Description

Technical Field

[0001] The present invention relates to the technical field of watches, and in particular to a modular watch. Background Art

[0002] A wristwatch is an instrument worn on the wrist to tell time and display the time. Usually, the watch is made of leather, rubber, nylon, stainless steel and other materials to make a strap, and the "head" that displays the time is tied to the wrist. With the development of time, modern watches have added more complex functions such as electronic notebooks, MP3, mobile phones, etc.

[0003] With the development of society, watches, as instruments for timing or displaying time, have become an indispensable tool in people's lives. With the development of science and technology, especially the rapid development of mobile devices such as mobile phones, the timing or displaying function of watches has gradually weakened, but the beauty and image value brought by wearing watches have been greatly improved. Watches have gradually become a daily accessory, and the watches they wear also reflect the image, status and taste of the wearer. Therefore, the development and design of watches pay more and more attention to the changes in their appearance.

[0004] Existing watch designs often adopt an integrated setting, which means that they lack sufficient flexibility in appearance and function, and cannot fully meet users' diverse aesthetic requirements or meet personalized needs in different occasions. Once most watches are made, their appearance, strap color, dial style and other elements are fixed, and users cannot adjust them according to their preferences or the atmosphere of a specific occasion. Such a design limits the applicability and fun of the watch, making it impossible for users to find a watch that perfectly matches their image or environment when facing different styles of activities or clothing. Summary of the invention

[0005] In view of this, the purpose of the present invention is to overcome the deficiencies in the related art, and the present invention provides a modular watch.

[0006] The present invention provides the following technical solutions:

[0007] A modular watch comprises a shell, an inner shell, a bezel and a locking piece.

[0008] The shell is provided with a mounting hole; the inner liner is mounted in the shell; the bezel is arranged in the mounting hole; the locking member is arranged between the shell and the inner liner, and the locking member is used to limit the relative position of the inner liner and the shell; when the bezel is mounted on the shell, the locking member can be driven to lock the relative position of the inner liner and the bezel on the shell.

[0009] As a further improvement of the above technical solution, the locking piece is an elastic piece, a tightening portion is provided on the locking piece on the side facing the mounting hole, and an extrusion end is provided on the end surface of the bezel facing the shell; when the bezel is installed on the shell, the extrusion end can squeeze the locking piece to deform, thereby making the tightening portion approach the mounting hole and press against the outer wall of the inner liner.

[0010] As a further improvement of the above technical solution, a plurality of locking members are evenly distributed relative to the axial circumference of the inner container.

[0011] As a further improvement of the above technical solution, a side surface of the inner container is provided with a concave surface corresponding to the tightening portion.

[0012] As a further improvement of the above technical solution, a docking groove corresponding to the extrusion end is provided on the end surface of the shell close to the bezel, a tightening hole connected to the mounting hole is provided on the inner wall of the docking groove adjacent to the mounting hole, the locking piece is arranged in the docking groove, and the tightening portion is located in the tightening hole.

[0013] As a further improvement of the above technical solution, the docking groove is an annular groove, and the axis of the docking groove coincides with the axis of the inner liner; a limiting groove is provided on the inner side wall of the docking groove away from the inner liner, and a locking boss corresponding to the limiting groove is provided on the extrusion end, and the locking boss is passed through the limiting groove to limit the relative position of the bezel and the shell.

[0014] As a further improvement of the above technical solution, a plurality of the limiting grooves are evenly distributed relative to the axial circumference of the inner container.

[0015] As a further improvement of the above technical solution, the limiting groove consists of a vertical groove and a horizontal groove. The opening direction of the vertical groove is parallel to the axis of the inner liner, and the opening direction of the horizontal groove is perpendicular to the axis of the inner liner. The vertical groove extends toward the end face of the shell close to the bezel to form an opening, and the end of the vertical groove away from the bezel is connected to the horizontal groove.

[0016] As a further improvement of the above technical solution, the inner side wall of the transverse groove close to the bezel has a recessed portion.

[0017] As a further improvement of the above technical solution, a first limiting step is provided on the end side wall of the inner liner close to the bezel, and a second limiting step corresponding to the first limiting step is provided on the inner side wall of the mounting hole close to the bezel, and the first limiting step abuts against the second limiting step to limit the relative position of the inner liner and the mounting hole.

[0018] Compared with the related art, the beneficial effects of the present invention are:

[0019] The modular watch provided by the present application cleverly decomposes its overall structure into multiple independent modules such as the shell, liner, and bezel. These modules are installed in coordination through locking members and related locking structures to ensure the stability and reliability of the watch during the disassembly and reorganization process. Users can easily replace the shell according to their own aesthetic requirements, such as color preferences, material selection, etc., to show their unique personal style.

[0033] Combination Figure 1 , Figure 2 As shown, this embodiment provides a modular watch, including a housing 100 , an inner shell 200 , a bezel 300 , and a locking member 400 .

[0034] The shell 100 is provided with a mounting hole 110; the inner liner 200 is installed in the shell 100; the bezel 300 is arranged in the mounting hole 110; the locking member 400 is arranged between the shell 100 and the inner liner 200, and the locking member 400 is used to limit the relative position of the inner liner 200 and the shell 100; when the bezel 300 is installed on the shell 100, the locking member 400 can be driven to lock the relative position of the inner liner 200 and the bezel 300 on the shell 100.

[0035] The modular watch provided in this embodiment cleverly decomposes its overall structure into multiple independent modules such as the housing 100, the liner 200, and the bezel 300. These modules are installed in coordination through the locking member 400 and the related locking structure, ensuring the stability and reliability of the watch during the disassembly and reassembly process. The user can easily replace the housing 100 according to his own aesthetic requirements, such as preference for color, choice of material, etc., to show his unique personal style. At the same time, in the face of personalized needs in different occasions, the user can also easily replace the bezel 300 and other modules, so that the appearance of the watch fits the atmosphere of the occasion, whether it is a formal business occasion or a casual party, you can find the most suitable match. This modular design not only greatly improves the practicality of the watch, allowing users to flexibly adjust the configuration of the watch according to different needs, but also adds to the fun of the watch, allowing users to enjoy the fun of doing it themselves in the process of replacing modules.

[0036] like Figure 3As shown, in some specific embodiments, the locking member 400 is an elastic member, and a tightening portion 410 is provided on the locking member 400 on a side facing the mounting hole 110, and an extrusion end 310 is provided on the end face of the bezel 300 facing the shell 100; when the bezel 300 is installed on the shell 100, the extrusion end 310 can squeeze the locking member 400 to deform; in this process, after the tightening portion 410 of the locking member 400 is squeezed, it will move toward the inside of the mounting hole 110 until it is tightly pressed against the outer wall of the inner liner 200, thereby achieving a firm connection between the bezel 300, the locking member 400 and the inner liner 200.

[0037] The matching and installation of the bezel 300 and the housing 100 can be realized in a variety of ways. For example, a threaded structure can be designed to form a threaded connection between the bezel 300 and the housing 100; or a buckle or other matching method can be adopted to firmly mount the bezel 300 on the housing 100 through a snap-fit ​​structure.

[0038] In some specific embodiments, the locking members 400 are evenly distributed with respect to the axial circumference of the inner liner 200; such a design not only takes into account the balance of the distribution of the locking members 400, but also fully considers their uniformity in tightening and limiting the inner liner 200. When the bezel 300 is installed on the housing 100, these evenly distributed locking members 400 will be squeezed at the same time, and each will exert its elastic deformation ability to push the tightening part 410 toward the outer wall of the inner liner 200, thereby forming a uniform and stable tightening force on the entire circumference of the inner liner 200.

[0039] Such a design has several significant advantages. First, since the locking members 400 are evenly distributed, they can share the tightening force on the inner liner 200, avoiding local deformation or damage that may be caused by excessive force on a single point. Second, the evenly distributed locking members 400 can ensure that each position of the inner liner 200 in the circumferential direction is subjected to the same tightening force, thereby improving the stability and reliability of the entire watch structure. Finally, this design also makes it easier for users to operate the locking members 400 when performing watch maintenance or replacing parts, thereby improving the usability of the watch.

[0040] In some specific embodiments, the side surface of the inner liner 200 is provided with a concave surface 210 corresponding to the tightening portion 410, and the concave surface 210 is arc-shaped; the shape, size and position of these concave surfaces 210 are calculated and designed to ensure that when the locking piece 400 is squeezed and deformed, its tightening portion 410 can accurately fall into the corresponding concave surface 210.

[0041] This design brings several significant advantages. First, when the tightening portion 410 falls into the concave surface 210, the connection between the liner 200 and the shell 100 becomes tighter and more stable, effectively preventing the risk of the liner 200 accidentally detaching from the shell 100 when it is affected by adverse factors such as external impact or vibration. Secondly, the presence of the concave surface 210 also provides a clear positioning and support point for the tightening portion 410, so that the locking member 400 can distribute the force more evenly when squeezed, avoiding deformation or damage that may be caused by excessive force on a single point.

[0042] In addition, this design also takes into account the various complex environments that the watch may encounter during use, such as temperature changes, humidity changes, etc., which may affect the structural stability of the watch. By providing a concave surface 210 on the side surface of the inner liner 200 and cooperating with the tightening portion 410 of the locking member 400, the adaptability and durability of the watch in harsh environments can be effectively improved.

[0043] In some specific embodiments, the end surface of the housing 100 close to the bezel 300 is provided with a docking groove 120 corresponding to the extrusion end 310. The design of the docking groove 120 not only takes into account the shape and size of the extrusion end 310 of the bezel 300, but also ensures that when the bezel 300 is installed on the housing 100, the extrusion end 310 can be accurately embedded in the docking groove 120, thereby achieving the initial positioning and matching between the bezel 300 and the housing 100. The inner wall of the docking groove 120 adjacent to the mounting hole 110 is provided with a top tightening hole 130 connected to the mounting hole 110, the locking member 400 is arranged in the docking groove 120, and the top tightening portion 410 is located in the top tightening hole 130; such a layout not only ensures that the locking member 400 can be deformed and moved along a predetermined path when being squeezed, but also improves the matching accuracy and stability between the locking member 400 and the housing 100 and the liner 200. At the same time, since the tightening hole 130 is connected to the mounting hole 110 , this also provides sufficient space for the tightening portion 410 to press the inner liner 200 , thereby achieving a firm fixation of the inner liner 200 .

[0044] In some specific embodiments, the docking groove 120 is an annular groove, and the axis of the docking groove 120 coincides with the axis of the inner liner 200. Such a layout not only improves the overall aesthetics of the watch, but also enhances the stability and reliability of the fit between the bezel 300 and the housing 100. A limiting groove 140 is provided on the inner side wall of the docking groove 120 away from the inner liner 200, and a locking boss 311 corresponding to the limiting groove 140 is provided on the extrusion end 310. The locking boss 311 is penetrated in the limiting groove 140 to limit the relative position of the bezel 300 and the housing 100.

[0045] In some specific embodiments, there are multiple limiting grooves 140 evenly distributed relative to the axial circumference of the inner shell 200; such a design not only takes into account the symmetry and aesthetics of the watch structure, but also ensures that the tightening portion 410 can have a more uniform and stable stress state when cooperating with the limiting groove 140.

[0046] like Figure 4 As shown, in some specific embodiments, the limiting groove 140 is composed of a vertical groove 141 and a horizontal groove 142, the opening direction of the vertical groove 141 is parallel to the axis of the inner liner 200, the opening direction of the horizontal groove 142 is perpendicular to the axis of the inner liner 200, the vertical groove 141 extends toward the end face of the housing 100 close to the bezel 300 to form an opening, and the end of the vertical groove 141 away from the bezel 300 is connected to the horizontal groove 142; when assembling this embodiment, first, the inner liner 200 is inserted into the mounting hole 110 of the housing 100, and then the extrusion end 310 of the bezel 300 is inserted into the docking groove 120, at which time the locking boss 311 on the extrusion end 310 will first enter the vertical groove 141 of the limiting groove 140. As the bezel 300 gradually approaches the housing 100, the extrusion end 310 will produce an extrusion effect on the locking member 400 in the docking groove 120. After being squeezed, the pressing portion 410 of the locking member 400 will move along the inside of the mounting hole 110 toward the outer wall of the inner liner 200 until it is tightly pressed against the inner liner 200, thereby achieving a gradual tightening effect on the inner liner 200.

[0047] When the locking boss 311 moves to the intersection of the vertical groove 141 and the horizontal groove 142, the assembly process enters a critical step. At this time, it is necessary to drive the bezel 300 and the housing 100 to rotate relative to each other. As the rotation proceeds, the locking boss 311 will smoothly fall into the horizontal groove 142, indicating that the assembly of the watch is almost completed. In this process, the elastic force generated by the deformation of the locking member 400 is fully utilized. It not only ensures that the locking boss 311 can stably press against the inner side wall of the horizontal groove 142, but also further enhances the connection strength and stability between the bezel 300, the liner 200 and the housing 100.

[0048] In some specific embodiments, the transverse groove 142 has a recessed portion 1421 near the inner wall of the bezel 300; this design not only enhances the matching accuracy and stability between the locking boss 311 and the transverse groove 142, but also avoids loosening or damage caused by external forces during the use of the watch.

[0049] Specifically, when the locking boss 311 falls into the transverse groove 142, the elastic force generated by the previous squeezing of the locking member 400 will be released. This elastic force not only ensures that the locking boss 311 can be tightly pressed against the inner wall of the transverse groove 142, but also pushes it further into the recessed portion 1421. The presence of the recessed portion 1421 provides a more stable and reliable support point for the locking boss 311, so that the locking boss 311 can be more firmly maintained in the transverse groove 142 when subjected to external force, thereby avoiding the risk of relative rotation between the bezel 300 and the housing 100.

[0050] Such a design not only improves the adaptability and durability of the watch in complex environments, but also provides users with a more reliable and durable watch product. When the watch is affected by adverse factors such as impact or vibration, the design of the recessed portion 1421 can ensure that the matching relationship between the locking boss 311 and the transverse groove 142 remains unchanged, thereby avoiding the watch from loosening or being damaged due to uneven force; and when it is necessary to disassemble this embodiment, the locking boss 311 can be disengaged from the recessed portion 1421 by slightly pressing the bezel 300, and then the bezel 300 and the housing 100 can be driven to rotate relative to each other, which is convenient to operate.

[0051] In some specific embodiments, the end side wall of the inner liner 200 close to the bezel 300 is provided with a first limiting step 220, and the inner side wall of the mounting hole 110 close to the bezel 300 is provided with a second limiting step 111 corresponding to the first limiting step 220, and the first limiting step 220 abuts against the second limiting step 111 to limit the relative position of the inner liner 200 and the mounting hole 110; this design not only ensures that the relative position between the inner liner 200 and the mounting hole 110 can be kept stable and accurate, but also avoids the misalignment phenomenon that may occur during the installation process. Because once the first limiting step 220 contacts the second limiting step 111, an obvious limiting effect will be formed, so that the inner liner 200 cannot move further into the mounting hole 110.

[0052] This design not only improves the efficiency and accuracy of the watch assembly process, but also ensures the stability and reliability of the watch during use. Because the first limiting step 220 and the second limiting step 111 cooperate to limit, the risk of the inner liner 200 being loose or displaced in the mounting hole 110 is effectively prevented, thereby ensuring the overall performance and life of the watch.
