[0002] The detection equipment is a key piece of equipment used to monitor the flight of drones. The radio frequency chip inside it generates a lot of heat when it is running. Traditional heat dissipation uses a fan to blow directly on the radio frequency chip, which is inefficient and the radio frequency chip is prone to overheating, causing the device to freeze, restart or degrade in performance, thus affecting the detection capability.

[0003] Therefore, how to provide a solution to overcome or alleviate the above-mentioned defects remains a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0027] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] In the description of the embodiments of this application, it should be noted that the orientation or positional relationship indicated by "up", "down", "left", "right", "front", "back", etc. is based on the accompanying drawings and is only for the convenience of description, and is not intended to indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0029] like Figure 1 , Figure 2 As shown, Figure 1 for Figure 1 This is a schematic diagram of the structure of a detection device 1 in an embodiment of this application; Figure 2 for Figure 1 An exploded view of the detection device 1 shown in the image.

[0030] This application provides a detection device 1, including a housing 11, a heat dissipation assembly 12, and a control module 13. The housing 11 includes an inner chamber, and the heat dissipation assembly 12 and the control module 13 are located in the inner chamber. The heat dissipation assembly 12 includes a heat dissipation plate 121 and a blower 122. The heat dissipation plate 121 includes a heat dissipation duct, and the blower 122 includes an air outlet facing the heat dissipation duct. The control module 13 includes a heating element, and the heating element is heat-transferringly connected to the heat dissipation plate 121.

[0031] This embodiment does not limit the shape of the outer shell 11. For example, in this embodiment, the outer shell 11 is a cuboid structure, which is convenient for processing and easy for people to handle.

[0032] In some embodiments, the outer casing 11 includes a base 112 and an outer cover 111, wherein the base 112 is a rectangular plate and the outer cover 111 is a rectangular frame, as can be referred to. Figure 1 As shown, the base 112 is located on the left side and the outer cover 111 is located on the right side. The outer cover 111 surrounds the outer edge of the base 112, and the outer cover 111 and the base 112 form a box-shaped structure with an inner compartment, in which the heat dissipation component 12 and the control module 13 are installed.

[0033] In some implementations, the outer cover 111 and the base 112 can be separate structures, as shown in the diagram; the outer cover 111 and the base 112 can be manufactured separately and then connected together. This facilitates the manufacturing of the outer cover 111 and the base 112, and also facilitates the inspection and maintenance of related structures inside the cabin. For example, when it is necessary to inspect the heat dissipation component 12 or the control module 13, the base 112 can be disassembled for inspection. The connection between the outer cover 111 and the base 112 can be achieved using fasteners such as screws, or by snap-fitting, bonding, or riveting.

[0034] In other implementations, the outer cover 111 and the base 112 can be a single molded structure. This simplifies the assembly of the detection device 1.

[0035] Similarly, this embodiment does not limit the shape of the heat sink 121. For example, in this embodiment, the heat sink 121 is a rectangular plate structure, which is convenient for processing. The heat sink 121 is provided with a plurality of heat sinks 121a. The plurality of heat sinks 121a are distributed along the same direction to form a plurality of heat dissipation channels. It can be understood that a heat dissipation channel is formed between two adjacent heat sinks 121a. The air outlet of the blower 122 is directed toward the heat dissipation channel, and the blower 122 is fixed to one side of the heat dissipation channel. (Refer to...) Figure 2 As shown, the left side of the heat sink 121 consists of multiple heat sinks 121a and a heat dissipation duct, while the right side of the heat sink 121 is a blower 122. The blower connects the heating element of the control module 13 to the heat sink 121 for heat transfer, allowing the heat from the heating element to be transferred to the heat sink. Exemplarily, in this embodiment, the heat transfer connection involves the heating element and the heat sink 121 being in close contact, with the heat generated by the heating element being transferred to the heat sink 121. Alternatively, a thermally conductive layer can be added between the heating element and the heat sink 121, allowing the heat from the heating element to be transferred to the heat sink through the thermally conductive layer. The choice depends on the actual heat dissipation requirements. During operation, the blower 122 generates a high-pressure airflow. This high-pressure airflow rushes out along the heat dissipation duct, carrying away the transferred heat quickly, thus continuously carrying away the heat generated by the heating element, providing good heat exchange efficiency and excellent heat dissipation capabilities.

[0036] In practice, multiple heat sinks 121a can be evenly distributed along the same direction to make the multiple heat dissipation channels evenly distributed. The high-pressure airflow generated by the blower 122 can be evenly distributed to the multiple heat dissipation channels to achieve a uniform heat dissipation effect on the heat-generating components of the control module 13.

[0037] In other examples, the distribution of multiple heat sinks 121a may also be non-uniform, depending on the number and distribution of heat-generating elements and their heat dissipation requirements. In applications, the structural form and distribution of heat sinks 121a can be determined through simulation or experimentation.

[0038] In some embodiments, the housing 11 includes a base 112 and a main air vent 1121, with the heat dissipation assembly 12 located between the base 112 and the control module 13; the blower 122 includes an air inlet, and the main air vent 1121 corresponds to the air inlet, located on the base 112. To facilitate the operation of the blower 122, the main air vent 1121 is provided on the side of the base 112 near the blower 122, i.e., above the base 112, so that the main air vent 1121 corresponds to the air inlet of the blower 122. The main air vent 1121 provides airflow to the blower 122, ensuring the operation of the blower 122. At the same time, the main air vent 1121 is designed as a grille structure to prevent impurities in the air from entering the heat dissipation assembly.

[0039] In some embodiments, the outer casing 11 further includes an outer cover 111, a first air vent 1111, and a second air vent 1112. The first air vent 1111 and the second air vent 1112 are respectively located on both sides of the outer cover 11 along a first direction; the first direction is the distribution direction of the blower 122 and the heat dissipation duct. The first air vent 1111 and the second air vent 1112 are respectively provided on the left and right sides of the outer cover 111 along the first direction, facilitating airflow. In this embodiment, both the first air vent 1111 and the second air vent 1112 are rectangular openings for ease of processing. (Reference) Figure 2 As shown, the second air vent 1112 is located near the air outlet of the blower 122, while the first air vent 1111 is located away from the air outlet. When the blower 122 is running, the air inlet primarily draws in air through the main air vent 1121, with the first air vent 1111 serving as a secondary intake. After the airflow is blown out from the air outlet, the air outlet pushes the airflow along the first direction and out through the second air vent 1112, creating a linear flow field along the first direction. This allows the cold air to pass through the entire device without interference along the first direction, which is beneficial for improving heat exchange efficiency. In practical applications, if the main air vent 1121 is blocked, the blower 122 will primarily draw in air through the first air vent 1111, with the main air vent 1121 serving as a secondary intake. By utilizing the first air vent 1111 and the second air vent 1112 to create a linear flow field along the first direction, the heat dissipation function is still achieved. It is worth noting that when the blower 122 is not working, the main air outlet 1121, the first air outlet 1111, and the second air outlet 1112 can still serve as channels for heat exchange with the outside air, providing heat dissipation conditions for the detection device 1 in this embodiment.

[0040] In some embodiments, the heat dissipation assembly 12 further includes at least two dustproof parts 123, which are respectively fixed to the side of the first air vent 1111 and the second air vent 1112 near the inner chamber. The dustproof parts 123 are positioned to the left of the first air vent 1111 along the first direction and to the right of the second air vent 1112 along the first direction to block solid particles such as dust, lint, and hair from entering the equipment. This embodiment does not limit the dustproof part 123; for example, in this embodiment, the dustproof part 123 is a dustproof net. When it is necessary to clean the solid particles blocked by the dustproof part, the dustproof net can be directly disassembled, cleaned, and then fixed back in its original position, which helps to provide a clean working environment for the heat dissipation assembly 12.

[0041] In some embodiments, the flow direction of the heat dissipation duct is the same as the air outlet direction of the blower 122. In this embodiment, the flow direction of the heat dissipation duct is parallel to the first direction, and the air outlet direction of the blower 122 is also the first direction. When the airflow is blown out from the air outlet by the blower 122 and out from the parallel heat dissipation duct, it helps to reduce airflow turbulence and friction, and reduce energy loss.

[0042] In the case where the outer casing 11 is a cuboid, the distribution direction of the heat dissipation duct and the blower 122 can be along the width direction of the outer casing 11, and the flow direction of the heat dissipation duct is also along the width direction of the outer casing 11. The aforementioned first air vent 1111 and second air vent 1112 are positioned correspondingly in the width direction of the outer casing 11.

[0043] In some embodiments, the control module 13 includes a control unit 132 and an RF detection unit 134. The RF detection unit 134 includes a temperature sensor 133, which is electrically connected to the control unit 132 along with the blower 122. The heating element includes the RF detection unit 134. The control module 13 also includes a motherboard 131, on which the control unit 132 is integrated. The control unit 132 is electrically connected to the RF detection unit 134 and the blower 122. The heating element includes, but is not limited to, the RF detection unit 134. An RF chip is provided on the RF detection unit 134. The temperature sensor 133 can detect the temperature of the RF chip. The heat dissipation assembly 12 dissipates heat from the RF chip. Specifically, the temperature sensor 133 detects the temperature value, and the control unit 132 controls the heat dissipation rate of the heat dissipation assembly 12 based on the detected temperature value. This includes, but is not limited to, starting, stopping, and adjusting the speed of the blower 122. Figure 3 As shown, Figure 3 This is a diagram showing the relationship between the control module and the heat dissipation components.

[0044] refer to Figure 2As shown, the heat sink 121 is fixed to the side of the RF detection unit 134 facing the base 112, bringing the RF detection unit 134 into contact with the heat sink 121. The heat generated by the RF chip is transferred to the heat sink 121 and then carried away by the airflow generated by the blower 122. The specific heat dissipation adjustment process is as follows: when the temperature sensor 133 detects that the temperature is lower than the set low-temperature threshold, the control unit 132 controls the blower 122 to remain stopped; when the temperature reaches or exceeds the low-temperature threshold but is lower than the high-temperature threshold, the control unit 132 automatically starts the blower 122 and operates it at low speed; when the temperature further rises to the high-temperature threshold, the control unit 132 controls the blower 122 to enter a high-speed operation mode. For example, the low-temperature threshold can be 50°C, and the high-temperature threshold can be 65°C. The low-temperature threshold and the high-temperature threshold can be set according to the actual operating temperature required by the control unit 132 and the RF detection unit 134; this embodiment does not impose any limitations.

[0045] In this embodiment, the heat sink 121 is made of aluminum. Aluminum has good thermal conductivity, which can quickly conduct and disperse the heat generated by the heating element from the heating element to the entire heat sink 121, avoiding localized overheating of the heat sink 121. Furthermore, aluminum is easy to process, and multiple heat sinks 121a can be directly processed on the heat sink 121 to obtain a heat sink 121 with heat dissipation channels.

[0046] In this embodiment, the detection device 1 further includes an antenna assembly 18. The antenna assembly 18 includes, but is not limited to, a GPS (Global Positioning System) antenna 181 and an antenna section 182. The antenna section 182 includes, but is not limited to, an omnidirectional antenna and a linear antenna, used to detect the direction and distance of the drone. Correspondingly, a GPS mounting section and an antenna hole are provided on the outer casing 111, as shown in the reference... Figure 2 As shown, the GPS mounting part is located on the upper left side of the inner wall of the outer casing 111, the antenna hole is located on the top of the outer casing 111, and the antenna assembly 18 at least partially protrudes through the antenna hole. The radio frequency detection unit 134 is connected to the antenna assembly 18 and the GPS antenna 181 and is used to process the antenna signal.

[0047] In some embodiments, the blower 122 is embedded in the heat sink 121. This integrated design, where the blower 122 is directly embedded in the heat sink 121, reduces the size of the equipment and makes it easier to use.

[0048] In some embodiments, the heat dissipation assembly 12 further includes a sealing gasket 124, which is fixed between the base 112 and the heat dissipation plate 121. The heat dissipation plate 121 is fixed between the base 112 and the control module 13. A sealing gasket 124 is provided between the heat dissipation plate 121 and the base 112. The sealing gasket 124 can be a ring or annular structure adapted to the shape of the heat dissipation plate 121. For example, if the heat dissipation plate 121 is rectangular, the sealing gasket 124 can be a rectangular sealing ring or sealing ring. The sealing gasket 124 is fixed around the blower 122 and the heat dissipation duct to prevent water ingress and ensure the safety of the equipment.

[0049] In this embodiment, the detection device also includes a mounting bracket 14. The shape of the mounting bracket is not limited in this embodiment; for example, the mounting bracket 14 is rectangular. The mounting bracket 14 is fixed to the inner cabin. The mounting bracket 14 includes a first accommodating compartment and a second accommodating compartment, both with their hatches facing the base. Figure 2 As shown, the first receiving compartment is located above the fixing frame 14, and the second receiving compartment is located below the fixing frame 14. The control module 13 is fixed to the first receiving compartment.

[0050] The detection device 1 also includes a transmission component 16 and a battery 17. The transmission component 16 is fixed to the bottom of the second housing compartment, and the battery 17 is fixed above the transmission component 16. Furthermore, the mounting bracket 14 has multiple support pillars on the side facing the base. These pillars are connected to the base 112, thus securing the mounting bracket 14 and the base 112. The mounting bracket supports the control module 13, the transmission component 16, and the battery 17, preventing deformation from external impacts.

[0051] The bottom of the outer casing 111 has a through hole through which the transmission component 16 at least partially extends. A data interface and a headphone jack are located on the side of the transmission component 16 near the through hole, allowing data or headphone cables to pass through and connect to the transmission component 16. Connecting the transmission component 16 to the control module 13 allows it to transmit data and audio to the control module 13. Corresponding to the through hole, the outer casing 111 has a first hole cover, which is placed over the through hole when not in use for dust prevention. The battery 17 is connected to the blower 122, the control module 13, and the transmission component 16 to supply power and ensure the operation of the equipment.

[0052] In some embodiments, the control module 13 further includes multiple buttons 135, which are fixed to the same side of the housing 11 near the control module 13. A button signal section is also provided on the main board 131, with openings at corresponding positions on the outer cover 111. The buttons 135 are fixed to one side of the button signal section, with at least a portion of each button 135 protruding through the openings, facilitating direct pressing of the buttons 135 to trigger the button signal section and cause the control module 13 to execute commands corresponding to the button 135's function. The multiple buttons 135 may include volume up, volume down, or power on / off buttons, and may also include other function buttons. Positioning the multiple buttons 135 on the same side of the housing 11 allows for one-handed operation when the user holds the detection device 1 with one hand.

[0053] In some embodiments, the outer wall surface of the housing 11 is provided with an anti-slip part 4, which is located at the gripping part of the housing 11.

[0054] refer to Figure 2 As shown, the anti-slip part 4 includes a first anti-slip part and a second anti-slip part. The first anti-slip part is fixed to the base 112, and the second anti-slip part is fixed to the outer cover 111. Specifically, the first anti-slip part is located on one side of the main air vent 1121, and the second anti-slip part is located on one side of the first anti-slip air vent 1111 and the second anti-slip air vent 1112. When a person holds the detection device 1 of this embodiment, their hand can directly hold the first and second anti-slip parts to prevent the detection device 1 from slipping. This embodiment does not limit the first and second anti-slip parts; they can be set according to actual usage conditions, as long as they can ensure that the detection device 1 will not slip when held. For example, in this embodiment, the second anti-slip part is an anti-slip soft rubber with a concave-convex structure, allowing the hand to directly hold the concave-convex part, increasing the friction with the detection device 1 and preventing slipping.

[0055] The base 112 is also provided with a first buckle 1122 and a second buckle 1123, see reference. Figure 2 As shown, a first buckle 1122 is provided above the outer surface of the base 112, and a second buckle 1123 is provided below the base 112. The wrist strap can be inserted into the first buckle 1122 and the second buckle 1123. When in use, the user can pass between the wrist strap and the base 112 to hold the device, which is convenient for use.

[0057] The detection device 1 also includes a screen assembly 15, which includes, but is not limited to, a screen 151, a bottom frame 152, and a screen frame 153. (See reference...) Figure 2As shown, the bottom frame 152 is fixed to the side of the mounting bracket 14 away from the base 112, i.e., the right side of the mounting bracket 14. The screen 151 is fixed to the right side of the bottom frame 152, and the screen frame 153 is fixed to the side of the screen 151 away from the bottom frame 152. The bottom frame 152 supports the screen 151 to prevent electromagnetic interference to the screen 151, and the screen frame 153 fixes the screen 151 to prevent it from loosening or shifting. The screen 151 is connected to the control module 13 and can display detection data such as drone signals, spectrum, and distance.

[0058] To facilitate switching between different networks, this embodiment includes a SIM card slot on the motherboard 131 and a corresponding SIM card insertion hole and a second cover on the outer casing 111. The second cover is placed over the SIM card insertion hole. After inserting the SIM card 2 into the SIM card slot on the motherboard 131, the second cover is closed to prevent dust. A waterproof plug 19 is provided between the SIM card insertion hole and the SIM card slot to prevent water from entering the inner compartment through the SIM card insertion hole.
