Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of single motor controller vibration testing of new energy vehicles, in particular to a single motor controller vibration testing device especially suitable for new energy vehicle controllers. BACKGROUND

[0002] In response to the new energy strategy, new energy vehicles represented by pure electric vehicles and hybrid vehicles are developing rapidly, and controllers, as essential components of new energy vehicles, are also constantly maturing. Currently, controllers for new energy vehicles can be divided into single motor controllers and double motor controllers. Single motor controllers are simpler in structure, smaller in size, and have a smaller vibration input level than double motor controllers, and are mainly used in pure electric vehicles. One of the indicators that tests the reliability of single motor controllers is the vibration test result. During vibration testing, the posture of the single motor controller and its assembly in the vehicle must be consistent. In order to meet the simulation of the posture of the single motor controller on the vehicle and the vibration standard level, a vibration testing device is needed. The controller is fixed on the vibration table through a connecting structure, so that the controller, the connecting structure, the vibration table, and the vibration source generating device form a complete vibration testing device.

[0003] The traditional vibration testing device provided on the market today usually has a relatively complex connection and support structure, and the overall layout of its components is not compact enough, resulting in a high overall consumption of the testing device, a complex fixed connection method, and a long test preparation time, which increases the cost of single motor controller vibration testing. In addition, the existing testing device can usually only simulate a single motor controller in a vertical or horizontal posture.

[0004] Therefore, it is a technical problem to be solved in the field to provide a new energy vehicle single motor controller vibration testing device that is simple and compact in overall structure, convenient to fix and connect, and can simultaneously simulate a single motor controller in a vertical or horizontal posture while ensuring the overall structural strength.

As a preferred embodiment, at least one third reinforcing rib is arranged on the upper surface of the top end of the top shell 22. According to the modal analysis principle in structural dynamics, the first-order mode of the upper surface of the top shell 22 is close to the operating frequency of the motor, which causes the top shell 22 to be easily damaged due to resonance. Therefore, in order to increase the frequency of the first-order mode, at least one third reinforcing rib is designed on the upper surface of the top end of the top shell 22 to avoid the risk of resonance of the top shell 22. As a preferred embodiment, the bottom opening of the top shell 22 and the rim (or flange) of the top opening of the bottom shell 21 are correspondingly attached and locked by a plurality of bolts or buckle structures, so that the top shell 22 is fastened to the bottom shell 21 and closes the top opening of the bottom shell 21. As a more preferred embodiment, a sealing ring or glue filling can be arranged on the abutting contact surface between the top shell 22 and the bottom shell 21 to prevent air leakage due to poor sealing of the abutting contact surface between the top shell 22 and the bottom shell 21.

[0063] In the embodiment, the vertical single motor controller 2 further comprises:

[0064] The waterway cover plate 25 is fixed to the back surface (i.e. the bottom outer side) of the bottom shell 21 away from the top shell 22 by a plurality of bolts or buckle structures or welding. In an embodiment, an annular waterway is provided on the back surface of the bottom shell 21 away from the top shell 22 for cooling the power devices of the single motor controller installed in the internal accommodating space enclosed by the bottom shell 21 and the top shell 22; as a preferred embodiment, the waterway on the bottom shell 21 is sealed by sealing glue between the annular waterway provided on the back surface of the bottom shell 21 away from the top shell 22 and the waterway cover plate 25 to improve the sealing property thereof.

[0065] Please refer to Figures 1-3 , 5, in the embodiment, the vertical controller and wire harness fixing assembly 4 comprises:

In the embodiment, the bottom shell 21 of the vertical single motor controller 2 is fastened to the first vertical plate 41 through the light holes (i.e. through holes) provided at the four supporting corners thereof through bolts, so that the vibration test device for single motor controller is still compact in overall structure, light in weight, small in occupied installation space after the vertical single motor controller 2 is installed, the assembly difficulty of the vibration test device is reduced, the manufacturing cost of the vibration test device is reduced, the vibration test preparation time is reduced, and the development trend of the miniaturization of the single motor controller is better met.

[0067] In this embodiment, the vertical high-voltage wire harness fixing member 42 and the vertical low-voltage wire harness fixing member 44 are both L-shaped bent sheet metal parts, and the vertical high-voltage wire harness fixing member 42 and the vertical low-voltage wire harness fixing member 44 are fixed to the top of the first vertical plate 41 at one end of the bending part perpendicular to the vibration table 1 by two or more bolts or snap structures or welding (parallel and fitted on the side of the first vertical plate 41 facing away from or facing the vertical single-motor controller 2, and in this embodiment, installed on the side of the first vertical plate 41 facing away from the vertical single-motor controller 2); the vertical controller and wire harness fixing assembly 4 also includes: a vertical high-voltage wire harness pressing block 43, which is detachably mounted on the other end of the vertical high-voltage wire harness fixing member 42 parallel to the vibration table 1 by two or more screws passing through the corresponding screw holes 8 or snap structures, and the other end of the vertical high-voltage wire harness fixing member 42 parallel to the vibration table 1 and the vertical high-voltage wire harness pressing block 43 are respectively provided with at least one pair of corresponding vertical high-voltage wire harness 231 snaps.

The other end bending part is provided with a vertical low-voltage wire harness card slot 441 for clamping the low-voltage wire harness 241 perpendicular to the vibration table 1 and a cable tie fixing slot 442 for fixing the low-voltage wire harness 241 perpendicular to the vibration table 1. Since the wire diameter of the low-voltage wire harness 241 is relatively small and relatively soft, it needs to be firmly fixed by a flexible cable tie. Therefore, it adopts a cable tie and a cable tie fixing slot 442 for binding. While firmly binding the flexible low-voltage wire harness 241, it can reduce the material consumption of parts and processing time, thereby improving production efficiency and reducing production costs. As a preferred embodiment, the slot of the cable tie fixing groove 442 is provided with a connecting beam for tying and fixing the low-voltage wiring harness 241. The end of the low-voltage wiring harness 241 of the low-voltage plug-in 24 and the bent part close to one end of the bottom shell 21 are passed through the cable tie and fastened to the cable tie fixing groove 442 and the connecting beam of the slot, which are pressed against the vertical low-voltage wiring harness slot 441 of the vertical low-voltage wiring harness fixing part 44 to prevent the low-voltage wiring harness 241 from swinging during the vibration test and causing wear of the wiring harness and the device.
