[0043] In order to connect the power assembly 2 with the suspension assembly 1, the power assembly 2 includes a power side bracket 21 and a connecting piece 22 connected to the power side bracket 21, the extension portion 12 is located above the power side bracket 21, and the connecting piece 22 can penetrate the extension portion 12 and the shell 13. Specifically, one end of the connecting piece 22 is connected to the power side bracket 21, and the other end of the connecting piece 22 extends upward through the extension portion 12 and the shell 13, and the axial direction of the connecting piece 22 is consistent with the height direction of the vehicle; the connecting structure 3 is arranged between the connecting piece 22 and the shell 13; wherein, when the vehicle is in a safe state, the connecting structure 3 locks the connecting piece 22 with the suspension assembly 1; when the vehicle is about to collide, the connecting structure 3 disengages the connecting piece 22 from the suspension assembly 1, that is, when the vehicle is in a safe state, the connecting structure 3 locks the connecting piece 22 with the shell 13; when the vehicle is about to collide, the connecting structure 3 disengages the connecting piece 22 from the shell 13. Therefore, in the vehicle provided in this embodiment, by setting the connection structure 3, when the vehicle is about to collide, the connection structure 3 can make the connection member 22 separate from the suspension assembly 1, that is, the power assembly 2 is separated from the suspension assembly 1.

By providing the connecting arms 14, when connecting the main body 11 and the vehicle body, the operator has a larger operating space, so that the assembly efficiency of the vehicle provided in this embodiment is higher.

[0047] As for the connection between the shell 13 and the extension part 12, an elastic connection can be adopted. Through the elastic connection, the force applied to the suspension assembly 1 can be buffered. For example, in the present embodiment, a buffer pad 15 made of rubber can be arranged between the bottom end of the shell 13 and the top surface of the extension part 12. Through the arrangement of the buffer pad 15, not only the force applied to the suspension assembly 1 can be buffered, but also the noise generated by shaking between the shell 13 and the extension part 12 can be reduced during the driving of the vehicle, so that the overall performance of the vehicle is improved.

[0048] It is understandable that the above-mentioned connecting member 22 can be a bolt with threads on the surface, or a connecting pin without threads on the surface. Here, the type of the connecting member 22 is not limited.

[0049] Therefore, the connecting piece 22 is made of metal, and the power side bracket 21 is also mostly made of metal or sheet metal.

Here, there is no specific limitation on the connection method between the connecting member 22 and the power side bracket 21.

[0051] Please continue to see Figure 5 , Figure 5 This is a schematic diagram of the structure of the housing body in the vehicle provided in an embodiment of the present application. Figure 6A schematic diagram of the structure of a cover plate in a vehicle provided in an embodiment of the present application. In some embodiments, the housing 13 includes a housing body 131 and a cover plate 132 buckled on the housing body 131, and a cavity 133 is formed between the cover plate 132 and the housing body 131, wherein the housing body 131 includes a first housing body 1311 and a second housing body 1312, and the cavity 133 includes a first inner cavity 1331 formed in the first housing body 1311 and a second inner cavity 1332 formed in the second housing body 1312, the first inner cavity 1331 and the second inner cavity 1332 are connected, the bottom end of the first housing body 1311 is connected to the extension portion 12 through the buffer pad 15, the top end of the first housing body 1311 extends upward, and the connector 22 passes through the first inner cavity 1331, the second housing body 1312 is connected to the side of the first housing body 1311, and the cover plate 132 buckles and covers the end of the second housing body 1312 away from the first housing body 1311.

[0052] In some embodiments, in order to improve the cushioning performance of the cushion 15, the contact area between the cushion 15 and the bottom end of the first shell body 1311 can be increased, so that the outer edge 1313 can be connected to the outside of the bottom end of the first shell body 1311, the outer edge 1313 is a ring-shaped member, and the inner peripheral wall of the outer edge 1313 is connected to the outer peripheral surface of the first shell body 1311. In this way, the projection area of ​​the bottom end of the first shell body 1311 on the cushion 15 is enlarged, so that the contact area between the first shell body 1311 and the cushion 15 is larger, so that the cushioning performance of the cushion 15 is better.

[0053] In this embodiment, in order to maintain good cushioning performance of the cushion pad 15 while reducing the manufacturing cost of the cushion pad 15 , the contour shape of the cushion pad 15 is adapted to the contour shape of the outer edge portion 1313 .

[0054] Specifically, the cover plate 132 includes a first plate body 1321 located outside and a second plate body 1322 connected to the first plate body 1321, wherein the contour shape of the first plate body 1321 is adapted to the contour shape of the second shell body 1312, the contour shape of the second plate body 1322 is adapted to the contour shape of the second inner cavity 1332, and the second plate body 1322 extends into the second inner cavity 1332 and is connected to the second shell body 1312. It should be noted that the second plate body 1322 and the second shell body 1312 can be connected in a detachable manner such as a threaded connection or a snap connection, and the second plate body 1322 and the second shell body 1312 can also be connected in a manner such as bonding or welding, and here, the connection method between the second plate body 1322 and the second shell body 1312 is not limited.

[0055] Please continue to see Figures 7 to 9 , Figure 7for Figure 2 Schematic diagram of the structure along direction B, Figure 8 for Figure 7 Cross-sectional view along CC direction, Fig. 9 for Figure 8 The enlarged schematic diagram of the local structure at D in the figure. In order for the connection structure 3 to connect the connector 22 to the shell 13 when the vehicle is in a safe state, and to separate the connector 22 from the shell 13 when the vehicle is in a state of collision, in some embodiments, the connection structure 3 may include a drive assembly 31 and a locking member 32, the drive assembly 31 is arranged between the shell 13 and the locking member 32, and the locking member 32 is slidably matched with the inner cavity of the shell 13, specifically, the drive assembly 31 is arranged between the cover plate 132 and the locking member 32, and the locking member 32 is slidably matched with the side wall of the second inner cavity 1332; wherein, when the vehicle is in a safe state, the locking member 32 is connected with the connector 22 to lock the connector 22 to the shell 13; when the vehicle is about to collide, the locking member 32 moves away from the connector 22 and disengages from the connector 22 to separate the connector 22 from the shell 13.

[0056] Please continue to see Fig.10 and Fig.11 , Fig.10 for Figure 7 Cross-sectional view along EE direction, Fig.11 for Fig.10 The enlarged schematic diagram of the local structure at F in the middle. Specifically, the above-mentioned locking member 32 can be a slider, and a locking groove 221 is provided on the side wall of the connecting member 22; when the vehicle is in a safe state, at least part of the structure of the locking member 32 extends into the locking groove 221 to lock the connecting member 22 and the housing 13 together, that is, the connecting member 22 and the housing body 131 are connected together. It can be understood that when at least part of the structure of the locking member 32 extends into the locking groove 221, the relative position between the connecting member 22 and the housing 13 is fixed in the axial direction of the connecting member 22, that is, in the up and down directions, the relative position of the power assembly 2 and the suspension assembly 1 is fixed.

[0057] In order to avoid relative rotation between the connecting member 22 and the housing 13 to a certain extent when the vehicle is in a safe state, the relative position of the power assembly 2 and the suspension assembly 1 can be fixed in the radial direction of the connecting member 22, that is, the relative position between the connecting member 22 and the housing 13 can be fixed in the radial direction of the connecting member 22, and the above-mentioned locking groove 221 extends along the circumferential direction of the connecting member 22; and the locking member 32 has a mating surface 321 adapted to the bottom of the locking groove 221.

[0058] The locking groove 221 is an annular groove, and on the same cross section, the center of the locking groove 221 coincides with the center of the connecting member 22, and the central angle of the bottom wall of the locking groove 221 is 90 degrees. In order to fix the relative position between the connecting member 22 and the housing 13 in the radial direction of the connecting member 22, the matching surface 321 covers at least three-quarters of the bottom of the locking groove 221 in the extension direction of the bottom wall of the locking groove 221 when the vehicle is in a safe state, and the two ends of the matching surface 321 in the extension direction of the bottom wall of the locking groove 221 are symmetrically arranged about the central axis of the connecting member 22. In this way, when the vehicle is in a safe state, the connecting structure 3 can reliably connect the suspension assembly 1 and the power assembly 2 together.

[0059] In this embodiment, the longitudinal section of the second inner cavity 1332 is rectangular, and each side wall of the locking member 32 is slidably matched with the corresponding side wall of the second inner cavity 1332 .

[0060] Please continue to see Figure 12 to Figure 14 , Fig.12 for Figure 2 Schematic diagram of the structure along the G direction, Fig.13 for Fig.12 Cross-sectional view along the HH direction, Fig.14 for Fig.13 The enlarged schematic diagram of the local structure at I in the middle. In order for the driving assembly 31 to drive the locking member 32 to move in a direction away from the connecting member 22 when the vehicle is in a state of collision, in some embodiments, the driving assembly 31 includes an elastic connecting member 311 and a driving member 312; the elastic connecting member 311 is arranged between the housing 13 and the locking member 32, and the elastic force of the elastic connecting member 311 is used to drive the locking member 32 to move in a direction close to the connecting member 22 when the vehicle is in a safe state, specifically, the elastic connecting member 311 is connected between the second plate 1322 and the locking member 32; the driving member 312 is connected to the housing 13, and the driving member 312 is used to apply a driving force to the locking member 32 when the vehicle is about to collide, so as to drive the locking member 32 to move in a direction away from the connecting member 22. In this way, when the vehicle is in a safe state, under the elastic force of the elastic connector 311, the locking member 32 and the connecting member 22 are reliably matched, so that the suspension assembly 1 and the power assembly 2 are reliably connected; when the vehicle is about to collide, the driving member 312 can drive the locking member 32 to move away from the connecting member 22, so that the locking member 32 is separated from the connecting member 22, and the power assembly 2 moves downward under the action of gravity to disconnect from the suspension assembly 1, thereby preventing the power assembly 2 from invading the passenger compartment to a certain extent.

[0061] The elastic connecting member 311 may be a spring, or other elastic structural member, such as a rubber member. The type of the elastic connecting member 311 is not specifically limited.

[0062] In a specific implementation of this embodiment, the elastic connecting member 311 is a spring, and in order to improve the stability of the spring, a positioning groove 322 can be provided on the locking member 32, one end of the spring is located in the positioning groove 322 and connected to the inner wall of the positioning groove 322, and the other end is connected to the second plate 1322. In this way, the stability of the spring can be improved, so that when the vehicle is in a safe state, the elastic force applied by the spring to the locking member 32 is relatively stable, thereby making the connection between the suspension assembly 1 and the power assembly 2 more reliable.

[0063] In a specific embodiment, the driving member 312 can be an electromagnet; the electromagnet is located on the side of the locking member 32 away from the connecting member 22, and is connected to the second plate 1322 on the shell 13, and the electromagnet is electrically connected to the control module on the vehicle. In order to enable the coil on the electromagnet to be electrically connected to the external control module, a wire hole 1323 can pass through the cover plate 132, and the wire hole 1323 also passes through the first plate 1321 and the second plate 1322; the control module is used to supply power to the electromagnet when the vehicle is about to collide, so that the electromagnet generates a magnetic force on the locking member 32, driving the locking member 32 to move in a direction away from the connecting member 22.

[0064] It should be noted that the control module can be an electronic control unit (ECU), i.e., an onboard computer, or a separate control module disposed inside the vehicle. The specific form of the control module is not limited here.

[0065] Furthermore, the control module has a monitoring function, and when the control module detects that the vehicle is about to collide, it will supply power to the electromagnet. Here, the logic of this process will not be described in detail.

[0066] When the vehicle is about to collide, in order to enable the locking member 32 to quickly withdraw from the locking groove 221, a force can be applied to the locking member 32 away from the connecting member 22 to prompt it to quickly withdraw from the locking groove 221, and the resistance encountered by the locking member 32 in the process of withdrawing from the locking groove 221 can also be reduced.

[0067] Therefore, for the former method of applying a force to the locking member 32 in a direction away from the connecting member 22, the top surface of the locking member 32 can extend from bottom to top in a direction from close to the connecting member 22 to away from the connecting member 22, and the angle between the top surface and the horizontal plane is greater than 0 degrees and less than or equal to 30 degrees. In this way, the gravity of the power assembly 2 will exert a component force on the locking member 32, prompting the locking member 32 to move in a direction away from the connecting member 22, so that the locking member 32 can quickly withdraw from the locking groove 221, thereby improving the disengagement efficiency of the suspension assembly 1 and the power assembly 2.

[0068] The angle between the top surface and the horizontal plane may be 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, etc. Here, there is no limitation on the angle between the top surface and the horizontal plane.

[0069] For the latter, in order to reduce the resistance of the locking member 32 during the withdrawal process, the friction between the locking member 32 and the wall of the second inner cavity 1332 can be reduced, thereby, see Fig.15 and Fig.16 , Fig.15 A schematic diagram of the structure of a locking member in a vehicle provided in an embodiment of the present application, Fig.16 for Fig.15 A schematic diagram of the partial structure at J in the middle is enlarged. A lubrication groove 323 for storing lubricating oil can be provided on the top surface of the locking member 32. By providing the lubrication groove 323 and filling the lubricating oil inside, the friction between the locking member 32 and the side wall of the second inner cavity 1332 can be reduced, so that the resistance encountered by the locking member 32 during the withdrawal process is small, thereby increasing the withdrawal speed of the locking member 32.

[0070] It should be noted that if a lubrication groove 323 is opened on the bottom surface or the side surfaces of the locking piece 32, the internal lubricating oil will flow downward under the action of gravity, making it impossible for the lubricating oil to perform its own function. Therefore, in this embodiment, the lubrication groove 323 is opened on the top surface of the locking piece 32.

[0071] In this embodiment, the extension direction of the lubrication groove 323 is consistent with the moving direction of the locking member 32. In some other embodiments, the lubrication groove 323 may also extend in other directions, and the extension direction of the lubrication groove 323 is not limited.

[0072] In order to further reduce the friction between the locking member 32 and the side wall of the second inner cavity 1332, a plurality of lubrication grooves 323 may be provided on the top surface of the locking member 32, and the plurality of lubrication grooves 323 are arranged at intervals. Here, the number of the lubrication grooves 323 is not limited.

[0073] In some other embodiments, multiple connecting members 22 and multiple connecting structures 3 may be provided to reduce the resistance of the locking member 32 when it exits the corresponding locking groove 221, wherein one connecting structure 3 corresponds to one connecting member 22. In this way, when the structures of the suspension assembly 1 and the power assembly 2 are fixed, when multiple connecting members 22 are provided, the electromagnetic force generated by each electromagnet is smaller, and the resistance of each locking member 32 when it exits the locking groove 221 is smaller, so that each locking member 32 can quickly exit from the locking groove 221 when the vehicle is about to collide.

[0074] The number of the above-mentioned connecting members 22 and connecting structures 3 can be between 2 and 8. It should be noted that when there are multiple connecting members 22, there should also be multiple housings 13, and they should be arranged one by one corresponding to the connecting members 22. Here, there is no specific limitation on the number of connecting members 22 and connecting structures 3.
