Description

Technical Field

[0001] This utility model relates to the field of child safety products technology, specifically to a child safety seat. Background Technology

[0002] Child car seats are designed specifically for children of different ages, installed in cars, and effectively improve children's safety while traveling. In the event of a collision or sudden deceleration, they reduce the impact force on children and restrict their body movement, thus minimizing injury and ensuring their safety while traveling.

[0003] To provide children with a more comfortable riding environment, child safety seats are generally equipped with angle adjustment devices. However, in actual use, when a child safety seat is hit, the locking part of the angle adjustment device is prone to detach from the base and accidentally come out of the fixed position (i.e., it jumps out of the gear). In other words, the existing seat angle adjustment device is prone to jumping out of the gear when hit. Utility Model Content

[0004] The purpose of this invention is to at least solve the problem of existing child safety seats frequently shifting gears. This purpose is achieved through the following technical solution:

[0005] The first aspect of this utility model discloses a child safety seat, comprising:

[0006] Base;

[0007] A seat, which is movably mounted on a base along a first direction, and a body cover is provided at the bottom of the seat;

[0008] An adjusting member is movably connected to the bottom cover of the main body along the first direction. A locking member is provided at the first end of the adjusting member. When the adjusting member moves relative to the bottom cover of the main body along the first direction, it drives the locking member to switch between a locked state and an unlocked state. In the locked state, the seat is fixed relative to the base. In the unlocked state, the seat is movable relative to the base.

[0009] The second end of the adjusting member is provided with a limiting part, and the limiting part forms a limiting space on the side opposite to the first end along the first direction;

[0010] A fitting component is disposed on the seat, and the fitting component is adapted to the limiting portion and accommodated within the limiting space.

[0011] The child safety seat of this invention includes a base, a seat, an adjusting member, and a mating member. The adjusting member, which corresponds to the seat's base cover, controls the locking member located at its first end to operate when moving in a first direction, thereby adjusting the seat's position relative to the base. By providing a limiting part at the second end of the adjusting member and forming a limiting space on the side of the limiting mechanism opposite to the first end, and simultaneously providing a mating member on the seat that is adapted to and accommodated within the limiting space, the limiting part and the mating member work together to limit the adjusting member in at least two different directions. This effectively prevents the adjusting member from moving relative to the base cover due to external force when the child safety seat is impacted, thus helping to solve the problem of existing child safety seats easily skipping gears.

[0072] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0073] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also mean including the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0074] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0075] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0076] Child car seats are designed specifically for children of different ages, installed in cars, and effectively improve children's safety while traveling. In the event of a collision or sudden deceleration, they reduce the impact force on children and restrict their body movement, thus minimizing injury and ensuring their safety while traveling.

[0077] To provide children with a more comfortable riding environment, child safety seats are generally equipped with angle adjustment devices. However, in actual use, when a child safety seat is hit, the locking part of the angle adjustment device is prone to detach from the base and accidentally come out of the fixed position (i.e., it jumps out of the gear). In other words, the existing seat angle adjustment device is prone to jumping out of the gear when hit.

[0078] To solve the above problems, such as Figures 1-18As shown, this utility model proposes a child safety seat 100. In terms of overall design, the child safety seat 100 includes a base 20, a seat 10, an adjustment component 30, and a mating component 50. The seat 10 is movably mounted on the base 20 along a first direction. A main body cover 112 is provided at the bottom of the seat 10. The adjustment component 30 is movably connected to the main body cover 112 along the first direction. A locking component 40 is provided at the first end of the adjustment component 30. When the adjustment component 30 moves relative to the main body cover 112 along the first direction, it drives the locking component 40 to switch between a locked state and an unlocked state. In the locked state, the seat 10 is fixed relative to the base 20. In the unlocked state, the seat 10 is movable relative to the base 20.

[0079] Furthermore, the second end of the adjusting member 30 is provided with a limiting part 31, and the limiting part 31 forms a limiting space 3101 on the side opposite to the first end along the first direction a. The mating member 50 is provided on the seat 10, and the mating member 50 is adapted to the limiting part 31 and accommodated within the limiting space 3101.

[0080] Specifically, by providing a limiting part 31 at the second end of the adjusting member 30, and forming a limiting space 3101 on the side of the limiting part 31 away from the second end of the adjusting member 30, and simultaneously providing a mating part 50 on the seat 10, the mating part 50 is adapted to the limiting part 31 and accommodated within the limiting space 3101. In this case, the limiting part 31 and the mating part 50 work together to limit the adjusting member 30 in at least two different directions. This effectively prevents the adjusting member 30 from moving relative to the base cover 112 due to external force when the child safety seat 100 is impacted, thus helping to solve the problem of existing child safety seats 100 easily skipping gears. In particular, when the existing child safety seat 100 is used rear-facing and encounters a rear-facing impact, the limiting part 31 and the mating part 50 can better prevent the adjusting member 30 from skipping gears due to the impact.

[0081] It is necessary to understand that, such as Figure 2 and Figure 4 As shown, a plurality of adjustment holes 221 are formed on the base 20 at intervals along the first direction a. The adjustment member 30 can be disposed on the seat 10, and the adjustment member 30 can be connected to different adjustment holes 221 on the base 20. When the adjustment member 30 is connected to different adjustment holes 221, the relative position of the adjustment member 30 and the base 20 changes, thereby changing the relative position of the seat 10 and the base 20. That is, the seat 10 is movably disposed on the base 20 along the first direction a.

[0082] It is understood that the first direction 'a' can be a straight line or an arc, and this embodiment does not limit this. When the first direction 'a' is a straight line, the adjustment mechanism can adjust the position of the seat 10 relative to the base 20 along the straight line, for example, adjusting the seat 10 to move forward and backward, or to move up and down. In this embodiment, the first direction 'a' is an arc, and in this case, the adjustment member 30 can adjust the position of the seat 10 relative to the base 20 along the arc, for example, adjusting the seat 10 to move forward and backward, to move up and down, or to adjust the angle.

[0083] like Figures 8 to 10 As shown, the bottom of the seat 10 is provided with a main body cover 112 extending along a first direction a. In this embodiment, the adjusting member 30 is provided on the main body cover 112 and is movably connected to the main body cover 112 along the first direction a. At this time, the adjusting member 30 extends along the first direction a. A locking member 40 is provided at the first end of the adjusting member 30. When the adjusting member 30 moves relative to the main body cover 112 along the first direction, it drives the locking member 40 to switch between a locked state and an unlocked state. In the locked state, the locking member can be inserted into one of the multiple adjusting holes 221 to fix the adjusting member 30 to the main body cover 112, thereby realizing the fixed installation of the seat 10 on the base 20. In the unlocked state, the locking member 40 is disengaged from the adjusting hole 221, and the seat 10 is movably connected to the base 20, thereby allowing the position of the seat 10 relative to the base 20 to be adjusted. At this time, the main body cover 112, the adjusting member 30, and the locking member 40 work together to form an adjusting mechanism for adjusting the position of the seat 10 relative to the base 20.

[0084] It should be noted that when the adjusting member 30 moves relative to the bottom cover 112 along the first direction a, it drives the locking member 40 to move. At this time, the locking member 40 can move in a straight line or rotate, as long as it can be inserted into or disengaged from the adjusting hole 221. The specific structure is not limited here.

[0085] What needs further understanding is, such as Figure 10 , Figure 12 and Figure 13As shown, the second end of the adjusting member 30 is provided with a limiting part 31, which includes a first limiting arm 311 and a second limiting arm 312. The first limiting arm 311 and the second limiting arm 312 are arranged at an angle to form a limiting space 3101, and the extension directions of the first limiting arm 311 and the second limiting arm 312 both intersect with the first direction a. Meanwhile, a mating member 50 is provided on the seat 10. Along the first direction a, the mating member 50 is located on the side of the limiting part 31 away from the first end. At this time, the mating member 50 is adapted to the limiting part 31 and accommodated within the limiting space 3101. In this embodiment, the mating member 50 is provided on the bottom cover 112 of the main body. Optionally, the mating member 50 and the bottom cover 112 of the main body are integrally formed. This arrangement helps to simplify the structure of the seat 10 and reduce assembly difficulty.

[0086] In addition, the side plate 1121 and the bottom cover 112 of the main body can also be configured as separate structures. In this case, the side plate 1121 and the bottom cover 112 of the main body are connected. The connection method can be screw connection, snap connection and welding connection, etc. This application does not impose any restrictions on this.

[0087] When the adjusting member 30 moves in the positive direction of the first direction a under the operation of the user, the limiting part 31 moves away from the mating member 50. At this time, the mating member 50 will not affect the movement of the adjusting member 30. However, in the event of a collision or sudden deceleration, the seat 10 tends to move relative to the base 20 in the first direction a due to the impact or inertia. At this time, the main body bottom cover 112 tends to move relative to the adjusting member 30 in the first direction a. Simultaneously, the mating member 50 will approach and abut against the limiting part 31 under the action of the seat 10. Since the limiting part 31 is configured with an angled first limiting arm 311 and a second limiting arm 312, and the mating member 50 is adapted to the limiting part 31, the limiting part 31 can apply two opposing forces in different directions to the mating member 50 to restrict the movement of the seat 10, thereby restricting the movement tendency of the main body bottom cover 112 relative to the adjusting member 30, which helps to prevent gear skipping.

[0088] It needs to be further understood that the first limiting arm 311 is located at the second end of the adjusting member 30, extending away from the seat 10. The second limiting arm 312 is located at the end of the first limiting arm 311 away from the adjusting member 30 and extends away from the base 20. This arrangement allows the limiting part 31 to form a limiting space 3101 with a large capacity. Moreover, when the adjusting member 30 moves in the positive direction of the first direction a under the operation of the user, both the first limiting arm 311 and the second limiting arm 312 move away from the seat without being obstructed by the seat.

[0089] In this embodiment, the mating member 50 has a first mating surface 511 and a second mating surface 521. Along the first direction a, the first mating surface 511 and the first limiting arm 311 are spaced apart. The first mating surface 511 is connected to the seat through the second mating surface 521, and the second mating surface 521 and the second limiting arm 312 are spaced apart. At this time, the mating member 50 has a wall surface corresponding to the limiting part 31, which helps to achieve the adaptation between the mating member 50 and the limiting part 31 and improves the accommodation effect of the mating member 50 in the limiting space 3101. When the mating member 50 approaches and abuts against the limiting part 31 under the action of the seat 10, the first mating surface 511 and the first limiting arm 311 abut, and the second mating surface 521 and the second limiting arm 312 abut.

[0090] It is understandable that the mating component 50 can be a solid structure. In this case, the mating component 50 can effectively transmit the reverse force applied by the limiting part 31 to the seat 10, restricting the movement of the seat 10, and also helping to ensure the structural strength of the mating component 50. The mating component 50 can also be an L-shaped plate structure. In this embodiment, the mating component 50 includes a first mating component 51 and a second mating component 52. Both the first mating component 51 and the second mating component 52 are plate structures. The side of the first mating component 51 facing the first limiting arm 311 is the first mating surface 511, and correspondingly, the side of the second mating component 52 facing the second limiting arm 312 is the second mating surface 521. The first mating component 51 is connected to the base 20 through the second mating component 52, thereby connecting the first mating surface 511 and the second mating surface 521 to the seat. This arrangement helps to reduce the weight of the seat 10, achieving lightweight treatment of the seat 10, and also meets the adaptation settings of the mating component 50 and the limiting part 31.

[0091] like Figure 13As shown, the first limiting arm 311 and the second limiting arm 312 have a first included angle α1, where 70°≤α1≤120°. Simultaneously, the extending direction of the first limiting arm 311 has a second included angle α2 with the first direction, where 70°≤α2≤120°. By ensuring that the first included angle α1 between the first limiting arm 311 and the second limiting arm 312 is not less than 70° and not greater than 120°, the first limiting arm 311 and the second limiting arm 312 can be arranged in an approximately perpendicular structure, i.e., an L-shaped structure. Meanwhile, the extension direction of the first limiting arm 311 is made to have a second included angle α2 of not less than 70° and not more than 120° with the first direction, so that the first limiting arm 311 and the adjusting member 30 are approximately perpendicular. On the one hand, this can ensure that when the adjusting member 30 moves relative to the bottom cover 112 along the first direction a, the limiting part 31 will not contact the seat 10, and it helps to reduce the movement distance of the second end of the adjusting member 30. On the other hand, when the limiting part 31 abuts against the seat 10, it can effectively ensure that the limiting part 31 can apply sufficient reverse force to the mating member 50, thereby reducing the component force. Thirdly, it can minimize the extension length of the first limiting arm 311 and the second limiting arm 312 while ensuring that the mating structure of the limiting part 31 and the mating member 50 can be realized.

[0092] Furthermore, a guide rib 3121 is provided on the side of the second limiting arm 312 facing the second mating surface 521.

[0093] Specifically, by providing guide ribs 3121 on the side of the second limiting arm 312 facing the second mating surface 521, not only can the convenience and smoothness of operating the adjusting component 30 be improved and jamming be avoided, but the structural strength of the adjusting component 30 can also be improved and the service life of the adjusting component 30 can be increased.

[0094] like Figure 10 and Figure 13 As shown, a guide rib 3121 is provided on the side of the second limiting arm 312 facing the second mating surface 521, that is, a guide rib 3121 is provided on the side of the second limiting arm 312 facing the seat 10. In this embodiment, two guide ribs 3121 are provided, and they are symmetrically arranged on the second limiting arm 312 along the second direction b. Optionally, one end of the guide rib 3121 is connected to the first limiting arm 311, and the other end smoothly transitions to the end of the second limiting arm 312 opposite to the first limiting arm 311. As a further preferred embodiment, the cross-sectional area of ​​the guide rib 3121 gradually decreases along the extension direction of the second limiting arm 312. At this time, the mating member 50 can move quickly under the guidance of the guide rib 3121 so that the first mating surface 511 and the first limiting arm 311 abut. This arrangement helps to further improve the performance of the adjusting member 30.

[0095] It is necessary to further understand that an operating part 32 is provided on the side of the first limiting arm 311 away from the first mating surface 511. The operating part 32 is located at the end of the first limiting arm 311 away from the adjusting member 30 and extends in the direction away from the second limiting arm 312. At this time, the operating part 32, the first limiting arm 311 and the adjusting member 30 work together to form a handle position for the user to operate at the second end of the adjusting member 30. This helps to further improve the use effect of the first limiting arm 311. Moreover, by forming the handle position at the second end of the adjusting member 30, it helps to reduce the operating intensity of the adjusting member 30, making the movement of the adjusting member 30 relative to the base 20 more effortless and convenient.

[0096] It should be pointed out that, as Figure 13 As shown, since the second limiting arm 312 is also located at the end of the operating part 32 that is away from the first limiting arm 311 and extends towards the seat 10, the second limiting arm 312 and the operating part 32 are located on opposite sides of the first limiting arm 311. This arrangement helps to improve the structural strength of the limiting part 31 and increase the service life of the adjusting part 30.

[0097] like Figures 1 to 4 As shown, the base 20 further includes a base body 21 and a mounting bracket 22. The mounting bracket 22 is disposed on the base body 21 and has a plurality of adjustment holes 221 spaced apart along a first direction a. When the adjustment member 30 moves relative to the bottom cover 112 along the first direction, it drives the locking member 40 to move along the second direction b, so that the locking member can be inserted into or disengaged from the adjustment holes 221. The second direction is parallel to the axis of the adjustment holes 221.

[0098] Specifically, by moving the locking member 40 along the second direction b, which is parallel to the axis of the adjustment hole 221, the cooperation effect between the locking member 40 and the adjustment hole 221 can be maximized, thereby improving the fixing effect between the seat 10 and the base 20 and ensuring the safety of the child safety seat 100.

[0099] It should be understood that the base body 21 is used to abut against a supporting surface, which can be the ground or a car seat cushion. Mounting brackets 22 are mounted on the base body 21. The mounting brackets 22 are plate structures. In this embodiment, there are two mounting brackets 22, spaced apart along a second direction b. Each mounting bracket 22 has multiple adjustment holes 221 spaced apart along a first direction a. The second direction b is parallel to the axis of the adjustment holes 221. In this embodiment, the first direction a is an arc direction, and the first direction a and the second direction b form an angle, with the second direction b intersecting the plane containing the first direction a.

[0100] In this embodiment, the main body cover 112 and the adjusting member 30 of the seat 10 are both housed between two mounting brackets 22, and the locking member 40 is movably disposed on the main body cover 112 along the second direction b. When the adjusting member 30 moves relative to the main body cover 112 along the first direction a, it drives the locking member 40 to move along the second direction b, so that the locking member 40 can be simultaneously inserted into or disengaged from the adjusting holes 221 on the two mounting brackets 22.

[0101] Specifically, the first end of the adjusting member 30 is provided with a guide portion 33. In this embodiment, the guide portion 33 is a groove structure. The extension direction of the guide portion 33 is set at an angle to both the first direction a and the second direction b. The extension direction of the guide portion 33 is a straight line. When the first direction a is an arc, the extension direction of the guide portion 33 intersects with the first direction a, and the extension direction of the guide portion 33 intersects with the plane containing the first direction a. Meanwhile, the locking member 40 is generally set as a columnar structure and extends along the second direction b. The locking member 40 is movably inserted into the bottom cover 112 of the main body. One end of the locking member 40 is provided with a guide post 401 located in the guide portion 33. When the adjusting member 30 moves relative to the bottom cover 112 of the main body along the first direction a, the guide post 401 moves along the second direction b under the guidance of the guide portion 33, so that the locking member 40 can be inserted into or disengaged from different adjusting holes 221.

[0102] Specifically, such as Figures 7 to 11 As shown, when the locking member 40 is in the locked state, the guide post 401 is located in the guide portion 33 of the adjusting member 30 on the side close to the adjusting hole 221, and one end of the locking member 40 is located in the adjusting hole 221; when the locking member 40 is released from the locked state, the guide post 401 is located in the guide portion 33 of the adjusting member 30 on the side away from the adjusting hole 221, and one end of the locking member 40 moves out of the adjusting hole 221.

[0103] More specifically, when the adjusting member 30 moves in the positive direction of the first direction a, the guide post 401, guided by the guide portion 33, can move away from the adjusting hole 221. Simultaneously, it drives the locking member 40 to move away from the adjusting hole 221, causing the locking member 40 to move out of the adjusting hole 221. At this time, the seat 10 can be slid to adjust the angle of the seat 10 relative to the base 20, etc. After adjusting to the desired angle, the adjusting member 30 moves in the negative direction of the first direction a, causing the guide post 401 to return to the side of the guide portion 33 closer to the adjusting hole 221, and one end of the locking member 40 to be located in the adjusting hole 221 corresponding to the desired angle, thus completing the angle adjustment of the child safety seat 100. This configuration simplifies the structure for driving the relative movement of the base 20 and the seat 10, and the working principle is simple and easy to operate, facilitating subsequent inspection and maintenance.

[0104] Furthermore, the mounting bracket 22 has a first sliding groove 222 extending along a first direction a, and the child safety seat 100 also includes a side plate 1121, a first sliding rod 16, and a second sliding rod 23. The side plate 1121 is connected to the bottom cover 112 of the main body and is disposed opposite to the mounting bracket 22. The side plate 1121 has a second sliding groove 11211 extending along the first direction a. The first sliding rod 16 is disposed on the side plate 1121, extends along a second direction, and passes through the first sliding groove 222. The second sliding rod 23 is disposed on the mounting bracket 22, extends along a second direction, and passes through the second sliding groove 11211.

[0105] Specifically, by setting a first sliding groove 222 and a second sliding rod 23 on the mounting bracket 22, and cooperating with the first sliding rod 16 and the second sliding groove 11211 on the side plate 1121, the seat 10 can move relative to the mounting bracket 22 along the first direction a. The structure is simple and the cooperation method is rigorous, which helps to ensure the accuracy and stability of the movement of the seat 10 relative to the base 20.

[0106] It is necessary to understand that, such as Figure 3 and Figure 4 As shown, each of the two mounting brackets 22 is provided with a first sliding groove 222 extending along the first direction a. Simultaneously, a second sliding rod 23 is mounted on both mounting brackets 22, with both ends of the second sliding rod 23 passing through the two mounting brackets 22 and extending outwards. Along the first direction a, the second sliding rod 23 and the first sliding groove 222 are arranged sequentially and at intervals. Optionally, the second sliding rod 23 is located at the front end of the mounting bracket 22, and the first sliding groove 222 is located near the rear end of the mounting bracket 22. The front-rear direction of the mounting bracket 22 is determined according to the usage direction of the child safety seat 100. In this embodiment, the adjustment hole 221 is located on the side of the first sliding groove 222 facing the base body 21, that is, the adjustment hole 221 is located below the first sliding groove 222.

[0107] like Figure 7 and Figure 8As shown, side plates 1121 are provided on opposite sides of the main body bottom cover 112 along the second direction b, and the side plates 1121 are correspondingly arranged with the mounting brackets 22. In this embodiment, the two side plates 1121 are used to be installed between the two mounting brackets 22. Each side plate 1121 is provided with a second sliding groove 11211 extending along the first direction a. At the same time, a first sliding rod 16 is connected between the two side plates 1121, and the two ends of the first sliding rod 16 pass through the two side plates 1121 respectively and extend outward. When the seat 10 is installed on the base 20, the two side plates 1121 are located between the two mounting brackets 22, and the two ends of the first sliding rod 16 are respectively inserted into the two first sliding grooves 222. The two ends of the second sliding rod 23 are respectively inserted into the second sliding grooves 11211.

[0108] It should be noted that in this embodiment, the side panel 1121 and the main body bottom cover 112 are integrally molded parts, which helps to reduce the manufacturing and assembly difficulty of the seat 10 and improve the assembly efficiency of the seat 10. In addition, the side panel 1121 and the main body bottom cover 112 can also be configured as separate structures. For details, please refer to the installation method of the mating part 50 and the main body bottom cover 112 mentioned above, which will not be described in detail here.

[0109] Furthermore, the seat 10 includes a seat body 11, a support tube 12, and a reinforcing plate 13. A bottom cover 112 is disposed at the bottom of the seat body 11. The support tube 12 is disposed inside the seat body 11. The reinforcing plate 13 is disposed on the support tube 12 and corresponds to the side plate 1121. The reinforcing plate 13 has a third sliding groove 131 extending along a first direction, which corresponds to the second sliding groove 11211. A second sliding rod 23 passes through the third sliding groove 131.

[0110] Specifically, by setting a reinforcing plate 13 on the support tube 12, on the one hand, it helps to improve the structural strength of the support tube 12 and ensure the support effect of the support tube 12 on the seat body 11; on the other hand, it realizes the connection of the support tube 12, the reinforcing plate 13, the side plate 1121 and the second sliding rod 23, which helps to improve the load-bearing strength of the second sliding rod 23 when it is subjected to an impact, reduce the horizontal displacement in the forward collision, and improve the anti-collision performance of the child safety seat 100 when used in the forward direction.

[0111] It should be understood that there are two support tubes 12, symmetrically arranged on opposite sides of the bottom cover 112. In this configuration, the seat body 11 encloses the support tubes 12, forming a seat structure for the user to sit on. In this embodiment, the seat body 11 includes a main body 111, a bottom cover 112, a rear cover 113, and a side cover 114. The bottom cover 112, rear cover 113, and side cover 114 are all connected to the main body 111 and form receiving cavities. The support tubes 12 are disposed within these receiving cavities. Optionally, the support tubes 12 are connected to the main body 111. The side cover 114 includes an upper side cover 1141 and a lower side cover 1142, which are respectively connected to the main body 111, thereby enclosing the support tubes 12.

[0112] In this embodiment, the support tube 12 has a movable section 122 extending along a first direction a, and a first section 121 and a second section 123 extending along a straight direction. The first section 121 and the second section 123 are respectively disposed at both ends of the movable section 122, and the length of the first section 121 is less than that of the second section 123, thus corresponding to the support portion and backrest portion of the seat. A reinforcing plate 13 is connected and disposed on the support tube 12, and is located on the side of the support tube 12 facing the side plate 1121. At the same time, a third sliding groove 131 is provided on the reinforcing plate 13, and the third sliding groove 131 is correspondingly disposed with the second sliding groove 11211. When the seat 10 is installed on the base 20, the two ends of the second sliding rod 23 pass through the two second sliding grooves 11211 and then pass through the two third sliding grooves 131 respectively. At this time, the two third sliding grooves 131 can further improve the accuracy and stability of the second sliding rod 23 during movement, and at the same time, can also improve the impact resistance of the front end of the seat 10.

[0113] It should be further understood that the child safety seat 100 also includes a first reinforcing sleeve 14 and a second reinforcing sleeve 15. The first reinforcing sleeve 14 is disposed on the reinforcing plate 13 and sleeved on one end of the first sliding rod 16. For example... Figure 8 , Figure 9 and Figure 14 As shown, there are two first reinforcing sleeves 14, each mounted on one of the two reinforcing plates 13. The first reinforcing sleeves 14 are fixedly connected to the reinforcing plates 13, and the two first reinforcing sleeves 14 are respectively fitted onto both ends of the first sliding rod 16. This arrangement helps to improve the load-bearing strength of the first sliding rod 16 when subjected to impact. Optionally, the first reinforcing sleeves 14 and the third sliding groove 131 are spaced apart along the first direction a.

[0114] Still Figure 14As shown, the second reinforcing sleeve 15 is disposed on the reinforcing plate 13, and the second reinforcing sleeve 15 is located at the end of the third sliding groove 131 opposite to the first reinforcing sleeve 14. The axial direction of the second reinforcing sleeve 15 is parallel to the second direction, and the second reinforcing sleeve 15 has an opening for the second sliding rod 23 to enter. By disposing of the second reinforcing sleeve 15 at the end of the third sliding groove 131 opposite to the first reinforcing sleeve 14, and providing an opening on the second reinforcing sleeve 15 for the second sliding rod 23 to enter, the radial cross-section of the second reinforcing sleeve 15 is approximately semi-circular. In actual use, when the seat is adjusted to the upright position, the second sliding rod 23 moves to the end of the third sliding groove 131 away from the first reinforcing sleeve 14. At this time, the second reinforcing sleeve 15 can cover both ends of the second sliding rod 23, which helps to further improve the load-bearing strength of the second sliding rod 23 when it is impacted. When it is used in the forward direction and is impacted, by setting the first reinforcing sleeve 14 and the second reinforcing sleeve 15 on the reinforcing plate 13, the load-bearing strength of the first sliding rod 16 and the second sliding rod 23 when they are impacted can be further enhanced, thereby further reducing the horizontal displacement of the forward impact and improving the anti-collision performance when used in the forward direction.

[0115] Furthermore, along the extending direction of the support tube 12, there is a first distance L between the front end of the support tube 12 and the seat body 11, where 10mm≤L≤30mm.

[0116] Specifically, by setting a certain distance between the front end of the support tube 12 and the seat body 11 along the extension direction of the support tube 12, a buffer space can be formed between the support tube 12 and the seat body 11 when the child safety seat 100 is impacted, so that the end of the support tube 12 will not hit the seat body 11, thereby reducing the Z-axis chest acceleration and also helping to improve the riding safety of the child safety seat 100.

[0117] It is necessary to understand that, such as Figure 15 As shown, along the extending direction of the first segment 121 of the support tube 12, there is a first distance L between the end of the first segment 121 away from the movable segment 122 and the seat body 11. At this time, the end of the first segment 121 away from the movable segment 122 is the front end of the support tube 12. Optionally, 10mm ≤ L ≤ 30mm. In this embodiment, L is 15mm. The spaced arrangement between the first segment 121 and the seat body 11 creates a buffer space between the front end of the support tube 12 and the seat body 11, helping to prevent the front end of the support tube 12 from impacting the seat body 11, thereby reducing the Z-axis chest acceleration and improving the riding safety of the child safety seat 100.

[0118] It should be noted that, in this embodiment, along the extension direction of the second segment 123 of the support tube 12, the end of the second segment 123 away from the movable segment 122 is spaced apart from the seat body 11, thereby forming a buffer space between the rear end of the support tube 12 and the seat body 11, which helps to prevent the rear end of the support tube 12 from hitting the seat body 11 and helps to improve the riding safety of the child safety seat 100.

[0119] Furthermore, the base body 21 includes a base lower cover 211, the base lower cover 211 includes a lower cover body 2111 and a surrounding plate 2112 disposed around the side of the lower cover body 2111, and the front end of the lower cover body 2111 is provided with a notch 21111 that connects to the surrounding plate 2112.

[0120] Specifically, by setting a notch 21111 at the front end of the lower cover body 2111 and connecting the notch 21111 to the surrounding plate 2112, a certain buffer deformation space is formed between the surrounding plate 2112 and the lower cover body 2111. When encountering an impact, the notch 21111 on the lower cover body 2111 can buffer the impact, thereby reducing the pleural acceleration.

[0121] It should be understood that the base body 21 includes a lower base cover 211 and an upper base cover 212, wherein the aforementioned mounting bracket 22 is disposed on the upper base cover 212. Optionally, the upper base cover 212 and the mounting bracket 22 are integrally formed. The lower cover body 2111 is used to abut against the ground or the seat cushion of a car seat. In this embodiment, the lower base cover 211 includes a lower cover body 2111 and a surrounding plate 2112, wherein the lower cover body 2111 is a cuboid plate structure, and a supporting rib is provided at one end of the lower cover body 2111 away from the upper base cover 212. At the same time, a surrounding plate 2112 is provided at the edge of the lower cover body 2111, and the length of the surrounding plate 2112 is the same as that of the supporting rib in the vertical direction. The surrounding plate 2112 helps to improve the structural strength of the base body 21 and ensure the supporting effect of the base body 21.

[0122] like Figure 16 As shown, along the third direction c, the front end of the lower cover body 2111 is provided with a notch 21111. At this time, the front end of the lower cover body 2111 is the end from which the occupant is away from the backrest. There are two notches 21111, and the two notches 21111 are symmetrically arranged at both ends of the lower cover body 2111 along the second direction b. In this embodiment, the notch 21111 is located at the front end of the lower cover body 2111 and at a corner of the lower cover body 2111. The notch 21111 is connected to the surrounding panel 2112 so that when the surrounding panel 2112 is impacted, the notch 21111 on the lower cover body 2111 can buffer the deformation of the surrounding panel 2112, thereby reducing the synergistic acceleration of the thoracic cavity.

[0123] What needs further understanding is, such as Figure 17 and Figure 18 As shown, a support plate 21112 is provided on the side of the lower cover body 2111 away from the seat 10. Along the third direction c, the support plate 21112 is located on one side of the notch 21111 and extends towards the other side. The support plate 21112 and the surrounding plate 2112 are spaced apart. In this embodiment, the support plate 21112 is provided on the side of the lower cover body 2111 away from the seat 10. The support plate 21112 and the lower cover body 2111 are integrally formed. Along the third direction c, the support plate 21112 is located on one side of the notch 21111 and extends towards the adjacent surrounding plate 2112, and there is a certain distance between the support plate 2112 and the surrounding plate 2112. When the enclosure 2112 is impacted and moves toward the lower cover body 2111, the notch 21111 can buffer the deformation of the enclosure 2112. At this time, the support plate 21112 can provide auxiliary support for the deformation of the enclosure 2112, so as to further limit the deformation of the enclosure 2112 and help to further reduce the thoracic cavity composite acceleration.

[0124] The child safety seat 100 of this application, by providing a limiting part 31 and a mating part 50, makes it less likely to jump out of gear when subjected to external impact. By adjusting the distance between one end of the support tube 12 and the seat body 11, and by providing a notch 21111 on the lower cover 211 of the base body 21, the child safety seat 100 has a certain buffer space when subjected to impact, which helps to improve the impact resistance of the child safety seat 100 and protect the occupant. At the same time, it can further reduce the impact force on the base 20 or the seat 10, and together with the aforementioned limiting part 31 and mating part 50, further prevents jumping out of gear.

[0125] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
