Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

A kind of ventilation adjustment device, comprising a ventilation column 1, a connecting column 2 sleeved outside the ventilation column 1, a ventilation plate 3 arranged at one end of the connecting column 2; the middle part of the ventilation plate 3 is provided with the The air inlet of the connection column 1 is provided with a plurality of exhaust holes 31 on the upper side of the ventilation tray 3; the side wall of the ventilation column 1 is provided with a plurality of ventilation holes 11, and the side wall of the connection column 2 is provided with matching The adjustment hole 21 of the ventilation hole 11; the lower part of the ventilation column 1 is rotatably connected with a choke door 4, the radial direction of the choke door 4 is provided with a rotating shaft 5, and the inner wall of the connecting column 2 is provided with a guide slot 6, the rotating shaft 5 passes through the side wall of the ventilation column 1, and fits in the guide slot 6.

Specifically, the two ends of the rotating shaft 5 are square-shaped, the guide groove 6 includes four wavy arc-shaped sub-slots, the joints of adjacent arc-shaped sub-slots are perpendicular to each other, and the side of the ventilation column 1 The wall is provided with a lifting channel 7 along its axial direction. The structure is a specific embodiment in which the rotating shaft cooperates with the guide groove, which clamps the two ends of the rotating shaft through the guiding groove, and the end of the rotating shaft gradually changes direction along the guiding groove, so that the choke valve is gradually turned over. Moreover, a horizontal connecting portion is provided between adjacent sub-grooves. The connecting portion is used to make the blocks at both ends of the rotating shaft be in a non-tilted state, and the choke door be in a horizontal or vertical state, that is, the choke door is in a fully opened or closed state.

In addition, the ventilation hole 11 on the ventilation column 1 and the adjustment hole 21 on the connecting column 2 are long holes along the circumference. The structure makes the adjustment range of the air outlet here larger. The diameter of the exhaust holes 31 on the ventilation tray 3 gradually increases from the center to the side of the ventilation tray 3 . Since the closer to the center of the ventilation disk, the wind speed is greater, so the aperture at this place is reduced, so that the air output of each location of the ventilation disk is equal, and the air circulation is more uniform.

Finally, the upper end of the ventilation column 1 is provided with a driven gear 7 , one side of the ventilation column 1 is provided with a driving motor 8 , and the output end of the driving motor 8 is provided with a driving gear 9 meshing with the driven gear 7 . The structure enables the adjustment operation to be automatically performed by driving the motor.

To sum up, the working mode of the ventilation column and the ventilation panel is as follows: the initial state is that the choke door is closed, and the ventilation hole on the ventilation column completely coincides with the adjustment hole on the connecting column, that is, only the air enters through the ventilation hole on the ventilation column, and the air The cycle rate is lower, which is suitable for slightly higher battery temperature. However, as the temperature becomes too high and the requirements cannot be met only through the above circulation method, the ventilation column is rotated at a certain angle according to the specific situation. At this time, the overlapping surface of the ventilation hole on the ventilation column and the adjustment hole on the connecting column is reduced. The air output here also decreases accordingly. At the same time, with the rotation of the ventilation column, the choke door is gradually turned over, that is, the air output at the ventilation pan gradually increases. Since there are more holes in the ventilation pan, and it circulates upward from the bottom of the battery box air, so its circulation effect is stronger; that is, when the ventilation column rotates, the air circulation effect in the entire battery box is improved until the choke door is in a vertical state, that is, fully opened, at this time the ventilation holes on the ventilation column are connected to the The adjustment holes of the column are in a completely staggered state, and the entire air circulation effect is optimal.

The above is only a preferred specific implementation of the utility model, which is an implementation based on the overall concept of the utility model, and the protection scope of the utility model is not limited thereto, anyone familiar with the utility model Any changes or replacements that can be easily conceived by those skilled in the technical field within the technical scope disclosed in the present utility model shall be covered by the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope of the claims.
