technical field

The invention relates to the field of electronic locks, in particular to an electronic lock that is safe and easy to install and can be operated manually.

Background technique

Locks are important home security products. Throughout the ages, people have been accustomed to manually unlocking with a key, but in some occasions where manual unlocking is not convenient, people hope that the lock can be opened automatically. This is a humanized lock demand. But at present, the electronic locks on the market can only be unlocked manually, or can only be automatically unlocked, which cannot meet the needs of humanized locks that can be unlocked manually. . And automatic unlocking electronic lock then has only an electric gear box mechanism, because gear box transmission ratio is big, its output shaft can't be rotated by hand, if two operating mechanisms are used in combination then manual unlocking just can't be used, and also can't emergency unlocking. Therefore, in order to allow the electronic lock to fully meet the humanized operation requirements, the lockset must have a hand-operated operating mechanism. The key is to invent a power gearbox capable of bidirectional clutching, but the current electronic locks do not have such a mechanism. structure. Especially the existing fully automatic locks, because they cannot be manually operated, the electric gear box must work every time when entering and leaving the door, the power consumption is very large, and it needs to be charged frequently, which is inconvenient to use. Being forced to stand and wait for a few seconds for the door to open feels compulsive. In addition, the existing electronic locks, no matter manual locks or fully automatic locks, have only one electromechanical operating mechanism, and mechanical keys must be used for emergency unlocking, which can be opened by technology, which is not safe. The contradiction of convenience has always been a major problem in the world's lock industry. In addition, due to the different shapes and specifications of many locks, the replacement of user locks is also another major problem in the lock industry.

Specific implementation method

In order to make the purpose, technical solutions and advantages of the present invention clearer, further detailed description will be made below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only a preferred embodiment of the present invention, and Do not limit the scope of the present invention.

As shown in Fig. 1, a kind of electronic lock of the present invention is safe and easy to install and can be operated by hand. On the lock body 6 embedded in the door 12, the two ends of the lock core shaft 701 of the transmission lock core 7 are coaxially fixedly connected with the clutch 10 and the clutch power gearbox 3 respectively through the front connecting shaft 8 and the rear connecting shaft 1, The center of the lock core shaft 701 is fixedly connected with the dial 702 .

The front handle 11 is fixedly connected with the shaft of the clutch 10, the rear handle 2 is fixedly connected with the rear connecting shaft 1, and the clutch 10 and the clutch power gearbox 3 are respectively installed in the front and rear lock panels on the outer surface of the door 12. 10 and the clutch power gear box 3 can be installed on the door 12 in different front and rear relative positions, so the lock operating mechanism has two different installation structures: the first structure: the clutch 10 is installed in the front panel 9, and the clutch power gear The box 3 is housed in the rear panel 4 . The second structure: the clutch power gearbox 3 can be contained in the front panel 9, and the clutch 10 is contained in the rear panel 4. This embodiment adopts the first structure.

As shown in Figure 2, a hollow shaft sleeve 201 is cast at the axis of the output gear 20 of the clutch power gearbox 3, and the inner wall of the hollow shaft sleeve 201 is provided with two V-shaped grooves symmetrical to the axis of the output gear. 24. The hollow shaft sleeve 201 is coaxially movably sleeved with a limit sleeve 21, and the limit sleeve 21 is provided with two limit grooves 22 symmetrical to the axis of the output gear. Each of the slots 22 is provided with a needle roller 23. An output shaft 25 is movably socketed coaxially in the limit sleeve 21. The axis of the output shaft 25 has a square through hole 251. The motor 5 and the upper casing of the gear box 301 fixed connection.

The output shaft 25 is provided with a spring 26, one end of the spring 26 is in contact with the inner wall of the upper case 301 of the clutch power gearbox, the other end of the spring 26 is in contact with one end of the limiting sleeve 21, and the other end of the limiting sleeve 21 It is in contact with the inner wall of the gear case lower case 302 .

The working principle of the present invention is as follows:

In a safe, easy-to-install and manual-operated electronic lock embodiment of the present invention, the clutch power gearbox 3 must first have a clutch function. When it is normal in Fig. 2, A-A, the hollow shaft sleeve 201 does not move. There is a gap between the needle roller 23 and the slope of the V-shaped groove 24 of the hollow shaft sleeve 201, and the output shaft 25 can rotate freely. When the hollow shaft sleeve 201 rotates, the slope of the V-shaped groove 24 simultaneously squeezes two Two needle rollers 23, the gap between the needle roller 23 and the V-shaped groove 24 disappears, so that the two needle rollers 23 are forced to clamp the output shaft 25. At this time, the hollow shaft sleeve 201 drives the output shaft 25 to rotate synchronously. The shaft sleeve 201 stops rotating, and when the output shaft 25 is rotated in the same direction by hand, the surface friction force of the output shaft 25 drives the needle roller 23 to leave the slope of the V-shaped groove 24 to create a gap. At this time, the output shaft 25 can rotate freely in both directions. A two-way overrunning clutch structure is formed between the output shaft 25 and the hollow shaft sleeve 201 , thereby realizing the clutch function of the clutch power gearbox 3 .

When normal, because the output shaft 25 and the output gear 20 of the clutch power gearbox 3 are in a separated state, the rear handle 2 can be directly rotated by hand and the lock body 6 is opened and locked by the rear connecting shaft 1. When the clutch 10 is normal, it is also Be in disengagement state, front handle 11 can only idling, can not operate dial 702 to unlock outside the door, when clutch 10 is closed, rotate front handle 11 by hand and drive lock core shaft 701 and dial 702 to unlock through front connecting shaft 8, also Available electronic control mode, through the clutch power gearbox 3 drives the rear connecting shaft 1, the lock core shaft 701 and the dial 702 to realize automatic unlocking.

It should be noted that: the above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still The technical solutions described in the foregoing embodiments are modified, or some of the technical features are equivalently replaced.
