[0057] In order to make the objectives, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the present application will be described in detail below with reference to the drawings. Obviously, the described embodiments are only some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without any creative effort shall fall within the protection scope of the present application.

[0058] In order to facilitate the understanding of the embodiments, the embodiments of the present application will be described in detail below.

[0059] Embodiment one:

[0060] Figure 1The processing method flowchart of the angle-dependent friction sliding in the folder is provided for the first embodiment of the present application.

[0061] Referring to Figure 1 The method comprises the following steps:

[0062] In step S101, attribute information of a target device is acquired, and a three-dimensional CAE model is constructed according to the attribute information of the target device.

[0063] Specifically, a three-dimensional CAE (computer aided engineering) model is established according to the shape structure, material information and weight information of the target device (such as a folder with a support), and the center of gravity position and total mass of the three-dimensional CAE model are accurately configured; the center of gravity position and mass of the three-dimensional CAE model are consistent with the real device. The shape structure of the target device is the outer surface shape surface of the target device, which can express the shape characteristics of the target device. Because the unfolding angle is different, the center of gravity position is different.

[0064] Because the three-dimensional CAE model is constructed according to the shape structure of the target device during modeling, the internal structure of the target device is not investigated, the inside of the three-dimensional CAE model is filled with entities, and the mass and center of gravity of the target device can be obtained according to the material density. If there is a deviation from the target value, the mass is controlled by adjusting the density, and then the center of gravity position is adjusted by adding a concentrated mass in a local position, so that the mass and center of gravity of the target device both reach the target value.

[0065] In step S102, a contact area between the target device and the support surface is defined in the three-dimensional CAE model, and a constraint condition and a gravity loading condition are applied.

[0066] Specifically, the force transmission between the contact surfaces can be realized by defining a contact pair at the contact surface and then defining corresponding friction coefficients for the mutually contacting pairs. By applying the constraint condition and the gravity loading condition, the boundary conditions of the three-dimensional CAE model are consistent with the real state, and then analysis and calculation can be performed to obtain the friction resistance under the first inclination angle. By adjusting the inclination angle in the inclination angle range of the target device, a series of analysis results can be obtained, so as to obtain the friction resistance data under a series of inclination angles.

[0067] In step S103, the reaction force between the contact surface of the target device and the support is calculated based on the constraint condition and the gravity loading condition through the finite element steady-state statics module of the structure analysis software.

[0068] In step S104, the condition under which the target device does not slide is obtained according to the reaction force and the Coulomb friction law.

[0069] Step S105, judging whether the contact surface friction coefficient meets the condition that the target device does not slide; if yes, executing step S106; if no, executing step S107;

[0070] Step S106, no relative sliding occurs between the target device and the support contact surface;

[0071] Step S107, relative sliding occurs between the target device and the support contact surface, and the friction structure design is optimized or the reverse support structure is added;

[0072] Wherein, the constraint condition is to limit the displacement of the target device in the normal direction of the support surface (simulate the contact surface constraint), and the gravity loading condition is the first inclination angle (such as 0° to 90°) actually used by the target device, and 1 times gravity is applied in the vertical direction. The gravity is the gravity acceleration g, so G=mg. Because there is mass on each grid element in the three-dimensional CAE model.

[0073] Specifically, if the condition that the target device does not slide is met, it means that the resistance is sufficient; if the condition that the target device does not slide is not met, it means that the resistance is not sufficient, and by increasing the friction coefficient of the contact surface, the analysis result is obtained by further analysis and calculation.

[0074] If it still cannot be realized by increasing the friction coefficient of the contact surface, the friction structure design can be optimized (such as adjusting the material, adding texture or modularizing the resistance component), so that no relative sliding occurs between the target device and the support contact surface; wherein, the texture is increased, and the contact surface is increased after being pressed. If the simple adjustment of the shape structure still cannot meet the requirement, then the reverse support structure needs to be added.

[0075] The application quantifies the support reaction force requirement under different inclination angles through finite element analysis, replaces the traditional experience design, and improves the precision and efficiency; the friction component that can be replaced or adjusted with the inclination angle (such as a stepped rubber pad and a magnetic sliding block) is proposed to enhance the universality of the device.

[0076] Further, the attribute information of the target device includes shape structure, material information and weight information, and step S101 includes the following steps:

[0077] Step S201, obtaining a device model of the target device according to the shape structure;

[0078] Step S202, discretizing the outer surface of the device model to obtain a processed device model;

[0079] Step S203, adding the material information and the weight information to the device model to generate a three-dimensional CAE model.

[0080] Further, the method further includes the following steps:

[0081] Step S301, a plurality of second inclination angles are obtained in the inclination angle range of the target device with a set angle as a step size; wherein the step size can be 5°;

[0082] Step S302, the support reaction force corresponding to each second inclination angle is calculated;

[0083] Step S303, a mapping relationship table is generated according to the support reaction force corresponding to each second inclination angle; wherein the mapping relationship table is used to represent the corresponding relationship between the inclination angle and the support reaction force;

[0084] Step S304, a design scheme meeting all inclination angle requirements is identified according to the mapping relationship table;

[0085] Step S305, the design scheme meeting all inclination angle requirements is simulated and verified, so as to obtain a scheme meeting the conditions.

[0086] Specifically, a plurality of second inclination angles (for example, 10°, 15°, 20°, etc.) are obtained in the inclination angle range of the target device with a set angle as a step size; steps S102 to S104 are repeated; the corresponding support reaction force can be obtained for each second inclination angle, and a support structure scheme meeting the non-sliding requirement can be obtained. According to the same method, the corresponding scheme for all angles can be obtained. According to the inclination angle-support reaction force mapping relationship table, a design scheme meeting all inclination angle requirements can be identified. The design scheme meeting all inclination angle requirements is simulated and verified, so as to obtain a scheme meeting the conditions. The present application covers the full range of use angles with a set angle as a step size, establishes a systematic design database, and supports parameterized configuration of a modular resistance structure.

[0087] Finally, according to the simulation data, a modular friction assembly (such as a replaceable rubber pad, a spring damper or a magnetic adsorption module) that can be adjusted with the inclination angle is designed, so as to ensure that the adaptive friction resistance is provided under different inclination angles.

[0088] Further, the support reaction force includes a horizontal direction support reaction force and a vertical direction support reaction force, and the condition that the target device does not slide is:

[0089] (1)

[0090] wherein μ is a friction coefficient of a contact surface, is the horizontal direction support reaction force, is the vertical direction support reaction force. is the minimum resistance required to prevent sliding.

[0091] The present application takes the horizontal direction support reaction force as the core index of the friction resistance design, so as to realize scientific and visual design optimization.

[0092] Further, the material information includes material name, material density, elastic modulus and Poisson's ratio, and the weight information includes mass and barycenter position of the target device in different unfolding states.

[0093] The following takes a folder with a notebook computer support as an example to describe the implementation process of the present application:

[0094] Referring to Figure 2 , Figure 3 and Figure 4 , a three-dimensional CAE model of the folder support is established, and the weight thereof is set to 1.5 kg, and the barycenter is located at the geometric center of the support.

[0095] Inclination angle analysis: the support reaction force is calculated at 15°, 30°, 45° and 60° inclination angles, respectively, and it is found that the horizontal direction support reaction force is the largest at 45° (wherein, Fx is the horizontal direction support reaction force, Fy is the vertical direction support reaction force, and θ is the inclination angle). ).

[0096] Structural optimization: a detachable friction plate is designed at the bottom of the support, a silica gel pad with μ=0.3 is used at low inclination angles (15°-30°), and a textured rubber pad with μ=0.5 is used at high inclination angles (45°-60°). At the same time, a reverse inclined surface is added to provide a reverse support force to ensure that no slip occurs.

[0097] Verification effect: through physical testing verification, the optimized support has no slip at any angle, and no redundant reinforcing structure is needed.

[0098] The folder of the present application can be designed in various forms according to actual needs, for example, functional components such as storage pockets and pen slots are arranged on the folder main body to further improve the practicality of the folder. At the same time, the material and shape of the rubber block can also be adjusted according to the actual use situation to achieve the best friction effect.
