Description

Technical Field

[0001] This utility model relates to the field of automotive armrests, specifically to a single-cable unlocking armrest. Background Technology

[0002] Armrests are very common in cars, such as the armrests on the back of the rear seats. The armrests rotate on the rear seats and are normally located in the armrest groove on the back of the seat, so they do not affect people sitting in the seat. When the armrest is needed, it can be rotated out of the armrest groove.

[0003] In existing technology, the armrest has an internal frame with locking mechanisms on both sides. Two cables are attached to the frame, each connected to one of the locking mechanisms. Normally, the armrest is positioned within the armrest groove of the seat back, with the two locking mechanisms locked. The armrest does not automatically rotate out of the groove; it remains stably locked. When the armrest is needed, pulling the cables releases the locking mechanisms, allowing the armrest to rotate out of the groove for use.

[0004] However, currently the two cables are not operated synchronously, resulting in asynchronous unlocking of the locking mechanism. To unlock both locking mechanisms simultaneously, both cables need to be pulled with both hands at the same time, which is obviously cumbersome and does not improve operational convenience. If the cables are not pulled synchronously with both hands, the handrail will remain locked and cannot be rotated. Utility Model Content

[0005] The present invention aims to provide a single-cable unlocking handrail to solve the problem of asynchronous unlocking of the two locking mechanisms on the current handrail frame.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a single-cable unlocking handrail, comprising a handrail frame, with locking mechanisms installed on both sides of the handrail frame, a pull cable on the handrail frame, the pull cable being connected to one of the locking mechanisms, and a connecting rod connecting the two locking mechanisms.

[0007] The principle and advantages of this solution are as follows: By connecting the two locking mechanisms with a linkage, the two locking mechanisms are linked together. When unlocking is required, the cable is pulled, which unlocks one of the locking mechanisms. At the same time, this locking mechanism unlocks the other locking mechanism through the linkage, thus achieving synchronous unlocking of the two locking mechanisms. In this way, only one cable needs to be installed on the handrail, eliminating the need for two cables and separate operations on the two cables to unlock the handrail. The operation is simple and convenient.

[0008] This solution addresses the technical problem by simply adding a connecting rod between the two locking mechanisms and eliminating one cable. Compared to existing technologies, it requires minimal modification to the handrail, thus having little impact on handrail manufacturing. Therefore, this solution solves the technical problem at a lower cost.

[0009] Preferably, as an improvement, the handrail frame is provided with a fixing frame, and a lifting member is rotatably connected to the fixing frame. The end of the pull cable away from the locking mechanism is connected to the lifting member, and the handrail frame is provided with a first elastic member for resetting the lifting member after it is pulled.

[0010] Thus, the lifting component is rotatably mounted on the fixed frame. When unlocking is required, pulling the lifting component causes it to rotate, which in turn moves the cable, pulling the locking mechanism and thus unlocking the device. Simultaneously, the rotation of the lifting component causes the first elastic element to store force. When the lifting component is no longer pulled, it rotates in the opposite direction under the elastic force of the first elastic element and resets.

[0011] Preferably, as an improvement, a fixed shaft is provided on the handrail frame, and the handrail frame is rotatably connected to the fixed shaft;

[0012] The locking mechanism includes a movable part and a fixed part. The fixed part is fixedly connected to the fixed shaft, and the movable part is movably connected to the handrail frame. When the movable part acts on the fixed part, the locking mechanism is in the locked state, and when the movable part and the fixed part are separated, the locking mechanism is in the unlocked state.

[0013] The connecting rod is fixedly connected between two moving parts.

[0014] Therefore, when the movable part acts on the fixed part, the locking mechanism is in the locked state. At this time, since the fixed part is fixed on the fixed shaft, the handrail frame cannot rotate. When unlocking is required, by pulling the cable, one of the movable parts is separated from the fixed part. This movable part moves and no longer acts on the fixed part. At the same time, this movable part drives the other movable part to move through the connecting rod. The other movable part also no longer acts on the fixed part, thus realizing the synchronous unlocking of the two locking mechanisms. At this time, the handrail frame can be rotated, and the fixed part no longer restricts the handrail frame, allowing the handrail frame to rotate on the fixed shaft.

[0015] Preferably, as an improvement, a fixed shaft is provided on the handrail frame, and the handrail frame is rotatably connected to the fixed shaft;

[0016] The locking mechanism includes a control component, a movable component, and a fixed component. The fixed component is fixedly connected to a fixed shaft, and the movable component and the control component are rotatably connected to the handrail frame. The movable component is located between the fixed component and the control component. When the movable component acts on the fixed component, the locking mechanism is in the locked state, and when the movable component and the fixed component are separated, the locking mechanism is in the unlocked state.

[0017] The linkage is fixedly connected between the two control components;

[0018] The movable part is provided with a pressing part and a turning end, and the control part is provided with a swinging end; when the swinging end abuts against the pressing part, the movable part acts on the fixed part; the swinging end pushes the turning end to separate the movable part and the fixed part.

[0019] Therefore, when the swing end abuts against the pressing part, the movable part acts on the fixed part, and the locking mechanism is in the locked state. At this time, since the fixed part is fixed on the fixed shaft, the handrail frame cannot rotate. When unlocking is required, the cable is pulled, which drives one of the control parts to rotate. The swing end on the control part swings, and the swing end no longer abuts against the pressing part. The swing end pushes the actuating end, thereby causing the movable part to rotate. The movable part separates from the fixed part, and the movable part no longer acts on the fixed part, thus unlocking the corresponding locking mechanism. At the same time, the control part drives another control part to rotate through the connecting rod. According to the same unlocking principle, the other locking mechanism also unlocks synchronously.

[0020] Preferably, as an improvement, the fixed part is provided with a slot, and the movable part is provided with an insertion end, and when the movable part acts on the fixed part, the insertion end is inserted into the slot.

[0021] Thus, by inserting the insertion end into the slot, the locking mechanism is locked; when the insertion end is pulled out of the slot, the moving part no longer acts on the fixed part, and the locking mechanism is in the unlocked state.

[0022] Preferably, as an improvement, the movable component is rotatably connected to the armrest frame.

[0023] Preferably, as an improvement, the handrail frame is provided with a second elastic element for ensuring that the movable part acts tightly against the fixed part; the cable is connected to the movable part. Thus, by providing the second elastic element, the movable part can act tightly against the fixed part, and the movable part will not easily detach from the fixed part when the cable is not pulled.

[0024] Preferably, as an improvement, the handrail frame is provided with a second elastic element for tightly abutting the swing end and the pressing part, and the cable is connected to the control element. Thus, by providing the second elastic element, the swing end and the pressing part can be tightly abutted, thereby making the moving part act tightly on the fixed part, and the moving part will not easily detach from the fixed part when the cable is not pulled.

[0025] Preferably, as an improvement, the control component is further provided with a first connecting end and a second connecting end, the first connecting end being connected to the cable and the second connecting end being connected to the second elastic element.

[0026] Preferably, as an improvement, the movable part is provided with a receiving groove, the swing end is located in the receiving groove, and the pressing part and the actuating end are respectively located on both sides of the receiving groove. The receiving groove realizes the accommodation of the swing end. When the swing end moves towards the pressing part, the swing end presses against the pressing part, and the movable part acts on the fixed part; when the swing end moves towards the actuating end, the swing end pushes the actuating end, the movable part rotates, and the movable part no longer acts on the fixed part.

[0035] Example 1

[0036] The basics are as follows: Figures 1-6 As shown: A single-cable unlocking handrail includes a handrail frame 1 and a filling material such as foam located on the outside of the handrail frame (the improvement in this embodiment is unrelated to the filling material such as foam, so the filling material such as foam is not shown). There are two handrail frames 1, which are arranged opposite to each other and connected by a connecting plate. Locking mechanisms are installed on both inner sides of the handrail frame 1. A pull cable 4 is provided on the handrail frame 1, and the pull cable 4 is connected to one of the locking mechanisms. A connecting rod 11 is connected between the two locking mechanisms.

[0037] In this embodiment, a fixing frame 2 is connected to the handrail frame 1. A lifting member 3 is rotatably connected to the fixing frame 2 via a pin. In this embodiment, the lifting member 3 is plate-shaped. The end of the pull cable 4 away from the locking mechanism is connected to the lifting member 3 by a hook. The handrail frame 1 is provided with a first elastic member 5 for resetting the lifting member 3 after it is pulled. In this embodiment, the first elastic member 5 is a tension spring. One end of the tension spring is hooked to the handrail frame 1, and the other end of the tension spring is hooked to the end of the lifting member 3. The end of the lifting member 3 away from the first elastic member 5 can be connected to a pull rope (or pull strap). In this way, the handrail frame 1 is located in the handrail, and the pull rope passes out from the handrail. By pulling the pull rope on the outside of the handrail, the pull rope drives the lifting member 3 inside the handrail to rotate. Figure 2 (When the lifting component 3 rotates counterclockwise, the lifting component 3 pulls the cable 4 upward.)

[0038] A fixed shaft 8 is threaded through the armrest frame 1, and the fixed shaft 8 is fixed to the car seat back and will not rotate. The armrest frame 1 is rotatably connected to the fixed shaft 8, specifically in the form of a combination of... Figure 4 As shown, a rotating sleeve 12 is welded and fixed on the fixed shaft 8. The inner wall of the shaft hole of the handrail frame 1 is located in the rotating groove of the rotating sleeve 12. The handrail frame 1 rotates in the rotating groove of the rotating sleeve 12, thereby realizing the rotation of the handrail frame 1 on the fixed shaft 8.

[0039] The two locking mechanisms in this embodiment are identical. Both locking mechanisms include a control element 9, a movable element 6, and a fixing element 7. The control element 9, movable element 6, and fixing element 7 are all located inside the handrail frame 1. In this embodiment, the fixing element 7 is fixedly connected (e.g., by welding or by a key) to the fixed shaft 8, so that the fixing element 7 will not rotate relative to the fixed shaft 8. Figure 4 As shown, the fixing member 7 in this embodiment is similar to a circle, and a slot 71 is provided on the circumferential side of the fixing member 7.

[0040] In this embodiment, both the movable component 6 and the control component 9 are rotatably connected to the handrail frame 1. The movable component 6 and the control component 9 are located on the side of the fixed component 7 near the cable 4, with the movable component 6 positioned between the fixed component 7 and the control component 9. When the movable component 6 acts on the fixed component 7, the locking mechanism is in a locked state; when the movable component 6 and the fixed component 7 are separated, the locking mechanism is in an unlocked state. Figure 6As shown, in this embodiment, the movable member 6 is provided with an insertion end 61, and the top of the movable member 6 is provided with a receiving groove 62. One side of the receiving groove 62 is a pressing part 63 located above the insertion end 61, and the other side of the receiving groove 62 is a toggle end 64 integrally located on the movable member 6. The pressing part 63 is higher than the bottom of the receiving groove 62. The movable member 6 is provided with a first rotating hole 65, and a pin is fixed on the armrest frame 1 and inserted into the first rotating hole 65. By rotating on the pin through the first rotating hole 65, the movable member 6 is rotatably connected to the armrest frame 1.

[0041] Combination Figure 5 As shown, in this embodiment, the control component 9 is provided with a swing end 94, a first connecting end 95, and a second connecting end 93. The control component 9 is provided with a second rotating hole 92, and a pin is fixed on the handrail frame 1 and inserted into the second rotating hole 92. The control component 9 rotates on the pin through the second rotating hole 92, thereby realizing the rotatable connection of the control component 9 on the handrail frame 1. In this embodiment, a second elastic element 10 is connected between the second connecting end 93 and the handrail frame 1. In this embodiment, the second elastic element 10 is a tension spring, located on the side of the control component 9 away from the movable part 6. One end of the tension spring is hooked on the handrail frame 1, and the other end of the tension spring is hooked on the second connecting end 93. The first connecting end 95 of one of the two locking mechanisms, the control component 9, is connected to the end of the cable 4 (e.g., by snap-fit, welding, bolting, etc.). In this embodiment, the control component 9 is installed on the handrail frame 1, and the swing end 94 is located in the receiving groove 62 of the movable part 6. Under the action of the second elastic member 10, the control member 9 causes the pressing surface 91 of the swing end 94 to abut against the pressing part 63, and the insertion end 61 of the movable member 6 is inserted into the slot 71. At this time, the locking mechanism is in the locked state.

[0042] In this embodiment, the connecting rod 11 is fixedly connected (e.g., welded) between the two control components 9, and the rotation centers of the connecting rod 11 and the control components 9 are coaxially arranged.

[0043] The specific implementation process is as follows: (Combined with...) Figures 1-3 As shown, when the armrest is located in the armrest groove in the seat back, the control member 9, under the pulling action of the second elastic member 10, causes the abutting surface 91 of the swing end 94 to press against the abutting part 63 on the movable member 6. The insertion end 61 of the movable member 6 is inserted into the slot 71. Under the abutting action of the swing end 94, the insertion end 61 of the movable member 6 will not disengage from the slot 71. At this time, the locking mechanism is in the locked state, the armrest frame 1 will not rotate on the fixed shaft 8, and the armrest is stably located in the armrest groove of the seat back.

[0044] When you need to unlock and use the handrail, pull the cord; the cord will then move... Figure 2 The lifting component 3 rotates counterclockwise, pulling the cable 4 upwards. The cable 4 pulls one of the control components 9, causing the control component 9 to rotate. Figure 5 When the control element 9 rotates clockwise, the swing end 94 of the control element 9 no longer presses against the pressing part 63, and the swing end 94 moves towards the actuating end 64 of the movable element 6. The swing end 94 pushes the actuating end 64, thereby causing the movable element 6 to rotate. Figure 6 (When the movable part 6 rotates counterclockwise), the insertion end 61 of the movable part 6 is pulled out from the slot 71, and the insertion end 61 is no longer inserted into the slot 71, thereby unlocking the corresponding locking mechanism.

[0045] At the same time, when the cable 4 pulls one of the control components 9 to rotate, the control component 9 drives the control component 9 on the other locking mechanism to rotate through the connecting rod 11, and the other locking mechanism is unlocked in the same way.

[0046] Therefore, in this embodiment, when the cable 4 is pulled, the cable 4 drives one of the control components 9 to rotate. This control component 9, through the connecting rod 11, drives the other control component 9 to rotate, thus enabling the synchronous unlocking of the two locking mechanisms. The operation is simple and convenient. After the armrest is unlocked, it can be rotated out from the armrest groove of the seat back for use.

[0047] Example 2

[0048] This embodiment provides a locking mechanism different from that of Embodiment 1. The locking mechanism in Embodiment 1 includes a control member 9, a movable member 6, and a fixing member 7. In this embodiment, the control member 9 is omitted, leaving only the movable member 6 and the fixing member 7. Simultaneously, a second elastic member 10 is connected to the actuating end 64, and a cable 4 is connected to the pressing portion 63 of one of the movable members 6. A connecting rod 11 connects the two movable members 6, and the rotation centers of the connecting rod 11 and the movable members 6 are coaxially arranged.

[0049] Therefore, when the armrest is located in the armrest groove of the seat back, the movable member 6, under the action of the second elastic member 10, causes the insertion end 61 to insert into the slot 71 of the fixed member 7, and the locking mechanism is in the locked state. When unlocking is required, the pull cable 4 is pulled, the pull cable 4 pulls the movable member 6, the movable member 6 rotates, and the insertion end 61 of the movable member 6 is pulled out from the slot 71, thereby realizing unlocking. At the same time, the movable member 6 connected to the pull cable 4 drives the movable member 6 of another locking mechanism to rotate through the connecting rod 11. According to the same principle, the other locking mechanism is also unlocked synchronously.

[0050] Example 3

[0051] The difference between this embodiment and embodiment 2 is that the movable component 6 can also be in other ways. For example, the movable component can be a pin, which slides along the length of the handrail frame 1 on its inner wall. The second elastic component is a compression spring, which presses against the movable component. Under the action of the compression spring, the movable component inserts its insertion end into the slot 71, thereby locking the locking mechanism. When unlocking is required, the pull cable 4 is pulled, which causes the movable component to slide away from the fixed component 7. The movable component is then pulled out of the slot 71, unlocking the locking mechanism. At the same time, the movable component drives the movable component of another locking mechanism to slide through the connecting rod 11, and the other locking mechanism is also unlocked simultaneously.

[0052] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
