Figure 4 yes Figure 1FIG. 1 is a schematic partial cross-sectional view of the protection device 100. Figures 1 to 4 As shown, in a specific embodiment, the protective device 100 for a vehicle battery includes a fixed pad 10 and at least one shock absorbing component 20. The fixed pad 10 has at least one through-hole 11 for dissipating heat for the battery. The shock absorbing component 20 is arranged in the air outlet 11 for shock absorbing the battery. The shock absorbing component 20 is arranged to allow the airflow at one end of the air outlet 11 to flow to the other end. Here, the shock absorbing component 20 is used to reduce the force on the surface of the fixed pad 10, so as to achieve the effect of shock absorbing the battery. The air outlet 11 is through-hole along the thickness direction of the fixed pad 10. The number of air outlets 11 and the number of shock absorbing components 20 can be set according to specific design requirements.
[0040] In this embodiment, an air vent 11 is provided on the fixing pad 10, so that the heat on the surface of the battery can be discharged through the air vent 11, thereby dissipating the heat of the battery. In addition, a shock absorbing component 20 is provided in the air vent 11, which can absorb the vibration and impact force generated by the vehicle during driving while dissipating the heat of the battery, thereby achieving the effect of shock absorbing the battery.
[0041] In this embodiment, there are multiple air outlet holes 11 and shock absorbing components 20, and each shock absorbing component 20 is correspondingly arranged in one air outlet hole 11. In other embodiments, multiple shock absorbing components 20 can also be arranged in each air outlet hole 11, which can be set according to actual needs. In this embodiment, a plurality of air outlet holes 11 are opened on the fixing pad 10, and the heat on the surface of the battery can be discharged through the air outlet holes 11, thereby achieving the purpose of heat dissipation, and shock absorbing components 20 are arranged inside the plurality of air outlet holes 11, so that a more comprehensive shock absorbing effect can be achieved.
[0042] In a preferred embodiment, the plurality of air outlet holes 11 are evenly arranged on the fixed pad 10, and at least one channel 13 is provided between two adjacent air outlet holes 11.

The two conducting components 30 are respectively arranged at the top and bottom of the corresponding air outlet 11, and the two conducting components 30 are arranged to allow the airflow at one end of the air outlet 11 to flow to the other end. The elastic component 40 is arranged between the two conducting components 30, and the two ends are respectively abutted against the two conducting components 30. In this embodiment, the shock absorbing component 20 is arranged in the air outlet 11, and it is necessary to avoid affecting the fluidity of the gas to avoid affecting the heat dissipation of the battery, so the shock absorbing component 20 needs to be arranged to be through, that is, to allow the airflow on one side of the fixing pad 10 to flow to the other side through the shock absorbing component 20. In this embodiment, the shock absorbing component 20 is completely filled in the air outlet 11, so it is necessary to set a vent on the shock absorbing component 20 to allow the gas to circulate, that is, the heat to circulate, so as to avoid affecting the heat dissipation of the battery.

In other embodiments, the heat conducting sheet 21 can also be made of other thermally conductive materials. The airflow on both sides of the fixing pad 10 circulates through the first vent 231 and the second vent 211.

In this embodiment, the outer side surface of the stop ring 22 abuts against the inner wall of the air outlet 11, and the outer side surface of the conducting tube 23 also abuts against the inner wall of the air outlet 11.
[0047] In this embodiment, the elastic component 40 includes a rubber plate 26 and at least one spring 25. The rubber plate 26 is arranged between two conductive components 30 and is provided with at least one third vent hole 261. The rubber plate 26 defines a cavity 27 between the two conductive components 30, and each cavity 27 is connected to a channel 13. The spring 25 is arranged in the cavity 27, and the two ends are respectively in contact with the rubber plate 26 and the conductive component 30. Heat can enter through the second vent hole 211 of the heat conductive sheet 21, and then pass through the first vent hole 231 of the conductive tube 23 and the third vent hole 261 of the rubber plate 26, and then be discharged from the vent hole of the conductive component 30 on the other side. Here, the number of the first vent hole 231, the second vent hole 211 and the third vent hole 261 is multiple. When the number of the spring 25 is one, the spring 25 is located in the upper cavity 27 or in the lower cavity 27. In a preferred embodiment, there are two springs 25 , and the two springs 25 are respectively located in two cavities 27 .
[0048] In this embodiment, at least one taking groove 14 is provided on the fixing pad 10, and a hand-held component 12 for taking the fixing pad 10 is provided at the taking groove 14. Here, the hand-held component 12 is a rope, and the user can take the protection device 100 by holding the hand-held component 12. In this embodiment, there are a plurality of taking grooves 14, and a hand-held component 12 is provided at each taking groove 14.
[0049] This embodiment further provides a vehicle, which includes the above-mentioned protection device 100. The protection device 100 is not described in detail here.
[0050] After the protective device 100 of this embodiment is installed, the heat on the battery surface can be discharged through the air outlet 11 of the fixing pad 10, which effectively solves the problem that the heat of the battery cannot be discharged, resulting in excessively high surface temperature of the battery and affecting the battery life. At the same time, vibration is easy to occur during the driving of the car, and the shock-absorbing component 20 located in the air outlet 11 can absorb vibration and impact and reduce the impact of vibration on the battery.
