Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 to 7, an embodiment of the present invention provides an air duct assembly, which includes a baffle 1 and a base 2; wherein the content of the first and second substances,

the barrier 1 is mounted on the base 2 and forms a sealing member 3 at a junction, and the barrier 1 partitions the base 2 into a first mounting area 21 and a second mounting area 22.

In this embodiment, the first mounting area 21 is used for mounting components or devices related to heat dissipation that need to be dissipated, the second mounting area 22 is used for mounting other components that do not need to be dissipated, and in practical applications, the inside of the driver is usually provided with a fan 7 for dissipating heat of the components located in the first mounting area 21. In the prior art, the baffle plate 1 and the base 2 are connected in a surface-to-surface bonding manner, so that a gap is easily generated at a position where the baffle plate 1 is in contact with the base 2, and thus in a process of heat dissipation by the fan 7, impurities such as conductive dust in the first mounting region 21 may flow into the second mounting region 22 along with flowing gas, so that important electronic components in the second mounting region 22 are damaged.

Therefore, according to the air duct assembly provided by the embodiment, the sealing member 3 is formed at the contact position between the baffle plate 1 and the base 2 by designing the structures of the baffle plate 1 and the base 2, and the blocking effect of the sealing member 3 on the air flow is utilized to ensure that the conductive dust in the first mounting area 21 cannot damage important electronic components in the second mounting area 22 along with the fact that the ventilation air flow enters the second mounting area 22 from the gap between the baffle plate 1 and the base 2, so that the protection effect of the baffle plate 1 is effectively improved.

Further, referring to fig. 1, 2 and 7, in an exemplary embodiment, the baffle 1 comprises a blocking wall 14 for separating a first mounting area 21 and a second mounting area 22 and a bottom wall 15 connected to the blocking wall 14 on a first side.

In this embodiment, the bottom wall 15 is perpendicular to the blocking wall 14 and is matched with the base 2, and the bottom wall 15 provides a space for the arrangement of other structures on the baffle 1, and simultaneously, the matching effect between the baffle 1 and the base 2 is better.

Further, with reference to fig. 3 and 4, in an exemplary embodiment, the baffle 1 has a first contact surface 11, the base 2 has a second contact surface 23 in contact with the first contact surface 11, the sealing member 3 includes a protrusion 31 and a groove 32 cooperating with the protrusion 31; wherein, the protrusion 31 is disposed on the first contact surface 11, and the groove 32 is disposed on the second contact surface 23; alternatively, the recess 32 is provided on the first contact surface 11 and the protrusion 31 is provided on the second contact surface 23.

In this embodiment, after the assembly of the baffle 1 on the base 2, the protrusion 31 and the groove 32 are matched with each other, when the ventilation airflow in the first mounting region 21 flows in along the gap between the baffle 1 and the base 2, the airflow is blocked by the protrusion 31, and the airflow is difficult to flow to the second mounting region 22 beyond the protrusion 31, so that an effective blocking effect is generated on impurities such as conductive dust in the ventilation airflow, and it is ensured that the conductive dust in the first mounting region 21 cannot enter the second mounting region 22 along with the ventilation airflow from the gap between the baffle 1 and the base 2 to damage important electronic components in the second mounting region 22.

Further, referring to fig. 3 and 4, in an exemplary embodiment, the protrusion 31 and the groove 32 are both disposed adjacent to a contact edge between the first contact surface 11 and the second contact surface 23. Illustratively, the protrusion 31 and the groove 32 are provided at the upper edges of the first contact surface 11 and the second contact surface 23.

In the present embodiment, the protrusion 31 and the groove 32 may be disposed at the upper edges of the first contact surface 11 and the second contact surface 23, so that the protrusion 31 and the groove 32, which are engaged with each other, form a hook-shaped structure at the upper edge to fix the baffle plate 1 to the base plate 2, and at the same time, the tortuosity of the path through which the airflow passes is increased, so that the difficulty that the ventilation airflow in the first installation area 21 is to flow from the gap into the second installation area 22 through the path is increased, thereby further enhancing the blocking effect of the sealing member 3 on the airflow.

It should be noted that the projection 31 is not limited to the form illustrated in fig. 3 and 4. Referring to fig. 5, in another exemplary embodiment, when the boss portion of the base 2 on which the protrusion 31 is disposed is a thin-wall-shaped structure, the protrusion 31 is actually an upper edge of the thin wall, and the groove 32 can be matched with the upper edge of the thin wall to fix the baffle 1 on the base 2, so as to achieve the same technical effects as the previous embodiment, and the details are not repeated here.

Further, referring to fig. 6, in an exemplary embodiment, the baffle 1 is provided with a buckle 13, a corresponding position on the base 2 is provided with a buckling portion 24 matched with the buckle 13, and the buckle 13 is buckled on the buckling portion 24.

In the present embodiment, the number of the buckles 13 and the number of the buckling parts 24 are preferably two, and the baffle 1 is fixed on the base 2 by buckling the buckles 13 on the buckling parts 24. Meanwhile, the protrusion 31 and the groove 32 are arranged at the lower edges of the first contact surface 11 and the second contact surface 23, and the protrusion 31 and the groove 32 which are matched with each other form a hook-shaped structure at the lower edges, so that the tortuosity of a path through which the airflow flows is increased, the difficulty that the ventilation airflow in the first installation area 21 flows from a gap into the second installation area 22 through the path is increased, and the blocking effect of the sealing member 3 on the airflow is further enhanced.

Further, referring to fig. 7, the bottom wall 15 is opened with a receiving hole 151 for receiving the capacitor 9.

In the present embodiment, the capacitor 9 is disposed in the first mounting region 21 for ventilation and heat dissipation.

Further, referring to fig. 1, 2 and 7, in an exemplary embodiment, the air duct assembly further includes a hook 4 for receiving the cable 8, wherein the hook 4 is disposed on a side surface of the baffle plate 1 facing the second mounting area 22.

Generally, a brake resistor and a brake resistor terminal are usually disposed inside the driver, and since the brake resistor needs to dissipate heat, the brake resistor is usually disposed in the first mounting region 21; the braking resistor terminal does not need to dissipate heat and is sensitive and vulnerable, so the braking resistor terminal is usually arranged in the second mounting area 22, and in addition, the braking resistor and the braking resistor terminal are generally connected through a cable 8, and the cable 8 needs to pass through the baffle 1. Because the cable 8 is usually reserved a little long before being installed, after the conventional wiring method is completed, the redundant part of the cable 8 may touch the signal board and the signal element on the signal board due to warping, and because the signal element is extremely sensitive, the interference of the cable 8 may cause great interference to the signal sent by the signal board, and even damage the signal element.

Therefore, in the present embodiment, the hook 4 is disposed on the sidewall of the baffle 1 as the fulcrum of the cable 8, the hook 4 is preferably a hook with an upward opening and a narrow-top-wide-bottom opening, wherein the transverse distance of the narrow part of the opening of the clamping hook 4 is smaller than the wire diameter of the wire 8, the transverse distance of the wide part is equal to or slightly larger than the wire diameter of the wire 8, thus, the cable 8 can be embedded into the opening of the clamping hook 4 from the top down, the cable 8 is fixed at the wide part without falling out of the opening of the clamping hook 4 through the limiting function of the narrow part, the wiring direction of the cable 8 is controlled, an assembler can use the fulcrum function of the clamping hook 4 to straighten the redundant part of the cable 8 without warping, the straightened cable 8 can not touch the signal board and the signal element on the signal board, therefore, the stability of the signal sent by the signal board is ensured, and the reliability of the equipment is improved.

Further, referring to fig. 1, 2 and 7, in an exemplary embodiment, the sidewall of the baffle 1 is formed with a slot 12 for the cable 8 to pass through.

In the embodiment, the slot 12 is used for the cable 8 to pass through the baffle 1, and the cable 8 does not need to pass over the baffle 1, so that damage to a cable sheath due to the fact that the cable 8 is too large in turning amplitude and scratched by the edge of the baffle 1 is avoided, and the space above the baffle 1 does not need to be occupied. Preferably, the slot 12 is disposed adjacent to the hook 4, so that the cable 8 can pass through the slot 12 with a relatively gentle routing range and then reach the hook 4, and the smoothness and rationality of routing are ensured. The sectional shape and size of the slot 12 can be set according to the wire diameter of the cable 8, and this embodiment is not particularly limited.

Further, referring to fig. 1, in an exemplary embodiment, baffle 1 is a one-piece injection molded structure; and/or the base 2 is of an integrated die-casting structure.

In this embodiment, the integrated molding can reduce the manufacturing cost of the baffle plate 1 and the base 2. The baffle 1 is made of plastic materials such as ABS, PC/ABS and the like, and PC plastic is preferably selected in the embodiment, so that the baffle has good temperature resistance and mechanical property; the base 2 is made of die-casting aluminum alloy and has the advantages of light weight, high dimensional accuracy and the like. In practical applications, the materials of the baffle 1 and the base 2 can be selected according to practical situations, which is not specifically limited in this embodiment.

Correspondingly, referring to fig. 7, an embodiment of the present invention further provides a driver, including a first component module 5, a second component module 6, a fan 7, and an air duct assembly in any of the above embodiments; wherein the content of the first and second substances,

the first component module 5 is mounted in the first mounting region 21, the second component module 6 is mounted in the second mounting region 22, and the fan 7 is mounted on the base 2 and disposed toward the first mounting region 21.

In this embodiment, the first component module 5 is a component or a device related to heat dissipation that needs heat dissipation, the second component module 6 is another component that does not need heat dissipation, and the fan 7 is used to ventilate the first installation area 21 so as to discharge high-temperature air in the first installation area 21 to the outside and supplement normal-temperature air to the first installation area 21, thereby achieving the heat dissipation effect.
