Description

Technical Field

[0001] This application relates to the field of fast battery swapping technology, and more particularly to a vehicle and protective assembly. Background Technology

[0002] The application of new energy batteries in daily life and industry is becoming increasingly widespread. For example, new energy vehicles equipped with batteries are already widely used, and batteries are also increasingly being applied in energy storage. In new energy vehicles equipped with batteries, the batteries can provide all or part of the power.

[0003] Currently, some vehicles need to have their battery swapped to quickly replenish their power when the battery is depleted. Therefore, improving the stability and efficiency of the battery swapping process is a problem that needs to be solved by those in this field. Summary of the Invention

[0004] This application provides a vehicle and a protective assembly that improves the stability and efficiency of the battery swapping process.

[0005] The technical solution of this application embodiment is implemented as follows: This application provides a vehicle including a chassis and a body. The vehicle further includes: a battery mounting bracket connected to the chassis; a battery device detachably mounted to the battery mounting bracket; and a protective assembly including an inner protective component and an outer protective component both connected to the battery mounting bracket. The inner protective component forms a protective cavity with a downward-facing first opening. At least a portion of the battery device extends into the protective cavity through the first opening. The outer protective component covers the side of the inner protective component facing away from the protective cavity.

[0006] The vehicle provided in this application firstly features a battery mounting bracket connected to the chassis, on which the battery pack is detachably mounted for easy maintenance and replacement. Secondly, a protective assembly is incorporated to protect the battery pack, reducing the accumulation of foreign objects and the frequency of cleaning, thereby lowering cleaning costs and improving battery swapping efficiency. Furthermore, the protective assembly includes an inner protective component and an outer protective component. The inner protective component has a protective cavity to accommodate a portion of the battery pack, reducing the direct accumulation of foreign objects on its upper surface. Simultaneously, the outer protective component covers the outer side of the inner protective component, further blocking impacts from the external environment and foreign object intrusion. Because the outer protective component is located on the outermost layer, it acts as the first line of defense, absorbing most of the external impact force and blocking large foreign objects, thus reducing the risk of damage to the inner protective component and the battery pack. This helps reduce the accumulation of foreign objects on the battery pack, improves the alignment accuracy between the battery pack and the battery mounting bracket, and enhances the stability of the battery swapping process. In addition, in some battery swapping scenarios, vehicles and battery devices can be cleaned outside the station. Specific cleaning methods include, but are not limited to, directly rinsing the vehicles and battery devices or replacing the protective assembly, which makes cleaning operations convenient and further improves battery swapping efficiency.

[0007] In some embodiments, the stiffness of the outer protective component is greater than that of the inner protective component, and the impact resistance of the outer protective component is greater than that of the inner protective component.

[0008] Thus, the outer protective component uses materials with higher rigidity and impact resistance, enhancing its resistance to external physical impacts. This can protect the inner protective component and battery device from damage to a greater extent, improving the stability of the entire protective assembly under complex working conditions. Especially in harsh environments such as coal mines, it can significantly reduce the probability of mud, carbon ash, sand, and other particulate matter depositing on the outer surface of the battery device, thereby extending the battery device's lifespan and improving battery swapping efficiency and stability.

[0009] In some embodiments, the outer protective component is made of metal, and the inner protective component is made of plastic.

[0010] This design creates a complementary protection system between the inner and outer protective components. The outer protective component is responsible for withstanding strong external impacts, while the inner protective component buffers minor internal vibrations or collisions and reduces the deposition of foreign matter on the outer surface of the battery pack. This dual-layer structure not only improves the overall protection level but also addresses weight reduction requirements, helping to decrease vehicle weight and improve range.

[0011] In some embodiments, at least a portion of the outer protective component fully covers the inner protective component from above.

[0012] In this way, by having the outer protective component completely cover the inner protective component from above, the outer protective component shields and protects both the inner protective component and the upper surface of the battery device. This prevents foreign objects from accumulating on the upper surface of the battery device, improves the alignment accuracy of the battery device and the battery mounting bracket, enhances the stability of the battery swapping process, and increases the battery swapping efficiency.

[0013] In some embodiments, the top of the inner protective component has a first clearance opening and a second clearance opening, and the top of the battery device has a battery terminal electrical connector and a battery terminal water connector, which are exposed through the first clearance opening and the second clearance opening, respectively.

[0014] Thus, the battery-side electrical connector and battery-side water connector at the top of the battery unit are exposed through the first and second avoidance openings, respectively, for connection to the vehicle-side electrical connector and vehicle-side water connector. The outer protective component fully covers the inner protective component from above. That is, the outer protective component covers and shields the first and second avoidance openings, as well as the battery-side electrical connector and battery-side water connector from above, reducing the accumulation of foreign objects in these locations. This helps improve battery swapping stability, reduces the number of cleaning cycles, and thus improves battery swapping efficiency. In addition, since the battery-side electrical connector and battery-side water connector of the battery unit are shielded and protected by the outer protective component, other parts of the battery unit can be directly rinsed with liquid, simplifying the cleaning operation and improving battery swapping efficiency.

[0015] In some embodiments, the portion of the battery device located within the protective cavity has its outer surfaces, except for the outer surface where the battery terminal electrical connector and the battery terminal water connector are located, covered by an inner protective component.

[0016] This ensures that the outer surface of the battery device is covered by the inner protective components as much as possible, maximizing the protection of the battery device, reducing the accumulation of foreign objects on the outer surface of the battery device, improving battery swapping stability, and reducing the number of cleaning cycles.

[0017] In some embodiments, the battery device has an upwardly protruding first protrusion and a second protrusion. The first protrusion has a second protrusion on each side along the width direction of the vehicle. The first protrusion and the second protrusion are spaced apart. The inner protective assembly includes a plurality of protective covers, including a first protective cover and a second protective cover. The first protective cover has a second protective cover on each side along the width direction of the vehicle. The first protective cover has a first clearance opening and a second clearance opening. The first protrusion is located in the protective cavity of the first protective cover, and all outer surfaces of the first protrusion except for the outer surface where the battery terminal electrical connector and the battery terminal water connector are located are covered by the first protective cover. The second protrusion is located in the protective cavity of the second protective cover, and the outer surface of the second protrusion is completely covered by the second protective cover.

[0018] Thus, a battery-side electrical connector and a battery-side water connector are located at the first protrusion in the middle of the vehicle width direction. A first protective cover has a first avoidance opening and a second avoidance opening at the corresponding locations of these connectors. All other outer surfaces of the first protrusion are covered, and the second protective cover fully covers the outer surface of the second protrusion. This ensures that the outer surface of the battery device is covered as much as possible by the inner protective components, maximizing the protection of the battery device, reducing the accumulation of foreign objects on the outer surface of the battery device, improving battery swapping stability, and reducing the frequency of cleaning. Furthermore, positioning the first protrusion with the battery-side electrical connector and battery-side water connector between the second protrusion ensures that both sides of the first protrusion along the vehicle width direction are shielded by the second protrusion and the second protective cover. This prevents liquid from entering the battery-side electrical connector and battery-side water connector during the rinsing of the battery device and protective assembly from the left, right, and top sides, improving the safety and reliability of rinsing the battery device.

[0019] In some embodiments, the battery mounting bracket includes a plurality of mounting beams extending along the width direction of the vehicle and connected to the longitudinal beams of the chassis. The bottom edge of the mounting beams forms a mounting flange, and the mounting flange forms a plurality of mounting through holes extending along the vertical direction of the vehicle. The battery assembly includes a locking assembly passing through the mounting through holes and detachably connected to the mounting flange. The inner protective assembly includes a protective cover forming a protective cavity. The protective cover has a connecting flange folded away from the protective cavity at the edge of a first opening, and the connecting flange is connected to the mounting flange.

[0020] Thus, by setting multiple mounting beams extending along the vehicle width and connecting them to the chassis longitudinal beams, the structural strength and stability of the battery mounting bracket are improved. The connecting flanges at the bottom of the mounting beams form multiple mounting through holes, providing reliable fixing points for the battery unit's locking components and improving the battery unit's installation stability. Simultaneously, the connecting flanges at the edge of the protective cover connect with the mounting flanges, achieving a connection between the protective cover and the battery mounting bracket. That is, the mounting flanges also serve as fixing points for both the battery unit and the protective cover. This not only simplifies the structure of the mounting beams but also allows the protective cover to cover the interface between the battery unit and the mounting flanges, reducing gaps and effectively minimizing the accumulation of foreign matter on the battery unit, thereby further enhancing the protective effect.

[0021] In some embodiments, the connecting flange is connected to the upper or lower surface of the mounting flange, a locking assembly is provided through a portion of the mounting through hole, and the connecting flange covers the remaining portion of the mounting through hole.

[0022] In this way, by covering unused mounting holes with the connecting flange, the probability of foreign matter depositing into the battery device through these mounting holes is reduced, improving the protection effect and thus enhancing the stability of battery swapping. Moreover, the larger area of ​​the connecting flange facing the mounting flange helps to improve the strength of the connecting flange and the connection strength between the connecting flange and the mounting flange.

[0023] In some embodiments, the protective assembly further includes a protective housing connected to the upper surface of the mounting flange, covering a mounting through-hole through which a locking component is disposed, wherein a portion of the locking component extending from above the mounting through-hole is accommodated within the protective housing.

[0024] Thus, the protective housing further enhances the protection of the locking components, mounting holes, and surrounding area, reducing the intrusion of foreign objects and preventing blockage of the mounting holes. Containing the locking components within the protective housing not only reduces the probability of dust accumulation on the components but also decreases the likelihood of impacts from external objects, improving the reliability of the locking mechanism and the stability of battery swapping.

[0025] In some embodiments, the battery mounting bracket further includes a first gasket connected to the upper side of the mounting flange and disposed around a mounting through hole through which a locking assembly is provided. The locking assembly abuts against the upper surface of the first gasket, and the protective shell abuts against the upper surface of the first gasket.

[0026] Thus, the first gasket reduces wear on the mounting flange caused by repeated unlocking and unlocking operations of the locking components, which helps extend its lifespan. Furthermore, the first gasket is placed between the mounting flange and the protective shell, which helps improve the reliability of the protective shell installation, reduces loosening or damage caused by vibration or external impact, improves the stability of the overall structure, and thus improves the protective effect of the protective shell, further enhancing the stability of battery swapping.

[0027] In some embodiments, the protective cover has mounting beams on its front and rear sides along the longitudinal direction of the vehicle, and the battery mounting bracket also includes side beams that extend in the longitudinal direction and connect with the mounting beams provided on the front and rear sides of the protective cover. The side beams block one side of the protective cover along the width of the vehicle.

[0028] By installing mounting beams on the front and rear sides of the protective cover, the battery pack is not only securely connected to the battery mounting bracket, but the connection between the protective cover and the battery mounting bracket is also strengthened. This reduces the possibility of protective failure due to long-term use or external impact, thereby reducing the chance of battery swapping failure due to foreign object accumulation, and significantly improving battery swapping efficiency and stability. Furthermore, the side beams enhance the overall structural strength of the battery mounting bracket, especially its support capacity in the front-rear direction. Simultaneously, the side beams, positioned on one side of the protective cover, reduce the impact of foreign objects from the left and right sides of the vehicle onto the protective cover, ensuring adequate protection for the battery pack under various operating conditions.

[0029] In some embodiments, the outer protective assembly includes a plurality of protective outer plates connected to the mounting beam and side beam, and covering the protective cover, the mounting beam and side beam on the side facing away from the protective cavity.

[0030] By installing multiple protective outer panels connected to the mounting beam and side beams, and covering the protective cover, mounting beam, and side beams on the side facing away from the protective cavity, the entry of foreign objects from the external environment into the battery device area can be reduced. This improves the cleanliness of the battery device, enhances battery swapping efficiency and stability, and extends the battery device's lifespan. Furthermore, the multiple protective outer panels expand the coverage of the outer protective components, allowing them to more comprehensively enclose the protective cover, mounting beam, and side beams, forming a continuous protective barrier. This not only improves overall protective performance but also enhances the cleanliness and aesthetics of the appearance.

[0031] In some embodiments, the protective assembly further includes a fixed frame, which includes a plurality of first beams extending in the vehicle width direction and a plurality of second beams extending in the front-rear direction. Each of the plurality of mounting beams is connected to the top of a first beam, and both ends of the second beams overlap the top of the mounting beams and are connected to the first beams. At least a portion of the protective outer panel is connected to the first beams and the second beams.

[0032] In this way, the fixed frame provides more mounting points for the protective outer panel, improving its stability. At the same time, the fixed frame also enhances the structural rigidity of the battery mounting bracket, helping to disperse and absorb external impact forces, thereby better protecting the battery device from damage.

[0033] In some embodiments, the plurality of mounting beams includes at least two first mounting beams and at least four second mounting beams. The first mounting beams are connected between two longitudinal beams of the chassis. The at least two first mounting beams are spaced apart along the longitudinal direction. Each longitudinal beam is connected to at least two second mounting beams on the side facing away from the other longitudinal beam along the vehicle width direction. The at least two second mounting beams connected to the same longitudinal beam are spaced apart along the longitudinal direction. The inner protective assembly includes a plurality of protective covers. The plurality of protective covers includes at least one first protective cover and at least two second protective covers. The first protective covers are connected between adjacent first mounting beams along the longitudinal direction, and the second protective covers are connected between adjacent second mounting beams along the longitudinal direction. The battery device forms an upwardly protruding first protrusion and a second protrusion. The first protrusion has a second protrusion on each side along the vehicle width direction. The first protrusion and the second protrusion are spaced apart. The first protrusion extends into the first protective cover, and the second protrusion extends into the second protective cover.

[0034] In this way, by setting multiple mounting beams and multiple protective covers, zoned protection of different parts of the battery device is achieved, which allows each protrusion to fit the inner wall of the protective cavity of its corresponding protective cover, thus achieving a better protective effect.

[0035] In some embodiments, the battery mounting bracket further includes a connector mounting plate and a vehicle-end electrical connector and a vehicle-end water connector mounted on the connector mounting plate. The connector mounting plate is connected between adjacent first mounting beams. A first protective cover is located on the underside of the connector mounting plate and is connected to the connector mounting plate. The first protective cover has a first clearance opening and a second clearance opening. A first protrusion is provided with a battery-end electrical connector and a battery-end water connector. The battery-end electrical connector is connected to the vehicle-end electrical connector through the first clearance opening, and the battery-end water connector is connected to the vehicle-end water connector through the second clearance opening.

[0036] Thus, the connector mounting plate provides a stable mounting platform for the vehicle-side electrical connector and the vehicle-side water connector, enabling reliable connection between them and the battery device. The vehicle-side electrical connector on the connector mounting plate connects to the battery-side electrical connector of the battery device via a first bypass opening, achieving electrical connection. The vehicle-side water connector on the connector mounting plate connects to the battery-side water connector of the battery device via a second bypass opening, achieving water connection. Furthermore, since many wires and water pipes need to be arranged above the connector mounting plate, a first protective cover is installed below the connector mounting plate. This reduces the impact on the wires and water pipes, minimizes the number of openings in the first protective cover, and allows the first protective cover to cover the first protrusion as much as possible, further improving the protective effect and enhancing the stability of battery swapping.

[0037] In some embodiments, the first mounting beam has a through hole extending in the front-rear direction.

[0038] Thus, the placement of the wiring through-holes facilitates the laying of wire harnesses and conduits, reducing the risk of malfunctions caused by wire tangling or jamming. Simultaneously, the through-hole design aids in heat dissipation and ventilation, reducing the impact of localized temperature rises on the battery unit, thereby improving its operating efficiency. Furthermore, the wiring through-holes also contribute to weight reduction.

[0039] In some embodiments, the first mounting beam is connected to two longitudinal beams at both ends along the vehicle width direction, and the second mounting beam is connected to the longitudinal beam at one end along the vehicle width direction and to the side beam at the other end.

[0040] In this way, through a reasonable connection method, a stable square frame structure is formed between the mounting beam and the longitudinal beams and side beams of the chassis, which improves the overall rigidity and deformation resistance of the battery mounting frame. This not only enhances the load-bearing capacity of the battery mounting frame but also optimizes the stress distribution, which helps to extend its service life. In addition, this structure is more suitable for installing square battery devices.

[0041] In some embodiments, the protective assembly further includes a gap-blocking assembly disposed at the bottom edge of the side beam, which covers a portion of the gap between the second protective cover and the battery device.

[0042] In this way, the gap-blocking assembly covers the gap between the protective cover and the battery device on both sides along the vehicle width direction, reducing the intrusion of foreign objects from the gap. Since foreign objects are more likely to approach the left and right sides of the battery device, setting the gap-blocking assembly here can reduce the probability of foreign objects approaching the battery device, improve the cleanliness of the battery device, and improve the stability of battery swapping.

[0043] In some embodiments, the battery device has an upward-facing edge surface surrounding the outer periphery of the first protrusion and the second protrusion, and the gap assembly abuts against the edge surface.

[0044] In this way, the tight fit between the gap-sealing assembly and the edge of the battery device enhances the protective effect, reduces the chance of foreign objects intruding from the edge, thereby improving the smoothness of the battery swapping process and reducing the problem of locking failure caused by the accumulation of foreign objects.

[0045] In some embodiments, the gap-blocking assembly includes a brush connected to the lower edge of the side beam and abutting against the edge surface.

[0046] Thus, the brush, utilizing its elastic properties, forms a tight contact with the edge surface, providing a physical barrier that effectively reduces the intrusion of foreign objects from the sides. This is especially beneficial during car washes, where high-pressure water jets may cause water mist penetration or the accumulation of fine particles. The embodiments of this application can improve battery swapping efficiency and stability, and extend the service life of the battery device and related structures. Furthermore, the brush also acts as a buffer, reducing the impact on the battery device when the vehicle travels on bumpy roads, further enhancing overall protection performance.

[0047] In some embodiments, the gap-blocking assembly includes a resilient shielding strip connected to the lower edge of the second protective cover on the side away from the first protective cover, and the resilient shielding strip abutting against the edge surface.

[0048] Thus, the flexible shielding strip provides the gap-blocking assembly with a certain buffering capacity and adaptability, and can automatically adjust its fit to the edge surface, thereby maintaining a good protective effect in different working scenarios, and further improving the cleanliness, battery swapping efficiency and battery swapping stability of the battery device.

[0049] In some embodiments, the outer protective assembly includes a plurality of protective outer plates, including a first protective outer plate, a second protective outer plate, and a third protective outer plate. The first protective outer plate is disposed above the first mounting beam and covers the first protective cover. The second protective outer plate is disposed above the second mounting beam and covers the second protective cover. The front side, rear side, and side facing away from the longitudinal beam along the vehicle width direction of the second protective cover are all covered by the third protective outer plate. The third protective outer plate is located on the side of the second mounting beam facing away from the second protective cover.

[0050] In this way, by setting multiple protective outer plates to construct an outer protective assembly, a large area of ​​coverage is formed for the battery device, protective cover and its surrounding area; and by rationally arranging the positions of the first, second and third protective outer plates, the outer protective assembly can effectively protect the battery device from different directions, improve the cleanliness of the mating parts between the battery device and the battery mounting bracket, and improve the stability of battery swapping.

[0051] In some embodiments, the two ends of the first protective outer panel along the vehicle width direction respectively overlap and connect the upper surfaces of the two second protective outer panels.

[0052] The left and right edges of the first protective outer panel extend to the top of the two second protective outer panels and connect with them. The overlapping arrangement between the first and second protective outer panels makes the entire roof structure a continuous whole in the vehicle width direction, thereby improving the overall sealing and stability of the structure. The overlapping method between the first and second protective outer panels not only enhances the structural strength of the outer protective components, but also helps to reduce the intrusion of foreign objects from the gaps between the protective outer panels.

[0053] A second aspect of this application provides a protective assembly for protecting a battery device mounted on a battery mounting bracket in a vehicle. The protective assembly includes an inner protective component and an outer protective component, both connected to the battery mounting bracket. The inner protective component forms a protective cavity with a downward-facing first opening. At least a portion of the battery device extends into the protective cavity through the first opening. The outer protective component covers the side of the inner protective component that faces away from the protective cavity.

[0054] The protective assembly comprises an inner protective component and an outer protective component. The inner protective component has a protective cavity to accommodate a portion of the battery device, reducing the direct accumulation of foreign objects on the upper surface of the battery device. Simultaneously, the outer protective component covers the outer side of the inner protective component, further blocking impacts and foreign object intrusion from the external environment. Because the outer protective component is located on the outer layer, it acts as the first line of defense, absorbing most of the external impact force and blocking large foreign objects, thereby reducing the risk of damage to the inner protective component and the battery device. This also helps reduce the accumulation of foreign objects in the battery device, improves the alignment accuracy of the battery device and the battery mounting bracket, and enhances the stability of the battery swapping process. Furthermore, the protective assembly reduces the frequency of cleaning the battery device, thereby reducing cleaning costs and improving battery swapping efficiency. In some battery swapping scenarios, the vehicle and battery device can be cleaned off-site. Specific cleaning methods include, but are not limited to, directly washing the vehicle and battery device or replacing the protective assembly, making cleaning operations convenient and further improving battery swapping efficiency.

[0065] The following is a detailed description of this application.

[0066] The application of new energy batteries in daily life and industry is becoming increasingly widespread. New energy batteries are not only used in energy storage systems for hydropower, thermal power, wind power, and solar power plants, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, and electric trucks, as well as in aerospace and other fields. With the continuous expansion of the application areas of power batteries, the market demand is also constantly increasing.

[0067] With the development of electric vehicles, users have increasingly higher requirements for vehicle range and charging. Traditional charging methods via charging stations can no longer meet the needs of some electric vehicles, especially commercial vehicles such as heavy-duty trucks, where long charging times severely impact operational efficiency and utilization. Therefore, replacing battery devices at battery swapping stations can replenish the energy of electric vehicles. Compared to connecting to charging stations, battery swapping provides a faster way to replenish energy.

[0068] In related technologies, battery devices are connected to vehicles via battery mounting brackets. Depending on the vehicle model, the battery device may be partially or completely exposed to the exterior of the vehicle body, such as battery devices mounted on the underside of large commercial vehicles. On the one hand, large commercial vehicles operate under complex and harsh conditions, such as in mining areas, construction sites, and docks, where the battery device is completely and continuously exposed to the environment. This makes it easy for foreign objects such as mud, coal, stones, and tree branches to accumulate or adhere to the battery device. These foreign objects accumulate to form solid foreign object blocks that adhere to the battery device. On the other hand, the structure of the battery device and battery mounting bracket is complex, and a large amount of foreign objects can accumulate at the joints or on individual components of these structures.

[0069] When a vehicle goes to a battery swapping station, if the swap is performed directly, foreign objects accumulated on the vehicle and battery assembly may cause improper fit between the locking components and the battery mounting bracket, or interfere with the swapping environment and equipment, affecting the stability of the swap and directly or indirectly leading to swapping failure. To address this, the vehicle and battery assembly need to be cleaned before a swap. This cleaning process is time-consuming, thus impacting swapping efficiency.

[0070] Based on the above, this solution needs to consider protecting the battery device. On the one hand, it should minimize the accumulation of foreign objects on the battery device; on the other hand, it should consider the convenience of cleaning the vehicle and the battery device, thereby improving the battery swapping efficiency and the stability of the battery swapping process.

[0071] This application addresses the problems existing in the aforementioned related technologies by proposing a vehicle, which includes a chassis and a body, and further includes a battery mounting bracket, a battery device, and a protective assembly. The battery mounting bracket is connected to the chassis; the battery device is detachably mounted on the battery mounting bracket; the protective assembly includes an inner protective component and an outer protective component, both connected to the battery mounting bracket. The inner protective component forms a protective cavity with a downward-facing first opening, at least a portion of the battery device extends into the protective cavity through the first opening, and the outer protective component covers the side of the inner protective component facing away from the protective cavity.

[0072] The vehicle provided in this application firstly features a battery mounting bracket connected to the chassis, on which the battery pack is detachably mounted for easy maintenance and replacement. Secondly, a protective assembly is incorporated to protect the battery pack, reducing the accumulation of foreign objects and the frequency of cleaning, thereby lowering cleaning costs and improving battery swapping efficiency. Furthermore, the protective assembly includes an inner protective component and an outer protective component. The inner protective component has a protective cavity to accommodate a portion of the battery pack, reducing the direct accumulation of foreign objects on its upper surface. Simultaneously, the outer protective component covers the outer side of the inner protective component, further blocking impacts from the external environment and foreign object intrusion. Because the outer protective component is located on the outermost layer, it acts as the first line of defense, absorbing most of the external impact force and blocking large foreign objects, thus reducing the risk of damage to the inner protective component and the battery pack. This helps reduce the accumulation of foreign objects on the battery pack, improves the alignment accuracy between the battery pack and the battery mounting bracket, and enhances the stability of the battery swapping process. In addition, in some battery swapping scenarios, vehicles and battery devices can be cleaned outside the station. Specific cleaning methods include, but are not limited to, directly rinsing the vehicles and battery devices or replacing the protective assembly, which makes cleaning operations convenient and further improves battery swapping efficiency.

[0073] In the following embodiments, for ease of explanation, a vehicle 1000 is used as an example. The description is as follows with reference to the accompanying drawings.

[0074] Figure 1 This is a structural schematic diagram of a vehicle 1000 according to one or more embodiments.

[0075] Vehicle 1000 can be a fuel-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid vehicles, or range-extended vehicles, etc. The vehicle can be a commercial vehicle. This application embodiment does not impose any special restrictions on the aforementioned vehicles.

[0076] like Figure 1As shown, a battery device 100 is installed inside the vehicle 1000. The battery device 100 can be located at the bottom, front, or rear of the vehicle 1000. The battery device 100 can be used to power the vehicle 1000; for example, the battery device 100 can serve as the operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300. The controller 200 is used to control the battery device 100 to supply power to the motor 300, for example, to meet the power needs of the vehicle 1000 during starting, navigation, and driving.

[0077] In some embodiments of this application, the battery device 100 can not only serve as the operating power source for the vehicle 1000, but also as the driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0078] In some embodiments of this application, the vehicle 1000 includes a chassis and a body mounted on the chassis. The body forms the vehicle exterior and passenger compartment and protects the occupants located in the passenger compartment. The chassis is located below the body and carries the engine, battery unit 100, and other components.

[0079] Figure 2 This is an exploded structural diagram of a battery device 100 according to one or more embodiments.

[0080] like Figure 2 As shown in this embodiment, the battery device 100 may include one or more battery cell assemblies 20 for providing voltage and capacity. The battery cell assembly 20 may include multiple battery cells, which can be connected in series, parallel, or mixed connections via a busbar.

[0081] In some embodiments, the battery cell assembly 20 is typically formed by arranging a plurality of battery cells.

[0082] A single battery cell can be a rechargeable battery. A rechargeable battery is a battery cell that can be recharged after it has been discharged, allowing the active materials to be activated and the cell to continue to be used.

[0083] The battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and this application does not specifically limit it.

[0084] As an example, the battery cell assembly 20 can be a battery module, which is formed by arranging and fixing multiple battery cells together to form an independent module. As an example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0085] In some embodiments, the battery device 100 may be a battery pack, which may include a battery case 10 and one or more battery cell assemblies 20, the battery cell assemblies 20 being housed in the battery case 10.

[0086] As an example, the battery cell assembly 20 can be a battery module, which can be housed in the battery case 10 by fixing the battery module in the battery case 10.

[0087] As an example, the battery cell assembly 20 can also be housed in the battery box 10 by directly fixing multiple battery cells to the battery box 10.

[0088] As an example, the battery box 10 may include a box body 102 and a box cover 101. The box body 102 and the box cover 101 are fastened together to form a closed space inside the battery box 10 to house the battery cell assembly 20. Here, "closed" means covered or closed, and can be sealed or unsealed.

[0089] Below, refer to Figures 3 to 19 Some embodiments of this application will be described in detail.

[0091] In some embodiments of this application, for ease of explanation, the vehicle's front-to-back direction, vertical direction, and width direction are defined, such as... Figures 3 to 9 and Figures 14 to 19 As shown, the direction of arrow ab is the "front-to-back direction of the vehicle", the direction of arrow cd is the "width direction of the vehicle", and the direction of arrow ef is the "vertical direction of the vehicle". Among them, the direction pointed to by arrow a is the front side of the vehicle, the direction pointed to by arrow b is the rear side of the vehicle, the direction pointed to by arrow c is the right side of the vehicle, the direction pointed to by arrow d is the left side of the vehicle, the direction pointed to by arrow e is the top of the vehicle, and the direction pointed to by arrow f is the bottom of the vehicle.

[0092] Embodiments of this application provide a vehicle, such as Figures 3 to 5 As shown, the vehicle 1000 includes a chassis 400 and a body (not shown in the figure). The vehicle 1000 also includes a battery mounting bracket 500, a battery device 100, and a protective assembly 600. The battery mounting bracket 500 is connected to the chassis 400. The battery device 100 is detachably mounted to the battery mounting bracket 500. The protective assembly 600 includes an inner protective component 1 and an outer protective component 2, both connected to the battery mounting bracket 500. The inner protective component 1 forms a protective cavity 111 with a first opening facing downward. At least a portion of the battery device 100 extends into the protective cavity 111 through the first opening. The outer protective component 2 covers the side of the inner protective component 1 that faces away from the protective cavity 111.

[0093] The battery mounting bracket 500 is a structural component fixed to the chassis 400 of the vehicle 1000. The battery unit 100 is detachably connected to the battery mounting bracket 500, facilitating subsequent replacement or maintenance operations. The battery mounting bracket 500 can be installed on the chassis 400 using bolts or welding, depending on the design requirements of the vehicle 1000. The battery unit 100 is connected to the battery mounting bracket 500 via its locking assembly 30. The locking assembly 30 may include a T-bolt 303, which passes through the mounting through hole 5013 (sometimes also called a mounting hole) of the battery mounting bracket 500, and the head of the T-bolt 303 abuts against the upward-facing surface of the battery mounting bracket 500, thereby locking the battery unit 100 to the battery mounting bracket 500.

[0094] The protective assembly 600 is a structural component used to protect the battery device 100. It isolates at least a portion of the outer surface of the battery device 100 from the external environment, thereby preventing the accumulation of foreign matter in the isolated portion. The protective assembly 600 includes an inner protective component 1 and an outer protective component 2. The inner protective component 1 may be made of plastic, and its shape may be designed to conform to the shape of the battery device 100 to improve fit and sealing. The inner protective component 1 covers at least a portion of the battery device 100 from above. The inner protective component 1 may cover a portion of the battery device 100 from above, or it may cover the entire battery device 100 from above. For example,... Figure 8 As shown, the inner protective assembly 1 includes a top wall 113 and side walls 114 surrounding the top wall 113. The upper edge of the side walls 114 connects to the outer peripheral edge of the top wall 113, and the lower edge of the side walls 114 forms a first opening. The top wall 113 covers the top of the battery device 100, and the side walls 114 cover the outer periphery of the battery device 100. A protective cavity 111 is formed between the top wall 113 and the side walls 114. The outer protective assembly 2 can be made of metal (such as sheet metal). The outer protective assembly 2 has high strength and corrosion resistance and is used to block foreign objects from entering the external environment. The outer protective assembly 2 can cover part or all of the inner protective assembly 1 from above. For example, as shown in the figure... Figure 4 As shown, the outer protective assembly 2 includes multiple protective outer plates 21, some of which cover the inner protective assembly 1 from above, and other protective outer plates 21 cover the inner protective assembly 1 from the front, rear and both sides along the vehicle width direction cd.

[0095] For example, the inner protective component 1 can cover at least part of the mounting through-hole 5013 of the battery mounting bracket 500 from the top, making it difficult for foreign objects such as dust, branches, and mud to enter the mounting through-hole 5013. The outer protective component 2 also covers the mounting through-hole 5013 of the battery mounting bracket 500 from the top, achieving double-layer protection.

[0096] For example, some mounting holes 5013 are not covered by the inner protective component 1, and the outer protective component 2 also covers all mounting holes 5013 of the battery mounting bracket 500 from the top, making it difficult for foreign objects such as dust, branches, and mud to enter the mounting holes 5013.

[0097] The vehicle 1000 provided in this application embodiment firstly features a battery mounting bracket 500 connected to the chassis 400, on which the battery device 100 is detachably mounted for easy maintenance and replacement. Secondly, a protective assembly 600 is provided to protect the battery device 100, which not only reduces the accumulation of foreign objects on the battery device 100 but also reduces the frequency of cleaning, thereby reducing cleaning costs and improving battery swapping efficiency. Furthermore, the protective assembly 600 includes an inner protective component 1 and an outer protective component 2. The inner protective component 1 has a protective cavity 111 to accommodate a portion of the battery device 100, which can reduce the direct accumulation of foreign objects on the upper surface of the battery device 100. At the same time, the outer protective component 2 covers the outside of the inner protective component 1, further blocking impacts from the external environment and the intrusion of foreign objects. Since the outer protective component 2 is located on the outer layer, it acts as the first line of defense, absorbing most of the external impact and blocking large foreign objects. This reduces the risk of damage to the inner protective component 1 and the battery device 100, helps reduce the accumulation of foreign objects in the battery device 100, improves the alignment accuracy between the battery device 100 and the battery mounting bracket 500, and enhances the stability of the battery swapping process. Furthermore, in some battery swapping scenarios, the vehicle 1000 and battery device 100 can be cleaned outside the swapping station. Specific cleaning methods include, but are not limited to, directly washing the vehicle 1000 and battery device 100 or replacing the protective assembly 600. This convenient cleaning operation further improves battery swapping efficiency.

[0098] In some embodiments, the stiffness of the outer protective component 2 is greater than that of the inner protective component 1, and the impact resistance of the outer protective component 2 is greater than that of the inner protective component 1.

[0099] Stiffness refers to the ability of a material or structure to resist deformation. The greater the stiffness, the less likely the structure is to deform. The outer protective component 2 can use materials with high stiffness (such as iron plates, steel plates, aluminum alloys, etc.), which can effectively reduce deformation caused by external impact forces, thereby protecting the inner protective component 1 and the battery device 1 from damage. The inner protective component 1 can use materials with a certain degree of elasticity (such as plastics, rubber, etc.) to absorb some impact energy and adapt to minor vibrations. By setting the outer protective component 2 to have higher stiffness, it can act as the first line of defense against impacts from foreign objects, reducing direct impact on the inner protective component 1, thus allowing the inner protective component 1 to better perform its function of protecting against foreign objects.

[0100] Impact resistance refers to the ability of a material to withstand an instantaneous impact force without breaking. In this embodiment, the outer protective component 2 is made of a material with stronger impact resistance, such as metal or composite material, enabling it to withstand greater impact forces without breaking or failing. In contrast, the inner protective component 1 focuses more on lightweighting and cushioning, and its impact resistance is relatively lower. Through the combined use of the outer protective component 2 and the inner protective component 1, the outer protective component 2 is responsible for resisting external impacts, while the inner protective component 1 is used to absorb and disperse the remaining impact energy, thereby achieving a multi-level protection effect and improving the overall protection effect of the protective assembly 600. Thus, the outer protective component 2 uses materials with higher rigidity and impact resistance, which enhances its resistance to external physical impacts. This can protect the inner protective component 1 and the battery device 100 from damage to a greater extent, and improve the stability of the entire protective assembly 600 under complex working conditions. Especially in harsh environments such as coal mines, it can significantly reduce the probability of mud, carbon ash, sand and other particulate matter depositing on the outer surface of the battery device 100, thereby extending the life of the battery device 100 and improving the battery swapping efficiency and stability.

[0101] Of course, it is understood that the stiffness or impact resistance of the outer protective component 2 is not limited to being greater than that of the inner protective component 1. In some embodiments, the stiffness of the outer protective component 2 may be less than that of the inner protective component 1, and the impact resistance of the outer protective component 2 may be less than that of the inner protective component 1.

[0102] In some embodiments, the outer protective component 2 is made of metal, and the inner protective component 1 is made of plastic.

[0103] The outer protective component 2 is made of metallic materials, such as iron plates, steel, or aluminum alloys, giving it high rigidity and impact resistance. This effectively absorbs the impact force of foreign objects in the external environment, reducing the probability of foreign objects directly intruding into the battery device 100 area. This allows the protective assembly 600 to maintain its structural integrity under various complex working conditions (such as bumpy roads and severe weather). Metallic materials are suitable for withstanding significant external impacts and also provide strong sealing and weather resistance. Furthermore, surface treatments (such as galvanizing and oxidation) can enhance the corrosion resistance of metallic materials and extend their service life. In practical applications, such as when the vehicle 1000 travels in mines, construction sites, or dusty environments, the metallic outer protective component 2 can effectively block large foreign objects (such as stones and branches) from impacting the inner protective component 1 and the battery device 100, maintaining the protective function of the inner protective component 1 for the battery device 100 and improving the overall protective effect of the protective assembly 600.

[0104] The inner protective component 1 is made of plastic materials, such as polypropylene (PP), polyethylene (PE), or other high-strength engineering plastics. It has a light weight and a certain degree of flexibility, and can deform to absorb energy when subjected to minor impacts. Compared with metal materials, plastic materials are less expensive and easier to process into complex shapes, making them suitable for manufacturing an inner protective structure that conforms to the outer contour of the battery device 100.

[0105] In this configuration, the inner protective component 1 and the outer protective component 2 form a complementary protection system. The outer protective component 2 is responsible for resisting strong external impacts, while the inner protective component 1 is used to buffer minor internal vibrations or collisions and reduce the deposition of foreign objects on the outer surface of the battery device 100. The dual-layer structure composed of the outer protective component 2 and the inner protective component 1 not only improves the overall protection level but also meets the requirements for lightweighting, helping to reduce the weight of the vehicle 1000 and improve its range performance.

[0106] Of course, it is understood that the material of the outer protective component 2 is not limited to metal, and the material of the inner protective component 1 is not limited to plastic. In some embodiments, the material of the outer protective component 2 may be a continuous fiber thermoplastic resin composite material, and the material of the inner protective component 1 may be ordinary plastic.

[0107] In some embodiments, such as Figure 3 and Figure 4 As shown, at least a portion of the outer protective component 2 completely covers the inner protective component 1 from above.

[0108] It is understood that at least a portion of the outer protective component 2 completely covers the inner protective component 1 from above, meaning that when projected onto the same projection plane in the vertical direction ef, the projection of the inner protective component 1 falls entirely within the projection range of the outer protective component 2.

[0109] In this way, by fully covering the inner protective component 1 from above with the outer protective component 2, the outer protective component 2 can shield and protect both the inner protective component 1 and the upper surface of the battery device 100, making it less likely for foreign objects to accumulate on the upper surface of the battery device 100, improving the alignment accuracy of the battery device 100 and the battery mounting bracket 500, enhancing the stability of the battery swapping process, and improving the battery swapping efficiency.

[0110] In some embodiments, such as Figure 8 and Figure 10 As shown, the top of the inner protective component 1 has a first avoidance opening 115 and a second avoidance opening 116. The top of the battery device 100 has a battery end electrical connector 10111 and a battery end water connector 10112. The battery end electrical connector 10111 and the battery end water connector 10112 are exposed through the first avoidance opening 115 and the second avoidance opening 116, respectively.

[0111] It is understandable that the battery-side electrical connector 10111 is exposed through the first recess 115, indicating that the battery-side electrical connector 10111 is visible from the outside of the inner protective assembly 1. This could mean that the entire battery-side electrical connector 10111 is located inside the inner protective assembly 1 and is positioned close to the first recess 115, or a portion of the battery-side electrical connector 10111 is located inside the inner protective assembly 1, with the other portion extending outward through the first recess 115. Similarly, the battery-side water connector 10112 is exposed through the second recess 116, indicating that the battery-side water connector 10112 is visible from the outside of the inner protective assembly 1. This could mean that the entire battery-side water connector 10112 is located inside the inner protective assembly 1 and is positioned close to the second recess 116, or a portion of the battery-side water connector 10112 is located inside the inner protective assembly 1, with the other portion extending outward through the second recess 116.

[0112] Thus, the battery-side electrical connector 10111 and battery-side water connector 10112 at the top of the battery device 100 are exposed through the first avoidance opening 115 and the second avoidance opening 116, respectively, for connection to the vehicle-side electrical connector 505 and the vehicle-side water connector 506. The outer protective component 2 completely covers the inner protective component 1 from above. That is, the outer protective component 2 covers and shields the first avoidance opening 115 and the second avoidance opening 116, as well as the battery-side electrical connector 10111 and the battery-side water connector 10112 from above, reducing the accumulation of foreign objects in these locations, which is beneficial to improving battery swapping stability, reducing the number of cleaning cycles, and thus improving battery swapping efficiency. In addition, since the battery-side electrical connector 10111 and battery-side water connector 10112 of the battery device 100 are shielded and protected by the outer protective component 2, liquid is less likely to enter these parts, allowing other parts of the battery device 100 and the protective assembly 600 to be directly rinsed with liquid, simplifying cleaning operations and improving battery swapping efficiency.

[0113] In some embodiments, such as Figure 6 and Figure 8 As shown, the portion of the battery device 100 located inside the protective cavity 111 has its outer surface covered by the inner protective component 1, except for the outer surface where the battery end electrical connector 10111 and the battery end water connector 10112 are located.

[0114] In this way, the outer surface of the battery device 100 is covered by the inner protective component 1 as much as possible, which maximizes the protection of the battery device 100, reduces the accumulation of foreign objects on the outer surface of the battery device 100, helps to improve the stability of battery swapping, and reduces the number of cleaning times.

[0115] In some embodiments, such as Figure 8 and Figure 10As shown, the battery device 100 has an upwardly protruding first protrusion 1011 and a second protrusion 1012. The first protrusion 1011 has a second protrusion 1012 on each side along the vehicle width direction cd of the vehicle 1000. The first protrusion 1011 and the second protrusion 1012 are spaced apart. The inner protective assembly 1 includes a plurality of protective covers 11, including a first protective cover 11a and a second protective cover 11b. The first protective cover 11a has a second protective cover 11b on each side along the vehicle width direction cd. The first protective cover 11a has a first avoidance opening 115 and a second avoidance opening 116. The first protrusion 1011 is located in the protective cavity 111 of the first protective cover 11a. The outer surface of the first protrusion 1011, except for the outer surface where the battery terminal electrical connector 10111 and the battery terminal water connector 10112 are located, is covered by the first protective cover 11a. The second protrusion 1012 is located in the protective cavity 111 of the second protective cover 11b. The outer surface of the second protrusion 1012 is fully covered by the second protective cover 11b.

[0116] For example, such as Figure 8 As shown, the protective cover 11 includes a top wall 113 and a side wall 114 surrounding the top wall 113. The upper edge of the side wall 114 is connected to the outer peripheral edge of the top wall 113, and the lower edge of the side wall 114 forms a first opening. The top wall 113 covers the top of the battery device 100, and the side wall 114 covers the outer peripheral side of the battery device 100.

[0117] For example, such as Figure 8 As shown, the top wall 113 of the first protective cover 11a has a first avoidance opening 115 and a second avoidance opening 116, and the side wall 114 of the first protective cover 11a completely covers the outer peripheral surface of the first protrusion 1011. The top wall 113 of the second protective cover 11b completely covers the upper surface of the second protrusion 1012, and the side wall 114 of the second protective cover 11b completely covers the outer peripheral surface of the second protrusion 1012.

[0118] Thus, a battery terminal electrical connector 10111 and a battery terminal water connector 10112 are provided on the first protrusion 1011 located in the middle position along the vehicle width direction cd. The first protective cover 11a is provided with a first avoidance opening 115 and a second avoidance opening 116 at the corresponding positions of these connectors. The other outer surfaces of the first protrusion 1011 are all covered, and the second protective cover 11b fully covers the outer surface of the second protrusion 1012. This ensures that the outer surface of the battery device 100 is covered by the inner protective component 1 as much as possible, thereby maximizing the protection effect of the battery device 100, reducing the accumulation of foreign objects on the outer surface of the battery device 100, improving battery swapping stability, and reducing the number of cleaning cycles. In addition, the first protrusion 1011, which is provided with the battery end electrical connector 10111 and the battery end water connector 10112, is disposed between the second protrusion 1012, so that the first protrusion 1011 is shielded by the second protrusion 1012 and the second protective cover 11b on both sides along the vehicle width direction cd. During the process of rinsing the battery device 100 and the protective assembly 600 from the left, right and top sides, liquid is less likely to enter the battery end electrical connector 10111 and the battery end water connector 10112, thereby improving the safety and reliability of rinsing the battery device 100.

[0119] In some embodiments, such as Figures 6 to 10 As shown, the battery mounting bracket 500 includes multiple mounting beams 501. The mounting beams 501 extend along the width direction cd of the vehicle 1000 and are connected to the longitudinal beams 401 of the chassis 400. The bottom edge of the mounting beams 501 forms a mounting flange 5011. The mounting flange 5011 forms multiple mounting through holes 5013 extending along the vertical direction ef of the vehicle 1000. The battery device 100 includes a locking assembly 30. The locking assembly 30 passes through the mounting through holes 5013 and is detachably connected to the mounting flange 5011. The inner protective assembly 1 includes a protective cover 11. The protective cover 11 forms a protective cavity 111. The protective cover 11 forms a connecting flange 112 bent away from the protective cavity 111 at the edge of the first opening. The connecting flange 112 is connected to the mounting flange 5011.

[0120] Mounting beam 501 is a transverse support component constituting the main structure of battery mounting bracket 500, used to support and fix battery device 100. Mounting beam 501 can be made of high-strength metal materials, such as steel or aluminum alloy, to ensure sufficient rigidity and stability. The number and arrangement of mounting beams 501 are customized according to the structure of vehicle chassis 400 and the dimensions of battery device 100. For example, in an electric commercial vehicle, three pairs of mounting beams 501 can be provided, with two beams 501 in each pair arranged parallel to each other and spaced apart, located on opposite sides of battery device 100 and connected to the opposite sides of battery device 100. The mounting flange 5011 is a structure formed by bending the bottom edge of the mounting beam 501. It is used to connect with the locking assembly 30 of the battery device 100. For example, the T-bolt 303 of the locking assembly 30 passes through the mounting through hole 5013. The head of the T-bolt 303 of the locking assembly 30 abuts against the upper surface of the mounting flange 5011 to achieve locking. After the head of the T-bolt 303 rotates a certain angle (e.g., 90°), the head of the T-bolt 303 can be withdrawn from the mounting through hole 5013 in the vertical direction ef, thereby achieving unlocking. The mounting through hole 5013 is a hole that passes through the mounting flange 5011. For example, the mounting through hole 5013 is a rectangular or elliptical hole for inserting a T-bolt 303 or other fasteners. When the length direction of the head of the T-bolt 303 is consistent with the length direction of the mounting through hole 5013, the head of the T-bolt 303 can pass through the mounting through hole 5013 along the vertical direction ef. After the T-bolt 303 is rotated at a certain angle, when the length direction of the head is consistent with the width direction of the mounting through hole 5013, the projection of the head along the vertical direction ef exceeds the projection of the mounting through hole 5013, and the head cannot pass through the mounting through hole 5013. The head abuts against the upper surface of the mounting flange 5011 to achieve locking.

[0121] The vehicle width direction (cd) refers to the lateral direction (left-right direction) of the vehicle 1000, which is usually perpendicular to the longitudinal direction (ab) of the vehicle 1000. By extending the mounting beam 501 along the vehicle width direction (cd) and connecting it to the longitudinal beam 401 of the chassis 400, the lateral stability of the entire battery mounting bracket 500 can be effectively improved, reducing the impact of lateral forces generated by bumps or turns during vehicle 1000 operation on the battery unit 100. The connection between the mounting beam 501 on the vehicle width direction (cd) and the longitudinal beam 401 of the chassis 400 can be achieved by welding, bolting, or riveting.

[0122] The locking assembly 30 is a mechanical structure for quickly connecting and disconnecting the battery device 100 from the battery mounting bracket 500. For example, Figures 10 to 12As shown, the locking assembly 30 includes a sleeve 301, a threaded component 302, and a T-bolt 303. The sleeve 301 is fixedly connected to the housing 102 of the battery box. The threaded component 302 has a threaded hole. Part of the threaded component 302 is located inside the sleeve 301, and the rest is located outside the sleeve 301. The part of the threaded component 302 located outside the sleeve 301 is used to cooperate with the battery replacement device (sometimes also called a battery swapping trolley). Part of the T-bolt 303 is located inside the sleeve 301 and passes through the threaded hole of the threaded component 302. The head and part of the shank of the T-bolt 303 are located outside the sleeve 301. The battery replacement device can drive the threaded component 302 to rotate, and also drive the T-bolt 303 to rotate. During the process of removing the battery device 100 from the chassis 400, the battery replacement device engages with the part of the threaded part 302 located outside the sleeve 301. By driving the threaded part 302 and the T-bolt 303 to rotate, the head of the T-bolt 303 rotates 90°, and then lowers with the battery device 100, so that the head of the T-bolt 303 exits from the mounting through hole 5013 of the mounting flange 5011, thereby removing the battery device 100. During the installation of the battery device 100 onto the chassis 400, the battery replacement device engages with the portion of the threaded component 302 located outside the sleeve 301. By driving the threaded component 302 and the T-bolt 303 to rise to pass through the mounting through hole 5013 of the mounting flange 5011, and after rotating the T-bolt 303 by 90°, the projection of the head of the T-bolt 303 in the vertical direction ef exceeds the projection of the mounting through hole 5013. The T-bolt 303 then descends until its head abuts against the upper surface of the mounting flange 5011, thus realizing the installation of the battery device 100 on the chassis 400.

[0123] For example, such as Figure 12 and Figure 13 As shown, the box wall of the box body 102 has a locking mounting hole, the sleeve 301 is fixed in the locking mounting hole, part of the T-bolt 303 is located outside the box body 102, and the shank of the T-bolt 303 is fitted with a dustproof sleeve 304, which seals the gap between the shank and the wall of the locking mounting hole.

[0124] The protective cover 11 is a physical barrier covering the top or outer periphery of the battery device 100, primarily used to prevent external foreign objects from contacting the battery device 100. The protective cover 11 can be made of lightweight, high-strength materials, such as plastic, metal, or composite materials, possessing good impact resistance and corrosion resistance. The shape and size of the protective cover 11 can match the outer contour of the battery device 100, allowing it to cover critical areas, such as the cover 101 of the battery case. The protective cavity 111 refers to the cavity formed inside the protective cover 11, which accommodates part or all of the battery device 100 and provides protection, serving to prevent dust and moisture, thereby improving the cleanliness, battery swapping efficiency, and battery swapping stability of the battery device 100.

[0125] For example, such as Figure 6 and Figure 9 As shown, the mounting beam 501 includes a beam body 5012 and a mounting flange 5011 connected to the bottom end of the beam body 5012. The top end of the beam body 5012 extends beyond the upper surface of the protective cover 11, and the beam body 5012 provides a certain degree of protection for the protective cover 11.

[0126] For example, such as Figure 8 As shown, the protective cover 11 includes a top wall 113 and a side wall 114 surrounding the top wall 113. The upper edge of the side wall 114 is connected to the outer peripheral edge of the top wall 113. The top wall 113 covers the battery device 100, and the side wall 114 covers the outer peripheral side of the battery device 100.

[0127] Thus, by setting multiple mounting beams 501 extending along the vehicle width direction cd and connecting them to the longitudinal beams 401 of the chassis 400, the structural strength and stability of the battery mounting bracket 500 are improved. The mounting flanges 5011 at the bottom of the mounting beams 501 form multiple mounting through holes 5013, providing reliable fixing points for the locking components 30 of the battery device 100, thereby improving the installation stability of the battery device 100. Simultaneously, the connecting flanges 112 at the edge of the protective cover 11 connect with the mounting flanges 5011, realizing the connection between the protective cover 11 and the battery mounting bracket 500. That is, the mounting flanges 5011 also serve as mounting points for both the battery device 100 and the protective cover 11. This not only simplifies the structure of the mounting beams 501 but also allows the protective cover 11 to cover the interface between the battery device 100 and the mounting flanges 5011, reducing gaps and effectively reducing the deposition of foreign matter into the battery device 100, thereby further improving the protective effect.

[0128] Of course, it is understood that the protective cover 11 is not limited to being connected to the mounting flange 5011 of the mounting beam 501. In some embodiments, the mounting beam 501 also forms a connection structure specifically for connecting the protective cover 11, which is different from the mounting flange 5011.

[0129] In some embodiments, such as Figures 14 to 17 As shown, the connecting flange 112 is connected to the upper or lower surface of the mounting flange 5011, and a locking assembly 30 is inserted through a portion of the mounting through hole 5013, while the remaining portion of the mounting through hole 5013 is covered by the connecting flange 112.

[0130] For example, the inner protective assembly 1 includes a plurality of protective covers 11, with the connecting flange 112 of some of the protective covers 11 connected to the upper surface of the mounting flange 5011 of the mounting beam 501, and the connecting flange 112 of another portion of the protective covers 11 connected to the lower surface of the mounting flange 5011 of the mounting beam 501.

[0131] For example, at least two mounting beams 501 have the same structure. Mounting beams 501 with the same structure can be manufactured using the same set of molds, which helps to improve production efficiency and reduce production costs.

[0132] It should be noted that there are multiple mounting beams 501, which are connected to different positions of the longitudinal beams 401 of the chassis 400 and correspond to different mounting beams of the battery device 100. In order to improve the versatility of the mounting beams 501 in different installation positions, the mounting through holes 5013 of the mounting beams 501 are usually redundantly set. That is, some of the mounting through holes 5013 on each mounting beam 501 are engaged with the locking components 30 of the battery device 100, while the remaining mounting through holes 5013 are not engaged with the locking components 30. In this way, by using the connecting flange 112 of the protective cover 11 to cover these mounting through holes 5013 that are not engaged with the locking components 30, the probability of foreign objects falling onto the battery device 100 through the mounting through holes 5013 can be reduced, further improving the protection effect and thus improving the stability of battery swapping.

[0133] For example, the connecting flange 112 avoids the mounting through hole 5013 through which the locking component 30 is provided, and covers the mounting through hole 5013 that does not cooperate with the locking component 30.

[0134] For example, the connecting flange 112 is connected to the mounting flange 5011 by bolts, welding or riveting.

[0135] For example, the connecting flange 112 abuts against the upper or lower surface of the mounting flange 5011.

[0136] In this way, by covering the unused mounting through holes 5013 with the connecting flange 112, the probability of foreign matter depositing on the battery device 100 through these mounting through holes 5013 is reduced, improving the protection effect and thus improving the stability of battery swapping. Moreover, the area of ​​the connecting flange 112 facing the mounting flange 5011 is relatively large, which helps to improve the strength of the connecting flange 112 and the connection strength between the connecting flange 112 and the mounting flange 5011.

[0137] Of course, it is understood that the connecting flange 112 is not limited to covering unused mounting through holes 5013. In some embodiments, the connecting flange 112 is connected to the mounting flange 5011 and avoids all mounting through holes 5013.

[0138] In some embodiments, such as Figures 14 to 17 As shown, the protective assembly 600 also includes a protective shell 3, which is connected to the upper surface of the mounting flange 5011 and covers the mounting through hole 5013 through which the locking component 30 is provided. The portion of the locking component 30 that protrudes from the top of the mounting through hole 5013 is accommodated within the protective shell 3.

[0139] For example, the protective shell 3 has a downward-facing second opening, and the other sides of the protective shell 3 are blocked by shell walls. The second opening of the protective shell 3 is closed by the mounting flange 5011 to form a closed space, and the portion of the locking assembly 30 that protrudes from the top of the mounting through hole 5013 is accommodated in the closed space.

[0140] For example, the protective shell 3 has outwardly folded flaps 31 formed on the two opposite edges of the second opening. Metal bushings 32 are embedded in the flaps 31. The metal bushings 32 are fitted with fasteners such as bolts, and the fasteners are locked to the mounting flange 5011.

[0141] Understandably, the space inside the protective housing 3 is sufficient for the head of the T-bolt 303 to rotate, thereby reducing the impact of the protective housing 3 on the locking function of the battery device 100. Furthermore, the space inside the protective housing 3 is also large enough in the vertical direction ef to allow the T-bolt 303 to move in the vertical direction ef. The specific dimensions are determined based on the specific dimensions of the locking assembly 30 and are not specifically limited here.

[0142] For example, the protective shell 3 is a one-piece molded structure.

[0143] For example, the protective shell 3 may be made of, but is not limited to, plastic, fiber composite materials, metal materials, etc.

[0144] For example, the protective shell 3 can be separated from the protective cover 11 and manufactured separately; the protective shell 3 can also be connected to the protective cover 11 and the two can be connected as one piece, which can be manufactured separately and then combined, or it can be molded as one piece.

[0145] Thus, the protective housing 3 further strengthens the protection of the locking assembly 30, the mounting through hole 5013, and the surrounding area, reducing the intrusion of foreign objects and their blockage of the mounting through hole 5013. The locking assembly 30 is housed within the protective housing 3, which not only reduces the probability of dust settling on the locking assembly 30, but also reduces the chance of the locking assembly 30 being impacted by external objects, improving the reliability of the locking mechanism and the stability of the battery swapping process.

[0146] Of course, it is understood that the protective assembly 600 is not limited to including the protective housing 3, and in some embodiments, the protective assembly 600 does not include the protective housing 3.

[0147] In some embodiments, such as Figure 15 and Figure 17 As shown, the battery mounting bracket 500 also includes a first gasket 503, which is connected to the upper side of the mounting flange 5011 and is arranged around the mounting through hole 5013 through which the locking assembly 30 is provided. The locking assembly 30 abuts against the upper surface of the first gasket 503, and the protective shell 3 abuts against the upper surface of the first gasket 503.

[0148] The first gasket 503 can be made of metal or high-strength plastic, and has a certain degree of elasticity and wear resistance. The first gasket 503 is connected to the mounting flange 5011 by screws or other fixing methods, and is arranged around the mounting through hole 5013 to support, dampen and protect the mounting flange 5011.

[0149] For example, the protective shell 3 and the first gasket 503 are assembled in the same hole on the mounting flange 5011.

[0150] It is understandable that the mounting through hole 5013 of the locking assembly 30 needs to be equipped with a first gasket 503, and the mounting through hole 5013 of the locking assembly 30 does not need to be equipped with a first gasket 503.

[0151] Thus, the first shim 503 reduces wear on the mounting flange 5011 caused by repeated unlocking and unlocking operations of the locking assembly 30, which helps extend its service life. Furthermore, the first shim 503 is also placed between the mounting flange 5011 and the protective shell 3, which helps improve the reliability of the installation of the protective shell 3, reduces loosening or damage caused by vibration or external impact, improves the stability of the overall structure, and thus improves the protective effect of the protective shell 3, further enhancing the stability of battery swapping.

[0152] Of course, it is understood that the protective shell 3 and the locking assembly 30 are not limited to sharing the first gasket 503. In some embodiments, the protective shell 3 and the mounting flange 5011 are in direct contact, and there is no first gasket 503 between them.

[0153] In some embodiments, such as Figure 7 and Figure 9 As shown, the protective cover 11 is provided with mounting beams 501 on the front and rear sides along the longitudinal direction ab of the vehicle 1000. The battery mounting bracket 500 also includes a side beam 502, which extends along the longitudinal direction ab and connects with the mounting beams 501 provided on the front and rear sides of the protective cover 11. The side beam 502 blocks one side of the protective cover 11 along the vehicle width direction cd.

[0154] It should be noted that the side beam 502 blocks one side of the protective cover 11 along the vehicle width direction cd, indicating that the side beam 502 is located on one side of the protective cover 11 along the vehicle width direction cd, and the side beam 502 is located on the outside of the protective cover 11. When projected along the vehicle width direction cd, the orthographic projection of the side beam 502 and the orthographic projection of the protective cover 11 have an overlapping part.

[0155] It is understood that the battery device 100 is provided with mounting beams 501 on the front and rear sides along the longitudinal direction ab of the vehicle 1000, and the battery device 100 is locked to the mounting beams 501 on its front and rear sides.

[0156] For example, each protective cover 11 has a mounting beam 501 on its front and rear sides, and a connecting flange 112 is formed on both the front and rear sides of the protective cover 11. The connecting flanges 112 formed on the front and rear edges of the protective cover 11 are respectively connected to the mounting flanges 5011 of their respective adjacent mounting beams 501.

[0157] It should be noted that when multiple protective covers 11 are provided, side beams 502 can be provided on one or both sides of some protective covers 11 along the vehicle width direction cd, while side beams 502 are not provided on the other side of some protective covers 11 along the vehicle width direction cd; or side beams 502 can be provided on one or both sides of all protective covers 11 along the vehicle width direction cd.

[0158] For example, both ends of the side beam 502 are fixed to the two mounting beams 501 by fasteners such as bolts.

[0159] By providing mounting beams 501 on the front and rear sides of the protective cover 11, the battery device 100 can be securely connected to the battery mounting bracket 500, and the connection between the protective cover 11 and the battery mounting bracket 500 can be made more secure. This reduces the possibility of protection failure due to long-term use or external impact, thereby reducing the probability of battery swapping failure due to foreign object accumulation, and thus significantly improving battery swapping efficiency and stability. Furthermore, the side beams 502 enhance the overall structural strength of the battery mounting bracket 500, especially its support capacity in the front-rear direction ab. Simultaneously, the side beams 502, blocking one side of the protective cover 11, reduce the impact of foreign objects from the left and right sides of the vehicle 1000 on the protective cover 11, ensuring that the battery device 100 is adequately protected under various operating conditions.

[0160] Of course, it is understood that the battery mounting bracket 500 is not limited to including the side beam 502, and in some embodiments, the battery mounting bracket 500 does not include the side beam 502.

[0161] Of course, it is understood that the battery mounting bracket 500 includes a side beam 502. The side beam 502 is not limited to being located on one side of the protective cover 11 along the vehicle width direction cd. In some embodiments, the side beam 502 is located inside the protective cavity 111 of the protective cover 11 and on one side of the battery device 100 along the vehicle width direction cd.

[0162] In some embodiments, such as Figure 3 and Figure 4 As shown, the outer protective assembly 2 includes multiple protective outer plates 21, which are connected to the mounting beam 501 and the side beam 502, and cover the protective cover 11, the mounting beam 501 and the side beam 502 on the side facing away from the protective cavity 111.

[0163] It is understood that the battery mounting bracket 500 is located outside the inner protective component 1, and the outer protective component 2 is located outside both the battery mounting bracket 500 and the inner protective component 1.

[0164] Multiple protective outer panels 21 refer to the main structural components constituting the outer protective assembly 2. These panels can be made of materials with sufficient strength and weather resistance, such as metal, composite materials, or high-strength plastics. For example, each protective outer panel 21 is connected to the mounting beam 501 and the side beam 502 via bolts, clips, or other fixing methods to form an integrated protective system. The multiple protective outer panels 21 can be connected by splicing, fitting, welding, or threaded connections.

[0165] By setting multiple protective outer plates 21 and connecting them to the mounting beam 501 and side beam 502, and covering the protective cover 11, mounting beam 501, and side beam 502 on the side facing away from the protective cavity 111, the entry of foreign objects from the external environment into the battery device 100 area can be reduced, thereby improving the cleanliness of the battery device 100, increasing battery swapping efficiency and stability, and extending the service life of the battery device 100. Furthermore, the multiple protective outer plates 21 expand the coverage area of ​​the outer protective component 2, allowing it to more comprehensively wrap around the protective cover 11, mounting beam 501, and side beam 502, forming a continuous protective barrier. This not only improves the overall protective performance but also enhances the neatness and aesthetics of the appearance.

[0166] In some embodiments, such as Figure 4 and Figure 19 As shown, the protective assembly 600 also includes a fixed frame 4, which includes a plurality of first beams 41 extending along the vehicle width direction cd and a plurality of second beams 42 extending along the front-rear direction ab. The first beams 41 are each connected to the top of the plurality of mounting beams 501, and the two ends of the second beams 42 overlap the top of the mounting beams 501 and are connected to the first beams 41. At least part of the protective outer plate 21 is connected to the first beams 41 and the second beams 42.

[0167] The fixed frame 4 refers to the basic frame used to support and fix the entire outer protective component 2, and can be made of high-strength metal materials (such as steel or aluminum alloy). For example, the fixed frame 4 forms a grid structure by setting multiple first beams 41 and multiple second beams 42 to enhance compressive and bending resistance. The first beams 41 in the fixed frame 4 extend along the vehicle width direction cd, mainly for lateral support; the second beams 42 in the fixed frame 4 extend along the longitudinal direction ab. Connecting the first beams 41 to the mounting beams 501 effectively distributes the load and improves the overall structural integrity; overlapping the two ends of the second beams 42 onto the mounting beams 501 and connecting them to the first beams 41 further enhances the structural stability and load-bearing capacity.

[0168] Thus, the fixed frame 4 provides more mounting points for the protective outer plate 21, improving its fixing reliability. At the same time, the fixed frame 4 also enhances the structural rigidity of the battery mounting bracket 500, which helps to disperse and absorb external impact forces, thereby better protecting the battery device 100 from damage.

[0169] Of course, it is understood that the protective assembly 600 is not limited to including the fixed frame 4. In some embodiments, the protective assembly 600 does not include the fixed frame 4, and the protective outer plate 21 is directly connected to the battery mounting bracket 500 by fasteners such as bolts.

[0170] In some embodiments, such as Figure 6 , Figure 7 and Figure 10As shown, the plurality of mounting beams 501 include at least two first mounting beams 501a and at least four second mounting beams 501b. The first mounting beams 501a are connected between two longitudinal beams 401 of the chassis 400. The at least two first mounting beams 501a are spaced apart along the longitudinal direction ab. Each longitudinal beam 401 is connected to at least two second mounting beams 501b on the side facing away from the other longitudinal beam 401 along the vehicle width direction cd. The at least two second mounting beams 501b connected to the same longitudinal beam 401 are spaced apart along the longitudinal direction ab. The inner protective assembly 1 includes a plurality of protective covers 11. The plurality of protective covers 11 include at least one first protective cover 11a and at least two... A second protective cover 11b is provided. The first protective cover 11a is connected between adjacent first mounting beams 501a along the front-rear direction ab, and the second protective cover 11b is connected between adjacent second mounting beams 501b along the front-rear direction ab. The battery device 100 has an upwardly protruding first protrusion 1011 and a second protrusion 1012. The first protrusion 1011 has a second protrusion 1012 on each side along the vehicle width direction cd. The first protrusion 1011 and the second protrusion 1012 are spaced apart along the vehicle width direction cd. The first protrusion 1011 extends into the first protective cover 11a, and the second protrusion 1012 extends into the second protective cover 11b.

[0171] A protrusion refers to a localized raised structure formed on the top of the battery device 100, typically designed to accommodate internal component layout or improve heat dissipation. The first protrusion 1011 and the second protrusion 1012 correspond to different mounting areas, with the first protrusion 1011 located in the center and the second protrusions 1012 distributed on both sides. The first protrusion 1011 and the second protrusion 1012 are configured to extend into their respective protective covers 11, thereby achieving a tighter fit and protective effect.

[0172] For example, the battery device 100 includes a battery box and a battery cell assembly 20 housed in the battery box. The battery box includes a box body 102 and a box cover 101 covering the top of the box body 102. The box cover 101 has a first protrusion 1011 protruding from the side opposite to the box body 102 and two second protrusions 1012 located on opposite sides of the first protrusion 1011. A first recessed space is formed on the inner side of the box cover 101 corresponding to the first protrusion 1011, and a second recessed space is formed on the inner side of the box cover 101 corresponding to the second protrusion 1012. The first recessed space and the second recessed space together with the space inside the box body 102 constitute the receiving cavity of the battery box. The receiving cavity of the battery box houses the battery cell assembly 20, the battery management system (BMS), and the battery thermal management system, etc. For example, at least a portion of the battery management system (BMS) and at least a portion of the battery thermal management system are disposed in the first recessed space, and a battery terminal electrical connector 10111 and a battery terminal water connector 10112 are disposed on the top wall of the first protrusion 1011.

[0173] For example, for each battery device 100, there is a first protective cover 11a and two second protective covers 11b. The two second protective covers 11b are respectively located on opposite sides of the first protective cover 11a along the vehicle width direction cd. The first protective cover 11a covers the first protrusion 1011, and the two second protective covers 11b respectively cover the two second protrusions 1012.

[0174] It should be noted that the number of battery devices 100 in the vehicle 1000 can be one, two, three or more, and no specific limitation is made here. For example, there are two or more battery devices 100, and the two or more battery devices 100 are arranged sequentially along the front-rear direction ab of the vehicle 1000.

[0175] For example, the vehicle 1000 has three battery devices 100. The battery mounting bracket 500 includes four first mounting beams 501a spaced apart along the front-rear direction ab, four second mounting beams 501b spaced apart along the front-rear direction ab, and another four second mounting beams 501b spaced apart along the front-rear direction ab. The two sets of second mounting beams 501b are respectively arranged on opposite sides of the first mounting beams 501a along the vehicle width direction cd. A first protective cover 11a is provided between adjacent first mounting beams 501a along the front-rear direction ab, and a second protective cover 11b is provided between adjacent second mounting beams 501b along the front-rear direction ab. Thus, three first protective covers 11a and six second protective covers 11b are formed, which can protect the three battery devices 100 when they are installed in the battery mounting bracket 500.

[0176] For example, the shape of the first protrusion 1011 is adapted to the shape and size of the protective cavity 111 of the first protective cover 11a, and the shape of the second protrusion 1012 is adapted to the shape and size of the protective cavity 111 of the corresponding second protective cover 11b.

[0177] In this way, by setting multiple mounting beams 501 and multiple protective covers 11, zoned protection of different parts of the battery device 100 is achieved, so that each protrusion can be adapted to the inner wall of the protective cavity 111 of its corresponding protective cover 11, thus achieving a better protective effect.

[0178] In some embodiments, such as Figures 8 to 10 As shown, the battery mounting bracket 500 also includes a connector mounting plate 504 and a vehicle-end electrical connector 505 and a vehicle-end water connector 506 mounted on the connector mounting plate 504. The connector mounting plate 504 is connected between adjacent first mounting beams 501a. A first protective cover 11a is located on the lower side of the connector mounting plate 504 and is connected to the connector mounting plate 504. The first protective cover 11a forms a first avoidance opening 115 and a second avoidance opening 116. A first protrusion 1011 is provided with a battery-end electrical connector 10111 and a battery-end water connector 10112. The battery-end electrical connector 10111 is connected to the vehicle-end electrical connector 505 through the first avoidance opening 115, and the battery-end water connector 10112 is connected to the vehicle-end water connector 506 through the second avoidance opening 116.

[0179] For example, the connecting flange 112 of the first protective cover 11a is located on the lower side of the mounting flange 5011 of the first mounting beam 501a and is connected, and the connector mounting plate 504 abuts against and is connected to the upper side of the mounting flange 5011 of the first mounting beam 501a.

[0180] It is understandable that the first protective cover 11a is located on the lower side of the connector mounting plate 504, so that the first protective cover 11a is installed from bottom to top in the mounting direction of the battery mounting bracket 500.

[0181] For example, the connecting flange 112 of the second protective cover 11b is located on the upper side of the mounting flange 5011 of the second mounting beam 501b and is connected thereto, and the mounting direction of the second protective cover 11b is from top to bottom.

[0182] For example, the top wall of the first protective cover 11a is fixedly connected to the connector mounting plate 504 by fasteners such as bolts.

[0183] Thus, the connector mounting plate 504 provides a stable mounting platform for the vehicle-side electrical connector 505 and the vehicle-side water connector 506, enabling a reliable connection between them and the battery device 100. The vehicle-side electrical connector 505, located on the connector mounting plate 504, connects to the battery-side electrical connector 10111 of the battery device 100 via the first avoidance opening 115, achieving a circuit connection. The vehicle-side water connector 506, also located on the connector mounting plate 504, connects to the battery-side water connector 10112 of the battery device 100 via the second avoidance opening 116, achieving a water circuit connection. Furthermore, since many wires and water pipes need to be arranged above the connector mounting plate 504, a first protective cover 11a is provided below the connector mounting plate 504. This reduces the impact on the wires and water pipes, minimizes the number of openings in the first protective cover 11a, and allows the first protective cover 11a to cover the first protrusion 1011 as large an area as possible, further improving the protective effect and enhancing the stability of battery swapping.

[0184] In some embodiments, such as Figure 9 As shown, the first mounting beam 501a has a wire hole 5014 that extends through the beam in the front-rear direction ab.

[0185] For example, the first mounting beam 501a is formed with a plurality of wire holes 5014.

[0186] For example, the wiring harness and conduit extend from the outside through the wire hole 5014 into the space between the outer protective component 2 and the first protective cover 11a, and are connected to the vehicle-end electrical connector 505 and the vehicle-end water connector 506 respectively. The wiring harness and conduit are connected to the vehicle's electrical equipment and water supply equipment respectively.

[0187] Thus, the placement of the wire through hole 5014 facilitates the laying of wire harnesses and conduits, reducing the risk of malfunctions caused by wire tangling or jamming. Simultaneously, the through-hole design of the wire through hole 5014 also aids in heat dissipation and ventilation, reducing the impact of localized temperature rise on the battery device 100, thereby improving the operating efficiency of the battery device 100. Furthermore, the placement of the wire through hole 5014 also contributes to weight reduction.

[0188] Of course, it is understood that the first mounting beam 501a is not limited to forming a wire hole 5014. In some embodiments, the first mounting beam 501a does not form a wire hole 5014.

[0189] In some embodiments, such as Figure 9 As shown, the first mounting beam 501a is connected to two longitudinal beams 401 at both ends along the vehicle width direction cd, and the second mounting beam 501b is connected to the side of the longitudinal beam 401 facing away from the first mounting beam 501a at one end along the vehicle width direction cd, and to the side beam 502 at the other end.

[0190] Understandably, the second protective cover 11b is provided with a side beam 502 on its side.

[0191] For example, at least two of the first mounting beams 501a have the same structure.

[0192] For example, at least two of the second mounting beams 501b have the same structure.

[0193] In this way, through a reasonable connection method, a stable square frame structure is formed between the mounting beam 501 and the longitudinal beam 401 and side beam 502 of the chassis 400, which improves the overall rigidity and deformation resistance of the battery mounting bracket 500. This not only enhances the load-bearing capacity of the battery mounting bracket 500, but also optimizes the stress distribution, which helps to extend its service life. In addition, this structure is more suitable for installing square battery devices 100.

[0194] In some embodiments, such as Figure 6 and Figure 7 As shown, the protective assembly 600 also includes a gap-blocking assembly 5. The inner protective assembly 1 has a gap-blocking assembly 5 at the bottom edge position on both sides along the vehicle width direction cd. The gap-blocking assembly 5 covers part of the gap between the inner protective assembly 1 and the battery device 100.

[0195] Thus, the gap-blocking component 5 covers the gap between the inner protective component 1 and the battery device 100 on opposite sides along the vehicle width direction cd, reducing the intrusion of foreign objects from the gap. Since foreign objects are more likely to approach the left and right sides of the battery device 100, the gap-blocking component 5 is set here to reduce the chance of foreign objects approaching the battery device 100, especially the water mist penetration or fine particle accumulation that may be caused by high-pressure water gun washing during car washing, thereby improving the cleanliness of the battery device 100 and improving the stability of battery swapping.

[0196] In some embodiments, such as Figure 6 and Figure 7 As shown, the protective assembly 600 also includes a gap-blocking assembly 5, which is located at the bottom edge of the side beam 502 and covers part of the gap between the second protective cover 11b and the battery device 100.

[0197] For example, the bottom edges of the two side beams 502 on both sides of the battery device 100 along the vehicle width direction cd are each provided with a gap-blocking assembly 5.

[0198] The gap-blocking assembly 5 is a structural component located at the bottom edge of the side beam 502, used to cover part of the gap between the second protective cover 11b and the battery device 100. The gap-blocking assembly 5 can be connected to the side beam 502 or to other components near the side beam 502 (such as the lower edge of the second protective cover 11b), as long as the gap-blocking assembly 5 is located near the bottom edge of the side beam 502. The gap-blocking assembly 5 can be made of materials with a certain degree of flexibility and sealing properties, such as rubber strips, foam strips, or felt, which can reduce the entry of foreign objects such as dust, mud, and gravel into the protective cavity 111 through the gap. The gap-blocking assembly 5 can be fixed to the side beam 502 by means of adhesive, clips, or screws, making it difficult for the gap-blocking assembly 5 to fall off or shift during vehicle 1000 operation.

[0199] Thus, the gap-blocking assembly 5 covers the gap between the protective cover 11 and the battery device 100 on both sides along the vehicle width direction cd, reducing the intrusion of foreign objects from the gap. Since foreign objects are more likely to approach the left and right sides of the battery device 100, the gap-blocking assembly 5 is set here to reduce the probability of foreign objects approaching the battery device 100, improve the cleanliness of the battery device 100, and improve the stability of battery swapping.

[0200] Of course, it is understood that the protective assembly 600 is not limited to including the gap-blocking component 5, and in some embodiments, the protective assembly 600 does not include the gap-blocking component 5.

[0201] In some embodiments, such as Figure 6 and Figure 10 As shown, the battery device 100 has an upward-facing edge surface 1013 that surrounds the outer periphery of the first protrusion 1011 and the second protrusion 1012, and the gap assembly 5 abuts against the edge surface 1013.

[0202] For example, the edge region of the upper surface of the cover 101 of the battery box 10 is the aforementioned edge surface 1013. The edge surface 1013 can be used for fasteners such as bolts to achieve connection with the box body 102.

[0203] In this way, the tight fit between the gap-blocking assembly 5 and the edge surface 1013 of the battery device 100 enhances the protective effect, reduces the probability of foreign objects intruding from the edge, thereby improving the smoothness of the battery swapping process and reducing the problem of locking failure caused by the accumulation of foreign objects.

[0204] Of course, it is understood that the gap-sealing assembly 5 is not limited to abutting against the upward edge surface 1013 of the battery device 100. In some embodiments, the gap-sealing assembly 5 may abut against the surface of the second protrusion 1012 facing the left or right side of the vehicle 1000, or against the surface of the housing 102 facing the left or right side of the vehicle 1000.

[0205] In some embodiments, such as Figure 6 and Figure 7 As shown, the gap-blocking assembly 5 includes a brush 51, which is connected to the lower edge of the side beam 502 and abuts against the edge surface 1013.

[0206] Brush 51, as part of the gap-blocking assembly 5, is made of soft and elastic bristles, such as nylon or polyester fiber. The length and density of brush 51 are designed according to the space dimensions and protection requirements of the actual installation location, ensuring it effectively blocks foreign objects from entering without interfering with normal battery swapping operations. Brush 51 can be installed in a fixed or detachable manner for easy maintenance and replacement. The connection between brush 51 and the lower edge of the side beam 502 can be achieved through clips, screws, or other fasteners to improve the stability of brush 51. The contact between brush 51 and the edge surface 1013 means that the end of brush 51 is tightly pressed against the edge surface 1013, forming a physical barrier to reduce the entry of dust, mud, gravel, and other foreign objects from the side into the area of ​​the battery device 100 covered by the protective cover 11.

[0207] Thus, the brush 51, utilizing its elastic properties, forms a tight contact with the edge surface 1013, providing a physical barrier that effectively reduces the intrusion of foreign objects from the side. This is especially beneficial during car washes, where high-pressure water jets may cause water mist penetration or the accumulation of fine particles. This embodiment of the application can improve battery swapping efficiency and stability, and extend the service life of the battery device 100 and related structures. Furthermore, the brush 51 also acts as a buffer, reducing the impact on the battery device 100 when the vehicle 1000 travels on bumpy roads, further enhancing overall protection performance.

[0208] In some embodiments, such as Figure 6 and Figure 7 As shown, the gap-blocking assembly 5 includes an elastic shielding strip 52, which is connected to the lower edge of the side of the second protective cover 11b away from the first protective cover 11a, and the elastic shielding strip 52 abuts against the edge surface 1013.

[0209] The elastic shielding strip 52 is a strip-shaped component made of a flexible material, used to achieve flexible sealing and cushioning. The elastic shielding strip 52 can be made of rubber, silicone, or other flexible polymer materials, capable of adapting to different shapes or slightly varied gap structures, and deforming under external force to maintain a good fit with the edge surface 1013. The elastic shielding strip 52 reduces wear or damage that may result from hard contact. The connection between the elastic shielding strip 52 and the second protective cover 11b can be achieved through adhesive bonding, snap-fit ​​fixing, or embedded assembly. Thus, the elastic shielding strip 52 enables the gap-blocking assembly 5 to have a certain buffering capacity and adaptability, and can automatically adjust the fit with the edge surface 1013, thereby maintaining a good protective effect in different working scenarios, and further improving the cleanliness, battery swapping efficiency and battery swapping stability of the battery device 100.

[0210] In some embodiments, such as Figure 3 and Figure 4 As shown, the outer protective assembly 2 includes multiple protective outer plates 21. The multiple protective outer plates 21 include a first protective outer plate 21a, a second protective outer plate 21b, and a third protective outer plate 21c. The first protective outer plate 21a is located above the first mounting beam 501a and covers the first protective cover 11a. The second protective outer plate 21b is located above the second mounting beam 501b and covers the second protective cover 11b. The front side, rear side, and side facing away from the longitudinal beam 401 along the vehicle width direction cd of the second protective cover 11b are all covered by the third protective outer plate 21c. The third protective outer plate 21c is located on the side of the second mounting beam 501b facing away from the second protective cover 11b.

[0211] For example, the protective outer panel 21 is made of iron plate, aluminum plate or steel plate, etc.

[0212] For example, multiple protective outer panels 21 are connected to each other by fasteners such as bolts.

[0213] For example, the first protective outer plate 21a covers the top of the first mounting beam 501a, the second protective outer plate 21b covers the top of the second mounting beam 501b, and the third protective outer plate 21c covers the side of the second mounting beam 501b facing away from the second protective cover 11b.

[0214] For example, the two ends of the first protective outer plate 21a extend beyond the two first mounting beams 501a in the front-rear direction ab.

[0215] For example, the second protective outer plate 21b is sealed to the third protective outer plate 21c.

[0216] For example, the first mounting beam 501a is not provided with a protective outer plate 21 in the front-to-back direction ab, so as to expose the wire hole 5014 of the first mounting beam 501a for easy wiring.

[0217] Thus, by setting multiple protective outer plates 21 to construct the outer protective assembly 2, a large area of ​​coverage is formed for the battery device 100, the protective cover 11 and its surrounding area; and by reasonably arranging the positions of the first protective outer plate 21a, the second protective outer plate 21b and the third protective outer plate 21c, the outer protective assembly 2 can effectively protect the battery device 100 from different directions, improve the cleanliness of the mating parts of the battery device 100 and the battery mounting bracket 500, and improve the stability of battery swapping.

[0218] In some embodiments, such as Figure 3 and Figure 4 As shown, the two ends of the first protective outer plate 21a along the vehicle width direction cd are respectively overlapped and connected to the upper surfaces of the two second protective outer plates 21b.

[0219] For example, the two ends of the first protective outer plate 21a along the vehicle width direction cd are respectively overlapped on the upper surfaces of the two second protective outer plates 21b, and the connection is achieved by means such as bolts, clips, welding, etc.

[0220] The first protective outer panel 21a extends from both ends of the vehicle width direction cd to the top of the two second protective outer panels 21b and connects thereto. The overlapping arrangement between the first protective outer panel 21a and the second protective outer panel 21b makes the entire roof structure a continuous whole in the vehicle width direction cd, thereby improving the overall sealing and stability of the structure. The overlapping method between the first protective outer panel 21a and the second protective outer panel 21b not only enhances the structural strength of the outer protective component 2, but also helps to reduce the intrusion of foreign objects from the gaps between the protective outer panels 21.

[0221] A second aspect of this application provides a protective assembly 600 for protecting a battery device 100 mounted on a battery mounting bracket 500 in a vehicle 1000. The protective assembly 600 includes an inner protective component 1 and an outer protective component 2, both for connecting to the battery mounting bracket 500. The inner protective component 1 forms a protective cavity 111 with a downward-facing first opening. At least a portion of the battery device 100 extends into the protective cavity 111 through the first opening. The outer protective component 2 covers the side of the inner protective component 1 facing away from the protective cavity 111.

[0222] The protective assembly 600 includes an inner protective component 1 and an outer protective component 2. The inner protective component 1 has a protective cavity 111 to accommodate a portion of the battery device 100, reducing the direct accumulation of foreign objects on the upper surface of the battery device 100. Simultaneously, the outer protective component 2 covers the outer side of the inner protective component 1, further blocking impacts from the external environment and the intrusion of foreign objects. Since the outer protective component 2 is located on the outer layer, it acts as the first line of defense, absorbing most of the external impact force and blocking large foreign objects, thereby reducing the risk of damage to the inner protective component 1 and the battery device 100. This also helps reduce the accumulation of foreign objects in the battery device 100, improves the alignment accuracy of the battery device 100 and the battery mounting bracket 500, and enhances the stability of the battery swapping process. Furthermore, the protective assembly 600 reduces the frequency of cleaning the battery device 100, thereby reducing cleaning costs and improving battery swapping efficiency. In some battery swapping scenarios, the vehicle 1000 and battery device 100 can be cleaned outside the station. Specific cleaning methods include, but are not limited to, directly rinsing the vehicle 1000 and battery device 100 or replacing the protective assembly 600. The cleaning operation is convenient and further improves the battery swapping efficiency.

[0223] The following describes specific examples of some embodiments of this application with reference to the accompanying drawings.

[0224] As a specific example, a vehicle 1000 is provided, which includes a vehicle-end battery bracket (battery mounting bracket 500), a plastic cover (protective cover 11), an external frame (fixed frame 4), a sheet metal protective cover (outer protective component 2), a protective sleeve (protective shell 3), foam (elastic shielding strip 52), and a brush (brush 51). The plastic cover is connected to the mounting bracket and covers the mounting hole (mounting through hole 5013) on the vehicle-end battery bracket that does not cooperate with the quick-change lock (lock attachment component 30) of the battery pack (battery device 100), and also shields the top of the battery pack and part of the outer periphery of the battery pack. The sheet metal protective cover is fixed to the vehicle-end battery bracket by the external frame. The sheet metal protective cover is located at the outermost layer, which is the most vulnerable to the intrusion of foreign objects. It can block most large foreign objects, absorb impact force, reduce the probability of large objects or foreign objects falling and hitting the battery pack, and protect the safety of the inner components. This embodiment achieves double-layer protection. The plastic cover keeps the battery swapping interface clean, greatly reducing the amount of foreign matter such as mud, coal, stones, and branches left on the battery box. The sheet metal cover reduces the chance of most foreign objects falling into the mounting hole (installation through hole 5013) and damaging the quick-change lock (lock attachment assembly 30), as well as preventing interference caused by foreign objects remaining on the mounting hole interface. The left and right plastic covers (two second protective covers 11b located on both sides of the first protective cover 11a) are designed as a support structure to accommodate the arrangement of the quick-change lock, and are assembled from top to bottom onto the vehicle-end battery bracket and tightened with bolts. The middle plastic cover (first protective cover 11a) is a single piece, fixed to the connector mounting plate 504, eliminating the need for the vehicle-end electrical connector protective cover in the prior art. The connector mounting plate 504 and the middle plastic cover are directly integrated with the vehicle end by bolting. Foam is added to the edges of the left and right plastic covers (two second protective covers 11b located on both sides of the first protective cover 11a), and finally brushes 51 are installed on the outer beams on both sides to form a double-layer protection on the left and right sides. During car washing, this can block the high-pressure water guns on both sides from washing the battery sealing surface. By installing brushes 51, it can effectively resist external interference. A protective cover is installed at the mounting hole of the quick-change lock on the end of the vehicle battery bracket. The protective cover covers the outside of the part of the quick-change lock above the mounting hole, which can reduce the possibility of foreign objects falling into the quick-change lock. The plastic cover is directly assembled with the wear-resistant gasket (first gasket 503) through the same hole, simultaneously avoiding the battery swapping mounting area, and making it difficult for foreign objects to fall into the mounting hole. The reason why the middle crossbeam (first mounting beam 501a) is not covered with a sheet metal protective cover is that it passes through many wire harnesses and pipes, so no protection is needed. Also, this position is located at the innermost part of the vehicle end, so it is less affected by external interference. Furthermore, the sheet metal protective cover above can prevent most foreign objects from falling in, and foreign objects from the side rarely enter the battery swapping interface, so it is not installed.

[0225] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and all should be covered within the scope of the specification of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
