Description

Technical Field

[0001] This invention relates to a combined logistics device for a front subframe and its packaging method, belonging to the field of packaging box technology. Background Technology

[0002] In today's rapidly developing and increasingly specialized automotive industry, auto parts are typically manufactured by auto parts manufacturers located in different regions according to design drawings, and then transported individually to the vehicle manufacturer's final assembly department for unified assembly. During the manufacturing, storage, transportation, and assembly processes of auto parts, the scientific selection of packaging boxes can help minimize transportation losses, reduce transportation costs, and improve transport efficiency.

[0003] The front subframe of an automobile is developed based on the modularization and platformization of the vehicle chassis. It can withstand the vibration loads of the engine mounts and various impacts from the road surface, reducing vibrations and noise from the road and engine, and ensuring driving comfort and stability. However, due to the irregular shape of the front subframe, the utilization rate of packaging space during storage and transportation is low, which is detrimental to improving packaging quality and logistics efficiency. Currently, front subframes are typically stored or transported in wooden or cardboard boxes, filled with flexible materials such as sponge and foam to prevent damage. This packaging method has many drawbacks, including poor shock absorption and insecure fixation. Furthermore, the fixed size of the boxes limits flexibility, further hindering improvements in packaging quality and logistics efficiency. Summary of the Invention

[0018] Preferably, the first cavity further includes a first upper plate groove and / or a protrusion receiving groove that communicates with the body groove;

[0019] The first upper plate groove is formed by an inward recess from the top surface of the body, which is adapted to the bottom surface and / or side surface of the upper connecting plate of the front subframe.

[0020] The protruding part groove is formed by the inward recess of the second support platform and is adapted to the protruding part of the front subframe.

[0025] When the second pad is connected to the first recessed platform, the top surface of the second pad is at the same height as the top surface of the main body.

[0026] To achieve the above objectives, the present invention also provides a method for packaging a combined logistics equipment for a front subframe, comprising the following steps:

[0027] The front subframe is housed in the first cavity of the appliance body. The first cavity includes a body groove formed by an inward recess from the top of the body. The body groove is adapted to the bottom surface of the frame body of the front subframe, and the frame body is supported by the body groove.

[0028] A first pad is installed on the main body of the appliance. A first support platform is formed by an inward recess on the top surface of the main body. The first pad includes a first support column supported on the first support platform.

[0029] The other front subframe is tilted toward the second cavity housed in the main body of the appliance. The second cavity includes a second support platform formed by an inward recess from the top surface of the main body and a rear lower plate support platform formed by an outward protrusion from the side of the first support column. The second support platform is higher than the groove of the main body and is adapted to the top surface of the frame body. The top surface of the rear lower plate support platform is adapted to the top surface of the rear lower connecting plate of the front subframe. The frame body of the other front subframe is supported on the second support platform, and the rear lower connecting plate of the other front subframe is supported on the rear lower plate support platform.

[0030] A second pad is installed on the main body of the appliance. A first recess is formed by indentation on one side edge of the top surface of the main body, and the second pad is supported on the first recess.

[0031] Preferably, the bottom surface of the appliance body is recessed inward to form a second recess that matches the first recess, and the second recess is formed on the opposite side to the first recess.

[0033] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The logistics device of the present invention is composed of several device bodies, a first pad, and a second pad. The top surface of the device body is recessed inward to form a first recess and a cavity for accommodating the front subframe, and the bottom surface of the device body is recessed inward to form a second recess that matches the first recess. Multiple device bodies can be combined in both longitudinal and transverse directions. When combined longitudinally, the first limiting post of the lower device body can be precisely embedded in the first limiting groove of the upper device body; when two device bodies are combined transversely, the second limiting post of the rear device body can be precisely embedded in the second limiting groove of the front device body. Both combination methods can achieve limiting and fixing between adjacent device bodies. The longitudinal combination method expands the longitudinal packaging space of the logistics device of the present invention, and the transverse combination method expands the transverse packaging space of the logistics device of the present invention. Both combination methods can be used individually or simultaneously, effectively overcoming the problem of poor flexibility caused by fixed packaging box dimensions. The cavity serves to fix and limit the front subframe, including a first cavity for accommodating the front subframe in a forward direction and a second cavity for accommodating the front subframe in a backward direction. The second cavity needs to be constructed with the assistance of the first pad block. The upper connecting plates of the two front subframes are staggered and accommodating each other. Therefore, under the condition of accommodating two front subframes in the longitudinal direction at the same time, the height of the appliance body is greatly reduced, which is conducive to stacking more appliance bodies and accommodating more front subframes in the limited longitudinal packaging space.

[0051] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0052] It should be noted that in the description of this invention, the terms "front," "rear," "left," "right," "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used only for the convenience of describing the invention and do not require the invention to be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on the invention. The terms "front," "rear," "left," "right," "upper," and "lower" used in the description of this invention refer to the directions shown in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0053] This invention provides a modular logistics device for a front subframe, composed of several device bodies 1. Each device body 1 can be fitted with a first pad 4 and a second pad 5 as needed. The device body 1, the first pad 4, and the second pad 5 are all integrally molded from expanded polystyrene (EPS), resulting in a lightweight and high-strength structure. EPS is a lightweight polymer made by adding a foaming agent to polystyrene resin, simultaneously heating to soften it and generate gas, forming a rigid, closed-cell foam plastic with low water absorption, good thermal insulation, light weight, and high mechanical strength.

[0054] like Figures 7 to 9 The figures show a top perspective view, a bottom perspective view, and a front view of the front subframe in an embodiment of the present invention. The front subframe 6 has a frame body 61, which extends laterally outward to form two front lower connecting plates 62 and two rear lower connecting plates 63. The top surface of the frame body 61 has two upper connecting plates 64 that first extend longitudinally upward and then laterally outward. The top surface of the frame body 61 also has protrusions 65 that extend laterally. As can be seen from the figures, the top surface structure of the front subframe 6 is relatively complex, not only uneven but also with many longitudinal protrusions; the bottom surface of the front subframe 6 is relatively flat, which is convenient for bearing weight and stress. For ease of description, the top surface of the front subframe 6 facing upward is defined as upright placement, and the top surface of the front subframe 6 facing downward is defined as inverted placement.

[0055] like Figures 1 to 5 The figures shown are, respectively, a top perspective view, a top view, a bottom perspective view, a bottom view, and a left view of the device body in an embodiment of the present invention. The top surface 2 of the device body 1 is recessed inward to form a first recess 21 and a cavity for accommodating the front subframe 6. The bottom surface 3 of the device body 1 is recessed inward to form a second recess 31 that matches the first recess 21. More specifically, the first recess 21 is formed on the top surface 2 at the front edge of the device body 1, and the second recess 31 is formed on the bottom surface 3 at the rear edge of the device body 1.

[0056] Both the top surface 2 of the main body and the first recessed platform 21 are provided with several outwardly protruding limiting posts, wherein the limiting posts on the top surface 2 of the main body are the first limiting posts 211, and the limiting posts on the first recessed platform 21 are the second limiting posts 212. Both the bottom surface 3 of the main body and the second recessed platform 31 are provided with several inwardly recessed limiting grooves, wherein the limiting grooves on the bottom surface 3 of the main body are the first limiting grooves 311, and the limiting grooves on the second recessed platform 31 are the second limiting grooves. The first limiting posts 211 are adapted to the first limiting grooves 311, and the second limiting posts 212 are adapted to the second limiting grooves. That is, when the two appliance bodies 1 are combined longitudinally, the first limiting post 211 of the lower appliance body 1 can be inserted into the first limiting groove 311 of the upper appliance body 1; when the two appliance bodies 1 are combined laterally, the second limiting post 212 of the rear appliance body 1 can be inserted into the second limiting groove of the front appliance body 1.

[0057] Both the longitudinal and transverse combination methods described above can achieve the limiting and fixing between two adjacent device bodies 1. The first longitudinal combination method expands the longitudinal packaging space of the logistics device of the present invention, and the second transverse combination method expands the transverse packaging space of the logistics device of the present invention. The two combination methods can be used individually or simultaneously, which can effectively overcome the problem of poor flexibility caused by the fixed size of the packaging box.

[0058] As a preferred embodiment, the bottom surface 3 of the main body and the second recessed platform 31 are provided with a plurality of inwardly recessed material-reducing grooves 312, which mainly serve to save material and reduce weight. At the same time, the aforementioned first limiting post 211 is formed at the edge of the material-reducing groove 312 on the bottom surface 3 of the main body, and the aforementioned second limiting groove is formed at the edge of the material-reducing groove 312 on the second recessed platform 31. They can also work together with the first limiting post 211 and the second limiting post 212 to limit and fix two adjacent appliance bodies 1, so as to simplify the structural design and reduce manufacturing costs.

[0059] The main structure of the cavity includes a body groove 22 formed by an inward indentation from the top surface 2 of the body, a first support platform 27, and a second support platform 28. In terms of the depth of the groove surface or the support platform surface, the body groove 22 is the deepest, followed by the first support platform 27, and the second support platform 28 is the highest. The cavity includes a first cavity position for receiving the front subframe 6 facing forward and a second cavity position for receiving the front subframe 6 in reverse. The front subframe 6 received in the second cavity position is located above the front subframe 6 received in the first cavity position. The two front subframes 6 are distributed facing each other. Specifically, in this embodiment, the front lower connecting plate 62 of the front subframe 6 in the first cavity position faces forward, and the front lower connecting plate 62 of the front subframe 6 in the second cavity position faces backward.

[0060] The first cavity includes a body groove 22 and a first front lower plate groove 23, a first upper plate groove 24, a rear lower plate groove 25, and a protrusion receiving groove 26 connected thereto. The first front lower plate groove 23, the first upper plate groove 24, and the rear lower plate groove 25 are all formed by inward indentation from the top surface 2 of the body, and the protrusion receiving groove 26 is formed by inward indentation from the second support platform 28. Among them, the body-shaped groove 22 is adapted to the bottom surface of the frame body 61 to receive and support the bottom surface of the frame body 61; the first front lower plate groove 23 is adapted to the bottom surface of the front lower connecting plate 62 to receive and support the bottom surface of the front lower connecting plate 62; the first upper plate groove 24 is adapted to the bottom surface and outer side surface of the upper connecting plate 64 to receive and support the bottom surface and outer side surface of the upper connecting plate 64; the rear lower plate groove 25 is adapted to the bottom surface of the rear lower connecting plate 63 to receive and support the bottom surface of the rear lower connecting plate 63; the protrusion receiving groove 26 is adapted to the protrusion 65, and the protrusion 65 is received in the protrusion receiving groove 26 with clearance to avoid damage due to pressure.

[0061] In addition to the aforementioned main structure, the second type of cavity also requires the cooperation of the first pad 4 and the second pad 5 to achieve its purpose. For example... Figure 6 The image shown is a top perspective view of the appliance body with the first and second pads installed. The top surface of the appliance body has a recessed cavity at its edge, forming tenons 271 of the same depth as the first support platform 27 and interconnected with each other. There are two first support platforms 27 and two tenons 271, symmetrically distributed from left to right. The first recessed platform 21 has three pad mounting slots 213 formed by its inward recess.

[0062] like Figure 15 The image shown is a top perspective view of the first pad block in an embodiment of the present invention. The first pad block 4 includes a first support column 41. The outer side of the first support column 41 protrudes outward to form a tenon 42 that matches the mortise groove 271. The inner side of the first support column 41 protrudes outward at a lower position to form a rear lower plate support platform 43. The first pad block 4 adopts a mortise and tenon structure and is detachably connected to the appliance body 1. That is, the first pad block 4 is embedded into the mortise groove 271 of the appliance body 1 via its tenon 42. At this time, the first support column 41 is supported by the first support platform 27, and the pressure transmitted to the first support column 41 is supported by the first support platform 27. The top surface of the first pad block 4 is at the same height as the top surface 2 of the appliance body.

[0063] After the first pad 4 is installed, the second cavity includes a second support platform 28, a second front lower plate groove 281, a second upper plate groove 282, and a rear lower plate support platform 43. The second front lower plate groove 281 and the second upper plate groove 282 are also formed by inward indentation from the top surface 2 of the main body. Among them, the second support platform 28 is adapted to the top surface of the frame body 61 to accommodate and support the top surface of the frame body 61. The second front lower plate groove 281 is adapted to the top surface of the front lower connecting plate 62 to accommodate and support the top surface of the front lower connecting plate 62. The second upper plate groove 282 is adapted to the top surface and inner side surface of the upper connecting plate 64 to accommodate and support the top surface and inner side surface of the upper connecting plate 64; the deepest part of the second upper plate groove 282 is provided with a clearance groove 283 to avoid the end of the upper connecting plate 64 from being damaged by pressure. The top surface of the rear lower plate support platform 43 is adapted to the top surface of the rear lower connecting plate 63 to accommodate and support the top surface of the rear lower connecting plate 63.

[0064] In the first type of cavity, the front subframe 6 is in a forward-facing storage position with its upper connecting plate 64 facing upward; in the second type of cavity, the front subframe 6 is in a backward-facing storage position with its upper connecting plate 64 facing downward. That is, the upper connecting plates 64 of the two front subframes 6 are staggered and opposite each other. Therefore, under the condition of simultaneously storing two front subframes 6 in the longitudinal direction, the layer height of the appliance body 1 is greatly compressed, so as to facilitate the stacking of more appliance bodies 1 and the storage of more front subframes 6 in the limited longitudinal packaging space.

[0065] like Figure 16 The image shown is a perspective view of the bottom surface of the second pad block in an embodiment of the present invention. The second pad block 5 includes a pad block body 51. The bottom surface of the pad block body 51 protrudes outward to form a pad block mounting post 52 that is adapted to the pad block mounting groove 213. When the second pad block 5 is detachably installed on the first recessed platform 21, the pad block mounting post 52 of the second pad block 5 is precisely embedded in the pad block mounting groove 213, realizing the function of mutual limiting and fixing. At this time, the top surface of the second pad block 5 is at the same height as the top surface 2 of the body. When multiple appliance bodies 1 are combined in a horizontal direction, the second pad block 5 is installed on the first recessed platform 21 of the foremost appliance body 1; when multiple appliance bodies 1 are combined in a longitudinal direction, the second pad block 5 of the lower appliance body 1 supports the bottom surface 3 of the upper appliance body 1.

[0066] This invention provides a method for packaging a combined logistics device for a front subframe. This method is based on the aforementioned logistics device and includes the following steps:

[0067] Step one: Place the front subframe 6 face up into the first cavity of the appliance body 1. For example... Figure 10The image shown is a top perspective view of step one of the process of accommodating the front subframe of the appliance body. The first cavity includes a body groove 22 and connected to it a first front lower plate groove 23, a first upper plate groove 24, a rear lower plate groove 25, and a protrusion receiving groove 26. The first front lower plate groove 23, the first upper plate groove 24, and the rear lower plate groove 25 are all formed by inward indentation from the top surface 2 of the body, and the protrusion receiving groove 26 is formed by inward indentation from the second support platform 28. Among them, the body-shaped groove 22 is adapted to the bottom surface of the frame body 61 to receive and support the bottom surface of the frame body 61; the first front lower plate groove 23 is adapted to the bottom surface of the front lower connecting plate 62 to receive and support the bottom surface of the front lower connecting plate 62; the first upper plate groove 24 is adapted to the bottom surface and outer side surface of the upper connecting plate 64 to receive and support the bottom surface and outer side surface of the upper connecting plate 64; the rear lower plate groove 25 is adapted to the bottom surface of the rear lower connecting plate 63 to receive and support the bottom surface of the rear lower connecting plate 63; the protrusion receiving groove 26 is adapted to the protrusion 65, and the protrusion 65 is received in the protrusion receiving groove 26 with clearance to avoid damage due to pressure.

[0068] Step two, install the first pad 4 on the appliance body 1. (For example...) Figure 11 The image shown is a top perspective view of step two of accommodating the front subframe of the appliance body. A first support platform 27 and a mortise 271 of equal depth and interconnection are formed at the inwardly recessed edge of the cavity on the top surface 2 of the body. The first pad 4 includes a first support post 41. A tenon 42, matching the mortise 271, protrudes outward from the outer side of the first support post 41. A rear lower plate support platform 43 protrudes outward from the lower inner side of the first support post 41. The first pad 4 is inserted into the mortise 271 of the appliance body 1 via its tenon 42. The first support post 41 is supported by the first support platform 27, and the pressure transmitted to the first support post 41 is supported by the first support platform 27. The top surface of the first pad 4 is at the same height as the top surface 2 of the body.

[0069] Step three, tilt the other front subframe 6 towards the second cavity housed in the main body of the device 1. (As follows) Figure 12 The image shown is a top perspective view of step three, where the appliance body houses the front subframe. The second cavity includes a second support platform 28, a second front lower plate groove 281, a second upper plate groove 282, and a rear lower plate support platform 43. The second support platform 28 is fitted to the top surface of the frame body 61 to house and support the top surface of the frame body 61. The second front lower plate groove 281 is fitted to the top surface of the front lower connecting plate 62 to house and support the top surface of the front lower connecting plate 62. The second upper plate groove 282 is fitted to the top and inner surfaces of the upper connecting plate 64 to house and support the top and inner surfaces of the upper connecting plate 64; the deepest part of the second upper plate groove 282 has a clearance groove 283 to allow clearance at the end of the upper connecting plate 64, preventing damage from pressure. The top surface of the rear lower plate support platform 43 is fitted to the top surface of the rear lower connecting plate 63 to house and support the top surface of the rear lower connecting plate 63.

[0070] Step four: Install the second pad 5 onto the appliance body 1. (For example...) Figure 13 The image shown is a top perspective view of step four of accommodating the front subframe of the appliance body. A first recessed platform 21 is formed inwardly at one edge of the top surface 2 of the body, and three pad mounting slots 213 are formed within the first recessed platform 21. The second pad 5 includes a pad body 51, and the bottom surface of the pad body 51 protrudes outwardly to form a pad mounting post 52 that matches the pad mounting slot 213. The second pad 5 is detachably connected to the pad mounting slot 213 of the first recessed platform 21 via its pad mounting post 52. The second pad 5 is supported by the first recessed platform 21, at which point the top surface of the second pad 5 is at the same height as the top surface 2 of the body.

[0071] Step 5: Combine the two appliance bodies 1 horizontally. For example... Figure 14 The image shown is a top perspective view of step five of accommodating the front subframe of the appliance body. The bottom surface 3 of the appliance body 1 is recessed inward to form a second recess 31 that matches the first recess 21. The second recess 31 is formed on the side opposite to the first recess 21. The second recess 31 of the aforementioned appliance body 1 is pressed onto the first recess 21 of another appliance body 1.

[0072] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
