[0022] In order to make the purpose, technical scheme and advantage of the utility model more clear, the implementation of the utility model will be described in further detail below with reference to the drawings.

[0023] Please refer to Figs. 1-3 The utility model provides a damping mechanism for electric fork truck, including fork truck main body 1, the middle part of fork truck main body 1 is provided with cockpit 2, cockpit 2 inside is provided with battery 3, the inside bottom of cockpit 2 is provided with support frame 4, support frame 4 top fixedly connected with limiting frame 5, support frame 4 middle part is provided with grating net 6, and support frame 4 top four corner places all are provided with first air cushion 7.

[0024] In the embodiment, the first air cushion 7 is fixedly connected with the nylon flannelette belt 8 on the back, the nylon hook belt is fixedly connected with the inner wall of the cockpit 2, the nylon flannelette belt 8 is hooked with the nylon hook belt correspondingly, which facilitates the installation of the first air cushion 7 in the cockpit 2.

[0025] Support frame 4 top both ends are provided with second air cushion 9, and first air cushion 7 and second air cushion 9 are located on the side wall of limiting frame 5, and the limiting frame 5 is arranged, so as to limit the position of first air cushion 7 and second air cushion 9, facilitating the positioning installation of the two.

[0026] The second air cushion 9 is three centimeters higher than the top surface of the limiting frame 5, so that the bottom of the battery 3 is supported by the second air cushion 9 at both ends, facilitating the protection of the battery 3 and playing a buffering role when the vehicle is jolted.

[0027] The bottom of the cabin 2 is provided with an exhaust fan 10, and the two sides of the cabin 2 are provided with air inlets 12. The exhaust fan 10 is provided with positioning pins 11 at four corners, which are threadedly connected with the bottom of the cabin 2, facilitating the fixation of the exhaust fan 10. The bottom of the cabin 2 is provided with air holes corresponding to the exhaust fan 10, facilitating the heat dissipation of the exhaust fan 10.

[0028] The top of the cabin 2 is provided with a hatch 13, and the hatch 13 is fixedly connected with a buffer pad 14.
