Technical Field

[0001] This invention relates to the field of thin film technology, specifically to a transparent antenna structure for a handheld mobile communication device. Background Technology

[0002] Police walkie-talkies, also known as police wireless walkie-talkies, are specifically designed for wireless communication between eight departments: public security, procuratorate, court, judiciary, security, customs, military, and armed police. Existing technology has developed a wireless walkie-talkie that integrates voice and data communication, offering user-friendly enhanced features. In terms of structural design and functional implementation, it provides numerous advantages, including: a large color screen, built-in dedicated antennas for BeiDou and GPS, integrated Bluetooth, intelligent audio, Chinese input method, and a large address book, making it a key business-critical device.

[0003] Walkie-talkies typically use built-in transparent film antennas for their dedicated antennas. However, the built-in installation method presents several challenges, including: 1. Since the antenna is inside the device, it often causes interference and cross-coupling between the antenna and other components; 2. Additionally, the space available for the antenna is limited, making the installation process difficult. Summary of the Invention

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 4 This invention provides a technical solution: a transparent antenna structure for a handheld mobile communication device, including a transparent antenna 3 attached to the surface of the mobile device body 1, the transparent antenna 3 facing the display screen 2 of the mobile device body 1, a set of connecting longitudinal beams 4 fitted at both ends of the transparent antenna 3, a side baffle 5 fixedly connected to the side of each set of connecting longitudinal beams 4 away from the transparent antenna 3, the side baffle 5 adhering to the side wall of the mobile device body 1, and a connecting feed pin 6 fixedly connected to the lower end of the side baffle 5, the connecting feed pin 6 having a through groove, a main contact pin 7 inserted into the groove, the main contact pin 7 fixedly inserted on the top two sides of the mobile device body 1 and connected to the circuit board, the connecting feed pin 6 being positioned on the mobile device body 1 by a fastening component, the transparent antenna 3 unfolding and closing on the mobile device body 1 with the main contact pin 7 as the rotation axis. A conductive layer is fixedly provided on the inner wall of the groove of the main contact pin 7, and a transparent conductive wire is provided on the transparent antenna 3, the transparent conductive wire passing through and connecting the longitudinal beams 4 and the side baffle 5 and connected to the conductive layer.

[0021] This invention employs an external transparent antenna, which avoids mutual interference and cross-coupling between the antenna and other internal components of the device. Furthermore, by using the connecting longitudinal beam 4, side baffle 5, adapter feed pin 6, and main contact pin 7 in conjunction, the usable space of the transparent antenna 3 is increased, making the installation process extremely smooth. On the other hand, the transparent antenna can be freely unfolded and closed, improving communication quality.

[0022] The longitudinal section of the connecting beam 4 is H-shaped. The two ends of the transparent antenna 3 are inserted into the inner groove of the connecting beam 4, and two sets of longitudinal protrusions 301 are provided at both ends of the transparent antenna 3. The connecting beam 4 is provided with contact grooves 401 to accommodate the longitudinal protrusions 301. By setting the longitudinal protrusions 301 and the contact grooves 401 in cooperation, the transparent antenna 3 and the connecting beam 4 can be quickly inserted and fixed.

[0023] The top of the mobile device body 1 is provided with four sets of auxiliary guide blocks 10, which are arranged in an alternating manner. The four sets of alternating guide blocks 10 can limit and fix the transparent antenna 3 that is flipped upward 180°, so that the unfolded transparent antenna 3 is stably connected to the circuit board inside the mobile device body 1, ensuring stable signal transmission.

[0024] The transparent antenna 3 is flipped and inserted between the four sets of auxiliary guide blocks 10, and a transverse groove 302 is provided at the end of the transparent antenna 3 near the adapter feed pin 6. Each set of guide blocks 10 has an arc-shaped protrusion 11 protruding on the side near the transparent antenna 3. The arc-shaped protrusion 11 is inserted into the transverse groove 302.

[0025] The fastening assembly includes a micro-screw 8 and a cross-head 9. One end of the micro-screw 8 is fixedly connected to the cross-head 9, and the other end of the micro-screw 8 is inserted into the main contact pin 7. The main contact pin 7 has an internal threaded groove that mates with the micro-screw 8. The cross-head 9 is made of insulating material. By using the micro-screw 8, the cross-head 9, and the main contact pin 7 together, the adapter feed pin 6 can be fixed in the adjusted position, further improving the stability of the connection between the transparent antenna 3 and the main circuit board.

[0026] In use, the present invention first unscrews the micro-screws 8 at both ends outward, then rotates the transparent antenna 3 upward by 180°, and then moves it downward and inserts it into the four sets of staggered auxiliary guide blocks 10. The transparent antenna 3 is initially fixed by the use of the arc-shaped protrusion 11 and the transverse groove 302. Then, by screwing the micro-screws 8 inward, the cross-shaped rotating head 9 is tightly attached to the outer wall of the adapter feed 6, thereby further strengthening the connection stability between the transparent antenna 3 and the circuit board inside the mobile device body 1.

[0027] When the device is not in use, the transparent antenna 3 is rotated downwards by 180° so that it fits snugly against the surface of the display screen 2. Then, the micro-screw 8 is screwed inwards again, so that the cross-shaped rotating head 9 fits tightly against the outer wall of the adapter feed pin 6, thereby fixing the adapter feed pin 6 in the adjusted position. This invention uses an external transparent antenna, which can avoid the problems of mutual interference and cross-coupling between the transparent antenna 3 and other internal components of the device; and it does not affect the normal viewing effect of the display screen 2.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
