Technical Field

[0001] The utility model relates to the technical field of automobile safe driving, in particular to a cab protection device for automobile safe driving. Background Art

[0002] Cars are a common means of transportation in people's daily lives, and the most common of them are buses. Existing buses usually have protective doors installed on the cab to separate the driver's driving position from the passenger seat to prevent passengers from grabbing the steering wheel while the vehicle is driving or causing personal injury to the driver. These two methods greatly affect the safe driving of the vehicle and threaten the lives of passengers. Effectively isolating the driver is the best way to protect him.

[0003] After searching, the Chinese patent "A cab protection device for safe driving of automobiles" authorization announcement number "CN214823132U" realizes the impact and smashing of tempered glass through internal buttons, external buttons, a crushing box, an impact block and a first spring, thereby improving the safety of the protection device and ensuring the personal safety of the driver.

[0004] In the above-mentioned method of smashing the tempered glass by the impact block, since the space in the cab is small, the broken tempered glass is easily splashed onto the driver during the smashing process, thereby reducing the safety protection for the driver.

[0005] Therefore, a cab protection device for safe driving of an automobile is proposed to solve the above problems. Utility Model Content

[0024] When implementing: Figure 1-4 As shown, a cab protection device for safe driving of an automobile comprises: a cab base 1, a protective plate 2 is fixedly connected to the top of the cab base 1, a protective door frame 3 is hinged to one side of the protective plate 2, a fixed rod 4 is fixedly connected to the top of the cab base 1, an external button 5 is fixedly connected to the front end of the protective plate 2, and an internal button 6 is fixedly connected to the upper end of one side of the protective plate 2; a protective mechanism 7, the protective mechanism 7 is arranged at the rear end of the protective door frame 3; wherein the protective mechanism 7 comprises a fixed block 71 fixedly connected to the surface of the fixed rod 4, a counterweight rod 72 is slidably connected to the rear end of the protective door frame 3, and the lower end of the surface of the counterweight rod 72 is clamped to the inner side of the fixed block 71, an electric telescopic rod 73 is fixedly connected to the top of the cab base 1, a ball 710 is rollingly connected to the lower end of the surface of the protective door frame 3, and the surface of the ball 710 is rollingly connected to the top of the cab base 1, and a baffle 8 is fixedly connected to the top of the cab base 1, and one side of the baffle 8 is fixedly connected to the surface of the fixed rod 4. The surfaces of the protective door frame 3 and the protective plate 2 are both embedded with tempered glass.

[0025] When driving a bus, the driver pulls the protective door frame 3 so that one side of the protective door frame 3 contacts the fixed rod 4, pushes the counterweight rod 72 downward, and makes the counterweight rod 72 engage in the fixed block 71, so that the protective door frame 3 is locked on the fixed rod 4. At this time, the protective plate 2, the protective door frame 3, the fixed rod 4 and the baffle 8 surround the driver, preventing the passengers and the driver from snatching the steering wheel, thereby ensuring the safety of the driver and passengers on the bus.

[0026] When the driver is unconscious in the cab, the passenger presses the external button 5 to energize the electric telescopic rod 73, and the telescopic end of the electric telescopic rod 73 moves upward to push the counterweight rod 72 upward, so that the counterweight rod 72 is away from the fixed block 71. At this time, the electric telescopic rod 73 stops moving upward and remains motionless, releasing the lock of the protective door frame 3 on the fixed rod 4. At this time, the passenger pulls the protective door frame 3 to open the cab door, and the passenger rescues the driver safely. Later, the external button 5 or the internal button 6 is pressed to energize the electric telescopic rod 73, and the telescopic end of the electric telescopic rod 73 moves downward to reset, so that the counterweight rod 72 can lock the protective door frame 3 on the fixed block 71.

[0027] like Figure 3As shown, the upper end of the surface of the fixed rod 4 is fixedly connected to a push cylinder 74, the inner wall of the push cylinder 74 is slidably connected to a push rod 75, the push rod 75 and the opposite end of the push cylinder 74 are fixedly connected to a spring 76, the inner wall of the push cylinder 74 is slidably connected to a limit rod 77, the surface of the limit rod 77 is clamped on the inner wall of the push rod 75, the upper end of the surface of the limit rod 77 is fixedly connected to a connecting frame 78, the rear end of the connecting frame 78 is fixedly connected to the telescopic end of the electric telescopic rod 73, one end of the push rod 75 is fixedly connected to a sliding rod 79, one end of the sliding rod 79 passes through and extends out of the inner wall of the push cylinder 74.

[0028] The telescopic end of the electric telescopic rod 73 moves upward, driving the connecting frame 78 and the limit rod 77 to move upward, and the limit rod 77 moves upward away from the push rod 75. At this time, the elastic force of the spring 76 pushes the push rod 75 to move, and the movement of the push rod 75 pushes the protective door frame 3 to move, causing the ball 710 to roll on the cab base 1 to open the cab.

[0029] like Figure 4 As shown, the upper and lower ends of the surface of the protective plate 2 are fixedly connected with protective tubes 711, the surface of the external button 5 is located on the inner side of one of the protective tubes 711, and the surface of the internal button 6 is located on the inner side of the other side of the protective tube 711. The surface of the protective tube 711 is threadedly connected with a protective cover 712, and transparent glass is embedded on the inner side of the protective cover 712.

[0030] The protective tube 711 and the protective cover 712 surround and protect the external button 5 and the internal button 6 to prevent passengers or drivers from accidentally touching the external button 5 or the internal button 6. When the driver is driving, the passenger has to grab the steering wheel with the driver, squat down and turn the protective cover 712 to press the external button 5. During this period of time, the driver or other passengers can make emergency responses in time to ensure the life safety of the driver and passengers on the bus.

[0031] When the utility model is in use, the driver becomes unconscious in the cab, and the passenger rotates one of the protective covers 712 to make one of the protective covers 712 move away from one of the protective tubes 711. At this time, the external button 5 is pressed to energize the electric telescopic rod 73, and the telescopic end of the electric telescopic rod 73 moves up to push the counterweight rod 72, the connecting frame 78 and the limit rod 77 to move up, so that the counterweight rod 72 is away from the fixed block 71, and the limit rod 77 moves up and away from the push rod 75. At this time, the elastic force of the spring 76 pushes the push rod 75 to move, and the push rod 75 moves to push the protective door frame 3 to move, so that the ball 710 rolls on the cab base 1 to open the cab. At this time, the electric telescopic rod 73 stops moving up and remains motionless, releasing the lock of the protective door frame 3 on the fixed rod 4. At this time, the passenger pulls the protective door frame 3 to open the cab door, and the passenger rescues the driver safely. Later, the external button 5 or the internal button 6 is pressed to energize the electric telescopic rod 73 , and the telescopic end of the electric telescopic rod 73 moves downward to reset, so that the counterweight rod 72 can lock the protective door frame 3 on the fixed block 71 .
