Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a multi-directional rhythmic motor core and rhythmic furniture. Background Technology

[0002] In modern home life, innovative furniture products such as rhythmic chairs and rhythmic beds have quickly won the favor of consumers with their unique massage experience. These products use a carefully designed rhythmic core, whose structure consists of two frames: a fixed frame and a movable frame. Through the drive mechanism on the fixed frame, the movable frame can reciprocate rhythmically in the horizontal direction, bringing a comfortable massage sensation to the user.

[0003] To achieve reciprocating motion in a direction other than horizontal, an additional frame and drive mechanism need to be added to the movable frame. This additional drive mechanism is responsible for driving the new frame to reciprocate up and down. However, during horizontal reciprocating motion, the additional drive mechanism needs to follow the movement of the movable frame. This causes the drive mechanism to be affected by the horizontal motion, resulting in vibration and loosening of internal components, which in turn affects its service life, reduces transmission stability, and degrades the user experience. Utility Model Content

[0004] This invention provides a multi-directional rhythmic motor core to solve the problem in related technologies where, during the bidirectional motion process of a rhythmic motor core, the internal components of its related drive mechanism vibrate and loosen, thus affecting its service life, resulting in low transmission stability and reduced user experience.

[0009] The fixed frame is provided with a first drive mechanism and a second drive mechanism, and the power output ends of both the first drive mechanism and the second drive mechanism are connected to the telescopic mechanism for transmission.

[0010] The first driving mechanism drives the telescopic mechanism to slide horizontally, so that the movable frame reciprocates horizontally relative to the fixed frame; the second driving mechanism drives the telescopic mechanism to extend and retract, so that the movable frame reciprocates vertically relative to the fixed frame.

[0011] The first drive mechanism and the second drive mechanism can operate synchronously or independently.

[0012] According to the present invention, at least one of the first driving mechanism and the second driving mechanism is configured as an eccentric driving mechanism.

[0017] A drive shaft is connected to the telescopic mechanism, and the other end of the drive rocker arm is connected to the drive shaft.

[0018] The rotation center of the portion of the transmission rocker arm that mates with the first eccentric shaft is eccentrically positioned to be opposite to the rotation center of the portion of the first drive motor that mates with the first eccentric shaft.

[0026] According to the present invention, a multi-directional rhythmic motor core is provided, wherein the first driving mechanism and the second driving mechanism are spaced apart on the fixed frame.

[0027] According to the present invention, a multi-directional rhythmic actuator is provided, wherein the telescopic mechanism is a scissor arm mechanism.

[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0045] The following is combined Figures 1-4This invention describes a multi-directional rhythmic motion core and rhythmic furniture. The rhythmic furniture includes the aforementioned rhythmic motion core and a supporting body mounted on the rhythmic motion core. It is understood that, in embodiments of this invention, the rhythmic furniture may be a rhythmic chair, a rhythmic bed, etc.

[0046] Reference Figures 1 to 4 This utility model provides a multi-directional rhythmic motor core, including a fixed frame 100, a movable frame 200, and a telescopic mechanism 300. The movable frame 200 is movably disposed above the fixed frame 100. The telescopic mechanism 300 is disposed between the fixed frame 100 and the movable frame 200. One end of the telescopic mechanism 300 is slidably connected to the fixed frame 100, and the other end is movably connected to the movable frame 200.

[0047] The fixed frame 100 is provided with a first drive mechanism 400 and a second drive mechanism 500. The power output ends of both the first drive mechanism 400 and the second drive mechanism 500 are connected to the telescopic mechanism 300 for transmission.

[0048] The first drive mechanism 400 drives the telescopic mechanism 300 to slide horizontally, so that the movable frame 200 reciprocates horizontally relative to the fixed frame 100. The second drive mechanism 500 drives the telescopic mechanism 300 to extend and retract, so that the movable frame 200 reciprocates vertically relative to the fixed frame 100.

[0049] The first drive mechanism 400 and the second drive mechanism 500 can operate synchronously or independently.

[0050] The multi-directional rhythmic motor core provided by this utility model integrates a first drive mechanism 400 and a second drive mechanism 500 on the fixed frame 100, avoiding the need to add an extra frame and drive mechanism on the movable frame 200. This reduces the complexity of the movable frame 200, reduces potential damage to the drive mechanism caused by the movement of the movable frame 200, simplifies the overall structure, and reduces maintenance difficulty and cost.

[0051] Different users may have different needs regarding massage intensity and method. This design better adapts to the needs of different users, providing a personalized massage experience with good adaptability. When running synchronously, users can experience a full-range rhythmic massage, while independent operation offers a more customized massage experience. When horizontal back-and-forth rhythmic motion is needed, the first drive mechanism 400 can work independently without affecting the operation of the second drive mechanism 500. Similarly, when vertical up-and-down rhythmic motion is needed, the second drive mechanism 500 can work independently, unaffected by horizontal rhythmic motion. This enhances the functionality, safety, and durability of the rhythmic core, providing users with richer and more personalized home massage solutions.

[0052] Specifically, refer to Figures 1 to 4 In this embodiment of the invention, both the first drive mechanism 400 and the second drive mechanism 500 are configured as eccentric drive mechanisms. Of course, the first drive mechanism 400 can also be a telescopic push rod mechanism, and the second drive mechanism 500 can be an eccentric drive mechanism; this is not a limitation.

[0053] With the above structure, the eccentric drive mechanism can provide a stable and uniform rhythm, reduce vibration and bumps, making the massage experience more comfortable and smooth, and helping to reduce noise during operation, creating a quieter user environment.

[0054] Specifically, refer to Figures 1 to 4 In this embodiment of the utility model, the first drive mechanism 400 includes a first drive motor 410, a first eccentric shaft 420, a transmission rocker arm 430, and a transmission shaft 440. The first drive motor 410 is mounted on the fixed frame 100, the first eccentric shaft 420 is rotatably mounted on the fixed frame 100, the output end of the first drive motor 410 is connected to the first eccentric shaft 420, one end of the transmission rocker arm 430 is connected to the first eccentric shaft 420, the transmission shaft 440 is connected to the telescopic mechanism 300, and the other end of the transmission rocker arm 430 is connected to the transmission shaft 440.

[0055] The rotation center of the part of the transmission rocker arm 430 that mates with the first eccentric shaft 420 is eccentrically set with the rotation center of the part of the first drive motor 410 that mates with the first eccentric shaft 420.

[0056] With the above structure, due to the design of the first eccentric shaft 420, the rotational motion generated by the first drive motor 410 is converted into eccentric motion, thereby generating a periodic torque on the transmission shaft 440. This torque is transmitted to the telescopic mechanism 300, causing the telescopic mechanism 300 to move and drive the movable frame 200 to reciprocate horizontally relative to the fixed frame 100. The structure is compact and provides flexible, efficient and precise motion control.

[0057] Specifically, in this embodiment of the utility model, the telescopic mechanism 300 is provided with a transmission plate 310, and the transmission plate 310 and the power output end of the second drive mechanism 500 are arranged to abut against each other vertically.

[0058] With the above structure, the transmission plate 310 abuts against the power output end of the second drive mechanism 500. Therefore, the transmission plate 310 directly contacts the power output end, reducing energy loss and improving power transmission efficiency. The top and bottom abutting design makes the overall structure more compact, saving space and making it suitable for use in space-constrained environments. It also facilitates inspection and maintenance. Because maintenance and repair are more convenient, the workload of professional technicians can be reduced, thereby lowering maintenance costs.

[0059] Specifically, in this embodiment, the transmission plate 310 is detachably connected to the telescopic mechanism 300. When the transmission plate 310 or the telescopic mechanism 300 experiences wear or damage, the detachable connection makes replacement or repair more convenient. Because maintenance and repair are easier, the workload of professional technicians can be reduced, thereby lowering maintenance costs.

[0060] It should be noted that in this embodiment, the transmission plate 310 and the telescopic mechanism 300 can be connected in the following ways: 1. Bolt and nut connection: corresponding threaded holes are provided on the transmission plate 310 and the telescopic mechanism 300, and they are fixed by bolts and nuts. The structure is stable, easy to disassemble, and can be reused. 2. Snap-on connection: snap-on and slots are provided on the transmission plate 310 and the telescopic mechanism 300. The two are tightly connected by pressing or sliding. Installation and disassembly are quick and tool-free, suitable for occasions with frequent disassembly. 3. Pin connection: holes are provided on the transmission plate 310 and the telescopic mechanism 300, and pins are fixed by passing through the holes. The connection is simple, disassembly is convenient, and it is suitable for small or light mechanisms.

[0061] Specifically, refer to Figures 1 to 4 In this embodiment of the utility model, the second drive mechanism 500 includes a second drive motor 510, a second eccentric shaft 520 and a drive wheel 530. The second drive motor 510 is mounted on the fixed frame 100, the second eccentric shaft 520 is rotatably mounted on the fixed frame 100, the output end of the second drive motor 510 is connected to the second eccentric shaft 520 for transmission, the drive wheel 530 is fixedly connected to the second eccentric shaft 520, and the drive wheel 530 abuts against the transmission plate 310.

[0062] The rotation center of the part of the structure where the drive wheel 530 and the second eccentric shaft 520 are engaged is eccentrically set with the rotation center of the part of the structure where the output end of the second drive motor 510 and the second eccentric shaft 520 are engaged.

[0063] It should be noted that the output end of the second drive motor 510 is connected to the second eccentric shaft 520 via a pulley structure 511. Of course, in some embodiments, it can also be connected via a gear structure.

[0064] With the above structure, due to the design of the second eccentric shaft 520, the rotational motion generated by the second drive motor 510 is converted into eccentric motion, thereby generating a periodic torque on the transmission shaft 440. This torque is transmitted to the telescopic mechanism 300, causing the telescopic mechanism 300 to move, and driving the movable frame 200 to move up and down relative to the fixed frame 100. The structure is compact and provides flexible, efficient and precise motion control.

[0065] It should be noted that in this embodiment, the width of the transmission plate 310 is adapted to the drive wheel 530. The width of the transmission plate 310 is greater than the width of the drive wheel 530, or the width of the transmission plate 310 is less than the width of the drive wheel 530, or the width of the transmission plate 310 is equal to the width of the drive wheel 530. This ensures that when the movable frame 200 moves horizontally, the transmission plate 310 is always in transmission cooperation with the drive wheel 530.

[0066] Of course, in this embodiment, the power output ends of the first drive mechanism 400 and the second drive mechanism 500 can also be coupled with the telescopic mechanism 300 in a Reuleaux triangle manner, which is not limited here.

[0067] Specifically, refer to Figures 1 to 4 In this embodiment of the invention, the first driving mechanism 400 and the second driving mechanism 500 are spaced apart on the fixed frame 100. By distributing the first driving mechanism 400 and the second driving mechanism 500 on the fixed frame 100, the load can be more evenly distributed on the fixed frame 100, reducing stress concentration at single points. The first driving mechanism 400 and the second driving mechanism 500 can work collaboratively, adjusting their respective working states as needed to optimize overall work efficiency.

[0068] Understandably, referring to Figures 1 to 4 In this embodiment of the invention, the telescopic mechanism 300 is a scissor arm mechanism. Due to its structural characteristics, the scissor arm mechanism can provide a very stable support platform and is suitable for occasions requiring smooth lifting and lowering.

[0069] Specifically, refer to Figures 1 to 4 In this embodiment, the scissor arm mechanism includes: at least one set of scissor arm assemblies 320, wherein the scissor arm assembly 320 includes a first scissor arm 321 and a second scissor arm 322 pivotally connected in the middle;

[0070] The upper end of the first scissor arm 321 is slidably connected to the movable frame 200, the lower end of the first scissor arm 321 is slidably connected to the movable frame 200, the upper end of the second scissor arm 322 is rotatably connected to the movable frame 200, and the lower end of the first scissor arm 321 is slidably connected to the fixed frame 100.

[0071] The first drive mechanism 400 is connected to the first scissor arm 321, and the second drive mechanism 500 is connected to the second scissor arm 322.

[0072] This can be understood as referring to Figures 1 to 4The first scissor arm 321 is provided with a linkage plate 330, which is connected to the transmission shaft 440 of the first drive mechanism 400; the second scissor arm 322 is provided with a transmission plate 310, which is engaged with the drive component of the second drive mechanism 500.

[0073] In this embodiment, it can be understood that the limit position of the horizontal rhythmic movement of the movable frame 200 is coordinated with the width of the transmission plate 310, so that the transmission plate 310 never disengages from the driving component when the movable frame 200 moves horizontally.

[0074] In this embodiment of the present invention, the scissor arm assembly 320 is configured as two sets, and the two sets of scissor arm assemblies 320 are spaced apart on opposite sides between the fixed frame 100 and the movable frame 200.

[0075] With the above configuration, the two sets of scissor arm assemblies 320 are distributed on opposite sides, which can provide a more stable support structure, reduce the possibility of tilting and swaying, and thus improve the overall stability of the structure.

[0076] Of course, in other embodiments, the scissor arm assembly 320 may also be configured as one set, three sets, etc., which is not limited here.

[0077] Of course, in some embodiments, the above-mentioned telescopic mechanism 300 may also include a first telescopic tube and a second telescopic tube that are nested together and slide up and down. The first telescopic tube is slidably connected to the fixed frame 100 in the left and right directions, and the second telescopic tube is connected to the movable frame 200. The first telescopic tube is connected to a linkage plate 330, and the second telescopic tube is connected to a transmission plate 310. Similarly, the movable frame 200 can be driven to reciprocate horizontally through the linkage plate 330 and the first drive mechanism 400, and the movable frame 200 can be driven to reciprocate up and down through the transmission plate 310 and the second drive mechanism 500. This is not limited here.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
