Optionally, the plugs 142 on the body 141 are arranged at intervals (for example, two plugs are arranged in a row), and the arrangement is neat, so that the space is saved, and the overall appearance is good. In the embodiment of the present application, the connector 14 is used for connecting an external video capture device, and by providing the connector 14 with such a structure, each plug-in connector 142 can be accessed by at least one video capture device, so that the connector 14 can be used for connecting multiple video capture devices, and the number of accessible external devices and the convenience of access are improved.

As shown in fig. 1 and 2, in some embodiments, the housing 11 includes a base plate 111 and a mounting post 112. The mounting posts 112 are disposed on the bottom plate 111, and the mounting posts 112 are used for positioning and mounting the circuit board 13. Specifically, the mounting posts 112 are provided in plural according to the shape of the circuit board 13 and the mounting requirement, and are correspondingly provided at each corner of the circuit board 13, so as to meet the fixed mounting requirement of the circuit board 13. The boundary shape of the cross section of the mounting post 112 in the direction perpendicular to the height direction of the post body thereof may be a circular shape or a polygonal shape, etc. The mounting post 112 is fixedly connected to the base plate 111 at one end in the height direction thereof, and the mounting post 112 is fixedly connected to the circuit board 13 at the other end in the height direction thereof by the first fastening member 15. The first fastening member 15 is optionally a screw, and the fixed connection is convenient. By the arrangement, the circuit board 13 is supported by the mounting posts 112, and the mounting posts 112 have a certain height, so that the circuit board 13 can be prevented from directly contacting the bottom plate 111, a certain spacing distance is reserved between the circuit board 13 and the bottom plate 111, the heat dissipation of the circuit board 13 is facilitated, and the stability of the working performance is kept.

In some embodiments, a plurality of sheet-like structures may be disposed on the bottom of the bottom plate 111 (i.e., the other side opposite to the side to which the mounting posts 112 are connected), and each sheet-like structure is disposed at intervals and extends for a suitable length along the length direction or the width direction of the bottom plate 111; alternatively, a portion of the sheet-like structures extends in the length direction of the base plate 111, a portion of the sheet-like structures extends in the width direction of the base plate 111, and the sheet-like structures in both directions intersect each other perpendicularly or obliquely. The arrangement of each sheet structure increases the contact area with air, thereby being beneficial to heat dissipation.

As shown in fig. 1 and 2, in some embodiments, the housing 11 further includes a support post 114. The supporting columns 114 are disposed on the base plate 111, and are disposed at least at positions on the base plate 111 corresponding to the middle area of the circuit board 13. That is, the supporting posts 114 are provided at positions corresponding to at least the middle positions of the area regions of the circuit board 13 with reference to the mounted position of the circuit board 13. In particular, since the middle of the area of the circuit board 13 is where the force deformation is the most severe. Therefore, the supporting posts 114 can provide support for the circuit board 13, prevent the circuit board from being deformed due to pressure, and thus prevent the occurrence of abnormal circuit in the circuit board 13, and keep the working performance of the circuit board 13 stable. In practical applications, the number of the supporting pillars 114 to be installed is set according to practical application requirements, and is not limited herein. Meanwhile, the shape of the supporting column 114 is optionally the same as that of the mounting column 112, and the height of the supporting column 114 is kept the same as that of the mounting column 112, so that the circuit board 13 can be kept flat after being mounted.

As shown in fig. 2, in some embodiments, a through hole 131 is formed on the circuit board 13, and a first connection hole 115 is formed on the mounting post 112. Thus, the circuit board 13 can be fixed to the mounting posts 112 by inserting one end of the first fastening member 15 through the through hole 131 and fastening it in the first connection hole 115. When the first fastening member 15 is a screw, the first connection hole 115 may be a threaded hole, so that the first fastening member and the first connection hole can be fixed by threaded connection.

As shown in fig. 1 and 2, in some embodiments, the housing 11 may be configured to further include a top plate 117. The top plate 117 has first and second opposing surfaces 1171 and a heat dissipating structure 118 disposed on the first surface 1171. Specifically, the first surface 1171 is a surface away from the accommodating space, and the second surface is a surface facing the accommodating space. The first surface 1171 and the second surface may be planar or curved. The heat dissipation structure 118 is disposed on the first surface 1171, and the heat dissipation structure 118 increases a contact area with air, so as to facilitate heat dissipation of each heat generating component on the circuit board 13 and improve the working stability of each electrical component on the circuit board 13. In the assembly connection, it is possible to connect the bottom plate 111 and the top plate 117 so as to form a receiving space between the bottom plate 111 and the top plate 117. The receiving space may be formed by providing a cavity on the bottom plate 111 and/or the top plate 117, and forming the receiving space between the bottom plate 111 and the top plate 117 after the two are connected.

As shown in fig. 2, in some embodiments, since the bottom plate 111 and the top plate 117 have a large size in the length direction, in order to improve the connection between the bottom plate 111 and the top plate 117, a second connection hole 116 is formed in a middle position of at least one side edge in the length direction (Y direction in fig. 2) of the bottom plate 111, and a third connection hole 132 is formed in the circuit board 13 at a position corresponding to the second connection hole 116. The domain controller 1 further includes a second fastening member 16, and the second fastening member 16 passes through the second connection hole 116 and the third connection hole 132 and is connected to the top plate 117. In this arrangement, the second fastening member 16 is connected to the bottom plate 111 and the top plate 117 at the intermediate position in the longitudinal direction, and the bottom plate 111 and the top plate 117 after connection are less likely to be cracked at the position, thereby enabling reliable connection between the bottom plate 111 and the top plate 117. The second fastening member 16 may be configured as a screw, and the top plate 117 is provided with a screw hole capable of being coupled with the second fastening member 16. The second connecting hole 116 and the third connecting hole 132 may be through holes 131 through which the second fastening member 16 passes, or both the second connecting hole 116 and the third connecting hole 132 may be threaded holes capable of being connected with the second fastening member 16 in a matching manner. The second fastening member 16 is coupled to the threaded hole of the top plate 117 to fixedly connect the bottom plate 111 and the top plate 117.

In some embodiments, as shown in fig. 2, a sidewall 113 may be disposed on the periphery of the bottom plate 111, and the sidewall 113 has a closed ring structure. Thus, when the bottom plate 111 and the top plate 117 are connected, the side wall 113 encloses the space to form a receiving space.

As shown in fig. 2, in some embodiments, the domain controller 1 further comprises a heat conducting member 17. The heat-conducting member 17 is disposed in the accommodating space, and one end of the heat-conducting member 17 is brought into contact with the second surface, so that heat on the heat-conducting member 17 can be transferred to the top plate 117. And the other end of the heat conductive member 17 is in contact with the heat generating device on the circuit board 13 to be able to absorb heat generated on the heat generating device. The area of the heat conductive member 17 that can be in contact with the second surface and the area of the heat conductive member 17 that can be in contact with the heat generating device can be set larger to more rapidly transfer heat. For example, the heat-conducting member 17 is in contact with all positions of the second surface and/or all positions of the surface of the heat-generating device, and/or the ratio of the contact area of the heat-conducting member 17 with the second surface to the total area of the second surface is greater than a first preset threshold, and/or the ratio of the contact area of the heat-conducting member 17 with the heat-generating device to the total area of the surface of the heat-generating device is greater than a second preset threshold. Meanwhile, the heat conducting member 17 is attached to the second surface and/or the heat conducting member 17 is attached to the surface of the heating device, so that heat dissipation can be performed quickly and effectively.

In some embodiments, a thermal conductive adhesive layer may be further disposed between the thermal conductive member 17 and the heat generating device, and the thermal conductive adhesive layer fills a gap between the thermal conductive member 17 and the heat generating device, so as to achieve rapid heat conduction.

In some embodiments, the bottom plate 111, the top plate 117, and the heat sink can be made of aluminum alloy material, so that the domain controller not only has good thermal conductivity, but also has light weight and is easy to move.

In some embodiments, the heat dissipation structure 118 may be a plurality of grooves recessed toward the inside of the top plate 117, so as to increase the contact area with air. As shown in fig. 1 and 2, in the embodiment of the present application, heat dissipation structure 118 is configured to include a plurality of heat dissipation fins 1181, and heat dissipation fins 1181 are spaced apart from each other, and top ends of heat dissipation fins 1181 are flush. Specifically, the heat dissipation fins 1181 are spaced apart from each other, so that a gap for air to flow between two adjacent heat dissipation fins 1181 can be formed. Thereby increasing the contact area with the air and improving the heat dissipation efficiency of the heat dissipation fins 1181. The shape of each of the heat dissipation fins 1181 may be a straight strip shape or a curved shape, which is not limited herein. The first surface 1171 may include a planar portion and a non-planar portion connected to the planar portion, the non-planar portion is provided with the heat dissipation structure 118, the heat dissipation structure 118 includes a plurality of heat dissipation fins 1181 spaced apart from each other, and a top end of each heat dissipation fin 1181 is disposed to be flush with the planar portion of the first surface 1171, so that heat dissipation requirements can be met, and each heat dissipation fin 1181 does not protrude from the planar portion of the first surface 1171, so that the size of the top plate 117 is not increased, and the reduction of the overall volume of the product is facilitated. In addition, since the heat sink is provided in the form of "sinking", the material consumption in manufacturing the top plate 117 can be reduced, and the overall weight of the product can be further reduced.

As shown in fig. 2, each of the heat radiation fins 1181 is provided to extend in the width direction (X direction in fig. 2) of the first surface 1171. Here, the width direction of the first surface 1171 may be determined according to the shape of the first surface 1171, for example, in a state where the shape of the first surface 1171 is a rectangle, the width direction of the first surface 1171 is the width direction of the rectangle; in a state where the first surface 1171 is elliptical in shape, the width direction of the first surface 1171 is the minor axis direction of the ellipse; in a state where the shape of the first surface 1171 is another shape, the width direction of the first surface 1171 is a direction perpendicular to a direction of a line connecting two points on the first surface 1171 that are the longest in distance. In this way, under the condition that the area of the first surface 1171 is fixed, a relatively large number of heat dissipation fins 1181 with a determined surface area are arranged, so that a relatively large total heat dissipation area is obtained, and because the number of the heat dissipation fins 1181 is relatively large, the number of space gaps formed between adjacent heat dissipation fins 1181 is also large, so that the air is easy to flow, and therefore, the heat can be further transferred to the external environment quickly, and the heat dissipation efficiency of the heat dissipation fins 1181 is improved. Of course, it is understood that in other embodiments, each of the heat dissipation fins 1181 may extend along the length direction (Y direction in fig. 2) of the first surface 1171.

As shown in fig. 1 and 2, in some embodiments, the housing 11 further includes side panels 119, and the side panels 119 are fixedly attached to the periphery of the top panel 117. Specifically, one end of the side plate 119 is connected to the top plate 117, and the other end extends downward to be connected to the bottom plate 111 to form a receiving space. The side plate 119 may be a closed ring or a ring having a notch. Here, in a state where the side plate 119 has a notch, a connection joint or a connection interface may be provided at the notch so that the device in the accommodation chamber and the external device are conveniently connected through the connection joint or the connection interface. The free ends of the side plates 119 are connected with the bottom plate 111 to form an accommodating space. Here, the free end of the side plate 119 is an end of the side plate 119 away from the top plate 117. The side plate 119 is a side plate of the entire housing 11 or a part of the side plate of the entire housing 11 in a state where the side plate 119 is connected to the top plate 117.
