Description

Technical Field

[0001] This utility model relates to the field of engineering machinery, and in particular to a manually detachable curved glass door for engineering machinery. Background Technology

[0002] Skid steer loaders, also known as skid steer loaders, multi-purpose engineering vehicles, or multi-purpose engineering machines, are wheeled specialized chassis equipment that uses the difference in linear speed between the wheels on both sides to achieve vehicle steering. Due to structural limitations, skid steer loaders cannot be designed with side doors; instead, doors are designed in the front windshield area, with flat glass panels installed in the doors for observation.

[0003] In existing skid steer loaders, the side visibility from the cab door is limited, creating blind spots. Furthermore, the front windshield door uses flat glass for observation, which prevents observation of the work situation during operation, resulting in low work efficiency and safety. Flat glass also leads to poor lighting in the cab, negatively impacting the operator's driving experience. Additionally, in existing skid steer loaders, the door cannot be quickly detached from the cab after connection, hindering emergency escape. Moreover, the door lacks a windshield wiper mechanism, rendering its operation ineffective. Utility Model Content

[0020] like Figures 1-4 As shown, a manually detachable curved glass door for engineering machinery includes a cab 1 and a door structure 2. The cab 1 is equipped with a front windshield 13. The door structure 2 includes a sealing strip 3, a glass door 4, a mounting frame 5, a hinge structure 9, and a door lock structure 11. The sealing strip 3 and the glass door 4 are connected together, and the glass door 4 is connected to the mounting frame 5. The hinge structure 9 is provided on the glass door 4 and the mounting frame 5. The door lock structure 11 is connected to the glass door 4 and the mounting frame 5. A gas spring 12 is provided inside the cab 1.

[0021] The door structure 2 is installed at the windshield 13 on the driver's cab 1. One end of the gas spring 12 is fixed to the driver's cab 1 with bolts, and the other end is fixedly connected to the mounting frame 5 in the door structure 2. The glass door 4 has a curved structure. The lower end of the mounting frame 5 is provided with a wiper mounting plate, and a protective pad 6 is provided at the wiper mounting plate. The wiper motor is provided on the wiper mounting plate at the lower end of the mounting frame 5, and a wiper blade is connected to the wiper motor. The sealing strip 3 is installed on the glass door 4 by snap-fit. A first rubber pad 7 and a second rubber pad 8 are provided between the glass door 4 and the mounting frame 5, and the glass door 4 and the mounting frame 5 are fixedly connected by connecting screws. The glass door 4 is provided with a rubber sleeve covering the outside of the connecting screws. A third rubber pad 10 is provided between the hinge structure 9 and the glass door 4, and the hinge structure 9 is fixedly connected to the driver's cab 1.

[0022] When installing the door structure 2, first install the sealing strip 3 on the glass door 4. Then, use screws to set the glass door 4, mounting frame 5, hinge structure 9 and door lock structure 11 together. The part of the glass door 4 that contacts the mounting frame 5 is provided with a first rubber pad 7 and a second rubber pad 8. A third rubber pad 10 is provided between the hinge structure 9 and the glass door 4. The assembled glass door 4 and mounting frame 5 are set to the windshield 13 on the driver's cab 1 using the hinge structure 9. The end of the gas spring 12 installed inside the driver's cab 1 is connected to the mounting frame 5. Then, a protective pad 6 is set on the wiper mounting plate at the lower end of the mounting frame 5. After installing the wiper motor, a wiper strip is set on the outside of the glass door 4 and the wiper strip is connected to the wiper motor.

[0023] After the entire door structure 2 is installed, it is put into use. During use, the door structure 2 is stably set up through the door lock structure 11 and the hinge structure 9. A good view can be obtained through the curved glass door 4, increasing safety. When entering or exiting construction machinery, the door lock structure 11 is opened, and the door is opened and closed through the hinge structure 9. During this process, the gas spring 12 provides assistance, helping the operator open and close the door, saving effort. When using construction machinery, activating the wiper motor and swinging the wiper blades can clear the glass door 4, ensuring a clear view. In case of emergency, the door can be manually detached from the cab 1 through the hinge structure 9, enabling emergency escape and increasing safety.

[0024] According to the above implementation scheme, the hinge structure 9 includes a hinge stationary arm 901, a hinge movable arm 902, a mounting plate 903, an elastic connector 904, and a rotary handle 905. The hinge stationary arm 901 is rotatably connected to the hinge movable arm 902, and the hinge stationary arm 901 is mounted on the cab 1.

The mounting plate 903 is set on the glass door 4, and the hinge static arm 901 is fixed on the cab 1. When the door is opened and closed, the entire door is opened and closed normally by rotating on the hinge static arm 901 via the hinge moving arm 902. In case of emergency, the rotating handle 905 at the elastic connector 904 can be rotated to manually disassemble the door, allowing it to detach from the cab 1 for easy emergency escape.

[0026] According to the above implementation scheme, the door lock structure 11 includes a door lock body 1101, a transition bracket 1102, a latch 1103, and an external handle 1104.

The latch 1103 is installed on the cab 1, and the latch 1103 is connected to the door lock body 1101. The external handle 1104 is fixed on the door lock body 1101.

[0027] When installing the door lock structure 11, the door lock body 1101 is connected to the glass door 4 through the transition bracket 1102, and the latch 1103 is installed on the driver's cab 1. The entire door is opened and closed by pulling the outer handle 1104. After the door is closed, the latch 1103 works with the door lock body 1101 to lock it, ensuring the stability of the door closing.

[0028] It should be noted that the curved glass of the glass door 4 improves the driver's cab 1's field of vision, facilitating observation of the engineering situation and enhancing driving safety. A hinge structure 9 is installed on the inner side of the door of the driver's cab 1, with a manually detachable rotating handle 905 within it. The door can be separated from the driver's cab 1 by manually rotating the handle 905, enabling emergency escape and further increasing safety. A structure for installing a wiper motor is located at the lower end of the mounting frame 5, allowing for the installation of a wiper motor and the mounting of wipers on the outside, enabling the wiper function. Furthermore, the glass door 4 uses a rotating shaft on the hinge structure 9 to open and close the door, employing a gas spring 12 to provide assistance during opening and closing, saving effort.
