[0032] In response to the above problems, an embodiment of the present application provides a battery replacement vehicle that can reduce the space occupied by the battery replacement vehicle.

[0033] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0034] Figure 1 is a schematic diagram of a battery replacement vehicle and a battery compartment shown in an embodiment of the present application; Figure 2 It is a schematic diagram of the structure of the battery replacement vehicle shown in an embodiment of the present application.

[0035] See also Figure 1-Figure 2 The battery replacement vehicle includes a main body 1, a fixed frame 2, a mobile frame 3 and a mobile device 4. The main body 1 can travel on the ground, the fixed frame 2 can be connected to the battery compartment 6 of the robot, so that the fixed frame 2 can carry the battery 5 taken out from the battery compartment 6, and the mobile device 4 can move the mobile frame 3 to the position as shown in the figure. Figure 7 The mobile frame 3 is in the position shown, docked with the battery compartment 6 , so that the mobile frame 3 can carry the battery 5 taken out from the battery compartment 6 , and the mobile device 4 can also move the mobile frame 3 to the top of the fixed frame 2 .

[0036] See also Figure 1-2 The bottom of the main body 1 is provided with wheels to facilitate the staff to push the main body 1 to move. Preferably, the wheels are universal wheels. The fixing frame 2 is fixed to the main body 1. The fixing frame 2 can be used to place batteries 5 to be charged taken out from the battery compartment 6, or batteries 5 that have been charged and are ready to be installed in the battery compartment 6. The height of the fixing frame 2 can be lower than or equal to the height of the battery compartment 6. When the fixing frame 2 is aligned with the battery compartment 6, the staff can push the batteries 5 on the fixing frame 2 into the battery compartment 6, or drag the batteries 5 in the battery compartment 6 to the empty fixing frame 2. The mobile frame 3 can also be used to place batteries 5 to be charged taken out from the battery compartment 6, or batteries 5 that have been charged and are ready to be installed in the battery compartment 6.

[0037] See also Figure 1-Figure 2The mobile frame 3 is installed on the mobile device 4. The mobile frame 3 is located above the fixed frame 2. The mobile frame 3 overlaps with the fixed frame 2 in the vertical direction. During the replacement of the battery 5, the mobile frame 3 can move horizontally at a first height above the fixed frame 2. The mobile frame 3 can also perform lifting and lowering movements between the first height and the second height where the fixed frame 2 is located. The mobile device 4 can provide power for the movement of the mobile frame 3. The mobile device 4 is installed on the main body 1. The mobile device 4 is connected to the mobile frame 3. The mobile device 4 is used to drive the mobile frame 3 to move horizontally and lift and lower, so that the mobile frame 3 moves between the top of the fixed frame 2 and the horizontal side of the fixed frame 2. When the battery replacement vehicle moves, or when there is no need to replace the battery 5 for the robot, the mobile device 4 can drive the mobile frame 3 to move above the fixed frame 2. At this time, only the main body 1 and the fixed frame 2 occupy the ground space, and the mobile frame 3 will not affect the ground space of the battery replacement vehicle, thereby saving the ground space of the battery replacement vehicle. When it is necessary to transfer the battery 5 in the battery compartment 6 to the mobile frame 3 or place the battery 5 on the mobile frame 3 into the battery compartment 6, the mobile device 4 can drive the mobile frame 3 from above the fixed frame 2 to the horizontal side of the fixed frame 2, so that the mobile frame 3 and the fixed frame 2 are at the same height. At this time, the mobile frame 3 can be aligned with the battery compartment 6, and the staff transfers the battery 5 between the mobile frame 3 and the battery compartment 6. The movement of the mobile frame 3 is controlled by the mobile device 4, so that the mobile frame 3 can move horizontally at a first height above the fixed frame 2, and perform lifting and lowering movements between the first height and the second height. When the battery replacement vehicle is moving, or when there is no need to replace the battery 5 for the robot, the mobile frame 3 can be moved above the fixed frame 2, so that the mobile frame 3 and the fixed frame 2 occupy the same space. At this time, only the main body 1 and the fixed frame 2 occupy the ground space, thereby saving the overall space occupied by the battery replacement vehicle, making it convenient for the battery replacement vehicle to pass through narrow passages, and during the battery replacement process, the fixed frame and the mobile frame of the battery replacement vehicle are arranged front and back, allowing the battery replacement vehicle to perform battery replacement operations in narrow passages, thereby improving the efficiency of battery replacement.

[0038] See also Figure 2In some embodiments, the mobile device 4 includes a lifting mechanism 41 and a translation mechanism 42. The lifting mechanism 41 is installed on the main body 1, and the lifting mechanism 41 is connected to the translation mechanism 42. The mobile frame 3 is installed on the translation mechanism 42. The mobile frame 3 moves horizontally at a first height above the fixed frame 2 through the translation mechanism 42. The lifting mechanism 41 drives the translation mechanism 42 to rise and fall between the first height and the second height where the fixed frame 2 is located, and then the mobile frame 3 rises and falls between the first height and the second height as the translation mechanism 42 moves. When it is necessary to move the mobile frame 3 from directly above the fixed frame 2 to the horizontal side of the fixed frame 2, the mobile frame 3 is first translated from directly above the fixed frame 2 to the obliquely above the fixed frame 2 by the translation mechanism 42, so that the mobile frame 3 and the fixed frame 2 are staggered up and down, and the translation mechanism forms an avoidance groove, and the vertical projection of the mobile frame 3 does not overlap with the fixed frame 2. Then the lifting mechanism 41 controls the mobile frame 3 to descend, so that the height of the mobile frame 3 is the same as the second height of the fixed frame 2 and is on the horizontal side of the fixed frame 2. At this time, the fixed frame 2 is located in the above-mentioned avoidance groove formed by the translation mechanism; when it is necessary to move the mobile frame 3 from the horizontal side of the fixed frame 2 to directly above the fixed frame 2, the lifting mechanism 41 first lifts the mobile frame 3, so that the mobile frame 3 is higher than the top of the fixed frame 2 and is located at the first height, and then the mobile frame 3 is moved to directly above the fixed frame 2 by the translation mechanism 42. The mobile frame 3 moves back and forth between the top of the fixed frame 2 and the horizontal side of the fixed frame 2 by horizontal and vertical movement, which can reduce the space used by the battery replacement vehicle, make the overall structure of the battery replacement vehicle more compact, and facilitate the miniaturization of the battery replacement vehicle.

[0039] Figure 3 is a schematic structural diagram of a fixing frame 2 shown in an embodiment of the present application;

[0040] See also Figure 2-Figure 3The lifting mechanism 41 includes a hydraulic cylinder 411, a roller 412 and a chain 413. The cylinder barrel of the hydraulic cylinder 411 is fixed on the main body 1. The bottom end of the piston rod of the hydraulic cylinder 411 is installed in the cylinder barrel of the hydraulic cylinder 411. The piston rod of the hydraulic cylinder 411 is retracted in the vertical direction. The staff can control the lifting of the piston rod by stepping on the lifting handle of the hydraulic cylinder 411. The piston rod of the hydraulic cylinder 411 is connected to the roller 412. By controlling the lifting of the piston rod, the roller 412 is lifted and lowered. The middle part of the chain 413 is hung on the roller 412. The chain 4 One end of the chain 413 is fixed to the main body 1, and the other end of the chain 413 is fixed to the translation mechanism 42. When the piston rod rises, the roller 412 rises, and the roller 412 drives the first end of the chain 413 upward, and the first end is one end connected to the translation mechanism 42, so that the chain 413 drives the translation mechanism 42 to rise. On the contrary, when the piston rod needs to be lowered, the staff can open the valve of the hydraulic cylinder 411, and the piston rod descends under the action of gravity, and the translation mechanism 42 also descends accordingly, thereby realizing the lifting and lowering control of the translation mechanism 42 by the lifting mechanism 41. Among them, the hydraulic cylinder 411 can be electrically controlled or manually inflated. In this embodiment, the lifting mechanism 41 also includes an armrest, and the staff can inflate the hydraulic cylinder 411 by pressing the armrest. In addition, the lifting mechanism 41 can be a screw slide module, and the slide is connected to the translation mechanism 42, and the translation mechanism 42 is driven to rise and fall by rotating the screw.

[0041] Figure 4 It is a schematic diagram of the structure of the mobile rack 3 shown in the embodiment of the present application.

[0042] See also Figure 2-Figure 4In order to ensure that when the lifting mechanism 41 controls the translation mechanism 42 to lift and lower, the translation mechanism 42 can be lifted and lowered in a straight line, the main body 1 is provided with a vertically extending guide rod 11, and the fixed frame 2 is installed at the bottom end of the guide rod 11. The translation mechanism 42 is provided with a first guide wheel 423, a second guide wheel 424 and a limit rod 425. The guide rod 11 is clamped between the first guide wheel 423 and the second guide wheel 424. The first guide wheel 423 is located above the second guide wheel 424. When the staff operates the battery replacement vehicle to replace the battery 5, the battery compartment 6 is located in front of the battery replacement vehicle, and the staff is located behind the battery replacement vehicle. The first guide wheel 423 limits the movement of the movable frame 3 forward, and the second guide wheel 424 limits the movement of the movable frame 3 backward, so that when the lifting mechanism 41 drives the movable frame 3 to lift and lower, the movable frame 3 will not move forward or backward. In order to ensure that the moving frame 3 does not deflect during the lifting process, the limiting rod 425 is arranged between the first guide wheel 423 and the second guide wheel 424, and the limiting rod 425 abuts against one side of the guide rod 11, so that the moving frame 3 can only move up and down. The first guide wheel 423 and the second guide wheel 424 can rotate relative to the limiting rod 425. In addition to limiting the forward and backward movement of the moving frame 3, the first guide wheel 423 and the second guide wheel 424 can also make the moving frame 3 smoother during the lifting process, avoiding the phenomenon of jamming due to friction during the lifting process of the moving frame 3.

[0043] See also Figure 2-Figure 4 In this embodiment, the translation mechanism 42 includes a mounting frame 421 and a telescopic mechanism 422. The mounting frame 421 is connected to the lifting mechanism 41. The mounting frame 421 is frame-shaped. The vertical projection of the mounting frame 421 does not overlap with the fixed frame 2. The mobile frame 3 is installed on the telescopic mechanism 422. When the telescopic mechanism 422 drives the mobile frame 3 to extend horizontally, an avoidance groove is formed between the mobile frame 3 and the mounting frame 421, and the fixed frame 2 and the mobile frame 3 are staggered in the vertical direction. The lifting mechanism 41 can drive the mounting frame 421 to drop to the second height of the fixed frame 2. At this time, the fixed frame 2 is located in the avoidance groove of the mounting frame 421, and the mobile frame 3 is on the horizontal side of the fixed frame 2. Such a design can reduce the space occupied by the mounting frame 421, which is convenient for the battery replacement vehicle to work in a narrow space. Specifically, when it is necessary to push the mobile frame 3 to move along the telescopic mechanism 422, it can be achieved by the staff pushing the mobile frame 3, or the mobile frame 3 can be driven by the motor to translate. In some embodiments, the telescopic mechanism 422 is a slide rail, and the telescopic mechanism 422 is installed on the inner side of the mounting frame 421. In some embodiments, the telescopic mechanism 422 can be a pneumatic telescopic rod or a screw slide module.

[0044] See also Figure 1-Figure 4, the mobile rack 3 and the fixed rack 2 both include a placement table, a smooth bar and a buffer pad, the smooth bar is located on the upper surface of the placement table, the smooth bar extends in the horizontal direction, the buffer pad is installed on the side of the placement table, and the buffer pad is located in the output direction of the smooth bar. The placement table of the mobile rack 3 is the first placement table 31, and the placement table of the fixed rack 2 is the second placement table 21; the smooth bar of the mobile rack 3 is the first smooth bar 32, and the smooth bar of the fixed rack 2 is the second smooth bar 22; the buffer pad of the mobile rack 3 is the first buffer pad 34, and the buffer pad of the fixed rack 2 is the second buffer pad 24. In some embodiments, the smooth bar can be replaced by a plastic plate such as polytetrafluoroethylene with a small friction coefficient, so that the battery can slide on the placement table.

[0045] See also Figure 1-Figure 4 The mobile frame 3 includes a first buckle 33, which is connected to the first placement platform 31 and is used to fix the battery 5 located on the mobile frame 3. Specifically, the first buckle 33 is fixed to the upper surface of the first placement platform 31, and the first buckle 33 is hook-shaped. Since the battery 5 used by the robot has a rotatable handle, in order to prevent the battery 5 from falling off the mobile frame 3 when the mobile frame 3 transports the battery 5, the handle can be buckled on the first buckle 33, so that the battery 5 is relatively fixed to the first placement platform 31 to ensure the safety of the battery 5. The first smooth bar 32 is located on the upper surface of the first placement platform 31, and the first smooth bar 32 extends in the horizontal direction. The battery 5 can be placed on the first smooth bar 32. When the first placement platform 31 is aligned with the battery compartment 6, the staff can flip the handle to disengage the buckle of the first buckle 33, and then push the battery 5 into the battery compartment 6 along the first smooth bar 32. The first smooth bar 32 allows the staff to push the battery 5 into the battery compartment 6 more smoothly. The first buffer pad 34 is installed on the side of the first placement table 31, and the first buffer pad 34 is located in the output direction of the first flow strip 32. When the mobile frame 3 is aligned with the battery compartment 6, the mobile frame 3 needs to be close to the battery compartment 6. In order to avoid collision between the mobile frame 3 and the robot, the side of the first placement table 31 with the first buffer pad 34 can be moved toward the battery compartment 6. Even if the robot comes into contact with the mobile frame 3, the robot will first contact the first buffer pad 34. The first buffer pad 34 can buffer the collision to prevent damage to the mobile frame 3 or the robot. The first buffer pad 34 can be an air cushion, a rubber pad, a silicone pad or a cotton pad.

[0046] See also Figure 1-Figure 3The fixing frame 2 includes a second buckle 23, which is connected to the second placement platform 21 and is used to fix the battery 5 located on the fixing frame 2. Specifically, the second buckle 23 is fixed to the upper surface of the second placement platform 21, and the second buckle 23 is hook-shaped. Since the battery 5 used by the robot has a rotatable handle, in order to prevent the battery 5 from falling off the fixing frame 2 when the fixing frame 2 transports the battery 5, the handle can be buckled on the second buckle 23, so that the battery 5 is relatively fixed to the second placement platform 21 to ensure the safety of the battery 5. The second smooth bar 22 is located on the upper surface of the second placement platform 21, and the second smooth bar 22 extends in the horizontal direction. The battery 5 can be placed on the second smooth bar 22. When the second placement platform 21 is aligned with the battery compartment 6, the staff can flip the handle to disengage the buckle of the second buckle 23, and then push the battery 5 into the battery compartment 6 along the second smooth bar 22. The second smooth bar 22 allows the staff to push the battery 5 into the battery compartment 6 more smoothly. The second buffer pad 24 is installed on the side of the second placement table 21, and the second buffer pad 24 is located in the output direction of the second flow strip 22. When the fixing frame 2 is aligned with the battery compartment 6, the fixing frame 2 needs to be close to the battery compartment 6. In order to avoid collision between the fixing frame 2 and the robot, the side of the second placement table 21 with the second buffer pad 24 can be moved toward the battery compartment 6. Even if the robot comes into contact with the fixing frame 2, the robot will first contact the second buffer pad 24. The second buffer pad 24 can buffer the collision to prevent damage to the fixing frame 2 or the robot. The second buffer pad 24 can be an air cushion, a rubber pad, a silicone pad or a cotton pad.

[0047] See also Figure 4 In some embodiments, both the mobile frame 3 and the fixed frame 2 are provided with support members. When the mobile frame 3 is lowered to the second height of the fixed frame 2, the bottom ends of the support members 35 are flush with the bottom end of the main body 1. When the mobile frame 3 is at the second height, the bottom ends of the support members 35 are flush with the bottom end of the main body 1. At this time, all the support members 35 are in contact with the ground. The support members 35 of the mobile frame 3 can support the mobile frame 3 to ensure that the battery 5 can remain stable when moving between the mobile frame 3 and the battery compartment 6. When the mobile frame 3 is directly above the fixed frame 2, the support members 35 of the fixed frame 2 can support the fixed frame 2. In addition, the support members 35 can also adjust the angle and position of the mobile frame 3 relative to the battery compartment 6, so that the staff can accurately dock the mobile frame 3 with the battery compartment 6. Specifically, the support members 35 can be wheels or columns. In this embodiment, the support frame is a universal wheel.

[0048] See also Figure 3-4In some embodiments, the mobile frame 3 includes a first locking portion 36, which is located on the first placement platform 31, and the translation mechanism 42 is provided with a second locking portion 426. When the mobile frame 3 is located directly above the fixed frame 2, the translation mechanism 42 fixes the mobile frame 3 by docking the first locking portion 36 and the second locking portion 426 to prevent the mobile frame 3 from shaking or moving forward due to the vibration generated by the battery replacement vehicle when the staff pushes the battery replacement vehicle. In one embodiment, the first locking portion 36 is provided with a through hole, and the second locking portion 426 is provided with a retractable lock head. When the mobile frame 3 needs to be fixed, the second locking portion 426 can be controlled to extend the lock head so that the lock head passes through the through hole, so that the first locking portion 36 cannot move under the restriction of the lock head, thereby fixing the mobile frame 3 relative to the translation mechanism 42. In other embodiments, the second locking portion 426 may be an electromagnet, and the staff controls the second locking portion 426 to be energized so that the second locking portion 426 magnetically attracts the first locking portion 36 , thereby fixing the movable frame 3 .
