Description

Technical Field

[0001] The utility model relates to a motor lock. Background Art

[0002] A motor lock is an electronic lock that forms or releases a lock by rotating the shaft of a motor driven by electric current. The motor lock generally includes a housing, a shaft, and an action block. The action block is driven to rotate by the shaft, and then the lock is formed or released by the rotation of the action block and the housing. However, in the prior art, the motor lock often generates a rebound after the shaft drives the action block to move to the position for forming or releasing the lock. This can easily cause the action block to fail to reach or deviate from the predetermined position, so that the user can feel a stuck feeling when using it, which affects the user experience. The motor lock is also prone to damage itself, affecting the service life of the motor lock. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a motor lock with good user experience and greater stability.

[0004] To achieve the above-mentioned purpose, the utility model provides a motor lock, including a main body, the main body including a rotating shaft and an action block, the action block is rotatably arranged under the drive of the rotating shaft, the main body is provided with a mating end face opposite to the action block, the action block is provided with a sliding member, the sliding member can be slidably arranged along the mating end face under the drive of the action block, a limiting block is provided on the mating end face, and the limiting block can form an abutment limit with the sliding member when the action block rotates to a position corresponding to forming or releasing the lock.

[0005] The advantages of adopting the above technical solution are: a mating end face opposite to the action block is set in the main body, and a sliding part is set on the action block, so that the sliding part can slide on the mating end face as the action block rotates, and finally a limit block is set on the mating end face, so that the limit block can form an abutment limit with the sliding part when the action block rotates to the corresponding position for forming or releasing the lock, thereby avoiding the action block from rebounding after rotation and staying accurately in the predetermined position, ensuring the user experience, avoiding damage caused by position deviation, and making the product quality more stable.

[0006] The utility model can be further configured as follows: the limit block includes an abutting surface and a guiding surface, the abutting surface is used to abut and cooperate with the sliding member and is arranged perpendicularly to the end surface, and the guiding surface is gradually extended.

[0007] Through further configuration, an abutment surface and a guide surface are provided on the limit block, and the abutment surface perpendicular to the mating end surface abuts against the sliding member to ensure the limiting effect, and the setting of the guide surface enables the sliding member to slide smoothly after passing over the abutment surface during normal rotation.

[0008] The utility model can be further configured as follows: the matching end surface is provided with an abutment portion in contact with the sliding member, the abutment portion is extended along the movement track of the sliding member, and the limit block is arranged on the abutment portion.

[0009] By further configuring, an abutment portion extending along the movement trajectory of the sliding member is additionally configured on the mating end surface, and the limit block can be better configured to match the sliding member by adjusting the shape and surface of the abutment portion.

[0010] The utility model can be further configured as follows: a groove is provided on the action block, and the sliding member is elastically telescopically arranged in the groove.

[0011] Through further configuration, a groove is provided on the action block, and the sliding part can be elastically retracted and arranged in the groove. When crossing the abutment surface, the sliding part can overcome the elastic force and retract into the groove, and then smoothly pass through the abutment surface, thereby avoiding large wear after long-term use, which may lead to failure of the cooperation between the abutment surface and the sliding part.

[0012] The utility model can be further configured as follows: the sliding member includes a spring and a ball located in the groove portion, the diameter of the groove portion notch is smaller than the diameter of the ball, and the spring elastically presses the ball against the groove portion notch.

[0013] Through further configuration, the sliding member is configured to include a spring and a ball, and the diameter of the ball is made larger than the diameter of the groove notch to prevent it from slipping out. The spring presses the ball against the groove notch, thereby forming elastic expansion and contraction of the entire sliding member. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is a motor lock. Figure 1-5 As shown: it includes a main body 1, the main body 1 includes a rotating shaft 11 and an action block 12, the action block 12 is rotated under the drive of the rotating shaft, the main body 1 is provided with a matching end face 13 opposite to the action block 12, the action block 12 is provided with a sliding member 2, the sliding member 2 can be slid along the matching end face 13 under the drive of the action block, and a limit block 3 is provided on the matching end face 13, and the limit block 3 can form abutment limit with the sliding member 2 when the action block 12 rotates to the corresponding position of forming or releasing the lock. In this embodiment, a resistor 15 is also connected in parallel to the main body 1. Through the setting of the resistor 15, when the motor is blocked and the current becomes large, the resistor 15 can be used to shunt the current, so that when the main motor is blocked, the current passing through the motor is reduced compared to when the resistor 15 is not provided, and the output force is reduced to play the effect of controlling the rebound. On this basis, the action block and the limit block are coordinated to better avoid the occurrence of the rebound situation.
