Description

Technical Field

[0001] This application relates to the field of automotive body door hinge strength detection technology, and particularly to an automotive body door hinge strength detection device. Background Art

[0002] The strength detection of automotive body door hinges is a key link in automotive R & D, production, and quality control. To ensure driving safety, guarantee the reliability of door functions, and extend the service life of doors, it is necessary to detect the strength of the hinges themselves before they are officially put into use in vehicles, so as to determine whether the hinges meet the process standards.

[0003] Currently, in the field of door hinge strength detection, common detection methods include static pressure testing and dynamic load simulation. Static pressure testing usually installs the hinge on a test platform through a fixed fixture and uses a hydraulic or pneumatic device to apply a unidirectional pressure to detect the load-bearing capacity of the hinge. Dynamic load simulation simulates the torque changes in actual use scenarios, for example, applying forces in different directions to the hinge through a rotating mechanism to evaluate its performance under complex working conditions. In addition, there is also a method of applying force to the hinge by manually operating a manual tool and observing its deformation. These methods are all aimed at detecting the strength characteristics of the hinge through different means.

[0004] However, the existing detection means have certain limitations. For example, static pressure testing can only detect the load in a single direction and cannot comprehensively reflect the performance of the hinge under multi-directional forces; although dynamic load simulation can partially solve the problem of multi-directional detection, its structure is complex, difficult to adjust, and it is difficult to accurately align with the rotation axis of the hinge, resulting in inaccurate detection results. Summary of the Invention

[0005] In order to further improve the accuracy of the detection structure for hinges, this application provides an automotive body door hinge strength detection device.

[0006] The automotive body door hinge strength detection device provided by this application adopts the following technical solutions: An automobile body door hinge strength detection device includes a detection table, on which a fixed seat is installed. One side of the hinge is installed on the fixed seat. A lateral pressure application structure and a vertical pressure application structure are installed on the detection table. The lateral pressure application structure includes a side pressure seat, a rotating member, and a first pressure rod. The pressure measuring seat is installed on the detection table through an adjustment assembly. The position of the pressure measuring seat is adjusted through the adjustment assembly to correspond to the rotation axis of the hinge. The rotating member is installed on the pressure measuring seat, and the first pressure rod is installed on the rotating member. The rotating member drives the first pressure rod to rotate to apply a lateral pressure to the hinge for horizontal load measurement and longitudinal load measurement. The vertical pressure application structure is installed on the detection table and is installed corresponding to the extreme position of the hinge rotation, and is used to apply a vertical pressure to the hinge for vertical load measurement.

[0007] By adopting the above technical solution, it is possible to comprehensively detect the strength of the automobile body door hinge. The fixed seat on the detection table is used to stably install the hinge to ensure the fixed position of the hinge during the detection process. The lateral pressure application structure adjusts the position of the side pressure seat through the adjustment assembly to match the hinge rotation axis. The rotating member drives the first pressure rod to rotate, thereby applying an accurately controllable lateral pressure to the hinge to complete the application and detection of horizontal and longitudinal loads. The vertical pressure application structure is installed according to the hinge rotation position and can apply a vertical pressure to the hinge to complete the detection of the vertical load. At the same time, it can cooperate with the lateral pressure application structure to perform the detection synchronously, thus simulating the real force-bearing scenario of the car door when actually opening the door. This solution effectively improves the comprehensiveness and accuracy of the detection, ensures that the strength performance of the hinge under various force conditions is fully verified, and provides a guarantee for the safety and reliability of the automobile.

The two driving gears are symmetrically meshed on both sides of the auxiliary gear respectively, which further ensures the uniform distribution of the driving force, enhances the accuracy and reliability when the first pressure rod applies lateral pressure, and improves the accuracy of the hinge strength detection.

[0014] In a specific feasible implementation, the first pressure rod includes a first rod body, a second rod body and a third rod body.

The side pressure seat is installed on the testing table 1 through an adjustment assembly 5, and the adjustment assembly 5 is used to adjust the position of the side pressure seat so that it corresponds to the rotation axis of the hinge. The rotating member is installed on the side pressure seat and is used to drive the pressure rod to rotate, so as to apply a lateral pressure to the hinge and realize the detections of the lateral load and the longitudinal load. The vertical pressure application structure 4 is installed on the testing table 1 and is arranged corresponding to the rotation position of the hinge, and is used to apply a vertical pressure to the hinge to complete the detection of the vertical load.

[0035] As Figures 3 - 4 shown, specifically, the adjustment assembly 5 includes a motor, a lead screw and an adjustment block 53. The motor is installed in an adjustment groove on the testing table 1, and the adjustment groove is arranged along the length direction of the hinge. The lead screw is rotatably connected in the adjustment groove and is fixedly connected to the output shaft of the motor. The adjustment block 53 is installed at the bottom of the pressure measuring seat 31, is slidably connected in the adjustment groove, and is drivingly connected to the lead screw. By driving the lead screw to rotate through the motor, the adjustment block 53 drives the side pressure seat to move along the adjustment groove, so as to accurately align with the rotation axis of the hinge.

[0036] Specifically, the rotating member includes a rotating base 321 and a motor. A cavity is formed in the pressure measuring base 31. A support rod 323 is installed at the center of the lower end of the rotating base 321. The support rod 323 penetrates through the side wall of the pressure measuring base 31 and extends into the cavity. A toothed ring is installed at one end of the support rod 323 extending into the cavity. The motor is installed on the side pressure base, and the output shaft extends into the cavity and is equipped with a driving gear 324. The driving gear 324 meshes with the toothed ring. By driving the rotation of the rotating base 321 with the motor, the pressure rod is driven to apply a lateral pressure to the hinge.

[0037] The rotating base 321 realizes stable rotation through the cooperation of the support rod 323 and the auxiliary toothed ring 325. The rotating motor 322 drives the gear 324 to mesh with the auxiliary toothed ring 325, which can accurately control the rotation angle and force of the rotating base 321, thereby driving the first pressure rod 33 to accurately apply a lateral pressure. This solution improves the controllability and accuracy of the lateral pressure application, ensures the reliability of the lateral load measurement and longitudinal load measurement of the hinge, and further improves the detection accuracy and efficiency.

[0038] To improve the stability of the rotating base 321, two sets of motors are arranged symmetrically on both sides of the support rod 323. The two sets of motors respectively drive the corresponding driving gears 324, and the two driving gears 324 are symmetrically meshed on both sides of the toothed ring, so as to realize bilateral synchronous drive and ensure the stable operation of the rotating base 321.

[0039] Specifically, the pressure rod includes a first rod body 331, a second rod body 332 and a third rod body 333. The first rod body 331 is installed on the rotating base 321. A chute is formed on the rotating base 321. The first rod body 331 is slidably connected in the chute. The first rod body 331 is slid by the motor and the lead screw to adjust the position of the pressure rod. The second rod body 332 is perpendicular to the first rod body 331 and perpendicular to the hinge. The third rod body 333 is perpendicular to the second rod body 332. A pressure application cylinder is installed on the third rod body 333, and a pressure application block is installed on the piston rod of the pressure application cylinder. The piston rod of the pressure application cylinder is perpendicular to the hinge. By the telescopic movement of the piston rod of the pressure application cylinder, the pressure application block is pushed to contact the hinge to realize the accurate application of lateral pressure.

[0040] The combined design of the first rod body 331, the second rod body 332 and the third rod body 333 can accurately position the position of the lateral pressure application cylinder, ensure that the pressure application direction is perpendicular to the hinge, thereby improving the accuracy of the lateral pressure application. The lateral pressure application block 335 on the piston rod of the lateral pressure application cylinder further ensures the stable transmission of the pressure, effectively improving the reliability of the lateral load measurement of the hinge and the accuracy of the test results.

[0041] Specifically, the vertical pressure applying structure 4 includes a support frame 41, a transverse moving member 42, a longitudinal moving member 43, and a vertical pressure applying member 44. The support frame 41 is installed on the inspection table 1. The transverse moving member 42 is installed at the upper end of the support frame 41. The longitudinal moving member 43 is installed on the transverse moving member 42. The vertical pressure applying member 44 is installed on the longitudinal moving member 43. Through the cooperation of the transverse moving member 42 and the longitudinal moving member 43, the vertical pressure applying member 44 is driven to change its position as the hinge rotates, so as to accurately align different positions of the hinge to apply vertical pressure.

[0042] The vertical pressure applying mechanism can flexibly adjust the position of the vertical pressure applying member 44 according to the rotation position of the hinge. Specifically, the support frame 41 provides a stable installation foundation for the entire vertical pressure applying mechanism. The combined use of the transverse moving member 42 and the longitudinal moving member 43 realizes the precise displacement of the vertical pressure applying member 44 in space, so as to ensure that the vertical pressure applying member 44 can accurately follow the rotation limit position of the hinge for adjustment. This design effectively improves the adaptability and accuracy of the detection device, makes the process of applying vertical pressure to the hinge more reliable, and further improves the precision and efficiency of the vertical load measurement.

[0043] Specifically, the transverse moving member 42 includes a horizontal motor, a horizontal lead screw, a horizontal slide rail, and a moving seat. The horizontal slide rail is installed on the support frame 41. The horizontal motor is installed on the horizontal slide rail. The horizontal lead screw is arranged along the length direction of the horizontal slide rail and is fixedly connected to the output shaft of the horizontal motor. The moving seat is slidably connected to the horizontal slide rail and is drivingly connected to the horizontal lead screw. By driving the horizontal lead screw to rotate with the horizontal motor, the moving seat is driven to move along the horizontal slide rail to achieve the adjustment of the transverse position.

[0044] The structure of the longitudinal moving member 43 is the same as that of the transverse moving member 42, but its moving direction is perpendicular to the moving direction of the transverse moving member 42. Through the cooperation of the horizontal moving member and the longitudinal moving member 43, the precise positioning of the vertical pressure applying member 44 in the plane is realized.

[0045] Specifically, the vertical pressure applying member 44 includes a pressure applying cylinder and a vertical pressure applying block. The pressure applying cylinder is installed on the moving seat. The vertical pressure testing block is installed on the piston rod of the pressure applying cylinder. By the telescopic movement of the piston rod of the pressure applying cylinder, the vertical pressure applying block is driven to contact the hinge to achieve the application of vertical pressure.

[0046] The implementation principle of an automobile body door hinge strength detection device according to an embodiment of the present application is as follows: Through the synergistic effect of the lateral pressure application structure 3 and the vertical pressure application structure 4, precise pressure application detection of the hinge in multiple directions, including horizontal, longitudinal, and vertical directions, is achieved. The introduction of the adjustment component 5 ensures that the lateral pressure application structure 3 can accurately align with the rotation axis of the hinge, improving the detection accuracy. The design of dual-motor drive enhances the stability of the rotating seat 321, avoiding deviations caused by unilateral force. The cooperation of the lateral moving member 42 and the longitudinal moving member 43 enables flexible positioning of the vertical pressure application member 44 within the plane, further improving the flexibility and accuracy of the detection. The overall solution simplifies the structural design, reduces the operation difficulty, and significantly improves the detection efficiency while ensuring the detection accuracy.
