Technical Field

The utility model relates to the technical field of vehicles, in particular to a cab and a vehicle.

Background technique

As people's living standards improve, more and more people choose to travel in RVs. Traditional RVs are of two types: Type B and Type C. This type of RV is limited in space and carrying capacity. Therefore, light truck RVs with stronger carrying capacity, larger internal space, more layout styles and greater expandability are gradually becoming popular.

The rear panel of the cab of a light truck is connected to other panels of the cab to define the space of the cab. In order to facilitate the subsequent conversion of the light truck into a motorhome, it is necessary to open an installation opening connecting the cab and the car body on the rear panel of the cab of the light truck to meet the needs of the cab personnel to enter and exit the car body through the installation opening. Before the conversion, a light-transmitting plate, such as glass, can be installed at the installation opening to separate the cab and the car body. When the conversion is required, the light-transmitting plate can be removed to connect the cab and the car body.

However, the rear panel of a light truck cab is usually a roughly curved structure, rather than a flat plate. There is usually a mounting hole for installing a light-transmitting plate on the rear panel, and the side edge of the light-transmitting plate is bonded to the edge of the mounting hole. Since the side edge of the mounting hole is a curved surface that conforms to the shape, the side edge of the light-transmitting plate must also be designed as a curved surface that conforms to the shape, that is, the light-transmitting plate needs to be developed separately so that it can be adapted and installed on the rear panel. As a result, the development cycle of the light-transmitting plate is long and the development cost is high.

Please refer to Figures 1 to 4. The utility model proposes a cab, which is applied to a vehicle. A passenger compartment is arranged in the cab, and the cab includes a rear panel 100, a frame bracket 200 and a light-transmitting plate 300. The rear panel 100 is provided with a mounting opening 110, and the mounting opening 110 can connect the passenger compartment and the outer space of the cab; the frame bracket 200 is arranged at the mounting opening 110, and the frame bracket 200 encloses an avoidance opening 210 connected to the mounting opening 110, and the avoidance opening 210 and the mounting opening 110 are jointly configured to form a passage, and the passage can allow passengers to pass through. A mounting plane 220 is provided on the end surface of the frame bracket 200; the light-transmitting plate 300 is arranged on the mounting plane 220 and covers the passage.

Specifically, the cab is applied to vehicles, including but not limited to cars, trucks and public transportation. A passenger compartment is provided in the cab, in which the occupants can sit in the driver's seat. The passenger compartment generally includes seats, a console and other related equipment to support the normal operation of the vehicle. A rear panel 100 is provided at the rear of the cab, and a mounting opening 110 is provided on the rear panel 100. The mounting opening 110 is generally located in the middle of the rear panel 100, and can also be close to the right or left side of the rear panel 100 according to user needs. The mounting opening 110 can connect the outer space of the passenger compartment and the cab. The outer space refers to the external space outside the cab. When the light truck is converted into a motorhome, the outer space specifically refers to the cabin of the light truck. Specifically, for different vehicles, the compartment can be open, with the installation port 110 directly connected to the compartment; the compartment can also be closed, with an opening connected to the installation port 110, and the opening of the compartment forming a partial passage; the compartment can also be semi-closed, that is, the compartment and the cab are separated into two spaces by the rear panel 100, and connected through the installation port 110.

The frame bracket 200 is arranged around the mounting opening 110. The frame bracket 200 can be arranged on one side of the mounting opening 110 close to the passenger compartment, or on the other side of the mounting opening 110 away from the passenger compartment, or the inner wall of the mounting opening 110 can be abutted against the side wall of the frame bracket 200. The frame bracket 200 has a avoidance opening 210, and the avoidance opening 210 and the mounting opening 110 together constitute a man-passing passage, which can be passed by passengers to enable passengers to pass between the passenger compartment and the outer space. At least one end face of the outer side wall of the frame bracket 200 is a mounting plane 220 for installing the light-transmitting plate 300, and the light-transmitting plate 300 is installed on the mounting plane 220 to cover the man-passing passage. The light-transmitting plate 300 can be transparent or translucent to provide sufficient light and help maintain visual connectivity in the passenger compartment. The light-transmitting plate 300 can be a plastic that can transmit light, or glass, etc.

The mounting plane 220 of the frame bracket 200 can be directly installed for ordinary flat light-transmitting panels on the market. The flat light-transmitting panels 300 with large stocks on the market can be directly purchased. There is no need to specifically design the light-transmitting panels 300 according to the shape of the side edges of the mounting opening 110, which saves the development cycle of the light-transmitting panels 300 and reduces the development cost and manufacturing cost of the light-transmitting panels 300.

In addition, since the installation opening 110 of the rear panel 100 is part of the man-passing passage, passengers can pass through. Therefore, when the light truck is subsequently converted into a motorhome, the light-transmitting plate 300 can be directly removed to connect the passenger compartment with the outer space of the cab to meet the needs of passengers passing through the passenger compartment and the compartment, without the need to reconstruct the rear panel 100, which greatly improves the convenience and efficiency of converting a truck into a motorhome.

In one embodiment, the frame bracket 200 is disposed on a side of the mounting opening 110 close to the passenger compartment.

Please refer to FIG. 1 and FIG. 4 . The outer surface of the rear panel 100 is a curved surface that bulges toward the outer space. The space enclosed by the inner surface of the rear panel 100 forms part of the passenger compartment. The frame bracket 200 is arranged in the passenger compartment and on the inner surface of the rear panel 100. On the one hand, it can save the space required for installing the frame bracket 200. On the other hand, it can prevent the frame bracket 200 from being hit by the outside when it is arranged on the outer surface of the rear panel 100. In addition, the frame bracket 200 is arranged on the side of the installation opening 110 close to the passenger compartment, making the outer surface of the rear panel 100 smoother and more beautiful.

In one embodiment, the light-transmitting plate 300 is disposed on a side of the frame support 200 away from the passenger compartment.

Please refer to Figures 1 and 4. The light-transmitting plate 300 is installed on the rear panel 100 through the frame bracket 200, and covers the manhole to provide sufficient light. The light-transmitting plate 300 can be arranged on the side of the frame bracket 200 close to the passenger compartment, that is, the light-transmitting plate 300 is arranged in the passenger compartment; it can also be arranged on the side of the frame bracket 200 away from the passenger compartment, that is, the light-transmitting plate 300 is arranged outside the passenger compartment; it can also be arranged at the avoidance 210 and connected to the inner peripheral wall of the avoidance 210. The light-transmitting plate 300 is arranged on the side of the frame bracket 200 away from the passenger compartment, and the connection area between the light-transmitting plate 300 and the frame bracket 200 is larger, and the connection is more stable. When the light-transmitting plate 300 is subjected to a force perpendicular to the plane where the light-transmitting plate 300 is located, it is not easy to separate from the frame bracket 200. The frame bracket 200 is arranged on the side of the installation opening 110 close to the passenger compartment, and the light-transmitting plate 300 is arranged on the side of the frame bracket 200 away from the passenger compartment. The installation structure of the rear panel 100, the frame bracket 200 and the light-transmitting plate 300 is compact and occupies little space.

In one embodiment, the edge of the installation opening 110 extends toward the light-transmitting plate 300 and is disposed adjacent to the peripheral side surface of the light-transmitting plate 300 .

Please refer to FIG. 4 . The rear panel 100 is generally made of sheet metal, and the edge of its mounting opening 110 is generally sharp and easy to cut others. The edge of the mounting opening 110 extends toward the light-transmitting plate 300 to prevent the edge of the mounting opening 110 from tilting toward the outer space, thereby reducing the risk of cutting others and reducing the risk of the edge of the mounting opening 110 being hit by the outside. In other embodiments, the edge of the mounting opening 110 may also extend toward the frame bracket 200. In order to further reduce the risk of the edge of the mounting opening 110 cutting others, the edge of the mounting opening 110 extends toward the light-transmitting plate 300 and is disposed adjacent to the peripheral side of the light-transmitting plate 300 to reduce the distance between the edge of the mounting opening 110 and the light-transmitting plate 300, thereby preventing the gap between the edge of the mounting opening 110 and the light-transmitting plate 300 from being too large, and preventing the hand from being cut by the edge of the mounting opening 110 when the hand is inserted into the gap.

In one embodiment, in the front-rear direction of the cab, the installation opening 110 is located at the front side of the rear end surface of the light-transmitting plate 300 , or the installation opening 110 is flush with the rear end surface of the light-transmitting plate 300 .

Referring to FIG. 4 , the mounting opening 110 is located at the front side of the rear end surface of the light-transmitting plate 300, or the mounting opening 110 is flush with the rear end surface of the light-transmitting plate 300, that is, the edge of the mounting opening 110 does not exceed the outer surface of the light-transmitting plate 300, so as to avoid the edge of the mounting opening 110 being exposed to the outside of the light-transmitting plate 300, thereby reducing the risk of the edge of the mounting opening 110 cutting others. At the same time, the edge of the mounting opening 110 does not exceed the outer surface of the light-transmitting plate 300, so as to avoid the edge of the mounting opening 110 blocking the installation area of the light-transmitting plate 300, thereby improving the convenience of installing the light-transmitting plate 300.

In one embodiment, a projection contour of the edge of the mounting opening 110 in a direction perpendicular to the mounting plane 220 falls within the mounting plane 220 .

Referring to FIG. 4 , when the projection contour of the edge of the mounting opening 110 in the direction perpendicular to the mounting plane 220 falls outside the outer periphery of the mounting plane 220, there is a gap between the edge of the mounting opening 110 and the frame bracket 200 in the left-right direction, which is not conducive to the stability of the connection between the frame bracket 200 and the rear panel 100, and on the other hand, the passenger compartment is connected to the outer space through the gap, which is not conducive to the sealing inside the passenger compartment, and rainwater, dust, etc. in the outer space easily enter the passenger compartment through the gap. When the projection contour of the edge of the mounting opening 110 in the direction perpendicular to the mounting plane 220 falls inside the inner periphery of the mounting plane 220, the edge of the mounting opening 110 blocks the installation area of the light-transmitting plate 300, increasing the difficulty of installing the light-transmitting plate 300, or causing the rear panel 100 and the light-transmitting plate 300 to be arranged on opposite sides of the frame bracket 200, which is not conducive to the compactness of the installation structure of the rear panel 100, the frame bracket 200 and the light-transmitting plate 300. In addition, the edge of the installation opening 110 is exposed in the avoidance opening 210, which may easily cut others. Therefore, the projection contour of the edge of the installation opening 110 in the direction perpendicular to the installation plane 220 falls into the installation plane 220, which can ensure the sealing of the interior of the passenger compartment and improve the safety of the cab.

In one embodiment, the cab also includes a connecting bracket 400, which is arranged on a side of the frame bracket 200 away from the avoidance opening 210. The connecting bracket 400 includes an intersecting first connecting portion 410 and a second connecting portion 420.

The connecting bracket 400 includes an intersecting first connecting portion 410 and a second connecting portion 420. The first connecting portion 410 is firmly connected to the frame bracket 200 by welding or bonding. The connecting surface between the frame bracket 200 and the first connecting portion 410 is not only flat, but also has a large area, which ensures a stable connection between the connecting bracket 400 and the frame bracket 200. The second connecting portion 420 and the first connecting portion 410 can be connected by welding, screw fastening, etc., or can be integrally formed. The second connection portion 420 is connected to the side of the rear panel 100 close to the passenger compartment. The second connection portion 420 has a simple shape and a small volume, and is easily fixedly connected to the rear panel 100. The first connection portion 410 and the second connection portion 420 are generally "L"-shaped, and the angle formed by the first connection portion 410 and the second connection portion 420 can be an acute angle, a right angle, or an obtuse angle.
