Description

Technical Field

[0001] The utility model relates to the technical field of screw rod end unlocking devices, in particular to a novel screw rod end unlocking device. Background Technique

[0002] An automatic vehicle door uses an automatic locking mechanism during operation, enabling the automatic door to be automatically locked after closing in place. In case of an emergency, an unlocking device needs to be operated to release the mechanical lock on the automatic door. For an automatic door with screw drive, the existing unlocking device is an intermediate unlocking device, which is an indirect unlocking device. The unlocking device toggles the nut to drive the screw rod to rotate for unlocking.

[0003] When the novel screw rod end unlocking device is in use, the following defects still exist: In the prior art, the unlocking mechanism is often directly related to the screw rod nut. Prolonged use or improper operation easily leads to nut wear, thereby affecting the accuracy and reliability of unlocking. In the prior art, the screw rod is prone to jumping under high-speed or heavy-load conditions, affecting the stability and safety of the equipment. In the prior art, the unlocking mechanism often has a complex structure, poor versatility, and is not convenient for maintenance and replacement. In the prior art, the unlocking operation is often cumbersome, with low unlocking efficiency. In the prior art, the unlocking or locking action is often not precise enough, prone to errors. In the prior art, the unlocking mechanism is often not stable enough in the unlocked state, easily affected by external interference. In the prior art, the unlocking mechanism often can only be operated locally, not convenient for remote control. In the prior art, the unlocking mechanism often cannot adapt to different working environments and operation requirements. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a novel screw rod end unlocking device is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: It includes a fixed seat, on which an S826 switch is provided, a rotating shaft is provided on the fixed seat, a wedge block is provided on the fixed seat, a runner is provided on the fixed seat, a detent is provided on the fixed seat, a rotating shaft is provided on the fixed seat, a wire drawing disc is provided on the fixed seat, a regulator bracket is provided on the S826 switch, an unlocking switch mounting plate is provided on the S826 switch, and a regulator device is provided on the regulator bracket.

[0006] As a further description of the above technical scheme:

[0007] The runner is connected to the rotating shaft, and the rotating shaft can be driven to rotate by operating the runner.

[0008] As a further description of the above technical scheme:

[0009] The wedge block is rotationally engaged with the rotating shaft and is used to achieve the unlocking or locking function when the rotating shaft rotates.

[0010] As a further description of the above technical solution:

[0011] The detent ball is arranged on the fixed seat and cooperates with the unlocking mechanism to maintain the unlocked state in the unlocked state.

[0012] As a further description of the above technical solution:

[0013] The wire drawing disc is connected to the unlocking mechanism. By pulling the wire on the wire drawing disc, the unlocking or locking of the unlocking device can be remotely controlled.

[0014] As a further description of the above technical solution:

[0015] The regulator device is installed on the S826 switch through the regulator bracket and is used to adjust the trigger threshold or sensitivity of the S826 switch.

[0016] As a further description of the above technical solution:

[0017] The wedge block has an inclined surface that matches the end of the lead screw. When the wedge block moves along the sliding groove, its inclined surface interacts with the inclined surface of the end of the lead screw, causing the lead screw to displace in the axial direction.

[0018] As a further description of the above technical solution:

[0019] The S826 switch is a microswitch, and its trigger point is located on the unlocking path of the end of the lead screw. When the end of the lead screw moves to the unlocking position, the S826 switch will be triggered.

[0020] The utility model has the following beneficial effects:

[0021] 1. In the utility model, unlocking is achieved by directly rotating the lead screw, and the unlocking is independent of the wear of the nut, solving the problem of lead screw jumping. By adopting the present invention, the middle position of the automatic locking mechanism can be supported by a bearing, thus solving the problem of lead screw jumping. The unlocking device is placed at the end of the locking mechanism, with a simple structure and high versatility. Through the direct connection between the rotating wheel and the rotating shaft, the user can directly operate the rotating wheel to drive the rotating shaft to rotate, achieving direct control of the end of the lead screw. This design not only simplifies the operation process but also improves the unlocking efficiency. The rotational cooperation design of the wedge block and the rotating shaft can accurately control the unlocking or locking action. When the rotating shaft rotates, the wedge block moves accordingly, thereby achieving effective locking or unlocking of the end of the lead screw.

[0022] 2. In the present utility model, the setting of the catch ensures that the unlocking mechanism can be stably maintained in the unlocked position in the unlocked state, which increases the safety and reliability of the device. The connection between the wire pulling disc and the unlocking mechanism allows the user to remotely control the unlocking or locking of the unlocking device by pulling the wire on the wire pulling disc. This design provides great convenience for the user, especially suitable for occasions where remote operation is required. The regulator device is installed on the S826 switch through the regulator bracket and can flexibly adjust the trigger threshold or sensitivity of the S826 switch. This design enables the device to adapt to different working environments and operation requirements, improving the applicability and flexibility of the device. The wedge block has an inclined surface that matches the end of the lead screw. When the wedge block moves along the chute, its inclined surface interacts with the inclined surface at the end of the lead screw, causing the lead screw to produce an accurate displacement in the axial direction. This design ensures the accuracy and reliability of the unlocking or locking action. The 826 switch, as a micro switch, has its trigger point on the unlocking path at the end of the lead screw. When the end of the lead screw moves to the unlocked position, it will accurately trigger the S826 switch, thus achieving precise control of the unlocking action. BRIEF DESCRIPTION OF THE DRAWINGS
