The invention discloses a self-powered automobile tire hub burglar alarm which comprises a plurality of machine bodies installed on a brake disc, an energy supply cavity, an energy storage cavity and a detection groove are formed in each machine body from top to bottom, and a micro generator is embedded between each energy supply cavity and the corresponding energy storage cavity. A motor shaft of the micro generator extends into the energy supply cavity and is provided with a rotating sleeve, a plurality of gravity follow-up rods are symmetrically installed on the rotating sleeve, and a gravity magnetic block is installed at the end, away from the rotating sleeve, of each gravity follow-up rod. The brake disc is used for driving each machine body to rotate, so that the gravity follow-up rod and the gravity magnetic block rotate in the energy supply cavity, rotating mechanical energy is efficiently converted into electric energy to be stored through an annular winding and the micro generator, an alarm circuit is connected through a detection rod to give an alarm after the bolt is disengaged from the detection groove, and the safety anti-theft capacity and the alarm capacity are improved; and the occupied space is small, and the device is hidden and is not easy to perceive.
本发明公开了一种自供电汽车轮胎轮毂防盗报警器,包括安装在制动盘上多个机体,所述机体内从上到下分别开设有供能腔、储能腔和检测槽,所述供能腔和储能腔之间嵌设有微型发电机,所述微型发电机的电机轴延伸至供能腔内并安装有转套,所述转套上对称安装有多个重力随动杆,每个所述重力随动杆远离转套的一端均安装有重力磁块。本发明通过利用制动盘带动机体转动使得重力随动杆和重力磁块在供能腔中转动并通过环形绕组和微型发电机将转动机械能高效转换为电能存储,通过检测杆在螺栓脱离检测槽后接通报警电路报警,增加安全防盗能力以及报警能力,且占用空间较小,较为隐蔽,不易被察觉。
