Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an automotive display device with heat dissipation function. Background Technology

[0002] Automotive displays are crucial indicators of vehicle status, conveying key information to the driver through different colors and patterns of light. Timely understanding and processing of this information effectively ensures driving safety and extends the vehicle's lifespan. However, automotive displays generate significant heat during operation, necessitating a design with effective heat dissipation capabilities.

[0003] Currently, automotive display devices mainly include: one-way mirrors, semi-transparent mirrors, and LED light strips. The LED light strips are installed on the side wall between the one-way mirror and the semi-transparent mirror. The light emitted by the LED light strips is emitted through the interaction between the one-way mirror and the semi-transparent mirror and is finally emitted through the semi-transparent mirror. However, because the LED light strips are installed on the side wall between the one-way mirror and the semi-transparent mirror, the large amount of heat generated by the LED light strips when they are working will be directly dissipated through this side wall. Thus, when the driver operates or touches the automotive display device, the heated side wall will affect the driver's experience. Utility Model Content

[0004] To address the shortcomings of the existing manufacturing technology, the applicant provides an automotive display device with heat dissipation function. By improving the structure of the automotive display device and changing the installation position of the LED lights, the heat dissipation position of the LED lights is adjusted, thereby improving the driver's experience.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A car display device with heat dissipation function includes: a base, an annular support, a display, a PCBA, an LED, and a heat dissipation mechanism. The annular support is mounted on the base, the display is mounted on the annular support, the PCBA is mounted on the base, the LED is mounted on the side of the PCBA away from the base, the light emitted by the LED is emitted through the display, and the heat dissipation mechanism is mounted on the side of the base away from the PCBA. The heat generated by the LED when it is working is dissipated from the side of the base away from the PCBA through the heat dissipation mechanism.

[0007] Therefore, by mounting the LED lights and PCBA together on the base, and providing a heat dissipation mechanism on the base to dissipate the heat generated by the LED lights during operation, this method is simpler in structure and easier to operate compared to the existing method of mounting LED lights on a ring support. It avoids the ring support and improves the driver's experience. In addition, by mounting the LED lights directly on the PCBA, the LED light strip on the side wall of the ring support and the FPC used for connection are eliminated, thereby reducing the overall production and assembly cost of the automotive display device.

[0008] As a further improvement to the above technical solution: the heat dissipation mechanism includes a first heat-conducting part, a heat dissipation hole, and a second heat-conducting part. The first heat-conducting part is installed on the side of the PCBA away from the LED light, the heat dissipation hole is opened on the base relative to the LED light, and the second heat-conducting part is installed on the inner wall of the heat dissipation hole. Thus, the heat generated by the LED light during operation is transferred to the PCBA, and after being conducted by the first and second heat-conducting parts, it is finally dissipated through the heat dissipation hole. The first and second heat-conducting parts can accelerate heat transfer, and the heat dissipation hole, located on the base relative to the LED light, can reduce the heat transfer path, allowing the heat generated by the LED light during operation to be directly dissipated through the heat dissipation hole. This improves the overall heat dissipation effect of the automotive display device.

[0009] As a further improvement to the above technical solution: the display unit includes a semi-transparent lens and a one-way mirror, both of which are mounted on the annular support, with the semi-transparent lens located on the side of the one-way mirror furthest from the base. Thus, the light emitted by the LED lamp, through the interaction of the semi-transparent lens and the one-way mirror, is ultimately emitted through the semi-transparent lens.

[0010] As a further improvement to the above technical solution: there is a gap between the one-way mirror and the annular support. Therefore, the gap between the one-way mirror and the annular support is used for light extraction; if there were no gap between the one-way mirror and the annular support, the light emitted by the LED lamp would not be able to ultimately pass through the semi-transparent lens.

[0011] As a further improvement to the above technical solution: the PCBA has a circular cross-sectional shape; multiple LEDs are provided, and the multiple LEDs are distributed in a ring with equal spacing. Therefore, by using multiple LEDs, different lighting effects can be achieved in the automotive display device.

[0012] As a further improvement to the above technical solution: multiple heat dissipation holes and multiple second heat-conducting parts are provided; the number of heat dissipation holes and the number of second heat-conducting parts are equal to the number of LEDs. Thus, the heat dissipation holes and the second heat-conducting parts correspond one-to-one with the LEDs, so that the heat generated by each LED is directly dissipated through the heat dissipation hole at the bottom of the LED.

[0013] As a further improvement to the above technical solution: the inner wall of the annular support is provided with an installation groove; the outer peripheral surface of the one-way mirror is provided with an installation part, the installation part is placed in the installation groove, and is installed on the side wall of the annular support by a locking member.

[0014] As a further improvement to the above technical solution: the inner wall of the annular support is provided with a slot; the outer peripheral surface of the semi-transparent lens is provided with a buckle, which is placed in the slot so that the semi-transparent lens is connected to the annular support.

[0015] As a further improvement to the above technical solution, the mounting groove and the slot are offset from each other. Therefore, the offset mounting groove and slot ensure that the installation of the one-way mirror and the semi-transparent mirror do not interfere with each other, thus facilitating the installation of both.

[0016] As a further improvement to the above technical solution: a lever is provided on the outer wall of the annular support relative to the slot, the lever being used to move the buckle so that the buckle disengages from the slot. Thus, the interaction between the slot and the buckle facilitates the installation of the semi-transparent lens, and the interaction between the lever and the buckle facilitates the disassembly of the semi-transparent lens.

[0017] The beneficial effects of this utility model are as follows:

[0018] By mounting the LED lights and PCBA together on the base, and providing a heat dissipation mechanism on the base to dissipate the heat generated by the LED lights during operation, this method is simpler in structure and easier to operate compared to the existing method of mounting LED lights on a ring support. It avoids the ring support and improves the driver's experience. In addition, by mounting the LED lights directly on the PCBA, the LED light strip on the side wall of the ring support and the FPC used for connection are eliminated, thereby reducing the overall production and assembly cost of the automotive display device.

[0019] This utility model also has the following advantages:

[0020] 1. The heat generated by the LED lamp during operation is transferred to the PCBA and then dissipated through the first and second heat-conducting parts. The first and second heat-conducting parts can accelerate the heat transfer. The heat dissipation holes are located on the base relative to the LED lamp, which can reduce the heat transfer path and allow the heat generated by the LED lamp during operation to be directly dissipated through the heat dissipation holes. This improves the heat dissipation effect of the entire automotive display device.

[0021] 2. The gap between the one-sided mirror and the annular support part of this utility model is used for light output. If there is no gap between the one-sided mirror and the annular support part, the light emitted by the LED lamp cannot be ultimately emitted through the semi-transparent lens.

[0022] 3. This utility model can achieve different lighting effects for automotive display devices by setting multiple LED lights. Attached Figure Description

[0039] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0040] like Figures 1 to 7 The diagram shows the preferred embodiment of this utility model. The automotive display device with heat dissipation function in this embodiment includes: a base 1, an annular support 2, a display 3, a PCBA 4, and an LED lamp 5. The annular support 2 is mounted on the base 1, the display 3 is mounted on the annular support 2, the PCBA 4 is mounted on the base 1, the LED lamp 5 is mounted on the side of the PCBA 4 away from the base 1, and the light emitted by the LED lamp 5 is emitted through the display 3. The heat dissipation mechanism 6 is mounted on the side of the base 1 away from the PCBA 4, and the heat generated by the LED lamp 5 when it is working is dissipated from the side of the base 1 away from the PCBA 4 through the heat dissipation mechanism 6. Therefore, by mounting the LED light 5 together with the PCBA4 on the base 1, and providing a heat dissipation mechanism 6 on the base 1 to dissipate the heat generated by the LED light 5 during operation, this method is simpler in structure and easier to operate than the existing method of mounting the LED light 5 on the annular support 2. It can avoid the annular support 2 and improve the driver's experience. In addition, the LED light 5 is directly mounted on the PCBA4, eliminating the LED light 5 strip on the side wall of the annular support 2 and the FPC used for connection, thereby reducing the overall production and assembly cost of the automotive display device.

[0041] In other words, since the LED light 5 and PCBA4 are mounted together on the base 1, the heat generated by the LED light 5 is dissipated through the base 1. When the entire automotive display device is in use, the driver will only touch the annular support 2 and the semi-transparent lens 301, and will not touch the base 1. In this way, the annular support 2 and the semi-transparent lens 301 will not generate heat, thus improving the driver's experience. In addition, since the LED light 5 and PCBA4 are mounted together on the base 1, the LED light 5 does not need to be connected to the PCBA4 through the FPC (i.e., the LED light 5 is directly connected to the PCBA4). At the same time, the LED light strip is eliminated, thus reducing the number of accessories required for the entire automotive display device, thereby increasing the production and assembly cost of the entire automotive display device.

[0042] In this embodiment, the heat dissipation mechanism 6 includes: a first heat-conducting part 601, a heat dissipation hole 602, and a second heat-conducting part 603. The first heat-conducting part 601 is installed on the side of PCBA4 away from the LED lamp 5. The heat dissipation hole 602 is opened at the position of the base 1 relative to the LED lamp 5. The second heat-conducting part 603 is installed on the inner wall of the heat dissipation hole 602. Multiple heat dissipation holes 602 and multiple second heat-conducting parts 603 are provided. The number of heat dissipation holes 602 and the number of second heat-conducting parts 603 are equal to the number of LED lamps 5. Therefore, the heat generated by the LED 5 during operation is transferred to the PCBA4, and after being conducted by the first heat-conducting part 601 and the second heat-conducting part 603, it is finally dissipated through the heat dissipation hole 602. The first heat-conducting part 601 and the second heat-conducting part 603 can accelerate the heat transfer. The heat dissipation hole 602 is opened at the position of the base 1 relative to the LED 5, which can reduce the heat transfer path, so that the heat generated by the LED 5 during operation can be directly dissipated through the heat dissipation hole 602. In this way, the heat dissipation effect of the entire automotive display device can be improved. The heat dissipation hole 602 and the second heat-conducting part 603 correspond one-to-one with the LED 5, so that the heat generated by each LED 5 can be directly dissipated through the heat dissipation hole 602 at the bottom of the LED 5.

[0043] For example, the first heat-conducting part 601 uses a heat-dissipating strip, and the second heat-conducting part 603 uses a ring-shaped heat sink made of metal.

[0044] In this embodiment, the display unit 3 includes a semi-transparent mirror 301 and a one-way mirror 302. Both the semi-transparent mirror 301 and the one-way mirror 302 are mounted on the annular support 2, with the semi-transparent mirror 301 located on the side of the one-way mirror 302 away from the base 1. There is a gap between the one-way mirror 302 and the annular support 2. Thus, the light emitted by the LED lamp 5 is emitted through the semi-transparent mirror 301 through the interaction of the semi-transparent mirror 301 and the one-way mirror 302.

[0045] In this embodiment, the PCBA4 has a circular cross-sectional shape; multiple LEDs 5 are arranged in a ring with equal spacing. Thus, by setting multiple LEDs 5, different lighting effects can be achieved for the automotive display device (e.g., multiple LEDs 5 displaying different colors, turning on one LED 5, turning on two LEDs 5 displaying the same color, or turning on multiple LEDs 5 displaying different colors, etc.).

[0046] In this embodiment, the inner wall of the annular support 2 is provided with a mounting groove 201; the outer peripheral surface of the one-way mirror 302 is provided with a mounting part 303, which is placed in the mounting groove 201 and is installed on the side wall of the annular support 2 by a locking member 304; the inner wall of the annular support 2 is provided with a slot 202; the outer peripheral surface of the semi-transparent lens 301 is provided with a buckle 305, which is placed in the slot 202 so that the semi-transparent lens 301 is connected to the annular support 2; the mounting groove 201 and the slot 202 are offset from each other; a lever 203 is provided on the outer wall of the annular support 2 at a position relative to the slot 202, and the lever 203 is used to move the buckle 305 so that the buckle 305 is disengaged from the slot 202. Therefore, the staggered mounting slots 201 and 202 ensure that the installation of the one-way mirror 302 and the semi-transparent mirror 301 do not interfere with each other, thus facilitating the installation of the one-way mirror 302 and the semi-transparent mirror 301. The mutual cooperation between the 202 and the 305 facilitates the installation of the semi-transparent mirror 301, and the mutual cooperation between the lever 203 and the 305 facilitates the disassembly of the semi-transparent mirror 301.

[0047] Specifically, the installation process of the one-way mirror 302 and the semi-transparent mirror 301 is as follows: First, install the one-way mirror 302, then install the semi-transparent mirror 301. Align the mounting part 303 with the mounting groove 201 and tighten the locking part 304. This allows the one-way mirror 302 to be installed. Align the buckle 305 with the slot 202 and apply pressure to the side closer to the one-way mirror 302. This allows the semi-transparent mirror 301 to be installed. The disassembly process of the one-way mirror 302 and the semi-transparent mirror 301 is as follows: First, disassemble the semi-transparent mirror 301, then disassemble the one-way mirror 302. By pressing the lever 203, the buckle 305 is released from the slot 202. This allows the semi-transparent mirror 301 to be disassembled. Loosen the locking part 304. This allows the one-way mirror 302 to be disassembled.

[0048] For example, the locking component 304 uses bolts.

[0049] The working process of this utility model's automotive display device is as follows: First, align the mounting part 303 with the mounting groove 201 and tighten the locking part 304 so that the one-way mirror 302 is installed into the annular support block. Then, apply pressure to the side near the one-way mirror 302, and with the cooperation of the slot 202 and the buckle 305, insert the buckle 305 into the slot 202, thus installing the semi-transparent lens 301 on the annular support part 2. Finally, turn on the LED light 5, and with the cooperation of the semi-transparent lens 301 and the one-way mirror 302, the light emitted by the LED light 5 is emitted through the semi-transparent lens 301 (e.g., light emitted from the LED light 5). Figure 6 As shown in the figure, the heat generated by the LED light 5 when it is working is conducted through the first heat-conducting part 601 and the second heat-conducting part 603 in sequence, and finally dissipated through the heat dissipation hole 602 opened on the base 1.

[0050] In summary, this utility model mounts the LED light 5 and PCBA4 together on the base 1, and provides a heat dissipation mechanism 6 on the base 1 to dissipate the heat generated by the LED light 5 during operation. Compared with the existing mounting method where the LED light 5 is mounted on the annular support 2, this method has a simpler structure, is easier to operate, and avoids the annular support 2, thereby improving the driver's experience. In addition, the LED light 5 is directly mounted on the PCBA4, eliminating the LED light 5 strip on the side wall of the annular support 2 and the FPC used for connection, thus reducing the overall production and assembly cost of the automotive display device.
