Detailed Implementation

[0025] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0026] The following describes, with reference to the accompanying drawings, a method, apparatus, electronic device, and medium for testing the opening force of a concealed car door handle according to embodiments of this application. First, the method for testing the opening force of a concealed car door handle according to embodiments of this application will be described with reference to the accompanying drawings.

[0027] Figure 1 This is a flowchart of a method for testing the opening force of a concealed car door handle according to an embodiment of this application.

[0028] like Figure 1 As shown, the method for testing the opening force of a concealed car door handle includes the following steps: In step S101, at least one test condition is determined for the concealed door handle to be tested.

[0029] Specifically, this application embodiment involves the installation and pretreatment of a concealed door handle: the concealed door handle is rigidly fixed to a test bench according to the actual vehicle posture, and the door lock body, controller, and emergency pull cable are connected in sequence. A simulated vehicle power supply is then connected, and the temperature is set to (23±2)°C and the humidity to (50±5)%RH. The handle is then left to stand for 30 minutes to achieve stable operation. Further, the concealed door handle's reference parameters are calibrated: the positions of the door handle's closing surface, pop-out surface, and force application reference point are measured. For push-button door handles, the center area is measured at 50cm. 2 The effective pressing surface is determined, with the standard force application point 120mm from the pivot point for the pull-out type. The calibrated force sensor accuracy is ≤0.1mm, and the loading rate is set to 5mm / min~50mm / min and continuously adjustable. The device zero position, as well as the closed position, full extension stroke, and effective extension stroke parameters of the emergency pull cord are collected synchronously. After parameter calibration, an opening force test is conducted. The relative standard deviation (RSD) of the data repeatability in this embodiment is ≤3%, ensuring the reliability and repeatability of the test results. The test range comprehensively covers all operation modes: electric pop-out, manual opening, and emergency mechanical opening, achieving full-dimensional verification of the mechanical performance of the door handle under different opening methods. Thus, the concealed door handle to be tested is obtained.

[0030] Furthermore, embodiments of this application determine at least one test condition for the concealed door handle to be tested.

[0031] In step S102, based on at least one test condition, the opening force test is performed on the concealed door handle to be tested to obtain the opening force test result. The opening force test result includes at least one of the following: electric pop-out force test result, manual opening force test result, emergency mechanical opening force test result, and extreme condition test result.

[0032] Specifically, in this embodiment of the application, based on at least one test condition determined in step S101, the opening force performance test is carried out on the concealed door handle to be tested after installation and pretreatment, and the corresponding opening force test results are obtained. The opening force test is at least one of electric pop-out force test, manual opening force test, emergency mechanical opening force test and extreme condition test.

[0033] Furthermore, in some embodiments, based on at least one test condition, an opening force test is performed on the concealed door handle to be tested to obtain an opening force test result, including: performing an electric ejection force test on the concealed door handle to be tested to obtain an electric ejection force test result; and / or, performing a manual opening force test on the concealed door handle to be tested to obtain a manual opening force test result; and / or, performing an emergency mechanical opening force test on the concealed door handle to be tested to obtain an emergency mechanical opening force test result; and / or, performing an extreme condition test on the concealed door handle to be tested to obtain an extreme condition test result.

[0034] Optionally, in some embodiments, the electric pop-out force test of the concealed door handle to be tested to obtain the electric pop-out force test result includes: sending an unlocking command to the concealed door handle to be tested, and driving the door handle to pop out based on the unlocking command; applying a first load of reverse resistance to the pop-out surface of the door handle; collecting the force-displacement-time curve of the entire pop-out process of the door handle, and obtaining the electric pop-out force test result based on the force-displacement-time curve.

[0035] The pop-out surface refers to the effective working surface of the concealed door handle that extends outward during the electric pop-out action, and it is also the designated force-bearing surface on which the reverse resistance is applied during the test. The first load can be a load preset by the user, a load obtained through a finite number of experiments, or a load obtained through a finite number of computer simulations.

[0036] Specifically, the embodiment of the present application sends an unlocking instruction to the hidden door handle to be tested, drives the motor to drive the door handle to perform an ejection action, and simultaneously applies a constant reverse resistance of 5N to 20N to the ejection surface of the door handle through a resistor. The force-applying joint is a profilable contact surface made of Shore A60 silica gel, and adopts force / displacement double closed-loop loading. The embodiment of the present application synchronously collects the force-displacement-time curve of the entire ejection process of the door handle, and extracts core characteristic parameters including peak thrust, stable thrust and ejection time from the curve. The embodiment of the present application performs performance judgment according to preset standards. When the peak thrust is in the range of 20N to 200N, the ejection time is ≤1s, and there is no jamming during the ejection process, the electric ejection force test result is qualified; otherwise, it is unqualified.

[0037] Optionally, in some embodiments, performing a manual opening force test on the hidden door handle to be tested to obtain a manual opening force test result includes: placing the hidden door handle to be tested in an ejection in-place state; applying a second load at a preset loading rate along the preset direction of the hidden door handle until the door lock body is unlocked, and collecting the force value and stroke at the moment of unlocking; obtaining the manual opening force test result based on the force value and stroke at the moment of unlocking.

[0038] The ejection in-place state refers to a state where the hidden door handle is extended to the predetermined working position specified in the product design after the ejection action is completed by electric drive, and the structure remains stable without looseness or offset, which is the preset initial stable state for carrying out the manual opening force test. The preset direction may be a direction preset by a user, a direction obtained through a limited number of experiments, or a direction obtained through a limited number of computer simulations. The preset loading rate may be a loading rate preset by a user, a loading rate obtained through a limited number of experiments, or a loading rate obtained through a limited number of computer simulations. The second load may be a load preset by a user, a load obtained through a limited number of experiments, or a load obtained through a limited number of computer simulations.

[0039] Specifically, in the embodiment of the present application, the hidden door handle is placed in the ejection in-place state, force is applied perpendicularly along its opening direction, the loading rate is controlled to be 10mm / min, loading is continued until the door lock body is completely unlocked, and the opening force value and stroke at the moment of unlocking are synchronously recorded. Further, the qualification judgment of this test item is divided into two dimensions of mechanical performance and structural strength. The mechanical performance requires that the opening force of the outer handle is in the range of 40N to 65N, and the opening force of the inner handle is in the range of 20N to 40N. The structural strength requires that after a 500N acting force is applied to the door handle and held for 5s, the structure has no fracture, no falling off and can still be opened normally. If all the above conditions are met, the manual opening force test result is qualified; otherwise, it is unqualified.

[0040] Optionally, in some embodiments, performing an emergency mechanical opening force test on the hidden door handle to be tested to obtain an emergency mechanical opening force test result includes: cutting off the simulated vehicle power supply; applying a third load at a constant speed to the emergency cable and / or the mechanical pressing point until the vehicle door lock is unlocked, and collecting the unlocking force and unlocking time; obtaining the emergency mechanical opening force test result based on the unlocking force and the unlocking time.

[0041] Herein, the third load may be a pre-set load by the user, a load obtained through a limited number of experiments, or a load obtained through a limited number of computer simulations. The unlocking force refers to the instantaneous force at the moment of unlocking that enables the vehicle door lock to complete the unlocking action from the locked state. The unlocking time refers to the total time consumed from the start of applying force at a constant speed to the emergency cable and / or the mechanical pressing point after cutting off the simulated vehicle power supply, until the vehicle door lock fully completes the unlocking action.

[0042] Specifically, in the embodiments of the present application, the simulated vehicle power supply is first cut off to construct a failure simulation test environment after power failure or collision, force is applied at a constant speed to the emergency cable or the mechanical pressing point, and the unlocking force and unlocking time during the unlocking process are collected synchronously. Further, when the mechanical opening force ≤ 100N and the unlocking time ≤ 3s, the emergency mechanical opening force test result is qualified, otherwise, it is unqualified. Thereby, the operational feasibility and response timeliness of the emergency opening of the door handle in the failure scenario are verified.

[0043] Optionally, in some embodiments, performing a limit working condition test on the hidden door handle to be tested to obtain a limit working condition test result includes: placing the hidden door handle to be tested in a first temperature environment for a second duration, covering the surface with ice of a preset thickness, to obtain a pop-up and opening force result; applying a fifth load reverse force to the hidden door handle to be tested in the closed state, and maintaining it for a third duration, to obtain an accidental opening result; applying a sixth load to the vehicle door, to obtain an opening force attenuation result; performing a preset number of complete action cycles of electric pop-up, manual opening, and reset closing on the hidden door handle to be tested, to obtain a durability result; obtaining the limit working condition test result based on the pop-up and opening force result, the accidental opening result, the opening force attenuation result and the durability result.

[0044] The first temperature can be a user-preset temperature, a temperature obtained through a limited number of experiments, or a temperature obtained through a limited number of computer simulations. The second and third durations can be user-preset durations, durations obtained through a limited number of experiments, or durations obtained through a limited number of computer simulations. The preset thickness can be a user-preset thickness, a thickness obtained through a limited number of experiments, or a thickness obtained through a limited number of computer simulations. The preset number of tests can be a user-preset number of tests, a number obtained through a limited number of experiments, or a number obtained through a limited number of computer simulations. The fifth and sixth loads can be user-preset loads, loads obtained through a limited number of experiments, or loads obtained through a limited number of computer simulations.

[0045] Specifically, the opening force performance test under extreme conditions includes four categories: low-temperature icing, reverse anti-accidental opening, door negative pressure, and durability. In the low-temperature icing condition, the door handle under test is placed in a -35°C environment and kept at a constant temperature for 2 hours, then covered with 1mm~3mm of ice before testing the ejection force and opening force. In the reverse anti-accidental opening condition, a 50N reverse force is applied to the door handle while it is closed and maintained for 10 seconds to verify its anti-accidental opening performance. In the door negative pressure condition, a negative pressure of -250Pa~-500Pa is applied to the door to determine if there is any decrease in opening force. In the durability condition, the door handle undergoes a complete cycle of electric ejection-manual opening-reset closure 100,000 times, and the opening force fluctuation after the cycle is ≤±15% as the pass / fail criterion for the durability condition. The extreme condition test results are obtained based on the results of the four categories of tests: low-temperature icing, reverse anti-accidental opening, door negative pressure, and durability. If all four results are satisfactory, the extreme condition test result is considered satisfactory; otherwise, it is considered unsatisfactory.

[0046] In step S103, the test result of the concealed door handle to be tested is obtained based on at least one of the electric pop-out force test result, the manual opening force test result, the emergency mechanical opening force test result, and the extreme working condition test result.

[0047] In this embodiment, the force curve, stroke, time, and working condition parameters are integrated to generate a report, which yields the electric pop-out force test results, manual opening force test results, emergency mechanical opening force test results, and extreme working condition test results. If all four types of results are qualified, the test result of the hidden door handle under test is determined to be qualified; if any one of the four types of results is not met, the test result of the hidden door handle under test is determined to be unqualified. At the same time, the failure mode is recorded, which can be jamming, breakage, rebound failure, and unlocking delay, etc.

[0048] To facilitate further understanding by those skilled in the art of the concealed door handle opening force testing method in the embodiments of this application, the following is combined with... Figure 2 Further explanation is needed.
