Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to an oblique unlocking mechanism. Background Art

[0002] When an automobile seat backrest has functions such as an inclination angle or being laid down, a locking mechanism needs to be provided to lock the backrest when adjustment is not required. As Figure 1 shown, the existing locking and unlocking components are a vertical unlocking mechanism. By pressing the unlocking button 310, the body lock wire D is driven to rotate downward, and the body lock wire D slides out of the body locking groove to achieve unlocking. However, the unlocking direction of the handle of this structure is the vertical direction, which cannot meet the requirement of oblique unlocking under the sloping shoulder shape. When it comes to the sloping shoulder shape of an automobile seat backrest, as Figure 2 shown, the locking and unlocking can be achieved through a structure of oblique unlocking by a cable. This structure rotates the unlocking handle 320, and the unlocking handle 320 drives the cable 15 to unlock the backrest lock. However, since the cable 15 is a flexible part, it cannot be pre-assembled together with the unlocking handle 320, the cable 15 and the lock device 14 and then transported together. Therefore, the general assembly factory needs to install the unlocking handle 320, the cable 15 and the lock device 14 on the backrest respectively, which consumes working hours. In addition, the cable 15 has a high cost. Moreover, the cable 15 requires a large turning radius, occupying more installation space. And when the designed unlocking stroke is at the critical point and the layout space of the unlocking handle 320 is insufficient to provide a larger unlocking stroke, a regulator needs to be added to reduce the tolerance, increasing the cost again.

[0003] It can be seen that for a backrest with a sloping shoulder shape and requiring oblique unlocking, the existing vertical unlocking mechanism cannot meet the requirements, while the oblique unlocking mechanism with a cable has problems such as high cost, high installation working hours, and occupying space. Summary of the Utility Model

[0004] Aiming at the deficiencies existing in the above-mentioned prior art, the utility model provides an oblique unlocking mechanism, which solves the technical problem that in the prior art, for a backrest with a sloping shoulder shape and requiring oblique unlocking, the existing vertical unlocking mechanism cannot meet the requirements.

[0005] An oblique unlocking mechanism for a lock device of the utility model includes an unlocking switch configured to rotate between a first position and a second position. The lock device includes a lock hook, and the unlocking switch is used to drive the lock hook to rotate from a locked position to an unlocked position.

[0006] A first included angle is formed between the rotation plane of the unlocking switch and the rotation plane of the lock hook. The oblique unlocking mechanism further includes an adapter plate connected between the unlocking switch and the lock device.

[0007] A further improvement of the diagonal unlocking mechanism of the present utility model lies in that the adapter plate is rotatably connected to the unlocking switch. In response to the unlocking switch rotating from the first position to the second position, the adapter plate drives the locking hook to rotate from the locking position to the unlocking position.

[0008] A further improvement of the diagonal unlocking mechanism of the present utility model lies in that the adapter plate includes a horizontal plate and an inclined plate fixed to the horizontal plate. A second included angle is formed between the inclined plate and the horizontal plate, and the first included angle and the second included angle are complementary angles to each other.

[0009] A further improvement of the diagonal unlocking mechanism of the present utility model lies in that at least a part of the edge of the inclined plate extends towards the side of the horizontal plate to form a flanging.

[0010] A further improvement of the diagonal unlocking mechanism of the present utility model lies in that the diagonal unlocking mechanism further includes an unlocking wire. One end of the unlocking wire is fixedly connected to the horizontal plate, and the other end is rotatably connected to the locking device. The adapter plate drives the locking hook to rotate from the locking position to the unlocking position through the unlocking wire.

[0011] A further improvement of the diagonal unlocking mechanism of the present utility model lies in that one end of the unlocking wire forms a crossbar section. The crossbar section is arranged on the upper surface of the horizontal plate, and a cover plate for covering the crossbar section is provided on the horizontal plate to fixedly connect the unlocking wire to the horizontal plate.

[0012] A further improvement of the diagonal unlocking mechanism of the present utility model lies in that an opening groove is provided at the edge of the horizontal plate, and the unlocking wire passes through the opening groove to limit the unlocking wire.

[0013] A further improvement of the diagonal unlocking mechanism of the present utility model lies in that the diagonal unlocking mechanism further includes a housing. The unlocking switch is rotatably installed in the housing through a shaft pin, and a torsion spring is connected between the unlocking switch and the housing.

[0014] A further improvement of the diagonal unlocking mechanism of the present utility model lies in that the diagonal unlocking mechanism further includes a warning component installed in the housing. The warning component includes a fixed pin fixed to the housing and a warning block slidably installed on the fixed pin. When the unlocking switch rotates from the first position to the second position, the warning block is lifted.

[0015] A further improvement of the diagonal unlocking mechanism of the present utility model lies in that the warning component further includes a spring sleeved on the fixed pin. One end of the spring abuts against the warning block, and the other end of the spring abuts against the unlocking switch.

[0016] Compared with the prior art, the effects of the present utility model are positive and obvious. By means of the unlocking switch arranged at an angle and cooperating with the adapter plate, the present utility model solves the technical problem that in the prior art, for a backrest with a sloping shoulder shape and when oblique unlocking is required, the existing vertically unlocking mechanism cannot meet the requirements. The unlocking mechanism of the present utility model cancels the cable, saving the cable cost and space. In addition, the unlocking mechanism of the present utility model can be pre-assembled with the lock assembly and then installed on the backrest, saving the installation man-hours. Moreover, as an assembly, for a seat with an oblique unlocking requirement, the present unlocking mechanism only needs to change the shape of the handle or the backrest panel to match the new shape of the backrest, and without changing other structures, it can meet the oblique unlocking requirements within the range of 0 to 45° of the oblique angle.

Detailed implementation mode

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0043] As Figures 3 to 22 shown, the present invention provides an oblique unlocking mechanism, including an unlocking switch 3 configured to rotate between a first position and a second position. The locking device 14 includes a locking hook 144. The unlocking switch 3 is used to drive the locking hook 144 to rotate from a locked position to an unlocked position. As Figure 14 shown, a first included angle B is formed between the rotating plane S1 of the unlocking switch 3 and the rotating plane S2 of the locking hook 144. The rotating plane S1 of the unlocking switch 3 refers to a plane perpendicular to the rotating axis L1 of the unlocking switch 3, and the rotating plane S2 of the locking hook 144 refers to a plane perpendicular to the rotating axis L2 of the locking hook 144. The oblique unlocking mechanism further includes an adapter plate 7 connected between the unlocking switch 3 and the locking device 14. Specifically, as Figure 14 shown, the angle of the first included angle B is between 0 and 45°, which can meet the oblique unlocking requirement and adapt to the shape of the seat back with a sloping shoulder at the same time.

[0044] Furthermore, as Figure 11 shown, the adapter plate 7 is rotatably connected to the unlocking switch 3 through a bushing 5. Openings for the bushing 5 to pass through are provided on both the adapter plate 7 and the unlocking switch 3.

[0045] Preferably, the adapter plate 7 is rotatably connected to the unlocking switch 3. In response to the unlocking switch 3 rotating from the first position to the second position, the adapter plate 7 drives the locking hook 144 to rotate from the locking position to the unlocking position. The adapter plate 7 can transmit the movement of the unlocking switch 3 and apply this transmitted movement to the locking hook 144, thereby realizing the unlocking operation.

[0046] Preferably, as Figure 9 , 10 , 11, 15 and 16 show, the adapter plate 7 includes a horizontal plate 72 and an inclined plate 71 fixed to the horizontal plate 72. A second included angle C is formed between the inclined plate 71 and the horizontal plate 72, and the first included angle B and the second included angle C are complementary angles. Specifically, the inclined plate 71 is rotatably connected to the unlocking switch 3, and the horizontal plate 72 is connected to the locking hook 144. Thus, when pressing the unlocking switch 3, the locking hook 144 can be driven to unlock through the entire adapter plate 7, improving the convenience of unlocking. The inclined plate 71 and the horizontal plate 72 can be integrally formed or fixed by conventional fasteners. The angle of the second included angle C is between 0 and 45°.

[0047] Preferably, as Figure 9 , 10 , 11 and 16 show, at least a part of the edge of the inclined plate 71 extends towards the horizontal plate 72 side to form a flange 73. Since the unlocking switch 3 is inclined, when unlocking, the direction of the pressing force applied to the unlocking switch 3 is at an inclined angle, so the inclined plate 71 will receive a certain horizontal component force, which easily causes the inclination angle of the inclined plate 71 to change. The strength of the inclined plate 71 can be increased through the flange 73, thereby preventing the inclination angle of the inclined plate 71 from changing.

[0048] Preferably, as Figure 4 , 5 , 9, 10, 15, 16, 18, 20, 21 and 22 show, the oblique unlocking mechanism further includes an unlocking wire 8. One end of the unlocking wire 8 is fixedly connected to the horizontal plate 72, and the other end is rotatably connected to the locking device 14. The adapter plate 7 drives the locking hook 144 to rotate from the locking position to the unlocking position through the unlocking wire 8. Specifically, as Figure 23As shown, the structure of the lock device 14 has been disclosed in Chinese patent CN107428262B as a locking unit for a vehicle seat, which includes a locking pawl, which is mounted to be pivotable around a pivot axis between an open position and a closed position, and the locking pawl has a retaining profile for fixing a locking bolt to the closed position, and at least one claw-shaped member, which is mounted to be pivotable around the same pivot axis, wherein the claw-shaped member has a closing profile, through which the locking bolt acts, and the locking pawl can be pivoted from the open position to the closed position, wherein the locking pawl and the at least one claw-shaped member are parallel and offset in the axial direction and pivotally mounted on a first bearing pin, wherein the first bearing pin extends in the axial direction, and the surface of the cover of the locking pawl facing the locking bolt has a path having a vertex in the axial direction of the pivot axis, and the vertex is offset relative to the center of the width of the surface in the axial direction of the pivot axis. As shown in FIG. Figure 20 , 21 As shown in FIG. 22, the lock device 14 of the utility model includes a connecting plate 141, a first bearing pin 142, a second bearing pin 143, a lock hook 144, a driving element 145, a latch pawl 146 and a tension spring 147. The unlocking wire 8 is a component for unlocking the lock hook 144 of the transmission lock device 14, so that the entire oblique unlocking mechanism is an assembly, which saves installation space.

[0049] Preferably, Figure 9 , 10 , 11 and 16, a cross bar section is formed at one end of the unlocking wire 8, and the cross bar section is arranged on the upper surface of the cross plate 72. An opening groove 74 is arranged at the edge of the cross plate 72, and the opening direction of the opening groove 74 is roughly perpendicular to the direction of the rotation axis of the adapter plate 7. The unlocking wire 8 passes through the opening groove 74 to limit the unlocking wire 8. A cover plate 12 for covering the cross bar section is provided on the cross plate 72 to fix the unlocking wire 8 to the cross plate 72. The cross bar section can be hooked on the cross plate 72 and further fixed by the cover plate 12 to avoid detachment during use. A plurality of convex ribs 75 are also provided on the upper surface of the cross plate 72 so that the cross bar section can be in point contact with the cross plate 72 to reduce abnormal noise.

[0050] Preferably, Figures 3 to 8As shown, the diagonal unlocking mechanism further includes a housing 13. The unlocking switch 3 is fitted with the mounting hole 132 on the housing 13 through a rotating shaft 31, so that the unlocking switch 3 is rotatably mounted inside the housing 13, and the rotating shaft 31 is integrally formed with the unlocking switch 3. A torsion spring 6 is connected between the unlocking switch 3 and the housing 13. Specifically, a fixing block 10 is arranged axially on the unlocking switch 3. A rotating shaft pin 11 sequentially passes through the fixing block 10 and the rotating shaft 31 on the unlocking switch 3. A key groove 32 is provided on the rotating shaft 31, and a key shaft 101 adapted to the key groove 32 is provided on the fixing block 10, so that the fixing block 10 and the unlocking switch 3 rotate synchronously. The torsion spring 6 is connected between the fixing block 10 and the housing 13, and the torsion spring 6 can balance the force exerted by the unlocking switch 3 on the adapter plate 7. Further, at least one rubber pad 4 for preventing abnormal noise of the unlocking switch 3 is installed inside the housing 13. In this embodiment, the number of the rubber pads 4 is two, and the two rubber pads 4 are arranged at intervals inside the housing 13. The housing 13 is in the shape of a hollow box, and the side surface of the housing 13 allows the fixing block 10 and the adapter plate 7 to protrude. Preferably, as Figures 3 to 5 As shown, the diagonal unlocking mechanism further includes a warning component installed inside the housing 13. The warning component includes a fixing pin 22 fixed on the housing 13 and a warning block slidably mounted on the fixing pin 22. When the unlocking switch 3 rotates from the first position to the second position, the warning block is lifted. Specifically, the warning block includes a warning cover plate 1 and a cover plate connecting member 21. The warning cover plate 1 is red, so when the warning block is lifted, the warning cover plate 1 is extremely eye-catching, so as to achieve the warning effect.

[0051] Preferably, as Figures 3 to 5 , 16, 18 shown, the warning component further includes a spring 9 sleeved on the fixing pin 22. One end of the spring 9 abuts against the warning block 21, and the other end of the spring 9 abuts against the unlocking switch 3. Specifically, the unlocking switch 3 extends at a certain angle to form a clamping rod 133 for abutting against the lower end of the spring 9. The clamping rod 133 is clamped on both sides of the fixing pin. The cover plate connecting member 21 includes a housing fixed inside the housing 13 and a moving rod. A guiding groove 131 for guiding the movement of the warning cover plate 1 is fixed on the housing 13. The first end of the moving rod is vertically slidably sleeved on the fixing pin 22 and abuts against the upper end of the spring 9. The second end of the moving rod vertically slides through the housing, and a notch for the moving rod to pass through is provided on the housing. The warning cover plate 1 is vertically slidably mounted inside the housing, and the second end of the moving rod abuts against the bottom of the warning cover plate 1. Therefore, when the unlocking switch 3 is pressed, the unlocking switch 3 rotates around the rotating shaft pin 11, and at the same time drives the clamping rod 133 to lift upward, so that the spring 9 is compressed, and the elastic force of the spring 9 makes the moving rod slide upward, so as to drive the warning cover plate 1 to lift upward to achieve the warning effect.

[0052] Preferably, as Figure 12 and 13As shown, the lock device 14 and the unlocking switch 3 are arranged on the same side of the vehicle seat backrest, and the unlocking switch 3 is provided at the shoulder of the vehicle seat backrest. This arrangement can meet the requirements of oblique unlocking for backrests of various shapes, including those with sloping shoulders, and save installation space and facilitate installation.

[0053] When it is necessary to adjust the angle of the seat backrest or fold down the seat backrest, as Figures 16 to 19 shown, apply a force F to press the unlocking switch 3, causing the unlocking switch 3 to rotate around the pivot pin 11, and at the same time driving the clamping rod 133 to lift upward, thereby compressing the spring 9. The elastic force of the spring 9 causes the moving rod to slide upward, thereby driving the warning cover plate 1 to lift upward to achieve a warning effect. The unlocking switch 3 also drives the adapter plate 7 to rotate, and the rotating plate 7 drives the unlocking wire 8 to move and rotate, as Figures 20 to 22 shown, thereby opening the locking hook 144 of the lock device 14, enabling the vehicle body lock wire D in the locking hook 144 to be disengaged, and then the operation of adjusting the angle of the seat backrest or folding down the seat backrest can be performed.

[0054] The present utility model solves the technical problem in the prior art that for a backrest with a sloping shoulder shape and requiring oblique unlocking, the existing vertically unlocking mechanism cannot meet the requirements by cooperating the unlocking switch arranged at an angle with the adapter plate. The unlocking mechanism of the present utility model cancels the cable, saves the cable cost and space. In addition, the unlocking mechanism of the present utility model can be pre-assembled with the lock assembly and then installed on the backrest, saving installation man-hours. As a total assembly, for a seat requiring oblique unlocking, only the handle shape or the backrest panel needs to be changed to match the new shape of the backrest, and other structures do not need to be changed to meet the oblique unlocking requirements within the range of 0 to 45° of the oblique angle.

[0055] Parts not involved in the present utility model are the same as or can be implemented using the prior art. The above description is only a preferred embodiment of the present utility model and does not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art, without departing from the technical solution of the present utility model, can make some changes or modifications to the above-disclosed technical content to form an equivalent embodiment with equivalent changes. However, as long as it does not depart from the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
