The output shaft of the motor is provided with a gear. The transmission chain installed on the fixed plate drives the middle plate to slide in the front and rear directions through the electric component. At the same time, the outer plate is synchronously followed by the middle plate through the transmission chain. The first roller is installed on the crossbeam fixed to the outer plate for temporarily storing batteries.

[0009] The charging mechanism comprises a control cabinet, a battery carrying frame and a second roller, wherein the control cabinet and the second roller are mounted and fixed on the battery carrying frame, and the battery carrying frame is divided into at least two groups of battery positions, namely, a potential changing position and a charging position;

[0010] The first slider of the battery grabbing mechanism is engaged with the first guide rail of the mobile platform, and the gear on the output shaft of the electric component is meshed with the rack on the mobile platform; when the battery grabbing mechanism approaches the battery, the battery grabbing component moves up and down and engages and disengages with the fixing frame.

[0011] Furthermore, the battery grabbing component is composed of a mounting plate, a second guide rail, a second slider, a cylinder assembly, a cylinder assembly mounting plate and a grabbing plate. The grabbing plate matches the locking structure of the battery, and the second slider on the grabbing plate is engaged with the second guide rail mounted on the mounting plate; the cylinder assembly is fixed on the cylinder assembly mounting plate, and the other end of the cylinder assembly is fixed to the grabbing plate; the cylinder assembly mounting plate is installed and fixed on the mounting plate, and when the piston rod of the cylinder assembly is raised or lowered, the grabbing plate connected to the second guide rail is driven to move up and down, and the grabbing plate is engaged and disengaged with the fixing frame.

[0025] The battery replacement and charging device of this embodiment for electric forklifts and electric stackers is as follows: Figure 1 As shown, the device includes a mobile platform 3, a battery grabbing mechanism 2 and a charging mechanism 1.

[0026] like Figure 1 and Figure 3 As shown, the mobile platform 3 includes a carrying frame 3-1, a first guide rail 3-2 and a rack 3-3.

[0027] like Figure 1 and Figure 4As shown, the battery grabbing mechanism 2 is designed based on the size of the battery 4, and includes a fixed plate 2-1, a middle plate 2-2, an outer plate 2-3, a battery grabbing component 2-4, a crossbeam 2-5, an electric component 2-6, a first roller 2-7, a telescopic guide rail 2-8, a transmission chain 2-9 and a first slider 2-10. The fixed plate 2-1 is divided into two left and right parts and connected to each other through the crossbeam. The fixed plate 2-1 is installed on the guide rail 3-2 through the first slider 2-10. The fixed plate 2-1, the middle plate 2-2 and the outer plate 2-3 are sequentially connected together through the telescopic guide rail 2-8. The electric component 2-6 includes a motor and a reducer, and a gear is provided on the output shaft of the motor. The transmission chain 2-9 installed on the fixed plate 2-1 slides in the front-back direction through the electric assembly 2-6 and its driving middle plate 2-2, and the outer plate 2-3 moves synchronously with the middle plate 2-2 through the transmission chain 2-9. The first roller 2-7 is installed on the crossbeam 2-5 fixed to the outer plate 2-3 and is used to temporarily store the battery 4;

[0028] like Figure 1 and Figure 2 As shown, the charging mechanism 1 includes a control cabinet 1-1, a battery carrying frame 1-2 and a second roller 1-3. The control cabinet 1-1 and the second roller 1-3 are installed and fixed on the battery carrying frame 1-2. The battery carrying frame 1-2 is divided into three groups of battery positions, namely, potential change position, charging position and transfer position.

[0029] The first slider 2-10 of the battery grasping mechanism 2 is engaged with the first guide rail 3-2 of the mobile platform 3, and the gear on the output shaft of the electric component 2-6 on the battery grasping module 2 is engaged with the rack 3-3 on the mobile platform 3, so that the battery grasping mechanism 2 is moved on the mobile platform 3 through the motor drive of the electric component 2-6.

[0030] like Figure 4 , Figure 5 and Figure 6As shown, the battery grabbing component 2-4 is fixed on the outer plate 2-3 through the mounting plate 2-41, and is used to grab the battery 4 for battery replacement and charging. The battery grabbing component 2-4 is composed of a mounting plate 2-41, a second guide rail 2-42, a second slider 2-43, a cylinder assembly 2-44, a cylinder assembly mounting plate 2-45 and a grabbing plate 2-46. The design of the grabbing plate 2-46 matches the battery fixing frame 41, and the second slider 2-43 installed on the grabbing plate 2-46 is engaged with the second guide rail 2-42 installed on the mounting plate 2-41; the cylinder assembly 2-44 is fixed on the cylinder assembly mounting plate 2-45, and the other end of the cylinder assembly 2-44 is fixed to the grabbing plate 2-46; the cylinder assembly mounting plate 2-45 is installed and fixed on the mounting plate 2-41; when the piston rod of the cylinder assembly 2-44 is raised or lowered, the grabbing plate 2-46 connected to the second guide rail 2-42 can be driven to move up and down, and the grabbing plate 2-46 can be engaged and disengaged with the fixing frame 41 on the battery 4, so as to smoothly grab the battery 4 for battery replacement or charging.

[0031] like Figure 7 As shown, the battery 4 is taken and placed on the electric forklift and the electric stacker in a pull-out manner, and a fixing frame 41 is provided on the battery 4 .

[0032] The process of using the device of this embodiment is as follows:

[0033] Step 1: When the system detects that the battery 4 used by the electric forklift and the electric stacker has run out of power and needs to be replaced, the electric forklift and the electric stacker are first moved to the area where the device of this embodiment is located, so that the device of this embodiment is close to the electric forklift or the electric stacker, and the charging position of the charging mechanism 1 of the device of this embodiment is aligned with the run-out battery 4 on the electric forklift or the electric stacker;

[0034] Step 2: The battery grabbing mechanism 2 moves to the charging position of the charging mechanism 1 first, and the piston rod of the cylinder assembly 2-44 on the battery grabbing component 2-4 drives the grabbing plate 2-46 to rise to the upper limit position, and the outer plate 2-3 on the battery grabbing mechanism 2 drives the battery grabbing component 2-4 to extend to (close to) the fixing frame 41 position of the exhausted battery 4, such as Figure 8 As shown; the piston rod of the cylinder assembly 2-44 on the battery grabbing component 2-4 drives the grabbing plate 2-46 to descend, and the grabbing plate 2-46 grabs the fixing frame 41 of the exhausted battery 4 (the grabbing plate 2-46 and the fixing frame 41 are engaged with each other), and then the fixing frame 41 of the exhausted battery 4 is manually released from the fixed relationship of the battery placement position of the electric forklift or electric stacker, and the outer plate 2-3 on the battery grabbing mechanism 2 drives the battery grabbing component 2-4 and the exhausted battery 4 back to the first roller 2-7 of the battery grabbing mechanism 2;

[0035] Step 3: The outer plate 2-3 on the battery grabbing mechanism 2 drives the battery grabbing component 2-4 to deliver the exhausted battery 4 to the second roller 1-3 of the charging position on the charging mechanism 1; the piston rod of the cylinder assembly 2-44 on the battery grabbing component 2-4 drives the grabbing plate 2-46 to rise, and the grabbing plate 2-46 is detached from the adjacent fixing frame 41 of the exhausted battery 4, and the exhausted battery 4 is fixed on the second roller 1-3 of the charging position; then the charging wire head in the control cabinet 1-1 is manually connected to the exhausted battery 4 for charging, and of course, the charging wire head in the control cabinet 1-1 can also be automatically connected to the exhausted battery 4 for charging;

[0036] Step 4: The battery grabbing mechanism 2 moves to the potential-changing position on the charging mechanism 1; the outer plate 2-3 on the battery grabbing mechanism 2 drives the battery grabbing component 2-4 to extend to (close to) the position of the fixing frame 41 of another charged battery 4 on the second roller 1-3 of the power-changing mechanism 1; the piston rod of the cylinder assembly 2-44 on the battery grabbing component 2-4 drives the grabbing plate 2-46 to descend, and the grabbing plate 2-46 grabs the fixing frame 41 of the charged battery 4 (the grabbing plate 2-46 and the fixing frame 41 are engaged with each other again), and the charged battery 4 is manually released from the fixed relationship of the second roller 1-3 position for potential change; the outer plate 2-3 on the battery grabbing mechanism 2 drives the battery grabbing component 2-4 and the charged battery 4 to return to the first roller 2-7 of the battery grabbing mechanism 2;

[0037] Step 5: The outer plate 2-3 on the battery grabbing mechanism 2 drives the battery grabbing component 2-4 and the charged battery 4 to the battery placement position on the electric forklift and the electric stacker; the piston rod of the cylinder assembly 2-44 on the battery grabbing component 2-4 drives the grabbing plate 2-46 to rise, and the grabbing plate 2-46 detaches from the nearby fixed frame 41 of the charged battery 4, and the charged battery 4 is fixed on the electric forklift and the electric stacker through the fixed frame 41; the battery grabbing mechanism 2 is reset, and the entire battery replacement process is completed.

[0038] The above process is for the case where one battery needs to be charged and the other battery has been charged. Of course, if there are three batteries, the battery grabbing mechanism 2 can first move the low-power battery 4 to the intermediate transfer position on the charging mechanism 1 and pause, and then move to the charging position on the charging mechanism 1, or move the battery that has been charged at the charging position on the charging mechanism 1 to the intermediate transfer position on the charging mechanism 1 and pause. The process of the battery grabbing mechanism 2 grabbing the battery 4 and moving it to different positions on the charging mechanism 1 is similar to the above process and will not be repeated here.

[0039] Obviously, in addition to the case of switching two or three batteries considered in this embodiment, the case of switching four or more batteries may also be involved, and the case is similar to that in this embodiment and will not be described in detail here.

[0040] The present invention is not limited to the above-mentioned embodiments, and any technical solutions formed by equivalent replacement shall fall within the protection scope required by the present invention.
