DETAILED DESCRIPTION

[0028] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0029] The universal control panel for mobile machinery according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0030] like Figures 1 to 3As shown, the universal control panel for mobile machinery of the embodiment of the present application may include a mounting frame 100 , a slide rail frame 200 , a display screen 300 , an integrated circuit board 400 , a mounting plate 500 , an elastic pull rod 600 and a spring 700 .

[0031] The mounting frame 100 is arranged at the mounting position, such as an operating console in the cab or an operating platform of the equipment body.

[0032] The two slide rail frames 200 are slidably arranged on both sides of the mounting frame 100, respectively. The display screen 300 is arranged above the two slide rail frames 200. The integrated circuit board 400 and the mounting plate 500 are respectively arranged at the bottom of the two slide rail frames 200 and are respectively connected to the mounting frame 100 through springs 700.

[0033] As a possible scenario, the display screen 300 uses a high-resolution, high-brightness liquid crystal display (LCD) or an organic light-emitting diode display (OLED) to ensure that the operator can clearly read the displayed information, such as the equipment's operating parameters, working status, fault prompts, navigation information (if applicable), etc., under various lighting conditions.

[0034] Among them, Figure 4 and Figure 5 As shown, a slot 201 is provided on the slide rail frame 200 connected to the integrated circuit board 400 , and the display screen 300 and the integrated circuit board 400 are connected via a connecting wire 401 disposed in the slot 201 .

[0035] It should be noted that the integrated circuit board 400 integrates multiple electronic components and electronic circuits, such as a microprocessor, a memory chip, a communication module, an input / output interface circuit, etc., to control various functions of the mobile machine and process data.

[0036] like Figure 6 As shown, one end of the elastic pull rod 600 is arranged on the mounting frame 100, and the other end is arranged in the track groove 501 of the mounting plate 500, wherein, after the slide rail frame 200 is pushed toward the mounting frame 100, the elastic pull rod 600 slides in the track groove 501 and limits the mounting plate 500; after the slide rail frame 200 is pushed again, the elastic pull rod 600 cancels the limit on the mounting plate 500, and due to the reset effect of the spring 700, the slide rail frame 200 is ejected.

[0037] It should be noted that when the control panel needs to be assembled, the relevant staff will first push the slide rail frame 200 along the mounting frame 100. During the pushing and pressing process, the elastic pull rod 600 slides in the track groove 501 of the mounting plate 500. As the pushing and pressing action continues, the elastic pull rod 600 clamps the mounting plate 500. At this time, the spring 700 is in a stretched state, and the display screen 300, the integrated circuit board 400 and the entire slide rail frame 200 are fixed on the mounting frame 100. At this time, the equipment is operating normally, and the operator performs human-computer interaction through the display screen 300 to control the mobile machinery.

[0038] When the integrated circuit board 400 needs to be maintained, upgraded or its functions expanded, the slide rail frame 200 is pushed again to move the elastic pull rod 600, thereby canceling the limit on the mounting plate 500. At the same time, the spring 700, which was originally in a stretched state, elastically recovers and pops the slide rail frame 200 outward. The staff only needs to disassemble the display screen 300 to perform related operations on the integrated circuit board 400, which greatly reduces the cumbersome disassembly process in the traditional method, improves operating efficiency, and reduces maintenance costs and equipment downtime.

[0039] To clearly illustrate the above embodiment, in one embodiment of the present application, Figure 6 As shown, the track groove 501 includes an inclined groove 5011 , a rotary groove 5012 , a retention groove 5013 and a straight groove 5014 .

[0040] Among them, the inclined groove 5011, the rotary groove 5012, the retention groove 5013 and the straight groove 5014 are connected end to end in sequence; and the groove depths of the inclined groove 5011, the rotary groove 5012, the retention groove 5013 and the straight groove 5014 increase linearly in sequence.

[0041] In addition, one end of the elastic pull rod 600 is rotatably disposed on the mounting frame 100 , and the other end is bent and extends into the track groove 501 .

[0042] It should be noted that the revolving groove 5012 is an arc-shaped structure, which is used to guide the elastic pull rod 600 to rotate from the inclined groove 5011 to the retaining groove 5013.

[0043] As a possible situation, the joints of the inclined groove 5011, the rotating groove 5012, the retaining groove 5013 and the straight groove 5014 are all smoothed to avoid the elastic pull rod from getting stuck and ensure that the elastic pull rod can move smoothly in the track groove.

[0044] Specifically, if Figures 1 to 7As shown, in the initial state (i.e., when the mobile machine is not operating the control panel), the bent portion of the elastic pull rod 600 is located in the retaining groove 5013 of the track groove 501, and the retaining groove 5013 is used to tighten and limit the elastic pull rod 600 to prevent the mounting plate 500 from moving, thereby making the slide rail frame 200, the display screen 300 and the integrated circuit board 400 in a stable state, and the spring 700 is in a stretched state.

[0045] When the operator needs to maintain, upgrade or troubleshoot the integrated circuit board 400, the relevant staff pushes the slide rail frame 200 toward the mounting frame 100. As the slide rail frame 200 moves, the mounting plate 500 is forced to move with it, so that the retention groove 5013 squeezes the elastic pull rod 600, so that the elastic pull rod 600 is pushed out of the retention groove 5013 and into the straight groove 5014. At this time, the elastic pull rod 600 loses its limiting effect on the track groove 501, and due to the restoring effect of the spring 700, the spring 700 contracts and pulls the slide rail frame 200 to pop out, so that the display screen 300, the integrated circuit board 400 and the mounting plate 500 are popped out with it. As the mounting plate 500 pops out, the end of the elastic pull rod 600 slides in the straight groove 5014 until it reaches the connection between the straight groove 5014 and the inclined groove 5011.

[0046] The relevant staff only needs to disassemble the display screen 300 to expose the integrated circuit board 400, thereby realizing the maintenance or function expansion operation of the integrated circuit board 400.

[0047] After maintaining or expanding the functions of the integrated circuit board 400, the relevant staff pushes the slide rail frame 200 toward the mounting frame 100. At this time, the elastic pull rod 600 is located at the connection between the straight groove 5014 and the inclined groove 5011, and the groove depth of the inclined groove 5011 is greater. When the slide rail frame 200 is pushed, the connecting plate follows the movement, so that the elastic pull rod 600 gradually slides toward the rotating groove 5012 under the action of the inclined surface of the inclined groove 5011, and enters the retaining groove 5013 under the guidance of the rotating groove 5012. The bent part of the elastic pull rod 600 is stuck in the retaining groove 5013, thereby limiting the mounting plate 500 and completing the installation.

[0048] In one embodiment of the present application, a clamping pin 101 is disposed at the bottom of the mounting frame 100 , and the clamping pin 101 is clamped at the mounting position.

[0049] It should be noted that a slot or snap-in structure matching the snap-in pin 101 is pre-designed at the installation position, and relevant staff can snap the snap-in pin 101 on the mounting frame 100 into the corresponding slot or snap-in structure by pressing the entire device.

[0050] In one embodiment of the present application, Figure 2 and Figure 4 As shown, the two slide rail frames 200 are respectively provided with slide rail grooves 202 on the opposite surfaces thereof, and the two sides of the mounting frame 100 are respectively connected to the corresponding slide rail grooves 202 .

[0051] It should be noted that different structures and connection methods of the slide rail groove 202 may be selected according to specific application scenarios and performance requirements of the mobile machinery.

[0052] For example, in harsh working environments, such as mines and construction sites, the slide rail groove 202 is made of materials with better wear resistance and corrosion resistance, which can ensure that the control panel always maintains good performance during long-term use and reduce wear and failures caused by environmental factors; and in some mobile machinery with high requirements on operating accuracy, such as precision measuring equipment or high-end engineering machinery equipment, a high-precision guide rail slider connection method is selected.

[0053] For example, in the design of the control panel of the excavator, since the excavator will generate strong vibrations and impacts during operation, a dovetail slide groove 202 is used in combination with a rolling bearing connection method to ensure the stability and smoothness of the slide frame 200 during push and pop-up operations, while effectively resisting the impact of vibrations and impacts on the control panel structure and protecting the normal operation of key components such as the display screen 300 and the integrated circuit board 400.

[0054] To clearly illustrate the above embodiment, in one embodiment of the present application, Figure 2 and Figure 4 As shown, the tops of the two slide rail frames 200 are respectively provided with first placement grooves 203 , and the two sides of the display screen 300 are respectively arranged in the corresponding first placement grooves 203 and are locked by quick-release bolts.

[0055] It should be noted that the bolt head of the quick-release bolt can be butterfly-shaped or T-shaped, etc., which is convenient for operators to tighten and loosen manually without the help of complicated tools. In an outdoor construction environment, if temporary maintenance work on the control panel is required, the relevant staff can push and press the display screen 300 and the integrated circuit board 400 to pop out, and manually disassemble the quick-release bolt to reduce the dependence on professional tools in the outdoor construction environment.

[0056] To clearly illustrate the above embodiment, in one embodiment of the present application, Figure 2 and Figure 4 As shown, the bottoms of the two slide rail frames 200 are respectively provided with second placement grooves 204 , and the integrated circuit board 400 and the mounting plate 500 are respectively arranged in the two second placement grooves 204 and locked by bolts.

[0057] It should be noted that the second placement slot 204 of the slide rail frame 200 connected to the integrated circuit board 400 can be set according to the size of the components on the integrated circuit board 400 to avoid interference between the top of the integrated circuit board 400 and the bottom of the mounting frame 100.

[0058] In one embodiment of the present application, Figure 2 and Figure 5 As shown, an expansion interface 402 is provided on the integrated circuit board 400 .

[0059] It should be noted that the expansion interface 402 can adopt a standard interface form, such as a USB interface, an HDMI interface, an Ethernet interface, a CAN bus interface, etc., and can be connected to external expansion devices such as sensors, communication modules, intelligent control terminals, etc. according to actual needs to achieve the upgrade and customization of the mobile machinery functions.

[0060] For example, an external temperature sensor is connected through a USB interface to monitor the temperature of key parts of the equipment in real time, and the data is transmitted to the integrated circuit board 400 for processing and display; or an engine control module is connected through a CAN bus interface to achieve optimized control of engine performance.

[0061] In one embodiment of the present application, hanging rings are provided on the integrated circuit board 400, the mounting plate 500 and the mounting frame 100, and one end of the spring 700 is hooked on the hanging ring on the integrated circuit board 400 or the mounting plate 500, and the other end is hooked on the hanging ring on the mounting frame 100.

[0062] As another possible situation, connecting plates are provided on the integrated circuit board 400, the mounting plate 500 and the mounting frame 100, one end of the spring 700 is connected to the connecting plate on the integrated circuit board 400 or the mounting plate 500, and the other end is connected to the connecting plate on the mounting frame 100.

[0063] It should be noted that the elastic coefficient of the spring 700 can be selected and adjusted according to the specific application scenario of the control panel and the required pop-up force. In situations where frequent maintenance operations are required, a spring 700 with a smaller elastic coefficient is selected to allow operators to push the slide rail frame 200 more easily. In situations where higher stability is required, a spring 700 with a larger elastic coefficient is selected to ensure the firmness of the connection between the components during normal use.

[0064] In one embodiment of the present application, an indicator light is provided on the display screen 300 , and the indicator light is connected to the integrated circuit board 400 for displaying the working status of the integrated circuit board 400 .

[0065] For example, when the integrated circuit board is operating normally, the indicator light is green; when a fault occurs or maintenance is required, the indicator light is red, so that the operator can quickly determine the working status of the integrated circuit board and provide more timely feedback response.

[0066] In summary, according to the universal control panel for mobile machinery of the embodiment of the present application, the sliding limit of the elastic pull rod 600 in the track groove 501 and the elastic recovery of the spring 700 cooperate to realize the limited installation and pop-up of the display screen 300 and the integrated circuit board 400. It is only necessary to disassemble the display screen 300 to maintain or expand the functions of the integrated circuit board 400, thereby improving the operating efficiency of relevant personnel.
