Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rocking chair technology, and specifically relates to a rocking chair. Background Technology
[0002] Currently, there are many types of rocking chairs on the market, but most of them use a fixed rocking mode, such as parallel movement, swinging, or rotation, which is monotonous. For example, Chinese patent CN115245261A discloses a translational swinging device and an electric rocking chair, which uses a base, a swing seat for mounting the cradle, a guide device for the swing seat to slide back and forth, and a drive device. It uses a drive device to drive the swing seat to slide horizontally back and forth with the cradle to realize the automatic rocking of the rocking chair. However, it can only slide horizontally back and forth and cannot rotate forward and backward. The mode is monotonous, the movement trajectory is not rich enough, and it is easy to become bored.
[0003] Some rocking chairs employ multi-dimensional composite rocking with various movements. For example, Chinese patent CN220800614U discloses a rocking chair that can rock back and forth and up and down. A sliding seat is mounted on a base that can move back and forth. The base has a first drive mechanism that is connected to the sliding seat and drives its back-and-forth movement. The seat body is mounted on the sliding seat via a second drive mechanism that drives the seat body to rock up and down. This combines horizontal back-and-forth rocking with up-and-down rocking. Because it uses two sets of drives, its cost is high and its structure is complex, making it inconvenient for production, sales, and technology promotion.
[0004] There are also rocking chairs with separate controls, such as Chinese patent CN117017010A. When electric rocking is required, the base frame is fixed relative to the support surface by the drive unit, and the seat support frame can be driven to rock by the electric unit. When manual rocking is required, the drive unit is operated to return to its original position, so that the base frame is movably supported on the support surface, and the base frame can rock relative to the support surface, and the seat support frame can be driven to rock manually. However, it can only achieve two independent movement modes, cannot link movements, the movement trajectory is not rich enough, and the back-and-forth rocking movement mode can only be operated manually, which is inconvenient to use. Utility Model Content
[0005] The purpose of this utility model is to disclose a rocking chair that can realize a linkage mode combining displacement and rocking, with rich motion trajectories, convenient use, and low cost.
[0006] To achieve the above objectives, this utility model discloses a rocking chair, comprising:
[0007] A rocking support that can reciprocate along a first direction, with the bottom of the rocking support set in an arc shape that is low in the middle and high at both ends;
[0008] The electric component is mounted on the rocker support;
[0009] A seat for carrying a user is connected to an electric motor, which drives the seat to move back and forth at least in a first direction.
[0010] When the electric motor drives the seat to move back and forth relative to the rocker support, the center of gravity of the seat changes back and forth at least along the first direction. At the same time, the balance point of the rocker support changes. Under the action of gravity, the rocker support, along with the electric motor and the seat, produces a rocking motion. While the rocker support is rocking, the electric motor continues to drive the seat to move back and forth, so that the seat simultaneously moves back and forth along the first direction and rocks.

[0017] As an optional implementation, one end of the first driving member is eccentrically pivoted to the first worm gear, and the other end of the first driving member is pivotally pivoted to the carrier member. When the displacement drive motor rotates, it drives the pivot point between the first driving member and the first worm gear to rotate around the axis of the first worm gear, thereby driving the carrier member to move back and forth with the seat.
[0018] As an optional implementation, the connecting mechanism includes a first driving member and a carrier member.

[0081] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0082] Example 1
[0083] Please see Figures 1 to 11 As shown in the figure, this application provides a rocking chair, including a rocking support 1, an electric motor 2, a seat 3, a housing 7, a damping assembly 4, and a first locking / unlocking assembly 5. The technology of this rocking chair can be applied to both infant rocking chairs and leisure rocking chairs.
[0084] The bottom of the rocker support 1 is designed as an arc shape with a low middle and high ends. The rocker support 1 can be placed on the ground or a support surface. According to the change of the balance fulcrum of the rocker support 1, the rocker support 1 can reciprocate along the first direction. The electric motor 2 is installed on the rocker support 1. The seat body 3 is used to support the user. The seat body 3 is connected to the electric motor 2. The electric motor 2 is used to drive the seat body 3 to move back and forth at least in the first direction. When the electric motor 2 drives the seat body 3 to move back and forth relative to the rocker support 1, the center of gravity of the seat body 3 changes back and forth at least in the first direction. At the same time, the balance fulcrum of the rocker support 1 changes. Then, under the action of gravity, the rocker support 1, along with the electric motor 2 and the seat body 3, produces a self-rocking motion. When the rocker support 1 is rocking, the electric motor 2 continues to drive the seat body 3 to move back and forth, so that the seat body 3 simultaneously produces a back and forth motion and a rocking motion along the first direction.
[0085] Specifically, in this example, the electric motor 2 can drive the seat 3 to swing in a circular or arc shape relative to the rocker support 1 in the vertical plane. That is, the seat 3 can move horizontally and vertically relative to the rocker support 1, satisfying the requirement that the electric motor 2 drives the seat 3 to move back and forth relative to the rocker support 1 in the first direction. This ensures that the change in the center of gravity of the seat 3 affects the balance point of the rocker support 1. Combined with... Figures 4 to 6 With the left side as the front end in the first direction and the right side as the rear end in the first direction, when the electric unit 2 drives the seat 3 to move to the left, the weight of the seat 3 shifts to the left, which will cause the rocking support 1 to rock to the left along with the electric unit 2 and the seat 3. When the electric unit 2 drives the seat 3 to move to the right, the weight of the seat 3 shifts to the right, which will cause the rocking support 1 to rock to the right along with the electric unit 2 and the seat 3.
[0086] The above scheme utilizes the change in the center of gravity of the seat 3 during its reciprocating movement to change the balance point of the rocker support 1, thereby driving the rocker support 1 to rock and achieve self-rocking action. In this way, only one electric motor 2 is needed to drive the seat 3 to simultaneously produce a linkage mode of reciprocating movement and rocking, resulting in rich motion trajectories, convenient use, and low cost.
[0087] See Figure 1 , Figures 4 to 6 The damping components 4 are four in number and divided into two groups. Two damping components 4 are connected to the front end of the rocker support 1, and the other two damping components 4 are connected to the rear end of the rocker support 1. When the rocker support 1 rocks, the damping components 4 cushion the rocking motion against the ground or support surface, making the rocking motion slow down and less likely to cause fright. This also makes the overall linkage and rocking motion of the seat 3 smoother. Specifically, in... Figure 4In the state shown, the damping component 4 at the front end is compressed and rotated to generate a buffer. Figure 6 In the state shown, the damping component 4 at the rear end is compressed and rotated to generate a buffer.
[0088] Of course, the number of damping components 4 can be changed according to actual design needs; for example, one, two, or three can be set. Based on the structure of the rocker support 1 in this embodiment, four damping components 4 are preferred.
[0089] As a preferred example, the rocker support 1 may specifically include two arc-shaped rockers 11, a crossbar 12, a connector 13, and a mounting box 18. The two arc-shaped rockers 11 are arranged at intervals, with the middle of the arc-shaped rockers 11 being lower and the two ends being higher, so that the bottom of the rocker support 1 satisfies the arc shape of being lower in the middle and higher at both ends. Several crossbars 12 are provided, and the crossbars 12 are fixed between the two arc-shaped rockers 11 to form a stable bottom support structure. The connector 13 is fixedly mounted on the crossbar 12, and the mounting box 18 is fixedly mounted on the connector 13. In this example, the electric motor 2 will be specifically installed in the mounting box 18 to realize the installation of the electric motor 2 on the rocker support 1. The outer shell 7 is connected to the connector 13 and covers the mounting box 18 and the electric motor 2 to hide and protect the electric motor 2. In addition, based on the application of damping components 4, each arc-shaped rocker arm 11 is provided with damping components 4 at both ends. The damping components 4 on the two arc-shaped rocker arms 11 are connected by an intermediate rod 45 so that the two damping components 4 located at the front or rear end at the same time can move synchronously.
[0090] See Figure 3 , Figures 7 to 9 As a preferred embodiment of the damping component 4 of this utility model, the damping component 4 includes a mounting base 41, a buffer arm 42, and a first elastic element 43. The mounting base 41 is connected to the end of the arc-shaped rocker arm 11 in the rocker support 1. The buffer arm 42 is pivotally connected to the mounting base 41 around the first rotating shaft 411. The first elastic element 43 is connected to the mounting base 41 and the buffer arm 42. When the rocker support 1 rocks, the buffer arm 42 is pushed by the ground or the support surface and rotates around the first rotating shaft 411, driving the first elastic element 43 to store energy and buffer. Preferably, the first elastic element 43 includes a torsion spring, which is sleeved on the first rotating shaft 411. One end of the torsion spring is connected to the mounting base 41, and the other end of the torsion spring is connected to the rotating sleeve 422 in the buffer arm 42.
[0091] Combination Figure 2Further preferably, the buffer arm 42 has a first position where it is flipped outwards and supported on the ground or support surface. When the buffer arm 42 is in the first position, it supports the rocking support 1 and lifts the rocking support 1 off the ground or support surface. In this state, the electric motor 2 drives the seat 3 to move back and forth, and the rocking support 1 does not rock, thus forming different rocking modes. In this way, the rocking chair has a linkage mode that combines displacement and rocking, as well as a single rocking mode where only the electric motor 2 drives the seat 3 to move. In addition, there is a fixed mode, in which the buffer arm 42 is in the first position and the electric motor 2 does not work, to meet the different needs of parents caring for infants and young children.
[0092] See Figure 8 and Figure 9 To prevent the buffer arm 42 from disengaging from the first position, a buckle 4214 is provided on the buffer arm 42, and a slot 412 is provided on the mounting base 41. When the buffer arm 42 is flipped to the first position, the buckle 4214 and the slot 412 engage to limit the buffer arm 42 to the first position. Of course, the buckle 4214 and the slot 412 can be interchanged, such as setting the buckle 4214 on the mounting base 41 and setting the slot 412 on the buffer arm 42. In order to controllably switch the rocking support 1 between the rocking state and the fixed state, a first locking and unlocking component 5 is provided on the buffer arm 42. The first locking and unlocking component 5 has the functions of limiting the buffer arm 42 to remain in the locked state driven by the first elastic member 43, and releasing the first elastic member 43 from the unlocked state of the buffer arm 42. When the first locking and unlocking component 5 is in the unlocked state, the buffer arm 42 is allowed to flip to the first position.
[0093] On the other hand, in order to reduce the friction of the damping component 4 when it plays a buffering role, and to improve the stability of the damping component 4 when it is supported on the ground, preferably, one end of the buffer arm 42 is provided with a second rotating unit 44. When the rocking support 1 rocks on its own, the second rotating unit 44 rolls against the ground or support surface to reduce the friction between the buffer arm 42 and the ground or support surface in the linkage swing mode. When the buffer arm 42 is flipped to the first position, the second rotating unit 44 is disengaged from the ground or support surface to prevent the rocking chair from sliding. In addition, when the rocking chair needs to be moved in this state, the rocking chair can be tilted so that the second rotating unit 44 at the front or rear end contacts the ground, thereby making it easier to push the rocking chair to the desired position.
[0094] As a specific example, the buffer arm 42 includes an arm body 421 and a rotating sleeve 422. The rotating sleeve 422 is pivotally connected to the first rotating shaft 411, and one end of the arm body 421 is pivotally connected to the rotating sleeve 422. Based on the aforementioned buckle 4214 and second rotating unit 44, the buckle 4214 is located at one end of the arm body 421, and the second rotating unit 44 is installed at the other end of the arm body 421. The first elastic element 43 includes a torsion spring, which is sleeved on the first rotating shaft 411. One end of the torsion spring is connected to the mounting base 41, and the other end of the torsion spring is connected to the rotating sleeve 422. The first locking and unlocking assembly 5 includes a first locking block 51 and a second elastic element 52. The arm body 421 is provided with a first cavity 4211, a second cavity 4212, and a through hole 421. 3. The through hole 4213 connects the first cavity 4211 and the second cavity 4212. The rotating sleeve 422 is located in the first cavity 4211. The first locking block 51 is movably disposed in the second cavity 4212. The second elastic element 52 is preferably a spring. One end of the second elastic element 52 is connected to the first locking block 51, and the other end of the second elastic element 52 is connected to the arm body 421. The first locking tongue 511 on the first locking block 51 can pass through the through hole 4213 to insert into the first locking groove 4221 on the rotating sleeve 422 to form a lock, so that the arm body 421 and the rotating sleeve 422 are relatively fixed. Alternatively, the first locking tongue 511 on the first locking block 51 can disengage from the first locking groove 4221 on the rotating sleeve 422 to form an unlock, so that the arm body 421 and the rotating sleeve 422 can rotate relative to each other.
[0095] The working principle of the damping component 4 in the above scheme is as follows:
[0096] When the damping component 4 is needed to support the rocker support 1, manually move the first locking block 51 to disengage the first locking tongue 511 on the first locking block 51 from the first locking groove 4221 on the rotating sleeve 422, thus unlocking the device. The second elastic element 52 is compressed. Then, manually rotate the arm body 421 downwards to misalign the through hole 4213 and the first locking groove 4221 until the buckle 4214 engages with the groove 412. At this time, the buffer arm 42 flips to the first position. When the rocker support 1... When it touches the ground, the rotating arm body 421 rotates back, causing the buckle 4214 to disengage from the slot 412 until the through hole 4213 and the first locking slot 4221 are aligned. At this time, under the elastic force of the second elastic member 52, the first locking tongue 511 passes through the through hole 4213 and inserts into the first locking slot 4221 to form a lock, so that the arm body 421 and the rotating sleeve 422 are relatively fixed, and the arm body 421 and the rotating sleeve 422 are simultaneously subjected to the elastic force of the first elastic member 43.
[0097] See Figure 10 and Figure 11To satisfy the driving function of the electric unit 2 on the seat 3 and to ensure that the displacement of the seat 3 is not affected by the tilt of the rocker support 1, the electric unit 2 includes a displacement drive motor 21, a first worm gear assembly 22, and a connecting mechanism 23. The displacement drive motor 21 and the first worm gear assembly 22 are both mounted on the rocker support 1, more specifically on the mounting box 18 in the rocker support 1. The first worm gear assembly 22 includes a first worm 221 and a first worm wheel 222. A first pulley 211 is provided on the output shaft of the displacement drive motor 21, and a second pulley 213 is provided on the rotating shaft of the first worm 221. The first transmission belt 212 is wound around... The first pulley 211 and the second pulley 213 are provided so that when the displacement drive motor 21 rotates, it can drive the first worm 221 to rotate, thereby realizing the transmission connection between the displacement drive motor 21 and the first worm 221. Of course, the transmission connection between the displacement drive motor 21 and the first worm 221 can also be other structures, such as gear sets or couplings. The first worm 221 meshes with the first worm wheel 222, the first worm wheel 222 is connected to the connecting mechanism 23, and the connecting mechanism 23 is connected to the base 3. When the displacement drive motor 21 rotates, the connecting mechanism 23 drives the base 3 to move back and forth. In this scheme, the displacement drive motor 21 serves as the sole power source for driving the seat 3 to both move and rock. The first worm gear assembly 22 serves as a tool to convert the high speed and low torque of the displacement drive motor 21 into a low speed and high torque output. It can also prevent the displacement drive motor 21 from reversing due to the reverse force applied by the load. This effectively ensures that the electric unit 2 continues to drive the seat 3 to move towards the reset position when the rocking support 1 is rocking. This overcomes the defect in the prior art (such as Chinese patent CN117017010A) that requires the use of the weight of the seat to generate the reset force, which causes the seat to be unable to swing or to swing unevenly when the rocking support is tilted.
[0098] In this embodiment, as a preferred embodiment of the connecting mechanism 23, two connecting mechanisms 23 are provided and arranged symmetrically. Using two connecting mechanisms 23 can more stably support the seat 3. The connecting mechanism 23 includes a first driving member 231, a bearing member 232, and a limiting component 24. One end of the first driving member 231 is connected to the first worm gear 222, and the other end of the first driving member 231 is pivotally connected to the bearing member 232. The pivot axis between the first driving member 231 and the bearing member 232, and the axis of the first worm gear 222 are all horizontally arranged and both intersect with the first direction. The bearing member 232 is connected to the seat 3 and supports the seat 3. When displacement... When the drive motor 21 rotates, it drives the carrier 232, along with the seat 3, to swing in a circular or arc shape relative to the rocking support 1 on the vertical plane. Specifically, the movement trajectory of the carrier 232 is circular or arc-shaped, including simultaneous lifting and horizontal movement. The horizontal movement will cause the carrier 232, along with the seat 3, to move back and forth in the first direction. The function of the limiting component 24 is to limit the movement trajectory of the carrier 232. The limiting component 24 is connected between the carrier 232 and the rocking support 1, which can prevent the carrier 232 from rotating and failing to complete the circular or arc swing when the first drive component 231 is pivotally connected to the carrier 232 on a single axis. The limiting component 24 preferably consists of two connecting rods 241, two second mating parts 242, and two second limiting parts 243. The two connecting rods 241 are arranged at intervals, with one end of each connecting rod 241 pivotally connected to the rocker support 1 and the other end pivotally connected to the bearing member 232. The distance between the pivot axis of the first driving member 231 and the bearing member 232 and the axis of the first worm gear 222 is L1, and the distance between the pivot axes of the two ends of the connecting rod 241 is L2, satisfying L1=L2. At this time, the cooperation between the connecting rod 241 and the first driving member 231 can limit the circumferential or arc trajectory of the bearing member 232. The application of the second mating parts 242 and the second limiting parts 243 is to further avoid or reduce the bearing member 232. 2. Shaking occurs, wherein the second limiting member 243 is disposed on the rocker support 1, and the second limiting member 243 is provided with an annular guide surface 2431. The second mating member 242 is pivotally connected to the bearing member 232 and is slidably disposed along the annular guide surface 2431. The annular guide surface 2431 is used to abut against the second mating member 242 to limit the shaking of the first driving member 231. Of course, the objects on which the second mating member 242 and the second limiting member 243 are disposed can also be interchanged. For example, the second limiting member 243 can be disposed on the bearing member 232, and the second mating member 242 can be pivotally connected to the rocker support 1. In addition, the number of connecting rod 241, second mating member 242 and second limiting member 243 can also be varied according to design needs.
[0099] In the above connection structure scheme, since the bearing member 232 and the seat 3 swing together relative to the rocking support 1 in a circular or arc shape on the vertical plane, no matter what the tilt angle of the rocking support 1 is, it cannot have a superimposed effect on the displacement movement of the seat 3, which can well ensure the smoothness of the seat 3's movement in both displacement and rocking.
[0100] In the above-described connection structure, the bearing member 232 carries the seat 3 together with the rocking support 1 in a circular or arc-shaped motion. A second mating member 242 and a second limiting member 243 are provided, fixing the second limiting member 243 relative to the rocking support 1. The second mating member 242 rotates relative to the bearing member 232 and slides relative to the annular guide surface 2431 of the second limiting member 243. The annular guide surface 2431 abuts against the second mating member 242, and the second limiting member 243 guides the sliding of the second mating member 242 through the annular guide surface 2431 and provides a relatively limiting effect. Thus, the combination of the second mating member 242 and the second limiting member 243 avoids or reduces the swaying of the bearing member 232. When the seat 3 moves or stops at a position biased to one side, no downward overturning force is generated, and the seat 3 is less prone to swaying. Furthermore, it avoids shaking during circular or arc-shaped motion, resulting in high stability, high balance, and a simple overall structure with low cost.
[0101] See Figure 10 In this embodiment, the electric motor 2 further includes a first auxiliary tension spring 26, which provides an auxiliary lifting force. One end of the first auxiliary tension spring 26 is connected to the support member 232, and the other end is connected to the rocker support 1. Thus, the first auxiliary tension spring 26 can provide an auxiliary lifting force when driving the support member 232 upward, saving effort and making it easier for the displacement drive motor 21 to drive the support member 232 upward.
[0102] Example 2
[0103] Please see Figures 12 to 15 As shown, this embodiment also provides a rocking chair. The only difference between this embodiment and Embodiment 1 is the connection mechanism 23. The connection mechanism 23 in this embodiment is used to limit the sliding movement trajectory of the seat 3 relative to the rocking support 1. It adopts a sliding support member 232. The two ends of the first driving member 231 are respectively connected to the first worm gear 222 and the support member 232. When the displacement drive motor 21 rotates, it drives the support member 232 to move the seat 3 back and forth.
[0104] Specifically, in this embodiment, the connecting mechanism 23 includes a first driving member 231 and a bearing member 232. The bearing member 232 is slidably mounted on the rocker support 1 along a first direction. Specifically, a guide rail 2322 is provided on each side of the bearing member 232. Multiple rollers 16 are provided on the connecting body 13 in the rocker support 1 corresponding to the guide rails 2322. The rollers 16 are paired and clamped on the upper and lower sides of the guide rails 2322, so that the bearing member 232 slides smoothly and with low friction. One end of the first driving member 231 is eccentrically fixed to the first worm gear 222, and the bearing member 232... A second mating groove 2321 is provided, the extension direction of which intersects the first direction (preferably, both are perpendicular). The other end of the first driving member 231 is slidably disposed in the second mating groove 2321. When the displacement drive motor 21 rotates, it drives the first driving member 231 to rotate around the axis of the first worm gear 222 and move relative to the second mating groove 2321, so as to convert the unidirectional rotation of the displacement drive motor 21 into the linear reciprocating movement of the bearing member 232, thereby driving the bearing member 232 to move back and forth along with the seat 3. The advantage of this embodiment is that it has a lower cost.
[0105] It should be noted that, apart from the aforementioned distinguishing features, the specific structure of other components, the technical problems they solve, and their technical effects can be found in Embodiment 1, and will not be repeated in this embodiment.
[0106] Example 3
[0107] Please see Figures 16 to 18 As shown, this application embodiment also provides a rocking chair. The only difference between this embodiment and embodiment 2 is the connection method of the first driving member 231. The connection mechanism 23 in this embodiment is also used to limit the sliding movement trajectory of the seat 3 relative to the rocking support 1, and both use a sliding bearing member 232.
[0108] In this embodiment, the difference is that one end of the first driving member 231 is eccentrically pivoted to the first worm gear 222, and the other end of the first driving member 231 is pivotally pivoted to the bearing member 232. When the displacement driving motor 21 rotates, it drives the pivot point of the first driving member 231 and the first worm gear 222 to rotate around the axis of the first worm gear 222, so as to convert the unidirectional rotation of the displacement driving motor 21 into the linear reciprocating movement of the bearing member 232, thereby driving the bearing member 232 to move back and forth with the seat 3.
[0109] The advantage of this embodiment is that it is low in cost and the first driving component 231 is not easy to get stuck, so that the linkage swing of the seat 3 is smooth.
[0110] It should be noted that, apart from the aforementioned distinguishing features, the specific structure of other components, the technical problems they solve, and their technical effects can be found in Embodiment 1 or 2, and will not be repeated in this embodiment.
[0111] Example 4
[0112] Please see Figures 19 to 21 As shown, this application also provides a rocking chair. The only difference between this embodiment and embodiments 1, 2, or 3 is the connecting mechanism 23. In this embodiment, the connecting mechanism 23 is used to limit the movement trajectory of the seat 3 relative to the rocking support 1 to produce a basically horizontal or slightly tilted swing.
[0113] In this embodiment, the connecting mechanism 23 includes a first driving member 231 and a bearing member 232. The bearing member 232 forms a swing arm structure. One end of the bearing member 232 is pivotally connected to the swing support 1, and the other end of the bearing member 232 is connected to the seat body 3. The swing support 1 supports the bearing member 232, and the bearing member 232 supports the seat body 3. One end of the first driving member 231 is eccentrically pivotally connected to the first worm gear 222, and the other end of the first driving member 231 is pivotally connected to the bearing member 232. When the displacement drive motor 21 rotates, it drives the seat body 3 to move back and forth through the bearing member 232. Specifically, one end of the bearing member 232 is fixedly connected to the second rotating shaft 2324, which is pivotally connected to the connecting body 13 in the rocker support 1. The other end of the first driving member 231 is pivotally connected to the lower middle part of the bearing member 232. When the displacement drive motor 21 rotates, it drives one end of the first driving member 231 to rotate around the axis of the first worm gear 222 through the first worm gear assembly 22. The other end of the first driving member 231 drives the bearing member 232 to swing back and forth. The seat 3 swings back and forth with the other end of the bearing member 232. Specifically, the movement trajectory of the other end of the bearing member 232 is basically horizontal or slightly inclined arc. Its back and forth swing will cause the bearing member 232 to move back and forth in the first direction along with the seat 3.
[0114] The electric unit 2 in this embodiment differs from the prior art (such as Chinese patent CN117017010A) in that, when the rocking support 1 is rocking, the electric unit 2 continues to drive the seat 3 to move back to the reset position, so that the seat 3 simultaneously moves back to the reset position and rocks along the first direction. Specifically, the required linkage rocking effect is achieved by the power conversion of the first worm gear group 22 and the function of preventing reverse rotation.
[0115] It should be noted that, apart from the aforementioned distinguishing features, the specific structure of other components, the technical problems they solve, and their technical effects can be found in Embodiment 1 or 2, and will not be repeated in this embodiment.
[0116] Example 5
[0117] Please see Figures 22 to 24As shown, this application also provides a rocking chair. The only difference between this embodiment and embodiment 4 is the addition of a seat limiting mechanism 25 and a mode conversion unit 10. The connecting mechanism 23 in this embodiment is also used to limit the movement trajectory of the seat 3 relative to the rocking support 1 to produce a basically horizontal or slightly tilted swing.
[0118] In this embodiment, one end of the support member 232 is fixedly connected to a second rotating shaft 2324, and the other end of the support member 232 is pivotally connected to a follower rotating shaft 2325. The seat 3 is connected to one end of the follower rotating shaft 2325 and also includes a seat limiting mechanism 25. The seat limiting mechanism 25 includes a third limiting member 251 and a third mating groove 252. The third mating groove 252 is installed on the rocker support 1, and the third limiting member 251 is fixedly connected to the other end of the follower rotating shaft 2325. The third limiting member 251 and the third mating groove 252 cooperate, and the third limiting member 251 can move relative to the third mating groove 252. That is, the third mating groove 252 and the third limiting member 251 are used to... The rotation amplitude of the follower shaft 2325 relative to the support member 232 is controlled. When the follower shaft 2325 swings with the support member 232, the third limiting member 251 also swings with the follower shaft 2325 and moves relative to the third mating groove 252. The third mating groove 252 drives the third limiting member 251, and the third limiting member 251 drives the follower shaft 2325 to rotate relative to the support member 232. Since the seat 3 is connected to the follower shaft 2325, the angle between the seat 3 and the support member 232 can be limited to a set angle, thereby controlling the orientation of the seat surface of the seat 3 when it swings with the support member 232. It can be understood that the orientation of the seat surface of the seat 3 can be constant or variable, but both are controllable. The seat limiting mechanism 25 plays a corrective role to controllably limit the angle between the seat 3 and the support member 232.
[0119] It should be noted that the specific fit between the third limiting member 251 and the third mating groove 252 is known, so it will not be described here. This application also does not limit the specific structure between the third limiting member 251 and the third mating groove 252.
[0120] In this embodiment, optionally, a mode conversion unit 10 is also included. The mode conversion unit 10 is installed on the rocker support 1 and is connected to the third mating groove 252. The third mating groove 252 is movably connected to the rocker support 1, and the mode conversion unit 10 can drive the third mating groove 252 to change position. In this way, the amplitude of the rotation of the follower shaft 2325 relative to the bearing member 232 can be changed, thereby changing the amplitude of the deflection of the seat body 3 relative to the rocker support 1, thereby increasing or decreasing the range of angle change of the seat surface of the seat body 3, so as to change the rocking amplitude during compound rocking.
[0121] The mode conversion unit 10 can be manual or electric. In this embodiment, the mode conversion unit 10 is preferably electric. In this way, the mode conversion unit 10 can not only change the orientation of the seat surface of the seat body 3, but also, as needed, the driving effect of the mode conversion unit 10 can be combined into the compound rocking. For example, the mode conversion unit 10 and the displacement drive motor 21 can drive the seat body 3 to move at the same time, thereby increasing the rocking mode of the rocking chair.
[0122] One possible structure of the mode conversion unit 10 is as follows: The mode conversion unit 10 includes a mode conversion motor 101, a second worm gear assembly 102, and a second drive member 103. The mode conversion motor 101 and the second worm gear assembly 102 are both mounted on the rocker support 1, more specifically, on the connecting body 13 in the rocker support 1. The second worm gear assembly 102 includes a second worm 1021 and a second worm gear 1022. A third pulley 1011 is provided on the output shaft of the mode conversion motor 101, and a fourth pulley 1013 is provided on the rotating shaft of the second worm 1021. A second transmission belt 1012 is wound around the third pulley 1011 and the fourth pulley 1013, so that the mode conversion motor 101... When rotating, it can drive the second worm 1021 to rotate, thereby realizing the transmission connection between the mode conversion motor 101 and the second worm 1021. Of course, the transmission connection between the mode conversion motor 101 and the second worm 1021 can also be other structures, such as gear sets or couplings. The second worm 1021 and the second worm wheel 1022 mesh. One end of the second driving member 103 is eccentrically pivoted to the second worm wheel 1022, and the other end of the second driving member 103 is eccentrically pivoted to the third mating groove 252. The third mating groove 252 is pivotally connected to the rocker support 1. When the mode conversion motor 101 rotates, the second driving member 103 drives the third mating groove 252 to rotate and change its position. In this way, a high transmission ratio can be achieved, and self-locking can be achieved using a worm gear, which can prevent the reaction force from being transmitted back to the mode conversion motor 101 and causing impact on the mode conversion motor 101. Overall, the performance requirements of the mode conversion motor 101 are reduced, the service life of the mode conversion motor 101 is extended, and costs are saved. When the mode conversion motor 101 starts, it drives the third mating groove 252 to swing, thereby changing the position of the third mating groove 252 and thus changing the orientation of the seat surface of the base 3. When the mode conversion motor 101 stops operating, the third mating groove 252 can be fixed in a preset position.
[0123] It should be noted that, apart from the aforementioned distinguishing features, the specific structure of other components, the technical problems they solve, and their technical effects can be found in Embodiment 1 or 4, and will not be repeated in this embodiment.
[0124] Example 6
[0125] Please see Figures 25 to 32As shown, this application embodiment also provides a rocking chair. The difference between this embodiment and embodiments 1-5 is that the refined structure of the rocking support 1 is different, and it also includes a bottom support 6.
[0126] In this embodiment, the bottom support 6 supports the rocker support 1. The rocker support 1 rocks on the bottom support 6 according to the change of its balance point. The outer shell 7 is connected to the bottom support 6 and covers the rocker support 1 and the electric motor 2. In this way, the rocker support 1 is supported by the bottom support 6 in contact with the ground, so that the rocker support 1 does not have to touch the ground. This makes the reciprocating rocking of the rocker support 1 unaffected by uneven ground, and also facilitates the miniaturization of the rocker support 1. The outer shell 7 also covers the rocker support 1, making the overall shape more compact and aesthetically pleasing.
[0127] See Figure 30 In this embodiment, the arc-shaped bottom surface 17 of the rocker support 1 contacts the bottom support 6. To prevent the rocker support 1 from shifting or tipping in other directions, the rocker support 1 is provided with a first mating part 61 extending along a first direction, and the bottom support 6 is provided with a second mating part 14 extending along the first direction. The first mating part 61 and the second mating part 14 are engaged. The number of the first mating part 61 and the second mating part 14 is determined according to design requirements. The engagement of the first mating part 61 and the second mating part 14 is used to limit the movement of the rocker support 1 relative to the bottom support 6 in a second direction, wherein the first direction is perpendicular to the second direction. In addition, two baffles 63 can be provided on the bottom support 6. The two baffles 63 clamp the two sides of the rocker support 1 along the second direction, which can also serve to limit the rocker support 1. The above solution can improve the stability of the rocker support 1 when rocking on the bottom support 6.
[0128] In addition, to prevent the rocker support 1 from sliding along the first direction and tilting back and forth, a rocking angle limiting mechanism 9 is also included. The rocking angle limiting mechanism 9 includes a first limiting member 91 and a first mating member 92. The first limiting member 91 is disposed on the rocker support 1, and the first mating member 92 is disposed on the bottom support 6. When the rocker support 1 rocks, the first limiting member 91 slides relative to the first mating member 92, and the rocking angle limiting mechanism 9 limits the rocking angle range of the rocker support 1. This rocking angle limiting mechanism 9 guides and limits the stroke of the reciprocating rocking of the rocker support 1. Specifically, the first limiting member 91 includes a pin 911, and the first mating member 92 includes a first mating groove 921. When the rocker support 1 rocks, the pin 911 slides in the first mating groove 921. In order to reduce the friction of the pin 911 sliding in the first mating groove 921, a first rotating unit 912 is rotatably disposed on the pin 911. The first rotating unit 912 rolls with the groove wall of the first mating groove 921. It is understandable that the pin 911 and the first mating groove 921 can be interchanged, for example, the first mating groove 921 can be set on the rocker support 1, while the pin 911 can be set on the bottom support 6.
[0129] See Figures 27 to 30 In this embodiment, the buffering mechanism is achieved through second auxiliary tension springs 62. Several second auxiliary tension springs 62 can be provided, with one end connected to the rocker support 1 and the other end connected to the bottom support 6. Preferably, four second auxiliary tension springs 62 are provided, divided into two groups: two connected to the front end of the rocker support 1 and the other two connected to the rear end. When the rocker support 1 rocks, the second auxiliary tension springs 62 are stretched, generating a counter-force, slowing down the rocking motion, reducing the risk of startling the user, and making the overall linkage and rocking motion of the seat 3 smoother. Of course, the number of second auxiliary tension springs 62 can be changed according to actual design needs; for example, one, two, or three can be used. Based on the structure of the rocker support 1 in this embodiment, four second auxiliary tension springs 62 are preferred.
[0130] Combination Figures 27 to 29 With the left side as the front end in the first direction and the right side as the rear end in the first direction, when the electric motor 2 drives the seat 3 to move to the left, the gravity of the seat 3 shifts to the left, causing the rocking support 1 to rock to the left along with the electric motor 2 and the seat 3. The angle of the rocking motion is limited by the rocking angle limiting mechanism 9, and... Figure 28In the indicated state, the second auxiliary tension spring 62 at the rear end is stretched to provide cushioning; and when the electric motor 2 drives the seat 3 to move to the right, the weight of the seat 3 shifts to the right, causing the rocking support 1 to rock to the right along with the electric motor 2 and the seat 3. The angle of this rocking motion is also limited by the rocking angle limiting mechanism 9, and... Figure 29 In the state shown, the second auxiliary tension spring 62 located at the front end is stretched to generate a buffer.
[0131] Combination Figures 30 to 32 In this embodiment, to control the self-rocking action of the rocking support 1, a second locking and unlocking component 8 is also included. The second locking and unlocking component 8 is disposed on the bottom support 6. The second locking and unlocking component 8 has a locked state for limiting the rocking support 1 to remain relatively fixed to the bottom support 6, and an unlocked state for releasing the movement restriction of the rocking support 1. That is, when the second locking and unlocking component 8 is in the locked state, the electric unit 2 drives the seat body 3 to move back and forth, and the rocking support 1 cannot rock, thus forming different rocking modes; while when the second locking and unlocking component 8 is in the unlocked state, the rocking support 1 is allowed to rock itself, and the electric unit 2 drives the seat body 3 to move back and forth and rock simultaneously. Thus, the rocking chair has a linkage mode that combines displacement movement and rocking, and a single rocking mode in which only the electric unit 2 drives the seat body 3 to move; in addition, there is a fixed mode, in which the second locking and unlocking component 8 is in the locked state and the electric unit 2 does not work, to meet the different needs of parents caring for infants and young children.
[0132] As a preferred embodiment of the second locking / unlocking component 8: the second locking / unlocking component 8 includes a toggle member 81, a linkage member 82, a second locking block 83, and a third elastic member 84. The linkage member 82 and the second locking block 83 are respectively slidably mounted on the bottom support base 6, and the sliding direction of the linkage member 82 intersects the sliding direction of the second locking block 83. The linkage member 82 is provided with a drive groove 821, and the second locking block 83 is provided with a drive post 832. The drive groove 821 and the drive post 832 cooperate to convert the sliding of the linkage member 82 into the sliding of the second locking block 83. Of course, the positions of the drive groove 821 and the drive post 832 can also be interchanged. For example, the drive groove 821 is set in the second lock block 83, and the drive column 832 is set in the linkage member 82; one end of the third elastic member 84 is connected to the second lock block 83, and the other end of the third elastic member 84 is connected to the bottom support 6; the actuating member 81 is located on the outside of the housing 7, and a part of the actuating member 81 passes through the through hole 4213 of the housing 7 and is fixed to the linkage member 82. When the actuating member 81 is actuated, the second locking tongue 831 on the second lock block 83 is driven to insert into the second locking groove 15 on the swing support 1 to form a lock or the second locking tongue 831 on the second lock block 83 is driven to disengage from the second locking groove 15 on the swing support 1 to form an unlock. Specifically, when the actuating element 81 is pushed upward, the linkage element 82 slides upward, and the linkage element 82 drives the second locking block 83 to slide away from the rocker support 1. The second locking block 83 compresses the third elastic element 84, causing the second locking tongue 831 to disengage from the second locking groove 15. At this time, it is in the unlocked state, allowing the rocker support 1 to rock itself. When the actuating element 81 is pushed downward, the linkage element 82 slides downward, and the second locking block 83 is reset under the elastic force of the third elastic element 84 and slides towards the rocker support 1, causing the second locking tongue 831 to insert into the second locking groove 15. At this time, it is in the locked state, and the rocker support 1 cannot rock itself.
[0133] Of course, the second locking and unlocking component 8 can also adopt any other known specific structure to achieve locking and unlocking of the rocker support 1.
[0134] It should be noted that, apart from the aforementioned distinguishing features, the specific structure of other components, the technical problems they solve, and their technical effects can be found in Embodiment 1, and will not be repeated in this embodiment.
[0135] It should be noted that this embodiment does not involve any difference in the electric motor 2. Therefore, any solution of the electric motor 2 in embodiments 2-5 can be applied to this embodiment to replace the electric motor 2 of this embodiment and combine to form a new implementation scheme.
[0136] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
