plate 3332 will not separate even if the motorcycle encounters vibration during driving, and the first window 3311 is kept closed, thereby ensuring the sealing of the expansion box 331 during driving and effectively blocking interference from the external environment.

[0043] Reference Figure 5 and Figure 6 As shown: the expansion component 33 also includes two auxiliary components 334, and the two auxiliary components 334 are respectively arranged on both sides of the upper half of the expansion box 331, and the auxiliary components 334 include an L-shaped plate 3341, a support plate 3342, a first guide column 3343 and a first spring 3344; one end of the L-shaped plate 3341 is connected to the side wall of the expansion box 331; the support plate 3342 is parallel to the inner wall of the expansion box 331; the first guide column 3343 is slidably connected to the L-shaped plate 3341, and one end of the first guide column 3343 is connected to the support plate 3342; the first spring 3344 is sleeved on the first guide column 3343, and the two ends of the first spring 3344 are respectively abutted against the L-shaped plate 3341 and the support plate 3342.

[0044] Since the bottom of the expansion box 331 is connected to the expansion drive structure 34, the lower end of the expansion box 331 can be subjected to the force of the expansion drive structure 34, and the lower end of the expansion box 331 can better suppress the vibration of the motorcycle during driving, while the upper end of the expansion box 331 is not supported by any support, so the expansion box 331 will swing continuously, resulting in an increase in the force on the connection between the expansion box 331 and the expansion drive structure 34. By arranging an auxiliary component 334 on the upper half of the expansion box 331, the expansion box 331 is moved out of the main box body 31 through L The type plate 3341 drives the support plate 3342 to move toward the main box body 31. When the support plate 3342 abuts against the inner wall of the main box body 31, the expansion box 331 continues to drive the L-shaped plate 3341 to move. The L-shaped plate 3341 squeezes the first spring 3344, and the first spring 3344 accordingly applies a force to the expansion box 331 through the L-shaped plate 3341, so that the upper end of the expansion box 331 does not swing during the driving of the motorcycle, thereby reducing the force on the connection between the expansion box 331 and the expansion drive structure 34, and reducing the risk of the expansion box 331 falling from the expansion connection structure.

[0045] Reference Figure 5 As shown: a second window 3312 is opened on the wall of the expansion box 331 facing the inside of the main box body 31.

[0046] When the motorcycle is carrying some longer items, due to the width limitation of the main box 31, it is unable to directly accommodate items that exceed its own size range. Therefore, a second window 3312 is opened on the wall surface of the expansion box 331 facing the inside of the main box 31. First, one end of the long item to be stored is placed into one of the expansion boxes 331 from the inside of the main box 31, and the item is tilted through the second window 3312 between the expansion box 331 and the main box 31. Then, taking advantage of the space advantage of the connection between the expansion box 331 and the main box 31, the item is placed in the main box 31 along the diagonal direction. After the item enters the main box 31, the other end of the item is placed in another expansion box 331. Through the connectivity of the second window 3312, it is ensured that the entire item is placed in the storage space formed by the main box 31 and the two expansion boxes 331, thereby realizing the storage of long items and enhancing the practicality of the carrying structure 3.

[0047] Reference Figure 5 and Figure 7As shown: the expansion drive structure 34 includes two mounting seats 341, two telescopic components 342 and four guide components 343; the two mounting seats 341 are arranged parallel to each other on both sides of the inner bottom of the main box body 31; the two telescopic components 342 are arranged between the two mounting seats 341, and the two telescopic components 342 are respectively connected to the bottom of the two expansion boxes 331, the telescopic component 342 includes a bidirectional screw rod 3421, two moving blocks 3422 and two driving plates 3423, the two ends of the bidirectional screw rod 3421 are respectively connected to the two mounting seats 341, and the two moving blocks 3422 are respectively arranged on the two-way screw rod 3421 On the two threaded parts, the two driving plates 3423 correspond to the two moving blocks 3422 respectively, and the two ends of the driving plates 3423 are respectively connected to the expansion box 331 and the moving block 3422; the four guide components 343 are divided into a group of two, and the two guide components 343 in a group are respectively arranged on both sides of the expansion box 331, and the guide components 343 include a guide rod 3431 and a slider 3432, the guide rod 3431 is perpendicular to the two-way screw rod 3421, and the guide rod 3431 is connected to the inner bottom of the main box body 31, the slider 3432 is slidably set on the guide rod 3431, and the slider 3432 is connected to the expansion box 331.

[0048] When the expansion box 331 needs to be extended out of the main box body 31, the bidirectional screw rod 3421 rotates, driving the two moving blocks 3422 to approach each other, and applying a thrust toward the outside of the main box body 31 to the expansion box 331 through the two driving plates 3423. Under the action of the two thrusts, the expansion box 331 begins to move toward the outside of the main box body 31. At the same time, the movement of the expansion box 331 drives the two sliders 3432 connected thereto to slide on the guide rods 3431. The two sliders 3432 are respectively limited by their respective guide rods 3431. The manufacturing function ensures that the expansion box 331 can translate along the axial direction of the guide rod 3431. When the two-way screw rod 3421 stops rotating, the two moving blocks 3422 will also stop moving. Since there is a self-locking mechanism between the two-way screw rod 3421 and the moving blocks 3422, the vibration generated during the driving of the motorcycle will not cause the moving blocks 3422 to move along the two-way screw rod 3421, thereby ensuring that the expansion box 331 can maintain its position stability during the movement, and effectively preventing the squeezing of other items in the main box body 31.

[0049] Reference Figure 5 and Figure 8As shown: the driving assembly 36 includes a rotating shaft 361, a main gear 362 and two driven gears 363; the rotating shaft 361 is arranged between the two telescopic assemblies 342, and the middle part of the rotating shaft 361 is connected to the mounting seat 341, one end of the rotating shaft 361 extends into the interior of the main box body 31, and the other end of the rotating shaft 361 is flush with the outer wall surface of the main box body 31, and the other end of the rotating shaft 361 is provided with a transmission hole 3611; the main gear 362 is arranged at one end of the rotating shaft 361, and the main gear 362 is connected to the rotating shaft 361; the two driven gears 363 are respectively arranged on both sides of the main gear 362, the driven gear 363 is meshed with the main gear 362, and the driven gear 363 is connected to the telescopic assembly 342.

[0050] When there is a difference in the degree to which the two expansion boxes 331 extend out of the main box body 31, the motorcycle may face the problem of uneven distribution of air resistance during driving, which may lead to imbalance on both sides of the motorcycle. Therefore, it is necessary to control the degree to which the two expansion boxes 331 extend out of the main box body 31. The user rotates the rotating shaft 361 clockwise. As the rotating shaft 361 rotates, the main gear 362 rotates, thereby driving the two driven gears 363 to rotate synchronously. The two driven gears 363 respectively drive the two bidirectional screw rods 3421 to rotate synchronously. As the two bidirectional screw rods 3421 rotate, the two expansion boxes 331 extend out of the main box body 31 at the same speed. On the contrary, when the user rotates the rotating shaft 361 counterclockwise, the main gear 362 will rotate counterclockwise, driving the two expansion boxes 331 to retract into the main box body 31 at the same speed, thereby achieving synchronous extension and retraction of the two expansion boxes 331, thereby ensuring that the air resistance encountered by the two ends of the main box body 31 during driving is consistent, thereby maintaining the balance of the motorcycle.

[0051] Reference Figure 4 and Fig. 9 As shown: the driving assembly 36 also includes a telescopic shaft 364, which is slidably arranged in the transmission hole 3611, and a limiting column 3641 is arranged at one end of the telescopic shaft 364, and a limiting sliding groove 3612 cooperating with the limiting column 3641 is opened on the rotating shaft 361.

[0052] If one end of the rotating shaft 361 extends out of the main housing 31, although the rotating shaft 361 can be directly rotated, the outer surface of the main housing 31 is uneven, which affects the appearance of the main housing 31. Therefore, a transmission hole 3611 is opened in the rotating shaft 361, and a telescopic shaft 364 is arranged in the transmission hole 3611. When the rotating shaft 361 needs to be rotated, the user first pulls the telescopic shaft 364 out of the transmission hole 3611 of the rotating shaft 361, and the limiting column 3641 at one end of the telescopic shaft 364 slides along the limiting groove 3612 opened on the rotating shaft 361, thereby preventing the telescopic shaft 364 from completely extending out of the rotating shaft 36 1. Subsequently, the user can drive the rotating shaft 361 to rotate by rotating the telescopic shaft 364. Due to the close fit between the telescopic shaft 364 and the transmission hole 3611, the rotation action will be effectively transmitted to the rotating shaft 361, thereby driving the rotation of the main gear 362 and the two driven gears 363, thereby realizing the synchronous telescopic extension of the expansion box 331. After adjusting the positions of the two expansion boxes 331, it is only necessary to reinsert the telescopic shaft 364 into the transmission hole 3611 of the rotating shaft 361, thereby avoiding the unevenness of the outer surface of the main box body 31 and maintaining the neatness and beauty of the appearance of the main box body 31.

[0053] Reference Figure 4 , Figure 5 and Fig.10 As shown: the driving assembly 36 also includes a locking assembly 365, which is arranged at one end of the rotating shaft 361, and the locking assembly 365 includes a first fixed seat 3651, a locking shaft 3652, a locking screw 3653 and a push plate 3654; the first fixed seat 3651 is connected to the main box body 31, a through hole is opened in the middle of the first fixed seat 3651, and a threaded hole connected to the through hole is opened at the upper end of the first fixed seat 3651; the locking shaft 3652 is slidably set in the through hole, and a locking docking hole 3613 cooperating with the locking shaft 3652 is opened at one end of the rotating shaft 361; the locking screw 3653 is set in the threaded hole; the push plate 3654 is set at the end of the locking shaft 3652.

[0054] Since the rotating shaft 361 is not locked, other personnel can pull out the telescopic shaft 364 from the rotating shaft 361, and then drive the rotating shaft 361 to rotate, so that the two expansion boxes 331 extending out of the main box body 31 are retracted into the main box body 31. By setting the locking component 365, in the initial state, one end of the locking shaft 3652 is inserted into the locking docking hole 3613 of the rotating shaft 361, which effectively locks the rotating shaft 361 to prevent the rotating shaft 361 from rotating without authorization. When the position of the two expansion boxes 331 needs to be adjusted, the locking screw 3653 needs to be rotated first to separate the locking screw 3653 from the locking shaft 3652 to release the fixation of the locking shaft 3652, and then the push plate 3654 needs to be pushed. The push plate 3654 drives the locking shaft 3652 to slide along the through hole until one end of the locking shaft 3652 is completely moved out of the locking docking hole 3613. At this time, the rotating shaft 361 is able to rotate freely around its own axis. After completing the adjustment of the positions of the two expansion boxes 331, the push plate 3654 is pushed in the reverse direction so that the push plate 3654 drives the locking shaft 3652 to be reinserted into the locking docking hole 3613, and then the locking screw 3653 is rotated in the reverse direction so that one end of the locking screw 3653 is tightly in contact with the locking shaft 3652, and the locking shaft 3652 is fixed again, thereby preventing unauthorized rotation operations and preventing the expansion box 331 from being retracted into the main box body 31 without permission.

[0055] Reference Fig.11 As shown, the bearing structure 3 further includes two auxiliary cover plates 37 , which are respectively arranged on two notches of the main cover plate 35 , and the auxiliary cover plates 37 have the same shape as the notches.

[0056] When the two expansion boxes 331 are both in the main box body 31, the two expansion boxes 331 are respectively in the two slots. When the two expansion boxes 331 extend out of the main box body 31, the expansion drive structure 34 below the two slots is in an exposed state, and the items placed in the main box body 31 will fall to the lower end of the main cover plate 35. By setting two auxiliary covers 37, after the two expansion boxes 331 are fully extended out of the main box body 31, the two auxiliary covers 37 are respectively covered on the two slots, and the main cover plate 35 and the two auxiliary covers 37 form a continuous and flat plane, which completely covers the exposed expansion drive structure 34, thereby preventing items from falling to the lower end of the main cover plate 35, ensuring the safety of the items in the main box body 31.

[0057] Reference Figure 2 , Figure 4 and Fig.12As shown: the bearing structure 3 also includes a storage component 38, which is arranged on the inner top of the box cover 32, and the storage component 38 includes a first L-shaped card plate 381 and a tightening component 382; a card slot is formed between the first L-shaped card plate 381 and the box cover 32; the tightening component 382 is arranged on one side of the first L-shaped card plate 381, and the tightening component 382 includes a second fixing seat 3821, a second L-shaped card plate 3822, a second guide column 3823 and a second spring 3824, and the second fixing seat 3821 is arranged parallel to the first L-shaped card plate On one side of 381, the second L-shaped card plate 3822 is arranged between the first L-shaped card plate 381 and the second fixed seat 3821, and the second L-shaped card plate 3822 is parallel to the first L-shaped card plate 381, the second guide column 3823 is slidably connected to the second fixed seat 3821, and one end of the second guide column 3823 is connected to the second L-shaped card plate 3822, the second spring 3824 is sleeved on the second guide column 3823, and the two ends of the second spring 3824 are respectively abutted against the second fixed seat 3821 and the second L-shaped card plate 3822.

[0058] When the two expansion boxes 331 are both in the main box body 31 and the two slots are occupied, the auxiliary cover 37 needs to be temporarily stored in the top of the box cover 32. First, one side of the auxiliary cover 37 is inserted into the slot formed by the first L-shaped card plate 381, and then the second L-shaped card plate 3822 is pushed toward the second fixing seat 3821. During this process, the second spring 3824 is compressed, causing the distance between the second L-shaped card plate 3822 and the first L-shaped card plate 381 to increase until the distance is greater than the width of the auxiliary cover 37. At this time, the auxiliary cover 37 is completely pressed onto the inner top of the lower box cover 32, and the force on the second L-shaped card plate 3822 is removed. Under the elastic force of the second spring 3824, the second L-shaped card plate 3822 is quickly reset and clamps the other side of the auxiliary cover 37, so that the two sides of the auxiliary cover 37 are subjected to opposite forces, thereby achieving stable fixation and effectively preventing the auxiliary cover 37 from shaking during the driving of the motorcycle.
