Description

Technical Field

[0001] This utility model relates to the field of RFID tag technology, specifically to an RFID tag. Background Technology

[0002] RFID tags are automatic identification devices based on radio frequency identification technology, which use radio waves to achieve contactless data transmission and target object identification.

[0003] Currently, RFID tags are used in various products, such as access control cards with RFID tags. According to the publication number of the existing patent, CN221595669U, an RFID tag fixing structure is provided. In this patent, in order to prevent the RFID tag from failing due to water ingress, corresponding first rubber strips and second rubber strips are respectively set on the top cover and the bottom shell. The first rubber strips and the second rubber strips can form a waterproof structure, which can effectively prevent water from entering the shell.

[0004] However, the upper surface of the bottom shell has a groove for accommodating the first rubber strip. When installing the RFID tag access card, the first rubber strip needs to be embedded into the groove first. However, given the small size of the RFID tag access card, during the process of embedding the first rubber strip, the staff needs to use their fingernails or sharp tools to embed a portion of the first rubber strip into the groove. In addition, to ensure the integrity of the embedding, pressure needs to be applied along the path of the groove to fully embed the first rubber strip into the groove. Therefore, there is an inconvenience in installation. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an RFID tag to solve the technical problem of inconvenient installation of existing RFID tag fixing structures in the background art.

[0006] The present invention provides an RFID tag, including an upper cover and a lower shell that interlock with each other, and a sealing gasket and a support step with a receiving groove disposed in the lower shell, the receiving groove being used to receive the RFID tag body;

[0007] Each outer edge of the supporting step is disposed opposite to each inner edge of the lower shell, and each outer edge is spaced from each opposite inner edge to form a receiving gap between each outer edge and each opposite inner edge.

[0008] The surface area of ​​the sealing gasket relative to the supporting step is larger than the surface area of ​​the supporting step, such that when the sealing gasket is stacked on the supporting step, each edge of the sealing gasket is directly opposite each of the receiving gaps, so that when the upper cover and the lower shell are fastened together, the edge of the sealing gasket bends toward the receiving gap.

[0009] Furthermore, the RFID tag also includes a fastening assembly, through which the upper cover and the lower shell are connected.

[0010] Furthermore, the fastening assembly includes at least one fastening member, which is disposed on one of the upper cover and the lower shell, and the other of the upper cover and the lower shell is provided with at least one groove that cooperates with the fastening member.

[0011] Furthermore, the fastening element is disposed on the upper cover, and the groove is disposed on the lower shell.

[0012] Furthermore, the fastening assembly includes a plurality of fastening members disposed on each edge of the upper cover, wherein the lower shell is provided with a plurality of grooves opposite to each of the fastening members.

[0013] Furthermore, each of the aforementioned fastening components is disposed opposite to another of the aforementioned fastening components.

[0014] Furthermore, the upper cover includes a cover body and a protrusion that bends downward along the edge of the cover body. The cover body is disposed opposite to the supporting step, and the protrusion is disposed opposite to the receiving gap.

[0015] Furthermore, the supporting step and the lower shell are integrally formed.

[0016] Furthermore, the supporting step is located in the middle of the lower shell.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In this utility model of RFID tag, the use of a sealing gasket and a supporting step allows for storage space for the RFID tag body during assembly using a receiving groove. To prevent the RFID tag body from failing due to water ingress, the sealing gasket can be stacked on the supporting step. Since the surface area of ​​the sealing gasket relative to the supporting step is larger than that of the supporting step, the edge of the sealing gasket can be located outside the edge of the supporting step and directly facing the receiving gap. Finally, the upper cover and lower shell are fastened together, allowing the edge of the sealing gasket to bend towards the receiving gap, and the middle of the sealing gasket to cover the surface of the supporting step. The sealing gasket effectively prevents water ingress into the RFID tag body. Furthermore, during installation, only the sealing gasket needs to be placed on the supporting step; no groove needs to be arranged inside the lower shell, thus solving the technical problem of inconvenient installation in the prior art.

[0024] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0025] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] Please see Figures 1 to 4 The image shows an RFID tag in one embodiment of the present invention, including an upper cover 100 and a lower shell 200 that are interlocked with each other, and also includes a sealing gasket 300 disposed in the lower shell 200 and a support step 400 having a receiving groove 410. The receiving groove 410 is used to receive the RFID tag body 500. It should be noted that the RFID tag body 500 belongs to the conventional prior art in this field, so it will not be described in detail here.

[0028] Specifically, each outer side of the supporting step 400 is arranged opposite to each inner side of the lower shell 200, and each outer side and each opposite inner side are spaced apart to form a receiving gap 600 in each outer side and each opposite inner side.

[0029] The surface area of ​​the sealing gasket 300 relative to the support step 400 is larger than that of the support step 400, such that when the sealing gasket 300 is stacked on the support step 400, each edge of the sealing gasket 300 is directly opposite each receiving gap 600, so that when the upper cover 100 and the lower shell 200 are fastened together, the edge of the sealing gasket 300 is bent toward the receiving gap 600.

[0030] In practical implementation, the receiving groove 410 provides storage space for the RFID tag body 500. To prevent the RFID tag body 500 from failing due to water ingress, in this example, a sealing gasket 300 can be stacked on top of the supporting step 400. Since the surface area of ​​the sealing gasket 300 relative to the supporting step 400 is larger than that of the supporting step 400, the edge of the sealing gasket 300 can be located outside the edge of the supporting step 400 and directly facing the receiving gap 600. Finally, the upper cover 100 and the lower shell 200 are fastened together, so that the edge of the sealing gasket 300 can be bent towards the receiving gap 600, and the middle of the sealing gasket 300 can cover the surface of the supporting step 400. The sealing gasket 300 can effectively prevent water ingress into the RFID tag body 500. During installation, the sealing gasket 300 only needs to be placed on the supporting step 400, without the need to arrange any grooves in the lower shell 200, thus solving the technical problem of inconvenient installation in the prior art.

[0031] It should be noted that the sealing gasket 300 is a flat plate structure in its initial state, and the sealing gasket 300 can be made of rubber material of existing technology, so that the sealing gasket 300 itself is flexible. Since the sealing gasket 300 is conventional existing technology, it will not be described in detail here.

[0032] In some preferred embodiments, to facilitate the fastening connection between the upper cover 100 and the lower shell 200, the RFID tag further includes a fastening component 700, through which the upper cover 100 and the lower shell 200 are connected.

[0033] Specifically, the fastening assembly 700 includes at least one fastening member 710, which is disposed on one of the upper cover 100 and the lower shell 200. The other upper cover 100 and the lower shell 200 are provided with at least one groove 720 that mates with the fastening member 710. The fastening member 710 can be a hook-shaped fastener as in the prior art. By pressing the upper cover 100, the fastening member 710 can be embedded in the groove 720 to achieve the fastening connection between the upper cover 100 and the lower shell 200.

[0034] In some other preferred embodiments, the fastening element 710 is disposed on the upper cover 100, and the groove 720 is disposed on the lower shell 200. In order to ensure the stability of the fastening connection, the fastening assembly 700 includes a plurality of fastening elements 710 disposed on each edge of the upper cover 100. The lower shell 200 is provided with a plurality of grooves 720 opposite to each fastening element 710. By utilizing the distribution of the plurality of fastening elements 710 and the plurality of grooves 720, a plurality of fastening connection fixing points are formed between the upper cover 100 and the lower shell 200. The plurality of fixing points can effectively ensure the stability of the connection between the upper cover 100 and the lower shell 200.

[0035] In addition, each fastener 710 has another fastener 710 opposite it.

[0036] Meanwhile, to facilitate bending the edge of the sealing gasket 300 toward the receiving gap 600, in this example, the upper cover 100 includes a cover body 110 and a boss portion 120 bent downward along the edge of the cover body 110. The cover body 110 is disposed opposite to the supporting step 400, and the boss portion 120 is disposed opposite to the receiving gap 600. That is, by utilizing the boss portion 120, each edge of the sealing gasket 300 can be bent toward the receiving gap 600. Furthermore, by adjusting the size of the gap in the receiving gap 600, the boss portion 120 can apply pressure to the edge of the sealing gasket 300 after extending into the receiving gap 600, causing the edge of the sealing gasket 300 to be compressed and bent, thereby ensuring waterproof performance. Similarly, downward pressure can also be applied to the middle part of the sealing gasket 300 opposite to the supporting step 400, so that the middle part of the sealing gasket 300 can be tightly fitted with the top of the supporting step 400.

[0037] In some preferred embodiments, the support step 400 and the lower shell 200 are integrally formed, and the support step 400 is located in the middle of the lower shell 200.

[0038] In summary, the RFID tag of this utility model, compared with the existing RFID tag fixing structure, has at least the following beneficial effects:

[0039] In the RFID tag of this invention, the sealing gasket 300 and the supporting step 400 provide storage space for the RFID tag body 500 during RFID tag assembly using the receiving groove 410. To prevent the RFID tag body 500 from failing due to water ingress, the sealing gasket 300 can be stacked on top of the supporting step 400. Furthermore, since the surface area of ​​the sealing gasket 300 relative to the supporting step 400 is larger than the surface area of ​​the supporting step 400, the edge of the sealing gasket 300 can be positioned within the supporting step 400. Outside the edge and facing the receiving gap 600, the upper cover 100 and the lower shell 200 are finally fastened together, so that the edge of the sealing gasket 300 can be bent toward the receiving gap 600, and the middle of the sealing gasket 300 can cover the surface of the supporting step 400. The sealing gasket 300 can effectively prevent water from entering the RFID tag body 500. In addition, during the installation process, the sealing gasket 300 only needs to be placed on the supporting step 400, without the need to arrange any grooves in the lower shell 200, thus solving the technical problem of inconvenient installation in the prior art.
