Technical Field

[0001] This utility model relates to the field of radio frequency identification technology, and specifically to an RFID identification back clip. Background Technology

[0002] RFID (Radio Frequency Identification) is a technology that uses radio signals to achieve contactless automatic identification and data transmission. Its core principle is to use electromagnetic waves to transmit information between tags and readers, completing identification and data exchange without physical contact. Currently, RFID modules are attached to terminal devices via clips for portability. However, different terminal devices are used during operation, and these devices vary in size. This necessitates changing the clip after each device change, affecting usability. Therefore, there is a need for a simple RFID identification clip suitable for mounting on terminal devices of different sizes. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a novel RFID identification back clip, which solves the problem that existing technologies are not suitable for adapting to terminal devices of different sizes.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An RFID identification back clip for attaching an RFID component to a terminal device includes a first back clip plate, a second back clip plate, and an RFID component. The second back clip plate is located on the side of the first back clip plate. The first back clip plate has at least one guide groove along its width direction. On the side of the second back clip plate close to the first back clip plate, corresponding to the position of the guide groove, a guide piece is provided. The guide piece extends toward the guide groove and at least partially passes through the guide groove, so that the second back clip plate and the first back clip plate are slidably connected.

[0006] The two opposite sides of the first back clamp are the first side and the second side, respectively. The first side of the first back clamp and the second back clamp together form a receiving area for accommodating the terminal device. The RFID component includes a housing and an RFID part disposed in the housing. The housing is detachably installed on the second side of the first back clamp.

[0007] Furthermore, a tension spring is provided in the guide groove. The end of the guide groove near the second back clamp is a slot. One end of the tension spring is connected to the side wall of the guide groove away from the slot. The end of the guide piece away from the second back clamp passes through the slot and is connected to the other end of the tension spring.

[0008] Furthermore, a pressing edge is provided at the opening of the guide groove.

[0009] Furthermore, the first back clamp extends from the side away from the second back clamp toward the first side to form an extension section, and a fixed fastening part is provided in the extension section; the second back clamp is provided with a movable fastening part on the side away from the first back clamp.

[0010] Furthermore, a plurality of ventilation holes are provided on the first side of the first back clamp, and a vent is provided on the second side of the first back clamp corresponding to the position of the ventilation holes, and the ventilation holes are connected to the vent.

[0011] Furthermore, the diameter of the ventilation hole is larger than the diameter of the air vent.

[0012] Furthermore, the width of the second back clamp is less than 1 / 2 the width of the first back clamp.

[0013] Furthermore, the housing is composed of a bottom shell and an end cap. The bottom shell has multiple screw holes that penetrate itself and extend to the first back plate. Screws are installed in the screw holes. The bottom shell and the first back plate are connected by inserting screws into the screw holes of the bottom shell and the first back plate.

[0014] Furthermore, a battery is provided inside the bottom shell, and the battery is connected to the RFID unit.

[0015] Furthermore, the end cap is provided with a slot along its inner circumference, and the bottom shell is provided with a retaining edge along its outer circumference at one end near the end cap. The retaining edge is inserted into the slot so that the bottom shell and the end cap are engaged. The end cap is provided with a charging part, which is connected to the battery.

[0016] Compared to existing technologies, the advantages of this invention are that, by adopting the above solution, the structure is simple and suitable for mounting terminal devices of different sizes. First, the RFID unit is installed inside the housing, and then the housing is fixed to the second side of the first back clamp with screws. Subsequently, a force is applied to the second back clamp away from the first back clamp, pulling the second back clamp away from the first back clamp along the guide groove, thereby increasing the accommodating space between the first side of the first back clamp and the second back clamp. Then, one side of the terminal device is placed against the fixing fastener of the first back clamp, and then the second back clamp is released, allowing the second back clamp to be pulled back along the guide groove under the action of the tension spring, so that the movable fastener of the second back clamp is fastened to the other side of the terminal device, cooperating with the fixing fastener of the first back clamp to fasten the terminal device, thereby realizing the connection between the terminal device and the back clamp, which has good market application value.

[0025] One embodiment of this utility model is as follows: Figure 1 , 2As shown, the RFID identification back clip is used to attach the RFID component 3 to a terminal device. It includes a first back clip 1, a second back clip 2, and the RFID component 3. The second back clip 2 is located on the side of the first back clip 1. The first back clip 1 is provided with at least one guide groove 16 along its own width direction. On the side of the second back clip 2 close to the first back clip 1, corresponding to the position of the guide groove 16, a guide piece 21 is provided. The guide piece 21 extends toward the guide groove 16 and is at least partially inserted into the guide groove 16 so that the second back clip 2 and the first back clip 1 are slidably connected.

[0026] The two opposite sides of the first back clamp 1 are the first side 11 and the second side 12, respectively. The first side 11 of the first back clamp 1 and the second back clamp 2 together form a receiving area for accommodating the terminal device. The RFID component 3 includes a housing 31 and an RFID part 32 disposed in the housing 31. The housing 31 is detachably installed on the second side 12 of the first back clamp 1.

[0027] The RFID identification back clip of this solution is suitable for mounting terminal devices of different sizes. First, the RFID unit 32 is installed in the housing 31, and then the housing 31 is fixed to the second side 12 of the first back clip 1 with screws. Then, a force away from the first back clip 1 is applied to the second back clip 2, pulling the second back clip 2 away from the first back clip 1 along the guide groove 16, so as to increase the accommodating space between the first side 11 of the first back clip 1 and the second back clip 2. Then, one side of the terminal device is placed against the fixing fastening part 13 of the first back clip 1, and then the second back clip 2 is released, so that the second back clip 2 is pulled back along the guide groove 16 under the action of the tension spring 17, so that the movable fastening part 22 of the second back clip 2 is fastened to the other side of the terminal device, so as to cooperate with the fixing fastening part 13 of the first back clip 1 to fasten the terminal device, thereby realizing the connection between the terminal device and the back clip.

[0028] In this embodiment, as Figure 3 As shown, a tension spring 17 is provided in the guide groove 16. The end of the guide groove 16 near the second back clamp 2 is a groove. One end of the tension spring 17 is connected to the side wall of the guide groove 16 away from the groove. The end of the guide piece 21 away from the second back clamp 2 passes through the groove and is connected to the other end of the tension spring 17.

[0029] Specifically, the second back clamp 2 is located to the left of the first back clamp 1. The guide groove 16 is horizontally arranged on the first back clamp 1, with the left end being the groove opening. A guide piece 21 is arranged on the right side of the second back clamp 2. The guide piece 21 passes through the groove opening and is slidably arranged in the guide groove 16. By pulling the second back clamp 2, the distance between the second back clamp 2 and the first back clamp 1 is adjusted, thereby adjusting the accommodating area space between the first side 11 of the first back clamp 1 and the second back clamp 2.

[0030] In this embodiment, as Figure 3 As shown, the guide groove 16 has a pressing edge 18 at the groove opening.

[0031] Specifically, both ends of the guide groove 16 extend inward to form pressing edges 18 to prevent the second back clamp 2 from moving excessively, so that the guide piece 21 can be completely pulled out of the guide groove 16.

[0032] In this embodiment, as Figure 1 As shown, the first back clamp 1 extends from the side away from the second back clamp 2 toward the first side 11 to form an extension section, and a fixed fastening part 13 is provided in the extension section; the second back clamp 2 is provided with a movable fastening part 22 on the side away from the first back clamp 1.

[0033] Specifically, the right side of the first back clamp 1 extends forward to form an extension section, and a fixed fastening part 13 is provided at the front end of the extension section. The left side of the second back clamp 2 extends forward and a movable fastening part 22 is provided. The tension spring 17 applies a force to the second back clamp 2 to move it to the right, so that the movable fastening part 22 cooperates with the fixed fastening part 13 of the first back clamp 1 to fasten the terminal device, thereby realizing the connection between the terminal device and the back clamp.

[0034] In this embodiment, as Figure 1 , 2 As shown, a plurality of ventilation holes 14 are provided on the first side 11 of the first back clamp plate 1, and ventilation holes 15 are provided on the second side 12 of the first back clamp plate 1 corresponding to the positions of the ventilation holes 14, and the ventilation holes 14 and the ventilation holes 15 are connected.

[0035] Specifically, the first back clamp 1 is divided into a ventilation part and an installation part. The RFID component 3 is installed on the installation part of the first back clamp 1. The ventilation hole 14 and the vent hole 15 form the ventilation part of the first back clamp 1. The ventilation hole 14 and the vent hole 15 allow air to circulate on both sides of the first back clamp 1. When the back clamp is fitted onto the terminal device, the heat generated during device operation can be quickly conducted.

[0036] In this embodiment, as Figure 1 , 2 As shown, the diameter of the ventilation hole 14 is larger than the diameter of the air vent 15.

[0037] Specifically, multiple ventilation holes 14 form a honeycomb pattern on the first side 11 of the first back plate 1, and one ventilation hole 14 and the air vent 15 form a heat dissipation hole. The diameter of the heat dissipation hole gradually decreases from the first side 11 to the second side 12, so that a pressure difference is formed on both sides of the first back plate 1, which allows the heat generated during the operation of the terminal device to be quickly conducted.

[0038] In this embodiment, as Figure 1 As shown, the width of the second back clamp 2 is less than 1 / 2 of the width of the first back clamp 1.

[0039] Specifically, the width of the first backplate 1 is 7cm, and the width of the second backplate 2 is 2cm. The first backplate 1 is the main bonding part, and most of the back of the terminal device is attached to the first backplate 1 to facilitate heat dissipation.

[0040] In this embodiment, as Figure 4 As shown, the housing 31 is composed of a bottom shell 33 and an end cap 34. The bottom shell 33 is provided with a plurality of screw holes 36 that penetrate itself and extend to the first back clamp plate 1. Screws are provided in the screw holes 36. The bottom shell 33 and the first back clamp plate 1 are connected by inserting screws into the screw holes 36 of the bottom shell 33 and the first back clamp plate 1.

[0041] Specifically, each of the four corners of the bottom shell 33 is provided with a post, and a through screw hole 36 is provided on the post. The screw hole 36 on the second side 12 of the first back clamp plate 1 is a blind hole. First, the RFID part 32 is fixed in the corresponding position inside the bottom shell 33. Screws are screwed into the screw holes 36 of the bottom shell 33 and the first back clamp plate 1 to connect the bottom shell 33 and the first back clamp plate 1. Then, the end cap 34 is fastened to the bottom shell 33 to realize the detachable installation of the RFID component 3 and the first back clamp plate 1.

[0042] In this embodiment, as Figure 4 As shown, a battery 35 is provided inside the bottom shell 33, and the battery 35 is connected to the RFID unit 32.

[0043] Specifically, the battery 35 is located at the lower part of the bottom shell 33, and the RFID unit 32 is located at the upper part of the bottom shell 33. The RFID component 3 has its own battery 35 and actively transmits signals. It is integrated into our terminal devices of different sizes and models through the RFID back clip composed of the first back clip 1 and the second back clip 2. It supports 902-928MHZ / 865-868MHZ, transmits electromagnetic waves and receives tag responses, can read multiple tags at the same time, can penetrate non-metallic materials (such as cardboard boxes and liquids), supports harsh environments (high temperature, dust, humidity), and supports multiple read and write operations.

[0044] In this embodiment, as Figure 4 As shown, the end cap 34 is provided with a slot along its inner circumference, and the bottom shell 33 is provided with a retaining edge along its outer circumference at one end near the end cap 34. The retaining edge is inserted into the slot so that the bottom shell 33 is engaged with the end cap 34. The end cap 34 is provided with a charging part 37, which is connected to the battery 35.

[0045] Specifically, the charging unit 37 has metal contacts and is connected to the charger by magnetic attraction to charge the battery 35.

[0046] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this utility model.
