[0058] Transmission damping structure:

[0059] The transmission damping structure in the embodiment of the present application is as follows: Figure 1-Figure 4 As shown, the transmission damping structure includes an actuating assembly arranged on an action component and a damping assembly arranged on a fixed component. The action component includes a sliding member and a rotating member rotatably mounted on the sliding member through a rotating shaft. The sliding member is slidably mounted on the fixed component.

[0060] Figure 1 , 2The fixed component and the moving component shown are the armrest 10 and the table top assembly 20, respectively, wherein the table top assembly 20 includes a sliding plate 201 and a table top body 202 rotatably mounted on the sliding plate 201, and the sliding plate 201 is slidably mounted on the armrest 10. The sliding plate 201 is a sliding part, and the table top body 202 is a rotating part. During actuation, the sliding plate 201 first drives the table top body 202 to slide on the armrest 10. When the sliding plate 201 slides to the uppermost end, the table top body 202 completely extends above the armrest 10. At the same time, the actuating assembly cooperates with the damping assembly, and then the sliding plate 201 continues to slide upward, and the transmission between the actuating assembly and the damping assembly drives the table top body 202 to rotate relative to the sliding plate 201, so that the table top body 202 rotates to a horizontal position. For the actuation process of the table top assembly 20, please refer to Figure 9-11 , which will be introduced in detail later.

[0061] like Figure 2-Figure 4 As shown, the actuating assembly includes a trigger member 01 for mounting on a sliding member and a transmission gear set 02 for mounting on a rotating shaft;

[0062] The damping assembly includes a base 03 provided with a slide groove 31, a starter 04 arranged in the base 03, a gear condition 05 and a blocking member 06 slidably mounted on the slide groove 31, and a damping member 07 connecting the base 03, the gear condition 05 and the blocking member 06, the gear condition 05 is locked in the base 03, a first elastic member 08 is arranged between the gear condition 05 and the base 03, a second elastic member 09 is arranged between the gear condition 05 and the blocking member 06, and the gear condition 05 is used to mesh with the transmission gear set 02;

[0063] When the sliding member slides upward until the trigger member 01 triggers the starting member 04 for the first time, the gear condition 05 is unlocked and the first elastic member 08 is triggered to push the gear condition 05 to slide upward to drive the transmission gear set 02 to rotate forward. When the sliding member slides downward until the trigger member 01 triggers the starting member 04 again, the damping member 07 is unlocked and the second elastic member 09 is triggered to push the gear condition 05 to slide downward to drive the transmission gear set 02 to rotate reversely.

[0064] Specifically, the base 03 is fixedly set on the fixed component, and the base 03 remains stationary during the actuation process. A slide groove 31 is set on the base 03, and the gear condition 05 and the blocking member 06 can be slidably installed in the slide groove 31, wherein the blocking member 06 is located above the gear condition 05. The base 03 is also provided with a mounting seat 32 below the slide groove 31 for installing the starting member 04. When the gear condition 05 and the damping member 07 are locked, they partially extend into the mounting seat 32 and are locked by the starting member 04.

[0065] Among them, the gear condition 05 is used to mesh with the transmission gear set 02 to achieve transmission. When the transmission gear set 02 slides with the sliding member to mesh with the gear condition 05, the transmission gear set 02 includes a driving gear 21, a transmission gear 22 and a shaft gear 23 that are meshed and connected in sequence, wherein the driving gear 21 is used to mesh with the gear condition 05, and the transmission gear 22 is used to achieve transmission between the driving gear 21 and the shaft gear 23. The shaft gear 23 is fixed on the shaft so that the shaft gear 23 rotates synchronously with the shaft. According to the requirements of the rotation angle between the sliding member and the rotating member, the transmission ratio between the three gears can be adjusted to achieve reasonable transmission.

[0066] like Figure 4 , 5 As shown, in the initial state, the first elastic member 08 is connected between the gear condition 05 and the mounting seat 32, the first elastic member 08 is compressed when the gear condition 05 is locked, the second elastic member 09 is connected between the gear condition 05 and the blocking member 06, and the damping member 07 connects the blocking member 06, the gear condition 05 and the mounting seat 32 to limit the sliding of the gear condition 05 and the blocking member 06.

[0067] like Figure 6 As shown, when the sliding member slides upward and drives the trigger member 01 to trigger the starting member 04 for the first time, the starting member 04 is actuated to unlock the gear condition 05, and the gear condition 05 slides upward along the slide groove 31 under the elastic force of the first elastic member 08, and at the same time pushes the second elastic member 09 and the blocking member 06 to slide upward. Since the gear condition 05 is meshed with the transmission gear set 02, the sliding of the gear condition 05 drives the transmission gear set 02 to rotate, thereby driving the rotating shaft between the rotating member and the sliding member to rotate, thereby realizing the positive rotation of the rotating member relative to the sliding member.

[0068] like Figure 7 As shown, when the sliding member slides downward and drives the trigger member 01 to trigger the starting member 04 again, the starting member 04 unlocks the damping member 07, triggering the second elastic member 09 to push the gear condition 05 to slide downward, thereby driving the transmission gear set 02 to rotate in the opposite direction, realizing the anti-phase rotation of the rotating member relative to the sliding member.

[0069] The transmission damping structure in the embodiment of the present application, as the sliding part slides upward, the trigger part 01 triggers the starting part 04 for the first time, and the unlocking gear condition 05 slides upward, thereby driving the transmission gear set 02 meshing therewith to rotate forward, thereby driving the rotating part to rotate forward relative to the sliding part, and then as the sliding part slides downward, the trigger part 01 triggers the starting part 04 again, and the unlocking gear condition 05 slides downward, thereby driving the transmission gear set 02 to rotate in the opposite direction, thereby driving the rotating part to rotate in the opposite direction; applying it to the armrest 10 and the table board assembly 20 can realize the automatic unfolding of the table board body 202, and the overall structure is simple; and in the damping assembly, the mutual restraint between the first elastic part 08, the second elastic part 09 and the damping part 07 limits the sliding speed of the gear condition 05, which can control the rotation rate of the table board body 202, avoid the table board body 202 from being opened or closed instantly, and reduce the user's use risk.

[0070] In one embodiment, if Figure 4-Figure 6 As shown, the damping member 07 includes an elastic pull rope 71 and a hook member 72. One end of the elastic pull rope 71 is connected to the hook member 72 and locked in the base 03, and the other end passes through the blocking member 06 and the gear condition 05 in sequence and is fixed on the blocking member 06.

[0071] When the rack condition 05 is locked, the first elastic member 08 is compressed, and the elastic drawstring 71 is in a tensioned state to compress the second elastic member 09 and restrict the blocking member 06 from sliding. When the rack condition 05 is unlocked, the first elastic member 08 releases energy to push the rack condition 05 and the blocking member 06 to slide upward, and the elastic drawstring 71 is further tightened and further compresses the second elastic member 09. At this time, the blocking member 06 slides to the top of the slide groove 31.

[0072] When the trigger member 01 triggers the starter member 04 again, the hook member 72 is unlocked, the elastic pull rope 71 is released to trigger the second elastic member 09, and the second elastic member 09 releases energy to push the gear member 05 to slide downward.

[0073] Specifically, the elastic pull rope 72 is elastic, and when the hook member 71 is locked, the elastic pull rope 72 is in a tensioned state, thereby providing elastic force between the gear member 05, the blocking member 06 and the base 03 to limit the positional relationship of the three. Figure 4 , Figure 5 In the initial state shown, when the rack member 05 is locked, the rack member 05 compresses the first elastic member 08 , and the blocking member 06 compresses the second elastic member 09 under the elastic force of the elastic pull rope 72 .

[0074] When the gear condition 05 is unlocked, the first elastic member 08 releases energy to push the gear condition 05 to slide upward, and the gear condition 05 pushes the second elastic member 09 and the blocking member 06 to slide upward until the blocking member 06 slides to the top of the slide groove 31. During this process, the elastic pull rope 72 is further tightened, thereby limiting the speed at which the gear condition 05 slides upward and preventing the gear condition 05 from sliding too fast, thereby achieving a damping effect.

[0075] When the trigger member 01 triggers the starting member 04 again, the hook member 72 is unlocked, and the elastic pull rope 71 releases energy to unlock the second elastic member 09. At this time, the second elastic member 09 releases energy to push the gear condition 05 to slide downward in the reverse direction. During the downward sliding process of the gear condition 05, the first elastic member 08 is squeezed. The first elastic member 08 provides elastic force to slow down the sliding speed of the gear condition 05, and also achieves a damping effect.

[0076] In the embodiment of the present application, the damping member 07 is configured as an elastic pull rope 71 and is locked by a hook member 72, which not only realizes the coordination of the actuation process of the tooth condition 05 and the blocking member 06, but also realizes the damping effect in coordination with the first elastic member 08 and the second elastic member 09.

[0077] Alternatively, if Fig. 9 As shown, a damping gear 011 may be provided on one side of the rack member 05 to further limit the sliding speed of the rack member 05 and improve the damping effect.

[0078] In one embodiment, if Figure 4-Figure 8 As shown, the actuating assembly further includes a telescopic push rod 010 for being mounted on the sliding member, and a stopper 61 cooperating with the telescopic push rod 010 is provided on the blocking member 06;

[0079] The damping member 07 further includes a movable sleeve 73, one end of the elastic pull rope 71 is connected to the hook member 72, and the other end passes through the movable sleeve 73 and then passes through the blocking member 06 and the gear condition 05 in sequence before being fixed on the blocking member 06;

[0080] After the trigger member 01 triggers the starting member 04 again and drives the transmission gear set 02 to rotate in the opposite direction, the telescopic push rod 010 is controlled to extend, and the sliding member continues to slide down so that the telescopic push rod 101 cooperates with the block 61 to push the blocking member 06 to slide downward, and the blocking member 06 pushes the movable sleeve 73 to drive the hook member 72 to slide down until the hook member 72 is locked in the base 03. At this time, the telescopic push rod 010 is controlled to retract.

[0081] Specifically, the telescopic push rod 010 can be controlled to extend and retract using a solenoid valve, such as Figure 8As shown, after the sliding member slides down to the trigger member 01 and triggers the starter member 04 again, the telescopic push rod 010 is controlled to extend, so that the telescopic push rod 010 can cooperate with the block 61 to drive the blocking member 06 to slide downward as the sliding member slides down. When the blocking member 06 slides down to abut against the movable sleeve 73, as the sliding member continues to slide down, the blocking member 06 pushes the movable sleeve 73 and the hook member 72 to slide downward, so that the hook member 72 slides back into the mounting seat 32 and is locked again. After that, the telescopic push rod 010 is controlled to retract, so that the sliding member can continue to slide down and reset.

[0082] The embodiment of the present application is provided with a telescopic push rod 010 and a movable sleeve 73, so that after the hook member 72 is unlocked and the gear condition 05 is driven to reset, the blocking member 06 is pushed by the sliding member to reset the hook member 72, so that the damping assembly returns to the Figure 4 , Figure 5 The initial state is shown.

[0083] In one embodiment, if Figure 4-Figure 8 As shown, the gear member 05 is provided with a first shaft hole 51 and a first pulley 52, the blocking member 06 is provided with a second shaft hole 62 and a second pulley 63, and the movable sleeve 73 is installed in the first shaft hole 51;

[0084] One end of the elastic pull rope 71 is connected to the hook member 72 , and the other end passes through the movable sleeve 73 and the second shaft hole 62 and then passes around the second pulley 63 and the first pulley 52 in sequence and is fixed on the blocking member 06 .

[0085] Specifically, the first shaft hole 51 and the second shaft hole 62 are both arranged to penetrate in the up-down direction, and the axes of the first shaft hole 51 and the second shaft hole 62 are on the same straight line, the outer diameter of the movable sleeve 73 is smaller than the inner diameter of the first shaft hole 51, and the movable sleeve 73 can move freely in the first shaft hole 51. The first pulley 52 and the second pulley 63 are arranged on the same side, one end of the elastic pull rope 71 is connected to the hook member 72, and the other end passes through the movable sleeve 73 and the second shaft hole 62 in turn, and then continues to bypass the second pulley 63 and the first pulley 52 and is fixed on the blocking member 06. Among them, the outer diameter of the movable sleeve 73 is larger than the inner diameter of the second shaft hole 62 and smaller than the outer diameter of the hook member 72, so that the movable sleeve 73 can be abutted between the hook member 72 and the blocking member 06.

[0086] In one embodiment, if Figure 4-Figure 8 As shown, the base 03 is provided with an inner sleeve 33, the gear condition 05 is provided with a limiting sleeve 53, the limiting sleeve 53 is sleeved outside the inner sleeve 33, and the limiting sleeve 53 is provided with a limiting slot 531;

[0087] One end of the starter 04 is connected to the inner wall of the base 03 through a limit elastic member 41, and the other end extends out of the base 03 as a trigger end 43. The starter 04 is also provided with a limit block 42, which is inserted into the limit slot 531 to lock the gear condition 05;

[0088] When the trigger member 01 triggers the starter member 04 for the first time, the trigger member 01 pushes the trigger end 43 to make the starter member 04 compress the limit elastic member 41 , driving the limit block 42 to disengage from the limit slot 531 to unlock the gear condition 05 .

[0089] Specifically, the mounting seat 32 of the base 03 is provided with an inner sleeve 33, and the limiting sleeve 53 is sleeved outside the inner sleeve 33, which can limit the limiting sleeve 53 and guide the sliding of the gear condition 05. The starter 04 is sleeved outside the limiting sleeve 53 and the inner sleeve 33, one end of the starter 04 is pressed against the inner wall of the mounting seat 32 through the limiting elastic member 41, and the opposite trigger end 43 extends out of the mounting seat 32, and the limiting block 42 is set at one end connected to the limiting elastic member 41, and the limiting block 42 extends toward one side of the limiting sleeve 53. When the starter 04 is not pushed, the limiting block 42 is clamped into the limiting slot 531 under the elastic force of the limiting elastic member 41. When the trigger member 01 pushes the trigger end 43, the limiting elastic member 41 is compressed, and the limiting block 42 is disengaged from the limiting slot 531, thereby unlocking the gear condition 05.

[0090] In the embodiment of the present application, a limiting sleeve 53 is provided on the gear condition 05 , a limiting slot 531 is provided on the limiting sleeve 53 , and locking and unlocking of the gear condition 05 are achieved by actuating the limiting block 42 on the starting member 04 .

[0091] In one embodiment, if Figure 4-Figure 8 As shown, the rack condition 05 also includes a rack portion 54, in which a first axial hole 51 for mounting the damping member 07 is provided, and a first annular groove 55 for mounting the first elastic member 08 is provided on the outer side of the first axial hole 51, and an annular plate 56 is formed between the first axial hole 51 and the first annular groove 55, and a limiting sleeve 53 extends from the end of the annular plate 56.

[0092] Specifically, the outer surface of the rack portion 54 is provided with teeth meshing with the transmission gear set 02, the first shaft hole 51 is provided in the rack portion 54, and a first annular groove 55 is provided on the outer side of the first shaft hole 51 for installing the first elastic member 08, and the depth of the first annular groove 55 is specifically set according to the length of the first elastic member 08. The limiting sleeve 53 extends from the annular plate between the first shaft hole 51 and the first annular groove 55, and the structure of the entire rack portion 05 is compact, saving the space occupied by the damping component.

[0093] In one embodiment, if Figure 5-Figure 8As shown, the damping member 07 includes an elastic pull rope 71 and a hook member 72. One end of the elastic pull rope 71 is connected to the hook member 72. The wall of the inner sleeve 33 is provided with a clamping hole 331 and a spring piece 332 which are arranged oppositely. The spring piece 332 squeezes the hook member 72 and cooperates with the clamping hole 331.

[0094] A rotatable cam 44 is installed at the trigger end 43 of the starter 04. When the trigger 01 triggers the starter 04 for the first time, the swing end of the cam 44 swings against the outer wall of the limiting sleeve 53. When the trigger 01 triggers the starter 04 again, the starter 04 drives the cam 44 to push the spring 332 to unlock the hook 72.

[0095] Specifically, the locking hole 331 is opened on the wall of the inner sleeve 33, the spring piece 332 is installed on the inner wall of the inner sleeve 33 and extends toward one side of the locking hole 331. When the hook member 72 is installed between the locking hole 331 and the spring piece 332, it will cooperate with the locking hole 331 under the pressure of the spring piece 332, thereby locking the hook member 72.

[0096] A rotatable cam 44 is installed below the trigger end 43 of the starter 04, and a torsion spring is connected between the cam 44 and the trigger end 43. Under the action of the torsion spring, the cam 44 has a tendency to rotate toward the trigger end 43.

[0097] like Figure 5 , Figure 7 As shown, during the process of the gear condition 05 being locked, the limiting sleeve 53 is inserted into the inner sleeve 33 to push the swing end of the cam 44 so that the cam 44 overcomes the torsion force of the torsion spring and rotates to the side away from the trigger end 43, until the gear condition 05 is locked, and the swing end of the cam 44 abuts against the outer wall of the limiting sleeve 53. Figure 6 As shown, when the gear condition 05 is unlocked, the limiting sleeve 53 disengages from the inner sleeve 33, and the cam 44 rotates toward the trigger end 43 under the action of the torsion spring and remains in a horizontal state. At this time, as the sliding member drives the trigger member 01 to slide downward, the trigger member 01 pushes the starting member 04, driving the cam 44 to move toward one side of the inner sleeve 53, and the cam 44 pushes the spring piece 332 away from the locking hole 331, thereby unlocking the hook member 72.

[0098] The embodiment of the present application realizes locking of the hook member 72 by setting a locking hole 331 and a spring piece 332 in the inner sleeve 33, and by setting a rotatable cam 44 on the starting member 04, it is possible to unlock the gear condition 05 when the starting member 04 is triggered for the first time, and unlock the hook member 72 when it is triggered again. The overall structure is simple and ingenious.

[0099] In one embodiment, if Figure 4-Figure 8As shown, the blocking member 06 is provided with a second shaft hole 62 for installing the damping member 07, the outer side of the second shaft hole 62 is provided with a second annular groove 64 for installing the second elastic member 09, and the upper end of the gear condition 05 is provided with a third annular groove 57;

[0100] One end of the second elastic member 09 is installed in the second annular groove 64 , and the other end is installed in the third annular groove 57 .

[0101] Specifically, the blocking member 06 is provided with a second annular groove 64 on the outer side of the second shaft hole 62 for installing the second elastic member 09, the depth of the second annular groove 64 is set according to the length of the second elastic member 09, and a third annular groove 57 is provided at the upper end of the tooth condition 05, and the two ends of the second elastic member 09 are respectively installed in the second annular groove 64 and the third annular groove 57.

[0102] Figure 1-Figure 8 A preferred embodiment of the transmission damping structure of the present application is provided. Figure 1-Figure 8 The structure shown in the figure explains the operation process of the transmission damping structure:

[0103] like Figure 5 As shown, the damping assembly is in the initial state, the sliding member drives the trigger member 01 to slide to push the starting member 04, the starting member 04 compresses the limit elastic member 41 to move, the limit block 42 in the starting member 04 is separated from the limit slot 531 in the limit sleeve 53, thereby unlocking the gear condition 05, and the gear condition 05 slides upward under the elastic force of the first elastic member 08, and the gear condition 05 drives the transmission gear set 02 meshing therewith to rotate forward when sliding upward. In this process, the damping member 07 provides a damping force to limit the sliding speed of the gear condition 05, and at the same time drives the second elastic member 09 and the blocking member 06 to slide upward until the blocking member 06 slides to the uppermost end of the slide groove 31. In addition, as the gear condition 05 is unlocked, the cam 44 on the starting member 04 rotates to a horizontal state, and the transmission damping structure is in Figure 6 Then, as the sliding member slides downward, the trigger member 01 is driven to slide downward until the start member 04 is triggered again. The start member 04 drives the cam 44 to actuate until the cam pushes the spring sheet 332, thereby unlocking the hook member 72. The elastic pull rope 71 releases energy and shortens. At this time, the second elastic member 09 is released to push the gear member 05 to slide downward. The gear member 05 drives the transmission gear set 02 to slide in the opposite direction. The gear member 05 compresses the first elastic member 08 during the sliding process. The first elastic member 08 limits the sliding speed of the gear member 05. In addition, during the downward sliding process of the gear member 05, the limiting sleeve 53 drives the cam 44 to rotate so that the cam 44 rotates back to the initial state. At this time, the transmission damping structure is in Figure 7Afterwards, the sliding member continues to drive the trigger member 01 to slide down, and at the same time controls the telescopic push rod 010 to extend, so that the telescopic push rod 010 can cooperate with the block 61 to drive the blocking member 06 to slide down. When the blocking member 06 slides down to contact the movable sleeve 73, as the sliding member continues to slide down, the blocking member 06 pushes the movable sleeve 73 and the hook member 72 to slide down, so that the hook member 72 slides back into the mounting seat 32 and is re-locked by the spring piece 332 and the clamping hole 331. At this time, the transmission damping structure is in Figure 8 The state shown in the figure is then controlled to retract the telescopic push rod 010 so that the sliding member can continue to slide down and reset. At this time, the blocking member 06 slides upward for a certain distance until the elastic forces of the second elastic member 09 and the elastic pull rope 71 reach a balance. At this time, the transmission damping structure is restored to Figure 6 The initial state is shown.

The trigger member 01 of the transmission damping structure is installed on the sliding plate 201, the transmission gear set 02 is installed on the tabletop shaft, and the damping assembly is installed on the armrest 10.

[0109] Specifically, the table board body 202 is rotatably mounted above the sliding plate 201. In the initial state, the table board body 202 and the sliding plate 201 are on the same plane. The driving device 203 drives the sliding plate 201 to drive the table board body 202 to slide upward until the transmission gear set 02 cooperates with the damping assembly. The driving device 203 continues to drive the sliding plate 201 to slide upward, and the sliding plate 201 drives the table board body 202 to rotate and unfold through the damping assembly and the transmission gear set 02. By setting the transmission ratio of the transmission gear set 02, after the gear condition 05 in the damping assembly completes a sliding stroke, the table board shaft rotates 90° to rotate the table board body 202 from a vertical state to a horizontal state.

[0110] The armrest table top of the embodiment of the present application has a simple overall structure, and the automatic unfolding of the table top body is achieved through the transmission damping structure, and the unfolding speed of the table top body can be limited, thereby preventing the table top body from falling quickly and affecting the user experience.
