[0043] Please refer to Figure 3 , Figure 4 and Figure 7 , the frame 1 includes a front cover body 12 and a rear cover body 13. The front cover body 12 is disposed on the front side of the flip cover 21, and the rear cover body 13 is disposed on the rear side of the flip cover 21. A left opening, a top opening, and a right opening of the accommodation cavity are formed between the front cover body 12 and the rear cover body 13. The rear opening of the accommodation cavity is disposed on the rear cover body 13. When the flip cover 21 rotates to the closed state, the front cover body 12, the flip cover 21, and the rear cover body 13 are gradually widened from front to back. The overall shape of the hood is narrow in the front and wide in the back, which can optimize the vision of the loader and reduce the obstruction of the driver's vision by the hood. In a further embodiment, the top end of the front cover body 12 is inclined with a narrow upper part and a wide lower part. When the driver observes backward, the wheels of the loader can be seen, so as to locate the position of the whole vehicle through the wheels.
[0044] Please refer toFigure 8 When the flip cover 21 rotates to the closed state, the top surface of the front hood body 12, the top cover 212 and the top surface of the rear hood body 13 are inclined downward from front to back. Figure 8 The dotted line in [reference] is the line of sight S when the driver observes backward. The whole hood tilts backward, which can further optimize the field of vision of the loader, reduce the occlusion of the rear vision of the driver by the hood, improve the overall aesthetics of the hood, and help guide the rainwater to flow out.
[0045] Please refer to Figures 2 to 4 , the left opening of the accommodating cavity includes an upper left opening and a lower left opening, and the right opening of the accommodating cavity includes an upper right opening and a lower right opening. When the flip cover 21 rotates relative to the frame 1 to the unfolded state, the left cover 211 opens the upper left opening of the accommodating cavity, and the right cover 213 opens the upper right opening of the accommodating cavity. When the flip cover 21 rotates relative to the frame 1 to the closed state, the left cover 211 closes the upper left opening of the accommodating cavity, and the right cover 213 closes the upper right opening of the accommodating cavity. The hood assembly 2 further includes a lower left side cover 24 and a lower right side cover 25. The lower left side cover 24 and the lower right side cover 25 are respectively rotatably connected to the frame 1. The lower left side cover 24 rotates relative to the frame 1 to open or close the lower left opening, and the lower right side cover 25 rotates relative to the frame 1 to open or close the lower right opening. The settings of the upper left opening, the lower left opening, the upper right opening, the lower right opening, the lower left side cover 24 and the lower right side cover 25 can provide a more detailed access path for the operator, while ensuring maintenance from more directions, reducing the overall size of the flip cover 21, and making the operation more convenient and labor-saving.
[0046] Please refer to Figure 3 and Figure 5 , a locking member 241 is provided on the lower left side cover 24. The locking member 241 includes a first locking bar 2411 and a second locking bar 2412 that are vertically connected. The first locking bar 2411 is rotatably penetrated through the lower left side cover 24, and the second locking bar 2412 is provided inside the lower left side cover 24. A cooperating bar 14 is provided on the frame 1. When the lower left side cover 24 rotates relative to the frame 1 to close the lower left opening, the first locking bar 2411 rotates relative to the lower left side cover 24 to make the second locking bar 2412 rotate to the inside of the cooperating bar 14 to prevent the lower left side cover 24 from rotating to open the lower left opening. The cooperation of the locking member 241 and the cooperating bar 14 provides a safe locking mechanism, ensuring the stability of the lower left side cover 24 in the closed state, preventing the lower left side cover 24 from accidentally opening, improving the accuracy and safety of the operation, and the rotating method has the characteristics of simple operation. Correspondingly, a locking mechanism is also provided between the lower right side cover 25 and the frame 1, which will not be elaborated here.
[0047] In other embodiments, the first locking bar 2411 can move relative to the lower left side cover 24 and drive the second locking bar 2412 to move into or out of the inner side of the engaging bar 14. Further, similar locking mechanisms are provided between the flip cover 21, the tail cover 22 and the frame 1 in the above embodiments, so as to ensure that the hood can be stably maintained in the normal state, and the overall hood can provide stable and effective protection for the internal components.
