Description

Technical Field

[0001] The invention relates to the technical field of packaging boxes, and in particular to a motorcycle frame packaging box and a packaging method thereof. Background Art

[0002] The current packaging method for export CKD (CKD: completely packaged goods) of motorcycle frames is to wrap the motorcycle frame with plastic film or EPE (EPE: polyethylene foam) sheet, put it directly into the packaging box or into a padded packaging box, cover it with the top cover, and then pack it for shipment.

[0003] Due to the characteristics of the frame structure: the structure is complex and difficult to stack, not only does it lead to high packaging and transportation costs, but also because the motorcycle frame is not restricted in its freedom of movement in the packaging box, and its freedom of swinging is not restricted, during the loading, transportation and unloading stacking process, the frame will collide with the packaging box under the action of external forces, causing damage and deformation of the frame product; the frame will also jump and shake in the packaging box, and it is easy to collide with the packaging box wall, resulting in bumps, scratches, deformation and other adverse conditions. The motorcycle frame is an important component with a complex structure, high product value, and many auxiliary welding parts. If there is a bad condition due to logistics, the cost of compensation is very high. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a motorcycle frame packaging box and a packaging method thereof to solve the problem that the motorcycle frame is not fixed during transportation.

[0005] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a motorcycle frame packaging box and a packaging method thereof, the motorcycle frame packaging box comprising an outer packaging box and an inner packaging box installed in the outer packaging box, the top and bottom of the inner packaging box are both open, and a accommodating cavity for installing the motorcycle frame is formed on the inner side of the inner packaging box, and a clamping component for clamping the inner packaging box and the motorcycle frame in a vertical direction is provided in the outer packaging box and at a position between the top wall of the outer packaging box and the inner packaging box. When the inner packaging box is packaged in the outer packaging box, the clamping component and the outer packaging box limit the movement of the inner packaging box and the motorcycle frame, and the accommodating cavity is used to install the motorcycle frame to avoid the motorcycle frame shaking relative to the inner packaging box and the outer packaging box during transportation, thereby ensuring the integrity and quality of the motorcycle frame.

[0006] A packaging method for packaging a motorcycle frame using a motorcycle frame packaging box includes the following installation steps:

[0007] S100, placing a motorcycle frame in an outer packaging box, and allowing the outer packaging box to initially limit the motorcycle frame in a horizontal direction;

[0008] S200, aligning the receiving cavity of the inner packaging box with the motorcycle frame, and passing the inner packaging box through the motorcycle frame and then placing it in the outer packaging box, so that the motorcycle frame is received and confined in the receiving cavity;

[0009] S300, putting the outer packaging box on the motorcycle frame and the outer periphery of the inner packaging box, and pressing the inner packaging box and the motorcycle frame into the outer packaging box in the vertical direction through the top wall of the outer packaging box and a pressing component below the top wall.

[0010] By adopting the above method, the inner packaging box, the pressing component and the outer packaging box are matched to limit the motorcycle frame in the horizontal and vertical directions to prevent the motorcycle frame from being displaced and changed relative to the outer packaging box to reduce the protectiveness of the motorcycle frame.

[0011] A clamping structure for clamping the bottom of the front end of the motorcycle frame is provided on the bottom wall of the outer packaging box corresponding to the front end of the motorcycle frame, and a cushion block for supporting the rear end of the motorcycle frame is provided at a position on the bottom wall of the outer packaging box corresponding to the rear end of the motorcycle frame; the step S100 includes the following sub-steps:

[0012] S110, clamping the bottom of the front end of the motorcycle frame in the clamping structure;

[0013] S120, supporting the rear end of the motorcycle frame on the cushion block.

[0014] By adopting the above method, the motorcycle frame can be limited in advance, and the clamping structure can limit the horizontal movement of the motorcycle frame and limit the installation position of the inner packaging box, so that the entire installation process is neat and orderly.

[0015] The clamping structure includes a fixing block arranged on the bottom wall of the outer packaging box, and a first clamping groove is formed on the fixing block to be clamped with the bottom end of the front end of the motorcycle frame. In step S110, the engine suspension plate assembly at the bottom of the front end of the motorcycle frame 1 and the left and right support pipes at the rear end of the motorcycle frame are facing downward, and the frame riser at the top of the front end of the motorcycle frame is facing upward, and the end of the engine suspension plate assembly at the bottom of the front end of the motorcycle frame is clamped in the first clamping groove and abutted against the base; in step S120, the two lifting support ears at the rear end of the motorcycle frame are supported on the pad so that the two lifting support ears are unfolded on the top of the pad.

[0016] By adopting the above method, the installation position of the motorcycle frame is determined by the first slot of the fixing block and the movement of the motorcycle frame in a partial horizontal direction is restricted, so that the motorcycle frame can be accurately located in the planned installation area and the installation can be carried out in an orderly manner.

[0017] The inner packaging box is provided in a plurality of forms and placed adjacent to each other, and when placed, the adjacent inner packaging boxes are oriented in opposite directions, the fixed block and the cushion block are provided corresponding to the inner packaging box so as to correspond to the inner packaging box one by one, a first limiting slot for limiting the vertical upward movement of the rear end of the motorcycle frame is provided at a position on the bottom side of the inner packaging box corresponding to the rear end of the motorcycle frame, a second limiting slot for limiting the vertical upward movement of the front end of the motorcycle is provided at a position on the bottom side of the inner packaging box corresponding to the top of the front end of the motorcycle frame, and a third supporting foot and a fourth supporting foot are formed on two lifting support ears corresponding to the rear end of the motorcycle frame at positions on both sides of the first limiting slot on the bottom side of the inner packaging box, respectively passing through the lifting support ears, a fifth supporting foot is extended downwardly from the bottom side of the inner packaging box corresponding to the position between the fixed block and the cushion block and supported on the bottom wall of the outer packaging box, and the S200 step includes the following sub-steps:

[0018] S210, make the accommodating cavity of the inner packaging box be located directly above the motorcycle frame, align the first limiting slot with the front end of the motorcycle frame, align the second limiting slot with the rear end of the motorcycle frame, and pass the inner packaging box through and mount it on the motorcycle frame from top to bottom, the third supporting foot and the fourth supporting foot on the top side of the inner packaging box respectively pass through the two lifting support ears at the rear end of the motorcycle frame until the third supporting foot and the fourth supporting foot are supported on the pad, and the fifth supporting foot is supported on the bottom wall of the outer packaging box, so that the motorcycle frame is located in the accommodating cavity, and the first limiting slot clamps the left and right support tubes at the rear end of the motorcycle frame downward to the pad, and the second limiting slot clamps the main tube at the front end of the motorcycle frame downward to the base, thereby limiting the motorcycle frame to the lower half of the accommodating cavity.

[0019] By adopting the above method, the inner packaging box is fully utilized, and the engagement and limitation of the motorcycle frame are achieved through the cooperation between the inner packaging box, the first limiting slot, the second limiting slot and the accommodating cavity. In terms of operational difficulty, the installation is simple and convenient, the assembly difficulty is low, and the fixing effect is good; and multiple inner packaging boxes can be placed in the outer packaging box at the same time, further improving the loading rate; the adjacent inner packaging boxes are arranged in opposite directions to avoid partial structures of adjacent motorcycle frames, such as the part of the lifting support ear extending outside the accommodating cavity, so that there is no need to space the inner packaging boxes and they can be placed next to each other, thereby adding more placement space in the outer packaging box and increasing the loading rate in the outer packaging box. The inner packaging boxes that are arranged next to each other support each other, and even if one of the inner packaging boxes is subjected to external pressure, its pressure can be dispersed through the adjacent inner packaging box, thereby increasing the strength of the bearing capacity of the overall structure.

[0020] A positioning groove is recessed downwardly at the position corresponding to the third supporting foot and the fourth supporting foot on the top surface of the cushion block, and a positioning column that is inserted into the positioning groove is vertically arranged at the bottom of the third supporting foot and the fourth supporting foot. In step S210, when the third supporting foot and the fourth supporting foot are supported on the cushion block, the positioning column is inserted into the positioning groove.

[0021] By adopting the above method, the lifting support ears of the motorcycle frame are raised so that the seat support is suspended. However, since some structures on the seat support are relatively fragile and easy to deform, raising the inner packaging box and the lifting support ears can avoid these parts of the structure and prevent them from deforming and affecting the appearance of the motorcycle frame, thereby causing losses to the manufacturer.

[0022] A third limit slot for limiting the horizontal movement of the rear end of the motorcycle frame is provided at a position on the top side of the inner packaging box corresponding to the rear end of the motorcycle frame, a fourth limit slot for limiting the horizontal movement of the front end of the motorcycle frame is provided at a position on the top side of the inner packaging box corresponding to the front end of the motorcycle frame, and a sixth support foot and a seventh support foot are formed on two lifting support ears corresponding to the front end of the motorcycle frame at positions on both sides of the third limit slot on the top side of the inner packaging box, respectively passing through the two lifting support ears, and the step S200 further includes the following sub-steps:

[0023] S220, place the top of the front end of the motorcycle frame downward, the bottom of the front end of the motorcycle frame and the rear end of the motorcycle frame upward, align the rear end of the motorcycle frame with the third limiting slot, align the top of the front end of the motorcycle frame with the fourth limiting slot, and insert the motorcycle frame into the accommodating cavity from top to bottom, the sixth supporting foot and the seventh supporting foot on the top side of the inner packaging box respectively pass through the two lifting support ears of the rear end of the motorcycle frame to clamp the left and right support tubes of the rear end of the motorcycle frame in the third limiting slot, and the main tube of the front end of the motorcycle frame is clamped in the fourth limiting slot, thereby limiting the motorcycle frame to the upper half of the accommodating cavity.

[0024] By adopting the above method, the motorcycle frame located in the upper part is supported, and at the same time, the motorcycle frame is restricted in the horizontal direction to prevent the motorcycle frame located in the upper part from moving in the horizontal direction, thereby increasing the stability of the motorcycle frame to a certain extent; and two motorcycle frames can be installed in one inner packaging box at the same time, thereby improving the loading rate of the inner packaging box, and although the inner packaging box can load two motorcycle frames at the same time, through the cooperation of the first limiting card slot, the second limiting card slot, the third limiting card slot and the fourth limiting card slot, the two motorcycle frames can be completely separated and not in contact with each other, and while improving the loading rate, the two motorcycle frames can also be limited and fixed separately to ensure the safety of the two motorcycle frames, so that the accommodating cavity and the inner packaging box are used more reasonably, saving costs to a certain extent.

[0025] The fourth limiting slot has, from top to bottom, a third slot section for limiting the horizontal movement of the bottom of the front end of the motorcycle frame and a fourth slot section for limiting the horizontal movement of the main pipe of the front end of the motorcycle frame. In the step S220, the main pipe of the front end of the motorcycle frame is clamped in the fourth slot section and the top of the front end of the motorcycle frame passes through the fourth slot section, so that the bottom of the front end of the motorcycle frame is supported in the third slot section to limit the up and down swinging of the motorcycle frame in the upper part of the accommodating cavity.

[0026] By adopting the above method, the fourth limiting slot can support the main pipe and the engine suspension plate combination at the same time, forming a double support for the motorcycle frame on the inner packaging box, while limiting the horizontal movement of the two ends of the main pipe, and cooperating with the third limiting slot to prevent the engine suspension plate combination from continuing to move outside the accommodating cavity, thereby improving the limiting capacity of the fourth limiting slot.

[0027] The pressing component includes an upper pressing plate that is through from top to bottom and is used to limit the movement of the inner packaging box in the vertical direction. A fifth limit slot for limiting the movement of the left and right support tubes in the vertical and horizontal directions is provided at a position corresponding to the left and right support tubes of the motorcycle frame on the bottom side of the upper pressing plate. A sixth limit slot for limiting the movement of the reinforcement plate in the vertical and horizontal directions is provided at a position corresponding to the reinforcement plate of the left and right support tubes on the bottom side of the upper pressing plate. The step S300 includes the following sub-steps:

[0028] S310, after aligning the fifth limit card slot with the corresponding left and right support tubes of the motorcycle frame and the sixth limit card slot with the corresponding reinforcement plate of the motorcycle frame, support the upper pressing plate from top to bottom on the top side of the inner packaging box, and set the fifth limit card on the left and right support tubes of the motorcycle frame, and set the sixth limit card slot on the reinforcement plate of the motorcycle frame, and make the outer packaging box fit the inner packaging box and the upper pressing plate therein to press the inner packaging box against the bottom wall of the outer packaging box and press the motorcycle frame into the accommodating cavity.

[0029] By adopting the above method, while the upper pressing plate presses the inner packaging box against the bottom wall of the outer packaging box, the motorcycle frame is also clamped and pressed against the inner packaging box, thereby ensuring the structural firmness and stability of the motorcycle frame and the inner packaging box at the same time, realizing multi-purpose integration.

[0030] The top side edge of the inner packaging box extends upward at a position corresponding to the upper pressing plate to form a tenth supporting foot for passing through the inner cavity of the upper pressing plate. The height of the tenth supporting foot in the vertical direction is the same as the height of the upper pressing plate. In step S300, when the upper pressing plate is supported from top to bottom on the top side edge of the inner packaging box, the tenth supporting foot is passed through the inner cavity of the upper pressing plate. When the outer packaging box is sleeved on the outer periphery of the inner packaging box and the upper pressing plate, the top side edge of the tenth supporting foot is pressed against the top wall of the outer packaging box.

[0031] By adopting the above method, the upper pressing plate can press the inner packaging box while the top wall of the outer packaging box presses the inner packaging box against the bottom wall of the outer packaging box, thereby achieving double compression.

[0032] The motorcycle frame packaging box and the packaging method thereof of the present invention have at least the following beneficial effects: through the coordinated use of the outer packaging box, the inner packaging box and the pressing component, the motorcycle frame is restricted from shaking in the horizontal and vertical directions, ensuring that the motorcycle frame will not shake relative to the packaging box even if the packaging box vibrates, hits, etc. during transportation, thereby effectively avoiding the possibility of damage to the motorcycle frame and ensuring the quality of the product; and the structure is simple, easy to assemble, low cost, and the materials are all recyclable, with high environmental performance.

[0047] The present invention will be further described below in conjunction with the accompanying drawings.

[0048] Reference Figure 1 , Figure 6 and Figure 7 The motorcycle frame 1 is of an existing structure and specifically includes a front end, a rear end, and left and right support pipes 14 respectively connected to the front end and the rear end at both ends. The front end of the motorcycle frame 1 includes a curved main pipe 12 and a frame riser 11 and an engine suspension plate assembly 16 respectively arranged at both ends of the main pipe 12. The rear end of the motorcycle frame includes a seat support 13 connected to the left and right support pipes 14. Two lifting support ears 15 are arranged on one end of the left and right support pipes 14 facing the seat support 13. For detailed structure, please refer to the utility model with patent number ZL200620110273.2, which will not be repeated here.

[0049] The motorcycle frame packaging box of the present invention specifically includes an outer packaging box 2 made entirely of corrugated paper, an inner packaging box 3 installed in the outer packaging box 2, and a pressing component 4 arranged in the outer packaging box 2 and located between the outer packaging box 2 and the top wall and the inner packaging box 3. The corrugated paper can be recycled to save costs and is green and environmentally friendly; the inner packaging box 3 is hollow inside and has an open top and bottom. A accommodating cavity 301 for installing a motorcycle frame 1 is formed on the inner side of the inner packaging box 3. The accommodating cavity 301 can be used to install the motorcycle frame 1 therein, and the pressing component 4 is used to press in the vertical direction. Inner packaging box 3 and motorcycle frame; when the motorcycle frame 1 is installed in the accommodating cavity 301 and the inner packaging box 3 is packed in the outer packaging box 2, the clamping component 4 and the inner packaging box 3 cooperate to limit the movement of the motorcycle frame 1 in the horizontal and vertical directions, so that the motorcycle frame 1 can be restricted from all directions so that it cannot shake relative to the packaging box. Compared with the existing packaging method, the present invention is specifically aimed at packaging the motorcycle frame 1, and starting from the structure of the motorcycle frame 1 itself, the stability and safety of the frame during transportation are guaranteed, and the motorcycle frame 1 is prevented from being damaged due to transportation.

[0050] Reference Figures 1 to 7 The packaging method of the present invention comprises the following three steps during packaging:

[0051] S100, placing the motorcycle frame 1 in the outer packaging box 2, and allowing the outer packaging box 2 to initially limit the motorcycle frame 1 in the horizontal direction;

[0052] S200, aligning the accommodating cavity 301 of the inner packaging box 2 with the motorcycle frame 1, and passing the inner packaging box 3 through the motorcycle frame 1 and then placing it in the outer packaging box 2, so that the motorcycle frame 1 is accommodated and confined in the accommodating cavity 301;

[0053] S300, put the outer packaging box 2 on the motorcycle frame 1 and the outer periphery of the inner packaging box 3, and press the inner packaging box 3 and the motorcycle frame 1 into the outer packaging box 2 in the vertical direction through the top wall of the outer packaging box 2 and a pressing component 4 below the top wall.

[0054] In this embodiment, the outer packaging box 2 includes a base 21 for supporting the inner packaging box 3, a panel 22 supported at the bottom on the base 21 and arranged around the outer wall of the inner packaging box 3, a top cover 23 covered on the top of the panel 22, and a limiting mechanism arranged on the base 21 corresponding to the installation area of ​​the motorcycle frame 1. The base 21 is used to support the panel 22 and the inner packaging box 3, the panel 22 is used to wrap the inner packaging box 3 from the side of the inner packaging box 3, and the top cover 23 covers the inner packaging box 3 from the top to achieve comprehensive packaging of the inner packaging box 3, and the sub-packaging outer packaging box 2 reduces the packaging difficulty, ensuring that the packaging process of the motorcycle frame 1 can be carried out in an orderly manner. The limiting mechanism is used to limit the movement of the motorcycle frame 1 in the horizontal direction, thereby reducing the possibility of collision between the motorcycle frame 1 and the outer packaging box 2.

[0055] The limiting mechanism includes a clamping structure arranged on the base 21 corresponding to the bottom of the front end of the motorcycle frame 1 for clamping the bottom of the front end of the motorcycle frame 1, a supporting structure arranged on the base 21 corresponding to the rear end of the motorcycle frame 1 for supporting the inner packaging box 3, and a positioning structure arranged between the supporting structure and the inner packaging box 3 for limiting the horizontal movement of the inner packaging box 3. The clamping structure is used to limit the motorcycle frame 1 on the base 21 to move partially in the horizontal direction, and the supporting structure is used to raise the inner packaging box 3 and the motorcycle frame 1, thereby reducing the contact between the motorcycle frame 1 and the outer packaging 2, and avoiding the deformation of the easily deformable structure on the motorcycle frame 1 due to collision with the outer packaging box 2, thereby affecting the quality of the motorcycle frame 1; the positioning structure is used to ensure that the inner packaging box 3 can accurately correspond to the area to be installed of the motorcycle frame 1, so that the positional relationship between the motorcycle frame 1 and the inner packaging box 3 can be kept unique, so that the installation of the motorcycle frame 1 is difficult to deviate, and the orderly progress of the packaging work is ensured. It should be noted that the structure of the limiting mechanism is not limited to the structure of the present embodiment, and other structures capable of limiting the position of the motorcycle frame may be used as a replacement. For example, in another embodiment, the limiting mechanism includes a base provided on the base 21, grooves provided at the top of the base along the outer contours of the front and rear ends of the motorcycle frame 1, and a clamping groove for clamping the inner packaging box 3 is provided on the base. When in use, the motorcycle frame 1 is first aligned with the groove and clamped in the groove, and then the inner packaging box 3 is mounted on the motorcycle frame 1 and clamped in the clamping groove, thereby completing the fixation of the motorcycle frame 1 and the inner packaging box 3.

[0056] The step S100 includes the following sub-steps:

[0057] S110, clamping the bottom of the front end of the motorcycle frame 1 in the clamping structure;

[0058] S120, supporting the rear end of the motorcycle frame 1 on the supporting structure.

[0059] In the present invention, the clamping structure includes a fixing block 25 arranged on the top surface of the bottom plate 213, and the fixing block 25 is arranged corresponding to the waiting area of ​​the engine suspension plate assembly 16 of the motorcycle frame 1 to be used to resist the engine suspension plate assembly 16, thereby limiting the movement of the motorcycle frame 1 from one direction.

[0060] A first slot 251 is formed on one side of the fixing block 25 facing the inner packaging box 3 and is consistent with the end contour of the engine suspension plate assembly 16 to clamp the engine suspension plate assembly 16. When the end of the engine suspension plate assembly 16 is engaged in the first slot 251, the end of the engine suspension plate assembly 16 is supported on the bottom plate 213. The bottom plate 213 and the fixing block 25 both provide support for the motorcycle frame 1. The first slot 251 positions and limits the motorcycle frame 1, so that the motorcycle frame 1 cannot move downward relative to the base 21.

[0061] In step S110, the engine suspension plate assembly 16 at the bottom of the front end of the motorcycle frame 1 and the left and right support tubes 14 at the rear end of the motorcycle frame 1 are facing downward, and the frame riser 11 at the top of the front end of the motorcycle frame 1 is facing upward, and the end of the engine suspension plate assembly 16 at the bottom of the front end of the motorcycle frame 1 is clamped in the first clamping groove 251 and abutted against the base 21; in step S120, the two lifting support ears 15 at the rear end of the motorcycle frame 1 are supported on the cushion block 26 so that the two lifting support ears 15 are spread out on the top of the cushion block 26, and the installation position of the motorcycle frame 1 is determined by the first clamping groove 251 of the fixing block 25 and the movement of the motorcycle frame 1 in a partial horizontal direction is restricted, so as to ensure that the motorcycle frame 1 can be accurately located in the planned installation area and the installation is carried out in an orderly manner.

[0062] In step S120, the supporting structure includes a pad 26 corresponding to the rear end of the motorcycle frame 1 and arranged on the base 21 on the bottom wall of the outer packaging box 2. The pad 26 is used to support the rear end of the motorcycle frame 1 so that the lifting support ear 15 at the rear end of the motorcycle frame 1 can be used as a support, and the seat cushion support 13 is kept away from the outer packaging box 2 and does not contact it, thereby reducing the possibility of damage to the motorcycle frame 1.

[0063] A working method of this embodiment is as follows: first, align the engine suspension plate assembly 16 of one of the motorcycle frames 1 with the first slot 251 on the fixing block 25 and make the engine suspension plate assembly 16 and one end of the seat cushion support 13 face downward, then abut and engage the engine suspension plate assembly 16 in the first slot 251, and naturally place one end of the seat cushion support 13 at the rear end of the motorcycle frame 1 on the pad 26. At this time, one side of the two sides of the end of the engine suspension plate assembly 16 is engaged with the first slot 251, and the other side abuts against the pad 26. The pad 26 supports the motorcycle frame 1, and the first slot 251 positions the motorcycle frame 1 and restricts the motorcycle frame 1 from moving in the front and rear directions.

[0064] In the present invention, a first clamping structure for limiting the movement of the motorcycle frame 1 is provided at positions corresponding to the front end and the rear end of the motorcycle frame 1 on the bottom side of the inner packaging box 3, the top of the first clamping structure is supported on the cushion block 26, and a fifth supporting foot 309 supported on the base 21 and used to keep the first clamping structure away from the base 21 is protruded downward at the bottom position of the first clamping structure on the inner packaging box 3; and a fifth supporting foot 309 for limiting the movement of the motorcycle frame 1 is provided at positions corresponding to the front end and the rear end of the motorcycle frame 1 on the top side of the inner packaging box 3. The second clamping structure for moving the frame 1, the second clamping structure and the first clamping structure divide the accommodating cavity 301 into two installation cavities, one above and one below, for respectively installing the motorcycle frame 1. When the fifth supporting foot 309 is supported on the base 21, one side of the bottom side of the inner packaging box 3 is supported on the supporting structure, and the other side of the bottom side of the bottom side of the inner packaging box 3 is suspended above the fixed block 25 of the clamping structure. After the motorcycle frame 1 is installed, the suspended part can avoid part of the structure of the motorcycle frame 1, thereby reducing the contact between the motorcycle frame 1 and the inner packaging box 2. After the installation is completed, the first clamping structure limits the motorcycle frame 1 to the installation cavity below, and the second clamping structure limits the motorcycle frame 1 to the installation cavity above, so that the upper part of the inner packaging box 3 can also be equipped with a motorcycle frame 1 and fix and limit it. In this way, two motorcycle frames 1 can be installed simultaneously in the accommodating cavity 301 of an inner packaging box 3, and the two motorcycle frames 1 are fixed and supported by the inner packaging box 3, the clamping component 4, the first clamping structure and the second clamping structure.

[0065] Specifically, the first clamping structure includes a first limit clamping slot 51 provided at a position corresponding to the rear end of the motorcycle frame 1 on the bottom side of the inner packaging box 3 and a second limit clamping slot 52 provided at a position corresponding to the top of the front end of the motorcycle frame 1 on the bottom side of the inner packaging box 3, the first limit clamping slot 51 is used to limit the rear end of the motorcycle frame 1 from moving upward in the vertical direction, and the second limit clamping slot 52 is used to limit the front end of the motorcycle frame 1 from moving upward in the vertical direction. The second clamping structure includes a third limit clamping slot 53 provided at a position corresponding to the rear end of the motorcycle frame 1 on the top side of the inner packaging box 3 and a fourth limit clamping slot 54 provided at a position corresponding to the front end of the motorcycle frame 1 on the top side of the inner packaging box 3, the third limit clamping slot 53 is used to limit the rear end of the motorcycle frame 1 from moving in the horizontal direction, and the fourth limit clamping slot 54 is used to limit the front end of the motorcycle frame 1 from moving in the horizontal direction.

[0066] Furthermore, at the positions on both sides of the first limiting slot 51 on the bottom side of the inner packaging box 3, two vehicle lifting support ears 15 corresponding to the rear end of the motorcycle frame 1 are formed with a third supporting foot 307 and a fourth supporting foot 308 that pass through the two vehicle lifting support ears 15 respectively; at the positions on both sides of the third limiting slot 53 on the top side of the inner packaging box 3, two vehicle lifting support ears 15 corresponding to the front end of the motorcycle frame 1 are formed with a sixth supporting foot 310 and a seventh supporting foot 311 that pass through the two vehicle lifting support ears 15 respectively, so that when the inner packaging box 3 is mounted on the motorcycle frame 1, the vehicle lifting support ears 15 can be inserted into the vehicle lifting support ears 15 without affecting the installation of the motorcycle frame 1, thereby avoiding interference with the motorcycle frame 1.

[0067] The step S200 includes the following sub-steps:

[0068] S210, make the accommodating cavity 301 of the inner packaging box 3 be located just above the motorcycle frame 1, align the first limiting card slot 51 with the front end of the motorcycle frame 1, align the second limiting card slot 52 with the rear end of the motorcycle frame 1, and make the inner packaging box 3 pass through and be erected on the motorcycle frame 1 from top to bottom, the third supporting leg 307 and the fourth supporting leg 308 on the top side of the inner packaging box 3 respectively pass through the two lifting support ears 15 at the rear end of the motorcycle frame 1 until the third supporting leg 307 and the fourth supporting leg 308 are supported on the cushion block 26, and the fifth supporting leg 309 is supported on the bottom wall of the outer packaging box 2, so that the motorcycle frame 1 is located in the accommodating cavity 301, and the first limiting card slot 51 clamps the left and right support pipes 14 at the rear end of the motorcycle frame 1 downward to the cushion block 26, and the second limiting card slot 52 clamps the main pipe 12 at the front end of the motorcycle frame 1 downward to the base 21, so that the motorcycle frame 1 is limited to the lower half of the accommodating cavity 301;

[0069] S220, turn the top of the front end of the motorcycle frame 1 downward, turn the bottom of the front end of the motorcycle frame 1 and the rear end of the motorcycle frame 1 upward, align the rear end of the motorcycle frame 1 with the third limiting slot 53, align the top of the front end of the motorcycle frame 1 with the fourth limiting slot 54, and insert the motorcycle frame 1 into the accommodating cavity 301 from top to bottom, the sixth supporting leg 310 and the seventh supporting leg 311 on the top side of the inner packaging box 3 respectively pass through the two lifting support ears 15 at the rear end of the motorcycle frame 1 to clamp the left and right support pipes 14 at the rear end of the motorcycle frame 1 in the third limiting slot 53, and the main pipe at the front end of the motorcycle frame 1 is clamped in the fourth limiting slot 54, thereby limiting the motorcycle frame 1 to the upper half of the accommodating cavity 301.

[0070] In this embodiment, a plurality of inner packaging boxes 3 are arranged and placed adjacent to each other, and the adjacent inner packaging boxes 3 are oriented in opposite directions. The fixing blocks 25 and the cushion blocks 26 are respectively arranged corresponding to the inner packaging boxes 3 to correspond one-to-one with the inner packaging boxes 3 .

[0071] Specifically, the inner packaging box 3 is formed by a front side panel 302, a left side panel 303, a rear side panel 304 and a right side panel 305 connected in sequence, and the front side panel 302, the left side panel 303, the rear side panel 304 and the right side panel 305 correspond to the front, left, rear and right directions respectively, and the accommodating cavity 301 is an inner cavity formed by the front side panel 302, the left side panel 303, the rear side panel 304 and the right side panel 305 and is in the shape of a rectangular parallelepiped, and the fixing block 25 corresponds to the outer side of the left side panel 303 and is arranged adjacent to the left side panel 303.

[0072] As a preferred embodiment of the present invention, the portions of the front side plate 302 and the rear side plate 304 located between the seventh limiting slot 55 and the eighth limiting slot 56 extend downward to form fifth supporting feet 309, respectively. The bottom side of the fifth supporting feet 309 is lower than the bottom side of each supporting foot. The positioning structure includes positioning columns respectively arranged at the bottom of the third supporting feet 307 and the fourth supporting feet 308, and positioning grooves 261 that are arranged at both ends of the cushion block 26 and located at the positions of the two positioning columns on the top surface and that are upwardly penetrating. In step S210, when the third supporting feet 307 and the fourth supporting feet 308 are supported on the cushion block 26, the positioning columns are inserted into the positioning grooves 261.

[0073] The first limit card slot 51 is arranged on the right side plate 305, and the second limit card slot 52 is arranged on the left side plate 303 to correspond. The first clamping structure also includes two seventh limit card slots 55 and two eighth limit card slots 56 which are respectively arranged on the bottom sides of the front side plate 302 and the rear side plate 304 of the inner packaging box 3 and are concave upwards in sequence. The second limit card slot 52, the seventh limit card slot 55, the eighth limit card slot 56 and the first limit card slot 51 are all connected to the accommodating cavity 301 and the outer side of the inner packaging box 3 to form a gap shape; that is, the seventh limit card slot 55 and the eighth limit card slot 56 are both provided on the front side plate 302 and the rear side plate 304, and the seventh limit card slot 55 and the eighth limit card slot 56 are consistent in shape and size and are both rectangular. The second limiting slot 52 has a first slot section 521 and a second slot section 522 from bottom to top. The first slot section 521 and the first limiting slot 51 have the same shape and size and are both rectangular structures. The second slot section 522 is configured to gradually narrow from bottom to top. In this way, when the inner packaging box 3 is placed on the motorcycle frame 1, the spacious opening can facilitate the motorcycle frame 1 to enter the second slot section 522, and the gradually narrowing setting facilitates the motorcycle frame 1 to gradually locate at a predetermined position, and can gradually clamp the motorcycle frame 1 according to its size, thereby realizing the positioning and limiting of the motorcycle frame 1. The left side plate 303 and the front side plate 302 part between the first groove section 521 and the seventh limiting slot 55 of the front side plate 302 are the first supporting foot 306, and the first supporting foot 306 can pass through the inner side of one of the lifting support ears 15 of the motorcycle frame 1; the rear side plate 304 and the left side plate 303 part between the first groove section 521 and the seventh limiting slot 55 on the rear side plate 304 are the second supporting foot, and the second supporting foot can pass through the inner side of another lifting support ear 15 of the motorcycle frame 1; and the use of the first limiting slot 51 and the second limiting slot 52 is the same, that is, the front side plate 302 and the right side plate 305 part between the first limiting slot 51 and the eighth limiting slot 56 of the front side plate 302 are the third supporting foot 307, and the third supporting foot 307 can pass through the motorcycle The inner side of one of the lifting support ears 15 of the motorcycle frame 1; the rear side plate 304 and the right side plate 305 part between the first limiting slot 51 and the eighth limiting slot 56 of the rear side plate 304 are the fourth supporting foot 308, and the fourth supporting foot 308 can pass through the inner side of another lifting support ear 15 of the motorcycle frame 1, so that when several adjacent inner packaging boxes 3 are installed in the outer packaging box 2, each adjacent supporting foot can pass through the lifting support ear 15 of the motorcycle frame 1, avoiding the need to increase the placement space due to the presence of the lifting support ear 15 affecting the placement of the inner packaging box 3. The arrangement of this embodiment can enable several inner packaging boxes 3 to be placed adjacent to each other without being spaced apart, thereby increasing the loading rate of the outer packaging box 2, thereby reducing the use of the outer packaging box 2 and saving costs for merchants.

[0074] In the step S210 , the portion of the inner packaging box 3 corresponding to the portion between the second limiting slot 52 and the seventh limiting slot 55 is suspended during installation to avoid the structure of the engine suspension plate assembly 16 .

[0075] The third limiting slots 53 are provided in two and are recessed downward on the top side of the left side plate 303 to support and clamp the two seat cushion supports 13 of the motorcycle frame 1, and the fourth limiting slot 54 is recessed downward on the top side of the right side plate 305 to support the main pipe 12. The second clamping structure also includes two ninth limiting slots 57 and two tenth limiting slots 58 which are recessed downward on the top sides of the front side plate 302 and the rear side plate 304 and are symmetrically arranged. The third limit slot 53, the ninth limit slot 57, the tenth limit slot 58 and the fourth limit slot 54 are all connected to the accommodating cavity 301 and the outer side of the inner packaging box 3 to form a notch shape, that is, the ninth limit slot 57 and the tenth limit slot 58 are provided on the front side plate 302 and the rear side plate 304, and the cooperation between the third limit slot 53 and the fourth limit slot 54 is used to limit the horizontal movement of the motorcycle frame 1 located in the upper part, and the cooperation between the clamping component 4 and the inner packaging box 3 further limits the movement of the motorcycle frame 1 in the up and down directions, thereby limiting the movement of the motorcycle frame 1 in all directions and ensuring that the motorcycle frame 1 will not shake relative to the outer packaging box 2.

[0076] Specifically, the two third limit slots 53 are both set to be gradually narrowed from top to bottom so as to better clamp the cushion support 13. The third limit slots 53 can also be directly opened along the outer contour of the cushion support 13 so as to better clamp the cushion support 13. The ninth limit slot 57 and the tenth limit slot 58 are of the same shape and size and are both rectangular. The fourth limit slot 54 has a third slot section 541 and a fourth slot section 542 from top to bottom. The third slot section 541 is rectangular and is used for the engine suspension plate assembly 16 to pass through the accommodating cavity 301 and to support the engine suspension plate assembly 16 from below, thereby providing a support point for the engine suspension plate assembly 16. The fourth slot section 542 is gradually narrowed from top to bottom and the width of the top is smaller than the width of the third slot section 541, so that the main pipe 12 and the frame riser 11 can better pass through the accommodating cavity 301 and clamp the main pipe 12 from below the main pipe 12, and an opening is provided on one side wall of the fourth slot section 542 along the outer contour of the frame riser 11 to avoid it so that it can be located exactly there. The left side plate 303 and the front side plate 302 portion between the third limiting slot 53 and the ninth limiting slot 57 of the front side plate 302 is the fifth supporting foot 309, and the fifth supporting foot 309 can pass through the inner side of one of the lifting support ears 15 of the motorcycle frame 1; the rear side plate 304 and the left side plate 303 portion between the third limiting slot 53 and the ninth limiting slot 57 on the rear side plate 304 is the seventh supporting foot 311, and the seventh supporting foot 311 can pass through the inner side of the other lifting support ear 15 of the motorcycle frame 1; the front side plate 302 and the right side plate 305 portion between the fourth limiting slot 54 and the tenth limiting slot 58 of the front side plate 302 is The eighth supporting foot 312 can pass through the inner side of one of the lifting support ears 15 of the motorcycle frame 1; the rear side plate 304 and the right side plate 305 part between the fourth limiting slot 54 and the tenth limiting slot 58 of the rear side plate 304 are the ninth supporting foot 313, and the ninth supporting foot 313 can pass through the inner side of another lifting support ear 15 of the motorcycle frame 1, so that when several adjacent inner packaging boxes 3 are installed in the outer packaging, each adjacent supporting foot can pass through the lifting support ear 15 of the motorcycle frame 1, thereby avoiding the need to increase the placement space due to the presence of the lifting support ear 15 affecting the placement of the inner packaging box 3.

[0077] Preferably, the right side plate 305 of the present invention is a multi-layer stacking design, and its thickness is greater than that of the front side plate 302 and the rear side plate 304. The position corresponding to the third limit slot 53 on the left side plate 303 is also a multi-layer stacking design. Since the third limit slot 53 and the fourth limit slot 54 are used to support the motorcycle frame 1, the firmness of their structure is particularly critical, and the inner packaging box 3 is also made of corrugated paper, which has limited hardness. The stacking design can increase the hardness of the inner packaging box 3 to increase the third limit slot 54. 3 and the fourth limit slot 54, and the front side plate 302 and the rear side plate 304 are not structures that directly support the motorcycle frame 1, so their functions can be achieved even without a stacking design; and a plurality of inner packaging boxes 3 are arranged in an outer packaging box 2, and each inner packaging box 3 is arranged adjacent to each other, so that adjacent inner packaging boxes 3 are arranged in contact with each other, and the front side plate 302 and the rear side plate 304 after being attached form a stacking structure, which can optimize the hardness of the front and rear side plates 304 and improve the overall firmness of the inner packaging box 3.

[0078] In this embodiment, the adjacent inner packaging boxes 3 are arranged in opposite directions, that is, the left side plate 303 and the right side plate 305 of any inner packaging box 3 adjacent to it are in opposite positions, and the front side plate 302 and the rear side plate 304 are in opposite positions. Since the lifting support ears 15 of each motorcycle frame 1 will extend to the outside of the corresponding accommodating cavity 301 through each supporting foot when installed in the accommodating cavity 301, and the inner packaging boxes 3 are arranged adjacent to each other, if they are arranged in the same direction, the lifting support ears 15 between adjacent motorcycle frames 1 will interfere with each other and cannot be placed, and the spacing needs to be increased to achieve It is now found that increasing the spacing will take up more space and reduce the placement of the inner packaging box 3, while placing in the opposite direction can avoid this problem, so that the motorcycle frame 1 in the adjacent inner packaging boxes 3 is located in two different directions so as not to interfere with each other, and the symmetrical arrangement between each seventh limit slot 55 and the eighth limit slot 56 and the symmetrical arrangement between each ninth limit slot 57 and the tenth limit slot 58 can overlap each other when the adjacent inner packaging boxes 3 are placed next to each other, so as not to affect the placement of the motorcycle frame 1, making the design more reasonable and the structure more exquisite. Correspondingly, the arrangement of the fixing block 25 and the cushion block 26 are all in one-to-one correspondence with each inner packaging box 3, and the positions of the fixing blocks 25 and cushion blocks 26 corresponding to the adjacent inner packaging boxes 3 are also opposite.

[0079] The working method of this embodiment is as follows: the inner packaging box 3 is moved downward after the second limiting slot 52 of the inner packaging box 3 is aligned with the main pipe 12 and the first limiting slot 51 is aligned with the cushion support 13. During the downward movement of the inner packaging box 3, the main pipe 12 moves toward the second slot section 522, and the cushion support 13 moves toward the fourth slot section 542, and the third supporting leg 307 and the fourth supporting leg 308 are respectively inserted into the inner sides of the two vehicle lifting support ears 15 until the first supporting leg 306, the second supporting leg 306, the third supporting leg 307 and the fourth supporting leg 308 are against the bottom plate 213; at this time, the second slot section 522 clamps the upper end of the main pipe 12 to cooperate with the fixing block 25 and the bottom plate 213 to limit the engine suspension plate assembly 16 and one side of the main pipe 12 from moving in the up and down directions, front and back directions and When the motorcycle frame 1 moves toward the left side, a part of the frame riser 11 passes through the second limiting slot 52 to be suspended in the air; and the first limiting slot 51 abuts against the seat support 13 from top to bottom to press the seat support 13, so that while the engine suspension plate assembly 16 of the motorcycle frame 1 and one end of the frame riser 11 are restricted, one end of the seat support 13 cannot move in the up and down directions and toward the right side. At this time, the motorcycle frame 1 is located in the lower half of the inner packaging box 3. After the inner packaging box 3 is restricted by the pressing component 4 and the outer packaging box 2, the motorcycle frame 1 is restricted in all directions, ensuring that the position of the motorcycle frame 1 relative to the outer packaging box 2 remains unchanged during transportation without colliding with the packaging, thereby avoiding the adverse conditions that occur in the traditional packaging method of the motorcycle frame 1.

[0080] Specifically, the pressing component 4 includes an upper pressing plate 41 that is located between the second clamping structure and the top wall of the outer packaging box 2 and is through-through, and a third clamping structure 42 formed on the bottom side of the upper pressing plate 41 for pressing against the inner packaging box 3 and the motorcycle frame 1. The upper pressing plate 41 is a rectangular frame structure with four sides. The length direction of the upper pressing plate 41 is arranged along the sequential placement direction of each inner packaging box 3 and the length is greater than the sum of the thicknesses of each inner packaging box 3 in the sequential placement direction, so that the upper pressing plate 41 can press all the inner packaging boxes 3 without being separately arranged for each inner packaging box 3. The portion between the front side plate 302 and the rear side plate 304 between each ninth limiting slot 57 and the tenth limiting slot 58 extends upward to form a tenth supporting foot 314. The top side height of the tenth supporting foot 314 is higher than the sixth supporting foot 310, the seventh supporting foot 311, the eighth supporting frame and the ninth supporting foot 313. The tenth supporting foot 314 can be movably inserted into the inner cavity of the upper pressing plate 41 and abut against the top cover 23 when the motorcycle frame 1 is packed. In this way, the fifth supporting foot 309 and the tenth supporting foot 314 of the entire inner packaging box 3 abut against the bottom plate 213 and the top cover 23 respectively during packaging. The inner packaging box 3 is pressed by the top cover 23 and the base 21 and cannot be flipped or moved relative to the outer packaging box 2. The outer packaging box 2 and the inner packaging box 3 cooperate with each other to ensure the stability of the inner packaging box 3.

[0081] The third clamping structure 42 includes a fifth limiting slot 421 formed on the bottom side of the upper pressing plate 41 corresponding to the fourth limiting slot 54 for clamping the left and right support tubes 14, and two sixth limiting slots 422 formed on the bottom side of the upper pressing plate 41 corresponding to the third limiting slot 53 for clamping the two reinforcing plates 17. The fifth limiting slot 421 is located on the same side as the fourth limiting slot 54 to correspond to each other, and the sixth limiting slot 422 is located on the same side as the third limiting slot 53 to correspond to each other. The fifth limiting slot 421 and the sixth limiting slot 422 are both located directly above the accommodating cavity 301, and the number of the fifth limiting slot 421 and the sixth limiting slot 422 respectively corresponds to the number of the inner packaging boxes 3 so that they can be used to press the motorcycle frame 1 on the upper half of each inner packaging box 3. It should be noted that the detailed structure of the clamping component 4 and the third clamping structure 42 is not limited to the present embodiment, and other structures capable of achieving the same function may be used to replace them. For example, the clamping component 4 includes a clamping block arranged on the top of the inner packaging box 3, and the bottom of the clamping block is provided with a second clamping groove along the bottom of the front end and the outer contour of the rear end of the motorcycle frame 1 located in the upper mounting cavity. The third clamping structure 42 includes a third clamping groove provided at the bottom of the clamping block for clamping on the inner packaging box 3. During installation, the second clamping groove of the clamping block is aligned with the motorcycle frame 1, and the third clamping groove is aligned with the inner packaging box 3. Then, the second clamping groove is covered and clamped on the motorcycle frame 1, and the clamping block is clamped on the inner packaging box 3. The clamping block can press the motorcycle frame 1 without cooperating with the outer packaging box 2.

[0082] Reference Figure 4 , step S300 includes the following sub-steps:

[0083] S310, after aligning the fifth limiting slot 421 with the corresponding left and right support tubes 14 of the motorcycle frame 1 and aligning the sixth limiting slot 422 with the corresponding reinforcing plate 17 of the motorcycle frame 1, the upper pressing plate 41 is supported on the top side of the inner packaging box 3 from top to bottom, and the fifth limiting slot 421 is clamped on the left and right support tubes 14 of the motorcycle frame 1, and the sixth limiting slot 422 is clamped on the reinforcing plate 17 of the motorcycle frame 1, and the outer packaging box 2 is used to insert the inner packaging box 3 and the upper pressing plate 41 therein to press the inner packaging box 3 against the bottom wall of the outer packaging box 2 and press the motorcycle frame 1 into the accommodating cavity 301.

[0084] In step S300, the base 21 includes a tray 211 with strip-shaped edges at the bottom, a bottom cover 213 arranged on the top of the tray 211, and a bottom plate 213 placed inside the bottom cover 213. The tray 211, the bottom cover 213, and the bottom plate 213 are all rectangular. The edges are arranged in at least three and support the tray 211 to raise the tray 211, so that the packing tape passes through the gaps between the edges at the bottom of the base 21 when the entire outer packaging box 2 is packed. The bottom cover 213 is hollow inside and the top is open upward to be surrounded on the bottom plate 213. The inner packaging box 3 is placed on the bottom plate 213. The bottom cover 213, the tray 211, and the edges are connected and fixed from top to bottom by corrugated umbrella nails. At least one limiting strip 24 is arranged on both sides of the top of the bottom plate 213, and the limiting strips 24 on both sides are symmetrically arranged and the opposite side is flush with the edge of the corresponding side of the bottom plate 213. The fixing block 25 is located between the limiting strips 24 on both sides. When the bottom of the enclosure 22 is supported on the bottom cover 213 for enclosing the inner packaging box 3, the limiting strip 24 limits the position of the enclosure 22, so that the enclosure 22 is located between the limiting strip 24 and the side enclosure of the bottom cover 213 during assembly to position the enclosure 22, thereby simplifying the installation of the enclosure 22.

[0085] Reference Figure 3The enclosure 22 is formed by an outer plate with a head end and a tail end, and the head end and the tail end of the outer plate are detachably connected through a connecting portion. During the packaging process, after the head end and the tail end of the outer plate are disassembled and separated, it can be packaged more simply by gradually surrounding from the side. If the head end and the tail end are fixedly connected, during installation, it can only be installed from top to bottom and the edge must be accurately aligned with the area to be placed to complete the installation. The method of surrounding from the side only requires positioning the position of one side, and the other side is extended along the side of the bottom cover 213. Even if the outer plate is not placed properly, it can be adjusted, which is more convenient to use and more flexible. The outer plate is in the shape of a rectangular parallelepiped and has four side surfaces connected in sequence. Adjacent side surfaces can be bent. One side of the two side surfaces located at the end of the four side surfaces is the head end and the tail end of the outer plate. The head end and the tail end are connected to form a rectangular frame structure. On the head end, it extends toward the side away from the head end to form a connecting plate 221. The connecting part includes a mother buckle arranged on the connecting plate 221 and a sub buckle arranged on the tail end and engaged with the mother buckle. When in use, the connection between the head end and the tail end of the outer plate can be completed by simply engaging the sub buckle and the mother buckle. The installation and disassembly are very convenient and the cost is relatively low. The sub buckle and the mother buckle are both existing conventional sub buckles and mother buckles, which will not be described here. It should be noted that the connecting plate 221 can also be arranged on the tail end without affecting the connection effect; the connecting part is not limited to the structure of this embodiment, and can also be replaced by other structures, such as replacing the sub buckles of the connecting part with magnetic blocks, and fixing the magnetic blocks on the head end and the tail end of the outer plate respectively, so as to achieve a detachable connection by magnetic attraction, and it is also convenient to use. When using this embodiment, the four sides of the outer plate are inserted into the side enclosures of the bottom cover 213 and the limiting strips 24 in sequence until the four sides are in contact with the four side enclosures of the bottom cover 213, and then the male and female buckles are buckled to complete the installation between the enclosure 22 and the base 21. The side edge of the top cover 23 extends downward to form a side rib. When packing, the installation of the top cover 23 is the last step. It is placed on the top outer side of the enclosure 22, and then the packing tape is used to pack to complete the entire process.

[0086] The working method of this embodiment is as follows: after the motorcycle frame 1 located at the lower half is installed, first, one end of the frame riser 11 of the other motorcycle frame 1 is facing downward, one end of the seat support 13 and one end of the engine suspension plate assembly 16 are facing upward, and then the main pipe 12 is aligned with the fourth groove section 542, the seat support 13 is aligned with the third limit slot 53, and then the motorcycle frame 1 is moved downward, so that the main pipe 12 is clamped in the fourth groove section 542 and the frame riser 11 passes through the accommodating cavity 301, and the seat support 13 is clamped in the third limit slot 53. At this time, the end of the engine suspension plate assembly 16 extends out of the third groove section 541, and the middle part of the engine suspension plate assembly 16 rests on the bottom side of the third groove section 541; at the same time, the two lifting support ears 15 are respectively covered on the sixth support foot 310, the seventh support foot 311 and the adjacent inner packaging box 3 On the eighth supporting foot 312 and the ninth supporting foot 313, the third limiting slot 53 and the fourth limiting slot 54 can limit the motorcycle frame 1 located in the upper part to prevent it from moving in the horizontal direction; then use other inner packaging boxes 3 to repeat the installation of the upper and lower parts of the motorcycle frame 1 in sequence until the base 21 can no longer place the inner packaging box 3, align the fifth limiting slot 421 on the upper pressing plate 41 with the left and right support tubes 14, align the sixth limiting slot 422 with the reinforcing plate 17 and install them relatively, the bottom side edges of the two side surfaces of the upper pressing plate 41 provided with the fifth limiting slot 421 and the sixth limiting slot 422 respectively abut against the bottom sides of the ninth limiting slot 57 and the tenth limiting slot 58; finally, surround the enclosure 22 and connect the head and tail ends of the enclosure 22, cover the top cover 23 and use the packing tape to pack. At this time, the ends of the inner packaging box 3 and the engine suspension plate assembly 16 of the motorcycle frame 1 located in the lower part are both pressed against the bottom plate 213, and the top cover 23 presses the upper pressing plate 41 so that the upper pressing plate 41 presses the motorcycle frame 1 and the inner packaging box 3 located in the upper part against the bottom plate 213, and the pressed inner packaging box 3 presses the motorcycle frame 1 located in the lower part downward, so that all the motorcycle frames 1 can be restricted as a whole, so that each motorcycle frame 1 is firmly restricted in the outer packaging box 2 and cannot swing relative to the outer packaging box 2, with high stability, avoiding the appearance of the motorcycle frame 1 being scratched or other adverse phenomena caused by vibration, impact, etc. of the outer packaging box 2 during transportation; the entire installation process is simple and easy to assemble, and can be operated by one person, which reduces the cost of manual assembly to a certain extent; and all the packaging structures of the present invention are made of corrugated paper, which is not only low in cost, but also recyclable after use, with high environmental protection.
