Abstract
Description
Technical Field
[0001] This utility model relates to the field of RFID temperature measurement technology, and in particular to a charging pile temperature measurement device based on RFID radio frequency technology. Background Technology
[0002] The RFID temperature measurement device for charging piles mainly consists of RFID temperature tags and RFID readers. The RFID temperature tag integrates a miniature temperature sensor chip and an RFID antenna. It does not require battery power. When the RFID reader transmits a radio frequency signal, the temperature tag obtains energy through antenna coupling, which activates the internal temperature sensor to collect temperature data. The temperature sensor encodes the collected temperature data and reflects it back to the RFID reader through backscatter modulation. The reader then transmits the received temperature data to an edge gateway or cloud platform for processing and analysis through interfaces such as RS485 / Ethernet / 4G / 5G.
[0003] Chinese Patent Publication No. CN223051730U, published on 20250701, discloses a passive ultra-high frequency RFID temperature measurement tag, including a locking and fixing mechanism, a connecting component, a fixing plate, a placement plate, a transparent protective plate, and a body. The locking and fixing mechanism is disposed on both sides of the transparent protective plate, the connecting component is disposed on both sides of the placement plate, the fixing plate is fixedly connected to the bottom of the placement plate, the placement plate is locked to the bottom of the transparent protective plate, and the body is disposed on the top of the placement plate.
[0004] Existing charging pile temperature measurement devices based on RFID radio frequency technology mainly consist of RFID temperature tags and RFID readers. However, RFID temperature tags are mostly directly bonded to the heating parts with 3M high-temperature adhesive. High-temperature adhesive is greatly affected by temperature and external humidity, and RFID temperature tags are prone to loosening or even falling off. Therefore, there is an urgent need to propose a corresponding charging pile temperature measurement device based on RFID radio frequency technology to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a charging pile temperature measurement device based on RFID radio frequency technology in order to solve the above problems.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A charging pile temperature measurement device based on RFID radio frequency technology includes an RFID reader, an RFID temperature tag, and a heat-conducting plate. The heat-conducting plate is fixedly connected to the heat-generating part of the charging pile through a connecting component. A frame is fixedly connected to the outer wall of the heat-conducting plate. The RFID temperature tag is snapped between the frame and the heat-conducting plate. A pressure strip and an elastic telescopic component for maintaining the position of the pressure strip are provided on the outside of the heat-conducting plate. The pressure strip abuts against the outside of the RFID temperature tag.
[0008] Preferably, the connecting assembly includes a mounting plate fixedly connected to the outer wall of the heat-conducting plate, and a locking rod is provided inside the mounting plate.
[0009] Preferably, the pressure strip is provided with an extension section, and an abutment strip that abuts against the outer wall of the extension section is fixedly connected to the outer wall of the locking rod.
[0010] Preferably, the elastic telescopic component includes a sleeve fixedly connected to the outer wall of the heat-conducting plate, and a spring is fixedly connected between the inner wall of the sleeve and the pressure strip.
[0011] Preferably, an outer frame is fixedly connected to the outside of the mounting plate, and multiple sets of slots are connected between the outer frame, the sleeve and the outer frame, and the pressure strip slides into the multiple sets of slots.
[0012] Preferably, notches are provided on both sides of the vertical end of the card frame.
[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0014] 1. In this application, the heat-conducting plate is fixed to the outside of the heating component by the cooperation of the locking rod and the mounting plate. The RFID temperature tag is placed in the frame and made to fit the RFID temperature tag against the heat-conducting plate. Then, the pressure strip is released and the spring pulls the pressure strip to press it against the outside of the RFID temperature tag, thereby realizing the installation of the RFID temperature tag. The stability of the outside of the heating component can be normally transmitted to the RFID temperature tag through the heat-conducting plate. At the same time, the fixing method of the spring and the pressure strip ensures the stability of the RFID temperature tag position. After pulling the pressure strip to a suitable length, the RFID temperature tag can be easily removed and replaced.
[0015] 2. In this application, the extended section of the pressure strip can cover the outside of the locking rod. When the pressure strip abuts against the outside of the RFID temperature tag under the action of the spring, the abutting strip on the outer wall of the pressure strip will press against the outside of the locking rod. The friction generated between the abutting strip and the locking rod can limit the axial loosening of the locking rod, thereby improving the stability of the charging pile temperature measurement device based on RFID radio frequency technology.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 This utility model provides a technical solution:
[0024] A charging pile temperature measurement device based on RFID radio frequency technology includes an RFID reader / writer 1, an RFID temperature tag 2, and a heat-conducting plate 3. The heat-conducting plate 3 is fixedly connected to the heat-generating part of the charging pile through a connecting component. A frame 5 is fixedly connected to the outer wall of the heat-conducting plate 3. The RFID temperature tag 2 is snapped between the frame 5 and the heat-conducting plate 3. A pressure strip 9 and an elastic telescopic component for maintaining the position of the pressure strip 9 are provided on the outer side of the heat-conducting plate 3. The pressure strip 9 abuts against the outer side of the RFID temperature tag 2.
[0025] The heat-conducting plate 3 is fixed to the outside of the heating component by the cooperation of the locking rod 8 and the mounting plate 4. The RFID temperature tag 2 is placed in the frame 5 and made to fit the heat-conducting plate 3. Then, the pressure strip 9 is released and the spring 10 pulls the pressure strip 9 to press it against the outside of the RFID temperature tag 2, thus realizing the installation of the RFID temperature tag 2. The stability of the outside of the heating component can be normally transmitted to the RFID temperature tag 2 through the heat-conducting plate 3. At the same time, the fixing method of the spring 10 and the pressure strip 9 ensures the stability of the position of the RFID temperature tag 2. After pulling the pressure strip 9 to a suitable length, the RFID temperature tag 2 can be easily disassembled and replaced.
[0026] Specifically, such as Figure 2 and Figure 4 As shown, the connecting assembly includes a mounting plate 4 fixedly connected to the outer wall of the heat-conducting plate 3. A locking rod 8 is inserted inside the mounting plate 4. The heat-conducting plate 3 is fixed to the outside of the heating component by the cooperation of the locking rod 8 and the mounting plate 4. The pressure strip 9 is provided with an extension section. An abutment strip 11 that abuts against the outer wall of the locking rod 8 is fixedly connected to the outer wall of the extension section. The extension section of the pressure strip 9 can cover the outside of the locking rod 8. When the pressure strip 9 abuts against the outside of the RFID temperature tag 2 under the action of the spring 10, the abutment strip 11 on the outer wall of the pressure strip 9 will press against the outside of the locking rod 8. The friction generated between the abutment strip 11 and the locking rod 8 can limit the axial loosening of the locking rod 8, thereby improving the stability of the charging pile temperature measurement device based on RFID radio frequency technology.
[0027] Specifically, such as Figure 2 and Figure 3 As shown, the elastic telescopic assembly includes a sleeve 7 fixedly connected to the outer wall of the heat-conducting plate 3. A spring 10 is fixedly connected between the inner wall of the sleeve 7 and the pressure strip 9 to maintain the engagement state of the pressure strip 9 with the RFID temperature tag 2 and the locking rod 8. An outer frame 6 is fixedly connected to the outer side of the mounting plate 4. Multiple sets of slots are opened between the outer frame 6, the sleeve 7 and the outer frame 6. The pressure strip 9 slides in the multiple sets of slots to further maintain the position of the pressure strip 9. Notches are opened on both sides of the vertical end of the frame 5 to facilitate the placement and removal of the RFID temperature tag 2.
[0028] Working principle: The heat-conducting plate 3 is fixed to the outside of the heating component by the cooperation of the locking rod 8 and the mounting plate 4. The RFID temperature tag 2 is placed in the frame 5 and made to fit the RFID temperature tag 2 against the heat-conducting plate 3. Then, the pressure strip 9 is released, and the spring 10 pulls the pressure strip 9 to press it against the outside of the RFID temperature tag 2, thus realizing the installation of the RFID temperature tag 2. The stability of the outside of the heating component can be normally transmitted to the RFID temperature tag 2 through the heat-conducting plate 3. At the same time, the fixing method of the spring 10 and the pressure strip 9 ensures the stability of the position of the RFID temperature tag 2. After pulling the pressure strip 9 to a suitable length, the RFID temperature tag 2 can be easily disassembled and replaced. The extension of the pressure strip 9 can cover the outside of the locking rod 8. When the pressure strip 9 abuts against the outside of the RFID temperature tag 2 under the action of the spring 10, the abutment strip 11 on the outer wall of the pressure strip 9 will press against the outside of the locking rod 8. The friction generated between the abutment strip 11 and the locking rod 8 can limit the axial loosening of the locking rod 8, thereby improving the stability of the charging pile temperature measurement device based on RFID radio frequency technology.
