Technical Field

[0001] The utility model belongs to the technical field of vehicles and relates to a vehicle component, in particular to a safety belt guide ring. Background Art

[0002] The seat belt guide ring is one of the important components of the vehicle seat belt assembly. The seat belt guide ring is located next to the headrest of the seat and is installed on the vehicle side pillar by bolts or rivets. The seat belt guide rings currently on the market generally adopt a symmetrical structure, and the shading parts on the left and right sides have the same width. The shading part is mainly used to block the gap / gap on one side. In actual use, when the seat belt is pulled, the seat belt guide ring will rotate at a certain angle. When the shading part on one side rotates to block the required gap / gap, the shading part of the same width on the other side will increase the probability of collision due to its larger width, affecting the user experience.

[0003] In order to overcome the shortcomings of the existing technology, people have proposed various solutions through continuous exploration. For example, a Chinese patent discloses a seat belt guide ring [application number: 201922184560.8], which includes: a guide ring body, a baffle, a limit block and a hole accessory. A fixing hole is provided at the upper part of the guide ring body, and a fixing bolt passes through the fixing hole to fix the guide ring body to the vehicle body. A guide hole is provided at the lower part of the guide ring body, and the seat belt webbing passes through the guide hole. However, this solution still adopts a symmetrical structure. In actual use, there is still a greater probability of collision between the user and the side away from the light shielding, which has the defect of poor user experience. Summary of the invention

[0004] The purpose of the utility model is to provide a safety belt guide ring in view of the above problems. The technical problem to be solved by the utility model is how to reduce the probability of collision with the user and improve the user experience under the premise of ensuring light shielding.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A seat belt guide ring comprises a metal frame and a plastic part, wherein the metal frame is provided with a middle strip-shaped through groove and a lower hole-shaped through groove, the metal frame is provided with a middle support body which is integrally formed with the metal frame and is located between the middle strip-shaped through groove and the lower hole-shaped through groove, the plastic part comprises an outer frame, a middle frame plate and an outer shading plate, the middle frame plate is provided with a connecting circular hole which is connected with the lower hole-shaped through groove, a seat belt abutment portion is provided on the top of the middle frame plate, a seat belt guiding channel is formed between the seat belt abutment portion and the metal frame, the back of the middle frame plate is provided with two limiting protrusions extending backwards, the outer shading plate is provided with a long shading side edge and a short shading side edge on both sides respectively, and the width of the long shading side edge is greater than the width of the short shading side edge.

[0007] In the above-mentioned safety belt guide ring, the long light-shielding side is arc-shaped along the outer side surface, and the short light-shielding side is concave inwardly along the outer side surface.

[0008] In the above-mentioned safety belt guide ring, the two limiting protrusions are respectively located on both sides of the connecting circular hole.

[0009] In the above-mentioned safety belt guide ring, a limiting groove is provided in the limiting protrusion.

[0010] In the above-mentioned safety belt guide ring, the back of the connecting circular hole is provided with a shaft sleeve, and the outer wall of the shaft sleeve is provided with a plurality of reinforcing ribs symmetrically along the center line of the shaft sleeve.

[0011] In the above-mentioned safety belt guide ring, installation side grooves are provided on both sides of the shaft sleeve, and the installation side grooves are staggered with the reinforcing ribs.

[0012] In the above-mentioned safety belt guide ring, two alignment side grooves and one middle alignment groove are provided on the back of the safety belt abutment portion, and the middle alignment groove is located between two adjacent alignment side grooves.

[0013] In the above-mentioned safety belt guide ring, a weight-reducing chamber is provided at the back of the outer frame, and a plurality of mutually parallel reinforcing vertical plates are provided in the weight-reducing chamber.

[0014] In the above-mentioned safety belt guide ring, the reinforcing vertical plate is integrally formed with the outer frame.

[0015] In the above-mentioned safety belt guide ring, the bottom of the back side of the outer frame has a central buckle block, and the central buckle block is located at the center line of the outer frame.

[0016] Compared with the existing technology, the advantages of the utility model are:

[0017] 1. During use, the utility model places the ring body composed of the metal frame and the plastic part at the doorpost of the car, and the safety belt passes through the safety belt guide channel formed between the safety belt abutting part and the metal frame. The safety belt abutting part can conveniently abut the upper edge of the safety belt to limit it, and the lower edge of the safety belt contacts and slides with the arc surface of the metal frame, and the arc surface can smoothly pull the safety belt. The metal frame is made of aluminum or iron, which has good wear resistance, avoids wear marks caused by long-term use, and improves the service life. The circular hole composed of the lower hole-shaped through groove and the connecting circular hole can be used to fix the connecting shaft body, and the two limiting protrusions can limit the rotation angle of the ring body relative to the shaft body. The asymmetric structure is adopted. When the safety belt is pulled out to drive the ring body to rotate, the long light-shielding side edge will block the gap between the doorpost and the interior of the car. By reducing the width of one side of the short light-shielding side edge, the effect of reducing the area can be achieved, which can reduce the probability of collision with the user, and the overall structure is compact and reasonable.
