Description

Technical Field

[0001] This utility model relates to the technical field of wearable devices, and in particular to a quick-release magnetic buckle and a wearable device. Background Technology

[0002] Traditional clasp mechanisms, a common fastening structure in watch straps, are widely used due to their comfort, fit, and aesthetics. However, long-term use and practical experience reveal several typical drawbacks: First, traditional clasps require the use of both hands (thumbs pressing the unlocking points on both sides and index fingers pushing the clasp surface). The unlocking force must be controlled; too little force may prevent the clasp from opening, while too much force can cause discomfort to the fingers. If the spring tension decreases, it can lead to "one-sided opening and one-sided jamming," which is particularly unfriendly to the elderly, children, or users with poor hand dexterity. Second, the internal springs and micro-shafts of traditional clasps are subjected to constant stress, which can lead to problems such as decreased spring tension causing loosening, worn shafts causing abnormal noises during opening and closing, and deformed meshing teeth causing locking failures. Third, traditional clasps have numerous parts, a complex structure, and high manufacturing costs. Utility Model Content

[0028] Please refer to Figures 1-5This utility model provides a quick-release magnetic buckle 100, which includes a first fastening assembly 110 and a second fastening assembly 120. The first fastening assembly 110 includes a first fastening member 111 and a first magnetic member 112. The first fastening member 111 includes a fixing groove 1111 for mounting the first magnetic member 112. The second fastening assembly 120 includes a second fastening member 121 and a second magnetic member 122. The second fastening member 121 is rotatably connected to the first fastening member 111. The second fastening member 121 includes a fixing structure 1211 for fixing the second magnetic member 122. The first magnetic member 112 cooperates with the second magnetic member 122. The first fastening member 111 and the second fastening member 121 are integrally formed by sheet metal stamping and bending. For example, in this embodiment, both the first magnetic component 112 and the second magnetic component 122 are neodymium iron boron permanent magnets. However, in specific applications, one of the first magnetic component 112 and the second magnetic component 122 may be a neodymium iron boron permanent magnet, while the other may be a component that can be attracted by a magnet. The fixing groove 1111 is a rectangular groove, and the first magnetic component 112 is a square block. When installing the first magnetic component 112, glue is first applied to the surface of the fixing groove 1111, and then the first magnetic component 112 is bonded into the fixing groove 1111. Specifically, the first fastening component 111 and the second fastening component 121 are generally arc-shaped sheet structures. In particular, the first fastening component 111, the second fastening component 121, the fixing groove 1111, and the fixing structure 1211 are all processed from sheet metal through stamping and bending processes.

[0029] The quick-release magnetic buckle 100 and wearable device in this embodiment enable the quick fastening and disengagement of the wearable device by means of the cooperation between the first magnetic element 112 and the second magnetic element 122. In addition, since the first fastening element 111, the second fastening element 121, the fixing groove 1111 and the fixing structure 1211 are all obtained by stamping and bending processes, it is beneficial to simplify the manufacturing process, reduce manufacturing costs and reduce the number of parts.

[0030] The core innovation of this application lies in the extremely reduced production cost, the extremely reduced number of parts, and the extremely simplified process. The buckle in this embodiment uses sheet metal material and stamping and bending processes to reduce the difficulty of manufacturing.

[0031] Please refer to Figure 4 and Figure 5In one possible implementation, the fixing structure 1211 includes a first fixing feature 1211A and a second fixing feature 1211B, which are respectively disposed on adjacent sides of the second magnetic element 122. Exemplarily, two of each of the first fixing features 1211A and the second fixing feature 1211B are provided, with the two first fixing features 1211A and the two second fixing features 1211B arranged opposite each other. That is, the first fixing features 1211A, the second fixing features 1211B, the first fixing features 1211A, and the second fixing features 1211B are arranged sequentially. The first fixing features 1211A and the second fixing features 1211B are configured as sheet metal features obtained by bending. The first fixing features 1211A and the second fixing features 1211B are used to limit the movement of the second magnetic element 122.

[0032] Please refer to Figure 4 and Figure 5 In one possible implementation, the second fixing feature 1211B includes a limiting portion 1201 and a bending portion 1202, which are connected. The second magnetic element 122 includes a fastening groove 1221, and the bending portion 1202 is embedded in the fastening groove 1221. Exemplarily, the bending portion 1202 is fully embedded in the fastening groove 1221, further fastening and fixing the second magnetic element 122.

[0033] Please refer to Figure 4 and Figure 5 In one possible implementation, the fixing structure 1211 includes a first clearance groove 1211C and a second clearance groove 1211D. A first fixing feature 1211A is disposed in the first clearance groove 1211C, and a second fixing feature 1211B is disposed in the second clearance groove 1211D. Exemplarily, the position and number of the first clearance grooves 1211C correspond to the first fixing feature 1211A, and the position and number of the second clearance grooves 1211D correspond to the second fixing feature 1211B.

[0034] Please refer to Figure 2 and Figure 3 In one possible implementation, the first fastening member 111 has a first reinforcing rib 1112, and the second fastening member 121 has a second reinforcing rib 1212. Exemplarily, two first reinforcing ribs 1112 and two second reinforcing ribs 1212 are provided. The first and second reinforcing ribs 1112 and 1212, through partial protrusions, increase the structural strength of the sheet metal part without increasing the overall thickness of the fastening member.

[0035] Please refer to Figure 1 and Figure 4In one possible implementation, the second fastening assembly 120 further includes a rivet 123, which is fixed to the second fastening member 121 by riveting. The rivet 123 is located between the second reinforcing rib 1212 and the fixing structure 1211. Exemplarily, the rivet 123 cooperates with the watch strap to allow the wearable device to be worn on the user's wrist. Firstly, this enhances the connection stability of the rivet 123. Riveting is a reliable connection method, and the rivet 123 is fixed to the second fastening member 121 by riveting, ensuring a tight connection between the two. During daily use of the wearable device, regardless of external forces such as tension, torsion, or vibration, the connection between the rivet 123 and the second fastening member 121 remains stable and will not easily loosen or fall off. For example, when people exercise, their wrists swing frequently, and the buckle is subjected to forces in various directions. The riveted fastener 123 ensures the structural integrity of the second fastening component 121, thereby maintaining the normal function of the entire buckle and preventing the buckle from being affected by loosening of the fastener 123, thus ensuring that the wearable device is stably worn by the user. Secondly, the operation is simple and easy to assemble. The riveting process is relatively simple. During the production process, pressure is applied to the fastener 123 using special tools to fix it to the second fastening component 121, which is convenient and efficient. This helps to improve the production efficiency of the quick-release magnetic buckle 100 and reduce production difficulty and cost. At the same time, this simple and reliable assembly method makes it easy for workers to quickly master the operating skills, reduces product quality problems caused by complex assembly processes, improves product consistency and yield, and makes large-scale production easier to achieve.

[0036] Please refer to Figure 2 In one possible implementation, when fastened, the second magnetic element 122 is at least partially located within the fixing groove 1111. Exemplarily, the first magnetic element 112 is entirely located within the fixing groove 1111, and there is a certain distance between the first magnetic element 112 and the opening of the fixing groove 1111, leaving space for the second magnetic element 122. When the quick-release magnetic buckle 100 is fastened, the surface of the first magnetic element 112 is in direct contact with the surface of the second magnetic element 122, which helps to enhance the adsorption force. Furthermore, since the second magnetic element 122 is partially located within the fixing groove 1111 at this time, it helps the user protect both the first and second magnetic elements 112 during use.

[0037] Please refer to Figure 1 and Figure 2 In one possible implementation, the quick-release magnetic buckle 100 further includes a cover 130, which is connected to the first fastening member 111. Exemplarily, the cover 130 serves to protect the first magnetic member 112, the second magnetic member 122, the fixing structure 1211, and the fixing groove 1111. Furthermore, the cover 130 also serves an aesthetic purpose.

[0038] Please refer to Figure 3 In one possible implementation, the first fastening member 111 includes a forming groove 1113, which communicates with the fixing groove 1111. Exemplarily, multiple forming grooves 1113 are provided. The fixing groove 1111 in this embodiment is also obtained by stamping. However, since the fixing groove 1111 is relatively deep, it undergoes significant deformation during stamping. Therefore, multiple forming grooves 1113 are provided to accommodate the deformation generated during stamping, preventing the first fastening member 111 and the second fastening member 121 from cracking during stamping.

[0039] The second objective of this utility model is to provide a wearable device (not shown in the figure), which includes the aforementioned quick-release magnetic buckle 100. Exemplarily, the wearable device in this embodiment includes a smartwatch, smart bracelet, smart glasses, smart helmet, smart headphones, etc., and the quick-release magnetic buckle 100 serves to attach the wearable device to the user's body.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
