Description

Technical Field

[0001] The present invention relates to the technical field of communication base stations, and in particular to a mobile wireless communication device. Background Art

[0002] Mobile wireless communication devices are communication base stations that can be used in emergency situations such as field rescue. Their core working principle is mainly based on advanced radio wave transmission technology. They can efficiently receive and send radio signals through their highly sensitive antennas, thereby achieving stable communication connections with fixed base stations or other mobile devices. In the complex and changing environment of the field, this type of equipment usually uses satellite connections or temporarily built mobile base stations to ensure that rescuers can obtain reliable communication services in any geographical location, which is crucial for quickly conveying rescue instructions and coordinating the actions of all parties.

[0003] Common mobile wireless communication devices mainly include backpack communication base stations, which include a host, antenna, headset, and GPS module. The host has a communication module and battery installed inside, and the antenna is installed on the top of the host. When used in field rescue missions, the host is carried on the back of the rescuer using a backpack or strap, so as to achieve freedom of movement without affecting the rescuer's ability to maintain close contact with the command center at any time, greatly improving the efficiency and safety of the rescue operation.

[0004] As in the prior art, the patent with the authorization announcement number CN213043047U discloses an antenna and a backpack mobile device, the antenna comprising: a first antenna body, having a first top wall and a first side wall, the first top wall and the first side wall surrounding a first cavity; a second antenna body, having a second top wall and a second side wall, the second top wall and the second side wall surrounding a second cavity; wherein the first side wall and the second side wall are relatively buckled and arranged, the first cavity and the second cavity are placed between the first antenna body and the second antenna body to form an antenna cavity; the feeding point connected to the first antenna body and the second antenna body is located in the antenna cavity. The above device is formed by buckling the first antenna body and the second antenna body into a box structure, the backpack mobile device host is in the box structure, the above device saves the space occupied by the antenna, improves the portability of the backpack mobile device, and is more suitable for use in narrow environmental areas.

[0005] However, the above-mentioned mobile wireless communication device still has certain defects when in use: when conducting field rescue, if encountering terrain such as caves, the antenna in the above-mentioned mobile wireless communication device will be blocked by the top wall of the cave. At this time, it is necessary to remove the device from the backpack on the back, and then remove the antenna, and then put the device back on the back before entering the cave. However, in the rescue scenario, it takes a certain amount of time to remove the antenna, which affects the rescue efficiency. At the same time, removing the antenna in an unstable environment such as a cave may cause the communication effect of the mobile wireless communication device to be greatly reduced, resulting in the rescue personnel being unable to receive rescue information in time. The rescue personnel may face greater risks and the difficulty of rescue will also increase. Summary of the invention

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figures 1 to 13 A mobile wireless communication device comprises a device body 1 and two connectors 2 connected to the device body 1, a connecting cap 3 is threadedly connected to the outer wall of the connector 2, a fixing block 4 is connected to the top of the connecting cap 3, an antenna is connected to the surface of the fixing block 4, the antenna comprises a fixing rod 5, a connecting rod 6, a telescopic rod 7 and a communication rod 8, an installation groove 9 is opened in the fixing block 4, a motor 10 is fixedly connected in the installation groove 9, an output end of the motor 10 is connected to the bottom end of the fixing rod 5, the bottom end of the connecting rod 6 is rotatably connected to the top end of the fixing rod 5, the bottom end of the telescopic rod 7 is slidably connected to the top end of the connecting rod 6, the bottom end of the communication rod 8 is slidably connected to the top end of the telescopic rod 7, and a transmission component is connected in the connecting rod 6.

[0022] Before using the mobile wireless communication device of the present invention, the connection cap 3 is aligned with the connector 2 and then tightened, while ensuring that the rotatable direction of the fixing rod 5 is kept in the opposite position to the carrying direction of the device body 1, so that the antenna installation can be completed, and then the rescuer can carry the device body 1 to carry out rescue work; when encountering a space environment with a low top wall such as a cave, the rescuer can use the control terminal to start the motor 10, and the motor 10 will drive the fixing rod 5 to rotate in the opposite direction of the human body until the fixing rod 5 remains straight, and the antenna as a whole will change from a vertical state to a horizontal state, and the overall height of the antenna is significantly reduced, so that the rescuer can smoothly enter a low space such as a cave without disassembling the antenna, thereby greatly improving the rescue efficiency; at the same time, since the antenna is not disassembled, the communication effect of the mobile wireless communication device can be maintained, ensuring that the rescuer can receive and send rescue information in time, reducing the risks caused by poor communication, and making the rescue operation safer, faster and more effective.

[0023] As a preferred technical solution of the present invention, the transmission assembly includes a driving wheel 11, a rotating shaft 13, a driven wheel 14 and a transmission belt 15. The output end of the motor 10 is fixedly connected to the driving wheel 11. The bottom end of the fixed rod 5 is provided with a transmission groove 12 corresponding to the position of the driving wheel 11. The top of the fixed rod 5 is rotatably connected to the rotating shaft 13. The part of the rotating shaft 12 located in the transmission groove 13 is fixedly connected to the driven wheel 14. The driving wheel 11 and the driven wheel 14 are connected through the transmission belt 15. The rotating shaft 13 partially penetrates the bottom end of the connecting rod 6 and is connected to the winding assembly.

[0024] Specifically, when the fixing rod 5 is rotated to a horizontal state, the fixing rod 5 cannot rotate due to the obstruction of the device body 1. At this time, the output shaft of the motor 10 will drive the driving wheel 11 to rotate inside the fixing rod 5, and then drive the connecting rod 6 to rotate through the transmission belt 15, so that the fixing rod 5 and the connecting rod 6 are transformed into an inverted L shape, thereby avoiding the collision of the antenna with the wall caused by the twisting of the body when the rescue personnel move in narrow terrains such as caves, which not only protects the antenna from physical damage, but also ensures the freedom and safety of the rescue personnel in a small space.

[0025] As a preferred technical solution of the present invention, a telescopic groove 20 is provided in the connecting rod 6, the bottom end of the telescopic rod 7 is slidably connected to the telescopic groove 20, a telescopic spring 22 is fixedly connected between the bottom surface of the telescopic rod 7 and the bottom surface of the telescopic groove 20, a sliding groove 23 is provided in the telescopic rod 7, the bottom end of the communication rod 8 is slidably connected to the sliding groove 23, a connecting spring 24 is fixedly connected between the bottom surface of the communication rod 8 and the bottom surface of the sliding groove 23, a connecting rope 21 is fixedly connected to the bottom surface of the communication rod 8, the bottom end of the connecting rope 21 penetrates the telescopic rod 7 and the connecting rod 6, and is connected to the winding assembly.

[0026] Specifically, after the connecting rod 6 rotates to a drooping state, it will be blocked by the side wall of the device body 1. At this time, the rotating shaft 13 will rotate with the connecting rod 6, thereby driving the winding component to operate. The winding component will wind up the connecting rope 21, thereby pulling the communication rod 8, so that the communication rod 8 and the telescopic rod 7 slide into the sliding groove 23 and the telescopic groove 20 in turn, thereby reducing the length of the antenna and realizing the storage of the communication rod 8 and the telescopic rod 7, avoiding the collision of the rescue tools or legs at the waist of the rescuer when the communication rod 8 and the telescopic rod 7 are drooping, thereby ensuring the freedom of movement and safety of the rescuer in narrow spaces and low spaces, and reducing potential interference and safety hazards.

[0027] As a preferred technical solution of the present invention, the winding assembly includes a winding wheel 17, a main gear 18 and a slave gear 19. A connecting groove 16 corresponding to the position of the rotating shaft 13 is opened at the bottom end of the connecting rod 6. The winding wheel 17 is rotatably connected in the connecting groove 16. The end of the rotating shaft 13 away from the fixed rod 5 is fixedly connected to the main gear 18, and one side of the winding wheel 17 is fixedly connected to the slave gear 19. The main gear 18 is meshed with the slave gear 19, and the bottom end of the connecting rope 21 is wrapped around the outer wall of the winding wheel 17.

[0028] Specifically, when the rotating shaft 13 rotates, it will drive the main gear 18 to rotate, and then drive the slave gear 19 and the winding wheel 17 to rotate, so as to realize the winding of the connecting rope 21 and complete the storage of the communication pole 8 and the telescopic pole 7; after the rescue personnel leave the narrow space and the low space, through the control terminal, start the motor 10 to rotate in the opposite direction. At this time, the fixed pole 5 will first rotate in the opposite direction. When the fixed pole 5 rotates to a vertical state, it stops rotating, and then the connecting pole 6 rotates to a vertical state. Then the connecting pole 6 stops rotating, and then the winding wheel 17 is driven to reverse and release the connecting rope 21. At this time, under the pressure of the telescopic spring 22 and the connecting spring 24, the communication pole 8 and the telescopic pole 7 will pop out from the sliding groove 23 and the telescopic groove 20, so that the antenna is transformed into an unfolded vertical state and restored to a state that can cover a wider communication range.

[0029] It is worth noting that a baffle is fixedly connected to the fixing block 4 and the top of the fixing rod 5 on one side close to the back of the rescuer, so as to ensure that the fixing rod 5 and the connecting rod 6 will not rotate excessively and stop in time after being selected to the vertical state.

[0030] As a preferred technical solution of the present invention, a protective airbag 25 is connected to one side of the surface of the device body 1, and two fixed rope buckles 26 are fixedly connected to the bottom and the top of the side wall of the protective airbag 25. Two fixed hooks 28 are fixedly connected to the surface of the device body 1, and the two fixed hooks 28 are respectively clamped with the two fixed rope buckles 26 at the bottom of the protective airbag 25. A connecting hook 27 is fixedly connected to one side of the top of the connecting rod 6, and the connecting hook 27 is clamped with the fixed rope buckle 26 at the top of the side wall of the protective airbag 25.

[0031] Specifically, as the fixing rod 5 and the connecting rod 6 are transformed into an inverted L shape, the connecting rod 6 will pull the protective airbag 25 through the connecting hook 27 and the fixing rope buckle 26, so that the protective airbag 25 is pulled from the attached Figure 1 The state shown in the figure changes to the attached Figure 2 In the state shown in , the protective airbag 25 will cover the fixing rod 5 and the connecting rod 6, providing protection and cushioning for the fixing rod 5 and the connecting rod 6, preventing the antenna from directly colliding with the wall when the rescuer twists his body in a narrow area or near a wall, and preventing falling rocks from hitting the antenna, which can effectively prevent damage to the antenna components, extend the service life of the antenna, and ensure the stable progress of the rescue work; at the same time, when the antenna is deployed, the protective airbag 25 can also provide isolation between the antenna and the rescuer's head, avoiding direct collision between the antenna and the rescuer's head, and improving the comfort of the rescuer's neck and head.

[0032] As a preferred technical solution of the present invention, a rotation groove 29 is opened on the top of the connecting cap 3 , a rotation block 30 is rotatably connected in the rotation groove 29 , and the rotation block 30 is fixedly connected to the fixed block 4 .

[0033] Specifically, when installing the antenna, the rescue personnel first adjust the direction of the antenna to ensure that the fixing rod 5 can rotate, and then align the connecting cap 3 with the joint 2. Then, keep the fixing block 4 stationary, rotate the connecting cap 3, and tighten the connecting cap 3 and the joint 2 to achieve the installation of the antenna. This installation method can avoid the deviation of the rotation direction of the fixing rod 5 and ensure the accurate installation of the fixing rod 5 and the antenna as a whole.

[0034] As a preferred technical solution of the present invention, two symmetrically arranged positioning blocks 31 are fixedly connected to the surface of the device body 1 , and a positioning groove 32 corresponding to the position of the positioning block 31 is formed on the bottom surface of the fixing block 4 .

[0035] Specifically, the positioning block 31 and the positioning slot 32 further define the position of the antenna, ensuring the precise alignment of the antenna during installation, and also ensuring the stability of the antenna during use to prevent the fixing rod 5 from shifting.

[0036] As a preferred technical solution of the present invention, two support blocks 33 are fixedly connected to one side of the surface of the device body 1, and a support rod 34 is fixedly connected to the surface of each support block 33. The two support rods 34 are cross-arranged in an X shape and the middle parts of the two support rods 34 are fixedly connected. A shielding belt 35 is fixedly connected to the top of the two support rods 34 near the side of the protective airbag 25, and the bottom of the shielding belt 35 is connected to the bottom of the protective airbag 25.

[0037] Specifically, a V-shaped structure is formed between the shielding tape 35 and the protective airbag 25. During the use of the protective airbag 25, when it comes into contact with the wall, moss, small stones, etc. will be attached to the surface of the protective airbag 25. When the antenna is unfolded and reset, the protective airbag 25 will stand up. At this time, the moss, small stones, etc. attached thereto will slide off. Under the obstruction of the shielding tape 35, these items can be effectively prevented from entering the neck and clothes of the rescuers, and the rescuers can focus more on the rescue mission itself.

[0038] As a preferred technical solution of the present invention, a waterproof layer 36 is fixedly connected to the side of the protection airbag 25 away from the fixing rod 5 , and the bottom of the waterproof layer 36 is fixedly connected to the bottom of the shielding belt 35 .

[0039] Specifically, the waterproof layer 36 is a protective material with wear-resistant, cut-resistant, and waterproof properties, such as silicone rubber. Even if the protective airbag 25 encounters friction or cutting by sharp objects such as stones and branches, the waterproof layer 36 can provide strong protection to prevent the airbag from being worn or cut.

[0040] As a preferred technical solution of the present invention, the number of teeth and the diameter of the main gear 18 are greater than the number of teeth and the diameter of the slave gear 19 .

[0041] Specifically, the number of teeth and diameter of the main gear 18 are greater than the number of teeth and diameter of the slave gear 19 to ensure that after the main gear 18 rotates 90 degrees, the slave gear 19 can rotate more circles to reel in the connecting rope 21 and ensure the stable operation of the reel 17.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
