[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] Please refer to the following Figure 1-8 A vehicle 100 according to an embodiment of the present invention is described.

[0035] Reference Figure 1 , Figure 3 , Figure 6 and Figure 8 According to the vehicle 100 of the embodiment of the present utility model, the vehicle 100 includes: a vehicle body 10, a battery pack 20, a vibration reduction structure 30 and a fastener 40.

[0036] Specifically, a first fixing hole 11 is provided on the vehicle body 10; a second fixing hole 221 is provided on the battery pack 20; a through hole 312 is formed on the vibration reduction structure 30, and a shear thickening material piece 32 is provided in the vibration reduction structure 30; the fastener 40 passes through the through hole 312, the first fixing hole 11 and the second fixing hole 221 to connect the battery pack 20 to the vehicle body 10.

[0037] For example, Figure 1, Figure 3 , Figure 6 and Figure 8 As shown, a first fixing hole 11 is provided on the vehicle body 10, and the second fixing hole 221 of the battery pack 20 and the through hole 312 of the vibration reduction structure 30 both correspond to the first fixing hole 11, and the fastener 40 passes through the through hole 312, the second fixing hole 221 and the first fixing hole 11 to fix the battery pack 20 on the vehicle body 10.

[0038] When installing the battery pack 20 on the vehicle body 10, first align the second fixing hole 221 of the battery pack 20 with the first fixing hole 11, then align the through hole 312 of the vibration reduction structure 30 with the first fixing hole 11 and the second fixing hole 221, and finally, use the fastener 40 to pass through the through hole 312, the first fixing hole 11 and the second fixing hole 221. At this time, the battery pack 20 is fixed to the vehicle body 10.

[0039] During the driving of the vehicle 100, when the vehicle 100 passes over a bumpy road, the vibration of the vehicle body 10 will generate an instantaneous impact force, which is transmitted to the battery pack 20 through the vibration damping structure 30 via the rigid connection between the fastener 40 and the vehicle body 10. At this time, the shear thickening material 32 in the vibration damping structure 30 will undergo a phase change. For example, the shear thickening material 32 changes from a liquid phase to a solid phase to form a hard vibration isolation buffer layer, which can absorb a large amount of impact energy and achieve the purpose of buffering, vibration filtering or vibration reduction. When the vehicle 100 passes over a flat road, when the vibration damping structure 30 is not subjected to shear force, the shear thickening material 32 exhibits liquid characteristics, thereby not generating excessive resistance to the connection between the power battery pack 20 and the chassis of the vehicle 100, thereby improving the driving stability and ride comfort of the vehicle 100.

[0040] The vehicle 100 of the utility model is provided with a shear thickening material piece 32 on the vibration reduction structure 30. The shear thickening material piece 32 can undergo a phase change according to the magnitude of the instantaneous impact force generated by the vibration of the vehicle body 10. During the driving of the vehicle 100, the impact energy can be absorbed, and the influence of the instantaneous impact force on the battery pack 20 can be reduced, thereby effectively reducing the vibration of the battery pack 20, thereby protecting the battery pack 20 and improving the safety of the battery pack 20. At the same time, the shear thickening material piece 32 has good stability and weather resistance, thereby being able to adapt to different working environments and requirements, thereby improving the stability of the vibration reduction effect of the vibration reduction structure 30 on the battery pack 20.

[0041] According to the vehicle 100 of the embodiment of the utility model, a shear thickening material piece 32 is arranged on the vibration reduction structure 30, which can absorb impact energy and reduce the influence of instantaneous impact force on the battery pack 20, thereby protecting the battery pack 20 and improving the safety of the battery pack 20. At the same time, the shear thickening material can adapt to different working environments and requirements, thereby improving the stability of the vibration reduction effect of the vibration reduction structure 30 on the battery pack 20.

[0042] According to some embodiments of the present invention, referring to Figure 3 and Figure 8 The vibration reduction structure 30 includes a packaging body 31, a through hole 312 along the up and down direction (such as Figure 3 The package body 31 is formed with a receiving cavity 311, and the shear thickening material piece 32 is arranged in the receiving cavity 311. Therefore, the receiving cavity 311 of the package body 31 can provide a layout space for the shear thickening material piece 32, which is convenient for the layout of the shear thickening material piece 32. At the same time, the through hole 312 is reasonably arranged, so that the fastener 40 can be conveniently inserted into the through hole 312.

[0043] For example, Figure 3 and Figure 8 As shown, the through hole 312 is provided in the middle of the package body 31, and the through hole 312 penetrates the package body 31 in the up-down direction. Preferably, the cross section of the package body 31 may be circular or polygonal, so that a suitable cross section of the package body 31 may be selected according to actual needs, thereby improving the versatility of the package body 31.

[0044] According to some optional embodiments of the present invention, referring to Figure 4 and Figure 5 The package body 31 defines one or more accommodating cavities 311. When there are multiple accommodating cavities 311, that is, when there are two, three, four or more accommodating cavities 311, the multiple accommodating cavities 311 are arranged at intervals in the vertical direction. Therefore, when there is one accommodating cavity 311, it is convenient to fill the shear thickening material piece 32, thereby improving the filling efficiency. At the same time, when there are multiple accommodating cavities 311, the shear thickening material pieces 32 in the multiple accommodating cavities 311 can jointly absorb the instantaneous impact force generated by the vibration of the vehicle body 10, thereby ensuring the vibration reduction effect of the vibration reduction structure 30.

[0045] For example, Figure 4 and Figure 5As shown, the packaging body 31 can define a accommodating cavity 311, and the shear thickening material piece 32 is filled in the entire accommodating cavity 311. The cavity volume filling rate of the shear thickening material piece 32 is 95%-100%, thereby ensuring the energy absorption effect of the shear thickening material piece 32. The packaging body 31 can define a plurality of accommodating cavities 311, and the plurality of accommodating cavities 311 are arranged at intervals in the up and down directions, and the height of a single accommodating cavity 311 is greater than or equal to 1 mm, thereby ensuring the energy absorption effect of the shear thickening material piece 32.

[0046] According to some embodiments of the present invention, referring to Figure 4 and Figure 5 , the package body 31 is a metal part or a polymer material part. Therefore, it can be ensured that the package body 31 can be deformed normally, so that the shear thickening material part 32 can be deformed normally, and then the vibration reduction effect of the vibration reduction structure 30 can be ensured. Preferably, the thickness of the top wall of the package body 31 is 3mm-5mm, and the thickness of the side wall of the package body 31 is 1mm-5mm. Such a setting can ensure that the package body 31 can bear the instantaneous impact force in the vertical direction, thereby preventing the package body 31 from being damaged and ensuring the service life of the package body 31.

[0047] According to some embodiments of the present invention, referring to Figure 4 and Figure 5 The shear thickening material 32 is a shear thickening fluid or a shear thickening colloid. Thus, the shear thickening material 32 can absorb the impact energy, and thus the vibration reduction effect of the vibration reduction structure 30 can be ensured.

[0048] For example, a shear-thickening fluid is a thixotropic sol composed of dispersed phase particles and a liquid dispersion medium. There is an obvious hydrogen bonding effect between the dispersed phase particles and the liquid dispersion medium. When the fluid is subjected to high-speed shear, its viscosity will suddenly increase, and it may even change from a liquid to a solid or solid-like substance. When the external force is removed, it quickly returns to a liquid, exhibiting a reversible non-Newtonian fluid behavior. A shear-thickening colloid is a solid organic borosiloxane polymer. Under normal conditions, it is a soft high-molecular viscoelastic solid. Once it is hit quickly by the outside world, its storage modulus and strength instantly increase several times, showing hard solid properties. When the external force disappears, it returns to its original soft state.

[0049] According to some embodiments of the present invention, referring to Figure 3 and Figure 6 The vibration reduction structure 30 is disposed on the side of the battery pack 20 that is away from the vehicle body 10 (eg Figure 2The lower side of the battery pack 20 shown in the figure). Therefore, this arrangement is reasonable. When the instantaneous impact force generated by the vibration of the vehicle body 10 is transmitted to the battery pack 20 through the fastener 40, it will be first transmitted to the vibration reduction structure 30 and then to the battery pack 20, thereby reducing the vibration of the battery pack 20 caused by the instantaneous impact force, and further protecting the battery pack 20.

[0050] According to some optional embodiments of the present invention, referring to Figure 3 and Figure 6 The vehicle 100 may further include: a partition 50, the partition 50 is arranged on a side of the vibration reduction structure 30 away from the battery pack 20 (such as Figure 1 The partition 50 is provided with a through hole which is opposite to and connected with the through hole 312, and the fastener 40 is passed through the through hole. Thus, the partition 50 can form a barrier between one end of the fastener 40 and the vibration damping structure 30, so as to prevent one end of the fastener 40 from directly contacting the vibration damping structure 30, so that the partition 50 can effectively protect the vibration damping structure 30, and further prevent the package 31 of the vibration damping structure 30 from being damaged.

[0051] According to some optional embodiments of the present invention, referring to Figure 3 and Figure 6 The vehicle 100 may further include: a limiting plate 60, the limiting plate 60 extending in a ring shape along the circumference of the partition 50, the limiting plate 60 being connected to the partition 50 and being located on a side of the partition 50 facing the vehicle body 10 (such as Figure 1 The limiting plate 60 cooperates with the partition plate 50 to define a limiting groove open on the upper side, and one end of the vibration reduction structure 30 (such as Figure 2 The lower end of the vibration reduction structure 30 shown in FIG. 3 is disposed in the limiting groove, and the other end of the vibration reduction structure 30 (as shown in FIG. Figure 2 The upper end of the vibration reduction structure 30 shown in the figure abuts against the battery pack 20.

[0052] In this way, the vibration damping structure 30 is arranged in the installation groove, which can prevent the vibration damping structure 30 from being separated from the fastener 40, thereby ensuring the stability of the connection between the vibration damping structure 30 and the fastener 40. At the same time, the limiting groove provides an installation space for the vibration damping structure 30, thereby facilitating the arrangement of the vibration damping structure 30. In addition, the other end of the vibration damping structure 30 abuts against the battery pack 20, thereby ensuring that the instantaneous impact force generated by the vibration of the vehicle body 10 is transmitted to the battery pack 20 only after the vibration damping structure 30 absorbs energy, thereby effectively protecting the battery pack 20.

[0053] Preferably, the height difference between the vibration damping structure 30 and the limiting plate 60 can be 50mm-60mm, thereby preventing the limiting plate 60 from being too high and affecting the installation of the vibration damping structure 30. At the same time, it can also prevent the vibration damping structure 30 from being too low and causing the vibration damping structure 30 to detach from the limiting groove.

[0054] Furthermore, a fastening bolt 70 is provided on the upper surface of the vehicle body 10 , and a first fixing hole 11 is defined in the fastening bolt 70 . The lower end of the fastener 40 abuts against the limiting plate 60 , and the upper end of the fastener 40 passes through the first fixing hole 11 of the fastening bolt 70 and is threadedly connected to the fastening bolt 70 .

[0055] Furthermore, if Figure 6 and Figure 8 As shown, the partition plate 50 and the limiting plate 60 form a sleeve with an open upper side, the lower end of the vibration reduction structure 30 is arranged in the sleeve, and the upper end of the vibration reduction structure 30 abuts against the battery pack 20. Preferably, the gap between the vibration reduction structure 30 and the inner wall of the sleeve is 1mm-3mm, so that the installation of the vibration reduction structure 30 can be facilitated, and at the same time, the gap between the vibration reduction structure 30 and the sleeve can be prevented from being too large, causing the vibration reduction structure 30 to shake in the sleeve.

[0056] In addition, the ratio between the diameter of the sleeve and the diameter of the fastener 40 can be 2.5-3.5, thereby ensuring the stability of the fastener 40 fixing the sleeve, and the ratio between the diameter of the vibration reduction structure 30 and the diameter of the fastener 40 can be 0.5-2.5, thereby ensuring the stability of the fastener 40 fixing the sleeve.

[0057] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 The battery pack 20 includes a tray 21, the upper end of the tray 21 (such as Figure 1 A horizontally extending connecting plate 22 is provided along the upper end of the tray 21 shown in the figure. The connecting plate 22 extends along the circumference of the tray 21, and the second fixing hole 221 passes through the connecting plate 22 in the up-down direction. Thus, the tray 21 can protect the outer side of the battery pack 20, thereby preventing the battery pack 20 from being damaged. At the same time, the connecting plate 22 is connected to the vehicle body 10, so that the fastener 40 can be conveniently fixed to the vehicle body 10 after passing through the connecting plate 22. In addition, the second fixing hole 221 is reasonably arranged, and when the battery pack 20 is fixed to the vehicle body 10, it will not affect the battery module in the battery pack 20.

[0058] For example, Figure 1 and Figure 2 As shown, a connecting plate 22 is formed on the periphery of the tray 21 , and the connecting plate 22 extends in a direction away from the tray 21 . A second fixing hole 221 is provided on the connecting plate 22 , and the second fixing hole 221 penetrates the connecting plate 22 in the up-down direction.

[0059] According to some embodiments of the present invention, referring to Figure 1 and Figure 2The outer edge of the connecting plate 22 is provided with a folded edge 23 extending downward, and the vibration-damping structure 30 and the fastener 40 are provided on the side of the folded edge 23 facing the tray 21. Thus, the folded edge 23 can protect the vibration-damping structure 30 and the fastener 40, and prevent the vibration-damping structure 30 and the fastener 40 from being directly hit by external structures and causing damage to the vibration-damping structure 30 and the fastener 40, thereby ensuring the service life of the vibration-damping structure 30 and the fastener 40.

[0060] Furthermore, if Figure 1 and Figure 2 As shown, there are multiple fasteners 40 and vibration damping structures 30, that is, the number of fasteners 40 and vibration damping structures 30 can be two, three or four or more, and the fasteners 40 and vibration damping structures 30 correspond one to one. Thus, a fastener 40 and a vibration damping structure 30 form a vibration damping assembly fixed on the connecting plate 22, and multiple vibration damping assemblies are arranged at intervals on the connecting plate 22, so as to ensure the vibration damping effect of the vibration damping structure 30 and at the same time, ensure the reliability of the connection between the battery pack 20 and the vehicle body 10.
