Description

Technical Field

[0001] The present disclosure relates to a side impact protection system, and more specifically, to a side impact protection mechanism attached to a child carrier.

Background Art

[0002] A child seat is mounted on a vehicle seat, such as an automobile seat, for a child to sit on, and can ensure the safety of the child during riding. Therefore, child seats are becoming increasingly popular and widely used. Since side impacts frequently occur in automobile accidents, child seats equipped with side impact protection mechanisms are commercially available to prevent the death or injury of children during side impacts.

[0003] The side impact protection mechanism generally includes an operating part, a locking device, and a side impact protection block. When located in the deployment position, the side impact protection block can partially protrude from the side of the child seat. When located in the folded position, the side impact protection block can be in close contact with the side of the child seat. When the operating part is operated, the operating part drives the locking device to unlock the side impact protection block and move the side impact protection block from the deployment position to the folded position. However, the conventional side impact protection block has a complex structure and is difficult to operate. Therefore, there is a need to provide an improved side impact protection mechanism.

Summary of the Invention

[0004] Therefore, an object of the present disclosure is to provide a side impact protection mechanism with a simple structure and easy operation.

[0005] As can be seen more clearly from the detailed description, the side impact protection mechanism is located on the side of the child carrier and includes a side impact protection block, a locking component, and an operating component. The side impact protection block is rotatably connected to the side and is switchable between a folded position and an extended position relative to the side. When the side impact protection block is in the folded position, it is in close contact with the side, and when the side impact protection block is in the extended position, it protrudes at least partially from the side. The locking component is at least partially movably located within the side impact protection block and is switchable between a locked position and an unlocked position relative to the side impact protection block. When the locking component is in the locked position, the side impact protection block is prevented from rotating away from the extended position relative to the side, and when the locking component is in the unlocked position, the side impact protection block can rotate from the extended position to the folded position relative to the side. The operating component is movably positioned in the side impact protection block and is configured to drive the locking component to move toward the release position.

[0006] According to one embodiment of the present invention, when the locking component moves from the locking position toward the release position, the locking component moves along a direction away from the side.

[0007] According to one embodiment of the present invention, the locking component is slidably disposed within the side impact protection block.

[0008] According to one embodiment of the present invention, the side impact protection mechanism further includes a fixed base that is fixedly attached to the side. The fixed base includes a locking portion, the locking portion is configured to engage detachably with the locking component, and when the locking component is in the locking position, the locking component engages with the locking portion.

[0017] According to one embodiment of the present invention, the operating component includes a contact end and an operating end that moves away from the contact end. The contact end is connected to the locking component, and when the operating end is operated, the operating end drives the operating component so that the operating component rotates and moves the locking component toward the release position in a direction away from the side by the contact end.

[0018] According to one embodiment of the present invention, the width of the operating component gradually increases from the contact end toward the operating end.

[0019] According to one embodiment of the present invention, the side impact protection block is provided with a chamber and one or more openings communicating with the chamber. The operating component is partially housed within the chamber. The operating end includes an outwardly projecting arc-shaped structure positioned at a location corresponding to one or more of the openings, and a projection, the projection protruding from the outwardly projecting side of the outwardly projecting arc-shaped structure and positioned within one or more of the openings.

[0020] According to one embodiment of the present invention, the protruding portion is provided with at least one protruding rib.

[0021] According to one embodiment of the present invention, the side impact protection mechanism further includes a regulating component disposed within the side impact protection block, the regulating component preventing the movement of the locking component when the locking component is in the released position.

[0022] According to one embodiment of the present invention, the locking component is provided with a positioning portion, and when the locking component is in the release position, the restricting component contacts the positioning portion to prevent the locking component from moving.

[0023] According to one embodiment of the present invention, when the operating part is pressed, the operating part rotates, drives the locking part, and moves it toward the release position in a direction away from the side.

[0024] According to an embodiment of the present invention, the locking component includes a pressed inclined surface inclined with respect to the moving direction of the locking component. When the operating component is pushed, the operating component rotates, presses the pressed inclined surface, and moves the locking component toward the release position along the direction away from the side.

[0025] According to an embodiment of the present invention, the operating component includes a pressing inclined surface configured to cooperate with the pressed inclined surface to move the locking component toward the release position along the direction away from the side.

The rotating end portion is rotatably connected to the side impact protection block, and the pressing inclined surface is located at the free end portion.

[0027] According to an embodiment of the present invention, the operating component is slidably disposed within a cavity of the side impact protection block.

[0028] According to an embodiment of the present invention, the operating component slidably drives the locking component to move toward the release position.

[0029] According to an embodiment of the present invention, the moving direction of the operating component and the moving direction of the locking component are opposite directions.

[0030] According to an embodiment of the present invention, the side impact protection mechanism further includes a connecting component. A first end portion of the connecting component is attached to the operating component. A second end portion of the connecting component is attached to the locking component, and when the operating component moves, the operating component drives the connecting component to rotate to move the locking component toward the release position.

[0031] According to an embodiment of the present invention, the connecting component is disposed between the operating component and the locking component.

[0032] According to one embodiment of the present invention, the first end of the connecting component includes a first leg and a second leg. The first leg and the second leg are slidably arranged on the operating component. The sliding direction of the first leg is perpendicular to the sliding direction of the second leg and parallel to the direction of movement of the operating component. When the operating component moves, the sliding movement of the first leg relative to the operating component and the sliding movement of the second leg relative to the operating component drive the connecting component to rotate relative to the side impact protection block.

[0033] According to one embodiment of the present invention, the operating component is provided with a first slide groove and a second slide groove. The longitudinal direction of the first slide groove is perpendicular to the longitudinal direction of the second slide groove and parallel to the direction of movement of the operating component, and the first leg and the second leg penetrate the first slide groove and the second slide groove, respectively, and are slidable along the longitudinal direction of the first slide groove and the longitudinal direction of the second slide groove, respectively.

[0034] According to one embodiment of the present invention, the second end of the connecting component includes a third leg portion. The third leg portion is slidably positioned on the locking component. The sliding direction of the third leg portion is perpendicular to the direction of movement of the locking component, and when the connecting component rotates, the connecting component drives the locking component to move using the third leg portion.

[0035] According to one embodiment of the present invention, the locking component is provided with a third slide groove. The longitudinal direction of the third slide groove is perpendicular to the direction of movement of the locking component, and the third leg portion penetrates the third slide groove and is slidable along the longitudinal direction of the third slide groove.

[0036] According to one embodiment of the present invention, the operating component includes two positioning arms, and the locking component is positioned between the two positioning arms.

[0037] According to one embodiment of the present invention, the side impact protection mechanism further includes a positioning column disposed within the side impact protection block. The locking component is provided with a through hole, and the positioning column passes through the through hole.

[0038] According to one embodiment of the present disclosure, the side impact protection mechanism is mounted on the base of a child seat, which includes a seat that is detachably attached to or fixed to the base.

[0039] According to one embodiment of the present invention, the side impact protection mechanism is mounted on the seat of a child seat, which includes a base that is detachably attached to or fixed to the seat.

[0040] According to one embodiment of the present invention, the direction of movement of the locking component is parallel to the longitudinal direction of the side impact protection block.

[0041] According to one embodiment of the present invention, the direction of movement of the locking component is perpendicular to the longitudinal direction of the side impact protection block 1.

[0042] According to one embodiment of the present invention, when the operating part is pressed, the operating part rotates and drives the locking part to move toward the release position along a direction parallel to the lateral surface.

[0043] In contrast to the prior art, in this disclosure, when the side impact protection block is in the deployed position, the locking component can be driven to move to the locked position so as to prevent the side impact protection block from rotating laterally and moving away from the deployed position. On the other hand, when it is desired to fold the side impact protection block, the operating component can be operated to move the locking component to the released position, thereby allowing the side impact protection block to rotate laterally from the deployed position to the folded position. Thus, this disclosure is simple in structure and easy to operate.

[0044] These and other objects of the present disclosure will become apparent to those skilled in the art by reading the following detailed description of preferred embodiments shown in each drawing.

[0045] The present disclosure will be further illustrated below with reference to the attached drawings. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0047] In the following detailed description of preferred embodiments, reference is made to accompanying drawings illustrating specific embodiments that form part of the present disclosure and enable the implementation of the present invention. Herein, terms indicating direction, such as “up,” “down,” “right,” “left,” “front,” and “back,” are used with reference to the orientation of the drawings being described. The components of the present disclosure can be arranged in several different orientations. Therefore, terms indicating direction are used for illustrative purposes only and are not limiting. Accordingly, the drawings and description should be considered essentially illustrative and not limiting. Also, the terms “joining” or “connecting” are intended to mean either indirect or direct mechanical connection. Thus, when a first device is joined or connected to a second device, the connection may be by direct mechanical connection or by indirect mechanical connection through other devices and connections.

[0048] To illustrate the technical specifications and structural features of this disclosure, as well as the objectives and effects to be achieved, relevant embodiments and drawings are described below.

[0049] Unless otherwise stated or the context requires, any reference to a typical embodiment of the side impact protection mechanism 10 should be understood to mean and include any and all embodiments of the side impact protection mechanisms 10-10c, respectively.

[0050] Referring to Figures 1 to 5, Figures 1 and 2 are schematic diagrams showing different states of the child seat 100 according to the first embodiment of the present disclosure. Figure 3 is a partial internal configuration diagram of the side impact protection mechanism 10 according to the first embodiment of the present disclosure. Figure 4 is a partial diagram of the side impact protection mechanism 10 according to the first embodiment of the present disclosure. Figure 5 is a cross-sectional view of the side impact protection mechanism 10 according to the first embodiment of the present disclosure along line A-A shown in Figure 3. As shown in Figures 1 to 5, an exemplary or representative child seat 100 is a child carrier installed on a vehicle seat of a vehicle, for example, on a vehicle seat (or passenger seat) of an automobile, and includes two side impact protection mechanisms 10, a seat 20, and a base 30. The base 30 can be secured to the vehicle seat by vehicle belts or an International Organization for Standardization FIX (ISOFIX) device. The seat 20 is removablely mounted or secured on the base 30, and the child sits in it. The two side impact protection mechanisms 10 are positioned on two opposing sides 21 of the seat 20 to cushion side impacts from any lateral direction and to provide better protection to the child during a side impact. However, the number and form of side impact protection mechanisms according to this disclosure are not limited to this embodiment. Those skilled in the art will recognize that countless other designs are available and substantially equivalent, as shown in various figures, not limited to these examples. For example, in another embodiment, the child seat may include only one side impact protection mechanism positioned on one of the sides of the seat. In another embodiment, the child seat may include at least one side impact protection mechanism positioned on at least one side of the base. In yet another embodiment, the side impact protection mechanism may also be positioned on the side of any other part of any other child carrier, for example, the side impact protection mechanism may be positioned on the side of one of the seat portion and frame of a stroller, or on the side of the carrycot body of a child carrycot.

[0051] Referring to Figures 1 and 2, typical embodiments of two side impact protection mechanisms 10 arranged on the child seat 100 are shown. The two side impact protection mechanisms 10 located on opposite sides have symmetrically identical structures, so the description of one side impact protection mechanism 10 is given below. Specifically, the side impact protection mechanism 10 includes a side impact protection block or housing 11 that is rotatably connected to the side 21 and can be switched between a folded position or configuration as shown in Figure 2 and an unfolded position or configuration as shown in Figure 1 relative to the side 21. When the child seat 100 is installed on the vehicle seat, the side impact protection block 11 can be unfolded from the folded position to the unfolded position such that the side impact protection block 11 protrudes at least partially from the side 21 along the lateral direction. In the event of a side impact, the side impact protection block 11, which protrudes at least partially from the side 21 along the lateral direction, can first impact with the vehicle body, and then the seat 20 or base 30 can cushion the side impact by transmitting the side impact acting on the side impact protection block 11 to another location, preventing the side impact or energy from directly acting on the child seated in the child seat 100, and thus better protecting the child during a side impact. On the other hand, when the side impact protection block 11 is folded from the deployed position to the folded position, the side impact protection block 11 can be in close contact with the side 21, reducing the space occupied by the child seat 100 and making storage and transport easier.

[0052] In a first representative embodiment of the side impact protection mechanism 10, the side impact protection block 11 includes a fitting surface 112 and a pressing surface 113 facing the fitting surface 112. The fitting surface 112 is configured to be in close contact with the side 21 when the side impact protection block 11 is in the folded position, thus allowing the structure of the child seat 100 to be more compact. The pressing surface 113 is also provided with an arc-shaped or curved recess to allow the user's palm to partially align with it when the user pushes and rotates the side impact protection block 11, providing comfortable operation.

[0053] As shown in Figures 3 to 5, the side impact protection mechanism 10 further includes an operating part 12 and a locking part 13. The locking part 13 is at least partially located within the side impact protection block 11 and is switchable (or movable) between a first locking position or configuration and a second release position or configuration relative to the side impact protection block 11. Those skilled in the art will recognize the numerous variations in how the locking part 13 may be located on the side impact protection block 11 (for example, the locking part 13 may be at least partially or substantially located within the side impact protection block 11, but not limited thereto), and all such variations are considered equivalent within the scope of this disclosure. The direction of movement of the locking part 13 is parallel to the longitudinal direction of the side impact protection block 11. When the locking part 13 is in the locking position, the side impact protection block 11 is prevented from rotating laterally 21 away from the deployed position. When the locking part 13 is in the release position, the side impact protection block 11 can rotate laterally 21 from the deployed position to the folded position. The operating component 12 is movably or at least partially positioned within the side impact protection block 11 and is configured to move the locking component 13 toward a release position operated by the user. In this embodiment, the direction of movement of the locking component 13 is parallel to the longitudinal direction of the side impact protection block 11. When the side impact protection block 11 is in the deployed position, the locking component 13 can be driven to move toward the locked position along a direction toward the side 21, thereby preventing the side impact protection block 11 from rotating toward the side 21 away from the deployed position. On the other hand, when it is desired to fold the side impact protection block 11, the side impact protection block 11 can be rotated from the deployed position to the folded position toward the side 21 by operating the operating component 12 to move the locking component 13 toward the release position along a direction toward the side 21. Thus, the present disclosure is simple in structure and easy to operate. Side collisions and side impacts refer to collisions or impacts from the side of the child seat 100 or the vehicle, and typically act on the end of the side impact protection block 11 that is away from the side 21.

[0054] More specifically, the locking component 13 is slidably positioned on (or nearly within) the side impact protection block 11, thereby allowing the locking component 13 to switch or move quickly and smoothly between a locked position and an unlocked position.

[0055] As shown in Figures 1 to 5, the side impact protection mechanism 10 further includes a fixed base 14 that is permanently attached to the side 21. The fixed base 14 is at least partially cylindrical and includes a locking portion or groove 141 configured to removably engage with a locking component 13. The fixed base 14 may also be of any of countless shapes and sizes. When the locking component 13 is in the locked position, it engages with the locking portion 141, preventing the side impact protection block 11 from rotating away from its deployed position relative to the side 21. Specifically, the locking component 13 is aligned with the locking portion 141 when the side impact protection block 11 is in the deployed position. This allows the locking component 13 to engage with the locking portion 141 accurately and quickly when the side impact protection block 11 is in the deployed position, preventing the side impact protection block 11 from rotating away from its deployed position relative to the side 21. Furthermore, when it is desired to fold the side impact protection block 11, the locking component 13 can be driven by the operating component 12 to quickly disengage from the locking portion 141, thereby allowing the side impact protection block 11 to rotate from the deployed position to the folded position relative to the side 21. In this embodiment, the locking portion 141 may be a hole structure, and the locking component 13 may be a plate-shaped or rod-shaped structure. However, this disclosure is not limited to this embodiment.

[0056] Furthermore, the side impact protection mechanism 10 further includes at least one reset component 15 (or first elastic component) positioned between the tip 134 of the locking component 13 and the side impact protection block 11, configured to engage the locking component 13 with the locking portion 141. That is, when the side impact protection block 11 reaches the deployed position, the locking portion 141 and the base end 133 of the locking component 13 are aligned with each other, so the reset component 15 can drive the locking component 13 to engage with the locking portion 141. When the side impact protection block 11 has not reached the deployed position, the locking portion 141 and the locking component 13 are not aligned with each other, so the reset component 15 can only bring the locking component 13 into contact with the outer wall of the base 14. Specifically, at least one protruding mounting post 131 extends protruding from the tip 134 of the locking component 13, and the reset component 15 is mounted around the protruding mounting post 131, so that the reset component 15 can be stably positioned between the tip 134 of the locking component 13 and the side impact protection block 11, where the length of the protruding mounting post 131 may be shorter than the length of the reset component 15, thereby providing a space that is compressed within the side impact protection block 11 when in the released position. In this embodiment, the reset component 15 may be a compression spring. However, the disclosure is not limited to this embodiment. For example, in another embodiment, the reset component may be a torsion spring, a helical coil spring, or a magnetic structure.

[0057] As shown in Figures 3 to 5, a sliding passage or channel 111 is provided inside the side impact protection block 11. The locking component 13 is slidably positioned on the sliding passage 111. The sliding passage 111 prevents the locking component 13 from swinging or vibrating relative to the side impact protection block 11, and ensures that the locking component 13 slides stably and smoothly.

[0058] Furthermore, in order to move the locking component 13 toward the release position by the operating component 12 in a limited mechanical space, the direction of movement of the operating component 12 can differ from the direction of movement of the locking component 13. As shown in Figures 3 to 5, the operating component 12 of the first embodiment is rotatably mounted on the side impact protection block 11. Thus, the user can rotate the operating component 12 by toggling it, thereby driving the operating component 12 to move the locking component 13 toward the release position 14. Specifically, when the operating component 12 is toggled, the operating component 12 rotates and drives the locking component 13 toward the release position along the direction away from the side 21. More specifically, the operating component 12 includes a contact end 121, an operating end 122 away from the contact end 121, and a rotating portion 125. The rotating portion 125 is rotatably connected to the side impact protection block 11 via a rotating pin 126. Those skilled in the art will recognize that the pivot 125 may be connected to the side impact protection block 11 and / or the pivot pin 126 in many different ways and with many different types of movement, all of which are equivalent and considered to be within the scope of the present disclosure. The contact end 121 and the operating end 122 are located on two opposing sides of the pivot 125, with the exemplary operating end 122 abutting against the side wall of the side impact protection block 11. The contact end 121 is at least partially coupled to a recess 135 of the locking component 13. When the operating end 122 is toggled, the operating end 122 drives the operating component 12, which moves the locking component 13 toward the release position along the direction away from the side 21 by the contact end 121. In a first typical embodiment, the width of the operating component 12 can gradually increase from the contact end 121 toward the operating end 122, as a result of easily coupling the contact end 121 to the locking component 13. In some examples, the operating part 12 of the first embodiment may have a circular sector shape factor, but the operating part 12 may have any of the countless other different shapes such as square, rectangular, or cross-shaped. However, as described below, in a typical locked or unlocked position, the operating part 12 should be rotatably moved via at least a portion of the internal side impact protection block 11 for such type of operating part 12.

[0059] As shown in Figures 3 to 5, the side impact protection block 11 has a chamber 116, a first opening 114 of the side impact protection block 11 communicating with the chamber 116, and a second opening 1161 of the chamber 16 aligned with the first opening 114 of the side impact protection block 11. The operating part 12 is at least partially housed within the chamber 116. The operating end 122 includes an outwardly projecting arc-shaped or C-shaped structure 123 positioned corresponding to the openings 114 and 1161. The projection 124 protrudes from the outwardly projecting side of the outwardly projecting arc-shaped structure 123 and is located within the openings 114 and 1161. To prevent the operating part 12 from exiting the chamber 116 through the openings 114 and 1161, the size of the outwardly projecting arc-shaped structure 123 may be larger than the size of the openings 114 and 1161. The operating part 12 can be driven to rotate by the projection 124 when the projection 124 is toggled from the released position to the locked position and / or vice versa. Specifically, at least one projection rib protrudes from the projection 124 to increase friction between the projection 124 and the user's finger to facilitate the toggle operation. The side impact protection mechanism 10 also further includes a regulating part 115 located within the side impact protection block 11 to prevent a reset delay of the locking part 13 caused by excessive movement of the locking part 13. In some examples, the regulating part 115 protrudes from the pressing surface 113 within the chamber 116. When the locking part 13 is in the released position, the regulating part 115 can block the locking part 13, restricting it from moving further away from the side 21, and position (or hold, or maintain) the locking part 13 in the released position. More specifically, a positioning part 132 is provided on the locking part 13. The restricting component 115 can abut against the positioning portion 132 to prevent the movement of the locking component 13 when the locking component 13 is in the released position. When the locking component 13 is in the released position, the restricting component 115 abuts against the positioning portion 132 and prevents the movement of the locking component 13, so that the locking component 13 can move stably between the locked position and the released position relative to the side impact protection block 11. In this embodiment, the positioning portion 132 may be a hole structure.However, this disclosure is not limited to these embodiments.

[0060] The operation of the side impact protection mechanism 10 according to this embodiment is described below. When the user wants to fold the side impact protection block 11, they can drive the operating part 12 to rotate by toggling the protrusion 124 along the toggle direction F1, as shown in Figure 3. When the operating part 12 rotates, the operating part 12 can move the locking part 13 toward the release position along the direction away from the side 21 by the contact end 121, thereby driving the locking part 13, elastically deforming or compressing the reset part 15 to disengage from the locking part 141, and allowing the side impact protection block 11 to rotate relative to the side 21 and move away from the deployed position shown in Figure 1. The user can then operate the side impact protection block 11 and rotatably fold it relative to the side 21 from the deployed position shown in Figure 1 to the folded position shown in Figure 2. Furthermore, when the user wants to deploy the side impact protection block 11, they can rotatably deploy the side impact protection block 11 from the folded position to the deployed position. If the side impact protection block 11 has not yet reached the deployed position, the locking component 13 is not aligned with the locking portion 141, so the elastically deformed reset component 15 can only bring the locking component 13 into contact with the outer wall of the fixed base 14. When the side impact protection block 11 reaches the deployed position, the locking component 13 is aligned with the locking portion 141 and does not come into contact with the outer wall of the fixed base 14. Therefore, the elastically deformed reset component 15 engages the locking component 13 with the locking portion 141, suppresses the side impact protection block 11 from rotating away from the deployed position relative to the side 21, positions the locking component 13 in the deployed position, and can cushion the side impact during a side impact.

[0061] Furthermore, referring to Figures 6 to 9, Figure 6 is a diagram showing the side impact protection mechanism 10a according to the second embodiment of this disclosure. Figure 7 is a cross-sectional view of the side impact protection mechanism 10a according to the second embodiment of this disclosure along the line B-B shown in Figure 6. Figure 8 is a cross-sectional view showing the operating part 12a in the side impact protection mechanism 10a according to the second embodiment of this disclosure in a pressed state. Figure 9 is a partial view of the side impact protection mechanism 10a according to the second embodiment of this disclosure. As shown in Figures 6 to 9, the side impact protection mechanism 10a of this embodiment has the same structure as the side impact protection mechanism 10 of the first embodiment.

[0062] For the sake of simplicity, a description of similar structures will be omitted here. The differences between the side impact protection mechanism 10a of this embodiment and the side impact protection mechanism 10 of the first embodiment are as follows.

[0063] (1) The operating part 12a is configured to rotate when pressed, moving the locking part 13a to the release position in a direction away from the side 21.

[0064] (2) The locking component 13a has a pressable inclined surface 132a that is inclined with respect to the direction of movement of the locking component 13a. When the operating component 12a is pressed, the operating component 12a rotatably presses the pressable inclined surface 132a, driving the locking component 13a to move toward the release position along the direction away from the side 21. In this embodiment, the pressable inclined surface 132a is located adjacent to at least one protruding mounting column 131a. However, this disclosure is not limited to this embodiment.

[0065] (3) The operating part 12a includes a pressing inclined surface 121a configured to cooperate with the pressed inclined surface 132a to move the locking part 13a toward the release position along a direction away from the side 21.

[0066] (4) The operating part 12a further includes a rotating end 122a and a free end 123a. The rotating end 122a is rotatably connected to the side impact protection block 11a. The pressing inclined surface 121a is located at the free end 123a.

[0067] A typical second embodiment of the side impact protection mechanism 10a is described below. When the side impact protection block 11a is to be folded, the user can rotate the operating part 12a so that it partially enters the side impact protection block 11a by pressing the free end 123a of the operating part 12a along the pressing direction F2, as shown in Figure 7. A typical operating part 12a may further include a protrusion or head portion 124a adjacent to the pressing inclined surface 121a. As the operating part 12a rotates and partially enters the side impact protection block 11a, the pressing inclined surface 121a presses against the pressed inclined surface 132a, moving the locking part 13a toward the release position along the direction away from the side 21 relative to the slide passage 111a, thereby driving the locking part 13a, elastically deforms at least one reset part 15a, disengaging it from the locking portion 141a of the fixed base 14a, and rotating the side impact protection block 11a away from the deployed position relative to the side 21. In some examples, as the pressing inclined surface 121a presses against the pressed inclined surface 132a, one or more openings 136a of the locking part 13a may be adjacent to (or separated from) the pressed inclined surface 132a. The user can then place their hand in the arc-shaped recess of the pressing surface 113a and bring the fitting surface 112a of the side impact protection block 11a into close contact with the side 21. Furthermore, if the user wishes to deploy the side impact protection block 11a, the user can rotatably deploy the side impact protection block 11a from the folded position to the deployed position. If the side impact protection block 11a has not yet reached the deployed position, the locking component 13a is not aligned with the locking portion 141a, so the elastically deformed reset component 15a can only bring the locking component 13a into contact with the outer wall of the fixed base 14a. When the side impact protection block 11a reaches the deployed position, the locking component 13a is aligned with the locking portion 141a and is not in contact with the outer wall of the fixed base 14a, so the elastically deformed reset component 15a is not in contact with the outer wall of the fixed base 14a, allowing the locking component 13a to engage with the locking portion 141a, suppressing the side impact protection block 11a from rotating away from the deployed position relative to the side 21, positioning the locking component 13a in the deployed position, and mitigating the side impact during a side impact.

[0068] Referring further to Figures 10 to 14, Figure 10 is a diagram showing the side impact protection mechanism 10b according to the third embodiment of this disclosure. Figure 11 is a cross-sectional view of the side impact protection mechanism 10b according to the third embodiment of this disclosure along the line C-C shown in Figure 10. Figure 12 is a cross-sectional view showing the operating part 12b of the side impact protection mechanism 10b according to the third embodiment of this disclosure in a pressed state. Figure 13 is a partial view of the side impact protection mechanism 10b according to the third embodiment of this disclosure. Figure 14 is a diagram showing the operating part 12b and connecting part 16b according to the third embodiment of this disclosure. As shown in Figures 10 to 14, the side impact protection mechanism 10b of this embodiment has the same structure as the side impact protection mechanism 10 of the first embodiment. Here, for the sake of simplification, a description of the similar structure will be omitted. The differences between the side impact protection mechanism 10b of this embodiment and the side impact protection mechanism 10 of the first embodiment are as follows.

[0069] (1) The operating part 12b is slidably positioned on the side impact protection block 11b and is configured to press to drive the locking part 13b to a released position slidably along the direction away from the side 21, the sliding direction of the operating part 12b being opposite to the direction of movement of the locking part 13b. In this embodiment, when the operating part 12b slides along the direction toward the side 21, the operating part 12b drives the locking part 13b to a released position, which will be described in more detail below. However, this disclosure is not limited to this embodiment.

[0070] (2) The side impact protection mechanism 10b further includes a connecting component 16b. At least one first end or lower end 164b of the connecting component 16b is attached to the operating component 12b. At least one second end or upper end 165b of the connecting component 16b is attached to the locking component 13b. When the operating component 12b moves, the operating component 12b rotates the connecting component 16b, causing the locking component 13b to move toward the release position 14. Specifically, the connecting component 16b is positioned between the operating component 12b and the locking component 13b. More specifically, the first end 164b of the connecting component 16b includes a first leg 161b and a second leg 162b. The first leg 161b and the second leg 162b are slidably mounted on the operating component 12b. The sliding direction of the first leg portion 161b is perpendicular to the sliding direction of the second leg portion 162b and parallel to the direction of movement of the operating component 12b. The connecting component 16b can be driven to rotate relative to the side impact protection block 11b by the sliding movement of the first leg portion 161b relative to the operating component 12b and the sliding movement of the second leg portion 162b relative to the operating component 12b when the operating component 12b moves.

[0071] (3) The operating part 12b is provided with a first slide groove 121b and a second slide groove 122b. The longitudinal direction of the first slide groove 121b is perpendicular to the longitudinal direction of the second slide groove 122b and parallel to the direction of movement of the operating part 12b. The lateral direction of the second slide groove 122b is perpendicular to the longitudinal direction of the first slide groove 121b. The first leg portion 161b penetrates the first slide groove 121b and is slidable along the longitudinal direction of the first slide groove 121b, and the second leg portion 162b penetrates the second slide groove 122b. The second end portion 165b of the connecting part 16b includes a third leg portion 163b that is slidably positioned on the locking part 13b. The sliding direction of the third leg portion 163b is perpendicular to the direction of movement of the locking part 13b. When the connecting part 16b rotates, the connecting part 16b can drive the locking part 13b by the third leg portion 163b. The third slide groove 123b is provided in the locking part 13b. The longitudinal direction of the third slide groove 123b is perpendicular to the direction of movement of the locking part 13b. The third leg portion 163b penetrates the third slide groove 123b and is slidable along the longitudinal direction of the third slide groove 123b.

[0072] (4) The operating component 12b includes two positioning arms 124b. The locking component 13b is positioned between the two positioning arms 124b.

[0073] (5) The side impact protection mechanism 10b further includes a positioning column 114b positioned on the side impact protection block 11b. The locking component 13b is provided with a through hole 132b. The positioning column 114b passes through the through hole 132b. In this embodiment, the through hole 132b is located adjacent to at least one protruding mounting column 131b. However, this disclosure is not limited to this embodiment.

[0074] The operation of the side impact protection mechanism 10b according to this embodiment is described below. When the side impact protection block 11b is to be folded, the user can move the operating part 12b along the pushing direction F3, as shown in Figure 11, thereby moving the operating part 12b toward the side 21 and rotating the connecting part 16b. In some examples, the operating part 12b is slidably positioned within the cavity (or chamber) 116b of the side impact protection block 11b. When the connecting part 16b rotates, the connecting part 16b moves the locking part 13b toward the release position toward the side 21 relative to the sliding passage 111b, thereby driving the locking part 13b to elastically deform at least one reset part 15b, disengaging it from the locking part 141b of the fixed base 14b, and rotating the side impact protection block 11b toward the deployed position toward the side 21. The user can then place their hand in the arc-shaped recess of the pressing surface 113b, and then push the side impact protection block 11b, allowing it to rotatably fold from the deployed position to the folded position relative to the side 21, thereby bringing the mating surface of the side impact protection block 11b into close contact with the side 21. Furthermore, if the user wishes to deploy the side impact protection block 11b, they can rotatably deploy the side impact protection block 11b from the folded position to the deployed position. If the side impact protection block 11b has not yet reached the deployed position, the locking part 13b will not align with the locking part 141b, so the elastically deformed reset part 15b can only drive the locking part 13b and bring it into contact with the outer wall of the fixed base 14b. When the side impact protection block 11b reaches the deployed position, the locking component 13b is aligned with the locking portion 141b and is not in contact with the outer wall of the fixed base 14a. Therefore, the elastically deformed reset component 15b can engage the locking component 13b with the locking portion 141b, preventing the side impact protection block 11b from rotating away from the deployed position relative to the side 21, positioning the locking component 13b in the deployed position, and mitigating the side impact during a side impact.

[0075] Furthermore, referring to Figures 15 to 21, Figure 15 is a partial view of the child seat 100c (having arbitrary load legs and no attachable seat) according to the fourth embodiment of the present disclosure. Figure 16 is another partial view of the child seat 100c according to the fourth embodiment of the present disclosure. Figures 17 to 19 are partial views of the side impact protection mechanism 10c according to the fourth embodiment of the present disclosure. Figure 20 is a cross-sectional view of the side impact protection mechanism 10c according to the fourth embodiment of the present disclosure along the line D-D shown in Figure 17. Figure 21 is a cross-sectional view showing the operating part 12c of the side impact protection mechanism 10c according to the fourth embodiment of the present disclosure in a pressed state. As shown in Figures 15 to 21, the side impact protection mechanism 10c of this embodiment has a similar structure to the side impact protection mechanism 10 of the first embodiment. Here, for simplicity, a description of the similar structure is omitted. The differences between the side impact protection mechanism 10c of this embodiment and the side impact protection mechanism 10 of the first embodiment are as follows.

[0076] (1) The side impact protection mechanism 10c is located on the side 21c of the base 30c of the child seat 100c. The side impact protection block 11c of the side impact protection mechanism 10c is rotatably connected to the side 21c by a pivot rod 17c. The side impact protection mechanism 10c includes an elastic component 18c (or a second elastic component) located between the side impact protection block 11c and the side 21c to drive the side impact protection block 11c back to the folded position when the locking component 13c is in the released position. The elastic component 18c is annularly mounted on the pivot rod 17c. The direction of movement of the locking component 13c intersects the longitudinal direction of the side impact protection block 11c. In this embodiment, the direction of movement of the locking component 13c is substantially parallel to the side of the side 21c. However, this disclosure is not limited to this embodiment.

[0077] (2) The side impact protection mechanism 10c further includes a connecting component 16c slidably disposed on the side impact protection block 11c. The sliding direction of the connecting component 16c intersects with the direction of movement of the locking component 13c. The operating component 12c is rotatably connected to the side impact protection block 11c. The operating component 12c drives the connecting component 16c to move the locking component 13c toward the release position.

[0078] (3) The first end of the connecting component 16c includes a drive inclined surface 161c. A protruding column 131c protrudes from the locking component 13c. The direction of protrusion of the protruding column 131c intersects (or extends perpendicularly to) the direction of movement of the locking component 13c. The protruding column 131c is configured to cooperate with the drive inclined surface 161c, so that the locking component can be driven to move by the cooperation of the drive inclined surface 161c and the protruding column 131c when the connecting component 16c slides.

[0079] (4) The second end of the connecting component 16c includes the inclined structure 162c. When the operating component 12c is pressed to rotate, the operating component 12c can push the inclined structure 162c and drive the connecting component 16c to slide.

[0080] (5) The locking portion 141c of the fixed base 14c is substantially aligned with the locking component 13c along the vertical direction when the side impact protection block 11c is in the deployed position. In this embodiment, the locking portion 141c is a straight-hole structure extending along the vertical direction. However, this disclosure is not limited to this embodiment.

[0081] (6) The locking part 13c has an elongated hole 132c that passes through it. The longitudinal direction of the elongated hole 132c is parallel to the direction of movement of the locking part 13c. The rotating rod 17c passes through the elongated hole 132c. At least one resetting part 15c is positioned within the elongated hole 132c and between the rotating rod 17c and the locking part 13c.

[0082] The operation of the side impact protection mechanism 10c according to this embodiment is described below. When the user wants to fold the side impact protection block 11c, as shown in Figure 20, the user can drive the operating part 12c to push the inclined structure 162c by pressing the operating part 12c along the pressing direction F4, thereby moving the connecting part 16c in a direction away from the side 21c. When the connecting part 16c moves in a direction away from the side 21c, the connecting part 16c can move the locking part 13c in cooperation with the driving inclined surface 161c and the protruding column 131c, driving the locking part 13c to elastically deform the reset part 15c, disengaging it from the locking part 141c of the fixed base 14c, and rotating the side impact protection block 11c away from the deployed position relative to the side 21c. Then, the elastic part 18c drives the side impact protection block 11c, allowing it to be rotatably folded from the deployed position to the folded position relative to the side 21c.

[0083] When the user wants to deploy the side impact protection block 11c, they can rotate and deploy the side impact protection block 11c from the folded position to the deployed position by elastically deforming the elastic component 18c. If the side impact protection block 11c has not yet reached the deployed position, the locking component 13c is not aligned with the locking portion 141c, so the elastically deformed reset component 15c can only bring the locking component 13c into contact with the outer wall of the fixed base 14c. When the side impact protection block 11c reaches the deployed position, the locking component 13c is aligned with the locking portion 141c and is not in contact with the outer wall of the fixed base 14c, so the elastically deformed reset component 15c can engage the locking component 13c with the locking portion 141c, preventing the side impact protection block 11c from rotating away from the deployed position relative to the side 21c, positioning the locking component 13c in the deployed position, and mitigating the side impact during a side impact.

[0084] Compared to prior art, in this disclosure, when the side impact protection block is in the deployed position, the locking component can be driven to move to the locked position, thereby preventing the side impact protection block from rotating laterally away from the deployed position. On the other hand, when it is desired to fold the side impact protection block, the operating component can be operated to move the locking component to the released position, thereby allowing the side impact protection block to rotate laterally from the deployed position to the folded position. Therefore, this disclosure has a simple structure and is easy to operate.

[0085] Those skilled in the art will readily recognize that many modifications and changes to the apparatus and method can be made while retaining the teachings of this disclosure. Accordingly, the above disclosure should be construed as being limited only by the appended claims and boundaries.
