Technical Field

The utility model belongs to the technical field of vehicle safety alarm device technique and specifically relates to an alarm device for preventing wheel drops.

Background

The automobile is a widely used transportation tool in modern society, and the automobile often has a traffic accident that wheels fall off in the driving process, and the sudden property of the wheel fall off often causes serious consequences. Therefore, the prevention of the wheel falling off in the driving process of the automobile is a common desire and responsibility of drivers.

The wheels are rigid wheels which fix the inner edge of the tire, support the tire and bear load together with the tire, and the wheels and the tire are called a wheel assembly together, and the wheel assembly has the functions of bearing the whole vehicle mass and transmitting traction force, braking force, driving torque and braking torque; the impact and vibration generated by the uneven road surface are alleviated and absorbed; the adhesion performance of the wheels and the ground is improved. The wheels are connected to the brake disc through bolts, and the mode of checking bolts, nuts and tire carcasses is mainly adopted for preventing the tires from falling off by drivers at present.

However, in the actual driving process of the vehicle, the wheel drop phenomenon still occurs due to the quality problem of the automobile parts, the aging of the vehicle, the negligence of inspection or the sudden abnormal condition, so that a system capable of early warning in time and preventing the wheel drop is very necessary.

Disclosure of Invention

In order to solve the problem, the utility model provides an alarm device for preventing wheel drops installs on the frame, can in time catch the skew information of wheel, reminds the driver in time to park the inspection, avoids the emergence of wheel drop incident, and this system has early warning tire pressure function simultaneously.

In order to realize the technical purpose, the technical effect is achieved, the utility model discloses a realize through following technical scheme: the utility model provides an alarm device for preventing wheel drops, includes the sensor, sensor quantity is four, and the symmetry is installed in the frame outside respectively, locates between frame and the wheel, and four sensor transmission signal are connected with the alarm through the connecting wire after the treater is handled, and the sensor probe has antifouling device, and is perpendicular with frame mutually perpendicular, and is perpendicular with the tire side.

Furthermore, the sensor capturing signal can also be electrically connected with a driving control unit ECU of the vehicle, and the display alarm is carried out through a vehicle instrument panel.

Furthermore, the alarm is provided with an automatic reset function.

The utility model has the advantages that:

1. the sensor of the device can directly connect the signal processed by the processor to the self-made display screen for displaying, and the sensor can also be connected to the driving control unit ECU by a manufacturing enterprise and then conducted to the instrument panel, so that the device can be conveniently installed in the existing automobile and is convenient to apply;

2. this early warning device of wheel installation can be when the wheel has certain offset timely early warning, thoroughly prevents the emergence of wheel dropout incident, can play the early warning effect to tire pressure anomaly simultaneously, protects driver's the security of the lives and property.

Drawings

Fig. 1 is a schematic structural diagram of the device of the present invention.

The device comprises an alarm 1, a connecting wire 2, a sensor 3, a probe antifouling cover 31, a wheel 4, a frame 5 and a processor 6.

Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided with reference to fig. 1, so that the advantages and features of the present invention can be easily understood by those skilled in the art, and thus, the protection scope of the present invention can be defined more clearly and clearly.

The utility model provides a warning device for preventing wheel drops, including sensor 3, 3 quantity of sensor are four, the symmetry is installed in the frame 5 outside respectively, locate between frame 5 and the wheel 4, four 3 transmission signal of sensor are connected with alarm 1 through connecting wire 2 after 6 processing of treater, 3 probes of sensor have antifouling device 31, with frame 5 mutually perpendicular, perpendicular with the tire side, automobile enterprise's sensor catches data and also can link to each other with the driving control unit ECU electrical property of vehicle, show the warning through the vehicle panel board, alarm 1 is equipped with the automatic re-setting function.

The system is different from mechanical principle anti-loosening and anti-falling, and aims at the problem that when an actual wheel is about to fall off, early warning is carried out through distance sensing, the last line of defense is completely held, when an automobile normally runs, a check ring is in a plane (within a tolerance range) in the continuous rotation process, when the wheel falls off, the wheel firstly loosens, and the plane where the wheel and a tire are located can deviate inwards and outwards until the wheel and the tire fall off finally. Design such a device, utilize the change of this kind of distance in time catching the wheel rotation of distance sensing technology, and conduct and give driving control unit ECU, finally conduct the panel board, or the signal does not pass through driving control unit ECU, directly pass to the little screen of self-control warning through the treater, remind the driver to park and inspect the wheel, prevent the emergence of wheel obscission, the sensor is installed usually in the suitable position of automobile body apart from wheel tire certain distance, concrete motorcycle type and detailed distance will be tested in the experiment and reachd, output signal directly transmits alarm device through the treater. The distance between the tire and the sensor can be changed due to the change of the tire pressure, so that the tire pressure can also play a role in early warning when the change of the tire pressure is large, short-time warning caused by steering or line-changing overtaking is judged by a driver in the actual use process, and a warning signal can automatically disappear when the vehicle runs to a normal road section. The early warning system for the wheel installation can give an early warning in time when the wheel has a certain offset, thoroughly prevents the occurrence of a wheel falling event, and can play an early warning role in tire pressure abnormity.

Example (b): the system firstly utilizes the distance sensor to capture the distance change between the plane of the inner side of the wheel tire and the position of the sensor, sets suitable parameters according to different types of vehicles and different installation positions of the sensor, and the sensor transmits the captured data to the processor to form an output signal and send an early warning signal. Meanwhile, when the tire pressure is abnormal, the distance between the tires is abnormal, and the processor can also send out an early warning signal. The signal is connected to a display screen through a processor, and the display screen is installed around a vehicle instrument panel. In addition, the automobile manufacturing enterprise can change in design, transmit signals to the vehicle control unit ECU, and then give an alarm through the vehicle instrument panel.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used for the transformation, or directly or indirectly applied to other related technical fields, which are all included in the same way in the patent protection scope of the present invention.
