[0002] The seat belts in cars are designed according to adult standards and are suitable for adults weighing 36kg and over 140cm in height. If used by children, the seat belts will get stuck on the children's necks, which will be more harmful to children in the event of an accident. Therefore, child seats are specially designed. Child seats are seats used exclusively for children in cars. They are generally installed in passenger cars and fixed to the back seats to protect children's safety during driving. Correct use of child safety seats can effectively reduce the mortality rate of children in car accidents by 70%.

[0003] At present, child seats are usually installed on top of regular adult seats in cars. This solution will take up a lot of space on the one hand, and on the other hand, after the child seat is installed, the area can only be used by children, and adults can no longer use the seat, which brings a lot of inconvenience to the regular use of the car. Therefore, an integrated adult-child seat is proposed. For example, the patent with publication number CN107953809B discloses a seat assembly and a vehicle for a vehicle. For example, the patent with publication number CN220535476U discloses a car seat integrated with a child seat. Such seats are all made by embedding the child seat as a whole in the adult seat, wherein the child backrest is embedded in the adult backrest, and the child cushion is embedded in the adult cushion. When the posture is changed, the child cushion protrudes from the adult cushion, and the child backrest protrudes from the adult backrest. However, such seats have the following problems:

[0004] 1. Since it needs to be installed separately on the adult seat cushion and the adult backrest, it is easy to damage the integrity of the adult seat, thus affecting the riding comfort of the adult seat. In addition, it needs to be processed together with the adult seat during production, which makes the production process cumbersome and is not conducive to mass production.

[0005] 2. The adjustment between the backrest and the seat cushion of the child seat needs to rely on the adjustment structure of the adult seat, which easily affects the adjustment function of the adult seat and generally cannot be achieved by modifying the existing adult seat, increasing the manufacturing cost.

[0051] Regarding the drawings of the present application, it should be clearly understood that the drawings are for illustration and description purposes only and are not intended to limit the scope of the present specification. It should also be understood that the drawings are not drawn to scale.

[0052] Embodiment 1:

[0053] like Figures 1 to 8 As shown, this embodiment provides an integrated adult-child seat, which can be applied to seats of various vehicles, such as cars, ships, airplanes, etc., and will be described below using the application in car seats as an example.

[0054] The integrated seat has an adult sitting posture and a child sitting posture, wherein the child sitting posture includes a toddler sitting posture. Usually, the child sitting posture is for children aged 4-12, and the toddler sitting posture is for children under 4 years old. The toddler sitting posture requires the child backrest 2 to be moved to the opposite side of the adult backrest.

[0055] The integrated seat includes an adult seat and a child seat, wherein the adult seat includes an adult seat cushion and an adult backrest, and the child seat includes a child seat cushion 1 and a child backrest 2; wherein the adult seat and the child seat generally also include a headrest, a safety belt and the structure that a conventional car seat should have.

[0056] The child seat has a folding posture and a sitting posture through a first conversion mechanism; usually, in the folding posture, the child seat cushion 1 and the child backrest 2 are arranged in parallel, so that it is convenient to be stored in the adult seat, and in the sitting posture, the angle between the child seat cushion 1 and the child backrest 2 is greater than 90°, thus providing the child seat with a better riding comfort.

[0057] Specifically, the first conversion mechanism 4 is used to adjust the folding angle of the child seat cushion 1 and the child backrest 2, and the range of the folding angle is not less than 90°. In this embodiment, the range of the folding angle is 0°-110°, where 0° corresponds to the folding posture and 100° corresponds to the sitting posture.

[0058] When the integrated seat is in an adult sitting position, the child seat is in a folded position and embedded in the adult seat cushion or adult backrest; generally, an installation groove of suitable size is provided on the adult seat cushion or adult backrest, and the child seat in a folded position is embedded therein, and the child seat does not exceed the body-contacting surface of the adult seat cushion or adult backrest. Preferably, when the child seat is in a folded position, the back side of the child backrest 2 constitutes a part of the body-contacting surface of the adult seat cushion, or the back side of the child seat cushion 1 constitutes a part of the body-contacting surface of the adult backrest, so that the back side of the child backrest 2 or the back side of the child seat cushion 1 needs to be set corresponding to the body-contacting surface of the adult seat cushion or adult backrest, for example, a cushion layer of genuine leather, artificial leather, microfiber leather, etc.

[0059] Through the above arrangement, the child seat is embedded in the adult seat cushion or adult backrest, which reduces damage to the integrity of the adult seat and improves the riding comfort of the adult seat. At the same time, during production, the adult seat and the child seat can be separated into two modules for simultaneous processing and finally assembled together, which improves production efficiency and is conducive to mass production.

[0060] Secondly, there is little functional interference between the adult seat and the child seat. For example, the child seat can independently adjust the angles of the child seat cushion 1 and the child backrest 2 without relying on the adult seat, which is conducive to the inspection and maintenance of the product.

[0061] The present application provides a specific structure of an integrated seat, including a connecting frame 30, a first functional frame 31 and a second functional frame 32; wherein the connecting frame 30 can be used as a part of an adult seat or a part of a child seat. In the present embodiment, the connecting frame 30 is used as a part of the child seat. In this way, if one of the adult seat and the child seat fails, they can be replaced separately, thereby reducing the use cost of the product. At the same time, it is easier to modify the existing adult seat, for example, a groove of a certain size is opened on the existing adult seat to install the child seat.

[0062] When the connecting frame 30 is connected to an adult seat cushion, the first functional frame 31 serves as a child seat cushion 1 and the second functional frame 32 serves as a child backrest 2 ; when the connecting frame 30 is connected to an adult backrest, the first functional frame 31 serves as a child backrest 2 and the second functional frame 32 serves as a child seat cushion 1 .

[0063] It should be understood that there are various structures that can achieve folding angle adjustment between the child seat cushion 1 and the child backrest 2, and reference can be made to the corresponding structures in the field of automobile seats in the prior art. In the present embodiment, a first conversion mechanism 4 is provided, wherein the first functional frame 31 is hinged to one side of the second functional frame 32, and the first conversion mechanism 4 includes a first actuator 40, a first gear 41 and a first sector-shaped toothed disc 42, wherein the first gear 41 is connected to the first actuator 40, and the first sector-shaped toothed disc 42 includes a first sector-shaped tooth portion 421, wherein the first gear 41 is meshed with the first sector-shaped tooth portion 421, and the first actuator 40 is arranged on the second functional frame 32, and the first sector-shaped toothed disc 42 is arranged on the first functional frame 31, and the first actuator 40 drives the first gear 41 to rotate around the first sector-shaped tooth portion 421 so that the second functional frame 32 rotates a certain angle relative to the first functional frame 31, and the angle adjustment is achieved through gear matching, which has good stability and controllability.

[0064] When the integrated seat is in a child sitting posture, the child seat is in a sitting posture, and the second conversion mechanism is used to make the body-contacting surface of the child seat protrude beyond the body-contacting surface of the adult seat; the body-contacting surface is the side that contacts the human body when a person sits, wherein the second conversion mechanism is realized by a second conversion mechanism 5, and the second conversion mechanism 5 is used to adjust the distance between the child seat cushion 1 and the adult seat cushion or the distance between the child backrest 2 and the adult backrest, so that the body-contacting surface of the child seat cushion 1 protrudes beyond the body-contacting surface of the adult seat cushion, or the body-contacting surface of the child backrest 2 protrudes beyond the body-contacting surface of the adult backrest.

[0065] It should be understood that the conversion mechanism can be a rotating mechanism, a folding mechanism, a lifting mechanism, etc., and is not limited to one of them. However, in order to simplify the conversion process, it is preferred to use a mechanism with one form of motion to achieve the desired effect. For example, the first conversion mechanism uses a folding mechanism, and the second conversion mechanism uses a lifting mechanism.

[0066] It should be understood that there are many structures that can adjust the distance between the child seat cushion 1 and the adult seat cushion or the distance between the child backrest 2 and the adult backrest. The corresponding structures in the field of automobile seats in the prior art can be referred to. For example, a cylinder is directly used to adjust the distance, or a motor is used to adjust the distance in conjunction with a screw rod and a slider structure. In this embodiment, considering the structural strength, manufacturing cost, installation space and other factors, a second conversion mechanism 5 is provided, including a second actuator 50, a first screw rod 51, a first slider 52 and a fork frame 53. The fork frame 53 includes a first rod 531 and a second rod 532 hinged in the middle. The fork frame 53 has four connecting ends 533, two of which are connected to the connecting frame 30, and the other two connecting ends 533 are connected to the first functional frame 31. The two connecting ends 533 are hingedly connected, and the other two connecting ends 533 are slidably connected. The sliding connection is to set a first sliding hole 55 on the corresponding frame, and the connecting end 533 is slidably arranged relative to the first sliding hole 55. The first sliding hole 55 can be an oblong hole.

[0067] A push rod 54 is disposed on the connection end 533 that adopts a sliding connection. The push rod 54 adopts a round shaft and is slidably disposed in the first sliding hole 55 .

[0068] Through the cooperation of the second actuator 50 , the first screw rod 51 , the first slider 52 and the push rod 54 , the fork frame 53 can be controlled to expand or contract around its hinge center, thereby adjusting the distance between the connecting frame 30 and the first functional frame 31 .

[0069] It should be understood that there are various specific settings for the second conversion mechanism 5. Preferably, the second actuator 50 is arranged on the connecting frame 30, so that the second actuator 50 is away from the child seat 1, reducing the impact of the second actuator 50 on the child seat 1 when it is in operation. There are two fork frames 53 and they are respectively arranged on two opposite sides of the connecting frame 30 and the first functional frame 31. The two fork frames 53 improve the bearing capacity of the first functional frame 31 as a child seat 1. The two connecting ends 533 of the fork frame 53 connected to the connecting frame 30 are connected by sliding, and the two connecting ends 533 connected to the first functional frame 31 are connected by hinged connection, so that the first functional frame 31 can be raised and lowered along a straight line to reduce the occupied space in the adult seat. The push rod 54 is arranged between the connecting ends 533 of the two fork frames 53 corresponding to the sliding connection. The second actuator 50 is driven in the middle of the first screw rod 51, and the first slider 52 is arranged at both ends of the first screw rod 51 corresponding to the push rod 54. The two first sliders 52 move in opposite directions at the same time, driving the corresponding push rods 54 to move, so that the two connection ends 533 on the lower side of the fork frame 53 are close to or away from each other, thereby adjusting the distance between the first functional frame 31 and the connecting frame 30. There are many connection structures between the first slider 52 and the push rod 54, such as a slot provided on the first slider 52, the push rod 54 is embedded in the slot, or they are connected by a connecting piece.

[0070] Regarding other configurations of the second conversion mechanism 5, for example, the second actuator 50, the first screw rod 51, the first slider 52 and the push rod 54 can also be arranged on the first functional frame 31. For example, any two of the connecting ends 533 of the fork frame 53 that are slidably connected can be selected.

[0071] The first conversion mechanism and the second conversion mechanism are used to realize the conversion of the integrated seat between the adult sitting posture and the child sitting posture. The first conversion mechanism and the second conversion mechanism are converted simultaneously, or one is converted first and the other is converted later, which can be set according to the actual scene.

[0072] Furthermore, in order to improve the comfort of the child seat, the child seat also includes a child headrest 6, and the child headrest 6 has an extended posture and a retracted posture through a third conversion mechanism; when the child seat is in a folded posture, the child headrest 6 is retracted in the child backrest 2; when the child seat is in a sitting posture, the child headrest 6 at least partially extends out of the child backrest 2.

[0073] The third conversion mechanism can adopt a telescopic mechanism, and the child headrest 6 is slidably set on the first functional frame 31 or the second functional frame 32. The third conversion mechanism 7 includes a third actuator 70, a second screw rod 71 and a second slider 72. The second slider 72 is connected to the child headrest 6. The third actuator 70 drives the second screw rod 71 to rotate, and the second slider 72 translates on the second screw rod 71, driving the child headrest 6 to extend out of the corresponding functional frame or retract into the corresponding functional frame.

[0074] Secondly, the child headrest 6 is slidably arranged on the second functional frame 32, and the second functional frame 32 includes two first side panels 321 and a first bottom panel 322, and the two first side panels 321 are vertically arranged on both sides of the first bottom panel 322, and the first side panel 321 is provided with a second sliding hole 73, and the second sliding hole 73 is an oblong hole, and the first bottom panel 322 is provided with a third sliding hole 74, and the third sliding hole 74 is an oblong hole; the child headrest 6 includes two second side panels 61 and a second bottom panel 62, and a connecting plate 63 is vertically arranged on the side of the second bottom panel 62 away from the second functional frame 32, and the two second side panels 61 Vertically arranged on both sides of the connecting plate 63 and arranged toward the second functional frame 32, a sliding shaft 64 is arranged on one side of the two second side plates 61 close to the third actuator 70, and the two ends of the sliding shaft 64 are respectively slidably arranged in the two second sliding holes 73, the two second side plates 61 are located on the inner sides of the two first side plates 321, and the second bottom plate 62 is located on the outer side of the first bottom plate 322, so that the child headrest 6 and the second functional frame 32 form a plug-in structure, so that the child headrest 6 is more stable during the translation process, and at the same time, the second bottom plate 62 serves as the working surface of the child headrest 6, and its bearing capacity can be enhanced with the help of the first bottom plate 322.

[0075] The second bottom plate 62 is provided with a fourth sliding hole 75 matched with the third sliding hole 74, and the third sliding hole 74 and the fourth sliding hole 75 are provided with connecting columns 76. In the present embodiment, the third sliding hole 74 and the fourth sliding hole 75 are of the same size, and there are two of each, and they are symmetrically arranged at intervals, so as to further improve the stability of the child headrest 6 during the extension and retraction process.

[0076] Through the above arrangement, the third actuator 70 drives the second screw rod 71 to rotate, and the second slider 72 translates on the second screw rod 71, driving the child headrest 6 to extend out of the corresponding functional frame or retract into the corresponding functional frame, so that the auxiliary seat has a headrest function, thereby improving its riding comfort.

[0077] The third conversion mechanism can also adopt a flipping mechanism. One side of the child headrest 6 is hinged to the first functional frame 31 or the second functional frame 32. The third conversion mechanism 7 includes a fourth actuator, which directly drives the child headrest 6 to rotate relative to the first functional frame 31 or the second functional frame 32 through the fourth actuator, or indirectly drives it through a gear set. Those skilled in the art should be able to understand.

[0078] Furthermore, when the child seat cushion 1 is connected to the adult seat cushion through the connecting frame 30, the first functional frame 31 serves as the child seat cushion 1, and the second functional frame 32 serves as the child backrest 2; at this time, the connecting frame 30 is rotated and set in the adult seat cushion, and the child backrest 2 can be rotated to the opposite side of the adult backrest through a rotating mechanism to form the sitting posture of the young child, thereby improving the practicality and applicability of the integrated seat.

[0079] Among them, the rotating mechanism can use a fifth actuator in conjunction with a gear set. For example, an outer ring gear or an inner ring gear is set on the connecting frame 30, and the gear connected to the fifth actuator is meshed with the outer ring gear or the inner ring gear to realize the rotation of the child seat. Through this arrangement, when the adult sitting posture is converted to the child sitting posture, the child seat does not need to be fully extended from the adult seat cushion first, and can be rotated after partially extending the adult seat cushion, thereby shortening the posture conversion time. Among them, the connecting frame 30 is preferably set to a disc shape.

[0080] Furthermore, the integrated seat also includes a seating board;

[0081] In normal use, the riding board is arranged on the back of the child backrest 2 or the back of the child seat cushion 1 and moves synchronously therewith. When the integrated seat is in an adult sitting posture, the riding board constitutes a part of the body-contacting surface of the adult seat cushion or a part of the body-contacting surface of the adult backrest;

[0082] When the child seat is removed, the riding board is connected to the adult seat cushion and constitutes a part of the body-contacting surface of the adult seat cushion, or the riding board is connected to the adult backrest and constitutes a part of the body-contacting surface of the adult backrest. For example, when the child seat fails, the child seat can be removed separately for repair, and at the same time, by removing the riding board from the child seat and connecting it to the adult seat, the adult seat can be used normally without the need to keep the car in the repair shop for a long time.

[0083] Specifically, taking the example of a child seat embedded in an adult seat cushion, the adult seat cushion is provided with an installation groove for the folded child seat to be embedded, and the sitting board is detachably connected to the back of the child backrest 2, such as bolt connection, snap connection, bonding, etc., and the area of ​​the sitting board is larger than the area of ​​the back of the child backrest 2, for example, the sitting board is provided with a connecting lug, or is expanded along its outer contour, and the open end of the installation groove is provided with a groove portion for the sitting board to be embedded, and a detachable connection structure, such as a bolt connection, or a locking structure, such as a latch, is provided between the sitting board and the groove portion; in normal use, no connection is formed between the sitting board and the groove portion, and under the action of the first conversion mechanism 4, the sitting board moves with the child backrest 2, and when the child seat is removed, the sitting board is removed from the child backrest 2, and the sitting board is connected to the groove portion for sitting.

[0084] Furthermore, each mechanism, such as the first conversion mechanism, the second conversion mechanism, the third conversion mechanism, and the rotating mechanism, can be driven manually or by an actuator. It should be understood that as for driving one mechanism at a time, or driving multiple mechanisms at a time, those skilled in the art can achieve this by adjusting the transmission structure.

[0085] Preferably, each mechanism is driven by an actuator, and the actuator is preferably a motor. The actuator is connected to the control system and power supply system on the vehicle. This seat is particularly suitable for the field of new energy vehicles and can further enhance the intelligence level of new energy vehicles, for example, in conjunction with voice control, visual detection and other functions, which will not be described in detail here.

[0086] In addition, the child seat provided in this embodiment has a simple structure and can meet the riding needs of children. At the same time, without changing its structure, it only needs to change the position where it is installed on the adult seat to achieve the seat cushion or backrest embedded in the adult seat. These two forms of child seats have better adjustability and flexibility, and can adapt to most adult seats and adapt to more installation scenarios.

[0087] Embodiment 2:

[0088] like Figures 9 to 11As shown, this embodiment provides another second conversion mechanism 5. Specifically, the second conversion mechanism 5 includes a sixth actuator 500, a transmission screw 501, a transmission seat 502, a swing seat 503, a transmission shaft 504, a first swing rod 505 and a second swing rod 506. The sixth actuator 500 is arranged on the connecting frame 30. The sixth actuator 500 is connected to the middle of the transmission screw 501 and drives the transmission screw 501 to rotate. The transmission seat 502 is two and is respectively arranged at both ends of the transmission screw 501. One end of the swing seat 503 is hinged to the transmission seat 502, and the other end is connected to the transmission shaft 504. The transmission shaft 5 04 is rotatably arranged on the connecting frame 30, and both ends are connected to the first swing rod 505. One end of the second swing rod 506 is hinged to the first swing rod 505, and the other end is hinged to the child seat 1. When the sixth actuator 500 drives the transmission screw 501 to rotate, the transmission seats 502 on both sides move along the direction of the transmission screw 501, driving the swing seat 503 to rotate, and driving the transmission shaft 504 to rotate, and driving the first swing rod 505 to rotate, and driving the second swing rod 506 to rotate, so that the angle between the first swing rod 505 and the second swing rod 506 can be adjusted, thereby adjusting the distance between the child seat 1 and the connecting frame 30. Among them, the first swing rod 505 and the second swing rod 506 are four groups to ensure the stability of the child seat 1 when it is raised or lowered. By adopting this second conversion mechanism 5, the range of the adjustable distance between the child seat 1 and the connecting frame 30 can be increased in a limited space.
