Description

Technical Field

[0001] The utility model relates to the field of engine control devices, in particular to an engine remote control device. Background Art

[0002] The engine remote control device is an advanced control system, mainly used for remotely operating and monitoring functions such as starting, stopping, and adjusting the operating state of the engine. This device usually combines electronic control technology, wireless communication technology, and computer programs, enabling operators to safely and efficiently control various operations of the engine when away from the physical location of the engine. It is widely used in engine operation scenarios that require remote monitoring or in dangerous and inaccessible environments, such as marine vessels, remote power stations, construction machinery, agricultural machinery, unmanned aerial vehicles, and certain special vehicles.

[0003] For the existing engine remote control device, the service life of the control device is extended through the cooperation of structures such as a support shaft, a first moving plate, a second moving plate, a rotating plate, and a rotating shaft. The top cover is opened upward, causing the top cover to drive the rotating plate to rotate upward. The rotating plate rotates upward along the straight groove of the sliding groove through the second fixed shaft. The rotating shaft slides along the arc groove of the sliding groove through the rotating plate. The second moving plate slides along the arc groove through the rotating shaft, causing the first moving plate to rotate upward through the second moving plate, and the first moving plate drives the support shaft to rotate. When the rotating shaft slides to the top of the arc groove, the top cover is perpendicular to the protection box, and the top cover is opened. Then, commands can be input into the control display screen. After the command input is completed, by rotating the top cover downward, the device moves in the reverse direction, causing the top cover to be clamped with the protection box, and the top cover is closed, making the control device not easily damaged and extending the service life of the control device.

[0004] However, after the top cover is opened, there is a lack of an effective fixing mechanism to maintain its open state. This may not only cause the top cover to accidentally close during operation, interrupting the ongoing command input or viewing process, leading to operation errors or delays, but also may cause premature wear of mechanical components due to frequent unexpected closures, affecting the stability and durability of the entire control device, and thus shortening its service life.

[0005] Therefore, it is necessary to provide a new engine remote control device to solve the above technical problems. Summary of the Utility Model

[0006] To solve the above technical problems, the utility model provides an engine remote control device.

[0007] The engine remote control device provided by the utility model includes a control display screen and a protective box arranged outside the control display screen. Both ends of the protective box are respectively provided with a connected straight chute and a curved chute. The outside of the protective box located at the straight chute is respectively fixedly connected with a first limiting block and a second limiting block;

[0008] The top of the protective box is also provided with a top cover. Both ends of the bottom of the top cover are fixedly connected with rotating plates. The tops of both ends of the rotating plates are respectively fixedly connected with rotating rods. One end of the rotating rod away from the protective box is provided with a limiting member adapted to the first limiting block and the second limiting block. Both ends of the bottom of the rotating plates are fixedly connected with rotating shafts. The rotating rods and the rotating shafts are slidably connected in the straight chute, and the rotating shafts can be slidably connected in the curved chute through the rotating rods.

[0009] Further, a rotating handle is fixedly connected to the top of the top cover. The rear side of the top cover is bent downward to fit with the top wall of the protective box.

[0010] Further, the height of the control display screen is lower than the height of the protective box.

[0011] Further, a plurality of first semi-circular grooves are formed in the first limiting block, and a second semi-circular groove is formed in the second limiting block.

[0012] Further, the limiting member includes a sliding bracket slidably connected to the rotating rod. Two semi-circular blocks are respectively fixedly connected to one side of the sliding bracket, and the semi-circular blocks are adapted to the first semi-circular groove and the second semi-circular groove. A spring is also arranged on the rotating rod, and both ends of the spring are respectively fixedly connected with the sliding bracket and the side wall of the rotating rod.

[0013] Further, a pulling handle is fixedly connected to one end of the sliding bracket away from the semi-circular block.

[0014] Compared with the related art, the engine remote control device provided by the utility model has the following beneficial effects:

[0015] For this engine remote control device, by disengaging the limiting member from the second limiting block and sliding the top cover upward until the rotating rod fits with the inner top wall of the straight chute, at this time the rotating shaft is at the position of the curved chute. By rotating the top cover, the rotating shaft slides in the curved chute, and after reaching the appropriate position, the limiting member is engaged with the first limiting block to complete the angle fixation of the top cover. This not only prevents the top cover from closing under unexpected conditions, but also provides great convenience for users, improving the intuitiveness and convenience of operation.

[0021] The present utility model will be further described below in conjunction with the accompanying drawings and implementation manners.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 Schematic diagram of the state structure of the engine remote control device provided by the present utility model Figure 1 ; Figure 2 Schematic diagram of the state structure of the engine remote control device provided by the present utility model Figure 2 ; Figure 3 Schematic diagram of the state structure of the engine remote control device provided by the present utility model Figure 3 ; Figure 4 Schematic diagram of the structure of the sliding bracket provided by the present utility model.

[0023] In the specific implementation process, as Figures 1 to 4 shown, the engine remote control device provided by the present utility model includes a control display screen 1 and a protective box 2 provided outside the control display screen 1. The two ends of the protective box 2 are respectively provided with a connected straight chute 3 and a curved chute 4. The outside of the protective box 2 at the position of the straight chute 3 is respectively fixedly connected with a first limiting block 5 and a second limiting block 7;

[0024] A top cover 9 is also provided on the top of the protection box 2. At both ends of the bottom of the top cover 9, rotating plates 11 are fixedly connected. At the tops of both ends of the rotating plates 11, rotating rods 12 are respectively fixedly connected. At one end of the rotating rod 12 away from the protection box 2, a limiting member adapted to the first limiting block 5 and the second limiting block 7 is provided. At the bottoms of both ends of the rotating plates 11, rotating shafts 13 are fixedly connected. The rotating rods 12 and the rotating shafts 13 are slidably connected in the straight chute 3, and the rotating shaft 13 can be slidably connected in the curved chute 4 through the rotating rod 12. A rotating handle 10 is fixedly connected to the top of the top cover 9. The rear side of the top cover 9 is bent downward and is attached to the top wall of the protection box 2.

[0025] By detaching the limiting member from the second limiting block 7 and sliding the top cover 9 upward until the rotating rod 12 is in contact with the inner top wall of the straight chute 3. At this time, the rotating shaft 13 is at the position of the curved chute 4. By rotating the top cover 9, the rotating shaft 13 slides in the curved chute 4. After reaching a suitable position, the limiting member is engaged with the first limiting block 5 to complete the angle fixation of the top cover 9, preventing accidental closing. At the same time, it also facilitates the user to fix the top cover 9 at a specified position, facilitating the operation and control of the display screen 1.

[0026] The height of the control display screen 1 is lower than the height of the protection box 2 to prevent the top cover 9 on the protection box 2 from colliding with the control display screen 1 when the top cover 9 is closed.

[0027] A plurality of first semi-circular grooves 6 are formed in the first limiting block 5, and a second semi-circular groove 8 is formed in the second limiting block 7. The limiting member includes a sliding bracket 14 slidably connected to the rotating rod 12. On one side of the sliding bracket 14, two semi-circular blocks 15 are respectively fixedly connected, and the semi-circular blocks 15 are adapted to the first semi-circular grooves 6 and the second semi-circular grooves 8. A spring 17 is also provided on the rotating rod. Both ends of the spring 17 are fixedly connected to the sliding bracket 14 and the side wall of the rotating rod respectively. A pulling handle 16 is fixedly connected to the end of the sliding bracket 14 away from the semi-circular blocks 15;

[0028] The working principle provided by the present utility model is as follows: When the present utility model is specifically implemented, by detaching the limiting member from the second limiting block 7 and sliding the top cover 9 upward until the rotating rod 12 is in contact with the inner top wall of the straight chute 3. At this time, the rotating shaft 13 is at the position of the curved chute 4. By rotating the top cover 9, the rotating shaft 13 slides in the curved chute 4. After reaching a suitable position, the limiting member is engaged with the first limiting block 5 to complete the angle fixation of the top cover 9, preventing accidental closing. At the same time, it also facilitates the user to fix the top cover 9 at a specified position, facilitating the operation and control of the display screen 1;

[0029] When the top cover 9 is in the closed state, the semi-circular block 15 at the bottom fits with the second limiting semi-circular groove 8 of the second limiting block 7, and is kept stable due to the extrusion force of the spring 17. When it is necessary to open the top cover 9, the sliding bracket 14 is pulled by pulling the handle 16, thereby squeezing the spring 17 and separating the semi-circular block 15 from the second limiting semi-circular groove 8 of the second limiting block 7. Before contacting the first limiting block 5, it is in a stretched state to avoid collision. After the angle at which the top cover 9 needs to be fixed is determined, it is docked with the first semi-circular groove 6 on the first limiting block 5 that matches it, and stability is achieved through the extrusion force of the spring 17, completing the angle limitation of the top cover 9.
