Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and more particularly, to a new energy vehicle and an assembly method thereof. Background Art

[0002] Currently, large-capacity batteries are generally used as the power source in the field of new energy vehicles. To meet the endurance requirement, the batteries are usually arranged in the vehicle chassis area and connected to the vehicle body structure through the fixing brackets on the batteries. The battery cells inside the battery are usually square or cylindrical, and the battery cells are arranged in a regular arrangement, and then the battery cells are wrapped by a box assembly to form a battery. The space for the vehicle to install the battery needs to be reserved according to the size of the battery cells and the protection requirements. Some solutions improve the capacity by horizontally expanding the layout, but such designs often require synchronous adjustment of the vehicle chassis structure.

[0003] When pursuing large capacity, the battery layout method is likely to cause an increase in the vehicle width, thus affecting the vehicle handling stability and the passenger space. Therefore, the space of the vehicle beam is utilized to arrange the battery at the bottom of the vehicle beam. However, when connecting the vehicle beam and the battery, connection components need to be added in the width direction of the vehicle between the battery and the beam to ensure the stability of the battery and the vehicle beam, resulting in a further increase in the width of the vehicle for installing the battery.

[0025] If the spacing between the first frame unit and the beam along the width direction of the beam and the size of the locking unit along the width direction of the beam are set to be equal, in the actual assembly process, due to processing tolerances, the width of the first energy storage component may be greater than the spacing between the beams, and thus it cannot be installed in the gap between the fixed units by hoisting or lifting. Therefore, it is necessary to have a certain gap between the beam and the first frame unit to allow the first energy storage component and the fixed component to be installed. Therefore, this scheme allows S1<S2, so that the projection of the locking unit toward the beam is located below the two beams and the beam spacing area. In this way, the beam and the fixed unit are directly set to be spaced from the first energy storage unit, and then the first frame unit and the fixed unit are connected through the locking unit. This not only ensures that the first energy storage component can be installed in the gap between the fixed units by hoisting or lifting, but also can guarantee the vehicle's endurance as much as possible.

[0043] In this embodiment, in the structure of a new energy vehicle, the battery is usually arranged inside the vehicle body or in the chassis area, and there are problems such as limited installation space. In the prior art, it is necessary to add a connection component between the battery and the girder 11 in the width direction of the vehicle, which is difficult to achieve a compact fit between the battery and the vehicle body girder 11, resulting in low space utilization. Therefore, to solve the above problems, the present invention provides a new energy vehicle, as Figure 1 、 Figure 2 shown, the new energy vehicle may include a vehicle component 01, a fixing component 02, a first energy storage component 03, and a second energy storage component 04.

[0044] The vehicle component 01 may include two girders 11 and a connecting beam 12. The two girders 11 may be arranged at intervals in the width direction of the girders 11. One end of the connecting beam 12 may be connected to one girder 11, and the other end may be connected to the other girder 11, thereby forming a stable structure.

[0045] As Figure 4 , Figure 6 shown, the fixing component 02 may include a fixing unit 21 and a locking unit 22. One end of the fixing unit 21 may be connected to the girder 11, and the other end may extend along the height direction of the girder 11. The girder 11 may achieve a firm connection between the girder 11 and the first energy storage component 03 and the second energy storage component 04 through the fixing component 02.

[0046] The first energy storage component 03 may include a first energy storage unit 31 and a first frame unit 32. A part of the first energy storage unit 31 may be disposed in the space surrounded by the first frame unit 32. The width of the first frame unit 32 may be less than or equal to the shortest distance between the two main beams 11. The ratio of the width of the first energy storage unit 31 to the shortest distance between the two main beams 11 is less than or equal to 1 and greater than 0.95. This facilitates moving the first energy storage component 03 from above the gap between the two main beams 11 to the gap between the two fixing units 21, and then connecting the first energy storage component 03 to the fixing unit 21 through the locking unit 22, that is, hoisting. Or moving the first energy storage component 03 from below the gap between the two main beams 11 to between the two main beams 11, and then connecting the first energy storage component 03 to the fixing unit 21 through the locking unit 22, that is, lifting. Thus, the first energy storage unit 31 can occupy as much space between the two main beams 11 as possible, ensuring that the first energy storage unit 31 can provide more cruising range for the vehicle. One fixing unit 21, the first energy storage component 03, and the other fixing unit 21 may be sequentially arranged along the width direction of the first energy storage component 03. One end of the locking unit 22 may be detachably connected to the first frame unit 32, and the other end may be detachably connected to the fixing unit 21. If the distance between the first frame unit 32 and the main beam 11 along the width direction of the main beam 11 is set to be equal to the dimension of the locking unit 22 along the width direction of the main beam 11, during the actual assembly process, due to machining tolerances, the width of the first energy storage component 03 may be greater than the distance between the main beams 11, resulting in the inability to install it into the gap between the fixing units 21 by hoisting or lifting. Therefore, there needs to be a certain gap between the main beam 11 and the first frame unit 32 to enable the installation of the first energy storage component 03 and the fixing component 02. Thus, in this solution, S1 < S2, where S1 is the distance between the first frame unit 32 and the main beam 11 along the width direction of the main beam 11, and S2 is the dimension of the locking unit 22 along the width direction of the main beam 11, such that the projection of the locking unit 22 towards the main beam 11 is located below the two main beams 11 and the interval area between the main beams 11. In this way, the main beam 11 and the fixing unit 21 are directly spaced from the first energy storage unit 31, and then the first frame unit 32 and the fixing unit 21 are connected through the locking unit 22. This can not only ensure that the first energy storage component 03 can be installed into the gap between the fixing units 21 by hoisting or lifting, but also maximize the cruising ability of the first energy storage unit 31 for the vehicle.

[0047] The second energy storage component 04 can be detachably connected to the side of the locking unit 22 away from the first energy storage component 03. In this way, by adding the second energy storage component 04, the endurance of the vehicle can be further improved. When the first energy storage component 03 and the second energy storage component 04 are respectively installed on the crossbeam 11, the projections of the first energy storage component 03 and the second energy storage component 04 along the height direction of the first energy storage component 03 are spaced from the crossbeam 11 and the connecting beam 12, so as to avoid interference between the first energy storage component 03 and the second energy storage component 04 when they are respectively connected to the crossbeam 11.

[0048] In this embodiment, as Figure 3 shown, the first frame unit 32 may include a first frame 321, a second frame 322, and a first support rod 323. The first frame 321 and the second frame 322 may be spaced along the height direction of the first frame 321. One end of the first support rod 323 may be connected to the first frame 321, and the other end may be connected to the second frame 322. The first frame 321 and / or the second frame 322 and / or the first support rod 323 are connected to the first energy storage unit 31. The widths of the first frame 321 and the second frame 322 may be respectively less than or equal to the shortest distance between the two crossbeams 11, which is convenient for moving the first frame 321 and the second frame 322 from the gap between the two crossbeams 11 to the gap between the two fixing units 21, and then realizing the connection between the first frame 321, the second frame 322 and the fixing unit 21 through the locking unit 22, that is, hoisting or lifting. Thus, the first frame unit 32 can occupy as much space between the two crossbeams 11 as possible, ensuring that the first energy storage unit 31 can provide more driving range for the vehicle.

[0049] When the vehicle is stationary, the strength of the first support rod 323 is sufficient to ensure the connection between the first energy storage component 03 and the fixing unit 21. However, during the driving process of the vehicle, the vehicle will vibrate continuously, and the strength of the first support rod 323 is insufficient, which is likely to cause deformation of the frame structure of the first frame unit 32, and ultimately damage the first energy storage unit 31. Therefore, the locking unit 22 is provided in this solution, as Figure 2As shown, the locking unit 22 may include a first locking rod 221, a second locking rod 222, and a third locking rod 223. The first locking rod 221, the second locking rod 222, and the third locking rod 223 may be connected in sequence. The second locking rod 222 may be detachably connected to the fixing unit 21. One end of the first locking rod 221 away from the second locking rod 222 extends toward the first frame 321 to be detachably connected to the first frame 321. One end of the third locking rod 223 away from the second locking rod 222 extends toward the second frame 322 to be detachably connected to the second frame 322. In this way, while the first energy storage component 03 can be fixed by the locking unit 22, it can also act as a reinforcing bar between the first frame 321 and the second frame 322, thereby effectively suppressing the deformation of the first frame unit 32 caused by vehicle vibration.

[0050] In some other embodiments, as Figure 8 shown, the second frame unit 42 may include a third frame 421, a fourth frame 422, and a second support rod 423. The third frame 421 and the fourth frame 422 are arranged at intervals along the height direction of the third frame 421. One end of the second support rod 423 may be connected to the third frame 421, and the other end may be connected to the fourth frame 422. The third frame 421 and / or the fourth frame 422 and / or the second support rod 423 are connected to the second energy storage unit 41. The second frame unit 42 can protect the second energy storage unit 41 and connect the second energy storage unit 41 to the fixing unit 21 through the second frame unit 42 to provide energy for the vehicle.

[0051] In some other embodiments, as Figure 4 shown, when lifting or hoisting the first energy storage component 03, it is necessary to make the bolt pass through the first frame unit 32 and the locking unit 22 so that the first frame unit 32 and the locking unit 22 are locked. However, due to the possible offset between the position of the first energy storage component 03 and the position of the fixing unit 21, the bolt cannot connect the first energy storage component 03 and the fixing unit 21 through the locking unit 22. Therefore, an oblong hole is adopted at the connection between the locking unit 22 and the fixing unit 21 of this solution. The length direction of the oblong hole is arranged along the width direction of the vehicle. Through the oblong hole, the distance between the fixing unit 21 and the first energy storage component 03 can be adapted to avoid the offset between the fixing unit 21 and the first energy storage component 03, resulting in the bolt being unable to pass through the first frame unit 32 and the locking unit 22 in sequence.

[0052] In this embodiment, as Figure 7 、 Figure 11As shown, the fixing unit 21 may include a fixing body 211, a first connection module 212, a second connection module 213, and a connecting rod 214. The fixing body 211 may be detachably connected to the girder 11. The first connection module 212 may be made of a flexible material. The first connection module 212 may be connected to the fixing body 211. One end of the connecting rod 214 may be connected to the first connection module 212, and the other end may extend towards the first energy storage unit 31. When the girder 11 is twisted and deformed, the first connection module 212 absorbs most of the stress through its own deformation, preventing the deformation generated when the girder 11 is twisted from being transmitted to the first energy storage unit 31 and causing damage to the first energy storage unit 31. One end of the locking unit 22 may be detachably connected to the connecting rod 214, and the other end may be detachably connected to the first energy storage assembly 03. One connecting rod 214, the first energy storage assembly 03, and the other connecting rod 214 are arranged in sequence along the width direction of the first energy storage assembly 03. One end of the second connection module 213 is connected to the connecting rod 214, and the other end is detachably connected to the second energy storage assembly 04, thus facilitating the efficient installation among the fixing body 211, the first connection module 212, the second connection module 213, and the connecting rod 214.

[0053] In some other embodiments, the fixing unit 21 may further include a bearing rod 215. One end of the bearing rod 215 is detachably connected to the end of the connecting rod 214 away from the fixing body 211, and the other end is detachably connected to the end of the other connecting rod 214 away from the fixing body 211. The bearing rod 215 may abut against and / or be detachably connected to the lower end surface of the first energy storage part 311. When hoisting the first energy storage unit 31, it is necessary to first connect the bearing rod 215 and the connecting rod 214, and then hoist the first energy storage unit 31. When lifting the first energy storage unit 31, first connect the bearing rod 215 to the first energy storage assembly 03, and then lift them together into the gap of the girder 11. Thus, the bearing rod 215 can bear the gravity load of the first energy storage assembly 03 and further strengthen the stability of the first energy storage assembly 03.

[0054] In this embodiment, as Figure 12 , Figure 13As shown, the first connection module 212 may include a first buffer ring 2121 and a first mounting portion 2122. The first buffer ring 2121 may be made of a flexible material, so that most of the stress can be absorbed through the self-deformation of the first buffer ring 2121, avoiding the deformation generated when the girder 11 is distorted from being transmitted to the first energy storage unit 31. The first mounting portion 2122 may be made of a rigid material. The first mounting portion 2122 may be connected to the fixed body 211, so that the first mounting portion 2122 made of a rigid material is connected to the fixed body 211, ensuring that the relative positions of the first mounting portion 2122 and the fixed body 211 will not shift. The inner peripheral wall of the first buffer ring 2121 may be connected to the outer peripheral wall of the first mounting portion 2122. The minimum included angle between the axial direction of the first mounting portion 2122 and the height direction of the girder 11 is 25° to 90°. One end of the connecting rod 214 close to the girder 11 is detachably connected to the outer peripheral wall of the first buffer ring 2121. During the driving of the vehicle, vibrations will occur. The first energy storage assembly 03 exerts a downward force on the first buffer ring 2121 through the connecting rod 214, avoiding excessive axial force on the first buffer ring 2121, which may cause the first buffer ring 2121 and the first mounting portion 2122 to relatively slide axially along the first buffer ring 2121 until the first buffer ring 2121 and the first mounting portion 2122 are spaced apart. Thus, the force received by the first buffer ring 2121 can be converted into the compression deformation of the first buffer ring 2121, improving the anti-pull-off ability of the first connection module 212.

[0055] In this embodiment, as Figure 6 shown, since the first energy storage assembly 03 will sway in the vehicle body width direction during the driving of the vehicle, causing the girder 11 to deform, the axial direction of the first mounting portion 2122 is set parallel to the length direction of the girder 11. The length direction of the girder 11 is Figure 11 the left-right direction shown, so that the vibrations and swaying of the vehicle apply forces axially to the first buffer ring 2121, making it difficult for the first buffer ring 2121 and the first mounting portion 2122 to separate. The radial thickness of the first buffer ring 2121 can be fully utilized to absorb vibrations and deformation amounts, avoiding the deformation and impact of the girder 11 from being transmitted to the first energy storage assembly 03.

[0056] In this embodiment, as Figure 10 、 Figure 12 shown, the first buffer ring 2121 can allow relative displacement between the first energy storage assembly 03 and the girder 11. However, if the relative displacement between the first energy storage assembly 03 and the girder 11 is too large during the driving of the vehicle, it will cause too large a change in the center of gravity of the vehicle, making the vehicle difficult to control. Therefore, the end of the second connection module 213 away from the connecting rod 214 is flexibly connected to the fixed body 211, so that the relative displacement amount between the first energy storage unit 31 and the girder 11 is limited through the flexible connection of the second connection module 213, enabling the vehicle to drive on the road surface more smoothly.

[0057] In this embodiment, as Figure 5 , Figure 6 shown, the second connection module 213 may include a second buffer ring 2131 and a side hanging portion 2132. The outer peripheral surface of the second buffer ring 2131 may be connected to the fixed body 211. The inner peripheral surface of the second buffer ring 2131 may be connected to the side hanging portion 2132. One end of the side hanging portion 2132 away from the second buffer ring 2131 is connected to the connecting rod 214. The axial direction of the second buffer ring 2131 is parallel to the height direction of the crossbeam 11. The second buffer ring 2131 can better limit the movement amount of the side hanging portion 2132 along the radial direction of the second buffer ring 2131, so as to cooperate with the first buffer ring 2121, enabling the first energy storage assembly 03 to have a relative displacement with the crossbeam 11, and the displacement amount is controlled within a reasonable range. The second energy storage assembly 04 is detachably connected to the side hanging portion 2132. Thus, it can not only ensure the smoothness of the vehicle during driving, but also prevent the load of the crossbeam 11 from being transmitted to the first energy storage unit 31 and causing damage to the first energy storage unit 31.

[0058] In this embodiment, as Figure 3 , Figure 6 shown, the second connection module 213 may further include a hook 2133, a side hanging hole 2134, and a side hanging groove 2135. One end of the hook 2133 may be connected to the side hanging portion 2132, and the other end may extend towards the direction close to the first energy storage assembly 03. The hook 2133 can bear the vertical downward gravity load of the second energy storage assembly 04. The side hanging hole 2134 and the side hanging groove 2135 may respectively penetrate through both sides of the side hanging portion 2132 along the width direction of the crossbeam 11. The side hanging hole 2134 may communicate with the side hanging groove 2135. The radial direction of the side hanging hole 2134 may coincide with the length direction of the side hanging groove 2135, and the length direction of the side hanging groove 2135 is Figure 7 the up and down direction shown. The side hanging groove 2135 is arranged below the side hanging hole 2134, and the aperture of the side hanging hole 2134 is larger than the groove width of the side hanging groove 2135.

[0059] As Figure 8 , Figure 9As shown, the second energy storage component 04 may include a second energy storage unit 41, a second frame unit 42, and a suspension unit 43. The second energy storage unit 41 may be connected to the second frame unit 42. Part of the second energy storage unit 41 may be disposed within the space surrounded by the second frame unit 42. The suspension unit 43 may include a suspension body 431, an extension rod 432, and a clamping portion 433. The suspension body 431 may be connected to the second frame unit 42. One end of the extension rod 432 may be connected to the suspension body 431, and the other end may extend toward the side hanging portion 2132. The clamping portion 433 may be connected to one end of the suspension body 431 close to the side hanging portion 2132. The diameter of the clamping portion 433 is smaller than the aperture of the side hanging hole 2134 and larger than the groove width of the side hanging groove 2135. The diameter of the extension rod 432 is smaller than the groove width of the side hanging groove 2135. The hook 2133, the second frame unit 42, and the suspension body 431 are sequentially abutted and arranged along the direction from the bottom end to the top end of the girder 11. Bolts sequentially pass through the hook 2133, the second frame unit 42, and the suspension body 431, so that the second frame unit 42 is detachably connected to the hook 2133 and the suspension body 431 respectively, thereby restricting the relative position of the second storage component and the fixing unit 21 in this way. When the second energy storage component 04 moves to be connected to the fixing component 02, the clamping portion 433 is moved into the interior of the side hanging hole 2134 along the direction from the side hanging hole 2134 to the first energy storage component 03, and then slides downward along the side hanging groove 2135 into the side hanging groove 2135. The diameter of the clamping portion 433 being smaller than the aperture of the side hanging hole 2134 and larger than the groove width of the side hanging groove 2135 can prevent detachment, facilitating the bolts to sequentially pass through the hook 2133, the second frame unit 42, and the suspension body 431, and then locking the second storage component.

[0060] In some other embodiments, the second energy storage unit 41 may include a third energy storage portion 411 and a fourth energy storage portion 412. The third frame 421 and / or the fourth frame 422 and / or the second support rod 423 are connected to the third energy storage portion 411. The third frame 421 is disposed on the side of the fourth frame 422 close to the girder 11. The fourth energy storage portion 412 is connected to the second frame 322. The third energy storage portion 411 is disposed within the space surrounded by the second frame unit 42. Through the third energy storage portion 411 and the fourth energy storage portion 412, more energy can be provided for the vehicle, increasing the endurance of the vehicle.

[0061] The vehicle component 01 may further include a driving unit, and the driving unit may be a wheel, so as to ensure that the vehicle can drive normally on the road surface through the driving unit.

[0062] In this embodiment, as Figure 2As shown, the first energy storage unit 31 may include a first energy storage part 311 and a second energy storage part 312. The first frame 321 and / or the second frame 322 and / or the first support rod 323 are connected to the first energy storage part 311. The first frame 321 may be disposed on a side of the second frame 322 close to the girder 11. The second energy storage part 312 is connected to the first frame 321. The first energy storage part 311 is disposed within the space surrounded by the first frame unit 32. The ratio of the width of the first energy storage part 311 to the shortest distance between the two girders 11 is less than or equal to 1 and greater than 0.95. The ratio of the width of the second energy storage part 312 to the shortest distance between the two girders 11 is less than or equal to 1 and greater than 0.95. In this way, the first energy storage unit 31 can make full use of the space between the two girders 11 to increase the vehicle's cruising range and can also avoid... At least a part of the second energy storage part 312 is disposed within the space between the two girders 11, and the second energy storage part 312 can further increase the vehicle's cruising range.

[0063] In this embodiment, the present invention provides an assembly method, which can be applied to any one of the new energy vehicles in the above embodiments, such as Figure 14 As shown, the assembly method may include steps S10 to S30.

[0064] Step S10, based on the preliminary assembly being completed, the first energy storage assembly 03 can be moved between the two fixing units 21. Among them, the preliminary assembly being completed includes that the two girders 11 are arranged at intervals along the width direction of the girder 11, one end of the connecting beam 12 is connected to one girder 11, the other end is connected to the other girder 11, one end of the fixing unit 21 is connected to the girder 11, and the other end extends along the height direction of the girder 11. The girder 11 provides the basic framework of the vehicle and can be used to carry and assemble the first energy storage assembly 03 and the second energy storage assembly 04.

[0065] Step S20, if the first energy storage assembly 03 is installed in a lifting manner, the carrier rod 215 needs to be disassembled first, then the first energy storage assembly 03 is moved between the two fixing units 21, and then one end of the locking unit 22 is connected to the first energy storage assembly 03 and the other end of the locking unit 22 is connected to the fixing unit 21. The locking unit 22 can not only fix the first energy storage assembly 03, but also act as a reinforcing rod between the first frame 321 and the second frame 322, thereby effectively suppressing the torsional deformation of the first frame unit 32 caused by vehicle vibration.

[0066] Step S30: Based on connecting one end of the locking unit 22 to the first energy storage component 03 and connecting the other end of the locking unit 22 to the fixing unit 21, connect the second energy storage component 04 to the side of the fixing unit 21 away from the first energy storage component 03. When installing the second energy storage component 04, move the engaging portion 433 into the inner side hanging hole 2134, and then slide the extension rod 432 downward along the side hanging groove 2135 into the side hanging groove 2135. Part of the extension rod 432 is located in the side hanging groove 2135, and the second frame unit 42 abuts against the hook 2133. Thus, the second energy storage unit 41 and the second frame unit 42 are connected to the second connection module 213 through the hanging unit 43, ensuring the stability of the second energy storage component 04 on the vehicle.

[0067] Those of ordinary skill in the art can understand that the above embodiments are specific cases for implementing the present disclosure, and in practical applications, various changes can be made to them in form and details without departing from the scope of the present disclosure.
