specific Embodiment 1

[0033] Such as Figure 1 to Figure 2 and Figure 5 As shown, a battery pack anti-collision reinforcement structure for a new energy vehicle provided by an embodiment of the present invention includes a flat plate 1, a first vertical plate 3, a second vertical plate 4 and a linkage device 6, wherein:

[0034] Two flat plates 1 are arranged parallel to each other, and the upper flat plate 1 is provided with a mounting hole 11 for mounting to the bottom of the vehicle, and two opposite first vertical plates 3 and two opposite second vertical plates 4 form a side plate ;

[0035] The first vertical plate 3 includes a first outer plate 31 and a first inner plate 32, the first outer plate 31 and the first inner plate 32 are arranged in parallel, and the upper end and the lower end of the first outer plate 31 are respectively slidably connected to the two flat plates 1. The upper end and the lower end of the first inner plate 32 are slidably connected to the two flat plates 1 respe...

specific Embodiment 2

[0041] In Embodiment 1, since when the impact point is the junction of the first vertical plate 3 and the second vertical plate 4, and at the corner, the force on the first outer plate 31 or the second outer plate 41 is parallel to the plate surface, Then the linkage device 6 basically fails, and the first vertical plate 3 and the second vertical plate 4 are mainly bent and deformed, so it is still easy to cause damage to the internal battery pack. Therefore, on the basis of embodiment 2, as Figure 3 to Figure 4 As shown, the force component device 5 is also included in this embodiment. The force component device 5 includes a force-bearing piece 51 and a support member. The support member includes a force-bearing rod 52 and a connecting plate 53. The force-bearing rod 52 is fixedly connected to the connecting plate 53. The load-bearing piece 51 is arc-shaped, and both ends of the force-bearing piece 51 are provided with supports, and the two load-bearing rods 52 are respective...

specific Embodiment 3

[0044] In Embodiment 1 or Embodiment 2, when a continuous force impact occurs, the energy absorption of the device is too limited, and because the pin shaft 64 is generally low in shear strength, it is easy to occur when a slight impact occurs. broken, so that the replacement of pin shaft 64 is too frequent and unreasonable, so on the basis of embodiment 1 or embodiment 2, as Figure 1 to Figure 5 As shown, in this embodiment, an energy absorbing device 7 and a rubber pad 9 are also included. The material of the pin shaft 64 is aluminum 1050A. The energy absorbing device 7 includes a first clamp 71, a first connecting rod 72, an energy absorbing sheet 73, a first Two clamping plates 74 and second connecting rods 75, one end of the two first connecting rods 72 are respectively hinged to the first clamping plate 71, the other end of one first connecting rod 72 is hinged to one end of the energy-absorbing sheet 73, and the other end The other end of a connecting rod 72 is hinged ...

Abstract

The invention discloses a battery pack anti-collision reinforcing structure for a new energy automobile and belongs to the field of new energy auxiliary devices. Two first vertical plates and two second vertical plates form a side plate, a first outer plate and a first inner plate are connected with two flat plates, a second outer plate and a second inner plate are connected with the two flat plates, two ends of a connecting rod are fixedly connected with the two flat plates respectively, a transmission gear is rotatably connected with the connecting rod close to the flat plates, a first rackand a second rack are meshed with the transmission gear, a pin shaft penetrates through an end face of the transmission gear and is connected with a positioning hole, the first rack is connected withthe first outer plate or the second outer plate, and one end of the second rack is connected with the first inner plate or the second inner plate. When the pin shaft is violently impacted by externalforce, the pin shaft is broken, the transmission gear can rotate freely, the first outer plate or the second outer plate slides inwards, and the corresponding first inner plate or the second inner plate slides outwards, so most of energy can be counteracted, and the internal battery pack is protected.

Description

technical field [0001] The invention relates to the field of new energy auxiliary devices, in particular to an anti-collision reinforcement structure for a battery pack of a new energy vehicle. Background technique [0002] In the face of huge environmental protection pressure and severe energy forms around the world, in recent years, the world's major automobile producing countries have regarded the development of the new energy automobile industry as a major strategic measure for sustainable economic and social development. Industry is an inevitable choice in the era of low-carbon economy. At the same time, the industrial development of new energy vehicles will also be a new guide for the automotive industry. [0003] In order to ensure the cruising range, lithium-ion batteries are often used as power batteries for new energy vehicles due to their advantages of high voltage, large specific energy, and long cycle life; the current manufacturing process of lithium-ion batter...
