Description

Connecting assembly of child safety seat and child safety seat Technical Field

[0001] The present invention relates to the technical field of children's products, and in particular to a connecting assembly of a child safety seat and the child safety seat. Background Art

[0002] Child safety seats are typically used when children are riding in cars to improve their safety. When in use, the child safety seat is connected to the car seat via a connector assembly. The connector assembly is equipped with a locking mechanism. When the connector assembly is connected to the car seat, the locking mechanism locks the connector assembly and the car seat in place. Once the locking mechanism is unlocked, the child safety seat can be removed from the car seat.

[0003] Most existing child safety seats lack a direct detection mechanism to detect the state of the locking mechanism. Consequently, passengers are unable to detect unlocked mechanisms immediately. This compromises the inherent safety of child safety seats and increases the risk of children riding in vehicles. While some child safety seats incorporate a detection mechanism to monitor the locking mechanism's state, vibrations caused by vehicle turbulence can easily trigger the mechanism inadvertently, misleading the user. Summary of the Invention

[0053] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0054] The child safety seat comprises a seat body and a connecting assembly arranged at the bottom of the seat body, wherein the connecting assembly is used to connect with an anchor provided on a car seat to install the child safety seat on the car seat.

[0055] As shown in FIG. 1 to FIG. 11 , the connection assembly includes a housing 1 , a locking mechanism, an unlocking mechanism, and a detection mechanism.

[0056] The housing 1 extends in the front-to-back direction and has a hollow cavity. The locking mechanism, the unlocking mechanism and the detection mechanism are all arranged in the hollow cavity of the housing 1 .

[0057] The locking mechanism is used to lock the connection assembly relative to the anchors on the car seat. The locking mechanism has a locked and unlocked state. When the child safety seat is installed on the car seat, the connection assembly is connected to the anchors on the car seat, and the locking mechanism is in the locked state, locking the connection assembly and the anchors. When the child safety seat needs to be removed from the car seat, the locking mechanism is unlocked, allowing the connection assembly to be detached from the anchors.

[0058] Specifically, the locking mechanism includes a locking member 2 movably disposed within a hollow cavity of a housing 1. A first locking hook portion 21 having an opening is provided at one end of the locking member 2, and a second locking hook portion 11 having an opening is provided at one end of the housing 1. When the locking mechanism is locked, the locking member 2 is in a locked position, at which point the opening of the second locking hook portion 11 is fully or partially enclosed by the first locking hook portion 21, forming a clamping space for clamping the anchor between the first locking hook portion 21 and the second locking hook portion 11. When the locking mechanism is unlocked, the locking member 2 is in an unlocked position, at which point the first locking hook portion 21 is separated from the opening of the second locking hook portion 11, fully opening the opening of the second locking hook portion 11 and allowing the anchor to be released from the opening of the second locking hook portion 11. In this embodiment, the locking member 2 is rotatably disposed within the hollow cavity of the housing 1, and is transitioned between the locked and unlocked positions by rotating the locking member 2 relative to the housing 1.

[0059] When the locking mechanism is in the locked state, the unlocking mechanism is operated to unlock the locking mechanism. The unlocking mechanism includes an unlocking member 31 and an elastic member 32. The unlocking member 31 is movably disposed within the hollow cavity of the housing 1. One end of the elastic member 32 is connected to the unlocking member 31, and the other end of the elastic member 32 is connected to the locking member 2. In this embodiment, the unlocking member 31 is slidably disposed within the hollow cavity of the housing 1 along the longitudinal extension of the housing 1.

[0060] When the locking mechanism is in the locked state, one end of the unlocking member 31 engages with the locking member 2, and the locking member 2 cannot rotate relative to the housing 1 due to the combined action of the unlocking member 31 and the elastic member 32. When the unlocking member 31 and the locking member 2 are disengaged, the locking member 2 can rotate relative to the housing 1 under the action of the elastic member 32.

[0061] The unlocking member 31 cooperates with the locking member 2 in the following manner: the other end of the locking member 2 is provided with a recess 22. When the locking mechanism is in the locked state, one end of the unlocking member 31 is engaged with the recess 22. Due to the blocking effect of the unlocking member 31, the locking member 2 cannot rotate in the direction that would open the opening of the second lock hook portion 11.

[0062] When the locking mechanism causes the unlocking member 31 to slide in a direction away from the locking member 2 in the locked state, one end of the unlocking member 31 disengages from the recess 22, and the locking member 2 rotates in a direction to open the opening of the second lock hook portion 11 under the action of the elastic member 32, thereby unlocking the locking mechanism.

[0063] The detection mechanism is used to detect the status of the locking mechanism, so that the status of the locking mechanism can be judged based on the detection results of the detection mechanism to avoid the situation where the passengers cannot find out in time after the locking mechanism is unlocked, thereby improving the safety performance of the child safety seat.

[0064] The detection mechanism includes a sensing unit that generates a sensing signal based on the state of the locking mechanism. Specifically, the unlocking member 31 is provided with a mating portion 311 and a non-mating portion 312. The mating portion 311 and the non-mating portion 312 are arranged along the movement direction of the unlocking member 31. The non-mating portion 312 protrudes toward the location of the sensing unit 4 relative to the mating portion 311. The sensing unit 4 includes a trigger portion 41.

[0065] When the locking mechanism is locked, the trigger portion 41 aligns with the mating portion 311, as shown in Figures 4 and 5 . At this point, the mating portion 311 does not act on the trigger portion 41, causing it to remain untriggered and the sensing unit 4 to emit a first sensing signal. Furthermore, a gap is provided between the trigger portion 41 and the mating portion 311. This gap prevents the mating portion 311 from acting on the trigger portion 41, even if vibrations are caused by vehicle jolting. Consequently, the trigger portion 41 is prevented from being erroneously triggered by the vehicle's jolting motion, thereby preventing the sensing unit 4 from emitting an erroneous sensing signal.

[0066] When the unlocking member 31 slides relative to the housing 1 to unlock the locking mechanism, the trigger portion 41 gradually shifts away from the mating portion 311 of the unlocking member 31, and the non-mating portion 312 of the unlocking member 31 is able to abut against the trigger portion 41, thereby acting on the trigger portion 41, as shown in Figures 9 and 10. When the locking mechanism is in the unlocked state, the trigger portion 41 is triggered, and the sensing unit 4 emits a second sensing signal.

[0067] In this embodiment, the sensing unit 4 utilizes a microswitch. As shown in Figures 12 to 15 , the microswitch comprises a body 42 and a button 43. The trigger portion 41 is a spring element connected to the body 42 at one end. The distance between the spring element and the body 42 gradually increases or decreases along the length of the spring element. The button 43 is movably disposed within the body 42, near the end where the spring element connects to the body 42. The button 43 is positioned between the body 42 and the spring element. When the spring element moves toward or away from the body 42, the button 43 is pressed or released.

[0068] When no force is applied to the spring sheet, the spring sheet does not act on the button 43 , so that the button 43 is in a released state. At this time, the micro switch is in an open state, as shown in FIG. 12 and FIG. 13 .

[0069] When force is applied to the spring piece, the other end of the spring piece moves toward the body 42, and the spring piece acts on the button 43, causing the button 43 to move relative to the body 42 and displace until the button 43 has a maximum displacement. At this time, the micro switch is in a closed state, as shown in Figures 14 and 15.

[0070] Specifically, the spring piece includes a main body 411 and a resisting portion 412. One end of the main body 411 is connected to the main body 42. The resisting portion 412 is arranged at the other end of the main body 411 and extends from the connection with the main body 411 in a direction away from the main body 42. The setting position of the button 43 corresponds to the position of the main body 411.

[0071] When the locking mechanism is in the locked state, at least the position of the abutting portion 412 corresponds to the matching portion 311. When the unlocking mechanism slides relative to the housing 1 to unlock the locking mechanism, the abutting portion 412 abuts and matches with the non-matching portion 312.

[0072] When the micro switch is in an open state, there is a distance between the main body 411 and the button 43, or the main body 411 is in contact with the button 43 but does not apply force to the button 43, so that the button 43 is in a released state.

[0073] When the micro switch is in an on state, the distance between the main body 411 and the body 42 gradually increases from one end portion to the other end portion of the main body 411 .

[0074] In this embodiment, the main body 411 is in the shape of a flat plate, and the abutting portion 412 is in the shape of an arc convex away from the main body 42 . The main body 411 and the abutting portion 412 are integrally provided.

[0075] In this embodiment, the engaging portion 311 is a groove provided on the unlocking member 31. When the locking mechanism is in the locked state, the abutting portion 412 of the spring is located in the groove, and there is a gap between the side walls and the bottom of the groove and the spring. This prevents the spring from being affected by external forces, placing the micro switch in the open state and emitting a first sensing signal, as shown in Figures 4 and 5.

[0076] When the unlocking member 31 slides relative to the housing 1 to unlock the locking mechanism, a sidewall of the recess acts on the spring, causing its abutting portion 412 to move toward the body 42. The spring then acts on the button 43, causing it to move relative to the body 42 and displace until the locking mechanism is unlocked. At this point, the abutting portion 412 of the spring is released from the recess, while the non-mating portion 312 of the unlocking member 31 presses against the abutting portion 412 of the spring. The main body 411 of the spring presses against the button 43, causing it to achieve maximum displacement, closing the microswitch and emitting a second sensing signal, as shown in Figures 9 and 10.

[0077] A sidewall of the groove forms an inclined guide surface 311a that connects the mating portion 311 and the non-mating portion 312. This inclined guide surface 311a is inclined from the bottom of the groove toward the top and toward the outside of the groove. In other words, the inclined guide surface 311a is inclined in the direction in which the unlocking member 31 slides when the locking mechanism is unlocked. This facilitates the release of the spring's abutting portion 412 from the groove when the unlocking member 31 slides relative to the housing 1 to unlock the locking mechanism.

[0078] The micro switch has a common pin 44, a normally closed pin 45 and a normally open pin 46. The common pin 44 and the normally closed pin 45 are respectively connected to a conductive wire 47, that is, the micro switch of this embodiment is in a normally closed state, avoiding the risk of unstable output signal when the car is bumpy.

[0079] The detection mechanism also includes a control unit and a display unit. The sensing unit 4 and the display unit are each electrically connected to the control unit. The control unit receives the sensing signal emitted by the sensing unit 4 and controls the display unit to display different information based on the sensing signal. The user can intuitively determine the status of the locking mechanism based on the information displayed on the display unit.

[0080] The display unit may be a lighting device. When the sensing unit 4 sends a first sensing signal, the control unit controls the lighting device to be turned on. When the sensing unit 4 sends a second sensing signal, the control unit controls the lighting device to be turned off.

[0081] The display unit is not limited to a lighting device, and may also be other devices such as a signal light.

[0082] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made in accordance with the spirit of the present invention are intended to be covered by the scope of protection of the present invention.
