[0001] The present disclosure relates to the technical field of safety seats, and in particular to a base and a safety seat. Background Art

[0002] A child seat, also known as a child restraint system, is a seat designed for children of different ages (or weights), installed in a car, and can effectively improve the safety of children riding in a car. The European regulation ECE R129 defines a child safety seat as: a child safety protection system that can be fixed to a motor vehicle and consists of a seat belt assembly or flexible components, adjustment mechanisms, accessories, etc. It can be combined with additional devices such as a portable crib, infant carrier, auxiliary seat or collision protection device. It can reduce the impact force on children and limit their body movement in the event of a car collision or sudden deceleration to reduce injuries to them, ensuring the safety of children riding in a car. It is widely used.

[0003] In order to meet the safety needs of children of different ages, many existing child car safety seats can be rotated and adjusted, and the seat body can rotate 360 ​​degrees relative to the base. For example, the utility model patent with patent number 202122621263.2 discloses a connecting mechanism and a child safety seat. The connecting mechanism includes a guide rail with a circular ring-shaped integral structure, a turntable and an annular stepped mounting seat. The guide rail is fixed on the mounting seat, and the guide rail portion is suspended on the guide rail. A bracket assembly is installed on the turntable. The bracket assembly is stuck on the suspended portion of the guide rail, and the bracket assembly can rotate around the guide rail. In the utility model, the bracket assembly is provided with a U-shaped mounting port, and the guide rail portion is embedded in the mounting port. However, during the rotation of the bracket assembly around the guide rail, the mounting port is subjected to greater force. The mounting port of the utility model is directly opened on the first bracket and the second bracket, and the strength is not high. Utility Model Content

[0037] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the present disclosure is described in detail, clearly and completely in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not used to limit the present disclosure.

[0038] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0039] Please see Figure 3 to Figure 6 , Figure 8 As shown, an embodiment of the present disclosure provides a base, including a shell and a bracket assembly 6, a guide rail 5 is arranged on the shell, and the bracket assembly 6 can rotate along the guide rail 5. The bracket assembly 6 includes a first bracket 7 and a second bracket 8, both ends of the first bracket 7 and the second bracket 8 are provided with openings, and all the openings are connected with a reinforcement 9, the reinforcement 9 and the first bracket 7 form a first installation opening, the reinforcement 9 and the second bracket 8 form a second installation opening, and the guide rail 5 is installed in the first installation opening and the second installation opening. The bottom of the first bracket 7 and the bottom of the second bracket 8 are both provided with working holes, and bolts pass through the working holes to connect the reinforcement 9 with the first bracket 7 and the second bracket 8. In order to enhance the structural stability and load-bearing capacity of the base, the guide rail 5 and the bracket assembly 6 are both made of metal, the reinforcement 9 is a long strip plate structure, and is also set to metal material, the reinforcement 9 is arranged at the bottom of the first bracket 7 and the second bracket 8, and forms a U-shaped first installation opening and a second installation opening with the upper part of the opening, so as to facilitate the embedding of the guide rail 5. Compared with the prior art in which mounting openings are directly opened on the first bracket 7 and the second bracket 8, the arrangement in which the reinforcement member 9 and the first bracket 7 form a first mounting opening, and the reinforcement member 9 and the second bracket 8 form a second mounting opening makes the strength of the first mounting opening and the second mounting opening greater, thereby making the base have a longer service life; the guide rail 5 is installed in the first mounting opening and the second mounting opening, which can not only meet the normal installation of the guide rail 5, but also enhance the overall structural strength of the base.

[0040] Please also see Figure 7As shown, the opening includes a front opening 12 and a rear opening 11, the front opening 12 is close to the child's legs, and the rear opening 11 is close to the child's buttocks. After the child seat is set on the vehicle seat, the normal direction of the child seat is the driving direction of the car. When the car brakes during driving, the child sitting on the seat will fall forward or have a tendency to fall forward due to inertia. At this time, the reinforcement 9 located at the rear opening 11 will be subjected to an oblique upward drag force. In order to resist or weaken the impact of this drag force on the first mounting opening and the second mounting opening located at the rear, two reinforcements 9 are set at the rear opening 11 to strengthen the structural strength and stability here and reduce a series of unsafe factors caused by drag. In particular, in order to better balance the force, the two reinforcements 9 at the rear opening 11 are located on both sides of the first bracket 7 or the second bracket 8, so that the first bracket 7 or the second bracket 8 is between the two reinforcements 9. Since the front opening 12 is almost not subject to a large degree of drag, the reinforcement 9 at the front opening 12 can be set one or two, without specific restrictions. When two reinforcement members 9 are provided at the front opening 12, the two reinforcement members 9 are located on both sides of the first bracket 7 or the second bracket 8. When one reinforcement member 9 is provided at the front opening 12, the reinforcement member 9 is provided on the outside of the first bracket 7 or the second bracket 8, which is convenient for installation and maintenance.

[0041] Further, the first mounting opening and the second mounting opening are both provided with a first anti-wear sleeve 10, and the first anti-wear sleeve 10 is provided with a contact surface, and the contact surface contacts the guide rail 5. The provision of the first anti-wear sleeve 10 avoids direct contact between the guide rail 5 and the bracket assembly 6, and reduces the wear between the two. Preferably, the first anti-wear sleeve 10 is made of plastic material, and the plastic plays a lubricating role, and the plastic can be deformed to a certain extent, so that the bracket assembly 6 is smoother when rotating along the guide rail 5.

[0042] Please also see Fig. 9As shown, in one embodiment of the present disclosure, the first anti-wear sleeve 10 is provided with a snap-in point, and the snap-in point is snapped into the first mounting port or the second mounting port. Specifically, the snap-in point includes a first snap-in point and a second snap-in point. After the first anti-wear sleeve 10 is connected to the first bracket 7, the first bracket 7 is snapped into the first snap-in point, and the reinforcement 9 is snapped into the second snap-in point; after the first anti-wear sleeve 10 is connected to the second bracket 8, the second bracket 8 is snapped into the first snap-in point, and the reinforcement 9 is snapped into the second snap-in point. The first snap-in point and the second snap-in point are provided to strengthen the connection between the first anti-wear sleeve 10 and the bracket assembly 6 and the reinforcement 9, thereby strengthening the structural stability of the base. A support frame 15 is also provided on the first anti-wear sleeve 10, and the upper end of the support frame 15 contacts the upper end of the opening, thereby playing a supporting role. Due to the setting of the support frame 15, there is a gap between the reinforcement 9 and the upper surface of the second clamping point. The gap acts as a buffer, so that the bracket assembly 6 has more space margin when rotating along the guide rail 5, thereby making the bracket assembly 6 smoother when rotating along the guide rail 5 and avoiding jamming.

[0043] like Figure 1 and Figure 2 As shown, the shell includes a first shell 1 and a second shell 2 that are clamped together, a guide rail 5 is arranged on the first shell 1, and a cover plate 3 is arranged on the first shell 1.

[0045] Furthermore, two pressure plates are arranged between the cover plate 3 and the guide rail 5, namely a front pressure plate and a rear pressure plate. The front pressure plate and the rear pressure plate are respectively arranged at the front and rear positions of the bottom of the seat. Since babies (or children) often lean back or forward when using the seat, the front and rear positions of the bottom of the seat and the corresponding positions of the guide rail 5 are subject to great load-bearing and wear. Therefore, in order to enhance the strength of this location, two pressure plates are arranged between the cover plate 3 and the guide rail 5.

[0046] In another embodiment, the front opening 12 is a C-shaped opening, that is, the front opening 12 is a first installation opening; the rear opening 11 is an L-shaped opening, and the reinforcement 9 is only arranged at the rear opening 11. The reinforcement 9 and the rear opening 11 form a second installation opening, and there are two reinforcements 9 to increase the impact resistance during impact. The reinforcement 9 can also be added to the lower part of the front opening 12 that is a C-shaped opening as needed.

[0047] In another embodiment, the front opening 12 is a C-shaped opening, that is, the front opening 12 is the first installation opening; the rear opening 11 is also a C-shaped opening, and the reinforcing member 9 is only arranged at the lower part of the C-shaped opening at the rear opening 11, so as to strengthen the lower part of the C-shaped opening and increase the impact resistance during impact.
