As an embodiment, the cab side window of the skid steer loader includes a side window frame, a side window panel, a sliding window panel assembly and a mesh panel, the side window panel is mounted on the side window frame, and the side window panel is mounted on the side window frame. An opening is formed on the window panel, the mesh panel is connected with the outer wall surface of the side window panel and corresponds to the opening, and the sliding window panel assembly includes a sliding rail structure and a sliding window slidably connected with the sliding rail structure a panel, the sliding rail structure is connected to the inner wall surface of the side window panel, the sliding window panel has a blocking position to block the opening and slides in a direction away from the opening to expose the opening ventilation position. When the sliding window panel is in the ventilation position, ventilation is carried out through the opening 28. When the sliding window panel is in the blocking position, the side window of the cab is closed; when ventilation is performed through the opening 28, the mesh panel can prevent accidental injury of components outside the cab The driver or limb protrudes out of the window and is squeezed by the moving parts, which plays a protective role. Preferably, the side window panel is fixed on the side window frame by means of gluing.

Since the mesh plate only needs to correspond to the opening 28, and the mesh plate does not need to be connected with the side window frame 25, but is connected with the relatively smooth side window panel 26, so that the poor sealing caused by the connection between the bolt and the frame can be avoided. In the case of easy water seepage and easy entry of dust, it can also avoid damage to the paint on the side window frame and cause the side window frame to rust; on the contrary, it is easier to achieve a tight connection between the mesh plate and the side window panel 26, improving the two The tightness of the joint is not easy to enter dust and water, and the side window frame is not easy to rust; at the same time, there is no need to set up a branch frame in the enclosed area of the side window frame 25 for installing the mesh panel, which avoids the side window panel 26 being divided. It can be divided into several parts, so that the side window panel 26 can be presented as an integral structure, with a better field of vision, which can avoid the blocking of the lateral field of view of the driver by the branch frame, and can reduce the area of the grid to a large extent, so that it can be larger. Minimize the occlusion of the driver's lateral vision, help the driver to observe the working conditions, and improve the driving safety performance.

As an embodiment, the mesh panel and the opening are arranged in the middle of the enclosed area of the side window frame 25 . Since the mesh plate does not need to be connected to the side window frame 25, the opening 28 and the mesh plate can be arranged in the middle of the side window panel 26, the area of the mesh plate and the opening 28 can be set smaller, the middle opening of the side glass is small, and the strength of the side glass better.

As an embodiment, the mesh panel corresponds to the rear of the driver's seat 41 . That is, the mesh plate is located on the rear side of the side window of the cab, which can largely avoid the shielding of the driver's lateral vision by the mesh plate, so that the driver's vision is better; it can also make the ventilation position closer to the driver and improve ventilation. the driver's feelings.

As an embodiment, the mesh panel is located behind the driver's seat 41 . Such a design allows the driver to sit on the driver's seat 41 and the rear opening 28 and the mesh panel are located behind the driver, so as to avoid the mesh panel from blocking the driver's lateral view.

The channel is designed so that the rainwater falling into the sliding rail 27 can be discharged to the outside of the cab to prevent the rainwater from flowing into the interior of the cab. Optionally, as shown in FIG. 1 , the upper slide rail 23 and the lower slide rail 27 extend toward the front of the cab to facilitate operation. As an alternative embodiment, the upper slide rail 23 and the lower slide rail 27 may also extend toward the rear of the cab to reduce occlusion.

As an embodiment, the distance between the top end of the screen plate and the top end of the side window frame 25 is smaller than the distance between the bottom end of the screen plate and the bottom end of the side window frame 25 . That is, the mesh panel is installed at the upper position of the middle of the side window panel 26, so as to make the driver feel better when ventilating.

As an embodiment, the area of the mesh panel is less than a quarter of the area of the side window panel. Since the mesh panel does not need to be connected with the side window frame, the setting position of the mesh panel can greatly reduce the area of the mesh panel while satisfying the driver's ventilation experience, avoiding the need to set a larger area of the mesh panel for the convenience of installation. , causing a certain degree of occlusion of the driver's lateral view.

As an embodiment, the top end of the screen plate is flush with the upper slide rail, and the bottom end of the screen plate is flush with the lower rail. This design is to reduce the area of the screen to a large extent, so as to reduce the shielding of the screen to the driver's side view to a large extent.

The sliding rail structure is fixed on the inner side of the side window panel by means of adhesive, so that the length of the sliding rail structure only needs to meet the blocking position and the ventilation position, avoiding the need to extend the two ends of the sliding rail structure to be able to connect with the side window frame. The position of the 25 connection leads to a longer length of the slide rail structure, which causes unnecessary occlusion of the driver's field of vision. The stencil is fixed on the outside of the side window panel by gluing, which can avoid poor sealing, easy water seepage and easy entry of dust caused by bolts and the side window frame connection. The sealing performance of the connection between the two can be improved, and it is not easy to enter dust and water, and at the same time, it will not damage the paint on the side window frame 25, so that the side window frame 25 is not easy to rust.

The side window of the cab adopts a large-area side window panel 26, a small-area sliding window panel and a mesh panel, which can make the driver's side vision better, help to observe the working conditions, and improve the driving safety performance; the mesh panel is arranged in the The rear side is more conducive to the driver's operation and has better lateral vision; the mesh plate and the slide rail structure are fixed by gluing, which has better sealing performance, does not damage the paint of the cab, and is more conducive to anti-corrosion.

The boom 16 includes an avoidance section 10. When the boom 16 is in the driving position, the avoidance section 10 is located in the area where the boom 16 is close to the side window of the cab. The bottom direction of the frame structure 3 of the skid steer loader is recessed. The avoidance section 10 corresponds to the side window of the cab. Usually, the boom 16 is inclined downward from the rear to the front when the boom 16 is located at the lowest position. The lateral vision is affected, and the height of the rear is higher, but because it is located behind the cab, it will not affect the driver's lateral vision, so the height of the front and rear of the boom 16 can be unchanged, and the height of the middle Between the rear part and the front part, and the middle part of the boom 16 is the part most likely to affect the driver's lateral vision, therefore, the avoidance section 10 located in the middle part is set in the form of a downward depression.

By setting the top surface of the middle portion of the boom 16 corresponding to the side window of the cab in the form of a downward depression, the height of the middle portion of the boom 16 corresponding to the side window of the cab can be reduced, and the distance between the boom 16 and the side of the cab can be reduced. The occluded area increases the driver's side vision.

As an embodiment, the boom 16 further includes a first section 9 and a second section 11 . Along the length direction of the boom 16 , the first section 9 , the avoidance section 10 and the second section 11 The sections 11 are arranged in sequence. When the boom 16 is in the driving position, the rear end of the avoidance section 10 extends to the rear end of the cab, and the front end of the avoidance section 10 extends to the driver seat of the cab. the front part. As shown in FIG. 1 , the first section 9 is between point K and point B, the avoidance section 10 is between point B and point C, and the second section 11 is between point C and the front end of the boom 16 . The front end of the segment 11 (ie the end away from the avoidance segment 10 ) is connected to the bucket 7 of the skid steer loader. That is, when the boom is in the lowest position, the first section 9 is located behind the cab, a part of the second section 11 corresponds to the side window of the cab, and the rest of the second section 11 is located in front of the cab. The height of segment 11 itself is low and will not affect the driver's lateral vision, so there is no need to change the part corresponding to the side window of the cab, only the middle part that is higher in height and affects the driver's lateral vision ( It is sufficient to avoid the height of section 10).

As an embodiment, as shown in FIGS. 8-9 , the top surface of the avoidance section 10 is an arc-shaped surface. Optionally, the bottom surface of the avoidance section 10 is an arc-shaped convex surface, that is, the avoidance section 10 is bent downward as a whole to reduce the height of the avoidance section 10 when it is in the lowest position, while ensuring the rigidity of the avoidance section 10 .

As an embodiment, as shown in FIG. 9 , the top surface of the first segment 9 is a plane. That is, the top surface between point K and point C (the first segment 9 and the avoidance segment 10) is changed from the original form of all straight line segments to the form of straight line segments plus arc segments to reduce the top surface height of the BC segment, Increases side-to-side visibility from the cab. Since the straight segment is easier to process, it is convenient to process the top surface of the first segment 9 in the form of a plane without affecting the lateral view of the cab.
