Common baby care equipment includes baby dining chair, baby rocking chair and baby bed, etc., which are more and more popular with consumers in the market, and consumers also put forward more requirements for baby care equipment. Baby care equipment is a relatively large product, in order to facilitate transportation, baby care equipment needs to be disassembled or folded to reduce its volume during transportation, and in order to realize the lifting of baby care equipment, lifting mechanism is needed to support.

[0003] In the existing liftable baby care equipment, single lifting mechanism is used to support the seat frame (such as Chinese patent 202210629642.2), however, when single lifting mechanism is used for support, the performance requirements of the lifting mechanism itself, such as strength, connection strength and torsional strength, are relatively high, such as generally using high-performance air pressure rod and other components, which will cause the overall cost to be higher. There are also multiple lifting mechanisms to support the seat frame, such as four lifting rod assemblies to support the four corners around the seat frame (such as Chinese patent CN201610718331.8), or two lifting rod assemblies arranged at a large distance along the length direction of the seat frame to support the bottom of the seat frame (such as Chinese patent CN202020532632.3, two lifting rod assemblies have good stability), however, due to the distance between the lifting rod assemblies is far apart, if each lifting rod assembly is separately detachable with the seat frame and the supporting leg, it will make the support stability of the lifting rod assembly decrease after disassembly and transportation, and it is easy to shake, if you want to ensure the stability after assembly, you need to strengthen the structure of the lifting rod assembly itself and the disassembly point, which will increase the cost; if the lifting rod assembly is set in a non-detachable way, due to the distance between the lifting rod assemblies is far apart, it will lead to the overall packaging of the baby care equipment to be large, even if the seat frame and the supporting leg are folded or contracted, the reduction of the overall volume is extremely limited, which is not convenient for transportation; moreover, the lifting rod assemblies are exposed, which is not beautiful.

The two lifting rod assemblies 4 support the seat frame 6 through the connecting device 5, the lifting rod assembly 4 comprises a movable rod 41, a fixed rod 42 and a second locking and unlocking mechanism 43, the movable rod 41 and the fixed rod 42 are relatively slidably arranged and can be locked or unlocked, wherein the fixed rods 42 of the two lifting rod assemblies 4 are fixedly connected with the base 2, the movable rods 41 of the two lifting rod assemblies 4 are fixedly connected with the connecting device 5, the connecting device 5 is connected with the seat frame 6, and the seat frame 6 can be folded or can be retracted or can be detached from the connecting device 5, and in the embodiment, the seat frame 6 is preferably detachably connected with the connecting device 5, so that the seat frame 6 can be detached from the connecting device 5 during transportation, thereby reducing the volume during transportation. The shell 3 comprises a movable shell 31 and a fixed shell 32 which are sleeved, the movable shell 31 and the fixed shell 32 form a containing cavity, the movable shell 31 is fixedly arranged relative to the connecting device 5, the fixed shell 32 is fixedly arranged relative to the base 2, and the two lifting rod assemblies 4 and at least part of the connecting device 5 are located in the containing cavity.

[0149] It should be noted that the number of support feet 1 can also be one, two, three, five, etc., and the number of support feet 1 is not limited in the embodiment. When the number of support feet 1 is one or two, the structure of the support feet 1 needs to be changed accordingly to meet the support requirements (at this time, the support feet 1 cannot adopt the shape as shown in the embodiment), since the utility model concept of the utility model does not lie in the shape of the support feet 1, therefore, it is not additionally illustrated and stated here.

[0150] It should be noted that the number of lifting rod assemblies 4 can also be three, four, etc., and the number of lifting rod assemblies 4 is not limited in the embodiment, and the number of lifting rod assemblies 4 can meet two or more. In this way, at least two lifting rod assemblies 4 are used to provide lifting support for the seat frame 6, which is conducive to reducing the performance requirements of the lifting rod assemblies 4 under the condition of ensuring the stability of the support, thereby reducing the overall cost of the lifting structure.

[0151] The utility model provides a baby care equipment, support foot 1 supports base 2, base 2 supports lifting rod subassembly 4, lifting rod subassembly 4 supports seat frame 6 through connecting device 5, need to adjust seat frame 6 height, after unlocking the movable rod 41 with fixed rod 42, make seat frame 6 lift or press down to adjust height, in the process of adjusting height, support foot 1, base 2, fixed rod 42, fixed shell 32 keep unmoved together, movable rod 41, connecting device 5, seat frame 6, movable shell 31 lift together, need to transport, can be separated from base 2, seat frame 6 can be separated from connecting device 5, keep base 2, shell 3, two lifting rod subassembly 4, connecting device 5 as a modular unit, can pack and transport support foot 1, seat frame 6, modular unit respectively.

[0152] According to need, optional seat frame 6 itself can further contract or fold or disassemble, to further reduce the volume, the specific structure of seat frame 6 is not limited in the embodiment, and the utility model concept of the utility model is not in the specific structure of seat frame 6, so it is not stated here, seat frame 6 can adopt any structure.

[0153] Thus, the baby care equipment, the relative fixed connection of the fixed rod 42 in the multiple lifting rod subassembly 4 is realized through the base 2, the relative fixed connection of the movable rod 41 in the multiple lifting rod subassembly 4 is realized through the connecting device 5, and the lifting rod subassembly 4 and at least part of the connecting device 5 are covered in the containing cavity by the movable shell 31 and the fixed shell 32 that can be nested, to form a modular unit, which will not be exposed when the lifting rod subassembly 4 is lifted, and the volume of the modular unit can be very small, beautiful and low in cost, and then the support foot 1 is connected with the base 2, and the seat frame 6 is connected with the connecting device 5, wherein the support foot 1 can be folded or contracted or detached from the base 2, and the seat frame 6 can be folded or contracted or detached from the connecting device 5, when transporting, the lifting rod subassembly 4 does not need to be detached, and only the support foot 1 needs to be detached from the base 2 and the seat frame 6 needs to be detached from the connecting device 5, to ensure that the support stability provided by the lifting rod subassembly 4 is high and not easy to shake when the baby care equipment is normally used, and the overall volume of the baby care equipment can be greatly reduced when transporting, greatly improving the overall comprehensive performance of the baby care equipment.

[0154] Need to be explained, when the support foot 1 adopts a foldable or contractible structure, and the seat frame 6 adopts a foldable or contractible structure, the size of the volume reduced by the support foot 1 and the seat frame 6 is easily affected by the above-mentioned modular unit when transporting, because the volume of the modular unit can be very small, and the overall volume can be greatly reduced after folding or contracting the seat frame 6 and the support foot 1, which can also facilitate transportation.

[0155] Of course, other ways can also be used to reduce the space occupied by the seat frame 6 and the support feet 1 during transportation, so as to reduce the overall volume of the baby care device for transportation.

When the baby lies on the baby care device, it may deviate from the center position of the seat frame 6 due to turning over and other conditions, which will cause the load center of gravity to deviate. The two lifting rod assemblies 4 arranged diagonally can provide support on both sides along the length direction of the seat frame 6, and also provide support on both sides along the width direction of the seat frame 6. Compared with the arrangement along the length or width direction of the seat frame 6, the two lifting rod assemblies 4 arranged in this way are better and more stable in stress under the condition of ensuring the low overall cost of the lifting mechanism.

[0157] It should be noted that the seat frame 6 of the embodiment is preferably rectangular, and of course, the seat frame 6 can also be oval or the two ends of the seat frame 6 can be arc-shaped. The seat frame 6 also has a length direction and a width direction.

[0169] More preferably, based on the foregoing driving mechanism 53, the limiting slot 5314 is movably arranged relative to the connecting portion 51, specifically, the limiting slot 5314 is hinged above the connecting seat 5123, and further comprises a swing mode adjusting mechanism 9 used to adjust the position of the limiting slot 5314, so that the swing mode adjusting mechanism 9 can be used to realize multiple swing modes of the baby care device when used as a cradle.

[0170] Referring to Figures 12 to 14As a specific example, the swing mode adjusting mechanism 9 comprises a connecting handle 91, a first switch assembly 92, a first transmission member 93, and a first locking and unlocking part 97. The lower end of the connecting handle 91 is connected with the limiting groove 5314, the first switch assembly 92 is connected with the upper end of the connecting handle 91 and is located at the upper end of the movable shell 31. Thus, the first switch assembly 92 can be located at a relatively high position by the action of the connecting handle 91, in particular, the first switch assembly 92 can be located at the upper end of the movable shell 31, so that the first switch assembly 92 does not interfere with the fixed shell 32 and does not affect the lifting stroke of the seat frame 6, and the seat frame 6 can be designed to be lower. The first locking and unlocking part 97 is arranged between the limiting groove 5314 and the connecting part 51, and the first transmission member 93 is connected with the first switch assembly 92 and the first locking and unlocking part 97 respectively.

[0171] Specifically, the first locking and unlocking part 97 comprises a locking member 94, a plurality of second locking grooves 95 arranged on the connecting part 51, and a third reset member 96. The locking member 94 is movably connected with the limiting groove 5314 or the connecting handle 91, the first transmission member 93 is connected between the first switch assembly 92 and the locking member 94, and the locking member 94 can be locked with different second locking grooves 95 to correspond to the different positions of the limiting groove 5314. The third reset member 96 is arranged between the locking member 94 and the limiting groove 5314 or between the locking member 94 and the connecting handle 91. The third reset member 96 drives the locking member 94 to reset so that the locking member 94 is locked with the corresponding second locking groove 95.

[0172] Of course, in other embodiments, the first locking and unlocking part 97 can not be provided with a reset member, but a reset member can be arranged in the first switch assembly 92 to indirectly drive the locking member 94 to reset.

[0173] In the embodiment, preferably, the first switch assembly 92 is movably connected with the upper end of the connecting handle 91, and the first switch assembly 92 is also movably connected with the connecting part 51. After the first switch assembly 92 drives the first locking and unlocking part 97 to complete unlocking through the first transmission member 93, the first switch assembly 92 can be moved relative to the connecting part 51, so that the first switch assembly 92 drives the connecting handle 91, and the connecting handle 91 drives the limiting groove 5314 to move relative to the connecting part 51, thereby adjusting the position of the limiting groove 5314. Preferably, the first switch assembly 92 is slidingly connected with the connecting part 51, the first switch assembly 92 is hinged to the upper end of the connecting handle 91, and the first switch assembly 92 can also move a distance (such as linear sliding or arc sliding) relative to the upper end of the connecting handle 91, and the limiting groove 5314 rotates relative to the connecting part 51. Thus, the sliding action of the first switch assembly 92 can be converted into the rotating action of the connecting handle 91, so that the connecting handle 91 drives the limiting groove 5314 to rotate and adjusts the position of the limiting groove 5314.

[0174] Specifically, the connecting part 51 comprises a switch box 5111, and the switch box 5111 is arranged on the first connecting piece 511. The first switch assembly 92 comprises a switch connecting piece 921, a shaft sleeve 922, an adapter 923 and a first switch 924. The adapter 923 is hingedly connected to the upper end of the connecting handle 91. The shaft sleeve 922 relatively limits the adapter 923 and the connecting handle 91 to avoid loosening between the adapter 923 and the connecting handle 91. The adapter 923 is also in sliding connection with the switch connecting piece 921. The switch connecting piece 921 is in sliding connection with the switch box 5111. The first switch 924 is hingedly connected to the switch connecting piece 921. The first switch 924 is connected with the first transmission member 93. The upper end of the movable shell 31 is provided with an avoiding groove 315 for exposing the first switch 924. The first transmission member 93 is preferably a cable. One end of the first switch 924 is connected with the first transmission member 93. One end of the lock catch 94 is hingedly connected below the limiting groove 5314. The other end of the lock catch 94 is connected with the other end of the first transmission member 93. The third reset member 96 is preferably a spring.

A plurality of second lock grooves 95 are arranged along the circular arc of the rotating shaft 5312 between the limiting groove 5314 and the connecting seat 5123. When it is needed to adjust the position of the limiting groove 5314, the first switch 924 is rotated. The first switch 924 drives the lock catch 94 to rotate upward through the first transmission member 93, so that the lock catch 94 compresses the third reset member 96 and the lock catch 94 is separated from the corresponding second lock groove 95 to complete unlocking. Then the first switch 924 is pushed. The first switch 924 drives the switch connecting piece 921 to slide relative to the switch box 5111. The switch connecting piece 921 drives the connecting handle 91 through the adapter 923. The connecting handle 91 and the adapter 923 relatively rotate, and the adapter 923 and the switch connecting piece 921 relatively slide, so that the connecting handle 91 drives the limiting groove 5314 to rotate relative to the connecting seat 5123 until the lock catch 94 is aligned with the second lock groove 95 of the new target. Then the first switch 924 is released. The lock catch 94 is inserted into the second lock groove 95 to complete locking under the driving of the third reset member 96. Because the connecting handle 91 and the adapter 923 relatively rotate, and the adapter 923 and the switch connecting piece 921 relatively slide, it can be avoided that the first switch assembly 92 and the connecting handle 91 interfere with each other during adjustment.

[0175] Referring to Figure 3 , Figures 5 to 7, based on the driving mechanism 53 can drive the seat frame 6 activity, in order to make the seat frame 6 has the active state and the fixed state, preferably, also includes the first locking and unlocking mechanism 8, the first locking and unlocking mechanism 8 is used for locking or unlocking between the mounting seat 52 and the connecting portion 51, the first locking and unlocking mechanism 8 locks the mounting seat 52 and the connecting portion 51 when preventing the driving mechanism 53 from driving the seat frame 6 to move, in this way, further increase the function of the product, so that the cost performance is higher, consumers like it more.

[0176] As a specific example, the first locking and unlocking mechanism 8 includes a first rotating piece 81, a first lock block 82, a first reset piece 83, the first rotating piece 81 is pivoted to the mounting seat 52, further comprising a plug 84 and a fourth slot 85 which are inserted together, the first rotating piece 81 is provided with the plug 84, the connecting portion 51 is provided with the fourth slot 85, the first lock block 82 is movably arranged on the first rotating piece 81, the first reset piece 83 is arranged between the first rotating piece 81 and the first lock block 82, further comprising a first lock tongue 86 and a first lock slot 87 which are inserted together, the first lock block 82 is provided with the first lock tongue 86, the connecting portion 51 is provided with the first lock slot 87, the first lock tongue 86 and the first lock slot 87 are inserted together to limit the plug 84 in the fourth slot 85, so as to prevent the driving mechanism 53 from driving the seat frame 6 to move. Specifically, the fourth slot 85 and the first lock slot 87 are arranged on the upper surface of the first connecting piece 511, the first rotating piece 81 and the mounting seat 52 can generate pre-tightening force by increasing the rubber pad or interference fit, so that the first rotating piece 81 and the mounting seat 52 can be positioned relative to each other after rotating the first rotating piece 81 by applying external force, or a torsional spring or the like can be arranged between the first rotating piece 81 and the mounting seat 52 to make the first rotating piece 81 rotate upwardly and reset; the first lock block 82 is slidably arranged on the first rotating piece 81, the two first lock blocks 82 are connected by a cross bar, the first lock slot 87 is located on the inner side wall of the fourth slot 85, the first reset piece 83 is preferably a spring, during the process of rotating the first rotating piece 81 downwardly to insert the plug 84 into the fourth slot 85, the fourth slot 85 can push the first lock tongue 86 to make the first lock block 82 slide and compress the first reset piece 83, of course, the cross bar can also be manually driven to slide the first lock block 82 and compress the first reset piece 83, until the first lock tongue 86 and the first lock slot 87 are aligned, the first lock tongue 86 can be inserted into the first lock slot 87 under the action of the first reset piece 83, so as to limit the plug 84 in the fourth slot 85, thereby preventing the driving mechanism 53 from driving the seat frame 6 to move.

[0177] Of course, the setting objects of the plug 84 and the fourth slot 85 can also be interchangeable, that is, the plug 84 can be arranged on the connecting portion 51, and the fourth slot 85 is correspondingly arranged on the first rotating piece 81; similarly, the setting objects of the first lock tongue 86 and the first lock slot 87 can also be interchangeable, that is, the first lock tongue 86 can be arranged on the connecting portion 51, and the first lock slot 87 is correspondingly arranged on the first lock block 82.

[0178] Referring to Figure 8 , Figure 10 , Figure 11 and Figure 14 In the embodiment, the reinforcing mechanism 7 located in the accommodating cavity is further included, the reinforcing mechanism 7 is connected to the connecting device 5, the reinforcing mechanism 7 can ascend and descend with the connecting device 5, and the reinforcing mechanism 7 can be used for supporting the inner side wall of the movable shell 31 or the inner side wall of the fixed shell 32. In this way, the reinforcing mechanism 7 has the effect of providing support for the shell 3, so as to avoid deformation of the shell 3 caused by lateral impact or extrusion during transportation.

[0179] It can be understood that the reinforcing mechanism 7 can directly support the inner side wall of the movable shell 31 or the inner side wall of the fixed shell 32; or when a small amount of deformation of the shell 3 is caused by impact or extrusion and the like, the reinforcing mechanism 7 supports the inner side wall of the movable shell 31 or the inner side wall of the fixed shell 32, that is, the reinforcing mechanism 7 can have a certain gap with the inner side wall of the movable shell 31 or the inner side wall of the fixed shell 32, the gap is eliminated when a small amount of deformation of the shell 3 is eliminated, so that the reinforcing mechanism 7 forms a supporting effect.

[0180] Specifically, the reinforcing mechanism 7 includes a reinforcing sleeve 71, the reinforcing sleeve 71 is connected to the connecting device 5, and the circumferential side wall of the reinforcing sleeve 71 can be used for sliding against the inner side wall of the movable shell 31 or the circumferential side wall of the reinforcing sleeve 71 can be used for sliding against the inner side wall of the fixed shell 32. During installation, the reinforcing sleeve 71 can be located at the lower opening end of the movable shell 31 or the reinforcing sleeve 71 can be located at the upper opening end of the fixed shell 32, so as to provide more comprehensive support for the shell 3 by using the reinforcing sleeve 71. Similarly, the circumferential side wall of the reinforcing sleeve 71 can directly abut against the inner side wall of the movable shell 31 or the circumferential side wall of the reinforcing sleeve 71 can directly abut against the inner side wall of the fixed shell 32, so as to form direct support; or the circumferential side wall of the reinforcing sleeve 71 can have an eliminable gap with the inner side wall of the movable shell 31 or the circumferential side wall of the reinforcing sleeve 71 can have an eliminable gap with the inner side wall of the fixed shell 32, so as to form support after a small amount of deformation of the shell 3.

[0181] For the convenience of understanding, in the embodiment, preferably, the movable shell 31 is sleeved outside the fixed shell 32, so that water or dust and the like cannot enter the accommodating cavity from the gap between the movable shell 31 and the fixed shell 32. At this time, the circumferential side wall of the reinforcing sleeve 71 will slide against the inner side wall of the fixed shell 32. The reinforcing sleeve 71 first provides a supporting force acting on the fixed shell 32, and then indirectly provides a supporting force acting on the movable shell 31 by using the fixed shell 32, so as to form the overall support of the outer shell 3.

[0182] Of course, in other examples, when the fixed shell 32 is sleeved outside the movable shell 31, correspondingly, the circumferential side wall of the reinforcing sleeve 71 will slide against the inner side wall of the movable shell 31. The reinforcing sleeve 71 first provides a supporting force acting on the movable shell 31, and then indirectly provides a supporting force acting on the fixed shell 32 by using the movable shell 31, so as to form the overall support of the outer shell 3.

[0183] Preferably, the reinforcing sleeve 71 is provided with a second through hole 711 for the fixed rod 42 and / or the movable rod 41 to pass through. In this way, the reinforcing sleeve 71 can use the fixed rod 42 or the movable rod 41 to make the reinforcing sleeve 71 not easy to deform and have a better supporting effect. At the same time, the reinforcing sleeve 71 can also reversely limit the torsion of the fixed rod 42 or the movable rod 41, so that the seat frame 6 is more stable.

[0184] Further preferably, in order to make the seat frame 6 be able to descend lower, the reinforcing sleeve 71 is slidably arranged in the connecting device 5 according to a preset stroke. The reinforcing mechanism 7 further comprises a second reset member 72 connected between the reinforcing sleeve 71 and the connecting device 5. When the reinforcing sleeve 71 descends to the lower position with the connecting device 5 and abuts against the base 2, the base 2 can push the reinforcing sleeve 71 to compress the second reset member 72. That is, the reinforcing sleeve 71 has an upper stroke point and a lower stroke point relative to the connecting device 5. The size of the preset stroke is determined according to needs. The second reset member 72 can keep the reinforcing sleeve 71 at the lower stroke point. When the seat frame 6 is raised to the highest position, the circumferential side wall of the reinforcing sleeve 71 can also well abut against the inner side wall at the open end of the fixed shell 32, without the need to intentionally heighten the fixed shell 32. If the fixed shell 32 is heightened, since the movable shell 31 is sleeved outside the fixed shell 32, it will affect the seat frame 6 to be unable to descend lower. When the seat frame 6 is lowered to the lowest position, the base 2 can push the reinforcing sleeve 71 to slide upward relative to the connecting device 5 to compress the second reset member 72. The reinforcing sleeve 71 will not hinder the descent of the seat frame 6. In this way, under the condition of ensuring the supporting effect of the reinforcing sleeve 71 on the outer shell 3, the seat frame 6 can descend lower, satisfying more use requirements of consumers.

[0185] Specifically, based on the structure of the connecting device 5, the connecting portion 51 further comprises a connecting plate 518 and a fixing sleeve 519, wherein the connecting plate 518 is connected below the connecting seat 5123 in the first connecting piece 511, the fixing sleeve 519 is connected below the connecting plate 518, the reinforcing sleeve 71 is sleeved outside the fixing sleeve 519, the reinforcing sleeve 71 can slide up and down relative to the fixing sleeve 519, and a limiting structure such as a stepped structure or a limiting block can be further arranged between the reinforcing sleeve 71 and the fixing sleeve 519 to limit the reinforcing sleeve 71 from being separated from the fixing sleeve 519, and the second reset piece 72 is preferably a spring, the upper end of the second reset piece 72 abuts against the lower side of the connecting plate 518, and the upper end of the second reset piece 72 abuts against the upper side of the reinforcing sleeve 71.

[0186] Referring to Figure 5 , Figure 8 , Figures 15 to 22 In the embodiment, the second locking and unlocking mechanism 43 comprises a second locking and unlocking portion 431, a second transmission member 432 and a second switch assembly 433, the second locking and unlocking portion 431 is arranged between the movable rod 41 and the fixed rod 42, one end of the second transmission member 432 is connected with the second locking and unlocking portion 431, the other end of the second transmission member 432 is connected with the second switch assembly 433, and the second switch assembly 433 is arranged on the connecting device 5. Specifically, the second switch assembly 433 of one of the lifting rod assemblies 4 is arranged on the first connecting piece 511, and the second switch assembly 433 of the other lifting rod assembly 4 is arranged on the second connecting piece 512. Compared with arranging the second switch assembly 433 on the shell 3, arranging and bearing the second switch assembly 433 by means of the connecting device 5 (specifically the first connecting piece 511 or the second connecting piece 512) can make the position of the second switch assembly 433 higher, so as not to affect the lifting of the lifting rod assembly and make the seat frame lower. Compared with arranging the second switch assembly 433 on the seat frame 6, the cost of the present application is lower and the appearance is more beautiful. Preferably, the second transmission member 432 is a cable.

[0187] Referring to Figure 18 and Figure 19For example, the second switch assembly 433 is arranged on the first connecting piece 511, as a specific example, the second switch assembly 433 includes a protective handle 4331, a second switch 4332, a first sliding block 4333, a second sliding block 4334, a fifth reset piece 4335, the first connecting piece 511 is provided with a first sliding groove 514 for sliding cooperation with the first sliding block 4333, a second sliding groove 515 for sliding cooperation with the second sliding block 4334, and a containing groove 516 for accommodating the rotation and folding of the protective handle 4331, the protective handle 4331 and the second switch 4332 are coaxially arranged in the containing groove 516 around the rotating shaft 517 on the first connecting piece 511, the fifth reset piece 4335 is arranged between the protective handle 4331 and the second switch 4332, the second switch 4332 can be used to drive the first sliding block 4333 to slide, the first sliding block 4333 can be used to drive the second sliding block 4334 to slide, the second sliding block 4334 is connected with the other end of the second transmission member 432, the protective handle 4331 has an open state and a folding state; when the protective handle 4331 is in the open state, the protective handle 4331 drives the second switch 4332 to rotate outwardly and expose, at this time, the second switch 4332 can be operated and drive the second lock unlocking part 431 through the second transmission member 432, so that the second lock unlocking part 431 releases the locking of the movable rod 41 and the fixed rod 42; when the protective handle 4331 is in the folding state, the protective handle 4331 drives the second switch 4332 to rotate inwardly and hide, thereby preventing the second switch 4332 from being operated, so that the second lock unlocking part 431 keeps the movable rod 41 and the fixed rod 42 locked and cannot be lifted. In this way, when the protective handle 4331 is folded, the second switch 4332 can be hidden in the containing groove 516, reducing the occupied packaging space, making the volume smaller after packaging, and the appearance is beautiful.

[0188] Specifically, the protective handle 4331 is provided with an abutting groove 43311, the second switch 4332 is provided with a spring abutting piece 43321 and a first pushing block 43322, the first sliding block 4333 is provided with a second pushing block 43331 and a second inclined groove 43332, the second sliding block 4334 is provided with a second protrusion 43341, and the fifth reset member 4335 is preferably a spring, one end of the fifth reset member 4335 abuts against the front side wall of the abutting groove 43311, the spring abutting piece 43321 is located in the abutting groove 43311 and can relatively rotate in the abutting groove 43311, the rear side wall of the abutting groove 43311 can abut against the spring abutting piece 43321, so that when the protective handle 4331 is rotated outward to be opened, the second switch 4332 can be driven to rotate outward to be exposed through the cooperation of the abutting groove 43311 and the spring abutting piece 43321, the second protrusion 43341 is inserted into the second inclined groove 43332 and can slide on the second inclined groove 43332, and the first pushing block 43322 can abut against the second pushing block 43331 to make the first sliding block 4333 slide when the second switch 4332 meets a certain angle of rotation (the specific condition is that after the protective handle 4331 drives the second switch 4332 to rotate outward to be exposed, the second switch 4332 is pressed to rotate), the first sliding block 4333 can drive the second sliding block 4334 to slide through the cooperation of the first sliding block 4333 and the second inclined groove 43332, and then the second sliding block 4334 drives the second transmission member 432, the second transmission member 432 acts on the second locking and unlocking part 431, so that the movable rod 41 and the fixed rod 42 are unlocked.

[0189] In combination Figures 20 to 22 In order to facilitate understanding, the specific operation process of the second switch assembly 433 is as follows: Figure 20 The protective handle 4331 is in the folded state, and the protective handle 4331 is first rotated to enter the opened state from the folded state, in this process, the rear side wall of the abutting groove 43311 abuts against the spring abutting piece 43321, so that the second switch 4332 can rotate together with the protective handle 4331, the second switch 4332 rotates outward to be exposed, although the first pushing block 43322 rotates together with the second switch 4332, the first pushing block 43322 has not abutted against the second pushing block 43331, that is, the first sliding block 4333 and the second sliding block 4334 remain unchanged, and the protective handle 4331 is in the opened state. Figure 21The shown protective handle 4331 is in the open state, and the second switch 4332 is exposed, so the second switch 4332 can be pressed. During the pressing of the second switch 4332, the second switch 4332 rotates to compress the fifth reset member 4335, and the first push block 43322 gradually starts to push the second push block 43331, so that the first sliding block 4333 slides, and the second sliding block 4334 slides under the cooperation of the second convex and the second inclined groove 43332, and drives the second locking and unlocking part 431 to unlock the movable rod 41 and the fixed rod 42 through the second transmission member 432, and the unlocking is completed, and the second lifting rod assembly 4 is in the unlocked state Figure 22 The shown second switch 4332 is pressed.

[0190] It can be understood that, in order to install and carry the second switch assembly 433 of the second lifting rod assembly 4, the second connecting member 512 will also be provided with the first sliding groove 514, the second sliding groove 515, and the accommodating groove 516. The specific installation mode and switch action of the second switch assembly 433 on the second connecting member 512 can be referred to the foregoing description, which will not be repeated here.

[0191] Of course, in other examples, the driving cooperation between the second switch 4332 and the second transmission member 432 can also adopt other modes, such as: there is no first sliding block 4333 and second sliding block 4334, and the other end of the second transmission member 432 is connected with the second switch 4332. When the second switch 4332 is pressed to rotate the second switch 4332 relative to the protective handle 4331, the second switch 4332 applies a pulling force to the second transmission member 432, so as to drive the second locking and unlocking part 431 to unlock the movable rod 41 and the fixed rod 42 through the second transmission member 432, and complete the unlocking. The pull rope protection sleeve of the second transmission member 432 at this time can be installed on the protective handle 4331, so that when the protective handle 4331 is rotated with the second switch 4332 to open or fold (i.e. without pressing the second switch 4332 to rotate the second switch 4332 relative to the protective handle 4331), no pulling force is generated on the second transmission member 432; or, there is the first sliding block 4333 but no second sliding block 4334. At this time, the first sliding block 4333 is connected with the other end of the second transmission member 432. When the second switch 4332 is pressed to rotate the second switch 4332 relative to the protective handle 4331, the second switch 4332 drives the first sliding block 4333 to slide, and the first sliding block 4333 applies a pulling force to the second transmission member 432, so as to drive the second locking and unlocking part 431 to unlock the movable rod 41 and the fixed rod 42 through the second transmission member 432, and complete the unlocking.

[0192] In comparison, the first slider 4333 and the second slider 4334 are adopted in the embodiment, and the second transmission member 432 does not need to be moved during the rotation of the protective handle 4331, the arrangement of the second transmission member 432 is simple, the bending and friction are reduced, and the opening and closing operation is smooth.

[0193] It should be noted that the specific structure of the second locking and unlocking part 431 is not limited, and any structure capable of locking or unlocking the movable rod 41 and the fixed rod 42 can be adopted. In order to facilitate understanding, the second locking and unlocking part 431 can adopt the following structure:

[0194] Referring to Figures 15 to 17 , the lower end of the movable rod 41 is provided with a lower block 411, the upper end of the fixed rod 42 is provided with an upper block 421, the lower block 411 is slidably arranged in the fixed rod 42, and the upper block 421 can be used to limit the lower block 411 from being separated from the fixed rod 42. A plurality of first lock holes 422 arranged in the vertical direction are further arranged on the side wall of the fixed rod 42. The second locking and unlocking part 431 comprises a lifting lock block 4311, a lifting sliding block 4312, and a fourth reset member 4313. The lifting lock block 4311 is horizontally slidably arranged on the lower block 411, and the lifting lock block 4311 can be inserted and matched with the first lock hole 422. The lifting sliding block 4312 is vertically slidably arranged on the lower block 411. A first protrusion 43111 is arranged on one side of the lifting lock block 4311, and a first inclined groove 43121 is arranged on the lifting sliding block 4312. The first protrusion 43111 and the first inclined groove 43121 are matched. The fourth reset member 4313 is preferably a spring and is arranged between the lower block 411 and the lifting sliding block 4312. The lifting sliding block 4312 is connected with the second transmission member 432. When the second switch assembly 433 is operated, the second switch assembly 433 drives the lifting sliding block 4312 to slide upward through the second transmission member 432. The lifting sliding block 4312 compresses the fourth reset member 4313, and the lifting sliding block 4312 drives the lifting lock block 4311 to slide under the cooperation of the first protrusion 43111 and the first inclined groove 43121, so that the lifting lock block 4311 is separated from the first lock hole 422 to complete the unlocking. At this time, the movable rod 41 can be lifted relative to the fixed rod 42. When the second switch assembly 433 is released, the lifting sliding block 4312 slides downward under the elastic force of the fourth reset member 4313 and resets, and the lifting sliding block 4312 drives the lifting lock block 4311 to slide reversely under the cooperation of the first protrusion 43111 and the first inclined groove 43121, so that the lifting lock block 4311 is inserted into the first lock hole 422 to complete the locking.

[0195] Referring to Figure 3 and Figure 4In order to facilitate the assembly of the movable shell 31, preferably, the movable shell 31 comprises a cylindrical shell 311 penetrating from top to bottom, a left upper cover 312 and a right upper cover 313. When assembling the modular unit, the shell 3 can be placed for final assembly. The cylindrical shell 311 can be installed from bottom to top and connected to the connecting portion 51, and then the left upper cover 312 and the right upper cover 313 are respectively installed horizontally to the cylindrical shell 311 and formed into fixed connection (which can be through screwing or buckling or locking or the like), so as to avoid interference between the movable shell 31 and the mounting seat 52 when assembling the movable shell 31, and also facilitate the design of various avoiding spaces on the movable shell 31. For example, the top of the movable shell 31 can be provided with an arc-shaped through hole 314, which can be specifically surrounded by the left upper cover 312 and the right upper cover 313, and the arc-shaped through hole 314 is provided for the rotating shaft 5312 to pass out and provide swing avoiding space for the rotating shaft 5312; for example, the circumferential outer side of the movable shell 31 can be provided with a through slot for avoiding the protective handle 4331, which can be specifically surrounded by the cylindrical shell 311, the left upper cover 312 and the right upper cover 313; for example, the left upper cover 312 is provided with an avoiding slot 315.

[0199] Thus, the present embodiment can also solve the same technical problems and achieve the same technical effects as shown in the embodiment 1.

[0200] In order to save space, the same technical features of the present embodiment as the embodiment 1 will not be repeated below, and only the different parts will be described.

[0201] Referring to Figures 26 to 31 In the present embodiment, in order to realize the detachable connection of the seat frame 6 and the mounting seat 52, as a preferred solution, the mounting seat 52 is provided with a first sliding insertion part 522, and the seat frame 6 is provided with a second sliding insertion part 611, and the first sliding insertion part 522 and the second sliding insertion part 611 can be inserted and matched.

[0203] Also refer to Figures 26 to 31 In the embodiment, a third locking and unlocking mechanism 100 is further included, which is used for locking or unlocking between the seat frame 6 and the mounting seat 52. Preferably, the third locking and unlocking mechanism 100 includes a second lock block 101, a third lock block 102, a linkage block 103, and a third switch 104, the second lock block 101, the third lock block 102, and the linkage block 103 are all movably arranged on the mounting seat 52, the second lock block 101, the third lock block 102, and the linkage block 103 are in linkage cooperation, the third switch 104 is arranged on the seat frame 6, and the seat frame 6 is further provided with a second lock hole 612 matched with the second lock block 101 and a third lock hole 613 matched with the third lock block 102, specifically, the third switch 104, the second lock hole 612, and the third lock hole 613 are all arranged on the bottom connecting plate 61, the third switch 104 can drive the second lock block 101 to be separated from the second lock hole 612, and at the same time, the second lock block 101 drives the third lock block 102 to be separated from the third lock hole 613 through the linkage block 103, thereby completing the unlocking between the seat frame 6 and the mounting seat 52. In this way, the locking or unlocking between the seat frame 6 and the mounting seat 52 is realized by the mode of driving double lock blocks through one switch, which is simple to operate and high in safety.

[0204] Specifically, the linkage block 103 is slidably arranged in the mounting seat 52 along a first direction, the second locking block 101 and the third locking block 102 are both slidably arranged in the mounting seat 52 along a second direction, the first direction and the second direction are perpendicular to each other, the first direction can be specifically the length direction of the seat frame 6, the second direction can be specifically the width direction of the seat frame 6, the linkage block 103 is provided with a first linkage inclined slot 1031 and a second linkage inclined slot 1032, the second locking block 101 is provided with a first protruding column 1011 which can slide in the first linkage inclined slot 1031, the third locking block 102 is provided with a second protruding column 1021 which can slide in the second linkage inclined slot 1032, and the sixth reset member 105 is arranged between the linkage block 103 and the mounting seat 52, the sixth reset member 105 is preferably a spring, and the sixth reset member 105 can drive the linkage block 103 to slide in the first direction by elastic force so that the linkage block 103 drives the second locking block 101 and the third locking block 102 to respectively extend from the two sides of the mounting seat 52.

[0205] Referring to Figure 27 and Figure 31 It can be understood that, in order to avoid the first sliding insertion part 522 and the second sliding insertion part 611 from being blocked when being assembled, the second locking block 101 and the third locking block 102 can be respectively provided with inclined surfaces, so that the bottom connecting plate 61 can push the second locking block 101 and the third locking block 102 to shrink into the mounting seat 52 through the inclined surfaces when being inserted, until the second locking block 101 and the third locking block 102 are respectively positioned corresponding to the second lock hole 612 and the third lock hole 613, and then the second locking block 101 is inserted into the second lock hole 612 and the third locking block 102 is inserted into the third lock hole 613 under the elastic force of the sixth reset member 105, so as to complete the locking. Of course, other ways can also be used to realize the function of shrinking the second locking block 101 and the third locking block 102 into the mounting seat 52 when being inserted, such as providing inclined surfaces on the bottom connecting plate 61, and the like, and the present embodiment does not limit the way of realizing the function of shrinking the second locking block 101 and the third locking block 102 into the mounting seat 52 when being inserted.

[0206] Based on the above-mentioned third locking and unlocking mechanism 100, when it is needed to unlock the seat frame 6 from the mounting seat 52, the bottom connecting plate 61 is pulled out from the mounting seat 52 along the second direction, the second locking block 101 and the third locking block 102 are driven by the linkage block 103 to slide in the first direction, and the second locking block 101 and the third locking block 102 are driven by the first protruding column 1011 and the second protruding column 1021 to slide out of the second lock hole 612 and the third lock hole 613, so as to realize the unlocking. Figure 27The shown direction is reference, the process is as follows: press the third switch 104, the third switch 104 will push the second lock block 101 to slide into the mounting seat 52, make the second lock block 101 disengage from the second lock hole 612, at the same time, when the second lock block 101 slides inwards, the second lock block 101 will drive the linkage block 103 to slide leftwards through the sliding cooperation of the first protruding column 1011 and the first linkage inclined slot 1031, when the linkage block 103 slides leftwards, it will drive the third lock block 102 to slide into the mounting seat 52 through the sliding cooperation of the second protruding column 1021 and the second linkage inclined slot 1032, so as to make the third lock block 102 disengage from the third lock hole 613, thus, the unlocking of the double lock blocks is realized, at this time, the bottom connecting plate 61 and the mounting seat 52 can be relatively disassembled.

[0207] In other preferable embodiments, the linkage block 103 can also adopt a rotating mode, for example, the middle part of the linkage block 103 is pivoted to the mounting seat 52, one end of the linkage block 103 is connected with the second lock block 101, and the other end of the linkage block 103 is connected with the third lock block 102, when the second lock block 101 slides, it can drive the linkage block 103 to rotate, when the linkage block 103 rotates, it can pull the third lock block 102 to slide and contract, of course, at this time, the sixth reset member 105 is preferably a torsion spring and acts on the linkage block 103, or the sixth reset member 105 is a spring and acts on the second lock block 101 or the third lock block 102.

[0208] In other preferable embodiments, the third locking and unlocking mechanism 100 can also adopt any known structure to meet the locking or unlocking function between the frame and the mounting seat 52, which will not be listed one by one here.

[0209] In the embodiment, in order to avoid accidental unlocking caused by accidental pressing of the third switch 104, as a preferred solution, the third switch 104 comprises a pushing piece 1041, a third sliding block 1042, an eighth reset piece 1043, and a connecting block 1044. The pushing piece 1041 is slidably arranged on the bottom connecting plate 61 and can abut against the second lock block 101. The third sliding block 1042 is slidably arranged on the pushing piece 1041. The eighth reset piece 1043 is arranged between the pushing piece 1041 and the third sliding block 1042. The eighth reset piece 1043 is preferably a spring. The connecting block 1044 is clamped on the pushing piece 1041 and is used to limit the third sliding block 1042 from disengaging from the pushing piece 1041. The third sliding block 1042 has an extended state and a retracted state. Specifically, the pushing piece 1041 is slidably arranged on the pushing piece 1041 in the second direction, and the third sliding block 1042 is slidably arranged on the pushing piece 1041 in the vertical direction. Under the elastic force of the eighth reset piece 1043, the third sliding block 1042 can slide downward and extend below the pushing piece 1041, so that the third sliding block 1042 is in the extended state, or when driven by an external force, the third sliding block 1042 can slide upward and retract into the pushing piece 1041, so that the third sliding block 1042 is in the retracted state. When the third sliding block 1042 is in the extended state, the third sliding block 1042 can abut against the outer side wall of the bottom connecting plate 61, thereby preventing the pushing piece 1041 from sliding, and thereby preventing the second lock block 101 and the third lock block 102 from being unlocked. When the third sliding block 1042 is in the retracted state, the third sliding block 1042 is disengaged from the outer side wall of the bottom connecting plate 61, and at this time the pushing piece 1041 can be pressed to drive the second lock block 101 and the third lock block 102 to be unlocked. In this way, the third switch 104 described above provides protection by using the third sliding block 1042, and two-step actions of pressing the third sliding block 1042 first and then pressing the pushing piece 1041 are required when unlocking, thereby avoiding accidental unlocking caused by accidental pressing.

[0210] Of course, the third sliding block 1042 can also be slidably arranged on the pushing piece 1041 in other directions, so that the third sliding block 1042 can extend upward or extend to the left or extend to the right.

[0211] Referring to Figure 34 and 35 In the embodiment, the same as in Embodiment 1, the swinging part 531 comprises a swing arm 5311, a rotating shaft 5312, a limiting piece 5313, and a limiting groove 5314. The technical features of the swing arm 5311, the rotating shaft 5312, the limiting piece 5313, and the limiting groove 5314 are described with reference to Embodiment 1. Different from Embodiment 1, the swinging part 531 further comprises a conversion device 5315. One end of the rotating shaft 5312 is fixedly arranged with one end of the conversion device 5315, and the other end of the conversion device 5315 penetrates out of the movable shell 31 and is fixedly arranged with the mounting seat 52. The connection part of the conversion device 5315 and the mounting seat 52 is close to the middle of the swing arm 5311.

[0212] In the above scheme, by setting the adapter 5315 to connect the rotating shaft 5312 and the mounting seat 52, and making the connection between the adapter 5315 and the mounting seat 52 closer to the middle of the swing arm 5311, the swing speed of the seat frame 6 is ensured to be slow and the swing range is large, and the adapter 5315 is used to make the connection of the mounting seat 52 located at the space in the middle of the swing arm 5311, so that when the seat frame 6 needs to be designed to be relatively centered with the shell 3, the volume of the shell 3 can be made smaller without affecting the connection of the mounting seat 52 to be close to the center position of the shell 3, and the center of gravity of the seat frame 6 can approximately correspond to the center position of the shell 3, so as to form a baby care device with small volume, low cost and overall symmetry and beauty.

[0213] On the other hand, since the connection between the adapter 5315 and the mounting seat 52 is closer to the middle of the swing arm 5311, the moment of force of the seat frame 6 acting on the swing arm 5311 through the mounting seat 52 will also be relatively small, which is beneficial to reduce the rotational wear between the first pivot shaft and the swing arm 5311 or the rotational wear between the first pivot shaft and the connecting part 51, and the swing arm 5311 is not easy to bend downward and deform relative to the first pivot shaft or the swing arm 5311 and the first pivot shaft are not easy to bend downward and deform relative to the connecting part 51, so as to ensure the balance of the seat frame 6 and avoid the sliding of the seat frame 6.

[0214] When designing the size of the shell 3, only the length of the swing arm 5311 and the necessary space required by other structures need to be considered, at this time the shell 3 can be made as small as possible, the overall space utilization is high, and the center of gravity of the seat frame 6, the center of the mounting seat 52 and the center of the shell 3 can approximately correspond to each other, at this time the baby care device has slow swing speed, large swing range, small shell 3 volume, and the mounting seat 52 does not need to form a protruding part to meet the stable support of the seat frame 6 when swinging, the whole is symmetrical, neat and beautiful, which meets the dual design requirements of function and appearance.

[0215] Referring to Figure 34 , the adapter 5315 includes a horizontal part 5316 and a vertical part 5317, one end of the horizontal part 5316 is connected with one end of the rotating shaft 5312, the other end of the horizontal part 5316 is closer to the middle of the swing arm 5311 and is connected with one end of the vertical part 5317, the other end of the vertical part 5317 penetrates out of the movable shell 31 and is connected with the mounting seat 52, so as to realize the connection of the adapter 5315 with the rotating shaft 5312 and the mounting seat 52, facilitate the installation of the mounting seat 52 and the vertical part 5317, and have good strength. In particular, the mounting seat 52 and the vertical part 5317 are detachably inserted.

[0216] In the embodiment, the horizontal part 5316 and the vertical part 5317 are preferably integrally bent and formed or welded and fixed or screwed and fixed. More preferably, the vertical part 5317 is in the shape of a rod, so that the movable track of the vertical part 5317 is small and the vertical part 5317 is less likely to interfere with the top wall of the movable shell 31, the avoiding groove 315 on the movable shell 31 can be relatively small, the whole is more beautiful and conducive to improving the dustproof effect.

[0217] Referring to Figure 34 In the embodiment, the driving mechanism 53 further comprises a first transmission assembly 533, the first motor 532 and the swing arm 5311 are drivingly connected through the first transmission assembly 533, and a specific structure of the first transmission assembly 533 can be selected as follows: the first transmission assembly 533 comprises a first driven wheel 5331, a first worm 5332, a first worm wheel 5333, a second rotating piece 5334, and a first swing piece 5335, the output shaft of the first motor 532 is fixedly connected with a first driving wheel 5321, the first worm 5332 is pivotally connected to the connecting part 51, the first driven wheel 5331 is fixedly connected to the first worm 5332, the first driving wheel 5321 and the first driven wheel 5331 are drivingly connected, preferably the first driving wheel 5321 and the first driven wheel 5331 are belt wheels, the diameter of the first driven wheel 5331 is greater than that of the first driving wheel 5321, a first transmission belt 5322 is wound around the first driving wheel 5321 and the first driven wheel 5331, the first worm wheel 5333 is pivotally connected to the connecting part 51 and engaged with the first worm 5332, one end of the second rotating piece 5334 is fixedly connected to the shaft of the first worm wheel 5333, the other end of the second rotating piece 5334 is pivotally connected to one end of the first swing piece 5335, the other end of the first swing piece 5335 is pivotally connected to the swing arm 5311, wherein the pivot connection point of the second rotating piece 5334 and the first swing piece 5335 is offset from the axis of the first worm wheel 5333, and the pivot connection point of the first swing piece 5335 and the swing arm 5311 is offset from the pivot connection point of the swing arm 5311 and the connecting part 51. Based on the structure of the connecting part 51 in the embodiment, the first worm 5332, the first worm wheel 5333, and the swing arm 5311 are pivotally connected to the bearing seat 54 in the connecting part 51.

[0218] The prior art is to drive the swing arm 5311 to swing by the way of the forward and reverse rotation of the motor. The length of the swing arm 5311 affects the swing speed of the seat frame 6. The longer the swing arm 5311 is, the slower the swing speed of the seat frame 6 is, and the shorter the swing arm 5311 is, the faster the swing speed of the seat frame 6 is. Because the swing speed of the seat frame 6 needs to be controlled to be slow, the swing arm 5311 is generally made to be long, which causes the overall volume to be large. Therefore, compared with the prior art, the first transmission assembly 533 of the embodiment can realize high transmission ratio and directly control the swing speed of the swing arm 5311. The swing arm 5311 can be designed to be shorter, and the child sitting on the seat frame 6 is more comfortable when swinging. In addition, self-locking can be realized by using a worm gear. When the seat frame 6 needs to be locked, an additional locking mechanism is not needed, thereby saving cost. When the first motor 532 is started, the first motor 532 drives the first driving wheel 5321 to rotate. The first driving wheel 5321 drives the first driven wheel 5331 to rotate through the first transmission belt 5322. The first driven wheel 5331 drives the first worm 5332 to rotate. The first worm 5332 drives the first worm wheel 5333 to rotate. The first worm wheel 5333 drives the second rotating part 5334 to rotate. The second rotating part 5334 drives the first swing part 5335 to swing. The first swing part 5335 drives the swing arm 5311 to swing, thereby driving the seat frame 6 to swing reciprocatingly relative to the connecting part 51. When the first motor 532 stops, the seat frame 6 can be fixed at a preset position, thereby further meeting more needs of consumers.

[0219] It should be noted that in other embodiments, the first transmission assembly 533 can also adopt any known structure as long as the function of driving the seat frame 6 to swing reciprocatingly can be realized. The specific structure of the first transmission assembly 533 is not limited herein.

[0220] Referring to Figures 32 to 35 In the embodiment, the limiting groove 5314 is movably arranged relative to the connecting part 51, and specifically, the limiting groove 5314 is hinged above the bearing seat 54. The swing mode adjusting mechanism 9 for adjusting the position of the limiting groove 5314 is further included, thereby realizing multiple swing modes of the baby care equipment when the cradle is used by using the swing mode adjusting mechanism 9.

[0221] Different from embodiment 1, the preferred scheme of the swing mode adjusting mechanism 9 adopted in the embodiment is that the swing mode adjusting mechanism 9 comprises a second motor 98, a second transmission assembly 99, the second transmission assembly 99 comprising a second driving wheel 981, a second worm 992, a second worm wheel 993, a third rotating piece 994, a second swing piece 995, the output shaft of the second motor 98 being fixedly connected with the second driving wheel 981, the second worm 992 being pivotally connected with the connecting part 51, the second driving wheel 991 being fixedly connected with the second worm 992, the second driving wheel 981 and the second driving wheel 991 being in transmission connection, the second driving wheel 981 and the second driving wheel 991 preferably being belt wheels, and the diameter of the second driving wheel 991 being greater than that of the second driving wheel 981, a second transmission belt 982 being wound around the second driving wheel 981 and the second driving wheel 991, the second worm wheel 993 being pivotally connected with the connecting part 51 and in meshing connection with the second worm 992, one end of the third rotating piece 994 being fixedly connected with the shaft of the second worm wheel 993, the other end of the third rotating piece 994 being pivotally connected with one end of the second swing piece 995, the other end of the second swing piece 995 being pivotally connected with the limiting groove 5314, the limiting groove 5314 being pivotally connected with the connecting part 51, wherein the pivot connection point of the third rotating piece 994 and the second swing piece 995 is away from the shaft center of the second worm wheel 993, and the pivot connection point of the second swing piece 995 and the limiting groove 5314 is away from the pivot connection point of the limiting groove 5314 and the connecting part 51. Based on the structure of the connecting part 51 of the embodiment, the second worm 992, the second worm wheel 993 and the limiting groove 5314 will be pivotally connected with the bearing seat 54 in the connecting part 51.

[0222] Thus, high transmission ratio is achieved, self-locking can be realized by using the worm wheel and worm, no additional locking mechanism is needed when the limiting groove 5314 needs to be locked, thereby saving cost; when the second motor 98 is started, the second motor 98 drives the second driving wheel 981 to rotate, the second driving wheel 981 drives the second driving wheel 991 to rotate through the second transmission belt 982, the second driving wheel 991 drives the second worm 992 to rotate, the second worm 992 drives the second worm wheel 993 to rotate, the second worm wheel 993 drives the third rotating piece 994 to rotate, the third rotating piece 994 drives the second swing piece 995 to swing, and the second swing piece 995 drives the limiting groove 5314 to swing, thereby changing the position of the limiting groove 5314 and the rotating amplitude of the rotating shaft 5312 relative to the swing arm 5311, and further making the rotating shaft 5312 drive the seat frame 6 to deflect, thereby increasing the swing mode of the seat frame 6; when the second motor 98 stops, the limiting groove 5314 can be fixed at a preset position.

[0223] Referring to Figure 32 and Figure 33, in order to make full use of space, preferably, the swing mode adjusting mechanism 9 is located on the first side of the swing arm 5311, and the first motor 532 and the first transmission assembly 533 are located on the second side of the swing arm 5311. In this way, the space on both sides of the swing arm 5311 is fully utilized to arrange the first motor 532, the first transmission assembly 533 and the swing mode adjusting mechanism 9, that is, it is beneficial to distribute the weight, save the height space, avoid interference, and it is beneficial to reduce the size of the shell 3, and it is more neat and beautiful.

[0224] Referring to Figure 39 and Figure 40 , based on the above scheme, the first motor 532 can drive the seat frame 6 to act alone, or the second motor 98 can drive the seat frame 6 to act alone, or the first motor 532 and the second motor 98 can drive the seat frame 6 to act simultaneously, thereby increasing the swing mode of the baby care device.

[0225] Referring to Figure 24 , Figure 25 and Figure 32 , in this embodiment, the arrangement direction of the two lifting rod assemblies 4 is the same as the length direction of the initial position of the seat frame 6. Of course, this is only preferred based on the driving mechanism 53 scheme of the embodiment.

[0226] Referring to Figure 32 and Figure 36 , unlike the travel of the reinforcing sleeve 71 being limited by the connecting device 5 in Embodiment 1, in this embodiment, the reinforcing sleeve 71 is provided with travel limitation by the movable rod 41. Among them, the movable rod 41 is sleeved on the outside of the fixed rod 42, the reinforcing sleeve 71 is slidably arranged on the movable rod 41, the movable rod 41 is provided with a limiting piece 44 for supporting the reinforcing sleeve 71, and the second reset piece 72 is arranged between the reinforcing sleeve 71 and the connecting device 5. When the reinforcing sleeve 71 and the base 2 abut when the connecting device 5 descends to the low position, the base 2 can push the reinforcing sleeve 71 upward to make the reinforcing sleeve 71 disengage from the limiting piece 44 and compress the second reset piece 72.

[0227] Specifically, the reinforcing sleeve 71 is provided with a second through hole 711 for the movable rod 41 to pass through, and the limiting piece 44 is supported at the lower end of the second through hole 711. In this way, the reinforcing sleeve 71 can use the action of the movable rod 41 to make the reinforcing sleeve 71 not easy to deform and have better support effect, and at the same time, the reinforcing sleeve 71 can also limit the torsion of the movable rod 41 in the opposite direction, so that the seat frame 6 is more stable.

[0228] For the effect of the reinforcing sleeve 71, as described in the embodiment 1, the circumferential side wall of the reinforcing sleeve 71 can be used to slide against the inner side wall of the movable shell 31 or the circumferential side wall of the reinforcing sleeve 71 can be used to slide against the inner side wall of the fixed shell 32, when installed, the reinforcing sleeve 71 can be located at the lower open end of the movable shell 31 or the reinforcing sleeve 71 can be located at the upper open end of the fixed shell 32, so as to use the reinforcing sleeve 71 to provide more comprehensive support for the outer shell 3. Similarly, the circumferential side wall of the reinforcing sleeve 71 can directly abut against the inner side wall of the movable shell 31 or the circumferential side wall of the reinforcing sleeve 71 can directly abut against the inner side wall of the fixed shell 32, thereby forming direct support; or the circumferential side wall of the reinforcing sleeve 71 can have a gap with the inner side wall of the movable shell 31 which can be eliminated or the circumferential side wall of the reinforcing sleeve 71 can have a gap with the inner side wall of the fixed shell 32 which can be eliminated, thereby forming support after a small amount of deformation of the outer shell 3.

[0229] When the reinforcing sleeve 71 abuts against the limiting piece 44, the reinforcing sleeve 71 is at the lower stroke point, and when the reinforcing sleeve 71 abuts against the connecting device 5, the reinforcing sleeve 71 is at the upper stroke point, thus, the reinforcing sleeve 71 has the upper stroke point and the lower stroke point relative to the movable rod 41, and also has the upper stroke point and the lower stroke point relative to the connecting device 5, wherein the size of the preset stroke is determined according to the needs, and the second reset piece 72 can keep the reinforcing sleeve 71 at the lower stroke point, so that when the seat frame 6 rises to the highest position, the circumferential side wall of the reinforcing sleeve 71 can also well abut against the inner side wall at the upper open end of the fixed shell 32, without the need to intentionally heighten the fixed shell 32, if the fixed shell 32 is heightened, since the movable shell 31 is sleeved outside the fixed shell 32, it will affect the seat frame 6 to be unable to descend lower; and when the seat frame 6 descends to the lowest position, the base 2 can push the reinforcing sleeve 71 to slide upward relative to the movable rod 41 and the connecting device 5 to compress the second reset piece 72, and the reinforcing sleeve 71 will not hinder the descent of the seat frame 6, thus, under the guarantee of the supporting effect of the reinforcing sleeve 71 on the outer shell 3, the seat frame 6 can descend lower to meet more use requirements of consumers.

[0230] Further preferably, the second reset piece 72 is provided with four, the second reset piece 72 is preferably a spring, the reinforcing sleeve 71 is provided with four first spring grooves 73, the connecting device 5 is provided with four second spring grooves 541, one end of the second reset piece 72 is inserted into the first spring groove 73, and the other end of the second reset piece 72 is inserted into the second spring groove 541, thus the first spring groove 73 and the second spring groove 541 can be used to position the second reset piece 72, so that the second reset piece 72 is not easy to loosen, and preferably four second reset pieces 72 are at four corners to form balanced elastic force to keep the reinforcing sleeve 71 horizontal.

[0231] Of course, the number of the second reset piece 72 can also be two, three, five, six, etc., and the specific number of the second reset piece 72 is not limited here.

[0232] Referring to Figure 32 and Figure 36 In this embodiment, the second lock-unlock mechanism 43 also comprises a second lock-unlock part 431, a second transmission part 432 and a second switch assembly 433. The second lock-unlock part 431 is arranged between the movable rod 41 and the fixed rod 42. One end of the second transmission part 432 is connected with the second lock-unlock part 431, and the other end of the second transmission part 432 is connected with the second switch assembly 433. Different from the first embodiment, the movable rod 41 is slidingly sleeved outside the fixed rod 42, and the second switch assembly 433 is arranged on the base 2 or the support leg 1 or the fixed housing 32. Preferably, the second switch assembly 433 is arranged on the base 2.

[0233] In the prior art, the second switch assembly 433 is generally arranged on the seat frame 6. Since the seat frame 6 is swingable, the second transmission part 432 needs to pass through the movable housing 31 and extend upward to the seat frame 6, so the second transmission part 432 needs to be relatively long. Moreover, since the seat frame 6 is swingable and detachable, the seat frame 6 is easy to interfere when swinging, and the second transmission part 432 also needs to be made into two detachable parts, so the structure is relatively complex, the operation is not convenient, the cost is high, and the appearance is not beautiful.

[0234] In this embodiment, the movable rod 41 is slidingly sleeved outside the fixed rod 42, and the second switch assembly 433 is arranged on the base 2, so that the second transmission part 432 does not need to move when the lifting rod assembly 4 is lifted, which is beneficial to the wiring of the second transmission part 432. That is, the problem of interference when the seat frame 6 swings is avoided, the operation is convenient, the second transmission part 432 can be made relatively short, the cost is saved, and the appearance is more beautiful.

[0235] Referring to Figures 36 to 38 , and Figure 41 and Figure 42As known, the movable rod 41 is sleeved outside the fixed rod 42 in a sliding manner, different from the embodiment 1, the plurality of first lock holes 422 arranged in the vertical direction are no longer arranged on the side wall of the fixed rod 42, but a plurality of fourth lock holes 412 arranged in the vertical direction are arranged on the side wall of the movable rod 41, in addition, in the second locking and unlocking part 431, the lifting lock block 4311 is horizontally slidably arranged on the upper block 421 in the fixed rod 42, the lifting lock block 4311 can be inserted and matched with the fourth lock hole 412, the lifting sliding block 4312 is also vertically slidably arranged on the upper block 421 in the fixed rod 42, the fourth reset member 4313 is arranged between the upper block 421 in the fixed rod 42 and the lifting sliding block 4312, or the fourth reset member 4313 is arranged between the upper block 421 in the fixed rod 42 and the lifting lock block 4311, the fourth reset member 4313 can provide elastic force to reset the lifting sliding block 4312 and the lifting lock block 4311.

[0236] When the second switch assembly 433 is operated, the second switch assembly 433 drives the lifting sliding block 4312 to slide downward through the second transmission member 432, and the lifting sliding block 4312 drives the lifting lock block 4311 to slide under the cooperation of the first protrusion 43111 and the first inclined groove 43121, so that the lifting lock block 4311 is separated from the fourth lock hole 412 to complete unlocking, at this time the movable rod 41 can be lifted relative to the fixed rod 42, when the second switch assembly 433 is released, the lifting lock block 4311 reversely slides to insert into the fourth lock hole 412 to complete locking under the elastic force of the fourth reset member 4313, and the lifting sliding block 4312 slides upward to reset.

[0237] Specifically, the second switch assembly 433 includes a switch pedal 4336, a fourth rotating member 4337, and a seventh reset member 4338, the fourth rotating member 4337 is pivoted to the base 2 in the horizontal direction, the other end of the second transmission member 432 is connected with the fourth rotating member 4337, the seventh reset member 4338 is arranged between the base 2 and the fourth rotating member 4337, the switch pedal 4336 is pivoted to the fourth rotating member 4337 in the vertical direction, and the switch pedal 4336 has an open state and a folding state. Figure 32 and Figure 41 As shown in the figures, when the switch pedal 4336 is in the open state, the switch pedal 4336 rotates outward relative to the fourth rotating member 4337 to be exposed, at this time the switch pedal 4336 can be stepped on to drive the fourth rotating member 4337 to rotate relative to the base 2, the fourth rotating member 4337 drives the second locking and unlocking part 431 through the second transmission member 432, so that the second locking and unlocking part 431 releases the locking of the movable rod 41 and the fixed rod 42. Figure 42As shown, when the switch pedal 4336 is in the collapsed state, the switch pedal 4336 is rotated inward relative to the fourth rotating member 4337 and hidden below the base 2, thereby preventing the switch pedal 4336 from being stepped on, so that the second lock unlocking portion 431 keeps the movable rod 41 and the fixed rod 42 locked and unable to lift. In addition, when transporting, the switch pedal 4336 can be in the collapsed state, thereby hiding the switch pedal 4336 below the base 2, reducing the occupied packaging space, making the packaging volume smaller, and the appearance more beautiful.

[0238] Further preferably, the fourth rotating member 4337 is provided with a spring positioning pin 4339, and the switch pedal 4336 is provided with at least one pin hole 43361 matched with the spring positioning pin 4339. When the switch pedal 4336 is in the open state, the spring positioning pin 4339 can be embedded in the pin hole 43361 to position the switch pedal 4336, so that the switch pedal 4336 can be prevented from loosening during normal use.

[0239] On the other hand, when the second switch assembly 433 is installed on the base 2, the switch pedal 4336 can be controlled by the foot without the need to use the hand, so that the two hands can be left free to adjust the height of the seat frame 6, thereby facilitating the operation when adjusting the height of the seat frame 6.

[0240] Referring to Figure 32 and Figure 33 The same as in Embodiment 1, in this embodiment, the connecting portion 51 also includes a first connecting member 511, a second connecting member 512, and a U-shaped tube 513. The first connecting member 511 is connected to the upper end of one movable rod 41, the second connecting member 512 is connected to the upper end of the other movable rod 41, and the two ends of the U-shaped tube 513 are upwardly directed and connected to the first connecting member 511 and the second connecting member 512, respectively. The difference is that two U-shaped tubes 513 are provided in this embodiment, and the two U-shaped tubes 513 are arranged oppositely. The connecting portion 51 further includes a bearing seat 54 connected to the two U-shaped tubes 513, and the driving mechanism 53 is arranged on the bearing seat 54.

[0241] Specifically, the two U-shaped tubes 513 are arranged on opposite sides of the movable rod 41 along the second direction, thereby forming a symmetrical support for the bearing seat 54, thereby better supporting the driving mechanism 53, and further better supporting the mounting seat 52 and the seat frame 6.

[0242] Preferably, the U-shaped tube 513 comprises two vertical tubes 5132 and a horizontal tube 5131, two ends of the horizontal tube 5131 are connected to one end of the different vertical tubes 5132 respectively, the other end of the two vertical tubes 5132 extends upward and is connected to the first connecting member 511 and the second connecting member 512 respectively, the bearing seat 54 is connected to the two horizontal tubes 5131, and specifically, the two fixing blocks 55 are installed on the horizontal tube 5131 respectively, and when installed, the bolt is sequentially passed through the fixing block 55, the horizontal tube 5131 and is screwed to the bearing seat 54 from bottom to top, so that the bearing seat 54 is more stably installed on the two U-shaped tubes 513.

[0243] Referring to Figure 32 In the embodiment, preferably, the buffering mechanism 200 is connected between the base 2 and the connecting device 5, and when the height of the seat frame 6 is adjusted, the buffering mechanism 200 can provide a buffering effect, absorb the impact force when falling, avoid falling too fast, and avoid a large impact when reaching the low position. In addition, when the seat frame 6 is accidentally loosened during adjustment, or when the second locking and unlocking mechanism 43 is unlocked without following the instructions or misoperation, the seat frame 6 is not held, and the buffering mechanism 200 can prevent the rapid descent of the seat frame 6, avoiding shocking and injuring children.

[0244] Preferably, the buffering mechanism 200 comprises two buffering springs 201, one end of the buffering spring 201 is connected to the connecting device 5, and the other end of the buffering spring 201 is connected to the base 2. Of course, the number of buffering springs 201 can also be one, three, four, etc., and the number of buffering springs 201 is not limited in the embodiment. In this way, the buffering spring 201 can absorb the impact force when the height of the seat frame 6 is adjusted, and can also provide an upward auxiliary force when the height of the seat frame 6 is adjusted, thereby saving effort, making the adjustment of the seat frame 6 more secure and more relaxed. In addition, because of the upward auxiliary force of the buffering spring 201, the cooperation gap between the movable rod 41 and the fixed rod 42 can be smaller, the upward auxiliary force of the buffering spring 201 can offset or at least partially offset the friction when the movable rod 41 rises relative to the fixed rod 42 (the friction when the movable rod 41 falls relative to the fixed rod 42 can be offset by gravity), so that the swinging drive of the driving mechanism 53 is more smooth, more stable, the energy loss is smaller, and the seat frame 6 is more stable.

[0245] It should be noted that the buffering mechanism 200 can also be realized by other means to provide a buffering effect when the height of the seat frame 6 is adjusted, such as a damper or other structures, and the specific structure of the buffering mechanism 200 is not limited herein.

[0246] Embodiment 3

[0247] Referring to Figures 43 to 58The embodiment also discloses an infant care device. The infant care device of the embodiment is different from the infant care device of the embodiment 1 or 2 in that a new mounting structure of the switch pedal 4336 is adopted, the mounting structure of the buffer spring 201 is optimized, the mounting structure of the support leg 1 is optimized, the mounting structure of the control panel 300 is added, the connection device 5 is different, and a new seat frame 6 is adopted.

[0248] The infant care device of the embodiment can also realize the relative fixed connection of the fixed rod 42 in the plurality of lifting rod assemblies 4 through the base 2, realize the relative fixed connection of the movable rod 41 in the plurality of lifting rod assemblies 4 through the connection device 5, and cover the lifting rod assemblies 4 and at least part of the connection device 5 in the accommodation cavity by using the sleevable movable shell 31 and the fixed shell 32, so as to form a modular unit which is not exposed when the lifting rod assemblies 4 are lifted. The modular unit can be arranged to be small in size, beautiful in appearance and low in cost. The support leg 1 is connected with the base 2, and the seat frame 6 is connected with the connection device 5. The support leg 1 can be folded, contracted or detached from the base 2, and the seat frame 6 can be folded, contracted or detached from the connection device 5. When transported, the lifting rod assemblies 4 do not need to be detached, and only the support leg 1 needs to be detached from the base 2 and the seat frame 6 needs to be detached from the connection device 5. The support stability provided by the lifting rod assemblies 4 is high and the infant care device is not easy to shake when the infant care device is normally used. The overall size of the infant care device can be greatly reduced when transported, and the overall comprehensive performance of the infant care device is greatly improved.

[0249] Thus, the embodiment can also solve the same technical problems as shown in the embodiment 1 and achieve the same technical effects as shown in the embodiment 1.

[0250] In order to reduce the length, the same technical features of the embodiment and the embodiment 1 or 2 will not be repeated in the following description, and only the different parts will be described.

[0251] Referring to Figure 51 , Figure 52 , Figure 57 and Figure 58 , compared with the lifting rod assembly 4 of the embodiment 2, the difference in the embodiment is only that the connection mode of the switch pedal 4336 on the fourth rotating piece 4337 is changed. The switch pedal 4336 is detachably inserted on the fourth rotating piece 4337. As for other structures of the lifting rod assembly 4, such as that the movable rod 41 is slidingly sleeved on the outside of the fixed rod 42, the structure of the second locking and unlocking part 431, the structure of the second transmission part 432, the fourth rotating piece 4337, and the seventh reset part 4338, reference can be made to the related description in the embodiment 2, which will not be repeated here.

[0252] In order to realize the plug-in and locking of the switch pedal 4336 on the fourth rotating piece 4337, refer to Figure 57 and Figure 58 In the embodiment, specifically, the fourth rotating piece 4337 is pivoted with the base 2 through the second pivoting shaft 43371, and the pedal locking piece 43372 is further arranged on the fourth rotating piece 4337 and is rotatably arranged around the second pivoting shaft 43371, the pedal slot 43362 is arranged on the switch pedal 4336, the pedal plug 43373 is arranged on the pedal locking piece 43372, and the pedal plug 43373 and the pedal slot 43362 are matched and locked, of course, the arrangement objects of the pedal slot 43362 and the pedal plug 43373 can also be interchanged, for example, the pedal slot 43362 is arranged on the pedal locking piece 43372, and the pedal plug 43373 is arranged on the switch pedal 4336; the tenth reset piece 43374 is further arranged between the pedal locking piece 43372 and the fourth rotating piece 4337, the tenth reset piece 43374 provides a reset force to make the pedal plug 43373 inserted into the pedal slot 43362 to form the locking, and the tenth reset piece 43374 can be specifically a spring, a spring piece or other structure providing a reset force.

[0253] In this way, during the transportation, the pedal locking piece 43372 can be pressed to make the pedal plug 43373 and the pedal slot 43362 disengaged, so that the switch pedal 4336 can be detached from the fourth rotating piece 4337, thereby reducing the occupied packaging space, making the packaging volume smaller and the appearance more beautiful; and in the above scheme, the pedal locking piece 43372 and the fourth rotating piece 4337 share the second pivoting shaft 43371 as the rotation shaft, so that the structure is simplified and the cost is saved.

[0254] Refer to Figure 58 Since the fourth rotating piece 4337 is rotated relative to the base 2 to pull the second transmission piece 432 when the switch pedal 4336 is stepped, that is, the second transmission piece 432 is easy to rub against the base 2, in order to solve the friction problem, the anti-wear piece 26 for abutting against the second transmission piece 432 is arranged on the base 2, the anti-wear piece 26 is close to the connection position of the second transmission piece 432 and the second switch assembly 433, so as to protect the base 2 from being worn by the second transmission piece 432 when the fourth rotating piece 4337 pulls the second transmission piece 432.

[0255] Of course, the anti-wear piece 26 can also be arranged at other positions where the second transmission piece 432 is easy to rub, and the anti-wear piece 26 is preferably made of plastic material, and can be specifically a gasket shape or a strip shape with a wiring groove or a ring shape for the second transmission piece 432 to pass through.

[0256] It should be noted that the detachable plug-in scheme between the switch pedal 4336 and the fourth rotating piece 4337 in the embodiment can also be applied to the baby care equipment in Embodiment 2; the protection scheme of the wear-resistant piece 26 on the second transmission piece 432 can also be applied to the baby care equipment in Embodiment 2, or the installation position of the wear-resistant piece 26 can be adaptively changed to be applied to the baby care equipment in Embodiment 1.

[0257] Referring to Figure 51 and Figure 52 , the reinforcing sleeve 71 and the buffer spring 201 are also provided in the embodiment, the reinforcing sleeve 71 is also connected with the connecting device 5, and the functions of the reinforcing sleeve 71 and the buffer spring 201 can be referred to the related description in Embodiments 1 or 2. The specific connection scheme of the reinforcing sleeve 71 and the connecting device 5 is not limited, and as a specific example, the reinforcing sleeve 71 in the embodiment is fixedly connected with the connecting part 51 through a screw.

[0258] In the embodiment, in order to improve the protection of the buffer spring 201, preferably, the reinforcing sleeve 71 is provided with a downwardly open first installation slot 74, the base 2 is provided with an upwardly open second installation slot 27, and a guide column 271 is further arranged in the second installation slot 27. One end of the buffer spring 201 is inserted into the first installation slot 74, and the other end of the buffer spring 201 is inserted into the second installation slot 27 and is sleeved outside the guide column 271, and the guide column 271 is used for guiding the compression of the buffer spring 201. In this way, the installation of the buffer spring 201 is realized by using the two installation slots and the guide column 271, which can prevent the buffer spring 201 from being bent in the radial direction when being compressed, ensure the effect of absorbing impact force and providing upward auxiliary force of the buffer spring 201, and increase the service life of the buffer spring 201.

[0259] More preferably, the guide column 271 extends and protrudes towards the opening end of the second installation slot 27, and when the reinforcing sleeve 71 descends to the low position with the connecting device 5, the guide column 271 is inserted into the first installation slot 74 and forms abutment. When further improving the protection of the buffer spring 201, the insertion of the guide column 271 into the first installation slot 74 can also form the function of defining the downward stroke.

[0260] As a specific example, two buffer springs 201 are arranged, the arrangement directions of the two buffer springs 201 are arranged at an angle with the length direction of the seat frame 6, and the arrangement directions of the two buffer springs 201 are also arranged at an angle with the width direction of the seat frame 6; correspondingly, the first installation slot 74 and the second installation slot 27 are also provided with two, and one guide column 271 is arranged on each second installation slot 27. By using the diagonal arrangement mode, the internal space of the shell can be more fully utilized, which is conducive to the miniaturization of the modular unit, and the force of the buffer spring 201 acting on the connecting device 5 is more uniform and stable.

[0261] Of course, according to other design needs, the number of the buffer springs 201 can also be one, three, four, etc., and the first mounting slot 74 and the second mounting slot 27 will also have corresponding changes.

[0262] In another preferred example, the first mounting slot 74 can also be arranged on the connecting device 5, and can be specifically arranged below the connecting part 51 or below the driving box 56.

[0263] In another preferred example, the guide column 271 can also be arranged in the first mounting slot 74, and in a corresponding further optimization scheme, the guide column 271 extends and protrudes towards the opening end of the first mounting slot 74, and when the reinforcing sleeve 71 is lowered to the low position with the connecting device 5, the guide column 271 is inserted into the first mounting slot 74 and forms an abutment; or, a guide column 271 can also be arranged on both the first mounting slot 74 and the second mounting slot 27, and when the reinforcing sleeve 71 is lowered to the low position with the connecting device 5, the two guide columns 271 abut.

When the control panel 300 is embedded in the third installation slot 322, the panel locking piece 28 is rotated forward under the action of the ninth reset piece 29 to make the panel insertion buckle 281 locked into the panel insertion slot 301, so as to fix the control panel 300. When dismounting is needed, since the avoiding hole 243 penetrates to the first insertion slot 24 and the avoiding hole 243 corresponds to the position of the other end of the panel locking piece 28, the panel locking piece 28 can be pushed from the avoiding hole 243 of the first insertion slot 24 by using a tool to rotate forward, so that the panel insertion buckle 281 is separated from the panel insertion slot 301 to form unlocking.

[0270] Further preferably, the panel insertion buckle 281 is further provided with a pressing guide surface, when the control panel 300 is embedded into the third installation slot 322, the control panel 300 drives the panel locking member 28 to rotate and compress the ninth reset member 29 through the pressing guide surface, so as to form an avoidance until the panel insertion buckle 281 is in position correspondence with the panel insertion slot 301, and then the locking member is reset under the reset force of the ninth reset member 29, so that the panel insertion buckle 281 is locked into the panel insertion slot 301 to form a lock.

[0271] As a specific example, the panel locking member 28 is provided with two, and the two panel locking members 28 are symmetrically arranged for locking or unlocking the two sides of the bottom surface of the control panel 300.

In the above scheme, the driving box 56 is arranged below the connecting part 51, and the driving mechanism 53 is arranged in the driving box 56, forming a hoisting mode, improving the rational use of the height space due to the lifting required, and reducing the horizontal size of the shell, so that the volume of the formed modular unit can be smaller.

[0275] Preferably, in order to realize the installation of the connecting part 51 on the movable rod 41, the two ends of the connecting part 51 are respectively provided with a third connecting slot 5101, and the upper end of the movable rod 41 is fixedly connected in the third connecting slot 5101. A specific example can be that the upper end of the movable rod 41 is inserted into the third connecting slot 5101 and fixed by screwing.

[0276] In order to realize the installation of the driving box 56, the connecting part 51 is further provided with a fourth connecting groove 5102 which is downwardly open, and the upper part of the driving box 56 is inserted into the fourth connecting groove 5102 from bottom to top. As to the further fastening scheme, there can be: (1) further comprising a connecting pin 561 which transversely passes through the side wall of the fourth connecting groove 5102 and the upper part of the driving box 56; (2) further comprising a fastening screw which passes through the top wall of the fourth connecting groove 5102 from top to bottom and is screwed with the upper part of the driving box 56. The above-mentioned fixing scheme one and fixing scheme two can be independently used or can be used in combination.

[0277] In the embodiment, the combination of the above-mentioned fixing scheme one and fixing scheme two is adopted. Among them, the fourth connecting groove 5102 mainly plays the role of installation and positioning, the connecting pin 561 plays the role of pre-assembly and provides a certain supporting force, and the fastening screw plays the role of final fixation.

[0278] In the embodiment, the driving mechanism 53 drives the seat frame 6 to move in a circular motion, that is, the movement of the seat frame 6 includes simultaneous lifting movement and transverse movement. Specifically, the connecting device 5 further comprises a swing piece 57, a first connecting rod 58 and a second connecting rod 59, the first connecting rod 58 and the second connecting rod 59 are respectively pivotally connected between the swing piece 57 and the connecting part 51 or respectively pivotally connected between the swing piece 57 and the driving box 56, and the first connecting rod 58 and the second connecting rod 59 are used to limit the movement track of the swing piece 57; the seat frame 6 is detachably fixed with the swing piece 57, the swing piece 57 supports the seat frame 6, the driving mechanism 53 is connected with the swing piece 57, and the driving mechanism 53 drives the swing piece 57 to move in a circular motion in the vertical plane together with the seat frame 6.

[0279] In the above-mentioned scheme, the first connecting rod 58, the second connecting rod 59 and the swing piece 57 constitute a four-bar linkage mechanism, the movement track of the swing piece 57 is limited by the first connecting rod 58 and the second connecting rod 59, and under the driving action of the driving mechanism 53, the swing piece 57 moves in a circular motion in the vertical plane relative to the base 2. Since the swing piece 57 supports the seat frame 6, the seat frame 6 moves in a circular motion together with the swing piece 57. Compared with the existing repeated swing structure, the lifting height of the seat frame 6 is larger, and the entertainment is better. Compared with the existing multi-drive structure, the structure is relatively simple, the materials consumed are less, and the production cost and maintenance cost are lower. On the other hand, by utilizing the characteristic of synchronous circular motion, the speed of the transverse movement and the lifting movement of the seat frame 6 is alternately fast and slow, and the whole movement is smooth without jerk, so that the riding experience which cannot be achieved in the prior art is obtained. In this way, a baby care equipment with large movement track, simple structure, low cost, and better entertainment and experience is obtained.

[0280] As a preferred example, one end of the first connecting rod 58 is pivoted to the swing piece 57, the second end of the first connecting rod 58 is pivoted to the side of the connecting part 51, one end of the second connecting rod 59 is pivoted to the swing piece 57, and the second end of the second connecting rod 59 is pivoted to the side of the connecting part 51, so that the height space of the connecting part 51 can be utilized, the position of the swing piece 57 can be made higher, the radius of the circumferential track can be made larger, and the movement range of the seat frame 6 can be increased.

[0281] Specifically, the first connecting rod 58 and the second connecting rod 59 are arranged in parallel, the distance between the two pivot axes of the first connecting rod 58 is equal to the distance between the two pivot axes of the second connecting rod 59, and the distance between the pivot axes between the first connecting rod 58 and the swing piece 57 and between the second connecting rod 59 and the swing piece 57 is equal to the distance between the pivot axes between the first connecting rod 58 and the connecting part 51 and between the second connecting rod 59 and the connecting part 51.

[0282] Referring to Figure 54 , for the convenience of understanding, the pivot axis between the first connecting rod 58 and the connecting part 51 is defined as the first pivot axis S1, the pivot axis between the first connecting rod 58 and the swing piece 57 is defined as the second pivot axis S2, the pivot axis between the second connecting rod 59 and the connecting part 51 is defined as the third pivot axis S3, and the pivot axis between the second connecting rod 59 and the swing piece 57 is defined as the fourth pivot axis S4, at this time, the distance between the first pivot axis S1 and the second pivot axis S2 is equal to the distance between the third pivot axis S3 and the fourth pivot axis S4, and the distance between the first pivot axis S1 and the third pivot axis S3 is equal to the distance between the second pivot axis S2 and the fourth pivot axis S4. It can also be understood that, on the plane where the moving track of the swing piece 57 is located, the connecting line of the first pivot axis S1 and the second pivot axis S2, the first pivot axis S1 and the third pivot axis S3, the third pivot axis S3 and the fourth pivot axis S4, and the second pivot axis S2 and the fourth pivot axis S4 form a parallelogram. Thus, under the driving action of the driving mechanism 53, the second pivot axis S2 rotates around the first pivot axis S1, and the fourth pivot axis S4 rotates around the third pivot axis S3, so that the swing piece 57 moves in a circular motion, and the seat frame 6 is prevented from tilting.

[0283] Referring to Figure 54 and 55In the embodiment, the driving mechanism 53 comprises a third worm wheel 534, a third worm 535, a third motor 536 and a rotating rod 537. The third worm wheel 534 and the third worm 535 are arranged in the mounting cavity of the driving box 56, the third worm wheel 534 is matched with the third worm 535, the third motor 536 is arranged below the driving box 56, the third motor 536 is in transmission connection with the third worm 535, the rotating rod 537 is located at the side of the driving box 56, the first end of the rotating rod 537 is fixedly connected to the rotating shaft of the third worm wheel 534, that is, the rotating rod 537 rotates relative to the driving box 56 around the rotating shaft of the third worm wheel 534, and the second end of the rotating rod 537 is pivotally connected to the swing piece 57. It can be understood that the transmission connection between the third motor 536 and the third worm 535 can be realized by a transmission structure of a belt wheel transmission belt, and the description of the belt wheel transmission belt in Embodiment 2 can be referred to, which will not be described here.

[0284] In the above scheme, compared with the mode that three rods are stacked and respectively pivotally connected with the first connecting rod 58, the second connecting rod 59 and the rotating rod 537 (six pivotally connected points are shared, and the overall thickness is at least the thickness of two rods stacked), the utility model utilizes the swing piece 57 to pivotally connect the first connecting rod 58, the second connecting rod 59 and the rotating rod 537, and only three pivotally connected points are needed to realize the pivotally connection with the first connecting rod 58, the second connecting rod 59 and the rotating rod 537, three pivotally connected points and the thickness of at least one rod are saved, when two swing pieces 57 are adopted, six pivotally connected points and the thickness of at least two rods are saved, in this way, the overall thickness can be made thinner, and the cost is lower.

[0285] In the above scheme, compared with the mode that three rods are stacked and respectively pivotally connected with the first connecting rod 58, the second connecting rod 59 and the rotating rod 537 (six pivotally connected points are shared, and the overall thickness is at least the thickness of two rods stacked), the utility model utilizes the swing piece 57 to pivotally connect the first connecting rod 58, the second connecting rod 59 and the rotating rod 537, and only three pivotally connected points are needed to realize the pivotally connection with the first connecting rod 58, the second connecting rod 59 and the rotating rod 537, three pivotally connected points and the thickness of at least one rod are saved, when two swing pieces 57 are adopted, six pivotally connected points and the thickness of at least two rods are saved, in this way, the overall thickness can be made thinner, and the cost is lower.

[0286] In the embodiment, in order to improve the support strength and the stability of the movement, one third worm wheel 534, two rotating rods 537, two swing pieces 57, two first connecting rods 58, two second connecting rods 59 are arranged, one rotating rod 537, one swing piece 57, one first connecting rod 58 and one second connecting rod 59 correspond to form a swing unit, two swing units are arranged on two opposite sides of the driving box 56 and / or the connecting part 51, two rotating rods 537 are respectively fixedly connected to two ends of the rotating shaft of the third worm wheel 534, the seat frame 6 is detachably connected to upper ends of the two swing pieces 57, the third worm wheel 534 drives the two rotating rods 537 to rotate synchronously when rotating, thereby driving the two swing pieces 57 to do the circular movement synchronously.

[0287] Specifically, in combination with Figure 54 and Figure 56 , and taking the direction shown in Figure 56 as the reference, one rotating rod 537, one swing piece 57, one first connecting rod 58 and one second connecting rod 59 are located on the rear side of the driving box 56, and in the structure, the first end of the rear side rotating rod 537 is fixedly connected to the rear end of the rotating shaft of the third worm wheel 534, the second end of the rear side rotating rod 537 is pivotally connected to the rear side swing piece 57, the first end of the rear side first connecting rod 58 and the first end of the rear side second connecting rod 59 are respectively pivotally connected to the rear side swing piece 57, the second end of the rear side first connecting rod 58 and the second end of the rear side second connecting rod 59 are respectively pivotally connected to the rear side of the connecting part 51; the other rotating rod 537, the other swing piece 57, the other first connecting rod 58 and the other second connecting rod 59 are located on the front side of the driving box 56, and in the structure, the first end of the front side rotating rod 537 is fixedly connected to the front end of the rotating shaft of the third worm wheel 534, the second end of the front side rotating rod 537 is pivotally connected to the front side swing piece 57, the first end of the front side first connecting rod 58 and the first end of the front side second connecting rod 59 are respectively pivotally connected to the front side swing piece 57, the second end of the front side first connecting rod 58 and the second end of the front side second connecting rod 59 are respectively pivotally connected to the front side of the connecting part 51.

[0288] In the embodiment, the baby care equipment further comprises an auxiliary tension spring 400 for providing an upward auxiliary force, one end of the auxiliary tension spring 400 is connected to the swing piece 57, and the other end of the auxiliary tension spring 400 is connected to the connecting part 51. In this way, the auxiliary tension spring 400 can provide the upward auxiliary force when driving the swing piece 57 to rise, thereby saving the labor, and making the driving mechanism 53 more relaxed when driving the swing piece 57 to do the circular upward swing together with the seat frame 6.

[0289] Specifically, in order to provide a more stable upward assist force, the pendulum 57 is provided with two extension arms 571. The two extension arms 571 are arranged opposite each other on the two opposite sides of the connection between the drive mechanism 53 and the pendulum 57, and each extension arm 571 extends away from the connection between the drive mechanism 53 and the pendulum 57. The extension end of each extension arm 571 is respectively connected to one end of an auxiliary tension spring 400. At any position where the pendulum 57 is in circular motion, the angle between the length direction of any auxiliary tension spring 400 and the vertical direction is less than 35 degrees. Thus, since the connection between the auxiliary tension spring 400 and the connecting part 51 is generally on the outside, the auxiliary tension spring 400 is connected by the extension arm 571 on the pendulum 57. This allows the angle between the length direction of the auxiliary tension spring 400 and the vertical direction to be small or basically parallel when the pendulum 57 is at the lowest position of the circular motion. As a result, even if the length direction of the auxiliary tension spring 400 changes during the circular motion of the pendulum 57, the angle between it and the vertical direction can be easily controlled to be less than 35 degrees without reducing the radius of the circular motion of the pendulum 57. This is beneficial for the auxiliary tension spring 400 to generate better upward tension (i.e., upward auxiliary force).

[0290] Regarding the specific connection scheme between the auxiliary tension spring 400 and the extension arm 571, and between the auxiliary tension spring 400 and the connecting part 51, optionally, a first hook post can be provided on the outer side of the extension arm 571 of the ornament 57, and a second hook post can be provided on the outer side of the connecting part 51. One end of the auxiliary tension spring 400 is connected to the first hook post, and the other end of the auxiliary tension spring 400 is connected to the second hook post. Of course, other methods can also be used to achieve the connection between the auxiliary tension spring 400 and the extension arm 571, and between the auxiliary tension spring 400 and the connecting part 51, which are not limited here.

[0291] See Figure 43 , Figures 51 to 56 In this embodiment, since the seat 6 is installed outside the housing, the top surface of the movable housing 31 is provided with a second through groove 316. The second through groove 316 provides lateral movement space for the circular movement of the ornament 57 and / or the seat 6. Since the second through groove 316 is large and may cause dust to enter the housing, a dustproof sliding plate 500 is also provided. The dustproof sliding plate 500 is laterally slidably disposed on the connecting part 51. The dustproof sliding plate 500 covers the second through groove 316. A third through groove 501 is provided on the dustproof sliding plate 500. The connection between the seat 6 and the ornament 57 is adapted to the third through groove 501. When the ornament 57 moves in a circular motion on the vertical plane together with the seat 6, the connection between the seat 6 and the ornament 57 moves up and down relative to the dustproof sliding plate 500 at the third through groove 501, and drives the dustproof sliding plate 500 to move laterally.

[0292] The main part of the dustproof slide plate 500 is located in the movable shell 31, the middle of the dustproof slide plate 500 protrudes upward and is provided as a third through groove 501, the size of the third through groove 501 is matched with the size of the connecting part of the seat frame 6 and the swing piece 57, along the sliding direction of the dustproof slide plate 500, the third through groove 501 is smaller than the second through groove 316, and the difference is associated with the circumferential movement radius of the swing piece 57.

[0293] As a specific example, in order to realize the sliding setting of the dustproof slide plate 500 on the connecting part 51, a sliding groove is arranged on the dustproof slide plate 500, a plurality of rollers are arranged on the connecting part 51, and the rollers are matched and installed in the sliding groove, so as to reduce the friction when the dustproof slide plate 500 slides and reduce the noise when sliding.

[0295] In the embodiment, the seat frame 6 includes a bottom connecting plate 61, four bottom rods 62, an upper surrounding frame 63, two vertical rods 64 and two bottom corner connecting pieces 65, the two bottom rods 62 in each group are detachably connected to the two opposite sides of the bottom connecting plate 61, the two bottom rods 62 in each group are connected to the vertical rod 64 through the bottom corner connecting piece 65, and each vertical rod 64 is connected to the upper surrounding frame 63.

[0296] The upper surrounding frame 63 includes two upper connecting pieces 631 and a plurality of upper surrounding rods 632, the upper connecting piece 631, part of the upper surrounding rods 632, the other upper connecting piece 631 and the remaining part of the upper surrounding rods 632 are sequentially and detachably connected in series, so as to form the upper surrounding frame 63 with a required shape. It can be understood that the shapes of the upper surrounding rods 632 can be the same or different, and only for the purpose of explaining that the upper surrounding frame 63 can also be disassembled into a plurality of parts for packaging and transportation. One end of each vertical rod 64 is connected to the bottom corner connecting piece 65, and the other end of each vertical rod 64 is connected to the upper connecting piece 631.

[0297] Referring to Figure 49 And with Figure 49As a specific example, with reference to the directions shown, the several upper surrounding rods 632 can specifically include a first upper surrounding rod 6321, a second upper surrounding rod 6322, a third upper surrounding rod 6323, a fourth upper surrounding rod 6324, a fifth upper surrounding rod 6325, and a sixth upper surrounding rod 6326. The connecting pieces are T-shaped. One end of the first upper surrounding rod 6321 is detachably connected to the rear end of the connecting piece on the left side. The other end of the first upper surrounding rod 6321 is detachably connected to one end of the second upper surrounding rod 6322. The other end of the second upper surrounding rod 6322 is detachably connected to the rear end of the connecting piece on the right side. One end of the third upper surrounding rod 6323 is detachably connected to the front end of the connecting piece on the right side. The other end of the third upper surrounding rod 6323 is detachably connected to one end of the fourth upper surrounding rod 6324. The other end of the fourth upper surrounding rod 6324 is detachably connected to one end of the fifth upper surrounding rod 6325.

The other end of the sixth upper surrounding rod 6326 is detachably connected to the front end of the connecting piece on the left side. Of course, the number of upper surrounding rods 632 can be changed as needed, and the number of upper surrounding rods 632 is not specifically limited in this embodiment.

[0298] Preferably, the bottom corner connecting piece 65 is provided with a first insertion hole 651 and a second insertion hole 652. One end of one bottom rod 62 is detachably inserted into the first insertion hole 651, and the other end of the other bottom rod 62 is detachably inserted into the second insertion hole 652. The axis of the first insertion hole 651 and the axis of the second insertion hole 652 are arranged at an angle.

[0299] In the prior art, in order to facilitate packaging and transportation and for users to assemble themselves, the seat frame 6 structure as shown in Embodiments 1 or 2, the two bottom rods 62 are generally inserted into the bottom corner connecting piece 65 along the same axis, and then tightened with screws. This can cause the bottom corner connecting piece 65 to slip relative to the bottom rods 62 to produce torsion (when using screws to press against) or wobble (when using screws to penetrate the bottom rods 62, and long-term use can cause gaps to appear) when a load is applied to the seat frame 6 during use due to unbalanced load forces (single-sided weight or horizontal thrust), thereby causing the vertical rods 64 to tip over or wobble with the upper surrounding frame 63, posing a safety risk.

[0300] The detachable seat frame 6 of the present embodiment has the axis of the first insertion hole 651 and the axis of the second insertion hole 652 arranged at an angle, so that the bottom corner connecting piece 654 cannot rotate relative to the two bottom rods 62 connected thereto, so that the seat frame 6 is relatively stable when a load is applied, and does not tilt or wobble, has high stability, is safe, and the overall structure can also be extremely simple, with low production costs.

[0301] Preferably, the angle between the axis of the first insertion hole 651 and the axis of the second insertion hole 652 ranges from 70 degrees to 120 degrees, and more preferably, the angle between the axis of the first insertion hole 651 and the axis of the second insertion hole 652 is 90 degrees as an example.
