[0029] 1 to 5 , a door lock device proposed in the present application includes a main lock body 100, a transmission member 200, a lock tongue 300 and an unlocking mechanism. The main lock body 100 is provided with an inner cavity; the transmission member 200 is rotatably arranged in the inner cavity, and the transmission member 200 can rotate around a vertical axis. The transmission member 200 is provided with a first rotating part 210 and a second rotating part 220. The bottom of the inner cavity is provided with an inclined part 110, and the inclined part 110 is inclined upward along the rotation direction of the transmission member 200; one end of the lock tongue 300 is rotatably arranged in the inner cavity, and the lock tongue 300 is provided with a driven part 310. When the transmission member 200 rotates, the first rotating part 210 can push the driven part 310 to retract the lock tongue 300. At the same time, the second rotating part 220 can move along the inclined part 110 to move the transmission member 200 upward; the unlocking mechanism is connected to the transmission member 200 and can drive the transmission member 200 to rotate.

[0030] It can be understood that the door lock device provided in the embodiment of the present application is provided with a first rotating part 210 to cooperate with the driven part 310, and the unlocking mechanism drives the transmission member 200 to rotate to drive the first rotating part 210 to rotate, so that the first rotating part 210 pushes the driven part 310 to drive the lock tongue 300 to retract. At the same time, by providing a second rotating part 220 to cooperate with the inclined part 110, the transmission member 200 drives the second rotating part 220 to rotate when it rotates, so that the second rotating part 220 moves obliquely upward along the inclined part 110, thereby prompting the transmission member 200 to move upward, so that the transmission member 200 can move axially while rotating around the axial direction. This composite motion design breaks through the limitations of the single motion mode of the traditional transmission member 200, greatly expands the application scenarios of door locks, especially in complex door lock systems that need to simultaneously realize rotation and translation operations.

[0031] Furthermore, according to some embodiments of the present application, a second vertical rotating shaft is rotatably provided in the inner cavity, one end of the lock tongue 300 is rotatably connected to the second rotating shaft, and the lock tongue 300 is provided with a second torsion spring 360 for resetting.

[0032] Further, referring to Figures 1 to 4, according to some embodiments of the present application, the unlocking mechanism includes a toggle member 400 and a handle 500. The toggle member 400 is arranged on the side of the inner cavity opposite to the lock tongue 300. A first rotating shaft 410 is provided at one end of the toggle member 400 away from the lock tongue 300. The first rotating shaft 410 can be rotatably connected to the main lock body 100 and extend out of the inner cavity. One end of the handle 500 is connected to the end of the first rotating shaft 410. The toggle member 400 is provided with a toggle part 420, and the transmission member 200 is provided with an abutment part 230. When the toggle member 400 rotates, the toggle part 420 can push the abutment part 230 to rotate the transmission member 200. The toggle member 400 is provided with a first torsion spring 430 for resetting.

[0033] It is understood that when unlocking is required, the handle 500 is used to rotate the first rotating shaft 410, thereby driving the toggle member 400 to rotate, driving the toggle portion 420 to push the abutment portion 230, thereby driving the rotating member to rotate, and then driving the lock tongue 300 to retract, thereby unlocking. After releasing the handle 500, the toggle member 400 is reset under the elastic action of the first torsion spring 430.

[0034] Further, referring to Figures 2 to 3, according to some embodiments of the present application, the unlocking mechanism also includes a transmission rod 600, which is vertically arranged in the inner cavity, and the toggle portion 420 and the abutment portion 230 respectively abut against the two sides of the transmission rod 600. When the toggle member 400 rotates, the toggle portion 420 can push the transmission rod 600 so that the transmission rod 600 pushes the abutment portion 230. When the transmission member 200 moves upward, the abutment portion 230 maintains contact with the transmission rod 600.

[0035] It is understandable that in actual use, since the abutment portion 230 will move upward as the transmission member 200 rotates, there is a possibility that the abutment portion 230 will separate from the toggle portion 420, thereby affecting the performance of use. Therefore, the embodiment of the present application arranges a transmission rod 600 between the toggle portion 420 and the abutment portion 230 for transmission, and the abutment portion 230 maintains contact with the transmission rod 600, thereby ensuring the continuity and reliability of transmission during the entire unlocking process.

[0036] Further, referring to Figure 2, according to some embodiments of the present application, a notch is provided at the end of the abutment portion 230 that contacts the transmission rod 600, and the notch is adapted to the shape of the transmission rod 600, so that the transmission rod 600 is not easily loosened from the abutment portion 230, thereby ensuring the continuity and reliability of the transmission and reducing friction and wear.

[0037] Further, referring to Figure 2, according to some embodiments of the present application, abutment portions 230 are provided at the top and bottom of the transmission member 200. When the transmission member 200 moves upward, at least one abutment portion 230 maintains contact with the transmission rod 600, thereby improving the reliability and stability of the transmission and facilitating the force balance of the transmission rod 600.

[0038] Further, referring to Figures 2 to 5, according to some embodiments of the present application, the door lock device also includes a safety mechanism, the safety mechanism includes a blocking member 700 and a driving member, the blocking member 700 is arranged in the lock tongue 300 and can move up and down, the upper part of the blocking member 700 is provided with an upwardly extending blocking rod 710, the upper part of the lock tongue 300 is provided with a first through hole 320, the blocking rod 710 passes through the first through hole 320, and the blocking rod 710 abuts against the side of the first rotating part 210 close to the lock tongue 300, the driving member is arranged in the lock tongue 300, and when the lock tongue 300 retracts, the driving member can drive the blocking member 700 to move downward to retract the blocking rod 710.

[0039] It is understood that by providing a vertically movable blocking member 700 within the lock tongue 300, when the unlocking mechanism is not triggered, the blocking member 700 extends out of the first through hole 320 via the blocking rod 710 and abuts the side of the first rotating portion 210 near the lock tongue 300. As long as the first rotating portion 210 remains stationary, the lock tongue 300 cannot retract. When the unlocking mechanism is triggered, the transmission member 200 rotates to drive the first rotating portion 210 to rotate, and the first rotating portion 210 pushes the driven portion 310 to retract the lock tongue 300. During this process, the driving member drives the blocking member 700 downward to retract the blocking rod 710, so that the lock tongue 300 is no longer blocked during the retraction process and can be fully retracted. This achieves a reliable safety function through a simple structural principle, simplifies the process, and reduces manufacturing costs.

[0040] Further, referring to Figures 4 and 5, according to some embodiments of the present application, a downwardly extending guide rod 720 is provided at the lower portion of the blocking member 700, and a corresponding second through hole 330 is provided at the lower portion of the lock tongue 300, and the guide rod 720 is slidably provided in the second through hole 330.

[0041] It is understandable that the guide rod 720 can limit and guide the blocking member 700, thereby preventing the blocking member 700 from shaking left and right, and making the up and down movement of the blocking member 700 more stable and smooth.

[0042] Further, referring to Figures 4 and 5, according to some embodiments of the present application, the blocking member 700 is provided with a slide groove, and along the direction away from the first rotating part 210, the slide groove includes a first extension section 730 and a second extension section 740 connected in sequence, the width of the first extension section 730 along the up and down directions remains unchanged, and the width of the second extension section 740 along the up and down directions gradually increases in the direction away from the first extension section 730, and the driving member includes a lever 800, one end of the lever 800 is connected to the main lock body 100, and the other end of the lever 800 is passed through the slide groove, and when the lock tongue 300 is retracted, the lever 800 can move from the first extension section 730 to the second extension section 740.

[0043] It can be understood that the lever 800 is initially located in the first extension section 730 and remains stationary. The actual position can be determined according to actual conditions and is not specifically limited here. When the first rotating part 210 pushes the driven part 310 to retract the lock tongue 300, the blocking rod 710 will also move with the first rotating part 210 during this process, and while moving, it will retract into the first through hole 320 under the drive of the lever 800 until the first through hole 320 is fully retracted, so that the lock tongue 300 can be fully retracted. Then, by providing a first extension section 730 with a constant width, when the lever 800 moves inward along the first extension section 730 relative to the lock tongue 300, the blocking member 700 remains stationary relative to the lock tongue 300, and the blocking rod 710 does not gradually retract into the first through hole 320, but moves a certain distance along with the first rotating portion 210 until the lever 800 enters the second extension section 740 from the first extension section 730 relative to the lock tongue 300. As the width of the second extension section 740 gradually increases, the blocking member 700 gradually descends under the action of its own gravity, causing the blocking rod 710 to gradually retract into the first through hole 320, and finally completely retract into the first through hole 320 to leave the first rotating portion 210, so that the lock tongue 300 can be fully retracted. The above-mentioned structural manner can provide a buffer time for the lock tongue 300, and the lock tongue 300 will not feel loose when unlocking due to the blocking rod 710 retracting too quickly, thereby improving the user experience. On the other hand, by providing a buffer time, if the unlocking mechanism is interrupted during the buffer time, the lock tongue 300 can be quickly reset under the elastic action of the second torsion spring 360, reducing the movement of components, thereby reducing friction between components, and increasing service life by reducing loss.

[0044] Further, referring to Figures 3 to 5, according to some embodiments of the present application, a guide groove 340 is provided at the end of the lock tongue 300 away from the inner cavity, and the guide groove 340 extends in the horizontal direction. The guide groove 340 corresponds to the position of the slide groove, and the end of the lever 800 is sequentially passed through the slide groove and the guide groove 340. The width of the guide groove 340 in the up and down direction is equal to the width of the lever 800 in the up and down direction.

[0045] It is understandable that the guide groove 340 can guide and limit the lever 800, thereby preventing the lever 800 from shaking or deflecting during use, improving the reliability of the structure, and ensuring performance.

[0046] Further, referring to Figure 4, according to some embodiments of the present application, the end of the lever 800 away from the guide groove 340 can be rotatably connected to the second rotating shaft, and a third torsion spring 810 is provided. By utilizing the elastic action of the third torsion spring 810, the lever 800 can be forced to maintain the same position.

[0047] It is understood that, to adapt to different operating conditions, the lever 800 can be adjusted in position by rotating about the second rotation axis, and the position of the lever 800 can be fixed by adjusting the tension of the third torsion spring 810. Furthermore, if the lever 800 deviates due to contact with components during use, it can be reset by the third torsion spring 810. During maintenance, the user can also manually move the portion of the lever 800 extending out of the guide slot 340 to release the connection between the blocking rod 710 and the first rotating portion 210.

[0048] Further, referring to Figure 5, according to some embodiments of the present application, a limiting groove 350 is provided on the inner wall of the lock tongue 300 away from the inner cavity, and the end of the blocking member 700 away from the inner cavity is inserted into the limiting groove 350, thereby playing a role of limiting and fixing, which can prevent the blocking member 700 from shaking or offsetting during use, improve the reliability of the structure, and ensure the performance of use.

[0049] Further, referring to Figures 1 to 3, according to some embodiments of the present application, a square rod seat 900 is rotatably provided on the main lock body 100, and the square rod seat 900 is used to connect to the mechanical door lock. When the mechanical door lock is unlocked using a key, the mechanical door lock can drive the square rod seat 900 to rotate. The square rod seat 900 is provided with a driving part 910, and the driving part 910 can push the rotating part to rotate, thereby driving the lock tongue 300 to retract.

[0050] Furthermore, according to some embodiments of the present application, the transmission member 200 is provided with a fourth torsion spring for resetting.

[0051] Further, referring to Figure 6, according to some embodiments of the present application, the door lock device also includes a sky and earth lock 120, which is provided with a secondary lock tongue 121, and a connecting rod 130 is provided between the main lock body 100 and the sky and earth lock 120. The transmission member 200 is connected to the connecting rod 130 and can drive the connecting rod 130 to move. The connecting rod 130 is connected to the secondary lock tongue 121 through a mechanical structure. When the transmission member 200 moves, it can drive the connecting rod 130 to rotate around the axis, thereby triggering the mechanical structure and driving the secondary lock tongue 121 to retract, thereby realizing the synchronous unlocking of the main lock body 100 and the sky and earth lock 120.

[0052] Further, referring to Figure 6, according to some embodiments of the present application, the unlocking mechanism also includes a pressure rod 510, and the pressure rod 510 is connected to the end of the handle 500 away from the first rotating shaft 410. The pressure rod 510 is pressed down to rotate the handle 500, thereby driving the toggle member 400 to rotate through the first rotating shaft 410.

[0053] It should be noted that the mechanical structure between the connecting rod 130 and the auxiliary lock tongue 121 can adopt a connecting rod structure, a cam structure or other mechanical structures, or a combination of multiple mechanical structures. It can be determined according to actual conditions and is not specifically limited here.

[0054] It can be understood that in the embodiment of the present application, the transmission member 200 can rotate around the vertical axis and move along the axis at the same time, and can be equipped with different accessories to achieve different functions through compound movements to expand the application scenarios. The transmission member 200 and the connecting rod 130 can be connected by a spline connection or other structures to achieve that when the transmission member 200 moves, it only drives the connecting rod 130 to rotate without driving the connecting rod 130 to move axially.

[0055] It can be understood that in some embodiments, according to different usage requirements, the connection method between the connecting rod 130 and the transmission member 200 can be designed so that when the transmission member 200 moves, it can drive the connecting rod 130 to rotate while moving axially. For example, in some embodiments, the upper and lower ends of the transmission member 200 are provided with convex rods, and the end of the connecting rod 130 is provided with a connecting through hole that matches the convex rod. The convex rod is inserted into the connecting through hole to realize the connection between the transmission member 200 and the connecting rod 130. Furthermore, the convex rod can be a polygon, and the connecting through hole is correspondingly set to a polygonal hole, or the convex rod is provided with a convex pattern, and the connecting through hole is correspondingly provided with mutually matching grooves, thereby enhancing the reliability of the connection and ensuring the reliability of the transmission. It can also be other structural methods, which can be determined according to actual conditions, based on the principle of being able to realize the transmission between the transmission member 200 and the connecting rod 130, and will not be elaborated here.

[0056] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application.
