Description

Technical Field

[0001] The present invention relates to the field of vehicles, and further to a window edge wrapping structural member, a window, and a manufacturing method of the window edge wrapping structural member, and particularly to a window edge wrapping structural member containing shape memory alloy therein, a window, and a manufacturing method of the window edge wrapping structural member. Background Art

[0002] With the continuous development of the automobile manufacturing industry, consumers and manufacturers have higher and higher requirements for the delicate perception of the automobile styling. Among them, as Figure 1 , Figure 2 shown, achieving a good adaptation effect (such as fitting or a gap or a gradual gap that meets the adaptation requirements) between the tongue of the window edge wrapping structure 100 and the vehicle environmental part 200 is one of the components for enhancing the delicate perception of the automobile styling.

[0003] Considering from the aspects of manufacturing product tolerances, installation tolerances, sheet metal tolerances, etc., in order to achieve a good fit between the tongue of the window edge wrapping structure 100 and the vehicle environmental part 200 or a gap that meets the adaptation requirements, the pre-deformation effect needs to be considered during the manufacturing of the window edge wrapping structure 100 to absorb the above tolerances. Usually, a pre-deformation amount of 0 - 15 mm is reserved.

[0004] However, at present, due to the differences in vehicle styling, the vehicle environmental part 200 cannot be standardized, resulting in a variety of different types of edge wrapping structures designed according to the cooperation conditions of the vehicle environmental part 200, with large differences and unable to be standardized; the differences in the edge wrapping structures (such as: the size fluctuation range of the edge wrapping or the insert is 0 - 5 mm) will cause the sizes of the products (such as: the size fluctuation range of the glass is 0.5 mm - 3.0 mm) to have a large range of fluctuations, and the pre-deformation amount of each structural member can only be determined by experience and review; in addition, due to the differences in sheet metal materials and manufacturing capabilities of each manufacturer, the controllable size range of the sheet metal and other vehicle environmental parts 200 is between 0 mm - 2 mm. Due to the above reasons, it is very difficult for the initial window edge wrapping structure 100 to reach an ideal adaptation state with the vehicle environmental part 200 once after being installed on the vehicle, and multiple rounds of mutual adjustment and matching are required to achieve a good adaptation effect.

[0005] Therefore, in the initial design of the window edge wrapping structure 100, it is usually necessary to divide it into the theoretical installation effect data and the development data of the pre-deformation amount of the window edge wrapping structure 100. The data is numerous, the workload is large, and it is necessary to re-evaluate and design the pre-deformation amount and development data according to the actual effect after the product is installed in the vehicle (whether good fitting is achieved or the gap meets the adaptation requirements). Since it is impossible to design and form in one go in most cases, it can only be achieved through multiple "trial and error" and modifications in the early stage to achieve fitting or a gap that meets the adaptation requirements at corresponding positions (such as between the tongue of the window edge wrapping structure 100 and the vehicle environmental part 200). Therefore, it is necessary to modify the mold multiple times (such as milling, welding, or lowering the surface of the mold, or even replacing the mold core, etc.). This not only consumes a large amount of manpower and material resources, but also the time required during the modification process is uncertain, and the delivery time of the product cannot be controlled. In addition, during the long-term use of the existing window edge wrapping structure 100, it is prone to aging due to changes in environmental temperature, losing elasticity, deforming and generating gaps, and unable to achieve the preset installation effect in the vehicle.

[0006] In view of the above, a window edge wrapping structure part, a window, and a manufacturing method of the window edge wrapping structure part are provided to overcome the defects of the prior art. Summary of the Invention

[0025] Step S4: Cool the window edge wrapping structural part until the shape memory alloy part is in the low-temperature phase shape, so that the shape memory alloy part restores a preset deformation amount, and a window edge wrapping structural part in the vehicle-mounted shape is obtained.

[0026] In a preferred embodiment of the present invention, before the step S1, theoretical data of the window edge wrapping structural part is obtained, and a mold is developed according to the theoretical data; wherein, the theoretical data of the window edge wrapping structural part at least includes the theoretical data of the shape memory alloy part and the theoretical data of the edge wrapping part.

[0058] For a clearer understanding of the technical features, objectives, and effects of the present invention, the specific implementation manner of the present invention will now be described with reference to the accompanying drawings.

[0059] Implementation manner 1

[0060] As Figures 3 to 11 shown, the present invention provides a window edge - wrapping structural component, which includes an edge - wrapping component 1 and a shape - memory alloy component 2. The shape - memory alloy component 2 is disposed inside the edge - wrapping component 1. By presetting the deformation amount of the shape - memory alloy component 2, the shape - memory alloy component 2 can deform by the preset deformation amount between the high - temperature phase shape and the low - temperature phase shape. Furthermore, when the edge - wrapping component 1 is in a state of being cooperatively installed with the vehicle body environmental component 3, the edge - wrapping component 1 can be adapted to the vehicle body environmental component 3.

[0061] In the present invention Figures 3 to 5 is intended to indicate the deformations generated by the shape - memory alloy component 2 at the high - temperature phase shape and the low - temperature phase shape respectively. In actual situations, due to the deformation of the shape - memory alloy component 2, the edge - wrapping component 1 will also deform (that is: the positional relationship between the edge - wrapping component 1 and the vehicle body environmental component 3 changes), and the deformation of the edge - wrapping component 1 can be Figures 6 to 9 shown, in Figures 3 to 5 the deformation of the edge - wrapping component 1 is not shown.

[0062] Among them, the edge - wrapping component 1 being adapted to the vehicle body environmental component 3 means that the edge - wrapping component 1 and the vehicle body environmental component 3 meet the vehicle - loading requirements. This includes at least that the tongue 101 of the edge - wrapping component 1 fits with the vehicle body environmental component 3, and there is a gap that meets the adaptation requirements between the edge - wrapping component 1 and the vehicle body environmental component 3 (this gap can be a uniform gap or a gap with a gradually changing width, which is determined according to actual assembly requirements).

[0063] Furthermore, the vehicle body environmental component 3 can be, but is not limited to, components such as sheet - metal structures, sealing structures, or plastic structures on the vehicle body that need to be cooperatively installed with the edge - wrapping component 1.

[0064] In the present invention, a shape memory alloy member 2 is additionally provided inside the edge wrapping member 1, and the deformation amount of the shape memory alloy member 2 is preset. By virtue of the phase change characteristics of the shape memory alloy member 2 at different temperatures, the shape memory alloy member 2 can deform between the high-temperature phase shape and the low-temperature phase shape according to the preset deformation amount, so as to achieve the purpose of adapting the edge wrapping member 1 to the vehicle body environment member 3 in the installed state, thereby shortening the trial-and-error and modification time during the manufacturing process of the edge wrapping member 1, ensuring that the edge wrapping member 1 can meet the adaptation to the vehicle body environment member 3, and improving production efficiency and product quality.

[0065] In an alternative embodiment of the present invention, the shape memory alloy member 2 is preferably a two-way shape memory alloy. The two-way shape memory alloy can deform into a high-temperature phase shape after heating and return to a low-temperature phase shape after cooling. The low-temperature phase shape of the shape memory alloy member 2 is in a state adapted to the vehicle body environment member 3.

[0066] Specifically, the shape memory alloy member 2 is made of a shape memory alloy (SMA), which may be made of, but not limited to, an iron-based memory alloy. The shape memory alloy has characteristics such as shape memory effect, superelasticity, and high damping. It can sense temperature changes and convert thermal energy into mechanical energy, outputting force, displacement or storing and releasing energy. Since the shape memory alloy member 2 in the present invention is applied to the window edge wrapping structural member, and the conventional production environment temperature of the vehicle is lower than 130 °C, an iron-based memory alloy with a high-temperature phase change temperature between 100 °C and 130 °C and a low-temperature phase change temperature between 30 °C and 70 °C can be selected, so that the shape memory alloy member 2 can deform according to the preset deformation amount under the corresponding conditions of the high-temperature phase change temperature and the low-temperature phase change temperature.

[0067] In an alternative embodiment of the present invention, such as Figure 3 、 Figure 4 、 Figure 6 、 Figure 8As shown, the shape memory alloy member 2 includes a deformation section 201 and a support section 202. The deformation section 201 is designed to be shaped like the edge wrapping member 1 (i.e., they have the same bending trend and similar or the same bending arc). One end of the deformation section 201 is connected to the support section 202, and the other end of the deformation section 201 extends in a direction adapted to the vehicle body environmental member 3 (in this embodiment, the deformation section 201 extends towards the vehicle body environmental member 3). The edge wrapping member 1 corresponding to the support section 202 is connected to the window glass. The deformation section 201 is preset with a deformation amount adapted to the vehicle body environmental member 3, and the edge wrapping member 1 corresponding to the deformation section 201 is inclined in a direction adapted to the vehicle body environmental member 3 (in this embodiment, the edge wrapping member 1 corresponding to the deformation section 201 is inclined towards the vehicle body environmental member 3), so that the edge wrapping member 1 fits with the vehicle body environmental member 3, or there is a gap meeting the adaptation requirements between the edge wrapping member 1 and the vehicle body environmental member 3. During the phase change process, only the deformation section 201 undergoes bending deformation, and the setting of the support section 202 plays a role in supporting and fixing the position of the deformation section 201 within the edge wrapping member 1.

[0068] In this embodiment, as Figure 3 、 Figure 4 、 Figure 6 、 Figure 8 shown, the cross-section of the deformation section 201 is an arc bent towards the vehicle body environmental member 3, and the deformation section 201 is preset with a deformation amount bent towards the vehicle body environmental member 3 (i.e., when the shape memory alloy member 2 is in the low-temperature phase shape, the deformation section 201 is closer to the vehicle body environmental member 3). Of course, according to different assembly requirements, the deformation section 201 can also be preset with a deformation amount bent away from the vehicle body environmental member 3 (i.e., when the shape memory alloy member 2 is in the high-temperature phase shape, the deformation section 201 is closer to the vehicle body environmental member 3), and the shape, deformation amount, and deformation direction of the deformation section 201 can be determined according to the theoretical model.

[0069] Furthermore, as Figure 3 、 Figure 4 、 Figure 6 、 Figure 8 shown, the edge wrapping member 1 corresponding to the support section 202 is connected to the window glass 6. Among them, the edge wrapping member 1 corresponding to the support section 202 can be fixedly wrapped around the edge position of the window glass 6, and at least part of the support section 202 is along the edge wrapping member 1 wrapped around the edge position of the window glass 6. Of course, the edge wrapping member 1 corresponding to the support section 202 can also be fixed to the surface of the window glass 6 in other forms, as long as the stable installation requirements of the window edge wrapping structural member are ensured.

[0070] In an alternative embodiment of the present invention, as Figures 3 to 9As shown in the figure, a foaming buffer layer 4 is arranged on the surface of the side of the deformation section 201 facing away from the vehicle body environmental part 3 along the extension direction of the deformation section 201, and there is no adhesive force or only a weak adhesive force between the surface of the side of the deformation section 201 facing the vehicle body environmental part 3 and the internal contact surface A of the edge wrapping part 1 (which can be achieved by arranging an anti-adhesive layer between the deformation section 201 and the internal contact surface of the edge wrapping part 1).

[0071] After the installation is completed, during the process of the shape memory alloy part 2 changing from the high-temperature phase shape to the low-temperature phase shape, the edge wrapping part 1 is adapted to the vehicle body environmental part 3. Even if the shape memory alloy part 2 subsequently returns to the high-temperature phase shape, since there is no adhesive force or only a weak adhesive force between the deformation section 201 and the internal contact surface A of the edge wrapping part 1, the inner surface of the edge wrapping part 1 will not deform following the shape memory alloy part 2, but still remains in an adapted state with the vehicle body environmental part 3; in addition, since the foaming buffer layer 4 is arranged between the surface of the edge wrapping part 1 and the deformation section 201 of the shape memory alloy part 2, and the foaming buffer layer 4 itself has elasticity, during the deformation process of the shape memory alloy part 2 from the high-temperature phase shape to the low-temperature phase shape, the inner surface of the edge wrapping part 1 will deform to adjust the gap between the vehicle body environmental parts 3, and the setting of the foaming buffer layer 4 can reduce the tensile deformation of the outer surface of the edge wrapping part 1 in the direction towards the vehicle body environmental part 3 following the shape memory alloy part 2, thereby helping to reduce the deformation amount of the outer surface of the edge wrapping part 1 and avoiding a large impact on its appearance caused by the deformation of the edge wrapping part 1, and ensuring the beauty of the product.

[0072] Furthermore, the foaming buffer layer 4 can be connected to the surface of the deformation section 201 by, but not limited to, injection molding or bonding. Among them, the foaming buffer layer 4 can be made of, but not limited to, low-density and soft foaming materials.

[0073] In an alternative embodiment of the present invention, as Figure 3 、 Figure 4 、 Figure 6 、 Figure 8 shown, at least one deformation groove 5 is arranged on one side of the edge wrapping part 1 in the same direction as its pre-deformation direction. Among them, the deformation groove 5 can be arranged between the tongue 101 of the edge wrapping part 1 and the deformation section 201, or can be arranged at the middle position of the deformation section 201, or can be arranged at the connection position between the deformation section 201 and the support section 202. The number, specific position and shape of the deformation groove 5 can be set according to the bending shape and bending amplitude of the edge wrapping part 1, as long as it can ensure that the position relationship between the edge wrapping part 1 and the vehicle body environmental part 3 can be satisfied in the vehicle-mounted state, and no limitation is made here.

[0074] In an alternative embodiment of the present invention, as Figure 11 shown, a decorative part 8 is arranged on the surface of the edge wrapping part 1 to achieve the effects of decoration and beauty, and can also play a certain protective role for the edge wrapping part 1.

[0075] Further, the decorative member 8 can be, but is not limited to, a bright strip.

[0076] The characteristics and advantages of the window edge protection structure member of the present invention are as follows:

[0077] A memory alloy member 2 is added to the window edge protection structure member. Through the phase change characteristics of the memory alloy member 2 at different temperatures, the memory alloy member 2 can deform between the high-temperature phase shape and the low-temperature phase shape according to a preset deformation amount, so as to achieve the purpose of adapting the edge wrapping member 1 to the vehicle body environment member 3 in the installed state, thereby shortening the trial-and-error and modification time in the manufacturing process of the edge wrapping member 1, ensuring that the edge wrapping member 1 can meet the adaptation with the vehicle body environment member 3, and improving production efficiency and product quality.

[0078] Embodiment 2

[0079] As Figures 3 to 11 shown, the present invention provides a window, which includes a glass 6 and the above-mentioned window edge wrapping structure member. The window edge wrapping structure member is connected to the edge of the glass 6, and the window edge wrapping structure member is in contact with or has a gap that meets the adaptation requirements with the vehicle body environment member 3 to meet the vehicle installation requirements.

[0080] Further, as Figure 3 、 Figure 4 、 Figure 6 、 Figure 8 、 Figure 10 shown, the glass 6 and the vehicle body environment member 3 are adhesively fixed through an adhesive layer 7. Among them, the adhesive layer 7 can be, but is not limited to, an adhesive layer formed by PU glue.

[0081] Embodiment 3

[0082] As Figure 12 shown, the present invention provides a manufacturing method of a window edge wrapping structure member. The manufacturing method of the window edge wrapping structure member includes the following steps:

[0083] Step S1: Preset the deformation amount of the memory alloy member 2. By presetting the pre-deformation data of the memory alloy member 2, it can be used to form the low-temperature phase shape of the memory alloy member 2;

[0084] Step S2: Before injection molding, heat the memory alloy member 2 to make it in the high-temperature phase shape, so that the memory alloy member 2 deforms to the theoretical shape;

[0085] Step S3: Inject and mold the memory alloy member 2 in the theoretical shape (i.e., in the theoretical position 10) and the edge wrapping member 1 to obtain a window edge wrapping structure member in the theoretical shape;

[0086] Further, in step S3, the memory alloy member 2 in the theoretical shape (i.e., in the theoretical position 10) and the edge wrapping member 1 are placed in a mold and integrally injection molded.

[0087] Step S4: Cool the window edge wrapping structural member until the shape memory alloy member 2 is in the low-temperature phase shape, so that the shape memory alloy member 2 resumes the preset deformation amount, and adjust the shape of the edge wrapping member 1 back to the pre-deformed position 20 through the deformation of the shape memory alloy member 2, thereby obtaining the window edge wrapping structural member in the vehicle-mounted shape.

[0088] In an alternative embodiment of the present invention, before step S1, it is necessary to obtain the theoretical data of the window edge wrapping structural member and develop a mold according to the theoretical data.

[0089] Furthermore, the theoretical data of the window edge wrapping structural member at least includes the theoretical data of the shape memory alloy member 2, the theoretical data of the edge wrapping member 1, and the theoretical data of the glass 6.

[0090] In an alternative embodiment of the present invention, as Figure 13 shown, after step S4, the manufacturing method of the window edge wrapping structural member further includes:

[0091] Step S5: Cooperatively install the window edge wrapping structural member with the vehicle body environment member 3;

[0092] Specifically, place the window edge wrapping structural member into the inspection fixture to detect the assembly effect of the window edge wrapping structural member and the environment member (vehicle body environment member 3).

[0093] Step S6: If the window edge wrapping structural member and the vehicle body environment member 3 reach a matching state, the product is qualified; if the window edge wrapping structural member and the vehicle body environment member 3 do not reach a matching state, only need to re-adjust the deformation amount of the shape memory alloy member 2 and re-form the low-temperature phase shape of the shape memory alloy member 2;

[0094] Step S7: Repeat the operations of step S2 to step S5 until the window edge wrapping structural member and the vehicle body environment member 3 reach a matching state.

[0095] Among them, the matching state in step S6 and step S7 can be set according to the actual vehicle-mounted requirements.

[0096] The characteristics and advantages of the manufacturing method of the window edge wrapping structural member of the present invention are:

[0097] First, in the manufacturing method of the window edge wrapping structural member, by adding a shape memory alloy member 2 in the edge wrapping member 1, and through the phase change characteristics of the shape memory alloy member 2 at different temperatures, the deformation amount of the edge wrapping member 1 can be preset, so as to achieve the purpose of matching the edge wrapping member 1 with the vehicle body environment member 3 in the installation state, thereby shortening the modification time in the manufacturing process of the edge wrapping member 1 and reducing the trial-and-error loss.

[0098] II. Manufacturing method of the window edge wrapping structural member. By adding a shape memory alloy member 2 into the edge wrapping member 1, the deformation amount of the edge wrapping member 1 can be preset according to the phase change characteristics of the shape memory alloy member 2 at different temperatures, thereby reducing the design workload of the pre-deformation of the edge wrapping member 1, improving the production efficiency, and ensuring the product quality.

[0099] III. Manufacturing method of the window edge wrapping structural member. By adding a shape memory alloy member 2 into the edge wrapping member 1, the setting of the reinforcing member in the edge wrapping member 1 can be replaced, and the strength of the edge wrapping member 1 can be improved.
