The battery discharge device and the battery discharge apparatus described above will be described in detail below with reference to specific embodiments.

The battery pack discharging apparatus in this embodiment may include a discharging cabinet (not shown in the drawings) and a battery pack discharging device, the battery pack discharging device may include a platform 20, a mounting frame 30, and a conductive module, the platform 20 may be used to place the battery pack 10, the battery pack 10 includes a plurality of battery cells 101, and the plurality of battery cells 101 may be arranged along a first direction. Each cell 101 is provided with a positive electrode 1011 and a negative electrode 1012, and when the cell 101 is discharged, the discharge cabinet can be electrically connected with the positive electrode 1011 and the negative electrode 1012 respectively, so that the discharge can be performed. The mounting frame 30 may include a first supporting frame 31 and two second supporting frames 32, the second supporting frames 32 are mounted on the platform 20 and are perpendicular to the platform 20, and two ends of the first supporting frame 31 are respectively connected to one end of the second supporting frame 32 far away from the platform 20. That is, the mounting bracket 30 is an inverted U-shaped structure, and the first support frame 31 and the second support frame 32 may be integrally connected or detachably connected.
The conductive module may include a first conductive compact 40 and a second conductive compact 50, both the first conductive compact 40 and the second conductive compact 50 being mounted on the first support frame 31. In specific implementation, as shown in fig. 2, the first conductive pressing block 40 is provided with a conductive hole 41, and the discharge cabinet extends into the conductive hole 41 through a wire and is fixed to the first conductive pressing block 40 through a bolt, so that the wire is electrically connected to the first conductive pressing block 40. Similarly, the second conductive compact 50 can also be electrically connected to the discharge cabinet through a wire, which is not described herein. In addition, it is understood that the first conductive compact 40 and the second conductive compact 50 may also be electrically connected to the discharge chamber by other methods, and the embodiment is not limited herein.
It should be noted that the battery discharging apparatus in the present embodiment may be disposed inside the battery discharging apparatus as a part of the battery discharging apparatus, and in this case, the bottom plate of the battery discharging apparatus may be used as the platform 20, that is, the structure of the platform 20 may be omitted. Alternatively, the battery pack discharge device may be an independent external device, and in this case, the first conductive compact 40 and the second conductive compact 50 may be connected to the discharge circuit, respectively. In addition, when the battery pack discharging device is an independent external device, the structure of the platform 20 may be omitted, and the conductive module and other structures may be directly placed on the ground, which is not limited herein.
The platform 20 is provided with two first guide rails 60, each of the first guide rails 60 can extend along a first direction, the second support frame 32 can be mounted on the first guide rail 60 through a first sliding block 70, and the first sliding block 70 can slide along the first direction relative to the first guide rail 60. It can also be understood that one side of the first slider 70 facing the second support frame 32 may be fixedly connected to the second support frame 32, and one side of the first slider 70 facing the first guide rail 60 may be slidably connected to and matched with the first guide rail 60, so that, under the sliding action of the first slider 70, the second support frame 32 may drive the first conductive pressing block 40 and the second conductive pressing block 50 to move along the first direction, so that the first conductive pressing block 40 and the second conductive pressing block 50 may move to above different battery cells 101.
In this embodiment, a motor may be used to drive the first slide to slide on the first guide rail 60, so as to drive the first conductive pressing block 40 and the second conductive pressing block 50 to move along the first direction. In addition, a controller may be further provided, and the controller is used to control the sliding stroke of the motor for driving the first slider 70 each time, so that the first conductive pressing block 40 and the second conductive pressing block 50 can be aligned with the battery core 101 after each movement.
Of course, since the friction coefficient between the first slider 70 and the first guide rail 60 is small, the first slider 70 may be manually pushed to slide. During specific implementation, a limiting structure corresponding to the battery cell 101 may be disposed on the first guide rail 60, and when the first slider 70 is pushed to a corresponding position, the limiting structure may limit the first slider 70, so as to prevent the first slider 70 from continuously sliding. For example, the limiting structure may be a limiting block that is lifted relative to the first guide rail 60, and when the first slider 70 slides, the limiting block may be lifted to be flush with the surface of the first guide rail 60, so that the movement of the first slider 70 is not affected. When the first slider 70 slides to the set position, the stopper can rise to a position for stopping the first slider 70, thereby preventing the first slider 70 from sliding.
It should be noted that the motor driving or the manual pushing are examples of the sliding of the first slider 70, and in practical applications, other manners may also be used to drive the first slider 70 to slide.
As shown in fig. 3, the first support frame 31 is provided with a second guide rail 80, and the second guide rail 80 may extend along a second direction, which may be considered as the height direction of the battery pack 10, and the second direction may be perpendicular to the first direction, or may be understood as the second direction being perpendicular to the platform 20. The first conductive pressing block 40 can be mounted on the second guide rail 80 through the second sliding block 90, and the second sliding block 90 can slide along the second direction relative to the second guide rail 80, and it can also be understood that one side of the second sliding block 90 facing the first conductive pressing block 40 can be fixedly connected with the first conductive pressing block 40, and one side of the second sliding block 90 facing the second guide rail 80 can be slidably connected with the second guide rail 80. Thus, when the second sliding block 90 slides, the first conductive pressing block 40 is driven to move along the second direction, i.e. to move close to the battery pack 10 or move away from the battery pack 10. Likewise, the second conductive compact 50 may be connected to the second rail 80 by the same structure, which will not be described herein.
As described above, the first conductive compact 40 and the second conductive compact 50 are both electrically connected to the discharge tank, the first conductive compact 40 may be aligned with the positive electrode 1011 of the electric core 101, and the second conductive compact 50 may be aligned with the negative electrode 1012 of the electric core 101. When the first conductive compact 40 and the second conductive compact 50 move towards the battery pack 10 until the first conductive compact 40 and the second conductive compact 50 contact the battery pack 10, the first conductive compact 40 can be electrically connected with the positive pole 1011 of the battery cell 101, and the second conductive compact 50 is electrically connected with the negative pole 1012 of the battery cell 101, so that under the conducting action of the first conductive compact 40 and the second conductive compact 50, the discharge cabinet is electrically connected with the battery cell 101, and thus the battery cell 101 can be discharged. In the process, the discharge cabinet does not need to be manually connected with the positive electrode 1012 and the negative electrode 1012 of the battery core 101, so that an operator can be prevented from directly contacting with charged articles, and the operation safety is improved.
In this embodiment, with reference to fig. 2 and 3, a locking buckle 110 may be further provided to drive the second slider 90 to slide. In specific implementation, one side of the second rail 80 away from the platform 20 may be connected to a connection plate 100 parallel to the platform 20, the connection plate 100 is provided with a through hole, the locking buckle 110 may include a buckling portion 111 and a connection portion 112, one end of the connection portion 112 may be connected to the second slider 90, and the other end passes through the through hole and then is connected to the buckling portion 111. The locking portion 111 can rotate relative to the connecting portion 112, and when the locking portion 111 rotates to the first station, the locking portion 111 can be also considered as a state parallel to the platform 20 in fig. 3, so that the second slider 90 cannot slide along the second direction relative to the second rail 80. When the locking portion 111 rotates to the second position, which can be understood as a state perpendicular to the platform 20, the second slider 90 can slide along the second direction relative to the second rail 80. It can be understood that the structure of the locking buckle 110 can be manually operated to realize the up-and-down movement of the first conductive pressing block 40 and the second conductive pressing block 50, which is time-saving and labor-saving.
Of course, the second sliding block 90 can be driven by a motor to slide relative to the second guiding rail 80 in this embodiment, which is not limited herein. In addition, the locking buckle 110 may also be in other structural forms, and the embodiment is not limited herein.
An elastic component 120 can be further arranged between the first conductive pressing block 40 and the second sliding block 90, and the elastic component 120 can be used for generating certain buffering force when the first conductive pressing block 40 is in contact with the battery core 101, so that the surface of the first conductive pressing block 40 is prevented from being damaged in the repeated collision contact process with the battery core 101, and subsequent discharging is further influenced. Similarly, an elastic member 120 may be disposed between the second conductive pressing block 50 and the second slider 90, which will not be described herein.
With continued reference to fig. 2, the first support frame 31 is further provided with third guide rails 130 extending along a third direction, each second guide rail 80 can be mounted on the third guide rail 130 through a third slider 140, and the third slider 140 can slide relative to the third guide rail 130, where the third direction is perpendicular to the first direction and perpendicular to the second direction. Under the action of the third slider 140, the second guide rail 80 can move along the third direction, and drives the first conductive pressing block 40 and the second conductive pressing block 50 to move along the third direction. Because the sizes of the battery packs 10 of different models are different, by providing the third slider 140 and the third guide rail 130, the distance between the first conductive pressing block 40 and the second conductive pressing block 50 can be adjusted, so that it is ensured that the first conductive pressing block 40 and the second conductive pressing block 50 can always face the positive electrode 1011 and the negative electrode 1012 of the electric core 101.
The third slider 140 can be driven by a motor or manually to slide, and the specific implementation manner thereof can refer to the structure of the first slider 70, which is not described herein.
In addition, the platform 20 may further include a positioning component 150 for positioning the battery pack 10, and after the battery pack 10 is placed on the platform 20, the positioning component may fix the battery pack 10, so as to prevent the first conductive pressing block 40 and the second conductive pressing block 50 from deviating during movement and when being electrically connected to the positive electrode 1011 and the negative electrode 1012 of the electric core 101, which may result in the electric core 101 being unable to be electrically connected to the discharge cabinet.
In a specific implementation, the positioning component 150 may include a first positioning block 151 and a second positioning block 152, the first positioning block 151 may extend along a first direction, and the second positioning block 152 may extend along a third direction.
