Description

Technical Field

[0001] This utility model relates to the field of automotive seat belt technology, and in particular to an automotive seat belt retractor bracket. Background Technology

[0002] In automotive passive safety systems, seatbelt retractors are core components that ensure occupant safety during collisions. They restrain occupants in their seats by "flexibly extending and retracting during normal driving and quickly locking upon impact," preventing them from being thrown out of the vehicle due to inertia and impacting the interior. Installing the same type of seatbelt retractor on different models can reduce manufacturing costs for automakers.

[0003] Adjust the length of the bracket according to the mounting hole distance of the vehicle model, and fix the sliding part of the bracket with bolts. Install the seat belt retractor on one side of the bracket, and install the bracket inside the center pillar of the vehicle.

[0004] Most existing car seat belt retractor brackets are designed with a fixed size. The installation position and mounting holes of the seat belt retractor are different for different car models, resulting in large differences in the size of the retractor. It is not possible to install the same size seat belt retractor on different car models. Therefore, a new car seat belt retractor bracket is proposed. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example 1 Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention, which provides a car seatbelt retractor bracket, comprising: Mounting plate 1; Adjustment mechanism 2 is located on one side of mounting plate 1. Adjustment mechanism 2 includes an adapter plate 201 located on one side of mounting plate 1. A perforated plate 202 is installed on the top of adapter plate 201. L-shaped blocks 203 are symmetrically arranged on both sides of adapter plate 201. T-shaped blocks 204 are symmetrically arranged on one side of adapter plate 201. Fastening bolts 205 are symmetrically connected inside mounting plate 1.

[0023] Specifically, the mounting plate 1 has symmetrically formed long grooves on both sides that are adapted to the L-shaped blocks 203. The L-shaped blocks 203 are slidably connected inside the long grooves. The mounting plate 1 has symmetrically formed T-shaped grooves on one side that are adapted to the T-shaped blocks 204. The T-shaped blocks 204 are slidably connected inside the T-shaped grooves. Under the action of the T-shaped grooves, during the movement of the adapter plate 201, the two T-shaped blocks 204 slide in the T-shaped grooves, so that the adapter plate 201 moves in the vertical direction, ensuring the stability of the movement of the adapter plate 201.

[0024] Specifically, the mounting plate 1 has symmetrical through holes on one side for use with fastening bolts 205, and the adapter plate 201 has equally distributed and symmetrically arranged threaded holes on one side for use with fastening bolts 205. The fastening bolts 205 pass through the through holes and connect with the threaded holes. After adjusting the extension length of the adapter plate 201 on one side of the mounting plate 1, the fastening bolts 205 pass through the through holes of the mounting plate 1 and connect with the corresponding threaded holes of the adapter plate 201 by rotation, thereby fixing the adapter plate 201 to one side of the mounting plate 1 and increasing the strength between the adapter plate 201 and the mounting plate 1.

[0025] Specifically, the adjustment mechanism 2 also includes several first springs 207 that are evenly distributed and symmetrically arranged inside the mounting plate 1. One end of each first spring 207 is provided with a limiting bead 206 that is adapted to the L-shaped block 203. A circular groove adapted to the limiting bead 206 is evenly distributed on one side of the inner surface of the long groove. The limiting bead 206 is slidably connected inside the circular groove. A slot adapted to the limiting bead 206 is provided on one side of the L-shaped block 203. The limiting bead 206 is movably engaged inside the slot. Under the action of the first spring 207, the corresponding limiting bead 206 is pushed outward, so that the limiting bead 206 is engaged in the slot of the L-shaped block 203. When the adapter plate 201 is not subjected to external force, under the action of the two limiting beads 206, the adapter plate 201 is stabilized at the extended length by the L-shaped block 203, which facilitates the installation of the fastening bolt 205.

[0026] Next, using a wrench, remove the fastening bolt 205 from the corresponding threads of the adapter plate 201 and remove the fastening bolt 205 from the mounting plate 1. Depending on the position of the seat belt retractor installed on the inside of the vehicle's center pillar, pull the adapter plate 201 up or down on one side of the mounting plate 1. During the pulling of the adapter plate 201, the adapter plate 201 moves the perforated plate 202, and the adapter plate 201 moves the two T-blocks 204 and the two L-blocks 203 simultaneously within the mounting plate 1 until the adapter plate 201 is adjusted to be suitable for installation on the mounting plate 1. The length of the inner side of the vehicle's center pillar is sufficient. At this time, under the action of the two horizontally symmetrical first springs 207, the corresponding limit beads 206 are pushed into the corresponding L-shaped blocks 203, so that the adapter plate 201 is stable at this length position. Then, the two fastening bolts 205 are passed through the mounting plate 1 and screwed into the corresponding threaded holes of the adapter plate 201 by rotation, so that the adapter plate 201 and the mounting plate 1 are firmly fixed. The seat belt retractor is placed on one side of the mounting plate 1, and the perforated plate 202 and the bottom of the mounting plate 1 are installed on the inner side of the vehicle's center pillar.

[0027] Example 2 Reference Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The clamping mechanism 3 is disposed inside the mounting plate 1. The clamping mechanism 3 includes a clamping rod 301. T-shaped limiting blocks 302 adapted to the mounting plate 1 are installed at both ends of the clamping rod 301. A second spring 303 is provided on the top of the T-shaped limiting block 302.

[0028] Specifically, a mounting groove 305 is provided on one side of the mounting plate 1. T-shaped slides 304 adapted to the T-shaped limiting block 302 are provided on both sides of the inner surface of the mounting groove 305. The T-shaped limiting block 302 is slidably connected inside the T-shaped slide 304. When the top of the seat belt retractor pushes the clamping rod 301 upward, the seat belt retractor is placed in the mounting groove 305, so that the clamping rod 301 applies a downward pushing force to the seat belt retractor. After stabilizing the seat belt retractor, it is easy to fix it to the mounting plate 1.

[0029] Specifically, a mounting hole 306 is provided on one side of the mounting plate 1, the clamping rod 301 is slidably connected to the inner cavity of the mounting groove 305, and the second spring 303 is located in the inner cavity of the T-shaped slide 304. Under the action of the second spring 303, downward pressure is applied to the T-shaped limiting block 302. Through the cooperation of the clamping rod 301 and the mounting plate 1, the seat belt retractor is clamped and then fixed.

[0030] Next, take the seat belt retractor and place its top into the mounting groove 305. Use the top to push the clamping rod 301 upward. The clamping rod 301 drives the two T-shaped limiting blocks 302 to move in the corresponding T-shaped slides 304. The T-shaped limiting blocks 302 compress the corresponding second springs 303, causing them to deform and locking the bottom of the seat belt retractor into the mounting groove 305, so that its rear side fits against the inner surface of the mounting groove 305 and the bottom of the seat belt retractor is pressed against the bottom of the mounting groove 305. Under the action of the two second springs 303, the corresponding T-shaped limiting blocks 302 are pushed downward. The two T-shaped limiting blocks 302 drive the clamping rod 301 downward, so that the clamping rod 301 applies a downward force to the seat belt retractor. After stabilizing it in the mounting groove 305, take the fixing bolt, pass it through the bottom of the seat belt retractor, and fix it in the mounting hole 306. The installation of the seat belt retractor is now complete.

[0031] Working principle: First, take the seat belt retractor and place its top into the mounting groove 305. Use the top to push the clamping rod 301 upward. The clamping rod 301 drives the two T-shaped limiting blocks 302 to move in the corresponding T-shaped slides 304. The T-shaped limiting blocks 302 compress the corresponding second springs 303, causing them to deform and locking the bottom of the seat belt retractor into the mounting groove 305, so that its rear side fits against the inner surface of the mounting groove 305 and the bottom of the seat belt retractor is pressed against the bottom of the mounting groove 305. Under the action of the two second springs 303, the corresponding T-shaped limiting blocks 302 are pushed downward. The two T-shaped limiting blocks 302 drive the clamping rod 301 downward, so that the clamping rod 301 applies a downward force to the seat belt retractor, stabilizing it in the mounting groove 305. Then, take the fixing bolt, pass it through the bottom of the seat belt retractor, and fix it in the mounting hole 306. Then, use a wrench to loosen the fastening bolt 205 from the corresponding threads of the adapter plate 201. Remove the fastening bolts 205 from the mounting plate 1. Depending on the position of the seat belt retractor on the inside of the vehicle's center pillar, pull the adapter plate 201 up or down on one side of the mounting plate 1. While pulling the adapter plate 201, the adapter plate 201 moves the perforated plate 202. The adapter plate 201 also moves the two T-shaped blocks 204 and the two L-shaped blocks 203 simultaneously within the mounting plate 1 until the adapter plate 201 is adjusted to a suitable length for installation on the inside of the vehicle's center pillar. At this point, under the action of the two horizontally symmetrical first springs 207, the corresponding limit beads 206 are pushed into the corresponding L-shaped blocks 203, stabilizing the adapter plate 201 at this length. Then, the two fastening bolts 205 are passed through the mounting plate 1 and twisted into the corresponding threaded holes of the adapter plate 201 by rotation, firmly fixing the adapter plate 201 to the mounting plate 1. Finally, install the perforated plate 202 and the bottom of the mounting plate 1 on the inside of the vehicle's center pillar.
