Description

A laterally sliding base and child carrier Technical Field

[0001] This application relates to child vehicles, and more particularly to a laterally sliding base and a child vehicle. Background Technology

[0002] With increasing awareness of traffic safety, people are paying more and more attention to protecting infants and young children when traveling by car. Furthermore, the frequency with which people take infants and young children out in cars is also increasing. As a result, child safety seats have become widely popular and used. Conventional child safety seats connect to the rear seat via a base, and the child safety seat is then clipped and locked onto the base for the infant's safety. However, to facilitate retrieving the infant or separating the child safety seat from the base when getting out of the car, it is inconvenient to directly retrieve the infant or detach the child safety seat, as both the child safety seat and base are installed near or close to the middle of the rear seat.

[0003] To address this issue, child safety seats with side-sliding capabilities have emerged on the market. After opening the rear door, the user first unlocks the rotating mechanism to rotate the child safety seat relative to the base towards the door, then unlocks the side-sliding mechanism to move the child safety seat relative to the base towards the corresponding door, thus providing convenience for the user. Specifically, Chinese patents CN219856889U and CN221418025U disclose child car seats with side-sliding capabilities. In these two patents, rotation and sliding are achieved sequentially and independently by different functional components, with the sliding component located on top of the rotating component. This design results in a thick, heavy base that is inconvenient to carry. Furthermore, it requires a second unlocking operation to achieve the final lateral movement, causing inconvenience for the user.

[0004] For example, Chinese patent application CN117818435A discloses a child safety seat with electric rotation and sliding functions and its usage method. It controls the rotation and sliding of the child safety seat relative to the base in an electric manner. Compared with the solutions of the two aforementioned Chinese patents CN219856889U and CN 221418025 U, this design solves the problem of the user needing to perform secondary operations, which is inconvenient. However, the shortcomings of the solution disclosed in this patent application are also very obvious. Its structure and transmission are complicated in the field of child vehicles, and the base designed in this way also has the disadvantages of being thick and heavy.

[0005] In view of the above-mentioned technical problems, this application is hereby proposed. Application content

[0006] The technical problem this application aims to solve is to provide a laterally sliding base and child carrier, including a base body and a turntable. By setting a rotation offset mechanism between the turntable and the base body, the turntable can switch from a first usage state to a second usage state in a single operation. When the child carrier body is connected to the base body via the turntable, if the user needs to pick up or remove the infant or child on the child carrier body, or detach the child carrier body from the rear seat of the vehicle, the user can switch the turntable to the second usage state in one operation, allowing the child carrier body to slide closer to or extend out of the corresponding door of the rear seat of the vehicle. This structural design makes it convenient for users to pick up or remove the infant or child, avoiding the need to put part of their body into the rear seat. It has the characteristics of convenient operation. Moreover, with this structural design, the overall structure of the base is simple and reasonable, with a small thickness and light weight, making it convenient for people to carry when going out.

[0007] To solve the above-mentioned technical problems, this application provides a laterally sliding base, including a base body 1 and a turntable 2. The base body 1 is used to install and connect to the rear seat of a vehicle. The turntable 2 is used to support a child carrier body 3 and is detachably connected to the child carrier body 3. A rotation offset mechanism 4 is provided between the turntable 2 and the base body 1. The turntable 2 has a first use state and a second use state. In the first use state, the front-back direction of the child carrier body 3 connected to the turntable 2 is parallel to the travel direction of the vehicle connected to the base body 1. In the second use state, the front-back direction of the child carrier body 3 connected to the turntable 2 is perpendicular to the travel direction of the vehicle connected to the base body 1. The rotation offset mechanism 4 is configured such that the movement of the turntable 2 relative to the base body 1 includes at least a rotational movement to switch from the first use state to the second use state. In the second use state, the child carrier body 3 connected to the turntable 2 is close to or extends out of the corresponding rear door side of the vehicle.

[0008] As described above, in a laterally sliding base, the rotation offset mechanism 4 is located between the turntable 2 and the base body 1, so that the turntable 2 and the base body 1 form a two-layer connection structure, and the turntable 2 is constrained to the base body 1 and can move in a plane relative to the base body 1.

[0009] As described above, in a laterally sliding base, the rotation offset mechanism 4 is configured such that when the turntable 2 switches from a first use state to a second use state, the movement of the child carrier body 3 relative to the base body 1 is a composite motion of rotational motion and linear motion superimposed on each other.

[0010] As described above, a laterally sliding base includes a rotation offset mechanism 4 comprising a first guide portion 41 and a rotation guide member 42 disposed on a turntable 2, and a second guide portion 43 and a limiting portion 44 disposed on the base body 1.

[0012] As described above, a laterally sliding base also includes a rotation control mechanism 5 located between the turntable 2 and the base body 1. The rotation control mechanism 5 is configured to lock the turntable 2 relative to the base body 1 in a first use state. The rotation control mechanism 5 includes a rotation locking member 51 that can be elastically extended and retracted, a rotation locking hole 52 that is inserted and engaged with the rotation locking member 51, and a rotation unlocking component 53 disposed on the base body 1 for driving the rotation locking member 51 to disengage from the rotation locking hole 52.

[0013] As described above, in a laterally sliding base, the rotation locking hole 52 is disposed at the bottom of the second guide portion 43, and the rotation locking member 51 is disposed on the rotation guide member 42.

[0014] As described above, in a laterally sliding base, the rotation unlocking assembly 53 includes a rotation handle 531, a rotation unlocking drive 532, and a rotation unlocking elastic member 533. The middle part of the rotation handle 531 is rotatably connected to the base body 1, and one end protrudes from the base body 1 for unlocking operation. The rotation unlocking drive 532 is disposed at the other end of the rotation handle 531, and the rotation unlocking elastic member 533 is disposed between the rotation handle 531 and the base body 1 so that the rotation unlocking drive 532 automatically resets after the unlocking action is released.

[0015] As described above, in a laterally sliding base, two rotating handles 531 are symmetrically arranged at the front of the base body 1, and the opposing ends of the two rotating handles 531 are connected to the rotating unlocking drive 532.

[0016] As described above, in a laterally sliding base, the rotation offset mechanism 4 is configured such that when the turntable 2 switches from a first use state to a second use state, the movement of the child carrier body 3 relative to the base body 1 is a single rotational motion. The rotation offset mechanism 4 includes a rotation axis 45 offset from the geometric center O of the turntable 2 for pivoting the turntable 2 and the base body 1. The rotation axis 45 is offset from the geometric center O of the turntable 2 along the front or rear side, or the rotation axis 45 is offset from the geometric center O of the turntable 2 along the left or right side.

[0017] This application also provides a child vehicle, including a child vehicle body 3 and a laterally sliding base as described above.

[0018] As described above, a child vehicle body 3 is provided with a support assembly 31 movably mounted on the child vehicle body 3. The child vehicle body 3 is detachably connected to the turntable 2 via the support assembly 31. The tilt angle of the child vehicle body 3 relative to the turntable 2 can be adjusted under the guidance of the support assembly. The child vehicle body 3 is also provided with a locking mechanism 32 for limiting the relative movement of the support assembly and the child vehicle body 3, and an operating part 33 for unlocking the locking mechanism.

[0019] As described above, in a child vehicle, the support assembly 31 includes a side connecting plate 311, a locking rod 312 for connecting to a turntable 2 is provided between the two side connecting plates 311, and a guide slide rod 313 is provided on the outer side of the two side connecting plates 311. The bottom and back sides of the child vehicle body 3 are provided with receiving grooves 30 for accommodating the support assembly 31. The sidewall of the receiving groove 30 is provided with an adjusting groove 314 for slidingly engaging with the guide slide rod 313. The locking mechanism 32 includes an adjusting lock hole 321 provided at the front end of the side connecting plate 311 and an adjusting lock pin 322 that is elastically telescopically provided on the child vehicle body 3 for locking with the adjusting lock hole 321. The operating part 33 includes an operating button 331 that is movably connected to the child vehicle body 3. The operating button 331 is provided with an adjusting drive part 332 for driving the adjusting lock pin 322 out of the adjusting lock hole 321.

[0020] As described above, in a child vehicle, the operation unit 33 is configured to be triggered when switching from a first use state to a second use state, thereby unlocking the locking mechanism 32, so that the child vehicle body 3 can adjust its tilt angle relative to the turntable 2 to be closer to or extend out of the corresponding rear door side of the vehicle.

[0021] Compared with the prior art, the laterally sliding base and child carrier of this application have the following advantages:

[0022] 1. A rotation offset mechanism is set between the base body and the turntable. This not only allows the user to switch from the first usage state to the second usage state in one operation after the turntable is unlocked, but also allows the child carrier body connected to the turntable to approach or extend to the corresponding rear door side of the vehicle in the second usage state. This makes it convenient for the user to pick up the infant or to detach the child carrier body from the base body. It is easy to operate and use, and does not affect the overall thickness and weight of the base. After increasing its functions, its thickness and weight are smaller than existing similar products. It also has a simpler and more reasonable structure than similar products, and better control of costs, thereby improving the competitiveness of the product.

[0023] 2. A support assembly is movably installed on the child vehicle body. Under normal use, the user can adjust the tilt angle of the child vehicle body relative to the base body to meet their diverse usage needs. In a second usage state, the support assembly guides the child vehicle body to move closer to or extend beyond the corresponding door side of the rear seat of the vehicle, further improving the convenience and comfort of use.

[0047] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0048] As shown in Figures 1-22, this application discloses a laterally sliding base, including a base body 1 and a turntable 2. The base body 1 is used to install and connect to the rear seat of a vehicle, and the turntable 2 is used to support the child carrier body 3 and is detachably connected to the child carrier body 3. In this application, the child carrier body 3 can be an infant carrier body or a child safety seat body. A rotation offset mechanism 4 is provided between the turntable 2 and the base body 1. The rotation offset mechanism 4 is mainly a structure that connects the turntable 2 and the base body 1 itself. Therefore, the rotation offset mechanism 4 does not affect the overall thickness and size of the base. The turntable 2 has a first use state and a second use state. In the first use state, the front-back direction of the child carrier body 3 connected to the turntable 2 is parallel to the travel direction of the vehicle connected to the base body 1. In the second use state, the front-back direction of the child carrier body 3 connected to the turntable 2 is perpendicular to the travel direction of the vehicle connected to the base body 1. The rotation offset mechanism 4 is configured such that the movement of the turntable 2 relative to the base body 1 includes at least a rotational movement to switch from the first use state to the second use state. In the second use state, the child carrier body 3 connected to the turntable 2 is close to or extends out of the corresponding rear door side of the vehicle. By setting up a rotation offset mechanism, the turntable can be unlocked and switched from the first usage state to the second usage state in one operation. In the second usage state, the child carrier body connected to the turntable can be close to or extend from the corresponding rear door side of the vehicle, making it convenient for users to pick up infants or to detach the child carrier body from the base body. It has the characteristics of convenient operation and use, and does not affect the overall thickness and weight of the base. After increasing its functions, its thickness and weight are smaller than existing similar products, and its structure is simpler and more reasonable than similar products, as well as better cost control, thus improving the competitiveness of the product.

[0049] As shown in Figures 4, 13, and 17, the rotation offset mechanism 4 is located between the turntable 2 and the base body 1, forming a two-layer connection structure between the turntable 2 and the base body 1. The turntable 2 is constrained to the base body 1 and can move in a planar manner relative to the base body 1. In the first use state, the turntable is locked relative to the base body. As shown in Figures 4, 6, and 8, the base body 1 includes an upper base 11 and a lower base 12 connected to each other. The upper part of the turntable 2 protrudes from the upper base 11 to support and connect to the child carrier body 3, and the lower part of the turntable is embedded in the upper base 11 and the lower base 12. Therefore, it can be ensured that the overall thickness of the base has a small dimension.

[0050] As the first embodiment of this application, and also the preferred embodiment of this application, as shown in Figures 1-12, the rotation offset mechanism 4 is configured such that the turntable 2 switches from the first use state to the second use state, causing the child carrier body 3 to move relative to the base body 1 in a composite motion of rotational motion and linear motion. Therefore, in actual use, the turntable only needs one action to switch from the first use state to the second use state.

[0051] Specifically, as shown in Figures 6-9, the rotation offset mechanism 4 includes a first guide portion 41 and a rotation guide member 42 disposed on the turntable 2, and a second guide portion 43 and a limiting portion 44 disposed on the base body 1. The first guide portion 41 is a straight groove, the length direction of which is parallel to the front-rear direction of the child carrier body 3 in the first use state. The limiting portion 44 is a cylindrical member with an internal threaded hole fixedly connected to the lower base 12. The first guide portion 41 is slidably and rotatably connected to the limiting portion 44. The rotation guide member 42 is slidably connected to the second guide portion 43. The second guide portion 43 is an arc-shaped groove, as shown in Figure 8. The arc-shaped groove is located at the front of the lower base 12 of the base body 1, and the arc-shaped groove is symmetrically arranged about axis a. Correspondingly, the rotation guide member 42 is disposed on the bottom front side of the turntable 2. Alternatively, in this application, the second guide portion 43 can also be disposed at the rear of the lower base 12 of the base body 1, and the rotation guide member 42 is disposed on the bottom rear side of the turntable 2.

[0052] As shown in Figure 2-4, when the turntable rotates relative to the base body, the turntable can shift to the left or right accordingly. This allows the child carrier body connected to the turntable to move closer to or extend beyond the corresponding rear door side of the vehicle's rear seat, facilitating the user's retrieval of the infant or child carrier body. Furthermore, this structural design clearly demonstrates that the rotational offset mechanism between the turntable and the base body utilizes the original connection space between them. Therefore, even with the added sliding function, the thickness of the base in this application can be significantly less than that of similar existing products, resulting in a lighter overall weight. This makes it convenient for users to carry and store, facilitates packaging, and reduces production costs.

[0053] As shown in Figures 8-12, the base of this application also includes a rotation control mechanism 5 located between the turntable 2 and the base body 1. The rotation control mechanism 5 is configured to lock the turntable 2 relative to the base body 1 in the first use state. The rotation control mechanism 5 includes a rotation locking member 51 that can be elastically extended and retracted, a rotation locking hole 52 that is inserted and engaged with the rotation locking member 51, and a rotation unlocking component 53 disposed on the base body 1 for driving the rotation locking member 51 to disengage from the rotation locking hole 52.

[0054] To ensure structural simplicity, the rotating locking hole 52 is located at the bottom of the second guide portion 43, and the rotating locking element 51 is located on the rotating guide portion 42. The rotating unlocking assembly 53 includes a rotating handle 531, a rotating unlocking drive element 532, and a rotating unlocking elastic element 533. The middle part of the rotating handle 531 is rotatably connected to the base body 1, with one end protruding from the base body 1 for unlocking operations. The rotating unlocking drive element 532 is located at the other end of the rotating handle 531, and the rotating unlocking elastic element 533 is located between the rotating handle 531 and the base body 1 so that the rotating unlocking drive element 532 automatically resets after the unlocking action is released. During unlocking, applying force to the outer end of the rotating handle 531 causes the rotating unlocking drive element 532 to push the rotating locking element 51 out of the rotating locking hole 52, allowing the turntable to rotate.

[0055] As shown in Figures 2 and 3, in actual use, the base of this embodiment can be installed on either the left or right side of the rear seat of a vehicle. Therefore, for ease of operation and without the need for user identification, the two rotating handles 531 are symmetrically arranged on the front of the base body 1. The opposing ends of the two rotating handles 531 are connected to the rotating unlocking drive 532. Users can choose to install on the left or right side according to their needs and can easily unlock the base from either side.

[0056] As a second embodiment of this application, as shown in Figures 13-19, the rotation offset mechanism 4 is configured such that the movement of the child carrier body 3 relative to the base body 1 when the turntable 2 switches from a first use state to a second use state is a single rotational motion. The rotation offset mechanism 4 includes a rotation axis 45 offset from the geometric center O of the turntable 2 for pivoting the turntable 2 and the base body 1. As shown in Figures 13-16, as scheme A of the second embodiment, the rotation axis 45 is offset from the geometric center O of the turntable 2 along the front or rear side. In scheme A, the turntable can be selectively moved to the left or right, similar to the first embodiment.

[0057] As shown in Figures 17-19, in Scheme B of the second embodiment, the rotating shaft 45 is offset to the left or right relative to the geometric center O of the turntable 2. Scheme B presents limitations in use. When the rotating shaft 45 is offset to the left relative to the geometric center O of the turntable 2, the turntable can only rotate to the left relative to the base body, and the base can only be installed on the left side of the rear seat of the vehicle. When the rotating shaft 45 is offset to the right relative to the geometric center O of the turntable 2, the turntable can only rotate to the right relative to the base body, and the base can only be installed on the right side of the rear seat of the vehicle. Therefore, Scheme B requires user identification.

[0058] This application further provides a child vehicle for use with the base of this application, including a child vehicle body 3 and a base that can slide laterally as described above.

[0059] Corresponding to the base of this application, regardless of the scheme in the above embodiments, the offset distance of the corresponding rear door of the vehicle is limited. To address the limitations of the base in this application, a child carrier is provided. A movable support assembly 31 is provided on the child carrier body 3. The child carrier body 3 is detachably connected to the turntable 2 via the support assembly 31. The tilt angle of the child carrier body 3 relative to the turntable 2 can be adjusted under the guidance of the support assembly. The child carrier body 3 is also provided with a locking mechanism 32 for limiting the relative movement of the support assembly and the child carrier body 3, and an operating part 33 for unlocking the locking mechanism. Under normal use, the user can adjust the tilt angle of the child carrier body relative to the base body to meet diverse usage needs. Therefore, in a second usage state, the child carrier body can be guided closer to or extended beyond the corresponding rear door side of the vehicle through the support assembly, further improving the convenience and comfort of use.

[0060] As shown in Figure 22, the support assembly 31 includes a side connecting plate 311, a locking rod 312 for connecting to the turntable 2 is provided between the two side connecting plates 311, a guide slide rod 313 is provided on the outer side of the two side connecting plates 311, and a receiving groove 30 for accommodating the support assembly 31 is provided on the bottom and back sides of the child carrier body 3. An adjusting groove 314 for sliding cooperation with the guide slide rod 313 is provided on the side wall of the receiving groove 30. The locking mechanism 32 includes a plurality of adjusting locking holes 321, an adjusting locking pin 322 and an adjusting reset member 32 provided at the front end of the side connecting plate 311. 3. The adjusting reset member 323 elastically presses against the adjusting locking pin 322 to keep it locked in place with the adjusting lock hole 321. The adjusting locking pin 322 is formed by the extension of the locking rod 312. The operating part 33 includes an operating button 331 that can be movably connected to the child carrier body 3. The operating button 331 is provided with an adjusting drive part 332 which is a slanted groove. When adjustment or unlocking is required, the operating button 331 is activated, and the adjusting drive part 332 drives the adjusting locking pin 322 to disengage from the adjusting lock hole 321. At this time, the child carrier body 3 can slide and adjust relative to the support assembly.

[0061] To improve ease of operation, the operating unit is configured to be triggered when switching from the first usage state to the second usage state, thereby unlocking the locking mechanism 32. This allows the child carrier body 3 to adjust its tilt angle relative to the turntable 2 to be closer to or extend beyond the corresponding rear door side of the vehicle. To achieve this function, a trigger can be provided at the corresponding position on the base body 1. When the turntable drives the child carrier body 3 to switch from the first usage state to the second usage state, the trigger acts on the operating unit, causing the operating unit to release the locking mechanism relative to the support assembly, thereby allowing the user to directly adjust the tilt angle of the child carrier body 3 relative to the base body.
