[0047] In the following description, a large number of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only relates to preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0048] As described above, the existing electric cradles have a single form of movement, either translational movement or axial movement, which cannot fully simulate the movement trajectory of parents holding their babies with both hands. There are better baby cradle brands in the foreign market that can fully simulate parents' holding, but they still have disadvantages such as high prices, short service life, and low load capacity. In view of this, the present application provides a control device for a baby cradle and a baby cradle. The control device has a simple overall structure and low cost, and can control the moving platform to move in different directions, so that the moving platform can simulate different movement trajectories, which helps to better meet the user's usage needs. The specific structure of the control device and the baby cradle is described in detail below.

[0049] According to one aspect of the embodiments of the present application, a control device for a baby cradle is provided, wherein the baby cradle comprises a cradle body. Figure 1-4The control device includes: a moving platform 10, which is used to connect the cradle body; a base 40, which is arranged below the moving platform 10; and a driving component arranged between the moving platform 10 and the base 40. The number of the driving components is two groups, and the two groups of driving components are arranged at the bottom of the moving platform 10.

[0050] like Figure 5 As shown, the driving assembly includes a power assembly, an active arm 70, a driven arm 90 and a support arm 80; the first end of the active arm 70 is transmission-connected to the power assembly so as to rotate driven by the power assembly, the second end of the active arm 70 is hinged to the first end of the driven arm 90, and the second end of the driven arm 90 is hinged to the moving platform 10; the first end of the support arm 80 is connected to the driven arm 90, and the second end of the support arm 80 is hinged to the moving platform 10.

[0051] In this article, "connection" can be a direct connection or an indirect connection. Take the connection between the first end of the support arm 80 and the driven arm 90 as an example. Figure 5 In the illustrated embodiment, the first end of the support arm 80 is directly connected to the driven arm 90. However, in other embodiments not shown, the first end of the support arm 80 may also be indirectly connected to the driven arm 90. For example, a fixing block may be connected to the driven arm 90, and the first end of the support arm 80 may be fixedly connected to the fixing block, thereby, the first end of the support arm 80 may be indirectly connected to the driven arm 90 through the fixing block.

[0052] Similarly, in this article, "articulation" can be direct articulation or indirect articulation. Take the second end of the slave arm 90 being articulated with the moving platform 10 as an example for explanation. In some embodiments, the second end of the slave arm 90 can be directly articulated on the moving platform 10. In other embodiments, a connecting piece can be provided under the moving platform 10, and the second end of the slave arm 90 can be articulated with the moving platform 10 via the connecting piece. For example, the connecting piece can be as follows: Figure 5 The second end of the slave arm 90 can be hinged to the moving platform 10 via the fixing rod 110. The specific configuration of the fixing rod 110 is described in detail below and will not be repeated here. Figure 5 In some implementations, the second end of the driven arm 90 can be directly hinged to the connecting plate 120. In this case, the second end of the driven arm 90 can be indirectly hinged to the moving platform 10 via the connecting plate 120.

[0053] In this article, the specific way of "connection" includes but is not limited to any existing or future connection methods such as connection by screws, plugging, and clamping. The specific connection method can be selected according to actual needs, and this application does not limit this.

[0054] It is understood that "hinged" means that one component can rotate relative to another component. In some embodiments, a bearing seat can be provided between the two components to ensure smoother rotation between the two components. Figure 5 For example, in this embodiment, the second end of the active arm 70 is hinged to the first end of the driven arm 90. Specifically, the second end of the active arm 70 is hinged to the first end of the driven arm 90 through a light rod. A bearing seat is provided on the first end of the driven arm 90, and the light rod is fixedly connected to the inner ring of the bearing in the bearing seat. Of course, no bearing may be provided between the two components. In some embodiments, a through hole may be provided at the first end of the driven arm 90, the light rod may be inserted into the through hole, and the driven arm 90 may rotate relative to the light rod.

[0055] Optionally, the first end of the support arm 80 can be connected to any position on the driven arm 90. For example, the first end of the support arm 80 can be connected to the middle position of the driven arm 90, can be connected to a position close to the first end of the driven arm 90, can be connected to a position close to the second end of the driven arm 90, etc. Figure 5 In the illustrated embodiment, the first end of the support arm 80 is connected near the first end of the driven arm 90 .

[0056] In the solution of this example, the support arm 80 can move with the driven arm 90, that is, when the driven arm 90 moves, the relative position between the support arm 80 and the driven arm 90 remains unchanged. Compared with the method of connecting the moving platform 10 only through the driven arm 90, the support arm 80 can play an auxiliary supporting role for the moving platform 10, which helps to make the moving platform 10 more stable during operation and helps to improve the carrying capacity of the moving platform 10.

[0057] In the solution of this example, the driving component can drive the moving platform 10 to move. Specifically, the power component can drive the active arm 70 to rotate, and during the rotation of the active arm 70, it can drive the driven arm 90 hinged thereto to move. When the driven arm 90 moves, it can drive the moving platform 10 to move. By controlling the power components in the two groups of driving components to drive the corresponding active arms 70 to make the same or different (including different rotation speeds, different rotation directions, etc.) movements, the moving platform 10 can simulate different motion trajectories. In this way, the moving platform 10 can fully simulate the motion trajectory of parents holding their baby with both hands, and then the baby cradle installed on the moving platform 10 can fully simulate the parents' holding, which can better help the baby fall asleep.

[0058] In summary, the control device in this example has a simple overall structure, low cost, better operating stability and load-bearing capacity, and can simulate different motion trajectories, which helps to better meet the user's usage needs.

[0059] For example, Figure 5As shown, the support arm 80 is tilted in a direction away from the driven arm 90. In this case, a stable triangle can be formed between the support arm 80, the driven arm 90 and the moving platform 10. Thus, the supporting effect of the moving platform 10 can be further improved, and the stability and load-bearing capacity of the device during operation can be improved.

[0060] Optionally, the inclination angle of the support arm 80 can be set as needed. It can be understood that the inclination angle of the support arm 80 is the angle between the support arm 80 and the driven arm 90, and the vertex of the angle is the connection point between the support arm 80 and the driven arm 90. In some embodiments, the inclination angle can be in the range of [20°, 60°]. On the one hand, the inclination angle within the above range can make the support point of the driven arm 90 on the moving platform 10 (the support point can be the hinge point between the driven arm 90 and the moving platform 10) and the support point of the support arm 80 on the moving platform 10 (the support point can be the hinge point between the support arm 80 and the moving platform 10) spaced a certain distance apart, thereby helping to improve the structural strength and avoid deformation or instability of the moving platform 10 when bearing loads. On the other hand, the inclination angle within the above range can reduce the length of the support arm 80 while ensuring the structural strength, thereby helping to reduce the overall cost of the device.

[0061] According to the above technical solution, by tilting the support arm 80 in a direction away from the driven arm 90, a stable triangle can be formed between the support arm 80, the driven arm 90 and the moving platform 10, thereby helping to further improve the supporting effect on the moving platform 10 and improve the stability and load-bearing capacity of the device during operation.

[0062] For example, Figure 5 As shown, there are two slave arms 90 , which are arranged in parallel at the front and rear sides of the active arm 70 , and the two support arms 80 corresponding to the two slave arms 90 have different inclination angles.

[0063] For ease of understanding, in this article, Figure 2 The directions shown define the “front”, “rear”, “left”, “right”, “up” and “down” directions as the main viewing direction.

[0064] In the solution of this example, two slave arms 90 are arranged in parallel on the front and rear sides of the active arm 70. That is, the two slave arms 90 can be used together to drive the moving platform 10 to move, and this design method helps to improve the overall structural strength. Optionally, the distance between the two slave arms 90 can be within a preset distance range. The preset distance can be set according to actual needs. By making the distance between the two slave arms 90 within the preset distance range, it helps to make the two support points of the two slave arms 90 relative to the moving platform 10 separated by a certain distance, thereby helping to improve the structural strength and prevent the moving platform 10 from deforming or becoming unstable when bearing load.

[0065] In the solution of this example, the two support arms 80 corresponding to the two driven arms 90 have different inclination angles. Optionally, the inclination angles of the two support arms 80 on different sides of the two drive assemblies are the same, thereby improving the structural symmetry and making the overall structure more stable.

[0066] In summary, the technical solutions of the above examples help to further improve the overall structural strength and stability of the device.

[0067] exist Figure 5 In the illustrated embodiment, the two support arms 80 corresponding to the two driven arms 90 have different tilt angles. In other embodiments of the present application, the two support arms 80 corresponding to the two driven arms 90 may also have the same tilt angle.

[0068] Exemplarily, a fixing rod 110 is disposed at the bottom of the moving platform 10 , and the second end of the driven arm 90 and the second end of the supporting arm 80 are both hinged to the fixing rod 110 .

[0069] In such Figure 5 In the illustrated embodiment, a plurality of connecting plates 120 may be disposed at the bottom of the movable platform 10 , and the shape of the plurality of connecting plates 120 may be “L”-shaped or “U”-shaped. The fixing rod 110 may be passed through the plurality of connecting plates 120 .

[0070] exist Figure 5 In the illustrated embodiment, a bearing seat is disposed at the second end of the driven arm 90, and the fixing rod 110 is fixedly connected to the inner ring of the fixing seat at the second end of the driven arm 90. During operation of the device, the driven arm 90 and the support arm 80 can both rotate relative to the fixing rod 110.

[0071] In the above-mentioned technical solution, the second end of the driven arm 90 and the second end of the supporting arm 80 are both hinged on the fixing rod 110. Thus, the second end of the driven arm 90 and the second end of the supporting arm 80 can be connected together, and this arrangement helps to further strengthen the overall structural strength, thereby helping to further improve the stability and safety of the device operation.

[0072] For example, Figure 6 As shown, the base 40 includes a base bracket 402 and a static platform 403, and the static platform 403 is vertically arranged on the base bracket 402; two groups of power components corresponding to the two groups of driving components are respectively arranged on the front and rear sides of the static platform 403.

[0073] Optionally, the base support 402 may be a plate or a Figure 6 Bracket shown.

[0074] exist Figure 6 In the illustrated embodiment, the static platform 403 may be a plate vertically disposed on the base support 402. In other embodiments of the present application, the static platform 403 may also be a support.

[0075] exist Figure 6 In the embodiment shown, the static platform 403 can be fixedly mounted on the base bracket 402 by a plurality of L-shaped reinforcement plates. It can be understood that the arrangement of the static platform 403 of the present application is not limited to Figure 6 In the form of, for example, a mounting groove matching with the static platform 403 can be further provided on the base 40, and the static platform 403 can be inserted into the mounting groove.

[0076] Optionally, the power assembly can be installed entirely on the static platform 403, or entirely on the base support 402, or partially on the static platform 403 and partially on the base support 402. Figure 1-4 In the illustrated embodiment, all power components are installed on the static platform 403 , and the power output shaft of the power component penetrates the static platform 403 and is transmission-connected with the corresponding active arm 70 .

[0077] In the solution of this example, two groups of power components corresponding to the two groups of drive components are respectively arranged on the front and rear sides of the static platform 403. This arrangement can make full use of the space on both sides of the static platform 403, and compared with the arrangement of the two groups of power components on the same side, the arrangement of the two groups of power components on the front and rear sides of the static platform 403 occupies more concentrated space overall, thereby helping to optimize the overall volume and structure of the device and making the overall structure of the device more reasonable.

[0078] For example, Figure 1-4 , Figure 7As shown, the power assembly includes a motor 60 and a transmission assembly 50, and the transmission assembly 50 includes a housing 501, a transmission worm 503 and a transmission worm wheel 502. The transmission worm 503 and the transmission worm wheel 502 are both arranged inside the housing 501, and one end of the transmission worm 503 penetrates the housing 501 and is directly connected to the output shaft of the motor 60, and the transmission worm 503 is transmission-connected to the transmission worm wheel 502, and the transmission worm wheel 502 is transmission-connected to the first end of the active arm 70.

[0079] As described above, the power assembly can be installed entirely on the static platform 403, or entirely on the base support 402, or partially on the static platform 403 and partially on the base support 402. Figure 1-4 In the illustrated embodiment, the motor 60 and the transmission assembly are both mounted on the static platform 403. In other embodiments, the motor 60 and the transmission assembly may also be both mounted on the base bracket 402. In still other embodiments, one of the motor 60 and the transmission assembly may be mounted on the base bracket 402, and the other may be mounted on the static platform. For example, the motor 60 may be mounted on the base bracket, and the transmission assembly may be mounted on the static platform 403. For another example, the motor 60 may be mounted on the static platform 403, and the transmission assembly may be mounted on the base bracket 402.

[0080] Optionally, the type of the motor 60 can be selected according to actual needs. For example, the motor 60 can be a synchronous motor 60 .

[0081] In the solution of this example, the power of the motor 60 is transmitted to the active arm 70 by using the transmission worm 503 and the transmission worm wheel 502. This transmission method has better stability and can fully utilize the self-locking ability of the worm wheel 502 and the worm 503 structure to further improve the overall safety of the device.

[0082] In the solution of this example, the transmission worm 503 and the transmission worm wheel 502 are both arranged inside the housing 501. On the one hand, the housing 501 can protect the transmission worm 503 and the transmission worm wheel 502, and prevent external dust and the like from contaminating the transmission worm 503 and the transmission worm wheel 502. On the other hand, the housing 501 can also play a role of sound insulation to a certain extent, reducing the noise during the operation of the device, thereby helping to prevent the operating noise from affecting the sleeping effect of the baby cradle.

[0083] As described above, one end of the transmission worm 503 penetrates the housing 501 and is directly connected to the output shaft of the motor 60. That is, the output shaft of the motor 60 is directly connected to the transmission worm 503. On the one hand, this direct connection method helps to shorten the transmission distance, reduce power loss, and improve transmission efficiency. On the other hand, this method does not need to set other transmission components between the motor 60 and the transmission worm 503, and the structure is simple, which helps to reduce the overall cost of the device. On the other hand, this method can make the overall structure of the power assembly more compact, which helps to reduce the overall space occupied by the power assembly.

[0084] As described above, two groups of power components corresponding to the two groups of drive components are respectively arranged on the front and rear sides of the static platform 403. In some embodiments, the two motors 60 corresponding to the two groups of power components can be arranged in the same direction, for example, the two motors 60 can be arranged upward, downward, leftward, or rightward. In a preferred embodiment, the two motors 60 corresponding to the two groups of power components are arranged in opposite directions. Figure 1 In the embodiment shown, the two motors 60 are arranged in the left-right direction, and the arrangement directions of the two motors 60 are opposite. This arrangement helps to further improve the structural compactness of the power assembly.

[0085] In the above embodiment, the transmission worm 503 and the transmission worm wheel 502 are both arranged inside the housing 501, one end of the transmission worm 503 penetrates the housing 501 and is transmission-connected to the motor 60, the transmission worm 503 is transmission-connected to the transmission worm wheel 502, and the transmission worm wheel 502 is transmission-connected to the first end of the active arm 70. This arrangement helps to improve the transmission efficiency, and can make full use of the self-locking ability of the worm wheel 502 and the worm 503 structure, further improving the overall safety of the device.

[0086] For example, Figure 5 , Figure 8 As shown, the first end of the active arm 70 is connected to the sensing block 130, and the base 40 is provided with a first limit switch 150 and a second limit switch 160. When the active arm 70 rotates in a clockwise direction to a first limit position, the sensing block 130 triggers the first limit switch 150, and when the active arm 70 rotates in a counterclockwise direction to a second limit position, the sensing block 130 triggers the second limit switch 160.

[0087] The first limit position and the second limit position can be set according to the actual stroke of the device, which will not be described in detail.

[0088] In the solution of this example, when the limit switch (including the first limit switch 150 and the second limit switch 160) is triggered, the power assembly stops driving the active arm 70, and the active arm 70 stops rotating. In some implementation schemes, the limit switch can send a stop signal to the power assembly when it is triggered to stop the power assembly. In other implementation schemes, the control device can also include a controller. The limit switch can send a stop signal to the controller when it is triggered, and the controller can control the power assembly to stop running when it receives the stop signal.

[0089] In the solution of this example, when the active arm 70 rotates to the first limit position in the clockwise direction, the induction block 130 triggers the first limit switch 150, the motor 60 stops working, and the active arm 70 stops rotating. Similarly, when the active arm 70 rotates to the second limit position in the counterclockwise direction, the motor 60 stops working, and the active arm 70 stops rotating. Therefore, by setting the first limit switch 150, the second limit switch 160 and the induction block 130, the active arm 70 can be limited, thereby preventing the moving platform 10 from running over, and improving the overall operation safety of the device.

[0090] For example, Figure 7 As shown, a first limiting column 170 is provided on the base 40, and when the active arm 70 rotates in the clockwise direction to the third extreme position, the active arm 70 conflicts with the first limiting column 170; and / or, a second limiting column 140 is provided on the base 40, and when the active arm 70 rotates in the counterclockwise direction to the fourth extreme position, the active arm 70 conflicts with the second limiting column 140.

[0091] In some embodiments, only the first limiting column 170 may be provided. In other embodiments, only the second limiting column 140 may be provided. In still other embodiments, both the first limiting column 170 and the second limiting column 140 may be provided.

[0092] In the scheme of this example, when the active arm 70 rotates to the third limit position in the clockwise direction, the active arm 70 conflicts with the first limit column 170, and / or, when the active arm 70 rotates to the fourth limit position in the counterclockwise direction, the active arm 70 conflicts with the second limit column 140, thereby, the active arm 70 can be mechanically limited in the clockwise direction and / or counterclockwise direction to avoid the moving platform 10 from running too far, thereby improving the overall operation safety of the device. In the above-mentioned embodiment of setting the first limit switch 150, the second limit switch 160 and the sensor block 130, further setting the first limit column 170 and the second limit column 140 can play a role of multiple limits, thereby avoiding the moving platform 10 from running too far due to the failure of the limit switch, thereby further improving the operation safety of the device.

[0093] Optionally, the first limit position does not exceed the third limit position in the clockwise direction, and the second limit position does not exceed the fourth limit position in the clockwise direction. That is, the first limit position can be the same as the third limit position, or located in front of the third limit position in the clockwise direction; the second limit position can be the same as the fourth limit position, or located in front of the fourth limit position in the counterclockwise direction. In this way, it is possible to avoid the mechanical limit from affecting the functioning of the limit switch.

[0094] For example, the first limit position is located in front of the third limit position in the clockwise direction; and / or the second limit position is located in front of the fourth limit position in the counterclockwise direction. This setting can avoid the mechanical limit from affecting the functioning of the limit switch, which helps to achieve the effect of multiple limits more reasonably.

[0095] For example, Figure 1-4 As shown, the control device also includes a support assembly arranged between the moving platform 10 and the base 40, and the number of the support assemblies is two groups, and the two groups of support assemblies are arranged in parallel on the front and rear sides of the driving assembly; the support assembly includes a first support rod 30 and a second support rod 20 arranged in an X-shape, and the middle part of the first support rod 30 is hinged to the middle part of the second support rod 20; the first end of the first support rod 30 is hinged to the moving platform 10, and the second end of the first support rod 30 is slidably connected to the base 40; the first end of the second support rod 20 is slidably connected to the moving platform 10, and the second end of the second support rod 20 is slidably connected to the base 40.

[0096] See also Figure 1-4 , Fig.10 The movable platform 10 may include a top plate 101 and a side plate 102, wherein the side plate 102 is installed below the top plate 101. The side plate 102 is provided with a first slide groove 103 and a hinge hole 104. The first end of the first support rod 30 is hinged to the movable platform 10 through the hinge hole 104, and the first end of the second support rod 20 is hinged to the first slide groove 103. During the operation of the control device, the second support rod 20 can slide relative to the first slide groove 103.

[0097] like Figure 1-4 , Figure 6 As shown, the base 40 further includes a mounting plate 401. The mounting plate 401 is vertically mounted on the base bracket 402. The mounting plate 401 is provided with a second slide groove 404 and a third slide groove 405. The second end of the first support rod 30 is hinged to the third slide groove 405, and the second end of the second support rod 20 is hinged to the second slide groove 404. During the operation of the control device, the first support rod 30 can slide relative to the third slide groove 405, and the second support rod 20 can slide relative to the second slide groove 404.

[0098] In such Fig. 9In the illustrated embodiment, the two groups of support assemblies are connected by a connecting shaft 100. Specifically, there are four connecting shafts 100, and the four connecting shafts 100 are respectively used to connect the same ends of the corresponding support rods in the two groups of support assemblies. For example, the first end of the first support rod 30 in the first group of support assemblies is connected to the first end of the first support rod 30 in the second group of support assemblies by the connecting shaft 100. The connection methods of other support rods and ends are similar and will not be repeated.

[0099] In such Figure 1 , Fig. 9 In the illustrated embodiment, the first end of the first support rod 30 is hinged to the hinge hole 104 of the movable platform 10 via the connecting shaft 100 connected thereto. The second end of the first support rod 30 is hinged in the third slide groove 405 via the connecting shaft 100 connected thereto, and can slide relative to the third slide groove 405. The first end of the second support rod 20 is hinged in the first slide groove 103 via the connecting shaft 100 connected thereto, and can slide relative to the first slide groove 103. The second end of the second support rod 20 is hinged in the second slide groove 404 via the connecting shaft 100 connected thereto, and can slide relative to the second slide groove 404.

[0100] The above technical solution can play an auxiliary supporting role for the moving platform 10 by setting the first support rod 30 and the second support rod 20 in an X-shaped cross arrangement, thereby reducing the load borne by the driving assembly, thereby helping to improve the overall load-bearing capacity and operating stability of the device. In addition, the solution can use a connecting shaft 100 to connect the two groups of support assemblies. This arrangement helps to improve the overall structural strength, thereby helping to further increase the load-bearing capacity of the device.

Multiple groups of operating parameters may be preset in the controller, and each group of operating parameters is used to enable the power assembly to control the moving platform 10 to move along different operating trajectories. Optionally, the control device may further include a display panel, on which different operating trajectories may be displayed, and the user may select the required operating trajectory on the display panel. After the user completes the selection, the controller may send the corresponding operating parameters to the motor 60 corresponding to the two groups of power assemblies one by one, so as to control the moving platform 10 to operate according to the user's needs.
