Description

Technical Field

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

[0002] Currently, large-capacity batteries are widely used as power sources in the field of new energy vehicles. To meet the endurance requirements, the battery is usually arranged in the chassis area of ​​the vehicle and connected to the body structure through a fixed bracket on the battery. The battery cells inside the battery are usually square or cylindrical, and the battery cells are arranged in a regular arrangement. The battery cells are then wrapped with box components to form a battery. The space for installing batteries in the vehicle needs to be reserved according to the size of the battery cells and protection requirements. Some solutions increase capacity by horizontally expanding the layout, but such designs often require simultaneous adjustments to the vehicle chassis structure.

[0003] When pursuing large capacity, the battery layout method tends to increase the width of the vehicle, thus affecting the vehicle's handling stability and riding space. Therefore, the battery is placed at the bottom of the vehicle's beam using the space of the vehicle's beam. However, when the vehicle's beam is connected to the battery, it is necessary to add a connecting component between the battery and the beam along the width of the vehicle to ensure the stability of the battery and the vehicle's beam, which further increases the width of the vehicle where the battery is installed.

[0020] In this embodiment, in the structure of the new energy vehicle, the battery is usually arranged inside the vehicle body or in the chassis area, which has the problem of limited installation space. In the prior art, it is necessary to add a connecting component between the battery and the beam 11 along the width direction of the vehicle, which makes it difficult to achieve a compact fit between the battery and the body beam 11, resulting in low space utilization. Therefore, in order to solve the above problems, the present invention provides a new energy vehicle, such as Figure 1 , Figure 2 As shown, the new energy vehicle may include a vehicle component 01 , a fixed component 02 , a first energy storage component 03 , and a second energy storage component 04 .

[0021] The vehicle assembly 01 may include two beams 11 and a connecting beam 12. The two beams 11 may be spaced apart along the width direction of the beams 11, and one end of the connecting beam 12 may be connected to one beam 11 and the other end may be connected to another beam 11, thereby forming a stable structure.

[0022] like Figure 4 , Figure 6 As shown, the fixing assembly 02 may include a fixing unit 21 and a locking unit 22. One end of the fixing unit 21 may be connected to the beam 11, and the other end may extend along the height direction of the beam 11. The beam 11 may be firmly connected to the first energy storage assembly 03 and the second energy storage assembly 04 through the fixing assembly 02.

[0023] The first energy storage assembly 03 may include a first energy storage unit 31 and a first frame unit 32. Part of the first energy storage unit 31 may be arranged 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 beams 11. The ratio of the width of the first energy storage unit 31 to the shortest distance between the two beams 11 is less than or equal to 1 and greater than 0.95. This facilitates the connection between the first energy storage assembly 03 and the fixed unit 21 through the locking unit 22 after the first energy storage assembly 03 is moved from the top of the gap between the two beams 11 to the gap between the two fixed units 21, i.e., hoisting. Or after the first energy storage assembly 03 is moved from the bottom of the gap between the two beams 11 to between the two beams 11, the connection between the first energy storage assembly 03 and the fixed unit 21 is achieved through the locking unit 22, i.e., lifting. In this way, the first energy storage unit 31 can occupy the space between the two beams 11 as much as possible, ensuring that the first energy storage unit 31 can provide more cruising range for the vehicle. A fixed unit 21, a first energy storage component 03, and another fixed unit 21 can be arranged in sequence along the width direction of the first energy storage component 03. One end of the locking unit 22 can be detachably connected to the first frame unit 32, and the other end can be detachably connected to the fixed unit 21. If the spacing between the first frame unit 32 and the beam 11 along the width direction of the beam 11 and the size of the locking unit 22 along the width direction of the beam 11 are set to be equal, in the actual assembly process, due to processing tolerances, the width of the first energy storage component 03 may be greater than the spacing between the beams 11, and thus it is impossible to install it in the gap between the fixed units 21 by hoisting or lifting. Therefore, it is necessary to have a certain gap between the beam 11 and the first frame unit 32 so that the first energy storage component 03 and the fixed component 02 can be installed. Therefore, this solution allows S1<S2, S1 is the spacing between the first frame unit 32 and the beam 11 along the width direction of the beam 11. The spacing in the width direction of the beam 11, S2 is the size of the locking unit 22 along the width direction of the beam 11, so that the projection of the locking unit 22 toward the beam 11 is located below the spacing area between the two beams 11 and the beam 11, so that the beam 11 and the fixing unit 21 are directly set to be 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 not only ensures that the first energy storage component 03 can be installed in the gap between the fixing units 21 by hoisting or lifting, but also can ensure the endurance of the vehicle by the first energy storage unit 31 as much as possible.

[0024] The second energy storage assembly 04 can be detachably connected to the side of the locking unit 22 away from the first energy storage assembly 03, so that the endurance of the vehicle can be further improved by adding the second energy storage assembly 04. When the first energy storage assembly 03 and the second energy storage assembly 04 are respectively installed on the beam 11, the projections of the first energy storage assembly 03 and the second energy storage assembly 04 along the height direction of the first energy storage assembly 03 are spaced from the beam 11 and the connecting beam 12, thereby avoiding interference between the first energy storage assembly 03 and the second energy storage assembly 04 when they are respectively connected to the beam 11.

[0025] In this embodiment, if Figure 3 As 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 arranged at intervals 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 width of the first frame 321 and the width of the second frame 322 may be less than or equal to the shortest spacing between the two beams 11, respectively, so that the first frame 321 and the second frame 322 are moved from the gap between the two beams 11 to the gap between the two fixing units 21, and the first frame 321 and the second frame 322 are connected to the fixing unit 21 through the locking unit 22, that is, hoisting or lifting. Thereby, the first frame unit 32 can occupy the space between the two beams 11 as much as possible, ensuring that the first energy storage unit 31 can provide more cruising range for the vehicle.

[0026] When the vehicle is stationary, the strength of the first support rod 323 is sufficient to ensure the connection between the first energy storage assembly 03 and the fixing unit 21. However, during the vehicle's driving, the vehicle will continue to vibrate, and the first support rod 323 is insufficient in strength, which may easily cause the frame structure of the first frame unit 32 to deform, and eventually cause damage to the first energy storage unit 31. Therefore, the present solution provides a locking unit 22, such 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, the first energy storage assembly 03 can be fixed by the locking unit 22, and it can also serve as a reinforcing rod 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.

[0027] In other embodiments, Figure 8 As 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 spaced apart in 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, and the second frame unit 42 may 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.

[0028] In other embodiments, Figure 4 As shown, when the first energy storage component 03 is lifted or hoisted, the bolt needs to 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, since the position of the first energy storage component 03 and the position of the fixing unit 21 may be offset, the bolt cannot connect the first energy storage component 03 with the fixing unit 21 through the locking unit 22. Therefore, an oblong hole is used at the connection between the locking unit 22 and the fixing unit 21 of this solution. The length direction of the oblong hole is set along the width direction of the vehicle. The oblong hole can adapt to the spacing between the fixing unit 21 and the first energy storage component 03, avoiding the offset between the fixing unit 21 and the first energy storage component 03, which causes the bolt to be unable to pass through the first frame unit 32 and the locking unit 22 in sequence.

[0029] In this embodiment, if Figure 7 , Fig.11As shown, the fixing unit 21 may include a fixing body 211, a first connecting module 212, a second connecting module 213, and a connecting rod 214. The fixing body 211 may be detachably connected to the beam 11. The first connecting module 212 may be set to a flexible material, the first connecting module 212 may be connected to the fixing body 211, one end of the connecting rod 214 may be connected to the first connecting module 212, and the other end may extend toward the direction close to the first energy storage unit 31. When the beam 11 is twisted and deformed, the first connecting module 212 absorbs most of the stress through its own deformation, thereby preventing the deformation generated when the beam 11 is twisted from being transmitted to the first energy storage unit 31, 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 another connecting rod 214 are sequentially arranged along the width direction of the first energy storage assembly 03. One end of the second connection module 213 is connected to the connection rod 214 , and the other end is detachably connected to the second energy storage assembly 04 , thereby facilitating efficient installation among the fixed body 211 , the first connection module 212 , the second connection module 213 , and the connection rod 214 .

[0030] In other embodiments, the fixing unit 21 may further include a bearing rod 215, one end of which is detachably connected to an end of the connecting rod 214 away from the fixed body 211, and the other end is detachably connected to an end of another connecting rod 214 away from the fixed 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 to the gap of the beam 11. Thereby, the bearing rod 215 can bear the gravity load of the first energy storage assembly 03, further enhancing the stability of the first energy storage assembly 03.

[0031] In this embodiment, if Fig.12 , Fig.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 is absorbed by the deformation of the first buffer ring 2121 itself, thereby preventing the deformation generated when the beam 11 is twisted from being transmitted to the first energy storage unit 31. The first mounting portion 2122 may be made of a rigid material, and 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 to ensure that the relative position of the first mounting portion 2122 and the fixed body 211 will not be offset. The inner circumferential wall of the first buffer ring 2121 may be connected to the outer circumferential wall of the first mounting portion 2122. The minimum angle between the axial direction of the first mounting portion 2122 and the height direction of the beam 11 is 25°~90°. The end of the connecting rod 214 close to the beam 11 is detachably connected to the outer peripheral wall of the first buffer ring 2121. Vibration will be generated during the driving of the vehicle. The first energy storage component 03 applies a downward force to the first buffer ring 2121 through the connecting rod 214 to prevent the first buffer ring 2121 from being subjected to excessive axial force, causing the first buffer ring 2121 and the first mounting portion 2122 to slide relative to each other along the axial direction of the first buffer ring 2121 until the first buffer ring 2121 and the first mounting portion 2122 are spaced apart. In this way, the force on the first buffer ring 2121 can be converted into compression deformation of the first buffer ring 2121, thereby improving the pull-off resistance of the first connection module 212.

[0032] In this embodiment, if Figure 6 As shown, since the first energy storage assembly 03 will shake along the width direction of the vehicle body during driving, causing the beam 11 to deform, the axial direction of the first mounting portion 2122 is set parallel to the length direction of the beam 11. Fig.11 In the left and right directions shown, the vibration and shaking of the vehicle exert an axial force on the first buffer ring 2121, so that the first buffer ring 2121 and the first mounting portion 2122 are not easily separated. The radial thickness of the first buffer ring 2121 can be fully utilized to absorb vibration and deformation, thereby preventing the deformation and impact of the beam 11 from being transmitted to the first energy storage component 03.

[0033] In this embodiment, if Fig.10 , Fig.12 As shown, the first buffer ring 2121 can allow the first energy storage component 03 and the beam 11 to move relative to each other. However, if the relative displacement between the first energy storage component 03 and the beam 11 is too large during vehicle driving, the center of gravity of the vehicle will change too much, making the vehicle difficult to control. Therefore, the second connecting module 213 is flexibly connected to the fixed body 211 at one end away from the connecting rod 214, thereby limiting the relative displacement between the first energy storage unit 31 and the beam 11 through the flexible connection of the second connecting module 213, so that the vehicle can travel on the road more smoothly.

[0034] In this embodiment, if Figure 5 , Figure 6 As shown, the second connection module 213 may include a second buffer ring 2131 and a side hanging part 2132. The outer circumference of the second buffer ring 2131 may be connected to the fixed body 211. The inner circumference of the second buffer ring 2131 may be connected to the side hanging part 2132. One end of the side hanging part 2132 away from the second buffer ring 2131 is connected to the connecting rod 214, and the axial direction of the second buffer ring 2131 is parallel to the height direction of the beam 11. The second buffer ring 2131 can better limit the radial movement of the side hanging part 2132 along the second buffer ring 2131, thereby cooperating with the first buffer ring 2121, so that the first energy storage component 03 can be relatively displaced with the beam 11, and the displacement is controlled within a reasonable range. The second energy storage component 04 is detachably connected to the side hanging part 2132. In this way, the stability of the vehicle during driving can be ensured, and the load of the beam 11 can be prevented from being transferred to the first energy storage unit 31 to cause damage to the first energy storage unit 31.

[0035] In this embodiment, if Figure 3 , Figure 6 As shown, the second connection module 213 may also include a hook 2133, a side hanging hole 2134, and a side hanging slot 2135. One end of the hook 2133 may be connected to the side hanging portion 2132, and the other end may extend toward the direction close to the first energy storage assembly 03. The hook 2133 may withstand the vertical downward gravity load of the second energy storage assembly 04. The side hanging hole 2134 and the side hanging slot 2135 may respectively penetrate the two sides of the side hanging portion 2132 along the width direction of the beam 11. The side hanging hole 2134 may be connected to the side hanging slot 2135, and the radial direction of the side hanging hole 2134 may coincide with the length direction of the side hanging slot 2135. The length direction of the side hanging slot 2135 is Figure 7 The side hanging slot 2135 is arranged below the side hanging hole 2134 , and the hole diameter of the side hanging hole 2134 is larger than the slot width of the side hanging slot 2135 .

[0036] like Figure 8 , Fig. 9As shown, the second energy storage assembly 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 arranged in 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 slot width of the side hanging slot 2135. The diameter of the extension rod 432 is smaller than the slot width of the side hanging slot 2135. The hook 2133, the second frame unit 42, and the suspension body 431 are sequentially abutted from the bottom end of the beam 11 to the top end of the beam 11. The bolt passes through the hook 2133, the second frame unit 42, and the suspension body 431 in sequence, so that the second frame unit 42 is detachably connected to the hook 2133 and the suspension body 431 respectively, and the relative position of the second storage assembly and the fixed unit 21 is limited in this way. When the second energy storage assembly 04 moves to connect with the fixed assembly 02, the clamping part 433 is moved to the inside of the side hanging hole 2134 along the side hanging hole 2134 to the first energy storage assembly 03, and then slides downward along the side hanging groove 2135 to the side hanging groove 2135. The diameter of the clamping part 433 is smaller than the aperture of the side hanging hole 2134 and larger than the groove width of the side hanging groove 2135 to prevent disengagement, so that the bolt passes through the hook 2133, the second frame unit 42, and the suspension body 431 in sequence, and then the second storage assembly is locked.

[0037] In other embodiments, the second energy storage unit 41 may include a third energy storage unit 411 and a fourth energy storage unit 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 unit 411. The third frame 421 is arranged on a side of the fourth frame 422 close to the beam 11. The fourth energy storage unit 412 is connected to the second frame 322. The third energy storage unit 411 is arranged in a space surrounded by the second frame unit 42. Through the third energy storage unit 411 and the fourth energy storage unit 412, more energy can be provided for the vehicle to increase the endurance of the vehicle.

[0038] The vehicle component 01 may further include a driving unit, which may be a wheel, so that the driving unit ensures that the vehicle can travel normally on the road.

[0039] In this embodiment, if 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 connect the first energy storage part 311. The first frame 321 can be arranged on the side of the second frame 322 close to the beam 11. The second energy storage part 312 is connected to the first frame 321. The first energy storage part 311 is arranged in the space surrounded by the first frame unit 32. The ratio of the width of the first energy storage part 311 to the shortest spacing between the two beams 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 spacing between the two beams 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 beams 11, increase the vehicle's cruising range, and can also avoid. At least part of the second energy storage part 312 is arranged in the space between the two beams 11, and the second energy storage part 312 can further increase the vehicle's cruising range.

[0040] In this embodiment, the present invention provides an assembly method, which can be applied to any new energy vehicle in the above embodiments, such as Fig.14 As shown, the assembly method may include steps S10 to S30.

[0041] Step S10, based on the completion of the preliminary assembly, the first energy storage assembly 03 can be moved between the two fixed units 21. The preliminary assembly includes two beams 11 arranged at intervals along the width direction of the beam 11, one end of the connecting beam 12 is connected to one beam 11, and the other end is connected to the other beam 11, and one end of the fixed unit 21 is connected to the beam 11, and the other end extends along the height direction of the beam 11. The beam 11 provides a basic frame of the vehicle, which can be used to carry and assemble the first energy storage assembly 03 and the second energy storage assembly 04.

[0042] Step S20, if the first energy storage assembly 03 is installed by lifting, the bearing rod 215 needs to be disassembled first, and 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 distortion of the first frame unit 32 caused by vehicle vibration.

[0043] Step S30, based on connecting one end of the locking unit 22 to the first energy storage assembly 03 and connecting the other end of the locking unit 22 to the fixing unit 21, the second energy storage assembly 04 is connected to the side of the fixing unit 21 away from the first energy storage assembly 03. When installing the second energy storage assembly 04, the engaging portion 433 is moved to the inside of the side hanging hole 2134, and then slid downward along the side hanging slot 2135 through the extension rod 432 to the side hanging slot 2135, part of the extension rod 432 is located in the side hanging slot 2135, and the second frame unit 42 is abutted against the hook 2133, so that the second energy storage unit 41 and the second frame unit 42 are connected to the second connection module 213 through the suspension unit 43, thereby ensuring the stability of the second energy storage assembly 04 on the vehicle.
