Description

Technical Field

[0001] This utility model relates to the field of safety seat technology, specifically to a safety seat that can fit snugly against the car seat. Background Technology

[0002] When a child safety seat is installed in a car seat, the locking mechanism of the safety seat is fastened to the car seat installer, making it difficult to fit the base of the safety seat tightly to the car seat. In the event of sudden braking or impact, the gaps can cause the safety seat to become loose and unstable, creating a sense of insecurity for the infant or child placed in the safety seat. Utility Model Content

[0003] This utility model addresses one of the problems existing in the prior art to a certain extent. Therefore, one objective of this utility model is to provide a safety seat that can fit snugly against the car seat, with the base fitting snugly against the car seat.

[0004] The above objective is achieved through the following technical solution:

[0005] A safety seat that fits snugly against a car seat includes a base and a locking structure. The locking structure is movably mounted on the base and can move to an extended or retracted state on the base. The locking structure has multiple locking holes, and a locking member is provided on the base. The engaging portion of the locking member extends towards the locking structure. When the engaging portion extends and engages with the locking holes, it restricts the locking structure from moving in the extending direction relative to the base. A sliding slope is formed at one end of the engaging portion facing the car seat. When the base moves towards the car seat, the sliding slope engages with the edge of the locking hole to push the engaging portion away from the locking hole.

[0006] As a further improvement of this utility model, the locking member is rotatably mounted on the base. The locking member can rotate on the base until the fastening part extends out of or disengages from the locking hole. A first return spring is provided on the base. One end of the first return spring contacts the inner wall of the base and the other end contacts the locking member to push the fastening part to extend out of the locking hole.

[0007] As a further improvement of this utility model, it also includes a limiting member, which is installed on the base and extends toward the locking structure. The locking structure is provided with a limiting hole. When the locking structure moves out to the maximum extension distance relative to the base, the limiting member engages with the limiting hole.

[0008] As a further improvement of this utility model, it also includes a second return spring, one end of which contacts the inner wall of the base and the other end of which contacts the limiting member, so as to push the limiting member to extend in the direction of the locking structure.

[0009] As a further improvement of this utility model, it also includes a push rod, which is movably installed in the locking structure and is used to push the limiting member away from the limiting hole.

[0010] As a further improvement of this utility model, a pushing slope is formed on the push rod, and a mating slope is formed at the end of the limiting member extending into the limiting hole. The pushing slope and the mating slope cooperate so that when the base moves toward the steam seat, the limiting member is pushed out from the limiting hole through the cooperation of the pushing slope and the mating slope.

[0011] As a further improvement of this utility model, a limiting post is provided in the locking structure, and a sliding hole is formed on the locking structure. The limiting post extends into the sliding hole, and the movement distance of the push rod in the locking structure is limited by the cooperation between the limiting post and the sliding hole.

[0012] As a further improvement of this utility model, it also includes a third reset spring, one end of which contacts the limiting post and the other end of which contacts the front end face of the sliding hole.

[0013] As a further improvement of this utility model, a pushing plane is also formed on the push rod, the pushing plane is connected to the pushing inclined surface, and the pushing plane cooperates with the mating inclined surface to push the limiting member out from the limiting hole.

[0014] As a further improvement of this utility model, the locking structure includes a fastening frame and a connecting frame. The fastening frame is used to connect with the gas seat, and the fastening frame is connected to the connecting frame. The connecting frame is provided with the locking hole.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] 1. This utility model proposes a safety seat that can fit snugly against the car seat. When the locking structure is connected to the car seat, the base can move towards the car seat while restricting the base from moving away from the car seat until the base is snugly against the car seat, thus avoiding the situation where there is a gap between the base and the car seat after the locking structure is connected to the car seat.

[0033] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0034] like Figure 1-16 A safety seat that fits snugly against a car seat includes a base 1 and a locking structure 2. The locking structure 2 is movably mounted on the base 1 and can move on the base 1 to an extended or retracted state. The locking structure 2 has multiple locking holes 211. The base 1 has a locking member 11. The latching part 111 of the locking member 11 extends toward the locking structure 2. When the latching part 111 extends and engages with the locking holes 211, it restricts the locking structure 2 from moving in the extended direction relative to the base 1. A moving-out inclined surface 1111 is formed on the end of the latching part 111 facing the car seat. When the base 1 moves toward the car seat, the moving-out inclined surface 1111 engages with the edge of the locking hole 211 to push the latching part 111 out of the locking hole 211.

[0035] This utility model proposes a safety seat that can fit snugly against the car seat. When the locking structure 2 moves to the extended state on the base 1, the fastening part 111 of the locking member 11 extends towards the locking structure 2, and the fastening part 111 engages with the locking hole 211. At this time, the movement of the locking structure 2 in the extended direction can be restricted, and the movement of the base 1 away from the car seat can also be restricted.

[0036] When the locking structure 2 is connected to the steam seat, the base 1 can move towards the steam seat without needing an unlocking device. That is, after the locking structure 2 is connected to the steam seat, the base 1 moves towards the steam seat relative to the locking structure 2. At this time, the inclined surface 1111 engages with the edge of the locking hole 211, and the edge of the locking hole 211 pushes the latching part 111 of the locking member 11 away from the locking hole 211, causing the latching part 111 to disengage from the locking hole 211. This allows the base 1 to move smoothly towards the steam seat, and the base 1 can fit snugly against the steam seat. Figure 16 .

[0037] This utility model proposes a safety seat that fits snugly against the car seat. When the locking structure 2 is connected to the car seat, it restricts the base 1 from moving away from the car seat while allowing the base 1 to move closer to the car seat. This ensures that the base 1 fits snugly against the car seat, avoiding any gaps between the base 1 and the car seat after the locking structure 2 is connected. Figure 15 .

[0038] In some embodiments, a seat body 100 is also included, which is mounted on the base 1.

[0039] The locking member 11 is rotatably mounted on the base 1. The locking member 11 can rotate on the base 1 to extend or disengage the latching part 111 towards the latching hole 211. A first return spring 12 is provided on the base 1, with one end of the first return spring 12 contacting the inner wall of the base 1 and the other end contacting the locking member 11 to push the latching part 111 to extend towards the latching hole 211. That is, in the normal state, the locking member 11 always rotates towards the locking structure 2 so that the latching part 111 extends towards the latching hole 211.

[0040] The fastening portion 111 has a moving inclined surface 1111 at one end facing the gas seat, and an abutting plane 1112 at the end away from the gas seat. In some embodiments, the cross-section of the fastening portion 111 is triangular.

[0041] In some embodiments, a protrusion 112 is formed at the locking member 11, and one end of the first return spring 12 that contacts the locking member 11 is mounted on the protrusion 112.

[0042] In some embodiments, the first reset spring 12 is a first reset compression spring.

[0043] It also includes a limiting member 3, which is installed on the base 1 and extends toward the locking structure 2. The locking structure 2 is provided with a limiting hole 212. When the locking structure 2 moves out of the base 1 to the maximum extension distance, the limiting member 3 engages with the limiting hole 212.

[0044] In this embodiment, the limiting hole 212 is located at the end away from the steam seat, and the locking hole 211 is located at the end close to the steam seat.

[0045] In this embodiment, the limiting member 3 is located near the bottom of the base 1, and the locking member 11 is located near the top of the base 1, that is, the limiting member 3 is located above the locking member 11.

[0046] In this embodiment, the size of the limiting hole 212 is larger than the size of the locking hole 211. The limiting hole 212 can not only engage with the limiting member 3, but also engage with the fastening part 111 of the locking member 11.

[0047] In this embodiment, when the limiting member 3 extends into the limiting hole 212, the fastening part 111 of the locking member 11 can also be inserted into the limiting hole 212. However, since the locking hole 211 only cooperates with the fastening part 111, the limiting member 3 cannot extend into the locking hole 211.

[0048] It also includes a second return spring 13, one end of which contacts the inner wall of the base 1 and the other end of which contacts the limiting member 3, so as to push the limiting member 3 to extend towards the locking structure 2.

[0049] In some embodiments, the second reset spring 13 is a second reset compression spring.

[0050] Due to the second return spring 13, the limiting member 3 is always extended in the direction of the locking structure 2.

[0051] It also includes a push rod 4, which is movably installed in the locking structure 2, and the push rod 4 is used to push the limiting member 3 away from the limiting hole 212.

[0052] A pushing slope 41 is formed on the push rod 4, and a mating slope 31 is formed at the end of the limiting member 3 that extends into the limiting hole 212. The pushing slope 41 and the mating slope 31 are mated together so that when the base 1 moves toward the steam seat, the limiting member 3 is pushed out from the limiting hole 212 through the mating slope 41 and the mating slope 31.

[0053] A cavity with one open end is formed within the locking structure 2, and the push rod 4 extends into the cavity towards the opening. A limiting post 24 is provided within the locking structure 2, and a sliding hole 26 is formed on the locking structure 2. The limiting post 24 extends into the sliding hole 26, and the movement distance of the push rod 4 within the locking structure 2 is limited by the cooperation between the limiting post 24 and the sliding hole 26.

[0054] In this embodiment, by the limiting post 24 abutting against the sliding hole 26, the movement distance of the push rod 4 in the cavity toward the opening direction (i.e. forward) can be limited.

[0055] It also includes a third return spring 25, one end of which contacts the limiting post 24 and the other end of which contacts the front end face of the sliding hole 26, so as to push the push rod 4 to extend in the opening direction, so that the push rod 4 always remains in the forward extended state.

[0056] A locking member is provided at the opening. When the connecting member of the steam seat extends into the opening and connects with the locking member, it pushes the push rod 4 to move backward, so that the pushing inclined surface 41 moves toward the limiting hole 212, so that the limiting member 3 is pushed by the pushing inclined surface 41 and the pushing plane 42, so that the limiting member 3 is disengaged from the limiting hole 212.

[0057] A pushing plane 42 is also formed on the push rod 4. The pushing plane 42 is connected to the pushing inclined surface 41, and the pushing plane 42 cooperates with the mating inclined surface 31 so that the limiting member 3 is pushed out from the limiting hole 212.

[0058] In this embodiment, the pushing plane 42 is located at the front end of the pushing inclined surface 41, that is, the pushing plane 42 is at the end closer to the steam seat, and the pushing inclined surface 41 is at the end farther away from the steam seat. The pushing inclined surface 41 interacts with the mating inclined surface 31 of the limiting member 3, causing the limiting member 3 to move outward from the limiting hole 212. Furthermore, the pushing plane 42 contacts the limiting member 3, completely pushing the limiting member 3 out of the limiting hole 212.

[0059] When the connecting piece of the steam seat extends into the opening and connects with the clamping piece, the pushing inclined surface 41 and the pushing plane 42 are located at the lower end of the limiting hole 212.

[0060] When the locking structure 2 is fully extended, both the limiting member 3 and the engaging portion 111 of the locking member 11 extend into the limiting hole 212 and engage. The locking member 11 cooperates with the exiting inclined surface 1111 of the engaging portion 111 through the edge of the limiting hole 212 to push the locking member 11 outward.

[0061] It also includes an unlocking mechanism, which includes a button and a pull cord. One end of the pull cord is connected to the button, and the other end is connected to the locking member 11, so that pressing the button will cause the locking member 11 to disengage from the latch hole 211.

[0062] When the latching part 111 of the locking member 11 extends into the latch hole 211, the abutting plane 1112 abuts against the latch hole 211 to restrict the locking structure 2 from moving in the extension direction relative to the base 1, the locking member 11 can be rotated away from the latch hole 211 by pressing the button and pulling the pull rope through the unlocking mechanism, so that the locking member 11 disengages from the latch hole 211 and the locking structure 2 moves in the extension direction relative to the base 1.

[0063] The locking structure 2 includes a fastening frame and a connecting frame 21. The fastening frame is used to connect with the gas seat. The fastening frame is connected to the connecting frame 21. The connecting frame 21 is provided with the locking hole 211.

[0064] In this embodiment, the locking structure 2 can extend forward relative to the base 1, and the locking structure 2 can retract backward relative to the base 1.

[0065] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
