Description

TECHNICAL FIELD

[0001] The present application relates to battery replacement technology, and particularly provides a battery compartment preventing jamming, a battery rack and a battery replacement station. BACKGROUND

[0002] At present, when a full battery is discharged from a battery compartment and a feeding battery is discharged into the battery compartment in the battery replacement process of a battery replacement station, the batteries are transported by a rubber-coated chain, and the battery compartment is guided and limited by a guide strip fixed on the frame of the battery compartment by bolts.

[0003] However, when the battery is not flat or slightly tilted, the battery still may be jammed in the battery compartment, which prevents the battery replacement from being continued. In addition, when the battery is in thermal runaway, the battery in thermal runaway needs to be transferred from the battery compartment to a battery elevator or a parking platform according to the fire-fighting strategy to avoid the battery in thermal runaway igniting other batteries in the battery compartment. At this time, if the battery is jammed in the battery compartment, the battery in thermal runaway cannot be transferred from the battery compartment, which may ignite other batteries in the battery compartment, causing more serious loss and safety accidents.

[0004] Correspondingly, a new battery compartment preventing jamming is needed. SUMMARY

DETAILED DESCRIPTION

[0075] The preferred embodiments of the present application will be described below with reference to the accompanying drawings, in which:

[0076] It should be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected, it can be mechanically connected, or electrically connected, it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. In addition, the terms "front", "back" and the like indicate the orientation or position relationship for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, "a plurality of" in the present application means at least two.

[0077] As shown in Figures 1-5 To solve the problem that the battery is easy to be stuck in the battery compartment when the battery enters or exits the battery compartment, the present application provides a battery compartment to prevent the battery from being stuck, which comprises a frame 1, a plurality of guiding devices 2 and a plurality of positioning devices 3. The frame 1 is surrounded to form a space allowing the battery to enter or exit, and the frame 1 is connected with the guiding device 2 and the positioning device 3 on both sides along the width direction of the battery entering or exiting, wherein the guiding device 2 has a floating end which is floatingly arranged along the width direction, and the positioning device 3 has an extension end which can extend and retract along the width direction, and the extension end is arranged to be flush with the floating end or located in front of the floating end in the extended state, and located behind the floating end in the retracted state. In this way, when the battery with insufficient flatness or slight skew enters the battery compartment, the battery can be straightened through the contact between the floating end of the guiding device 2 and the battery, thereby avoiding the problem of being stuck. When the battery is placed in the battery compartment and in place, the extension end of the positioning device 3 straightens the battery, thereby ensuring the accurate position of the battery in the battery compartment and avoiding the wear of the water and electricity plug caused by the skew of the battery during the contact between the battery and the water and electricity plug.

[0078] It should be noted that the width direction of the battery entering or exiting here should be the direction perpendicular to the direction of the battery entering or exiting in the horizontal plane (the left-right direction of the paper, and the width direction of the battery entering or exiting is the up-down direction of the paper), which is equivalent to that the guiding device 2 and the positioning device 3 are located on both sides of the battery after the battery enters or exits the battery compartment, which facilitates the guiding of the battery by the guiding device 2, and also facilitates the positioning of the battery by the positioning device 3. Figure 1 Referring to

[0079] , the frame 1 comprises a bottom support 11 for supporting the battery and a mounting beam 12 located on the upper side of the bottom support 11 near the two ends, and the battery enters or exits between the two mounting beams 12, and the mounting beam 12 is used to mount the guiding device 2 and the positioning device 3. Figure 1

[0080] ​It should be noted that the specific structure of the bottom support 11 can be any shape that can achieve the above functions, such as a support plate, as long as it can pass through the battery. The mounting beam 12 in this embodiment is used to mount the guide device 2 and the positioning device 3, and can be an I-shaped steel, an angle steel, a square tube, or any other structure that can achieve the above functions.

[0081] Referring to Figure 2 In a preferred embodiment of the present application, the guide device 2 includes elastic members 21 and a guide strip 22, and the two ends of the elastic members 21 are connected to the mounting beam 12 and the guide strip 22, respectively. In this way, when the battery entering the battery compartment presses the guide strip 22, the skewed battery is straightened by the elastic force of the elastic members 21. Preferably, the elastic members 21 are compression springs, and the number of elastic members 21 is two. The two elastic members 21 are arranged along the length direction of the guide strip 22, so that the guide strip 22 is more stable and avoids rotation and deviation in the non-floating direction relative to the elastic members 21. The end surface of the guide strip 22 away from the elastic members 21 is connected to freely rotating guide wheels 23, and the number of guide wheels 23 is two, which are arranged along the length direction of the guide strip 22. In this way, the guide wheels 23 form rolling friction between the battery and the guide strip 22 when the battery enters or exits the battery compartment, avoiding wear on the edges of the battery, and the two guide wheels 23 can fully contact the battery. The guide wheel 23 includes a wheel body and a rubber wrapping, the wheel body is connected to the guide strip 22, and the rubber wrapping is wrapped around the outer periphery of the wheel body. In this way, the wheel body wrapped with rubber contacts the battery, further reducing wear on the edges of the battery.

[0082] It should be noted that the elastic members 21 can also be other structures that can achieve the floating of the guide strip 22 and can straighten the battery, and the elastic members 21 are preferably compression springs, and the number of elastic members 21 can achieve the floating of the guide strip 22, which can be one, two, or three, and the optimal choice is two, and the number of guide wheels 23 can achieve the guiding of the battery, which can be one, two, or three, and the optimal choice is two. The setting of the guide wheel 23 is not necessary, and the person skilled in the art can choose whether to set the guide wheel 23 based on the application scenario, and the specific structure of the guide wheel 23, such as whether to be rubber-coated, and of course, it can also not be set, and the guide strip 22 can be directly contacted with the battery.

[0083] Continuing to refer to Figure 2In a preferred embodiment of the present application, the positioning device 3 comprises a telescopic mechanism 31 and a pressing head 32, the telescopic mechanism 31 is connected with the mounting beam 12, and the telescopic mechanism 31 is connected with the pressing head 32 at one end. In this way, the telescopic mechanism 31 is extended at one end, so that the pressing head 32 can press the battery, thereby supporting the battery and achieving accurate positioning of the battery in the battery compartment. Preferably, the telescopic mechanism 31 is an electric push rod, and is fixed to the mounting beam 12 by bolts, and the telescopic mechanisms 31 on the same mounting beam 12 are connected to the same driving circuit 6. In this way, the telescopic mechanisms 31 on the same side are driven by the same driving circuit 6, which can improve the synchronization of the telescopic mechanisms 31 on the same side and ensure the positioning accuracy of the battery.

[0084] Another possible implementation of the telescopic mechanism 31 is that the telescopic mechanism 31 can also be driven by a motor, a gear and a rack. The motor drives the gear to rotate, and the gear cooperates with the rack to move the rack. The pressing head 32 is connected to one end of the rack, thereby achieving the movement of the pressing head 32. Alternatively, a combination of a motor, a nut and a screw can also be used. The motor drives the nut to rotate, and the nut and the screw are threadedly connected. The rotation of the nut drives the movement of the screw. The pressing head 32 is fixed to one end of the screw, thereby achieving the movement of the pressing head 32.

[0085] It should be noted that the telescopic mechanism 31 is used to drive the pressing head 32 to press and support the battery. As long as the structure can achieve the above functions, it belongs to the protection scope of the present application. The telescopic mechanism 31 can be a pneumatic cylinder, an oil cylinder, an electric push rod or other structures that can achieve the above functions. The optimal choice is an electric push rod. It is not necessary to connect the telescopic mechanisms 31 on the same mounting beam 12 to the same driving circuit 6. Those skilled in the art can choose whether to connect the telescopic mechanisms 31 to the same driving circuit 6 based on the basic application scenario. They can also choose to connect the telescopic mechanisms 31 to different driving circuits 6. The specific connection mode of the driving circuit 6 is a prior art, which will not be described here.

[0086] Referring to FIG. 1, Figure 1 and 5In a preferred embodiment of the present application, a to-position sensing device 4 is further included, which is connected with the bottom support 11 and is arranged to send a feedback signal to the outside after the battery is in position. In this way, the to-position sensing device 4 can detect whether the battery is placed in position in the battery compartment, and when the battery is placed in position, the to-position sensing device 4 sends a signal to the outside that the battery has been placed in position. Specifically, the to-position sensing device 4 includes a blocking block 41 connected with the bottom support 11 and a detection sensor 42 with a detection end located in the blocking block 41. Preferably, the blocking block 41 is provided with a mounting hole, the detection sensor 42 is inserted into the mounting hole, and the end of the detection sensor 42 is located at the rear side of the hole of the mounting hole. In this way, the blocking block 41 can protect the detection sensor 42 from being damaged by the battery, and at the same time, the end of the detection sensor 42 is located at the rear side of the hole of the mounting hole, so the blocking block 41 can effectively protect the detection sensor 42.

[0087] It should be noted that the blocking block 41 is used to block the battery, and the shape of the blocking block 41 can be any shape as long as it can block the battery. At the same time, one end of the detection sensor 42 is located in the mounting hole, and the mounting hole can be any shape as long as it can install the detection sensor 42. In addition, the to-position sensing device 4 is not necessarily provided, and those skilled in the art can choose whether to provide the to-position sensing device 4 based on the specific application scenario and the specific structure.

[0088] Referring to FIG. 1, Figure 5 In a preferred embodiment of the present application, a shock buffering device 7 is further included, which is connected with the bottom support 11 and the detection sensor 42 is connected with the shock buffering device 7. In this way, even if the detection sensor 42 is touched by foreign matter on the battery, the detection sensor 42 can be buffered by the shock buffering device 7, thereby further avoiding damage to the detection sensor 42. Further, the shock buffering device 7 includes a buffering support 72 connected with the bottom support 11 and a buffering piece 71 floatingly arranged in the buffering support 72, and the detection sensor 42 is connected with the buffering piece 71. In this way, when the detection sensor 42 is impacted, the floating arrangement of the buffering piece 71 and the buffering support 72 can avoid damage to the detection sensor 42. Preferably, the buffering piece 71 adopts a clamp, and the clamp is connected with the buffering support 72 through a spring 73.

[0089] It should be noted that the spring 73 here can be replaced by an elastic rope, or other materials that can achieve floating connection between the hoop and the buffer support 72. The role of the hoop here is to connect the spring 73 and the detection sensor 42, and a rubber ring or other structural member can also be used as long as it can achieve the connection of the spring and the detection sensor 42. At the same time, the impact buffering device 7 is not necessary to be set, and the person skilled in the art can select whether to set the impact buffering device 7 and the specific structure of the impact buffering device 7 based on the specific application scene. Of course, the impact buffering device 7 can not be set, and the detection sensor 42 is only connected with the mounting hole.

[0090] Another possible embodiment of the impact buffering device 7 is that the impact buffering device 7 includes a buffer support 72 and a buffer filler, the buffer support 72 is formed with a cavity, and the non-detection end of the detection sensor 42 is located in the cavity. The buffer filler is located between the inner wall of the buffer support 72 and the outer wall of the detection sensor 42. When the detection sensor 42 is impacted, the buffer filler and the buffer support 72 are used to avoid damage to the detection sensor 42. The buffer filler here can be sponge or rubber, as long as it can deform during the shaking of the detection sensor 42 and can rebound.

[0091] Referring back to Figure 1 In a preferred embodiment of the present application, a conveying device is further included, which is arranged on the bottom support 11. The conveying device includes a conveying motor and a rubber-coated chain 5, and the conveying motor is connected with the rubber-coated chain 5. It should be noted that the specific structure of the conveying device can be selected by the person skilled in the art based on the application scene, and it can also be a stacker or other structure that can place the battery into the battery compartment.

[0092] Continuing to refer to Figure 1 In a preferred embodiment of the present application, the guide device 2 and the positioning device 3 are arranged in sequence along the direction of the battery in and out. In this way, the guide device 2 is uniformly distributed in the direction of the battery in and out, which facilitates the guiding of the battery, and the positioning device 3 is uniformly distributed in the direction of the battery in and out, which facilitates the positioning of the battery.

[0093] It should be noted that the sequential arrangement can be that one positioning device 3 is arranged between two guide devices 2 of the same mounting beam 12, or two positioning devices 3 are arranged between two guide devices 2, or other arrangements that can be thought of by those skilled in the art, and the optimal choice is that one positioning device 3 is arranged between every two adjacent guide devices 2 of the same mounting beam 12, and the guide strip 22 located at the entrance of the battery compartment has a guide slope to facilitate the battery to enter the battery compartment. It should be further noted that the sequential arrangement refers to that the positioning device 3 and the guide device 2 can be arranged staggered in the length direction of the mounting beam 12 and in the width direction of the mounting beam 12, or the positioning device 3 and the guide device 2 are located on the same plane, and the optimal choice is that the positioning device 3 and the guide device 2 are located on the same plane.

[0094] The following will be described in combination with Figures 1 to 5 A possible use of the present application is described. When placing the battery into the battery compartment, first, the conveying motor is started, the conveying motor drives the rubber-coated chain 5 to move, the rubber-coated chain 5 drives the battery to move into the battery compartment, in the case that the battery normally enters the battery compartment without tilting, the battery contacts the guide wheel 23, the battery gradually moves into the battery compartment, and the jacking head 32 of the positioning device 3 is flush with the upper surface of the guide strip 22 (as shown in Figure 3 When the battery reaches the designated position in the battery compartment, the detection sensor 42 detects that the battery has been positioned, at this time, the detection sensor 42 sends a signal to stop the rotation of the conveying motor. Subsequently, the extension end of the telescopic mechanism 31 is extended, driving the jacking head 32 to move away from the telescopic mechanism 31 to the position as shown in Figure 4 , completing the accurate positioning of the battery.
