[0065] like Figure 1 As shown in the figure, this embodiment provides a battery swapping device for new energy vehicles, including: a lifting mechanism 1, a battery swapping mechanism 2, and an unlocking mechanism 3.

[0066] The lifting mechanism 1 is used to secure the car and lift it to a preset height.

[0067] The battery swapping mechanism 2 includes a mobile base 21, a first platform 22, a second platform 23, and a third platform 24. The mobile base 21, the first platform 22, the second platform 23, and the third platform 24 are arranged vertically from bottom to top.

[0068] The movable base 21 is movably mounted under the car.

[0069] The first platform 22 is vertically mounted on the movable base 21. The second platform 23 is movably mounted on the first platform 22 along the length of the vehicle. The third platform 24 includes a left platform unit 241 and a right platform unit 242 symmetrically arranged. At least one of the left platform unit 241 and the right platform unit 242 is movably mounted on the second platform 23 to adjust the distance between the left platform unit 241 and the right platform unit 242.

[0070] There are multiple unlocking mechanisms 3. Some of the unlocking mechanisms 3 are located on the left platform unit 241 along the length direction, and the rest of the unlocking mechanisms 3 are located on the right platform unit 242 along the length direction.

[0071] The unlocking mechanism 3 can move along the length direction to align with the vehicle's locking mechanism and to remove and install the battery pack.

[0072] The battery pack of the new energy vehicle is usually installed at the bottom of the vehicle and is locked on the vehicle by a locking member.

The second platform 23 is used to adjust the position of the central axis of the third platform 24 in the length direction of the vehicle, so that the third platform 24 can be centered with the vehicle chassis, and the subsequent fine adjustment of the unlocking mechanism 3 is facilitated. The third platform 24 can adjust the distance between the left platform unit 241 and the right platform unit 242, so as to adjust the distance between the plurality of unlocking mechanisms 3 of the left platform unit 241 and the plurality of unlocking mechanisms 3 of the right platform unit 242, so that the plurality of unlocking mechanisms 3 are adapted to the positions of the plurality of locking members in the width direction of the vehicle. The unlocking mechanism 3 can also move in the length direction to adjust the distance between the two adjacent unlocking mechanisms 3 in the length direction, so as to adapt to the positions of the plurality of locking members in the length direction of the vehicle, so as to finally align the positions of the plurality of unlocking mechanisms 3 and the plurality of locking members in the bottom of the vehicle, thereby facilitating the unlocking and locking of the plurality of locking members.

[0076] Specifically, the lower side of the moving base 21 is provided with moving wheels and auxiliary wheels, the auxiliary wheels are used to bear the weight of the battery replacement mechanism 2, and the moving wheels provide the moving power for the moving base 21. Optionally, the moving wheels can be driven by a motor.

[0077] In an alternative embodiment, only one of the left platform unit 241 and the right platform unit 242 can move in the width direction. In another alternative embodiment, both of the left platform unit 241 and the right platform unit 242 can move in the width direction, and the distance is adjusted by the mutual approach and separation of the left platform unit 241 and the right platform unit 242.

[0078] The new energy automobile battery replacing device provided by the utility model can lift the automobile to be replaced to a proper height through the lifting mechanism 1, set the mobile base 21, the first platform 22, the second platform 23 and the third platform 24 on the battery replacing mechanism 2, and adjust the position of the unlocking mechanism 3 on the third platform 24 along the length direction, so that the plurality of unlocking mechanisms 3 can be aligned with the plurality of locking members on the automobile bottom, the battery pack can be disassembled or installed, the position of the unlocking mechanism 3 can be adjusted for different wheelbase and different position of the locking members of different new energy automobiles, different types of new energy automobiles can be adapted, and the universality of the battery replacing device is improved.

[0079] As shown in Figure 1 and Figure 3 The new energy automobile battery replacing device further comprises a first adjusting frame 4, a second adjusting frame 5, an adjusting gear 6 and a first driving assembly 7.

[0080] The first adjusting frame 4 is installed on the left platform unit 241, the second adjusting frame 5 is installed on the right platform unit 242, the first rack 42 of the first adjusting frame 4 and the second rack 52 of the second adjusting frame 5 are arranged in parallel and opposite, and the adjusting gear 6 is clamped between the first rack 42 and the second rack 52 and is arranged in mesh with the first rack 42 and the second rack 52 respectively.

[0081] The first driving assembly 7 is installed on the first platform 22 and is in transmission connection with the adjusting gear 6.

[0082] The left platform unit 241 and the right platform unit 242 are arranged in interval, and the interval between the left platform unit 241 and the right platform unit 242 is adjusted by the adjusting gear 6. The first adjusting frame 4 comprises a first mounting portion 41 and a first rack 42, the second adjusting frame 5 comprises a second mounting portion 51 and a second rack 52, the first mounting portion 41 and the first rack 42 are arranged vertically, the second mounting portion 51 and the second rack 52 are arranged vertically, the first mounting portion 41 is fixedly connected with the left platform unit 241, and the second mounting portion 51 is fixedly connected with the right platform unit 242.

[0083] The adjusting gear 6 rotates under the driving of the first driving assembly 7. When the adjusting gear 6 rotates towards one direction, the first rack 42 and the second rack 52 move in opposite directions along the width direction, the first rack 42 and the second rack 52 move away from each other, the left platform unit 241 and the right platform unit 242 move away from each other, and the distance between the left platform unit 241 and the right platform unit 242 is increased. When the adjusting gear 6 rotates towards another direction, the first rack 42 and the second rack 52 move in the same direction along the width direction, the first rack 42 and the second rack 52 move close to each other, the left platform unit 241 and the right platform unit 242 move close to each other, and the distance between the left platform unit 241 and the right platform unit 242 is decreased.

[0084] As shown in Figure 4 The first driving assembly 7 of the embodiment comprises a first rotary driving member 71, a transmission shaft 72 and a gear set 73.

[0085] The first rotary driving member 71 is installed on the first platform 22, and the output end of the first rotary driving member 71 is in transmission connection with the first end of the transmission shaft 72.

[0086] The second end of the transmission shaft 72 is connected with the input end of the gear set 73, and the output end of the gear set 73 is in transmission connection with the adjusting gear 6.

[0087] The driving force of the first rotary driving member 71 of the embodiment is transmitted to the adjusting gear 6 through the transmission shaft 72 and the gear set 73, so as to realize the driving of the adjusting gear 6 in different directions and the adjustment of the rotating speed. The adjustment of the rotating direction of the first rotary driving member 71 can adjust the distance between the left platform unit 241 and the right platform unit 242, and the adjustment of the rotating speed of the first rotary driving member 71 can adjust the speed of the left platform unit 241 and the right platform unit 242 moving close to or away from each other.

[0088] In one embodiment, the first rotary driving member 71 is set as a motor. The gear set 73 has two bevel gears arranged vertically, and the two bevel gears are in meshing to realize the change of the transmission direction by 90°. The transmission shaft 72 is set as a telescopic spline shaft. Since the second platform 23 can move along the length direction relative to the first platform 22, a strip-shaped hole is formed on the first platform 22, and the gear set 73 is installed on one end of the telescopic spline shaft. When the second platform 23 moves relative to the first platform 22, the telescopic spline shaft adjusts the length through the telescopic adjustment, so as to realize the adjustment of the position of the gear set 73.

[0089] Optionally, the third platform 24 is provided with a first position sensor 245 for detecting the position of the third platform 24 relative to the second platform 23, so as to ensure that the third platform 24 is moved to the position.

[0090] As shown in Figure 3The new energy vehicle battery replacing device of the embodiment further includes a support seat 8.

[0091] The support seat 8 is fixed to the second platform 23, and the third platform 24 is provided with a strip-shaped gap 243, and the support seat 8 is movably arranged relative to the strip-shaped gap 243.

[0092] When the battery pack is disassembled or assembled, the support seat 8 is used to support the battery pack. Moreover, the strip-shaped gap 243 is arranged along the width direction, and since the support seat 8 can only move relative to the strip-shaped gap 243, the support seat 8 plays a guiding role for the movement of the third platform 24 relative to the second platform 23, and the left platform unit 241 and the right platform unit 242 can only be adjusted relative to the second platform 23 along the width direction, thereby ensuring the stability of the movement of the left platform unit 241 and the right platform unit 242.

[0093] As shown in the drawings, Figure 3 The third platform 24 of the embodiment is provided with a limiting hole 244.

[0094] The limiting hole 244 extends along the width direction, and the second platform 23 is provided with a limiting column 231 movably arranged in the limiting hole 244.

[0095] Since the limiting hole 244 is arranged along the width direction, the limiting column 231 can only move relative to the limiting hole 244 along the width direction, thereby ensuring that the adjustment direction of the third platform 24 relative to the second platform 23 is along the width direction. Further, due to the limitation of the length of the limiting hole 244, the limiting column 231 can only move within the length range of the limiting hole 244, thereby limiting the adjustment range of the left platform unit 241 and the right platform unit 242 relative to the second platform 23, avoiding the third platform 24 from being detached from the second platform 23, and ensuring the reliability of the adjustment of the third platform 24 relative to the second platform 23.

[0096] As shown in the drawings, Figure 4 The new energy vehicle battery replacing device of the embodiment further includes a second driving assembly 9 and a screw rod 10.

[0097] The second driving assembly 9 is mounted to the first platform 22 and in transmission connection with the screw rod 10.

[0098] The screw rod 10 is rotatably mounted to the lower side of the first platform 22, and the lower side of the second platform 23 is provided with a threaded surface. The region of the first platform 22 where the screw rod 10 is arranged is provided with a through groove.

[0099] The screw rod 10 extends into the through groove and is arranged in meshing with the threaded surface.

[0100] The screw rod 10 is engaged with the screw surface, so that the screw rod 10 can drive the second platform 23 to move along the length direction relative to the first platform 22 during rotation of the screw rod 10, thereby realizing adjustment of the second platform 23 along the length direction.

[0101] Specifically, the second driving assembly 9 comprises a second rotating driving member and a transmission gear set, the input end of the transmission gear set is connected with the second rotating driving member, and the output end of the transmission gear set is connected with the screw rod 10.

[0102] In an optional embodiment, two second driving assemblies 9 and two screw rods 10 are provided, the two screw rods 10 are arranged on the left and right sides of the second platform 23 respectively, and the two screw rods 10 synchronously drive the second platform 23 to move along the length direction, so as to better adjust the position of the second platform 23.

[0103] As shown in Figure 5 The unlocking mechanism 3 of the embodiment comprises a guide rail 31, a sliding seat 32, a third rotating driving member 33, an unlocking shaft 34, an unlocking sleeve 35, a first elastic member 36 and an adjusting assembly 37.

[0104] The guide rail 31 is fixedly installed on the third platform 24, the sliding seat 32 is slidingly installed on the third platform 24, the unlocking shaft 34 is arranged through the guide rail 31 and rotatably arranged in the sliding seat 32, the third rotating driving member 33 is installed on the sliding seat 32 and in transmission connection with the unlocking shaft 34.

[0105] The unlocking sleeve 35 is sleeved on the top end of the unlocking shaft 34, the first elastic member 36 is clamped between the unlocking shaft 34 and the unlocking sleeve 35, the middle part of the unlocking shaft 34 has an external thread, the sleeve has an internal thread, and the external thread is engaged with the internal thread under the condition that the first elastic member 36 is compressed.

[0106] The adjusting assembly 37 is arranged on the third platform 24, and the adjusting assembly 37 is used for adjusting the position of the unlocking shaft 34 relative to the guide rail 31.

[0107] The edge of the guide rail 31 is fixedly installed on the side edge of the third platform 24, and the center of the guide rail 31 is provided with an opening for the unlocking shaft 34 to pass through.

[0108] Since the first elastic member 36 is clamped between the unlocking sleeve 35 and the unlocking shaft 34, the inner thread of the unlocking sleeve 35 and the outer thread of the unlocking shaft 34 cannot be engaged, and the unlocking sleeve 35 and the unlocking shaft 34 are not in transmission connection when the unlocking sleeve 35 is not subjected to force. With the first platform 22 being lifted, the top of the unlocking sleeve 35 abuts against the battery pack and bears extrusion force, the first elastic member 36 is compressed, the unlocking sleeve 35 moves downward, the inner thread of the unlocking sleeve 35 descends to the outer thread at the middle part of the unlocking shaft 34, the inner thread and the outer thread are engaged, and the unlocking shaft 34 drives the unlocking sleeve 35 to rotate synchronously. At this time, the unlocking sleeve 35 performs unlocking operation on the locking member of the battery pack through rotation to disassemble the battery pack.

[0109] Specifically, the third rotary driving member 33 can be a motor, and the first elastic member 36 and the second elastic member 374 can be springs.

[0110] Before the screwing operation on the battery pack, the spacing between the adjacent unlocking shafts 34 needs to be adjusted so that each unlocking shaft 34 can be aligned with the locking member on the battery pack. The adjusting assembly 37 of the embodiment can adjust the position of the sliding seat 32 so that the sliding seat 32 drives the unlocking shafts 34 to move synchronously.

[0111] Optionally, the unlocking mechanism 3 of the embodiment further comprises a second position sensor 38 arranged on the sliding seat 32 and opposite to the unlocking shaft 34, which can detect the position of the unlocking shaft 34 to ensure that the unlocking shaft 34 is aligned with the locking member, and can also detect the distance of the thread movement of the unlocking sleeve 35 to ensure whether the locking member is locked when the battery pack is installed.

[0112] As shown in Figure 5 The adjusting assembly 37 of the embodiment comprises a fixing frame 371, a third rack 372, a transmission gear 373, a second elastic member 374 and an electromagnet 375.

[0113] The fixing frame 371 is installed on the third platform 24, the third rack 372 is movably arranged on the fixing frame 371, and the transmission gear 373 is fixedly sleeved on the output end of the third rotary driving member 33.

[0114] The second elastic member 374 and the electromagnet 375 are clamped between the fixing frame 371 and the third rack 372. Under the electromagnetic action of the electromagnet 375, the third rack 372 moves along the fixing frame 371 towards the transmission gear 373, so that the third rack 372 and the transmission gear 373 are threadedly connected.

[0115] The third rack 372 moves along the direction close to and away from the third platform 24, and the third rotary drive 33 drives the transmission gear 373 to rotate. After the adjustment of the second platform 23 and the third platform 24 is completed, the position of the adjacent unlocking shaft 34 can be fine-tuned by adjusting the adjusting assembly 37.

[0116] When the electromagnet 375 is energized, because the electromagnet 375 has two repelling magnetic poles, the repelling force of the two magnetic poles pushes the third rack 372 close to the transmission gear 373 and engages with the transmission gear 373, the transmission gear 373 moves along the length direction of the third rack 372, and in turn drives the unlocking shaft 34 to move along the length direction, so as to realize the adjustment of the unlocking shaft 34 in the length direction. At the same time, the movement of the transmission gear 373 drives the second elastic member 374 to stretch, and the second elastic member 374 accumulates elastic force.

[0117] When the electromagnet is de-energized, the repelling force of the electromagnet 375 disappears, and under the action of the reset of the second elastic member 374, the second elastic member 374 drives the third rack 372 to reset, the third rack 372 is separated from the transmission gear 373, and the sliding seat 32 no longer moves along the third platform 24, and the position of the unlocking shaft 34 is fixed.
