Description

Technical Field

[0001] This disclosure relates to the field of positioning devices, and specifically to a positioning device. Background Technology

[0002] In the prior art, positioning devices typically include a housing and a circuit board and signal processing module housed within the housing. During operation, the circuit board and signal processing module usually generate heat. To ensure heat dissipation performance, heat dissipation fins are usually installed. At the same time, the distance between the circuit board and the signal processing module is maximized to ensure sufficient space for heat dissipation. This results in a large size for the positioning device, making it difficult to carry and install.

[0003] Chinese patent CN210666029U, published on June 2, 2020, discloses a multi-functional positioning device, including a housing, a plurality of indicator lights, an integrated circuit board, at least one GPS antenna, and at least one GSM antenna. This device is small in size and easy to install. While ensuring basic positioning functions, it also has the ability to collect switch and analog signals. Utilizing 4G communication, it offers faster speeds and more flexible communication, enabling it to transmit location, operating status, and other data back to the user's service management platform or mobile app. This allows users to monitor vehicle equipment equipped with the positioning device in real time and perform simple statistical analysis on the transmitted data. While this device is small and easy to install, solving the problems of large size and difficulty in carrying and installing, it still has the following drawbacks:

[0004] Because the overall volume of the positioning device is reduced, heat dissipation fins (heat dissipation plates) are only set on the outer periphery. During operation, the heat generated inside the positioning device cannot be quickly dissipated to the outside, resulting in poor heat dissipation efficiency. In other words, the above-mentioned patent cannot balance volume and heat dissipation efficiency. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the purpose of this disclosure is to provide a positioning device that balances size and heat dissipation efficiency.

[0006] The positioning device disclosed herein includes a housing and a circuit board, a partition, an antenna assembly, and a heat dissipation assembly disposed within the housing.

[0007] The housing includes a base, a body, and a top cover. The base is connected to the bottom of the body, and the top cover is connected to the top of the body. The interior of the housing is divided into upper and lower cavities by a partition. The lower cavity is the first cavity, and the upper cavity is the second cavity. The partition has wire holes, and the circuit board is disposed in the first cavity. The circuit board has a heating area for housing the main heating element.

[0008] The antenna assembly is disposed within the second cavity and includes a mobile network antenna module and a positioning antenna module; the mobile network antenna module is connected to the partition and electrically connected to the circuit board;

[0009] The heat dissipation component is provided corresponding to the heat-generating area. The heat dissipation component includes a plurality of heat dissipation fins. The heat dissipation fins extend along a first direction of the heat-generating area, and the plurality of heat dissipation fins are arranged along a second direction of the heat-generating area. A gap is left between every two adjacent heat dissipation fins to form an airflow channel extending from one end of the heat-generating area to the other end.

[0010] The mobile network antenna module has a first through hole corresponding to the heat dissipation toothed plate for the heat dissipation toothed plate to pass through, and the heat dissipation toothed plate is connected to the partition plate; the positioning antenna module is disposed on the heat dissipation toothed plate and connected to the heat dissipation toothed plate;

[0011] The housing has heat dissipation windows formed at locations corresponding to the heat dissipation fins.

[0012] Preferably, the heat dissipation fins have stepped notches at the locations corresponding to the positioning antenna module, and the height of the stepped notches is adapted to the thickness of the positioning antenna module.

[0013] The mobile network antenna module includes a base plate and a plurality of communication antennas. The first through hole is formed on the base plate, and the plurality of communication antennas are disposed on both sides of the first through hole and electrically connected to the base plate.

[0014] Preferably, the heat dissipation assembly further includes a cooling fan, which is provided at at least one end of the airflow channel; the cooling fan is connected to the partition via a fan bracket.

[0015] Preferably, the heat dissipation fins located on the outer side extend outward from the end near the cooling fan to form an open structure facing the cooling fan.

[0016] Preferably, the antenna assembly further includes a wireless network antenna module, which is disposed in the second cavity and connected to the inner wall of the housing. The outer wall of the housing has a second through hole at the corresponding location of the wireless network antenna module and is provided with a first baffle that is detachably connected to the housing. The first baffle is adapted to the second through hole.

[0017] Inside the second cavity, a second baffle is provided at a position corresponding to the wireless network antenna module, and the second baffle is connected to the inner side wall of the housing.

[0018] Preferably, the positioning device further includes a power interface, which is disposed on the outer peripheral surface of the housing, with one end extending into the housing for electrical connection with the circuit board, and the other end protruding from the outer peripheral surface of the housing for electrical connection with an external power source.

[0019] Preferably, the positioning device further includes a local area network (LAN) interface, which is located on the same side as the power interface. One end of the LAN interface extends into the housing for electrical connection with the circuit board, and the other end protrudes from the outer periphery of the housing for electrical connection with a network cable.

[0020] Preferably, the positioning device further includes a wireless communication interface, which is located on the same side as the power interface. One end of the wireless communication interface extends into the housing for electrical connection with the circuit board, and the other end protrudes from the outer periphery of the housing for electrical connection with a network cable.

[0021] Preferably, the positioning device further includes a switch, which is disposed on the outer peripheral surface of the housing, with one end extending into the housing for electrical connection with the circuit board, and the other end protruding from the outer peripheral surface of the housing.

[0022] Preferably, the shell and the partition are integrally formed.

[0023] The positioning device described in this disclosure has the following advantages:

[0024] By setting up a partition, the interior of the housing is divided into upper and lower cavities, separating the antenna assembly and the circuit board. This ensures that there is a gap between the antenna assembly and the circuit board, and the partition separates them. This prevents the heat generation from increasing if the gap between the antenna assembly and the circuit board is too small while maintaining a suitable volume.

[0025] A dedicated heat-generating area is set up on the circuit board, and the main heat-generating components are placed in the heat-generating area, so that the heat generation of the circuit board is more concentrated, which facilitates the subsequent setting of heat dissipation components. At the same time, since the heat generation of the circuit board is more concentrated, the heat dissipation components can be set up in a targeted manner, so as not to make the heat dissipation components redundant, thereby enabling the overall volume of the positioning device described in this disclosure to be controlled within a small range.

[0026] The main heat-generating components are placed in the heat-generating area of ​​the circuit board. At the same time, the mobile network antenna module has a first through hole corresponding to the heat-generating area for the heat-dissipating fins to pass through. The heat-dissipating fins pass through the first through hole and are connected to the partition. The GPS antenna module is placed on the heat-dissipating fins. This allows the heat-generating components such as the heat-generating area of ​​the circuit board, the mobile network antenna module, and the GPS antenna module to be arranged around the heat-dissipating fins, which makes full use of the heat dissipation performance of the heat-dissipating fins. Thus, the positioning device described in this disclosure takes into account both size and heat dissipation efficiency. Attached Figure Description

Detailed Implementation

[0033] like Figures 1-3 As shown, a positioning device disclosed herein includes a housing 1 and a circuit board 2, a partition 3, an antenna assembly 4, and a heat dissipation assembly 5 disposed within the housing 1;

[0034] The housing 1 includes a base 103, a body 102, and a top cover 101. The base 103 is connected to the bottom of the body 102, and the top cover 101 is connected to the top of the body 102. The interior of the housing 1 is divided into upper and lower cavities by the partition 3. The lower cavity is the first cavity, and the upper cavity is the second cavity. The partition 3 has wiring holes, and the circuit board 2 is disposed in the first cavity. The partition 3 divides the interior of the housing 1 into the first cavity and the second cavity, and the circuit board 2 and the antenna assembly 4 are disposed in the second cavity. The antenna assembly 4 and the circuit board 2 assembly are separated, which can make better use of the internal space of the housing 1; the circuit board 2 has a heat-generating area, which is used to set the main heat-generating element; the heat-generating area is specially set on the circuit board 2, and the main heat-generating element is set in the heat-generating area, so that the heat generation of the circuit board is more concentrated, which facilitates the setting of the heat dissipation component; at the same time, since the heat generation of the circuit board is more concentrated, the heat dissipation component can be set in a targeted manner, so as not to make the heat dissipation component redundant, thereby controlling the overall volume of the positioning device described in this disclosure within a small range.

[0035] Specifically, the main heat-generating components include radio frequency PAs (power amplifier tubes) in various frequency bands. For example, the main N3 band PA is model GDM1828, the N1 band PA is model GCM2128, the N41 band PA is model GCM2627, and the N78 band PA is model GDM3528.

[0036] The shape of the shell 102 can be a hollow cylinder, a hollow elliptical cylinder, a hollow prism, etc. The base 103 and the top cover 101 are both adapted to the shell 102. The base 103, the shell 102 and the top cover 101 can be connected by conventional screws, or they can be connected by gluing, welding or other methods after the components of the circuit board 2 are installed into the shell 1. The implementation method is not limited.

[0037] Antenna assembly 4 is disposed in the second cavity and includes mobile network antenna module 401 and positioning antenna module 402; mobile network antenna module 401 is connected to partition 3 and electrically connected to circuit board 2;

[0038] Specifically, the mobile network antenna module 401 includes a base plate and several communication antennas, which can be 4G antennas and / or 5G antennas. A first through hole 4011 is formed on the base plate. The several communication antennas are electrically connected to the base plate. The base plate and the circuit board are connected at two points. The positioning is achieved by receiving signals from nearby 4G and / or 5G base stations.

[0039] The positioning antenna module 402 can be either GPS satellite positioning or BeiDou satellite positioning, and the choice can be made according to the region where the application scenario is located.

[0040] The heat dissipation component 5 is provided corresponding to the heat-generating area and includes a plurality of heat dissipation fins 501. The heat dissipation fins 501 extend along a first direction of the heat-generating area, and the plurality of heat dissipation fins 501 are arranged along a second direction of the heat-generating area. A gap is left between every two adjacent heat dissipation fins 501 to form an airflow channel extending from one end of the heat-generating area to the other end.

[0041] Specifically, such as Figure 4 As shown, the first direction of the aforementioned heat-generating area can refer to the length direction of the housing 102, and the second direction of the heat-generating area can refer to the width direction of the housing 102. That is, the heat dissipation fins 501 extend along the length direction of the housing, and several heat dissipation fins 501 are arranged along the width direction of the housing. There is a gap between adjacent heat dissipation fins 501 to form an airflow channel. The extension direction of the airflow channel is the length direction of the housing 102, that is, it extends from one end of the heat-generating area to the other end of the heat-generating area. The heat generated by the circuit board 2, the mobile network antenna module 401, and the positioning antenna module 402 is guided through the airflow channel.

[0042] The mobile network antenna module 401 has a first through hole 4011 through which the heat dissipation tooth 501 passes. The heat dissipation tooth 501 is connected to the partition plate 3. The connection between the heat dissipation tooth 501 and the partition plate 3 can be fixed by conventional fasteners such as screws, or by adhesive. The implementation method is not limited.

[0043] The positioning antenna module 402 is mounted on the heat dissipation fin 501 and connected to the heat dissipation fin 501. Since the positioning antenna module 402 is small in size, if it is mounted in other locations, the heat generated by it may not be effectively or efficiently carried away by the heat dissipation components. Therefore, the positioning antenna module 402 is mounted on the heat dissipation fin 501.

[0044] Specifically, the positioning antenna module 402 is positioned above the heat dissipation fin 501, and from a top-down view, the positioning antenna module 402 just covers part of multiple airflow channels. When the positioning antenna module 402 generates heat, the airflow in the airflow channels carries away the heat generated by the positioning antenna module 402 in a timely manner, thereby ensuring the operating environment of the positioning antenna module 402.

[0045] The housing 102 has a through heat dissipation window 104 at the location corresponding to the heat dissipation fins 501.

[0046] Specifically, such as Figure 1 and Figure 2 The diagram shows one embodiment of the heat dissipation window 104 in this solution. A heat dissipation window 104 is formed on the outer periphery of the shell 102, extending through its wall thickness. The shell 102 is a hollow quadrangular prism. The heat dissipation window 104 is formed at a position corresponding to the heat dissipation fins 501. The number of heat dissipation windows 104 is not limited. It can be formed on only one side wall of the shell 102, or on each of the two opposite side walls of the shell 102, or on each of the four side walls of the shell 102.

[0047] The heat dissipation window 104 is correspondingly set with the heat dissipation fin 501. Due to the setting of the first through hole 4011, the heat dissipation fin 501 passes through the first through hole 4011 and is set on the partition plate 3, so that the heat dissipation fin 501 is very close to the mobile network antenna module 401. The heat generated by the mobile network antenna module 401 during operation can be quickly guided by the heat dissipation fin 501 and dissipated from the heat dissipation window 104 to the outside of the housing 1. While making good use of the internal space of the housing 1, the heat dissipation effect of the mobile network antenna module 401 can also be kept at a good level.

[0048] Meanwhile, since the circuit board 2 is located in the first cavity, some of the heat generated by the circuit board 2 is transferred through the partition 3. The heat dissipation fins 501 are connected to the partition 3, which can also quickly guide and dissipate the heat generated by the circuit board 2 and transferred to the partition 3. This allows the positioning device described in this disclosure to balance size and heat dissipation efficiency.

[0049] Furthermore, the positioning antenna module 402 is used to receive satellite signals for positioning. Its volume is smaller than that of the mobile network antenna module 401. Placing it inside the housing 1 does not affect the overall volume of the housing 1. However, in order to make the volume of the positioning device described in this disclosure as small as possible, the heat dissipation fin 501 has a stepped notch formed at the position corresponding to the positioning antenna module 402, which can avoid increasing the overall thickness of the positioning device. Since the positioning antenna module 402 is placed on the heat dissipation fin 501, the heat dissipation fin 501 can guide the heat generated by the positioning antenna module 402 in a timely manner and disperse it to the outside of the housing 1 through the heat dissipation window 104, ensuring heat dissipation efficiency.

[0050] Due to the arrangement of the heat dissipation fins 501, there is a certain space inside the housing 1 and on both sides of the heat dissipation fins 501. Therefore, several communication antennas in the mobile network antenna module 401, namely the 4G antenna and 5G antenna mentioned above, are arranged on both sides of the heat dissipation fins 501, that is, several communication antennas are arranged on both sides of the first through hole 4011.

[0051] Several communication antennas are arranged on both sides of the first through hole, which effectively utilizes the space left by the heat dissipation fins inside the housing. The several communication antennas are arranged on both sides of the heat dissipation fins, which not only improves the space utilization rate, but also ensures that the heat generated by the communication antennas during operation can be carried away by the heat dissipation fins in time, thus ensuring heat dissipation efficiency; it takes into account both size and heat dissipation efficiency.

[0052] Furthermore, to ensure heat dissipation efficiency, such as Figure 2 and Figure 4 As shown, a cooling fan 502 is provided at at least one end of the airflow channel; the cooling fan 502 is connected to the partition 3 via a fan bracket 503.

[0053] Specifically, a cooling fan 502 can be installed at the outlet end of the airflow channel, or at the inlet end of the airflow channel, or one cooling fan 502 can be installed at both the inlet and outlet ends of the airflow channel; the specific setting can be selected according to the actual situation; it should be noted that if one cooling fan 502 is installed at both the inlet and outlet ends of the airflow channel, the airflow direction of the cooling fan 502 installed at the inlet end should be set to guide the airflow into the airflow channel in order to ensure the heat dissipation efficiency of the overall heat dissipation component 5.

[0054] The cooling fan 502 is electrically connected to the circuit board 2. When the circuit board 2 is powered on, the cooling fan 502 starts to work, ensuring that the time required for the inside of the housing 1 to rise to a higher temperature is longer, thus providing a better operating environment for the circuit board 2 and the antenna assembly 4.

[0055] Furthermore, in order to cooperate with the cooling fan 502, the heat dissipation fins 501 located on the outer side extend outward from the end near the cooling fan 502 to form an open structure facing the cooling fan 502.

[0056] Specifically, such as Figure 4 As shown, the cooling fan 502 is installed at the outlet end of the airflow channel, thus forming an open structure at the outlet of the airflow channel. That is, the ends of the two heat dissipation fins 501 located on the outside extend outward, making the outlet of the airflow channel open. The opening at the outlet of the airflow channel creates a pressure difference between the middle and the outlet of the airflow channel, which accelerates the airflow speed, thereby accelerating the heat dissipation speed and improving the heat dissipation efficiency.

[0057] Meanwhile, if the cooling fan 502 is located at the inlet end of the airflow channel, an open structure can also be formed at the inlet of the airflow channel. That is, the end of the heat dissipation fin 501 located on the outside extends outward, so that an open structure is formed at the outlet of the airflow channel, thereby increasing the gas flow rate into the airflow channel, ensuring sufficient heat exchange of the gas, and improving the heat dissipation efficiency.

[0058] The open structure can be formed at both the inlet and outlet of the airflow channel, or one of them can be selected. The specific setting can be selected according to the configuration of the cooling fan 502.

[0059] Meanwhile, to facilitate the processing of open structures, stepped notches, and other structures, the heat dissipation fins 501 can be divided into multiple groups, with each group processed according to requirements, such as... Figure 4 As shown, the heat dissipation fins 501 are divided into three groups. One group is made with an open structure, another group uses ordinary heat dissipation fins 501, and the third group is processed with a stepped notch structure.

[0060] The configuration of the aforementioned heat dissipation fins 501 can be selected according to the actual situation.

[0061] Furthermore, in order to ensure positioning accuracy, the antenna assembly 4 also includes a wireless network antenna module 403. The wireless network antenna module 403 is disposed in the second cavity and connected to the inner side wall of the housing 102. The outer side wall of the housing 102 has a second through hole 1021 corresponding to the wireless network antenna module 403, and is provided with a first baffle 6 that is detachably connected to the housing 102. The first baffle 6 is adapted to the second through hole 1021.

[0062] Inside the second cavity, a second baffle 7 is provided at a position corresponding to the wireless network antenna module 403, and the second baffle 7 is connected to the inner wall of the housing 102.

[0063] Because the wireless network antenna module 403 is small in size and generates less heat compared to the mobile network antenna module 401 and the positioning antenna module 402, it is directly connected to the inner wall of the housing 102. To facilitate maintenance or replacement of the wireless network antenna module 403, a second through hole 1021 is provided on the outer wall of the housing 102 at a location corresponding to the wireless network antenna module 403, extending along the thickness of the housing 102 sidewall. A first baffle 6 is also provided, which is adapted to the second through hole 1021. The first baffle 6 is connected to the housing 102. The side wall of 02 is detachably connected and just covers the second through hole 1021; at the same time, in order to prevent the positioning antenna module 402 and the mobile network antenna module 401 from causing too much interference to the signal of the wireless network antenna module 403, a second baffle 7 is set on the inner side wall of the inner shell 102 of the second cavity, corresponding to the wireless network antenna module 403. The second baffle 7 is mainly designed to achieve signal isolation between different signal modules; it can be understood that signal isolation is relative, that is, it can isolate only part of the signal interference, and does not mean absolute isolation.

[0064] Furthermore, the positioning device also includes a power interface, which is located on the outer periphery of the housing 1. One end extends into the housing 1 for electrical connection with the circuit board 2, and the other end protrudes from the outer periphery of the housing 1 for electrical connection with an external power source. Specifically, in order to adapt to the specifications of the circuit board, the power interface can be a DC interface with a compatibility voltage of 20V.

[0065] Furthermore, in order to enable the positioning device to connect to multiple computers, the positioning device also includes a local area network (LAN) interface. The LAN interface and the power interface are located on the same side. One end of the LAN interface extends into the housing 1 for electrical connection with the circuit board 2, and the other end protrudes from the outer periphery of the housing 1 for electrical connection with the network cable. Specifically, the LAN interface can be a LAN interface.

[0066] Furthermore, in order to adapt to indoor and outdoor environments, the positioning device also includes a wireless communication interface. The wireless communication interface and the power interface are located on the same side. One end of the wireless communication interface extends into the housing 1 for electrical connection with the circuit board 2, and the other end protrudes from the outer periphery of the housing 1 for electrical connection with the network cable.

[0067] Specifically, the wireless communication interface uses a 433MHz frequency band. The 433MHz signal has strong penetrating power and can pass through walls and other obstacles. Moreover, it is an unlicensed ISM (Industrial, Scientific and Medical) band in most countries. Using a 433MHz interface makes the positioning device described in this disclosure more widely applicable.

[0068] Furthermore, the positioning device also includes a switch, which is disposed on the outer peripheral surface of the housing 1. One end of the switch extends into the housing 1 for electrical connection with the circuit board 2, and the other end protrudes from the outer peripheral surface of the housing 1.

[0069] Furthermore, to facilitate the installation and disassembly of the mobile network antenna module 401, heat dissipation component 5, etc., the housing 102 and the partition 3 are integrally formed.

Unless otherwise stated, these directional terms do not indicate or imply that the device or element 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 on the scope of protection of this disclosure.

[0071] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims disclosed herein.
