Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a vehicle. Background Technology

[0002] With the development of technology, battery devices have been widely used in rail transit, locomotives and other types of vehicles to drive vehicle operation.

[0003] During actual driving, vehicles often encounter various road conditions such as uphill climbs, curves, and bumps, causing their operating posture to change accordingly. Ensuring stable battery output under complex road conditions, thereby improving the overall operational reliability of the vehicle, is a pressing technical problem that needs to be solved in this field. Utility Model Content

[0004] In view of the above problems, this application provides a vehicle that can enhance the output stability of the battery device to improve the reliability of the vehicle.

[0005] This application provides a vehicle, including: a vehicle body including a mounting compartment; a battery device disposed within the mounting compartment; and an adjustment assembly including an elastic member and an adjustment member, wherein the elastic member is connected to the battery device and the wall of the mounting compartment, and the adjustment member is disposed within the battery device. The adjustment member is configured to move to cause the elastic member to deform in the direction of gravity, thereby adjusting the tilt angle of the battery device relative to the horizontal plane.

[0006] In this embodiment of the application, the vehicle includes a vehicle body, a battery device, and an adjustment component. The vehicle body has a mounting compartment, and the battery device is disposed within the mounting compartment. The adjustment component includes an elastic member and an adjusting member. The battery device is connected to the wall of the mounting compartment via the elastic member, and the adjusting member is disposed within the battery device. When the vehicle tilts, causing the battery device to tilt accordingly, the adjusting member moves to deform the elastic member, thereby actively adjusting the tilt angle of the battery device relative to the horizontal plane. This improves the problems caused by poor electrode wetting, increased internal resistance of individual battery cells, and easy undervoltage of the battery device, which can lead to vehicle breakdowns due to battery device tilting. This helps to enhance the output stability of the battery device and improve the reliability of the vehicle.

[0007] In some embodiments, the vehicle body further includes an angle sensor for acquiring angle information between the vehicle body and the horizontal plane, and the adjustment component is configured to adjust the position of the adjustment member in the direction of gravity based on the angle information.

[0008] In the embodiment of this application, the vehicle further includes an angle sensor. The angle sensor is used to acquire the angle information between the vehicle body and the horizontal plane. The adjustment component adjusts the position of the adjustment member in the direction of gravity based on this angle information. When the vehicle body tilts, the adjustment member can adjust its position in the direction of gravity according to the actual tilt angle of the vehicle body, thereby changing the compression of the elastic member. This helps to match the attitude adjustment of the battery device with the tilt degree of the vehicle body, thereby achieving precise control of the tilt angle of the battery device. This helps to further ensure the output stability of the battery device under various tilt conditions and improve the reliability of the vehicle.

[0009] In some embodiments, the battery device includes a control unit electrically connected to an angle sensor, the control unit being configured to adjust the output current of the battery device based on the included angle information.

[0010] In the embodiment of this application, the battery device includes a control unit, which can adjust the output current of the battery device based on the angle information obtained by the angle sensor. When the vehicle body tilts, the control unit can adaptively reduce the output current to avoid abnormal voltage drop caused by increased internal resistance due to battery device tilt, thereby improving vehicle reliability.

[0011] In some embodiments, the adjustment assembly includes at least two adjustment members, which are respectively disposed on two halves of the battery device in the width direction of the vehicle body and are fixedly connected to the battery device.

[0012] In the embodiment of this application, two adjusting members are respectively disposed on the two halves of the battery device in the width direction of the vehicle body, and the position of each adjusting member in the direction of gravity can be adjusted independently. When the vehicle body tilts, the positions of the two adjusting members in the direction of gravity can be adjusted respectively to apply forces in different directions to both sides of the battery device, thereby driving the battery device to rotate in the opposite direction to the tilt direction of the vehicle body. This achieves precise and rapid adjustment of the tilt angle of the battery device, which helps to improve the response speed of the adjusting components and further ensures the output stability of the battery device.

[0013] In some embodiments, the adjusting member is movable along the width direction of the vehicle body.

[0014] In the embodiment of this application, the adjusting member is movably disposed along the width direction of the vehicle body. When the vehicle body tilts, the adjusting member can be displaced in the width direction of the vehicle body, thereby causing the battery device to bear different elastic forces on both sides, which in turn drives the battery device to rotate around its rotation axis to adjust the tilt angle of the battery device relative to the horizontal plane. The attitude adjustment of the battery device can be achieved by the overall translation of the adjusting member, which helps to simplify the structure, reduce the number of parts, and thus reduce the difficulty of vehicle manufacturing and processing.

[0015] In some embodiments, the vehicle body further includes an angle sensor for acquiring angle information between the vehicle body and the horizontal plane. The adjustment assembly further includes a drive member connected to the adjustment member to drive the adjustment member to move in the width direction of the vehicle body. The angle sensor is connected to the drive member, and the drive member is configured to adjust the position of the adjustment member in the width direction of the vehicle body based on the angle information.

[0016] In the embodiment of this application, the adjustment component further includes a driving component connected to the adjustment member. An angle sensor acquires the angle information between the vehicle body and the horizontal plane and transmits it to the driving component. The driving component drives the adjustment member to move in the width direction of the vehicle body based on this angle information. The driving component can adjust the position of the adjustment member in the width direction according to the vehicle's tilt angle. Through the counterweight effect of the adjustment member itself, it actively adjusts the vehicle's center of gravity position to reduce the vehicle's center of gravity offset, which helps improve the vehicle's stability under tilt conditions and further enhances the vehicle's reliability.

[0017] In some embodiments, the vehicle further includes a pressure sensor, an elastic element disposed on one side of the battery device in the direction of gravity, the pressure sensor being disposed between the battery device and the elastic element, the pressure sensor being used to acquire pressure information, the pressure sensor being connected to a drive element, the drive element being configured to adjust the position of the adjustment element in the width direction of the vehicle body based on the included angle information and the pressure information.

[0018] In this embodiment of the application, the vehicle also includes a pressure sensor for acquiring battery device pressure information. The drive component can adjust the position of the adjustment component based on the included angle information and pressure information. In actual use, the battery device will experience weight changes during use. By adding a pressure sensor, the actual pressure value of the battery device can be obtained, and combined with the vehicle body tilt angle, the center of gravity offset of the battery device can be calculated in real time. Thus, the adjustment component is precisely driven to move according to the actual center of gravity offset. Therefore, this solution can adapt to the battery device at different stages of use, achieve precise center of gravity adjustment, and further improve the stability and reliability of the vehicle.

[0019] In some embodiments, the drive element includes a lead screw, and an adjusting element is threadedly connected to the drive element.

[0020] In the embodiment of this application, the drive component converts rotational motion into linear motion of the adjusting component through a lead screw thread engagement, achieving precise displacement of the adjusting component in the vehicle width direction. This transmission method offers smooth transmission, high positioning accuracy, and excellent self-locking performance, effectively preventing unexpected displacement of the adjusting component due to vibration or impact during vehicle operation, ensuring positional stability after attitude adjustment, and improving the operational reliability of the adjusting assembly.

[0021] In some embodiments, the adjustment assembly further includes a mating member, which is connected to the mounting chamber and spaced apart along the direction of gravity. One of the mating member and the adjustment member is an electromagnet, and the other of the mating member and the adjustment member is a magnetic element.

[0022] In the embodiment of this application, the adjustment component further includes a mating component. The mating component is connected to the mounting chamber and spaced apart along the direction of gravity. One of the mating component and the adjustment component is an electromagnet, and the other is a magnetic component. Through the magnetic interaction between the electromagnet and the magnetic component, a driving force is generated when the electromagnet is energized, causing the adjustment component to displace relative to the mating component in the direction of gravity, thereby driving the elastic component to deform. No intermediate transmission component is required, the required installation space is small, and the assembly difficulty of the adjustment component is reduced.

[0023] In some embodiments, the vehicle body includes two mounting compartments located on both sides of the vehicle body in the width direction, and the vehicle includes two battery devices located in the two mounting compartments.

[0024] In the embodiment of this application, the vehicle body includes two mounting compartments. By independently setting battery devices on both sides of the vehicle body width direction, the weight of the battery devices is distributed in the vehicle body width direction, which helps to reduce the center of gravity height of the entire vehicle, reduce the lateral tilt moment of the vehicle under tilt conditions, and improve the stability of the vehicle.

[0035] In this embodiment of the application, the battery cell can be a secondary battery cell, which refers to a battery cell that can be used again after being discharged by recharging to activate the active materials.

[0036] The battery cell can be a lithium-ion battery cell, a sodium-ion battery cell, a sodium-lithium-ion battery cell, a lithium metal battery cell, a sodium metal battery cell, a lithium-sulfur battery cell, a magnesium-ion battery cell, a nickel-metal hydride battery cell, a nickel-cadmium battery cell, a lead-acid battery cell, etc., but the embodiments of this application are not limited to this.

[0037] A typical battery cell includes an electrode assembly, a housing, and electrode terminals. The electrode assembly is housed within the housing, and the electrode terminals are located within the housing. The housing encapsulates the electrode assembly and electrolyte components. The electrode assembly includes tabs, which are electrically connected to the electrode terminals via adapters or directly to the electrode terminals. The electrode terminals are used to electrically connect the electrode assembly to external circuitry within the battery cell to enable charging or discharging of the battery cell.

[0038] The electrode assembly includes a positive electrode, a negative electrode, and a separator. During the charging and discharging process of a single battery cell, active ions (such as lithium ions) repeatedly insert and extract between the positive and negative electrodes. The separator, positioned between the positive and negative electrodes, prevents short circuits while allowing active ions to pass through.

[0039] In some embodiments, the positive electrode may be a positive electrode sheet, which may include a positive electrode current collector and a positive electrode active material disposed on at least one surface of the positive electrode current collector.

[0040] In some embodiments, the negative electrode may be a negative electrode sheet, which may include a negative electrode current collector and a negative electrode active material disposed on at least one surface of the negative electrode current collector.

[0041] In some implementations, the separator is positioned between the positive and negative electrodes.

[0042] In some embodiments, the separator is a separator membrane. This application does not impose any particular limitation on the type of separator membrane; any known porous separator membrane with good chemical and mechanical stability can be selected.

[0043] In some embodiments, the separator is a solid electrolyte. The solid electrolyte is disposed between the positive and negative electrodes, serving both to transport ions and to isolate the positive and negative electrodes.

[0044] In some embodiments, the electrode assembly is a wound structure. The positive electrode and the negative electrode are wound into a wound structure.

[0045] In some embodiments, the electrode assembly has a stacked structure.

[0046] The battery device mentioned in the embodiments of this application may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells, which are connected in series, parallel, or mixed connections via a busbar.

[0047] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells.

[0048] A battery device typically includes a housing for encapsulating one or more individual battery cells. The housing prevents liquids or other foreign matter from affecting the charging or discharging of the individual battery cells.

[0049] As an example, a battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells into an independent module. As an example, a battery module can be formed by bundling multiple battery cells together with cable ties. The battery cell assembly can be housed within a housing by fixing the battery module within the housing. As an example, the housing can include a top cover, a frame, and a bottom plate. The top cover and bottom plate are respectively connected to the frame, creating a closed space inside the housing to house the battery cell assembly.

[0050] In some embodiments, the housing may be part of the vehicle's chassis structure. For example, a portion of the housing may be at least a part of the vehicle's floor, or a portion of the housing may be at least a part of the vehicle's crossbeams and longitudinal beams.

[0051] In some embodiments, the battery device may be an energy storage device. Energy storage devices include energy storage containers, energy storage cabinets, etc.

[0052] With the development of technology, battery devices have been widely used in rail transit, locomotives, and other types of vehicles to drive their operation. During actual driving, vehicles often encounter different road conditions such as climbing hills, curves, and bumps, and their operating behavior changes accordingly.

[0053] In related technologies, when a locomotive or rail vehicle is tilted, such as when turning, the tilt of the vehicle will cause the battery device to tilt. When the battery device tilts, the electrolyte level of the battery cells inside the battery device tilts, which will cause part of the electrode to be exposed in the electrolyte, resulting in an increase in the internal resistance of the battery cells. The battery device is prone to causing the vehicle to break down due to undervoltage.

[0054] In view of this, this application provides a vehicle including a vehicle body, a battery device, and an adjustment component. The vehicle body has a mounting compartment, and the battery device is disposed within the mounting compartment. The adjustment component includes an elastic member and an adjusting member. The battery device is connected to the wall of the mounting compartment via the elastic member, and the adjusting member is disposed within the battery device. When the vehicle tilts, causing the battery device to tilt accordingly, the adjusting member moves to deform the elastic member, thereby actively adjusting the tilt angle of the battery device relative to the horizontal plane. This improves the problems of poor electrode wetting, increased internal resistance of individual battery cells, and easy undervoltage of the battery device caused by the tilt of the battery device, which can lead to vehicle breakdown. This helps to enhance the output stability of the battery device and improve the reliability of the vehicle.

[0055] The battery device disclosed in this application can be used in electrical equipment that uses a battery device as a power source.

[0056] For ease of explanation, the following embodiments use a vehicle as an example of electrical equipment.

[0057] Figure 1 This is a schematic diagram of the vehicle structure provided in some embodiments of this application. (Refer to...) Figure 1Vehicle 1 can be a new energy vehicle, such as a pure electric vehicle, a hybrid electric vehicle, or a range-extended electric vehicle. A battery device 2 is installed inside vehicle 1, and the battery device 2 can be located at the bottom, front, or rear of vehicle 1. The battery device 2 can be used to power vehicle 1, serving as its drive power source. Vehicle 1 may also include a controller 3 and a motor 4, with the controller 3 controlling the battery device 2 to supply power to the motor 4.

[0058] Figure 2 This is an exploded structural diagram of a battery device provided in some embodiments of this application. (Refer to...) Figure 2 The battery device 2 includes a housing 5 and battery cells 6, with the battery cells 6 housed within the housing 5. The housing 5 provides space for the battery cells 6 and can have various structures. In some embodiments, the housing 5 may include a first housing portion 5a and a second housing portion 5b, which overlap each other, collectively defining a space for accommodating the battery cells 6. The second housing portion 5b may be a hollow structure with one open end, while the first housing portion 5a may be a plate-like structure, covering the open side of the second housing portion 5b so that the first housing portion 5a and the second housing portion 5b together define the accommodating space. Alternatively, both the first housing portion 5a and the second housing portion 5b may be hollow structures with one open side, with the open side of the first housing portion 5a covering the open side of the second housing portion 5b. Of course, the box 5 formed by the first box part 5a and the second box part 5b can be of various shapes, such as a cylinder, a cuboid, etc.

[0059] To improve the sealing performance after the first housing part 5a and the second housing part 5b are connected, sealing components, such as sealant or sealing rings, can also be provided between the first housing part 5a and the second housing part 5b.

[0060] Assuming that the first box section 5a covers the top of the second box section 5b, the first box section 5a can also be called the upper box cover, and the second box section 5b can also be called the lower box.

[0061] In the battery device 2, there can be multiple battery cells 6, which can be connected in series, parallel, or in a mixed manner. A mixed connection means that multiple battery cells 6 are connected in both series and parallel configurations. Multiple battery cells 6 can be directly connected in series, parallel, or in a mixed manner, and then the entire assembly of the multiple battery cells 6 is housed within the housing 5. Alternatively, the battery device 2 can also consist of multiple battery cells 6 first connected in series, parallel, or in a mixed manner to form battery modules, and then these battery modules are connected in series, parallel, or in a mixed manner to form a whole, which is also housed within the housing 5. The battery device 2 may also include other structures; for example, it may include a busbar component for electrical connection between the multiple battery cells 6.

[0062] For example, the battery cell 6 may be the smallest unit that makes up the battery device 2.

[0063] Figure 3 These are exploded views of a single battery cell provided in some embodiments of this application. (Refer to...) Figure 3 The battery cell 6 includes an electrode assembly 10 and a housing 20, with the electrode assembly 10 disposed inside the housing 20.

[0064] Electrode assembly 10 is the component in the battery cell 6 where electrochemical reactions occur. The casing may contain one or more electrode assemblies 10. Electrode assembly 10 is mainly formed by winding or stacking electrode sheets, which are divided into positive and negative electrode sheets, and a separator is usually provided between the positive and negative electrode sheets. The portions of the positive and negative electrode sheets containing active material constitute the electrode body 11, while the portions of the positive and negative electrode sheets without active material each constitute a tab 12. The positive and negative tabs can be located together at one end of the electrode body 11 or separately at both ends of the electrode body 11. During the charging and discharging process of the battery cell 6, the positive and negative active materials react with the electrolyte, and the tabs 12 connect to the electrode terminals to form a current loop.

[0065] The electrode assembly 10 can be a wound structure, a stacked structure, or a hybrid structure of wound and stacked.

[0066] In some embodiments, the electrode assembly 10 is a wound structure. The positive electrode and the negative electrode are wound into a wound structure.

[0067] In some embodiments, the electrode assembly 10 has a stacked structure. As an example, multiple positive and negative electrodes can be provided, with multiple positive and multiple negative electrodes stacked alternately. Multiple spacers can be provided and respectively provided between any adjacent positive or negative electrodes. Alternatively, the spacers can be provided continuously and provided between any adjacent positive or negative electrodes by folding.

[0068] The outer casing 20 is used to encapsulate the electrode assembly 10 and electrolyte components. The outer casing 20 can be made of steel, aluminum, plastic (such as polypropylene), composite metal (such as copper-aluminum composite), or aluminum-plastic film, etc.

[0069] In some embodiments, the housing 20 is a hollow structure, with an internal space for accommodating the electrode assembly 10 and the electrolyte. The shape of the housing 20 can be determined according to the specific shape of the electrode assembly 10. For example, if the electrode assembly 10 has a cuboid structure, a cuboid housing can be selected.

[0070] The outer casing 20 can be made of various materials, such as metal or plastic. Optionally, the outer casing 20 can be made of copper, iron, aluminum, steel, aluminum alloy, etc. For example, the outer casing 20 can be a steel casing, aluminum casing, plastic casing (such as polypropylene), composite metal casing (such as copper-aluminum composite casing), or aluminum-plastic film, etc.

[0071] As an example, housing 20 includes a housing and an end cap, the housing having a housing opening and the end cap for closing the housing opening.

[0072] The housing is a component used to fit the end cap to form the internal cavity of the battery cell 6. The formed internal cavity can be used to accommodate the electrode assembly 10, the electrolyte, and other components.

[0073] The housing and end cap can be separate components. For example, a housing opening can be provided on the housing, and the end cap can be used to close the housing opening to form an internal cavity of the battery cell 6.

[0074] The shape of the end cap can be adapted to the shape of the housing to fit the housing. The material of the end cap can be the same as or different from that of the housing.

[0075] The end caps can be attached to the housing by welding, bonding, snap-fitting or other means.

[0076] The housing may have an opening at one end or at both ends. For example, the housing may have an opening on one side, with one end cap covering the opening. As another example, the housing may also have openings on both sides, with two end caps covering the two openings respectively.

[0077] Please see Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , Figure 4 This is a top view structural diagram of a vehicle provided in some embodiments of this application; Figure 5 This is a front view structural schematic diagram of a vehicle provided in some embodiments of this application; Figure 6 This is a top view structural schematic diagram of a vehicle provided in other embodiments of this application; Figure 7 This is a front view structural schematic diagram of a vehicle provided in other embodiments of this application; Figure 8 This is a front view structural schematic diagram of a vehicle provided in some embodiments of this application.

[0078] like Figures 4 to 8As shown, this application provides a vehicle 1, which includes a vehicle body 30, a battery device 2, and an adjustment assembly 40. The vehicle body 30 includes a mounting compartment 31; the battery device 2 is disposed in the mounting compartment 31; the adjustment assembly 40 includes an elastic member 41 and an adjustment member 42. The elastic member 41 is connected to the battery device 2 and the compartment wall of the mounting compartment 31, and the adjustment member 42 is disposed on the battery device 2. The adjustment member 42 is configured to move and cause the elastic member 41 to deform in the direction of gravity to adjust the tilt angle of the battery device 2 relative to the horizontal plane.

[0079] Optionally, vehicle 1 can be a rail vehicle or a locomotive, and the locomotive can be a two-wheeled vehicle such as a motorcycle. When turning, rail vehicles or locomotives must tilt towards the inside of the curve, using the inward component of gravity to provide centripetal force.

[0080] Optionally, the mounting compartment 31 includes a compartment wall and an accommodating space defined by the compartment wall. The compartment wall can be an independent structure connected to the frame or the compartment wall can reuse the frame. For example, the number of mounting compartments 31 can be 1, 2, 3, 4, etc.

[0081] Optionally, the battery device 2 is disposed within the mounting compartment 31, and the battery device 2 is used to drive the vehicle 1. Exemplarily, the battery device 2 is detachably connected to the mounting compartment 31.

[0082] Optionally, the battery device 2 includes a housing 5 and a plurality of battery cells 6 located within the housing 5. Each battery cell 6 contains an electrolyte and electrode plates. When the vehicle 1 is traveling straight, the electrode plates are submerged in the electrolyte. When the vehicle 1 turns, the electrolyte level tilts, and a portion of the electrode plates is exposed outside the electrolyte. Exemplarily, the battery cells 6 can be placed upright, upside down, or flat within the battery device 2.

[0083] Optionally, the direction of the battery device 2 toward the elastic member 41 is the direction of gravity, or in other words, the elastic member 41 is located below the battery device 2. For example, when the vehicle 1 turns right and the vehicle body 30 tilts to the right relative to the horizontal plane, the elastic member 41 located on the left half of the battery device 2 is compressed; when the vehicle 1 turns left and the vehicle body 30 tilts to the left relative to the horizontal plane, the elastic member 41 located on the right half of the battery device 2 is compressed. And / or, the direction in which the elastic member 41 points toward the battery device 2 is the direction of gravity, or in other words, the elastic member 41 is located above the battery device 2. For example, when the vehicle 1 turns right and the vehicle body 30 tilts to the right relative to the horizontal plane, the elastic member 41 located on the left half of the battery device 2 is stretched; when the vehicle 1 turns left and the vehicle body 30 tilts to the left relative to the horizontal plane, the elastic member 41 located on the right half of the battery device 2 is stretched.

[0084] The direction of gravity is shown in the Z direction in the attached figure.

[0085] For example, the elastic element 41 can be a spring, an elastic block, an elastic strip, etc. For example, one end of the elastic element 41 is connected to the battery device 2, and the other end extends in a straight line along the direction of gravity or away from the direction of gravity, or one end of the elastic element 41 is connected to the battery device 2, and the other end extends at an angle.

[0086] Optionally, the battery device 2 includes a housing 5 and a plurality of battery cells 6 located inside the housing 5. An adjusting member 42 is connected to the housing 5 and is located on the outside of the housing 5. The adjusting member 42 does not occupy the internal space of the housing 5 and reduces the risk of interference between the adjusting member 42 and the battery cells 6. Alternatively, the adjusting member 42 is located on the inside of the housing 5. The adjusting member 42 utilizes the internal space of the housing 5 and does not occupy additional space in the installation compartment 31, which helps to make the overall vehicle layout more compact.

[0087] Optionally, along the length of the vehicle body 30, i.e., the direction of the front and rear of the vehicle, the adjusting member 42 is disposed in the middle of the battery device 2, and the adjusting member 42 is disposed at both ends of the battery device 2, so that the adjusting member 42 drives the battery device 2 to tilt or rotate stably. For example, the adjusting member 42 drives the battery device 2 to rotate about an axis extending along the length of the vehicle body 30.

[0088] In the attached figure, Y indicates the length direction of the vehicle body 30.

[0089] Optionally, the adjusting member 42 is movable in the direction of gravity. For example, when vehicle 1 turns right and the vehicle body 30 tilts to the right relative to the horizontal plane, the battery device 2 tilts relative to the horizontal plane. In the direction perpendicular to the horizontal plane, the direction from the left end of the battery device 2 to the right end is the direction of gravity. Using the adjusting component 40 of this embodiment, the adjusting member 42 is located on the left half of the battery device 2 and moves along the direction of gravity to deform the elastic member 41, thereby adjusting the tilt of the battery device 2 relative to the horizontal plane. The left end of the battery device 2 moves relative to the right end along the direction of gravity so that the left and right ends of the battery device 2 are close to horizontal, that is, so that the electrolyte level is close to horizontal. The same applies when vehicle 1 turns left, and will not be described again here.

[0090] The virtual horizontal plane is indicated by S in the attached diagram.

[0091] Optionally, the adjustment component 40 includes a magnetic structure disposed on the wall of the installation chamber 31. The magnetic structure is magnetically connected to the adjustment member 42, and the adjustment member 42 is moved in the direction of gravity by the magnetic structure. The magnetic structure does not require an intermediate transmission component and requires less installation space. Alternatively, the adjustment component 40 includes a telescopic structure. One end of the telescopic structure is connected to the wall of the installation chamber 31, and the other end is connected to the adjustment member 42. The adjustment member 42 is moved in the direction of gravity by the telescopic structure. The telescopic structure has high reliability. Alternatively, the adjustment component 40 includes a transmission belt structure. One end of the transmission belt structure is connected to the wall of the installation chamber 31, and the other end is connected to the adjustment member 42. The adjustment member 42 is moved in the direction of gravity by the transmission belt structure.

[0092] Optionally, the adjusting member 42 is fixed to at least one half of the battery device 2 in the width direction of the vehicle body 30, or the adjusting member 42 is movable relative to the battery device 2 in the width direction of the vehicle body 30, and the adjusting member 42 can be moved to one half of the battery device 2 in the width direction of the vehicle body 30 and then moved along the direction of gravity.

[0093] The length direction of the vehicle body 30 is indicated by X in the attached figure.

[0094] In this embodiment of the application, vehicle 1 includes a vehicle body 30, a battery device 2, and an adjustment assembly 40. The vehicle body 30 has a mounting compartment 31, and the battery device 2 is disposed within the mounting compartment 31. The adjustment assembly 40 includes an elastic member 41 and an adjustment member 42. The battery device 2 is connected to the wall of the mounting compartment 31 via the elastic member 41, and the adjustment member 42 is disposed on the battery device 2. When vehicle 1 tilts, causing battery device 2 to tilt accordingly, the adjustment member 42 moves to deform the elastic member 41, thereby actively adjusting the tilt angle of battery device 2 relative to the horizontal plane. This improves the problems caused by poor electrode wetting, increased internal resistance of battery cells 6, and easy undervoltage of battery device 2, which can lead to vehicle 1 breakdowns. This helps to enhance the output stability of battery device 2 and improve the reliability of vehicle 1.

[0095] In some embodiments, such as Figure 4 and Figure 6 As shown, the vehicle body 30 also includes an angle sensor 50, which is used to obtain the angle information between the vehicle body 30 and the horizontal plane. The adjustment component 40 is configured to adjust the position of the adjustment component 42 in the direction of gravity based on the angle information.

[0096] Optionally, the angle sensor 50 is disposed on the vehicle body 30 or the mounting compartment 31, and the angle sensor 50 acquires the angle information of the vehicle body 30 and the horizontal plane when the vehicle body 30 is tilted.

[0097] The adjustment assembly 40 adjusts the displacement of the adjustment member 42 in the direction of gravity based on the included angle information, or the adjustment assembly 40 adjusts the position of the adjustment member 42 in the direction of gravity based on the included angle information. For example, the larger the tilt angle of the vehicle body 30, the larger the included angle information obtained by the angle sensor 50, and the larger the displacement of the adjustment member 42 in the direction of gravity, so as to reliably level the battery device 2. For example, the adjustment assembly 40 also includes a displacement sensor for acquiring the displacement information of the adjustment member 42 in the direction of gravity; or the adjustment assembly 40 also includes a position sensor for acquiring the position information of the adjustment member 42 in the direction of gravity.

[0098] In these embodiments, vehicle 1 also includes an angle sensor 50, which is used to acquire the angle information between the vehicle body 30 and the horizontal plane. The adjustment component 40 adjusts the position of the adjustment member 42 in the direction of gravity based on the angle information. When the vehicle body 30 tilts, the adjustment member 42 can adjust its position in the direction of gravity according to the actual tilt angle of the vehicle body 30, thereby changing the compression of the elastic member 41. This helps to match the attitude adjustment of the battery device 2 with the tilt degree of the vehicle body 30, thereby achieving precise control of the tilt angle of the battery device 2. This helps to further ensure the output stability of the battery device 2 under various tilt conditions and improve the reliability of vehicle 1.

[0099] In some embodiments, such as Figure 4 and Figure 6 As shown, the battery device 2 includes a control unit 201, which is electrically connected to an angle sensor 50. The control unit 201 is configured to adjust the output current of the battery device 2 based on the included angle information.

[0100] Optionally, the control unit 201 includes a battery management system.

[0101] Optionally, when the vehicle body 30 tilts and the internal resistance of the battery cell 6 increases, the control unit 201 reduces the output current and output power of the battery device 2 to improve the problem of undervoltage breakdown when the vehicle 1 is tilted; when the vehicle body 30 returns to a horizontal position, the control unit 201 can restore the output current in time to ensure power supply.

[0102] Optionally, when the included angle information is within a first threshold range, the control unit 201 adjusts the output current of the battery device 2 based on the included angle information; when the included angle information is within a second threshold range, the adjustment component 40 adjusts the position of the adjustment member 42 in the direction of gravity based on the included angle information, wherein the first threshold range is smaller than the second threshold range. The coordinated mechanical adjustment of the control unit 201 and the adjustment component 40 further enhances the output stability of the battery device 2 under different tilt conditions.

[0103] Optionally, when the included angle information is within the third threshold range, the adjustment member 42 does not move in the direction of gravity, and the control component does not adjust the output current of the battery device 2 based on the included angle information. The third threshold range is smaller than the first threshold range, so as to improve the problem of insufficient output power of the battery device 2 when the vehicle 1 tilts or vibrates slightly.

[0104] The first threshold range, the second threshold range, and the third threshold range can be designed according to actual conditions. For example, the third threshold range is 0° to 5°, the first threshold range is 5° to 20°, and the second threshold range is 20° to 60°.

[0105] Optionally, if the included angle information exceeds the second threshold range, the adjustment component 40 will not operate and will output an alarm message.

[0106] In these embodiments, the battery device 2 includes a control unit 201, which adjusts the output current of the battery device 2 based on the angle information obtained by the angle sensor 50. When the vehicle body 30 tilts at a large angle, the control unit 201 can adaptively reduce the output current to avoid abnormal voltage drops caused by increased internal resistance due to the tilt of the battery device 2; when the vehicle body 30 returns to a horizontal position, the control unit 201 can promptly restore the output current to ensure power supply. The coordinated mechanical adjustment of the control unit 201 and the adjustment component 40 further enhances the output stability of the battery device 2 under different tilt conditions from an electrical perspective, improving the reliability of the vehicle 1.

[0107] In some embodiments, such as Figure 4 and Figure 5 As shown, the adjustment assembly 40 includes at least two adjustment members 42, which are respectively disposed on two halves of the battery device 2 in the width direction of the vehicle body 30 and are fixedly connected to the battery device 2.

[0108] The two halves of the battery device 2 are located on both sides of the centerline extending along the length of the vehicle body 30.

[0109] Optionally, the two halves are arranged symmetrically along the centerline of the battery device 2 extending in the length direction of the vehicle body 30, so that the battery device 2 is subjected to force balance on both sides. For example, two adjusting members 42 are respectively disposed at both ends of the battery device 2 in the width direction of the vehicle body 30 to increase the lever arm and improve the adjustment speed.

[0110] Optionally, during the tilting of the vehicle body 30, the adjustment component 42 located in one half of the battery device 2 actively moves in the direction of gravity, while the adjustment component 42 located in the other half of the battery device 2 does not move, so as to reduce the control difficulty of the adjustment component 40.

[0111] Optionally, during the tilting of the vehicle body 30, the adjusting members 42 located in the two halves of the battery device 2 move in opposite directions to increase the adjustment speed of the adjusting assembly 40.

[0112] In these embodiments, two adjusting members 42 are respectively disposed on the two halves of the battery device 2 in the width direction of the vehicle body 30, and the position of each adjusting member 42 in the direction of gravity can be adjusted independently. When the vehicle body 30 tilts, the positions of the two adjusting members 42 in the direction of gravity can be adjusted respectively to apply forces in different directions to both sides of the battery device 2, thereby driving the battery device 2 to rotate in the opposite direction to the tilt direction of the vehicle body 30. This achieves precise and rapid adjustment of the tilt angle of the battery device 2, which helps to improve the response speed of the adjusting component 40 and further ensures the output stability of the battery device 2.

[0113] In some embodiments, such as Figures 6 to 8 As shown, the adjusting member 42 is movable along the width direction of the vehicle body 30.

[0114] Optionally, when the battery device 2 is horizontal, or when the included angle information is within the third threshold range, the adjusting member 42 is centered along the width direction of the vehicle body 30 to balance the center of gravity of the vehicle 1.

[0115] For example, when the vehicle 1 turns right, the adjusting member 42 moves from the center position to the left half of the battery device 2; when the vehicle 1 turns left, the adjusting member 42 moves from the center position to the right half of the battery device 2.

[0116] For example, the adjusting member 42 can reciprocate from the central position of the battery device 2 to the end of the battery device 2 in the width direction of the vehicle body 30.

[0117] In these embodiments, the adjusting member 42 is movably disposed along the width direction of the vehicle body 30. When the vehicle body 30 tilts, the adjusting member 42 can be displaced in the width direction of the vehicle body 30, thereby causing the battery device 2 to bear different elastic forces on both sides, which in turn drives the battery device 2 to rotate around its rotation axis to adjust the tilt angle of the battery device 2 relative to the horizontal plane. The attitude adjustment of the battery device 2 can be achieved by the overall translation of the adjusting member 42, which helps to simplify the structure, reduce the number of parts, and thus reduce the manufacturing and processing difficulty of the vehicle 1.

[0118] In some embodiments, such as Figures 6 to 8 As shown, the vehicle body 30 also includes an angle sensor 50, which is used to obtain the angle information between the vehicle body 30 and the horizontal plane. The adjustment assembly 40 also includes a drive member 43, which is connected to the adjustment member 42 to drive the adjustment member 42 to move in the width direction of the vehicle body 30. The angle sensor 50 is connected to the drive member 43, and the drive member 43 is configured to adjust the position of the adjustment member 42 in the width direction of the vehicle body 30 based on the angle information.

[0119] When vehicle 1 turns right and tilts to the right, the vehicle's center of gravity shifts to the right. The drive adjustment component 42 moves to the left, generating a reverse adjustment torque, which shifts the vehicle's center of gravity back towards the centerline, thereby reducing the center of gravity shift and improving the stability of vehicle 1 under tilting conditions. The same principle applies when vehicle 1 turns left.

[0120] For example, Δx = (M × h × sinθ) / m, where Δx is the distance (m) from the adjusting member 42 to the midpoint of the battery device 2 in the width direction of the vehicle body 30, or the distance of the adjusting member 42 from the center position; M is the total mass of the vehicle 1 (kg); h is the height of the center of gravity of the vehicle 1 (m); θ is the vehicle body tilt angle (°), which is the included angle information obtained by the angle sensor 50; and m is the mass of the counterweight (kg). That is, the larger the tilt angle of the vehicle 1, the greater the offset of the center of gravity of the vehicle 1, and the greater the moving distance of the adjusting member 42; the smaller the tilt angle of the vehicle 1, the smaller the offset of the center of gravity of the vehicle 1, and the smaller the moving distance of the adjusting member 42.

[0121] Optionally, the drive component 43 can be a motor, a pneumatic mechanism, or a hydraulic mechanism, etc.

[0122] In these embodiments, the adjustment assembly 40 is further provided with a drive component 43 connected to the adjustment component 42. The angle sensor 50 acquires the angle information between the vehicle body 30 and the horizontal plane and transmits it to the drive component 43. The drive component 43 drives the adjustment component 42 to move in the width direction of the vehicle body 30 based on the angle information. The drive component 43 can adjust the position of the adjustment component 42 in the width direction according to the tilt angle of the vehicle 1. By actively adjusting the center of gravity position of the vehicle 1 through the counterweight effect of the adjustment component 42, the center of gravity offset of the vehicle 1 is reduced, which helps to improve the stability of the vehicle 1 under tilt conditions and further improves the reliability of the vehicle 1.

[0123] In some embodiments, such as Figure 6 and Figure 8 As shown, vehicle 1 also includes a pressure sensor 60. Elastic member 41 is disposed on one side of battery device 2 in the direction of gravity. Pressure sensor 60 is disposed between battery device 2 and elastic member 41. Pressure sensor 60 is used to acquire pressure information. Pressure sensor 60 is connected to drive member 43. Drive member 43 is configured to adjust the position of adjustment member 42 in the width direction of vehicle body 30 based on angle information and pressure information.

[0124] The elastic element 41 is located on the side of the battery device 2 in the direction of gravity, meaning that the direction of gravity is the direction from the battery device 2 to the elastic element 41.

[0125] For example, the weight of the battery device 2 may change during use due to wear of mechanical parts, evaporation of electrolyte, evaporation of cooling medium, etc. The pressure sensor 60 is used to obtain the actual weight information of the battery device 2.

[0126] Optionally, M B =F / g, Δx=(M) B ×h B ×sinθ) / m, where M B The actual weight of battery device 2 (kg); F is the reading of pressure sensor 60 (N); Δx is the distance (m) from the adjustment member 42 to the midpoint of battery device 2 in the width direction of vehicle body 30, or the distance of adjustment member 42 from the center position; h B θ is the height (m) from the center of gravity of battery device 2 to its axis of rotation; θ is the vehicle body tilt angle (°). When the vehicle body tilt angle is the same, the greater the weight of battery device 2, the greater the moving distance of the adjusting component 42; the smaller the weight of battery device 2, the smaller the moving distance of the adjusting component 42.

[0127] In these embodiments, vehicle 1 also includes a pressure sensor 60 for acquiring pressure information of battery device 2, and drive component 43 can adjust the position of adjustment component 42 based on angle information and pressure information. In actual use, the weight of battery device 2 will change during use. By adding pressure sensor 60, the actual pressure value of battery device 2 can be acquired, and combined with the tilt angle of vehicle body 30, the center of gravity offset of battery device 2 can be calculated in real time. Thus, the adjustment component 42 is precisely driven to move according to the actual center of gravity offset. Therefore, this solution can adapt to battery device 2 at different stages of use, achieve precise center of gravity adjustment, and further improve the stability and reliability of vehicle 1.

[0128] In some embodiments, such as Figures 6 to 8 As shown, the drive component 43 includes a lead screw, and the adjusting component 42 is threadedly connected to the drive component 43.

[0129] For example, the drive unit 43 also includes a motor that drives the lead screw to rotate in order to adjust the position of the adjuster 42.

[0130] For example, the lead screw extends to both ends of the battery device 2 in the width direction of the vehicle body 30 to increase the range of movement of the adjustment member 42.

[0131] In these embodiments, through the lead screw thread engagement, the drive component 43 can convert the rotational motion into the linear motion of the adjusting component 42, thereby achieving precise displacement of the adjusting component 42 in the width direction of the vehicle body 30. This transmission method provides smooth transmission, high positioning accuracy, and good self-locking performance, effectively preventing the adjusting component 42 from undergoing unexpected displacement due to vibration or impact during vehicle 1 operation, ensuring positional stability after attitude adjustment, and improving the operational reliability of the adjusting component 40.

[0132] In some embodiments, such as Figures 4 to 8 As shown, the adjustment assembly 40 also includes a mating part 44, which is connected to the mounting chamber 31 and is spaced apart along the direction of gravity. One of the mating part 44 and the adjustment part 42 is an electromagnet, and the other of the mating part 44 and the adjustment part 42 is a magnetic element.

[0133] For example, the magnetic component is a permanent magnet or a magnetic metal block.

[0134] Optionally, the adjusting member 42 is an electromagnet and the mating member 44 is a magnetic member. When the adjusting member 42 is energized, the adjusting member 42 and the mating member 44 attract each other, thereby causing the elastic member 41 to deform and causing half of the battery device 2 to move toward the mating member 44; or the adjusting member 42 is a magnetic member and the mating member 44 is an electromagnet. When the mating member 44 is energized, the mating member 44 attracts the adjusting member 42, thereby causing half of the battery device 2 to move toward the mating member 44.

[0135] For example, two adjusting members 42 are fixed to the two halves of the battery device 2. The adjusting members 42 are electromagnets, and the mating members 44 are magnetic. The adjusting members 42 located in the two halves are supplied with currents in opposite directions to generate magnetic forces of opposite polarities, so that the two halves of the battery device 2 are subjected to forces in opposite directions, so as to adjust the tilt angle of the battery device 2 more quickly.

[0136] For example, if the adjusting member 42 is movable along the width direction of the vehicle body 30, the adjusting member 42 will first move to the target position, and then the electromagnet will be energized to drive the battery device 2 to tilt relative to the horizontal plane.

[0137] For example, when the mating part 44 is a magnetic part, the mating part 44 is a structural block independent of the wall of the mounting chamber 31, or the mating part 44 reuses the metal wall of the mounting chamber 31.

[0138] In these embodiments, the adjustment assembly 40 further includes a mating member 44, which is connected to the mounting chamber 31 and spaced apart along the direction of gravity. One of the mating member 44 and the adjustment member 42 is an electromagnet, and the other is a magnetic member. Through the magnetic interaction between the electromagnet and the magnetic member, a driving force is generated when the electromagnet is energized, causing the adjustment member 42 to displace relative to the mating member 44 in the direction of gravity, thereby driving the elastic member 41 to deform. No intermediate transmission components are required, the required installation space is small, and the assembly difficulty of the adjustment assembly 40 is reduced.

[0139] In some embodiments, such as Figures 6 to 8 As shown, the vehicle body 30 includes two mounting compartments 31, which are located on both sides of the width direction of the vehicle body 30. The vehicle 1 includes two battery devices 2, which are located in the two mounting compartments 31.

[0140] Optionally, the two mounting compartments 31 are located on both sides of the width direction of the vehicle body 30, and the two mounting compartments 31, the battery device 2 and the adjustment component 40 inside the mounting compartments 31 are symmetrically arranged to balance the center of gravity of the vehicle 1.

[0141] In these embodiments, the vehicle body 30 includes two mounting compartments 31. By independently arranging the battery device 2 on both sides of the width direction of the vehicle body 30, the weight of the battery device 2 is distributed in the width direction of the vehicle body 30, which helps to reduce the center of gravity height of the whole vehicle, reduce the lateral tilt moment of the vehicle 1 under tilting conditions, and improve the stability of the vehicle 1.

[0142] In some embodiments, such as Figures 1 to 8 As shown, vehicle 1 includes a vehicle body 30, a battery device 2, and an adjustment assembly 40. The vehicle body 30 includes two mounting compartments 31, an angle sensor 50, and a pressure sensor 60. The two mounting compartments 31 are located on both sides of the vehicle body 30 in the width direction. The battery device 2 is disposed within the mounting compartments 31. The angle sensor 50 is used to acquire the angle information between the vehicle body 30 and the horizontal plane. The adjustment assembly 40 includes an elastic element 41, an adjusting element 42, a driving element 43, and a mating element 44. The elastic element 41 is disposed on the side of the battery device 2 in the direction of gravity and is connected to the battery device 2 and the compartment wall of the mounting compartment 31. The adjusting element 42 is disposed on the battery device 2, and the mating element 44... 44 is connected to the mounting compartment 31 and is spaced apart along the direction of gravity. One of the mating parts 44 and the adjusting parts 42 is an electromagnet, and the other of the mating parts 44 and the adjusting parts 42 is a magnetic element. The adjusting parts 42 are movably arranged along the width direction of the vehicle body 30. The adjusting assembly 40 is configured to adjust the position of the adjusting parts 42 in the width direction of the vehicle body 30 based on the included angle information and pressure information, and to adjust the position of the adjusting parts 42 in the direction of gravity based on the included angle information. By moving, the elastic element 41 is deformed to adjust the tilt angle of the battery device 2 relative to the horizontal plane. The control unit is configured to adjust the output current of the battery device 2 based on the included angle information.

[0143] In these embodiments, vehicle 1 includes a vehicle body 30, a battery device 2, and an adjustment assembly 40. The vehicle body 30 has a mounting compartment 31, and the battery device 2 is disposed within the mounting compartment 31. The adjustment assembly 40 includes an elastic element 41 and an adjustment element 42. The battery device 2 is connected to the wall of the mounting compartment 31 via the elastic element 41, and the adjustment element 42 is disposed on the battery device 2. When vehicle 1 tilts, causing the battery device 2 to tilt accordingly, the adjustment element 42 moves to deform the elastic element 41, thereby actively adjusting the tilt angle of the battery device 2 relative to the horizontal plane. This improves the problems caused by the tilt of the battery device 2, such as poor electrode wetting, increased internal resistance of the battery cells 6, and easy undervoltage of the battery device 2, which can lead to vehicle 1 breakdown. This helps to enhance the output stability of the battery device 2 and improve the reliability of vehicle 1.
