Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0028] It should also be noted that the orientation terms such as left, right, up and down in the embodiments of the present invention are only relative concepts or refer to the normal use state of the product, and should not be regarded as re...

Abstract

The invention belongs to the technical field of electric vehicles, and particularly relates to a controller and an electric vehicle provided with the controller. The controller comprises a heat radiator used for radiating heat, a bottom shell and an integrated circuit structure, wherein the bottom shell is arranged opposite to the heat radiator and forms an accommodating space together with the heat radiator in an enclosing manner, the integrated circuit structure is accommodated in the accommodating space, and the integrated circuit structure comprises a circuit board and a power tube which is electrically connected to the circuit board. The controller further comprises a pressing and laminating structure which is used for pressing and laminating the power tube to the heat radiator. The pressing and laminating structure comprises an elastic soft rubber member which is made of soft rubber and presses and laminates the power tube to the heat radiator through an elastic restoring force, wherein one end of the elastic soft rubber member is abutted against the power tube, and the other end of the elastic soft rubber is abutted against the bottom shell. Damages imposed on the power tube are avoided through setting the pressing and laminating structure because the elastic soft rubber member does not generate rigid extrusion for the power tube.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a controller and an electric vehicle with the controller. Background technique [0002] The controller of existing electric vehicle all is that power tube (MOS tube) is closely fixed on the radiator with screw when assembling, and then is installed on the electric vehicle car body along with radiator. Among them, the screw is used to fix the power tube tightly to the radiator, and the screw needs to be rotated. When tightening the screw, if the operation method is improper, that is, the torque is too large or the screw is deflected, it will damage the power unit. mechanical damage to the outer shell of the power device and affect the internal wafer of the power device, that is, when the power tube is tightly fixed to the radiator, it is easy to cause damage to the power tube. [0003] In addition, the screw must pass through the power tube, and there is a c...
