Technical Field

The utility model relates to the field of structural design of locks, in particular to a vehicle door lock with a double-locking safety switch.

Background

A door lock is a device used, as the name implies, to lock a door to prevent others from opening the door. Door locks are classified into a large number of categories, and the requirements for door locks are different in each occasion. The electronic car door lock appears along with the development of electronic technology, and is incomparable with mechanical locks in the aspects of convenience in use, illegal unlocking prevention, intelligent management and the like, so that the electronic car door lock is widely applied to industries with higher safety requirements. The common electronic car door locks mainly comprise magnetic cards, IC cards, TM cards and radio frequency cards.

The door lock must have safety and stability as a security product. Security can be measured from two aspects: one is to resist violent damages such as intentional damage, pranks and intentional prying, drilling and the like. In this respect, mechanical strength of both mechanical and electronic door locks is generally sufficient.

In order to meet the use requirements of more diversification and higher technology, many existing locks integrate a mechanical lock cylinder structure and an electronic lock cylinder structure, and can be unlocked physically by a key and also unlocked non-physically and electronically by a magnetic card, an IC card, a TM card, a radio frequency card and the like.

A safety lock or a safety switch is a locking structure different from a mechanical lock cylinder structure and an electronic lock cylinder structure, and is applied to a vehicle door lock to realize multiple lock locking functions of the vehicle door lock and strengthen the functions of theft prevention and forced removal prevention. When the door lock is unlocked, the safety switch needs to be switched to an unlocking state, and then the unlocking function is realized by unlocking the mechanical lock cylinder structure and/or the electronic lock cylinder structure.

The existing safety locks are all applied to mechanical lock core structures, such as the utility model patent of patent document CN205025081U, which discloses a direct insertion type scaffold with the safety lock, comprising a cross rod and a vertical rod, wherein plugs are arranged at two ends of the cross rod, the plug is provided with an axial wedge surface, two side wedge surfaces and an arc surface, a plurality of wheel discs are arranged on the vertical rod along the axial direction, tapered long holes which are uniformly distributed and matched with the plugs are arranged on the wheel discs, and the safety lock is characterized in that the safety lock is arranged below the wheel discs; the safety lock comprises a connecting part, a fixing part, a rotating part and four clamping teeth; the fixed part is connected with the wheel disc through the connecting part; the rotating part is sleeved on the connecting part; the four clamping teeth are uniformly and symmetrically distributed on the inner side of the rotating part; the axial wedge surface of the plug has a groove that mates with the latch. According to the utility model, the safety lock is additionally arranged below the wheel disc, so that the scaffold is safer and more reliable in use.

Then, the above-mentioned kind of existing product structure can't directly realize the safety lock function to electronic lock core structure, and its product just divides into two kinds: firstly, the electronic lock cylinder structure has no safety lock structure, and the defect that the electronic lock cylinder structure is weak in anti-theft capability and easy to crack; secondly, through adding the structure to the mechanical lock core structure, the locking function of the electronic lock core structure is realized, namely the safety lock function of the electronic lock core structure is indirectly realized, and the defects are that the internal structure is more complicated, the size is increased, and the failure rate is increased.

Therefore, a more optimized safety switch with double locking functions is urgently needed, and under the condition that the existing mechanical lock cylinder structure and the existing electronic lock cylinder structure are not complicated, the safety switch can simultaneously act on the mechanical lock cylinder structure and the electronic lock cylinder structure, so that the overall safety and anti-theft performance of the lock is enhanced.
