Description

Technical Field

[0001] The present invention relates to the technical field of carriers for infants, and more particularly to child safety seats.

Background Art

[0002] A child safety seat is a device placed on an automobile seat to protect an infant, and restrains the infant by a restraint device. When an emergency braking or an unexpected collision occurs in an automobile, the child safety seat mitigates the impact force on the infant through its casing, restricts the physical movement of the infant through the restraint device, reduces the probability of injury to the infant caused by an accident, and ensures the riding safety of the infant.

[0003] Normally, a side impact protection structure protruding horizontally is also installed on the side wing of a child safety seat. When a side collision occurs to an automobile, the side wing of the child safety seat and the side impact protection structure installed thereon buffer the impact, protecting the body and head of the infant. However, the side impact protection structure installed on the side wing occupies a large amount of horizontal space, which is inconvenient for storing the child safety seat.

[0004] Therefore, there is a need to provide a removable side impact protection block that can be selectively attached according to the user's needs.

[0036] Embodiments of the present invention will be described below with reference to the drawings. The same element number in different drawings represents the same element.

[0037] First, referring to Figures 1 to 4, the child safety seat 1 of the present invention includes a seat body (not numbered), two side wings 100 provided opposite the seat body, and removable side impact protection blocks 200 that are removablely attached to the side wings 100. When in use, the removable side impact protection blocks 200 are selectively attached to at least one side wing 100. The attached removable side impact protection blocks 200 protrude from the surface of the side wing 100, as shown in Figures 1 and 3. Thus, in the event of a side impact, the removable side impact protection blocks 200 will collide with the vehicle body or other objects, cushioning the impact force and providing better protection. When it is not necessary to use the removable side impact protection blocks 200, they can be removed from the side wings 100, as shown in Figures 2 and 4, reducing the side space they occupy.

[0038] Furthermore, the removable side impact protection block 200 is not limited to being attached to the side wing 100, but may be attached to other locations on the child safety seat 1. For example, in one embodiment, the removable side impact protection block 200 is selectively attached to a base, and the seat body is attached to the base.

[0039] Referring below to Figures 4 to 7, in the child safety seat 1 of the present invention, a fixed seat 110 is fixed to each side wing 100, and the fixed seat 110 is fixed to the side wing 100 with screws or other connecting parts, although the fixing method is not limited thereto, and a housing groove 111 is provided in the fixed seat 110, the depth of the housing groove 111 is greater than 1 cm, and a removable side impact protection block 200 is detachably inserted and connected to the housing groove 111 of the fixed seat 110, and in the inserted and connected state it protrudes from the surface of the side wing 100.

[0040] As shown in Figures 8-12, 14, and 17, one end of the removable side impact protection block 200 forms an insertion connection end 200a, and the other end forms a stress end 200b. Furthermore, the inner diameter of the housing groove 111 of the fixed seat 110 is greater than or equal to the outer diameter of the insertion connection end 200a, in which case the insertion connection end 200a is ensured to be removablely inserted and connected to the housing groove 111, and when in the inserted and connected state, the stress end 200b protrudes from the surface of the side wing 100.

[0041] More preferably, the shape of the accommodating groove 111 is set to correspond to the shape of the insertion connection end 200a, and the shapes of both may be regular or irregular. The inner diameter of the accommodating groove 111 is slightly larger than the outer diameter of the insertion connection end 200a. In this way, the insertion connection end 200a inserted into the accommodating groove 111 does not wobble, ensuring a stable connection and further mitigating the impact force when the removable side impact protection block 200 is subjected to impact, thereby ensuring the safety of the child safety seat.

[0042] Referring to Figures 4 to 7, more preferably, the side wall of the fixed seat 110 is further provided with a lock hole 112 communicating with the housing groove 111, and the insertion connection end 200a of the removable side impact protection block 200 is detachably engaged and connected to the lock hole 112 after being inserted and connected to the housing groove 111. Furthermore, lock holes 112 may be provided on the two opposing side walls of the fixed seat 110, with at least one lock hole 112 provided on each side wall. In this way, the removable side impact protection block 200 is engaged and connected to at least one lock hole 112 after being inserted and connected to the housing groove 111, enabling mounting of the removable side impact protection block 200 on both sides (details described later) and making the connection more convenient and stable.

[0043] Referring to Figures 5 to 7, in one embodiment of the present invention, locking holes 112 are provided in two side walls in the width direction of the fixed seat 110, with one locking hole 112 provided in each side wall, and furthermore, the locking holes 112 of the two side walls face each other, so that the removable side impact protection block 200 can be selectively engaged and connected to at least one locking hole 112.

[0044] In other embodiments of the present invention, the child safety seat 1 may have a different design, but the installation method of the side wings 100 and the fixed seat 110 is the same in all cases, and the structure of the other parts is all the same as the usual installation method known to those skilled in the art, so a detailed explanation is omitted.

[0045] Referring to Figures 1 to 24, the removable side impact protection block 200 in the present invention includes a protection block 210 and at least one locking component 220, the protection block 210 being detachably inserted and connected to a housing groove 111, and each locking component 220 being provided between the protection block 210 and a fixed seat 110, allowing the protection block 210 to be locked and unlocked to the fixed seat 110.

[0046] In a preferred embodiment of the present invention, the removable side impact protection block 200 further includes an operating part 230 and a first elastic part 240. Here, each locking part 220 is pivotally mounted on the protection block 210 and can move between a locked position and an unlocked position, and the locking part 220 is used to be detachably engaged and connected to a lock hole 112. The operating part 230 is connected to the locking part 220 and pivots the locking part 220 to move between a locked position and an unlocked position, and the first elastic part 240 is mounted on the protection block 210 and abuts against the locking part 220 or the operating part 230 to return the locking part 220 to its original position. When the removable side impact protection block 200 is attached to the side wing 100, the protection block 210 is inserted and connected to the housing groove 111 of the fixed seat 110, the locking component 220 is engaged and connected to the lock hole 112 by the first elastic component 240 to achieve positioning, the other end of the protection block 210 protrudes from the surface of the side wing 100 to become the stress end in the event of impact, the operating component 230 drives the locking component 220 to resist the force acting on the first elastic component 240, disengaging the locking component 220 from the lock hole 112, removing the protection block 210 from the fixed seat 110, and achieving the removal of the entire removable side impact protection block 200.

[0047] Specifically, each locking component 220 has at least one locking hook 221, the locking hook 221 having opposing first and second positions, and when the locking hook 221 is in the first position it protrudes from the protective block 210, at which point the locking hook 221 engages with the locking hole 112, and when the locking hook 221 moves to the second position it is housed in the protective block 210, at which point the protective block 210 moves relative to the fixed seat 110, thereby inserting and connecting the protective block 210 into the housing groove 111 or removing it from the fixed seat 110. In addition, the first elastic component 240 always has a tendency to move the locking hook 221 to the first position.

[0048] As shown in Figures 5 to 24, the removable side impact protection block 200 of the present invention further includes an outer casing 250, which covers the outside of the protection block 210 and exposes the operating parts 230 and lock hook 221 to the outer casing 250, which gives the external shape of the removable side impact protection block 200 a simple and aesthetic appearance and ensures the overall aesthetic appearance of the child safety seat 1 during use.

[0049] In different embodiments of the present invention, the configuration of the removable side impact protection block 200 differs slightly, and the different details of the removable side impact protection block 200 in the different embodiments will be described below with reference to Figures 7-24.

[0050] As shown in Figures 8 to 10, in a first embodiment of the present invention, the removable side impact protection block 200 has a locking component 220 and a locking hook 221, and further, the lower end of the protection block 210 forms an insertion connection end 200a, and one end of the locking component 220 is pivotally attached to the protection block 210, with the locking hook 221 protruding from the other end, and the locking hook 221 is located at the insertion connection end 200a of the protection block 210. The operating component 230 and the locking component 220 are coaxially pivoted and connected to the locking component 220, the operating component 230 protrudes from the protection block 210 and the outer casing 250, and when the operating component 230 is subjected to force and moves, the locking component 220 is pivoted, causing the locking hook 221 to move between a first position and a second position. Furthermore, a positioning structure is provided on at least one of the protective block 210, locking component 220, and operating component 230, and one end of the first elastic component 240 is attached to the positioning structure and abuts against it, thereby ensuring the stability of the mounting of the first elastic component 240.

[0051] Specifically, the operating part 230 is fixed to approximately the center of the locking part 220 and protrudes from the protective block 210 and the outer casing 250, so that when the operating part 230 is subjected to force, it pivots the locking part 220. More preferably, the operating part 230, the lock hook 221, and the locking part 220 are formed integrally, but are not limited to this, and the operating part 230 and the lock hook 221 may be formed separately and then fixed to the locking part 220.

[0052] As shown in Figures 9 to 10, a mounting groove 211 is provided in the protective block 210, a locking component 220 is housed in the mounting groove 211, and its upper end is pivotally attached to the protective block 210. Furthermore, a positioning structure is provided in the operating component 230 and the protective block 210, respectively, and it is preferable that the positioning structure is a positioning projection. Specifically, a positioning projection 231 is provided on one side of the operating component 230, and a positioning projection is provided on the side wall of the mounting groove 211. A position-determining projection 212 is provided opposite to 231, and both ends of the first elastic component 240 are fitted onto the position-determining projections 231 and 212 and come into contact with the operating component 230 and the protective block 210, respectively. Therefore, when the operating component 230 receives force and pivots the locking component 220, the first elastic component 240 is pushed and deformed, releasing the operating component 230. After that, the recovery of the first elastic component 240 drives the operating component 230 and returns the locking component 220 to its original position.

[0053] Furthermore, since the locking component 220 is provided with a position-determining projection, and one end of the first elastic component 240 abuts against the locking component 220, the locking component 220 is similarly returned to its original position. In addition, the position-determining structure is not limited to the position-determining projection, but may be, for example, a position-determining recess or other structure.

[0054] Referring below to Figures 5 to 10, in this embodiment, as shown in Figure 8, the insertion connection end 200a of the protective block 210 is provided symmetrically along its lateral centerline M, and the lock hook 221 is located on the insertion connection end 200a and protrudes from its lateral side. Correspondingly, the shape of the housing groove 111 of the fixed seat 110 corresponds to the shape of the insertion connection end 200a, and furthermore, the inner diameter of the housing groove 111 is slightly larger than the outer diameter of the insertion connection end 200a, and lock holes 112 are provided on the two lateral side walls of the fixed seat 110. In this way, the lock hook 221 is inserted and connected to any lock hole 112, and the protective block 210 is inserted and connected to the housing groove 111, realizing the engagement connection between the lock hook 221 and the lock hole 112, thereby enabling mounting of the protective block 210 on both the front and back sides, and making the mounting of the removable side impact protection block 200 more convenient.

[0055] In this embodiment, the removable side impact protection block 200 may consist of two or more locking components 220. If there are two, the two locking components 220 are pivotally attached to the protection block 210, and their locking hooks 221 protrude from two sides in the width direction of the insertion connection end 200a. Similarly, mounting is achieved on both the front and back surfaces of the protection block 210, and the two sides of the mounted protection block 210 engage and connect with the fixing seat 110 to stabilize the connection. If multiple locking components 220 are provided, each locking component 220 is distributed on both sides of the center line, and each locking hook 221 is located on one side in the width direction of the insertion connection end 200a, with the number of locking holes 112 in the fixing seat 110 corresponding to the number of locking hooks 221.

[0056] Referring to Figures 8 to 10, a first through-hole 251 is provided in the outer casing 250 at a position corresponding to the operating part 230, and after the outer casing 250 covers the protective block 210, the operating part 230 is exposed to the outer casing 250 through the first through-hole 251. In this embodiment, after the outer casing 250 covers the protective block 210, its bottom edge is positioned above the lock hook 221, that is, the insertion connection end 200a protrudes to the outside of the outer casing 250. Thus, after the insertion connection end 200a is inserted and connected to the housing groove 111, the bottom edge of the outer casing 250 abuts against the outer edge of the fixing seat 110, ensuring the aesthetic appearance of the connection as shown in Figure 3, and the upper end of the outer casing 250 becomes the stress end 200b. Of course, the protective block 210 may be completely housed within the outer casing 250, in which case the bottom end of the outer casing 250 is inserted and connected to the housing groove 111 as the insertion connection end 200a, and a second through hole is provided in the outer casing 250 at a position corresponding to the lock hook 221, thereby allowing the lock hook 221 to movably protrude from the outer casing 250 through the second through hole and engage and connect with the fixed seat 110.

[0057] Referring to Figures 2 to 10, the child safety seat 1 in the present invention further includes a pop-up shielding component 300, which is retractably mounted in the housing groove 111 and shields the housing groove 111 when the protective block 210 is removed, maintaining consistency and aesthetics of the overall appearance of the side wing 100, as shown in Figures 2, 4, and 6.

[0058] Referring to Figures 5 to 7, the shielding component 300 includes a cover body 310 and a second elastic component 320. The shape of the cover body 310 corresponds to the housing groove 111, and its size is slightly smaller than the inner diameter of the housing groove 111. The cover body 310 is slidably mounted in the housing groove 111, and the second elastic component 320 abuts against the cover body 310 and the bottom wall of the housing groove 111. When the protective block 210 is mounted in the housing groove 111, the cover body 310 is pushed to the bottom of the housing groove 111. When the protective block 210 is removed, the cover body 310 moves to the top of the housing groove 111 due to the action of the second elastic component 320, shielding the housing groove 111.

[0059] Specifically, a locking hook 311 is provided on the side of the cover body 310, and the cover body 310 is slidably engaged and connected to the fixed seat 110 via the locking hook 311. In this embodiment, the locking hook 311 is provided on the side of the cover body 310 corresponding to the lock hole 112, and the locking hook 311 of the cover body 310 is slidably engaged and connected to the lock hole 112 to achieve a sliding connection, thereby simplifying the configuration of the fixed seat 110. When the protective block 210 is attached to the housing groove 111, the cover body 310 is pushed and slid to the bottom of the housing groove 111. In this process, an elastic force is generated that deforms by pressing the second elastic component 320, and after the lock hook 221 engages with the lock hole 112, the elastic force of the second elastic component 320 pushes the cover body 310 and the protective block 210 upward, stably engaging the protective block 210 with the lock hole 112.

[0060] Referring to Figure 7, a position-determining recess 113 is provided in the bottom wall of the housing groove 111, and correspondingly, a position-determining projection 312 is provided on the cover body 310. One end of the second elastic component 320 is housed in the position-determining recess 113, and the other end is fitted onto the position-determining projection 312 and abuts against the cover body 310. Of course, the position-determining projection may be provided in the bottom wall of the housing groove 111, or the position-determining recess may be provided on the cover body 310.

[0061] The principles of attaching and detaching the removable side impact protection block 200 in the embodiment will be explained below with reference to Figures 1 to 10.

[0062] When attaching the removable side impact protection block 200 to the side wing 100 of the child safety seat 1, first, the operating part 230 is pressed to pivot the locking part 220, moving the locking hook 221 to a first position and then housing it in the protection block 210. In this process, the first elastic part 240 is compressed. Next, the locking hook 221 of the protection block 210 is inserted and connected into the housing groove 111 for the locking hole 112. After releasing the operating part 230, the locking part 220 is pivoted back by the action of the first elastic part 240, engaging and connecting the locking hook 221 to the locking hole 112, and the attachment is completed. At this time, as shown in Figures 1 and 3, the stressed end 200b of the removable side impact protection block 200 protrudes from the surface of the side wing 100. As described above, at least one side wing 100 of the child safety seat 1 is attached to the removable side impact protection block 200, depending on the requirements.

[0063] During the process of inserting and connecting the removable side impact protection block 200 to the fixed seat 110, the cover body 310 is pushed to slide against the bottom of the fixed seat 110, and after the protection block 210 is engaged and connected to the lock hole 112, the cover body 310 abuts against the bottom of the fixed seat 110, and the elastic force generated by the compression of the second elastic component 320 pushes the cover body 310 upward, causing the protection block 210 to be stably engaged and connected to the lock hole 112.

[0064] When it is necessary to remove the removable side impact protection block 200 from the side wing 100 of the child safety seat 1, first, the operating part 230 is pressed to pivot the locking part 220, moving the locking hook 221 out of the locking hole 112 and arriving at the second position, at which point the removable side impact protection block 200 is removed from the fixed seat 110. As shown in Figures 4 and 6, after the protection block 210 is removed, the cover body 310 slides upward due to the elastic force of the second elastic part 320 until the locking hook 311 of the cover body 310 contacts the end wall of the locking hole 112, and the cover body 310 shields the housing groove 111 of the fixed seat 110, thereby keeping the side wing 100 clean and beautiful.

[0065] The removable side impact protection block 200 in the present invention is not limited to one locking component 220, and preferred embodiments of two locking components 220 will be described below.

[0066] Referring to Figures 10 to 13, in a second embodiment of the present invention, the difference between the removable side impact protection block 200 and the first embodiment described above is that it has two locking parts 220, each pivotally attached to a mounting groove 211 of the protection block 210, with locking hooks 221 located on opposite sides of the protection block 210, and operating parts 230 connected to each of the two locking parts 220, which are driven synchronously to pivot and unlock, that is, to synchronously move the locking hooks 221 of the two locking parts 220 between a first position and a second position. In this embodiment, the first locking part 220 and the second locking part 220 are driven to move back synchronously via a first elastic part 240.

[0067] For the sake of clarity, the two locking components 220 are denoted as a first locking component 220a and a second locking component 220b. Here, one end of the first locking component 220a is pivotally attached to the protective block 210, and a locking hook 221 is provided at the other end, which protrudes from one side of the protective block 210 in the lateral direction. The approximately central portion of the second locking component 220b is pivotally attached to the protective block 210, and a locking hook 221 is provided at one end thereof, which protrudes from the other side of the protective block 210 in the lateral direction. Preferably, the two locking hooks 221 are arranged symmetrically with respect to the lateral centerline M of the protective block 210. Furthermore, the operating part 230 is pivotally mounted coaxially with the first locking part 220a and protrudes from the protective block 210. The operating part 230 is connected to the first locking part 220a and the second locking part 220b, and when the operating part 230 is subjected to force and moves, it causes the first locking part 220a and the second locking part 220b to pivot synchronously.

[0068] Referring to Figures 10 to 13, the operating part 230 is fixed to the approximate center of the first locking part 220a, or is integrally formed with the first locking part 220a. Furthermore, the operating part 230 has a drive unit 232, which protrudes from the second locking part 220b and is pivotally attached to one end of the second locking part 220b away from the lock hook 221. Thus, when the operating part 230 is pressed, the first locking part 220a is pivoted and its drive unit 232 The drive unit 232 moves, pushing the upper end of the second locking part 220b as it moves, and further rotating the second locking part 220b around its pivot axis. Furthermore, the pivot direction of the second locking part 220b is opposite to the pivot direction of the first locking part 220a, that is, the first locking part 220a and the second locking part 220b are pivoted and brought closer together, and the locking hooks 221 of the first locking part 220a and the second locking part 220b are moved synchronously to the second position. After the operating part 230 is released, the first locking part 220a and the second locking part 220b are moved back synchronously by the action of the first elastic part 240.

[0069] In this embodiment, the installation method of the second locking component 220b simplifies its structure, and the second locking component 220b may be installed in the same structure as the first locking component 220a, which does not affect the engagement connection between the two components and the fixing seat 110.

[0070] Referring to Figures 10 to 13, in this embodiment, position-determining protrusions 222 are provided on the first locking component 220a and the second locking component 220b. Specifically, the position-determining protrusion 222 of the second locking component 220b is provided below its pivot axis. The position-determining protrusion 222 of the first locking component 220a aligns with that of the second locking component 220b, and both ends of the first elastic component 240 are fitted onto the two position-determining protrusions 222 and come into contact with the first locking component 220a and the second locking component 220b. Therefore, in the process of pivoting the first locking component 220a and the second locking component 220b to the unlocked position, the two components come into close proximity and push and deform the first elastic component 240. After releasing the operating component 230, the first elastic component 240 recovers and drives the first locking component 220a and the second locking component 220b to return to their synchronous positions.

[0071] Furthermore, by setting two first elastic components 240 and having them contact the first lock component 220a and the second lock component 220b respectively, the return of the first lock component 220a and the second lock component 220b can be achieved in a similar manner.

[0072] Referring to Figure 12, in this embodiment, the bottom edge of the protective block 210 is positioned symmetrically along its lateral centerline M, and the bottom edge of the protective block 210 forms a regular geometric shape, making the insertion connection of the removable side impact protection block 200 on both the front and back surfaces smoother.

[0073] Referring to Figures 10 to 13, in this embodiment the configuration of the outer casing 250 differs from that of the first embodiment. Specifically, the bottom edge of the outer casing 250 abuts against the bottom edge of the protective block 210, that is, the protective block 210 is completely housed in the outer casing 250, the bottom end of the outer casing 250 forms an insertion connection end 200a, the shape and size of the bottom end of the outer casing 250 corresponds to the housing groove 111 of the fixed seat 110, the top end of the outer casing 250 forms a stress end 200b, and the outer casing 250 is provided with a first through hole 251 and a second through hole 252, the operating part 230 is exposed to the outer casing 250 through the first through hole 251, and the lock hook 221 movably protrudes from the outer casing 250 through the second through hole 252.

[0074] In this embodiment, the structure of the other parts of the removable side impact protection block 200 and the shielding component 300 is the same as in the first embodiment described above, and therefore will not be described here.

[0075] Referring to Figures 14 to 16, the difference between the removable side impact protection block 200 in the third embodiment of the present invention and the second embodiment described above is that the positioning of the first elastic component 240 is different. In this embodiment, the first lock component 220a is provided with a positioning projection 222, and the protection block 210 is provided with a positioning recess 213 corresponding to the positioning projection 222. One end of the first elastic component 240 is fitted onto the positioning projection 222 and abuts against the first lock component 220a, while the other end is housed in the positioning recess 213 and abuts against the protection block 210. Therefore, when the operating component 230 pivots the first lock component 220a, it pushes the first elastic component 240, when the first elastic component 240 recovers, it pushes the first lock component 220a to return to its original position, and the drive unit 232 pushes the second lock component 220 to return to its original position.

[0076] Other components of the removable side impact protection block 200 in this embodiment are the same as those in the second embodiment described above, and therefore will not be described here.

[0077] The principles of attaching and detaching the removable side impact protection block 200 in the second and third embodiments will be explained below with reference to Figures 11 to 16.

[0078] When attaching the removable side impact protection block 200 to the side wing 100, first, the operating part 230 is pressed to pivot the first locking part 220a in the direction indicated by arrow F1 in Figure 13, and the movement of the drive unit 232 of the operating part 230 pivots the second locking part 220b in the direction indicated by arrow F2 in Figure 13, that is, the pivoting directions of the first locking part 220a and the second locking part 220b are opposite, and furthermore, the locking hooks 221 of both are moved to the first position and housed in the outer casing 250, during which the first elastic part 240 is compressed. Next, as shown in Figure 15, the insertion connection end 200a of the outer casing 250 is inserted and connected into the housing groove 111, and after releasing the operating part 230, the first locking part 220a and the second locking part 220b are pivoted in opposing directions by the action of the first elastic part 240, moving each locking hook 221 to the second position and engaging and connecting with the locking hole 112, and the stressed end 200b protrudes from the surface of the side wing. As shown in Figure 15, in the process of inserting and connecting the removable side impact protection block 200 into the fixed seat 110, the cover body 310 is pushed downward, and finally the cover body 310 is pushed to the bottom of the housing groove 111.

[0079] When removing the removable side impact protection block 200, the operating part 230 is pressed to pivot the first locking part 220a and the second locking part 220b in the directions indicated by arrows F1 and F2 in Figure 15, thereby releasing the locks. Each locking hook 221 disengages from the locking hole 112, and at this time, the removable side impact protection block 200 is removed from the fixed seat 110. As shown in Figure 16, after the removable side impact protection block 200 has been removed from the fixed seat 110, the cover body 310 is returned to its original position by the action of the second elastic part 320, shielding the housing groove 111 of the fixed seat 110.

[0080] Referring below to Figures 17 to 24, in the fourth embodiment of the present invention, the removable side impact protection block 200 similarly has two locking components 220, but the method of connecting the operating component 230 and the locking component 220 in this embodiment differs from that of the second and third embodiments described above.

[0081] Referring to Figures 17 to 21, in this embodiment, the configuration of the two locking components 220 is the same, and they are pivotally attached symmetrically to the protective block 210. Furthermore, the locking component 220 and the locking hook 221 are separate structures. Taking one locking component 220 as an example, the approximately central part of the locking component 220 is pivotally attached to the protective block 210, the lower end of the locking component 220 is pivotally attached to the locking hook 221, the locking hook 221 is slide-connected to the protective block 210, the upper end of the locking component 220 abuts against the operating component 230, and when the operating component 230 moves, it pivots the locking component 220, moving the locking hook 221 along the protective block 210 between a first position and a second position.

[0082] Referring to Figures 17 to 21, in this embodiment, a drive unit 232 and a driven unit 223 are provided between the operating part 230 and the locking part 220. When the operating part 230 receives force and moves, the drive unit 232 and the driven unit 223 interact to push the locking part 220 and pivot. Specifically, one end of the operating part 230 is connected to the protective block 210, and the other end has a drive unit 232 protruding in a direction parallel to the axial direction of the pivot axis of the locking part 220, with the side surface of this drive unit 232 forming a drive surface 2321. Correspondingly, a driven unit 223 protrudes from the upper end of the locking part 220, with the driven unit 223 and the lock hook 221 each protruding in opposite directions relative to the body of the locking part 220, and the driven unit 223 is provided with a driven inclined surface 2231 that intersects with the protruding direction of the drive unit 232. When the operating part 230 is subjected to force and moves, its drive unit 232 is driven to move along the driven inclined surface 2231, and the drive unit 2321 gradually acts on the driven inclined surface 2231, pushing the locking part 220 to pivot.

[0083] Referring to Figures 20-21, in this embodiment, after the two locking parts 220 are pivotally attached to the protective block 210, their driven parts 223 are adjacent to each other, and the driven inclined surfaces 2231 of the two driven parts 223 form a V shape. When the drive surface 2321 acts on the driven inclined surfaces 2231, it pushes the two driven parts 22 to move to either side of the drive part 232, thereby pushing the two locking parts 220 to pivot.

[0084] Referring to Figures 17 to 21, in this embodiment, the protective block 210 is provided with a mounting groove 211, and the side wall of the protective block 210 is provided with a pivot hole 214 communicating with the mounting groove 211, a slide slot 215, and a mounting hole 216. The lock component 220 is housed in the mounting groove 211 and pivotally attached to the pivot hole 214. The lock hook 221 is connected to the slide slot 215 and pivotally attached to the lower end of the lock component 220. The operating component 230 is movably mounted in the mounting hole 216, and its drive unit 232 abuts against the driven inclined surface 2231 of the lock component 220.

[0085] In this embodiment, the first elastic component 240 abuts between the two lock hooks 221, specifically, referring to Figure 18, a positioning recess is provided at one end of each lock hook 221, and the end of the first elastic component 240 is housed in the positioning recess, so that when the two lock hooks 221 slide opposite each other, the first elastic component 240 is pressed and deformed, and when the first elastic component 240 recovers, it pushes the two lock hooks 221 to slide in opposite directions to the first position.

[0086] In this embodiment, the connection method between the operating component 230 and the locking component 220 can also be applied to a configuration with only one locking component 220.

[0087] Furthermore, the structure of the outer casing 250 in this embodiment is the same as that of the second and third embodiments described above, and the structure of the shielding component 300 is the same as that of the first embodiment described above, so a description is omitted here.

[0088] The principles of attaching and detaching the removable side impact protection block 200 in the embodiment will be explained below with reference to Figures 17 to 24.

[0089] When attaching the removable side impact protection block 200 to the side wing 100, first, the operating part 230 is pressed to pivot the locking part 220a in the manner shown by arrows F3 and F4 in Figure 18, i.e., the two locking parts 220 pivot in opposite directions, and then the two locking hooks 221 are slid oppositely into the first position and housed in the outer casing 250, during which the first elastic part 240 is compressed. Next, the insertion connection end 200a of the outer casing 250 is inserted and connected into the housing groove 111, and after releasing the operating part 230, the elastic force of the first elastic part 240 pushes the two locking hooks 221 to slide in opposite directions into the second position, as shown in Figure 23, engaging and connecting with the locking hole 112, and the installation is completed. During the process of inserting and connecting the removable side impact protection block 200 to the fixed seat 110, the cover body 310 is moved downward so that the final cover body 310 contacts the bottom of the housing groove 111, as shown in Figure 23.

[0090] When it is necessary to remove the removable side impact protection block 200, the operating part 230 is pressed again to pivot the two locking parts 220 and unlock them until both locking hooks 221 disengage from the locking holes 112, at which point the removable side impact protection block 200 is removed from the fixed seat 110. After the removable side impact protection block 200 is removed from the fixed seat 110, the cover body 310 returns to its original position due to the action of the second elastic part 320, shielding the housing groove 111 of the fixed seat 110.

[0091] The configuration of the removable side impact protection block 200 in the present invention is not limited to the above preferred embodiment. In other embodiments, the locking component 220 may be a magnetic component provided on at least one of the protection block 210 and the fixed seat 110. If a magnetic component is provided on one of the protection block 210 or the fixed seat 110, the other may be made of a material capable of magnetic attraction to the magnetic component. After the protection block 210 is inserted and connected into the housing groove 111, it is attracted to the fixed seat 110 by magnetism. In this case, the protection block 210 can be attached without providing a locking hole 112 in the fixed seat 110.

[0092] Furthermore, magnetic components may be provided on the removable side impact protection block 200 in the first to fourth embodiments described above, that is, magnetic components may be provided on at least one of the protection block 210 and the fixed seat 110 in the embodiments described above, thereby strengthening the connection between the two through magnetic attraction.

[0093] As described above, the removable side impact protection block 200 in the present invention comprises a protection block 210 and at least one locking component 220, the protection block 210 being detachably inserted and / or connected to the side wing and / or base of the child safety seat and protruding from the surface of the insertion position when inserted and connected, and each locking component 220 being provided between the protection block 210 and the child safety seat and being able to lock and / or unlock the protection block to the child safety seat. Thus, the user can selectively attach the protection block 210 to the base and / or at least one side wing 100 as needed for use, ensuring that the child safety seat 1 has sufficient safety when in use, and the removable side impact protection block 200 can be removed when not needed, allowing the child safety seat 1 to occupy a small side space and making it more convenient to use or store.

[0094] In response to this, the child safety seat 1 having the removable side impact protection block 200 has similar technical effects.

[0095] The above disclosures are merely preferred embodiments of the present invention, and of course, this does not limit the scope of the rights of the present invention. Therefore, equivalent variations within the scope of the patent application of the present invention fall within the scope covered by the present invention.
