Embodiment Construction

[0022] The following is further described in detail through specific implementation methods:

[0023] The reference signs in the drawings of the specification include: shell body 1, threaded hole 2, U-shaped cavity 3, sealing elastic bag 4, ammonia water 401, baffle plate 5, card slot 6, card bar 7, spring 8, steel wire 9 , Limiting block 10, push post 11, fixed pin 12, contact rod 13, elastic post 14.

[0024] The embodiment is basically as figure 1 As shown, the range extender housing includes a housing body 1, and the housing body 1 is provided with eight threaded holes 2 and eight U-shaped cavities 3, and each U-shaped cavity 3 partially surrounds a threaded hole 2. Each U-shaped cavity 3 is provided with a sealed elastic bag 4 and a baffle 5 , and the sealed elastic bag 4 is located between the baffle 5 and the bottom of the U-shaped cavity 3 . The sealed elastic capsule 4 is filled with liquid, and the boiling point of the liquid is between 30° C. and 55° C. In this em...

Abstract

The invention relates to the technical field of electric vehicles, and discloses a range extender shell. The range extender shell comprises a shell body, a plurality of threaded holes are formed in the shell body, a plurality of U-shaped cavities are formed in the shell body, baffles and sealing elastic bags are arranged in the U-shaped cavities, clamping grooves are formed in the side walls of the U-shaped cavities, springs are fixedly connected between the clamping strips and the baffles, the clamping strips extend into the clamping grooves, and limiting blocks used for limiting rotation ofthe clamping strips are fixedly connected to the two ends of the baffles. The baffles are fixedly connected with push columns, and the tops of the push columns are provided with wedge-shaped faces. Through grooves communicating with the threaded holes and the U-shaped cavities are formed in the side walls of the threaded holes, fixing pins are slidably connected into the through grooves, the end,facing the U-shaped cavities, of each fixing pin is provided with a wedge-shaped face, and the wedge-shaped faces of the fixing pins are opposite to the wedge-shaped faces of the push columns. According to the range extender shell, the sealing elastic bag can be expanded through heat, so that the baffle is pushed to move, the fixing pin locks the bolt in the threaded hole, the bolt is prevented from loosening, and therefore a range extender is prevented from being too large in vibration amplitude.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, and specifically discloses a range extender housing. Background technique [0002] Electric vehicles are powered by on-board power supplies, and use motors to drive wheels, which can achieve the purpose of energy saving and emission reduction. In order to improve the cruising range of the electric vehicle, a range extender can be installed in the electric vehicle. The range extender can convert chemical energy into kinetic energy, and then convert kinetic energy into electrical energy, and the electrical energy is mainly used to drive the motor to work, and to charge the vehicle power supply, so as to maintain the battery life of the electric vehicle. At present, threaded holes are provided on the casing of the range extender, and the range extender is fixedly installed in the electric vehicle by using the cooperation between the bolt and the threaded hole. When the range extender is ...
