Description

Technical Field

[0001] The utility model relates to the field of battery replacement, and in particular to a channel opening and closing device for battery replacement equipment to enter and exit, and a battery replacement station. Background Art

[0002] Charging and swapping stations for replacing or charging batteries in electric vehicles are widely used. In current charging and swapping stations, battery packs are replaced mainly by moving the battery swapping equipment back and forth between the electric vehicle and the battery compartment. However, due to the presence of the battery swapping equipment, an inlet and outlet are required between the battery compartment and the outside world, which also causes the battery compartment to be connected to the outside world. External debris, animals, and insects may enter through the inlet and outlet, causing damage to the inside of the battery compartment. At the same time, the temperature control in the battery compartment is not easy to maintain.

[0003] In existing battery swap stations, the opening and closing device of the access passage of the battery swap equipment drives the transmission mechanism to pull the door body through the drive mechanism. Since the transmission mechanism usually uses a sprocket and chain to connect the door body and the drive mechanism, during transportation, the opening and closing device of the passage is not always set vertically and stable, and it is very likely to tip over, cut obliquely or shake, causing the chain to fall off the sprocket, causing structural damage or reducing assembly efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defect in the prior art that the channel opening and closing device is not always arranged vertically and stably during transportation, and it is very likely to tip over, cut obliquely or shake, causing the chain to fall off the sprocket, causing structural damage or reducing assembly efficiency. A channel opening and closing device for the entry and exit of battery exchange equipment and a battery exchange station are provided.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] A device for opening and closing a passageway for entering and exiting a battery exchange device comprises a door frame, a door body, a driving mechanism, and a transmission mechanism. The door body can be raised and lowered and moved within the door frame. The door frame is arranged at a battery exchange station. The transmission mechanism is connected to the door body. The driving mechanism drives the transmission mechanism to move, and the door body is driven to be raised and lowered by the transmission mechanism. The transmission mechanism at least comprises a chain and a first sprocket arranged on the power output end of the driving mechanism. The chain passes around the first sprocket and is connected to the door body. It also comprises a transport fixing mechanism, one end of which is fixed to the door frame, and the other end of which is fixed to the door body, so as to fix the door frame and the door body.

[0007] In the present scheme, the above-mentioned structure is adopted, and the door frame and the door body can be fixed by the transport positioning mechanism to prevent the door body from moving relative to the door frame.

[0014] Preferably, the first connecting portion comprises a waist hole, the door frame is provided with a threaded hole corresponding to the waist hole, and the first connecting portion is connected to the door frame by bolts.

[0015] In this solution, the above structure is adopted, and the first connecting part utilizes the threaded holes pre-opened on the door frame to be bolted to the door frame, without the need to set up other additional connecting mechanisms. At the same time, a detachable connection can also be achieved, which is convenient for the reuse of the transportation fixing mechanism.

[0016] Preferably, the second connecting portion has a receiving groove matching the thickness of the door body, the opening of the receiving groove faces downward of the door body, and the top end of the door body extends into the receiving groove to achieve a snap connection between the second connecting portion and the top surface of the door body.

[0017] In the present solution, the above-mentioned structure is adopted, and the second connecting part and the door body are connected by a snap-fit ​​connection, which can realize the limiting effect on the front and rear directions of the door body. At the same time, the snap-fit ​​connection device is detachable. During assembly, it is only necessary to first clamp the second connecting part on the upper end of the door body, and then fix the first connecting part and the door frame bolts. Both assembly and disassembly are relatively convenient.

[0018] Preferably, the second connecting portion includes a top plate connected to the top surface of the door body and extended side plates extending from both ends of the top plate along the inner and outer surfaces of the door body, and the two extended side plates and the top plate jointly define the accommodating groove.

[0054] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0055] This embodiment provides a battery swap station, which includes at least one battery compartment and an operating compartment. The battery compartment is used to store and charge batteries, and the operating compartment is used for electric vehicles to drive in and replace batteries. The battery swap station moves between the battery compartment and the operating compartment through the battery swap equipment and completes the transportation, installation, disassembly, and placement of batteries. Due to the battery working environment requirements and safety requirements, the battery compartment needs to be equipped with a channel opening and closing device to form an openable and closable channel opening. The channel opening and closing device can close the channel opening and open the channel opening when personnel or battery swap equipment enter and exit the battery swap station.

[0056] like Figure 1As shown, the present embodiment provides a passage opening and closing device for the entry and exit of battery exchange equipment, including a door frame 10, a door body 20, a driving mechanism 50, and a transmission mechanism 40. The door body 20 can be raised and lowered and moved in the door frame 10. The door frame 10 is arranged at the battery exchange station. The transmission mechanism 40 is connected to the door body 20. The driving mechanism 50 drives the transmission mechanism 40 to move. The door body 20 is driven to rise and fall through the transmission mechanism 40. The transmission mechanism 40 at least includes a chain 41 and a first sprocket 42 provided on the power output end 52 of the driving mechanism 50. The chain 41 bypasses the first sprocket 42 and is connected to the door body 20. It also includes a transport fixing mechanism 60. One end of the transport fixing mechanism 60 is fixed to the door frame 10, and the other end of the transport fixing mechanism 60 is fixed to the door body 20, so as to fix the door frame 10 and the door body 20. Specifically, the passage opening and closing device of this embodiment is a lifting type, and the door frame 10 is arranged on one side of the battery compartment. The door frame 10 is provided with a transmission mechanism 40 for driving the door body 20 to move up and down, and a driving mechanism 50 for driving the transmission mechanism 40 to move. The transmission mechanism 40 and the driving mechanism 50 are both arranged above the door body 20, and are located above the highest point of the movement position of the door body 20. The transmission mechanism 40 includes a chain 41 and at least one first sprocket 42, and the two ends of the chain 41 are respectively connected to the driving mechanism 50 and the door body 20, and the first sprocket 42 is bypassed to turn, so that the driving mechanism 50 can move in the horizontal direction to drive the door body 20 to rise and fall in the vertical direction. In addition to the first sprocket 42, the transmission mechanism 40 can also be provided with multiple sets of sprockets to guide and bend the chain 41, so that the chain 41 can be arranged in an appropriate position, does not occupy the space of other components, and is also convenient for arranging the driving mechanism 50 in an appropriate position according to needs. Since the transmission mechanism 40 includes a plurality of sprockets and chains 41, in the assembled state, the door body 20 can tighten the chain 41 by its own weight so that the chain 41 is fixed on the sprocket. However, when the passage opening and closing device needs to be transported, since the passage opening and closing device is not always arranged vertically and stably during transportation, it is likely to tip over, be cut obliquely or shake, so that the weight of the door body 20 cannot restrain the chain 41 to make it tight, which may cause the chain 41 to lose its restraining force and become loose, and then fall off the sprocket. This may cause structural damage or reduce assembly efficiency. Therefore, before transportation, a transportation positioning mechanism will be assembled on the door body 20, one end of which is connected to the door body 20, and the other end is connected to the door frame 10, so that the door body 20 and the door frame 10 are relatively fixed. Through the transport positioning mechanism, the door frame 10 and the door body 20 can be fixed to prevent the door body 20 from moving relative to the door frame 10. During transportation, by installing the transport fixing mechanism 60 on the opening and closing device of the passageway where the battery exchange equipment enters and exits, it is possible to avoid movement of the door body 20 relative to the door frame 10 due to bumps, tilts and other factors during transportation, thereby avoiding damage to the opening and closing device of the passageway and also avoiding the situation where the chain 41 falls off the first sprocket 42 due to loss of vertical gravity constraint or bumps.

[0057] like Figure 2 As shown, the transport fixing mechanism 60 is fixedly connected to the top surface of the door body 20. Specifically, the door frame 10 includes two longitudinal beams 11 and a cross beam 12 connecting the two longitudinal beams 11 by the top surface. The door body 20 is connected to the longitudinal beams 11 of the door frame 10, and the movement direction of the door body 20 is consistent with the extension direction of the longitudinal beams 11. The transport fixing mechanism 60 is clamped at the top surface of the movement direction of the door body 20 and fixed on the longitudinal beams 11, blocking the upward movement of the door body 20 on the movement path of the door body 20. It can further enhance the limiting effect of the longitudinal lifting movement of the door body 20, and the fixing effect is better.

[0058] Preferably, if Figure 2 As shown, the transport fixing mechanism 60 is arranged at the top corner of the door body 20. The arrangement position is suspended at the end corner of the door body 20, and the distance between this position and the longitudinal beam 11 and the top surface of the door body 20 is the shortest, so that the transport fixing mechanism 60 can simply connect the door frame 10 and the top surface of the door body 20, reduce its structural complexity, and thus improve the space utilization and the structural strength of the transport fixing mechanism 60.

[0059] In other embodiments, the transport fixing mechanism 60 may also be arranged at other positions, such as the side surface or bottom surface of the door body 20, and its connection with the door frame 10 is not limited to the side of the longitudinal beam 11 facing the door body 20, and may also be arranged on the longitudinal beam 11 or other structures, such as one end of the longitudinal beam 12 and the other end of the longitudinal beam 12 in the vertical direction. In general, the transport fixing mechanism 60 only needs to ensure that the door body 20 and the door frame 10 are relatively fixed to achieve its function, but the arrangement position structure in this embodiment is the simplest and most compact and has a good fixing effect.

[0060] In this embodiment, the specific structure of the transport fixing mechanism 60 is as follows: Figure 3 , Figure 4 As shown, it includes two first connecting parts 61 and second connecting parts 62 set at an angle, the first connecting part 61 and the second connecting part 62 are L-shaped, the first connecting part 61 is connected to the door frame 10, and the second connecting part 62 is connected to the top surface of the door body 20. The L-shaped structure has a strong torsion resistance, which can further enhance the fixing effect of the door frame 10 and the door body 20, and enhance the limiting effect of the lifting and lowering movement of the door body 20. In addition, the L-shaped structure also corresponds to the triangular area shape of the end angle position of the door body 20 and the longitudinal beam 11, so that the two sides of the L-shape can fit the top surface of the door body 20 and the side of the longitudinal beam 11. Preferably, the inner sides of the first connecting part 61 and the second connecting part 62 can also be connected to form a triangular structure to obtain higher support strength and better limiting effect.

[0061] In this embodiment, the first connection part 61 and the second connection part 62 are integrally formed. The use of an integral molding process can increase the strength of the first connection part 61 and the second connection part 62. In other embodiments, the first connection part 61 and the second connection part 62 can also be processed by a method of manufacturing separately and then connecting and assembling.

[0062] like Figure 3 , Figure 4 As shown, the first connection part 61 includes a waist hole 611, and the door frame 10 is provided with a threaded hole 111 corresponding to the waist hole 611, and the first connection part 61 is connected to the door frame 10 by bolts. The second connection part 62 has a receiving groove 623 that matches the thickness of the door body, and the opening of the receiving groove 623 faces the bottom of the door body 20. The top of the door body 20 extends into the receiving groove 623 to realize the clamping connection between the second connection part 62 and the top surface of the door body 20. The first connection part 61 uses the threaded hole 111 pre-opened on the door frame 10 to be bolted to the door frame 10, without the need to set up other additional connection mechanisms, and can also achieve detachable connection, which is convenient for the repeated use of the transportation fixing mechanism 60. The second connecting part 62 is connected to the door body 20 by a snap-fit ​​connection, which can realize the limiting effect on the front and rear directions of the door body 20. At the same time, the snap-fit ​​connection is detachable. During assembly, it is only necessary to first snap the second connecting part 62 onto the upper end of the door body 20, and then fix the first connecting part 61 to the door frame 10 with bolts. Both assembly and disassembly are relatively convenient.

[0063] Specifically, Figure 3 , Figure 4 As shown, the second connecting portion 62 includes a top plate 621 connected to the top surface of the door body 20 and an extended side plate 622 extending from both ends of the top plate 621 along the inner and outer surfaces of the door body 20, and the two extended side plates 622 and the top plate 621 jointly define a receiving groove 623. The second connecting portion 62 is in an inverted U shape, and is clamped on the door body 20 through the receiving groove 623. The two side plates 622 are respectively abutted against the front and back surfaces of the door body 20, and the fixing effect is good. In other embodiments, the second connecting portion 62 can also be provided with only one top plate 621 to support the door body 20 in the vertical direction. In the horizontal direction, the door body 20 has been relatively stably limited on the door frame 10 by the guide mechanism 30 and the like.

[0064] like Figure 5As shown, the guide mechanism 30 includes a slider 32 and a slide rail 31. The door body 20 and the door frame 10 are lifted and lowered relative to each other through the slider 32 and the slide rail 31. The slider 32 is slidably connected to the slide rail 31. One of the slide rail 31 and the slider 32 is arranged on the door frame 10 through a threaded hole 111. The guide mechanism 30 of this embodiment is arranged between the door body 20 and the longitudinal beam 11 of the door frame 10. The longitudinal beam 11 is provided with the slide rail 31 on the side facing the door body 20. The slider 32 is connected to the door body 20 and is clamped in the slide rail 31. In other embodiments, the arrangement positions of the slide rail 31 and the slider 32 can also be exchanged, with the longitudinal beam 11 protruding outward, and the door body 20 is provided with a groove structure clamped on the longitudinal beam 11 to slide. The slide rail 31 is fixed to the longitudinal beam 11 through a threaded hole 111 pre-opened on the longitudinal beam 11. The threaded hole 111 is the same as the threaded hole 111 for connecting the first connecting part 61 of the passage opening and closing device. The first connecting part 61 of the guide mechanism 30 and the transport fixing mechanism 60 are both fixed through the same threaded hole 111, further improving space utilization.
