Description

[Technical Field]

[0001] The present disclosure relates to a joint structure and a child car seat including the joint structure. [Background technology]

[0002] A child car seat is a common device that can be used to seat children or infants of different ages. Child car seats are designed for the safety of children in automobiles or other vehicles, and can restrain children from dangerous behavior while in a moving automobile and protect children from injury in the event of a sudden automobile collision or other accident. Summary of the Invention [Problem to be solved by the invention]

[0003] Conventional child car seats usually do not have a canopy, which is disadvantageous for use in convertible cars or outdoors, etc. Even if a child car seat has a canopy, it is usually designed to be fixedly attached to the seat, making it inconvenient to remove the canopy.

[0004] BACKGROUND OF THE INVENTION Folding strollers, car seats and other child carriers are increasingly being equipped with canopy mechanisms to provide shade, wind protection and privacy. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0007] While the present specification illustrates and describes the present invention with reference to specific embodiments, the present disclosure should not be limited thereto. More specifically, various modifications can be made to the aspects disclosed in these detailed descriptions within the scope of the equivalent solutions set forth in the claims and without departing from the present disclosure.

[0008] The directional terms used in the specification, such as "front," "rear," "upper," and "lower," are merely for ease of understanding. The present disclosure is not limited to these directional terms and can be adjusted according to actual circumstances. Although the present invention will be described with reference to exemplary embodiments, the terms used are for explanation and illustration only, and not for limitation.

[0009] First, an overall description of a child car seat according to one embodiment of the present invention will be given with reference to Figures 1 to 3. As shown, the child car seat includes a seat body 300 having a case 301, a headrest 302, a backrest 303, and a seat 304. In this embodiment, an opening and storage space 305 are disposed on both sides of the seat body 300 (see Figure 4A). The opening and storage space 305 are located on the case 301 at a position opposite the upper edge of the headrest 302. In some other embodiments, the opening and storage space 305 may be located on the case 301 at a position corresponding to a position between the upper edge of the headrest 302 and the upper edge of the case 301.

[0010] In some other embodiments, the side impact protection blocks 310 are further disposed on both sides of the seat main body 300. Furthermore, in these embodiments, the opening and the accommodating space are located at a position between the side impact protection blocks 310 and the upper edge of the case 301, although the present disclosure is not limited to this configuration.

[0011] The child car seat disclosed in this embodiment further includes a canopy 200 and a connecting structure 100 connecting the seat body 300 and the canopy 200. The canopy rods of the canopy 200 are removably connected to both the left and right sides of the seat body 300 via the connecting structure 100 of the present invention. The connecting structures 100 may be disposed separately or symmetrically on both the left and right sides of the seat body 300. Each of the connecting structures 100 is divided into two parts, one part being mainly a fixed seat 110 embedded in the storage space 305, and the other part being mainly a socket 130 connected to one canopy rod.

[0012] For ease of viewing, only two canopy rods of canopy 200 are shown, and the canopy rods shown do not have canopy fabric attached. Note that the canopy of this embodiment is shown with two canopy rods, first canopy rod 210 and second canopy rod 220, which can rotate relative to one another to collapse canopy 200 (as described in more detail below), but the inventive joint structure 100 is suitable for any number of canopy rods and for collapsible or non-collapsible canopy structures. While the inventive joint structure 100 includes a design that allows the two canopy rods to rotate relative to one another, such a design is not required and can be modified as appropriate based on the configuration of the canopy.

[0013] Next, components of a junction structure 100 according to one embodiment of the present invention will be described in brief with reference to FIGS. 4A to 5B.

[0014] As shown, each of the connecting structures 100 includes a fixing seat 110, a socket 130, a sealing portion 120, a first canopy rod fixing portion 140, a second canopy rod fixing portion 150, a cover 160, an elastic sealing portion 161, and an elastic canopy rod 162. The fixing seat 110 is a component embedded in the seat body 300, and the socket 130 is a component connected to the canopy 200. The socket 130 can be inserted into the fixing seat 110 to attach the canopy 200 to the seat body 300. The sealing portion 120 is located on the fixing seat 110 and is used to close the opening of the fixing seat 110 when the socket 130 is not inserted into the fixing seat 110. The first canopy rod fixing portion 140 and the second canopy rod fixing portion 150 are connected to the socket 130 to be connected to the first canopy rod 210 and the second canopy rod 220, respectively.

[0015] Next, the specific structure of the fixed seat 110 will be described with reference to FIGS. 4B, 9B, and 10B.

[0016] As shown in the figure, the fixed seat 110 has a cylindrical fixed seat side wall 112. The fixed seat side wall 112 has an open end 1121 and a receiving end 1122 arranged opposite each other. The fixed seat side wall 112 has a non-circular structure, for example, a substantially rectangular cross section, with a pair of opposing sides of the rectangle having arcuate edges. In this way, when a socket 130 having a shape corresponding to the fixed seat 110 is inserted into the fixed seat 110, the socket 130 can be prevented from rotating within the fixed seat 110. Note that the fixed seat side wall 112 may have other shapes, such as a square, trapezoid, or ellipse.

[0017] The fixed seat 110 also has a fixed seat edge 111, which extends outward from the edge of the open end 1121 of the fixed seat side wall 112. The fixed seat edge 111 facilitates fastening the fixed seat 110 to the seat main body 300 and can decorate the appearance of the fixed seat 110. In one embodiment, the fixed seat edge 111 is angled upward and extends from the open end 1121 of the fixed seat side wall 112 toward the storage end 1122, making it easier to fasten the fixed seat 110 to the seat main body 300 and enabling a better transitional combination of the fixed seat 110 and the seat main body 300.

[0018] The direction from the open end 1121 to the accommodation end 1122 of the fixed seat side wall 112 is called the insertion direction. In the insertion direction, the cross section of the fixed seat side wall 112 is approximately uniform. A stopper portion 114 is arranged on the inside of the fixed seat side wall 112. The stopper portion 114 is located between the open end 1121 and the accommodation end 1122 and protrudes inward from the inside of the fixed seat side wall 112. The stopper portion 114 may be close to the open end 1121. For example, the distance from the stopper portion 114 to the open end 1121 in the insertion direction is approximately 1 / 2 to 1 / 3 of the overall length of the fixed seat 110.

[0019] Next, the specific structure of the pore sealing portion 120 will be described with reference to FIGS. 6A and 6B.

[0020] As shown, the sealing portion 120 is located inside the fixed seat side wall 112 and is a component that is movable between the open end 1121 and the receiving end 1122. The sealing portion 120 has a sealing surface 121 at the open end 1121, and the sealing surface 121 has a shape that corresponds to the cross-sectional shape of the fixed seat side wall 112 at the open end 1121. In the illustrated embodiment, the sealing portion 120 is generally plate-shaped. However, it should be understood that the sealing portion 120 may have any suitable shape, such as a block shape or a cone shape, as long as it is suitable for closing the sealing surface 121 at the open end 1121.

[0021] In one embodiment, a barb portion 122 is disposed on the sealing portion 120. The barb portion 122 extends from the sealing surface 121 toward the accommodation end 1122 and has a hook protruding toward the fixed seat side wall 112. The barb portion 122 is configured to engage with the stopper portion 114 of the fixed seat side wall 112. When the sealing portion 120 is biased toward the open end 1121 by the elastic sealing portion 161, the barb portion 122 abuts against the stopper portion 114 from the accommodation end 1122 side, thereby preventing the sealing portion 120 from separating from the fixed seat 110. In one embodiment, the sealing portion 120 has a plurality of barbs 122, and a plurality of stopper portions 114 are disposed on the long and / or short sides of the fixed seat side wall 112. The plurality of barbs 122 are disposed to correspond to the stopper portions 114 on the long and / or short sides of the fixed seat side wall 112, respectively. In other embodiments, the stop positioning of the sealing portion 120 may be achieved in other ways, for example, the cross section of the open end 1121 may be set smaller than the sealing surface 121 so as to prevent the sealing portion 120 from separating from the fixed seat 110.

[0022] Next, the specific structures of the socket 130 and the first canopy rod fixing portion 140 will be described with reference to FIGS. 7A and 7B.

[0023] Although the socket 130 is disclosed as being assembled to the first canopy rod fastener 140, it should be understood that the socket 130 may be applied to different objects according to one or more embodiments of the present disclosure.

[0024] The socket 130 has a cylindrical socket side wall 131, and can be inserted into the fixed seat side wall 112 along the insertion direction through the open end 1121. A protrusion 132 is disposed on the outer side of the socket side wall 131 and protrudes outward from the outer side of the socket side wall 131. When the socket 130 is inserted into the fixed seat 110, the protrusion 132 can enter the fixed seat 110 beyond the stopper portion 114 and abut against the stopper portion 114 from the receiving end 1122 side, thereby preventing the socket 130 from separating from the fixed seat 110.

[0025] In one embodiment, the socket side wall 131 has a plurality of protrusions 132, which correspond to the stoppers 114 on the long and / or short sides of the fixing seat side wall 112, respectively. This design allows all sides of the socket 130 to be locked into the fixing seat 110, thereby increasing the stability of the canopy 200.

[0026] In one embodiment, the protrusion 132 extends on the socket side wall 131 along a direction perpendicular to the insertion direction, and slots 133 parallel to the insertion direction are respectively disposed on both ends of the protrusion 132 on the socket side wall 131. This design allows the protrusion 132 to collapse by elastic deformation, thereby facilitating it to overcome the stopper 114 during the insertion process of the socket 130. Furthermore, when a user needs to pull out the socket 130, the protrusion 132 can overcome the stopper 114 and separate from the fixing seat 110 with a slight force.

[0027] It should be understood that in other embodiments, the socket 130 may be secured to the retaining seat 110 in a different manner, such as a snap fit, a friction fit, or the like.

[0028] The first canopy fixing portion 140 is attached to the outer surface of the socket 130 along the insertion direction. In this way, when the socket 130 is fully inserted into the fixing seat 110, the first canopy fixing portion 140 is close to the side of the seat main body 300 and partially shields the joining structure 100, so that only a small portion of the entire joining structure 100 is exposed to the outside, thereby forming a neat and clean appearance. In this embodiment, the first canopy fixing portion 140 and the socket 130 are formed as one component, but it should be understood that in other embodiments, the first canopy fixing portion 140 and the socket 130 may be formed as separate components.

[0029] The first canopy fixing part 140 includes a first disk part 141 and a first canopy rod connecting part 142. The first disk part 141 is disposed on one side of the socket 130. The first canopy rod connecting part 142 has one end connected to the outer periphery of the first disk part 141 and the other end extending obliquely upward toward the child seat and connected to one end of the U-shaped structure of the first canopy rod 210. A hollow accommodating space 143 is disposed at the center of the first disk part 141 and is used to accommodate at least a portion of the second canopy rod fixing part 150, the elastic canopy rod 162, and the cover 160. A plurality of positioning grooves 144 are formed on the inner peripheral wall of the accommodating space 143 and are used for rotational positioning between the second canopy rod fixing part 150 and the first canopy rod fixing part 140.

[0030] The specific structure of the second canopy rod fixing portion 150 will be described with reference to FIGS. 8A and 8B.

[0031] The second canopy rod fixing portion 150 includes a second disk portion 151 and a second canopy connecting portion 152. The second disk portion is a portion rotatably attached to the first canopy fixing portion 140. The second canopy connecting portion 152 has one end connected to the outer periphery of the second disk portion 151 and the other end extending diagonally forward toward the child seat and connected to one end of the U-shaped structure of the second canopy rod 220. The rotating portion 153 is disposed on one side of the second disk portion 151 facing the first disk portion 141. The rotating portion 153 has a size that substantially corresponds to the size of the storage space 143 of the first disk portion 141, and is rotatably stored in the storage space 143. At least one positioning protrusion 154 is arranged on the outer periphery of the rotating part 153, and the positioning protrusion 154 corresponds to at least one positioning groove 144 on the inner circumferential wall of the accommodating space 143, so that the second canopy rod fixing part 150 is positioned at one or more specific angular positions relative to the first canopy rod fixing part 140. A through hole 155 is arranged at the center of the rotating part 153, and a part of the cover 160 passes through the second canopy rod fixing part 150 and connects to the first canopy rod fixing part 140, forming a rotational connection between the second canopy rod fixing part 150 and the first canopy rod fixing part 140.

[0032] A resilient canopy rod 162, such as a torsion spring, is disposed between the second disc portion 151 and the first disc portion 141. The resilient canopy rod 162 is used to bias the first canopy rod fixing portion 140 and the second canopy rod fixing portion 150 to rotate in the closing direction. For simplicity, the arrangement of the resilient canopy rod 162 will not be further described here.

[0033] Specific assembly of the child car seat according to the present invention will be described with reference to FIGS. 9A to 10B.

[0034] 9A and 9B, the socket 130 is inserted into the fixed seat 110. At this time, the protrusion 132 on the outer wall of the socket 130 engages with the stopper portion 114 on the inner wall of the fixed seat 110 from the side of the storage end 1122, holding the socket 130 inside the fixed seat 110. When pressed by the socket 130, the sealing portion 120 moves toward the storage end 1122 of the side wall of the fixed seat against the biasing force of the elastic sealing portion 161. The first canopy fixing portion 140 (and the first canopy rod 210 attached thereto) comes close to the side surface of the seat main body 300.

[0035] In the state shown in FIGS. 10A and 10B , the socket 130 is pulled out of the fixed seat 110, and the canopy rod is correspondingly removed. At this time, the sealing portion 120 is urged by the elastic sealing portion 161 to move to the open end 1121 of the fixed seat 110. The barbed portion 122 of the sealing portion 120 engages with the stopper portion 114 on the inner wall of the fixed seat 110 from the receiving end 1122 side, holding the sealing portion 120 inside the fixed seat 110. The size of the sealing portion 120 is designed so that the sealing surface 121 is flush with the open end 1121 when the barbed portion 122 engages with the stopper portion 114. In this way, the sealing surface 121 closes the open end 1121 of the fixed seat 110. In at least one embodiment, the sealing surface 121 is completely flush with the open end 1121.

[0036] 11A to 14C, another embodiment of a joining structure according to an embodiment of the present invention will be described. This embodiment is substantially the same as the previous embodiment, except that the joining structure further includes a release button 170. The function of the release button 170 is to facilitate separation of the joining structure 100 from the fixing seat 110.

[0037] As shown, the release button 170 is disposed on the side of the socket 130 and is partially inserted into the socket 130. More specifically, the release button 170 can slide substantially vertically (i.e., perpendicular to the insertion direction of the socket 130) between a locked position away from the socket 130 and an unlocked position adjacent to the socket 130.

[0038] A pressing portion 171 and a locking portion 172 are provided on one side of the release button 170 away from the socket 130. The pressing portion 171 and the locking portion 172 are exposed to the outside of the socket 130 and both protrude outward perpendicular to the insertion direction of the socket 130. The locking portion 172 is closer to the fixed seat 110 than the pressing portion 171. A resilient release button fixing portion 173 is provided on one side of the release button 170 facing the socket 130. One end of the spring-shaped resilient release button 163 is fixed to the resilient release button fixing portion 173 and the other end abuts against the inside of the socket 130 to urge the release button 170 toward the locked position. The socket 130 is provided with a position restricting portion 134 that prevents the release button 170 from moving away from the socket 130.

[0039] In this way, when socket 130 is inserted into fixed seat 110, pressing portion 171 remains on the outside of fixed seat 110, and locking portion 172 is inserted into fixed seat 110 and engages with the inside edge of fixed seat 110. Therefore, release button 170 can hold socket 130 in fixed seat 110. When the user needs to release fixed seat 110, the user can press pressing portion 171 toward socket 130 and easily separate socket 130 from fixed seat 110.

[0040] In embodiments where release button 170 is provided, protrusion 132 and slot 133 may not be located on socket 130 .

[0041] In short, one or more embodiments of the present invention provide a joining structure 100 that can easily join the seat body 300 and the canopy 200 of a child car seat and that leaves no obvious holes even when the canopy 200 is removed. The joining structure 100 of the present invention can provide a generally clean appearance to the child car seat, regardless of whether the canopy 200 is attached or not. Furthermore, the joining structure 100 of the present invention is not limited to use with child car seats, but can also be used to join any two objects.

[0042] 15-20, another embodiment of the present invention will be described. As shown, a joining structure 910 according to another embodiment of the present invention can be used in a variety of applications, including, but not limited to, child carriers, child dining chairs, wheelchairs, and recliners. Additionally, the joining structure 910 can be attached to a variety of other equipment in addition to the canopy mechanism 50. For simplicity, the following description will illustrate an example in which the joining structure is used in a child car seat and attached to the canopy mechanism 50.

[0043] As shown in Fig. 15, Fig. 15 is a schematic diagram of a child car seat according to another embodiment of the present invention, which includes a seat portion 20 and a backrest portion 30. The seat portion 20 and the backrest portion 30 are spaced apart from each other, for example, by approximately 90 degrees, and surround a space in which a user sits. Of course, the seat portion 20 and the backrest portion 30 may be spaced apart at other angles. To improve seating comfort, a pillow portion 40 is further disposed at the upper end of the backrest portion 30, on which the user's head can rest.

[0044] Also, there is a growing trend to additionally install a canopy mechanism 50 on a child car seat to provide protection from sunlight, rain, and wind, or for privacy and safety. Referring to FIG. 16, FIG. 16 is a schematic diagram of a child car seat according to one embodiment of the present invention, showing that the child car seat is inserted into and connected to it by a connecting structure 910. Specifically, a fixed seat 32 is provided on the back of the seat back 30. The fixed seat 32 may be in the form of, for example, a blind hole, i.e., has an opening and a bottom opposite the opening. In one embodiment, two fixed seats 32 are provided symmetrically with respect to the central longitudinal axis of the seat back 30. Two connecting structures 910 are inserted into the two fixed seats 32, respectively, and the two connecting structures 910 are commonly attached to the canopy mechanism 50. For ease of explanation, the canopy mechanism 50 is shown only by its main frame structure without its canopy shield.

[0045] The joining structure 910 includes two main parts: a socket 912 and a sealing portion 914. The sealing portion 914 is disposed in a fixed seat 32 provided in the backrest 30, and the socket 912 is insertable into and removable from the fixed seat 32. Specifically, the sealing portion 914 is always disposed in the fixed seat 32, and the socket 912 abuts against the sealing portion 914 when inserted into the fixed seat 32. When the socket 912 is removed from the fixed seat 32, the sealing portion 914 moves to close the opening of the fixed seat 32. Figure 17 schematically shows the socket 912 of the joining structure 910 and the attached canopy mechanism 50. Referring to Figure 18, Figure 18 is a schematic diagram of a socket of a joining structure according to the present invention.

[0046] The socket 912 includes an abutting end 921, a connecting end 922, and an intermediate portion 923 disposed between the abutting end 921 and the connecting end 922. The abutting end 921 abuts against the sealing portion 914 when the socket 912 is inserted into the fixed seat 32, and the connecting end 922 may be attached to, for example, a component of the canopy mechanism 50. The intermediate portion 923 is provided with a locking portion 9231, an unlocking portion 9232, and a resetting portion 9233. The locking portion has, for example, a hook shape and extends in a direction substantially perpendicular to the insertion direction of the socket 912. The unlocking portion 9232 and the locking portion 9231 may be formed, for example, as an integral structure. When the unlocking portion 9232 is moved in a direction substantially perpendicular to the insertion direction of the socket 912, the locking portion 9231 also moves in this direction. In this embodiment, the reset portion 9233 has the form of an elastic sheet, and the unlocking portion 9232 must move in a direction approximately perpendicular to the insertion direction of the socket 912 against the elastic force of the reset portion 9233. Therefore, after the unlocking portion 9232 is released, the reset portion 9233 in the form of an elastic sheet releases its elastic force and presses the locking portion 9231 to reset it again, i.e., move it to its initial position. The unlocking portion 9232 is configured to be exposed to the outside of the fixed seat 32, which makes it easy to operate the unlocking portion 9232 from outside the fixed seat 32. At the same time, a concave-convex structure is arranged on the pressing surface of the unlocking portion 9232 to increase friction and prevent slippage.

[0047] 19 shows a specific structure of the sealing portion 914. In a preferred embodiment, as shown in FIG. 19, the overall structure of the sealing portion 914 is elliptical to fit the elliptical fixing seat 32. Of course, other structural shapes can be applied to the sealing portion 914 as long as the outer contour of the sealing portion 914 matches the contour of the fixing seat 32. Of course, the outer contour of the sealing portion can be smaller than the contour of the fixing seat 32 to facilitate manufacturing and reduce costs.

[0048] The sealing portion 914 has the form of a hood body, i.e., the sealing portion 914 includes a cover body 941 and a side wall 942 extending perpendicularly from the periphery of the cover body 941. An engagement portion 943 is disposed on the side wall 942. An elastic member 916 is further disposed to provide a restoring force against the movement of the sealing portion 914 so that the sealing portion 914 can move smoothly to close the opening of the fixed seat 32. For this purpose, the elastic member 916 is disposed on the hood body of the sealing portion 914, i.e., the elastic member 916 is housed between the cover body 941 and the bottom of the fixed seat 32 facing the opening. When the abutment end 921 of the socket 912 inserted into the fixed seat 32 abuts against the cover body 941 of the sealing portion 914, the elastic member 916 is compressed between the cover body 941 of the sealing portion and the bottom of the fixed seat 32. When the socket 912 is removed from the fixed seat 32 , the compressed elastic member 916 provides a restoring force that pushes the sealing portion 914 to move so as to close the opening of the fixed seat 32 .

[0049] 20, which is a schematic diagram of a joint structure 910 according to the present invention, illustrating the mating relationship between the socket 912 and the sealing portion 914, and describes in detail the operation process of the joint structure 910 according to one embodiment of the present invention.

[0050] The hole sealing portion 914 is always disposed on the fixed seat 32, and the elastic member 916 abuts between the bottom of the fixed seat 32 and the hole sealing portion 914. In the illustrated embodiment, the elastic member 916 abuts between the bottom of the fixed seat 32 and the cover body 941 of the hole sealing portion 914. Figure 20 shows a state in which the socket 912 is inserted into the fixed seat 32. At this time, the abutting end 921 of the socket 912 abuts against the cover body 941, and the locking portion 9231 of the socket 912 is locked by a locking structure provided corresponding to the fixed seat 32. The canopy mechanism 50, to which the connecting end 922 of the socket 912 is attached, is connected to the child car seat in this state.

[0051] When the canopy mechanism 50 will not be used for a long period of time or needs to be cleaned, the unlocking portion 9232 may be pressed from the outside of the fixed seat 32 in a direction generally perpendicular to the insertion direction of the socket 912, causing the unlocking portion 9232 to move along a direction generally perpendicular to the insertion direction. Because the unlocking portion 9232 and the locking portion 9231 are formed as an integral structure, the movement of the unlocking portion 9232 also causes the locking portion 9231 to move along a direction generally perpendicular to the insertion direction, causing the locking portion 9231 to be separated from the locking structure arranged corresponding to the fixed seat 32, and the socket 912 and the canopy mechanism 50 attached thereto can be removed at this point.

[0052] When the canopy mechanism 50 needs to be reinstalled, the socket 912 is inserted into the fixed seat again while the unlocking portion 9232 is pressed. In the process of pressing the unlocking portion 9232, the resetting portion 9233 is compressed. Therefore, when the locking portion 9232 is released after the socket 912 is inserted into a predetermined position, the locking portion 9231 again cooperates with the corresponding locking structure in the fixed seat 32 under the action of the restoring force of the resetting portion 9233 to lock the socket 912. In this way, the canopy mechanism 50 connected to the connecting end 922 of the socket 912 is reconnected to the child seat.

[0053] In the joining structure 910 according to one embodiment of the present invention, the sealing portion 914 is always disposed on the fixed seat 32. Therefore, when it is necessary to remove the canopy mechanism 50, even if the socket 912 is removed from the fixed seat 32, the sealing portion 914 can still move due to the action of the elastic force of the elastic member 916 to close the opening of the fixed seat 32. This improves the overall aesthetic appearance after the socket 912 is removed and prevents the user's fingers or other parts from being accidentally injured by the fixed seat, thereby improving safety.
