[0037] In the description of the present invention, "first feature" or "second feature" may include one or more of the features.

[0038] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0039] A wire adjustment device 1 according to an embodiment of the present utility model is described below with reference to the accompanying drawings.

[0040] like Figure 1-Figure 6 As shown, the wire adjustment device 1 according to the embodiment of the utility model includes a housing 100 , a fixing seat 200 , a locking mechanism 300 , a driven wire assembly 400 and an active wire assembly 500 .

[0041] The shell 100 is constructed with an installation cavity 130, the fixed seat 200 is movably disposed in the installation cavity 130, the locking mechanism 300 is disposed in the installation cavity 130, and the locking mechanism 300 is used to lock or unlock the fixed seat 200, one end of the driven wire assembly 400 is disposed in the installation cavity 130 and connected to the fixed seat 200, one end of the active wire assembly 500 is selectively transmission-connected to the fixed seat 200, and one end of the active wire assembly 500 is movably disposed in the fixed seat 200 to adjust the distance between one end of the active wire assembly 500 and one end of the driven wire assembly 400.

[0042] Among them, the driven wire assembly 400 can be connected to the first external adjustment mechanism component (for example, the first angle adjustment mechanism described below), and the active wire assembly 500 can be connected to the second external adjustment mechanism component (for example, the second angle adjustment mechanism described below). In this way, when the state of the second adjustment mechanism component is switched, the active wire assembly 500 can move accordingly, and the active wire assembly 500 can drive the driven wire assembly 400 to move through the fixed seat 200, and the driven wire assembly 400 then drives the first adjustment mechanism component to switch its state.

[0043] According to the wire pulling adjustment device 1 of the embodiment of the utility model, an installation cavity 130 is constructed inside the shell 100, the fixed seat 200 is movably arranged in the installation cavity 130, and the locking mechanism 300 is arranged in the installation cavity 130. In this way, the installation cavity 130 can fix the components of the wire pulling adjustment device 1, for example, the above-mentioned fixed seat 200 and the locking mechanism 300 can be fixed, and the shell 100 can also protect the fixed seat 200 and the locking mechanism 300 to avoid position interference between external components and the fixed seat 200 and the locking mechanism 300, and the structural setting is more reasonable.

[0044] In addition, the locking mechanism 300 is used to lock or unlock the fixed seat 200, and one end of the driven wire assembly 400 is disposed in the mounting cavity 130 and connected to the fixed seat 200. In this way, when the locking mechanism 300 unlocks the fixed seat 200, the fixed seat 200 can move relative to the housing 100, thereby enabling the driven wire assembly 400 to move relative to the housing 100 to extend and retract the driven wire assembly; and when the locking mechanism 300 locks the fixed seat 200, the fixed seat 200 is fixed relative to the housing 100, that is, the fixed seat 200 cannot move relative to the housing 100, and at this time, the driven wire assembly 400 cannot move relative to the housing 100, thereby indirectly locking the driven wire assembly 400.

[0045] In addition, one end of the active wire pulling assembly 500 is selectively transmission-connected to the fixed seat 200, so that when the active wire pulling assembly 500 moves, the active wire pulling assembly 500 can drive the fixed seat 20 to move together, and then the driven wire pulling assembly 500 can be driven to move through the fixed seat 200, so that the wire pulling adjustment device 1 can be used to adjust the states of the two external adjustment mechanism components to realize the linkage of the two adjustment mechanism components.

[0046] Furthermore, one end of the active wire assembly 500 is movably disposed in the fixed seat 200 to adjust the distance between one end of the active wire assembly 500 and one end of the driven wire assembly 400. In this way, when the locking mechanism 300 locks the fixed seat 200, the active wire assembly 500 can move in the fixed seat 200. At this time, there is no transmission relationship between the active wire assembly 500 and the fixed seat 200, and the fixed seat 200 does not move with the active wire assembly 500, that is, the driven wire assembly 400 does not move with the active wire assembly 500, so that the distance between the active wire assembly 500 and the driven wire assembly 400 can be adjusted to adjust the distance between the adjustment mechanism component connected to the active wire assembly 500 and the adjustment mechanism component connected to the driven wire assembly 400, and then the tolerance between the two adjustment mechanism components can be absorbed, so that the wire adjustment device 1 can match the stroke between the two adjustment mechanism components, and the operation control is more precise.

[0047] In this way, the wire adjustment device 1 according to the embodiment of the utility model can adjust the distance between the active wire assembly 500 and the driven wire assembly 400, and thus can absorb the tolerance of the adjustment mechanism components connected to the wire adjustment device 1, and the operation control accuracy is higher.

[0048] In some specific embodiments of the present invention, Figure 2 As shown, the active pull wire assembly 500 includes a transmission member 510 , a first pull wire 520 and an active member 530 .

[0049] A first accommodating cavity 210 is constructed in the fixed seat 200, and a first step 211 is constructed at one end of the first accommodating cavity 210 away from the driven pull wire assembly 400. The transmission member 510 is movably arranged in the first accommodating cavity 210 and can selectively abut against the first step 211. One end of the first pull wire 520 is connected to the transmission member 510, and the active member 530 is connected to the other end of the first pull wire 520, and the active member 530 is suitable for rotating around the first rotation axis to drive the first pull wire 520 to extend and retract relative to the shell 100.

[0050] By constructing a first step 211 at the end of the first accommodating chamber 210 away from the driven wire assembly 400, the first step 211 can stop the transmission member 510, thereby preventing the transmission member 510 from escaping from the first accommodating chamber 210 along the end of the first accommodating chamber 210 away from the driven wire assembly 400, and the structural setting is more reasonable.

[0051] Furthermore, by allowing the transmission member 510 to selectively abut against the first step 211, when the active wire assembly 500 moves in a direction away from the driven wire assembly 400, that is, when the active member 530 rotates around the first rotation axis and drives the first wire 520 to move in a direction away from the driven wire assembly 400, the transmission member 510 can abut against the first step 211, and the transmission member 510 can drive the fixed seat 200 to move together in a direction away from the driven wire assembly 400, and the fixed seat 200 drives the driven wire assembly 400 to move at the same time, thereby realizing the linkage between two adjustment mechanism components (such as the first angle adjustment mechanism and the second angle adjustment mechanism described below).

[0052] In addition, by extending and retracting the first pull wire 520 relative to the shell 100, the distance between the first pull wire 520 and the driven pull wire assembly 400 can be adjusted, thereby adjusting the distance between the two adjustment mechanism components. The pull wire adjustment device 1 can then be used to absorb the tolerance between the two adjustment mechanism components, so that the pull wire adjustment device 1 can match the stroke between the two adjustment mechanism components, and the operation control is more precise.

[0053] In some specific embodiments of the present invention, Figure 2 As shown, the wire adjustment device 1 further includes a first elastic member 240 .

[0054] A second accommodating chamber 220 is also constructed in the fixed seat 200. The second accommodating chamber 220 is arranged on the side of the first accommodating chamber 210 away from the driven pull wire assembly 400, and a second step 221 is constructed at the end of the second accommodating chamber 220 away from the first accommodating chamber 210. The first elastic member 240 is sleeved on the first pull wire 520 and is arranged in the second accommodating chamber 220. The two ends of the first elastic member 240 are respectively abutted against the transmission member 510 and the second step 221 to generate an elastic force that drives the transmission member 510 to move away from the second step 221.

[0055] The first elastic member 240 may be a spring.

[0056] That is to say, the second accommodating chamber 220 is arranged on the side of the first accommodating chamber 210 away from the driven wire assembly 400. By arranging the first elastic member 240 in the second accommodating chamber 220, the first elastic member 240 can generate an elastic force to drive the transmission member 510 to move away from the second step 221, that is, the first elastic member 240 can drive the transmission member 510 to move toward the direction close to the driven wire assembly 400 to reduce the distance between the active wire assembly 500 and the driven wire assembly 400, and then the distance between the active wire assembly 500 and the driven wire assembly 400 can be actively adjusted, so that the wire adjustment device 1 can be used to absorb the tolerance between the two adjustment mechanism components, and the control is more precise.

[0057] In addition, the inner diameter of the second accommodating chamber 220 can be smaller than the inner diameter of the first accommodating chamber 210, so that it is convenient to construct the first step 211 at the end of the first accommodating chamber 210 close to the second accommodating chamber 210. Moreover, by setting the inner diameter of the second accommodating chamber 220 to be smaller, the inner wall of the second accommodating chamber 220 can be used to radially limit the first elastic member 240 to avoid radial displacement of the first elastic member 240, so that the direction of the elastic force of the first elastic member 240 can be parallel to the axial direction of the fixing seat 200, thereby stably pushing the transmission member 510 to move along the axial direction of the fixing seat.

[0058] In some specific embodiments of the present invention, Figure 2 and Figure 4 As shown, the wire adjustment device 1 further includes a second elastic member 140 .

[0059] A third step 132 is provided at one end of the installation cavity 130 away from the driven pull wire assembly 400, and the second elastic member 140 is sleeved on the first pull wire 520 and is provided in the installation cavity 130, and the two ends of the second elastic member 140 are respectively abutted against the third step 132 and the fixed seat 200 to generate an elastic force that drives the fixed seat 200 to move away from the third step 132.

[0060] The second elastic member 140 may also be a spring.

[0061] By setting a third step 132 at the end of the installation cavity 130 away from the driven wire assembly 400, the third step 132 can stop the second elastic member 140, thereby preventing the second elastic member 140 from detaching from the installation cavity 130 along the end of the installation cavity 130 away from the driven wire assembly 400, and the structural setting is more reasonable.

[0062] Furthermore, by bringing the second elastic member 140 into contact with the third step 132, the second elastic member 140 can generate an elastic force that drives the fixed seat 200 to move away from the third step 132, that is, the second elastic member 140 can drive the fixed seat 200 to move toward the direction approaching the driven wire assembly 400, and the driven wire assembly 400 can move toward the direction away from the active wire assembly 500, thereby adjusting the states of the two adjustment mechanism components.

[0063] In some embodiments of the present invention, a fifth step 133 may be provided at one end of the installation cavity 130 away from the active pull wire assembly 500, and the fifth step 133 may stop the fixing seat 200 to prevent the fixing seat 200 from detaching from the end of the installation cavity 130 close to the driven pull wire assembly 400.

[0064] In some specific embodiments of the present invention, Figure 2 and Figure 3As shown, the locking mechanism 300 includes a limit block 310 and a ball 320 .

[0065] A fourth step 212 is constructed at the end of the first accommodating chamber 210 away from the active pull wire assembly 500, and the limit block 310 is movably arranged in the first accommodating chamber 210 and is located between the fourth step 212 and the transmission member 510. In this way, the fourth step 212 can stop the limit block 310 to prevent the limit block 310 from detaching from the end of the first accommodating chamber 210 away from the active pull wire assembly 500, and the structural setting is more reasonable.

[0066] In addition, a positioning groove 311 is provided on the circumference of the limit block 310, and a positioning hole 201 is constructed on the circumference of the fixed seat 200. The ball 320 is rotatably arranged in the positioning groove 311 and the positioning hole 201, wherein the side wall of the mounting cavity 130 is recessed to form a locking groove 131. When the fixed seat 200 and the locking mechanism 300 move along the axial direction of the mounting cavity 130 to be opposite to the locking groove 131, the ball 320 rolls into the locking groove 131 and the positioning hole 201 to lock the relative position of the fixed seat 200 and the shell 100.

[0067] In this way, when the locking mechanism 300 is in the unlocked state, the ball 320 can be arranged in the positioning groove 311 and the positioning hole 201. At this time, the ball 320 will not limit the movement of the fixed seat 200, and the fixed seat 200 can move normally along the axial direction of the installation cavity 130, so that the active pull wire assembly 500 and the driven pull wire assembly 400 can be linked, so that the two adjustment mechanism components connected to the active pull wire assembly 500 and the driven pull wire assembly 400 can be linked.

[0068] When the ball 320 rolls into the locking groove 131 and the positioning hole 201, the limit block 310 and the side wall of the locking groove 131 can limit and lock the ball 320 in the radial direction of the fixed seat 200, and the ball 320 can only move in the locking groove 131 along the axial direction of the fixed seat 200 shell 100, thereby limiting the axial movement of the fixed seat 200 in the shell 100, that is, the fixed seat 200 cannot move freely in the axial direction of the shell 100, and then the fixed seat 200 can be locked, and the driven pull wire assembly 400 is locked.

[0069] Among them, when the fixed seat 200 is locked, the transmission member 510 can move in the fixed seat 200, that is, the transmission member 510 can move between the first step 211 and the limit block 310, and then the distance between the transmission block 510 and the driven wire assembly 400 can be adjusted, so as to adjust the distance between the active wire assembly 500 and the driven wire assembly 400, so that the wire adjustment device 1 can be used to absorb the tolerance between the two adjustment mechanism components, and the control is more precise.

[0070] Furthermore, in some embodiments, Figure 4-Figure 6 As shown, the limit block 310 may be provided with a sliding protrusion 313, and the fixed seat 200 may be provided with a sliding groove 260, and the sliding groove 260 may extend along the axial direction of the fixed seat 200, and the sliding protrusion 313 may be slidably matched in the sliding groove 260, thereby limiting the limit block 310 to slide only along the axial direction of the first accommodating cavity 210, preventing the limit block 310 from rotating in the first accommodating cavity 210, and making the matching more stable. In addition, there may be multiple sliding protrusions 313, for example, multiple sliding protrusions 313 may be provided on two radially opposite sides of the limit block 310, and the sliding grooves 260 may also be multiple and provided on two radially opposite sides of the fixed seat 200, and through the one-to-one matching of multiple sliding protrusions 313 and multiple sliding grooves 260, the matching stability of the limit block 310 and the fixed seat 200 can be further improved, so that the sliding of the limit block 310 in the fixed seat 200 is more stable.

[0071] In some specific embodiments of the present invention, Figure 2 As shown, the locking mechanism 300 further includes a third elastic member 330 .

[0072] A limiting hole 312 is constructed on one side of the limiting block 310 facing the fourth step 212, and the third elastic member 330 is arranged in the limiting hole 312, and the two ends of the third elastic member 330 are respectively abutted against the bottom wall of the limiting hole 312 and the fourth step 212 to generate an elastic force that pushes the limiting block 310 to move away from the fourth step 212.

[0073] By setting the third elastic member 330 between the fourth step 212 and the limit block 310, the third elastic member 330 can generate an elastic force to push the limit block 310 to move in the direction away from the fourth step 212. When the ball 320 rolls into the locking groove 131 and the positioning hole 201, the ball 320 rolls out of the positioning groove 311. At this time, the third elastic member 330 can push the limit block 310 to move in the direction away from the fourth step 212, so that the locking mechanism 300 can be switched from the unlocked state to the locked state to lock the fixed seat 200.

[0074] In addition, by setting the limiting hole 312, one end of the third elastic member 330 facing the limiting block 310 can be fixed in the limiting hole 312, and the limiting hole 312 can radially limit the third elastic member 330, which is beneficial to improve the reliability of the position fixation of the third elastic member 330 and avoid the position displacement of the third elastic member 330, so that the third elastic member 330 can stably provide elastic force to push the limiting block 310 to move.

[0075] In some specific embodiments of the present invention, Figure 2 As shown, the driven wire assembly 400 includes a stopper 410 , a second wire 420 and a driven member 430 .

[0076] The fixing seat 200 is also constructed with a limiting groove 250, the limiting member 410 is installed in the limiting groove 250, one end of the second pull wire 420 is connected to the limiting member 410, the follower 430 is connected to the other end of the second pull wire 420, and the follower 430 is suitable for rotating around the second rotation axis to drive the second pull wire 420 to extend and retract relative to the shell 100.

[0077] With such an arrangement, the driven wire assembly 400 can be fixed in the limiting groove 250 by means of the limiting member 410, and then the driven wire assembly 400 and the fixed seat 200 can be connected together. When the first adjusting mechanism component drives the fixed seat 200 to move through the active wire assembly 500, the fixed seat 200 can drive the limiting member 410 to move together. The limiting member 410 then drives the driven member 430 to rotate around the second rotation axis through the second wire 420. The driven member 430 cooperates with another adjusting mechanism component, thereby realizing the linkage of the two adjusting mechanism components.

[0078] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the housing 100 includes a first housing 110 and a second housing 120 .

[0079] The first shell 110 and the second shell 120 are detachably connected, and the first shell 110 and the second shell 120 are arranged along the axial direction of the shell 100 and jointly define the installation cavity 130. By dividing the shell 100 into the first shell 110 and the second shell 120, not only the structure of the shell 100 can be simplified and the processing can be facilitated, but also the assembly of the wire adjustment device 1 can be simplified. After the parts are installed in the first shell 110 and the second shell 120, the first shell 110 and the second shell 120 can be fixed together, and the assembly is more convenient and quick.

[0080] In addition, a first sleeve 540 may be connected to the outside of the first shell 110, and the first pull wire 520 is passed through the first sleeve 540. The first sleeve 540 can guide and protect the first pull wire 520, so that the first pull wire 520 can be more easily extended and retracted relative to the shell 100; the second shell 120 is connected to the second sleeve 440, and the second pull wire 420 is passed through the second sleeve 440. The second sleeve 440 can guide and protect the second pull wire 420, so that the second pull wire 420 can be more easily extended and retracted relative to the shell 100.

[0081] A seat assembly according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0082] The seat assembly includes a seat, a first angle adjustment mechanism, a second angle adjustment mechanism, and a wire adjustment device 1 according to the above embodiment of the utility model.

[0083] The seat includes a backrest and a seat cushion, a first angle adjustment mechanism is fixed to the backrest, a second angle adjustment mechanism is fixed to the seat cushion, a driven wire assembly 400 is connected to the first angle adjustment mechanism, and an active wire assembly 500 is connected to the second angle adjustment mechanism to adjust the angle of the backrest relative to the seat cushion. Therefore, when the angle of the backrest needs to be adjusted, the second angle adjustment mechanism can be controlled to move, and the second angle adjustment mechanism drives the second angle adjustment mechanism to move through the wire adjustment device 1, thereby adjusting the angle of the backrest.

[0084] According to the seat assembly of the embodiment of the utility model, by utilizing the wire adjustment device 1 according to the above embodiment of the utility model, the wire adjustment device 1 can adjust the distance between the active wire assembly 500 and the driven wire assembly 400, and then can absorb the tolerance of the adjustment mechanism components connected to the wire adjustment device 1, and the operation control accuracy is higher.

[0085] The following is an example to illustrate the movement process of the wire adjustment device 1 in the embodiment of the utility model.

[0086] The active member 530 may have a first initial position, a first locking position and a maximum stroke position, and the driven member may have a second initial position and a second locking position.

[0087] When the locking mechanism 300 does not lock the fixed seat 200, by controlling the second angle adjustment mechanism, the second angle adjustment mechanism can drive the active member 510 to move from the first initial position to the maximum stroke position, and then drive the active wire assembly 500 to move away from the driven wire assembly 400. At this time, the transmission member 510 can drive the fixed seat 200 to move together, so as to drive the driven wire assembly 400 to move together through the fixed seat 200, and the driven member 430 moves from the second initial position to the second locking position, and the driven member 430 can drive the first angle adjustment mechanism to move, so as to realize the linkage of the first angle adjustment mechanism and the second angle adjustment mechanism to adjust the angle of the backrest. After the adjustment is completed, the active member 530 can be locked in the first locking position by the second angle adjustment mechanism.

[0088] Furthermore, when the active wire pulling assembly 500 drives the fixed seat 200 to move, the ball 320 can roll into the locking groove 131, and the locking mechanism 300 locks the fixed seat 200. When the active member 530 is fixed in the first locking position, the transmission member 510 can move in the first accommodating cavity 210, that is, when the fixed seat 200 is locked, the distance between the active wire pulling assembly 500 and the driven wire pulling assembly 400 can be adjusted by moving the transmission member 510 in the first accommodating cavity 210, so that the wire pulling adjustment device 1 can be used to absorb the travel tolerance between the first angle adjustment mechanism and the second angle adjustment mechanism, and the control is more precise.

[0089] When the second angle adjustment mechanism is controlled to release the active member 510, the first elastic member 240 will push the transmission member 510 to move toward the direction close to the limit block 310, and push the limit block 310 to move toward the direction close to the fourth step 212 through the transmission member 510. The ball 320 returns to the positioning groove 311 and the positioning hole 201 again to unlock the fixed seat 200. Then the second elastic member 140 can push the fixed seat 200 to move toward the direction close to the driven pull wire assembly 400 to allow the driven pull wire assembly 400 to move away from the active pull wire assembly 500. At this time, the active member 530 can move from the first locking position to the first initial position, and the driven member 430 can move from the second locking position to the second initial position, so as to achieve reverse adjustment of the angle of the backrest.
