The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 9, the aluminum honeycomb and aluminum plate splicing cab is schematically shown to comprise a front aluminum plate module 1, a cab framework 2, a roof aluminum honeycomb module 3, a side wall aluminum honeycomb module 4, a roof camber beam 5 and a roof side beam 6.

In the embodiment of the present application, the front-end aluminum plate module 1 is provided at the front end of the cab skeleton 2.

The roof aluminum honeycomb module 3 is arranged at the top end of the cab framework 2.

The side wall aluminum honeycomb modules 4 are arranged on two sides of the cab framework 2, wherein the front end aluminum plate module 1 and the roof aluminum honeycomb module 3 are connected into a whole through a roof camber beam 5 arranged on the top end of the cab framework 2, and two sides of the front end aluminum plate module 1 are respectively connected with the side wall aluminum honeycomb modules 4 on the corresponding sides into a whole through roof side edge beams 6 arranged on the roof camber beam 5. Specifically, the aluminum honeycomb and aluminum plate splicing cab is divided into four parts, namely a front-end aluminum plate module 1, a cab framework 2, a roof aluminum honeycomb module 3 and a side wall aluminum honeycomb module 4 according to the appearance commonality of the cab, relatively fixed interface structures are arranged among the four parts, and the interface structures comprise roof camber beams 5 and roof side beams 6, namely, the front-end aluminum plate module 1 and the roof aluminum honeycomb module 3 are connected into a whole through the roof camber beams 5 arranged at the top end of the cab framework 2, meanwhile, two sides of the front-end aluminum plate module 1 are respectively connected with the side wall aluminum honeycomb module 4 at the corresponding side through the roof camber beams 6 arranged on the roof camber beams 5, and all the parts can be used as independent modules under the condition that the interface positions are kept unchanged, so that the front-end aluminum plate module 1 in the newly designed vehicle model, One or more of the cab framework 2, the roof aluminum honeycomb module 3 and the side wall aluminum honeycomb module 4 are the same as those of the existing vehicle type, can be directly used, have good universality, and only need to redesign different parts, thereby greatly reducing the production design period and improving the production efficiency. In addition, when one or more modules are damaged, the same modules among different vehicle types can be replaced mutually, so that the storage space and the maintenance time are greatly saved, and meanwhile, the economic cost is also saved.

It should be noted that the front aluminum plate module 1 is made of an aluminum plate, the roof aluminum honeycomb module 3 is formed by splicing a plurality of aluminum honeycomb plates 32, and the side wall aluminum honeycomb module 4 is also formed by splicing a plurality of aluminum honeycomb plates 32.

The roof camber beam 5 and the roof side beam 6 are both hollow sections, so that the overall weight of the cab can be reduced. Two roof side rails 6 are provided, and each roof side rail 6 is welded to the roof bow 5 on the corresponding side.

The aluminum honeycomb and aluminum plate spliced cab further comprises a skirt board 10, wherein the skirt board 10 is made of glass steel materials and can be installed on an underframe at the end part of the cab through bolts as a single module.

As shown in fig. 3 and 4, in a preferred embodiment of the present application, the roof bow 5 and the roof side rail 6 each include: a connecting structure body 50, on the upper surface of which connecting structure body 50 is respectively configured a first shoulder 51 for connecting the aluminum honeycomb panel 32 in the roof aluminum honeycomb module 3 or the side wall aluminum honeycomb module 4 and a second shoulder 52 for connecting the aluminum panel 11 in the front aluminum panel module 1, the longitudinal height difference between the upper end surface of the first shoulder 51 and the upper end surface of the second shoulder 52 being equal to the longitudinal thickness difference between the aluminum panel 11 and the aluminum honeycomb panel 32.

The first supporting member 60 is disposed on one side of the connecting structure body 50 and extends in a direction away from the connecting structure body 50, and the first supporting member 60 is located below the first shoulder 51 for supporting the aluminum honeycomb panel 32. Specifically, since the connection structure body 50 is additionally provided and the first shoulder 51 and the second shoulder 52 are respectively configured on the upper surface of the connection structure body 50, and the first shoulder 51 is used for connecting the aluminum honeycomb panel 32 and the second shoulder 52 is used for connecting the aluminum plate 11, it is possible to realize that the aluminum honeycomb panel 32 and the aluminum plate 11 having different thicknesses are connected, and the contact area between the first shoulder 51 and the aluminum honeycomb panel 32 and the contact area between the second shoulder 52 and the aluminum plate 11 are not too large, so that the welding amount is not large at the time of welding, and the welding is also convenient.

Since the honeycomb core of the aluminum honeycomb panel 32 is often softer and thus does not have a good bearing force at all, in order to achieve a good connection between the aluminum honeycomb panel 32 and the connecting structure body 50, it is common to overlap the upper plate of the aluminum honeycomb panel 32 on the first shoulder 51 and then fixedly connect the upper plate to the upper end face of the first shoulder 51. Since the thickness of the upper layer tends to be thin, however, in particular, the thickness is generally preferably 2 mm, in this case, by additionally providing the first supporting member 60 such that the first supporting member 60 is disposed at one side of the connecting structure body 50 and extends in a direction away from the connecting structure body 50, at the same time, the first support member 60 is positioned below the first shoulder 51 for carrying the aluminum honeycomb panel 32, so that, since the first support member 60 contacts the lower surface of the aluminum honeycomb panel 32, the contact area therebetween is increased, a better upward supporting force can be provided to the aluminum honeycomb panel 32, thereby effectively improving the connection strength between the aluminum honeycomb panel 32 and the first shoulder 51 of the connecting structure body 50, avoiding the aluminum honeycomb panel 32 from being damaged by gravity under the condition of no stress support, so that the connection portion between the aluminum honeycomb panel 32 and the first shoulder 51 is broken.

It is thus clear that the connection structure of this application has also regarded as bearing stress point, therefore, atress parts such as partial cab hanger all can weld in this connection structure's bottom, avoids direct welding on aluminum honeycomb panel 32 and aluminum plate 11 to bearing capacity has been improved.

In addition, it should be noted that, by making the longitudinal height difference between the upper end surface of the first shoulder 51 and the upper end surface of the second shoulder 52 equal to the longitudinal thickness difference between the aluminum plate 11 and the aluminum honeycomb plate 32, the welding defect and deformation at the splicing position between the aluminum honeycomb plate 32 and the aluminum plate 11 are effectively solved, and the reliability and the aesthetic property of the welding between the aluminum honeycomb plate 32 and the aluminum plate 11 are ensured.

In another preferred embodiment of the present application, as shown in fig. 3 and 4, a first welding site for welding one end of the upper plate of the aluminum honeycomb panel 32 to the first shoulder 51 is configured on the first shoulder 51. The first welding position is arranged such that one end of the upper plate of the aluminum honeycomb panel 32 is overlapped on the first welding position of the first shoulder 51 and is welded with the upper end surface of the first shoulder 51 into a whole.

The "first welding site" refers to an upper plane of the first horizontal portion 511 as described below.

In another preferred embodiment of the present application, as shown in fig. 3 and 4, the first shoulder 51 comprises a first horizontal portion 511 and a first inclined portion 512 connected to the first horizontal portion 511, wherein a first angle a is formed between the first horizontal portion 511 and the first inclined portion 512. Wherein, the first included angle A can be in the range of 125-145 degrees. After one end of the upper plate of the aluminum honeycomb panel 32 is lapped on the first horizontal portion 511, a first bevel 513 is formed between the side end surface of the upper plate facing the first inclined portion 512 and the first inclined portion 512. The included angle b of the first bevel 513 is 35-55 degrees.

The first bevel 513 is provided to provide a welding site for firmly connecting the aluminum honeycomb panel 32 and the connection structure body 50.

In a preferred embodiment of the present application, as shown in fig. 3, the second shoulder 52 is arranged facing away from the first shoulder 51, and a second welding site for welding one end of the aluminum plate 11 to the second shoulder 52 is formed on the second shoulder 52. Specifically, one end of the aluminum plate 11 is lapped on the second welding position of the second shoulder 52, so that the position arrangement between the aluminum plate 11 and the connecting structure body 50 is realized, and then the fixed connection between the connecting structure body 50 and the aluminum plate 11 is realized by adopting a welding mode.

The "second bonding site" refers to an upper plane of the second horizontal portion 521 as described below.

In a further preferred embodiment of the application, the second shoulder 52 comprises a second horizontal portion 521 and a second inclined portion 522 connected to the second horizontal portion 521, wherein a second angle B is formed between the second horizontal portion 521 and the second inclined portion 522. Wherein, the second included angle B can be in the range of 125-145 degrees. After one end of the aluminum plate 11 is lapped on the second horizontal portion 521, a second bevel 523 is formed between a side end surface of the aluminum plate 11 facing the second inclined portion 522 and the second inclined portion 522. The included angle c of the second bevel 523 is 35-55 degrees.

The second bevel 523 is provided to provide a welding position for firmly connecting the aluminum plate 11 and the connection structure body 50.

In a preferred embodiment, the interior of the connecting structure body 50 is a hollow structure, and the interior of the connecting structure body 50 is designed to be a hollow structure, so that the connecting structure body has the advantages of light weight and weight reduction while ensuring better supporting strength and structural strength.

The first support member 60 includes a support plate, a support rib, or a support post. It should be noted that the supporting plate, the supporting rib or the supporting column can be fixedly installed on one side of the connecting structure body 50 by welding.

It will be appreciated that to ensure that the first support member 60 can provide a good support for the aluminum honeycomb panel 32, the first support member 60 is preferably disposed horizontally.

In another preferred embodiment, the thickness of the first support member 60 ranges from 2 to 5 times the thickness of the upper deck of the aluminum honeycomb panel 32. Specifically, the size range of the thickness H of the first supporting part 60 is controlled to be 2 times to 5 times of the thickness D of the upper layer of the aluminum honeycomb panel 32, so that the first supporting part 60 can have a reasonable thickness range, and the first supporting part 60 has good structural strength, further, the first supporting part 60 can have good supporting strength for the aluminum honeycomb panel 32, and the situation that the first supporting part 60 is bent and deformed or damaged downwards under the condition of being in a long-term stress is avoided.

In another preferred embodiment of the present application, the first support member 60 has an extension length ranging from 5 to 10 times the thickness of the upper deck of the aluminum honeycomb panel 32. It should be noted that the extension length L of the first support member 60 depends on the thickness D of the upper deck of the aluminum honeycomb panel 32, and the greater the thickness D of the upper deck, the longer the extension length L of the first support member 60. Specifically, the size range of the extension length L of the first supporting component 60 is 5 times to 10 times of the thickness D of the upper deck of the aluminum honeycomb panel 32, so that the first supporting component 60 can have a reasonable extension length, the first supporting component can well support and bear the aluminum honeycomb panel 32, the extension length of the first supporting component 60 is prevented from being insufficient, and the supporting strength of the first supporting component 60 to the aluminum honeycomb panel 32 is insufficient.

As shown in fig. 3 and 4, in a preferred embodiment of the present application, the connecting structure body 50 further includes a first projection 53 disposed between the first shoulder 51 and the second shoulder 52. The first projecting portion 53 is provided for the purpose of separating the first shoulder 51 and the second shoulder 52 well, and preventing the welding strength from being reduced due to an excessively small distance therebetween.

It should be noted that, after the upper plate of the aluminum honeycomb panel 32 is overlapped on the first shoulder 51 and the aluminum plate 11 is overlapped on the second shoulder 52, the upper surface of the upper plate, the upper surface of the first protruding portion 53 and the upper surface of the aluminum plate 11 are all flush, so that the aesthetic property of the aluminum honeycomb panel 32, the aluminum plate 11 and the connecting structure body 50 after connection is ensured.

In another embodiment, a first fillet weld site is configured on the first support member 60 for welding with the lower deck of the aluminum honeycomb panel 32. Specifically, the lower end of the aluminum honeycomb panel 32 is overlapped on the first fillet welding position of the first supporting member 60 and welded with the first supporting member 60 into a whole in a fillet welding manner. It should be noted that, by using the fillet welding connection method, the connection strength between the first support member 60 and the aluminum honeycomb panel 32 can be effectively enhanced, so that the first support member 60 is more firmly fixed and mounted, thereby providing a sufficient supporting force for the aluminum honeycomb panel 32.

The "first fillet welded portion" refers to a portion where the upper end surface of the first support member 60 is engaged with the left end surface shown in fig. 3, and this portion is in contact with the right lower end surface of the aluminum honeycomb panel 32.

In another preferred embodiment of the present application, a second fillet welding site is formed at a portion of the second horizontal portion 521, which is in contact with the aluminum plate 11. It should be noted that the second fillet welding position is used for providing a fillet welding position, that is, the second horizontal portion 521 and the aluminum plate 11 are connected into a whole in a fillet welding manner, so that the connection strength between the aluminum plate 11 and the second horizontal portion 521 can be effectively improved, and the aluminum plate 11 can be connected with the connection structure body 50 well.

The "second fillet welding site" refers to a site where the upper end surface of the second horizontal portion 521 is in contact with the side end surface (the right end surface shown in fig. 3) thereof.

As shown in fig. 5 to 9, in a preferred embodiment of the present application, the roof aluminum honeycomb module 3 includes at least one roof connecting beam 31, and the at least one roof connecting beam 31 is provided on the roof bow 5.

At least two aluminum honeycomb plates 32, one roof connecting beam 31 is arranged between every two aluminum honeycomb plates 32, and each aluminum honeycomb plate 32 is fixedly connected with the left side or the right side of the roof connecting beam 31. It should be noted that the aluminum honeycomb panel 32 is a conventional structure, and generally includes an upper panel, a lower panel, and a honeycomb core sandwiched between the upper panel and the lower panel.

Specifically, because the aluminum honeycomb panel 32 has high structural strength and good rigidity, when the aluminum honeycomb panel is applied to the roof aluminum honeycomb module 3, the number of the plate beams can be reduced to a certain extent, so that the weight of the cab roof is reduced, and the cab roof has the advantages of light weight and good manufacturability.

In addition, because the structural strength of the cab roof is effectively enhanced by additionally arranging the aluminum honeycomb panel 32, the number of the plate beams can be properly reduced, and the welding amount is greatly reduced along with the reduction of the number of the plate beams, so that the manufacturing difficulty of the cab roof is effectively simplified, the complexity of the manufacturing process of the cab roof is reduced, and the production efficiency of the cab roof is improved.

The roof connecting rail 31 is configured to have a hollow structure inside. In this way, since the roof connecting beam 31 has a hollow structure inside, the weight of the cab roof can be effectively reduced while ensuring the structural strength, the support strength, and the load bearing strength, so that the cab roof meets the requirement of light weight.

In the present embodiment, the roof connecting rail 31 has a cross-sectional shape resembling a letter "convex".

It should be noted that the roof rail 31 is preferably made of a hollow profile.

In a specific embodiment of the present application, the aluminum honeycomb panel 32 disposed on the left side of the roof connecting beam 31 is a first aluminum honeycomb panel 321, the aluminum honeycomb panel 32 disposed on the right side of the roof connecting beam 31 is a second aluminum honeycomb panel 322, a second protrusion 311 is formed on the upper surface of the roof connecting beam 31, and third shoulders 312 for bearing the first aluminum honeycomb panel 321 and fourth shoulders 313 for bearing the second aluminum honeycomb panel 322 are formed on the left and right sides of the second protrusion 311, respectively.

It should be noted that the third shoulder 312 is provided to provide a better supporting function for the whole first aluminum honeycomb panel 321, so that it can be better fixedly connected to the corresponding side of the roof connecting beam 31.

Similarly, the fourth shoulder 313 provides a better support for the second aluminum honeycomb panel 322 as a whole, so that it can be better fixedly connected to the corresponding side of the roof connecting beam 31.

The roof connecting beam 31 and the first aluminum honeycomb panel 321 and the second aluminum honeycomb panel 322 respectively disposed on the left and right sides of the roof connecting beam 31 together constitute a basic splice module of the cab roof. The number of the basic splicing modules can be specifically determined according to the areas of the roofs of the cabs of vehicles of different models, namely, the number of the basic splicing modules can be 1, 2, 3 or more than 3.

As shown in fig. 7 and 8, the upper end surface of the third shoulder 312 is flush with the upper end surface of the fourth shoulder 313. Specifically, when the first aluminum honeycomb panel 321 is overlapped on the upper end surface of the third shoulder 312 and the second aluminum honeycomb panel 322 is overlapped on the upper end surface of the fourth shoulder 313, the upper end surface of the upper plate of the first aluminum honeycomb panel 321 is flush with the upper end surface of the fourth shoulder 313, so that the upper end surface of the upper plate of the second aluminum honeycomb panel 322 is ensured to be flush with the upper end surface of the upper plate of the first aluminum honeycomb panel 321. Therefore, smooth connection of the top surface of the aluminum honeycomb module of the cab roof can be ensured, and the condition that welding effect is influenced due to height dislocation is avoided, so that the overall attractiveness of the cab roof structure is effectively ensured.
