A zither tooth protection plate

Abstract

This invention provides a kite-tooth protective plate, comprising a plate body, with multiple micro-element protrusions arranged parallel to each other on one side of the plate body exposed to attack. The other side of the plate body has kite-shaped grooves corresponding to the micro-element protrusions, with the side extension line of each micro-element protrusion coinciding with the side extension line of either the kite-shaped groove or the side extension line of the kite-shaped groove. This kite-tooth protective plate, in its cross-sectional design, employs a scheme composed of multi-scale kite-shaped micro-elements, thereby maintaining the overall perpendicularity of the protective plate to the horizontal plane while ensuring that each micro-element surface of the protective plate maintains a certain angle with the horizontal plane, enhancing the protective plate's ability to protect against directional intrusions.

Description

Technical Field

[0001] This invention belongs to the field of protection, and in particular relates to a zither tooth protective plate. Background Technology

[0002] In the field of safety protection, barriers are a common protective tool for directional response to the impact of flying foreign objects. However, in engineering practice, conventional flat protective barriers save installation space when installed vertically, but they can only rely on their own thickness to resist the intruder. Therefore, thick plates are generally required, making the whole structure relatively bulky, and the intruder can easily damage the protected target when it penetrates the barrier. When conventional flat protective barriers are installed at an angle, although they can provide a certain longitudinal asymmetrical force and achieve a higher effective horizontal protection thickness with a thinner plate, they require a large installation space and are more prone to protection failure when the intruder changes direction. Summary of the Invention

[0003] In view of this, the present invention aims to provide a kite tooth protective plate to improve the protective strength of the protective plate.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0005] A kite-shaped protective plate includes a plate body, and a plurality of micro-element protrusions are provided on one side of the plate body that is subject to attack. The plurality of micro-element protrusions are arranged in parallel with each other. A kite-shaped groove corresponding to the micro-element protrusions is provided on the other side of the plate body. The side extension line of each micro-element protrusion coincides with the side extension line of the kite-shaped groove.

[0006] Furthermore, the shape of the micro-element protrusion can be any one of kite-shaped, rhomboid, or square.

[0007] Furthermore, a support protrusion is provided between each pair of micro-element protrusions.

[0008] Furthermore, the micro-element protrusion, the support protrusion, and the plate body are an integral structure.

[0009] Furthermore, buffer components are provided on one or both sides of the plate body.

[0010] Furthermore, a baffle plate is provided on the side of the plate body away from the side being attacked.

[0011] Furthermore, the kite tooth protective plate includes multiple plate bodies arranged in parallel to each other, with gaps between each pair of plate bodies. The gaps are filled with buffer components, and a baffle plate is provided on the outer side of the plate body away from the side being attacked.

[0012] Compared with the prior art, the kite-tooth protective plate of the present invention has the following beneficial effects: the kite-tooth protective plate with micro-element protrusions adopts multi-scale kite-shaped micro-element splicing in cross-sectional shape. At the same time, the rear extension line of the front kite-shaped micro-element coincides with the rear kite-shaped micro-element inside or with the rear edge of the rear kite-shaped micro-element. Thus, while keeping the overall protective plate perpendicular to the horizontal plane, each micro-element surface has a certain angle with the horizontal plane. This increases the effective protection thickness in the horizontal direction while keeping the thickness of the micro-element plate constant. It also ensures that the vertical protection thickness of each micro-element surface is approximately greater than or equal to twice the thickness of the micro-element plate, improving the protective effect of the protective plate when the intruder turns to the right direction. Furthermore, it increases the longitudinal asymmetric force when the intruder reaches the plate surface in most cases, increasing the possibility of the intruder's movement direction shifting upwards and downwards away from the protected object.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] First embodiment:

[0025] like Figure 1 As shown, a kite-tooth protective plate includes a plate body 1, with multiple micro-element protrusions 2 arranged parallel to each other on one side of the plate body 1 that is subject to attack. The other side of the plate body 1 has kite-shaped grooves 3 corresponding to the micro-element protrusions 2. The side extension line of each micro-element protrusion 2 coincides with the side edge of the kite-shaped groove 3. Compared with conventional planar protective plates, the kite-tooth protective plate with micro-element protrusions 2 adopts a multi-scale kite-shaped micro-element splicing in its cross-sectional shape. Simultaneously, the rear extension line of the front kite-shaped micro-element coincides with or is located inside the rear kite-shaped micro-element. This design ensures that each micro-element surface has a certain angle with the horizontal plane while maintaining the overall perpendicularity of the protective plate. This increases the effective protection thickness in the horizontal direction while keeping the thickness of the micro-element plate constant. It also ensures that the vertical protection thickness of each micro-element surface is approximately greater than or equal to twice the thickness of the micro-element plate, thus improving the protective effect of the protective plate when the intruder changes direction. Furthermore, it increases the longitudinal asymmetric force when the intruder reaches the plate surface in most cases, increasing the possibility that the intruder's movement direction will shift upwards and downwards, away from the protected object.

[0026] like Figures 1-4 As shown, the number of columns of protrusions in the kite-shaped micro-element can be two to infinite; the shape parameters of each column of micro-element can be the same or different; the shape parameters of micro-element in the same column can be the same or different; the shape of the micro-element can be a regular kite shape, or a special shape such as a rhombus or a square.

[0027] The cross-sectional shape of a kite-shaped protective plate can be a simple structure based on the superposition of micro-element protrusions 2 in the kite-shaped micro-element, or a complex structure obtained by adding other shapes on the basis of the simple structure. Alternatively, materials can be added to the recessed area in front or behind the protective plate to change the local shape (such as back filling).

[0028] Second embodiment:

[0029] The difference from the first embodiment is that in the second embodiment, a support protrusion 4 is provided between the two micro-element protrusions 2. The support protrusion 4 can increase the structural strength of this part and improve the structural strength of the protective plate. Moreover, the micro-element protrusion 2, the support protrusion 4 and the plate body 1 are an integral structure.

[0030] Third embodiment:

[0031] The difference between the third embodiment and the first embodiment is that the side extension line of the micro-element protrusion 2 coincides with the side extension line of the kite-shaped groove.

[0032] Fourth embodiment:

[0033] The difference between the fourth embodiment and the third embodiment is that the actual application of the plate body 1 can be either using a simple prototype plate or adding a structure such as a mesh grid or adding composite materials to the front and back of the plate body 1 to obtain a buffer component.

[0034] The kite-tooth protective plate described in this embodiment adopts a cross-sectional shape composed of multi-scale kite-shaped micro-elements. This ensures that each micro-element surface of the plate body 1 maintains a certain angle with the horizontal plane while keeping the plate body 1 perpendicular to the horizontal plane, thereby enhancing the plate body 1's ability to protect against directional intruders.

[0035] Fifth embodiment:

[0036] Unlike the fourth embodiment, this embodiment provides multiple board bodies 1, which are arranged in parallel to each other. There is a gap between each pair of board bodies 1, and the gap is filled with a buffer component. The buffer component can be a wooden board, composite board, or resin board. A baffle plate is provided on the outer side of the board body away from the side being attacked.

[0037] Application effects in practical use:

[0038] 1. When the intruder flies in and turns to the center upon reaching the plate surface, the direction of the force exerted by the intruder will change to the normal direction of the micro-element surface. At this time, the actual protective thickness of the plate body 1 becomes twice the plate thickness, and the protective effect of the plate body 1 on the protected target is relatively enhanced compared to the vertical plate or the inclined plate.

[0039] 2. When the intruder arrives without undergoing a normalization motion, if the incident point falls into the front inclined area of ​​plate body 1, the intruder will be affected by longitudinal asymmetrical forces during the collision with plate body 1:

[0040] a) If the longitudinal asymmetric force has a strong influence on the direction of motion of the intruder, the velocity vector of the intruder will shift to the upper and lower sides and move away from the protected object. At this time, the plate body 1 achieves full protection of the protected target.

[0041] b) If the longitudinal asymmetric force has a weak effect on the direction of motion of the intruder, the velocity vector of the intruder continues to remain approximately horizontal with the horizontal direction. The effective protective thickness of the plate body 1 is greater than the actual vertical plate thickness due to the inclination of the micro-element surface. At this time, the protective effect of the plate body 1 on the protected target is enhanced relative to the vertical plate.

[0042] 3. When the intruder flies in and does not turn to the center, if the incident point is exactly at the tip of the peak of plate body 1, the protective effect is in principle the same as (a), and the protective effect is enhanced relative to the vertical plate.

[0043] 4. When local peaks are added to weak points such as the valley bottom in front of the plate body 1 using small-scale kite-shaped units, the probability of the incident trajectory moving away from the original valley bottom direction will increase, thereby improving the minimum protection capability.

[0044] 5. When a composite protection design is adopted (composite material buffer and support backplate are added sequentially behind the kite tooth plate), multiple protections such as buffering by the filler and interception by the backplate can be achieved on the basis of the original protection capability, thereby enhancing the protection effect.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
