[0038] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0039] like Figure 1-8 As shown in the figure, this embodiment discloses a support leg rotation structure for a child safety seat.

[0040] A child safety seat has a support leg extension structure, including a base 100 and a seat body rotatably disposed on the base 100; a support leg assembly 200 is provided at the bottom of the base 100, and one end of the support leg assembly 200 is rotatably connected to the base 100; a storage groove is provided on the lower end surface of the base 100 to accommodate the support leg assembly 200.

[0041] The support leg assembly 200 includes a support leg body 210 and a rotating seat 220 fixed to the upper end of the support leg body 210. The rotating seat 220 and the base 100 are connected by a rotating shaft 1.

[0042] The rotating seat 220 is also provided with a stop shaft 2 arranged parallel to the rotating shaft 1, and the base 100 is provided with a stop component 300, which is provided with a stop groove 311 that can accommodate the stop shaft 2.

[0043] The above is the basic scheme of this embodiment.

[0044] Specific reference Figures 1-2 As shown, when the support leg assembly 200 is in the storage position, the support leg body 210 is embedded in the storage groove in a state parallel to the bottom of the base 100, and at the same time, the rotating seat 220 on the support leg body 210 is located at the front end of the support leg body 210 and is also embedded in the storage groove.

[0045] When the support leg assembly 200 rotates out, the rotating seat 220 rotates around the rotating shaft 1, and at the same time drives the support leg body 210 to rotate out from the storage slot to a position that is approximately right-angled with the end face of the base 100, so that the lower end of the support leg body 210 can be supported on the car floor mat; at the same time, the stop shaft 2 rotates with the rotating seat 220 and slides along the stop component 300 until it is engaged in the stop groove 311.

[0046] It should be noted that, in order to make the support leg body 210 applicable to any type of vehicle and to provide support on car seats of any height, in this embodiment, the support leg body 210 is configured as a telescopic structure, and the telescopic method is consistent with that of the support leg in the prior art.

[0047] In this embodiment, the storage slot includes a T-shaped support leg storage cavity 101 and a rotating cavity 102 connected to the end of the support leg storage cavity 101. The rotating cavity 102 extends to the front end of the base 100 to form an opening.

[0048] The upper end of the rotating cavity 102 extends to the upper surface of the base 100.

[0049] Specific reference Figure 3As shown, in this embodiment, the rotating cavity 102 is configured with three side openings, and both the upper and lower end faces are configured as openings.

[0050] The rotating seat 220 rotates within the rotating cavity 102. The outer surface of the rotating seat 220 is flush with the upper end face and the front end face of the base 100, making the upper opening and the front opening consistent in appearance.

[0051] Specifically, the stop component 300 is a sheet-like structure disposed inside the base 100 and fixed on the two side walls of the rotating cavity 102. The stop groove 311 is located on the upper end surface of the stop component 300, and the upper end surface of the stop component 300 is configured as a clearance surface 310 that connects with the stop groove 311.

[0052] Specific reference Figure 4 As shown, in this embodiment, the base 100 is composed of an upper shell 120 and a lower shell 130 spliced ​​together. The part of the upper shell 120 corresponding to the rotating cavity 102 is set with a notch; the stop component 300 is fixed in the lower shell 130 and closely abuts the two side walls of the rotating cavity 102.

[0053] Reference Figure 5 and Figure 6 As shown, when the support leg assembly 200 is in the retracted state, the stop shaft 2 is located at the outer end of the stop component 300 and is supported on the clearance surface 310; when the rotating seat 220 rotates, it drives the stop shaft 2 to rotate around the rotating shaft 1, and the stop shaft 2 moves in an arc. During this process, the stop shaft 2 is located above the clearance surface 310; when the support leg assembly 200 is in the open state, the stop shaft 2 is inserted into the stop groove 311.

[0054] In other embodiments, the clearance surface 310 may also be configured as an arcuate surface that follows the movement path of the stop shaft 2.

[0055] Preferably, in this embodiment, the opening of the stop groove 311 is configured as a constricted opening structure.

[0056] Based on the above configuration, when the stop shaft 2 moves to the opening of the stop groove 311 and needs to enter the stop groove 311 through the opening, the constriction structure generates an instantaneous damping force on the stop shaft 2, so that the user can perceive that it has rotated into place; at the same time, when the car shakes during driving, due to the restriction of the constriction structure, the stop shaft 2 will not slide out of the stop groove 311, ensuring the stable installation of the support leg assembly 200.

[0057] In this embodiment, the seat body cannot rotate when the support leg assembly 200 is in the retracted state; the seat body can only rotate when the support leg assembly 200 is in the open state. Specifically, a turntable 110 is embedded in the base 100 to drive the seat body to rotate; the turntable 110 is provided with multiple gear slots, and a locking tongue 400 is provided in the base 100 to engage with the gear slots and lock the turntable 110.

[0058] The rotating base 220 is provided with an actuating component 500 for driving the locking tongue 400.

[0059] The embedded structure of the turntable 110 and the base 100, as well as the connection method between the turntable 110 and the seat body, are consistent with those of existing safety seats and will not be described in detail here.

[0060] Reference Figure 7 and Figure 8 As shown, the actuating component 500 is disposed inside the rotating base 220 and rotates around the rotating shaft 1 together with the rotating base 220. When the support leg assembly 200 is in the retracted state, the actuating component 500 is separated from the locking tongue 400 and cannot drive the locking tongue 400 to rotate; when the support leg is in the open state, the actuating component 500 is connected to the locking tongue 400 and can drive the locking tongue 400.

[0061] Specifically, the actuating component 500 includes an operating part 510 and a driving part 520 formed at both ends, and the rotating shaft 1 is located between the operating part 510 and the driving part 520, so that the operating part 510 and the driving part 520 rotate around the rotating shaft 1.

[0062] The end of the latch 400 is provided with a drive groove 401 that can accommodate the drive part 520 extending into.

[0063] Specific reference Figure 7 and Figure 8 As shown, the two ends of the locking tongue 400 are the driving end 410 and the locking end 420, respectively. The locking end 420 extends into the gear slot of the turntable 110 to lock the turntable 110; the driving groove 401 is provided at the driving end 410.

[0064] When the support leg assembly 200 is in the retracted state, the drive part 520 on the actuating member 500 is located above the drive end 410. At this time, the actuating member 500 is not in contact with the locking tongue 400. The actuating member 500 rotates around the rotating shaft 1, causing the drive part 520 to rotate clockwise to the bottom and partially engage in the drive groove 401 of the locking tongue 400, so that the actuating member 500 and the locking tongue 400 form a transmission. At this time, pulling the operating part 510 can drive the locking tongue 400.

[0065] Preferably, in this embodiment, the operating part 510 is embedded in the rotating seat 220, and the outer end face of the operating part 510 is spliced ​​with the surface of the rotating seat 220 to form an integral part.

[0066] Meanwhile, the groove of the rotating seat 220 is larger than that of the operating part 510, leaving an operating space below the operating part 510 for a person to reach in. When the chair body is rotated, the operating part 510 is pulled outward through the operating space. Since the actuating component 500 is rotatably connected to the rotating shaft 1, the actuating component 500 rotates clockwise around the rotating shaft 1 under the action of external force. The driving end 410 of the actuating component 500 has an outward displacement in the horizontal direction, thereby driving the locking tongue 400 to move outward, and the locking end 420 of the locking tongue 400 disengages from the gear slot.

[0067] In this embodiment, a torsion spring 3 is provided on the rotating shaft 1, and the two torsion angles of the torsion spring 3 abut against the actuating component 500 and the rotating seat 220 respectively.

[0068] After the seat body is set in the correct direction, release the operating part 510. The actuating part 500 is reset under the action of the torsion spring 3, and the driving end 410 is withdrawn from the driving groove 401. A return spring 4 is provided between the locking tongue 400 and the inner wall of the base 100. The return spring 4 holds the locking tongue 400 inward, so that the locking end 420 is engaged in the gear slot, thereby locking the turntable 110.

[0069] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
