Detailed Description

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

Example 1

The invention provides a battery replacement station which comprises a vehicle carrying platform 100, a charging chamber 200 and battery replacement equipment (not shown in the figure). As shown in fig. 1, the vehicle-carrying platform 100 is used for allowing a vehicle 300 to drive in and park, two charging rooms 200 are provided in the battery replacement station in this embodiment and are respectively distributed on two sides of the vehicle-carrying platform 100, and the battery replacement device can shuttle between the two charging rooms 200 and the vehicle-carrying platform 100, and is used for detaching a battery pack 20 with a power shortage on the vehicle 300, transporting the battery pack 20 with the power shortage into the charging room 200 for charging, and transporting the battery pack 20 with the charging completed in the charging room 200 to the battery replacement point of the vehicle-carrying platform 100, and installing the battery pack 20 with the charging completed on the vehicle 300.

As shown in fig. 2, the charging room 200 in this embodiment includes two sets of charging racks 201, the two sets of charging racks 201 are symmetrically arranged, a battery transfer device 202 is disposed between the two sets of charging racks 201, and after the battery transfer device 202 obtains the battery pack 20 with a power loss from the battery replacement equipment, the battery pack 20 is carried to a position corresponding to the charging rack 201 by a lifting movement, or the battery pack 20 with a completed charging is taken out from a position corresponding to the charging rack 201, and then the battery pack 20 is sent to the battery replacement equipment. By adopting the structural layout, on the premise of not increasing the number of the battery transfer devices 202, the corresponding number of the battery charging bin 10 on the battery transfer devices 202 and the charging rack 201 is increased as much as possible, so that the number of the battery packs 20 which can be carried in the charging rack 201 is increased. Wherein, the charging frame 201 comprises a plurality of battery charging positions 10 arrayed along the vertical direction.

The specific structure of the battery charging bin 10 is shown in fig. 3, and it includes a bin body 1, a first belt moving mechanism 2 and a carrying portion 3. Wherein, position body 1 is used for holding battery package 20, is equipped with battery access & exit 11 in position body 1's one end that is close to battery transfer device 202 for supply battery package 20 to move in or shift out, and the lower surface of position body 1 is equipped with bottom plate 12, and first belt moving mechanism 2 and bearing part 3 all are set up on bottom plate 12. In other embodiments, the bottom plate 12 may not be disposed on the lower surface of the magazine body 1, as long as a corresponding frame structure capable of carrying the first belt moving mechanism 2 and the carrying portion 3 is disposed.

First belt moving mechanism 2 comprises two rows of belt pulleys, the belt on the belt pulley is used for bearing battery package 20, and can be through the rotation of first belt moving mechanism 2's action wheel, drive battery package 20 and remove in position of storehouse body 1, the route that drives battery package 20 through first belt moving mechanism 2 and remove is first route A, first route A extends to the one side that battery access & exit 11 was kept away from to position of storehouse body 1 from battery access & exit 11 department, with the drive through first belt moving mechanism 2, the purpose of realizing transporting battery package 20 between position of storehouse body 1 is inside to battery access & exit 11. Because the battery charging bin 10 has the functions of moving the battery pack 20 into the bin body 1 from the battery entrance 11 and moving the battery pack 20 in the bin body 1 out from the battery entrance 11, the corresponding battery transfer device 202 does not need to be provided with cantilever extending structures such as a double extending mechanism for taking and placing the battery pack 20, and the structure of the battery transfer device 202 is simplified. Meanwhile, the position of the battery pack 20 in the bin body 1 can be adjusted through the first belt moving mechanism 2, and the position of the battery pack 20 in the bin body 1 is more accurate and controllable due to the arrangement of the first belt moving mechanism 2. Meanwhile, the first belt moving mechanism 2 is controlled to start and stop, so that accurate positioning of the battery packs 20 of various models in the bin body 1 can be realized, and the battery charging bin 10 can be suitable for bearing the battery packs 20 of various models.

The support parts 3 are distributed on both sides or in the middle of the first belt moving mechanism 2 along the width direction of the battery pack 20 to be offset from the first belt moving mechanism 2, and the support parts 3 function to support the battery pack 20 to share the weight of the battery pack 20 supported by the first belt moving mechanism 2.

In this embodiment, as shown in fig. 5 and fig. 6, the first belt moving mechanism 2 is capable of lifting relative to the bearing portion 3, when the first belt moving mechanism 2 drives the battery pack 20 to move, the height of the first belt moving mechanism 2 is higher than that of the bearing portion 3, so as to avoid the bottom of the battery pack 20 from rubbing against the bearing portion 3 to generate a large resistance, and after the battery pack 20 is moved in place, the height of the first belt moving mechanism 2 is lower than that of the bearing portion 3, so that most of the weight of the battery pack 20 directly acts on the bearing portion 3, thereby avoiding the first belt moving mechanism 2 bearing the weight of the battery pack 20 for a long time, and improving the durability of the first belt moving mechanism 2. Meanwhile, by disposing the battery pack 20 on the carrying section 3, the positioning reliability of the battery pack 20 with respect to the battery charging station 10 can be improved. In other embodiments, the bearing portion 3 may not be provided if various disadvantages resulting from the first belt moving mechanism 2 bearing the battery pack 20 for a long period of time are not taken into consideration.

How to adjust the height of the first belt moving mechanism 2 relative to the supporting portion 3 is achieved in this embodiment by driving the first belt moving mechanism 2 to wholly lift through the lifting driving mechanism, and the specific structure of the lifting driving mechanism can refer to the prior art, and therefore details are not described herein again.

As shown in fig. 4, the battery charging bay 10 further includes a first gear stop mechanism 71 and a first in-position sensor (not shown). The first stopping mechanism 71 is also arranged on the surface of the bottom plate 12 of the bin body 1, the specific position of the first stopping mechanism 71 is arranged at one end far away from the battery access 11 along the first path a, the first stopping mechanism 71 is used for stopping the battery pack 20 at a first arrival point on the first path a, so that the battery pack 20 is accurately stopped at a preset arrival point in a physical limiting manner, and the structure is simple and reliable. In this embodiment, the height of the first stopping mechanism 71 in the non-stopping state may be lower than the bottom surface of the battery pack 20, and when the battery pack 20 needs to be stopped, the first stopping mechanism 71 is raised to be higher than the bottom surface of the battery pack 20, so as to achieve the purpose of physical limitation, and the battery pack 20 is accurately stopped at the first arrival point. In other embodiments, the height of the first stop mechanism 7 may be fixed, i.e. maintained in a stop state, and the height of the first stop mechanism 71 is higher than the bottom surface of the battery pack 20.

The first in-place sensor is arranged on the first stopping mechanism 71 and used for detecting whether the battery pack 20 is located at the first arrival point, and the purpose of actively monitoring the position of the battery pack 20 is achieved through the first in-place sensor, so that the time when the battery pack 20 arrives at the first arrival point under the driving of the first belt moving mechanism 2 is obtained in time, and the control precision is improved. Specifically, the first in-place sensor can generate a first signal when the battery pack 20 is located at the first in-place point, and the first signal is transmitted to the control motor for the movement of the first belt through a wire, so that the first belt moving mechanism 2 stops operating. By means of the closed-loop control, the accuracy of the first belt moving mechanism 2 for driving the battery pack 20 to stop at the first arrival point can be improved, and the automation degree is high. Wherein, the first in-place sensor preferably adopts a non-contact sensing sensor, so as to avoid obstructing the normal movement of the battery pack 20.

The battery charging bin 10 further comprises a first electric connector 4, the first electric connector 4 is arranged on the bin body 1 and is used for being in butt joint with a second electric connector on the battery pack 20, and therefore the purpose that the battery charging bin 10 charges the battery pack 20 is achieved.

In the present embodiment, as shown in fig. 3, the first electrical connector 4 is disposed on the back side of the battery charging position 10, i.e. the side away from the battery inlet 11, and the number of the first stopping mechanisms 71 is two, and the two stopping mechanisms are respectively distributed on the left and right sides of the first electrical connector 4. When the battery pack 20 moves to the first position point along with the driving of the first belt moving mechanism 2, the first electrical connector 4 can be electrically connected with the second electrical connector on the battery pack 20. In this embodiment, a second stopping mechanism 72 may be further disposed in the storage body 1, the second stopping mechanism 72 is specifically located between the first arrival point and the battery exit 11, and after the first electrical connector 4 is electrically connected to the second electrical connector, the second stopping mechanism 72 moves to the first path a to stop the battery pack 20 from moving toward the battery exit, that is, to stop the battery pack 20. In this embodiment, the height of the second stopping mechanism 72 in the non-stopping state needs to be lower than the bottom surface of the battery pack 20, and when the battery pack 20 needs to be stopped, the second stopping mechanism 72 rises to be higher than the bottom surface of the battery pack 20, so as to achieve the purpose of physical limiting and prevent the battery pack 20 from separating from the warehouse exit body 1.

In other embodiments, battery charging station 10 may be adapted to carry and charge a variety of battery packs. The multiple types of battery packs are different in length, width and height, and the second stopping mechanism 72 can move along the first path a, so that the multiple types of battery packs can be physically limited after the second stopping mechanism 72 rises.

On this basis, the present embodiment provides a battery replacement control method corresponding to the structure of the battery charging bin 10, which specifically includes the following steps:

s11, the first belt moving mechanism 2 is controlled to start, so that the battery pack 20 loaded on the surface thereof moves along the first path a and enters the battery charging bin 10.

And S12, controlling the first belt moving mechanism 2 to stop operating after the battery pack 20 moves along the first path A to electrically connect the second electric connector on the battery pack 20 with the first electric connector 4.

And S13, after the second electric connector on the battery pack is electrically connected with the first electric connector 4, controlling the second stopping mechanism to ascend relative to the bin body so as to stop the battery pack from retreating along the direction far away from the first electric connector 4.

According to the battery replacement control method, the first belt moving mechanism 2 arranged in the bin body 1 is used for moving the battery pack 20 to drive the battery pack 20 to move and be butted with the first electric connector 4, the position accuracy and the butting reliability of the battery pack 20 in the bin body 1 and the first electric connector 4 are improved, and the purpose that the first electric connector 4 is electrically connected with the second electric connector on the battery pack 20 when the battery packs 20 of various types move in place in the bin body 1 can be achieved only by controlling the start and stop of the first belt moving mechanism 2.

In order to ensure the positioning effect of the first electrical connector 4 and the second electrical connector, after the first belt moving mechanism 2 drives the battery pack 20 to move so as to make the second electrical connector of the battery pack 20 abut against the first electrical connector 4 of the battery charging bin 10, the second stopping mechanism 72 is used for physically limiting the battery pack 20, so that the first electrical connector 4 is accurately stopped to be kept in close contact with the second electrical connector, and the battery pack 20 is prevented from moving over to excessively press the first electrical connector 4 to damage the first electrical connector 4 and/or the second electrical connector.

The second stopper mechanism 72 can prevent the battery pack 20 from moving in the direction of the battery inlet 11 and being separated from the housing body 1 or the electrical connection from being lost. In this embodiment, the contact relationship of the second stopping mechanism 72 for positioning and contacting the battery pack 20 is as shown in fig. 7, and it can be seen from the figure that the second stopping mechanism 72 contacts the battery pack 20 through the inclined surface 7a, so that in the process of rising of the second stopping mechanism 72, an acting force for driving the battery pack 20 to press towards the first electrical connector 4 can be generated, and the electrical connection effect of the battery pack 20 is improved.

In addition, after the first belt moving mechanism 2 drives the battery pack 20 to move to the first position, the first belt moving mechanism 1 can also enable the battery pack 20 to be completely carried on the carrying part 3 and be kept at the first position by a relative descending mode.

Example 2

This embodiment also provides a battery charging chamber, which has a structure substantially the same as that of the battery charging chamber provided in embodiment 1, except that, as shown in fig. 8 and 9, in this embodiment, the first electrical connector 4 is disposed on a side of the chamber body 1 adjacent to the battery access 11. Therefore, the first belt moving mechanism 2 moves the battery pack 20, so that the second electrical connector on the battery pack 20 is not directly connected to the first electrical connector 4.

The battery charging bin in the embodiment further comprises a second belt moving mechanism 5 arranged on the bottom plate 12 of the bin body 1, the extending direction of the second belt moving mechanism 5 is perpendicular to the first belt moving mechanism 2, and the second belt moving mechanism 5 is arranged between the two groups of belt pulleys of the first belt moving mechanism 2, so that the purpose of staggered arrangement with the first belt moving mechanism 2 is achieved. The second belt moving mechanism 5 is used for carrying the battery pack 20 and can drive the battery pack 20 to move along the second path B. As can be seen from the figure, the second path B in this embodiment is perpendicular to the first path a and extends to the position of the first electrical connector 4. With the arrangement, after the battery pack 20 is moved into the first arrival point of the battery charging bin 10 by the first belt moving mechanism 2, the battery pack 20 is further moved along the second path B by the arranged second belt moving mechanism 5 until the battery pack is butted with the first electric connector 4, so that the charging purpose is realized.

Specifically, in order to enable the first belt moving mechanism 2 and the second belt moving mechanism 5 to drive the battery pack 20, the belt surfaces of the first belt moving mechanism 2 and the second belt moving mechanism 5 may be located at the same height but higher than the bearing portion 3. Or, the belt surfaces of the first belt moving mechanism 2 and the second belt moving mechanism 5 and the bearing part 3 are all located at the same height, and at this time, in order to reduce the friction force on the surface of the bearing part 3 and avoid the battery pack 20 from generating large friction with the surface of the bearing part 3 under the driving of the first belt moving mechanism 2 or the second belt moving mechanism 5, the upper surface of the bearing part 3 is provided with a ball.

This embodiment provides a scheme of relative lift: the first belt moving mechanism 2 is capable of lifting relative to the second belt moving mechanism 5, when the first belt moving mechanism 2 drives the battery pack 20 to move, the height of the first belt moving mechanism 2 is higher than that of the second belt moving mechanism 5, so that the bottom of the battery pack 20 is prevented from generating large resistance due to friction relative to the belt surface of the second belt moving mechanism 5, after the battery pack 20 moves to the first arrival point, the height of the first belt moving mechanism 2 is lower than that of the second belt moving mechanism 5, so that the battery pack 20 is borne by the second belt moving mechanism 5, and the second belt moving mechanism 5 can drive the battery pack 20 to move along the second path B.

How to adjust the height of the first belt moving mechanism 2 relative to the second belt moving mechanism 5 is achieved by driving the first belt moving mechanism 2 to wholly lift through the lifting driving mechanism in this embodiment, and the specific structure of the lifting driving mechanism can refer to the prior art, so detailed description is omitted here. Of course, the second belt moving mechanism 5 may be moved up and down with respect to the first belt moving mechanism 2 by providing the lifting/lowering drive mechanism to the second belt moving mechanism 5.

In other embodiments, the battery charging bin 10 may be adapted to support and/or charge a plurality of types of battery packs, where the plurality of types of battery packs may have different lengths, widths, and heights, and at this time, the second stopping mechanism 72 may further move along the first path a, so that physical limitation on the plurality of types of battery packs may be achieved after the second stopping mechanism 72 rises.

On this basis, the present embodiment also provides a battery replacement control method corresponding to the structure of the battery charging bin 10, which specifically includes the following steps:

s21, the first belt moving mechanism 2 is controlled to start, so that the battery pack 20 loaded on the surface thereof moves along the first path a and enters the battery charging bin 10.

And S22, when the battery pack 20 moves to the right position along the first path A, controlling the first belt moving mechanism 2 to stop running, and simultaneously controlling the second belt moving mechanism 5 to bear the battery pack 20 to drive the battery pack 20 to move along the second path B.

S23, when the battery pack 20 moves along the second path B to electrically connect the second electrical connector with the first electrical connector 4, controlling the second belt moving mechanism 5 to stop operating.

According to the power exchange control method, the first belt moving mechanism 2 and the second belt moving mechanism 5 are arranged in the bin body 1 simultaneously to move the battery pack 20 along different paths, so that the battery pack 20 is driven to move and butt-joint to the first electric connector 4, the position accuracy and the butt-joint reliability of the battery pack 20 in the bin body 1 and the first electric connector 4 are improved, and the power exchange control method is particularly suitable for the situation that the first electric connector 4 is arranged on the adjacent side of the battery access 11 of the bin body 1.

The second stopping mechanism 72 is disposed on the second path B, and after the first electrical connector 4 and the second electrical connector are contacted to realize electrical connection, the second stopping mechanism 72 moves onto the second path B and is used for stopping the battery pack 20 from moving in a direction away from the first electrical connector 4. The purpose of the second stop mechanism 72 is to improve the reliability of the positioning and electrical connection of the battery pack 20 after the battery pack 20 is mated with the first electrical connector 4 along the second path B. The specific structures of the first stop mechanism 71 and the second stop mechanism 72 can be seen from the structures provided by the first stop mechanism 71 and the second stop mechanism 72 in embodiment 1.

In this embodiment, the first in-position sensor is disposed on the first stopping mechanism, and is capable of generating a first signal when the battery pack 20 is located at the first in-position point, and the first signal is used to control to stop the operation of the first belt moving mechanism 2, or to control to make the height of the first belt moving mechanism 2 lower than that of the second belt moving mechanism 5, or to synchronize the two actions. The first signal is used as a basis to control the start and stop of the first belt moving mechanism 2 or lift relative to the second belt moving mechanism 5, so that the battery pack 20 can be reliably borne on the second belt moving mechanism 5, and the purpose of accurate control is achieved.

The first signal may also serve as a basis for driving the second belt moving mechanism 5 to ascend with respect to the first belt moving mechanism 2. After the first in-place sensor generates the first signal, the second belt moving mechanism 5 is raised, so that the battery pack 20 is carried on the second belt moving mechanism 5, and the second belt moving mechanism 5 is started to move the battery pack 20.

In this embodiment, the battery charging bay 10 further includes a second in-position sensor (not shown) disposed at an end of the second path B near the first electrical connector 4, the second in-position sensor being configured to detect whether the battery pack 20 is located at a second in-position point.

Specifically, the second in-place sensor can generate a second signal when the battery pack 20 is located at the second in-place point, and the second signal is used for controlling the second belt moving mechanism 5 to stop running so as to stop running of the second belt moving mechanism 5 in time after the battery pack 20 is moved in place. By means of closed-loop control, the position accuracy of the second belt moving mechanism 5 when the battery pack 20 is driven to stop being electrically connected with the first electrical connector 4 is improved, and the situation that the second electrical connector is damaged due to excessive extrusion on the second electrical connector after the battery pack 20 moves over the position is prevented.
