Description

child safety seat

technical field

The invention relates to the technical field of children's products, in particular to a child safety seat suitable for use with an anchor of a vehicle.

Background technique

A child safety seat is a device that is tied to a car seat and restrains a child on it through a restraint device. Compared with a car airbag, a child safety seat can reduce the risk of emergency braking or accidental collision of a child in a car. The chance of being harmed is lower, so it is quickly accepted by consumers and slowly promoted all over the world.

In order to facilitate the use of child safety seats, many cars are currently equipped with anchors of the ISOFIX (International Standards Organization FIX, child safety seat fixing system) structure at the factory. In this way, child safety seat manufacturers install corresponding anchors on child safety seats. The ISOFIX structure of the lock allows the child safety seat to be easily fixed to the anchor of the car, and the child safety seat needs to be fixed with a messenger strap (sometimes only a lap belt) after it is placed on the car seat . However, different car models have different seats, safety belts, and fixing methods. Different car seat shapes, shorter belt lengths, and different anchor point locations can lead to child safety seats being positioned further forward or further back, making it a challenge to manufacture a child safety seat that fits all car models.

In order to solve the above problems, most of the current child safety seats are designed with adjustment structures to adapt to the seats of various car models. However, the current child safety seats that can be adjusted forward and backward all have defects such as complicated structural design and inconvenient operation.

Therefore, it is necessary to provide a child safety seat that is simple in structure and can be easily adjusted by users, so as to solve the above-mentioned deficiencies in the prior art.

The column 1331 disengages from the recessed hole 1341 of the telescopic element 134 , that is, the convex column 1331 is at the second position at this time, so that the telescopic adjustment of the locking element 150 can be realized.

Preferably, the connecting piece 135 is connecting plastic, one end of the connecting plastic is fixed on the end of the telescopic piece 134, and the other end is sleeved outside the horizontal tube 140 and fixed thereto. Of course, the connecting piece 135 does not This is the limit.

Referring again to Figures 3-5, one end of the operating member 131 forms an operating end 1311, the other end of the operating member 131 forms a driving end 1312, and the driving end 1312 is provided with the slope 1313; the operating member 131 is connected to After the bottom tube 136 is installed, the operating end 1311 is adjacent to the front end of the seat body 110, the driving end 1312 is adjacent to the rear end of the seat body 110, and the inclined surface 1313 is connected with the plate 1332. By operating the operating end 1311 And make the operating part 131 slide along the telescopic direction, so that the inclined surface 1313 pushes the plate 1332 to undergo elastic deformation, and drives the convex post 1331 to break away from the concave hole 1341 on the telescopic part 134. The tube 140 makes the telescopic member 134 expand and contract, so as to realize the telescopic adjustment of the locking member 150 .

Specifically, the bottom tube 136 is provided with a limiting groove 1361 along its length direction, and the operating member 131 is slidably accommodated in the limiting groove 1361 . One end of the plate 1332 has a fixing portion 1333, through which the plate 1332 is fixed to an end of the bottom pipe 136 adjacent to the rear end of the seat body 110, the plate 1332 extends toward the front end of the seat body 110, and the plate 1332 The piece 1332 covers the limiting groove 1361 of the bottom tube 136 and corresponds to the inclined surface 1313 of the operation member 131 .

Since the plate 1332 is made of elastic material, its own deformation is elastic deformation. Therefore, when the push of the inclined surface 1313 is cancelled, the plate 1332 can be reset by its own elasticity, so that the boss 1331 is re-engaged into the new The recessed hole 1341, and the protrusion 1331 has a constant tendency to engage in the recessed hole 1341.

Referring to Fig. 4-Fig. 7, the middle part of the boss 1331 has a positioning protrusion 1331a (see Fig. 7 ), which protrudes perpendicularly to its body. hole 1335, one end of the boss 1331 is accommodated in the installation hole 1335, and one side of the positioning protrusion 1331a is against the driven slope 1334, and the other side of the positioning protrusion 1331a is against the driving end 1312; the other side of the protrusion 1331 One end passes through the through hole 1362 on the bottom tube 136 to engage with the concave hole 1341 of the telescopic member 134 .

In this embodiment, a plurality of concave holes 1341 are evenly opened along the telescopic direction of the telescopic member 134, and the protrusion 1331 is detachably engaged in any one of the concave holes 1341; therefore, when the operating member 131 is pulled When operating the end 1311, the operating member 131 slides so that the inclined surface 1313 pushes against the driven inclined surface 1334, thereby driving the plate 1332 to undergo elastic deformation, and the plate 1332 is elastically deformed to drive the fixed post 1331 to break away from the telescopic member 134 The concave hole 1341 on the top, so that the lock 150 can be telescopically adjusted; during the above process, the plate 1332 is elastically deformed; into other concave holes 1341 on the telescopic piece 134 to realize the positioning of the locking piece 150 .

In addition, in this embodiment, the first return member 132 is a tension spring, and the two ends of the tension spring are respectively connected to the end of the operation end 1311 and the end of the bottom pipe 136 (see Figure 6); thus, when the operation end When 1311 is pulled, the extension spring is stretched to produce a tension effect. When the operation on the operating end 1311 is cancelled, the extension spring recovers and deforms to reset the operating member 131, thereby canceling the thrust of the inclined surface 1313 on the driven inclined surface 1334, so that the convex The post 1331 can be snapped into another concave hole 1341 again, and the protruding post 1331 has a constant tendency to snap into the concave hole 1341 .

Because the child safety seat 100,200 of the present invention includes a seat body 110,210, a telescopic adjustment mechanism 130,230 and a lock 150,250; the telescopic adjustment mechanism 130,230 is arranged on the seat body 110,210 and the lock 150,250 between, so as to realize the telescopic adjustment of the lock 150, 250 relative to the seat body 110, 210; wherein, the telescopic adjustment mechanism 130, 230 includes a telescopic piece 134, 234, a pin 133, 233 and an operating piece 131, 231; The telescopic parts 134, 234 are connected to the seat body 110 to move along the telescopic direction and have a plurality of concave holes 1341, 2341 arranged along the telescopic direction. The lock parts 150, 250 are installed on the telescopic parts 134, 234; the pin parts 133, 233 It has a first position and a second position, wherein, when the pins 133, 233 are in the first position, the pins 133, 233 are engaged with the concave holes 1341, 2341, so as to prohibit the telescopic member 134 , 234 telescopic adjustment, when the pins 133, 233 are located at the second position, the pins 133, 233 break away from the concave holes 1341, 2341 to allow the telescopic adjustment of the telescopic parts 134, 234; the operating parts 131, 231 extend along the Direction movement is connected to the seat body 110 and includes slopes 1313, 2314 that interfere with the pins 133, 233, wherein, by operating the slopes 1313, 2314 to move, the pins 133, 233 are driven along the staggered The action direction of the telescopic direction moves between the first position and the second position; therefore, the child safety seat 100, 200 of the present invention can be adjusted conveniently and quickly, and has a simple structure and easy operation.

What is disclosed above is only a preferred embodiment of the present invention, and of course it cannot limit the scope of rights of the present invention. Therefore, equivalent changes made according to the patent scope of the present invention still fall within the scope of the present invention.
