Description

Technical Field

[0001] The present invention relates to the technical field of automotive sunroof measurement, and particularly to a device for testing the pushing and pulling force of a sunshade curtain of an automotive sunroof. Background Art

[0002] Existing automobiles generally are equipped with sunroofs, and sunshade curtains are installed on the side of the sunroof close to the interior of the vehicle to prevent sunlight from shining into the vehicle through the sunroof. In order to ensure that the sunshade curtain of the sunroof is quiet, comfortable, and noiseless during manual pushing and pulling, and to make the sunshade curtain have the most comfortable pushing and pulling force, and to prevent the sunshade curtain of the sunroof from sliding under inertia when the vehicle brakes, it is necessary to test the pushing and pulling force of the sunshade curtain of the automotive sunroof, and only after passing the test can it enter the next process.

[0003] However, the existing tests for the pushing and pulling force of sunshade curtains are usually manual tests. Manual tests not only cannot accurately control factors such as the pushing and pulling speed and the pushing and pulling distance, resulting in low repeatability and reproducibility of test values and inaccurate test results, but also cannot adapt to large-scale measurements.

[0004] Chinese Patent CN213985489U (authorization announcement date: August 17, 2021) discloses a device for testing the pushing and pulling force of a sunshade curtain of an automotive sunroof, which includes a frame, a sliding assembly arranged on the frame, and the sunshade curtain can slide on the sliding assembly; a hooking test device for hooking and pulling the sunshade curtain and collecting the pushing force and pulling force when the sunshade curtain slides in the sliding groove; and a driving device connected to the test device for driving the test device to approach or move away from the sunshade curtain. Although this method can achieve automatic testing of the pushing and pulling force of the sunshade curtain of the sunroof, there is no buffer mechanism in the testing machine, resulting in large fluctuations in the measurement curve, low repeatability and reproducibility of test values, and inaccurate test results. Summary of the Invention

[0005] The purpose of the present invention is to provide a device for testing the pushing and pulling force of a sunshade curtain of an automotive sunroof, which can achieve the purpose of a stable measurement curve, high repeatability and reproducibility of test values, and accurate test results.

[0006] To achieve the above object, a push-pull force test device for a sunshade curtain of an automobile sunroof designed by the present invention includes a front-back push-pull cylinder, a vertical lifting cylinder, a push-pull force test mechanism, a first connecting member fixedly connecting the front-back push-pull cylinder and the vertical lifting cylinder, and a second connecting member fixedly connecting the vertical lifting cylinder and the push-pull force test mechanism; the first connecting member and the second connecting member are respectively arranged on both sides of the vertical lifting cylinder; wherein, the push-pull force test mechanism includes a push-pull head whose upper part abuts against the sunshade curtain handle, a connecting block arranged below the push-pull head, a lifting buffer mechanism connecting the push-pull head and the connecting block, a connecting bracket arranged on the side of the connecting block, a push-pull buffer mechanism and a pressure sensor arranged between the connecting block and the connecting bracket along the front-back push-pull direction, and a connecting piece connecting the push-pull buffer mechanism and the pressure sensor; the other end of the push-pull buffer mechanism is fixed on the connecting block, and the other end of the pressure sensor is fixed on the connecting bracket.

[0007] As a preferred solution, the lifting buffer mechanism includes a lubricating sleeve, a lifting guide rod, and a lifting spring sleeved outside the lifting guide rod; the lubricating sleeve is fixed in the first connecting hole of the connecting block; one end of the lifting guide rod is fixedly connected to the push-pull head, and the other end of the lifting guide rod is movably inserted into the lubricating sleeve; one end of the lifting spring is fixedly connected to the push-pull head, and the other end of the lifting spring is movably inserted into the first connecting hole. The lifting spring is clamped with the push-pull head. On the one hand, it can prevent the push-pull head from moving downward under the influence of gravity in the non-measuring state. On the other hand, it can buffer the lifting movement of the push-pull head in the measuring state; therefore, the lifting buffer mechanism can buffer the lifting movement of the push-pull force test mechanism and ensure the smoothness of the measurement curve.

[0008] As a preferred solution, the push-pull buffer mechanism includes a connecting guide rod, a connecting guide sleeve including a connecting cylindrical part and a connecting fixing part, and two buffer springs respectively located on both sides of the connecting guide sleeve; the connecting guide rod passes through the connecting guide sleeve and the two buffer springs in the middle, one end of the connecting guide rod is movably inserted into the second connecting hole of the connecting block, and the other end of the connecting guide rod is fastened with a nut. The two buffer springs are respectively located on both sides of the connecting guide sleeve and buffer the front-back movement of the connecting guide sleeve on the connecting guide rod. Since the push-pull buffer mechanism is fixedly connected to the pressure sensor, the push-pull buffer mechanism also buffers the front-back movement of the pressure sensor. Therefore, the push-pull buffer mechanism can buffer the front-back push-pull movement of the push-pull force test mechanism and ensure the smoothness of the measurement curve.

[0009] As a preferred solution, the push-pull force testing mechanism further includes two push-pull guide rods symmetrically arranged on both sides of the push-pull buffer mechanism, and two push-pull guide sleeves each including a push-pull cylindrical portion and a push-pull fixing portion; the two push-pull cylindrical portions are respectively inserted into two third connection holes of the connection block, and the two push-pull fixing portions are fixedly connected to the connection block; one ends of the two push-pull guide rods are respectively movably inserted into the two push-pull cylindrical portions, and the other ends of the two push-pull guide rods are respectively fixedly connected to the connection bracket. The two symmetrically arranged push-pull guide rods play a guiding and supporting role in the forward and backward push-pull movement of the push-pull force testing mechanism to ensure the smoothness of the measurement curve.

[0010] As a preferred solution, the connecting piece includes a first connecting portion and a second connecting portion; a through hole is provided in the middle of the first connecting portion, and a threaded hole is provided at the edge; the connecting cylindrical portion is inserted into the through hole, and the connecting fixing portion is threadedly connected to the threaded hole; an installation hole for fixedly connecting with the pressure sensor is provided in the middle of the second connecting portion. One end of the connecting piece is fixedly connected to the connecting guide sleeve of the push-pull buffer mechanism, and the other end of the connecting piece is fixedly connected to the pressure sensor, so that the connecting guide sleeve and the pressure sensor can move simultaneously.

[0011] As a preferred solution, the connection block is provided with a vertical groove for the pressure sensor to move in the vertical direction, and a horizontal groove for the lifting guide rod to move in the horizontal direction. The design of the vertical groove and the horizontal groove avoids movement interference, has a simple structure and a reasonable design.

[0012] As a preferred solution, the connection bracket includes a first bracket and a second bracket perpendicular to the first bracket. The first bracket is threadedly connected to the pressure sensor and the push-pull guide rod respectively, and the second bracket is threadedly connected to the second connecting piece. The connection bracket has a simple structure and low cost.

[0013] As a preferred solution, the first connecting piece includes a first connecting plate and a second connecting plate perpendicular to the first connecting plate. The first connecting plate is threadedly connected to the front and rear push-pull cylinders, and the second connecting plate is threadedly connected to the vertical lifting cylinder. The first connecting piece has a simple structure and low cost.

[0014] As a preferred solution, the second connecting piece includes a third connecting plate and a fourth connecting plate perpendicular to the third connecting plate. The third connecting plate is threadedly connected to the vertical lifting cylinder, and the fourth connecting plate is threadedly connected to the second bracket. The second connecting piece has a simple structure and low cost.

[0015] The advantages of the present invention are as follows: The vertical lifting cylinder of the sunshade pull and push force testing device controls the vertical lifting movement of the pull and push force testing mechanism, and the front and rear push and pull cylinders control the front and rear movement of the pull and push force testing mechanism along the moving direction of the sunshade handle. The testing device includes both a lifting buffer mechanism and a push and pull buffer mechanism, which can not only buffer the lifting movement of the pull and push force testing mechanism, but also buffer the front and rear push and pull movement of the pull and push force testing mechanism. In addition, when the pull and push force testing mechanism is impacted by a strong horizontal force, the push and pull buffer mechanism can also weaken the impact force and protect the pressure sensor to ensure the smoothness of the measurement curve.

[0016] The push and pull force transmitted from the sunshade handle to the push and pull head is transmitted to the connecting block through the lifting buffer mechanism, and then to the push and pull buffer mechanism. The push and pull buffer mechanism transmits the force to the pressure sensor through the connecting piece, avoiding the direct action of the push and pull force of the connecting block on the pressure sensor. The push and pull force undergoes multiple layers of buffering, thus ensuring the smoothness of the measurement curve and achieving the purpose of high repeatability and reproducibility of the test value and accurate test results.

[0037] Define the front - rear movement direction of the sunroof as the front - rear direction, and the direction perpendicular to the sunroof as the vertical direction.

[0038] As Figure 1 As shown, a push - pull force test device for a sunshade curtain of an automotive sunroof according to the present invention includes a front - rear push - pull cylinder 2, a vertical lifting cylinder 3, a push - pull force test mechanism 6, a first connecting member 4 fixedly connecting the front - rear push - pull cylinder 2 and the vertical lifting cylinder 3, and a second connecting member 5 fixedly connecting the vertical lifting cylinder 3 and the push - pull force test mechanism 6; the first connecting member 4 and the second connecting member 5 are respectively arranged on both sides of the vertical lifting cylinder 3.

In this embodiment, an electric cylinder is selected, which can be compatible with different models of products on the same device to achieve flexible production.

[0042] As Figure 2 As shown, the push - pull force test mechanism 6 includes a push - pull head 61 whose upper part abuts against the sunshade curtain handle 1, a connecting block 62 arranged below the push - pull head 61, a lifting buffer mechanism 63 connecting the push - pull head 61 and the connecting block 62, a connecting bracket 64 arranged on the side of the connecting block 62, a push - pull buffer mechanism 65 and a pressure sensor 66 arranged between the connecting block 62 and the connecting bracket 64 along the front - rear push - pull direction, a connecting piece 67 connecting the push - pull buffer mechanism 65 and the pressure sensor 66, two push - pull guide sleeves 68 and two push - pull guide rods 69.

[0043] The push-pull head 61 is convex, and there are two mounting holes for the two push-pull guide rods 69 on both sides respectively. The push-pull head 61 is made of nylon material. When the push-pull resistance is too large, the push-pull head 61 will automatically disengage, ensuring that the sunshade handle 1 will not be scratched or damaged.

[0044] The connecting block 62 is shaped like Figure 5 shown. There are two first connecting holes 621 for mounting the push-pull guide rods 69 at the upper end, a second connecting hole 622 for mounting the connecting guide rod 651 in the middle of the side, two third connecting holes 623 for mounting the push-pull guide sleeves 68 on both sides of the side, a vertical groove 624 for the pressure sensor 66 to move in the vertical direction, and a horizontal groove 625 for the lifting guide rod 632 to move in the horizontal direction on the connecting block 62.

[0046] The connecting bracket 64 includes a first bracket 641 and a second bracket 642 perpendicular to the first bracket 641. The first bracket 641 is respectively threadedly connected to the pressure sensor 66 and the push-pull guide rod 69, and the second bracket 642 is threadedly connected to the second connecting member 5.

[0047] The push-pull guide sleeve 68 includes a push-pull cylindrical portion 681 and a push-pull fixing portion 682, and a ball bearing is contained in the push-pull cylindrical portion 681. The two push-pull cylindrical portions 681 are respectively inserted into the two third connecting holes 623 of the connecting block 62, and the two push-pull fixing portions 682 are fixedly connected to the connecting block 62. The two push-pull guide rods 69 are symmetrically arranged on both sides of the push-pull buffer mechanism 65. One end of the two push-pull guide rods 69 is respectively movably inserted into the two push-pull cylindrical portions 681, and the other end of the two push-pull guide rods 69 is respectively fixedly connected to the connecting bracket 64.

[0048] As Figure 3As shown, the push-pull buffer mechanism 65 includes a connecting guide rod 651, a connecting guide sleeve 652 including a connecting cylindrical portion 6521 and a connecting fixing portion 6522, and two buffer springs 654 respectively located on both sides of the connecting guide sleeve 652. The connecting cylindrical portion 6521 contains a ball bearing. The connecting guide rod 651 passes through the connecting guide sleeve 652 and the two buffer springs 654 in the middle. One end of the connecting guide rod 651 is movably inserted into the second connecting hole 622 of the connecting block 62, and the other end of the connecting guide rod 651 is fastened with a nut 655. One end of the push-pull buffer mechanism 65 is movably inserted into the second connecting hole 622 through the connecting guide rod 651. The middle part of the push-pull buffer mechanism 65 is fixedly connected to the connecting piece 67 by screw threads through the connecting fixing portion 6522. A movable gap is reserved between the other end of the push-pull buffer mechanism 65 and the connecting bracket 64.

[0049] One end of the pressure sensor 66 is threadedly connected to the mounting hole 6721, and the other end of the pressure sensor 66 is fixed on the connecting bracket 64.

[0050] As Figure 4 As shown, the connecting piece 67 includes a first connecting portion 671 and a second connecting portion 672. A through hole 6711 is provided in the middle of the first connecting portion 671, and a threaded hole 6712 is provided at the edge. The connecting cylindrical portion 6521 is inserted into the through hole 6711, and the connecting fixing portion 6522 is threadedly connected to the threaded hole 6712. An installation hole 6721 for fixedly connecting to the pressure sensor 66 is provided in the middle of the second connecting portion 672.

[0051] As Figure 6 As shown, the planar force diagram of the push-pull force testing mechanism. At the start of the test, a thrust F1 is transmitted from the sunshade curtain handle 1 to the push-pull head 61. After being buffered by the lifting buffer mechanism 63, the thrust F1 is transmitted to the connecting block 62 and becomes a thrust F2. The connecting block 62 transmits the thrust F2 to the push-pull buffer mechanism 65. After being buffered by the push-pull buffer mechanism 65, the thrust F2 becomes a thrust F3. The push-pull buffer mechanism 65 transmits the thrust F3 to the pressure sensor 66 through the connecting piece 67, avoiding the direct thrust action of the connecting block 62 on the pressure sensor 66. The thrust is buffered layer by layer, thereby ensuring the smoothness of the measurement curve, so as to achieve the purpose of high repeatability and reproducibility of the test value and accurate test results.

[0052] The force analysis of the pull force received by the push-pull force testing mechanism is the same and will not be elaborated here.

[0053] Test process:

[0054] Before the test is started, the push-pull force testing mechanism 6 is at the lowermost end of the vertical lifting cylinder 3 and the foremost end of the front-back push-pull cylinder 2.

[0055] When the test starts, the vertical lifting cylinder 3 lifts the push-pull force test mechanism 6 upward, so that the push-pull head 61 abuts against the sunshade curtain handle 1; the front and rear push-pull cylinders 2 drive the push-pull force test mechanism 6 to move back and forth, pushing and pulling the sunshade curtain handle 1 back and forth. The sunshade curtain handle 1 exerts a pushing force or a pulling force on the push-pull head 61. The pressure sensor 66 collects the data of the pushing force or the pulling force and converts it into an actual value through the PLC, which is stored in the database of the upper computer for subsequent traceability and query, and can also be saved in the form of a curve.

[0056] After the test is completed, the vertical lifting cylinder 3 moves the push-pull force test mechanism 6 to the lowest end, and at the same time, the front and rear push-pull cylinders 2 drive the push-pull force test mechanism 6 to move to the most front end.

[0057] The sunshade curtain push-pull force test device has strong versatility and can be applied to various devices for testing the push-pull force of skylight sunshade curtains.

[0058] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
