Description

Technical Field

[0001] This utility model relates to seat locks, and more particularly to an electrically controlled seat lock with mechanical unlocking. Background Technology

[0002] Chinese utility patent CN221298867U discloses an unlocking structure and a seat lock. The pull rope guide is fixed by means of snap-fit, and the pull rope moves along the pull rope guide to guide and protect the pull rope. However, the pull rope guide has the problem of falling off. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present utility model aims to provide an electrically controlled seat lock with mechanical unlocking, which is provided with a guide locking ear on the sealing plate and a rope end locking ear on the pull cable plate. The bottom of the guide locking ear groove is vertical and the pull rope presses the guide member and the guide locking ear together, which fully ensures the strong locking of the guide member and the guide locking ear.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This mechanically unlocked electrically controlled seat pad lock includes a sealing plate, a pull cable plate, and a buckle plate. The sealing plate cooperates with the buckle plate, and the buckle plate and the pull cable plate are rotatably arranged. The buckle plate is connected to the pull cable plate through a first return spring. The pull cable plate is equipped with a driving block, which is arranged to move left and right. The pull cable plate rotates between an unlocked state and a locked state. The pull cable plate is provided with a rope end locking ear, and the sealing plate is provided with a guide locking ear. The rope end locking ear and the guide locking ear are arranged sequentially in the left and right direction. The sealing plate is provided with an upward-facing limiting groove. The bottom of the grooves of the rope end locking ear and the guide locking ear are vertical and opposite in orientation. When the pull cable plate is in the locked state, pulling the rope presses the guide member and the guide locking ear together.

[0005] In this design, the grooves of the rope end clip and the guide clip face vertically and in opposite directions. When the cable plate is locked, the rope presses the guide component and the guide clip together, and the rope end and the rope end clip together, ensuring the stability of the rope installation.

[0006] Preferably, when the cable plate is in the locked state, the pull rope is located at point A at the rope end locking lug and at point B at the guide locking lug, with a height difference between points A and B.

[0007] In this scheme, the height difference causes the pull rope to tilt, and the pull rope tension will generate a vertical component force. The vertical components force at points A and B are opposite, which cooperate with the bottom of the corresponding slot.

[0008] Preferably, point A is higher than point B, and the bottom of the slot of the guide ear faces downward.

[0009] In this scheme, the vertical component of the rope at point A points downwards, and the vertical component at point B points upwards.

[0010] Preferably, point A is lower than point B, and the bottom of the slot of the guide ear faces upward.

[0011] In this scheme, the vertical component of the rope at point A points upwards, and the vertical component at point B points downwards.

[0012] Preferably, the drive block is connected to the motor via a transmission assembly, which includes a first end face gear and a second end face gear that mesh with each other, and the rotation axis of the first end face gear is consistent with the rotation axis of the second end face gear.

[0013] In this scheme, after the drive block moves into place, the first end face gear and the second end face gear repeatedly engage and disengage to avoid stalling.

[0014] Preferably, the transmission assembly further includes a transmission block that cooperates with the drive block. The drive block has a first inclined surface, and the transmission block has a second inclined surface. The transmission block is rotatably configured to define the area between the first inclined surface and the second inclined surface as the inner side. The outer side of the transmission block is provided with a first end face gear, and the second end face gear is connected to the motor for transmission. The outer side of the drive block is provided with a second return spring.

[0015] In this scheme, after the drive block moves into place, the motor continues to rotate. The first end face gear remains stationary with the drive block, while the second end face gear rotates with the motor. The second return spring keeps the first end face gear and the second end face gear connected, and the first end face gear and the second end face gear continuously engage and disengage.

[0016] Preferably, the drive block has a mounting groove on its outer side, the transmission block has a mounting shaft extending into the mounting groove on its inner side, the bottom of the mounting groove has a through hole for the mounting shaft to pass through, and the second return spring is sleeved on the mounting shaft.

[0017] In this design, the mounting shaft guides the extension and retraction of the second return spring.

[0018] Preferably, the assembly also includes a housing, and the transmission assembly further includes a first gear and a second gear. The drive block is provided with a rack, and the housing has an opening for the drive block to be exposed. A fixed shaft is disposed inside the housing and extends in the front-rear direction. The first gear, the first end face gear, the second end face gear, the second gear, and the second return spring are sequentially sleeved on the fixed shaft. The first gear and the second gear are respectively connected to the drive block and the motor for transmission. The first end face gear and the second end face gear are respectively connected to the first gear and the second gear. The drive block or the cable plate is provided with a baffle.

[0019] In this scheme, after the drive block moves into place, the motor continues to rotate. Because of the baffle, the first gear stays stationary with the drive block, while the second gear rotates with the motor. The second gear overcomes the elastic force of the second reset spring and undergoes axial displacement. The first end face gear and the second end face gear continuously engage and disengage, and the housing enables the first gear to remain stationary in the axial direction.

[0020] The beneficial effects of this utility model are as follows: the grooves of the rope end catch ear and the guide catch ear are vertically oriented and opposite in direction. When the cable plate is in the locked state, the pull rope presses the guide component against the guide catch ear and the rope end against the rope end catch ear, ensuring the stability of the pull rope installation. The height difference causes the pull rope to tilt, and the pull rope tension will generate a vertical component force. The vertical components at points A and B are opposite, which cooperate with the bottom of the corresponding catch groove. Therefore, this utility model has substantial features and progress compared with the prior art. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the implementation of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0035] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0036] See appendix Figure 1 , 10 In one embodiment of this invention, an electrically controlled seat lock with mechanical unlocking includes a guide latch 7 located at point B 29, point A 28 being lower than point B 29, and the bottom of the slot 9 of the guide latch 7 facing upwards.

[0037] In this embodiment, the guide member 26 is engaged with the guide latch ear 7, and the end of the pull rope 27 is engaged with the guide latch ear 7. The guide member 26 allows the pull rope 27 to pass through. When the cable plate 2 is in the locked state, point A 28 is lower than point B 29, and the pull rope 27 is tilted. The pull rope 27 has a vertical component force at both points A 28 and B 29. The vertical component force presses the end of the pull rope 27, the guide member 26 and the corresponding groove bottom tightly. The locked state is the normal state, so that the pressing force continues to act.

[0038] In other alternative implementations, point A 28 is higher than point B 29, and the bottom of the slot 9 of the guide ear 7 faces downward.

[0039] See appendix Figure 2-5 The drive block 5 is connected to the motor 11 via a transmission assembly 10. The transmission assembly 10 includes a first end face gear 12 and a second end face gear 13 that mesh with each other. The rotation axis of the first end face gear 12 is consistent with the rotation axis of the second end face gear 13. The transmission assembly 10 also includes a transmission block 14 that cooperates with the drive block 5. The drive block 5 has a first inclined surface 15, and the transmission block 14 has a second inclined surface 16. The transmission block 14 is rotatably set, defining the area between the first inclined surface 15 and the second inclined surface 16 as the inner side. The first end face gear 12 is provided on the outer side of the transmission block 14, and the second end face gear 13 is connected to the motor 11. A second return spring 17 is provided on the outer side of the drive block 5. A mounting groove 18 is provided on the outer side of the drive block 5, and a mounting shaft 19 extending into the mounting groove 18 is provided on the inner side of the transmission block 14. A through hole 20 is provided at the bottom of the mounting groove 18 for the mounting shaft 19 to pass through. The second return spring 17 is sleeved on the mounting shaft 19.

[0040] In this embodiment, the motor 11 drives the second end face gear 13 to rotate, and the first end face gear 12 meshing with the second end face gear 13 drives the transmission block 14 to rotate. The second inclined surface 16 rotates, while the first inclined surface 15 remains stationary. The contact position between the protrusion of the driving block 5 and the second inclined surface 16 changes, and the driving block 5 moves to the right relative to the transmission block 14. The driving block 5 pushes the cable plate 2 to rotate through the driving part, and the cable plate 2 pulls the buckle plate 3 to rotate through the first return spring 25. The buckle plate 3 leaves the limiting groove 8 to complete the unlocking. When locked, the driving block 5 moves to the left relative to the transmission block 14, and the cable plate 2 and the buckle plate 3 are reset by the elastic force of the first return spring 25.

[0041] The output shaft of motor 11 is connected to the rotating block, and the rotating block is engaged with the second end face gear 13. The first inclined surface 15 and the second inclined surface 16 are inclined relative to each other in the left and right directions and are respectively arranged to form grooves and protrusions along the circumference. During the rotation of the transmission block 14, the protrusion of the drive block 5 leaves or enters the groove along the second inclined surface 16, so that the drive block 5 moves left and right relative to the transmission block 14. Alternatively, the protrusion of the transmission block 14 can move along the first inclined surface 15. The second return spring 17 keeps the first end face gear 12 and the second end face gear 13 in contact. After the drive block 5 moves to the right, it repeatedly engages and disengages to avoid jamming. It can limit the rightward movement of the drive block 5, and can also limit the swing of the cable plate 2 to achieve the limit of the drive block 5.

[0042] See appendix Figure 6-9In another embodiment, a housing 21 is also included. The transmission assembly 10 further includes a first gear 22 and a second gear 23. The drive block 5 is provided with a rack 24. The housing 21 has an opening for the drive block 5 to be exposed. The fixed shaft 4 is disposed in the housing 21 and extends in the front-rear direction. The first gear 22, the first end face gear 12, the second end face gear 13, the second gear 23, and the second return spring 17 are sequentially sleeved on the fixed shaft 4. The first gear 22 and the second gear 23 are respectively connected to the drive block 5 and the motor 11 for transmission. The first end face gear 12 and the second end face gear 13 are respectively connected to the first gear 22 and the second gear 23. The drive block 5 or the cable plate 2 is provided with a baffle.

[0043] In this embodiment, when unlocking, the motor 11 drives the second gear 23 and the second end face gear 13 to rotate. The second end face gear 13 drives the first end face gear 12 and the first gear 22 to rotate. The first gear 22 drives the drive block 5 to move to the right. The drive block 5 abuts against the cable plate 2, causing the cable plate 2 to rotate. The cable plate 2 drives the buckle plate 3 to rotate through the first reset spring 25. The buckle plate 3's hook leaves the limit groove 8, completing the unlocking. When locking, the motor 11 simply reverses.

[0044] The above description represents the preferred embodiment of this utility model. It should be noted that the scope of protection of this utility model is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in this utility model, and these can also be considered as part of the scope of protection of this utility model.
