Description

[Technical Field]

[0001] The present invention relates to the technical field of vibration motors, and more particularly to vibration motors. [Background technology]

[0002] Conventional vibration motors generally have flaws in their structural design, and their mounting parts and assembly steps are complicated. The assembly steps are usually in an incremental relationship, meaning that the next assembly step cannot proceed until the previous assembly step is completed. If an error occurs in any one assembly step, it will affect the progress of the subsequent assembly steps, reducing the overall efficiency.

[0003] In addition, the complicated installation parts and installation steps also lead to a decrease in maintenance efficiency. If a part inside the vibration motor breaks down, maintenance requires the removal of multiple components, and in some cases, even the destructive removal of the broken part is required. This not only consumes a lot of time and effort, but also may cause further damage due to improper operation and damage to other normal parts. Therefore, in most cases, when a vibration motor breaks down, the only option is to replace the entire motor, which not only increases the usage cost but also wastes resources.

[0004] Therefore, how to design a vibration motor that allows easier installation and removal for maintenance is a problem that must be solved by those skilled in the art. Summary of the Invention [Problem to be solved by the invention]

[0020] It should also be understood that the terms used in the specification of the present invention are merely for the purpose of describing particular embodiments and are not intended to limit the present invention. When used in the specification of the present invention and the accompanying utility model claims, the singular forms "a," "one," and "the" are intended to include the plural forms unless the context clearly dictates otherwise.

[0021] Furthermore, the term "and / or" as used in the specification and appended claims should be understood to refer to and include any and all possible combinations of one or more of the associated listed items.

[0022] 1 to 3, the vibration motor according to the embodiment of the present invention specifically includes a housing module 10 and a coil mounting module 20. The housing module 10 is provided with a mounting cavity 11 that opens toward the side, and a magnet group is provided in the mounting cavity 11, and the magnet group includes two magnets 12 that are arranged one above the other, The coil mounting module 20 is removably fitted into the mounting cavity 11 and is provided with a coil 21, which is mounted between two magnets 12 of the magnet group.

[0023] In this embodiment, the vibration motor is divided into a housing module 10 and a coil mounting module 20, and in the production assembly process, the assembly and adjustment of the two modules are carried out separately. After the individual assembly and adjustment of the two modules are completed, the two modules can be assembled into a complete vibration motor, thereby avoiding mutual interference between the assembly steps and improving production efficiency.

[0024] Moreover, in this embodiment, the coil mounting module 20 is designed to be removably inserted and mounted within the housing module 10, ensuring flexibility in removing and mounting the module. If a part inside the vibration motor fails, the coil mounting module 20 can be removed by simply pulling it out of the housing module 10. Then, by simply replacing the relevant module or the specific failed part within the module, the functionality of the vibration motor can be quickly restored, eliminating the need to replace the entire vibration motor. This not only improves the maintenance efficiency of the equipment, but also effectively reduces maintenance costs, extends the service life of the equipment, and ensures the stability and reliability of the overall operation.

[0025] In one embodiment, the coil mounting module 20 includes a mounting portion 22 and a recess portion 23. The mounting portion 22 fits into the opening of the housing module 10 and is fixed to the housing module 10 via a fastening structure; The fitting portion 23 is provided to protrude from the side of the mounting portion 22 facing the mounting cavity 11, and the coil 21 is provided in the fitting portion 23.

[0026] In this embodiment, the mounting portion 22 of the coil mounting module 20 is designed to precisely fit the opening of the housing module 10, and a fastening structure is used to achieve a strong connection between the coil mounting module 20 and the housing module 10, ensuring a simple and quick installation process.

[0027] In addition, in this embodiment, an insertion portion 23 facing the mounting cavity 11 is provided in the mounting portion 22, and the coil 21 is provided in the insertion portion 23, so that the insertion portion 23 can be inserted into the mounting cavity 11 via the mounting portion 22 and attached, and the coil 21 and the magnet group can be accurately aligned.

[0028] In addition, in this embodiment, the layout design of the mounting portion 22, the insertion portion 23 and the mounting cavity 11 effectively improves the space utilization rate of the vibration motor, making the structure of the vibration motor more compact and improving the vibration performance.

[0029] In one embodiment, engaging grooves 221 are provided on both sides of the mounting portion 22, and engaging protrusions 13 are provided at corresponding mounting positions on the housing module 10, and the mounting portion 22 and the housing module 10 are connected by engagement between the engaging grooves 221 and the engaging protrusions 13.

[0030] In this embodiment, a guide function is realized by providing engagement grooves 221 on both sides of the mounting portion 22, and accurate connection and engagement is achieved by the engagement grooves 221 and the engagement protrusions 13 of the housing module 10. During assembly, quick connection can be achieved by simply aligning the engagement grooves 221 of the mounting portion 22 with the engagement protrusions 13 of the housing module 10 and pressing them together. This enables the combined connection or fixed connection of the coil mounting module 20 and the housing module 10, simplifies the assembly flow, and improves assembly efficiency.

[0031] In a specific embodiment, to avoid the problem of the connection between the coil mounting module 20 and the housing module 10 becoming loose due to vibration during use of the vibration motor, the housing module 10 and the coil mounting module 20 (i.e., the mounting portion 22) may be further provided with communicating anti-loosening screw holes, and fastening with screws that pass through the housing module 10 and the coil mounting module 20 further enhances the stability of the connection and prevents loosening due to vibration. When the coil mounting module 20 needs to be replaced, the mounting portion 22 can be removed by simply loosening the anti-loosening screws and a new module can be quickly installed. This not only simplifies the maintenance steps, but also shortens maintenance time and costs, and ensures the long-term operational stability of the equipment.

[0032] In addition, in other embodiments, the connection engagement method between the engagement groove 221 and the engagement protrusion 13 may be set to an interference fit without providing an anti-loosening screw hole. The tight engagement achieved by the interference fit ensures that the connection between the mounting portion 22 and the housing module 10 remains stable even in a vibration environment, and no additional fastening members are required, further simplifying the structure.

[0033] It can be understood that the mounting portion 22 and the housing module 10 may be fastened together using an interference fit, or may be fastened using an anti-loosening screw, or may be fastened by both an interference fit and an anti-loosening screw at the same time, and the specific fastening method can be flexibly selected according to the actual application needs to achieve the optimal connection effect.

[0034] In one specific embodiment, two sets of coils 21 are provided, and the two sets of coils 21 are arranged side by side in the insertion portion 23, and two sets of magnet groups are provided corresponding to the coils 21. By arranging two sets of coils 21 side by side in the insertion portion 23 corresponding to the two sets of magnets 12 respectively, a double coil 21 structure is formed, which enhances the magnetic field effect and increases the vibration strength.

[0035] It can be understood that each set of magnets 12 includes two magnets 12 arranged one above the other, and a coil 21 is arranged between the two magnets 12 arranged one above the other, so that the current magnetic field of the coil 21 interacts with the magnetic field of the magnets 12 to convert electrical energy into mechanical energy, thereby realizing the vibration effect of the vibration motor.

[0036] Of course, in other specific embodiments, the number of coils 21 can be flexibly adjusted according to the needs of the actual application scenario to meet different vibration intensity requirements. For example, in scenarios requiring higher vibration intensity, the number of coils 21 can be increased and the arrangement of the magnet group can be adjusted accordingly to ensure an improved vibration effect.

[0037] In one embodiment, the fitting portion 23 is provided with a mounting hole 231 for mounting the coil 21. The shape of the mounting hole 231 is adapted to the shape of the coil 21, and the fitting portion 23 is provided with the mounting hole 231 recessed inward for mounting the coil 21, thereby further improving the space utilization rate of the vibration motor.

[0038] In one embodiment, the insertion portion 23 is further provided with a mounting iron piece 24 , which is fixed below the mounting hole 231 , and the coil 21 is provided on the mounting iron piece 24 .

[0039] In this embodiment, the coil 21 is supported by the mounting iron piece 24 below the mounting hole 231, so that the coil 21 is secured not to fall off after being fitted into the mounting hole 231 and mounted.

[0040] In specific application scenarios, the mounting iron piece 24 can be selected to be integral with the insertion portion 23 or to be manufactured separately and then inserted according to the requirements of the actual production process.

[0041] In one embodiment, a flexible circuit board 25 is attached to the outer surface of the mounting portion 22, and the flexible circuit board 25 is electrically connected to the coil 21.

[0042] In this embodiment, a flexible circuit board 25 is attached to the outer surface of the mounting portion 22 to control the vibration of the vibration motor. Compared with the rigid circuit boards commonly used in the prior art, the flexible circuit board 25 has better bendability and adaptability, which can effectively reduce circuit damage caused by vibration and extend the service life of the device. In addition, the flexible circuit board 25 can be bent and folded at any position, which increases installation flexibility, simplifies installation and layout, and improves the flexibility and reliability of the entire structure.

[0043] For example, the outer surface of the mounting portion 22 may be provided with an inwardly recessed groove, and the flexible circuit board 25 may be fitted into the groove, which not only makes full use of the mounting space but also ensures a tight connection between the flexible circuit board 25 and the mounting portion 22.

[0044] In one embodiment, the housing module 10 includes a bottom case 14 and a top case 15 that are snap-fit ​​together to form the mounting cavity 11 .

[0045] In this embodiment, the bottom case 14 and the top case 15 are snap-fit ​​together to form the mounting cavity 11, which houses each component of the vibration motor, ensuring a compact and strong structure.

[0046] In specific application scenarios, the fixing method between the bottom case 14 and the top case 15 can be selected according to the actual situation, and various methods such as screw fixing, snap connection or adhesive bonding can be used to adapt to the installation needs in various environments.

[0047] In one embodiment, the housing module 10 further includes a first counterweight member 16 and a second counterweight member 17 mounted within the mounting cavity 11, the first counterweight member 16 and the second counterweight member 17 being mounted on the top case 15 and the bottom case 14, respectively.

[0048] The two upper and lower magnets 12 of the magnet group are provided inside the first counterweight member 16 and the second counterweight member 17, respectively.

[0049] In this embodiment, the cooperation of the first counterweight member 16 and the second counterweight member 17 ensures that the upper and lower magnets 12 of the magnet group are firmly fixed to the top case 15 and the bottom case 14, respectively, thereby effectively preventing the magnets 12 from being displaced during vibration, optimizing the magnetic field distribution and improving the stability and working efficiency of the vibration motor. In addition, the first counterweight member 16 and the second counterweight member 17 can also perform the counterweight function required for the vibration motor, and by rationally adjusting their weight distribution, the dynamic balance and vibration effect of the vibration motor can be further optimized.

[0050] In one embodiment, the first counterweight member 16 and the second counterweight member 17 are fixedly connected via a snap mechanism.

[0051] In this embodiment, the first counterweight member 16 and the second counterweight member 17 are connected and fixed via snap structures on both sides of each counterweight member, ensuring a sturdy and convenient connection and avoiding the cumbersome operation of conventional screw fastening. After the two upper and lower magnets 12 of the magnet group are fixed to the first counterweight member 16 and the second counterweight member 17 respectively, the two are snap-fitted together to form a complete magnet group, and the coil mounting module 20 can be inserted to perform electromagnetic energy conversion.

[0052] In one embodiment, the upper and lower magnets 12 of the magnet group are fixed to the inside of the first counterweight member 16 and the second counterweight member 17 by adhesive bonding, respectively. The back sides of the first counterweight member 16 and the second counterweight member 17 are fixed to the top case 15 and the bottom case 14, respectively, via adhesive.

[0053] In this embodiment, the magnet 12 can be fixed to the counterweight member and the counterweight member can be fixed to the bottom case 14 and the top case 15 by adhesive.

[0054] Specifically, as shown in Figures 4 and 5, when assembling the vibration motor, the upper and lower magnets 12 of the magnet group may first be fixed to the first counterweight member 16 and the second counterweight member 17, respectively. Next, the first counterweight member 16 and the second counterweight member 17 with the magnets 12 attached thereto may be attached to the corresponding positions of the top case 15 and the bottom case 14, respectively, and then the top case 15 and the bottom case 14 may be snap-fitted together to form a complete mounting cavity 11 (see Figure 1) for fitting the coil mounting module 20. This completes the assembly. Of course, it is also possible to first snap-fit ​​the first counterweight member 16 with the magnets 12 attached thereto and the second counterweight member 17, and then attach the top case 15 to the top of the first counterweight member 16 and the bottom case 14 to the bottom of the second counterweight member 17; the specific assembly order can be flexibly adjusted according to actual needs.

[0055] Preferably, in specific application scenarios, the first counterweight member 16 and the second counterweight member 17 may be made of metal, which not only increases the weight of the counterweight members but also allows for magnetic attraction engagement with the magnet 12. Furthermore, combined with adhesive fixation between the magnet 12 and the counterweight members, the position of the magnet 12 can be more appropriately fixed, ensuring that it does not move during operation and always aligns with the coil.

[0056] Each embodiment in the specification is described in a progressive manner, with each embodiment being described with an emphasis on the differences from other embodiments, and the same or similar parts between the embodiments may be referred to. Since the systems disclosed in the embodiments correspond to the methods disclosed in the embodiments, the descriptions thereof are relatively simple, and relevant parts may be referred to in the partial descriptions of the methods. Those skilled in the art may make minor improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications are also within the scope of protection of the utility model claims of the present application.

[0057] It should be further explained that, in this specification, relational terms such as "first," "second," etc., are used only to distinguish one entity or operation from another, and do not necessarily require or imply the existence of any such actual relationship or order between those entities or operations. Furthermore, the terms "comprise," "comprises," or any other variations thereof are intended to cover non-exclusive inclusions, whereby a process, method, article, or device comprising a set of elements not only includes those elements, but also includes other elements not expressly listed or elements inherent in such process, method, article, or device.
