[0037] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0038] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time. On the contrary, when an element is referred to as being "directly on" another element, there is no intermediate element. The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0039] Please refer to Figures 1 to 5 An electric baby cradle includes a base 10, an elastic support 20, a cradle core 30 and an adjustment buckle 40. The elastic support 20 is used to install a mattress. The elastic support 20 is a closed loop structure arranged obliquely. A connecting buckle 21 is provided at the bottom of the elastic support 20. The angle between the connecting buckle 21 and the elastic support 20 is an acute angle. Please refer to Figure 6 The cradle core 30 includes a fixed seat 31, a movable seat 32, a driving device 33, a driving rod 34 and a driven rod 35. The fixed seat 31 is fixed to the base 10, the movable seat 32 is movably arranged above the fixed seat 31, the driving device 33 is arranged in the fixed seat 31, one end of the driving rod 34 and the driven rod 35 are respectively connected to the fixed seat 31, and the other end is respectively connected to the movable seat 32. The driving device 33 is used to drive the driving rod 34 to swing, and the movable seat 32 is movably connected to the elastic support 20; Figure 7 As shown, one end of the adjustment buckle 40 is embedded in the movable seat 32 , and the other end is provided with a U-shaped groove 411 opening downward, and the inner side wall of the U-shaped groove 411 is provided with at least one fixing groove 412 that is snap-fitted with the connecting buckle 21 .

[0040] Specifically, the elastic support 20 is the load-bearing part of the cradle, and an iron rod can be bent into a closed loop structure. The connecting buckle 21 is set in a U shape, and the open end of the connecting buckle 21 is fixedly connected to the elastic support 20. Preferably, the U-shaped connecting buckle 21 can be integrally bent on the bottom side rod body of the elastic support 20 through a bending process, which can simplify the manufacturing process and ensure sufficient structural strength. The mattress is covered on the rod body of the elastic support 20, and the infant can lie directly on the mattress. Since the mattress itself is made of soft material, it will form a depression, so the infant will be positioned in the depression and will not be displaced. Since the elastic support 20 is elastic, after the guardian connects the connecting buckle 21 to the fixing groove 412 of the adjusting buckle 40, the posture of the elastic support 20 is fixed. When the infant is rocked, the elastic force of the elastic support 20 itself will be fed back, making the infant feel interesting in the cradle. Since the elasticity of the elastic support 20 is not particularly strong, the elastic force feedback will not be very large, and there is no need to worry about the infant not bouncing off the cradle, so it is safe and reliable.

[0041] The electric baby cradle bed drives the driving rod 34 and the driven rod 35 to swing through the driving device 33, and the movable seat 32 can swing relative to the fixed seat 31 under the drive of the driving rod 34 and the driven rod 35, and then drive the elastic support 20 to swing, thereby realizing the automatic swing function of the cradle, saving time and effort. When the electric baby cradle bed is in an idle state, the connecting buckle 21 can be withdrawn from the fixing groove 412, and then it can be withdrawn from the opening of the U-shaped groove 411, so that the elastic support 20 can be laid flat, and the electric baby cradle can be folded, which is simple to operate and easy to store.

[0042] In one embodiment, the inner side wall of the U-shaped groove 411 is provided with a plurality of fixing grooves 412 from top to bottom. By providing a plurality of fixing grooves 412, multi-level adjustment of the posture of the electric baby cradle can be achieved. The number of the fixing grooves 412 can be set to two, three or more as required. For example, a fixing groove 412 may be horizontally opened on one side wall of the U-shaped groove 411 at the top, middle and bottom respectively. Since the adjustment buckle 40 has three fixing grooves 412, the elastic support 20 can be positioned and adjusted in three stages. When the guardian needs to change the posture of the cradle, the guardian can complete the positioning by returning the top of the connecting buckle 21 from the current fixing groove 412 to the U-shaped groove 411, and then moving it to the target fixing groove 412 and pushing it in. Because the connecting buckle 21 and the elastic support 20 are fixedly connected, the connection is rigid and stable. When the cradle needs to be stored, the guardian only needs to return the top of the connecting buckle 21 from the fixing groove 412, and then withdraw it from the opening of the U-shaped groove 411 to lay the elastic support 20 flat, so that the electric baby cradle can be folded for easy storage. For another example, Figure 7 As shown, two fixing grooves 412 may also be provided to achieve two-stage positioning adjustment of the elastic support 20 .

[0043] Furthermore, the adjustment buckle 40 includes a reinforcement extension section embedded in the movable seat 32, and a hollow circular protrusion is provided on the top surface of the reinforcement extension section. This arrangement makes the adjustment buckle 40 have excellent use strength, and is not easy to be displaced or even broken due to the pressure of the elastic support 20 to cause danger, thereby ensuring the safety of the electric baby cradle.

[0044] In order to further ensure the safety of the electric baby cradle, in one embodiment, Figure 7 As shown, the adjustment buckle 40 includes a buckle body 41 and a protective buckle 42. The buckle body 41 is provided with a U-shaped groove 411. The protective buckle 42 is movably connected to the bottom of the buckle body 41. The protective buckle 42 is used to open or close the opening of the U-shaped groove. When the electric baby cradle is in use, the protective buckle 42 always closes the opening of the U-shaped groove 411 (such as Figure 8As shown in the figure), the connection buckle 21 can be prevented from slipping off from the opening and causing the cradle to fold accidentally, thereby ensuring the safety performance of the cradle. When the electric baby cradle needs to be stored, the protective buckle 42 opens the opening of the U-shaped groove 411 (as shown in the figure). Fig. 9 As shown), so that the connecting buckle 21 can be moved out of the opening to complete the folding.

[0045] For further information, please refer to Figure 8 and Fig. 9 The protective buckle 42 is rotatably connected to the buckle body 41, and a clamping portion 421 is provided at the end of the protective buckle 42. The two opposite side walls of the U-shaped groove 411 are respectively provided with a first clamping groove 413 and a second clamping groove 414. The first clamping groove 413 and the fixed groove 412 are arranged on the same side wall of the U-shaped groove. When the clamping portion 421 is clamped in the first clamping groove 413, the opening part of the U-shaped groove is closed, and when the clamping portion 421 is clamped in the second clamping groove 414, the opening part of the U-shaped groove is opened.

[0046] Specifically, the first card slot 413 and the fixed slot 412 are both provided on the side of the U-shaped slot 411 close to the movable seat 32, the first card slot 413 is located below the fixed slot 412, and the protective buckle 42 is rotatably connected to the side of the buckle body 41 away from the movable seat 32 through a rotating shaft. When the electric baby cradle is in normal use, the protective buckle 42 is in a protective state, and the clamping portion 421 of the protective buckle 42 is clamped in the first card slot 413, and the protective buckle 42 can close the opening of the U-shaped slot 411. In this way, when the cradle is in use, no matter which angle the user adjusts it to, there will be no danger of accidental folding. When the cradle needs to be stored, the protective buckle 42 is rotated to the open state, and the clamping portion 421 of the protective buckle 42 is clamped in the second card slot 414, so that the opening of the U-shaped slot 411 is opened, and the cradle can be folded, which is simple and convenient to operate, safe and reliable.

[0047] Furthermore, the elastic support 20 is a trapezoidal structure that is narrow at the top and wide at the bottom, the top of the elastic support 20 is bent backwards, and the bending angle between the top of the elastic support 20 and the main body of the elastic support 20 is an obtuse angle. Specifically, the upper part of the elastic support 20 is slightly narrower than the lower part, and the whole is in a trapezoidal shape, and the top bending part and the main body are at an obtuse angle. Under this structure, the lower part of the elastic support 20 can bear more weight and volume, and is more suitable for the body shape of infants and young children, and the head of the infants and young children can relax at the top bending part.

[0048] Furthermore, the fixed seat 31 and the movable seat 32 have mating surfaces on their opposite sides, and the mating surface is at an acute angle to the horizontal plane on the side away from the elastic support 20. In this way, the movable seat 32 and the fixed seat 31 can move relative to each other smoothly, and it is more convenient to support the whole and stabilize the posture.

[0049] For further information, please refer to Figure 2 and Figure 5 The electric baby cradle also includes a sleeve 50, which includes a first sleeve 51 and two second sleeves 52 arranged on the same side of the first sleeve 51. The first sleeve 51 is sleeved on the elastic support 20. A notch 53 is provided in the middle of the first sleeve 51 for the connection buckle 21 to extend out. The two second sleeves 52 are respectively located on opposite sides of the connection buckle 21. Two parallel extending connecting rods 60 are provided on one side of the movable seat 32 close to the elastic support 20. The two connecting rods 60 are respectively plugged and fixed with the corresponding second sleeves 52. Specifically, the sleeve 50 is in a П-shaped structure. The notch 53 reserved in the middle of the first sleeve 51 can be conveniently sleeved with the bottom rod body of the elastic support 20 and allow the connection buckle 21 to extend out. The movable seat 32 can be connected to the elastic support 20 through the cooperation of the connecting rod 60 and the second sleeve 52 to ensure the support strength.

[0050] , please refer to Figure 2 and Figure 6 The driving device 33 includes a driving motor 331 and a gear reduction group 332. The driving motor 331 has a built-in brush. The output end of the driving motor 331 is meshed with the gear reduction group 332 for transmission. The output end of the gear reduction group 332 is meshed with the driving rod 34 for transmission. When it is necessary to automatically rock the cradle, the guardian starts the driving motor 331 through operation. The driving motor 331 will drive the driving rod 34 to rotate at a slow speed under the action of the gear reduction group 332, and the input side of the driving rod 34 will drive the output side to rotate around the input side. Since the driving rod 34 and the driven rod 35 are both connected to the movable seat 32, the driven rod 35 will also be driven by the driving rod 34. Under the drive of the two rods, the movable seat 32 will move horizontally relative to the fixed seat 31. Since the driving motor 331 has a brush, it will detect the rotation of the driving motor 331. Therefore, after the movable seat 32 moves horizontally to a certain extent, it will feedback to the brush of the driving motor 331, so that the driving motor 331 is reversed, and the movable seat 32 is repeatedly translated left and right in the horizontal direction under the action of the driving motor 331, thereby driving the elastic support 20 fixed to the movable seat 32 to complete the automatic rocking operation of the cradle.

[0051] Furthermore, the driving motor 331 is a stepper motor, and the gear reduction group 332 is a three-stage reduction gear group. The stepper motor has good controllability, precise control, and stable torque output, which is beneficial to infants and young children using the cradle, and the three-stage gear reduction group 332 can not only effectively reduce the speed, but also buffer the vibration generated by the motor output end to a certain extent, so that the swing of the cradle is more stable.

[0052] like Figure 6As shown, the driving rod 34 and the driven rod 35 both include a transverse rod, a first bending rod bent downward from one end of the transverse rod, and a second bending rod bent upward from the other end of the transverse rod. Bearings 36 are provided on the first bending rod and the second bending rod. The first bending rod is connected to the fixed seat 31 through the bearing 36, and the second bending rod is connected to the movable seat 32 through the bearing 36.

[0053] Specifically, the driving rod 34 and the driven rod 35 are both in a Z-shaped structure with bent ends, and a pair of bearings 36 are respectively provided on the first bent rod and the second bent rod of the driving rod 34 and the driven rod 35, and one of each pair of bearings 36 is provided at the rod end of the driving rod 34 or the driven rod 35 and fixed to the inner cavity of the housing of the fixed seat 31 or the movable seat 32, while the other is provided at the bending part of the driving rod 34 or the driven rod 35 and fixed to the housing of the fixed seat 31 or the movable seat 32. By providing the bearings 36, it can effectively play the role of stable connection and stable transmission of torque, so that the movement of the movable seat 32 relative to the fixed seat 31 becomes more stable.

[0054] Preferably, the angle between the side of the first bending rod close to the second bending rod and the horizontal plane is acute, so that the driving rod 34 and the driven rod 35 will generate energy conversion between kinetic energy and potential energy during the swinging process, and generate inertia of reciprocating free swinging, so that only an initial driving force is provided by the driving motor 331 to drive the driving rod 34 to swing, and the subsequent swinging process can be maintained only by inertia force, which can effectively save energy consumption.

[0055] Please refer to Figure 1 and Figure 5 In one embodiment, the base 10 includes a decorative piece 11 and two legs 12 connected to the back of the decorative piece 11. The two legs 12 are symmetrically arranged, and the ends of the two legs 12 away from the decorative piece 11 are respectively opened to both sides. Specifically, the cradle core 30 is fixed to the middle of the two legs 12, and the rear ends of the two legs 12 are opened to both sides in an acute angle. In this way, the decorative piece 11, the cradle core 30 and the legs 12 can form a stable support structure to ensure the support stability of the cradle.

[0056] Furthermore, if Figure 5 As shown, each leg 12 is a flat structure, and each leg 12 includes a front supporting section 121 connected to the back of the decorative member 11, and a rear supporting section 122 connected to the rear end of the front supporting section 121. The rear supporting section 122 is bent relative to the front supporting section 121, and the bending angle between the rear supporting section 122 and the front supporting section 121 is an obtuse angle. In this way, the supporting structure of the leg 12 is more stable, which can further ensure the supporting stability of the cradle.

[0057] Preferably, the end of each rear support section 122 is sleeved with a foot 13. By providing the foot 13, the cradle is placed on the ground without slipping, so that the rocking process of the cradle is more stable.

[0058] Further, support pads 111 are respectively provided on both sides of the bottom of the decorative piece 11. By providing the support pads 111, not only can the decorative piece 11 itself be effectively scratched by small debris on the ground, but also can be prevented from being scratched by small debris on the ground.

[0059] Furthermore, an operation panel 112 is provided on the surface of the decorative member 11, and a circuit board electrically connected to the operation panel 112 is provided inside the decorative member 11, and the circuit board is electrically connected to the driving device 33. The setting of the operation panel 112 facilitates the guardian to switch the working mode of the electric baby cradle and more conveniently monitor the working status of the electric baby cradle. For example, a music play button, a volume adjustment button, or a control switch button can be set on the control panel.

[0060] Furthermore, the operation panel 112 may be provided with motion control function keys, and the electric baby cradle may also include a detection module, which is used to detect the shaking state of the elastic support 20. The control module on the circuit board can control the start and stop of the driving device 33 according to the detection results fed back by the detection module.

[0061] Specifically, when the guardian has other things to deal with and needs to leave for a period of time, he can press the motion control function key to switch the cradle to the motion control mode. In the motion control mode, the cradle can intelligently identify the shaking state of the elastic support 20 through the detection module and realize the self-starting function. When the infant in the cradle suddenly wakes up from a deep sleep and starts to turn over and cry, the elastic support 20 will shake. At this time, the detection module detects that the elastic support 20 is shaking and sends a self-starting signal. After receiving the self-starting signal, the control module on the circuit board automatically controls the drive device 33 to start, and the drive device 33 drives the elastic support 20 to swing relative to the base 10, so that the emotions of the infant can be promptly and effectively soothed.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
