Description

Technical Field

[0001] This utility model relates to the field of children's rocking chair technology, specifically a children's rocking chair with a shock-absorbing support structure. Background Technology

[0002] When parents place a child in a rocking chair, the child's movements will cause the weighted vehicle to sway, and the rocking chair is very useful for diverting the baby's attention, thus reducing the parents' energy expenditure.

[0003] While existing children's rocking chairs can distract children by generating rocking motions, the weight-bearing structure of these chairs is also affected by the lateral swaying motions during deformation and shaking, reducing the child's comfort. Consequently, children may become unwilling to continue lying on the weight-bearing structure after a long period of time, thus reducing the practicality of existing children's rocking chairs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a children's rocking chair with a shock-absorbing support structure, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: A children's rocking chair with a shock-absorbing support structure, including a base, a sleeve fixedly mounted on the top of the base, a support strip fixedly mounted on the outer wall of the base, a powerful motor fixedly mounted on the top of the sleeve, an electromagnetic brake on the output shaft of the powerful motor, a lead screw fixedly mounted on the output shaft of the powerful motor, a lifting plate threadedly connected to the outer wall of the lead screw, a support rod fixedly mounted on the top of the lifting plate, a connecting platform fixedly mounted on the top of the support rod, a carrier fixedly mounted on the top of the connecting platform, a stop block fixedly mounted on the outer wall of the carrier, an installation cylinder on the top of the base, a limit rod fixedly mounted on the inner wall of the installation cylinder, a shock-absorbing spring sleeved on the outer wall of the limit rod, the top of the shock-absorbing spring abutting against a limit ring, a sliding rod on the top of the limit ring, a connecting ring fixedly mounted on the top of the sliding rod, and a limit groove formed on the inner wall of the sleeve.

[0006] In a preferred embodiment of this invention, the inner wall of the connecting ring is slidably sleeved with the outer wall of the carrier, and the outer wall of the stop block overlaps with the outer wall of the connecting ring.

[0007] As a preferred embodiment of this utility model, the number of the stops is two, and both stops are symmetrically distributed along the outer wall of the vehicle.

[0008] As a preferred embodiment of this utility model, a positioning platform is fixedly assembled on the top of the base, and the top of the positioning platform is fixedly assembled with the bottom of the mounting cylinder.

[0009] As a preferred technical solution of this utility model, the bottom ends of the limiting ring and the sliding rod are both provided with limiting holes, and the inner wall of the limiting hole is slidably connected to the outer wall of the limiting rod.

[0010] As a preferred technical solution of this utility model, the outer wall of the limiting ring is slidably connected to the inner wall of the mounting cylinder, and both the limiting ring and the sliding rod are made of galvanized iron metal.

[0011] As a preferred embodiment of this utility model, the outer wall of the lifting plate is fixedly fitted with a protrusion, and the outer wall of the protrusion is slidably connected to the inner wall of the limiting groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This children's rocking chair with a shock-absorbing support structure, through its base, mounting cylinder, connecting ring, slide rod, shock-absorbing spring, and limiting ring structure, allows the rocking chair to deform under the influence of reaction force during use. The connecting ring applies pressure to the slide rod, causing both the slide rod and the limiting ring to move downwards along the outer wall of the limiting rod, compressing the shock-absorbing spring. This limits the movement of the rocking chair and counteracts the vibration force, preventing the chair from tilting. Consequently, it improves the comfort of children during rocking, as well as the stability and safety of the rocking chair under load.

[0014] 2. This children's rocking chair with shock-absorbing support structure, through the setting of a powerful motor, lead screw, connecting platform, carrier, electromagnetic brake, and limit groove structure, allows the user to slide the lifting plate along the inner wall of the sleeve during use by operating the powerful motor, thereby automatically adjusting the height of the carrier. This makes it easier for the user to operate and allows children of different heights to use the children's rocking chair, thus increasing the scope of use of the children's rocking chair.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 A children's rocking chair with a shock-absorbing support structure includes a base 1, a sleeve 2 fixedly mounted on the top of the base 1, a support bar 3 fixedly mounted on the outer wall of the base 1, a powerful motor 4 fixedly mounted on the top of the sleeve 2, an electromagnetic brake 17 on the output shaft of the powerful motor 4, a lead screw 11 fixedly mounted on the output shaft of the powerful motor 4, a lifting plate 12 threadedly connected to the outer wall of the lead screw 11, a support rod 10 fixedly mounted on the top of the lifting plate 12, a connecting platform 5 fixedly mounted on the top of the support rod 10, a carrier 6 fixedly mounted on the top of the connecting platform 5, a stop block 15 fixedly mounted on the outer wall of the carrier 6, an installation cylinder 7 on the top of the base 1, a limit rod 16 fixedly mounted on the inner wall of the installation cylinder 7, a shock-absorbing spring 13 sleeved on the outer wall of the limit rod 16, a limit ring 14 abutting the top of the shock-absorbing spring 13, a sliding rod 8 on the top of the limit ring 14, a connecting ring 9 fixedly mounted on the top of the sliding rod 8, and a limit groove 18 formed on the inner wall of the sleeve 2.

[0023] In the above structure, the base 1, sleeve 2, support bar 3, carrier 6, mounting cylinder 7, slide bar 8, connecting ring 9, lead screw 11, lifting plate 12, shock-absorbing spring 13, limiting ring 14, and stop block 15 are designed so that when a child sits on the carrier 6 and rocks back and forth during use, the carrier 6 will deform and cause the child to feel the rocking. At this time, the connecting ring 9 and slide bar 8 can compress the shock-absorbing spring 13 to support and limit the carrier 6, thereby preventing the carrier 6 from swaying left and right during rocking, thus preventing excessive pressure on the child's back and improving the child's comfort.

[0024] In a preferred embodiment, the inner wall of the connecting ring 9 is slidably sleeved with the outer wall of the carrier 6, and the outer wall of the stop 15 overlaps with the outer wall of the connecting ring 9.

[0025] In the above structure, the carrier 6 and connecting ring 9 are designed so that when the carrier 6 deforms due to external interference, the connecting ring 9 will also be compressed and exert pressure on the slide rod 8. This allows the limiting ring 14 to move downward and compress the shock-absorbing spring 13, thus ensuring that the compression of the shock-absorbing spring 13 allows the carrier 6 to continue to deform and make the child feel the shaking. The stop block 15 can limit the connecting ring 9, preventing the connecting ring 9 from continuously moving towards the end of the carrier 6 closer to the base 1, preventing the mechanism from jamming, and also preventing the connecting ring 9 from continuously sliding and generating tension on the mounting cylinder 7, causing the connection between the mounting cylinder 7 and the base 1 to break. This extends the service life of the children's rocking chair and ensures that the subsequent use of the children's rocking chair will not be affected.

[0026] In a preferred embodiment, there are two blocks 15, and both blocks 15 are symmetrically distributed along the outer wall of the vehicle 6.

[0027] In the above structure, the two stop blocks 15 are designed to limit the movement of both connecting rings 9, ensuring that the connecting rings 9 do not exceed the limits specified by the stop blocks 15 during the reset process. This ensures that the subsequent use of the children's rocking chair will not be affected. The two connecting rings 9 also ensure that both ends of the carrier 6 are limited and will not tilt to the left or right, thereby improving the stability of the carrier 6.

[0028] In a preferred embodiment, a positioning platform is fixedly mounted on the top of the base 1, and the top of the positioning platform is fixedly mounted to the bottom of the mounting cylinder 7.

[0029] In the above structure, the mounting cylinder 7 and the positioning platform are used to fix the mounting cylinder 7, so that when the carrier 6 deforms, the sliding rod 8 can slide along the inner wall of the mounting cylinder 7, and the limiting ring 14 will slide along the outer wall of the limiting rod 16 to compress the shock-absorbing spring 13, thereby achieving the effect of canceling and damping the vibration force. At the same time, the two ends of the carrier 6 are limited to prevent the carrier 6 from tilting, so that the connecting ring 9, the carrier 6 and the connecting platform 5 are connected, further improving the stability of the carrier 6.

[0030] In a preferred embodiment, both the bottom ends of the limiting ring 14 and the slide rod 8 are provided with limiting holes, and the inner wall of the limiting hole is slidably connected to the outer wall of the limiting rod 16.

[0031] In the above structure, the limiting hole structure allows the limiting ring 14 and the sliding rod 8 to slide along the outer wall of the limiting rod 16 when the sliding rod 8 is compressed, thus forming a damping structure based on the damper principle, which in turn makes the children's rocking chair have a better shock absorption effect.

[0032] In a preferred embodiment, the outer wall of the limiting ring 14 is slidably connected to the inner wall of the mounting cylinder 7, and both the limiting ring 14 and the slide rod 8 are made of galvanized iron.

[0033] In the above structure, galvanized iron has the characteristics of hardness and wear resistance, which can effectively reduce the wear of both during operation and thus extend their service life. At the same time, galvanized iron also has the characteristic of low cost, thereby reducing the production and maintenance costs of the children's rocking chair.

[0034] In a preferred embodiment, a protrusion is fixedly mounted on the outer wall of the lifting plate 12, and the outer wall of the protrusion is slidably connected to the inner wall of the limiting groove 18.

[0035] In the above structure, the protrusion and limiting groove 18 structure can limit the lifting plate 12 during the rotation of the lead screw 11, thereby preventing the lifting plate 12 from rotating with the lead screw 11. This achieves the effect that the lifting plate 12 can only be raised and lowered, which makes it easier for the user to adjust the height of the carrier 6 so that the children's rocking chair can be used by children of different heights, thus improving the range of use of the children's rocking chair.

[0036] Working principle: First, the user can rotate the lead screw 11 by operating the powerful motor 4. At this time, the lifting plate 12 cannot rotate with the lead screw 11 under the limiting action of the convex block, so that the lifting plate 12 moves up and down along the inner wall of the sleeve 2, thereby achieving the effect of adjusting the height of the carrier 6. This ensures that children of different heights can use the children's rocking chair, thus increasing the usability of the children's rocking chair. After adjustment, the child can sit on the carrier 6. The child's limb movements generate a reaction force on the carrier 6, causing the carrier 6 to deform, thus allowing the child to feel the rocking effect. During the deformation of the carrier 6, the connecting ring 9 will apply pressure to the sliding rod 8, so that the limiting ring 14 and the sliding rod 8 slide along the outer wall of the limiting rod 16 and compress the shock-absorbing spring 13, thereby achieving the effect of damping the left and right swaying force, preventing the carrier 6 from tilting, and thus improving the comfort of the child.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
