[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

The terms "first" and "second" are only used for the convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0048] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0049] See also Figure 1 , Figure 3 and Figure 4 As shown, the embodiment of the present application provides a communication device 200, which includes a communication body 8, a base 9, and at least one locking module 100, wherein a portion of the locking module 100 is disposed on the base 9, and another portion is disposed on the communication body 8, and the locking module 100 is used to detachably mount the communication body 8 on the base 9. The base 9 is used to be fixedly mounted at a working position, such as a wall or a table top of a workbench.

[0050] Please refer to Figure 4 , Figure 5 and Figure 6 As shown, the lock module 100 includes a bearing member 3, a plurality of stoppers 4, a lock portion 2 and a reset member 5. Specifically, the bearing member 3 is used to be fixedly arranged on the base 9, and each stopper 4 includes a shaft portion 41 and a rotating arm 42 connected to each other. Figure 7 and Figure 8 As shown, each shaft portion 41 is rotatably mounted on the carrier 3 around its own central axis (defined as each first axis X); the locking portion 2 is fixedly connected to the shell 82 of the communication body 8; the reset member 5 is provided on the carrier 3, and is used to provide a restoring force to the rotating arm 42 to rotate toward the locking portion 2; the locking portion 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, Figure 6 , Figure 7 and Figure 8 As shown, the end of the rotating arm 42 away from the shaft portion 41 is provided with a hook portion 421, and the hook portion 421 has a first guide surface 4211 and a second guide surface 4212. Fig. 9 and Fig.10 As shown, the first guide surface 4211 and the second guide surface 4212 gradually expand outwardly to each other in the direction away from the locking portion 2, and the first guide surface 4211 is located on the side of the hook portion 421 facing the shaft portion 41, and the second guide surface 4212 is located on the side of the hook portion 421 away from the shaft portion 41; the locking portion 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 portion 2 facing the shaft portion 41, and the fourth guide surface 24 is located on the side of the locking portion 2 away from the shaft portion 41, and the third guide surface 23 and the fourth guide surface 24 are gradually retracted to each other in the direction toward the hook portion 421; the second guide surface 4212 is used for sliding cooperation with the third guide surface 23, and the first guide surface 4211 is used for sliding cooperation with the fourth guide surface 24. That is, the first guide surface 4211 and the second guide surface 4212 have a certain angle relative to the first axis X and the second axis Y, so that they are relatively expanded, and the third guide surface 23 and the fourth guide surface 24 have a certain angle relative to the first axis X and the second axis Y, so that they are relatively contracted.

[0052] When the locking part 2 needs to be locked on the rotating arm 42, the user holds the locking part 2 and moves the locking part 2 along the second axis Y toward the base 9 ( Fig. 9 and Fig.10 The straight solid arrow in the figure indicates the direction of movement), see Fig. 9 and Fig.10As shown, the third guide surface 23 of the locking portion 2 slides relative to the second guide surface 4212 of the hook portion 421. During the sliding process, the locking portion 2 gradually approaches the shaft portion 41 along the second axis Y and pushes the hook portion 421 to rotate in a direction away from the locking portion 2 ( Fig. 9 and Fig.10 The solid arrow in the arc line in the figure indicates the rotation direction). During this process, energy is stored in the reset member 5. When the lock portion 2 continues to move along the second axis Y and passes over the second guide surface 4212, the reset member 5 provides a reset force to the rotating arm 42, and the rotating arm 42 automatically rotates toward the lock portion 2, so that the fourth guide surface 24 abuts against the first guide surface 4211. Please refer to Figure 6 and Fig.10 As shown, at this time, the locking portion 2 is restricted by the hook portion 421 to the side facing the shaft portion 41 , and the locking portion 2 cannot be separated from the hook portion 421 on the square of the second axis Y. In this way, the locking portion 2 is locked on the rotating arm 42 .

[0053] Conversely, when the lock part 2 needs to be disassembled from the rotating arm 42, the user holds the lock part 2 and moves the lock part 2 away from the base 9 along the second axis Y, and the fourth guide surface 24 of the lock part 2 slides relative to the first guide surface 4211 of the hook part 421. During the sliding process, the lock part 2 gradually moves away from the shaft 41 and pushes the hook part 421 to rotate in the direction away from the lock part 2. In this process, since the rotating arm 42 rotates relatively away from the lock part 2, energy is stored in the reset member 5; when the lock part 2 continues to move along the second axis Y and passes over the first guide surface 4211, the rotating arm 42 automatically rotates toward the lock part 2 and returns to the initial position by the reset force provided by the reset member 5 to the rotating arm 42. In this way, the lock part 2 is separated from the rotating arm 42 and unlocked.

[0054] In the above locking and unlocking process, the force applied by the user to the locking portion 2 is substantially along the second axis Y, that is, substantially in the direction from the communication body 8 to the base 9 and the bearing member 3 .

[0055] The communication device 200 and its locking module 100 provided in the embodiment of the present application can realize installation and removal of the locking portion 2 in a direction vertical or substantially vertical to the supporting member 3 by means of the cooperation of the third guide surface 23 and the fourth guide surface 24 of the locking portion 2 and the first guide surface 4211 and the second guide surface 4212 of the hook portion 421. When the user uses the locking module 100 and the communication body 8, the force applied to the communication body 8 is vertical or substantially vertical to the base 9, which conforms to the user's operating habits and force application habits, and the user has a good experience. Moreover, compared with the solution in the prior art in which the buckle is against the side of the intercom body, the hook portion 421 limits the locking portion 2 in the picking direction and the placing direction of the communication body 8, so that the installation of the communication body 8 is more stable. Even if the side, bottom or top surface of the communication device 200 is subjected to impact force, the locking portion 2 is not easy to separate from the hook portion 421.

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

[0057] Similarly, the lock part 2 is fixedly connected to the communication body 8, which includes that the lock part 2 can be integrally formed with the shell 82 of the communication body 8, or separately formed and connected together, or the lock part 2 can be a part of the shell 82. Figure 2 , Figure 3 and Figure 6 As shown, in the embodiment of the present application, the locking portion 2 is fixed to the shell 82 of the communication body 8 by a first fastener (not shown). For example, the locking portion 2 is detachably connected to the shell 82 of the communication body 8 by bolts or the like, or the locking portion 2 is non-detachably mounted on the shell 82 of the communication body 8 by welding or the like.

[0058] In each locking module 100, there are multiple limit members 4, and the multiple limit members 4 can be optionally distributed at intervals in a plane perpendicular to the second axis Y to limit 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 shape 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 more optional embodiments, the number of rotating arms 42 can be three, four or more, which can be designed according to specific needs.

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

[0061] like Figure 6 , Fig. 9 and Fig.10 As shown, the number of the limiting members 4 is two, and the two first axes X are parallel to each other. When the number of the limiting members 4 is three, the three first axes X may be arranged at an angle of 120° to each other.

[0062] The plurality of stoppers 4 are respectively matched with a part of the lock part 2. The lock part 2 can be located between the plurality of stoppers 4. Accordingly, the hook part 421 is arranged on the side close to each other of the rotating arm 42. Figure 6 , Fig. 9 and Fig.10 shown.

[0063] Alternatively, see Fig.11 As shown, the locking portion 2 is arranged around a plurality of limiting members 4 , and the hook portion 421 is arranged on the side of the rotating arm 42 that are away from each other.

[0064] The embodiment of the present application is mainly described by taking the locking portion 2 being located between a plurality of stoppers 4 as an example. The second axis Y can be arranged to pass through the locking portion 2, and the plurality of stoppers 4 are evenly distributed around the second axis Y.

[0065] The shaft portion 41 in the stopper 4 is used to form a rotational fit with the carrier 3, so the form of the shaft portion 41 is not limited. Figure 6 , Figure 7 and Figure 8 As shown, the shaft portion 41 may include a protruding shaft 411 protruding relative to the rotating arm 42 along the first axis X, and the protruding shaft 411 is used to cooperate with the shaft hole on the bearing 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, and the shaft hole is used to cooperate with the protruding shaft structure on the bearing member 3.

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

[0067] Accordingly, if Figure 8 As shown, in the direction around the second axis Y, the first guide surface 4211 and the second guide surface 4212 are both arc surfaces. Optionally, in the direction around the second axis Y, the first guide surface 4211 and the second guide surface 4212 are both arc surfaces. In other words, when the first guide surface 4211 and the second guide surface 4212 are cut with a plane perpendicular to the second axis Y, the intersection line obtained is an arc.

[0068] In other optional embodiments, the locking portion 2 may be polygonal, for example, quadrilateral or even square, in the direction along the second axis Y. Accordingly, the hook portion 421 may be formed and arranged corresponding to the edge of the locking portion 2. This is not particularly limited 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 arc convex surfaces or plane surfaces, and the first guide surface 4211 and the second guide surface 4212 are both plane surfaces or arc convex surfaces. Figure 5 From the cross-sectional view shown, or in other words, the intersection lines obtained by cutting the locking portion 2 and the hook portion 421 with a plane passing through the second axis Y are all straight lines or convex lines. The purpose of this arrangement is to facilitate the processing and manufacturing of the locking portion 2 and the limiting member 4.

[0070] In one embodiment, see Figure 6 , Figure 8 and Fig.10As shown, in the direction along the second axis Y, one of the fourth guide surface 24 and the first guide surface 4211 is an arc convex surface, and the other is a plane. That is, when the fourth guide surface 24 of the lock buckle 2 and the first guide surface 4211 of the hook 421 are cut with a plane passing through the second axis Y, one of the two intersection lines is an arc convex line, and the other is a straight line. The purpose of this arrangement is that during the movement of the lock buckle 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 around the second axis Y), which is conducive to reducing the friction between the first guide surface 4211 and the fourth guide surface 24, making it easier for users to operate and lock the lock buckle 2.

[0071] In one embodiment, see Figure 6 , Figure 8 and Fig.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 an arc convex surface, and the other is a plane. That is, when the third guide surface 23 of the locking part 2 and the second guide surface 4212 of the hook part 421 are cut with a plane passing through the second axis Y, one of the two intersection lines is an arc convex line, and the other is a straight line. The purpose of this arrangement is that when the locking part 2 moves 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 around the second axis Y), which is also conducive to reducing the friction between the second guide surface 4212 and the third guide surface 23, making it easier for users to disassemble the locking part 2.

[0072] In a specific embodiment of the present application, please refer to Figure 6 and Figure 8 As shown, in the direction along 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 Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the bearing member 3 comprises a bottom plate 31 and a cover 32 which are installed opposite to each other, and the cover 32 is arranged on a side close to the communication body 8. Both the bottom plate 31 and the cover 32 can be a part of the base 9.

[0074] Among them, Figure 6 and Figure 7 As shown, a certain accommodation space 30 is formed between the bottom plate 31 and the cover body 32, the shaft portion 41 is located between the bottom plate 31 and the cover body 32, and the cover body 32 is provided with a through hole 321 (please refer to 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 body 32 away from the bottom plate 31. Accordingly, the shaft portion 41 and the reset member 5 can be located in the accommodating space 30 between the bottom plate 31 and the cover body 32. Figure 1 and Figure 2 As shown, after the communication body 8 is taken, only a portion of the rotating arm 42 including the hook portion 421 is exposed from the base 9 , and the other portions are hidden inside the base 9 .

[0075] The purpose of such a configuration is to make the base 9 more beautiful as a whole. In addition, by designing the surface of the cover 32 on one side facing the communication body 8, when the locking portion 2 is locked between the limit members 4, a larger area on the cover 32 is used to achieve surface contact with the shell 82 of the communication body 8, thereby supporting the communication body 8 as a whole and making the communication body 8 as a whole stable.

[0076] Alternatively, if Figure 2 , Figure 3 and Figure 4 As shown, the cover 32 is provided with 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 shape of the shell 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 optional embodiments, the surface of the cover 32 facing the communication body 8 can be designed to be other shapes, as long as it can adapt to the shape of the shell 82 of the communication body 8 and abut and support the outer surface of the communication body 8.

[0078] The bottom plate 31 and the cover body 32 are detachably connected. For example, the bottom plate 31 can be set on the cover body 32 by a second fastener 6 such as a bolt. Figure 4 , Figure 5 shown.

[0079] The size of the bottom plate 31 and the cover body 32 is not particularly limited, as long as it is convenient for assembling the rotating arm 42, the shaft 41 and the reset member 5 therebetween.

[0080] See also Figure 7 and Figure 8 As shown, in one embodiment, the shaft portion 41 of each stopper 4 includes a convex shaft 411 protruding along the first axis X relative to both sides of the rotating arm 42, and the shaft hole includes a slot hole 322 arranged on the side of the bottom plate 31 facing the cover body 32 and / or the side of the cover body 32 facing the bottom plate 31, and the convex shaft 411 is arranged in the slot hole 322. In a specific embodiment, as Figure 7As shown, the slot hole 322 is arranged on the side of the cover body 32 facing the bottom plate 31, and a support platform 311 is protruded from the surface of the bottom plate 31, and the support platform 311 is aligned with the slot hole 322 to limit the protruding shaft 411 while keeping the shaft portion 41 a certain distance away from the surface of the bottom plate 31.

[0081] In other optional embodiments, the slot 322 may be disposed on the side of the bottom plate 31 facing the cover 32, as long as the sides of the bottom plate 31 and the cover 32 that are close to each other can limit and accommodate the convex shaft 411. On the limiter 4, the convex shaft 411 is easier to process and shape.

[0082] See also Figure 6 and Figure 8 As shown, the limiting member 4 further includes a limiting portion 43 fixedly connected to the shaft portion 41, and the locking module 100 further includes a resisting portion 33 fixedly connected to the bearing member 3, and the resisting portion 33 can abut against the limiting portion 43 to limit the rotation of the rotating arm 42 toward the side close to the locking portion 2. When the resisting portion 33 abuts against the limiting portion 43, the rotating arm 42 is located at its first extreme position.

[0083] That is, the stopper 33 is used to limit the limiter 43 from continuing to rotate toward the lock part 2 under the action of the reset force of the reset member 5, so that the rotating arm 42 has a first limit position during the rotation process. When the rotating arm 42 is maintained at the 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 maintained at a position suitable for cooperating with the lock part 2, so that the lock part 2 can be easily locked.

[0084] In some optional embodiments, the rotating arm 42 has a second limit position of rotating away from the locking portion 2. Since the resetting member 5 continuously stores energy during the rotating arm 42 rotating away from the locking portion 2, the second limit position can be achieved by the action of the resetting member 5 on the limiting portion 43 without providing other limiting structures.

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

[0086] For details, please refer to Figure 6 , Figure 8 and Fig. 9 As shown, in the direction perpendicular to the second axis Y, the limiting portion 43 is disposed on the side of the rotating arm 42 away from the hook portion 421 thereof, that is, when the hook portion 421 faces the second axis Y, the limiting portion 43 faces away from the second axis Y (vice versa, please refer to Fig.11The purpose of such a configuration is that the limiting portion 43 is away from the hook portion 421 and the locking portion 2, which will not affect the locking cooperation between the hook portion 421 and the locking portion 2. Furthermore, the shape and position of the limiting portion 43 can have a larger flexible design space.

[0087] The angle between the limit portion 43 and the rotating arm 42 can be approximately 90°, for example, 70° to 110°, and optionally, 80° to 100°. Specifically, the angle between the limit portion 43 and the rotating arm 42 is approximately 90°. The purpose of such a setting is that when the rotating arm 42 is located at the first extreme position, that is, when it is substantially parallel to the second axis Y, the limit portion 43 is substantially perpendicular to the second axis Y. At this time, the surface of the stop portion 33 is substantially perpendicular to the second axis Y. For the base 9 and the cover body 32, such a surface is easier to set and process.

[0088] Next, the reset member 5 will be described.

[0089] In one embodiment, the reset member 5 is an elastic member, which stores a portion of the deformation during the process of the resisting parts 33 rotating away from each other, thereby providing a restoring force for the rotating arms 42 to rotate toward each other. Specifically, the reset member 5 can be a spring or an elastic material member.

[0090] In an optional embodiment, if Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the reset member 5 can be a torsion spring, the spring coil of which can be sleeved on the convex shaft 411 of the limiting member 4, and the two torsion arms are located between the rotating arm 42 and the supporting member 3. Specifically, the two torsion arms can be located between the limiting portion 43 and the bottom plate 31 of the supporting member 3, and the surface of the bottom plate 31 of the supporting member 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 portion 43 to rotate; and, the torsion arm is located between the limiting portion 43 and the supporting member 3, and the torsion arm does not need to directly contact the rotating arm 42, which is more convenient for the shape and size design of the rotating arm 42, and avoids the torsion spring from interfering with the cooperation between the hook portion 421 and the locking portion 2; in addition, compared with the rotating arm 42, the position and shape of the limiting portion 43 can be designed more flexibly, and the torsion arm is located between the limiting portion 43 and the supporting member 3, which also has a larger flexible design space and operation and assembly space.

[0091] In an alternative embodiment, see Figure 5As shown, the reset member 5 is a compression spring, which is arranged between the rotating arm 42 and the bearing member 3. Specifically, the compression spring can be located between the limiting portion 43 and the bottom plate 31 of the bearing member 3. The surface of the bottom 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 portion 43 to rotate. The purpose of such a setting is that the assembly of the compression spring between the limiting portion 43 and the bottom plate 31 is simpler, and the shape of the limiting member 4 is less required. For example, the shaft portion 41 does not need to include the convex shaft 411 at this time.

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

[0093] In one embodiment, the reset member 5 may also be a pair of mutually repelling permanent magnets (not shown), one permanent magnet being disposed on the bearing member 3, and the other permanent magnet being disposed on the limit portion 43 or the rotating arm 42, specifically, being disposed on the limit portion 43. During the rotation of the rotating arm 42, the two permanent magnets gradually approach each other and generate mutually repelling magnetic forces.

[0094] See also Figure 6 , Figure 8 , Fig. 9 As shown, in one embodiment, in a direction perpendicular to the second axis Y, the shaft portion 41 is arranged closer to the locking portion 2 than the hook portion 421. The purpose of this arrangement is to refer to Fig. 9 As shown, when the third guide surface 23 of the lock part 2 acts on the second guide surface 4212 of the hook part 421, the direction of the generated force F is inclined toward the limiting part 43 in the direction away from the second axis Y, and at this time, the line L' between the first axis X and the point of action of the force F is inclined away from the limiting part 43 in the direction away from the second axis Y. Therefore, there is a large angle between the line L' and the direction of the force F, and at this time, the lever arm L is large. In some cases, through the shape and size design of the shaft 41, the rotating arm 42, and the hook part 421, it can be achieved that the lever arm L is roughly close to the connecting line L', or even the lever arm L is equal to L'. In this way, when the user holds the lock part 2 and moves along the second axis Y, only a small force needs to be applied to effectively push the rotating arm 42 and its hook part 421 to rotate outward. That is, the locking operation of the lock module 100 is relatively simple.

[0095] The communication device 200 provided in the embodiment of the present application may be a wired communication device, such as Figure 1 , Figure 2 and Figure 3As shown, the communication body 8 is connected to the communication control center (not shown) through the wiring 81, and exchanges information with the communication control center. In addition, the communication body 8 can be connected to an external control power supply through the wiring 81. At this time, there is no need to set a circuit structure on the base 9, and only a lock module 100 is set on the base 9 to physically lock the communication body 8.

[0096] According to the size of the communication body 8, one or more locking modules 100 may be provided on the base 9 to ensure that the communication body 8 can be locked effectively and stably. Figure 4 and Figure 5 As shown, in one embodiment, the communication device 200 includes two locking modules 100 .

[0097] The supporting components 3 of the two locking modules 100 can both be part of the base 9 .

[0098] For further information, see Figure 2 and Figure 3 As shown, two locking modules 100 correspond to two locking parts 2, one of which is disposed at the bottom of the communication body 8, that is, on one side of the surface facing the base 9, and for the other locking part 2, since the outer surface of the wiring 81 is generally an arc surface, a part of the wiring 81 can replace the locking part 2. Of course, in other optional embodiments, the two locking parts 2 can be disposed at intervals on one side of the housing 82 of the communication body 8 facing the base 9.

[0099] The communication device 200 provided in the embodiment of the present application may be a wireless communication device. The communication body 8 has a built-in wireless communication module (not shown) to establish a wireless communication connection with the communication control center. In addition, a battery may be provided in the communication body 8 to power the working module including the wireless communication device 200 therein. At this time, a charging module may be provided in the base 9 to charge the battery of the communication body 8. The charging module may specifically be a wireless charging module or a wired charging module. At this time, one or more locking portions 2 may be provided on a side surface of the shell 82 of the communication body 8 facing the base 9.

[0100] In addition, it should be noted that the locking module 100 is not limited to being used in the above-mentioned communication device 200, but can also be used in any other field where two components need to be detachably locked, 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 only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
