Description

Technical Field

[0001] The invention relates to the technical field of automobile protection, in particular to a wall corner automobile scratch protector for an underground garage. Background Art

[0002] Car scratches are common in daily life, and underground garages are often the hardest hit areas. Figure 1 As shown in the image above, the scratches on the walls and pillars of an underground garage indicate that many vehicles are particularly prone to scratches around the sharp bends in the driveway. Repair costs for a scratch on a car's surface can range from a few hundred yuan to several thousand yuan.

[0003] Underground garages are often hostile to driving due to factors such as steep turns, numerous columns, and low lighting. This can lead to drivers scraping their cars against columns or walls, causing extensive damage, dents, or even rollovers. This can not only cause significant financial and time losses for drivers, but also physical and psychological harm to passengers.

[0004] Now, although some column heads are equipped with anti-collision rubber pads, such as Figure 2 As shown, this anti-collision rubber pad lacks sufficient buffer distance and lacks substantial anti-collision effect in actual application, which still causes large-scale damage and dents on the car surface. Summary of the Invention

[0005] The present invention aims to provide a wall corner car scratch protector for underground garages, resolving the current technical problem of a lack of effective scratch protection devices for underground garage corners. The wall corner car scratch protector designed by the present invention reduces or even eliminates sliding friction between the wall and the car surface by rotating at the point of contact with the car, thereby protecting the car's surface quality and preventing scratches. Furthermore, by providing elastic deformation on the horizontal plane, the device provides a buffer space when the car approaches the wall. This not only prevents deformation of the car's exterior due to contact with the wall, but also protects the car's surface quality and the safety of the driver and passengers.

[0006] The technical solution adopted in the present invention is as follows:

[0007] An automobile scratch protector for a wall corner in an underground garage comprises a support assembly and a rotating assembly. The rotating assembly comprises a rotating shaft and a plurality of elastic contact members. The axis of the rotating shaft is perpendicular to the ground. The contact members are arranged along the axis of the rotating shaft and are all sleeved on the rotating shaft.

[0008] The support assembly is fixed on the wall, and there are two support assemblies, which are respectively located at the upper and lower ends of the rotating shaft. The upper and lower ends of the rotating shaft are respectively rotatably connected to one support assembly, and the rotating shaft can rotate around its own axis relative to the support assembly.

[0009] Furthermore, the contact member includes an elastic connecting ring and a plurality of rubber strips, the connecting ring is an open ring, one end of the rubber strip is connected to the outer wall of the connecting ring, and the rubber strips are uniformly distributed along the outer circumference of the connecting ring;

[0010] The length of the circumference of the inner ring of the connecting ring is consistent with the circumference of the cross section of the rotating shaft, and the inner ring of the connecting ring is connected to the side wall of the rotating shaft through Velcro.

[0011] Furthermore, the rubber strip extends obliquely downward, and the distance from the rubber strip to the axis of the rotating shaft gradually increases as it moves away from the open ring; and the spacing between two circumferentially adjacent rubber strips gradually increases as it moves away from the open ring.

[0012] Furthermore, an elastic support ring is provided on the inner side of each of the contact members. The support ring is a conical ring, which is sleeved on the rotating shaft, and the conical surface of the support ring contacts the top of the inner side surface of the rubber strip.

[0013] Furthermore, the support ring is an open ring, the inner ring of which is connected to the rotating shaft by Velcro, and a through groove is provided on the conical surface of the support ring. The extension axis of the through groove is parallel to the axis of the rotating shaft, and there are multiple through grooves, which are evenly distributed in sequence along the outer circumference of the support ring.

[0014] Furthermore, the connecting ring, the rubber strip and the supporting ring are all made of waste tires.

[0015] Furthermore, the support assembly includes a screw, a connecting block, a tightening nut, a positioning nut and a bearing, a mounting hole is provided on the connecting block, the axis of the mounting hole coincides with the axis of the rotating shaft, and the inner and outer rings of the bearing are interference fit with the rotating shaft and the mounting hole respectively;

[0016] One end of the screw is threadedly connected to the positioning nut, and the other end passes through the connecting block and is threadedly connected to the tightening nut. The end faces of the tightening nut and the positioning nut are in contact with the side wall of the connecting block, and one end of the screw is connected to the wall.

[0017] Furthermore, a buffer assembly is provided between the support assembly and the wall, and the buffer assembly includes a plate A, a buffer spring and a plate B connected in sequence. The plate A is connected to the support assembly, and the two ends of the buffer spring are respectively connected to the plate A and the plate B. The plate B is fixed to the wall by screws.

[0018] Furthermore, a roller is provided at the bottom of the support assembly located at the lower side of the rotating shaft. The roller is a universal wheel, and its connecting plate is connected to the support assembly.

[0019] Furthermore, there are seven contact members.

[0020] Due to the adoption of this technical solution, the beneficial effects of the present invention are:

[0021] 1. The present invention's car corner scratch protector for underground garages reduces or even eliminates sliding friction between the wall and the car surface by rotating at the contact point with the car, thereby protecting the car's surface quality and preventing scratches. Furthermore, by adding elastic deformation on the horizontal plane, this elastic deformation provides a buffer space for the car to approach the wall. This not only prevents the car from colliding with the wall and causing compression and deformation of the exterior, but also protects the car's surface quality and the safety of the driver and passengers, preventing sudden collisions.

[0022] 2. The car scratch protector for the corner surface of the underground garage of the present invention is an open ring, which is convenient for quickly putting it on the rotating shaft through its own opening, or removing it from the rotating shaft, which reduces the manufacturing difficulty of the present invention and improves the convenience of the later maintenance of the present invention. The parent surface of the Velcro is fixed on the connecting ring, and the child surface of the Velcro is fixed on the rotating shaft. When it is necessary to install the connecting ring on the rotating shaft, the opening of the connecting ring is expanded, and then the rotating shaft is inserted into the connecting ring through the opening, and then the connecting ring is pressed so that the parent surface and the child surface of the Velcro are hooked to each other. When it is necessary to remove the connecting ring from the rotating shaft 1, the connecting ring is bent through the opening to expand the opening of the connecting ring, and then the rotating shaft is withdrawn from the center hole of the connecting ring through the opening. While withdrawing, it is necessary to apply force to release the hook between the parent surface and the child surface of the Velcro;

[0023] 3. The present invention's corner car scratch protector for underground garages increases the car's cushioning space when it strikes the contact element and continues to move toward the wall. The buffer spring compresses, providing a buffer space for the car to move closer to the wall and preventing deformation of the car's outer shape from contact with the wall. When the car passes, the buffer spring returns to its original position, and the central axis returns to its original position. By providing the buffer spring and other components, the present invention increases the cushioning space for the car, further optimizing its protection.

[0024] 4. The car scratch protector for the wall corner of the underground garage of the present invention has contact parts and other components made of waste tires, which improves the utilization rate of waste and reduces the manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] 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 embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein may be arranged and designed in various different configurations.

[0043] Unless otherwise specified, "connection" in the present invention refers to conventional connection methods, such as integral molding, welding, riveting, etc. The specific connection method can be adaptively optimized based on conventional technical knowledge in this technical field. All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any manner.

[0044] The following combination Figures 3 to 14 The present invention is described in detail.

[0045] Example 1

[0046] like Figure 3-Figure 14 As shown, the present invention provides a car scratch protector for a corner wall of an underground garage, comprising a support assembly and a rotating assembly. The rotating assembly comprises a rotating shaft 1 and a plurality of elastic contact members 2. The axis of the rotating shaft 1 is perpendicular to the ground. The contact members 2 are arranged along the axis of the rotating shaft 1, and the contact members 2 are all sleeved on the rotating shaft 1.

[0047] The support assembly is fixed on the wall, and there are two support assemblies, which are respectively located at the upper and lower ends of the rotating shaft 1. The upper and lower ends of the rotating shaft 1 are respectively rotatably connected to a support assembly, and the rotating shaft 1 can rotate around its own axis relative to the support assembly.

[0048] Contact member 2 can be a rubber component of any shape capable of elastically contracting in a horizontal plane, such as a small tire or a rubber strip. Contact member 2 can also be constructed as an airbag, or comprised of a spring and a soft ball. The specific form of contact member 2 is not limited, as long as it can elastically contract in a horizontal plane.

[0049] If a vehicle is scratched while driving, the wall will generate a dynamic friction force in the opposite direction of the vehicle's travel and a squeezing force directed toward the vehicle body. These two forces will cause the paint to be scratched or the surface of the vehicle to be dented. Figure 12As shown, the surface of the car is not in direct contact with the wall. When the car approaches the wall, the car first contacts the contact piece 2 mounted on the rotating shaft. The static friction between the car and the contact piece 2 drives the contact piece 2 to rotate around the axis of the rotating shaft 1, thereby eliminating the sliding friction between the car and the contact surface. This will not damage the car paint, prevent the car surface from being scratched, and protect the surface quality of the car.

[0050] At the same time, if the car still tends to move toward the wall, contact element 2 will be compressed, providing a buffer space for the car to approach the wall and prevent the car from being deformed by pressure when it contacts the wall. When the car passes, contact element 2 returns to its original state due to its own elasticity, preparing for the next car protection.

[0051] The car scratch protector designed for underground garage corners reduces or even eliminates the sliding friction between the wall and the car surface by rotating at the contact point with the car, thereby protecting the car surface quality and preventing scratches. At the same time, by adding an elastic deformation function on the horizontal plane, a buffer space is provided for the car to approach the wall through this elastic deformation function, which not only avoids the car colliding with the wall and causing compression deformation of the outer shape, but also protects the car surface quality and the safety of the driver and passengers, and prevents sudden collisions.

[0052] Example 2

[0053] This embodiment provides a specific implementation description of the contact element 2.

[0054] like Figure 3-Figure 9 As shown, in the present invention, the contact member 2 includes an elastic connecting ring 3 and a plurality of rubber strips 4. The connecting ring 3 is an open ring. One end of the rubber strip 4 is connected to the outer wall of the connecting ring 3, and the rubber strips 4 are uniformly distributed along the outer circumference of the connecting ring 3.

[0055] The length of the circumference of the inner ring of the connecting ring 3 is consistent with the circumference of the cross section of the rotating shaft 1 , and the inner ring of the connecting ring 3 is connected to the side wall of the rotating shaft 1 via Velcro.

[0056] The connecting ring 3 is an open ring, which is convenient for quickly putting it on the rotating shaft 1 through its own opening, or removing it from the rotating shaft 1, which reduces the manufacturing difficulty of the present invention and improves the convenience of the later maintenance of the present invention. The parent surface of the Velcro is fixed on the connecting ring 3, and the child surface of the Velcro is fixed on the rotating shaft 1. When it is necessary to install the connecting ring 3 on the rotating shaft 1, the opening of the connecting ring 3 is expanded, and then the rotating shaft 1 is inserted into the connecting ring 3 through this opening, and then the connecting ring 3 is pressed so that the parent surface and the child surface of the Velcro are hooked together. When it is necessary to remove the connecting ring 3 from the rotating shaft 1, the connecting ring 3 is bent through the opening to expand the opening of the connecting ring 3, and then the rotating shaft 1 is withdrawn from the center hole of the connecting ring 3 through this opening. While withdrawing, it is necessary to apply force to release the parent surface and the child surface of the Velcro from being hooked together.

[0057] Furthermore, the rubber strip 4 extends obliquely downward, and its distance from the axis of the rotating shaft 1 gradually increases as it moves away from the open ring 3 ; the spacing between two adjacent rubber strips 4 in the circumferential direction gradually increases as it moves away from the open ring 3 .

[0058] Furthermore, an elastic support ring 5 is provided on the inner side of each of the contact members 2 . The support ring 5 is a conical ring that is sleeved on the rotating shaft 1 , and its conical surface contacts the top of the inner side surface of the rubber strip 4 .

[0059] Furthermore, the support ring 5 is an open ring, the inner ring of which is connected to the rotating shaft 1 by Velcro, and a through groove 6 is provided on the conical surface of the support ring 5. The extension axis of the through groove 6 is parallel to the axis of the rotating shaft 1, and there are multiple through grooves 6, which are evenly distributed in sequence along the outer circumference of the support ring 5.

[0060] The support ring 5 is provided to support the rubber strip 4, thereby reducing the stress at the connection portion between the rubber strip 4 whose bottom end is suspended and the connecting ring 3. When the rubber strip 4 is squeezed by the car, the support ring 5 can reduce the impact on the connection portion between the rubber strip 4 and the connecting ring 3, thereby improving the service life of the present invention.

[0061] Furthermore, the connecting ring 3, rubber strip 4, and support ring 5 are all made from waste tires. The contact member 2 and other components are made from waste tires, which improves waste utilization and reduces manufacturing costs. The rubber strip 4 is preferably bonded to the connecting ring 3. If the rubber strip 4 wears out, only the contact member 2 needs to be replaced. The present invention is assembled from various components, all of which are readily available on the market, making replacement easy and cost-effective.

[0062] Example 3

[0063] This embodiment illustrates the implementation structure of the support assembly.

[0064] like Figure 3-Figure 6As shown, in the present invention, the support assembly includes a screw 7, a connecting block 8, a tightening nut 9, a positioning nut 10 and a bearing 11. A mounting hole 12 is provided on the connecting block 8. The axis of the mounting hole 12 coincides with the axis of the rotating shaft 1. The inner and outer rings of the bearing 11 are interference fit with the rotating shaft 1 and the mounting hole 12 respectively.

[0065] One end of the screw rod 7 is threadedly connected to the positioning nut 10, and the other end thereof passes through the connecting block 8 and is threadedly connected to the tightening nut 9, and the end faces of the tightening nut 9 and the positioning nut 10 are in contact with the side wall of the connecting block 8, and one end of the screw rod 7 is connected to the wall.

[0066] Tightening the nut 9 and the positioning nut 10 fixes the connecting block 8 and the screw rod 7 to each other, which facilitates the installation of the connecting block 8 and subsequent maintenance.

[0067] The support assembly can also adopt the structural form of a bearing seat.

[0068] like Figure 4 As shown, in actual use, it is required that the projection of the end of the screw 7 away from the wall in the horizontal plane is located in the projection of the rotating shaft 1 in the horizontal plane. Therefore, it is preferred that a small-diameter shaft body is formed on the end of the rotating shaft 1, and its outer diameter is smaller than the outer diameter of the rotating shaft 1. The small-diameter shaft body is inserted into the mounting hole 12, and the inner and outer rings of the bearing 11 are respectively interference-fitted with the small-diameter shaft body and the mounting hole 12, as shown in FIG. Figure 6 similarly, the outer diameter of the connecting block 8 is also smaller than the outer diameter of the rotating shaft 1.

[0069] Example 4

[0070] This embodiment further illustrates the present invention.

[0071] like Figure 3-Figure 4 As shown, in the present invention, a buffer assembly is provided between the support assembly and the wall, and the buffer assembly includes a plate A13, a buffer spring 14 and a plate B15 connected in sequence. The plate A13 is connected to the support assembly, and the two ends of the buffer spring 14 are respectively connected to the plate A13 and the plate B15. The plate B15 is fixed to the wall by screws 16.

[0072] During driving, if the car continues to move toward the wall after hitting the contact member 2, the buffer spring 14 will be compressed, thereby providing a buffer space for the car to approach the wall and prevent the car's outer shape from being deformed by pressure when contacting the wall. When the car passes, the buffer spring returns to its original state and the central axis returns to its original position. By providing the buffer spring 14 and other components, the present invention increases the buffer space for the car and further optimizes the protection of the car.

[0073] Example 5

[0074] This embodiment further optimizes and explains the present invention based on the fourth embodiment.

[0075] In Example 4, the buffer spring 14 is a flexible part, which has poor support for the rotating shaft 1 and other components in the vertical direction. Therefore, in order to reduce the deformation of the buffer spring 14 in the non-axial direction, it is preferably necessary to make the support assembly located below the rotating shaft 1 contact the ground so that the rotating shaft 1 and other components are supported by the ground; however, in this case, there is sliding friction between the present invention and the ground, which increases the unnecessary friction of the present invention, thereby increasing the triggering force of the buffer of the present invention, which is not conducive to its timely buffering and protecting the car. Therefore, in the present invention, a roller 17 is provided at the bottom of the support assembly located on the lower side of the rotating shaft 1. The roller 17 is a universal wheel, and its connecting plate is connected to the support assembly. The roller 17 not only allows the rotating shaft 1 and other components to be supported by the ground, but also makes the friction between the present invention and the ground rolling friction, which greatly reduces the friction between the present invention and the ground, and is conducive to the present invention being triggered in time to play a buffering and protecting role for the car.

[0076] Example 6

[0077] This embodiment provides an implementation description of the installation and use of the present invention.

[0078] like Figure 3-Figure 5 As shown, there are seven contact elements 2 .

[0079] When the present invention is installed on a plane wall, its installation diagram is as follows: Figure 13 When the present invention is installed on a curved wall, its installation diagram is as shown Figure 14 shown.

[0080] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be conceived by a person skilled in the art within the technical scope disclosed by the present invention without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
