[0002] Car seat belts are safety devices that restrain passengers in the event of a collision and prevent passengers from having a secondary collision with the steering wheel and dashboard, or from being thrown out of the car and causing death or injury. Car seat belts are recognized as the cheapest and most effective safety device, and many countries require seat belts to be mandatory in vehicle equipment.

[0003] There are four types of car seat belts based on the fixing method: two-point, three-point, four-point, and five-point. Among them, the two-point seat belt is a seat belt with only two fixing points to the car body or seat; it is commonly found on passenger seats in buses.

[0004] The common two-point seat belt can only protect the occupants from a secondary collision when encountering a collision, and the inertia generated by the collision is generally large. Therefore, during the collision, the two-point seat belt does not have a buffering ability and often causes strangulation injuries to the occupants. Utility Model Content

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] See also Figure 1 to Figure 6 As an embodiment of the utility model, the plug-in new automobile safety belt comprises a main safety belt 1 and a connector 2 installed on the main safety belt 1; and also comprises a secondary safety belt 5, and a buffer 4 is connected to the secondary safety belt 5;

[0032] The buffer member 4 is provided with a buffer assembly, and the buffer assembly is connected to a connecting sleeve 3. When the secondary safety belt 5 is subjected to tension, the buffer assembly can drive the buffer member 4 to slide on the connecting sleeve 3 to offset the tension applied to the secondary safety belt 5.

[0033] A limiting assembly is provided between the connecting sleeve 3 and the connecting member 2, and the connecting member 2 can be stably connected to the connecting sleeve 3 through the limiting assembly;

[0034] The connector 2 is also provided with a disconnection assembly, which can disconnect the limiting effect of the limiting assembly on the connector 2 and the connecting sleeve 3 .

[0035] In this embodiment, when it is necessary to wear a seat belt, by inserting the connector 2 into the connecting sleeve 3, under the action of the limiting assembly, the connector 2 will be stably connected to the connecting sleeve 3, so that the main seat belt 1 and the connecting sleeve 3 are stably connected, so that the main seat belt 1 and the auxiliary seat belt 5 are connected, so that the seat belt can firmly fix the passenger on the seat, so as to reduce the risk of injury to the passenger during the ride.

[0036] When the car brakes, the passengers will continue to move forward due to inertia, which will exert a pulling force on the auxiliary safety belt 5. This pulling force will cause the buffer 4 to slide in the connecting sleeve 3, and the resistance of the buffer 4 sliding in the connecting sleeve 3 will be gradually increased by the buffer assembly to offset the pulling force of the auxiliary safety belt 5, so as to reduce the damage to the passengers caused by the seat belt under the action of inertia.

[0037] The restriction of the limiting component on the connector 2 and the connecting sleeve 3 can be released by disconnecting the component, so that the connector 2 can be taken out of the connecting sleeve 3 to release the restriction of the seat belt on the passengers and facilitate the passengers to leave their seats.

[0038] As a further solution of the utility model, the limit assembly includes a connection plug 201 installed on the connection member 2, and the connection plug 201 can be slidably matched with the connection sleeve 3; a protrusion 202 is installed at one end of the connection plug 201 away from the connection member 2;

[0039] The limiting assembly further comprises a clearance groove 301 provided on the connecting sleeve 3 , a clearance spring 302 is installed in the clearance groove 301 , and a wedge block 303 connected to the clearance spring 302 is slidably installed in the clearance groove 301 .

[0040] In this embodiment, the side of the protrusion 202 away from the connecting member 2 has a characteristic of being inclined toward the connecting member 2, and the side close to the connecting member 2 has a flat surface characteristic perpendicular to the connecting member 2; the two sides of the wedge block 303 parallel to the connecting member 2 are set as planes, and the planes are connected with an inclined inward wedge surface with an inclined inward characteristic.

[0041] When the connecting plug 201 is inserted into the connecting sleeve 3, the wedge surface of the wedge block 303 close to the connecting member 2 will cooperate with the inclined surface of the protrusion 202. At this time, the kinetic energy of the connecting member 2 sliding into the connecting sleeve 3 will cause the wedge block 303 to slide inward in the clearance groove 301, and the clearance spring 302 will be compressed. When the protrusion 202 passes over the wedge block 303, the wedge block 303 is separated from the protrusion 202, and under the elastic force of the clearance spring 302, the wedge block 303 will slide outward in the clearance groove 301 until the elastic force disappears. At this time, the plane of the wedge block 303 will cooperate with the flat surface of the protrusion 202, thereby limiting the wedge block 303 from passing over the protrusion 202 in the reverse direction. The limiting assembly ensures that the connector 2 is stably connected to the connecting sleeve 3, and the connector 2 will not easily detach from the connecting sleeve 3, so that the main safety belt 1 is connected to the connecting sleeve 3, and thus the main safety belt 1 and the auxiliary safety belt 5 are stably connected, so as to reduce the risk of injury to people during riding.

[0042] As a further solution of the utility model, a sliding sleeve 208 is slidably installed on the connecting plug 201, a slot 209 is opened on the sliding sleeve 208, and a connecting spring 207 is installed in the slot 209; a sliding column 206 connected to the connecting piece 2 and the connecting spring 207 is slidably embedded in the slot 209.

[0043] In this embodiment, during the process of inserting the connection plug 201 into the connection sleeve 3, the sliding sleeve 208 will contact the connection sleeve 3; as the connection plug 201 continues to enter the connection sleeve 3, the connection sleeve 3 will squeeze the sliding sleeve 208, so that the sliding column 206 slides in the notch 209, thereby making the sliding sleeve 208 slide on the connection plug 201 toward the connection member 2. In this process, the connection spring 207 is continuously compressed, and its elastic force also increases. When the wedge block 303 passes over the protrusion 202, the elastic force of the connection spring 207 will continuously act on the sliding sleeve 208, so that the sliding sleeve 208 and the connection sleeve 3 are tightly fitted, so that the protrusion 202 and the wedge block 303 are tightly fitted, so that the connection member 2 and the connection sleeve 3 are stably connected without shaking, thereby improving the stability of the limit assembly.

[0044] As a further solution of the present invention, the disconnection assembly includes a slide groove 203 provided on the connection plug 201 , and a slider 204 is slidably engaged in the slide groove 203 ; a stopper 205 is also installed on the connection plug 201 .

[0045] In this embodiment, the slider 204 is triangular in shape.

[0046] When the safety belt needs to be unfastened, the connecting plug 201 is further inserted into the connecting sleeve 3, and the wedge block 303 drives the slider 204 to slide toward the stopper 205 in the slide groove 203. When the slider 204 slides to the end of the stroke, the slider 204 makes the wedge block 303 give way so that the slider 204 passes over the wedge block 303.

[0047] After the slider 204 passes over the wedge 303, the stopper 205 will contact the wedge 303, thereby limiting the connection plug 201 from being further inserted into the connection sleeve 3. After that, when the connection plug 201 is quickly pulled out, the wedge 303 will drive the slider 204 to slide toward the protrusion 202; when the slider 204 contacts the protrusion 202, the slider 204 will make the wedge 303 give way so that the wedge 303 passes over the slider 204, and because it is a quick pull, the inclined part of the wedge 303 after passing over the slider 204 will cooperate with the flat surface of the protrusion 202, so that the wedge 303 continues to give way so that the wedge 303 can pass over the protrusion 202, so as to separate the connection plug 201 from the connection sleeve 3. This releases the seat belt from limiting the position of the passengers, making it convenient for the passengers to leave the seats.

[0048] Moreover, the disconnection process is realized by inserting first and then quickly pulling out. Therefore, when wearing the safety belt, even if the insertion is too deep, the connector 2 will not be separated from the connecting sleeve 3, which ensures the stability of the connection and the convenience of the disconnection operation; at the same time, it can effectively prevent the safety belt from being detached, avoiding accidents for passengers during driving.

[0049] As a further solution of the utility model, the buffer assembly includes a buffer connecting plate 403 installed on the buffer member 4, and the buffer connecting plate 403 is slidably engaged with the connecting sleeve 3; a baffle 401 is installed at one end of the buffer connecting plate 403 away from the buffer member 4, and a buffer spring 402 connected to the connecting sleeve 3 is installed on the baffle 401.

[0050] In this embodiment, when the car changes from the driving state to the parking state, the passengers will tend to continue to move forward under the action of inertia, thereby applying tension to the auxiliary safety belt 5. Under the action of tension, the buffer connecting plate 403 will slide outward in the connecting sleeve 3, thereby driving the baffle 401 to compress the buffer spring 402. During this process, the elastic force of the buffer spring 402 will gradually increase, and the elastic force will continuously offset the tension on the auxiliary safety belt 5. When the car stops suddenly, the buffer component can effectively offset the tension generated by the seat belt under the action of inertia, thereby reducing the probability of the seat belt strangling the passengers.

[0051] As a further solution of the utility model, a plurality of groups of anti-skid grooves are provided on the outer surface of the connecting sleeve 3 , and the plurality of groups of anti-skid grooves can increase the friction coefficient of the outer surface of the connecting sleeve 3 .

[0052] In this embodiment, a plurality of groups of anti-skid grooves are provided to increase the friction coefficient of the outer surface of the connecting sleeve 3 so as to prevent the connecting sleeve 3 from slipping during use.

[0053] As a further solution of the present invention, a connecting column is installed on the main safety belt 1, and the main safety belt 1 can be connected to the seat through the connecting column.

[0054] In this embodiment, the main safety belt 1 is connected to the seat via a connecting column, thereby enhancing the restraint of the safety belt on the passenger when in use, thereby reducing the probability of the passenger being injured.

[0055] The above embodiments are exemplary rather than restrictive, so without departing from the spirit or basic features of the present invention, the technical solutions of the present invention that can be implemented in other specific forms are all included in the present invention.
