[0022] like Figure 1 As shown, the intelligent control screen for engineering vehicles in this embodiment of the utility model includes a silicone panel 1, a front cover 2, a glass plate 3, an LCD screen 4, a pressure plate 5, a circuit board 6, a connector 7, a sealing ring 8, a rear cover 9, screws 10, a housing seal 11, and a mounting bracket 12.

[0023] The front cover 2 and the rear cover 9 cooperate to form the main shell of the control screen. The silicone panel 1 is set on the front end of the front cover 2. The glass plate 3 is set on the inside of the front cover 2 and located behind the silicone panel 1. The LCD screen 4 is set behind the glass plate 3. The pressure plate 5 is used to fix the LCD screen 4 to the circuit board 6. The circuit board 6 is connected to the connector 7 for signal transmission. The sealing ring 8 is set at the mating point between the rear cover 9 and the connector 7. The rear cover 9 is locked and fixed to the front cover 2 by screws 10. The housing seal 11 is set at the mating point between the rear cover 9 and the mounting bracket 12. The mounting bracket 12 is used to assemble the control screen onto the engineering vehicle.

[0024] In the above-described design, the front cover 2 and the rear cover 9 cooperate to form the main outer shell, providing installation space and basic protection for internal components such as the silicone panel 1, glass plate 3, LCD screen 4, pressure plate 5, and circuit board 6. Screws 10 lock the rear cover 9 and the front cover 2 together, ensuring the stability of the outer shell structure. A sealing ring 8 is located at the interface between the rear cover 9 and the connector 7, and a housing seal 11 is located at the interface between the rear cover 9 and the mounting bracket 12, forming a multi-layered sealing structure that prevents external dust and moisture from entering the interior. The mounting bracket 12 secures the control panel to the engineering vehicle. Through the cooperation of these components, the overall structure of the control panel is compact, reliably fixed, and its sealing performance is improved. This allows it to adapt to the high vibration and complex environmental conditions of engineering vehicles, protecting internal components from damage and ensuring the normal operation of the control panel.

[0025] The silicone panel 1 is a flexible panel with a tactile structure for operation buttons. The silicone panel 1 and the front end of the front cover 2 are connected by an interference fit, which allows the operator to clearly perceive the operation position and improve the operation feel. The interference fit between the silicone panel 1 and the front end of the front cover 2 can fit tightly, reduce the gap between the two, effectively prevent dust and moisture from entering the control screen from the front end, and enhance the installation firmness of the silicone panel 1 to prevent it from falling off due to vibration.

[0026] The glass plate 3 is made of transparent tempered glass, and a buffer pad is provided between the edge of the glass plate 3 and the inner wall of the front cover 2. The glass plate 3 has high hardness and impact resistance, which can directly provide physical protection for the LCD screen 4 behind it, preventing the LCD screen 4 from being damaged by external impacts; the buffer pad between the edge of the glass plate 3 and the inner wall of the front cover 2 absorbs the impact force generated by the vibration of the engineering vehicle, reduces the impact of vibration on the glass plate 3, prevents the glass plate 3 from breaking due to vibration, and indirectly protects the LCD screen 4.

[0027] The pressure plate 5 is a rigid insulating pressure plate. It has positioning posts adapted to the LCD screen 4 and circuit board 6. These positioning posts pass through the edge of the LCD screen 4 and engage with positioning holes on the circuit board 6. The rigidity of the pressure plate 5 ensures the fixing strength of the LCD screen 4 and circuit board 6, preventing them from loosening during vibration. The positioning posts on the pressure plate 5, passing through the edge of the LCD screen 4 and engaging with the positioning holes on the circuit board 6, achieve precise alignment of the LCD screen 4 and circuit board 6, ensuring a stable connection. Its insulating properties prevent electrical conductivity between the pressure plate 5 and the circuit board 6, protecting the circuit board 6 and ensuring stable signal transmission.

[0028] The sealing ring 8 is an annular rubber sealing ring with a trapezoidal cross-section. Both sides of the sealing ring 8 abut against the rear end face of the connector 7 and the front end face of the rear cover 9, respectively. The annular rubber sealing ring 8 is elastic and can adapt to minor unevenness in the mating surfaces of the components. Its trapezoidal cross-section can more fully fill the gap between the connector 7 and the rear cover 9 when they are locked together, enhancing the sealing effect. The fact that both sides of the sealing ring 8 abut against the rear end face of the connector 7 and the front end face of the rear cover 9 effectively prevents external dust and liquids from entering the interior through the mating area between the connector 7 and the rear cover 9, protecting the connection between the circuit board 6 and the connector 7 from contamination and damage.

[0029] Mounting bracket 12 is a metal bracket with mounting holes adapted to the body of the engineering vehicle. The housing seal 11 is a rubber gasket that matches the shape of the mounting bracket 12. The mounting bracket 12 is securely connected to the rear cover 9. The mounting bracket 12 has high strength, providing a stable mounting base for the control panel, resisting the forces generated by vibrations of the engineering vehicle, and preventing the control panel from loosening. The mounting holes on the mounting bracket 12 are adapted to the body of the engineering vehicle, facilitating a reliable connection between the control panel and the vehicle body. The housing seal 11, a rubber gasket adapted to the shape of the mounting bracket 12, fills the gap between the rear cover 9 and the mounting bracket 12, enhancing the sealing at the joint. The secure connection between the mounting bracket 12 and the rear cover 9 further ensures the overall stability of the control panel installation, allowing the control panel to be stably mounted on the engineering vehicle and adapt to complex working conditions.

[0030] In summary, the intelligent control screen for engineering vehicles according to this utility model embodiment has the following advantages:

[0031] 1. Improved structural stability: The front cover 2 and the rear cover 9 are locked together by screws 10 to form the main shell, providing a stable installation base for internal components; the positioning post of the pressure plate 5, together with the positioning hole of the circuit board 6, ensures that the LCD screen 4 and the circuit board 6 are firmly connected and resist vibration and impact; the metal mounting bracket 12 is adapted to the body of the engineering vehicle through the mounting hole, further ensuring the overall installation of the control screen is stable and preventing loosening during vehicle operation vibration.

[0032] 2. Enhanced Sealing Performance: The silicone panel 1 and the front cover 2 are interference-fitted to prevent dust and moisture from entering; the sealing ring 8 (annular trapezoidal rubber structure) tightly abuts against the connector 7 and the rear cover 9, preventing contaminants from entering through the mating area between the connector 7 and the housing; the enclosure seal 11 (rubber gasket) fills the gap between the rear cover 9 and the mounting bracket 12, forming a third layer of seal. The synergistic effect of these multiple sealing structures significantly improves the control panel's dustproof, waterproof, and oil-proof capabilities.

[0033] 3. Optimized protection performance: The transparent tempered glass plate 3 directly protects the LCD screen 4 and resists external impact; the buffer pads on the edge of the glass plate 3 absorb vibration energy and prevent the glass plate 3 from breaking; the rigid insulating pressure plate 5 not only fixes the internal components, but also prevents the circuit board 6 from generating conductive interference with other components, thus protecting circuit safety.

[0034] 4. Operational reliability assurance: The tactile structure of the silicone panel 1 enhances the operating feel and ensures that operators can operate accurately in complex environments; the robust connection and sealing design of each component reduces operational failures or abnormal signal transmission caused by environmental factors, ensuring the continuous and stable operation of the control panel.

[0035] Working principle of this utility model embodiment:

[0036] The control panel is fixed to the engineering vehicle via mounting bracket 12, forming a stable control unit. Various operating signals of the engineering vehicle (such as engine status, operating parameters, etc.) are transmitted to circuit board 6 via connector 7. After processing the signals, circuit board 6 controls the LCD screen 4 to display the corresponding information. Operators can obtain the vehicle status by observing the LCD screen 4.

[0037] When the operator needs to perform control operations, by pressing the button tactile structure of the silicone panel 1, the operation signal is transmitted through the silicone panel 1 to the internal sensing structure (in conjunction with the circuit board 6), and then processed by the circuit board 6 to generate control commands, which are fed back to the control system of the engineering vehicle through the connector 7 to realize intelligent control of the vehicle.

[0038] Throughout the entire operation, the outer shell formed by the front cover 2 and the rear cover 9 provides physical protection for the internal components; the multiple sealing structure formed by the sealing ring 8, the silicone panel 1, and the housing seal 11 prevents external contaminants from entering and protects core components such as the circuit board 6 and the LCD screen 4; the fixing effect of the pressure plate 5 and the vibration damping effect of the buffer pad ensure that the connection between the LCD screen 4 and the circuit board 6 is stable and the signal transmission is not affected when the vehicle vibrates.

[0039] How to use this utility model embodiment:

[0040] 1. Component assembly: First, connect and fix the connector 7 to the circuit board 6; pass the positioning post of the pressure plate 5 through the edge of the LCD screen 4, so that the positioning post and the positioning hole of the circuit board 6 are matched, and fix the LCD screen 4 and the circuit board 6 as one unit; put the glass plate 3 with the buffer rubber pad into the inside of the front cover 2, and then put the fixed LCD screen 4 and circuit board 6 assembly into the front cover 2, so that the glass plate 3 is in front of the LCD screen 4.

[0041] 2. Shell sealing: Place the sealing ring 8 at the position of the connector 7 at the mating point of the front cover 2 and the rear cover 9, align the rear cover 9 with the front cover 2, and lock it in place with screws 10; install the silicone panel 1 with the front end face of the front cover 2 with an interference fit to complete the assembly of the control panel body.

[0042] 3. Overall installation: Place the housing seal 11 at the mating point between the mounting bracket 12 and the rear cover 9. Use fasteners (such as bolts) to fix the control panel as a whole to the designated installation position on the engineering vehicle through the mounting holes on the mounting bracket 12, ensuring that the mounting bracket 12 and the rear cover 9 are firmly connected.

[0043] 4. Debugging and use: Connect connector 7 to the control circuit of the engineering vehicle. After powering on, check whether the LCD screen 4 displays normally and whether the operation of the silicone panel 1 is sensitive. After confirming that all functions are normal, it can be put into use. Operators operate through the silicone panel 1 and obtain vehicle information through the LCD screen 4.

[0044] In summary, the control panel of this utility model embodiment is adapted to the harsh working conditions of engineering vehicles, extends the service life of core components, reduces maintenance frequency, and improves the reliability of intelligent control of engineering vehicles.
