One end of the oil box shell 4 is connected to the quick-release box cover 1 to form an integrated structure. The oil pressure plate 3 is arranged on a side of the oil box shell 4 away from the quick-release box cover 1. The outer edge of the oil pressure plate 3 matches the inner diameter of the oil box shell 4 so that the oil pressure plate 3 can slide in the inner hole of the oil box shell 4. One end surface of the oil pressure plate 3 facing the inner cavity of the oil box shell 4 is connected to one end surface of the oil bag 6 to form an integrated structure and encapsulates the oil bag 6 in the inner cavity of the oil box shell 4. The mounting hole 32 of the oil pressure plate 3 is aligned with the oil filling hole 61 of the oil bag 6 and fits tightly. A plugging cover 5 is also provided at the mounting hole 32 of the oil pressure plate 3, and a rotating buckle 11 is also provided on the outer side of the quick-release box cover 1.

[0034] In this embodiment, Figure 3 and Figure 4As shown, the quick-release box cover 1 has a positioning boss Ⅰ13 on one end face connected to the oil box shell 4, and a plurality of push-pull buckles 12 are arranged at intervals along the circumferential direction on the end face of the positioning boss Ⅰ13.

The rotating buckles 11 are provided in plurality and are evenly distributed on the outer circumferential surface of the positioning boss Ⅰ13. The quick-release box cover 1 is connected to the oil pump housing through the rotating buckles 11.

[0035] In this embodiment, the oil sac 6 and the quick-release box cover 1 are bonded together into an integral structure by an adhesive, one end face of the oil sac 6 is bonded to the end face of the quick-release box cover 1 located on the inner side of the positioning boss Ⅰ13, and the other end face of the oil sac 6 is bonded to the end face of the oil pressure plate 3 facing the inner cavity of the oil box shell 4 by an adhesive to form an integral structure, for example, by using PE special glue, such as Figure 6 As shown, the quick-release box cover 1 is aligned with the bottom mounting surface 63 of the oil bag 6 and then glued, and the top mounting surface 62 of the oil bag 6 is aligned with the plane side of the oil pressure plate 3 and then glued; it should be noted that: the above-mentioned bonding connection method is not the only one, and the present scheme can also adopt other mechanical connection methods, for example: bosses are provided on the two side planes of the oil bag 6, and threads are provided on the bosses, and the quick-release box cover 1 and the oil pressure plate 3 are respectively connected to the bosses on both sides of the oil bag 6 by threads, so that the oil bag 6, the quick-release box cover 1 and the oil pressure plate 3 form an integrated structure.

[0036] In this embodiment, Figure 5 and Figure 7 As shown, a positioning boss Ⅱ 31 is provided on the side of the oil pressure plate 3 away from the quick-release box cover 1, and the mounting hole 32 is located at the center of the positioning boss Ⅱ 31. A guide fillet 33 is also provided on the end face of the oil pressure plate 3 on the outside of the positioning boss Ⅱ 31.

The outer diameter of the plugging cover 5 matches the aperture of the mounting hole 32. Under the action of external force, the plugging cover 5 can be pressed into the inner cavity of the oil bag 6 through the mounting hole 32 and the oil filling hole 61. The mounting hole 32 on the oil pressure plate 3 is used to cooperate with the oil guide pipe on the oil pump. After the oil pressure plate 3 and the top mounting surface 62 of the oil bag 6 are aligned and glued, the mounting hole 32 will be aligned with the oil filling hole 61 of the oil bag 6 and fit tightly. After the grease is injected into the oil bag 6 through the oil filling hole 61, the mounting fillet 51 of the plugging cover 5 is aligned with the mounting hole 32 and pressed in to seal the grease.

[0037] The above embodiment describes a structure in which the plugging cover 5 can be pressed into the oil bag 6. It should be noted that the above embodiment is only one way to seal the grease, but the structure of the plugging cover is not unique and other shapes can also be used, which will not be listed one by one in this solution.

[0038] In this embodiment, a sealing sticker 2 is further provided on the outer side of the mounting hole 32 and the plugging cover 5. During installation, the sealing sticker 2 is removed, the mounting hole 32 is aligned with the oil guide pipe and inserted, the oil guide pipe is inserted into the mounting hole 32 and matched, the plugging cover 5 is pressed into the oil bag, and the oil box is further pushed inward to a certain distance and then rotated clockwise.
