[0057] Screw 901, threadedly connected to the driving plate 9;

[0058] The pressing plate 8 is fixedly connected to the bottom of the screw rod 901;

[0059] The driving plate 9 rotates to drive the screw rod 901 to rotate, and the screw rod 901 synchronously drives the pressing plate 8 to flip, and the lower surface of the pressing plate 8 presses on the upper surface of the upper base 1.

[0060] Reference Figure 7 A connector 1001 is fixedly connected to the bottom of the box body 10, and the connector 1001 is fixedly welded to the upper base 1; the upper base 1 and the lower base 2 are provided with corresponding electrical plug-in interfaces.

[0061] Reference Figure 1-Figure 4 , Figure 7 During installation, a lifting machine is used to lift the box 10 fixedly connected to the upper base 1, and the lifted box 10 is transported to the top of the lower base 2, and the upper base 1 and the box 10 are moved downward. After the upper base 1 moves downward for a certain distance, the upper base 1 will contact the first positioning wheel 301 and the second positioning wheel 501. At this time, under the action of the downward pressure and friction of the upper base 1 and the box 10, the first positioning wheel 301 and the second positioning wheel 501 will rotate, and the upper base 1 will adjust and slide, thereby completing the center positioning;

[0062] Reference Fig. 9 The support plate 201 is fixedly connected to a second support seat 12, the second support seat 12 is rotatably connected to a rotating plate 1201, the rotating plate 1201 is fixedly connected to a driving cylinder 6, the driving cylinder 6 is slidably connected to a driving rod 602, the first support seat 13 is rotatably connected to a pulling plate 11, the pulling plate 11 is rotatably connected to a connecting plate 14, the connecting plate 14 is rotatably connected to the driving plate 9, the pulling plate 11 is fixedly connected to a connecting rod 1101, the connecting rod 1101 is rotatably connected to a connecting head 6021, and the connecting head 6021 and the driving rod 602 are fixedly connected.

[0063] A first sliding plug 603 is slidably connected in the driving cylinder 6 , and the first sliding plug 603 is fixedly connected to the driving rod 602 . A third air delivery pipe 604 is fixedly connected to the side wall of the driving cylinder 6 .

[0064] It should be noted that the third air supply pipe 604 can be connected to the air pump on the electric truck to inflate and deflate the driving cylinder 6.

[0065] After the positioning is completed, gas is input into the driving cylinder 6, thereby pushing the first sliding plug 603 to slide, thereby pushing the driving rod 602 to slide, and thereby pushing the driving plate 9 to rotate. The rotation of the driving plate 9 will drive the pressure plate 8 to rotate. After the pressure plate 8 rotates a certain angle, the pressure plate 8 will abut against the upper surface of the upper base 1, thereby pressing the upper base 1, thereby completing the limit fixation of the upper base 1, thereby ensuring that the upper base 1 will not have horizontal deviation during installation, thereby ensuring the installation accuracy.

[0066] A U-shaped rod 4 is fixedly connected to the lower base 2, an air bag 401 is fixedly connected in the U-shaped rod 4, a first air pipe 601 is fixedly connected to the side wall of the driving cylinder 6, the first air pipe 601 is connected to the air bag 401, and a pressure sensor 4011 is connected in the air bag 401.

[0067] The pressure sensor 4011 is an electronic sensor available on the market and can be connected to an external computer. When the pressure data of the pressure sensor 4011 is uploaded to the computer, the staff can judge whether the upper base 1 has horizontal deviation during positioning and installation based on the values ​​of each group of pressure sensors 4011.

[0068] Reference Figure 4 , Figure 6 , Figure 8 and Fig. 9 When the first sliding plug 603 slides, the sliding first sliding plug 603 pushes out the gas in the driving cylinder 6, and the pushed out gas is input into the airbag 401 through the first air delivery pipe 601. The airbag 401 is inflated and bulges and abuts against the inner wall of the upper base 1. At this time, the staff can observe the value of the pressure sensor 4011 in each group of airbags 401;

[0069] When the value of the left pressure sensor 4011 is greater than the value of the right pressure sensor 4011, the upper base 1 is horizontally deviated to the right compared to the lower base 2, and the staff can manually fine-tune the upper base 1 to the left;

[0070] When the value of the left pressure sensor 4011 is smaller than the value of the right pressure sensor 4011, the upper base 1 is horizontally deviated to the left compared to the lower base 2, and the staff can manually fine-tune the upper base 1 to the right;

[0071] During the adjustment process, the staff can observe the values ​​of the pressure sensors 4011 on both sides while adjusting. When the values ​​of the pressure sensors 4011 on the left and right sides are the same, the upper base 1 and the lower base 2 are installed in the center positioning.

[0072] It should be noted that an air inlet pipe is also connected to the side wall of the driving cylinder 6 , and the air inlet pipe and the third air supply pipe 604 are symmetrically arranged up and down to replenish gas to the upper space of the first sliding plug 603 in the driving cylinder 6 .

[0073] It should also be noted that one-way valves are provided on the air inlet pipe, the third air supply pipe 604 and the first air supply pipe 601 .

[0074] It should be further explained that the shapes and specifications of the driving cylinders 6 of each group are the same, and when in use, the amount of gas output through the first gas pipe 601 is the same, so as to ensure that the amount of gas input into the airbag 401 is the same, so as to improve the detection accuracy of the airbag 401;

[0075] It should be further explained that the airbags 401 are commercially available directional expansion airbags, and each group of airbags 401 has the same model and specification; the initial air storage volume in each group of airbags 401 is equal.

[0076] By using a directional expansion bag as the airbag 401, it can be ensured that the airbag can stably extend laterally and abut against the inner wall of the upper base 1 when inflated, thereby ensuring the accuracy of the deviation detection.

[0077] A sliding cavity 7 is provided in the lower base 2, and a limit pin 701 is slidably connected in the sliding cavity 7. A first magnet 7011 is fixedly connected to the limit pin 701, and a second magnet 801 is fixedly connected to the pressure plate 8. The first magnet 7011 and the second magnet 801 attract each other.

[0078] A second sliding plug 702 is slidably connected in the sliding cavity 7 , a second air pipe 704 is fixedly connected to the U-shaped rod 4 , one end of the second air pipe 704 is connected to the airbag 401 , and the other end of the second air pipe 704 is connected to the sliding cavity 7 .

[0079] It should be noted that the second gas supply pipe 704 is provided with a commercially available one-way pressure relief valve.

[0080] Reference Figure 5 , Figure 8 , Fig. 9 After the positioning and installation is completed, the second magnet 801 extends into the limiting hole 101, and the pressure relief valve on the second air pipe 704 is opened. The gas in the airbag 401 will be sprayed into the sliding cavity 7 through the second air pipe 704. The gas entering the sliding cavity 7 will push the second sliding plug 702 to slide up, and the sliding of the second sliding plug 702 will push the limiting pin 701 to move up. After the limiting pin 701 moves up a certain distance, the first magnet 7011 will be attracted by the second magnet 801 and move up quickly, thereby pulling the limiting pin 701 to move up quickly. After the first magnet 7011 and the second magnet 801 are attracted to each other, the upper base 1 and the lower base 2 can be further fixedly installed through the limiting pin 701.

[0081] It should be noted that both the first magnet 7011 and the second magnet 801 are strong magnets to ensure the limiting stability of the limiting pin 701 .

[0082] An elastic pull rope 703 is fixedly connected to the bottom of the second sliding plug 702 , and one end of the elastic pull rope 703 away from the second sliding plug 702 is fixedly connected to the bottom wall of the sliding cavity 7 .

[0083] It should be noted that a pressure relief valve is connected to the side wall of the lower base 2 , and the pressure relief valve is communicated with the sliding cavity 7 .

[0084] It should also be noted that the pressure relief valve is a solenoid valve available on the market.

[0085] Reference Figure 5 Through the elastic pull rope 703 set in the sliding cavity 7, when the pressure relief valve is opened to discharge the gas in the sliding cavity 7, the elastic pull rope 703 can pull the second sliding plug 702 to quickly reset, and then the limiting pin 701 can be pulled out of the limiting hole 101.

[0086] A limiting ring 705 is fixedly connected to the lower base 2 , and the limiting ring 705 abuts against the second sliding plug 702 .

[0087] Reference Figure 5 By means of the limiting ring 705 disposed on the lower base 2 , when the limiting pin 701 moves upward, the second sliding plug 702 will not slide excessively and disengage from the sliding cavity 7 .

[0088] The first gas delivery pipe 601 and the second gas delivery pipe 704 are both elastic hoses.

[0089] Embodiment 2:

[0090] A method for using a multi-environment quick-release battery box, the steps are as follows:

[0091] Step 1: Use a hoisting machine to lift the box 10 fixedly connected to the upper base 1;

[0092] Step 2: transport the lifted box 10 to above the lower base 2;

[0093] Step 3: Move the upper base 1 and the box 10 downward;

[0094] Step 4: The upper base 1 contacts the first positioning wheel 301 and the second positioning wheel 501, and the first positioning wheel 301 and the second positioning wheel 501 rotate to drive the upper base 1 to be positioned on the lower base 2;

[0095] Step 5: Input gas into the driving cylinder 6 to push the driving rod 602 to slide out, the driving rod 602 pushes the driving plate 9 to rotate, and the driving plate 9 drives the pressing plate 8 to press the upper base 1;

[0096] Step 6: The gas in the driving cylinder 6 is input into the airbag 401, and the airbag 401 is inflated and bulges against the upper base 1;

[0097] Step 7: Observe and compare the values ​​of the pressure sensors 4011 in the multiple groups of airbags 401 to determine the positioning and installation accuracy of the box body 10 and the upper base 1;

[0098] Step eight, the gas in the airbag 401 is input into the sliding cavity 7 through the second gas pipe 704, pushing the limit pin 701 to move upward, and the first magnet 7011 on the limit pin 701 is attracted to the second magnet 801 on the pressure plate 8, completing the limit installation of the upper base 1 and the lower base 2.

[0099] Reference Figure 1-Figure 9 During disassembly, the gas in the driving cylinder 6 is extracted through the third air pipe 604. At this time, the first sliding plug 603 is pulled to reset, and then the driving rod 602 is pulled to reset. At this time, the driving rod 602 will pull the pressure plate 8 to flip and reset, thereby releasing the downward pressure on the upper base 1. At the same time, the second magnet 801 on the pressure plate 8 will separate from the first magnet 7011 on the limit pin 701. After each group of pressure plates 8 is reset, the box body 10 and the upper base 1 can be lifted away by the crane to complete the disassembly.

[0100] When installing the box 10 with the upper base 1, the upper base 1 can be driven to slide and position by the multiple sets of positioning wheels provided on the device, thereby completing the positioning installation between the upper base 1 and the lower base 2, and the upper base 1 can be pressed tightly by the driving cylinder 6 provided in the device by pushing the pressing plate 8. At the same time, the driving cylinder 6 can also inflate the airbag 401, and by observing the pressure value in the airbag 401, it can be determined whether the upper base 1 has a horizontal deviation during the positioning installation;

[0101] Finally, the gas in the airbag 401 in the device is discharged to push the second sliding plug 702 to move, thereby driving the limit pin 701 to move. The limit pin 701 cooperates with the pressure plate 8 to complete the fixed installation of the upper base 1 and the lower base 2, thereby ensuring the stability and accuracy of the upper base 1 after installation.

[0102] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.

A method for using the multi-environment quick-release battery box according to claim 4, characterized in that: Here are the steps: Step 1: Use a hoist to lift the box that is fixed on the upper base; Step 2: transport the lifted box to the top of the lower base; Step 3: Move the upper base and the box downwards; Step 4: The upper base contacts the first positioning wheel and the second positioning wheel, and the first positioning wheel and the second positioning wheel position the upper base, and the upper base is positioned and adjusted to be attached to the lower base; Step 5: Input gas into the driving cylinder to push the driving rod to slide out, the driving rod pushes the driving plate to rotate, and the driving plate drives the pressing plate to press the upper base; Step 6: The gas in the driving cylinder is input into the airbag, and the airbag is inflated and bulges against the inner wall of the upper base; Step 7. Observe and compare the values ​​of the pressure sensors in multiple groups of airbags. If the values ​​of the airbags on the left and right sides are different, it means that the left and right side walls of the upper base squeeze the airbags to different degrees, so as to judge the positioning and installation accuracy of the box and the upper base; Step 8: The gas in the airbag is input into the sliding cavity through the second air delivery pipe, pushing the limit pin to move upward, and the first magnet on the limit pin is attracted to the second magnet on the pressure plate, completing the limit installation of the upper base and the lower base.
