Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted integrated display machines, and in particular to a vehicle-mounted integrated display machine with a micro-frame. Background Art

[0002] In today's digital information age, car displays are getting closer and closer to consumer-grade mobile phones and computer products. Based on a series of requirements such as vehicle safety and service life, the borders of traditional car displays have an obvious black border, which not only leads to the embarrassing situation that the screen looks large in appearance but the actual displayed content is small. This not only causes sensory discomfort to the driver and passengers, but also affects the operation during human-computer interaction.

[0003] Compared with traditional car displays, the existing technology has proposed micro-border display technology, which has a more prominent visual effect and can provide users with a wider field of view. If such micro-border display can be applied to the all-in-one car display, it can greatly improve the satisfaction of the driver and passengers and the comfort of immersive driving.

[0004] However, the existing micro-border display technology is generally used in desktop or portable consumer electronics fields. Due to the special environment in which in-vehicle electronic products are located, bumps and vibrations will occur when the vehicle is driving. Therefore, they need to have certain impact and vibration resistance capabilities. Blindly using the existing micro-border display in a vehicle environment may cause problems such as screen cracking and falling off. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a vehicle-mounted micro-frame display all-in-one machine is provided, which includes: a narrow-edge front frame, a rear frame, a display screen unit, a screen drive board, a mainboard unit, and a shell, wherein the display screen unit includes: a touch screen and a display screen, wherein the touch screen includes: a transparent plastic layer and a SENSOR glass, wherein the transparent plastic layer and the SENSOR glass are pressed together by LOCA glue, and the touch screen is bonded to the display screen by an OCA optical adhesive strip; the narrow-edge front frame body extends backward with a card edge A buckle is arranged on the card edge, a card slot is arranged around the rear frame, a card convex is arranged in the card slot, a bearing platform is arranged on the first side of the card slot, and a bearing frame is arranged on the second side, and there is a drop between the bearing frame and the bearing platform. The narrow-edge front frame is clamped on the edge side of the display screen unit, and is inserted into the card slot of the rear frame through its card edge so that the buckle is engaged with the card convex to limit the display screen unit on the rear frame bearing platform. The screen driving board is fixed on the bearing frame and connected to the display screen unit. The mainboard unit is connected to the back of the rear frame. The shell is connected to the rear frame, and the cover is connected to the outside of the mainboard unit.

[0007] Preferably, the transparent plastic layer is made of any one of transparent PC and PET films.

[0008] Preferably, the vehicle-mounted micro-frame display integrated machine further includes: a metal grounding sponge, wherein the metal grounding sponge is sandwiched between the back of the display screen and the rear frame supporting platform.

[0009] Preferably, the vehicle-mounted micro-frame display all-in-one machine also includes: a front-end interface unit, wherein an interface slot is provided on the third side of the rear frame to accommodate the front-end interface unit, an interface cover extends from one side of the transparent plastic layer of the touch screen to cover the interface slot, and an interface window corresponding to the interface of the front-end interface unit is provided on the interface cover, and the front-end interface unit is connected to the mainboard unit.

[0011] The vehicle-mounted micro-frame display all-in-one provided by the utility model cleverly designs the stacked compression and impact-resistant structure of the display screen unit to form a semi-flexible display screen unit, so as to adapt to the connection structure of the narrow-edge front frame and the rear frame, and can prevent the relatively fragile SENSOR glass from breaking during the clamping process, thereby increasing the visible and interactive range of the display screen unit. On the other hand, in the corresponding implementation method, the SENSOR glass is clamped by utilizing the deformable and compressible plasticity of the PC or PET film itself, and the interlayer design characteristics of the LOCA glue and the OCA optical adhesive strip, which can greatly reduce the impact force and vibration force on the SENSOR glass, and can also partially release the thrust in the downward process, thereby solving the problem that the existing micro-frame display screen is used in a vehicle-mounted environment and causes the screen to crack and fall off.

And one or more of the components in the diagram may be necessary or non-essential, and the relative position relationship between the components in the above diagram can be adjusted according to actual needs.

[0029] See also Figures 1 to 9As shown, the utility model provides a vehicle-mounted micro-frame display all-in-one, which includes: a narrow-edge front frame 1, a rear frame 2, a display screen unit 3, a screen driving board 4, a main board unit 5, and a shell 6, wherein the narrow-edge front frame 1 has a card edge 11 extending backward from the frame body, and a buckle 12 is arranged on the card edge 11, and a card slot 21 is arranged around the rear frame 2, and a card convex 22 is arranged in the card slot 21, and a first side of the card slot 21 is provided with a bearing platform 23, and a second side is provided with a bearing frame 24, and the bearing frame 24 has a drop with the bearing platform 23, the narrow-edge front frame 1 is clamped on the edge side of the display screen unit 3, and the card edge 11 thereof is inserted into the card slot 21 of the rear frame 2 so that the buckle 12 is buckled with the card convex 22, so as to limit the display screen unit 3 on the bearing platform 23 of the rear frame 2, the screen driving board 4 is fixed on the bearing frame 24, and is connected to the display screen unit 3, the main board unit 5 is connected to the back of the rear frame 2, and the shell 6 is connected to the rear frame 2, and the cover is connected to the outside of the main board unit 5.

[0030] Specifically, the traditional narrow-border display screen 32 is usually directly bonded to the electronic product by bonding. However, in the field of vehicle-mounted electronics, the temperature inside the car is high under direct sunlight in summer, so the bonding solution cannot be used. The narrow-border front frame 1 and the rear frame 2 are connected by snapping 12, which is easy to damage the display screen unit 3. The reason is that the traditional display screen unit 3 is generally composed of a touch screen 31 and a display screen 32, and the touch screen 31 is generally composed of an upper tempered glass and a lower sensor glass 312. When the narrow-border front frame 1 and the rear frame 2 are clamped together and clamped around the edge of the touch screen 31, the tempered glass will be squeezed. The lower sensor glass 312 is relatively fragile and is easy to break during the clamping process. At the same time, when the narrow-border front frame 1 is tightly pressed, the vibration caused by the bumps of the vehicle will also increase the risk of the sensor glass 312 breaking.

[0031] Therefore, in order to solve the above problems, Figure 4 As shown, the utility model illustrates a display screen unit 3, which includes: a touch screen 31, a display screen 32, wherein the touch screen 31 includes: a transparent plastic layer 311, a SENSOR glass 312, wherein the transparent plastic layer 311, in an optional example, can be made of any material of transparent PC or PET film to replace the tempered glass, and is pressed together with the SENSOR glass 312 via LOCA glue, and the touch screen is bonded to the display screen 32 via OCA optical adhesive strips, thereby constructing a semi-flexible display screen unit 3.

[0032] Through this arrangement, the deformable and compressible plastic properties of the PC or PET film are utilized to cover the lower layer of the SENSOR glass 312, so that a flexible buffer is formed between the SENSOR glass 312 and the narrow-edge front frame 1 by the transparent plastic layer 311, thereby preventing the SENSOR glass 312 from being damaged by pressure. In addition, in view of the stacked and bonded structural design of the display screen unit 3 in the above example, the SENSOR glass 312 has certain buffering properties at the front and back, thereby effectively reducing the impact force and vibration force on the lower layer of the SENSOR glass 312, and partially releasing the thrust in the downward pressing process.

[0033] In addition, Figure 3 to Figure 4 As shown, in order to further reduce the thrust that the lower layer of SENSOR glass 312 may be subjected to during the downward pressing process of the narrow-edge front frame 1, in an optional embodiment, the vehicle-mounted micro-frame display all-in-one machine also includes: a metal grounding sponge 7, wherein the metal grounding sponge 7 is clamped between the back of the display screen 32 and the supporting platform 23 of the rear frame 2.

[0034] like Figure 4 As shown, a metal grounding sponge 7 is pasted between the inside of the rear frame 2 and the bottom surface of the display unit 3 near the snap-in position to unload and release the secondary downward thrust. This fixing method fills the gap between the display unit 3 and the bearing platform 23 of the rear frame 2, while preventing the transmission of vehicle vibration, avoiding the tightening force when the narrow-edge front frame 1 is pressed down, allowing the buckle 12 to smoothly enter the snap-in position to complete the fixation. This solves the problem that the existing micro-frame display screen 32 used in a vehicle environment will cause the screen to crack and fall off.

[0035] On the other hand, in an optional embodiment, in order to facilitate access to the USB interface or memory card slot from the front end of the vehicle, such as Figure 1 , Figure 3 , Figure 6 As shown, the vehicle-mounted micro-frame display all-in-one machine also includes: a front-end interface unit 8, wherein the third side of the rear frame 2 is provided with an interface slot 25 to accommodate the front-end interface unit 8, and an interface cover 313 extends from one side of the transparent plastic layer 311 of the touch screen 31 to cover and conceal at least part of the interface slot 25, and the interface cover 313 is provided with an interface window 314 corresponding to the interface of the front-end interface unit 8, such as a USB interface window and a memory card insertion window, and the front-end interface unit 8 is connected to the mainboard unit 5.

[0036] On the other hand, in an optional embodiment, in order to improve the heat dissipation effect of the mainboard unit 5 and comply with mandatory regulations such as EMC, a notch is provided on the first side of the mainboard unit 5 in this example, and a high-heat device on the mainboard unit 5, such as a MOS field effect transistor 51, can be arranged next to the notch and extend into the notch, and a heat dissipation hole 61 and a heat conducting platform 62 are provided on the shell 6, wherein the heat conducting platform 62 is arranged at a position corresponding to the notch of the mainboard unit 5 and is in a boss shape for contact with the high-heat device, thereby directing its heat to the shell 6 for heat dissipation. On the other hand, natural convection of air can be introduced through the heat dissipation hole 61 on the shell 6, effectively avoiding the concentrated accumulation of heat in the shell 6, improving the heat dissipation effect of the high-heat device of the mainboard unit 5, and enhancing the overall product performance.

[0037] In summary, through the vehicle-mounted micro-frame display all-in-one provided by the utility model, the stacked compression and impact-resistant structure of the display screen unit 3 is cleverly designed to form a semi-flexible display screen unit 3, so as to adapt to the connection structure of the narrow-edge front frame 1 and the rear frame 2, and can prevent the relatively fragile SENSOR glass 312 from breaking during the clamping process, thereby increasing the visible and interactive range of the display screen unit 3. On the other hand, in the corresponding implementation, the SENSOR glass 312 is clamped by utilizing the deformable and compressible plasticity of the PC or PET film itself, and the interlayer design characteristics of the LOCA glue and the OCA optical adhesive strip, which can greatly reduce the impact force and vibration force on the SENSOR glass 312, and can also partially release the thrust in the downward process, thereby solving the problem that the existing micro-frame display screen 32 is used in a vehicle-mounted environment, which will cause the screen to crack and fall off.
