DETAILED DESCRIPTION

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in a clear and complete manner with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0024] The existing commercial vehicle cab side wall generally has three columns, front, middle and rear, which are respectively referred to as A column, B column and C column. The B column and the C column are two independent systems. There are many functions to be implemented between the B column and the C column, such as providing installation for interior trim panels, providing installation for bunk lights, providing installation for side windows, providing support for side wall outer plates, providing installation for wire harnesses, etc. These functions need to increase sheet metal components to provide support. There are many components between the B column and the C column. When manufacturing multiple components, different molds need to be used, and each component also needs to be coated with independent paint, which increases the processing cost of the components.

[0025] The embodiments of the present application provide a side wall structure fusing a B column and a C column and a vehicle thereof, which can solve the problem of high processing cost of components when the components are manufactured separately due to the large number of components between the B column and the C column in the related art.

[0026] Among them, the B column is a longitudinal dumbbell between the front seat and the rear seat in the cab, i.e. between the two doors on both sides, and the B column extends from the roof to the bottom; the C column is used to support the roof and the rear windshield, mainly to bear and disperse the impact force during rear-end collision.

[0027] In order to facilitate the understanding of the technical solutions of the present application, as Figure 1 , Figure 2 indicated, the present application sets the cab width (vehicle body width) direction as the X direction, sets the cab length (vehicle body length) direction as the Y direction, as Figure 3 indicated, sets the cab height (vehicle body height) direction as the Z direction.

[0028] Referring to Figures 1 to 5 As shown in the drawings, the embodiment of the present application provides a side wall structure integrating B column and C column, which comprises a B column inner plate 3, a C column inner plate 4 and an integration plate 5, the integration plate 5 is arranged between the B column inner plate 3 and the C column inner plate 4; wherein the B column inner plate 3, the C column inner plate 4 and the integration plate 5 are integrally formed.

[0029] In the present application, the B column inner plate 3, the C column inner plate 4 and the integration plate 5 are arranged as an integrally formed structure, a plurality of small components are integrated into one large component, the number of components is reduced, and since the number of components is reduced, the number of molds is reduced, the labor and equipment investment for stamping and welding are greatly reduced, at the same time, the structure can be painted together with the body-in-white, the paint cost is reduced, and then the component manufacturing cost is reduced.

[0030] As shown in the drawings, Figure 4 The components distributed in the first area 7, the second area 8, the third area 9, the fourth area 10 and the fifth area 11 are combined into one component. Wherein the first area 7 is a B column area, the second area 8 is a C column area, the third area 9 is a side wall outer plate support area, the fourth area 10 is an interior trim panel mounting area, and the fifth area 11 is a sleeper lamp bracket area. That is, the components distributed in the B column area, the C column area, the side wall outer plate support area, the interior trim panel mounting area and the sleeper lamp bracket area are combined into one component.

[0031] Wherein the B column inner plate 3 and the C column inner plate 4 are respectively distributed in the B column area and the C column area, and the integration plate 5 comprises a side wall outer plate reinforcing plate 50, an interior trim panel bracket 51 and a sleeper lamp bracket 52. The side wall outer plate reinforcing plate 50, the interior trim panel bracket 51 and the sleeper lamp bracket 52 are respectively distributed in the side wall outer plate support area, the interior trim panel mounting area and the sleeper lamp bracket area. Wherein the side wall outer plate reinforcing plate 50, the interior trim panel bracket 51 and the sleeper lamp bracket 52 are connected with each other and are integrally formed, and constitute the integration plate 5.

[0032] One end of the integration plate 5 is connected with the B column inner plate 3, and the other end is connected with the C column inner plate 4. Specifically, along the length direction of the cab, the side wall outer plate reinforcing plate 50 is located between the B column inner plate 3 and the C column inner plate 4, and the interior trim panel bracket 51 and the sleeper lamp bracket 52 are also located between the B column inner plate 3 and the C column inner plate 4.

[0033] The side wall structure further comprises a side wall outer plate body 1 and a door frame 2, as Figure 1 , Figure 2As shown, after the B-pillar inner panel 3, the C-pillar inner panel 4, the side wall outer plate reinforcing plate 50, the interior panel support 51 and the bunk lamp support 52 are integrally formed, the B-pillar inner panel 3 is further connected with the door frame 2, one end of the side wall outer plate body 1 is connected with the door frame 2, and the other end is connected with the C-pillar inner panel 4. And between the fusion plate 5 and the side wall outer plate body 1, there is a reinforcing glue 6, specifically, between the side wall outer plate reinforcing plate 50 and the side wall outer plate body 1, there is a reinforcing glue 6, which positions the side wall outer plate reinforcing plate 50 and the side wall outer plate body 1 through the reinforcing glue 6. The material of the reinforcing glue 6 can be thermosetting epoxy resin, which fixes the side wall outer plate reinforcing plate 50 and the side wall outer plate body 1 by structural glue, reduces the welding tooling design, and at the same time, the reinforcing glue 6 can be applied on the fragile parts of the side wall outer plate reinforcing plate 50 and the side wall outer plate body 1, which can also play the role of sound insulation and shock absorption, and enhance the strength of the side wall outer plate reinforcing plate 50 and the side wall outer plate body 1.

[0034] On the basis of the above embodiment, in this embodiment, between the side wall outer plate reinforcing plate 50, the interior panel support 51 and the bunk lamp support 52 along the height direction of the cab, there is also a bevel plate 53, and the side wall outer plate reinforcing plate 50, the interior panel support 51, the bunk lamp support 52 and the bevel plate 53 are integrally formed. Specifically, when the fusion plate 5 is connected, first consider connecting the side wall outer plate reinforcing plate 50 with the B-pillar inner panel 3 and the C-pillar inner panel 4 to merge into one whole part, then consider connecting the interior panel support 51 and the bunk lamp support 52 with the B-pillar inner panel 3 and the C-pillar inner panel 4 to merge into one whole part, and further, the two whole parts are merged into one large part. Since the side wall outer plate reinforcing plate 50, the interior panel support 51 and the bunk lamp support 52 are arranged along the height direction of the cab, there is a height difference between the side wall outer plate reinforcing plate 50 and the interior panel support 51, and between the interior panel support 51 and the bunk lamp support 52, therefore, in order to connect the side wall outer plate reinforcing plate 50, the interior panel support 51 and the bunk lamp support 52 into one body, the bevel plate 53 is arranged between the side wall outer plate reinforcing plate 50, the interior panel support 51 and the bunk lamp support 52. The side wall outer plate reinforcing plate 50 is connected with the interior panel support 51 through the bevel plate 53; the interior panel support 51 is connected with the bunk lamp support 52 through the bevel plate 53, so that the side wall outer plate reinforcing plate 50, the interior panel support 51, the bunk lamp support 52 and the bevel plate 53 are integrally formed.

[0035] Because of the increase of the inclined panel 53, in order to ensure that the weight of the side wall structure of the present application does not increase compared with the total weight of the B-pillar inner panel 3, the C-pillar inner panel 4, the side wall outer panel reinforcing plate 50, the interior panel support 51 and the bunk light support 52 in the prior art, the side wall outer panel reinforcing plate 50 is provided to include a first reinforcing plate 500 and a second reinforcing plate 501, and there is a gap between the first reinforcing plate 500 and the second reinforcing plate 501 in the direction of the height of the cab; the interior panel support 51 is provided to include a first support body 510 and a second support body 511, and there is a gap between the first support body 510 and the second support body 511 in the direction of the height of the cab. Specifically, as shown in Figure 1 and Figure 2 in the direction of the length of the cab, the side wall outer panel reinforcing plate 50, the interior panel support 51 and the bunk light support 52 are all connected with the B-pillar inner panel 3 and the C-pillar inner panel 4, as shown in Figure 3 the inclined panel 53 needs to be added between the side wall outer panel reinforcing plate 50, the interior panel support 51 and the bunk light support 52, and in the direction of the width of the cab, the side wall outer panel reinforcing plate 50 and the interior panel support 51 overlap in part, so on the basis of not affecting the arrangement of other structures in the cab, the part of the side wall outer panel reinforcing plate 50 overlapping with the interior panel support 51 is cancelled, so as to offset the added inclined panel 53.

[0036] Therefore, the structure of the existing side wall outer panel reinforcing plate 50 is changed, the side wall outer panel reinforcing plate 50 in the present application includes a first reinforcing plate 500 and a second reinforcing plate 501, and a gap is provided between the first reinforcing plate 500 and the second reinforcing plate 501; the structure of the existing interior panel support 51 is changed, the interior panel support 51 in the present application includes a first support body 510 and a second support body 511, and a gap is provided between the first support body 510 and the second support body 511. The first reinforcing plate 500, the second reinforcing plate 501, the first support body 510 and the second support body 511 are connected with each other through the inclined panel 53.

[0037] Further, the first reinforcing plate 500, the second reinforcing plate 501, the first frame body 510 and the second frame body 511 are specifically arranged as follows: the first frame body 510 is located between the first reinforcing plate 500 and the second reinforcing plate 501, and the second reinforcing plate 501 is located between the first frame body 510 and the second frame body 511. In the driving cab height direction, the first reinforcing plate 500, the second reinforcing plate 501, the first frame body 510 and the second frame body 511 are vertically arranged, and the inclined plate 53 is arranged obliquely in the driving cab width direction. The first reinforcing plate 500 is connected to the first frame body 510 through one inclined plate 53, and in the driving cab height direction, the first frame body 510 is located on the top of the first reinforcing plate 500; the first frame body 510 is connected to the second reinforcing plate 501 through one inclined plate 53, and in the driving cab height direction, the second reinforcing plate 501 is located on the top of the first frame body 510; the second reinforcing plate 501 is connected to the second frame body 511 through one inclined plate 53, and in the driving cab height direction, the second frame body 511 is located on the top of the second reinforcing plate 501. The first reinforcing plate 500 and the second reinforcing plate 501 are located on the same side of the inclined plate 53, the first frame body 510 and the second frame body 511 are located on the same side of the inclined plate 53, and the first reinforcing plate 500, the second reinforcing plate 501, the first frame body 510 and the second frame body 511 are located on different sides of the inclined plate 53. In the driving cab height direction, the bunk lamp bracket 52 is located at the bottom of the second frame body 511, and an inclined plate 53 is also connected between the bunk lamp bracket 52 and the second frame body 511, and in the driving cab height direction, the bunk lamp bracket 52 is vertically arranged, so that the second reinforcing plate 501 is connected to the second frame body 511 through two inclined plates 53 and the bunk lamp bracket 52.

[0038] Further, in order to further reduce the weight of the side wall structure, the B-pillar inner plate 3, the C-pillar inner plate 4 and the fusion plate 5 have the same thickness. Here, the same thickness means that on the basis of the existing scheme and under the condition of ensuring the safety performance of the automobile, the thickness of some components is reduced, so that the thickness of the B-pillar inner plate 3, the C-pillar inner plate 4 and the fusion plate 5 is consistent. In order to make it clearer, the following examples are given, for example: the general thickness of the existing B-pillar inner plate 3, C-pillar inner plate 4 and side wall outer plate reinforcing plate 50 is 0.8mm, and the thickness of the interior trim bracket 51 and the bunk lamp bracket 52 is generally 1.5mm. In this application, the thickness of the B-pillar inner plate 3, the C-pillar inner plate 4, the side wall outer plate reinforcing plate 50, the interior trim bracket 51 and the bunk lamp bracket 52 is uniformly 0.8mm. By reducing the thickness of the interior trim bracket 51 and the bunk lamp bracket 52, the weight of the side wall structure is reduced.

[0039] Further, in order to compensate for the insufficient local rigidity caused by the thickness reduction of some components, the reinforcing ribs 55 are connected to the fusion plate 5 at positions where the local rigidity is insufficient, for example, if the thickness of the interior trim plate support 51 and the bunk lamp support 52 is reduced, the local rigidity of the interior trim plate support 51 and the bunk lamp support 52 needs to be enhanced by adding reinforcing ribs 55. At the same time, the reinforcing ribs 55 are arranged around the mounting point 12 without affecting the mounting and connection of the fusion plate 5 and other structures of the cab. On this basis, since the reinforcing ribs 55 are arranged at positions where the local rigidity of the fusion plate 5 is insufficient, in order to compensate for the increased weight of the reinforcing ribs 55, the weight reduction holes 54 are provided in the fusion plate 5 under the condition of ensuring the safety performance of the automobile, and the weight reduction holes 54 can be arranged between two reinforcing ribs 55.

[0040] In summary, by reducing the thickness of some components and providing the weight reduction holes 54, the weight of the side wall structure can be ensured not to increase, and by providing the reinforcing ribs 55, the structural strength of the side wall structure is ensured.

[0041] In terms of the manufacturing cost of the side wall structure, the side wall outer plate reinforcing plate 50, the interior trim plate support 51 and the bunk lamp support 52, the B-pillar inner plate 3 and the C-pillar inner plate 4 are changed into one component, reducing the number of molds from fifteen sets of molds for five components to three sets of molds for one component, reducing the manufacturing cost of the components due to the reduction in the number of molds and the reduction in the material blank, greatly reducing the labor and equipment investment for stamping and welding, saving process make-up surfaces when five components are changed into one component, and reducing the paint cost when the structure is painted together with the body-in-white. In summary, the cost of the side wall structure can be reduced.

[0042] In a second aspect, the embodiments of the present application provide an automobile including the side wall structure of the fusion B-pillar and C-pillar provided by any of the embodiments of the present application. The embodiments of the present application do not limit the specific structure of the automobile.

[0043] In the present application, the B-pillar inner plate 3, the C-pillar inner plate 4 and the fusion plate 5 are provided as an integrally formed structure, a plurality of small components are integrated into one large component, the number of components is reduced, the number of molds is reduced due to the reduction in the number of components, the labor and equipment investment for stamping and welding is greatly reduced, the structure can be painted together with the body-in-white, the paint cost is reduced, and the manufacturing cost of the components is further reduced.

[0044] As Figure 4As shown, the components distributed in the first region 7, the second region 8, the third region 9, the fourth region 10, and the fifth region 11 are combined into one component. Specifically, the first region 7 is the B-pillar region, the second region 8 is the C-pillar region, the third region 9 is the side panel support region, the fourth region 10 is the interior panel mounting region, and the fifth region 11 is the sleeper light bracket region. In other words, this application combines the components distributed in the B-pillar region, C-pillar region, side panel support region, interior panel mounting region, and sleeper light bracket region into one component.

[0045] The B-pillar inner panel 3 and C-pillar inner panel 4 are located in the B-pillar and C-pillar areas, respectively. The fusion panel 5 includes a side outer panel reinforcement plate 50, an interior panel bracket 51, and a sleeper light bracket 52. The side outer panel reinforcement plate 50, interior panel bracket 51, and sleeper light bracket 52 are located in the side outer panel support area, the interior panel mounting area, and the sleeper light bracket area, respectively. The side outer panel reinforcement plate 50, interior panel bracket 51, and sleeper light bracket 52 are interconnected and form a single, integrally molded structure, constituting the fusion panel 5.

[0046] One end of the fusion plate 5 is connected to the inner panel 3 of the B-pillar, and the other end is connected to the inner panel 4 of the C-pillar. Specifically, along the length of the cab, the outer panel reinforcement plate 50 of the side wall is located between the inner panel 3 of the B-pillar and the inner panel 4 of the C-pillar. The interior panel bracket 51 and the sleeper light bracket 52 are also located between the inner panel 3 of the B-pillar and the inner panel 4 of the C-pillar.

[0047] The side panel structure also includes the side panel body 1 and the door frame 2, such as Figure 1 , Figure 2 As shown, after the B-pillar inner panel 3, C-pillar inner panel 4, side outer panel reinforcing plate 50, interior panel bracket 51, and sleeper light bracket 52 are integrally formed, the B-pillar inner panel 3 is still connected to the door frame 2. One end of the side outer panel body 1 is connected to the door frame 2, and the other end is connected to the C-pillar inner panel 4. A reinforcing adhesive 6 is provided between the fusion plate 5 and the side outer panel body 1 to position them. The reinforcing adhesive 6 can be made of thermosetting epoxy resin. By using structural adhesive to bond and fix the fusion plate 5 and the side outer panel body 1, welding tooling design is reduced. At the same time, applying the reinforcing adhesive 6 to the vulnerable parts of the fusion plate 5 and the side outer panel body 1 also provides sound insulation and vibration reduction, and enhances the strength of the fusion plate 5 and the side outer panel body 1.

[0048] On the basis of the above-mentioned embodiments, in the present embodiment, between the side wall outer plate reinforcing plate 50, the interior trim panel support 51 and the bunk light support 52 in the cab height direction, there is further connected a bevel plate 53, and the side wall outer plate reinforcing plate 50, the interior trim panel support 51, the bunk light support 52 and the bevel plate 53 are of an integrated molding structure. Specifically, when the fusion plate 5 is connected, firstly, the side wall outer plate reinforcing plate 50 is considered to be connected with the B-pillar inner plate 3 and the C-pillar inner plate 4, and to be combined into one integral component, then the interior trim panel support 51 and the bunk light support 52 are considered to be connected with the B-pillar inner plate 3 and the C-pillar inner plate 4, and to be combined into one integral component, further, the two integral components are combined into one large component. Since the side wall outer plate reinforcing plate 50, the interior trim panel support 51 and the bunk light support 52 are arranged in the cab height direction, there is a height difference between each side wall outer plate reinforcing plate 50 and the interior trim panel support 51, and between the interior trim panel support 51 and the bunk light support 52, therefore, in order to connect the side wall outer plate reinforcing plate 50, the interior trim panel support 51 and the bunk light support 52 into one body, the bevel plate 53 is arranged between the side wall outer plate reinforcing plate 50, the interior trim panel support 51 and the bunk light support 52. The side wall outer plate reinforcing plate 50 is connected with the interior trim panel support 51 through the bevel plate 53; the interior trim panel support 51 is connected with the bunk light support 52 through the bevel plate 53, so that the side wall outer plate reinforcing plate 50, the interior trim panel support 51, the bunk light support 52 and the bevel plate 53 are of an integrated molding structure.

[0049] Due to the structure of adding the bevel plate 53, in order to ensure that the total weight of the side wall structure of the present application does not increase compared with the B-pillar inner plate 3, the C-pillar inner plate 4, the side wall outer plate reinforcing plate 50, the interior trim panel support 51 and the bunk light support 52 in the prior art, therefore, the side wall outer plate reinforcing plate 50 is arranged to include a first reinforcing plate 500 and a second reinforcing plate 501, and there is a gap between the first reinforcing plate 500 and the second reinforcing plate 501 in the cab height direction; the interior trim panel support 51 is arranged to include a first support body 510 and a second support body 511, and there is a gap between the first support body 510 and the second support body 511 in the cab height direction. Specifically, as shown in Figure 1 and Figure 2 shown, in the cab length direction, the side wall outer plate reinforcing plate 50, the interior trim panel support 51 and the bunk light support 52 are all connected with the B-pillar inner plate 3 and the C-pillar inner plate 4, as shown in Figure 3 , the side wall outer plate reinforcing plate 50, the interior trim panel support 51 and the bunk light support 52 need to add the bevel plate 53 therebetween, and in the cab width direction, the side wall outer plate reinforcing plate 50 and the interior trim panel support 51 have a part of overlap, therefore, on the basis of not affecting the arrangement of other structures in the cab, the part of the side wall outer plate reinforcing plate 50 overlapping with the interior trim panel support 51 is cancelled, so as to offset the added bevel plate 53.

[0050] Therefore, the existing side wall outer plate reinforcing plate 50 structure is changed, the side wall outer plate reinforcing plate 50 in the application includes a first reinforcing plate 500 and a second reinforcing plate 501, and a gap is arranged between the first reinforcing plate 500 and the second reinforcing plate 501; the existing interior trim panel support 51 structure is changed, the interior trim panel support 51 in the application includes a first support body 510 and a second support body 511, and a gap is arranged between the first support body 510 and the second support body 511. The first reinforcing plate 500, the second reinforcing plate 501, the first support body 510 and the second support body 511 are connected to each other through the inclined plate 53.

[0051] Further, the first reinforcing plate 500, the second reinforcing plate 501, the first support body 510 and the second support body 511 are arranged as follows: the first support body 510 is located between the first reinforcing plate 500 and the second reinforcing plate 501, and the second reinforcing plate 501 is located between the first support body 510 and the second support body 511. Among them, along the cab height direction, the first reinforcing plate 500, the second reinforcing plate 501, the first support body 510 and the second support body 511 are vertically arranged, and the inclined plate 53 is inclinedly arranged along the cab width direction. The first reinforcing plate 500 is connected to the first support body 510 through an inclined plate 53, and along the cab height direction, the first support body 510 is located at the top of the first reinforcing plate 500; the first support body 510 is connected to the second reinforcing plate 501 through an inclined plate 53, and along the cab height direction, the second reinforcing plate 501 is located at the top of the first support body 510; the second reinforcing plate 501 is connected to the second support body 511 through an inclined plate 53, and along the cab height direction, the second support body 511 is located at the top of the second reinforcing plate 501. The first reinforcing plate 500 and the second reinforcing plate 501 are located on the same side of the inclined plate 53, the first support body 510 and the second support body 511 are located on the same side of the inclined plate 53; the first reinforcing plate 500, the second reinforcing plate 501, the first support body 510 and the second support body 511 are located on different sides of the inclined plate 53. And along the cab height direction, the bunk lamp support 52 is arranged at the bottom of the second support body 511, and the bunk lamp support 52 and the second support body 511 are also connected by an inclined plate 53, and the bunk lamp support 52 is vertically arranged along the cab height direction, so the second reinforcing plate 501 is connected to the second support body 511 through two inclined plates 53 and the bunk lamp support 52.

[0052] Further, in order to further reduce the weight of the side wall structure, the B pillar inner panel 3, the C pillar inner panel 4 and the fusion panel 5 have the same thickness. The same thickness here means that, on the basis of the existing scheme and under the condition of ensuring the safety performance of the automobile, the thickness of some components is reduced, so that the thickness of the B pillar inner panel 3, the C pillar inner panel 4 and the fusion panel 5 is consistent. In order to make the description clearer, the following is an example: the thickness of the existing B pillar inner panel 3, the C pillar inner panel 4 and the side wall outer panel reinforcement 50 is generally 0.8 mm, and the thickness of the interior panel support 51 and the bed lamp support 52 is generally 1.5 mm. In this application, the thickness of the B pillar inner panel 3, the C pillar inner panel 4, the side wall outer panel reinforcement 50, the interior panel support 51 and the bed lamp support 52 is uniformly 0.8 mm. The thickness of the interior panel support 51 and the bed lamp support 52 is reduced, so that the weight of the side wall structure is reduced.

[0053] Further, in order to make up for the problem of insufficient local rigidity caused by the reduction of the thickness of some components, the fusion panel 5 is connected with a reinforcing rib 55 at a position where the local rigidity is insufficient, for example: if the thickness of the interior panel support 51 and the bed lamp support 52 is reduced, the local rigidity of the interior panel support 51 and the bed lamp support 52 needs to be enhanced by adding the reinforcing rib 55. At the same time, the reinforcing rib 55 is arranged around the mounting point 12 without affecting the mounting and connection of the fusion panel 5 and other structures of the cab. On this basis, since the reinforcing rib 55 is arranged at the position where the local rigidity of the fusion panel 5 is insufficient, the weight of the reinforcing rib 55 is made up, and under the condition of ensuring the safety performance of the automobile, the weight-reducing hole 54 is arranged on the fusion panel 5, and the weight-reducing hole 54 can be arranged between two reinforcing ribs 55.
