Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cabs, in particular to a laminated glass frame cab assembly. Background Art
[0002] The cab assembly refers to the entire cab, including the basic structural components such as the frame and exterior casing. The exterior casing protects the driver from the external environment. It also includes interior components such as the seats, instrument panel, and steering wheel, which provide a comfortable operating environment and easy access to vehicle status. Furthermore, it includes related electrical systems such as interior lighting and various indicator lights. In some vehicles, the cab assembly also includes comfort features such as the air conditioning system.
[0003] In the prior art, when a fire occurs in the cab, the driver needs to leave the cab immediately to ensure personal safety. This may result in the driver being unable to take and use a fire extinguisher to put out the fire in time, causing great economic losses and low safety and convenience.
[0004] The basic structure of the entire cab consists of glass mounted on a cab frame, providing the necessary support and ensuring a secure installation on the harvester. This frame protects the internal equipment from external impact and damage, while also providing a degree of safety for the driver. However, current agricultural machinery glass is typically cut from a single sheet of glass, which has poor impact resistance and easily breaks completely when struck by stones or thick branches. Such impacts can injure occupants, not to mention the potential for shattered glass fragments to injure the operator, rendering it ineffective in protecting the operator. Utility Model Content
[0005] The utility model discloses a cab assembly laminated glass and frame, which aims to solve the problem that when a fire occurs in the cab, the driver may not be able to take out and use a fire extinguisher in time to put out the fire before leaving the cab, and further solve the problem that the cab has insufficient violence strength and is easy to be injured by the driver when hit by foreign objects.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] A laminated glass frame cab assembly includes a frame body, characterized in that an automatic fire extinguishing module is provided on the frame body, and the automatic fire extinguishing module includes a storage box, which is fixedly connected to the top of the frame body; a mounting hole one is opened on the frame body, and a shock-absorbing fixing module is provided on the frame body, and the shock-absorbing fixing module includes a mounting frame, which is fixedly connected in the mounting hole one; a laminated glass body is mounted on the frame body, and the laminated glass body includes two pieces of tempered glass and an organic polymer intermediate film, and the laminated glass body has an arc-shaped convex surface convex outward.
[0008] In a preferred embodiment, the double-arc surface of the laminated glass body is composed of two arcs with different radii. The radius of the arc surface on the vertical section of the laminated glass body gradually increases from the center to the periphery, and the radius of the arc surface on the horizontal section of the laminated glass body gradually increases from the center to the periphery.
[0009] In a preferred embodiment, the arc radius on the vertical cross-section of the laminated glass body is 5500-6500mm, and the arc length is 1350-1550mm; the arc radius on the horizontal cross-section of the laminated glass body is 2000-3000mm, and the arc length is 1650-1950mm. Double-curved laminated glass, particularly the combination of this radius and arc, allows the double-sided laminated glass to achieve an optimal viewing angle while also being highly resistant to damage. This is particularly true when struck by unexpected foreign objects such as tree branches, not only providing excellent puncture resistance but also mitigating damage. Furthermore, it prevents glass from breaking into shattered fragments and causing injury after punctures and impacts, significantly enhancing the safety of those in the cab.
[0010] A cab assembly laminated glass comprises a laminated glass body, wherein the laminated glass body comprises two pieces of tempered glass and an organic polymer intermediate film.
[0011] A cab assembly frame comprises a frame body, an automatic fire extinguishing module is provided on the frame body, and the automatic fire extinguishing module comprises a storage box, the storage box is fixedly connected to the top of the frame body, a mounting hole 1 is provided on the frame body, and a shock-absorbing fixing module is provided on the frame body, the shock-absorbing fixing module comprises a mounting frame, the mounting frame is fixedly connected to the mounting hole 1, a pump is fixedly connected to the top of the frame body, and a circular hole 1 is provided on one side of the storage box, the input end of the pump is fixedly connected to the circular hole 1, the output end of the pump is fixedly connected to the discharge pipe, and a circular hole 2 is provided on the top of the frame body. The top inner wall of the frame body is fixedly connected to a sliding frame, the outer wall of the sliding frame is slidably connected to a sliding member, the bottom of the sliding member is fixedly connected to a discharge bin, a plurality of circular holes three are equidistantly provided at the bottom of the discharge bin, and nozzles are fixedly connected to the plurality of circular holes three, a circular hole four is provided on one side of the discharge bin, the end of the discharge pipe away from the pump passes through the circular hole two and is fixedly connected to the circular hole four, a circular hole five is provided on the sliding member, a rotating shaft is movably connected to the circular hole five, the top of the sliding member is fixedly connected to the motor, the output end of the motor is fixedly connected to the rotating shaft, the outer wall of the rotating shaft is fixedly connected to a runner, and the runner is in close contact with the sliding frame.
[0012] By providing an automatic fire extinguishing module, when a fire occurs in the cab, the fire extinguishing agent in the storage box is pumped into the discharge bin through the discharge pipe by a pump and sprayed out through a nozzle to extinguish the fire. At the same time, the motor rotates the shaft and the wheel to drive the sliding part and the discharge bin to move, so that the fire extinguishing agent is evenly sprayed in the cab, improving the fire extinguishing effect. It can automatically extinguish the fire, avoiding the need for the driver to use a fire extinguisher to extinguish the fire by himself, ensuring personal safety and reducing losses, and improving safety and convenience.
[0013] In a preferred solution, the inner walls on both sides of the opposite sides of the mounting frame are fixedly connected to sliding rail parts, and the two sliding rail parts are provided with a circular hole six, and the two circular holes six are fixedly connected to a limit rod, and the outer walls of the two limit rods are slidably connected to two sliding blocks, and a circular hole seven is provided on multiple sliding blocks, and thin rods are fixedly connected in the multiple circular holes seven, and the outer walls of the multiple thin rods are movably connected to a support rod, and the two support rods on the same side are movably connected to the same fixed seat at one end away from the sliding block, and springs are surrounded by the outside of the two ends of the two limit rods, and one end of the multiple springs is fixedly connected to the corresponding sliding rail parts, and the other ends of the multiple springs are fixedly connected to the corresponding sliding blocks, and two mounting holes two are provided on the frame body, and side doors are connected to the two mounting holes two by hinges, and a handle is fixedly connected to one side of the two side doors.
[0014] By providing a shock-absorbing fixing module, when encountering a large bump during driving, the laminated glass body drives the fixing seat to move, pushes and pulls the support rod, and forces the sliding block to compress or stretch the spring to slide on the outer wall of the limit rod. The elastic action of the spring can reduce the vibration, avoiding the laminated glass body from being easily damaged when the vibration amplitude is large, as in the case of using a rigid connection, thereby improving practicality.
[0015] From the above, we can see the beneficial effects of this application. The laminated glass frame cab assembly provided by this utility model has the technical effect of being able to automatically extinguish the fire in the cab after a fire occurs, allowing the driver to evacuate first without having to use a fire extinguisher to extinguish the fire, ensuring personal safety and reducing losses, thereby improving safety and convenience. This application uses double-curved laminated glass, especially a combination of specific radius and curvature, which allows the double-sided laminated glass to achieve the best viewing angle while having extremely high damage resistance. Especially when accidentally hit by foreign objects such as branches, it can not only provide excellent anti-puncture resistance, but also reduce the damage caused by puncture, and can avoid the situation where the glass breaks into fragments and injures people after puncture and impact, greatly increasing the personal safety of people in the cab.
