Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

A passive lock cylinder provided by an embodiment of the present invention will now be described with reference to the accompanying drawings.

Referring to fig. 1 to 12, a passive lock cylinder includes a lock housing 100 and a lock core 200, a lock hole 110 is disposed in the lock housing 100, the lock hole 110 is disposed in the lock housing 100, a first contact groove 120 and a second contact groove 130 are disposed on an inner sidewall of the lock hole 110, the lock core 200 is inserted into the lock hole 110 and can rotate on the lock housing 100, a first probe 210 and a second probe 220 are disposed thereon, the first probe 210 and the second probe 220 extend out from a rotating sidewall of the lock core 200, wherein the first probe 210 extends into the first contact groove 120, the second probe 220 extends into the second contact groove 130, and the first contact groove 120 and the second contact groove 130 have a pushing portion or a pushing surface for pushing and triggering the first probe 210 and the second probe 220, respectively.

When the lock core 200 rotates along the first direction, the first contact groove 120 triggers the first probe 210 first, and the second contact groove 130 triggers or does not trigger the second probe 220 later; when the cylinder core 200 rotates in the second direction, the second contact groove 130 first triggers the second probe 220, and the first contact groove 120 then triggers or does not trigger the second probe 220, where the second direction is opposite to the first direction, and referring to fig. 4, when the first direction (i.e., the direction X in fig. 4) is clockwise rotation of the cylinder core 200, the second direction (i.e., the direction X in fig. 4) is counterclockwise rotation of the cylinder core 200.

When the direction of opening and closing the lock is determined by the contact sequence of the two probes, the triggering sequence of the first probe 210 and the second probe 220 can be controlled according to the distance from the abutting portions of the first contact groove 120 and the second contact groove 130, because the inner side wall of the lock hole 110 is a circumferential side wall, the first contact groove 120 and the second contact groove 130 both have two spaced abutting portions in the circumferential direction of the lock hole 110, and the two abutting portions on the contact grooves are the triggered positions of the probes in the first direction and the second direction respectively. When the lock core 200 is unlocked and locked on the lock case 100, the lock core 200 has an initial state position, i.e. a key access position, in the initial position, the distance between the pushing portion of the first probe 210 in the first direction in the first contact groove 120 is shorter than the distance between the pushing portion of the second probe 220 in the first direction in the second contact groove 130, so that the lock core 200 first triggers the first probe 210 and then triggers the second probe 220 when rotating in the first direction, and correspondingly, the distance between the pushing portion of the first probe 210 in the second direction in the first contact groove 120 is longer than the distance between the pushing portion of the second probe 220 in the second direction in the second contact groove 130, so that the lock core 200 first triggers the locking and then triggers the first probe 210 when rotating in the second direction.

In addition, when the locking direction is determined only by the sequential triggering sequence of the two probes, only one abutting portion may be disposed on the first contact groove 120 and the second contact groove 130, the abutting portion on the first contact groove 120 is disposed on the first direction of the first probe 210, the abutting portion on the second contact groove 130 is disposed on the second direction of the second probe 220, when the lock core 200 rotates in the initial state in the first direction, the abutting portion of the first contact groove 120 triggers the first probe 210, the second contact groove 130 does not trigger the second probe 220, at this time, the lock core 200 records that the rotation direction thereof is the unlocking direction or the locking direction, and when the lock core 200 rotates in the second direction, the abutting portion of the second contact groove 130 triggers the second probe 220, the first contact groove 120 does not trigger the first probe 210, at this time, the rotation direction recorded by the lock core 200 is the locking direction or the unlocking direction. In a special case, when the first contact groove 120 and the second contact groove 130 are annular grooves formed in the inner side wall of the lock hole 110, after the lock core 200 rotates for one circle, the two probes must sequentially pass through the abutting portions of the corresponding contact grooves, and therefore the lock core 200 can also determine the rotation direction of the lock core 200 on the lock case 100 according to the sequential triggering sequence of the two probes.

Compared with the prior art, the invention utilizes two probes as direct contact parts for detection, when the lock core 200 rotates in the lock shell 100, the sequence of contact of the two probes is used for judging whether the lock core 200 is in the unlocking direction or the locking direction, when the lock core 200 rotates towards the first direction, the first contact groove 120 utilizes the groove surface of the first contact groove to push the first probe 210 to retract, so that the control circuit on the lock core 200 detects that the direction is the unlocking direction, and when the lock core 200 rotates towards the second direction, the second contact groove 130 pushes the second probe 220 firstly, which is different from the trigger mode of the lock core 200 in the first direction, thereby the passive lock core has the function of identifying the unlocking direction, the locking information is fed back to the hands of users in time, the trouble that the rotation direction of the users is not clear during unlocking is solved, and the use experience of the passive lock core is improved.

In an embodiment of the present invention, referring to fig. 3 and 4, the first contact groove 120 and the second contact groove 130 are disposed on the inner sidewall of the lock hole 110 along the circumferential direction of the lock hole 110, that is, the first contact groove 120 and the second contact groove 130 are circumferential strip-shaped grooves disposed on the inner sidewall of the lock hole 110, the first contact groove 120 and the second contact groove 130 are axially staggered on the lock hole 110, that is, the first contact groove 120 and the second contact groove 130 are not overlapped on the inner sidewall of the lock hole 110, the first probe 210 and the second probe 220 move in the respective independent contact grooves, the two ends of the first contact groove 120 and the two ends of the second contact groove 130 are the above-mentioned pushing parts, and during the rotation of the lock core 200 in the lock case 100, the first probe 210 and the second probe 220 are triggered in a manner of being separated from the first contact groove 120 and the second contact groove 130, so as to have a triggered sequence.

In addition, the first contact groove 120 and the second contact groove 130 may be overlapped contact grooves, which can also achieve the operation of the present invention.

Further, a detection head 260 is arranged in the lock core 200, and the first probe 210 and the second probe 220 are arranged on the detection head 260 in an axial direction pressing the lock hole 110. Because the first contact groove 120 and the second contact groove 130 are independent contact grooves and are staggered axially, the first probe 210 and the second probe 220 determine the separation sequence of the first probe 210 and the second probe 220 on the corresponding contact grooves according to the staggered sequence of the first contact groove 120 and the second contact groove 130 in the process of flush rotation, and then the trigger sequence of the two probes is obtained. In a specific implementation process, referring to fig. 2, the first contact groove 120 and the second contact groove 130 are contact grooves with the same width disposed on the lock hole 110, wherein the staggered direction of the first contact groove 120 is located in the second direction of the second contact groove 130, so that when the lock core 200 rotates in the first direction, the first probe 210 and the second probe 220 leave the first contact groove 120 and the second contact groove 130 successively, and when the lock core 200 rotates in the second direction, the sequence is the same as that of the present invention.

Specifically, the first touch slot 120 and the second touch slot 130 are both arc-shaped slots, and the first touch slot 120 and the second touch slot 130 have the probe non-trigger part 140 that is axially overlapped, that is, when the first probe 210 and the second probe 220 are located at the probe non-trigger part 140, they are in a suspended or light touch state, and do not trigger the internal circuit located in the detection head 260. According to the arc-shaped first contact groove 120 and the arc-shaped second contact groove 130, when the first probe 210 or the second probe 220 leaves the first contact groove 120 or the second contact groove 130, the arc-shaped inclined planes at the two ends of the contact grooves gradually push the probes, so that the probes conduct the detection circuit inside the detection head 260. Of course, the first contact groove 120 and the second contact groove 130 may also be trapezoidal grooves, which are not described herein.

The spherical surface allows the initial lock member 240 to be disengaged from the lock groove 150 as the cylinder barrel 200 rotates, and similarly, the initial lock member 240 may be disengaged from the lock groove 150 during rotation by providing the lock groove 150 as a spherical groove or providing an engagement portion of the initial lock member 240 in the lock groove 150 as a spherical structure.

Also in this embodiment, the movable channel 250 is a narrow opening at the end of the keyway 230, with a diameter smaller than the diameter of the locking ball, so that the initial locking member 240 cannot escape the movable channel 250 into the keyway 230.
