Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle design and manufacturing, in particular to a frameless door glass adjusting method, equipment, device and storage medium. BACKGROUND

[0002] The frameless door of an automobile refers to a door form without a door frame on the upper and side parts of the door glass. The X, Y and Z directions of the glass of the frameless door need to be adjusted according to the system size requirements of the door and the vehicle body to ensure the functions of lifting, opening and closing and sealing of the frameless door system and the aesthetic requirements of the gap and surface difference. The gap and surface difference refers to the X or Z direction gap and the Y direction height difference of the frameless door glass and the surrounding environment parts (such as A, B and C pillar decorative plates and top sealing strips). Currently, the adjustment of the frameless door glass includes two modes: one is to use a tool to adjust on the door production line, and the other is to manually adjust after the vehicle is delivered.

[0003] For the mode of adjusting on the door production line by using a tool, each door needs to be checked by using a tool, and the adjustment is made after the deviation is obtained, which is a passive adjustment mode. Since each door needs to be checked to determine the adjustment amount of the door, it is a passive reaction to the actual state of the door. The adjustment time has an impact on the working hours of the production line. For the mode of manually adjusting after the vehicle is delivered, the non-compliant points of the door glass are checked after the vehicle is delivered, and then manual adjustment is performed, which is a remedial mode. There are problems of missing points and rework hours. SUMMARY

[0004] The present application provides a frameless door glass adjusting method, equipment, device and storage medium. By performing target setting, decomposition and verification operations of the frameless door system, the partial performance standard is avoided, the overall performance standard of the frameless door system is achieved, and the vehicle production efficiency is improved.

[0009] In combination with the first aspect, in an implementation, the function of the frameless door system is decomposed step by step to obtain the functional technical characteristics and key monitoring characteristics of each component of the frameless door system, specifically comprising:

[0010] The function of the frameless door system is decomposed step by step from the vehicle level to the system level and then to the component level;

[0024] In conjunction with the first aspect, in one implementation, the step of associating monitoring data with tooling automatic adjustment data to obtain a pre-adjustment amount, and adjusting the frameless door glass according to the pre-adjustment amount, specifically includes:

[0046] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0047] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0048] In the first aspect, the embodiments of this application provide a frameless car door glass adjustment method. By performing target setting, decomposition and verification operations of the frameless car door system, it can be ensured that the matching between the frameless car door glass and the surrounding environmental components meets the performance requirements of lifting, opening and closing, sealing and gap surface difference, avoiding partial performance compliance and achieving comprehensive compliance of the frameless car door system performance.

[0049] First, it should be noted that the frameless door glass adjustment method of this application is based on an adjustable frameless door system design. Specifically, the through-hole design for the glass and the window regulator allows the glass to adapt to the window regulator in both the X and Z directions with flexible tolerance; the holes in the glass and the bolts of the window regulator employ a clearance fit design with ±6mm in the X direction and ±6mm in the Z direction, enabling adjustment in both the X and Z directions.

[0050] The adjustable window regulator bolts allow for flexible tolerances and adaptability in the Y-axis for both the window regulator and the door glass on the frameless door system. The frameless door system utilizes a double-headed bolt structure to enable adjustment of the window regulator bolts. Adjustment amounts for the upper bolts are: unscrew 3.0±0.5mm, screw in 2.5±0.5mm; for the lower bolts, unscrew 7.5±0.5mm, screw in 5.5±0.5mm.

[0051] The frameless door system's X, Y, and Z-axis tolerances and performance are improved by adjusting the cross-section and compression force of the sealing strip. A tolerance of ±1.5mm is maintained for the interference between the sealing strip and the glass. Based on the sealing structure, the required tolerances around the glass are: ±1.5mm in the X direction, ±1.5mm in the Y direction, and ±1.5mm in the Z direction.

[0052] In one embodiment, reference is made to Figure 1 , Figure 1 This is a flowchart illustrating the frameless door glass adjustment method of this application. Figure 1 As shown, the frameless car door glass adjustment methods include:

[0053] S1: Decompose the functions of the frameless door system step by step to obtain the functional and technical characteristics and key monitoring characteristics of each component of the frameless door system;

[0054] Furthermore, in one embodiment, the functions of the frameless door system are decomposed step by step to obtain the functional technical characteristics and key monitoring characteristics of each component of the frameless door system, specifically including:

[0055] S101: The functions of the frameless door system are decomposed step by step from the vehicle level to the system level and then to the component level.

[0056] S102: Based on the decomposition results, obtain the functional and technical characteristics and key monitoring characteristics of each component of the frameless door system. Functional and technical characteristics are the performance parameters or technical indicators of the components that affect the implementation of the frameless door system's functions; key monitoring characteristics are the measurable and quantifiable technical or process parameters that affect the functional and technical characteristics.

[0057] The frameless door system's functions include sealing, aesthetics, door opening and closing, and window operation. Vehicle-level functional characteristics include sealing force, sealing gap, clearance, surface difference, door closing force, and window operation time. Vehicle-level key monitoring characteristics include sealing stop gap, glass perimeter gap, surface difference, door closing speed, window operation stroke, and window operation speed. System-level key monitoring characteristics include the frameless door system's door posture, including upper and lower hinge axis deviation, lock and latch engagement accuracy, and door glass adjustment tooling accuracy. Component-level key monitoring characteristics include the compressive load of the sealing strip, hinge positioning dimensions, upper and lower stop points of the window regulator, glass edge dimensions, side panel stop dimensions, front and rear door glass stop dimensions, and A / B / C pillar trim panel positioning dimensions.

[0058] S2: Based on the decomposition results, key monitoring characteristics of the frameless door system manufacturing process are monitored in real time.

[0059] Furthermore, in one embodiment, based on the decomposition results, key monitoring characteristics during the manufacturing process of the frameless door system are monitored in real time, specifically including:

[0060] S201: Based on the key monitoring characteristics obtained by decomposing the frameless door system step by step, the key monitoring characteristics of the frameless door system in the production process are monitored in real time; the key monitoring characteristics of the frameless door system involve the entire production process, from the purchased parts from the supplier to the stamping workshop, welding workshop and final assembly workshop of the vehicle manufacturing plant.

[0061] S202: Input the monitoring values ​​into the production process data management system, and monitor and statistically analyze the status of the frameless door system based on the production process data management system to obtain monitoring data.

[0062] S3: The monitoring data is correlated with the tooling automatic adjustment data to obtain the pre-adjustment amount, and the frameless door glass is adjusted according to the pre-adjustment amount. The pre-adjustment amount actually includes two quantities: for the tooling, it realizes the X, Y, and Z-axis position of the glass; for the door, the glass and the tooling are adjusted together. The glass regulator and sealing strip are pre-adjusted during the parts production process.

[0063] It should be noted that the tooling in this application is a device installed on the car door to adjust the position of the glass and achieve glass positioning. At the same time, the tooling is equipped with a position sensor, which can be used to measure the X, Y and Z position of the glass.

[0064] Furthermore, in one embodiment, the monitoring data is correlated with the tooling automatic adjustment data to obtain a pre-adjustment amount, and the frameless door glass is adjusted according to the pre-adjustment amount, specifically including:

[0065] S301: Based on the monitoring data results of key monitoring characteristics, and according to the influence factor relationship between the frameless door system function and key monitoring characteristics, identify the positive or negative impact of each key monitoring characteristic on the frameless door system function.

[0066] In this application, the expression for the influencing factor relationship between the frameless door system function and key monitoring characteristics is as follows:

[0067] Y(i)=aX1(i)+bX2(i)+cX3(i)+dX4(i)+eX5(i)+fX6(i)+gX7(i)+……

[0068] Where Y(i) represents the performance parameter corresponding to the i-th function of the frameless door system, X1(i), X2(i), X3(i), ... represent the key monitoring characteristic parameters that affect the i-th function of the frameless door system, and a, b, c, etc. represent the weighting coefficients of the key monitoring characteristics on the function.

[0069] S302: Perform balance calculations on the frameless door system based on the positive or negative impact results to obtain the clearance fit requirements between the frameless door glass and surrounding components.

[0070] Based on the relationship between the influencing factors of the frameless door system function and key monitoring characteristics, the positive or negative impact of each key monitoring characteristic on the frameless door system function is identified, thereby performing a performance index balance calculation of the frameless door system function and obtaining the clearance fit requirements between the frameless door glass and the surrounding environmental components.

[0071] S303: Based on the clearance fit requirements between the frameless door glass and the surrounding environmental parts, the tooling adjustment target value is obtained, and the tooling adjustment target value is compared with the tooling adjustment default value to obtain the tooling pre-adjustment amount;

[0072] S304: Adjust the frameless door glass based on the pre-adjustment amount of the obtained tooling.

[0073] The following example illustrates the relationship between the influencing factors of the frameless door system's functions and key monitoring characteristics.

[0074] For example, the sealing function Y(M), lifting function Y(S), and closing function Y(G) include a performance parameter called closing force Y(gg), which involves two key monitoring characteristics: (1) X1(g) the compression load of the sealing strip. This key monitoring characteristic is monitored during the production process of the sealing strip, and the data is synchronized to the adaptation system; (2) the compression amount of the sealing strip. This key monitoring characteristic is further decomposed into X2(g) and X3(g). X2(g) is the position of the glass in the Y direction of the door (adjusted on the glass adjustment fixture), and X3(g) is the installation position of the sealing strip on the side panel (monitored on the production line of the welding workshop of the vehicle manufacturing plant, and the data is synchronized to the system).

[0075] By monitoring key monitoring characteristics, the values ​​of X1(g) and X3(g) can be identified in advance, based on the closing force Y(gg) = a X1(g) * [b X2(g), c X3(g)];

[0076] Y(gg) is a nominal requirement value designed to meet the closing function Y(G). To meet this requirement value, given the values ​​of X1(g) and X3(g), the value of X2(g) can be calculated. This value is output to the tooling as the target value. The tooling is adjusted based on the difference between the input target value and the preset value. This allows the tooling to be pre-adjusted to match the measured values ​​of the door and side panel, thus actively pre-matching and reducing manual adjustments.

[0077] Furthermore, in one embodiment, the method for determining the default value of the tooling adjustment includes:

[0078] S311: By using the adjustment fixture for the frameless door system, the frameless door glass is pre-adjusted to obtain the relationship between the influencing factors of the frameless door system function and key monitoring characteristics. Assembly verification is then performed on the set door system environmental components to correct the relationship between the influencing factors. The set door system environmental components include standard-sized body panels, A / B / C pillar trim panels, etc.

[0079] S312: Based on the corrected relationship of influencing factors, the results are verified on a real vehicle, and key monitoring characteristics are adjusted based on the verification results to continuously and proactively adjust the tooling adjustment amount.

[0080] S313: When the tooling adjustment result meets the target requirements, the default tooling adjustment value is obtained based on the cumulative value of the tooling adjustment amount.

[0081] The X, Y, and Z-axis values ​​of the glass adjusted by the tooling need to be correlated with the corresponding influencing factors. This involves setting the coefficients in the influencing factor relationship between the tooling adjustment values ​​and functional assurance. This process mainly consists of three steps:

[0082] Step 1: Validation on standard vehicle bodies and doors. Based on the frameless door glass adjustment fixture, pre-adjustment of the frameless door glass is carried out to achieve matching with surrounding components, reducing the passive adjustment time for each door and the rework time after production.

[0083] Before the glass tooling was first used, the upper, middle and lower limits of the design of each component were implemented on the standard door and body to verify whether the currently designed components could meet the implementation of the frameless door system function. The influence factors of each purchased component on the frameless door system function were decomposed, and the frameless door system design was modified and verified.

[0084] The glass tooling of the same batch of parts and the same batch of inspected door panels are calibrated. After calibration, the parts are then assembled and verified on standard door panels and body panels to further correct the coefficients in the influencing factor relationships and to verify the adjustment amount of the tooling. After at least three batches of parts, the calibration of the default adjustment values ​​and judgment criteria for the glass tooling can be preliminarily completed.

[0085] Step 2: Verification on a real vehicle. Based on the process stability of parts in the same batch, and to maximize work efficiency, full inspection of every door and every part is not adopted. Since the key monitoring characteristics are based on the inspection of each batch of parts, rather than all parts, considering the dispersion of parts and the insufficient accuracy of the influencing factors between functions and key monitoring characteristics, the initial use of pre-adjustment amounts may not be 100% compatible with the state of each door on the production line. For those that are incompatible, the real-time detection value on the glass adjustment fixture (equipped with a displacement sensor to automatically measure distance) will report an error (a red alarm will appear). At this point, on-site personnel need to manually adjust the fixture. In this situation, the adjustment amounts can be recorded and accumulated, and analyzed in relation to the key monitoring characteristics to identify the points of difference affecting the process. Based on the adjustable and flexible design of the frameless door glass adjustment method, corresponding adjustments can be made to the key monitoring characteristics to reduce errors.

[0086] Based on this characteristic, at least 10 batches need to be continuously tested to fully identify the variance of the frameless door system and the coefficient changes of functional influencing factors. After design-decomposition-monitoring-adjustment-verification, the calculated coefficients of the frameless door system can be corrected. At the same time, by combining the variance probability distribution, the automatic adjustment accuracy of the frameless door glass adjustment method can be continuously improved. Implementing a default door glass adjustment state can reduce or even avoid most of the adjustment time for frameless door glass.

[0087] Step 3: Adjustment after mass production. Based on the accumulated adjustment records of manual tooling adjustments made by on-site personnel after errors were reported on the glass adjustment fixture, the relationship coefficients of various influencing factors and the tooling adjustment coefficients are continuously corrected to reduce errors and ultimately achieve near 100% automatic adjustment.

[0088] The process of obtaining the default values ​​for tooling adjustments involves three steps: gradually adapting key monitoring characteristic values. The first step is to directly use the parts produced by the OEM as the standard state to verify the adjustments of purchased parts and glass tooling. This is a more idealistic adaptation because there are too many variables in the frameless door system when adding the parts produced by the OEM. Therefore, the first step is performed first. After a preliminary confirmation of the coefficients of the formula, the actual measured side panels and doors of the OEM are added for verification. At this point, the coefficients can be corrected again.

[0089] Besides the pre-set glass settings, there's another situation where the glass can't be adjusted further. In this case, we need to examine the actual components in the door to see which ones require adjustment. This is where flexible design comes in. For example, if the Y-axis tooling has reached its limit, we can activate the following flexible design to reduce the amount of tooling adjustment:

[0090] The adjustable window regulator bolts (adaptable to the Y-axis of the window regulator and door glass in the door system, with flexible tolerance) utilize a double-ended bolt structure to achieve adjustable window regulator bolts. Upper bolt adjustment: unscrew 3.0±0.5mm, screw in 2.5±0.5mm; Lower bolt adjustment: unscrew 7.5±0.5mm, screw in 5.5±0.5mm.

[0091] This application decomposes the functional objectives of the frameless door system and then conducts daily management to proactively identify the functional objective status of the door, rather than passively accepting the status of the door. The management of daily data can identify whether the door meets the requirements, and the conclusion of whether each batch needs to be reworked can be understood in advance, so that adjustments can be made on the production line to reduce or even avoid rework after production.

[0092] This application employs a flexible design (requiring the resolution of key conflict points and difficult-to-control items), adaptable to the tolerance fluctuations of the production process (with compensation), and ensures the system achievement of various performance targets (gap surface difference, sealing, lifting, opening and closing) (compatibility design balancing various performance contradictions); for the key monitoring characteristics and system balancing methods of frameless door system target decomposition, the influence factor relationship coefficient between key monitoring characteristics and functions, and the identification of characteristic item types: stable and important, fluctuating and important, stable and unimportant, and fluctuating and unimportant, implementing different monitoring strategies; for the method of associating key characteristic monitoring data with tooling adjustment, the corresponding parameters between tooling preset values ​​and functions, and the matching between key monitoring characteristic values ​​and tooling preset parameters; it can realize automatic detection (detection positioning - sensor - data standard setting) and automatic adjustment (self-correction based on the measured values ​​of key characteristic monitoring to meet the functions).

[0093] Secondly, embodiments of this application also provide a frameless car door glass adjustment device.
