Detailed Implementation

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0021] like Figures 1-4 As shown, a car seat belt retractor fixing plate includes a fixing plate body 1, with a retractor body 2 located on top of the fixing plate body 1. Two positioning frames 3 are fixedly connected to the upper surface of the fixing plate body 1. A mounting groove 4 is formed on the upper surface of the fixing plate body 1, and a positioning component 5 is installed on the inner wall of the mounting groove 4. The positioning component 5 includes two springs 501, both of which are fixedly connected to the inner wall of the mounting groove 4. A positioning block 502 is fixedly connected to the upper end of the two springs 501, with the top of the positioning block 502 located above the fixing plate body 1. Two symmetrical inclined surfaces 505 are formed on the top of the positioning block 502. A positioning groove 6 is formed on the bottom surface of the retractor body 2, and the positioning block 502 is adapted to the positioning groove 6. Three fixing screws 7 are threadedly connected to the inner wall of the retractor body 2, and three mounting screw holes 8 are formed on the upper surface of the fixing plate body 1.

[0022] The retractor body 2, as a core component of the automotive seatbelt system, is responsible for the retraction and extension of the seatbelt and its locking function in emergency situations. The fixing plate body 1 is the foundation for ensuring that the retractor body 2 can be securely installed in a specific position on the vehicle body. Two positioning frames 3 are arranged symmetrically on the left and right sides, and their main function is to initially limit the left and right position of the retractor body 2. The upper surface of the fixing plate body 1 also has a mounting groove 4 to provide installation space for the positioning components 5. Two springs 501 in the positioning assembly 5 are fixedly connected to the inner wall of the mounting groove 4. The upper ends of the two springs 501 are fixedly connected to the positioning block 502. Under normal conditions, the top of the positioning block 502 protrudes above the fixed plate body 1. Two inclined surfaces 505 are symmetrically opened on the top of the positioning block 502. When the retractor body 2 gradually approaches the fixed plate body 1 during installation, the retractor body 2 will contact and press against the inclined surfaces 505 on the top of the positioning block 502. The three fixing screws 7 threaded on the inner wall of the retractor body 2 correspond to the three mounting screw holes 8 opened on the upper surface of the fixed plate body 1, which are used to firmly connect the retractor body 2 and the fixed plate body 1 after positioning is completed.

[0023] The positioning component 5 also includes two guide grooves 503, both of which are formed on the inner wall of the mounting groove 4 and are symmetrically distributed on the left and right sides. Guide sliders 504 are fixedly connected to both sides of the positioning block 502, and the two guide sliders 504 are slidably connected inside the two guide grooves 503. The guide grooves 503 are formed on the inner wall of the mounting groove 4 and are symmetrically distributed on the left and right sides. The guide sliders 504 fixedly connected to the left and right sides of the positioning block 502 are adapted to the two guide grooves 503 and can slide inside the guide grooves 503, providing stable guidance for the movement of the positioning block 502 within the mounting groove 4. This ensures that when the positioning block 502 is squeezed by the retractor body 2, it can slide along a predetermined trajectory towards the bottom of the mounting groove 4.

[0024] The two positioning frames 3 are symmetrically distributed from left to right, and the left and right sides of the retractor body 2 are located inside the two positioning frames 3. This allows for initial positioning of the retractor body 2. During installation, the left and right sides of the retractor body 2 are inserted into the two positioning frames 3, effectively limiting the left-right displacement of the retractor body 2. The three mounting screw holes 8 are triangularly distributed, and the three fixing screws 7 are matched with the three mounting screw holes 8, making the installation of the retractor body 2 more secure.

[0025] The upper surface of the mounting plate body 1 has two sets of mounting screw holes 9, which are symmetrically distributed on the left and right sides. Each set of mounting screw holes 9 has five holes, and each set of mounting screw holes 9 contains two fixing screws 10. The two sets of mounting screw holes 9 on the upper surface of the mounting plate body 1 are redundantly designed. Each set of mounting screw holes 9 has five holes, and the appropriate mounting screw holes 9 can be selected with fixing screws 10 according to the screw hole spacing requirements of different vehicle models, thus improving the versatility of the mounting plate body 1 during installation.

[0026] A rubber pad 11 is fixedly connected to the bottom surface of the fixing plate body 1. Two sets of pre-drilled slots 12 are provided on the upper surface of the rubber pad 11. These two sets of pre-drilled slots 12 correspond to two sets of mounting screw holes 9, and are compatible with the fixing screws 10. The pre-drilled slots 12 on the rubber pad 11 correspond to the mounting screw holes 9, avoiding interference with the installation of the fixing screws 10. During vehicle operation, the rubber pad 11 can absorb high-frequency vibrations, reducing the impact of vehicle bumps on the fixing screws 10.

[0027] Working principle: In use, push the left and right sides of the retractor body 2 into the two symmetrically distributed positioning frames 3 to limit the left and right position of the retractor body 2. During the continuous pushing of the retractor body 2, the retractor body 2 will contact and squeeze the inclined surface 505 on the top of the positioning block 502, thereby applying a squeezing force to the positioning block 502. Under the action of this squeezing force, the positioning block 502 overcomes the elastic force of the spring 501 and slides down along the guide groove 503 through the guide slider 504, thereby compressing the spring 501. When the retractor body 2 continues to move and the positioning block 502 is completely aligned with the positioning groove 6, the elastic force of the spring 501 will push the positioning block 502 upward, so that it can be smoothly locked into the positioning groove 6. At this time, the positioning of the retractor body 2 and the fixing plate body 1 in the front-back direction is completed. Then, the fixing screw 7 and the mounting screw hole 8 are used to fix the fixing plate body 1 and the retractor body 2 to be firmly connected together. When connecting the mounting plate body 1 to the vehicle body, the upper surface of the mounting plate body 1 is provided with two sets of mounting screw holes 9, and each set of mounting screw holes 9 has five screw holes. According to the requirements of the screw hole spacing specifications of different vehicle models, the appropriate mounting screw holes 9 can be selected and matched with the fixing screws 10 for installation, thus completing the installation of the mounting plate body 1.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
