Description

Technical Field

[0001] This application relates to the field of mobile terminal accessories technology, and in particular to a lanyard assembly for a mobile terminal and a mobile terminal assembly. Background Technology

[0002] Smartwatches, as mobile devices for children, are generally only worn on the wrist, resulting in limited usage scenarios. To meet the needs of more diverse scenarios, users now typically wear the watch around their neck using a lanyard. However, current lanyard options are either fixed in length or, while the length is adjustable, the complex structure of the lanyard makes adjustment difficult and inconvenient. Utility Model Content

[0003] To address the aforementioned problems, this application provides a lanyard assembly for a mobile terminal and a mobile terminal assembly. The lanyard assembly is ingeniously designed, has a simple structure, and the lanyard length is easily adjustable. The technical solution adopted in this application is as follows:

[0004] A lanyard assembly for a mobile terminal includes: a first lanyard, a second lanyard, a roller, and a locking member; the locking member includes a pressing portion and a plugging portion, the plugging portion being rotatably connected to the roller and exposed at both ends of the roller, the pressing portion being located outside the roller, and both ends of the pressing portion being respectively connected to the portions of the plugging portion exposed at both ends of the roller; the opposite ends of the first lanyard are respectively connected to the portions of the plugging portion exposed at both ends of the roller; the opposite ends of the second lanyard are respectively fixed to the sidewall of the roller, and when the roller is rotated, the second lanyard is wound around the roller or released from the roller;

[0005] In the locked state, the minimum distance between the pressing part and the side wall of the roller is less than the diameter of the second hanging rope, and the second hanging rope is clamped between the pressing part and the side wall of the roller to restrict the relative rotation of the insertion part and the roller.

[0006] In the unlocked state, the minimum distance between the squeezing part and the side wall of the roller is not less than the diameter of the second hanging rope, and the insertion part and the roller can rotate relative to each other.

[0007] This application features a simple structure, an attractive appearance, and easily adjustable rope length. By controlling the distance between the extrusion part and the roller sidewall, when the minimum distance between them is less than the diameter of the second rope, the second rope is clamped between them. In this case, the roller cannot rotate relative to the locking element, meaning the rope assembly is locked and its length is fixed. When the minimum distance between them is not less than the diameter of the second rope, the extrusion part and roller sidewall cannot compress the second rope, allowing the roller to rotate relative to the locking element. In this case, the rope assembly is unlocked, and the length of the second rope wound on the roller can change with the rotation of the roller, thus altering the length of the rope assembly.

[0008] In some embodiments, the distance between the extrusion part and the sidewall of the roller gradually increases or decreases along the length of the roller; the insertion part can move relative to the roller along the axial direction of the roller so that the minimum distance between the extrusion part and the sidewall of the roller is less than or not less than the diameter of the second hanging rope.

[0009] By gradually increasing or decreasing the distance between the pressing part and the roller sidewall along the length of the roller, the minimum distance between the pressing part and the roller sidewall increases or decreases when the insertion part, or the locking part, is moved along the axial direction of the roller. This allows the second hanging rope to switch between a non-pressing state (where the pressing part and the roller sidewall do not clamp the second hanging rope) and a pressing state (where the pressing part and the roller sidewall clamp the second hanging rope). This, in turn, allows the hanging rope assembly to switch between an unlocked state and a locked state. The state switching is convenient and easy to operate.

[0010] In some embodiments, the opposite ends of the first hanging rope are rotatably connected to the portions of the plug portion exposed at both ends of the roller.

[0011] By rotatably connecting the two ends of the first hanging rope to the plug, compared to fixing the two ends of the first hanging rope to the plug, the risk of damage to the connection between the first hanging rope and the plug can be reduced, and the hanging rope assembly can be made easier to store.

[0012] In some embodiments, the two connection points between the first hanging rope and the plug are both located between the two connection points between the squeezing part and the plug.

[0013] By placing the two connecting parts of the first hanging rope and the plug-in part between the two connecting parts of the pressing part and the plug-in part, the two connecting parts of the pressing part and the plug-in part block the two connecting parts of the first hanging rope and the plug-in part, thus preventing the two opposite ends of the first hanging rope from falling outward from the plug-in part. There is no need to set up other structures separately to prevent the first hanging rope from falling outward from the plug-in part.

[0014] In some embodiments, each end of the first hanging rope is provided with a rotating part, the rotating part is provided with a through hole, and the insertion part is inserted into the through hole.

[0015] In some embodiments, the plug-in portion includes a first plug-in section and a second plug-in section, the first plug-in section and the second plug-in section are separately disposed, and both ends of the roller are provided with plug holes, the first plug-in section and the second plug-in section are respectively inserted into the corresponding plug holes.

[0016] In some embodiments, the insertion holes at both ends of the roller are interconnected to form a through hole in the roller.

[0017] By setting the plug-in portion as a first plug-in segment and a second plug-in segment that are separate from each other, and setting the plug hole as a through hole, the material used for the plug-in portion and the roller can be saved, and the total weight of the roller and the locking part can be reduced.

[0018] In some embodiments, the socket is a blind socket.

[0019] On the other hand, this application provides a mobile terminal component, including a mobile terminal and the aforementioned lanyard component, wherein the second lanyard is connected to the mobile terminal.

[0020] In some implementations, the mobile terminal is a watch host.

[0021] The lanyard assembly and mobile terminal assembly provided in this application have at least one of the following beneficial effects:

[0022] 1. This application provides a lanyard assembly for a mobile terminal, which has a simple structure, an attractive appearance, and an easily adjustable lanyard length. By controlling the distance between the squeezing part and the side wall of the roller, when the minimum distance between the squeezing part and the side wall of the roller is less than the diameter of the second lanyard, the second lanyard is clamped between the squeezing part and the side wall of the roller. At this time, the roller cannot rotate relative to the locking member, that is, the lanyard assembly is in a locked state, and the length of the lanyard assembly is fixed. When the minimum distance between the squeezing part and the side wall of the roller is not less than the diameter of the second lanyard, the squeezing part and the side wall of the roller cannot squeeze the second lanyard. At this time, the roller can rotate relative to the locking member, that is, the lanyard assembly is in an unlocked state, and the length of the second lanyard wound on the roller can change with the rotation of the roller, thereby changing the length of the lanyard assembly.

[0023] 2. The lanyard assembly for a mobile terminal provided in this application gradually increases or decreases the distance between the squeezing part and the side wall of the roller along the length of the roller. When the insertion part, or the locking part, is moved along the axial direction of the roller, the minimum distance between the squeezing part and the side wall of the roller increases or decreases, thereby switching the second lanyard between a non-squeezed state (the squeezing part and the side wall of the roller do not clamp the second lanyard) and a squeezing state (the squeezing part and the side wall of the roller clamp the second lanyard). This allows the lanyard assembly to switch between an unlocked state and a locked state, making the state switching convenient and easy to operate.

[0024] 3. The lanyard assembly for a mobile terminal provided in this application rotatably connects the two opposite ends of the first lanyard to the plug-in part. Compared with the opposite ends of the first lanyard being fixedly connected to the plug-in part, this reduces the risk of damage at the connection between the first lanyard and the plug-in part, and makes the lanyard assembly easier to store.

[0025] 4. The lanyard assembly for a mobile terminal provided in this application, by placing the two connecting parts of the first lanyard and the plug-in part between the two connecting parts of the compression part and the plug-in part, the two connecting parts of the compression part and the plug-in part form a block against the two connecting parts of the first lanyard and the plug-in part, which can prevent the opposite ends of the first lanyard from falling outward from the plug-in part, without the need to set up other structures separately to prevent the first lanyard from falling outward from the plug-in part.

[0026] 5. The lanyard assembly for mobile terminals provided in this application saves material for the plug and roller by setting the plug part as a first plug segment and a second plug segment that are separate from each other, and setting the plug hole as a through hole. The total weight of the roller and locking part is reduced. Attached Figure Description

[0037] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0038] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0039] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0040] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0042] refer to Figures 1-7 This application provides a lanyard assembly for a mobile terminal, including: a first lanyard 1, a second lanyard 2, a roller 3, and a locking member 4; the locking member 4 includes a pressing part 41 and a plugging part 42, the plugging part 42 is rotatably connected to the roller 3 and exposed at both ends of the roller 3, the pressing part 41 is located outside the roller 3, and the two ends of the pressing part 41 are respectively connected to the portions of the plugging part 42 exposed at both ends of the roller 3; the opposite ends of the first lanyard 1 are respectively connected to the portions of the plugging part 42 exposed at both ends of the roller 3; the opposite ends of the second lanyard 2 are respectively fixed to the side wall of the roller 3, and when the roller 3 is rotated, the second lanyard 2 is wound around the roller 3 or released from the roller 3;

[0043] In the locked state, the minimum distance between the extrusion part 41 and the side wall of the roller 3 is less than the diameter of the second hanging rope 2. The second hanging rope 2 is clamped between the extrusion part 41 and the side wall of the roller 3 to restrict the relative rotation between the insertion part 42 and the roller 3.

[0044] In the unlocked state, the minimum distance between the squeezing part 41 and the side wall of the roller 3 is not less than the diameter of the second hanging rope 2, and the insertion part 42 and the roller 3 can rotate relative to each other.

[0045] This application features a simple structure, an attractive appearance, and easily adjustable rope length. By controlling the distance between the pressing part 41 and the side wall of the roller 3, when the minimum distance between the pressing part 41 and the side wall of the roller 3 is less than the diameter of the second rope 2, the second rope 2 is clamped between the pressing part 41 and the side wall of the roller 3. At this time, the roller 3 cannot rotate relative to the locking member 4, meaning the rope assembly is in a locked state, and the length of the rope assembly is fixed. When the minimum distance between the pressing part 41 and the side wall of the roller 3 is not less than the diameter of the second rope 2, the pressing part 41 and the side wall of the roller 3 cannot press the second rope 2. At this time, the roller 3 can rotate relative to the locking member 4, meaning the rope assembly is in an unlocked state. The length of the second rope 2 wound on the roller 3 can change with the rotation of the roller 3, thereby changing the length of the rope assembly.

[0046] refer to Figures 1-7 In one embodiment, the distance between the extrusion part 41 and the side wall of the roller 3 gradually increases or decreases along the length direction of the roller 3; the insertion part 42 can move relative to the roller 3 along the axial direction of the roller 3 so that the minimum distance between the extrusion part 41 and the side wall of the roller 3 is less than or not less than the diameter of the second hanging rope 2.

[0047] It is understandable that by gradually increasing or decreasing the distance between the pressing part 41 and the side wall of the roller 3 along the length of the roller 3, when the insertion part 42 is moved along the axial direction of the roller 3, or when the locking part 4 is moved, the minimum distance between the pressing part 41 and the side wall of the roller 3 will increase or decrease. This allows the second hanging rope 2 to switch between a non-pressing state (the pressing part 41 and the side wall of the roller 3 do not clamp the second hanging rope 2) and a pressing state (the pressing part 41 and the side wall of the roller 3 clamp the second hanging rope 2). This allows the hanging rope assembly to switch between an unlocked state and a locked state. The state switching is convenient and easy to operate.

[0048] refer to Figures 2-4 , Figure 6 , Figure 7 In one embodiment, the opposite ends of the first hanging rope 1 are rotatably connected to the portions of the plug portion 42 that are exposed at both ends of the roller 3.

[0049] It is worth noting that by rotatably connecting the two ends of the first hanging rope 1 to the plug part 42, compared to fixing the two ends of the first hanging rope 1 to the plug part 42, on the one hand, the risk of damage to the connection between the first hanging rope 1 and the plug part 42 can be reduced, and on the other hand, the hanging rope assembly can be easily stored.

[0050] refer to Figures 1-7 In one embodiment, the two connection points of the first hanging rope 1 and the plug 42 are both located between the two connection points of the compression part 41 and the plug 42.

[0051] It is worth noting that by placing the two connecting parts of the first hanging rope 1 and the plug-in part 42 between the two connecting parts of the pressing part 41 and the plug-in part 42, the two connecting parts of the pressing part 41 and the plug-in part 42 form a blockage between the two connecting parts of the first hanging rope 1 and the plug-in part 42, which can prevent the opposite ends of the first hanging rope 1 from falling outward from the plug-in part 42. There is no need to set up other structures separately to prevent the first hanging rope 1 from falling outward from the plug-in part 42.

[0052] refer to Figures 2-4 , Figure 6 , Figure 7 In one embodiment, the first hanging rope 1 has a rotating part 11 at each of its opposite ends, and the rotating part 11 has a through hole 111, through which the insertion part 42 passes.

[0053] refer to Figures 2-4 , Figure 6 , Figure 7In one embodiment, the plug-in portion 42 includes a first plug-in segment 421 and a second plug-in segment 422, which are separately disposed. Both ends of the roller 3 are provided with plug holes 31, and the first plug-in segment 421 and the second plug-in segment 422 are respectively inserted into the corresponding plug holes 31.

[0054] Specifically, the insertion hole 31 can be a blind hole or a through hole formed by connecting two insertion holes 31. When two insertion holes 31 are connected to form a through hole, the insertion part 42 does not have to be a separate arrangement of the first insertion segment 421 and the second insertion segment 422; the insertion part 42 can be a typical arrangement that passes through the through hole. It is understood that by setting the insertion part 42 as a separate first insertion segment 421 and second insertion segment 422, and setting the insertion hole 31 as a through hole, the material used for the insertion part 42 and the roller 3 can be saved, and the total weight of the roller 3 and the locking member 4 can be reduced.

[0055] On the other hand, reference Figure 1 , Figure 5 This application provides a mobile terminal component, including a mobile terminal and the aforementioned lanyard assembly, wherein a second lanyard 2 is connected to the mobile terminal. The specific structure of the lanyard assembly is as described in the foregoing embodiments. Since this mobile terminal component adopts the technical solutions of the foregoing embodiments, it at least has the beneficial effects brought about by the technical solutions of the foregoing embodiments, which will not be elaborated further here.

[0056] refer to Figure 1 , Figure 5 In one embodiment, the mobile terminal is the watch host 5. It should be noted that in other embodiments, the mobile terminal may also be a mobile phone, tablet, or walkie-talkie, etc. In this application, only the watch host 5 is used as an example for demonstration.

[0057] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
