Description

Motor protective shell for electric automobile motor

Technical Field

The utility model relates to an electric automobile motor technical field, in particular to motor protecting crust for electric automobile motor.

Background

Types of electric vehicles: a pure electric vehicle (BEV), a Hybrid Electric Vehicle (HEV), and a fuel cell vehicle (FCEV). The technical planning of new energy vehicles is implemented in the fifteen' period in China, and the 863 project invests 20 million yuan of research and development cost, so that the research and development pattern of the electric vehicles taking three technical routes of pure electric power, oil-electricity hybrid power and fuel cells as three longitudinal directions and taking three common technologies of a multi-energy power assembly control system, a driving motor and a control system thereof, a power storage battery and a management system thereof as three transverse directions is formed. More than 200 whole vehicles and part enterprises, universities and scientific research institutions in total and more than 3000 scientific and technological personnel directly participate in the research and development of the special electric vehicle. At present, the research and development of electric automobiles in China are obviously advanced. Thousands of patents have been developed and a number of electric vehicle models have been developed. The plug-in and oil-electricity hybrid electric vehicles of enterprises such as Biedi, Chery, Changan and the like have the marketing condition, three key technologies initially have the capacity of supporting and developing the electric vehicles, the key point for developing the electric vehicles lies in whether the enterprises in China can master the core technology, in China, low-speed electric vehicles are not prohibited by the regulations of main departments such as the State development committee, the Ministry of industry and the Ministry of industry, but lead-acid batteries (low industry threshold, low starting point, high environmental pollution and easy standard exceeding of blood and lead) are not new energy lithium batteries and have limited endurance capacity (usually 50-80 km for one-time charging) so as not to meet the requirements of technical indexes such as 'quality distribution' in the technical conditions of pure electric passenger vehicles of the State Ministry of industry, and do not belong to the technical indexes such as 'energy conservation and new energy vehicles' development planning (2012-2020 years) of the national pure electric vehicle industry encouraging the transformation of the major orientation . The key core technologies of the electric automobile are three: the power battery is the first, the motor is the second, and the control system is the third, wherein the motor is the central power component, so need carry out good protection to the motor.

The motor of the existing electric automobile is directly fixed in the automobile engine room through the fixing seat of the motor, and the loosening phenomenon often occurs along with the long-term use of the automobile in the mode, so that the motor is damaged due to overlarge vibration.

SUMMERY OF THE UTILITY MODEL

Not enough to the above-mentioned among the prior art, the utility model provides a motor protecting crust for electric automobile motor, its is rational in infrastructure, and further fixed motor reduces the impaired condition of motor and takes place.

In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a motor protecting crust for electric automobile motor, includes protecting crust and lower protecting crust, go up protecting crust and lower protecting crust and be semi-circular structure, one side of going up the protecting crust is articulated mutually with one side of protecting crust down, the protecting crust is hollow structure down, go up the protecting crust opposite side and peg graft in the opposite side of protecting crust down, it is the through-hole one of three rows to be equipped with the row number on the lateral wall of one side that goes up protecting crust and lower protecting crust peg graft mutually, be equipped with on the protecting crust lateral wall down with through-hole one matched with through-hole two, the cooperation is equipped with fixing bolt between through-hole one and the through-hole two, the protecting crust bottom is equipped with the electro-magnet down, the electro-magnet links to each other with.

as an improvement: and a fixing hole for the motor fixing seat to pass through is formed in the bottom of the lower protective shell.

As an improvement: and a third through hole for the motor controller to pass through is formed above the upper protective shell.

as an improvement: the electromagnet is positioned in the center of the lower protective shell.

Compared with the prior art, the utility model the advantage lies in: install protecting crust and lower protecting crust additional at the motor outside to install the electro-magnet additional in protecting crust bottom down, can reduce the atress of bolt at the in-process of traveling, thereby effectively prevent that the motor is not hard up, in addition, go up the many grades of adjustable of distance between protecting crust and the lower protecting crust, the suitability is stronger.

Detailed Description

The following describes the present invention with reference to the accompanying drawings.

As shown in fig. 1, 2, 3 and 4, the motor protective shell for the electric automobile motor comprises an upper protective shell 1 and a lower protective shell 2, wherein the upper protective shell 1 and the lower protective shell 2 are both of a semicircular structure, one side of the upper protective shell 1 is hinged with one side of the lower protective shell 2, the lower protective shell 2 is of a hollow structure, the other side of the upper protective shell 1 is inserted into the other side of the lower protective shell 2, three rows of first through holes 3 are formed in the side wall of the side, inserted into the upper protective shell 1 and the lower protective shell 2, of the side wall, second through holes 4 matched with the first through holes 3 are formed in the side wall of the lower protective shell 2, fixing bolts 5 are arranged between the first through holes 3 and the second through holes 4 in a matching mode, an electromagnet 7 is arranged at the bottom of the lower protective shell 2, and the electromagnet 7 is connected with an automobile storage battery.
