[0022] To make the purpose, technical solutions, and advantages of the implementation of the present utility model clearer, the present utility model will now be further described in detail with reference to the accompanying drawings and the following embodiments, so that the public can better master the implementation method of the present utility model. The specific implementation scheme of the present utility model is as follows:

[0023] An installation structure of an armrest box for an engineering machinery seat includes a mounting plate 1. A seat is provided on the upper end surface of the mounting plate 1. A pin shaft 2 is provided on one side of the mounting plate 1. The central axis of the pin shaft 2 is coplanar or parallel to the mounting plate 1, and the pin shaft 2 is arranged parallel to the central axis of the seat. Here, the central axis of the seat refers to the horizontal line passing through the middle of the seat from front to back. An armrest box 3 is provided on one side of the mounting plate 1. The armrest box 3 is connected to the mounting plate 1 in a hinged structure manner through the pin shaft 2. With the above structure arranged, the armrest box can flip towards the door after being opened, does not occupy the space behind the seat, and can also increase the aisle space, meeting the needs of the driver in a narrow cab to enter the seat.

[0024] It should be noted that a lock body assembly for locking the armrest box 3 is also provided. The lock body assembly includes a lock nose 4 and a latch 5 that cooperates with the lock nose 4. The lock nose 4 is connected to the mounting plate 1 in a fixed structure manner, and the latch 5 is connected to the armrest box 3. Here, the lock body assembly is the lock body assembly of the armrest box with the application number CN202311153966.4, which is an existing structure and will not be elaborated further. The lock body can be driven by the operating rod to unlock from the lock nose, and the lock body and the lock nose can be locked after collision.

[0025] Specifically, the mounting plate 1 is provided with a base A6 in a fixed structure manner, and the lower part of the armrest box 3 is provided with a base B7 in a fixed structure manner. The base B7, the base A6, and the pin shaft 2 form a hinge structure, facilitating the flipping of the armrest box.

[0026] It should be elaborated that the mounting plate 1 is provided with a support plate 8 in a fixed structure manner. The support plate 8 is connected to the lock nose 4 in a fixed structure manner, lifting the lock nose 4 to a certain height to cooperate with the latch 3, making the lock body assembly away from the pin shaft 2, and the force form is more reasonable.

[0027] Furthermore, a handle 9 is provided on the outer side of the armrest box 3 in a fixed structure manner, facilitating the flipping of the armrest box.

[0028] A groove structure 10 is provided on the front side wall of the armrest box 3. In the open state, when the driver turns around to get out of the car, the driver can place the leg here, facilitating getting up.

[0029] The working principle and process of the present utility model are as follows:

[0030] When the driver needs to get out of the car, first open the car door, pull the operating rod to unlock the latch 5 from the lock nose 4, push the armrest box 3 towards the car door direction. The armrest box 3 drives the base B7 to rotate around the pin shaft 2 until the base B7 abuts against one side of the seat, and the armrest box is in a flat state. The driver turns around and places the leg in the groove structure 10. At this time, the driver gets up facing the car door and can avoid the obstruction of the steering wheel, completing the detachment from the seat.
