Technical Field
[0001] This disclosure relates to the technical field of engineering vehicle-mounted equipment, and in particular to a screen communication structure and vehicle-mounted display device for engineering vehicles. Background Technology
[0002] In unstructured work environments such as mines and construction sites, engineering vehicles need to travel for extended periods on unpaved roads riddled with gravel and potholes. The resulting severe bumps and vibrations pose a significant challenge to the reliability of in-vehicle screens. Therefore, please refer to [link / reference needed]. Figure 1 To enhance the reliability of screen installation on engineering vehicles, the screen is usually encapsulated and fixed with a metal structure. However, after the screen is encapsulated and fixed with a metal structure, the audio signal received by the screen will be attenuated by the shielding effect of the metal shell, which will affect the normal use of the screen. Utility Model Content

[0009] The outer casing includes a glass top cover, a plastic middle support plate, and a plastic bottom shell stacked from top to bottom; a metal vibration-damping shell is fixedly covered on the back of the display screen, the display screen is disposed between the glass top cover and the plastic middle support plate, and the metal vibration-damping shell is fixedly connected to the plastic middle support plate; a portion of the plastic middle support plate extends beyond the edge of the metal vibration-damping shell and forms an extended mounting portion; a communication configuration cavity is formed between the extended mounting portion and the plastic bottom shell, and a sound receiving hole is opened on the extended mounting portion; a microphone is fixedly disposed at the sound receiving hole, and a communication antenna is fixedly disposed in the communication configuration cavity, and the microphone is communicatively connected to the display screen through the communication antenna.
[0010] In some embodiments, the number of communication antennas is two, and each communication antenna is fixedly connected to one end of the extension mounting portion; there is an anti-interference spacing between the two communication antennas.
[0011] In some embodiments, of the two communication antennas, one is a Bluetooth antenna and the other is a WiFi antenna.
[0012] In some embodiments, the number of microphones is two, and each microphone is communicatively connected to the display screen via a corresponding communication antenna.
[0013] In some embodiments, the communication antenna is a Bluetooth antenna or a WiFi antenna.
[0014] In some embodiments, a portion of the glass cover plate extends above the extended mounting portion and forms a covering portion; the covering portion has a through hole, which is coaxially opposite to the sound receiving hole.
[0015] In some embodiments, the metal anti-vibration shell is provided with a plurality of positioning seats, and the plastic middle plate is formed with a plurality of alignment holes; each positioning seat is matched with a corresponding alignment hole and is locked to the plastic middle plate.

[0019] Compared with the prior art, this disclosure has at least the following advantages:
[0020] The aforementioned communication structure for engineering vehicles utilizes a metal vibration-damping shell on the back of the display screen. After the display screen is positioned between the glass top cover and the plastic support plate, a fixed connection is formed between the metal vibration-damping shell and the plastic support plate. This reduces the amplitude of vibrations caused by the bumps and knocks of the engineering vehicle. Simultaneously, the metal vibration-damping shell helps maintain the screen's shape, minimizing the impact of vibrations. Furthermore, because the plastic support plate extends beyond the edge of the metal vibration-damping shell, it forms an extended mounting portion on the outside of the shell. By fixing a microphone to the microphone's receiving port on the plastic support plate, external sounds can be received through the port. The communication antenna is fixed within the communication cavity between the extended mounting portion of the plastic support plate and the lower plastic shell, reducing the signal shielding of the communication antenna compared to the metal structure. Finally, the microphone is connected to the display screen via the communication antenna, allowing for faster reception and amplification of the microphone signal before transmission to the display screen, thus improving its performance.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0035] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0036] Please see Figure 1 and Figure 2An embodiment of a screen communication structure for an engineering vehicle includes a housing, a display screen 200, a communication antenna 300, and a microphone 400. The housing is used for fixed installation on the center console of the engineering vehicle. The display screen 200 is fixedly installed within the housing. The housing includes a glass top cover 110, a plastic middle support plate 120, and a plastic bottom shell 130 stacked from top to bottom. A metal anti-vibration shell (not shown) is fixedly covered on the back of the display screen 200. The display screen 200 is disposed between the glass top cover 110 and the plastic middle support plate 120. A metal vibration-damping shell is fixedly connected to a plastic middle support plate 120; a portion of the plastic middle support plate 120 extends beyond the edge of the metal vibration-damping shell, forming an extended mounting portion 1210; a communication configuration cavity 1301 is formed between the extended mounting portion 1210 and the plastic lower bottom shell 130, and a sound receiving hole 1201 is provided on the extended mounting portion 1210; a microphone 400 is fixedly disposed at the sound receiving hole 1201, and a communication antenna 300 is fixedly disposed within the communication configuration cavity 1301, and the microphone 400 is communicatively connected to the display screen 200 through the communication antenna 300. The principle of the microphone 400 being communicatively connected to the display screen 200 through the communication antenna 300 is existing technology and will not be described in detail here.
[0037] It is understandable that, since the back of the display screen 200 is covered with a metal vibration-damping shell, after the display screen 200 is placed between the glass top cover plate 110 and the plastic middle support plate 120, the display screen 200 can form a fixed connection structure with the plastic middle support plate 120 through the metal vibration-damping shell, thereby reducing the amplitude of the vibration of the display screen 200 caused by the bumps and vibrations of the engineering vehicle. At the same time, the display screen 200 can maintain its shape through the metal vibration-damping shell to reduce the impact of vibration. Furthermore, since part of the plastic middle support plate 120 extends beyond the edge of the metal vibration-damping shell, the plastic middle support plate 120 can form an extended mounting part 1210 on the outside of the metal vibration-damping shell. Subsequently, by fixing the microphone 400 to the sound receiving hole 1201 of the plastic middle plate 120, external sounds can be received by the microphone 400 through the sound receiving hole 1201. Furthermore, by fixing the communication antenna 300 within the communication configuration cavity 1301 between the extended mounting portion 1210 of the plastic middle plate 120 and the plastic lower shell 130, the signal shielding of the communication antenna 300 by the original metal structure can be reduced through the plastic structure. Finally, the microphone 400 is communicatively connected to the display screen 200 via the communication antenna 300. This allows the communication antenna 300 to receive and amplify the signal from the microphone 400 more quickly, and then transmit the amplified signal to the display screen 200, thereby improving the performance of the display screen 200.
[0038] Please see Figure 3In some embodiments, there are two communication antennas 300, each fixedly connected to one end of the extension mounting portion 1210; the two communication antennas 300 are spaced apart to reduce interference. It can be understood that because each communication antenna 300 is fixedly connected to one end of the extension mounting portion 1210, the microphone 400 can simultaneously communicate with the display screen 200 through both communication antennas 300. Furthermore, the anti-interference space between the two communication antennas 300 reduces signal interference between them, thereby further improving the display screen 200's ability to receive audio signals.
[0039] Please see Figure 3 In some embodiments, a power switch assembly 600 is provided between the two communication antennas 300, the power switch assembly 600 being used to turn the power of the display screen 200 on or off.
[0040] Please see Figure 3 In this embodiment, one of the two communication antennas 300 is a Bluetooth antenna, and the other is a WiFi antenna. It can be understood that since the microphone 400 is connected to the display screen 200 via both Bluetooth and WiFi antennas, the microphone 400 is compatible with both Bluetooth and WiFi data transmission methods, ultimately improving the wireless connection experience of the aforementioned engineering vehicle screen communication structure.
[0041] Please see Figure 3 In some embodiments, there are two microphones 400, each of which is communicatively connected to the display screen 200 via a corresponding communication antenna 300. It can be understood that because each microphone 400 is communicatively connected to the display screen 200 via a corresponding communication antenna 300, each microphone 400 can independently transmit data to the display screen 200 via its corresponding communication antenna 300, ensuring data accuracy.
[0042] In some embodiments, the communication antenna 300 is a Bluetooth antenna or a WiFi antenna. It is understood that when the communication antenna 300 is a Bluetooth antenna, the microphone 400 can transmit data to the display screen 200 via Bluetooth. Alternatively, when the communication antenna 300 is a WiFi antenna, the microphone 400 can transmit data to the display screen 200 via WiFi.
[0043] Please see Figure 1 and Figure 2In some embodiments, a portion of the glass top cover 110 extends above the extension mounting portion 1210, forming a cover portion 1110; a through hole 1101 is provided on the cover portion 1110, and the through hole 1101 is coaxially opposite to the microphone hole 1201. It can be understood that since the cover portion 1110 is located above the extension mounting portion 1210, it can provide protection for the extension mounting portion 1210, and the through hole 1101 on the cover portion 1110, coaxially opposite to the microphone hole 1201, can ensure that the microphone 400 can effectively collect sound through the microphone hole 1201.
[0044] Please see Figure 2 and Figure 3 In some embodiments, the metal vibration-damping shell 210 has a plurality of positioning seats 2110 protruding from it, and the plastic middle support plate 120 has a plurality of alignment holes 1302 formed thereon; each positioning seat 2110 is fitted with a corresponding alignment hole 1302 and is locked to the plastic middle support plate 120. It can be understood that since each positioning seat 2110 formed on the plastic middle support plate 120 is fitted with a corresponding alignment hole 1302 and is locked to the plastic middle support plate 120, a tight connection structure can be formed between the metal vibration-damping shell 210 and the plastic middle support plate 120, so as to reduce the amplitude of vibration of the display screen 200 caused by the bumps of the engineering vehicle.
[0045] Please see Figure 2 and Figure 3 In some embodiments, the plastic middle support plate 120 is provided with a plurality of locking screws (not shown), each locking screw passing through a corresponding alignment hole 1302 and threaded into a screw hole on a corresponding positioning seat 2110. It can be understood that by having each locking screw on the plastic middle support plate 120 pass through the corresponding alignment hole 1302 and threaded into the screw hole on the corresponding positioning seat 2110, the connection strength between the metal vibration-damping shell 210 and the plastic middle support plate 120 can be flexibly adjusted by turning the locking screws.
[0046] Please see Figure 1 and Figure 3 In some embodiments, the screen communication structure for engineering vehicles also includes a touchscreen 500, which is disposed between the glass cover plate 110 and the display screen 200. The touchscreen 500 is attached to the glass cover plate 110 and electrically connected to the mainboard of the display screen 200. It can be understood that by disposing the touchscreen 500 between the glass cover plate 110 and the display screen 200, and by attaching the touchscreen 500 to the glass cover plate 110, it can sense the pressure applied to the glass cover plate 110 and convert the pressure into an electrical signal to the mainboard of the display screen 200, thereby achieving touch control of the display screen 200. The touch control principle is prior art and will not be elaborated upon here.
[0047] Please see Figures 1 to 3 This disclosure also provides an in-vehicle display device, including the engineering vehicle screen communication structure of any of the above embodiments. It can be understood that by applying the engineering vehicle screen communication structure of this disclosure to an in-vehicle display device, since the back of the display screen 200 is covered with a metal vibration-damping shell 210, after the display screen 200 is disposed between the glass top cover plate 110 and the plastic middle support plate 120, the display screen 200 can form a fixed connection structure between the metal vibration-damping shell 210 and the plastic middle support plate 120, thereby reducing the amplitude of the vibration of the display screen 200 caused by the bumps of the engineering vehicle. Simultaneously, the display screen 200 can maintain its shape through the metal vibration-damping shell 210 to reduce the impact of vibration. Furthermore, since a portion of the plastic middle support plate 120 extends beyond the edge of the metal vibration-damping shell 210, the plastic middle support plate 120 can form an extended mounting portion 1210 on the outside of the metal vibration-damping shell 210. Subsequently, by fixing the microphone 400 to the sound receiving hole 1201 of the plastic middle plate 120, external sounds can be received by the microphone 400 through the sound receiving hole 1201. Furthermore, by fixing the communication antenna 300 within the communication configuration cavity 1301 between the extended mounting portion 1210 of the plastic middle plate 120 and the plastic lower shell 130, the signal shielding of the communication antenna 300 by the original metal structure can be reduced through the plastic structure. Finally, the microphone 400 is communicatively connected to the display screen 200 via the communication antenna 300. This allows the communication antenna 300 to receive and amplify the signal from the microphone 400 more quickly, and then transmit the amplified signal to the display screen 200, thereby improving the performance of the display screen 200.
[0048] Compared with the prior art, this disclosure has at least the following advantages:
[0049] In the aforementioned communication structure for engineering vehicles, since the back of the display screen 200 is covered with a metal vibration-damping shell 210, after the display screen 200 is positioned between the glass top cover plate 110 and the plastic middle support plate 120, the display screen 200 can form a fixed connection structure with the metal vibration-damping shell 210 and the plastic middle support plate 120. This reduces the amplitude of the display screen 200's vibration due to the bumps and knocks of the engineering vehicle. At the same time, the display screen 200 can maintain its shape through the metal vibration-damping shell 210 to reduce the impact of vibration. Furthermore, since a portion of the plastic middle support plate 120 extends beyond the edge of the metal vibration-damping shell 210, the plastic middle support plate 120 can form an extended mounting portion 1210 on the outside of the metal vibration-damping shell 210. Subsequently, by fixing the microphone 400 to the sound receiving hole 1201 of the plastic middle plate 120, external sounds can be received by the microphone 400 through the sound receiving hole 1201. Furthermore, by fixing the communication antenna 300 within the communication configuration cavity 1301 between the extended mounting portion 1210 of the plastic middle plate 120 and the plastic lower shell 130, the signal shielding of the communication antenna 300 by the original metal structure can be reduced through the plastic structure. Finally, the microphone 400 is communicatively connected to the display screen 200 via the communication antenna 300. This allows the communication antenna 300 to receive and amplify the signal from the microphone 400 more quickly, and then transmit the amplified signal to the display screen 200, thereby improving the performance of the display screen 200.
[0050] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
