Description
Technical Field
The invention relates to the technical field of vehicles. In particular, the present invention relates to a motor apparatus for a vehicle and a vehicle including the motor apparatus.
Background
With the aggravation of environmental pollution and the consumption of fossil energy, new energy automobiles have received more and more attention. Currently, new energy vehicles mainly rely on electric motors to generate driving force. The current provided by the vehicle's battery or the like needs to be distributed through the high voltage tank before entering the electric machine. The high-pressure tank in the prior art is usually designed in a suspension type, the end part of the high-pressure tank is installed on an end cover of a motor shell through a fastener such as a bolt, and the whole direction of the high-pressure tank is parallel to the axial direction of the motor. In such a mounting manner, the high-pressure tank is likely to vibrate, which is disadvantageous to the stability of the entire system.
CN 102891577B discloses a switched reluctance motor, in which a terminal box is mounted on a rear end cover of the motor, and a high-voltage socket extends on an axial end face thereof to the outside of the motor in parallel with a motor axis. Such a junction box is unstable in installation, is liable to vibration and drop, and needs to occupy a larger layout space, which is disadvantageous for the compact design of a vehicle space.
Disclosure of Invention
Therefore, an object of the present invention is to provide a motor device and a vehicle having a stable structure and a compact layout.
The above-mentioned object is achieved by an electric machine arrangement according to the invention. The motor device includes a motor housing for enclosing the motor and a high-pressure tank for housing a power connector of the motor, the high-pressure tank being provided outside the motor housing and between the motor housing and a floor of the electric vehicle. According to the design scheme of the invention, the high-pressure box is integrally formed with the motor shell and is arranged on the outer side of the circumferential side wall of the motor shell, and is formed into a hollow shell which is higher than the circumferential side wall in the radial direction; the power joint is arranged on a first end face of the high-pressure box, which is connected with the circumferential side wall of the motor shell, the normal direction of the first end face extends perpendicular to the central axis of the motor shell, and the extension line of the power joint in the direction deviating from the first end face does not intersect with the bottom plate. Preferably, the power supply connection is a high-voltage three-phase connection. Because the installation direction of the power connector on the first end face of the high-pressure box is perpendicular to the axis direction of the motor shell, and the extension line of the power connector departing from the direction of the first end face is not intersected with the bottom plate, the interference between the power connector and the bottom plate of the vehicle is avoided, the layout of the vehicle is more compact, and meanwhile, the structure of the motor device under the layout is more stable and the sealing area required by the motor shell is reduced by integrating the high-pressure box and the motor shell.
According to a preferred embodiment of the invention, the power connection extends parallel to the base plate and perpendicular to the first end face. Under this kind of overall arrangement, the one end that the first terminal surface of high-pressure box is close to motor casing inclines to high-pressure box inside for the other end, makes and forms an acute angle between the first terminal surface outside and the circumference lateral wall of motor casing to make the power connection that stretches out perpendicularly from first terminal surface parallel with the bottom plate, make things convenient for power connection's installation when avoiding interfering.
According to a further preferred embodiment of the invention, a second end face of the high-pressure tank, which is opposite the first end face, is tangential to a circumferential side wall of the motor housing. This arrangement maximizes the internal space of the high-pressure tank without enlarging the overall radial dimension of the motor apparatus.
According to another preferred embodiment of the present invention, a third end surface of the high-pressure tank, which extends perpendicularly to the central axis of the motor housing, is flush with the motor end surface of the motor housing and forms a high-pressure tank mounting opening for mounting internal components of the high-pressure tank. Preferably, the motor device has a motor end cover which can simultaneously cover the motor end face and the high-pressure tank mounting opening. The arrangement facilitates the installation of the internal parts of the high-pressure box, and simultaneously enables the motor shell and the end cover of the high-pressure box to be integrated, thereby simplifying the integral structure of the device.
According to another preferred embodiment of the present invention, the motor housing is formed integrally with a housing of a transmission of a vehicle. The motor shell and the gearbox shell share part of the shell, so that the shell design for the novel integrated electric drive axle is facilitated.
According to another preferred embodiment of the invention, a motor power input for powering the motor is accommodated in the hollow housing of the high-pressure tank. The external power line is accessed from the power connector and then directly enters the motor shell from the high-voltage box so as to supply power to the motor, and the wiring length is reduced to the maximum extent.
The above problem is also solved by a vehicle according to the invention, comprising an electric machine arrangement with the above features.

The invention is further described below with reference to the accompanying drawings. Identical reference numbers in the figures denote functionally identical elements. Wherein:
fig. 1 is a perspective view of a motor housing integrated with a high-pressure tank according to an embodiment of the invention;

Detailed Description
Fig. 1 and 2 are perspective views of a motor housing integrated with a high-pressure tank according to an embodiment of the present invention. As shown in fig. 1, the motor housing 1 has a cylindrical shape adapted to the motor, and the high-pressure tank 2 is fixed to, preferably integrally formed with, a circumferential side wall of the motor housing 1 and formed as a hollow housing that is radially higher than a side surface of the motor housing 1, and is internally provided with, for example, a high-pressure three-phase line transfer block (not shown). Two opposite end faces of the high-pressure tank 2, the normal direction of the first end face 3 and the second end face 4, extend perpendicularly to the axis of the motor, while the third end face 5 of the high-pressure tank 2 is flush with the end face of the motor housing 1, and a high-pressure tank mounting opening 6 is formed in the third end face 5 so as to mount internal components (e.g., a high-pressure three-phase line transfer block) of the high-pressure tank 2. The high-pressure tank mounting opening 6 may be covered by a motor housing end cap (not shown). As shown in fig. 2, a power supply connector 7 is mounted on the first end surface 3 of the high-voltage tank 2 extending parallel to the central axis of the motor housing, and the power supply connector 7 extends in a direction perpendicular to the first end surface 3 and perpendicular to the motor axial direction. The power supply connector is, for example, a high-voltage three-phase power supply connector.
Fig. 3 is a side view of a motor housing in an axial direction according to an embodiment of the present invention. As shown in fig. 3, one end of the first end surface 3 close to the motor housing 1 is inclined to the inside of the high pressure tank 2 with respect to the other end such that an acute angle is formed between the outside of the first end surface 3 and the circumferential side wall of the motor housing 1. In this configuration, the power connector 7 mounted on the first end surface 3 is inclined toward the direction close to the motor housing 1 so that an extension line of the power connector 7 in a direction away from the first end surface 3 does not intersect with the floor panel 8 of the vehicle. Preferably, the first end face 3 is inclined at an angle such that the high-voltage power supply connector 7 is parallel to the base plate 8, so that a smaller installation space is required between the motor device and the base plate 8 while avoiding interference between the power supply connector 7 protruding from the first end face 3 and the base plate 8.
The second end face 4 of the high-pressure tank 2 is opposed to the first end face 3. Preferably, one end of the second end face 4 close to the motor housing 1 may be inclined to the outside of the high-pressure tank 2 with respect to the other end such that the second end face 4 is tangential to the circumferential side wall of the motor housing 1. Thus, the internal space of the high-pressure tank 2 can be maximized without enlarging the overall radial dimension of the motor device.
The motor apparatus according to the embodiment of the present invention may be applied to a motor product integrated with a transmission case of an electric vehicle. In this case, the other end face of the motor housing 1 opposite to the third end face 5 is a part shared with the transmission, and is suitable for the design of the housing of the novel integrated electric drive axle.
