[0024] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0025] Reference below Figure 1-Figure 2 The connecting bracket 1 of the vehicle frame 100 according to the embodiment of the utility model is described. On the basis of ensuring the overall structural strength, the number of connecting plates 11 can be increased, so that the individual connecting plates 11 are smaller in size and lighter in weight, thereby solving the problem that the connecting bracket 1 of the vehicle frame 100 is difficult to disassemble and assemble and difficult to connect to the upper body.

[0026] Combination Figure 1-Figure 2 As shown, the connecting bracket 1 of the vehicle frame 100 according to the first embodiment of the utility model comprises a plurality of connecting plates 11. Among them, the plurality of connecting plates 11 can all play the role of connecting and fixing the support to the structure connected thereto.

[0027] Specifically, a plurality of connecting plates 11 are arranged at intervals along the longitudinal direction of the frame 100 , and each connecting plate 11 is provided with an upper connecting portion 111 and a lower connecting portion 112 arranged vertically at intervals, the upper connecting portion 111 is used to connect to the sub-frame 100 or the upper fixing part, and the lower connecting portion 112 is used to connect to the longitudinal beam 101 of the frame 100 .

[0028] In detail, a plurality of connecting plates 11 are arranged at intervals in the longitudinal direction of the frame 100 (that is, the front-to-rear direction when the vehicle is traveling), so that the frame 100 can form a plurality of connecting force-bearing positions in the longitudinal direction, increase the number of connecting force-bearing paths between the connecting bracket 1 and the frame 100, and thus improve the connection strength between the connecting bracket 1 and the frame 100; each connecting plate 11 is arranged at intervals with an upper connecting portion 111 and a lower connecting portion 112 in the vertical direction (that is, the up-down direction), so that each connecting plate 11 forms a partition connection effect, and such an arrangement facilitates the upper connecting portion 111 and the lower connecting portion 112 to establish a mutually connected and installed relationship with the corresponding structure according to the space layout requirements, and can also establish an indirect connection relationship between the structures respectively connected to the upper connecting portion 111 and the lower connecting portion 112 through the connecting plate 11, so that they become a whole, thereby improving the overall structural consistency and structural reliability of the frame 100. In addition, the connecting plate 11 can also increase the weight or spatial mode of the longitudinal beam 101 of the frame 100 and the sub-frame 100 located above the longitudinal beam 101 of the frame 100 , thereby enhancing the structural strength and bending and torsional rigidity of each other.

[0029] Compared with the traditional one-piece connecting bracket (generally made of a whole piece of steel plate by laser cutting and punching, with a large mass, it is not convenient to align and install, and it is easy to deform due to its large area after assembly. Local deformation needs to be corrected as a whole when the upper body is connected, which is difficult to correct; it is also not easy to disassemble, that is, it is not easy to tighten during installation, not easy to disassemble when maintenance is required, and the assembly is affected by easy deformation when connected to the upper body), the embodiment of this case adopts a plurality of split connecting plates 11, which can be easily distributed according to the arrangement of the relevant structures on the longitudinal beam 101, thereby avoiding the need to cut the entire connecting plate specifically to match the longitudinal beam The outer contour of 101; it can also make the volume and mass of each connecting plate 11 smaller, which is convenient for users to take, disassemble and align, thereby improving the installation quality of the connecting bracket 1 and reducing the installation difficulty of the connecting bracket 1; it can also avoid the problem of difficulty in correction caused by the large area of ​​the connecting plate during installation (the larger the area, the easier it is to deform) (that is, the traditional whole connecting plate is easy to deform after assembly due to its large area, so the local deformation caused by its installation and connection needs to be corrected as a whole, which is difficult to correct), thereby facilitating assembly and disassembly and maintenance, thereby improving manufacturing efficiency and improving production efficiency.

[0030] Therefore, by providing the connecting bracket 1, the number of connecting plates 11 can be increased on the basis of ensuring the overall structural strength, so that the individual connecting plates 11 are smaller in size and lighter in weight, so that they are easy to pick up and align during assembly, thereby solving the problem that the connecting bracket 1 of the frame 100 is difficult to disassemble and assemble and difficult to connect to.

[0031] According to some optional embodiments of the present invention, combined with Figure 2 As shown, the lower connection portion 112 is configured with a plurality of first connection holes 1121, and the plurality of first connection holes 1121 are used to be connected to the longitudinal beam 101 through fasteners. For example, the fasteners may be bolts, but are not limited thereto.

[0032] Among them, a plurality of first connection holes 1121 arranged at intervals are constructed on the lower connection portion 112, so that a plurality of installation positions for fasteners to be connected to the longitudinal beam 101 can be provided, so that users can flexibly distribute the fastening connection positions of the fasteners according to the requirements of the connection positions, thereby improving the versatility and flexibility of the connecting plate 11 during assembly.

[0033] In addition, a plurality of connecting plates 11 may be respectively arranged on the longitudinal beams 101 spaced apart in the transverse direction (ie, the left-right direction).

[0034] Specifically, combined Figure 2As shown, a plurality of first connection holes 1121 are arranged in a matrix on the connection plate 11. It is understandable that such an arrangement can distribute external force and weight more evenly, reduce local stress concentration, and thus make the structure connected and installed using the first connection holes 1121 more stable; it can also ensure the precise matching of the first connection holes 1121 with the corresponding longitudinal beams 101, thereby improving the accuracy and efficiency of the assembly of the two, reducing installation errors and adjustment time; it can also facilitate the installation of the longitudinal beams 101 in different positions or directions of the connection plate 11, thereby increasing the connection versatility and adaptability of the connection plate 11; it can also simplify the design of production molds and assembly tools through this standardized matrix layout, thereby reducing manufacturing costs and improving assembly efficiency. For example, on an automated production line, a unified hole array is easier to locate and automatically assemble by a machine, thereby improving production efficiency.

[0035] Furthermore, combined with Figure 2 As shown, in each row of first connection holes 1121, a plurality of first connection holes 1121 are evenly spaced along the longitudinal direction of the frame 100. That is, along the longitudinal direction of the frame 100, a plurality of first connection holes 1121 are evenly spaced, so that the longitudinal intervals between the first connection holes 1121 can be unified, thereby making the arrangement of the plurality of first connection holes 1121 more regular and standardized, which is conducive to simplifying the production process and thus improving the manufacturing efficiency.

[0036] Specifically, combined Figure 2 As shown, in each column of first connection holes 1121, a plurality of first connection holes 1121 are arranged at intervals in the vertical direction, and the spacing between two adjacent first connection holes 1121 gradually increases from top to bottom. It can be understood that along the vertical direction, the spacing between two adjacent first connection holes 1121 increases from top to bottom, and such an arrangement can match the position of the connection holes on the longitudinal beam 101 (for example, the vertical spacing of the connection holes on the longitudinal beam of the existing heavy truck is a standardized value), so that the first connection holes 1121 on the connecting plate 11 can all smoothly correspond to the connection hole positions at different heights of the longitudinal beam 101, thereby ensuring the connection versatility of the connecting bracket 1.

[0037] According to some optional embodiments of the present invention, combined with Figure 2 As shown, the upper connecting portion 111 is configured with a second connecting hole 1111 , and the second connecting hole 1111 is located in the middle of the connecting plate 11 along the longitudinal direction of the vehicle frame 100 .

[0038] Among them, the second connection hole 1111 on the upper connection part 111 is mainly used to provide connection conditions with the subframe 100 or the upper mounting fixings above the longitudinal beam 101. In addition, the second connection hole 1111 is located in the middle of the connection plate 11 along the longitudinal direction of the frame 100. Such an arrangement can make the weight and stress at the upper connection part 111 be distributed more evenly, thereby reducing the distortion or deformation caused by eccentric loads (especially in equipment that carries heavy objects or bears dynamic loads), thereby maintaining the stability and balance of the overall structure; it can also more effectively absorb and disperse vibrations, reduce the vibration transmission generated when the vehicle is running, thereby reducing the noise level and improving the long-term durability of the connection bracket 1; and it can also minimize the impact of the opening on the overall structural strength, ensuring that the connection bracket 1 can still maintain sufficient rigidity and load-bearing capacity after installation and fixation.

[0039] Specifically, combined Figure 2 As shown, the second connection hole 1111 is constructed as a long strip hole, and the second connection hole 1111 extends in the longitudinal direction of the vehicle frame 100. It can be understood that such an arrangement can increase the opening area of ​​the second connection hole 1111, thereby facilitating the increase of the connection contact area between the upper connection portion 111 and the structure to which it is connected, thereby improving the connection reliability between the two. Among them, the second connection hole 1111 extends in the longitudinal direction of the vehicle, so that the opening size of the second connection hole 1111 in the longitudinal direction can be increased, thereby facilitating the increase of the longitudinal connection size of the connection portion and the structure to which it is connected, thereby improving the connection strength therebetween.

[0040] According to some optional embodiments of the present invention, combined with Figure 2 As shown, each connecting plate 11 is an integrally formed metal plate, and the weight of the connecting plate 11 is m, where m satisfies the relationship: 10KG≤m≤20KG.

[0041] Among them, each connecting plate 11 can be constructed as the same sheet structure, which is convenient for large-scale production of the connecting plates 11, thereby improving the versatility and production efficiency of the connecting plates 11. In addition, each connecting plate 11 adopts an integrated molding process, which can improve the overall structural properties and structural strength of the connecting plate 11 compared to the split assembly type connecting plate, thereby improving the structural reliability of the connecting plate 11; the connecting plate 11 is made of metal material, which has greater structural strength and rigidity, thus improving the structural reliability of the connecting plate 11.

[0042] In particular, the weight of the connecting plate 11 is relatively small, which can facilitate the user to carry out the pick-up and alignment actions when disassembling and repairing the connecting plate 11, thereby improving the assembly efficiency. For example, the weight m of the connecting plate 11 can be 10KG, 12KG, 14KG and 20KG, but is not limited thereto.

[0043] According to some optional embodiments of the present invention, combined with Figure 2 As shown, the connection plate 11 is formed with a plurality of chamfered portions 113 , and the plurality of chamfered portions 113 are arranged at intervals on the circumferential edge of the connection plate 11 .

[0044] Specifically, the chamfered portion 113 can remove burrs generated by machining on the edge of the connecting plate 11, thereby preventing the user from being cut by the sharp edge when touching or operating, and improving the safety of the user when using the connecting plate 11. In addition, multiple chamfered portions 113 are arranged at intervals on the circumferential edge of the connecting plate 11, which can effectively prevent the risk of the user being easily cut by the sharp edge of the connecting plate 11.

[0045] The vehicle according to the embodiment of the second aspect of the utility model includes a frame 100 and a connecting bracket 1 of the frame 100 of the above-mentioned embodiment, and the lower connecting portion 112 is connected to the longitudinal beam 101 of the frame 100. The vehicle with the connecting bracket 1 can improve the versatility and assembly convenience of the connecting bracket 1, and can also reduce costs, thereby improving the market competitiveness of the vehicle.
