Description

[Technical Field]

[0001] This utility model relates to the field of child safety travel products technology, and in particular to a child safety seat base and child safety seat that can be easily unlocked from either side. [Background Technology]

[0002] Child safety seats typically consist of a seat and a base. The base includes a base body and a turntable rotatably mounted on the base body. The seat is detachably connected to the turntable, allowing the seat to rotate relative to the base body. Therefore, the seat can be rotated to face directly towards the vehicle or to face away from the vehicle. When the seat is facing directly towards the vehicle, it is in a forward-facing mode; when it is facing away from the vehicle, it is in a rear-facing mode; and when it is facing towards the door, it is in a side-facing mode. The turntable is usually locked to the base body by a locking mechanism, which requires an unlocking mechanism to unlock when locked.

[0003] When adjusting the above modes, the user is generally located outside the rear door of the vehicle and must reach into the vehicle to operate the mechanism. In existing technology, in order to allow the child safety seat base to be unlocked from both the left and right sides of the rear door, the unlocking mechanism is correspondingly equipped with unlocking operation parts on both the left and right sides of the child safety seat base; however, this structural solution has the problems of complex structure and high manufacturing cost.

[0004] Therefore, this utility model was developed to address the aforementioned problems. [Utility Model Content]

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a child safety seat base and child safety seat that can be easily unlocked from either side. By configuring only one operating component so that the user can operate it from both the left and right sides of the car safety seat base to unlock the turntable, the unlocking operation structure is effectively optimized, manufacturing costs are reduced, and the overall structure is made simpler.

[0006] This utility model provides a child safety seat base that can be easily unlocked from either side, including a base body 1. A turntable 2 is rotatably connected to the base body 1. A locking mechanism 3 for locking the turntable 2 is provided between the base body 1 and the turntable 2. The base body 1 is also provided with an unlocking component 4 for releasing the locking state between the base body 1 and the turntable 2 by linking the locking mechanism 3. The unlocking component 4 includes an operating element 41 that is at least partially exposed at the front of the base body 1. Only one operating element 41 is configured so that the user can operate it from both the left and right sides of the car safety seat base to release the lock state of the turntable 2.

[0007] As described above, the child safety seat base can be easily unlocked from either side. The operating element 41 is configured to slide selectively along the left side or along the right side, and the locking state of the turntable 2 can be released by sliding the operating element 41 along the left side or along the right side.

[0008] As described above, a child safety seat base that can be easily unlocked from either side includes a locking mechanism 3 comprising a locking part 31 disposed on a turntable 2 and a locking member 32 movably disposed on the base body 1 for locking and engaging with the locking part 31; the unlocking assembly 4 further includes an unlocking linkage mechanism 42 disposed between the locking member 32 and the operating member 41.

[0009] As described above, a child safety seat base that can be easily unlocked from either side includes an unlocking linkage mechanism 42 comprising a linkage protrusion 421 on a locking member 32 and a linkage drive part 40 on an operating member 41. The linkage protrusion 421 and the linkage drive part 40 are connected and cooperated to cause the operating member 41 to move in conjunction with the locking member 32 and disengage from the locking member 31.

[0010] As described above, a child safety seat base that can be easily unlocked from either side, wherein the locking member 32 is configured to resiliently reset and lock into the locking part 31.

[0011] As described above, a child safety seat base that can be easily unlocked from either side includes a linkage drive unit 40 comprising a first linkage groove 422 and a second linkage groove 423 disposed on an operating member 41. The first linkage groove 422 and the second linkage groove 423 intersect and communicate with each other at one end. The linkage protrusion 421 is restricted to move within the first linkage groove 422 and the second linkage groove 423. When the linkage protrusion 421 is located at the intersection of the first linkage groove 422 and the second linkage groove 423, the locking member 32 locks into the locking part 31.

[0012] As described above, a child safety seat base that can be easily unlocked from either side, wherein the first linkage groove 422 and the second linkage groove 423 are symmetrically arranged.

[0013] As described above, the child safety seat base can be easily unlocked from either side, and the linkage protrusion 421 and the locking member 32 are integrally formed.

[0014] As described above, the child safety seat base can be easily unlocked from either side. The locking mechanism 3 further includes a locking elastic member 33. One end of the locking elastic member 33 elastically abuts against the end of the locking member 32 away from the locking part 31, and the other end of the locking elastic member 33 elastically abuts against the base body 1 or the operating member 41 so that the locking member 32 maintains an elastic reset tendency or resets.

[0015] This utility model also provides a child safety seat, including a child safety seat body and a child safety seat base that can be easily unlocked from either side as described above, wherein the child safety seat body is detachably connected to the child safety seat base.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This utility model configures the operating component so that the user can operate it from both the left and right sides of the car safety seat base to unlock the turntable. That is, regardless of whether the user is on the left or right side of the car safety seat base, they can activate the same operating component to release the locking mechanism and thus unlock the turntable. This not only makes unlocking convenient but also effectively optimizes the unlocking operation structure, reduces manufacturing costs, and makes the overall structure simpler.

[0018] 2. A single operating component is configured to slide on both the left and right sides to release the turntable from its locked state, making it convenient for users to easily unlock and adjust the turntable from outside the doors on either side. Since the user is located outside the rear door when unlocking, they can reach out and slide the operating component on either the left or right side to unlock. The sliding direction of the operating component is more in line with the user's force exertion habits, which is better in terms of ergonomics.

[0019] 3. Furthermore, the device offers two sliding directions that can unlock the door, allowing users to push or pull the device from outside the door regardless of whether they are left- or right-handed. [Attached Image Description]

Detailed Implementation Methods

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figure 1-6 As shown, this utility model discloses a child safety seat base that can be easily unlocked from either side, including a base body 1. A turntable 2 is rotatably connected to the base body 1. A locking mechanism 3 for locking the turntable 2 is provided between the base body 1 and the turntable 2. The base body 1 is also provided with an unlocking component 4 for releasing the locking state between the base body 1 and the turntable 2 by linking the locking mechanism 3. The unlocking component 4 includes an operating element 41 that is at least partially exposed at the front of the base body 1. Only one operating element 41 is configured so that the user can operate it from both the left and right sides of the car safety seat base to release the locked state of the turntable 2. This invention configures the operating component so that the user can operate it from both the left and right sides of the car seat base to unlock the turntable. That is, regardless of whether the user is on the left or right side of the car seat base, they can activate the same operating component to release the locking mechanism and thus unlock the turntable. This not only makes unlocking convenient but also effectively optimizes the unlocking operation structure, reduces manufacturing costs, and makes the overall structure simpler.

[0029] Preferably, the operating element 41 is configured to slide selectively along the left or right side, and sliding the operating element 41 along either the left or right side can release the locking state of the turntable 2. When the user operates the operating element from the left side of the car safety seat base, they can pull the operating element to slide along the left or push the operating element to slide along the right; when the user operates the operating element from the right side of the car safety seat base, they can pull the operating element to slide along the right or push the operating element to slide along the left, satisfying different user operating habits and facilitating force operation.

[0030] like Figure 2-5As shown, for reliable locking and convenient unlocking, the locking mechanism 3 includes a locking part 31 on the turntable 2 and a locking element 32 movably mounted on the base body 1 for locking with the locking part 31; the unlocking assembly 4 also includes an unlocking linkage mechanism 42 between the locking element 32 and the operating element 41. As needed, multiple locking parts 31 can be provided on the turntable 2, that is, locking parts 32 are provided in the forward mode, backward mode and side mode respectively. When the turntable 2 rotates to different modes, it can be locked accordingly.

[0031] like Figure 1-6 As shown, the unlocking linkage mechanism 42 includes a linkage protrusion 421 on the locking member 32 and a linkage drive part 40 on the operating member 41. The linkage protrusion 421 and the linkage drive part 40 are connected and cooperate to cause the operating member 41 to move in conjunction with the locking member 32 and disengage from the locking member 31. During unlocking, the user slides the operating member along the left or right side of the base body. During the sliding process of the operating member, the linkage drive part 40 activates the linkage protrusion 421 to move the locking member 32 relative to the base body away from the locking member until the locking member separates from the locking member, thus releasing the locking state of the turntable.

[0032] like Figure 4 As shown, the locking member 32 is configured to elastically reset and lock into the locking part 31, ensuring that the locking end of the locking member remains locked into the locking part to reliably lock the turntable relative to the base body, ensuring safety and reliability. Preferably, the locking mechanism 3 further includes a locking elastic member 33, one end of which elastically abuts against the end of the locking member 32 away from the locking part 31, and the other end of which elastically abuts against the base body 1 or the operating member 41, so that the locking member 32 maintains an elastic reset tendency or resets. In this utility model, only one set of locking elastic members is needed in conjunction with the unlocking linkage mechanism 42 to drive the locking member 32 and the operating member 41 to reset.

[0033] like Figure 4-6As shown, the linkage drive unit 40 includes a first linkage groove 422 and a second linkage groove 423 disposed on the operating member 41. The first linkage groove 422 and the second linkage groove 423 intersect and communicate with each other at one end. The linkage protrusion 421 is restricted to move within the first linkage groove 422 and the second linkage groove 423. When the linkage protrusion 421 is located at the intersection of the first linkage groove 422 and the second linkage groove 423, the locking member 32 locks into the locking part 31. When the operating member slides along the left or right side, the linkage protrusion 421 slides within the first linkage groove 422 or the second linkage groove 423. Since the linkage protrusion 421 can only move back and forth along the axial direction of the locking member, regardless of whether the operating member slides along the left or right side, the locking member will disengage from the corresponding locking part under the guiding action of the first linkage groove 422 or the second linkage groove 423, thereby unlocking the turntable.

[0034] Among them, the side wall where the linkage protrusion 421 abuts against the intersection of the linkage inclined groove 1 422 and the linkage inclined groove 2 423 adopts a smooth transition to ensure smooth unlocking.

[0035] like Figure 4 , 6 As shown, the first linkage groove 422 and the second linkage groove 423 intersect at one end and are interconnected, forming a herringbone structure. When the operating component is activated, the sliding in the left and right direction is converted into the forward and backward movement of the locking component through the first linkage groove 422 and the second linkage groove 423 of the herringbone structure.

[0036] Preferably, the first linkage inclined groove 422 and the second linkage inclined groove 423 are arranged symmetrically.

[0037] like Figure 5 As shown, in order to improve structural strength and optimize the number of parts, the linkage protrusion 421 and the locking member 32 are integrally formed.

[0038] The base body 1 is provided with a locking groove for guiding the sliding path of the locking member 32. It is not shown in the figure. It can ensure that the locking member 32 slides smoothly and ensures that the locking end of the locking member and the locking part are precisely aligned and engaged, which is convenient for locking.

[0039] like Figure 1 As shown, for ease of operation, the front part of the base body 1 is provided with an operating component groove for guiding the sliding path of the operating component 41. The front part of the base body 1 is also provided with an operating window 11 that communicates with the operating component groove and is used for the user to operate the operating component 41.

[0040] like Figure 1 , 3As shown, for ease of operation, the upper surface of the operating component 41 is provided with an operating recess 411 for user operation, that is, the user's hand acts on the operating recess 411 to move the operating component accordingly.

[0041] This utility model discloses a child safety seat, including a child safety seat body and a child safety seat base that can be easily unlocked from either side as described above. The child safety seat body is detachably connected to the child safety seat base, allowing the user to operate on the left side of the car safety seat base to release the lock of the turntable 2, and also on the right side of the car safety seat base to release the lock of the turntable 2. This not only makes unlocking convenient but also effectively optimizes the unlocking operation structure, reduces manufacturing costs, and makes the overall structure simpler.
