DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0019] like Figures 1 to 10 As shown, this embodiment provides an electric cradle drive device, including an upper system 1, a chassis system 2 and a control system. The upper system 1 includes a top seat 3, an upper base 4 and a vertical motion mechanism. The vertical motion mechanism is installed between the top seat 3 and the upper base 4. The vertical motion mechanism includes a double-sided rack 5, a movable block 10, a driving wheel 6 and a driven wheel group. The driving wheel 6 is fixedly connected to the shaft of the first motor 9, the first motor 9 is fixed to the movable block 10, and the two driven wheel groups are respectively rotatably connected to the movable block 10, and the two driven wheel groups are arranged on both sides of the driving wheel 6. The two driven wheel groups include a driven wheel 7 and a first incomplete gear 8. The driven wheel 7 and the first incomplete gear 8 are coaxially arranged. The two driven wheels 7 in the two driven wheel groups are respectively on both sides of the driving wheel 6, and are driven to rotate by the driving wheel 6. The two first incomplete gears 8 are respectively arranged on both sides of the double-sided rack 5, and the teeth on both sides of the two sides are matched respectively.

[0020] In some embodiments, the driven wheel 7 and the first incomplete gear 8 are coaxially arranged front and back, and a rotating shaft passes through the axis of the driven wheel 7 and the first incomplete gear 8, and both ends of the rotating shaft are rotatably connected to the movable block 10, so that the driven wheel group is stably rotatably connected to the movable block 10, thereby improving the overall stability. The first motor 9 includes a reduction box, and the driving wheel 6 is connected to the first motor 9 through the reduction box.

[0021] Specifically, the control system is electrically connected to the first motor 9, and controls the first motor 9 to drive the driving wheel 6 to rotate in the same direction, so that the driven wheels 7 on both sides rotate respectively. The driven wheels 7 drive their respective first incomplete gears 8 to rotate. During the rotation process, the first incomplete gear 8 on the left side of the double-sided rack 5 rotates to mesh with the teeth on the left side of the double-sided rack 5, and continues to rotate so that the first incomplete gear 8 on the left side climbs upward along the teeth on the left side of the double-sided rack 5, driving the movable block 10 to move linearly upward along the double-sided rack 5 until the first incomplete gear 8 on the left side and the teeth are separated from the teeth on the double-sided rack 5, completing the upward linear motion. The driving wheel 6 continues to drive the driven wheel 7 to rotate, and the teeth of the first incomplete gear 8 on the right side of the double-sided rack 5 rotate until the teeth on the right side of the double-sided rack 5 mesh with each other, and continue to rotate so that the first incomplete gear 8 on the right side moves downward along the teeth on the right side of the double-sided rack 5, driving the movable block 10 to move downward along the double-sided rack 5 until the first incomplete gear 8 and teeth on the right side are separated from the teeth on the double-sided rack 5, completing the downward linear motion. The left and right directions in this embodiment are only used to help clarify the content of the technical solution, and do not represent a completely specific position restriction relationship.

[0022] According to the above description, the first motor 9 moves in the same direction, which can be clockwise or counterclockwise, and is designed accordingly according to actual needs. The first motor 9 continues to move in the same direction, driving the movable block 10 to complete the up and down reciprocating linear motion along the double-sided rack 5. The reciprocating motion mechanism set in this embodiment is characterized in that the first motor 9 is kept moving in the same direction, which is used to improve the service life of the overall components of the upper mounting system 1 and avoid the first motor 9 reversing operation to generate a large noise, which affects the baby's sleeping effect.

[0023] like Figure 8 , Fig. 9 and Fig.10The chassis system 2 in this embodiment includes a lower base 11, a single-sided rack 12 and a second incomplete gear 13. A rolling bearing 14 is symmetrically mounted on the lower base 11. The single-sided rack 12 is also symmetrically configured, and the teeth are opposite. The rolling bearing 14 is correspondingly mounted in the curved track groove 15 set on the two single-sided racks 12, so that the curved track groove 15 of the single-sided rack 12 moves relatively left and right along the roller bearing. The curved track groove 15 and the rolling bearing 14 are clearance-matched, and the curved track groove 15 with different curvatures and ups and downs is set accordingly according to actual needs. The upper system 1 is installed above the two single-sided racks 12. The second motor 16 and the second incomplete gear 13 are both installed between the two single-sided racks 12, and the second motor 16 is fixed on the lower base 11, and the shaft of the second motor 16 is fixedly connected to the second incomplete gear 13. The second incomplete gear 13 is matched with the single-sided racks 12 on both sides. Specifically, when the control system controls the second motor 16 to drive the second incomplete gear 13 to rotate in the same direction, the second incomplete gear 13 and the two single-sided racks 12 are alternately meshed, pushing the curved track groove 15 of the single-sided rack 12 to move relatively left and right along the rolling bearing 14, so that the upper system 1 drives the cradle body to achieve left and right high and low reciprocating motion. Among them, the second incomplete gear 13 and the two single-sided racks 12 are alternately meshed, specifically, when the second incomplete gear 13 continues to rotate in the same direction, the teeth on the second incomplete gear 13 are meshed with one of the single-sided racks 12, pushing the single-sided rack 12 to move left until the teeth on the second incomplete gear 13 are separated from the teeth on the single-sided rack 12, that is, the leftward movement is completed. The second incomplete gear 13 continues to rotate, and the teeth of the second incomplete gear 13 mesh with the teeth on the other single-sided rack 12, driving the single-sided rack 12 to move rightward until the teeth on the second incomplete gear 13 separate from the teeth on the single-sided rack 12, that is, the rightward movement is completed. The second motor 16 is continuously controlled to rotate in the same direction, so that the single-sided rack 12 drives the upper mounting system 1 to achieve left and right high and low reciprocating motion.

[0024] The second motor 16 in the above-mentioned chassis system 2 can run in the same direction to produce left and right up and down movements, avoiding the noise problem caused by the movement behavior generated by the motor reversing in actual applications. The design of this embodiment helps to increase the service life of the overall components of the chassis system 2 and improve the safety of infant use.

[0025] In some embodiments, the curved track groove 15 of the single-sided rack 12 is replaced with a straight track groove. When the second motor 16 drives the movement, the single-sided rack 12 drives the upper mounting system 1 to perform only a simple left and right reciprocating motion, so as to take corresponding replacement measures according to actual conditions.

[0026] In some embodiments, Figure 5The upper mounting system 1 includes a guide column 17, and a guide groove is provided on the corresponding movable block 10. The guide column 17 passes through the guide groove and is installed between the top seat 3 and the upper base 4. This arrangement is conducive to the movable block 10 to move up and down in a straight line. The movable block 10 can move up and down along the guide column 17 in a straight line to avoid deviation, play a precise guiding role, and improve the accuracy and stability of the operation of the upper mounting system 1.

[0027] In some embodiments, Figure 5 , a fixed column 18 is installed on the upper base 4, one end of the spring 19 is sleeved on the fixed column 18, and the other end is always in contact with the movable block 10. When the movable block 10 moves upward, the spring 19 plays an elastic supporting force on the movable block 10, relieves the weight brought by the cradle body installed on the movable block 10, and avoids the problem of excessive force during the rotation of the second motor 16, which is conducive to the movable block 10 to drive the cradle body to rise easily. When the movable block 10 moves downward, the overall weight of the movable block 10 and the cradle body compresses the spring 19, which is conducive to the movable block 10 to drive the cradle body to move slowly downward, improve the stability during the movement, and improve the safety and comfort of the cradle body moving up and down. In addition, the spring 19 alleviates the noise generated by the up and down movement of the movable block 10, so that the entire device is in a silent operation state.

[0028] In some embodiments, Figure 6 A pulley 20 is rotatably connected in the guide groove on the movable block 10, and the pulley 20 is arranged in contact with the guide column 17. When the movable block 10 moves up and down along the guide column 17, the pulley 20 rotates under the action of the guide column 17, reducing the friction generated by the interaction between the movable block 10 and the guide column 17, so that the movable block 10 moves up and down smoothly.

[0029] In some implementations, such as Figure 3 The double-sided rack 5 includes a first tooth plate 21. The teeth are respectively arranged on both sides of the first tooth plate 21, and the first tooth plate 21 is provided with first reinforcing ribs 22 arranged crosswise in sequence. That is, the first reinforcing ribs 22 are arranged on the first tooth plate 21, so that the overall structure of the first tooth plate 21 is more stable, thereby improving the supporting strength of the first tooth plate 21 and ensuring the stable assembly of the cradle body and the upper mounting system 1.

[0030] In some embodiments, Figure 7 The chassis system 2 further includes a connecting plate 23, which is mounted above the two single-sided racks 12. The upper base 4 in the upper mounting system 1 is fixedly mounted above the upper connecting plate 23. The connecting plate 23 is provided to facilitate the overall disassembly and assembly of the upper mounting system 1 and to avoid damage to the single-sided racks 12 during the disassembly process.

[0031] In some embodiments, Fig. 9Two curved track grooves 15 are arranged at intervals on each single-sided rack 12. Each curved track groove 15 is respectively connected to two rolling bearings 14 on the lower base 11 in rolling manner. The single-sided rack 12 is stably connected through the rolling bearings 14, thereby improving the running stability of the single-sided rack 12.

[0032] In some embodiments, Fig. 9 The lower base 11 is symmetrically provided with an assembly seat 24 adapted to each rolling bearing 14. The rolling bearings 14 are correspondingly connected to the assembly seats 24 in rotation and are rollingly connected to the curved track groove 15. The rolling bearings 14 are installed on the assembly seats 24, which is convenient for disassembly and assembly, and is not easy to damage the lower base 11, thereby improving the service life of the entire device.

[0033] In some embodiments, Fig.10 The single-sided rack 12 includes a second tooth plate 25 and teeth arranged on one side of the second tooth plate 25. The second tooth plate 25 is provided with second reinforcing ribs 26 arranged in a cross pattern. The second reinforcing ribs 26 can strengthen the support strength of the single-sided rack 12, ensuring the stability and safety of the upper mounting system 1 and the cradle body.
