Description

Technical Field

[0001] This application relates to the field of battery swapping, and in particular to a bridge device and a battery swapping station. Background Technology

[0002] Energy conservation and emission reduction are key to the sustainable development of the automotive industry, and electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of this sustainable development. For electric vehicles, battery technology is a crucial factor in their development.

[0003] When a vehicle's battery is about to run out after a period of time, it needs to enter a battery swapping station to have its battery removed and replaced. In related technologies, there is a risk of the vehicle skidding when passing over the bridge device at the battery swapping station, which affects the reliability of battery swapping. Summary of the Invention

[0004] In view of the above problems, this application provides a bridge crossing device and a battery swapping station. The bridge crossing device is used to support vehicles and can ensure the reliability of vehicles when the bridge crossing device passes.

[0005] In a first aspect, this application provides a battery casing, including a bridge device, comprising: a guiding assembly including two or more guide members spaced apart along a first direction; a supporting assembly disposed on one side of the guiding assembly in a second direction, the supporting assembly including a support member and a traveling member connected to each other, the traveling member being movably disposed on the guide member, the support member being used to support a vehicle; a driving assembly connected to the supporting assembly, the driving assembly being used to drive the supporting assembly to move along the extension direction of the guide member; and a limiting member disposed on the side of the support member facing the guiding assembly; wherein the bridge device has a first state and a second state; in the first state, the limiting member is separated from the guide member, and the traveling member has a degree of freedom of movement along the extension direction of the guide member; in the second state, the limiting member is in contact with the guide member, the limiting member restricting the movement of the traveling member along the extension direction, and the first direction, the second direction, and the extension direction intersect each other.

[0006] One embodiment of this application provides a bridge-crossing device including a guiding component, a supporting component, a driving component, and a limiting component. The supporting component supports a vehicle through its supporting member. The guiding component supports and guides the supporting component, and the driving component drives the supporting component to move along the guiding member to facilitate vehicle passage and battery replacement. The limiting component allows the bridge-crossing device to have a first state and a second state. In the first state, the limiting component is separated from the guiding member, and the traveling component can move along the extension direction of the guiding member to make way for the vehicle, while the supporting member ensures the vehicle's battery swapping needs. When the vehicle passes through the bridge-crossing device before and after battery swapping, the bridge-crossing device can be in the second state, where the limiting component contacts the guiding member. The limiting component restricts the traveling component from moving along the extension direction, thereby reducing the probability of the vehicle skidding when passing through the bridge-crossing device. Furthermore, when the bridge-crossing device switches to the second state, the limiting component contacts the guiding member and can share the load of the battery-swapping vehicle with the traveling component, thus distributing the load, reducing the load on the traveling component, and ensuring the reliability of battery swapping.

[0007] In some embodiments, the size of the support protruding from the travel member along the second direction toward the side where the guide is located is adjustable; in the first state, the size of the support protruding from the travel member along the second direction toward the side where the guide is located is d1, and in the second state, the size of the support protruding from the travel member along the second direction toward the side where the guide is located is d2, wherein d2 < d1.

[0008] One embodiment of the bridge crossing device provided in this application, through the above-described configuration, enables the load-bearing device to switch between a first state and a second state by changing the size of the traveling member in the second direction. This simplifies the structure and facilitates the switching of the load-bearing device's state.

[0009] In some embodiments, in the second state, the dimension of the support member protruding from the support member along the second direction and toward the side where the guide member is located is d2, and the dimension of the limit member protruding from the support member along the second direction and toward the side where the guide member is located is d3, wherein d2 = d3, and the limit member and the support member jointly support the support member.

[0010] The bridge crossing device provided in one embodiment of this application, through the above-described configuration, enables the limiting member in the second state to not only restrict the movement of the traveling member along the extension direction of the guide member, reducing the probability of lateral displacement of the vehicle when the bridge crossing device passes, but also to jointly support the support member and the vehicle above it with the traveling member, reducing the pressure borne by the individual traveling member, reducing wear, and improving the reliability of the bridge crossing device.

[0011] In some embodiments, the traveling member and the limiting member are responsive to the weight of the vehicle carried by the supporting member to switch the bridge crossing device from a first state to a second state.

[0012] Through the above configuration, the bridge-crossing device can respond to the vehicle's gravity. The limiting and traveling components can be triggered by the vehicle's gravity, causing the bridge-crossing device to switch from a first state to a second state. After the vehicle passes over the bridge-crossing device, the device can switch back to the first state from the second state, ensuring the timing of the switching between states. For example, when the vehicle's wheels are on the load-bearing component, the bridge-crossing device is in the second state, ensuring stable vehicle operation and preventing sideslip, with the limiting and traveling components sharing the vehicle's load. When the vehicle straddles the bridge-crossing device, if neither its front nor rear wheels are on the load-bearing component, the bridge-crossing device can be in the first state. The load-bearing component can move relative to the guide component, moving to the vehicle chassis position to facilitate battery replacement. After the battery replacement is complete, the load-bearing component moves relative to the guide component to under the vehicle chassis, the vehicle starts moving, and when the rear wheels are on the load-bearing component, the bridge-crossing device switches back to the second state to prevent sideslip.

[0013] In some embodiments, the traveling component includes a traveling body, an elastic element, and an elastic mounting element. The elastic element is connected between the traveling body and the elastic mounting element. One of the traveling body and the elastic mounting element is connected to a support element. The elastic element is compressible to allow the bridge crossing device to switch between a first state and a second state.

[0014] With the above configuration, the traveling body and the guide can work together to move the load-bearing component relative to the guide component. One of the traveling body and the elastic mounting component is connected to the support component. The elastic component is connected between the traveling body and the elastic mounting component and is compressible, allowing the overall length of the traveling component in the second direction to be adjustable, and also allowing the relative position of the traveling body and the support component in the second direction to be adjustable. This enables the adjustable size of the traveling component protruding from the support component in the second direction, ensuring smooth switching between the first and second states of the bridge crossing device, reducing the probability of vehicle sideslip when the bridge crossing device passes, and ensuring the reliability of battery swapping.

[0015] In some embodiments, the walking body includes a support frame and a walking wheel. The support frame is disposed on at least one of a support member and an elastic mounting member. The elastic member is connected to the support frame and the elastic mounting member. The walking wheel is rotatably connected to the support frame.

[0016] One embodiment of the bridge-crossing device provided in this application, through the above-described configuration, enables the traveling body to roll in cooperation with the guide member via its traveling wheels, ensuring smooth movement of the entire load-bearing component relative to the guide member. Furthermore, the aforementioned configuration of the elastic member ensures that when the vehicle travels towards the load-bearing component and gravity acts on it, the elastic member is compressed, causing a change in the relative position of the bracket and the elastic mounting member. The dimension of the traveling member protruding from the support member along the second direction towards the guide member decreases, facilitating the switching of the bridge-crossing device between the first and second states.

[0017] In some embodiments, along a first direction, the elastic element is telescopically arranged, the bracket includes a first frame, a second frame and a rotating shaft, the first frame and the second frame are arranged crosswise, the rotating shaft is inserted into the area where the first frame and the second frame overlap, at least one of the first frame and the second frame has a degree of rotational freedom relative to the rotating shaft, the first frame and the second frame are respectively rotatably connected to a traveling wheel on the side facing the guide assembly, and the first frame and the second frame are respectively provided with an elastic element on the side facing away from each other in the extension direction.

[0018] One embodiment of this application provides a bridge crossing device in which the support adopts the above-described structure. In the first state, when the load-bearing component is in a non-load-bearing state and no external force is applied, each elastic member pushes the first end of the corresponding first frame and the third end of the second frame to move closer to each other. The second end and the fourth end move closer to each other, such that the traveling member protrudes from the support member by a dimension d1 along the second direction and toward the side where the guide member is located. When the vehicle moves onto the load-bearing component, the load-bearing component is in a load-bearing state. Under the pressure of the vehicle's gravity, the elastic members on both sides are compressed, and the first and third ends move away from each other, as do the second and fourth ends. In the second direction, the height of the traveling member in the second state is reduced compared to the first state. Correspondingly, in the second state, the traveling member protrudes from the support member along the second direction and toward the side where the guide member is located by a dimension d2, where d2 is less than d1. This allows the bridge crossing device to quickly respond to the weight of the vehicle carried by the support member when the vehicle travels onto the load-bearing component, causing the limiting member to contact the guide member to restrict the traveling member from moving along the extension direction, effectively reducing the probability of the vehicle skidding when passing through the bridge crossing device.

[0019] In some embodiments, the elastic mounting member includes a guide rod and a stop member. The extension direction of the guide rod intersects the extension direction of the rotating shaft. Along the extension direction of the guide rod, the first frame and the second frame are respectively provided with an elastic member and a stop member at their opposite ends. One end of the elastic member abuts against the stop member and the other end abuts against the corresponding first frame or second frame.

[0020] One embodiment of this application provides a bridge crossing device in which the elastic mounting member adopts the above-described structure, which can ensure the connection relationship between the bridge crossing device and the first frame and the second frame, and facilitates the switching of the bridge crossing device between the first state and the second state.

[0021] In some embodiments, the pivot extends along a first direction and protrudes from the first frame and the second frame, and the pivot is detachably connected to the support, the first bracket and the second bracket.

[0022] One embodiment of the bridge crossing device provided in this application, through the above-described configuration, allows the rotating shaft to be disassembled from the support, and the first frame and the second frame to be disassembled and separated when the traveling component needs to be disassembled, by means of pulling or other methods. This enables the entire assembly consisting of the first frame and the second frame, along with the traveling wheels connected to them, to be separated from the support, facilitating lateral movement of the traveling component and its removal from under the support for maintenance and replacement.

[0023] In some embodiments, the elastic mounting member is fixedly disposed on the support member, the walking body is connected to the elastic mounting member, the walking body protrudes from the elastic mounting member in a second direction toward the side where the guide component is located, and the elastic member is compressible in the second direction to adjust the size of the walking body protruding from the elastic mounting member in the second direction.

[0024] One embodiment of this application provides a bridge-crossing device. Through the aforementioned configuration, when the supporting member is subjected to external force, such as when a vehicle passes and presses against it, the vehicle's gravity is transmitted to the elastic member through the elastic mounting member, causing the elastic member to be compressed. The traveling body moves relative to the elastic mounting member towards the side where the supporting member is located along the second direction, reducing the size of the traveling body protruding from the elastic mounting member in the second direction, i.e., adjusting the size of the traveling body protruding from the elastic mounting member in the second direction. This allows the bridge-crossing device to switch from a first state to a second state, where the limiting member and the guide member are in contact, and the limiting member restricts the movement of the traveling body along the extension direction. When the vehicle passes and the external force is released, the elastic member returns to its original deformation, becoming longer, pushing the traveling body to move away from the supporting member relative to the elastic mounting member in the second direction. The bridge-crossing device switches from the second state to the first state, where the limiting member and the guide member are separated, and the traveling body has a degree of freedom of movement along the extension direction of the guide member, thus still meeting the functional requirements of the bridge-crossing device.

[0025] In some embodiments, the elastic mounting member is provided with a clearance space and a plug hole, the walking body is disposed in the clearance space, the two ends of the walking body in the first direction are respectively plugged into the plug hole and supported by the elastic mounting member, and each end of the walking body in the first direction is provided with an elastic member.

[0026] One embodiment of the bridge-crossing device provided in this application, through the above-described configuration, utilizes the clearance space to accommodate the traveling body, allowing both ends of the traveling body in the first direction to be inserted into the insertion holes of the elastic mounting members, thus ensuring the reliability of the elastic mounting members' support for the traveling body. By providing elastic members at each end of the traveling body in the first direction, the stability of the bridge-crossing device when switching between the first and second states is ensured.

[0027] In some embodiments, the walking component further includes a stroke adjustment component, which is inserted into the resilient mounting component along a second direction. The stroke adjustment component extends into the insertion hole and abuts against the walking body. The size of the stroke adjustment component inserted into the insertion hole in the second direction is adjustable.

[0028] The bridge crossing device provided in one embodiment of this application, through the above-described configuration, can adjust the initial compression of the elastic member by adjusting the depth of the stroke adjusting member inserted into the insertion hole along the second direction, so as to meet the load-bearing requirements of the bridge crossing device for different battery swapping vehicles.

[0029] In some embodiments, the support member includes a plurality of support plates distributed along the arrangement direction of the guide member, and each support plate is connected to a traveling member.

[0030] One embodiment of the bridge-crossing device provided in this application, through the above-described configuration, can reduce the molding difficulty of the support component and ensure the flatness of its surface used to support the vehicle. This avoids warping deformation caused by excessive area during processing, preventing excessive local pressure when the vehicle is held in place, and thus improving the reliability of the bridge-crossing device.

[0031] In some embodiments, connectors are provided between the plurality of support plates.

[0032] In some embodiments, the drive assembly includes a drive member, a transmission wheel, and a traction member. The traction member is wound around the transmission wheel, the drive member is connected to the transmission wheel and drives the transmission wheel to rotate, and the load-bearing assembly is connected to the traction member. The traction member includes one of a transmission belt and a transmission chain.

[0033] With the above configuration, the drive component can drive the transmission wheel to rotate, which in turn drives the traction component to move along the extension direction of the guide component. This, in turn, causes the support component to move along the extension direction. The reciprocating movement of the load-bearing assembly in the extension direction can be achieved by driving the drive component in either the forward or reverse direction.

[0034] In some embodiments, the drive assembly further includes a buffer connected to the traction member, the buffer being at least partially telescopic in the extension direction of the guide member.

[0035] By setting up buffer components, it is possible to effectively prevent the impact load on the traction components from damaging the drive assembly when the battery swapping vehicle passes by.

[0036] In some embodiments, the support member is provided with buffer members at both ends of the guide member in the extension direction.

[0037] The above configuration ensures that the load-bearing components have buffers to provide cushioning when moving forward and backward in the extension direction of the guide, which helps to meet the buffering requirements of the impact load on the chain when the battery swapping vehicle passes through.

[0038] In some embodiments, the bridge device further includes a support base, and the guide assembly is provided with support bases on both sides of the first direction, and the guide member located at the edge of the first direction is connected to the support base.

[0039] With the above setup, the battery swapping vehicle can be supported by the support base, and the support base can also provide support and protection for the installation of the guide components.

[0040] In some embodiments, the support base is provided with a recessed portion recessed along a first direction, and a guide portion located at the edge in the first direction extends into the recessed portion.

[0041] In some embodiments, the support assembly further includes a guide wheel assembly connected to the support member, the guide wheel assembly abutting against one side surface of the guide member in a first direction.

[0042] The above configuration allows the guide wheel assembly to limit the movement of the load-bearing component and the guide member in the first direction. Furthermore, it ensures smooth movement of the load-bearing component relative to the guide assembly.

[0043] Secondly, this application provides a battery swapping station, including the aforementioned bridge device.

[0080] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0081] It should be noted that, unless otherwise stated, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by those skilled in the art to which the embodiments of this application pertain.

[0082] In the description of the embodiments of this application, the technical terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0083] Furthermore, technical terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise explicitly defined.

[0084] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0085] In the description of the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0086] With increasing global attention to environmental protection and sustainable development, new energy vehicles have been widely promoted and applied as an important alternative to traditional fuel vehicles. Battery swapping stations for new energy vehicles, as an important energy supply facility, are mainly divided into ground-mounted swapping stations and trench / pit-type swapping stations. Ground-mounted swapping stations are relatively simple to construct, requiring less surface construction. Trench / pit-type swapping stations, on the other hand, place the swapping equipment underground by excavating deep into the ground, reducing surface space occupation and allowing for smoother vehicle entry and exit.

[0087] Battery swapping stations are crucial for the popularization and development of new energy vehicles. Compared with charging, battery swapping offers advantages such as faster battery replacement and reduced user waiting time, effectively addressing range anxiety in the new energy vehicle market. Furthermore, battery swapping stations allow for centralized management and maintenance of batteries, extending battery lifespan and reducing user costs.

[0088] In battery swapping technology using pits or trenches, vehicles need to enter the swapping station for battery removal and replacement when their power is depleted. Currently, the bridging devices used in these stations have several problems. The bridging plates are typically supported by rollers, and the sliding friction between the rollers and the support rails is very low. This makes the bridging plates prone to sideslip perpendicular to the vehicle's direction of travel during the swapping process. During battery swapping, the vehicle needs precise positioning to ensure successful battery replacement. Sideslip of the bridging plates can cause vehicle displacement, increasing the difficulty of the swapping process and posing significant safety risks, such as improper battery installation and vehicle imbalance. Furthermore, in these swapping stations, the bridging devices also bear the weight of the vehicle via the roller track, resulting in a significant load and a risk of crushing. All of these factors affect the reliability of the battery swapping process.

[0089] Research has found that during vehicle battery swapping, the lateral slippage perpendicular to the vehicle's direction of travel can be limited by increasing the friction between the bridge device and the support rail. Therefore, this application provides a bridge device including a guide assembly, a load-bearing assembly, a drive assembly, and a limiting member. The guide assembly includes two or more guide members spaced apart along a first direction. The load-bearing assembly is disposed on one side of the guide assembly in a second direction, and includes a connected support member and a traveling member. The traveling member is movably disposed on the guide member, and the support member supports the vehicle. The drive assembly is connected to the load-bearing assembly and drives the load-bearing assembly to move along the extension direction of the guide member. The limiting member is disposed on the side of the support member facing the guide assembly. The bridge device has a first state and a second state. In the first state, the limiting member is separated from the guide member, and the traveling member has a degree of freedom of movement along the extension direction of the guide member. In the second state, the limiting member is in contact with the guide member, and the limiting member restricts the movement of the traveling member along the extension direction. The first direction, the second direction, and the extension direction intersect each other. The limiting component allows the bridge crossing device to have two states: a first state and a second state. In the first state, the limiting component and the guide component are separated, allowing the traveling component to move along the extension direction of the guide component, ensuring the vehicle's battery swapping needs are met. When the vehicle passes over the bridge crossing device before and after battery swapping, the device can be in the second state, where the limiting component contacts the guide component. The limiting component restricts the traveling component's movement along the extension direction of the guide component, thereby reducing the probability of the vehicle skidding when passing over the bridge crossing device. Furthermore, when the bridge crossing device switches to the second state, the limiting component contacts the guide component, allowing it to share the load of the battery swapping vehicle with the traveling component, thus distributing the load and reducing the load on the traveling component, ensuring the reliability of battery swapping.

[0090] The bridge crossing device and battery swapping station disclosed in this application can be used, but are not limited to, for replacing batteries of electrical equipment. The electrical equipment includes vehicles, which can be fuel vehicles, natural gas vehicles, or new energy vehicles. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended vehicles, etc.

[0091] The following explanation uses a vehicle as an example of an electrical appliance.

[0092] like Figure 1 As shown, vehicle 1 is equipped with battery 100, which may be located at the bottom, front, or rear of vehicle 1. Battery 100 can be used to power vehicle 1; for example, battery 100 can serve as the operating power source for vehicle 1.

[0093] Vehicle 1 may also include controller 200 and motor 300. Controller 200 is used to control battery 100 to supply power to motor 300, for example, for the power needs of vehicle 1 during start-up, navigation and driving.

[0094] In some embodiments of this application, the battery 100 can not only serve as the operating power source for the vehicle 1, but also as the driving power source for the vehicle 1, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1.

[0095] In some embodiments, the battery 100 can be snapped onto the chassis of the vehicle 1 via a snap-fit ​​structure.

[0096] like Figure 2 As shown, battery 100 can refer to a single physical module comprising one or more battery cells 120 to provide higher voltage and capacity.

[0097] In some embodiments, the battery 100 may be a battery pack.

[0098] As an example, battery 100 includes a housing 110 and battery cells 120, with battery cells 120 housed within the housing 110.

[0099] The housing 110 can be a component for accommodating the battery cell 120. The housing 110 provides space for accommodating the battery cell 120, and the housing 110 can adopt various structures.

[0100] In some embodiments, the housing 110 may include a first housing portion 110a and a second housing portion 110b, which overlap each other, and together define a receiving space for accommodating the battery cell 120. The second housing portion 110b may be a hollow structure with one open end, and the first housing portion 110a may be a plate-like structure, covering the open side of the second housing portion 110b to form a housing 110 with a receiving space. Alternatively, both the first housing portion 110a and the second housing portion 110b may be hollow structures with one open side, with the open side of the first housing portion 110a covering the open side of the second housing portion 110b to form a housing 110 with a receiving space. Of course, the first housing portion 110a and the second housing portion 110b may be of various shapes, such as cylinders, cuboids, etc.

[0101] Assuming that the first box part 110a covers the top of the second box part 110b, the first box part 110a can also be called the upper box cover, and the second box part 110b can also be called the lower box 110.

[0102] In battery 100, there can be one or more battery cells 120. If there are multiple battery cells 120, they can be connected in series, in parallel, or in a mixed manner. A mixed connection means that multiple battery cells 120 are connected in both series and parallel.

[0103] Multiple battery cells 120 can be directly connected in series, in parallel, or in a mixed manner, and then the whole composed of multiple battery cells 120 can be housed in the housing 110; of course, multiple battery cells 120 can also be connected in series, in parallel, or in a mixed manner to form a battery module, and multiple battery modules can then be connected in series, in parallel, or in a mixed manner to form a whole, and housed in the housing 110.

[0104] like Figures 3 to 6 As shown, one embodiment of this application provides a bridge-crossing device 400 for replacing the battery 100 of the aforementioned electrical device, such as a vehicle. The bridge-crossing device 400 includes a guide assembly 10, a load-bearing assembly 20, a drive assembly 30, and a limiting member 40.

[0105] The guide assembly 10 includes two or more guide members 11 spaced apart along a first direction Y. A support assembly 20 is disposed on one side of the guide assembly 10 in a second direction Z. The support assembly 20 includes a connected support member 21 and a traveling member 22. The traveling member 22 is movably disposed on the guide member 11, and the support member 21 supports the vehicle 1. A drive assembly 30 is connected to the support assembly 20 and drives the support assembly 20 to move along the extending direction X of the guide member 11. A limiting member 40 is disposed on the side of the support member 21 facing the guide assembly 10.

[0106] The bridge crossing device 400 has a first state and a second state, such as... Figure 5 As shown, in the first state, the limiting member 40 is separated from the guide member 11, and the traveling member 22 has a degree of freedom of movement along the extending direction X of the guide member 11. Figure 6 As shown, in the second state, the limiting member 40 is in contact with the guide member 11, and the limiting member 40 restricts the movement of the traveling member 22 along the extension direction X. The first direction Y, the second direction Z, and the extension direction X intersect each other. The setting of the limiting member 40 allows the bridge crossing device 400 to have a first state and a second state. In the first state, the limiting member 40 is separated from the guide member 11, and the traveling member 22 can move along the extension direction X of the guide member 11 to ensure the battery swapping needs of the vehicle 1. When the vehicle 1 travels through the bridge crossing device 400 before and after battery swapping, the bridge crossing device 400 can be in the second state, so that the limiting member 40 is in contact with the guide member 11, and the limiting member 40 restricts the movement of the traveling member 22 along the extension direction. The first direction Y, the second direction Z, and the extension direction X intersect each other.

[0107] The guide component 10 may include two, three, or more guide elements 11. Two or more guide elements 11 may be spaced apart from each other in the first direction Y, optionally spaced apart and evenly spaced, or optionally arranged parallel to each other.

[0108] Each guide 11 may include either a guide rail or a guide groove disposed on the base.

[0109] When the bridge device 400 is used to swap the battery for vehicle 1, the first direction Y can be understood as the direction of travel of vehicle 1.

[0110] The support component 20 is disposed on one side of the guide component 10 in the second direction Z. The second direction Z can be understood as the height direction of the vehicle 1, or the arrangement direction of the chassis and roof of the vehicle 1. The second direction Z intersects with the first direction Y, and can optionally be perpendicular to the first direction Y. The extension direction X of the guide component 11 can be the width direction or the left-right direction of the vehicle 1, or can be understood as the length direction of the guide component 11 itself. The extension direction X intersects with the first direction Y and the second direction Z, and can optionally be perpendicular to each other.

[0111] The movable configuration between the carrier component 20 and the guide 11 includes a scrolling configuration and a sliding configuration, with the scrolling configuration being optional.

[0112] The traveling component 22 of the load-bearing assembly 20 includes structures such as traveling wheels and sliders. The supporting component 21 includes structures such as support plates and support frames, used to support the vehicle 1.

[0113] The drive assembly 30 can be fixedly or detachably connected to the support assembly 20. The drive assembly 30 and the support assembly 20 can be connected by welding, fastener connection, or sleeve connection. The drive assembly 30 can be connected to the support member 21 of the support assembly 20.

[0114] The drive assembly 30 includes a motor that drives the chain to move, thereby driving the load-bearing assembly 20 to move along the guide assembly 10. Of course, the drive assembly 30 may also include a telescopic cylinder, a gear rack, a worm gear, or other structures that can achieve linear drive, so as to drive the load-bearing assembly to move along the extension direction X of the guide 11.

[0115] The limiting member 40 can be fixedly or detachably connected to the support member 21 on the side facing the guide assembly 10 in the second direction Z.

[0116] The first state of the bridge crossing device 400 may include a state where the vehicle 1 has not entered, the traveling member 22 has a degree of freedom of movement along the extension direction X of the guide member 11, and the limiting member 40 is separately disposed from the guide member 11. The second state may include a state where the vehicle 1 enters, or when the pressure borne by the load-bearing component exceeds a predetermined threshold, the load-bearing component 20 is in a stopped braking state relative to the guide member 10. At this time, the limiting member 40 is in contact with the guide member 11, thereby restricting the movement of the traveling member 22 along the extension direction X of the guide member 11, and sharing the load borne by the support member with the traveling member.

[0117] In the second state, the limiting member 40 can achieve contact with the guide member 11 by adjusting its own length. Of course, in the second state, the limiting member 40 can also be moved relative to the guide member 11 and made into contact with the guide member 11 by at least a part of the carrying component 20, so as to restrict the movement of the traveling member 22 along the extension direction X.

[0118] One embodiment of this application provides a bridge crossing device 400. In use, the load-bearing component 20 supports the vehicle 1 through its support member 21, the guide component 10 supports and guides the load-bearing component 20, and the drive component 30 drives the load-bearing component 20 to move along the guide member 11 to enable the passage of the vehicle 1 and the replacement of the battery 100. The setting of the limiting member 40 enables the bridge crossing device 400 to have a first state and a second state. In the first state, the limiting member 40 is separated from the guide member 11, and the traveling member 22 can move along the extension direction X of the guide member 11 to make way for the vehicle 1 and ensure the battery swapping needs of the vehicle 1. When the vehicle 1 passes through the bridge crossing device 400 before and after battery swapping, the bridge crossing device 400 can be in the second state, so that the limiting member 40 is in contact with the guide member 11. The limiting member 40 restricts the movement of the traveling member 22 along the extension direction X, thereby reducing the probability of the vehicle 1 skidding when passing through the bridge crossing device 400. Furthermore, when the bridge crossing device 400 switches to the second state, the limiting member 40 contacts the guide member 11, and can share the load of the battery swapping vehicle 1 with the traveling member 22, thereby reducing the load borne by the traveling member 22 and ensuring the reliability of battery swapping.

[0119] Continue reading Figures 3 to 6 As shown, in some optional embodiments, the bridge crossing device 400 provided in one embodiment of this application has an adjustable size for the traveling member 22 protruding from the support member 21 along the second direction Z toward the side where the guide member 11 is located. In a first state, the size of the traveling member 22 protruding from the support member 21 along the second direction Z toward the side where the guide member 11 is located is d1. In a second state, the size of the traveling member 22 protruding from the support member 21 along the second direction Z toward the side where the guide member 11 is located is d2, where d2 < d1.

[0120] Using the plane containing the bottom surface of the support member 21 facing the guide member 11 in the second direction Z as the reference plane MM, in the first state, the vertical distance from the lowest point of the traveling member 22 on the side facing away from the support member 21 in the second direction Z to the reference plane MM is d1. In the second state, the size of the traveling member 22 in the second direction Z is reduced, and the vertical distance from the lowest point of the traveling member 22 on the side facing away from the support member 21 in the second direction Z to the reference plane MM is d2, where d2 < d1. In the first state, since the size of the limiting member 40 protruding from the reference plane MM in the second direction Z is smaller than the size of the traveling member 22 protruding from the reference plane MM in the second direction Z, it can be ensured that the limiting member 40 is separated from the guide member 11 in the first state. In the second state, the size of the limiting member 40 protruding from the reference plane MM in the second direction Z can be greater than or equal to the size of the traveling member 22 protruding from the reference plane MM in the second direction Z, thereby allowing the limiting member 40 to contact the guide member 11 and restrict the traveling member 22 from moving along the extension direction X of the guide member 11.

[0121] The bridge crossing device 400 provided in one embodiment of this application, through the above-described configuration, enables the load-bearing device to switch between the first state and the second state by changing the size of the traveling member 22 in the second direction Z. The structure is simplified and facilitates the switching of the load-bearing device's state.

[0122] Continue reading Figures 3 to 6 As shown, in some optional embodiments, in a second state, the bridge crossing device 400 provided in one embodiment of this application has a dimension d2 protruding from the support member 21 along the second direction Z toward the side where the guide member 11 is located, and a dimension d3 protruding from the support member 21 along the second direction Z toward the side where the guide member 11 is located, where d2 = d3, and the limit member 40 and the walking member 22 jointly support the support member 21.

[0123] Optionally, the plane containing the bottom surface of the support member 21 facing the guide member 11 in the second direction Z can be used as the reference plane MM. In the second state, the vertical distance from the lowest point of the traveling member 22 on the side away from the support member 21 in the second direction Z to the reference plane MM is d2. The vertical distance from the lowest point of the limiting member 40 on the side away from the support member 21 in the second direction Z to the reference plane MM is d3, where d2 = d3. Alternatively, it can be understood that in the second state, the dimension by which the traveling member 22 protrudes from the reference plane MM in the second direction Z is the same as the dimension by which the limiting member 40 protrudes from the reference plane MM.

[0124] One embodiment of this application provides a bridge crossing device 400, which, through the above-described configuration, enables the limiting member 40 in the second state to not only restrict the movement of the traveling member 22 along the extension direction X of the guide member 11, reducing the probability of the vehicle 1 shifting laterally when the bridge crossing device 400 passes through, but also to jointly support the support member 21 and the vehicle 1 above it with the traveling member 22, reducing the pressure borne by the individual traveling member 22, reducing wear, and improving the reliability of the bridge crossing device 400.

[0125] In some alternative embodiments, the bridge crossing device 400, the traveling member 22 and the limiting member 40 provided in one embodiment of this application can switch the bridge crossing device 400 from a first state to a second state in response to the gravity of the vehicle 1 carried by the supporting member 21.

[0126] The ability of the traveling member 22 and the limiting member 40 to respond to the weight of the vehicle 1 carried by the supporting member 21 can be understood as follows: when the vehicle 1 travels above the supporting component 20 and contacts its supporting member 21, at least part of the weight of the vehicle 1 presses on the supporting member 21. Under its gravity, the supporting member 21 bears a force along the second direction Z, and the bridge crossing device 400 switches from the first state to the second state. That is, the bridge crossing device 400 can be triggered by the action of the vehicle 1 to switch from the first state to the second state. After the vehicle 1 passes over the bridge crossing device 400, the bridge crossing device 400 can switch back from the second state to the first state.

[0127] One embodiment of this application provides a bridge-crossing device 400. Through the aforementioned configuration, the bridge-crossing device 400 can respond to the gravity of the vehicle 1. The limiting member 40 and the traveling member 22 can be triggered by the gravity of the vehicle 1, causing the bridge-crossing device 400 to switch from a first state to a second state. After the vehicle 1 passes through the bridge-crossing device 400, the bridge-crossing device 400 can switch back to the first state from the second state, ensuring the timing of the bridge-crossing state switching. For example, when the wheels of the vehicle 1 are on the load-bearing component 20, the bridge-crossing device 400 is in the second state, ensuring the smooth operation of the vehicle 1 and preventing sideslip. The limiting member 40 and the traveling member 22 share the vehicle's load. When the vehicle 1 straddles the bridge-crossing device 400, if its front and rear wheels are not on the load-bearing component 20, the bridge-crossing device 400 can be in the first state. The load-bearing component 20 can move relative to the guiding component 10, making way for the vehicle 1's chassis position, facilitating the replacement of the vehicle 1's battery 100. After the battery 100 is replaced, the load-bearing component 20 moves relative to the guide component 10 to the chassis of the vehicle 1, the vehicle 1 starts and continues to move. When the rear wheel is on the load-bearing component 20, the bridge crossing device 400 switches to the second state again to prevent the vehicle 1 from skidding.

[0128] Optionally, when the limiting member 40 is a telescopic member, the response to the gravity of the vehicle 1 includes: collecting pressure information of the vehicle 1 acting on the bearing component 20 through a collector; when the collected pressure information is within a preset threshold range, controlling the limiting member 40 to extend, so that the limiting member 40 contacts the guide member 11; when the collected pressure information exceeds the preset threshold range, controlling the limiting member 40 to shorten and separate from the guide member 11.

[0129] Of course, this is an optional implementation. In some embodiments, the size of the supporting member 21 protruding from the guide member 11 along the second direction Z can be changed by the force of the vehicle 1. The following will describe the bridge crossing device 400 of the optional embodiment of this application in this way.

[0130] like Figures 7 to 13 As shown, in some optional embodiments, the walking component 22 includes a walking body 221, an elastic component 222, and an elastic mounting component 223. The elastic component 222 is connected between the walking body 221 and the elastic mounting component 223. One of the walking body 221 and the elastic mounting component 223 is connected to the support component 21. The elastic component 222 is compressible to allow the bridge crossing device 400 to switch between a first state and a second state.

[0131] The walking body 221 is used to contact and engage with the guide member 11 of the guide assembly 10 and is able to move along the guide member 11. The elastic mounting member 223 is used to mount the elastic member 222. The elastic member 222 includes a structure that can deform under pressure, such as a spring or rubber product.

[0132] One embodiment of this application provides a bridge crossing device 400, which, through the above-described configuration, enables the traveling body 221 to cooperate with the guide member 11 to drive the load-bearing component 20 to move relative to the guide member 10. One of the traveling body 221 and the elastic mounting member 223 is connected to the support member 21. The elastic member 222 is connected between the traveling body 221 and the elastic mounting member 223 and is compressible, allowing the overall length of the traveling member 22 in the second direction Z to be adjustable, and also allowing the relative position of the traveling body 221 and the support member 21 in the second direction Z to be adjustable. This achieves adjustable dimensions of the traveling member 22 protruding from the support member 21 in the second direction Z, ensuring the bridge crossing device 400 meets the state switching requirements between the first and second states, reducing the probability of the vehicle 1 skidding when passing through the bridge crossing device 400, and ensuring the reliability of battery swapping.

[0133] In some alternative embodiments, the walking body 221 includes a support 2211 and a walking wheel 2212. The support 2211 is disposed on at least one of the support member 21 and the elastic mounting member 223. The elastic member 222 is connected to the support 2211 and the elastic mounting member 223. The walking wheel 2212 is rotatably connected to the support 2211.

[0134] The traveling wheel 2212 and the traveling bracket 2211 can be rotatably connected to each other via a pivot 22113. The bracket 2211 can be connected to at least one of the support member 21 and the elastic mounting member 223. The elastic member 222 can be clamped between the bracket 2211 and the elastic mounting member 223, and the elastic member 222 can be in a compressible state.

[0135] One embodiment of this application provides a bridge-crossing device 400, which, through the above-described configuration, allows the walking body 221 to roll in cooperation with the guide member 11 via its walking wheels 2212, ensuring smooth movement of the entire load-bearing component 20 relative to the guide member 10. Furthermore, the above-described configuration of the elastic member 222 ensures that when the vehicle 1 travels to the load-bearing component 20 and gravity acts on it, the elastic member 222 is compressed, causing a change in the relative position of the bracket 2211 and the elastic mounting member 223. The size of the walking member 22 protruding from the support member 21 along the second direction Z toward the side where the guide member 11 is located decreases, facilitating the switching of the bridge-crossing device 400 between the first and second states.

[0136] like Figures 7 to 9 As shown, in some optional embodiments, the bridge crossing device 400 provided in one embodiment of this application has an elastic element 222 that is telescopically arranged along the first direction Y. The support 2211 includes a first frame 22111, a second frame 22112, and a rotating shaft 22113. The first frame 22111 and the second frame 22112 are arranged crosswise. The rotating shaft 22113 is inserted into the area where the first frame 22111 and the second frame 22112 overlap. At least one of the first frame 22111 and the second frame 22112 has a degree of rotational freedom relative to the rotating shaft 22113. The first frame 22111 and the second frame 22112 are respectively rotatably connected to the side of the guide assembly 10.

[0137] 22111. The end of the second frame 22112 facing the support member 21 is movably connected to the elastic mounting member 223. The first frame 22111 and the second frame 22112 are respectively provided with elastic members 222 on the side opposite to each other in the extension direction X.

[0138] The elastic element 222 is extendable in the first direction Y, and the first frame 22111 and the second frame 22112 can be intersected and arranged in a scissor-fork structure.

[0139] The first frame 22111 and the second frame 22112 can both be plate-shaped structures, or they can be hollowed-out frame structures.

[0140] The first frame 22111 and the second frame 22112 can be stacked or staggered in the first direction Y, for example, one is partially inserted into the interior of the other and partially stacked.

[0141] The pivot 22113 is inserted into the first frame 22111 and the second frame 22112 and is rotatably connected to at least one of the first frame 22111 and the second frame 22112.

[0142] The first frame 22111 may have a first end aa and a second end bb arranged opposite to each other. The first frame 22111 and the rotating shaft 22113 are positioned between the first end aa and the second end bb. The second frame 22112 may have a third end cc and a fourth end dd arranged opposite to each other. The second frame 22112 and the rotating shaft 22113 are positioned between the third end cc and the fourth end dd. The first end aa and the third end cc are both oriented toward the support member 21. The second end bb and the fourth end dd are both rotatably connected to a traveling wheel 2212.

[0143] The elastic mounting member 223 can be rod-shaped, round, or polygonal, and can be round. The first frame 22111 and the second frame 22112 can be provided with mating holes matching the cross-sectional shape of the elastic mounting member 223 in the extension direction X, and slide in engagement with the elastic mounting member 223. The first end aa of the first frame 22111 and the third end cc of the second frame 22112 are movably connected to the elastic mounting member 223. Elastic members 222 are respectively provided on the sides of the first end aa of the first frame 22111 and the third end cc of the second frame 22112 that are opposite to each other in the extension direction X. The elastic members 222 elastically support the corresponding first end aa and third end cc. The elastic members 222 provide a force to the first end aa and the third end cc to move closer to each other.

[0144] In one embodiment of this application, a bridge crossing device 400 is provided. The support 2211 adopts the above-described structure. In the first state, the load-bearing component 20 is in a non-load-bearing state and no external force is applied. Each elastic element 222 pushes the first end aa of the corresponding first frame 22111 and the third end cc of the second frame 22112 to move closer to each other. The second end bb and the fourth end dd move closer to each other, so that the traveling member 22 protrudes from the support member 21 along the second direction Z and toward the side where the guide member 11 is located by a dimension d1. When vehicle 1 travels to the bearing assembly 20, the bearing assembly 20 is in a bearing state. Under the pressure of the vehicle 1's gravity, the elastic members 222 on both sides are compressed. The first end aa and the third end cc move away from each other, and the second end bb and the fourth end dd move away from each other. In the second direction Z, the height of the traveling member 22 in the second state is reduced compared to the first state. Correspondingly, in the second state, the traveling member 22 protrudes from the support member 21 along the second direction Z and toward the side where the guide member 11 is located by a dimension d2, which is less than d1. This allows the bridge crossing device 400 to quickly respond to the gravity of the vehicle 1 carried by the support member 21 when vehicle 1 travels onto the bearing assembly 20, so that the limiting member 40 contacts the guide member 11 to restrict the traveling member 22 from moving along the extension direction X, effectively reducing the probability of vehicle 1 skidding when passing through the bridge crossing device 400.

[0145] Continue reading Figures 7 to 9 As shown, in some optional embodiments, the bridge crossing device 400 provided in one embodiment of this application includes an elastic mounting member 223 comprising a guide rod 2231 and a stop member 2232. The guide rod 2231 extends along the extension direction X of the guide member 11. Along the extension direction X of the guide member 11, the first frame 22111 and the second frame 22112 are respectively provided with an elastic member 222 and a stop member 2232 at their opposite ends. One end of the elastic member 222 abuts against the stop member 2232 and the other end abuts against the corresponding first frame 22111 or second frame 22112.

[0146] The extension direction of the guide rod 2231 can be the same as the extension direction X of the guide member 11. Stop members 2232 are provided at both ends of the guide rod 2231 in the extension direction X.

[0147] The stop 2232 may include structural components such as nuts and snap rings that can limit the elastic element 222 in the extension direction X of the guide rod 2231.

[0148] The stop 2232 and the guide rod 2231 can be connected by a thread to ensure their relative positions are fixed. Alternatively, they can be fixed by snap-fit, interference fit, or welding.

[0149] The elastic element 222 may include structural components such as springs and rubber sleeves.

[0150] The elastic element 222 can be sleeved on the guide rod 2231 and have a clearance fit with the guide element.

[0151] The first frame 22111, the second frame 22112, and the guide rod 2231 can be connected by a clearance fit and sliding connection. The first frame 22111 and the second frame 22112 can be provided with insertion spaces, and the guide rod 2231 can be inserted into these insertion spaces and slide in a sliding fit with the first frame 22111 and the second frame 22112. Optionally, insertion holes 2234 that mate with the guide rod 2231 can be provided on the first end aa and the third end cc, respectively.

[0152] The bridge crossing device 400 provided in one embodiment of this application has an elastic mounting member 223 with the above-described structure, which can ensure the connection relationship between the bridge crossing device 400 and the first frame 22111 and the second frame 22112, and facilitate the switching of the bridge crossing device 400 between the first state and the second state.

[0153] like Figures 7 to 10 As shown, in some optional embodiments, the bridge crossing device 400 provided in one embodiment of this application has a rotating shaft 22113 extending along the first direction Y and protruding from the first frame 22111 and the second frame 22112. The rotating shaft 22113 is detachably connected to the support member 21, the first frame 22111, and the second frame 22112.

[0154] The pivot 22113 can be configured to protrude from both sides of the first frame 22111 and the second frame 22112 in the first direction Y. The first direction Y, the second direction Z, and the extension direction X of the guide 11 can be perpendicular to each other.

[0155] The pivot 22113 and the support 21 can be detachably connected along the first direction Y.

[0156] The rotating shaft 22113 can be inserted into the support member 21 along the first direction Y. The rotating shaft 22113 and the support member 21 can be detachably connected by means of threaded connection, nut locking or other methods.

[0157] One embodiment of this application provides a bridge crossing device 400. With the above-described configuration, when the traveling component 22 needs to be disassembled, the rotating shaft 22113 can be disassembled from the support component 21, and the first frame 22111 and the second frame 22112 can be disassembled and separated by pulling or other methods. This allows the entire assembly of the first frame 22111 and the second frame 22112, along with the connected traveling wheels 2212, to be separated from the support component 21, facilitating the lateral movement of the traveling component 22 and its removal from under the support component 21 for maintenance and replacement.

[0158] It is understandable that the above-described structural form of the walking component 22 is only one optional implementation method.

[0159] like Figures 11 to 13 As shown, in some embodiments, the elastic mounting member 223 can be fixedly disposed on the support member 21, the walking body 221 is connected to the elastic mounting member 223, the walking body 221 protrudes from the elastic mounting member 223 in the second direction Z toward the side where the guide component 10 is located, and the elastic member 222 is compressible in the second direction Z to adjust the size of the walking body 221 protruding from the elastic mounting member 223 in the second direction Z.

[0160] The elastic mounting member 223 can be fixed in relative position to the support member 21, and the elastic mounting member 223 can move with the movement of the support member 21. The elastic mounting member 223 and the support member 21 can be fixed by welding or locked by fasteners or other means.

[0161] The walking body 221 may have at least a partial degree of rotational freedom relative to the elastic mounting member 223.

[0162] The walking body 221 protrudes an elastic mounting member 223 along the second direction Z toward the side where the guide component 10 is located, so as to contact and cooperate with the guide component 10.

[0163] One end of the elastic element 222 can abut against the elastic mounting element 223 and the other end can abut against the walking body 221.

[0164] The elastic element 222 is compressible in the second direction Z, which can be understood as the elastic element 222 being compressible and shortened in length when subjected to an external force in the second direction Z.

[0165] One embodiment of this application provides a bridge-crossing device 400. Through the above-described configuration, when the supporting member 21 is subjected to an external force, such as when a vehicle 1 passes and presses against it, the weight of the vehicle 1 can be transmitted to the elastic member 222 through the elastic mounting member 223, causing the elastic member 222 to be compressed. The traveling body 221 moves relative to the elastic mounting member 223 towards the side where the supporting member 21 is located along the second direction Z. This reduces the size of the traveling body 221 protruding from the elastic mounting member 223 along the second direction Z, i.e., adjusts the size of the traveling body 221 protruding from the elastic mounting member 223 in the second direction Z. This allows the bridge-crossing device 400 to switch from a first state to a second state, where the limiting member 40 contacts the guide member 11, restricting the movement of the traveling member 22 along the extension direction X. When vehicle 1 passes and the external force is released, the elastic element 222 recovers its deformation and becomes longer, pushing the walking body 221 to move relative to the elastic mounting element 223 in the second direction Z, away from the side where the support element 21 is located. The bridge crossing device 400 switches from the second state to the first state. The limiting element 40 and the guide element 11 are separated. The walking element 22 has a degree of freedom of movement along the extension direction X of the guide element 11, which can also meet the functional requirements of the bridge crossing device 400.

[0166] Continue reading Figures 11 to 13 As shown, in some embodiments, the bridge crossing device 400 provided in one embodiment of this application has an elastic mounting member 223 provided with a clearance space 2233 and a plug hole 2234, a walking body 221 disposed in the clearance space 2233, the two ends of the walking body 221 in the first direction Y are respectively plugged into the plug hole 2234 and supported by the elastic mounting member 223, and each end of the walking body 221 in the first direction Y is provided with an elastic member 222.

[0167] The clearance space 2233 may include a U-shaped groove or a through groove. The clearance space 2233 can divide the elastic mounting member 223 into two parts distributed along the first direction Y. Each part is provided with a plug hole 2234.

[0168] Optionally, the insertion hole 2234 may be provided through the elastic mounting member 223 along the first direction Y. The insertion hole 2234 may be provided in communication with the clearance space 2233.

[0169] The clearance space 2233 can be used to accommodate the walking body 221, with the two ends of the walking body 221 being inserted into the insertion holes 2234 of the elastic mounting member 223 in the first direction Y.

[0170] Optionally, when the walking body 221 includes a bracket 2211 and a walking wheel 2212, with the walking wheel 2212 rotatably connected to the bracket 2211, the bracket 2211 is disposed on the elastic mounting member 223, and optionally the bracket 2211 is inserted into the insertion hole 2234 of the elastic mounting member 223. The walking wheel 2212 can be located in the clearance space 2233 and rotatably connected to the bracket 2211. The bracket 2211 may include a structure with a rotating shaft 22113. The elastic member 222 is disposed in the insertion hole 2234 and connected to the bracket 2211 and the elastic mounting member 223.

[0171] One embodiment of this application provides a bridge-crossing device 400. Through the aforementioned configuration, the clearance space 2233 can accommodate the walking body 221, allowing both ends of the walking body 221 in the first direction Y to be inserted into the insertion holes 2234 of the elastic mounting member 223, ensuring the reliability of the elastic mounting member 223's support for the walking body 221. By providing elastic members 222 at each end of the walking body 221 in the first direction Y, the stability of the bridge-crossing device 400 during switching between the first and second states is ensured.

[0172] Continue reading Figures 11 to 13 As shown, in some optional embodiments, the bridge crossing device 400 provided in one embodiment of this application further includes a travel member 224 in the traveling member 22. The travel member 224 is inserted into the elastic mounting member 223 along the second direction Z. The travel member 224 extends into the insertion hole 2234 and abuts against the traveling body 221. The size of the travel member 224 inserted into the insertion hole 2234 in the second direction Z is adjustable.

[0173] The stroke adjustment component 224 includes structures such as bolts and pins.

[0174] The stroke adjustment component 224 can be connected and fixed to the elastic mounting component 223 by means of threaded connection, snap-fit ​​connection, etc.

[0175] The bridge crossing device 400 provided in one embodiment of this application, through the above-described configuration, can adjust the initial compression amount of the elastic member 222 by adjusting the depth of the stroke adjustment member 224 inserted into the insertion hole 2234 along the second direction Z, so as to meet the load-bearing requirements of the bridge crossing device 400 for different battery swapping vehicles 1.

[0176] like Figures 14 to 17 As shown, in some optional embodiments, the support member 21 includes a plurality of support plates 211, which are distributed along the arrangement direction of the guide member 11, and each support plate 211 is connected to a walking member 22.

[0177] The number of support plates 211 can be two, three or more.

[0178] Adjacent support plates 211 can be connected to each other. Alternatively, adjacent support plates 211 can be set independently and connected to the drive assembly 30 respectively.

[0179] The number of traveling parts 22 provided on each support plate 211 can be multiple, such as four or more.

[0180] The bridge-crossing device 400 provided in one embodiment of this application, through the above-described configuration, can reduce the molding difficulty of the support member 21 and ensure the flatness of its surface used to support the vehicle 1. This avoids warping deformation caused by excessive area during processing, preventing excessive local pressure on the vehicle 1 when it is pressed down, and improves the reliability of the bridge-crossing device 400.

[0181] In some alternative embodiments, at least two of the plurality of support plates 211 have a difference in hardness.

[0182] The thickness of at least two support plates 211 can differ, thereby resulting in differences in their hardness. Of course, the materials of at least two support plates 211 can also differ; for example, the hardness of the material of one support plate 211 can be greater than the hardness of the material of the other support plate 211.

[0183] For example, taking the support member 21 as having three support plates 211, each support plate 211 can be provided with four walking members 22, so that the hardness of the support plate 211 located in the middle is less than that of the support plates 211 located on both sides.

[0184] The bridge crossing device 400 provided in one embodiment of this application, through the above-described configuration, can make the hardness of the support plate 211 with a large bearing pressure greater than that of the support plate 211 with a small bearing pressure. For example, the hardness of the support plate 211 in contact with the vehicle 1 can be set to be greater, thereby ensuring the bearing capacity of the bridge crossing device 400 and reducing costs.

[0185] In some alternative embodiments, a connector 212 connects the multiple support plates 211. The connector 212 may include a connecting rod, a connecting plate, or other structures. This allows the multiple support plates 211 to be connected as a whole, facilitating synchronous driving.

[0186] Continue reading Figures 14 to 17 As shown, in some optional embodiments, the drive assembly 30 includes a drive member 31, a transmission wheel 32, and a traction member 33. The traction member 33 is wound around the transmission wheel 32. The drive member 31 is connected to the transmission wheel 32 and drives the transmission wheel 32 to rotate. The bearing assembly is connected to the traction member 33. The traction member 33 includes one of a transmission belt and a transmission chain.

[0187] The driving component 31 may include a driving motor, a driving motor 300, or other functional components that can drive the transmission wheel 32 to rotate.

[0188] The drive wheel 32 may include a pulley or a sprocket.

[0189] Transmission belts include toothed belts, V-belts, etc.

[0190] With the above configuration, the drive member 31 can drive the transmission wheel 32 to rotate, and the transmission wheel 32 can drive the traction member 33 to move along the extension direction X of the guide member 11. This, in turn, drives the support member 21 to move along the extension direction X. The reciprocating movement of the bearing assembly 20 in the extension direction X can be achieved by driving the drive member 31 in either the forward or reverse direction.

[0191] like Figures 14 to 17 As shown, in some alternative embodiments, the drive assembly 30 further includes a buffer 34 connected to the traction member 33, and the buffer 34 is at least partially telescopic in the extension direction X of the guide 11.

[0192] The buffer 34 may include a buffer spring, a rubber pad, or an air bladder.

[0193] The buffer 34 can abut against the bearing assembly 20 in the extending direction X of the guide 11.

[0194] One embodiment of this application provides a bridge crossing device 400, which, by providing a buffer 34, can effectively prevent the impact load on the traction component 33 from damaging the drive assembly 30 when the battery swapping vehicle 1 passes through.

[0195] In some alternative embodiments, the support member 21 is provided with buffer members 34 at both ends of the extension direction X of the guide member 11.

[0196] The buffers 34 at both ends of the support member 21 in the extension direction X can abut against the support member 21.

[0197] With the above configuration, the buffer component 34 provides a buffering effect when the load-bearing component 20 moves forward and backward in the extension direction X of the guide component 11, which helps to ensure the buffering requirement of the impact load on the chain when the battery swapping vehicle 1 passes.

[0198] It is understood that the above-described structure of the drive component 30 is only an optional implementation method. In some embodiments, it may also include a telescopic cylinder, a power source drive gear rack, or other drive structure forms to achieve linear drive.

[0199] like Figure 3 , Figure 18As shown, in some optional embodiments, the bridge device 400 further includes a support base 50, and the guide assembly 10 is provided with support bases 50 on both sides of the first direction Y, and the guide member 11 located at the edge of the first direction Y is connected to the support base 50.

[0200] The support base 50 may include a support plate or a support frame or other structures.

[0201] With the above configuration, the battery swapping vehicle 1 can be supported by the support base 50, and the support base 50 can provide support and protection for the installation of the guide 11.

[0202] In some alternative embodiments, the support base 50 is provided with a recess 51 recessed along the first direction Y, and a guide 11 located at the edge in the first direction Y partially extends into the recess 51.

[0203] The shape of the recess 51 can match the shape of the guide 11.

[0204] The above setup facilitates the positioning and installation of the guide 11 via the support base 50, ensuring the support requirements for the guide 11 are met.

[0205] Continue reading Figure 17 , Figure 18 As shown, in some alternative embodiments, the support assembly 20 further includes a guide wheel assembly 60, which is connected to the support member 21 and abuts against one side surface of the guide member 11 in the first direction Y.

[0206] Optionally, each support plate may be provided with multiple sets of guide wheel assemblies 60. The guide wheel assembly 60 may be in contact with a guide member 11 for guidance, or each guide member 11 may be provided with a guide wheel assembly 60224.

[0207] With the above configuration, the guide wheel assembly 60 can provide limiting for the load-bearing assembly 20 and the guide member 11 in the first direction Y. Furthermore, it can ensure the smooth movement of the load-bearing assembly relative to the guide assembly 10.

[0208] like Figures 3 to 10 , Figures 14 to 18As shown, an embodiment of this application provides a bridge crossing device 400, including a guide assembly 10, a load-bearing assembly 20, a drive assembly 30, a limiting member 40, and a support base.

The elastic element 222 is compressible. The bracket 2211 includes a first frame 22111, a second frame 22112, and a rotating shaft 22113. The first frame 22111 and the second frame 22112 are arranged crosswise. The rotating shaft 22113 is inserted into the area where the first frame 22111 and the second frame 22112 overlap. At least one of the first frame 22111 and the second frame 22112 has a degree of rotational freedom relative to the rotating shaft 22113. The first frame 22111 and the second frame 22112 are rotatably connected to the side facing the guide assembly 10, respectively, and the end of the first frame 22111 and the second frame 22112 facing the support member 21 is movably connected to the elastic mounting member 223. The first frame 22111 and the second frame 22112 are respectively provided with elastic elements 222 on the side facing away from each other in the extension direction X. The elastic mounting member 223 includes a guide rod 2231 and a stop member 2232. The guide rod 2231 extends along the extension direction X of the guide member 11. Along the extension direction X of the guide member 11, the first frame 22111 and the second frame 22112 are respectively provided with the stop member 2232 at their opposite ends. One end of the elastic member 222 abuts against the stop member 2232 and the other end abuts against the corresponding first frame 22111 or second frame 22112. The rotating shaft 22113 extends along the first direction Y and protrudes from the first frame 22111 and the second frame 22112. The rotating shaft 22113 is detachably connected to the support member 21, the first frame 22111, and the second frame 22112. The support member 21 includes three support plates 211, which are distributed along the arrangement direction of the guide member 11. Each support plate 211 is connected to four sets of traveling members 22 and four sets of guide wheel assemblies 60. The hardness of the support plate 211 in the middle is less than that of the support plates 211 on both sides.

[0209] A drive assembly 30 is connected to a support assembly 20 and is used to drive the support assembly 20 to move along the extension direction X of the guide 11. The drive assembly 30 includes a drive member 31, a transmission wheel 32, a traction member 33, and a buffer member 34. The traction member 33 is wound around the transmission wheel 32. The drive member 31 is connected to the transmission wheel 32 and drives the transmission wheel 32 to rotate. The support assembly is connected to the traction member 33, and the traction member 33 includes a transmission chain. The buffer member 34 is connected to the traction member 33 and is at least partially telescopic in the extension direction X of the guide 11.

For example, four limiting members 40 can be disposed on each support plate 211, with each pair of limiting members 40 corresponding to one of the guide members 11.

In the first state, the limiting member 40 is separated from the guide member 11, and the traveling member 22 has a degree of freedom of movement along the extension direction X of the guide member 11. In response to the gravity of the vehicle, the bridge crossing device 400 can switch from the first state to the second state. In the second state, the limiting member 40 is in contact with the guide member 11, and the limiting member 40 restricts the movement of the traveling member 22 along the extension direction X. The first direction Y, the second direction Z, and the extension direction X are perpendicular to each other.

In the first state, the limiting member 40 is separated from the guide member 11, and the traveling member 22 can move along the extension direction X of the guide member 11 to ensure the battery swapping needs of the vehicle 1. When the vehicle 1 passes through the bridge crossing device 400 before and after battery swapping, the bridge crossing device 400 can be in the second state, so that the limiting member 40 is in contact with the guide member 11. The limiting member 40 restricts the traveling member 22 from moving along the extension direction X, and the first direction Y, the second direction Z, and the extension direction X are perpendicular to each other.
