Description

Technical Field

[0001] This utility model relates to the field of protective gear technology, and in particular to a sliding body protective gear. Background Technology

[0002] In the field of modern sports protection, knee or elbow pads, as common personal protective equipment, play a crucial role in high-intensity sports, extreme sports, and everyday physical activities. Their main function is to prevent sports injuries by absorbing impact, dispersing pressure, and providing joint stability.

[0003] Most knee and elbow pads currently on the market use hard plastic shells as their outer protective structure, primarily intended to provide cushioning upon impact. However, these materials lack good elasticity and deformability, making it difficult to effectively absorb or disperse energy during severe impacts. In fact, some of the impact force may be directly transferred to the joints, thus weakening the overall protective effect. Secondly, the design philosophy of most protective gear on the market remains at the "static protection" stage, assuming the impact is a single vertical load, neglecting the complex mechanical environment that may occur during movement, such as multi-angle impacts, lateral displacement, and slippage. Therefore, in non-ideal fall scenarios, existing protective gear struggles to provide comprehensive and effective protection.

[0004] In addition, most knee or elbow pads can only be worn on specific areas, resulting in a limited range of protected areas and relatively simple functions. Utility Model Content

[0005] The main purpose of this invention is to provide a sliding body protector, which aims to improve the shortcomings of the prior art and solve the problem of poor protective effect of protective equipment.

[0006] To achieve the above objectives, this utility model proposes a sliding body protector, comprising:

[0007] Rolling element unit;

[0008] The rolling element unit includes multiple omnidirectional ball wheels and connecting components. Each omnidirectional ball wheel is provided with a lateral fixing hole. The connecting components pass through the lateral fixing holes of the multiple omnidirectional ball wheels in sequence to connect the multiple omnidirectional ball wheels.

[0009] Optionally, it also includes a buffer layer and a shaping layer, wherein the shaping layer is disposed on one side of the buffer layer, the rolling element unit is disposed on the other side of the buffer layer, and the plurality of omnidirectional ball wheels are arranged in an array on the surface of the buffer layer.

[0010] Optionally, the omnidirectional ball wheel includes a ball body and multiple connecting bodies, the multiple connecting bodies are connected to the ball body, and the lateral fixing hole is located on the connecting body.

[0011] Optionally, four connectors are provided, which are arranged circumferentially around the outer wall of the sphere body, and the four connectors are distributed at four corners on the circumference of the sphere body.

[0012] Optionally, each of the connectors includes at least one connecting arm, and the connecting arm and the ball body are an integral structure.

[0013] Optionally, the ball body includes a protective shell, a rolling ball, and a plurality of contact sliders. The plurality of contact sliders are disposed inside the protective shell, a portion of the rolling ball protrudes outside the protective shell, a portion of the rolling ball is located inside the protective shell, and the outer wall of the rolling ball is in contact with the plurality of contact sliders.

[0014] Optionally, the rolling ball is a hollow ball.

[0018] Beneficial effects: The sliding body protector proposed in this utility model uses omnidirectional ball wheels. With this design, when subjected to external impact, the omnidirectional ball wheels roll to dissipate the force, allowing the surface of the sliding body protector to slide relative to the contact surface (such as the ground or wall), thereby effectively reducing friction damage to the skin or joints.

[0037] Example 1

[0038] See Figures 1-3 As shown, Embodiment 1 of this utility model provides a sliding body protective gear, including a rolling element unit 1; the rolling element unit 1 includes multiple omnidirectional ball wheels 11, which are arranged in an array.

[0039] In this embodiment 1, the universal ball wheel 11 is provided with a vertical fixing hole, and the universal ball wheel 11 is fixed to the surface of the shaping layer 3 by fastening screws. A buffer layer 2 is provided below the shaping layer 3.

[0040] Since multiple omnidirectional ball wheels 11 are installed in an array, the material of their attachment layer should be as hard as possible. This way, the omnidirectional ball wheels 11 will not easily loosen or fall off under huge external impacts, making them suitable for protective equipment on flat or small curvature surfaces.

[0041] Example 2

[0042] The inventors considered that for protective equipment with large surface curvature, such as knee pads and elbow pads, the requirement that the attachment layer is not easily deformed and is impact-resistant would result in excessive pressure per unit area, causing the omnidirectional ball wheels to deform, be damaged, or fall off.

[0043] Based on this, Embodiment 2 provides a sliding body protector, see [link / reference]. Figures 4-6 As shown, the slidable body protection includes a rolling element unit 1; the rolling element unit 1 includes multiple omnidirectional ball wheels 11 and a connecting member 12. Each omnidirectional ball wheel 11 is provided with a lateral fixing hole 1121. The connecting member 12 passes through the lateral fixing holes 1121 of the multiple omnidirectional ball wheels 11 in sequence to connect the multiple omnidirectional ball wheels 11.

[0044] Specifically, each omnidirectional ball wheel 11 has the ability to roll in multiple directions, and by rolling, it converts some of the impact kinetic energy into rotational kinetic energy, so that the omnidirectional ball wheel 11 has a local buffering effect.

[0045] In this embodiment, the omnidirectional ball wheel 11 is used as a rolling unit, and multiple omnidirectional ball wheels 11 are connected by the connecting member 12, thereby realizing a large-area, deformable protective structure.

[0046] Specifically, the omnidirectional ball wheel 11 is provided with a transverse fixing hole 1121. This design allows multiple omnidirectional ball wheels 11 to be connected through the connecting member 12, thereby allowing relative rotation and slight displacement between two adjacent omnidirectional ball wheels 11. This enables the sliding body protector to bend freely to conform to the surface curvature of different parts of the body, thus overcoming the limitation of traditional protective equipment that can only be customized for specific body parts and cannot be used universally for different parts. As a result, the sliding body protector provided by this utility model embodiment has a wide range of applications and can meet the protection needs of different parts of the body.

[0047] Compared to traditional rigid protective gear or segmented protective gear, the sliding body protective gear provided in this embodiment of the invention adopts the above-mentioned structural design, which eliminates the need for mold making and shaping, thereby reducing production difficulty and saving production costs.

[0048] When an external force is applied to the surface of the sliding body protective gear, the omnidirectional ball wheel 11 converts part of the impact kinetic energy into rotational kinetic energy through rolling, thereby reducing the peak impact force. Secondly, the omnidirectional ball wheel 11 greatly reduces the coefficient of friction, allowing the protective gear surface to slide relative to the contact surface (such as the ground, wall, etc.), effectively reducing frictional damage to the skin or joints.

[0049] In one embodiment of this utility model, see Figure 4 As shown, the sliding body protection also includes a buffer layer 2 and a shaping layer 3. The shaping layer 3 is disposed on one side of the buffer layer 2, the rolling element unit 1 is disposed on the other side of the buffer layer 2, and multiple omnidirectional ball wheels 11 are arranged in an array on the surface of the buffer layer 2.

[0050] Specifically, see Figures 9-10As shown, when the sliding body armor is subjected to an impact from a flat ground, the impact force is applied to the buffer layer 2 through the multiple omnidirectional rollers 11 arranged in an array. The buffer layer 2 is locally compressed and instantly adapts to form an approximately flat surface, thus making the surface of the sliding body armor and the part in contact with the ground also approximately flat. In this way, the number of omnidirectional rollers 11 that are in instantaneous contact with the ground increases, thereby increasing the contact area between the sliding body armor and the ground. Through multi-point contact and elastic deformation, stress concentration at a few hard contact points is effectively avoided, preventing individual omnidirectional rollers 11 from cracking, deforming, or getting stuck due to excessive pressure. At the same time, the multiple omnidirectional rollers 11 roll slightly at the moment of contact with the ground, converting some of the impact kinetic energy into rotational kinetic energy, thereby reducing the peak impact force and reducing the destructiveness of the impact.

[0051] In one embodiment of this utility model, see Figure 6 As shown, the omnidirectional ball wheel 11 includes a ball body 111 and multiple connecting bodies 112. The multiple connecting bodies 112 are connected to the ball body 111, and the lateral fixing hole 1121 is located on the connecting body 112.

[0052] Specifically, the connector 112 is a structure that protrudes outward from the outer wall of the sphere body 111, and the connector 112 and the sphere body 111 are rigidly connected. The rigid connection includes, but is not limited to, integral molding and welding fixation.

[0053] Preferably, four connectors 112 are provided, which are arranged circumferentially around the outer wall of the sphere body 111, and are distributed at four corners around the sphere body 111.

[0054] In one embodiment of this utility model, the included angle between two adjacent connecting bodies 112 on the outer circumferential wall of the same spherical body 111 is 90 degrees. Specifically, the four connecting bodies 112 located on the outer wall of the same spherical body 111 are positioned at 0°, 90°, 180°, and 270° respectively, thus forming a cross-shaped symmetrical distribution. With this design, when multiple omnidirectional wheels 11 are arranged in an array on the surface of the buffer layer 2, the connecting bodies 112 between each omnidirectional wheel 11 point to the corresponding connecting bodies 112 on the adjacent omnidirectional wheel 11 in the same direction. More specifically, when the omnidirectional wheels 11 are arranged in a rectangular grid array, the connecting bodies 112 of adjacent omnidirectional wheels 11 (whether adjacent left and right or front and back) are naturally aligned, allowing the connecting member 12 to pass through. This eliminates the need for complex angle adjustments or customized connectors, greatly simplifying the assembly process, improving assembly efficiency, and reducing manufacturing costs.

[0055] In this embodiment, when a swivel wheel 11 bears a vertical load, the force can be effectively distributed to multiple swivel wheels 11 by pulling the four adjacent swivel wheels 11 in the four directions through the connecting member 12.

[0056] See Figure 4 , Figure 6 and Figure 7 As shown, each connector 112 includes at least one connecting arm 1122, and the connecting arm 1122 and the ball body 111 are an integral structure.

[0057] Specifically, the omnidirectional ball wheels 11 provided by this utility model are a first omnidirectional ball wheel and a second omnidirectional ball wheel. The first omnidirectional ball wheel includes a ball body 111 and four connecting bodies 112. The four connecting bodies 112 are arranged circumferentially around the outer wall of the ball body 111, and each connecting body 112 consists of only one connecting arm 1122. The four connecting arms 1122 are distributed in the plane at 0°, 90°, 180°, and 270°. The second omnidirectional ball wheel also includes a ball body 111 and four connecting bodies 112. The four connecting bodies 112 are arranged circumferentially around the outer wall of the ball body 111, and each connecting body 112 consists of two connecting arms 1122. There is a gap between two adjacent connecting arms 1122, and the width of the gap is greater than the thickness of a single connecting arm 1122.

[0058] In one embodiment of this utility model, see Figure 4 As shown, the first and second universal ball wheels are alternately distributed on the surface of the buffer layer 2. With this design, the connecting arm 1122 of the first universal ball wheel can be inserted into the gap between the two connecting arms 1122 of the adjacent second universal ball wheel, so that the transverse fixing holes 1121 on the connecting arm 1122 of the first universal ball wheel and the transverse fixing holes 1121 on the two connecting arms 1122 of the second universal ball wheel are aligned. The metal wire can pass through the coaxial transverse fixing holes 1121 on the three adjacent connecting arms 1122 at one time, realizing efficient assembly of "one through three", thereby improving the assembly efficiency.

[0059] Secondly, the first and second omnidirectional wheels are alternately distributed on a two-dimensional plane to form a mesh-like interlocking network, which further eliminates lateral and longitudinal gaps. On the buffer layer 2 with the same surface area, more omnidirectional wheels 11 can be arranged, thereby significantly enhancing the impact resistance of the sliding body protective gear.

[0060] In one embodiment of this utility model, see Figure 8As shown, the ball body 111 includes a protective shell 1111, a rolling ball 1112, and a plurality of contact sliders 1113. The plurality of contact sliders 1113 are disposed inside the protective shell 1111. A portion of the rolling ball 1112 protrudes outside the protective shell 1111, while a portion of the rolling ball 1112 is located inside the protective shell 1111. The outer wall of the rolling ball 1112 is in contact with the plurality of contact sliders 1113.

[0061] Specifically, the contact ball 1112 and the contact slider 1113, as well as the contact slider 1113 and the inner wall of the protective shell 1111, are all point contacts. When an external force is applied to the exposed ball 1112, the ball 1112 rotates and is transmitted to the multiple contact sliders 1113 that are in contact with it through point contact. After being subjected to the force of the ball 1112, the multiple contact sliders 1113 also roll. In this way, the large-area sliding friction that originally occurred between the ball 1112 and the protective shell 1111 is decomposed and transformed into rolling friction on multiple tiny contact points. Since the static friction coefficient of rolling friction is much lower than that of sliding friction, this design makes the ball 1112 easier to start and more sensitive when subjected to a slight external force, significantly reducing the force required for starting. This allows the sliding body protective gear to respond instantly and roll to dissipate the force when subjected to an instantaneous impact force with uncertain direction.

[0062] It is worth mentioning that, since multiple contact sliders 1113 are distributed around the rolling ball 1112, no matter which direction the rolling ball 1112 rotates, some of the contact sliders 1113 will always be in a favorable rolling position, ensuring smooth rolling in any direction.

[0063] In one embodiment of this utility model, in order to reduce the overall weight of the sliding body armor for easy carrying, the rolling ball 1112 is a hollow ball.

[0064] Specifically, the 1112 ball has a hollow ball structure, which reduces the overall weight of the sliding body armor and greatly improves wearing comfort. It is especially suitable for situations that require long-term wear or coverage of large body parts, making users more willing to wear lightweight sliding body armor for extended periods and thus improving the actual achievement rate of protective effect.

[0065] Specifically, the materials used to make the rolling ball 1112 provided in this embodiment include, but are not limited to, metals, alloys, ceramics, carbon fibers, plastics, nylon, polyurethane, and other materials.

[0066] Specifically, the buffer layer 2 includes, but is not limited to, foam, sponge, cotton cloth, spring or spring. Buffer layers 2 made of other materials should also be within the scope of protection of this application as long as they can achieve the technical effects disclosed in this application. Therefore, this application does not make specific limitations on this.

[0067] Specifically, the shaping layer 3 includes, but is not limited to, metal, carbon fiber, plastic or wood. Shaping layers 3 made of other materials should also be within the scope of protection of this application as long as they can achieve the technical effects disclosed in this application. Therefore, this application does not make specific limitations in this regard.

[0068] In summary, the sliding body protector provided by this utility model has at least the following beneficial effects compared with the prior art, as detailed below:

[0069] 1. By the relative rotation and slight displacement between adjacent omnidirectional ball wheels 11, the sliding body armor can bend freely to conform to the surface curvature of different parts of the body, thus overcoming the limitation of traditional protective equipment that can only be customized for specific body parts (such as knees and elbows of specific shapes) and cannot be used in different parts.

[0070] 2. When subjected to external impact, the omnidirectional ball wheel 11 rolls to dissipate force, allowing the surface of the slidable body protective gear to slide relative to the contact surface (such as the ground or wall), thereby effectively reducing friction damage to the skin or joints.

[0071] 3. The sliding body protection gear adapts to the body's curved surface through the arrangement of 11 omnidirectional ball wheels, eliminating the need for mold making for different parts, saving on customized processing and reducing production complexity.

[0072] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
