Description

Technical Field

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

[0002] Rhythmic furniture generally includes a base, a bracket and a driving mechanism. The base is generally placed on the ground to play a supporting role. The bracket is arranged above the base. The driving mechanism is connected to the bracket to drive the bracket to reciprocate. The rhythm refers to the reciprocating motion of the bracket. According to the direction of the rhythmic motion of the bracket, it can be divided into horizontal rhythm and up and down rhythm. In the related art of up and down rhythmic furniture, the rhythmic furniture includes a driving mechanism and a connecting rod. The middle part of the connecting rod has a through hole, and the connecting rod is configured to rotate around the through hole in the middle; the output shaft output by the driving mechanism reciprocates in the vertical direction, and the output shaft is connected to one end of the connecting rod, thereby driving the other end of the connecting rod to rotate around the through hole in the vertical direction, and the other end of the connecting rod is connected to the bracket, so that the bracket reciprocates up and down in the vertical direction, thereby realizing the up and down reciprocating motion of the rhythmic furniture in the vertical direction. In the related art, the output shaft outputs reciprocating motion in the vertical direction, so that a certain height needs to be reserved between the bracket and the base in the vertical direction, so that the center of gravity of the bracket is higher, and the stability of the bracket is insufficient when the bracket reciprocates up and down at a high frequency. Summary of the invention

[0003] The embodiment of the present application provides 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 embodiment 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 comprises a first rotating rod and two first connecting members, and 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 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, wherein the driving mechanism is used to enable the driving member to output at least reciprocating motion in a horizontal direction, and 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 a rotational motion of the first rotating rod of the first connecting mechanism.

[0009] The rhythmic furniture according to the embodiment 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 high-frequency up and down reciprocating motion.

[0011] In a possible embodiment, the first connection mechanism further includes a first elastic connection member, one end of which is fixedly connected to the driving member, and the other end of which is fixedly connected to the circumferential side wall of the first rotating rod of the first connection mechanism, and the horizontal plane where the end of the driving member connected to the first elastic connection member is located is at a different height in the vertical direction from the horizontal plane where the axis of the first rotating rod is located. The first elastic connection member can play a certain buffering role when the position between the driving member and the first rotating rod changes periodically, so that the user feels less frustration when the rhythmic furniture changes up and down, thereby improving the user's experience.

[0012] In a possible implementation, the first elastic connecting member includes an elastic sheet, a first fixing member and a second fixing member, at least a portion of the elastic sheet overlaps with the projection of the first rotating rod of the first connecting mechanism in the vertical direction, 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, and the second fixing member is used to connect the driving member and the elastic sheet. The elastic sheet is connected to the driving member and the first rotating rod of the first connecting mechanism respectively by the first fixing member and the second fixing member, so that the elastic member has a more stable structure during the operation of the rhythmic furniture.

[0013] In a possible implementation, the first fixing member includes a protrusion, and the first rotating rod of the first connecting mechanism includes a recessed portion, and the protrusion cooperates with the recessed portion. The protrusions and recesses of the two cooperate to fix the first rotating rod and the first fixing member, so that the connection between the first fixing member and the first rotating rod of the first connecting mechanism is more secure, and during the operation of the rhythmic furniture, looseness, sliding, etc. are reduced.

[0014] In a possible implementation, the first connection mechanism and the second connection mechanism each further include two second connection members and a second rotating rod, the second rotating rod being inserted through the two first connection members, the second rotating rod being rotatably connected to the two first connection members, one end of the two second connection members being fixedly connected to the second rotating rod, and the other end being fixedly connected to the rhythm frame, so as to realize a rotatable connection between the first connection member and the rhythm frame. The second rotating rod is used to enhance the structural strength of the first connection mechanism and the second connection mechanism, so that the rhythm furniture has better stability in high-frequency up and down reciprocating motion.

[0015] In a possible implementation manner, the first rotating rod is connected to the fixing 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.

[0017] In a possible implementation, the rhythmic furniture further includes a linkage mechanism, which is respectively connected to the first rotating rod of the first connecting mechanism and the first rotating rod of the second connecting mechanism, so that when the first rotating rod of the first connecting mechanism rotates, the first rotating rod of the second connecting mechanism is driven to rotate. The rotational motion of the first rotating rod of the first connecting mechanism is transmitted to the first rotating rod of the second connecting mechanism through the linkage mechanism, so that the overall up and down motion of the rhythmic frame remains consistent. At the same time, the linkage mechanism transmits the force while transmitting the rotational motion, so that the rhythmic frame has a larger load.

[0018] In a possible implementation, 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 through the second elastic connector, and the other end of the linkage is fixedly connected to the first rotating rod of the second connecting mechanism through the third elastic connector. By providing the second elastic connector and the third elastic connector, the user can feel less frustration when the rhythmic furniture changes direction up and down, thereby improving the user's experience.

[0019] In a possible embodiment, the rhythmic furniture further includes a linkage mechanism, the linkage mechanism includes a linkage member, the linkage member is respectively connected to the first rotating rod of the driving mechanism and the second connecting mechanism, and the driving mechanism is used to make the linkage member at least output reciprocating motion in the horizontal direction, so as to convert the horizontal motion output by the driving mechanism into the rotational motion of the first rotating rod of the second connecting mechanism. By connecting the driving mechanism with the linkage member, the first rotating rod of the first connecting mechanism and the first rotating rod of the second connecting mechanism move more synchronously, thereby making the movements of various parts of the rhythmic frame more synchronous.

[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, it 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 the two first connecting members 320 is fixedly connected to the first rotating rod 310, and the two first connecting members 320 extend along the radial direction of the first rotating rod 310, and 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 make the driving member 410 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 As for the connection relationship of the first connection mechanism 300a, the driving member 410 is eccentrically connected to the first rotating rod 310, and the driving member 410 outputs a torque along the tangential direction of the first rotating rod 310 to the first rotating rod 310, so that the first rotating rod 310 rotates, and the first connecting member 320 connected to the first rotating rod 310 also rotates accordingly, and the end of the first connecting member 320 away from the first connecting rod rotates along the axis of the first rotating rod 310, that is, the end of the first connecting member 320 away from the first connecting rod moves in the vertical direction. Because the first connecting member 320 is rotatably connected to the rhythm frame 200, the rhythm frame is driven to move in the vertical direction. Because the driving member 410 is reciprocating, after passing through the first rotating rod 310 and the first connecting member 320, the movement of the rhythm frame 200 in the vertical direction is also reciprocating.

[0043] By converting the horizontal movement of the driving member 410 into the vertical movement of the rhythm frame 200, the space occupied by the driving member 410 in height is reduced, so that 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 shapes of the fixing frame 100 and the rhythm frame 200 are both roughly rectangular, and the sizes of the fixing frame 100 and the rhythm frame 200 are also corresponding. The rhythm frame 200 is generally arranged above the fixing frame 100, and the fixing 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 part and a rear part, and the front part and the rear part are distinguished only in position. The first connecting mechanism 300a is arranged at the front part of the fixing frame 100, and the second connecting mechanism 300b is arranged at the rear part of the fixing frame 100, and the specific positions of the front part and the rear part correspond to each other. Here, corresponding means that the positions where the first connecting mechanism 300a and the second connecting mechanism 300b are arranged 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 equal to the distance between the second connecting mechanism 300b and the left side of the fixing frame 100.

[0047] In some embodiments, Figure 3 As shown, the first rotating rod 310 is in the shape of a cylinder, and the fixing frame 100 further includes a connecting seat 110. Both ends of the first rotating rod 310 are rotatably connected to the connecting seat 110, and the number of the connecting seats 110 is 4. It can be understood that the connecting seats 110 of the fixing frame 100 are respectively arranged at the first connecting mechanism 300a and the second connecting mechanism 300b.

[0048] In some embodiments, 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 rhythm furniture is higher and the rhythm 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, so that the first connecting members 320 occupy a smaller position 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 by means of concave-convex matching. 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 side wall of the first rotating rod 310 is concave inward, and the first connecting member 320 correspondingly forms a protrusion, and the concave and the protrusion cooperate to limit the mutual displacement between the first connecting member 320 and the first rotating rod 310.

[0050] In some embodiments, 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 can be understood that the first rotating rod 310 rotates relative to the fixed frame 100, that is, the first rotating rod 310 does not change in the vertical or horizontal direction, while the driving member 410 reciprocates in the horizontal direction, that is, the driving member 410 changes in the horizontal direction, and the relative position of the driving member 410 and the first rotating rod 310 changes in the horizontal direction. By using the first elastic connecting member 340 with elasticity to connect the driving member 410 and the first rotating rod 310, the first elastic connecting member 340 adapts to the position change between the two through its own elastic change. The horizontal plane where one 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, so that the heights of the two ends of the first elastic connecting member 340 are different. 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 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 movement tendency in the vertical direction, so that the first rotating rod 310 can realize rotation around itself under the pulling of the first elastic connecting member 340. The first elastic connecting member 340 can play a certain buffering role when the positions between the driving member 410 and the first rotating rod 310 change 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 circumferential direction. 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 meshingly connected to convert the horizontal movement output by the driving member 410 into the rotational movement of the first rotating rod 310.

[0053] In some embodiments, the first elastic connecting member 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 projection of the first rotating rod 310 of the first connecting mechanism 300a in the vertical direction. 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 and the elastic sheet 341. The elastic sheet 341 is connected to the driving member 410 and the first rotating rod 310 of the first connecting mechanism 300a respectively through the first fixing member 342 and the second fixing member 343, so that the elastic member has a more stable structure during the operation of the rhythmic furniture.

[0054] In some embodiments, the end of the elastic sheet 341 connected to the first rotating rod 310 of the first connecting mechanism 300a is located above or below it, and the specific details are not 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 recessed portion, and the protrusion cooperates with the recessed portion. The connection method between the first fixing member 342 and the first rotating rod 310 includes a recessed-protrusion connection, where the circumferential side wall of the first rotating rod 310 is recessed inwardly at the connection between the first rotating rod 310 and the first fixing member 342, and the corresponding first fixing member 342 protrudes outwardly, and the recesses and protrusions of the two cooperate to fix the first rotating rod 310 and the first fixing member 342, so that the connection relationship between the first fixing member 342 and the first rotating rod 310 of the first connecting mechanism 300a is more secure, and during the operation of the rhythmic furniture, the occurrence of looseness, sliding, etc. is reduced.

[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 method between the first fixing member 342 and the first rotating rod 310 of the first connecting mechanism 300a can also adopt a gear tooth meshing method. 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 meshed 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 connection mechanism 300a and the second connection mechanism 300b both further include a second rotating rod 350 and two second connecting members 330. The second rotating rod 350 is disposed through the two first connecting members 320. The second rotating rod 350 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, so as to realize the rotatable connection between the first connecting member 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 connection mechanism 300a and the second connection mechanism 300b, so that the rhythm furniture has better stability in the high-frequency up and down reciprocating motion.

[0059] In some embodiments, 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 a bearing 360. The connection via the bearing 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 when the corresponding parts rotate is reduced, and the user's pleasant experience is improved.

[0061] In some embodiments, please combine Figure 1 and Figure 6 As shown, the rhythmic furniture also includes a linkage mechanism 500, which is respectively connected to the first rotating rod 310 of the first connecting mechanism 300a and the first rotating rod of the second connecting mechanism 300b, so that when the first rotating rod 310 of the first connecting mechanism 300a rotates, the first rotating rod of the second connecting mechanism 300b is driven to rotate. The rotational motion of the first rotating rod 310 of the first connecting mechanism 300a is transmitted to the first rotating rod of the second connecting mechanism 300b through the linkage mechanism 500, so that the overall up and down motion of the rhythm frame 200 is consistent. At the same time, the linkage mechanism 500 transmits the force while transmitting the rotational motion, so that the rhythm frame 200 has a larger load.

[0062] In some embodiments, the linkage mechanism 500 includes a linkage member 510, a second elastic connector 520, and a third elastic connector 530. One end of the linkage member 510 is fixedly connected to the first rotating rod 310 of the first connecting mechanism 300a through the second elastic connector 520, and the other end of the linkage member 510 is fixedly connected to the first rotating rod of the second connecting mechanism 300b through the third elastic connector 530. By providing the second elastic connector 520 and the third elastic connector 530, the user can feel less frustration when the rhythmic furniture changes direction up and down, thereby improving the user's use experience.

[0063] In some embodiments, the linkage mechanism 500 includes a chain connected at the head and tail ends and two annular gears, the two annular gears are 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 meshed 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, and then drives 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, please refer to Figure 6 The driving member 410 and the connecting member 510 are sheet structures. On the one hand, the sheet 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 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, Figure 8As shown, the rhythmic furniture also includes a linkage mechanism 500, which includes a linkage member 510. The linkage member 510 connects the driving mechanism 400 and the first rotating rod of the second connecting mechanism 300b respectively. The driving mechanism 400 is used to make the linkage member 510 output at least a reciprocating motion in the horizontal direction, so as to convert the horizontal motion output by the driving mechanism 400 into a rotational motion of the first rotating rod of the second connecting mechanism 300b. By connecting the driving mechanism 400 with the linkage member 510, 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 is more synchronized, thereby making the motion of each part of the rhythm frame 200 more synchronized. 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 driving mechanism 400 includes a motor and a conversion mechanism, the motor outputs a rotational motion, the conversion mechanism converts the rotational motion output by the motor into at least a reciprocating motion in the horizontal direction, and the conversion mechanism is in transmission connection with the driving member 410 to transmit the converted reciprocating motion in the horizontal direction to the first rotating rod 310 of the first connecting mechanism 300a. It can be understood that the conversion mechanism that converts the rotational motion output by the motor into at least a reciprocating motion in the horizontal direction is common, such as a gear rack mechanism, a crank slider mechanism, a swing 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 occupancy of the driving member 410 and the conversion mechanism in the height direction, 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.
