Problems solved by technology

However, further observations by the applicant and experiments have shown that the above-mentioned car seat recliner still has the following deficiencies: the first is the disengagement between a group of small tooth plates (usually three evenly distributed) and the tooth plate It is performed by the driving mechanism of the small tooth plate. Therefore, when there is no external force, the three small tooth plates will pass through the convex pin extended on the small tooth plate and the convex pin groove on the drive plate under the action of the spring force. Cooperate to ensure that the meshing of the small tooth plate and the tooth plate is in a locked state, the seat back and the seat of the car seat are in a relative use state, and the driving mechanism is through the convex pin groove on the drive plate and the pinion on the small tooth plate. The convex pins cooperate, so the rotation of the drive plate drives the sliding of the small tooth plate to realize the meshing of the small tooth plate and the tooth plate. In this locked state, the convex pin of each small tooth plate and the convex pin groove of the drive plate Because there is only one force-bearing contact surface between the groove walls, the cooperation between the drive plate and the small tooth plate and various components is prone to gaps
Due to the lack of structural cooperation between the three small tooth plates and the drive disc, the fit gap between the small tooth plates and the drive disc cannot be ensured, thus affecting the reliability of the action and the clearance and strength of the entire recliner
[0003] As another example, the Chinese Utility Model Patent Authorization Notice No. CN2712705Y (applied by the applicant) discloses a "universal recliner". Its achievements are: high locking strength, small displacement angle, wide adjustment range, The advantages of small axial clearance, good balance, simple structure, small size, and convenient installation, but the following problems are exposed in the actual use process: because the small tooth plate and the cam plate are located in the sliding groove of the fixed plate to form a straight line Movement, and the locking and disengagement of the recliner is realized through the action between the lug grooves of the small tooth plate and the lugs on both sides of the cam plate, so the requirements for the machining accuracy of the parts are high, and the clearance of the recliner is consistent Difficult to control

Abstract

The invention relates to a car seat angle adjuster with an improved structure, belonging to car seat accessories. The car seat angle adjuster comprises a gear disc base, a gear disc, pinion plates, a pinion plate driving mechanism and a closed ring, wherein the gear disc base is circular, is axially provided with a first axle hole in center and is also provided with a first locating boss at one side, and three pinion plate locating bosses at the other side, and a sliding groove is formed between two adjacent pinion plate locating bosses; the gear disc is circular, is axially provided with a second axle hole in center, is provided with a gear ring and an accommodating cavity, and is also provided with a second locating boss at the other side; the pinion plate driving mechanism comprises a cam plate, a central shaft and a spring; the three pinion plates are located in the sliding grooves and are provided with gear teeth, lug grooves and bottom edges; and the closed ring is sealed aroundthe gear disc base and the gear disc. The invention has the advantages of uniform movement of all the pinion plates, reliable locking, small gap, convenient unlocking, high strength, small size, simple structure, convenient assembly, low production cost and wide application scope.

Description

Technical field [0001] The present invention relates to a seat back and seat used to be installed between the seat back and the seat, which can properly adjust the angle between the seat back and the seat, and is an improvement on the structure of the existing car seat angle adjuster , Belongs to the technical field of car seat accessories. Background technique [0002] The function of the car seat recliner is as mentioned above, and it is responsible for changing the forward and backward angle of the seat back. As this kind of device, it is necessary for the car seat. As far as the structure of the angle adjuster is concerned, there must be a pair of toothed plates, that is, a set of small toothed plates and a toothed plate, which act on the cam plate by applying force on the transmission component such as a shaft, and then the cam plate acts on a toothed plate. For the gear plate, the small gear plate is separated from the gear plate to realize the adjustment of the seat back;...
