Description

Technical Field

[0001] This utility model relates to the field of children's products technology, specifically to a connecting component for a child safety seat and a child safety seat. Background Technology

[0002] Child safety seats are primarily used to protect children while they are traveling in a car. When a child safety seat is installed in a car seat, the inner tube of the connecting component usually extends a certain distance beyond the outer tube. In existing technology, when the inner tube extends a certain distance beyond the outer tube, the relative position between the outer and inner tubes is typically one-way locked. This allows the outer tube to be pushed backward, enabling the child safety seat to fit more closely against the car seat. However, because the relative position between the outer and inner tubes is not completely fixed, in the event of a rear-end collision, the outer tube can easily retract backward, causing the child safety seat to shake violently. This is especially true when the child safety seat is used rear-facing, as the child is more likely to collide with the car seat, potentially causing injury. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a connecting component for a child safety seat that can prevent the outer tube from retracting during a vehicle collision.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A connection component for a child safety seat includes: outer tube; The inner tube is slidably disposed within the outer tube in the front-to-back direction; A first locking mechanism is disposed between the outer tube and the inner tube to prevent the outer tube from sliding backward. The first locking mechanism has a first locking position and a second locking position when it is in the locked state. A second locking mechanism is provided between the outer tube and the inner tube to prevent the outer tube from sliding forward; When the child safety seat is not in use, the first locking mechanism is in the locked state and in the first locked position, and the second locking mechanism is in the locked state; when the child safety seat is in use, the first locking mechanism is in the unlocked state, and the second locking mechanism is in the locked state; when the child safety seat is in use and the car is involved in a rear-end collision, the first locking mechanism is in the locked state and in the second locked position.

[0005] In some embodiments, the first locking mechanism includes a first locking member movably disposed in the inner tube, the first locking member being provided with a first locking portion and a second locking portion, and the outer tube being provided with a first mating portion adapted to the first locking portion and a second mating portion adapted to the second locking portion; when the first locking mechanism is in a first locked position, the first locking portion is inserted into the first mating portion; when the first locking mechanism is in a second locked position, the second locking portion is inserted into the second mating portion; when the first locking mechanism is in an unlocked state, the first locking portion disengages from the first mating portion, and the second locking portion disengages from the second mating portion.

[0006] In some embodiments, the first locking member is rotatably disposed in the inner tube about a pivot, and the first locking mechanism is switched from an unlocked state to a locked position by rotating the first locking member about the pivot.

[0007] In some embodiments, the connection assembly further includes a first elastic element that drives the first locking mechanism to unlock when the first locking mechanism is locked in a second locking position, the first elastic element being disposed between the first locking element and the inner tube.

[0008] In some embodiments, the first locking member can also be slidably disposed in the inner tube, and the first locking mechanism can be switched from being locked in the first locked position to being unlocked by sliding the first locking member up and down.

[0009] In some embodiments, the connecting assembly further includes a sliding component for driving the first locking member from a locked position to an unlocked state, the sliding component being slidably disposed in the inner tube in a front-back direction.

[0010] In some embodiments, the sliding component is provided with a first guide groove, the first guide groove including a positioning part located in the middle and guide parts respectively provided on the front and rear sides of the positioning part, the guide parts on both sides extending forward or backward and downward from the positioning part respectively, the inner tube is provided with a second guide groove extending in the vertical direction, and the rotating shaft passes through both the first guide groove and the second guide groove; when the first locking mechanism is locked in the first locking position, the rotating shaft is located in the upper part of the positioning part and the second guide groove; when the first locking mechanism is in the unlocked state and locked in the second locking position, the rotating shaft is located in the lower part of the guide part and the lower part of the second guide groove.

[0011] In some embodiments, the second locking mechanism includes a second locking member rotatably disposed in the inner tube, the second locking member having a third locking portion, and the outer tube having a third mating portion adapted to the third locking portion. When the second locking mechanism is in a locked state, the third locking portion is inserted into the third mating portion; when the second locking mechanism is in an unlocked state, the third locking portion is disengaged from the third mating portion.

Moreover, the first locking mechanism has a first locking position and a second locking position when locked. Thus, when the child safety seat is in different states, the relative position between the outer tube and the inner tube can be locked by a first locking mechanism in conjunction with the second locking mechanism, making the structure of the connecting assembly simple and reducing the manufacturing cost of the connecting assembly.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] In the following description, the directions "front," "back," "left," "right," "up," and "down" all refer to... Figure 1 In the figure, the right direction is "front", the left direction is "rear", the upper direction is "up", and the lower direction is "down". The directions perpendicular to the paper are "left" and "right". The above definitions of directions are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0020] like Figures 1-4 As shown, the connecting assembly of the child safety seat of this utility model includes an outer tube 1, an inner tube 2, a first locking mechanism, and a second locking mechanism.

[0021] Both the outer tube 1 and the inner tube 2 extend in the front-to-back direction, and the inner tube 2 can be slidably disposed in the outer tube 1 in the front-to-back direction.

[0022] Both the first locking mechanism and the second locking mechanism are disposed between the outer tube 1 and the inner tube 2, and both are used to lock the relative position between the outer tube 1 and the inner tube 2. In this embodiment, both the first locking mechanism and the second locking mechanism are one-way locking mechanisms. When locked, the first locking mechanism prevents the outer tube 1 from sliding backward relative to the inner tube 2, and the second locking mechanism prevents the outer tube 1 from sliding forward relative to the inner tube 2.

[0023] The first locking mechanism has a first locking position and a second locking position when in the locked state. When the child safety seat is not in use, the first locking mechanism is in the locked state and in the first locking position, and the second locking mechanism is in the locked state, such as... Figure 1 As shown. When the child safety seat is in use, the first locking mechanism is in the unlocked state, and the second locking mechanism is in the locked state, as shown. Figure 3 As shown. When a rear-end collision occurs while the child safety seat is in use, the first locking mechanism is in the locked state and in the second locking position, while the second locking mechanism is in the locked state, as shown. Figure 4 As shown. During the installation of the child safety seat, when it is necessary to adjust the length of the inner tube 2 extending beyond the outer tube 1 by sliding relative to the outer tube 1, both the first locking mechanism and the second locking mechanism are in the unlocked state, as shown. Figure 2 As shown.

[0024] Specifically, such as Figures 1-4 and Figure 6 As shown, the first locking mechanism includes a first locking member 31 movably disposed in the inner tube, the first locking member 31 being provided with a first locking part 311 and a second locking part 312, and the outer tube 1 being provided with a first mating part 11 adapted to the first locking part 311 and a second mating part 12 adapted to the second locking part 312.

[0025] When the first locking mechanism is locked in the first locking position, the first locking part 311 is inserted into the first mating part 11, and at this time the second locking part 312 disengages from the second mating part 12, as follows: Figure 1 As shown. When the first locking mechanism is locked in the second locking position, the second locking part 312 is inserted into the second mating part 12, and at this time the first locking part 311 is disengaged from the first mating part 11, as shown. Figure 4 As shown. When the first locking mechanism is in the unlocked state, the first locking part 311 disengages from the first mating part 11, and the second locking part 312 disengages from the second mating part 12, as shown. Figure 2 and Figure 3 As shown.

[0026] The first locking member 31 is rotatably disposed in the inner tube 2 around the pivot 32. When the first locking mechanism is in the unlocked state, rotating the first locking member 31 around the pivot 32 can switch the first locking mechanism from the unlocked state to the locked second locking position. When the child safety seat is in use and a rear-end collision occurs, the impact force generated by the collision acts on the connecting assembly and is transmitted to the first locking member 31. Under the action of the impact force, the first locking member 31 rotates around the pivot 32, thereby locking the first locking mechanism in the second locking position.

[0027] The connecting assembly also includes a first elastic element 33. When the impact force from the collision disappears, the first locking element 31 rotates in the opposite direction around the pivot 32 under the elastic force of the first elastic element 33, thereby unlocking the first locking mechanism from the second locked position. The first elastic element 33 is disposed between the first locking element 31 and the inner tube 2; specifically, one end is disposed on the first locking element 31, and the other end is disposed on the inner tube 2. When the child safety seat is in use, the elastic force of the first elastic element 33 keeps the first locking mechanism in the unlocked state.

[0028] The first locking member 31 can also be slidably disposed in the inner tube 2. By making the first locking member 31 slide up and down relative to the inner tube 2, the first locking mechanism can be changed from the locked position to the unlocked state.

[0029] The connecting assembly also includes a sliding component 4, which drives the first locking member 31 from the locked first locking position to the unlocked state. The sliding component 4 is slidably disposed in the inner tube 2 in the front-back direction.

[0030] Specifically, such as Figure 6 As shown, the sliding component 4 is provided with a first guide groove. The first guide groove includes a positioning part 41 located in the middle and guide parts respectively provided on the front and rear sides of the positioning part 41. The guide part located on the front side of the positioning part 41 is defined as the first guide part 42, and the guide part located on the rear side of the positioning part 41 is defined as the second guide part 43. The first guide part 42 extends forward and downward from the intersection with the positioning part 41, and the second guide part 43 extends backward and downward from the intersection with the positioning part 41. The inner tube 2 is provided with a second guide groove 21 extending in the vertical direction. The rotating shaft 32 passes through both the first guide groove and the second guide groove 21. Figure 5 and Figure 6 As shown.

[0031] When the first locking mechanism is locked in the first locking position, the rotating shaft 32 is located above the positioning part 41 and the second guide groove 21, such as Figure 1 As shown.

[0032] When the first locking mechanism is locked in the first locked position, it drives the sliding component 4 to slide forward. The rotating shaft 32 gradually slides from the positioning part 41 into the second guide part 43 within the first guide groove. The inclined surface of the second guide part 43 acts on the rotating shaft 32, causing it to slide downwards from the upper end of the second guide groove 21. As the rotating shaft 32 slides downwards, it drives the first locking member 31 to slide downwards simultaneously, thereby gradually disengaging the first locking part 311 from the first mating part 11. When the first locking mechanism is in the unlocked state, the rotating shaft is located at the lower part of the second guide part 43 and the lower part of the second guide groove 21, as shown below. Figure 2 As shown.

[0033] When the first locking mechanism is locked in the first locked position, it drives the sliding component 4 to slide backward. The rotating shaft 32 gradually slides from the positioning part 41 into the first guide part 42 within the first guide groove. The inclined surface of the first guide part 42 acts on the rotating shaft 32, causing it to slide downward from the upper end of the second guide groove 21 along the second guide groove 21. As the rotating shaft 32 slides downward, it drives the first locking member 31 to slide downward simultaneously, thereby causing the first locking part 311 to gradually disengage from the first mating part 11. When the first locking mechanism is in the unlocked state, the rotating shaft is located at the lower part of the first guide part 42 and the lower part of the second guide groove 21, as shown below. Figure 3 As shown.

[0034] An operating lever 44 is fixedly installed on the sliding component 4. The operating lever 44 passes through the inner tube 2 and the outer tube 1 in sequence and extends to the outside of the outer tube 1 so that a person can hold the operating lever 44 to push the sliding component 4 to slide relative to the inner tube 2.

[0035] The second locking mechanism includes a second locking member 51 rotatably disposed in the inner tube 2, a third locking part 511 disposed on the second locking member, and a third mating part adapted to the third locking part 511 disposed on the outer tube 1. When the second locking mechanism is in the locked state, the third locking part 511 is inserted into the third mating part, such as... Figure 1 , Figure 3 and Figure 4 As shown. When the second locking mechanism is in the unlocked state, the third locking part 511 disengages from the third mating part, as... Figure 2 As shown.

[0036] The first locking part 311 and the second locking part 312 are respectively disposed at opposite ends of the first locking member 31. The first mating part 11 and the second mating part 12 are respectively disposed on opposite sides of the outer tube 1. The third mating part and the first mating part 11 are disposed on the same side of the outer tube 1. The third mating part may be the same as or different from the first mating part 11. Figure 7 and Figure 8 As shown.

[0037] In this embodiment, the first mating part 11 and the third mating part are both disposed at the top of the outer tube 1, and the second mating part 12 is disposed at the bottom of the outer tube 1. The first mating part 11 and the third mating part are the same, both being openings disposed on the outer tube 1, and multiple openings are provided at intervals along the length extension direction of the outer tube 1.

[0038] The sliding component 4 is provided with a first abutting part 45. When the second locking mechanism is in the locked state and the sliding component 4 slides towards the second locking member 51, the first abutting part 45 abuts against the second locking member 51, so that when the sliding component 4 continues to slide in the current direction, the second locking member 51 rotates relative to the inner tube 2, thereby unlocking the second locking mechanism.

[0039] The connecting assembly also includes a second elastic element 52. When the sliding assembly 4 slides away from the second locking element 51, after the first abutting part 45 disengages from the abutting engagement with the second locking element 51, the second locking element 51 rotates in the opposite direction under the elastic force of the second elastic element 52, thereby locking the second locking mechanism again.

[0040] The connection assembly also includes a third locking mechanism for connecting and locking to the anchoring part on the car seat.

[0041] The third locking mechanism includes a third locking member 6 rotatably disposed at the rear of the inner tube 2, and a fourth locking part 61 disposed on the third locking member, the fourth locking part 61 being detachably engaged with the anchoring part on the car seat.

[0042] The connecting assembly also includes a third elastic member 7, one end of which is disposed on the third locking member 6, and the other end of which is disposed on the sliding assembly 4.

[0043] The sliding assembly 4 is provided with a second abutment 46. When the third locking mechanism is in the locked state, under the elastic force of the third elastic member 7, the second abutment 46 abuts against the third locking member 6, preventing the third locking member 6 from rotating relative to the inner tube 2, thus keeping the third locking mechanism locked. When the sliding assembly 4 slides forward, the second abutment 46 moves away from the third locking member 6, allowing the third locking member 6 to rotate relative to the inner tube 2 under the pull of the third elastic member 7, thereby unlocking the third locking mechanism.

[0044] The child safety seat in this embodiment includes a seat body and a connecting component disposed on the seat body. The connecting component adopts the above-described structural form, and the outer tube 1 of the connecting component is fixedly disposed on the seat body. The child safety seat is connected to the car seat through the connecting component.

[0045] When the child safety seat is not in use, the inner tube 2 is mostly retracted into the outer tube 1. The combined action of the first and second locking mechanisms locks the relative positions of the outer tube 1 and inner tube 2, preventing them from sliding against each other and thus avoiding damage to the connecting components. At this time, the first locking mechanism is locked in the first locked position, and the third locking mechanism is in the unlocked state. Figure 1 As shown.

[0046] When a child safety seat needs to be installed in a car seat, to facilitate installation, the inner tube 2 needs to extend a certain length beyond the outer tube 1. By unlocking both the first and second locking mechanisms, the inner tube 2 and the outer tube 1 can slide freely relative to each other in both directions, thereby adjusting the length of the extended inner tube 2. Figure 2 As shown. The operation to unlock the first and second locking mechanisms is as follows: A person holds the operating lever 44 and pushes the sliding assembly 4 forward relative to the inner tube 2. The rotating shaft 32 enters the second guide portion 43. Under the combined action of the second guide portion 43 and the second guide groove 21, the first locking member 31 slides downward relative to the inner tube 2, thereby disengaging the first locking part 311 from the first mating part 11, thus unlocking the first locking mechanism. When the sliding assembly 4 slides forward, the first abutting part 45 abuts against the second locking member 51, causing the second locking member 51 to rotate relative to the inner tube 2, thus disengaging the second locking part 511 from the third mating part, thereby unlocking the second locking mechanism.

[0047] When the child safety seat is installed in the car seat and needs to be locked in place by the third locking mechanism, the anchoring part on the car seat is engaged in the fourth locking part 61. During the process of the third locking member 6 rotating to lock the third locking mechanism, the third elastic member 7 pulls the sliding assembly 4 backward. Under the combined action of the second guide part 43 and the second guide groove 21, the first locking member 31 slides upward relative to the inner tube 2 until the first locking mechanism is in the first locked position. As the sliding assembly 4 continues to slide backward under the action of the third locking member 6, the rotating shaft 32 enters the first guide part 42. Under the combined action of the first guide part 42 and the second guide groove 21, the first locking member 31 slides downward relative to the inner tube 2 until the third locking mechanism is locked, and then the first locking mechanism unlocks again. At this time, the sliding assembly 4 slides to the second abutment part 46 abutting against the third locking member 6, and the first abutment part 45 moves away from the second locking member 51. The second locking member 51 then rotates under the elastic force of the second elastic member 52, locking the second locking mechanism again, and the child safety seat is now in use. At this time, the outer tube 1 can only slide backward and retract relative to the inner tube 2, such as Figure 3 As shown.

[0048] When a car is rear-ended while the child safety seat is in use, the first locking member 31 rotates around the pivot 32 under the impact force generated by the collision, thereby locking the first locking mechanism. Since both the first and second locking mechanisms are in the locked state, the outer tube 1 and the inner tube 2 cannot slide relative to each other, and the outer tube 1 cannot retract, thus preventing the child safety seat from sliding backward and improving the safety performance of the child safety seat during use.

[0049] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
