Description

Technical Field

[0001] This application relates to, but is not limited to, the field of vehicle assembly technology, and particularly to a method, apparatus, electronic device, and storage medium for assembling a vehicle trunk lid. Background Technology

[0002] With the development of vehicle assembly technology, the assembly of the four doors and two covers of a vehicle with the vehicle body is now mostly carried out using automated assembly lines. Since there is no direction to absorb tolerances when assembling the trunk lid (also known as the trunk cover) with the vehicle body, the requirements for the assembly of the trunk lid with the vehicle body are higher, and the trunk lid needs to match the height of the vehicle body.

[0003] In the assembly solutions provided by related technologies, the initial pass rate of the trunk lid assembly to the vehicle body is low, and the assembly quality is unstable. After automated assembly, a large proportion requires manual adjustment, which wastes manpower and time. Summary of the Invention

[0004] In view of this, embodiments of this application provide a method, apparatus, electronic device, and storage medium for controlling the assembly of a vehicle trunk lid. The method for controlling the assembly of a vehicle trunk lid provided in this application can significantly improve the assembly quality of the trunk lid and stabilize the assembly quality, thereby significantly increasing the initial pass rate of the trunk lid and improving the assembly efficiency of the trunk lid.

[0005] The technical solution of this application embodiment is implemented as follows:

[0006] On one hand, embodiments of this application provide a method for controlling the assembly of a vehicle trunk lid, the method comprising:

[0007] After the test trunk lid is assembled onto the vehicle body and adjusted to the reference position, obtain the reference position information of different parts of the test trunk lid relative to the vehicle body;

[0008] During the process of assembling the current trunk lid to the vehicle body, the actual position information of different parts of the current trunk lid relative to the vehicle body is obtained;

[0009] Adjust the current position of the trunk lid relative to the vehicle body so that the deviation between the actual position information and the reference position information meets the preset conditions.

[0010] On the other hand, embodiments of this application provide a vehicle trunk lid assembly control device, including:

[0011] The first acquisition module is used to acquire the reference position information of different parts of the test luggage compartment cover relative to the vehicle body after the test luggage compartment cover is assembled onto the vehicle body and adjusted to the reference position;

[0012] The second acquisition module is used to acquire, during the process of assembling the current trunk lid to the vehicle body, the actual position information of different parts of the current trunk lid corresponding to the reference position information relative to the vehicle body;

[0013] The first adjustment module is used to adjust the current position of the trunk lid relative to the vehicle body so that the deviation between the actual position information and the reference position information meets the preset conditions.

[0014] In another aspect, embodiments of this application provide an electronic device, including a memory and a processor, wherein the memory stores a computer program that can run on the processor, and the processor executes the computer program to implement the steps in the above-described method.

[0015] In another aspect, embodiments of this application provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps in the above-described method.

[0016] In this embodiment, the position information of the test luggage box relative to the vehicle body after it has been assembled to the vehicle body and adjusted to the reference position is first measured as a reference standard to guide the subsequent assembly of the luggage box. Compared with the related technology that simply mechanically adjusts the position of the luggage box cover relative to the vehicle body by the gap value or surface difference value between different parts of the luggage box cover and the vehicle body being less than or equal to a certain standard value, the vehicle luggage box cover assembly control method provided in this embodiment can significantly improve the assembly quality of the luggage box cover and make the assembly quality of the luggage box cover stable, which can significantly improve the initial assembly pass rate of the luggage box cover and improve the assembly efficiency of the luggage box cover.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application are further described in detail below with reference to the accompanying drawings and embodiments. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0028] If the application documents contain similar descriptions such as "first / second", the following explanation shall be added: In the following description, the terms "first / second / third" are used only to distinguish similar objects and do not represent a specific order of objects. It is understood that "first / second / third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0030] This application provides a method for controlling the assembly of a vehicle trunk lid, which can be applied to the assembly of vehicles equipped with trunk lids. It should be noted that this application does not limit the type of vehicle; the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles.

[0031] With the development of vehicle assembly technology, automated assembly technology is now widely used to assemble the four doors and two panels of a vehicle to the vehicle body. The assembly quality between the four doors and two panels and the vehicle body is mainly characterized by the magnitude of the gaps and surface differences. For example, the assembly quality between the trunk lid and the body can be characterized by the gap between the trunk lid and the body, as well as the surface difference between the trunk lid and the body.

[0032] In the assembly solutions provided by relevant technologies for trunk lids and vehicle bodies, the position of the trunk lid relative to the vehicle body is generally adjusted mechanically based on whether the gap or surface difference between different parts of the trunk lid and the vehicle body is less than or equal to a certain standard value. However, due to manufacturing errors in the trunk lid or vehicle body, it is possible that the gap or surface difference between different parts of the trunk lid and the vehicle body may not simultaneously be less than or equal to the standard value. This can lead to a low initial assembly pass rate and unstable quality of the trunk lid after assembly. Even after automated assembly of the trunk lid to the vehicle body, a significant portion still requires manual adjustment, wasting manpower and time.

[0033] Therefore, this application provides a vehicle trunk lid assembly control method. In this method, the position of a test trunk lid after it has been assembled to the vehicle body and adjusted to a reference position is measured as a reference standard to guide subsequent trunk lid assembly. Compared to related technologies that mechanically adjust the trunk lid's position relative to the vehicle body based on whether the gap or surface difference between different parts of the trunk lid and the vehicle body is less than or equal to a certain standard value, this method significantly improves the assembly quality of the trunk lid, stabilizes the assembly quality, significantly increases the initial assembly pass rate, and improves the assembly efficiency.

[0034] It should be noted that the vehicle trunk lid assembly method provided in this application embodiment can be executed by an electronic device, which can be various types of terminals such as in-vehicle devices, laptops, tablets, desktop computers, set-top boxes, and mobile devices (e.g., mobile phones, portable music players, personal digital processors, dedicated messaging devices, portable gaming devices), or it can be implemented as a server. The server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (CDN), and big data and artificial intelligence platforms.

[0035] Based on this, Figure 1 A flowchart illustrating the implementation of a vehicle trunk lid assembly control method provided in this application embodiment is shown below. Figure 1 As shown, the method includes steps S11 to S13, wherein:

[0036] Step S11: Obtain the reference position information of different parts of the test luggage compartment cover relative to the vehicle body after it has been assembled onto the vehicle body and adjusted to the reference position.

[0037] It should be noted that in the vehicle trunk lid assembly control method provided in this application embodiment, one or more trunk lids can first be assembled to the vehicle body to accumulate experience and establish references, which can then guide the assembly of subsequent trunk lids. Therefore, the trunk lid used for accumulating experience and establishing references can be referred to as the test trunk lid, and the subsequently assembled trunk lid can be referred to as the current trunk lid.

[0038] Here, the test trunk lid can first be manually installed onto the vehicle body and manually adjusted so that the test trunk lid is in the reference position relative to the vehicle body.

[0039] It should be noted that the reference position of the test trunk lid relative to the vehicle body here refers to the position of the test trunk lid relative to the vehicle body when the combined deviation of the gap and surface difference between the test trunk lid and the vehicle body is at its minimum.

[0040] Here, one or more reference points can be selected on the vehicle body as a reference for evaluating the position of the test trunk lid relative to the vehicle body. The three-dimensional coordinates of this reference point can be obtained beforehand for evaluating the position of the test trunk lid relative to the vehicle body. Correspondingly, some measurement points can be selected at different locations on the test trunk lid. By obtaining the three-dimensional coordinates of these measurement points after the trunk lid is assembled to the vehicle body and adjusted to the reference position, and comparing the three-dimensional coordinates of the measurement points with the three-dimensional coordinates of the reference points, the reference position information of the test trunk lid relative to the vehicle body, represented by three-dimensional coordinates, can be obtained.

[0041] Alternatively, using the vehicle body as a reference, the positional information of certain parts of the test trunk lid relative to the vehicle body can be directly measured after the test trunk lid is assembled to the vehicle body and adjusted to the reference position, such as gaps and surface differences. In this way, reference positional information of the test trunk lid relative to the vehicle body, characterized by gaps and surface differences, can be obtained.

[0042] The quality of a trunk lid's assembly to the vehicle body is generally characterized by the gap and surface difference between the trunk lid and the body. However, continuously measuring these gaps and surface differences to characterize the quality of the trunk lid's assembly is impractical. In engineering practice, representative areas on the trunk lid are selected, and the gaps and surface differences between these representative areas and the body are measured to characterize the quality of the trunk lid's assembly.

[0043] In this regard, the gaps and surface differences between the aforementioned representative parts and the vehicle body can also be used to characterize whether the test trunk lid is in a reference position relative to the vehicle body.

[0044] For example, the corners of the trunk lid can be selected as representative locations. The surface difference between these corners and the vehicle body is measured, and the trunk lid's position relative to the vehicle body can be determined using any one of the following surface difference values: difference / ratio / mean / variance / standard deviation. Specifically, assuming the surface differences between the corners of the trunk lid and the vehicle body are a, b, c, and d, the position of the trunk lid relative to the vehicle body when the mean of a, b, c, and d is minimized can be used as the reference position.

[0045] It should be noted that the test trunk lid can be confirmed to be in the reference position relative to the vehicle body by repeatedly adjusting the position of the test trunk lid relative to the vehicle body and measuring the gap and surface difference between the aforementioned representative parts and the vehicle body.

[0046] Based on this, after installing the test trunk lid onto the vehicle and adjusting it to the reference position, the reference position information of different parts of the test trunk lid relative to the vehicle body can be obtained by measuring the position information of different parts of the test trunk lid relative to the vehicle body.

[0047] In addition, in this embodiment of the application, the position information of the test trunk lid can be measured using the vehicle body as a reference frame, thereby obtaining the reference position information of different parts of the test trunk lid relative to the vehicle body; in addition, a third party other than the trunk lid and the vehicle body can be selected as a reference frame to measure the position information of the test trunk lid and the position information of the vehicle body respectively. After conversion, the reference position information of different parts of the test trunk lid relative to the vehicle body can also be obtained.

[0048] This application does not limit the method for obtaining the reference position information of different parts of the test trunk lid relative to the vehicle body. For example, the reference position information of different parts of the test trunk lid relative to the vehicle body can be obtained manually by a surveyor, such as by using a gap gauge, feeler gauge, or surface difference gauge to measure the gap or surface difference between the test trunk lid and the vehicle body. Alternatively, a three-dimensional scanning or measurement system, such as a laser gap / surface difference measuring instrument, can be used to measure the gap or surface difference between the test trunk lid and the vehicle body.

[0049] In some embodiments of this application, to ensure the accuracy of the reference position information of different parts of the test trunk lid relative to the vehicle body, multiple test trunk lids can be set, for example, more than 10 test trunk lids can be set. Furthermore, by measuring the reference position information of different parts of each test trunk lid relative to the vehicle body, multiple reference position information is obtained. Further, the average value of these multiple reference position information is calculated and used as the final reference position information of different parts of the trunk lid relative to the vehicle body.

[0050] Step S12: During the process of assembling the current trunk lid to the vehicle body, obtain the actual position information of different parts of the current trunk lid corresponding to the reference position information relative to the vehicle body.

[0051] It should be noted that, in the embodiments of this application, the current trunk lid can be assembled to the vehicle body manually; or it can be automatically assembled to the vehicle body using an automated assembly line. The embodiments of this application do not limit this to either method.

[0052] Furthermore, this application embodiment does not limit the method for obtaining the actual position information of the trunk lid relative to the vehicle body. For example, the actual position information of the trunk lid relative to the vehicle body can be obtained by manual measurement by surveyors or by using a three-dimensional scanning or measurement system, referring to the above-mentioned method for obtaining reference position information.

[0053] It should be noted that the different parts of the current trunk lid relative to the actual position information of the vehicle body correspond one-to-one with the different parts of the test trunk lid relative to the reference position information of the vehicle body. For example, if the part of the test trunk lid used to determine the difference from the reference position information of the vehicle body refers to the four corners of the test trunk lid, then for the current trunk lid, the part used to determine the difference from the actual position information of the vehicle body also refers to the four corners of the current trunk lid. Based on this, it can be understood that the part on the current trunk lid used to determine the actual position information of the current trunk lid relative to the vehicle body and the part on the test trunk lid used to determine the reference position information of the test trunk lid relative to the vehicle body refer to the same part of the trunk lid.

[0054] Step S13: Adjust the current position of the trunk lid relative to the vehicle body so that the deviation between the actual position information and the reference position information meets the preset conditions.

[0055] Thus, based on the reference position information of the test trunk lid relative to the vehicle body obtained in the aforementioned steps, this reference position information can be used as a reference during the trunk lid assembly process to guide the current trunk lid assembly. Specifically, the actual position information of the current trunk lid relative to the vehicle body can be compared with the reference position information of the test trunk lid relative to the vehicle body to serve as a reference for adjusting the current trunk lid's position relative to the vehicle body during the assembly process.

[0056] Based on this, preset conditions can be set for the actual position information of the trunk lid relative to the vehicle body and the reference position information of the trunk lid relative to the vehicle body during testing. If the actual position information and the reference position information meet the preset conditions, the assembly quality between the current trunk lid and the vehicle body is considered acceptable; if the actual position information and the reference position information do not meet the preset conditions, the assembly quality between the current trunk lid and the vehicle body is considered unacceptable.

[0057] For example, the difference / ratio / mean / variance / mean square deviation between the current trunk lid and the vehicle body represented by the actual position information and the current trunk lid and the vehicle body represented by the reference position information can be less than or equal to a certain preset threshold as a preset condition.

[0058] It should be noted that, for vehicle automated processing or assembly technology, products manufactured using production lines of the same specifications generally have similar manufacturing errors. In this embodiment, the position information of the test luggage box relative to the vehicle body after it has been assembled to the vehicle body and adjusted to the reference position is first measured as a reference standard to guide the subsequent assembly of the luggage box. Compared with the related technology that simply mechanically adjusts the position of the luggage box lid relative to the vehicle body by the gap value or surface difference value between different parts of the luggage box lid and the vehicle body being less than or equal to a certain standard value, the vehicle luggage box lid assembly control method provided in this embodiment can significantly improve the assembly quality of the luggage box lid and make the assembly quality of the luggage box lid stable, which can significantly improve the initial assembly qualification rate of the luggage box lid and improve the assembly efficiency of the luggage box lid.

[0059] Reference Figure 2 In some embodiments of this application, the trunk lid has a first side A extending along the length direction of the vehicle body and a second side B extending along the height direction of the vehicle body. Based on this, the representative parts of the test trunk lid are selected as the two ends of the second side B along the vehicle body direction, the two ends of the first side A on the front side along the vehicle body width direction, and the two ends of the first side A on the rear side along the vehicle body width direction.

[0060] It should be noted that the parts of the test trunk lid mentioned above relative to the vehicle body refer to the relative positions of the test trunk lid after it is assembled to the vehicle body.

[0061] Based on this, the surface difference between the aforementioned representative parts and the vehicle body is used to characterize the reference position information. That is, the reference position information of different parts of the test trunk lid relative to the vehicle body includes:

[0062] The surface difference between the two ends of the second side of the test luggage box along the width direction of the vehicle body and the vehicle body is referred to as the first reference surface difference and the second reference surface difference for ease of description.

[0063] The surface difference between the two ends of the first side of the test luggage box corresponding to the front of the car and the car body along the width direction is referred to as the third reference surface difference and the fourth reference surface difference for ease of description.

[0064] The surface difference between the first side of the test luggage box and the two ends of the rear side of the vehicle along the width direction of the vehicle body is referred to as the fourth reference surface difference and the fifth reference surface difference for ease of description.

[0065] It should be noted that the reference position information of different parts of the test trunk lid relative to the vehicle body refers to the position of the vehicle body corresponding to different parts of the test trunk lid.

[0066] For example, refer to Figure 2 To facilitate the measurement of the reference position information between the test trunk lid and the vehicle body, a cross-section can be set between a representative part of the test trunk lid and the vehicle body to facilitate the sampling of points for measuring the surface difference between the test trunk lid and the vehicle body.

[0067] Specifically, refer to Figure 2 Depending on the position of the trunk lid relative to the vehicle, the second side also refers to the side of the rear of the vehicle corresponding to the trunk lid. The aforementioned first and second reference plane differences can be expressed as... Figure 2 The position of the trunk lid relative to the vehicle body is represented by the surface difference between positions X1 and X2, where X1 and X2 represent the surface differences between the two ends of the second side along the width direction of the vehicle body and the vehicle body, respectively. The position of the trunk lid relative to the vehicle body along the length direction can be determined by the first reference surface difference and the second reference surface difference.

[0068] Reference Figure 2 The first side also refers to the side of the trunk lid corresponding to the vehicle's roof. The aforementioned third and fourth reference plane differences can be... Figure 2 The difference in surface area between positions Z3 and Z4 is used to represent the surface area difference between the two ends of the first side of the test trunk, corresponding to the front of the vehicle, along the width direction of the vehicle body. The third and fourth reference surface differences determine the position of the trunk lid, corresponding to the rear of the vehicle, along the height direction of the vehicle body.

[0069] Additionally, refer to Figure 2 The aforementioned fifth and sixth datum differences can be expressed as follows: Figure 2 The difference in surface area between positions Z1 and Z2 is used to represent this. The fifth and sixth reference surface differences can be used to determine the position of the trunk lid relative to the vehicle body along the height direction of the vehicle's body on the side corresponding to the front of the vehicle.

[0070] Through the above settings, the position of the trunk relative to the vehicle body can be controlled in multiple dimensions, maximizing the accuracy of the relative position between the trunk lid and the vehicle body. Thus, during the assembly of the trunk lid to the vehicle body, by controlling the position of the trunk lid corresponding to the first, second, third, fourth, fifth, and sixth reference surface differences, the deviation between the surface differences between the trunk lid and the vehicle body corresponding to these points and the aforementioned reference surface differences meets preset conditions, ensuring that the assembly of the trunk lid to the vehicle body is qualified.

[0071] Based on this, when assembling the current trunk lid, the position of the current trunk lid relative to the vehicle body is measured using the corresponding parts of the current trunk lid and the test trunk lid. That is, the actual position information of different parts of the aforementioned current trunk lid corresponding to the reference position information relative to the vehicle body includes:

[0072] The surface difference between the two ends of the second side of the current luggage compartment along the width direction of the vehicle body and the vehicle body is referred to as the first actual surface difference and the second actual surface difference for ease of description.

[0073] The surface difference between the two ends of the first side of the current luggage compartment corresponding to the front of the car along the width direction of the car body and the car body is referred to as the third actual surface difference and the fourth actual surface difference for ease of description.

[0074] The surface difference between the two ends of the first side of the current trunk corresponding to the rear of the vehicle along the width direction of the vehicle body and the vehicle body is, for ease of description, divided into the fourth actual surface difference and the fifth actual surface difference.

[0075] Based on this, during the process of assembling the current trunk lid to the vehicle body, the first actual surface difference and the first reference surface difference, the second actual surface difference and the second reference surface difference, the third actual surface difference and the third reference surface difference, the fourth actual surface difference and the fourth reference surface difference, the fifth actual surface difference and the fifth reference surface difference, and the sixth actual surface difference and the sixth reference surface difference are compared respectively. The position of the current trunk lid relative to the vehicle body is adjusted so that the deviation between the above-mentioned actual surface differences and the corresponding reference surface differences meets the preset conditions. In this way, it can be ensured that the current trunk lid is properly assembled with the vehicle body.

[0076] In addition, compared to using parameters such as ratio / mean / variance / mean square deviation as preset conditions, in some embodiments of this application, using the difference as preset conditions makes it more direct to judge the magnitude of the deviation between the actual surface difference and the reference surface difference.

[0077] Specifically, this application also provides a method for controlling the assembly of a vehicle trunk lid, referring to... Figure 3 The flowchart below shows a method for assembling and controlling a vehicle trunk lid, as provided in an embodiment of this application. Figure 3 As shown, the method includes steps S21 to S23, wherein:

[0078] Step S21: Obtain the reference position information of different parts of the test trunk lid relative to the vehicle body after the test trunk lid is installed on the vehicle body and adjusted to the reference position.

[0079] Step S22: During the process of assembling the current trunk lid to the vehicle body, obtain the actual position information of different parts of the current trunk lid corresponding to the reference position information relative to the vehicle body.

[0080] Here, steps S21 and S22 correspond to steps S11 and S12 mentioned above. In implementation, the specific implementation methods of steps S11 and S12 mentioned above can be referred to.

[0081] Step S23: Adjust the position of the current trunk lid relative to the vehicle body so that the absolute value of the difference between the first actual surface difference and the first reference surface difference is less than or equal to a first preset threshold, the absolute value of the difference between the second actual surface difference and the second reference surface difference is less than or equal to a second preset threshold, the absolute value of the difference between the third actual surface difference and the third reference surface difference is less than or equal to a third preset threshold, and the absolute value of the difference between the average of the fifth actual surface difference and the sixth actual surface difference and the average of the fifth reference surface difference and the sixth reference surface difference is less than or equal to a fourth preset threshold.

[0082] It should be noted that, in this embodiment, the values ​​of the first, second, third, and fourth preset thresholds are not limited. The values ​​can be set by comprehensively considering the assembly precision of the trunk lid to the vehicle body. When high assembly precision is required, the values ​​of the first, second, third, and fourth preset thresholds can be set smaller; when low assembly precision is required, the values ​​of the first, second, third, and fourth preset thresholds can be set larger.

[0083] In addition, in this embodiment, the values ​​of the first preset threshold, the second preset threshold, the third preset threshold, and the fourth preset threshold can be set to be the same; or, taking into account the characteristics of different parts of the trunk lid, the first preset threshold, the second preset threshold, the third preset threshold, and the fourth preset threshold can be specially set for different parts of the current trunk lid. In this case, the values ​​of the first preset threshold, the second preset threshold, the third preset threshold, and the fourth preset threshold may be different.

[0084] In this embodiment of the application, it should be specifically noted that the comparison between the fifth and sixth actual surface differences and the fifth and sixth reference surface differences is a comprehensive consideration. That is, the average value of the fifth and sixth actual surface differences is compared with the average value of the fifth and sixth reference surface differences, and the absolute value of the difference between the average value of the fifth and sixth actual surface differences and the average value of the fifth and sixth reference surface differences is less than or equal to the fourth preset threshold.

[0085] It needs to be explained that, for a planar structure, three points can define a plane. However, for the first side of the trunk lid, it can be considered... Figure 2 The location of the trunk lid can be completely determined by three of the four parts Z1, Z2, Z3, and Z4. It should be noted that Z1 and Z2 represent the surface difference between the two ends of the first side corresponding to the rear of the vehicle along the width direction of the vehicle body and the body.

[0086] Meanwhile, due to manufacturing errors or other factors, one part may not be on the same plane as the other three parts. If the trunk lid is positioned using the positions of four parts (Z1, Z2, Z3, and Z4) relative to the vehicle body, it may be impossible for all four parts to simultaneously meet the assembly standards. For example, in related technologies, using the positions of the corresponding parts (Z1, Z2, Y3, and Y4) relative to the vehicle body to position the trunk lid may theoretically prevent the trunk lid from being adjusted to the correct position. It should be noted that Y3 and Y4 represent the gaps between the middle part of the edge of the first side of the trunk lid along the width direction of the vehicle and the vehicle body.

[0087] Therefore, in this embodiment, the average of the fifth and sixth actual surface differences is compared with the average of the fifth and sixth reference surface differences. This is equivalent to using the average of the third, fourth, and fifth and sixth actual surface differences to determine the current position of the trunk lid, which is similar to using three points to determine the first side surface.

[0088] In this way, while ensuring accurate positioning of the current trunk lid, the efficiency of positioning the current trunk lid is improved, which further enables the vehicle trunk lid assembly control method provided in this application embodiment to significantly improve the assembly quality of the trunk lid and stabilize the assembly quality of the trunk lid, thereby significantly improving the initial assembly pass rate of the trunk lid and increasing the assembly efficiency of the trunk lid.

[0089] Based on this, in order to further control the position of the trunk lid relative to the vehicle body and improve the assembly quality between the trunk lid and the vehicle body, this application embodiment also provides a vehicle trunk lid assembly control method, referring to... Figure 4The flowchart below shows a method for assembling and controlling a vehicle trunk lid, as provided in an embodiment of this application. Figure 4 As shown, the method includes steps S31 to S35, wherein,

[0090] Step S31: Obtain the reference position information of different parts of the test trunk lid relative to the vehicle body after the test trunk lid is installed on the vehicle body and adjusted to the reference position.

[0091] Step S32: During the process of assembling the current trunk lid to the vehicle body, obtain the actual position information of different parts of the current trunk lid corresponding to the reference position information relative to the vehicle body.

[0092] Here, steps S31 and S32 correspond to steps S11 and S12 mentioned above. In implementation, the specific implementation methods of steps S11 and S12 mentioned above can be referred to.

[0093] Step S33: Obtain the first actual gap and the second actual gap between the left and right ends of the rear end of the current trunk lid along the length direction of the vehicle and the vehicle body.

[0094] Here, during the process of assembling the trunk lid to the vehicle body, the first actual gap and the second actual gap between the left and right ends of the rear end of the trunk lid along the length of the vehicle and the vehicle body are also measured, and the first actual gap and the second actual gap are used as one of the factors to measure the assembly quality between the trunk lid and the vehicle body.

[0095] It should be noted that the parts used to measure the first and second actual clearances between the trunk lid and the vehicle body are symmetrical along the length of the vehicle body. When the trunk lid is in its theoretical assembly position relative to the vehicle body, the first and second actual clearances should be the same.

[0096] Furthermore, in this embodiment, the method of obtaining the first and second actual gaps is not limited. For example, the first and second actual gaps can be obtained manually by a surveyor, such as using a gap gauge or feeler gauge. Alternatively, a three-dimensional scanning or measurement system, such as a laser gap difference measuring instrument, can be used to measure the first and second actual gaps.

[0097] In some embodiments of this application, in order to facilitate the measurement of the surface difference and gap between the current trunk and the vehicle body and improve the measurement efficiency, the parts of the current trunk lid used for measuring the first and second actual gaps with the vehicle body can be combined with the parts of the current trunk lid used for measuring the surface difference with the vehicle body.

[0098] For example, refer to Figure 2 The locations on the left and right ends of the rear end of the current trunk lid along the vehicle's length direction, used for measuring the third and fourth actual surface differences with the vehicle body, can be placed on the same cross-section as the locations on the left and right ends of the rear end of the current trunk lid along the vehicle's length direction, used for measuring the first and second actual gaps with the vehicle body. (Refer to...) Figure 2 The aforementioned first and second actual gaps can be... Figure 2 It is represented by the gap between positions Y1 and Y2.

[0099] Step S34: Adjust the current position of the trunk lid relative to the vehicle body so that the deviation between the actual position information and the reference position information meets the preset conditions.

[0100] Here, step S34 above corresponds to step S13 above. When implementing it, you can refer to the specific implementation method of step S13 above.

[0101] Step S35: Adjust the position of the current trunk lid relative to the vehicle body so that the deviation between the first actual gap and the second actual gap is less than or equal to the fifth preset threshold.

[0102] Based on the first and second actual gaps obtained in the aforementioned steps, the numerical values ​​of the first and second actual gaps can be used as factors to measure the assembly quality between the trunk lid and the vehicle body.

[0103] Specifically, a threshold can be preset so that the deviation between the first actual gap and the second actual gap is less than the threshold. For ease of description, this threshold can be called the fifth preset threshold.

[0104] It should be noted that the deviation between the first actual gap and the second actual gap being less than the fifth preset threshold means that the absolute value of the difference between the first actual gap and the second actual gap is less than or equal to the fifth preset threshold.

[0105] Furthermore, in this embodiment, the specific value of the fifth preset threshold is not limited. It can be set considering the assembly precision required for the luggage lid to fit the body; when high assembly precision is required, the fifth preset threshold can be set smaller; when low assembly precision is required, the fifth preset threshold can be set larger.

[0106] For example, in some embodiments of this application, the fifth preset threshold can be set to 0.5 mm. If y1 represents the first actual gap and y2 represents the second actual gap, then the deviation between the first and second actual gaps being less than or equal to the second preset threshold can be expressed by the following formula:

[0107] |y1-y2|≤0.5mm

[0108] Thus, in the vehicle trunk lid assembly control method provided in this application embodiment, by controlling the first actual gap and the second actual gap between the current trunk lid and the vehicle body, the deviation between the first actual gap and the second actual gap is less than or equal to a fifth preset threshold, which can further ensure the quality of the current trunk lid assembly to the vehicle body.

[0109] Additionally, to ensure the trunk lid can be opened or closed relative to the vehicle body, refer to Figure 5 and Figure 6 The connection between the trunk lid and the vehicle body is generally via a hinge. One end of the hinge is fixedly connected to the vehicle body; for ease of description, this end can be referred to as the fixed hinge (51). The other end of the hinge is fixedly connected to the trunk lid; for ease of description, this end can be referred to as the movable hinge (52). Fasteners are typically provided on both the fixed and movable hinges. Connection holes can be provided on the vehicle body and the trunk lid, respectively. The connection between the fasteners and these connection holes secures the fixed hinge to the vehicle body and the movable hinge to the trunk lid. (See reference...) Figure 5 The hinge's position relative to the vehicle along its height direction can be defined by using the connection surface between the hinge's fixing hinge and the vehicle body as the hinge's body-side mounting surface 53. Meanwhile, referring to... Figure 6 Multiple positioning holes 54 can be provided on the fixed page of the hinge to define the position of the hinge relative to the vehicle along the length direction and the width direction of the vehicle.

[0110] Additionally, refer to Figure 5 In some embodiments of this application, an elongated adjustment hole 55 may be provided between the fixed and movable pages of the hinge to adjust the opening between the fixed and movable pages of the hinge.

[0111] Furthermore, to meet the assembly tolerance requirements between the vehicle body and the fixed flap, and to allow for relative adjustment of the fixed flap's position relative to the vehicle body, the connecting holes on the vehicle body are generally slightly larger than the fasteners. Similarly, to meet the assembly tolerance requirements between the trunk lid and the movable flap, and to allow for relative adjustment of the movable flap's position relative to the trunk lid, the connecting holes on the vehicle body are generally slightly larger than the fasteners.

[0112] In addition, during the process of assembling the trunk lid to the vehicle body, the hinges are usually assembled to the trunk lid first, and then the trunk lid and hinge assembly is assembled to the vehicle body together.

[0113] Therefore, the assembly quality between the hinges and the trunk lid will also affect the assembly quality between the trunk lid and the vehicle body.

[0114] Therefore, this application also provides a method for controlling the assembly of a vehicle trunk lid, referring to... Figure 7 The flowchart below shows a method for assembling and controlling a vehicle trunk lid, as provided in an embodiment of this application. Figure 7 As shown, the method includes steps S41 to S45, wherein:

[0115] Step S41: Obtain the reference position information of different parts of the test trunk lid relative to the vehicle body after the test trunk lid is installed on the vehicle body and adjusted to the reference position.

[0116] Here, step S41 corresponds to step S11 mentioned above. In implementation, the specific implementation method of step S11 mentioned above can be referred to.

[0117] Step S42: Obtain the reference position information of the test trunk lid relative to the hinge after it has been installed on the vehicle body and adjusted to the reference position.

[0118] It should be noted that, since the test trunk lid was installed after the vehicle body, the space between the trunk lid and the hinge was small, making it inconvenient to measure the position of the hinge relative to the trunk lid.

[0119] In some embodiments of this application, after the test trunk lid is installed on the vehicle body and adjusted to a reference position, the fasteners between the hinge's fixed leaf and the vehicle body are removed, and the relative positional relationship between the hinge's movable leaf and the trunk lid is measured.

[0120] At this point, the relative position between the hinge's moving flap and the trunk lid can also be referred to as the reference relative position between the hinge and the trunk lid. This relative position can then be used as a reference to guide subsequent assembly between the trunk lid and the hinge.

[0121] Step S43: During the process of assembling the current trunk lid to the vehicle body, obtain the actual position information of different parts of the current trunk lid corresponding to the reference position information relative to the vehicle body.

[0122] Here, step S43 corresponds to step S12 mentioned above. In implementation, the specific implementation method of step S12 mentioned above can be referred to.

[0123] Step S44: Adjust the current position information of the current trunk lid relative to the hinge so that the deviation between the current position information and the reference position information meets a preset range.

[0124] For example, when using a hinge fixture to assemble the hinge to the trunk lid, a test trunk lid can first be manually installed onto the vehicle body and manually adjusted until it is in a reference position relative to the vehicle body. Then, the relative positional relationship between the hinge and the trunk lid can be marked by drawing lines at the connection point.

[0125] Then, remove the hinge from the trunk lid and use a hinge fixture to reinstall the hinge onto the trunk lid. At this point, the hinge fixture can be adjusted so that the deviation between the position of the hinge assembled onto the trunk lid using the hinge fixture and the relative position of the hinge and the trunk lid determined by marking lines meets the preset conditions.

[0126] It should be noted that, in some embodiments of this application, when positioning the hinge and trunk lid, the part on the trunk lid used to measure the relative position with respect to the hinge can be selected as the same part on the trunk lid used to measure the relative position with respect to the vehicle body. This allows the reference position for assembling the hinge onto the trunk lid to be consistent with the reference position for assembling the trunk lid and hinge assembly onto the vehicle body, reducing the influence of extra-large chain links during assembly.

[0127] Step S45: Adjust the current position of the trunk lid relative to the vehicle body so that the deviation between the actual position information and the reference position information meets the preset conditions.

[0128] Here, step S45 corresponds to step S13 mentioned above. In implementation, the specific implementation method of step S13 mentioned above can be referred to.

[0129] It should be noted that, in this embodiment, the actual position information between different parts of the current trunk lid and the vehicle body can be obtained by manual measurement, or the actual position information between different parts of the test trunk lid and the vehicle body can be obtained by manual measurement. Alternatively, a contact-type coordinate measuring machine can be used to measure the reference position information and the actual position information.

[0130] In addition, in some embodiments of this application, a vision system can be used to obtain reference position information and actual position information.

[0131] Specifically, one or more cameras can be set up to scan the areas where surface differences or gaps need to be measured. By extracting the set of surface difference points of the areas to be measured, the surface difference between the trunk lid and the vehicle body can be calculated. Correspondingly, by extracting the set of gap points of the areas to be measured, the gap between the trunk lid and the vehicle body can be calculated.

[0132] It should be noted that after the trunk lid is automatically assembled to the vehicle body using the above method, a manual inspection station can be set up to check the quality of the trunk lid assembly. Trunk lids that do not meet the assembly quality standards can then be adjusted.

[0133] Based on this, the present application also provides a vehicle trunk lid assembly control device. Figure 8 This is a schematic diagram of the composition structure of the vehicle trunk lid assembly control device provided in the embodiments of this application, as shown below. Figure 8 As shown, the control device 800 includes a first acquisition module 801, a second acquisition module 802, and a first adjustment module 803, wherein:

[0134] The first acquisition module 801 is used to acquire the reference position information of different parts of the test trunk lid relative to the vehicle body after the test trunk lid is installed on the vehicle body and adjusted to the reference position.

[0135] The second acquisition module 802 is used to acquire, during the process of assembling the current trunk lid to the vehicle body, the actual position information of different parts of the current trunk lid corresponding to the reference position information relative to the vehicle body.

[0136] The first adjustment module 803 is used to adjust the current position of the trunk lid relative to the vehicle body so that the deviation between the actual position information and the reference position information meets the preset conditions.

[0137] In some embodiments, the first adjustment module 803 is further configured to adjust the current position of the trunk lid relative to the vehicle body, such that the deviation between the first actual surface difference and the first reference surface difference is less than or equal to a first preset threshold, the deviation between the second actual surface difference and the second reference surface difference is less than or equal to a second preset threshold, the deviation between the third actual surface difference and the third reference surface difference is less than or equal to a third preset threshold, and the deviation between the average of the fifth actual surface difference and the sixth actual surface difference and the average of the fifth reference surface difference and the sixth reference surface difference is less than or equal to a fourth preset threshold.

[0138] In some embodiments, the device further includes a third acquisition module and a second adjustment module. The third acquisition module is used to acquire a first actual gap and a second actual gap between the left and right ends of the rear end of the current trunk lid along the vehicle's length direction and the vehicle body. The second adjustment module is used to adjust the position of the current trunk lid relative to the vehicle body so that the deviation between the first actual gap and the second actual gap is less than or equal to a fifth preset threshold.

[0139] In some embodiments, the device further includes a fourth acquisition module and a third adjustment module. The fourth acquisition module acquires reference position information of the test trunk lid relative to the hinge after it has been installed on the vehicle body and adjusted to a reference position. The third adjustment module adjusts the current position information of the trunk lid relative to the hinge so that the deviation between the current position information and the reference position information meets a preset range.
