Description

Technical Field

[0001] The present invention relates to the technical field of infant and child products, and in particular to an infant and child care device. Background Art

[0002] Infant care equipment is used to care for infants and young children, alleviating the stress of caregivers. Common infant care equipment includes high chairs, rocking chairs, and cribs. These are increasingly popular with consumers, who are also placing higher demands on them. Infant care equipment is relatively large. To facilitate transportation, it needs to be disassembled or folded to reduce its size. Furthermore, a lifting mechanism is required to support the lifting of infant care equipment.

[0003] Among the existing liftable baby care equipment, some use a single lifting mechanism to support the seat frame (such as Chinese Patent 202210629642.2). However, when using a single lifting mechanism for support, the lifting mechanism has relatively high requirements for its own strength, connection strength, torsional strength and other performance. For example, high-performance pneumatic rods and other components are generally used, which will result in a higher overall cost. There are also some that use multiple lifting mechanisms to support the seat frame, such as using four lifting rod assemblies to support the four corners around the seat frame (such as Chinese Patent CN201610718331.8), or using two lifting rod assemblies arranged at large intervals along the length direction of the seat frame to support the bottom of the seat frame (such as Chinese Patent CN202020532632.3, the two lifting rod assemblies have good stability). However, since the distance between the lifting rod assemblies is relatively far, if each lifting rod assembly is individually detachable from the seat frame and the support legs, it will make it difficult to reassemble after disassembly and transportation due to The existence of multiple disassembly and assembly points in the lifting rod assembly can easily reduce the supporting stability of the lifting rod assembly and make it easy to shake. If the stability after assembly is to be ensured, the structure of the lifting rod assembly itself and the structure of the disassembly and assembly points need to be strengthened, which in turn will increase its cost; if the lifting rod assembly is set in a non-detachable manner, the overall packaging of the infant care equipment will be larger due to the long distance between the lifting rod assemblies. Even if the seat frame and support legs are folded or retracted, the overall volume reduction is extremely limited, which is not convenient for transportation; moreover, the lifting rod assemblies are all exposed, which is not beautiful.

[0004] Therefore, it is necessary to propose a new infant care device to solve the above technical problems. Summary of the Invention

DETAILED DESCRIPTION

[0036] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] See Figures 1 to 5 The present invention discloses an infant care device comprising: four supporting legs 1, a base 2, a housing 3, two lifting rod assemblies 4, a connecting device 5, and a seat frame 6. The infant care device can be specifically designed as an infant dining chair, an infant rocking chair, or an infant bed, and the seat frame 6 can be designed as a seat or bed frame for receiving an infant. In this embodiment, the infant care device is described as an infant bed, and the seat frame 6 is correspondingly a bed frame.

[0040] In this embodiment, the support leg 1 is used to support the support surface. The support leg 1 is connected to the base 2 to provide support for the base 2. The support leg 1 is foldable, retractable, or detachable from the base 2. In this embodiment, the support leg 1 is preferably detachably connected to the base 2 so that the support leg 1 can be removed from the base 2 during transportation, thereby reducing the volume during transportation. Two lifting rod assemblies 4 support the seat frame 6 through a connecting device 5. The lifting rod assembly 4 includes 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 arranged to slide relative to each other and can be locked or unlocked relative to each other. The fixed rods 42 of the two lifting rod assemblies 4 are both fixedly connected to the base 2, and the movable rods 41 of the two lifting rod assemblies 4 are both fixedly connected to the connecting device 5. The connecting device 5 is connected to the seat frame 6. The seat frame 6 is foldable, retractable, or detachable from the connecting device 5. In this embodiment, the seat frame 6 is preferably detachably connected to the connecting device 5 so that the seat frame 6 can be removed from the connecting device 5 during transportation, thereby reducing the volume during transportation. The outer shell 3 includes a movable shell 31 and a fixed shell 32 which are nested together. The movable shell 31 and the fixed shell 32 form an accommodating cavity. The movable shell 31 and the connecting device 5 are fixed relative to each other, and the fixed shell 32 and the base 2 are fixed relative to each other. The two lifting rod assemblies 4 and at least part of the connecting device 5 are located in the accommodating cavity.

[0041] It should be noted that the number of support legs 1 can also be one, two, three, five, etc., and this embodiment does not limit the number of support legs 1. When the number of support legs 1 is one or two, the structure of the support legs 1 needs to be modified accordingly to meet the support requirements (in this case, the support legs 1 of the shape shown in the embodiment cannot be used). Since the inventive concept of the present invention does not lie in the shape of the support legs 1, no additional examples are given here.

[0042] It should be noted that the number of lift rod assemblies 4 can also be three, four, etc. This embodiment does not impose a limitation on the number of lift rod assemblies 4, and the number of lift rod assemblies 4 can be two or more. In this way, using at least two lift rod assemblies 4 to provide lifting support for the seat frame 6 helps reduce the performance requirements of the lift rod assemblies 4 while ensuring support stability, thereby reducing the overall cost of the lifting structure.

[0043] The baby care equipment provided by the present invention comprises a supporting foot 1 supporting the base 2, the base 2 supporting the lifting rod assembly 4, and the lifting rod assembly 4 supporting the seat frame 6 through a connecting device 5. When the height of the seat frame 6 needs to be adjusted, the movable rod 41 and the fixed rod 42 are unlocked, and the seat frame 6 is lifted up or pressed down to adjust the height. During the height adjustment process, the supporting foot 1, the base 2, the fixed rod 42, and the fixed shell 32 remain stationary, and the movable rod 41, the connecting device 5, the seat frame 6, and the movable shell 31 are lifted and lowered together; when transportation is required, the supporting foot 1 can be removed from the base 2 and the seat frame 6 can be removed from the connecting device 5, and the base 2, the shell 3, the two lifting rod assemblies 4, and the connecting device 5 can be retained as a modular unit, and the supporting foot 1, the seat frame 6, and the modular unit can be packaged and transported separately.

[0044] As needed, the optional seat frame 6 itself can be further contracted, folded, or disassembled to further reduce the volume. This embodiment does not limit the specific structure of the seat frame 6, and the inventive concept of the present invention does not lie in the specific structure of the seat frame 6, so it will not be stated here. The seat frame 6 can adopt any structure.

[0045] In this way, the above-mentioned baby care equipment realizes the relative fixed connection of the fixed rods 42 in the multiple lifting rod assemblies 4 through the base 2, realizes the relative fixed connection of the movable rods 41 in the multiple lifting rod assemblies 4 through the connecting device 5, and uses the movable shell 31 and the fixed shell 32 that can be arranged mutually to cover the lifting rod assembly 4 and at least part of the connecting device 5 in its accommodating cavity, thereby forming a modular unit, which will not be exposed when the lifting rod assembly 4 is raised or lowered, and the modular unit can be set to be very small, beautiful and low in cost, and then connected to the base 2 through the supporting foot 1. It is connected to the connecting device 5 through the seat frame 6, wherein the supporting foot 1 is foldable or retractable or detachable from the base 2, and the seat frame 6 is foldable or retractable or detachable from the connecting device 5. There is no need to disassemble the lifting rod assembly 4 during transportation. It is only necessary to remove the supporting foot 1 from the base 2 and the seat frame 6 from the connecting device 5. This ensures that the support provided by the lifting rod assembly 4 is highly stable and not easy to shake when the infant care equipment is in normal use, and ensures that the overall volume of the infant care equipment can be reduced to a large extent during transportation, thereby greatly improving the overall comprehensive performance of the infant care equipment.

[0046] It should be noted that when the supporting leg 1 adopts a foldable or retractable structure and the seat frame 6 adopts a foldable or retractable structure, during transportation, the size of the reduced volume of the supporting leg 1 and the seat frame 6 is easily affected by the above-mentioned modular unit. Since the volume of the modular unit can be set very small, after the seat frame 6 and the supporting leg 1 are folded or retracted, their overall volume can also be reduced to a large extent, which can also facilitate transportation.

[0047] Of course, during transportation, other methods can be used to reduce the space occupied by the seat frame 6 and the support legs 1 so as to reduce the overall volume of the infant care equipment for transportation.

[0048] See Figure 4 、 Figure 5 and Figure 8 Based on the aforementioned arrangement of two lifting rod assemblies 4, preferably, the arrangement direction of the two lifting rod assemblies 4 is set at an angle to the length direction of the seat frame 6, and the arrangement direction of the two lifting rod assemblies 4 is also set at an angle to the width direction of the seat frame 6. It can also be understood that the two lifting rod assemblies 4 are arranged at diagonal intervals. When an infant lies on the infant care device, they may deviate from the center position of the seat frame 6 due to factors such as turning over, which will cause the center of gravity of the load to shift. The two lifting rod assemblies 4 arranged at diagonal intervals can provide support on both sides along the length direction of the seat frame 6 and along the width direction of the seat frame 6. Compared with an arrangement along the length or width direction of the seat frame 6, the two lifting rod assemblies 4 arranged in this way have better force and are more stable while ensuring the overall cost of the lifting mechanism is low.

[0049] It should be noted that the seat frame 6 of this embodiment is preferably rectangular. Of course, the seat frame 6 can also be elliptical or have arc shapes at both ends of the length of the seat frame 6. Such a seat frame 6 also has a length direction and a width direction.

[0050] See Figure 2 and Figure 4 Preferably, the base 2 is also located in the accommodating cavity, thereby further improving the overall aesthetics of the modular unit. The shielding effect of the fixed shell 32 can also prevent dust, water, etc. from entering the base 2, and can also prevent the structure of the base 2 from cutting the packaging film during transportation packaging.

[0051] See Figure 2 、 Figure 4 and Figure 9 Preferably, to facilitate the installation of the support leg 1 on the base 2, a first slot 24 is provided on the base 2, and a first through-hole 321 is provided on the circumference of the fixing shell corresponding to the position of the first slot 24. Since there are four support legs 1, there are also four first slots 24 and four first through-holes 321. After the support leg 1 passes through the first through-holes 321, it can be detachably inserted into the first slot 24 and a fixed connection can be formed. After the support leg 1 is inserted into the first slot 24, the fixed connection between the support leg 1 and the base 2 can be achieved by screwing, snapping, or locking.

[0052] Specifically, the base 2 includes a first base body 21, a second base body 22, and a fixed connection member 23. The first base body 21 and the second base body 22 are fixedly connected by the fixed connection member 23. Preferably, the fixed connection member 23 is U-shaped, and the first base body 21 is provided with an arc-shaped groove 211 that engages with the fixed connection member 23, and the second base body 22 is provided with two second slots 221 that are plugged into the fixed connection member 23.

[0053] Since there are four first slots 24, two first slots 24 are provided on the first base 21, and two first slots 24 are provided on the second base 22. Furthermore, since there are two lifting rod assemblies 4, third slots 25 are provided on the first base 21 and the second base 22, respectively. The third slots 25 can be used to insert the fixing rod 42. After the fixing rod 42 is inserted into the third slots 25, it can be further secured by attaching screws, snapping, or locking.

[0054] In this way, the fixed connector 23 is used to connect the first base body 21 and the second base body 22, which can ensure the strength of the base 2 and save costs, and the fixed connector 23 is set to a U-shape, which can provide torsional strength. When assembling the base 2, the arcuate portion of the fixed connector 23 can be embedded in the arcuate groove 211 of the first base body 21 and fixed by the attached screws, and the two rod end portions of the fixed connector 23 can be inserted into the second slot 221 of the second base body 22 and fixed by the attached screws, which is convenient for assembly.

[0055] See Figure 4 and Figure 5 In this embodiment, the connecting device 5 includes a connecting portion 51, a mounting seat 52, and a driving mechanism 53. The connecting portion 51 is fixedly connected to at least two movable rods 41, and the driving mechanism 53 is arranged on the connecting portion 51. The connecting portion 51 and the driving mechanism 53 are both located in the movable shell. The output end of the driving mechanism 53 passes through the movable shell and is connected to the mounting seat 52, and the seat frame 6 is connected to the mounting seat 52. In the infant care equipment of the above scheme, in addition to connecting the two movable rods 41, the connecting portion 51 can also provide support for the driving mechanism 53. The driving mechanism 53 supports the mounting seat 52, and the mounting seat 52 in turn supports the seat frame 6. The driving mechanism 53 can be used to drive the mounting seat 52 to move, and the mounting seat 52 will also move with the seat frame 6. In this way, the functionality of the product is further increased, thereby making it more cost-effective and more popular with consumers.

[0056] Since the seat frame 6 is detachably connected to the connecting device 5, the seat frame 6 is detachably connected to the mounting base 52. Figure 3 The mounting seat 52 is provided with a mounting hole 521, and the bottom rod of the seat frame 6 can be inserted into the mounting hole 521 and fixed by attaching screws.

[0057] Of course, in other embodiments, the mounting base 52 and the seat frame 6 may be detachably connected in other ways. The inventive concept of the present invention does not lie in the specific connection method between the mounting base 52 and the seat frame 6, so no further examples are given here.

[0058] See Figure 10 、 Figure 11 and Figure 14 In this embodiment, preferably, the connecting portion 51 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 another movable rod 41, and both ends of the U-shaped tube 513 face upward and are respectively connected to the first connecting member 511 and the second connecting member 512. Specifically, the first connecting member 511 is provided with a first connecting groove (not shown in the figure) and a first plug rod 5112, and the second connecting member 512 is provided with a second connecting groove 5121, a second plug rod 5122, a connecting seat 5123, and a motor cavity 5124. The first plug rod 5112 is inserted from top to bottom into the upper end of one movable rod 41 and can be fixed by an attachment screw. The second plug rod 5122 is inserted from top to bottom into the upper end of another movable rod 41 and can be fixed by an attachment screw. One end of the U-shaped tube 513 is inserted into the first connecting groove The second connecting member 511 and the second connecting member 512 are connected to each other through the U-shaped tube 513. The U-shaped tube 513 is fixed to the second connecting groove 5121 and can be fixed by attaching screws. In this way, the purpose of the connecting part 51 to form a fixed connection between the two movable rods 41 is achieved, and the U-shaped tube 513 is used to connect the first connecting member 511 and the second connecting member 512, which can ensure the strength of the connecting part 51 and save costs. In addition, the U-shaped tube 513 can also be used to provide an avoidance space for the driving mechanism 53 to avoid interference between the driving mechanism 53 and the connecting part 51 when the driving mechanism 53 is in motion.

[0059] Combine Figure 8 and Figure 11Preferably, the driving mechanism 53 includes a swinging portion 531, which is pivotally connected to the connecting portion 51. The mounting seat 52 swings along with the swinging portion 531, causing the seat frame 6 to swing relative to the connecting portion 51, thereby allowing the baby care device to be used as a rocking bed. As a specific example, the driving mechanism 53 also includes a motor 532, and the swinging part 531 includes a swing arm 5311, a rotating shaft 5312, a limiting member 5313, and a limiting slot 5314. One end of the swing arm 5311 swings back and forth relative to the connecting part 51 around the first pivot axis, and the motor 532 is arranged on the connecting part 51 and is used to drive the swing arm 5311 to swing. The rotating shaft 5312 is pivoted to the other end of the swing arm 5311 and swings with the swing arm 5311. One end of the rotating shaft 5312 passes through the movable shell 31 and is fixed to the mounting seat 52, and the other end of the rotating shaft 5312 is fixed to the limiting member 5313. The limiting slot 5314 is arranged on the connecting part 51, and the limiting member 5313 cooperates with the limiting slot 5314. The limiting member 5313 can move relative to the limiting slot 5314 to limit the rotation angle of the rotating shaft 5312 relative to the swing arm 5311. Specifically, the motor 532 is installed on the motor cavity 5124 in the second connecting member 512 , the swing arm 5311 is fixedly connected to the output shaft of the motor 532 , and the limiting groove 5314 is connected to the connecting seat 5123 in the second connecting member 512 .

[0060] In other embodiments, the swing portion 531 may also adopt a non-electric structure, such as using two parallel arranged rotating shafts 5312, with the two ends of the rotating shaft 5312 respectively hinged to the mounting seat 52 and the connecting portion 51, so as to realize manual swinging of the seat frame 6.

[0061] More preferably, based on the aforementioned driving mechanism 53, the limiting groove 5314 is movably arranged relative to the connecting part 51. Specifically, the limiting groove 5314 is hinged above the connecting seat 5123 and also includes a rocking mode adjustment mechanism 9 for adjusting the position of the limiting groove 5314, so that the rocking mode adjustment mechanism 9 can be used to realize a variety of rocking modes of the baby care equipment when the rocking bed is used.

[0062] See Figures 12 to 14As a specific example, the swing mode adjustment mechanism 9 includes a connecting handle 91, a first switch assembly 92, a first transmission member 93, and a first locking and unlocking portion 97. The lower end of the connecting handle 91 is connected to the limiting groove 5314, and the first switch assembly 92 is connected to the upper end of the connecting handle 91. The first switch assembly 92 is located at the upper end of the movable shell 31. In this way, the first switch assembly 92 can be located at a relatively high position by utilizing the function 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 will not interfere with the fixed shell 32, and will not affect the lifting stroke of the seat frame 6. The seat frame 6 can be designed to be lowered lower; the first locking and unlocking portion 97 is arranged between the limiting groove 5314 and the connecting portion 51, and the first transmission member 93 is respectively connected to the first switch assembly 92 and the first locking and unlocking portion 97.

[0063] Specifically, the first locking and unlocking portion 97 includes a locking member 94, a plurality of second locking grooves 95 arranged on the connecting portion 51, and a third reset member 96. The locking member 94 is movably connected to 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. The locking member 94 can be locked with different second locking grooves 95 to adjust the limiting groove 5314 to different positions. The third reset member 96 is arranged between the locking member 94 and the limiting groove 5314 or the third reset member 96 is arranged between the locking member 94 and the connecting handle 91. The function of the third reset member 96 is to drive the locking member 94 to reset so that the locking member 94 is locked with the corresponding second lock 95.

[0064] Of course, in other embodiments, the first locking and unlocking portion 97 may not be provided with a reset member, but a reset member may be provided in the first switch assembly 92 to indirectly drive the locking member 94 to reset.

[0065] In this embodiment, preferably, the first switch assembly 92 is movably connected to the upper end of the connecting handle 91. The first switch assembly 92 is also movably connected to the connecting portion 51. After the first switch assembly 92 drives the first locking and unlocking portion 97 to unlock via the first transmission member 93, the first switch assembly 92 can be driven to move relative to the connecting portion 51, so that the first switch assembly 92 drives the connecting handle 91, causing the connecting handle 91 to move relative to the connecting portion 51 with the limiting groove 5314, thereby adjusting the position of the limiting groove 5314. Preferably, the first switch assembly 92 is slidably connected to the connecting portion 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 relative to the upper end of the connecting handle 91 (such as linear sliding or arc sliding), causing the limiting groove 5314 to rotate relative to the connecting portion 51. In this way, the sliding movement of the first switch assembly 92 can be converted into a rotational movement of the connecting handle 91, so that the connecting handle 91 drives the limiting groove 5314 to rotate, thereby adjusting the position of the limiting groove 5314.

[0066] Specifically, the connecting portion 51 includes a switch box 5111, and the special switch box 5111 is installed on the first connecting member 511. The first switch assembly 92 includes a switch connecting member 921, a sleeve 922, an adapter 923, and a first switch 924. The adapter 923 is hinged to the upper end of the connecting handle 91. The sleeve 922 relatively restricts 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 slidingly connected to the switch connecting member 921, and the switch connecting member 921 is slidingly connected to the switch box 5111. The first switch 924 is hinged to the switch connecting member 921. The first switch 924 is connected to the first transmission member 93. The upper end of the movable shell 311 is provided with an avoidance groove 315 for exposing the first switch 924. Among them, the first transmission member 93 is preferably a cable, the first switch 924 is connected to one end of the first transmission member 93, one end of the locking member 94 is hinged below the limiting groove 5314, and the other end of the locking member 94 is connected to the other end of the first transmission member 93, the third reset member 96 is preferably a spring, and the second locking groove 95 is specifically arranged on the second connecting member 512, and multiple second locking grooves 95 are arranged in a circular arc along the rotating axis 5312 line between the limiting groove 5314 and the connecting seat 5123. When the position of the limit slot 5314 needs to be adjusted, the first switch 924 is rotated, and the first switch 924 drives the lock member 94 to rotate upward through the first transmission member 93, so that the lock member 94 compresses the third reset member 96 and the lock member 94 is disengaged from the corresponding second lock slot 95 to complete the unlocking. Then, the first switch 924 is pushed to push the first switch 924 and the switch connector 921 to slide relative to the switch box 5111. The switch connector 921 drives the connecting handle 91 through the adapter 923, wherein the connecting handle 91 and the adapter 923 generate relative rotation and transfer. The member 923 and the switch connecting member 921 slide relative to each other, causing the connecting handle 91 to rotate relative to the connecting seat 5123 with the limiting groove 5314 until the locking member 94 is aligned with the second locking groove 95 of the new target, and then the first switch 924 is released. The locking member 94 is inserted into the second locking groove 95 under the drive of the third reset member 96 to complete the locking. Among them, since the connecting handle 91 and the adapter 923 rotate relative to each other, and the adapter 923 and the switch connecting member 921 slide relative to each other, interference between the first switch assembly 92 and the connecting handle 91 can be avoided during adjustment.

[0067] See Figure 3 、 Figures 5 to 7, based on that the driving mechanism 53 can drive the seat frame 6 to move, in order to make the seat frame 6 have an active state and a fixed state, it is preferably also included. The first locking and unlocking mechanism 8 is used to lock or unlock between the mounting seat 52 and the connecting part 51. When the first locking and unlocking mechanism 8 locks the mounting seat 52 and the connecting part 51, it prevents the driving mechanism 53 from driving the seat frame 6 to move. In this way, the function of the product is further increased, thereby making it more cost-effective and more popular with consumers.

[0068] As a specific example, the first locking and unlocking mechanism 8 includes a rotating member 81, a locking block 82, and a first resetting member 83. The rotating member 81 is pivotally connected to the mounting seat 52, and also includes an insert block 84 and a fourth slot 85 that are plugged in together. The rotating member 81 is provided with an insert block 84, and the connecting portion 51 is provided with a fourth slot 85. The locking block 82 is movably provided on the rotating member 81. The first resetting member 83 is provided between the rotating member 81 and the locking block 82, and also includes a first locking tongue 86 and a first locking groove 87 that are plugged in together. The locking block 82 is provided with a first locking tongue 86, and the connecting portion 51 is provided with a first locking groove 87. When the first locking tongue 86 is plugged in with the first locking groove 87, the insert block 84 is restricted in the fourth slot 85, thereby preventing the driving mechanism 53 from driving the seat frame 6 to move. Specifically, the fourth slot 85 and the first locking slot 87 are both provided on the upper surface of the first connecting member 511. A pre-tightening force can be generated between the rotating member 81 and the mounting seat 52 by adding a rubber pad or interference fit, so that after applying an external force to rotate the rotating member 81, the rotating member 81 and the mounting seat 52 can be relatively positioned, or a torsion spring or other structure can be provided between the rotating member 81 and the mounting seat 52 to keep the rotating member 81 rotating upward and returning to its original position; the locking block 82 is slidably provided on the rotating member 81, and the two locking blocks 82 are connected by a cross bar. The first locking slot 87 is located on the inner side of the fourth slot 85 On the wall, the first reset member 83 is preferably a spring. When the rotating member 81 rotates downward to insert the insert block 84 into the fourth slot 85, the fourth slot 85 can push the first locking tongue 86 to make the locking block 82 slide and compress the first reset member 83. Of course, the cross bar can also be manually driven to drive the locking block 82 to slide and compress the first reset member 83 until the first locking tongue 86 is aligned with the first locking groove 87. Under the action of the first reset member 83, the first locking tongue 86 can be inserted into the first locking groove 87, thereby restricting the insert block 84 in the fourth slot 85, thereby preventing the driving mechanism 53 from driving the seat frame 6 to move.

[0069] Of course, the setting objects of the plug block 84 and the fourth slot 85 can also be interchanged, that is, the plug block 84 can be set on the connecting part 51, and the fourth slot 85 can be correspondingly set on the rotating part 81; similarly, the setting objects of the first lock tongue 86 and the first lock groove 87 can also be interchanged, that is, the first lock tongue 86 can be set on the connecting part 51, and the first lock groove 87 can be correspondingly set on the lock block 82.

[0070] See Figure 8 、 Figure 10 、 Figure 11 and Figure 14 In this embodiment, a reinforcing mechanism 7 is further included within the accommodating cavity. The reinforcing mechanism 7 is connected to the connecting device 5 and can be raised or lowered along with the connecting device 5. The reinforcing mechanism 7 can be used to support the inner sidewall of the movable shell 31 or the inner sidewall of the fixed shell 32. In this way, the reinforcing mechanism 7 provides support for the outer shell 3, preventing deformation of the outer shell 3 caused by lateral impact or extrusion during transportation.

[0071] 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 the outer shell 3 is subjected to impact or extrusion, resulting in a small amount of deformation, the reinforcing mechanism 7 then 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 maintain a certain gap with the inner side wall of the movable shell 31 or the inner side wall of the fixed shell 32, and the gap is eliminated when a small amount of deformation occurs in the outer shell 3, so that the reinforcing mechanism 7 forms a supporting role.

[0072] Specifically, the reinforcement mechanism 7 includes a reinforcement sleeve 71 connected to the connecting device 5. The circumferential side walls of the reinforcement sleeve 71 can be used to slide against the inner side wall of the movable shell 31 or against the inner wall of the fixed shell 32. During installation, the reinforcement sleeve 71 can be positioned at the lower open end of the movable shell 31 or at the upper open end of the fixed shell 32, thereby utilizing the reinforcement sleeve 71 to provide more comprehensive support for the outer shell 3. Similarly, the circumferential side walls of the reinforcement sleeve 71 can directly abut against the inner side wall of the movable shell 31 or against the inner side wall of the fixed shell 32, thereby forming direct support; alternatively, the circumferential side walls of the reinforcement sleeve 71 can maintain a removable gap with the inner side wall of the movable shell 31 or against the inner side wall of the fixed shell 32, thereby providing support after a small amount of deformation of the outer shell 3.

[0073] For ease of understanding, in this embodiment, preferably, the movable shell 31 is arranged outside the fixed shell 32, so as to prevent water or dust from entering the accommodating cavity through the gap between the movable shell 31 and the fixed shell 32. At this time, the circumferential side wall of the reinforcement sleeve 71 will slide against the inner wall of the fixed shell 32, and the reinforcement sleeve 71 first provides a supporting force to act on the fixed shell 32, and then uses the fixed shell 32 to indirectly provide a supporting force to act on the movable shell 31, thereby forming an overall support for the outer shell 3.

[0074] Of course, in other examples, when the fixed shell 32 is arranged outside the movable shell 31, the circumferential side wall of the reinforcement sleeve 71 will slide against the inner side wall of the movable shell 31 accordingly, and the reinforcement sleeve 71 first provides a supporting force to the movable shell 31, and then uses the movable shell 31 to indirectly provide a supporting force to the fixed shell 32, thereby forming an overall support for the outer shell 3.

[0075] Preferably, a second through hole 711 is provided on the reinforcing sleeve 71 for the fixed rod 42 and / or the movable rod 41 to pass through. In this way, the reinforcing sleeve 71 can make use of the function of the fixed rod 42 or the movable rod 41 to make the reinforcing sleeve 71 less likely to deform and provide better support. At the same time, the reinforcing sleeve 71 can also reversely limit the torsion of the fixed rod 42 or the movable rod 41, making the seat frame 6 more stable.

[0076] More preferably, in order to allow the seat frame 6 to be lowered lower, the reinforcement sleeve 71 is slid on the connecting device 5 according to a preset stroke, and the reinforcement mechanism 7 also includes a second reset member 72, which is connected between the reinforcement sleeve 71 and the connecting device 5. When the reinforcement sleeve 71 is lowered to a low position along with the connecting device 5 so that the reinforcement sleeve 71 is against the base 2, the base 2 can push the reinforcement sleeve 71 to compress the second reset member 72. When the cam 72 is in the unlock position, the locking cam 73 is in the unlock position, and the locking cam 73 is in the unlock position, so that the cam 73 is locked and the locking cam 73 is locked.

[0077] Specifically, based on the structure of the aforementioned connecting device 5, the connecting part 51 also includes a connecting plate 518 and a fixing sleeve 519, wherein the connecting plate 518 is connected to the bottom of the connecting seat 5123 in the first connecting member 511, and the fixing sleeve 519 is connected to the bottom of the connecting plate 518. The reinforcing sleeve 71 is slidably sleeved outside the fixing sleeve 519, and the reinforcing sleeve 71 can slide up and down relative to the fixing sleeve 519. Moreover, a limiting structure such as a step matching structure or a limiting block can be provided between the reinforcing sleeve 71 and the fixing sleeve 519 to limit the reinforcing sleeve 71 from detaching from the fixing sleeve 519. The second reset member 72 is preferably a spring, and the upper end of the second reset member 72 abuts against the bottom of the connecting plate 518, and the upper end of the second reset member 72 abuts against the top of the reinforcing sleeve 71.

[0078] See Figure 5 、 Figure 8 、 Figures 15 to 22 In this embodiment, the second locking and unlocking mechanism 43 includes 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 to the second locking and unlocking portion 431, and the other end of the second transmission member 432 is connected to the second switch assembly 433. The second switch assembly 433 is arranged on the connecting device 5. Specifically, the second switch assembly 433 of one lifting rod assembly 4 is arranged on the first connecting member 511, and the other lifting rod assembly 4 is arranged on the first connecting member 511. The second switch assembly 433 of a lifting rod assembly 4 is disposed on the second connecting member 512. Compared to disposing the second switch assembly 433 on the housing 3, using the connecting device 5 (specifically, the first connecting member 511 or the second connecting member 512) to mount and support the second switch assembly 433 allows the second switch assembly 433 to be positioned higher. This does not affect the raising and lowering of the lifting assembly, allowing the seat frame to be lowered. Compared to disposing the second switch assembly 433 on the seat frame 6, this solution is less expensive and more aesthetically pleasing. Preferably, the second transmission member 432 is a cable.

[0079] See Figure 18 and Figure 19, taking the second switch assembly 433 being provided on the first connecting member 511 as an example, as a specific example, the second switch assembly 433 includes a protective handle 4331, a second switch 4332, a first slider 4333, a second slider 4334, and a fifth reset member 4335. The first connecting member 511 is provided with a first sliding groove 514 that slides with the first slider 4333, a second sliding groove 515 that slides with the second slider 4334, and an accommodating groove 516 for accommodating the rotation and retraction of the protective handle 4331. The protective handle 4331 and the second switch 4332 are coaxially rotatable around the rotating shaft 517 on the first connecting member 511 and are arranged in the accommodating groove 516. The fifth reset member 4335 is provided between the protective handle 4331 and the second switch 4332. The second switch 4332 can be used to drive the first slider 43 The first slider 4333 can be used to drive the second slider 4334 to slide. The second slider 4334 is connected to the other end of the second transmission member 432. The protective handle 4331 has an open state and a retracted state. When the protective handle 4331 is in the open state, the protective handle 4331 drives the second switch 4332 to rotate outward and expose it. At this time, the second switch 4332 can be operated and the second locking and unlocking part 431 is driven by the second transmission member 432, so that the second locking and unlocking part 431 releases the lock on the movable rod 41 and the fixed rod 42. When the protective handle 4331 is in the retracted state, the protective handle 4331 drives the second switch 4332 to rotate inward and hide it, thereby preventing the second switch 4332 from being operated, so that the second locking and unlocking part 431 remains locked and prevents the movable rod 41 and the fixed rod 42 from being raised or lowered. In this way, when the protective handle 4331 is retracted, it can be stored in the receiving slot 516 with the second switch 4332, reducing the packaging space, making the packaged volume smaller, and the appearance more beautiful.

[0080] Specifically, the protective handle 4331 is provided with an abutment groove 43311, the second switch 4332 is provided with a spring abutment piece 43321 and a first shift block 43322, the first slider 4333 is provided with a second shift block 43331 and a second inclined groove 43332, the second slider 4334 is provided with a second protrusion 43341, 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 abutment groove 43311, the spring abutment piece 43321 is located in the abutment groove 43311 and can rotate relatively in the abutment groove 43311, and the rear side wall of the abutment groove 43311 can abut against the spring abutment piece 43321, so that when the protective handle 4331 is rotated outward to open, it can be driven by the abutment cooperation between the abutment groove 43311 and the spring abutment piece 43321. The second switch 4332 is rotated outward to be exposed, and the second protrusion 43341 is inserted into the second oblique groove 43332 and can slide on the second oblique groove 43332. The first selector block 43322 can push the second selector block 43331 when the second switch 4332 is rotated to a certain angle, thereby causing the first slider 4333 to slide (the specific condition is: after the protective handle 4331 drives the second switch 4332 to rotate outward to be exposed, and then presses the second switch 4332 to rotate). The sliding of the first slider 4333 can drive the second slider 4334 to slide under the cooperation of the second protrusion and the second oblique groove 43332, and then drive the second transmission member 432 through the second slider 4334, and the second transmission member 432 then acts on the second locking and unlocking portion 431, so that the movable rod 41 and the fixed rod 42 are unlocked.

[0081] Combine Figures 20 to 22 For ease of understanding, the specific operation process of the second switch component 433 is as follows: Figure 20 The schematic diagram of the protective handle 4331 in the folded state is shown. At this time, the protective handle 4331 is rotated to make it enter the open state from the folded state. During this process, the rear side wall of the abutment groove 43311 pushes the spring abutment piece 43321, so that the second switch 4332 can rotate along with the protective handle 4331, so that the second switch 4332 rotates outward and is exposed. Although the first dial block 43322 rotates along with the second switch 4332, the first dial block 43322 has not yet abutted against the second dial block 43331, that is, the first slider 4333 and the second slider 4334 remain stationary, and the protective handle 4331 is opened. Figure 21The protective handle 4331 is shown in a schematic diagram in an open state. Since the second switch 4332 is exposed, the second switch 4332 can be pressed at this time. In the process of pressing the second switch 4332, the second switch 4332 rotates a second time to compress the fifth reset member 4335, and the first dial block 43322 gradually begins to push the second dial block 43331, causing the first slider 4333 to slide. The first slider 4333 drives the second slider 4334 to slide under the cooperation of the second protrusion and the second inclined groove 43332. When the second slider 4334 slides, it can drive the second locking and unlocking part 431 through the second transmission member 432 to release the lock on the movable rod 41 and the fixed rod 42, completing the unlocking and entering. Figure 22 Schematic diagram of pressing the second switch 4332 is shown.

[0082] 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 a first sliding groove 514, a second sliding groove 515, and a receiving groove 516. The specific installation method and switching action of the second switch assembly 433 on the second connecting member 512 can be referred to the above description and will not be repeated here.

[0083] Of course, in other examples, the driving cooperation between the second switch 4332 and the second transmission member 432 can also be other ways, such as: there is no first slider 4333 and the second slider 4334, the second switch 4332 is connected to 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 applies a pulling force to the second transmission member 432, so that the second locking and unlocking portion 431 is driven by the second transmission member 432 to release the lock of the movable rod 41 and the fixed rod 42, and the unlocking is completed. At this time, the cable protection cover of the second transmission member 432 can be installed on the protective handle 4331, so that when the protective handle 4331 carries the second switch 43 32 are rotated to open or close together (that is, when the second switch 4332 is not pressed 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 a first slider 4333 but no second slider 4334. At this time, the first slider 4333 is connected to 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 slider 4333 to slide, and the first slider 4333 applies a pulling force to the second transmission member 432, thereby driving the second locking and unlocking portion 431 through the second transmission member 432 to release the lock on the movable rod 41 and the fixed rod 42, thereby completing the unlocking.

[0084] In comparison, the advantage of combining the first slider 4333 and the second slider 4334 in this embodiment is that during the rotation and opening and closing of the protective handle 4331, there is no need to move the second transmission member 432 together, and the arrangement of the second transmission member 432 can be simpler, reducing bending and friction, making the switch operation smoother.

[0085] It should be noted that the present invention does not limit the specific structure of the second locking and unlocking portion 431, and any structure that can achieve locking or unlocking of the movable rod 41 and the fixed rod 42 can be used. For ease of understanding, the second locking and unlocking portion 431 can adopt the following structure: See Figures 15 to 17 The lower end of the movable rod 41 is provided with a lower block 411, and the upper end of the fixed rod 42 is provided with an upper block 421.

The side wall of the fixed rod 42 is also provided with a plurality of lock holes 422 arranged in the vertical direction. The second locking and unlocking part 431 includes a lifting lock block 4311, a lifting slider 4312, and a fourth reset member 4313. The lifting lock block 4311 is horizontally slidably arranged on the lower block 411, the lifting lock block 4311 can be plugged into the lock hole 422, the lifting slider 4312 is vertically slidably arranged on the lower block 411, a first protrusion 43111 is provided on one side of the lifting lock block 4311, and a first inclined groove 43121 is provided on the lifting slider 4312, the first protrusion 43111 and the first inclined groove 43121 cooperate, and the fourth reset member 4313 is preferably a spring and is provided on the lower block 411 and When the second switch assembly 433 is released, the lifting slider 4312 slides downward and is reset under the elastic force of the fourth restoring member 4313, and the lifting slider 4312 drives the lifting lock block 4311 to slide in the opposite direction under the cooperation of the first protrusion 43111 and the first inclined groove 43121, so that the lifting lock block 4311 is disengaged from the lock hole 422 and is unlocked. At this time, the movable rod 41 can be lifted and lowered relative to the fixed rod 42. When the second switch assembly 433 is released, the lifting slider 4312 slides downward and is reset under the elastic force of the fourth restoring member 4313, and the lifting slider 4312 drives the lifting lock block 4311 to slide in the opposite direction 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 lock hole 422 and is locked.
