Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a seat armrest, a seat assembly and a vehicle. Background Art

[0002] As competition in the vehicle market becomes increasingly fierce, the functions of vehicle seat armrests are becoming more and more numerous. During use, the seat armrests are usually constantly reversed. Therefore, in order to improve the stability of the seat armrests, locking components are usually provided on the seat armrests.

[0003] In the related art, an unlocking rope and a fixed bracket are provided in the seat armrest of the vehicle. The unlocking rope is used to transmit the traction force of the driving member to the locking assembly to change the locking state of the locking assembly. The fixed bracket is connected to the side plate of the seat armrest by welding, and can be passed through by the unlocking rope to change the traction direction of the unlocking rope.

[0004] However, the above-mentioned fixing bracket and side plate need to be processed using different molds respectively and then welded, which will make the manufacturing and installation process of the fixing bracket and the side plate more complicated, thereby affecting the manufacturing efficiency of the seat armrest. Utility Model Content

[0005] The present application provides a seat armrest, a seat assembly and a vehicle, so as to at least solve the technical problem of low manufacturing efficiency of seat armrests in the related art. The technical solution of the present application is as follows:

[0006] According to the first aspect of the present application, there is provided a seat armrest, comprising a guard plate and a locking assembly, wherein the guard plate is used to be connected to a seat and can rotate relative to the seat. The locking assembly may include a locking member and an unlocking pull rope, wherein the locking member is connected to the guard plate and can move relative to the guard plate and is used to lock the guard plate on the seat, and the unlocking pull rope is connected to the locking member and can drive the locking member to move, thereby releasing the locking member from locking the guard plate. Part of the guard plate is bent toward the unlocking pull rope to form a limiting portion, and the limiting portion is provided with a limiting hole, and the unlocking pull rope passes through the limiting hole.

[0007] According to the above technical means, after the seat armrest is flipped to the required position, the guard plate can be locked on the seat by the locking assembly, thereby locking the seat armrest to prevent the seat armrest from shaking. When the seat armrest needs to be flipped, the seat armrest needs to be unlocked, specifically, by pulling the unlocking pull cord so that the unlocking pull cord drives the locking member to move, so that the locking member releases the lock on the guard plate to unlock the seat armrest.

[0008] When the unlocking rope pulls the locking piece to move, the unlocking rope can be limited by passing the unlocking rope through the limiting hole on the limiting part of the guard plate to prevent the unlocking rope from deviating and affecting unlocking.

[0009] Among them, part of the guard plate is bent toward the unlocking rope so that the bent part can form a limiting portion. The limiting portion can be formed while processing the guard plate, that is, a set of molds is used to manufacture the guard plate with the limiting portion, thereby reducing the number of molds and the processing steps when manufacturing the seat armrest; and, the limiting portion is a part of the guard plate, and the step of welding the limiting portion can be omitted in the process of manufacturing the seat armrest. Therefore, the manufacturing process of the seat armrest can be simplified and the manufacturing efficiency of the seat armrest can be improved.

[0010] In a possible implementation, the guard plate includes a first portion and a second portion of an integral structure, the second portion surrounds the first portion, and the first portion is bent toward the unlocking pull rope to form a limiting portion.

[0011] According to the above technical means, the first part is the middle area of ​​the guard plate. After the first part is bent, a through hole (i.e., a vacant area) will be formed at the original position of the first part before it is bent, and a limiting part is formed after the first part is bent. In this way, the material of the seat armrest can be saved and the weight of the seat armrest can be reduced.

[0012] In a possible implementation, the axial direction of the limiting hole may be consistent with a first direction, wherein the first direction is a moving direction of the unlocking rope when the locking member releases the lock on the guard plate.

[0013] According to the above technical means, the resistance of the unlocking pull rope during movement can be reduced, making it easier for the user to unlock.

[0014] In a possible implementation manner, the limiting hole penetrates to a side surface of the first part away from the second part.

[0015] According to the above technical means, it is helpful to place the unlocking pull rope in the limiting hole.

[0016] In a possible implementation, the maximum size of the gap of the limiting hole is smaller than the radial size of the unlocking rope, and the unlocking rope can enter the limiting hole through the gap of the limiting hole, wherein the gap of the limiting hole is located on a side surface of the first part away from the second part.

[0017] According to the above technical means, it is convenient to install the unlocking pull rope into the limiting hole, and it can also prevent the unlocking pull rope from exiting from the gap of the limiting hole, thereby improving the limiting effect.

[0018] In a possible implementation, the locking assembly may further include a harness tube, the harness tube is engaged with the limiting hole, and the unlocking pull rope passes through the harness tube.

[0019] According to the above technical means, on the one hand, the wiring harness drum can protect the unlocking pull rope to prevent the unlocking pull rope from breaking due to reciprocating friction with the limiting part during the unlocking process; on the other hand, the wiring harness drum can improve the limiting effect of the unlocking pull rope and reduce the radial shaking of the unlocking pull rope during movement.

[0020] In a possible embodiment, the seat armrest may further include a first connecting shaft, the guard plate is rotatably connected to the first connecting shaft, the locking member may include an active locking member, a driven locking member and a locking control member, the active locking member is connected to the first connecting shaft, the driven locking member is located on one side of the active locking member, the driven locking member is rotatably connected to the guard plate, and can be pressed against the active locking member, the locking control member is provided on the guard plate and connected to the unlocking pull rope, and can move between a first position and a second position, during the movement of the locking control member from the second position to the first position, it can contact the driven locking member and push the driven locking member to press against the active locking member; when the locking control member moves to the first position, the locking control member presses against the driven locking member, and the driven locking member presses against the active locking member, and when the locking control member is located in the second position, the locking control member is separated from the driven locking member so that the active locking member releases the pressure on the driven locking member.

[0021] According to the above-mentioned technical means, when there is no need to adjust the seat armrest, the locking control member can be moved from the second position to the first position to push the driven locking member to press against the active locking member, so that the active locking member generates resistance to the driven locking member to avoid the driven locking member from rotating relative to the active locking member, thereby avoiding the guard plate assembly from rotating relative to the first connecting shaft, that is, locking the guard plate assembly to improve the stability of the seat armrest.

[0022] When the seat armrest needs to be unlocked, the locking control part and the driven locking part can be separated first to reserve rotation space for the driven locking part. The active locking part can be rotated relative to the driven locking part, so that the guard plate rotatably connected to the driven locking part can be rotated around the first connecting axis, thereby completing the unlocking process of the seat armrest.

[0023] In a possible embodiment, the seat armrest may also include a driving member and a connecting plate, wherein the driving member is rotatably connected to the connecting plate and is used to drive the locking control member to move from the second position to the first position. The driving member is provided with a driving end and a driven end arranged at intervals around the rotation axis of the driving member, the driving end is connected to the operating rod, and the driven end is connected to the other end of the unlocking rope, and the opposite ends of the connecting plate are respectively connected to the two guard plates.

[0024] According to the above-mentioned technical means, the user pulls the operating lever to make the driving end of the driving member rotate relative to the guard plate, and at the same time the driven end of the driving member also rotates accordingly, and drives the connecting member connected to the driven end to move. The movement of the connecting member can pull the locking control member, so that the locking control member can move from the second position to the first position. A lever is formed between the operating lever and the driving member, so that the user can save more effort during the switching process.

[0025] According to a second aspect of the present application, a seat assembly is also provided, the seat assembly comprising the above-mentioned seat armrest.

[0026] According to a third aspect of the present application, a vehicle is also provided, the vehicle comprising the above-mentioned seat assembly.

[0027] Therefore, the above technical features of the present application have the following beneficial effects:

[0028] (1) The present application can use a set of molds to produce a guard plate with a limiting portion, thereby reducing the number of molds and the processing steps when producing the seat armrest; and, the limiting portion is part of the guard plate, and the step of welding the limiting portion can be omitted in the process of supporting the seat armrest, thereby simplifying the production process of the seat armrest and improving the production efficiency of the seat armrest.

[0029] (2) The present application can utilize a partial area of ​​the guard plate itself to form a limiting portion. A through hole (i.e., a vacant area) is formed at the original position of the first portion before it is bent, and the limiting portion is formed after the first portion is bent, thereby saving material for the seat armrest and reducing the weight of the seat armrest.

[0030] (3) The resistance of the unlocking rope during movement can be reduced, making it easier for the user to unlock the door.

[0031] (4) The present application can not only facilitate the installation of the unlocking pull rope into the limiting hole, but also prevent the unlocking pull rope from exiting from the notch of the limiting hole, thereby improving the limiting effect.

[0032] (5) On the one hand, the harness drum can protect the unlocking pull rope and prevent the unlocking pull rope from breaking due to reciprocating friction with the limiting part during the unlocking process. On the other hand, the harness drum can improve the limiting effect of the unlocking pull rope and reduce the radial shaking of the unlocking pull rope during the movement.

[0033] (6) The seat armrest can be stably locked by the active locking member, the driven locking member and the locking control member.

[0034] (7) The rotation of the driving member under the action of the operating rod drives the unlocking pull rope to drive the locking control member to move, thereby unlocking the seat armrest in a labor-saving and convenient manner.

[0035] (8) The driving force can be transmitted to the two locking control members on both sides of the first connecting shaft at the same time, so that the position switching states of the locking control members remain consistent.

[0036] It should be noted that the technical effects brought about by any implementation method in the second aspect to the third aspect can refer to the technical effects brought about by the corresponding implementation method in the first aspect, and will not be repeated here.

[0055] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0056] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0057] Figure 1 A schematic diagram showing the structure of a seat handle of the related art is shown. Figure 1 The handle guard 11 is connected to the fixing bracket 12 by bolts 13 or welding. One end of the pull rope 14 is connected to the power mechanism 15, and the other end passes through the fixing bracket 12 and is connected to the locking mechanism 16. The power mechanism 15 can control the movement of the locking mechanism 16 through the pull rope 14, thereby unlocking the seat handle 1. The through hole in the fixing bracket 12 can limit the pull rope 14 so that the traction force generated by the power mechanism 15 can be stably transmitted. It can be understood that due to the addition of the fixing bracket 12, the weight of the seat handle 1 will also increase, and the material cost is relatively high. At the same time, the welding or screwing method also increases the workload during the assembly process and reduces the assembly efficiency.

[0058] Based on this, the present application provides a seat armrest that can effectively improve the assembly efficiency of the seat armrest.

[0059] Figure 2One of the structural schematic diagrams of the chair armrest provided in one embodiment of the present application is shown. Figure 3 FIG. 1 shows one of the structural schematic diagrams of the guard plate provided in one embodiment of the present application, and FIG. Figure 2 and Figure 3 The seat armrest 2 provided in the present application may include a guard plate 21 and a locking assembly 22. The guard plate 21 is used to be connected to the seat and can rotate relative to the seat. The locking assembly 22 may include a locking member 221 and an unlocking pull rope 222. The locking member 221 is connected to the guard plate 21 and can move relative to the guard plate 21 to lock the guard plate 21 on the seat. The unlocking pull rope 222 is connected to the locking member 221 and can drive the locking member 221 to move, thereby releasing the locking member 221 from locking the guard plate 21.

[0060] After the armrest 2 is flipped to a desired position, the guard plate 21 can be locked to the seat by the locking assembly 22, thereby locking the armrest 2 to prevent the armrest 2 from shaking. When the armrest 2 needs to be flipped, the armrest 2 needs to be unlocked, specifically, by pulling the unlocking pull cord 222, so that the unlocking pull cord 222 drives the locking member 221 to move, so that the locking member 221 releases the locking of the guard plate 21, thereby unlocking the armrest 2.

[0061] When the unlocking rope 222 pulls the locking member 221 to move, the unlocking rope 222 can be limited by the limiting hole 212 on the limiting portion 211 of the guard plate 21 to prevent the unlocking rope 222 from deviating and affecting unlocking.

[0062] Among them, by bending part of the guard plate 21 toward the unlocking pull rope 222 so that the bent part can form a limiting portion 211, the limiting portion 211 can be formed while processing the guard plate 21, that is, a set of molds is used to manufacture the guard plate 21 with the limiting portion 211, thereby reducing the number of molds and the processing steps when manufacturing the seat armrest 2; and, the limiting portion 211 is a part of the guard plate 21, and the step of welding the limiting portion 211 can be omitted in the process of manufacturing the seat armrest 2, thereby simplifying the manufacturing process of the seat armrest 2 and improving the manufacturing efficiency of the seat armrest 2.

[0063] Figure 4 The second structural schematic diagram of the guard plate provided by an embodiment of the present application is shown. In some embodiments of the present application, the guard plate 21 includes a first part 214 and a second part 215 of an integral structure. The second part 215 surrounds the first part 214, and the first part 214 is bent toward the unlocking pull rope 222 to form a limiting portion 211.

[0064] It should be noted that the first part 214 can be bent toward the unlocking pull rope 222 along the first direction F1, and can also be bent toward the unlocking pull rope 222 along the second direction F2. As long as it is located on the moving path of the unlocking pull rope 222, the unlocking pull rope 222 can be stably limited. The area of ​​the first part 214 on the guard plate 21 is the area of ​​the vacant area 213 (the vacant area is a through hole) formed after bending.

[0065] It should also be noted that the first portion 214 may be rectangular, circular, or polygonal, etc., and is not limited to Figure 4 The structure shown.

[0066] In the specific processing process, the guard plate 21 can be first cut according to the outline of the first part 214, and only the bending edge L is retained without cutting, and the other edges are cut, and then the limiting hole 212 is punched out in the first part 214. Finally, the first part 214 is bent with the bending edge L as the rotation axis to form the limiting part 211 in the present application.

[0067] That is to say, part of the guard plate 21 itself can be bent, and the bent part can form a limiting portion 211, so as to limit the unlocking pull rope 222, replacing the fixed bracket 12 in the related art.

[0068] It can be understood that, since the limiting portion 211 in the present application is formed by bending the first portion 214 in the middle area of ​​the guard plate 21, after the first portion 214 is bent, a through hole (i.e., the vacant area 213) will be formed at the original position of the first portion 214 before the bending, and the limiting portion 211 is formed after the first portion 214 is bent, and in the related art, the guard plate 21 and the fixed bracket 12 are connected by welding or bolts, and the materials of the guard plate 21 and the fixed bracket in the contact part overlap. Therefore, compared with the solution of the related art, the present application can reduce the material area of ​​the contact part of the guard plate 21 and the fixed bracket by twice.

[0069] In this way, on the one hand, the present application can save the use of materials, thereby effectively reducing the weight of the seat armrest 2 and reducing material costs. On the other hand, since the guard plate 21 and the limiting portion 211 in the present application are integrated, it is no longer necessary to fix the guard plate 21 and the fixed bracket in the original solution together through welding or bolts. Therefore, the present application can also reduce the workload in the assembly process, thereby improving assembly efficiency.

[0070] In some embodiments of the present application, the axial direction of the limiting hole 212 may be consistent with the first direction F1, wherein the first direction F1 is the moving direction of the unlocking rope 222 when the locking member 221 releases the lock on the guard plate 21.

[0071] In this way, when the unlocking pull rope 222 is pulled to unlock the guard plate 21, the moving direction of the unlocking pull rope 222 can be consistent with the force direction, thereby reducing the resistance of the unlocking pull rope 222 during movement, making it easier for the user to unlock.

[0072] In some embodiments of the present application, the limiting hole 212 penetrates to a side surface of the first portion 214 away from the second portion 215 , so that the unlocking pull rope 222 can be conveniently installed in the limiting hole 212 along the direction of the bent first portion 214 pointing to the second portion 215 .

[0073] In some embodiments of the present application, the maximum size of the gap of the limiting hole 212 is smaller than the radial size of the unlocking rope 222, and the unlocking rope 222 can enter the limiting hole 212 through the gap of the limiting hole 212, wherein the gap of the limiting hole 212 is located on a side surface of the first part 214 away from the second part 215.

[0074] In this way, the unlocking pull rope 222 can be easily installed in the limiting hole 212, and the unlocking pull rope 222 can be prevented from withdrawing from the gap of the limiting hole 212, thereby improving the limiting effect.

[0075] It should be noted that the unlocking pull rope 222 can have a certain elasticity so that the unlocking pull rope 222 can be deformed when passing through the gap of the limiting hole 212 under the action of external force. After the unlocking pull rope 222 passes through the gap and enters the limiting hole 212, it restores its original size, so that it can be stably clamped in the limiting hole 212.

[0076] In some embodiments of the present application, the locking assembly 22 may further include a harness tube 223 , which is engaged with the limiting hole 212 , and the unlocking pull rope 222 passes through the harness tube 223 .

[0077] It can be understood that, since the contact area between the unlocking pull rope 222 and the limiting part 211 is small, when the unlocking pull rope 222 moves back and forth in the limiting hole 212, it will be subjected to a large pressure, and it is easy to wear and break. After adding the harness drum 223, along the axial direction of the limiting hole 212, the length of the harness drum 223 can be made greater than the length of the limiting hole 212, so that the contact area between the unlocking pull rope 222 and the harness drum 223 can be larger, and the unlocking pull rope 222 is subjected to a small pressure when it moves back and forth in the harness drum 223, and it is not easy to wear and break. Therefore, the harness drum 223 can protect the unlocking pull rope 222 and prevent the unlocking pull rope 222 from breaking due to reciprocating friction with the limiting part 211 during the unlocking process.

[0078] In addition, since the wiring harness tube 223 is clamped in the limiting hole 212, the radial dimension of the wiring harness tube 223 is smaller than the radial dimension of the limiting hole 212, so that the wiring harness tube 223 can also reduce the radial movement space of the unlocking pull rope 222 in the limiting hole 212, reduce the radial shaking of the unlocking pull rope 222 during the movement, and thus improve the limiting effect of the unlocking pull rope 222.

[0079] In some embodiments, the axis of the harness tube 223 coincides with the axis of the limiting hole 212. When the unlocking pull rope 222 is pulled to unlock the guard plate 21, the moving direction of the unlocking pull rope 222 can be kept consistent with the force direction, thereby reducing the resistance of the unlocking pull rope 222 during movement, making it easier for the user to unlock.

[0080] Figure 5 The second structural diagram of the chair armrest provided by an embodiment of the present application is shown. Figure 6 Shows Figure 5 The enlarged structural diagram at A, combined with reference Figure 5 and Figure 6 In some embodiments of the present application, the seat armrest 2 may further include a first connecting shaft 23, and the first connecting shaft 23 is fixedly connected to the seat.

[0081] The guard plate 21 is rotatably connected to the first connecting shaft 23 , wherein the rotation axis of the guard plate 21 coincides with the axis of the first connecting shaft 23 .

[0082] The locking member 221 may include an active locking member 2211, a driven locking member 2212 and a locking control member 2213, wherein the active locking member 2211 is connected to the first connecting shaft 23, the driven locking member 2212 is located at one side of the active locking member 2211, the driven locking member 2212 is rotatably connected to the guard plate 21, and can be pressed against the active locking member 2211, the locking control member 2213 is provided on the guard plate 21 and connected to the unlocking pull rope 222, and can move between a first position and a second position, and the locking control member 2213 moves from the second position to the first position. During the process of changing the position, it is able to contact the driven locking member 2212 and push the driven locking member 2212 to press on the active locking member 2211; when the locking control member 2213 moves to the first position, the locking control member 2213 presses on the driven locking member 2212, and the driven locking member 2212 presses on the active locking member 2211, and when the locking control member 2213 is in the second position, the locking control member 2213 is separated from the driven locking member 2212, so that the active locking member 2211 releases the pressure on the driven locking member 2212. In this way, when there is no need to adjust the seat armrest 2, the locking control member 2213 can be moved from the second position to the first position to push the driven locking member 2212 to press against the active locking member 2211, so that the active locking member 2211 generates resistance to the driven locking member 2212 to prevent the driven locking member 2212 from rotating relative to the active locking member 2211, thereby preventing the guard plate 21 assembly from rotating relative to the first connecting shaft 23, that is, locking the guard plate 21 assembly to improve the stability of the seat armrest 2.

[0083] When the seat armrest 2 needs to be unlocked, the locking control member 2213 can be separated from the driven locking member 2212 first to reserve rotation space for the driven locking member 2212. The active locking member 2211 can rotate relative to the driven locking member 2212, so that the guard plate 21 rotatably connected to the driven locking member 2212 can rotate around the first connecting shaft 23, thereby completing the unlocking process of the seat armrest 2.

[0084] like Figure 6 As shown, the active locking member 2211 can be an annular structure, the inner ring surface of the active locking member 2211 is welded to the first connecting shaft 23, and a groove is set on the outer ring surface of the active locking member 2211. The structure of the groove can be set as a V-shaped groove.

[0085] The driven locking member 2212 may include a protrusion 2212a and an abutment 2212b, wherein the protrusion 2212a may be configured as a V-shaped structure adapted to the V-shaped groove so that the protrusion 2212a may slide out of the groove under the action of an external force. The abutment 2212b may be configured as a planar structure, wherein the protrusion 2212b is disposed toward the active locking member 2211, and the abutment 2212b is disposed toward the locking control member 2213.

[0086] In this way, when the locking control member 2213 is in the first position, the locking control member 2213 can smoothly abut against the surface of the abutment portion 2212b, so that the protrusion 2212a is tightly engaged with the slot; when the locking control member 2213 is in the second position, the locking control member 2213 is separated from the abutment portion 2212b. At this time, the user can drive the guard plate 21 to rotate around the first connecting shaft 23 within a smaller angle range first, driving the driven locking member 2212 to revolve around the active locking member 2211. The driven locking member 2212 also rotates while revolving, so that the protrusion 2212b gradually slides out of the slot, and the driven locking member 2212 and the active locking member 2211 can be completely released from the engaged state, so that the guard plate 21 can continue to rotate around the first connecting shaft 23, completing the unlocking process of the seat armrest 1.

[0087] Continue reading Figure 6 The locking control component 2213 may include a rotating base plate 2213a, a connecting portion 2213b and a pressing portion 2213c. The rotating base plate 2213a is rotatably connected to the guard plate 21, one end of the connecting portion 2213b is connected to the rotating base plate 2213a, the other end of the connecting portion 2213b is connected to the unlocking pull rope 222, one end of the pressing portion 2213c is connected to the rotating base plate 2213a, and the other end of the pressing portion 2213c can be pressed against the abutting portion 2212b.

[0088] In this way, when the unlocking pull rope 222 transmits the driving force to the connecting part 2213b of the locking control component 2213, the rotating base plate 2213a can rotate under the action of the driving force, thereby driving the pressing part 2213c to rotate, so that the pressing part 2213c of the locking control component 2213 and the contact part 2212b of the driven locking component 2212 switch between the pressing and separation states, thereby realizing the control of the driven locking component 2212 by the locking control component 2213.

[0089] Figure 7 Shows Figure 5 For the enlarged schematic diagram at B, see Figure 7 In some embodiments of the present application, the seat armrest 2 may further include a driving member 24 and a connecting plate 25, the driving member 24 is rotatably connected to the connecting plate 25, and is used to drive the locking control member 2213 to move from the second position to the first position, and the driving member 24 is provided with a driving end 241 and a driven end 242 arranged at intervals around the rotation axis of the driving member 24, the driving end 241 is connected to the operating rod 243, and the driven end 242 is connected to the other end of the unlocking pull rope 222, and the opposite ends of the connecting plate 25 are respectively connected to the two guard plates 21.

[0090] In this way, the user pulls the operating rod 243 to cause the driving end 241 of the driving member 24 to rotate relative to the guard plate 21, and at the same time, the driven end 242 of the driving member 24 also rotates accordingly, and drives the connecting member connected to the driven end 242 to move. The movement of the connecting member can pull the locking control member 2213, so that the locking control member 2213 can move from the second position to the first position. A lever is formed between the operating rod 243 and the driving member 24, so that the user can save more effort during the switching process.

[0091] It is understandable that during the rotation of the driving member 24, the unlocking rope 222 on one side may be tightened while the unlocking rope 222 on the other side may be loosened, causing the locking control member 2213 on one side to switch positions while the locking control member 2213 on the other side remains in the same position, thereby causing the locking assemblies 22 on both sides to move asynchronously, thereby causing motion interference during the unlocking process.

[0092] In order to solve the above problems, in some embodiments of the present application, the driven end 242 may include a first driven end 2421 and a second driven end 2422, the first driven end 2421 and the second driven end 2422 are circumferentially spaced around the rotation axis of the driving member 24, and the first driven end 2421 is located on the right side of the connecting plate, and the second driven end 2422 is located on the left side of the connecting plate. For the sake of convenience, the unlocking pull rope 222 located on the right side of the seat armrest 2 is the first unlocking pull rope 2221, and the unlocking pull rope 222 located on the left side of the seat armrest 2 is the second unlocking pull rope 2222, one end of the first unlocking pull rope 2221 is connected to the first driven end 2421, one end of the second unlocking pull rope 2222 is connected to the second driven end 2422, and the other ends of the first unlocking pull rope 2221 and the second unlocking pull rope 2222 are both connected to the locking control member 2213.

[0093] In this way, when the driving member 24 rotates, the first unlocking rope 2221 and the second unlocking rope 2222 can both be in a tensioned state, thereby ensuring that the driving force can be simultaneously transmitted to the two locking control members 2213 on both sides of the first connecting shaft 23, so that the position switching state of the locking control member 2213 remains consistent.

[0094] It should be noted that the structure of the driving member 24 here can be as follows Figure 7 As shown, three rod-like structures are arranged circumferentially at intervals around the rotation axis, and a connecting hole is opened at the end of each rod. It can also be a form in which three connecting holes are arranged circumferentially at intervals around the rotation axis on a flat plate.
