[0005] A detachable anti-collision module according to an embodiment of this application has at least the following beneficial effects: by providing an anti-collision part and a connecting part, the anti-collision part can be quickly disassembled or installed onto the seat body through the connecting part to absorb the impact force received by the seat body, thereby improving the ease of disassembly and assembly and the safety of use of the detachable anti-collision module; by providing a movable component and a notch, the movable arm can drive the buckle to insert into the notch under the action of the spring, ensuring that the anti-collision part can be stably fixed in the positioning plate, thereby improving the structural stability of the detachable anti-collision module.

[0006] In some embodiments, the movable arm is located above and below the button, and a connecting post is provided at the end of the movable arm near the button. The two ends of the spring are respectively sleeved on the connecting post. By providing the connecting post, it is ensured that pressing the button can drive the movable arm to move, and releasing the button can cause the spring on the connecting post to drive the movable arm to move in the opposite direction, thereby disassembling or fixing the anti-collision part and improving the ease of use of the detachable anti-collision module.

[0007] In some embodiments, a connecting hole is provided at one end of the movable arm near the connecting post, and a protrusion on the button mates with the connecting hole.

[0012] In some embodiments, the first locking block has a triangular cross-section, and the second locking block has a trapezoidal cross-section. The distance from the apex of the first locking block to the bottom of the cavity is less than the distance from the bottom surface of the second locking block to the bottom of the cavity. This structure ensures that after the elastic element pushes the guard plate over the first locking block, the first locking block and the elastic element can continue to push the guard plate over the second locking block, and finally move it to the opening of the cavity, realizing automatic reset of the guard plate and improving the ease of use of the detachable anti-collision module.

[0013] In some embodiments, the connecting portions are symmetrically distributed on both sides of the seat body, and the anti-collision portion is fixed within one of the connecting portions. This structure ensures that the anti-collision portion can be installed in different connecting portions according to actual needs, thereby adjusting the installation position of the anti-collision portion and improving the compatibility and ease of use of the detachable anti-collision module.

[0014] Secondly, embodiments of this application provide a child safety seat, including a detachable anti-collision module as described in the first aspect.

[0015] The detachable anti-collision module and its child safety seat according to the embodiments of this application have at least the following beneficial effects: By setting an anti-collision part and a connecting part, the anti-collision part can be quickly disassembled or installed onto the seat body through the connecting part to absorb the impact force received by the seat body, thereby improving the ease of disassembly and assembly and the safety of use of the child safety seat; by setting a movable component and a notch, the movable arm can drive the buckle to insert into the notch under the action of the spring, ensuring that the anti-collision part can be stably fixed in the positioning plate, thereby improving the structural stability of the child safety seat; by setting a connecting column, it is ensured that the movable arm can be moved by pressing the button, and the spring on the connecting column can drive the movable arm to move in the opposite direction after the button is released, thereby disassembling or fixing the anti-collision part, improving the ease of use of the child safety seat; by setting a connecting hole and a protrusion, it is easy to drive the movable arm to rotate by pressing the button, so that the buckle can be inserted into the notch to fix the anti-collision part, thereby improving the ease of use of the child safety seat; by setting a first locking block and a second locking block, it is prevented that the buckle and the notch will loosen, ensuring the connection stability between the movable arm and the anti-collision part.

[0028] Reference Figures 1 to 8 This utility model embodiment provides a detachable anti-collision module, including: a seat body 100, an anti-collision part 200, and a connecting part 300. The anti-collision part 200 is detachably connected to the seat body 100 through the connecting part 300. The connecting part 300 includes a movable component 310 and a positioning plate 320. The positioning plate 320 has a cavity 321 for accommodating the anti-collision part 200. The movable component 310 includes a button 311, a movable arm 312, and a spring 313. One end of the movable arm 312 is slidably connected to the button 311, and the other end of the movable arm 312 is provided with a buckle 314. One end of the movable arm 312 abuts against the spring 313 so that the buckle 314 reciprocates around the button 311. The anti-collision part 200 has a notch 210. The movable arm 312 passes through the positioning plate 320 through the buckle 314 and is inserted into the notch 210 and fixedly connected to the connecting part 300.

[0029] A detachable anti-collision module according to an embodiment of this application has at least the following beneficial effects: by providing an anti-collision part 200 and a connecting part 300, the anti-collision part 200 can be quickly disassembled or installed onto the seat body 100 through the connecting part 300 to absorb the impact force received by the seat body 100, thereby improving the ease of disassembly and assembly and the safety of use of the detachable anti-collision module; by providing a movable component 310 and a notch 210, the movable arm 312 can drive the buckle 314 to insert into the notch 210 under the action of the spring 313, ensuring that the anti-collision part 200 can be stably fixed in the positioning plate 320, thereby improving the structural stability of the detachable anti-collision module.

[0030] In some embodiments, the movable arm 312 is located above and below the button 311. A connecting post 315 is provided at one end of the movable arm 312 near the button 311, and both ends of the spring 313 are respectively sleeved on the connecting post 315. By providing the connecting post 315, it is ensured that pressing the button 311 can drive the movable arm 312 to move, and releasing the button 311 allows the spring 313 on the connecting post 315 to drive the movable arm 312 to move in the opposite direction, thereby disassembling or fixing the anti-collision part 200 and improving the ease of use of the detachable anti-collision module.

[0031] In some embodiments, the movable arm 312 has a connecting hole 316 at one end near the connecting post 315, and the button 311 has a protrusion 317 that mates with the connecting hole 316. The button 311 is inserted into the connecting hole 316 through the protrusion 317 and slidably connected to the movable arm 312. By providing the connecting hole 316 and the protrusion 317, it is convenient to rotate the movable arm 312 by the button 311, so that the buckle 314 can be inserted into the notch 210 to fix the anti-collision part 200, thereby improving the ease of use of the detachable anti-collision module.

[0032] In some embodiments, the width of the connecting hole 316 gradually increases in the direction approaching the button 311, and the width of the protrusion 317 gradually increases in the direction away from the movable arm 312. This structure ensures that the protrusion 317 can be stably inserted into the connecting hole 316 and drive the movable arm 312 to rotate, improving the ease of disassembly between the anti-collision part 200 and the connecting part 300.

[0033] In some embodiments, the movable arm 312 has a through hole 318 at its center, and the positioning plate 320 has a cover plate 330 on its outer side. The movable arm 312 is fixed in the positioning plate 320 by inserting the cover plate 330 into the through hole 318. By providing the through hole 318 and the cover plate 330, the buckle 314 can be stably rotated around the through hole 318 and quickly enter and exit the notch 210, achieving the effect of quick installation or removal of the anti-collision part 200. In some embodiments, the cover plate 330 has a connecting post 331 that cooperates with the through hole 318. The cover plate 330 is inserted into the through hole 318 through the connecting post 331, so that the movable arm 312 is movably positioned between the seat body 100 and the cover plate 330, ensuring the flexibility of the movable arm 312.

[0034] In some embodiments, a protective plate 340 is further provided inside the cavity 321, and an elastic member is provided between the protective plate 340 and the bottom of the cavity 321; when the anti-collision part 200 moves outside the cavity 321, the elastic member pushes the protective plate 340 to cover the opening of the cavity 321. By providing the protective plate 340, the cavity 321 can be automatically covered, preventing debris from entering the cavity 321 when the anti-collision part 200 is in the disassembled state, thus ensuring the safety and stability of the detachable anti-collision module.

[0035] In some embodiments, the latch 314 includes a first latching block 341 and a second latching block 342, wherein the length direction of the first latching block 341 is perpendicular to the length direction of the second latching block 342. By setting the first latching block 341 and the second latching block 342, the latch 314 is prevented from becoming loose from the notch 210, thus ensuring the connection stability between the movable arm 312 and the anti-collision part 200.

[0036] Reference Figure 8 In some embodiments, the first locking block 341 has a triangular cross-section, and the second locking block 342 has a trapezoidal cross-section. The distance from the apex of the first locking block 341 to the bottom of the cavity 321 is less than the distance from the bottom surface of the second locking block 342 to the bottom of the cavity 321. This structure ensures that after the elastic element pushes the guard plate 340 over the first locking block 341, the first locking block 341 and the elastic element can continue to push the guard plate 340 over the second locking block 342, and finally move to the opening of the cavity 321, realizing the automatic reset of the guard plate 340 and improving the ease of use of the detachable anti-collision module.

[0037] In some embodiments, the bottom of the cavity 321 is provided with a positioning hole 322 that mates with the first locking block 341 and the second locking block 342. The first locking block 341 and the second locking block 342 pass through the positioning hole 322 into the cavity 321 so that the buckle 314 can be stably fixed in the notch 210, thereby improving the connection stability between the movable arm 312 and the anti-collision part 200.

[0038] In some embodiments, the connecting portions 300 are symmetrically distributed on both sides of the seat body 100, and the anti-collision portion 200 is fixed within one of the connecting portions 300. This structure ensures that the anti-collision portion 200 can be installed in different connecting portions 300 according to actual needs, thereby adjusting the installation position of the anti-collision portion 200 and improving the compatibility and ease of use of the detachable anti-collision module.

[0039] In some embodiments, the anti-collision part 200 is provided with honeycomb-shaped buffer holes 220. By providing buffer holes 220, the anti-collision part 200 can quickly absorb impact force, ensuring the protective performance of the detachable anti-collision module.

[0040] In some embodiments, the cross-section of the anti-collision part 200 is a rounded trapezoid. This structure ensures that the anti-collision part 200 can be quickly and stably installed into the cavity 321, improving the installation convenience and structural stability of the detachable anti-collision module.

[0041] Secondly, embodiments of this application provide a child safety seat, including the detachable anti-collision module as described above.

[0042] In the installation process of a detachable anti-collision module according to an embodiment of this application, the user installs the anti-collision part 200 onto the side of the child safety seat facing the nearest door, based on the installation position of the child safety seat. For example, when the child safety seat is installed on the right rear of the car, the anti-collision part 200 is installed onto the right connecting part 300; when the child safety seat is installed on the left rear of the car, the anti-collision part 200 is installed onto the right connecting part 300. After determining the installation position of the anti-collision part 200, by pressing button 311, the protrusion 317 is inserted into the connecting hole 316, pushing the movable arm 312 to rotate around the through hole 318, thereby causing the buckle 314 to move away from the cavity 321 and move along the positioning hole 322 to the outside of the cavity 321; at the same time, the connecting post 315 moves closer, and the spring 313 sleeved on the connecting post 315 is in a compressed state; next, the end of the anti-collision part 200 with the notch 210 is inserted into the positioning plate 320, and the guard plate 340 is pushed so that the guard plate 340 fits against the bottom of the cavity 321, and the buckle 314 is aligned with the positioning hole 322; finally, when button 311 is released, the spring 313 sleeved on the connecting post 315 returns to its original position, causing the movable arm 312 to rotate in the opposite direction around the through hole 318, causing the buckle 314 to move closer to the cavity 321 and move along the positioning hole 322. Move it into cavity 321 and insert it into notch 210 to fix the anti-collision part 200. At this time, the anti-collision part 200 completes rapid positioning and installation. Due to the action of spring 313, buckle 314 remains fixed in notch 210, effectively ensuring the connection stability between the anti-collision part 200 and seat body 100. When it is necessary to remove the anti-collision part 200, press button 311, buckle 314 moves out of positioning hole 322, and pull out the anti-collision part 200; at the same time, elastic element pushes guard plate 340 outward. At this time, the detachable anti-collision module is in the position as follows. Figure 7 The reset process is as shown; after the elastic element pushes the guard plate 340 past the first locking block 341, the first locking block 341 and the elastic element can continue to push the guard plate 340 past the second locking block 342, and finally move to the opening of the cavity 321, realizing the automatic reset of the guard plate 340. At this time, the detachable anti-collision module is in the position shown. Figure 2 The disassembled state is shown. The installation process of the detachable anti-collision module is efficient and controllable, and the anti-collision part 200 can be quickly and stably installed into the connecting part 300, effectively improving the convenience of disassembly and assembly and the structural stability of the detachable anti-collision module.

[0043] In the use of a child safety seat according to an embodiment of this application, the buffer hole 220 on the outer side of the anti-collision part 200 can abut against the car door. When the vehicle is turning or is impacted from the side, the distance between the seat body 100 and the car door decreases, and the anti-collision part 200 deforms, effectively absorbing the pressure exerted on the seat body 100 by the car door. This prevents the seat body 100 from shifting or even falling off when the vehicle is turning or impacted from the side, effectively improving the protective performance of the child safety seat. When the vehicle completes the turn, the anti-collision part 200 returns to its original shape, and the distance between the seat body 100 and the car door returns to its original position, improving the stability of the child safety seat. When it is necessary to move the child safety seat to the other side of the car, simply press button 311 to remove the anti-collision part 200 and install it onto the connecting part 300 on the other side, greatly improving the installation convenience and compatibility of the detachable anti-collision module.

[0044] The detachable anti-collision module and its child safety seat according to this application embodiment, by setting an anti-collision part 200 and a connecting part 300, allows the anti-collision part 200 to be quickly detached or installed onto the seat body 100 via the connecting part 300, thereby absorbing the impact force received by the seat body 100 and improving the ease of installation and removal and the safety of use of the child safety seat; by setting a movable component 310 and a notch 210, the movable arm 312 can drive the buckle 314 to insert into the notch 210 under the action of the spring 313, ensuring that the anti-collision part 200 can be stably fixed in the positioning plate 320, improving the structural stability of the child safety seat; by setting a connecting column 315, it ensures that the anti-collision part 200 can be fixed by pressing... The button 311 can drive the movable arm 312 to move. After the button 311 is released, the spring 313 on the connecting column 315 can drive the movable arm 312 to move in the opposite direction, thereby disassembling or fixing the anti-collision part 200, improving the ease of use of the child safety seat. By setting the connecting hole 316 and the protrusion 317, it is easy to drive the movable arm 312 to rotate by the button 311, so that the buckle 314 can be inserted into the notch 210 to fix the anti-collision part 200, improving the ease of use of the child safety seat. By setting the first locking block 341 and the second locking block 342, it is possible to prevent the buckle 314 from coming loose from the notch 210, ensuring the connection stability between the movable arm 312 and the anti-collision part 200.
