Description

Technical Field

[0001] The present invention relates to the field of battery swapping, and particularly to a channel opening and closing device for the entry and exit of a battery swapping device and a battery swapping station. Background Art

[0002] Charging and swapping stations for replacing batteries or charging batteries of electric vehicles are widely used. In current charging and swapping stations, the replacement of battery packs is mainly achieved by the back-and-forth movement of a battery swapping device between an electric vehicle and a battery compartment. However, due to the presence of the battery swapping device, an access channel opening is required between the battery compartment and the outside world, which also leads to the connection between the battery compartment and the outside world. External sundries, animals, and insects may enter through the access channel opening, resulting in damage to the interior of the battery compartment. At the same time, it is not easy to maintain the temperature control inside the battery compartment.

[0003] In existing battery swapping stations, the opening and closing device of the access channel opening of the battery swapping device drives a transmission mechanism to pull a door body through a driving mechanism. Since the transmission mechanism usually uses a sprocket and a chain to connect the door body and the driving mechanism, during transportation, the channel opening and closing device is not always vertically arranged and stable. It is very likely to be tilted, skewed, or jolted, resulting in the chain coming off the sprocket. This causes structural damage or reduces the assembly efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect in the prior art that during transportation, the channel opening and closing device is not always vertically arranged and stable, and it is very likely to be tilted, skewed, or jolted, resulting in the chain coming off the sprocket, causing structural damage or reducing the assembly efficiency. The present invention provides a channel opening and closing device for the entry and exit of a battery swapping device and a battery swapping station.

[0005] The present invention solves the above technical problem through the following technical solutions:

[0006] A channel opening and closing device for the entry and exit of a battery swapping device, comprising a door frame, a door body, a driving mechanism, and a transmission mechanism. The door body is movable up and down within the door frame. The door frame is arranged in a battery swapping station. The transmission mechanism is connected to the door body. The driving mechanism drives the transmission mechanism to move, and drives the door body to move up and down through the transmission mechanism. The transmission mechanism at least includes a chain and a first sprocket arranged on the power output end of the driving mechanism. The chain bypasses the first sprocket and is connected to the door body. It further includes a transportation fixing mechanism. One end of the transportation fixing mechanism is fixed to the door frame, and the other end of the transportation fixing mechanism is fixed to the door body to fix the door frame and the door body.

[0007] In this solution, adopting the above structure, through the transportation positioning mechanism, the door frame and the door body can be fixed to prevent the door body from moving relative to the door frame. During transportation, by installing the transportation fixing mechanism on the opening and closing device of the channel through which the battery swapping device enters and exits, it can avoid the movement of the door body relative to the door frame caused by factors such as bumps and tilts during transportation, prevent damage to the opening and closing device of the channel, and also avoid the situation where the chain disengages from the first sprocket due to the loss of vertical gravity constraint or bumps.

[0008] Preferably, the transportation fixing mechanism is fixedly connected to the top surface of the door body.

[0009] In this solution, adopting the above structure, being arranged on the top surface of the door body and limiting the door body in the moving direction of the door body can further enhance the limiting effect on the longitudinal lifting movement of the door body, and the fixing effect is better.

[0010] Preferably, the transportation fixing mechanism is arranged at the top end corner of the door body.

[0011] In this solution, adopting the above structure, being suspended at the end corner of the door body, this position has the closest distance to the door frame and the top surface of the door body, enabling the transportation fixing mechanism to simply connect the door frame and the top surface of the door body, reducing its structural complexity, and thus enhancing the space utilization rate and the structural strength of the transportation fixing mechanism.

[0012] Preferably, the transportation fixing mechanism includes two first connecting parts and a second connecting part arranged at an angle. The first connecting part and the second connecting part are in an L shape. The first connecting part connects the door frame, and the second connecting part connects the top surface of the door body.

[0013] In this solution, adopting the above structure, the L-shaped structure has strong anti-torsion ability, can further strengthen the fixing effect between the door frame and the door body, and enhance the limiting effect on the lifting movement of the door body.

[0014] Preferably, the first connecting part includes a waist-shaped hole, and a threaded hole corresponding to the waist-shaped hole is provided on the door frame. The first connecting part is connected to the door frame by bolts.

[0015] In this solution, adopting the above structure, the first connecting part uses the pre-opened threaded hole on the door frame to connect to the door frame by bolts, without the need to additionally set other connecting mechanisms, and at the same time can also achieve detachable connection, facilitating the reuse of the transportation fixing mechanism.

[0016] Preferably, the second connecting part 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 the snap connection between the second connecting part and the top surface of the door body.

[0017] In this solution, with the above structure, the second connecting part and the door body are connected by snap connection, which can realize the limit function in the front and back directions of the door body. At the same time, the snap connection is detachable. During assembly, it only needs to first snap the second connecting part on the upper end of the door body, and then bolt the first connecting part to the door frame. Both assembly and disassembly are relatively convenient.

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

[0019] In this solution, with the above structure, the second connecting part is in an inverted U shape and is clamped on the door body through the receiving groove. The two side plates are respectively abutted against the front and back surfaces of the door body, and the fixing effect is good.

[0020] Preferably, it further includes a guiding mechanism. The guiding mechanism includes a slider and a slide rail. The relative lifting between the door body and the door frame is realized through the slider and the slide rail, and the slider is slidably connected to the slide rail; one of the slide rail and the slider is arranged on the door frame through the threaded hole.

[0021] In this solution, with the above structure, both the guiding mechanism and the first connecting part of the transportation and fixing mechanism are fixed through the same threaded hole, further improving the space utilization rate.

[0022] Preferably, the first connecting part and the second connecting part are integrally formed.

[0023] In this solution, with the above structure, the integral forming process can increase the strength of the first connecting part and the second connecting part.

[0024] A battery swapping station includes a channel opening and closing device for the entry and exit of the battery swapping equipment as described above.

[0025] In this solution, with the above structure, through the transportation and positioning mechanism, the door frame and the door body can be fixed to prevent the door body from moving relative to the door frame. During transportation, by installing the transportation and fixing mechanism on the channel opening and closing device for the entry and exit of the battery swapping equipment, it can avoid the relative movement of the door body relative to the door frame due to factors such as bumps and tilts during transportation, avoid damaging the channel opening and closing device, and can also avoid the situation where the chain disengages from the first sprocket due to the loss of vertical gravity constraint or bumps.

[0026] The positive and progressive effects of the present invention are as follows: The present invention discloses a channel opening and closing device for the entry and exit of a battery swapping device and a battery swapping station. The channel opening and closing device for the entry and exit of the battery swapping device can fix the door frame and the door body through a transportation positioning mechanism, preventing the door body from moving relative to the door frame. During transportation, by installing the transportation fixing mechanism on the channel opening and closing device for the entry and exit of the battery swapping device, it is possible to avoid the movement of the door body relative to the door frame caused by factors such as jolting and tilting during transportation, avoid damaging the channel opening and closing device, and also avoid the situation where the chain disengages from the first sprocket due to the loss of vertical gravity constraint or jolting.

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

[0055] This embodiment provides a battery swapping station, which includes at least one battery compartment and an operation compartment. The battery compartment is used to store batteries and charge the batteries, and the operation compartment is used for an electric vehicle to drive in and replace the battery. The battery swapping station moves between the battery compartment and the operation compartment through battery swapping equipment and completes tasks such as transporting, installing, disassembling, and placing the battery. Due to the requirements of the battery working environment and safety, the battery compartment needs to be provided 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 swapping equipment enter or leave the battery swapping station.

[0056] Such as Figure 1As shown in the figure, this embodiment provides a channel opening and closing device for the entry and exit of a battery swapping device, including a door frame 10, a door body 20, a driving mechanism 50, and a transmission mechanism 40. The door body 20 can move up and down within the door frame 10. The door frame 10 is arranged in a battery swapping station. The transmission mechanism 40 is connected to the door body 20, and the driving mechanism 50 drives the transmission mechanism 40 to move, driving the door body 20 to move up and down through the transmission mechanism 40. The transmission mechanism 40 at least includes a chain 41 and a first sprocket 42 arranged 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 transportation fixing mechanism 60. One end of the transportation fixing mechanism 60 is fixed to the door frame 10, and the other end of the transportation fixing mechanism 60 is fixed to the door body 20 to fix the door frame 10 and the door body 20. Specifically, the channel opening and closing device of this embodiment is a lifting type. 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. Both the transmission mechanism 40 and the driving mechanism 50 are arranged above the door body 20, above the highest position of the door body 20's movement position. The transmission mechanism 40 includes a chain 41 and at least one first sprocket 42. The two ends of the chain 41 are respectively connected to the driving mechanism 50 and the door body 20, and are turned by bypassing the first sprocket 42, so that the driving mechanism 50 can drive the door body 20 to move up and down in the vertical direction along the horizontal direction. In addition to the first sprocket 42, the transmission mechanism 40 can also be provided with multiple groups of sprockets to guide and bend the chain 41, so that the chain 41 can be arranged in an appropriate position, without occupying the space of other components, and it is also convenient to arrange the driving mechanism 50 in an appropriate position according to requirements. Since the transmission mechanism 40 includes multiple sprockets and a chain 41, in the assembled state, the door body 20 can tighten the chain 41 by its own gravity so that the chain 41 can be fixed on the sprocket. However, when the channel opening and closing device needs to be transported, during the transportation process, the channel opening and closing device is not always vertically arranged and stable. It is very likely to be tilted, skewed or jolted, so that the weight of the door body 20 cannot restrain the chain 41 to make it taut, which may cause the chain 41 to lose its restraint force and become loose and then come out of the sprocket. This will cause structural damage or reduce the assembly efficiency. Therefore, before transportation, a transportation positioning mechanism will be assembled on the door body 20. One end of the transportation positioning mechanism 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 transportation 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 the transportation process, by installing the transportation fixing mechanism 60 on the channel opening and closing device for the entry and exit of the battery swapping device, it can avoid the movement of the door body 20 relative to the door frame 10 caused by factors such as jolting and tilting during transportation, avoid damaging the channel opening and closing device, and can also avoid the situation where the chain 41 comes out of the first sprocket 42 due to the loss of vertical gravity constraint or jolting.

[0057] AsFigure 2 As shown, the transportation 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 at the top surface. The door body 20 is connected to the longitudinal beams 11 of the door frame 10, and the moving direction of the door body 20 is consistent with the extending direction of the longitudinal beams 11. The transportation fixing mechanism 60 is clamped at the top surface in the moving direction of the door body 20 and fixed to the longitudinal beam 11, blocking the upward movement of the door body 20 on the moving path of the door body 20. It can further enhance the limiting effect on the longitudinal lifting movement of the door body 20, and the fixing effect is better.

[0058] Preferably, as Figure 2 shown, the transportation fixing mechanism 60 is arranged at the top end corner of the door body 20. The installation position is suspended at the end corner of the door body 20, and the distances from this position to the longitudinal beam 11 and to the top surface of the door body 20 are the closest, enabling the transportation fixing mechanism 60 to simply connect the door frame 10 and the top surface of the door body 20, reducing its structural complexity, and thus enhancing the space utilization rate and the structural strength of the transportation fixing mechanism 60.

[0059] In other embodiments, the transportation fixing mechanism 60 can also be arranged at other positions, such as the side surface or the bottom surface of the door body 20. Its connection to the door frame 10 is not limited to the side of the longitudinal beam 11 facing the door body 20, and it can also be arranged on the longitudinal beam 11 or other structures, such as one end abuts against the cross beam 12 in the vertical direction and the other end waits on the door body 20, etc. Generally speaking, the transportation fixing mechanism 60 only needs to ensure the relative fixation of the door body 20 and the door frame 10 to function. Only the installation position in this embodiment has the simplest and most compact structure and good fixing effect.

[0060] In this embodiment, the specific structure of the transportation fixing mechanism 60 is as Figure 3 、 Figure 4 shown, including two first connection parts 61 and a second connection part 62 arranged at an angle. The first connection part 61 and the second connection part 62 are in an L shape. The first connection part 61 connects the door frame 10, and the second connection part 62 connects the top surface of the door body 20. The L-shaped structure has strong torsional resistance, can further strengthen the fixing effect between the door frame 10 and the door body 20, and strengthen the limiting effect on the lifting movement of the door body 20. In addition, the L-shaped structure also corresponds to the triangular shape of the end corner position of the door body 20 and the longitudinal beam 11, enabling the two sides of the L shape to fit and connect the top surface of the door body 20 and the side surface of the longitudinal beam 11. Preferably, the inner sides of the first connection part 61 and the second connection 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 in the figure, the guiding mechanism 30 includes a slider 32 and a slide rail 31. The relative lifting between the door body 20 and the door frame 10 is realized through the slider 32 and the slide rail 31, and 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 guiding mechanism 30 of this embodiment is arranged between the door body 20 and the longitudinal beam 11 of the door frame 10. The slide rail 31 is arranged on the side surface of the longitudinal beam 11 facing the door body 20, and the slider 32 is connected to the door body 20 and 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, protruding outward from the longitudinal beam 11, while the door body 20 is provided with a groove structure to be clamped and slide on the longitudinal beam 11. The slide rail 31 is fixed on the longitudinal beam 11 through a threaded hole 111 pre-opened on the longitudinal beam 11, and this threaded hole 111 is the same as the threaded hole 111 connected to the first connecting portion 61 of the channel opening and closing device. The first connecting portion 61 of the guiding mechanism 30 and the transportation fixing mechanism 60 are both fixed through the same threaded hole 111, further improving the space utilization rate.
