In some embodiments, as shown in fig. 1, the electrical device 100 may generally include a housing 102, a circuit board 104, an air outlet 106, an air inlet 108, a baffle 110, a heat sink 128, and the like. The electric device 100 shown in fig. 1 may be various types of electric devices 100. For example, in some embodiments, the electrical device 100 may be a servo drive. The electrical device 100 is shown in the position of the working state in fig. 1. A circuit board 104 is disposed within the housing 102 extending from the bottom to the top of the electrical device 100. The electronic components having a large heat generation amount at the lower portion of the circuit board 104 are fixed to the heat sink 128, and rapid heat dissipation is achieved by the heat sink 128. The electronic device on the upper part has small heat productivity and can dissipate heat mainly in an air convection mode. Convection is achieved by air flowing between the intake vent 108 and the exhaust vent 106.

In some embodiments, the air outlet 106 may be disposed proximate a top side of the housing 102. For example, the air outlet 106 may be disposed at or near the top of the electrical device 100. The intake vent 108 may be disposed on the housing 102 at a location below the outlet vent 106. For example, on a side or bottom surface of the housing 102. A through air duct is arranged between the air inlet 108 and the air outlet 106. In some embodiments, as shown in fig. 1, 3, and 4, the intake vent 108 may be disposed at a position above the middle of the electrical device 100. The intake opening 108 is disposed opposite to the outlet opening 106, i.e., the intake opening 108 faces the top side, facing the outlet opening 106. With this arrangement, air convection is facilitated, thereby accelerating heat dissipation from heat generating devices on the circuit board 104. As shown in FIG. 4, the intake vent 108 may include a plurality of unit intake vents. For example, the intake vent 108 may be divided into a plurality of unit intake vents by ribs of the heat sink 128. Embodiments of the present disclosure are not limited thereto, and the intake vent 108 may also be in other forms. The size of the intake vent 108 may be appropriately designed so that foreign substances falling from the intake vent 106 can be smoothly discharged from the intake vent 108.

In some embodiments, as shown in fig. 1, a baffle 110 may be positioned between the circuit board 104 and the air duct and extend from the air outlet 106 to the air inlet 108, and the baffle 110 may have vents 118 disposed thereon. As shown in FIG. 1, the baffle 110 extends from a first edge 130 of the intake vent 108 to a second edge 132 of the exhaust vent 106. In this manner, the circuit board 104 can be isolated from harmful foreign objects that enter the housing 102 of the electrical device 100 from the air outlet 106, such that the entering foreign objects fall out of the housing 102 from the air inlet 108. Foreign matter is prevented from falling onto the circuit board 104, thereby preventing the circuit board 104 from being short-circuited.

As shown in fig. 2, the outlet openings are shown as a plurality of openings in a dashed box indicated by reference numeral 106. The size of the opening on the right side in the figure is larger than the size of the opening on the left side. Since two circuit boards 104 are arranged side by side near the left side, more space is occupied, and the size of the opening near the left side is reduced accordingly. The shape of the outlet port 106 shown in fig. 2 is merely illustrative, and the shape of the outlet port 106 according to the embodiment of the present disclosure is not limited thereto, but may be variously changed. The shape and size of the outlet vents 106 may be adjusted accordingly depending on the shape, size, and location of the circuit board 104 within the housing 102. For example, the shape of the outlet vent 106 may be generally rectangular, rather than L-shaped as shown in fig. 2. The outlet 106 may have any other shape according to practical requirements. In some embodiments, the outlet vent 106 may be divided into multiple unit outlets. For example, the rib of the heat sink 128 divides the unit outlet into a plurality of unit outlets. Each unit outlet is sized so that the airflow through the outlet 106 is sufficient to dissipate the heat generated by the circuit board 104. Compared with the known dust screen, the size of each unit air outlet is larger, so that heat dissipation is facilitated.

In some embodiments, as shown in FIG. 3, the heat sink 128 is exposed, and thus the heat sink 128 may be part of the housing 102. In some embodiments, the heat sink 128 is not exposed, but is disposed inside the housing 102. Different designs or combinations can be carried out according to actual needs.

During operation or maintenance of the electrical apparatus 100, an operator may inadvertently drop some foreign object, such as a small part or tool, into the housing 102 through the outlet vent 106. If the foreign object is a conductor such as metal, it may cause a short circuit of electronic devices on the circuit board 104, causing a danger. In the embodiments of the present disclosure, such a short circuit event can be prevented by providing a baffle 110 between the circuit board 104 and the air duct. The fallen foreign objects may fall directly out of the housing 102 from the intake vent 108 or may fall out of the housing 102 from the intake vent 108 down the wall of the baffle 110. According to the scheme of the embodiment of the disclosure, the dust screen does not need to be added, so that the dust screen is not required to be cleaned or replaced. Thus reducing costs and saving time.

The baffle 110 of the disclosed embodiment is described below in conjunction with fig. 5. Fig. 5 shows a schematic view of a baffle 110 mounted within the housing 102 of the electrical device 100, according to one embodiment of the present disclosure. As shown in fig. 5, the baffle 110 is secured within the housing 102. The baffle 110 may further include a fixing hole, and the fixing hole may be provided on the body part 112. For example, may be provided at the edge of the baffle 110. The baffle 110 may be secured to the housing 102 or to the heat sink 128 within the housing 102 by threaded fasteners. In the above embodiment, the retainer 110 can be reliably fixed by the snap 122 and the screw fixing.

In some embodiments, as shown in fig. 5, the baffle 110 may also be provided with a device aperture 120. The device hole 120 may be provided at a position corresponding to a device having a larger size and having an insulating case protruding on the circuit board 104. The device apertures 120 allow the protruding devices to pass through the respective device apertures 120. The device aperture 120 may be sized to match the device, i.e., the dimensions of the two coincide.

In the above embodiment, the device hole 120 is provided in the barrier 110, so that a device having a larger size and having an insulating housing can pass through the device hole 120 in the barrier 110. The shield 110 may be free from inadvertent clearance from components on the circuit board 104, since even a conductor such as metal may fall onto components of the insulative housing without causing a short circuit. In this way, flexibility in design is increased.

Shown at 140 in fig. 5 are threaded holes for securing the circuit board 104, through which the circuit board 104 may be secured. Reference posts 142 are shown in fig. 5, and the reference posts 142 may be located on the heat sink 128 or on the housing 102 for positioning the circuit board 104. Shown at 144 in fig. 5 as a threaded hole, the threaded hole 144 may be located on the heat sink 128 or on the housing 102 and may be used to secure another circuit board. In some embodiments, the baffle 110 is disposed adjacent to the circuit board 104 to easily shield the circuit board 104 from foreign objects that may fall onto the circuit board 104 and cause a short circuit.

In some embodiments, the baffle 110 may also be coupled to the circuit board 104. For example, the bezel 110 and the circuit board 104 may be coupled together by fixing posts. The fixing column can be provided with a threaded hole, and the fixing column and the threaded hole can be fastened through screws. In some embodiments, similar to being secured to the circuit board 104, the baffle 110 may also be coupled to a heat sink 128 of the electrical device 100. In the above embodiments, the baffle 110 may be coupled to the circuit board 104 or the heat sink 128 of the electrical device 100 as required by the actual design, increasing design flexibility.

The structure of the baffle 110 is further described below in conjunction with fig. 6-9. Fig. 6 illustrates a perspective view of the baffle 110 of the electrical device 100, according to one embodiment of the present disclosure. Fig. 7 illustrates a rear view of the baffle 110 of the electrical device 100, according to one embodiment of the present disclosure. Fig. 8 illustrates a front view of the baffle 110 of the electrical device 100, according to one embodiment of the present disclosure. Fig. 9 illustrates a top view of the baffle 110 of the electrical device 100, according to one embodiment of the present disclosure.

In some embodiments, as shown in fig. 6, the baffle 110 may include a main body portion 112 and a bent portion 116. The bent portion 116 may extend from the main body portion 112 at a first angle. In the embodiment shown in fig. 6, the main body portion 112 of the baffle 110 may include left and right portions that are not in the same plane, as further shown in fig. 9. Embodiments of the present disclosure are not so limited. In some embodiments, the body portions 112 may lie in the same plane. The shape of the body portion 112 may vary depending on the shape, location, etc. and other configurations of the circuit board 104 within the housing 102.

In some embodiments, the bent part 116 may extend to the side of the housing 102, i.e., the edge of the bent part 116 abuts against the side of the housing 102. The boundary line 114 of the main portion 112 adjacent to the bent portion 116 extends toward the first edge 130 of the air inlet 108. The abutting edge of the lower side edge of the main body portion 112 and the bent portion 116 may surround the edge of the air inlet 108. Thereby shielding the circuit board 104. It is ensured that the foreign matter falling into the housing 102 from the air outlet 106 falls out of the air inlet 108 directly or falls out of the housing 102 along the surface of the bent portion 116 after falling into the bent portion 116. Therefore, the circuit board 104 is prevented from being short-circuited or otherwise damaged due to foreign matters falling into the housing 102 from the air outlet 106 falling onto the circuit board 104 or being ejected onto the circuit board 104 by colliding with the inner side wall of the housing 102.

In some embodiments, the main body portion 112 extends to the top side along the first direction X, and the bent portion 116 extends to the side of the housing 102 along the second direction Y perpendicular to the first direction X. In this way, shielding of the circuit board 104 can be achieved with a simple structure, preventing occurrence of short circuits.

In some embodiments, the body portion 112 is a planar structure. In the above embodiment, the main body 112 is configured to be a planar structure, and is matched with the bending portion 116, so as to achieve a shielding effect on the circuit board 104.

In some embodiments, the main body 112 may also be a curved structure. The curved structure extends between the air outlet 106 and the air inlet 108, and the edge of the curved structure located inside the housing 102 extends to the side of the housing 102. The shielding of the circuit board 104 can also be achieved by providing the main body portion 112 with a curved surface structure without separately combining with the bent portion 116. In this way, the designer can make an appropriate choice according to actual needs.

In some embodiments, a snap 122 is provided on the baffle 110. As shown in fig. 6, the catch 122 may be disposed at an edge of the body portion 112. The clips 122 are adapted to snap into corresponding card slots on the housing 102. In some embodiments, it may be necessary to rotate a certain angle for installation due to the structure of the catch 122 and the corresponding slot on the housing 102. Thus, after installation in place, there may be some clearance in the direction perpendicular to the baffle 110. To avoid the baffle 110 from wobbling in the gap direction, in some embodiments, as shown in fig. 6, a support plate 126 may also be disposed on the circuit board 104. After the baffle 110 is snapped onto the housing 102 via the snap 122, the baffle 110 may be further supported by the support plate 126 in a direction perpendicular to the body portion 112 of the baffle 110, thereby ensuring that the baffle 110 is securely fastened to the housing 102. In some embodiments, the baffle 110 may be disposed in one of the heat sink teeth of the heat sink 128, and the edge of the baffle 110 may be pointed at a predetermined location within the heat sink tooth. This serves to support the baffle 110 without additional space within the housing 102.

In some embodiments, as shown in fig. 6-8, the baffle 110 is provided with vents 118. The number of vents 118 may be set as much as possible to ensure adequate air circulation. In addition, the size of the vent may be selected to avoid foreign objects that may fall from the air intake 108 into the housing 102 from falling through the vent 118 onto the circuit board 104 due to the vent 118 being too large.

In some embodiments, referring to fig. 2 and 3, the size of the outlet vent 106 may be larger than the size of the inlet vent 108. The size of the air outlet 106 is larger than that of the air inlet 108, so that heat can be dissipated as soon as possible. Accordingly, the baffle 110 may have a size that decreases from the outlet vent 106 to the inlet vent 108. As shown in fig. 6 to 8, the size of the baffle 110 gradually decreases from top to bottom along the boundary line 114 between the main body portion 112 and the bent portion 116. Eventually, the edge of the lower portion of the baffle 110 mates with the edge of the intake vent 108. In the above embodiment, by making the baffle 110 have a size that decreases from the outlet 106 to the inlet 108, the shape and size of the baffle 110 can be matched to the passage between the outlet 106 and the inlet 108, thereby ensuring effective isolation of foreign objects entering the housing 102 from the outlet 106.

In some embodiments, the baffle 110 is an injection molded unitary structure. By forming the baffle 110 as an integral structure by means of injection molding, manufacturing and mounting processes can be simplified, and reliability of the baffle 110 can be enhanced.

In the above embodiments of the present disclosure, it is mainly described that the baffle 110 can prevent the conductors (e.g., metal parts, small tools, etc.) falling from the air outlet 106 from contacting the circuit board 104 by foreign matters, thereby causing a short circuit. Embodiments of the present disclosure are not limited thereto, and for foreign objects such as non-conductors, if the foreign objects are above a predetermined size, the foreign objects can be prevented from falling into the housing 102 and contacting the circuit board 104. Even for foreign matter below a predetermined size, the possibility of contact with the circuit board 104 through the hole in the shutter 110 can be at least reduced. Thereby avoiding or reducing damage to the circuit board 104 circuitry or electronic components.

According to the scheme of the embodiment of the disclosure, the baffle is arranged between the circuit board and the air channel, so that the circuit board is separated from the air outlet, and therefore, foreign matters are prevented from entering the shell with a simple structure, and short circuit is caused to circuits or electronic devices in the shell, particularly on the circuit board. Thereby improving the safety and reliability of the device. In addition, the scheme of the embodiment of the disclosure can prevent the short circuit, and can also prevent other damages of the circuit board caused by foreign matters, such as mechanical damage caused by collision. In addition, the accumulation of foreign matters such as dust at the air outlet can be reduced.
