[0002] For families with infants and young children, who are still at an age where they cannot walk or have only walked for a short time, they need to carry child seats and strollers when going out. The strollers are usually placed in the trunk and need to be folded and stored when getting in and out of the car. If there is a lot of luggage, the strollers will take up more space, and the strollers and child seats need to be replaced in different situations. This can easily disturb the rest of comfortably sleeping infants and young children, and can cause a series of inconveniences later. Therefore, it is very inconvenient for many families with infants and young children to go out. Summary of the invention

[0003] The embodiment of the present application provides a child seat to solve the defect in the related art that it is inconvenient for families with infants and young children to go out.

[0004] An embodiment of the present application provides a child seat, comprising a seat with wheels telescopically connected thereto; a base for connecting to a rear seat in the vehicle, the base being provided with a groove; an adjustment component having one end connected to the seat and the other end connected to the wheel, the adjustment component being used to adjust the telescopic state of the wheel, the wheel being used to engage with the groove when retracted, and being used to move on the ground when extended.

[0005] By adopting the above technical solution: by using the adjustment component to adjust the telescopic state of the wheel, when the wheel is retracted, it is used to engage with the groove, which can ensure that the seat is stable in the car and prevent it from moving or tipping over during driving. When the wheel is extended, it is used to move on the ground, so that the entire seat can be pushed like a cart, which is convenient for parents to move the child seat outside the car. Therefore, the functions of fixing inside the car and moving outside the car are combined together, which not only ensures the safety of the child in the car, but also improves the convenience of parents moving the seat outside the car.

[0006] In some embodiments, a sensor is provided on the seat for monitoring the temperature of the seat back.

[0007] By adopting the above technical solution: the sensor can be effectively used to monitor the temperature of the seat back. If the temperature of the child's back is too high, it will be detected by the sensor, and the guardian nearby will be reminded in time to dissipate heat for the child.

[0008] In some embodiments, the seat back is provided with a ventilation fan, and the ventilation fan is connected to the sensor signal.

[0009] By adopting the above technical solution: when in use, after the sensor issues a high temperature warning, the ventilation fan can be turned on to cool down the child in time. The ventilation fan can effectively reduce the temperature and provide a more comfortable riding environment for the child.

[0010] In some embodiments, the adjustment assembly includes a push rod, which is composed of multiple telescopic joints, and one end of the push rod is rotatably connected to the seat, and the other end is connected to the wheel; a locking member, which is connected to the telescopic joint and is used to lock the telescopic connection between the multiple telescopic joints; a fixing assembly, which is connected to an telescopic joint rotatably connected to the seat, and the fixing assembly is used to fix the telescopic joint to the seat.

[0011] By adopting the above technical solution: when in use, multiple telescopic sections are stretched until the push rod is adjusted to a suitable length, and then the telescopic sections are locked by using a locking piece; then the use angle of the push rod is adjusted by rotating to ensure that the seat is quickly converted into a child stroller. The synergistic effect of the locking piece and the fixing assembly can ensure the stability and safety of the push rod after adjustment, and the seat and wheels can be kept stably connected and supported even under complex or harsh driving conditions.

[0012] In some embodiments, the locking member includes a locking spring pin, and at least three of the telescopic joints are provided. The locking spring pin is connected to the middle telescopic joint, and the telescopic joints at the other two ends are provided with slots adapted to the locking spring pin.

[0013] By adopting the above technical solution: when in use, when pulling multiple telescopic joints during the stretching or contraction process, the locking spring pin can be deformed when subjected to external force, so the locking spring pin contracts when squeezed, and returns to its original state and is connected to the slot after the external force disappears. The adaptation design of the locking spring pin and the slot makes it difficult for the telescopic joint to loosen or fall off after connection.

[0014] In some embodiments, the fixing assembly includes a fixing block, the telescopic joint is connected to the seat via a rotating shaft, a through slot is provided on the rotating shaft, the fixing block is symmetrically connected in the through slot, and a fixing slot adapted to the fixing block is provided on the seat; a connecting spring, one end of which is connected to the fixing block, and the other end is connected to the inner wall of the through slot; a driving member, which is connected to the telescopic joint and is used to drive the fixing block to extend from the through slot and connect to the fixing slot.

[0015] By adopting the above technical solution: by rotating and adjusting the telescopic joint, the angle between the push rod and the seat can be adjusted, thereby ensuring that the seat can be pushed and used normally. After the telescopic joint is rotated and adjusted, the fixed block is driven by the driving member to extend out of the through groove and is inserted and fixed in the fixed groove, thereby effectively fixing the telescopic joint, which is easy to operate and has a reliable structure.

[0016] In some embodiments, the driving member includes a fixing bolt, a threaded hole connected to the through groove is provided on the rotating shaft, the opposite ends of the two fixing blocks are arranged with an inclined surface, the fixing bolt passes through the threaded hole and abuts against the inclined surface of the fixing block, and the fixing bolt is threadedly matched with the rotating shaft through the threaded hole.

[0017] By adopting the above technical solution: during use, when the telescopic joint and the seat are in a rotationally connected state, the fixing bolt is separated from the fixing block and connected in the threaded hole until the telescopic joint adjusts its connection angle, and then the fixing bolt is rotated to make the fixing bolt abut against the inclined surface of the fixing block. At this time, the provided connecting spring is deformed, and the fixing block is abutted by the fixing bolt to produce displacement until it extends out of the through groove and is inserted into the fixing groove, thereby effectively fixing the telescopic joint. The fixing bolt is effectively locked by cooperating with the thread of the threaded hole, and the structure is reliable.

[0018] In some embodiments, a limiting spring pin is provided on the inner wall of the groove, and the limiting spring pin abuts against the seat.

[0019] By adopting the above technical solution: the limiting spring pin utilizes its elastic force to abut against the seat, thereby effectively reinforcing the seat, further improving the fixation of the seat in the vehicle and improving safety.

[0020] In some embodiments, the chair includes a seat body, which is used to be placed on the base; and a push handle, which is connected to the back of the seat body.

[0021] By adopting the above technical solution: the setting of the seat and the push handle is more in line with the design and use of the cart, making it easier for people of different heights to push the seat to move.

[0022] In some embodiments, the base is configured as a rotating base.

[0023] By adopting the above technical solution, the rotating base can turn the front of the seat to face the guardian, which is more convenient for looking after infants and young children and has high practical value.

[0024] The beneficial effects of the technical solution provided by this application include:

[0025] The embodiment of the present application provides a child seat, which includes a seat with wheels telescopically connected thereto; a base, which is used to be connected to the rear seat in the vehicle, and the base is provided with a groove; an adjustment component, one end of which is connected to the seat and the other end is connected to the wheel, and the adjustment component is used to adjust the telescopic state of the wheel, and when the wheel is retracted, it is used to engage with the groove, and when the wheel is extended, it is used to move on the ground.

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0038] The embodiment of the present application provides a child seat, which can solve the defect of inconvenience for families with infants and young children to go out.

[0039] See also Figures 1 to 8 As shown, the embodiment of the present application provides a child seat, including a seat 1 base 3 and an adjustment component, wherein the seat 1 is the main part for children to sit on, providing a comfortable sitting and lying space, and the seat 1 part is usually designed in accordance with children's ergonomics to ensure the comfort of long-term sitting. In other embodiments, it may also be equipped with safety and comfort accessories such as seat belts, armrests, and headrests. In the present application, the wheel 2 is telescopically connected to the seat 1, and this connection method allows the wheel 2 to be extended when needed and retracted when not needed. The provided base 3 is used to be connected to the rear seat in the car, and a groove 30 is provided on the base 3; one end of the adjustment component is connected to the seat 1, and the other end is connected to the wheel 2. The adjustment component is used to adjust the telescopic state of the wheel 2. When the wheel 2 is retracted, it is used to engage with the groove 30, which can ensure that the seat 1 is stable and immobile in the car to prevent movement or tipping during driving. When the wheel 2 is extended, it is used to move on the ground, so that the entire seat 1 can be pushed like a car, which is convenient for parents to move the child seat 1 outside the car. And the wheel 2 is usually made of wear-resistant and non-slip materials to ensure stability and safety on different ground surfaces. The ingenious design of the present application combines the functions of fixing inside the car with moving outside the car, which not only ensures the safety of the child in the car, but also improves the convenience of parents moving the seat 1 outside the car.

[0040] In this application, it is very important to ensure the comfort of the child on the seat 1, because too high a temperature may cause discomfort to the child or even cause health problems. Therefore, a sensor 4 is also provided on the seat 1, and is particularly located in an area that can effectively monitor the temperature of the back of the seat 1, so that it can be effectively used to monitor the temperature of the back of the seat 1. If the temperature of the child's back is too high, it will be detected by the sensor 4, and the guardian nearby will be promptly reminded to perform heat dissipation treatment for the child.

[0041] In the present application, a ventilation fan 6 is provided on the back of the seat 1, and the ventilation fan 6 is connected to the sensor 4 signal. Therefore, after the sensor 4 issues a high temperature warning, the ventilation fan 6 can be turned on to cool down the child in time, and the ventilation fan 6 can effectively reduce the temperature and provide a more comfortable riding environment for the child. In addition, in the present application, an adjustment button (not shown in the figure) can be provided on the seat 1, and the ventilation fan 6 can be started or adjusted by the adjustment button to ensure that the wind feeling suitable for the child's comfort is provided to the child, which helps to reduce the discomfort and irritability caused by high temperature and improve the child's riding experience.

[0042] In the present application, the adjustment component provided includes a push rod, a locking member and a fixing member, wherein the push rod is composed of a plurality of telescopic joints 7, the telescopic joints 7 can be nested with each other and telescoped axially to achieve a change in length, and one end of the push rod is rotatably connected to the seat 1, and the other end is connected to the wheel 2; the locking member is connected to the telescopic joint 7, and the fixing member is connected to a telescopic joint 7 rotatably connected to the seat 1.

[0043] When the seat 1 needs to be used under the vehicle, the wheel 2 is first taken out of the groove 30, and the multiple telescopic joints 7 are stretched until the push rod is adjusted to a suitable length, and then the multiple telescopic joints 7 are telescopically locked by the locking member; then the use angle of the push rod is adjusted to ensure that the push rod meets the use requirements and is stable and reliable during the movement of the wheel 2. Therefore, a fixing assembly is used to fix the telescopic joint 7 on the seat 1, thereby effectively converting the fixed seat 1 on the vehicle into a movable cart under the vehicle. The synergistic effect of the locking member and the fixing assembly can ensure the stability and safety of the push rod after adjustment. Even under complex or harsh driving conditions, the stable connection and support of the seat 1 and the wheel 2 can be maintained. Therefore, the present application realizes the height and position adjustment function between the seat 1 and the wheel 2 through the mutual cooperation of the locking member and the fixing assembly, while ensuring the stability and safety after adjustment.

[0044] In the present application, the locking member includes a locking spring pin 8, and at least three locking spring pins 8 are provided on the telescopic joint 7. The locking spring pin 8 is connected to the middle telescopic joint 7, and the telescopic joints 7 at the other two ends are provided with a slot adapted to the locking spring pin 8. In order to connect the locking spring pin 8 to the telescopic joint 7, a slot is provided on the middle telescopic joint 7, which will not be described in detail. When in use, when pulling multiple telescopic joints 7 in the stretching process or the contraction process, the locking spring pin 8 can be deformed when subjected to external force, so the locking spring pin 8 shrinks in the connected slot when squeezed until it returns to its original state after the external force disappears. In the present application, the locking spring pin 8 is connected to the slot on the adjacent telescopic joint 7, thereby achieving locking and fixing, and realizing the locking function. The locking spring pin 8 can quickly adjust the length of the push rod, thereby ensuring that the push rod can meet both the on-vehicle use state and the off-vehicle use state, that is, when used on the vehicle, the telescopic joint 7 is in a contracted state, and when used under the vehicle, the telescopic joint 7 is in a stretched state. Since the locking spring pin 8 has a certain elasticity, it can adapt to the slight deformation of the telescopic joint 7 under vibration, force or other external forces, thereby maintaining the stability and reliability of the connection. The matching design of the locking spring pin 8 and the card slot makes it difficult for the telescopic joint 7 to loosen or fall off after connection. This stability is crucial to ensure the overall performance and safety of the mechanical structure.

[0045] In the present application, the fixed assembly provided includes a fixed block 90, a connecting spring 91 and a driving member, wherein the telescopic section 7 is connected to the seat 1 through the rotating shaft 70, specifically, the first telescopic section 7 at the end is connected to the seat 1, and then a through groove 71 is provided on the rotating shaft 70, and the fixed block 90 is symmetrically connected in the through groove 71, and the two fixed blocks 90 can extend out from the two ends of the through groove 71, so that a fixed groove 13 adapted to the fixed block 90 is provided on the seat 1, and the fixed block 90 can be inserted in the fixed groove 13; and one end of the connecting spring 91 is connected to the fixed block 90, and the other end is connected to the fixed block 90. The inner wall of the through slot 71 is connected, thereby effectively connecting the fixed block 90 to the through slot 71; the driving member is connected to the telescopic joint 7, and is used to drive the fixed block 90 to extend out of the through slot 71 and connect with the fixed slot 13, thereby effectively fixing the rotation of the telescopic joint 7 to ensure that after multiple telescopic joints 7 are extended for use, the angle between the telescopic joint 7 and the seat 1 is adjusted according to the use requirements, and finally the fixed block 90 is driven by the driving member to extend out of the through slot 71 and is inserted and fixed in the fixed slot 13, effectively fixing the telescopic joint 7, ensuring the normal use of the push rod during the movement of the seat 1.

[0046] In the present application, the driving member includes a fixing bolt 92, a threaded hole 72 connected to the through slot 71 is provided on the rotating shaft 70, and the opposite ends of the two fixing blocks 90 are provided with an inclined surface, and the fixing bolt 92 passes through the threaded hole 72 to abut against the inclined surface of the fixing block 90, and the fixing bolt 92 is threadedly matched with the rotating shaft 70 through the threaded hole 72. Therefore, when the telescopic section 7 and the seat 1 are in a rotational connection state, the fixing bolt 92 is separated from the fixing block 90 and connected in the threaded hole 72 until the telescopic section 7 adjusts its connection angle, and the fixing bolt 92 is rotated so that the fixing bolt 92 abuts against the inclined surface of the fixing block 90, at which time the connection spring 91 provided is deformed, and the fixing block 90 is abutted by the fixing bolt 92 to be displaced until it extends out of the through slot 71 and is inserted into the fixing slot 13, thereby effectively fixing the telescopic section 7, and the fixing bolt 92 is effectively locked by threading with the threaded hole 72, and the structure is reliable. In addition, when the seat 1 is used in a vehicle, the multiple upper sections need to be retracted to a state where the wheel 2 is engaged with the groove 30. At this time, the telescopic section 7 needs to be fixed, and the fixing bolt 92 is loosened to separate the fixing bolt 92 from the fixing block 90. ​​Under the elastic force of the connecting spring 91, the fixing block 90 can be automatically reset, and the structure is reliable. The use of the connecting spring 91 also provides a certain buffering and shock absorbing effect, which helps to reduce the vibration and noise caused by movement or external force impact.

[0047] In the present application, when the push rod is retracted, after the rotation fixation of the telescopic joint 7 is released, the telescopic joint 7 can be rotated and adjusted relative to the seat 1, and then when the wheel 2 is adjusted back to a state where it can be engaged with the groove 30, the resetting method of the two push rods on the same side includes but is not limited to using the two push rods on the same side to rotate and fold relative to each other so that the wheel 2 is close to the seat 1, and the wheels 2 on the same side can also be rotated relative to each other so that the two wheels 2 are side by side and close to each other and located on the same plane. There are other ways to store the wheels 2, which will not be elaborated here. The present application shows the relative rotation and staggered folding method of the push rods, and the folding of the wheels 2 can meet the use requirements, with a simple structure and easy operation.

[0048] In the present application, when the wheel 2 is engaged into the groove 30, in order to further improve the connection reliability between the seat 1 and the base 3, a limiting spring pin 31 is provided on the inner wall of the groove 30, and a receiving groove 32 is provided on the inner wall of the groove 30. The limiting spring pin 31 is connected in the receiving groove 32. The limiting spring pin 31 abuts against the seat 1 by its elastic force, thereby effectively reinforcing the seat 1. When the seat 1 is removed for use, the limiting spring pin 31 is squeezed and contracted by only lifting the seat 1. The seat 1 is easy to take and put, and the structure is stable.

[0049] When the seat 1 is fixed on the base 3, infants and young children can be taken care of in the car. In order to further improve the convenience of using the seat 1 in the car, the base 3 is also set as a rotating seat. The rotation of the seat 1 can be self-locking. The structure used includes but is not limited to a ratchet pawl structure or a worm gear structure. Such structures are common means and will not be described in detail in this application. The rotating base 3 can turn the front of the seat 1 to face the guardian, making it easier to take care of infants and young children.

[0050] In the present application, the seat 1 provided includes a seat body 10 and a push handle 11, the seat body 10 is used to be placed on the base 3; the push handle 11 is connected to the back of the seat body 10, and like the common trolleys on the market, the push handle 11 is configured to be retractable, which is convenient for the guardian to push the seat 1 to move under the vehicle, and to conveniently adjust it according to the height of different people, which is very reliable.

[0051] The implementation principle of the embodiment of the present application is as follows: the use of the seat 1 is divided into two states: on the vehicle and under the vehicle. When used on the vehicle, the seat 1 is used as a child safety seat 1. When used under the vehicle, the seat 1 is converted into a child stroller. When used on the vehicle, the push rod is retracted, and the wheel 2 is clamped in the groove and fixed, so that the seat 1 is effectively installed on the base 3, and under the action of the limit spring pin 31, the connection between the seat 1 and the base 3 is reinforced, and the structure is reliable; when used under the vehicle, the multiple telescopic joints 7 are elongated, and the telescopic joints 7 are fixed by the locking spring pin 8, and then the relative angle between the telescopic joint 7 and the seat 1 is rotated to ensure the normal movement of the push rod, and the fixing bolt 92 is used to connect with the threaded hole 72, and the fixing bolt 92 drives the fixing block 90 to be inserted in the fixing groove 13, thereby effectively fixing the rotation of the telescopic joint 7, and the structure is stable. The use of the seat 1 meets different usage requirements, which is convenient for families to carry infants and young children when traveling, and is very reliable.
