Example Embodiment

[0020] Example 1

[0021] Such as Figure 1-2 As shown, the present invention provides a vehicle-use lithium battery pack fixing device, including a battery box 1 and a lithium battery 5. The battery box 1 is composed of an outer box 2 and an inner box 3. The battery box 1 is equipped with several evenly arranged Lithium battery 5, both sides of the battery box 1 are provided with vents 9 and a number of wiring ports 8, a shock-absorbing interlayer 4 is provided between the outer box 2 and the inner box 3, and a temperature sensor 7 is installed on one side of the lithium battery 5 , A cooling fan 10 is installed inside the vent 9.

[0022] Please refer to image 3 There are several C-shaped cavities in the shock-absorbing sandwich layer 4. The cavity is formed by the intersection of the outer plate 5 and the C-shaped inner support plate 6. In this embodiment, the bending directions of the cavities are consistent. Among them, the force deflection curve of the support structure ...

Abstract

The invention discloses a vehicle lithium battery pack fixing device. The vehicle lithium battery pack fixing device comprises a battery box and lithium batteries, wherein the battery box comprises an outer box and an inner box, a plurality of lithium batteries are arranged in the battery box and are uniformly arranged, ventilation heat dissipation holes and a plurality of wiring holes are arranged in both of two sides of the battery box, a shock absorption sandwiched layer is arranged between the outer box and the inner box, a temperature sensor is arranged at one side of each lithium battery, and heat dissipation fans are arranged in the ventilation heat dissipation holes. The shock absorption sandwiched layer is arranged in the device, the shock of a lithium battery pack during the travelling process of a vehicle can be substantially reduced, the lithium battery pack is effectively protected, the service lifetime of the battery pack is prolonged, and the safety of the battery pack is improved; and moreover, the temperature sensor is arranged in the battery box, the heat dissipation fans are arranged at two ends of the battery box, the temperature sensor and the heat dissipation fans are in control connection with a vehicle central control system, intelligent and automatic heat dissipation can be achieved, the temperature of the lithium battery pack is reduced, and excessively high temperature of the battery pack due to long-term working is prevented.

Description

technical field [0001] The invention relates to a fixing device, in particular to a fixing device for a lithium battery pack used in a vehicle. Background technique [0002] Lithium batteries refer to batteries containing lithium (including metal lithium, lithium alloys, lithium ions, and lithium polymers) in the electrochemical system. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metallic lithium and are rechargeable. Lithium metal batteries, the fifth generation of rechargeable batteries, were born in 1996, and their safety, specific capacity, self-discharge rate and performance-price ratio are superior to lithium-ion batteries. Due to its own high technical requirements, only a few companies in a few countries are producing such lithium metal batteries. Since the emergence of smart phones in 2007, followed by tablet computers, the world has entered the era of intelligenc...
