[0002] A car seat belt is a device used in a car to restrain passengers and drivers to their seats when the car body is hit violently, to prevent injuries caused by impact inertia and other reasons. The seat belt mounting mechanism of existing seat belt assemblies is mostly fixed to the vehicle by bolts, and the seat belt lock is also connected to the mounting mechanism by bolts. Since the vehicle will generate a lot of bumps and vibrations during long-term driving, it is necessary to avoid the bolts from rotating loose due to external forces, otherwise the seat belt will not be able to provide safety protection for the driver. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a car safety belt assembly for the above defects, which can prevent the bolts from self-rotating and loosening due to external forces, and the installation is more firm, which can provide stable and effective safety protection for the driver.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows: a car seat belt assembly comprises a mounting base, a fixing member, a connecting clip, and a seat belt lock head, the fixing member being arranged on the upper surface of the mounting base, the connecting clip being connected to the fixing member through a first fixing bolt, and second fixing bolts for fixing the mounting base to the vehicle are arranged on the mounting bases on both sides of the fixing member, a connecting column is arranged at one end of the first fixing bolt and the second fixing bolt located at the screw head, a limiting block is arranged at one end of the connecting column away from the first fixing bolt and the second fixing bolt, an elastic clamping member with a C-shaped structure is arranged between the first fixing bolt, the second fixing bolt and the limiting block, a receiving hole matching the connecting column is opened inside the elastic clamping member, two flaring parts are symmetrically arranged at the open end of the elastic clamping member, and the spacing between the two flaring parts gradually increases from one side of the open end to the side away from the open end, and a guiding mechanism for the elastic clamping member to horizontally approach or move away from the first fixing bolt and the second fixing bolt is arranged at one end of the first fixing bolt and the second fixing bolt.

[0005] Furthermore, the guiding mechanism includes a guide rail, a driving member, and a connecting block. The guide rail is symmetrically arranged at one end of the first fixing bolt and the second fixing bolt. One end of the connecting block is connected to an end of the elastic clip away from the opening end. The driving member is symmetrically arranged on the connecting block, and the two driving members are respectively slidably connected to the two guide rails.

[0006] Furthermore, sliding grooves are symmetrically provided on both sides of the guide rail, connecting arms are provided on both sides of the bottom end of the driving member, and sliding blocks slidably connected to the sliding grooves are provided on the inner side of the connecting arms.

[0007] Furthermore, the safety belt lock head is arranged on the top of the connecting clip.

[0008] Furthermore, a seat belt lock tongue is arranged on the seat belt lock head.

[0009] The beneficial effects of the utility model are:

[0010] The utility model cooperates with the connection column, the limit block, the elastic clamp, the accommodating hole, the flaring part and the guide mechanism. After the first fixing bolt and the second fixing bolt are connected, the elastic clamp approaches the connection column of the first fixing bolt and the second fixing bolt through the guide mechanism, and the flaring part conflicts with the connection column. As the elastic clamp continues to be pushed forward, the flaring part expands the opening end of the elastic clamp and causes elastic deformation, so that the connection column enters the accommodating hole of the elastic clamp, and the two end surfaces of the elastic clamp conflict with the first fixing bolt, the second fixing bolt and the limit block, and then the elastic clamp is fixed on the first fixing bolt and the second fixing bolt, and the elastic clamp is limited by the guide mechanism and can only move horizontally, so as to limit the axial direction of the first fixing bolt and the second fixing bolt, and then effectively prevent the first fixing bolt and the second fixing bolt from rotating loose due to external force, so that the installation is more firm, and can provide stable and effective safety protection for the driver.

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] Reference Figure 1-5 As shown, the automobile seat belt assembly includes a mounting base 1, a fixing member 2, a connecting clip 3, and a seat belt lock head 4. The fixing member 2 is arranged on the upper surface of the mounting base 1, and the fixing member 2 and the mounting base 1 are integrally formed. The seat belt lock head 4 is arranged on the top of the connecting clip 3, and the seat belt lock head 4 is provided with a seat belt lock tongue 10. The connecting clip 3 is connected to the fixing member 2 through a first fixing bolt 501. The mounting base 1 on both sides of the fixing member 2 is provided with a second fixing bolt 502 for fixing the mounting base 1 to the vehicle. The connecting clip 3 and the mounting base 1 are both provided with grooves matching the first fixing bolt 501 and the second fixing bolt 502, so that after the first fixing bolt 501 and the second fixing bolt 502 are connected, the connecting column 6 and the elastic clamp 8 are in the same plane, and the first fixing bolt 501 and the second fixing bolt 502 are located at one end of the screw head. The connecting column 6 is provided with a limited position at one end away from the first fixing bolt 501 and the second fixing bolt 502. Block 7, an elastic clamp 8 with a C-shaped structure is arranged between the first fixing bolt 501, the second fixing bolt 502 and the limit block 7, and an accommodating hole 801 matching the connecting column 6 is opened inside the elastic clamp 8, and two flared parts 802 are symmetrically arranged at the open end of the elastic clamp 8, and the distance between the two flared parts 802 is smaller than the diameter of the connecting column 6, and the distance between the two flared parts 802 gradually increases from one side of the open end to the side away from the open end. When the elastic clamp 8 is engaged with the connecting column 6, The flared portion 802 first contacts the connecting column 6, and a conical structure is formed between the two flared portions 802. The outer surface of the connecting column 6 squeezes the flared portion 802, causing it to move away from both sides, causing the elastic clip 8 to undergo elastic deformation, and a flare is formed at its open end, allowing the connecting column 6 to enter the accommodating groove 801 of the elastic clip 8, thereby forming a clamping connection between the elastic clip 8 and the connecting column 7, and the two end surfaces of the elastic clip 8 contact the first fixing bolt 501, the second fixing bolt 502, and the limit block 7.

[0020] A guide mechanism is provided at one end of the first fixing bolt 501 and the second fixing bolt 502 for the elastic clamp 8 to move horizontally toward or away from the first fixing bolt 501 and the second fixing bolt 502. The guide mechanism limits the elastic clamp 8 to move only in the horizontal direction. Then the elastic clamp 8 is restricted by the guide mechanism, thereby limiting the axial movement of the first fixing bolt 501 and the second fixing bolt 502, thereby effectively preventing the first fixing bolt 501 and the second fixing bolt 502 from rotating loose toward the outside of the hole due to external force, and the installation is more secure, which can provide stable and effective safety protection for the driver.

[0021] The guiding mechanism includes a guide rail 901, a driving member 902, and a connecting block 903. The guide rail 901 is symmetrically arranged at one end of the first fixing bolt 501 and the second fixing bolt 502. One end of the connecting block 903 is connected to the end of the elastic clamp 8 away from the open end. The driving member 902 is symmetrically arranged on the connecting block 903, and the two driving members 902 are slidingly connected to the two guide rails 901 respectively. The driving member 902 moves back and forth along the guide rail 901, driving the connecting block 903 and the elastic clamp 8 to approach or move away from the connecting column 6, and the guide rail 901 and the driving member 902 form a match, so that the elastic clamp 8 can only approach or move away from the connecting column 6 in the horizontal direction, and limit the axial movement of the elastic clamp 8.

[0022] Slide grooves 904 are symmetrically provided on both sides of the guide rail 901, and connecting arms 905 are provided on both sides of the bottom end of the driving member 902. A slider 906 slidably connected to the slide groove 904 is provided on the inner side of the connecting arm 905. The slider 906 slides along the slide groove 904 to drive the driving member 902 to reciprocate along the guide rail 901.

[0023] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
