The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The core of the invention is to provide an engine front end cover which can reduce the weight of an engine body while realizing the installation of a fan and an air conditioner compressor. Another core of the present invention is to provide an engine front end cover assembly including the above engine front end cover, which can make the overall weight of the engine light; still another core of the present invention is to provide an engine including the engine front end cover assembly described above, which is lightweight in its entirety.

Referring to fig. 1-3, fig. 1 is a schematic structural diagram of a front end cover of an engine according to an embodiment of the present invention; FIG. 2 is a schematic illustration of a front engine cover assembly according to an embodiment of the present invention; fig. 3 is a partial schematic view of fig. 2.

As shown in fig. 1, the present invention provides an engine front end cover, including a front end cover body 1, the front end cover body 1 is provided with a fan mounting part 2 and a supporting platform 3, wherein, the fan mounting part 2 is used for mounting a wind-protecting ring bracket 51 of a fan 5; the support platform 3 is intended to abut against the end of an adjusting screw 61 of the air-conditioning compressor 6.

It can be understood that the front end cover body 1 belongs to the main structure of the engine front end cover, and the structure is the same as that of the conventional engine front end cover in the prior art, and the description is omitted here. For example, the front head cover body 1 is provided with a crankshaft front oil seal mounting hole 11 for mounting the crankshaft front oil seal 7.

The invention is characterized in that the front end cover body 1 is provided with a fan mounting part 2 and a supporting platform 3, that is, the invention utilizes the fan mounting part 2 of the front end cover body 1 to provide a fixed supporting point for a wind protection ring bracket 51 of a fan 5 so as to mount the fan 5 on the front end cover body 1 through the wind protection ring bracket 51; and the supporting platform 3 is used for providing a supporting point for the adjusting screw 61 of the air-conditioning compressor 6, so that when the adjusting screw 61 is rotated, the adjusting nut 62 in threaded connection with the adjusting screw 61 drives the air-conditioning compressor 6 to move relative to the engine body.

Therefore, the fan mounting part 2 belongs to the mounting structure of the wind protection ring bracket 51 of the fan 5, the supporting platform 3 belongs to the supporting structure of the adjusting screw 61 of the air-conditioning compressor 6, and the fan mounting part 2 and the supporting platform 3 are integrated on the front end cover body 1, so that the front end cover of the engine becomes a functional integrated structural part with the characteristics of the mounting structure of the wind protection ring bracket 51 and the supporting structure of the adjusting screw 61. That is, during installation, the air protecting ring support 51 is indirectly installed on the engine body through the engine front end cover, and the end part of the adjusting screw 61 of the air conditioner compressor 6 is indirectly supported on the engine body through the engine front end cover, so that the installation structure of the air protecting ring support 51 and the supporting structure of the adjusting screw 61 are avoided being directly arranged on the engine body. Because the engine front end housing is cast aluminium material, consequently, with fan installation department 2 and supporting platform 3 integration on the engine front end housing, compare in with fan installation department 2 and supporting platform 3 direct setting up on the engine organism of cast iron material, can alleviate the whole weight of engine for the whole quality of engine reduces, and reduces the overall structure size of engine.

In the present embodiment, the specific structure of the fan mounting portion 2 is not limited as long as the cowl brace 51 to which the fan 5 can be fixedly mounted is used.

Preferably, in addition to the above embodiment, the fan mounting portion 2 includes a boss 21 and a bolt hole 22 provided in the boss 21. That is, when the wind-guard ring support 51 is mounted, the boss 21 abuts against the wind-guard ring support 51, the boss 21 provides a supporting force for the wind-guard ring support 51, the mounting hole of the wind-guard ring support 51 is aligned with the bolt hole 22 on the boss 21, and the wind-guard ring support 51 and the boss 21 are connected together by a bolt.
