DETAILED DESCRIPTION

[0020] The two embodiments of the application will be described in detail below with reference to the accompanying drawings.

[0021] First embodiment:

[0022] Figures 1-4 An impact-resistant front wall mounting bracket is shown, which comprises a mounting frame 1, the outer end of the mounting frame 1 is provided with a protection frame 2, a pair of side ends of the mounting frame 1 are each provided with an arc-shaped groove 3, the inner side wall of the arc-shaped groove 3 is fixedly connected with a curved spring 4, a pair of inner side walls of the protection frame 2 are each fixedly connected with a plug-in block 5, the plug-in block 5 is movably inserted into the interior of the arc-shaped groove 3, one end of the mounting frame 1 close to the protection frame 2 is provided with a rectangular plate 9, one end of the rectangular plate 9 away from the mounting frame 1 is fixedly connected with a chamfer rubber plate 10, a plurality of reinforcing grooves 7 are formed on the outer end of the mounting frame 1, one end of the rectangular plate 9 close to the mounting frame 1 is fixedly connected with a plurality of reinforcing seats 8 movably inserted into the reinforcing grooves 7, one end of the reinforcing seat 8 away from the protection frame 2 is fixedly connected with a compression spring I 6, one end of the compression spring I 6 away from the reinforcing seat 8 is fixedly connected with the inner wall of the reinforcing groove 7, one end of the mounting frame 1 close to the rectangular plate 9 is provided with a horizontal groove 15, the horizontal groove 15 is movably inserted with a spring sheet 14, a pair of plug-in grooves 13 are formed on the inner side wall of the horizontal groove 15, the plug-in groove 13 is movably inserted with a chamfer block 12, in the initial state, the chamfer block 12 close to the arc surface end of the plug-in groove 13 is in contact with the side end of the spring sheet 14;

[0023] The outer end of the reinforcing seat 8 and the compression spring 6 is attached to the inner wall of the reinforcing groove 7, and in the initial state, the compression spring 6 is in a contracted state, and the end of the protective frame 2 away from the mounting frame 1 is provided with a rectangular slot, and the inner part of the rectangular slot is fixedly connected with a buffer rubber plate 11, and in the initial state, the end of the reinforcing seat 8 away from the mounting frame 1 extends out of the reinforcing groove 7, and the outer end of the chamfered rubber plate 10 is in contact with the inner wall of the protective frame 2.

[0024] A plurality of mounting holes are formed in the mounting frame 1, and in use, the mounting frame 1 is mounted and fixed on the automobile front wall by bolts, and when impacted by external objects, the external objects will first push the buffer rubber plate 11 and the protective frame 2 together to move towards the mounting frame 1, at the same time, the protective frame 2 will drive the insertion block 5 to move in the arc-shaped groove 3, and push the curved spring 4 to slide a distance, so that the curved spring 4 is contracted, and under the action of the curved spring 4 and the buffer rubber plate 11, the impact force brought by the external object is buffered;

[0025] With the inside of the protective frame 2 moving towards the mounting frame 1, the inside of the protective frame 2 will extrude the spring sheet 14, so that the both ends of the spring sheet 14 slide in the inner part of the transverse groove 15 and expand, and are inserted between the chamfered block 12 and the insertion groove 13, so as to push the chamfered block 12 out of the insertion groove 13, and make one end of the chamfered block 12 extend out of the transverse groove 15 (as shown in Figure 3 ), and abut against the inner wall of the inwardly moving protective frame 2, so as to improve the strength of the protective frame 2 and the impact resistance of the bracket;

[0026] When the insertion block 5 moves to the arc angle position of the arc-shaped groove 3, due to the shape characteristics of the arc-shaped groove 3, the insertion block 5 will drive the protective frame 2 to move upwardly by a certain distance, and after the protective frame 2 moves upwardly, the limiting effect on the chamfered rubber plate 10 and the rectangular plate 9 will be removed, and under the action of the elastic force of the compression spring 6, the rectangular plate 9 and the chamfered rubber plate 10 have a tendency to move outwardly at the lower side of the protective frame 2 (as shown in Figure 4 ), so as to exert a reverse force on the impact force of the external object, buffer the impact force, and reduce the damage degree of the automobile front wall;

[0027] As described above, when the automobile front wall is impacted by external objects, the reverse forces generated by the curved spring 4, the compression spring 6 and the spring sheet 14 are used to buffer the impact force in multiple ways, so as to disperse the impact energy, the chamfered block 12 is used to support the protective frame 2, the strength of the protective frame 2 for protecting the automobile front wall is optimized, and the impact resistance of the bracket is improved, so that the damage degree of the automobile front wall caused by external impact is smaller.

[0028] Second embodiment:

[0029] The embodiment is based on the first embodiment, and the structure of the plug-in block 5 is specifically provided as follows, so that the fixed connection between the plug-in block 5 and the protective frame 2 in the embodiment 1 is changed into detachable connection.

[0030] Figure 5 The plug-in block 5 includes a threaded pipe 51 and a sliding block 53, a side end of the protective frame 2 is provided with a threaded hole, the threaded pipe 51 is threadedly connected in the threaded hole, one end of the threaded pipe 51 close to the mounting frame 1 is fixedly connected with a threaded head 52, the threaded head 52 is threadedly connected in the sliding block 53, the outer end of the sliding block 53 is fixedly connected with a limiting ring 54, the sliding block 53 is movably arranged in the arc-shaped groove 3, the inner wall of the arc-shaped groove 3 is provided with a limiting groove in active connection with the limiting ring 54, and the stability of the plug-in block 5 during movement can be improved by using the limiting ring 54.

[0031] When the protective frame 2 is damaged and needs to be disassembled, repaired or replaced from the mounting frame 1, the threaded pipe 51 needs to be rotated to drive the threaded head 52 to rotate in the plug-in block 5, until the threaded pipe 51 and the threaded head 52 are taken out from the protective frame 2 and the plug-in block 5 respectively, and finally the protective frame 2 is taken off from the mounting frame 1, so that the operation steps are simple, and the personnel can conveniently repair and replace the protective frame 2.

[0032] In combination with the current actual demand, the above-mentioned embodiments adopted by the application are not limited to the above, various changes made within the knowledge range of the person skilled in the art without departing from the concept of the application still fall within the protection range of the application.
