These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0039] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art.
[0040] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0041] like Figure 1 As shown, this application embodiment provides a measuring device, which includes a base 100 and a measuring mechanism 200. The base 100 is adapted to be fixed on the object to be measured. It should be noted that the object to be measured in this application embodiment can be, for example, a product with shock absorption function such as a scooter equipped with a shock absorption system. The base 100 can be plate-shaped and can be installed on the scooter's footboard.
[0042] The measuring mechanism 200 includes a first fixed support 210 and at least one measuring cup 220, with the first fixed support 210 mounted on the base 100. Thus, both the measuring cup 220 and the first fixed support 210 can move synchronously with the base 100 and the object being measured. The measuring cup 220 is detachably mounted on the first fixed support 210 and contains liquid. In some embodiments, the measuring cup 220 can be transparent, while the liquid is opaque. This makes it easier for users or measuring personnel to observe the amplitude of liquid movement within the measuring cup 220.
[0043] It should be noted that since the measuring cup 220 contains liquid, when the object under test travels over uneven terrain, the amplitude of the liquid's movement within the measuring cup 220 can reflect the vibration amplitude of the object, thereby determining the vibration damping effect of the damping system installed on the object. In other words, this embodiment of the application visualizes the vibration damping effect of the object under test, allowing measurement personnel and users to more intuitively understand the vibration damping effect. It should be understood that the measuring cup 220 may not be completely filled with liquid; that is, a certain cavity remains above the measuring cup 220, allowing the liquid to swirl within it.
[0044] The following is in conjunction with the appendix Figures 1 to 3 The details and functions of the measuring device provided in the embodiments of this application will be described in more specific and detailed manner.
[0045] like Figure 2 As shown, in some embodiments, the first fixed bracket 210 includes a first bracket 211 and a second bracket 212 disposed opposite to each other. The first bracket 211 is located on the base 100 and has at least one first through hole 2111. The second bracket 212 has at least one second through hole 2121, and the second through hole 2121 corresponds one-to-one with the first through hole 2111. The measuring cup 220 is located within the first through hole 2111 and the second through hole 2121. In this way, the first through hole 2111 and the second through hole 2121 can respectively position and restrict the measuring cup 220, preventing the measuring cup 220 from tilting and improving the reliability of the measuring device. It should be noted that during assembly, the bottom of the measuring cup 220 can first pass through the second through hole 2121 and then be inserted into the first through hole 2111. After the bottom of the measuring cup 220 is positioned, the top of the measuring cup 220 is subsequently limited within the second through hole 2121. Thus, the measuring cup 220 can be detachably installed, improving the assembly efficiency of the measuring cup 220 and making it easier to remove the measuring cup 220 from the first fixed bracket 210. In some embodiments, the first through hole 2111 and the second through hole 2121 are coaxial, and the axial direction of the first through hole 2111 and the axial direction of the second through hole 2121 are both perpendicular to the base 100. This ensures that the measuring cup 220 is in a vertical position and prevents the measuring cup 220 from tilting during vibration.
[0046] like Figure 2 As shown, in some embodiments, the first fixed bracket 210 further includes a rotating plate 213. The rotating plate 213 is located on the side of the second bracket 212 opposite to the first bracket 211. The first end of the rotating plate 213 is connected to the second bracket 212, and the second end of the rotating plate 213 can rotate around the first end. When the rotating plate 213 is in the first position, it abuts against the top of the measuring cup 220. When the rotating plate 213 rotates to the second position, it protrudes from the top of the measuring cup 220. It should be noted that when the rotating plate 213 abuts against the top of the measuring cup 220, it can limit the longitudinal direction of the measuring cup 220, preventing it from flying out of the second through hole 2121 during shaking, thus improving the reliability and stability of the measuring device. When the rotating plate 213 protrudes from the top of the measuring cup 220, it facilitates the removal of the measuring cup 220 from the first through hole 2111 and the second through hole 2121.
[0047] like Figure 2 As shown, the first end of the rotating plate 213 is rotatably connected to the second bracket 212, and the second end of the rotating plate 213 is engaged with the second bracket 212. This arrangement ensures that the second end of the rotating plate 213 can rotate around the first end, allowing the second end of the rotating plate 213 to be secured or separated from the second bracket 212. This not only allows for more flexible adjustment of the position of the rotating plate 213 but also prevents the rotating plate 213 from detaching from the first fixed bracket 210, thus facilitating the longitudinal positioning of the measuring cup 220 and making it easier to quickly remove the measuring cup 220 from the first fixed bracket 210.
[0048] like Figure 2 As shown, in some embodiments, the side of the second bracket 212 opposite to the first bracket 211 is connected to a first fixing post 214 and a second fixing post 215. The first end of the rotating plate 213 has a pin hole 2131, and the second end of the rotating plate 213 has a slot 2132. The measuring mechanism 200 also includes a first fixing member 230 and a second fixing member 240. The first fixing member 230 passes through the pin hole 2131 and is connected to the first fixing post 214, and the second fixing member 240 is connected to the second fixing post 215. When the rotating plate 213 is in the first position, a portion of the second fixing member 240 is engaged in the slot 2132. When the rotating plate 213 rotates to the second position, the second fixing member 240 separates from the slot 2132. It should be noted that the first fixing member 230 and the second fixing member 240 can be, for example, screws, bolts, or other similar components. Since the first end of the rotating plate 213 is connected to the second bracket 212 through the first fixing member 230, the rotating plate 213 can be prevented from detaching from the second bracket 212. Meanwhile, the position of the rotating plate 213 can be adjusted more flexibly by engaging the slot 2132 at the second end of the rotating plate 213 with the second fixing member 240.
[0049] like Figure 2As shown, in some embodiments, the first fixed support 210 further includes a background plate 218. The first support 211 and the second support 212 are located on the same side of the background plate 218, and the orthographic projection of the measuring cup 220 onto the plane of the background plate 218 is located within the background plate 218. It should be noted that the measuring cup 220 is generally transparent. By setting the background plate 218, it is easier for measuring personnel and users to clearly observe the liquid. It should be understood that the background plate 218 is a different color from the liquid, thereby improving the observation effect of the liquid.
[0050] like Figure 2 As shown, in some embodiments, the first fixing bracket 210 further includes a first side plate 216 and a second side plate 217 disposed opposite to each other, and the first bracket 211, the first side plate 216, the second bracket 212, and the second side plate 217 are connected in sequence. The two sides of the background plate 218 are respectively connected to the first side plate 216 and the second side plate 217. This improves the stability of the background plate 218 installation. It should be noted that the first bracket 211 and the second bracket 212 can be fixed to both ends of the first side plate 216 by bolts, and the first bracket 211 and the second bracket 212 can be fixed to both ends of the second side plate 217 by bolts.
[0051] Combination Figure 1 and Figure 3 As shown, in some embodiments, the measuring device further includes a camera 400, which is mounted on the base 100 and positioned opposite the first fixed bracket 210. The camera 400's imaging area is aligned with the measuring cup 220. It should be understood that the measuring cup 220 is located between the camera 400 and the background plate 218. It should be noted that the camera 400 can capture images of the measuring cup 220 to record the amplitude of liquid sloshing within the measuring cup 220 in real time. The camera 400 can be electrically connected to an electronic device and transmit the captured image or video data to the electronic device. The electronic device can generate a graph corresponding to the amplitude of liquid sloshing based on the captured image or video data, thereby providing testers with more accurate measurement data for accurate and effective improvement of the shock absorption system of the test object.
[0052] Combination Figure 1 and Figure 3As shown, in some embodiments, the measuring device further includes a clamping mechanism 300. The clamping mechanism 300 includes a first clamping member 310 and a second clamping member 320 disposed opposite to each other. The first clamping member 310 is mounted on the base 100, and the second clamping member 320 is movably connected to the first clamping member 310. The camera 400 is located between the first clamping member 310 and the second clamping member 320. The second clamping member 320 moves toward the first clamping member 310 to clamp the camera 400. The second clamping member 320 moves away from the first clamping member 310 to release the camera 400. It should be noted that the cooperation between the second clamping member 320 and the first clamping member 310 allows for more flexible fixation of the camera 400. Furthermore, since different sizes of cameras 400 can be adapted by changing the distance between the first clamping member 310 and the second clamping member 320, the applicability of the clamping mechanism 300 is improved, thus improving the applicability of the measuring device.
[0053] like Figure 3 As shown, in some embodiments, the clamping mechanism 300 further includes a third fixing member 330. The second clamping member 320 is provided with a mounting hole 321, and the first clamping member 310 is provided with a first blind hole 311 opening towards the mounting hole 321. The third fixing member 330 passes through the mounting hole 321 into the first blind hole 311. The portion of the sidewall of the third fixing member 330 located within the mounting hole 321 is a smooth surface, and the portion of the sidewall of the third fixing member 330 located within the first blind hole 311 is threaded. It should be noted that when the third fixing member 330 rotates relative to the first blind hole 311, the third fixing member 330 can drive the second clamping member 320 to move synchronously, thereby changing the distance between the first clamping member 310 and the second clamping member 320, thereby causing the clamping mechanism 300 to clamp or release the camera 400. It should be understood that since the portion of the sidewall of the third fastener 330 located within the mounting hole 321 is a smooth surface, the second clamping member 320 can be prevented from rotating due to the interaction force generated between it and the third fastener 330 when the third fastener 330 rotates relative to the first blind hole 311. In some embodiments, there is a gap between the portion of the third fastener 330 located within the mounting hole 321 and the wall of the mounting hole 321. Thus, the second clamping member 320 can be further prevented from rotating due to the interaction force generated between it and the third fastener 330 when the third fastener 330 rotates relative to the first blind hole 311.
[0054] like Figure 3As shown, in some embodiments, the first clamping member 310 has a second blind hole 312 and a third blind hole 313 opening towards the second clamping member 320. The second clamping member 320 has a fourth blind hole (not shown) and a fifth blind hole (not shown) opening towards the first clamping member 310. The second blind hole 312 and the fourth blind hole are opposite to each other, and the third blind hole 313 and the fifth blind hole are opposite to each other. The clamping mechanism 300 also includes a first guide post 340 and a second guide post 350, which are located on both sides of the third fixing member 330. The two ends of the first guide post 340 extend into the second blind hole 312 and the fourth blind hole, respectively, and the two ends of the second guide post 350 extend into the third blind hole 313 and the fourth blind hole, respectively. It should be noted that when the third fixing member 330 rotates relative to the first blind hole 311, the first guide post 340 and the second guide post 350 can position the movement direction of the first clamping member 310 to prevent the first clamping member 310 from rotating. It should be understood that when the third fixing member 330 rotates to move the second clamping member 320, the first guide post 340 and the second guide post 350 will not rotate. The portion of the first guide post 340 located within the second blind hole 312 can be threaded into the second blind hole 312, and the portion of the first guide post 340 located within the fourth blind hole has a smooth sidewall. The portion of the second guide post 350 located within the third blind hole 313 can be threaded into the third blind hole 313, and the portion of the second guide post 350 located within the fifth blind hole has a smooth sidewall. Thus, the first guide post 340 and the second guide post 350 will not rotate when the third fixing member 330 rotates, ensuring that the second clamping member 320 can move smoothly relative to the first clamping member 310.
[0055] like Figure 3 As shown, in some embodiments, the first end of the second clamping member 320 is movably connected to the first end of the first clamping member 310, the second end of the first clamping member 310 is bent toward the second clamping member 320, and the second end of the second clamping member 320 is bent toward the first clamping member 310. In this way, the bent portions of the first clamping member 310 and the second clamping member 320 can better secure the camera 400, preventing the camera 400 from detaching from the clamping mechanism 300.
[0056] In some embodiments, the clamping mechanism 300 further includes a fixing seat 370, which is located between the first clamping member 310 and the base 100, and is connected to both the first clamping member 310 and the base 100. By providing the fixing seat 370, the first clamping member 310 can be more stably mounted on the base 100. It should be noted that the first bracket 211 and the fixing seat 370 are respectively fixed to the base 100 by bolts.
[0057] like Figure 3As shown, in some embodiments, the clamping mechanism 300 further includes a fourth fixing member 360, which is connected to the second clamping member 320 and the third fixing member 330 respectively. It should be noted that the fourth fixing member 360 can keep the positions of the second clamping member 320 and the third fixing member 330 relatively fixed. For example, the outer wall of the third fixing member 330 may be provided with an annular groove, the second clamping member 320 may be provided with a corresponding mounting hole, the fourth fixing member 360 is perpendicular to the third fixing member 330, and one end of the fourth fixing member 360 passes through the mounting hole and is engaged in the annular groove. Thus, when the third fixing member 330 rotates relative to the first blind hole 311, the second clamping member 320 can move away from or towards the first clamping member 310 synchronously with the third fixing member 330.
[0058] In summary, the embodiments of this application employ a measuring device equipped with a measuring cup 220, which can present the shock absorption effect of the object under test in a visual manner, so that when the object under test moves, the measuring personnel and users can more intuitively understand the shock absorption effect of the object under test.
