Description

Technical Field

[0001] The present application relates to the field of radio frequency identification technology, and in particular to an RFID device. Background Art

[0002] RFID (Radio-Frequency Identification) devices use radio waves to transmit signals and collect and identify data by identifying information on tags.

[0003] RFID devices typically include a PDA (Personal Digital Assistant) and an RFID module. In the prior art, the PDA and RFID module are separate components connected via screws and other fasteners. However, this separate structure reduces the overall structural strength of the RFID device. Furthermore, because the PDA and RFID module are separate components, they require an electrical connection using a plug-in method, such as a pin connection. However, this plug-in method can lead to unstable connections, which can reduce the operational stability of the PDA and RFID module.

[0004] Therefore, how to improve the working stability and structural strength of RFID equipment is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0030] like Figure 1 and Figure 2 As shown, the present application provides an RFID device 100, which includes a housing 11, a display module 12 and an RFID module 13. Among them, the display module 12 is used for data processing and operation, and the RFID module 13 is used to scan tags and collect data. The display module 12 and the RFID module 13 are both installed in the housing 11, so that the display module 12 and the RFID module 13 can be an integrated structure, which is conducive to improving the overall structural strength of the RFID device 100. At the same time, the above-mentioned arrangement can enable the RFID module 13 to be electrically connected to the display module 12. Specifically, the RFID module 13 and the display module 12 transmit data through a wired electrical connection, so that there is no need to use a plug-in method between the RFID module 13 and the display module 12, thereby improving the stability of the signal transmission between the RFID module 13 and the display module 12, and then improving the working stability of the RFID device 100.

[0031] Specifically, the housing 11 includes a first volume 111 and a second volume 112. The display module 12 is at least partially mounted in the first volume 111, and the RFID module 13 is at least partially mounted in the second volume 112. This arrangement allows the display module 12 and the RFID module 13 to be integrated through the housing 11, eliminating the need for separate assembly of the display module 12 and the RFID module 13, thereby improving the overall structural strength of the RFID device 100. In addition, with the above arrangement, there is no need to use fasteners to assemble the display module 12 and the RFID module 13, thereby reducing the weight of the RFID device 100, making the RFID device 100 more lightweight, and thus facilitating the use of the RFID device 100 by the operator.

[0032] More specifically, the RFID module 13 and the display module 12 are directly connected via wires, eliminating the need for plug-in connections between the RFID module 13 and the display module 12. This arrangement improves the stability of signal transmission between the RFID module 13 and the display module 12, thereby improving the operating stability of the RFID device 100.

[0033] It is understood that the RFID module 13 and the display module 12 can also be connected via a flexible flat cable. Since flexible flat cables are relatively flexible and have good bending and tensile strength, the above arrangement can help improve the stability of the connection between the RFID module 13 and the display module 12, and can also allow the positions of the RFID module 13 and the display module 12 to change according to the positions of the first volume 111 and the second volume 112 within the housing 11, thereby facilitating the arrangement of the RFID module 13 and the display module 12 within the housing 11.

[0034] It should be noted that the RFID module 13 and the display module 12 can also transmit signals through other types of electrical connections, which is not limited in this application.

[0035] In this embodiment, the RFID device 100 further includes a holding mechanism 14, which is used for the operator to hold the RFID device 100. The holding mechanism 14 is located outside the housing 11 and is connected to the housing 11, thereby improving the operational convenience of the RFID device 100. Specifically, the holding mechanism 14 is also electrically connected to the display module 12. This arrangement allows the operator to control the display module 12 while holding the RFID device 100, and allows the holding mechanism 14 to control the RFID module 13 through the display module 12, thereby improving the control convenience of the RFID device 100. In some embodiments, a switch key is provided on the holding mechanism 14, and the switch key is electrically connected to the display module 12, so that the operation of the display module 12 and the RFID module 13 can be controlled by the switch key.

[0036] like Figure 2 and Figure 3 As shown, as an embodiment, the housing 11 includes an integrally formed first body 113 and a second body 114. The first body 113 includes a first volume 111, and the second body 114 includes a second volume 112. The first body 113 extends along a first preset plane 200, and the second body 114 extends along a second preset plane 300. The first preset plane 200 is not parallel to the second preset plane 300. This arrangement allows the extension plane of the second body 114 to correspond to the object to be scanned, and the extension plane of the first body 113 to be in a position convenient for the operator to observe. Thus, while the operator is using the RFID module 13 to scan an object, the operator can view the object information scanned by the RFID module 13 through the display module 12 to confirm whether the scan result is correct. This improves the operational convenience of the RFID device 100 while also enhancing viewing convenience and scanning accuracy.

[0037] More specifically, the gripping mechanism 14 is connected to the first body 113. This arrangement facilitates the connection between the gripping mechanism 14 and the display module 12 within the first volume 111, thereby simplifying the wiring between the gripping mechanism 14 and the display module 12, thereby improving the wiring compactness of the RFID device 100 and improving the structural compactness of the RFID device 100.

[0038] As an embodiment, the RFID device 100 further includes a heat dissipation mechanism 15, which is used to dissipate heat from the RFID module 13 to reduce the temperature of the RFID device 100. The heat dissipation mechanism 15 is mounted on the second body 114, and at least partially located outside the second body 114. The heat dissipation mechanism 15 also contacts the RFID module 13, thereby enabling the heat dissipation mechanism 15 to transfer heat generated by the RFID module 13 to the outside. Specifically, the heat dissipation mechanism 15 contacts the RFID module 13, allowing the heat dissipation mechanism 15 to receive heat generated by the RFID module 13. At the same time, the heat dissipation mechanism 15 is at least partially located outside the second body 114, thereby enabling the heat dissipation mechanism 15 to transfer heat generated by the RFID module 13 to the outside. This arrangement can prevent the RFID module 13 from overheating, which could cause unstable operation or even damage to the RFID module 13, thereby maintaining the RFID module 13 within a normal temperature range and improving the operational stability of the RFID module 13.

[0039] As an optional implementation, the heat dissipation mechanism 15 is made of an aluminum alloy. Specifically, aluminum alloy has a high thermal conductivity, which is conducive to improving the heat dissipation efficiency of the heat dissipation mechanism 15. In some embodiments, the heat dissipation mechanism 15 is ADC12, i.e., Aluminum-Alloy Die Castings (Aluminum Alloy Die Castings), which can be formed by recycling waste aluminum, thereby improving the heat dissipation efficiency of the heat dissipation mechanism 15 while reducing the cost of the heat dissipation mechanism 15. It should be noted that the heat dissipation mechanism 15 can also be made of other materials with heat dissipation properties, and this application is not limited thereto.

[0040] In the present application, the RFID device 100 includes a first fastener (not shown), the heat dissipation mechanism 15 and the RFID module 13 are respectively mounted on both sides of the second body 114, and the first fastener is inserted through the heat dissipation mechanism 15 and the second body 114 and fixedly connected to the RFID module 13. This arrangement allows the heat dissipation mechanism 15, the second body 114, and the RFID module 13 to be connected only by the first fastener, thereby simplifying the fixing steps of the heat dissipation mechanism 15, the second body 114, and the RFID module 13 and reducing the number of mounting points on the heat dissipation mechanism 15, the second body 114, and the RFID module 13. This simplifies the installation structure of the RFID device 100 while improving the ease of assembly and disassembly of the RFID device 100.

[0041] As an optional implementation, the heat dissipation mechanism 15 can be pre-connected to the second body 114 by bonding. This arrangement allows the heat dissipation mechanism 15 and the second body 114 to be pre-positioned, thereby reducing the difficulty of assembling the first fastener with the heat dissipation mechanism 15, the second body 114, and the RFID module 13, thereby facilitating easier assembly of the RFID device 100.

[0042] Exemplarily, the heat dissipation mechanism 15 and the second body 114 are bonded by dispensing glue, so that the heat dissipation mechanism 15 and the second body 114 are pre-connected, and then the first fastener is passed through the heat dissipation mechanism 15 and the second body 114 in sequence and connected to the RFID module 13, thereby realizing the assembly of the heat dissipation mechanism 15 and the RFID module 13 on the second body 114.

[0043] like Figure 2 and Figure 3 As shown, as one embodiment, the second body 114 defines a through-hole 1141 that communicates with the second volume 112. The heat dissipation mechanism 15 and the RFID module 13 are located on either side of the through-hole 1141. The RFID module 13 at least partially passes through the through-hole 1141 and contacts the heat dissipation mechanism 15. This arrangement allows the RFID module 13 to directly contact the heat dissipation mechanism 15, thereby improving the heat conduction efficiency between the RFID module 13 and the heat dissipation mechanism 15, and further improving the heat dissipation efficiency of the heat dissipation mechanism 15 from the RFID module 13.

[0044] It should be noted that at least a portion of the heat dissipation mechanism 15 can pass through the through hole 1141 and contact the RFID module 13. That is, at least one of the heat dissipation mechanism 15 and the RFID module 13 needs to pass through the through hole 1141 so that the heat dissipation mechanism 15 and the RFID module 13 can contact each other.

[0045] Specifically, the RFID device 100 further includes a thermal pad (not shown) located between the heat dissipation mechanism 15 and the RFID module 13. This arrangement can further improve the heat conduction efficiency between the RFID module 13 and the heat dissipation mechanism 15 through the thermal pad, thereby further improving the heat dissipation efficiency of the RFID module 13.

[0046] As one embodiment, the RFID module 13 includes a reader / writer module 131, an antenna module 132, and a module housing 133. The reader / writer module 131 is used to read and write data and is electrically connected to the display module 12, allowing data acquired by the reader / writer module 131 to be transmitted to the display module 12. The antenna module 132 is used to transmit and receive signals and is electrically connected to the reader / writer module 131, allowing signals received by the antenna module 132 to be transmitted to the reader / writer module 131. The module housing 133 is used to enclose the second volume 112 to improve the sealing of the second body 114.

[0047] Specifically, the antenna module 132 is located between the module housing 133 and the reader / writer module 131, and the reader / writer module 131 is in contact with the heat dissipation mechanism 15. Since the reader / writer module 131 is the primary heat source in the RFID module 13, the above arrangement enables the heat dissipation mechanism 15 to dissipate heat from the reader / writer module 131, thereby helping to maintain the reader / writer module 131 within a normal temperature range and, in turn, facilitating stable operation of the reader / writer module 131.

[0048] In addition, by assembling the module housing 133, the second body 114 and the heat dissipation mechanism 15, the second volume 112 can form a first basically sealed cavity, which is beneficial to improving the protection effect of the antenna module 132 and the read-write module 131 in the second volume 112, so as to prevent the antenna module 132 and the read-write module 131 from being corroded by the outside world, thereby improving the service life of the antenna module 132 and the read-write module 131. In some embodiments, the read-write module 131 is connected to the display module 12 via a flexible flat cable. In some embodiments, the read-write module 131 and the antenna module 132 are connected via a radio frequency line. That is, the present application does not limit the connection method between the read-write module 131 and the display module 12, and it is only necessary to enable data transmission between the read-write module 131 and the display module 12.

[0049] In this embodiment, the first fastener is disposed through the heat dissipation mechanism 15, the second body 114, the reader / writer module 131, and the antenna module 132, and is fixedly connected to the module housing 133. The module housing 133 is provided with a mounting post facing the antenna module 132, and the first fastener is fixedly connected to the mounting post. In some embodiments, the mounting post is a boss post, and the first fastener is a screw compatible with the boss post. The screw is disposed through the heat dissipation mechanism 15, the second body 114, the reader / writer module 131, and the antenna module 132, and is connected to the boss post, thereby achieving connection between the RFID module 13 and the second body 114 and the heat dissipation mechanism 15.

[0050] Illustratively, the heat dissipation mechanism 15 , the second body 114 , the read / write module 131 , and the antenna module 132 are all provided with fixing holes whose axes substantially coincide with each other. The first fastener is passed through the fixing holes on the above components and is threadedly connected to the mounting column.

[0051] As an optional implementation, the module housing 133 can be pre-connected to the second body 114 by bonding. This arrangement allows the module housing 133 and the second body 114 to be pre-positioned, thereby reducing the difficulty of assembling the first fastener, the module housing 133, the second body 114, and the heat dissipation mechanism 15, thereby facilitating easier assembly of the RFID module 13, the second body 114, and the heat dissipation mechanism 15.

[0052] Exemplarily, the heat dissipation mechanism 15 and the second body 114 are bonded together using glue dispenser, thereby pre-connecting the heat dissipation mechanism 15 and the second body 114. The reader / writer module 131 and the antenna module 132 are then installed in the second volume 112. The module housing 133 and the second body 114 are then bonded together using glue dispenser, thereby pre-connecting the module housing 133 and the second body 114. Finally, the first fastener is sequentially passed through the heat dissipation mechanism 15, the reader / writer module 131, and the antenna module 132 before being connected to the mounting post. These steps can reduce the difficulty of assembling the first fastener with the heat dissipation mechanism, the second body 114, and the RFID module 13, thereby improving the assembly efficiency of the RFID device 100.

[0053] It should be noted that the heat dissipation mechanism 15 and the second body 114 are bonded together by dispensing glue, which can improve the sealing between the heat dissipation mechanism 15 and the second body 114; the module shell 133 and the second body 114 are bonded together by dispensing glue, which can improve the sealing between the module shell 133 and the second body 114, thereby enabling a basically sealed cavity to be formed between the heat dissipation mechanism 15, the second body 114 and the module shell 133.

[0054] In the present application, a protrusion 1142 is formed within the second body 114, and a notch (not shown) is formed within the antenna module 132. The protrusion 1142 is at least partially located within the notch. The protrusion 1142 cooperates with the notch to restrict the position of the antenna module 132 relative to the second body 114. This arrangement prevents the antenna module 132 from shifting during use, which could lead to unstable connection with the RFID module 13, thereby improving the operational stability of the RFID module 13. Furthermore, during assembly of the RFID module 13, restricting the position of the antenna module 132 facilitates the insertion of the first fastener through the antenna module 132 for assembly, thereby improving the ease of assembly of the RFID module 13.

[0055] In one embodiment, the first predetermined plane 200 is perpendicular to the second predetermined plane 300. When viewed from a direction perpendicular to the second predetermined plane 300, the second body 114 and the gripping mechanism 14 at least partially overlap. Specifically, the RFID module 13 is mounted on the side of the second body 114 facing away from the gripping mechanism 14, and the heat dissipation mechanism 15 is mounted on the side of the second body 114 closer to the gripping mechanism 14. This arrangement facilitates the operator's ability to hold the RFID device 100 and scan codes, thereby improving the ease of use of the RFID device 100.

[0056] like Figure 4 As shown, as an embodiment, a fixing hole 1131 is provided in the first body 113, and the RFID device 100 includes a second fastener (not shown), which is passed through the fixing hole 1131 and fixedly connected to the holding mechanism 14. In some embodiments, the second fastener can be a screw. In this way, the second fastener can be set in the first body 113, thereby preventing the operator from accidentally touching the second fastener and causing the second fastener to loosen, which is beneficial to improving the connection stability between the holding mechanism 14 and the first body 113. In addition, by setting the second fastener in the first body 113, the second fastener can also be protected to prevent the second fastener from being corroded, thereby increasing the service life of the second fastener.

[0057] like Figure 2 and Figure 5As shown, as one embodiment, the display module 12 includes a display screen 121, a power module 122, a control assembly 123, an antenna assembly 124, a camera 125, and a scanning head 126. Specifically, the display screen 121 is used to display information and is used to enclose the first volume 111. This configuration allows the first volume 111 to form a substantially sealed cavity, thereby improving the protection of components installed within the first volume 111. The power module 122 is used to provide electrical energy and is at least partially mounted within the first volume 111 and is used to power the display screen 121 to enable normal operation of the display screen 121. The control assembly 123 is used to process information and is at least partially mounted within the first volume 111 and at least partially located below the display screen 121. The control assembly 123 is electrically connected to the display screen 121, the power module 122, and the RFID module 13, enabling the control assembly 123 to control the display screen 121, the power module 122, and the RFID module 13. This configuration enables the control assembly 123 to process information collected by the RFID module 13 and transmit it to the display screen 121 for display. The antenna assembly 124 is used to transmit and receive signals. The antenna assembly 124 is at least partially mounted within the first volume 111 and at least partially located below the control assembly 123. The antenna assembly 124 is electrically connected to the control assembly 123. The camera 125 is used to capture information, and the scan head 126 is used to scan information. Both the camera 125 and the scan head 126 are at least partially located within the second volume 112. Both the camera 125 and the scan head 126 are electrically connected to the control assembly 123, allowing information acquired by the camera 125 and the scan head 126 to be transmitted to the control assembly 123, thereby enabling the control assembly 123 to process the information acquired by the camera 125 and the scan head 126.

[0058] Specifically, because the first body 113 and the second body 114 are integrally formed and do not extend along the same plane, the first body 113 and the second body 114 can be considered to be formed by bending the housing 11 at the integrally formed portion of the first body 113 and the second body 114. The camera 125 and the scanning head 126 are both located at the junction of the first preset plane 200 and the second preset plane 300. That is, the camera 125 and the scanning head 126 are both located at the bend between the first body 113 and the second body 114. This arrangement allows the camera 125 and the scan head 126 to be positioned closer to components such as the display screen 121 and the control assembly 123, thereby shortening the wiring harness between the camera 125, the scan head 126, and other components, thereby reducing wiring harness costs. Furthermore, the camera 125 and the scan head 126 do not need to occupy space within the first body 113, thereby making the thickness of the first body 113 in a direction perpendicular to the first predetermined plane 200 thinner, thereby facilitating a reduction in the volume of the first body 113 and making the structure of the first body 113 more compact. Furthermore, the camera 125 and the scan head 126 can be arranged within the space within the second body 114, thereby improving the utilization rate of the space within the second body 114.

[0059] In this embodiment, a first window 1331 is provided on the module housing 133 (see Figure 3 ) and the second window 1332 (refer to Figure 3 ), the camera 125 is arranged toward the first window 1331, and the scanning head 126 is arranged toward the second window 1332. This arrangement allows the camera 125 to obtain external information through the first window 1331, and the scanning head 126 to obtain external information through the second window 1332, thereby facilitating shooting by the camera 125 and scanning by the scanning head 126.

[0060] As an optional implementation, the control assembly 123 includes a main control board 1231 and a sub-control board 1232, with the sub-control board 1232 being electrically connected to the main control board 1231. A first mounting space 1233 is formed between the main control board 1231 and the sub-control board 1232, and the power module 122 is at least partially located within the first mounting space 1233. This arrangement provides a mounting location for the power module 122, eliminating the need for the power module 122 to be installed below or below the control assembly 123. This helps reduce the layout space of the display module 12, thereby reducing the size of the RFID device 100, improving the portability and compactness of the RFID device 100.

[0061] Specifically, the antenna assembly 124 includes a main antenna mechanism 1241 and a sub-antenna mechanism 1242, which are electrically connected to the uniform control assembly 123. The main antenna mechanism 1241 is located below the sub-control board 1232, while the sub-antenna mechanism 1242 is located below the main control board 1231. A second mounting space 1243, which communicates with the first mounting space 1233, is formed between the main antenna mechanism 1241 and the sub-antenna mechanism 1242. The power module 122 is also at least partially located within the second mounting space 1243. This arrangement allows the second mounting space 1243 to cooperate with the first mounting space 1233 to provide mounting space for the power module 122, eliminating the need for the power module 122 to be installed above or below the antenna assembly 124. This further reduces the layout space required for the display module 12 and the size of the RFID device 100, further enhancing the portability and compactness of the RFID device 100.

[0062] As an optional implementation, the control assembly 123 also includes a power board 1234, which is located below the secondary antenna mechanism 1242. This configuration allows the installation of a control processor on the power board 1234, thereby avoiding the added complexity of manufacturing the main control board 1231 and the secondary control board 1232 by adding too many control processors. This, in turn, helps simplify the structures of the main control board 1231 and the secondary control board 1232. Furthermore, the power board 1234 can increase the control functionality of the control assembly 123, thereby enhancing the functional diversity of the display module 12.
