Detailed Implementation
[0022] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.
[0023] Example 1
[0024] A smartwatch strap measurement and fixing fixture, see [reference] Figure 1 , Figure 2 The watch includes: a fixed base plate 1, a base 2, multiple strap clamping blocks 3, and a dial clamping block 4; the base 2 is fixedly mounted on the fixed base plate 1 by bolts. The fixed base plate 1 is made of 603 aluminum; the base 2 is made of POM (polyoxymethylene); the top corners of each strap clamping block 3 are rounded to avoid being too sharp. The strap clamping blocks 3 are made of 45# steel (high-quality carbon structural steel) and their surface is nickel-plated.
[0025] The base 2 has rectangular grooves 2-1 and multiple arc-shaped grooves 2-2. The number of arc-shaped grooves 2-2 corresponds to the number of protrusions on the smartwatch strap, used to position the smartwatch strap and facilitate its placement on the base 2. The rectangular grooves 2-1 facilitate the placement of the smartwatch dial on the base 2. A strap limiting block 2-3 is fixedly installed at the front end of the base 2 to limit the smartwatch strap. Multiple sets of mounting holes are symmetrically arranged on the base 2, each with a first strong magnet 5 fixedly installed. A second magnet is symmetrically arranged inside each strap pressing block 3. The first and second strong magnets magnetically attract each other to fix the smartwatch strap, thus achieving a seamless fit between the strap pressing block 3 and the upper surface of the smartwatch strap, ensuring no vibration of the smartwatch strap in the Z-axis direction. The number of first strong magnets 5 is determined by the length of the smartwatch strap; the longer the smartwatch strap, the more first strong magnets 5 are required.
[0026] Furthermore, the watch strap limiting block 2-3 is fixedly installed on the front end of the base 2 by bolts.
[0027] The dial pressing block 4 is bolted and installed directly above the arc-shaped groove 2-2 to press the smartwatch dial firmly. The dial pressing block 4 includes a main body 4-1, two upper support rods 4-2-1, and two lower support rods 4-2-2. The two upper support rods 4-2-1 and two lower support rods 4-2-2 are symmetrically fixed in the middle position of the main body 4-1. When the smartwatch dial is placed in the arc-shaped groove 2-2, the rear end of the upper support rod 4-2-1 is embedded in the upper side frame of the smartwatch dial, and the front end of the lower support rod 4-2-2 is embedded in the lower side frame of the smartwatch dial, thus pressing the smartwatch dial firmly. The dial pressing block 4 is made of 45# steel with a nickel-plated surface. The base 2 has a length of 210mm-250mm, preferably 218.5mm, which is suitable for most smartwatch straps on the market.
[0028] Furthermore, the fixed base plate 1 has multiple positioning holes 1-1 for fixing the fixed base plate 1 to the testing equipment via positioning pins; each positioning hole 1-1 is provided with a positioning bushing 1-2 to reduce friction and wear between the positioning pins and the fixed base plate 1, thereby improving the assembly accuracy and stability of the fixture. The positioning bushing 1-2 is made of copper, and the number of positioning holes 1-1 is preferably two.
[0029] A method for measuring and fixing a smartwatch strap includes the following steps:
[0030] Step 1: Place the smartwatch strap and smartwatch face into the rectangular groove 2-1 and the arc-shaped groove 2-2 respectively.
[0031] Step 2: Place the strap clamp 3 above the first strong magnet 5, and use the second strong magnet inside the strap clamp 3 to magnetically attract the first strong magnet 5 to fix the smart watch strap.
[0032] Step 3: Then, fix the dial pressing block 4 directly above the arc-shaped groove 2-2, so that the rear end of the upper support rod 4-2-1 is embedded in the upper side frame of the smart watch dial, and the front end of the lower support rod 4-2-2 is embedded in the lower side frame of the smart watch dial, which plays a pressing role on the smart watch dial.
[0033] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0034] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.
[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
