Description

Technical Field

[0001] The present application relates to the technical field of automobile storage boxes, and in particular to a design method and structure of a universal front top storage box. Background Art

[0002] Currently, commercial vehicle front overhead storage boxes are generally standardized. They are categorized by width into three types: narrow, medium, and wide. Narrow boxes are used on light trucks, medium boxes on medium trucks, and wide boxes on heavy trucks. They are also categorized by height into two types: high-top and standard-top. To meet both domestic and international driving regulations, commercial vehicles require left- and right-hand steering wheels. Consequently, the workspace of commercial vehicle front overhead storage boxes also needs to adapt to the two steering wheel positions. Based on the width and height of the front overhead storage box and the corresponding steering wheel positions, there are 3 × 2 × 2 = 12 different variations of the front overhead storage box structure.

[0003] In the related art, all the existing commercial vehicle front roof storage boxes are one-piece molded structures. 12 different structures of front roof storage boxes require 12 sets of molds, inspection fixtures and tooling, which causes a lot of waste.

[0004] Therefore, technicians in this field are in urgent need of adopting new technical solutions to solve the technical problem that there are many types of front roof storage boxes for commercial vehicles, which require multiple sets of molds, inspection tools and tooling.

[0073] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only intended to illustrate the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0074] The design method and structure of the universal front top storage box of the present application are designed into a universal, strong and adjustable front top storage box structure through structural partitioning, which can be combined into 12 types of front top storage box structures, reducing the types of molds, inspection tools and tooling required for the production of front top storage boxes, and greatly reducing costs.

[0075] like Figures 1 to 11 As shown, the present application discloses an embodiment of a design method for a universal front roof storage box, which is used for commercial vehicles. The design method includes the following steps:

[0076] The front roof storage box of a high-top left-mounted wide vehicle for commercial vehicles is divided into 6 main blocks and 4 auxiliary decorative areas. The 6 main blocks are divided into two layers, and an auxiliary decorative area is set between every two main blocks.

[0077] Independently design each structure in 6 main block areas and 4 auxiliary decorative areas;

[0078] A universal bracket assembly was designed to support and install the various structures corresponding to the six main sub-areas and four auxiliary decorative areas. The universal bracket assembly also meets the flexible requirements of width, height, and left-right conversion of the twelve front top storage boxes.

[0079] Through flexible adjustment and matching, 12 different front-top storage boxes can be combined. Specifically, when changing width, the structure corresponding to any auxiliary decorative area is removed. The corresponding structures of the main sub-block areas on either side of the auxiliary decorative area can be perfectly matched and installed on the universal bracket assembly. Specifically, the corresponding structures of the main sub-block areas on both sides occupy the mounting positions of the corresponding structures of the auxiliary decorative area, achieving a perfect movable and transformable effect.

[0080] When the height is changed, the structures corresponding to the three main block areas on the upper layer are cancelled, and the structures corresponding to the three main block areas on the lower layer are moved to the structures corresponding to the three main block areas on the upper layer and installed on the universal bracket assembly.

[0081] When performing left-right replacement, the corresponding structures of the three main block areas on the upper layer remain stationary, the middle area of ​​the three main block areas on the lower layer remains stationary, and the corresponding structures of the main block areas on the left and right sides of the lower layer main block area are swapped and still installed on the universal bracket assembly.

[0082] The design method for a universal front roof storage box in this application achieves perfect flexibility by partitioning and structurally designing the structure of each area. When changing width, height, and left and right, the original structure's installation positions (including installation space and positioning holes) can be occupied. After the universal bracket assembly and the corresponding structural components for each area are produced, 12 types of front roof storage boxes can be assembled in different combinations. This greatly reduces the number of molds, inspection fixtures, and tooling required to produce commercial vehicle front roof storage boxes, significantly reducing costs.

[0083] like Figures 1 to 7As shown, in one embodiment, the six main sub-areas are the steering wheel top functional area A1, the middle decorative area B1, the open storage area C1, the first storage area A2, the second storage area B2, and the third storage area C2. The four auxiliary decorative areas are the first lower deformation area D1, the first upper deformation area D2, the second lower deformation area E1, and the second upper deformation area E2. The first lower deformation area D1 is located between the steering wheel top functional area A1 and the middle decorative area B1, and the first upper deformation area D2 is located between the first storage area A2 and the second storage area B2; the second lower deformation area E1 is located between the middle decorative area B1 and the open storage area C1; and the second upper deformation area E2 is located between the second storage area B2 and the third storage area C2.

[0084] In order to form 12 kinds of front top storage boxes in combination, the structure of the front top storage boxes must be able to be arbitrarily transformed in width and height.

[0085] Width transformation includes various situations, specifically:

[0086] The first type is a high-top wide car, in which the corresponding structures of the first lower deformation zone D1 and the first upper deformation zone D2 are cancelled and the car is transformed into a high-top medium car.

[0087] The second type is a high-top wide car, in which the corresponding structures of the second lower deformation zone E1 and the second upper deformation zone E2 are cancelled and transformed into a high-top medium car.

[0088] The third type is a high-top and wide vehicle, in which the corresponding structures of the first lower deformation zone D1, the first upper deformation zone D2, the second lower deformation zone E1 and the second upper deformation zone E2 are cancelled to form a high-top and narrow vehicle.

[0089] The fourth type is a standard top width car, in which the corresponding structure of the first lower deformation zone D1 is cancelled and transformed into a standard top medium car.

[0090] The fifth type is that the standard top width car cancels the corresponding structure of the second lower deformation zone E1 and transforms it into a standard top medium car.

[0091] The sixth type is a standard top wide vehicle, in which the corresponding structures of the first lower deformation zone D1 and the second lower deformation zone E1 are cancelled to form a standard top narrow vehicle.

[0092] Performing height transformation includes various situations, specifically:

[0093] The first type is that the high-top-width vehicle cancels the corresponding structures of the first storage area A2, the second storage area B2, the third storage area C2, the first upper deformation area D2 and the second upper deformation area E2, that is, cancels the structure corresponding to the entire upper main block area, and transforms it into a standard-top-width vehicle.

[0094] The second type is that the high-top CRRC cancels the structure corresponding to the entire upper main block area and transforms it into a standard-top CRRC.

[0095] The third type is a high-top narrow car, in which the structure corresponding to the entire upper main block area is cancelled and transformed into a standard-top narrow car.

[0096] Perform left-right transformation, including:

[0097] The functional area A1 on the top of the steering wheel and the open storage area C1 are directly swapped, and the structure of other local areas remains unchanged.

[0098] In one embodiment, the universal bracket assembly includes two vertical fixing brackets 1 in the vertical direction, one vertical fixing bracket 1 is arranged at the first lower deformation zone D1 and the first upper deformation zone D2, and the other vertical fixing bracket 1 is arranged at the second lower deformation zone E1 and the second upper deformation zone E2.

[0099] Furthermore, the universal bracket assembly includes an upper crossbeam 8, a lower crossbeam 10, an upper crossbeam fixed bracket 14 and a lower crossbeam fixed bracket 15 in the horizontal direction; the left and right ends of the upper crossbeam 8 and the lower crossbeam 10 are fixed to the left and right sides of the white body; the upper crossbeam fixed bracket 14 is an L-shaped steel structure, which is overlapped and fixed to the upper crossbeam 8, and the upper crossbeam fixed bracket 14 and the upper crossbeam 8 are arranged in the three main block areas of the upper layer; the lower crossbeam fixed bracket 15 is an open rectangular steel structure with upper and lower flanges, which is overlapped and fixed to the lower crossbeam 10, and the lower crossbeam fixed bracket 15 and the lower crossbeam 10 are arranged in the three main block areas of the lower layer.

[0100] It is worth noting that the upper side box bucket 2 and the middle upper box bucket 6 have different upper and lower widths. Figure 9 、 Figure 10 and Figure 11 In the figure, the wavy lines are omitted so that they look the same. At the same time, the upper and lower widths of the auxiliary decorative plate 22 are equal to the upper and lower widths of the button assembly 21, and Figure 10 and Figure 9 It looks different because the side upper box 2 and the middle upper box 6 are omitted.

[0101] In one embodiment, the structure corresponding to the top functional area A1 of the steering wheel is a button assembly 21, the structure corresponding to the middle decorative area B1 is a secondary center decorative panel 22, and the structure corresponding to the open storage area C1 is an open storage box 23.

[0108] Similarly, the high-top medium car is transformed into a high-top narrow car in width, the standard-top wide car is transformed into a standard-top medium car in width, and the standard-top medium car is transformed into a standard-top narrow car in width. The principles are similar, that is, the positions of the middle decorative area B1 and the second storage area B2 remain unchanged, and the remaining structures move left or right to occupy the space position and installation position of the cancelled structure.
