Description

Technical Field

[0001] The present invention relates to the technical field of vehicle accessories, and particularly relates to a sunroof spoiler device, a sunroof assembly, and a vehicle. Background Art

[0002] With the gradual increase in users' requirements for vehicle functions, panoramic sunroofs have gradually become an indispensable element in vehicle configurations. As a key part of the panoramic sunroof assembly, the panoramic sunroof spoiler device plays a crucial role in regulating the airflow when the sunroof is open, and can effectively reduce or avoid the noise and wind vibration problems generated when the vehicle is driving with the sunroof open.

[0003] However, the spoiler net of the panoramic sunroof is connected to the sunroof frame, and it is also prone to oscillating motion under the influence of airflow when it is in the open state. As a result, problems such as increased noise and vibration occur when the vehicle is driving at high speed. Summary of the Invention

[0004] One of the purposes of the present invention is to provide a sunroof spoiler device to solve the problem that the spoiler net in the prior art is prone to oscillating under the influence of airflow, resulting in increased noise and vibration of the vehicle; the second purpose is to provide a sunroof assembly; the third purpose is to provide a vehicle.

[0005] To achieve the above purposes, the technical solutions adopted by the present invention are as follows:

[0006] A sunroof spoiler device, the sunroof spoiler device includes a spoiler net assembly, at least two spring connection structures, and at least two support springs. The spoiler net assembly is rotatably connected to the sunroof frame device of the sunroof assembly, and at least two of the spring connection structures are distributed at both ends of the spoiler net assembly. One end of each support spring is connected to the corresponding spring connection structure, and the other end of the support spring is slidably connected to the sunroof frame device. The support spring includes a spring long arm, and when the spring long arm is in a deformed state, it retracts the spoiler net assembly. When the spoiler net assembly is unfolded, the spring long arm returns from the deformed state to the initial state, and the support spring in the initial state forms a limit for the spoiler net assembly.

[0007] According to the above technical means, when the sunroof glass is opened, the spoiler net assembly can be driven to unfold through the deformation recovery ability of the spring long arm of the support spring, and the pressure received by the spoiler net assembly during high-speed driving can be buffered through the deformation of the support spring, so that while ensuring the structural stability of the spoiler net assembly, the situation that the spoiler net assembly is affected by airflow and generates oscillating motion, resulting in increased wind noise in the vehicle or aggravated vibration phenomenon, can be alleviated.

[0008] Furthermore, the support spring further includes a slider, a spring helical section, and a spring short arm. The slider is fixedly connected to one end of the spring long arm and forms a sliding connection with the skylight frame device. The spring helical section is located at the end of the spring long arm away from the slider and abuts against the spring connection structure to limit the spring helical section through the spring connection structure. The spring short arm is located at the end of the spring helical section away from the spring long arm and is embedded in the spring connection structure.

[0009] According to the above technical means, different parts of the support spring can be respectively connected to the spoiler net assembly and the skylight frame device, which can improve the disassembly and assembly convenience of the support spring while ensuring the structural strength of the support spring itself.

[0010] Furthermore, the spring connection structure includes a short arm limiting portion and a helical limiting portion. A short arm limiting channel is formed on the short arm limiting portion, and the spring short arm is embedded in the short arm limiting channel. A helical limiting channel is provided on the helical limiting portion, and the helical limiting channel communicates with the short arm limiting channel. Among them, the spring helical section is adapted to the shape of the helical limiting channel to form the limit of the spring helical section.

[0011] According to the above technical means, the spring short arm is limited by the short arm limiting portion, and the spring helical section is limited by the thread limiting portion, which can improve the connection firmness between the support spring and the spoiler net. And it can improve the disassembly and assembly convenience of the support spring.

[0012] Furthermore, the helical limiting portion includes a limiting body, a plurality of body support members, and a plurality of first support ribs. The plurality of body support members are distributed on the four sides of the end face of the limiting body facing the spring helical section to cooperate with the limiting body to form a limiting space for defining the position of the spring helical section. The plurality of first support ribs are spaced apart along the axial direction of the spring helical section, and two adjacent first support ribs form a helical space that is in clearance fit with the spring coils in the spring helical section. The limiting space and the helical space cooperate to form the helical limiting channel, wherein the first support ribs are connected to the body support members.

[0013] According to the above technical means, axial and radial limits can be formed on the spring helical section through the spiral limit channel. Moreover, when the support spring is deformed under force, the deformation force can be transmitted and dispersed from the spring helical section to the spring long arm, the first support rib, and the limit body, and the force transmitted to the first support rib can be further transmitted to the body support member. Thus, the force received by the support spring can be dispersed through the spiral limit, the service life of the support spring can be prolonged, and the support stability of the support spring for the spoiler net assembly can be improved when the vehicle is traveling at high speed.

[0014] Furthermore, the end face of the limit body facing the spring helical section is distributed in an uneven shape.

[0015] According to the above technical means, the structural strength of the limit body can be improved, and the injection molding of the limit body can be facilitated.

[0016] Furthermore, clamping joints are respectively arranged on both sides of the spoiler net assembly, and the clamping joints are matched with the clamping holes opened on the sunroof frame device to form a rotational connection between the spoiler net assembly and the sunroof frame device.

[0017] According to the above technical means, through the clamping fit between the clamping joints and the clamping holes, the disassembly and assembly convenience of the sunroof spoiler device can be further improved. And it is beneficial to reduce the production cost of the sunroof spoiler device.

[0018] Furthermore, the spoiler net assembly includes a spoiler net body, a first side strip, a mesh, and a second side strip. The first side strip is fixedly connected to the spoiler net body. The mesh is fixedly connected to the first side strip, and the second side strip is fixedly connected to the side of the mesh away from the first side strip. Among them, the second side strip is fixedly connected to the sunroof frame device. When the spring long arm returns from the deformed state to the initial state, the spoiler net body drives the first side strip to move away from the sunroof frame device, so that the mesh is unfolded.

[0019] According to the above technical means, the structure of the spoiler net assembly can be simplified, and the production cost of the sunroof spoiler device can be reduced.

[0020] Furthermore, the first side strip is clamped with the spoiler net body; and / or the second side strip is clamped with the sunroof frame device.

[0021] According to the above technical means, the disassembly and assembly convenience of the spoiler net assembly can be improved, and the structure of the sunroof spoiler device can be simplified, which is beneficial to reducing the production cost of the sunroof spoiler device.

[0022] A sunroof assembly includes a sunroof spoiler device and a sunroof frame device as described in any one of the above invention contents. The sunroof frame device is slidably connected to the support spring, and the spoiler net assembly is rotatably connected to the sunroof frame device of the sunroof assembly.

[0023] According to the above technical means, when the sunroof glass is opened, the deformation recovery ability of the long arm of the support spring can be used to drive the spoiler net assembly to deploy, and the deformation of the support spring can be used to buffer the pressure received by the spoiler net assembly during high-speed driving. Thus, while ensuring the structural stability of the spoiler net assembly, the situation where the spoiler net assembly is affected by air flow to generate oscillating motion, resulting in an increase in in-vehicle wind noise or an aggravation of vibration phenomena, etc., can be alleviated, optimizing the product performance of the sunroof assembly.

[0037] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.

[0038] It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. Therefore, only the components related to the present invention are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0039] As the user's demand for vehicle functions gradually increases, panoramic sunroofs have gradually become an indispensable element in vehicle configurations. As a key part of the panoramic sunroof assembly, the panoramic sunroof spoiler device plays a crucial role in regulating the airflow when the sunroof is open, and can effectively reduce or avoid the noise and wind vibration problems generated by the opening of the sunroof during vehicle driving.

[0040] However, the spoiler net of the panoramic sunroof is connected to the sunroof frame, and it is also prone to oscillating motion under the influence of airflow when it is in the open state. As a result, problems such as increased noise and vibration phenomena occur when the vehicle is driving at high speed.

[0041] Based on the above technical problems, the embodiments of the present invention are proposed. The embodiments of the present invention may include a spoiler net assembly 1, at least two spring connection structures 2, and at least two support springs 3. The spoiler net assembly 1 is rotatably connected to the sunroof frame device 5 of the sunroof assembly. At least two of the spring connection structures 2 are distributed at both ends of the spoiler net assembly 1. One end of each support spring 3 is connected to the corresponding spring connection structure 2, and the other end of the support spring 3 is slidably connected to the sunroof frame device 5. The support spring 3 includes a spring long arm 31. When the spring long arm 31 is in a deformed state, it retracts the spoiler net assembly 1. When the spoiler net assembly 1 is unfolded, the spring long arm 31 returns from the deformed state to the initial state, and the support spring 3 in the initial state forms a limit for the spoiler net assembly 1. Thus, when the sunroof glass is opened, the spoiler net assembly 1 can be driven to unfold by the deformation recovery ability of the spring long arm 31 of the support spring 3, and the pressure received by the spoiler net assembly 1 during high-speed driving can be buffered by the deformation of the support spring 3. Therefore, while ensuring the structural stability of the spoiler net assembly 1, the situation that the spoiler net assembly 1 is affected by airflow and generates oscillating motion, resulting in increased wind noise in the vehicle or aggravated vibration phenomena, can be alleviated.

[0042] Refer to Figure 1-7 As shown in [figure reference], the embodiments of the present invention provide a sunroof spoiler device, which may include a spoiler net assembly 1, at least two spring connection structures 2, and at least two support springs 3. The spoiler net assembly 1 is rotatably connected to the sunroof frame device 5 of the sunroof assembly. At least two of the spring connection structures 2 are distributed at both ends of the spoiler net assembly 1. One end of each support spring 3 is connected to the corresponding spring connection structure 2, and the other end of the support spring 3 is slidably connected to the sunroof frame device 5. The support spring 3 includes a spring long arm 31. When the spring long arm 31 is in a deformed state, it retracts the spoiler net assembly 1. When the spoiler net assembly 1 is unfolded, the spring long arm 31 returns from the deformed state to the initial state, and the support spring 3 in the initial state forms a limit for the spoiler net assembly 1.

[0043] In an embodiment of the present invention, the skylight spoiler device may include a spoiler net assembly 1, a spring connection structure 2, and a support spring 3. Among them, the spring connection structure 2 is arranged on the spoiler net assembly 1 for fixing the support spring 3. The spoiler net assembly 1 has the following two states: a retracted state and an unfolded state. When the spoiler net assembly 1 is in the unfolded state, when the air flow passes through the skylight assembly, the air flow can flow through the spoiler net assembly 1 more evenly and dispersedly, thereby reducing the generation of turbulence and noise in the skylight assembly and improving the quiet comfort inside the vehicle body. Among them, by opening and closing the skylight glass of the skylight assembly, the spoiler net assembly 1 is pressed and released to realize the state conversion of the spoiler net assembly 1.

[0044] The skylight frame device 5 can provide support for other components of the skylight assembly. For example, it can limit the skylight glass to prevent the skylight glass from shaking or deforming. In some embodiments, referring to Figure 1 As shown, the skylight frame device 5 may include a skylight front cross beam 51, a skylight first guide rail 52, a skylight second guide rail 53, and a skylight rear cross beam 54. Among them, the skylight front cross beam 51 is arranged close to the front of the vehicle, and the skylight rear cross beam 54 is arranged close to the rear of the vehicle and is opposite to the skylight front cross beam 51. The skylight first guide rail 52 and the skylight second guide rail 53 are distributed at both ends of the skylight rear cross beam 54. Among them, the skylight front cross beam 51, the skylight first guide rail 52, the skylight second guide rail 53, and the skylight rear cross beam 54 enclose a skylight space for installing the skylight glass. The length direction of the spoiler net assembly 1 may be arranged parallel to the length direction of the skylight front cross beam 51. And one end of the spoiler net assembly 1 is rotatably connected to the skylight first guide rail 52, and the other end of the spoiler net assembly 1 is rotatably connected to the skylight second guide rail 53, so as to realize the rotational connection between the spoiler net assembly 1 and the skylight frame device 5, and the spoiler net assembly 1 can rotate freely under the drive of an external force.

[0045] The support spring 3 includes a spring long arm 31, and the spring long arm 31 has a certain structural stiffness. One end of the support spring 3 away from the spring long arm 31 is fixed to the spring connection structure 2, thereby forming a structural support for the spoiler net assembly 1. The spring long arm 31 is slidably connected to the skylight frame device 5. For example, the spring long arm 31 of the support spring 3 close to the skylight first guide rail 52 is slidably connected to the skylight first guide rail 52. The spring long arm 31 of the support spring 3 close to the skylight second guide rail 53 is slidably connected to the skylight second guide rail 53. Thus, the rotation angle of the spoiler net assembly 1 (which can also be called the position of the spoiler net assembly 1 when it is in the unfolded state) can be limited by the angle at the connection between the spring long arm 31 and the guide rail.

[0046] When the long arm 31 of the spring is not deformed (which can also be called the initial state), the long arm 31 of the spring can structurally support the spoiler net assembly 1, can limit the spoiler net assembly 1 in the deployed state, and can, during the high-speed driving of the vehicle, disperse the pressure received at the connection between the spoiler net assembly 1 and the sunroof frame device 5 through the deformation of the support spring 3. Thus, while ensuring the structural stability of the spoiler net assembly 1, it can reduce the phenomena such as increased interior wind noise, abnormal noise, whistling, or wind vibration caused by the oscillating movement of the spoiler net assembly 1 affected by the airflow. Thereby, the riding experience of the passengers (drivers and passengers) can be improved.

[0047] When the sunroof glass presses the spoiler net assembly 1 downward, the spoiler net assembly 1 moves downward close to the sunroof frame device 5. At this time, the long arm 31 of the spring deforms (for example, the long arm 31 of the spring changes from a straight line to a curve). At this time, the long arm 31 of the spring is in a deformed state, and the spoiler net assembly 1 is converted from the deployed state to the retracted state. When the sunroof glass is opened next time, the long arm 31 of the spring deforms and recovers, changing from the deformed state to the initial state. During this process, the support spring 3 drives the spoiler net assembly 1 to deploy.

[0048] In summary, when the sunroof glass is opened, the spoiler net assembly 1 can be driven to deploy through the deformation recovery ability of the long arm 31 of the support spring 3, and the pressure received by the spoiler net assembly 1 during high-speed driving can be buffered through the deformation of the support spring 3. Thus, while ensuring the structural stability of the spoiler net assembly 1, it can reduce the situations such as increased interior wind noise or aggravated vibration phenomena caused by the oscillating movement of the spoiler net assembly 1 affected by the airflow.

[0049] In an optional embodiment of the invention, referring to Figure 2 、 Figure 3 and Figure 4 as shown, the support spring 3 further includes a slider 32, a spring helical section 33, and a spring short arm 34. The slider 32 is fixedly connected to one end of the long arm 31 of the spring and forms a sliding connection with the sunroof frame device 5. The spring helical section 33 is located at the end of the long arm 31 of the spring away from the slider 32 and abuts against the spring connection structure 2 to limit the spring helical section 33 through the spring connection structure 2. The spring short arm 34 is located at the end of the spring helical section 33 away from the long arm 31 of the spring and is embedded in the spring connection structure 2.

[0050] In the embodiments of the present invention, the support spring 3 may further include a slider 32, a spring helical section 33, and a spring short arm 34. Among them, the slider 32 may be fixedly connected to the spring long arm 31, so that the rotation angle of the spoiler net assembly 1 (which may also be referred to as the position of the spoiler net assembly 1 when in the unfolded state) can be defined by the included angle between the spring long arm 31 and the sliding direction on the slider 32. In one or more embodiments, the slider 32 and the spring long arm 31 may be integrally formed, such as by injection molding. Thus, the structural connection strength between the slider 32 and the spring long arm 31 can be improved. A sliding groove that slidably cooperates with the first skylight guide rail 52 or the second skylight guide rail 53 may be provided on the slider 32. Correspondingly, limit members for defining the sliding trajectory of the slider 32 may be respectively provided on the first skylight guide rail 52 and the second skylight guide rail 53. Among them, grease may be sprayed in the sliding groove to improve the smooth sliding of the grease.

[0051] One end of the spring helical section 33 is fixedly connected to the spring long arm 31, and the other end of the spring helical section 33 is fixedly connected to the spring short arm 34. For example, the spring short arm 34, the spring helical section 33, and the spring long arm 31 may be an integral structure. The spring short arm 34, the spring helical section 33, and the spring long arm 31 can all be made of spring steel material, and the outer surface of the support spring 3 is treated with black electrophoretic paint to enhance the overall texture. The slider 32 can be made of polyoxymethylene material, which can improve wear resistance and avoid frictional abnormal sounds generated when the slider 32 slides. The spring short arm 34 is embedded in the spring connection structure 2 to achieve the fixed connection between the support spring 3 and the spoiler net assembly 1. The spring helical section 33 forms an abutment with the spring connection structure 2, and the spring connection structure 2 can also limit the spring helical section 33. It can, while improving the structural connection strength between the support spring 3 and the spoiler net assembly 1, also disperse the deformation force of the spring helical section 33 through the abutting surface with the spring helical section 33, thereby improving the structural support strength and service life of the support spring 3.

[0052] After the skylight glass is closed, when the windshield net assembly is pressed and a pressing force is generated on the support spring 3, the spring helical section 33 deforms under the action of the pressing force, and transmits the deformation force to the spring connection structure 2 that limits the spring helical section 33 and the spring long arm 31 fixedly connected to the spring helical section 33 respectively. The spring long arm 31 deforms and can push the slider 32 to slide in a direction away from the front skylight cross beam 51.

[0053] After the skylight glass is opened and the pressing force of the windshield net assembly is cancelled, the spring long arm 31 and the spring helical section 33 return to their deformed states. The restoration of the deformation of the spring long arm 31 can push the slider 32 to slide in the direction close to the front crossbeam 51 of the skylight, thereby realizing the deployment of the windshield net assembly. Different parts of the support spring 3 can be respectively connected to the spoiler net assembly 1 and the skylight frame device 5, which can not only ensure the structural strength of the support spring 3 itself, but also improve the disassembly and assembly convenience of the support spring 3.

[0054] In an alternative embodiment of the invention, referring to Figure 2 , Figure 3 and Figure 5 As shown, the spring connection structure 2 includes a short arm limiting portion 21 and a helical limiting portion 22. A short arm limiting channel 2101 is provided on the short arm limiting portion 21, and the spring short arm 34 is embedded in the short arm limiting channel 2101. A helical limiting channel 2201 is provided on the helical limiting portion 22, and the helical limiting channel 2201 communicates with the short arm limiting channel 2101. Among them, the spring helical section 33 is adapted to the shape of the helical limiting channel 2201 to form the limitation of the spring helical section 33.

[0055] In the embodiment of the present invention, the spring connection structure 2 may include a short arm limiting portion 21 and a helical limiting portion 22. Among them, the short arm limiting portion 21 is used to fix the spring short arm 34, and the helical limiting portion 22 is used to limit the spring helical section 33. The spring short arm 34 can be embedded in the short arm limiting channel 2101. Among them, the short arm limiting channel 2101 can be used for the spring short arm 34 to be inserted, so as to realize the fixed connection between the support spring 3 and the spring connection structure 2. In some embodiments, the short arm limiting channel 2101 may be in the form of a groove with an opening or a blind hole, etc., and no more limitations are made here. A helical limiting channel 2201 is provided on the helical limiting portion 22, and the helical limiting channel 2201 communicates with the short arm limiting channel 2101. During the assembly process of the support spring 3, the spring helical portion can be matched with the shape of the helical limiting channel 2201, and then the spring short arm 34 is inserted into the short arm limiting channel 2101 from the helical limiting channel 2201, so that the connection between the support spring 3 and the spring connection structure 2 is completed. By limiting the spring short arm 34 through the short arm limiting portion 21 and limiting the spring helical section 33 through the thread limiting portion, the connection firmness between the support spring 3 and the spoiler net can be improved, and the disassembly and assembly convenience of the support spring 3 can be improved.

[0056] In an alternative embodiment of the invention, referring to Figure 5As shown, the spiral limiting part 22 includes a limiting body 221, a plurality of body support members 222 and a plurality of first support ribs 223. The plurality of body support members 222 are distributed on four sides of the end face of the limiting body 221 facing the spring spiral section 33 to cooperate with the limiting body 221 to form a limiting space for defining the position of the spring spiral section 33. The plurality of first support ribs 223 are spaced apart along the axial direction of the spring spiral section 33, and two adjacent first support ribs 223 form a spiral space that is in clearance fit with the spring coils in the spring spiral section 33. The limiting space and the spiral space cooperate to form the spiral limiting channel 2201, wherein the first support rib 223 is connected to the body support member 222.

[0057] In an embodiment of the present invention, the spiral limiting part 22, the short arm limiting part 21 and the spoiler net assembly 1 can be of an integral structure, so as to improve the connection structure strength between the spiral limiting part 22, the short arm limiting part 21 and the spoiler net assembly 1. The spiral limiting part 22 may include a limiting body 221, a plurality of body support members 222 and a plurality of first support ribs 223. Among them, the plurality of body support members 222 are distributed on four sides of the end face of the limiting body 221 facing the spring spiral section 33. In other words, the limiting body 221 and the plurality of body support members 222 are combined to form a limiting space that wraps the spring spiral section 33. Through this limiting space, the axial displacement and radial displacement of the spring spiral section 33 can be restricted.

[0058] The plurality of first support ribs 223 are spaced apart along the axial direction of the spring spiral section 33, and two adjacent first support ribs 223 with adjacent displacements form a spiral space that is in clearance fit with the spring coils in the spring spiral section 33. Among them, the spring spiral section 33 is formed by connecting a plurality of the spring coils end to end. That is to say, each spring coil can be embedded in the corresponding spiral space, so that each spring coil in the spring spiral section 33 can be limited through the spiral space, avoiding radial displacement and axial displacement of the spring coil. Thus, through the spiral limiting channel 2201 formed by the cooperation of the limiting space and the spiral space, the limiting firmness of the spring spiral section 33 can be greatly improved.

[0059] The deformation force generated by the spring helical segment 33 can be transmitted and dispersed from the spring helical segment 33 to the spring long arm 31, the first support rib 223, and the limit body 221. The force transmitted to the first support rib 223 can be further transmitted to the body support member 222 fixedly connected to the first support rib 223. Thus, the force received by the support spring 3 can be dispersed by the spiral limit portion 222, improving the deformation recovery performance of the support spring 3 and extending the service life of the support spring 3. At the same time, the support stability of the support spring 3 for the spoiler net assembly 1 during high-speed vehicle driving is improved.

[0060] The connection between the first support rib 223 and the body support member 222 can form a transmission path for the deformation force of the spring helical segment 33. When the support spring 3 deforms under the wind pressure when the spoiler net assembly 1 is in the deployed state, the spring short arm 34 receives a downward pressing force, and the slider 32 synchronously receives a downward pressing force. Among them, the upward anti-deformation force generated by the spring helical segment 33 abuts against the limit body 221. It can balance the forces received by the spring short arm 34 and the slider 32. Thus, the slider 32 does not slide, and the spring long arm 31 does not deform. At this time, the position of the spoiler net assembly 1 can be kept unchanged. Thus, through the reliable support of the support spring 3 for the spoiler net assembly 1, problems such as shaking or vibration of the spoiler net assembly 1 will not occur during rapid vehicle driving. Thereby, the risks of problems such as wind vibration, whistling, and abnormal noise that affect the driving experience during high-speed vehicle driving can be avoided.

[0061] In an alternative embodiment of the invention, referring to Figure 5 as shown, the end face of the limit body 221 facing the spring helical segment 33 is distributed in an uneven shape.

[0062] In the embodiment of the present invention, the uneven shape distribution can be understood as having a plurality of protrusions and a plurality of grooves provided on the surface of the limit body 221. Thus, through the spaced distribution of the protrusions and grooves, the structural strength of the limit body 221 can be improved, and it is convenient for the injection molding of the limit body 221. The uneven shape distribution can improve the injection molding performance of the limit body 221. In one or more embodiments, the protrusion can also be an integral structure with the first support rib 223. Thus, the elastic deformation force received by the spring helical segment 33 can be further dispersed.

[0063] In an alternative embodiment of the invention, referring to Figure 6 and Figure 7As shown, clamping joints 4 are respectively arranged on both sides of the spoiler net assembly 1, and the clamping joints 4 are engaged with the clamping holes formed in the skylight frame device 5 to form a rotational connection between the spoiler net assembly 1 and the skylight frame device 5.

[0064] In the embodiment of the present invention, through the clamping fit between the clamping joint 4 and the clamping hole, it is convenient to quickly disassemble and assemble the spoiler net assembly 1 from the skylight frame device 5. While simplifying the structure of the skylight spoiler device, it is beneficial to reduce the production cost of the skylight spoiler device.

[0065] In an optional embodiment of the invention, referring to Figure 7 As shown, the spoiler net assembly 1 includes a spoiler net body 11, a first side strip 12, a mesh cloth 13 and a second side strip 14. The first side strip 12 is fixedly connected to the spoiler net body 11. The mesh cloth 13 is fixedly connected to the first side strip 12, and the second side strip 14 is fixedly connected to the side of the mesh cloth 13 away from the first side strip 12. Among them, the second side strip 14 is fixedly connected to the skylight frame device 5. When the spring long arm 31 returns from the deformed state to the initial state, the spoiler net body 11 drives the first side strip 12 to move away from the skylight frame device 5, so that the mesh cloth 13 is unfolded.

[0066] In the embodiment of the present invention, the spoiler net assembly 1 may include a spoiler net body 11, a first side strip 12, a mesh cloth 13 and a second side strip 14. Among them, the first side strip 12 and the second side strip 14 may be distributed on the upper and lower sides of the mesh cloth 13. For example, the first side strip 12 and the mesh cloth 13 may be fixed by sewing. The second side strip 14 and the mesh cloth 13 may be fixed by sewing. When the air flow passes through the skylight assembly, the mesh cloth 13 can make the air flow pass through the mesh cloth 13 more evenly and dispersedly, thereby reducing the generation of turbulence and noise in the skylight assembly and improving the quiet comfort inside the vehicle body. Among them, the end face of the first side strip 12 away from the mesh cloth 13 is fixedly connected to the spoiler plate body, and the second side strip 14 is fixedly connected to the skylight frame device 5. That is to say, when the skylight glass of the skylight assembly is opened or retracted, the position of the second side strip 14 remains unchanged, and the first side strip 12 moves away from the second side strip 14 (which can also be called away from the skylight frame device 5) along with the spoiler net body 11, so as to drive the folded mesh cloth 13 to unfold. When the spring long arm 31 returns from the deformed state to the initial state (i.e., the state without deformation), the mesh cloth 13 is completely unfolded, so as to structurally support the spoiler net body 11 through the spring long arm 31. The structure of the above spoiler net assembly 1 is simple and the assembly is convenient, which can reduce the production cost and subsequent maintenance cost of the skylight spoiler device.

[0067] In some embodiments, both ends of the spoiler net body 11 may extend above the first skylight guide rail 52 and the second skylight guide rail 53 respectively. And the clamping joint 4 is arranged on the spoiler net body 11, so as to realize the rotational connection between the spoiler net body 11 and the skylight frame device 5.

[0068] In an alternative embodiment of the invention, the first side strip 12 is clamped with the spoiler net body 11; and / or, the second side strip 14 is clamped with the skylight frame device 5.

[0069] In the embodiment of the present invention, a first card slot may be provided on the end face of the spoiler net body 11 facing the first side strip 12, and the first side strip 12 and the first card slot are in shape fit to form the clamping connection between the first side strip 12 and the spoiler net body 11. Or, a second card slot may be provided on the end face of the skylight frame device 5 facing the second side strip 14, and the second side strip 14 and the second card slot are in shape fit to form the clamping connection between the second side strip 14 and the skylight frame device 5. Or, a first card slot may be provided on the end face of the spoiler net body 11 facing the first side strip 12, and the first side strip 12 and the first card slot are in shape fit to form the clamping connection between the first side strip 12 and the spoiler net body 11. And, a second card slot may be provided on the end face of the skylight frame device 5 facing the second side strip 14, and the second side strip 14 and the second card slot are in shape fit to form the clamping connection between the second side strip 14 and the skylight frame device 5.

[0070] In one or more embodiments, the first side strip 12 and the second side strip 14 may be made of a soft rubber material. For example, the soft rubber material may include plastic, rubber, silicone, etc., so that while ensuring that it can be fixed to the mesh cloth 13 by stitching, it can also form a clamping connection with the spoiler net body 11 and the skylight frame device 5. The clamping connection mode between the first side strip 12 and the spoiler net body 11 and the clamping connection mode between the second side strip 14 and the skylight frame device 5 can improve the disassembly and assembly convenience of the spoiler net assembly 1. For example, it can facilitate the replacement and cleaning of the mesh cloth 13. In addition, the structure of the skylight spoiler device can be simplified, which is beneficial to reducing the production cost of the skylight spoiler device.

[0071] In the embodiment of the present invention, the structural design of the skylight spoiler device can eliminate the need for other fasteners and auxiliary fixing parts / tools during the assembly process of each component of the skylight spoiler device, which can not only improve the assembly efficiency of the skylight spoiler device, but also reduce the production cost of the skylight spoiler device.

[0072] An embodiment of the present invention further provides a sunroof assembly, and the sunroof assembly may include the sunroof spoiler device described in any one of the above-mentioned invention embodiments.

[0073] In an embodiment of the present invention, for the sunroof assembly having the sunroof spoiler device described in any one of the above-mentioned invention embodiments, when the sunroof glass is opened, the deformation recovery ability of the spring long arm 31 of the support spring 3 can be used to drive the spoiler net assembly 1 to expand, and the pressure received by the spoiler net assembly 1 during high-speed driving can be buffered by the deformation of the support spring 3. Thus, while ensuring the structural stability of the spoiler net assembly 1, the situation where the spoiler net assembly 1 generates oscillating motion under the influence of air flow, resulting in an increase in in-vehicle wind noise or an aggravation of vibration phenomena, etc., can be alleviated.

[0074] An embodiment of the present invention further provides a vehicle, and the vehicle may include the sunroof assembly described in the above-mentioned invention embodiment.

[0075] In an embodiment of the present invention, the vehicle may include, but is not limited to, the following power types: fuel vehicles, electric vehicles, hybrid vehicles, fuel cell vehicles, etc. For the vehicle having the sunroof assembly described in the above-mentioned invention embodiment, when the sunroof glass is opened, the deformation recovery ability of the spring long arm 31 of the support spring 3 can be used to drive the spoiler net assembly 1 to expand, and the pressure received by the spoiler net assembly 1 during high-speed driving can be buffered by the deformation of the support spring 3. Thus, while ensuring the structural stability of the spoiler net assembly 1, the situation where the spoiler net assembly 1 generates oscillating motion under the influence of air flow, resulting in an increase in in-vehicle wind noise or an aggravation of vibration phenomena, etc., can be alleviated.

[0076] In summary, the embodiments of the present invention disclose a skylight spoiler device, a skylight assembly, and a vehicle. The embodiments of the present invention may include a spoiler net assembly 1, at least two spring connection structures 2, and at least two support springs 3. The spoiler net assembly 1 is rotatably connected to the skylight frame device 5 of the skylight assembly. At least two of the spring connection structures 2 are distributed at both ends of the spoiler net assembly 1. One end of each support spring 3 is connected to the corresponding spring connection structure 2, and the other end of the support spring 3 is slidably connected to the skylight frame device 5. The support spring 3 includes a spring long arm 31. When the spring long arm 31 is in a deformed state, it retracts the spoiler net assembly 1. When the spoiler net assembly 1 is deployed, the spring long arm 31 returns from the deformed state to the initial state, and the support spring 3 in the initial state forms a limit for the spoiler net assembly 1. Thus, when the skylight glass is opened, the deployment of the spoiler net assembly 1 can be driven by the deformation recovery ability of the spring long arm 31 of the support spring 3, and the pressure received by the spoiler net assembly 1 during high-speed driving can be buffered by the deformation of the support spring 3. Thereby, while ensuring the structural stability of the spoiler net assembly 1, the situation that the spoiler net assembly 1 generates oscillating motion under the influence of air flow, resulting in an increase in in-vehicle wind noise or an aggravation of the vibration phenomenon, can be alleviated.
