Embodiment Construction

[0016] Further describe the technical scheme of the present invention below in conjunction with accompanying drawing: as figure 1 As shown, the sealing structure of the controller includes an end cover 1, a box body 2, a screw 3 and a sealing strip 4. The end cover 1 is connected to the box body 2 through the screw 3, and the end cover 1 is connected to the box body 2 One side of the screw 3 is tightly connected, and a gap is provided on the other side of the screw 3, and the gap includes a transverse gap and a longitudinal gap. The sealing strip 4 is a planar sealing strip, which is arranged in the gap, and the thickness of the sealing strip 4 is greater than the width of the gap, which ensures that the sealing strip 4 can be squeezed when the screw 3 is tightened to achieve a sealing effect; The strip 4 is provided with adhesive on the side close to the box body 2, and the sealing strip 4 can be adhered to the box body 2 during installation, and the installation is simple; a...

Abstract

The invention discloses a sealing structure for controller. The sealing structure for the controller comprises an end cover (1), a box body shell (2), a bolt (3) and a sealing strip (4). The end cover (1) is connected with the box body shell (2) by the bolt (3); the end cover (1) is in sealing connection with the box body shell (2) at one side of the bolt (3); the other end of the bolt (3) is provided with a clearance; the sealing strip (4) is arranged in the clearance; the thickness of the sealing strip (4) is greater than the width of the clearance; a rotation angle is formed on the sealing strip (4); a gap is formed at the rotation angle; and one side of the sealing strip (4) close to the box body shell (2) is provided with back glue. The invention provides the sealing structure for the controller and the sealing structure has low production cost, good sealing performance and strong electromagnetic interference shielding capacity due to the special design of the sealing strip structure.

Description

technical field [0001] The invention relates to a controller sealing structure. Background technique [0002] Since the use environment and maintenance environment of electric vehicles are related to water, the electrical circuit in the vehicle has high requirements for waterproofing of the shell, and generally adding a gasket can meet the requirements. However, electric vehicles need a power battery pack to supply power, and the voltage and current regulation of the motor is controlled by the frequency conversion of the controller. The switching frequency of the power module in the controller is as high as 10k Hz, and the electromagnetic interference is very serious; at the same time, the electromagnetic interference from the outside to the controller is also Very serious. Most traditional controllers can only meet high waterproof performance, and the shielding ability for electromagnetic interference is far from meeting the working requirements of the sealing structure of...
