DETAILED DESCRIPTION

[0022] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0023] Embodiment

[0024] Please refer to Figs. 1-3 , a portable child car seat quick release mechanism shown in the drawing, comprising:

[0025] The seat body 100 is bolted with a handrail 110 at the top, and the seat body 100 is provided with a backrest 103 at the rear side. The bottom of the handrail 110 is bolted with an extension column 130. The extension column 130 uses a common electric push rod on the market. The electric push rod is a device that combines an electric motor and a linear push rod together, which is used to provide linear motion in a mechanical system. The electric push rod is usually composed of an electric motor, a transmission system and a push rod. The working principle of the electric push rod is that the transmission system is driven by the electric motor to make the push rod run linearly, thereby driving the displacement ring 120 to displace. The extension column 130 is electrically connected with a control switch 131 arranged on the side wall of the handrail 110. The control switch 131 uses a common reverse switch on the market. The backrest 103 is provided with a common rechargeable battery at the rear side. The control switch 131 is electrically connected to the battery. The battery supplies power to the extension column 130 through the control switch 131. The power output end of the extension column 130 is provided with a displacement ring 120. The displacement ring 120 is made of common stainless steel and is solid inside.

[0026] The locking plate 200 is matched to the bottom of the seat body 100. The bottom of the locking plate 200 is provided with a clamping groove 210 matched to the displacement ring 120. The top of the locking plate 200 is provided with a limiting strip 220 and a positioning block 230. The limiting strip 220 is matched to the side wall of the mounting beam 300. The side wall of the limiting strip 220 is provided with a matching surface 221. The matching surface 221 is an arc surface which can be matched to the side wall of the mounting beam 300.

[0027] The mounting beam 300 is matched to the top of the locking plate 200. The mounting beam 300 is internally provided with a connecting column 301 and a welding plate 310. The top of the welding plate 310 is provided with a positioning hole 311 matched to the positioning block 230.

[0028] Specifically, the top of the handrail 110 is provided with a rubber sheet 111.

[0029] Further, the top of the displacement ring 120 penetrates a limiting column 121. The limiting column 121 fixedly limits the displacement ring 120 when the displacement ring 120 slides.

[0030] Further, the limiting column 121 is fixedly connected to the bottom of the handrail 110.

[0031] Further, the seat body 100 is provided with a baffle 101 matched with the displacement ring 120.

[0032] It is worth mentioning that the side wall of the baffle 101 is fixedly connected with a blocking strip 102 matched with the displacement ring 120.

[0033] It is worth noting that the mounting beam 300 is arranged at the bottom of the seat body 100, when the displacement ring 120 is displaced upward under the action of the retracting of the telescopic column 130, the locking plate 200 clamped on the mounting beam 300 is pulled upward, so that the mounting beam 300 is pressed and tightly fitted on the bottom of the seat body 100, and the locking plate 200 is matched with the inside of the displacement ring 120 and cannot be displaced, and the locking plate 200 is clamped on the mounting beam 300, so that the seat body 100 and the mounting beam 300 are locked and connected.

[0034] In addition, the circuit, electronic components and modules involved in the utility model are prior art, and those skilled in the art can realize them without further description, and the content protected by the utility model does not involve improvement of internal structure and method;

[0035] Working principle: after the telescopic column 130 is stretched, the displacement ring 120 is displaced downward, at this time, the locking plate 200 is displaced downward under the action of the displacement ring 120, so that the locking plate 200 is disengaged from the clamping of the mounting beam 300, and then the clamping plate is pulled out outward, so that the seat body 100 is disconnected with the mounting beam 300, thereby the quick disassembly of the child car seat can be realized, the trouble of disassembling the child car seat by using tools is saved, and the convenience of disassembling the portable child car seat is increased; when the child car seat is placed on the mounting beam 300, the locking plate 200 is inserted through the displacement ring 120, and is matched with the positioning hole 311 of the welding plate 310 and the limiting strip 220 and the mounting beam 300, so that the locking plate 200 is clamped on the bottom of the mounting beam 300, at this time, the telescopic column 130 is retracted to drive the displacement ring 120 to be clamped in the clamping groove 210 at the bottom of the locking plate 200, so that the locking plate 200 is clamped, thereby the positioning block 230 and the limiting strip 220 on the locking plate 200 are matched with the welding plate 310 to be clamped, which can improve the stability of the locking plate 200 when locking the seat body 100, so that the connection between the seat body 100 and the mounting beam 300 is more close, which is beneficial to the long-term installation and use of the seat body 100.

[0036] It is to be noted that, in the present document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.
