[0026] The terms "include" and "have" and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0027] The present application will be further described below in conjunction with the drawings:

[0028] As Figures 1 to 3 shown, the present application provides a safety seat power supply structure, which comprises a base 1, a seat body 2 and a power supply module 3, the seat body 2 is arranged on the base 1, in the present application, the base 1 is used to be stably placed on a vehicle seat or the like, and supports the seat body 2, and the seat body 2 is used for children to ride.

[0029] In some embodiments, the seat body 2 is movably arranged on the base 1, and the seat body 2 can rotate on the base 1 to adjust the relative direction between the seat body 2 and the base 1, thereby better protecting the child and improving safety.

[0030] The base 1 is provided with a power supply port 11, and the power supply module 3 is provided with an output port 31, the power supply module 3 is adapted to be connected with the base 1, and the power supply port 11 and the output port 31 are engaged, the power supply module 3 is adapted to supply power to the base 1 through the engaged power supply port 11 and output port 31, since the base 1 is a fixed structure when in use, the connection of the power supply module 3 with the base 1 for power supply can make the power supply state between the power supply module 3 and the safety seat more stable, and reduce the probability of the power supply module 3 falling off.

[0031] By changing the external power supply or built-in battery form of the safety seat into the form of a detachable external power supply module 3, the use of the safety seat is more convenient and easy to maintain. The safety seat no longer needs to be connected to the power supply of the car for use, thereby effectively reducing the length limitation of the wire harness and the adaptability problem of external power supply. When the power supply module 3 is insufficient or fails, the user only needs to replace a new power supply module 3 to quickly restore the normal use of the safety seat. For the manufacturer, the power supply module 3 can be sold and maintained as an auxiliary part. The good or bad of a single power supply module 3 will not directly affect the usability of the seat, reducing the manufacturer's after-sales, operation and maintenance costs.

[0032] In some embodiments, the power supply module 3 is provided with a charging port, and the power supply module 3 can be externally connected to the power supply through the charging port after being detached from the safety seat. It can be understood that by optimizing the power supply circuit and power supply logic inside the power supply module 3, the power supply module 3 can also be externally connected to the power supply through the charging port when it is on the safety seat, and a part of the power can be directly supplied to the safety seat to ensure the normal operation of the electronic functions of the safety seat, realize emergency power supply, and increase the applicability.

[0033] It is worth noting that the power supply module 3 in the present application is different from the dry battery power supply method in the prior art. The power supply module 3 is generally a lithium battery module, and the output power is larger and more stable than that of a dry battery, and the endurance is longer.

[0034] In some embodiments, the power supply port 11 is arranged on the surface of the base 1, and the output port 31 is arranged on the surface of the power supply module 3. The power supply port 11 and the output port 31 are connected to each other in the form of a contact, so that when the power supply module 3 is magnetically attracted to the base 1, the power supply port 11 and the output port 31 can be connected to each other for power supply. It can reduce the use of wire harness plug-in, reduce the connection difficulty, improve the connection smoothness, and further, the power supply port 11 and the output port 31 are suitable for magnetic attraction connection. The power supply port 11 is a magnetic attraction needle female seat, and the output port 31 is a magnetic attraction needle male head.

[0035] In some embodiments, the power supply port 11 and the output port 31 are connected to each other in the form of an interface, such as a type-c, usb-a interface, etc.

[0036] As shown in the embodiment of Figure 1 The first magnetic attraction assembly 12 is arranged on the base 1, and the second magnetic attraction assembly 32 is arranged on the power supply module 3. The first magnetic attraction assembly 12 and the second magnetic attraction assembly 32 are suitable for attracting each other, so that the power supply module 3 is fixed to the base 1. The power supply module 3 and the base 1 are connected by magnetic attraction, which can effectively reduce the disassembly difficulty of the power supply module 3, improve the disassembly efficiency of the power supply module 3, and facilitate the user to detach the power supply module 3 after use and take it home for power supply, so as to use it next time.

[0037] AsFigure 1 In the embodiment shown, the first magnetic attraction assembly 12 includes a plurality of first magnetic attraction portions 121, and the second magnetic attraction assembly 32 includes a plurality of second magnetic attraction portions 321. The first magnetic attraction portions 121 and the second magnetic attraction portions 321 attract each other one by one. The number of the first magnetic attraction portions 121 and the second magnetic attraction portions 321 is increased. In addition to improving the connection stability between the power supply module 3 and the base 1, the second magnetic attraction portions 321 are arranged along the surface of the power supply module 3, and the corresponding state between the first magnetic attraction portions 121 and the second magnetic attraction portions 321 is adjusted. The power supply module 3 can be guided to be attracted to the base 1 in the same state each time through the attraction between the first magnetic attraction portions 121 and the second magnetic attraction portions 321, and the power supply port 11 and the output port 31 are adapted to be engaged.

[0038] In some embodiments, when the power supply module 3 and the base 1 are magnetically attracted, the engagement direction of the power supply port 11 and the output port 31 is the same as the connection direction of the base 1 and the power supply module 3. The power supply port 11 and the output port 31 can be engaged at the same time while the power supply module 3 and the base 1 are connected and attracted, without the need for other operations, thereby improving the smoothness of installation.

[0039] As shown in the embodiment, Figure 2 In the embodiment shown, the base 1 is provided with a power supply slot 13, and the power supply port 11 is arranged in the power supply slot 13. The power supply module 3 is adapted to be fitted into the power supply slot 13. The use of the power supply slot 13 can reduce the occupation of the external space of the safety seat by the power supply module 3, and can improve the connection stability of the power supply module 3 on the safety seat, and reduce the probability of mutual separation of the power supply port 11 and the output port 31 due to automobile vibration.

[0040] In some embodiments, the power supply module 3 is provided with a charging port. When the power supply module 3 is placed in the power supply slot 13, the charging port is exposed outside the power supply slot 13, so that the power supply module 3 can be externally powered when placed in the power supply slot 13, thereby playing a power supply role for the safety seat. In this embodiment, a special power supply interface does not need to be designed on the safety seat for power supply.

[0041] In some embodiments, the power supply port 11 is located at the innermost side of the power supply slot 13, and the power supply module 3 is adapted to engage the output port 31 and the power supply port 11 at the end of the travel of being placed into the power supply slot 13. The power supply port 11 is hidden at the innermost side of the power supply slot 13, thereby improving the safety of the power supply port 11 and reducing the probability of damage to the power supply port 11. Before the power supply module 3 is placed in the power supply slot 13, the output port 31 and the power supply port 11 will not be engaged, thereby avoiding accidental power-on.

[0042] In some embodiments, a first connecting part is provided in the power supply slot 13, and a second connecting part is provided on the power supply module 3. When the power supply module 3 is placed into the power supply slot 13 such that the output port 31 and the power supply port 11 are engaged, the first connecting part and the second connecting part are adapted to cooperate and connect to restrict the relative movement of the power supply module 3 and the power supply slot 13.

[0043] The first and second connecting parts can use a variety of common fastening structures such as snap-fit ​​slots and snap-fit ​​blocks, Velcro, and magnetic blocks.

[0044] like Figure 3 In the embodiment shown, when the power supply module 3 and the base 1 are connected in the form of a power supply slot 13, the engagement direction of the power supply port 11 and the output port 31 is the same as the direction in which the power supply module 3 is inserted into the power supply slot 13. This allows the power supply port 11 and the output port 31 to be engaged when the power supply module 3 is inserted into the base 1. The engaged power supply port 11 and the output port 31 can also prevent the power supply module 3 from detaching from the power supply slot 13.

[0045] In some embodiments, a first sensor 14 is provided on the base 1, and a second sensor 33 is provided on the power supply module 3. The first sensor 14 and the second sensor 33 are adapted to sense and trigger, so that the output port 31 supplies power to the power supply port 11. The first sensor 14 and the second sensor 33 are used to identify each other. When the identification is successful, the power supply port 11 and the output port 31 can be connected, which can avoid abnormal access of other power sources, the situation where the power supply module 3 is not installed in place but the power supply port 11 and the output port 31 are mistakenly connected in advance, and reduce the interference of static electricity and other factors on the circuit of the power supply module 3 when the power supply module 3 is idle.

[0046] In some embodiments, the first sensor 14 and the second sensor 33 are a magnet and a magnetic Hall switch, respectively. When the battery is installed correctly, the magnet will approach the Hall switch, the switch enable circuit will be turned on, and the power supply module 3 will supply power normally.

[0047] In some embodiments, when the power supply module 3 and the base 1 are magnetically connected, the power supply port 11 and the first sensor 14 are located on both sides of the first magnetic component 12, and the output port 31 and the second sensor 33 are located on both sides of the second magnetic component 32.

[0048] In some embodiments, when the power supply module 3 and the base 1 are connected in the form of a power supply slot 13, the base 1 is provided with a power supply slot 13, the power supply port 11 and the first sensor 14 are disposed in the power supply slot 13, and the power supply module 3 is adapted to be fitted into the power supply slot 13.
