Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

A child car safety seat according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

The utility model provides a children's car safety seat, as in the example shown in fig. 1, it includes base 1 and bears frame 2, and base 1's rear end is equipped with and is used for carrying out removable assembly's connecting piece with the fixed seat on the vehicle, so that children's car safety seat's base 1 can be fine fix on the seat of car back row, this is the conventional design that current safety seat installed on the vehicle, so do not just do not describe in detail to this connecting piece. The safety seat is based on the differential design that: base 1's front end is equipped with support piece, and support piece's one end links to each other with base 1 is fixed, and support piece's the other end extends down and forms the strong point for step on the part with the foot in the car and lean on, realize from this that it more is favorable to when the vehicle bumps the utility model discloses this children car safety seat's of application base 1 can obtain the pulling force support of base 1 rear end connecting piece promptly and can obtain support piece's support again, consequently the existing safety seat who only realizes the installation through the padlock of connecting piece, and its security performance is promoted. Especially for safety seats which are partly pivotable carrying carriages so that the carrier 2 is oriented adjustably, the supporting effect of the support elements on the base 1 is more important than the tightening effect of the connecting elements on the base 1, since the centre of gravity of the carrier 2 is located closer to the front end of the base 1 when the safety seat is arranged in a position in which the carrier 2 is oriented rearwards, as it is adapted to young children. The step portion may be a mat laid in the vehicle, or a frame or a floor panel of the vehicle.

The first embodiment is as follows:

the basic structure of this embodiment is similar to the above-mentioned children's car safety seat, and the difference lies in: the supporting piece is movably connected with the base 1. The movable connection of the support member to the base 1 thus enables one end of the support member to be connected to the base 1 while the other end of the support member is adjustable in position. From the completion of the switching of the support member between the support position and the collapsed position, the position of the support member may of course be more, and it may be switched between different positions as the support member is moved.

In particular, the support as shown comprises a main bar 3 and a strut 4.

One example of this is: as shown in fig. 1-3, the main rod 3 is matched with the guide rail 5 arranged along the horizontal direction on the base 1, so that the main rod 3 can be drawn on the base 1, that is, the main rod 3 is inserted into the base 1 to the limit position along the horizontal direction, so that most of the main rod 3 is accommodated in the base 1 and only the end of the main rod 3 is left to be exposed, the branch rod 4 is arranged along the vertical direction, the upper end of the branch rod 4 is hinged with the exposed end of the main rod 3, thereby the whole branch rod 4 can swing around the hinged point, and finally the branch rod 4 swings to the supporting position in the vertical direction or to the folding position in the horizontal direction.

Preferably, in this example, in order to enable the strut 4 to be well concealed also in the collapsed position, the strut 4 and the main bar 3 are swung in the same vertical plane, i.e. the strut 4 and the main bar 3 are brought together when the strut 4 is swung to assume a horizontal orientation. As shown in fig. 2, when the length of the strut 4 is greater than that of the main rod 3, it is preferable that a receiving groove 10 matching with the strut 4 is provided at the bottom of the base 1, and a part of the strut 4 is received in the receiving groove 10 when the strut 4 is in the folded position.

The second example is: guide rail 5 that follow the horizontal direction setting on mobile jib 3 and the base 1 cooperatees, so that mobile jib 3 can be made the pull motion on base 1, and mobile jib 3 inserts extreme position so that most of mobile jib 3 accomodate in base 1 and only leave the tip of mobile jib 3 and expose along the horizontal direction in base 1 promptly, branch 4 sets up along vertical direction, the upper end of this branch 4 and the exposed tip fixed connection of mobile jib 3. Although it is not mobilizable in this example between branch 4 and mobile jib 3 but can make branch 4 also link along with the flexible of mobile jib 3, consequently also can play the regulation to branch 4 position, consequently is applicable under partial scene, then can adopt when for example only need do the design consideration of fine setting around the position of strong point and need not do whole folding the utility model discloses this example scheme of application. The advantage of this example is that the movement between the mast 3 and the mast 4 is reduced, so that the connection between the mast 3 and the mast 4 is more secure.

The third example is: one end and the base 1 fixed connection of mobile jib 3, branch 4 sets up along vertical direction, and the upper end of this branch 4 is articulated with the other end of mobile jib 3, makes whole branch 4 can be around this pin joint swing from this, finally makes the branch 4 swing be the support position of vertical direction or swing to the position of folding that is the horizontal direction.

Preferably, in this example, in order to enable the strut 4 to be well concealed also in the collapsed position, the strut 4 and the main bar 3 are swung in the same vertical plane, i.e. the strut 4 and the main bar 3 are brought together when the strut 4 is swung to assume a horizontal orientation. If the length of the branch 4 is larger than that of the main rod 3, the bottom of the base 1 is provided with an accommodating groove 10 matched with the branch 4, and when the branch 4 is in the folding position, part of the branch 4 is accommodated in the accommodating groove 10.

The fourth example is: as shown in fig. 14, one end of the boom 3 is rotatably fitted to the base 1 in the horizontal direction so that the position of the boom 3 in the horizontal plane is adjustable, whereby the boom 3 can be switched between the operating position and the storage position. Branch 4 sets up along vertical direction, and the upper end of this branch 4 and the free end that deviates from base 1 of mobile jib 3 are along vertical direction normal running fit, and the lower extreme of branch 4 is vertical state or rotates to being the horizontality along with branch 4 rotates. Then rotate mobile jib 3 when needs expand mobile jib 3 and branch 4 to make the free end of mobile jib 3 be in the farthest end of base 1, make the rotation between mobile jib 3 and the base 1 receive the restriction through the retaining member this moment, then along vertical direction upset branch 4 again, make branch 4 swing down to being vertical state, the same rotation that makes between mobile jib 3 and branch 4 through another retaining member also receives the restriction, has accomplished whole support piece's expansion this moment. On the contrary, if the support piece in the unfolded state needs to be folded, the two locking pieces are unlocked, the main rod 3 is reset and rotated so that the free end of the main rod 3 is close to the base 1, and the whole main rod 3 is attached to the side wall of the base 1; the lower end of the strut 4 is turned upwards so that the strut 4 is reset from the vertical state to the horizontal folded state. Of course, the sequence of the folding of the supporting rod 4 and the rotation of the main rod 3 is not strictly distinguished, and can be arbitrarily selected according to the actual situation. In addition, in order to avoid the self-release of the pole 4 or the main rod 3 when the pole 4 and the main rod 3 are both in the folded state, an additional fixing member is required for fixing the pole 4 and the main rod 3, which may be a fastening member 11, a snap member, a strap, or the like, and the existing standard members are not unfolded one by one in the present embodiment.

Example two:

although the support applied to the child car safety seat should not be able to be detached by the user's bare hand under the safety requirements, which are based on the legal requirements of safety, it is not excluded that the support is detachable after the related art safety technology is developed. Therefore, the application of the present invention should not exclude this possibility. The basic structure of this embodiment is similar to the above-mentioned children's car safety seat, and the difference lies in: the supporting member and the base 1 are detachably connected.

One example of the embodiment is that the support member and the base 1 can be detached by hand, and specifically includes that the upper end of the support member is connected by a snap manner, or is connected by a fastener 11 in an inserting manner.

One example of this embodiment is that the support member and the base 1 need to be disassembled by a tool, and specifically includes that the upper end of the support member is detachably connected to the base 1 by a screw or a bolt.

Example three:

the improvement point of the embodiment is that: the support member includes a main rod 3 and a support rod 4, wherein the support rod 4 is a multi-section telescopic rod, specifically, two sections as shown in fig. 1, or three or more sections. The telescopic strut 4 of the third embodiment may be incorporated into the first or second embodiment.

This prior locking mechanism may employ a variety of conventional techniques, and therefore will not be described in detail.

As shown in fig. 6 and 7, no extra operation action is required to be performed by an operator in order to realize the locking and unlocking of the locking mechanism, so that the situation that the operator forgets to lock the locking mechanism and the locking mechanism is not locked between the main rod 3 and the base 1 is avoided, and the safety problem is caused thereby is avoided, therefore, the embodiment of the present invention provides a preferred locking mechanism: the locking mechanism is switched between a locked state and an unlocked state in response to the swinging action of the strut 4. Specifically, the locking mechanism is in an unlocked state when the strut 4 is placed in the receiving slot 10 of the base 1, the locking mechanism is switched to a locked state when the strut 4 is swung out of the receiving slot 10 until the free end of the strut 4 is disengaged from the receiving slot 10, or the locking mechanism is switched from the unlocked state to the locked state when the strut 4 is swung to the fully deployed position as shown in fig. 6. On the other hand, the effect to be achieved by this embodiment is that only when the supporting rod 4 is in the folded position, the locking mechanism needs to be in the unlocked state to facilitate the movement of the main rod 3, and when the supporting rod 4 is in the fully unfolded position, the stable connection relationship among the supporting rod 4, the main rod 3 and the base 1 needs to be formed, so that the main rod 3 and the base 1 need to be locked by the locking mechanism. And the timing of the switching of the locking mechanism during the swinging of the strut 4 between the folded position and the fully unfolded position can be selected based on actual requirements.
