[0002] The statements herein only provide background art related to the utility model and do not necessarily constitute prior art.

[0003] A hybrid loader refers to a loader that combines a traditional fuel power system and an electric hybrid power system. Initially, hybrid technology was mainly applied to urban transportation vehicles such as buses. With the strengthening of environmental protection policies and the promotion of market demand, hybrid technology has gradually been introduced into the field of loader machinery technology; the rear frame, as one of the key components of a hybrid loader, bears the weight of the rear part of the loader. Therefore, the design of the rear frame is not only related to the overall stability and load-bearing capacity of the loader, but also directly affects the layout and performance of the hybrid system. The inventor found that there are some technical problems in the design of the existing loader rear frame, for example:

[0004] The drive motor needs to be close to the engine position, but the existing rear frames of hybrid loaders generally only have the installation position of the engine, and lack a position that can directly or indirectly place the drive motor, and it is impossible to simultaneously carry hybrid devices (such as engines, engine range extenders, etc.), resulting in low utilization rate of the rear frame; in addition, when the hybrid loader is only driven by the motor, there is a certain range anxiety. Summary of the Utility Model

Detailed implementation manners

[0024] The following will describe the detailed implementation manners of this embodiment with reference to the accompanying drawings.

[0025] Refer to Figure 1 , an embodiment of the present utility model provides a rear frame of a hybrid loader, which includes a hinge frame 1. Both ends of the hinge frame 1 are respectively fixedly connected to a left side plate 2 and a right side plate 3, and the left side plate 2 and the right side plate 3 are arranged oppositely. Further, the upper end of the hinge frame 1 is used for fixedly installing a front support of the driver's seat, and the left side plate 2 and the right side plate are used for fixedly installing a rear support of the cab.

[0026] Refer to Figure 2 , there are two engine range extender supports 4 and two engine supports 5 between the left side plate 2 and the right side plate 3; wherein, the two engine range extender supports 4 and the two engine supports 5 are respectively used for installing an engine range extender and an engine. Therefore, the rear frame of the present utility model can realize the simultaneous installation of hybrid devices (engine range extender, engine), improving the utilization rate of the rear frame.

[0027] Further, the two engine range extender supports 4 and the two engine supports 5 are respectively symmetrically fixed to the inner sides of the left side plate 2 and the right side plate 3, and the symmetrical design can ensure the overall balance of the frame.

[0028] Refer to Figure 2, a cross beam 6 is further provided between the left side plate 2 and the right side plate 3, and the cross beam 6 is approximately H-shaped; and both ends of the cross beam 6 are fixedly connected to the left side plate 2 and the right side plate 3 respectively. The design of this cross beam 6 can enhance the overall rigidity of the rear frame and avoid deformation of the rear frame.

[0029] Referring to Figure 1 and Figure 2 , the two engine range extender supports 4 include a first flat plate 41 and a first connecting plate 42, and the two engine supports 5 include a second flat plate 51 and a second connecting plate 52; the lower ends of the first connecting plate 42 and the second connecting plate 52 are both welded to the cross beam 6.

[0030] Referring to Figure 2 , the engine range extender supports 4 and the engine supports 5 on the left and right side plates are arranged at intervals. Further, the lower end of the first connecting plate 51 is welded to the front end of the cross beam 6, and the lower end of the second connecting plate 52 is welded to the rear end of the cross beam 6. The present utility model takes into account that since the engine is heavy, when the loader lifts the same weight of an object, if the center of gravity is unstable during the reverse process, there may be a problem of tipping over. The installation positions of the engine range extender support 4 and the engine support 5 can ensure the stability of the center of gravity of the entire frame after the engine range extender and the engine support are installed on the rear frame.

[0031] Referring to Figure 3 , a hydraulic oil tank fixing seat 7 is provided on the outer side of the front part of the left side plate 2, and the hydraulic oil tank fixing seat 7 is used to firmly fix the hydraulic oil tank and reduce the influence of the vibration and noise generated during the operation of the hydraulic system on the hydraulic oil tank and the entire hydraulic system. Preferably, an electric control box fixing seat can be provided on the outer side of the front part of the right side plate for installing the electric control box.

[0032] Referring to Figure 2 , Figure 3 , fuel tank fixing seats 8 are symmetrically provided on the outer sides of the rear parts of the left side plate 2 and the right side plate 3, and the fuel tank fixing seats 8 are used to firmly fix the fuel tank, that is, the fuel tank is horizontally placed on the left and right side plates, and through reasonable fixing methods such as threaded connection and bolt fastening, the fuel tank is prevented from fuel leakage due to loosening or damage.

[0033] Referring to Figure 2 , a rear beam 9 and a tail plate 10 are further arranged at intervals at the other ends of the left side plate 2 and the right side plate 3 relative to the connecting hinge frame 1.

[0034] Further, on the outer sides of the left side plate 2 and the right side plate 3 and at the middle positions between the rear beam 9 and the tail plate 10, a first radiator mounting seat 11 and a second radiator mounting seat 12 are respectively fixedly arranged. The first radiator mounting seat 11 and the second radiator mounting seat 12 are used to stably fix the radiator. By arranging them on the outer sides, it can ensure the effective convection of the radiator with the surrounding air and improve the heat dissipation efficiency; auxiliary heat dissipation devices such as air guide plates can also be equipped on the mounting seats to guide the air flow so that the radiator can better dissipate the heat.

[0035] Referring to Figure 2 , the rear beam 9 encloses the tail plate 10 into a car body shape for mounting a counterweight; specifically, it can be used for hanging and mounting a bridge tube with a drive motor.

[0036] Therefore, the rear frame of the present utility model can realize the simultaneous mounting of hybrid devices such as an engine range extender, an engine, and a drive motor, significantly improving the overall utilization rate of the rear frame; and with the addition of the engine range extender, it can alleviate the mileage anxiety of hybrid loaders when relying solely on electric drive.

[0037] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, it is not a limitation to the protection scope of the present utility model. Those skilled in the art should understand that based on the technical solutions of the present utility model, various modifications or deformations that can be made without creative efforts by those skilled in the art are still within the protection scope of the present utility model.
