Description

Technical Field

[0001] This invention relates to the field of automotive technology, and more specifically to a device and method for detecting the static pressing force of an electric rear cover. Background Technology

[0002] With the rapid development of the automotive industry, electric tailgates are becoming increasingly common in passenger cars, presenting many new problems and challenges for production and R&D personnel. Electric tailgate systems achieve automatic opening and closing of the tailgate through control signals (such as in-vehicle switches, remote controls, proximity sensors, etc.). Electric tailgate systems feature anti-pinch, self-learning memory, and manual opening and closing functions.

[0003] The anti-pinch function is activated when the force applied to the power tailgate during closing exceeds the system's set standard closing force. The system then interprets this as an obstruction, stops, and initiates the flip-up function. This new feature brings new problems and challenges. The most prominent challenge is the tailgate's rebound caused by the anti-pinch function triggering when the power tailgate is closed.

[0004] Under reasonable conditions, the normal closing condition for the electric tailgate is: static pressing force < anti-pinch force. Here, anti-pinch force refers to the closing force required during the electric tailgate's closing process; this force is a system-set force. Static pressing force refers to the closing force required to manually close the tailgate to the first locking position under static conditions. Static pressing force is affected by multiple factors, including: tailgate matching status, vehicle dimensions at the rear panel stop, tailgate dimensions, and the compression load on the tailgate sealing strip. Therefore, when encountering tailgate rebound issues, it is necessary to measure the magnitude of the static pressing force. Since obtaining an accurate static pressing force value plays a decisive role in subsequent analysis and optimization, accurately measuring the static pressing force becomes particularly important.

[0005] Without auxiliary equipment, the static pressing force is measured as follows: Manually close the rear cover to the unlocked position, and use a force gauge to press against the outside of the rear cover as close to the lock as possible. To prevent the surface of the rear cover from being dented by the force gauge, a book can be placed between the force gauge and the rear cover. Ideally, the force gauge should be pressed in parallel with the rear cover lock. Then, slowly push the force gauge until it pushes the tailgate to the first locking position. Repeat the test procedure described above and take the average of the multiple data points.

[0006] However, the measurement method described above has the following drawbacks:

[0007] 1. When taking multiple measurements on the same vehicle, it is impossible to keep the force gauge pressed at the same point each time, which affects the accuracy of the data.

[0008] 2. The force gauge cannot be pressed in a direction that is completely parallel to the back cover lock, affecting the accuracy of the data.

[0009] 3. The item placed between the force gauge and the back cover will have a compression effect, which will affect the accuracy of the measurement data.

[0010] 4. Several vehicle body dimensions are among the factors affecting static indentation force, requiring measurement services to determine compliance. However, the measurement resources take approximately one day to arrive, slowing down the problem analysis process. Summary of the Invention

[0011] The purpose of this invention is to provide a simple and universally applicable method and component for detecting the static pressing force of an electric rear cover, ensuring that the force gauge is pressed in at the same point and the pressing direction is parallel to the rear cover lock, while also enabling rapid measurement of the vehicle body dimensions.

[0065] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0066] To improve the accuracy and efficiency of static pressing force measurement, this invention provides a static pressing force detection device for an electric rear cover, comprising: a measuring component and a detachable detection component 2. The measuring component is used to measure the static pressing force of the electric rear cover, effectively improving the accuracy of the static pressing force measurement; the detachable detection component 2 is used to measure the dimensions of the vehicle body, eliminating the need to wait for measurement resources and significantly improving measurement efficiency.

[0067] The measuring assembly includes a force gauge and an auxiliary measuring component 1. The auxiliary measuring component 1 is mounted on the electric rear cover and is used to adjust the pressing direction of the force gauge to be parallel to the rear cover lock, ensuring the accuracy of the measured data. The force gauge rests on the auxiliary measuring component 1 to measure the static pressing force.

[0068] In this embodiment, the auxiliary measurement component 1 includes a universal connecting plate 11 and an adjustable measurement angle mechanism 12. The universal connecting plate 11 is mounted on the electric rear cover, see [reference]. Figure 3 Specifically, the universal connector 11 is installed and fixed inside the license plate mounting hole. Because the spacing of the license plate mounting holes and the size of the rivets are consistent across all vehicle models, the universal connector 11 can be installed on various vehicle models. To reduce the weight of the universal connector 11, in one embodiment of the present invention, the universal connector 11 adopts an I-shaped design and is made of aluminum alloy. See [link to relevant documentation]. Figure 5 .

[0069] The adjustable measuring angle mechanism 12 is mounted on the universal connecting plate 11, see [reference]. Figure 4 The adjustable measuring angle mechanism 12 is used to adjust the pressing direction of the force gauge to ensure that the pressing direction of the force gauge is parallel to the rear cover lock. Figure 4 and Figure 6As shown, an adjustable measuring angle mechanism 12 according to an embodiment of the present invention includes a semi-circular disk 121, an angle ruler 122, a push rod 123, a first connecting member 124, a second connecting member 125, and an angle pointer 126. The angle ruler 122 is disposed on the first side of the semi-circular disk 121. A second sliding groove is formed on the inner side of the angle ruler 122 on the semi-circular disk 121, and the shape and size of the second sliding groove match those of the angle ruler 122. A through hole is formed at the center of the semi-circular disk 121. The push rod 123 is disposed on the second side of the semi-circular disk 121, and a first hole is formed at the lower end of the push rod 123, which is aligned with the through hole. The first connecting member 124 rotatably connects the semi-circular disk 121 and the push rod 123 from the first side of the semi-circular disk 121, passing sequentially through the through hole and the first hole. The push rod 123 has a second hole at the corresponding second groove. The second connector 125 connects the semi-disc 121 and the push rod 123 movably from the first side of the semi-disc 121 through the second groove and the second hole. The upper end of the push rod 123 extends toward the first side of the semi-disc 121, and the extension length is greater than the thickness of the semi-disc 121. An angle pointer 126 is connected from the first side of the semi-disc 121 to the upper end of the push rod 123. The angle pointer 126 points to the angle ruler 122. The top of the push rod 123 is provided with an anti-slip groove. The force gauge is placed on the anti-slip groove to measure the static pressing force, which can keep the force gauge pressed at the same point. In this embodiment, the first connector 124 is a rotating shaft screw, and the second connector 125 is a locking screw. In this embodiment, the anti-slip groove is a countersunk hole with an R7mm radius and a depth of 7mm. In this embodiment, the main principle of the adjustable measuring angle mechanism 12 is to allow the push rod 123 to rotate and adjust its angle on the semi-circular disk 121 using a rotating shaft screw and a locking screw. To reduce weight, the semi-circular disk 121 and the push rod 123 in this embodiment are made of aluminum alloy.

[0070] The specific steps for using the auxiliary measurement component 1 described above are as follows:

[0071] The first step is to push the push rod 123 to adjust the angle of the pressing point according to the design data of the back cover lock;

[0072] The second step is to close the back cover to the unlocked and non-clamped state;

[0073] The third step is to align the holes of the universal connector with the license plate mounting holes on the back cover.

[0074] Fourth step, tighten the fixing bolts to fix the universal connecting plate to the back cover;

[0075] Fifth step, press the force gauge into the anti-slip groove and use the force gauge to start measuring the force.

[0076] In this embodiment, the detachable testing assembly 2 includes a dial indicator 21, a locking member 22, a slide rail 23, and several fixing members 24. The dial indicator 21 includes a dial indicator body and a measuring rod, with the measuring rod passing through the dial indicator body. The dial indicator 21 extends through the lower end of the measuring rod to one end of the slide rail 23. The slide rail 23 has a graduated first groove for adjusting the measuring length of the dial indicator 21. The locking member 22 is connected to the slide rail 23 via the fixing members 24 and the first groove. The locking member 22 is used to adjust the angle of the dial indicator 21 and lock it in place. The locking member 22 is fixed to the tested object by the fixing members 24. Preferably, in this embodiment, the locking member is a 360° rotating locking block. The fixing members 24 are bolts.

[0077] Furthermore, the detachable testing assembly also includes at least one dial indicator extension link 25. The dial indicator extension link 25 is located at the lower end of the measuring rod and is used to extend the measuring range of the dial indicator.

[0078] In one embodiment, the detachable detection component 2 further includes:

[0079] A specific angle rotating link 26 and a first part end fixing base 27;

[0080] Alternatively, a 180° reverse measurement adjustment block 28 and a second part end fixing base 29.

[0081] Specifically, when the detachable testing assembly 2 further includes a specific angle rotating link 26 and a first part end fixing base 27, the first part end fixing base 27 is fixed to the tested body by a fixing member 24, the lower end of the specific angle rotating link 26 is movably connected to the upper end of the first part end fixing base 27, and the upper end of the specific angle rotating link 26 is connected to a locking member 22. The specific angle rotating link 26 is marked with an angle for adjusting the attitude of the dial indicator when the tested body is not at 90°.

[0082] When the detachable testing assembly 2 also includes a 180° reverse measurement adjustment block 28 and a second part end fixing base 29, the second part end fixing base 29 is fixed to the tested body by a fixing member 24. The lower end of the 180° reverse measurement adjustment block 28 is movably connected to the upper end of the second part end fixing base 29, and the upper end of the 180° reverse measurement adjustment block 28 is connected to a locking member 22. The 180° reverse measurement adjustment block 28 is used when measurements are required on both sides of the tested body.

[0083] It should be understood that in the detachable testing assembly 2, the dial indicator 21, locking element 22, slide rail 23, fixing element 24, and dial indicator extension rod 25 are standard block parts, while the specific angle rotation rod 26, first part end fixing base 27, 180° reverse measurement adjustment block 28, and second part end fixing base 29 are non-standard block parts. Therefore, standard and non-standard block parts can be selected and assembled together according to the actual situation to measure the step depth of the measured body. During measurement, the first part end fixing base 27 or the second part end fixing base 29 is fixed to the measured body with the fixing element 24 (generally using a through hole). Then, according to the actual situation of the measured body, the specific angle rotation rod 26 or the 180° reverse measurement adjustment block 28 is selected for connection. Then, the length of the slide rail 23 is selected according to the length of the measured body and fixed to the locking element 22 with the fixing element 24. Finally, the dial indicator 21 is used to measure the deviation of the measured body.

[0084] like Figure 7 and Figure 8 As shown, the present invention provides two specific embodiments of detachable detection components 2, which can be applied to different scenarios. In one embodiment, the detachable detection component 2 includes the dial indicator 21, a 360° rotating locking block, a slide rail 23, several fixing parts 24, a rotating connecting rod at a specific angle 26, and a first part end fixing base 27, as described above. See also... Figure 7 In another embodiment, the detachable testing assembly 2 includes the dial indicator 21 described above, a 360° rotating locking block, a slide rail 23, several fixing parts 24, at least one dial indicator extension rod 25, a 180° reverse measurement adjustment block 28, and a second part end fixing base 29. See also... Figure 8 Furthermore, the detachable detection component 2 described above can be used for measurements at other locations on the vehicle body, making it suitable for a wide range of applications. (See also...) Figure 10 .

[0085] An embodiment of the electric rear cover static pressing force detection device of the present invention further includes a dial indicator zero-position calibration platform 3 for zeroing the dial indicator 21 on the detachable detection component 2. Because the step depth of the tested body varies in actual production, it is necessary to first find the theoretical step depth of the tested body, then zero the dial indicator 21 based on this zero-position calibration platform 3, and finally measure the tested body with the zeroed dial indicator 21 to obtain the deviation value. Therefore, the dial indicator zero-position calibration platform 3 is an indispensable part and plays a very important role in the entire measurement process. In this embodiment, the dial indicator zero-position calibration platform 3 includes: a vernier caliper 31, a zero-position platform 32, a fixing pin 33, and a worktable 34. See [link to documentation]. Figure 9a The workbench 34 is used to place the detachable testing component 2 during calibration; see [reference]. Figure 9b and Figure 9cA vernier caliper 31 is located on one side of the worktable 34 and is used to measure the theoretical value of the step depth of the measured object. A zero-position stage 32 is slidably connected to the vernier caliper 31 and is used to zero the dial indicator 21. A fixing pin 33 is connected to the zero-position stage 32 to fix the position of the zero-position stage 32 on the vernier caliper.

[0086] This invention also provides a method for detecting the static pressing force of an electric rear cover, applied to the electric rear cover static pressing force detection device described above, such as... Figure 11 As shown, it includes:

[0087] Step S1: Measure the static indentation force of the defective vehicle using the measuring components;

[0088] Step S2: Determine the difference between the static pressing force and the anti-pinch force standard;

[0089] Step S3: Use the detachable inspection components to check the matching and quality of the rear cover and the body, check the quality of the final assembly parts, and check the quality of the electrical parts.

[0090] Step S4: Optimize and rework parts that do not meet the requirements;

[0091] Step S5: Measure the static pressing force of the defective vehicle using the measuring component. If the static pressing force is less than the anti-pinch force, proceed to step S6; otherwise, return to step S4.

[0092] Step S6, detection ends.

[0093] In step S3, the locations that need to be inspected for the vehicle body and rear cover are as follows: Figure 1a , 1b As shown in 2a and 2b. Figure 1b for Figure 1a Enlarged schematic diagram of the rear stop area B. Figure 2b for Figure 2a Enlarged schematic diagram of point C at the contact surface of the sealing strip and schematic diagram of section AA, where d represents the depth between the contact surface of the sealing strip and the outer plate.
