DETAILED DESCRIPTION

[0030] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0031] Embodiment one, please refer to Figure 1 - Figure 6 In the utility model embodiment, a cab of mine car with ceiling air bag protection, including cab 100, the top of cab 100 is installed and fixed with ceiling 110, cab 100 inside is fixed with seat 120, the inner top surface of ceiling 110 is fixed with air bag 200 that can protect the head of driver, the top surface of ceiling 110 is fixed with steel bottle 300, steel bottle 300 and air bag 200 are fixed with the communication of air outlet pipe one 310, one end of air bag 200 is fixed with the communication of air outlet pipe two 320 that extends to the inside of cab 100, one end of ceiling 110 is rotatably connected with protective plate 400, protective plate 400 and ceiling 110 are fixed with multiple telescopic rods 410 at equal intervals, telescopic rod 410 includes arc cylinder 411 fixedly connected with ceiling 110, arc rod 412 is slidably connected in the inside of arc cylinder 411, arc spring 413 is fixed between arc rod 412 and arc cylinder 411.

[0032] Specifically, the falling rocks hitting the roof 110 of the cab 100 will first fall on the inclined protective plate 400, and the inclined protective plate 400 facilitates the rocks to roll away from the cab 100 quickly, which is beneficial to protect the cab 100. The gas bag 200 is fixed on the inner top surface of the roof 110 of the cab 100, and the steel cylinder 300 containing high-pressure oxygen is fixed on the top surface of the roof 110. When the cab 100 is overturned or pressed by the falling rocks, the steel cylinder 300 supplies gas to the gas bag 200 through the gas outlet pipe 310, and the inflated gas bag 200 is beneficial to protect the driver's head, which further improves the safety of the cab 100.

[0033] As shown in Figure 2 and Figure 3 in the embodiment, the top of the roof 110 is fixed with a support seat 111, and one end of the protective plate 400 is fixed with two rotating seats 420 which are rotatably connected with the support seats 111. The rotating seats 420 rotate between the two support seats 111 to enable the protective plate 400 to rotate stably on the top of the roof 110, and buffer the impact force of the falling rocks.

[0034] As shown in Figure 3 in the embodiment, the inner bottom surface of the arc-shaped cylinder 411 is fixed with a pressure sensor 414 between the arc-shaped spring 413 and the arc-shaped cylinder 411. When the falling rocks hit the protective plate 400, the protective plate 400 presses the arc-shaped spring 413 through the arc-shaped rod 412, and the compression elastic force of the arc-shaped spring 413 can buffer the impact force of the falling rocks. After the falling rocks slide along the inclined protective plate 400, the protective plate 400 rotates back to the initial position under the restoring force of the arc-shaped spring 413.

[0035] In the embodiment, the pressure sensor 414 is installed between the arc-shaped spring 413 and the inner bottom surface of the arc-shaped cylinder 411. When the falling rocks press on the protective plate 400, the protective plate 400 presses multiple arc-shaped rods 412 into the arc-shaped cylinder 411, so that the arc-shaped spring 413 is in a compressed state for a long time, and then the arc-shaped spring 413 presses the pressure sensor 414 for a long time. The existing technical components such as the controller and the gyroscope can be installed in the cab 100. When the controller receives that the pressure sensor 414 is in a compressed state for a long time, the controller can control the steel cylinder 300 to automatically supply gas to the gas bag 200 to protect the driver. The gyroscope can detect whether the cab 100 is overturned, and then transmit the overturning information of the cab 100 to the controller. The controller can again control the steel cylinder 300 to automatically supply gas to the gas bag 200. The controller controls the electromagnetic valve on the gas outlet pipe 310 of the steel cylinder 300, and the gyroscope detects the driving state of the cab 100, which are all existing technologies, and the control and working principles are not described in detail.

[0036] As shown in Figure 2 and Figure 4 , in this embodiment, one end of the second outlet pipe 320 is communicated and fixed with an outlet nozzle 321, and one end of the cylinder 300 is communicated and fixed with the filling pipe 330. When the cab 100 is in an oxygen-poor environment, the electromagnetic valve on the second outlet pipe 320 is opened to enable the oxygen inside the cylinder 300 to be delivered to the cab 100 through the second outlet pipe 320 and the outlet nozzle 321, achieving the effect of emergency oxygen supply.

[0037] As shown in Figure 4 , in this embodiment, electromagnetic valves are installed on the outside of the second outlet pipe 320, the first outlet pipe 310, and the filling pipe 330. The electromagnetic valves are used to control whether the pipes are connected or disconnected. The filling pipe 330 is used to supplement the standby oxygen in the cylinder 300.

[0038] In Embodiment Two, based on Embodiment One, in order to support and protect the driver's head when the cab 100 rolls over, the headrest 121 position of the seat 120 can be supported.

[0039] As shown in Figure 5 and Figure 6 , in this embodiment, the top of the seat 120 is fixed with a headrest 121. The outside of the headrest 121 is provided with a support assembly 500. The support assembly 500 includes two support blocks 510 fixed on the two sides of the headrest 121. One end of each support block 510 is provided with an arc-shaped cavity. A T-shaped pipe 520 is fixedly connected between the two support blocks 510. The T-shaped pipe 520 is in communication with the arc-shaped cavities. An active block 530 is slidingly connected inside the arc-shaped cavities. The inside of the active block 530 is provided with a circular hole in communication with the arc-shaped cavities. A soft pipe 210 is fixedly connected between the air bag 200 and the T-shaped pipe 520. An overflow valve 531 is fixedly installed inside the circular hole.

[0040] In this embodiment, when the air bag 200 is filled with gas, excessive gas will be delivered from the soft pipe 210 to the T-shaped pipe 520, and then to the arc-shaped cavities inside the two support blocks 510. Under the action of high gas pressure, the active block 530 will be pushed out of the arc-shaped cavities, and then the active block 530 with a rubber sleeve or a sponge sleeve fixedly connected to the outside will be supported on both sides of the driver's head. At the same time, when the high gas pressure in the arc-shaped cavities reaches a certain degree, it will overflow from the overflow valve 531 for the driver to breathe. Especially when the cab 100 rolls over and the driver lies on the seat 120, the active block 530 can support the driver's head from one side of the head, preventing the driver's head from being supported by the neck for a long time, causing secondary injury.

[0041] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application.
