[0044] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0045] First see Figure 1 , Figure 1 This is a schematic diagram of the structure of an embodiment of the highly integrated battery replacement device of the utility model. Figure 1 As shown, the highly integrated battery replacement device includes an upper loading mechanism 1 and a lower loading mechanism 2 connected to each other. The upper loading mechanism 1 is used for locking and unlocking the battery pack and placing and removing the battery pack. The lower loading mechanism 2 is used for lifting, transporting and rotating the upper loading mechanism 1 carrying the battery pack.

[0046] See next Figure 2 and Figure 3 , Figure 2 It is a structural schematic diagram of an embodiment of a load-bearing plate of the utility model; Figure 3 FIG. 1 is a schematic diagram of the structure of an embodiment of the toggle assembly of the utility model. Figure 2 As shown, the upper mounting mechanism 1 may include an upper mounting support plate 11 connected to the lower mounting mechanism 2, and a bearing plate 12 is slidably provided on the upper mounting support plate 11. A bearing frame 13 for carrying a battery pack is provided on the bearing plate 12. A plurality of toggle assemblies 14 may be provided on both sides of the upper mounting support plate 11. The toggle assemblies 14 are used to lock and unlock the locking rod of the battery pack at the vehicle end.

[0047] It should be noted that a plurality of connecting posts are usually provided on both sides of the battery pack, and the connecting posts are usually matched with the inverted L-shaped slots of the vehicle-end battery pack fixing frame. In addition, when the battery pack and the vehicle-end battery pack fixing frame are in a locked state, in order to prevent the connecting posts and the slots from sliding, a slidable vehicle-end battery pack locking rod is usually provided on the vehicle-end battery pack fixing frame and buckled onto the connecting posts. Therefore, when disassembling and assembling the battery pack, the vehicle-end battery pack locking rod needs to be controlled to complete locking and unlocking.

[0048] like Figure 3As shown, the above-mentioned toggle assembly 14 may include a first linear module and a toggle rod 141. The guide rail seat 144 of the first linear module may be fixedly connected to the side wall of the upper support plate 11. The first end ( Figure 3 The lower end of the first linear module (in the middle) may be provided with a strip groove 142. The strip groove 142 is slidably connected to the slider 143 of the first linear module. A fixing plate 145 may be provided on the guide rail seat 144 of the first linear module, and the lever 141 may be rotatably connected to the fixing plate 145 via a pivot axis. In this way, when the slider 143 of the first linear module slides, the second end ( Figure 3 The upper end of the battery pack (in the middle) rotates around the pivot axis, thereby toggling the vehicle-end battery pack locking rod to disengage or engage with the connecting column, thereby switching the locked state and unlocked state of the battery pack and the vehicle-end battery pack fixing frame.

[0049] Taking the removal of the battery pack as an example, when the battery pack and the vehicle-end battery pack fixing frame are in the unlocked state, the battery pack needs to be moved out of the horizontal section and the vertical section of the slot. Since the upper support plate 11 is slidably provided with a carrier plate 12, and the carrier plate 12 is provided with a carrier frame 13 for carrying the battery pack, when the carrier plate 12 moves relative to the upper support plate 11, the carrier frame 13 and the battery pack can be moved horizontally.

[0050] Re-read Figure 2 , the above-mentioned carrier plate 12 can be slidably connected to the upper support plate 11 through a track. The setting direction of the track is parallel to the horizontal section of the above-mentioned card slot. A second linear module can be set below the upper support plate 11, and the motor end 151 of the second linear module can be fixedly connected to the upper support plate 11. A hollow structure can be opened in the middle of the upper support plate 11, so that the slider 152 of the second linear module is connected to the bottom of the carrier plate 12. When the slider 152 of the second linear module moves, it can drive the carrier plate 12, the carrier frame 13 and the battery pack to slide relative to the upper support plate 11, so that the connecting column of the battery pack moves in the horizontal section of the card slot. Finally, after the lower loading mechanism 2 is lowered, the connecting column of the battery pack can be moved in the vertical section of the card slot, so that the battery pack is completely separated from the vehicle-end battery pack fixing frame, and the battery pack is disassembled.

[0051] Due to reasons such as body manufacturing errors, the slots of the battery pack fixing frame at the vehicle end may not be at the same height, which will cause the battery pack to tilt at a certain angle. Therefore, when removing the battery pack, as the lower installation mechanism 2 lifts the upper installation mechanism 1, the support frame 13 cannot be completely engaged with the bottom of the battery pack. After the battery pack is removed, the support frame 13 and the battery pack are prone to collision. When installing the battery pack, the connecting column of the battery pack cannot cooperate smoothly with the horizontal section of the slot, causing the battery pack to be unable to move, or scratching the connecting column when moving.

[0052] like Figure 2 As shown, in order to solve the above problems, a plurality of support blocks 161 are arranged on both sides of the carrier plate 12. The upper end of each support block 161 is connected to a support pad 162 through a spring. The support pad 162 can adjust the height pre-compression length through the spring when subjected to external force. In this way, when disassembling the battery pack, the plurality of support pads 162 can engage with the bottom of the battery pack. Even if the battery pack is tilted, the compression of the spring can make the plurality of support pads 162 fully engage with the bottom of the battery pack, thereby improving the reliability of the device. When installing the battery pack, as the battery pack rises, the plurality of springs are compressed to different degrees, so that the support pad 162 can cooperate with the horizontal section of the connecting column and the slot, so that the horizontal movement of the battery pack is not interfered. It should be noted that during the process of disassembling and assembling the battery pack, the upper surface of the above-mentioned support pad 162 is higher than the carrier 13.

[0053] See next Figure 4 , Figure 5 , Figure 6 and Figure 7 , Figure 4 It is a structural schematic diagram of an embodiment of a carrier frame of the utility model; Figure 5 It is a structural schematic diagram of an embodiment of a lifting assembly of the utility model; Figure 6 It is a structural schematic diagram of an embodiment of a side thrust drive assembly of the utility model; Figure 7 FIG. 2 is a schematic diagram of the structure of another embodiment of the side thrust drive assembly of the utility model. Figure 4 As shown, a support wheel assembly and a side push drive assembly 19 are also provided in the above-mentioned carrier 13. The above-mentioned support wheel assembly is used to lift or lower the carrier 13 relative to the carrier plate 12. The side push drive assembly 19 drives the carrier 13 to slide back and forth relative to the carrier plate 12 by extending and retracting. It should be noted that in order to show the side push drive assembly 19, Figure 4 The sheet metal used to support the battery pack is hidden.

[0054] That is to say, when placing the battery pack on the shelf, the support wheel assembly lifts the carrier 13 and the battery pack so that the upper end surface of the carrier 13 is higher than the support pad 162. The side push drive assembly 19 extends, so that the carrier 13 drives the battery pack to move relative to the carrier plate 12, so that it enters the shelf. After the support wheel assembly lowers the battery pack, the battery pack can be engaged with the shelf. Finally, the side push drive assembly 19 retracts to drive the carrier 13 back to the carrier plate 12.

[0055] like Figure 4 and Figure 5As shown, the above-mentioned support wheel assembly may include a plurality of lifting assemblies 171 arranged on both sides of the carrier 13, and each lifting assembly 171 may include a fixed portion 1711 and a movable portion 1712. The fixed portion 1711 is fixed to the carrier 13, and the movable portion 1712 is movably inserted below the fixed portion 1711. One or more rollers 1713 are arranged at the bottom of the movable portion 1712. The roller 1713 passes through the carrier 13 and abuts against the carrier plate 12, so that the carrier 13 can slide relative to the carrier plate 12 when the side push drive assembly 19 is extended and retracted through the roller 1713 whether it is lifted or dropped. When the movable portion 1712 is extended, the fixed portion 1711 drives the carrier 13 to move upward to achieve lifting. As an example, the above-mentioned lifting assembly 171 may be an electric push rod or an electromagnetic push rod provided with a roller 1713.

[0056] The plurality of lifting components 171 can also control the extension and retraction of the movable part 1712 through the third linear module 1721. Specifically, vertical strip holes 1714 can be provided on both sides of the fixed part 1711, and horizontal strip holes are provided at the bottom of the fixed part 1711. Slide bars are provided on both sides of the movable part 1712, and an oblique strip hole 1715 is provided at the bottom of the movable part 1712. In the assembled state, the two slide bars can be slidably provided in the two vertical strip holes 1714.

[0057] like Figure 4 As shown, the third linear module 1721 can be set on the bottom plate of the carrier frame 13, and the slider of the third linear module 1721 is connected with a transverse connecting plate 1722. The setting direction of the transverse connecting plate 1722 is perpendicular to the arrangement direction of the lifting components 171 on one side. Two transmission plates 1723 are also fixed on both sides of the transverse connecting plate 1722, and each transmission plate 1723 is arranged in parallel with multiple lifting components 171 on one side. Each transmission plate 1723 is provided with a transmission rod 1724 of the same number as the lifting components 171 on one side. The transmission rod 1724 can slide through the transverse strip hole and the oblique strip hole 1715.

[0058] When the slider of the third linear module 1721 moves, the transverse connecting plate 1722 can drive the two transmission plates 1723 to move synchronously. During this process, the transmission rod 1724 of the transmission plate 1723 can slide along the transverse strip hole, and the oblique strip hole 1715 and the transmission rod 1724 also slide relative to each other, so that the movable part 1712 moves up and down in the vertical direction under the restriction of the vertical strip hole 1714 and the sliding rod. When the movable part 1712 moves downward, the supporting frame 13 is lifted. When the height of the supporting frame 13 exceeds the support pad 162, the supporting frame 13 holds up the battery pack.

[0059] The driving method of the driving lifting assembly 171 can make the multiple movable plates extend and retract synchronously, which can reduce the control difficulty compared to the method of individually controlling the movable part 1712.

[0060] like Figure 4 As shown, one end of the side push drive assembly 19 is connected to the carrier 13, and the other end of the side push drive assembly 19 is connected to the carrier plate 12. When the side push drive assembly 19 is extended or retracted, the carrier 13 can slide relative to the carrier plate 12 through the roller 1713 of the lifting assembly 171. As an example, the side push drive assembly 19 can be an electric push rod.

[0061] In order to increase the extension distance of the side push drive assembly 19, the side push drive assembly 19 may include four push rods and four chains that are slidably connected. Figure 4 , Figure 6 and Figure 7 For explanation. Figure 4 and Figure 6 As shown, from top to bottom ( Figure 6 The four push rods are the first push rod 191, the second push rod 192, the third push rod 193 and the fourth push rod 194. The adjacent push rods are slidably connected to the slide rail through the slider. The first push rod 191 is fixedly connected to the carrier frame 13, and the right end ( Figure 6 direction in the middle) is connected to the carrying plate 12.

[0062] like Figure 6 As shown, the first end ( Figure 6 The upper layer of the left end of the sprocket wheel 1921 is provided. Figure 7 As shown, the second end ( Figure 7 The lower layer of the left end of the sprocket wheel 1922 is provided. Figure 6 As shown, the first end ( Figure 6 The lower layer of the left end of the third push rod 193 is provided with a third sprocket 1931. The second end ( Figure 6 A fourth sprocket 1932 is provided on the upper layer of the right end of the sprocket.

[0063] like Figure 6 As shown, the first chain 195 is meshed with the first sprocket 1921, and both ends are respectively connected to the first end ( Figure 6 The right end of the third push rod 193 and the first end of the third push rod 193 ( Figure 6 The left end of the connection. Figure 7 As shown, the second chain 196 is meshed with the second sprocket 1922, and both ends are respectively connected to the first end ( Figure 7The left end of the third push rod 193 and the first end of the third push rod 193 ( Figure 7 The right end of the connection. Figure 6 As shown, the third chain 197 is meshed with the third sprocket 1931, and both ends are respectively connected to the second end ( Figure 6 The right end of the fourth push rod 194 and the first end of the fourth push rod 194 ( Figure 6 The left end of the connection. Figure 6 As shown, the fourth chain 198 is meshed with the fourth sprocket 1932, and both ends are respectively connected to the second end ( Figure 6 The right end of the fourth push rod 194 and the first end of the fourth push rod 194 ( Figure 6 ) connected to the left end of the .

[0064] The side push drive assembly further includes a fourth linear module disposed in the carrier frame, wherein a slider 199 of the fourth linear module is connected to a first end ( Figure 6 left end of the ).

[0065] The side push drive assembly 19 further includes a fourth linear module set in the carrier 13, and a slider 199 of the fourth linear module is connected to the first end of the second push rod 192. Specifically, the slider 199 of the fourth linear module can be connected to the second push rod 192 via a connecting plate. The connecting plate can be slidably connected to a slide rail fixed to the carrier 13, thereby further limiting the sliding direction of the connecting plate.

[0066] Re-read Figure 4 And continue to read Figure 6 and Figure 7 When the slider 199 of the fourth linear module slides to the left, since the fourth push rod 194 is connected to the carrier plate 12, the second push rod 192 drives the first push rod 191, the carrier frame 13 and the third push rod 193 to slide to the left through the roller 1713. When the slider 199 of the fourth linear module slides to the right, the second push rod 192 drives the first push rod 191, the carrier frame 13 and the third push rod 193 to slide to the right.

[0067] Since the support wheel assembly can lift and lower the carrier frame 13, in order to enable the side-push drive assembly 19 to be lifted and lowered together with the carrier frame 13 without affecting the extension and retraction of the side-push drive assembly 19, a vertical limiting rod can be provided at the right end of the fourth push rod 194, and a fixed seat is provided on the carrier plate 12. The vertical limiting rod can be slidably inserted into the fixed seat. In this way, the side-push drive assembly 19 can slide up and down along the vertical limiting rod relative to the carrier plate 12. When the side-push drive assembly 19 is extended or retracted, the vertical limiting rod and the fixed seat can still limit the horizontal movement of the fourth push rod 194. In this way, when the functions of lifting and pushing out the battery pack are integrated, the structural design is more reasonable, thereby improving the reliability of the device.

[0068] It should be noted that the above-mentioned first linear module, second linear module, third linear module 1721 and fourth linear module may include but are not limited to one of the following: a screw linear module, a slide linear module, a synchronous belt linear module, a linear motor module, etc.

[0069] Furthermore, if Figure 2 As shown, the lower part of the upper loading support plate 11 can be connected to a floating frame 182 through a suspension chain 181. The floating frame 182 is rotatably connected to the lower loading mechanism 2. By providing the floating frame 182, the upper loading mechanism 1 can float within a certain range, which is convenient for fine adjustment.

[0070] Lastly, please refer to Figure 8 , Figure 8 FIG. 1 is a schematic diagram of the structure of an embodiment of the lower loading mechanism of the utility model. Figure 8 As shown, the lower mounting mechanism 2 includes a scissor fork lifting assembly 22, an upper frame 21, a lower frame 23, and a travel wheel assembly 24 for making the device travel on the track 3.
