Description

Technical Field

[0001] The utility model relates to the field of communication technologies, and more specifically, to a walkie-talkie. Background Art

[0002] In various occasions that require instant communication, such as construction sites, security patrols, outdoor activities, etc. It is designed to provide a portable, durable and easy-to-operate communication tool to meet the communication needs of users in different environments. The portability of the walkie-talkie makes it an important tool for team collaboration and information transmission, while its durability ensures stable operation in harsh environments. In addition, the user interface of the walkie-talkie is usually designed to be intuitive and easy to use, so that even non-professionals can quickly get started.

[0003] For the convenience of carrying, the walkie-talkie is miniaturized. In the current technical field, in order to facilitate the startup of the miniaturized walkie-talkie, the designers place the button for starting the walkie-talkie inside one end face of the walkie-talkie housing. By pressing the end face of the walkie-talkie, local deformation is generated on the end face, and then the button is pressed to start the walkie-talkie, which also causes the end face of the walkie-talkie to adopt a soft shell material. Although this structure can expand the pressing range to facilitate the startup operation of the walkie-talkie. However, stress concentration will be generated on the end face at the button position, which is extremely likely to cause damage to the end face of the walkie-talkie. The outside of the end face of the walkie-talkie housing is also prone to wear during frequent use due to long-term pressing. Once worn, due to its non-detachable characteristic, the user cannot replace the walkie-talkie housing alone and can only choose to replace the entire walkie-talkie, resulting in a low service life of the walkie-talkie. Summary of the Invention

[0004] Aiming at the technical problem that the housing of the walkie-talkie is easily damaged due to pressing, this solution provides a walkie-talkie. In this solution, the existing technical problems can be solved by setting a pressing cover assembly.

[0005] To achieve the above object, the technical solution provided by the utility model is as follows:

[0006] A walkie-talkie, comprising

[0007] a housing assembly, the housing assembly includes a housing having an inner cavity, and a first groove is provided on an end face of the housing;

[0008] a pressing cover assembly, connected in the first groove;

[0009] a control assembly, the control assembly includes a trigger switch, the button of the trigger switch faces the pressing cover, and after the pressing cover assembly is pressed, it moves towards the inner cavity direction, contacts and activates the trigger switch.

[0010] In the walkie-talkie of the present application, the control component is used to control the startup of the walkie-talkie. When the button on the trigger switch is pressed, a call signal can be sent, and a conversation can be started after the called party responds. The trigger switch faces the gland assembly, and the gland assembly is located in the first groove provided on the end face of the housing. Since the end face area of the housing is large, the area of the gland can be set relatively large, which is convenient for pressing operations. And the gland assembly can slow down the wear at the pressing part of the housing end face and improve the service life of the walkie-talkie.

[0011] In a walkie-talkie provided by the present application, further, the gland assembly includes a first cover plate and a second cover plate detachably connected to the first cover plate. The gland assembly includes a first cover plate and a second cover plate detachably connected to the first cover plate. The first cover plate is used to connect the gland assembly to the housing, and the second cover plate is used for finger pressing. Due to the detachable connection design of the first cover plate and the second cover plate, when the first cover plate is worn, only the first cover plate needs to be replaced, and there is no need to replace the entire walkie-talkie, which saves costs and improves the service life of the walkie-talkie.

[0012] In a walkie-talkie provided by the present application, further, the outer periphery of the first cover plate is located at the bottom of the first groove and has a gap with the housing, and there is at least one bridging member connected at the gap. When the first cover plate is pressed, the bridging member can produce local deformation, so that the first cover plate can move towards the inner cavity direction. Since the first cover plate is connected to the housing in the first groove through the bridging member, the connection area between the two is small, making it easier for the bridging part to deform and bend, so that the entire first cover plate can be driven to move towards the inner cavity direction with a smaller pressing force. This avoids the inconvenience of operation caused by strong pressing and the aggravation of wear on the cover plate, and improves the service life of the cover plate. In addition, since the pressing force is reduced, the hardness of the entire first cover plate can be increased, improving its service life.

[0013] In a walkie-talkie provided by the present application, further, an annular ring is sleeved in the gap. The annular ring can fill the gap and play a certain waterproof role.

[0014] In a walkie-talkie provided by the present application, further, a pressing post extending towards the inner cavity direction is provided at the center of the first cover plate, and a threaded hole is provided on the pressing post; a threaded post is provided at the center of the second cover plate, and the threaded post is threadedly connected to the threaded hole provided at the center of the first cover plate. The bottom of the pressing post faces the trigger switch. When the second cover plate is stressed, through the threaded post provided at its center, the pressure is transmitted to the threaded post on the first cover plate. After the first cover plate is stressed, the bridging part deforms, so that the entire first cover plate moves towards the inner cavity direction, and the bottom end of the pressing post contacts the trigger switch, thereby starting the walkie-talkie. The cooperation of the pressing post and the threaded post can improve the structural strength of the gland assembly at this place and avoid the gland cracking caused by long-term use.

[0015] In a walkie-talkie provided by the present application, further, a coating or sticker with a pattern is provided on the outer end face of the second cover plate. By providing a coating or patch on the surface of the second cover plate, a user-specified pattern or photo can be formed, making the walkie-talkie more in line with customer needs and improving the overall aesthetics of the walkie-talkie.

[0016] In a walkie-talkie provided by the present application, further, a second through hole and a third through hole are provided on the outer periphery of the housing. The second through hole and the third through hole are oppositely arranged on both sides of the housing and are both communicated with the inner cavity. A "+" volume button is connected in the second through hole, and a "-" volume button is connected in the third through hole. The "+" volume button and the "-" volume button on both sides of the walkie-talkie facilitate the pressing of the volume buttons and avoid accidental pressing when on the same side.

[0017] In a walkie-talkie provided by the present application, further, a slot hole is provided on the outer periphery of the housing, and an interface for communication or charging is provided in the slot hole. The slot hole, the second through hole, and the third through hole are distributed in an isosceles triangle on the outer periphery of the housing. Being distributed in an isosceles triangle facilitates grasping and operating the walkie-talkie even when the walkie-talkie is connected to a power cord or a communication line.

[0018] In a walkie-talkie provided by the present application, further, a dust plug for opening and closing the slot hole is covered on the slot hole, and an arc-shaped groove is provided on one end side of the dust plug. By providing an arc-shaped groove on one end side of the dust plug, a fingernail can be inserted into the arc-shaped groove to remove the dust plug from the slot hole.

[0019] In a walkie-talkie provided by the present application, further, the control component includes a control panel fixed in the inner cavity. At least one antenna is vertically connected to the control panel. The antenna is built in the inner cavity, and its end faces the end face of the housing. The built-in antenna in the inner cavity is more concealed, improving the aesthetics of the walkie-talkie. In addition, the antenna is vertically fixed to the control panel, and its end faces the end face of the housing. When the housing is deformed greatly under force, it can play a certain supporting role and improve the stability of the housing.

[0020] In a walkie-talkie provided by the present application, further, a first magnetic attraction member is fixed in the end face of the housing on the side facing away from the pressing cover assembly. The first magnetic attraction member is a magnet or an iron sheet. Just fix an external magnet device, and when the walkie-talkie needs to be used, the walkie-talkie can be conveniently and quickly removed from the external magnet.

[0021] In a walkie-talkie provided by the present application, further, it includes a magnetic suction cup magnetically connected to the end face of the housing. The magnetic suction cup facilitates the carrying and taking and placing of the walkie-talkie.

[0022] In an intercom provided by the present application, further, it includes a buckle snap-fitted to the outer periphery of the intercom. The buckle can better fix the intercom, and the intercom will not fall off during strenuous exercise.

[0023] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0024] In the intercom provided by the present utility model, a control component is used to control the startup of the intercom. When the button on the trigger switch is pressed, a call signal can be sent, and a conversation can be started after the called party responds. The trigger switch faces the gland assembly, and the gland assembly is located in the first groove provided on the end face of the housing. Since the end face area of the housing is large, the gland area can be set relatively large, which is convenient for pressing operations. The gland assembly includes a first cover plate and a second cover plate detachably connected to the first cover plate. The first cover plate is used to connect the gland assembly to the housing, and the second cover plate is used for finger pressing. Due to the detachable connection design of the first cover plate and the second cover plate, when the first cover plate is worn, only the first cover plate needs to be replaced, and there is no need to replace the entire intercom, which saves costs and improves the service life of the intercom.

[0046] To further understand the content of the present utility model, the present utility model will be described in detail in combination with the drawings and embodiments. Embodiment 1

[0047] As Figure 1 shown, the present utility model provides a walkie-talkie, which includes a housing assembly 100, a gland assembly 200 and a control assembly 300. The housing assembly 100 includes a housing 120 having an inner cavity 110, and a first groove 121 is provided on the end surface of the housing 120. The gland assembly 200 is connected in the first groove 121. The control assembly 300 includes a trigger switch 310, and the button of the trigger switch 310 is facing the center of the gland. After the gland is pressed, it moves towards the inner cavity 110, contacts and activates the trigger switch 310.

[0048] In the walkie-talkie of this application, the control assembly 300 is used to control the startup of the walkie-talkie. When the button on the trigger switch 310 is pressed, a call signal can be sent, and after the called party responds, the conversation can be started. The trigger switch 310 is facing the gland assembly 200, and the gland assembly 200 is arranged in the first groove 121 provided on the end surface of the housing 120. Since the end surface area of the housing 120 is large, the gland area can be set relatively large, which is convenient for pressing operation. The gland assembly 200 includes a first cover plate 210 and a second cover plate 220 detachably connected to the first cover plate 210. The first cover plate 210 is used to connect the gland assembly 200 to the housing 120, and the second cover plate 220 is used for finger pressing. Due to the detachable connection design of the first cover plate 210 and the second cover plate 220, when the first cover plate 210 is worn, only the first cover plate 210 needs to be replaced, and there is no need to replace the entire walkie-talkie, which improves the service life of the walkie-talkie. Example 2

[0049] To facilitate the movement of the first cover plate 210 in the direction of the inner cavity 110. The outer periphery of the first cover plate 210 is connected to the bottom of the first groove 121. Specifically, a circular bottom plate 122 is provided at the bottom of the first groove 121, and the outer ring of the circular bottom plate 122 is fixedly connected to the side wall of the first groove 121. A first through hole 123 is provided at the center of the circular bottom plate 122, and the diameter of the first through hole 123 is larger than the outer diameter of the first cover plate 210. The first cover plate 210 is concentrically connected to the inner side of the first through hole 123. A gap 230 in an annular shape is formed between the inner wall of the first through hole 123 and the outer ring of the first cover plate 210. At least one bridging member 240 is arranged at the gap 230 between the inner wall of the first through hole 123 and the outer ring of the first cover plate 210.

[0050] When the first cover plate 210 is pressed, the bridging member 240 can produce local deformation, so that the first cover plate 210 can move in the direction of the inner cavity 110. Since the first cover plate 210 is connected to the housing 120 in the first groove 121 through the bridging member 240, and the connection area between the two is small, the bridging member 240 is more likely to deform and bend, so that the entire first cover plate 210 can be driven to move in the direction of the inner cavity 110 with a relatively small pressing force. The pressing difficulty and the wear speed of the cover plate are reduced, and the service life of the cover plate is improved. In addition, since the pressing force is reduced, the hardness of the entire first cover plate 210 can be increased, and its service life can be improved.

[0051] An annular ring 250 can also be sleeved in the gap 230. The annular ring 250 has a protruding portion 251, and the size and quantity of the protruding portion 251 are adapted to the gap 230 and are exactly filled into the gap 230. The annular ring 250 can fill the gap 230 and play a certain waterproof role. Example 3

[0052] To optimize the pressure transmission of the gland assembly 200. In this embodiment, a pressure column 211 extending in the direction of the inner cavity 110 is provided at the center of the first cover plate 210, and a threaded hole 212 is provided on the pressure column 211. A threaded post 221 is provided at the center of the second cover plate 220, and the threaded post 221 is threadedly connected to the threaded hole 212 provided at the center of the first cover plate 210. The bottom of the pressure column 211 faces the trigger switch 310. When the second cover plate 220 is stressed, through the threaded post 221 provided at its center, the pressure is transmitted to the threaded post 221 on the first cover plate 210. After the first cover plate 210 is stressed, deformation occurs at the bridging member 240, so that the entire first cover plate 210 moves in the direction of the inner cavity 110, and the bottom end of the pressure column 211 contacts the trigger switch 310, thereby starting the intercom. The cooperation between the pressure column 211 and the threaded post 221 can improve the structural strength of the gland assembly 200 at this place and avoid the gland cracking caused by long-term use. Example 4

[0053] To improve the aesthetics of the walkie-talkie. In this embodiment, a pattern is drawn on the second cover plate 220. Specifically, a coating 260 is provided on the surface of the second cover plate 220, and a pattern is sprayed on the coating 260 by printing technology. For example, through UV printing technology, by setting the coating 260 on the surface of the second cover plate 220, a user-specified pattern or photo can be formed, making the walkie-talkie more in line with customer needs and improving the aesthetics of the entire walkie-talkie. In addition, a pattern can also be set on the outer surface of the second cover plate 220 in the form of sticking stickers. Embodiment 5
