[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0035] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0037] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0038] This embodiment provides a vehicle, which includes a door assembly, see Figure 1 and Figure 2The door assembly includes a door body 1, on which a first window 11 and a second window 12 are arranged. The second window 12 is located below the first window 11. The first window 11 and the second window 12 are respectively provided with a first glass 13 and a second glass 14. The first glass 13 is a vehicle window glass, and the second glass 14 is an observation window glass. The driver can observe the situation outside the vehicle through the second glass 14, thereby improving driving safety.

[0039] In this embodiment, the second glass 14 includes a first glass layer 141 and a second glass layer 142. The first glass layer 141 and the second glass layer 142 are respectively installed on both sides of the door body 1. In this embodiment, the sound insulation and heat insulation performance of the cab can be improved by setting two glass layers.

[0040] On the other hand, the cleanliness of the second glass 14 has an important influence on whether the driver can clearly observe the situation outside the vehicle. In other words, if there are a lot of stains or dust on the second glass 14, the driver will not be able to clearly observe the situation outside the vehicle. For this reason, the driver needs to clean the second glass 14 frequently. In addition to cleaning the side of the first glass layer 141 away from the second glass layer 142 and the side of the second glass layer 142 away from the first glass layer 141, the driver also needs to clean the side of the first glass layer 141 facing the second glass layer 142 and the side of the second glass layer 142 facing the first glass layer 141. If the first glass layer 141 and the second glass layer 142 are both fixedly installed on the vehicle door body 1, the driver needs to remove the first glass layer 141 or the second glass layer 142 from the vehicle door body 1 before cleaning the side of the first glass layer 141 facing the second glass layer 142 and the side of the second glass layer 142 facing the first glass layer 141. The whole process is time-consuming and laborious. In order to solve the above problem, Figure 1 , Figure 2 as well as Figures 5 to 7 As shown, the door assembly in this embodiment also includes a hinge 2 and a lock 3. The second glass layer 142 is hinged to the door body 1 through the hinge 2. The lock 3 includes a fixed portion 31 and a movable portion 32. The fixed portion 31 and the movable portion 32 are respectively fixedly connected to the door body 1 and the second glass layer 142. The movable portion 32 has a first working state in which it is locked to the fixed portion 31 and a second working state in which it is released from the fixed portion 31. In this embodiment, the driver only needs to switch the movable portion 32 from the first working state to the second working state to rotate the second glass layer 142 around the hinge 2, so as to directly clean the side of the first glass layer 141 facing the second glass layer 142 and the side of the second glass layer 142 facing the first glass layer 141. After cleaning, the driver only needs to rotate the second glass layer 142 around the hinge 2 to reset it, and switch the movable portion 32 from the second working state to the first working state. The whole process saves time and effort.

[0041] Based on the above, the movable portion 32 in this embodiment includes a mounting frame 321 and a rotating frame 322. The mounting frame 321 is fixedly connected to the second glass layer 142, and the mounting frame 321 is provided with a limit block 3211. The rotating frame 322 is rotatably connected to the mounting frame 321 through a rotating shaft 323. The rotating frame 322 and the fixed portion 31 are respectively provided with a first abutment plate 3221 and a second abutment plate 311. The first abutment plate 3221 has a side facing the door body 1 with the second abutment plate 311. The first working position of the first abutment plate 3221 and the second working position of the first abutment plate 3221 rotating about the rotating shaft 323 and away from the second abutment plate 311, the rotating shaft 323 is provided with a torsion spring 324, and the two torsion arms 3241 of the torsion spring 324 are respectively in contact with the first abutment plate 3221 and the limit block 3211. When the first abutment plate 3221 is located in the second working position, the torsion spring 324 can be elastically deformed and has elastic potential energy to restore the first abutment plate 3221 to the first working position. In this embodiment, the rotating shaft 323 is provided with a torsion spring 324, and the two torsion arms 3241 of the torsion spring 324 are respectively in contact with the first abutment plate 3221 and the limit block 3211. The side of the frame 322 away from the first abutment plate 3221 is the power end, and the first abutment plate 3221 and the power end are respectively located on both sides of the rotating shaft 323. The driver can apply force to the power end to rotate the first abutment plate 3221 from the first working position to the second working position. When the first abutment plate 3221 rotates to the second working position, the driver can offset the force applied by the torsion spring 324 to the first abutment plate 3221 by continuously applying force to the power end of the first abutment plate 3221, thereby keeping the first abutment plate 3221 in the second working position, and the second abutment plate 311 and the first abutment plate 3221 located in the second working position are misaligned, that is, the second abutment plate 311 is not located on the path of the first abutment plate 3221 rotating around the hinge 2. Therefore, the driver can rotate the second glass layer 142 around the hinge 2, so as to directly clean the side of the first glass layer 141 facing the second glass layer 142 and the side of the second glass layer 142 facing the first glass layer 141.

[0042] When cleaning is completed, the driver still keeps the first abutment plate 3221 in the second working position, and at the same time rotates the second glass layer 142 around the hinge 2 to reset. When the second glass layer 142 is reset, the driver cancels the force applied to the power end of the first abutment plate 3221, the torsion spring 324 recovers its deformation, and the first abutment plate 3221 is restored from the second working position to the first working position, and the first abutment plate 3221 is again abutted against the side of the second abutment plate 311 toward the door body 1, that is, the movable part 32 is re-locked to the fixed part 31, and the driver can continue to observe the situation outside the vehicle through the second glass 14.

[0043] See also Figure 1The vehicle door body 1 in this embodiment includes a vehicle door outer panel 16 and a vehicle door inner panel, the vehicle door inner panel is fixedly connected to the vehicle door outer panel 16, the first glass layer 141 is installed on the side of the vehicle door outer panel 16 away from the vehicle door inner panel, and the second glass layer 142 is installed on the side of the vehicle door inner panel away from the vehicle door outer panel 16, so that the first glass layer 141 and the second glass layer 142 are respectively installed on both sides of the vehicle door body 1.

[0044] Preferably, the door inner panel includes a first plate portion 151 and a second plate portion 152, the first plate portion 151 is fixedly connected to the door outer panel 16, the second plate portion 152 is fixedly connected to the first plate portion 151, a cavity is formed between the first plate portion 151 and the second plate portion 152, at least two guide rails 6 extending in the vertical direction are installed in the cavity, at least two guide rails 6 are arranged at intervals in the horizontal direction, the first glass 13 is slidably connected to the at least two guide rails 6, and the first glass 13 can be raised and lowered along all the guide rails 6 to ensure the ventilation effect of the cab in summer, and at the same time, it is convenient for the driver to clean the rearview mirror. It can be understood that since the first glass 13 is slidably connected to the at least two guide rails 6 at the same time, the stability of the first glass 13 in the vertical direction is relatively high.

[0045] It can be understood that the sliding structure between the first glass 13 and the guide rail 6 and the structure of the guide rail 6 belong to the prior art and will not be described in detail in this embodiment.

[0046] Furthermore, the second plate portion 152 mentioned above provides an installation position for functional components such as a speaker (not shown in the figure). Exemplarily, a speaker bracket (not shown in the figure) is welded to the second plate portion 152, and the speaker bracket is used to fix the speaker.

[0047] In this embodiment, the first glass layer 141 is preferably bonded to the side of the door outer panel 16 away from the door inner panel. Specifically, a polyurethane adhesive layer 17 is coated on the edge of the first glass layer 141 facing the second glass layer 142 to bond to the side of the door outer panel 16 away from the door inner panel.

[0048] Based on the above, the door assembly in this embodiment also includes an interior trim panel 4, which is fixedly connected to the door body 1 and covered on the side of the door inner panel away from the door outer panel 16 to ensure the aesthetics of the interior of the cab. A first through hole 41 is provided on the interior trim panel 4, and a second through hole (not shown in the figure) and a third through hole are respectively provided on the door outer panel 16 and the door inner panel. The second through hole and the third through hole together form a second window 12. The first through hole 41 is opposite to the second window 12. The edge of the first glass layer 141 on one side facing the second glass layer 142 is bonded to a position on the door outer panel 16 near the second through hole through a polyurethane adhesive layer 17. The driver can observe the situation outside the vehicle through the second glass 14 and the first through hole 41.

[0049] like Figures 1 to 4 As shown, the door assembly in this embodiment also includes a sealing ring 5, which is clamped on the interior panel 4. Specifically, the sealing ring 5 includes a clamping portion 51 and a pressing portion 52. The clamping portion 51 and the pressing portion 52 are both annular rings. The clamping portion 51 is hollow and is provided with an opening (not shown in the figure). The opening is connected to the internal space of the clamping portion 51. The first plate portion 151 and the second plate portion 152 are respectively provided with a fourth through hole (not shown in the figure) and a fifth through hole 1521. The fourth The through hole and the fifth through hole 1521 together form a third through hole, and a position on the second plate portion 152 close to the fifth through hole 1521 and a position on the interior trim panel 4 close to the first through hole 41 both extend from the opening into the interior of the clamping portion 51, and the second plate portion 152 and the interior trim panel 4 are pressed between the portions located on both sides of the opening. When the movable portion 32 is in the first working state, the pressing portion 52 of the sealing ring 5 is pressed between the edge of the second glass layer 142 and a position on the interior trim panel 4 close to the first through hole 41.

[0050] Preferably, a positioning block 1411 is provided at the edge of the first glass layer 141 in the present embodiment, and the side of the door outer panel 16 away from the door inner panel and the hole wall of the second through hole are both in contact with the positioning block 1411. In the present embodiment, the thickness of the positioning block 1411 abutting between the side of the door outer panel 16 away from the door inner panel and the first glass layer 141 can be controlled to ensure that the surface difference between the first glass layer 141 and the door outer panel 16 meets the requirements. Since the hole wall of the second through hole abuts against the positioning block 1411, that is, the position of the positioning block 1411 relative to the door outer panel 16 is fixed, the present embodiment can control the gap between the first glass layer 141 and the door outer panel 16 by controlling the relative position of the first glass layer 141 and the positioning block 1411.

[0051] Furthermore, in order to improve the overall strength and rigidity of the door assembly, the position near the third through hole on the door inner panel in this embodiment is welded to the position near the second through hole on the door outer panel 16. Specifically, in this embodiment, the overall strength and rigidity of the door assembly are improved by welding the position near the fourth through hole on the first plate portion 151 to the position near the second through hole on the door outer panel 16.
