Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicle-mounted instruments, and in particular to a vehicle-mounted instrument device and a dual-type vehicle-mounted instrument. Background Art

[0002] With the popularization of automobiles and the development of multimedia, instrument systems and multimedia systems are becoming more and more intelligent. In-vehicle instrument panels that combine central control systems and speedometer systems have appeared on the market. Since the internal environment is affected by the external environment, especially in summer, the internal temperature of the car is relatively high. Therefore, starting the in-vehicle instrument panel under high temperature conditions will affect its operating performance. If the heat dissipation performance of the in-vehicle instrument panel is poor, it may cause frame drops or freeze and restart at the least, and the chip of the in-vehicle instrument panel may be damaged at the worst, making the equipment unable to work normally and increasing the equipment maintenance cost.

[0003] The existing patent CN214795780U discloses a 5G multi-control vehicle-mounted central control all-in-one structure, including a display screen, a front frame, a circuit board and a heat dissipation back cover. The heat dissipation back cover is arranged on the back of the front frame, and the upper and lower surfaces of the circuit board, which serves as the main heat-generating device, are provided with heat dissipation channels. Together with the heat dissipation holes on the heat dissipation back cover, they form an air circulation channel, which is conducive to quickly taking away heat, thereby improving the heat tolerance performance of the vehicle-mounted central control all-in-one.

[0004] However, the heat dissipation rear cover accounts for a large proportion of the thickness of the above device, thereby making the overall structure of the above device thicker and heavier, which is not conducive to its convenient disassembly and assembly. Utility Model Content

[0036] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0037] See also Figure 1 、 Figure 4 and Figure 6 , which is a vehicle-mounted instrument device 10 according to an embodiment of the present invention, including a protective cover 100, an instrument display assembly 200, a central control display assembly 300, thermal paste 400, a thermal cover 500 and screws (not shown).

[0038] like Figures 1 to 3As shown, the protective cover 100 has a speedometer display area 101 and a central control display area 102. The protective cover 100 is provided with a plurality of screw posts 110, and the screw posts 110 are provided with screw holes 110a.

[0039] like Figure 4 and Figure 5 As shown, the instrument display assembly 200 includes a speedometer display screen 210 and a speedometer control board 220, the display control end of the speedometer control board 220 is electrically connected to the speedometer display screen 210, the display end of the speedometer display screen 210 is arranged toward the speedometer display area 101, and the speedometer display screen 210 is provided with a first through hole 210a; the central control display assembly 300 includes a central control display screen 310 and a central control board 320, the display control end of the central control board 320 is electrically connected to the central control display screen 310, the communication end of the central control board 320 is electrically connected to the communication receiving end of the speedometer control board 220, the display end of the central control display screen 310 is arranged toward the central control display area 102, and the central control display screen 310 is provided with a second through hole 310a; the thermal paste 400 is respectively arranged in the heat dissipation area of ​​the speedometer control board 220 and the heat dissipation area of ​​the central control board 320, that is, the speedometer control board 2 20 has a speedometer central processor, and the central control board 320 has a central control processor. Both will generate heat when working. At this time, thermal paste 400 needs to be covered on the speedometer central processor and the central control processor to facilitate heat dissipation; the thermal cover 500 is connected to the protective surface cover 100, and the thermal paste 400 abuts against the thermal cover 500; the screw includes a first screw and a second screw, the first screw is sequentially passed through the first through hole 210a and the screw hole 110a and is screwed to the protective surface cover 100, the top of the first screw abuts against the speedometer display screen 210, so that the speedometer display screen 210 is connected to the speedometer control board 220 through the first screw, the second screw is sequentially passed through the second through hole 310a and the screw hole 110a and is screwed to the protective surface cover 100, the top of the second screw abuts against the central control display screen 310, so that the central control display screen 310 is connected to the central control control board 320 through the second screw.

[0040] In this embodiment, when the vehicle-mounted instrument device 10 is working, the speedometer control board 220 and the central control board 320 generate heat. Since the thermal paste 400 is in contact with the thermal cover 500, the heat generated by the speedometer control board 220 and the central control board 320 is transferred to the thermal cover 500 through the thermal paste 400, thereby achieving a better heat dissipation effect. It can be understood that when the vehicle-mounted instrument is working, the speedometer display screen 210 and the central control display screen 310 display the corresponding information normally. At the same time, the speedometer control board 220 and the central control board 320 generate heat when working. At this time, the thermal paste 400 transfers the heat to the thermal cover 500, so that the heat is dissipated on the thermal cover 500, and thus the device has a better heat dissipation performance. At the same time, compared with the prior art, the above-mentioned vehicle-mounted instrument device 10 only needs to loosen the first screw or the second screw and remove it when replacing the instrument display component 200 or the central control display component 300, and the replacement operation can be performed. The thickness of the thermal conductive cover 500 accounts for a relatively low proportion in the overall thickness of the vehicle-mounted instrument device 10, so that the overall structure of the device is lighter and the disassembly and assembly are more convenient.

[0041] In this embodiment, thermal paste 400 is thermal silicone grease. As will be appreciated, thermal silicone grease has excellent thermal conductivity and high thermal conductivity. It is an insulating silicone material that can be used to dissipate heat from electronic components such as electron tubes and CPUs, ensuring the proper operation of the entire device. It is also suitable for the vehicle-mounted instrument device 10 of this embodiment. Of course, thermal paste 400 can also be a thermally conductive sheet, thermally conductive silicone, thermally conductive gel, etc.

[0042] like Figure 4 As shown, in one embodiment, the instrument display assembly 200 further includes an instrument speaker 230, and the sound signal enable terminal of the speedometer control board 220 is electrically connected to the instrument speaker 230. It will be understood that the speedometer control board 220 is also used to connect to the controllers of various components of the vehicle, such as the vehicle speed sensor, the headlight sensor, the battery level sensor, etc., so that the speedometer control board 220 can read the status information of various components of the vehicle. When the acquired status information changes, such as when the lights are abnormal, the turn signal is manually turned on, or the drive motor is started, the speedometer control board 220 outputs a corresponding signal and emits a prompt sound to inform the user. Furthermore, the provision of the instrument speaker 230 makes the instrument display assembly 200 more interactive.

[0043] like Figure 1 and Figure 6As shown, in one embodiment, the vehicle-mounted instrument device 10 further includes a mounting plate 600, which is connected to the heat-conducting cover 500. It is understood that one end of the mounting plate 600 is connected to the heat-conducting cover 500, and the other end of the mounting plate 600 is used to connect to the control platform in front of the driver. When the vehicle-mounted instrument device 10 is assembled, it is installed in the mounting slot in the control console to fix the vehicle-mounted instrument device 10. Specifically, the vehicle-mounted instrument device 10 is fixed to the mounting slot in the front control console by screws. Furthermore, the mounting plate 600 includes a first mounting plate 610 and a second mounting plate 620. The first mounting plate 610 is installed on the left side of the heat-conducting cover 500, and the second mounting plate 620 is installed on the right side of the heat-conducting cover 500. That is, the first mounting plate 610 and the second mounting plate 620 are respectively arranged on the corresponding sides of the heat-conducting cover 500, so that the vehicle-mounted instrument device 10 has better balance after installation.

[0044] In this embodiment, the first mounting piece 610 and the second mounting piece 620 are disposed on the same horizontal plane. It is understood that the horizontal line of the first mounting piece 610 coincides with the horizontal line of the second mounting piece 620, and the vertical line of the first mounting piece 610 is parallel to the vertical line of the second mounting piece 620. This ensures that the vehicle-mounted instrument device 10 does not form a certain angle with the horizontal plane after installation, that is, the vehicle-mounted instrument device 10 is not tilted on the front console.

[0045] like Figure 4 and Figure 6 As shown, in one embodiment, the central control display assembly 300 further includes a power supply socket 330, which is electrically connected to the power supply end of the central control panel 320, and the heat conductive cover 500 is provided with a power supply avoidance hole 501, and the power supply socket 330 is passed through the power supply avoidance hole 501. It can be understood that the power supply socket 330 is used to connect to the power supply source, and the power supply socket 330 is passed through the power supply avoidance hole 501, so that the power supply avoidance hole 501 plays a role of avoidance, avoiding the power supply socket 330 from being attached. When the power supply socket 330 is connected by wiring, the central control panel 320 is powered, and then the central control panel 320 communicates normally with the speedometer control panel 220, and the speedometer display screen 210 and the central control display screen 310 work normally.

[0046] like Figure 4 As shown, in one embodiment, the central control display assembly 300 further includes a power amplifier chip 340, which is electrically connected to the input signal amplification terminal of the central control board 320. It can be understood that the power amplifier chip 340 is used to amplify the weak electrical signal from the signal source, i.e., the input signal, to drive the speaker to normally produce sound, thereby allowing the user to generate feedback sound or play multimedia when operating the central control display screen 310.

[0047] like Figure 1As shown, in one embodiment, the protective cover 100 further has a key touch area 103, as shown in the dotted frame. The key touch area 103 is electrically connected to the key signal enable receiving terminal of the central control panel 320 to control the display status of the central control panel 320. It can be understood that the key touch area 103 includes multiple touch screen buttons. The user can click the touch screen buttons to cause the central control panel 320 to receive the button signal and output the corresponding data, and display the corresponding result on the central control display screen 310. For example, if the user needs to adjust the volume, they can click Volume + or Volume -, causing the central control panel 320 to receive the volume adjustment signal, output the corresponding data, and display the volume change on the central control display screen 310, and so on.

[0048] The present disclosure further provides a dual-type vehicle-mounted instrument, comprising the vehicle-mounted instrument device 10 according to any one of the above embodiments.

[0049] Compared with the prior art, the present disclosure has at least the following advantages:

[0050] When the vehicle-mounted instrument device 10 is working, the speedometer control board 220 and the central control board 320 generate heat. Since the thermal paste 400 is in contact with the thermal cover 500, the heat generated by the speedometer control board 220 and the central control board 320 is transferred to the thermal cover 500 through the thermal paste 400 to achieve a better heat dissipation effect. At the same time, compared with the prior art, the above-mentioned vehicle-mounted instrument device 10 only needs to loosen the first screw or the second screw and remove it when replacing the instrument display assembly 200 or the central control display assembly 300, and the replacement operation can be carried out. In addition, the thickness of the thermal cover 500 accounts for a relatively low proportion in the overall thickness of the vehicle-mounted instrument device 10, so that the overall structure of the device is lighter and the disassembly and assembly are more convenient.

[0051] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the disclosed patent shall be determined by the appended claims.
