[0027] Next, the embodiments of the present application are described in detail.

[0028] like Figure 1 and Figure 2 As shown, the present application provides a battery replacement device, including a battery box 10, a sliding frame 20, a hanging assembly 30 and an installation assembly 40.

[0029] The battery box 10 is used to provide power to the vehicle. The sliding frame 20 is sleeved on the outside of the battery box 10 and can slide up and down relative to the battery box 10. The mounting assembly 40 is fixedly arranged on the vehicle and locks or unlocks the battery box 10 by cooperating with the sliding frame 20. The hanging assembly 30 can move relative to the mounting assembly 40 and can drive the battery box 10 to move up and down or horizontally to drive the battery box 10 to the correct installation position.

[0030] The upper and lower sides of the battery box 10 protrude outward to form an upper limit portion 11 and a lower limit portion 12 respectively. The sliding frame 20 is sleeved between the upper limit portion 11 and the lower limit portion 12 and can slide up and down between the upper limit portion 11 and the lower limit portion 12.

[0031] The bottom of the battery box 10 is provided with a plug 13 and a sealing cone 14 that cooperate with the mounting assembly 40. There is one plug 13, which is located in the middle of the bottom of the battery box 10. The plug 13 can be connected to the electric powertrain of the vehicle through the mounting assembly 40. There are two sealing cones 14, which are located on both sides of the plug 13. The sealing cone 14 is connected to the heat exchange pipeline inside the battery box 10, and can be connected to the thermal management device of the vehicle through the mounting assembly 40.

[0032] The sliding frame 20 includes a limit plate 21 and a crimping plate 22. The limit plate 21 is arranged horizontally and moves between the upper limit portion 11 and the lower limit portion 12. The crimping plate 22 is vertically connected to the limit plate 21 and is located below the limit plate 21. An oblique guide surface 221 is formed at the lower part of the inner wall of the crimping plate 22, and the guide surface 221 gradually tilts outward from top to bottom. A clamping groove 23 is provided on the outer side of the crimping plate 22, and the clamping groove 23 cooperates with the hoisting assembly 30 and moves in the horizontal or vertical direction driven by the hoisting assembly 30.

[0033] The hoisting assembly 30 includes a traverse device 31, a clamping frame 32, a dual-axis motor 33, a pair of reverse screws 34 and a pair of clamping rods 35. The traverse device 31 is a rigid structure with traverse lifting and lowering functions, such as lifting and lowering using a telescopic cylinder, for controlling the clamping rod 35 to move up and down or horizontally.

[0034] Specifically, the clamping frame 32 extends laterally and is connected to the lower part of the lateral movement device 31. A dual-axis motor 33 is mounted on the clamping frame 32, and two output ends of the dual-axis motor 33 are mounted with reverse screws 34, and the thread directions of the two reverse screws 34 are opposite. The clamping rod 35 is slidably mounted on the clamping frame 32. A pair of reverse screws 34 respectively engage and penetrate a pair of clamping rods 35, and are used to control the relative distance between the pair of clamping rods 35. The bottom of the clamping rod 35 is provided with a clamping portion 351 protruding inwardly, and the clamping portion 351 drives the movement of the sliding frame 20 by engaging with the clamping groove 23.

[0035] It is understandable that the lifting assembly 30 of the present application drives the battery box 10 not by directly connecting the lifting assembly 30 with the battery box 10, but indirectly by the lifting assembly 30 driving the sliding frame 20 to move, and the sliding frame 20 further driving the battery box 10 to move.

[0036] The mounting assembly 40 includes a mounting frame 41, a stopper rod 42, a strong magnet 43, a socket 44, a buffer rod 45, a circulation hose 46, and a tapered groove 47. The mounting frame 41 is fixedly mounted on the vehicle, and includes a bottom plate 411 and a support plate 412. The bottom plate 411 is arranged horizontally, and the support plate 412 is vertically connected to the bottom plate 411 and is located above the bottom plate 411. The support plate 412 protrudes inward to form a bearing block 413, and the battery box 10 can be placed on the bearing block 413 and locked in this position.

[0037] The limiting rod 42 is arranged horizontally, slidably inserted on the support plate 412, and can be slidably extended into or extended from the inside of the mounting frame 41. The portion of the limiting rod 42 located outside the support plate 412 is sleeved with a first elastic member 421. Specifically, in this embodiment, the limiting rod 42 and the first elastic member 421 are both a pair, which are respectively arranged on opposite sides of the mounting assembly 40, and the first elastic member 421 is a top spring. The strong magnet 43 is arranged on the top of the mounting frame 41, and the sliding frame 20 is made of iron material. When the strong magnet 43 and the sliding frame 20 are close to each other, they can attract each other.

[0038] The socket 44 is slidably mounted on the mounting frame 41 and connected to the electric powertrain of the vehicle. The socket 44 is plugged into the plug 13 to connect the plug 13 to the electric powertrain of the vehicle. The buffer rod 45 is a pair, the upper ends of which slide through the two sides of the socket 44 and the lower ends are vertically fixed to the bottom plate 411. The buffer rod 45 is provided with a second elastic member 451.

[0039] The setting of the second elastic member 451, on the one hand, provides a certain degree of buffer protection when the plug 13 is plugged into the socket 44, reduces the contact wear between the plug 13 and the socket 44, and extends the service life of the device; on the other hand, it provides a certain supporting force to the socket 44 when the plug 13 is inserted, making the connection between the plug 13 and the socket 44 more stable and reliable, and helping to prevent the plug 13 from accidentally falling off due to external vibrations.

[0040] The circulation hose 46 is slidably plugged into the bottom plate 411 and connected to the thermal management device of the vehicle. The conical groove 47 is fixed to the top of the circulation hose 46 and is squeezed and matched with the sealing cone 14. The arrangement of the circulation hose 46, the conical groove 47 and the sealing cone 14 connects the heat exchange pipeline in the battery box 10 and the thermal management device of the vehicle, which can achieve effective control and regulation of the temperature of the battery box 10. A third elastic member 461 is provided on the circulation hose 46, and the two ends of the third elastic member 461 abut against the conical groove 47 and the bottom plate 411 respectively. Specifically, the third elastic member 461 is a spring.

[0041] The setting of the third elastic member 461, on the one hand, provides a certain degree of buffer protection when the sealing cone 14 and the conical groove 47 are squeezed, reduces the contact wear between the sealing cone 14 and the conical groove 47, and extends the service life of the device; on the other hand, it provides a certain supporting force to the conical groove 47, making the connection between the sealing cone 14 and the conical groove 47 more stable and reliable, and helps prevent the sealing cone 14 from accidentally falling off due to external vibration.

[0042] Preferably, a valve is provided in the conical groove 47 to cooperate with the sealing cone 14. The valve opens when the sealing cone 14 and the conical groove 47 are squeezed against each other, and closes when the sealing cone 14 and the conical groove 47 are not squeezed against each other, further ensuring the reliability and safety of the heat exchange pipeline in the battery box 10 being connected to the thermal management device of the vehicle.

[0043] When installing the battery box 10, the lateral movement device 31 drives the battery box 10 to move to the top of the installation assembly 40, and then drives the clamping frame 32 to descend, so that the clamping rod 35 drives the sliding frame 20 to descend. Driven by the sliding frame 20, the battery box 10 descends to the locking position, the plug 13 is inserted into the socket 44, and the sealing cone 14 squeezes the conical groove 47. The battery box 10 is placed on the bearing block 413 and does not move down any further.

[0044] The sliding frame 20 continues to move downward, and when it moves to a certain position, the guide surface 221 contacts the outermost end of the limit rod 42 and abuts against the first elastic member 421. As the sliding frame 20 continues to move downward, the guide surface 221 overcomes the pressure of the first elastic member 421 and gradually pushes the limit rod 42 into the support plate 412. When the sliding frame 20 moves to the bottom, the inner wall of the crimping plate 22 abuts against the limit rod 42, and the limit rod 42 extends into the mounting frame 41 and is located above the lower limit portion 12, thereby locking the battery box 10. At this time, the flat portion of the inner wall of the crimping plate 22 contacts the limit rod 42 and restricts the limit rod 42 from slipping outward.

[0045] Furthermore, in order to ensure that the limiting rod 42 can be fully inserted into place, the height of the guide surface 221 in the vertical direction is not less than the height of the lower limiting portion 12. In order to ensure that the limiting rod 42 can be inserted above the lower limiting portion 12, the height difference between the limiting rod 42 and the bearing block 413 is not less than the height of the lower limiting portion 12.

[0046] When the sliding frame 20 moves to the bottom, the strong magnet 43 fits the bottom surface of the limit plate 21, and the strong magnet 43 and the sliding frame 20 are attracted to prevent the sliding frame 20 from moving upward. The dual-axis motor 33 drives the reverse screw 34 to rotate, so that the pair of clamping rods 35 move away from each other, and the clamping portion 351 is separated from the clamping groove 23. The traverse device 31 drives the clamping frame 32 to move upward to achieve the installation of the battery box 10. At this time, the battery box 10 and the sliding frame 20 are both installed on the installation assembly 40.

[0047] When the battery box 10 needs to be removed, the transverse movement device 31 drives the clamping frame 32 to descend until the clamping portion 351 is located on both sides of the clamping groove 23 in the horizontal direction. The dual-axis motor 33 drives the reverse screw 34 to rotate, so that a pair of clamping rods 35 approach each other and engage with the clamping groove 23. The transverse movement device 31 drives the clamping frame 32 to rise, and the clamping rod 35 drives the sliding frame 20 to rise. The sliding frame 20 disengages from the limit rod 42, and the limit rod 42 slides outward under the action of the first elastic member 421, and no longer contacts the lower limit portion 12, thereby unlocking the battery box 10. The sliding frame 20 continues to move upward until it contacts the upper limit portion 11, and drives the battery box 10 to move upward. The plug 13 disengages from the socket 44, and the sealing cone 14 disengages from the conical groove 47, thereby realizing the removal of the battery box 10.

[0048] like Figure 3 As shown, the present application also provides a vehicle, comprising the battery replacement device as described above.

[0049] The vehicle of this embodiment is a new energy commercial vehicle, and the installation component 40 is arranged at the front of the cargo box, and the battery box 10 is also located at the front of the cargo box after assembly. In actual application, the positions of the installation component 40 and the battery box 10 can be flexibly set according to different vehicle models. It can be understood that after the battery box 10 is installed, the part of the battery replacement device connected to the vehicle body includes the battery box 10, the sliding frame 20 and the installation component 40, and the lifting component 30 does not have a fixed relationship with the vehicle, so multiple vehicles can share the lifting component 30.

[0050] The battery replacement device and vehicle of the present application drive the movement of the battery box 10 by setting up a lifting assembly 30, and realize the locking or unlocking of the battery box 10 through the cooperation between the sliding frame 20 and the installation assembly 40, so that the battery box 10 can be disassembled, assembled and replaced, and no additional power is required to lock and unlock the position of the battery box 10 during the replacement process, which simplifies the operation process of replacing the battery box 10, improves the flexibility and convenience of the battery replacement process, and improves the replacement efficiency.

[0051] The above is only a preferred implementation mode of the present application, and does not constitute any form of limitation to the present application. Although the present application has been disclosed as a preferred implementation mode as above, it is not used to limit the present application. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent implementation modes without departing from the scope of the technical solution of the present application. However, any simple modification, equivalent change and modification made to the above implementation modes based on the technical essence of the present application without departing from the content of the technical solution of the present application still fall within the scope of the technical solution of the present application.
