[0072] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0073] Child seats often include a base structure, which is suitable for being detachably connected to a buckle structure of a vehicle to achieve the installation of the child seat. In addition, the base structure is provided with a sliding structure that can slide relative to the seat body, and at the same time, the sliding structure is also connected to the buckle structure, so that the above-mentioned arrangement requires the sliding structure to be frequently stressed and has a high intensity of use. If the size of the sliding structure is directly increased, it is easy to be restricted by its installation form, and the weight will increase significantly; if the strength and rigidity of the sliding structure are insufficient, it is easy to affect the normal use of the child seat and even pose a safety hazard.

[0074] In view of this, see Figure 1-Figure 17 In an embodiment of the present application, a base 100 is provided for a child seat 10, and the child seat 10 is adapted to be detachably connected to a buckle structure. For example, see Figure 1-Figure 3 In some embodiments, the child seat 10 may further include a seat body 200, which is disposed above the base 100 and is slidably connected to the base 100 (the seat body 200 may also be rotatably connected to the base 100), so that the position and orientation of the seat body 200 can be adjusted through the relative movement of the seat body 200 and the base 100. The base 100 includes a bracket assembly 110, a fixing assembly 120, and a locking assembly 140.

[0075] For details, see Figure 2-Figure 4 The support assembly 110 includes a support plate 111. As required, the support plate 111 can be in any suitable structural shape, and the support plate 111 can have a connection structure suitable for fixed connection with the seat body 200. In addition, the fixing assembly 120 includes a connecting portion 122 and a sliding portion 121 connected to each other, the sliding portion 121 is movably connected to the support plate 111, and can slide relative to the support plate 111 along the first direction X, and the connecting portion 122 is suitable for detachably connecting to the buckle structure. It can be understood that the sliding portion 121 slides relative to the support plate 111, that is, it can be used to reciprocate the position of the seat body 200 along the first direction X, so as required, the above-mentioned first direction X can be any suitable direction.

[0076] Based on the above sliding arrangement, in order to lock or unlock the sliding of the sliding portion 121 relative to the bracket plate 111 in different states, see Figure 2 , Figure 7 , Fig. 9 as well as Figure 11-Figure 12The locking assembly 140 is movably connected to the bracket assembly 110. The locking assembly 140 can move to a locking position and an unlocking position relative to the bracket assembly 110. When the locking assembly 140 is in the locking position, the sliding portion 121 is fixed to the bracket plate 111. When the locking assembly 140 is in the unlocking position, the sliding portion 121 and the bracket plate 111 are unlocked. The locking assembly 140 may specifically include a handle 141, a pin 142, a transmission assembly 143, and a return spring 144. The return spring 144 is connected to the housing of the bracket assembly 110 or the base 100. One end of the handle 141 is located inside the housing of the base 100, and the other end is located outside the housing of the base 100. The part of the handle 141 extending into the housing of the base 100 is connected to the transmission assembly 143, and the transmission assembly 143 is also connected to the pin 142. After the handle 141 obtains the driving force, it drives the transmission assembly 143 to move, thereby driving the pin 142 to move relative to the bracket assembly 110. When the pin 142 of the locking assembly 140 moves to the locking position, the sliding part 121 is fixed to the bracket plate 111. When the pin 142 of the locking assembly 140 moves to the unlocking position, the locking of the sliding part 121 and the bracket plate 111 is released. When the handle 141 is in the first position, the pin 142 is in the locking position. When the handle 141 is pulled toward the outside of the housing of the base 100 to the second position by force, the pin 142 is driven to the unlocking position, and the return spring 144 connected to the transmission assembly 143 is stretched. When the handle 141 is not driven, the return spring 144 drives the transmission assembly 143 to move, thereby driving the handle 141 to return to the first position and driving the pin 142 to return to the locking position.

[0077] See also Figure 2-Figure 4 , the bracket plate 111 is provided with a first slide groove 1111 which is connected with the sliding part 121, and the first slide groove 1111 extends along the first direction X. It is understandable that the sliding part 121 can extend into the first slide groove 1111 and cooperate with the first slide groove 1111 to form a sliding connection, so that the sliding part 121 can slide relative to the bracket plate 111 along the first direction X. Therefore, in particular, the bracket plate 111 is also provided with a first convex rib 1116, and the first convex rib 1116 extends along the first direction X, so that the first convex rib 1116 can reduce the risk of deformation of the bracket plate 111 along the first direction X. In addition, the first convex rib 1116 is located on one side of the first slide groove 1111 along the second direction, and the second direction intersects with the first direction X. It is understandable that the relative arrangement of the first convex rib 1116 and the first slide groove 1111 along the second direction can make the area of ​​the bracket plate 111 part that can be strengthened by the first convex rib 1116 larger, thereby achieving a better strengthening effect.

[0078] It can be seen that the base 100 of the present application movably connects the sliding part 121 to the bracket plate 111, and the bracket plate 111 is provided with a first slide groove 1111 that is connected to the sliding part 121 and extends along the first direction X, and the sliding part 121 can slide relative to the bracket plate 111 along the first direction X, so that the relative sliding movement between the bracket plate 111 and the sliding part 121 can be used to adjust the position of the seat body 200. In particular, the bracket plate 111 is also provided with a first convex rib 1116, the first convex rib 1116 extends along the first direction X, and the first convex rib 1116 is located on one side of the first slide groove 1111 along the second direction, and the second direction intersects with the first direction X. Compared with the adjustment structure that also adopts a sliding connection in the related art, the present application can reduce the structural strength and rigidity problems caused by the open hole structure of the first slide groove 1111 without increasing the size of the bracket plate 111 as much as possible. Therefore, the base 100 of the present application can make the bracket plate 111 have higher strength and rigidity.

[0079] In order to further increase the strength and rigidity of the bracket plate 111, see Figure 2-Figure 4 In some embodiments, the support plate 111 is further provided with a second rib 1117, and the second rib 1117 is provided on one side of the first chute 1111 along the first direction X. In different embodiments, the second rib 1117 may be entirely located on one side of the first chute 1111 along the first direction X, or may be partially located on one side of the first chute 1111 along the first direction X. In addition, the second rib 1117 extends along the second direction, and this arrangement can reduce the risk of deformation of the support plate 111 along the second direction. In addition, the second rib 1117 can be connected to one end of the first rib 1116 along the first direction X. On the one hand, this arrangement can enable the first rib 1116 and the second rib 1117 to form an interaction force, thereby making the first rib 1116 and the second rib 1117 less likely to deform themselves, and having a better strengthening effect. On the other hand, this arrangement can also reduce the manufacturing cost, that is, the first rib 1116 and the second rib 1117 can be manufactured in one piece (and the plate body of the support plate 111 can also be manufactured in one piece at the same time). In other embodiments, the second convex rib 1117 may be spaced apart from the first convex rib 1116 .

[0080] On the other hand, in order to prevent the weight of the bracket plate 111 from being too large while adding the first rib 1116, see Figure 2-Figure 4In some embodiments, the support plate 111 is provided with a plurality of first hollow holes 1119, each of which is provided on the side of the first rib 1116 away from the first slide groove 1111, and each of the first hollow holes 1119 is arranged at intervals along the first direction X. It can be understood that the above-mentioned first hollow holes 1119 can play a role in reducing the overall weight of the support plate 111, and because the first rib 1116 is located between each first hollow hole 1119 and the first slide groove 1111, that is, each first hollow hole 1119 is farther away from the first slide groove 1111, thereby reducing the influence of each first hollow hole 1119 on the strength and rigidity of the support plate 111 portion around the first slide groove 1111. According to requirements, the first hollow hole 1119 can have any suitable cross-sectional shape, such as any one of a circle, a runway shape (a waist-shaped hole), an ellipse, and a rectangle.

[0081] On the other hand, see Figure 2-Figure 4 In some embodiments, the first slide groove 1111 is provided at the front end of the bracket plate 111, and the rear end of the bracket plate 111 is further provided with a first limiting groove 1113 that is slidably matched with the sliding portion 121, and the first limiting groove 1113 extends along the first direction X. According to the above configuration, in some embodiments, the sliding portion 121 may include two parts, which are slidably matched with the first limiting groove 1113 and the first slide groove 1111, respectively. Along the direction from the first slide groove 1111 to the first limiting groove 1113, the vertical groove width of the first limiting groove 1113 gradually increases. It can be understood that the sliding portion 121 can not only slide in the first limiting groove 1113 along the first direction X, but also slide in the vertical direction. This arrangement can provide the sliding portion 121 with a larger swing displacement margin, thereby avoiding to a certain extent the damage to the base 100 and the connected structure caused by the hard contact caused by the swing, and the first limiting groove 1113 with a gradually varying width also has a clamping effect, thereby avoiding excessive vertical displacement of the sliding portion 121.

[0082] On the other hand, in some embodiments, the thickness of the support plate 111 is between 1.6 mm and 2.4 mm. For example, in some embodiments, the thickness of the support plate 111 can be any one of 1.6 mm, 1.8 mm, 2 mm, 2.2 mm, and 2.4 mm. With the above configuration, the strength and rigidity problems caused by the too small thickness of the support plate 111 can be avoided, and the weight problem caused by the too large thickness of the support plate 111 can also be avoided.

[0083] See also Figure 2-Figure 4In some embodiments, the support plate 111 includes a bottom plate 112 extending transversely and a vertical plate 113 extending upward at the rear end of the bottom plate 112, the first slide groove 1111 and the first rib 1116 (may also include a second rib 1117) are both provided on the bottom plate 112, and the upper end of the vertical plate 113 is provided with a second slide groove 1112 suitable for cooperating with the seat body 200 of the child seat 10. It can be understood that the second slide groove 1112 can be used to further adjust the position of the seat body 200 relative to the support plate 111, so that the extension direction of the second slide groove 1112 can intersect with the first direction X. A reinforcing protrusion 1118 is provided below the second slide groove 1112. In addition, the positions of the above-mentioned components are arranged so that the sliding force at the first slide groove 1111 mainly affects the bottom plate 112, and the sliding force at the second slide groove 1112 mainly affects the vertical plate 113, so that the first rib 1116 and the reinforcing rib are arranged on the bottom plate 112 and the vertical plate 113 respectively, so that the effect of the reinforcing structure can be more concentrated, and the reinforcing structure is targeted at the main force-bearing parts, so that the reinforcing effect is better. In addition, in some embodiments, the reinforcing protrusion 1118 forms a protrusion on one side wall of the vertical plate 113 and a groove on the other side wall of the vertical plate 113, and the protrusion height and the recessed depth of the reinforcing protrusion 1118 are both between 0.4mm and 0.6mm. Exemplarily, in some embodiments, the protrusion height and / or the recessed depth of the reinforcing protrusion 1118 can be 0.4mm, 0.5mm, 0.6mm.

[0084] Based on the definition of the first limiting groove 1113 in the above embodiment, see Figure 7-Figure 11In some embodiments, the bracket assembly 110 also includes a limit block 114, which is rotatably connected to the bracket plate 111. The limit block 114 is provided with a second limit groove 1141 that slidably cooperates with the sliding portion 121. The second limit groove 1141 is located on one side of the first limit groove 1113 along the thickness direction of the limit block 114. The second limit groove 1141 extends along the first direction X. An elastic member 115 is also provided between the limit block 114 and the bracket plate 111. The elastic member 115 is used to drive the limit block 114 to rotate relative to the bracket plate 111 so that the limit block 114 presses down the sliding portion 121. The elastic member 115 can specifically be a torsion spring. It can be understood that the limit block 114 is arranged on one side of the thickness direction of the bracket plate 111, and can rotate relative to the bracket plate 111 along an axis parallel to the thickness direction of the bracket plate 111. At the same time, since the sliding portion 121 is located on the other side of the limit block 114 away from the rotation axis, and the sliding portion 121 is simultaneously penetrated by the second limit groove 1141 of the limit block 114 and the first limit groove 1113 of the bracket plate 111, and then based on the gradual increase of the vertical groove width of the first limit groove 1113 (the larger part is away from the rotation axis of the limit block 114), when the limit block 114 rotates, under the action of the elastic member 115, the top wall of the second limit groove 1141 can press the sliding portion 121, so that the sliding portion 121 can vertically abut or approach the bottom wall of the first limit groove 1113 under normal conditions, so that the child seat 10 can limit the tilt angle of the child seat 10 while having an angle swing margin, and can perform angle reset. Furthermore, in order to allow the limit block 114 to have a larger swing margin and avoid excessive hard contact, in some embodiments, the bracket plate 111 is provided with a first pivot hole 1114 and a second pivot hole 1115, and the front end of the limit block 114 is rotatably engaged with the first pivot hole 1114, that is, this engagement can make the limit block 114 rotate relative to the bracket plate 111, and at the same time, the rear end of the limit block 114 can also slidably engage with the second pivot hole 1115.

[0085] For the specific structure of the sliding portion 121, see Figure 2-Figure 5In some embodiments, the sliding portion 121 includes a reinforcing plate 1211 and a cover 1212. The reinforcing plate 1211 is slidably connected to the bracket plate 111, and the cover 1212 is covered on the side of the reinforcing plate 1211 away from the bracket plate 111. The reinforcing plate 1211 is provided with a matching portion 12111, and the matching portion 12111 forms a protrusion on the side of the reinforcing plate 1211 close to the cover 1212 and abuts against the cover 1212. This setting can ensure that the two form a stable connection during the connection process through the matching portion 12111 abutting against the cover 1212, thereby enhancing the connection strength and making it easier to connect and position. According to requirements, the matching portion 12111 can be in any suitable structural shape, such as any one of a circle, an ellipse, a triangle, and a rectangle. In addition, the matching portion 12111 can be recessed on the side of the reinforcing plate 1211 away from the cover body 1212, that is, the matching portion 12111 can be formed by stamping the main structure of the reinforcing plate 1211. This arrangement can avoid increasing the weight of the reinforcing plate 1211 and has a low manufacturing cost. In different embodiments, the reinforcing plate 1211 and the cover body 1212 can be detachably connected, for example, the two can be connected by bolts; in other embodiments, the reinforcing plate 1211 and the cover body 1212 can be manufactured separately first, and then connected in one piece, which can also make the matching portion 12111 play the effect of strengthening the connection strength.

[0086] For further information, see Figure 2-Figure 5 In some embodiments, the reinforcing plate 1211 includes a first end and a second end opposite to each other, the matching portion 12111 is located at the first end, and the connecting portion 122 is connected to the second end (it can be directly connected or indirectly connected). This arrangement makes the installation and positioning of the reinforcing plate 1211 more accurate and convenient, and both ends have a high connection strength. In addition, see Figure 5In some embodiments, the reinforcing plate 1211 is provided with a plurality of second hollow holes 12112 spaced apart from each other, and each second hollow hole 12112 is distributed along the first direction X. The second hollow holes 12112 can be used to penetrate the locking assembly 140, and the state in which the locking assembly 140 extends into each second hollow hole 12112 can correspond to different locking positions of the locking assembly 140. Based on this, the matching portion 12111 can be provided on one side of each second hollow hole 12112 along the first direction X. This arrangement can make the strength and rigidity of the reinforcing plate 1211 itself and its connection position better. In addition, in some embodiments, the aperture of each second hollow hole 12112 can be between 8.24 mm and 12.36 mm. Exemplarily, the aperture of each second hollow hole 12112 can be 8.24 mm, 9 mm, 10 mm, 11 mm, 12 mm or 12.36 mm, etc. This arrangement can prevent the aperture of each second hollow hole 12112 from being too small, which affects the design size of the corresponding locking assembly 140 and the movement margin of each position switch, and also avoids the strength and rigidity problems caused by the aperture of each second hollow hole 12112 being too large. In addition, the reinforcing plate 1211 can also be provided with a reinforcing part at the second end. In order to play a reinforcing role without excessively increasing the weight, the thickness of the reinforcing part can be less than the average thickness of the reinforcing plate 1211, and one or more openings can be provided.

[0087] The embodiment of the second aspect of the present application further provides a child seat 10, comprising a base 100, a seat body 200 and a headrest assembly 300 of any of the above embodiments. The seat body 200 is movably connected to the base 100, and the headrest assembly 300 is movably connected to the seat body 200. The above arrangement enables the seat body 200 to move and / or rotate and / or swing relative to the base 100, and the headrest assembly 300 can further move, and its specific movement mode can be reciprocating movement along a direction parallel to the backrest plane of the seat body 200.

[0088] In order to further strengthen the structure of each part of the child seat 10, on the one hand, see Figure 14-16In some embodiments, the headrest assembly 300 includes a buffer body 310, a headrest board 320 connected to the back of the buffer body 310, and a passer 330 connected between the buffer body 310 and the headrest board 320. Among them, as for the function of the passer 330, when a child uses the child seat 10, the safety belt of the child seat 10 can be passed through the passer 330 to provide protection for the child sitting there. In addition, when a child uses the child seat 10, the position of the headrest assembly 300 can be more conveniently adjusted through the passer 330, so that the safety belt can be located in a suitable position according to the size and body shape of the user, and the use of the safety belt can be made more comfortable by cooperating with different adjustment parts. For other structures and settings of the passer 330, reference can be made to the relevant technology, which will not be repeated here. Based on this, a first reinforcing rib 321 can be provided between the passer 330 and the headrest board 320. Due to the installation structure of the passer 330 , the provision of the first reinforcing rib 321 can prevent the passer 330 from being loosened during installation and enhance the structural strength around the passer 330 .

[0089] On the other hand, see Figure 14-16 In some embodiments, the headrest assembly 300 may further include a rod assembly slidably connected to the headrest plate 320, and the rod assembly may be specifically used for adjusting or installing the headrest assembly 300. Based on this, a second reinforcing rib 322 may be provided between the rod assembly and the headrest plate 320. When the second reinforcing rib 322 is connected to the rod assembly and / or the headrest plate 320, the arrangement may enhance the structural strength of the rod assembly and / or the headrest plate 320 connected thereto. In addition, when the rod assembly slides relative to the headrest plate 320, the second reinforcing rib 322 may abut against the rod assembly and / or the headrest plate 320, thereby generating an extrusion force to prevent the rod assembly from shaking, thereby enhancing the reliability and service life of the sliding connection of the rod assembly.

[0090] On the other hand, see Figure 14-17In some embodiments, the upper end of the headrest board 320 is connected to the buffer body 310, and the lower end is rotatably connected to the seat body 200. The lateral side of the headrest board 320 is provided with a limiting protrusion 324 to ensure the stability of the headrest board 320 when sliding up and down relative to the seat body 200. Specifically, the seat body 200 includes a backrest portion and a wing portion, the backrest portion includes a backrest board 210, and the backrest board 210 is provided with a guide rail. The limiting protrusion 324 cooperates with the guide rail on the backrest board 210, so that the headrest board 320 is slidably connected to the backrest board 210 and can slide up and down relative to the backrest board 210, so that the vertical height of the buffer body 310 of the headrest assembly 300 relative to the seat body 200 can be adjusted. Corresponding to the actual use scenario, there can be two (or two groups) of limiting protrusions 324, and they can be symmetrically located on the left and right sides when the user sits on the seat body 200. The side of the headrest plate 320 close to the limiting protrusion 324 is provided with a third reinforcing rib 323, and in the vertical direction, the third reinforcing rib 323 is at least partially provided below the limiting protrusion 324. A rotation axis for the headrest plate 320 to rotate relative to the seat body 200 may be provided below the limiting protrusion 324, and the above arrangement is to make the third reinforcing rib 323 at least partially provided on the side of the limiting protrusion 324 close to the rotation axis. According to the force analysis, after the limiting protrusion 324 is subjected to the abutting force, it will have a greater impact on the side of the headrest plate 320 close to the rotation axis. Therefore, the third reinforcing rib 323 can enhance the overall structural strength of the headrest plate 320, and enhance the reliability and service life of the rotation connection of the headrest plate 320.

[0091] In addition, see Figure 14-16 In some embodiments, the headrest plate 320 includes a first hinge end 325 located at the bottom, and the position of the hinge end corresponds to the rotation axis of the headrest plate 320 relative to the seat body 200 described in the above embodiment. The first hinge end 325 is provided with a first latch hole 326 arranged transversely, and the first latch hole 326 is a blind hole. The child seat 10 also includes a latch, one end of which is inserted into the blind hole and the other end is inserted into the seat body 200. The above-mentioned first latch hole 326 and latch can have two groups, and can be symmetrically located on the left and right sides when the user sits on the seat assembly. It can be understood that the first latch hole 326 is a blind hole, and the arrangement of the latch corresponding to the first latch hole 326 can effectively reduce the depth of the first latch hole 326 and the length of the latch, that is, it can avoid the strength and rigidity problems caused by the excessive length of the latch, and can save manufacturing costs.

[0092] In addition, see Figure 14-16In some embodiments, the first hinged end 325 is further provided with an observation through hole 327, which is provided at the outer peripheral side of the first latch hole 326 and communicates with the first latch hole 326. The child seat 10 further includes a latch, one end of which is inserted into the first latch hole 326 and the other end is inserted into the seat body 200, and the latch is exposed in the observation through hole 327. The above arrangement allows the position of the latch in the first latch hole 326 to be observed through the observation through hole 327. In addition, in some embodiments, the first latch hole 326 can be combined with the above embodiment and set as a blind hole, thereby avoiding the problem of confirming the latch position caused by the setting of the blind hole, and thus it is difficult to ensure a reliable connection; in other embodiments, the first latch hole 326 can also be set as a through hole.

[0093] Regarding the movement forms of the various components of the child seat 10, on the one hand, in some embodiments, the headrest assembly 300 includes a buffer body 310 and a headrest board 320 connected to the back of the buffer body 310, and the buffer body 310 can be specifically bonded to the headrest board 320. The seat body 200 includes a backrest board 210, and the headrest board 320 is slidably connected to the backrest board 210 and can slide up and down relative to the backrest board 210; on the other hand, in some embodiments, the seat body 200 is configured to be able to rotate around a vertical axis, slide horizontally, or rotate around a horizontal axis relative to the base 100. For the corresponding movement structure to achieve the above-mentioned movement forms, reference can be made to the relevant descriptions and related technologies of the aforementioned embodiments, which will not be repeated here. In addition to the above-mentioned movement forms, the child seat 10 can also have other forms of movement according to needs.

[0094] In addition, see Figure 6 , Figure 8 as well as Fig.13 In some embodiments, the child seat 10 further includes a side impact protection block 400, which is connected to the lateral side of the seat body 200. This arrangement can prevent the user and the child seat 10 from being injured when the lateral movement of the child seat 10 is too large.

[0095] For other structures of the child seat 10, reference may be made to the relevant art, which will not be described in detail here. Thanks to the improvements of the base 100 in the above embodiments, the child seat 10 in the second embodiment of the present application has the same technical effects as the base 100 in the above embodiments. This will not be described in detail here.

[0096] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0097] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or", "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.
