Description

Technical Field

[0001] This invention belongs to the field of automotive seat technology, specifically relating to an integrated child seat. Background Technology

[0002] Currently, most car seats are standard car seats designed for adults. The size, shape, and posture of the seat cushion and backrest are designed to suit adults and cannot meet the needs of children. Therefore, children need to use child safety seats when riding in a car.

[0003] There are two types of child seats on the market: independent and integrated. Independent child seats are individual child seats installed at the original fixing point in the car, which is then fixed to the adult seat for the purpose of child use. Integrated child seats are adult and child seats in one structure, which can switch between adult and child modes according to different usage needs, and their appearance is similar to that of conventional seats.

[0004] Independent child seats have problems such as difficulty in disassembly and installation, and large space occupation in the vehicle interior. Patent number CN111267691A discloses an integrated child seat, including a backrest and a main seat cushion. The main seat cushion has a first concave cavity with an upward opening, and the child seat is arranged in the first concave cavity. The child seat includes a folding mechanism, a child seat cushion, a button, a motor, and a top rod. The folding mechanism is located in the first concave cavity and its upper end is connected to the child seat cushion. When in use, the folding mechanism is driven by the motor to fold up or down to raise or lower the child seat cushion. This technical solution does not require repeated disassembly and installation and can save vehicle interior space, but it still has the following problems: the folding mechanism adopts a four-bar structure, and the child seat cushion is mainly supported by the top rod after it is raised, which has poor load-bearing capacity and stability, making it difficult to ensure the safety of children riding in the car. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated child seat to solve the technical problems of poor load-bearing capacity and stability of existing integrated child seats.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] An integrated child seat includes a backrest, a base, and a seat cushion lifting mechanism. The backrest is located at one end of the base. The base has an installation groove. The seat cushion lifting mechanism includes a child seat cushion, a transmission assembly, and a positioning assembly. The transmission assembly is used to drive the child seat cushion to rise away from the installation groove or descend into the installation groove. The transmission assembly includes two long support arms, a first rotating shaft, a short support arm, a second rotating shaft, and two mounting rods. One end of each of the two long support arms is rotatably installed in the installation groove, and the other end of each long support arm is rotatably connected to both ends of the first rotating shaft. The two ends of the short support arm are fixed to the first and second rotating shafts, respectively. The two ends of the second rotating shaft are rotatably connected to the two mounting rods, and the child seat cushion is fitted onto the two mounting rods. The positioning assembly is used to open or lock the transmission assembly and also to fix the child seat cushion in the installation groove or on the backrest.

[0008] The technical principle of this solution is as follows:

[0009] When switching from an adult seat to a child seat, the positioning component opens the transmission assembly. Then, pull the child seat cushion diagonally upwards to slide it out of the mounting slot. Next, lift the child seat cushion upwards, and finally push it backwards. The positioning component secures the two mounting rods to the backrest, fixing the child seat cushion in place and locking the transmission assembly. During the switching process, the transmission assembly moves as follows: the two mounting rods move diagonally upwards with the child seat cushion, driving the second rotating shaft to rotate. The second rotating shaft, through a short support arm, drives the first rotating shaft to rotate until the child seat cushion moves forward and upward out of the mounting slot. Lifting the child seat cushion upwards, the two mounting rods move upwards with it, and the two long support arms rotate upwards with the mounting rods until the child seat cushion reaches its highest point. Finally, pushing the child seat backwards moves the two mounting rods backwards with it, driving the second rotating shaft to rotate. The second rotating shaft, through the short support arm, drives the first rotating shaft to rotate until the positioning component secures the two mounting rods to the backrest and locks the transmission assembly. When switching from a child car seat to an adult car seat, the switching steps and process are the reverse of those when switching to a child car seat.

[0010] The beneficial technical effects of this solution are as follows:

[0011] 1. After switching to a child seat, the child seat cushion is supported by two long support arms and a short support arm. The child seat cushion is fixed to the backrest by the positioning component. After the seat position is switched, the transmission component is locked by the positioning component to prevent the child seat cushion from shifting during the journey. Compared with the four-bar transmission mechanism and top rod support method used in existing integrated child seats, the present invention has better load-bearing capacity and stability, and can better protect the safety of children in the car.

[0012] 2. The seat lifting mechanism of the present invention does not require a motor or hydraulic drive to lift the child seat, and its simple structure can save manufacturing costs.

[0013] 3. The present invention has a simple and lightweight structure, enabling quick and free switching between adult and child seats. It is also simple to operate and easy to use. Compared with traditional independent child seats, the present invention has a greater advantage in production cost.

[0014] Furthermore, the positioning component includes a pull strap and a first locking element. The first locking element includes a first pin, a locking hook, and a first torsion spring. The first pin is fixed to a mounting rod. The locking hook is rotatably connected to the first pin. The first torsion spring is sleeved on the first pin, and its two ends are respectively connected to the mounting rod and the locking hook. One end of the pull strap is fixed to the locking hook, and the other end of the pull strap passes through the child seat cushion. A locking pin is fixed on the short support arm, and the free end of the locking hook can hook onto the locking pin.

[0015] Beneficial effects: When the free end of the locking hook engages with the locking pin, neither the first nor the second pivot can rotate. When switching seat positions, the locking hook is rotated by pulling the strap, causing it to disengage from the locking pin, allowing the first and second pivots to rotate. After the seat position is switched, the strap is released, and the locking hook re-engages with the locking pin under the torque of the first torsion spring. By incorporating the first locking element, the rotation of the first and second pivots is restricted, enhancing the stability of the child seat cushion.

[0016] Furthermore, the positioning assembly also includes a first limiting rod, a second limiting rod, and a second locking member, with two of each of the first limiting rod, second limiting rod, and second locking member; both first limiting rods are fixed in the mounting groove; both second limiting rods are fixed to the backrest; the two second locking members have the same structure and are respectively located on two mounting rods; each of the two second locking members includes a second pin, a locking tongue, and a second torsion spring; the second pin is fixedly mounted on the mounting rod, the locking tongue has a limiting groove and is rotatably mounted on the second pin, and the second torsion spring is loosely fitted on the second pin, with its two ends connected to the mounting rod and the locking tongue respectively; a pull cable is provided between the first locking member and the two second locking members, and the pull cable can drive the two locking tongues to rotate; the limiting groove can lock the first limiting rod and the second limiting rod.

[0017] Beneficial effects: In the adult seat position, the two first limiting rods engage with the limiting grooves of the two locking tongues, securing the child seat cushion within the mounting groove. To switch positions, pull the strap, causing the locking hook to rotate. The hook, via a cable, rotates the two locking tongues. Then, pull the child seat cushion diagonally upwards, disengaging the limiting grooves of the two locking tongues from the first limiting rods. Next, lift the child seat cushion upwards and push it backwards, engaging the limiting grooves of the two locking tongues with the second limiting rods. Release the strap, and the two locking tongues return to their original position under the torque of the second torsion spring, with the limiting grooves facing downwards, locking the two second limiting rods within their respective grooves, thus securing the child seat cushion to the backrest. To switch positions again, simply pull the strap. By incorporating a second locking element to restrict the position of the child seat cushion, its stability and load-bearing capacity are improved.

[0018] Furthermore, each of the two second locking components also includes a third pin, a lock top, and a third torsion spring. The third pin is fixedly mounted on the mounting rod, and the lock top is rotatably mounted on the third pin, with the lock top abutting against the lock tongue. The third torsion spring is loosely fitted on the third pin, and its two ends are respectively connected to the mounting rod and the lock top. The cable is Y-shaped, with one end fixedly mounted on the lock hook, and the other two ends hinged to the two lock tops respectively.

[0019] Beneficial effects: By pulling the cable to rotate the lock top, the lock top drives the lock tongue to rotate, thereby changing the orientation of the lock tongue's limiting groove. By setting a third torsion spring, the lock top can be reset under the action of the third torsion spring after the pull strap is released. The lock top and lock tongue work together to fix the child seat in the mounting groove or on the backrest, further improving the stability of the seat.

[0020] Furthermore, a first connecting rod is fixed between the two long support arms, and the first rotating shaft is sleeved on the first connecting rod; a second connecting rod is fixed between the two mounting rods, and the second rotating shaft is sleeved on the second connecting rod.

[0021] Beneficial effects: By setting a first connecting rod to connect two long support arms and setting two second connecting rods to connect two mounting rods, the two mounting rods and two long support arms can rotate synchronously during the switching of seat states, thereby improving the stability and load-bearing capacity of the seat.

[0022] Furthermore, there are two short support arms; a reinforcing tube is fixed between the two mounting rods.

[0023] Beneficial effects: By setting up reinforcing tubes to support the two mounting rods and setting up two short support arms, the load-bearing capacity of the child seat cushion can be improved.

[0024] Furthermore, it also includes a child headrest, which includes two side panels that are rotatably mounted on both sides of the backrest. The two side panels can rotate towards each other, and the rotation angle between the two side panels and the backrest is adjustable.

[0025] Beneficial effects: By setting up child headrests, children's heads are protected, improving their safety while traveling in vehicles.

[0026] Furthermore, it also includes child armrests, which consist of two armrest panels that are rotatably mounted on both sides of the backrest.

[0027] Beneficial effects: By setting up child handrails, the area in which children can move can be restricted, improving the safety of children riding in a car, without unduly restricting their movement, thus improving the comfort of children riding in a car.

[0028] Furthermore, it also includes a five-point safety harness, which is used to protect the child's shoulders, waist and hips. The five-point safety harness includes an adjustment strap, which is used to adjust the spacing of the safety harness located at the child's shoulders according to the child's shoulder width.

[0029] Beneficial effects: The five-point harness protects children's shoulders, waist, and hips, preventing them from slipping or falling off the seat and ensuring their safety while traveling. The harness is adjustable to fit the child's shoulder width, preventing both overly loose harnesses that reduce safety and overly tight harnesses that cause discomfort. Since different children require different harnesses, the five-point harness provided in this solution can be switched to a three-point harness, effectively improving the comfort and practicality of the child seat.

[0030] Furthermore, the top of the backrest is equipped with a music headrest, and the mounting slot is equipped with a child seat footrest.

[0031] Beneficial effects: The music headrest can play music, improving the comfort of adults while riding in the car. It can also play soothing music to reduce noise from children while riding in the car. The addition of a child seat footrest can further improve the comfort of children while riding in the car.

[0050] Examples, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown,

[0051] An integrated child seat includes a backrest 1, a base 2, a seat cushion lifting mechanism, a child headrest 6, a child armrest 7, a five-point safety harness 8, and a musical headrest 9.

[0052] The backrest 1 is located at one end of the base 2, and the backrest 1 includes a backrest frame 11.

[0053] The base 2 has an installation groove 22. The base 2 includes a base frame 21. A support rod 211 is welded on the frame 21, and the support rod 211 is located at the bottom of the installation groove 22. A child seat foot pedal 23 is also provided at the bottom of the installation groove 22.

[0054] The seat lifting mechanism includes a child seat 3, a transmission component 4, and a positioning component 5.

[0055] The transmission assembly 4 is used to drive the child seat cushion 3 to rise away from the mounting groove 22 or to descend into the mounting groove 22. The transmission assembly 4 includes two long support arms 41, a first rotating shaft 42, a first connecting rod, two short support arms 43, a second rotating shaft 44, a second connecting rod, two mounting rods 45, and a reinforcing tube 46. The two long support arms 41 are symmetrically rotated and mounted on the support rod 211. The first rotating shaft 42 is a hollow round rod and is loosely fitted on the first connecting rod. The two ends of the first connecting rod are respectively threaded and fixed to the two long support arms 41. The two ends of the two short support arms 42 are respectively threaded and fixed to the two long support arms 41. The first rotating shaft 42 and the second rotating shaft 44 are welded to each other respectively; the second rotating shaft 44 is hollow round rod and is loosely fitted on the second connecting rod. The two ends of the second connecting rod are threaded to the two mounting rods 45 respectively; two long support arms 41 are located outside the two mounting rods 45, and two short support arms 43 are located between the two mounting rods 45; the two ends of the reinforcing tube 46 are welded to the two mounting rods 45 respectively; both mounting rods 45 are hollow rectangular long rods, and the end of each mounting rod 45 near the backrest has a slot; the child seat cushion 3 is fitted onto the two mounting rods 45.

[0056] The transmission component 4 is used to switch between the child seat state and the adult seat state. When switching from the adult seat state to the child seat state, the child seat cushion 3 is pulled upwards at an angle to slide out of the mounting groove 22, then the child seat cushion 3 is lifted upwards, and finally the child seat cushion 3 is pushed backwards to switch to the child seat state. During the switching process, the two mounting rods 45 move diagonally upwards along with the child seat cushion. As the two mounting rods 45 move, they drive the second rotating shaft 44 to rotate. The second rotating shaft 44, through two short support arms 43, drives the first rotating shaft 42 to rotate until the child seat cushion 3 moves forward and upward out of the mounting slot 22. The child seat cushion 3 is then lifted upwards, and the two mounting rods 45 move upwards accordingly. The two long support arms 41 also rotate towards the backrest 1 until the child seat cushion 3 reaches its highest point. Finally, the child seat cushion 3 is pushed backwards, and the two mounting rods 45 move backwards accordingly. The two mounting rods 45 drive the second rotating shaft 44 to rotate, and the second rotating shaft 44, through the short support arms 43, drives the first rotating shaft 42 to rotate until one end of the two second mounting rods 45 contacts the backrest 1. Switching from the child seat to the adult seat is the reverse of the switching steps and process, and will not be described in detail here.

[0057] The positioning component 5 includes a pull strap 51, a first locking member 52, a second locking member 53, a first limiting rod 54, and a second limiting rod 55.

[0058] The first locking component 52 includes a first pin 521, which is fixed to the side of a mounting rod 45 away from the backrest 1 by bolts. A locking hook 522 is rotatably mounted on the first pin 521, and a first torsion spring 523 is also sleeved on the first pin 521. A locking pin 431 is welded to a short support arm 43 near the first pin 521, and the free end of the locking hook 522 can hook the locking pin 431. A first positioning pin 451 is also welded to the mounting rod 45 to which the first pin 521 is fixed, and a second positioning pin is welded to the locking hook 522. The hooks at both ends of the first torsion spring 523 hook the first positioning pin 451 and the second positioning pin, respectively. One end of the pull strap 51 is fixed to the locking hook 522, and the other end of the pull strap 51 passes through the child seat cushion 3 and is located outside the child seat cushion 3.

[0059] There are two second locking components 53, and the two second locking components 53 have the same structure. The two second locking components 53 are respectively set inside the two mounting rods 45. The structure of only one second locking component 53 is described in detail below: The second locking component 53 includes a second pin 531 and a second pin 533 that are threadedly fixed to the mounting rod 45. A locking tongue 532 is rotatably mounted on the second pin 531. The locking tongue 532 has a limit groove. A locking top 534 is rotatably mounted on the third pin 533. The locking top 534 abuts against the locking tongue 532. A second torsion spring is sleeved on the second pin 531. The two ends of the second torsion spring are respectively connected to the locking tongue 532 and the mounting rod 45. A third torsion spring is sleeved on the third pin 533. The two ends of the third torsion spring are respectively connected to the locking top 534 and the mounting rod 45. A cable 535 is provided between the first locking member 52 and the two second locking members 53. The cable 535 is Y-shaped. One end of the cable 535 is fixed to the free end of the locking hook 522, and the other two ends of the cable 535 are respectively hinged to the two locking tops 534.

[0060] There are two first limiting rods 54 and two second limiting rods 55. The two first limiting rods 54 are symmetrically welded to the seat cushion frame 11 and are located in the mounting groove 22. The two second limiting rods 55 are symmetrically welded to the backrest frame 11. The first limiting rods 54 and the second limiting rods 55 can be engaged in the slots on the mounting rod 45 and the limiting grooves on the locking tongue 532.

[0061] The positioning component 5 is used to open or lock the transmission component 4, and to secure the child seat cushion 3 to the mounting slot 22 or the backrest 1. Figure 6 As shown, when the first locking member 52 is in the locked state, the free end of the locking hook 522 in the first locking member 52 hooks the locking pin 431, preventing both the first rotating shaft 42 and the second rotating shaft 44 from rotating. Figure 3 , Figure 7 As shown, when the second locking member 53 is in the locked state, the locking top 534 in the second locking member 53 abuts against the locking tongue 531, and the limiting groove of the locking tongue 531 obliquely jams the first limiting rod 54 or the second limiting rod 55, so that the two mounting rods 45 cannot move forward or backward; Figure 3 , Figure 4As shown, when the second locking member 53 is in the locked state, the first limiting rod 54 or the second limiting rod 55 is located in the slots of the two mounting rods 45, preventing the two mounting rods 45 from moving up or down. When it is necessary to switch the seat state, the unlocking process of the positioning component 5 is as follows: Pull the pull strap 51, and the pull strap 51 drives the free end of the locking hook 522 to rotate forward and then leave the locking pin 431, that is, the first rotating shaft 41 and the second rotating shaft 44 can rotate; when the free end of the locking hook 522 rotates forward, it drives the pull cable 535 to pull the two locking tops 534 forward, causing the two locking tops 534 to rotate and push the locking tongue 531 that is opposed to them to rotate until the limiting grooves of the two locking tongues 531 rotate to be parallel to the slots on the two mounting rods 45, and the two first limiting rods 54 or the second limiting rod 55 can disengage from the limiting grooves and slots, that is, the two mounting rods 45 can move up, down, forward or backward. After the seat position is switched, the pull strap 51 is released, and the locking hook 522 is reset under the torque of the first torsion spring 523 and hooks the locking pin 431; the locking 534 is reset under the action of the third torsion spring, and the locking tongue 531 is reset under the torque of the second torsion spring, so that the limiting groove and the locking groove cooperate to re-lock the first limiting rod 54 or the second limiting rod 55.

[0062] The child headrest 6 includes two side panels 61, with side panel frames 62 encased inside. The two side panel frames 62 are rotatably mounted on both sides of the backrest frame 11. The two side panel frames 61 can rotate towards each other, and the rotation angle between the two side panel frames 61 and the backrest frame 11 can be adjusted between 0° and 60°. The two side panels 61 are used to restrict and protect the child's head area, improving the child's safety while riding in the car.

[0063] The child armrest 7 includes two armrest boards 71, which are rotatably mounted on both sides of the backrest 1. The two armrest boards 71 ​​can be rotated downwards to be perpendicular to the backrest 1. The two armrest boards 71 ​​are used to place the child's arms and to restrict the child's body area.

[0064] By setting up child grab bars, the area where children can move is limited, improving their safety while not overly restricting their movement, thus enhancing their comfort.

[0065] The five-point safety harness 8 includes safety harnesses 81 and adjustment straps 82. There are five safety harnesses 81. Two safety harnesses 81 are slidably installed above the child's shoulders on the backrest 1, two safety harnesses 81 are slidably installed on both sides of the child's waist on the backrest 1, and one safety harness 81 is slidably installed on the child's seat cushion 3. The free ends of the safety harnesses 81 on the child's seat cushion 3 are sewn with child safety buckles 83, and the free ends of the other four safety harnesses 81 are sewn with inserts that can be inserted into the child safety buckles 83. The two ends of the adjustment straps 82 are sewn with adjustment buckles. The two adjustment buckles are slidably installed on the two safety harnesses 81 located on the child's shoulders, and the spacing between the two safety harnesses 81 can be adjusted according to the child's shoulder width through the adjustment straps 82.

[0066] The five-point safety harness 8 protects the child's shoulders, waist, and hips, preventing the child from slipping or falling off the child seat 3 and ensuring the child's safety while riding in the car. The adjustable strap 82 allows for adjustment of the seat belt spacing according to the child's shoulder width, avoiding both a loose seat belt that reduces safety and a tight seat belt that causes discomfort. The solution provides options for either a three-point or five-point safety harness depending on the child's age, with simple switching and convenient operation, effectively improving the comfort and practicality of the child seat.

[0067] The music headrest 9 is fixedly installed on the backrest 1, and the music headrest 9 is located between the two side panels 61.

[0068] Musical headrests can play music to improve adult passenger comfort, and can also play soothing music to reduce noise from children while traveling.

[0069] The operation steps for switching from adult seat mode to child seat mode according to this invention are as follows:

[0070] Step 1: Pull the pull strap 51 to unlock the first locking member 52 and the second locking member 53. The pull strap 51 will move the child seat cushion 3 forward and slide it out of the mounting slot 22.

[0071] Step 2: Lift the child seat 3 upwards. Once the child seat 3 is completely detached from the base 2, it will rise to its highest point.

[0072] Step 3: Push the child seat 3 backward so that the two second limiting rods 55 are engaged in the slots of the two mounting rods 45;

[0073] Step 4: Loosen the pull strap 51 to lock the first locking member 52 and the second locking member 53.
