Description

Technical Field

[0001] The invention relates to a logistics device for a dashboard crossbeam and a packaging method thereof, belonging to the technical field of packaging boxes. Background Art

[0002] In today's rapidly evolving automotive industry, where specialized labor is becoming increasingly specialized, auto parts are typically manufactured by dispersed auto parts manufacturers based on design drawings. These parts are then shipped to the final assembly department of the automaker for centralized assembly. Choosing the right packaging for auto parts during factory delivery, storage, transportation, and assembly can help minimize transportation losses, reduce transportation costs, and improve efficiency.

[0003] The cross car beam (CB) is a crucial component of passenger car interiors, connecting the dash, left and right side panels, and floor. It supports components such as airbags and electrical appliances, and positions the instrument panel. Its quality directly determines the assembly stability of the instrument panel. The CB, consisting of a crossbeam, a crossbeam mounting plate, an assembly mounting bracket, a navigation system bracket, a dash bracket, and a glove box bracket, is irregular in shape, and non-load-bearing components are susceptible to deformation under pressure, creating challenges in packaging and transportation. Currently, CBs are typically stored or transported in wooden or paper boxes, filled with flexible materials such as sponge and foam to protect them from damage. This packaging method not only suffers from poor shock absorption, insecure fixation, and contamination, but also inefficient packaging space utilization, hindering packaging quality and improving logistics efficiency.

[0038] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0039] It should be noted that, in the description of the present invention, the terms "front," "rear," "left," "right," "up," "down," "inside," and "outside" and the like, indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. These are intended solely to facilitate the description of the present invention and do not require that the present invention be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. The terms "front," "rear," "left," "right," "up," and "down" used in the description of the present invention refer to directions in the accompanying drawings, and the terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0040] A specific embodiment of the present invention provides a logistics device for use with a dashboard crossbeam. The device is composed of several device bodies stacked longitudinally. The device bodies are integrally molded from expanded polystyrene (EPS). EPS is a lightweight polymer. It is formed by adding a foaming agent to polystyrene resin and heating it to soften it, generating gas. This creates a rigid, closed-cell foam plastic with low water absorption, excellent thermal insulation, light weight, and high mechanical strength.

[0041] like Figure 7 、 8The figures show the front and back structures of an instrument panel cross member according to an embodiment of the present invention. The instrument panel cross member 3 primarily comprises a cross member 31. Assembly mounting brackets 32 are mounted on both ends of the cross member 31, facing the front. Cross member mounting plates 311 are mounted on both ends of the cross member 31, facing the back. From left to right, the front of the cross member 31 features an instrument panel bracket 33, a dash bracket 35, and a glove box bracket 37. A navigation bracket 34 is positioned downward in the center of the cross member 31. To the left of the navigation bracket 34, an instrument panel mounting plate 341 is positioned, cooperating with the instrument panel bracket 33. A central bracket 36 is positioned on the back of the center of the cross member 31. As can be seen from the figures, the overall structure of the instrument panel cross member 3 is relatively loose, with numerous prominent protruding components along the radial direction of the cross member 31, including the cross member mounting plates 311, assembly mounting brackets 32, navigation bracket 34, dash bracket 35, and glove box bracket 37. When multiple instrument panel cross members 3 are packaged together, they interfere with each other, resulting in low packaging space utilization. Among them, the crossbeam 31 is the main load-bearing structure of the dashboard crossbeam 3, the assembly mounting bracket 32, the navigation bracket 34, and the glove box bracket 37 can be subjected to positive force, and the crossbeam mounting plate 311 can be subjected to axial force. The above structure cannot withstand force in other directions, otherwise it may cause deformation and damage.

[0042] Based on the above structural features of the instrument panel cross beam 3, the logistics equipment of the present invention has been designed and improved in a targeted manner. Figure 1-6 The figures shown are, respectively, a top perspective view, a top view, a bottom perspective view, a bottom view, a front view, and a left side view of the device body according to an embodiment of the present invention. The top surface 1 of the device body is recessed inward to form a cavity, within which are located several cavity assemblies for accommodating the instrument panel crossbeam 3. These assemblies include first and second cavity assemblies alternately arranged horizontally, with the second cavity assemblies being taller than the first. The significance of this design lies in the fact that the device body can accommodate two layers of instrument panel crossbeams 3, namely, the first cavity assemblies accommodate the lower instrument panel crossbeam 3, and the second cavity assemblies accommodate the upper instrument panel crossbeam 3.

[0043] At the same time, in order to eliminate the radial interference between the upper and lower instrument panel cross beams 3, the lower instrument panel cross beam 3 received by the first cavity assembly faces upward. Figure 7 In the posture shown, the upper instrument panel cross beam 3 received by the second cavity assembly faces downwards. Figure 8 The instrument panel cross member 3 is positioned in the same position as shown, and the two are axially offset from each other. The significance of this design lies in: first, the cross member 31, assembly mounting bracket 32, and navigation bracket 34 jointly support the weight of the instrument panel cross member 3, ensuring balanced force; second, it ensures that the front cowl bracket 35 and glove box bracket 37, which are significantly protruding radially from the upper and lower instrument panel cross member 3, are both accommodated within the cavity without occupying additional longitudinal space and avoiding interference.

[0044] More specifically, the first cavity assembly includes a first crossbeam support block 11, a first assembly mounting bracket support groove 12, a first instrument panel bracket groove 13, a first navigation bracket support block 14, a first front panel bracket groove 15, and a first central bracket groove 16; the second cavity assembly includes a second crossbeam support block 111, a second assembly mounting bracket support groove 121, a second instrument panel bracket groove 131, a second navigation bracket support block 141, a second front panel bracket groove 151, and a second glove box bracket support slope 17.

[0045] The first crossbeam support block 11, the first assembly mounting bracket support groove 12, and the first navigation bracket support block 14 respectively support the crossbeam 31, the assembly mounting bracket 32, and the navigation bracket 34 of the lower instrument panel crossbeam 3; the second crossbeam support block 111, the second assembly mounting bracket support groove 121, the second navigation bracket support block 141, and the second glove box bracket support slope 17 respectively support the crossbeam 31, the assembly mounting bracket 32, the navigation bracket 34, and the glove box bracket 37 of the upper instrument panel crossbeam 3. The above are all load-bearing structures of the device body, among which the first crossbeam support block 11 and the second crossbeam support block 111 are formed by protruding outward from the bottom surface of the cavity, and their top surfaces are provided with card grooves adapted to the crossbeam 31, and the top surface of the second crossbeam support block 111 is higher than the top surface of the first crossbeam support block 11; the first navigation bracket support block 14 and the second navigation bracket support block 141 are formed by protruding outward from the bottom surface of the cavity, and their top surfaces are inclined surfaces adapted to the bottom surface shape of the navigation bracket 34 in the storage posture, which play a role in balancing the force, and the top surface of the second navigation bracket support block 141 is higher than the top surface of the first navigation bracket support block 14; the second glove box bracket support inclined surface 17 is formed by protruding outward from the bottom surface of the cavity, and its top surface is adapted to the bottom surface shape of the glove box bracket 37 of the upper instrument panel crossbeam 3 in the storage posture.

[0046] The first instrument panel bracket receptacle 13, the first front panel bracket receptacle 15, and the first center bracket receptacle 16 accommodate the instrument panel bracket 33, the front panel bracket 35, and the center bracket 36 of the lower instrument panel cross member 3, while the second instrument panel bracket receptacle 131 and the second front panel bracket receptacle 151 accommodate the instrument panel bracket 33 and the front panel bracket 35 of the upper instrument panel cross member 3, respectively. All of the above constitute the storage structure of the device body. The first instrument panel bracket receptacle 13, the second instrument panel bracket receptacle 131, the first front panel bracket receptacle 15, and the second front panel bracket receptacle 151 are all formed by recessing inward from the side surfaces of the receptacle; the first center bracket receptacle 16 is formed by recessing inward from the bottom surface of the receptacle.

[0047] Preferably, the first assembly mounting bracket support groove 12 is recessed inward to form a space-avoiding groove adapted to the crossbar mounting plate 311 of the instrument panel crossbar 3, for accommodating the crossbar mounting plate 311 that protrudes significantly outward on the back side of the lower instrument panel crossbar 3 in a space-avoiding manner to avoid damage caused by pressure.

[0048] Preferably, the top surface 1 of the body is recessed inward to form a support transverse surface 18, and the bottom surface 2 of the device body is recessed inward to form a pressing transverse surface 21 that matches the support transverse surface 18. Specifically, the pressing transverse surface 21 and the support transverse surface 18 are positioned and sized identically, and the depth of the support transverse surface 18 relative to the top surface 1 is the same as the depth of the pressing transverse surface 21 relative to the bottom surface 2. This ensures that when multiple device bodies are stacked, the protrusion on the bottom of the upper device body fits neatly into the groove on the top of the lower device body. Specifically, the pressing transverse surface 21 of the upper device body is supported on the support transverse surface 18 of the lower device body, and the bottom surface 2 of the upper device body is supported on the top surface 1 of the lower device body, thereby limiting the lateral movement of adjacent device bodies and preventing overturning when stacked. Compared to the conventional limiting post / limiting groove method, this limiting method has a larger contact area and is therefore more advantageous in limiting effectiveness. Under this structural design, the cavity is formed by being recessed inward from the supporting transverse surface 18 .

[0049] Preferably, a pressing side surface 22 is formed between the pressing horizontal surface 21 and the body bottom surface 2. This pressing side surface 22 has an inwardly recessed side groove 221. When adjacent appliance bodies are stacked or separated, internal air can be discharged through the side groove 221, thereby preventing manipulation difficulties caused by negative pressure. The body bottom surface 2 is also recessed to form a through hole 23 extending through the bottom surface of the cavity, which also serves the same purpose and helps reduce weight and save materials.

[0050] The specific embodiment of the present invention further provides a packaging method for an instrument panel cross member, wherein the method is used to accommodate the instrument panel cross member 3 in the aforementioned inventive logistics apparatus, comprising:

[0051] Step 1: Place the device body of the aforementioned logistics device, with the top surface 1 of the device body facing upward.

At this time, the instrument panel bracket 33, the front panel bracket 35, the central bracket 36, and the cross beam mounting plate 311 of the lower instrument panel cross beam 3 are correspondingly accommodated in the first instrument panel bracket slot 13, the first front panel bracket slot 15, the first central bracket slot 16, and the air avoidance slot. Specifically, Figure 9-11 Graphic shown.

[0053] Step three, place the upper instrument panel cross beam 3 in the main body of the device. That is: accommodate no less than two instrument panel cross beams 3 with their front side facing downwards in the second cavity assembly, the cross beam 31 of the instrument panel cross beam 3 is engaged in the slot of the second cross beam support block 111, the assembly mounting bracket 32 ​​of the instrument panel cross beam 3 is engaged in the second assembly mounting bracket support slot 121, the navigation bracket 34 of the instrument panel cross beam 3 is supported on the top surface of the second navigation bracket support block 141, and the glove box bracket 37 of the instrument panel cross beam 3 is supported on the second glove box bracket support inclined surface 17. At this time, the instrument panel bracket 33 and the front panel bracket 35 of the upper instrument panel cross beam 3 are correspondingly accommodated in the second instrument panel bracket slot 131 and the second front panel bracket slot 151. Specifically, Figure 12-14 Graphic shown.

[0054] Step 4: stack another utensil body on the aforementioned utensil body, with the pressing transverse surface 21 of the upper utensil body supported on the supporting transverse surface 18 of the lower utensil body, and the bottom surface 2 of the upper utensil body supported on the top surface 1 of the lower utensil body.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
