Detailed Description

Fig. 1 to 4 show views of a child safety seat 100 according to an embodiment of the present invention, the child safety seat 100 including a support assembly 1A (hereinafter, simply referred to as a support assembly 1A) of the child safety seat 100 provided according to the embodiment of the present invention and a seat body 2A of the child safety seat 100 provided according to the embodiment of the present invention, and the support assembly 1A and the seat body 2A will be described together.

Referring to fig. 2, the child safety seat 100 includes a base 11, and the support assembly 1A is adapted to the base 11. The base 11 is intended to be placed on a vehicle seat (not shown) and is intended to mount the seat body 2A of the child safety seat 100. In some embodiments, the base 11 may be fixedly coupled with the seat body 2A. In some embodiments, the base 11 may be rotatably connected with the seat body 2A. In some embodiments, the base 11 and the seat body 2A are detachably connected.

The support assembly 1A includes at least one support leg bracket 111. Each support leg bracket 111 is connected to the base 11 and is disposed, for example, near the front end of the base 11. The support assembly 1A may further comprise a support leg 16, the support leg 16 being adapted to be mounted to a support leg bracket 111, the lower end of the support leg 16 being adapted to abut the floor of the vehicle interior. The base 11 may include a rearwardly disposed abutment bracket 112, the abutment bracket 112 being inclined relative to the underside of the base 11 for abutment with the back of a vehicle seat. The rear end of base 11 may also be fitted with an ISOFIX plug 118 to snap fit with an ISOFIX socket of a vehicle seat.

It should be noted that, unless otherwise specified, the directional terms such as "front", "rear", "left", "right", "up", "down", etc. in the present embodiment correspond to the directions of "front", "rear", "left", "right", "up", "down", etc. of the vehicle, and these directional terms are only used to make the description of the embodiments of the present invention clearer, and are not used to unduly limit the scope of the present invention.

In the embodiment in which the base 11 is rotatably connected to the seat body 2A, the seat body 2A may be mounted on the base 11 in the forward direction or in the reverse direction, and fig. 1 is a perspective view showing the seat body 2A mounted on the base 11 in the reverse direction, it being understood that the face of the child seated on the seat body 2A mounted in the reverse direction faces rearward.

Referring to fig. 1, 6 to 8, in some embodiments, the base 11 may include a base frame 11a and a supporting seat 11b, and the base frame 11a may be made of metal pipes and plates, but the invention is not limited thereto, and other materials such as plastic, plastic steel or alloy type materials are also within the scope of the invention. The support seat 11b may be made of, for example, hard plastic. The reclining bracket 112 and the support leg bracket 111 may be connected to the bottom frame 11a. The support seat 11b is disposed at a middle portion of the base frame 11a for relatively rotatably connecting with the seat body 2A. That is, the support seat 11b functions as a turn table and has a rotation center R-R about which the seat body 2A can rotate. In addition, the support seat 11b may have a first lock structure 110 (see fig. 8) for restricting the rotational position of the seat body 2A, and a second lock structure 23 (see fig. 11) for restricting the rotational position of the seat body 2A may be provided on the seat body 2A, and the rotational position of the seat body 2A may be locked or unlocked by engaging or disengaging the first lock structure 110 and the second lock structure 23. The first locking structure 110 and the second locking structure 23 may cooperate to constitute a locking device for locking the rotational position of the seat body 2A, examples of which will be described in detail below.

With combined reference to fig. 2 to 4 and fig. 6 and 7, in some embodiments, the support leg bracket 111 extends obliquely upward with respect to the bottom surface of the base 11, and the support leg bracket 111 may be provided with an abutting member 12 for abutting against the housing 21 of the seat body 2A. The support leg bracket 111 may extend forward and upward relative to the bottom surface of the base 11 so as to be in abutting contact with the casing 21 of the seat body 2A and to be engaged with the support leg 16. In some embodiments, the support leg bracket 111 is, for example, arcuate or has another suitable shape. As will be appreciated in the art, the seat body 2A typically has a relatively rigid shell 21, and the interior compartment of the shell 21 is provided with a resilient padding, the surface of which for contact with the body of a child is typically covered by fabric. Referring to fig. 3, when the vehicle is suddenly braked by accident, the seat body 2A is tilted forward in the direction of the arrow F by the inertial force, and the movement of the support leg bracket 111 is restricted by the support leg 16, so that the abutting member 12 can be abutted tightly against the housing 21. At this time, the support leg 16 indirectly supports the housing 21 of the seat body 2A through the support leg bracket 111 and the abutting member 12, the forward tilting movement of the seat body 2A can be effectively prevented, so that the child in the seat body 2A can be better protected.

Referring to fig. 6-9, in some embodiments, the connection location of the support leg 16 and the support leg bracket 111 is adjacent to the abutment member 12, which facilitates the support force of the support leg 16 to be transmitted to the abutment member 12 in a short distance, providing a good auxiliary support effect for the housing 21. For example, the support leg 16 may be connected to the upper end of the support leg bracket 111, and the abutting member 12 may be provided to the upper end of the support leg bracket 111.

Referring again to fig. 1, 2, 6 and 7, in some embodiments, the base 11 of the support assembly 1A may be configured with two support leg brackets 111, the two support leg brackets 111 being arranged substantially symmetrically about a longitudinal center plane S of the base 11, the two support leg brackets 111 being mounted with the abutment members 12, respectively. For example, the abutting members 12 are respectively mounted to the upper ends of the corresponding support leg brackets 111. In some embodiments, to further optimize the structure, the support leg 16 may include a leg 161 and a beam 162 at the upper end of the leg 161, the upper end of the leg 161 being connected to the middle of the beam 162. The cross member 162 may be pivotally connected at both ends to the upper ends of the two support leg legs 111. The legs 161 are welded together or integrally formed with the beam 162, for example, and the legs 161 are retractable legs, for example. Thus, the support legs 16 can be in a normal use state by adjusting the length and the pivoting angle of the support legs 16, thereby effectively preventing the forward tilting of the child safety seat. Of course, in other embodiments, the leg 161 may be a fixed length leg.

In some embodiments, the abutting element 12 can be made of a cushioning material that can provide cushioning, so that the abutting element 12 has shock absorbing function. For example, the abutment element 12 may be made of hytrel (marine), TPE (thermoplastic elastomer), or any other suitable material. In some embodiments, the contact surface of the abutting element 12 for contacting the shell 21 of the seat body 2A may be provided with a plurality of first protrusions 121, the first protrusions 121 for increasing the frictional force between the abutting element 12 and the shell 21. In some embodiments, the shape of the contact surface of the abutment element 12 is adapted to the surface shape of the housing 21.

Referring again to fig. 2 and 3, in some embodiments, the seat body 2A is rotatably mounted on the base 11, and the housing 21 of the seat body 2A has at least one pressing portion 22 thereon, and each pressing portion 22 is used for pressing against the pressing element 12 on the supporting leg bracket 111. It will be appreciated that the portion of the housing 21 which is intended to abut against the abutment member 12 will be subjected to a relatively large pressure when the vehicle is suddenly braked. In this way, the pressing portion 22 may be a structure provided on the housing 21 specifically corresponding to the pressing member 12 to locally enhance the structural strength of the housing 21 and avoid the housing 21 from being broken when receiving a sudden increase of the pressing force from the pressing member 12.

It is understood that the seat body 2A is fixed to the vehicle seat in a forward-mounting or reverse-mounting manner in the normal use state. Therefore, in some not-shown embodiments, a pressing portion may be provided on the housing 21 of the seat portion 21a of the seat body 2A to accommodate a situation in which the seat body 2A is fixed to the vehicle seat in a positively-mounted manner. Referring to fig. 2, in some embodiments, pressing parts 22 may be provided on the shell 21 of the backrest part 21b of the seat body 2A, the pressing parts 22 being provided in one-to-one correspondence with the pressing elements 12, for example, to accommodate a case where the child safety seat is fixed to the vehicle seat in a reverse-installation manner.

In some embodiments, the contact surface of the pressing portion 22 for contacting the abutting member 12 is provided with a plurality of second protrusions 221, and the plurality of second protrusions 221 are used for increasing the friction force between the pressing portion 22 and the abutting member 12. In some embodiments, the first protrusion 121 and the second protrusion 221 may be engaged, for example, in a concavo-convex fit manner to more favorably restrict the forward tilting movement of the seat body 2A at the time of sudden braking of the vehicle.

An exemplary embodiment of the pressing portion 22, the first protrusion 121, and the second protrusion 221 is shown in the present embodiment. Referring to fig. 5 and 8 in combination, each first protrusion 121 extends laterally on the corresponding abutting member 12, respectively, and the plurality of first protrusions 121 are arranged sequentially in the longitudinal direction (the direction indicated by arrow H) along the contact surface of the abutting member 12. The cross section of each first protrusion 121 may be circular arc, trapezoidal, triangular, rectangular, or the like. Referring to fig. 2 and 5 in combination, each pressing portion 22 extends along the surface of the housing 21 in a generally longitudinal direction, each second protrusion 221 extends laterally on the corresponding pressing portion 22, and the plurality of second protrusions 221 are arranged sequentially in the longitudinal direction along the contact surface of the pressing portion 22. In some embodiments, the cross-section of each second protrusion 221 may be circular arc, trapezoidal, triangular, rectangular, or the like.

Referring to fig. 5, in some embodiments, the cross-section of the first plurality of protrusions 121 may have a continuous first undulation or first tooth shape or other suitable shape, and the cross-section of the second plurality of protrusions 221 may have a continuous second undulation or second tooth shape or other suitable shape. In this way, the plurality of first protrusions 121 and the plurality of second protrusions 221 may be engaged in a fitting manner with each other, and when the vehicle is suddenly braked, the plurality of first protrusions 121 and the plurality of second protrusions 221 rub against each other, and may function to buffer and restrict forward tilting of the housing 21.

Referring again to fig. 2 and 3, in some embodiments, the pressure portion 22 is located at the outer shell 21 of the backrest portion 21b, and the outer shell 21 of the backrest portion 21b may be formed with a limit recess 210 above the pressure portion 22. For example, when the housing 21 is tilted forward to a certain position in the direction of the arrow F due to sudden braking of the vehicle, further forward tilting movement of the housing 21 can be effectively restricted by engagement of the stopper recess 210 and the abutting member 12, thereby ensuring seating safety of a child in the seat body 2A. In some embodiments, the press section 22 smoothly transitions into the retaining recess 210.

With combined reference to fig. 1 and 8, in some embodiments, the contact surfaces of the abutment elements 12 on the two support leg brackets 111 for abutting contact with the abutment 22 of the housing 21 are both inclined with respect to the longitudinal center plane S. In this way, when the two abutting elements 12 abut against the abutting portion 22 of the housing 21, since the plurality of second protruding portions 221 and the plurality of second protruding portions 221 all extend laterally, the seat body 2A can still move left and right when receiving a torque force, so that a user can still conveniently adjust the installation direction of the seat body 2A as required.

Referring to fig. 6, in some embodiments, an angle limiting device for limiting the pivoting angle of the supporting leg 16 is provided between the base 11 and the supporting leg 16, and the angle limiting device is effective to prevent the supporting leg 16 from being undesirably pivoted in a use state to cause the support failure of the supporting leg 16. The angle limiting device can be used in various embodiments, for example, in some embodiments, the angle limiting device can include a webbing 131 capable of being tensioned, two ends of the webbing 131 are respectively connected with the base 11, the middle part of the webbing 131 is wound around the middle part of the supporting leg 16, and the webbing 131 can be tensioned by adjusting the length of the webbing 131. In some embodiments, to facilitate installation of the webbing 131, two hook bodies 103 may be provided on the base 11, and both ends of the webbing 131 may be respectively hooked on the hook bodies 103. In some embodiments, the middle portion of the leg portion 161 of the support leg 16 may be provided with a catch 160 for receiving the webbing 131 to prevent the webbing 131 from undesirably sliding along the leg portion 161 of the support leg 16 to affect the tensioning effect of the webbing 131.

Referring to fig. 6, 7 and 9, in some embodiments, both ends of the cross member 162 at the upper end of the support leg 16 and the upper ends of the two support leg brackets 111 are connected by the connectors 14, respectively. The upper ends of the support leg brackets 111 are pivotally connected to the corresponding connecting members 14 through first pins 141, the two ends of the cross beam 162 are pivotally connected to the connecting members 14 through second pins 142, and the first pins 141 and the second pins 142 are parallel to each other. Thus, in the non-use condition, the support legs 16 can be folded towards the base 11 to reduce the volume, thereby facilitating transportation.

Referring collectively to fig. 8, 11 and 12, exemplary embodiments of the first and

second locking structures

110 and 23 are shown. The first latch structure 110 is, for example, a latch hole formed in the support base 11b, and it is understood that the second latch structure 23 correspondingly includes a retractable latch pin 233, and the rotatable seat body 2A can be latched, for example, in a state of being forwardly mounted on the vehicle seat or in a state of being reversely mounted on the vehicle seat by operating the latch pin 233 to extend the latch pin 233 into the latch hole. When the lock pin 233 is withdrawn from the lock hole, the seat body 2A can be rotated about the rotation center R-R to change its position.

In some embodiments, referring again to fig. 11 and 12, the second latch structure 23 may include a button 231, a resilient element 232, and the latch 233 described above. The button 231 can be pressed to have a locked position and an unlocked position on its moving path. The elastic member 232 serves to hold the button 231 in the locking position. The lock pin 233 is operatively connected to the button 231 to be able to lock or unlock the seat body 2A. For example, when the push button 231 receives a pressing force, the push button 231 moves from the lock position to the unlock position, and the lock pin 233 is driven to retreat from the lock hole to unlock the seat body 2A. When the pressing force applied to the push button 231 is removed, the push button 231 is automatically moved from the unlock position to the lock position by the elastic member 232, and the lock pin 233 can be driven to extend into the lock hole to lock the seat body 2A.

Referring to fig. 10-12, in some embodiments, the seat body 2A may include a latch anchor 24, the latch anchor 24 being fixedly connected to the seat body 2A, for example. The locking pin holder 24 may be provided with a sleeve 241, an axial direction of the sleeve 241 is substantially perpendicular to the moving direction M of the button 231, and a hole wall of the sleeve 241 is provided with a first guide hole 2410 extending axially. The latch 233 is slidably received in the sleeve 241, and the latch 233 has a first guide post 2331 extending from a first guide hole 2410. The button 231 may be provided with a second guide hole 2312, the second guide hole 2312 extending obliquely with respect to the moving direction M of the button 231, the angle of inclination of the second guide hole 2312 being related to the stroke of the button 231. The first guide post 2331 of the latch 233 extends into the second guide hole 2312 and is slidably engaged with the second guide hole 2312. When the button 231 is switched between the locking position and the unlocking position, the lock pin 233 is slidably extended or retracted along the sleeve 241 to lock the seat body 2A or unlock the seat body 2A by the engagement of the first guide column 2331 with the first guide hole 2410 and the second guide hole 2312.

In some embodiments, the button 231 may have a receiving recess 2310 for receiving the sleeve 241, and the elastic member 232 may be a spring and installed between a sidewall 2312 of the receiving recess 2310 and an outer wall of the sleeve 241. For example, a boss 243 may be disposed on an outer wall of the sleeve 241 for fitting in a first end of the spring, and a boss (not shown) may be disposed on the side wall 2312 for fitting in a second end of the spring, and both bosses may be used to position the spring.

In some embodiments, the button 231 may further be provided with a third guiding hole 2313, an extending direction of the third guiding hole 2313 is parallel to the moving direction M of the button 231, the locking pin holder 24 is provided with a protrusion 242 extending into the third guiding hole 2313, and the protrusion 242 is slidably engaged with the third guiding hole 2313 for guiding the movement of the button 231.

It should be noted that, although the abutting element 12 is described as being disposed on the support leg bracket 111 in the above-described embodiment, in some embodiments, which are not shown, the abutting element 12 may be disposed on the support leg 16. For example, the support leg bracket 111 may not be inclined upward, the middle portion of the support leg 16 is connected to the support leg bracket 111, for example, by the cross member 162, the upper end of the support leg 16 is made to be close to the pressing portion 22 of the housing 21, and the abutting member 12 is provided at the upper end of the support leg 16 for abutting against the pressing portion 22 of the housing 21, so that the support leg 16 can directly support the pressing portion 22 of the housing 21 by the abutting member 12.
