Description

[Technical Field]

[0001] This invention relates to the field of child passenger vehicle safety products, specifically to a child safety seat. [Background Technology]

[0002] An existing child safety seat adjustment structure, with publication number CN107499202A, includes a seat body and a base. A tilt adjustment mechanism is provided between the seat body and the base. The base includes a base body with a guide rail on its inner side. The guide rail has several positioning grooves. The tilt adjustment mechanism includes the guide rail, a connecting seat, and a movable seat. The connecting seat is fixed to the bottom of the seat body, and the movable seat is movably positioned at the bottom of the seat body. The movable seat and the connecting seat are connected by a positioning rod. Pulling the movable seat forward and backward allows the positioning rod to move up and down on the connecting seat. The two sides of the positioning rod engage with the positioning grooves, and the positioning rod can disengage from the positioning grooves when it moves upward. The seat body includes a seat cushion and a backrest. The movable seat drives the positioning rod to move up and down. When the positioning rod disengages from the positioning groove, the seat cushion can move relative to the base. Since the seat cushion and the guide rail have an arc surface engagement, the seat tilt angle is adjusted as the seat cushion moves along the arc surface of the guide rail.

[0003] The existing ISOFIX mounting structure for a reversible child safety seat, with announcement number CN106965717A, includes a child safety seat, a base, and ISOFIX components. The child safety seat is fixedly mounted on top of the base. There are two ISOFIX components, which are respectively mounted on the left and right sides below the base. Each ISOFIX component includes an ISOFIX frame, a vertically arranged rotating shaft at the rear end of the ISOFIX frame, and limiting brackets on the left and right sides of the middle of the ISOFIX frame. The ISOFIX component is mounted in the middle of the base via the rotating shaft. Each ISOFIX component is equipped with two elastic locking mechanisms, which are symmetrically arranged at a distance from each other on the bottom of the base. When the ISOFIX component is rotated horizontally outward around the rotating shaft to the front or rear position, the ISOFIX component locks itself by cooperating with one of the limiting brackets and one of the elastic locking mechanisms. When the ISOFIX assembly is rotated horizontally outward around the rotation axis to the forward position, the ISOFIX assembly is locked by one of the limit brackets and one of the elastic locking mechanisms. When the ISOFIX assembly is rotated horizontally outward around the rotation axis to the reverse position, the ISOFIX assembly is locked by another limit bracket and another elastic locking mechanism.

[0004] These two patents respectively realize the position adjustment of the seat and base of the child safety seat and the reversing adjustment between the seat and base. However, the structure of these two adjustments is separate. They can only be adjusted by unlocking them in different positions. Therefore, it is very troublesome for adults to operate when they need to perform reversing operation and position adjustment at the same time. Moreover, the small space in the back seat of the car is not convenient for adults to operate, making the whole operation cumbersome and inconvenient.

[0005] This invention was developed based on the aforementioned shortcomings. [Summary of the Invention]

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a child safety seat that can adjust gears and rotate in one button.

[0007] This invention is achieved through the following technical solution:

[0008] A child safety seat includes a base 1, on which a seat body 2 is connected. A gear adjustment mechanism 3 is provided between the seat body 2 and the base 1 to adjust the angle between them. A reversing mechanism 4 is also provided between the seat body 2 and the base 1. When the seat body 2 is adjusted to the maximum angle position relative to the base 1, the gear adjustment mechanism 3 can be activated to allow the seat body 2 to rotate and reverse relative to the base 1.

[0009] The gear adjustment mechanism 3 allows the tilt angle between the seat body 2 and the base 1 to be between 0 and 14°.

[0010] The gear adjustment mechanism 3 enables the seat body 2 to be adjusted relative to the base 1 to include the original angle gear, the first angle gear, the second angle gear, and the maximum angle gear.

[0011] The reversing mechanism 4 enables the seat body 2 to rotate within a range of 0-360° relative to the base 1. The reversing mechanism 4 enables the seat body 2 to adjust to the base 1 in the following reversing positions: the original reversing position, the first reversing position, the second reversing position, and the third reversing position.

[0012] The gear adjustment mechanism 3 includes gear adjustment holes 31 located on the reversing mechanism 4 and corresponding to each angle gear position. The seat body 2 is connected to an unlocking handle 32 that can slide back and forth relative to it. The seat body 2 is provided with a locking member 33 that can slide relative to it and engage or disengage from the gear adjustment hole 31. The locking member 33 and the seat body 2 are provided with a first elastic member 34 that can reset the locking member 33. The unlocking handle 32 and the seat body 2 are provided with a second elastic member 35 that can reset the unlocking handle 32. The gear adjustment hole 31 includes a first gear adjustment hole 311, a second gear adjustment hole 312, a third gear adjustment hole 313, and a fourth gear adjustment hole 314 that correspond to the original angle gear position, the first angle gear position, the second angle gear position, and the maximum angle gear position, respectively.

[0013] The latching member 33 includes a latching pin 331 slidably connected to the seat body 2. The latching pin 331 has a protrusion 332 that extends upward and latches into the unlocking handle 32. The unlocking handle 32 includes a handle body 321 and an extension 322 that is connected to the handle body 321 and extends backward. The extension 322 has a groove 3221 for the latching pin 331 to slide inside. The extension 322 has a pressing oblique groove 3222 that allows the protrusion 332 to slide inside and presses against the protrusion 332 when the unlocking handle 32 slides, causing the latching pin 331 to disengage from the gear adjustment hole 31.

[0014] The reversing mechanism 4 includes a turntable 41 rotatably connected to the base 1. The base 1 is provided with a plurality of reversing positioning holes 42 that correspond to each reversing gear position. The turntable 41 is provided with a locking member 43 that can slide laterally relative to it and engage or disengage from the reversing positioning holes 42. The unlocking handle 32 is provided with a mechanism that can abut against the locking member 43 when the seat body 2 is in the original angle position, the first angle position, the second angle position, and the maximum angle position, so that the locking member 43 is held in place. The top surface 44 is locked in the reversing positioning hole 42. A third elastic element 45 is provided between the locking member 43 and the turntable 41, which can push the locking member 43 to slide relative to the locking member 43 so that the locking member 43 disengages from the reversing positioning hole 42. The unlocking handle 32 is provided with a clearance groove 46 that can make way for the locking member 43 when the seat body 2 is adjusted to the maximum angle position relative to the base 1 and the unlocking handle 32 is pulled to slide, so that the locking member 43 disengages from the reversing positioning hole 42.

[0015] The locking member 43 includes a first pin 431 that can slide laterally relative to the turntable 41, a second pin 432 that is vertically arranged on the first pin 431, and the two ends of the third elastic member 45 abut against the second pin 432 and the wall of the turntable 41, respectively.

[0016] The base 1 is provided with a connecting seat 11 that protrudes upward and extends into the turntable 41. Multiple reversing positioning holes 42 are provided on the connecting seat 11. The turntable 41 is provided with a slot 411 for the connecting seat 11 to be inserted.

[0017] The turntable 41 includes a rotating seat 412 connected to the base 1 and a connecting piece 413 connected to the base 1. The seat body 2 is provided with a first crossbar 5 through which the connecting piece 413 passes laterally. The connecting piece 413 is provided with a first limiting groove 4131 in which the first crossbar 5 can slide. A second crossbar 6 is provided laterally between the seat body 2, the connecting piece 413 and the unlocking handle 32. The connecting piece 413 is provided with a second limiting groove 4132 in which the second crossbar 6 can slide. The unlocking handle 32 is also provided with a third limiting groove 323 in which the second crossbar 6 can slide. The third limiting groove 323 is provided with a pushing surface 3231 that can push the second crossbar 6 to slide in the second limiting groove 4132 when the unlocking handle 32 is pulled.

[0018] Compared with the prior art, the present invention has the following advantages: When the child safety seat of the present invention is installed on the car seat, when it is necessary to change the direction of the child safety seat, the seat body is first adjusted to the maximum angle position relative to the base by the gear adjustment mechanism. Then, the gear adjustment mechanism is operated to move. When the gear adjustment mechanism is in place, the reversing mechanism is unlocked. At this time, the seat body can rotate relative to the base to change direction. The entire reversing operation does not require removing the seat body from the base. It only requires operating the gear adjustment mechanism to unlock. The operation is very convenient. Moreover, when the gear adjustment mechanism is adjusted back from the maximum angle position, it can lock the seat body and the base again. At this time, the seat body cannot rotate relative to the base to change direction, which plays a secondary locking role, making it safer. Furthermore, when the reversing mechanism rotates the seat body 180 degrees from the original reversing position, the seat body rotates from facing forward to facing backward, which is the safest and most comfortable use angle in the field of safety seats. There is no need to make further reversing adjustments to meet the usage requirements. [Attached Image Description]

[0044] The present invention will now be further described with reference to the accompanying drawings:

[0045] like Figures 1 to 25 As shown, the present invention provides a child safety seat, including a base 1, on which a seat body 2 is connected. A gear adjustment mechanism 3 is provided between the seat body 2 and the base 1, which can adjust the angle between the two. A reversing mechanism 4 is also provided between the seat body 2 and the base 1. When the seat body 2 is adjusted to the maximum angle position relative to the base 1, the gear adjustment mechanism 3 can be activated to allow the seat body 2 to rotate and reverse relative to the base 1.

[0046] This invention relates to a child safety seat that is installed in a car seat. When the child safety seat needs to be repositioned, the seat body 2 is first adjusted to the maximum angle relative to the base 1 using the gear adjustment mechanism 3. Then, the gear adjustment mechanism 3 is operated continuously. When the gear adjustment mechanism 3 is in place, the reversing mechanism 4 is unlocked, and the seat body 2 can then rotate relative to the base 1. The entire reversing operation does not require removing the seat body 2 from the base 1; only the gear adjustment mechanism 3 needs to be operated to unlock it. The operation is very convenient. Moreover, when the gear adjustment mechanism 3 is adjusted back from the maximum angle position, it can lock the seat body 2 and the base 1 again. At this time, the seat body 2 cannot rotate relative to the base 1, which plays a secondary locking role, making it safer. Furthermore, when the reversing mechanism rotates the seat body 180 degrees from the original reversing position, the seat body rotates from facing forward to facing backward, which is the safest and most comfortable use angle in the field of safety seats, eliminating the need for further reversing adjustments to meet usage requirements.

[0047] like Figure 6 , Figures 19 to 22 As shown, the gear adjustment mechanism 3 allows the tilt angle between the seat body 2 and the base 1 to be between 0 and 14°. The adjustable tilt angle of the seat body 2 relative to the base 1 is between 0° and 14°.

[0048] like Figure 6 , Figures 19 to 22 As shown, the gear adjustment mechanism 3 allows the seat body 2 to be adjusted relative to the base 1 at four angle positions: the original angle position, the first angle position, the second angle position, and the maximum angle position. This allows for easy adjustment of the angle between the seat body 2 and the base 1, facilitating children's sitting or reclining positions.

[0049] like Figure 9 , Figures 23 to 25As shown, the reversing mechanism 4 allows the seat body 2 to rotate within a range of 0-360° relative to the base 1. The reversing mechanism 4 allows the seat body 2 to be adjusted to three reversing positions relative to the base 1: an initial reversing position, a first reversing position, a second reversing position, and a third reversing position, with an angle span of 90° between each reversing position. When the seat body 2 and base 1 are in the initial reversing position, the seat body 2 faces forward. When the seat body 2 and base 1 move from the initial reversing position to the first reversing position, the seat body 2 rotates relative to the base 1 and faces to the right. When the seat body 2 and base 1 move from the first reversing position to the second reversing position, the seat body 2 rotates relative to the base 1 and faces backward. When the seat body 2 and base 1 move from the second reversing position to the third reversing position, the seat body 2 rotates relative to the base 1 and faces to the left. The seat body 2 and base 1 can stop at four positions, making it more convenient to use.

[0050] Figures 3 to 8 As shown, the gear adjustment mechanism 3 includes multiple gear adjustment holes 31 disposed on the reversing mechanism 4 and corresponding to each included angle gear position. The seat body 2 is connected to an unlocking handle 32 that can slide back and forth relative to it. The seat body 2 is provided with a locking member 33 that can slide relative to it and engage or disengage from the gear adjustment holes 31. The locking member 33 and the seat body 2 are provided with a first elastic member 34 that can reset the locking member 33. The unlocking handle 32 and the seat body 2 are provided with a second elastic member 35 that can reset the unlocking handle 32. The gear adjustment holes 31 include a first gear adjustment hole 311, a second gear adjustment hole 312, a third gear adjustment hole 313, and a fourth gear adjustment hole 314 that correspond to the original included angle gear position, the first included angle gear position, the second included angle gear position, and the maximum included angle gear position, respectively. When the seat body 2 needs to adjust the angle relative to the base 1, pull the unlock handle 32. When the unlock handle 32 is pulled, it drives the locking member 33 to slide laterally relative to it. At this time, the locking member 33 gradually disengages from the first gear adjustment hole 311, the second gear adjustment hole 312, the third gear adjustment hole 313, or the fourth gear adjustment hole 313. At this time, the seat body 2 can slide relative to the base 1 and the reversing mechanism 4 to adjust the angle. After the seat body 2 rotates to the correct position relative to the base 1, release the unlock handle 32. The second elastic member 35 pulls the unlock handle 32 to reset. During the reset process of the unlock handle 32, the first elastic member 34 pushes the locking member 33, causing the locking member 33 to re-engage into the second gear adjustment hole 312, the third gear adjustment hole 313, the fourth gear adjustment hole 313, or the first gear adjustment hole 311 and complete the locking. At this time, the seat body 2 can no longer slide relative to the base 1 to adjust the angle.

[0051] Figures 3 to 8As shown, the latching member 33 includes a latching pin 331 slidably connected to the seat body 2. The latching pin 331 has a protrusion 332 that extends upward and is latched into the unlocking handle 32. The unlocking handle 32 includes a handle body 321 and an extension 322 that is connected to the handle body 321 and extends backward. The extension 322 has a groove 3221 for the latching pin 331 to slide inside. The extension 322 has a pressing oblique groove 3222 that allows the protrusion 332 to slide inside and presses against the protrusion 332 when the unlocking handle 32 slides, causing the latching pin 331 to disengage from the gear adjustment hole 31. When the handle body 321 is pulled, the extension 322 slides along with the handle body 321. At this time, the top-pressing inclined slide groove 3222 on the handle body 321 presses against the protrusion 332, causing the protrusion 332 to slide within the top-pressing inclined slide groove 3222. As the protrusion 332 slides, it drives the locking pin 331 to slide, causing the locking pin 331 to disengage from the gear adjustment hole 31, thus completing the unlocking. The locking pin 331 is located inside the seat body 2 and passes through the slide groove 3221.

[0052] Figures 9 to 18As shown, the reversing mechanism 4 includes a turntable 41 rotatably connected to the base 1. The base 1 is provided with a plurality of reversing positioning holes 42 that correspond to each reversing gear position. The turntable 41 is provided with a locking member 43 that can slide laterally relative to it and engage or disengage from the reversing positioning holes 42. The unlocking handle 32 is provided with a locking member 43 that can abut against the locking member 43 when the seat body 2 is in the original angle position, the first angle position, the second angle position, and the maximum angle position, thereby engaging the locking member 43. 3. The top abutment surface 44 remains locked within the reversing positioning hole 42. A third elastic element 45 is provided between the engaging member 43 and the turntable 41, which can push the engaging member 43 to slide relative to the engaging member 43, thereby disengaging the engaging member 43 from the reversing positioning hole 42. The unlocking handle 32 is provided with a clearance groove 46 that allows the engaging member 43 to disengage from the reversing positioning hole 42 when the seat body 2 is adjusted to the maximum angle position relative to the base 1 and the unlocking handle 32 is pulled to slide. When the engaging member 43 is in the locked state, the front end is inserted into the reversing positioning hole 42, and the rear end extends out of the turntable 41 and abuts against the top abutment surface 44 on the unlocking handle 32. When the seat body 2 needs to be rotated and reversed, first adjust the seat body 2 relative to the base 1 to the maximum angle position using the gear adjustment mechanism 3. At this time, the locking piece 33 is locked into the fourth gear adjustment hole 313. Then, continue to pull the unlocking handle 32 to slide. When the unlocking handle 32 slides, the locking piece 33 disengages from the fourth gear adjustment hole 313, and the engaging piece 43 gradually separates from the top surface 44 and gradually aligns with the clearance groove 46. When the engaging piece 43 aligns with the clearance groove 46, the third elastic member 45 pushes the engaging piece 43 to slide relative to the turntable 41. Since the locking piece 43 slides into the clearance groove 46, the locking piece 43 has enough distance to disengage from the reversing positioning hole 42. At this time, the reversing mechanism 4 is unlocked, and the seat body 2 can rotate relative to the base 1 via the turntable 41. The unlocking operation is convenient. Moreover, when the seat body 2 moves relative to the base 1 from the maximum angle position to the original angle position, the first angle position, and the second angle position, even if the unlocking handle 32 is pulled, the clearance groove 46 cannot be aligned with the locking piece 43. Therefore, it can play the role of a double lock, making it safer for infants and young children to ride.

[0053] Figures 9 to 18 As shown, the engaging member 43 includes a first pin 431 that can slide laterally relative to the turntable 41. A second pin 432 is mounted on the first pin 431 and is vertically aligned with it. The third elastic member 45 has its two ends abutting against the second pin 432 and the wall of the turntable 41, respectively. The third elastic member 45 is compressed when the reversing mechanism 4 is locked. When the first pin 431 aligns with the clearance groove 46, the third elastic member 45 pushes against the second pin 432, causing the entire engaging member 43 to slide into the clearance groove 46.

[0054] Figures 9 to 18 As shown, the base 1 has a connecting seat 11 that protrudes upward and extends into the turntable 41. Multiple reversing positioning holes 42 are provided on the connecting seat 11, and the turntable 41 has a slot 411 for the connecting seat 11 to be engaged. The cooperation between the connecting seat 11 and the slot 411 ensures a more stable and secure connection.

[0055] Figures 3 to 5 As shown, the turntable 41 includes a rotating seat 412 connected to the base 1 and a connecting piece 413 connected to the base 1. The seat body 2 is provided with a first crossbar 5 through which the connecting piece 413 passes laterally. The connecting piece 413 is provided with a first limiting groove 4131 in which the first crossbar 5 can slide. A second crossbar 6 is provided laterally between the seat body 2, the connecting piece 413 and the unlocking handle 32. The connecting piece 413 is provided with a second limiting groove 4132 in which the second crossbar 6 can slide. The unlocking handle 32 is also provided with a third limiting groove 323 in which the second crossbar 6 can slide. The third limiting groove 323 is provided with a pushing surface 3231 that can push the second crossbar 6 to slide in the second limiting groove 4132 when the unlocking handle 32 is pulled. When the seat body 2 slides relative to the base 1 to adjust the angle position, the unlocking handle 32 is pulled, causing the push surface 3231 on the third limiting groove 323 to push the second crossbar 6 to slide. When the second crossbar 6 slides, the seat body 2 slides together and drives the first crossbar 5 to slide in the first limiting groove 4131.
