Description

Technical Field

[0001] This application relates to the field of vehicle export packaging technology, and in particular to a packaging structure suitable for front suspension engines. Background Technology

[0002] In recent years, an increasing number of customers in car-importing countries have requested that cars be imported in the form of knocked-down kits. This means that parts are manufactured in the parts-producing countries and exported to the importing countries as fully knocked-down or semi-knocked-down kits. The parts are then assembled into complete assemblies or whole vehicles at local assembly plants in the market countries and released after passing inspection. This is a form of global cooperation.

[0003] For example, hybrid vehicles are exported in a modular form, where the front suspension assembly is composed of a front subframe, engine, electric drive unit, and mounting brackets. The engine and electric drive unit are rigidly connected (bolted), and the engine and electric drive unit are connected to the front subframe by three mounting brackets. Due to the rubber bushings inside the mounting brackets, there is a relative amount of movement between the engine and electric drive unit and the front subframe.

[0004] The engine and electric drive unit are combined with the front subframe as a whole, which makes the export packaging design difficult. It is impossible to properly fix the three assemblies. Due to the amount of movement between the assemblies (relative movement and insufficient constraint), the Z-axis support point often fails. During transportation, the parts are damaged due to bumps and shaking. Summary of the Invention

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] This application provides a packaging structure suitable for front suspension engines, which can solve the problem in related technologies that the export packaging design of front suspension assemblies is difficult, making it impossible to properly fix the three assemblies, and causing damage to parts due to bumps and shaking during transportation.

[0023] See Figures 1 to 9As shown, this application embodiment provides a packaging structure suitable for front suspension engines, the packaging structure 100 including: The packaging frame body includes a bottom rigid frame 110, and rigid fences 120 are fixedly connected to the top of the bottom rigid frame 110. The rigid fences 120 and the bottom rigid frame 110 are connected to each other to form a rectangular frame structure with an open top. The bottom rigid frame 110 is used to support the front suspension engine assembly 200, and the rigid fences 120 are used to surround the outer perimeter of the front suspension engine assembly 200, so that the front suspension engine assembly 200 is packaged in the rectangular frame structure formed by the interconnection of the rigid fences 120 and the bottom rigid frame 110.

[0024] The mounting and positioning mechanism includes a vertical support mechanism 130 and a horizontal limiting mechanism 140 fixed to the top of the bottom rigid frame 110 for positioning and supporting the front subframe 210, and a support beam 126 connected to the rigid enclosure 120 for fixing and supporting the powertrain's upper suspension. The vertical support mechanism 130 and the horizontal limiting mechanism 140 are used to support and position the front subframe 210 of the front suspension engine assembly 200 in the vertical and horizontal directions. The support beam 126 on the rigid enclosure 120 positions and supports the engine 220 and electric drive unit 230 of the front suspension engine assembly 200 via the powertrain's upper suspension.

[0025] The packaging structure for the front-suspension engine in this embodiment utilizes a packaging frame body as the protective outer skeleton for the front-suspension engine assembly 200. The bottom rigid frame 110 of the packaging frame body supports the front-suspension engine assembly 200, and a rigid fence 120 is used to surround the outer perimeter of the front-suspension engine assembly 200, so that the front-suspension engine assembly 200 is packaged within a rectangular frame structure formed by the interconnection of the rigid fence 120 and the bottom rigid frame 110. The front-suspension engine assembly 200 is packaged and fixed inside the packaging frame body, so that the front-suspension engine assembly is protected from all directions by the packaging frame body during transportation.

[0026] To reduce the deformation, cracking, and other damage to the front suspension engine assembly 200 caused by impact and shaking during transportation, this embodiment of the application uses a vertical support mechanism 130 and a horizontal limiting mechanism 140 at the top of the bottom rigid frame 110 to position and support the front subframe, and a support beam 126 for fixing the powertrain suspension on the rigid fence 120. Thus, the front suspension engine assembly 200 is fixed to the packaging frame body, so that the suspension is fully stressed, the bottom support force is reduced, and the impact damage to the engine and electric drive unit is reduced.

[0027] In some alternative embodiments: see Figure 5 and Figure 6As shown in the figure, this application embodiment provides a packaging structure suitable for front-suspension engines. The bottom rigid frame 110 of the packaging structure 100 includes multiple lower crossbeams 112 and multiple lower longitudinal beams 111, which are perpendicularly connected to each other to form a grid-like rectangular frame. The bottom of the bottom rigid frame 110 is provided with lower support legs 114 that vertically support the bottom rigid frame 110, and forklift insertion holes 113 fixed to the bottom of the bottom rigid frame 110.

[0028] The bottom rigid frame 110 of this embodiment includes multiple lower crossbeams 112 and multiple lower longitudinal beams 111 connected perpendicularly to each other to form a grid-like rectangular frame. The multiple lower crossbeams 112 and multiple lower longitudinal beams 111 are preferably, but not limited to, made of steel profiles or aluminum alloy profiles. The bottom of the bottom rigid frame 110 is provided with lower support legs 114 that support the bottom rigid frame 110 vertically. After the lower support legs 114 support the bottom rigid frame 110 to a set height, it is convenient for the forklift forks to be inserted into the forklift insertion hole 113 for overall handling and packaging structure.

[0029] In some alternative embodiments: see Figure 5 and Figure 6 As shown, this application embodiment provides a packaging structure suitable for front suspension engines. The rigid enclosure 120 of the packaging structure 100 includes corner posts 121 fixed to the four corners of the top of the bottom rigid frame 110, as well as two parallel and spaced upper horizontal beams 122 and two parallel and spaced upper vertical beams 123. The two upper horizontal beams 122 and the two upper vertical beams 123 are connected end to end to form a rectangular frame and fixed above the corner posts 121.

[0030] In this embodiment, the rigid fence 120 is fixed to the top of the bottom rigid frame 110, and the projection of the rigid fence 120 onto the bottom rigid frame 110 coincides with the edge contour of the bottom rigid frame 110. The rigid fence 120 forms a three-dimensional frame fence through two mutually perpendicularly connected corner posts 121, upper crossbeams 122, and upper longitudinal beams 123. This ensures that the front suspension engine assembly 200 located within the rigid fence 120 is not subject to external impact or damage during handling, storage, or transportation.

[0031] In some alternative embodiments: see Figure 5 and Figure 6 As shown, this application embodiment provides a packaging structure suitable for front suspension engines. The rigid fence 120 of the packaging structure 100 also includes a first column 124 connected between the upper crossbeam 122 and the bottom rigid frame 110, and two parallel and spaced second columns 125 respectively connected between the upper longitudinal beam 123 and the bottom rigid frame 110. The two ends of the supporting crossbeam 126 are respectively connected to the two symmetrical second columns 125.

[0032] In this embodiment, the rigid fence 120 has a first column 124 connecting the upper crossbeam 122 and the bottom rigid frame 110, and two parallel and spaced second columns 125 connecting the upper longitudinal beam 123 and the bottom rigid frame 110. The first column 124 and the second column 125 enhance the vertical support rigidity of the rigid fence 120, enabling the packaging structure to accommodate multi-layer stacking during storage or transportation. The second column 125 also provides fixed support for the support beam 126, providing positioning support for the front suspension engine assembly 200, which is mounted and fixed to the support beam 126 via the powertrain.

[0033] In some alternative embodiments: see Figure 5 and Figure 6 As shown in the figure, this application embodiment provides a packaging structure suitable for front suspension engines. The packaging structure 100 has multiple lower support legs 114, which are respectively located at the four bottom corners of the bottom rigid frame 110. The lower support legs 114 include interconnected transverse support blocks and longitudinal support blocks, which are interconnected to form an "L" shape. The four top corners of the rigid fence 120 are respectively provided with upwardly protruding "L" shaped corner plates 127.

[0034] The lower support leg 114 in this embodiment includes a transverse support block and a longitudinal support block connected to each other. The transverse support block is located at both ends of the lower crossbeam 112, and the longitudinal support block is located at both ends of the lower longitudinal beam 111. The transverse support block and the longitudinal support block are connected to each other to form an "L"-shaped structure to vertically support the bottom rigid frame 110. At the top four corners of the rigid fence 120, there are upwardly protruding "L"-shaped corner plates 127. These "L"-shaped corner plates 127 are used to cooperate with the lower support leg 114 to facilitate the mutual positioning of the two lower packaging structures.

[0035] In some alternative embodiments: see Figures 1 to 9 As shown, this application embodiment provides a packaging structure suitable for a front suspension engine. The vertical support mechanism 130 of the packaging structure 100 includes a front support frame 131 that vertically supports the front crossbeam of the front subframe, and a rear support frame 132 that vertically supports the rear crossbeam of the front subframe. The horizontal limiting mechanism 140 includes a first positioning post 141 that limits the front subframe longitudinal beam to the left and right, and a second positioning post 142 that limits the front crossbeam and the rear crossbeam of the front subframe longitudinal beam to the front and rear.

[0036] The vertical support mechanism 130 of this application embodiment is provided with a front support frame 131 that vertically supports the front crossbeam of the front subframe and a rear support frame 132 that vertically supports the rear crossbeam of the front subframe. The front suspension engine assembly 200 sits on the front support frame 131 and the rear support frame 132 via the front subframe 210, thereby positioning and supporting the front suspension engine assembly 200 in the height direction within the packaging structure, preventing the front suspension engine assembly 200 from bouncing up and down within the packaging structure during transportation.

[0037] The horizontal limiting mechanism 140 is provided with a first positioning post 141 that limits the left and right sides of the front subframe longitudinal beam, and a second positioning post 142 that limits the front crossbeam and rear crossbeam of the front subframe longitudinal beam. The front suspension engine assembly 200 cooperates with the first positioning post 141 and the second positioning post 142 through the front subframe 210, thereby positioning the front suspension engine assembly 200 horizontally within the packaging structure, preventing the front suspension engine assembly 200 from swaying left and right or back and forth within the packaging structure during transportation.

[0038] In some alternative embodiments: see Figures 7 to 9 As shown, this application embodiment provides a packaging structure suitable for front suspension engines. The front support frame 131 of the packaging structure 100 includes an upper support beam extending along the length direction of the front crossbeam of the front subframe, and a first lower support fixed to the top of the bottom rigid frame 110 and vertically supporting the upper support beam. Positioning blocks for clamping the front crossbeam of the front subframe are provided on both sides of the upper support beam.

[0039] In this embodiment, the upper support crossbeam extends along the length of the front crossbeam of the front subframe and is used to abut against the bottom surface of the front crossbeam of the front subframe to vertically support the front crossbeam of the front subframe. A first lower support is used to vertically support the upper support crossbeam so that the upper support crossbeam maintains a set height at the top of the bottom rigid frame 110. Positioning blocks for clamping the front crossbeam of the front subframe are provided on both sides of the upper support crossbeam; these positioning blocks are used to position the front crossbeam of the front subframe in the longitudinal direction.

[0040] In some alternative embodiments: see Figures 7 to 9 As shown, this application embodiment provides a packaging structure suitable for front suspension engines. The rear support frame 132 of the packaging structure 100 includes a plurality of second lower supports arranged sequentially at intervals along the length direction of the rear crossbeam of the front subframe. The top of the second lower support is provided with an upper support pad that fits against the bottom surface of the rear crossbeam of the front subframe. The upper support pad and the second lower support are used to vertically support the rear crossbeam of the front subframe at a set height.

[0041] The rear support frame 132 of this application embodiment includes a plurality of second lower supports arranged at intervals along the length direction of the rear crossbeam of the front subframe. Each second lower support has an upper support pad at its top that fits against the bottom surface of the rear crossbeam of the front subframe. The second lower supports keep the upper support pad at a set height on the top of the bottom rigid frame 110. The rear support frame 132 and the front support frame 131 cooperate with each other to vertically support the front subframe 210.

[0042] In some alternative embodiments: see Figures 1 to 4 and Figure 9 As shown in the illustration, this application provides a packaging structure suitable for a front-suspension engine. The packaging structure 100 further includes a front-suspension engine assembly 200 located within the packaging frame body. The front-suspension engine assembly 200 includes an engine 220 and an electric drive unit 230 connected to each other. The engine 220 and the electric drive unit 230 are respectively connected to a front subframe 210 via multiple lower mounts. The front subframe 210 is fixed to a vertical support mechanism 130 and a horizontal limiting mechanism 140.

[0043] The powertrain upper mounts include a left upper mount 240 and a right upper mount 250. The engine 220 and the electric drive unit 230 are fixed to the support beam 126 via the left upper mount 240 and the right upper mount 250, respectively. Mounting holes for connecting the left upper mount 240 and the right upper mount 250 are provided on the support beam 126. The rigid fence 120 and the bottom rigid frame 110 are both fixedly connected by welding steel profiles.

[0044] Working principle This application provides a packaging structure suitable for front-suspension engines. The packaging structure 100 for front-suspension engines of this application is provided with a packaging frame body, which includes a bottom rigid frame 110. Rigid fences 120 are fixedly connected to the top of the bottom rigid frame 110.
