Description

Technical Field

[0001] This utility model relates to a lock body assembly for an electronically controlled door lock, specifically, to a lock body assembly for a non-road machinery cockpit door lock, belonging to the field of non-road machinery cockpit technology. Background Technology

[0002] The door locks of non-road machinery cabs must ensure reliable door closure while also ensuring convenient door opening. With the rapid development of large-scale machinery technology and the advancement of electronic control and automation technology, non-road machinery is gradually placing greater emphasis on driving experience and automated control.

[0003] Traditional non-road mechanical door locks typically have only 1-2 unlocking methods, most commonly an internal mechanical wrench and an external key. In the complex operating environment of non-road machinery, this results in poor ease of operation.

[0004] Traditional non-road mechanical door locks sometimes have motion interference in the design of internal and external unlocking mechanisms. In a certain operating mode, the other operating end may be stuck or unable to reset, resulting in unsmooth operation or even malfunction.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This utility model addresses the shortcomings of the prior art by providing a lock body assembly for an electronically controlled door lock, which can solve the problems of the single and inconvenient unlocking method of traditional non-road mechanical door locks, and can also solve the problem of interference between internal and external unlocking linkages.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: An electric door lock body assembly includes an L-shaped lock housing. Inside the lock housing, a lock hook, a swing arm B, and a swing arm A are installed on one side and are connected in sequence. Inside the lock housing, an unlocking trigger A, a reverse torque tooth, and a pressure arm are installed on the other side and are connected in sequence. One side of the unlocking trigger A is provided with a groove for the free end of the swing arm A to enter. The size of the groove is larger than the size of the free end of the swing arm A.

[0008] Furthermore, the lock hook, swing arm B, and swing arm A are all hinged and installed inside the lock housing.

[0009] Furthermore, the bottom of the locking hook engages with the top of the swing arm B, and a spring is installed between the two. A lever is provided on the side of the swing arm B near the swing arm A.

[0010] Furthermore, the lock hook cooperates with the lock tongue, the lock tongue is fixedly installed on the door frame of the cab, and a lock tongue guard plate is installed on the lock tongue.

[0011] Furthermore, the inner side of the lock housing is provided with an unlocking mechanism B that swings synchronously with the swing arm A.

[0012] Furthermore, the unlocking trigger A, the reverse torque tooth, and the pressure arm are all hinged and installed inside the lock housing.

[0013] Furthermore, the unlocking trigger A is engaged with the reverse torque tooth, the top of the reverse torque tooth abuts against the pressure arm, and the side of the pressure arm is connected to the torsion spring.

[0014] Furthermore, a trigger steering pin is installed at the bottom of the unlocking trigger A, and two mounting holes are provided side by side on the trigger steering pin.

[0015] Furthermore, the side of the lock housing may also be equipped with an unlocking trigger C that is connected to the reverse torque teeth.

[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: By setting multiple unlocking triggers, each corresponding to a different unlocking channel, the problem of the single and inconvenient unlocking method of traditional non-road mechanical door locks can be solved. Through the ingenious slot design, unidirectional transmission is achieved. That is, the unlocking trigger A can drive the swing arm A, but the movement of the swing arm A will not drive the unlocking trigger A in turn. This fundamentally avoids motion interference between the internal and external operating mechanisms and ensures the independence of each unlocking channel.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0020] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown in the figure, the present invention provides a lock body assembly for an electric door lock, including an L-shaped lock housing 101. A lock hook 102, a swing arm B1011 and a swing arm A1010 are installed on one side of the interior of the lock housing 101 in sequence. An unlocking trigger A104, a reverse torque tooth 105 and a pressure arm 106 are installed on the other side of the interior of the lock housing 101 in sequence.

[0022] The locking hook 102, swing arm B1011, and swing arm A1010 are all hingedly installed inside the lock housing 101. The bottom of the locking hook 102 engages with the top of the swing arm B1011, and a spring is installed between them. A lever is provided on the side of the swing arm B1011 near the swing arm A1010. The swing arm A1010 drives the swing arm B1011 to swing through the lever, and the swing arm B1011 drives the locking hook 102 to swing.

[0023] The lock hook 102 cooperates with the lock tongue 108, which is fixedly installed on the door frame of the cab. A lock tongue guard plate 109 is installed on the lock tongue 108.

[0024] The inner side of the lock housing 101 is provided with an unlocking mechanism B107 that swings synchronously with the swing arm A1010. The unlocking mechanism B107 can be connected to the electric drive assembly, which provides power for the swinging of the unlocking mechanism B107.

[0025] The unlocking trigger A104, the reverse torque tooth 105, and the pressure arm 106 are all hinged and installed inside the lock housing 101. The unlocking trigger A104 is engaged with the reverse torque tooth 105, the top of the reverse torque tooth 105 abuts against the pressure arm 106, and the side of the pressure arm 106 is connected to a torsion spring, which provides pressure to the pressure arm 106. The unlocking trigger B107 and the unlocking trigger A104 need to overcome the pressure of the pressure arm 106 during the swinging process.

[0026] The bottom of the unlocking trigger A104 is equipped with a trigger steering pin 103. The trigger steering pin 103 has two mounting holes arranged side by side. The two mounting holes are used for threading and fixing the ends of the long pull cable and the short pull cable.

[0027] The unlocking trigger A104 has a slot on one side for the free end of the swing arm A1010 to enter, and the size of the slot is larger than the size of the free end of the swing arm A1010. During the swinging process, the unlocking trigger A104 can drive the swing arm A1010 to swing, while the swing arm A1010 will not drive the unlocking trigger A104 to swing, thus avoiding motion interference between the mechanisms and potential misoperation.

[0028] The side of the lock housing 101 may also be equipped with an unlocking trigger C1012 that is connected to the reverse torque tooth 105.

[0029] The specific working principle of this utility model is as follows: In this utility model, the unlocking trigger A104, unlocking trigger B107, or unlocking trigger C1012 can all rotate the lock hook 102 to release the hooked lock tongue 108 during the swinging process, thus completing the unlocking action.

[0030] The lock-unlocking machine B107 can be connected to an electric drive assembly, which provides power for the swing of the lock-unlocking machine B107, thereby unlocking the lock.

[0031] The bottom trigger pivot pin 103 of the unlocking trigger A104 can be connected to the door handle via a long pull cable. The door handle provides power for the swing of the unlocking trigger A104, thereby unlocking the door.

[0032] The bottom trigger steering pin 103 of the unlocking trigger A104 can be connected to the armrest button via a short pull cable. The armrest button provides power for the swing of the unlocking trigger A104, thereby unlocking the lock.

[0033] To unlock, simply press the unlocking trigger C1012.
