Through the setting of the transparent display board 2 made of reinforced plastic, the advertising picture placed on the display board 2 can be better displayed, improving the applicability.

[0030] Furthermore, a clamping groove for inserting the clamping plate 201 is formed in the display board 2, and the clamping groove communicates with the installation groove 101. Through the setting of the clamping groove and the clamping plate 201, the connection strength and stability between the display board 2 and the windshield 1 are further improved.

[0031] Among them, referring to Figure 4 the fastener 5 shown, the fastener 5 includes a connecting plate 501, a second fastening hole 502 penetrating through the connecting plate 501 and communicating with the first fastening hole 103, a baffle 503 provided on one side of the bottom of the connecting plate 501 and extending along the height direction of the windshield 1, a docking post 504 adapted to the docking groove 102 provided on the inner end face of the baffle 503, side plates 505 symmetrically formed by inwards folding both sides of the baffle 503, and a guiding groove 506 for clamping the guiding strip 203 provided on the inner end face of the side plate 505. Through the setting of the fastener 5, the overall strength of the windshield 1 is ensured, and at the same time, the corners of the display board 2 can be protected from being knocked and damaged.

[0032] Furthermore, the connecting plate 501, the baffle 503, the docking post 504 and the side plate 505 are all made of aluminum profile structures.

[0033] During the installation of this embodiment, first, the advertising picture is pasted on the display board 2. Next, the end of the display board 2 provided with the clamping plate 201 is inserted into the installation groove 101, so that the guiding strip 204 on the display board 2 is inserted into the guiding groove 105 in the installation groove 101. When the guiding strip 204 is inserted to the bottom of the guiding groove 105, the clamping plate 201 on the display board 2 is inserted into the clamping groove accordingly, so that the first connection hole 202 on the clamping plate 201 communicates with the second connection hole 104 on the windshield 1. The connecting bolt 3 is inserted into the communicated first connection hole 202 and second connection hole 104 for fixation. Finally, the docking post 504 on the fastener 5 is aligned with the docking groove 102 on the windshield 1 for insertion, so that the guiding strip 203 on the display board 2 is inserted into the guiding groove 506 on the side plate 505 accordingly. When the guiding strip 203 is inserted to the bottom of the guiding groove 506, the second fastening hole 502 on the fastener 5 communicates with the first fastening hole 103 on the windshield 1. The fastening bolt 4 is inserted into the communicated first fastening hole 103 and second fastening hole 502 for fixation.

[0034] The setting of the windshield 1 die-cast from aluminum alloy material improves the overall strength and service life of the windshield 1. The setting of the transparent display board 2 made of reinforced plastic enables better display of the advertising pictures placed on the display board 2, improving the applicability. At the same time, the detachable connection between the display board 2 and the windshield 1 facilitates the staff to replace the advertising pictures. The setting of the armrest assembly 7 enables passengers standing at the door area to have something to hold when the passenger flow is large, avoiding safety accidents caused by passengers pushing and shoving each other when the vehicle brakes suddenly, thus improving the safety
