Abstract
Description
Technical Field
[0001] This application relates to the field of automotive parts technology, specifically to a front hood and vehicle. Background Technology
[0002] The hood, also known as the engine cover or engine cover, is usually located at the opening of the vehicle's engine compartment. It is used to open or close the engine compartment, protecting the engine and other components inside from environmental factors such as rain and dust. It also facilitates the inspection, maintenance, and repair of the engine and other components.
[0003] In related technologies, the front cover is usually made of thin metal sheet, which is prone to deformation during the baking stage of production, resulting in a low yield rate of the front cover. Summary of the Invention
[0004] This invention provides a front hood and vehicle, aiming to solve the problem of low yield rate of front hoods.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0006] In a first aspect, embodiments of this application provide a front cover, which includes a cover plate and a first support member. The cover plate has a mounting surface, and the first support member is disposed on the mounting surface. The coefficient of thermal expansion of the first support member is less than that of the cover plate.
[0007] According to the above technical means, since the coefficient of thermal expansion of the first support is less than that of the cover plate, the thermal deformation of the first support during the baking process will be less than that of the cover plate. The first support set on the cover plate mounting surface can limit the deformation of the cover plate, thereby reducing the overall deformation of the front cover and improving the yield of the front cover.
[0008] In one possible implementation, the material of the first support member includes an aluminum alloy; and / or, the material of the cover plate includes polyphenylene sulfide.
[0009] Based on the aforementioned technical methods, aluminum alloys possess excellent thermal conductivity. Using aluminum alloy to fabricate the first support component allows heat to be quickly and evenly distributed throughout the component during baking, contributing to more uniform thermal stress distribution. This prevents misalignment between the first support component and the cover plate, thereby reducing the overall deformation of the front cover and improving its yield rate. Polyphenylene sulfide (PPS) exhibits good thermal stability and mechanical strength, with excellent resistance to heat deformation. Using PPS to fabricate the cover plate reduces deformation during baking, thus minimizing overall deformation of the front cover and improving its yield rate.
[0010] In one possible implementation, the first support member has a first through hole, the axis of which intersects the mounting surface.
[0011] According to the above-mentioned technical means, setting a first through hole on the first support member can reduce the weight of the first support member and help to make the front cover lighter.
[0012] In one possible implementation, the first support member includes a first frame and a first reinforcing rib. The first frame is disposed on the mounting surface and surrounds the first reinforcing rib. The first reinforcing rib has a first end and a second end facing away from each other, and the first end and the second end are connected to the first frame. The first reinforcing rib and the first frame together form a first through hole.
[0013] According to the above-mentioned technical means, the first reinforcing rib can increase the structural strength of the first support member, which helps to reduce the overall deformation of the front cover during the baking process, thereby improving the yield of the front cover.
[0014] In one possible implementation, the first frame includes a first front frame, a first rear frame, and two first connecting frames. The first front frame is connected to a first end of a first reinforcing rib, and the first rear frame is disposed opposite to the first front frame and connected to a second end of the first reinforcing rib. The first connecting frames are connected to the first front frame and the first rear frame, and the first reinforcing rib is located between the two first connecting frames. The number of first reinforcing ribs is plurality of, with at least two first reinforcing ribs intersecting and connected to each other.
[0015] According to the above-mentioned technical means, the cross-arranged first reinforcing ribs can further increase the structural strength of the first support member, which helps to further reduce the overall deformation of the front cover during the baking process, thereby improving the yield of the front cover.
[0016] In one possible implementation, a limiting groove is provided on the mounting surface, and the first support member is disposed within the limiting groove.
[0017] According to the above-mentioned technical means, during the assembly of the front cover, the limiting groove can guide and position the first support member, which helps to improve the assembly efficiency of the front cover.
[0018] In one possible implementation, the front cover further includes a second support member disposed on the side of the first support member opposite to the cover plate. The first support member has a first front end and a first rear end facing away from each other, and the second support member has a second front end and a second rear end facing away from each other. The second front end is connected to the first front end, and the second rear end is located on the side of the first front end closer to the first rear end, with a gap between the second rear end and the first support member.
[0019] Based on the aforementioned technical means, the second support member, together with the first support member, can provide more reliable support for the cover plate, which helps to further reduce the overall deformation of the front cover during the baking process. Furthermore, in the event of a collision between the front cover and a pedestrian, the gap between the first and second support members can absorb some of the collision energy, thereby reducing the impact injury to the pedestrian.
[0020] In one possible implementation, the first support member has a crumple groove on the side near the mounting surface, and the crumple groove extends through the first support member along the arrangement direction of the first front end and the first rear end.
[0021] According to the aforementioned technical means, when the front cover collides with a pedestrian, the first support member can deform and break along the crumple zone. During this process, on the one hand, the first support member absorbs some of the collision energy as it breaks along the crumple zone, thus reducing the impact injury to the pedestrian. On the other hand, the portion of the first support member near the crumple zone protrudes towards the cover plate, forming a conical structure with the second support member. This allows the cover plate to lift the pedestrian's head, protecting it and reducing impact injury. Therefore, providing a crumple zone on the side of the first support member near the mounting surface improves the pedestrian protection performance of the front cover.
[0022] In one possible implementation, the second support member is provided with a second through hole, the axis of which intersects the mounting surface.
[0023] According to the above-mentioned technical means, setting a second through hole on the second support member can reduce the weight of the second support member and help to make the front cover lighter.
[0024] In one possible implementation, the second support member includes a second frame and a second reinforcing rib. The second frame has a second front end and a second rear end, and the second frame is arranged around the second reinforcing rib. The second reinforcing rib has a third end and a fourth end facing each other, and the third end and the fourth end are connected to the second frame. The second reinforcing rib and the second frame together form a second through hole.
[0025] According to the above-mentioned technical means, the second reinforcing rib can increase the structural strength of the second support member, so that the second support member and the first support member can provide more reliable support for the cover plate, which helps to reduce the overall deformation of the front cover during the baking process, thereby improving the yield of the front cover.
[0026] In one possible implementation, the second frame includes a second front frame, a second rear frame, and two second connecting frames. The second front frame has a second front end and is connected to the third end of the second reinforcing rib. The second rear frame has a second rear end and is disposed opposite to the second front frame, and is connected to the fourth end of the second reinforcing rib. The second connecting frames are connected to the second front frame and the second rear frame, and the second reinforcing rib is located between the two second connecting frames. The number of second reinforcing ribs is multiple, with at least two second reinforcing ribs intersecting and connected to each other.
[0027] According to the above-mentioned technical means, the cross-set second reinforcing ribs can further increase the structural strength of the second support member. In this way, the second support member and the first support member can provide more reliable support for the cover plate, which helps to further reduce the overall deformation of the front cover during the baking process, thereby improving the yield of the front cover.
[0028] In one possible implementation, the front hood further includes a connecting assembly connected to the second support member, and the connecting assembly is used to connect to the vehicle body. The connecting assembly and the second support member are integrally formed.
[0029] According to the above-mentioned technical means, the integral molding of the connecting component and the second support component can reduce the number of parts of the front cover and shorten the manufacturing process, while also avoiding the risk of front cover deformation due to fluctuations in the dimensional accuracy of the connecting component.
[0030] In one possible implementation, the connecting assembly includes at least one of a locking hook, a connector, and a mounting member. The locking hook is located at the second front end of the second support member and is used to lock or unlock with a lock body on the vehicle body; the connector is located at the second rear end of the second support member and is used to connect with the vehicle body; the mounting member is used to connect with a support rod on the vehicle body.
[0031] By integrating the locking hook, connector, and mounting component onto the second support component using the aforementioned technical means, the number of parts in the front cover can be reduced, thereby simplifying the assembly process of the front cover and improving the assembly efficiency of the front cover.
[0032] In one possible implementation, the second support member and the first support member are integrally formed.
[0033] Based on the above-mentioned technical means, not only can the connection strength of the first support and the second support be improved, thereby providing more reliable support for the cover plate and reducing the risk of deformation of the front cover; it can also simplify the assembly process of the front cover, thereby improving the assembly efficiency of the front cover.
[0034] In one possible implementation, the density of the cover plate is less than the density of the first support member; and / or, the density of the cover plate is less than the density of the second support member.
[0035] According to the above-mentioned technical means, compared with the first support and the second support, the cover plate uses a material with a lower density, which can reduce the weight of the front cover and help to make the front cover lightweight.
[0036] Secondly, embodiments of this application also provide a vehicle, which includes a body and a front hood in the first aspect and any possible implementation thereof, the body having an engine compartment with an opening, the front hood being connected to the body and covering the opening of the engine compartment.
[0037] It should be noted that the technical effects brought about by the implementation method in the second aspect can be referred to the technical effects brought about by the corresponding implementation method in the first aspect, and will not be repeated here.

Detailed Implementation
[0046] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0047] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0048] See Figure 1 This application provides a vehicle 1000, which can be a passenger car such as a sedan, a sport utility vehicle (SUV), or a multi-purpose vehicle (MPV). This application does not specifically limit the vehicle to such a vehicle.
[0049] The vehicle 1000 includes a body 100, which has an engine compartment with an opening for mounting components such as the engine of the vehicle 1000. For example, the engine compartment is located at the front of the vehicle 1000, and the opening is located on the upper side of the vehicle 1000.
[0050] Additionally, the vehicle 1000 may also include a front cover 200, which is connected to the body 100 and covers the opening of the engine compartment. In this way, the front cover 200 can protect the engine and other components in the engine compartment from environmental factors such as rain and dust, thereby reducing the risk of engine and other component failure.
[0051] Understandably, the front cover 200 can be configured to rotate relative to the body 100, allowing the front cover 200 to rotate relative to the body 100 to open or close the engine compartment. This configuration facilitates the inspection, maintenance, and repair of components such as the engine.
[0052] In some embodiments, see Figure 1 and Figure 2 The front cover 200 includes a connecting component 1 for connecting the body 100.
[0053] For example, such as Figure 3 As shown, the connecting assembly 1 includes at least one of a locking hook 11, a connector 12, and a mounting member 13.
[0054] When the connecting assembly 1 includes a connector 12, the connector 12 can be rotatably connected to the vehicle body 100 to realize the rotatable connection between the front cover 200 and the vehicle body 100, thereby enabling the front cover 200 to rotate relative to the vehicle body 100 to open or close the engine compartment.
[0055] It should be noted that the number of connectors 12 can be one or more, and the specific number can be selected according to the actual situation. This application does not limit this. When there are multiple connectors 12, the multiple connectors 12 can be arranged at intervals along the width direction of the vehicle 1000. Multiple connectors 12 can improve the reliability of the connection between the front cover 200 and the body 100.
[0056] When the connecting assembly 1 includes a locking hook 11, the vehicle 1000 may also include a lock body disposed on the vehicle body 100, and the locking hook 11 is used to lock or unlock with the lock body on the vehicle body 100. In the locked state, the locking hook 11 is connected to the lock body to restrict the movement of the front cover 200 relative to the vehicle body 100, so that the front cover 200 is held in a position with the engine compartment closed; in the unlocked state, the locking hook 11 is separated from the lock body, and the front cover 200 can move relative to the vehicle body 100 to open or close the engine compartment.
[0057] When the connecting assembly 1 includes the mounting member 13, the vehicle 1000 may also include a support rod, one end of which is connected to the mounting member 13 and the other end of which is connected to the vehicle body 100. When the front hood 200 is in the open engine compartment position, the support rod can support the front hood 200 to keep the front hood 200 in the open engine compartment position, which facilitates the inspection, maintenance and repair of components such as the engine.
[0058] The number of mounting components 13 can be one or more, depending on the actual situation, and this application does not limit this. When there are multiple mounting components 13, the multiple mounting components 13 can be arranged at intervals along the width direction of the vehicle 1000, and each mounting component 13 can be connected to a corresponding support rod, so that multiple support rods can provide more reliable support for the front cover 200.
[0059] In some embodiments, see Figure 4 and Figure 5 The front cover 200 includes a cover plate 2 and a first support member 3. The cover plate 2 has a mounting surface 21, and the first support member 3 is disposed on the mounting surface 21. It is understood that the mounting surface 21 can be a surface of the cover plate 2 in its thickness direction; the first support member 3 can provide support for the cover plate 2 to reduce the risk of deformation of the cover plate 2.
[0060] The coefficient of thermal expansion of the first support member 3 is less than that of the cover plate 2. With this configuration, the thermal deformation of the first support member 3 during baking is less than that of the cover plate 2. The first support member 3, which is located on the mounting surface 21 of the cover plate 2, can limit the deformation of the cover plate 2, thereby reducing the overall deformation of the front cover 200 and improving the yield of the front cover 200.
[0061] It should be noted that the first support member 3 can be connected to the cover plate 2 by one or more combinations of welding, riveting, or bonding. The specific method can be selected according to the actual situation, and this application does not limit it. For example, the first support member 3 can be bonded to the cover plate 2 with adhesive. This method can simplify the operation process, help improve production efficiency, and ensure the consistency of quality.
[0062] In some embodiments, the material of the first support member 3 includes aluminum alloy, for example, the first support member 3 is made of aluminum alloy.
[0063] Understandably, aluminum alloy has excellent thermal conductivity. Using aluminum alloy to make the first support member 3 allows heat to be quickly and evenly distributed throughout the first support member 3 during baking, helping to make the thermal stress distribution of the first support member 3 more uniform. This prevents misalignment between the first support member 3 and the cover plate 2, thereby reducing the overall deformation of the front cover 200 and improving the yield rate of the front cover 200.
[0064] In some embodiments, the material of the cover plate 2 includes polyphenylene sulfide, for example, the cover plate 2 is made of polyphenylene sulfide.
[0065] It is understandable that polyphenylene sulfide has good thermal stability and mechanical strength, and excellent resistance to heat deformation. Using polyphenylene sulfide to make the cover plate 2 can reduce the amount of deformation generated by the cover plate 2 during the baking process, thereby reducing the overall deformation of the front cover 200 and improving the yield of the front cover 200.
[0066] In some embodiments, see Figure 4 The first support member 3 is provided with a first through hole 31, and the axis of the first through hole 31 is perpendicular to the mounting surface 21 (e.g., Figure 5 (As shown) intersects, for example, the axis of the first through hole 31 is perpendicular to the mounting surface 21. Perpendicularity can include absolute perpendicularity and approximately perpendicularity, with an acceptable deviation of approximately perpendicularity within 5°.
[0067] It is understandable that providing a first through hole 31 on the first support member 3 can reduce the weight of the first support member 3 and help to make the front cover 200 lighter.
[0068] It should be noted that one or more first through holes 31 may be provided on the first support member 3, and the specific selection can be made according to the actual situation. This application does not limit this.
[0069] Furthermore, this application does not specifically limit the shape of the first through hole 31. For example, the shape of the first through hole 31 can be circular, elliptical, polygonal, etc. The shape of the first through hole 31 can refer to the shape of the orthographic projection of the first through hole 31 on the mounting surface 21 of the cover plate 2, or the shape of the first through hole 31 can refer to the shape of the cross-section of the first through hole 31 perpendicular to its axis.
[0070] For example, such as Figure 4 As shown, the first through hole 31 is polygonal in shape, for example, the first through hole 31 is triangular, wherein the triangle may have rounded corners. It is understood that, compared to setting the first through hole 31 as a circle or ellipse, setting the first through hole 31 as a polygon helps to increase the structural strength of the first support member 3 and can reduce the risk of deformation of the front cover 200.
[0071] In some embodiments, see Figure 4 The first support member 3 includes a first frame 32 and a first reinforcing rib 33. The first frame 32 is disposed on the mounting surface 21 and surrounds the first reinforcing rib 33. The first reinforcing rib 33 has a first end and a second end facing away from each other, and the first end and the second end are connected to the first frame 32. That is, the first reinforcing rib 33 is disposed on the inner side of the first frame 32, and the two opposite ends of the first reinforcing rib 33 are connected to the first frame 32.
[0072] In this configuration, the first reinforcing rib 33 and the first frame 32 form the first through hole 31. It is understood that the first reinforcing rib 33 increases the structural strength of the first support member 3, which helps to reduce the overall deformation of the front cover 200 during baking, thereby improving the yield rate of the front cover 200.
[0073] The first reinforcing rib 33 can also be set on the mounting surface 21 (e.g.) Figure 5 As shown in the figure, the first reinforcing rib 33 and the first frame 32 can simultaneously provide support for the cover plate 2, which helps to reduce the risk of deformation of the cover plate 2.
[0074] It should be noted that the first support member 3 may include one or more first reinforcing ribs 33, which can be selected according to the actual situation, and this application does not limit this. Where the first support member 3 includes multiple first reinforcing ribs 33, the multiple first reinforcing ribs 33 may be arranged at intervals, or at least some of the first reinforcing ribs 33 may be arranged intersecting each other.
[0075] The following describes some embodiments of this application by taking the first support member 3 as an example, which includes a plurality of first reinforcing ribs 33 (i.e., the number of first reinforcing ribs 33 is plurality).
[0076] In some embodiments, see Figure 4 The first frame 32 includes a first front frame 321, a first rear frame 322 and two first connecting frames 323. The first rear frame 322 is disposed opposite to the first front frame 321, and the first connecting frames 323 are connected to the first front frame 321 and the first rear frame 322.
[0077] For example, the two ends of the first connecting frame 323 are connected to the first front frame 321 and the first rear frame 322, respectively. The two ends of the first front frame 321 are connected to the two first connecting frames 323, respectively. The two ends of the first rear frame 322 are connected to the two first connecting frames 323, respectively. That is, the first front frame 321, the first rear frame 322 and the two first connecting frames 323 are all interconnected through their ends.
[0078] In addition, the first reinforcing rib 33 is located between the two first connecting frames 323, and the first front frame 321 is connected to the first end of the first reinforcing rib 33, and the first rear frame 322 is connected to the second end of the first reinforcing rib 33.
[0079] Based on this, such as Figure 4 As shown, at least two first reinforcing ribs 33 are arranged in a cross configuration, and the two cross-arranged first reinforcing ribs 33 are connected to each other. For example, the first support member 3 includes five first reinforcing ribs 33, wherein one first reinforcing rib 33 extends along the arrangement direction of the first front end 34 and the first rear end 35, and two cross-arranged first reinforcing ribs 33 are provided on each of the opposite sides of the first reinforcing rib 33.
[0080] Understandably, the cross-set first reinforcing ribs 33 can further increase the structural strength of the first support member 3, which helps to further reduce the overall deformation of the front cover 200 during the baking process, thereby improving the yield of the front cover 200.
[0081] In some embodiments, see Figure 5 The mounting surface 21 is provided with a limiting groove 211, and the first support member 3 (such as...) Figure 4 (As shown) is set in the limiting groove 211. In this way, during the assembly of the front cover 200, the limiting groove 211 can guide and position the first support member 3, which helps to improve the assembly efficiency of the front cover 200.
[0082] The shape of the limiting groove 211 can be adapted to the shape of the first support member 3, so that the limiting groove 211 can better guide and position the first support member 3 during the assembly of the front cover 200. In addition, when the first support member 3 is bonded to the cover plate 2 with adhesive, before the adhesive cures, the limiting groove 211 can also cooperate with the first support member 3 to limit the first support member 3 from moving relative to the cover plate 2.
[0083] In some embodiments, see Figure 3 The front cover 200 also includes a second support member 4, which is disposed on the first support member 3 away from the cover plate 2 (e.g., Figure 2 (as shown) one side.
[0084] Among them, such as Figure 4 As shown, the first support member 3 has a first front end 34 and a first rear end 35 facing away from each other. For example, the first front end 34 is the end of the first front frame 321 that is away from the first rear frame 322, and the first rear end 35 is the end of the first rear frame 322 that is away from the first front frame 321.
[0085] In addition, such as Figure 3 and Figure 4 As shown, the second support member 4 has a second front end 41 and a second rear end 42 facing away from each other. The second front end 41 is connected to the first front end 34, and the second rear end 42 is located on the side of the first front end 34 near the first rear end 35, with a gap 5 between the second rear end 42 and the first support member 3. In this case, the connection between the first support member 3 and the second support member 4 forms a V-shaped structure.
[0086] Understandably, the second support member 4, together with the first support member 3, can provide more reliable support for the cover plate 2, which helps to further reduce the overall deformation of the front cover 200 during the baking process. In addition, when the front cover 200 collides with a pedestrian, the gap 5 between the first support member 3 and the second support member 4 can absorb some of the collision energy, helping to reduce the collision injury suffered by the pedestrian.
[0087] In some embodiments, such as Figure 3 As shown, the second support member 4 is provided with a second through hole 43, the axis of which intersects the mounting surface 21. For example, the axis of the second through hole 43 is perpendicular to the surface of the second support member 4 near the first support member 3. Perpendicularity can include absolute perpendicularity and approximate perpendicularity, and the acceptable deviation range for approximate perpendicularity can be within 5°.
[0088] Understandably, providing a second through hole 43 on the second support member 4 can reduce the weight of the second support member 4 and help to make the front cover 200 lighter.
[0089] It should be noted that one or more second through holes 43 may be provided on the second support member 4, and the specific selection can be made according to the actual situation. This application does not limit this.
[0090] Furthermore, this application does not specifically limit the shape of the second through hole 43. For example, the shape of the second through hole 43 can be circular, elliptical, polygonal, etc. The shape of the second through hole 43 can refer to the shape of the orthographic projection of the second through hole 43 on the mounting surface 21 of the cover plate 2, or the shape of the second through hole 43 can refer to the shape of the cross-section of the second through hole 43 perpendicular to its axis.
[0091] For example, the second through hole 43 is polygonal in shape, such as a triangle, where the triangle may have rounded corners. It is understood that making the second through hole 43 polygonal, compared to options that make it circular or elliptical, helps to increase the structural strength of the second support member 4 and can reduce the risk of deformation of the front cover 200.
[0092] In some embodiments, see Figure 3 The second support member 4 includes a second frame 44 and a second reinforcing rib 45. The second frame 44 is arranged around the second reinforcing rib 45. The second reinforcing rib 45 has a third end and a fourth end facing away from each other, and the third end and the fourth end are connected to the second frame 44. That is, the second reinforcing rib 45 is arranged inside the second frame 44, and the two ends of the second reinforcing rib 45 facing away from each other are connected to the second frame 44.
[0093] It should be noted that the second frame 44 has a second front end 41 and a second rear end 42, that is, the second front end 41 and the second rear end 42 of the second support member 4 are the same as the second front end 41 and the second rear end 42 of the second frame 44. At this time, the first front end 34 of the first support member 3 (such as...) Figure 4 (As shown) is connected to the second border 44.
[0094] In this configuration, the second reinforcing rib 45 and the second frame 44 form the second through hole 43. It is understood that the second reinforcing rib 45 increases the structural strength of the second support member 4, allowing the second support member 4 and the first support member 3 to provide more reliable support for the cover plate 2. This helps reduce the overall deformation of the front cover 200 during baking, thereby improving the yield rate of the front cover 200.
[0095] It should be noted that the second support member 4 may include one or more second reinforcing ribs 45, which can be selected according to the actual situation, and this application does not limit this. Where the second support member 4 includes multiple second reinforcing ribs 45, the multiple second reinforcing ribs 45 may be arranged at intervals, or at least some of the second reinforcing ribs 45 may be arranged to cross each other.
[0096] The following describes some embodiments of this application by taking the second support member 4 as an example, which includes a plurality of second reinforcing ribs 45 (i.e., the number of second reinforcing ribs 45 is plurality).
[0097] In some embodiments, such as Figure 3 As shown, the second frame 44 includes a second front frame 441, a second rear frame 442 and two second connecting frames 443. The second rear frame 442 is disposed opposite to the second front frame 441, and the second connecting frames 443 are connected to the second front frame 441 and the second rear frame 442.
[0098] For example, the two ends of the second connecting frame 443 are connected to the second front frame 441 and the second rear frame 442 respectively. The two ends of the second front frame 441 are connected to the two second connecting frames 443 respectively, and the two ends of the second rear frame 442 are connected to the two second connecting frames 443 respectively. That is to say, the second front frame 441, the second rear frame 442 and the two second connecting frames 443 are all interconnected through their ends.
[0099] It should be noted that the second front frame 441 has a second front end 41, that is, the end of the second front frame 441 that is away from the second rear frame 442 is the second front end 41; the second rear frame 442 has a second rear end 42, that is, the end of the second rear frame 442 that is away from the second front frame 441 is the second rear end 42.
[0100] In addition, the second reinforcing rib 45 is located between the two second connecting frames 443, and the second front frame 441 is connected to the third end of the second reinforcing rib 45, and the second rear frame 442 is connected to the fourth end of the second reinforcing rib 45.
[0101] Based on this, such as Figure 3 As shown, at least two second reinforcing ribs 45 are arranged intersectingly, and the two intersecting second reinforcing ribs 45 are connected to each other. For example, the second support member 4 includes five second reinforcing ribs 45, wherein one second reinforcing rib 45 extends along the arrangement direction of the second front end 41 and the second rear end 42, and two intersecting second reinforcing ribs 45 are provided on each of the opposite sides of the second reinforcing rib 45.
[0102] Understandably, the cross-set second reinforcing ribs 45 can further increase the structural strength of the second support member 4, so that the second support member 4 and the first support member 3 can provide more reliable support for the cover plate 2, which helps to further reduce the overall deformation of the front cover 200 during the baking process, thereby improving the yield of the front cover 200.
[0103] In some embodiments, see Figure 4 and Figure 5The first support member 3 has a contraction groove 36 on the side near the mounting surface 21. The contraction groove 36 penetrates the first support member 3 along the arrangement direction of the first front end 34 and the first rear end 35. For example, the contraction groove 36 is located in the middle of the first support member 3, or the first support member 3 is symmetrically arranged with respect to the contraction groove 36.
[0104] Understandably, when the front cover 200 collides with a pedestrian, the first support member 3 can deform along the crumple zone 36. During this process, on the one hand, the first support member 3 absorbs some of the collision energy as it deforms along the crumple zone 36, thus reducing the impact injury to the pedestrian. On the other hand, the portion of the first support member 3 near the crumple zone 36 protrudes towards the cover plate 2, forming a conical structure with the second support member 4. This allows the cover plate 2 to lift the pedestrian's head, protecting it and reducing impact injury. Therefore, providing the crumple zone 36 on the side of the first support member 3 near the mounting surface 21 improves the pedestrian protection performance of the front cover 200.
[0105] In some embodiments, such as Figure 3 As shown, the connecting component 1 is connected to the second support member 4. For example, the connecting component 1 and the second support member 4 are integrally formed. This arrangement reduces the number of parts in the front cover 200 and shortens the manufacturing process, while also avoiding the risk of deformation of the front cover 200 due to fluctuations in the dimensional accuracy of the connecting component 1.
[0106] For example, such as Figure 3 As shown, the connecting assembly 1 includes a locking hook 11, a connector 12, and a mounting member 13. The locking hook 11 is disposed at the second front end 41 of the second support member 4, the connector 12 is disposed at the second rear end 42 of the second support member 4, and the mounting member 13 is disposed between the locking hook 11 and the connector 12. The locking hook 11 and the mounting member 13 can be disposed on the second support member 4 away from the cover plate 2 (e.g., Figure 2 On one side (as shown), the connector 12 can be disposed on the side of the first support 3 away from the cover plate 2.
[0107] It is understandable that integrating the locking hook 11, the connector 12 and the mounting part 13 onto the second support member 4 can reduce the number of parts in the front cover 200, thereby simplifying the assembly process of the front cover 200 and improving the assembly efficiency of the front cover 200.
[0108] In some embodiments, see Figure 3The second support member 4 and the first support member 3 are integrally formed. For example, the first support member 3 and the second support member 4 are integrally cast by a casting process. This not only improves the connection strength between the first support member 3 and the second support member 4, thereby providing more reliable support for the cover plate 2 and reducing the risk of deformation of the front cover 200, but also simplifies the assembly process of the front cover 200, thereby improving the assembly efficiency of the front cover 200.
[0109] It should be noted that the connecting component 1 can also be integrally formed with the second support member 4 and the first support member 3. For example, the connecting component 1, the first support member 3, and the second support member 4 can be integrally cast using a casting process. This can further simplify the assembly process of the front cover 200, thereby improving the assembly efficiency of the front cover 200.
[0110] In some embodiments, see Figure 2 and Figure 3 The density of cover plate 2 is less than the density of at least one of the first support member 3 and the second support member 4.
[0111] For example, the density of cover plate 2 is less than that of the first support member 3, and the density of cover plate 2 is less than that of the second support member 4. That is, compared with the first support member 3 and the second support member 4, cover plate 2 uses a material with a lower density, which can reduce the weight of the front cover 200 and help to make the front cover 200 lightweight. For example, the first support member 3 and the second support member 4 are made of aluminum alloy, and cover plate 2 is made of polyphenylene sulfide.
[0112] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
