Description

Technical Field

[0001] This application relates to the field of furniture technology, and in particular to infant cradles and their bases. Background Technology

[0002] Currently, infant cradles are widely used in the market. To meet the comfort and sleep needs of infants, people expect cradles to offer a variety of swinging patterns.

[0003] In related technologies, the base of an infant cradle is usually equipped with at least two motion mechanisms. These two motion mechanisms are connected by various complex support structures, thereby superimposing the two motion modes of the two motion mechanisms to increase the swinging modes of the infant cradle.

[0004] However, this design has many drawbacks. On the one hand, the complex support structure significantly increases the height of the base, raising the overall center of gravity of the infant cradle considerably. This makes it prone to wobbling and tipping during use, posing a safety hazard due to poor base stability and seriously threatening the safety of infants. On the other hand, the complex support structure not only requires more parts, increasing the complexity of the manufacturing process, but also demands higher processing precision, leading to a significant increase in production costs. This hinders the large-scale promotion and popularization of this type of infant cradle in the market. Summary of the Invention

[0005] Therefore, it is necessary to provide an infant comfort cradle and its base to address the problems of unstable center of gravity and high cost caused by connecting at least two motion mechanisms through multiple complex supports.

[0006] An infant comfort cradle, the base of which includes:

[0007] Bottom shell;

[0008] The first drive mechanism is fixed inside the bottom shell;

[0009] The second drive mechanism is slidably connected to the bottom shell along the first direction. The first drive mechanism is drively connected to the second drive mechanism. The first drive mechanism is used to drive the second drive mechanism to slide along the first direction.

[0010] An exercise support is used for fixed connection with a cradle. The exercise support has a first end and a second end along a second direction. The first end is slidably connected to the bottom shell along the first direction, and the first end is rotatably connected to the bottom shell about the axis of the first direction. A second drive mechanism is fixedly connected to the second end along the first direction, and the second drive mechanism is also drively connected to the second end, for driving the second end to swing up and down along an arc trajectory about the axis of the first direction.

[0011] In one embodiment, one of the base shell and the motion bracket is provided with a rotating shaft extending along a first direction, and the other is provided with a slider that slides with the rotating shaft along the first direction, the length of the slider along the first direction being less than the length of the rotating shaft.

[0012] In one embodiment, the second drive mechanism includes a power component and a connecting bracket fixedly connected to the power component. The connecting bracket is slidably connected to the bottom shell along a first direction. The first drive mechanism is drively connected to the connecting bracket. The power component is fixedly connected to the second end along the first direction.

[0013] In one embodiment, the first driving mechanism includes a first eccentric shaft extending in a second direction, and the connecting bracket has a limiting groove extending in a vertical direction, wherein the first eccentric shaft and the limiting groove are slidably connected in a vertical direction.

[0014] In one embodiment, the motion support is provided with a rotating shaft extending in a first direction, and the bottom shell is provided with a slider that slides with the rotating shaft in the first direction.

[0015] The second drive mechanism includes a second eccentric shaft extending along a first direction, and the motion support includes:

[0016] The first swing arm has a first rotating part and a second rotating part that are coaxially and spaced apart, and the first rotating part is rotatably connected to the second eccentric shaft.

[0017] A second swing arm extends along the second direction, and one end of the second swing arm is rotatably connected to the second rotating part; and

[0018] The connecting wall is fixedly connected to the rotating shaft, and the other end of the second swing arm is slidably connected to the connecting wall along the second direction.

[0019] In one embodiment, the second drive mechanism further includes a second motor and a second worm gear assembly, the second motor being connected to the worm gear in the second worm gear assembly, and the axial direction of the worm in the second worm gear assembly being a first direction;

[0020] The turbine is provided with a second eccentric shaft at both ends along the axial direction, and each second eccentric shaft is rotatably connected to the corresponding second swing arm through the first swing arm.

[0021] In one embodiment, the connecting wall has two through holes along the second direction;

[0022] The two second swing arms are respectively located on both sides of the connecting wall along the first direction, and the other end of the second swing arm passes through the corresponding through hole so as to be able to slide relative to the through hole.

[0023] In one embodiment, both the first drive mechanism and the second drive mechanism are located between the two second swing arms.

[0024] In one embodiment, a control module is provided on the bottom shell, and speed sensors are respectively provided on the first drive mechanism and the second drive mechanism. The control module is used to adjust the speed of the first drive mechanism and the second drive mechanism according to the real-time speed detected by the speed sensors.

[0025] An infant comfort cradle includes a cradle and a base for the infant comfort cradle, wherein the cradle is fixedly connected to the motion support.

[0026] The aforementioned infant comfort cradle and its base have a first drive mechanism that can drive a second drive mechanism to slide along a first direction. The second drive mechanism then drives a motion support to slide along the first direction. At the same time, the second drive mechanism can also directly drive the second drive mechanism to rotate around the first end. That is, the first drive mechanism and the second drive mechanism can be connected by only one layer of motion support, which is simple in structure. Moreover, the first drive mechanism is directly fixed to the bottom shell, and the second drive mechanism is slidably connected to the bottom shell. This means that the second drive mechanism is also set on the bottom shell, which eliminates the need for the first drive mechanism and the second drive mechanism to be superimposed in the height direction. This reduces the height of the base and improves the stability of the base. Attached Figure Description

Detailed Implementation

[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0036] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0039] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0040] In related technologies, the base of an infant soothing cradle includes a first drive mechanism, a second drive mechanism, and at least two support frames. The first support frame is mounted on the first drive mechanism, the second support frame is mounted on the second drive mechanism, and the second drive mechanism is mounted on the first support frame. That is, when the first drive mechanism moves, it can drive the second drive mechanism and the second support frame to move simultaneously via the first support frame; conversely, when the second drive mechanism moves, it can drive the second support frame to move, thus achieving a superposition of the two movement modes. However, this method requires two support frames, resulting in a complex structure; and the first and second drive mechanisms are superimposed in the height direction, leading to instability at the center of gravity.

[0041] Combination Figures 1-3This application provides a base for an infant soothing cradle. The base 10 includes a bottom shell 100, a first drive mechanism 200, a second drive mechanism 300, and a motion support 400. The first drive mechanism 200 is fixed inside the bottom shell 100; the second drive mechanism 300 is slidably connected to the bottom shell 100 along a first direction OX, and the first drive mechanism 200 is driveably connected to the second drive mechanism 300 along the first direction OX; the motion support 400 is fixedly connected to the cradle 20, and the motion support 400 has a first end 410 and a second end 420 along a second direction OY. The first end 410 is slidably connected to the bottom shell 100 along the first direction OX, and simultaneously, the first end 410 and the bottom shell 100 are rotatably connected about the axis of the first direction OX; the second drive mechanism 300 is fixedly connected to the second end 420 along the first direction OX, and the second drive mechanism 300 is driveably connected to the second end 420, and is driveably connected to drive the second end 420 to swing up and down along an arc trajectory about the axis of the first direction OX.

[0042] In this embodiment, the first end 410 of the motion bracket 400 is slidably connected to the base shell 100 along the first direction OX, and the second end 420 is fixed to the second drive mechanism 300 along the second direction OY. The second drive mechanism 300 is slidably connected to the base shell 100 along the first direction OX. Therefore, when the first drive mechanism 200 drives the second drive mechanism 300 to slide along the first direction OX, firstly, the second drive mechanism 300 slides relative to the base 10 along the first direction OX. At the same time, since the second drive mechanism 300 is fixedly connected to the second end 420 along the first direction OX, the second drive mechanism 300 can drive the motion bracket 400 to slide relative to the base 10 along the first direction OX, thereby facilitating the movement of the cradle 20 located on the base 10 along the first direction OX. The second drive mechanism 300 is driveably connected to the second end 420 and is used to drive the second end 420 to swing up and down around the first end 410 along an arc trajectory, so that the motion bracket 400 can also drive the cradle 20 to swing up and down.

[0043] In this application, the first drive mechanism 200 directly drives the second drive mechanism 300 to slide along the first direction OX, and the second drive mechanism 300 drives the motion bracket 400 to slide along the first direction OX. At the same time, the second drive mechanism 300 can also directly drive the second drive mechanism 300 to rotate around the first end 410. That is, the first drive mechanism 200 and the second drive mechanism 300 can be connected by only one layer of motion bracket 400, which is simple in structure. Moreover, the first drive mechanism 200 is directly fixed on the bottom shell 100, and the second drive mechanism 300 is slidably connected to the bottom shell 100. That is, the second drive mechanism 300 is also set on the bottom shell 100. That is, there is no need for the first drive mechanism 200 and the second drive mechanism 300 to be superimposed in the height direction, thereby reducing the height of the base 10 and improving the stability of the base 10.

[0044] The first direction OX can be the width direction of the infant cradle, the second direction OY can be the length direction of the infant cradle, and the third direction OY can be the height direction of the infant cradle.

[0045] In some embodiments, one of the base shell 100 and the motion bracket 400 is provided with a rotating shaft 430 extending along the first direction OX, and the other is provided with a slider 110 that slides with the rotating shaft 430 along the first direction OX, wherein the length of the slider 110 along the first direction OX is less than the length of the rotating shaft 430.

[0046] In some embodiments, the bottom shell 100 is provided with a rotating shaft 430 extending along a first direction OX, and the motion bracket 400 is provided with a slider 110 that slides along the rotating shaft 430 along the first direction OX. The length of the slider 110 along the first direction OX is less than the length of the rotating shaft 430. On one hand, the slider 110 is sleeved outside the rotating shaft 430, so it can rotate relative to the rotating shaft 430, so that when the second drive mechanism 300 drives the motion bracket 400, the motion bracket 400 can rotate directly around the rotating shaft 430 via the slider 110. On the other hand, the rotating shaft 430 and the slider 110 slide along the first direction OX, so that when the first drive mechanism 200 drives the motion bracket 400 through the second drive mechanism 300, the motion bracket 400 can slide along the first direction OX on the rotating shaft 430 via the slider 110.

[0047] In other embodiments, combined with Figure 2The motion support 400 is provided with a rotating shaft 430 extending along the first direction OX, and the bottom shell 100 is provided with a slider 110 that slides with the rotating shaft 430 along the first direction OX. The length of the slider 110 along the first direction OX is less than the length of the rotating shaft 430. This allows for both rotational and sliding connections between the motion support 400 and the bottom shell 100. Specifically, the first end 410 of the motion support 400 has ears 431 on both sides along the first direction OX. The two ends of the rotating shaft 430 are fixedly connected to the corresponding ears 431. The ears 431 are spaced apart from the bottom shell 100, allowing the motion support 400 to drive the rotating shaft 430 to rotate relative to the slider 110 on the bottom shell 100 via the ears 431.

[0048] Of course, in other embodiments, the motion support can also be slidably connected to the base shell in other ways. For example, a linear guide rail is fixed on the base shell, and a matching slider is installed at the first end of the motion support. The slider can slide along the guide rail in the first direction OX. At the same time, the slider is hinged to the motion support, allowing the motion support to rotate around the axis of rotation, realizing a combined sliding and rotational motion.

[0049] In some embodiments, combined with Figure 2 and Figure 3 The second drive mechanism 300 includes a power component 310 and a connecting bracket 320 fixedly connected to the power component 310. The connecting bracket 320 is slidably connected to the bottom shell 100 along the first direction OX. The first drive mechanism 200 is drively connected to the connecting bracket 320. The power component 310 is fixedly connected to the second end 420 along the first direction OX.

[0050] In this embodiment, the first drive mechanism 200 is connected to the connecting bracket 320 in a transmission manner. When the first drive mechanism 200 is activated, it drives the connecting bracket 320 to slide relative to the bottom shell 100 along the first direction OX. At the same time, since the power component 310 is fixedly connected to the connecting bracket 320, the connecting bracket 320 slides by driving the power component 310 to slide along the first direction OX. Since the power component 310 is fixedly connected to the second end 420 along the first direction OX, the power component 310 can drive the motion bracket 400 to slide along the first direction OX.

[0051] The first end 410 of the motion support 400 is directly slidably connected to the base shell 100, and the second end 420 is slidably connected to the base shell 100 via a connecting bracket 320, which is used to ensure the stability of the motion support 400 when sliding along the first direction OX. Specifically, the base shell 100 is provided with a guide shaft 470 extending along the first direction OX, and the connecting bracket 320 is slidably connected to the guide shaft 470 at the middle of the first direction OX.

[0052] Furthermore, in combination Figure 2The first drive mechanism 200 includes a first eccentric shaft 210 extending along the second direction OY, and a limiting groove 321 extending along the vertical direction OZ is provided on the connecting bracket 320. The first eccentric shaft 210 and the limiting groove 321 are slidably connected along the vertical direction OZ.

[0053] An eccentric shaft is a special type of shaft part whose axis does not coincide with the center of rotation. The part of the shaft used to install transmission components (the eccentric part) has a certain eccentricity relative to the center of the shaft. Structurally, an eccentric shaft includes a shaft body, an eccentric section, and a connecting part. The eccentric section is offset from the central axis of the shaft body.

[0054] In this embodiment, the first eccentric shaft 210 is slidably connected to the limiting groove 321 in the vertical direction OZ, so that when the first eccentric shaft 210 rotates, the first eccentric shaft 210 can move within the limiting groove 321, so as to avoid the first eccentric shaft 210 driving the second driving mechanism 300 to move in the vertical direction OZ when it rotates. At the same time, when the first eccentric shaft 210 rotates, it can drive the second driving mechanism 300 to move in the first direction OX.

[0055] Combination Figure 5 The first drive mechanism 200 includes a first worm gear assembly and a first motor 240. The first motor 240 is connected to the worm gear in the first worm gear assembly. The axial direction of the worm in the first worm gear assembly is the second direction OY. The worm in the first worm gear assembly is coaxially arranged with the first eccentric shaft 210.

[0056] In some other embodiments, the first drive mechanism 200 may be a linear motion mechanism, such as a linear motor or a lead screw and nut mechanism, which is used to directly drive the second drive mechanism 300 to move along the first direction OX.

[0057] In some embodiments, combined with Figure 3 and Figure 4 The motion support 400 is provided with a rotating shaft 430 extending along the first direction OX, and the bottom shell 100 is provided with a slider 110 that slides with the rotating shaft 430 along the first direction OX. The second drive mechanism 300 includes a second eccentric shaft 315 extending along the first direction OX. The motion support 400 includes a first swing arm 440, a second swing arm 450, and a connecting wall 460. The first swing arm 440 has a first rotating part 441 and a second rotating part 442 that are coaxially spaced apart. The first rotating part 441 is rotatably connected to the second eccentric shaft 315. The second swing arm 450 extends along the second direction OY, and one end of the second swing arm 450 is rotatably connected to the second rotating part 442. The connecting wall 460 is fixedly connected to the rotating shaft 430, and the other end of the second swing arm 450 is slidably connected to the connecting wall 460 along the second direction OY.

[0058] In this embodiment, the second eccentric shaft 315 of the second drive mechanism 300, which rotates around the first direction OX, forms a crank-rocker-like linkage structure with the first swing arm 440, the second swing arm 450, and the connecting wall 460 of the motion bracket 400. This structure converts the circular rotation of the second eccentric shaft 315 into an arc-shaped swing of the motion bracket 400 around the first end 410 in the vertical direction OZ. This arc-shaped swing can meet the needs of infants and young children for different soothing rhythms. Furthermore, in the first direction OX, the second drive mechanism 300 is directly rotatably connected to the first swing arm 440 of the motion bracket 400 via the second eccentric shaft 315, so that the second drive mechanism 300 and the second end 420 move synchronously along the first direction OX, thereby allowing the movement of the first drive mechanism 200 along the first direction OX to be transmitted to the motion bracket 400 through the second drive mechanism 300.

[0059] In some embodiments, combined with Figure 6 The second drive mechanism 300 also includes a second motor 311 and a second worm gear assembly 312. The second motor 311 is connected to the worm gear in the second worm gear assembly 312. The axial direction of the worm in the second worm gear assembly 312 is the first direction OX. The two ends of the worm along the axial direction are respectively provided with second eccentric shafts 315. Each second eccentric shaft 315 is rotatably connected to the corresponding second swing arm 450 through a first swing arm 440.

[0060] In this embodiment, the second worm gear assembly 312 simultaneously drives the second eccentric shaft 315 to rotate. The two eccentric shafts are connected to the two sides of the motion bracket 400 along the first direction OX to ensure the motion stability of the motion bracket 400.

[0061] Furthermore, the connecting wall 460 has two through holes 461 along the second direction OY; two second swing arms 450 are respectively located on both sides of the connecting wall 460 along the first direction OX, and the other end of the second swing arm 450 passes through the corresponding through hole 461 so as to be able to slide relative to the through hole 461.

[0062] In this embodiment, the second swing arm 450 is a cylindrical structure. The second swing arm 450 passes through the through hole 461 so that when the second drive mechanism 300 drives the second eccentric shaft 315 to rotate, the second eccentric shaft 315 drives the second swing arm 450 to swing in an OZ arc in the vertical direction through the first swing arm 440, and the second swing arm 450 can extend and retract within the through hole 461.

[0063] In some embodiments, the first drive mechanism 200 and the second drive mechanism 300 are both located between the two second swing arms 450.

[0064] In this embodiment, the first drive mechanism 200 and the second drive mechanism 300 are both located between the two second swing arms 450, so that the first drive mechanism 200 and the second drive mechanism 300 are at the same height as the motion support 400, which helps to lower the center of gravity of the base 10 and improve the stability of the base 10.

[0065] In some embodiments, a control module 500 is provided on the bottom shell 100, and a speed sensor 510 is provided on the first drive mechanism 200 and the second drive mechanism 300 respectively. The control module 500 is used to adjust the speed of the first drive mechanism 200 and the second drive mechanism 300 according to the real-time speed detected by the speed sensor 510.

[0066] In this embodiment, the speed sensor 510 includes a grating and a detection head. The grating on the first drive mechanism 200 is disposed at one end of the worm in the first worm gear assembly, and the grating on the second drive mechanism 300 is disposed at one end of the worm in the second worm gear assembly. Each grating is equipped with a detection head, which is electrically connected to the control module 500. The speed sensor 510 is used to monitor the rotational speed of the corresponding worm and transmit it to the control module 500. The control module 500 is used to adjust the rotational speed of the first drive mechanism 200 and the second drive mechanism 300 according to the real-time speed detected by the speed sensor 510, so as to fit the rotational speed of the first drive mechanism 200 and the second drive mechanism 300 to the cradle 20 to produce a rocking pattern similar to "u", "o", "w" trajectories.

[0067] In some embodiments, in order to enable the first motor 240 to decelerate to a suitable speed to drive the first worm gear assembly 230, the first drive mechanism 200 further includes a first reduction component 220. Similarly, in order to reduce the speed of the second motor 311, the second drive mechanism 300 further includes a second reduction component 314. Both the first reduction component 220 and the second reduction component 314 are connected by a first gear, a second gear, and a belt. The first gear and the second gear are driven by the belt. The diameter of the first gear is larger than the diameter of the second gear. The first motor 240 and the second motor 311 are respectively coaxially connected to their corresponding second gears. The worm of the first worm gear assembly 230 and the worm of the second worm gear assembly are respectively coaxially connected to their corresponding first gears.

[0068] An embodiment of this application also discloses an infant comfort cradle, including a cradle 20 and a base 10 for the infant comfort cradle, wherein the cradle 20 is fixedly connected to a motion support 400.

[0069] In this embodiment, the motion support 400 is provided with a support rod extending in the vertical direction OZ. The motion support 400 is connected to the cradle 20 through the support rod. When the motion support 400 moves, it can synchronously drive the cradle 20 to move. The movement of the motion support 400 includes sliding along the first direction OX and oscillating in an arc around the first end 410 in the vertical direction OZ. The two movement modes can be implemented individually or simultaneously. When the two movement modes are implemented simultaneously, the cradle 20 can produce a swaying pattern with trajectories similar to "u", "o", and "w".
