Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a layout structure of an in-vehicle host, an in-vehicle host and a vehicle. Background Art

[0002] In the current wave of automotive intelligence, the in-vehicle host, as the core component of the automotive information system, has witnessed rapid technological development. However, with the increasing diversification of the automotive market and the individualization of consumer demands, different vehicle models have emerged in large numbers, posing unprecedented challenges to the design and production of in-vehicle hosts. In the prior art, a significant problem commonly faced by in-vehicle hosts is the complexity of vehicle model adaptation. Due to differences in the cockpit layout, electrical architecture, and functional requirements of each vehicle model, the size, shape, and even the functional modules to be integrated in the in-vehicle host vary greatly.

[0003] For the primary suppliers of the host, this diverse demand directly leads to a high degree of customization in host design. Whenever a new vehicle model project is launched, the supplier needs to redesign the host to meet specific requirements. This process not only involves complex software and hardware integration but also incurs high mold development costs, often reaching hundreds of thousands of yuan or more for each project. In addition, frequent design changes not only increase the difficulty of project management but also significantly elevate the quality risk, as each design adjustment may introduce new defects.

[0039] As Figure 2 and Figure 3 shown, the end cover 30 is arranged on the main frame 10, and a third limiting member 13 is arranged on the end cover 30; Exemplarily, the end cover 30 is fixedly arranged on the main frame 10 by means of snap connection, bolt connection or gluing, etc. Exemplarily, the end cover 30 is arranged on the main frame 10 to block an opening on one side of the main frame 10, which can prevent sundries from entering the main frame 10 and can avoid the parts inside the main frame 10 from being knocked.

[0040] Exemplarily, the third limiting member 13 can provide an installation position for the wireless communication module 40. Exemplarily, the second limiting member 12 is a bracket fixedly arranged on the end cover 30 by means of snap connection, bolt connection, integral molding or gluing, etc.

[0041] The wireless communication module 40 is electrically connected to the main circuit board 20, and the wireless communication module 40 is at least installed on one of the first limiting member 11, the second limiting member 12 and the third limiting member 13.

[0042] As Figure 2 shown, Exemplarily, one wireless communication module 40 is arranged, and the wireless communication module 40 is arranged on the first limiting member 11. As Figure 5 shown, in some other embodiments, one wireless communication module 40 is arranged, and the wireless communication module 40 is arranged on the second limiting member 12. As Figure 3 and Figure 5 shown, in some other embodiments, one wireless communication module 40 is arranged, and the wireless communication module 40 is arranged on the third limiting member 13.

[0043] In another embodiment, two wireless communication modules 40 are provided. One wireless communication module 40 is disposed on the first limiting member 11, and the other wireless communication module 40 is disposed on the second limiting member 12. In some other embodiments, two wireless communication modules 40 are provided. One wireless communication module 40 is disposed on the first limiting member 11, and the other wireless communication module 40 is disposed on the third limiting member 13. In another embodiment, two wireless communication modules 40 are provided. One wireless communication module 40 is disposed on the second limiting member 12, and the other wireless communication module 40 is disposed on the third limiting member 13.

[0044] In another embodiment, three wireless communication modules 40 are provided, and one wireless communication module 40 is disposed on each of the first limiting member 11, the second limiting member 12, and the third limiting member 13.

[0045] Exemplarily, the wireless communication module 40 includes but is not limited to: a cellular communication module, a Wi-Fi module, a Bluetooth module, a ZigBee module (ZigBee Wireless Module), a LoRa (Long Range) module, an NB-IoT (Narrowband Internet of Things) module, a UWB (Ultra-Wideband) module, an RFID (Radio Frequency Identification) module, an infrared communication module, a satellite communication module, an RF wireless data communication module, or a 2.4GHz wireless transceiver module, etc.

[0046] By providing the first limiting member 11, the second limiting member 12, and the third limiting member 13, multiple installation methods for the wireless communication module 40 are provided, including the installation of a single or multiple modules, and different installation positions can be selected according to needs. This flexibility enables the in-vehicle host to be configured according to different application scenarios and communication requirements, enhancing the adaptability and market competitiveness of the product. The multiple installation methods of the wireless communication module 40 provide different host layout structures for the in-vehicle host, improving the ability of the in-vehicle host to be compatible with different vehicle models, reducing the development cost of new models of in-vehicle hosts, enhancing the quality stability of the host, and reducing the project management difficulty and production cost.

[0047] As Figure 3 shown, in one embodiment, a bottom cover 18 is provided on the main frame 10, and the bottom cover 18 is fixedly arranged at the opening on the main frame 10 by means of welding, snap connection, gluing, or bolt connection, etc.

[0048] As Figure 3 or Figure 7As shown, in one embodiment, at least two host circuit boards 20 are provided. The at least two host circuit boards 20 are arranged in parallel with each other and distributed in sequence along a first direction, and the first direction is perpendicular to the plane where the host circuit board 20 is located. Exemplarily, the plane where the host circuit board 20 is located is parallel to the plane of the bottom wall of the slot of the mainframe rack 10. Exemplarily, the side wall of the slot of the mainframe rack 10 and the bottom wall of the slot are perpendicular to each other or have an included angle less than 90°. Exemplarily, the plate body and the dowel pin for the host circuit board 20 are provided on the slot wall of the mainframe rack 10, so that the host circuit board 20 is fixedly arranged on the mainframe rack 10 by means of bolt connection, snap connection or gluing. By arranging the host circuit boards 20 in parallel with each other and distributing them in sequence along the first direction, the space of the mainframe rack 10 can be utilized maximally. This layout makes the connection and wiring between the circuit boards more compact and orderly, and at the same time reduces unnecessary space waste.

[0049] It should be understood that at least two host circuit boards 20 are provided. The circuit structures between the host circuit boards 20 can be the same or different. When the circuit structures between the host circuit boards 20 are the same, they can be used as spares for each other. This means that if one of the circuit boards fails, another or more circuit boards can take over the work, thus ensuring the continuity and stability of the system and improving the overall reliability and safety performance.

[0050] When the circuit structures between the host circuit boards 20 are different, the functions of the host can be enriched. Different circuit boards can be responsible for different functional modules, so that the whole system can support more complex and diverse application scenarios. At the same time, this design also increases the flexibility of the system, and the circuit boards can be adjusted and replaced according to actual needs.

[0051] Exemplarily, the area size of the host circuit board 20 can be set according to the actual engineering needs.

[0052] Exemplarily, as Figure 3 or Figure 7 shown, two host circuit boards 20 are provided. In some other embodiments, three host circuit boards 20 are provided. In another embodiment, five host circuit boards 20 are provided.

[0053] As Figure 3 and Figure 5 shown, in one embodiment, a first protective case 14 is provided on the mainframe rack 10. When the wireless communication module 40 is installed on the first limiting member 11, the wireless communication module 40 is provided with a stainless steel antenna, and the stainless steel antenna is arranged in the first protective case 14.

[0054] The first protective shell 14 provides a physical barrier for the stainless-steel antenna, which can effectively prevent the antenna from being physically impacted, worn, or corroded by the external environment during transportation, installation, or use. This helps to extend the service life of the antenna and reduce system failures caused by antenna damage.

[0055] Exemplarily, the first protective shell 14 is made of plastic. Plastic generally has good insulation properties, which helps to reduce the impact of electromagnetic interference on the antenna signal. Although the stainless-steel antenna itself has a certain resistance to electromagnetic interference, the additional insulation layer of the plastic protective shell can further improve the signal stability.

[0056] As Figure 5 shown, in one embodiment, when the wireless communication module 40 is installed on the end cap 30, the wireless communication module 40 is provided with a wireless communication circuit board and a wireless communication antenna. The wireless communication circuit board is electrically connected to the host circuit board 20 and the wireless communication antenna, and the wireless communication antenna is disposed on the end cap 30. Disposing the wireless communication antenna on the end cap 30 can ensure that the antenna works in a good receiving and transmitting environment. The end cap 30 is fixed to the outside of the main frame 10 and is less affected by internal electronic components, which helps to improve the stability and reliability of wireless communication.

[0057] Exemplarily, the wireless communication circuit board is separately disposed from the host circuit board 20, and the wireless communication circuit board can be disposed on the end cap 30 or the main frame 10. The separate arrangement of the wireless communication circuit board and the host circuit board 20 makes the wireless communication module 40 a relatively independent unit. When maintenance or upgrade of the wireless communication function is required, the wireless communication module 40 can be operated independently without affecting other parts of the host circuit board 20, greatly improving the convenience of maintenance and the flexibility of upgrade.

[0058] In another embodiment, the wireless communication circuit board is integrated into the host circuit board 20, which helps to reduce space occupancy and cost, and is suitable for application scenarios with strict space requirements or cost sensitivity.

[0059] As Figure 6 and Figure 7 shown, in one embodiment, the in-vehicle host layout structure further includes a wired communication module. The wired communication module is disposed on the host circuit board 20, and the connection terminal 21 of the wired communication module is fixedly disposed on the main frame 10, and the connection terminal 21 is disposed opposite to the end cap 30.

[0060] Exemplarily, a terminal fixing member 19 is provided on the main frame 10. The terminal fixing member 19 is fixedly arranged on the main frame 10 by means of welding, gluing, snap connection or bolt connection, etc. Exemplarily, the connection terminal 21 is fixedly arranged on the main frame 10 through the terminal fixing member 19, and the connection terminal 21 is fixedly arranged on the terminal fixing member 19 by means of snap connection, gluing or bolt connection, etc.

[0061] Exemplarily, the vehicle-mounted host is electrically connected to an external device through a wired communication module.

[0062] Exemplarily, the wired communication module includes, but is not limited to: an Ethernet module, a USB (Universal Serial Bus) module, a serial port module, an IEEE1394 / FireWire module or an optical fiber communication module, etc.

Of course, other quantities of batteries can also be provided. For example, six batteries are provided, and two battery modules are provided on each of the first mounting member 15, the second mounting member 16 and the third mounting member 17.

[0072] Exemplarily, the battery capacity of the battery module is 600 mAh or 1200 mAh. Of course, the battery capacity of the battery module can also be other sizes, such as 1800 mAh, 2000 mAh, etc.

[0073] As shown Figure 6 or Figure 8As shown, in one embodiment, the in-vehicle host layout structure further includes a fixing plate 50. The fixing plate 50 is an L-shaped plate structure and is disposed on the outer wall of the groove wall of the main frame 10.

[0074] At least two mounting through holes are provided on the fixing plate 50. Exemplarily, two mounting through holes are provided on the fixing plate 50. In some other embodiments, four mounting through holes are provided on the fixing plate 50. In some other embodiments, six mounting through holes are provided on the fixing plate 50. In some other embodiments, eight mounting through holes are provided on the fixing plate 50. It can be understood that the distribution locus of the mounting through holes provided on the fixing plate 50 has a certain regularity. For example Figure 8 As shown, the fixing plate 50 is an L-shaped plate structure formed by vertically connecting a first plate body and a second plate body. Eight first mounting through holes are provided. Two first mounting through holes are provided on the first plate body, and the two mounting through holes on the first plate body are located at both ends of the first plate body. Six first mounting through holes are provided on the second plate body. The six first mounting through holes are evenly divided into two groups.

Of course, the first mounting through holes can also be distributed according to other rules. For example, the first mounting through holes are distributed along a straight-line locus.

[0075] Exemplarily, an assembly hole 51 is provided on the main frame 10. The fixing plate 50 is fixedly disposed on the main frame 10 through a bolt, and the bolt is in threaded fit with the assembly hole 51 and the mounting through hole.

[0078] A limiting boss 23 is provided on the main circuit board 20. At least one processor 22 is provided on the limiting boss 23. The air inlet of the wind guiding housing is disposed at the limiting boss 23.

[0079] Setting the fan 60 at the air outlet of the air guiding housing can significantly improve the heat dissipation efficiency of the host. The active exhaust function of the fan 60 combined with the air duct design of the air guiding housing can more effectively take away the heat generated by heat generating components such as the processor 22, thereby avoiding damage to the internal components of the host caused by high temperature and extending the service life.

[0080] The air inlet of the air guiding housing is directly set at the limiting boss 23, that is, above or near the processor 22, realizing direct collection and discharge of heat. This design makes heat dissipation more accurate and efficient, and can focus on heat dissipation for key components with large heat generation to ensure the stable operation of the entire system.

[0081] The reasonably designed air guiding housing and air duct can reduce the turbulence and eddy current when the air flow passes through, thereby reducing the noise generated when the fan 60 operates. This is of great significance for enhancing the driving experience and maintaining the quiet and comfortable environment in the vehicle.
