Description

Technical Field

[0001] This utility model relates to the field of safe driving of tourist sightseeing vehicles, specifically to a probe reminder device for off-road tourist sightseeing vehicles. Background Technology

[0002] The safety of passengers inside a moving vehicle is always a major concern, and passengers extending their arms out of the vehicle is one of the main causes of safety problems. Off-highway tourist vehicles, with their open side panels, make it even easier for passengers to extend their arms out, thus posing a significant safety hazard.

[0003] Chinese utility model patent application number 201720699016.5 discloses a foreign object protrusion alarm circuit for vehicle windows. This circuit detects whether an object is protruding outside the window and promptly triggers an alarm when such an object is detected, thus alerting occupants and effectively preventing accidents. Because off-road tourist vehicles have open sides, passengers can more easily extend their arms out of the vehicle, making it easier for foreign objects such as leaves to enter. Therefore, if only the technical solution disclosed in the aforementioned patent is used, the entry of a foreign object into the vehicle might be mistaken for a passenger extending their arm out of the window, leading to false alarms and compromising safe driving. Utility Model Content

[0004] In summary, to address the shortcomings of existing technologies, the technical problem to be solved by this utility model is to provide a probe warning device for off-road tourist sightseeing vehicles.

[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0027] like Figure 1 and 3 As shown, a protrusion warning device for off-road tourist vehicles includes a monitoring device and an alarm device 1. The monitoring device is installed on both sides of the tourist vehicle 2 and can monitor and identify whether a passenger is protruding outside the vehicle or a foreign object is entering the vehicle. The alarm device 1 is installed on the tourist vehicle 2 and is electrically connected to the monitoring device, issuing an alert when the monitoring device detects a passenger protruding outside the vehicle. Preferably, the alarm device 1 is installed at the top center of the rear of the driver's cab on the tourist vehicle 2.

[0028] like Figure 2 , 4 As shown in Figure 5, the monitoring device includes a first infrared detector and a second infrared detector, which are installed side-by-side on the side of the sightseeing vehicle 2 along its width. Figure 6As shown, the first infrared detector is positioned relative to the second infrared detector on the outer side of the sightseeing vehicle 2, and both are vertically arranged along the height of the sightseeing vehicle 2. That is, the first and second infrared detectors are strip-shaped and can monitor from any position at the height of the sightseeing vehicle 2, detecting any movement of a passenger's head or feet. The alarm device 1 is electrically connected to both the first and second infrared detectors and issues an alert when the second infrared detector emits a monitoring signal before the first infrared detector. The first infrared detector includes a first infrared transmitter 3 and a first infrared receiver 4 (similar to a device commonly used in elevators to detect whether someone is entering or exiting an elevator). The first infrared transmitter 3 and the first infrared receiver 4 are installed opposite each other at corresponding positions on the side of the sightseeing vehicle 2. The second infrared detector includes a second infrared transmitter 5 and a second infrared receiver 6. The second infrared transmitter 5 and the second infrared receiver 6 are also installed opposite each other at corresponding positions on the side of the sightseeing vehicle 2.

[0029] like Figure 7 and 8 As shown, the alarm device 1 includes a housing 7, an MCU, a battery, and a buzzer 8. The housing 7 is mounted on the sightseeing vehicle 2. The MCU and the battery are both located inside the housing 7, and the battery is connected to the power supply terminal of the MCU via a power supply circuit. The buzzer 8 is mounted on the side of the housing 7; preferably, two buzzers 8 are provided. The first infrared detector and the second infrared detector are electrically connected to the signal input terminal of the MCU, and the buzzer 8 is electrically connected to the command output terminal of the MCU.

[0030] When a passenger extends their arm out of the tour bus 2, because the passenger is extending from inside the bus to outside, the second infrared detector (second infrared transmitter 5 and second infrared receiver 6) closer to the passenger will detect it first, while the first infrared detector (first infrared transmitter 3 and second infrared receiver 4) farther away will detect it later. Ultimately, the MCU determines that a passenger is extending their arm out of the tour bus 2 based on the first signal received from the second infrared detector, and then issues a command to the buzzer 8 to alert the passenger. After receiving the audible alert, the passenger returns to a safe sitting position. If the MCU no longer receives signals from the second and first infrared detectors, it issues a command to stop the buzzer 8.

[0031] When a foreign object enters the sightseeing vehicle 2, such as a leaf falling from the roadside, the first infrared detector, which is farther away from the vehicle, will detect it first, while the second infrared detector, which is closer, will detect it later. Similarly, the MCU determines that a foreign object has entered the vehicle based on the signal received from the first infrared detector and will not issue a command to the buzzer 8 to prevent false alarms from affecting driving.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
