[0042] Specifically, the bracket 20 is arranged inside the bus front wall 10, the door plate 21 is adapted to and arranged on the front compartment opening 101, and two connecting rod mechanisms 22 are symmetrically arranged between the door plate 21 and the bracket 20 for connecting the door plate 21 and the bracket 20, and the front compartment opening 101 is opened and closed by the two connecting rod mechanisms 22. Specifically, one end of the connecting rod mechanism 22 is rotatably arranged on the bracket 20, and the other end of the connecting rod mechanism 22 is rotatably arranged on the door plate 21, that is, the other end of the connecting rod mechanism 22 connected to the door plate 21 is a movable end, and the movement of the door plate 21 can drive one end of the connecting rod mechanism 22 to rotate around the bracket 20, so that the door plate 21 can be pulled to translate and lift outside the bus front wall 10, that is, the front compartment opening 101 is in an open state (such as Figure 2As shown). In this way, the front compartment opening 101 can be opened and closed by two connecting rod mechanisms 22, which has a simple structure and is easy to operate.

[0043] In addition, at least one support member 23 is arranged between the bracket 20 and the connecting rod mechanism 22. One end of the support member 23 is rotatably set on the bracket 20, and the other end of the support member 23 is rotatably set on the connecting rod mechanism 22. The door plate 21 is lifted and translated to the outside of the bus front wall 10 and then fixed in position by the support member 23, so that the door plate 21 is fixed in a position above and in front of the front compartment opening 101, which is convenient for personnel to approach the front compartment opening 101 and inspect and repair the accessories installed in the bus front wall 10.

[0044] like Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the link mechanism 22 includes a first link 221 and a second link 222, one end of the first link 221 is rotatably set at the top of the bracket 20, and the other end of the first link 221 is rotatably set at the middle of the door plate 21; one end of the second link 222 is rotatably set at the middle of the bracket 20, and the other end of the second link 222 is rotatably set at the bottom of the door plate 21. That is, one end of the link mechanism 22 is rotatably set at the middle and upper area of ​​the bracket 20, and the other end of the link mechanism 22 is rotatably set at the middle and lower area of ​​the door plate 21, that is, the link mechanism 22 is set across the width direction of the door plate 21, so that the connection between the door plate 21 and the bracket 20 is more stable, so that the door plate 21 can be smoothly translated and lifted toward the outside of the front wall 10 of the bus.

[0045] In addition, the other end of the support member 23 is rotatably disposed on the second connecting rod 222, and the second connecting rod 222 is supported by the support member 23, thereby supporting the door plate 21, so as to fix the position of the door plate 21 for easy maintenance.

[0046] like Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the middle portion of the first connecting rod 221 is tilted toward the inside of the bus front panel 10 to avoid interference between the first connecting rod 221 and the contour edge of the front compartment opening 101 when the compartment door panel 21 is translated toward the outside of the bus front panel 10, and one end of the first connecting rod 221 is bent to form a U-shaped bending portion 2211 for avoiding the front compartment opening 101. The U-shaped end of the U-shaped bending portion 2211 can avoid the contour edge of the front compartment opening 101 when the compartment door panel 21 is lifted upward, to ensure that the compartment door panel 21 can be smoothly translated and lifted toward the outside of the bus front panel 10.

[0047] like Figure 3 , Figure 4 and Figure 5As shown, the present embodiment further includes a balancing rod 24, which is arranged in the horizontal direction, and is located at the bottom of the door panel 21 and arranged between the two second connecting rods 222. Since the force applied to the door panel 21 when the front hatch 101 is opened and closed is concentrated in the middle and lower areas of the door panel 21, a horizontal balancing rod 24 is arranged at the bottom of the door panel 21 to connect the left and right second connecting rods 222, so that the left and right connecting rod mechanisms 22 can move synchronously when the front hatch 101 is opened and closed, thereby ensuring that the door panel 21 can be smoothly translated and lifted outside the front wall 10 of the bus.

[0048] like Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, an adapter plate 2221 is provided on the second connecting rod 222, one end of the support member 23 is rotatably provided on the bracket 20, and the other end of the support member 23 is rotatably provided on the adapter plate 2221. The adapter plate 2221 is provided to facilitate the disassembly and assembly of the support member 23, and to facilitate replacement when the support member 23 is damaged.

[0049] In a preferred embodiment, the support member 23 is a gas spring, which can be extended and retracted to cooperate with the action of the connecting rod mechanism 22 when the front compartment opening 101 is opened and closed, and the gas spring has a high bearing capacity and can support and fix the compartment door panel 21.

[0050] like Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, a handle 211 is provided at the bottom of the door panel 21, and a groove 102 connected to the handle 211 is provided on the bus front wall 10 at the bottom of the front hatch 101. In this way, the door panel 21 can be pulled outward through the handle 211 by reaching into the groove 102, and then the door panel 21 can be lifted and moved outward to open the front hatch 101 for maintenance. The handle 211 is provided to facilitate pulling the door panel 21.

[0051] like Figure 5 and Figure 6 As shown, in this embodiment, the contour edge of the top of the front warehouse opening 101 extends outward from the front wall 10 of the bus to form a first embedded wall 1011, and the contour edge of the door panel 21 extends into the front wall 10 of the bus to form a second embedded wall 212 that is clipped to the first embedded wall 1011.

[0052] Specifically, since one end of the connecting rod mechanism 22 is rotatably set in the middle and upper areas of the bracket 20, and the other end of the connecting rod mechanism 22 is rotatably set in the middle and lower areas of the door plate 21, the middle and bottom parts of the door plate 21 can be connected to the bracket 20 through the connecting rod mechanism 22. Furthermore, by snapping the first embedded wall 1011 and the second embedded wall 212 together, support can be provided for the top of the door plate 21, so that the door plate 21 can be more firmly fixed on the front opening 101 when the front opening 101 is closed, thereby avoiding the shaking of the door plate 21 during the driving of the bus.

[0053] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
