Description

车辆防盗装置技术领域 Vehicle anti-theft device

本发明隶属一种车辆防盗技术领域，具体而言指一种可让方向盘机柱分段空转的防盗装置，藉以降低车辆的失窃率。 The invention belongs to the field of vehicle anti-theft technology, and particularly relates to an anti-theft device capable of idling the steering wheel column segment, thereby reducing the theft rate of the vehicle.

近年来偷车贼偷车不再只是为了单纯的卖赃车，甚至是将车辆拆解成零件出售，又或直接向车主勒索，因此车辆的失窃率一直居高不下，而为了避免车辆遭到窃贼偷窃，业界开发有各种防盗设备与装置，如早期的拐杖锁、排挡锁或方向盘锁，乃至近期使用较为广泛的引擎密码锁、芯片锁或卫星 GPS防盗定位***等等，受到窃贼开锁技术的增进与***的开发，前逑这些防盗设备装置也渐渐被破解，以固定方向盘的方向盘锁及拐杖锁为例，窃贼除了开锁外，其亦可直接锯掉方向盘的旋盘，再以工具夹住方向盘机柱的端部，其一样可将车辆偷走；至于引擎密码锁、芯片锁或卫星防盗定位***虽然具有较佳的防护作用，但其价格昂贵，且只要破解其内码，仍然会有车辆被偷走的问题，因此前述防盗设备与防盗***已渐失去作用；又另有业者开发有公告 TW第 159411号「可换式方向盘锁空转结构」及公告 TW第 345141号「方向盘空转防盗结构」等专利前案，前述专利前案主要利用锁具与方向盘旋盘结合成一体的设计，以利用锁具让方向盘的旋盘内套轴与机柱轴心形成空转状态，进而让窃贼无法利用方向盘控制车辆，而达到防盗的目的，其虽然具有较佳的防盗效果，但由于锁具其组成结构易为窃贼复制与破解，反而更容易得手，又其结构极为复杂，窃贼偷窃过程破坏方向盘上如方向灯控制杆、雨刷控制杆、音响控制盘及安全气囊等设备的设置，更甚者窃贼只要取下整个方向盘的旋盘，并以钳具夹掣机柱，其一样可以操控开车，因此前述专利前案的防盗结构未能有效的推广于市面上。 In recent years, car thieves have stolen cars no longer simply to sell cars, even to disassemble them into parts for sale, or to directly extort from the owners, so the theft rate of vehicles has been high, and in order to avoid vehicles Thief stealing, the industry has developed a variety of anti-theft devices and devices, such as early cane locks, gear locks or steering wheel locks, and even the recent use of a wider range of engine code locks, chip locks or satellite GPS anti-theft positioning system, etc., by the thief unlocking technology The development of the promotion and unlocking tools, the anti-theft device devices are gradually cracked. For example, the steering wheel lock and the cane lock of the fixed steering wheel are used. In addition to unlocking the thief, the thief can also directly cut off the steering wheel of the steering wheel and then use the tool. Clamping the end of the steering wheel column, the same can steal the vehicle; as for the engine code lock, chip lock or satellite anti-theft positioning system, although it has better protection, it is expensive, and as long as the internal code is cracked, There will be problems with the vehicle being stolen, so the anti-theft device and the anti-theft system have gradually lost their effect; The patent TW No. 159411 "replaceable steering wheel lock idling structure" and the announcement TW No. 345141 "steering wheel idling anti-theft structure" and other patents have been issued. The aforementioned patents mainly use the combination of the lock and the steering wheel to form an integrated design. The lock shaft is used to make the inner sleeve shaft of the steering wheel and the axis of the machine shaft idling, so that the thief can not use the steering wheel to control the vehicle, and the purpose of theft prevention is better, although it has better anti-theft effect, but the structure of the lock is Easy to copy and crack for thieves, but it is easier to get, and its structure is extremely complicated. The thief stealing process destroys the settings on the steering wheel such as the direction light lever, wiper lever, audio control panel and airbag, even more thieves The disc of the entire steering wheel is removed, and the column is clamped by the clamps, and the same can be controlled to drive. Therefore, the anti-theft structure of the aforementioned patent case has not been effectively promoted on the market.

基于此，为了解决现有车辆防盗作用的不足，且不影响其它设备的设置，本发明人乃开发一种可让方向盘机柱分段空转的车辆防盗装置，如此即便窃贼剪断或取下方向盘旋盘，其仍然无法控制车辆方向，以克服现有只需破坏锁具即可偷走车辆的问题。发明内容 Based on this, in order to solve the deficiencies of the existing vehicle anti-theft function, and without affecting the settings of other devices, the inventors have developed a vehicle anti-theft device that can make the steering wheel column segment idling, so that even if the thief cuts or removes the direction hovering The disc, which still has no control over the direction of the vehicle, overcomes the problem of stealing the vehicle by simply destroying the lock.
