Abstract
Description
Technical Field
[0001] The present disclosure relates to a child carrier, and particularly to a lateral rotation positioning mechanism that can rotate laterally for positioning and a child carrier having the same.
Background Art
[0002] Currently, child seats that can rotate in the front-rear direction in the market can generally be rotated forward or backward. When the carrier is in a state of rotating forward or backward, the seat is locked by a locking mechanism, and the child can sit facing forward or backward. When the child gets off the vehicle or is taken out of the vehicle, the child will face the vehicle door. However, most child seats do not have a temporary positioning function when rotated laterally. Therefore, when getting off the vehicle, the seat is likely to sway or rotate. As a result, it has an adverse effect on the boarding and alighting of children, making it inconvenient to board and alight, easy to fall, and having a safety problem.
Summary of the Invention
[0003] An object of the present disclosure is to provide a lateral rotation positioning mechanism that can position the carrier when the carrier is rotated laterally, has a simple structure, and can improve the convenience and safety of using the child carrier.
[0004] Another object of the present disclosure is to provide a child carrier that can be positioned when the carrier is rotated laterally and can be used conveniently and safely.
[0005] To achieve the above objective, the lateral rotation positioning mechanism provided in this disclosure is a lateral rotation positioning mechanism provided between a base and a body on which the base is rotatably mounted, the lateral rotation positioning mechanism includes an engagement pin and an engagement recess, the engagement pin being extendable and retractable on the body, the engagement recess being provided on the bottom surface of the base and located on at least one side of the base in the lateral direction, and when the base rotates laterally with respect to the body, the engagement pin is inserted into the engagement recess to restrict the rotation of the base.
[0006] Compared to prior art, the engaging pin is provided on the main body, and the engaging recess is provided on the bottom surface of the base, with the engaging recess located on at least one side of the base in the lateral direction. Therefore, when the base is rotated laterally relative to the main body, the engaging pin is inserted into the engaging recess, thereby restricting the rotation of the base and stabilizing it laterally. This makes it convenient to put children in and take them out of the carrier body, improving usability and satisfaction. Furthermore, it prevents the carrier body from rotating during use, preventing children from falling and ensuring safety during use. In addition, the base can only be unlocked by disengaging the engaging pin from the engaging recess. Specifically, the engaging pin can be disengaged from the engaging recess by directly rotating the carrier body, providing good usability and a pleasant user experience.
[0007] In one embodiment, the lateral rotation positioning mechanism also includes an elastic recovery element provided between the body and the engagement pin, which pushes the engagement pin into the engagement recess. The elastic recovery element is used to allow the engagement pin to automatically be inserted into the engagement recess, thereby automatically locking when the base rotates laterally, effectively improving ease of use.
[0008] In one embodiment, a coaxial annular guide groove is provided on the bottom surface of the base, and the engagement recess is provided within the annular guide groove. The annular guide groove slidably contacts the engagement pin, guiding the base to rotate and precisely guiding the engagement pin to slide within the engagement recess, thereby improving the smoothness of rotation and the accuracy of lateral positioning by the pin.
[0009] In one embodiment, the lateral rotation positioning mechanism further includes a positioning block, which is provided on the bottom surface of a base and has an engaging recess. Since the base is made of plastic material and has poor wear resistance, and the engaging recess is provided directly on the base and is prone to material wear, the positioning block can reduce the rate and degree of wear of the engaging recess and extend its service life. Furthermore, even if wear occurs, it can be replaced quickly and easily.
[0010] Specifically, mounting portions are provided at both ends of the positioning block, and these mounting portions are connected to the bottom surface of the base.
[0011] Specifically, a mounting groove is placed on the bottom surface of the base, and the mounting part is embedded in the mounting groove. The combination of the mounting groove and the mounting part allows the positioning block to be assembled to the base accurately and quickly, improving the convenience of assembly and maintenance.
[0012] Specifically, the mounting portion and the base are connected by screw connection, bolt connection, snap connection, adhesive, or welding.
[0013] Specifically, the positioning block is a wear-resistant positioning block and is made of a wear-resistant material.
[0014] In one embodiment, guide slopes are provided on both sides of the engagement recess to guide the engagement pin into or out of the engagement recess. By providing guide slopes, the guide slopes can guide the engagement pin, and therefore, when the base is rotated, the guide slopes can be used to forcibly move the engagement pin out of the engagement recess, thereby achieving the objective of rapid unlocking and improving the convenience of operation.
[0015] A child carrier comprising a carrier body, a base, a main body, and a lateral rotation positioning mechanism, wherein the carrier body is provided on the base, and the base is rotatably provided on the main body around its central axis.
[0016] In one embodiment, a locking hole is provided on the bottom surface of the base, located on the front or rear side of the base. When the base is rotated rearward or forward relative to the main body, the engaging pin is inserted into the locking hole to restrict the rotation of the base. Furthermore, because the locking hole is located on the front or rear side of the base, when the base is positioned rearward or forward, the engaging pin can lock the base in that position, ensuring safety during use.
[0017] Specifically, the base is equipped with a release mechanism that drives the engagement pin out of the locking hole. By providing this release mechanism, the base can be unlocked quickly, improving ease of operation.
[0018] Specifically, the unlocking mechanism includes a slider that is slidably mounted on the base to push the engaging pin out of the locking hole.
[0019] Specifically, the unlocking mechanism further includes a drive element, the middle of which is rotatably connected to a base, one end of which is connected to a slider, and the other end of which moves the slider when driven.
[0020] Specifically, the unlocking mechanism further includes an elastic element provided between the base and the slider to restore the slider. By providing the elastic element, the slider can be automatically separated from the engaging pin, so that the engaging pin can be automatically locked, and accidental pushing-in of the engaging pin can be avoided, thereby improving the safety of operation.
[0021] Specifically, the unlocking mechanism is slidably provided on the side surface of the base and further includes an operating element connected to the other end of the driving element. The operating element is provided outside the base, which is convenient for the user's operation and improves the convenience of use.
[0022] Specifically, the unlocking mechanism further includes a restoring element provided between the base and the operating element to restore the operating element. By providing the restoring element, the operating element can be automatically restored, and the operation effect each time can be improved.

[0036] In order to explain in detail the technical content, structural features, and effects achieved in this disclosure, a detailed description will be provided in conjunction with embodiments and drawings.
[0037] Figures 1 to 8 show the structure of the child carrier 100 in the embodiments of this disclosure.
[0038] Referring to Figures 1 to 4, the child carrier 100 of this disclosure includes a carrier body 1, a base 2, a body 3, and a lateral rotation positioning mechanism 4. The carrier body 1 is provided on the base 2. The body 3 has a cavity 31, and the base 2 is rotatably mounted on the body 3 about its central axis and covers the cavity 31. The lateral rotation positioning mechanism 4 is provided between the base 2 and the body 3 and positions the base 2 in a lateral direction.
[0039] When the child carrier 100 is used in the forward or backward direction, the longitudinal axis of the base 2 of the child carrier 100 is parallel to the longitudinal axis of the main body 3. When the child carrier 1 is used in the lateral direction, that is, when it is "provided to face the lateral direction" as described above, the longitudinal axis of the base 2 is perpendicular or nearly perpendicular to the longitudinal axis of the main body 3, as shown in Figure 3.
[0040] Referring to Figures 5 to 7, the lateral rotation positioning mechanism 4 includes an engagement pin 41, an engagement recess 42, and an elastic recovery element 43. The engagement pin 41 is retractably mounted within the cavity 31 of the main body 3. In this embodiment, the engagement pin 41 is provided symmetrically on both sides of the cavity 31 of the main body 3 in the front-rear direction. The engagement recess 42 is provided on the bottom surface of the base 2 and is located on at least one side of the base 2 in the lateral direction (e.g., approximately left-right direction). In this embodiment, the engagement recess 42 is provided symmetrically on both the left and right sides of the base 2, that is, positioning on both sides is achieved. Therefore, when the child seat is installed on the left or right side of the rear seat of a vehicle (e.g., an automobile), it is convenient for children to get in and out, and usability is greatly improved. When the base 2 is rotated laterally relative to the main body 3, the engagement pin 41 is inserted into the engagement recess 42, restricting the rotation of the base 2. The elastic recovery element 43 is provided between the main body 3 and the engagement pin 41 and pushes the engagement pin 41 into the engagement recess 42. The elastic recovery element 43 is designed to allow the engagement pin 41 to be automatically inserted into the engagement recess 42, thereby automatically locking when the base 2 rotates laterally (i.e., in a sideways position), effectively improving ease of use.
[0041] As shown in Figure 6, the bottom surface of the base 2 is provided with an annular guide groove 21 coaxial with the base 2, and an engagement recess 42 is provided within the annular guide groove 21. The annular guide groove 21 can slidably contact the engagement pin 41 to guide the rotation of the base 2, and can accurately guide the engagement pin 41 to slide into the engagement recess 42, thereby improving the smoothness of rotation and the lateral positioning accuracy by the pin.
[0042] As shown in Figure 8, a locking hole 23 is provided on the bottom surface of the base 2. In this embodiment, there is one locking hole 23. The locking hole 23 is provided on the front-rear side of the base 2. When the child carrier 100 is used in the forward direction, the locking hole 23 in this embodiment is located on the rear side. When the base 2 is rotated forward relative to the main body 3, the engagement pin 41 located on the rear side of the main body 3 is inserted into the locking hole 23, restricting the rotation of the base 2. When the base 2 is rotated backward relative to the main body 3 (i.e., when the child carrier 100 is used in the rear direction), the engagement pin 41 located on the front side of the main body 3 is inserted into the locking hole 23, restricting the rotation of the base 2. In this way, by positioning the locking hole 23 on the rear or front side of the base 2, when the base 2 is positioned in the forward or rear direction, the engagement pin 41 can lock the base 2 in a forward or rearward position, thereby ensuring safety during use.
[0043] Referring to Figures 7 and 8, the base 2 is provided with a release mechanism 5 for disengaging the engagement pin 41 from the lock hole 23. By providing the release mechanism 5, the lock on the base 2 can be quickly released, improving ease of operation.
[0044] As shown again in Figure 8, the unlocking mechanism 5 includes a slider 51, a drive element 52, an elastic element 53, an operating element 54, and a recovery element 55. The slider 51 is slidably mounted on the base 2 to push the engagement pin 41 out of the lock hole 23. The middle portion of the drive element 52 is rotatably connected to the base 2, and one end of the drive element 52 is connected to the slider 51, so that when the other end of the drive element 52 is driven, it moves the slider 51. The elastic element 53 is provided between the base 2 and the slider 51 and recovers the slider 51. By providing the elastic element 53, the slider 51 can be automatically separated from the engagement pin 41, so that the engagement pin 41 can be automatically locked, accidental pushing of the engagement pin 41 can be avoided, and the safety of operation can be improved. The operating element 54 is slidably mounted on the side of the base 2 and is connected to the other end of the drive element 52. The operating element 54 is provided on the outside of the base 2 to facilitate operation by the user and improve convenience of use. The recovery element 55 is provided between the base 2 and the operating element 54 in order to recover the operating element 54. The placement of the recovery element 55 allows the operating element 54 to recover automatically, ensuring that the operation is always effective.
[0045] In relation to the above and Figures 1 to 3, the operating principle of the Child Carrier 100 of this disclosure will be described in detail below.
[0046] First, when the child carrier 100 is used in the rearward direction, the lock hole 23 of the base 2 is located on the front side and corresponds to the engagement pin 41, which is also located on the front side. The elastic element 53 pushes the slider 51 away from the lock hole 23 by its elastic force, and the engagement pin 41, receiving the elastic force of the elastic recovery element 43, is inserted into the lock hole 23, thereby locking the base 2 and restricting its rotation. At this time, the carrier body 1 on the base 2 is facing the right rear side of the body 3, that is, the child carrier 100 is in a state where it is used in the rearward direction.
[0047] When the child carrier 100 is to be used in the forward direction, the operating element 54 is manually pulled and slid upward, causing one end of the drive element 52 to swing upward while the other end of the drive element 52 swings downward. The other end of the drive element 52 presses against the slider 51, causing the slider 51 to move downward and compress the elastic element 53. As the slider 51 moves downward and approaches the lock hole 23, the slider 51 pushes against the engagement pin 41, thereby disengaging the engagement pin 41 from the lock hole 23. At this time, the lock on the base 2 is released, the base 2 rotates 180 degrees, and the carrier body 1 on the base 2 faces the rear of the body 3. Simultaneously, the lock hole 23 rotates 180 degrees towards the engagement pin 41 located on the front side, and after the slider 51 is returned, the engagement pin 41 is inserted into the lock hole 23, thereby positioning the base 2. At this time, the child carrier 100 is in the state for use in the forward direction.
[0048] When a child needs to get out of the car, the child carrier 100 needs to be used laterally. To do this, the operating element 54 is manually pulled, and the engaging pin 41 is pushed via the drive element 52 and slider 51, causing the engaging pin 41 to disengage from the lock hole 23. At this time, the lock on the base 2 is released, the base 2 rotates 90 degrees, and the carrier body 1 faces laterally to the body 3. Simultaneously, the engaging recesses 42 correspond to the engaging pins 41 one by one, and the engaging pins 41 are inserted into the engaging recesses 42 to temporarily position the base 2. At this time, the carrier body 1 is locked laterally. When it is necessary to adjust this state again, the base 2 is simply rotated directly, and the engaging pin 41 is forcibly slid out of the engaging recesses 42 by the action of the guide slope 421. At this time, the base 2 is unlocked again and can be adjusted to other states.
[0049] Compared to conventional technology, the engaging pin 41 is provided on the main body 3, and the engaging recess 42 is provided on the bottom surface of the base 2, located on at least one side of the base 2 in the lateral direction. This allows the engaging pin 41 to be inserted into the engaging recess 42 when the base 2 rotates laterally relative to the main body 3, thereby achieving the objective of restricting the rotation of the base 2. In other words, the base 2 can be stably maintained in a lateral position, making it convenient to put children in and take them out of the carrier body 1, improving usability and satisfaction, and ensuring safety by preventing the carrier body 1 from rotating and causing the child to fall during use. Furthermore, the lock on the base 2 can only be released by disengaging the engaging pin 41 from the engaging recess 42. That is, the engaging pin 41 can be disengaged from the engaging recess 42 by directly rotating the carrier body 1, resulting in ease of use and a good user experience.
[0050] Figures 9 to 13 show the structure of a child carrier in another embodiment of the present disclosure.
[0051] The structure of the child carrier in this embodiment is basically the same as in the above embodiment, except that the lateral rotation positioning mechanism 4 further includes a positioning block 44 provided on the bottom surface of the base 2, and an engagement recess 42 connected to an annular guide groove 21 is provided in the middle of the positioning block 44. The base 2 is made of plastic material and has poor wear resistance, so the engagement recess 42 directly formed on the base 2 is easily damaged by wear due to prolonged impact of the engagement pin 41. Therefore, by providing the positioning block 44, the rate and degree of wear of the engagement recess 42 are reduced, and the lifespan is extended. Moreover, the positioning block 44 is a wear-resistant positioning block made of a wear-resistant material, and specifically, it is a positioning block made of POM (polyoxyethylene resin) material, as well as a positioning block made of PA (polyamide), PEI (polyethyleneimine), etc. Furthermore, even if wear occurs, it can be replaced quickly and easily. Mounting portions 441 are provided at both ends of the positioning block 44, and mounting grooves 22 are provided on the bottom surface of the base 2. The mounting portions 441 are embedded in the mounting grooves 22 and connected to the bottom surface of the base 2. The mounting grooves 22 are provided on both sides of the annular guide groove 21. The combination of the mounting grooves 22 and the mounting portions 441 allows the positioning block 44 to be assembled to the base 2 accurately and quickly, improving the convenience of assembly and maintenance. The connection between the mounting portions 441 and the base 2 may be by screw connection, bolt connection, snap connection, adhesive connection, or welding connection. In this embodiment, the mounting portion 441 is provided with a mounting hole 441a, and after the mounting portion 441 is embedded in the mounting groove 22, the mounting portion 441 is connected to the bottom surface of the base 2 in a screw manner through the mounting hole 441a. In addition, guide slopes 421 are provided on both sides of the engagement recess 42 to guide the entry or exit of the engagement pin 41. Furthermore, by providing the guide slope 421, the guide slope 421 can guide the engagement pin 41, so when the base 2 is rotated, the guide slope 421 can be used to forcibly disengage the engagement pin 41 from the engagement recess 42, thereby achieving the objective of quick unlocking and improving the convenience of operation.The child carrier of this embodiment offers the same advantageous effects as the first embodiment, and therefore, a detailed explanation is omitted here.
[0052] The structure of the carrier body 1 of the child carrier 100 as disclosed herein is well known to those skilled in the art and will not be described in detail herein.
[0053] The descriptions disclosed above are merely preferred examples of the disclosure and should, of course, not be used to limit the scope of the disclosure. Accordingly, equivalent modifications made in accordance with the scope of the disclosure remain within the scope covered by the disclosure.
