Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to an in-vehicle triple-screen display device and a vehicle. Background Technology

[0002] With the development of automotive intelligence, triple-screen displays have become standard equipment in some models. These displays typically include a main control screen, a central control screen, and a passenger-side screen. This multi-screen system not only achieves zoned display of driving information, navigation and entertainment, and passenger interaction, but also significantly improves the human-machine interaction experience. However, triple-screen displays pose significant challenges to heat dissipation performance and multi-tasking capabilities.

[0003] Currently, most in-vehicle triple-screen displays on the market use a method where each display is independently connected to a temperature sensor and controlled separately. This design results in high hardware costs. Furthermore, when the temperature of the passenger-side circuit board exceeds a threshold, the passenger-side display turns off, and when the temperature of the central control circuit board exceeds a threshold, the central control display turns off. The central control display mainly displays key driving information, while the passenger-side display is mostly for entertainment purposes. Turning off the central control display will affect driving safety and user experience. Utility Model Content

[0004] The purpose of this invention is to solve the problem of high hardware costs associated with in-vehicle triple-screen displays. This invention provides an in-vehicle triple-screen display device and vehicle, which can effectively reduce hardware costs and improve driving safety and user experience.

[0005] To address the aforementioned technical problems, this utility model discloses a vehicle-mounted triple-screen display device, an instrument panel bracket including a front, a back, a first window, and a second window, with the first and second windows spaced apart; a passenger-side display screen fixed to the first window and positioned on the same side as the front; a central control display screen fixed to the second window and positioned on the same side as the front; the back panel includes a passenger-side circuit board and a central control circuit board, with the passenger-side circuit board facing the passenger-side display screen and the central control circuit board facing the central control display screen; the back panel also includes a first circuit switch and a second circuit switch, with the passenger-side circuit board and the passenger-side display screen electrically connected via the first circuit switch, and the central control circuit board and the central control display screen electrically connected via the second circuit switch. The circuit switch is electrically connected; the passenger-side circuit board is electrically connected to the central control circuit board; the central control circuit board is equipped with a central control circuit board temperature sensor and a passenger-side circuit board temperature sensor, the central control circuit board temperature sensor is used to detect the temperature of the central control circuit board, and the passenger-side circuit board temperature sensor is used to detect the temperature of the passenger-side circuit board; the vehicle-mounted triple-screen display device includes a first state and a second state; in the first state, if either the temperature of the central control circuit board or the temperature of the passenger-side circuit board is higher than a threshold, the first circuit switch is in an open state and the second circuit switch is in a closed state; in the second state, if both the temperature of the central control circuit board and the temperature of the passenger-side circuit board are higher than the threshold, both the first circuit switch and the second circuit switch are in an open state.

[0006] By adopting the above technical solution, the temperature sensors of the central control circuit board and the passenger side circuit board are integrated on the central control circuit board. Temperature detection of both the central control circuit board and the passenger side circuit board is achieved uniformly through the central control circuit board.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Currently, most in-vehicle triple-screen displays on the market use a method where each display is independently connected to a temperature sensor and controlled separately. This design results in high hardware costs. Furthermore, when the temperature of the passenger-side circuit board exceeds a threshold, the passenger-side display turns off, and when the temperature of the central control circuit board exceeds a threshold, the central control display turns off. The central control display mainly displays key driving information, while the passenger-side display is mostly for entertainment purposes. Turning off the central control display will affect driving safety and user experience.

[0031] Therefore, this application provides a vehicle-mounted triple-screen display device for use in a vehicle. The dashboard bracket is fixed to the vehicle frame, and the passenger-side circuit board temperature sensor and the central control circuit board sensor are integrated on the central control circuit board. When the temperature of the central control circuit board or the passenger-side circuit board is higher than a threshold, the passenger-side display screen is in a closed state, and the central control display screen is in a closed state, which can effectively improve driving safety and user experience.

[0032] Specifically, refer to Figure 1The vehicle-mounted triple-screen display device 100 of this application embodiment includes an instrument panel bracket 200, a passenger-side display screen 300, a central control display screen 400, and a main control display screen 500. The instrument panel bracket 200 includes a front 210, a back 220, a first window 230, a second window 240, and a third window 250. The first window 230, the second window 240, and the third window 250 are arranged in sequence at intervals. The passenger-side display screen 300 is fixed to the first window 230 and is arranged on the same side as the front 210. The central control display screen 400 is fixed to the second window 240 and is arranged on the same side as the front 210. The main control display screen 500 is fixed to the third window 250 and is arranged on the same side as the front 210.

[0033] Specifically, the first window 230, the second window 240, and the third window 250 are arranged alternately from right to left as shown in the figure, and are used to fix the passenger-side display screen 300, the central control display screen 400, and the main control display screen 500, respectively.

[0034] In some possible embodiments, the first window 230, the second window 240 and the third window 250 can be arranged alternately from left to right, that is, the passenger display screen 300, the central control display screen 400 and the main control display screen 500 can be arranged from left to right.

[0035] In this embodiment, the display area of ​​the main control display screen 500 is smaller than that of the central control display screen 400, and the display area of ​​the central control display screen 400 is equal to that of the passenger-side display screen 300. However, those skilled in the art will understand that in other embodiments, the display area of ​​the main control display screen 500 may be larger than that of the central control display screen 400, and the display area of ​​the central control display screen 400 may not be equal to that of the passenger-side display screen 300. This application does not impose any limitations on this.

[0036] refer to Figure 2 The back 220 is equipped with a passenger side circuit board 221, a central control circuit board 222 and a main control circuit board 223. The passenger side circuit board 221 is opposite to the passenger side display screen 300, the central control circuit board 222 is opposite to the central control display screen 400, and the main control circuit board 223 is opposite to the main control display screen 500.

[0037] For example, the passenger-side circuit board 221, the central control circuit board 222, and the main control circuit board 223 are all printed circuit boards. However, those skilled in the art will understand that in other embodiments, the passenger-side circuit board 221, the central control circuit board 222, and the main control circuit board 223 can be other types of circuit boards, such as metal core circuit boards, aluminum substrates, etc., and this application does not limit them.

[0038] Further, refer to Figure 2 and Figure 3The back 220 is also equipped with a first circuit switch 224, a second circuit switch 225 and a third circuit switch 226. The passenger side circuit board 221 is electrically connected to the passenger side display screen 300 via the first circuit switch 224. The central control circuit board 222 is electrically connected to the central control display screen 400 via the second circuit switch 225. The main control circuit board 223 is electrically connected to the main control display screen 500 via the third circuit switch 226. The first circuit switch 224 is integrated on the passenger side circuit board 221, the second circuit switch 225 is integrated on the central control circuit board 222, and the third circuit switch 226 is integrated on the main control circuit board 223.

[0039] Specifically, the first circuit switch 224 controls the switch of the passenger-side display screen 300, the second circuit switch 225 controls the switch of the central control display screen 400, and the third circuit switch 226 controls the switch of the main control display screen 500.

[0040] Further, refer to Figure 2 The passenger-side circuit board 221 is electrically connected to the central control circuit board 222. The passenger-side circuit board 221 and the central control circuit board 222 are connected through a first flexible circuit board 227. The central control circuit board 222 is equipped with a central control circuit board temperature sensor 2221 and a passenger-side circuit board temperature sensor 2222. The central control circuit board temperature sensor 2221 is used to detect the temperature of the central control circuit board 222, and the passenger-side circuit board temperature sensor 2222 is used to detect the temperature of the passenger-side circuit board 221. The vehicle-mounted triple-screen display device 100 includes a first state and a second state. In the first state, when either the temperature of the central control circuit board 222 or the temperature of the passenger-side circuit board 221 is higher than a threshold, the second circuit switch 225 is in the open state, and the passenger-side display screen 300 is turned off. In the second state, when both the temperature of the central control circuit board 222 and the temperature of the passenger-side circuit board 221 are higher than the threshold, both the first circuit switch 224 and the second circuit switch 225 are in the open state, and both the passenger-side display screen 300 and the central control display screen 400 are turned off.

[0041] For example, the passenger side circuit board 221 and the central control circuit board 222 are electrically connected via a first flexible circuit board 227. However, those skilled in the art will understand that in other embodiments, the passenger side circuit board 221 and the central control circuit board 222 can be electrically connected in other ways, such as rigid connectors, wireless connections, etc., and this application does not limit this.

[0042] It should be noted that by integrating the central control circuit board temperature sensor 2221 and the passenger-side circuit board temperature sensor 2222 onto the central control circuit board 222, the temperature detection of both the central control circuit board 222 and the passenger-side circuit board 221 can be uniformly achieved through the central control circuit board 222. Compared to integrating the central control circuit board temperature sensor 2221 and the passenger-side circuit board temperature sensor 2222 onto the central control circuit board 222 and the passenger-side circuit board 221 respectively, this solution reduces the related circuit design for temperature detection on the passenger-side circuit board 221, thereby effectively reducing hardware costs. Furthermore, the central control display screen 400 mainly carries the function of displaying key driving information, while the passenger-side display screen 300 is mainly for entertainment purposes, and the passenger-side display screen 300 has higher heat generation and energy consumption. When the temperature of either the passenger-side circuit board 221 or the central control circuit board 222 exceeds the threshold, the passenger-side display screen 300 is turned off, which can effectively reduce the system temperature, while the central control display screen 400 continues to operate. Compared to directly turning off the central control display screen 400 when its temperature exceeds the threshold, this can effectively improve driving safety and user experience.

[0043] Specifically, the circuit board collects temperature data (in electrical signal form) transmitted by the circuit board temperature sensor. Based on the temperature signal value, it outputs an on / off signal to the circuit switch. That is, in the first state, when the temperature data transmitted by the passenger side circuit board temperature sensor 2222 collected by the central control circuit board 222 is higher than the threshold, or when the temperature data output by the central control circuit board temperature sensor 2221 collected by the central control circuit board 222 is higher than the threshold, the central control circuit board 222 outputs an off signal to the first circuit switch 224, and the passenger side display screen 300 is turned off. In the second state, when the temperature data transmitted by both the passenger side circuit board temperature sensor 2222 and the central control circuit board temperature sensor 2221 collected by the central control circuit board 222 are higher than the threshold, the central control circuit board 222 simultaneously outputs an off signal to both the first circuit switch 224 and the second circuit switch 225, and both the passenger side display screen 300 and the central control display screen 400 are turned off.

[0044] For example, the function of a circuit switch can be implemented by a logic circuit connecting the collector of one transistor to the emitter of another transistor. This can be viewed as a simple AND gate circuit. When the bases of both transistors are connected to a high level, the circuit is on; if either is not connected to a high level, the circuit is off. In other words, configuring the appropriate number and specifications of transistors can realize the function of the logic circuit, thereby enabling the logic control module to output the corresponding target control signal according to the logical relationship based on whether the corresponding reference electrical signal is received. Specifically, when the temperature data collected by the central control circuit board 222 from both the central control circuit board temperature sensor 2221 and the passenger side circuit board temperature sensor 2222 are below the threshold, the bases of the two transistors of the first circuit switch 224 and the second circuit switch 225 are both connected to a high level, the first circuit switch 224 and the second circuit switch 225 are turned on, and the passenger side display screen 300 and the central control circuit display screen 400 are lit up; when the temperature data collected by the central control circuit board 222 from either the central control circuit board temperature sensor 2221 or the passenger side circuit board temperature sensor 2222 are below the threshold, one of the two transistors of the first circuit switch 224 is not connected to a high level, and both transistors of the second circuit switch 225 are connected to a high level, the circuit of the first circuit switch 224 is not turned on, the circuit of the second circuit switch 225 is turned on, the passenger side display screen 300 is turned off, and the central control circuit display screen 400 is lit up.

[0045] For example, the threshold ranges from 75°C to 90°C, such as 75°C, 80°C, 85°C, and 90°C.

[0046] Further, refer to Figure 2 The main control circuit board 223 and the central control circuit board 222 are connected through the second flexible circuit board 228.

[0047] Specifically, the main control circuit board 223 and the intermediate control circuit board 222 are connected through the second flexible circuit board 228, which reduces the design of temperature detection circuits on the main control circuit board 223, thereby effectively reducing hardware costs.

[0048] Further, refer to Figure 2 The passenger side circuit board 221 is also equipped with a first passenger side screen temperature sensor 2211 and a second passenger side screen temperature sensor 2212; the central control circuit board 222 is also equipped with a central control screen temperature sensor 2223 and an ambient temperature sensor 2224; the main control circuit board 223 is also equipped with a main control screen temperature sensor 2231.

[0049] Specifically, combining the aforementioned passenger-side circuit board temperature sensor 2222 and central control circuit board temperature sensor 2221, the back panel 220 has a total of 7 temperature detection sensors. For the passenger-side display screen 300, when the passenger-side circuit board 221 detects that the temperature output by the first passenger-side screen temperature sensor 2211 is higher than a threshold, the passenger-side circuit board 221 outputs a disconnect signal to the first circuit switch 224, and the passenger-side display screen 300 turns off; when the passenger-side circuit board 221 detects that the temperature output by the second passenger-side screen temperature sensor 2212 is higher than a threshold, the passenger-side circuit board 221 outputs a disconnect signal to the first circuit switch 224, and the passenger-side display screen 300 turns off; for the central control display screen 400... When the central control circuit board 222 detects that the temperature output by the central control screen temperature sensor 2223 is higher than the threshold, the central control circuit board 222 outputs a disconnect signal to the second circuit switch 225, and the central control display screen 400 is turned off; when the central control circuit board 222 detects that the temperature output by the ambient temperature sensor 2224 is higher than the threshold, the central control circuit board 222 outputs a disconnect signal to the second circuit switch 225, and the central control display screen 400 is turned off; for the main control display screen 500, when the main control circuit board 223 detects that the temperature output by the main control screen temperature sensor 2231 is higher than the threshold, the main control circuit board 223 outputs a disconnect signal to the third circuit switch 226, and the main control display screen 500 is turned off.

[0050] Further, refer to Figure 2 and Figure 4 The fan 600 is fixed to the back 220. The fan 600 also includes a ventilation pipe 610. The fan 600 has an opening on its side. One end of the ventilation pipe 610 is connected to the opening, and the other end of the ventilation pipe 610 is connected to the central control circuit board 222.

[0051] Specifically, the airflow generated by the fan 600 is directly guided to the central control circuit board 222 through the ventilation pipe 610, which can directly cool the central control circuit board 222 and effectively improve the cooling efficiency.

[0052] For example, when the temperature data output by the temperature sensor 2221 of the central control circuit board 222 is higher than the threshold, the central control circuit board 222 outputs a disconnect signal to the first circuit switch 224, the passenger display screen 300 is turned off, and the fan 600 is turned on to cool the central control circuit board 222.

[0053] In some possible embodiments, the fan 600 is further provided with a second passage and a third passage. One end of the second passage is connected to the fan 600 and the other end is connected to the main control circuit board 223 for cooling the main control circuit board 223. One end of the third passage is connected to the fan 600 and the other end is connected to the passenger side circuit board 221 for cooling the passenger side circuit board 221.

[0054] In this embodiment, the fan 600 is disposed between the passenger-side circuit board 221 and the central control circuit board 222. However, those skilled in the art will understand that in other embodiments, the fan 600 may be disposed in other locations, such as between the central control circuit board 222 and the main control circuit board 223, and this application does not impose any restrictions on this.

[0055] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
