Description

[0001] This application is a divisional application of the invention patent application whose applicant is Baoju Switzerland AG, with an application date of January 6, 2021, application number 202110017031.8, and invention name is "Adjustable front guard and car safety seat". Technical Field

[0002] The invention relates to a baby carrier, and in particular to an adjustable front protector and a car safety seat. Background Art

[0003] Some car safety seats have a front guard structure, which is generally slidably inserted between the seat and the armrest, and then the car's safety belt is wrapped around the front guard and the seat body, so that the front guard is positioned on the seat body to protect the child. When different children are riding, since there is no connection mechanism between the front guard and the seat body, it is only necessary to pull the front guard forward a certain distance and then loosen the safety belt to achieve the purpose of adjusting the seat space.

[0004] However, this adjustment method may cause the front guard to separate from the seat body, making the positioning of the front guard unreliable and prone to accidents. Currently, there is a car safety seat that has a detachable connection mechanism designed at the rear end of the front guard, so that the front guard can be fixed between the seat and the armrest. However, this connection method will cause the front guard to be unadjustable relative to the seat body, resulting in the seating space of the car safety seat being unadjustable. For children of different ages, it cannot adapt to the body shape of children, and larger children cannot use this car safety seat. Summary of the invention

[0073] See also Figures 17 to 19 The adjustable front guard 500 of this embodiment is similar to that of the first embodiment, and includes a fixed seat 510, a sliding portion 520 and a locking mechanism 530. The sliding portion 520 is slidably disposed on the fixed seat 510 along the ascending direction from the back to the front, and the locking mechanism 530 is disposed between the fixed seat 510 and the sliding portion 520 to lock or unlock the sliding portion 520. A guide groove 521 is disposed on the side of the fixed seat 510, and the guide groove 521 is a sliding tube. A guide rail 511 extending along the ascending direction from the back to the front is disposed on the side of the sliding portion 520, and the guide rail 511 is a fixed tube, and the sliding tube is slidably sleeved outside the fixed tube.

[0074] Please see again Figure 20 to Figure 21 The locking mechanism 530 includes two clamping rods 531, a driving block 532, an operating member 533 and an elastic element (not shown in the figure). The clamping rods 531 are respectively slidably arranged on the sliding part 520. The fixing seat 510 is provided with at least two clamping holes 512 along the ascending direction from the back to the front, and the clamping holes 512 are located on the fixing tube. The clamping rod 531 is selectively inserted into any of the clamping holes 512. Specifically, the driving block 532 is slidably arranged on the sliding part 520, and the sliding direction is perpendicular to the sliding direction of the clamping rod 531; the driving block 532 is provided with two driving inclined grooves 5321, and the extension directions of the two driving inclined grooves 5321 are symmetrically arranged. A sliding pin 5311 is fixedly arranged at one end of the clamping rod 531, and the central axis of the sliding pin 5311 is perpendicular to the central axis of the clamping rod 531, and the sliding pin 5311 is slidably inserted into the driving inclined groove 5321. The operating member 533 is connected to the driving block 532 and can pull the driving block 532 to move. The elastic element is disposed between the sliding portion 520 and the clamping rod 531 and provides an elastic force to insert the clamping rod 531 into the clamping hole 512. The elastic element can be a compression spring.

[0075] When the position of the front guard 500 needs to be adjusted, the operating member 533 only needs to be manually pulled to make the operating member 533 drive the driving block 532 to move, and the driving block 532 drives the two clamping rods 531 to withdraw from the clamping holes 512 through the two driving inclined grooves 5321 and the sliding pin 5311. At this time, the sliding part 520 is in a unlocked state, and the sliding part 520 can slide relative to the fixing seat 510. After the position of the sliding part 520 is adjusted, the operating member 533 is released, so that the clamping rod 531 extends into the corresponding other clamping hole 512, and then the sliding part 520 is locked again, and the adjustment is completed.

[0076] like Figure 22 to Figure 24 As shown, the figure shows the structure of the adjustable front guard 600 of the fifth embodiment of the present invention.

[0077] The structure of the adjustable front guard 600 of this embodiment is similar to that of the fourth embodiment, except that the locking mechanism 630 of this embodiment includes a clamping rod 631, an operating member 632 and an elastic element 633. The clamping rod 631 is slidably disposed on the sliding portion 620 and can extend out of the outside of the sliding portion 620. The fixing seat 610 is provided with at least two engaging holes 612 along the ascending direction from the back to the front, and the clamping rod 631 is selectively inserted into any of the engaging holes 612. The operating member 632 is connected to the clamping rod 631 and is slidably disposed in the sliding portion 620. Specifically, the sliding portion 620 is provided with a guide rod 634 balanced with the clamping rod 631, and the operating member 632 is slidably sleeved on the guide rod 634. In this way, the operating member 632 can be prevented from accidentally deviating and the stability of the structure can be improved. The end of the operating member 632 is exposed at the front side of the sliding portion 620 for easy operation. The elastic element 633 is disposed between the two clamping rods 631 on the left and right sides to provide an elastic force to insert the clamping rod 631 into the clamping hole 612. The elastic element 633 can automatically insert the clamping rod 631 into the clamping hole 612, so that the sliding part 620 is automatically locked with the fixing seat 610, thereby improving the convenience of use. When operating this embodiment, it is only necessary to push the operating member 632 so that the operating member 632 drives the clamping rod 631 to exit the fixing seat 610 to achieve the purpose of unlocking the sliding part 620, thereby realizing the rapid adjustment of the position of the sliding part 620.
