Description

Technical Field

[0001] This utility model relates to the field of GPS positioning technology, specifically to a multi-layered composite anti-vandalism protection structure for vehicle positioning terminals. Background Technology

[0002] The vehicle positioning terminal, also known as the vehicle-mounted terminal or GPS / BeiDou terminal, is a special device that uses satellite signals to achieve real-time vehicle positioning. It consists of three parts: the vehicle-mounted monitoring terminal, the communication network, and the dispatch and monitoring center. [3] The vehicle-mounted monitoring terminal is responsible for calculating the positioning coordinates based on the received GPS / BeiDou satellite signals and sending positioning information, status information, and control commands through the communication network. The communication network includes GSM / GPRS / CDMA base stations and the Internet to realize data interaction between the vehicle and the dispatch and monitoring center. As the communication core of the information system, the dispatch and monitoring center undertakes the functions of information exchange, content classification, record storage, and command forwarding.

[0003] The existing technology has the following problems: Among existing vehicle tracking terminals, some lack protective structures, their outer surfaces are directly exposed, and they are directly installed on the vehicle; others are protected by ABS plastic shells. When a vehicle tracking terminal is discovered by others, it may be forcibly removed, which can easily damage not only the terminal itself but also the ABS plastic shell. Once the vehicle tracking terminal is damaged, it becomes unusable, and it also hinders the proper installation and positioning of the terminal relative to the protective structure. Therefore, we need a multi-layered, composite, vandal-resistant protection structure for vehicle-mounted positioning terminals to solve the above problems. Utility Model Content

The fixing component includes a fixing block and a connecting block, the surface of which penetrates through the interior of the buffer layer, and the surface of which is fixedly connected to the surface of the metal puncture-resistant layer.

[0007] A further improvement of this utility model is that the hardware protective layer, the anti-drilling protective layer, the metal anti-puncture layer, and the buffer layer are connected by an adhesive, and the outer surfaces of the hardware protective layer, the anti-drilling protective layer, the metal anti-puncture layer, and the buffer layer are all provided with a plurality of through holes in a ring array, and the plurality of through holes correspond to each other.

[0008] A further improvement of the present invention is that the second fixing block and the first fixing block are arc-shaped, and an arc-shaped groove is provided on the inner side of the second fixing block, and the inner wall of the arc-shaped groove is connected to the inner and outer sides on the left side.

[0009] A further improvement of the present invention is that: a groove is provided on the surface of the connecting block, a rubber block is fixedly connected to the upper part of the inner wall of the groove, an installation plate is fixedly connected to the lower surface of the rubber block, a T-shaped groove is provided on the lower surface of the installation plate, the inner and outer sides of the inner wall of the T-shaped groove are connected, a T-shaped block is slidably connected inside the T-shaped groove, and a limit plate is fixedly connected to the lower part of the outer surface of the T-shaped block.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides a multi-layer composite anti-vandalism protection structure for vehicle-mounted positioning terminals. The buffer layer uses high-density foam to cushion impacts. The metal puncture-resistant layer uses a 2mm thick high-strength metal plate, which mainly resists punctures from sharp objects due to its high strength. The anti-drilling protective layer mainly prevents cutting by drill bits. The hardware protection layer mainly uses adhesive to firmly fix the hardware inside the structure, preventing severe vibrations or deformations from external damage. Through the cooperation of these structures, the protection structure can effectively protect the vehicle-mounted positioning terminal, enhancing its protective performance and making it less prone to damage.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example 1: As Figures 1 to 5As shown, this utility model provides a multi-layered composite anti-vandalism protection structure for a vehicle-mounted positioning terminal, including a protective structure 1. The protective structure 1 is the core component that protects the vehicle-mounted positioning terminal 5. A hardware protective layer 11 is provided on the outer surface of the protective structure 1. The hardware protective layer 11 mainly uses an adhesive to completely wrap around the vehicle-mounted positioning terminal 5 and firmly fix it inside the structure to prevent severe vibration or deformation caused by external damage. In use, the vehicle-mounted positioning terminal 5 can be placed in the hardware protective layer 11, and the adhesive is sprayed onto the lower surface of the vehicle-mounted positioning terminal 5 and cooled and solidified to achieve complete wrapping of the vehicle-mounted positioning terminal 5. An anti-drilling protective layer 12 is provided on the outer surface of the hardware protective layer 11. When an external force attempts to damage the terminal by drilling, the anti-drilling protective layer 12 can effectively resist the cutting of drilling tools, delay or even stop the drilling process, and protect the internal terminal from being drilled through. The outer surface of the anti-drilling protective layer 12 is provided with a metal puncture-resistant layer 13, which is made of high-strength metal material and has excellent puncture resistance. It can resist the puncture of sharp objects and further enhance the protective structure's resistance to damage. A buffer layer 14 is provided on the outer surface of the metal puncture-resistant layer 13, which plays a buffering role during the hammer impact process. In addition, the adhesive material in the hardware protective layer 11 is one of epoxy resin adhesive, polyurethane adhesive or acrylic adhesive; the anti-drilling protective layer 12 is mainly made of high-hardness ceramics such as alumina and silicon carbide, combined with metal matrix composites such as tungsten alloys and titanium alloys or fiber-reinforced composites such as carbon fiber and aramid fiber to achieve synergistic protection; the metal puncture-resistant layer 13 is made of stainless steel plate; and the buffer layer 14 is made of high-density foam.

[0017] The hardware protective layer 11, the anti-drilling protective layer 12, the metal puncture-resistant layer 13, and the buffer layer 14 are connected by adhesive to ensure that each layer fits tightly and forms an integral protective structure, avoiding protection failure due to separation between layers. The outer surfaces of the hardware protective layer 11, the anti-drilling protective layer 12, the metal puncture-resistant layer 13, and the buffer layer 14 are all provided with a number of corresponding through holes 15 in a ring array. The design of the through holes 15 facilitates the signal transmission of the wireless GPS, so as to prevent the protection structure 1 and the base 2 from being in a closed environment, which may cause the signal to be blocked. Example 2: Figures 1 to 5 As shown, a base 2 made of steel is provided below the outer surface of the protective structure 1. A magnetic block can be installed and fixed at the bottom for easy connection with the vehicle. Fixing blocks 3 and fixing components 4 are fixedly connected to the front and rear of the upper surface of the base 2. Together, they firmly fix the protective structure 1 in the base 2. In addition, the outer surface of the fixing block 3 penetrates the interior of the buffer layer 14 and is fixed to the surface of the metal puncture-resistant layer 13. The fixing component 4 includes a fixing block 41 and a connecting block 42. The surface of the connecting block 42 extends through the interior of the buffer layer 14. The surface of the connecting block 42 is fixedly connected to the surface of the metal puncture-resistant layer 13. The design of the connecting block 42 facilitates the installation and connection with the fixing block 41. A groove is provided on the surface of the connecting block 42. A rubber block 43 is fixedly connected to the upper part of the inner wall of the groove. The rubber block 43 has a certain elasticity, which facilitates the movement of the subsequent structural limiting plate 45. A mounting plate 44 is fixedly connected to the lower surface of the rubber block 43. A T-shaped groove with internal and external communication is opened on the rear side of the lower surface of the mounting plate 44. A T-shaped block 46 is slidably connected inside the T-shaped groove. A limiting plate 45 is fixedly connected to the lower surface of the outer surface of the T-shaped block 46. The cooperation between the T-shaped groove and the T-shaped block 46 allows the limiting plate 45 to slide along the mounting plate 44, which facilitates the adjustment of the position of the limiting plate 45. Fixed block 41 is arc-shaped, with an arc-shaped groove on its inner side. The inner wall of the arc-shaped groove is open to the outside and inside on the left side. The arc-shaped groove facilitates the accommodation of the structure in the connecting block 42. Rubber block 47 is fixedly connected to the lower right side of the inner wall of the arc-shaped groove in fixed block 41. The rubber block 47 serves to elevate the connecting block 42 and prevent its lower surface from being suspended. A blocking block 48 is fixedly connected to the lower side of the inner wall of the arc-shaped groove in fixed block 41 near the rubber block 47. The blocking block 48 is in the shape of a right triangle, and its outer surface corresponds to the outer surface of the limiting plate 45. The blocking block 48 limits the positioning of the limiting plate 45. In addition, there are patterns between the rubber block 47 and the blocking block 48, and there are also patterns on the lower surface of the limiting plate 45. When the limiting plate 45 limits the blocking block 48, the two patterns come into contact, increasing the friction and preventing the limiting plate 45 from sliding easily. Example 3: Figures 1 to 5 As shown, a connecting shaft 31 is fixedly connected to the rear side of the upper surface of the base 2. The outer surface of the connecting shaft 31 is movably connected through the interior of the fixing block 3. The fixing block 3 is in contact with the base 2. The connecting shaft 31 provides a fulcrum for the rotation of the fixing block 3, allowing the fixing block 3 to rotate around the connecting shaft 31. An anti-detachment block is fixedly connected to the upper end of the connecting shaft 31 to prevent the fixing block 3 from detaching from the connecting shaft 31, ensuring the rotational stability of the fixing block 3. The fixing block 3 is also in an arc shape. Working principle: Through the coordinated operation of the hardware protection layer 11, the anti-drilling protection layer 12, the metal anti-puncture layer 13 and the buffer layer 14, the vehicle positioning terminal 5 has the characteristics of multi-layer protection against damage, which enhances the protection performance and makes the vehicle positioning terminal 5 less likely to be damaged.

[0018] In use, the vehicle-mounted positioning terminal 5 is placed into the colloid within the hardware protective layer 11, and then the protective structure 1 is rotated. When rotated to the appropriate position, the connecting block 42 enters the interior of the second fixing block 41, and the limiting plate 45 contacts the inclined surface of the blocking block 48. The worker continues to rotate the protective structure 1, causing the limiting plate 45 and the mounting plate 44 to move upwards, compressing the first rubber block 43 and causing it to contract. When the second rubber block 47 contacts the connecting block 42, the limiting plate 45 is positioned between the second rubber block 47 and the blocking block 48. Subsequently, under the elastic action of the first rubber block 43, it resets, allowing the limiting plate 45 to enter between the second rubber block 47 and the blocking block 48, and under the action of the blocking block 48, it performs blocking and limiting, completing the installation of the vehicle-mounted positioning terminal 5.

[0019] When disassembly is required, workers can use tools such as screwdrivers to insert into the interior of the fixing block 41, contact one side of the limiting plate 45 and apply force to move the limiting plate 45 inside the mounting plate 44. After moving to the appropriate position, the limiting plate 45 separates from the blocking block 48, and the worker can directly rotate the protective structure 1 to move the connecting block 42 out of the fixing block 41, facilitating disassembly. The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
