Description

Technical Field

[0001] This utility model relates to a seat belt insertion device, and more particularly to an automatic seat belt pushing device. Background Technology

[0002] Most existing car seat belts require manual fastening, which is cumbersome and affects the user experience. Inserting the buckle requires manual searching, especially in dim lighting where passengers have to bend over or turn to find it. To solve these problems, automatic seat belt insertion devices have emerged, such as the fully automatic car seat belt disclosed in Chinese Patent CN106985785A. This device includes a retractor, a insert plate, a buckle, and webbing. Both ends of the webbing are fixed to the seat on the side away from the door, with one end fixed to the retractor. The retractor is installed on the side of the seat away from the door, and the buckle is installed on the side of the seat closer to the door. The seat belt also has a telescopic bar with webbing loops that allow the webbing to move freely through them. The length of the telescopic bar is controlled by a power source and can vary within a certain range. The insert plate is fixed to one end of the telescopic bar, and the other end is fixed to the car. Extending or retracting the telescopic bar towards the buckle inserts the insert plate into the buckle. Although this fully automatic car seat belt achieves automatic seat belt insertion, its use of a hydraulic cylinder for the telescopic rod results in a relatively complex overall structure and occupies a large amount of space. In actual use, it is quite inconvenient, affecting the movement space of the driver and passengers, and may even pose a safety hazard. Utility Model Content

[0003] To address the aforementioned problems of complex structure, large space occupation, poor practicality, and safety hazards, this utility model provides an automatic seat belt pusher, the specific technical solution of which is as follows: An automatic seat belt pusher includes: a telescopic base with a telescopic groove and a guide groove communicating with the telescopic groove; a telescopic wheel rotatably disposed within the telescopic groove; a telescopic motor disposed on the telescopic base and connected to the telescopic wheel; a telescopic steel belt movably disposed within the telescopic groove and the guide groove and wound around the telescopic wheel, one end of the telescopic steel belt being disposed on the telescopic wheel; a telescopic track, one end of which is disposed on the telescopic base and includes a plurality of telescopic sleeves sequentially sleeved to achieve telescopic extension and retraction along an arc; and a first fixed seat disposed at the other end of the telescopic track for engaging with a locking tongue; wherein the telescopic steel belt is also movably disposed within the telescopic track, and the other end of the telescopic steel belt is connected to the other end of the telescopic track for pushing the telescopic track to extend and retract.

[0004] Preferably, the telescopic steel belt is an arc-shaped steel belt.

[0005] Preferably, the telescopic sleeve is provided with a steel strip groove, and the telescopic steel strip is inserted into the steel strip groove.

[0006] Furthermore, the steel strip groove is provided at the end of the telescopic sleeve.

[0007] Preferably, the automatic seat belt pushing device further includes a bearing, which is disposed in the telescopic groove and movably abuts against the telescopic steel belt.

[0008] Preferably, the first fixing seat is provided with a first fixing groove for locking the locking tongue.

[0009] Furthermore, the first fixing base is provided with a first strong magnet for attracting the locking tongue to the first fixing base.

[0010] Compared with the prior art, the present invention has the following beneficial effects: The automatic seat belt pusher provided by this utility model reduces the size by using a telescopic track, making the structure compact. It only needs to be installed at the bottom of the seat and is in a retracted state when not in use, so it does not affect the activity space of the driver and passengers. It is practical and improves safety. The telescopic steel belt is also compacted by winding, reducing the overall size. Attached Figure Description

[0012] The present invention will now be further described with reference to the accompanying drawings.

[0013] like Figures 1 to 8As shown, an automatic seat belt pusher includes a telescopic base 1, a telescopic wheel 21, a telescopic motor 22, a telescopic steel belt 3, a telescopic track 4, and a first fixed base 51. The telescopic base 1 has a telescopic groove 11 and a guide groove 12 inside, and the guide groove 12 communicates with the telescopic groove 11. The telescopic motor 22 is fixed on the telescopic base 1, and the motor shaft of the telescopic motor 22 is connected to the telescopic wheel 21 to drive the telescopic wheel 21 to rotate. The telescopic wheel 21 is movably located in the telescopic groove 11. One end of the telescopic steel belt 3 is fixed to the telescopic wheel 21 and wound around the telescopic wheel 21. The telescopic track 4 includes a plurality of telescopic sleeves 41 that are sequentially sleeved to achieve telescopic extension and retraction along an arc. One end of the telescopic track 4 is fixed to the telescopic base 1 and is arranged opposite to the guide groove 12. The other end of the telescopic track 4 is connected to the first fixed base 51, which is used to lock onto the locking tongue 91 so as to drive the locking tongue 91 to move. The telescopic steel belt 3 is also movably inserted into the telescopic track 4, and the other end of the telescopic steel belt 3 is connected to the other end of the telescopic track 4 to push the telescopic track 4 to extend and retract.

[0014] The cross-section of the telescopic sleeve 41 can be circular, elliptical, polygonal, etc. The telescopic sleeve 41 has a certain curvature and is generally arc-shaped. The diameter of the telescopic sleeves 41 that are successively fitted together decreases in succession, and the adjacent telescopic sleeves 41 are clearance-fitted, allowing them to expand and contract freely.

[0015] When the telescopic motor 22 rotates forward, the telescopic wheel 21 releases the telescopic steel belt 3. Under the action of the guide groove 12, the telescopic steel belt 3 extends towards the telescopic track 4, thereby causing the telescopic sleeve 41 to extend. The first fixed seat 51 at the end of the telescopic track 4 causes the locking tongue 91 to move to the buckle, and the locking tongue 91 causes the seat belt to be automatically pulled out. When the arc-shaped telescopic track 4 extends, it can form a semi-circle in front of the seat, thereby moving the locking tongue 91 from one side of the seat to the other side and inserting the locking tongue 91 into the buckle on the other side of the seat.

[0016] The telescopic wheel 21, the telescopic motor 22, and the telescopic steel belt 3 form a retractor structure, which enables the extension and retraction of the telescopic steel belt 3, and drives the extension and retraction of the telescopic track 4 through the telescopic steel belt 3.

[0017] Because the telescopic steel belt 3 is wound around the telescopic wheel 21, it occupies little space, while the telescopic track 4 can extend and retract, so as not to occupy the space around the seat when not in use, and not to affect the movement of the driver and passengers. To prevent the steel strip from bending and to increase the ejection force, the telescopic steel strip 3 is an arc-shaped steel strip.

[0018] To further improve the stability of the telescopic steel belt 3 and ensure it remains unidirectional and does not bend, the telescopic sleeve 41 is provided with a steel belt groove 48. The telescopic steel belt 3 is inserted into the steel belt groove 48. When the telescopic track 4 extends, each telescopic sleeve 41 can support the telescopic steel belt 3, thus ensuring that the telescopic steel belt 3 is not easily bent during the entire extension stroke and maintains high strength to guarantee reliable ejection force, allowing the telescopic track 4 to extend and retract smoothly. The steel belt groove 48 is located on a fixed baffle 49, which is located at the end of the telescopic sleeve 41. This not only facilitates the fixing of the telescopic steel belt 3 but also improves the strength of the telescopic sleeve 41.

[0019] The automatic seatbelt extension device also includes a bearing 23, which is installed inside the telescopic groove 11 and movably abuts against the telescopic steel belt 3. The bearing 23 can reduce the friction between the telescopic steel belt 3 and the side wall of the telescopic groove 11, so that the telescopic steel belt 3 can extend and retract smoothly. Among them, multiple bearings 23 are arranged in a circular array along the axis of the telescopic wheel 21.

[0020] In order to facilitate the locking of the first fixing seat 51 into the locking tongue 91, the first fixing seat 51 is provided with a first fixing groove 511. The first fixing groove 511 matches the locking tongue 91 and can drive the locking tongue 91 to move.

[0021] To prevent the locking tongue 91 from falling off and to improve the reliability and stability of the locking tongue 91 being secured to the first fixed seat 51, a first strong magnet is provided on the first fixed seat 51. The first strong magnet is positioned opposite to the locking tongue 91 so that the locking tongue 91 is magnetically attracted to the first fixed seat 51, ensuring that the locking tongue 91 remains within the first fixed seat 51 and does not fall off when the automatic seat belt pusher moves the locking tongue 91.

[0022] Compared to hydraulic drive, the telescopic steel belt 3, telescopic motor 22, and telescopic wheel 21 have a simpler structure and are easier to control, requiring no complex piping.

[0023] When retracted, the telescopic rail 4 is positioned to the side of the seat, without protruding from the seat or affecting the movement of the driver and passengers. It occupies little space, is easy to use, and is highly practical. Furthermore, its location on both sides of the seat effectively improves safety.

[0024] like Figure 9 and Figure 10As shown, to improve reliability, automatic seatbelt pushers can be installed on both sides of the seat. The two automatic pushers are joined in the middle of the seat, thereby reducing the length of each telescopic track 4 and improving the stability of the telescopic track 4. This solves the problems of easy deformation caused by excessive length of telescopic track 4 and insufficient strength when the steel belt is long. Another automatic seatbelt pusher is equipped with a second fixing seat, which has a second strong magnet. The magnetic force of the second strong magnet is greater than that of the first strong magnet on the first fixing seat 51, so that when the first fixing seat and the second fixing seat are in contact and then separated, the locking tongue 91 can separate from the first fixing seat 51. The locking tongue 91 moves with the second fixing seat. When the other automatic seatbelt pusher drives the locking tongue 91 to retract above the buckle, the buckle automatically inserts into the locking tongue, realizing the locking tongue's fixation and completing the automatic buckling of the seatbelt.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
