Description

Technical Field

[0001] The utility model relates to the field of intelligent wearable devices, and in particular to a quick-release fixing belt and a wearable device with simplified structure, simple assembly, cost saving and easy operation. Background Art

[0002] With the rapid development and popularization of smart wearable devices (such as smart watches and smart bracelets), quick-release straps or other quick-release fixed straps have become the main selling point of the products. Smart wearable devices use a detachable connection structure to achieve a detachable connection between the main body and the strap or fixed strap, so that users can freely replace the strap or fixed strap.

[0003] The quick-release structure of common smart wearable devices on the market is generally realized by springs, pins and buckles. For example, a movable pin and a button for driving the pin to move are set at the end of the strap, and the spring is in contact with the pin or the button. When the button is pressed, the pin is driven to retract and squeeze the spring, and the strap and the main body can be disassembled at this time; after releasing the button, under the action of the spring, the pin extends and snaps into the buckle on the main body to achieve connection. The current quick-release structure has many and complex assembly parts, and the assembly efficiency is low during production, especially when many parts are assembled on a smaller strap or fixed strap, the assembly is not easy, resulting in reduced efficiency and increased costs. Moreover, for products with smaller buttons, the user is not convenient and fast enough when disassembling the strap or fixed strap, thereby reducing the user experience.

[0004] Therefore, it is necessary to provide a quick-release fixing belt and a wearable device with a simplified structure, simple assembly, cost saving and easy disassembly and assembly operation to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a quick-release fixing belt with simplified structure, simple assembly and cost saving.

[0006] Another object of the present invention is to provide a wearable device with a simplified structure, simple assembly, cost savings, and easy disassembly and assembly operations.

[0007] To achieve the above-mentioned purpose, the technical solution of the utility model is: to provide a quick-release fixing belt, which includes a fixing belt body, a mounting block and a clamping piece; wherein, a receiving groove is opened at the end of the fixing belt body; the clamping piece is of elastic structure and a clamping pin is protruding at one end, the clamping piece can be deformed along the protruding direction of the clamping pin, the clamping piece can be detachably clamped in the mounting block, the clamping pin has a first position protruding outside the mounting block and a second position retracted into the mounting block; the mounting block can be detachably installed in the receiving groove, and when the mounting block is installed in the receiving groove, the clamping pin is located outside the fixing belt body.

[0008] Preferably, a part of the engaging member protrudes or is exposed outside the mounting block to form an extrusion portion, and when the extrusion portion is subjected to force, the engaging member can be elastically deformed and drive the engaging pin to move, and the elastic force of the engaging member can drive the engaging pin to reset. In the present application, the engaging pin and the reset member are integrated into one engaging member, which reduces the number of parts and simplifies the structure. Moreover, during assembly, only the engaging member needs to be assembled, which makes assembly faster, improves production efficiency, and reduces production costs.

[0009] Preferably, the engaging member includes at least one elastic arm, one end of which is bent to form the card pin, and the elastic arm is provided with the extrusion part in the same protruding direction as the card pin, and the extrusion part can elastically deform along the protruding direction of the card pin when a force is applied to the extrusion part. The engaging member is obtained by integrally forming the card pin, the extrusion part, and the elastic arm. Compared with the quick-release structure assembled by the spring, the card pin, and the button in the prior art, the structure of the present application reduces the number of parts and simplifies the structure. Moreover, only the engaging member needs to be assembled during assembly, which is convenient and quick to assemble, improves assembly efficiency, and reduces production costs.

[0010] Preferably, the engaging member includes two elastic arms and a connecting portion, and the ends of the two elastic arms away from the locking pins are respectively connected to the connecting portion, and the two locking pins protrude in opposite directions. Thus, one engaging member can be used to achieve locking at two relative positions, making the locking more stable, and the number of parts and the structure are simplified. Only one step is required for assembly, which is faster and improves production efficiency and reduces production costs.

[0011] Preferably, a mounting groove is provided on the mounting block, the engaging member is detachably engaged in the mounting groove, and the card pin protrudes from at least one side wall of the mounting block in an initial state. When the engaging member is subjected to force, the card pin can move in the mounting groove, thereby engaging with or separating the card pin from the wearable device.

[0012] Preferably, the mounting groove is recessed on the outer side wall of the mounting block or is opened inside the mounting block, and when the engaging member is installed in the mounting groove located inside the mounting block, the engaging pin can be movably penetrated on the side wall of the mounting block.

[0013] Preferably, a notch is recessed on the side wall of the mounting block, and a portion of the engaging member is located in the notch to form an extrusion portion, thereby making the extrusion portion exposed from the mounting block but not protruding from the side wall of the mounting block, so that when the mounting block is installed in the accommodating groove, the extrusion portion will not interfere with the fixing belt body, making the installation of the mounting block easier and quicker; and after installation, directly pressing the fixing belt body can act on the extrusion portion to deform the engaging member, thereby achieving the engagement or separation of the card pin and the wearable device, making the operation of replacing the quick-release fixing belt simpler and more convenient.

[0014] Preferably, when the mounting block is installed in the accommodating groove, all parts of the engaging member except the card pin are accommodated in the accommodating groove, so that the engaging member is fully covered by the fixing belt body to achieve the effect of hiding the engaging member, making the appearance of the quick-release fixing belt simple and beautiful; moreover, squeezing the fixing belt body can apply force to the engaging member to deform it, thereby driving the card pin to move. Compared with the method of setting a special button or driving structure in the prior art, the number of parts in the present application is significantly reduced, and the disassembly and assembly operation is significantly more convenient, thereby improving the user experience.

[0015] Preferably, the mounting block is tightly fitted with the fixing belt body to prevent the mounting block from falling off the fixing belt body during use.

[0016] Correspondingly, the utility model also provides a wearable device, which includes a device body and the quick-release fixing strap as described above; wherein, the device body includes a middle frame, the end of the middle frame is provided with a watch ear slot, and the side wall of the watch ear slot is provided with a watch ear hole; the mounting block is detachably inserted into the watch ear slot, and the card pin is driven to move back and forth through the deformation of the engaging piece to engage in the watch ear hole or detach from the watch ear hole, thereby realizing the installation or removal of the fixing strap body.

[0017] Preferably, the side wall of the lug groove is further provided with a guide groove communicating with the lug hole, and the guide groove extends along the plugging direction of the mounting block.

[0018] Compared with the prior art, the quick-release fixing belt of the utility model only has a mounting block and a clamping piece to form a quick-release structure, and the clamping piece is an elastic structure and has a clamping pin protruding at one end, so the clamping piece can be deformed along the protruding direction of the clamping pin, and the clamping pin and the clamping piece are partially protruding or exposed outside the mounting block. Firstly, the quick-release structure has only two parts, the mounting block and the clamping piece, and the number of parts is small, which simplifies the structure; secondly, during assembly, it is only necessary to clamp the clamping piece to the mounting block and then install the mounting block into the fixing belt body to complete the assembly, with fewer assembly steps and simple operation, thereby improving assembly efficiency and reducing production costs.

[0019] Correspondingly, the wearable device with the quick-release fixing belt also has the above technical effects. Moreover, when assembling the quick-release fixing belt with the device body, it is only necessary to squeeze the fixing belt body to deform the engaging part and drive the card pin to move back and forth, so that the card pin is engaged in the ear hole on the device body or detaches from the ear hole, and the fixing belt body is installed or removed, thereby making it easier for users to replace the fixing belt, improving the user experience and expanding the use scenarios of electronic products.

[0034] The embodiments of the present invention are now described with reference to the accompanying drawings, in which similar element numbers represent similar elements. It should be noted that the orientation descriptions involved in the present invention, such as the orientations or positional relationships indicated by up, down, left, right, front, and back, are all based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the technical solutions of the present application or / and simplifying the description, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limitations on the present application. The first, second, etc. described are only used to distinguish technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0035] Combine first Figure 1-Figure 14 As shown, the quick-release fixing belt 100 provided by the present invention is particularly suitable for wearable device 1, but is not limited thereto. The wearable device 1 can be a smart watch, a smart bracelet, or other electronic products with a detachable fixing belt. The present invention does not specifically limit the wearable device 1.

[0036] Let's combine Figure 1-Figure 10 As shown in the utility model, the quick-release fixing belt 100 includes a fixing belt body 110, a mounting block 120 and a clamping member 130. The end of the fixing belt body 110 is provided with a receiving groove 111. Figure 3 As shown. The mounting block 120 is detachably mounted in the receiving groove 111. The engaging member 130 is an elastic structure and has a protruding card pin 131 at one end. The engaging member 130 can be deformed along the protruding direction of the card pin 131. The engaging member 130 is detachably mounted on the mounting block 120, and the card pin 131 has a first position protruding outside the mounting block 120 and a second position retracted into the mounting block 120. The deformation of the engaging member 130 allows the card pin 131 to move between the first position and the second position, as shown. Figure 7-8As shown. When the mounting block 120 is installed in the receiving groove 111, the locking pin 131 is located outside the fixing belt body 110. Therefore, the quick-release fixing belt 100 is detachably connected to the device body 200 (described later) by the locking pin 131. Moreover, the entire quick-release structure is actually only provided with the mounting block 120 and the locking member 130, and the number of parts is significantly reduced, so that the quick-release structure is simplified, the assembly is convenient, and the assembly efficiency is high, thereby improving production efficiency and reducing production costs.

[0037] Combination Figure 1-Figure 3 As shown, in the present invention, the fixing belt body 110 can be deformed when subjected to external force. For example, the fixing belt body 110 can be an elastic structure or a flexible structure, etc., which is not specifically limited in the present invention. For example, the fixing belt body 110 can be formed using silicone or other materials to make the fixing belt body 110 elastic, or it can be formed by weaving or other forms to make the fixing belt body 110 flexible. In addition, a receiving groove 111 is formed at at least one end of the fixing belt body 110. In this way, on the one hand, after the mounting block 120 is installed in the receiving groove 111, it can be tightly matched with the fixing belt body 110 to prevent the mounting block 120 from falling off from the fixing belt body 110 during use. On the other hand, all parts of the engaging member 130 except the pin 131 are accommodated in the accommodating groove 111, so that the engaging member 130 is fully covered by the fixing belt body 110 to achieve the effect of hiding the engaging member 130, making the appearance of the quick-release fixing belt 100 simple and beautiful. On the other hand, directly squeezing the fixing belt body 110 can apply force to the protruding or exposed part of the engaging member 130 outside the mounting block 120, so that the engaging member 130 is deformed and drives the pin 131 to move between the first position and the second position. Compared with the method of setting a special button or driving structure to drive the pin in the prior art, the present application reduces the number of parts, simplifies the assembly steps of the quick-release fixing belt 100, makes the assembly more convenient, and makes the disassembly and assembly operation between the quick-release fixing belt 100 and the device body 200 more convenient, thereby improving the user experience.

[0038] Combine the following Figure 2 , Figure 5-8 As shown, in the present invention, a part of the engaging member 130 protrudes or is exposed outside the mounting block 120 to form a pressing portion 132, and the pressing portion 132 is spaced apart from the mounting block 120. Therefore, when the pressing portion 132 is subjected to force, the engaging member 130 can be elastically deformed to drive the card pin 131 to move, thereby causing the card pin 131 to retract from the first position protruding from the mounting block 120 into the mounting block 120, that is, causing the card pin 131 to move from the first position to the second position, as shown in FIG. Figure 8The elastic force generated by the engaging member 130 can drive the locking pin 131 to reset, that is, when the squeezing portion 132 loses its force, the elastic force of the engaging member 130 to restore its deformation drives the locking pin 131 to move and reset so that it protrudes out of the mounting block 120 again, as shown in FIG. Figure 5-7 shown.

[0039] See also Figure 2 As shown, in one embodiment of the present invention, the engaging member 130 includes at least one elastic arm 133, the elastic arm 133 is an elastic structure, and one end of the elastic arm 133 is bent to form the card pin 131. The elastic arm 133 is provided with a pressing portion 132 protruding in the same protruding direction as the card pin 131. Specifically, the middle part of the elastic arm 133 protrudes outward to form the pressing portion 132. Therefore, when the pressing portion 132 is subjected to force, the elastic arm 133 can be elastically deformed along the protruding direction of the card pin 131, thereby driving the card pin 131 to reciprocate between the first position and the second position. Of course, the pressing portion 132 is not limited to a protruding structure. Even if the elastic arm 133 is directly set as a straight structure, elastic deformation can also be generated when the elastic arm 133 is subjected to force. In this embodiment, the engaging member 130 is formed by an integrally formed card pin 131, a pressing part 132, and an elastic arm 133. The one engaging member 130 realizes both the engaging and resetting functions. Compared with the quick-release structure assembled by springs, card pins, buttons, etc. in the prior art, the quick-release structure of the present application significantly reduces the number of parts and simplifies the structure. Moreover, only one engaging member 130 needs to be assembled during assembly, which is convenient and quick to assemble, improves assembly efficiency, and reduces production costs. Moreover, directly pressing the fixing belt body 110 can apply force to the pressing part 132, so that the engaging member 130 is deformed to achieve the engagement or separation of the card pin 131 and the wearable device 1, making the operation of replacing the quick-release fixing belt 100 simpler and quicker.

[0040] Recombination Figure 2 , Figure 5-8 As shown, in a specific embodiment, the engaging member 130 includes two elastic arms 133, and the two elastic arms 133 are symmetrically mounted on both sides of the mounting block 120, so that the card pins 131 at the ends of the two elastic arms 133 protrude in opposite directions and protrude from the mounting block 120, and the extrusion parts 132 of the two elastic arms 133 also protrude in opposite directions and protrude or expose the mounting block 120. When the fixed belt body 110 is connected to the device body 200, the two symmetrical card pins 131 are simultaneously engaged with the device body 200, so that the connection is more stable. Moreover, directly squeezing the opposite sides of the fixed belt body 110 can simultaneously press the extrusion parts 132 of the two elastic arms 133, so that the two elastic arms 133 are deformed, thereby causing the two card pins 131 to retract inwards synchronously and detach from the device body 200, and the disassembly operation is more convenient.

[0041] Combine the following Figure 1-2 , Figure 4-8 As shown, in a preferred embodiment of the present invention, the engaging member 130 further includes a connecting portion 134, and one end of the two elastic arms 133 away from the engaging pin 131 is respectively connected to the connecting portion 134, as shown in FIG. Figure 2 As shown. Specifically, the two elastic arms 133 are symmetrically connected to the two ends of the connecting portion 134, and the two clamping pins 131 protrude in opposite directions, thereby connecting the two elastic arms 133 into a whole, that is, the connecting portion 134 and the two elastic arms 133 together constitute the clamping member 130. During molding, a steel wire can be bent to obtain an integrated clamping member 130, of course, it is not limited to this. Therefore, the clamping member 130 can be used to achieve the clamping with the device body 200 at two relative positions, making the clamping more stable; and the number of parts for clamping and resetting is significantly reduced, reducing the number of parts of the quick-release structure and simplifying the structure; in addition, during assembly, only one step is required to assemble the clamping member 130 to the mounting block 120, simplifying the assembly steps, making the assembly faster, improving production efficiency, and reducing production costs.

[0042] Combine the following Figure 2 , Figure 4 As shown, in the present invention, the mounting block 120 is provided with a mounting groove 121, and the engaging member 130 is detachably engaged in the mounting groove 121, and the engaging pin 131 and the pressing portion 132 are protruded from at least one side wall of the mounting block 120. In this way, when the pressing portion 132 is subjected to force, the elastic arm 133 can move in the mounting groove 121, thereby driving the engaging pin 131 to move back and forth, thereby achieving engagement or separation with the device body 200.

[0043] Combine the following Figure 4-Figure 8 As shown, in a specific embodiment of the present invention, the mounting block 120 is an integrally formed block structure, and the mounting groove 121 is provided on the outer wall of the mounting block 120. Specifically, the mounting groove 121 is provided on the opposite side walls and the rear end wall of the mounting block 120, and the mounting groove 121 has a certain width at least in the front groove section 121a close to the front end wall of the mounting block 120, see Figure 4 , Figure 6 In this specific embodiment, the installation groove 121 formed on the two side walls of the installation block 120 has a certain width, which is used for the elastic arm 133 to move in the installation groove 121 on the two side walls of the installation block 120. Figure 2 , Figure 6As shown, when the engaging member 130 is assembled on the mounting block 120, the engaging member 130 is pushed from the rear end of the mounting block 120 so that the two elastic arms 133 are respectively inserted into the mounting grooves 121 on the two side walls, and the connecting portion 134 is inserted into the mounting groove 121 on the rear end wall. The assembled state is as shown in FIG. Figure 5-6 After the assembly is completed, the two locking pins 131 are respectively in contact with the front slot section 121a at the front end of the installation slot 121, and in the initial state, the two locking pins 131 are both protruding from the installation block 120 and are in the first position, as shown in FIG. Figure 5-7 When the two elastic arms 133 are subjected to force, the two locking pins 131 can be driven to move toward each other in the front slot section 121a and retract into the installation slot 121, so that the locking pins 131 are in the second position, as shown in FIG. Figure 8 The arrangement of the mounting groove 121 enables the mounting block 120 to be obtained by one-time molding, and the molding method is simpler and the manufacturing cost is lower.

[0044] Continue to combine Figure 4-8 As shown, in this specific embodiment, the two side walls of the mounting block 120 are concavely provided with notches 122, and the two notches 122 are concave toward the middle of the mounting block 120 and are symmetrical, and the notches 122 are used to accommodate the extrusion portion 132, so that the extrusion portion 132 is exposed outside the mounting block 120 and is spaced apart from the mounting block 120, as shown in FIG. Figure 5-8 As shown, there is space for the elastic arm 133 to move. Moreover, the setting of the notch 122 makes the protruding extrusion part 132 exposed but not protruding from the side wall of the mounting block 120, so that when the mounting block 120 is installed in the receiving groove 111, the extrusion part 132 will not interfere with the fixed belt body 110, making the installation of the mounting block 120 easier and faster. After installation, the extrusion part 132 is also wrapped in the fixed belt body 110, achieving the effect of hiding the engaging part 130, and there are no exposed parts outside the fixed belt body 110, and the appearance is simple and beautiful; at the same time, directly pressing the fixed belt body 110 can act on the extrusion part 132 to deform the elastic arm 133, so as to achieve the engagement or separation of the card pin 131 and the device body 200, making the operation of replacing the quick-release fixing belt 100 simpler and more convenient.

[0045] It is understandable that, in the method where the protruding extrusion portion 132 is not provided on the elastic arm 133, the elastic arm 133 itself is directly inserted into the notch 122, so that the portion of the elastic arm 133 exposed from the mounting block 120 is spaced apart from the mounting block 120, and the portion of the elastic arm 133 located in the notch 122 also forms the extrusion portion 132.

[0046] Combine the following Figure 9-10As shown, in another specific embodiment of the utility model, the setting mode of the mounting groove 121 is different from the above-mentioned embodiment. Specifically, the mounting groove 121 is opened inside the mounting block 120. That is, the mounting groove 121 is formed by directly recessing the top surface of the mounting block 120, and the length of the mounting groove 121 corresponds to the length of the elastic arm 133. In this way, when the elastic arm 133 is installed in the mounting groove 121, the two ends of the elastic arm 133 can abut against the front and rear walls of the mounting groove 121 to achieve a stable connection. Furthermore, the width of the mounting groove 121 also corresponds to the spacing between the two elastic arms 133. Therefore, when the engaging member 130 is directly pressed into the mounting groove 121 from the top, the two elastic arms 133 directly abut against the two side walls of the mounting block 120, and the connecting portion 134 abuts against the rear side wall of the mounting block 120, so that the engaging member 130 is more stably accommodated in the mounting groove 121.

[0047] In this specific embodiment, through holes are provided on the two side walls of the mounting block 120 for the card pin 131 to pass through. When the engaging member 130 is installed, the card pin 131 passes through the through holes on the two side walls of the mounting block 120 and protrudes out of the two side walls. Fig. 9 shown.

[0048] In this specific embodiment, the two side walls of the mounting block 120 are also provided with notches 122 for accommodating the extrusion portion 133, and the notches 122 are connected to the internal mounting groove 121. The molding method and function of the notches 122 are the same as those in the above embodiment, and will not be described again.

[0049] Continue to combine Figure 9-10 As shown, in this specific embodiment, the mounting block 120 is further provided with a cover 123, and the shape and outer diameter of the cover 123 correspond to those of the mounting groove 121. When the engaging member 130 is pressed into the mounting groove 121, the cover 123 is further pressed into the mounting groove 121 and covers the top of the mounting block 120, so that the mounting block 120 and the cover 123 cooperate to obtain a block-shaped structure, which facilitates the mounting block 120 to be installed in the receiving groove 111 of the fixing belt body 110.

[0050] Combine the following Figure 11-Figure 14 As shown, the present invention further provides a wearable device 1, which includes a device body 200 and the quick-release fixing belt 100 as described above. The structure of the quick-release fixing belt 100 is as described above and will not be described again. The device body 200 can be, for example, a dial of a smart watch or a functional end of a bracelet, and the quick-release fixing belt 100 can be a watch strap, etc., and neither is specifically limited in the present invention.

[0051] Combination Figure 12-14As shown, in the present invention, the device body 200 includes a middle frame 210, at least one end of the middle frame 210 is provided with a lug slot 211, and the side wall of the lug slot 211 is provided with a lug hole 212. The quick release fixing belt 100 is detachably installed in the lug slot 211. In a specific embodiment, both ends of the middle frame 210 are provided with a lug slot 211, such as Fig.13 As shown, it is used to be detachably connected to both ends of the quick-release fixing belt 100, so that the device body 200 and the quick-release fixing belt 100 form a ring. Of course, it is not limited to this arrangement. The mounting block 120 of the quick-release fixing belt 100 is detachably inserted into the lug groove 211, and the deformation of the elastic arm 133 drives the clamping pin 131 to move back and forth and engage in or disengage from the lug hole 212 to achieve the installation or removal of the fixing belt body 110.

[0052] Continue to view Fig.13 As shown, in a preferred embodiment, the side wall of the lug slot 211 is further provided with a guide slot 213 connected to the lug hole 212, and the guide slot 213 extends along the plugging direction of the mounting block 120, and the guide slot 213 has a guiding and certain positioning function. In this way, when the card pin 131 is not completely retracted into the mounting block 120, the card pin 131 can slide along the guide slot 213, so as to be accurately inserted into the lug hole 212 or detached from the middle frame 210.

[0053] Continue to view Fig.12 As shown, the device body 200 further includes a screen assembly 220 and a back cover 230. The screen assembly 220 and the back cover 230 are respectively assembled on the upper and lower sides of the middle frame 210. The assembly method of the two and the middle frame 210 is a conventional method in the art and will not be described in detail. It can be understood that in other embodiments, the device body 200 can be set to other structural forms.

[0054] Combine again below Figure 1-Figure 14 As shown, Figure 1-8 Taking the quick-release fixing belt 100 shown in the figure as an example, when assembling the wearable device 1, only three steps are needed to complete the assembly of the quick-release fixing belt 100 and the device body 200. The details are as follows:

[0055] First, the engaging member 130 is installed into the mounting block 120. That is, the engaging member 130 is pushed from the rear end of the mounting block 120 so that the two elastic arms 133 move along the two side walls of the mounting block 120, and finally the two elastic arms 133 are respectively inserted into the mounting grooves 121 on the two side walls, and the connecting portion 134 is inserted into the mounting groove 121 on the rear end wall. Figure 5-6As shown, the locking member 130 is stably installed. At this time, the two locking pins 131 are located in the front groove section 121a at the front end of the mounting block 120, and in the initial state, the two locking pins 131 protrude from the two side walls of the mounting block 120. The two extrusion parts 132 are located in the notches 122 on the two side walls of the mounting block 120.

[0056] Secondly, the installation block 120 is pressed into the receiving groove 111 on the fixed belt body 110 so that the two pins 131 at the front end are located outside the fixed belt body 110. Of course, the installation block 120 can also be completely pressed into the receiving groove 111, and the pins 131 pass through the fixed belt body 110 and protrude out of the fixed belt body 110. During the pressing process, since the extrusion portion 132 of the engaging member 130 does not protrude from the side wall of the installation block 120, it will not interfere with the movement of the installation block 120, making it easier to press the installation block 120 into the elastic fixed belt body 110, shortening the assembly time and improving the assembly efficiency. After the installation is completed, the installation block 120 is tightly matched with the fixed belt body 110 to prevent the installation block 120 from falling off from the fixed belt body 110 during use. Furthermore, the pressing part 132 of the engaging member 130 is also wrapped in the fixing belt body 110, so that the engaging member 130 is hidden, and there is no exposed part outside the fixing belt body 110, and the appearance is simple and beautiful. At the same time, the pressing part 132 can be exerted by directly pressing the two sides of the fixing belt body 110.

[0057] Finally, the quick-release fixing belt 100 is installed in the ear slot 211 on the device body 200. Specifically, pressing the two sides of the fixing belt body 110 can apply force to the extrusion part 132 to deform the elastic arm 133, thereby driving the two card pins 131 to move inward and retract into the installation block 120. Figure 8 As shown. Then, the mounting block 120 is inserted into the lug slot 211 on the middle frame 210. After the fixing belt body 110 is released, the elastic arm 133 is reset under the action of the elastic force and drives the two card pins 131 to move out, thereby being inserted into the lug holes 212 for clamping. In one embodiment, the two ends of the quick-release fixing belt 100 are respectively installed in the lug slots 211 at the two ends of the device body 200, so that the quick-release fixing belt 100 and the device body 200 form a ring. After the installation is completed, the end of the fixing belt body 110 abuts against the end of the device body 200, and there are no exposed parts on the fixing belt body 110, such as Fig.14 As shown, the appearance of the entire wearable device 1 is simple and beautiful.

[0058] When the quick-release fixing belt 100 needs to be removed, the two sides of the fixing belt body 110 are pressed to apply force to the pressing portion 132, so that the elastic arm 133 is deformed, thereby driving the two locking pins 131 to move inward and retract into the mounting block 120. Figure 8At this time, the pin 131 is separated from the lug hole 212, and the fixing belt body 110 can be pulled out of the lug groove 211, so that the quick-release fixing belt 100 can be removed.

[0059] In summary, the quick-release fixing belt 100 of the utility model is only provided with a detachably connected mounting block 120 and a snap-fitting member 130 to form a quick-release structure, and the snap-fitting member 130 is an elastic structure and has a snap-fitting pin 131 protruding at one end, and the snap-fitting member 130 can be deformed along the protruding direction of the snap-fitting pin 131, and the snap-fitting pin 131 and the snap-fitting member 130 partially protrude or are exposed outside the mounting block 120. Firstly, the quick-release structure has only two parts, the mounting block 120 and the snap-fitting member 130, and the number of parts is small, so that the structure is simplified; secondly, during assembly, it is only necessary to snap the snap-fitting member 130 into the mounting block 120, and then install the mounting block 120 into the fixing belt body 110 to complete the assembly, and the assembly steps are few and the operation is simple, thereby improving the assembly efficiency and reducing the production cost.

[0060] Correspondingly, the wearable device 1 having the quick-release fixing belt 100 also has the above technical effects. Moreover, when assembling the quick-release fixing belt 100 with the device body 200, it is only necessary to squeeze the fixing belt body 110 to deform the engaging member 130 and drive the card pin 131 to move back and forth, so that the card pin 131 is engaged in the ear hole 212 on the device body 200 or is separated from the ear hole 212, so as to realize the installation or removal of the fixing belt body 110, thereby making it easier for users to replace the fixing belt, improving the user experience, and expanding the use scenarios of electronic products.

[0061] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
