Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, and in particular to a remote communication controller with stable and efficient performance. Background Technology

[0002] With the rapid development of digital and intelligent technologies, remote communication controllers, as key components for realizing remote data interaction and control of equipment, are widely used in many fields such as automobiles, industrial automation, and smart homes. Taking the T-BOX (Telematics Box) in the automotive industry as an example, it undertakes the important task of data communication between the vehicle and the outside world, such as uploading vehicle driving data and fault information in real time, and receiving remote control commands, playing a vital role in improving the vehicle's intelligence level and user experience.

[0003] Most T-BOX products on the market currently use ADC12 die-cast aluminum alloy shells, a material that has revealed several drawbacks in application. From a weight perspective, ADC12 die-cast aluminum alloy has a high density, making the overall product heavy. In the automotive industry, lightweighting is crucial for reducing energy consumption and increasing driving range; an excessively heavy T-BOX is not advantageous. From a cost perspective, ADC12 die-cast aluminum alloy raw materials are relatively expensive, and the die-casting process is complex, involving multiple stages such as mold manufacturing, die-casting equipment use, and subsequent processing, increasing production costs and weakening the product's price competitiveness in the market.

[0004] In terms of product structure, the existing T-BOX is fixed to the host with screws and dissipates heat through the overall shell. This heat dissipation method has the problem of low heat dissipation efficiency. As the functions of T-BOX continue to increase, the internal electronic components generate more heat. Relying solely on the overall shell for heat dissipation is difficult to meet the heat dissipation requirements. This can easily lead to performance degradation, crashes, or even damage due to overheating, affecting the stability and reliability of vehicle remote communication.

[0005] Furthermore, existing products also have shortcomings in electromagnetic shielding and grounding performance. The interior of a car is a complex electromagnetic environment where various electronic devices interfere with each other. The shell materials and structural design of traditional T-BOXs cannot effectively shield against external electromagnetic interference, nor can they provide adequate grounding protection. This may lead to data transmission errors and signal interruptions during T-BOX operation, seriously affecting the quality and security of vehicle remote communication.

[0006] In conclusion, developing a new type of remote communication controller to solve these problems has become an urgent need for the industry. Utility Model Content

[0007] In view of the above-mentioned shortcomings of current remote communication controllers, this utility model provides a remote communication controller with stable and efficient performance, compact structure, good electromagnetic shielding effect and efficient heat dissipation.

[0008] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0009] A remote communication controller includes an upper housing and a lower housing, with a PCB board disposed between the upper and lower housings. A heat-generating electronic component is disposed on the PCB board. The remote communication controller is characterized by having a receiving chamber and a filling chamber. The receiving chamber is formed by a recess in the upper housing, and the filling chamber has a downwardly convex plane of the upper housing. A thermally conductive layer is filled between the heat-generating electronic component and the plane to conduct heat to the upper housing. Heat dissipation fins are disposed on the outer side of the upper housing at corresponding positions to the filling chamber.

[0010] According to one aspect of the present invention, the remote communication controller further includes a battery disposed in the first chamber.

[0011] According to one aspect of the present invention, the battery has a battery cover, which secures the battery by closing the opening of the receiving chamber with a battery cover screw.

[0012] According to one aspect of this utility model, the upper housing is made of ADC12 die-cast aluminum alloy, and the lower housing is made of aluminum plate.

[0013] According to one aspect of this utility model, locking strips are provided on both the left and right sides of the lower housing, and during installation, the locking strips hold the PCB board in the middle.

[0014] According to one aspect of the present invention, a limit post and a limit tooth are provided on the rear edge of the lower surface of the upper housing.

[0015] According to one aspect of this utility model, the thermally conductive material of the thermally conductive layer is thermally conductive silicone grease, thermally conductive gel, thermally conductive pad, or graphene thermally conductive film.

[0016] According to one aspect of the present invention, the remote communication controller further includes a connector interface surface integrally connected to the lower housing, and the connector interface surface is provided with a connector interface.

[0017] According to one aspect of the present invention, a slot is provided on the upper side of the connector interface surface, and a buckle that cooperates with the slot is provided at a corresponding position on the lower surface of the upper housing.

[0018] According to one aspect of this utility model, the upper housing, PCB board and lower housing are fixed by housing screws.

[0019] The advantages of this invention are as follows: First, compared to traditional shell-based heat dissipation, the heat-generating area utilizes heat dissipation fins and high thermal conductivity materials. This heat dissipation method can quickly and effectively dissipate the heat generated by the heat-generating chip, effectively controlling the temperature and improving product stability and reliability. Second, compared to traditional communication controllers using die-cast aluminum alloy shells for the ADC12, the lower shell of this controller design uses 0.8mm aluminum plate material, reducing product weight and production costs. Simultaneously, the aluminum plate lower shell enhances electromagnetic shielding and grounding performance, effectively reducing the impact of external electromagnetic interference on internal electronic components and improving product safety. Third, through multiple positioning structures such as locking strips, limit posts, and snap-fits, precise installation and stable connection of each component are achieved, thereby ensuring product quality. Finally, the layered integration and built-in battery design achieve a compact layout, reducing size and weight, making it suitable for confined spaces and complex environments.

[0023] Figure 3 This is a schematic diagram of a remote communication controller according to the present invention. Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a remote communication controller includes an upper housing 101 and a lower housing 102, with a PCB board 103 disposed between the upper housing 101 and the lower housing 102.

[0026] The upper shell 101 includes an upper base plate, and three side plates extend downward from the three sides of the upper base plate, namely the front side plate, the left side plate and the right side plate. The three side plates are integrated with the upper base plate, resulting in a compact structure.

[0027] The PCB board 103 houses various electronic components, including resistors, capacitors, inductors, sensors, a controller (MCU), and various chips. These chips include communication chips, memory chips, and power management chips. The MCU, as the core control component, is responsible for handling communication protocols, data processing, and executing control commands. It coordinates the work of various modules, such as receiving sensor data, parsing remote communication commands, and controlling related circuit actions accordingly, thus determining the overall functionality and performance of the controller. Communication chips are crucial for realizing remote communication functions and come in different types depending on the communication method. For example, 4G / 5G communication chips (like Qualcomm's Snapdragon X55) are used to achieve high-speed cellular network communication, enabling the upload of device data to a remote server and the reception of remote commands. Wi-Fi chips (such as Broadcom's BCM4360 series) allow devices to access wireless networks, enabling short-range wireless communication, facilitating data exchange between devices and other devices within the home network, especially in smart home scenarios. Memory chips can store programs, data, and cache temporary information, ensuring device operation and data recording. These include types such as Flash memory, DRAM memory, and EEPROM. Power management chips manage voltage conversion, power protection, and power consumption, ensuring stable power supply to all modules. These include DC-DC converters, LDO regulators, and power monitoring chips. The selection of electronic component models and specifications is based on existing technology and is not specifically limited in this design.

[0028] In the remote communication controller 100 of this design, the heat-generating electronic components mainly refer to the microcontroller (MCU) and communication chip on the PCB board 103. These components generate heat during operation. The microcontroller (MCU), as the core component of the communication controller, continuously switches its transistors during complex tasks such as communication protocol processing, data computation, and control command execution. This process consumes electrical energy and generates heat. Whether it's a cellular network chip implementing 4G / 5G communication or a chip used for Wi-Fi communication, current flows through the chip's internal circuitry during signal modulation, demodulation, and data transmission and reception, generating heat. If this heat cannot be dissipated in time, it will affect the performance of the communication chip, leading to unstable signal transmission, data packet loss, and other problems.

[0029] To achieve efficient heat dissipation, the remote communication controller 100 of this design has a filling chamber 204, in which various heat-generating electronic components on the PCB board 104 are located. Simultaneously, a thermally conductive layer 104 is filled between the heat-generating elements of the PCB board 103 and the inner surface of the upper housing 101, forming a heat conduction path. In practice, the thermally conductive material of the thermally conductive layer 104 can be directly applied or adhered to the chip surface, covering the entire heat-generating area of ​​the PCB board 103 and ensuring tight contact with the upper housing 101 to avoid air gaps that could affect heat dissipation efficiency.

[0030] The thermally conductive material of the thermally conductive layer 104 can be selected from thermally conductive silicone grease, thermally conductive gel, thermally conductive pads, or graphene thermally conductive film, etc. In this embodiment, the thermally conductive material is thermally conductive silicone grease, but other types can be selected as needed.

[0031] To further enhance the contact between the heat-generating electronic components on the PCB board 103 and the upper housing 101, thereby improving heat conduction efficiency, in this embodiment, the inner side of the upper housing 101 has a downwardly protruding plane. The number and position of the protruding planes correspond to the number and position of the heat-generating electronic components on the PCB board 103. Thus, after installation, the heat-generating electronic components are tightly bonded to the downwardly protruding plane on the inner side of the upper housing 101 through the thermally conductive layer 104, achieving efficient and precise heat dissipation. Of course, other spaces within the filling chamber 204 can be further filled with thermally conductive material to enhance the heat conduction effect.

[0032] In this embodiment, based on the number of heat-generating electronic components on the PCB board 103, there are four convex lower planes within the filling chamber 204, including a first convex lower plane 104a2, a second convex lower plane 104b2, a third convex lower plane 104c2, and a fourth convex lower plane 104d2. Correspondingly, there are also four thermally conductive layers 104, including a first thermally conductive layer 104a1, a second thermally conductive layer 104b1, a third thermally conductive layer 104c1, and a fourth thermally conductive layer 104d1. Of course, in practical applications, the number of convex lower planes and the number of thermally conductive layers 104 can be flexibly determined as needed.

[0033] Taking thermal grease as an example, in this embodiment, the thermal grease adopts a pre-formed structure, which is a square sheet that can be directly attached to the chip surface, facilitating standardized production. Simultaneously, there are four pre-formed thermal grease sheets, each corresponding to one of the four main heat-generating components (such as an MCU or communication chip) on the PCB board 103. This ensures that each heat-generating component is equipped with its own sheet, achieving precise heat dissipation.

[0034] In this embodiment, the upper housing 101 is made of ADC12 die-cast aluminum alloy, which has good heat dissipation performance. Meanwhile, to further enhance the heat dissipation effect, heat dissipation fins 105 are provided on the outer side of the upper housing 101 at positions corresponding to the filling chamber 204.

[0035] In this design, the heat-conducting layer 104 conducts heat from the heat-generating electronic components to the upper housing 101. The heat dissipation fins 105 on the outside of the upper housing 101 increase the surface area and accelerate air convection (natural heat dissipation or in conjunction with a fan), further dissipating the heat into the environment to achieve efficient heat dissipation.

[0036] Therefore, the remote communication controller in this design uses the thermal conductive layer 104 and the heat dissipation fins to form a multi-level heat dissipation path of "heat-generating electronic components → thermal conductive layer → metal shell → heat dissipation fins", which greatly improves the heat dissipation efficiency compared with the traditional single shell heat dissipation.

[0037] The thermal grease used in this embodiment will be briefly introduced below:

[0038] Thermal grease is a highly thermally conductive and insulating silicone material, typically composed of silicone polymers, thermally conductive fillers (such as metal oxides and metal powders), and other additives. It possesses excellent thermal conductivity, electrical insulation, and resistance to high and low temperatures, making it suitable for use in electronic devices. It fills the tiny gaps between heat-generating components (such as CPUs and GPUs) and heat sinks or radiators, enhancing heat transfer efficiency and reducing the operating temperature of the heat-generating components. From a type perspective, thermal grease can be categorized into ceramic thermal grease, metallic thermal grease, and carbon nanotube thermal grease, among others.

[0039] Ceramic thermal grease uses ceramic powder (such as alumina and boron nitride) as the main thermally conductive filler. This type of thermal grease has a high thermal conductivity, typically between 3-8 W / (m·K), effectively meeting the heat dissipation needs of mid-to-high-end electronic devices. Its advantages include stable chemical properties, a wide temperature range, resistance to volatilization and aging at high temperatures, and a long service life, making it suitable for equipment operating stably for extended periods, such as server CPU cooling.

[0040] Metal thermal grease uses metal powders (such as silver powder, copper powder, etc.) as thermal fillers. Due to the high thermal conductivity of metals, this type of grease can have a thermal conductivity of 5-12 W / (m·K) or even higher, providing excellent heat dissipation performance. It is often used in devices with extremely high heat dissipation requirements, such as high-end gaming graphics cards and overclocked CPUs. However, the metal powders in metal thermal grease may have a certain degree of conductivity. If too much is applied or spills, it may cause short circuits in electronic components, so extra care must be taken when using it.

[0041] Carbon nanotube thermal grease uses carbon nanotubes as a thermally conductive filler. Carbon nanotubes possess extremely high thermal conductivity, allowing this type of grease to achieve a thermal conductivity exceeding 10 W / (m·K), resulting in excellent heat dissipation. This makes it suitable for specialized electronic devices with stringent heat dissipation requirements, such as high-performance computing chips. However, the currently high cost of carbon nanotube thermal grease limits its widespread adoption.

[0042] As described above, the upper housing 101 is made of ADC12 die-cast aluminum alloy. Meanwhile, in this embodiment, the lower housing 102 is made of aluminum plate with a thickness of 0.8mm. This design combines the advantages of both materials, improving the performance of the communication controller in terms of heat dissipation, cost, and protection. Specifically, ADC12 die-cast aluminum alloy has excellent heat dissipation performance; using this material in the upper housing 101 can efficiently dissipate the heat generated by the heat-generating components on the PCB board 103. Using aluminum plate in the lower housing 102 reduces raw material procurement costs compared to ADC12 die-cast aluminum alloy, and the lighter weight of aluminum plate also significantly reduces the product weight. Simultaneously, the aluminum plate lower housing 102 enhances electromagnetic shielding and grounding performance. When the electronic device is subjected to external electromagnetic interference, the aluminum plate can effectively shield against this interference, reducing its impact on internal electronic components, improving product safety, and ensuring stable operation of the product in complex electromagnetic environments.

[0043] The ADC12 die-cast aluminum alloy used in the upper housing 101 is a widely used cast aluminum alloy material in the industrial field. ADC12 die-cast aluminum alloy mainly contains elements such as aluminum (Al), silicon (Si), copper (Cu), magnesium (Mg), and iron (Fe). The silicon content is typically between 9.6% and 12.0%, which improves the alloy's fluidity, making it easier to fill the mold cavity during die casting and form parts with complex shapes. The copper content is between 1.5% and 3.5%, which enhances the alloy's strength and hardness, improving the material's mechanical properties. The magnesium content is approximately 0.3% to 0.5%, which helps refine the alloy grains, improving the alloy's toughness and corrosion resistance. Due to its excellent casting properties, ADC12 die-cast aluminum alloy is widely used in the manufacture of automotive parts, electronic device housings, and other products.

[0044] The PCB board 103 is sealed inside the upper housing 101 and the lower housing 102. Each of the four corners of the PCB board 103, the upper housing 101, and the lower housing 102 has symmetrically arranged upper housing threaded holes 107c, PCB board threaded holes 107b, and lower housing threaded holes 107a, with the threaded holes corresponding to each other. The upper housing 101, the PCB board 103, and the lower housing 102 are fixed together by housing screws 106. During assembly, the housing screws 106 are screwed into the PCB board threaded holes 107b and the upper housing threaded holes 107c, starting from the lower housing threaded hole 107a, thereby fixing the PCB board 103, the upper housing 101, and the lower housing 102 in place.

[0045] In this embodiment, each of the upper housing 101, PCB board 103, and lower housing 102 is equipped with two screws, and correspondingly, two threaded holes. To enhance the fixing effect, a central threaded hole 112 is also provided in the middle of the upper housing 101, PCB board 103, and lower housing 102, and the fixing effect is further enhanced by screws. Simultaneously, a positioning post 108 is provided between the two upper housing threaded holes 107c in the upper housing 101, and corresponding positioning holes 109 are provided at corresponding positions in the PCB board 103 and lower housing 102. Thus, during assembly, positioning is first achieved through the positioning post 108 and positioning holes 109, facilitating assembly and ensuring assembly accuracy.

[0046] The remote communication controller 100 of this utility model also includes a battery 200, which is disposed within a recessed receiving chamber 203 formed by the upper housing 101. The battery 200 can provide emergency power to the equipment in special circumstances, ensuring the operation of critical functions of the equipment in emergency situations, thereby improving the reliability of equipment operation. In this embodiment, considering factors such as battery performance, safety, and environmental friendliness, a nickel-metal hydride battery is selected for the battery 200; however, other types can be selected according to specific needs.

[0047] In this embodiment, the battery 200 has a battery cover 201, which includes a battery cover body 201a and a guide piece 201b. The battery cover body 201a and the upper housing 101 have mating threaded holes (not shown in the figure). During assembly, the guide piece 201b is inserted into the inner side of the receiving chamber 203 and close to the side wall. Then, the battery cover screw 202 is screwed into the threaded hole to close the opening of the receiving chamber 203, thereby fixing the battery cover 201 inside the receiving chamber 203.

[0048] The remote communication controller 100 of this design also includes a connector interface surface 300, which is located between the upper housing 101 and the lower housing 102, forming the rear panel of the remote communication controller 100. Multiple connector interfaces 301 are provided on the connector interface surface 300, and the connector interfaces 301 correspond to connectors 302 on the PCB board. After assembly, the connectors 302 are exposed through the connector interfaces 301 to facilitate the connection of other devices to the remote communication controller.

[0049] There are various types of standard interfaces, mainly used for data transmission, power supply, and other related functions. These include power interfaces, analog signal interfaces, and communication interfaces. The power interface provides a stable DC power supply to the communication controller; common specifications include 5V and 12V, with the appropriate voltage selected based on the device's power consumption and power requirements. Communication interfaces include Ethernet interfaces (RJ45), USB interfaces, and serial ports.

[0050] In this embodiment, the lower housing 102 and the connector interface surface 300 are integrated, which improves the sealing of the controller 100 and effectively prevents the entry of foreign objects, thereby enhancing its protective performance. At the same time, the integrated molding of the lower housing 102 and the connector interface surface 300 also improves the product's aesthetics and enhances its market competitiveness.

[0051] To facilitate product assembly, the connector interface surface 300 has a slot 303 on its upper side. In this embodiment, there are three slots 303, which are evenly spaced. Correspondingly, a buckle 304 that mates with the slot 303 is provided at a corresponding position on the lower surface of the upper housing 101.

[0052] To ensure the accuracy of the housing installation, the lower surface of the upper housing 101 is provided with a limiting post 111 and a plurality of wedge-shaped limiting teeth 113 on the rear edge. In this embodiment, the limiting post 111 is located at the middle position of the rear edge of the lower surface of the upper housing 101, and there are four limiting teeth 113.

[0053] Meanwhile, retaining strips 401 are provided on both the left and right sides of the lower housing 102, and the upper end of the retaining strips 401 has multiple small teeth. During installation, the retaining strips 401 on the left and right sides can hold the PCB board 103 in the middle, which results in a better assembly effect.

[0054] In this embodiment, the threaded holes 107a at the four corners of the lower housing 102 are countersunk holes relative to the bottom plate of the lower housing 102. This ensures that the screws will not protrude from the bottom plate of the lower housing 102 after screwing them in, thus ensuring the flatness of the bottom plate. At the same time, a reinforcing rib layer 500 is provided on the outer side of the bottom plate. The reinforcing rib layer 500 is fixed to the lower surface of the lower housing 102 by screws, thereby protecting the lower housing 102 and improving the structural strength of the lower housing 102.

[0055] A label 110 is also provided on the outer surface of the upper housing 101. The label 110 can indicate the basic parameters of the controller 100, explain the electrical parameters, and may also include safety warning signs to remind operators to comply with safety regulations. The label 110 can be affixed to the outer surface of the upper housing 101 with double-sided adhesive.

[0056] Meanwhile, for easy fixation, the remote communication controller 100 of this utility model is also provided with a bracket. In this embodiment, the bracket includes a left bracket 400b and a right bracket 400a, both of which are located at the bottom of the lower housing 102 and can be fixed with screws. The heads of both the left bracket 400b and the right bracket 400a are provided with threaded holes, including a left threaded hole 401b and a right threaded hole 401a. In use, the controller 100 can be fixed to the corresponding equipment by screwing in the bolts.

[0057] The advantages of this invention are as follows: First, compared to traditional shell-based heat dissipation, the heat-generating area utilizes heat dissipation fins and high thermal conductivity materials. This heat dissipation method can quickly and effectively dissipate the heat generated by the heat-generating chip, effectively controlling the temperature and improving product stability and reliability. Second, compared to traditional communication controllers using die-cast aluminum alloy shells for ADC12 chips, the lower shell of this controller design uses 0.8mm aluminum plate material, reducing product weight and production costs. Simultaneously, the aluminum plate lower shell enhances electromagnetic shielding and grounding performance, effectively reducing the impact of external electromagnetic interference on internal electronic components and improving product safety. Third, through multiple positioning structures such as locking strips, limit posts, and snap-fits, precise installation and stable connection of each component are achieved, thereby ensuring product quality. Finally, the layered integration and built-in battery design achieve a compact layout, reducing size and weight, and adapting to confined spaces and complex environments. In conclusion, this invention's remote communication controller has value for large-scale industrial application.

[0058] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
