DETAILED DESCRIPTION
[0018] In order to make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other. Example 1
[0019] like Figure 1As shown, a belt-type tire blowout emergency safety device comprises a belt body 1 and a connecting buckle 2. The belt body 1 is a flat, flexible cord made of a single material or a combination of multiple materials, or a combination of multiple strands of twisted yarn. Depending on the operating conditions, the cord can be made of fiber materials such as aramid (Kevlar), polyamide, polypropylene, nylon, and nylon. This embodiment uses aramid fiber as an example. Aramid is a new, high-tech synthetic fiber with excellent properties such as ultra-high strength, high modulus, high-temperature resistance, acid and alkali resistance, and light weight. Its strength is 5-6 times that of steel wire, its modulus is 2-3 times that of steel wire, and its toughness is twice that of steel wire, while weighing only about 1 / 5 of that of steel wire. It can withstand continuous use at temperatures between -196°C and 204°C for extended periods, fully meeting the operating temperature requirements of commercial vehicle wheels within the range of -41°C to 180°C. During production, aramid fibers are first twisted into silk threads, and then multiple strands of silk threads are braided into a flat soft rope. The entire roll of soft rope is then cut into sections according to the required length, and the two ends of each section of soft rope are closed by sewing or gluing to prevent the silk threads at the ends of the soft rope from loosening.
[0020] The two ends of the connecting buckle 2 and the two ends of the belt body 1 are connected in the following manner to form a closed loop, namely the tire blowout emergency safety device. During installation, the tire blowout emergency safety device is placed inside the vehicle wheel and encircles the wheel rim groove. The connection method is as follows: like Figure 2 、 Figure 3 and Figure 4 As shown, the bottom surface of the connecting buckle 2 faces the direction of the rim groove (inside), and the top surface of the connecting buckle 2 faces the direction of the tire (outside).
[0021] The connecting buckle 2 includes a left buckle 2.1 and a right buckle 2.2. The left end of the left buckle 2.1 is provided with a first hole 2.1.1 and a second hole 2.1.2. The right end of the right buckle 2.2 is provided with a third hole 2.2.1 and a fourth hole 2.2.2. When assembling or installing, the left end 1.1 (one end) of the belt body 1 first passes through the second hole 2.1.2 of the left buckle 2.1 from the inside to the outside, then passes through the first hole 2.1.1 from the inside to the outside, and then passes through the second hole 2.1.2 from the outside to the inside. , and then extends to the left end of the left buckle 2.1. The extension length is generally 20 to 60 mm, and can be longer or shorter if necessary; the right end 1.2 (the other end) of the belt body 1 first passes through the third hole 2.2.1 of the right buckle 2.2 from the inside to the outside, then passes through the fourth hole 2.2.2 from the inside to the outside, and then passes through the third hole 2.2.1 from the outside to the inside, and then extends to the right end of the right buckle 2.2. The extension length is generally 20 to 60 mm, and can be longer or shorter if necessary; A through hole 3 is provided on the left buckle 2.1 of the connecting buckle 2, and a nut 4 or a threaded hole 5 is provided on the right buckle 2.2. When the nut 4 is provided on the right buckle 2.2, the threaded hole 5 is changed to a round hole 3.1 which is the same as the through hole 3, and the nut 4 is stuck on the right side of the round hole 3.1. During installation, the screw 6 passes through the through hole 3, the threaded hole 5 or the round hole 3.1 in sequence, and is threadedly connected with the threaded hole 5 or the nut 4. A pin hole 6.1 is provided at one end of the screw 6, and an anti-loosening pin 7 is provided in the pin hole 6.1. The screw 6 can be replaced by a round head screw, such as a hexagon socket screw, or a square head or hexagon head screw; the anti-loosening pin 7 can be replaced by a cotter pin, a spring pin or a steel wire with a certain hardness. The anti-loosening pin 7 interferes with the connecting port 2 to prevent the screw 6 from rotating back and causing the tire blowout emergency safety device to loosen.
[0022] The left end 1.1 end of the belt body 1 extending to the left side buckle 2.1 is completed to sew (such as Figure 4 The right end 1.2 of the belt body 1, which has extended toward the right end of the right buckle 2.2, is secured to the belt body 1 by sewing to prevent the left end 1.1 of the belt body 1 from coming loose from the left buckle 2.1 and to increase tensile strength.
[0023] The width of the belt body 1 is smaller than the width of the wheel rim groove. Depending on the wheel size / specification, the belt body 1 can be a soft rope with a width of 10 to 120 mm and a thickness of 1 to 25 mm. The soft rope can be woven into an integral piece or can be made as Figure 3 As shown, multiple layers of soft ropes with a thickness of 1 to 6 mm are stacked and sewn together. Example 2
[0024] like Figure 5 As shown, a pad 8 is provided on the belt body 1. The pad 8 is made of a rubber block with a certain elasticity. The width of the pad 8 is smaller than the width of the rim groove, and the thickness of the pad 8 is smaller than the depth of the rim groove, which is usually 10 to 25 mm. The pad 8 is provided with a first hole 8.1 and a second hole 8.2 from the inside to the outside. After the belt body 1 passes through the first hole 8.1 from the inside to the outside, it passes through the second hole 8.2 from the outside to the inside. One pad 8 can be provided or multiple pads 8 can be provided. This embodiment takes the provision of one pad 8 as an example. The arc occupied by the pad 8 in the rim groove is 270° to 330°, and the two ends of the pad 8 are close to the left and right ends of the connecting buckle 2; if necessary, as Figure 6 As shown, at least one pair of holes 8.3, communicating with each other, are provided between the first hole 8.1 and the second hole 8.2. The belt body 1 passes through holes 8.3. To prevent axial misalignment between the belt body 1 and the spacer 8, at least one groove 8.4 is provided on the inner or outer circumference of the spacer 8. Groove 8.4 communicates with the through hole 8.1, through hole 8.2, or through hole 8.3 passing through the belt body 1. The corners of the connection positions are transitioned by circular arcs, and the belt body 1 passes through groove 8.4.
[0025] The other configurations of the second embodiment are the same as those of the first embodiment and will not be described again here. Example 3
[0026] like Figure 7 、 Figure 8 and Figure 9 As shown, this embodiment replaces the pad 8 with a hard rubber block and reduces its size. Multiple pads 8 are then installed on the belt body 1. Depending on the wheel specifications, the arc occupied by a single pad 8 in the rim groove ranges from 3° to 25°. Each pad 8 is evenly spaced and distributed on the belt body 1. Similarly, the pad 8 is provided with a first hole 8.1, a second hole 8.2, and a groove 8.4, through which the belt body 1 passes. To reduce weight, the pad 8 is also provided with weight-reducing holes or notches.
[0027] like Figure 8 As shown in the midsection (a), when the intersection of the angle formed by the centerline of the first hole 8.1 and the centerline of the second hole 8.2 is located on the outer circle of the cushion block 8, the larger the angle, the easier it is for the cushion block 8 to slip from the belt body 1 due to the rolling resistance of the wheel after a tire blowout, resulting in functional failure.
[0028] like Figure 8 As shown in the mid-section (b), when the intersection of the angle formed by the center line of the first hole 8.1 and the center line of the second hole 8.2 is located on the inner circle side of the pad 8, the larger the angle, the more difficult it is to slide from the belt body 1, and the connection between the pad 8 and the belt body 1 is more firmly. However, the material length required for the belt body 1 is longer, and the mold for producing the pad 8 needs to add a slider at the position of the corresponding hole. The larger the angle, the larger the slider stroke and the greater the mold cost.
[0029] like Figure 8 As shown in the midsection (c), when the angle formed by the center line of the first hole 8.1 and the center line of the second hole 8.2 is 0°, that is, parallel, the connection between the pad 8 and the belt body 1 is moderately firm, the mold of the pad 8 does not require a slider, and the cost is lowest.
[0030] Based on the above, the angle between the intersection of the center line of the first hole 8.1 and the center line of the second hole 8.2 is located on the inner circle of the pad 8. The angle used on large vehicles (such as 22.5 inches) is 45° to 110°, and the angle used on passenger cars and light trucks is 0° to 70°.
[0031] In order to increase the connection strength between the pad 8 and the belt body 1, at least one screw or screw can be set on the pad 8, and the screw or screw passes through the belt body 1 and is fixed to the pad 8. The belt body 1 can also be placed in the production mold of the pad 8 to be molded together.
[0032] If necessary, a protective cover 9 and / or a protective pad 10 are provided on the tire blowout emergency safety device to prevent the tire blowout emergency safety device from being worn out when in contact with the wheel rim during use, thereby affecting the service life.
[0033] The other configurations of the third embodiment are the same as those of the first embodiment and will not be described again here. Example 4
[0034] like Figure 10 and Figure 11 As shown, when the number of pads 8 on the belt body 1 is even, a counterweight 11 is provided at a position opposite the connecting buckle 2 on the closed loop (in the middle of the belt body 1). A first hole 11.1 and a second hole 11.2 are radially provided at one end of the counterweight 11, and a third hole 11.3 is circumferentially provided at the other end of the counterweight 11. The belt 1 passes from the inside out through the first hole 11.1 at one end of the counterweight 11, then from the outside in through the second hole 11.2, and finally through the third hole 11.3 toward the end of the counterweight 11. A sensor mounting hole 11.4 and / or mounting slot 11.5 are provided between the second hole 11.2 and the third hole 11.3. The sensor may be a TPMS sensor with functions for detecting tire pressure, temperature, etc., or an anti-loosening sensor with a function for detecting the loosening of a tire blowout emergency safety device.
[0035] If necessary, a protective cover 9 and / or a protective pad 10 are provided on the tire blowout emergency safety device to prevent the tire blowout emergency safety device from being worn out when in contact with the wheel rim during use, thereby affecting the service life.
[0036] The other configurations of the fourth embodiment are the same as those of the first embodiment and will not be described again here.
[0037] In summary, the present invention effectively solves the problem of abnormal wheel dynamic balance caused by displacement of the tire blowout emergency safety device during normal vehicle driving. In particular, it achieves lightweighting, with a weight reduction of 60% to 80% compared with other products on the market, reducing automobile carbon emissions. It can be widely used in passenger cars, buses, and commercial vehicles.
