The embodiment discloses a method for hoisting a battery box 41, as shown in fig. 1,2 and 3, which may include:
Step S11, based on the arrival of the vehicle 40 at the power change area, the cart unit 23 moves toward the battery box 41;
step S12, based on the trolley unit 23 moving to the hoisting position, acquiring the posture of the battery box 41 on the vehicle 40;
Step S13, based on the first inclination of the battery box 41, the lifting unit 24 descends; wherein the first inclination includes that the top end of the battery box 41 is inclined towards one end far away from the cart unit 21, and the included angle between the top surface of the battery box 41 and the horizontal plane is smaller than a first set value; the cart unit 21 is detachably connected with the cart guide rail unit 22; the trolley unit 23 is detachably connected with one end of the trolley guide rail unit 22 away from the cart unit 21; the carriage rail unit 22 is elongated or shortened in the length direction; when the carriage rail unit 22 is extended, the end of the carriage rail unit 22 away from the cart unit 21 is lower than the end of the carriage rail unit 22 close to the cart unit 21;
step S14, based on the lifting unit 24 being lowered to the gripping position, the battery box 41 is gripped.
With the popularization and development of the new energy vehicle 40, how to supply the vehicle 40 with continuous electric power becomes a problem that must be solved. At present, two energy supplementing modes of electricity changing and charging are mainly adopted. The energy supplementing mode of changing electricity is widely adopted because of the characteristics of high speed and simple operation. And the battery box 41 is called by adopting a cable to replace the top hanging type electricity, and error compatibility is realized by utilizing the flexibility of the cable when the top hanging type electricity is close to sitting. Has the characteristics of simple technology and low cost, and is widely applied to actual production. During operation of the vehicle 40, the battery box 41 is often tilted due to road bumps, inertia, or the like. In the process of top-hung power conversion, the inclined battery box 41 is difficult to grasp or unstable to grasp due to the fact that the angle and the direction of the lifting unit 24 cannot be adjusted, and the risk that the battery box 41 falls exists. In order to prevent this, the application discloses a method and a device for hoisting the battery box 41.
In the present embodiment, as shown in fig. 2 and 3, the apparatus applied to the method of lifting the battery box 41 may include the electricity exchanging assembly 20. The battery exchange assembly 20 is used to hoist and transport the battery box 41. The power exchanging assembly 20 may include a cart unit 21, a cart rail unit 22, a cart unit 23, and a hoist unit 24. Both the cart unit 21 and the cart unit 23 are movable along the track. The cart unit 23 is used to transfer the battery box 41 from the vehicle 40 to the cart unit 21 or from the cart unit 21 to the vehicle 40. The cart unit 21 is used to transfer the battery box 41 from the cart unit 23 to the cradle 12, or from the cradle 12 to the cart unit 23. Thereby enabling the transfer of the battery box 41 between the cradle 12 and the vehicle 40. The cart unit 21 is detachably connected to the cart rail unit 22. As shown in fig. 2, the carriage unit 23 is detachably connected to the right end of the carriage rail unit 22. The carriage rail unit 22 may be lengthened or shortened in the length direction for adjusting the position of the carriage unit 23. The carriage rail unit 22 is obliquely disposed, and the right end of the carriage rail unit 22 is lower than the left end of the carriage rail. The lifting unit 24 may include a gripping portion 241 for gripping the battery case 41.
As shown in fig. 2, the method for hoisting the battery box 41 includes steps S11 to S14. The above steps may be described in detail below:
in step S11, after the battery change vehicle 40 reaches the battery change area, the driver stops the battery change vehicle 40 at the designated battery change position. After the automatic control system confirms that the battery changing vehicle 40 meets the battery changing requirement, the trolley unit 23 is controlled to move along the trolley guide rail unit 22 to the position above the battery box 41 of the battery changing vehicle 40.
In step S12, when the cart unit 23 moves to the lifting position above the battery box 41 of the battery-changing vehicle 40, the automatic control system acquires the posture of the battery box 41 on the vehicle 40. The posture of the battery case 41 may include a direction and an angle in which the battery case 41 is inclined. The automatic control system acquires the direction and angle of inclination of the battery box 41, and then analyzes the data.
In step S13, as shown in fig. 2, when the top end of the battery box 41 is inclined to the right and the included angle between the top surface of the battery box 41 and the horizontal plane is smaller than the first set value, the battery box 41 is in the first inclined state. For example: the first set point may be 3-8 degrees. At this time, since the cart rail unit 22 is obliquely disposed, the right end of the cart rail unit 22 is lower than the left end of the cart rail. The bottom plane of the trolley unit 23 is basically parallel to the top surface of the battery box 41, the distance from the bottom side of the hoisting unit 24 to the top surface of the battery box 41 is equal, no adjustment is needed for the trolley unit 23, and when the hoisting unit 24 descends to grab the top of the battery box 41, all grabbing parts 241 of the hoisting unit 24 can be contacted with the top of the battery box 41, so that the battery box 41 can be grabbed more firmly.
In step S14, when the lifting unit 24 is lowered until the grasping portion 241 contacts the top surface of the battery box 41, the automatic control system may determine that the grasping portion 241 reaches the grasping position. The automatic control system issues an instruction for the grasping portion 241 to grasp the battery box 41.
In some embodiments, as shown in fig. 3, the battery box 41 hoisting method includes:
Step S15, based on the completion of the grabbing of the battery box 41 by the hoisting unit 24, the adjusting assembly 30 is moved to abut against the side of the carriage rail unit 22 away from the cart unit 21 and lift the carriage rail unit 22;
In step S16, the battery box 41 is moved to the charging stand 12 based on the angle between the carriage rail unit 22 and the horizontal plane being the first set angle.
In this embodiment, in step S15, after the gripping portion 241 of the lifting unit 24 grips the battery box 41, the automatic control system controls the adjusting unit 30 to move to the lower right end of the cart rail unit 22 to abut against the bottom surface of the cart rail unit 22 before the battery box 41 is lifted, as shown in fig. 3 and 4. The adjustment assembly 30 may be of a ramp design, as shown in fig. 4, with the height of the adjustment assembly 30 ramp increasing from the side proximal to the trolley track to the side distal from the trolley track. Thus, the right end of the cart rail unit 22 can be lifted smoothly by the inclined surface, thereby adjusting the cart rail unit 22 to be horizontal.
In step S16, when the angle between the carriage rail unit 22 and the horizontal plane is set to be smaller than or equal to the first set angle, the carriage rail unit 22 is set to be approximately horizontal, and the battery box 41 can be moved. When the included angle between the trolley guide rail unit 22 and the horizontal plane is greater than the first set angle, the trolley guide rail unit 22 is not nearly horizontal yet, and needs to be adjusted continuously. The automatic control system obtains the included angle between the trolley guide rail unit 22 and the horizontal plane and compares the included angle with a first set angle (for example, the first set angle can be 3-8 degrees), and the system automatically adjusts until the included angle between the trolley guide rail unit 22 and the horizontal plane is smaller than or equal to the first set angle. The control system then controls the hoist unit 24 to slowly lift the battery box 41 upward. When the battery box 41 is lifted to the height set by the system, the lifting unit 24 stops lifting the battery box 41. As shown in fig. 2, the automatic control system controls the trolley guide rail unit 22 to retract leftward, driving the hoist unit 24 and the battery box 41 to move leftward together.
In some embodiments, as shown in fig. 2, the method for hoisting the battery box 41 further includes step S131, where step S131 includes:
Step S1311, based on the battery box 41 being the second inclination, the adjustment assembly 30 moves to abut against a side of the dolly rail unit 22 away from the cart unit 21 and lifts up the dolly rail unit 22; wherein the second inclination includes that the top end of the battery box 41 is inclined towards one end close to the cart unit 21, and the included angle between the top surface of the battery box 41 and the horizontal plane is smaller than a second set value;
In step S1312, the hoist unit 24 is lowered based on the side of the hoist unit 24 away from the carriage rail unit 22 being parallel to the top surface of the battery box 41.
In the present embodiment, as shown in fig. 2, step S131 may include step S1311 and step S1312. The above steps may be described in detail below:
In step S1311, as shown in fig. 2, when the top end of the battery box 41 is inclined to the left and the angle between the top surface of the battery box 41 and the horizontal plane is smaller than the second set value, the battery box 41 is in the second inclined state. For example: the second set point may be 3-8 degrees. At this time, since the tilting direction of the cart rail unit 22 is opposite to the tilting direction of the battery box 41, the distance from the bottom side of the hoist unit 24 to the top surface of the battery box 41 gradually decreases from left to right, and the hoist unit 24 may not grasp the battery box 41 or grasp the battery unstably because the grasping portions 241 cannot all contact the top surface of the battery box 41 at this time. Therefore, the lifting angle of the lifting unit 24 can be adjusted by adjusting the height of the carriage rail unit 22 so that the grasping portions 241 of the lifting unit 24 are all in contact with the top surface of the battery box 41, thereby making grasping firm. The automatic control system controls the adjusting assembly 30 to move leftwards, and moves to be abutted with the right side of the trolley guide rail unit 22 and lift the trolley guide rail unit 22, so that the bottom plane of the hoisting unit 24 is parallel to the top surface of the battery box 41, the distance from the bottom surface of the hoisting unit 24 to the top surface of the battery box 41 is basically equal, and when the grabbing part 241 of the hoisting unit 24 descends to the top of the battery box 41, the grabbing part 241 of the hoisting unit 24 can be contacted with the top of the battery box 41, and therefore each grabbing part 241 can grab the battery box 41, and grabbing is firmer.
In step S1312, when the bottom surface of the lifting unit 24 is substantially parallel to the top surface of the battery box 41 (for example, when the included angle between the bottom surface of the lifting unit 24 and the top surface of the battery box 41 is 3-8 degrees, the lifting unit may be considered as being substantially parallel), the control system controls the gripping portions 241 of the lifting unit 24 to descend, and at this time, each gripping portion 241 may contact with the top surface of the battery box 41, so that each gripping portion 241 may grip the battery box 41, and the gripping may be more secure.
In some embodiments, step S131 further comprises:
Step S1313, based on the lifting unit 24 being lowered to the gripping position, gripping the battery box 41;
Step S1314, based on the completion of gripping the battery box 41 by the hoisting unit 24, the adjustment assembly 30 moves in a direction away from the carriage rail unit 22 and is kept in abutment with the carriage rail unit 22;
In step S1315, the battery box 41 is moved to the charging stand 12 based on the angle between the carriage rail unit 22 and the horizontal plane being the second set angle.
In the present embodiment, as shown in fig. 2 and 3, step S131 may include steps S1313 to S1315. The above steps may be described in detail below:
In step S1313, after the lifting unit 24 descends to the point where the grabbing portion 241 contacts the top surface of the battery box 41, the sensor feeds back a signal to the automatic control system, and the automatic control system may determine that the grabbing portion 241 reaches the grabbing position and control the lifting unit 24 to stop descending. The automatic control system then controls the gripping portion 241 of the hoist unit 24 to grip the top of the battery box 41.
In step S1314, after the gripping portion 241 of the lifting unit 24 grips the battery box 41, the automatic control system controls the adjusting assembly 30 to move rightward and keep abutting against the trolley guide rail unit 22, and since the adjusting assembly 30 is inclined, when the adjusting assembly 30 moves rightward, the right end of the trolley guide rail unit 22 slowly descends, so that the trolley guide rail unit 22 is adjusted in the horizontal direction. This allows the trolley rail units 22 to be on the same horizontal plane and allows for a smoother operation of the hoist units 24 when hoisting batteries.
In step S1315, when the angle between the trolley rail unit 22 and the horizontal plane is the second set angle (for example, the second set angle may be 3-8 degrees), it is indicated that the trolley rail unit 22 has been adjusted to be nearly horizontal, and the battery box 41 may be moved. At this time, the automatic control system controls the hoist unit 24 to lift the battery box 41 upward. When the battery box 41 is lifted to the height set by the system, the lifting unit 24 stops lifting the battery box 41. As shown in fig. 2, the automatic control system controls the trolley guide rail unit 22 to retract leftward, driving the hoist unit 24 and the battery box 41 to move leftward together. When the battery box 41 moves into the cart unit 21, the automatic control system controls the cart unit 21 to move and drive the battery box 41 to move, and when the battery box 41 moves above the corresponding charging seat 12, the automatic control system controls the hoisting unit 24 to slowly place the battery box 41 on the charging seat 12.
In some embodiments, as shown in fig. 2 and 3, the method for hoisting the battery box 41 further includes step S132, where step S132 includes:
Step S1321, based on the battery box 41 being the third inclination, the adjustment assembly 30 moves to abut against a side of the dolly rail unit 22 away from the cart unit 21 and lifts up the dolly rail unit 22; wherein the third inclination comprises that the top end of the battery box 41 inclines towards the advancing direction of the vehicle 40, and the included angle between the top surface of the battery box 41 and the horizontal plane is smaller than a third set value; the adjusting assembly 30 includes a first adjusting unit 31, a second adjusting unit 32; the first adjusting unit 31 is detachably connected with the base assembly 10; the second adjusting unit 32 is detachably connected with the base assembly 10; the first adjusting unit 31 and the second adjusting unit 32 are sequentially arranged at intervals along the advancing direction of the vehicle 40;
Step S1322, based on the angle between the trolley guide rail unit 22 and the horizontal plane being a third set angle, the first adjusting unit 31 moves until the inclination direction of the hoisting unit 24 matches the third inclination direction;
In step S1323, the battery box 41 is grasped based on the inclination direction of the hoist unit 24 matching the third inclination direction.
In the present embodiment, as shown in fig. 2 and 3, step S132 may include steps S1321 to S1323. The above steps may be described in detail below:
In step S1321, when the top end of the battery box 41 is inclined toward the forward direction of the vehicle 40 (right front as shown in fig. 3) and the angle between the top surface of the battery box 41 and the horizontal plane is smaller than the third set value, the battery box 41 is in the third inclined state. At this time, as shown in fig. 3, the right end of the cart rail unit 22 is inclined downward, and the cart rail unit 22 is adjusted to be horizontal. The automatic control unit controls the adjusting assembly 30 to move to the right side of the trolley guide rail unit 22 to abut and lift the trolley guide rail unit 22, so that the trolley guide rail unit 22 is on the same horizontal plane. At this time, the top surface of the battery box 41 still forms an angle with the bottom surface of the hoist unit 24. At this time, the battery box 41 is gripped by the lifting unit 24, and the gripping portion 241 cannot fully contact the top surface of the battery box 41, so that the gripping is not firm. In order to avoid this, the adjusting assembly 30 may be provided to include a first adjusting unit 31, a second adjusting unit 32. The first adjusting unit 31 is detachably connected with the base assembly 10; the second adjusting unit 32 is detachably connected with the base assembly 10; the first and second adjusting units 31, 32 are disposed at intervals in order along the forward direction of the vehicle 40. The automatic control system may control the movement of the first and second adjusting units 31 and 32, respectively, so that the hoist unit 24 is adjusted to be substantially parallel to the top surface of the battery box 41 and the bottom surface of the hoist unit 24.
In step S1322, as shown in fig. 3 and 4, when the included angle between the trolley rail unit 22 and the horizontal plane thereof is a third set angle (for example, the third set angle may be 3-8 degrees), in order to make the bottom surface of the lifting unit 24 parallel to the top surface of the battery box 41, it is ensured that the gripping portion 241 of the lifting unit 24 is in full contact with the top surface of the battery box 41. The automatic control system controls the first adjusting unit 31 to move to the position below the trolley track unit on the side, close to the first adjusting unit 31, of the trolley track unit, and the trolley track unit is abutted and lifted. This allows the trolley rail unit on the first adjustment unit 31 side to be high and the trolley rail unit on the second adjustment unit 32 side to be low, so that the bottom surface of the lifting unit 24 is substantially parallel to the top surface of the battery box 41, and the battery box 41 is gripped more firmly.
In step S1323, when the bottom surface of the hoist unit 24 is substantially parallel to the top surface of the battery box 41, the automatic control system controls the hoist unit 24 to descend until the grasping portion 241 contacts the top surface of the battery box 41, and then the grasping portion 241 grasps the battery box 41. This makes it possible to make the grasping portions 241 of the hoist unit 24 all in contact with the top surface of the battery case 41, grasping the battery case 41 more firmly.
In some embodiments, as shown in fig. 2 and 3, step S132 further includes:
step S1324, based on the completion of the gripping of the battery box 41 by the hoisting unit 24, the second adjusting unit 32 moves to abut against the side of the carriage rail unit 22 away from the cart unit 21 and lifts the side of the carriage rail unit 22 close to the second adjusting unit 32;
in step S1325, the battery box 41 is moved to the charging stand 12 based on the angle between the carriage rail unit 22 and the horizontal plane being the third set angle.
In the present embodiment, as shown in fig. 2 and 3, step S132 may include step S1324 and step S1325. The above steps may be described in detail below:
In step S1324, as shown in fig. 3 and 4, after the gripping portion 241 of the hoisting unit 24 grips the battery box 41, the automatic control system controls the second adjusting unit 32 to move to the lower side of the trolley track unit on the side of the second adjusting unit 32, and abuts against and lifts the right end of the trolley track. This makes it possible to make the cart rail unit on the first adjustment unit 31 side and the cart rail unit on the second adjustment unit 32 side substantially on the same horizontal plane, and when the battery box 41 is lifted by the lifting unit 24, the battery box 41 is in a vertically non-inclined state. This allows the trolley rail units 22 to be on the same horizontal plane and allows for a smoother operation of the hoist units 24 when hoisting batteries.
In step S1325, as shown in fig. 3 and 4, when the automatic control system detects that the included angle between the trolley guide rail unit 22 and the horizontal plane is the third set angle (for example, the third set angle may be 3-8 degrees), the automatic control system determines that the trolley track on the side of the first adjusting unit 31 and the trolley track on the side of the second adjusting unit 32 are substantially on the same horizontal plane, and then the automatic control system controls the hoisting unit 24 to move the battery box 41 to the charging stand 12. This allows the hoisting unit 24 to operate more smoothly when hoisting the battery.
In some embodiments, the method for hoisting the battery box 41 further includes step S133, and step S133 includes:
step S1331, based on the fourth inclination of the battery box 41, the adjustment assembly 30 moves to abut against the side of the carriage rail unit 22 away from the cart unit 21 and lifts the carriage rail unit 22; wherein the fourth inclination comprises the inclination of the top end of the battery box 41 towards the opposite direction of the forward movement of the vehicle 40, and the included angle between the top surface of the battery box 41 and the horizontal plane is smaller than a fourth set value; the adjusting assembly 30 includes a first adjusting unit 31, a second adjusting unit 32; the first adjusting unit 31 is detachably connected with the base assembly 10; the second adjusting unit 32 is detachably connected with the base assembly 10; the first adjusting unit 31 and the second adjusting unit 32 are sequentially arranged at intervals along the advancing direction of the vehicle 40;
step S1332, based on the angle between the trolley guide rail unit 22 and the horizontal plane being a fourth set angle, the second adjusting unit 32 moves until the inclination direction of the hoisting unit 24 matches the fourth inclination direction;
step S1333, gripping the battery box 41 based on the inclination direction of the lifting unit 24 matching the fourth inclination direction.
In the present embodiment, as shown in fig. 2 and 3, step S133 may include steps S1331 to S1333. The above steps may be described in detail below:
In step S1331, when the top end of the battery box 41 is inclined toward the backward direction of the vehicle 40 (rearward left as shown in fig. 3) and the angle between the top surface of the battery box 41 and the horizontal plane is smaller than the fourth set value, the battery box 41 is in the fourth inclined state. At this time, as shown in fig. 3, the right end of the cart rail unit 22 is inclined downward, and the cart rail unit 22 is adjusted to be horizontal. The automatic control unit controls the adjusting assembly 30 to move to the right side of the trolley guide rail unit 22 to abut and lift the trolley guide rail unit 22, so that the trolley guide rail units 22 are substantially on the same horizontal plane. At this time, an included angle still exists between the top surface of the battery box 41 and the bottom surface of the trolley unit 23, and at this time, the lifting unit 24 still grabs the battery box 41, and the grabbing portion 241 cannot fully contact the top surface of the battery box 41, so that the grabbing is not firm. In order to avoid this, the adjusting assembly 30 may be provided to include a first adjusting unit 31, a second adjusting unit 32. The automatic control system can respectively control the first adjusting unit 31 and the second adjusting unit 32 to move, so that the first adjusting unit 31 or the second adjusting unit 32 extends below the track unit and is abutted with the track unit, and the trolley unit 23 is adjusted to a required state.
In step S1332, when the included angle between the trolley guide rail unit 22 and the horizontal plane is the fourth set angle (for example, the fourth set angle may be 3-8 degrees), in order to make the bottom surface of the trolley unit 23 substantially parallel to the top surface of the battery box 41, it is ensured that the grasping portion 241 of the lifting unit 24 is in full contact with the top surface of the battery box 41. The automatic control system controls the second adjustment unit 32 to move to the lower side of the corresponding trolley track, and to abut against and lift the trolley track. This makes it possible to make the cart rail on the second adjusting unit 32 side high and the cart rail on the first adjusting unit 31 side low, so that the bottom surface of the cart unit 23 is substantially parallel to the top surface of the battery box 41, and the battery box 41 is gripped more firmly.
In step S1333, when the bottom surface of the cart unit 23 is substantially parallel to the top surface of the battery box 41, the automatic control system controls the hoist unit 24 to descend until the grasping portions 241 all contact the top surface of the battery box 41, and then the grasping portions 241 grasp the battery box 41. This makes it possible to make the grasping portions 241 of the hoist unit 24 contact the top surface of the battery case 41, and the battery case 41 is grasped more firmly.
In some embodiments, step S133 further comprises:
Step S1334, based on the completion of gripping the battery box 41 by the hoisting unit 24, the first adjusting unit 31 is moved to abut against the side of the carriage rail unit 22 away from the cart unit 21 and lifts the side of the carriage rail unit 22 close to the first adjusting unit 31;
In step S1335, the battery box 41 is moved to the charging stand 12 based on the angle between the carriage rail unit 22 and the horizontal plane being the fourth set angle.
In the present embodiment, as shown in fig. 2 and 3, step S133 may include step S1334 and step S1335. The above steps may be described in detail below:
In step S1334, after the gripping portion 241 of the lifting unit 24 grips the battery box 41, the automatic control system controls the first adjusting unit 31 to move to the lower side of the trolley track on the side of the first adjusting unit 31, and to abut against and lift the trolley track. This allows the trolley track on the side of the first adjustment unit 31 to be raised to be substantially level with the trolley track on the side of the second adjustment unit 32. This allows the hoisting unit 24 to operate more smoothly when hoisting the battery.
In step S1335, when the automatic control system detects that the included angle between the trolley guide rail unit 22 and the horizontal plane is the fourth set angle (for example, the fourth set angle may be 3-8 degrees), the automatic control system determines that the trolley track on the side of the first adjusting unit 31 and the trolley track on the side of the second adjusting unit 32 are substantially on the same horizontal plane, and then the automatic control system controls the hoisting unit 24 to lift and move the battery box 41 to the charging stand 12. This allows the battery box 41 to be in a vertically non-inclined state during the transfer. Further, when the battery box 41 is placed on the charging stand 12, the alignment is accurate and no inclination occurs.
