FIG. 6 is a schematic diagram of a local structure of a housing member in the center board unit provided in the first embodiment of the present invention. As shown in FIGS. 1 to 6, specifically, the center board unit provided in this embodiment includes a housing assembly 1, a connector assembly 2 fixed on the housing assembly 1, and a housing assembly 1. A plurality of electronic components are provided on the circuit board 3, including a circuit board 3 sealed inside, and the connector assembly 3 is electrically connected to the electronic components.

Specifically, the centerboard unit can be applied in unmanned aerial vehicles or other equipment. In this embodiment, the application of the center board unit in an unmanned aerial vehicle will be described as an example. In order to control the load on the unmanned aerial vehicle and the unmanned aerial vehicle, a flight control device, an avionics device, etc. are provided on the unmanned aerial vehicle, thereby controlling the power system, the load, and various sensors on the unmanned aerial vehicle. Can ensure normal flight and operation of unmanned aerial vehicles. Among them, a power system or the like needs to provide a power supply signal having a high voltage value and a large current, but a sensor and various control devices require a power supply signal having a small voltage value and a small current. Therefore, in order to realize power supply and communication connection to devices having different demands, the center board unit includes a circuit board 3, and the circuit board 3 is connected to an avionics system of an unmanned aerial vehicle, a flight control device, or the like. , Achieves the provision of power sources of different standards for avionics systems or flight control devices, and realizes functions such as internal communication or external communication of unmanned aerial vehicles, thereby normally performing avionics systems or flight control devices, etc. Make it work, issue commands to power packages or loads on the unmanned aerial vehicle, and have the unmanned aerial vehicle perform flight operations or other tasks. The connector assembly 2 can be used to connect the circuit board 3 and other devices on the unmanned aerial vehicle to make electrical connections and signal exchanges between the circuit board 3 and the other devices.

The circuit board 3 includes a plurality of electronic components in order to realize functions such as power distribution and communication connection to the system of the unmanned aerial vehicle. The circuit board 3 protects and shields these electronic components. The centerboard unit further includes a housing assembly 1 so that it is not affected by the external environment. The housing assembly 1 has a case-like structure having a hollow cavity inside, and the circuit board 3 can be housed inside the housing assembly 1, and the housing assembly 1 is located outside the circuit board 3. A sealing structure is formed to prevent external dust, water droplets and other foreign matter from entering the housing assembly 1 so that the circuit board 3 can obtain good sealing protection. At this time, the connector assembly 2 is also fixed on the housing assembly 1, and by forming an electrical connection between the housing assembly 1 and the circuit board 3, a normal signal is generated between the circuit board 3 and the outside. Guarantee that transmission can be performed. In this way, the overall dimensions of the centerboard unit are made compact and the overall structure is improved.

A plurality of electronic components on the circuit board 3 include at least one of a capacitor, an electronic switch, and a control chip to optionally perform tasks such as electrical connection and signal transmission of the circuit board 3. Such circuit boards 3 can use different combinations between capacitors, electronic switches and control chips to meet power distribution and communication requirements for different components.

Among them, the circuit board 3 is usually a printed circuit board (Printed circuit board, PCB), and may be another type of circuit board. The number of circuit boards 3 may be one or plural.

In order to connect the circuit board 3 and the housing assembly 1, the circuit board 3 can generally be connected to the housing assembly 1 via a thread fastening member. In this way, the attachment / detachment and maintenance of the circuit board 3 becomes convenient.

As a selectable embodiment, the housing assembly 1 includes at least two housing members that can be joined together, and at least two housings, so that the circuit board 3 can be conveniently accommodated therein. After joining, the members jointly enclose a hollow cavity for accommodating the circuit board 3. At this time, the different housing members become walls of different parts of the hollow cavity, and the circuit board is jointly surrounded therein to form protection.

Generally, at least two housing members surrounding the hollow cavity are usually detachably connected so that the circuit board 3 can be conveniently taken out and inserted. In this way, one or more of the housing members are removed from the housing assembly 1, the opening through which the circuit board 3 can be taken out or inserted is exposed, and the circuit board 3 is placed in the hollow cavity. Alternatively, it is convenient to remove it from the hollow cavity, which makes it easier to inspect and replace the circuit board 3 in the centerboard unit.

Further, at least two housing members may be fixed by an engagement connection method or may be connected by a fastening member. Among them, the fastening member may be a screw thread fastening member, and a fixing structure such as a screw hole for providing the screw thread fastening member may be provided on the housing member.

As one selectable structure, the plurality of housing members may include a first housing member 1a and a second housing member 1b. In this way, the first housing member 1a and the second housing member 1b can be jointly joined to form a hollow cavity, and the number of housing members is small, so that the overall structure is good. And the connection is secure.

Further, the first housing member 1a and the second housing member 1b are generally joined from both sides of the circuit board 3 in the plate surface direction to form a hollow cavity. At this time, the first housing member 1a and the second housing member 1b are located on both the upper and lower sides of the circuit board 3, respectively, and are surrounded by the first housing member 1a and the second housing member 1b. The circuit board 3 is placed inside the hollow cavity. In this way, the hollow cavity formed by the housing assembly 1 corresponds to the shape of the circuit board 3, and the housing assembly 1 becomes compact.

Since the hollow cavity of the housing assembly 1 is formed by joining a plurality of housing members to each other, the seams and gaps between adjacent housing members are sealed and protected in order to guarantee the sealing performance of the hollow cavity. Should be. Therefore, in the center board unit, a first sealing member 4 provided at a joint between adjacent housing members among at least two housing members and used for sealing the hollow cavity can be selected. Further may be included. Specifically, the number of the first sealing members 4 can be provided according to the number of housing members. For example, when the housing assembly 1 has only two housing members, there is only one seam between adjacent housing members. In this case, if one first sealing member 4 is provided, The hollow cavity can be sealed. When the number of housing members in the housing assembly 1 exceeds two, the number of seams formed between adjacent housing members also becomes plural, and in this case, the first sealing having a complicated shape. One member 4 may be filled in all the seams, or different seams may be sealed by the first plurality of sealing members 4.

Further, in general, since the seam or gap formed between the adjacent housing members has a closed shape, the first sealing member 4 is provided with good sealing performance in order to give the first sealing member 4 good sealing performance. May be a seal ring. Since the shape of the seal ring is a closed ring, a closed shape without openings or breaks is formed at the seam, whereby the seam can be sealed.

The first sealing member 4 may be a rubber seal ring or a silicone rubber seal ring so that the first sealing member 4 can selectively form a good seal. In this way, by pressing between the adjacent housing members, the first sealing member 4 is deformed, and the first sealing member 4 is filled in the seam between the adjacent housing members to form the housing. The members can be brought into close contact with each other, and the hollow cavity made of the housing member can be made to have good airtightness or watertightness.

Further, the adjacent housing members may be sealed by other methods such as applying a sealing material to the joints of the housing members or wrapping a waterproof tape or a sealing film on the outside of the housing members. Well, or other sealing methods often used by those skilled in the art may be used, but are not described in detail here.

A large amount of heat is released from the electronic components on the circuit board 3 during operation, but since the housing assembly seals the circuit board 3 in the hollow cavity, the circuit board 3 is subjected to a convection method. It cannot be cooled, and after the circuit board 3 operates for a long time, heat accumulates and normal operation cannot be performed, which may cause damage. In order to dissipate heat to the circuit board 3, heat conduction is provided between the housing assembly 1 and the circuit board 3. In this way, the circuit board 3 can maintain normal operation by transferring heat to the housing assembly 1 by a conduction method and avoiding the phenomenon that its own heat accumulates.

In order to form a heat conduction path having good heat conduction between the housing assembly 1 and the circuit board 3, one selectable structure is for conducting heat on the circuit board 3 to the housing assembly 1. The conducting portion 11 is provided on the inner wall of the hollow cavity. In this way, heat can be transferred between the circuit board 3 and the housing assembly 1 by using the conductive portion 11 as a heat conductive medium.

Specifically, the first end of the conduction portion 11 is connected to the inner wall of at least one housing member, and has heat conduction between the second end of the conduction portion 11 and the circuit board 3. In this way, the heat generated in the circuit board 3 is directly transmitted to the housing member via the conduction portion 11, and is discharged from the housing member to the outside of the housing assembly 1. The conducting portion 11 may be connected to one housing member or may be connected to a plurality of housing members to conduct the heat of the circuit board 3 to a plurality of different housing members.

Here, as one selectable aspect, in order to simplify the structure of the conducting portion 11, the first end of the conducting portion 11 is connected to the inner wall of one housing member. As described above, the conduction portion 11 may have a protrusion or pillar shape having a simple structure so that it can be used to support the circuit board 3. In general, the number of conduction portions 11 may be one or a plurality, and different conduction portions may be connected to correspond to different housing members.

Further, the conduction portion 11 and the housing member may have an integrated structure. The conduction portion 11 and the housing member may be formed by using an integral molding method so that the heat of the conduction portion 11 is directly transferred to the main body of the housing member, and thus the conduction portion 11 and the housing member may be formed. The heat conduction efficiency with the main body of the member may be increased.

Since the heat source in the circuit board 3 is mainly an electronic component, the second end of the conducting portion 11 is made to have heat conduction directly with the electronic component on the circuit board 3 so as to be selectable. May be good. In this way, the heat on the electronic component is directly transferred to the housing assembly 1 via the conduction portion 11, and the heat dissipation efficiency of the circuit board 3 is increased.

Specifically, there may be a plurality of different heat conduction methods between the conduction unit 11 and the electronic component. For example, in one selectable embodiment, the second end of the conduction portion 11 comes into direct contact with an electronic component on the circuit board 3. At this time, in order to increase the heat conduction efficiency between the conductive portion 11 and the electronic component, a large contact surface is provided between the second end of the conductive portion 11 and the electronic component, and the space between the conductive portion 11 and the electronic component is provided. Should be guaranteed to be in close contact.

When the second end of the conduction portion 11 and the electronic component on the circuit board 3 come into direct contact, the surface of the end portion of the conduction portion 11 is rough, or the mounting accuracy between the housing assembly 1 and the circuit board 3 Due to such reasons, the heat conduction efficiency between the second end of the conducting portion 11 and the electronic component may be lowered. In order to form high thermal conductivity efficiency, as another selectable embodiment, the second end of the conductive portion 11 and the electronic component on the circuit board 3 may be connected by a thermally conductive medium. .. In general, since the heat conductive medium is usually a semi-solid or a liquid, it makes sufficient contact with the surface of the conductive portion 11 and the electronic component, and forms a good thermal conductive path between the conductive portion 11 and the electronic component. , Heat conduction velocity and heat conduction efficiency can be increased.

Specifically, the thermal conductive medium having a thermal conductivity rate and a thermal conductivity efficiency may generally be a thermally conductive adhesive or a thermally conductive grease, for example, a thermally conductive silicon grease or the like.

In this way, the heat generated on the circuit board 3 can be conducted to the housing member of the housing assembly 1 by the conductive portion 11 or other heat conductive structure, and the circuit board 3 can be dissipated. However, even when there is a large amount of heat transferred over the housing assembly 1, the housing assembly 1 also does not dissipate heat quickly, so that a phenomenon in which some or all of the heat accumulates may occur. is there. Therefore, in order to dissipate heat from the housing assembly 1, the center board unit may further include a heat dissipation assembly 12 for transferring the heat on the housing assembly 1 to the outside. The heat dissipation assembly 12 accelerates the heat exchange between the housing assembly 1 and the outside by a method such as conduction or convection, rapidly releases the heat of the housing assembly 1 to maintain a low temperature, and with respect to the circuit board 3. This is convenient for guaranteeing the heat dissipation effect of the housing assembly 1.

Specifically, the heat dissipation assembly 12 can be divided into an active heat dissipation method and a passive heat dissipation method depending on the difference between the heat exchange mode and the operating method.

Here, as an embodiment of one heat dissipation assembly, the heat dissipation assembly 12 may include a fan 121 provided on the outside of the housing assembly 1, and at this time, the heat dissipation assembly 12 is an active heat dissipation system. The fan 121 accelerates the airflow exchange on the outside of the housing assembly 1 by driving the movement of the airflow, and carries away the heat accumulated on the housing assembly 1 by the fresh airflow outside by the convection method. It is possible to reduce the temperature and dissipate heat from the housing assembly 1. Due to the difference in the shape of the housing assembly 1, the fan 121 can be provided as a centrifugal fan or an axial fan.

Generally, the number of fans 121 may be one or a plurality depending on the structure of the center board unit and the operating environment, and the fans 121 may be provided at different positions outside the housing assembly 1.

The fan 121 is optionally provided on the outer wall of at least one housing member in order to form a strong convective heat exchange effect on the fan 121. In this way, the fan 121 expels hot air in the vicinity of the outer wall of the housing member so that fresh and cold air from the outside enters the region in the vicinity of the outer wall of the housing member, and is connected to the outer wall of the housing member. Heat exchange can be realized. Further, the fan 121 may be provided at another position such as a position where there is a certain distance from the housing member.

Further, when the heat dissipation assembly 12 includes the fan 121, a heat dissipation structure may be further provided on the outer wall of the housing member provided with the fan 121. The heat dissipation structure usually has a large heat dissipation area and can accelerate heat exchange between the outer wall of the housing member and the outside air.

Optionally, the heat dissipation structure may include heat dissipation fins 122. The heat dissipation fins 122, also referred to as heat sinks, are generally made of a metal or other material having good thermal conductivity such as copper or aluminum, and generally, the heat dissipation fins 122 are formed by a plurality of fins provided at intervals. When the external airflow flows through the gap between the heat radiation fins 122, heat exchange is performed at the same time as the surfaces of the plurality of fins to increase the surface area of the heat exchange surface, so that the heat radiation rate can be increased. In general, the shape and structure of the radiating fin 122 can all have a plurality of different types and are not described in detail here.

In order to give the heat dissipation fins 122 high heat dissipation efficiency, it is usually necessary to maintain good contact and heat conduction between the heat dissipation fins 122 and the outer wall of the housing member.

Further, as another embodiment of the heat dissipation assembly, the heat dissipation assembly 12 may include a heat pipe. A working medium is included in the heat pipe, and the working medium is generally variable in state between a liquid and a gas. When the heat pipe receives heat, the working medium located at one end inside the heat pipe evaporates to become a gas due to the temperature rise, and the gas working medium flows to the other end of the heat pipe to cool and dissipate heat. Completes the heat transfer. The working medium from which the heat is released returns to the liquid and returns to its original position. In this way, the state of the working medium in the heat pipe is constantly changing, the heat dissipation assembly 12 completes the heat transfer quickly, ensuring that the circuit board 3 operates at an appropriate temperature. The specific structure and installation method of the heat pipe can be any method well known to those skilled in the art, and will not be described in detail here.

As yet another embodiment of the heat dissipation assembly, the heat dissipation assembly 12 may include a semiconductor heat dissipation element. The semiconductor heat dissipation element operates by transferring the heat generated when an electric current passes through the semiconductor thermocouple, and transfers the heat from one end to the other end of the thermocouple. The specific operating principle, structure, and installation method of the semiconductor heat radiating element can be any method well known to those skilled in the art, and will not be described in detail here.

In order to increase the heat transfer rate between the housing assembly 1 and the circuit board 3 and between the housing assembly 1 and the outside, the housing member can generally be a metal member, which can be selected. Since metal has high structural strength and excellent thermal conductivity, the use of metal housing members can ensure that the housing assembly forms good protection against the circuit board 3. Effective heat dissipation can be obtained from the circuit board 3. Further, the metal housing member has advantages that it is easy to process and manufacture, and the formed housing assembly 1 is generally good. Specifically, the housing member can generally be made of a light metal material having high thermal conductivity, such as aluminum or an aluminum alloy.

Since all of the circuit boards 3 are housed in the housing assembly 1, they are further connected to the circuit board 3 by using the connector assembly 2 in order to realize information transmission between the circuit board 3 and the outside. Need to be realized. Each of the connector assemblies 2 is fixed on the housing assembly 1, and in this way, the distribution concentration of the connector assembly 2 is increased and the compactness is improved. The connector assembly 2 generally includes an electrical connector member 21 in order to satisfy the connection requirements between the circuit board 3 and other devices and members. In this way, the electric connector member 21 can be connected to other external members by a method of inserting and removing, thereby connecting the circuit board 3 and the external member, and realizing power supply and signal transmission. Can be done.

Specifically, the electrical connector member 21 may typically include two connecting portions that correspond to each other, for example, the electrical connector member 21 may include at least one of a plug or socket. In this way, by connecting the plug and the socket, an electrical connection between the circuit board 3 and the external member can be realized, and it is easy to insert and remove.

In order to connect the connector assembly 2 to a plurality of other devices or members at the same time, the connector assembly 2 may optionally include a plurality of electrical connector members 21 such as a pump, a battery, a radar, and the like. It is used to electrically connect to at least one component such as a visual sensor, infrared sensor, visual lamp, fan, breakout board, avionics system, 4G network interface card, gimbal, camera, etc. In this way, the plurality of electrical connector members 21 can be used to provide power and communication connections to a plurality of different devices or assemblies on an unmanned aerial vehicle to ensure normal flight and other operation of the unmanned aerial vehicle. ..

Here, optionally, the electrical connector member 21 can be used to transmit at least one of the power supply signal or the communication data signal, so that the centerboard unit is the other device and part by the connector assembly 2. Can provide power to, or provide communication connectivity and data transmission.

At this time, in order to connect other equipment and members located outside the center board unit to the circuit board 3 in the housing assembly 1 by the electric connector member 21, the electric connector member is selectively inserted into the hollow cavity. A plug hole 13 for this purpose is provided on the housing assembly 1. In this way, the electric connector member 21 can enter the inside of the housing assembly 1 through the plug hole 13 and realize an electrical connection with the circuit board 3 housed in the hollow cavity, and the housing assembly 1 can be formed. , Still exerts a protective action on the internal circuit board 3.

Here, in order to connect to the electric connector member, a corresponding electric connector, terminal, lead wire, or the like is generally provided on the circuit board, and it is used to fix and connect the electric connector member.

When the plug holes 13 are provided on the housing assembly 1, two different types of plug holes can be provided on the housing assembly depending on the position where the plug holes 13 are provided. For example, even if the housing assembly 1 includes at least one first plug hole 13a provided on one housing member, it is provided on the housing assembly 1 at a joint between two adjacent housing members. It may include at least one second plug hole 13b. The housing assembly 1 may include only the first plug hole 13a, only the second plug hole 13b, or the first plug hole 13a and the second plug hole 13b at the same time. The installation method can be provided according to the specific structure of the center board unit and the need for actual connection.

Here, since the first plug hole 13a is provided on one single housing member, the first plug hole 13a is a complete through hole provided on the housing member. The first plug hole 13a is generally provided at a position close to the center of the housing member in order to provide a sufficient internal space for the electric connector member 21 inserted into the first plug hole 13a.

Since the second plug hole 13b is provided at the seam between two adjacent housing members, neither of the two housing members can form a complete second plug hole 13b. At this time, the hole wall of the second plug hole 13b is formed by joining the edges of two adjacent housing members. Generally, at this time, a groove is provided on the edge of the housing member, and after abutting the two opposing grooves, one complete second plug hole 13b can be formed.

Since the second plug hole 13b is made of a different housing member, the electric connector member 21 inserted into the second plug hole 13b is one side of the second plug hole 13b while joining the housing members. After mounting on the hole wall of, the housing member can be completely joined and the electrical connector member 21 can be mounted in the complete second plug hole 13b.

In order to ensure that the housing assembly 1 provided with the plug hole 13 still maintains the sealing property, the electrical connector member 21 and the plug hole 13 are generally sealed with a sealing structure or a sealing member. Can be done. A second sealing member is optionally provided between the electrical connector member 21 penetrating the first plug hole 13a and the first plug hole 13a in order to seal the first plug hole 13a. be able to. In this way, the second sealing member seals the gap between the first plug hole 13a and the electric connector member 21, and external dust, moisture, or other foreign matter is introduced into the first plug hole. It is possible to prevent the housing assembly 1 from entering the inside of the housing assembly 1 through the gap between the 13a and the electric connector member 21.

Further, since a ring-shaped gap is generally formed between the first plug hole 13a and the electric connector member 21 inserted into the first plug hole 13a, the second sealing member is usually a seal ring. Can be. Since the shape of the seal ring is a closed ring, a closed shape without openings or breaks is formed in the ring gap, whereby the ring gap can be sealed.

The second sealing member may be a rubber seal ring or a silicone rubber seal ring so that the second sealing member can optionally form a good seal. In this way, the pressure between the electric connector member 21 and the hole wall of the first plug hole 13a causes the second sealing member to be deformed, so that the second sealing member is placed in the gap. It is filled and the hole walls of the electric connector member 21 and the first plug hole 13a are brought into close contact with each other so that the hollow cavity made of the housing member has a good sealing property.

Selectably, the electrical connector member mounted in the second plug hole 13b is generally connected to the second plug hole 13b by a method such as engagement, and therefore is sealed by an additional sealing member. It is inconvenient to realize. At this time, in order to seal the second plug hole 13b, the gap between the electric connector member 21 penetrating the second plug hole 13b and the second plug hole 13b is sealed with a sealing material. Can be done. When providing the sealing material, usually, the electric connector member 21 is first bonded to the inside of the second plug hole 13b, and then the gap between the electric connector member 21 and the second plug hole 13b is formed by a discharge method. It can be filled to seal the second plug hole 13b.

Here, the plurality of electrical connector members 21 in the connector assembly 2 can generally include at least one of ordinary external plugs 21a and SR plugs 21b. Here, the ordinary external plug 21a can be fixed and connected through an through hole by an electric connector such as a socket provided on the circuit board 3, and is generally used for the first plug hole 13a. Suitable for. Since the SR plug 21b is generally provided with a structure such as a flexible positioning button and can be engaged and fixed in the plug hole, the SR plug 21b is generally in the second plug hole 13b. Connected to. The number and arrangement method of the ordinary external plugs 21a and SR plugs 21b are both determined by the structure and installation method of the center board unit.

Since it has a plurality of electronic components and modules connected to the electrical connector member 21 inside the centerboard unit, one option is to maintain the normal operation of the centerboard unit when the unmanned aerial vehicle flies. In a possible embodiment, the housing assembly 1 can be connected to the body of the unmanned aerial vehicle via a flexible structure. Such a flexible structure can use its own deformation to absorb and filter the vibrations that occur when the unmanned aerial vehicle flies, ensuring that the centerboard unit operates normally.

Optionally, the flexible structure may include a flexible connecting member 14 having one end connected to the housing assembly 1 and the other end connected to the body of the unmanned aerial vehicle. Since the flexible connecting member 14 itself has elasticity, it is possible to absorb the vibration of the main body by the elastic deformation generated by itself and attenuate the vibration to an appropriate degree when transmitting it to the housing assembly 1.

In order to support the housing assembly 1 in a balanced manner, there are a plurality of flexible connecting members 14, and the plurality of flexible connecting members 14 are provided symmetrically with respect to the housing assembly 1. In this way, the flexible connecting member 14 symmetrically supports the housing assembly 1 and filters vibrations from each direction to provide stable support to the housing assembly 1.

Specifically, the flexible connecting member 14 may be a silicone rubber column or another structural member capable of simultaneously providing vibration absorption and support.

A plurality of electronic components are provided, and the connector assembly is electrically connected to the electronic components. In this way, by performing electrical connection and signal transmission using the circuit board and the external member, functions such as power distribution and communication transmission to other members are performed, and a sealed structure is formed on the outside of the circuit board. However, external dust, water droplets and other foreign matter do not affect the normal operation of the circuit board, and the normal operation of the center board unit is guaranteed.
