Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle parts packaging, in particular to a frame sub-assembly packaging base. Background Art

[0002] The frame sub-assembly, also known as the seat tube and front support tube assembly, is a key component at the front of a motorcycle frame. The front seat tube is connected to the outside of the steering tube, and the upper end of the front support tube supports and installs the engine. Therefore, it is particularly important to maintain the integrity of the frame sub-assembly during packaging and transportation.

[0003] The existing packaging method for motorcycle frame subassemblies involves wrapping the frame subassembly in bubble wrap, placing it in a paper-padded box, and then placing it directly into the cardboard box. The box is then covered with a lid and packaged for shipment. Because the frame subassembly is a tubular structure with a number of easily deformable lugs or wire frames on its surface, the frame subassembly is prone to movement within the box during transportation, resulting in damage and economic losses. Some existing packaging boxes have a slotted top retaining bar at the bottom, into which components are inserted from top to bottom. While this improves component stability, vertical movement and loosening are still possible, and bumps cannot be completely prevented. Utility Model Content

[0038] The bending auxiliary part 5 is arranged on the second limiting part 12 and the third limiting part 13.

[0039] The use principle of the utility model is as follows:

[0040] As shown in Figure 1 and Figure 6 At least two limiting units are arranged on the cover part 1, the cover part 1 is used for supporting the bottom of the packaging box, and when the frame subassembly is packaged, the cover part 1 is combined with other packaging parts to complete packaging through a packing rope, so that the frame subassembly is packaged in the cover part 1, and the bottom of the frame subassembly is prevented from contacting the ground.

[0041] First, the cover portion 1 includes a bottom support plate 10, which is a rectangular structure and can be a square or a rectangle as needed. A first panel 101, a second panel 102, a third panel 103 and a fourth panel 104 are formed integrally at the edge of the bottom support plate 10. The bottom support plate 10 and the four panels are arranged to form a cavity structure with an open top. The two ends of the third panel 103 intersect with the same-direction ends of the first panel 101 and the second panel 102, and the two ends of the fourth panel 104 intersect with the same-direction ends of the first panel 101 and the second panel 102, respectively. The first and second panels 101 and 102 intersect at the ends, and end panels 116 are provided at the corresponding intersection positions on the first and second panels 101 and 102, and the end panels 116 at the corresponding ends are connected to the corresponding third panel 103 or fourth panel 104 by gluing or nailing with metal nails. Hand holes 105 are symmetrically opened on the two panels, such as the first and second panels 101 and 102, and also on the third and fourth panels 103 and 104, so that the handling personnel can increase the gripping force between the packaging base and the hand through the hand holes 105, so that the handling personnel can move the packaging base. It should be noted that the horizontal direction in this embodiment refers to the first limiting portion 11 and the length and width direction, and the vertical direction refers to the vertical direction or height direction.

[0042] Next, each limiting unit includes a first limiting portion 11 for fixing and laterally limiting one side of the frame sub-assembly, and a second limiting portion 12 arranged parallel to the first limiting portion 11 and laterally limiting the other side of the frame sub-assembly. A third limiting portion 13 is provided between the first limiting portion 11 and the second limiting portion 12, which are parallel to each other and vertically limit the middle part of the frame sub-assembly. When the frame sub-assembly is installed on the first limiting portion 11, the second limiting portion 12 and the third limiting portion 13, the freedom of the frame sub-assembly can be fully limited in the lateral and vertical directions, preventing the frame sub-assembly from moving up and down or shaking laterally during transportation, thereby improving packaging stability and ensuring transportation safety of the frame sub-assembly.

[0043] Among them, such as Figure 1 and Figure 2 As shown, the first limiting portion 11 includes a first pressing plate 110 made of corrugated paper, a first folding structure formed on the first pressing plate 110, and a first transverse limiting structure formed on the first pressing plate 110. The first pressing plate 110 cooperates with the first folding structure to fold into a tubular structure, which is not only low-cost but also simple and convenient to manufacture. The first transverse limiting structure is used to limit and fix one end of the frame sub-assembly in the transverse direction, thereby preventing the frame sub-assembly from shaking in the transverse direction and causing collision damage.

[0044] The first pressing plate 110 is in a rectangular sheet structure, and the lower end of the tubular structure after folding of the first pressing plate 110 is fixedly connected to the bottom supporting plate 10, and the left and right ends of the tubular structure are respectively abutted with the third surrounding plate 103 and the fourth surrounding plate 104, so as to increase the bearing capacity of the entire packaging bottom support and improve the firmness of the packaging.

[0045] In the assembling of the first limiting part 11, the first side plate 21 and the second side plate 22 are respectively vertically downwardly bent along the first folding line 112 on the corresponding side of the first top plate 31, the first bottom plate 41 is transversely bent toward the side of the first side plate 21 along the first folding line 112 between the second side plate 22, the third side plate 23 is vertically upwardly bent along the first folding line 112 between the first bottom plate 41 and is laminated on the inner side of the first side plate 21 to form a square tube, and the laminated first side plate 21 and the third side plate 23 are connected and fixed by nailing; wherein the first clamping groove 111 comprises a first strip-shaped groove 111a provided through the first side plate 21, the first top plate 31 and the second side plate 22, and a second strip-shaped groove 111b provided on the third side plate 23 at a position corresponding to the first strip-shaped groove 111a, and the second strip-shaped groove 111b and the first strip-shaped groove 111a are throughly combined to form the first clamping groove 111 when the first pressing plate 110 is folded into a tubular structure.

[0046] In addition, the thickness dimension of the first pressing plate 110 should be set such that when the frame subassembly is placed on one side in the first clamping groove 111, the plane where the upper end of the frame subassembly is located is lower than or flush with the plane where the upper end of the first top plate 31 is located, preferably, the plane where the upper end of the frame subassembly is located is lower than the plane where the upper end of the first top plate 31 is located, so as to avoid extrusion and bruising when the stacked packages are stacked.

[0047] Similarly, as shown in Figure 1 and Figure 3 , the second limiting part 12 comprises a second pressing plate 120 made of corrugated paper, a second folding structure formed on the second pressing plate 120, and a second transverse limiting structure formed on the second pressing plate 120, the second pressing plate 120 is also folded into a tubular structure in cooperation with the second folding structure, and the second transverse limiting structure is used to limit and fix one end of the frame subassembly in the transverse direction, so as to prevent the frame subassembly from shaking in the transverse direction and being damaged by knocking.

[0048] The second pressing plate 120 is in a rectangular sheet structure, and the lower end of the tubular structure after folding of the second pressing plate 120 is fixedly connected to the bottom supporting plate 10, and the left and right ends of the tubular structure are respectively abutted with the third surrounding plate 103 and the fourth surrounding plate 104, so as to increase the bearing capacity of the entire packaging bottom support and improve the firmness of the packaging.

[0049] When the second limiting portion 12 is assembled, the fourth side panel 24 is bent vertically downward along the second folding line 122 between the fourth side panel 24 and the second top panel 32, the second bottom panel 42 is bent laterally toward the side of the fifth side panel 25 along the second folding line 122 between the fourth side panel 24, and the fifth side panel 25 is bent vertically upward along the second folding line 122 between the second bottom panel 42 toward the side of the second top panel 32, and the sixth side panel 26 is bent laterally toward the side of the fifth side panel 25 along the second folding line 122 between the fifth side panel 25 and the fifth side panel 25 and is stacked on the second top panel 32 to form a square tube shape; wherein, the second card groove 121 is arranged on the fifth side panel 25, and when the second pressure plate 120 is folded into a tubular structure, the second card groove 121 is arranged toward the third limiting portion 13 and is connected to the square tube-shaped hollow portion of the second limiting portion 12.

[0050] Then, if Figure 1 and Figure 4 As shown, the third limiting portion 13 includes a third pressing plate 130 made of corrugated paper, a third folding structure formed on the third pressing plate 130, and a vertical limiting structure formed on the third pressing plate 130. The third pressing plate 130 cooperates with the third folding structure to fold into a tubular structure. The vertical limiting structure is used to adapt to the corresponding end contour of the middle part of the frame sub-assembly, and facilitates the third card slot 131 to be vertically mounted from top to bottom on the outer side of the middle part of the frame sub-assembly, thereby preventing the frame sub-assembly from moving in the vertical direction and causing collision damage.

[0051] The third pressure plate 130 is a rectangular sheet structure. The lower end of the tubular structure after the third pressure plate 130 is folded is fixedly connected to the bottom support plate 10. At the same time, the left and right ends of the tubular structure are respectively abutted against the third enclosure 103 and the fourth enclosure 104 to increase the bearing capacity of the entire packaging base and improve the firmness of the packaging.

[0052] When the third limiting portion 13 is assembled, the seventh side panel 27 and the eighth side panel 28 are respectively bent vertically downward along the third folding line 132 on the corresponding side of the third top panel 33, the fourth bottom panel 44 is bent laterally along the third folding line 132 between the fourth bottom panel 44 and the eighth side panel 28 toward the side of the seventh side panel 27, and the third bottom panel 43 is bent laterally along the third folding line 132 between the third bottom panel 43 and the seventh side panel 27 toward the side of the eighth side panel 28 and is stacked on the outer side of the fourth bottom panel 44 to form a square tube shape; The third card slot 131 includes a third strip-shaped slot 131a which is connected to the seventh side plate 27 and the third bottom plate 43, and a fourth strip-shaped slot 131b which is connected to the eighth side plate 28 and the fourth bottom plate 44. When the third pressing plate 130 is folded into a tubular structure, the third strip-shaped slot 131a and the fourth strip-shaped slot 131b are combined to form a third card slot 131 which passes through the third limiting portion 13 in the longitudinal direction and opens downward, and the third card slot 131 is sealed at the top in the vertical direction.

[0053] Among them, since the pressing plate itself has a certain thickness, it is easy for the creases to be not in a straight line when folded, which affects the quality of bending and forming. Therefore, a bending auxiliary part 5 is formed on the pressing plate of the second limiting part 12 and the third limiting part 13. The bending auxiliary part 5 includes a plurality of strip holes 51 arranged on the folding line between the side plate and the bottom plate. Each strip hole 51 is opened at equal intervals along the length direction of the corresponding folding line to reduce the difficulty of bending and forming.

[0054] During packaging, after folding the first pressing plate 110 and the second pressing plate 120 through the first folding line 112 and the second folding line 122, the first limiting part 11 and the second limiting part 12 are installed in the supporting cover part 1 and fixed. Since there is an installation angle between the vertical tube (not marked) and the front support tube (not marked) in the frame sub-assembly, one end of the front support tube of the frame sub-assembly is first extended into the square tubular hollow part of the second limiting part 12 through the second clamping groove 121, and then one end of the vertical tube of the frame sub-assembly is obliquely inserted into the first clamping groove 111. At this time, the frame sub-assembly is in a horizontal position, and then the third limiting part 13 formed by folding the third pressing plate 130 through the third folding line 132 is placed in the middle position of the front support tube, and the third clamping groove 131 is vertically sleeved on the outer side of the middle part of the front support tube from top to bottom, and then the third limiting part 13 is fixedly connected to the supporting cover part 1 by gluing or nailing to complete the packaging and fixation of the frame sub-assembly.

[0055] It should be noted that if Figure 6 As shown, if two limiting units need to be set on the cover part 1, it is only necessary to install the two limiting units in a mirror image, that is, place the two second limiting parts 12 back to back, and the two first limiting parts 11 and the third limiting parts 13 are respectively set in a mirror image.

[0056] In addition, if Figure 5 As shown, since the third limiting portion 13 is located in the middle of the frame sub-assembly and is in a top-down sleeve form, combined with the length of the packing size, in order to avoid the packaging deformation affected by the length and ensure the packaging efficiency, the third limiting portion 13 can also be disassembled into at least two sections for easy use. The setting and assembly of each section are the same as the overall use of the third limiting portion 13, and will not be repeated here.
