[0071] The following specific embodiments will further illustrate the present disclosure in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0072] In order to enable a clearer understanding of the above-mentioned purposes, features and advantages of the present disclosure, the present disclosure will be described in detail below in conjunction with the drawings and specific embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict. In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present disclosure, and the described embodiments are only some of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making creative efforts, fall within the scope of protection of the present disclosure.

[0073] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present disclosure belongs. The terms used in the specification herein are only for the purpose of describing the specific embodiments and are not intended to limit the present disclosure.

[0074] In various embodiments, for the convenience of description and not limiting the present disclosure, the term "connected" used in the patent application specification and claims of the present disclosure is not limited to physical or mechanical connection, but can include electrical connection, whether direct or indirect. "Up", "down", "below", "left", "right", and the like are only used to represent relative positional relationships, which change accordingly when the absolute position of the described object changes.

[0075] The battery replacement rescue device is used for replacing the battery box of a vehicle. After the vehicle is stranded due to insufficient power, the battery replacement rescue vehicle can drive to the position of the vehicle to replace the battery box of the vehicle, so that the vehicle has sufficient power to continue driving immediately.

[0076] Figure 1 FIG. 1 is a structural schematic diagram of a battery replacement rescue device, Figure 2 FIG. 2 is a structural schematic diagram of the internal structure of the battery replacement rescue device. The battery replacement rescue device includes a moving mechanism, a battery compartment 40, a battery replacement trolley 50, and a lifting trolley 30. The moving mechanism is used to drive the battery compartment 40, the battery box 70, the battery replacement trolley 50, and the lifting trolley 30 as a whole to the position where the vehicle 80 is stranded, to replace the spare battery box 70 on the vehicle 80 through the lifting trolley 30 and the battery replacement trolley 50, to restore the driving ability of the vehicle 80, and to also transport the replaced battery box 70 with insufficient power or failure, thereby realizing a function of quickly and conveniently replacing the battery box 70 of the stranded vehicle 80.

[0077] Figure 3 FIG. 3 is a structural schematic diagram of a vehicle body 10, Figure 4 FIG. 4 is a structural schematic diagram of the vehicle body 10 in a lowered state. As shown in FIGS. 5 and 6, Figure 3 and Figure 4 The moving mechanism includes the vehicle body 10 and a vehicle compartment 20. The vehicle compartment 20 is used to accommodate other components of the battery replacement rescue device, and the vehicle body 10 can be an existing truck used to carry the vehicle compartment 20 to drive.

[0078] The vehicle compartment 20 is connected to the vehicle body 10 and is used to accommodate components such as the battery compartment 40 and the battery replacement trolley 50. The vehicle compartment 20 includes a compartment body and a tail door 21. The compartment body has a structure similar to a cargo box and has a large space inside. The bottom of the tail door 21 is rotatably connected to the compartment body. In this embodiment, the bottom of the tail door 21 is rotatably connected to the compartment body, and the tail door 21 can also be driven to rotate by a driving mechanism. In the open state, the tail door 21 is connected to the ground to allow the battery replacement trolley 50 and the lifting trolley 30 to enter or exit the compartment body. In the closed state, the tail door 21 closes the compartment body to facilitate transportation.

[0079] In order to facilitate the movement of the battery replacement trolley 50 and the lifting trolley 30, the vehicle body 10 adopts a lifting structure. In the normal driving state, the vehicle body 10 has a relatively high height. After reaching the destination, the vehicle body 10 can be lowered to reduce the height of the carrying compartment 20. Specifically, as shown in Figure 3 and Figure 4 The vehicle body 10 includes a carrying part 11, a rotating part 12, an extension component 14, front wheels 15 and rear wheels 16. The carrying part 11 is used to carry the battery compartment 40 and the battery replacement trolley 50. The carrying part 11 has a front end and a rear end, and the carrying compartment 20 can be arranged at the rear end position for carrying the carrying compartment 20 to move. The front wheels 15 are rotatably connected to the carrying part 11 and can be connected with the power component of the carrying part 11 to drive the entire vehicle body 10 to move as the driving wheel during driving. The rotating part 12 is rotatably connected to the middle part of the carrying part 11. Specifically, in this embodiment, the rotating part 12 is generally in the shape of a "door" character. The middle part of the length direction of the rotating part 12 is rotatably connected to the carrying part 11 through a rotating shaft 13. In this way, one end of the rotating part 12 is inclined upward in the direction of the front end of the carrying part 11, and the other end is inclined to extend in the direction of the rear end of the carrying part 11. The rear wheels 16 are rotatably connected to the end of the tail part of the rotating part 12 close to the carrying part 11. The extension component 14 is connected to the end of the carrying part 11 and the rotating part 12 relative to the rear wheels 16, and is used to drive the rotating part 12 to rotate relative to the carrying part 11, so that the front wheels 15 and the rear wheels 16 move relatively to adjust the height of the carrying part 11. In this embodiment, the extension component 14 can be a telescopic cylinder, or a hydraulic cylinder, or a gear and rack structure or a worm gear and screw structure driven by an electric motor. Those skilled in the art can select a suitable driving structure to realize the function of driving the rotating part 12 to rotate relative to the carrying part 11 around the rotating shaft 13.

[0080] In use, the extension component 14 is retracted to drive one end of the rotating part 12 to move in the upwardly inclined direction, so that the other end of the rotating part 12 moves in the direction close to the front wheels 15, the inclination of the rotating part 12 increases, and the front wheels 15 and the rear wheels 16 move close to each other, thereby increasing the height of the entire vehicle body 10. Correspondingly, the extension component 14 is extended to drive one end of the rotating part 12 to move in the downwardly inclined direction, so that the inclination of the rotating part 12 decreases and becomes more flat, and the front wheels 15 and the rear wheels 16 move away from each other, thereby reducing the height of the entire vehicle body 10. In this way, after reaching the destination of the rescue vehicle 80, the height of the entire vehicle body 10 can be reduced by the extension component 14, so as to facilitate the movement of the battery replacement trolley 50 and the lifting trolley 30 between the vehicle 80 and the carrying compartment 20.

[0081] Figure 5 is a structural schematic view of the battery replacement trolley 50. As Figure 5As shown, the battery replacement trolley 50 is used to carry the battery box 70 between the vehicle body 10 and the vehicle 80, and to interface the battery box 70 with the battery compartment 40 and the vehicle 80. Specifically, the bottom of the battery replacement trolley 50 is provided with a plurality of wheels 53, and the battery replacement trolley 50 can be moved from the vehicle compartment 20 to below the vehicle 80, or from below the vehicle 80 to the vehicle compartment 20. In addition, the battery replacement trolley 50 is also provided with a locking mechanism 51 and a guide column 52. The locking mechanism 51 is used to lock the battery box 70 on the battery replacement trolley 50 when the battery replacement trolley 50 approaches the vehicle 80 in the vertical direction, and can also unlock the battery box 70. The structure of the locking mechanism 51 can be existing, for example, it can be a screw rod and an unlocking motor, which drives the screw rod to screw into the nut located on the battery box 70 to achieve unlocking and locking operations. In addition, those skilled in the art can also achieve locking and unlocking of the battery box 70 according to other existing locking structures, which are not limited in the present application. The guide column 52 is generally a cone rod structure, which is connected to the battery replacement trolley 50 in the vertical direction, and is used to guide and position the battery box 70 to fall into or separate from the battery replacement trolley 50.

[0082] In some embodiments, the battery replacement trolley 50 itself has a lifting function and can independently complete the battery replacement operation. In the present embodiment, as an example, when the battery replacement trolley 50 does not have a lifting function, it needs to be completed in cooperation with the lifting trolley 30 to complete the battery replacement operation of the vehicle 80, which will be described together when the function of the lifting trolley 30 is described.

[0083] Figure 6 is the layout of the lifting mechanism 60 in the vehicle compartment 20. As shown in Figure 5 and Figure 6 The lifting mechanism 60 is arranged in the vehicle compartment 20 and is used to lift the battery replacement trolley 50. In order to more reasonably use the space in the vehicle compartment 20, in the present embodiment, the battery compartment 40 is arranged above the vehicle compartment 20 to leave space to store the lifting trolley 30. Therefore, on the one hand, the lifting mechanism 60 is needed to move the battery replacement trolley 50 to realize the interface of the battery box 70 between the battery replacement trolley 50 and the battery compartment 40, and on the other hand, the lifting mechanism 60 is also needed to adjust the height of the battery replacement trolley 50, so that the docking process of the battery box 70 can be implemented. However, those skilled in the art understand that the lifting mechanism 60 is not necessarily used. If the battery replacement trolley 50 itself has a lifting function, and the height of the battery compartment 40 is suitable for the battery replacement trolley 50, the battery replacement trolley 50 can also be directly docked with the battery compartment 40 to implement the interface operation of the battery box 70. In the present application, "interface" refers to the operation of transferring the battery box 70 between two devices, such as moving the battery box 70 from the battery replacement trolley 50 to the battery compartment 40, or moving the battery box 70 from the battery compartment 40 to the battery replacement trolley 50.

[0084] Figure 7 is a structural schematic diagram of the lifting mechanism 60. As shown in Figure 6 and Figure 7 , the lifting mechanism 60 includes a lifting platform 61 and a lifting driving assembly 62. The lifting platform 61 is generally in the form of a flat plate, and is movably connected to the vehicle body 10 in the vertical direction, for carrying the battery swap trolley 50. The lifting driving assembly 62 is connected to the inner wall of the vehicle compartment 20 and the lifting platform 61, for driving the lifting platform 61 to move the battery swap trolley 50 in the vertical direction. Specifically, the lifting driving assembly 62 can include a slide rail and slide block assembly to realize vertical movement, and can drive the lifting platform 61 to move up or down in the vertical direction by means of a pneumatic cylinder, a hydraulic cylinder, or a motor-driven ball screw structure, and the present application does not limit this. In use, when the battery swap trolley 50 moves to the lifting platform 61, the lifting platform 61 is driven by the lifting driving assembly 62 to carry the battery swap trolley 50 to a position corresponding to the battery compartment 40, and the battery swap trolley 50 and the battery compartment 40 complete the handover of the battery box 70, then the lifting platform 61 descends and the battery swap trolley 50 drives away from the lifting platform 61.

[0085] Figure 8 is a structural schematic diagram of the battery compartment 40 and the battery pack. As shown in Figure 8 , the battery compartment 40 is located on the vehicle body 10 and is used to store the battery box 70. In this embodiment, the battery compartment 40 includes a compartment body 41 and an extension rod 42. As an example, the compartment body 41 has one or more cavities for accommodating the battery box 70. The extension rod 42 is movably connected to the compartment body 41 in the horizontal direction and is located at the bottom wall of the cavity of the compartment body 41, and can be extended or retracted from the opening of the cavity to move the battery box 70.

[0086] When the battery changing trolley 50 is moved to the height corresponding to the storage body 41 by the lifting mechanism 60, the telescopic rod 42 is extended or retracted relative to the storage body 41 to exchange the battery box 70 with the battery changing trolley 50. Specifically, when the battery changing trolley 50 loaded with the battery box 70 is lifted to the height corresponding to the empty battery storage 40 (the bottom of the battery box 70 is slightly higher than the telescopic rod 42), the telescopic rod 42 in the empty battery storage 40 is extended to the lower side of the battery box 70, and then the lifting assembly 34 lowers the battery changing trolley 50 so that the battery box 70 is supported by the telescopic rod 42. Then, the lifting assembly 34 lowers the battery changing trolley 50 again until the battery box 70 is separated from the battery changing trolley 50; on the other hand, the telescopic rod 42 can retract the battery box 70 into the battery storage 40 to complete the operation of moving the battery box 70 from the battery changing trolley 50 to the battery storage 40; correspondingly, after the lifting assembly 34 moves the empty battery changing trolley 50 to the height of the battery storage 40 where the battery box 70 is stored, the telescopic rod 42 extends the battery box 70 towards the battery changing trolley 50 to move the battery box 70 from the battery storage 40 to the upper side of the battery changing trolley 50; then, the lifting assembly 34 lifts the battery changing trolley 50 to the height of the battery box 70, and after the telescopic rod 42 retracts into the battery storage 40, the lifting assembly 34 moves the battery changing trolley 50 to complete the operation of moving the battery box 70 from the battery storage 40 to the battery changing trolley 50.

[0087] Figure 9 is a structural diagram of the lifting trolley 30, Figure 10 is a structural diagram of the lifting trolley 30. As Figure 9 and Figure 10 shown, the lifting trolley 30 is used to lift the vehicle 80 to cooperate with the battery changing trolley 50 to complete the operation of exchanging the battery box 70 between the vehicle 80, such as moving the battery box 70 from the vehicle 80 to the battery changing trolley 50, or installing the battery box 70 loaded by the battery changing trolley 50 to the vehicle 80. Those skilled in the art understand that the lifting trolley 30 is not necessary, and in the case where the battery changing trolley 50 itself has a lifting function, the battery changing operation can also be completed without the cooperation of the lifting trolley 30.

[0088] In this embodiment, the lifting trolley 30 comprises a lifting trolley body 10 and a lifting assembly 34. The lifting trolley body 10 comprises two opposite side plates 31 and walking wheels 33 connected to the bottom of the side plates 31. The two side plates 31 are spaced apart to form a cavity 32 with a predetermined width between the two side plates 31, and the lifting trolley 30 can lift the vehicle 80 in the area of the cavity 32, and the battery replacement trolley 50 can perform the operation of exchanging the battery box 70 with the vehicle 80 in the cavity 32. The lifting assembly 34 is arranged on the inner side of the side plate 31 and is used to clamp the wheels 53 of the vehicle 80 and lift the vehicle 80. The lifting assembly 34 corresponds to the wheels 53 of the vehicle 80, and in this embodiment, the number of lifting assemblies 34 is four, two of which are arranged on the inner side of one side plate 31, and the other two are arranged on the inner side of the other side plate 31. In use, each lifting assembly 34 corresponds to one wheel 53 and is used to lift one wheel 53, and through the cooperation of multiple lifting assemblies 34, the lifting operation of the vehicle 80 is realized.

[0089] Figure 11 is a structural schematic view of the lifting assembly 34. As shown in Figure 11 , the lifting assembly 34 comprises a pair of clamping arms 341, a first connecting plate 348, a second connecting plate 347, and a clamping driving assembly. The first connecting plate 348 and the second connecting plate 347 are used to realize the position adjustment of the clamping arms 341, that is, to move in the up-down and left-right directions. Specifically, the first connecting plate 348 is connected to the inner side of the side plate 31 and moves in the vertical direction through a slider-rail structure, and similarly, the second connecting plate 347 can also move in the horizontal direction through a slider-rail structure and is connected to the first connecting plate 348, and a pair of clamping arms 341 are rotatably connected to the second connecting plate 347. In this way, by controlling the first connecting plate 348 to move in the vertical direction on the side plate 31, the clamping arms 341 are realized to move in the vertical direction, and by controlling the second connecting plate 347 to move in the horizontal direction on the first connecting plate 348, the clamping arms 341 are realized to move in the horizontal direction, so that the position of the pair of clamping arms 341 can be adjusted, so that the position of the clamping arms 341 corresponds to the position of the wheels 53, and after the clamping operation of the wheels 53 is completed, the first connecting plate 348 is used to perform the operation of lifting the vehicle 80.

[0090] Figure 12 is a structural schematic view of the clamping arms 341 in the open state. As shown in Figure 11 and 12 , the clamping driving assembly is used to drive the clamping arms 341 to move relatively close or away to clamp the wheels 53. Specifically, the clamping driving assembly comprises a clamping motor 346, a screw rod 344, a moving block 343, and a connecting rod 342.

[0091] Specifically, the screw rod 344 is rotatably connected to the second connecting plate 347 through bearings or other components. In this embodiment, the screw rod 344 has multiple support points at both ends and at the middle position, and one end of the screw rod 344 is connected to the clamping motor 346 for rotation under the drive of the clamping motor 346. The moving blocks 343 correspond to the clamping arms 341 and are threadedly connected to the screw rod 344 for movement in the horizontal direction under the drive of the screw rod 344. In this embodiment, the moving blocks 343 have opposite screw directions, and are movably connected to the second connecting plate 347 through the slide rails 345, so that the two moving blocks 343 can move towards or away from each other under the drive of the screw rod 344 during rotation of the screw rod 344. The connecting rods 342 are connected between the moving blocks 343 and the clamping arms 341 for driving the clamping arms 341 to open or fold under the traction of the moving blocks 343. Specifically, one end of the connecting rod 342 is hingedly connected to the moving block 343, and the other end is hingedly connected to the clamping arm 341, and the hinged positions are offset from the rotation positions of the clamping arms 341, for driving the clamping arms 341 to rotate relative to the second connecting plate 347 to open to clamp the tires of the vehicle 80 under the traction of the moving blocks 343. The ends of the clamping arms 341 are hingedly connected to the second connecting plate 347, and a pair of clamping arms 341 are oppositely arranged, and a plurality of rotatable rollers 349 are arranged on the opposite sides (inner sides) of the clamping arms 341, for reducing the friction with the wheels 53 when clamping the wheels 53, protecting the wheels 53 and reducing the effect of wearing the wheels 53.

[0092] Figure 13 is a structural schematic view of the clamping arms 341 in the folded state. In combination with Figure 11 and 12 , as Figure 13 shown, when it is necessary to open the clamping arms 341, the clamping motor 346 rotates to drive the pair of moving blocks 343 to move towards each other through the screw rod 344, and the moving blocks 343 drive the clamping arms 341 to swing towards each other through the connecting rods 342, until the clamping arms 341 clamp the wheels 53 from the front-to-rear direction of the wheels 53, and are in the position as Figure 12 shown. When it is necessary to fold the clamping arms 341, the screw rod 344 is reversely rotated under the drive of the clamping motor 346, and the moving blocks 343 move in the direction away from each other, and the clamping arms 341 are reversely swung, i.e. swing in the direction away from each other through the connecting rods 342, until the two clamping arms 341 are attached to the second connecting plate 347.

[0093] Figure 14 is a structural schematic view of the lifting trolley 30 lifting the vehicle 80. As Figure 14As shown, after the clamping arms 341 of the lifting assembly 34 of the vehicle 80 open to clamp the wheels 53, the first connecting plate 348 is pulled to move in the vertical direction to achieve the function of lifting the vehicle 80.

[0098] Step S40: the battery changing trolley 50 moves from the moving mechanism to the position of the vehicle 80 to obtain the battery box 70 from the vehicle 80. As shown in the figure, in this step, first, the lifting trolley 30 moves from the vehicle compartment 20 to the position of the vehicle 80. Then, the clamping arms 341 of the lifting trolley 30 move to the positions corresponding to the tires of the vehicle 80 and then move close to each other to clamp the tires of the vehicle 80. Then, the clamping arms 341 are raised to lift the vehicle 80 to a suitable height, and then the battery changing trolley 50 moves to the position below the vehicle 80 to obtain the battery box 70 of the vehicle 80. Figure 17

[0099] Step S50: the battery changing trolley 50 moves to the moving mechanism with the battery box 70, and exchanges the battery box 70 with the battery compartment 40 in the moving mechanism. As shown in the figure, in this step, the battery changing trolley 50 moves to the lifting platform 61 in the vehicle compartment 20 with the battery box 70 through the tail door 21; then, the lifting platform 61 lifts the battery changing trolley 50 to the position corresponding to the compartment body 41. Then, the battery changing trolley 50 exchanges the battery box 70 with the compartment body 41, and stores the loaded battery box 70 in the compartment body 41; then, the lifting mechanism 60 moves the battery changing trolley 50 to obtain a new battery box 70 from another compartment body 41. Figure 18

[0100] Step S60: the battery changing trolley 50 moves to the position of the vehicle 80 with the battery box 70, and moves the loaded battery box 70 to the vehicle 80.
