Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted central control multimedia display assembly. Background Technology

[0002] As competition intensifies, cost reduction and efficiency improvement have become top priorities for companies, crucial for sustainable operation in today's competitive market economy. The integration of components and the simplification of structures are increasingly becoming trends in the automotive industry. In-vehicle entertainment is becoming increasingly sophisticated, and most central control multimedia assemblies now adopt a split structure, meaning the display assembly and control assembly are designed separately and installed in different locations.

[0003] In existing technologies, display screen assemblies typically employ a three-layer structure design: the central control display screen module assembly is first fixed to a dedicated mid-frame, then the PCB board module is also fixed to this mid-frame, and finally, a rear shell component covers and assembles this assembly, completing the final assembly with the mounting bracket. While this traditional design ensures structural stability and assembly reliability, it also has several significant drawbacks: 1. The use of a mid-frame increases the number of parts and material costs, requiring not only separate mold manufacturing but also additional warehousing and logistics costs; 2. This three-layer structure complicates the assembly process, necessitating multiple workstations and steps on the production line to complete the assembly, impacting overall production efficiency; 3. The presence of the mid-frame also increases the overall weight and volume of the product, hindering lightweight vehicle design; 4. During maintenance, the numerous structural layers make disassembly and component replacement cumbersome. Utility Model Content

[0004] In view of this, it is necessary to provide a simplified in-vehicle central control multimedia display assembly.

[0005] A vehicle-mounted central control multimedia display assembly includes a display module, a PCB board module, and a rear cover. The rear cover covers the rear side of the PCB board module and is fixedly connected to the rear side of the display module. The PCB board module has a plurality of first screw holes, and the display module has corresponding first studs. The PCB board module is fixedly connected to the back of the display module by first screws. The rear cover has a plurality of second screw holes, and the display module has corresponding second studs. The rear cover is fixedly connected to the back of the display module by second screws.

[0006] Based on the concept of cost reduction and efficiency improvement, this utility model removes the middle frame parts and directly assembles the display module and the back shell together by setting the first screw hole, the first stud and the first screw. This fixes the PCB board module to the back of the display module, achieving the effect of fixed assembly. While ensuring the reliability of installation, it also realizes the original function of the product. Furthermore, by reducing the number of parts, it reduces costs and simplifies assembly and maintenance procedures, thereby improving production efficiency. Attached Figure Description

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description is further elaborated in conjunction with the embodiments.

[0015] like Figure 1 , Figure 2 As shown, the in-vehicle central control multimedia display assembly is generally square, and from front to back includes a display module 1, a PCB board module 3, a rear shell 4, and a bracket 5. The PCB board module 3 is fixedly connected to the back of the display module 1 by a first screw 6. The rear shell 4 covers the rear side of the PCB board module 3 and is bonded to the rear edge of the display module 1 by industrial adhesive tape 2. The bracket 5 is fixedly connected to the rear side of the rear shell 4 by a third screw 8. In this embodiment, the in-vehicle central control multimedia display assembly includes two brackets 5 for fixing to the vehicle's instrument panel frame.

[0016] The industrial adhesive tape 2 is used to bond the display module 1 and the back cover 4, ensuring that the display module 1 is assembled flat with uniform gaps and steps, so that its appearance meets the customer's requirements for the A-side. Traditional designs only use tape to bond the display module and the back cover; this embodiment adds four sets of studs and screws, making the connection between the display module 1 and the back cover 4 more secure even without a mid-frame. Figure 3 As shown, the display module 1 includes a backlight module 9 and a touch IC 10. The touch IC 10 is connected to the PCB board module 3 via an FPC cable 11. The backlight module 9 is square in shape and has eight studs on its rear side: four first studs 12 for fixing the PCB board module 3 and four second studs 13 for fixing the display module 1. One second stud 13 is located at each of the four corners of the backlight module 9. The first studs 12 are coupled to the first screws 6 to fix the PCB board module 3 to the back cover 4; the second studs 13 are coupled to the second screws 7 to fix the display module 1 to the back cover 4.

[0017] like Figure 4 As shown, the PCB module 3 is square, with a first screw hole 14 at each of its four corners for mounting the first screw 6 and the first stud 12. The PCB module 3 also has two interfaces: a power interface 15 and an LVDS interface 16. The LVDS interface 16 connects to the corresponding interface of the vehicle's central control display host assembly, receiving display command signals sent by the host to form a complete functional link for the central control multimedia system. Since these two interfaces require a certain amount of force to connect, flexible flat cables cannot be used. Therefore, fixing the PCB module 3 with studs and screws ensures a secure fit while reducing the number of components in the frame compared to traditional designs.

[0018] like Figure 5 , Figure 6As shown, the outer edge of the rear shell 4 is provided with four second screw holes 17 for use with screws 7 to fix the display module 1 to the front side of the rear shell 4; a first through hole 18 and a second through hole 19 are provided at positions corresponding to the power interface 15 and the LVDS interface 16 on the PCB board module 3, respectively, through which the power interface 15 and the LVDS interface 16 protrude to facilitate interface connection; the rear shell 4 is also provided with eight third studs 20 for use with third screws 8 to fix the bracket 5 to the rear side of the rear shell 4. The outer edge of the rear shell 4 is also symmetrically provided with four support legs 21 and two cross-shaped protrusions 22 for assembly positioning, which facilitates the installation process by first positioning the rear shell 4 on the plastic plate on the dashboard, and then fixing the bracket 5 to the dashboard frame with screws. The rear shell 4 is an exterior part, and the surface process requirements of the part are relatively high. The material can be ABS / PC plastic alloy or die-cast aluminum alloy ADC12, and should be coordinated with the requirements of the OEM and the interior of the car.

[0019] like Figure 6 , Figure 7 As shown, the bracket 5 has four third screw holes 24 for engaging with the third screws 8 to fix the bracket 5 to the rear side of the rear housing 4. Each bracket 5 also has two positioning holes 25, and the rear housing 4 has positioning posts 23 at positions corresponding to the positioning holes 25. During installation, aligning the two positioning posts 23 with the positioning holes 25 and inserting them simultaneously ensures the accuracy of the bracket's installation position. The bracket 5 is made of SECC and must meet the OEM's salt spray requirements.

[0020] This invention ingeniously optimizes the structural design of the display assembly. The principle is simple, the parts are simplified, and the product's BOM cost is reduced. It is easy to disassemble and assemble, convenient to maintain, reliable in application, reduces the workload of operators, and improves work efficiency.
