[0029] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0030] like Figure 1 As shown, the car includes: an engine cover 100 and a fender 200, and the intersection point of the engine cover 100 and the fender 200 when the engine cover 100 is opened or closed is the interference part O. Figure 1 The position of the interference portion O is shown. When the hood 100 is opened, the rear end of the hood 100 sinks. The amount of this sinking affects the gap between the hood 100 and the fender 200. If the gap is large, the user can easily see the internal components through the gap, affecting the aesthetics of the vehicle. If the gap is small, the hood 100 can easily interfere with the fender 200 during opening, causing scratches or wear, which also affects the aesthetics of the vehicle's exterior.

[0031] The size of the gap between the hood 100 and the fender 200 needs to be adjusted by measuring the data of the nodding amount of the hinge four-bar linkage 300 .

[0032] The following will refer to Figures 1-4 The tool 400 for measuring the hinge four-bar linkage of the present invention will be described in detail in conjunction with the embodiments.

[0033] like Figure 3 and Figure 4 As shown, a tool 400 for measuring a hinge four-bar linkage according to an embodiment of the present invention includes: a mounting platform 40 , a supporting component 50 , a nodding measurement device 60 and a connecting arm 70 .

[0034] Two support members 50 are spaced apart and arranged on the mounting platform 40. The support members 50 include a base member 52 and an oblique support arm 51. The base member 52 is arranged on the mounting platform 40, and the oblique support arm 51 is arranged on the base member 52 and partially extends away from the mounting platform 40. This ensures the installation and fixation of the oblique support arm 51 and the base member 52, ensuring the stability of the structure.

[0035] The nodding measurement device 60 is set on the supporting inclined arm 51, and the nodding measurement device 60 includes: a circular dial 61 with a telescopic part 611 and a force rod 62 with a pressure block 621, the pressure block 621 is set at one end of the force rod 62 close to the supporting inclined arm 51, and the telescopic part 611 is set at the top of the circular dial 61 and corresponds to the pressure block 621.

[0036] The connecting arm 70 is connected to the end of the force rod 62 away from the telescopic member 611 and defines an opening area 53 with the base component 52. The opening area 53 is used to install the hinge four-bar linkage 300. Figure 2The hinged four-bar linkage 300 includes a first arm 30, a second arm 31, a third arm 32 and a fixed connecting frame 33 (as shown in FIG. Figure 3 (shown) The fixed connecting frame 33 is arranged on the base component 52 and is fixedly connected to the base component 52.

[0037] like Figure 2 As shown, a first hinge connection 34 is formed between one end of the first arm 30 and one end of the second arm 31, and a second hinge connection 35 is formed between one end of the first arm 30 and one end of the third arm 32 (as shown in FIG. Figure 3 and Figure 4 (As shown) the first arm 30 is mounted on the upper end of the opening area 53 and fixedly connected to the connecting arm 70, the other end of the second arm 31 is mounted on the side of the fixed connecting frame 33 at the lower end of the opening area 53 and connected to the fixed connecting frame 33, and the other end of the third arm 32 is mounted on the side of the fixed connecting frame 33 away from the connection between the second arm 31 and the fixed connecting frame 33 and connected to the fixed connecting frame 33.

[0038] The base component 52 is fixedly connected to the mounting platform 40, the support arm 51 is fixedly connected to the base component 52, and the nodding measurement device 60 is fixedly connected to the end of the support arm 51 away from the mounting platform 40, thereby achieving fixation. When the force application handle 81 is lifted upward, the force application handle 81 drives the connecting arm 70, and the connecting arm 70 drives the first arm 30 and the first arm 30 to rotate counterclockwise around the first hinge connection 34 and the second hinge connection 35 by a predetermined angle. The nodding measurement device 60 records the value of the nodding amount of the hinged four-bar linkage 300. Through multiple measurements, the measured data are compared before and after to see if there is a large data gap. If there is a large data gap, the hinged four-bar linkage 300 needs to be optimized, and the optimized hinged four-bar linkage 300 needs to be re-measured until it meets the standard.

[0039] It should be noted that when the force handle 81 is lifted, the pressure block 621 presses down the telescopic part 611, and the circular dial 61 measures the nodding amount of the hinged four-bar linkage 300 through the movement of the telescopic part 611. Before measuring the hinged four-bar linkage 300, the circular dial 61 needs to be set to zero to ensure the accuracy of the data measurement.

[0040] Furthermore, the support oblique arm 51 is disposed on the base member 52 and partially extends in a direction away from the mounting platform 40. In other words, one end of the support oblique arm 51 is fixedly connected to the mounting platform 40, while the other end extends outward, that is, in a direction away from the mounting platform 40 or away from the base member 52. This design is intended to increase the range of motion of the hinged four-bar linkage 300 during operation, and to prevent interference with the support oblique arm 51 during operation, which could affect measurement accuracy. Therefore, the other end of the support oblique arm 51 needs to be extended outward.

[0041] According to the tool 400 for measuring the hinged four-bar linkage according to the embodiment of the present invention, the nodding amount of the hinged four-bar linkage 300 is measured by setting the detection tool, and the gap between the engine cover 100 and the fender 200 is adjusted according to the value of the nodding amount. By adjusting the gap, the aesthetics of the exterior of the entire vehicle is achieved, and interference between the engine cover 100 and the fender 200 or a large gap affecting the appearance of the exterior of the entire vehicle is avoided.

[0042] like Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the connecting arm 70 includes: a first connecting arm 701 and a second connecting arm 702, one end of the first connecting arm 701 and one end of the second connecting arm 702 are integrally formed into an L shape, or, one end of the first connecting arm 701 and one end of the second connecting arm 702 are welded to form an L shape, wherein the first connecting arm 701 extends along the direction away from the hinge of the first arm 30 and is connected in parallel with the first arm 30, and the second connecting arm 702 is perpendicular to the first connecting arm 701 and extends in a direction away from the first connecting arm 701.

[0043] In other words, the first connecting arm 701 is provided to enable assembly with the first arm 30 of the hinged four-bar linkage 300, and the second connecting arm 702 is provided to securely mount the nodding measurement device 60. Thus, the first connecting arm 701 and the second connecting arm 702 are used to enable the nodding measurement device 60 to measure the nodding amount of the hinged four-bar linkage 300.

[0044] In some embodiments, at least two first positioning holes 7011 are defined in the first connecting arm 701, and three second positioning holes are defined in the second connecting arm 702. Positioning screws are used to securely connect the first connecting arm 701 to the first arm 30, and the second connecting arm 702 to the force-applying rod 62 in the nodding measurement device 60. This further secures the nodding measurement device 60, ensuring overall structural stability during measurement and the accuracy of the measured data.

[0045] like Figure 3 and Figure 4 As shown, in some embodiments, the tool 400 for measuring a hinged four-bar linkage further includes a connecting block 80, which is disposed on the second connecting arm 702 and parallel to the second connecting arm 702. The connecting block 80 defines three third positioning holes 801, with the three second positioning holes corresponding coaxially to the three third positioning holes 801. The provision of the connecting block 80 ensures stability in the assembly of the connecting arm 70 and the force-applying rod 62, further enhancing stability of the nodding measurement device 60 and ensuring measurement accuracy.

[0046] like Figure 3 and Figure 4As shown in the drawings, in some embodiments, the force applying rod 62 is bent outwardly at a predetermined angle at one end away from the pressing block 621 to form a flange rod 622, which is connected with any one of the three third positioning holes 801. Among them, the force applying rod 62 is bent outwardly at a predetermined angle at one end away from the pressing block 621 to form a flange rod 622, which realizes the fixed connection with the second connecting arm 702.

[0047] As shown in the drawings, Figure 3 As shown in the drawings, according to one embodiment of the present application, the base component 52 comprises: four pads 521, a bottom plate 522 and a stepped seat 523, the four pads 521 are arranged at intervals on the mounting table 40, the bottom plate 522 is arranged on the four pads 521 and is fixedly connected with the four pads 521, and the stepped seat 523 is arranged on the bottom plate 522, wherein the stepped seat 523 defines an opening area 53 with the connecting arm 70 and the force applying rod 62. Thereby realizing the assembly and fixation of the hinge four-bar linkage mechanism 300, the structure design is simple, and the stability of the structure is ensured.

[0048] As shown in the drawings, Figure 3 and Figure 4 As shown in the drawings, in some embodiments, the side surface of the stepped seat 523 has an outwardly protruding step 5231, and the fixed connecting frame 33 is fixedly installed on the side surface away from the step. Specifically, the side surface of the stepped seat 523 has an outwardly protruding step 5231, and the fixed connecting frame 33 has an inwardly recessed avoiding area 331, which realizes the fixed assembly in cooperation with the protruding step 5231.

[0049] As shown in the drawings, Figure 3 and Figure 4 As shown in the drawings, according to one embodiment of the present application, the hinge four-bar linkage mechanism 300 further comprises: a hinge locking device 82, the side surface of the fixed connecting frame 33 is provided with an avoiding opening 332, and the hinge locking device 82 cooperates with the avoiding opening 332. Thereby realizing the fixation of the fixed connecting frame 33 and the stepped seat 523, ensuring the stability of the structure and the accuracy of the measurement.

[0050] As shown in the drawings, Figure 3 and Figure 4 As shown in the drawings, according to one embodiment of the present application, the tool 400 for measuring the hinge four-bar linkage mechanism further comprises: a force applying handle 81, which is connected with one end of the connecting arm away from the force applying rod 62. Thereby the design provides convenience for user operation, saves time and effort, and has high work efficiency.

[0051] In combination Figure 1 -As shown in FIG. 4, one specific embodiment of the tool 400 for measuring the hinge four-bar linkage mechanism according to the embodiment of the present application is provided.

[0052] The tool 400 for measuring the hinge four-bar linkage mechanism comprises: a mounting table 40, a supporting component 50, a nodding measuring device 60, a connecting arm 70 and a force applying handle 81.

[0053] The two support members 50 are spaced apart and arranged on the mounting platform 40. The nodding measurement device 60 is mounted on the support members 50, with two nodding measurement devices 60 corresponding to each of the two support members 50. A connecting arm 70 is connected to one end of the nodding measurement device 60, with two connecting arms 70 corresponding to each of the two nodding measurement devices 60. A force application handle 81 is connected to the end of the connecting arm 70 away from the nodding measurement device 60. The force application handle 81 can be formed by welding two connecting rods into a "human" shape.

[0054] The support component 50 includes a support arm 51 and a base component 52. The support arm 51 is mounted on the base component 52. A nodding measurement device 60 is mounted on the support arm 51. The nodding measurement device 60 and the connecting arm 70 are connected to the base component 52 to define an opening area 53 for mounting the hinged four-bar linkage 300.

[0055] With this design, when the force-applying handle 81 is lifted to a predetermined height, the force applied by the force-applying handle 81 to the connecting arm 70 is transmitted to the nodding measuring device 60, and the nodding measuring device 60 measures the nodding amount of the hinged four-bar linkage 300 and records the measured value. In order to ensure the accuracy of the measurement, multiple measurements are required, and the multiple sets of measured data are compared before and after. The data before and after are compared to determine whether there is a large difference in the data. If the data differs greatly, the hinged four-bar linkage 300 needs to be adjusted or optimized and measured again until it meets the standard. If there is no abnormality in the measured data, the gap between the fender 200 and the hood 100 is adjusted according to the data without abnormality. On the one hand, the gap is avoided from being too large, which affects the aesthetics of the exterior of the entire vehicle. On the other hand, interference between the hood 100 and the fender 200 is avoided, such as scratches or wear, which also affects the appearance of the vehicle.

[0056] In addition, if the vehicle is mass-produced, before production, only the nodding quantity needs to be output, which can effectively support the normal operation of the site and improve work efficiency.

[0057] It should be noted that the hinged four-bar linkage 300 is mainly used to measure the amount of sinking of the rear end of the hood 100 during the opening process of the hood 100. The amount of sinking of the rear end of the hood 100 is determined by measuring the nodding amount of the hinged four-bar linkage 300, which is suitable for adjusting the gap spacing between the hood 100 and the fender 200.

[0058] The base component 52 includes four pads 521 , a bottom plate 522 and a stepped seat 523 . The four pads 521 are disposed on the mounting platform 40 , the bottom plate 522 is disposed on the four pads 521 , and the stepped seat 523 is mounted on the bottom plate 522 .

[0059] The hinged four-bar linkage 300 includes a first arm 30, a second arm 31, a third arm 32, and a fixed connecting frame 33. A first hinged connection 34 is formed between one end of the first arm 30 and one end of the second arm 31, and a second hinged connection 35 is formed between one end of the first arm 30 and one end of the third arm 32. The other end of the first arm 30 is fixedly connected to the connecting arm 70, the other end of the second arm 31 is fixedly connected to a side of the fixed connecting frame 33, and the other end of the third arm 32 is fixedly connected to a side facing away from the fixed connecting frame 33. The fixed connecting frame 33 is fixedly connected to the stepped seat 523. This design secures the fixed connecting frame 33 to the stepped seat 523, completing the assembly of the hinged four-bar linkage. This ensures that when the connecting arm 70 drives the first arm 30 upward, the fixed connecting frame 33 remains stationary, improving the accuracy of the measurement data and enhancing the stability of the structure.

[0060] The nodding measurement device 60 includes a circular dial 61 with a telescopic member 611 and a force-applying rod 62 with a pressure block 621. When the force-applying handle 81 is lifted, the connecting arm 70 causes the first arm 30 to tilt upward to a predetermined angle. The pressure block 621 presses down on the telescopic member 611, and the circular dial 61 measures and displays the nodding value of the hinged four-bar linkage 300. This design enables more accurate measurement of the nodding value of the hinged four-bar linkage 300, allowing abnormalities in the hinged four-bar linkage 300 to be detected using the measurement data. This ensures the stability of the gap between the hood 100 and the fender 200 when adjusted based on the nodding value data of the hinged four-bar linkage 300.
