Description

Technical Field

[0001] This application relates to the field of communication intercom technology, and in particular to a locking module and a communication device having a locking module. Background Technology

[0002] Walkie-talkies are terminal devices for trunked radio communication. In daily use, the walkie-talkie body is designed to be securely held on a fixed base and easily removed from it. In existing technology, the inner wall of the fixed base is provided with a resiliently extendable latch, which uses the pressure of the latch acting on the outer surface of the walkie-talkie body to restrict the walkie-talkie body to the fixed base.

[0003] Taking a walkie-talkie placed flat on a table as an example, since the force of the latch is roughly parallel to the walkie-talkie body, when placing the walkie-talkie, the user needs to tilt it at a certain angle relative to the horizontal plane. Correspondingly, the user needs to apply a certain force to the walkie-talkie body along the direction of the tilt to make the walkie-talkie body push the latch back horizontally. The operation is the same when picking it up, but the direction of the force is reversed. This does not conform to the user's operating habits and causes inconvenience. Summary of the Invention

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

The terms "first" and "second" are used only for the purpose of description and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality" means two or more, unless otherwise explicitly specified.

[0048] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0049] Please see Figure 1 , Figure 3 and Figure 4 As shown in the figure, this application embodiment provides a communication device 200, which includes a communication body 8, a base 9, and at least one locking module 100. A portion of the locking module 100 is disposed on the base 9, and another portion is disposed on the communication body 8. The locking module 100 is used to detachably mount the communication body 8 onto the base 9. The base 9 is used for fixed installation in a working position, such as a wall or a workbench surface.

[0050] Please refer to the following for details. Figure 4 , Figure 5 and Figure 6 As shown, the locking module 100 includes a support member 3, multiple limiting members 4, a locking part 2, and a reset member 5. Specifically, the support member 3 is used to fix it on the base 9, and each limiting member 4 includes an interconnected shaft part 41 and a rotating arm 42, as shown in the reference. Figure 7 and Figure 8 As shown, each shaft 41 is rotatably mounted on the support member 3 about its own central axis (defined as its own first axis X); the locking part 2 is fixedly connected to the housing 82 of the communication body 8; the reset member 5 is provided on the support member 3 and is used to provide a restoring force to the rotating arm 42 that rotates toward the locking part 2; the locking part 2 together with the entire communication body 8 can move along the second axis Y, and each first axis X is perpendicular to the second axis Y.

[0051] Among them, such as Figure 6 , Figure 7 and Figure 8 As shown, the end of the rotating arm 42 opposite to the shaft portion 41 is provided with a hook portion 421, the hook portion 421 having a first guide surface 4211 and a second guide surface 4212, as... Figure 9 and Figure 10 As shown, the first guide surface 4211 and the second guide surface 4212 gradually expand outward from each other in the direction away from the locking part 2, and the first guide surface 4211 is located on the side of the hook part 421 facing the shaft part 41, and the second guide surface 4212 is located on the side of the hook part 421 away from the shaft part 41; the locking part 2 is provided with a third guide surface 23 and a fourth guide surface 24, the third guide surface 23 is located on the side of the locking part 2 facing the shaft part 41, and the fourth guide surface 24 is located on the side of the locking part 2 away from the shaft part 41, and the third guide surface 23 and the fourth guide surface 24 gradually contract inward from each other in the direction towards the hook part 421; the second guide surface 4212 is used for sliding engagement with the third guide surface 23, and the first guide surface 4211 is used for sliding engagement with the fourth guide surface 24. That is, the first guide surface 4211 and the second guide surface 4212 both have a certain angle relative to the first axis X and the second axis Y, thus presenting a relative outward expansion, while the third guide surface 23 and the fourth guide surface 24 both have a certain angle relative to the first axis X and the second axis Y, thus presenting a relative inward contraction.

[0052] When it is necessary to lock the latch 2 onto the rotating arm 42, the user holds the latch 2 and moves the latch 2 along the second axis Y toward the base 9. Figure 9 and Figure 10 (The solid arrow in the image indicates the direction of movement). Please refer to [link / reference]. Figure 9 and Figure 10As shown, the third guide surface 23 of the locking part 2 slides relative to the second guide surface 4212 of the hook part 421. During the sliding process, the locking part 2 gradually moves closer to the shaft part 41 along the second axis Y, and pushes the hook part 421 to rotate away from the locking part 2. Figure 9 and Figure 10 (The solid arrow in the arc indicates the direction of rotation). During this process, energy is stored in the reset member 5. When the locking part 2 continues to move along the second axis Y and passes the second guide surface 4212, the reset force provided by the reset member 5 to the rotating arm 42 causes the rotating arm 42 to automatically rotate toward the locking part 2, so that the fourth guide surface 24 abuts against the first guide surface 4211. Please refer to [reference needed]. Figure 6 and Figure 10 As shown, at this time, the locking part 2 is restricted by the hook part 421 to the side facing the shaft part 41, and the locking part 2 cannot disengage from the hook part 421 on the square of the second axis Y. In this way, the locking part 2 is locked onto the rotating arm 42.

[0053] Conversely, when it is necessary to detach the locking part 2 from the rotating arm 42, the user holds the locking part 2 and moves it away from the base 9 along the second axis Y. The fourth guide surface 24 of the locking part 2 slides relative to the first guide surface 4211 of the hook part 421. During the sliding process, the locking part 2 gradually moves away from the shaft part 41 and pushes the hook part 421 to rotate away from the locking part 2. During this process, as the rotating arm 42 rotates away from the locking part 2, energy is stored in the reset member 5. When the locking part 2 continues to move along the second axis Y and passes the first guide surface 4211, the reset force provided by the reset member 5 to the rotating arm 42 causes the rotating arm 42 to automatically rotate towards the locking part 2 and return to its initial position. In this way, the locking part 2 is detached from and unlocked from the rotating arm 42.

[0054] During the above locking and unlocking process, the force applied by the user to the latch 2 is approximately along the second axis Y, that is, approximately from the communication body 8 to the base 9 and the support 3.

[0055] The communication device 200 and its locking module 100 provided in this application embodiment, through the cooperation of the third guide surface 23 and the fourth guide surface 24 of the locking part 2, and the first guide surface 4211 and the second guide surface 4212 of the hook part 421, enable the locking part 2 to be installed and disassembled in a direction perpendicular or substantially perpendicular to the support member 3. When the user uses the locking module 100 and the communication body 8, the force applied to the communication body 8 is perpendicular or substantially perpendicular to the base 9, which conforms to the user's operating habits and force application habits, resulting in a good user experience. Furthermore, compared with the prior art solution where the buckle abuts against the side of the intercom body, the hook part 421 restricts the locking part 2 in the picking and placing direction of the communication body 8, making the installation of the communication body 8 more stable. Even if the side, bottom, or top surface of the communication device 200 is subjected to impact force, the locking part 2 is not easy to detach from the hook part 421.

[0056] The support member 3 is fixedly connected to the base 9. This includes, in some embodiments, the support member 3 being integrally formed with the base 9, or separately formed and connected to the base 9, or the support member 3 being a part of the base 9. Specifically, as follows... Figure 3 , Figure 4 , Figure 5 As shown, the part of the base 9 corresponding to the locking part 2 can serve as a support member 3.

[0057] Similarly, the locking part 2 is fixedly connected to the communication body 8. This includes the locking part 2 being integrally formed with the housing 82 of the communication body 8, or being separately formed and connected together, or the locking part 2 being part of the housing 82. For details, please refer to the relevant documentation. Figure 2 , Figure 3 and Figure 6 As shown in the embodiment of this application, the latching part 2 is fixed to the housing 82 of the communication body 8 by a first fastener (not shown). For example, the latching part 2 is detachably connected to the housing 82 of the communication body 8 by bolts or the like, or the latching part 2 is non-detachably installed on the housing 82 of the communication body 8 by welding or the like.

[0058] In each locking module 100, there are multiple limiting members 4, and the multiple limiting members 4 can be distributed at intervals in a plane perpendicular to the second axis Y to restrict multiple positions of the locking part 2 and ensure that multiple areas on the locking part 2 are locked; further optionally, multiple rotating arms 42 are evenly distributed in a ring in a plane perpendicular to the second axis Y.

[0059] like Figure 4 , Figure 5 and Figure 6 As shown in this embodiment, there are two rotating arms 42. In other alternative embodiments, the number of rotating arms 42 may be three, four, or more, depending on the specific needs.

[0060] It is understandable that each limiting member 4 has its own first axis X, rather than all limiting members 4 rotating around the same axis. Optionally, each first axis X is located in the same plane. In this case, the rotation stroke, angle, etc. of each rotating arm 42 can be kept completely consistent at any time, and the limiting effect on different positions of the locking part 2 is the same, which helps to ensure the installation stability of the locking part 2 and the communication body 8 on the base 9.

[0061] like Figure 6 , Figure 9 and Figure 10 As shown, if there are two limiting members 4, the two first axes X are parallel to each other. When there are three limiting members 4, the three first axes X can be arranged at a 120° angle to each other.

[0062] Multiple limiting members 4 respectively cooperate with a portion of the locking part 2. The locking part 2 can be located between the multiple limiting members 4. Correspondingly, hooks 421 are provided on the adjacent sides of the rotating arm 42; please refer to [reference needed]. Figure 6 , Figure 9 and Figure 10 As shown.

[0063] Alternatively, please see Figure 11 As shown, the locking part 2 is arranged around multiple limiting members 4, and the hook part 421 is arranged on the opposite side of the rotating arm 42.

[0064] This application embodiment is mainly described using the example of the locking part 2 being located between multiple limiting members 4. The second axis Y can be configured to pass through the locking part 2, and the multiple limiting members 4 are evenly distributed around the second axis Y.

[0065] The shaft portion 41 in the limiting member 4 is used to form a rotational fit with the bearing member 3; therefore, the form of the shaft portion 41 is not limited. Please refer to [reference needed]. Figure 6 , Figure 7 and Figure 8 As shown, the shaft portion 41 may include a protruding cam 411 protruding relative to the rotating arm 42 along the first axis X, the cam 411 being used to mate with a shaft hole on the support member 3. Conversely, the shaft portion 41 may also be a shaft hole recessed relative to the rotating arm 42 along the first axis X, the shaft hole being used to mate with a cam structure on the support member 3.

[0066] like Figure 4 and Figure 5As shown, the periphery of the locking part 2 is at least partially rounded. Correspondingly, in the direction surrounding the second axis Y, both the third guide surface 23 and the fourth guide surface 24 are at least partially curved surfaces. Specifically, in the direction surrounding the second axis Y, both the third guide surface 23 and the fourth guide surface 24 are arc surfaces, or even circles. That is to say, the intersection line obtained by cutting the third guide surface 23 and the fourth guide surface 24 with a plane perpendicular to the second axis Y is a circle or an arc. In a specific embodiment, as... Figure 6 As shown, the intersection line obtained by cutting the third guide surface 23 and the fourth guide surface 24 with a plane perpendicular to the second axis Y is a circle.

[0067] Accordingly, such as Figure 8 As shown, both the first guide surface 4211 and the second guide surface 4212 are curved surfaces in the direction surrounding the second axis Y. Optionally, both the first guide surface 4211 and the second guide surface 4212 are circular arc surfaces in the direction surrounding the second axis Y. That is to say, the intersection line obtained by cutting the first guide surface 4211 and the second guide surface 4212 with a plane perpendicular to the second axis Y is a circular arc.

[0068] In other alternative embodiments, the locking portion 2 may be polygonal, for example, quadrilateral or even square, along the direction of the second axis Y. Correspondingly, the hook portion 421 may be formed corresponding to the edge of the locking portion 2. No particular limitation is made here.

[0069] In one embodiment, in the direction along the second axis Y, the third guide surface 23 and the fourth guide surface 24 are both convex or flat surfaces, and the first guide surface 4211 and the second guide surface 4212 are both flat or convex surfaces. Figure 5 As shown in the cross-sectional view, or in other words, when the locking part 2 and the hook part 421 are cut with a plane passing through the second axis Y, the resulting intersection lines are all straight lines or convex lines. The purpose of this arrangement is to facilitate the processing and manufacturing of the locking part 2 and the limiting member 4.

[0070] In one embodiment, please refer to Figure 6 , Figure 8 and Figure 10As shown, in the direction along the second axis Y, one of the fourth guide surface 24 and the first guide surface 4211 is a convex arc surface, and the other is a plane. That is, when the plane passing through the second axis Y cuts the fourth guide surface 24 of the latch part 2 and the first guide surface 4211 of the hook part 421, one of the two intersecting lines is a convex arc line, and the other is a straight line. The purpose of this arrangement is that, during the movement of the latch part 2 along the second axis Y, the first guide surface 4211 and the fourth guide surface 24 are in point contact (in line contact in the direction surrounding the second axis Y), which helps to reduce the friction between the first guide surface 4211 and the fourth guide surface 24, making it easier for the user to operate and lock the latch part 2.

[0071] In one embodiment, please refer to Figure 6 , Figure 8 and Figure 10 As shown, in the direction along the second axis Y, one of the second guide surface 4212 and the third guide surface 23 is a convex arc surface, and the other is a plane. That is, when the plane passing through the second axis Y cuts the third guide surface 23 of the latching part 2 and the second guide surface 4212 of the hook part 421, one of the two intersecting lines is a convex arc line, and the other is a straight line. The purpose of this arrangement is that, during the movement of the latching part 2 along the second axis Y, the second guide surface 4212 and the third guide surface 23 are in point contact (in line contact in the direction surrounding the second axis Y), which also helps to reduce the friction between the second guide surface 4212 and the third guide surface 23, making it easier for the user to disassemble the latching part 2.

[0072] In one specific embodiment of this application, please refer to Figure 6 and Figure 8 As shown, along the direction of the second axis Y, the first guide surface 4211 is a plane, the second guide surface 4212 is a plane, the third guide surface 23 is an arc-convex surface, and the fourth guide surface 24 is an arc-convex surface.

[0073] Please refer to the following: Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the carrier 3 includes a base plate 31 and a cover 32 mounted opposite each other, with the cover 32 located on the side closer to the communication body 8. Both the base plate 31 and the cover 32 can be part of the base 9.

[0074] Among them, such as Figure 6 and Figure 7 As shown, a certain accommodating space 30 is formed between the base plate 31 and the cover 32. The shaft portion 41 is located between the base plate 31 and the cover 32. The cover 32 is provided with a through hole 321 (please refer to the reference). Figure 4 and Figure 5As shown), the rotating arm 42 passes through the through hole 321, and the hook portion 421 is located on the side of the cover 32 opposite to the bottom plate 31. Correspondingly, the shaft portion 41 and the reset member 5 can be located within the accommodating space 30 between the bottom plate 31 and the cover 32. Figure 1 and Figure 2 As shown, when the communication body 8 is removed, only a part of the rotating arm 42, including the hook 421, is exposed on the base 9, while the other parts are hidden inside the base 9.

[0075] The purpose of this design is to make the base 9 more aesthetically pleasing overall. In addition, by designing the side of the cover 32 facing the communication body 8, a larger area of ​​the cover 32 can be used to make surface contact with the housing 82 of the communication body 8 when the latch 2 is locked between the limiting members 4, thus supporting the communication body 8 as a whole and making the communication body 8 as a whole stable.

[0076] Optionally, such as Figure 2 , Figure 3 and Figure 4 As shown, the cover 32 has a recessed receiving groove 90, and the through hole 321 is located at the bottom of the receiving groove 90. The shape of the receiving groove 90 corresponds to the outer shape of the housing 82 of the communication body 8, so that a part of the communication body 8 is located in the receiving groove 90.

[0077] In other alternative embodiments, the surface of the cover 32 facing the communication body 8 can be designed in other shapes, as long as it can fit the shape of the housing 82 of the communication body 8 and abut and support the outer surface of the communication body 8.

[0078] The base plate 31 and the cover 32 are detachably connected. For example, the base plate 31 can be mounted on the cover 32 using a second fastener 6 such as bolts. Please refer to [reference needed]. Figure 4 , Figure 5 As shown.

[0079] The dimensions of the base plate 31 and the cover 32 are not particularly limited, as long as they facilitate the assembly of the rotating arm 42, the shaft 41 and the reset piece 5 between them.

[0080] Please see Figure 7 and Figure 8 As shown, in one embodiment, the shaft portion 41 of each limiting member 4 includes a convex shaft 411 protruding relative to both sides of the rotating arm 42 along the first axis X. The shaft hole includes a slot 322 provided on the side of the base plate 31 facing the cover 32 and / or the side of the cover 32 facing the base plate 31, and the convex shaft 411 is disposed in the slot 322. In a specific embodiment, as shown... Figure 7As shown, the slot 322 is provided on the side of the cover 32 facing the bottom plate 31, and the surface of the bottom plate 31 is provided with a support platform 311. The support platform 311 is aligned with the slot 322 so as to restrict the convex shaft 411 while making the shaft portion 41 and the surface of the bottom plate 31 separated by a certain distance.

[0081] In other alternative examples, the slot 322 can also be set separately on the side of the base plate 31 facing the cover 32, as long as the side of the base plate 31 and the cover 32 that are close to each other can limit and accommodate the convex shaft 411. The convex shaft 411 is easier to process and shape on the limiting member 4.

[0082] Please see Figure 6 and Figure 8 As shown, the limiting member 4 also includes a limiting part 43 fixedly connected to the shaft part 41, and the locking module 100 also includes a stop part 33 fixedly connected to the bearing member 3. The stop part 33 can abut against the limiting part 43 to restrict the rotating arm 42 from rotating toward the side closer to the locking part 2. When the stop part 33 abuts against the limiting part 43, the rotating arm 42 is located at its first extreme position.

[0083] That is, the blocking part 33 is used to limit the limiting part 43 from continuing to rotate toward the locking part 2 under the action of the resetting force of the resetting member 5, so that the rotating arm 42 has a first limit position during the rotation process. When the rotating arm 42 is held in this first limit position, there is a suitable distance between the hooks 421, and the first guide surface 4211 and the second guide surface 4212 are held in a position suitable for cooperating with the locking part 2, so that the locking part 2 can be easily locked.

[0084] In some alternative embodiments, the rotating arm 42 has a second extreme position for rotation away from the locking part 2. Since energy is continuously stored in the reset member 5 during the rotation of the rotating arm 42 away from the locking part 2, the second extreme position can be achieved by the action of the reset member 5 on the limiting part 43, without the need for other limiting structures.

[0085] In one embodiment, the abutment 33 includes a portion of the cover 32 located on one side of the through hole 321, and the limiting portion 43 is capable of abutting against the inner surface of the cover 32 facing the base plate 31. In other words, the abutment 33 can also be a portion of the base 9.

[0086] Specifically, please refer to the following: Figure 6 , Figure 8 and Figure 9 As shown, in the direction perpendicular to the second axis Y, the limiting part 43 is provided on the side of the rotating arm 42 opposite to its hook part 421. That is, when the hook part 421 faces the second axis Y, the limiting part 43 is away from the second axis Y (and vice versa; please refer to the reference). Figure 11(As shown). The purpose of this arrangement is that the limiting part 43 is far away from the hook part 421 and the locking part 2, so as not to affect the locking cooperation between the hook part 421 and the locking part 2. Furthermore, the shape and position of the limiting part 43 can have greater design flexibility.

[0087] The angle between the limiting part 43 and the rotating arm 42 can be approximately 90°, for example, 70°~110°, or optionally 80°~100°. Specifically, the angle between the limiting part 43 and the rotating arm 42 is approximately 90°. The purpose of this arrangement is that when the rotating arm 42 is in the first extreme position, that is, when it is approximately parallel to the second axis Y, the limiting part 43 is approximately perpendicular to the second axis Y. At this time, the surface of the abutment part 33 is approximately perpendicular to the second axis Y. For the base 9 and the cover 32, such a surface is easier to set and manufacture.

[0088] Next, we will introduce reset component 5.

[0089] In one embodiment, the reset member 5 is an elastic member that stores a portion of its deformation as the abutment portions 33 rotate away from each other, thereby providing a restoring force for the opposing rotation of the rotating arms 42. Specifically, the reset member 5 can be a spring or a component made of an elastic material.

[0090] In one alternative embodiment, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the reset component 5 can be a torsion spring, and the spring coil of the torsion spring can be sleeved on the convex shaft 411 of the limiting component 4. The two torsion arms are located between the rotating arm 42 and the bearing component 3. Specifically, the two torsion arms can be located between the limiting part 43 and the bottom plate 31 of the bearing component 3. The surface of the bottom plate 31 of the bearing component 3 serves as a support for one of the torsion arms, so that the other torsion arm can push the rotating arm 42 and the limiting part 43 to rotate. Furthermore, since the torsion arm is located between the limiting part 43 and the bearing component 3, the torsion arm does not need to directly contact the rotating arm 42, which makes it easier to design the shape and size of the rotating arm 42 and avoids the torsion spring interfering with the cooperation between the hook part 421 and the locking part 2. In addition, compared with the rotating arm 42, the position and shape of the limiting part 43 can be designed more flexibly. The torsion arm is located between the limiting part 43 and the bearing component 3, which also has a greater space for flexible design and operation and assembly.

[0091] In one alternative embodiment, please refer to Figure 5As shown, the reset element 5 is a compression spring, which is disposed between the rotating arm 42 and the bearing element 3. Specifically, the compression spring can be located between the limiting part 43 and the base plate 31 of the bearing element 3. The surface of the base plate 31 serves as a support for one end of the compression spring, and the other end of the compression spring is used to push the limiting part 43 to rotate. The purpose of this arrangement is to simplify the assembly of the compression spring between the limiting part 43 and the base plate 31, and to reduce the shape requirements of the limiting element 4. For example, the shaft part 41 does not need to include the convex shaft 411.

[0092] In an optional embodiment, the reset member 5 can also be a tension spring, which is disposed between the support member 3 and the rotating arm 42, specifically, between the surface of the cover 32 facing the bottom plate 31 and the limiting part 43. The support member 3 serves as a support for one end of the tension spring, and the other end of the tension spring is used to pull the limiting part 43 to rotate.

[0093] In one embodiment, the reset member 5 can also be a pair of mutually repulsive permanent magnets (not shown), with one permanent magnet disposed on the support member 3 and the other permanent magnet disposed on the limiting part 43 or the rotating arm 42, specifically disposed on the limiting part 43. During the rotation of the rotating arm 42, the two permanent magnets gradually approach each other and generate mutually repulsive magnetic forces.

[0094] Please see Figure 6 , Figure 8 , Figure 9 As shown, in one embodiment, in a direction perpendicular to the second axis Y, the shaft portion 41 is positioned closer to the locking portion 2 than the hook portion 421. The purpose of this arrangement is, as described in [reference needed] Figure 9 As shown, when the third guide surface 23 of the locking part 2 acts on the second guide surface 4212 of the hook part 421, the direction of the generated force F is inclined towards the limiting part 43 in a direction away from the second axis Y, while the line L' connecting the first axis X and the point of application of force F is inclined away from the limiting part 43 in a direction away from the second axis Y. Therefore, there is a large angle between the connecting line L' and the direction of force F, and the lever arm L is large. In some cases, through the design of the shape and size of the shaft part 41, the rotating arm 42, and the hook part 421, the lever arm L can be made to be approximately close to the connecting line L', or even equal to L'. Thus, when the user holds the locking part 2 and moves it along the second axis Y, only a small force is needed to effectively push the rotating arm 42 and its hook part 421 to rotate outward. That is, the locking operation of the locking module 100 is relatively simple.

[0095] The communication device 200 provided in this application embodiment can be a wired communication device, such as... Figure 1 , Figure 2 and Figure 3As shown, the communication unit 8 is connected to the communication control center (not shown) via cable 81 and interacts with the communication control center. Additionally, the communication unit 8 can be connected to an external control power supply via cable 81. In this case, no circuit structure is required on the base 9; only the locking module 100 is needed on the base 9 to physically lock the communication unit 8.

[0096] Depending on the dimensions of the communication unit 8, one or more locking modules 100 can be installed on the base 9 to ensure effective and stable locking of the communication unit 8. For example, please refer to... Figure 4 and Figure 5 As shown, in one embodiment, the communication device 200 includes two locking modules 100.

[0097] The support component 3 of both locking modules 100 can be part of the base 9.

[0098] Further, please refer to Figure 2 and Figure 3 As shown, the two locking modules 100 correspond to two locking parts 2. One locking part 2 is located at the bottom of the communication body 8, that is, on the side surface facing the base 9. For the other locking part 2, since the outer surface of the wiring 81 is generally curved, a portion of the wiring 81 can replace the locking part 2. Of course, in other optional embodiments, the two locking parts 2 can be arranged at intervals on the side surface of the housing 82 of the communication body 8 facing the base 9.

[0099] The communication device 200 provided in this embodiment can be a wireless communication device. The communication body 8 has a built-in wireless communication module (not shown) for wireless communication connection with a communication control center. Furthermore, a battery can be installed inside the communication body 8 to power its internal working module, including the wireless communication device 200. A charging module can be installed inside the base 9 to charge the battery of the communication body 8. Specifically, the charging module can be a wireless charging module or a wired charging module. One or more locking parts 2 can be provided on the surface of the housing 82 of the communication body 8 facing the base 9.

[0100] Furthermore, it should be noted that the locking module 100 is not limited to the communication device 200 described above, but can also be used in any other field where it is necessary to detachably lock two components. The carrier 3 can be at least a part of one of the components, and the locking part 2 can be at least a part of the other component.

[0101] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
