Problems solved by technology

[0003] At present, an inverter is usually installed on an electric vehicle to convert the DC power of the battery into an AC power, so as to facilitate the driving of the electric vehicle. The electric vehicle is usually a small body, and its inverter is usually simply installed on the body, while the inverter The inverter is an electronic device, and if it is exposed to the outside for a long time, it is easy to cause damage to the inverter and shorten its service life. Therefore, it is necessary to protect the inverter. At present, the inverter is usually fixed by a mounting frame. And protect the frame, but the protection range is small and the effect is poor

Embodiment 1

[0030] see Figure 1-2 As shown, the present invention provides a protective structure for an inverter device for an electric vehicle through improvement, including a top cover plate 1, a bottom plate 2, an arc connector 3, a right side plate 4, a left side plate 5, a rear seal Plate 6, external fixing ring 7, heat dissipation device 8, fixing structure 9, bidirectional clamping mechanism 10 and synchronous pushing mechanism 11, the top cover plate 1 and the bottom plate 2 are symmetrically arranged up and down, and the two sides are symmetrical to the left and right through the arc connector 3 The set right side plate 4 is connected with the left side plate 5, and forms a rectangular cavity structure through the back cover plate 6 at the rear end, which is used for embedded installation of the inverter and protects the inverter. The top cover plate 1 and the bottom plate 2 The upper and lower sides of the front end are provided with external fixing rings 7 in an arc-shaped st...

Embodiment 2

[0036] The present invention provides a protective structure for an inverter device for an electric vehicle by improving the protection structure. The air outlet of the blower 83 is communicated with the inside of the air collecting box 81 , so that the wind delivered by the blower 83 can enter into the air collecting box 81 after the blower 83 works. The first air transmission pipe 86 is communicated with the upper end of the air collecting box body 81, so that the wind power collected in the air collecting box body 81 can be transported to the bottom plate 2 through the first air transmission pipe 86, and the second air conveying pipe 88 is connected to the collecting box body 81. The rear and middle parts of the air box body 81 are connected, so that the wind power collected in the air collecting box body 81 can be transported to the rear sealing plate 6 through the second air supply pipe 88. Rubber pads 93 are provided in the five pipe sleeves 92, which is convenient for To...

Abstract

The invention discloses a protection structure of an inverter device for an electric vehicle. The protection structure comprises a top cover plate, a bottom plate, an arc-shaped connecting piece, a right side plate, a left side plate, a rear sealing plate, an external fixing ring, a heat dissipation device, a fixing structure, a two-way clamping mechanism and a synchronous pushing mechanism. According to the invention, the heat dissipation device is arranged, a first air conveying pipe and a second air conveying pipe are used for conveying air, and the air is conveyed into a rectangular cavitystructure through a first air outlet and a second air outlet, so that heat dissipation processing can be conducted on the installed inverter from different positions, and the heat dissipation efficiency is improved; and by arranging the synchronous pushing mechanism, the left clamping plate and the right clamping plate can be driven by a telescopic left pushing rod and a telescopic right pushingrod to move synchronously, and the inverter can be conveniently and rapidly clamped and fixed.

Description

technical field [0001] The invention relates to the related field of electric vehicle accessories, in particular to a protective structure for an inverter device for an electric vehicle. Background technique [0002] Electric vehicles, that is, electric drive vehicles, have another name called electric drive vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, electric vehicles use batteries as energy sources. Through controllers, motors and other components, electric energy is converted into mechanical energy to move, so as to control the magnitude of the current and change the speed of the vehicle. With the development of society, electric vehicles have been popularized in daily life. . [0003] At present, an inverter is usually installed on an electric vehicle to convert the direct current of the battery into an alternating current, so as to facilitate the driving of the electric vehicle. The electric vehicle i...
