Detailed Description

The present invention will be further described with reference to the following detailed description, and it should be noted that, in the premise of no conflict, the embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

The utility model provides a children's safety seat's rotary mechanism and including this rotary mechanism's children's safety seat.

The rotation mechanism of the child safety seat shown in fig. 1 to 4 includes a base 1, a turntable 2 rotatably provided on the base 1, and a locking unit 3 for locking or unlocking the rotation of the turntable 2.

As shown in fig. 5 and 6, the side wall of the turntable 2 has a plurality of positioning grooves 21 in the circumferential direction. The locking unit 3 selectively engages one of the positioning slots 21 to hold the turntable 2 in a rotational position corresponding to that positioning slot 21, and fig. 2, 3 and 4 show three rotational positions of the turntable 2, it being noted that the rotational positions shown in fig. 2, 3 and 4 are merely illustrative and not exhaustive. The seat portion 4 of the child safety seat is adapted to be arranged on the turntable 2, so that the orientation of the seat portion 4 is adjusted under the driving of the turntable 2.

The locking unit 3 includes a moving member 31 and an elastic restoring member (not shown in the figure), and the moving member 31 is slidably disposed on the base 1, so that the moving member 31 slides to approach or depart from the turntable 2. The moving member 31 is adapted to be inserted into the positioning slot 21 corresponding to the moving member to lock the turntable 2, and the elastic restoring member is adapted to continuously apply an acting force to the moving member 31 to make it close to the turntable 2.

In the initial state, the moving member 31 is inserted into a positioning groove 21 of the turntable 2, and the turntable 2 is locked; when an external force (which may be an external force directly applied to the moving member 31 by an operator or an external force applied to the moving member 31 through the turntable 2 as described later) overcomes the acting force of the elastic restoring member, so that the moving member 31 is far away from the turntable 2, the moving member 31 is separated from the corresponding positioning groove 21, and the turntable 2 can freely rotate relative to the base 1; when removing external force, moving member 31 moves to carousel 2 under the effect of elasticity piece that resets, it is all relative with moving member 31 that arbitrary constant head tank 21 of carousel 2 is possible this moment, the effect of the elasticity piece that resets of moving member 31 supports in the lateral wall of carousel 2 down, carousel 2 still can free rotation, continue to rotate carousel 2 and make a constant head tank 21 relative with moving member 31, moving member 31 moves to constant head tank 21 under the effect of elasticity piece that resets, also in moving member 31 inserts constant head tank 21, with carousel 2 locking.

A plurality of constant head tank 21 on carousel 2 are work constant head tank 211 and pause constant head tank 212 respectively, and when carousel 2 received the tangential effort, work constant head tank 211 could not make moving member 31 roll-off work constant head tank 211 to the effort that moving member 31 applyed, and when the tangential effort that carousel 2 received was greater than a definite value, the effort that pause constant head tank 212 applyed moving member 31 made moving member 31 roll-off pause constant head tank 212. The number of the working positioning grooves 211 and the number of the pause positioning grooves 212 may be the same or different, and the distance between two adjacent positioning grooves 21 may be the same or different. When the moving member 31 is inserted into the working positioning groove 211, the turntable 2 and the seat portion 4 provided on the turntable 2 are in the working position, and when the moving member 31 is inserted into the pause positioning groove 212, the turntable 2 and the seat portion 4 provided on the turntable 2 are in the pause position.

There are two cases of locking of the turntable 2 by the locking unit 3: in the first situation, the locking unit 3 locks the turntable 2 with high stability, and at this time, the moving member 31 is inserted into the working positioning groove 211, and in this locking state, the unlocking can be completed only by manually sliding the moving member 31 by an operator; under the second condition, the locking unit 3 locks the turntable 2 in a stable and low locking state, and the moving member 31 is inserted into the pause positioning groove 212, in this locking state, the operator can directly act on the moving member 31 to unlock the turntable by sliding, and can also apply a certain tangential acting force to the turntable 2 (or the seat part 4 connected with the turntable 2 in a rotating manner), so that the acting force of the turntable 2 on the moving member 31 can overcome the elastic force of the elastic reset member, and the moving member 31 slides out of the pause positioning groove 212 to unlock the turntable.

In other words, the moving member 31 inserted into the working positioning groove 211 cannot slide out of the working positioning groove when the turntable 2 is subjected to a tangential force, and if the turntable 2 or the seat portion 4 located at the working position is to be rotated to other positions, the operator needs to manually slide the moving member 31 to unlock the seat, so that the stability of the turntable 2 and the seat portion 4 at the working position is increased. The moving member 31 inserted into the pause positioning slot 212 is adapted to slide out of the pause positioning slot 212 along the sidewall when the turntable 2 is subjected to a certain tangential force, and if the turntable 2 or the seat portion 4 located at the pause position is to be rotated to other positions, a user can automatically slide out of the pause positioning slot 212 to unlock the seat by applying a certain tangential force to the turntable 2 (or the seat portion 4) without manually operating the moving member 31.

In some embodiments, the positioning groove 211 is a straight cylinder extending along the radial direction of the turntable 2, and when the turntable 2 is subjected to a tangential force, the force applied by the positioning groove 211 to the moving member 31 generates no component force in the sliding direction of the moving member 31, so that the moving member 31 does not slide out of the positioning groove 211.

In some embodiments, an outward inclined guide surface is formed at the opening of the pause positioning slot 212, and the distance between the two side walls of the pause positioning slot 212 gradually increases from inside to outside, that is, the opening of the pause positioning slot 212 is in an outward trumpet shape, and when the tangential acting force applied to the turntable 2 exceeds a certain value, the acting force applied to the moving member 31 by the pause positioning slot 212 generates a component force in the sliding direction of the moving member 31, so that the moving member 31 can slide out of the pause positioning slot 212 along the guide surface. Preferably, two sides of an end of the moving member 31 opposite to the pause positioning groove 212 are also formed with inclined surfaces, and when the moving member 31 is inserted into the pause positioning groove 212, the inclined surfaces of the moving member 31 are attached to the guide surfaces of the pause positioning groove 212.

In one embodiment, as shown in fig. 6, the turntable 2 includes two working positioning slots 211 and two temporary positioning slots 212, the working positioning slots 211 and the temporary positioning slots 212 are disposed at intervals, and the positioning slots are distributed at equal intervals along the circumference. At this time, the working position is a position where the seat portion 4 faces directly forward or directly backward, and the seat portion 4 provides a safer protection for the child. The pause position is a position where the seat portion 4 is oriented to the left or right, and the protection of the child by the seat portion 4 thus placed is relatively poor, so it is not preferable to keep the seat portion 4 in such a position when the vehicle is running, but when the vehicle is stopped, turning the seat portion 4 to the pause position facilitates the user to place the child from the door or to take care of the child on the seat.

In one embodiment, as shown in fig. 7-10, the base 1 has a turntable mounting cavity 10 and a base front end 11 located in front of the turntable mounting cavity 10, the turntable mounting cavity 10 being used for mounting the turntable 2. As shown in fig. 8, the base front end 11 is provided with two parallel sliding grooves 13, the two sliding grooves 13 extend from the base front end 11 to the turntable mounting cavity 10, and two sides of the moving member 31 are slidably disposed in the two sliding grooves 13, so that the moving member 31 can slide back and forth under the limit of the two sliding grooves 13.

As shown in fig. 11, the moving member 31 has an operating end 311 and a locking end 312, the operating end 311 is located at the front end 11 of the base, the locking end 312 extends toward the side wall of the turntable 2, and a user can slide the moving member 31 through the operating end 311, so as to drive the locking end 312 to be inserted into the positioning slot 21 located at the side wall of the turntable 2 or separated from the positioning slot 21.

As shown in fig. 7-10, an operation window 110 is formed on the upper end surface of the front end 11 of the base, the sliding chute 13 and the moving member 31 are both disposed on the bottom surface of the front end 11 of the base, and the operation end 311 of the moving member 31 is opposite to the operation window 110, so that a user can operate the operation end 311 through the operation window 110. The operation end 311 has a notch 3110 formed thereon, and a user is adapted to apply force to the moving member 31 through the notch 3110. When the moving member 31 slides, the groove 3110 moves from one end to the other end of the operation window 110.

In some embodiments, the locking unit 3 further comprises a micro switch 33, as shown in fig. 8, the micro switch 33 being used to detect the movement of the moving member 31. A detection cavity 310 is formed on the moving member 31, one end of the micro switch 33 is fixed on the bottom surface of the base 11, and the other end extends into the detection cavity 310.

The degree of depth of work constant head tank 211 is greater than the degree of depth of pause constant head tank 212, and when moving member 31 inserted in work constant head tank 211, the inner wall that moving member 31 detected chamber 310 acted on micro-gap switch 33, made micro-gap switch 33 be in first state, and when moving member 31 outwards slided from work constant head tank 211, moving member 31 separated with micro-gap switch 33 all the time, and micro-gap switch 33 is in the second state all the time. It should be noted that when the moving member is inserted into the pause positioning slot 212, the inner wall of the detection cavity 310 of the moving member 31 is separated from the micro switch 33, so that the micro switch 33 is in the second state at this time.

The rotating mechanism of the child safety seat further comprises an alarm device in signal connection with the microswitch 33, when the microswitch 33 is in a first state, the alarm device gives an in-position prompt, and when the microswitch 33 is in a second state, the alarm device gives a non-in-position prompt. In other words, the alarm device will only give the indication of the position when the moving member 31 of the locking unit 3 is inserted into the working positioning groove 211, and the alarm device will give the indication of the position missing in other states.

The alarm device may include an audible alarm unit (not shown) that does not sound or only sounds an audible indication when the microswitch is in the first state, and that continues to sound when the microswitch is in the second state to alert the user that the seat portion has not been rotated to the operating position.

The alarm device may further comprise a light-emitting alarm unit 5, the light-emitting alarm unit 5 emitting light of a first color when the microswitch 33 is in the first state and emitting light of a second color when the microswitch 33 is in the second state. Alternatively, the light-emitting alarm unit 5 may continuously emit light when the microswitch 33 is in the first state, and may intermittently emit light (i.e., the light may blink) when the microswitch 33 is in the second state.

It is worth mentioning that the micro switch 33 and the alarm device are powered by a power source, which may be a battery, a vehicle-mounted power source, etc.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
