Abstract

The invention relates to the technical field of car parts, in particular to a headrest assembly of a child car seat. A headrest sliding device connected with a headrest body is arranged in a backrest; the headrest sliding device comprises a sliding plate, a sliding sleeve arranged on the sliding plate in a sleeving mode, a fixing pin arranged on the sliding sleeve and a spring arranged on the fixing pin in a sleeving mode; a plurality of inserting holes which are sequentially distributed in the vertical direction and matched with the fixing pin are formed in the sliding plate; the fixing pin is inserted into the sliding cover, and two flanges are located on the inner side and the outer side of the sliding cover correspondingly; the spring is arranged between the flange on the inner side of the sliding cover and the sliding cover, and two vertical sliding chutes which are distributed in parallel and at intervals are formed in the sliding plate; and two bulges matched with the two sliding chutes are arranged on the inner side of the sliding cover. The structural design is reasonable, pre-treatment is conducted on the fixing pin which is a vulnerable part, so that the mechanical strength and the anti-wear property of the fixing pin are improved, accordingly the vulnerable part does not need to be replaced regularly in the up-down adjusting process of the headrest assembly, and meanwhile, the safety property of the child car seat is improved.

[0029] Example 1

[0030] See Figure 1 to Figure 4 , The present invention provides a child car seat, comprising: a base 1, a backrest connected to the base 1, two first siderests 3 separately arranged on both sides of the base 1, and a backrest 2 separately arranged on the backrest 2. Two second siderests 4 on both sides, a headrest 5 arranged on the backrest 2 that can slide along the backrest 2, and a headrest arranged in the backrest 2 and connected to the headrest 5 Sliding device 6, flexible protective pads 7 provided on both sides of the headrest 5;

[0031] The headrest sliding device 6 includes a sliding plate 10, a sliding sleeve 11 sleeved on the sliding plate 10, a fixed pin 12 provided on the sliding sleeve 11, and a fixed pin 12 sleeved on the fixed pin 12 The spring 13;

[0032] The sliding plate 10 is provided with a plurality of insertion holes 14 arranged in a vertical direction to cooperate with the fixing pin 12, and the fixing pin 12 includes: a pin 15 and a space provided on the pin 15 The two flanges 16 are arranged, the fixing pin 12 is inserted into the sliding sleeve 11, and the two flanges 16 are respectively located on the inner and outer sides of the sliding sleeve 11, and the spring 13 is provided on the sliding sleeve 11 Between the flange 16 on the inner side of the sleeve 11 and the sliding sleeve 11, the sliding plate 10 is provided with two parallel and spaced vertical sliding grooves 17, and the inner side of the sliding sleeve 11 is provided with the two Two protrusions 18 matched with a sliding groove 17.

[0033] Specifically, the child car seat can be fixed in the car through a car seat belt, or can be fixed in the car through an ISOFIX interface. Correspondingly, the child car seat also includes: an ISOFIX interface connected to the base, Two first safety belt holes 8 provided on the backrest 2 and two second safety belt holes 9 provided on the two first side supports 3 separately.

[0034] Specifically, the child car seat can pull out the fixing pin 12 so that the headrest slides along the chute 17 and then disassemble the fixing pin 12 to adjust the height of the headrest by the headrest sliding device, which is reinforced by a flexible protective pad Safe protection of children's heads.

[0035] Example 2

[0036] A manufacturing process for the headrest of a child car seat, the steps are as follows:

[0037] ①, structure and forming

[0038] The headrest assembly is placed on the backrest and can slide along the backrest. The backrest is provided with a headrest sliding device connected to the headrest; the headrest sliding device includes a sliding plate, a sliding sleeve sleeved on the sliding plate, and The fixed pin on the sliding sleeve and the spring sleeved on the fixed pin; the sliding plate is provided with a plurality of sockets arranged in a vertical direction to cooperate with the fixed pin; the fixed pin includes a pin rod, which is arranged on the pin rod The two flanges are arranged at intervals, the fixing pin is inserted into the sliding sleeve, and the two flanges are respectively located on the inner and outer sides of the sliding sleeve. The spring is arranged between the flange on the inner side of the sliding sleeve and the sliding sleeve. The sliding plate is provided with Two vertical sliding grooves arranged in parallel and spaced apart, two protrusions matching the two sliding grooves are provided on the inner side of the sliding sleeve;

[0039] The components other than the fixed pin are prepared by using existing technology;

[0040] The material of the fixed pin is carbon steel, and the processing technology is forging and forming;

[0041] ②, fixed pin pretreatment

[0042] Soak the fixed pin in the pretreatment solution for 5 hours, and directly put it in the heat treatment furnace for heat treatment at 300°C for 1 hour after taking it out;

[0043] The pretreatment liquid is composed of 15 parts of butyl acrylate, 4 parts of stearic acid, 5 parts of nano-silica, 15 parts of diluent, 5 parts of antifoaming agent, 3 parts of accelerator, 15 parts of methanol, 7 parts of Bispyrifen, 4 parts of cineole are prepared by reacting in a reactor at 85°C for 1 hour;

[0044] ③, assembly

[0045] Assemble in sequence according to the structural relationship shown in step ①.
