DETAILED DESCRIPTION

[0033] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0034] It should be noted that in the description of the present invention, the directions or positional relationships indicated by the terms "front", "rear", "left", "right", "up", "down", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention rather than requiring that the present invention must be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. The terms "front", "rear", "left", "right", "up", and "down" used in the description of the present invention refer to the directions in the accompanying drawings, and the terms "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0035] The specific implementation of the utility model provides a logistics device for a dashboard crossbeam, which is composed of a plurality of device bodies stacked and assembled in the longitudinal direction. The device body is made of polystyrene foam (EPS) in one piece. EPS is a light polymer, which is made of polystyrene resin with a foaming agent added, and heated to soften, generating gas to form a rigid closed-cell foam plastic, which has the characteristics of low water absorption, good heat preservation, light weight and high mechanical strength.

[0036] like Figure 7 , 8 As shown in the figure, they are the front and back structural diagrams of the instrument panel cross beam in the embodiment of the utility model. The instrument panel cross beam 3 mainly includes a cross beam 31, and the two ends of the cross beam 31 are provided with assembly mounting brackets 32 facing the front, and the two ends of the cross beam 31 are provided with cross beam mounting plates 311 facing the back. The front of the cross beam 31 is provided with an instrument panel bracket 33, a front wall bracket 35, and a glove box bracket 37 from left to right. The central section of the cross beam 31 is provided with a navigation bracket 34 downward, and the left side of the navigation bracket 34 is provided with an instrument panel mounting plate 341 that cooperates with the instrument panel bracket 33. The back of the central section of the cross beam 31 is provided with a central bracket 36. It can be seen from the figure that the overall structure of the instrument panel cross beam 3 is relatively loose, and there are many significant protruding parts such as the cross beam mounting plate 311, the assembly mounting bracket 32, the navigation bracket 34, the front wall bracket 35, and the glove box bracket 37 along the radial direction of the cross beam 31. When multiple instrument panel cross beams 3 are packed at the same time, there is interference 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 forces in other directions, otherwise it may cause deformation and damage.

[0037] Based on the above structural characteristics of the instrument panel cross beam 3, the logistics device of the utility model has carried out targeted design and technical improvements. Figure 1-6 As shown, they are respectively a top stereogram, an upper view, a bottom stereogram, a lower view, a front view, and a left view of the device body in the embodiment of the utility model. The top surface 1 of the device body is recessed inward to form a cavity, and a plurality of cavity assemblies for accommodating the instrument panel cross beam 3 are arranged in the cavity, including a first cavity assembly and a second cavity assembly alternately distributed in the horizontal direction, and the second cavity assembly is higher than the first cavity assembly. The significance of this design is that the device body can accommodate two layers of instrument panel cross beams 3, that is, the first cavity assembly accommodates the lower instrument panel cross beam 3, and the second cavity assembly accommodates the upper instrument panel cross beam 3.

[0038] 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 downward. Figure 8 The significance of this design is that, firstly, the crossbeam 31, the assembly mounting bracket 32, and the navigation bracket 34 jointly support the weight of the instrument panel crossbeam 3 to ensure balanced force; secondly, the front wall bracket 35 and the glove box bracket 37, which are significantly protruding in the radial direction of the upper and lower instrument panel crossbeams 3, are both accommodated in the cavity without occupying additional longitudinal space, and avoid interference with each other.

[0039] 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.

[0040] 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 grooves matched with 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 matched with the bottom surface shape of the navigation bracket 34 in the storage posture, which plays a role of 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 matched with the bottom surface shape of the glove box bracket 37 of the upper instrument panel crossbeam 3 in the storage posture.

[0041] The first instrument panel bracket groove 13, the first front wall bracket groove 15, and the first central bracket groove 16 are used to accommodate the instrument panel bracket 33, the front wall bracket 35, and the central bracket 36 of the lower instrument panel cross beam 3, and the second instrument panel bracket groove 131 and the second front wall bracket groove 151 are used to accommodate the instrument panel bracket 33 and the front wall bracket 35 of the upper instrument panel cross beam 3. All of the above are the accommodating structures of the device body, wherein the first instrument panel bracket groove 13, the second instrument panel bracket groove 131, the first front wall bracket groove 15, and the second front wall bracket groove 151 are all formed by being recessed inward from the side of the cavity; the first central bracket groove 16 is formed by being recessed inward from the bottom of the cavity.

[0042] Preferably, the first assembly mounting bracket support groove 12 is recessed inward to form a space-avoiding groove adapted to the crossbeam mounting plate 311 of the instrument panel crossbeam 3, which is used to space-avoidably accommodate the crossbeam mounting plate 311 that protrudes significantly outward on the back side of the lower instrument panel crossbeam 3 to avoid damage due to pressure.

[0043] Preferably, the top surface 1 of the body is recessed inward to form a supporting transverse surface 18, and the bottom surface 2 of the body of the utensil body is recessed inward to form a pressing transverse surface 21 adapted to the supporting transverse surface 18, that is, the pressing transverse surface 21 has the same position and size as the supporting transverse surface 18, and the depth of the supporting transverse surface 18 compared to the top surface 1 of the body is the same as the depth of the pressing transverse surface 21 compared to the bottom surface 2 of the body. This ensures that when multiple utensil bodies are stacked, the protrusion at the bottom of the upper utensil body is just embedded in the groove at the top of the lower utensil body, that is, the pressing transverse surface 21 of the upper utensil body is supported on the supporting transverse surface 18 of the lower utensil body, and the bottom surface 2 of the upper utensil body is supported on the top surface 1 of the lower utensil body, thereby limiting the lateral movement of adjacent utensil bodies and avoiding overturning when stacked. Compared with the conventional limiting column / limiting groove method, this limiting method has a larger contact area, and thus has more advantages in limiting effect. Under this structural design, the cavity is formed by the support transverse surface 18 being recessed inward.

[0044] Preferably, a pressing side surface 22 is formed between the pressing horizontal surface 21 and the bottom surface 2 of the body, and the pressing side surface 22 is provided with a side groove 221 formed by being recessed inwardly. When adjacent appliance bodies are stacked or separated, the internal air can be discharged outwardly through the side groove 221, thereby avoiding the difficulty of operation caused by negative pressure. The bottom surface 2 of the body is recessed inwardly to form a through hole 23 that penetrates to the bottom surface of the cavity, which also plays the same role and is conducive to reducing weight and saving materials.
