[0042] The opening mechanism 12 includes a second connecting block 121, a second fixing block 122, a sixth connecting rod 123, a third spring 124, an inclined rod 125 and a fourth spring 126, see Fig.11 and Fig.12 As shown, a second connecting block 121 is welded to the outer rear part of the fifth connecting rod 103, a second fixed block 122 is provided on the inner side of the upper front side of the first connecting block 7, a sixth connecting rod 123 is slidably provided on the inner side of the upper front side of the first connecting block 7, the sixth connecting rod 123 is located on the outer side of the second fixed block 122, a third spring 124 is provided between the top of the sixth connecting rod 123 and the second fixed block 122 on the same side, an inclined rod 125 is provided at the lower part of the sixth connecting rod 123, and the second connecting block 121 will contact the inclined rod 125 when moving backward, and a fourth spring 126 is provided between the outer rear part of the placing plate 8 and the first connecting block 7 on the same side, and the placing plate 8 can be propped open under the elastic force of the fourth spring 126.

[0043] In the initial state, the fourth spring 126 is in a stretched state. When people need to use the new energy vehicle loading and lifting device, they first hold the first handle 4, and then push the first handle 4 to move. Under the action of the rotating wheel 1 and the universal wheel 104, the new energy vehicle loading and lifting device is driven to move to the position of the box, so that the placement plate 8 moves to the lower side of the box. When the rubber block 105 contacts the box, the box will squeeze the rubber block 105 to move backward, thereby driving the fifth connecting rod 103 and the second connecting block 121 to move backward, and the first spring 102 is compressed. When the box contacts the sixth connecting plate 113, the box squeezes the sixth connecting plate 113 to move backward, and the second spring 112 is compressed, thereby driving the bent rack 114 to move backward. When the curved rack 114 contacts the second gear 116, the curved rack 114 drives the second gear 116 to rotate, thereby driving the connecting shaft 115 to rotate, and the connecting shaft 115 drives the limiting plate 119 to rotate through the pulley 117 and the flat belt 118, so that the limiting plate 119 limits the box, and when the second connecting block 121 contacts the inclined rod 125, the second connecting block 121 squeezes the inclined rod 125 to move upward, thereby driving the sixth connecting rod 123 to move upward, and the third spring 124 is compressed. When the sixth connecting rod 123 is separated from the first connecting block 7, the sixth connecting rod 123 releases the placement plate 8. At this time, under the elastic force of the fourth spring 126, the fourth spring 126 drives the placement plate 8 to move outward, thereby opening the placement plate 8, and then Then, the switch 91 on the left is pressed to turn on the servo motor 92, so that the output shaft of the servo motor 92 rotates forward, and then the lead screw 96 rotates forward, so that the nut 97 and the third connecting plate 99 move upward, thereby driving the first gear 95 on the outside to rotate, so that the fourth connecting plate 910 moves upward, thereby driving the first gear 95 on the inside to rotate, so that the fifth connecting plate 911 moves upward, thereby driving the third connecting rod 98, the first connecting block 7 and the placement plate 8 to move upward, and then driving the box to move upward. When the box is separated from the rubber block 105, the first spring 102 returns to its original state, and the first spring 102 drives the fifth connecting rod 103, the rubber block 105 and the second connecting block 121 to move forward and reset. When the second connecting block 121 and the inclined rod 12 5 is separated, the third spring 124 returns to its original state, and the third spring 124 drives the sixth connecting rod 123 and the inclined rod 125 to move downward and reset. When the box is raised to a certain height, release the switch 91 on the left to turn off the servo motor 92, then step on the pedal 5 with both feet, and then turn on the double-axis motor 21. The output shaft of the double-axis motor 21 drives the rotating wheel 1 to rotate, thereby driving the new energy vehicle-based box loading and lifting device to move to a specified position, thereby driving the box to move, and then turn off the double-axis motor 21 to stop the new energy vehicle-based box loading and lifting device from moving, then remove both feet from the pedal 5, and then press the switch 91 on the right to turn on the servo motor 92, thereby reversing the output shaft of the servo motor 92, thereby driving the screw rod 96 to reverse.The nut 97 and the third connecting plate 99 are moved downward and reset, thereby driving the outer first gear 95 to reverse, the fourth connecting plate 910 is moved downward and reset, thereby driving the inner first gear 95 to reverse, and the fifth connecting plate 911 is moved downward and reset, thereby driving the third connecting rod 98, the first connecting block 7 and the placement plate 8 to move downward and reset. Under the action of gravity, the box moves downward. When the box contacts the fifth connecting rod 103, the fifth connecting rod 103 will block the box from moving downward, so that the box stops on the fifth connecting rod 103, and then release the switch 91 on the right to turn off the servo motor 92, and then pull the sixth connecting rod 123 to move upward, the third spring 124 is compressed, and then the placement plate 8 is pushed to move inward and reset, the fourth spring 126 is stretched, and then the sixth connecting rod 123 is released, and the third spring 124 is compressed. 124 returns to its original state, the third spring 124 drives the sixth connecting rod 123 to move downward and reset, so that the sixth connecting rod 123 is stuck on the placement plate 8, and then the placement plate 8 is released, and then the box is pushed forward manually. When the box is separated from the sixth connecting plate 113, the second spring 112 returns to its original state, and the second spring 112 drives the sixth connecting plate 113 and the curved rack 114 to move forward and reset. At this time, the curved rack 114 drives the second gear 116 to reverse, thereby driving the connecting shaft 115 to reverse, and the connecting shaft 115 drives the limit plate 119 to reverse and reset through the pulley 117 and the flat belt 118. When the curved rack 114 is separated from the second gear 116, the second gear 116, the connecting shaft 115 and the limit plate 119 stop rotating. When people push the box out of the fifth connecting rod 103, they can release the first handle 4.

[0044] Example 2

[0045] On the basis of the embodiment 1, a push mechanism 13 is further included. The push mechanism 13 includes a push plate 131, a seventh connecting rod 132, a second handle 133 and a support block 134. Figure 1 , Fig.13 and Fig.14 As shown, support blocks 134 are provided at the lower parts of the left and right sides of the third connecting rod 98, and seventh connecting rods 132 are slidably provided on the outer sides of the support blocks 134. A push plate 131 is provided between the front sides of the seventh connecting rod 132. When the push plate 131 moves forward to contact with the box, it can push the box to move. Second handles 133 are provided on the left and right sides of the push plate 131, and the second handles 133 are covered with rubber covers.

[0046] When people need to push the box forward, they can hold the second handle 133 with their hands. At this time, the rubber cover on the second handle 133 can increase the friction between the hand and the hand to prevent the hand from slipping. Then, the second handle 133 is pushed forward, thereby driving the push plate 131 to move forward. When the push plate 131 contacts the box, the push plate 131 drives the box forward. After people push the box from the fifth connecting rod 103, they pull the second handle 133 backward to reset, thereby driving the push plate 131 to move backward to reset, and then release the second handle 133, which makes it convenient for people to push the box forward.

[0047] The placing mechanism 14 is also included. The placing mechanism 14 includes a support plate 141, a placing frame 142, a cover plate 143 and an eighth connecting rod 144. Figure 1 and Fig.15 As shown, support plates 141 are welded to the upper parts of the left and right sides of the second connecting plate 93, and a placement frame 142 is provided on the top of the support plate 141. People can put tools into the placement frame 142 for storage, which is convenient for people to take out the tools for use. A cover plate 143 is placed on the top of the placement frame 142, and an eighth connecting rod 144 is provided in the middle of the top of the cover plate 143. When the third connecting plate 99 moves upward, it will contact the eighth connecting rod 144.

[0048] When the third connecting plate 99 moves upward to contact the eighth connecting rod 144, the third connecting plate 99 drives the eighth connecting rod 144 to move upward, thereby driving the cover plate 143 to move upward, and then people can put commonly used tools into the placement frame 142 or take commonly used tools out of the placement frame 142. When the third connecting plate 99 moves downward to separate from the eighth connecting rod 144, under the action of gravity, the eighth connecting rod 144 and the cover plate 143 move downward and reset, thereby making it convenient for people to store and take out the tools.
