[0020] The technical scheme in the utility model embodiment will be clearly and completely described below with reference to the drawings in the utility model embodiment.

[0021] Please refer to Figures 1-5 The utility model provides a technical scheme: a freight electric vehicle with quick compartment replacement, comprising frame 1 and compartment 4, the rear of frame 1 is rotatably connected with support 2, lifting mechanism 3 for lifting compartment 4 is installed on support 2, a plurality of gas struts 7 are installed between support 2 and frame 1;

[0022] Push-pull type compression 8 for fixing the position of support 2 is symmetrically installed on support 2.

[0023] As shown in Figure 3 And Figure 4 Lifting mechanism 3 adopts scissor structure, comprising two scissor arms 31; two scissor arms 31 are bolted into scissors arm structure, and placement platform 33 for placing compartment 4 is installed on the upper side of two scissor arms 31; through the above setting, the mutual cooperation of two scissor arms 31 can drive placement platform 33 to move up and down, and then drive compartment 4 to move up and down, and complete the replacement work of compartment 4.

[0024] As shown in Figure 3 And Figure 4As shown: one end of two scissor arms 31 is hinged with the placing platform 33 and the support 2 respectively, the other end is respectively provided with a roller 34 and is slidingly connected with the placing platform 33 and the support 2, and a hydraulic oil cylinder 32 is installed between the support 2 and the scissor arm 31; through the above setting, the extension and retraction of the hydraulic oil cylinder 32 makes the two scissor arms 31 move, thereby driving the placing platform 33 to move up and down.

[0025] As shown: Figure 2 A plurality of rollers 5 are installed on the placing platform 33 and the frame 1; through the above setting, the rollers 5 can more conveniently move the compartment body 4, and can quickly move the compartment body 4 on the placing platform 33 and the frame 1.

[0026] As shown: Figure 3 And Figure 5 As shown: a fixing hole 6 is formed in the rear end of the frame 1, which cooperates with the push-pull type presser 8 to fix the position of the support 2; through the above setting, when the support 2 is rotated 90° and stands on the rear of the frame 1, the fixing pin on the push-pull type presser 8 can be inserted into the inside of the fixing hole 6, and then the position of the support 2 is limited.

[0027] Working principle: when the compartment body 4 needs to be replaced, first, separate the fixing pin of the push-pull type presser 8 from the fixing hole 6, then place the support 2 in the vertical state flat, and control the lifting mechanism 3 through the hydraulic oil cylinder 32 to make the placing platform 33 horizontal with the frame 1. Then push the compartment body 4 to move it from the frame 1 to the placing platform 33, then control the lifting mechanism 3 to descend, so that the universal wheel at the bottom of the compartment body 4 contacts the ground, thereby moving away the compartment body 4 and replacing another compartment body 4.

[0028] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
