Description

Technical Field

[0001] This utility model relates to the field of automotive auxiliary equipment technology, and in particular to a parking wedge with high friction. Background Technology

[0002] With the continuous growth of car ownership, the demand for safe parking of vehicles on slopes, in temporary parking areas, or in special terrains (such as construction sites and airport temporary parking areas) is becoming increasingly prominent. Traditional parking wedges (also known as wheel stops) are widely used in various parking scenarios as a key tool to prevent vehicles from accidentally sliding. However, existing parking wedges generally suffer from limited functionality and adaptability: on the one hand, most products are made of a single material (such as plastic or rubber), and their surface friction structure design is simple (such as a smooth surface or a few grooves), resulting in limited friction with the tires and the ground, making them prone to anti-slip failure on steep slopes or slippery surfaces; on the other hand, the bottom of traditional parking wedges is usually in direct contact with the ground, lacking specific optimization designs for uneven or hard surfaces, which can easily reduce stability due to localized pressure concentration or sliding displacement; in addition, some products do not consider impact protection mechanisms when vehicles run over them, which can easily lead to structural deformation or accelerated wear after long-term use, shortening their service life.

[0003] Chinese patent discloses a parking wedge (publication number: CN 212267432 U) comprising a support body having a bottom, an arc portion, and an inclined portion. Its characteristic is that it includes an anti-slip module detachably connected to the bottom of the support body. The bottom of the support body has a recessed cavity for installing the anti-slip module, and three limiting ports arranged in a "triangular" shape and communicating with the recessed cavity are respectively provided on the two side walls of the support body. However, this parking wedge has a simple surface friction structure design, lacks targeted optimization of the bottom, and lacks an impact buffer mechanism, resulting in insufficient anti-slip performance, poor stability, and susceptibility to impact damage. It is difficult to meet the high safety requirements of complex parking environments. Therefore, a parking wedge with high friction is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing parking wedges, which suffer from insufficient anti-slip performance, poor stability, susceptibility to impact damage, and difficulty in meeting the high safety requirements of complex parking environments due to their single material, simple surface friction structure design, lack of targeted optimization at the bottom, and lack of impact buffering mechanisms. Therefore, this invention proposes a parking wedge with high friction.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A parking wedge with high friction force, comprising a wedge body, characterized in that: the upper surface of the wedge body is provided with a textured structure to increase friction force; the wedge body is made of polyethylene; the bottom of the wedge body is provided with a friction iron plate structure; and reinforcing ribs are provided on the sides of the wedge body, extending along the length direction of the wedge body. By providing a textured structure on the upper surface of the wedge body, the friction force when in contact with the tire is effectively enhanced, improving anti-slip performance; the use of polyethylene material gives the parking wedge a certain degree of lightness and weather resistance, facilitating handling and long-term use; the friction iron plate structure at the bottom of the wedge body enhances the contact friction with the ground, improving overall stability; and the reinforcing ribs extending along the length direction on the sides of the wedge body help improve the structural strength of the wedge body under stress, preventing deformation or damage.

[0006] Preferably, the bottom surface of the friction plate structure has discrete three-dimensional protrusions arranged in a rectangular array, and fixing screws are provided between multiple discrete three-dimensional protrusions to fix them to the bottom of the wedge. The three-dimensional protrusion structure significantly increases the number of contact points between the friction plate and the ground, thereby improving the overall grip; the fixing screws firmly connect the friction plate to the bottom of the wedge, ensuring that the plate will not shift or fall off during use, thus improving reliability.

[0007] Preferably, the top surface of the friction plate and the bottom of the wedge are provided with a spring array structure, which includes miniature springs distributed in a rectangular array. The spring array structure can provide a buffering effect when the parking wedge is subjected to external impact, reducing direct impact damage to the wedge and the friction plate; the spring structure can also adapt to slight unevenness of the ground, enhancing the adaptability and stability of the parking wedge under different terrains; the buffering design helps to extend the service life of the parking wedge and reduce the risk of structural fatigue or damage caused by frequent pressure.

[0008] Preferably, the wedge texture structure comprises multiple diamond-shaped protrusions with a spacing between adjacent diamond-shaped protrusions ranging from 10 to 20 millimeters. Compared to other shapes, the diamond-shaped protrusion layout provides more friction contact points within the same area, enhancing the engagement between the tire and the wedge. A reasonable protrusion spacing design helps to improve friction while avoiding excessive density that could affect the manufacturing process or user experience. This structural design allows the parking wedge to maintain good anti-skid performance when facing different types of tires.

[0009] Preferably, the wedge width is 169.0 mm, the vertical distance between the highest point and the bottom of the wedge is 176.2 mm, the radius of the transition arc of the wedge is 449.2 mm, and the length of the wedge is 395.6 mm. Precise dimensional design ensures the parking wedge can be placed stably during use, preventing it from tipping over or sliding; reasonable size proportions allow the parking wedge to adapt to various vehicle models and parking environments, improving its versatility and practicality; the specific shape design helps optimize stress distribution, improving the overall structural stability and durability.

[0010] Preferably, the friction pad is made of ductile iron, and its surface is carburized and quenched to achieve a surface hardness of HRC50~55. Ductile iron has good strength and toughness, enabling it to withstand greater pressure and impact, thus improving the structural reliability of the friction pad. The carburizing and quenching treatment significantly improves its hardness and wear resistance, extending the service life of the friction pad. The high surface hardness makes the friction pad less prone to wear during long-term frictional contact with the ground, maintaining stable frictional performance.

[0011] The advantages of this utility model are: This parking wedge achieves a multi-dimensional collaborative design that integrates efficient anti-slip and stable support. The wedge body is made of polyethylene, offering advantages in both lightweight and weather resistance, making it easy to transport and suitable for long-term outdoor use. The diamond-patterned structure on the upper surface increases the number of contact points with the tire, significantly improving friction resistance with different types of tires and effectively preventing vehicle slippage. The added friction plate structure at the bottom further enhances the contact friction with the ground. The discrete three-dimensional protrusions distributed in a rectangular array greatly increase the density of ground contact points, and the secure connection with fixing screws ensures that the plate is not easily displaced or detached during long-term use, significantly enhancing the parking wedge's stability on ramps or... The parking wedge exhibits excellent anchoring capability on uneven ground. A spring array structure (composed of miniature springs arranged in a rectangular array) between the friction plate and the bottom of the wedge provides dynamic cushioning when vehicles run over it or the ground undulates slightly. This absorbs impact energy, reduces direct damage to the main structure, and adaptively adjusts the contact pressure to suit different terrains, enhancing the wedge's adaptability and durability in complex environments. The reinforcing ribs extending along the length of the sides optimize stress distribution, enhancing the wedge's overall resistance to compression and deformation, preventing structural failure due to long-term load-bearing or external impacts.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Example

[0022] Please see Figure 1-7As shown, a parking wedge with high friction includes a wedge body 1. The wedge body 1 is characterized by: a textured structure on its upper surface to increase friction; the wedge body 1 is made of polyethylene; a friction plate 4 structure is provided at the bottom of the wedge body 1; and reinforcing ribs 3 are provided on the sides of the wedge body 1, extending along the length of the wedge body 1. By providing a textured structure on the upper surface of the wedge body 1, the friction force when in contact with the tire is effectively enhanced, improving anti-slip performance. The use of polyethylene material gives the parking wedge a certain degree of lightness and weather resistance, facilitating handling and long-term use. The friction plate 4 structure at the bottom of the wedge body 1 enhances the contact friction with the ground, improving overall stability. The reinforcing ribs 3 extending along the length of the wedge body 1 on its sides help improve the structural strength of the wedge body 1 under stress, preventing deformation or damage.

[0023] In this embodiment, the bottom surface of the friction plate 4 is provided with discrete three-dimensional protrusions 6 arranged in a rectangular array, and fixing screws 7 are provided between multiple discrete three-dimensional protrusions 6 to fix them to the bottom of the wedge 1. The three-dimensional protrusion structure significantly increases the number of contact points between the friction plate 4 and the ground, thereby improving the overall grip; the fixing screws 7 firmly connect the friction plate 4 to the bottom of the wedge 1, ensuring that the plate will not shift or fall off during use, thus improving the reliability of use.

[0024] In this embodiment, the top surface of the friction plate 4 and the bottom of the wedge 1 are provided with a spring array structure, which includes miniature springs 5 ​​arranged in a rectangular array. The spring array structure can provide a buffering effect when the parking wedge is subjected to external impact, reducing direct impact damage to the wedge 1 and the friction plate; the spring structure can also adapt to slight unevenness of the ground, enhancing the adaptability and stability of the parking wedge under different terrains; the buffering design helps to extend the service life of the parking wedge and reduce the risk of structural fatigue or damage caused by frequent pressure.

[0025] In this embodiment, the textured structure of the wedge 1 includes multiple diamond-shaped protrusions 2, with the spacing between adjacent diamond-shaped protrusions 2 ranging from 10 to 20 millimeters. Compared to other shapes, the arrangement of the diamond-shaped protrusions 2 provides more friction contact points within the same area, enhancing the engagement between the tire and the wedge 1. The reasonable protrusion spacing design helps to improve friction while avoiding excessive density that could affect the manufacturing process or user experience. This structural design allows the parking wedge to maintain good anti-slip performance when facing different types of tires.

[0026] In this embodiment, the wedge 1 has a width of 169.0 mm, a vertical distance of 176.2 mm between its highest point and bottom, a radius of 449.2 mm for the transition arc, and a length of 395.6 mm. Precise dimensional design ensures the parking wedge can be placed stably during use, preventing it from tipping over or sliding. Reasonable size proportions allow the parking wedge to adapt to various vehicle models and parking environments, enhancing its versatility and practicality. The specific shape design helps optimize stress distribution, improving the overall structural stability and durability.

[0027] In this embodiment, the friction plate 4 is made of ductile iron, and its surface is carburized and quenched to achieve a surface hardness of HRC 50~55. Ductile iron has good strength and toughness, enabling it to withstand greater pressure and impact, thus improving the structural reliability of the friction plate 4. The carburizing and quenching treatment significantly improves its hardness and wear resistance, extending the service life of the friction plate 4. The high surface hardness makes the friction plate 4 less prone to wear during long-term frictional contact with the ground, maintaining stable frictional performance.

[0028] The implementation principle of this embodiment is as follows: When a vehicle needs to be secured, the operator places the parking wedge in the gap between the tire and the ground. First, the diamond-patterned structure on the upper surface of the parking wedge directly contacts the tire tread—the multi-directional interlocking design of the diamond protrusions 2 increases the effective contact area between the tire and the wedge 1, allowing the pressure applied by the tire to be distributed to more tiny contact points, thereby significantly increasing static friction and preventing the tire from sliding laterally. At the same time, the friction plate 4 at the bottom of the wedge 1 contacts the ground, and its rectangular array of discrete three-dimensional protrusions 6 further increases the number of friction contact points with the ground, enabling the parking wedge to form a multi-point anchoring effect on hard surfaces (such as cement and asphalt) or slightly uneven terrain, preventing overall slippage. The fixing screws 7 firmly connect the friction plate 4 to the bottom of the wedge 1, ensuring that the plate will not shift under vehicle pressure or external force, maintaining a stable friction support state.

[0029] When the vehicle's weight applies pressure or there are slight undulations in the ground, the spring array structure between the top of the friction plate 4 and the bottom of the wedge 1 begins to function. The buffer system formed by multiple micro springs 5 ​​arranged in a rectangular array can absorb some of the impact energy, reduce the direct transmission of pressure to the main structure of the wedge 1, and avoid deformation or damage caused by instantaneous high pressure. At the same time, the elastic properties of the springs allow the parking wedge to automatically adjust the contact pressure distribution according to the undulations of the ground, ensuring that the friction plate 4 is always in close contact with the ground and maintaining the best friction anchoring effect.

[0030] In addition, the reinforcing ribs 3 extending along the length of the side of the wedge 1 share the main pressure load during the stress process. By optimizing the stress distribution path, the risk of local stress concentration is reduced, making the wedge 1 less prone to structural failure problems such as bending and fracture during long-term load-bearing or frequent use.
