Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and specifically relates to a height adjustment device for seat belts. Background Technology

[0002] Seat belts are a key design feature to ensure optimal protection. Their main function is to prevent occupants from being thrown forward due to inertia during a collision or emergency braking, thereby reducing the risk of injury and even saving lives. Seat belts require height adjustment devices (usually located on the B-pillar or shoulder of the seat) to adjust their height for better protection.

[0003] Existing seatbelt height adjustment devices allow users to change the position of the shoulder strap anchor point by sliding an adjuster up and down. To adjust, locate the slider / paddle with "↑↓" icons on the inside of the B-pillar (the pillar between the door and rear window; in some models, it's on the seat shoulder). Moving these sliders / paddles adjusts the seatbelt height. However, in actual use, occupants need to turn around and reach out to move the sliders / paddles while seated, making it difficult to exert force and causing inconvenience. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a height adjustment device for seat belts. The slider drives the mounting plate to move quickly and stably, causing the mounting plate to move the buckle, thereby adjusting the height of the buckle. This, in turn, causes the buckle to move the seat belt passing through it upward or downward, thus automatically and stably adjusting the height of the seat belt.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a height adjustment device for a seat belt, including a mounting base, an adjustment platform is provided on the upper side of the mounting base, guide grooves are provided on both inner walls of the adjustment platform, a slider is slidably arranged inside each guide groove, a mounting plate is provided between the opposite inner sides of the two sliders, a rotating seat is rotatably arranged on the mounting plate, and a buckle is provided on the rotating seat; the buckle is detachably installed on the rotating seat by bolts.

[0006] As a further improvement of this utility model, a driving mechanism is also provided between the mounting base and the adjusting table. The driving mechanism is used to adjust the position of the buckle. The driving mechanism includes adjusting screws that are symmetrically rotatably disposed inside the mounting base. Each slider has a threaded groove, and the adjusting screws are threadedly connected to the adjacent threaded grooves. Symmetrically distributed support plates are fixedly disposed between the mounting base and the adjusting table. Each support plate has a rotating shaft that is rotatably disposed on it. A bevel gear II is fixedly sleeved on the side of the outer arc surface of the rotating shaft away from the vertical center of the mounting base. A bevel gear I is fixedly sleeved on the outer arc surface of each adjusting screw. Each bevel gear I is fixed to the adjacent bevel gear II by a coupling.

[0007] As a further improvement of this utility model, a dual-axis motor is provided in the middle of the mounting base, and the output shafts of the dual-axis motor are fixed to the adjacent rotating shafts by couplings.

[0008] As a further improvement of this utility model, the outer side of the mounting base is provided with symmetrically distributed connecting plates, each of which has multiple connecting holes, and the bottom of each connecting hole is provided with a rubber ring.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the bolts are passed through the connecting holes on the connecting plate, and then the connecting plate is installed on the car by tightening the bolts with external tools. During installation, the rubber rings installed in the connecting holes effectively prevent damage to the connecting plate due to excessive tightening of the bolts.

[0011] Secondly, the dual-axis motor is controlled by an external control system, which causes the slider to move the mounting plate, which in turn moves the buckle, adjusting the height of the buckle. This, in turn, causes the buckle to move the safety belt passing through it up or down, thus adjusting the height of the safety belt.

[0012] Third, the output shafts of the dual-axis motors drive the rotating shafts connected to them to rotate, which in turn drives the adjusting screw connected to it to rotate, thereby causing the adjusting screws on both sides to rotate synchronously. By adjusting the thread relationship between the adjusting screw and the slider, the slider slides against the guide groove, thereby stabilizing the height of the buckle. Attached Figure Description

Detailed Implementation

[0019] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0020] like Figure 1 , 2 As shown, the device includes a mounting base 101. An adjustment platform 102 is provided on the upper side of the interior of the mounting base 101. Guide grooves 103 are provided on both inner walls of the adjustment platform 102. A slider 104 is slidably arranged inside each guide groove 103. A mounting plate 105 is provided between the opposite inner sides of two sliders 104. A rotating seat is rotatably arranged on the mounting plate 105. A buckle 106 is provided on the rotating seat. A driving mechanism is also provided between the mounting base 101 and the adjustment platform 102. The driving mechanism is used to adjust the position of the buckle 106.

[0021] like Figure 3 , 4 As shown, the driving mechanism includes an adjusting screw 201 symmetrically rotatably disposed inside the mounting base 101. Each slider 104 has a threaded groove, and the adjusting screw 201 is threadedly connected to the adjacent threaded groove. Symmetrically distributed support plates 205 are fixedly disposed between the mounting base 101 and the adjusting table 102. Each support plate 205 is rotatably disposed on a rotating shaft 203. A bevel gear 204 is fixedly sleeved on the side of the outer arc surface of the rotating shaft 203 away from the vertical center of the mounting base 101. A bevel gear 202 is fixedly sleeved on the outer arc surface of each adjusting screw 201. Each bevel gear 202 is fixed to the adjacent bevel gear 204 by a coupling. A dual-axis motor 206 is disposed in the middle of the mounting base 101. The output shaft of the dual-axis motor 206 is fixed to the adjacent rotating shaft 203 by a coupling.

[0022] like Figure 1 , 2 As shown, buckle 106 is detachably mounted on the rotating seat by bolts.

[0023] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the outer side of the mounting base 101 is provided with symmetrically distributed connecting plates 107, and each connecting plate 107 is provided with multiple connecting holes 108, and each connecting hole 108 is provided with a rubber ring at its inner bottom.

[0024] In use, the bolt is passed through the connecting hole 108 on the connecting plate 107, and then the connecting plate 107 is installed on the car by tightening the bolt with an external tool. During installation, the rubber ring set in the connecting hole 108 effectively prevents the connecting plate 107 from being damaged due to excessive tightening of the bolt. The seat belt of the car is passed through the buckle 106 set on the rotating seat.

[0025] Then, the dual-axis motor 206 is controlled by an external control system to run, which in turn drives the rotating shaft 203 connected to it to rotate, thereby driving the bevel gears 204 on both sides to rotate synchronously. The meshing relationship between the bevel gears 204 and the first bevel gear 202 drives the first bevel gears 202 on both sides to rotate synchronously, which in turn drives the adjusting screw 201 connected to it to rotate, thereby driving the adjusting screws 201 on both sides to rotate synchronously. The thread relationship between the adjusting screw 201 and the slider 104 causes the slider 104 to slide between the slider and the guide groove 103, which in turn causes the slider 104 to move the mounting plate 105, which in turn causes the mounting plate 105 to move the buckle 106, adjusting the height of the buckle 106. This causes the buckle 106 to move the safety belt passing through it up or down, thus adjusting the height of the safety belt.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
