[0037] like Figures 1 to 4 As shown, the present application provides a multifunctional rear suspension mechanism, including a mounting support plate 2, wherein the mounting support plate 2 includes:

[0038] A first support plate 21, the side wall of which is fixedly connected to the cab mounting support 1;

[0039] A second support plate 22, the second support plate 22 is arranged opposite to the first support plate 21, and the side wall of the second support plate 22 is fixedly connected to the cab mounting support 1;

[0040] A third support plate 23, the third support plate 23 is located between the first support plate 21 and the second support plate 22, the bottom of the third support plate 23 is connected to the longitudinal beam 3, and the two side walls of the third support plate 23 are respectively connected to the first support plate 21 and the second support plate 22;

[0041] It also includes a rear suspension support 4, which is connected to the frame beam and is connected to the mounting support plate 2 and / or the longitudinal beam 3.

[0042] This solution realizes the connection between the rear suspension assembly and the cab mounting support 1 by setting the first support plate 21, the third support plate 23 and the second support plate 22 connected in sequence, thereby realizing the matching between the longitudinal beam 3 and the cab mounting support 1, and at the same time realizes the connection with the rear suspension support 4 through the first support plate 21, the second support plate 22 and the third support plate 23, and the rear suspension support 4 is connected to the frame beam at the same time, thereby realizing the matching with the rear suspension support 4. The rear suspension support 4 is installed through the third support plate 23, that is, it realizes the connection between it and the longitudinal beam 3, thereby realizing the matching between the longitudinal beam 3 and the cab mounting support 1 and the fixation of the rear suspension mechanism.

[0043] In addition, in the present solution, a mounting support plate 2 is provided that matches the cab mounting support 1 and the rear suspension support 4, and the mounting support plate 2 is connected to the longitudinal beam 3. The mounting support plate 2 is used as an intermediate piece to meet the installation requirements of different types of frames. That is, through this solution, a set of connection structures can be used to meet the rear suspension assembly under different requirements.

[0044] It should be noted that a folded edge is provided at the top of the third support plate 23, and the folded edge is formed extending outward from the top of the third support plate 23, which is conducive to enhancing the structural strength of the third support plate 23, thereby further improving the stability of the installation support plate 2. The bottoms of the first support plate 21 and the second support plate 22 are provided with folded edges connected to the longitudinal beam 3.

[0045] In one embodiment, the first support plate 21 , the second support plate 22 and the third support plate 23 together form a cavity 24 , the bottom of the cab mounting support 1 is provided with an opening 11 communicating with the cavity 24 , and the mounting support plate 2 is provided with a mounting portion connected to the rear suspension support 4 .

[0046] In this way, the rear suspension support 4 does not need to be separately matched and fixed with the cab mounting support 1, but is directly limited in relative position with the longitudinal beam 3 through the third support plate 23. Its fixed position is located at the lower bottom surface of the rear part of the longitudinal beam 3, which is beneficial to the reduction of the vertical size of the rear suspension support 4, and its fixing structure and installation method are simpler, while achieving weight reduction.

[0047] like Figure 2 As shown, in one embodiment, the mounting portion includes a through hole 231 located on the third support plate 23, the rear suspension support 4 includes a pressure plate 41 located above the opening 11 and a connecting plate 42 fixed to the first support plate 21 and the second support plate 22, the connecting plate 42 extends vertically and a shock absorber 43 is provided at the extended end, and a fixing plate connected to the frame beam is provided at the bottom of the shock absorber 43.

[0048] This method can be used to cancel the locking mechanism on the basis of the rear suspension mechanism of a conventional fuel vehicle when the frame and cab of an ordinary new energy vehicle are not reversed. Specifically, the rear suspension support 4 is defined relative to the cab support through the connecting plate 42, and the bolt 6 is fixed through the cab mounting support 1, the first support plate 21 and the connecting plate 42, and the bolt 6 on the other side passes through the cab mounting support 1, the second support plate 22 and the connecting plate 42 for fixing, and the shock absorber 43 and the fixing plate are connected below the connecting plate 42, so as to define the relative position between the fixing plate and the cab mounting support 1 and the frame beam. In this method, the rear suspension support 4 can be connected to the end of the longitudinal beam 3 to improve the overall stability.

[0049] Furthermore, the shock absorber 43 includes a rubber sleeve 431 and a steel sleeve 432 . The steel sleeve 432 is fixedly sleeved on the rubber sleeve 431 . A connecting hole is provided in the rubber sleeve 431 and aligned with the connecting plate 42 . A fastener is provided through the connecting hole to fix the rubber sleeve 431 and the connecting plate 42 .

[0050] The steel sleeve 432 is wear-resistant and the rubber sleeve 431 is shock-absorbing, thereby ensuring the stability of the overall structure and the service life of the rear suspension mechanism.

[0051] As another example under the above implementation mode:

[0052] like Figure 3 As shown, a safety bolt 52 extending outward is provided between the connecting plate 42 and the shock absorber 43 , and the rear suspension mechanism also includes a locking mechanism connected to the cab mounting bracket, and a safety hook 53 cooperating with the safety bolt 52 is provided at the bottom of the locking mechanism.

[0053] In this embodiment, the rear suspension mechanism of this scheme is used for fuel-powered vehicles, and the cab flipping requirement can be achieved by cooperating with the locking mechanism. In this embodiment, the positioning plate 45 is further fixedly connected to the longitudinal beam 3 to improve the overall structural stability.

[0054] It is understandable that the locking mechanism in this solution is combined with the unlocking handle 51, and the locking mechanism and unlocking handle 51 of the cab of a fuel vehicle in the prior art can be applied, which will not be elaborated here.

[0055] In another embodiment:

[0056] like Figure 4 As shown, the rear suspension support 4 includes a shock absorbing assembly 44 fixed to the longitudinal beam 3 and a positioning plate 45 connecting the shock absorbing assembly 44 and the frame beam, and the shock absorbing assembly 44 is partially located in the cavity 24. The longitudinal beam 3 is provided with a positioning hole 31, and the positioning plate 45 is provided with a mounting opening 451 coaxial with the positioning hole 31. The shock absorbing assembly 44 includes a pressure block 445 located above the positioning hole 31 and a rubber block located below the positioning hole 31. The pressure block 445 and the rubber block are connected by fasteners, and the rubber block is fixed to the positioning plate 45.

[0057] In this embodiment, the rear suspension support 4 is arranged below the rear of the longitudinal beam 3 and is not directly fixedly connected to the cab mounting support 1. The overall vertical height of the rear suspension support 4 is small and the structure is simple, so that it is lightweight. The rear suspension mechanism in this embodiment is applied to the setting of a pure flat floor of the cab of a new energy vehicle frame. This type of vehicle has a larger local size change than conventional vehicles, and it is difficult to achieve connection using a traditional rear suspension mechanism. An installation support plate 2 and a rear suspension support 4 are set. The installation support plate 2 is divided into a first support plate 21, a second support plate 22 and a third support plate 23. Through the connection between the three and the connection with the cab mounting support 1 and the longitudinal beam 3, the height difference problem when the rear section of the longitudinal beam 3 is overlapped with the cab mounting support 1 is solved, and the fixed position of the longitudinal beam 3 is located between the installation support plate 2 and the rear suspension support 4, which ensures that the longitudinal beam 3 is balanced in force.

[0058] Furthermore, the rubber block passes through the mounting opening 451, which includes a first shock absorbing portion 441 located above the mounting opening 451 and a second shock absorbing portion 442 located below the mounting opening 451. The shock absorbing assembly 44 also includes a limiting tray 443 abutting the top surface of the positioning plate 45, and the first shock absorbing portion 441 is at least partially located in the limiting tray 443.

[0059] The first shock absorbing part 441 and the second shock absorbing part 442 are set as an integrated cylindrical setting to enhance the overall stability and shock absorbing effect. The inner wall of the limiting tray 443 is at least partially in contact with the outer wall of the first shock absorbing part 441, forming a limit for the first shock absorbing part 441 to avoid the position shift of the first shock absorbing part 441. When the first shock absorbing part 441 and the second shock absorbing part 442 are set as an integrated setting, the position shift of the rubber block as a whole can be avoided. It can be understood that the limiting tray 443 is enclosed by the outer wall of the first shock absorbing part 441. Since the first shock absorbing part 441 has a certain height in the vertical direction, the first shock absorbing part 441 described in this embodiment as being at least partially located in the limiting tray 443 refers to the vertical height, that is, the projection of the first shock absorbing part 441 in the horizontal plane falls entirely into the limiting tray 443.

[0060] In addition, a support pad 444 is provided at the bottom of the second shock absorbing portion 442 to achieve position limiting protection for the second shock absorbing portion 442 .

[0061] Preferably, the first support plate 21, the second support plate 22 and the third support plate 23 are welded together. The processing method is simple and effectively enhances the structural strength. At the same time, the bottoms of the first support plate 21, the second support plate 22 and the third support plate 23 are respectively welded and fixed to the longitudinal beam 3 to enhance the overall structural stability.

[0062] A fastener is provided between the rear suspension support 4 and the frame girder to fix the rear suspension support 4 to the frame girder. The fastener can be a bolt 6 or other commonly used fastener in the prior art.

[0063] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0064] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0065] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
