[0001] The utility model relates to the technical field of electric vehicle equipment, in particular to a heat dissipation mechanism of a double battery compartment of an electric vehicle. Background Art

[0002] The heavy-duty electric vehicle is an electric vehicle specially designed for transporting goods. It usually has a high load capacity and is equipped with a dual battery compartment to support a longer driving range and stronger power output. There are more groups of batteries in the dual battery compartment. Therefore, the electric vehicle needs to dissipate heat inside the dual battery compartment during driving. Currently, heat dissipation holes are usually opened on the side walls of the dual battery compartment to dissipate heat from the batteries inside. However, dust will enter the dual battery compartment through the heat dissipation holes, which may cause battery short circuit and malfunction over time. For this reason, we propose a heat dissipation mechanism for the dual battery compartment of an electric vehicle. Utility Model Content

[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Refer to the attached Figure 1-6 A heat dissipation mechanism for a dual battery compartment of an electric vehicle comprises a battery compartment body 1, a heat dissipation compartment body 2 is arranged on one side of the battery compartment body 1, and a vent 3 is arranged between the heat dissipation compartment body 2 and the battery compartment body 1, so that the interiors of the two compartments are interconnected to facilitate air circulation and heat dissipation;

[0028] Partitions 21 are symmetrically arranged in the heat dissipation chamber 2, and a filter cavity is formed between the partition 21 and the two side walls of the heat dissipation chamber 2. A filter component 24 is arranged in the filter cavity. An air inlet 22 connected to the filter cavity is provided on the side wall of the heat dissipation chamber 2. The opening side of the filter component 24 is arranged to fully surround one end of the air inlet 22. An air outlet 23 is provided on one side of the partition 21, so that the filter cavity is connected with the inner cavity of the heat dissipation chamber 2. Air enters the filter cavity through the air inlet 22, is filtered by the filter component 24, and then enters the heat dissipation chamber 2, and then enters the battery chamber 1 through the vent 3, so as to prevent dust from entering the battery chamber 1 and causing the internal battery to short-circuit and malfunction.

[0029] In this embodiment, the opening directions of the air outlet 23 and the air inlet 22 are set at 90 degrees. On the one hand, it prevents cold air from blowing directly into the battery compartment 1 in winter. On the other hand, when dust blocks the end of the filter component 24 away from the air inlet 22, it will not affect the air intake efficiency.

[0030] In this embodiment, the filter assembly 24 includes a plug plate 241, and an opening in the plug plate 241 is arranged to completely surround one end of the air inlet 22. A filter cylinder 242 is arranged on one side of the plug plate 241. A plurality of supporting springs are arranged inside the filter cylinder 242 along the cylindrical direction. A conical cylinder 243 with a larger upper part and a smaller lower part is arranged at the bottom of the filter cylinder 242. An ash storage cylinder 244 is arranged at the bottom of the conical cylinder 243. When the electric vehicle is driving, there will be a bumpy process. At this time, the filter cylinder 242 will vibrate, and the dust filtered in the filter cylinder 242 will fall into the ash storage cylinder 244 for storage through the conical cylinder 243. The conical cylinder 243 with a larger upper part and a smaller lower part can reduce the amount of dust that bounces back to the filter cylinder 242, thereby greatly extending the cleaning cycle of the filter assembly 24.

[0031] In this embodiment, the ash storage cylinder 244 is spherical, and the diameter of the interior of the ash storage cylinder 244 where it is connected to the conical cylinder 243 is smaller than the diameter of the middle part of the interior of the ash storage cylinder 244, which is convenient for storing dust and reduces the amount of dust rebounding into the filter cylinder 242.

[0032] In this embodiment, a sealing plate 245 is provided at the bottom of the plug plate 241, and slots 246 are provided on both sides of the sealing plate 245. A U-shaped slot 25 matching the plug plate 241 is provided in the heat dissipation chamber 2, and a mounting port 26 matching the sealing plate 245 is provided at the bottom of the heat dissipation chamber 2. Cards 27 matching the slot 246 are provided on both sides of the bottom of the mounting port 26. The filter assembly 24 is installed in the filter cavity through the mounting port 26. At this time, the plug plate 241 is inserted into the U-shaped slot 25, and the sealing plate 245 is inserted into the mounting port 26 to form a seal. At this time, the card plate 27 is stuck in the slot 246, so that the filter assembly 24 is fixed as a whole, which is convenient for the installation of the filter assembly 24.

[0033] In this embodiment, the card plate 27 includes an inclined plate portion 271 and a limiting portion 272. The limiting portion 272 is provided with a horizontal portion extending toward the slot 246. The inclined plate portion 271 is arranged at the bottom of the limiting portion 272 and is inclined toward the outside. When installed upward, the sealing plate 245 will push the inclined plate portion 271, so that the card plate 27 as a whole undergoes elastic deformation. After the filter assembly 24 is installed, the card plate 27 elastically resets so that the limiting portion 272 is stuck in the slot 246, and the horizontal portion of the limiting portion 272 abuts against the top of the slot 246, so that the sealing plate 245 is fixed. When disassembling, the inclined plate portion 271 is pulled to make the limiting portion 272 move out of the slot 246, and then the sealing plate 245 is pulled downward, so that the filter assembly 24 as a whole is taken out through the installation port 26, which is convenient for cleaning the filter cartridge 242, the conical cartridge 243 and the ash storage cartridge 244 inside the filter assembly 24.

[0034] In this embodiment, a plurality of limiting plates 28 are provided in the battery compartment body 1. The plurality of limiting plates 28 are rectangular devices, which facilitates the installation of electric fans and improves the heat dissipation efficiency.
