Description

Technical Field

[0001] The present invention relates to the technical field of electronic locks, and in particular to a door lock handle and an electronic door lock and a door comprising the same. Background Art

[0002] An electronic lock is a comprehensive product that combines electronic technology, integrated circuit design, a large number of electronic components, and a variety of innovative identification technologies. In addition to being opened with keys, knobs, and switches, electronic locks can also be opened with light, electricity, magnetism, sound, and fingerprint commands. At present, common electronic locks are in locked mode during normal use, and each door opening requires fingerprint or password verification before the door can be opened. In addition, the indoor handle (installed indoors) does not have a switch, so it is troublesome to switch to channel mode (no fingerprint or password verification is required) and inconvenient to use. Usually, indoor fingerprint electronic locks are rarely used for opening and closing, and most application scenarios require channel mode. For this reason, we propose a door lock handle with a reset function that is commonly used in channel mode. Summary of the invention

[0031] Embodiments of the door lock handle, the electronic door lock and the door including the same according to the present invention will be described below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that the described embodiments may be modified in various ways or combinations thereof without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims. In addition, in this specification, the drawings are not drawn to scale and the same reference numerals represent the same parts.

[0032] Figure 1 is an exploded schematic diagram of a door lock handle according to an embodiment of the present invention; Figure 2 is a schematic diagram of an assembled state of a door lock handle according to an embodiment of the present invention; Figure 3a , Figure 3b is a schematic diagram of a door lock handle after a button is pressed according to an embodiment of the present invention; Figure 4a , Figure 4b Schematic diagram of a door lock handle push button popping out of a door lock handle according to an embodiment of the present invention. Figures 1 to 4b In this application, the indoor handle is installed on the indoor side of the door, and the outdoor handle is installed on the outdoor side of the door. The outdoor side is called the outside, and the indoor side is called the inside. The description of the "outside" and "inside" directions below is consistent with this.

[0033] like Figure 1 As shown, the door lock handle of this embodiment includes an indoor handle blocking cover 10, an indoor handle 1, a switch 2, a switch fixing plate 3, a switch fixing screw 4, a button sleeve 5, an indoor handle cover 6, a button cover 7, and a button driving cam pin 8.

[0034] The indoor handle 1 includes a rotatable column 11 and an extended handle portion 12. An indoor handle cover 10 is sleeved on the outer end of the column 11. The indoor handle cover 10 is a commonly used shape such as square or round, and is used to cover holes that penetrate the door body such as a lock core. A cavity is provided inside the column 11, and two or more installation threaded columns extending along the axial direction of the column 11 are fixed in the cavity. The installation threaded columns extend inwardly to the indoor handle cover 10 and extend outwardly for a certain length. There are internal threads in the installation threaded columns. Bolts passing through the installation threaded columns can fix the indoor handle 1 and the indoor handle cover 10 on the door.

[0035] A button guide column 13 is also fixed in the cavity. On the end surface of the button guide column 13 away from the indoor handle cover 10 (i.e., the end surface facing inward), a switch positioning groove 131, a switch wire hole 132, and a switch fixing screw hole 133 are provided. The switch wire hole 132 is used to pass the wire electrically connected to the switch 2, and the wire extends to the control circuit of the outdoor handle. The switch positioning groove has a shape that matches the switch, and is used to embed the switch 2 on the end surface of the button guide column 13. Figure 1 As shown, the switch 2 has a lever 21 on its side, and the lever 21 has two positions: a closed position and an open position. For example, when the lever 21 is pushed outward, it is closed, and when the lever 21 is pushed inward, it is open.

[0036] The switch fixing sheet 3 has a first through hole, and the switch fixing screw 4 passes through the first through hole and is screwed into the switch fixing screw hole, thereby fixing the switch 2 on the end surface of the button guide column 13 .

[0037] The button cover 5 is sleeved on the button guide column 13, and slides with the button guide column 13 in the axial direction, and can only move in the axial direction of the button guide column 13. A switch shift block (not shown) is connected inside the button cover 5, and the switch shift block is used to shift the switch 2 during the movement with the button cover 5, specifically, to shift the switch 2 to the closed position or the open position. As long as the switch shift block contacts the shift rod 21 of the switch 2 during the movement, the shift rod 21 can be shifted to change position, and the button cover 5 can be kept in the pressed state. Its form is similar to that of a toggle switch, and the specific structure will not be described in detail here.

[0038] A button-driven cam pin positioning hole is also provided in the cavity, through which the button-driven cam pin 8 passes, and the inner end of the button-driven cam pin 8 is close to the outer end of the button sleeve 5. A cam groove is provided on the indoor handle blocking cover 10, and the outer end of the button-driven cam pin 8 abuts against the cam groove. The button-driven cam pin 8 cooperates with the cam groove to move along the axial direction of the indoor handle, which is very convenient and easy to use. Specifically, as the indoor handle is pressed down and rotated, the button-driven cam pin 8 is also driven to rotate, and since the outer end of the button-driven cam pin 8 abuts against the cam groove, it will move axially along the contour of the cam groove, and the inner end of the button-driven cam pin 8 abuts against the button sleeve 5, pushing the button sleeve to the inner end. It should be noted that the indoor handle can also be set in the form of upward pressure, and its structure is basically the same as the above, as long as the button-driven cam pin 8 is driven to push the button sleeve to move during the rotation of the indoor handle.

[0039] The indoor handle cover 6 has the same shape as the handle portion 12, and one end thereof has a second through hole 61 for the button cover 5 to pass through and be fixed, and the button cover 7 is also fixedly connected to the button cover 5 through the second through hole 61. By pressing the button cover 7, the button cover 5 is pressed.

[0040] Normally, the lock body is in the channel mode, that is, the door can be opened by directly pushing the door without pressing the fingerprint or entering the password, nor pressing the door handle. At this time, the button sleeve 5 is in a state where the cam pin 8 is pushed inward by the button (such as Figure 4a , 4b As shown in FIG. 1 , the button driving cam pin 8 is located at the high point of the cam groove. When it is necessary to switch to the locking mode, it is only necessary to press the button cover 7 axially outward in the room (as shown in FIG. 1 ). Figure 3a , 3bAs shown in the figure, the button cover 7 drives the button sleeve 5 to move outward, and the button sleeve 5 pushes the button to drive the cam pin 8 to move outward along the cam groove, and the button sleeve 5 then drives the switch block to close, and the switch block 2 toggles the switch 2, so that the switch 2 generates a closing signal, and the switch 2 transmits the closing signal to the control circuit of the outdoor handle through the wire, and the control circuit controls the clutch to open and close, so that the door lock is in the locking mode. When outdoors, the fingerprint or password verification is required to open the door to enter the room, thereby realizing the function of convenient opening and closing indoors.

[0041] When it is necessary to switch to the channel mode, the handle portion 12 of the indoor handle 1 is pressed downward, and the indoor handle 1 drives the button-driven cam pin 8 to rotate together at a certain angle and then keep the pressed state. Since one end of the button-driven cam pin 8 is low against the cam groove, it will move inward along the axial direction of the indoor handle 1 under the action of the cam groove, thereby pushing the button sleeve 5 to move inward, and then the button sleeve drives the switch block to realize the opening action of the switch, so that the switch 2 generates an opening signal, and the switch 2 transmits the opening signal to the control circuit of the outdoor handle through the wire, and the control circuit can control the clutch to close, thereby realizing the function that the lock body is switched to the channel mode after the indoor handle 1 is pressed down indoors.

[0042] The present invention also provides an electronic door lock, comprising the door lock handle described above, and also comprising an outdoor handle for installation on the outdoor side of the door, wherein the outdoor handle is provided with a control circuit for controlling the opening and closing of the door, and the switch is electrically connected to the control circuit of the outdoor handle.

[0043] The present invention also provides a door, comprising the electronic door lock described above, wherein the door lock handle is installed on the indoor side of the door, the outdoor handle is installed on the outdoor side of the door, and the switch is electrically connected to the control circuit of the outdoor handle.

[0044] The present invention also provides a method for using a door lock handle, using the door lock handle to perform the following operations:

[0045] Pressing the button sleeve to toggle the switch to the closed position causes the control circuit of the outdoor handle to control the clutch to open and close, and the lock body on which the door lock handle is installed switches to the locked mode.

[0046] Pressing down the handle portion of the indoor handle causes the button sleeve to toggle the switch to the open position, so that the control circuit of the outdoor handle controls the clutch to close, and the lock body equipped with the door lock handle is switched to the channel mode.
