[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the embodiments of the present invention.

[0030] Example 1

[0031] like Figure 1-5As shown, the utility model provides a technical solution: an electric vehicle frame that is convenient for installing and replacing batteries, including a frame body 1, a mounting groove 101 is opened at the top of the frame body 1, a slide groove 2 is symmetrically opened on the inner side wall of the mounting groove 101, a slider 201 is set inside the slide groove 2, the slider 201 can slide inside the slide groove 2, a cylinder 202 is fixed on the inner side wall of the slide groove 2 and passes through the slider 201, and a spring 20 is sleeved on the outer periphery of the cylinder 202 and located between the inner bottom surface of the mounting groove 101 and the slider 201. 3. The spring 203 can lift the slider 201. A carrying plate 204 is fixed between the sliders 201. The carrying plate 204 is used to carry the battery. A fixing plate 3 is installed on the inner wall of the installation groove 101 and at the top of the slide groove 2. A telescopic airbag 301 is installed at the bottom center of the fixing plate 3. The fixing plate 3 and the telescopic airbag 301 can fix the battery. A handle 302 is installed on the top of the fixing plate 3. A card slot 303 is symmetrically opened on the outer wall of the fixing plate 3. The card block 104 can be stuck inside the card slot 303.

[0032] Example 2

[0033] like Figure 1-5 As shown, the slider 201 is slidably connected to the slide groove 2, and the slider 201 is adapted to the spring 203. Through the sliding connection between the slider 201 and the slide groove 2 and the adaptation of the slider 201 to the spring 203, the slider 201 can slide and displace inside the slide groove 2, and the spring 203 can push the slider 201.

[0034] The slider 201 and the supporting plate 204 are fixed by welding, which can make the fixing by welding more firm.

[0035] A through hole 205 is provided at the top of the slider 201 corresponding to the cylinder 202 , and the through hole 205 is slidably connected to the cylinder 202 . The sliding connection between the through hole 205 and the cylinder 202 ensures that the slider 201 will not be affected by the cylinder 202 during displacement.

[0036] The telescopic airbag 301 is made of rubber material and is bonded and fixed to the fixing plate 3. The telescopic airbag 301 made of rubber material can play a good buffering role, effectively protect the battery, and has a long service life.

[0037] The handle 302 is of a hidden design, and the handle 302 is fixed to the fixing plate 3 by bolts. The hidden design of the handle 302 can effectively save the use space inside the frame body 1.

[0038] A groove 102 is provided on the inner side wall of the installation groove 101 at a position corresponding to the card slot 303. A telescopic rod 103 is installed inside the groove 102. A clamping block 104 is fixed to one end of the telescopic rod 103 close to the card slot 303. Through the design of the telescopic rod 103, the telescopic rod 103 can drive the clamping block 104 to extend and retract, thereby facilitating the installation and removal of the fixing plate 3.

[0039] The clamping block 104 is a spherical clamping block, which is adapted to the clamping slot 303 . The clamping block 104 is adapted to the clamping slot 303 so that the clamping block 104 can be clamped inside the clamping slot 303 to install and fix the fixing plate 3 .

[0040] The working process of the present invention is as follows: when replacing the battery of an electric vehicle frame that is easy to install and replace batteries, the staff can first pull the fixing plate 3 through the handle 302, so that the telescopic rod 103 can drive the block 104 to retract, thereby separating the block 104 from the slot 303. At this time, the staff can lift the fixing plate 3 more conveniently, and the spring 203 can push up the slider 201 at this time. When the slider 201 moves, the supporting plate 204 and the battery are lifted together. After the original battery is taken out, the new battery can be directly placed on the supporting plate 204. After the battery is connected to the input end of the electric vehicle, the fixing plate 3 is covered so that the block 104 can be re-engaged in the slot 303 to complete the replacement of the battery. Compared with the existing electric vehicle frame, it is more convenient to replace the battery when it is needed, and the operation steps are relatively simple, which greatly improves the efficiency of replacing the battery.

[0041] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of this utility model patent shall be determined by the appended claims.
