Description

Technical Field

[0001] The invention relates to the technical field of intercoms, and in particular to a high-strength anti-fall intercom. Background Art

[0002] As a communication device widely used in military, construction, security, emergency rescue, mining and other fields, walkie-talkies have been continuously expanded in performance and application scenarios with the development of technology in recent years. In some high-intensity and high-risk working environments, the drop resistance and durability of traditional walkie-talkies are gradually unable to meet the needs, so the drop resistance of walkie-talkies has become one of the key directions for technical improvement.

[0003] In the prior art, many walkie-talkies have been improved in design to improve their ability to resist falling. For example, some walkie-talkies use materials such as reinforced plastics, rubber wrapping, and metal alloy shells, and enhance their impact resistance through internal buffering design. Although many walkie-talkies in the prior art have been improved in anti-fall design, especially in the material and structure of the body shell, there are still certain deficiencies in the protection and anti-fall ability of the antenna part. As an important component of the walkie-talkie, the antenna directly affects the communication performance and signal reception quality of the device.

[0004] The existing anti-fall walkie-talkies also face the problem of conflict with the anti-fall design when designing antennas. To ensure good signal transmission, the antenna usually needs to have a certain length, and this design often faces structural challenges in anti-fall walkie-talkies. The antenna is easily damaged when it falls or encounters external impact, thus affecting the reliability of the walkie-talkie. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a high-strength anti-fall intercom, aiming to alleviate the above-mentioned problems at least to a certain extent.

[0014] a locking component provided between the connecting component and the antenna part, used to lock the position of the antenna part when the antenna part moves up to a preset position after the rotating shaft is connected to the connecting shaft through the connecting component;

[0015] The unlocking component arranged between the antenna connecting part and the locking component is used for rotating the connecting shaft to move the antenna connecting seat downward when the front end of the antenna part is hit.

[0026] By setting a connecting component, when the intercom is in use, the antenna part is plugged into the antenna connection seat to achieve signal transmission and reception. In the initial state, the antenna part and the antenna connection shaft are stored in the storage cavity. When the intercom is in use, the connecting component can be used to connect the rotating shaft and the connecting shaft, and the rotating shaft can be rotated. The rotating shaft rotates the connecting shaft through the connecting component, and the position of the antenna connection seat can be moved upward by the moving component. The upward movement of the antenna connection seat can allow the antenna part to move out of the storage cavity to better receive and transmit signals. When the antenna connection seat and the antenna part move upward to the preset position, the locking component can lock the position of the antenna part and position the antenna part. The one-way rotating part set between the rotating shaft and the storage cavity ensures that the antenna will not be reset and rotated due to external force or unnecessary operation, causing the antenna part to be accidentally stored when the intercom is in normal use. If the intercom is accidentally dropped, the antenna part is hit by external force, and the unlocking part between the connecting part and the locking part is automatically triggered. By resetting the rotating connecting shaft, the unlocking mechanism causes the antenna connection seat to move down, thereby retracting the antenna part into the storage cavity to prevent the antenna from being damaged by external impact. Through this design, the antenna part can be easily extended when in use and ensure stable signal transmission, and can be automatically retracted when impacted. The present application can not only conveniently extend the antenna part when the intercom is used to ensure stable signal transmission, but also automatically retract when facing a fall or external force impact to avoid antenna damage, thereby improving the anti-fall ability and durability of the intercom. This retractable and self-protection design allows the antenna to improve the functionality of the intercom while taking into account the safety and long-term reliability of the equipment. Compared with the traditional antenna design, this design effectively solves the problem of the antenna being easily damaged, especially in a high-intensity use environment, ensuring that the intercom can still maintain good working performance in daily use, extreme falls, etc. This not only improves the anti-fall ability of the intercom, but also enhances the user experience.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] refer to Figure 1-Figure 10 , a high-strength anti-fall walkie-talkie, comprising:

[0046] Intercom 100;

[0047] A storage chamber 101 provided on the intercom 100;

[0048] An antenna part 102 is arranged on the storage cavity 101. An antenna connection seat 103 is arranged in the storage cavity 101. The antenna part 102 is plugged into the antenna connection seat 103.

[0049] A rotating shaft 104 is disposed on the receiving chamber 101, a connecting shaft 105 is disposed at the bottom of the rotating shaft 104, and a one-way rotating portion 106 is disposed between the rotating shaft 104 and the receiving chamber 101;

[0050] A connecting member disposed between the rotating shaft 104 and the connecting shaft 105, used to connect the rotating shaft 104 and the connecting shaft 105, so that the connecting shaft 105 rotates when the rotating shaft 104 rotates;

[0051] A moving component disposed between the rotating shaft 104 and the antenna connecting seat 103, used to move the antenna connecting seat 103 up and down when the connecting shaft 105 rotates;

[0052] A locking component provided between the connecting component and the antenna portion 102, used to lock the position of the antenna portion 102 when the antenna portion 102 moves up to a preset position after the rotating shaft 104 is connected to the connecting shaft 105 through the connecting component;

[0053] The unlocking component is disposed between the antenna connecting portion and the locking component, and is used to rotate the connecting shaft 105 to allow the antenna connecting seat 103 to move downward when the front end of the antenna portion 102 is hit;

[0054] By providing the connection component, when the intercom 100 is used, the antenna part 102 is plugged into the antenna connection socket 103 to achieve signal transmission and reception. In the initial state, the antenna part 102 and the antenna connecting shaft 105 are stored in the storage cavity 101. When the walkie-talkie 100 is in use, the connecting component can be used to connect the rotating shaft 104 and the connecting shaft 105, and the rotating shaft 104 can be rotated. The rotating shaft 104 rotates the connecting shaft 105 through the connecting component, and the moving component can be used to move the position of the antenna connecting seat 103 upward. The upward movement of the antenna connecting seat 103 can allow the antenna part 102 to move out of the storage cavity 101 to better receive and transmit signals. When the antenna connecting seat 103 and the antenna part 102 move upward to a preset position, the provided locking component can lock the position of the antenna part 102 to position the antenna part 102, and the one-way rotating part 106 provided between the rotating shaft 104 and the storage cavity 101 ensures that the antenna will not be reset and rotated due to external force or unnecessary operation, causing the antenna part 102 to be accidentally stored when the walkie-talkie 100 is in normal use. If the intercom 100 is accidentally dropped, the antenna part 102 is hit by an external force, and the unlocking part between the connecting part and the locking part is automatically triggered. By resetting the rotating connecting shaft 105, the unlocking mechanism causes the antenna connection seat 103 to move downward, thereby retracting the antenna part 102 into the storage cavity 101 to prevent the antenna from being damaged by external impact. Through this design, the antenna part 102 can be conveniently extended when in use and ensure stable signal transmission, and can be automatically retracted when impacted. The present application can not only conveniently extend the antenna part 102 when the intercom 100 is used to ensure stable signal transmission, but also automatically retract when facing a fall or external force impact, avoiding antenna damage, and improving the anti-fall ability and durability of the intercom 100. This retractable and self-protection design allows the antenna to improve the functionality of the intercom 100 while taking into account the safety and long-term reliability of the device. Compared with the traditional antenna design, this design effectively solves the problem of the antenna being easily damaged, especially in a high-intensity use environment, ensuring that the intercom 100 can still maintain good working performance in daily use, extreme falls, etc. This not only improves the drop resistance of the intercom 100, but also enhances the user experience.

[0055] As a further solution of the present invention, the connecting component includes a sliding shaft 200 slidably connected to the rotating shaft 104, the bottom of the sliding shaft 200 extends to the bottom of the rotating shaft 104 and is connected to a limiting disk 201, the limiting disk 201 is slidably connected to the top of the connecting shaft 105, and the bottom of the rotating shaft 104 is connected to a limiting sleeve 202 adapted to the limiting disk 201;

[0056] By setting the sliding shaft 200, when in use, the position of the sliding shaft 200 can be lifted upward, so that the limiting plate 201 can be moved upward through the sliding shaft 200 to engage with the limiting sleeve 202. When the rotating shaft 104 is subsequently rotated, the connecting shaft 105 can be limited by the limiting sleeve 202 and the limiting plate 201, thereby achieving the purpose of connecting the rotating shaft 104 with the connecting shaft 105.

[0057] As a further solution of the present invention, the moving component includes a moving frame 300 slidably connected to the storage chamber 101, the moving frame 300 is connected to the antenna connection seat 103, a lead screw 301 is rotatably connected to the storage chamber 101, and the moving frame 300 is threadedly connected to the lead screw 301;

[0058] By providing the lead screw 301, when the lead screw 301 rotates, the moving frame 300 cooperates with the lead screw 301 through a threaded connection, driving the antenna connection seat 103 to move up and down along the track of the storage chamber 101. Since the rotational movement of the lead screw 301 is a precise linear drive, this design ensures that the antenna connection seat 103 can move up and down in a stable and controllable manner, so that the antenna part 102 can be smoothly extended or retracted from the storage chamber 101.

[0059] As a further solution of the present invention, the moving component further includes a traction rope a302 wound on the connecting shaft 105, one end of the traction rope a302 is wound on the lead screw 301, and a spring a303 is provided between the lead screw 301 and the storage chamber 101;

[0060] By providing the traction rope a302, when the user rotates the rotating shaft 104, the connection shaft 105 can be rotated through the limit plate 201 and the limit sleeve 202, and the rotation of the connecting shaft 105 can reel in the traction rope to rotate the lead screw 301, thereby achieving the purpose of rotating the lead screw 301 to move the antenna connection seat 103. In addition, the provided spring a303 can generate potential energy by twisting when the lead screw 301 rotates, and after the rotating shaft 104 and the connecting shaft 105 are connected by the connecting component, the one-way rotating part 106 will limit the connecting shaft 105 while limiting the rotating shaft 104, thereby limiting the reverse rotation of the lead screw 301. When the antenna part 102 is subsequently stored, it is only necessary to allow the connecting component to release the connection between the rotating shaft 104 and the connecting shaft 105, and the spring a303 will instantly release the potential energy, so that the antenna part 102 can be stored.

[0061] As a further solution of the present invention, the antenna part 102 includes a rubber rod 400, on which a radiation element 401 is provided, which is clamped with the antenna connection seat 103 and is used for radiating and receiving signals;

[0062] By providing the rubber rod 400 and the radiation element 401, the antenna unit 102 can enhance the drop resistance and durability while ensuring the signal transmission effect. The rubber rod 400 has a certain flexibility and elasticity, which can effectively absorb external impact force and reduce the damage to the antenna unit 102 when it falls or collides. Since the rubber material has a strong fracture resistance, the antenna unit 102 is not easy to break when facing a severe impact, thereby improving the drop resistance of the walkie-talkie 100.

[0063] As a further solution of the present invention, the locking component includes a connecting groove 402 opened on one side of the rubber soft rod 400, a positioning clip 403 is slidably connected to the bottom of the connecting groove 402, a spring b404 is connected between the positioning clip 403 and the connecting groove 402, a limiting clip rod 405 slidably connected to the storage cavity 101 is rotatably connected to the limiting plate 201, and the positioning clip strip 403 is clamped with the limiting clip rod 405;

[0064] By setting the spring b404, the spring b404 can limit the position of the positioning card strip 403. When the antenna part 102 moves upward to the preset position, the positioning card strip 403 can be engaged with the limiting card rod 405, which can limit the position of the limiting card disc so that it will not move downward and disengage from the limiting sleeve 202 during normal operation, thereby achieving the purpose of limiting the antenna part 102. This design enables the antenna part 102 to automatically position and remain stable during the lifting process through the cooperation of the spring b404 and the clamping mechanism. Once the antenna part 102 moves to the preset position, the pressure generated by the spring b404 will help the positioning card strip 403 to be firmly engaged with the limiting card rod 405, thereby preventing the antenna part 102 from being loosened or shifted unnecessarily during use. In this way, the antenna part 102 can work stably under normal working conditions, avoiding signal loss or equipment failure caused by antenna instability.

[0065] As a further solution of the present invention, the unlocking component includes a collision plate 500 arranged on the top of the rubber soft rod 400, the bottom of the collision plate 500 is connected to a connecting ball 501 sleeved with the rubber soft rod 400, a plurality of springs c502 are connected between the collision plate 500 and the rubber soft rod 400, the bottom of the connecting ball 501 is connected to a traction rope b503, one end of the traction rope b503 passes through the rubber soft rod 400 and is connected to the positioning card strip 403;

[0066] By setting the unlocking mechanism of the collision piece 500, the connecting ball 501 and the traction rope b503, the antenna part 102 can automatically trigger the storage mechanism when it encounters an external force impact or falls, ensuring that the antenna part 102 can be safely recovered. When the intercom 100 accidentally falls and causes the antenna part 102 to touch the ground, the collision piece 500 will be impacted by the external force and deflected, causing the connecting ball 501 to rotate and produce a certain amount of displacement. At this time, the displacement is transmitted through the traction rope b503, and the traction rope b503 will pull the positioning card strip 403, and use the instantaneous force to cause the positioning card strip 403 to disengage from the limit card rod 405. Once the positioning card strip 403 is disengaged from the limit card rod 405, the limit card rod 405 can move downward and allow the limit plate 201 to disengage from the limit sleeve 202. This disengagement action can immediately release the antenna part 102 from the fixed position, and the antenna connection seat 103 will automatically move downward under the action of the spring a303, thereby retracting the antenna part 102 into the storage cavity 101. The setting of this unlocking mechanism greatly improves the drop resistance and self-protection ability of the antenna part 102, and effectively prevents the antenna from being damaged due to external impact.

[0067] As a further solution of the present invention, the one-way rotating portion 106 includes a ratchet mechanism 107 disposed between the rotating shaft 104 and the receiving chamber 101;

[0068] By providing the ratchet mechanism 107 , the lifting process of the antenna portion 102 can be effectively unidirectionally controlled, thereby preventing the antenna from being accidentally stored or misplaced due to unnecessary operations or external forces during use.

[0069] As a further solution of the present invention, a connecting tube 600 is provided in the storage cavity 101, a pendant 601 is provided in the connecting tube 600, a traction rope c602 is connected to the top of the pendant 601, and one end of the traction rope c602 is connected to the limit clamp rod 405;

[0070] By setting the pendant 601, the pendant 601 in the connecting tube 600 is connected to the traction rope c602. Under the action of external vibration or impact, the pendant 601 will produce a certain displacement, thereby pulling the traction rope c602. The other end of the traction rope c602 is connected to the limit clamp rod 405, and the displacement of the pendant 601 is transmitted to the limit clamp rod 405 through the traction rope c602. The limit clamp rod 405 can overcome the force of the spring b404 and move downward, so that the limit clamp disc is separated from the limit sleeve 202, and the vibration-triggered storage function of the antenna part 102 can be realized.

[0071] As a further solution of the present invention, the connecting tube 600 is a copper tube and the pendant 601 is a magnet;

[0072] By providing the copper tube and the magnet design, the damping of the movement of the pendant 601 can be effectively increased to ensure that the antenna unit 102 will not be accidentally retracted due to slight vibration or external force during normal use of the intercom 100. This design helps to avoid unnecessary malfunctions, thereby improving the stability of the device.

[0073] 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.
