Description

Technical Field

[0001] This application relates to the field of battery swapping station technology, and in particular to a heavy-duty truck battery swapping station with wing doors. Background Technology

[0002] Heavy-duty truck battery swapping stations are dedicated facilities providing rapid battery replacement services for new energy heavy-duty trucks. They adopt a "vehicle-battery separation" model, solving the range problem of electric heavy-duty trucks through shared and leased batteries. Hoisting-type heavy-duty truck battery swapping stations use hoisting equipment to remove depleted batteries and then lift and install fully charged batteries onto the new energy heavy-duty trucks, thus completing a rapid battery swap and increasing range.

[0003] Current containerized battery swapping stations designate the side doors as a single, integrated structure. When the station is operational, the side doors flip open around the top, providing cover. The drawback of this design is that the drive mechanism supporting the side door is directly exposed after the side door is raised. In rainy or snowy weather, wind and other factors can easily expose the drive mechanism to direct contact with rainwater, necessitating waterproofing. However, long-term use can still reduce the lifespan of the drive mechanism. Some containerized battery swapping stations use mechanical structures like cylinders to support the side doors. These cylinder structures are also typically exposed. Although shielded by the side door, these structures still need to be located at both ends of the side door for stability. This makes the drive mechanism susceptible to rainwater exposure, further reducing its lifespan. Summary of the Invention

[0004] The purpose of this application is to provide a heavy-duty truck battery swapping station that allows for convenient control of the opening of the wing doors and station building.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A heavy-duty truck battery swapping station with a wing door includes a station building, a wing door located at the side door of the station building, and a drive mechanism for driving the wing door to open and close. A first fixing part and a second fixing part are provided between the wing door and the station building. The station building has a battery swapping entrance / exit on at least one side wall. The first fixing part is adapted to allow the wing door to be rotatably mounted on the station building, and the second fixing part is adapted to keep the wing door at a set angle. When the wing door is unfolded, it corresponds to the position of the battery swapping entrance / exit. The height of the wing door in the unfolded state is equal to or greater than the top height of the station building, and the wing door in this state is aligned with the station building. The wing door is fitted together at the top edge or the top of the side, and a gap is formed between the wing door and the side wall of the station building when it is retracted; the second fixing part extends from the interior of the station building or the side wall to connect with the wing door, so that the drive mechanism is set inside the station building. The drive mechanism is adapted to drive the second fixing part to move inside the station building so that the wing door can adjust its angle and be fixed; at least one side of the battery swapping entrance / exit is provided with a sliding door, and a transmission structure is provided inside the station building. The transmission structure is adapted to move in response to the opening / closing of the wing door so that the sliding door opens / closes accordingly, thereby opening / closing the battery swapping entrance / exit when the wing door opens / closes.

[0006] As a preferred embodiment, the transmission structure and the action point of the moving door are provided with a hysteresis structure, which is adapted to cause the moving door to act and open after the wing door has been opened to a set position.

[0007] As a preferred embodiment, the transmission structure includes a first link hinged to the second fixed part and a second link connected to the movable door. The first link and the second link are hinged together. The second link restricts sliding movement in the horizontal direction at both ends of the top of the battery swapping entrance / exit. When the wing door is opened, one end of the second fixed part connected to the station building rises, and this end drives the other end of the first link to move away from the battery swapping entrance / exit, so that the movable door leaves the battery swapping entrance / exit.

[0008] As a preferred embodiment, both sides of the battery swapping entrance / exit are provided with sliding grooves, and the station building is provided with a first sliding sleeve corresponding to the sliding grooves. The end of the second fixed part is provided with a hinge block, which passes through the sliding groove and enters the inner cavity of the first sliding sleeve. The first sliding sleeve is provided with a clearance groove on the side of the station building away from the battery swapping entrance / exit, and the hinge block forms a connecting protrusion through the clearance groove. The connecting protrusion is hinged to the first connecting rod. The top of the inner wall of the side of the station building where the battery swapping entrance / exit is located is provided with a second sliding sleeve for restricting the movement of the second connecting rod. The second connecting rod passes through the second sliding sleeve and is fixedly connected to the sliding door.

[0009] More preferably, the second link is telescopic. During the process of the wing door opening from closed, the second link first extends to its limit and then pulls the movable door open, so that the wing door and the movable door open sequentially. The second link includes a first rod body, a second rod body, and a telescopic structure for adjustment. The first rod body and the second rod body are sleeved together, and the telescopic range is adjusted by the telescopic structure.

[0010] As a preferred embodiment, the transmission structure includes a pulley and a rope for transmission. The drive mechanism is a winch, and the rope is wound around the winch. The end of the rope is connected to the slider. When the winch starts winding, the rope pulls the slider upward to open the wing door. The rope is deflected by the pulley to create a horizontal movement section. This section has at least two actuating parts, and the movable door has a mating part. The at least two actuating parts are respectively located on both sides of the mating part. When the wing door opens, the actuating parts act on the mating part to open the movable door. When the wing door closes, the winch reverses, and the wing door pulls the rope taut by gravity, causing the rope to return to its original position under the combined action of the wing door's gravity and the winch's reverse rotation.

[0011] More preferably, the rope is provided with a plurality of actuating parts at equal intervals, and the movable door is provided with a plurality of mating parts at corresponding intervals. When mating, after the wing door opens a certain distance, the actuating parts move to a state of contact with the mating parts, thereby actuating to open the movable door; adjusting the spacing between the actuating parts and correspondingly increasing the spacing between the mating parts adjusts the distance when the actuating parts and the mating parts reach the contact state during operation, so that the wing door and the movable door open sequentially.

[0012] As a preferred embodiment, the first fixing part includes at least two hinge seats fixedly installed on both sides of the battery swapping entrance / exit. Each hinge seat is provided with a connecting part, which is connected to the wing door. The connecting part is adapted to increase the distance between the wing door and the side wall of the station building after installation. The connecting part is located at a set height below the top surface of the wing door so that the top of the wing door in the unfolded state covers the gap formed between the wing door and the station building.

[0013] As a preferred embodiment, the heavy-duty truck battery swapping station further includes a hoisting device. The hoisting device is used to hoist the batteries inside the station building from the battery swapping entrance / exit to the outside, and is adapted to lower the batteries and install them onto the battery swapping truck. At the same time, the hoisting device is adapted to remove the depleted batteries from the truck and hoist them to a designated position. The hoisting device is provided with a traveling structure on the ceiling inside the station building. The traveling structure is adapted to send the outer end of the hoisting device out of the battery swapping entrance / exit after the wing door is opened.

[0014] As a preferred embodiment, a folding canopy is provided in the middle of the side of the wing door, and the other side of the folding canopy is fixedly installed on the wall of the station building. When the folding canopy is unfolded, it is fan-shaped. When the wing door is retracted, the folding canopy is stored in the gap formed between the wall of the station building and the wing door.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: When the wing door is in its extended state, its height is equal to or greater than the height of the station building's roof. In this state, the wing door fits snugly against the edge of the roof or the top of the side of the station building. This design prevents the wing door from fitting snugly against the edge of the roof or the side of the station building after it is extended, ensuring a good sealing effect after installation. On the other hand, this design makes it easier to install the drive mechanism inside the station building, thereby reducing the impact of the environment on the drive mechanism and increasing its service life.

[0016] The wing door acts on the sliding door through a transmission structure. When the wing door opens, the sliding door also gradually opens; when the wing door closes, the sliding door also gradually closes. This sliding door does not require an additional drive structure and can ensure that the sliding door only opens when the wing door opens. This conforms to the opening and closing logic of the wing door and the sliding door in daily use, ensuring the normal operation of the battery swapping station.

[0017] By using a delayed structure, the wing door is opened for a certain period of time before it activates the sliding door and opens. This ensures that the wing door opens only after it has created a shielding effect, thus preventing rain and snow from entering the station building when the sliding door is opened in rainy or snowy weather.

[0032] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0035] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0036] Example: Reference Figures 1 to 11 This application proposes a heavy-duty truck battery swapping station with a wing door, including a station building 1, a wing door 2 located at the side door of the station building 1, and a drive mechanism for opening and closing the wing door 2. Fully charged batteries 4 are installed inside the station building 1 or on its side. When a depleted heavy-duty truck drives to the side of the station building 1, the location of the battery 4 on the heavy-duty truck corresponds to the position of the wing door 2. After the wing door 2 is opened, it can cover the area of ​​the battery 4 on the heavy-duty truck and the gap between the station building 1 and the heavy-duty truck, thereby preventing rain and snow from adversely affecting battery swapping.

[0037] like Figure 1 , Figure 2 The mobile battery swapping station shown mainly consists of a station building 1 and a mounting platform 5 at the bottom. The mounting platform 5 is equipped with structures such as sliding rails 9 to allow for the movable installation of the station building 1. A battery station 4 is located at the rear of the station building 1 to store depleted and fully charged batteries 4. The front of the station building 1 is a heavy-duty truck parking area. When a heavy-duty truck parks, the wing door 2 opens, providing shelter from wind and rain above the location where the batteries 4 are installed. Depleted batteries 4 from the heavy-duty truck are hoisted from the battery swapping entrance / exit 3 and moved to the rear battery station 4. Fully charged batteries 4 are then hoisted from inside the station building 1 or from the battery station 4 and installed on the heavy-duty truck.

[0038] Current containerized battery swapping stations designate the side doors as a single, integrated structure. When the station is operational, the side doors flip open around the top, providing cover. The drawback of this design is that the drive mechanism supporting the side door is directly exposed after the side door is raised. In rainy or snowy weather, wind and other factors can easily expose the drive mechanism to direct contact, requiring waterproofing. However, long-term use can still reduce the lifespan of the drive mechanism. Some containerized battery swapping stations use mechanical structures like cylinders to support the side doors. These cylinder structures are also generally exposed. Although shielded by the side door, these structures still need to be located at both ends of the side door for stability. This makes the drive mechanism susceptible to rain and other damage, further reducing its lifespan.

[0039] In one embodiment of this application, a first fixing part 7 and a second fixing part are provided between the wing door 2 and the station building 1, and a power swapping entrance / exit 3 is provided on one side wall of the station building 1, as shown in the reference. Figure 2 The first fixing part 7 is adapted to allow the wing door 2 to be rotatably mounted on the station building 1, and the second fixing part is adapted to keep the wing door 2 at a set angle. When the wing door 2 is opened, it corresponds to the position of the power swapping entrance / exit 3. The above-mentioned sides can be understood in this application as the four vertical sides of the station building, and the station building 1 is generally set as a container.

[0040] In some embodiments, refer to Figure 13 As shown, Figure 13 The middle wing door is located on the side of the container corresponding to its width, or at the end, and its internal structure can be adjusted as needed. When the wing door 2 is located on the side of the station building 1 corresponding to its width, the lifting guide rail 14 and the traveling structure 21 corresponding to the lifting equipment can be relatively long, allowing for more space inside the station building for replacement batteries and for storing depleted batteries. For ease of demonstration of the internal structure, Figure 13 The station building shown has its top concealed. In this case, station building 1 generally does not need to be moved, and all the power swapping processes can be completed inside it, making it highly adaptable. Figure 1 The battery swapping stations shown are typically used in outdoor environments where battery swapping needs are frequent. These stations have separate battery storage areas and can be selected based on the application location.

[0041] like Figure 5As shown, the preferred wing door 2, when unfolded, has a height equal to or greater than the top height of station building 1. In this state, the wing door 2 is fitted against the top edge or side top of station building 1. The main purpose of the wing door 2 is to shield the area of ​​station building 1 and the heavy truck battery swapping entrance / exit 3 after heavy trucks enter the battery swapping area. When the drive mechanism is built-in and the wing door 2 is installed independently of station building 1, its rotational installation via the first fixing part 7 can cause gaps between the wing door 2 and station building 1 due to the thickness of common rotating installation structures such as hinged seats. This can lead to water leakage at the connection point. Therefore, this application restricts the wing door 2 to fitting against the top edge or side of station building 1 when unfolded, ensuring a better sealing effect after installation. Figure 5 As shown, a preferred configuration is that the hinged mounting point of the wing door 2 is located below the top surface. When rotating, the top of the wing door 2 can fit against the top edge or side of the station building 1, thereby ensuring a sealing effect.

[0042] With the above-mentioned wing door 2 configuration, a gap is formed between wing door 2 in its retracted state and the side wall of station building 1, as shown in the reference. Figure 5 (ii) This gap provides sufficient space for the installation of the first fixing part 7 and the second fixing part, and also provides space for the installation of the canopy.

[0043] The second fixing part is further extended from the interior or side wall of the station building 1 to connect with the wing door 2, so that the drive mechanism is set inside the station building 1. The drive mechanism is adapted to drive the second fixing part to move inside the station building 1 so that the wing door 2 can be adjusted and fixed. At least one side of the battery swapping entrance 3 is provided with a movable door 13. A transmission structure is provided inside the station building 1. The transmission structure is adapted to move in accordance with the opening / closing of the wing door 2 so that the movable door 13 opens / closes accordingly, and thus the battery swapping entrance 3 is opened / closed synchronously when the wing door 2 is opened / closed.

[0044] The meaning of the "simultaneous (synchronous)" opening / closing of the wing door 2 and the sliding door 13 can be simply summarized into the following three types: First, the wing door 2 cooperates with the sliding door 13 throughout its opening and closing process, that is, the sliding door 13 opens immediately when the wing door 2 opens, and the sliding door 13 is fully opened when the wing door 2 is fully opened; Second, the sliding door 13 opens immediately when the wing door 2 opens, and the sliding door 13 is fully opened before the wing door 2 is fully opened; Third, the sliding door 13 does not open temporarily when the wing door 2 opens, and the sliding door 13 begins to open after the wing door 2 has opened to a certain extent, and the sliding door 13 is fully opened when the wing door 2 is fully opened; Fourth, the sliding door 13 does not open temporarily when the wing door 2 opens, and the sliding door 13 begins to open after the wing door 2 has opened to a certain extent, and the sliding door 13 is fully opened before the wing door 2 is fully opened.

[0045] Since the sliding door 13 cannot effectively shield the wing door 2 if it is opened before the wing door 2 is opened to a certain extent, the third and fourth methods mentioned above can be preferred in actual situations.

[0046] The following presents two preferred implementation schemes for the transmission structure.

[0047] The first type of transmission structure includes a first link 11 hinged to the second fixed part and a second link 15 connected to the movable door 13. The first link 11 and the second link 15 are hinged together. The second link 15 restricts the sliding movement in the horizontal direction at both ends of the top of the battery exchange entrance 3. When the wing door 2 is opened, one end of the second fixed part connected to the station building 1 rises, and this end drives the other end of the first link 11 to move away from the battery exchange entrance 3, so that the movable door 13 leaves the battery exchange entrance 3.

[0048] Both sides of the battery swapping entrance / exit 3 are provided with sliding grooves 8. Inside the station building 1, a first sliding sleeve 12 corresponding to the sliding groove 8 is provided. The end of the second fixed part is provided with a hinge block. The hinge block passes through the sliding groove 8 and enters the inner cavity of the first sliding sleeve 12. The first sliding sleeve 12 has an avoidance groove on the side of the station building 1 away from the battery swapping entrance / exit 3. The hinge block forms a connecting protrusion through the avoidance groove, and the connecting protrusion is hinged to the first connecting rod 11. The top of the inner wall of the side of the station building 1 where the battery swapping entrance / exit 3 is provided with a second sliding sleeve 10 for restricting the movement of the second connecting rod 15. The second connecting rod 15 passes through the second sliding sleeve 10 and is fixedly connected to the sliding door 13. Figures 4 to 7 This diagram illustrates how the wing door 2 unfolds and retracts using this structure. (Refer to...) Figure 5 (I) and Figure 6 This is the open state of wing door 2. At this time, the first link 11 moves up and to the right, thereby causing the second link 15 to move to the right, and the sliding door 13 moves from the closed state (left side) to the open state (right side), thereby opening the sliding door 13. When wing door 2 is closed, the first link 11 moves down and to the left, thereby causing the second link 15 to move to the left, and the sliding door 13 closes.

[0049] The driving mechanism corresponding to the first transmission structure can be a lead screw slide, with slider 17 being the slide structure within the lead screw slide. The lead screw is driven to rotate by a motor, causing slider 17 to move up and down. In some embodiments, a winch 20 can also be used as the driving mechanism.

[0050] The second type of transmission structure includes a pulley and a rope for transmission. The corresponding drive mechanism can be a winch 20, with the rope wound around the winch 20. The end of the rope is connected to a slider 17. When the winch 20 begins winding, the rope pulls the slider 17 upwards. At this time, the wing door 2 can be opened by the rising slider 17. Simultaneously, the rope pulls the sliding door 13 open. See also... Figure 8The rope connects the sliding door 13 and the second fixed part. The pulley is used to change the direction of action. When the wing door 2 opens, the end of the second fixed part connected to the station building 1 rises, causing the rope to be pulled outward around the pulley to open the sliding door 13. At the same time, the reset component deforms. When the wing door 2 closes, the rope and the reset component reset. In this transmission structure, the return process of the wing door 2 requires action on the slider 17. This action can also be achieved by the wing door 2 itself hanging down, causing the slider 17 to move downward (of course, this process needs to be coordinated with the reverse rotation of the winch 20).

[0051] In the second transmission structure, the rope can be formed to cooperate with the sliding door 13 by means of bonding the action part 18 or knotting. The action part 19 can be provided on the sliding door 13, and the action part 18 can act on both sides of the action part 19. In this way, as the action part 18 opens or closes with the wing door 2, it can correspondingly act to move the sliding door 13, so that the sliding door 13 also opens or closes. With this configuration, the above-mentioned reset member is not a necessary structure.

[0052] Given the different opening and closing degrees of wing door 2 and sliding door 13, the opening and closing travel of wing door 2 is generally greater than that of sliding door 13. Therefore, adjusting the opening and closing timing of sliding door 13 to a certain extent helps to achieve better shielding effect for wing door 2 in rainy or other weather conditions (corresponding to the aforementioned meaning regarding the synchronous opening and closing of wing door 2 and sliding door 13). (Refer to...) Figure 3 As shown, rainwater falls vertically or at a certain angle during rainy weather. If the sliding door 13 is opened too early, before the wing door 2 has provided adequate shelter, rainwater may enter the station building 1 through the sliding door 13. This application addresses this by changing the timing of the opening. The opening timing is adjusted to a later position, meaning the sliding door 13 is only opened after the wing door 2 has expanded to a certain extent. This ensures that when the sliding door 13 opens, the wing door 2 already provides adequate shelter, thus preventing rainwater from entering the station building 1 throughout the entire process.

[0053] For example, corresponding to the first transmission structure, the second connecting rod 15 is configured to be telescopic, as shown in the reference. Figure 11During the opening and closing process of wing door 2, the first connecting rod 11 moves upward and to the right, correspondingly the second connecting rod 15 first extends to its limit and then pulls the sliding door 13 open, thus achieving the purpose of wing door 2 opening first, and then opening the sliding door 13 after it has opened to a certain extent. The second connecting rod 15 may include a first rod body 15a, a second rod body 15b, and a telescopic structure 15c for adjustment. The first rod body 15a and the second rod body 15b are sleeved together and their adjustable length is adjusted through the telescopic structure 15c. During installation, the adjustable distance between the two is first adjusted through the telescopic structure 15c as needed, thereby adjusting the opening timing of the sliding door 13. Of course, such adjustment also requires adjusting the position and length of the sliding door 13 to a certain extent to ensure that it can stably open and close the power exchange entrance / exit 3 accordingly when opening and closing, including but not limited to changing the length of the sliding door 13 and the initial position of the sliding door 13.

[0054] Figure 11 , Figure 12 In the middle, slider 17 is initially at the bottom, at which point the telescopic rod is in the retracted state. See [link / reference]. Figure 11 ① When wing door 2 opens, slider 17 rises, at which point the telescopic rod extends, but sliding door 13 does not move (see ②); wing door 2 continues to open, and sliding door 13 begins to move (see ③); wing door 2 is fully open, and sliding door 13 is fully open (see ④). During the return process, slider 17 descends, at which point the telescopic rod retracts first, and then closes with sliding door 13. Figure 12 For illustration of the second link 15, the first link 15a is fitted into the inner cavity of the second link 15b. The inner cavity of the second link 15b should include a limitation on the extension range of the first link 15a. Referring to the extension structure 15c, pins can be inserted at different positions to limit the extent to which the first link 15a can enter, thereby limiting the adjustable range. At the end of the inner cavity of the second link 15b, a structure is needed to prevent the first link 15a and the second link 15b from disengaging, such as a step for limitation.

[0055] The telescopic design of the second link 15 here corresponds to the aforementioned lag structure, specifically the third meaning in the above-mentioned "simultaneous opening and closing of wing door 2 and sliding door 13". Its function is to ensure that the sliding door 13 only begins to open after the wing door 2 has been open for a period of time (after the wing door 2 can form a shielding effect). Of course, in order to ensure that the sliding door 13 opens synchronously when the wing door 2 has finished opening, the synchronization timing can be adjusted by adjusting the telescopic length of the second link 15.

[0056] For the second type of transmission structure, refer to Figure 8Multiple actuating parts 18 can be evenly spaced on the rope, and multiple mating parts 19 can be correspondingly spaced on the sliding door 13. During mating, the wing door 2 needs to open a certain distance before the actuating parts 18 can move to the position where they engage with the mating parts 19, thus opening the sliding door 13. By increasing the spacing between the actuating parts 18, the spacing between the mating parts 19 is correspondingly increased. This results in a longer time required for the actuating parts 18 and mating parts 19 to engage, allowing the wing door 2 to open to a certain degree before opening the sliding door 13.

[0057] Regarding the specific configurations of the two transmission structures mentioned above, in the first transmission structure, the drive mechanism can be selected from various common drive devices such as lead screw slides, winches 20, cylinders, and electric cylinders, and the subsequent use of a lag structure is relatively simple. In the second transmission structure, winches 20 are preferred. When selecting other drive devices such as lead screw slides, it may be necessary to add other structures for coordination; therefore, using winches 20 is relatively convenient. The above can be freely selected according to actual needs.

[0058] like Figure 1 As shown, the first fixing part 7 includes at least two hinge seats fixedly installed on both sides of the battery swapping entrance / exit 3. The hinge seats are provided with connecting parts 6, which are connected to the wing door 2. The connecting parts 6 are adapted to increase the distance between the wing door 2 and the side wall of the station building 1 after installation. The connecting parts 6 are located at a set height below the top surface of the wing door 2 so that the top of the wing door 2 in the unfolded state covers the gap formed between the wing door 2 and the station building 1.

[0059] like Figure 5 (a) The heavy-duty truck battery swapping station also includes hoisting equipment. This hoisting equipment is used to lift the batteries 4 inside the station building 1 from the battery swapping entrance / exit 3 to the outside, and is suitable for lowering the batteries 4 and installing them onto the battery swapping truck. Simultaneously, the hoisting equipment is suitable for removing the depleted batteries 4 from the truck and hoisting them to a designated position. The hoisting equipment has a traveling structure 21 installed on the ceiling inside the station building 1. The traveling structure 21 is suitable for sending the outer end of the hoisting equipment out of the battery swapping entrance / exit 3 after the wing door 2 is opened. The hoisting equipment is a basic piece of equipment for the battery swapping station, and this application does not impose additional limitations on it. It generally includes a hoisting guide rail 14, a clamping part for gripping, and other structures.

[0060] Reference Figure 9 , Figure 10 A folding canopy 16 is installed in the middle of the side of wing door 2. The other side of the folding canopy 16 is fixedly installed on the station building wall. When unfolded, the folding canopy 16 is fan-shaped. When wing door 2 is retracted, the folding canopy 16 is stored in the gap formed between the station building wall and wing door 2. The two sides of the folding canopy 16 can be directly fixed by adhesive, screws, etc. The folding canopy is intended to increase the shielding effect on the side of the power swapping area. The canopy installed on the side should not be too large, and should not exceed a certain size in the design. Figure 2The area of ​​the connecting part 6 shown.
