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 adjustable width pad belt. Background Technology

[0002] The tire blowout emergency safety device is a new type of automotive safety device. Its main function is to enable the vehicle to drive safely and stably when a tire blows out, through its unique structure and materials, avoiding dangerous situations such as loss of control and rollover caused by the blowout. This device is mainly made of modified polymer materials and its width is generally fixed. It is a ring-shaped device installed inside the wheel. When a tire blows out, the tire blowout emergency safety device can fit tightly against the wheel rim, increasing friction and enabling the vehicle to achieve better handling, stability and safety.

[0003] However, current tire blowout emergency safety devices have some problems: when a car is in high-temperature conditions, the road temperature rises, and the tire material may expand due to the thermal expansion and contraction characteristics, and the tire diameter may increase. However, the width of the current tire blowout emergency safety device is fixed, which may create a gap between it and the tire, thereby reducing safety. At the same time, when a car is in low-temperature conditions, the tire material will shrink and the tire diameter will decrease. However, the width of the current safety device cannot be adjusted, which may make it too tight, putting additional pressure on the tire and even affecting vehicle driving. Therefore, a tire blowout emergency safety device with adjustable width is proposed. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a width-adjustable pad-type tire blowout emergency safety device, which solves the problem that the width of the existing pad-type tire blowout emergency safety device cannot be adjusted.

The first and second steel belts are connected as a whole by an adjusting component and are disposed on the outer wall of the telescopic pad. The two ends of the telescopic pad and the two ends of the first steel belt are connected into a ring by the same limiting component. The telescopic pad has a groove, and the tire pressure detection component is disposed within the groove on the telescopic pad. The adjusting component drives the second steel belt to slide and extend along the first steel belt, and the second steel belt drives the telescopic pad to extend and extend synchronously.

[0006] Preferably, the limiting component includes a first bolt and a lock nut, and both ends of the telescopic pad and both ends of the first steel strip are provided with screw holes, and the first bolt passes through the screw holes and is connected to the lock nut.

[0022] 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.

[0023] Please see Figure 1 - Figure 4 This embodiment provides a width-adjustable pad-type tire blowout emergency safety device, including a telescopic pad 1, a first steel belt 2, a second steel belt 3 slidably disposed within the first steel belt 2, a tire pressure detection component 4, and a limiting component 5. The first steel belt 2 and the second steel belt 3 are connected as one unit by an adjusting component 6 and are disposed on the outer wall of the telescopic pad 1. The two ends of the telescopic pad 1 and the two ends of the first steel belt 2 are connected into a loop by the same limiting component 5. The telescopic pad 1 is provided with a groove, and the tire pressure detection component 4 is disposed in the groove on the telescopic pad 1. The adjusting component 6 drives the second steel belt 3 to slide and extend along the first steel belt 2, and the second steel belt 3 drives the telescopic pad 1 to extend and extend synchronously. Here, the telescopic pad 1 is composed of the first pad and the second pad. The second pad is slidably disposed within the first pad, and the second pad and the first pad are connected by a first spring. The extension and retraction direction of the first spring is in the same straight line as the sliding direction of the second pad. This design not only ensures that the second pad extends and retracts along the first pad, but also allows the reaction force of the first spring to limit the extension and retraction of the second pad.

[0024] The first steel belt 2 is a steel belt fixed to the outer wall of the telescopic pad 1, used to support and fix the telescopic pad 1. The second steel belt 3 is slidably disposed within the first steel belt 2 and is connected to the first steel belt 2 through the adjusting component 6, used to drive the telescopic pad 1 to extend and retract. The tire pressure detection component 4 is a component installed in the groove of the telescopic pad 1, used to monitor the tire pressure. The limiting component 5 is used to connect the components at both ends of the telescopic pad 1 and the first steel belt 2 to ensure the stability of the structure. The adjusting component 6 drives the second steel belt 3 to slide and extend and retract along the first steel belt 2. This means that under high temperature conditions or low temperature conditions, the movement of the second steel belt 3 can be controlled by the adjusting component 6, thereby driving the telescopic pad 1 to extend and retract synchronously to adapt to changes in tire width. In addition, the inner wall of the telescopic pad 1 is provided with several flexible protrusions 7, which on the one hand can increase the friction between it and the wheel hub, making the tire blowout emergency safety device firm and reliable, and on the other hand can prevent excessive friction between the tire blowout emergency safety device and the wheel hub, thus preventing damage to the wheel hub.

[0025] Because the current tire blowout emergency safety device has a fixed width, there are some problems in its use. When a car is in high-temperature conditions, the road temperature rises, and the tire material may expand due to the thermal expansion and contraction properties, increasing the tire diameter. However, since the width of the tire blowout emergency safety device is fixed, a gap may be created between it and the tire, thus reducing safety. At the same time, when a car is in low-temperature conditions, the tire material shrinks, reducing the tire diameter. Since the width of the current safety device cannot be adjusted, it may be too tight, putting extra pressure on the tire and even affecting vehicle operation.

[0026] To solve the above problems, in this embodiment, the first steel belt 2 and the second steel belt 3 are connected as one unit by the adjusting component 6 and are set on the outer wall of the telescopic pad 1. The two ends of the telescopic pad 1 and the two ends of the first steel belt 2 are connected into a ring by the same limiting component 5. The telescopic pad 1 is provided with a groove, and the tire pressure detection component 4 is set in the groove on the telescopic pad 1. The adjusting component 6 drives the second steel belt 3 to slide and extend along the first steel belt 2, and the second steel belt 3 drives the telescopic pad 1 to extend and extend synchronously, so as to adapt to the width change of the tire and solve the problem that the width of the pad-type tire blowout emergency safety device cannot be adjusted.

[0027] To further improve the stability between the telescopic pad 1 and the wheel hub, and to ensure that vibrations of the vehicle wheel hub do not cause the telescopic pad 1 to loosen, in one embodiment, the limiting component 5 includes a first bolt 51 and a lock nut 52. Both ends of the telescopic pad 1 and both ends of the first steel strip 2 are provided with screw holes. The first bolt 51 passes through the screw holes and connects to the lock nut 52. By using the first bolt 51 and the lock nut 52 to connect the telescopic pad 1 and the wheel hub, loosening between the telescopic pad 1 and the wheel hub due to vibrations of the vehicle wheel hub can be effectively prevented. The special design of the lock nut 52 makes it difficult to loosen in a vibration environment, ensuring the stability of the connection. The screw holes at both ends of the telescopic pad 1 and the first steel strip 2 ensure that... The connection is secured by the first bolt 51, making the connection more robust and reliable, reducing the risk of connection failure due to vibration. The tire pressure monitoring assembly 4 includes a tire pressure monitoring fixing plate. The two ends of the tire pressure monitoring fixing plate are connected to the telescopic pad 1 by the second bolt. The tire pressure monitoring fixing plate is usually designed to be made of a strong and lightweight material, such as high-strength plastic or alloy. It needs to be fixed inside the tire and fit tightly against the tire sidewall. High-precision pressure sensors are integrated on the tire pressure monitoring fixing plate. These sensors can monitor tire pressure changes in real time. The two ends of the tire pressure monitoring fixing plate are connected to the pad 1 by the second bolt. This connection method must ensure a firm connection while allowing a certain degree of flexibility to adapt to tire deformation during driving.

[0028] To better adjust the width of the tire blowout emergency safety device and adapt it to safe vehicle use in extreme environments such as high or low temperatures, in one embodiment, the adjusting component 6 includes a slider 61 slidably disposed within a first steel strip 2 and a limiting rod 62 disposed on a second steel strip 3 within the first steel strip 2. The second steel strip 3 and the slider 61 are connected by a connecting rod. The first steel strip 2 also has several limiting grooves 21. The limiting rod 62 engages with any one of the limiting grooves 21. The end of the limiting rod 62 that engages with the limiting groove 21 has a hemispherical structure. This hemispherical design at one end of the limiting rod 62 helps to better adapt to the shape of the limiting groove 21, facilitating width adjustment. The adjustment also enhances the stability of the engagement and reduces the risk of dislocation due to vibration and other reasons. Several limiting grooves 21 cooperate with the limiting rod 62, allowing the overall width of the first steel strip 2 and the second steel strip 3 to be adjusted in multiple positions. Furthermore, the first pad of the telescopic pad 1 is provided with a groove that cooperates with the first steel strip 2, so that the end of the first steel strip 2 away from the second steel strip 3 is in contact with the side wall of the groove on the first pad, ensuring that the position of the first steel strip does not change when the position of the second steel strip 3 is adjusted. In addition, the limiting rod 62 is a spring telescopic rod, which is intended to facilitate operation when the limiting rod 62 moves from one limiting groove 21 to another limiting groove 21.

[0029] To ensure the tire blowout emergency safety device remains stable after its width is adjusted to a suitable position, preventing loosening due to vehicle vibration, in one embodiment, a groove 9 and several slots 8 are provided at the end of the first steel strip 2 away from the second steel strip 3. The groove 9 vertically penetrates the slots 8. The slider 61 is rotatably connected to the connecting rod. The slider 61 slides along the groove 9 or engages with any of the slots 8. The distance between two adjacent slots 8 is the same as the distance between two adjacent limiting grooves 21. The number of slots 8 is the same as the number of limiting grooves 21. In fact, the groove 9 is continuous, and the slots 8 are equivalent to grooves perpendicular to the groove 9, set at certain intervals on the groove 9. In the initial state, the slider 61 is located on the outer wall of the first steel strip 2 and is perpendicular to the first steel strip 2. The outer wall is fitted, and the slider 61 is perpendicular to the groove 9. The slider 61 is made of elastic material to avoid interference between the slider 61 and the first steel strip 2 and the telescopic pad 1. The width of the tire blowout emergency safety device needs to be selected according to the actual situation. When adjusting the width of the pad-type tire blowout emergency safety device, first rotate the slider 61 until it is parallel to the groove 9. At this time, pull the second steel strip 3 so that the second steel strip 3 can slide along the first steel strip 2. The second steel strip 3 drives the limiting rod 62 to engage with one of the limiting grooves 21. When the second steel strip 3 moves to the required position, the slider 61 moves to the position corresponding to the groove 8. At this time, rotating the middle part of the slider 61 by 90° will make the slider 61 engage perpendicularly with the groove 8. At this time, the width of the tire blowout emergency safety device is in a stable limiting state.

[0030] 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.
