As shown in fig. 1 to 8, in one aspect of the present disclosure, there is provided a headrest adjusting mechanism of a child safety seat, including: seat body 1, rack 11, headrest subassembly 2, profile locking subassembly 3 and release subassembly.
Wherein the seat body 1 has a backrest and a seat plate; the rack 11 is arranged in the backrest and exposed out of the front side of the backrest; the headrest assembly 2 comprises a pillow part 21 and an insertion part 22 positioned below the pillow part 21, wherein the insertion part 22 is slidably arranged on the front side of the backrest, and a first accommodating groove 23 is formed in one side close to the backrest; the tooth-shaped locking member 3 is slidably disposed in the first receiving groove 23 and configured to engage with the rack 11 in a state where the insertion portion 22 and the backrest are assembled with each other, to lock the headrest member 2; and the unlocking assembly is slidably disposed on the headrest assembly 2 and connected with the tooth-shaped locking assembly 3, and is configured to disengage the tooth-shaped locking assembly 3 from the meshing position with the rack 11 when actuated, so that the headrest assembly 2 is height-adjustable relative to the seat body 1.
As shown in fig. 2 to 3, the headrest assembly 2 can be adjusted in height relative to the backrest of the seat body 1 along the rack 11 by the guiding action of the rack 11. The adjustable height of the entire headrest assembly 2 is 200mm, and considering that the pitch of the teeth of the rack 11 is 1mm, the headrest assembly 2 can be finely adjusted by 200 steps in theory, thereby approaching the effect of achieving stepless adjustment of the height of the headrest assembly 2 with respect to the backrest of the seat body 1.
As shown in fig. 4, in order to define the headrest assembly 2 at a set height of the rack gear 11, the present disclosure engages with the rack gear 11 through the tooth lock assembly 3, thereby defining the position of the headrest assembly 2 with respect to the rack gear 11. In order to adjust the height of the headrest assembly 2 relative to the seat body 1, the tooth-shaped lock assembly 3 is further unlocked from the rack bar 11 by the unlocking assembly, so that the headrest assembly 2 can move up and down relative to the rack bar 11 during height adjustment.
In order to ensure that the meshing relationship between the tooth lock assembly 3 and the rack bar 11 can limit the height of the headrest assembly 2 relative to the seat body 1, in some embodiments, the length direction of the rack bar 11 is parallel to the sliding direction of the headrest assembly 2, and the sliding direction of the tooth lock assembly 3 is perpendicular to the sliding direction of the headrest assembly 2.
That is, in some embodiments, the tooth height direction of the rack 11 is set along the width direction of the backrest, an avoiding notch 12 is further opened on one side of the tooth top of the rack 11 away from the tooth bottom, and the avoiding notch 12 can provide the tooth-shaped locking component 3 with a receiving space, so that the tooth-shaped locking component 3 is disengaged from the rack 11 when being located inside the avoiding notch 12.
As shown in fig. 6-7, similarly, in some embodiments, to facilitate operation of the unlocking assembly, the sliding direction of the unlocking assembly is parallel to the sliding direction of the headrest assembly 2. At this time, the unlocking assembly includes the first spring 41 and the pulling plate 5.
The first spring 41 is arranged on one side of the tooth-shaped locking component 3 away from the rack 11 and pushes the tooth-shaped locking component 3 to be meshed with the rack 11 under the normal state; and the pulling plate 5 is arranged on the back of the headrest assembly 2 and is configured to overcome the elastic force of the first spring 41 and drive the tooth-shaped locking assembly 3 to move to the side away from the rack 11 when moving upward relative to the headrest assembly 2.
Since the sliding direction of the pulling plate 5 is perpendicular to the direction in which the tooth-shaped locking component 3 is engaged with the rack 11, the unlocking process of the unlocking component pair needs to switch between two angles perpendicular to each other, and in some embodiments, the tooth-shaped locking component 3 includes a first driving rod 31, and the first driving rod 31 extends backward along the insertion portion 22 in a state in which the tooth-shaped locking component 3 is disposed in the first receiving groove 23.
The pulling plate 5 is provided with a first driving slanting groove 51 accommodating the first driving lever 31, a first end of the first driving slanting groove 51 is located at an upper side of the second end and near a center line of the headrest assembly 2, and the first driving lever 31 is located at the first end of the first driving slanting groove 51 when the tooth-shaped locking assembly 3 is engaged with the rack 11. Thus, when the pulling plate 5 moves upward, the first driving rod 31 is forcibly moved from the first end to the second end of the first driving chute 51, and brings the toothed locking assembly 3 out of engagement with the rack 11.
In order to ensure that the unlocking assembly completely disengages the toothed locking assembly 3 from the toothed rack 11, the distance between the first end and the second end of the first driving chute 51 in the width direction is not less than the movement distance of the toothed locking assembly 3 with respect to the toothed rack 11; in order to quickly and smoothly re-engage the tooth-shaped locking assembly 3 with the rack 11 after the headrest height is adjusted, when the first driving inclined groove 51 disengages the tooth-shaped locking assembly 3 from the rack 11, the gap between the tooth-shaped locking assembly 3 and the rack 11 should be controlled to be as small as possible, for example, the gap is controlled to be 0.5 to 1.5 mm. Thus, after the pulling plate 5 is pulled up to disengage the tooth-shaped lock assembly 3 from the rack 11, the headrest assembly 2 is pulled up to release the pulling plate 5 at an arbitrary position, and the headrest assembly 2 can be positioned on the rack 11 at the position.
As shown in fig. 5, in order to balance the left and right forces of the pulling plate 5, in some embodiments, the headrest adjusting mechanism further comprises a balancing component for balancing the single-side force applied to the pulling plate 5 by the tooth-shaped locking component 3 during the movement of the pulling plate 5, so that the resultant force direction of the balancing component is parallel to the length direction of the rack 11.
Specifically, the headrest assembly 2 is further provided with a second accommodating groove 24, the pull plate 5 is further provided with a second driving inclined groove 52, the second accommodating groove 24 and the first accommodating groove 23 are symmetrically distributed by taking the center line of the headrest assembly 2 as a symmetry axis, and the second driving inclined groove 52 and the first driving inclined groove 51 are symmetrically distributed;
the counterbalance assembly further includes a counterbalance 6 and a second spring 42. The balance member 6 is similar to the tooth-shaped locking assembly 3 in shape and structure, is slidably disposed in the second receiving groove 24 along the width direction of the backrest, and includes a second driving rod 61, and the second driving rod 61 is disposed in the second driving inclined groove 52; the second spring 42, which has the same specification as the first spring 41, is disposed on a side of the balance member 6 away from the rack 11.
Therefore, as shown in fig. 8, the first driving oblique slot 51 and the second driving oblique slot 52 constitute two oblique slots symmetrically distributed in a shape like a Chinese character 'ba', and at this time, in the process of pulling up the pulling plate 5, the balance piece 6 and the tooth-shaped locking assembly 3 apply acting forces perpendicular to the respective driving oblique slots and toward the outside of the seat body 1 to the pulling plate 5 under the action of the respective corresponding first spring 41 and second spring 42, and the horizontal component forces of the two obliquely outward acting forces are in opposite directions, so that the overall resultant force direction received by the pulling plate 5 is parallel to the sliding direction of the pulling plate, and the forces applied to the pulling plate 5 in the sliding process are balanced.
Further, in order to enable the relative movement between the backrest and the pull plate 5 of the headrest assembly 2 along a set track, in some embodiments, the backrest is provided with the boss guide shaft 13, the headrest and the pull plate 5 are correspondingly provided with the guide groove 25 for the boss guide shaft 13 to slide, and the length direction of the guide groove 25 is arranged along the height direction of the backrest.
In another aspect of the present disclosure, there is provided a child safety seat comprising a headrest adjustment mechanism of the child safety seat according to any of the preceding embodiments.
Therefore, according to the embodiment of the present disclosure, based on the mutual cooperation of the tooth-shaped locking component 3 and the unlocking component, the headrest height can be flexibly adjusted at any position, and the headrest can be ensured to be fixed at a new height position after the adjustment is stopped, so that the headrest component 2 of the child safety seat can be adaptively adjusted according to the physical condition of a child passenger, and the comfort and the safety of the child safety seat are improved.
Thus, various embodiments of the present disclosure have been described in detail.
