[0002] Most smart wearable electronic devices, such as smartwatches and smart bracelets, have detachable straps. The two straps are normally separate and are connected by a buckle when worn.

[0003] Currently, there are generally two types of buckles for connecting this type of watch strap. One is the traditional pin buckle structure, which uses a pin inserted into a hole to engage. This structure is cumbersome to operate when taking off the watch.

[0004] Another method is to connect the two watch straps magnetically, but this is not secure, is prone to falling off, and is not compatible with watch straps made of materials such as titanium and stainless steel.

[0005] Therefore, existing technologies need to be improved. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a watch strap connection structure that is simple and quick to remove the watch strap and is compatible with watch straps of different materials.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] In a first aspect, this utility model proposes a watch strap connection structure, which includes an upper shell, a lower shell disposed below the upper shell, and a button buckle disposed between the upper shell and the lower shell to connect the upper shell and the lower shell together;

[0009] The upper housing is provided with a first strap connection part, and the lower housing is provided with a second strap connection part. After pressing the button buckle, the upper housing and the lower housing are separated.

[0010] In some embodiments, the button buckle includes two L-shaped button bodies disposed opposite to each other, the L-shaped button bodies being housed within the upper housing and being able to slide within the upper housing.

[0011] In some embodiments, one end of the L-shaped button body is provided with a button portion, which protrudes from the side wall of the upper housing, and the other end of the L-shaped button body is provided with a hook, which is fastened to the lower housing.

[0012] In some embodiments, the upper housing is provided with a receiving cavity with an opening at the lower end for receiving two L-shaped button bodies, and the two opposite sidewalls of the upper housing are provided with button holes for exposing the button portions of the two L-shaped button bodies.

[0013] In some embodiments, the button buckle further includes a reset elastic member housed in the upper housing, with both ends of the reset elastic member abutting against the two L-shaped button bodies respectively, and the reset elastic member sliding the two L-shaped button bodies that have been pressed inward to reset outward.

[0014] In some embodiments, the lower housing includes a button buckle plate with a fastening hole, and the hook of the L-shaped button body extends into the fastening hole and fastens to the button buckle plate.

[0015] In some embodiments, the lower housing further includes a strap passage cavity and a second strap connection portion arranged sequentially below the button buckle plate, wherein the strap can be passed through the strap passage cavity and the bottom of the strap is connected to the second strap connection portion.

[0016] In some embodiments, the second strap connection portion includes a bottom buckle plate disposed on the button buckle plate and located at the bottom of the strap passage cavity, and an engagement protrusion disposed on the bottom buckle plate, the engagement protrusion being used to engage with the strap.

[0017] In some embodiments, the bottom buckle plate is rotatably connected to the button buckle plate, for quickly locking or releasing the watch strap inside the strap passage cavity.

[0018] Secondly, this utility model also proposes a wearable electronic device, which includes the aforementioned watch strap connection structure.

[0019] It should be understood that, within the scope of this utility model, the above-mentioned technical features of this utility model and the technical features specifically described below (such as embodiments) can be combined with each other to form new or preferred technical solutions. Due to space limitations, they will not be described in detail here.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The device features a detachable upper and lower housing design. The upper housing connects to one watch strap, and the lower housing connects to another. The upper and lower housings are connected by a snap-on clasp. To remove the watch strap, simply press the snap-on clasp, and the upper and lower housings will detach, thus separating the two watch straps. This allows for quick and easy removal of smartwatches and other electronic devices from the wrist. Furthermore, because each housing has its own strap connection point instead of the magnetic connection used in existing technology, this strap connection structure is compatible with watch straps made of materials such as titanium and stainless steel.

[0038] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0039] Example 1, please refer to Figures 1 to 3This utility model proposes a watch strap connection structure 100, including an upper housing 1, a lower housing 2 disposed below the upper housing 1, and a button buckle 3 disposed between the upper housing 1 and the lower housing 2 to connect the upper housing 1 and the lower housing 2. The upper housing 1, lower housing 2, and button buckle 3 of the watch strap connection structure 100 can be made of materials such as metal or plastic. Preferably, in this embodiment, the upper housing 1, lower housing 2, and button buckle 3 are made of metal. A portion of the button buckle 3 is connected to the upper housing 1, and another portion is connected to the lower housing 2. The connection method between the button buckle 3 and the upper housing 1 and lower housing 2 can be a detachable plug-in, snap-fit, or fastening.

[0040] The upper housing 1 is provided with a first strap connecting part 11, and the lower housing 2 is provided with a second strap connecting part 21. The first strap connecting part 11 is used to connect one strap 100 of a wearable electronic device, and the second strap connecting part 21 is used to connect another strap 200 of the wearable electronic device. Wearable electronic devices include smartwatches, wristbands, and other electronic devices. Figure 2 As shown, one end of the short watch strap 200 on the left is connected to the upper housing 1, and the other end is connected to the dial; one end of the long watch strap 200 on the right is inserted into the lower housing 2 and connected to the lower housing 2, and the other end is connected to the dial.

[0041] In this invention, the first strap connecting part 11, the second strap connecting part 21, and the strap 200 can be connected by snap-fit ​​connection, welding, or other methods. In this embodiment, the strap 200 and the upper housing 1 are made of the same material, and the upper housing 1 and the strap 200 are fixed by welding at the first strap connecting part 11. Specifically, in this embodiment, the first strap connecting part 11 is a welding groove provided on the side wall of the upper housing 1.

[0042] like Figure 3 As shown, in the watch strap connection structure 100 of this utility model, the upper housing 1 and the lower housing 2 separate after the button buckle 3 is pressed. In this embodiment, pressing the button buckle 3 inward disengages the connection between the upper housing 1 and the lower housing 2, thus separating the two watch straps 200, making it easy to quickly remove the wearable electronic device. The operation is simple and quick. Similarly, when wearing the wearable electronic device, simply align the upper housing 1 with the watch strap 200 and the lower housing 2, so that the button buckle 3 connects the upper housing 1 and the lower housing 2 together to complete the wearing process.

[0043] Meanwhile, in this embodiment, the upper housing 1 is provided with a first strap connecting part 11 and the lower housing 2 is provided with a second strap connecting part 21, which are respectively connected and fixed to the two straps 200. This avoids the defect of magnetic connection being easy to detach and unsafe, and can also be compatible with straps of various materials.

[0044] Preferably, such as Figure 4 and Figure 5 As shown, the button buckle 3 includes two L-shaped button bodies 31 arranged opposite each other. The L-shaped button bodies 31 are housed within the upper housing 1 and can slide within the upper housing 1. Figure 4 As shown in the figure, an L-shaped button body 31 is provided on each of the two opposite sides of the upper housing 1 in this embodiment. The two L-shaped button bodies 31 connect the upper housing 1 and the lower housing 2 together, so that the force between the upper housing 1 and the lower housing 2 is balanced, and it is also convenient to press to unlock.

[0045] In this embodiment, the two L-shaped button bodies 31 slide inward or outward within the upper housing 1. When sliding inward, the upper housing 1 is separated from the lower housing 2, and when sliding outward, the upper housing 1 is connected to the lower housing 2.

[0046] Preferably, the button buckle 3 in this embodiment further includes a reset elastic member 32 housed within the upper housing 1. The two ends of the reset elastic member 32 abut against the two L-shaped button bodies 31 respectively. The reset elastic member 32 slides the two L-shaped button bodies 31, which have been pressed inward, back to their original position. That is, when both L-shaped button bodies 31 are pressed inward in this embodiment, the reset elastic member 32 is also compressed simultaneously. Thus, when the external force is released, the two L-shaped button bodies 31 are pushed outward by the elastic force of the reset elastic member 32 and reset. This eliminates the need for manual reset of the L-shaped button bodies 31.

[0047] Preferably, the reset elastic element 32 in this embodiment can be a spring steel shaft, which has high elasticity and is not easily fatigued or deformed.

[0048] As one implementation method, such as Figure 4 and Figure 6 As shown, in this embodiment, the L-shaped button body 31 has a button portion 311 at one end, which protrudes from the side wall of the upper housing 1. The other end of the L-shaped button body 31 has a hook 312, which engages with the lower housing 2. That is, in this embodiment, the button portion 311 of the L-shaped button body 31 extends laterally from the side wall of the upper housing 1, while the hook 312 extends downward from inside the upper housing 1 and engages with the lower housing 2. This L-shaped structural design allows one end to hook the upper housing 1 and the other end to hook the lower housing 2, thus connecting the upper and lower housings together. Simultaneously, pressing the button portion 311 inward causes the hook 312 to slide inward as well, disengaging it from the lower housing 2. Therefore, the structural design of the L-shaped button body 31 allows the upper housing 1 and lower housing 2 to detach quickly, and the operation is extremely simple.

[0049] Preferably, the inner side of the L-shaped button body 31 is also provided with an elastic element mounting groove 313. The elastic element mounting groove 313 facilitates the storage and limiting of the end 321 of the reset elastic element 32, and facilitates the installation and fixing of the reset elastic element 32.

[0050] Furthermore, such as Figure 4 and Figure 5 As shown, a baffle 4 is also provided inside the upper housing 1 below the reset elastic member 32. The baffle 4 is connected to the upper housing 1 by screws 5. The baffle 4 and the upper housing 1 together limit the upper and lower sides of the reset elastic member 32 to prevent the reset elastic member 32 from dislodging downward.

[0051] Specifically, such as Figure 7 As shown, in this embodiment, the upper housing 1 is provided with a receiving cavity 12 with an opening at the lower end for receiving two L-shaped button bodies 31. The two opposite sidewalls of the upper housing 1 have button holes 13 to expose the button portions 311 of the two L-shaped button bodies 31. In this embodiment, the bent body of the L-shaped button body 31 and the hook 312 are both located within the receiving cavity 12 of the upper housing 1. Simultaneously, the hook 312 extends downward from the opening at the lower end of the receiving cavity 12 to engage with the lower housing 2. Preferably, the top wall inside the upper housing 1 is also provided with screw holes 14 for connection and fixation with the baffle 4. Preferably, the top wall inside the upper housing 1 is also provided with a slot 15 for accommodating the reset elastic element 32. In this embodiment, the two button holes 13 are respectively located on the left and right sidewalls of the upper housing 1, while the first strap connecting portion 11 is located on the front sidewall of the upper housing 1.

[0052] like Figure 8 As shown, the lower housing 2 of this embodiment includes a button buckle plate 22, on which a fastening hole 221 is provided. The hook 312 of the L-shaped button body 31 extends into the fastening hole 221 and fastens with the button buckle plate 22. Preferably, the button buckle plate 22 of this embodiment is an inverted C-shaped plate. The top wall of the inverted C-shaped plate can be used to fasten with the button buckle 3, while the cavity below the top wall of the inverted C-shaped plate can be used to accommodate the watch strap 200.

[0053] In this embodiment, the fastening hole 221 is opened on the top wall of the button buckle plate 22. The hook 312 of the button buckle 3 extends into the fastening hole 221 on the top wall of the button buckle plate 22 and fastens with the top wall of the button buckle plate 22, thereby pulling the lower housing 2 upward. At the same time, since the button buckle 3 is embedded in the upper housing 1, the button buckle 3 pulls the lower housing 2 and connects the upper housing 1 and the lower housing 2 together.

[0054] Furthermore, such as Figure 8 As shown, the lower housing 2 of this embodiment also includes a strap passage cavity 23 and a second strap connecting part 21 sequentially arranged below the button buckle plate 22, as shown. Figure 9 As shown, the watch strap 200 can be inserted into the watch strap passage cavity 23, and the bottom of the watch strap 200 is connected to the second watch strap connecting part 21. In this way, the lower housing 2 can be fitted with the watch strap 200 in a through-hole manner. This not only serves as a watch strap connection but also allows for adjustment of the length of the watch strap 200 connection to suit different users. For example, when adjusting the connection length of the watch strap 200, the length of the watch strap 200 extending into the watch strap passage cavity 23 is adjusted. Once the appropriate length is reached, the watch strap 200 is then connected and fixed using the second watch strap connecting part 21.

[0055] Specifically, such as Figure 8 As shown, the second strap connection portion 21 includes a bottom buckle plate 24 disposed on the button buckle plate 22 and located at the bottom of the strap passage cavity 23, and an engaging protrusion 25 disposed on the bottom buckle plate 24, the engaging protrusion 25 being used to engage with the strap 200. Figure 9 As shown, the bottom of the watch strap 200 is provided with a slot 201. When the watch strap 200 is inserted into the watch strap passage cavity 23, the fitting protrusion 25 of the bottom buckle plate 24 is inserted upward into the slot 201 of the watch strap 200, which can fix the watch strap 200 and prevent it from being pulled at will.

[0056] Furthermore, such as Figure 10 As shown, in this embodiment, the bottom buckle plate 24 is rotatably connected to the button buckle plate 22, used to quickly engage or disengage the watch strap 200 within the watch strap passage cavity 23. The bottom buckle plate 24 is rotatable, facilitating the quick engagement and disengagement of the engaging protrusion 25 and the watch strap 200 slot 201, greatly simplifying the adjustment of the watch strap 200's connection length. When adjusting the length of the watch strap 200, as... Figure 10 As shown, simply move one end of the bottom buckle plate 24 downwards so that the fitting protrusion 25 moves downwards and disengages from the slot 201 of the watch strap 200. Then pull the watch strap 200 in the watch strap passage cavity 23 and adjust it to a suitable length. Finally, rotate the bottom buckle plate 24 upwards so that the fitting protrusion 25 is inserted into the slot 201 of the watch strap 200.

[0057] In this embodiment, as Figure 5 As shown, a first pivot hole 222 is provided on the side wall of the button buckle plate 22 of the lower housing 2, and a second pivot hole 241 is provided on the bottom buckle plate 24 of the lower housing 2. The pivot 26 passes through the first pivot hole 222 and the second pivot hole 241, so that the bottom buckle plate 24 and the button buckle plate 22 are rotatably connected.

[0058] Preferably, such as Figure 10 As shown, a pointed plate 243 is provided at one end of the bottom buckle plate 24 away from the second pivot hole 241. The pointed plate 243 is thinner than the bottom buckle plate 24, so that a pointed tip is formed at the end of the bottom buckle plate 24, which facilitates the movement of the bottom buckle plate 24.

[0059] Furthermore, such as Figure 10 As shown, the outer side wall of the bottom buckle plate 24 is provided with a locking block 242, and correspondingly, the inner side wall of the button buckle plate 22 is provided with a notch 223, into which the locking block 242 can be engaged. Thus, when the bottom buckle plate 24 rotates upwards, its engaging protrusion 25 engages with the watch strap 200, and simultaneously the locking block 242 of the bottom buckle plate 24 engages with the notch 223 of the button buckle plate 22, further serving a fixing and limiting function to prevent the engaging protrusion of the bottom buckle plate 24 from disengaging from the watch strap 200 during use.

[0060] This embodiment also proposes a wearable electronic device (not shown) including the aforementioned strap connection structure 100. Because the wearable electronic device has the aforementioned strap connection structure 100, the detachment and connection of the two straps 200 of the wearable electronic device in this embodiment are simple and quick, facilitating the rapid removal or placement of the wearable electronic device from the user's hand.

[0061] The above description is merely an example to clearly illustrate the present utility model and is not intended to limit the patent scope of the present utility model. It is impossible to exhaustively list all the embodiments here. All equivalent structural transformations made using the content of the technical solution of the present utility model under the concept of the present utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
