Description

Technical Field

[0001] The present application relates to the field of furniture technology, and in particular to a kind of rhythmic furniture. Background Art

[0002] Rhythmic furniture generally consists of a base, a bracket, and a drive mechanism. The base is typically placed on the ground for support, while the bracket is mounted above the base. The drive mechanism is connected to the bracket, driving the bracket to perform reciprocating motion. Rhythmic motion refers to the reciprocating motion of the bracket. Depending on the direction of the bracket's rhythmic motion, it can be categorized as horizontal rhythmic or vertical rhythmic. In the related art of vertical rhythmic furniture, the furniture includes a drive mechanism and a connecting rod with a through hole in the middle. The connecting rod is configured to rotate about the hole. The output shaft of the drive mechanism reciprocates vertically. The output shaft is connected to one end of the connecting rod, driving the other end of the connecting rod to rotate vertically about the hole. The other end of the connecting rod is connected to the bracket, causing the bracket to reciprocate vertically, thus achieving vertical reciprocating motion of the rhythmic furniture. In the related art, the vertical reciprocating motion of the output shaft requires a certain vertical height between the bracket and the base, resulting in a high center of gravity for the bracket, which is less stable during high-frequency up-and-down reciprocating motion. Summary of the Invention

[0003] The embodiments of the present application provide a rhythmic furniture to at least solve the technical problem of instability caused by the high center of gravity of the existing rhythmic furniture that reciprocates up and down.

[0004] The present application provides a rhythmic furniture, including:

[0005] Fixed frame;

[0006] Rhythm rack;

[0007] The first connecting mechanism and the second connecting mechanism are arranged opposite to each other, and each of the first connecting mechanism and the second connecting mechanism includes a first rotating rod and two first connecting members, the two first connecting members are arranged corresponding to each other, each of the first rotating rods is rotatably connected to the fixed frame, one end of each of the two first connecting members is fixedly connected to the first rotating rod, and the two first connecting members extend along the radial direction of the first rotating rod, and the other ends of the two first connecting members are rotatably connected to the rhythm frame;

[0008] A driving mechanism, comprising a driving member, configured to cause the driving member to output at least reciprocating motion in a horizontal direction, wherein the driving member is eccentrically connected to the first rotating rod of the first connecting mechanism so as to convert the horizontal motion output by the driving member into rotational motion of the first rotating rod of the first connecting mechanism.

[0009] The rhythmic furniture according to the embodiments of the present application has at least the following beneficial effects:

[0010] The rhythmic furniture of the embodiment of the present application converts the horizontal movement of the driving member into the vertical movement of the rhythm frame, so that the space occupied by the driving member in height is reduced, and less space is reserved for the driving member between the rhythm frame and the fixed frame in the height direction, thereby lowering the center of gravity of the rhythm frame, so that the rhythmic furniture has better stability during the high-frequency reciprocating movement.

[0011] In one possible embodiment, the first connecting mechanism further includes a first elastic connector, one end of which is fixedly connected to the driving member, and the other end of which is fixedly connected to a circumferential side wall of the first rotating rod of the first connecting mechanism. The horizontal plane where the end of the driving member connected to the first elastic connector lies is at a different vertical height than the horizontal plane where the axis of the first rotating rod lies. The first elastic connector can provide a buffering effect when the positions of the driving member and the first rotating rod change periodically, thereby reducing the user's sense of jerkiness when the rhythmic furniture transitions up and down, thereby improving the user experience.

[0012] In one possible embodiment, the first elastic connector includes an elastic sheet, a first fixing member, and a second fixing member. At least a portion of the elastic sheet overlaps with the vertical projection of the first rotating rod of the first connecting mechanism. The first fixing member is disposed between the elastic sheet and the first rotating rod of the first connecting mechanism to connect the elastic sheet and the first rotating rod. The second fixing member is used to connect the driving member to the elastic sheet. The first fixing member and the second fixing member connect the elastic sheet to the driving member and the first rotating rod of the first connecting mechanism, respectively, thereby ensuring a more stable structure of the elastic member during operation of the motion-controlled furniture.

[0013] In one possible embodiment, the first fixing member includes a protrusion, and the first rotating rod of the first connecting mechanism includes a recess, with the protrusion mating with the recess. The protrusion and recess cooperate to secure the first rotating rod to the first fixing member, thereby making the connection between the first fixing member and the first rotating rod of the first connecting mechanism more secure, thereby reducing loosening and slipping during operation of the motion-activated furniture.

[0014] In one possible embodiment, the first and second connecting mechanisms each further include two second connecting members and a second rotating rod. The second rotating rod is disposed through the two first connecting members and is rotatably connected to the two first connecting members. One end of the two second connecting members is fixedly connected to the second rotating rod, and the other end is fixedly connected to the rhythm frame, thereby achieving a rotatable connection between the first connecting members and the rhythm frame. The second rotating rod enhances the structural strength of the first and second connecting mechanisms, thereby providing greater stability for the rhythmic furniture during high-frequency up and down reciprocating motion.

[0015] In a possible embodiment, the first rotating rod is connected to the fixed frame via a bearing, and the second rotating rod is connected to the two first connecting members and the two second connecting members via a bearing. The bearing connection makes the rotational movement smoother.

[0016] In a possible embodiment, the bearing connection is a connection via a rubber-coated bearing. By providing the rubber-coated bearing, the noise during the rotational movement between the corresponding components is reduced, thereby improving the user's pleasant experience.

[0017] In one possible embodiment, the rhythmic furniture further includes a linkage mechanism, each connected to the first rotating rod of the first connecting mechanism and the first rotating rod of the second connecting mechanism. This linkage mechanism enables the first rotating rod of the second connecting mechanism to rotate when the first rotating rod of the first connecting mechanism rotates. The linkage mechanism transmits the rotational motion of the first rotating rod of the first connecting mechanism to the first rotating rod of the second connecting mechanism, ensuring consistent vertical motion of the overall rhythmic frame. Furthermore, the linkage mechanism transmits force while also transmitting rotational motion, allowing the rhythmic frame to handle a greater load.

[0018] In one possible embodiment, the linkage mechanism includes a linkage, a second elastic connector, and a third elastic connector. One end of the linkage is fixedly connected to the first rotating rod of the first connecting mechanism via the second elastic connector, and the other end of the linkage is fixedly connected to the first rotating rod of the second connecting mechanism via the third elastic connector. The provision of the second and third elastic connectors can reduce the user's sense of jerkiness when the rhythmic furniture transitions up and down, thereby enhancing the user experience.

[0019] In one possible embodiment, the rhythmic furniture further includes a linkage mechanism, comprising a linkage member, each of which connects the drive mechanism and the first rotating rod of the second connecting mechanism. The drive mechanism is configured to cause the linkage member to output at least horizontal reciprocating motion, thereby converting the horizontal motion output by the drive mechanism into rotational motion of the first rotating rod of the second connecting mechanism. The connection between the drive mechanism and the linkage member allows for more synchronized motion between the first rotating rod of the first connecting mechanism and the first rotating rod of the second connecting mechanism, thereby further synchronizing the motion of the various components of the rhythmic frame.

[0040] The following combination Figures 1 to 8The rhythmic furniture according to the embodiment of the present application is described in detail.

[0041] The present application embodiment provides a rhythmic furniture, such as Figure 1 and Figure 2 As shown, the apparatus includes a fixed frame 100, a rhythm frame 200, a first connecting mechanism 300a and a second connecting mechanism 300b arranged opposite to each other, and a driving mechanism 400. The first connecting mechanism 300a and the second connecting mechanism 300b each include a first rotating rod 310 and two first connecting members 320. The two first connecting members 320 are arranged corresponding to each other. Each first rotating rod 310 is rotatably connected to the fixed frame 100. One end of each first connecting member 320 is fixedly connected to the first rotating rod 310, and the two first connecting members 320 extend in the radial direction of the first rotating rod 310. The other end of the two first connecting members 320 is rotatably connected to the rhythm frame 200. The driving mechanism 400 includes a driving member 410, which is used to enable the driving member 410 to output at least reciprocating motion in the horizontal direction. The driving member 410 is eccentrically connected to the first rotating rod 310 of the first connecting mechanism 300a so as to convert the horizontal motion output by the driving member 410 into the rotational motion of the first rotating rod 310 of the first connecting mechanism 300a.

[0042] Please combine Figure 3 and Figure 4 Regarding the connection relationship of the first connecting mechanism 300a, the driving member 410 is eccentrically connected to the first rotating rod 310. The driving member 410 outputs a torque tangentially to the first rotating rod 310, causing the first rotating rod 310 to rotate. The first connecting member 320 connected to the first rotating rod 310 also rotates accordingly. The end of the first connecting member 320 distal from the first connecting rod rotates along the axis of the first rotating rod 310, resulting in vertical movement of the end of the first connecting member 320 distal from the first connecting rod. Because the first connecting member 320 is rotatably connected to the rhythm frame 200, it drives the rhythm frame in vertical motion. Furthermore, because the driving member 410 reciprocates, the vertical motion of the rhythm frame 200, after passing through the first rotating rod 310 and the first connecting member 320, is also reciprocating.

[0043] By converting the horizontal movement of the driving member 410 into the vertical movement of the rhythm frame 200, the height space occupied by the driving member 410 is reduced, and less space is reserved for the driving member 410 in the height direction between the rhythm frame 200 and the fixed frame 100, thereby lowering the center of gravity of the rhythm frame 200, so that the rhythm furniture has better stability during the high-frequency up and down reciprocating motion.

[0044] It can be understood that the eccentric connection between the driving member 410 and the first rotating rod 310 means that the horizontal plane where the driving member 410 moves in the horizontal direction and the horizontal plane where the axis of the first rotating rod 310 is located are staggered in the vertical direction.

[0045] It is understandable that if Figure 2 As shown, the fixed frame 100 and the rhythm frame 200 are both roughly rectangular in shape, and the sizes of the fixed frame 100 and the rhythm frame 200 are also corresponding. The rhythm frame 200 is generally arranged above the fixed frame 100, and the fixed frame 100 is placed on the ground. The rhythm frame 200 is used for users to sit on.

[0046] like Figure 1 As shown, in the horizontal direction, the fixing frame 100 is divided into a front portion and a rear portion, and the front portion and the rear portion are distinguished only by their position. The first connecting mechanism 300a is disposed at the front portion of the fixing frame 100, and the second connecting mechanism 300b is disposed at the rear portion of the fixing frame 100. The specific positions of the front and rear portions correspond to each other. Here, corresponding means that the positions of the first connecting mechanism 300a and the second connecting mechanism 300b are the same in the left-right direction. For example, the distance between the first connecting mechanism 300a and the left side of the fixing frame 100 is the same as the distance between the second connecting mechanism 300b and the left side of the fixing frame 100.

[0047] In some embodiments, as Figure 3 As shown, the first rotating rod 310 is cylindrical in shape, and the fixing frame 100 further includes a connecting base 110. Both ends of the first rotating rod 310 are rotatably connected to the connecting base 110, and there are four connecting bases 110. It is understood that the connecting bases 110 of the fixing frame 100 are respectively provided at the first connecting mechanism 300a and the second connecting mechanism 300b.

[0048] In some embodiments, as Figure 3 and Figure 4 As shown, the two first connecting members 320 are respectively arranged at the two opposite ends of the first rotating rod 310, so that the overall structural strength of the rhythmic furniture is higher and the rhythmic frame 200 has better stability during the high-frequency up and down reciprocating motion.

[0049] In some embodiments, please refer to Figure 3 and Figure 4 The two first connecting members 320 are located between the two connecting seats 110, which makes the first connecting members 320 occupy a smaller space in the horizontal direction, which is conducive to controlling the overall size of the rhythmic furniture. In some embodiments, the first connecting member 320 is connected to the first rotating rod 310 in a fixed connection, and the relative position between the two remains unchanged, so that when the first rotating rod 310 rotates, the first connecting member 320 also rotates. In some embodiments, please refer to Figure 5 The first rotating rod 310 is inserted into the first connecting member 320, and the first rotating rod 310 and the first connecting member 320 are fixed to each other by a concave-convex fit. In some embodiments, the first rotating rod 310 and the first connecting member 320 are connected by a keyway. In some embodiments, at the connection between the first rotating rod 310 and the first connecting member 320, the circumferential sidewall of the first rotating rod 310 is recessed inward, and the first connecting member 320 has a corresponding protrusion. The recess and protrusion cooperate to limit the relative displacement between the first connecting member 320 and the first rotating rod 310.

[0050] In some embodiments, as Figure 6 and Figure 7 As shown, the first connecting mechanism 300a also includes a first elastic connecting member 340, one end of the first elastic connecting member 340 is fixedly connected to the driving member 410, and the other end of the first elastic connecting member 340 is fixedly connected to the circumferential side wall of the first rotating rod 310 of the first connecting mechanism 300a, and the horizontal plane where the end of the driving member 410 connected to the first elastic connecting member 340 is located is different in height in the vertical direction from the horizontal plane where the axis of the first rotating rod 310 is located.

[0051] It is understood that the first rotating rod 310 rotates relative to the fixed frame 100, i.e., the first rotating rod 310 does not undergo any displacement in the vertical or horizontal directions, while the driving member 410 reciprocates in the horizontal direction, i.e., the driving member 410 undergoes any displacement in the horizontal direction, and the relative positions of the driving member 410 and the first rotating rod 310 change in the horizontal direction. The first elastic connector 340 is used to connect the driving member 410 and the first rotating rod 310, and the first elastic connector 340 adapts to the positional changes between the two by changing its own elasticity. The horizontal plane where the end of the driving member 410 connected to the first elastic connecting member 340 is located is different from the horizontal plane where the axis of the first rotating rod 310 is located in the vertical direction, resulting in different heights at the two ends of the first elastic connecting member 340. When the driving member 410 moves in the horizontal direction, the driving member 410 drives the first elastic connecting member 340 to move in the horizontal direction, so that the end of the first elastic connecting member 340 connected to the first rotating rod 310 has a horizontal movement tendency toward the other end, that is, the first elastic connecting member 340 applies its tangential force to the first rotating rod 310. Since the first rotating rod 310 cannot move in the horizontal direction but can rotate around itself, the original horizontal movement tendency of the end of the first elastic member connected to the first rotating rod 310 is changed to a vertical movement tendency, thereby allowing the first rotating rod 310 to rotate around itself under the pull of the first elastic connecting member 340. The first elastic connecting member 340 can play a certain buffering role when the position between the driving member 410 and the first rotating rod 310 changes periodically, so that the user feels less frustration when the rhythmic furniture changes direction up and down, thereby improving the user's experience.

[0052] In some embodiments, the driving member 410 includes a rack, and the circumferential side wall of the first rotating rod 310 includes gear teeth distributed along the circumference. The horizontal plane where the rack is located is different from the horizontal plane where the axis of the first rotating rod 310 is located, and the rack and the gear teeth are meshed and connected to convert the horizontal motion output by the driving member 410 into the rotational motion of the first rotating rod 310.

[0053] In some embodiments, the first elastic connector 340 includes an elastic sheet 341, a first fixing member 342, and a second fixing member 343. At least a portion of the elastic sheet 341 overlaps with the vertical projection of the first rotating rod 310 of the first connecting mechanism 300a. The first fixing member 342 is disposed between the elastic sheet 341 and the first rotating rod 310 of the first connecting mechanism 300a to connect the elastic sheet 341 and the first rotating rod 310. The second fixing member 343 is used to connect the driving member 410 to the elastic sheet 341. The first fixing member 342 and the second fixing member 343 respectively connect the elastic sheet 341 to the driving member 410 and the first rotating rod 310 of the first connecting mechanism 300a, thereby making the elastic member more structurally stable during the operation of the rhythmic furniture.

[0054] In some embodiments, the end portion of the elastic piece 341 connected to the first rotating rod 310 of the first connecting mechanism 300 a is located above or below the first rotating rod 310 , which is not specifically limited.

[0055] In some embodiments, the first fixing member 342 includes a protrusion, and the first rotating rod 310 of the first connecting mechanism includes a recess, with the protrusion mating with the recess. The connection between the first fixing member 342 and the first rotating rod 310 includes a recessed-protrusion connection. At the connection between the first rotating rod 310 and the first fixing member 342, the circumferential sidewall of the first rotating rod 310 is recessed inward, and the first fixing member 342 correspondingly protrudes outward. The recessed and protruded portions cooperate to secure the first rotating rod 310 and the first fixing member 342, thereby making the connection between the first fixing member 342 and the first rotating rod 310 of the first connecting mechanism 300a more secure, thereby reducing loosening and slipping during the operation of the rhythmic furniture.

[0056] In some embodiments, the protruding portion of the first fixing member 342 is a slot key, and the recessed portion of the first rotating rod 310 of the first connecting mechanism is a key slot, and the two cooperate with each other.

[0057] In some embodiments, the connection between the first fixing member 342 and the first rotating rod 310 of the first connecting mechanism 300a can also be achieved by gear tooth engagement. The first fixing member 342 is provided with a through hole, and the inner wall of the through hole is provided with gear teeth along its circumferential direction. The circumferential side wall of the first rotating rod 310 of the first connecting mechanism 300a is provided with gear teeth. The two gear teeth are engaged with each other, and the first rotating rod 310 of the first connecting mechanism 300a is inserted into the through hole of the first fixing member 342, so that the first rotating rod 310 of the first connecting mechanism 300a does not rotate along its circumference relative to the first fixing member 342 when it is in the through hole.

[0058] In some embodiments, please combine Figure 3 、 Figure 4 and Figure 5 The first connecting mechanism 300a and the second connecting mechanism 300b each further include a second rotating rod 350 and two second connecting members 330. The second rotating rod 350 passes through the two first connecting members 320 and is rotatably connected to the two first connecting members 320. One end of the two second connecting members 330 is fixedly connected to the second rotating rod 350, and the other end is fixedly connected to the rhythm frame 200, thereby achieving a rotatable connection between the first connecting members 320 and the rhythm frame 200. The second rotating rod 350 and the two second connecting members 330 enhance the structural strength of the first connecting mechanism 300a and the second connecting mechanism 300b, thereby providing greater stability for the rhythmic furniture during high-frequency up and down reciprocating motion.

[0059] In some embodiments, as Figure 5 As shown, the first rotating rod 310 is connected to the fixing frame 100 via a bearing 360, and the second rotating rod 350 is connected to the two first connecting members 320 and the two second connecting members 330 via bearings 360. The connection via the bearings 360 makes the aforementioned parts smoother when rotating.

[0060] In some embodiments, the bearing 360 is connected by a rubber-coated bearing 360. By providing the rubber-coated bearing 360, the noise during the rotational movement between the corresponding components is reduced, thereby improving the user's pleasant experience.

[0061] In some embodiments, please combine Figure 1 and Figure 6 As shown, the rhythmic furniture also includes a linkage mechanism 500, which is connected to the first rotating rod 310 of the first connecting mechanism 300a and the first rotating rod of the second connecting mechanism 300b, respectively. This allows the first rotating rod 310 of the first connecting mechanism 300a to rotate, driving the first rotating rod of the second connecting mechanism 300b to rotate as well. The linkage mechanism 500 transmits the rotational motion of the first rotating rod 310 of the first connecting mechanism 300a to the first rotating rod of the second connecting mechanism 300b, ensuring consistent vertical motion of the entire rhythmic frame 200. Furthermore, the linkage mechanism 500 not only transmits rotational motion but also forces, allowing the rhythmic frame 200 to withstand a greater load.

[0062] In some embodiments, the linkage mechanism 500 includes a linkage 510, a second elastic connector 520, and a third elastic connector 530. One end of the linkage 510 is fixedly connected to the first rotating rod 310 of the first connecting mechanism 300a via the second elastic connector 520, and the other end of the linkage 510 is fixedly connected to the first rotating rod of the second connecting mechanism 300b via the third elastic connector 530. The provision of the second elastic connector 520 and the third elastic connector 530 can reduce the user's sense of jerkiness when the rhythmic furniture transitions up and down, thereby improving the user experience.

[0063] In some embodiments, the linkage mechanism 500 includes a chain connected at both ends and two annular gears, the two annular gears being fixedly mounted on the first rotating rod 310 of the first connecting mechanism 300a and the first rotating rod of the second connecting mechanism 300b, and the positions of the two annular gears correspond to each other, the chain is wrapped around the two annular gears, and the chain is engaged with the two annular gears so that when the annular gear installed on the first rotating rod 310 of the first connecting mechanism 300a rotates, it drives the rack to move, thereby driving the annular gear installed on the first rotating rod of the second connecting mechanism 300b to rotate, thereby driving the first rotating rod of the second connecting mechanism 300b to rotate.

[0064] In some embodiments, the connecting member 510 and the driving member 410 extend in the same direction, and the two are arranged along the axial direction of the first rotating rod 310 to free up more space between the rhythm frame 200 and the fixed frame 100 to place the driving mechanism 400, thereby making the rhythm furniture more compact as a whole.

[0065] In some embodiments, see Figure 6 The driving member 410 and the connecting member 510 are sheet-like structures. On the one hand, the sheet-like structure is wider in the width direction, thereby increasing its structural strength in the width direction to meet the structural strength requirements of the driving member 410 and the connecting member 510 for reciprocating motion in the horizontal direction; on the other hand, the sheet-like structure is thinner in height, thereby reducing the space occupied in height and reducing the overall height of the rhythmic furniture to lower its center of gravity.

[0066] In some embodiments, as Figure 8As shown, the rhythmic furniture also includes a linkage mechanism 500, which includes a linkage member 510. The linkage member 510 connects the drive mechanism 400 and the first rotating rod of the second connecting mechanism 300b, respectively. The drive mechanism 400 is configured to cause the linkage member 510 to output at least horizontal reciprocating motion, thereby converting the horizontal motion output by the drive mechanism 400 into rotational motion of the first rotating rod of the second connecting mechanism 300b. The connection between the drive mechanism 400 and the linkage member 510 further synchronizes the motion between the first rotating rod 310 of the first connecting mechanism 300a and the first rotating rod of the second connecting mechanism 300b, thereby further synchronizing the motion of the various parts of the rhythm frame 200. The various parts of the rhythm frame 200 refer to the parts of the rhythm frame 200 corresponding to the first connecting mechanism 300a and the second connecting mechanism 300b, respectively.

[0067] In some embodiments, the drive mechanism 400 includes a motor and a conversion mechanism. The motor outputs rotational motion, and the conversion mechanism converts the rotational motion output by the motor into reciprocating motion including at least a horizontal direction. The conversion mechanism is in driving connection with the driving member 410 to transmit the converted horizontal reciprocating motion to the first rotating rod 310 of the first connecting mechanism 300a. It will be understood that conversion mechanisms that convert the rotational motion output by a motor into reciprocating motion including at least a horizontal direction are common, such as a rack and pinion mechanism, a crank slider mechanism, an oscillating push rod disc cam mechanism, etc.

[0068] In some embodiments, the driving member 410 and the conversion mechanism are staggered in the vertical direction, that is, the driving member 410 is located on the side of the conversion mechanism, rather than above or below it. This can reduce the height occupancy of the driving member 410 and the conversion mechanism, thereby lowering the overall center of gravity of the rhythmic furniture, allowing the rhythmic furniture to maintain stability during high-frequency up and down reciprocating motion.
