Vehicle body and vehicle Technical Field

[0001] This application relates to the field of new energy vehicle technology, and more specifically, to a vehicle body and a vehicle. Background Technology

[0002] New energy vehicles have become an important part of the sustainable development of the vehicle industry due to their energy-saving and environmental protection advantages. With the development of new energy vehicles, people's requirements for the driving range of new energy vehicles are also increasing. In order to meet the needs of new energy vehicles to replenish power loss in a timely manner during driving, the solution of battery swapping to replenish power loss in a timely manner has emerged.

[0003] For new energy vehicles, improving the assembly efficiency between the battery and the vehicle body is a technical problem that urgently needs to be solved.

[0004] Summary of the Invention

[0005] This application provides a vehicle body and a vehicle, and the technical solution provided by this application can effectively improve the assembly efficiency between the battery and the vehicle body.

[0006] This application is achieved through the following technical solution:

[0007] In a first aspect, some embodiments of this application provide a vehicle body, which includes a frame and a quick-change device. The quick-change device is connected to the frame and is used for detachable connection with a battery. The quick-change device includes a locking member and a driving member, the driving member driving the locking member to move along a first direction, such that the locking member is inserted into or detached from the battery, the first direction being perpendicular to the direction of gravity.

[0008] In the above solution, the vehicle body is connected to the battery via a quick-swap device. Driven by the drive component, the locking component moves in the first direction to quickly lock or unlock the battery, reducing the assembly difficulty between the battery and the vehicle body and improving assembly efficiency. On the one hand, this can improve vehicle manufacturing efficiency or vehicle battery swapping efficiency. On the other hand, in the event of battery failure, the drive component can quickly disconnect the battery, allowing the battery to quickly separate from the frame and reducing the safety risks to the vehicle caused by battery failure.

[0009] According to some embodiments of this application, the quick-change device further includes a base connected to the vehicle frame, the base having a groove, and a locking member slidably disposed in the groove.

[0010] In the above solution, by setting a base and allowing the locking component to be slidably disposed in the groove of the base, on the one hand, the locking component can be moved stably along the first direction, thereby effectively locking or unlocking the battery, improving the assembly efficiency between the frame and the battery, which is beneficial to improving vehicle manufacturing efficiency or vehicle battery swapping efficiency. On the other hand, the base can also support the locking component, thereby effectively transferring the weight of the battery to the frame, so that there is a stable connection between the battery and the frame, thereby improving the reliability of vehicle operation.

[0011] According to some embodiments of this application, the locking member includes a body and a protrusion. The body is slidably disposed in a groove, and the protrusion is disposed on the outer peripheral surface of the body. A driving member is connected to the body to cause the protrusion to be inserted into or removed from the mounting portion of the battery.

[0012] In the above solution, by providing a protrusion on the outer peripheral surface of the main body to cooperate with the battery mounting part, the locking component and the battery have a contact area of ​​appropriate length, reducing the displacement stroke of the locking component along the first direction. This facilitates the locking component to quickly lock onto or detach from the battery under the drive of the driving component. On the one hand, this improves the assembly efficiency between the battery and the vehicle body. On the other hand, in the event of battery failure, it enables the battery to quickly detach from the frame, reducing the safety risks to the vehicle caused by battery failure.

[0013] According to some embodiments of this application, the locking member includes a plurality of protrusions, which are spaced apart along a first direction, and each protrusion is used to be inserted into a corresponding mounting portion.

[0014] In the above solution, by setting multiple protrusions to correspond one-to-one with multiple mounting parts of the battery, the locking component and the battery have a large contact area, which helps to improve the connection stability between the frame and the battery, reduce the risk of battery detachment, and improve the reliability of vehicle operation.

[0015] According to some embodiments of this application, an opening is formed on the outer peripheral surface of the base, the opening is connected to a sliding groove, and the opening is used for insertion of the mounting part.

[0016] In the above solution, by providing an opening on the outer periphery of the base, on the one hand, the opening allows the battery mounting part to be inserted so that the protrusion can be inserted into the slot of the mounting part, thereby achieving the locking of the frame and the battery; on the other hand, in the second direction, the base and the mounting part can share some space, which is beneficial to improving the compactness of the vehicle structure.

[0017] According to some embodiments of this application, the driving member includes a first pushing part and a second pushing part. Along a first direction, the first pushing part is disposed on one side of the body and the second pushing part is disposed on the other side of the body. The first pushing part is used to push the body to move toward the second pushing part, and the second pushing part is used to push the body to move toward the first pushing part.

[0018] In the above solution, by providing a first pushing part and a second pushing part on opposite sides of the locking member along the first direction, opposite thrusts are provided to the locking member, thereby effectively switching the locking or unlocking relationship between the quick-change device and the battery and improving the assembly efficiency between the battery and the vehicle body.

[0019] According to some embodiments of this application, the first pushing part includes a first air rod, and the second pushing part includes a second air rod.

[0020] In the above solution, by setting a first air rod and a second air rod on opposite sides of the locking component along the first direction, the locking component is pneumatically pushed to slide along the first direction, which can effectively switch the locking or unlocking relationship between the quick-change device and the battery, and improve the assembly efficiency between the battery and the vehicle body.

[0021] According to some embodiments of this application, along a first direction, a first groove is formed on the end face of the body opposite to the second pushing part, and a second groove is formed on the end face of the body opposite to the first pushing part. The execution end of the first pushing part is disposed in the first groove, and the execution end of the second pushing part is disposed in the second groove.

[0022] In the above solution, by forming a first groove at one end of the body along the second direction to accommodate the execution end of the first pusher, and forming a second groove at the other end of the body along the second direction to accommodate the execution end of the second pusher, the space utilization of the drive component and the locking component can be improved, making the quick-change device compact in structure, so that larger or more batteries can be installed, which is beneficial to improving the vehicle's driving range.

[0023] According to some embodiments of this application, the quick-change device further includes an elastic element disposed inside the base and connected to the protrusion.

[0024] In the above solution, by setting an elastic element inside the base, the stability of the locking component can be improved, and the risk of the locking component sliding due to external impact causing difficulty in battery assembly or causing the battery to detach from the vehicle frame can be reduced.

[0025] According to some embodiments of this application, a detonator is provided between the driving member and the locking member, the detonator being configured to push the locking member to move in a first direction by an explosion, so that the locking member is disengaged from the battery.

[0026] In the above solution, by setting a detonator between the drive component and the main body, in an emergency, the detonator can be triggered to push the locking component to move in an explosive manner, thereby releasing the connection between the locking component and the battery. This allows the battery to quickly detach from the frame, reducing the probability of vehicle safety risks caused by battery runaway, and thus making the vehicle highly reliable.

[0027] According to some embodiments of this application, the vehicle body also includes a catapult, which is disposed on the vehicle frame and is used to push the battery along the direction of gravity.

[0028] In the above solution, by setting up a catapult, an elastic force can be provided to the battery toward the ground. When the quick-change device releases the lock on the battery, the battery can quickly detach from the frame under the action of the catapult.

[0029] According to some embodiments of this application, the frame includes a connecting beam, a first crossbeam, a second crossbeam, a first longitudinal beam, and a second longitudinal beam. The first and second longitudinal beams are arranged side by side. The first crossbeam connects the first and second longitudinal beams, and the second crossbeam connects the first and second longitudinal beams. The first and second crossbeams are spaced apart. One end of the connecting beam is connected to the first crossbeam, and the other end of the connecting beam is connected to the second crossbeam. Along the direction of gravity, the connecting beam has a first surface facing the battery, and a catapult is disposed on the first surface.

[0030] In the above solution, by setting a connecting beam and placing the ejector on the connecting beam, the ejector can provide a downward elastic force to the battery from above, which facilitates the battery to quickly detach from the vehicle frame.

[0031] According to some embodiments of this application, the frame has a lower surface in the direction of gravity, and a first positioning member and a second positioning member are spaced apart in a first direction on the lower surface. The first positioning member and the second positioning member are used to position the battery respectively.

[0032] In the above solution, by setting a first positioning component and a second positioning component for positioning the battery on the lower surface of the vehicle frame, the battery can be quickly assembled into the correct position under the action of the first positioning structure and the second positioning structure, thereby enabling the quick-change device to quickly lock the battery in place, and thus effectively improving the assembly efficiency between the battery and the vehicle body.

[0033] According to some embodiments of this application, the vehicle frame has a receiving cavity for accommodating a battery, and quick-change devices are respectively provided on both sides of the receiving cavity along a second direction for detachably connecting to the opposite sides of the battery along the second direction. The first direction, the second direction, and the direction of gravity are mutually perpendicular.

[0034] In the above solution, by setting quick-change devices on both sides of the receiving cavity along the second direction, and detachably connecting them to the opposite sides of the battery along the second direction, the battery can be evenly loaded onto the frame, making the connection between the battery and the frame stable and improving the reliability of vehicle operation.

[0035] Secondly, this application also provides a vehicle, which includes the vehicle body and battery provided in the first aspect. The battery is detachably connected to a quick-change device.

[0036] In the above solution, the quick-swap device enables the battery to be efficiently assembled into or detached from the vehicle body, which is beneficial to improving vehicle manufacturing efficiency or vehicle battery swapping efficiency.

[0037] According to some embodiments of this application, the battery includes a housing, and the housing has a mounting portion on its outer side along a second direction. The mounting portion forms a slot for inserting a locking member. The first direction, the second direction, and the gravity direction are perpendicular to each other.

[0038] In the above solution, by setting a mounting part on the battery box, the battery can be effectively matched with the quick-swap device, so that the battery can be efficiently assembled into or detached from the vehicle body, which is conducive to improving vehicle manufacturing efficiency or vehicle battery swapping efficiency.

[0039] The above description is only an overview of the technical solution of this application.

[0062] Currently, new energy vehicles consist of the vehicle body and the battery. The vehicle body includes the frame, whose function includes supporting and connecting the various assemblies of the vehicle, maintaining their relatively correct positions, and bearing various loads from inside and outside the vehicle. The battery is generally mounted on the frame and provides electrical energy to the various components and equipment in the vehicle. Typically, the battery is fixed to the frame with bolts, and installation and removal of the battery are achieved by tightening the bolts. Therefore, battery installation and removal are labor-intensive and time-consuming, significantly impacting the efficiency of vehicle manufacturing and battery replacement. Furthermore, in the event of a traffic accident and battery failure, the battery cannot be quickly separated from the frame, posing a significant safety risk.

[0063] In view of this, to improve the problem of low assembly efficiency between the battery and the vehicle body, which affects the overall vehicle manufacturing efficiency or order replacement efficiency, some embodiments of this application provide a vehicle body, which includes a frame and a quick-change device. The quick-change device is connected to the frame and is used for detachable connection of the battery. The quick-change device includes a locking member and a driving member. The driving member is used to drive the locking member to move along a first direction, so that the locking member is inserted into or detached from the battery. The first direction is perpendicular to the direction of gravity.

[0064] In the above solution, the vehicle body is connected to the battery via a quick-swap device. Driven by the drive component, the locking component moves in the first direction to quickly lock or unlock the battery, reducing the assembly difficulty between the battery and the vehicle body and improving assembly efficiency. On the one hand, this can improve vehicle manufacturing efficiency or vehicle battery swapping efficiency. On the other hand, in the event of battery failure, the drive component can quickly disconnect the battery, allowing the battery to quickly separate from the frame and reducing the safety risks to the vehicle caused by battery failure.

[0065] The vehicle frame assembly disclosed in this application can be applied to, but is not limited to, passenger vehicles, commercial vehicles, and other types of vehicles. The vehicles disclosed in this application can be, but are not limited to, passenger vehicles, commercial vehicles, and other types of vehicles.

[0066] Please refer to Figure 1, which is a structural schematic diagram of a vehicle 1000 provided in some embodiments of this application. The vehicle 1000 can be a new energy vehicle, such as a pure electric vehicle, a battery-swapping hybrid electric vehicle, or a battery-swapping range-extended electric vehicle. The vehicle 1000 includes a vehicle body 100 and a battery 200. The battery 200 can be located at the bottom, front, or rear of the vehicle body 100. The battery 200 can be used to power the vehicle 1000; for example, the battery 200 can serve as the operating power source for the vehicle 1000's electrical system, such as meeting the power requirements for starting, navigation, and operation of the vehicle 1000.

[0067] The vehicle body 100 may include a frame 10, a controller 300, and a motor 400.

[0068] The frame 10 serves to support and connect the various assemblies of the vehicle 1000, ensuring that the assemblies maintain their relatively correct positions and bearing various loads inside and outside the vehicle 1000. The frame 10 can also be used to mount the battery 200, for example, the battery 200 is mounted on the frame 10. The controller 300 is used to control the battery 200 to supply power to the motor 400, for example, to meet the power needs of the vehicle 1000 during starting, navigation, and driving.

[0069] In some embodiments of this application, the battery 200 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.

[0070] This application provides a vehicle body 100 in some embodiments. Please refer to Figures 2-7. Figure 2 is a perspective view of the frame 10, quick-change device 20, and battery 200 in some embodiments of this application. Figure 3 is an exploded perspective view of the frame 10, quick-change device 20, and battery 200 in some embodiments of this application. Figure 4 is an exploded perspective view of the frame 10 and quick-change device 20 in some embodiments of this application.

Figure 6 is a perspective view of the quick-change device 20 when it is locked to the battery 200 in some embodiments of this application. Figure 7 is an exploded perspective view of the quick-change device 20 in some embodiments of this application.

[0071] The vehicle body 100 includes a frame 10 and a quick-change device 20. The quick-change device 20 is connected to the frame 10 and is used for detachable connection of the battery 200. The quick-change device 20 includes a locking member 21 and a driving member 22. The driving member 22 is used to drive the locking member 21 to move along a first direction x, so that the locking member 21 is inserted into or detached from the battery 200. The first direction x is perpendicular to the gravity direction z.

[0072] In some embodiments, the frame 10 may include a frame structure spanning the front and rear axles of the vehicle 1000. The function of the frame 10 may include supporting and connecting the various assemblies of the vehicle 1000, maintaining the assemblies in their correct relative positions, and bearing various loads inside and outside the vehicle 1000. In some embodiments, the frame 10 may include a pair of longitudinal beams, such as a first longitudinal beam 14 and a second longitudinal beam 15. The first longitudinal beam 14 and the second longitudinal beam 15 are spaced apart from each other along the transverse direction of the frame 10. The first longitudinal beam 14 and the second longitudinal beam 15 may extend longitudinally along the frame 10, i.e., the longitudinal direction of the beams is parallel to the longitudinal beams of the frame 10. In some instances, the frame 10 also includes a crossbeam disposed between and connecting the first longitudinal beam 14 and the second longitudinal beam 15. In some embodiments, the connection between the crossbeam and the first longitudinal beam 14 includes, but is not limited to, welding, riveting, threaded connections, etc., and the connection between the crossbeam and the second longitudinal beam 15 includes, but is not limited to, welding, riveting, threaded connections, etc.

[0073] In some embodiments, a receiving cavity may be formed between the two longitudinal beams, which may accommodate at least a portion of the battery 200. Exemplarily, along the gravitational direction z, a portion of the battery 200 may be located between the two longitudinal beams, i.e., within the receiving cavity, while the remaining portion of the battery 200 may be located below the two longitudinal beams.

[0074] The quick-change device 20 is designed for detachable connection with the battery 200. Compared to current threaded connections, the quick-change device 20 offers higher assembly and disassembly efficiency. The connection between the quick-change device 20 and the frame 10 includes, but is not limited to, welding, riveting, and threaded connections. For example, the quick-change device 20 has a base 23 with a back plate 231, which can be threaded to the longitudinal beam.

[0075] In some embodiments, the quick-change device 20 may be connected to the longitudinal beam or to the transverse beam.

[0076] In some embodiments, the frame 10 is equipped with a quick-change device 20, for example, the quick-change device 20 is fixed to the inner side of the first longitudinal beam 14 facing the second longitudinal beam 15, and the battery 200 and the second longitudinal beam 15 can be connected by means of snap-fit ​​or the like.

[0077] In some embodiments, the frame 10 is configured with a plurality of quick-change devices 20. For example, the first longitudinal beam 14 is provided with one, two or more quick-change devices 20 facing the inner side of the second longitudinal beam 15, and the second longitudinal beam 15 is provided with one, two or more quick-change devices 20 facing the inner side of the first longitudinal beam 14. That is, in the transverse direction of the frame 10, the opposite sides of the battery 200 are connected by corresponding quick-change devices 20.

[0078] The first direction x is parallel to the horizontal plane and perpendicular to the direction of gravity z. In some embodiments, the first direction x may be parallel to the longitudinal direction of the frame 10, and in other embodiments, the first direction x may be parallel to the transverse direction of the frame 10. Some embodiments of this application are illustrated with the example of a quick-change device 20 disposed on the inner side of the longitudinal beam, with the first direction x parallel to the longitudinal direction of the frame 10.

[0079] Please refer to Figures 5, 6, and 7. The quick-change device 20 includes a locking member 21 and a driving member 22. The driving member 22 can drive the locking member 21 to move along a first direction x. By adjusting the position of the locking member 21 along the first direction x, the locking member 21 can be inserted into the battery 200 to provide support for the battery 200 in the gravity direction z, thereby enabling the frame 10 to mount the battery 200, or the locking member 21 can be detached from the battery 200 to remove the support for the battery 200 in the gravity direction z, thereby enabling the battery 200 to be removed from the frame 10.

[0080] Optionally, the locking member 21 may include a pin that can be inserted into a pin hole of the battery 200, the pin hole of the battery 200 extending along a first direction x. For example, in the first direction x, two quick-change devices 20 are spaced apart, the battery 200 is located between the two quick-change devices, and the locking members 21 of the two quick-change devices 20 are respectively driven by a drive member 22, and can be respectively inserted into pin holes on two opposing sidewalls of the battery 200 along the first direction x.

[0081] Optionally, the locking member 21 may include a body 210 and a protrusion 211. The protrusion 211 is disposed on the circumferential surface of the body 210, and the body 210 is moved by the driving member 22. The outer surface of the battery 200 may be provided with a slot 202, the opening of which faces the quick-change device 20. Under the drive of the driving member 22, the protrusion 211 can be inserted into the slot 202 to lock the battery 200, or the protrusion 211 can be misaligned in the slot 202 under the drive of the driving member 22, thereby releasing the connection to the battery 200.

[0082] In the above scheme, the vehicle body 100 is connected to the battery 200 through the quick-change device 20. The locking member 21 can be moved in the first direction x by the drive member 22 to quickly lock or unlock the battery 200, reducing the assembly difficulty between the battery 200 and the vehicle body 100 and improving the assembly efficiency. On the one hand, this can help improve the manufacturing efficiency of the vehicle 1000 or the battery swapping efficiency of the vehicle 1000. On the other hand, when the battery 200 is out of control, the connection to the battery 200 can be quickly released by the drive member 22, so that the battery 200 can be quickly separated from the frame 10, reducing the safety risk of the vehicle 1000 caused by the battery 200 being out of control.

[0083] According to some embodiments of this application, see Figures 5-7. The quick-change device 20 also includes a base 23, which is connected to the frame 10. The base 23 has a groove in which the locking member 21 is slidably disposed.

[0084] The base 23 is a support structure for the quick-change device 20. The base 23 can provide support for the locking member 21 and enable the quick-change device 20 to be connected to the frame 10.

[0085] Optionally, referring to Figure 7, the base 23 includes a back plate 231, a slide 232, and a cover plate 233. The back plate 231 is connected to the frame 10. The connection between the back plate 231 and the frame 10 includes, but is not limited to, welding, riveting, threaded connection, or other connection methods, or the back plate 231 is integrally formed on the frame 10. The slide 232 is disposed on the surface of the back plate 231 facing away from the frame 10. The connection between the slide 232 and the back plate 231 includes, but is not limited to, welding, riveting, threaded connection, or other connection methods, or the slide 232 and the back plate 231 are integrally formed. A first recess is formed on the surface of the slide 232 facing away from the back plate 231. The first recess can extend along a first direction x and can slide and engage with the locking member 21 so that the locking member 21 can move along the first direction x. The cover plate 233 is connected to the slide block 232 on the side opposite to the back plate 231. A second recess is formed on the surface of the cover plate 233 facing the slide block 232. The first and second recesses correspond to each other and together form a groove for accommodating the locking member 21. The connection between the cover plate 233 and the slide block 232 includes, but is not limited to, welding, riveting, threaded connection or other connection methods, or the slide block 232 and the back plate 231 are integrally formed.

[0086] Optionally, the drive member 22 is disposed in the slide groove. Optionally, the drive member 22 may be partially disposed outside the base 23, and the actuating end of the drive member 22 may extend into the slide groove to connect with the locking member 21, thereby driving the locking member 21 to move.

[0087] In the above solution, by setting a base 23 and slidably setting the locking member 21 in the groove of the base 23, on the one hand, the locking member 21 can move stably along the first direction x, thereby effectively locking or unlocking the battery 200, improving the assembly efficiency between the frame 10 and the battery 200, which is beneficial to improving the manufacturing efficiency of the vehicle 1000 or the battery swapping efficiency of the vehicle 1000. On the other hand, the base 23 can also support the locking member 21, thereby effectively transferring the weight of the battery 200 to the frame 10, so that the battery 200 and the frame 10 have a stable connection relationship, thereby improving the reliability of the vehicle 1000.

[0088] According to some embodiments of this application, please refer to Figures 7 and 8. Figure 8 is a schematic diagram of the mounting portion 201 of the battery 200 in some embodiments of this application. The locking member 21 includes a body 210 and a protrusion 211. The body 210 is slidably disposed in a groove, and the protrusion 211 is disposed on the outer peripheral surface of the body 210. The driving member 22 is connected to the body 210 and is used to cause the protrusion 211 to be inserted into or removed from the mounting portion 201 of the battery 200.

[0089] The body 210 is the main body of the locking member 21, and the protrusion 211 is a component provided on the outer peripheral surface of the body 210. The protrusion 211 protrudes from the body 210 to engage with the mounting portion 201 of the battery 200. For example, the mounting portion 201 of the battery 200 is block-shaped and fixed to the outer side of the battery housing for engaging with the protrusion 211. A slot 202 is formed on the surface of the mounting portion 201 facing the quick-change device 20. The slot 202 extends along a first direction x, or the slot 202 can penetrate the mounting portion 201 along the first direction x. When the frame 10 is not carrying the battery 200, the protrusion 211 can be located in the groove. When the battery 200 needs to be carried, the battery 200 is moved along the direction of gravity z into the receiving cavity of the frame 10. The drive unit 22 is activated, causing the body 210 to move so that the protrusion 211 extends out of the groove and enters the slot 202 of the mounting part 201, thus assembling the battery 200. When the battery 200 needs to be removed from the frame 10, the drive unit 22 is activated, causing the body 210 to move so that the protrusion 211 leaves the slot 202. The battery 200 can be detached from the frame 10 by means of a robotic arm or other equipment, or by its own weight.

[0090] In the above solution, by providing a protrusion 211 on the outer peripheral surface of the body 210 to cooperate with the mounting part 201 of the battery 200, the locking member 21 and the battery 200 have a contact area of ​​appropriate length, reducing the displacement stroke of the locking member 21 along the first direction x. This facilitates the locking member 21 to quickly lock onto or detach from the battery 200 under the drive of the driving member 22. On the one hand, this can improve the assembly efficiency between the battery 200 and the vehicle body 100. On the other hand, when the battery 200 is out of control, it can enable the battery 200 to quickly detach from the frame 10, reducing the safety risk of the vehicle 1000 caused by the battery 200 being out of control.

[0091] According to some embodiments of this application, please refer to Figures 3, 6 and 7. The locking member 21 includes a plurality of protrusions 211, which are spaced apart along a first direction x, and each protrusion 211 is used to insert into a corresponding mounting portion 201.

[0092] In some embodiments, two or more protrusions 211 may be provided on the outer peripheral surface of the body 210 to correspond to two or more mounting portions 201 of the battery 200. When the battery 200 is mounted on the vehicle frame 10, the corresponding protrusion 211 can be accommodated in the slot 202 of each mounting portion 201 of the battery 200.

[0093] Optionally, the second direction y, the first direction x, and the gravity direction z are all perpendicular to each other, and the two quick-change devices 20 are arranged at intervals relative to each other along the second direction y, with the battery 200 located between the two quick-change devices 20. The battery 200 has three mounting portions 201 on each of its opposite sides along the second direction y, and each quick-change device 20's locking member 21 has three protrusions 211, each corresponding to a mounting portion 201. When the battery 200 is mounted on the vehicle frame 10, the protrusions 211 of both quick-change devices 20 are inserted into the slots 202 of their corresponding mounting portions 201.

[0094] In the above solution, by setting multiple protrusions 211 to correspond one-to-one with multiple mounting parts 201 of the battery 200, the locking member 21 and the battery 200 have a large contact area, which helps to improve the connection stability between the frame 10 and the battery 200, reduce the risk of the battery 200 falling off, and improve the reliability of the vehicle 1000.

[0095] According to some embodiments of this application, please refer to Figures 2, 5, 6 and 7. An opening 230 is formed on the outer peripheral surface of the base 23, which communicates with a sliding groove and is used for inserting the mounting part 201.

[0096] The opening 230 can expose the protrusion 211. When the mounting part 201 of the battery 200 is inserted into the opening 230, the slot 202 of the mounting part 201 can communicate with the slide. The driving member 22 drives the body 210 to move along the first direction x, so that the protrusion 211 is inserted into the slot 202.

[0097] Optionally, in the locking member 21, a plurality of slides 232 are provided on the back plate 231. The plurality of slides 232 are spaced apart along the first direction x, and each slide 232 is correspondingly provided with a cover plate 233. An opening 230 is formed between two adjacent pairs of slides 232 and cover plates 233. For example, referring to Figures 5-7, the quick-change device 20 includes four pairs of slides 232 and cover plates 233. Three openings 230 are formed between the four pairs of slides 232 and cover plates 233 for the three mounting portions 201 of the battery 200 to be inserted. The three protrusions 211 of the locking member 21 can move from the slide groove to the opening 230 under the drive of the driving part, thereby inserting into the slot 202 of the mounting portion 201, or the three protrusions 211 of the locking member 21 can leave the slot 202 and be hidden in the slide groove under the drive of the driving part.

[0098] In the above solution, by providing an opening 230 on the outer peripheral surface of the base 23, on the one hand, the opening 230 allows the mounting part 201 of the battery 200 to be inserted so that the protrusion 211 can be inserted into the slot 202 of the mounting part 201, thereby achieving the locking of the frame 10 and the battery 200; on the other hand, in the second direction y, the base 23 and the mounting part 201 can share some space, which is beneficial to improving the structural compactness of the vehicle 1000.

[0099] According to some embodiments of this application, please refer to Figures 7, 9 and 10. Figure 9 is a schematic diagram of the first pushing part 220, the base 23 and the locking member 21 in some embodiments of this application, and Figure 10 is a schematic diagram of the second pushing part 221, the base 23 and the locking member 21 in some embodiments of this application.

[0100] The driving member 22 includes a first pushing part 220 and a second pushing part 221. Along the first direction x, the first pushing part 220 is disposed on one side of the body 210 and the other side of the body 210. The first pushing part 220 is used to push the body 210 toward the second pushing part 221, and the second pushing part 221 is used to push the body 210 toward the first pushing part 220.

[0101] Along the first direction x, a first pushing part 220 is disposed on one side of the locking member 21, and a second pushing part 221 is disposed on the other side of the locking member 21. The first pushing part 220 can provide a force to the locking member 21 in the direction from the first pushing part 220 to the second pushing part 221, and the second pushing part 221 can provide a force to the locking member 21 in the direction from the second pushing part 221 to the first pushing part 220.

[0102] The first propulsion unit 220 is a drive mechanism capable of providing linear motion, including but not limited to a linear motor, pneumatic rod, hydraulic rod, or other drive mechanism. The second propulsion unit 221 is a drive mechanism capable of providing linear motion, including but not limited to a linear motor, pneumatic rod, hydraulic rod, or other drive mechanism.

[0103] Optionally, the actuating end of the first pushing part 220 may or may not be connected to the locking member 21. For example, the first pushing part 220 and the locking member 21 may not be connected, but when the first pushing part 220 is working, it can abut against the locking member 21 to push the locking member 21. Alternatively, the actuating end of the first pushing part 220 may be connected to the locking member 21, and the connection between the two may include, but is not limited to, bonding, welding, riveting, or threaded connection. Optionally, the actuating end of the first pushing part 220 and the locking member 21 may be fixed to each other or hinged to each other. The actuating end of the second pushing part 221 may or may not be connected to the locking member 21. For example, the second pushing part 221 and the locking member 21 may not be connected, but when the second pushing part 221 is working, it can abut against the locking member 21 to push the locking member 21. Alternatively, the actuating end of the second pushing part 221 may be connected to the locking member 21, and the connection between the two may include, but is not limited to, bonding, welding, riveting, or threaded connection. Optionally, the actuating end of the second pusher 221 and the locking member 21 can be fixed to each other or hinged to each other.

[0104] Optionally, the first pushing part 220 and the second pushing part 221 can propel the locking member 21 to move along the first direction x using high-pressure fluid. For example, the first pushing part 220 provides high-pressure fluid to the locking member 21 so that the locking member 21 moves toward the direction of the second pushing part 221. The second pushing part provides high-pressure fluid to the locking member 21 so that the locking member 21 moves toward the direction of the first pushing part 220.

[0105] For example, referring to Figures 5-7, when the battery 200 is not mounted, the first pushing part 220 operates, pushing the locking member 21 toward the second pushing part 221, so that the protrusion 211 is located in the groove, opening the opening 230. When the battery 200 is mounted, the mounting part 201 of the battery 200 is accommodated in the opening 230, and the second pushing part 221 operates, pushing the locking member 21 toward the first pushing part 220, so that the protrusion 211 moves to the opening 230 and is inserted into the slot 202 of the mounting part 201.

[0106] In some embodiments, when the first pushing part 220 pushes the locking member 21 toward the second pushing part 221, the second pushing part 221 does not provide thrust, and the second pushing part 221 allows the locking member 21 to move toward the second pushing part 221. Similarly, when the second pushing part 221 pushes the locking member 21 toward the first pushing part 220, the first pushing part 220 does not provide thrust, and the first pushing part 220 allows the locking member 21 to move toward the first pushing part 220.

[0107] For example, the first pushing part 220 and the second pushing part 221 each include a pneumatic rod. The air outlet of the first pushing part 220 is disposed in a slide groove and faces the locking member 21. The air outlet of the second pushing part 221 is disposed in a slide groove and faces the locking member 21.

[0108] When the battery 200 is not attached, an external air source supplies air to the first pushing part 220, while the second pushing part 221 is either not supplied or vents. The high-pressure gas provided by the first pushing part 220 pushes the locking member 21 toward the second pushing part 221. When the battery 200 is attached, the mounting part 201 of the battery 200 is accommodated in the opening 230. An external air source supplies air to the second pushing part 221, while the first pushing part 220 is either not supplied or vents. The high-pressure gas provided by the second pushing part 221 pushes the locking member 21 toward the first pushing part 220, causing the protrusion 211 to move to the opening 230 and insert into the slot 202 of the mounting part 201. The external air source is then closed, completing the fixing of the battery 200. For example, a one-way valve can be provided between the second pushing part 221 and the external air source so that when the external air source is closed, the second pushing part 221 can maintain the current position of the locking member 21.

[0109] In the above solution, by providing a first pushing part 220 and a second pushing part 221 on opposite sides of the locking member 21 along the first direction x, opposite thrusts are provided to the locking member 21, thereby effectively switching the locking or unlocking relationship between the quick-change device 20 and the battery 200 and improving the assembly efficiency between the battery 200 and the vehicle body 100.

[0110] In other embodiments, the drive member 22 may be a mechanism capable of providing linear reciprocating motion. The drive member 22 may be disposed on one side of the locking member 21 and connected to the locking member 21, and the locking member 21 may be reciprocated along the first direction x by providing push and pull forces to the locking member 21.

[0111] According to some embodiments of this application, please refer to FIG7, the first push part 220 includes a first air rod 2200, and the second push part 221 includes a second air rod 2210.

[0112] In some embodiments, the first gas spring 2200 can provide high-pressure gas to the locking member 21, pointing from the first push portion 220 to the second push portion 221, so that the locking member 21 can move toward the second push portion 221. The second gas spring 2210 can provide high-pressure gas to the locking member 21, pointing from the second push portion 221 to the first push portion 220, so that the locking member 21 can move toward the first push portion 220.

[0113] Optionally, the dimension of the slide groove along the first direction x is larger than the dimension of the locking member 21 along the first direction x. The air outlet of the first air rod 2200 and one end of the locking member 21 are both located in the slide groove, with the air outlet facing the locking member 21. The air outlet of the second air rod 2210 and the other end of the locking member 21 are both located in the slide groove, with the air outlet facing the locking member 21.

[0114] Referring to Figure 7, the first pushing unit 220 includes a first air rod 2200, a first air rod seat 2201, and a first connector 2202. The first air rod 2200 is connected to the first air rod seat 2201, which is connected to the base 23. The first connector 2202 is disposed on the first air rod seat 2201 and is used to connect to an external air source, which provides high-pressure gas to the first air rod 2200 through the first connector 2202. The second pushing unit 221 includes a second air rod 2210, a second air rod seat 2211, and a second connector 2212. The second air rod 2210 is connected to the second air rod seat 2211, which is connected to the base 23. The second connector 2212 is disposed on the second air rod seat 2211 and is used to connect to an external air source, which provides high-pressure gas to the second air rod 2210 through the second connector 2212.

[0115] In the above solution, by setting a first air rod 2200 and a second air rod 2210 on opposite sides of the locking member 21 along the first direction x, the locking member 21 is pneumatically pushed to slide along the first direction x, which can effectively switch the locking or unlocking relationship between the quick-change device 20 and the battery 200, and improve the assembly efficiency between the battery 200 and the vehicle body 100.

[0116] According to some embodiments of this application, please refer to Figures 7, 9 and 10. Along the first direction x, the body 210 has a first groove 2100 formed on the end face opposite to the second pushing part 221, and the body 210 has a second groove 2101 formed on the end face opposite to the first pushing part 220. The execution end of the first pushing part 220 is disposed in the first groove 2100, and the execution end of the second pushing part 221 is disposed in the second groove 2101.

[0117] In some embodiments, the body 210 has a first groove 2100 and a second groove 2101 formed at opposite ends along the first direction x. The first groove 2100 can accommodate at least a portion of the execution end of the first pusher 220, and the second groove 2101 can accommodate at least a portion of the execution end of the second pusher 221.

[0118] Optionally, the first pushing unit 220 includes a first air rod 2200, the air outlet of which may be located in the first groove 2100. The first air rod 2200 is slidably disposed in the first groove 2100, and a first sealing member 2203 is provided between the outer peripheral surface of the first air rod 2200 and the inner peripheral surface of the first groove 2100. An external air source provides high-pressure gas to the first air rod 2200, and the high-pressure gas enters the first groove 2100 and pushes the locking member 21. The second pushing unit 221 includes a second air rod 2210, the air outlet of which may be located in the second groove 2101. The second air rod 2210 is slidably disposed in the second groove 2101, and a second sealing member 2213 is provided between the outer peripheral surface of the second air rod 2210 and the inner peripheral surface of the second groove 2101. An external air source provides high-pressure gas to the second air rod 2210, and the high-pressure gas enters the second groove 2101 and pushes the locking member 21.

[0119] In the above solution, by forming a first groove 2100 at one end of the body 210 along the second direction y to accommodate the execution end of the first pusher 220, and forming a second groove 2101 at the other end of the body 210 along the second direction y to accommodate the execution end of the second pusher 221, the space utilization of the drive member 22 and the locking member 21 can be improved, making the quick-change device 20 compact in structure, so that a larger or more numerous battery 200 can be installed, which is beneficial to improving the vehicle's 1000-kilometer range.

[0120] According to some embodiments of this application, please refer to FIG7, the quick-change device 20 further includes an elastic element 24, which is disposed inside the base 23 and connected to the protrusion 211.

[0121] The elastic element 24 is a structure with elastic characteristics. For example, the elastic element 24 includes a spring.

[0122] An elastic member 24 is disposed between the base 23 and the protrusion 211, and the elastic member 24 is capable of providing an elastic force to the protrusion 211 along a first direction x. Exemplarily, the elastic member 24 is disposed in a groove, and a stop is provided in the second recess of the cover plate 233. One end of the elastic member 24 is connected to the stop, and the other end of the elastic member 24 is used to abut against the side of the protrusion 211 opposite to the first pushing part 220, so as to provide an elastic force to the locking member 21 from the second pushing part 221 toward the first pushing part 220, causing the protrusion 211 to tend to insert into the slot 202 of the mounting part 201.

[0123] In some embodiments, the quick-change device 20 may include a plurality of elastic elements 24. For example, the number of elastic elements 24 may be two, and the two elastic elements 24 are spaced apart along a first direction x.

[0124] In the above solution, by setting an elastic element 24 inside the base 23, the stability of the locking element 21 can be improved, and the risk of the locking element 21 sliding due to external impact causing difficulty in assembling the battery 200 or causing the battery 200 to detach from the frame 10 can be reduced.

[0125] According to some embodiments of this application, please refer to Figures 7 and 11, where Figure 11 is an enlarged view of point A in Figure 9. A detonator 25 is disposed between the driving member 22 and the locking member 21. The detonator 25 is configured to push the locking member 21 to move along a first direction x by detonation, so that the locking member 21 is disengaged from the battery 200.

[0126] The detonator 25 is a controllable detonation mechanism, exemplarily capable of detonating upon receiving an execution command.

[0127] Optionally, the detonator 25 can be disposed in the detonation mechanism between the first pushing part 220 and the locking part 21. Referring to Figure 11, the detonator 25 includes a detonating body 250 and a cable 251. The detonating body 250 is located in the first groove 2100 and disposed on the outer peripheral surface of the first gas cylinder 2200. The detonating body 250 may include a detonating head and an explosive charge. The detonating head may include structures such as an electric spark plug and electrodes. The explosive charge can be an explosive; generally, the explosive charge may include a mixture containing substances such as sodium neonate lead, capable of rapidly generating high-temperature, high-pressure gas. A perforation is formed in the wall of the first gas cylinder 2200, and the cable 251 runs through the perforation. One end of the cable 251 is connected to the detonating body 250, and the other end of the cable 251 is connected to the vehicle end. The vehicle can send a command to the detonator 250 via cable 251. For example, when the vehicle 1000 is involved in a collision, the collision sensor sends a signal to the electronic control unit (ECU), which then sends a signal to the detonator. The spark plug of the detonator generates an electric spark, igniting the explosive charge. The explosive charge explodes rapidly, generating high-temperature and high-pressure gas, which pushes the locking component 21 to move.

[0128] In the above solution, by setting a detonator 25 between the drive component 22 and the main body 210, in an emergency, the detonator 25 can be triggered to push the locking component 21 to move in an explosive manner, thereby releasing the connection between the locking component 21 and the battery 200. This allows the battery 200 to quickly detach from the frame 10, reducing the probability of safety risks to the vehicle 1000 due to the loss of control of the battery 200, and thus making the driving reliability of the vehicle 1000 high.

[0129] According to some embodiments of this application, the vehicle body 100 also includes a catapult 30, which is disposed on the frame 10 and is used to push the battery 200 along the direction of gravity z.

[0130] One end of the ejector 30 is connected to the frame 10 to provide an elastic force along the direction of gravity z to the battery 200. Optionally, the ejector 30 may include a compressible and rebounding device such as a metal spring, a gas spring, or an elastic gel.

[0131] In the above scheme, by setting the ejector 30, an elastic force towards the ground can be provided to the battery 200. When the quick-change device 20 releases the lock on the battery 200, the battery 200 can quickly detach from the frame 10 under the action of the ejector 30.

[0132] According to some embodiments of this application, please refer to FIG4. The frame 10 includes a connecting beam 11, a first crossbeam 12, a second crossbeam 13, a first longitudinal beam 14, and a second longitudinal beam 15. The first longitudinal beam 14 and the second longitudinal beam 15 are arranged side by side. The first crossbeam 12 connects the first longitudinal beam 14 and the second longitudinal beam 15. The second crossbeam 13 connects the first longitudinal beam 14 and the second longitudinal beam 15. The first crossbeam 12 and the second crossbeam 13 are spaced apart. One end of the connecting beam 11 is connected to the first crossbeam 12, and the other end of the connecting beam 11 is connected to the second crossbeam 13. Along the direction of gravity z, the connecting beam 11 has a first surface facing the battery 200, and the ejector 30 is disposed on the first surface.

[0133] Optionally, the first longitudinal beam 14 and the second longitudinal beam 15 extend along the first direction x, the first longitudinal beam 14 and the second longitudinal beam 15 are arranged side by side and spaced apart along the second direction y, and the first crossbeam 12 and the second crossbeam 13 are arranged side by side and spaced apart along the second direction y.

[0134] The connecting beam 11 is a beam structure disposed between two first crossbeams 12 and second crossbeams 13. One end of the connecting beam 11 is disposed on the first crossbeam 12, and the other end of the connecting beam 11 is disposed on the second crossbeam 13. When the battery 200 is mounted on the vehicle frame 10, along the direction of gravity z, the battery 200 is located below the connecting beam 11. The first surface of the connecting beam 11 facing the battery 200 is provided with a catapult 30, and the battery 200 can compress the catapult 30.

[0135] Optionally, there can be multiple connecting beams 11, and each connecting beam 11 is provided with one or more ejector elements 30. For example, referring to Figures 3 and 4, two connecting beams 11 are spaced apart along the second direction y, and each connecting beam 11 is provided with two ejector elements 30.

[0136] In the above scheme, by setting a connecting beam 11 and setting the ejector 30 on the connecting beam 11, the ejector 30 can provide a downward elastic force to the battery 200 from above, which is conducive to the battery 200 quickly detaching from the frame 10.

[0137] According to some embodiments of this application, please refer to FIG3. The frame 10 has a lower surface in the gravity direction z. The lower surface is provided with a first positioning member 16 and a second positioning member (not shown in the figure) at intervals in the second direction y. The first positioning member 16 and the second positioning member are used to position the battery 200 respectively. The first direction x, the second direction y and the gravity direction z are perpendicular to each other.

[0138] In some embodiments, the lower surface of the frame 10 may be provided with a positioning element for positioning the battery 200.

[0139] Positioning components include, but are not limited to, positioning pins, positioning grooves, or other positioning structures that can cooperate with the battery 200.

[0140] Optionally, the mounting portion 201 is disposed on one side of the battery 200 along the second direction y, and positioning mating portions 203 may be disposed on opposite sides of the battery 200 along the first direction x. The two positioning mating portions 203 respectively engage with the first positioning member 16 and the second positioning member. For example, the first positioning member 16 and the second positioning member are positioning pins, and the positioning mating portion 203 may include a positioning block and a positioning groove formed in the positioning block, into which the positioning pin can be inserted.

[0141] In the above scheme, by setting a first positioning member 16 and a second positioning member on the lower surface of the frame 10 for positioning the battery 200, the battery 200 is quickly assembled into the correct position under the action of the first positioning structure and the second positioning structure, thereby enabling the quick-change device 20 to quickly lock the battery 200, and thus effectively improving the assembly efficiency between the battery 200 and the vehicle body 100.

[0142] According to some embodiments of this application, please refer to FIG3. The frame 10 has a receiving cavity for accommodating the battery 200. Quick-change devices 20 are respectively provided on both sides of the receiving cavity along the second direction y for detachably connecting to the opposite sides of the battery 200 along the second direction y. The first direction x, the second direction y, and the gravity direction z are all perpendicular to each other.

[0143] In some embodiments, the frame 10 has a plurality of quick-change devices 20, which are respectively arranged at intervals along a second direction y, so as to be able to cooperate with the battery 200 on both sides along the second direction y. For example, a quick-change device 20 is provided on the inner side of the first longitudinal beam 14 and a quick-change device 20 is provided on the inner side of the second longitudinal beam 15.

[0144] In the above scheme, by setting quick-change devices 20 on both sides of the receiving cavity along the second direction y, and detachably connecting them to the opposite sides of the battery 200 along the second direction y, the battery 200 can be evenly loaded onto the frame 10, making the connection between the battery 200 and the frame 10 stable, which is beneficial to improving the driving reliability of the vehicle 1000.

[0145] This application also provides a vehicle 1000, which includes the vehicle body 100 and battery 200 described above. The battery 200 is detachably connected to a quick-change device 20.

[0146] In the above scheme, the quick-swap device 20 enables the battery 200 to be efficiently assembled onto or detached from the vehicle body 100, which is beneficial to improving the manufacturing efficiency of the vehicle 1000 or the battery swapping efficiency of the vehicle 1000.

[0147] According to some embodiments of this application, please refer to FIG3. The battery 200 includes a housing. The outer side of the housing along the second direction y is provided with a mounting portion 201. The mounting portion 201 forms a slot 202 for the locking member 21 to be inserted.

[0148] In the above solution, by providing a mounting part 201 on the housing of the battery 200, the battery 200 can be effectively matched with the quick-swap device 20, so that the battery 200 can be efficiently assembled on or detached from the vehicle body 100, which is beneficial to improving the manufacturing efficiency of the vehicle 1000 or improving the battery swapping efficiency of the vehicle 1000.

[0149] According to some embodiments of this application, please refer to Figures 2-11, a vehicle body 100 is provided. The vehicle body 100 includes a frame 10 and a quick-swap device 20, which is used to detachably connect to a battery 200, so that the battery 200 can be mounted on the frame 10, and the vehicle body 100 can have a battery swapping function.

[0150] The battery 200 has three mounting portions 201 formed on two opposing sides along the second direction y. The three mounting portions 201 are spaced apart along the first direction x. Each mounting portion 201 has a slot 202.

[0151] The frame 10 includes a connecting beam 11, a first crossbeam 12, a second crossbeam 13, a first longitudinal beam 14, and a second longitudinal beam 15.

[0152] The first longitudinal beam 14 and the second longitudinal beam 15 extend along the first direction x, and are arranged side by side along the second direction y. The first crossbeam 12 and the second crossbeam 13 are respectively arranged between the first longitudinal beam 14 and the second longitudinal beam 15, and are spaced apart along the first direction x. A connecting beam 11 connects the first crossbeam 12 and the second crossbeam 13, and the two connecting beams 11 are spaced apart along the second direction y.

[0153] There are two quick-change devices 20, one of which is located on the inner side of the first longitudinal beam 14, and the other is located on the inner side of the second longitudinal beam 15.

[0154] The quick-change device 20 includes a base 23, a locking element 21, a first pushing part 220, and a second pushing part 221.

[0155] The base 23 has a groove and an opening 230 that connects to the groove. Three openings 230 are spaced apart along a first direction x, and are used for insertion of the mounting portion 201 of the battery 200. The locking member 21 includes a body 210 and three protrusions 211 disposed on the body 210, spaced apart along the first direction x. The locking member 21 is slidably disposed in the groove. A first pushing portion 220 and a second pushing portion 221 are respectively disposed on both sides of the locking member 21 along the first direction x, for pushing the locking member 21 to move along the first direction x, so that the protrusions 211 can move to the opening 230 to be inserted into the slot 202 or withdraw from the slot 202 to be accommodated in the groove.

[0156] The first pushing part 220 includes a first air rod 2200 for providing high-pressure air to the locking member 21, causing the locking member 21 to move toward the second pushing part 221, thereby causing the protrusion 211 to disengage from the slot 202 and be received in the slide groove. The second pushing part 221 includes a second air rod 2210 for providing high-pressure air to the locking member 21, causing the locking member 21 to move toward the first pushing part 220, thereby causing the protrusion 211 to be inserted into the slot 202.

[0157] A detonator 25 is provided between the first gas spring 2200 and the body 210 of the locking member 21. The detonator 25 is configured to push the locking member 21 toward the second pusher 221 by detonation, so that the protrusion 211 is disengaged from the slot 202 and the locking member 21 is disengaged from the battery 200.

[0158] A catapult 30 is provided on the side of the connecting beam 11 facing the battery 200. The catapult 30 is used to provide the battery 200 with an elastic force along the direction of gravity z.

[0159] In the above scheme, the vehicle body 100 is connected to the battery 200 through the quick-change device 20. The locking member 21 can be moved in the first direction x by the drive member 22 to quickly lock or unlock the battery 200, reducing the assembly difficulty between the battery 200 and the vehicle body 100 and improving the assembly efficiency. On the one hand, this can help improve the manufacturing efficiency of the vehicle 1000 or the battery swapping efficiency of the vehicle 1000. On the other hand, when the battery 200 is out of control, the connection to the battery 200 can be quickly released by the drive member 22, so that the battery 200 can be quickly separated from the frame 10, reducing the safety risk of the vehicle 1000 caused by the battery 200 being out of control.

[0160] For example, the technical solution provided above enables the vehicle 1000 having the vehicle body 100 to have the following effects:

[0161] 1. When vehicle 1000 encounters an unavoidable collision due to an emergency, if the system anticipates this in advance and the processing time is relatively long, the vehicle end will cause the first air spring 2200 to vent, the second air spring 2210 to vent, the locking component 21 to move, and the protrusion 211 to exit the slot 202, thereby unlocking the battery 200. The battery 200 will then be ejected by the ejector component 30, thus completing the disposal of the battery 200.

[0162] 2. When vehicle 1000 is directly involved in a severe collision, the safety airbag is triggered, the detonator 25 is triggered and detonated, directly pushing the locking component 21 to slide, unlocking the battery 200. The battery 200 is ejected under the action of the ejector 30, completing the disposal of the battery 200.

[0163] Third, when the vehicle 1000 is involved in a high-speed hard collision, the locking component 21 can slide forward (towards the second pusher 221) under the action of the powerful impact force to automatically unlock itself, providing a last line of defense against detonation failure. The battery 200 is ejected under the action of the ejector component 30, completing the disposal of the battery 200.

[0164] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
