Description

Technical Field

[0001] This utility model belongs to the field of tire blowout emergency technology, specifically relating to a tire blowout emergency safety device with a pad belt. Background Technology

[0002] A tire blowout emergency safety device is a ring-shaped device installed inside the wheel to improve the safety of a vehicle in the event of a tire blowout. Currently, commercially available tire blowout emergency safety devices mainly consist of a tire strip and a steel strip. The tire strip and steel strip are installed in a ring shape on the inside of the wheel, and the ring connection between the tire strip and the steel strip is fixed with the same bolt and nut. This allows the tire strip and steel strip to tightly fill the groove on the wheel rim. In the event of a tire blowout, this device can quickly take effect, making the wheel rim and the tire belly tightly connected, thereby significantly increasing friction and ensuring the vehicle's handling, stability, and overall safety after a tire blowout.

[0003] However, current tire blowout emergency safety devices with shim belts still have some problems in use: during vehicle operation, the friction between the tire and the ground generates heat, causing the temperature of the bolt connection to change. This process of thermal expansion and contraction may cause the tightness of the bolt connection to change, leading to loosening. In addition, the vehicle will continuously vibrate during operation, and the bolt connection is also prone to loosening under the influence of this long-term vibration. To address these issues, a tire blowout emergency safety device with shim belts is proposed. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a tire blowout emergency safety device with a pad strip, which solves the problem that the process of thermal expansion and contraction may cause changes in the tightness of the bolt connection between the pad strip and the steel strip, resulting in loosening.

[0005] The purpose of this utility model can be achieved through the following technical solution: a pad-type tire blowout emergency safety device, including a pad, a steel strip wrapped around the pad, and a tire pressure detection component set on the pad. The two ends of the pad form a ring structure, and the two ends of the pad are connected by the same wedge-shaped self-locking component.

[0006] Preferably, the padding strip is provided with a slot, and the steel strip is disposed in the slot.

[0007] Preferably, the wedge-shaped self-locking assembly includes a trapezoidal part, a limiting part disposed on the bottom surface of the trapezoidal part, and a rotating part. The rotating part is connected to the waist of the trapezoidal part by a spring. The limiting part is in contact with one end of the pad. One end of the rotating part is hinged to the top surface of the trapezoidal part. The other end of the rotating part is self-locking with the other end of the pad. Both ends of the pad are provided with through holes that cooperate with the trapezoidal part. The limiting part drives the trapezoidal part to move along the through holes. The rebound force of the spring drives the rotating part to be in contact with the other end of the pad, so that the limiting part, the trapezoidal part, the rotating part, and the two ends of the pad are self-locking as a whole.

[0008] Preferably, a first groove is provided on the waist of the trapezoidal part, and the two ends of the spring are respectively connected to the bottom of the first groove and the rotating part.

[0009] Preferably, the rotating part is a rotating rod, and the length of the first groove is the same as the length of the rotating rod.

[0010] Preferably, one end of the rotating rod is hinged to the top surface of the trapezoidal part via a rotating shaft, the other end of the rotating rod has an arc-shaped structure, the other end of the pad is provided with a sliding groove, and the side wall of the sliding groove away from the trapezoidal part is provided with a second groove. The spring drives the other end of the rotating rod to slide along the sliding groove until the arc-shaped structure of the rotating rod engages with the second groove.

[0011] Preferably, the trapezoidal portion is an isosceles trapezoidal protrusion.

[0012] The beneficial effects of this utility model are as follows:

[0013] By incorporating a trapezoidal section, a limiting section, and a rotating section, when the pad is subjected to external force, the limiting section engages with one end of the pad, driving the trapezoidal section to move along the through-hole on the pad. As the trapezoidal section moves, the spring is compressed, accumulating energy. When the limiting section reaches a predetermined position, the spring's rebound force drives the rotating section to engage with the other end of the pad. At this point, the rotating section, the limiting section, and the trapezoidal section form a self-locking unit. This self-locking structure ensures that the pad will not detach when subjected to tension, and also allows for easy unlocking and relocking. This new limiting method solves the problem in existing technologies where thermal expansion and contraction can cause changes in the tightness of the bolt connection between the pad and the steel strip, leading to loosening.

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Please see Figure 1 - Figure 4 This embodiment provides a tire blowout emergency safety device with a pad belt 1, including a pad belt 1, a steel strip 2 wrapped around the pad belt 1, and a tire pressure detection component 3 set on the pad belt 1. The two ends of the pad belt 1 form a ring structure, and the two ends of the pad belt 1 are connected by the same wedge-shaped self-locking component 4. The pad belt 1 is a flexible pad belt 1. It should be noted that since the tire blowout emergency safety device with a pad belt 1 is usually pre-fixed to the wheel hub, during the vehicle manufacturing or maintenance process, this safety device is installed inside the wheel and fits tightly in the groove of the wheel hub. When the vehicle is driving normally, this device is already in a standby state. In the event of a tire blowout, the pre-installed pad belt 1 will immediately play its role. Since the device is fixed to the wheel hub, when the tire loses pressure, the pad belt 1 can prevent the tire from detaching from the wheel hub and maintain a tight fit between the tire and the wheel hub. The design of the wedge-shaped self-locking component 4 here makes the two ends of the pad belt 1 automatically lock when subjected to tension, forming a stable ring structure to prevent the pad belt 1 from loosening.

[0023] In addition, the pad 1 is provided with a slot, and the steel strip 2 is placed in the slot. The wedge-shaped self-locking assembly 4 includes a trapezoidal part 41, a limiting part 42 and a rotating part 43 provided on the bottom surface of the trapezoidal part 41. The rotating part 43 is connected to the waist of the trapezoidal part 41 by a spring 44. The limiting part 42 is attached to one end of the pad 1, one end of the rotating part 43 is hinged to the top surface of the trapezoidal part 41, and the other end of the rotating part 43 is self-locked to the other end of the pad 1. Both ends of the pad 1 are provided with through holes that cooperate with the trapezoidal part 41. The limiting part 42 drives the trapezoidal part 41 to move along the through holes, and the rebound force of the spring 44 drives the rotating part 43 to be attached to the other end of the pad 1, so that the limiting part 42, the trapezoidal part 41, the rotating part 43 and the two ends of the pad 1 are self-locked as a whole; the limiting part 42 is The limiting block and pad 1 are the basic parts of the assembly, usually made of materials with certain elasticity and wear resistance, such as rubber or nylon. The pad 1 is provided with slots, which are used to fix and guide the movement of the steel strip 2. Both ends of the pad 1 are provided with through holes that cooperate with the trapezoidal part 41. These through holes allow the trapezoidal part 41 to move along the pad 1 and ensure the self-locking function of the assembly. The trapezoidal part 41 is the main part of the assembly. Its shape is trapezoidal and it is used to cooperate with the through holes on the pad 1. The limiting part 42 is provided on the bottom surface of the trapezoidal part 41. Its main function is to limit the range of movement of the trapezoidal part 41. The spring 44 is connected to the waist of the rotating part 43 and the trapezoidal part 41. Its main function is to provide a rebound force when the rotating part 43 is in contact with the pad 1 to help the assembly self-lock.

[0024] During vehicle operation, the friction between the tires and the ground generates heat, causing temperature changes at the bolt connections. This thermal expansion and contraction can alter the tightness of the bolt connections, potentially leading to loosening. Furthermore, the continuous vibrations generated during vehicle operation can also cause bolt connections to loosen over time. To address this issue, this embodiment incorporates a trapezoidal portion 41, a limiting portion 42, and a rotating portion 43. When the pad 1 is subjected to external force, the limiting portion 42 engages with one end of the pad 1, driving the trapezoidal portion 41 to move along the through-hole on the pad 1. As the trapezoidal part 41 moves, the spring 44 is compressed and accumulates energy. When the limiting part 42 reaches the predetermined position, the rebound force of the spring 44 will drive the rotating part 43 to fit against the other end of the pad 1. At this time, the rotating part 43, the limiting part 42 and the trapezoidal part 41 form a self-locking whole. This self-locking structure can ensure that the pad 1 will not fall off when subjected to tension, and can also be easily unlocked and relocked. By adopting a new limiting method, the problem that the tightness of the bolt connection between the pad 1 and the steel strip 2 may change due to the thermal expansion and contraction process in the prior art, resulting in loosening, is solved.

[0025] To ensure that the rotating part 43 can be better locked with the other end of the pad 1 when the trapezoidal part 41 moves, in one embodiment, a first groove 45 is provided on the waist of the trapezoidal part 41. The two ends of the spring 44 are respectively connected to the bottom of the first groove 45 and the rotating part 43. The rotating part 43 is a rotating rod. In order to ensure better movement of the rotating rod and avoid the first groove 45 being too long and affecting stability, the length of the first groove 45 is the same as the length of the rotating rod. In addition, the design of the first groove 45 can ensure that the two ends of the spring 44 are stably fixed in the predetermined position, reducing the structural instability caused by the spring 44 loosening or shifting. Moreover, the two ends of the spring 44 are respectively connected to the bottom of the groove and the rotating rod, which helps to provide a uniform force when the rotating rod moves. In addition, the design of the groove provides a certain protection for the spring 44, preventing the spring 44 from being impacted or damaged during movement. And when the rotating rod is bounced up by the spring 44, the limiting block is just in contact with one end of the pad 1.

[0026] To further ensure that the limiting block cannot move and remains locked after the two ends of the pad 1 are connected, and that the rotating rod is also locked to the other end of the pad 1, and to maintain this state more stably, in one embodiment, one end of the rotating rod is hinged to the top surface of the trapezoidal part 41 by a pivot, and the other end of the rotating rod has an arc-shaped structure. The other end of the pad 1 is provided with a groove, and a second groove 5 is provided on the side wall of the groove away from the trapezoidal part 41. The spring 44 drives the other end of the rotating rod to slide along the groove until the arc-shaped structure of the rotating rod engages with the second groove 5. The trapezoidal part 41 is an isosceles trapezoidal protrusion, which can provide good support and stability, and help maintain the balance and firmness of the entire structure. The edge of the structure of the second groove 5 is an arc-shaped structure. This design can not only make the arc-shaped structure of the rotating rod engage with the second groove 5, but also make disassembly convenient.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
