In addition, the present application provides examples of various specific processes and materials, but those skilled in the art can realize the application of other processes and / or the use of other materials.

[0019] The present application will be described below in combination with the drawings and with reference to specific embodiments: The cab rear support, fuel tank support and upper-mounted support front support are independently and discretely arranged on the frame of the off-road vehicle, but there are many parts, complex assembly, large space occupation, which can easily cause resource waste, cost increase, installation inconvenience and other problems.

[0020] Therefore, the embodiments of the present application provide an integrated support for super heavy off-road vehicles, which aims to at least partially solve the technical problems of the super heavy off-road vehicle, such as the plurality of fixed structure parts of the cab rear support, fuel tank support and upper-mounted support front support, complex assembly, large space occupation.

[0021] Referring to Figure 1 In some embodiments, the integrated support for super heavy off-road vehicles is configured to adapt to the integrated structure of the cab support, the fuel tank support and the upper-mounted support, which can compactly fix the cab support, the fuel tank and the upper-mounted structure, and ensure the reliability and stability of the fixing state of the above three fixed main bodies through structural arrangement.

[0022] The integrated support for super heavy off-road vehicles includes a main mounting plate 1, an ear 2, a vertical plate 3, a partition plate 4, a connection plate 5, a secondary mounting plate 6, a stiffener 7 and a support plate 8.

[0023] The main mounting plate 1 is configured as a force bearing base of the integrated support for the super heavy off-road vehicle, for mounting and supporting other components. The main mounting plate 1 is a special-shaped bent plate member, which is bent and formed by a plate member, and has a first main plate body 11 and a second main plate body 12 divided along a bending boundary line. That is, the main mounting plate 1 is a bent and formed three-dimensional member, so that the form stability and support reliability of the main mounting plate 1 can be strengthened by mutual support of the first main plate body 11 and the second main plate body 12. And a through hole 12a is formed in the second main plate body 12, and the middle body of the lug 2 is embedded in the through hole 12a, so as to fix the lug 2 based on the main mounting plate 1.

[0024] The lug 2 is a fastener for fixing the rear part of the cab, which is inserted into the through hole 12a and fixedly connected with the second main plate body 12, so as to stably fix the lug 2 on the second plate body 12, and then stably and reliably fix the cab.

[0025] The upright plate 3 is configured as a support strengthening member, which is arranged between the first main plate body 11 and the second main plate body 12, i.e. in the corner area, and is fixedly connected with the first main plate body 11 and the second main plate body 12, so as to strengthen the form stability and force bearing reliability of the main mounting plate 1. The upright plate 3 is also fixedly connected with the lug 2, so as to strengthen the fixing reliability of the lug 2. The upright plate 3 forms a support structure together with other components, which can enhance the overall rigidity of the support.

[0026] The partition plate 4 is configured as a support strengthening member, which is arranged between the upright plate 3 and the lug 2, and is fixedly connected with the upright plate 3, the lug 2 and the first main plate body 11, so as to further strengthen the fixing reliability of the lug 2 and the connection strength between the upright plate 3 and the first main plate body 11. That is, the partition plate 7, the upright plate 3 and the lug 2 are connected in a closed structure to increase the strength and rigidity of the cab mounting part, limit deformation, and ensure the stability and safety of the cab.

[0027] The connecting plate 5 is configured as a support strengthening member, which is arranged between the upright plate 3, the first main plate body 11 and the partition plate 4, and is fixedly connected with the upright plate 3 and the partition plate 4, so as to further strengthen the connection reliability between the main mounting plate 1, the lug 2, the partition plate 4 and the upright plate 3, and improve the support stability and force bearing performance. That is, a three-dimensional frame structure is formed to provide a stable and reliable high-strength support structure for the lug 2, so as to stably mount and fix the rear part of the cab.

[0028] The secondary mounting plate 6 is configured as an installation support structure of the oil tank and the upper mounting structure, and the primary mounting plate 1 is a profiled bent plate member, which is bent and formed by a plate member, and has a first secondary plate body 61 and a second secondary plate body 62 divided along a bending boundary line. That is, the secondary mounting plate 6 is a three-dimensional profiled member bent and formed, so as to strengthen the profile stability and support reliability of the secondary mounting plate 6 through mutual support of the first secondary plate body 61 and the second secondary plate body 62. Meanwhile, the first secondary plate body 61 and the second secondary plate body 62 are respectively configured as support structures of the upper mounting structure and the oil tank. The first secondary plate body 61 and the second secondary plate body 62 are provided with mounting structures for mounting of the upper mounting structure and the oil tank.

[0029] The first secondary plate body 61 is located between the vertical plate 3 and the first primary plate body 11, and is fixedly connected to the vertical plate 3 and the first primary plate body 11. The second secondary plate body 62 is located with the vertical plate 3, so as to form a three-dimensional box frame plate structure and ensure the strength of the structure.

[0030] The reinforcing rib 7 is configured as a local reinforcing member, and is arranged between the vertical plate 3 and the first secondary plate body 61. The reinforcing rib 7 is fixedly connected to the vertical plate 3 and the first secondary plate body 61, so as to ensure the relative position and posture stability of the first secondary plate body 61 and the vertical plate 3. Generally, the reinforcing rib 7 can be arranged at the connecting area of the vertical plate 3 and the first secondary plate body 61, so as to enhance the strength of the overall structure and avoid stress concentration.

[0031] The support plate 8 is configured as a reinforcing structure of the secondary mounting plate 6, and is arranged between the vertical plate 3, the first primary plate body 11, the first secondary plate body 61 and the second secondary plate body 62. The support plate 8 is fixedly connected to the first primary plate body 11, the first secondary plate body 61 and the second secondary plate body 62, so as to increase the longitudinal rigidity of the fuel tank and the upper mounting bracket mounting part to a certain extent.

[0032] In some embodiments, in order to improve the connection strength and reliability of the vertical plate 3 and the primary mounting plate 1, a first bending part 121 can be arranged at an end of the second primary plate body 12 away from the first primary plate body 11. The bending direction of the first bending part 121 is towards the vertical plate 3, and the first bending part 121 is fixedly connected to the vertical plate 3.

[0033] That is, the first bending part 121, the second main plate body 12 and the first main plate body 11 form a U-shaped slot 12b, the end of the stand plate 3 is embedded in the U-shaped slot 12b and is fixedly connected with the first bending part 121, the second main plate body 12 and the first main plate body 11, and is stably connected from the left and right sides and the support direction of the stand plate 3, thereby improving the support reliability and impact resistance, and being particularly suitable for the running impact environment of super heavy off-road vehicles.

[0034] Generally, the first bending part 121 can be partially bent by the second main plate body 12, and is generally bent at 90 degrees, so as to adjust the stress distribution, improve the limiting support ability of the first bending part 121 to the stand plate 3, and maintain the stable support shape under impact.

[0035] In some embodiments, the first main plate body 11, the second main plate body 12 and the first bending part 121 are generally bent into an L-shaped piece, and the stand plate 3 is also generally orthogonal to the first bending part 121, the second main plate body 12 and the first main plate body 11, so that the two main bodies connected in the stand plate 3, the first bending part 121, the second main plate body 12 and the first main plate body 11 are generally orthogonal, which helps to maintain the stability and impact resistance of the support shape.

[0036] In some embodiments, considering that the lug 2 is embedded in the through hole 12a, in order to improve the support strength and stability of the second main plate body 12, the stand plate 3 can be arranged in parallel on both sides of the lug, thereby balancing the support of the lug 2.

[0037] That is, the two stand plates 3 clamp the lug 2 to form an I-shaped support shape, thereby dispersing the pressure borne by the lug 2 to the orthogonal second main plate body 12 and the two stand plates 3, and achieving stable support.

[0038] In some embodiments, in order to facilitate assembly, the first bending part 121 can be shorter than the stand plate 3, and is only fixedly connected to part of the end of the stand plate 3, so as to lock the end of the stand plate 3.

[0039] In some embodiments, the stand plate 3, the first bending part 121, the second main plate body 12, the lug and the first main plate body 11 can be respectively welded to form an integral piece, thereby improving the connection strength.

[0040] In some embodiments, the second main plate body 12 and the first main plate body 11 are connected at a second bending portion 122, which is bent towards the vertical plate 3, to form a recessed portion 12c, thereby avoiding other structures at the rear of the cab.

[0041] It is worth mentioning that the second bending portion 122 is bent at a right angle, and the second bending portion 122 is also supported on one side of the vertical plate 3 to ensure the reliability of the structure.

[0042] In some embodiments, the partition plate 4 is also arranged between the two vertical plates 3 and is orthogonally connected to the two vertical plates 3 and the lug 2, thereby enhancing the support reliability of the two vertical plates 3.

[0043] In some embodiments, the connecting plate 5 is arranged in an L shape, and the L-shaped edge of the connecting plate 5 is connected to the two vertical plates 3, thereby enhancing the support of the vertical plate 3.

[0044] Typically, the L-shaped edge of the connecting plate 5 is welded to the edge of the vertical plate 3, forming a substantially closed edge, thereby improving the support reliability.

[0045] In some embodiments, the main mounting plate 1, the lug 2, the vertical plate 3, the partition plate 4, and the connecting plate 5 are connected by welding.

[0046] In some embodiments, the angle between the second main plate body 12 and the first main plate body 11 is greater than 90 degrees.

[0047] It is worth mentioning that, based on the horizontal arrangement of the second main plate body 12, the lug 2 is vertically arranged and protrudes from the second main plate body 12. The first main plate body 11, the vertical plate 3, the partition plate 4, and the connecting plate 5 are located below the second main plate body 12, forming a three-dimensional frame support structure of the lug 2, achieving compact and lightweight support.

[0048] The main mounting plate 1, the two vertical plates 3, the partition plate 4, and the L-shaped connecting plate form a box frame, which has good support reliability.

[0049] In some embodiments, the number of lugs 2 can be two, to achieve a double support structure.

[0050] In some embodiments, in consideration of the fact that the secondary mounting plate 6 is a bent piece, in order to improve the support reliability of the secondary mounting plate 6, the support plate 8 can be welded on the first main plate body 11, the first secondary plate body 61 and the second secondary plate body 62, achieving stable and high-strength support.

[0051] It is worth mentioning that, with the second main plate body 12 horizontally arranged as the reference, the first secondary plate body 61 is arranged horizontally, the second secondary plate body 62 is arranged vertically, the support plate 8 is arranged vertically, and the support plate 8 is welded with the first secondary plate body 61, the second secondary plate body 62 and the first main plate body 11 substantially orthogonally, to substantially form a box frame structure, improving the support reliability and impact resistance.

[0052] In some embodiments, the number of the support plate 8 can be set to be multiple, and the support plate 8 is arranged substantially in parallel with the vertical plate 3.

[0053] In some embodiments, in order to improve the support reliability, the reinforcing rib 7 adopts a box frame-shaped three-dimensional reinforcing piece.

[0054] In some embodiments, in order to lighten the integrated support for the super-heavy off-road vehicle, a lightening hole 9a can be formed in one or more of the first main plate body 11, the vertical plate 3, the secondary mounting plate 6, the reinforcing rib 7, the support plate 8, the partition plate 4 and the connecting plate 5.

[0055] Generally, in order to facilitate the installation of the oil tank and the upper-mounted structure, an assembly screw hole 9b can be arranged on the secondary mounting plate 6 and the first main plate body 11 respectively.
