Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The power exchanging apparatus 100 and the power exchanging station 200 according to the present invention are described below with reference to fig. 1 to 15. The power exchanging station 200 is an energy station for charging and exchanging the battery 300 of the electric vehicle or the electric engineering vehicle. When the battery 300 is charged, the battery 300 is not loaded on the vehicle 400, but the charging is completed in the battery exchanging station 200. The battery 300 is replaced by removing the battery 300 from the vehicle 400 after the vehicle 400 enters the battery replacement station 200, and replacing another set of full battery 300. It can also be understood simply as vehicle electrical separation.
Referring to fig. 1, a power exchange station 200 according to an embodiment of the present invention includes a storage bin 210, a lane 220, a beam 230, and a power exchange device 100. The power exchanging station 200 may be used for exchanging power for a new energy passenger car, or may be used for exchanging power for an electric engineering car (for example, heavy truck, excavator, etc.), that is, the vehicle described below may be a new energy passenger car, or may be an electric engineering machine.
Specifically, the storage bin 210 is adapted to charge the battery 300. It will be appreciated that when the battery 300 is replaced by the battery replacement station 200, the battery 300 of the vehicle 400 may be removed and placed in the storage compartment 210 for charging, and the full battery 300, which is fully charged in the storage compartment 210, may be placed on the vehicle 400 to provide power to the vehicle 400.
Referring to fig. 3 and 5, a vehicle 400 is adapted to park on the lane 220. Of course, the vehicle 400 may be parked in the lane 220 near the storage compartment 210 to facilitate the replacement of the battery 300 by the power conversion device 100 for the vehicle 400. Referring to fig. 3 and 4, a cross member 230 is coupled to the top of the storage bin 210, for example, the cross member 230 is coupled to the upper ends of the columns of the storage bin 210. At least a portion of the cross beam 230 is located above the lane 220. The cross beam 230 is provided with a first rail 231, i.e. the cross beam 230 may be used to support the first rail 231. The power conversion device 100 is adapted to move along the first track 231 on the beam 230, that is, the first track 231 defines a movement track of the power conversion device 100, so as to facilitate the movement of the power conversion device 100 to the target position. For example, referring to fig. 2, the first rail 231 extends in the X direction, and the power conversion device 100 may move in the X direction.
Further, as shown in connection with fig. 7-9, the power conversion device 100 may include a frame 110, a running gear 120, a translation mechanism 112, a first grasping mechanism 130, and a second grasping mechanism 140.
As shown in fig. 7 and 8, the traveling mechanism 120 is disposed on the frame 110, so that the frame 110 can move smoothly along the first rail 231. It should be noted that, when the frame moves along the first track, if the frame is in direct contact with the first track, there is a large friction force between the frame and the first track, and there is a risk of unsmooth movement, and by setting the running mechanism 120, the running mechanism 120 may be used as an intermediate transmission component to reduce the friction force between the frame 110 and the first track 231, and meanwhile, the running mechanism 120 may also be used as a driving component to provide a power source for movement of the frame 110. The first rail 231 extends in a first direction in which the carriage 110 is movable.
As shown in connection with fig. 7 and 9, the translation mechanism 112 is connected to both the first gripping mechanism 130 and the second gripping mechanism 140. In some examples, the frame 110 may include: a main frame 111 and a second driving unit 113. The main frame 111 is connected to the travelling mechanism 120, the main frame 111 moves along a first direction, the translation mechanism 112 is movably connected to the main frame 111, the translation mechanism 112 moves along a second direction, the first direction is perpendicular to the second direction, and the second driving unit 113 is used for driving the translation mechanism 112 to move.
It should be explained that the translation mechanism 112 may move in two directions perpendicular to each other, that is, the translation mechanism 112 moves along the first direction under the driving of the main frame 111; the translation mechanism 112 moves in the second direction under the drive of the second drive unit 113. For example, referring to fig. 7, the first direction may be the X direction and the second direction may be the Y direction, so that the first and second grabbing mechanisms 130 and 140 may be aligned with the battery mounting position on the vehicle 400 or the moving device 240 through adjustment in two directions, thereby achieving the purpose of precisely taking the battery 300. Further, the translation mechanism 112 is horizontally fixed to the main frame 111, and the first gripping mechanism 130 and the second gripping mechanism 140 are disposed at the bottom of the translation mechanism 112.
The first and second gripping mechanisms 130, 140 each have the function of gripping the battery 300 and releasing the battery 300, for example, the first and second gripping mechanisms 130, 140 are adapted to grip a full battery 300 in the storage bin 210 or a battery 300 that is deficient in power on the vehicle 400 parked on the lane 220. The first grabbing mechanism 130 and the second grabbing mechanism 140 may be a manipulator or an electromagnetic chuck.
It should be further noted that, when the first gripping mechanism 130 and the second gripping mechanism 140 are simultaneously disposed on the same power conversion device 100, and when the initial position of the power conversion device 100 is above the vehicle 400, the power conversion process may be:
the first step, the first grabbing mechanism 130 of the power conversion device 100 takes out the battery 300 with the power shortage on the vehicle 400, at this time, the power conversion device 100 can return to the storage bin 210 with the battery 300 with the power shortage, the first grabbing mechanism 130 puts the battery 300 with the power shortage into the storage bin 210, and the storage bin 210 charges the battery 300 with the power shortage; meanwhile, the second grabbing mechanism 140 of the power conversion device 100 may grab the full battery 300 in the storage bin 210;
in a second step, the power exchanging device 100 may move to the position of the vehicle 400 with the full battery 300, and the second gripping mechanism 140 may put the full battery 300 on the vehicle 400 to complete the power exchanging.
Of course, when the initial position of the power exchanging device 100 is above the storage bin 210, the power exchanging process may be:
the first step, after the first grabbing mechanism 130 of the power conversion device 100 grabs the full-charge battery 300 from the storage bin 210, the power conversion device 100 may drive the full-charge battery 300 to move above the lane 220;
in the second step, the second grabbing mechanism 140 of the power conversion device 100 may take out the battery 300 with the power shortage on the vehicle 400, the first grabbing mechanism 130 may mount the battery 300 with the power shortage on the vehicle 400, the power conversion device 100 may return to the storage compartment 210 with the battery 300 with the power shortage, the second grabbing mechanism 140 may release the battery 300 with the power shortage into the storage compartment 210, and the storage compartment 210 may charge the battery 300 with the power shortage.
In this way, the power exchanging device 100 completes the transportation of the full battery 300 and the insufficient battery 300 through one reciprocating process, thereby simplifying the scheduling procedure of the power exchanging device 100, shortening the waiting time of the vehicle 400 and improving the power exchanging efficiency of the power exchanging station 200.
When a driver of the vehicle parks, the vehicle does not park in the lane according to the standard state, the central axis of the vehicle deviates from the central axis of the lane, namely, the direction of the vehicle head is provided with an acute angle with the front side direction, so that the gesture of the battery to be replaced is different from the grabbing angles of the first grabbing mechanism and the second grabbing mechanism, and if the grabbing angles of the first grabbing mechanism and the second grabbing mechanism are not adjusted, the first grabbing mechanism and the second grabbing mechanism cannot accurately grab the battery.
To cope with this problem, the first and second grasping mechanisms 130 and 140 are rotatably connected with the frame 110, which facilitates the first and second grasping mechanisms 130 and 140 to adjust the angle at which the battery 300 is grasped. It should be noted that, when the frame 110 moves along the first track 231, the frame 110 may drive the first grabbing mechanism 130 and the second grabbing mechanism 140 to move, that is, the first grabbing mechanism 130 and the second grabbing mechanism 140 may move synchronously along the first track 231, so as to facilitate moving the first grabbing mechanism 130 and the second grabbing mechanism 140 to the target position; meanwhile, the first grabbing mechanism 130 and the second grabbing mechanism 140 can rotate relative to the frame 110, so that when the placing position of the target battery 300 is in an inclined state (or the battery 300 has a corner in the horizontal direction), the first grabbing mechanism 130 and the second grabbing mechanism 140 can be aligned with the battery 300 by adjusting the corners of the first grabbing mechanism 130 and the second grabbing mechanism 140, and the purpose of accurate grabbing is achieved.
Referring to fig. 9, the power conversion device 100 further includes a rotation mechanism 150, where the rotation mechanism 150 is connected to the first grabbing mechanism 130 and the second grabbing mechanism 140, and the rotation mechanism 150 can enable the first grabbing mechanism 130 and the second grabbing mechanism 140 to rotate synchronously. On the one hand, the revolving mechanism 150 can drive the first grabbing mechanism 130 and the second grabbing mechanism 140 to rotate, so that the first grabbing mechanism 130 and the second grabbing mechanism 140 after the rotation angle is adjusted can be aligned with the battery 300; on the other hand, the rotation mechanism 150 can also enable the first grabbing mechanism 130 and the second grabbing mechanism 140 to synchronously rotate, that is, the rotation mechanism 150 can synchronously adjust the first grabbing mechanism 130 and the second grabbing mechanism 140 after one-time adjustment, so that the gesture adjusting process of the power conversion device 100 can be shortened, and the power conversion program is simplified.
For example, referring to fig. 13, when the driver of the vehicle 400 is parked in the lane 220, the vehicle 400 is not parked in the power exchanging station 200 in a standard state, the central axis of the vehicle 400 deviates from the central axis of the lane 220, and when the vehicle 400 is powered up, taking an initial position of the power exchanging device 100 above the storage compartment 210 as an example, the entire power exchanging process may be:
a power-change preparation stage: after the first grabbing mechanism 130 of the power conversion device 100 grabs the full-charge battery 300 from the storage bin 210, the power conversion device 100 can drive the full-charge battery 300 to move to the upper side of the lane 220, and wait for the vehicle 400 to enter the lane 220;
taking the power shortage battery 300: the vehicle 400 to be replaced is driven into the lane 220, and the position of the second gripping mechanism 140 is adjusted according to the actual position of the battery 300 of the vehicle 400 due to the deviation of the position of the vehicle 400 after the vehicle 400 is stopped from the ideal position. Here, the relative position of the power exchanging device 100 on the first track 231 may be adjusted first; then, the rotation angle of the second grabbing mechanism 140 is adjusted by using the rotation mechanism 150, so that the purpose that the second grabbing mechanism 140 is completely aligned with the power-deficient battery 300 is achieved, and the second grabbing mechanism 140 is driven to move at the moment, and the second grabbing mechanism 140 can accurately grab the power-deficient battery 300. After the second grabbing mechanism 140 grabs the battery 300, the battery 300 can be lifted.
Full charge battery 300: the relative position of the power conversion device 100 on the first rail 231 is adjusted, so that the first grabbing mechanism 130 moves to the upper side of the vehicle 400 along the first rail 231, and the rotation angle of the first grabbing mechanism 130 is adjusted in the same step while the rotation angle of the second grabbing mechanism 140 is adjusted, that is, the rotation angle of the first grabbing mechanism 130 is the same as the rotation angle of the second grabbing mechanism 140, at this time, the rotation angle of the first grabbing mechanism 130 is not required to be adjusted, the first grabbing mechanism 130 is only required to be adjusted to the position right above the vehicle 400, and the first grabbing mechanism 130 can complete the power conversion of the vehicle 400 by placing the full battery 300 in the battery mounting position of the vehicle 400.
And (3) ending stage: the power exchanging device 100 drives the battery 300 with the power shortage captured by the second capturing mechanism 140 to move to the storage compartment 210, and the second capturing mechanism 140 returns the battery 300 with the power shortage to the storage compartment 210 to charge the battery 300 with the power shortage.
Thereby, the power exchange station 200 completes the power exchange.
Of course, when the driver of the vehicle 400 parks in the lane 220, the vehicle 400 parks in the power exchanging station 200 in a standard state, the central axis of the vehicle 400 is the same as the central axis extending direction of the lane 220, and the rotation angles of the first and second gripping mechanisms 130, 140 do not need to be adjusted when the vehicle 400 is powered. For example, referring to fig. 10, taking an example of the initial position of the power exchanging device 100 above the storage bin 210, the whole power exchanging process may be:
a power-change preparation stage: after the first grabbing mechanism 130 of the power conversion device 100 grabs the full-charge battery 300 from the storage bin 210, the power conversion device 100 can drive the full-charge battery 300 to move to the upper side of the lane 220, and wait for the vehicle 400 to enter the lane 220;
taking the power shortage battery 300: the vehicle 400 to be replaced is driven into the lane 220, and since the vehicle 400 is parked at the standard position, the relative position of the power conversion device 100 and the first rail 231 can be adjusted only, that is, the first grabbing mechanism 130 or the second grabbing mechanism 140 is adjusted to be right above the battery mounting position of the vehicle 400, and the rotation angles of the first grabbing mechanism 130 and the second grabbing mechanism 140 are not required to be adjusted.
