Description

Technical Field

[0001] This utility model belongs to the field of equipment cabinet technology, and specifically relates to a vehicle-mounted RFID equipment cabinet with remote inventory function. Background Technology

[0002] The vehicle-mounted RFID equipment cabinet primarily utilizes Radio Frequency Identification (RFID) technology. This technology automatically identifies target objects and acquires relevant data through radio frequency signals, requiring no manual intervention. Inside the cabinet, each piece of equipment is affixed with an RFID tag, which stores a unique identifier and detailed information such as equipment name, model, category, and entry time. An RFID reader is installed inside the cabinet, emitting radio frequency signals. When equipment with an RFID tag enters the reader's range, the tag is activated, transmitting the stored information back to the reader via radio frequency. Upon receiving the signal, the reader decodes the data and transmits it to the cabinet's control system. The control system analyzes and processes this data to achieve precise equipment positioning, status monitoring, and entry / exit recording. For example, when equipment is placed in the cabinet, the RFID reader immediately identifies the tag information and stores it in the system database, recording the entry time and location. Conversely, when equipment is removed, the reader quickly detects this, updates the equipment's status in the system to "out of storage," and records the time of removal.

[0003] However, existing vehicle-mounted RFID equipment cabinets lack environmental adaptability. Vehicle environments are prone to vibration; for example, road bumps can cause vibration acceleration up to 5g, leading to reading errors or tag detachment. Furthermore, the tag's lifespan is typically less than 6 months. Additionally, traditional RFID readers suffer from outdated anti-collision algorithms, resulting in a missed reading rate as high as 15%, failing to meet the requirements for accurate inventory counting. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a vehicle-mounted RFID equipment cabinet with remote inventory function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vehicle-mounted RFID equipment cabinet with remote inventory function, comprising a cabinet body, the cabinet body including a support base, a base sleeved on the bottom of the support base, a hydraulic damper one and a hydraulic damper two respectively provided inside the base, mounting parts one rotatably connected to both ends of the hydraulic damper one and the hydraulic damper two, mounting parts two provided on one side of the mounting parts one, mounting parts three fixedly connected to the inside of the support base on the top of one side of the mounting parts two, a connecting rod rotatably connected between the mounting parts three and the mounting parts two, a horizontal plate fixedly installed on one side of the mounting parts three, and a support spring fixedly installed at the bottom of the horizontal plate.

[0006] Preferably, the support base is fixedly connected to the main body of the equipment cabinet, and the bottom of the base is fixedly equipped with symmetrical support feet.

[0007] Preferably, a sleeve ring is fixedly sleeved on both the surface and the output end of the hydraulic damper, and a load-bearing spring sleeved on the surface of the hydraulic damper is fixedly connected between the two sleeve rings.

[0008] Preferably, a connecting ring 2 is fixedly sleeved on both the surface and the output end of the hydraulic damper 2, and a bearing spring 2 sleeved on the surface of the hydraulic damper 2 is fixedly connected between the two connecting rings 2.

[0009] Preferably, the bottoms of mounting component one and mounting component two are fixedly mounted with a movable plate, the bottom of the movable plate is fixedly mounted with a slider one, and the base has a groove one for sliding with the slider one.

[0010] Preferably, sliders are fixedly installed on both sides of the base, and the inside of the support base is provided with a groove for sliding with sliders.

[0011] Preferably, both ends of the base are fixedly installed with sliders three, and the inside of the support base is provided with a sliding groove three for sliding with the sliders three.

[0012] Preferably, a fixing ring that is fixedly connected to the base is fixedly installed at the bottom of the support spring, and an inner guide rod located inside the support spring is fixedly installed at the top of the fixing ring.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. When encountering shaking or bumps in a vehicle-mounted environment, the hydraulic damper one and hydraulic damper two effectively absorb and dissipate vibration energy through the compression and flow of internal hydraulic oil. During this process, the load-bearing springs one and two form a synergistic buffering structure with the hydraulic dampers one and two, respectively. The elastic deformation of the springs absorbs the instantaneous impact before the hydraulic dampers, and then the hydraulic dampers one and two suppress the reciprocating vibration of the load-bearing springs one and two through viscous resistance, forming a dual shock absorption mechanism of "buffering first, then energy dissipation," thereby improving the adaptability of this equipment cabinet to the environment.

[0015] 2. In this invention, when vehicle vibration causes displacement of mounting component one and the moving plate, hydraulic dampers one and two will drive mounting component two and the connecting rod to adjust the height of mounting component three. This linkage process, through precise control of the hydraulic system, allows the support seat to dynamically adapt to the vibration amplitude at the top of the base. When the vibration tends to stabilize, the hydraulic oil slowly flows back, and the support seat returns to its initial position under the action of the spring force, ensuring that the equipment always remains horizontal and stable. This design reduces the peak acceleration of vehicle vibration through the nonlinear dynamic response of the hydraulic dampers and bearing springs one and two. At the same time, through the linkage adjustment of mounting component two, mounting component three, and the connecting rod, the vertical displacement of the support seat is controlled, significantly improving the stability and reliability of the vehicle-mounted equipment under complex road conditions.

[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0027] refer to Figures 1-8 A vehicle-mounted RFID equipment cabinet with remote inventory function includes a cabinet body 1, which includes a support base 101. A base 2 is sleeved on the bottom of the support base 101. A hydraulic damper 3 and a hydraulic damper 4 are respectively provided inside the base 2. Mounting parts 5 are rotatably connected to both ends of the hydraulic damper 3 and the hydraulic damper 4. Mounting part 7 is provided on one side of mounting part 5. Mounting part 9 is fixedly connected to the inside of the support base 101 on the top of one side of mounting part 7. A connecting rod 8 is rotatably connected between mounting part 9 and mounting part 7. A horizontal plate 10 is fixedly installed on one side of mounting part 9. A support spring 13 is fixedly installed at the bottom of the horizontal plate 10. When encountering shaking or bumps in a vehicle-mounted scenario, the hydraulic damper 3 and the hydraulic damper 4 effectively absorb and dissipate vibration energy through the compression and flow of internal hydraulic oil. During this process, load-bearing spring 302 and load-bearing spring 402 form a synergistic buffer structure with hydraulic damper 3 and hydraulic damper 4, respectively. The elastic deformation of the springs absorbs the instantaneous impact before the hydraulic damper 4. Subsequently, hydraulic damper 3 and hydraulic damper 4 suppress the reciprocating vibration of load-bearing spring 302 and load-bearing spring 402 through viscous resistance, forming a dual shock absorption mechanism of "buffering first and then dissipating energy", thereby improving the adaptability of this equipment cabinet to the environment.

[0028] The support base 101 is fixedly connected to the equipment cabinet body 1. The bottom of the base 2 is fixedly equipped with symmetrical support feet 201. The support base 101 supports and fixes the equipment cabinet body 1, and the support feet 201 cooperate with the base 2 for support.

[0029] Both the surface and output end of the hydraulic damper 3 are fixedly fitted with a sleeve ring 301. A load-bearing spring 302 fitted on the surface of the hydraulic damper 3 is fixedly connected between the two sleeve rings 301. The sleeve rings 301 cooperate with the load-bearing spring 302 for support and fixation. When the load-bearing spring 302 and the hydraulic damper 3 cooperate with each other, a buffering effect is achieved. The hydraulic damper 3 prevents the load-bearing spring 302 from rebounding rapidly after contraction.

[0030] Both the surface and output end of the hydraulic damper 4 are fixedly fitted with a sleeve ring 401. A load-bearing spring 402 fitted on the surface of the hydraulic damper 4 is fixedly connected between the two sleeve rings 401. The sleeve rings 401 cooperate with the load-bearing spring 402 for support and fixation. When the load-bearing spring 402 and the hydraulic damper 4 cooperate with each other, a buffering effect is achieved. The hydraulic damper 4 prevents the load-bearing spring 402 from rebounding rapidly after contraction.

[0031] The bottoms of mounting components 5 and 7 are fixedly mounted with a movable plate 6. A slider 601 is fixedly mounted on the bottom of the movable plate 6. The base 2 has a groove 602 inside that slides with the slider 601. Mounting component 5 will be used to support hydraulic dampers 3 and 4 respectively. During the contraction and extension of hydraulic dampers 3 and 4, the sliding connection between slider 601 and groove 602 will guide the movement of the movable plate 6.

[0032] Slider 2 14 is fixedly installed on both sides of the base 2. The support base 101 has a slide groove 2 15 inside for sliding with slider 2 14. The sliding connection between slider 2 14 and slide groove 2 15 will guide the base 2 to move inside the support base 101.

[0033] Both ends of the base 2 are fixedly installed with sliders 3 16. The inside of the support base 101 is provided with a sliding groove 3 17 for sliding with sliders 3 16. The sliding connection between sliders 3 16 and sliding groove 3 17 will guide the base 2 to move inside the support base 101.

[0034] A fixing ring 11, which is fixedly connected to the base 2, is fixedly installed at the bottom of the support spring 13. An inner guide rod 12 located inside the support spring 13 is fixedly installed at the top of the fixing ring 11. The fixing ring 11 is installed in conjunction with the support spring 13. During the contraction and extension of the support spring 13, the inner guide rod 12 will guide it.

[0035] Brief Description of Usage: When encountering shaking or bumps in a vehicle environment, the hydraulic dampers 3 and 4 effectively absorb and dissipate vibration energy through the compression and flow of internal hydraulic oil. During this process, the load-bearing springs 302 and 402 form a synergistic buffer structure with the hydraulic dampers 3 and 4, respectively. The elastic deformation of the springs absorbs the instantaneous impact before the hydraulic damper 4, and then the hydraulic dampers 3 and 4 suppress the reciprocating vibration of the load-bearing springs 302 and 402 through viscous resistance.

[0036] When vehicle vibration causes displacement of mounting component 5 and moving plate 6, hydraulic dampers 3 and 4 drive mounting component 7 and connecting rod 8 to adjust the height of mounting component 9. This linkage process, through precise control of the hydraulic system, allows support 101 to dynamically adapt to the vibration amplitude at the top of base 2. When the vibration amplitude is large, the internal pressure of hydraulic dampers 3 and 4 increases, pushing mounting component 7 to move laterally and causing mounting component 9 to move longitudinally. The distance between support 101 and base 2 is reduced or increased through connecting rod 8 to disperse the impact force. When the vibration tends to stabilize, the hydraulic oil slowly flows back, and support 101 returns to its initial position under the action of spring force, ensuring that the equipment always remains horizontal and stable. This design reduces the peak acceleration of vehicle vibration through the nonlinear dynamic response of hydraulic damper 4 and load-bearing springs 302 and 402, while controlling the vertical displacement of support 101 through the linkage adjustment of mounting component 7, mounting component 9, and connecting rod 8. Meanwhile, the support spring 13 will retract and extend in response to changes in position between the base 2 and the support 101, providing support for the support 101 and the base 2 while also facilitating their movement. Simultaneously, the sliding of slider 2 14 within slide groove 2 15 and slider 3 16 within slide groove 3 17 will guide changes in position between the support 101 and the base 2, ensuring the safe use of the equipment cabinet.
