Description

Technical Field

[0001] The invention relates to a logistics device for a lower door trim panel, belonging to the technical field of packaging boxes. Background Art

[0002] Today, as the division of labor in the automotive industry develops rapidly, auto parts are usually manufactured by auto parts manufacturers scattered in different regions according to design drawings, and then transported to the assembly department of the auto company for unified assembly. In the process of auto parts leaving the factory, storage, transportation, and assembly, scientific selection of auto parts packaging boxes is conducive to minimizing transportation losses, reducing transportation costs, and improving transportation efficiency.

[0003] The lower door trim is mostly made of plastic. The main structure is the lower trim body connected to the lower door. Some lower door trims also include a fender plate connected to the lower trim body, which results in a large lateral size. In particular, the curved fender plate occupies a large amount of lateral packaging space, which is not conducive to improving logistics efficiency. The lower door trim is bent at the edge to form a flange, and a significantly raised connection seat is provided on the back. The flange and the connection seat are relatively fragile and are prone to breakage under pressure. These factors have caused certain difficulties in the packaging and transportation of the lower door trim. At present, when storing or transporting the lower door trim, it is usually placed in a wooden or paper packaging box and filled with flexible materials such as sponge and foam to prevent it from being damaged. This packaging method not only has the defects of poor shock absorption, loose fixation, and easy contamination, but also makes it difficult to take into account its own strength and weight at the same time, which is not conducive to improving packaging quality and improving logistics efficiency. Summary of the invention

[0004] In view of the deficiencies of the prior art, the purpose of the present invention is to provide a logistics device for lower door trim panels to solve the technical problems of low space utilization, loose fixation and easy contamination of lower door trim panel packaging boxes in the prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A logistics device for a lower door trim panel comprises a device body, wherein the top surface of the device body is inwardly recessed to form a cavity matched with the front contour of the lower door trim panel.

[0007] Preferably, there are no less than two cavities and they are staggered on the left and right.

[0008] Preferably, the mold cavity comprises a main body mold cavity and an eyebrow plate mold cavity which are connected to each other, and the eyebrow plate mold cavities of the left and right mold cavities are staggered opposite to each other;

[0009] The body cavity accommodates the lower trim body of the vehicle door lower trim, and the eyebrow plate cavity accommodates the wheel eyebrow plate of the vehicle door lower trim.

[0010] Preferably, the door lower trim panel includes a right door lower trim panel and a left door lower trim panel, the mold cavity includes a first mold cavity for accommodating the right door lower trim panel and a second mold cavity for accommodating the left door lower trim panel, and the first mold cavity and the second mold cavity are cross-overlapped in the same direction;

[0011] The first cavity and the second cavity that overlap in the same direction are combined to form a composite cavity.

[0012] Preferably, there are no less than two composite cavities arranged in a front-to-back order, and two adjacent composite cavities partially overlap in the same direction;

[0013] A diamond-shaped boss is formed between the two composite cavities which partially overlap in the same direction.

[0014] Preferably, there are no less than two tool bodies and they are distributed longitudinally, the top surface of the body is inwardly recessed to form a support groove surface, and the mold cavity is formed on the support groove surface;

[0015] The bottom surface of the main body of the device body protrudes outward to form a sunken boss corresponding to the support groove surface.

[0016] Preferably, the sunken boss is provided with an air-avoiding groove or / and a material-reducing groove formed by an inward depression;

[0017] The air avoidance groove corresponds to the connecting seat of the lower door trim panel accommodated in the cavity.

[0018] Preferably, the material reduction groove is communicated with the bottom surface of the body.

[0019] Preferably, the cavity surface of the cavity is hollowed out inwardly to form a hollow opening.

[0020] Preferably, the logistics equipment is made of EPS material.

[0021] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the logistics equipment of the present invention is formed by stacking a number of equipment bodies in the longitudinal direction. The equipment body has a support groove surface formed by the inward depression of the top surface of the body. The support groove surface is inwardly depressed to form a cavity for accommodating the lower door trim panel laterally, which plays a role of lateral position limiting for the lower door trim panel. The bottom surface of the body is outwardly protruding to form a sinking boss. The sinking boss of the upper equipment body sinks to the support groove surface of the lower equipment body, which plays a role of longitudinal position limiting for the lower door trim panel in the lower equipment body, thereby firmly fixing the lower door trim panel on the equipment body and avoiding white pollution caused by fillers. Due to the cavity sinking design, while playing a role of lateral position limiting for two adjacent equipment bodies, it is also beneficial to reduce the height of each layer of equipment body, so as to improve the utilization rate of packaging space and enhance logistics efficiency. The cavity support groove surface is staggered on the left and right, which reduces the left and right dimensions of the equipment body and makes full use of the limited lateral space on the equipment body. The logistics device of the present invention is made of EPS material and has the advantages of good load-bearing capacity, good cushioning and light weight. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] 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 solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[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 the present invention to 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 embodiment of the present invention provides a logistics device for the lower trim panel of a vehicle door, which is composed of a plurality of device bodies stacked and arranged in a longitudinal direction. The device body is made of expanded polystyrene (EPS) in one piece. EPS is a light polymer, which is formed by adding a foaming agent to polystyrene resin and heating it to soften it, 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 , Figure 8 , which are respectively the front and back perspective views of the lower door trim panel in the embodiment of the present invention, the lower door trim panel 5 comprises a lower trim panel body 51 and a fender 52 connected to the end thereof, and one side edge of the lower trim panel body 51 and the fender 52 is bent toward the back thereof to form a flange 53. The front of the lower door trim panel 5 is relatively flat and smooth, and a plurality of significantly protruding connection seats 54 are provided on the back thereof. The lower door trim panel 5 comprises a right lower door trim panel and a left lower door trim panel, and the figure shows the right lower door trim panel.

[0037] like Figures 1 to 5 As shown, they are respectively a top stereogram, a bottom stereogram, a top view, a front view, and a bottom view of the device body in the embodiment of the present invention. The top surface 3 of the device body is recessed inward to form a support groove surface 31, and the support groove surface 31 is recessed inward to form a cavity that matches the front contour of the lower door trim 5. The lower door trim 5 is received in the cavity with its front side facing downward, and the cavity serves as a lateral limit for the lower door trim 5.

[0038] The bottom surface 4 of the device body bulges outward, forming a sunken boss 41 corresponding to the support groove surface 31, that is, the cavity on the support groove surface 31 is designed to sink to reduce the height of the cavity surface of the cavity. The sunken boss 41 is provided with an air avoidance groove 42 formed by an inward depression, and the air avoidance groove 42 corresponds to the connecting seat 54 on the back of the lower door trim 5 accommodated in the cavity. When multiple device bodies are stacked, the sunken boss 41 of the upper device body sinks to the support groove surface 31 of the lower device body, and the bottom surface 4 of the upper device body contacts the top surface 3 of the lower device body. The sunken boss 41 of the upper device body interacts with the support groove surface 31 of the lower device body, which plays a lateral limiting role for the two adjacent stacked device bodies to prevent each other from sliding laterally and causing overturning. The sunken boss 41 of the upper device body plays a longitudinal limiting role for the lower door trim 5 accommodated by the lower device body. The cavity sinking design is conducive to reducing the height of each layer of the appliance body, thereby improving the utilization rate of packaging space and enhancing logistics efficiency. The connection seat 54 that is significantly raised on the back of the lower door trim 5 is accommodated in the air-avoiding groove 42 of the upper appliance body to avoid damage caused by pressure on the connection seat 54.

[0039] The sinking boss 41 is also provided with a material reduction groove 43 formed inwardly concave, which plays a role in saving materials and reducing weight. The material reduction groove 43 provided at the edge of the sinking boss 41 is connected to the bottom surface 4 of the body, which can avoid the negative pressure between the sinking boss 41 of the upper device body and the supporting groove surface 31 of the lower device body due to factors such as air temperature, which makes it difficult to separate.

[0040] The appliance body is composed of the first appliance part 1 on the left and the second appliance part 2 on the right, thereby reducing the size of a single product and facilitating production and transportation. The first appliance part 1 and the second appliance part 2 are transported to a designated location and assembled together for use. The first appliance part 1 and the second appliance part 2 are connected by a mortise and tenon structure to ensure the stability of the connection between the two, which is convenient for load bearing and storage and transportation.

[0041] The cavity is structurally distinguished, including a main body cavity and an eyebrow plate cavity that are connected to each other. The main body cavity accommodates the lower trim body 51 of the lower door trim 5, and the eyebrow plate cavity accommodates the wheel eyebrow plate 52 of the lower door trim 5; from the type, it includes a first cavity for accommodating the right lower door trim and a second cavity for accommodating the left lower door trim. In this embodiment, the first device split body 1 and the second device split body 2 are each provided with four first cavities and four second cavities. The cavity surface of the first cavity includes a first body cavity surface 32 and a first wheel eyebrow plate cavity surface 33, corresponding to accommodating the lower trim body 51 and the wheel eyebrow plate 52 of the lower door trim of the right vehicle. The cavity surface of the second cavity includes a second body cavity surface 34 and a second wheel eyebrow plate cavity surface 35, corresponding to accommodating the lower trim body 51 and the wheel eyebrow plate 52 of the lower door trim of the right vehicle. It should be noted that one device body cannot accommodate the lower right door trim and the lower left door trim at the same time, and can only accommodate one of them at a time. The logistics device of the present invention can accommodate both left and right door lower trims, which improves the versatility of the product and helps reduce mold opening and operating costs. The cavity surface of the cavity is hollowed out inward to form a hollow opening 38, which saves material and reduces weight; the hollow opening 38 provided on the first body cavity surface 32 and the second body cavity surface 34 can also prevent the lower trim body 51 from being difficult to separate from the cavity due to negative pressure.

[0042] The first cavity and the second cavity cross and overlap in the same direction on the support groove surface 31. Taking the cavity in the first tool split 1 as an example, the first body cavity surface 32 and the second body cavity surface 34 are both located on the left side, but the lateral inclination angles of the first cavity and the second cavity are slightly different, that is, they cross in the same direction. The first cavity and the second cavity that cross and overlap in the same direction are combined to form a composite cavity. There are four composite cavities on the first tool split 1. The composite cavity has a continuously distributed V-shaped edge 37 on one side close to the edge of the tool body to adapt to the end structure of the two lower door trim panels 5 with crossing angles. The four composite cavities are arranged in sequence front and back on the support groove surface 31, and the adjacent composite cavities partially overlap in the same direction. At this time, the lateral inclination angles of the two composite cavities are the same. A diamond boss 36 is formed between the two composite cavities that overlap in the same direction, and the top surface of the diamond boss 36 is the support groove surface 31. The diamond boss 36 has a limiting effect on the lower door trim panels 5 received in the two adjacent front and rear cavities. Taking the first tool split body 1 as an example, when receiving the right lower door trim panel, the front and rear sides of the diamond boss 36 have a limiting effect on the lower door trim panel 5; when receiving the left lower door trim panel, the left and right sides of the diamond boss 36 have a limiting effect on the lower door trim panel 5. The significance of the design of the composite cavity and the diamond boss 36 is to make full use of the limited horizontal space on the tool body while improving the versatility of the product, to receive more lower door trim panels 5, and thus to improve logistics efficiency.

[0043] When the first tool body 1 and the second tool body 2 are combined together, the overall structure presented at this time is: the cavities are staggered on the left and right sides of the support groove surface 31, that is, the eyebrow plate cavities of the left and right cavities are staggered oppositely on the support groove surface 31. The significance of the left and right staggered design of the cavities is also to make full use of the limited horizontal space on the tool body to improve logistics efficiency.

[0044] like Figure 6 As shown, it is a top three-dimensional view of the first tool split body in the embodiment of the present invention. The left edge of the first tool split body 1 is the left edge of the tool body, the first body cavity surface 32 and the second body cavity surface 34 are arranged near the left edge of the first tool split body 1, and the first body cavity surface 32 and the second body cavity surface 34 are arranged in sequence from front to back on the first tool split body 1. The right edge of the first tool split body 1 is the front-to-back midline of the tool body, the first wheel eyebrow plate cavity surface 33 and the second wheel eyebrow plate cavity surface 35 are arranged near the right edge of the first tool split body 1, and the first wheel eyebrow plate cavity surface 33 and the second wheel eyebrow plate cavity surface 35 are arranged in sequence from back to front on the first tool split body 1. The right end surface of the first tool split body 1 is provided with a tenon convex 11 formed by protruding outward and a mortise 21 formed by concave inward, and the tenon convex 11 and the mortise 21 are arranged in sequence from front to back on the right end surface of the first tool split body 1. The first tool split 1 and the second tool split 2 have the same structure. The first tool split 1 is rotated 180 degrees to form the second tool split 2. The assembly method of the tool body is as follows: first, the first tool split 1 is placed on the left side, and the second tool split 2 is placed on the right side. The two are arranged in a trapezoidal shape, and the first tool split 1 is higher than the second tool split 2. Then, the first tool split 1 is pressed down in the longitudinal direction, so that the tenon 11 on the first tool split 1 is pressed into the mortise 21 on the second tool split 2, and the mortise 21 on the first tool split 1 is pressed into the tenon 11 on the second tool split 2, thereby completing the combination of the first tool split 1 and the second tool split 2 to form a complete tool body.

[0045] like Fig. 9 As shown, it is a top perspective view of the device body receiving the right door lower trim panel in the embodiment of the present invention, and the right door lower trim panel can be received in four first cavities of the first device body 1 and the second device body 2. Fig.10 , is a top perspective view of the apparatus body receiving the left door lower trim panel in an embodiment of the present invention, and the left door lower trim panel can be received in four first cavities of the first apparatus body 1 and the second apparatus body 2. For the convenience of display, Fig. 9 and Fig.10Only three lower door trim panels 5 are accommodated in the figure. It can be seen that the lower door trim panels 5 accommodated along the front and rear directions are arranged in sequence in their respective cavities, making full use of the front and rear space of the device body; the lower door trim panels 5 accommodated along the left and right directions are arranged alternately in their respective cavities, reducing the left and right dimensions of the device body and making full use of the limited horizontal space on the device body.

[0046] 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.
