Description

Technical Field

[0001] The invention belongs to the technical field of vehicle tire safety, and in particular relates to an armored airbag type tire bursting continuing wheel, a tire inner supporting material, and a vehicle with the continuing wheel. Background Art

[0002] Military vehicles fighting on the battlefield are most afraid of having their tires shot. Tires that are shot through or punctured by shrapnel will cause rapid deflation or even paralysis of the vehicle, putting both the driver and the vehicle in extreme danger. At present, the most practical explosion-proof tires in the prior art all adopt sidewall reinforcement technology, tire support, solid wheels and other solutions. The explosion-proof tire sidewall reinforcement technology mainly provides a reinforcement layer with high hardness and strength in the tire sidewall, and when the tire is deflated, the reinforced tire sidewall supports the tire to continue to travel a distance. The tire support is a rubber or metal bracket installed in the tire cavity, and the bracket supports the weight of the vehicle after the tire is deflated. The tire support is not only heavy and difficult to load and unload, but also the reduction of the wheel radius after the tire is blown makes the vehicle's handling suddenly worse, and the vehicle may still lose control. Although the solid wheel will not burst, its elasticity, adhesion, economic performance, cost price and other aspects are much worse than those of pneumatic tires.

[0003] The three existing explosion-proof tire solutions all have the defect of being unable to withstand multiple attacks of bullets. In order to solve the above technical problems, the present invention is hereby provided. Summary of the invention

[0004] In view of at least one of the above-mentioned technical problems, the object of the present invention is to provide a vehicle and its armored airbag type tire-bursting continuing wheel and tire inner support device.

[0005] The technical solution of the present invention is:

[0006] One of the purposes of the present invention is to provide an armored airbag tire-bursting wheel, the wheel comprising a rim and a tire mounted on the rim, a tire cavity being formed between the tire and the rim, the tire inner support device being mounted in the tire cavity, comprising:

[0007] The soft support part is an annular hollow body with a cavity inside, and can expand outward in an inflated state. The soft support part has a pre-inflated state when the outer tire is not damaged and an expanded state when the outer tire is damaged. In the pre-inflated state, the inner cavity of the soft support part is pre-inflated with gas of the same air pressure as the tire cavity of the outer tire;

[0008] The armor protection part is made of bulletproof material and is arranged in the tire cavity and distributed on the outer periphery of the soft support part, and its inner end is tightly fixed on the rim. The armor protection part has a first state in which the soft support part is contracted when the soft support part is in a pre-inflated state and a second state in which the soft support part is forced to expand when the soft support part is in an expanded state. In the first state, there is a gap between the outer end of the armor protection part and the inner wall of the outer tire. In the second state, the outer end of the armor protection part is pressed against the inner wall of the outer tire.

[0009] Preferably, the soft supporting portion is an air bag with an inflation nozzle.

[0010] Preferably, the armor protection part includes:

[0011] An inner fixing frame, which is suitable for being sleeved and fixed on the rim, and whose outer contour forms a first circle;

[0012] an outer guard plate, which is arranged on the radial outer periphery of the first circle and whose outer contour forms a second circle in the second state;

[0013] Two side guard plates that are opposite to each other and spaced apart in the annular area defined by the first circle and the second circle, the inner end of any side guard plate being movably connected to the inner fixing frame and the outer end being movably connected to the outer guard plate;

[0014] The inner fixing frame, outer guard plate and side guard plates are all made of bulletproof material;

[0015] In the first state, the two side guard plates are arranged at an angle to the radial direction of the ring; and

[0016] In the second state, the two side guard plates are consistent with the radial direction of the ring.

[0017] Preferably, either side guard plate is composed of a plurality of first sheets arranged at intervals along the circumferential direction of the annular area, the two ends of the length direction of any first sheet being connected to the inner fixing frame and the outer guard plate by hinges, and the length direction of any first sheet forming an angle with the radial direction of the annular ring in the first state and being consistent with the radial direction of the annular ring in the second state.

[0018] Preferably, the internal fixation frame is formed by connecting a plurality of second sheets connected by hinges; and / or

[0019] The outer guard plate is formed by connecting a plurality of third plates connected by hinges.

[0020] Preferably, the armor protection part also includes an elastic member arranged on the outer guard plate, at least one of the elastic members is connected between any two adjacent third sheets, or the elastic member is arranged between two adjacent third sheets at at least one position, and the elastic member applies a biasing force that causes all the third sheets to tend to move closer together so that the armor protection part is in the first state.

[0021] Preferably, the elastic member is a spring ring.

[0022] Preferably, a heat insulation layer is provided on a side of the inner fixing frame close to the rim.

[0023] Another object of the present invention is to provide an armored airbag type tire-bursting continuing wheel, comprising a rim and a tire mounted on the rim, a tire cavity being formed between the tire and the rim, and also comprising an in-tire support device of any of the above-mentioned armored airbag type tire-bursting continuing wheels arranged in the tire cavity.

[0024] Another object of the present invention is to provide a vehicle comprising the above-mentioned armored airbag type tire-bursting continuing wheel.

[0025] Compared with the prior art, the advantages of the present invention are:

[0026] The in-tire support device of the armored airbag type tire-bursting continuing wheel of the present invention is composed of two parts: a soft support part and an armored protection part. When there is no tire burst, there is a gap between the armored protection part and the inner wall of the outer tire, so that the support device will not affect the rolling and deformation of the outer tire. After the tire bursts, the pre-filled gas in the soft support part automatically expands the soft support part. When the soft support part expands, the outer wall squeezes the armored protection part, so that the armored protection part is forced to switch from a retracted state to an expanded state. The air pressure in the soft support part can reach 50%-80% of the normal air pressure, which is enough to support the weight of the vehicle and travel normally. The armored protection part can not only protect the soft support part from damage when there is no tire burst and after the tire burst, but also support the damaged outer tire when the tire bursts, avoiding serious deformation during rolling and affecting normal travel. With the wheel of the present invention, when the outer tire is penetrated by a bullet, the outer tire is damaged and a tire blows out. At this time, the gas in the soft supporting part automatically expands to reach 50%-80% of the normal air pressure, and at the same time, the armor protection part expands to form a support while surrounding the soft supporting part for protection, thereby supporting the weight of the vehicle and allowing the vehicle to travel normally. When the bullet penetrates the outer tire again, the armor protection part is made of bulletproof material, which can prevent the bullet from penetrating the soft supporting part, resulting in the tire being unable to support the weight of the vehicle and unable to travel normally, thereby solving the defect in the prior art that the tire that continues to run after a tire blows out cannot resist multiple attacks by bullets.

[0033] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0034] Example 1

[0035] See also Figures 1 to 4 The invention discloses an armored airbag type tire-bursting wheel inner tire support device. The wheel comprises a rim and a tire 1 mounted on the rim, a tire cavity is formed between the tire 1 and the rim, and the rim comprises Figure 1The left half rim 3 and the right half rim 4 are shown, and the left half rim 3 and the right half rim 4 are fixedly mounted on the wheel spoke plate 2 by bolts. The tire inner support device includes a soft support part 5 and an armor protection part. The soft support part 5 is an annular hollow cavity with a cavity inside, which can expand outward in an inflated state. The soft support part 5 has a pre-inflated state when the outer tire 1 is not damaged and an expanded state when the outer tire 1 is damaged. In the pre-inflated state, the inner cavity of the soft support part 5 is pre-inflated with gas with the same air pressure as the tire cavity of the outer tire 1. In the expanded state, the air pressure in the soft support part 5 can be controlled at 50%-80% of the normal air pressure, which is sufficient to support the weight of the vehicle and run normally. The armor protection part is made of bulletproof material (specific description and limitation are not made, and it is a bulletproof material known to those skilled in the art) and is arranged in the tire cavity and distributed on the periphery of the support part. The inner end of the armor protection part is tightly fixed on the rim, and the armor protection part has a first state in which the soft support part 5 is retracted when the soft support part 5 is in the pre-inflated state, and a second state in which the soft support part 5 is forced to expand with the soft support part 5 when the soft support part 5 is in the expanded state. In the first state, there is a gap between the outer end of the armor protection part and the inner wall of the outer tire 1, that is, the armor protection part does not contact the inner wall of the outer tire 1. In the second state, the outer end of the armor protection part presses against the inner wall of the outer tire 1, that is, the armor protection part is very close to or even in contact with the inner wall of the outer tire 1. The tire support device of the present invention is improved on the basis of the existing airbag type tire bursting wheel, and is composed of two parts: the soft support part 5 and the armor protection part. When there is no tire burst, there is a gap between the armor protection part and the inner wall of the outer tire 1, so that the support device will not affect the rolling and deformation of the outer tire 1. When a tire bursts, the pre-filled gas in the soft support portion 5 automatically expands the soft support portion 5. When the soft support portion 5 expands, the outer wall squeezes the armor protection portion, so that the armor protection portion is forced to switch from a contracted state to an expanded state. The air pressure in the soft support portion 5 can reach 60%-80% of the normal air pressure, which is enough to support the weight of the vehicle and drive normally. The armor protection portion can not only protect the soft support portion 5 from damage before and after a tire burst, but also support the damaged outer tire 1 in case of a tire burst, thereby preventing the outer tire from being severely deformed during rolling and affecting normal driving.

[0036] According to some preferred embodiments of the present invention, the soft support portion 5 is an airbag with an independent inflation nozzle, which is made of high-strength, high-elasticity, and high-temperature resistant material. The specific material is not described or limited, and is an existing conventional material known to technical personnel in this field and easily realized, such as semi-thermoplastic polyurethane elastic TPU.

[0037] According to some preferred embodiments of the present invention, Figures 1 to 4 As shown, the armor protection part includes an inner fixing frame 6, an outer guard plate 9 and a pair of side guard plates (such as Figure 1 and Figure 3As shown, a pair of side guard plates are the left guard plate 7 and the right guard plate 8 respectively). It should be noted that in the second state, the outer shape of the armor protection part is also a ring. The inner fixing frame 6 is sleeved and fixed on the rim, and its outer contour forms a first circle. The outer guard plate 9 is arranged on the radial outer periphery of the first circle and its outer contour forms a second circle. A pair of side guard plates are arranged oppositely and at intervals on both sides of the axial direction of the annular area of ​​the first circle and the second circle. The inner end of any side guard plate, that is, the left guard plate 7 and the right guard plate 8, is movably connected to the inner fixing frame 6 and the outer end is movably connected to the outer guard plate 9. The inner fixing frame 6, the outer guard plate 9, the left guard plate 7, and the right guard plate 8 are all made of bulletproof material (specific description and limitation are not made, and those skilled in the art know). In the first state, the two side guard plates are inclined at an angle to the radial direction of the ring enclosed by the first circle and the second circle. In the second state, the two side guard plates are consistent with the radial direction of the ring enclosed by the first circle and the second circle. That is to say, since the two ends of the side guard plate are movably connected to the inner fixing frame 6 and the outer guard plate 9, when the soft support part 5 is in the pre-filled state, the outer guard plate 9 is not a complete circle at this time. The side guard plate is not affected by the expansion tension of the outer guard plate 9 and is in a drooping and relaxed state under the action of its own gravity, that is, it is inclined at an angle to the radial direction of the ring. When the soft support part 5 is in the expanded state, the outer guard plate 9 is forced to expand outward so that its outer contour forms a complete second circle. During the expansion, radial tension is applied to the left guard plate 7 and the right guard plate 8, so that the left guard plate 7 and the right guard plate 8 are straightened, that is, consistent with the radial direction of the ring.

[0038] According to some preferred embodiments of the present invention, Figure 2 and Figure 4As shown, any side guard plate, i.e., the left guard plate 7 or the right guard plate 8, is composed of a plurality of first sheets arranged at intervals along the circumference of the annular region, and the two ends of the length direction of any first sheet are connected to the inner fixing frame 6 and the outer guard plate 9 by hinges (not shown), and the length direction of any first sheet forms an angle with the radial direction of the annular region in the first state and is consistent with the radial direction of the annular region in the second state. That is to say, the side guard plate is composed of a plurality of first sheets arranged at intervals along the annular region and is movably connected to the inner fixing frame 6 and the outer guard plate 9 by hinges, and has a simple structure and is easy to process, while also avoiding the formation of large interference resistance of the armor protection part during the folding and expansion process due to the excessive size of the side guard plate structure. Preferably, the inner fixing frame 6 is connected by a plurality of second sheets connected by hinges (not shown). The outer guard plate 9 is connected by a plurality of third sheets connected by hinges (not shown). Similarly, the sheets are connected together by hinges (not shown), which has a small interference resistance during folding and expansion, is easy to fold and expand, and is easy to process and assemble. It should be noted that for the multiple first sheets or multiple second sheets or multiple third sheets, the shapes of the sheets are the same, which is convenient for processing with the same set of processing molds, reducing development and production costs. The first sheet is a flat sheet, and the second sheet and the third sheet are arc-shaped sheet. As an alternative, the connection method between the first sheet and the inner fixing frame 6 and the outer guard plate 9 and the connection method between the multiple second sheets and the multiple third sheets can also be other mechanical connection methods known to those skilled in the art, which are not specifically described or limited. The multiple second sheets are made of hard plastic and elastic material, and are elastically clamped on the rim. The multiple third sheets are made of hard plastic and arranged in a fish scale shape. For hard plastic, no specific description or limitation is made, such as existing conventional plastics such as ABS, PS, PC, PET, etc., and elastic materials are not described or limited, such as existing conventional polyester elastomers, propylene elastomers, vinyl elastomers, fluorine / silicone elastomers, etc. Plastic materials are used, which are lower in cost than metal materials. As can be seen from the above, the armor protection part is made of bulletproof material. Therefore, it can be known that conventional bulletproof materials currently available on the market are added to the hard plastic during the processing process. The specific production and processing technology is not described and limited, and is not the innovation point of the present invention.

[0039] According to some preferred embodiments of the present invention, Figure 1 and Figure 3As shown, the armor protection part also includes an elastic member 10 arranged on the outer guard plate 9. At least one elastic member 10 is connected between any two adjacent third sheets or an elastic member 10 is arranged between two adjacent third sheets at at least one position. The elastic member 10 applies a biasing force that makes all the third sheets tend to be close together so that the armor protection part is in the first state. In this way, the outer guard plate 9 has a certain elasticity, and is pressed against the inner wall of the outer tire 1 when the tire bursts, and can produce a certain deformation along with the tread when the outer tire 1 rolls on the ground. The setting of the elastic member 10, first, puts the sheets of the outer guard plate 9 together and arranges them neatly to play a guiding role; second, when there is no tire burst, the sheets of the outer guard plate are gathered together by elasticity; third, it balances the centrifugal force of the outer guard plate 9 when the wheel rotates. Preferably, the elastic member 10 is an elastic ring.

[0040] According to some preferred embodiments of the present invention, a heat insulating layer (not shown) is provided on one side of the inner fixing frame 6 close to the rim, so as to block the radiant heat of the brake. It should be noted that the soft support part 5 is mounted on the inner fixing frame 6. Specifically, the inflation nozzle on the soft support part 5 is penetrated and fixed on the inner fixing frame 6. The inner fixing frame 6 is not only the installation base of the outer guard plate 9 and the side guard plate of the soft support part 5 and the armor protection part, but also can prevent the tire foot of the outer tire 1 from sliding inward under special circumstances.

[0041] Example 2

[0042] The embodiment of the present invention provides an armored airbag type tire bursting and continuing wheel, see Figures 1 to 4 , including a rim and a tire 1 mounted on the rim, a tire cavity is formed between the tire 1 and the rim, and the rim includes Figure 1 The left half rim 3 and the right half rim 4 are fixedly mounted on the wheel spoke plate 2 by bolts, and also include the tire inner support device of the armored airbag type tire bursting and continuing wheel of embodiment 1 arranged in the tire cavity. Since the tire inner support device in embodiment 1 is provided, it has at least the beneficial effects of the tire inner support device in the above embodiment, which will not be repeated here. Since the wheel of the present invention has the tire inner support device in embodiment 1, when the outer tire is shot through by a bullet, the outer tire is damaged and a tire burst occurs. At this time, the gas in the soft support part automatically expands to 50%-80% of the normal air pressure, and the armor protection part expands to form a support while surrounding the soft support part for protection, supporting the weight of the vehicle, so that the vehicle can run normally. When the bullet shoots through the outer tire again, since the armor protection part is made of bulletproof material, it can prevent the bullet from penetrating the soft support part, resulting in the tire being unable to support the weight of the vehicle and unable to run normally, solving the defect that the tire of the tire bursting and continuing tire in the prior art cannot resist multiple attacks of bullets.

Since the tire-bursting continuing wheel of embodiment 2 is provided, the vehicle at least has the beneficial effects of the tire-bursting continuing wheel of the above embodiment, which will not be described in detail here.

[0045] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
