DETAILED DESCRIPTION

[0019] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Combined with reference Figure 1-Figure 4 The utility model provides an engineering vehicle instrument with a camera display, which is arranged on an engineering vehicle, specifically an engineering vehicle instrument installation area, including an instrument housing 1 and a mounting plate 2. The mounting plate 2 is arranged in the instrument installation area of ​​the engineering vehicle. In the present application, the mounting plate 2 can be connected with the front windshield lower trim of the engineering vehicle while maintaining the inconvenience of its structure and the surrounding connection structure, so as to maximize the aesthetics of the connection. A camera display screen 3 and an instrument display screen 4 are arranged on the instrument housing 1. The camera display screen 3 can be used to display the display screen of the camera installed on the engineering vehicle. The instrument display screen 4 is used to display a variety of data on the operation status of the engineering vehicle. A docking frame edge 5 is fixedly connected to the tail of the instrument housing 1, and the docking frame edge 5 is movably arranged on the mounting plate 2. A positioning block 6 is fixedly connected to the tail of the instrument housing 1, and the positioning block 6 is arranged on the inner side of the docking frame edge 5. An internal thread sleeve 8 and a guide column 7 are fixedly connected to the positioning block 6. The inner side of the internal thread sleeve 8 is provided with an internal thread. A plurality of guide columns 7 are provided. An installation drive device for transmitting the internal thread sleeve 8 is provided on the mounting plate 2, and the guide column 7 movably passes through the mounting plate 2.

[0021] The inner surface of the docking frame edge 5 is provided with a sealing edge 11, and the sealing edge 11 is provided with an outward opening. The outward opening can be understood as a trumpet opening. Such a shape design can promote sealing.

[0022] A sealing ring gasket 12 is fixedly connected to the circumferential side of the mounting plate 2, and the docking frame edge 5 is tightly arranged on the sealing ring gasket 12 through the sealing edge 11. The circumferential side of the sealing ring gasket 12 is provided with a docking edge matched with the sealing edge 11. Because the circumferential side of the sealing ring gasket 12 is matched with the specifications of the sealing edge 11, when the docking frame edge 5 is subjected to pressure on the mounting plate 2, the sealing ring gasket 12 can increase the sealing of the connection between the docking frame edge 5 and the mounting plate 2, thereby improving the waterproof and dustproof protection of the connection between the instrument housing 1 and the mounting plate 2.

[0023] The installation drive device includes a self-locking motor 9 fixedly connected to the rear surface of the mounting plate 2 and a transmission screw 10 fixedly connected to the output end of the self-locking motor 9. The transmission screw 10 is rotatably connected to the mounting plate 2, and the transmission screw 10 is threadedly connected to the internal threaded sleeve 8. The transmission screw 10 is driven by the self-locking motor 9 to rotate forward or reverse. Under the linear movement path of the instrument housing 1 linearly limited by the guide column 7, the transmission cooperation between the transmission screw 10 and the internal threaded sleeve 8 can control the instrument housing 1 to move linearly, that is, to move toward or away from the mounting plate 2.

[0024] A pre-tightening sleeve 13 is fixedly passed through the mounting plate 2, and the pre-tightening sleeve 13 can pass through the mounting plate 2 and be fixedly arranged. A slot for inserting the guide column 7 is arranged in the pre-tightening sleeve 13, and the pre-tightening sleeve 13 can be made of hard rubber material. In this way, when the guide column 7 is inserted into the pre-tightening sleeve 13, the connection gap can be reduced while the balance of the guide column 7 can be improved to ensure the connection stability. The pre-tightening sleeve 13 is arranged in a trumpet shape, and the guide column 7 is tightly inserted in the pre-tightening sleeve 13. The trumpet-shaped arrangement of the pre-tightening sleeve 13 is mainly presented at the end position of the pre-tightening sleeve 13, which can facilitate the alignment of the guide column 7 to the pre-tightening sleeve 13.

[0025] The mounting plate 2 is fixedly connected with a mounting ear plate 14, and the mounting ear plate 14 is provided with a mounting hole, and the mounting hole can cooperate with fasteners to fix the mounting plate 2 in the mounting cavity of the engineering vehicle instrument.

[0026] Specifically, when the mounting plate 2 is located in the instrument mounting cavity of the engineering vehicle and is in a fixed setting, the instrument housing 1 can be held by hand and approached to the mounting plate 2, and the guide column 7 is controlled to be aligned with the preload sleeve 13 and inserted and extended. At this time, the movement path of the instrument housing 1 is limited to a straight line, and the transmission screw 10 and the internal threaded sleeve 8 are in an aligned connection state. Then, the self-locking motor 9 is controlled to start, and the rotation of the self-locking motor 9 can make the transmission screw 10 rotate, and the transmission screw 10 is connected to the internal thread of the internal threaded sleeve 8 by the transmission connection, so that the internal threaded sleeve 8 is locked in the transmission. The movement of the path on the movable screw 10 can pull the instrument housing 1 close to the mounting plate 2 until the sealing edge 11 of the docking frame edge 5 is in close contact with the docking edge of the sealing ring gasket 12, which can increase the docking fit. The connection here can not only meet the requirements of waterproof and dustproof protection, but also prevent the connection between the docking frame edge 5 and the mounting plate 2 from deviating. At the same time, since multiple guide columns 7 are inserted in place on the mounting plate 2, the stability of the assembly of the instrument housing 1 can be increased. Since the assembly of the instrument housing 1 is achieved by electric drive, the efficiency of disassembly and assembly of the instrument housing 1 can be improved.

[0027] Similarly, when the instrument housing 1 needs to be removed, the self-locking motor 9 can be controlled to reverse to allow the internal threaded sleeve 8 to be pushed out of the transmission screw rod 10, so that the instrument housing 1 can be directly pulled out and removed.
