Description
Technical Field
[0001] The utility model relates to the technical field of special vehicles, in particular to a road sweeper and a door thereof. Background Art
[0002] When the road sweeper is in operation, the left and right sweeping discs at the front of the vehicle usually operate on the ground 45° in front of the door. The driver cannot observe the status of the sweeping discs in real time, resulting in the inability to timely understand the road cleaning situation, which affects the operation efficiency. To solve this problem, the current road sweeper adds cameras to the left and right front parts of the vehicle, and the real-time information of the road surface on both sides is fed back to the display screen on the instrument panel through the camera. The cab can grasp the cleaning status of the front sweeping disc by observing the display screen. However, adding cameras will increase the cost of the vehicle on the one hand, and on the other hand, because the position of the camera is directly above the rear side of the sweeping disc (relative to the forward direction of the vehicle), after a period of cleaning, the lens surface of the camera is contaminated, the clarity decreases, and a good observation effect cannot be achieved. Therefore, how to improve the road sweeper so that the driver can observe the posture of the front sweeping disc and its road cleaning situation in real time has become a technical problem that needs to be solved urgently by those skilled in the art.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1 The embodiment of the utility model provides a door of a road sweeper, including a body and an observation window arranged on the body, the observation window having a first area 11, the first area 11 is located at a position of the body near the front face of the vehicle in the front-to-back direction of the road sweeper, and is located at a position of the body near the lower end in the up-down direction of the road sweeper, and the first area 11 is used to enable the driver in the cab to observe the front sweeping disc of the road sweeper through the observation window. It should be understood that the front-to-back direction of the road sweeper is the front-to-back direction when driving, that is, the head-to-tail direction of the road sweeper, the front face of the vehicle refers to the side where the front windshield of the vehicle is located, and the up-down direction of the road sweeper is the direction from the top of the vehicle to the bottom of the vehicle. For example, when the road sweeper is driving on a horizontal road, the up-down direction of the road sweeper is the vertical direction. The first area 11 of the observation window is located forward and downward on the vehicle door. The driver in the cab looks out toward the first area 11 of the observation window and can see the front sweeping disc of the road sweeper. The front sweeping disc refers to the sweeping disc located at the front of the road sweeper. When the road sweeper is operating, the angle between the sweeping disc and the ground is adjusted to achieve a high cleaning rate under different working conditions.
[0021] In the traditional door structure of a road sweeper, since the front and lower part of the door is an opaque sheet metal structure, the driver cannot easily observe the operation of the front sweeping disc. The door of the utility model is provided with an observation window with the above-mentioned first area 11, so that the driver can observe the posture of the front sweeping disc and its road cleaning situation in real time, so as to timely adjust the angle between the sweeping disc and the ground to ensure a high cleaning rate cleaning effect and avoid repeated operations affecting work efficiency.
[0022] It is easy to understand that the observation window is made of a transparent material such as glass, so that the driver in the vehicle can observe the front sweeper outside the vehicle through the first area 11 of the observation window. In specific practical applications, the size and shape of the observation window can be flexibly set as needed, such as Figure 1As shown, in a preferred embodiment, the observation window has a second area 12 connected to the first area 11, the second area 12 is located above the first area 11 in the vertical direction of the road sweeper, and the end of the second area 12 away from the first area 11 is located in the upper half of the body. This arrangement can make the observation window have a larger size, so that the driver can see a wider field of view outside the vehicle through the observation window. Further preferably, the proportion of the observation window in the vertical direction of the road sweeper to the body is not less than 80%.
[0023] like Figure 1 As shown, in order to facilitate the arrangement of some other components on the door, in this embodiment, the observation window is located in the front half of the body in the front-to-back direction of the road sweeper, that is, the proportion of the observation window in the front-to-back direction of the road sweeper is not more than 50%. The first side 101 of the observation window close to the front face of the vehicle is usually arranged parallel to the contour line of the front edge of the door. For example, in this embodiment, the first side 101 is set as a curve. The second side 102 of the observation window away from the front face of the vehicle is usually set in a specific shape according to the arrangement of other components in the rear half of the body. For example, in this embodiment, the second side 102 is set as a straight line.
[0024] In order to make the observation window have a larger area, in this embodiment, the first side 101 and the second side 102 are made to have the same size in the vertical direction of the road sweeper. Figure 1 As shown, the third side 103 of the observation window close to the upper end of the body and the fourth side 104 far from the upper end of the body meet the parallel condition, the third side 103 connects the first end of the same side of the first side 101 and the second side 102, and the fourth side 104 connects the second end of the same side of the first side 101 and the second side 102. Specifically, the third side 103 and the fourth side 104 are arranged parallel to the front and rear directions of the road sweeper, that is, when the road sweeper travels on a horizontal road surface, the third side 103 and the fourth side 104 are parallel to the road surface. Of course, in other embodiments, the third side 103 and the fourth side 104 can also be arranged to be non-parallel.
[0025] like Figure 1 As shown, in this embodiment, the observation window is a quadrilateral. In a preferred embodiment, the four corners of the observation window are set to be arc-shaped, that is, the adjacent sides are rounded. Of course, in other embodiments, the observation window can also be set to other shapes, such as rectangular, circular, etc.
[0026] In a preferred embodiment, the body is provided with a window 21 and an interlayer 300 located below the window 21, the door includes a window block body 22 movably connected to the body and a driving device located in the interlayer 300, the driving device is used to drive the window block body 22 to rise and fall to close and open the window 21, the window 21 and the first area 11 of the observation window are distributed along the diagonal of the door, that is, the position of the window 21 on the door is backward and upward. It should be noted that the specific structure and working principle of the driving device can refer to the traditional window lifter, and the driving device will not be described in detail herein. Specifically, the driving device can be electric or manual, and the utility model does not limit this.
[0027] In a preferred embodiment, the window block 22 is made of transparent glass, so that even if the window block 22 rises to block the window 21, the driver can see the situation outside the vehicle through the window 21. Of course, the window block 22 can also be made of other transparent materials.
[0028] like Figure 1 As shown, in this embodiment, the upper edge of the observation window, i.e., the third side 103, is at the same height as the upper edge of the window 21, and the entire area of the observation window is transparent, so the second area 12 of the observation window can, together with the window 21, provide the driver with a wider horizontal field of vision, thereby facilitating the driver to timely grasp the surrounding traffic conditions during driving. In this embodiment, the observation window is fixedly connected to the body of the vehicle door, i.e., the observation window is closed and cannot be opened. In other embodiments, the observation window can also be set to be openable, for example, the observation window can be installed on the body of the vehicle door via hinges. It should be noted that Figure 1 The door shown in the exemplary embodiment is the left door of the road sweeper, which rotates toward the front of the vehicle when opened, so the door handle 400 is set near the rear side of the door. In other embodiments, if the left door is opened by rotating toward the rear of the vehicle, the door handle 400 can be adaptively set near the front side of the door. In addition, the door described in the above embodiment is also applicable to the right door of the road sweeper. Since the left and right doors of the road sweeper are usually symmetrically arranged, the structure of the right door can refer to Figure 1 The left door is shown for understanding.
