Description

Technical Field

[0001] The present disclosure relates to the field of baby products, and particularly to a child seat and its side impact protection mechanism.

Background Art

[0002] Child seats are mainly used in automobiles to protect the safety of children riding in them. Currently, child seats are widely applied. In daily life, side impacts often occur during automobile accidents. In order to protect children riding in automobiles from the side impact force during side impact accidents, various side impact protection mechanisms attached to the side portions of child seats have been developed.

[0003] Currently available side impact protection mechanisms generally include a locking release operation means, a locking device, and a side impact protection case. The conventional side impact protection case extends laterally from the side portion of the child seat in the use state and is flatly attached to the side portion of the child seat when not in use. When the conventional side impact protection case is in the use state, the locking release operation means can be operated to control the unlocking of the locking device, whereby the conventional side impact protection case extending laterally can be folded. The above conventional side impact protection mechanism has a complex structure and is thus difficult to fold efficiently when not in use.

[0004] Therefore, it is desirable to solve the above problems by providing an improved side impact protection mechanism with a simple structure that can be folded easily and quickly, and a child seat equipped with the above improved side impact protection mechanism.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The purpose of this disclosure is to provide a side impact protection mechanism that has a simple structure, can be folded quickly and conveniently, and can provide immediate protection for a child in a car during a side impact accident.

[0006] Another object of this disclosure is to provide a child car seat that has a simple structure and can be folded quickly and conveniently when not in use, but has a side impact protection mechanism that can provide immediate protection for a child in a car during a side impact accident. [Means for solving the problem]

[0007] To achieve the above objective, the side impact protection mechanism according to this disclosure is provided on a child seat to cushion the side impact force applied to the child seat in the event of a side impact accident. For this purpose, the side impact protection mechanism includes a side impact protection case and a locking part. The side impact protection case is rotatably connected to the side of the child seat and is switchable between a folded state in which the side impact protection case abuts flat against the side and an extended state in which the side impact protection case is separated from the side. The side impact protection case is held in the extended state by the locking part being locked to the side. The locking part is movably installed within the side impact protection case and has a locking end that is detachably engaged with the side, the locking end being fully locked to the side when the side impact protection case is in the extended state and subjected to a side impact force, and the locking end being partially locked to the side when the side impact protection case is in the extended state but not subjected to a side impact force. In the latter case, the locking end can be released from partial locking to the side when the side impact protection case is pushed to rotate relative to the side so as to switch from an unfolded state to a folded state.

[0008] Compared to conventional technology, the locking end of this disclosure fully locks to the side when the side impact protection case is deployed and subjected to a side impact force, so that the side impact protection case can be stably held in the deployed state, providing immediate protection to the user in the event of a side impact accident and ensuring safe use. On the other hand, when the side impact protection case is deployed but not subjected to a side impact force, the locking end is only partially locked to the side. In this case, the operator can completely release the partial locking of the locking end from the side by simply pushing the side impact protection case to rotate it manually against the side, without needing to operate a release mechanism. This effectively increases the speed at which the side impact protection case can be folded, making the folding procedure of the side impact protection case convenient and quick. Furthermore, since the side impact protection mechanism does not include a release mechanism that requires operator operation, the structure of the side impact protection mechanism can be effectively optimized and simplified.

[0009] Preferably, the locking portion of the present disclosure is slidably mounted within a side impact protection case.

[0010] Preferably, in this disclosure, the end of the locking portion that is separated from the locking end is the operating end, and the operating end is exposed from the side impact protection case.

[0011] Preferably, the working end according to this disclosure has a substantially arc-shaped outer end surface.

[0012] Preferably, the side impact protection mechanism of the present disclosure further includes a mounting portion that is fixedly attached to a child seat. The mounting portion includes a locking recess for removably engaging with a locking end, and the locking of the locking end to the side portion is achieved by the engagement of the locking end with the locking recess.

[0013] Preferably, in this disclosure, the locking portion is aligned with the locking recess when the side impact protection case is in the deployed state.

[0014] Preferably, the tip of the locking end according to the present disclosure is provided with an inclined structure, which aligns with the inner circumferential wall around the opening of the locking recess when the side impact protection case is deployed and not subjected to a side impact force.

[0015] Preferably, the locking recess in this disclosure is a slot.

[0016] Preferably, according to this disclosure, the interference fit between the operating end and the side impact protection case occurs when the side impact protection case is deployed and subjected to a side impact force.

[0017] Preferably, the interior of the side impact protection case of the present disclosure forms a sliding passage, and the locking portion is slidably installed within the sliding passage.

[0018] Preferably, in this disclosure, the slide passage includes a first passage section and a second passage section arranged in a stepped manner, wherein the diameter of the second passage section is larger than the diameter of the first passage section. The second passage section penetrates the side impact protection case with the operating end positioned within the second passage section.

[0019] Preferably, the locking portion of the present disclosure is slidably arranged along the same direction as the longitudinal extension of the side impact protection case.

[0020] Preferably, the side impact protection mechanism of the present disclosure further includes a positioning assembly attached to the side impact protection case and connected to a locking portion. The positioning assembly always holds the locking portion in a predetermined position within the side impact protection case when the side impact protection case is deployed and not subjected to a side impact force, and the locking end is always kept partially engaged with the side portion.

[0021] Preferably, the positioning assembly of the present disclosure has a tendency to drive the locking end to extend from the side impact protection case when the locking end is fully locked to the side portion.

[0022] Preferably, the positioning assembly of the present disclosure includes a mounting portion and an elastic portion located at an end of the mounting portion. The elastic portion is elastically arranged with respect to the mounting portion. The mounting portion is attached to the side impact protection case, and the elastic portion is attached to the locking portion by an interference fit method.

[0023] Preferably, a connecting through hole is provided in the locking portion of the present disclosure, and the elastic portion is pressed against the inner wall surface of the connecting through hole.

[0024] Preferably, a positioning column is provided in the side impact protection case of the present disclosure. The positioning column is inserted into the connecting through hole and penetrates the connecting through hole.

[0025] Preferably, the positioning assembly of the present disclosure is an elastic member arranged like the letter "m".

[0026] Preferably, the side impact protection case of the present disclosure has a contact surface for flat contact with the side portion and an inwardly extending concave pressing surface located on the opposite side of the contact surface.

[0027] To achieve the above object, the child seat according to the present disclosure includes a seat, a base, and the above side impact protection mechanism. The seat is attached to the upper part of the base, and the side impact protection case is rotatably connected to the side portion of the seat or the base.

[0028] Compared with the prior art, the child seat according to the present disclosure includes the above-described side impact protection mechanism. Therefore, during a side impact accident, the locking end of the side impact protection case in the deployed state is completely locked to the side portion, and the side impact protection case can be stably held in the deployed state. During a side impact accident, the side impact protection mechanism can immediately protect a child riding in the vehicle, and the safe use of the side impact protection mechanism can be ensured. Further, since the locking end of the side impact protection case in the deployed state is not completely locked to the side portion when there is no side impact, the locking end can be completely released from the partial locking to the side portion by manually pushing and rotating the side impact protection case with respect to the side portion, and there is no need to operate a locking release means. Therefore, the speed of folding the side impact protection mechanism is effectively increased, and the convenient and rapid folding procedure of the side impact protection mechanism is facilitated. Furthermore, since the side impact protection mechanism of the present disclosure does not include a locking release means that requires an operator's operation, the structure of the side impact protection mechanism can be effectively optimized and simplified.

[Figure 6] FIG. 6 is a cross-sectional view showing a state in which, when the child seat receives a side impact force, the locking portion of the side impact protection mechanism of FIG. 4 retreats into the side impact protection case, and the locking end of the locking portion is completely locked at a predetermined position. [Modes for carrying out the invention]

[0030] To facilitate understanding of the purpose, features, and effects of this disclosure, preferred embodiments and accompanying drawings are provided to illustrate this disclosure in detail. It should be understood that this disclosure can be implemented or applied in other embodiments, and that many changes and modifications can be made to the embodiments described without departing from the spirit of this disclosure, and that the preferred embodiments are illustrative and not intended to limit this disclosure in any way.

[0031] As shown in Figures 1 to 3, the child seat 100 according to this disclosure includes a side impact protection mechanism 10, a seat 20, and a base 30. The seat 20 is mounted on top of the base 30. The side impact protection mechanism 10 includes a side impact protection case 11 (details of which will be described later), which is rotatably connected to the side portion 21 of the seat 20. Preferably, the side impact protection mechanism 10 is provided on each of the two side portions 21 of the seat 20 to provide complete cushioning protection to a child sitting in the child seat 100, but is not limited to this. The side impact protection case 11 is switchable between a folded state in which it abuts flat against the side portion 21 (see Figure 3) and an unfolded state in which it is rotated away from the side portion 21 (see Figures 1 and 2). When the child seat 100 is in use, the side impact protection case 11 is rotated from the folded state to the unfolded state. When a child seat 100 with the side impact protection case 11 deployed is subjected to a side impact force during a side impact accident, the side impact force acts first on the side impact protection mechanism 10 instead of the child sitting in the child seat 100. The side impact force is then effectively directed outward through the seat 20 or base 30, cushioned, and provides good protection to the child in the child seat 100. When the child seat 100 is not in use, the side impact protection case 11 can be rotated and folded to make it contact the side portion 21 flat, reducing its occupied space and making storage of the child seat 100 more convenient. Depending on the actual usage needs, the side impact protection case 11 can also be rotatably connected to the side portion 21 by the base 30, thereby allowing the side impact protection mechanism 10 to adapt to different mounting environments and provide more appropriate protection. The child seat 100 of this disclosure can adopt currently available safety seat structures, which will not be described repeatedly here. Of course, in addition to being applicable to the child seat 100 described above, the side impact protection mechanism 10 can also be applied to other types of baby carriers and child carriers according to actual needs, without being limited to any particular use. Next, the side impact protection mechanism 10 will be described in more detail with reference to Figures 1 to 6.

[0032] First, referring to Figures 4 to 6, the side impact protection mechanism 10 further includes a locking portion 12 in addition to the side impact protection case 11 described above. The side impact protection case 11 is held in an unfolded state by the locking portion 12 being locked to the side portion 21. The locking portion 12 includes a locking end 121 that is movably installed within the side impact protection case 11 and is detachably engaged with the side portion 21. The locking end 121 is fully locked to the side portion 21 when the side impact protection case 11 is in an unfolded state and subjected to a side impact force. When the side impact protection case 11 is in an unfolded state but not subjected to a side impact force, the locking end 121 is partially locked to the side portion 21. In the latter case, the side impact protection case 11 is pushed to rotate relative to the side portion 21, which releases the locking end 121 from partial locking to the side portion 21, thereby allowing the side impact protection case 11 to switch from an unfolded state to a folded state. In other words, the locking end 121 is fully locked to the side portion 21 when the side impact protection case 11 is in the deployed state and subjected to a side impact force, thereby stably holding the side impact protection case 11 in the deployed state. The side impact protection mechanism 10 configured in this way provides immediate protection when a side impact accident occurs, thus ensuring safe use. Furthermore, when the side impact protection case 11 is in the deployed state but not subjected to a side impact force, the locking end 121 is not fully locked to the side portion 21, but only partially locked to the side portion 21. Therefore, the locking end 121 can be completely released from partial locking to the side portion 21 by manually rotating or pushing the side impact protection case 11 without needing to operate the locking release means. This effectively increases the folding speed of the side impact protection mechanism 10, making it easier and faster to fold. In addition, since the side impact protection mechanism 10 of this disclosure does not have a locking release means that requires operation, the main body structure is more simplified and optimized. The term "lateral impact force" used here refers to the impact force applied to the side of the child seat 100 that causes a frontal impact on the locking portion 12.Specifically, the locking portion 12 is slidably installed within the side impact protection case 11 and can be conveniently moved to quickly lock onto the side portion 21 in response to the side impact force during a side impact accident. More specifically, an operating end 122 is formed at the end of the locking portion 12 that is away from the locking end 121 and is exposed from the side impact protection case 11. When the child seat 100 is subjected to a side impact force in a side impact accident, the operating end 122 of the locking portion 12 is the first part that comes into contact with the vehicle body that is subjected to the side impact. At this point, the locking portion 12 is immediately pushed axially at the operating end 122 and retracts into the side impact protection case 11, thereby completely locking the locking end 121 onto the side portion 21, and the entire side impact protection case 11 is immediately locked in an deployed state in response to the side impact, ensuring safe use.

[0033] As shown in Figures 4 to 6, the locking portion 12 is slidably positioned along the same direction as the longitudinal extension of the side impact protection case 11. As shown in Figure 6, when the side impact protection mechanism 10 is subjected to a side impact force in a side impact accident, the side impact force forms a pressing force F2 acting on the locking portion 12 along the direction in which the locking portion 12 is slidable. This causes the locking portion 12 to retract into the side impact protection case 11 and quickly lock onto the side portion 21. To accommodate side impact forces that may be coming from different directions to the locking portion 12, the operating end 122 of the locking portion 12 has a substantially arc-shaped outer end surface. Of course, depending on the actual usage needs, the outer end surface of the operating end 122 may be a flat end surface or an irregularly curved surface, and is not particularly limited. Preferably, the side impact protection case 11 has a contact surface 112 for flat contact with the side portion 21 and an inwardly extending concave pressing surface 113 located opposite the contact surface 112. When the side impact protection case 11 is folded, the contact surface 112 is in flat contact with the side portion 21, making the structure of the child seat 100 more compact. When rotating the unfolded side impact protection case 11 back into the folded position, the operator can easily rotate the side impact protection case 11 by pressing their palm against the concave pressing surface 113.

[0034] Referring to Figures 1, 2, 4, and 6, the side impact protection mechanism 10 of the present disclosure further includes a fixing portion 13 that is fixedly attached to the child seat 100. The fixing portion 13 includes a locking recess 131 for detachably engaging with a locking end 121, and the locking of the locking end 121 to the side portion 21 is achieved by the engagement of the locking end 121 to the locking recess 131. The fixing portion is an independent member, and since the locking end 121 is locked to the side portion 21 by engaging with the locking recess 131 of the fixing portion 13, the fixing portion 13 provides a function to prevent the side portion 21 from adversely affecting its structure. Preferably, the locking end 121 extends only to a depth of 3 mm within the locking recess 131 when the side impact protection case 11 is deployed and not subjected to a side impact force, so that the locking end 121 is easily removable from the locking recess 131. It should be understood that the present disclosure is not limited to the above conditions. Depending on the actual usage needs, the locking end 121 may be configured to extend more deeply (e.g., 5 mm) into the locking recess 131, or to extend more shallowly (e.g., 2 mm) into the locking recess 131. Specifically, the locking portion 12 is aligned with the locking recess 131 when the side impact protection case 11 is deployed, so that the locking portion 12 can be quickly aligned with and engaged with the locking recess 131 when the side impact protection case 11 is deployed. For example, the locking recess 131 may be a slot, but is not limited thereto, and the locking portion 12 may be a plate or a shaft, but is not limited thereto. More specifically, the tip of the locking end 121 is provided with an inclined structure 1211 that aligns with the inner circumferential wall around the opening of the locking recess 131 when the side impact protection case 11 is deployed and not subjected to a side impact force. When the side impact protection case 11 is rotated, the inclined structure 1211 of the locking end 121 is slidably pressed against the inner circumferential wall around the opening of the locking recess 131, allowing the locking end 121 to smoothly release from partial locking to the locking recess 131, and thus enabling rapid release of the locking portion 12. The length of the inclined structure 1211 at the tip of the locking end 121 is preferably 1.5 mm, but is not limited thereto.Depending on the actual usage needs, the inclined structure 1211 may be a rounded edge structure formed at the tip of the locking end 121.

[0035] Referring to Figures 4 to 6, when the side impact protection case 11 is deployed and subjected to a side impact force, an interference fit occurs between the operating end 122 and the side impact protection case 11, preventing the locking portion 12 from completely retracting into the side impact protection case 11 and losing its normal function. Specifically, a sliding passage 111 is formed inside the side impact protection case 11 through which the locking portion 12 slides. The locking portion 12 is positioned within the sliding passage 111 without the risk of shaking within the side impact protection case 11, ensuring that the locking portion 12 slides stably and smoothly within the side impact protection case 11. More specifically, the sliding passage 111 includes a first passage portion 1111 and a second passage portion 1112 arranged in a stepped manner. The diameter of the second passage portion 1112 is larger than the diameter of the first passage portion 1111. The second passage section 1112 penetrates the side impact protection case 11 with the operating end 122 of the locking part 12 installed inside the second passage section 1112. When the side impact protection case 11 is subjected to a side impact force, the operating end 122 is pressed against the inner wall surface of the second passage section 1112. In other words, in the event of a side impact accident, the inner wall surface of the second passage section 1112 prevents the operating end 122 from completely retracting into the side impact protection case 11 and losing its normal function.

[0036] As shown in Figures 4 to 6, the side impact protection mechanism 10 of the present disclosure further includes a positioning assembly 14 attached to the side impact protection case 11 and connected to the locking portion 12. The positioning assembly 14 always holds the locking portion 12 in a predetermined position within the side impact protection case 11 when the side impact protection case 11 is in the deployed state and not subjected to a side impact force, thereby keeping the locking end 121 in a state of partial engagement with the side portion 21 at all times. Therefore, when the side impact protection case 11 is in the deployed state and not subjected to a side impact force, the locking portion 12 is always partially engaged with the locking recess 131, thereby allowing the locking portion 12 to be quickly released from the locking recess 131 by the side impact protection case 11, and allowing the side impact protection case 11 to be changed from the deployed state to the folded state each time the side impact protection case 11 is rotatably pushed to rotate. Specifically, the positioning assembly 14 tends to drive the locking portion 12 to extend from the side impact protection case 11 when the locking end 121 is fully locked to the side portion 21. That is, the positioning assembly 14 functions to restore or reset the locking portion 12 to a position extending from the side impact protection case 11 each time after a side impact for convenient use the next time. More specifically, the positioning assembly 14 includes a mounting portion 141 and an elastic portion 142 located at the end of the mounting portion 141. The elastic portion 142 is elastically positioned relative to the mounting portion 141, the mounting portion 141 is attached to the side impact protection case 11, and the elastic portion 142 is attached to the locking portion 12 in an interference fit manner. The positioning assembly 14 is simple in structure and easy to install. Depending on the actual use needs, the positioning assembly 14 may be other conventionally known springs for similarly achieving the positioning and resetting of the locking portion 12. Preferably, but not limited to, the mounting portion 141 is snapped to the side impact protection case 11 so that the positioning assembly 14 is securely attached to the side impact protection case 11 and can be easily attached to and detached from the side impact protection case 11.To facilitate the attachment of the elastic portion 142 to the locking portion 12 while an interference fit is formed between the elastic portion 142 and the locking portion 12, the locking portion 12 is provided with a connecting through-hole 123, and the elastic portion 142 is elastically pressed against the inner wall surface of the connecting through-hole 123. However, the disclosure is not particularly limited thereto. Depending on the actual use needs, the elastic portion 142 may be attached directly to the locking portion 12 in another manner, and the positioning and resetting of the locking portion 12 can be achieved in a similar manner. For example, the positioning assembly 14 may include two elastic portions 142 and be elastic members arranged like the letter "m". Alternatively, depending on the actual use needs, the positioning assembly 14 may be N-shaped or wavy, not particularly limited thereto. To prevent the locking portion 12 from completely detaching from the side impact protection case 11, a positioning column 114 is provided inside the side impact protection case 11 that is inserted into and passes through the connecting through-hole 123.

[0037] The operating principle of the child seat 100 of this disclosure will be explained below with reference to Figures 1 to 6. When it is necessary to fold the side impact protection case 11, the operator only needs to push the side impact protection case 11 in the direction indicated by arrow F1 in Figure 4. The side impact protection case 11 is initially in the unfolded state, and the locking end 121 of the locking portion 12 is only partially engaged with the locking recess 131. Therefore, when the side impact protection case 11 is pushed in direction F1, it rotates in the direction indicated by arrow B shown in Figure 5, causing the locking portion 12 to rotate with it. The inclined structure 1211 of the locking end 121, which presses against the inner circumferential wall of the opening of the locking recess 131, forces the locking portion 12 to extend outward so as to release the locking end 121 from partial engagement with the locking recess 131. This allows the side impact protection case 11 to be rotated from the unfolded state as shown in Figure 2, and then switched to the folded state as shown in Figure 3.

[0038] On the other hand, if the side impact protection case 11 is to be extended and used, the operator only needs to rotate the side impact protection case 11 from the folded state to the unfolded state. When the side impact protection case 11 is rotated, the positioning assembly 14 deforms and tends to drive the locking part 12 toward the fixing part 13 so that the locking end 121 is always pressed against the fixing part 13. When the side impact protection case 11 is switched to the unfolded state, the locking part 12 aligns with the locking recess 131 and is no longer blocked by the fixing part 13, and the positioning assembly 14 elastically recovers from deformation and pushes the locking end 121 into the locking recess 131. Since the locking part 12 is positioned in a predetermined position by the positioning assembly 14, the locking end 121 is always partially engaged with the locking recess 131, thereby holding the side impact protection case 11 in the unfolded state and cushioning the side impact force applied to the child seat 100.

[0039] As shown in Figure 6, when the child seat 100 is subjected to a lateral impact force in the direction indicated by arrow F2, the operating end 122 of the locking portion 12 protruding from the lateral impact protection case 11 is the first part to receive the lateral impact force. As a result, the locking portion 12 is pushed into the lateral impact protection case 11, and the locking end 121 extends completely into the locking recess 131, locking and holding the lateral impact protection case 11 in an unfolded state. The lateral impact protection case 11 plays a role in cushioning the lateral impact force that the vehicle body exerts on the child seat 100 during a lateral impact accident, thereby ensuring the safe use of the child seat 100.

[0040] As mentioned above, pressing the side impact protection case 11 means applying a pressing force to the side impact protection case 11 in order to rotate it; and the pressing force acts in a direction perpendicular to the longitudinal extension direction of the side impact protection case 11.

[0041] The side impact protection mechanism 10 of this disclosure includes a side impact protection case 11 and a locking portion 12, compared to currently available technical means. The side impact protection case 11 is held in an extended state by the locking portion 12 being locked to a side portion 21 of the child seat 100. The locking portion 12 includes a locking end 121 that is slidably installed within the side impact protection case 11 and is detachably engaged with the side portion 21. The locking end 121 is fully locked to the side portion 21 when the side impact protection case 11 is in an extended state and subjected to a side impact force. On the other hand, when the side impact protection case 11 is in an extended state but not subjected to a side impact force, the locking end 121 is partially locked to the side portion 21. In the latter case, when the side impact protection case 11 is pushed to rotate relative to the side portion 21, the locking end 121 releases partial locking from the side portion 21 by the rotation of the side impact protection case 11, ensuring that the side impact protection case 11 can be reliably switched from the deployed state to the folded state. The locking end 121 is fully locked to the side portion 21 when the side impact protection case 11 is deployed and subjected to a side impact force, so that the side impact protection case 11 can be stably held in the deployed state. This means that the side impact protection mechanism 10 can quickly provide a cushioning effect when a side impact occurs, ensuring safe use. On the other hand, when the side impact protection case 11 is deployed but not subjected to a side impact force, the locking end 121 is only partially locked to the side portion 21, so the locking end 121 can be completely released from partial locking to the side portion 21 by manually pushing the side impact protection case 11 to rotate, without needing to operate the locking release means. This effectively improves the folding speed of the side impact protection mechanism 10, making it easier and quicker to fold the side impact protection mechanism 10. Furthermore, since the side impact protection mechanism 10 of this disclosure does not include a locking release means that requires operator intervention, the side impact protection mechanism 10 can have an effectively optimized and simplified structure.

[0042] It can be understood that a child seat 100 equipped with the side impact protection mechanism 10 of this disclosure also has the same technical effect as the side impact protection mechanism 10.

[0043] Although this disclosure has been described using specific embodiments, those skilled in the art can make many modifications and variations without departing from the scope and spirit of this disclosure as set forth in the claims. [Explanation of symbols]
