DETAILED DESCRIPTION

[0034] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments of the present application, and are not intended to limit the present application.

[0037] Reference Figures 1 to 11The utility model discloses a height adjustable infant and child care equipment, include: support base 1, electric swing mechanism 2, bearing frame 31, height adjusting mechanism 4, shell 5, control part, underframe 32. The infant and child care equipment can be specifically designed as infant and child rocking chair or infant and child bed etc. correspondingly, bearing frame 31 can be designed as the seat or bed body of receiving infant and child. In the embodiment, the infant and child care equipment is infant and child bed, and the bearing frame 31 is bed body.

[0038] In the embodiment, support base 1 is used to support on the ground, electric swing mechanism 2 is connected with support base 1, and support base 1 supports electric swing mechanism 2 to provide support force for electric swing mechanism 2. Shell 5 is connected on support base 1 and covers electric swing mechanism 2 to realize appearance, dustproof and waterproof. Bearing frame 31 is connected with electric swing mechanism 2, and electric swing mechanism 2 supports bearing frame 31 to provide support force for bearing frame 31. Control part is electrically connected with electric swing mechanism 2. Height adjusting mechanism 4 is arranged between bearing frame 31 and support base 1. Height adjusting mechanism 4 is used to adjust the relative height of bearing frame 31 and support base 1. Electric swing mechanism 2 drives bearing frame 31 to move up and down relative to support base 1. When control part controls electric swing mechanism 2 to stop moving, bearing frame 31 is stopped at any height in the preset height range.

[0039] Based on also including underframe 32, the underframe 32 is fixedly connected with the output end of electric swing mechanism 2. One end of height adjusting mechanism 4 is connected with underframe 32, and the other end of height adjusting mechanism 4 is connected with bearing frame 31. Height adjusting mechanism 4 is used to adjust the relative height of bearing frame 31 and underframe 32, and further adjust the relative height of bearing frame 31 and support base 1. Height adjusting mechanism 4 can be selected to have lifting rod structures with different height levels. In order to connect the stepless adjustment of height, the height adjustment range of electric swing mechanism 2 driving bearing frame 31 to move up and down needs to be greater than the height adjustment range of each level of height adjusting mechanism 4.

[0040] In the above scheme, the electric swing mechanism 2 has two functions, one is to drive the carrier 31 to swing, and the other is to enable the carrier 31 to produce stepless height adjustment in the driving range of the electric swing mechanism 2. Thus, the electric swing mechanism 2 realizes two functions, so that the cost is reduced, and the height adjustment mechanism 4 can adjust the relative height of the carrier 31 and the base frame 32, thereby adjusting the relative height of the carrier 31 and the support base 1. For example, the electric swing mechanism 2 drives the carrier 31 to move up and down relative to the support base 1 in a height range of H1, that is, the maximum range of the relative stepless height adjustment realized by the electric swing mechanism 2 is H1, and the maximum range of the relative height adjustment of the carrier 31 and the base frame 32 by the height adjustment mechanism 4 is H2. Therefore, in the baby care device of the present scheme, the total relative range of the stepless height adjustment of the carrier 31 relative to the support base 1 is H1+H2, so that the total adjustment range is increased, and the user can adjust as much as needed in the total adjustment range.

[0041] In daily use, the user sets an initial height for the carrier 31 by using the height adjustment mechanism 4, and the main frequently used height adjustment function is the stepless height adjustment function of the electric swing mechanism 2. When the initial height of the lifting needs to be changed, the height adjustment function of the height adjustment mechanism 4 is used. Therefore, the height adjustment mechanism 4 does not need to be frequently operated, and the cooperation of the height adjustment mechanism 4 can be set tightly, and even locked when not in use, thereby improving the support stability of the height adjustment mechanism 4, and the carrier 31 is not easy to shake. In the prior art, the frequently used height adjustment function is the function of the lifting rod, and the cooperation of the lifting rod needs to be set with sufficient gap, and cannot be locked, otherwise the adjustment operation will be inconvenient.

[0042] If only the stepless height adjustment function of the electric swing mechanism 2 is left, in order to meet the sufficient height adjustment range, the range of the stepless height adjustment of the electric swing mechanism 2 needs to be large, which leads to a long driving arm of the electric swing mechanism 2. In order to meet the swing, the electric swing mechanism 2 needs to be large, and a large power and large size motor needs to be selected, which leads to a large overall size and high cost of the electric swing mechanism 2. If a general size motor is selected, it will be not conducive to the swing of the electric swing mechanism 2, and will not save labor, and even the swing will not start.

[0043] Therefore, the baby care device of the present application can drive the carrier 31 to swing, and also realize stepless adjustment of a large overall height range by combining double height adjustment, meet the use requirements of different heights, has low cost, high support stability, is not easy to shake, and has high overall comprehensive performance.

[0044] For a more intuitive understanding, assuming that when the electric swing mechanism 2 drives the carrier frame 31 to be at the lowest position, the height adjustment mechanism 4 is in the retracted state, the height of the top of the carrier frame 31 relative to the ground is 680mm, H1 is 50mm, H2 is 100mm and is divided into four gears (each gear is 25mm), then the height of the top of the carrier frame 31 relative to the ground can be adjusted between 680mm and 830mm. For example, when the user needs to frequently adjust the height of the carrier frame 31 between 680mm and 730mm in daily use, the height adjustment mechanism 4 can be locked in the first gear (the lowest gear) for a long time, and only the electric swing mechanism 2 is used for frequent height adjustment; for example, when the user needs to frequently adjust the height of the carrier frame 31 between 730mm and 780mm in daily use, the height adjustment mechanism 4 can be locked in the third gear for a long time, and only the electric swing mechanism 2 is used for frequent height adjustment; for example, when the user needs to frequently adjust the height of the carrier frame 31 between 780mm and 830mm in daily use, the height adjustment mechanism 4 can be locked in the fourth gear (the highest gear) for a long time, and only the electric swing mechanism 2 is used for frequent height adjustment. It should be noted that the above parameters are only for convenience of description, and are not limiting.

[0045] Referring to Figure 1 and Figure 9 , in order to facilitate the height adjustment of the carrier frame 31 by the electric swing mechanism 2, the control part comprises a control panel 7 arranged on the shell 5, the control panel 7 is electrically connected with the electric swing mechanism 2, and the control panel 7 is provided with at least a position adjustment button for controlling the start and stop of the electric swing mechanism 2. When the electric swing mechanism 2 drives the carrier frame 31 to move to the target height position, the electric swing mechanism 2 can be stopped by triggering the position adjustment button, so that the carrier frame 31 is stopped at the target height position.

[0046] The baby care equipment of the utility model can trigger the position adjustment button to adjust the carrier frame 31 to the highest position by the electric swing mechanism 2 in an electric manner, without manual adjustment, which is convenient for the user to hold or place the baby, and does not hurt the user's waist; after placing the baby, the carrier frame 31 is adjusted to a suitable height to entertain and pacify the baby, or to facilitate the parent to take care of the baby at night.

[0047] Moreover, compared with the prior art, when the highest height of the bearing frame to the ground is set to the same height, because the height of H1 can be increased when the electric swing mechanism 2 drives the bearing frame 31 to stop at the highest position, the height of the bearing frame 31 of the utility model can be lower, thereby saving cost; from another angle, if the bearing frame 31 with the same height size is adopted, because the height of H1 can be increased when the electric swing mechanism 2 drives the bearing frame 31 to stop at the highest position, the highest height of the bearing frame 31 of the utility model will be higher than that of the prior art, and the user does not need to bend too much when holding or placing the baby, thereby protecting the user.

[0048] It should be noted that the control panel 7 can also be arranged on the support base 1 or the bottom frame 32 or the bearing frame 31, and the specific installation position of the control panel 7 is not limited here.

[0049] Referring to Figures 1 to 6 In the embodiment, the height adjusting mechanism 4 comprises at least two first lifting rod assemblies, the two first lifting rod assemblies are arranged at intervals to better support the bearing frame 31, the first lifting rod assembly comprises a first movable rod, a first fixed rod 41 and a first locking and unlocking mechanism 42, the first fixed rod 41 is fixedly connected with the bottom frame 32, the first movable rod is fixedly connected with the bearing frame 31, the first movable rod and the first fixed rod 41 are arranged in relative sliding mode and can be locked or unlocked relative to each other, and the first locking and unlocking mechanism 42 is used to lock or unlock the first movable rod and the first fixed rod 41 relative to each other. Of course, the first lifting rod assembly can also be provided with three, four or the like. Based on the aforementioned that the height of the bearing frame 31 is mainly adjusted frequently by the electric swing mechanism 2 in daily use, the first movable rod does not need to be adjusted frequently, and therefore the cooperation between the first movable rod and the first fixed rod 41 can be set to be tight without leaving a larger cooperation gap, and will not substantially affect the normal use of the user, and even can be locked after being adjusted to an applicable gear height in advance, and is unlocked when the first movable rod needs to be adjusted, and therefore the first movable rod is not prone to shaking relative to the first fixed rod 41, and the stability is high.

[0050] Referring to Figures 2 to 6In the embodiment, the bearing frame 31 comprises an upper surrounding rod 311, a lower surrounding rod 312, and at least two vertical rods 313, the two vertical rods 313 are arranged at intervals and are respectively connected between the upper surrounding rod 311 and the lower surrounding rod 312, the upper surrounding rod 311 functions as a guardrail, and the lower surrounding rod 312 is used to support the bottom plate of the seat pocket. In order to simplify the structure of the bearing frame 31, preferably, the vertical rod 313 is used as the first movable rod, and the vertical rod 313 is slidingly sleeved outside the first fixed rod 41. In this way, the vertical rod 313 in the bearing frame 31 is used as the first movable rod and is externally arranged on the first fixed rod 41, so that the connecting structure between the lower surrounding rod 312 and the vertical rod 313 is simplified, and no additional adapter is needed to bypass the first fixed rod 41, and the lower surrounding rod 312 can be directly connected to the lower end of the vertical rod 313, so that the structure of the bearing frame 31 is simplified, and the cost is reduced.

[0051] Referring to Figure 3 More preferably, when the vertical rod 313 slides to the lowest position relative to the first fixed rod 41, the bottom frame 32 is located on the inner side of the lower surrounding rod 312, and the supporting surface of the bottom frame 32 and the supporting surface of the lower surrounding rod 312 are correspondingly leveled, so that when the bearing frame 31 is at the lowest position relative to the bottom frame 32, the bottom frame 32 and the lower surrounding rod 312 of the bearing frame 31 can both support the bottom plate of the seat pocket, thereby improving the safety.

[0052] Referring to Figures 4 to 6In the embodiment, the first locking and unlocking mechanism 42 is arranged on the vertical rod 313, and the first locking and unlocking mechanism 42 can be lifted together with the bearing frame 31 relative to the base frame 32 and lock the bearing frame 31 at a preset height. Specifically, the first locking and unlocking mechanism 42 comprises a first bearing 421, a first switch 422, a first transmission member 423, a first lock block 424, a first elastic member 425, and a second elastic member 426. The first bearing 421 is arranged in the interior of the vertical rod 313, one end of the first bearing 421 is fixedly connected with the vertical rod 313, and the other end of the first bearing 421 is slidingly inserted into the interior of the first fixed rod 41. The first bearing 421 can be lifted together with the vertical rod 313 relative to the first fixed rod 41. The first switch 422 is movably arranged on the vertical rod 313, preferably slidingly arranged on the vertical rod 313. The first lock block 424 is movably arranged on the other end of the first bearing 421, preferably slidingly arranged on the other end of the first bearing 421. One end of the first transmission member 423 is connected with the first switch 422, and the other end of the first transmission member 423 is connected with the first lock block 424. A plurality of first lock holes 411 corresponding to different height levels are arranged on the first fixed rod 41, the first lock holes 411 are matched with the first lock block 424, and the first switch 422 drives the first lock block 424 to be inserted into or separated from the first lock holes 411 through the first transmission member 423. The first elastic member 425 is used for driving the first switch 422 to reset, and two ends of the first elastic member 425 are respectively connected with the first switch 422 and the vertical rod 313. The second elastic member 426 is used for driving the first lock block 424 to reset, and two ends of the second elastic member 426 are respectively connected with the first lock block 424 and the first bearing 421. The first elastic member 425 and the second elastic member 426 are preferably springs.

[0053] In other examples, the first switch 422 can also be movably arranged on one end of the first bearing 421, such as slidingly arranged or rotatably arranged, and the first switch 422 can drive the first transmission member 423 to make the first lock block 424 inserted into or separated from the first lock holes 411.

[0054] In the above scheme, the first bearing 421, the first fixed rod 41, and the vertical rod 313 are arranged in three layers from inside to outside, so that the first fixed rod 41 is clamped between the first bearing 421 and the vertical rod 313, which makes the cooperation of the vertical rod 313 and the first fixed rod 41 more compact and improves the stability and reduces the shaking.

[0055] Referring to Figures 6 to 8In the safety test standard of the European Union, it is required that the first switch 422 is not disengaged when pressed under a certain test force (for example, a force of 50 N). Based on this, in the present embodiment, the lower surface of the first locking block 424 is provided with a groove 4241 which is engaged with the lower edge of the first locking hole 411 under the action of gravity. In this way, when the first switch 422 is pressed under a test force, the engagement force of the groove 4241 and the first locking hole 411 needs to be overcome first, thereby avoiding the occurrence of disengagement when the first locking block 424 is disengaged from the first locking hole 411 during testing, thereby meeting the safety test requirements. Preferably, in order to avoid the first locking block 424 being stuck at the first locking hole 411 and being unable to disengage, the groove 4241 is arc-shaped, so that the groove 4241 can disengage from the first locking hole 411. In other examples, the groove 4241 can also be inverted V-shaped or the groove 4241 has a guide slope.

[0056] Based on the structure of the first locking and unlocking mechanism 42 described above, since the first carrier 421 is inserted into the first fixed rod 41, and the vertical rod 313 is slidingly sleeved outside the first fixed rod 41, it is relatively troublesome to install a conventional pull rope as the first driving member 423.
