DETAILED DESCRIPTION OF THE EMBODIMENTS [0022] FIGS. 1 to 4 illustrate views of a child safety seat 100 according to embodiments of the present application. The child safety seat 100 includes a support assembly lAof the child safety seat 100 (hereinafter simply referred to the support assembly 1A) according to the embodiment of the present application and a seat body 2 A of the child safety seat 100 according to the embodiment of the present application. The support assembly 1A and the seat body 2A will be described herein. [0023] Referring to FIG. 2, the child safety seat 100 includes a base 11, and the support assembly lAis adapted for the base 11. The base 11 is configured to be placed on a vehicle seat (not shown in figures) and to mount the seat body 2A of the child safety seat 100. In some embodiments, the base
II is fixedly connected to the seat body 2A. In some embodiments, the base 11 is rotatably connected to the seat body 2A. In some embodiments, the base 11 is detachably connected to the seat body 2A. [0024] The support assembly 1 A includes at least one load leg bracket 111. Each load leg bracket
III is connected to the base 11, and is disposed, for example, proximate to a front end of the base 11. The support assembly 1 A further includes a load leg 16 mounted on the load leg bracket 111. A lower end of the load leg 16 is configured to abut against a floor of a vehicle. The base 11 includes a rebound bracket 112 arranged backwards. The rebound bracket 112 is inclined upwards and backwards with respect to a bottom surface of the base 11, so as to abutting against a backrest of the vehicle seat. A rear end of the base 11 is further provided with an ISOFIX plug 118 to engage with an ISOFIX socket of the vehicle seat.
[0025] It should be noted that, unless otherwise expressly specified, the orientation terms such as "front", "rear", "left", "right", "upper" and "lower" in the embodiments correspond to the "front" "rear", "left", "right", "upper", and "lower" directions of the vehicle. These orientation terms are only used to make the description of the embodiments of the present application clearer, but are not intended to improperly limit the protection scope of the present application.
[0026] In the embodiments in which the base 11 is rotatably connected to the seat body 2 A, the seat body 2Ais mounted on the base 11 to face forward or backward. FIG. 1 shows a perspective view of the seat body 2A mounted on the base 11 and facing backward. It may be understood that the child, sitting in the mounted seat body 2 A facing backward, faces backwards.
[0027] Referring to FIG. 1, and FIGS. 6 to 8, in some embodiments, the base 11 includes a base frame 11a and a supporting base lib. The base frame 11a is mainly made of metal tubing and plates, but is not limited to these materials in the present application. For example, the base frame 11a is made of plastics, glass-reinforced plastics or alloys, which is also within the protection scope of the present application. For example, the supporting base lib is made of rigid plastic. The rebound bracket 112 and the load leg bracket 111 are connected to the bottom frame 11a, respectively. The supporting base lib is arranged on the central portion of the base frame 11a, and is connected to the seat body 2A relatively rotatably. That is, the supporting base lib functions as a turntable, and has a rotation center R-R around which the seat body 2A can rotate. In addition, the supporting base lib has a first locking structure 110 (see FIG. 8) for restricting the rotation position of the seat body 2 A. A second locking structure 23 (see FIG. 11) is arranged on the seat body 2 A to restrict the rotation position of the seat body 2A. The rotation position of the seat body 2A is locked or unlocked by the first locking structure 110 engaging with or disengaging from the second locking structure 23. The first locking structure 110 engages with the second locking structure 23 to form a locking device for locking the rotation position of the seat body 2 A. Examples of the first locking structure 110 and the second locking structure 23 will be described in detail below.
[0028] Referring to FIGS. 2 to 4, FIG. 6, and FIG. 7, in some embodiments, the load leg bracket 111 extends obliquely upward with respect to the bottom surface of the base 11. The load leg bracket 111 is provided with an abutting element 12 configured to abut against a housing 21 of the seat body 2A. The load leg bracket 111 extends forward and upward relative to the bottom surface of the base 11, so as to abut against the housing 21 of the seat body 2A and to engage with the load leg 16. In some embodiments, the load leg bracket 111, for example, is in an arc shape, or has any other suitable shape. As known from the related art, the seat body 2 A usually has a relatively rigid housing 21, and an inner cavity of the housing 21 is filled with elastic fillers, and surfaces of the fillers in contact with the body of the child are usually covered with fabrics. Referring to FIG. 3, when the vehicle is braked suddenly due to an accident, the seat body 2 A will tip forward in a direction indicated by an arrow F under the action of the inertial force, and the movement of the load leg bracket 111 is restricted by the load leg 16, so the abutting element 12 can tightly abut against the housing 21. In this case, the load leg 16 indirectly supports the housing 21 of the seat body 2 A through the load leg bracket 111 and the abutting element 12, thereby effectively preventing the seat body 2 A from tilting forward, and better protecting the child in the seat body 2A.
[0029] Referring to FIGS. 6 to 9, in some embodiments, the connection position of the load leg 16 and the load leg bracket 111 is adjacent to the abutting element 12, which is beneficial to transmission of the supporting force of the load leg 16 to the abutting element 12 in a short distance, thereby providing a good auxiliary support effect for the housing 21. For example, the load leg 16 is connected to an upper end of the load leg bracket 111, and the abutting element 12 is arranged on the upper end of the load leg bracket 111.
[0030] Referring to FIGS. 1, 2, 6 and 7, in some embodiments, the base 11 of the support assembly 1A is provided with two load leg brackets 111. The two load leg brackets 111 are arranged substantially symmetrically with respect to the longitudinal center plane S of the base 11. The two load leg brackets 111 each are provided with the abutting element 12. For example, the abutting elements 12 are mounted on the upper ends of the corresponding load leg brackets 111, respectively. In some embodiments, in order to further optimize the structure, the load leg 16 includes a leg 161 and a crossbeam 162 disposed at an upper end of the leg 161. The upper end of the leg 161 is connected to the middle of the crossbeam 162. Two ends of the crossbeam 162 are pivotally connected to the upper ends of the two load leg brackets 111, respectively. The leg 161 and the crossbeam 162 are welded together or integrally formed, for example. For example, the leg 161 is a retractable leg. In this way, by adjusting a length and a pivoting angle of the load leg 16, the load leg 16 may be in a normal state of use, thereby effectively preventing the child safety seat from tilting forward. Certainly, in other embodiments, the leg 161 may also has a constant length.
[0031] In some embodiments, the abutting element 12 is made of a cushioning material capable of cushioning, so that the abutting element 12 also has a shock-absorbing function. For example, the abutting element 12 is made of hytrel, thermoplastic elastomer (TPE), or any other suitable material. In some embodiments, a contact surface of the abutting element 12 in contact with the housing 21 of the seat body 2A is provided with a plurality of first protrusions 121. The first protrusions 121 are configured to increase the friction force between the abutting element 12 and the housing 21. In some embodiments, the shape of the contact surface of the abutting element 12 is adapted to the surface shape of the housing 21.
[0032] Referring to FIGS. 2 and 3, in some embodiments, the seat body 2Ais rotatably mounted on the base 11. The housing 21 of the seat body 2A has at least one abutting portion 22. Each abutting portion 22 is configured to abut against a corresponding abutting element 12 on the load leg bracket 111. It may be understood that, when the vehicle is suddenly braked, the pressure exerted on the portion of the housing 21 configured to abut against the abutting element 12 will be relatively large. In this way, the abutting portion 22 is a structure corresponding to the abutting element 12 and specially provided on the housing 21, to locally enhance the structural strength of the housing 21 and prevent the housing 21 from breaking when the housing 21 receives a suddenly increased pressure from the abutting element 12.
[0033] In a normal use state, the seat body 2A is fixed on the vehicle seat in the installation mode of facing forward or facing backward. Therefore, in some embodiments unillustrated, the abutting portion is arranged on part of the housing 21 at the seat portion 21a of the seat body 2A, so as to be adapted for the seat body 2A fixed on the vehicle seat in the installation mode of facing forward. Referring to FIG. 2, in some embodiments, the abutting portion 22 is arranged on part of the housing 21 at the backrest portion 21b of the seat body 2A. For example, the abutting portions 22 are arranged in a one-to-one correspondence with the abutting elements 12, so as to be adapted for the child safety seat fixed on the vehicle seat in the installation mode of facing backward.
[0034] In some embodiments, the contact surface of the abutting portion 22 in contact with the abutting element 12 is provided with a plurality of second protrusions 221. The plurality of second protrusions 221 are configured to increase the friction force between the abutting portion 22 and the abutting element 12. In some embodiments, the first protruding portion 121 and the second protruding portion 221 engage with each other, for example, by means of a concave-convex engagement, thus better preventing the seat body 2 A from tilting forward when the vehicle is suddenly braked.
[0035] Exemplary implementations of the abutting portion 22, the first protruding portion 121 and the second protruding portion 221 are illustrated in this embodiment. Referring to FIGS. 5 and 8, each first protrusion 121 on the corresponding abutting element 12 extends laterally. The plurality of first protrusions 121 are sequentially arranged in a longitudinal direction (a direction indicated by an arrow H shown in FIG. 3) on the contact surface of the abutting element 12. The cross section of each of the first protrusions 121 is in a circular arc shape, a trapezoid shape, a triangle shape, a rectangle shape, or the like. Referring to FIGS. 2 and 5, each abutting portion 22 substantially extends along the surface of the housing 21 in the longitudinal direction, and each second protruding portion 221 on the corresponding abutting portion 22 extends laterally. The plurality of second protruding portions 221 are sequentially arranged in the longitudinal direction on the contact surface of the abutting portion 22. In some embodiments, the cross section of each of the second protrusions 221 is in a circular arc shape, a trapezoid shape, a triangle shape, a rectangle shape, or the like.
[0036] Referring to FIG. 5, in some embodiments, the cross sections of the plurality of first protrusions 121 are in a continuous first wave shape, or in a first teeth shape, or in any other suitable shape, and the cross sections of the plurality of second protrusions 221 are in a continuous second wave shape, or in a second teeth shape, or in any other suitable shape. In this way, the plurality of first protrusions 121 and the plurality of second protrusions 221 may engage with each other by fitting each other. When the vehicle is suddenly braked, the plurality of first protrusions 121 and the plurality of second protrusions 221 rub against each other, thus playing the role of cushioning and preventing the housing 21 from tilting forward.
[0037] Referring to FIGS. 2 and 3 again, in some embodiments, the abutting portion 22 is located at part of the housing 21 at the backrest portion 21b. A limiting recess 210 is defined on the housing 21 of the backrest portion 21b and located above the abutting portion 22. For example, when the sudden braking of the vehicle causes the housing 21 to tilt forward to a certain position along the direction indicated by the arrow F, the limiting recess 210 engages with the abutting element 12, which may effectively prevent the housing 21 from further tilting forward, thereby ensuring the safety of the child seated in the seat body 2A. In some embodiments, the abutting portion 22 smoothly transitions to the limiting recess 210.
[0038] Referring to FIGS. 1 and 8, in some embodiments, the contact surfaces of the abutting elements 12 on the two load leg brackets 111, which are in contact with and abut against the abutting portions 22 of the housing 21, are both inclined with respect to the longitudinal center plane S. In this way, when two abutting elements 12 abut against the abutting portions 22 of the housing 21, respectively, since the plurality of first protrusions 121 and the plurality of second protrusions 221 all extend laterally, the seat body 2 A, when receiving the torque force, can still move to the left or the right, so that a user can still conveniently adjust the mounting direction of the seat body 2A as required. [0039] Referring to FIG. 6, in some embodiments, an angle limiting device for limiting the pivoting angle of the load leg 16 is disposed between the base 11 and the load leg 16. The angle limiting device effectively prevents the load leg 16 in use from pivoting unexpectedly and causing a supporting failure of the load leg 16. The angle limiting device can be implemented in various ways. For example, in some embodiments, the angle limiting device includes a fabric belt 131 that can be tensioned. Two ends of the fabric belt 131 are connected to the base 11, respectively. The middle portion of the fabric belt 131 is wrapped over the middle portion of the load leg 16. The fabric belt 131 may be tensioned by adjusting the length of the fabric belt 131 itself. In some embodiments, in order to facilitate the installation of the fabric belt 131, two hook bodies 103 are arranged on the base 11. Two ends of the fabric belt 131 are hooked on the hook bodies 103, respectively. In some embodiments, the middle portion of the leg 161 of the load leg 16 has a receiving groove 160 for receiving the fabric belt 131, to prevent the fabric belt 131 from sliding along the leg 161 of the load leg 16 unexpectedly and affecting the tension effect of the fabric belt 131.
[0040] Referring to FIGS. 6, 7 and 9, in some embodiments, two ends of the crossbeam 162 on the upper end of the load leg 16 are connected to the upper ends of the two load leg brackets 111 through connecting members 14, respectively. The upper end of each load leg bracket 111 is pivotally connected to the corresponding connecting member 14 through a second pin shaft 142. Two ends of the crossbeam 162 are pivotally connected to the connecting members 14 through first pin shafts 141, respectively. The first pin shafts 141 and the second pin shafts 142 are parallel to each other. In this way, in a non-use state, the load leg 16 may be folded toward the base 11, thus reducing the volume and facilitating transportation.
[0041] In conjunction with reference to FIGS. 8, 11 and 12, exemplary implementations of the first locking structure 110 and the second locking structure 23 are illustrated. The first locking structure 110 is, for example, a locking hole formed on the supporting base lib. The second locking structure 23 correspondingly includes a retractable locking pin 233. The locking pin 233 may be operated to be inserted into the lock hole, so that the rotatable seat body 2A may be locked on the vehicle seat and mounted to be, for example, in a state of facing forward or in a state of facing backward. When the locking pin 233 is withdrawn from the locking hole, the seat body 2A may be rotated around the rotation center R-R to change its position.
[0042] In some embodiments, referring to FIGS. 11 and 12, the second locking structure 23 includes a button 231, an elastic element 232 and the locking pin 233. The button 231 may be pressed to have a locking position and an unlocking position on its motion path. The elastic element 232 is configured to keep the button 231 in the locking position. The locking pin 233 is operably connected to the button 231 to enable the seat body 2 A to be locked or unlocked. For example, when the button 231 is pressed, the button 231 moves from the locking position to the unlocking position, thus driving the locking pin 233 to withdraw from the locking hole to unlock the seat body 2 A. When the pressing force exerted on the button 231 is removed, the button 231 automatically moves from the unlocking position to the locking position under the action of the elastic element 232, while driving the locking pin 233 to extend into the locking hole to lock the seat body 2A.
[0043] Referring to FIGS. 11 and 12, in some embodiments, the seat body 2A includes a locking pin fixing base 24. For example, the locking pin fixing base 24 is fixedly connected to the seat body 2A. The locking pin fixing base 24 is provided with a sleeve 241. An axial direction of the sleeve 241 is substantially perpendicular to a moving direction M of the button 231, and a wall of the sleeve 241 has a first guiding hole 2410 that extends in the axial direction. The locking pin 233 is slidably sleeved in the sleeve 241, and the locking pin 233 has a first guiding post 2331 extending from the first guiding hole 2410. The button 231 has a second guiding hole 2312. The second guiding hole 2312 extends obliquely with respect to the moving direction M of the button 231. The inclination angle of the second guiding hole 2312 is related to a stroke of the button 231. The first guiding post 2331 of the locking pin 233 extends into the second guiding hole 2312 and slidably engages with the second guiding hole 2312. When the button 231 is switched between the locking position and the unlocking position, the locking pin 233 may slidably extend out or retract along the sleeve 241 by means of the engagement of the first guiding post 2331 with the first guiding hole 2410 and with the second guiding hole 2312, to lock the seat body 2 A or unlock the seat body 2 A.
[0044] In some embodiments, the button 231 has a receiving recess 2310 for receiving the sleeve 241. The elastic element 232 is a spring and is mounted between a side wall 2311 of the receiving recess 2310 and an outer wall of the sleeve 241. For example, the outer wall of the sleeve 241 is provided with a protruding post 243 sleeved in the first end of the spring. The sidewall 2311 is provided with a protruding post (not shown in the figures) sleeved in the second end of the spring. The two protruding posts are configured to position the spring.
[0045] In some embodiments, the button 231 also has 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 fixing base 24 has a protruding block 242 extending into the third guiding hole 2313. The protruding block 242 slidably engages with the third guiding hole 2313 to guide the movement of the button 231.
[0046] It should be noted that, although the abutting element 12 in the above-mentioned embodiments is described as being arranged on the load leg bracket 111 as an example, in some unillustrated embodiments, the abutting element 12 may also be arranged on the load leg 16. For example, the load leg bracket 111 may not be inclined upward. The middle portion of the load leg 16 is connected to the load leg bracket 111, for example by means of the crossbeam 162, so that the upper end of the load leg 16 approaches the abutting portion 22 of the housing 21. The abutting element 12 is arranged on the upper end of the load leg 16, so as to abut against the abutting portion 22 of the housing 21, so that the load leg 16 may directly support the abutting portion 22 of the housing 21 through the abutting element 12. In the case of no conflict, the features of the abutting element 12 and the abutting portion 22 may refer to the examples in the above embodiments. For example, the abutting element 12 may be made of a cushioning material capable of cushioning. Exemplarily, the middle portion of the load leg 16 is pivotally connected to the load leg bracket 111, and the upper end of the load leg 16 may extend or retract with respect to the extending direction of the load leg 16. In this case, the extended state or the retracted state of the upper end of the load leg 16 may be freely selected, so that the abutting element 12 may assist in supporting the housing 21 or not. [0047] The technical features of the embodiments above may be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features of the above embodiments are described.
