[0002] With the increasing number of stray animals in cities, the phenomenon of animals seeking warmth in car engine compartments is becoming more and more common, with even cases of mother cats giving birth inside engine compartments. When car owners start their cars, it is difficult to detect whether there are animals in the engine compartment, which may directly cause injury or death to the animals. This not only harms the animals' lives but also pollutes and damages the engine, posing safety hazards and inconvenience to car owners.

[0003] While existing animal deterrent devices can repel animals to some extent, they still have many shortcomings. For example, a utility model patent with publication number CN216058952U discloses an infrared ultrasonic cat repellent, which is mainly used for repelling cats in fixed settings such as gardens or balconies, and is not suitable for environments where cars travel in multiple locations. In addition, the repelling effect of ordinary ultrasonic waves is limited, and it is difficult to temporarily use cat repellents for newborn animals that cannot move freely.

[0004] Therefore, there is an urgent need for a vehicle-mounted device that can intelligently detect the presence of living creatures inside a car's engine and chassis, effectively drive animals away, and also provide obstacle avoidance reminders to the driver, in order to overcome the shortcomings of existing technologies and improve vehicle driving safety and animal protection.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1 to 5 As shown, this embodiment of the present invention provides a vehicle-mounted pulsed ultrasonic deflector device, including a fixed plate 3, a triangular housing 1 elastically connected to the bottom of the fixed plate 3, an ultrasonic generator and an infrared detector disposed on the outer periphery of the triangular housing 1. The infrared detector is provided in three sets, each set including an infrared emitting lamp 6, an infrared probe 7, and a protective cover 9 for protecting the infrared probe 7. The ultrasonic generator includes an ultrasonic transducer 8. The triangular housing 1 is elastically connected to the fixed plate 3 via a central damping spring 4 and multiple small damping springs 5 ​​distributed around the central damping spring 4. The fixed plate 3 is provided with a straight hole 19 for connection to the vehicle chassis.

[0032] like Figure 2 and Figure 4As shown, the triangular shell 1 is a triangular prism structure, including three sides. Infrared emitting lamp limiting holes 11 and infrared probe limiting holes 12 are respectively opened on the three sides. One side also has an ultrasonic transducer limiting hole 10. Ultrasonic transducer fixing ring 20, infrared emitting lamp fixing ring 21 and infrared probe fixing ring 22 are respectively fixed in the ultrasonic transducer limiting hole 10, infrared emitting lamp limiting hole 11 and infrared probe limiting hole 12. Each limiting hole and fixing ring is used to install the infrared ultrasonic transducer 8, infrared emitting lamp 6 and infrared probe 7.

[0033] The three sets of infrared detectors are respectively installed on the three sides of the triangular shell 1, obtaining a certain range of detection coverage area on the outer periphery of the triangular shell 1. Among them, the infrared emitting lamp 6 emits infrared light, which is then received by the infrared probe 7 to obtain information. Each infrared probe 7 has a detection range of 150° outside the triangular shell 1, achieving full-range detection in the area outside the center of the triangular shell 1 with a radius of 6.5 cm.

[0034] like Figure 4 As shown, a central inner plate 13 is fixed inside the triangular shell 1. The central inner plate 13 is used to place the circuit board 14 and the battery 17. The battery 17 is a rechargeable power supply, which facilitates powering the device.

[0035] In the above embodiment, the circuit board 14 is preferably a microcontroller, utilizing existing microcontroller control technology and analysis algorithms to realize the operation of the device. The ultrasonic transducer 8 and the infrared detector are respectively connected to and controlled by the circuit board 14.

[0036] like Figure 2 As shown, a shell cover plate 2 is installed on the top of the triangular shell 1. The shell cover plate 2 is a triangular plate that matches the shape of the triangular shell 1. The shell cover plate 2 has shock-absorbing spring limiting grooves 15 that correspond to the positions of the central shock-absorbing spring 4 and the small shock-absorbing spring 5, respectively, for assembling the central shock-absorbing spring 4 and the small shock-absorbing spring 5.

[0037] like Figure 2 and Figure 3 As shown, a switch 16 for controlling the operation of the device is installed on the housing cover 2, and multiple ventilation structures 18 are also provided on the housing cover 2 for ventilation and heat dissipation inside the triangular housing 1. Figure 5 As shown, the ventilation structure 18 adopts an inverted U-shaped structure, including a ventilation structure body 23 and a ventilation channel 24 disposed within the ventilation structure body 23. The ventilation structure body 23 is a hemispherical structure, which is not easy for water and dust to enter. The ventilation channel 24 is inverted U-shaped, with one end connected to the interior of the triangular shell 1 and the other end located above the shell cover plate 2, with the opening facing downwards. This can reduce the amount of dust entering the device, and while achieving ventilation, it can also prevent dust from entering the device to a greater extent, making it more suitable for the dusty environment under the car.

[0038] like Figure 2 As shown, in one specific embodiment, the ultrasonic transducer 8 is installed at the ultrasonic transducer limiting hole 10 on the side of the triangular housing 1 facing the car engine, and is fixed by the ultrasonic transducer fixing ring 20. The circuit board 14 starts the device according to the car stop signal and sends an electrical signal to the ultrasonic transducer 8 according to the situation detected by the infrared detector. The ultrasonic transducer 8 converts the electrical signal into a pulsed ultrasonic signal to drive away the animal inside the car engine. The pulsed ultrasonic wave is an ultrasonic pulse of 5-6MHz, 68μs, and peak intensity of 30W / cm inserted into a frequency conversion audio frequency of 20000-60000Hz. This pulsed ultrasonic wave will stimulate the cat's nerves, thereby producing a sense of unease, and is more effective than ordinary ultrasonic waves in driving away animals.

[0039] Working principle of this utility model embodiment:

[0040] like Figure 6 and Figure 7 As shown, install this device on the car chassis, ensuring the mounting plate 3 is securely connected to the chassis. Ensure the ultrasonic generator is aligned with the car engine. Connect the device to the car's power supply and to the car's drive controller and motion control system. In use, turn on switch 16 to activate the device, which then connects to the car via Bluetooth. When the device receives a signal indicating the car has stopped, it activates the infrared detector on the side with the ultrasonic generator to monitor the environment around the car chassis, especially the engine area. When the infrared detector detects a living creature entering the engine, circuit board 14 transmits a pulsed electrical signal to the ultrasonic transducer 8, causing it to emit pulsed ultrasonic waves to repel the creature. When the device receives a signal indicating the car is about to start, it activates all infrared detectors to check for nearby living creatures around the car. If a creature is detected, a warning is sent to the car's display screen.
