Description

Technical Field

[0001] This utility model relates to the field of children's products technology, and in particular to a child safety seat base assembly and a child safety seat device. Background Technology

[0002] Child safety seats are widely used because they provide safety for children while traveling in vehicles. In the event of a frontal collision, a child in the vehicle is thrown forward due to inertia. The safety devices on a child safety seat can limit this forward movement. Without the protection of a child safety seat, a child could suffer injury. Currently, child safety seats typically have a seat body that can rotate relative to the base to adjust its orientation, and are secured to the base by a locking mechanism. However, the unlocking mechanism of existing locking mechanisms may have its unlocking component located at the rear of the base after the seat body rotates, making it difficult for the user to operate and unlock the seat. Utility Model Content

[0003] The main purpose of this utility model is to propose a child safety seat base assembly and a child safety seat device, which aims to solve the problem of inconvenient unlocking of existing child safety seats.

[0004] To achieve the above objectives, the present invention provides a child safety seat base assembly comprising:

[0007] A locking structure includes a locking part movably disposed on the support and a mating part disposed on the base. The locking part is movable in a locked position and an unlocked position. In the locked position, the locking part engages with the mating part to prevent the support from detaching from the base. In the unlocked position, the locking part disengages from the mating part, allowing the support to be separated from the base.

[0008] The carrier unlocking structure includes a first unlocking member and a second unlocking member movably disposed on both sides of the carrier. The first unlocking member and the second unlocking member are respectively connected to the locking part in a driving connection so that the locking part can be driven to switch from the locked position to the unlocked position during the active stroke.

[0009] In one embodiment, the base is provided with a rotating part, and the bearing seat is provided with a rotating groove that rotatably engages with the rotating part;

[0010] The mating part includes a locking groove disposed on the rotating part. The locking groove is annularly arranged so that when the base and the support rotate relative to each other, the locking part slides within the locking groove.

[0011] In one embodiment, the safety seat base assembly further includes a drive member movably mounted on the support seat, the drive member being convexly connected to the locking part, the first unlocking part and the second unlocking part being convexly connected to the drive member and driving the drive member to move, and the drive member driving the locking part to rotate during its active stroke.

[0012] In one embodiment, the locking part is rotatably mounted on the support base and is positioned to be close to or away from the rotating part during its rotational stroke;

[0013] The driving member is located on the side of the locking part that is away from the rotating part. The driving member has a first side facing the locking part and a second side facing away from the locking part. The driving member is provided with a through hole that passes through the first side and the second side. The second side is provided with a driving surface at the periphery of the through hole. The driving surface extends circumferentially along the through hole and is inclined with respect to the direction of approaching and moving away from the locking part.

[0014] A transmission member is provided between the locking part and the driving member. One end of the transmission member is hinged to the locking part at a position off the rotation center of the locking part, and the other end of the transmission member passes through the through hole and is provided with a driving part that abuts against the driving surface. The driving member is oscillating in the extension direction of the driving surface.

[0015] Both the first unlocking component and the second unlocking component are tractively connected to the driving component to drive the driving component to swing.

[0016] In one embodiment, the support seat is further provided with a seat locking member connected to the drive member, so as to drive the seat locking member to move when the drive member swings.

[0017] In one embodiment, the first unlocking member and the second unlocking member are respectively disposed on the front and rear sides of the support base.

[0018] In one embodiment, the first unlocking member and the driving member are connected by a pull-lock transmission, and the first unlocking member is rotatably mounted on the support; and / or,

[0019] The second unlocking component is connected to the driving component via a connecting rod, and the second unlocking component is slidably disposed on the support seat.

[0020] In one embodiment, locking parts and mating parts are provided with locking groups in one-to-one correspondence, and two locking groups are provided, with the two locking parts being arranged laterally at intervals on the support.

[0021] In one embodiment, both the first unlocking member and the second unlocking member are tractively connected to the two locking parts, so as to drive both locking parts to move to the unlocked position.

[0022] In one embodiment, the child safety seat base assembly further includes two drive members respectively disposed corresponding to the two locking parts;

[0023] The first unlocking component is connected to one of the two driving components via a zipper, and the second unlocking component is connected to both driving components via two connecting rods.

[0024] In addition, this utility model also provides a child safety seat device, including a safety seat base assembly and a safety seat rotatably disposed on the base of the safety seat base assembly, wherein the safety seat base assembly includes:

[0025] Base;

[0026] The support base is rotatably connected to the base.

[0027] A locking structure includes a locking part movably disposed on the support and a mating part disposed on the base. The locking part is movable in a locked position and an unlocked position. In the locked position, the locking part engages with the mating part to prevent the support from detaching from the base. In the unlocked position, the locking part disengages from the mating part, allowing the support to be separated from the base.

[0028] The carrier unlocking structure includes a first unlocking member and a second unlocking member movably disposed on both sides of the carrier. The first unlocking member and the second unlocking member are respectively connected to the locking part in a driving connection so that the locking part can be driven to switch from the locked position to the unlocked position during the active stroke.

[0029] The technical solution of this utility model, by setting the base for installing the carrier, allows the child safety seat to be installed on the vehicle seat. The carrier is rotatably connected to the base, allowing the child safety seat to rotate relative to the base to adjust its orientation. A locking part, which engages with the mating part, prevents the carrier from detaching from the base, thus securing the child safety seat on the base. Simultaneously, by setting a first unlocking member and a second unlocking member, the locking part is moved to release the restriction on the carrier, allowing it to rotate relative to the base to adjust the child safety seat's orientation. Furthermore, the first and second unlocking members are positioned at opposite ends along the longitudinal direction of the carrier, ensuring that either the first or second unlocking member is on one side of the base, regardless of whether the child safety seat is facing forward or backward, facilitating user unlocking of the locking part. This solves the problem of inconvenient unlocking of existing child safety seats. Attached Figure Description

[0043] 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 scope of protection of the present utility model.

[0044] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0045] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0046] Child safety seats are widely used because they provide safety for children while traveling in a car. In the event of a frontal collision, a child in the vehicle will be thrown forward due to inertia. The safety devices on a child safety seat can limit this forward movement. Without the protection of a child safety seat, a child could be injured.

[0047] Currently, car seats typically rotate relative to their base and are secured to the base via a locking mechanism. This allows the car seat to be installed facing forward (with the child facing the direction of travel) or rear-facing (with the child facing away from the direction of travel). However, the unlocking mechanism in existing locking mechanisms may, after rotating with the seat, be positioned at the rear of the base, making it difficult for the user to unlock the seat.

[0048] Analysis of the causes of the above problems reveals that the unlocking component in the existing locking mechanism rotates with the child safety seat. During the rotation of the child safety seat, the unlocking component, which is located at the front of the base, may rotate to the rear of the base. The user needs to reach to the rear of the base to operate the unlocking component, which is inconvenient for the user. To solve the problem of user inconvenience in unlocking, the structure of the locking mechanism can be improved so that the unlocking component of the locking mechanism can be easily unlocked by the user.

[0049] Based on this, this utility model proposes a child safety seat base assembly for use in child safety seat devices, aiming to solve the problem of inconvenient unlocking of existing child safety seats. Among other things, Figures 1 to 6 A schematic diagram of the structure of the safety seat base assembly provided by this utility model; Figure 7 A schematic diagram of the child safety seat device provided by this utility model.

[0050] Please see Figure 1 , Figure 2 and Figure 6 In one embodiment of this utility model, the safety seat base assembly 100 includes a base 1, a support 2, a locking structure 3, and a support unlocking structure 5. The support 2 is rotatably connected to the base 1. The support unlocking structure 5 includes a locking part 31 movably disposed on the support 2 and a mating part 32 disposed on the base 1. The locking part 31 is movable in a locked position and an unlocked position. In the locked position, the locking part 31 engages with the mating part 32 to restrict the support 2 from detaching from the base 1. In the unlocked position, the locking part 31 disengages from the mating part 32 to allow the support 2 to be separated from the base 1. The support unlocking structure 5 includes a first unlocking member 51 and a second unlocking member movably disposed on both sides of the support 2. The first unlocking member 51 and the second unlocking member 52 are respectively drivenly connected to the locking part 31 so that the locking part 31 can be driven to switch from the locked position to the unlocked position during its active stroke.

[0051] It should be noted that the base 1 refers to a structure that allows the support seat 2 to rotate. This structure needs to have a certain strength and hardness, and its material can be various, such as metals like iron and aluminum, inorganic non-metallic materials like ceramics, or polymer materials like plastics. This utility model does not limit this. Furthermore, the base 1 can have various shapes, such as circular, rectangular, or elliptical, etc. This utility model does not limit this.

[0052] It is understood that the support seat 2 is mainly used for mounting the safety seat 200, and its material can be various, such as metals like iron and aluminum, inorganic non-metallic materials like ceramics, or polymer materials like plastics. This invention does not limit this. Furthermore, the support seat 2 can have various shapes; the base 1 can be rhomboid, rectangular, elliptical, etc., and this invention does not limit this. Furthermore, the support seat 2 and the base 1 can be rotatably connected in various ways. One of the support seat 2 and the base 1 can be a pivot, and the other can be a sleeve that can be fitted onto the pivot, allowing the support seat 2 and the base 1 to rotate relative to each other. In addition, the two sides of the support seat 2 can be either left-right or front-back, and this invention does not limit this.

[0053] The technical solution of this utility model, by setting the base 1 to install the support seat 2, allows the safety seat 200 to be installed on the vehicle seat. The support seat 2 is rotatably connected to the base 1, allowing the safety seat 200 to rotate relative to the base 1 to adjust its orientation. The locking part 31, which engages with the mating part 32, prevents the support seat 2 from detaching from the base 1, thus securing the safety seat 200 on the base 1. Simultaneously, the first unlocking member 5... The first unlocking member 51 and the second unlocking member 52 are arranged on both sides of the base 2 to drive the locking part 31 to move, thereby releasing the restriction on the support seat 2 and allowing the support seat 2 to separate from the base 1. At the same time, the first unlocking member 51 and the second unlocking member 52 are arranged on both sides of the support seat 2 so that whether the safety seat 200 is arranged facing forward or backward on the base 1, one of the first unlocking member 51 and the second unlocking member 52 can be located on one side of the base 1, making it convenient for the user to unlock the locking part 31, thereby solving the problem of inconvenient unlocking of existing child safety seats 200.

[0054] Further, please refer to Figures 3 to 5 The base 1 is provided with a rotating part 11, and the support seat 2 is provided with a rotating groove that rotatably engages with the rotating part 11. The engaging part 32 includes a locking groove corresponding to the rotating part 11. The locking groove is annularly arranged so that when the base 1 and the support seat 2 rotate relative to each other, the locking part 31 can slide within the locking groove. Thus, by using the annularly arranged locking groove to engage with the locking part 31, the support seat 2 can be confined to the base 1 without affecting the rotation of the support seat 2, making it convenient for the user to adjust the orientation of the safety seat 200.

[0055] The locking part 31 is movably disposed in the direction close to the rotating part 11, so that the locking part 31 can switch between the locked position and the unlocked position, so that the locking part 31 can both extend into the locking groove to restrict the vertical movement of the support 2 and the base 1 to confine the support 2 to the base 1, and disengage from the locking groove to release the restriction on the support 2, so that the support 2 can be disengaged from the base 1 for disassembly of the safety seat.

[0056] In one embodiment of this utility model, please refer to Figure 4 and Figure 5The locking part 31 is rotatably mounted on the support seat 2 and can be positioned close to or away from the rotating part 11 during its rotational stroke. The safety seat base assembly 100 also includes a driving member 6 movably mounted on the support seat 2. The driving member 6 is convexly connected to the locking part 31. The first unlocking member 51 and the second unlocking member 52 are both convexly connected to the driving member 6 and drive the driving member 6 to move. The driving member 6 drives the locking part 31 to rotate during its active stroke.

[0057] It should be noted that the locking part 31 can move in various ways in the direction close to the rotating part 11. The locking part 31 can be linearly mounted on the support 2 or rotatably mounted on the support 2. This utility model does not limit this, but since linear movement requires a large space, and the installation space inside the support 2 is limited, the locking part 31 is rotatably mounted in order to reduce the movement stroke of the locking part 31, thereby facilitating its installation inside the support 2.

[0058] In this embodiment, the first unlocking member 51 and the second unlocking member 52 are both tractively connected to the driving member 6, so that the first unlocking member 51 and the second unlocking member 52 can both drive the driving member 6 to move. The driving member 6 is tractively connected to the locking part 31, so that the driving member 6 can drive the locking part 31 to swing away from the rotating part 11, so that the locking part 31 can move from the locked position to the unlocked position, releasing the restriction on the connecting shaft, and allowing the support seat 2 to detach from the base 1.

[0059] Further, please refer to Figures 1 to 4 The driving member 6 is located on the side of the locking part 31 opposite to the rotating part 11. The driving member 6 has a first side 61 facing the locking part 31 and a second side 62 opposite to the locking part 31. The driving member 6 is provided with a through hole 63 that passes through the first side 61 and the second side 62. The second side 62 is provided with a driving surface 621 at the periphery of the through hole 63. The driving surface 621 extends circumferentially along the through hole 63 and is inclined with respect to the direction of approaching and moving away from the locking part 31. A transmission member 7 is provided between the locking part 31 and the driving member 6. One end of the transmission member 7 is hinged to the locking part 31 at a position off its rotation center. The other end of the transmission member 7 passes through the through hole 63 and is provided with a driving part 71 that abuts against the driving surface 621. The driving member 6 is swingable in the extension direction of the driving surface 621. The first unlocking member 51 and the second unlocking member 52 are both drivenly connected to the driving member 6 to drive the driving member 6 to swing.

[0060] It should be noted that the driving member 6 can move in various ways. It can be rotatably mounted on the support 2, or it can be linearly mounted on the support 2, etc. This invention does not limit this. Similarly, the driving surface 621 can be positioned in various ways. It can be located on the first side 61 or the second side 62, and this invention does not limit this. If the driving surface 621 is located on the first side 61, the end of the transmission member 7 facing away from the locking part 31 abuts against the driving surface 621. This converts the rotation of the driving member 6 into linear movement of the transmission member 7, enabling the transmission member 7 to drive the locking part 31 to swing.

[0061] It should also be noted that the driving part 71 and the transmission component 7 can be formed in various ways. The driving part 71 and the transmission component 7 can be integrally formed or separately formed, and this utility model does not limit them in this regard. Furthermore, the driving part 71 can have various shapes, such as cylindrical or prismatic, and this utility model does not limit it in this regard.

[0062] In this embodiment, by providing the through hole 63 for the other end of the transmission member 7 to pass through, the driving part 71 can abut against the driving surface 621 on the driving member 6. By providing the driving surface 621, when the driving member 6 swings, the driving part 71 can move towards or away from the locking part 31, so as to convert the rotation of the driving member 6 into the linear movement of the transmission member 7. By providing the transmission member 7, the locking part 31 is driven to swing, so that the locking part 13 can move away from the rotating part 11, so that the locking part 31 releases the restriction on the bearing seat 2.

[0063] In one embodiment of this utility model, please refer to Figure 2 and Figure 4 The safety seat base assembly 100 also includes a reset member 4 disposed between the locking part 31 and the support seat 2, for resetting the locking part 31 to the locked position. Thus, by providing the reset member 4, the locking part 31 is automatically driven to move toward the locked position, thereby reducing the frequency of user operation.

[0064] Furthermore, the reset component 4 includes a reset spring 41, one end of which is connected to the support seat 2, and the other end is connected to a position off-center of the locking part 31, so as to rotate the locking part 31 back to the locked position. Thus, by providing the reset spring 41, the locking part 31 is driven to move closer to the rotating part 11 to engage with the mating part 32, preventing the support seat 2 from disengaging from the base 1. Of course, in other embodiments, the reset component 4 can be rubber, or a linear drive structure, etc., as long as it can reset the locking part 31 to the locked position; this utility model does not limit this.

[0065] In one embodiment of this utility model, please refer to Figure 1 The support 2 is also provided with a seat locking member connected to the drive member 6, so that the seat locking member can be moved when the drive member 6 swings. Thus, the drive member 6 is swing-configured so that the drive member 6 can both drive the locking part 31 to unlock and drive the seat locking member to unlock, so that both ends of the drive member 6 can be used to transmit driving force, so as to unlock the two locking mechanisms on the safety seat 200 at the same time.

[0066] In one embodiment of this utility model, please refer to Figure 1 and Figure 2 The support 2 is provided with a mounting groove 22 for mounting the transmission member 7 and the locking part 31. Thus, by providing the mounting groove 22, it is convenient to install the transmission member 7 and the locking part 31, and it can also guide the transmission member 7 to move in a straight line to drive the locking part 31 to swing, thereby helping to improve the stability of the movement of the transmission member 7 and the locking part 31.

[0067] In one embodiment of this utility model, the first unlocking member 51 and the second unlocking member 52 may be disposed on both sides of the support base 2 in the left-right direction, or on both sides of the support base 2 in the front-back direction. This utility model does not limit this. For details, please refer to Figure 1 , Figure 6 and Figure 7The first unlocking member 51 and the second unlocking member 52 are respectively disposed on the front and rear sides of the support seat 2. When the safety seat 200 is disposed facing forward (with the child facing the direction of travel) on the base 1, one of the first unlocking member 51 and the second unlocking member 52 is located on the front side of the base 1, and the user can directly operate the unlocking member to unlock the locking part. When the safety seat 200 is disposed in reverse (with the child facing away from the direction of travel) on the base 1, the other of the first unlocking member 51 and the second unlocking member 52 is located on the front side of the base 1, and the user can directly operate the unlocking member to unlock the locking part. In this way, by arranging the first unlocking member 51 and the second unlocking member 52 in the front and rear directions, whether the safety seat 200 is disposed facing forward or in reverse, one of the first unlocking member 51 and the second unlocking member 52 can be located on the front side of the base 1, thereby facilitating the user to operate the unlocking.

[0068] In one embodiment of this utility model, please refer to Figure 6 The first unlocking member 51 is connected to the driving member 6 via a zipper 81, and the first unlocking member 51 is rotatably mounted on the support base 2. When it is necessary to unlock the locking part 31, the user operates the first unlocking member 51 to rotate, thereby driving the zipper 81 to move, so that the zipper 81 can pull the driving member 6 to move, so that the driving member 6 can drive the locking part 31 to unlock. Thus, by setting the zipper 81 to connect the first unlocking member 51 and the driving member 6, the first unlocking member 51 can operate the driving member 6 to move, thereby enabling the first unlocking member 51 to unlock the locking part 31.

[0069] In another embodiment of this utility model, please refer to Figure 1 and Figure 6 The second unlocking member 52 is connected to the driving member 6 via a connecting rod 82, and the second unlocking member 52 is slidably disposed on the support seat 2. When it is necessary to unlock the locking part 31, the user operates the second unlocking member 52 to slide, thereby driving the driving member 6 to move synchronously, so that the driving member 6 can drive the locking part 31 to unlock. In this way, by setting the connecting rod 82 to connect the second unlocking member 52 and the driving member 6, the second unlocking member 52 can operate the driving member 6 to move, thereby enabling the second unlocking member 52 to unlock the locking part 31.

[0070] It should be noted that the two related technical features mentioned above, namely, "the first unlocking member 51 and the driving member 6 are connected by a pull lock 81" and "the second unlocking member 52 and the driving member 6 are connected by a connecting rod 82", can be set either one or both, and this utility model does not limit them.

[0071] In one embodiment of this utility model, please refer to Figure 1 and Figure 6 The locking part 31 and the cooperating part 32 are respectively provided with locking groups. Two locking groups are provided. The two locking parts 31 are arranged laterally on the bearing seat 2. In this way, by providing two locking parts 31, the two ends of the rotating part 11 in the lateral direction are simultaneously positioned on the base 1, thereby helping to improve the locking effect of the locking mechanism.

[0072] It should be noted that the "horizontal" refers to a horizontal direction, which can be left-right or front-back, etc. This utility model does not limit this. The horizontal direction is orthogonal to the vertical direction. For example, the horizontal direction is left-right and the vertical direction is front-back.

[0073] Further, please refer to Figure 1 and Figure 6 The first unlocking member 51 and the second unlocking member 52 are both tractively connected to the two locking parts 31, driving both locking parts 31 to the unlocked position so that both the first unlocking member 51 and the second unlocking member 52 can unlock both locking parts 31 simultaneously. Of course, in other embodiments, the two locking parts 31 include a first locking part and a second locking part, with the first unlocking member 51 tractively connected to the first locking part and the second unlocking member 52 tractively connected to the second unlocking member 52. This allows the first unlocking member 51 and the second unlocking member 52 to unlock the two locking parts 31 respectively, but this arrangement makes unlocking more cumbersome.

[0074] Furthermore, the safety seat base assembly 100 also includes two drive members 6 respectively corresponding to the two locking parts 31. The first unlocking member 51 is connected to one of the two drive members 6 via a pull lock 81, and the second unlocking member 52 is connected to the two drive members 6 via two connecting rods 82.

[0075] It should be noted that there are multiple ways in which the first unlocking member 51 and the second unlocking member 52 can simultaneously unlock the two locking parts 31. For example, the first unlocking member 51 and the second unlocking member 52 can be connected to the two driving members 6 by the two connecting rods 82, or they can be connected to the two driving members 6 by the two zippers 81. This utility model does not limit this. However, if the first unlocking member 51 and the second unlocking member 52 are connected to the two driving members 6 by the two zippers 81, the cost is high. If the first unlocking member 51 and the second unlocking member 52 are connected to the two driving members 6 by the two connecting rods 82, the space of the support seat 2 will be limited, and it is easy to interfere with other structures.

[0076] In this embodiment, by providing two connecting rods 82, the second unlocking member 52 can be connected to the two driving members 6, so that the second unlocking member 52 can unlock the two locking parts 31 simultaneously. At the same time, the torque of one driving member 6 can be transmitted to the other driving member 6, so that the two driving members 6 can rotate synchronously. Meanwhile, by providing a zipper 81, the first unlocking member 51 can be connected to one of the driving members 6, so that the first unlocking member 51 can unlock the two locking parts 31 simultaneously. This reduces costs and the probability of interference with other structures.
