Description

Compact mixing box and mixing system Technical Field The utility model relates to the technical field of automobiles, in particular to a compact mixing box and a mixing system. Background The market demand for pick-up cars presents a strong growing situation, particularly in rural and suburban markets. As a multifunctional car model, the pick-up card gradually gains the favor of a plurality of consumers due to the high bearing capacity and good off-road performance. Along with the rapid development of electric vehicles in China, the pick-up card also starts to carry a hybrid system, so that the purposes of strong power and saving electricity are fulfilled. Pi Kaduo employ a non-load bearing body structure featuring two independent systems for the frame and body. The frame is used as a matrix for the whole vehicle assembly and carries a power system and a running system, and the vehicle body mainly provides collision protection and buffering energy absorption effects. Due to this independent arrangement between the frame and the body, and the need for the frame to withstand forces from various directions, the cabin space is relatively limited, thereby limiting the size of the cabin window. In addition, the two-in-one mixing box is used as a core component of a mixing system, the axial size of a motor of the existing motor is large, and the inner rotor of the oil pump and the outer rotor of the oil pump are independently arranged with the motor, so that extra connecting pieces and installation space are needed, the manufacturing cost is increased, the size of the mixing box is relatively large, the size and complexity of the motor are increased, the size of the mixing box is large, the suitability of the whole motor is poor, namely the mixing box is difficult to perfectly fuse with other parts of a motor body, and the performance and the comfort of the whole motor are affected. Therefore, there is a need for a compact mixing tank that is compact in size, reduces the space required in the mixing system, and improves overall vehicle suitability. Disclosure of utility model In view of the above, the present utility model provides a compact mixing tank, which has a compact overall mixing tank, reduces the space required in the mixing system, and improves the overall vehicle adaptability, and a second object of the present utility model is to provide a mixing system including the compact mixing tank. The utility model provides a compact mixing box which adopts the following technical scheme: The utility model provides a compact mix moves case, includes motor and oil pump, the motor includes the shell, the oil pump is integrated in the shell and drives through the motor rotor. Optionally, the shell has installation cavity and oil duct, the oil pump is integrated in the installation cavity, motor rotor penetrates the installation cavity and drives the oil pump, makes the oil pump pass through the oil duct and pumps the engine oil of oil pan to the motor in. Optionally, the mounting cavity is formed with a pump cavity, the oil pump includes an inner oil pump rotor and an outer oil pump rotor, and the inner oil pump rotor and the outer oil pump rotor are located in the pump cavity.
