DETAILED DESCRIPTION
[0023] The present invention will be further described in detail below in conjunction with specific implementations and with reference to the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present invention and its application.
[0024] like Figure 1 As shown, it is a schematic diagram of the overall exploded structure of a shock absorbing device for a vehicle-mounted high-temperature sodium battery provided in this embodiment. The device includes a first shock absorbing plate 1 and a second shock absorbing plate 2 of the same size. It can be understood that the size of the first shock absorbing plate 1 and the second shock absorbing plate 2 should be slightly larger than the size of the high-temperature sodium battery 8, so as to facilitate the fixation of the high-temperature sodium battery 8. In addition, in this embodiment, it is preferred that the first shock absorbing plate 1 and the second shock absorbing plate 2 are both square structures corresponding to the structure of the high-temperature sodium battery 8. Of course, in other embodiments of the present application, the structures of the first shock absorbing plate 1 and the second shock absorbing plate 2 may also be circular or polygonal; the first shock absorbing plate 1 and the second shock absorbing plate 2 are arranged relatively parallel, and between the first shock absorbing plate 1 and the second shock absorbing plate 2, An elastic shock-absorbing component is provided in the gap between the plates 2, and the elastic shock-absorbing component is composed of a shock-absorbing spring 4 and a shock-absorbing damping 5. Through the elastic shock-absorbing component, the deviation of the high-temperature sodium battery 8 in multiple directions can be effectively compensated and buffered, and the multi-directional position deviation of the high-temperature sodium battery 8 caused by vibration can be effectively prevented, thereby improving the stability and safety of the high-temperature sodium battery 8 during vehicle operation; at the same time, a battery fixing part is provided on the first shock-absorbing plate 1, and the battery fixing part is a fixing hole 12. The battery fixing hole 12 cooperates with the locking bolt 9 to fix the high-temperature sodium battery 8 on the first shock-absorbing plate 1, so that it is convenient to realize the integrated design of the shock-absorbing device and the high-temperature sodium battery 8, and can effectively ensure the maximum shock absorption effect.
[0025] It can be understood that in this embodiment, the first shock-absorbing plate 1 and the second shock-absorbing plate 2 should be made of high-temperature resistant material. In this embodiment, the first shock-absorbing plate 1 and the second shock-absorbing plate 2 are preferably made of aluminum, and the aluminum is specifically a high-temperature resistant aluminum alloy, such as aluminum-silicon alloy or aluminum-magnesium alloy, or the aluminum is specifically pure aluminum with an oxide film formed on the outside; aluminum is selected as the constituent material of the shock-absorbing plate because it has the advantages of light weight, high mechanical strength, and not easy to rust; in this embodiment, in order to further reduce the weight of the shock-absorbing device, it is preferred to set the first shock-absorbing plate 1 to a hollow structure with a hollow groove 11. Of course, when necessary, the second shock-absorbing plate 2 can also be designed as a hollow structure.
[0026] In the present embodiment, the shock absorbing spring 4 and the shock absorbing damping 5 both include multiple groups, wherein the multiple groups of shock absorbing springs 4 are evenly distributed between the first shock absorbing plate 1 and the second shock absorbing plate 2 near the edge, and the axis of the shock absorbing spring 4 is vertically arranged relative to the first shock absorbing plate 1 and the second shock absorbing plate 2, and the shock absorbing spring mainly plays a supporting and buffering role, and can absorb the impact force from the vertical direction; the multiple groups of shock absorbing damping 5 are evenly distributed between the first shock absorbing plate 1 and the second shock absorbing plate 2 near the middle, and the two ends of the shock absorbing damping 5 are respectively connected to two points on the first shock absorbing plate 1 and the second shock absorbing plate 2 whose orthographic projections do not overlap, that is, the shock absorbing damping 5 is obliquely arranged between the first shock absorbing plate 1 and the second shock absorbing plate 2, and its two ends are respectively connected to the first shock absorbing plate 1 and the second shock absorbing plate 2 through the fixing ear seats 6. Although the oblique arrangement of the shock absorbing damping 5 also has a certain elastic support The first shock absorbing plate 1 has a supporting effect, but its main purpose is to control the horizontal movement of the high-temperature sodium battery 8 located on the first shock absorbing plate 1, thereby reducing the vibration amplitude of the high-temperature sodium battery 8 in the horizontal direction; it can be seen that the elastic shock absorbing component of the layout structure in this embodiment can allow the shock absorbing device to have a certain degree of displacement in both the vertical and horizontal directions, and absorb the buffering forces in different directions respectively through the shock absorbing spring 4 and the shock absorbing damping 5, so that on the one hand, the elasticity (flexibility) performance and shock absorbing performance of the shock absorbing device are improved to avoid damage to the shock absorbing device, and on the other hand, the multi-directional position deviation caused by the vibration to the high-temperature sodium battery 8 can be effectively prevented, thereby effectively absorbing and reducing the vibration generated by the high-temperature sodium battery 8 during the operation of the vehicle, thereby improving the stability and safety of the high-temperature sodium battery 8, and at the same time, the performance and life of the high-temperature sodium battery 8 are also improved.
[0027] It can be understood that in this embodiment, the specific inclination angle of the shock-absorbing damper 5 is determined according to the actual effect and the material selection. In this embodiment, the inclination angle of the shock-absorbing damper 5 is preferably between 30° and 45°.
[0028] In other embodiments of the present application, when necessary, multiple groups of shock-absorbing springs 4 and shock-absorbing dampers 5 can also be vertically arranged relative to the first shock-absorbing plate 1 and the second shock-absorbing plate 2 to support the first shock-absorbing plate 1 while providing elastic support in the vertical direction. The elastic shock-absorbing component in this structure can mainly absorb and buffer the impact force in the vertical direction to reduce the vibration of the high-temperature sodium battery 8 in the vertical direction during the operation of the vehicle.
[0029] In this embodiment, corresponding positions of the first damping plate 1 and the second damping plate 2 are respectively provided with limiting columns 7, and the number of the limiting columns 7 corresponds to the number of the damping springs 4. In this embodiment, preferably, eight damping springs 4 are provided, that is, eight corresponding limiting columns 7 are provided, and the eight limiting columns 7 are equidistantly arranged around the first damping plate 1 and the second damping plate 2 near the edge position, such as Figure 2-5 As shown, the two ends of the damping spring 4 can be nested on the limiting column 7 to fix and limit the damping spring 4. The height of the limiting column 7 can be such that the damping spring 4 can be firmly limited.
[0030] In this embodiment, two points on the first shock absorbing plate 1 and the second shock absorbing plate 2 where the orthographic projections do not overlap are respectively provided with fixing ear seats 6, the number of fixing ear seats 6 on any shock absorbing plate corresponds to the number of shock absorbing dampers 5, and the two ends of the shock absorbing dampers 5 are respectively connected to the fixing ear seats 6 on the first shock absorbing plate 1 and the second shock absorbing plate 2 by fixing bolts 10 to fix the shock absorbing dampers 5.
[0031] As a preferred embodiment of the present application, a shock-absorbing and high-temperature resistant pad 3 is provided at the upper end of the first shock-absorbing plate 1. The size of the shock-absorbing and high-temperature resistant pad 3 is slightly larger than the size of the high-temperature sodium battery 8. In this embodiment, the size of the shock-absorbing and high-temperature resistant point preferably corresponds to the size of the first shock-absorbing plate 1 and the second shock-absorbing plate 2. The shock-absorbing and high-temperature resistant point is provided with threaded holes corresponding to the position and number of the battery fixing holes 12 on the first shock-absorbing plate 1. The threaded holes cooperate with the locking bolts 9 to fix it with the high-temperature resistant sodium battery 8 and are located between the first shock-absorbing plate 1 and the high-temperature sodium battery 8. The use of the shock-absorbing and high-temperature resistant pad can protect the metal outer surface of the high-temperature resistant sodium battery 8 on the one hand to ensure that it is not worn. On the other hand, compared with the shock-absorbing spring 4 and the shock-absorbing damper 5, it directly contacts the bottom of the high-temperature resistant battery, which can avoid the resonance phenomenon between the high-temperature sodium battery 8 and the shock-absorbing device.
[0032] In this embodiment, the shock-absorbing and high-temperature resistant pad 3 is made of polytetrafluoroethylene, which has a temperature resistance range of -200°C to 260°C and can work stably under various ambient temperatures.
[0033] In summary, this embodiment provides a shock-absorbing and high-temperature resistant pad 3 between the high-temperature sodium battery 8 and the first shock-absorbing plate 1, which not only meets the temperature requirement of the high-temperature sodium battery 8, but also realizes the wear protection of the outside of the high-temperature sodium battery 8. At the same time, it can also avoid the resonance phenomenon between the high-temperature sodium battery 8 and the shock-absorbing device.
[0034] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several improvements can be made without departing from the premise of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of the claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
