Description

Technical Field

[0001] This invention relates to the field of automotive sunroof technology, and particularly to a sunroof crossbeam, sunroof assembly, and vehicle. Background Technology

[0002] A car sunroof, installed on the roof, effectively improves air circulation inside the vehicle, increasing the amount of fresh air entering and providing a healthy and comfortable experience for passengers. Furthermore, a sunroof can also expand the field of vision, meeting the needs of mobile photography and videography.

[0003] The sunroof's opening function is primarily achieved by a drive chain mounted on the sunroof's crossbeam, which, driven by a motor, moves the glass. Additionally, sunroofs typically have sunshades, which are also opened and closed using the same method. However, the drive chain on the sunroof's crossbeam requires a pipe with a matching diameter. The operation of the drive chain dictates that the matching pipe must be in a bent state.

[0004] In existing technologies, multiple metal tubing components are typically fixed to the front crossbeam to enable the operation of the drivetrain. For example, ... Figure 1 and Figure 2 As shown, the metal fittings form a drive channel by setting multiple drive tube supports on the front crossbeam to position the transmission chain.

[0005] Because setting up multiple metal pipes requires multiple assembly parts (such as drive pipe brackets) to position these metal pipes, it is difficult to achieve the requirements of minimizing the number of parts and minimizing costs. Moreover, the need to add two assembly parts such as drive pipe brackets will lead to complex processes and further increase costs.

[0006] To overcome the above problems, a new skylight front beam structure has been proposed in the prior art. This skylight front beam 1 is a vertically through-beam structure. For example... Figure 3 and Figure 4 As shown, the front crossbeam 1 of the sunroof is provided with two transmission chain channels consisting of multiple upper covers 12 and multiple lower covers 11, with the upper covers 12 and lower covers 11 arranged alternately. The transmission chain 4 runs within the transmission chain channels formed by the cooperation of the upper covers 12 and lower covers 11.

[0007] After analyzing the above-mentioned skylight front beam structure, the inventors found that the above-mentioned skylight front beam structure still has the following drawbacks:

[0008] The use of a through-hole structure makes it difficult to guarantee the strength of the mold structure, resulting in a relatively weak overall mold structure. Furthermore, the through-hole structure makes it easy for the transmission chain 4 to get stuck during installation, making it difficult to install. With the upper cover 12 and lower cover 11 alternating in the through-hole structure, the complete circular dimension cannot be detected during inspection, making the inspection complex and inaccurate.

[0009] Therefore, it is necessary to propose a skylight beam to solve at least one of the above problems. Summary of the Invention

[0010] To address the shortcomings of existing technologies, this invention provides a sunroof crossbeam, a sunroof assembly, and a vehicle, which simplifies the process and structure, reduces costs, improves mold strength, facilitates the installation of transmission components, and also improves the accuracy of testing.

[0011] The specific technical solution of the embodiments of the present invention is as follows:

[0012] A sunroof crossbeam includes a crossbeam body that is integrally plate-shaped. The crossbeam body has an integrally formed limiting structure for accommodating a transmission component. The limiting structure includes: a first limiting portion extending through a predetermined direction; a second limiting portion spaced apart along the predetermined extension direction; and a third limiting portion spaced apart along the predetermined extension direction. The first, second, and third limiting portions cooperate to form a drive channel for the transmission component to pass through.

[0013] In a preferred embodiment, the second limiting portion and the third limiting portion are at least partially located on the same cross section of the drive channel along the preset extension direction.

[0014] In a preferred embodiment, on the cross-section of the drive channel, the first limiting part, the second limiting part, and the third limiting part are located at three different non-collinear positions, and the three parts of the first limiting part, the second limiting part, and the third limiting part, which cooperate with the transmission assembly, can form a closed detection circle.

[0015] In a preferred embodiment, the beam body has a first side and a second side opposite to each other along the thickness direction, the first limiting part is located on the first side, and the second limiting part and the third limiting part are located on the second side.

[0016] In a preferred embodiment, the beam body has a first surface and a second surface opposite each other along the thickness direction, and the limiting structure further includes a support portion for connecting the first limiting portion and the first surface, the support portion being spaced apart along the preset extension direction.

[0017] In a preferred embodiment, the support portion is offset from the second limiting portion and the third limiting portion along the preset extension direction.

[0018] In a preferred embodiment, the support portion has a first mating surface that mates with the transmission assembly, and the first mating surface is an arc surface.

[0019] In a preferred embodiment, the first limiting portion includes a support strip disposed between two adjacent support portions.

[0020] In a preferred embodiment, the second limiting portion has a second mating surface that cooperates with the transmission assembly, and the second mating surface is an arc surface.

[0021] In a preferred embodiment, the third limiting portion has a third mating surface that cooperates with the transmission assembly, and the third mating surface is an arc surface.

[0022] In a preferred embodiment, on the cross-section of the drive channel, the second limiting portion and the third limiting portion are respectively located on both sides of the transmission assembly, and the second limiting portion and the third limiting portion are separated by a predetermined distance. The first limiting portion has a predetermined width, and the predetermined distance is greater than the predetermined width and less than the outer diameter of the transmission assembly.

[0023] In a preferred embodiment, the second limiting part and the third limiting part are a pair of claws disposed on the second surface.

[0024] A sunroof assembly, the sunroof assembly including any of the sunroof crossbeams described above.

[0025] In a preferred embodiment, the sunroof assembly further includes: a transmission assembly disposed within the drive channel; and a drive unit for driving the transmission assembly.

[0026] In a preferred embodiment, the sunroof assembly further includes a pull rod and a sunshade, wherein the pull rod is connected to the transmission assembly and can be driven by the transmission assembly to open and close the sunshade.

[0027] In a preferred embodiment, the transmission assembly includes a drive hose and a drive flexible shaft, the drive hose passing through the drive channel, the drive flexible shaft passing through the drive hose, and one end of the drive flexible shaft being connected to the pull rod.

[0029] The technical solution of the present invention has the following significant beneficial effects:

[0030] In the embodiments described in this application, the sunroof beam has a driving channel formed by a limiting structure with a first limiting part, a second limiting part and a third limiting part, and the limiting structure is integrally formed with the beam body. Compared with the prior art, it is not necessary to use an additional metal channel and driving tube support, which reduces costs and simplifies the structure and process.

[0031] Furthermore, the limiting mechanism for the sunroof beam provided in this application has a first limiting part that extends through the product along a preset extension direction. This can improve the strength of the mold during the product injection molding process. When the transmission component is installed, it can move along the first limiting part, making installation convenient and preventing vertical displacement.

[0075] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art fall within the scope defined by the appended claims.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0077] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0078] This invention provides a sunroof crossbeam, a sunroof assembly, and a vehicle, which can simplify the process and structure, reduce costs, improve mold strength, facilitate the installation of transmission components, and also improve the accuracy of testing.

[0079] Please refer to the following for comprehensive information. Figure 5 , Figure 6 , Figure 7 , Figure 12 and Figure 13 This application specification provides a sunroof crossbeam 100, which may include: a crossbeam body 110 that is generally plate-shaped, wherein the crossbeam body 110 is integrally formed with a limiting structure for accommodating a transmission component, the limiting structure including: a first limiting part 111 that extends through along a preset extension direction; a second limiting part 112 that is spaced apart along the preset extension direction; and a third limiting part 113 that is spaced apart along the preset extension direction; the first limiting part 111, the second limiting part 112 and the third limiting part 113 cooperate to form a drive channel 101 for the transmission component to pass through.

[0080] This application provides a sunroof crossbeam 100, which has a plate-shaped crossbeam body 110. A limiting structure is integrally formed at a predetermined position on the crossbeam body 110, for example, near the edge of the crossbeam body 110. This limiting structure is used to accommodate a transmission component. Specifically, the crossbeam body 110 and the limiting structure can be injection molded from plastic particles. Of course, the integral molding method can also be other methods, not limited to the above description. Those skilled in the art, inspired by the technical essence of this application, may make other modifications, but as long as the achieved function and effect are the same as or similar to that of this application, they should be covered within the scope of protection of this application.

[0081] This transmission component is specifically used to connect with the drive unit 20 and can be driven by the drive unit 20 to operate. For example, in the embodiments and drawings of this application, this transmission component is mainly explained using the inner and outer drive flexible shaft 82 and drive hose 81 as examples. Other transmission components, such as flexible transmission chains, can be adapted to this application.

[0082] The limiting mechanism is used to form a drive channel 101 that constrains the transmission assembly. The limiting mechanism may include a first limiting part 111, a second limiting part 112, and a third limiting part 113. The first limiting part 111, the second limiting part 112, and the third limiting part 113 cooperate to form a drive channel 101 for the transmission assembly to pass through.

[0083] In the embodiments described in this application, since the limiting structure provided with the first limiting part 111, the second limiting part 112 and the third limiting part 113 forms a driving channel 101, and the limiting structure is integrally formed with the crossbeam body 110, compared with the prior art, it is not necessary to use an additional metal channel and driving tube support, which reduces costs and simplifies the structure and process.

[0084] Furthermore, the limiting mechanism provided in this application has a first limiting part 111 that is provided through along a preset extension direction. During the product injection molding process, it can improve the mold strength. When the transmission component is installed, it can move along the first limiting part 111, making installation convenient and preventing vertical displacement.

[0085] Please refer to the following: Figure 14 and Figure 15 Compared with the existing technology that uses a through-hole structure, since the first limiting part 111 is through-hole along a predetermined extension direction, the mold strength of the skylight beam provided in this application is also higher than that of the existing through-hole structure.

[0086] like Figure 14 As shown, in the through-hole structure, the upper and lower covers are relatively independent, and there is no connection between two adjacent products P (i.e., the upper and lower covers). In a partial cross-sectional view along the extension direction of the drive channel 101, the mold openings are spaced out as one boss at a time. The strength of the raised part of this boss is relatively weak.

[0087] In this application, the bosses are connected, and the connection structure between multiple bosses forms a whole. During the injection molding process, the bosses have high strength and are not easily damaged when the upper mold U-shaped die and the lower mold D-shaped die are subjected to processes such as demolding.

[0088] In this embodiment, the predetermined extension direction can specifically be the extension direction of the limiting mechanism (drive channel 101), that is, the arrangement direction of the transmission components. The predetermined extension direction can be determined based on the partial outer contour structure of the beam body 110. Of course, the predetermined extension direction can be adaptively adjusted according to the different structures of the beam body 110, the limiting mechanism, and the arrangement of other components on the beam body 110. This application does not impose specific limitations on this.

[0089] Please refer to the following: Figure 7 , Figure 8 and Figure 9 In one embodiment, along the predetermined extension direction, i.e. the extension direction of the drive channel 101, the second limiting portion 112 and the third limiting portion 113 can be located at least partially on the same cross section of the drive channel 101.

[0090] In this embodiment, the second limiting portion 112 and the third limiting portion 113 are spaced apart along the preset extension direction. Specifically, along the preset extension direction, taking a certain interval as an example, the second limiting portion 112 and the third limiting portion 113 can at least partially lie on the same cross-section of the drive channel 101. That is, when a cross-section is made on the drive channel 101, the second limiting portion 112, the third limiting portion 113, and the through-connected first limiting portion 111 can be simultaneously captured, thereby reliably limiting the transmission assembly using the transmission channel formed by the first limiting portion 111, the second limiting portion 112, and the third limiting portion 113.

[0091] like Figure 9 As shown, further, on the cross-section of the drive channel 101, the first limiting part 111, the second limiting part 112 and the third limiting part 113 are located at three different non-collinear positions, and the three parts of the first limiting part 111, the second limiting part 112 and the third limiting part 113 that cooperate with the transmission assembly can form a closed detection circle S.

[0092] like Figure 8 and Figure 9 As shown, in this embodiment, on the cross-section of the drive channel 101, the first limiting part 111, the second limiting part 112, and the third limiting part 113 are located at three different, non-collinear positions. The three parts of the first limiting part 111, the second limiting part 112, and the third limiting part 113 that cooperate with the transmission assembly can form a closed detection circle S. Subsequently, by measuring the positions of the three limiting parts, the mating dimensions of the product (i.e., the outer diameter of the transmission assembly) can be accurately measured.

[0093] like Figure 11 As shown, compared to existing through-hole structures, the upper / lower covers of this structure are semi-circular. During actual testing, only the approximate size of this semi-circle, φ5.4, could be detected; the entire circle's size could not be measured. Therefore, the accuracy of using this semi-circle size to determine the fitting dimensions of product P at this location is low.

[0094] like Figure 8As shown, the beam body 110 has a first side 121 and a second side 122 opposite to each other along the thickness direction, the first limiting part 111 is located on the first side 121, and the second limiting part 112 and the third limiting part 113 are located on the second side 122.

[0095] The first limiting part 111 is located on a different side from the second limiting part 112 and the third limiting part 113. Based on the installation position of the sunroof beam, the first side 121 where the first limiting part 111 is located is the lower side, and the second side 122 is the upper side.

[0096] In this embodiment, the second limiting part 112 and the third limiting part 113 are located on the same side of the crossbeam body 110. Specifically, they can be a pair of claw structures. Of course, the specific forms of the second limiting part 112 and the third limiting part 113 are not limited to the above examples. In the embodiments and drawings of this application, the claw form is mainly used as an example for illustration.

[0097] The second limiting part 112 and the third limiting part 113 are located on both sides of the first limiting part 111 on the crossbeam body 110. The first limiting part 111, which is located on the bottom side, reliably supports the assembly and movement of the transmission component, and the second limiting part 112 and the third limiting part 113 reliably limit the transmission component. The drive channel 101 formed by the cooperation of the three is not only simple in structure, but also reduces costs and improves mold strength.

[0098] like Figure 10 As shown, specifically, the beam body 110 has a first surface and a second surface opposite to each other along the thickness direction, and the limiting structure further includes a support portion 114 for connecting the first limiting portion 111 and the first surface, the support portion 114 being spaced apart along the preset extension direction.

[0099] In this embodiment, the limiting structure further includes a support portion 114 that connects the first limiting portion 111 to the first surface. Besides connecting the first limiting portion 111 to the first surface, the support portion 114 also provides support for the transmission assembly.

[0100] The support portion 114 is provided at intervals along the aforementioned preset extension direction (i.e., drive channel 101). Specifically, along the preset extension direction, the support portion 114 is offset from the second limiting portion 112 and the third limiting portion 113.

[0101] Specifically, along a predetermined extension direction, the support portion 114, the second limiting portion 112, and the third limiting portion 113 can be sequentially spaced apart. In actual manufacturing, the support portion 114, the first limiting portion 111, the second limiting portion 112, and the third limiting portion 113 can be injection molded by pairing an upper mold U and a lower mold D with a predetermined structure.

[0102] Since the drive channel 101 is used to cooperate with the transmission assembly, and the cross-sectional shape of the transmission assembly is typically circular, the support portion 114 has a first mating surface 1140 that mates with the transmission assembly to better match the transmission assembly. This first mating surface 1140 is an arc surface. Furthermore, when the surface mating with the transmission assembly is an arc surface, it also facilitates the smooth operation of the transmission assembly within the limiting structure.

[0103] Furthermore, the first limiting portion 111 may include a support strip disposed between two adjacent support portions 114. Along the extending direction of the drive channel 101, in a position where no support portion 114 is provided, the first limiting portion 111 may be a partial structure within the support portion 114.

[0104] The length of the support bar in the predetermined extension direction can be the same as the lengths of the second limiting portion 112 and the third limiting portion 113 in the predetermined extension direction. The shape of the support bar in the cross-section of the drive channel 101 can be approximately trapezoidal, and the trapezoidal structure is mainly to meet the mold opening requirements during injection molding. The surface of the support bar facing the transmission assembly can also be an arc surface, and the curvature of the arc surface is consistent with the curvature of the arc surface of the support portion 114.

[0105] like Figure 8 As shown, in one embodiment, the second limiting portion 112 has a second mating surface 1120 that mates with the transmission assembly, and the second mating surface 1120 is an arc surface. The third limiting portion 113 has a third mating surface 1130 that mates with the transmission assembly, and the third mating surface 1130 is an arc surface.

[0106] Since the drive channel 101 is used to cooperate with the transmission component, and the cross-sectional shape of the transmission component is usually circular, the surfaces of the second limiting part 112 and the third limiting part 113 facing the transmission component can be arc surfaces for better matching with the transmission component. The second limiting part 112, the third limiting part 113 and the first limiting part 111 cooperate to form a close fit or a small clearance fit with the transmission component. Where the second limiting part 112 and the third limiting part 113 are not in cooperation with the transmission component, their structure can be arbitrary, as long as it is feasible by current injection molding processes.

[0107] On the cross-section of the drive channel 101, the second limiting part 112 and the third limiting part 113 are respectively located on both sides of the transmission assembly, and the second limiting part 112 and the third limiting part 113 are spaced apart by a predetermined distance. The first limiting part 111 has a predetermined width. The predetermined distance is greater than the predetermined width and less than the outer diameter of the transmission assembly.

[0108] Once the transmission assembly is installed within the drive channel 101, it is necessary to ensure that the transmission assembly can be reliably confined within the drive channel 101. To achieve this, the distance between the second limiting portion 112 and the third limiting portion 113 can be set to be smaller than the outer diameter of the transmission assembly. Furthermore, considering the reasonable arrangement of the mold during injection molding to ensure smooth mold demolding, the width of the first limiting portion 111 is smaller than the distance between the second limiting portion 112 and the third limiting portion 113.

[0109] In one specific embodiment, the second limiting part 112 and the third limiting part 113 are a pair of claws disposed on the second surface. The second limiting part 112 and the third limiting part 113 can be symmetrically structured. Taking one of the claws as an example, the claw can have the structure shown in the figure, including: an arc surface facing the transmission component and two mutually perpendicular planes opposite the arc surface on the BB section of the drive channel 101. Of course, the two mutually perpendicular planes can also be replaced by an arc surface. Overall, the basic structure of the second limiting part 112 and the third limiting part 113, under the premise of meeting the injection molding requirements, only needs to ensure sufficient strength and limit the transmission component. The specific shape, structure and size are not specifically required in this application. Those skilled in the art may make other changes under the inspiration of the technical essence of this application, but as long as the function and effect achieved are the same as or similar to this application, they should be covered within the protection scope of this application.

[0110] This application also provides a sunroof assembly, which includes the sunroof crossbeam 100 described above. By setting the sunroof crossbeam 100, the sunroof assembly can achieve the technical effects achieved by the above-described embodiment of the sunroof crossbeam 100. For details, please refer to the specific description of the above-described embodiment, which will not be repeated here.

[0111] In one embodiment, the sunroof assembly may further include: a transmission assembly passing through the drive channel 101; and a drive unit 20 for driving the transmission assembly. Additionally, the sunroof assembly may also include: a pull rod 50 and a sunshade 60, the pull rod 50 being connected to the transmission assembly and capable of being driven by the transmission assembly to open and close the sunshade 60.

[0112] Specifically, the drive unit 20 is mainly used to provide driving force for opening and closing the sunshade 60. Specifically, the drive unit 20 can be in the form of a motor, electric motor, etc. In this application's specification, the drive unit 20 is illustrated using a drive motor as an example.

[0113] The transmission assembly primarily transmits the driving force provided by the drive unit 20 to the sunshade 60. The transmission assembly may include a drive hose 81 and a drive shaft 82. The drive hose 81 passes through the drive channel 101, and the drive shaft 82 passes through the drive hose 81. One end of the drive shaft 82 is connected to the pull rod 50. The drive shaft 82 runs within the drive hose 81, which is installed in the drive channel 101, preventing the drive hose 81 from swaying.

[0114] In use, the drive motor drives the drive flexible shaft 82 to run, and the drive flexible shaft 82 drives the pull rod 50 of the sunshade curtain 60 to move, so as to open and close the sunshade curtain 60.

[0115] This application also provides a vehicle that includes the sunroof assembly with the sunroof beam 100 described above. By providing the sunroof assembly with the sunroof beam 100, the vehicle can achieve the technical effects achieved by the above-described embodiment of the sunroof beam 100. For details, please refer to the specific description of the above-described embodiment, which will not be repeated here.

Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more.
