Description
Technical Field
[0001] This invention relates to the field of communication equipment technology, and in particular to a portable tour guide for tourism. Background Technology
[0002] With the booming development of modern tourism, electronic tour guide systems have been widely used in group tours, museum tours, and various scenic spot interpretation scenarios to continuously enhance the visitor experience, becoming a key device for ensuring information transmission efficiency and service quality. Currently, most mainstream tour guide systems are based on walkie-talkie technology, adopting a "one master, multiple slaves" working mode: tour guides or interpreters broadcast audio through the master unit, while tourists receive the narration in real time through slave units; simultaneously, the system supports two-way voice communication. When group members need to communicate, they can press the PTT button to switch the device from "receive" to "transmit" mode, enabling instant communication with the tour guide or other members.
[0003] However, this traditional operating mode has significant technical bottlenecks. The core problem lies in the fact that all voice transmission operations rely on the user continuously pressing the PTT button to maintain the communication link. In actual use, tour guides' prolonged and continuous button pressing easily leads to hand fatigue, affecting the fluency of the narration and the quality of service. More seriously, if the finger accidentally releases the PTT button during the narration due to operational negligence or physical movement, communication will be immediately interrupted, resulting in intermittent or even complete loss of voice. This not only severely impacts the tourist's listening experience and disrupts the continuity of the guided tour, but may also hinder the transmission of critical information in emergencies, posing potential risks to team management, personnel scheduling, and safety. Summary of the Invention
[0004] To overcome the problems mentioned above, the present invention provides a portable tour guide for tourism.
[0005] The technical implementation of the present invention is as follows: A portable tour guide for tourism includes a housing, a main unit fixedly connected inside the housing, a communication unit provided in the main unit, a button switch fixedly connected to the housing, the button switch being used to generate a start command when the user presses it once, thereby triggering the communication unit to enter a continuous working state, two rechargeable batteries installed inside the housing, both of the rechargeable batteries being electrically connected to the main unit, and multiple cylindrical shells fixedly connected to the housing, each cylindrical shell having a trigger switch fixedly connected inside, the trigger switch being used to generate a start command when the user presses it continuously, thereby triggering the communication unit to enter a continuous working state.
[0006] Furthermore, the housing is slidably provided with a first sliding frame, and a spring is fixedly connected between the first sliding frame and the housing. The first sliding frame is slidably provided with a plurality of sliding members, the number of which is the same as the number of cylindrical shells. The sliding members are slidably connected to adjacent cylindrical shells. A sliding push rod and a sliding plate are slidably provided inside the cylindrical shell. The sliding member contacts the adjacent sliding push rod. A spring is fixedly connected between the sliding push rod and the adjacent sliding plate. A spring is fixedly connected between the sliding plate and the adjacent cylindrical shell. The sliding plate is used to press the adjacent trigger switch.
[0007] Furthermore, the spring constant between the sliding plate and the adjacent cylindrical shell is less than the spring constant between the sliding plate and the adjacent sliding push rod.
[0008] Furthermore, the cylindrical shell is fixedly connected to a fixing plate, which is slidably connected to the adjacent sliding push rod. The fixing plate has multiple first through holes and multiple second through holes. A one-way valve is installed in the first through hole. The cylindrical shell, the adjacent sliding member, the adjacent sliding push rod, and the adjacent fixing plate form a first cavity, and the cylindrical shell, the adjacent sliding push rod, and the adjacent fixing plate form a second cavity. The one-way valve in the first through hole is used for the medium in the first cavity to enter the adjacent second cavity.
[0009] Furthermore, the first cavity and the second cavity are filled with a liquid medium.
[0010] Furthermore, the flow cross-section of the first through hole is larger than that of the second through hole.
[0011] Furthermore, the first sliding frame is slidably provided with a plurality of second sliding frames, the number of which is the same as the number of the sliding members. The sliding members are provided with sliding grooves, and the second sliding frames are provided with protrusions. The protrusions of the sliding members slide within the sliding grooves of adjacent sliding members.
[0012] Furthermore, the housing is slidably provided with a sliding block, and a tension spring is fixedly connected between the sliding block and the housing. The sliding block is provided with an inclined surface, and the inclined surface of the sliding block is in contact with the first sliding frame.
[0013] Furthermore, the housing is rotatably provided with a rotating plate, which always restricts one of the batteries.
[0014] Furthermore, the housing is slidably provided with a sliding post, and a spring is fixed between the sliding post and the housing. The rotating plate is provided with two hemispherical blind holes, and the sliding post is used to insert into the corresponding hemispherical blind holes on the rotating plate.
[0015] The present invention has the following advantages: 1. This invention achieves the switching of transmission mode from "short press to start / stop, automatic maintenance" by setting a dual control mechanism of button switch and trigger switch, which effectively solves the technical problems of operation fatigue, voice interruption and poor communication reliability caused by the traditional tourist guide device relying on continuous pressing of the PTT button. 2. This invention utilizes the synergistic effect of hydraulic damping and a multi-stage elastic reset structure to control the sliding push rod to achieve delayed reset, thereby extending the signal transmission duration and realizing an intelligent response mechanism of "one press, continuous communication"; 3. This invention adopts a rotating shield structure and a dual-battery redundant power supply design, which realizes hot-swappable replacement of power modules and uninterrupted system operation, significantly improving the endurance and operational reliability of the explanation equipment.

[0018] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0019] Example 1: A portable audio guide for tourism, such as Figures 1-3 As shown, the device includes a housing 1, within which a main unit 2 is fixedly mounted. The main unit 2 is an intelligent explanation communication device that integrates PoC public network trunking intercom and full-duplex mobile calling modes, relying on a public cellular network. The main unit 2 is equipped with a communication unit 21, which consists of a microphone and speaker, used for collecting and outputting audio. A push-button switch 22 is fixedly mounted on the front side of the housing 1. The push-button switch 22 generates a start command when pressed by the user, triggering the communication unit 21 to enter continuous working state, allowing the user to explain through the device. The device continuously transmits audio information to other guide devices. Two batteries 3 are symmetrically distributed inside the housing 1. Both batteries 3 are electrically connected to the main unit 2. Four cylindrical shells 4 are fixedly attached to the left side of the housing 1. Each of the four cylindrical shells 4 has a trigger switch 5 fixedly attached inside. The trigger switch 5 is used to generate a start command when the user presses it continuously, so as to trigger the communication unit 21 to enter the continuous working state. This operation is similar to a walkie-talkie, which facilitates long-distance communication between users. At the same time, when there is no communication, the guide device maintains operation with low power consumption, effectively extending its working time.
[0020] like Figures 2-4 As shown, a first sliding frame 6 is slidably disposed on the left side of the housing 1. Three springs are fixedly connected between the first sliding frame 6 and the housing 1. Four sliding parts 7 are slidably disposed on the first sliding frame 6. The sliding parts 7 are slidably connected to the adjacent cylindrical shell 4. A sliding push rod 8 and a sliding plate 9 are slidably disposed inside the cylindrical shell 4. The sliding push rod 8 is located to the left of the sliding plate 9. The sliding parts 7 are in contact with the adjacent sliding push rod 8. A spring is fixedly connected between the sliding push rod 8 and the adjacent sliding plate 9. A spring is fixedly connected between the sliding plate 9 and the adjacent cylindrical shell 4. The elastic coefficient of the spring between the sliding plate 9 and the adjacent cylindrical shell 4 is less than the elastic coefficient of the spring between the sliding plate 9 and the adjacent sliding push rod 8. The sliding plate 9 is used to press the adjacent trigger switch 5. Four round holes are opened on the upper part of the sliding plate 9. Four round holes are opened on the right side of the cylindrical shell 4. These round holes are used for gas flow inside the cylindrical shell 4.
[0021] like Figure 4 and Figure 5As shown, a fixed plate 10 is fixedly connected inside the cylindrical shell 4. The sliding push rod 8 penetrates the adjacent fixed plate 10 and slides in a sealed manner with it. The fixed plate 10 has two first through holes 101 and two second through holes 102. A one-way valve (the one-way valve is an existing structure, which is only shown in the figure) is installed in the first through hole 101. The cylindrical shell 4, the adjacent sliding member 7, the adjacent sliding push rod 8, and the adjacent fixed plate 10 form a first cavity 103. The cylindrical shell 4, the adjacent sliding push rod 8, and the adjacent fixed plate 10 form a second cavity 104. The one-way valve in the first through hole 101 is used for the second through hole 104. The medium in the first cavity 103 enters the adjacent second cavity 104. The first cavity 103 and the second cavity 104 are filled with liquid medium. The flow cross-section of the first through hole 101 is larger than the flow cross-section of the second through hole 102. When the sliding push rod 8 moves to the left, the liquid medium in the first cavity 103 enters the second cavity 104 through the two first through holes 101 and the two second through holes 102. When the sliding push rod 8 moves to the right, the liquid medium in the second cavity 104 can only enter the first cavity 103 through the two second through holes 102, thus delaying the rightward movement of the sliding push rod 8.
[0022] like Figures 1-5 As shown, the first sliding frame 6 is slidably provided with four second sliding frames 11. The sliding member 7 is provided with a sliding groove, and the sliding groove of the sliding member 7 is inclined forward from left to right. The second sliding frame 11 is provided with a protrusion, and the protrusion of the sliding member 7 slides in the sliding groove of the adjacent sliding member 7. The housing 1 is slidably provided with a sliding block 12, and a tension spring is fixed between the sliding block 12 and the housing 1. The sliding block 12 is provided with an inclined surface, and the inclined surface of the sliding block 12 is inclined upward from left to right. The inclined surface of the sliding block 12 fits against the first sliding frame 6. The sliding block 12 is used to hinder the movement of the first sliding frame 6, provide clear feedback, and reduce misoperation.
[0023] Working principle: Before the tour, the tour guide distributes audio guides to each tourist, who wears them on their arms. The tour guide can then wear a headset connected to their own audio guide. When a narration is needed, the tour guide briefly presses button 22 on their audio guide, which enters continuous transmission mode (no need to press and hold). The tour guide's voice is captured through the headset and transmitted by the main unit 2 of the audio guide. Other tourists' audio guides (slave units) receive the signal and automatically play the tour guide's narration through their internal communication unit 21, facilitating tourists' understanding of the history of the attraction. After the narration ends, the tour guide presses button 22 again to exit transmission mode and end the tour.
[0024] If a brief message needs to be conveyed to all tourists during the tour, the tour guide presses the first sliding frame 6 once. The first sliding frame 6 compresses the spring connected to it and squeezes the inclined surface of the sliding block 12, causing the sliding block 12 to move and stretch the tension spring connected to it. At the same time, the first sliding frame 6 drives the four sliding parts 7 to move, squeezing the sliding push rod 8 to move, and causing the liquid medium in the first cavity 103 to enter the corresponding second cavity 104 through the corresponding two first through holes 101 and two second through holes 102. When the sliding push rod 8 passes through the spring connected to it, the sliding plate 9 moves, and the movement of the sliding plate 9 compresses the spring between it and the adjacent cylindrical shell 4.
[0025] After the sliding plate 9 contacts and presses the adjacent trigger switch 5, the sliding plate 9 stops moving. Then the sliding push rod 8 moves to compress the spring it is connected to. After the first sliding frame 6 stops moving, the sliding member 7 and the sliding push rod 8 stop moving at the same time. At this time, the trigger switch 5 is pressed to make the guide enter the transmission mode. In the transmission mode, the above operation is repeated to make the content conveyed by the tour guide play from the communication unit 21 of other guides, thereby completing the information transmission between the tour guide and the tourists.
[0026] When the tour guide releases the pressure on the first sliding frame 6, the first sliding frame 6 moves in the opposite direction to reset under the elastic force of the spring connected to it. Under the tension of the adjacent tension spring of the sliding block 12, the sliding block 12 moves in the opposite direction to reset. Since the elastic coefficient of the spring between the sliding plate 9 and the sliding push rod 8 is greater than that between the sliding plate 9 and the cylindrical shell 4, all the springs between the sliding plate 9 and the sliding push rod 8 first reset their deformation. At the same time, since the one-way valve in the first through hole 101 restricts the liquid medium from flowing from right to left, the liquid medium in the second cavity 104 flows only through the two adjacent second through holes 102 into the adjacent first cavity 103. Under the flow restriction effect of the second through hole 102, the sliding push rod 8 moves slowly under the elastic force of the spring connected to it. During this process, the sliding plate 9 always maintains the pressure on the adjacent trigger switch 5, keeping the guide device in the transmission mode, which facilitates the tour guide's communication for a period of time.
[0027] After the spring adjacent to the sliding push rod 8 returns to its initial length, the spring between the sliding plate 9 and the cylindrical shell 4 is reset, so that the sliding plate 9 releases the pressure on the adjacent trigger switch 5. Finally, the guide returns to its initial state. This process ensures that the guide can transmit information completely, while the communication unit 21 automatically disconnects information collection, extending the effective working time of the guide.
[0028] If a tour guide needs to communicate with one tourist individually, the tour guide presses the second sliding bracket 11 of the audio guide in the tourist's hand. The second sliding bracket 11 moves so that its upper protrusion presses against the groove of the adjacent sliding member 7, causing the sliding member 7 to press against the adjacent sliding push rod 8 to move. Then, the same transmission operation is repeated to press the designated trigger switch 5, and the tour guide can then communicate with the designated tourist individually.
[0029] Example 2: Based on Example 1, such as Figure 2 and Figure 6 As shown, a rotating plate 13 is rotatably mounted on the lower part of the housing 1. The rotating plate 13 always restricts a battery 3. A sliding column 14 is slidably mounted inside the housing 1. The sliding column 14 is provided with a hemispherical end. A spring is fixed between the sliding column 14 and the housing 1. The rotating plate 13 is provided with two hemispherical blind holes. The hemispherical end of the sliding column 14 is used to be inserted into the corresponding hemispherical blind hole on the rotating plate 13.
[0030] Specific working principle: The use of two batteries 3 significantly extends the continuous working time of the audio guide. When one of the batteries 3 reaches a low charge level, the user rotates the rotating plate 1390°. The hemispherical blind hole on the rotating plate 13 presses against the sliding column 14, causing the sliding column 14 to move and compress the spring connected to it. At this time, the rotating plate 13 releases its obstruction of the low-charge battery 3. The user can then remove the battery 3 and replace it with a new one. Afterward, the user rotates the rotating plate 1390° again. Under the elastic force of the spring connected to the sliding column 14, the sliding column 14 is reinserted into the corresponding blind hole on the rotating plate 13. This operation ensures that the audio guide is always in working condition, ensuring the timeliness of information transmission between the tour guide and the tourists.

They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
