For convenience of explanation, the latching head 42 of the false latching device 30 is in the upper latching position, and the locking member 70 is in the released position, in which the unlatching member 50 is allowed to pivot, and in addition, the releasing end 157 of the driving member 155 and the pressing lever 48 abuts, the latch 42 is in the upper latch position (as shown in Figures 3 and 4), so if the outer handle 82 of the outer operating device 76 is rotated, the drive lever 84 interlocks the push arm 54 of the unlatching member 50 to push the push rod 46 abuts the tractor 44, causing the latch 42 to be displaced from the upper latch position to the unlatching position, and the latch 42 is in the unlatched position to release the outer handle 82, the latch 42 being biased by a spring to be associated with the tractor 44 Reset.

It is assumed that the locked state of the outer lock 88 of the outer lock cylinder 86 is released using the correct key, allowing the outer lock 88 to be used to bias the outer dial 90 against the second end 60 of the drive block 56, such that the drive block 56 pivots. And the first end 58 pivots the rocker arm 62 to pivot, causing the locking member 70 to be displaced to the locked position by the release position (as shown in FIG. 3, the door lock 10 is unlocked) (as shown in FIG. 8 , the door lock 10 In the locked state, the pressing portion 74 of the locking member 70 presses against the second sensing member 174, causing the second sensing member 174 to output a signal to the light-emitting device 193, and further the light-emitting device 193 generates light and Displayed on the translucent cover 195, the light generated by the illumination device 193 of the inboard operating device 92 can be judged that the door lock 10 is locked (the outer end handle 82 of the outer operating device 76 cannot be operated to displace the latch 42 to the unlatching position), In a state where the locking member 70 is in the locked position, the blocking portion 72 of the locking member 70 is offset from the groove 55 of the unlatching member 50, The pivoting path of the latch 50 is blocked by the blocking portion 72 of the locking member 70 and cannot be pivoted, and the outer handle 82 of the outer operating device 76 cannot be rotated, so that the latch 42 can not be displaced through the outer handle 82 of the outer operating device 76 to Unlatch position.

Regardless of whether the locking member 70 is in the locked position or the released position, as long as pressure is applied to the operating member 175 on the inner side of the door 20, the operating member 175 is pressed against the first sensing member 173, so that the first sensing member 173 outputs a signal-controlled electric drive. The device 153 is operated, the driving member 155 is pivoted by the release end 157 at an angle of the pressing rod 48 to the angle of the driving end 159 against the pressing rod 48, and the pressing rod 48 is pivoted by the pressing of the driving member 155, further The lever 48 is pressed against the push rod 46 to cause the push rod 46 to interlock with the tractor 44, so that the latch 42 is displaced from the upper latch position (as shown in FIG. 3) to the unlatching position (as shown in FIG. 9). .

Assuming that the locking member 70 is in the released position, the locking of the inner locking core 139 of the inner locking cylinder 137 is released using the correct key, and the inner locking member 139 is further rotated by the key to cause the inner dial 151 to press against the second of the transmission block 56. The end 60, such that the locking member 70 is pushed by the rocker arm 62 to be displaced from the release position to the locked position, the second sensing member 174 is pressed by the pressing portion 74 of the locking member 70, and the light-emitting device 193 of the inner operating device 92 generates a light source display. On the light transmissive cover 195.

When the lock member 70 is in the locked position, the lock state of the inner lock core 139 of the inner lock cylinder 137 is released or the lock state of the outer lock core 88 of the outer lock cylinder 86 is released, and the inner dial member 151 or the outer portion can be further operated. The dial member 90 presses against the first end 58 of the transmission block 56, causing the transmission block 56 to pivotally reset, while the rocker arm 62 interlocks the locking member 70 to be displaced from the locked position (as shown in FIG. 8) to the release position (eg, 3rd) 4, the pressing portion 74 of the locking member 70 releases the second sensing member 174, and the second sensing member 174 does not output a signal to the light emitting device 193, and the light emitting device 193 extinguishes the light source.

The inner operating device 92 of the present invention can determine whether the door lock 10 is set to the locked state or the unlocked state by the light generated by the light emitting device 193 or without generating bright light, so that it can be effectively solved by the inner operating device 92 that the door lock 10 cannot be determined. The problem is set to the locked state or the unlocked state.

In addition, the electronic design of the inner operating device 92 of the present invention greatly reduces the complexity of the mechanical structure and the number of parts, and can effectively reduce the manufacturing cost.

The basic teachings of this creation have been described, and many extensions and variations will be apparent to those of ordinary skill in the art. For example, the electric drive device 153 of the present invention may preferably be an electric motor. However, the electric drive device may also be an item other than an electric motor. For example, the electric drive device may be commercially available but not limited to commercially available ones. The solenoid valve, if the solenoid valve is used as the electric drive device, may not include the driving member 155, and the plunger 48 is pivoted by the solenoid valve energizing and non-energizing to drive the shaft to move the interlocking latch device 30, and the bolt can also be interlocked. The head 42 is displaced between the upper latch position and the unlatched position. Alternatively, the first sensing member 173 may be a device other than the pressure sensor, for example, the first sensor 173 may be a micro switch.

It should be noted that the inner operating device 92 can use the light emitting device 193 to generate the light source to indicate that the door lock 10 is in the locked state and the light emitting device 193 does not generate the light source to indicate that the door lock 10 is in the unlocked state. The light source of the color indicates the locked state or the unlocked state of the door lock 10. For example, when the door lock 10 is set to the locked state, the light source that generates the red light from the light-emitting device 193 is displayed on the transparent cover 195, and when the door lock 10 is set to the unlocked state, The light emitting device 193 produces a green light source that is displayed on the light transmissive cover 195. Alternatively, the light-emitting device 193 may be designed such that when the door lock 10 is set to the locked state, the light-emitting device 193 does not generate bright light, and when the door lock 10 is set to the unlocked state, the light-emitting device 193 generates bright light.

Alternatively, the door lock 10 can be combined with a different form of the outer operating device 76. For example, the outer operating device 76 can also be constructed of only one outer locking cylinder 86 mounted on the outer side 26 of the door 20 and a fixed handle. After the metal key unlocks the outer lock 88 of the outer lock cylinder 86, the latch is allowed to be operated using the outer lock cylinder 86 (e.g., the latch device uses the latch device disclosed in U.S. Patent No. 8,641,104). Displace to the unlatched position.
