Technical Field

[0001] The utility model relates to the technical field of new energy power batteries, in particular to a new energy power battery compartment. Background Art

[0002] As the global energy crisis and environmental problems become increasingly serious, new energy power battery technology has become an important direction for sustainable energy development. However, new energy power batteries generate a lot of heat during the charging and discharging process. If the heat is not managed properly, it may lead to battery performance degradation or even safety accidents.

[0003] Existing new energy power batteries conduct heat to a fixed device when in use, but the heat still exists on the fixed device and continues to be carried out uninterruptedly, causing the heat to accumulate on the outer surface and difficult to discharge, resulting in incomplete heat dissipation. In addition, when the vehicle performs sudden braking and other actions while moving, the battery will collide with the fixed device, easily causing battery damage. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a new energy power battery compartment, aiming to solve the problem of incomplete heat dissipation of the battery compartment in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A fixed box, wherein a top cover is provided on the top of the fixed box, and a battery assembly is arranged in the fixed box;

[0008] At least four buffer mechanisms are evenly spaced between the fixing box and the battery assembly;

[0009] Heat dissipation fins are arranged inside the fixed box;

[0010] The air guide component is arranged on a side of the fixed box opposite to the heat dissipation fins and is located outside the fixed box. The air guide component is connected to the heat dissipation fins through a heat dissipation pipe.

[0011] Furthermore, the air guide assembly includes:

[0012] A heat dissipation cover is arranged on a side of the fixed box opposite to the heat dissipation fins and is located outside the fixed box, and a plurality of air induction slots are provided on the heat dissipation cover;

[0014] Furthermore, the air guide assembly further includes:

[0015] A plurality of oblique air guide plates are arranged at intervals on a side of the heat dissipation cover away from the heat dissipation plate.

[0016] Furthermore, the buffer mechanism comprises:

[0017] An elastic member, one end of which is connected to the inner wall of the fixed box;

[0018] A connecting rod, hinged to the other end of the elastic member;

[0019] The top block is hinged to one end of the connecting rod away from the elastic member and abuts against the battery assembly.

[0020] Furthermore, the elastic member comprises:

[0021] A support spring, arranged on the inner wall of the fixed box;

[0022] The sliding block is connected to one end of the supporting spring away from the fixed box and is hinged to the connecting rod.

[0037] See also Figure 1-Figure 5The utility model provides a new energy power battery compartment, comprising: a fixed box 1, a buffer mechanism, a heat dissipation fin 34 and an air guide assembly. A top cover 11 is provided on the top of the fixed box 1, and a battery assembly 12 is arranged in the fixed box 1; at least four buffer mechanisms are arranged between the fixed box 1 and the battery assembly 12; the heat dissipation fin 34 is arranged on the inner side of the fixed box 1; the air guide assembly is arranged on the outer side of the fixed box 1; in the present application, by arranging the heat dissipation fin 34 on the inner wall of the fixed box 1, the heat generated during the charging and discharging of the internal battery assembly 12 can be absorbed, and the heat can be guided to the air guide assembly through the heat dissipation pipe 35, so as to realize the heat dissipation of the battery assembly 12 during the charging and discharging process. At the same time, the heat absorbed in the fixed box 1 is dissipated to the external air through the air guide assembly, so as to avoid the heat accumulation leading to the low heat dissipation efficiency of the heat dissipation fin 34, thereby improving the overall heat dissipation efficiency of the battery assembly 12; in addition, the battery is buffered and fixed by the buffer mechanism to avoid the direct collision between the battery assembly 12 and the inner wall of the fixed box 1 when shaking outside, thereby improving the safety of the battery assembly 12.

[0038] In the implementation of the present utility model, please refer to Figure 1 , Figure 2 and Figure 5 The air guide assembly is composed of a heat dissipation cover 3 and a heat dissipation plate 33. The heat dissipation cover 3 is arranged on a side of the fixed box 1 opposite to the heat dissipation fins 34 and is located on the outside of the fixed box 1, and a plurality of air induction grooves 32 are opened on the heat dissipation cover 3; the heat dissipation plate 33 is arranged in the heat dissipation cover 3 and is connected to the heat dissipation fins 34 through the heat dissipation pipes 35. By setting the air induction grooves 32, the external flowing wind can be guided into the heat dissipation cover 3 to dissipate the heat of the heat dissipation plate 33, and further the heat in the heat dissipation pipes 35 connected between the heat dissipation plate 33 and the heat dissipation fins 34 can be extracted, thereby improving the heat dissipation efficiency in the cabin and avoiding the accumulation of heat in the fixed box 1.

[0039] It should be noted that, in the embodiment of the present invention, the heat sink fins 34 are hollow inside and are loaded with coolant. When dissipating heat, the coolant absorbed by the heat sink fins 34 will be stored in the heat pipe 35, and the heat sink 33 absorbs the heat of the coolant in the heat pipe 35 and dissipates the heat to the outside through the air duct 32, thereby improving the heat dissipation efficiency.

[0040] In addition, a plurality of inclined air guide plates 31 are provided on the heat dissipation cover 3, and the plurality of inclined air guide plates 31 are evenly spaced and arranged on a side of the heat dissipation cover 3 away from the heat dissipation plate 33. In addition, the inclination angles of the inclined air guide plates 31 are not consistent, which can further guide the external cold air to flow into the heat dissipation cover 3, and guide the hot air after heat exchange to the outside of the heat dissipation cover 3 through the inclined air guide plates 31 with different inclination angles, forming an air flow, continuously cooling the heat dissipation plate 33 in the heat dissipation cover 3, and improving the heat dissipation efficiency.

[0041] In this example, see Figure 3 and Figure 4 The buffer mechanism includes an elastic member, a connecting rod 23, and a top block 24, one end of the elastic member is connected to the inner wall of the fixed box 1; the connecting rod 23 is hinged to the other end of the elastic member; the top block 24 is hinged to the end of the connecting rod 23 away from the elastic member, and abuts against the battery assembly 12. The battery assembly 12 is fixed in the fixed box 1 through the top block 24 to ensure the stability of the battery assembly 12 and avoid direct contact between the battery assembly 12 and the fixed box 1. The top block 24 is connected to the fixed box 1 through the connecting rod 23 and the elastic member to form a parallel buffer structure. When external shaking occurs, the force of the battery assembly 12 will be transmitted to the elastic member through the top block 24 to avoid collision between the battery assembly 12 and the battery box, thereby improving safety.

[0042] It should be noted that, in the embodiment of the utility model, a limiting slide groove 2 is provided in the fixed box 1, and the elastic member includes a support spring 21 and a sliding block 22. The support spring 21 is arranged in the limiting slide groove 2, and the sliding block 22 is connected to the end of the support spring 21 away from the fixed box 1, and is hinged to the connecting rod 23, and the sliding block 22 is in contact with the limiting slide groove 2. When the force of the battery assembly 12 is transmitted to the top block 24, the sliding block 22 can be driven to slide along the limiting slide groove 2 and be buffered by the support spring 21. At the same time, the support spring 21 can also provide a reverse impulse to reset the battery assembly 12, thereby further improving the safety of the battery assembly 12 and reducing the space occupied by the buffer mechanism.

[0043] As can be seen from the above, when the device is impacted by external force, the fixed box 1 will shake violently and greatly. When the fixed box 1 shakes, the battery assembly 12 will slide to both sides due to its own gravity. This force is transmitted from the top block 24 to the sliding block 22, driving the sliding block 22 to shake. The sliding block 22 slides outward under the action of the hinge rod and the support block, which will cause compression to the support spring 21. When the swing amplitude of one side of the fixed box 1 reaches the top, it will continue to swing in the opposite direction. At this time, the support spring 21 releases kinetic energy and pushes the sliding block 22 to reset the hinge rod and the support block. This repeated swinging can prevent the battery assembly 12 from being directly impacted. When the battery assembly 12 is working, a large amount of heat will be generated. The heat dissipation fins 34 will absorb the heat on the outside of the battery assembly 12, and then transmit it to the heat sink 33 through the transmission pipe. The structure of the oblique air guide plate 31 can attract external wind to cool the coolant in the heat sink 33, forming a heat dissipation cycle, improving the heat dissipation efficiency, and avoiding heat accumulation.
