Technical Field

[0002] The present application relates to the field of battery replacement, and in particular to a passage opening and closing device for the entry and exit of battery replacement equipment and a battery replacement station including the same. Background Art

[0003] 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.

[0004] In existing battery swap stations, the opening and closing devices of the access openings of the battery swap equipment generally use a driving device to directly drive the door panel in the direction of movement of the door panel, and a large amount of space needs to be reserved for the movement of the driving device. In addition, the setting of the driving device is also prone to obstruction by the position of other device structures in the battery swap station, and the driving device of the access opening and closing device cannot be flexibly set, resulting in low space utilization inside the battery swap station. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the channel opening and closing device in the prior art in that the location is inflexible and the space utilization rate is low, and to provide a channel opening and closing device for the entry and exit of battery swapping equipment and a battery swapping station including the same.

[0008] The transmission mechanism includes a pulley block and a traction rope, the traction rope passes over the pulley block, one end of the traction rope is connected to the driving end of the driving part, and the other end of the traction rope is connected to the connecting end of the lifting part;

[0009] The pulley group includes a first pulley group, which is arranged on a straight line where the driving end of the driving part moves along the first direction; the pulley group also includes a second pulley group, which is arranged on a straight line where the connecting end of the lifting part moves along the second direction; the traction rope passes around the first pulley group and the second pulley group in sequence.

[0010] In this solution, the channel opening and closing device can open the channel opening according to the needs of the battery swap equipment, so that the battery swap station can remain closed when not in operation, ensuring that the battery compartment is isolated from the outside world and will not be damaged by the outside world, and the internal temperature control is more stable. At the same time, it can be opened automatically in the working state to ensure the entry and exit of the battery swap equipment. In addition, the moving direction of the driving part of the channel opening and closing device is not parallel to the moving direction of the lifting part, which can reduce the space occupied by the channel opening and closing device in the lifting direction of the lifting part, avoid obstruction with the position of other device structures in the battery swap station, and help improve the space utilization rate in the battery swap station.

[0011] In addition, the transmission mechanism using a pulley block is more labor-saving, and the pulley block can flexibly change the traction direction, which is convenient for changing the setting position of the driving device of the channel door opening and closing device, avoiding obstruction with other device structures in the battery swap station, and improving the space utilization rate in the battery swap station. The first pulley block is set at the above position. On the one hand, it is convenient for the driving unit to effectively transfer power to the first pulley block, which is conducive to improving the driving efficiency. On the other hand, the layout is compact and reasonable, which is also conducive to reducing the space occupied by the overall channel opening and closing device.

[0021] In this solution, a ring nut is used as the intermediate connecting piece, which has a simple and strong structure and is conducive to simplifying the overall structure of the channel opening and closing device. The connection between the traction rope and the ring nut can be achieved by wrapping the traction rope around the wall of the ring nut for one circle and tying a knot, without the need to set up an additional connection structure, which not only simplifies the structure, but also reduces the driving resistance, and also facilitates the subsequent disassembly or replacement of the traction rope, thereby improving the maintainability of the channel opening and closing device.

[0026] In this solution, the solenoid valve is used to control the working state of the cylinder to drive the movement of the telescopic rod, which can quickly switch the state of the driving part, thereby helping to improve the efficiency and reliability of the lifting and lowering of the lifting part and the reliability of battery replacement.

[0027] Preferably, the lifting part and the mounting part are lifted and lowered relative to each other via a slider and a slide rail, and the slider is slidably connected to the slide rail; the slide rail and the slider are respectively arranged on the mounting part and the lifting part.

[0028] In this solution, relative lifting is achieved through the cooperation of the slider and the slide rail, the structure is simple, and the slide rail can play a guiding role, which is conducive to ensuring the reliability of the lifting of the lifting part.

[0029] Preferably, a slide groove is provided on the slide rail, and the slide block has a matching portion; wherein the matching portion is inserted into the slide groove and slidingly matched with the slide rail.

[0030] In this solution, the slide groove can be nested with the mating part to prevent the slide groove from escaping from the mating part during sliding, which is beneficial to ensuring the lifting reliability of the lifting part, so as to ensure that the channel door can reliably switch between opening and closing according to actual power replacement needs.

[0031] Preferably, the slide rail is fixed on a side wall of the mounting portion, and the slider is fixed on a side of the lifting portion facing the interior of the battery swap station through a mounting bracket.

[0032] In this solution, the slider is fixed to the lifting part by means of a mounting bracket, which is beneficial to increase the contact area between the slider and the lifting part, thereby increasing the reliability of the connection between the slider and the lifting part. In addition, the mounting bracket also facilitates the connection between the slider and the lifting part.

[0033] Preferably, the passage opening and closing device further comprises a detection device, which is arranged on the mounting portion; the detection device is configured such that when the lifting portion rises to a preset position, the detection device contacts the lifting portion to detect whether the lifting portion is in place.

[0034] In this solution, the lifting and lowering of the lifting part is detected by the detection equipment, so as to determine whether the lifting part is in place, which is beneficial to the automatic control of the opening and closing of the passage.

[0035] Preferably, the passage opening and closing device further comprises a railing component, wherein the railing component is connected to a side of the lifting portion facing the outside of the battery swap station and extends in a direction away from the lifting portion.

[0036] In this solution, the guardrail component extends outward to serve as a warning and barrier to prevent people from approaching the lifting part. When the lifting part is opened, the guardrail component is driven up, which can effectively and safely prevent passenger car drivers from opening the door and getting off the car during the battery replacement process, which is conducive to improving safety.

[0037] Preferably, a rubber pad is provided at the outer end of the railing component away from the lifting part; and a preset distance is provided between the outer end of the railing component away from the lifting part and the door of the battery-swap vehicle.

[0038] In this solution, the rubber pad can play a buffering role to prevent the railing parts from directly colliding with the outside world. In addition, by setting the interval at a preset distance, it can prevent people from opening the door and leaving during the battery replacement process, avoiding safety hazards.

[0039] The present invention also provides a battery swap station, including a battery swap platform, a charging compartment and a battery swap device. The charging compartment is arranged on at least one side of the battery swap platform perpendicular to the driving direction of the electric vehicle. The battery swap device travels back and forth between the battery swap platform and the charging compartment to exchange batteries. The battery swap station also includes a passage opening for the battery swap device to enter and exit the charging compartment. The passage opening is provided with the above-mentioned passage opening opening and closing device, and the passage opening opening and closing device is used to open or close the passage opening.

[0040] In this solution, the battery swap station can open the entrance and exit of the channel according to the entry and exit needs of the battery swap equipment by setting the above-mentioned channel opening and closing device, so that the battery swap station can remain closed in the non-working state, ensuring that the battery compartment is isolated from the outside world and will not be damaged by the outside world, and the internal temperature control is more stable. At the same time, it can be opened automatically in the working state to ensure the entry and exit of the battery swap equipment. In addition, the moving direction of the driving part of the channel opening and closing device is not parallel to the moving direction of the lifting part, which can reduce the space occupied by the channel opening and closing device in the lifting direction of the lifting part, avoid obstruction with the position of other device structures in the battery swap station, and help to improve the space utilization rate in the battery swap station.

[0041] Preferably, a charging rack is provided in the charging compartment for charging and discharging the battery, and the mounting portion is fixed on the charging rack;

[0042] Alternatively, the mounting portion is connected to a box structure located between the battery swap compartment and the charging compartment in the battery swap station.

[0044] The positive and progressive effects of the present invention are:

[0045] In the channel opening and closing device, the entrance and exit channel can be opened according to the entry and exit needs of the battery swapping equipment, so that the battery swapping station can remain closed in the non-working state, ensuring that the battery compartment is isolated from the outside world and will not be damaged by the outside world, and the internal temperature control is more stable. At the same time, it can be opened automatically in the working state to ensure the entry and exit of the battery swapping equipment.

[0079] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0080] This embodiment discloses a channel opening and closing device for the entry and exit of a battery swapping device, which is used in a battery swapping station. The battery swapping station of this embodiment may include a battery swapping platform, a charging compartment and a battery swapping device. The charging compartment is arranged on at least one side of the battery swapping platform perpendicular to the driving direction of the electric vehicle. The battery swapping device travels back and forth between the battery swapping platform and the charging compartment to exchange batteries. The battery swapping station also includes a channel opening for the battery swapping device to enter and exit the charging compartment. A channel opening and closing device is arranged on the channel opening, and the channel opening and closing device is used to open or close the channel opening. Of course, in other embodiments, this embodiment can be applied to other types of battery swapping stations or charging stations to open and close the channel opening.

[0081] like Figure 1-5 As shown, the passage opening and closing device includes a mounting portion 10, a lifting portion 20, a driving portion 30 and a transmission mechanism 40, wherein the lifting portion 20 is mounted on the battery swap station through the mounting portion 10, and the transmission mechanism 40 is transmission-connected between the driving portion 30 and the lifting portion 20; the driving end of the driving portion 30 moves along a first direction, and drives the lifting portion 20 to rise and fall along a second direction through the transmission mechanism 40 to open or close the passage opening; wherein the first direction is not parallel to the second direction.

[0082] In this embodiment, the entrance and exit passage can be opened according to the entry and exit needs of the battery swap equipment, so that the battery swap station can remain closed in the non-working state, ensuring that the battery compartment is isolated from the outside world and will not be damaged by the outside world, and the internal temperature control is more stable. At the same time, it can be automatically opened in the working state to ensure the entry and exit of the battery swap equipment. The moving direction of the drive unit 30 is not parallel to the moving direction of the lifting unit 20, which can reduce the space occupied by the passage opening and closing device in the lifting direction of the lifting unit 20 (i.e., the second direction), avoid the position of the drive unit 30 and other device structures in the battery swap station from being blocked, which is conducive to improving the space utilization rate in the battery swap station.

[0083] Below the joint Figure 1-3 , the structure of the transmission mechanism 40 is described in detail.

[0084] like Figure 1-3 As shown, in a preferred embodiment, the transmission mechanism 40 includes a pulley block and a traction rope, the traction rope passes through the pulley block, one end of the traction rope is connected to the driving end of the driving part 30, and the other end of the traction rope is connected to the connecting end of the lifting part 20. The transmission mechanism 40 adopts a pulley block mechanism, which is more labor-saving, and the pulley block can flexibly change the traction direction, thereby facilitating the change of the setting position of the driving device 30 of the channel door opening and closing device, avoiding obstruction with other device structures in the battery swap station, and improving the space utilization rate in the battery swap station.

[0085] It should be noted that the structure of the transmission mechanism 40 is not limited to the above-mentioned structure including a pulley combined with a traction rope. In other alternative embodiments, other corresponding structures that can change the transmission direction may also be used.

[0086] Furthermore, if Figure 1-2 As shown, the pulley block includes a first pulley block 401, and the first pulley block 401 is arranged on a straight line where the driving end of the driving unit 30 moves along the first direction. The first pulley block 401 is arranged at the above position. On the one hand, it is convenient for the driving unit 30 to effectively transmit power to the first pulley block 401, which is conducive to improving the driving efficiency. On the other hand, the layout is compact and reasonable, which is also conducive to reducing the space occupied by the overall channel opening and closing device.

[0087] As a preferred embodiment, Figure 1-3 As shown, the first direction is perpendicular to the second direction, and the driving unit 30 and the first pulley block 401 are arranged at the top of the mounting portion 10 along the first direction. Among them, the first pulley block 401 is arranged at the above position. On the one hand, it is conducive to further ensuring that the driving unit 30 effectively transmits the force to the first pulley block 401. On the other hand, the space at the top of the mounting portion 10 is generally an empty space, which is not easy to be blocked by the position of other devices. By arranging the driving unit and the pulley block here, the space utilization rate in the battery swap station can be effectively improved.

[0088] In a preferred embodiment, Figure 1-2 As shown, the pulley block further includes a second pulley block 402, which is arranged on a straight line where the connecting end of the lifting part 20 moves along the second direction; the traction rope sequentially passes around the first pulley block 401 and the second pulley block 402. With such an arrangement, the second pulley block 402 can more effectively transmit the driving force from the driving part 30 to the lifting part 20, which is conducive to further improving the driving efficiency.

[0089] like Figure 1-2 As shown, the traction rope includes a first traction rope 403 and a second traction rope 404, one end of the first traction rope 403 and the second traction rope 404 are connected to the driving part 30, and the other end is respectively connected to the first connection end and the second connection end arranged on both sides of the lifting part 20; wherein, the second pulley group 402 includes a third pulley 407 and a fourth pulley 408, and the third pulley 407 and the fourth pulley 408 are respectively arranged on the side walls of the mounting part 10.

[0090] In this embodiment, pulleys and traction ropes are provided on both sides of the lifting part 20, thereby driving the two sides of the lifting part 20 to slide relative to the mounting part 10, so that the force on the lifting part 20 is relatively balanced and the lifting process is relatively smooth. In addition, in the event of an accident such as the breakage of the traction rope on one side, the lifting part 20 will not fall due to the connection of the traction rope on the other side, thereby improving the safety and reliability of the battery swap station. It can be understood that providing traction ropes on both sides of the lifting part 20 is a relatively balanced solution between cost and stability. In other optional embodiments, in order to further improve the traction effect, more traction ropes can also be provided to be connected at different positions of the lifting part 20.

[0091] In a preferred embodiment, Figure 2-3 As shown, the first pulley group 401 includes a first pulley 405 and a second pulley 406; the first traction rope 403 passes around the first pulley 405 and the third pulley 407 in sequence, and the second traction rope 404 passes around the second pulley 406 and the fourth pulley 408 in sequence.

[0092] Among them, by changing the driving end to drive the moving direction of the first traction rope 403 and the second traction rope 404 through the first pulley group 401, the connection between the driving part 30 and the third pulley 407 and the fourth pulley 408 can be realized at the same time, and then the moving directions of the first traction rope 403 and the second traction rope 404 are changed again by the third pulley 407 and the fourth pulley 408 respectively, so that they are parallel to the moving direction of the lifting part 20, which is beneficial to simplify the overall structure and reduce the space occupied by the overall channel door opening and closing device, and the first traction rope 403 and the second traction rope 404 are respectively bypassed around the corresponding third pulley 407 and the fourth pulley 408 in turn, so that they are respectively connected to the two sides of the lifting part 20 along the second direction, which is beneficial to improve the reliability of the lifting and lowering of the lifting part 20.

[0093] In a preferred embodiment, Figure 1 and Figure 3 As shown, in order to facilitate the connection between the traction rope and the driving unit 30, an intermediate connector 50 is further provided, and the driving unit 30 further includes the intermediate connector 50, which is connected to the driving end of the driving unit 30, and the traction rope is connected to the driving end through the intermediate connector 50. When there are multiple traction ropes, the intermediate connector 50 can effectively improve the firmness of the connection between the traction rope and the driving unit 30.

[0094] As an illustrative embodiment, the intermediate connecting member 50 is provided as a ring nut.

[0095] The ring nut is used as the intermediate connecting member 50, which has a simple and strong structure and is conducive to simplifying the overall structure of the passage opening and closing device. The connection between the traction rope and the ring nut can be achieved by wrapping the traction rope around the wall of the ring nut for one circle and tying a knot, without the need to set up an additional connection structure, which not only simplifies the structure, but also reduces the driving resistance, and also facilitates the subsequent removal or replacement of the traction rope, thereby improving the maintainability of the passage opening and closing device.

[0096] Below the joint Figure 1-3 , the structure of the lower driving unit 30 is specifically described.

[0097] In a preferred embodiment, Figure 1 and Figure 3 As shown, the driving unit 30 includes a power source 301 and a telescopic rod 302. The power source 301 drives the telescopic rod 302 to move. One end of the telescopic rod 302 is a driving end, and the other end is connected to the power source 301. The driving unit 30 adopts a telescopic rod structure, which is relatively simple and durable, has a long service life, occupies less space inside the power station, and the driving structure of the telescopic rod 302 has a strong driving force, can drive a heavy door panel, and has good applicability.

[0098] Specifically, in this embodiment, the power source 301 is a cylinder. The cylinder can be mounted on the top of the mounting 100 through a bracket. Figure 1 and Figure 3 As shown, the channel opening and closing device also includes a solenoid valve 303, which is arranged on the mounting portion 10; the solenoid valve 303 is connected to the cylinder through an air pipe to control the operation of the driving portion 30. In addition, the solenoid valve 303 is mounted on the mounting portion 10 through a first mounting bracket 304. The solenoid valve 303 can be used to relatively quickly switch the state of the driving portion 30, which is beneficial to improve the efficiency and reliability of the lifting and lowering of the lifting portion 20, and is beneficial to improve the reliability of power replacement.

[0099] In a preferred embodiment, an air compressor is provided in the battery swap station, and the air compressor is connected to the air inlet of the solenoid valve 303 through an air pipe, and the air outlet of the solenoid valve 303 is connected to the cylinder through an air pipe. Thus, by controlling the opening and closing of the solenoid valve 303, the connection state of the air compressor to the cylinder is controlled, thereby controlling the working state of the cylinder.

[0100] It should be noted that in other alternative embodiments, the power source 301 can also be set as other power devices such as a hydraulic cylinder or a motor to drive the telescopic rod 302, and a control component corresponding to the power source 301 is provided in the battery swap station.

[0101] like Figure 1-3As shown in the figure, as an exemplary embodiment, the lifting part 20 and the mounting part 10 are lifted relative to each other through the slider 70 and the slide rail 60, and the slider 70 is slidably connected with the slide rail 60; the slide rail 60 and the slider 70 are respectively arranged on the mounting part 10 and the lifting part 20. The relative lifting is achieved by the cooperation of the slider 70 and the slide rail 60, the structure is simple, and the slide rail 60 can play a guiding role, which is conducive to ensuring the reliability of the lifting of the lifting part 20.

[0102] In a preferred embodiment, a slide groove is provided on the slide rail 60, and the slider 70 has a matching portion, wherein the matching portion is inserted into the slide groove and slides with the slide rail 60. The slide groove can be nested with the matching portion, thereby preventing the slide groove from being disengaged from the matching portion during sliding, and can also better guide the movement of the slider 70 on the slide rail 60, thereby facilitating the lifting reliability of the lifting portion 20, so as to ensure that the channel door can be reliably switched between opening and closing according to the actual power replacement needs.

[0103] Furthermore, a sliding surface may be provided on the side where the slider 70 and the slide rail 60 slide together. The sliding surface may be made of a polymer material, such as polyethylene, polytetrafluoroethylene, ceramic composite material, etc. The sliding surface of the polymer material is smoother, which reduces the resistance when the slider 70 and the slide rail 60 slide relative to each other, and has good wear resistance and a long service life. The sliding surface may be provided on the surface of the side where the slider 70 and the slide rail 60 cooperate by gluing, riveting or clamping.

[0104] It should be noted that in other alternative embodiments, the slider 70 may also adopt other structures to achieve the relative lifting between the mounting portion 10 and the lifting portion 20, such as using guide wheels, sliders and other structures, but is not limited to the above structure.

[0105] like Figure 1-4 As shown, the slide rail 60 is fixed on the side wall of the mounting portion 10, and the slider 70 is fixed on the side of the lifting portion 20 facing the inside of the battery swap station through the second mounting bracket 80. The slider 70 is fixed to the lifting portion 20 through the second mounting bracket 80, which is conducive to increasing the contact area between the slider 70 and the lifting portion 20, thereby increasing the reliability of the connection between the slider 70 and the lifting portion 20. In addition, the second mounting bracket 80 also facilitates the connection between the slider 70 and the lifting portion 20.

In the present embodiment, the fixing member 802 is a threaded fastener, the bending portion 801 is an L-shaped plate, the slider 70 is connected to one side of the bending portion 801 through the fixing member 802, and the other side of the bending portion 801 is connected to the side of the lifting portion 20 facing the inside of the battery swap station through the fixing member 802, thereby realizing a fixed connection between the slider 70 and the lifting portion 20 without hindering the relative sliding between the slider 70 and the slide rail 60.

[0107] like Figure 2 As shown, the passage opening and closing device further includes a detection device 90, which is arranged on the mounting portion 10. The detection device 90 may specifically be a travel switch or other components; the detection device 90 is configured such that when the lifting portion 20 rises to a preset position, the detection device 90 contacts the lifting portion 20 to detect whether the lifting portion 20 is in place. The detection device 90 detects the lifting of the lifting portion 20, thereby determining whether the lifting portion 20 is in place, which is beneficial to the automatic control of the passage opening and closing device.

[0108] In a preferred embodiment, Figure 5 As shown, the passage opening and closing device also includes a guardrail component 100, which is connected to the side of the lifting part 20 facing the outside of the battery swap station and extends away from the lifting part 20. The guardrail component 100 extends outward to play a role of prompting and blocking, preventing people from approaching the lifting part 20. When the lifting part 20 is opened, the guardrail component 100 is driven to rise, which can effectively and safely prevent the passenger car driver from opening the door and getting off the car during the battery swap process, avoiding safety hazards and helping to improve safety.

[0109] Furthermore, if Figure 5 As shown, a rubber pad 110 is provided at the outer end of the railing component 100 away from the lifting part 20, and the rubber pad 110 can play a buffering role to prevent the railing component 100 from directly colliding with the outside world. In addition, by setting the interval at a preset distance, it is possible to prevent people from opening the door and leaving during the battery replacement process, thereby avoiding safety hazards.

[0110] In a preferred embodiment, the rubber pad 110 is strip-shaped, and the strip-shaped rubber pad 110 is respectively fixedly connected to the outer ends of the plurality of railing components 100. Thus, a continuous extended barrier can be achieved through one rubber pad 110, and the buffering area of ​​the rubber pad 110 is increased, resulting in a better buffering effect.

[0111] There is a preset distance between the outer end of the railing component 100 away from the lifting part 20 and the door of the battery swapping vehicle. The specific distance between the outer end of the railing component 100 and the door can be determined according to factors such as the parking position of the vehicle in the battery swapping station and the width of the battery swapping channel. For example, in a preferred embodiment, the preset distance of the interval is greater than 100 mm.

[0112] The present embodiment also provides a battery swap station, including a battery swap platform, a charging compartment and a battery swap device. The charging compartment is arranged on at least one side of the battery swap platform perpendicular to the driving direction of the electric vehicle.

The battery swap station also includes a passage opening for the battery swap device to enter and exit the charging compartment. The passage opening is provided with the above-mentioned passage opening opening closing device, which is used to open or close the passage opening.

[0113] By providing the above-mentioned passage opening and closing device, the battery swap station can open the passage opening according to the entry and exit needs of the battery swap equipment, so that the battery swap station can remain airtight in the non-working state, ensuring that the battery compartment is isolated from the outside world and will not be damaged by the outside world, and the internal temperature control is more stable. At the same time, it can be opened automatically in the working state to ensure the entry and exit of the battery swap equipment. In addition, the moving direction of the driving part 30 of the passage opening and closing device is not parallel to the moving direction of the lifting part, which can reduce the space occupied by the passage opening and closing device in the lifting direction of the lifting part 20, avoid obstruction with the position of other device structures in the battery swap station, and help to improve the space utilization rate in the battery swap station.

[0114] Furthermore, a charging rack is provided in the charging compartment for charging and discharging the battery, and the mounting portion 10 is fixed on the charging rack; or, the mounting portion 10 is connected to a box structure located between the battery swap compartment and the charging compartment in the battery swap station.

[0115] Among them, by fixing or installing the mounting part 10 on the charging rack or the box structure, the existing structure can be fully utilized, avoiding adding fixed structures and occupying more internal space, thereby further improving the space utilization inside the battery swap station.
