Description

Technical Field

[0001] The utility model relates to the technical field of power battery heat dissipation, in particular to a PACK box with a strong exhaust structure. Background Art

[0002] Battery PARK is widely used in new energy electric vehicles. The battery PACK system of electric vehicles uses a mechanical structure to connect many single cells in series, and connects to the microcontroller (MCU) of the electric vehicle through the battery management system (BMS) and communication frame of the battery PACK. In order not to occupy the precious space in the car, more and more power battery PACKs are installed in the PACK box, which can effectively protect the power battery. However, due to various electrochemical and physical changes in the cells in the PACK box during the charging and discharging process, a large amount of heat will be generated, especially the ear part as the connection end, which dissipates the most heat. If timely and effective heat dissipation is not taken, the power supply efficiency of the battery pack will decrease, and the charge and discharge cycle life of the battery pack will be sharply shortened.

[0003] The existing PACK box mainly dissipates heat by setting heat dissipation channels on both sides of its internal partition and setting ventilation holes connected to the heat dissipation channels on the side of the PACK box. However, the heat dissipation function of this heat dissipation structure is very limited, the air flow is poor, it is difficult to discharge the heat in the PACK box in time, and it is difficult to meet the cooling requirements of power batteries in high power and hot environments, and it cannot effectively solve the problem of excessive temperature during the power supply process of the battery pack.

[0004] For example, the Chinese patent CN210182442U discloses a PACK box with a strong exhaust structure, which realizes strong exhaust heat dissipation of the PACK box by setting an exhaust fan, greatly improving the heat dissipation performance of the entire box; the exhaust fan is installed at the air outlet, so that the gas can fully circulate in the heat dissipation duct and take away the heat, avoiding the energy waste caused by the air flow being blocked and dispersed due to the use of blowing heat dissipation, and the inability to effectively pass through the heat dissipation duct.

[0005] However, the PACK box body is not provided with a dustproof structure, so when air enters the PACK box body, a large amount of dust may enter the PACK box body.

[0006] For this reason, we urgently need to provide a PACK box with a dust-proof function and a strong exhaust structure. Utility Model Content

[0007] The purpose of the utility model is to provide a PACK box with a strong exhaust structure to solve the problem that the PACK box is not provided with a dustproof structure as proposed in the above background technology, so that a large amount of dust will enter the PACK box when air enters the PACK box.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a PACK box with a strong exhaust structure, comprising a PACK box and a strong exhaust fan, wherein the strong exhaust fan is fixedly connected to the inside of the right end of the PACK box, and the inside of the PACK box is connected with a protective mechanism, wherein the protective mechanism comprises a dustproof unit and a drying unit, wherein the dustproof unit is arranged at the front and rear sides of the inside of the PACK box, and the drying unit is arranged at the middle position of the top side of the inside of the PACK box.

[0009] The dustproof unit includes a fixing frame, a rectangular frame, a dustproof net, a baffle, a connecting plate, a first threaded rod and a cylinder. The fixing frame is fixedly connected to the front and rear sides of the inside of the PACK box, the rectangular frame is connected to the inside of the fixing frame, the dustproof net is fixedly connected to the inner side of the rectangular frame, the baffle is connected to the right end of the fixing frame, the connecting plate is fixedly connected to the upper and lower ends of the front side of the baffle, the first threaded rod is fixedly connected to the upper and lower ends of the front right side of the fixing frame, and the cylinder is connected to the outer end of the first threaded rod.

[0010] A further improvement is that an internal thread is provided on the inner side of the cylinder, a groove is provided at the middle position of the left end of the connecting plate, the outer side of the first threaded rod is slidably connected to the inner side of the groove, the outer side of the first threaded rod is threadedly connected to the inner side of the cylinder, and the rear end of the cylinder abuts against the front side of the connecting plate. Thus, after the baffle is placed on the right end of the fixing frame and the groove at the left end of the connecting plate slides to the outer end of the first threaded rod, the cylinder is threadedly connected to the outer side of the first threaded rod until the cylinder moves back to the front side of the connecting plate, the connecting plate is fixed to the front side of the right end of the fixing frame, and the baffle is fixed to the right end of the fixing frame.

[0011] A further improvement is that the upper and lower ends of the inner side of the fixing frame are provided with sliding grooves, the upper and lower ends of the outer side of the rectangular frame are slidably connected to the inner side of the sliding grooves, and the right side of the rectangular frame abuts against the left side of the baffle. Therefore, after the rectangular frame is slid to the inner side of the sliding groove inside the fixing frame, the baffle is fixed to the right end of the fixing frame, so that the rectangular frame and the dust screen can be fixed to the inside of the fixing frame.

[0012] A further improvement is that the drying unit includes a storage box, a sealing plate, a second threaded rod and a rotating handle, the storage box is fixedly connected to the middle position of the inner top end of the PACK box body, the sealing plate is connected to the front end of the storage box, the second threaded rod is connected to the middle position of the inner rear end of the sealing plate, and the rotating handle is fixedly connected to the right end of the second threaded rod.

[0013] A further improvement is that the front right end of the storage box is hinged to the front left end of the sealing plate through a hinge, a threaded hole is provided in the middle of the rear end of the sealing plate, and the outer side of the second threaded rod is threadedly connected to the inner side of the threaded hole. Thus, when the rotating handle is turned to drive the second threaded rod in the threaded hole to rotate, the second threaded rod can move relative to the sealing plate.

[0014] A further improvement is that a threaded groove is provided in the middle position behind the right end of the storage box, the outer side of the left end of the second threaded rod is threadedly connected to the inner side of the threaded groove, ventilation grooves are provided at equal intervals inside the storage box, and an activated carbon bag is stored inside the storage box. Therefore, after the sealing plate is rotated to the right end of the storage box, the second threaded rod is rotated and moved to the left by rotating the rotating handle until the left end of the second threaded rod is threadedly connected to the threaded groove, so that the sealing plate can be fixed to the right end of the storage box.

[0015] A further improvement is that a rubber pad is fixedly connected to the outer side of the rectangular frame, so that after the rectangular frame is fixed to the inside of the fixing frame, the rubber pad on the outer side of the rectangular frame contacts the inner side of the slide groove, so that the contact point between the fixing frame and the rectangular frame can be kept sealed, preventing the air entering the PACK box from entering the PACK box through the gap between the fixing frame and the rectangular frame without being filtered by the dustproof net.

[0016] In summary, the present application discloses a PACK box with a strong exhaust structure.

[0017] This technical solution enables the rectangular frame and the dust screen to be fixed to the inside of the fixing frame by sliding the rectangular frame to the inner side of the slide groove inside the fixing frame and then fixing the baffle to the right end of the fixing frame, so that the air entering the PACK box from the air inlet on the outer wall of the PACK box will be filtered and dust-removed by the dust screen.

[0018] Furthermore, after placing the activated carbon bag in the storage box, the sealing plate is rotated to the right end of the storage box, and the rotating handle is turned to drive the second threaded rod to rotate and move left at the same time, until the left end of the second threaded rod is threaded into the threaded groove, so that the sealing plate is fixed to the right end of the storage box, thereby fixing the activated carbon bag in the storage box and filtering the air entering the PACK box.
