Description

Technical Field

[0001] The utility model belongs to the technical field of automotive parts and relates to an in-vehicle MP5 integrated machine with a built-in T-BOX function. Background Art

[0002] With the continuous development of automotive electronic technology, the in-vehicle multimedia system has gradually become an indispensable part of modern vehicles. In order to provide more abundant functions and better user experience, the integration degree of the in-vehicle multimedia system is constantly improved. However, in the existing implementation solutions, the T-BOX function is usually realized through an independent ECU host and is equipped with an external 4G antenna. Although this design can meet the basic requirements, it brings problems such as high complexity of the vehicle system, low integration degree, and relatively high cost.

[0003] Specifically, the current implementation solutions include the following aspects: (1) The independent ECU host with the T-BOX function and the independent central control multimedia MP5 result in a low integration degree of the vehicle system, leading to an increase in system complexity; (2) The external placement of the 4G antenna increases the cost of wiring harnesses and connectors and also increases the complexity of product installation in the vehicle; (3) Each module is fixed on the PCB using an independent shielding cover, which increases the cost of the shielding cover and also improves the difficulty of assembly.

[0004] In order to reduce the material cost of the vehicle, reduce the number of vehicle parts, and optimize the vehicle system, the vehicle factory has put forward the requirement of integrating the independent ECU host with the T-BOX function and the external 4G antenna into the MP5 host. Although the proposal of this requirement can effectively improve the integration degree of the system and reduce the cost, it also increases the difficulty of the structural design of the MP5 host. Therefore, it is necessary to design a brand-new structural solution to adapt to this integration requirement and ensure the stability and performance of the system. The technical challenges in this context have given rise to the need for innovative structural designs, so as to achieve a structural solution for the in-vehicle multimedia integrated machine with a built-in T-BOX function that has low cost and high integration degree.

The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0030] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0031] To achieve the above object, an embodiment of the present utility model provides an in-vehicle MP5 all-in-one machine with an in-built T-BOX function. Referring to Figures 1-10 as shown, it includes a rear shell 1, a touch screen assembly 2, a die-casting heat dissipation frame 3, a main control board 4, a T-BOX signal assembly, and a power supply device. The touch screen assembly 2 is tightly covered on the rear shell 1. The rear shell 1 is provided with a special-shaped hole. The rear part of the die-casting heat dissipation frame 3 passes through the special-shaped hole and is installed and connected inside the rear shell 1. The main control board 4 is installed on the die-casting heat dissipation frame 3. The T-BOX signal assembly is arranged on the side of the die-casting heat dissipation frame 3. A detachable power supply device is arranged on the outer side of the rear part of the die-casting heat dissipation frame 3. The main control board 4 is electrically connected to the touch screen assembly 2, the T-BOX signal assembly, and the power supply device.

[0032] In the prior art, the T-BOX function is usually implemented by an independent ECU host and used in conjunction with an independent central control multimedia MP5. This decentralized structure results in a relatively high complexity of the vehicle system. Among them, each module in the independent ECU host and the central control multimedia MP5 usually requires an independent shielding cover and connection harness, resulting in a low system integration level. Coupled with the use of an external 4G antenna and its connection harness and connectors, the material cost and assembly difficulty of the product are increased, making it difficult to apply, promote, and implement. Based on this, in this embodiment, a die-cast heat dissipation frame 3 is arranged on the rear shell 1 of the in-vehicle MP5, and a main control board 4, a T-BOX signal component, and a power supply device are integrally arranged on the die-cast heat dissipation frame 3. The T-BOX signal component has functions of enhancing signals and wireless communication connection. It is built into the in-vehicle MP5 and connected to the main control board 4 to form an integrated connection with multiple functions, optimizing the overall performance and processing energy efficiency. Moreover, the die-cast heat dissipation frame 3 itself is subjected to signal interference shielding treatment. By directly corresponding to assemble and fit-fix the main control board 4, the shielding of EMC interference can be achieved, greatly simplifying the assembly difficulty, improving the overall assembly efficiency, with reasonable and effective function integration, low cost, and high integration level, meeting the requirements of the in-vehicle MP5.

[0033] Among them, the T-BOX signal component includes a T-BOX integrated board 5 and a BT antenna board 6. The T-BOX integrated board 5 is arranged on one side of the die-cast heat dissipation frame 3, and the BT antenna board 6 is arranged on the other side of the die-cast heat dissipation frame 3. The main control board 4 is electrically connected to the T-BOX integrated board 5 and the BT antenna board 6. Among them, the T-BOX integrated board 5 is an integration of 4G / 5G + Wi-Fi, and the BT antenna board 6 is used to enhance the signal strength.

[0034] The ECU host (Electronic Control Unit) of the T-BOX function is a key component in the vehicle information system, which is mainly used to implement telematics and communication functions. The T-BOX (Telematics Box) is essentially a vehicle information processing module responsible for data interaction between the vehicle and the external network. The T-BOX integrated board 5 adopted in this embodiment is an integration of 4G / 5G + Wi-Fi, including some functions that allow users to control the vehicle through a mobile phone or other remote devices, such as remote start, door lock / unlock, air conditioning control, etc. Through the GPS module, the T-BOX can real-time locate the vehicle and send the location information to the cloud or the user's device for anti-theft or monitoring. The 4G / 5G module in the T-BOX is used for connection to the external network to realize functions such as in-vehicle Wi-Fi hotspot and real-time traffic information acquisition.

[0035] The BT antenna board 6 (Bluetooth antenna board) is used to implement the Bluetooth communication function between the in-vehicle multimedia system and external devices. The design of the BT antenna board 6 can enhance the receiving and transmitting capabilities of Bluetooth signals, ensure signal stability and transmission distance, enabling the in-vehicle multimedia system to establish a wireless connection with external devices (such as smartphones, tablets, etc.). This connection allows users to play music via Bluetooth, make hands-free calls, transfer data, etc., thereby enhancing the wireless connection experience of users in the vehicle. Furthermore, the integrated design of the BT antenna board 6 helps to simplify the structural layout and avoid the use of external antennas. This design not only saves space but also reduces the use of external connectors and wiring harnesses, thus reducing costs and assembly difficulties.

[0036] Furthermore, referring to Figures 3-5 As shown, a first positioning point 7 is provided on one side of the die-cast heat dissipation frame 3, and a second positioning point 8 is provided on the other side. A first positioning groove 9 is provided at the bottom of the T-BOX integrated board 5, and a second positioning groove 10 is provided at the bottom of the BT antenna board 6. The first positioning groove 9 is sleeved with the first positioning point 7, and the second positioning groove 10 is sleeved with the second positioning point 8, so that the T-BOX integrated board 5 and the BT antenna board 6 can be quickly positioned and installed and fixed.

[0037] Furthermore, referring to Figures 6-7 As shown, a number of shielding frames 11 are integrally connected inside the die-cast heat dissipation frame 3. A number of electronic modules corresponding to the shielding frames 11 are provided at the rear of the main control board 4. A conductive soft coating 12 is coated on the upper surface of the shielding frame 11 to make the main control board 4 fit with the shielding frame 11 for shielding EMC interference.

[0038] In this embodiment, a number of electronic modules are provided on the back of the main control board 4, such as chip components, power amplifier components, electronic components, etc. When installing the main control board 4, a conductive soft coating 12 is coated on the upper surface of the shielding frame 11, and the electronic modules on the main control board 4 are correspondingly sleeved into the shielding frames 11 in the die-cast heat dissipation frame 3, making the main control board 4 fit more closely with the shielding frame 11, so as to shield EMC interference. The shielding frames 11 in the die-cast heat dissipation frame 3 are designed to replace the traditional single independent shielding cover, reducing the product assembly stations, saving assembly time, saving the material cost of the independent shielding cover, and enabling a die-cast heat dissipation frame 3 to have multiple functions and uses.

[0039] Furthermore, referring to Figure 2As shown, the touch screen assembly 2 includes a front shell 17, a display screen 14, a screen pressing plate 15, and a touch screen panel 16. The rear shell 1 is connected with the front shell 17. The front shell 17 is provided with a mounting hole 13, and the display screen 14 is arranged in the mounting hole 13.

Then, the combined touch screen panel 16 and display screen 14 are installed on the front end surface of the front shell 17 and fixed by means of snap connection.

[0040] Further, referring to Figures 9-10 As shown, the power supply device includes a nickel-metal hydride battery 18 and a battery cover 19. A battery slot 20 is provided at the rear part of the die-casting heat dissipation frame 3. The nickel-metal hydride battery 18 is arranged in the battery slot 20.
