[0032] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0033] The prior art has a technical problem that there is no detection device for detecting the actual usage limit value of the door opening strip.

[0034] To this end, the present application provides a door opening strip rebound amount detection device for detecting the rebound amount of a door opening strip, which is characterized by comprising:

[0035] A base, wherein a reference surface is arranged on the base;

[0036] A fixing assembly, wherein the fixing assembly is used to install the door opening strip, and after the door opening strip is installed, the distance between the bottom surface of the door opening strip and the reference surface is constant;

[0037] A compression component, the compression component is located above the fixing component, and the compression component is close to or away from the fixing component to achieve compression and rebound of the door opening strip;

[0038] A measuring component is located at one side of the fixing component; wherein, during the compression and rebound process of the door opening strip, the measuring component is used to measure the distance between the top of the door opening strip and the reference plane.

[0039] Example:

[0040] The door hole strip rebound detection device is used to detect the rebound amount of the door hole strip, which is installed in the gap between the door and the side panel. During the door opening and closing process, the door hole strip will compress and rebound to play a buffering role between the door and the side panel, and the rebound amount of the door hole strip after compression is an important indicator to measure its fatigue level. If the rebound amount of the door decreases, it means that the door hole strip has reached its limit of use and needs to be replaced. The present application reflects the rebound amount of the door hole strip by detecting the height of the door hole strip after the door hole strip rebounds. If the height of the door hole strip decreases as a whole, it means that the rebound amount of the door hole strip also decreases, further indicating that the door hole strip has reached its limit of use.

[0041] Attached Figure 1 This is a structural diagram of the vehicle door opening rebound detection device of the present application. Figure 1As shown, the door opening strip rebound detection device includes a base 200, which is arranged at the bottom of the detection device. The base 200 is provided with a foot at the bottom, and the foot is installed at the bottom of the base 200 to lift the base 200 to protect other components arranged on the base 200.

[0042] The upper surface of the base 200 is provided with a reference plane 210. The reference plane 210 is a reference for detecting the height of the door opening strip 100, and the height of the door opening strip 100 relative to the reference plane 210 is the actual height of the door opening strip 100. Further, the reference plane 210 is a horizontal plane.

[0043] Please refer to the attached Figure 1 As shown, the door hole profile rebound amount detection device further includes a fixing assembly 300, which is used to install the door hole profile 100. After the door hole profile 100 is installed, in order to ensure the accuracy of the height measurement of the door hole profile 100, it is necessary to ensure that the distance between the bottom surface of the door hole profile 100 and the reference surface 210 is constant. In one embodiment, after the door hole profile 100 is installed, the bottom surface of the door hole profile 100 abuts against the reference surface 210, that is, the distance between the bottom surface of the door hole profile 100 and the reference surface 210 is zero.

[0044] The fixing assembly 300 includes a fixing plate and a fixing fixture. The fixing plate is provided with a mounting surface, the mounting surface is located at the upper surface of the fixing plate, and the mounting surface is provided with a fixing fixture. The fixing fixture is used to install the door opening strip 100. The fixing fixture is provided on the fixing plate, and the fixing plate is installed on the reference surface 210. Therefore, after the door opening strip 100 is installed, the bottom surface of the door opening strip 100 abuts against the mounting surface. Furthermore, the distance between the mounting surface and the reference surface is constant to ensure the accuracy of the height measurement of the door opening strip 100. In one embodiment, the mounting surface and the reference surface 210 are on the same plane.

[0045] Among them, the base 200 is provided with a mounting hole 220, and the mounting hole 220 is formed by extending downward from the reference surface 210. The mounting hole 220 is detachably connected to the fixing plate 310, that is, the fixing plate 310 can be located in the mounting hole 220, and can also be taken out from the mounting hole 220 to achieve the replacement of the fixing component 300. In one embodiment, the mounting hole 220 and the fixing plate 310 are both rectangular parallelepipeds. When the fixing plate 310 is located in the mounting hole 220, the reference surface 210 and the mounting surface 311 are on the same plane. Further, when the fixing plate 310 is located in the mounting hole 220, the reference surface 210 and the mounting surface 311 are on the same horizontal plane.

[0046] Please refer to the attached Figure 1As shown, the door hole strip 100 rebound detection device also includes a compression component 400, which is used to compress the door hole strip 100, and continuously compress the door hole strip 100 and measure its height, and the measured height of the door hole strip 100 is counted. If the height of the door hole strip 100 decreases significantly, it is judged that the rebound amount of the door hole strip 100 is insufficient, and the door hole strip 100 needs to be replaced to prevent the door from not getting enough buffer when opening and closing. In one embodiment, when the height of the door hole strip 100 decreases within the range of 10%-30% of the original height of the door hole strip 100, the rebound amount of the door hole strip 100 is also within the normal range, and the door hole strip 100 can continue to be used. Among them, the original height of the door hole strip 100 refers to the height of the door hole strip 100 when it is not used.

[0047] The compression assembly 400 includes a column 420, which is vertically arranged on the base 200. Furthermore, the column 420 is arranged perpendicularly to the reference plane 210, and the column 420 is a long strip structure. The compression assembly 400 also includes a driving device 410 and a compression plate 430, and the compression plate 430 is slidably connected to the column 420 through a sliding device. In one embodiment, the sliding direction of the compression plate 430 is arranged perpendicularly to the reference plane 210, and the compression plate 430 is arranged parallel to the reference plane 210. The sliding device includes a sliding groove and a sliding protrusion, and the sliding groove and the sliding protrusion are arranged along the length direction of the column 420, and the length direction of the column 420 is arranged perpendicularly to the reference plane 210. The sliding groove is arranged on one of the column 420 or the compression plate 430, and the sliding protrusion is arranged on the other of the column 420 or the compression plate 430.

[0048] The output end of the driving device 410 is connected to the compression plate 430 to drive the compression plate 430 to move closer to or away from the fixing assembly 300 along the column 420. In one embodiment, the driving device 410 is a telescopic cylinder. The compression assembly 400 further includes a top plate 440, and the telescopic cylinders are respectively disposed between the top plate 440 and the compression plate 430, and are respectively connected to the top plate 440 and the compression plate 430.

[0049] Please refer to Figure 1 As shown, the rebound detection device for the door hole strip 100 further includes a measuring component 500, which is located on one side of the fixing component 300. When the door hole strip 100 is compressed or relaxed by the compression component 400, the door hole strip 100 is compressed or rebounded at the same time, and the measuring component 500 synchronously measures the distance between the top of the door hole strip 100 and the reference surface 210. After the door hole strip 100 is installed, the bottom surface of the door hole strip 100 abuts against the installation surface 311, and the installation surface 311 and the reference surface 210 are in the same plane. Therefore, the distance between the top of the door hole strip 100 and the reference surface 210 is the height of the door hole strip 100.

[0050] In one embodiment, the measuring component 500 is an infrared measuring device, which includes a transmitter and a receiver, which are respectively arranged on both sides of the fixed tooling, and the height of the door opening strip 100 is further determined by the reception status of the infrared receiver.

[0051] In one embodiment, the measuring component 500 is a photoelectric distance meter.

[0052] The driving assembly is connected to the measuring assembly 500, and the measuring assembly 500 simultaneously measures the distance between the compression plate 430 and the fixing assembly 300 to determine the amount of compression of the door opening strip 100 by the compression assembly 400. That is, the measuring assembly 500 simultaneously controls the amount of downward pressure of the compression plate 430, so that the downward pressure distance of the compression plate 430 is consistent each time, thereby ensuring the fairness of the experiment. In one embodiment, the downward pressure of the compression plate 430 is 40%-60% of the original height of the door opening strip 100 after contacting the original height of the door opening strip 100.

[0053] In one embodiment, the measuring assembly 500 is vertically arranged with respect to the reference plane 210, and has a recording module therein, which is used to record the original height of the door opening strip 100 and the real-time height of the door opening strip 100 during detection. The recording module is connected to the data output module to output the detection information.

[0054] In one embodiment, the measuring component 500 further includes a display module 510 , and the display module 510 is used to display the detection information.

The door opening strip 100 can be divided into multiple structures according to different installation methods, and according to different structures of the door opening strip 100, the fixing assembly 300 of the door opening strip 100 can also be divided into multiple structures. Figure 2 The figure shows one structure of the fixing assembly 300, wherein the fixing tooling includes a first protrusion 321 and a second protrusion 322 arranged along a first direction, and the first protrusion 321 and the second protrusion 322 are arranged at intervals along the second direction to form a fixing groove 323 located between the first protrusion 321 and the second protrusion 322, and the bottoms of the first protrusion 321 and the second protrusion 322 are connected to the fixing plate 310, and the first protrusion 321 and the second protrusion 322 are both long strip structures.

[0056] In one embodiment, the first protrusion 321 and the second protrusion 322 are disposed in parallel.

Figure 3 The figure shows another structure of the fixing assembly 300, in which the fixing tool includes a mounting plate 324, and the mounting plate 324 is arranged on the mounting surface 311 of the fixing plate 310. A mounting groove 325 extending along the first direction is arranged in the mounting plate 324, and the mounting groove 325 is formed by extending downward from the upper surface of the mounting plate 324. A clamping groove 326 is formed on both sides of the mounting groove 325 along the second direction, and the clamping groove 326 is connected to the mounting groove 325. The clamping groove 326 is arranged on the upper surface of the mounting plate 324, and the size of the clamping groove 326 in the second direction is larger than the size of the mounting groove 325 in the second direction to form a convex structure.

[0059] In one embodiment, the bottom of the mounting groove 325 is on the same horizontal plane as the mounting surface 311. Further, the mounting plate 324 is divided into a left plate 324-1 and a right plate 324-2 by the mounting groove 325.
