[0046] In this embodiment, the mounting plate 21 is concavely provided with a snap-fit ​​groove 2111, and the groove wall of the snap-fit ​​groove 2111 is abutted, and the groove wall of the anti-collision groove 13 covers the notch of the snap-fit ​​groove 2111. It can be understood that the side of the mounting plate 21 is connected so that the snap-fit ​​portion 221 limited in the snap-fit ​​cavity is connected with the enclosing portion 222.

[0047] Optionally, the depth of the engaging groove 2111 is consistent with the thickness of the engaging portion 221 , so that when the engaging portion 221 is limited in the engaging groove 2111 , the first surface 211 of the mounting plate 21 is in a flush state, so as to increase the integrity and aesthetics of the connecting component 2 .

[0048] In one embodiment of the present invention, Figure 4 As shown, the mounting plate 21 is provided with a snap-in hole 2113 and a connecting channel 2112 connecting the snap-in hole 2113 and the snap-in groove 2111. The buckle 22 also includes a snap-in protrusion 223 connected to the snap-in portion 221 at one end away from the enclosing portion 222. The snap-in protrusion 223 passes through the connecting channel 2112 and is limited in the snap-in hole 2113.

[0049] In this embodiment, when the engaging portion 221 extends into the engaging groove 2111, the protruding portion 223 provided at the end of the engaging portion 221 passes through the communicating channel 2112 and is limited in the engaging hole 2113, so that the buckle 22 and the mounting plate 21 are engaged with each other. When replacing a buckle 22 of a different type, it is only necessary to push the protruding portion 223 out of the engaging hole 2113 to realize the removal of the buckle 22.

[0050] In actual implementation, the end of the clamping protrusion 223 is arranged in an inclined surface, so that the clamping protrusion 223 can be inserted into the connecting channel 2112. At the same time, the clamping protrusion 223 can have a certain elasticity, so that when the clamping protrusion 223 extends into the connecting hole 2113 through the connecting channel 2112, it can rebound and be confined in the connecting hole 2113. It can be understood that the clamping protrusion 223 and the engaging portion 221 are surrounded to form a groove, and the outer wall of the connecting channel 2112 is confined in the groove.

When the user collides with the window corner, since the window corner anti-collision device 100 itself is made of flexible material, it will deform and sink toward the window corner while reducing the collision damage to the user. When the collision force is large, the buffering protrusion 112 gradually approaches the window corner side wall 31 under the influence of the above deformation and abuts against the window corner side wall 31, thereby reducing the deformation of the first side wall 11 of the window corner anti-collision device 100. When the collision force is sufficient to make the first side wall 11 sink into contact with the window corner side wall 31, the buffering protrusion 112 further buffers the collision, thereby reducing the degree of deformation of the window corner anti-collision device 100 after the collision, thereby improving the anti-collision effect of the anti-collision device and reducing the collision damage to the user.

[0062] In actual implementation, a plurality of buffer protrusions 112 may be provided, and the buffer protrusions 112 may be made of a flexible material or an elastic material, such as a rubber material or a spring, etc., which is not specifically limited here.

[0063] In an embodiment of the present invention, the mounting plate 21 has a first surface 211 and a second surface 212 that are separated from each other. The engaging portion is detachably connected to the first surface 211 .
