[0002] In the current method of measuring the distance between a live terminal and a top cover of a motor vehicle, a measuring column is vertically fixed near the live terminal, and a movable plate is slidably fitted onto the measuring column, forming an adjustable distance measuring mechanism. The measuring column surface is marked with graduations, with the zero mark located on the lower end face. The distance data is directly obtained by reading the graduations after the movable plate slides into contact with the top cover. Simultaneously, a perforated reflector is installed at one end of the movable plate, allowing observation of the contact state between the lower surface of the movable plate and the cover plate through reflection, thus avoiding measurement errors caused by blind spots. This method is cumbersome, requires multiple measurements, and is time-consuming. Utility Model Content

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0012] like Figures 1 to 2 As shown, a distance measuring device for the distance between the live terminals and the top cover of a battery factory vehicle is used during vehicle inspection to measure the distance between the live terminals and the top cover to determine whether the inspected vehicle meets the specified requirements. The device's structural design includes a detachable and connected top cover 1 and a base 2. The base 2 is hollow, with its hollow cavity divided into two chambers. Each chamber contains a plastic sealed bag filled with a different liquid that reacts and foams, and each chamber also serves to limit the movement of the liquid-filled plastic sealed bag. A scraper 3 is movably connected to the side of the top cover 1 closest to the hollow cavity of the base 2, and the scraper 3 is movably positioned within the hollow cavity of the base 2. By rotating the scraper 3, the two plastic sealed bags containing different liquids placed in the two chambers of the base 2 are broken, allowing the liquids flowing out of the plastic sealed bags to mix and foam.

[0013] Meanwhile, a scraper mounting seat is provided at one end of the upper cover 1 near the base 2. One end of the scraper mounting seat is movably placed in the hollow cavity of the base, and the scraper 3 is installed and connected to the scraper mounting seat by bolts. A rotating shaft is connected to the end of the scraper mounting seat away from the scraper. The other end of the rotating shaft passes through the upper cover through a bearing and is connected to a rotating head 11. The rotating head 11 has a hole for limiting rotation.

[0014] In this embodiment, when it is necessary to inspect the distance between the live terminals of a vehicle and the upper cover, the scraper 3 is rotated to break the plastic sealed bags containing different liquids placed in the two chambers of the base 2, allowing the liquids flowing out of the plastic sealed bags to mix and foam. During this period of mixing but before foaming, the measuring device is installed at the end of the live terminal, and then a few minutes are waited. During these few minutes, other vehicles can be inspected using another measuring device, allowing for seamless connection of inspection time without the need for inspection personnel to operate and wait. This achieves the purpose of saving costs and improving inspection efficiency.

[0015] It should be noted that the two hollow compartments of the base 2 are intended to hold two liquids sealed in plastic bags: polyurethane foam adhesive A and B; alternatively, they can hold three materials: adhesive A, adhesive B, and a mixture of calcium bicarbonate and citric acid powder placed in the compartments. When the plastic bags in the two compartments of the base 2 are broken by rotating the scraper 3, the two foaming liquids, or any multiple foaming liquids that can react, are allowed to mix. After a certain period of time, foaming and curing occur. Then, based on the measuring scale set on the measuring device (described in the following embodiment), a simple calculation is performed to determine whether the distance between the live terminal and the upper cover plate meets the requirements.

[0016] Furthermore, the end of the base 2 away from the top cover 1 is connected to a mounting head 21 for inserting and limiting the terminal end; the mounting head 21 is "bonded" to the bottom end of the base 2 or the mounting head 21 is made of a material that is easy to separate from the base 2 and is connected; by installing the mounting head 21 on the end of the terminal, the position of the measuring device is corrected, and the liquid in the measuring device is allowed to foam and solidify.

[0017] Meanwhile, a telescopic rod 4 is installed in the hollow cavity of the base 2 (the telescopic rod 4 can freely extend and retract, and is located at the edge of the hollow cavity of the base 2). One end of the telescopic rod 4 is threaded to the bottom end face of the hollow cavity of the base 2, and the other end is threaded to the end face of the upper cover 1 near the base 2. The telescopic rod 4 serves as a "guide" to push the upper cover 1 upward during the foaming reaction, so as to abut against the bottom end face of the upper cover plate. After the measuring device is placed, wait a few minutes and then remove the measuring device from the terminal. The outer wall of the upper cover 1 and the outer wall of the base 2 are respectively provided with measuring scales; the telescopic rod 4 is also provided with measuring scales. By simply calculating the "scale values ​​between the three and simple substitutions", the obtained value is compared with the allowable value to determine whether the requirements are met. The calculation method is roughly described as follows: 1. The outer shell scale value a of the upper cover 1 (the distance from the bottom of the outer wall of the upper cover 1 to the top of the outer wall of the upper cover 1, i.e., the thickness of the upper cover 1 is a). 2. The outer shell scale value b of base 2 (the distance from the bottom of the outer wall of base 2 to the top of the outer wall of base 2, i.e., the thickness of base 2 is b). 3. After the foaming agent in the base 2 has solidified, the telescopic movable rod 4 rises to the scale value c. Alternatively, the distance between the top of the measuring device cover 1 and the bottom of the base 2 after the foaming and solidification is measured as d. Assumption: The measured distance e from the live terminal to the upper cover plate; e = a + b + c; (when the scale value c of the telescopic lever 4 rising can be easily read); or: e=d; (When it is inconvenient to read the scale value c of the telescopic rod 4 rising, directly measure the relative distance d between the top of the measuring device cover 1 and the bottom of the base 2). Both of the above methods can be used to measure the distance e between the live terminal and the upper cover through simple calculations and substitutions. By comparing the e value with the distance range allowed by the inspection regulations, it can be determined whether the inspected vehicle meets the specified requirements.

[0018] It should be noted that after the mounting head 21 is connected to the end of the live terminal, the bottom end of the base 2 and the top end of the live terminal are on the same horizontal plane, so it is not necessary to measure the distance between the mounting head 21 and the top end of the live terminal.

[0019] Furthermore, the following example illustrates the general implementation process of the measurement: When working, first insert an electric screwdriver or other manual lever tool into the slotted hole of the rotating head 11, and rotate the rotating head 11 to drive the scraper 3 to rotate, so that the scraper 3 cuts the foaming liquid in each plastic bag, releases the contents, and achieves the purpose of rapid stirring. Then, the measuring device is placed on the live terminal of the battery in the factory vehicle, and the battery factory vehicle cover is closed. At this time, the substance in the measuring device begins to react and foam. The foam will push up the cover 1 until the cover 1 contacts the battery factory vehicle cover. Since it cannot move upward, the foam will expand in all directions (in order to prevent contamination, a folded plastic bag can be placed on the outside of the cover and base of the measuring device). The expansion will end within 3 minutes, and the foam will solidify within 5 minutes without deformation. After 5 minutes, open the factory vehicle cover, remove the expanded measuring device, and directly read the scale value c of the rise of the telescopic rod 4. Calculate the distance e between the bottom of the base 2 and the top of the cover 1 at this time (or measure the distance e between the bottom of the base and the top of the cover with calipers) to obtain the final dimensions.

[0020] Since the height of the entire device (excluding the groove size) is only 7mm, which is more than 10mm and 15mm higher than the inspection requirements, the device can meet the inspection requirements and the data is accurate.

[0021] Because the materials used in this measuring device are readily available, the manufacturing cost is low, and it is easy to use, it greatly shortens the testing steps and time compared to the traditional "multiple manual" testing.
