Description

Technical Field

[0001] The invention relates to the field of structural design of locks, in particular to a vehicle door lock with a double locking safety switch. Background Art

[0002] As the name implies, a car door lock is a device used to lock the car door to prevent others from opening the door. There are many types of car door locks, and the requirements for car door locks are different in different occasions. Electronic car door locks emerged with the development of electronic technology. They are incomparable to mechanical locks in terms of convenience, anti-illegal opening, and intelligent management. Therefore, they are widely used in industries with high security requirements. The most common electronic car door locks on the market are magnetic card, IC card, TM card, and radio frequency card.

[0003] As a security product, car door locks must be safe and stable. Safety can be measured from two aspects: one is resistance to vandalism, pranks, and deliberate prying, drilling and other violent damage. In this regard, the mechanical strength of mechanical locks and electronic car door locks can generally meet the requirements.

[0004] In order to meet more diverse and higher-tech usage needs, many existing car door locks integrate mechanical lock cylinder structure and electronic lock cylinder structure, which can be physically unlocked by key, and non-physical electronic unlocking by magnetic card, IC card, TM card, radio frequency card, etc.

[0005] A safety lock or safety switch is a locking structure that is different from a mechanical lock core structure and an electronic lock core structure. It is used in car door locks to achieve the multi-lock function of the car door lock and enhance the anti-theft and anti-demolition functions. When unlocking the car door lock, you need to first switch the safety switch to the unlocked state, and then unlock the mechanical lock core structure and / or the electronic lock core structure to achieve the unlocking function.

[0006] Existing safety locks all act on mechanical lock core structures, such as the invention patent of patent document CN205025081U, which discloses a plug-in scaffold with a safety lock, including a crossbar and a vertical pole, plugs are provided at both ends of the crossbar, and the plugs have an axial wedge surface, two side wedge surfaces and an arc surface, and a plurality of wheels are provided on the vertical pole along the axial direction, and the wheel discs are provided with evenly distributed conical long holes that match the plugs.

[0007] The invention is characterized in that a safety lock is provided below the wheel disc; the safety lock comprises a connecting part, a fixing part, a rotating part and four latching teeth; the fixing part is connected to the wheel disc through the connecting part; the rotating part is sleeved on the connecting part; the four latching teeth are evenly and symmetrically distributed inside the rotating part; the axial wedge-shaped surface of the plug has a groove matched with the latching teeth. The invention adds a safety lock below the wheel disc, so that the scaffold is safer and more reliable when in use.

[0008] Then, the above-mentioned existing product structures cannot directly realize the safety lock function of the electronic lock core structure, and its products are divided into two categories: first, the electronic lock core structure has no safety lock structure, and its defect is that the anti-theft ability of the electronic lock core structure is weak and it is easy to be cracked; second, by adding structure to the mechanical lock core structure to realize the locking function of the electronic lock core structure, that is, indirectly realizing the safety lock function of the electronic lock core structure, its defect is that the internal structure is more complicated, the size is increased, and the failure rate will also increase accordingly.

[0009] Therefore, there is an urgent need for a more optimized safety switch with dual locking functions, which can act on both the mechanical lock core structure and the electronic lock core structure while ensuring that the existing mechanical lock core structure and the electronic lock core structure are not complicated, thereby enhancing the overall security and anti-theft performance of the lock. Summary of the invention

[0010] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides a vehicle door lock with a double locking safety switch.

[0011] The technical solution of the present invention to solve the technical problem is: a vehicle door lock with a double locking safety switch, comprising a lock housing, a mechanical lock cylinder and an electronic lock cylinder arranged in the lock housing, and a double locking safety switch, wherein the double locking safety switch comprises a mechanical lock safety component and an electronic lock safety component;

[0012] The mechanical lock safety component is used to lock the mechanical lock core, the electronic lock safety component is used to lock the electronic lock core, and the electronic lock safety component is synchronously linked with the mechanical lock safety component.

[0013] Preferably, the electronic lock safety assembly includes a locking state signal transmitting device, the electronic lock core includes a locking state signal receiving device, and the locking state signal transmitting device is communicatively connected with the locking state signal receiving device.

[0014] Preferably, the locking state signal receiving device is a magnetic signal receiving device, and the locking state signal transmitting device is a magnetic signal transmitting device arranged on the mechanical lock safety component, and the magnetic signal transmitting device forms a magnetic induction connection with the magnetic signal receiving device.

[0015] Preferably, the locking state signal receiving device is a micro switch, and the locking state signal transmitting device is a protrusion arranged on the mechanical lock safety component. The user operates the mechanical lock safety component so that the protrusion on the mechanical lock safety component abuts against the micro switch and triggers the micro switch.

[0016] Preferably, the mechanical lock safety assembly includes a seesaw and a reset elastic member acting on the seesaw, one end of the seesaw is a locking end, and the other end is an unlocking end, and a user presses the unlocking end to change the position of the locking end.

[0024] Electronic part: The electronic lock core includes a circuit board and an electronically controlled unlocking command verification module (such as a fingerprint lock acquisition module, a password lock acquisition module, an induction card lock acquisition module, a communication software lock acquisition module, etc.). The mechanical lock insurance component can drive the electronic lock insurance component to change position during movement, so that the circuit board receives the change information, and the electronic lock insurance component releases the locking effect on the electronic lock core. The user can then perform further operations (through the electronically controlled unlocking command verification module) to unlock the electronic lock core. If the mechanical lock insurance component is reset, the electronic lock insurance component can be reset and locked together.

DETAILED DESCRIPTION

[0035] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] Reference Figures 1 to 8A vehicle door lock with a double locking safety switch 4 comprises a lock housing 1, a mechanical lock cylinder 2 and an electronic lock cylinder 3 arranged in the lock housing 1, and a double locking safety switch 4, wherein the double locking safety switch 4 comprises a mechanical lock safety component and an electronic lock safety component; the mechanical lock safety component is used to lock the mechanical lock cylinder 2, the electronic lock safety component is used to lock the electronic lock cylinder 3, and the electronic lock safety component is synchronously linked with the mechanical lock safety component.

[0037] The above scheme is the basic scheme of the present invention, which can unlock and lock the mechanical lock cylinder 2 and the electronic lock cylinder 3 respectively through the setting and operation of the mechanical lock safety component and the electronic lock safety component, that is, a single double lock safety switch 4 can be used. In addition, the electronic lock safety component is synchronously linked with the mechanical lock safety component, that is, the user can release or lock the mechanical lock cylinder 2 and the electronic lock cylinder 3 at the same time with one operation.

[0038] In order to realize the function of the electronic lock safety component, it includes a locking state signal transmitting device 5, and the electronic lock core 3 includes a locking state signal receiving device 6, and the locking state signal transmitting device 5 is communicatively connected with the locking state signal receiving device 6.

[0039] There are various ways to configure the locking state signal transmitter 5 and the locking state signal receiver 6. Here, two preferred solutions are provided:

[0040] 1. The locking state signal receiving device 6 is a magnetic signal receiving device, and the locking state signal transmitting device 5 is a magnetic signal transmitting device arranged on the mechanical lock safety component, and the magnetic signal transmitting device forms a magnetic induction connection with the magnetic signal receiving device. When in use, the user operates the electronic lock safety component to change the position of the magnetic signal transmitting device, and the position change can change the magnetic induction connection between the magnetic signal transmitting device and the magnetic signal receiving device, and then the position change information is fed back to the electronic lock core 3, and the electronic lock core 3 is unlocked or locked according to the signal. More specifically, the magnetic signal generating device is a magnetic part, and the magnetic signal receiving device is a reed switch connected to the circuit of the electronic lock core 3. The position change of the magnetic part can change the circuit of the electronic lock core 3 through the reed switch.

[0041] Second, the locking state signal receiving device 6 is a micro switch, and the locking state signal transmitting device 5 is a convex block arranged on the mechanical lock safety component. The user operates the mechanical lock safety component, so that the convex block on the mechanical lock safety component abuts against the micro switch and triggers the micro switch. The micro switch is connected to the circuit of the electronic lock cylinder 3. When in use, the user operates the electronic lock safety component, so that the position of the convex block and the micro switch changes (contact or separation), and then the micro switch feeds back the information of the position change to the electronic lock cylinder 3, and the electronic lock cylinder 3 is unlocked or locked according to the signal.

[0042] The above scheme is only a preferred scheme of the locking state signal transmitting device 5 and the locking state signal receiving device 6, and does not limit the present invention in any way, and is not specifically limited here.

[0043] In order to realize the unlocking and locking functions of the mechanical lock cylinder 2 by the mechanical lock safety assembly, its specific structure is as follows: it includes a seesaw 7 and a reset elastic member 8 acting on the seesaw 7, one end of the seesaw 7 is connected to the locking end 9, and the other end is the unlocking end 10. The user presses the unlocking end 10 to change the position of the locking end 9. More specifically, the middle position of the seesaw 7 is rotatably connected to the lock housing 1 through a rotating shaft 11, and the reset elastic member 8 is sleeved on the rotating shaft 11. The reset elastic member 8 has a pressing portion 12, and the pressing portion 12 acts on the seesaw 7 so that the locking end 9 always has a movement tendency to rotate toward the mechanical lock cylinder 2 to ensure a good reset function. In the seesaw 7 type mechanical lock safety assembly of the above structure, pressing the unlocking end 10 unlocks the locking end 9, and releasing the unlocking end 10 resets the entire seesaw 7 under the elastic force of the reset elastic member 8.

[0044] Preferably, the resetting elastic member 8 is preferably a torsion spring, which is sleeved on the rotating shaft 11 and symmetrically distributed on both sides of the rocker 7. A pressing column 20 is convexly provided in the middle of the rocker 7. The pressing portion 12 of the torsion spring abuts against the pressing column 20 to act on the entire rocker 7. Further, the locking state signal emitting device 5 is installed on the pressing column 20.

[0045] For easy operation, the mechanical lock safety assembly further includes a button switch 13, which is opposite to the unlocking end 10 and can contact the unlocking end 10. The button switch 13 can be a separate molding structure from the unlocking end 10, or an integral molding structure, which is not particularly limited here.

[0046] When the button switch 13 is not in operation with the return spring 14 , it feels loose and is prone to not being in place when pressed or returned. Therefore, by setting the return spring 14 , in this embodiment, the mechanical lock safety assembly also includes a return spring 14 acting on the button switch 13 .

[0047] In this embodiment, a switch bracket 15 is further included, and the double locking safety switch 4 is mounted on the switch bracket 15. Through the arrangement of the switch bracket 15, a specific matching mounting structure is provided for the double locking safety switch 4, making the use of each component more stable and reliable.

[0048] In the present invention, the mechanical lock core 2 includes a locking block 16 that cooperates with the mechanical lock safety component. The locking block 16 is provided with a locking groove 17. When the locking end 9 is located in the locking groove 17, the locking block 16 cannot move, that is, the mechanical lock core 2 is in a locked state; when the locking end 9 leaves the locking groove 17, the locking block 16 can move freely, that is, the mechanical lock core 2 is in an unlocked state, and the user can unlock the mechanical lock core 2 by further operation. At the same time, under the action of the reset elastic member 8, the locking end 9 presses against the side wall of the locking block 16 and always has a movement tendency to rotate toward the mechanical lock core 2. Once the locking block 16 moves to the position where the locking groove 17 is relative to the locking end 9, the locking end 9 automatically enters the locking groove 17 and re-locks.

[0049] The electronic lock cylinder 3 includes a circuit board 18 and an electronically controlled unlocking instruction verification module 19 (such as a fingerprint lock acquisition module, a password lock acquisition module, an induction card lock acquisition module, a communication software lock acquisition module, etc.). The mechanical lock insurance component can drive the electronic lock insurance component to change position during the movement, so that the circuit board 18 receives the change information, so that the electronic lock insurance component releases the locking effect on the electronic lock cylinder 3. The user can unlock the electronic lock cylinder 3 by further operation (through the electronically controlled unlocking instruction verification module 19). If the mechanical lock insurance component is reset, the electronic lock insurance component can be reset and locked together.
