[0054] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0055] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "attached" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0056] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0057] The term "multiple" in this application refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces).

[0058] In some embodiments, the battery may be a battery module. When there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.

[0059] In some embodiments, the battery may be a battery pack, which includes a case and battery cells, wherein the battery cells or battery modules are housed in the case.

[0060] In some embodiments, the battery cells may be secondary batteries, which are batteries that can be recharged to activate their active materials after discharge and continue to be used. The battery cells may be lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-metal hydride batteries, nickel-cadmium batteries, lead-acid batteries, and the like, although this disclosure is not intended to limit this.

[0061] Currently, new energy vehicles consist of a vehicle body and a battery. The vehicle body includes a frame, which supports and connects the vehicle's various assemblies, ensuring they maintain relative positioning and withstands various loads inside and outside the vehicle. Batteries are typically mounted on the frame to provide power to the various components and equipment within the vehicle. Typically, batteries are secured to the frame with bolts, which are then installed and removed by tightening the bolts. This makes battery installation and removal 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 loss of control, the battery cannot be quickly separated from the frame, posing a significant safety risk.

[0062] In view of this, to improve the problem of low assembly efficiency between the battery and the vehicle body, which affects the efficiency of vehicle manufacturing or order replacement, some embodiments of the present 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 to detachably connect the battery. The quick-change device includes a locking member and a driving member, the driving member being used to drive the locking member to move in a first direction to insert or remove the locking member from the battery, the first direction being perpendicular to the direction of gravity.

[0063] In the above scheme, the vehicle body is connected to the battery through a quick-change device, and the locking part can be moved in the first direction by the driving part to quickly lock or unlock the battery, thereby reducing the difficulty of assembly between the battery and the vehicle body and improving the assembly efficiency. On the one hand, it can be beneficial to improve the vehicle manufacturing efficiency or the vehicle battery replacement efficiency. On the other hand, when the battery is out of control, the connection relationship with the battery can be quickly released by the driving part, so that the battery can be quickly separated from the frame, reducing the safety risk of the vehicle caused by battery loss of control.

[0064] The vehicle frame assembly disclosed in the embodiments of the present application may be applied to, but not limited to, passenger vehicles, commercial freight vehicles, and vehicles of other natures. The vehicle disclosed in the embodiments of the present application may be applied to, but not limited to, passenger vehicles, commercial freight vehicles, and vehicles of other natures.

[0065] Please refer to the figure, Figure 1A schematic structural diagram of a vehicle 1000 provided for some embodiments of the present application. The vehicle 1000 may be a new energy vehicle, which may be a pure electric vehicle, a hybrid vehicle with a swappable battery, or an extended-range vehicle with a swappable battery, etc. The vehicle 1000 includes a vehicle body 100 and a battery 200. The battery 200 may be disposed at the bottom, head, or tail of the vehicle body 100. The battery 200 may be used to power the vehicle 1000. For example, the battery 200 may serve as an operating power source for the vehicle 1000 and may be used for the circuit system of the vehicle 1000, such as for the working power requirements during startup, navigation, and operation of the vehicle 1000.

[0066] The vehicle body 100 may include a frame 10 , a controller 300 , and a motor 400 .

[0067] The vehicle frame 10 supports and connects the various assemblies of the vehicle 1000, ensuring they maintain their relative position and bearing various loads both inside and outside the vehicle 1000. The frame 10 can also be used to mount the battery 200, for example, by mounting the battery 200 on the frame 10. The controller 300 controls the battery 200 to power the motor 400, for example, to meet the power requirements of starting, navigating, and driving the vehicle 1000.

[0068] In some embodiments of the present application, the battery 200 can serve not only as an operating power source for the vehicle 1000, but also as a driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0069] Some embodiments of the present application provide a vehicle body 100, see Figure 2-Figure 7 , Figure 2 This is a three-dimensional diagram of the frame 10, the quick-change device 20, and the battery 200 in some embodiments of the present application. Figure 3 This is a perspective exploded view of the frame 10, the quick-change device 20, and the battery 200 in some embodiments of the present application. Figure 4 This is a perspective exploded view of the frame 10 and the quick-change device 20 in some embodiments of the present application. Figure 5 This is a three-dimensional diagram of the quick-change device 20 when it is separated from the battery 200 in some embodiments of the present application. Figure 6 This is a three-dimensional diagram of the quick-change device 20 in some embodiments of the present application when the quick-change device 20 is locked to the battery 200. Figure 7 1 is a perspective exploded view of the quick-change device 20 in some embodiments of the present application.

[0070] 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 to detachably connect a 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, thereby inserting or removing the locking member 21 from the battery 200. The first direction x is perpendicular to the direction of gravity z.

[0071] In some embodiments, the vehicle frame 10 may comprise a frame-like structure spanning the front and rear axles of the vehicle 1000. The functions of the vehicle frame 1000 may include supporting and connecting the various assemblies of the vehicle 1000, ensuring that the assemblies maintain relative correct positioning, and bearing various loads both inside and outside the vehicle 1000. In some embodiments, the vehicle frame 10 may comprise a pair of longitudinal beams, such as a first longitudinal beam 14 and a second longitudinal beam 15. The first and second longitudinal beams 14, 15 are spaced apart from each other in the transverse direction of the vehicle frame 10. The first and second longitudinal beams 14, 15 may extend longitudinally of the vehicle frame 10, i.e., the longitudinal directions of the longitudinal beams are parallel to the longitudinal beams of the vehicle frame 10. In some examples, the vehicle frame 10 further comprises a crossbeam disposed between and connecting the first and second longitudinal beams 14, 15. In some embodiments, the crossbeam may be connected to the first longitudinal beam 14 by, but not limited to, welding, riveting, or screwing, and the crossbeam may be connected to the second longitudinal beam 15 by, but not limited to, welding, riveting, or screwing.

[0072] In some embodiments, a receiving cavity may be formed between the two longitudinal beams, and the receiving cavity may accommodate at least a portion of the battery 200. For example, along the gravity direction z, a portion of the battery 200 may be located between the two longitudinal beams, that is, in the receiving cavity, and the remaining portion of the battery 200 may be located below the two longitudinal beams.

[0073] The quick-change device 20 is designed to be removably connected to the battery 200. Compared to existing threaded connections, the quick-change device 20 is more efficient to assemble and disassemble. Connections between the quick-change device 20 and the frame 10 include, but are not limited to, welding, riveting, and screw connections. For example, the quick-change device 20 comprises a base 23 with a backplate 231 , which can be secured to the longitudinal rail via screws.

[0074] In some embodiments, the quick-change device 20 may be connected to a longitudinal beam or a transverse beam.

[0075] 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. The battery 200 and the second longitudinal beam 15 can be connected by snapping or other means.

[0076] In some embodiments, the frame 10 is equipped with multiple quick-change devices 20. For example, one, two, or more quick-change devices 20 are provided on the inner side of the first longitudinal beam 14 facing the second longitudinal beam 15, and one, two, or more quick-change devices 20 are provided on the inner side of the second longitudinal beam 15 facing 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.

[0077] The first direction x is parallel to the horizontal plane and perpendicular to the gravity direction z. In some embodiments, the first direction x can be parallel to the longitudinal direction of the frame 10. In other embodiments, the first direction x can be parallel to the transverse direction of the frame 10. In some embodiments of the present application, the quick-change device 20 is disposed on the inner side of the longitudinal beam, and the first direction x is parallel to the longitudinal direction of the frame 10.

[0078] See Figure 5 、 Figure 6 and Figure 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 direction of gravity z, thereby allowing the frame 10 to mount the battery 200. Alternatively, the locking member 21 can be disengaged from the battery 200 to remove support for the battery 200 in the direction of gravity z, thereby allowing the battery 200 to be removed from the frame 10.

[0079] Optionally, the locking member 21 may include a latch that can be inserted into a pin hole of the battery 200. The pin hole of the battery 200 can extend along the first direction x. For example, in the first direction x, two quick-change devices 20 are spaced apart, with the battery 200 located between the two quick-change devices. The locking members 21 of the two quick-change devices 20 are driven by the driving member 22 and can be inserted into pin holes on two opposing side walls of the battery 200 along the first direction x.

[0080] Optionally, the locking member 21 may include a body 210 and a protrusion 211. The protrusion 211 is disposed on the circumference 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, with the notch of the slot 202 facing the quick-change device 20. The protrusion 211 can be inserted into the slot 202 under the drive of the driving member 22 to lock the battery 200, or the protrusion 211 can be misaligned with the slot 202 under the drive of the driving member 22 to release the battery 200.

[0081] In the above scheme, the vehicle body 100 is connected to the battery 200 through the quick-change device 20, and the locking part 21 can be moved in the first direction x by the driving part 22 to quickly lock the battery 200, or unlock the battery 200, thereby reducing the assembly difficulty between the battery 200 and the vehicle body 100 and improving the assembly efficiency. On the one hand, it can be beneficial to improve the manufacturing efficiency of the vehicle 1000, or to improve the battery replacement efficiency of the vehicle 1000. On the other hand, when the battery 200 is out of control, the connection relationship with the battery 200 can be quickly released by the driving part 22, so that the battery 200 can be quickly separated from the frame 10, thereby reducing the safety risk of the vehicle 1000 caused by the loss of control of the battery 200.

[0082] According to some embodiments of the present application, see Figure 5-Figure 7 The quick-change device 20 further includes a base 23 connected to the vehicle frame 10 . The base 23 is formed with a slide groove, and the locking member 21 is slidably disposed in the slide groove.

[0083] The base 23 is a supporting structure of 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 vehicle frame 10 .

[0084] Alternatively, see 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, screw connection, or other connection methods, or the back plate 231 is integrally formed with 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, screw 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 the first direction x and can slidably cooperate with the locking member 21 to enable the locking member 21 to move along the first direction x. The cover plate 233 is connected to the side of the slide 232 facing away from the back plate 231. A second recess is formed on the surface of the cover plate 233 facing the slide 232. The first recess and the second recess correspond to each other and together form a slide groove for accommodating the locking member 21. The connection between the cover plate 233 and the slide 232 includes, but is not limited to, welding, riveting, screw connection, or other connection methods, or the slide 232 and the back plate 231 can be integrally formed.

[0085] Optionally, the driving member 22 is disposed in the chute. Optionally, the driving member 22 can be partially disposed outside the base 23, and the execution end of the driving member 22 can extend into the chute to connect with the locking member 21, thereby driving the locking member 21 to move.

[0086] In the above scheme, by setting the base 23 and making the locking component 21 slidably set in the slide groove of the base 23, on the one hand, the locking component 21 can be stably moved 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, and facilitating the improvement of the manufacturing efficiency of the vehicle 1000, or facilitating the improvement of the battery replacement efficiency of the vehicle 1000. On the other hand, the base 23 can also support the locking component 21, thereby effectively transmitting the gravity 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 driving reliability of the vehicle 1000.

[0087] According to some embodiments of this application, see Figure 7 and Figure 8 , Figure 8 Schematic diagram of the mounting portion 201 of the battery 200 in some embodiments of the present application. The locking member 21 includes a body 210 and a protrusion 211. The body 210 is slidably disposed in a slide groove. The protrusion 211 is disposed on the outer circumference of the body 210. The driving member 22 is connected to the body 210 and is used to insert the protrusion 211 into or remove the mounting portion 201 of the battery 200.

[0088] The body 210 is the main body of the locking member 21. The protrusion 211 is a component disposed on the outer circumference of the body 210. The protrusion 211 protrudes from the body 210 to mate 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 200 casing to mate 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 the first direction x, or the slot 202 can penetrate the mounting portion 201 along the first direction x. When the battery 200 is not mounted on the frame 10, the protrusion 211 can be located in the chute. When the battery 200 needs to be mounted, the battery 200 is moved along the gravity direction z into the accommodating cavity of the frame 10. The driving member 22 is activated, causing the body 210 to move, driving the protrusion 211 to extend out of the chute and enter the slot 202 of the mounting portion 201, thereby completing the installation of the battery 200. When the battery 200 needs to be removed from the frame 10, the driving member 22 is activated, causing the body 210 to move, driving the protrusion 211 to leave the slot 202. The battery 200 can be removed from the frame 10 by a device such as a robot or by the battery 200 itself under its own weight.

[0089] In the above scheme, by providing a protrusion 211 on the outer peripheral surface of the main body 210 to cooperate with the installation portion 201 of the battery 200, a contact area of ​​appropriate length is provided between the locking member 21 and the battery 200, thereby reducing the displacement stroke of the locking member 21 along the first direction x, which is conducive to the locking member 21 quickly locking the battery 200 or falling off the battery 200 under the drive of the driving member 22. On the one hand, it can improve the assembly efficiency between the battery 200 and the vehicle body 100. On the other hand, when the battery 200 loses control, the battery 200 can be quickly detached from the frame 10, thereby reducing the safety risk of the vehicle 1000 caused by the loss of control of the battery 200.

[0090] According to some embodiments of this application, see Figure 3 、 Figure 6 and Figure 7 The locking member 21 includes a plurality of protrusions 211 , which are spaced apart along the first direction x. Each protrusion 211 is configured to be inserted into a corresponding mounting portion 201 .

[0091] In some embodiments, two or more protrusions 211 may be provided on the outer circumference of the body 210 to correspond to the two or more mounting portions 201 of the battery 200. When the battery 200 is mounted on the vehicle frame 10, the slot 202 of each mounting portion 201 of the battery 200 may accommodate a corresponding protrusion 211.

[0092] Optionally, the second direction y, the first direction x, and the direction of gravity z are mutually perpendicular. Two quick-change devices 20 are spaced apart relative to each other along the second direction y, with the battery 200 located between the two quick-change devices 20. Three mounting portions 201 are provided on opposite sides of the battery 200 along the second direction y. The locking member 21 of each quick-change device 20 is provided with three protrusions 211, with each protrusion 211 corresponding to each mounting portion 201. When the battery 200 is mounted on the frame 10, the protrusions 211 of each quick-change device 20 are inserted into the slots 202 of the corresponding mounting portion 201.

[0093] In the above solution, by providing multiple protrusions 211 to correspond one-to-one with the multiple mounting portions 201 of the battery 200, a larger contact area is provided between the locking member 21 and the battery 200, which is beneficial to improving the connection stability between the frame 10 and the battery 200, reducing the risk of the battery 200 falling off, and improving the reliability of the vehicle 1000.

[0094] According to some embodiments of this application, see Figure 2 、 Figure 5 、 Figure 6 and Figure 7 An opening 230 is formed on the outer peripheral surface of the base 23 , and the opening 230 is connected to the slide groove, and the opening 230 is used for the installation portion 201 to be inserted.

[0095] The opening 230 can expose the protrusion 211. When the mounting portion 201 of the battery 200 is inserted into the opening 230, the slot 202 of the mounting portion 201 can be connected to the slide groove, and 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.

[0096] Optionally, in the locking member 21, a plurality of slides 232 are provided on the back plate 231, and the plurality of slides 232 are spaced apart along the first direction x, and each slide 232 is provided with a corresponding cover plate 233. An opening 230 is formed between two adjacent pairs of slides 232 and cover plates 233. For example, see Figure 5-Figure 7 The quick-change device 20 includes four pairs of slides 232 and a cover plate 233. Three openings 230 are formed between the four pairs of slides 232 and the cover plate 233 for inserting the three mounting portions 201 of the battery 200. The three protrusions 211 of the locking member 21 can be driven by the driving unit to move from the slide groove to the openings 230 and thus inserted into the slots 202 of the mounting portion 201, or the three protrusions 211 of the locking member 21 can be driven by the driving unit to leave the slots 202 and hide in the slide groove.

[0097] 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 is used for inserting the mounting portion 201 of the battery 200 so that the protrusion 211 can be inserted into the slot 202 of the mounting portion 201, thereby realizing 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 portion 201 can share part of the space, which is conducive to improving the structural compactness of the vehicle 1000.

[0098] According to some embodiments of this application, see Figure 7 、 Figure 9 and Figure 10 , Figure 9 This is a schematic diagram of the first pushing portion 220, the base 23 and the locking member 21 in some embodiments of the present application. Figure 10 Schematic diagram of the second pushing portion 221 , the base 23 and the locking member 21 in some embodiments of the present application.

[0099] The driving member 22 includes a first pushing portion 220 and a second pushing portion 221. Along the first direction x, the first pushing portion 220 is arranged on one side of the main body 210, and the first pushing portion 220 is arranged on the other side of the main body 210. The first pushing portion 220 is used to push the main body 210 toward the second pushing portion 221, and the second pushing portion 221 is used to push the main body 210 toward the first pushing portion 220.

[0100] Along the first direction x, the first pushing portion 220 is disposed on one side of the locking member 21, and the second pushing portion 221 is disposed on the other side of the locking member 21. The first pushing portion 220 can provide a force to the locking member 21 in a direction directed from the first pushing portion 220 to the second pushing portion 221, and the second pushing portion 221 can provide a force to the locking member 21 in a direction directed from the second pushing portion 221 to the first pushing portion 220.

[0101] The first pushing part 220 is a driving mechanism capable of providing linear motion, including but not limited to a linear motor, a pneumatic rod, a hydraulic rod or other driving mechanisms. The second pushing part 221 is a driving mechanism capable of providing linear motion, including but not limited to a linear motor, a pneumatic rod, a hydraulic rod or other driving mechanisms.

[0102] Optionally, the actuating end of the first pushing portion 220 may or may not be connected to the locking member 21. For example, there is no connection between the first pushing portion 220 and the locking member 21, and when the first pushing portion 220 is in operation, it can push against the locking member 21 to push the locking member 21. Alternatively, the actuating end of the first pushing portion 220 is connected to the locking member 21, and the connection between the two includes, but is not limited to, bonding, welding, riveting, or threading. Optionally, the actuating end of the first pushing portion 220 and the locking member 21 can be fixed to each other or hinged to each other. The actuating end of the second pushing portion 221 may or may not be connected to the locking member 21. For example, there is no connection between the second pushing portion 221 and the locking member 21, and when the second pushing portion 221 is in operation, it can push against the locking member 21 to push the locking member 21. Alternatively, the actuating end of the second pushing portion 221 is connected to the locking member 21, and the connection between the two includes, but is not limited to, bonding, welding, riveting, or threading. Optionally, the execution end of the second pushing portion 221 and the locking member 21 may be fixed to each other or hinged to each other.

[0103] Optionally, the first pushing portion 220 and the second pushing portion 221 can push the locking member 21 to move along the first direction x by means of a high-pressure fluid. For example, the first pushing portion 220 provides the high-pressure fluid to the locking member 21 to move the locking member 21 toward the second pushing portion 221. The second pushing portion provides the high-pressure fluid to the locking member 21 to move the locking member 21 toward the first pushing portion 220.

[0104] For example, in combination Figure 5-Figure 7When the battery 200 is not mounted, the first pusher 220 operates to push the locking member 21 toward the second pusher 221, causing the protrusion 211 to be located in the slot and leaving the opening 230. When the battery 200 is mounted, the mounting portion 201 of the battery 200 is accommodated in the opening 230. The second pusher 221 operates to push the locking member 21 toward the first pusher 220, causing the protrusion 211 to move to the opening 230 and insert into the slot 202 of the mounting portion 201.

[0105] In some embodiments, when the first pushing portion 220 pushes the locking member 21 toward the second pushing portion 221, the second pushing portion 221 does not provide any pushing force, and the second pushing portion 221 allows the locking member 21 to move toward the second pushing portion 221. Similarly, when the second pushing portion 221 pushes the locking member 21 toward the first pushing portion 220, the first pushing portion 220 does not provide any pushing force, and the first pushing portion 220 allows the locking member 21 to move toward the first pushing portion 220.

[0106] Exemplarily, the first pushing part 220 and the second pushing part 221 each include a gas rod, and the air outlet of the first pushing part 220 is set in the slide groove and the air outlet is set toward the lock component 21. The air outlet of the second pushing part 221 is set in the slide groove and the air outlet is set toward the lock component 21.

[0107] When the battery 200 is not mounted, an external air source vents the first pusher 220, while the second pusher 221 is not vented or exhausted. The high-pressure gas provided by the first pusher 220 pushes the locking member 21 toward the second pusher 221. When the battery 200 is mounted, the mounting portion 201 of the battery 200 is accommodated in the opening 230. An external air source vents the second pusher 221, while the first pusher 220 is not vented or exhausted. The high-pressure gas provided by the second pusher 221 pushes the locking member 21 toward the first pusher 220, causing the protrusion 211 to move to the opening 230 and insert into the slot 202 of the mounting portion 201. The external air source is then closed, completing the securing of the battery 200. For example, a one-way valve may be provided between the second pusher 221 and the external air source so that when the external air source is closed, the second pusher 221 can maintain the current position of the locking member 21.

[0108] In the above solution, a first pushing portion 220 and a second pushing portion 221 are respectively provided on opposite sides of the locking member 21 along the first direction x to provide opposite thrusts to the locking member 21, thereby effectively switching the locking or unlocking relationship between the quick-change device 20 and the battery 200, thereby improving the assembly efficiency between the battery 200 and the vehicle body 100.

[0109] In other embodiments, the driving member 22 can be a mechanism that can provide linear reciprocating motion. The driving member 22 can be arranged on one side of the locking member 21 and connected to the locking member 21, and provide pushing and pulling forces to the locking member 21 so that the locking member 21 can move back and forth along the first direction x.

[0110] According to some embodiments of this application, see Figure 7 The first pushing portion 220 includes a first gas rod 2200 , and the second pushing portion 221 includes a second gas rod 2210 .

[0111] In some embodiments, the first gas rod 2200 can provide high-pressure gas directed from the first pushing portion 220 to the second pushing portion 221 to the locking member 21, so that the locking member 21 can move toward the second pushing portion 221. The second gas rod 2210 can provide high-pressure gas directed from the second pushing portion 221 to the first pushing portion 220 to the locking member 21, so that the locking member 21 can move toward the first pushing portion 220.

[0112] Optionally, the dimension of the chute along the first direction x is greater than the dimension of the locking member 21 along the first direction x, and the air outlet of the first gas rod 2200 and one end of the locking member 21 are both located in the chute, with the air outlet facing the locking member 21. The air outlet of the second gas rod 2210 and the other end of the locking member 21 are both located in the chute, with the air outlet facing the locking member 21.

[0113] See Figure 7 The first pushing portion 220 includes a first gas rod 2200, a first gas rod seat 2201, and a first joint 2202. The first gas rod 2200 is connected to the first gas rod seat 2201, which is connected to the base 23. The first joint 2202 is provided on the first gas rod seat 2201. The first joint 2202 is used to connect to an external gas source, which provides high-pressure gas to the first gas rod 2200 through the first joint 2202. The second pushing portion 221 includes a second gas rod 2210, a second gas rod seat 2211, and a second joint 2212. The second gas rod 2210 is connected to the second gas rod seat 2211, which is connected to the base 23. The second joint 2212 is provided on the second gas rod seat 2211. The second joint 2212 is used to connect to an external gas source, which provides high-pressure gas to the second gas rod 2210 through the second joint 2212.

[0114] In the above scheme, by arranging a first gas rod 2200 and a second gas rod 2210 on opposite sides of the locking member 21 along the first direction x, the locking member 21 is pushed to slide along the first direction x in a pneumatic manner, thereby effectively switching the locking or unlocking relationship between the quick-change device 20 and the battery 200, thereby improving the assembly efficiency between the battery 200 and the vehicle body 100.

[0115] According to some embodiments of this application, see Figure 7 、 Figure 9 and Figure 10 Along the first direction x, a first groove 2100 is formed on the end surface of the main body 210 that is away from the second pushing portion 221, and a second groove 2101 is formed on the end surface of the main body 210 that is away from the first pushing portion 220. The execution end of the first pushing portion 220 is arranged in the first groove 2100, and the execution end of the second pushing portion 221 is arranged in the second groove 2101.

[0116] In some embodiments, the body 210 is provided with a first groove 2100 and a second groove 2101 at two opposite ends along the first direction x, respectively. The first groove 2100 can accommodate at least a portion of the execution end of the first pushing portion 220 , and the second groove 2101 can accommodate at least a portion of the execution end of the second pushing portion 221 .

[0117] Optionally, the first pushing portion 220 includes a first gas rod 2200, the gas outlet of the first gas rod 2200 can be located in the first groove 2100, the first gas rod 2200 is slidably disposed in the first groove 2100, and a first sealing member 2203 is disposed between the outer circumference of the first gas rod 2200 and the inner circumference of the first groove 2100. An external gas source provides high-pressure gas to the first gas rod 2200, which enters the first groove 2100 and pushes the locking member 21. The second pushing portion 221 includes a second gas rod 2210, the gas outlet of the second gas rod 2210 can be located in the second groove 2101, the second gas rod 2210 is slidably disposed in the second groove 2101, and a second sealing member 2213 is disposed between the outer circumference of the second gas rod 2210 and the inner circumference of the second groove 2101. An external gas source provides high-pressure gas to the second gas rod 2210, which enters the second groove 2101 and pushes the locking member 21.

[0118] In the above scheme, by forming a first groove 2100 at one end of the main body 210 along the second direction y, which can accommodate the execution end of the first pushing part 220, and forming a second groove 2101 at the other end of the main body 210 along the second direction y, which can accommodate the execution end of the second pushing part 221, the space utilization rate of the driving part 22 and the locking part 21 can be improved, so that the quick-change device 20 has a compact structure, so that larger or more batteries 200 can be installed, which is beneficial to improve the cruising range of the vehicle 1000.

[0119] According to some embodiments of this application, see Figure 7 The quick-change device 20 further includes an elastic member 24 , which is disposed inside the base 23 and connected to the protrusion 211 .

[0120] The elastic member 24 is a structure with elastic characteristics. Exemplarily, the elastic member 24 includes a spring.

[0121] The elastic member 24 is disposed between the base 23 and the protrusion 211. The elastic member 24 can provide an elastic force along the first direction x to the protrusion 211. For example, the elastic member 24 is disposed in the slide groove, and a stopper is disposed in the second recess of the cover plate 233. One end of the elastic member 24 is connected to the stopper, and the other end of the elastic member 24 is used to abut against the side of the protrusion 211 facing away from the first pushing portion 220. This provides an elastic force from the second pushing portion 221 toward the first pushing portion 220 to the locking member 21, thereby tending to insert the protrusion 211 into the slot 202 of the mounting portion 201.

[0122] In some embodiments, the quick-change device 20 may include a plurality of elastic members 24 . For example, the number of the elastic members 24 may be two, and the two elastic members 24 are spaced apart along the first direction x.

[0123] In the above solution, by disposing the elastic member 24 inside the base 23, the stability of the locking member 21 can be improved, and the risk of the locking member 21 sliding due to external impact, which may make the battery 200 difficult to assemble or cause the battery 200 to be separated from the frame 10, can be reduced.

[0124] According to some embodiments of this application, see Figure 7 and Figure 11 , Figure 11 for Figure 9 An enlarged view of point A in the middle. An explosive member 25 is provided between the driving member 22 and the locking member 21 . The explosive member 25 is configured to push the locking member 21 to move along the first direction x by explosion, so that the locking member 21 is separated from the battery 200 .

[0125] The detonator 25 is a controllable explosion mechanism. For example, the detonator 25 can explode after receiving an execution instruction.

[0126] Optionally, the detonator 25 can be provided in the explosion mechanism between the first pushing portion 220 and the locking member 21. Figure 11The detonator 25 includes a detonator body 250 and a cable 251. The detonator body 250 is located in the first groove 2100 and is disposed on the outer circumference of the first gas rod 2200. The detonator body 250 may include a detonator head and a charge. The detonator head may include structures such as a spark plug and an electrode. The charge may be an explosive. Generally, the charge may include a mixture of substances such as sodium lead neonate, which can rapidly generate high-temperature and high-pressure gas. The wall of the first gas rod 2200 is formed with a perforation, and the cable 251 is routed through the perforation. One end of the cable 251 is connected to the detonator body 250, and the other end of the cable 251 is connected to the vehicle end. The vehicle end can send instructions to the detonator body 250 through the cable 251. For example, when the vehicle 1000 collides, the collision sensor sends a signal to the electronic control unit (ECU), and the electronic control unit (ECU) sends a signal to the detonator head. The spark plug of the detonator head generates an electric spark, igniting the explosive package. The explosive package quickly explodes to produce high-temperature and high-pressure gas, which pushes the locking component 21 to move.

[0127] In the above scheme, by arranging the detonating member 25 between the driving member 22 and the main body 210, in an emergency, the detonating member 25 can be triggered to push the locking member 21 to move in an explosive manner, thereby releasing the connection between the locking member 21 and the battery 200, so that the battery 200 can be quickly detached from the frame 10, reducing the probability of safety risks of the vehicle 1000 caused by loss of control of the battery 200, thereby making the driving reliability of the vehicle 1000 high.

[0128] According to some embodiments of the present application, the vehicle body 100 further includes an ejection member 30 , which is disposed on the vehicle frame 10 and is used to push the battery 200 along the gravity direction z.

[0129] One end of the ejection member 30 is connected to the vehicle frame 10 and is used to provide elastic force to the battery 200 along the gravity direction z. Optionally, the ejection member 30 may include a compressible and resilient device such as a metal spring, a gas spring, or an elastic colloid.

[0130] In the above solution, the ejection member 30 is provided to provide an elastic force toward the ground to the battery 200 . When the quick-change device 20 releases the lock on the battery 200 , the battery 200 can be quickly separated from the frame 10 under the action of the ejection member 30 .

[0131] According to some embodiments of this application, see Figure 4The vehicle frame 10 includes a connecting beam 11, a first cross beam 12, a second cross beam 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 cross beam 12 connects the first longitudinal beam 14 and the second longitudinal beam 15, and the second cross beam 13 connects the first longitudinal beam 14 and the second longitudinal beam 15. The first cross beam 12 and the second cross beam 13 are spaced apart.

Figure 3 and Figure 4 The two connecting beams 11 are spaced apart along the second direction y, and each connecting beam 11 is provided with two ejection members 30 .

[0135] In the above solution, by providing the connecting beam 11 and arranging the ejection member 30 on the connecting beam 11 , the ejection member 30 can provide a downward elastic force to the battery 200 above the battery 200 , thereby facilitating the battery 200 to be quickly separated from the frame 10 .

The positioning and mating portions 203 may include a positioning block and a positioning slot formed in the positioning block, and the positioning pin may be inserted into the positioning slot.

[0140] In the above solution, by providing a first positioning member 16 and a second positioning member for positioning the battery 200 on the lower surface of the frame 10, the battery 200 can be quickly assembled in the correct position under the action of the first positioning structure and the second positioning structure, so that the quick-change device 20 can quickly lock the battery 200, thereby effectively improving the assembly efficiency between the battery 200 and the vehicle body 100.

[0141] According to some embodiments of this application, see Figure 3 The frame 10 has a housing for accommodating a battery 200. A quick-change device 20 is provided on each side of the housing along the second direction y, for detachably connecting to opposite sides of the battery 200 along the second direction y. The first direction x, the second direction y, and the direction of gravity z are perpendicular to each other.

[0142] In some embodiments, the frame 10 has multiple quick-change devices 20, which are spaced apart along the second direction y to engage with both sides of the battery 200 along the second direction y. For example, one quick-change device 20 is provided on the inner side of the first longitudinal beam 14, and one quick-change device 20 is provided on the inner side of the second longitudinal beam 15.

[0143] In the above scheme, by arranging quick-change devices 20 on both sides of the accommodating cavity along the second direction y, so as to be detachably connected to the opposite sides of the battery 200 along the second direction y, the battery 200 can be evenly mounted on the frame 10 under force, so that the connection relationship between the battery 200 and the frame 10 is stable, which is beneficial to improving the driving reliability of the vehicle 1000.

[0144] The present application further provides a vehicle 1000 , which includes the vehicle body 100 provided above and a battery 200 . The battery 200 is detachably connected to the quick-change device 20 .

[0145] In the above scheme, the quick-change device 20 can enable the battery 200 to 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 replacement efficiency of the vehicle 1000 .

[0146] According to some embodiments of this application, see Figure 3 The battery 200 includes a box body, and a mounting portion 201 is provided on the outer side surface of the box body along the second direction y. The mounting portion 201 is formed with a slot 202 for inserting the locking member 21.

[0147] In the above scheme, by providing a mounting portion 201 on the box of the battery 200, the battery 200 can be effectively cooperated with the quick-change device 20, so that the battery 200 can be efficiently assembled on the vehicle body 100 or detached from the vehicle body 100, which is beneficial to improving the manufacturing efficiency of the vehicle 1000, or improving the battery replacement efficiency of the vehicle 1000.

[0148] According to some embodiments of this application, see Figure 2-Figure 11 , providing a vehicle body 100. The vehicle body 100 includes a frame 10 and a quick-change device 20, the quick-change device 20 is used to be detachably connected 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 replacement function.

[0149] Three mounting portions 201 are respectively formed on two opposite side surfaces of the battery 200 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 formed therein.

[0150] The vehicle frame 10 includes a connecting beam 11 , a first cross beam 12 , a second cross beam 13 , a first longitudinal beam 14 and a second longitudinal beam 15 .

[0151] The first longitudinal beam 14 and the second longitudinal beam 15 extend in a first direction x, and are arranged side by side in a second direction y. The first cross beam 12 and the second cross beam 13 are arranged between the first longitudinal beam 14 and the second longitudinal beam 15, and are spaced apart in the first direction x. The connecting beam 11 connects the first cross beam 12 and the second cross beam 13, and the two connecting beams 11 are spaced apart in the second direction y.

[0152] There are two quick-change devices 20 , one of which is disposed on the inner side of the first longitudinal beam 14 , and the other quick-change device 20 is disposed on the inner side of the second longitudinal beam 15 .

[0153] The quick-change device 20 includes a base 23 , a locking member 21 , a first pushing portion 220 , and a second pushing portion 221 .

[0154] The base 23 is formed with a slide groove and an opening 230, which communicates with the slide groove. The three openings 230 are spaced apart along the first direction x, and the mounting portion 201 of the battery 200 is inserted into the openings 230. The locking member 21 includes a body 210 and protrusions 211 disposed on the body 210. The three protrusions 211 are spaced apart along the first direction x. The locking member 21 is slidably disposed within the slide groove. A first pushing portion 220 and a second pushing portion 221 are respectively disposed on either side of the locking member 21 along the first direction x, and are used to push the locking member 21 along the first direction x, so that the protrusions 211 can move to the openings 230 for insertion into the slot 202 or exit the slot 202 to be accommodated within the slide groove.

[0155] The first pusher 220 includes a first gas rod 2200 for supplying high-pressure air to the locking member 21, causing it to move toward the second pusher 221, thereby allowing the protrusion 211 to exit the slot 202 and be accommodated within the guide groove. The second pusher 221 includes a second gas rod 2210 for supplying high-pressure air to the locking member 21, causing it to move toward the first pusher 220, thereby allowing the protrusion 211 to be inserted into the slot 202.

[0156] An explosive member 25 is provided between the first gas rod 2200 and the main body 210 of the locking member 21. The explosive member 25 is configured to push the locking member 21 toward the second pushing portion 221 by explosion, so that the protrusion 211 exits the slot 202 and the locking member 21 is detached from the battery 200.

[0157] An ejection member 30 is provided on one side of the connecting beam 11 facing the battery 200 . The ejection member 30 is used to provide an elastic force along the gravity direction z to the battery 200 .

[0158] In the above scheme, the vehicle body 100 is connected to the battery 200 through the quick-change device 20, and the locking part 21 can be moved in the first direction x by the driving part 22 to quickly lock the battery 200, or unlock the battery 200, thereby reducing the assembly difficulty between the battery 200 and the vehicle body 100 and improving the assembly efficiency. On the one hand, it can be beneficial to improve the manufacturing efficiency of the vehicle 1000, or to improve the battery replacement efficiency of the vehicle 1000. On the other hand, when the battery 200 is out of control, the connection relationship with the battery 200 can be quickly released by the driving part 22, so that the battery 200 can be quickly separated from the frame 10, thereby reducing the safety risk of the vehicle 1000 caused by the loss of control of the battery 200.

[0159] For example, through the technical solution provided above, the vehicle 1000 having the vehicle body 100 has the following effects:

[0160] 1. When the vehicle 1000 encounters an unavoidable emergency collision, if the system predicts in advance that the processing time is long, the vehicle end will cause the first gas rod 2200 to vent and the second gas rod 2210 to exhaust, the locking member 21 to move, and the protrusion 211 to exit the slot 202, thereby unlocking the battery 200. The battery 200 is ejected under the action of the ejection member 30, and the battery 200 is completely dropped.

[0161] Second, when the vehicle 1000 is directly hit by a serious collision, the safety airbag is triggered, the detonator 25 is triggered, and the detonator 25 is detonated, directly pushing the locking member 21 to slide, unlocking the battery 200, and the battery 200 is ejected under the action of the ejection member 30, completing the discarding of the battery 200.

[0162] Third, when the vehicle 1000 is hit by a hard collision at high speed, the locking member 21 can be forced to slide forward (toward the second pushing portion 221) under the action of the strong impact force and automatically unlock, providing a last insurance against detonation failure. The battery 200 is ejected by the ejection member 30, and the battery 200 is completely discarded.

[0163] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
