Description

Technical Field

[0001] This utility model belongs to the field of armor protection for light tanks and armored vehicles, and specifically relates to a strap-type armor mounting structure. Background Technology

[0002] Adding composite armor has become an effective means of improving the protection performance of tanks and armored vehicles. Currently, the most common method of addition in domestic products is bolt connection, which involves welding bolts of a certain size to the base and drilling holes in the composite armor component, connecting the two with nuts. This connection method can ensure a tight fit between the armor component and the base, preventing the armor component from loosening or even falling off during long-term vehicle use. However, after drilling holes in the composite armor component, stress deformation or even structural damage may occur at the edge of the holes, making this area a weak point and severely reducing the effective protection area of ​​the armor component. Clamping is also used in some domestic models. To provide connection strength to the entire panel area, this connection method often requires adding a metal encapsulation shell to the outside of the composite armor, which increases the weight of the armor component, and the area around the clamping block is also a weak point. For some vehicles with complex electronic components on the roof, welding large bolts is not suitable, so adhesive is used to fix the composite armor component to the vehicle body. However, due to the lack of tangential constraint, this connection method is only suitable for the vehicle roof, and the connection strength is greatly limited by the usage environment and the shelf life of the adhesive. Utility Model Content

[0003] Addressing the problems of current installation methods such as bolted connections, pressure block fixation, and adhesive bonding, this invention provides a strap-on armor installation structure. This involves welding metal fasteners arranged vertically and horizontally onto the vehicle substrate, and connecting them with straps equipped with tensioners to achieve a tight and rapid installation of the composite armor. This overcomes the problem of bolted connections reducing the effective protective area and the low connection strength of adhesive bonding. Compared to pressure block fixation, it eliminates the need for an additional metal shell, making the method simple and efficient. The specific technical solution is as follows.

[0004] A strap-type armor mounting structure includes a metal fastener, a strap, a tensioner, and a composite armor component. The metal fastener is made of the same material as the armored vehicle's base and is vertically welded to the base in a "symmetrical" manner. A square hole is opened at the top of the metal fastener, the size of which matches the width and thickness of the strap to ensure the strap can be easily inserted. The composite armor component is fixed in the middle of the metal fastener. One end of the strap is fixedly connected to one end of the tensioner, and the other end passes through the square hole in the upper or left side of the metal fastener and exits through the square hole in the lower or right side of the symmetrical part of the metal fastener. The exiting strap connects to the other end of the tensioner. The tensioner's self-tightening function keeps the strap taut, ensuring a tight connection between the composite armor component and the armored vehicle's base.

[0005] Furthermore, the width, number, and installation position of the metal fixing buckles are determined according to the shape and size of the composite armor component, and the height is consistent with that of the composite armor component.

[0006] Furthermore, the binding straps have a certain tensile strength, ensuring a breaking tensile force ≥8kN. At least two binding straps are provided on the top and bottom, and two on the left and right sides. The specific number is determined according to the size and weight of the armor piece.

[0007] Furthermore, the composite armor component is ballistic armor consisting of metal armor or ceramic composite armor that has the function of protecting against bullets or small-caliber artillery shells.

[0008] The distance, number, and installation position of the metal fasteners are determined based on the shape and size of the composite armor component, ensuring that the composite armor component can be placed between the vertically and horizontally distributed metal fasteners. The vertical and horizontal distances between the metal fasteners must be greater than the width and length of the composite armor, allowing sufficient installation slack for the binding straps. The height of the metal fasteners is consistent with the height of the composite armor component, ensuring that the binding straps can tightly restrain the composite armor component.

[0009] Beneficial effects of this utility model

[0010] This invention overcomes the problems of low strength and poor environmental adaptability of adhesive-based installation structures. Compared with bolted connections, the strap-on armor mounting structure designed in this invention does not require manual drilling of mounting holes, offering advantages such as convenient assembly and disassembly without reducing the effective protective area of ​​the armor components. It effectively avoids weak points in protection and ensures the effective protective area. The metal fixing buckles welded to the base not only provide support for the armor components but also serve to connect the straps. The self-tightening metal buckles tighten the straps, ensuring a tight fit between the armor components and the base during vehicle use. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Example 1

[0016] This embodiment uses a vehicle made of armor steel and installs a composite armor piece 4 with dimensions of 580×425×60mm. As an example, the following description of the embodiment is based on the accompanying drawings:

[0017] (1) Select armor steel with a length of 30mm, a thickness of 5mm and a height of 60mm as metal fixing buckle 1. Make a "square" hole with a length of 28mm and a width of 2mm at the upper edge of the metal fixing buckle 1. The "square" hole is used to install the binding strap 2.

[0018] (2) The metal fasteners 1 are welded to the vehicle body by welding, with two metal fasteners 1 welded at each of the top and bottom, and left and right symmetrical positions, arranged as follows: Figure 1 As shown.

[0019] (3) The distance between the lower edge of the upper metal buckle and the upper edge of the lower metal buckle is 587mm, and the distance between the right edge of the left metal buckle and the left edge of the right metal buckle is 432mm. This ensures that after the composite armor piece 4 is installed in the middle of the metal buckle 1, a certain gap is maintained between it and each metal buckle 1, leaving a certain installation allowance for the binding strap 2.

[0020] (4) Fix the composite armor 4 to the middle of the metal buckle 1 with manual assistance. Fix one end of the aramid binding strap 2 with a thickness of 2mm and a width of 27mm to the tensioner 3, and insert the other end through the "square" hole of the upper metal buckle and out through the "square" hole of the lower metal buckle on the symmetrical part. Connect the binding strap 2 to the other end of the tensioner 3. Through the "self-tightening" function of the tensioner 3, the binding strap 2 is kept in a tight state to ensure that the composite armor 4 is tightly connected to the vehicle body.

[0021] (5) According to the following Figure 2 The binding straps are arranged in such a way that the binding straps 2 are installed on the metal fixing buckles 1 that are symmetrically distributed vertically and horizontally via tensioners 3, thereby achieving a tight installation of the composite armor component 4.
