Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a design method, device, electronic device, and medium for a gas spring for a vehicle tailgate. Background Art

[0002] In automobile design, gas springs are widely used to support and assist the opening and closing of car tailgates. The gas spring layout, calculation and verification methods in related technologies usually rely on traditional professional calculation software.

[0003] However, traditional professional calculation software limits the ability of relevant technical personnel to directly design, verify and analyze gas springs on the platform. At the same time, since the torque direction provided by gas springs in different working conditions (such as compression and extension) is different, the calculation complexity is increased and urgently needs to be solved. Summary of the Invention

[0004] The present application provides a method, device, electronic device and medium for designing a gas spring for a vehicle tailgate, in order to solve the problems that the calculation software of the related technology cannot directly design, verify and analyze the gas spring, and the calculation complexity is increased because the torque direction provided by the gas spring varies under different working conditions.

[0005] A first embodiment of the present application provides a method for designing a gas spring for a vehicle tailgate, comprising the following steps:

[0007] Based on the initial design strategy of the gas spring, a target angle of the vehicle tailgate is obtained, and based on the target angle, control output parameters of the gas spring under various temperature conditions are calculated, and the calculated results are recorded to generate an output parameter data set under each temperature condition;

[0008] Determine whether the output parameter data set satisfies preset gas spring design conditions. If the output parameter data set does not satisfy the preset gas spring design conditions, generate an alarm prompt to remind the user to re-enter the target angle of the vehicle tailgate until the output parameter data set satisfies the preset gas spring design conditions, thereby obtaining a final design strategy for the gas spring.

[0009] According to one embodiment of the present application, obtaining the gas spring input data of the user and determining the initial design strategy of the gas spring based on the gas spring input data includes:

[0010] Obtain the user-inputted surface of the gas spring body hinge point, the opening and closing system input parameter set, the gas spring input parameter set, and the system calculation control parameter set;

[0011] The gas spring body hinge point is calculated based on the surface where the gas spring body hinge point is located, the opening and closing system input parameter set, the gas spring input parameter set and the system calculation control parameter set, and the initial design strategy of the gas spring is determined based on the gas spring body hinge point.

[0012] According to one embodiment of the present application, the initial design strategy of the gas spring is used to obtain a target angle of the vehicle tailgate, and the control output parameters of the gas spring under various temperature conditions are calculated based on the target angle, including:

[0013] Based on the target angle of the vehicle tailgate, the first instantaneous closing force, the first full-range maximum closing force, the first instantaneous door opening force and the first full-range maximum door opening force of the gas spring under high-temperature conditions are calculated; the second instantaneous door closing force, the second full-range maximum closing force, the second instantaneous door opening force and the second full-range maximum door opening force of the gas spring under normal-temperature conditions; the third instantaneous door closing force, the third full-range maximum closing force, the third instantaneous door opening force and the third full-range maximum door opening force of the gas spring under low-temperature conditions, and the maximum compression of the gas spring during the opening and closing process are calculated.

[0014] According to one embodiment of the present application, the determining whether the output parameter data set satisfies a preset gas spring design condition, and generating an alarm prompt if the output parameter data set does not satisfy the preset gas spring design condition, includes:

[0015] Determining whether the target angle is greater than a preset angle threshold, or whether a first instantaneous closing force and a first full-range maximum closing force of the gas spring under high-temperature conditions are greater than a first preset closing force threshold, or whether a third instantaneous closing force and a third full-range maximum closing force of the gas spring under low-temperature conditions are less than a second preset closing force threshold, or whether a maximum compression of the gas spring during the opening and closing process is greater than a preset compression threshold;

[0016] If the target angle is greater than the preset angle threshold, or the first instantaneous closing force and the first full-range maximum closing force of the gas spring under the high-temperature working condition are greater than the first preset closing force threshold, or the third instantaneous closing force and the third full-range maximum closing force of the gas spring under the low-temperature working condition are less than the second preset closing force threshold, or the maximum compression of the gas spring during the opening and closing process is greater than the preset compression threshold, it is determined that the output parameter data set does not meet the preset gas spring design conditions.

[0017] According to one embodiment of the present application, the maximum compression of the gas spring during the opening and closing process includes:

[0018] Calculating the instantaneous length of the gas spring corresponding to the target angle based on the target angle;

[0019] The maximum compression amount of the gas spring during the opening and closing process is obtained according to the natural state length of the gas spring and the instantaneous length of the gas spring in the gas spring input parameter set.

[0020] According to an embodiment of the present invention, a gas spring design method for a vehicle tailgate is provided. The gas spring's geometric elements and target parameters are obtained to determine an initial design strategy for the gas spring. A target angle for the vehicle tailgate is then obtained. Based on the target angle, control output parameters for the gas spring under various temperature conditions are calculated and recorded, generating an output parameter dataset for each temperature condition. If the output parameter dataset does not meet the preset gas spring design conditions, an alarm is generated to prompt the user to re-enter the target angle for the vehicle tailgate. This process continues until the output parameter dataset meets the preset gas spring design conditions, thereby obtaining a final gas spring design strategy. This method addresses the issues of related art computing software being unable to directly design, verify, and analyze gas springs, and increasing computational complexity due to the varying torque directions provided by gas springs under different operating conditions.

The software instantly adjusts the gas spring layout based on the input geometric elements and parameters, outputs control parameters, completes gas spring selection, and obtains a final gas spring layout through verification analysis, thereby improving the adaptability and reliability of gas spring design.

[0025] According to one embodiment of the present application, the acquisition module is specifically configured to:

[0048] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0049] The following describes, with reference to the accompanying drawings, a gas spring design method, device, electronic device, and medium for a vehicle tailgate according to an embodiment of the present application. Given that the computational software of the related art mentioned in the background art cannot directly design, verify, or analyze gas springs, and that the torque direction provided by the gas spring varies under different operating conditions, thereby increasing computational complexity, the present application provides a gas spring design method for a vehicle tailgate. In this method, geometric elements and target parameters of the gas spring are obtained to determine an initial design strategy for the gas spring. A target angle for the vehicle tailgate is then obtained, and control output parameters of the gas spring under various temperature conditions are calculated and recorded based on the target angle. An output parameter data set is generated for each temperature condition, and an alarm is generated if the output parameter data set does not meet the preset gas spring design conditions to remind the user to re-enter the target angle for the vehicle tailgate. This process continues until the output parameter data set meets the preset gas spring design conditions, thereby obtaining a final design strategy for the gas spring. As a result, the problems that the calculation software of the relevant technology cannot directly design, verify and analyze the gas spring, and the calculation complexity is increased due to the different directions of the torque provided by the gas spring under different working conditions are solved. The present application is based on the development of a three-dimensional design software with functions such as parametric design, management of relationships and rules between parameters, optimization design, parameter value checking and conditional response. The layout plan of the gas spring is adjusted in real time according to the input geometric elements and parameters, the control parameters are output and the gas spring selection is completed, and the final gas spring layout plan is obtained through verification analysis, thereby improving the adaptability and reliability of the gas spring design.

[0050] Specifically, before introducing the embodiments of the present application, the problems existing in the related art are first introduced. (1) The software used for the arrangement, verification, stroke and calculation of the opening and closing force of the gas spring in the related art is all traditional professional calculation software, which makes it impossible for the relevant technical personnel who use three-dimensional design software to design the opening and closing parts to directly perform systematic stroke verification and opening and closing force calculation on the preliminary gas spring arrangement scheme; (2) Due to the specific rotation axis position of the opening and closing system, the position of the gas spring hinge point is different in the entire opening and closing stroke of the opening and closing system. The direction of the torque provided by the gas spring is different. Therefore, under the conditions of a specific gas spring, a specific temperature and a specific arrangement, it is difficult to use a function to express the torque of the gas spring on the rotation axis during the compression process and the torque of the gas spring on the rotation axis during the extension process; (3) The force value at the same position of the gas spring during the extension process and the compression process is different, that is, the force value and displacement curve of the gas spring during the compression process are different from the force value and displacement curve of the gas spring during the extension process. However, in order to improve the scope of application of the three-dimensional design software, it is necessary to have the adaptability beyond the design range of the angle of the opening and closing parts. That is, in the single opening stroke of the opening and closing parts, the gas spring may undergo compression and extension transformations, which makes it difficult to implement a specific gas spring, a specific opening and closing shaft, and a gas spring hinge point arrangement scheme. That is, in the opening or closing to single-direction stroke, it is difficult to use a function to express the torque of the gas spring; (4) In the gas spring arrangement scheme of the related art, the angle (i.e., geometric dead angle) between the gas spring in the closed state and several dead point lines of the door system (the line connecting the center of rotation of the door and the hinge point on the gas spring in the calculation surface), and the distance between the hinge point on the gas spring and the door axis have a great influence on the calculation results, and thus the positions of the upper and lower hinge points of the gas spring that affect the above parameters involve the X, Y, and Z coordinates of the lower hinge point of the gas spring, the length of the gas spring in the natural state, and the distance between the upper hinge point of the gas spring and the vehicle body. Among them, the distance between the upper hinge point of the gas spring and the vehicle body is generally directly controlled to the required size. However, in the process of adjusting the above parameters, obtaining the required geometric dead angle and the distance between the upper hinge point and the door axis involves relatively complex calculations, making this process more difficult to implement.

[0051] Therefore, the embodiment of the present application is based on the development of a three-dimensional design software, which has functions such as parametric design, management of relationships and rules between parameters, optimization design, parameter value checking and conditional response, and the three-dimensional design software can directly assemble based on the surrounding environment parts, and can instantly adjust the layout of the gas spring according to the input geometric elements and parameters, output control parameters and complete the gas spring selection, and obtain the final gas spring layout plan through verification analysis, thereby improving the adaptability and reliability of the gas spring design, and making the visualization effect better.

[0052] Specifically, Figure 1 A flow chart of a method for designing a gas spring for a vehicle tailgate provided in an embodiment of the present application.

[0053] like Figure 1 As shown, the gas spring design method for the vehicle tailgate includes the following steps:

[0054] In step S101 , the geometric elements and target parameters of the gas spring input by the user are obtained, and an initial design strategy of the gas spring is determined based on the geometric elements and target parameters of the gas spring.

[0055] According to one embodiment of the present application, the user's gas spring input data is obtained, and the initial design strategy of the gas spring is determined based on the gas spring input data, including: obtaining the surface where the gas spring body hinge point is located, the opening and closing system input parameter set, the gas spring input parameter set and the system calculation control parameter set input by the user; calculating the gas spring body hinge point based on the surface where the gas spring body hinge point is located, the opening and closing system input parameter set, the gas spring input parameter set and the system calculation control parameter set, and determining the initial design strategy of the gas spring based on the gas spring body hinge point.

[0056] Specifically, if Figure 2 As shown, the three-dimensional design software is mainly composed of the input geometric elements, process geometric elements, output geometric elements, target input parameters, process calculation parameters, output control parameters, specific formulas, rules, reactions, and inspection items of the gas spring. In the embodiment of the present application, first, the gas spring geometric elements and target parameters are input based on the user's usage requirements, wherein the gas spring geometric elements include the surface where the gas spring body hinge point is located, and the target parameters include the opening and closing system input parameter set, the gas spring input parameter set, and the system calculation control parameter set; secondly, after receiving the gas spring geometric elements and target parameters input by the user, the three-dimensional design software will calculate a point on the surface where the gas spring body hinge point is located, which is the gas spring body hinge point. After the gas spring body hinge point is calculated, the initial design strategy of the gas spring is determined.

[0057] Among them, the input parameter set of the opening and closing system mainly includes the flip angle of the back door in the opening state, the coordinates of the rotation axis point, the coordinates of the lower fulcrum of the gas spring cover in the closed state, the coordinates of the center of mass of the door part in the closed state, the hand-opening force arm, the hand-closing force arm, the Y-plane control distance of the fulcrum on the body of the gas spring, the X-direction control of the surface where the fulcrum is located on the body, and the angle of the surface where the fulcrum is located on the body; the input parameter set of the gas spring mainly includes the natural state length of the gas spring, the minimum force F1 in the extension direction of the gas spring at 20°C, the maximum force F2 in the extension direction of the gas spring at 20°C, the minimum force F3 in the compression direction of the gas spring at 20°C, the maximum force F4 in the compression direction of the gas spring at 20°C, The position of force measuring point XF1 (XF3), the position of force measuring point XF2 (XF4), the force value difference between the isotropic points of the gas spring at 20℃ and -30℃, the force value difference between the isotropic points of the gas spring at 50℃ and 20℃, and the standard stroke of the gas spring; the system calculation control parameter set mainly includes the instantaneous angle of the opening and closing process and the clearing of the cached parameter values; the output geometric elements mainly include the schematic line of the gas spring in the open state, the schematic line of the gas spring in the closed state, the schematic line of the trajectory of the gas spring door hinge point, the instantaneous schematic line of the gas spring, the center of gravity of the door in the closed state, the center of gravity of the door in the open state, the instantaneous point of the center of gravity of the door body, the instantaneous schematic line of the door body weight, the opening and closing component rotation axis, etc.

[0058] It should be noted that after entering the geometric elements and target parameters, the 3D design software will solve a point on the surface where the gas spring body hinge point is located, unless the distance between the surface where the gas spring body hinge point is located and the lower support point of the gas spring cover is greater than the length of the gas spring. At this time, the 3D design software cannot solve the gas spring body hinge point. Therefore, you can adjust the natural state length parameter of the gas spring in the target parameters of the gas spring input or adjust the input geometric element "surface where the gas spring body hinge point is located" so that the 3D design software can solve a point on the surface where the gas spring body hinge point is located.

[0059] In step S102, based on the initial design strategy of the gas spring, the target angle of the vehicle tailgate is obtained, and the control output parameters of the gas spring under various temperature conditions are calculated based on the target angle. The calculation results are recorded to generate an output parameter data set under each temperature condition.

[0060] According to one embodiment of the present application, based on the initial design strategy of the gas spring, the target angle of the vehicle's tailgate is obtained, and the control output parameters of the gas spring under various temperature conditions are calculated based on the target angle, including: calculating the first instantaneous closing force, the first full-range maximum closing force, the first instantaneous opening force and the first full-range maximum opening force of the gas spring under high-temperature conditions based on the target angle of the vehicle's tailgate, the second instantaneous closing force, the second full-range maximum closing force, the second instantaneous opening force and the second full-range maximum opening force of the gas spring under normal temperature conditions, the third instantaneous closing force, the third full-range maximum closing force, the third instantaneous opening force and the third full-range maximum opening force of the gas spring under low-temperature conditions, and the maximum compression of the gas spring during the opening and closing process.

[0061] According to one embodiment of the present application, the maximum compression of the gas spring during the opening and closing process includes: calculating the instantaneous length of the gas spring corresponding to the target angle based on the target angle; and obtaining the maximum compression of the gas spring during the opening and closing process according to the natural state length of the gas spring and the instantaneous length of the gas spring in the gas spring input parameter set.

[0062] Specifically, if Figure 2 and Figure 3 As shown, after obtaining the initial design strategy of the gas spring in the embodiment of the present application, the user can specify the target angle (i.e., the calculation angle) for further calculation and analysis. First, the user can Figure 3 Enter the target angle in the display box, and after receiving the target angle of the vehicle tailgate input by the user, calculate the control output parameters of the gas spring corresponding to various temperature conditions at the target angle based on the target angle. For example, based on the target angle, the first instantaneous closing force, the first full-range maximum closing force, the first instantaneous opening force and the first full-range maximum opening force under high temperature conditions (for example, 50℃ / 80℃) can be generated, the second instantaneous closing force, the second full-range maximum closing force, the second instantaneous opening force and the second full-range maximum opening force of the gas spring under normal temperature conditions (for example, 20℃), the third instantaneous closing force, the third full-range maximum closing force, the third instantaneous opening force and the third full-range maximum opening force of the gas spring under low temperature conditions (for example, -30℃) and the maximum compression of the gas spring during the opening and closing process corresponding to the target angle can be generated.

[0063] Among them, the high temperature working condition temperature value depends on the high temperature working condition temperature value provided by the gas spring, and the maximum compression amount of the gas spring during the opening and closing process is obtained according to the natural state length of the gas spring and the instantaneous length of the gas spring.

[0064] Furthermore, after calculating the control output parameters of the gas spring under various temperature conditions based on the target angle, the embodiment of the present application records the calculation results, that is, records the first instantaneous closing force, the first full-range maximum closing force, the first instantaneous opening force and the first full-range maximum opening force of the gas spring under high-temperature conditions, the second instantaneous closing force, the second full-range maximum closing force, the second instantaneous opening force and the second full-range maximum opening force of the gas spring under normal temperature conditions, the third instantaneous closing force, the third full-range maximum closing force, the third instantaneous opening force and the third full-range maximum opening force of the gas spring under low-temperature conditions, and the maximum compression of the gas spring during the opening and closing process, thereby generating an output parameter data set under each temperature condition.

[0065] In step S103, it is determined whether the output parameter data set meets the preset gas spring design conditions. If the output parameter data set does not meet the preset gas spring design conditions, an alarm prompt is generated to remind the user to re-enter the target angle of the vehicle tailgate until the output parameter data set meets the preset gas spring design conditions, thereby obtaining the final design strategy for the gas spring.

[0066] According to one embodiment of the present application, whether the output parameter data set meets the preset gas spring design conditions is judged. If the output parameter data set does not meet the preset gas spring design conditions, an alarm prompt is generated, including: judging whether the target angle is greater than the preset angle threshold, or whether the first instantaneous closing force and the first full-range maximum closing force of the gas spring under high temperature conditions are greater than the first preset closing force threshold, or whether the third instantaneous closing force and the third full-range maximum closing force of the gas spring under low temperature conditions are less than the second preset closing force threshold, or whether the maximum compression of the gas spring during the opening and closing process is greater than the preset compression threshold; if the target angle is greater than the preset angle threshold, or the first instantaneous closing force and the first full-range maximum closing force of the gas spring under high temperature conditions are greater than the first preset closing force threshold, or the third instantaneous closing force and the third full-range maximum closing force of the gas spring under low temperature conditions are less than the second preset closing force threshold, or the maximum compression of the gas spring during the opening and closing process is greater than the preset compression threshold, then it is determined that the output parameter data set does not meet the preset gas spring design conditions.

[0067] Among them, the preset gas spring design conditions, preset angle threshold, first preset closing force threshold, second preset closing force threshold and preset compression threshold can all be set by technical personnel in this field according to the actual needs of the test, or can be obtained through computer simulation, and are not specifically limited here.

[0068] Specifically, after obtaining the output parameter data set under various temperature conditions, ie, the control output parameters, the present application needs to further evaluate the control output parameters to detect the rationality of the calculation of the control output parameters.

[0069] Specifically, the embodiment of the present application needs to determine whether the target angle input by the user is greater than a preset angle threshold, or whether the first instantaneous closing force and the first full-range maximum closing force of the gas spring under high temperature conditions calculated according to the target angle are greater than the first preset closing force threshold, or whether the third instantaneous closing force and the third full-range maximum closing force of the gas spring under low temperature conditions calculated according to the target angle are less than the second preset closing force threshold, or whether the maximum compression of the gas spring during the opening and closing process calculated according to the target angle is greater than the preset compression threshold; if the target angle is greater than the preset angle threshold, or the first instantaneous closing force and the first full-range maximum closing force of the gas spring under high temperature conditions are greater than the first preset closing force threshold, Or the third instantaneous closing force and the third full-range maximum closing force of the gas spring under low-temperature conditions are less than the second preset closing force threshold, or the maximum compression of the gas spring during the opening and closing process is greater than the preset compression threshold, then it means that the calculated control output parameters do not meet the design requirements of the gas spring, that is, it is determined that the output parameter data set does not meet the preset gas spring design conditions. At this time, an alarm prompt is generated, such as an acoustic reminder device such as a vehicle horn or an optical reminder device such as a vehicle display screen, to remind the user to re-enter the target angle, and recalculate based on the newly input target angle, and output new control output parameters until the output parameter data set meets the preset gas spring design conditions, thereby obtaining the final design strategy of the gas spring.

[0070] Furthermore, after obtaining a final design strategy for a gas spring, the user can choose to clear the cache, so that the design strategy for the corresponding gas spring can be calculated based on the new target angle until the calculation of all required target angles is completed.

[0071] Furthermore, in order to solve the above-mentioned problem of difficulty in using a function to express the torque of the gas spring on the rotating shaft during compression and using a function to express the torque of the gas spring on the rotating shaft during elongation under specific gas spring, specific temperature and specific arrangement conditions, the embodiment of the present application introduces a parameter (i.e., gas spring torque direction parameter) based on the three-dimensional design software. The gas spring torque direction parameter detects and indicates the direction of the gas spring torque. The gas spring torque direction parameter is related to the two hinge points of the gas spring and the position of the opening and closing system rotating shaft. The direction of the gas spring force on the opening and closing system rotating shaft can be automatically determined. The solution of the gas spring torque direction is 1 or -1. After the introduction of the gas spring torque direction parameter, under specific temperature, specific arrangement and specific gas spring conditions, the following is satisfied:

[0072] The torque of the compressed gas spring force on the rotating shaft = compressed gas spring force * gas spring force arm * gas spring torque direction parameter;

[0073] The torque of the extended gas spring force on the rotating shaft = extended gas spring force * gas spring force arm * gas spring torque direction parameter;

[0074] The compression gas spring force, extension gas spring force, gas spring force arm, and gas spring torque direction parameters all change with the angle of the opening and closing member.

[0075] Furthermore, in order to solve the problem that the gas spring may undergo compression and extension changes during the single opening stroke of the opening and closing member, and thus makes it difficult to implement a specific gas spring, a specific opening and closing shaft, and a gas spring hinge point arrangement scheme, the embodiment of the present application introduces four parameters into the three-dimensional design software of the embodiment of the present application, mainly including a closing compression indication parameter, a closing extension indication parameter, an opening compression indication parameter, and an opening extension indication parameter. The above four parameters respectively detect and indicate the closing compression, closing extension, opening compression, and opening extension of the gas spring, and their solutions are all 1 or 0. After introducing the above four parameters, under specific temperature, specific arrangement conditions, and specific gas spring working conditions, the calculation method is as follows:

[0076] Gas spring torque during closing process = closing compression indication parameter * compression gas spring force torque on the rotating shaft + closing extension indication parameter * extension gas spring force torque on the rotating shaft;

[0077] Gas spring torque during opening process = opening compression indication parameter * compression gas spring force torque on the rotating shaft + opening extension indication parameter * extension gas spring force torque on the rotating shaft.

[0078] Furthermore, if Figure 4 As shown, the embodiment of the present application is to solve the above-mentioned problem that the angles between the gas spring in the closed state and several dead point lines of the door system, the distance between the upper hinge point of the gas spring and the door axis have a great influence on the calculation results, and thus the positions of the upper and lower hinge points of the gas spring that affect the above-mentioned parameters involve the X, Y, and Z coordinates of the lower hinge point of the gas spring, the length of the gas spring in the natural state, and the distance between the upper hinge point of the gas spring and the vehicle body, which involves more complex calculations, making this process difficult to implement. The embodiment of the present application introduces the parameters of the angle between the axis of the gas spring in the closed state and the geometric dead point line, and the parameters of the distance between the upper hinge point of the gas spring and the door axis based on the three-dimensional design software, and then introduces the optimization design task. When the calculation results of the initial design strategy do not meet the conditions ( For example, if the door system has no self-locking stroke due to a small geometric dead angle, or the gas spring force value is too large due to a small distance between the upper hinge point and the door axis, the user can set the target geometric dead angle through the optimization design task "Optimize the angle between the closed state gas spring and the geometric dead point line" to find the corresponding X, Y, and Z coordinates of the lower hinge point of the gas spring. If the optimization result has no solution, find the variable to increase the constraint parameters of the line where the upper hinge point of the gas spring is located. If there is still no solution after adding the constraint parameters of the line where the upper hinge point of the gas spring is located, add the variable gas spring natural state length. Therefore, the user can set the target distance through the optimization design task "Optimize the size of the upper support point from the door axis" to find the corresponding X, Y, and Z coordinates of the lower hinge point of the gas spring.

[0079] Therefore, when designing the opening and closing part assist mechanism, the embodiment of the present application can simplify the process of calculating the actual compression stroke of the gas spring, the opening and closing force calculation process, and the adjustment process of the gas spring arrangement scheme for technical personnel in this field for different gas spring arrangement schemes, thereby improving the adaptability and reliability of the gas spring design.

[0080] According to an embodiment of the present invention, a gas spring design method for a vehicle tailgate is provided. The gas spring's geometric elements and target parameters are obtained to determine an initial design strategy for the gas spring. A target angle for the vehicle tailgate is then obtained. Based on the target angle, control output parameters for the gas spring under various temperature conditions are calculated and recorded, generating an output parameter dataset for each temperature condition. If the output parameter dataset does not meet the preset gas spring design conditions, an alarm is generated to prompt the user to re-enter the target angle for the vehicle tailgate. This process continues until the output parameter dataset meets the preset gas spring design conditions, thereby obtaining a final gas spring design strategy. This method addresses the issues of related art computing software being unable to directly design, verify, and analyze gas springs, and increasing computational complexity due to the varying torque directions provided by gas springs under different operating conditions. The present invention is based on the development of three-dimensional design software with functions such as parametric design, parameter relationship management and rules, optimization design, parameter value checking, and conditional response. The software instantly adjusts the gas spring layout based on the input geometric elements and parameters, outputs control parameters, completes gas spring selection, and obtains a final gas spring layout through verification analysis, thereby improving the adaptability and reliability of gas spring design.

[0081] Next, a gas spring design device for a vehicle tailgate according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0082] Figure 5 It is a block diagram of a gas spring design device for a vehicle tailgate according to an embodiment of the present application.

[0083] like Figure 5 As shown, the gas spring design device 10 for a vehicle tailgate includes: an acquisition module 100 , a calculation module 200 and an adjustment module 300 .

[0084] The acquisition module 100 is used to obtain the geometric elements and target parameters of the gas spring input by the user, and determine the initial design strategy of the gas spring based on the geometric elements and target parameters of the gas spring;

[0085] The calculation module 200 is used to obtain a target angle of the vehicle tailgate based on the initial design strategy of the gas spring, calculate the control output parameters of the gas spring under various temperature conditions based on the target angle, and record the calculation results to generate an output parameter data set under each temperature condition;

[0086] The adjustment module 300 is used to determine whether the output parameter data set meets the preset gas spring design conditions. If the output parameter data set does not meet the preset gas spring design conditions, an alarm prompt is generated to remind the user to re-enter the target angle of the vehicle tailgate until the output parameter data set meets the preset gas spring design conditions, thereby obtaining the final design strategy for the gas spring.

[0087] According to one embodiment of the present application, the acquisition module 100 is specifically configured to:

[0088] Obtain the user-inputted surface of the gas spring body hinge point, the opening and closing system input parameter set, the gas spring input parameter set, and the system calculation control parameter set;

[0089] The hinge point of the gas spring body is calculated based on the surface where the gas spring body hinge point is located, the opening and closing system input parameter set, the gas spring input parameter set and the system calculation control parameter set. The initial design strategy of the gas spring is determined based on the hinge point of the gas spring body.

[0090] According to one embodiment of the present application, the computing module 200 is specifically configured to:

[0091] Based on the target angle of the vehicle's tailgate, calculate the first instantaneous closing force, first full-range maximum closing force, first instantaneous door opening force and first full-range maximum door opening force of the gas spring under high-temperature conditions, the second instantaneous door closing force, second full-range maximum door closing force, second instantaneous door opening force and second full-range maximum door opening force of the gas spring under normal-temperature conditions, the third instantaneous door closing force, third full-range maximum door closing force, third instantaneous door opening force and third full-range maximum door opening force of the gas spring under low-temperature conditions, and the maximum compression of the gas spring during the opening and closing process.

[0092] According to one embodiment of the present application, the adjustment module 300 is specifically configured to:

[0093] Determine whether the target angle is greater than a preset angle threshold, or whether the first instantaneous closing force and the first full-range maximum closing force of the gas spring under high temperature conditions are greater than a first preset closing force threshold, or whether the third instantaneous closing force and the third full-range maximum closing force of the gas spring under low temperature conditions are less than a second preset closing force threshold, or whether the maximum compression of the gas spring during the opening and closing process is greater than a preset compression threshold;

[0094] If the target angle is greater than the preset angle threshold, or the first instantaneous closing force and the first full-range maximum closing force of the gas spring under high-temperature conditions are greater than the first preset closing force threshold, or the third instantaneous closing force and the third full-range maximum closing force of the gas spring under low-temperature conditions are less than the second preset closing force threshold, or the maximum compression of the gas spring during the opening and closing process is greater than the preset compression threshold, then it is determined that the output parameter data set does not meet the preset gas spring design conditions.

[0095] According to one embodiment of the present application, the computing module 200 is specifically configured to:

[0096] Calculate the instantaneous length of the gas spring corresponding to the target angle based on the target angle;

[0097] The maximum compression amount of the gas spring during the opening and closing process is obtained according to the natural state length of the gas spring and the instantaneous length of the gas spring in the gas spring input parameter set.

[0098] According to an embodiment of the present invention, a gas spring design device for a vehicle tailgate obtains gas spring geometric elements and target parameters to determine an initial design strategy for the gas spring. A target angle for the vehicle tailgate is then obtained. Based on the target angle, control output parameters for the gas spring under various temperature conditions are calculated and recorded, generating an output parameter dataset for each temperature condition. If the output parameter dataset does not meet the preset gas spring design conditions, an alarm is generated to prompt the user to re-enter the target angle for the vehicle tailgate until the output parameter dataset meets the preset gas spring design conditions, thereby obtaining a final gas spring design strategy. This solves the problem that related art calculation software cannot directly design, verify, and analyze gas springs, and that the calculation complexity increases due to the different torque directions provided by gas springs under different operating conditions. The present invention is based on the development of three-dimensional design software with functions such as parametric design, parameter relationship management and rules, optimization design, parameter value checking, and conditional response. The software instantly adjusts the gas spring layout based on the input geometric elements and parameters, outputs control parameters, completes gas spring selection, and obtains the final gas spring layout through verification analysis, thereby improving the adaptability and reliability of gas spring design.
