Description

Technical Field

[0001] This invention relates to the field of child safety seat technology, and in particular to a control mechanism for a multi-functional seat adjustment mechanism and a child safety seat thereof. Background Technology

[0002] Child safety seats are seats specifically designed for children. With social development and improved living standards, their use in families is becoming increasingly common. The primary function of a child safety seat is to protect children during vehicle travel, preventing or reducing injuries caused by collisions or sudden braking. However, traditional child safety seats are typically bulky, making them inconvenient to carry and store, especially in smaller cars where storage space is limited. Furthermore, the use of traditional child safety seats is cumbersome, requiring repeated adjustments and securing, which increases both the difficulty of use and the time spent in their care.

[0003] Currently, some child safety seats also have rotation and angle adjustment functions. For example, patent application number 201710442015.7, entitled "Child Safety Seat," discloses a child safety seat, a support base that can be placed on a car seat, the support base including a fixed part and a support part connected to the fixed part; a rotating platform; and a child seat. The child seat, the rotating platform, and the support part can move synchronously relative to the fixed part, and the child seat and the rotating platform can rotate synchronously between multiple positions as a seat unit. However, in use, it requires separate control of the tilt adjustment lock and the seat rotation lock through a release mechanism and a release element. That is, it requires two different mechanisms to control the opening and closing of the tilt adjustment lock and the seat rotation lock, and thus control the angle adjustment and rotation of the seat respectively. The structure is complex, the cost is high, the precision requirements between the components are high, which increases the manufacturing cost in the production process, and the operation steps are very troublesome and inconvenient to use. In addition, due to the relatively small space inside the vehicle, it is very difficult for parents to secure their children to the car seat or take them out of the car seat. Existing car seats usually and rarely have the function of sliding while rotating, and they also require another release mechanism to control the sliding, which is complicated to operate and not easy to use.

[0004] Therefore, a control mechanism for a multi-functional seat adjustment system and a child safety seat are needed to solve this problem. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the purpose of this invention is to provide a control mechanism for a multi-functional seat adjustment mechanism and a child safety seat thereof, which effectively solves the problems of existing child safety seats not being able to conveniently adjust the tilt angle and horizontal angle of the installed seat and not being able to move the installed seat to the car door.

[0055] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0056] Example 1:

[0057] Depend on Figures 2 to 9Provided is a control mechanism for a seat angle adjustment mechanism and a direction adjustment mechanism, including a direction adjustment mechanism 4. The direction adjustment mechanism 4 includes a base 1 and a fixed frame 2 rotatably mounted on the base 1. The base 1 is provided with at least one hard locking point 41 and at least one soft locking point 42, preferably two hard locking points 41 and soft locking points 42. The lower end of the fixed frame 2 is provided with a telescopic first locking shaft 43, so that during the rotation of the fixed frame 2 on the base 1, the engagement of the hard locking point 41 or the soft locking point 42 with the first locking shaft 43 adjusts the fixed frame 2. The fixed frame 2 is equipped with a first locking element 44 to control the extension and retraction position of the first locking shaft 43 to cooperate with the engagement or disengagement of the first locking shaft 43 and the hard locking point 41. The hard limit requires the use of a release element that cooperates with the first locking element 44 to drive the first locking shaft 43 to separate from the hard locking point 41 so that the fixed frame 2 can rotate. The soft limit can be directly driven by applying a circumferential force to the fixed frame 2 to drive the first locking shaft 43 to separate from the soft locking point 42 so that the fixed frame 2 can rotate. The fixed frame 2 is also equipped with a seat 3.

[0058] Specifically, the base 1 is provided with a first annular groove 11 and a second annular groove 12 arranged concentrically. The fixing frame 2 is rotatably installed in the first annular groove 11. Hard locking point 41 and soft locking point 42 are arranged in the second annular groove 12. The hard locking point 41 is a dark groove whose shape fits the first locking shaft 43. The soft locking point 42 is an arc-shaped groove with an arc-shaped side around the perimeter.

[0059] It should be noted that the hard locking point 41 is located in the front-rear direction of the base 1, the soft locking point 42 is located on the side of the base 1, and the angle between the hard locking point 41 and the adjacent soft locking point 42 is 90°.

[0060] Specifically, the first locking element 44 includes a lock body 441 mounted on the fixed frame 2. The lock body 441 has a lock groove 442 perpendicular to the upper surface of the base 1. A first retaining pin 43 is slidably mounted within the lock groove 442. A first spring 443 is also provided within the lock groove 442. The two ends of the first spring 443 are respectively connected to the end face of the lock groove 442 and the first retaining pin 43, applying a force to the first retaining pin 43 to cause it to leave the groove and move towards the base 1. An interpretation control element 444 is also movably mounted on the lock body 441. 444 constitutes the unlocking component of the first locking component 44. The side of the release control component 444 is provided with an inclined slide groove 445. The first locking shaft 43 is also provided with a connecting shaft 446 that is slidably connected to the inclined slide groove 445. The locking component slide groove 442 is also provided with a through groove. The connecting shaft 446 passes through the through groove and the inclined slide groove 445. The movement of the release control component 444 can drive the connecting shaft 446 and the first locking shaft 43 to move through the inclined slide groove 445. This constitutes a structure in which the release control component 444, in conjunction with the first spring 443, can control the first locking shaft 43 to lock or unlock with the hard locking point 41 or the soft locking point 42.

[0061] The lock body 441 is provided with a sliding groove 447, and the release control member 444 is slidably installed in the sliding groove 447. A second spring 448 is also provided in the sliding groove 447. The two ends of the second spring 448 are respectively connected to the release control member 444 and the lock body 441. In conjunction with the first spring 443, the release control member 444 can stably enter the soft locking point 42 or the hard locking point 41 without being affected by other external forces.

[0062] The first annular groove 11 is provided with a plurality of limit buckles 13, and the periphery of the fixing frame 2 is provided with a retaining edge 14 that cooperates with the limit buckles 13. The cooperation between the retaining edge 14 and the limit buckles 13 enables the fixing frame 2 to rotate on the base 1 without detaching from the base 1.

[0063] There are two connecting shafts 446, which are located on both sides of the first locking shaft 43. The two connecting shafts 446 are respectively connected to the inclined sliding grooves 445 on both sides of the interpretation control component 444, so that the movement of the first locking shaft 43 is more stable.

[0064] To make it easier and less wear-prone for the first locking shaft 43 to enter the hard locking point 41 and the soft locking point 42, the lower end of the first locking shaft 43 is provided with a frustum-shaped chamfer.

[0065] A control mechanism for a seat angle adjustment mechanism and a direction adjustment mechanism further includes an angle adjustment mechanism 5. The angle adjustment mechanism 5 includes at least one arc-shaped bracket 51 mounted on a fixed frame 2. A seat 3 is movably mounted on the arc-shaped bracket 51. The arc-shaped bracket 51 is provided with a plurality of fixing holes 52 arranged at intervals along the movement direction of the seat 3 in the arc-shaped bracket 51. A second locking shaft 53 is movably provided on the seat 3, pointing in the direction of movement towards the arc-shaped bracket 51. A second locking member 54 is provided on the seat 3 to control the second locking shaft 53 to engage or disengage with any one of the fixing holes 52.

[0066] The seat 3 is provided with a control groove 55 perpendicular to the direction of the arc-shaped bracket 51. Two second locking shafts 53 are slidably disposed at both ends of the control groove 55. A third spring is also provided in the control groove 55, with both ends of the third spring connected to the two second locking shafts 53 respectively, applying a force to the second locking shafts 53 in the direction of the control groove 55. The second locking member 54 includes a fixed seat 541 disposed at the front end of the seat 3. A handle box 542 is movably installed in the fixed seat 541. The fixed seat 541 is provided with a communicating groove communicating with the inner cavity of the fixed seat 541. The handle box 542 is slidably installed in the communicating groove. Inside the cavity of the fixed base 541, the handle box 542 is provided with two connecting slides 543 that are inclined to the control slide 55. The two connecting slides 543 are inclined in opposite directions, and the end of the connecting slide 543 near the second locking shaft 53 is close to the fixing hole 52. Control pins 544 are slidably installed in the two connecting slides 543 respectively. The lower ends of the two control pins 544 are respectively hinged to the two second locking shafts 53. Pulling the handle box 542 drives the second locking shaft 53 to move in the control slide 55 through the control pins 544, thereby controlling the engagement and disengagement of the second locking shaft 53 with the fixing hole 52.

[0067] Specifically, the two ends of the arc-shaped bracket 51 are respectively provided with a front adjustment groove 56 and a rear adjustment groove 57, and the front and rear ends of the seat 3 are respectively provided with a front axle 561 and a rear axle 571 that are slidably disposed in the front adjustment groove 56 and the rear adjustment groove 57.

[0068] Specifically, the handle box 542 is provided with a linkage groove 545, and the front axle 561 is slidably installed in the linkage groove 545 so that the handle box 542 does not interfere with the position of the front axle 561. When the handle box 542 is pulled outward, the front axle 561 slides in the linkage groove 545, so that the handle box 542 first drives the second locking shaft 53 to separate from the fixing hole 52. At this time, the seat 3 can be pushed to adjust the angle of the seat 3. After adjusting to the appropriate position, the handle box 542 is controlled to return to the original position so that the second locking shaft 53 engages with the fixing hole 52 at the corresponding position, so that the position of the seat 3 and the fixing frame 2 is fixed.

[0069] Both the fixed base 541 and the handle box 542 are equipped with positioning shafts 546. The two positioning shafts 546 are connected by a tension spring 547. After the handle box 542 is pulled out and released, the handle box 542 returns to its original position under the action of the tension spring 547.

[0070] It is worth noting that the upper end of the control pin 544 is provided with a limiting block 548 to prevent the positioning pin from flipping in the connecting slide groove 543, thus ensuring the stability of the positioning pin sliding in the connecting slide groove 543.

[0071] It should be noted that the control component 444 is provided with a connector 71, which is connected to the handle box 542, thus forming a structure in which pulling the handle box 542 simultaneously controls the first lock component 44 and the second lock component 54.

[0072] Specifically, the connector 71 includes a pull rope 711. The control component 444 is provided with a first slot 712 and a first cable tray 713. The handle box 542 is provided with a second slot 714 and a second cable tray 715. The two ends of the pull rope 711 pass through the first cable tray 713 and the second cable tray 715 respectively and extend into the first slot 712 and the second slot 714. Both ends of the pull rope 711 are provided with a locking block 716. The two locking blocks 716 are rotatably locked into the first slot 712 and the second slot 714 respectively.

[0073] It should be noted that when the handle box 542 is pulled outward, the handle box 542 and the interpretation control component 444 move simultaneously in the pulling direction through the connection of the pull rope 711. This controls the first locking shaft 43 and the two second locking shafts 53 to leave the hard locking point 41 and the fixing hole 52 respectively. At this time, the seat 3 can be rotated and the tilt angle of the seat 3 can be adjusted. After the tilt angle and rotation angle of the seat 3 are adjusted, the handle box 542 and the interpretation control component 444 are reset under the action of the tension spring 547 and the second spring 448 respectively, so that the position of the seat 3 is fixed.

[0074] Example 2:

[0075] Depend on Figures 10 to 12 A control mechanism for a seat direction adjustment mechanism and a sliding mechanism is provided, comprising a base 1 and a fixed frame 2 rotatably mounted on the base 1. The base 1 is provided with at least one hard locking point 41 and at least one soft locking point 42, preferably two hard locking points 41 and soft locking points 42. The lower end of the fixed frame 2 is provided with a telescopic first locking shaft 43, so that during the rotation of the fixed frame 2 on the base 1, the engagement of the hard locking point 41 or the soft locking point 42 with the first locking shaft 43 provides hard and soft limiting for the fixed frame 2. The fixed frame 2 is provided with a first locking member 44 to control the telescopic position of the first locking shaft 43 to cooperate with the engagement or disengagement of the first locking shaft 43 with the hard locking point 41. Hard limiting requires the use of a release member that cooperates with the first locking member 44 to drive the first locking shaft 43 to separate from the hard locking point 41 so that the fixed frame 2 can rotate. Soft limiting can be directly achieved by applying a circumferential force to the fixed frame 2 to drive the first locking shaft 43 to separate from the soft locking point 42 so that the fixed frame 2 can rotate. A seat 3 is also mounted on the fixed frame 2.

[0076] It should be noted that the base 1 is provided with a first annular groove 11 and a second annular groove 12 arranged concentrically. The fixing frame 2 is rotatably installed in the first annular groove 11. The hard locking point 41 and the soft locking point 42 are arranged in the second annular groove 12. The hard locking point 41 is a dark groove whose shape fits the first locking shaft 43. The soft locking point 42 is an arc-shaped groove with an arc-shaped side. The angle between the hard locking point 41 and the adjacent soft locking point 42 is 90°.

[0077] The hard locking point 41 is located in the front-rear direction of the base 1, and the soft locking point 42 is located on the side of the base 1.

[0078] Specifically, the first locking element 44 includes a lock body 441 mounted on the fixed frame 2. The lock body 441 has a lock groove 442 perpendicular to the upper surface of the base 1. A first retaining pin 43 is slidably mounted within the lock groove 442. A first spring 443 is also provided within the lock groove 442. The two ends of the first spring 443 are respectively connected to the end face of the lock groove 442 and the first retaining pin 43, applying a force to the first retaining pin 43 to cause it to leave the groove and move towards the base 1. An interpretation control element 444 is also movably mounted on the lock body 441. 444 constitutes the unlocking component of the first locking component 44. The side of the release control component 444 is provided with an inclined slide groove 445. The first locking shaft 43 is also provided with a connecting shaft 446 that is slidably connected to the inclined slide groove 445. The locking component slide groove 442 is also provided with a through groove. The connecting shaft 446 passes through the through groove and the inclined slide groove 445. The movement of the release control component 444 can drive the connecting shaft 446 and the first locking shaft 43 to move through the inclined slide groove 445. This constitutes a structure in which the release control component 444, in conjunction with the first spring 443, can control the first locking shaft 43 to lock or unlock with the hard locking point 41 or the soft locking point 42.

[0079] The lock body 441 is provided with a sliding groove 447, and the release control member 444 is slidably installed in the sliding groove 447. A second spring 448 is also provided in the sliding groove 447. The two ends of the second spring 448 are respectively connected to the release control member 444 and the lock body 441. In conjunction with the first spring 443, the release control member 444 can stably enter the soft locking point 42 or the hard locking point 41 without being affected by other external forces.

[0080] The first annular groove 11 is provided with a plurality of limit buckles 13, and the periphery of the fixing frame 2 is provided with a retaining edge 14 that cooperates with the limit buckles 13. The cooperation between the retaining edge 14 and the limit buckles 13 enables the fixing frame 2 to rotate on the base 1 without detaching from the base 1.

[0081] There are two connecting shafts 446, which are located on both sides of the first locking shaft 43. The two connecting shafts 446 are respectively connected to the inclined sliding grooves 445 on both sides of the interpretation control component 444.

[0082] The lower end of the first bearing 43 is provided with a frustum-shaped chamfer.

[0083] A control mechanism for a seat direction adjustment mechanism and a sliding mechanism is provided, which further includes a sliding structure. The sliding mechanism 6 includes one or more sets of slide rails 61 arranged on the fixed frame 2 and in the same direction as the seating of the seat 3. The lower end of the seat 3 is slidably connected to the slide rails 61. The fixed frame 2 is also provided with a limiting mechanism so that when the seat 3 is rotated to a designated position, the seat 3 can slide on the fixed frame 2 through the slide rails 61.

[0084] The slide rail 61 has an inverted U-shaped structure. The lower end of the seat 3 is provided with multiple sets of rollers 62. The rollers 62 are rolled and installed in the slide rail 61. The upper and lower sides of the rollers 62 are rolled and connected to the inner bottom surface of the slide rail 61 and the upper end surface of the fixing frame 2, respectively, which limits the rollers in the vertical direction, improves the stability of the rollers 62 and prevents the rollers from sliding out of the slide rail 61.

[0085] The limiting mechanism includes a fixing ring 63 set on the upper end of the base 1. The fixing ring 63 has an opening 64 on the side perpendicular to the seating direction of the seat 3, so that the seat 3 can extend through the opening 64.

[0086] It should be noted that when the handle box 542 is pulled outward, the handle box 542 and the control component 444 move simultaneously in the pulling direction through the pull rope 711. This controls the first locking shaft 43 to leave the hard locking point 41. At this time, the seat 3 can be rotated. When the seat 3 is rotated to the side, the handle box 542 is reset under the action of the tension spring 547, fixing the position of the seat 3. The seat 3 and the fixing bracket 2 can be pulled out to the door through the opening 64, making it convenient to place the child on the seat. Since the first locking shaft 43 is located in the first annular groove 11, the first annular groove 11 can limit the first locking shaft 43 to prevent the seat 3 and the fixing bracket 2 from detaching from the base.

[0087] Example 3:

[0088] Depend on Figure 1-12 Provided, a child safety seat, including

[0089] Base 1, which is installed on the car seat 3;

[0090] Fixture 2 is rotatably mounted on base 1;

[0091] Seat 3 is movably mounted on the fixed frame 2;

[0092] The direction adjustment mechanism 4 enables the seat 3 to rotate synchronously between multiple positions, and the first locking element 44 on the direction adjustment mechanism 4 enables the seat 3 to be positioned in the corresponding position.

[0093] Angle adjustment mechanism 5 is used to adjust the angle between seat 3 and base 1. The second locking element 54 on angle adjustment mechanism 5 can position seat 3 at the corresponding angle.

[0094] The sliding mechanism 6 allows the seat 3 to slide on the base 1 when rotated to a specific position;

[0095] The control mechanism 7 can simultaneously control the opening and closing of the first lock 44 and the second lock 54 to adjust the horizontal rotation direction, the pitch angle and the position of the seat 3 through the seat 3 angle mechanism, the direction adjustment mechanism 4 and the sliding mechanism 6.

[0096] The direction adjustment mechanism 4 includes one or more hard locking points 41 and one or more soft locking points 42 disposed on the base 1. Preferably, there are two hard locking points 41 and soft locking points 42. The lower end of the fixing frame 2 is provided with a telescopic first locking shaft 43, so that the engagement of the hard locking point 41 or the soft locking point 42 with the first locking shaft 43 during the rotation of the fixing frame 2 on the base 1 can perform hard and soft limiting on the fixing frame 2. The fixing frame 2 is provided with a first locking member 44 to control the telescopic position of the first locking shaft 43 to cooperate with the engagement or separation of the first locking shaft 43 and the hard locking point 41. Hard limiting requires the use of a release member that cooperates with the first locking member 44 to drive the first locking shaft 43 to separate from the hard locking point 41 so that the fixing frame 2 can rotate. Soft limiting can be achieved by directly applying a circumferential force to the fixing frame 2 to drive the first locking shaft 43 to separate from the soft locking point 42 so that the fixing frame 2 can rotate.

[0097] The angle adjustment mechanism 5 includes at least one arc-shaped bracket 51 mounted on the fixed frame 2. The seat 3 is movably mounted on the arc-shaped bracket 51. The arc-shaped bracket 51 is provided with a plurality of fixing holes 52 arranged at intervals along the movement direction of the seat 3 in the arc-shaped bracket 51. The seat 3 is movably provided with a second locking shaft 53 pointing in the movement direction towards the arc-shaped bracket 51. The seat 3 is provided with a second locking member 54 to control the second locking shaft 53 to engage or disengage with any one of the fixing holes 52.

[0098] The sliding mechanism 6 includes one or more sets of slide rails 61 arranged on the fixed frame 2 and in the same direction as the seating 3. The lower end of the seating 3 is slidably connected to the slide rails 61. The fixed frame 2 is also provided with a limiting mechanism so that the seating 3 can slide on the fixed frame 2 via the slide rails 61 after rotating to the designated position.

[0099] The control mechanism 7 includes a connector 71 disposed on the control member 444. The connector 71 is connected to the handle box 542, forming a structure in which pulling the handle box 542 simultaneously controls the first lock member 44 and the second lock member 54.

[0100] The plastic parts included in this invention are manufactured using a blow molding process.

[0101] When using this invention, the base is installed on the car seat. When the handle box 542 is pulled outward, the handle box 542 and the control component 444 move simultaneously in the pulling direction through the pull rope 711. This controls the first locking shaft 43 and the two second locking shafts 53 to disengage from the hard locking point 41 and the fixing hole 52, respectively. At this time, the seat 3 can be rotated and the tilt angle of the seat 3 can be adjusted. After the tilt angle and rotation angle of the seat 3 are adjusted, the handle box 542 and the control component 444 are reset under the action of the tension spring 547 and the second spring 448, respectively, so that the position of the seat 3 is fixed. In addition, when the seat 3 is rotated to the side, the seat 3 and the fixing bracket 2 can be pulled out through the opening 64 to the car door, making it convenient to place a child on the seat. Then, the seat 3 and the fixing bracket 2 are pushed back to their original positions, and the handle box is pulled again to rotate the seat to the basic position.

[0102] The beneficial effects of this invention are:

[0103] (1) The angle adjustment mechanism can change the child's reclining angle in the safety seat, with a wide adjustment range and easy operation. It is fixed by two second pins, and the angle locking is highly reliable.

[0104] (2) The direction adjustment mechanism can change the direction of the child seat relative to the vehicle seat, making it easier for parents to put the child in and take the child safety seat out. Hard locking points are set in the direction where the child is normally sitting to hard limit the safety and improve the safety. Soft locking points are set in the side direction where it is convenient to put the child to improve the ease of use.

[0105] (3) The sliding mechanism can change the distance between the seat and the vehicle door, making it easier for parents to put their children in and take them out of the child safety seat.
