Sunroof beam, sunroof assembly and vehicle

[0001] Related applications

[0002] This disclosure claims priority to the Chinese invention patent application with application number 202311121969.X filed on September 1, 2023, and cites the entire contents of the above patent application disclosure as part of this disclosure. Technical Field

[0003] The present disclosure relates to the technical field of automobile sunroofs, and in particular to a sunroof crossbeam, a sunroof assembly and a vehicle. Background Art

[0004] Installed on the roof of a car, a car sunroof effectively circulates air inside the car, allowing fresh air to enter the car, bringing health and comfort to the driver and passengers. In addition, a car sunroof can also broaden the field of vision, meeting the needs of mobile photography and videography.

[0005] The aforementioned sunroof opening function is primarily achieved by a motor-driven drive chain mounted on the sunroof beam, which moves the glass. Furthermore, sunshades are typically installed on sunroofs, and their opening and closing are also primarily achieved through this method. However, the operation of the drive chain on the sunroof beam requires a pipe with a matching diameter. The operation of the drive chain dictates that the pipe must be in a curved state.

[0006] In the prior art, multiple metal pipes are typically fixed to the front crossbeam to enable the operation of the transmission chain. For example, as shown in Figures 1 and 2, the metal pipes are used to form a drive channel by setting multiple drive pipe brackets on the front crossbeam to position the transmission chain.

[0007] Since the above-mentioned arrangement of multiple metal pipes requires multiple assembly parts (such as drive pipe brackets) for positioning 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 the above-mentioned drive pipe bracket will make the process complicated and the cost further increased.

[0008] To overcome the aforementioned issues, a sunroof front crossbeam structure has been proposed in the prior art. This sunroof front crossbeam 1 is a vertically intersecting structure. As shown in Figures 3 and 4 , this sunroof front crossbeam 1 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 upper and lower covers 12, 11.

[0009] After analyzing the above-mentioned skylight front crossbeam structure, the inventors found that the above-mentioned skylight front crossbeam structure still has the following disadvantages:

[0010] The use of a top-to-bottom cross-section structure makes it difficult to ensure mold structural strength, resulting in a weak overall mold structure. The drive chain 4 is easily stuck during installation, making installation difficult. With a top-to-bottom cross-section structure, the upper and lower covers 12 and 11 are alternately positioned, making it impossible to detect the complete circular size during testing, making testing complex and inaccurate.

[0011] Therefore, it is necessary to provide a skylight crossbeam to solve at least one of the above problems.

[0012] Summary of the Invention

[0013] In response to the defects of the existing technology, the embodiments of the present disclosure provide a sunroof beam, a sunroof assembly and a vehicle, which can simplify the process and structure, reduce costs, improve mold strength, facilitate the installation of transmission parts, and also improve the accuracy of detection.

[0052] The technical solutions of the present disclosure 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 disclosure and are not used to limit the scope of the present disclosure. After reading the present disclosure, modifications of various equivalent forms of the present disclosure by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0053] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be an element centered thereon. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an element centered thereon. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this disclosure are for illustrative purposes only and do not represent the only implementation methods.

[0054] Unless otherwise defined, all technical and scientific terms used in this disclosure have the same meanings as those commonly understood by those skilled in the art to which this application belongs. The terms used in this disclosure and in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" as used in this disclosure includes any and all combinations of one or more of the relevant listed items.

[0055] The present disclosure 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 parts, and also improve detection accuracy.

[0056] Please refer to Figures 5, 6, 7, 12 and 13 as a whole. A skylight beam 100 is provided in the embodiment of the present application specification. The skylight beam 100 may include: a beam body 110 that is overall plate-shaped, and a limiting structure for accommodating a transmission component is provided in the beam body 110 in an integrally formed manner. The limiting structure includes: a first limiting portion 111 that passes through along a preset extension direction; a second limiting portion 112 that is spaced apart along the preset extension direction; and a third limiting portion 113 that is spaced apart along the preset extension direction. The first limiting portion 111, the second limiting portion 112 and the third limiting portion 113 cooperate to form a drive channel 101 for passing the transmission component.

[0057] In the embodiment of the present application specification, a sunroof crossbeam 100 is provided, wherein the sunroof crossbeam 100 has a plate-shaped crossbeam body 110, and a limiting structure is provided in the crossbeam body 110 at a predetermined position, for example, near the edge of the crossbeam body 110, by an integral molding method, and the limiting structure is used to accommodate a transmission assembly. 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 and is not limited to the above description. Technicians in the relevant field may make other changes based on the technical essence of the present application, but as long as the functions and effects achieved are the same or similar to those of the present application, they should be included in the scope of protection of the present application.

[0058] The transmission assembly is specifically configured to be connected to the drive unit 20 and to be driven by the drive unit 20. For example, in the embodiments and drawings of this application, the transmission assembly is mainly explained using the inner and outer mounted drive flexible shaft 82 and drive hose 81 as an example. Other transmission assembly methods, such as a flexible transmission chain, can be adaptively replaced with reference to this application.

[0059] The limiting mechanism is used to form a drive channel 101 that constrains the transmission assembly. The limiting mechanism may include a first limiting portion 111, a second limiting portion 112, and a third limiting portion 113. The first limiting portion 111, the second limiting portion 112, and the third limiting portion 113 cooperate to form the drive channel 101 for passing the transmission assembly.

[0060] In the implementation manner of the present application, since the limiting structure including the first limiting portion 111, the second limiting portion 112 and the third limiting portion 113 is provided with a driving channel 101, and the limiting structure is integrally formed with the beam body 110, compared with the prior art, there is no need to use additional metal channels and driving tube brackets, thereby reducing costs and simplifying the structure and process.

[0061] In addition, the limiting mechanism provided in the present application has a first limiting portion 111 that is arranged to pass through along a preset extension direction, which can improve the mold strength during the product injection molding process. When the transmission component is being installed, it can move along the first limiting portion 111, which is convenient for installation and is not prone to up and down deviation.

[0062] Please refer to Figures 14 and 15 in combination. Compared with the upper and lower through-hole structure used in the prior art, since the first limiting portion 111 is set to pass through along the predetermined extension direction, the mold strength of the skylight beam provided by the present application is also higher than that of the existing upper and lower through-hole structure during production.

[0063] As shown in Figure 14, in the upper and lower through-hole structure, the upper and lower covers are relatively independent, and there is no connection between the 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 upper and lower mold openings of the mold are spaced apart and form bosses. The strength of the raised parts of the bosses is relatively weak.

[0064] In this application, the bosses are connected, and the connection structure between the multiple bosses forms a whole. In the specific injection molding process, when the upper mold U and the lower mold D are performing processes such as demolding, the bosses are strong and not easily damaged.

[0065] The predetermined extension direction in the embodiments of the present disclosure may specifically be the extension direction of the limiting mechanism (drive channel 101), i.e., the arrangement direction of the transmission assembly. This predetermined extension direction may be determined based on the overall local outer contour of the crossbeam body 110. Of course, this predetermined extension direction may be adaptively adjusted based on the structure of the crossbeam body 110, the limiting mechanism, and the arrangement of other components on the crossbeam body 110, and this disclosure does not impose any specific limitations thereon.

[0066] Please refer to Figures 7, 8 and 9 in combination. In one embodiment, along the preset extension direction, that is, the extension direction of the drive channel 101, at least a portion of the second limiting portion 112 and at least a portion of the third limiting portion 113 can be located on the same cross-section of the drive channel 101.

[0067] In this embodiment, the second limiting portion 112 and the third limiting portion 113 are spaced apart along the preset extension direction. Taking a certain interval period as an example, along the preset extension direction, the second limiting portion 112 and the third limiting portion 113 can at least partially be located 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 first limiting portion 111 that is provided through the drive channel 101 can be simultaneously intercepted, 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.

[0068] As shown in Figures 8 and 9, further, on the cross-section of the driving channel 101, the first limiting portion 111, the second limiting portion 112 and the third limiting portion 113 are located at three different non-collinear positions, and the first limiting portion 111, the second limiting portion 112 and the third limiting portion 113 cooperate with the transmission assembly to form a closed detection circle S.

[0069] As shown in Figures 8 and 9, in this embodiment, the first stopper 111, the second stopper 112, and the third stopper 113 are located at three different, non-collinear positions on the cross section of the drive channel 101. The first stopper 111, the second stopper 112, and the third stopper 113, in conjunction with the transmission assembly, form a closed detection circle S. Subsequently, by measuring the positions of the three stoppers, the mating dimensions of the product (i.e., the outer diameter of the transmission assembly) can be accurately measured.

[0070] As shown in Figure 11, compared to existing top-to-bottom through-hole structures, this structure has a semicircular upper / lower cover. During specific testing, only the semicircle size of approximately φ5.4 can be detected, and the size of the entire circle cannot be fully measured. The subsequent use of this semicircle size to determine the matching size of the product P here is less accurate.

[0071] As shown in FIG. 8 , 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 portion 111 is located on the first side 121 , and the second limiting portion 112 and the third limiting portion 113 are located on the second side 122 .

[0072] The first limiting portion 111 is located on different sides from the second limiting portion 112 and the third limiting portion 113. Based on the installation position of the sunroof crossbeam, the first side 121 where the first limiting portion 111 is located is the relative lower side, and the second side 122 is the relative upper side.

[0073] In this embodiment, the second limiting portion 112 and the third limiting portion 113 are located on the same side of the beam body 110. Specifically, they can be claw structures arranged in pairs. Of course, the specific forms of the second limiting portion 112 and the third limiting portion 113 are not limited to the above examples. In the embodiments and drawings disclosed in this disclosure, they are mainly illustrated in the form of claws.

[0074] The second limiting portion 112 and the third limiting portion 113 are located on both sides of the first limiting portion 111 of the crossbeam body 110. The first limiting portion 111, which is located on the bottom side and is through-through, reliably supports the assembly and movement of the transmission assembly, while the second limiting portion 112 and the third limiting portion 113 reliably limit the transmission assembly. The three, in combination, form the drive channel 101, which not only has a simple structure, but also reduces costs and improves mold strength.

[0075] As shown in Figure 10 , the beam body 110 specifically has a first surface 1101 and a second surface 1102 that are opposed to each other along the thickness direction. The retaining structure further includes support portions 114 for connecting the first retaining portion 111 with the first surface 1101. The support portions 114 are spaced apart along a predetermined extension direction. It should be understood that the first surface 1101 is the surface of the first side 121 of the beam body 110, and the second surface 1102 is the surface of the second side 122 of the beam body 110.

[0076] In this embodiment, the limiting structure further includes a support portion 114 connecting the first limiting portion 111 with the first surface 1101. In addition to connecting the first limiting portion 111 with the first surface 1101, the support portion 114 also supports the transmission assembly.

[0077] The support portions 114 are arranged at intervals along the predetermined extension direction (ie, the driving channel 101 ). Specifically, along the predetermined extension direction, the support portions 114 are staggered with the second limiting portion 112 and the third limiting portion 113 .

[0078] Specifically, along a predetermined extension direction, the support portion 114 and the second limiting portion 112 and the third limiting portion 113 can be sequentially spaced apart. During production, the support portion 114, the first limiting portion 111, the second limiting portion 112, and the third limiting portion 113 can be injection molded using a pair of an upper mold (U) and a lower mold (D) having a predetermined structure.

[0079] Since the drive channel 101 is used to mate with the transmission assembly, which typically has a circular cross-sectional shape, the support portion 114 has a first mating surface 1140 for better mating with the transmission assembly. The first mating surface 1140 is a circular arc surface. Furthermore, when the surface that mates with the transmission assembly is a circular arc surface, it also facilitates smooth operation of the transmission assembly within the limiting structure.

[0080] Furthermore, the first position-limiting portion 111 may include a support bar disposed between two adjacent support portions 114. Along the extension direction of the drive channel 101, at locations where no support portion 114 is provided, the first position-limiting portion 111 may be a local structure within the support portion 114. In other words, at locations where no support portion 114 is provided, the support bar included in the first position-limiting portion 111 may be equivalent to a portion of the support portion 114, which together with another portion that mates with the transmission assembly constitutes the support portion 114.

[0081] The length of the support bar in the predetermined extension direction can be the same as the length of the second limiting portion 112 and the third limiting portion 113 in the predetermined extension direction. The cross-section of the support bar in the drive channel 101 can be roughly trapezoidal in shape, with this trapezoidal shape primarily intended to facilitate mold opening during injection molding. The surface of the support bar facing the transmission assembly can also be an arcuate surface, with the curvature of this arcuate surface consistent with the curvature of the arcuate surface of the support portion 114.

[0082] As shown in FIG8 , in one embodiment, the second stopper 112 has a second arcuate mating surface 1120 for mating with the transmission assembly. The third stopper 113 has a third arcuate mating surface 1130 for mating with the transmission assembly.

[0083] Since the drive channel 101 is used to cooperate with the transmission assembly, and the cross-sectional shape of the transmission assembly is usually circular. In order to better match the transmission assembly, the surfaces of the second limiting portion 112 and the third limiting portion 113 facing the transmission assembly can be arc surfaces. The second limiting portion 112, the third limiting portion 113 and the first limiting portion 111 cooperate with each other to form a relationship of fitting with the transmission assembly or a small gap fit. Among them, the second limiting portion 112 and the third limiting portion 113 in the position where they are not matched with the transmission assembly can be of any structure, in principle, as long as the current injection molding process can achieve it.

[0084] In a cross section of the drive channel 101, the second limiting portion 112 and the third limiting portion 113 are located on either side of the transmission assembly, respectively, and are separated by a predetermined distance. The first limiting portion 111 has a predetermined width. The predetermined distance is greater than the predetermined width and less than the outer diameter of the transmission assembly.

[0085] After the transmission assembly is positioned within the drive channel 101, it is necessary to ensure that the transmission assembly can be reliably restrained 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. In addition, considering the reasonable placement 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.

[0086] In a specific embodiment, the second limiting portion 112 and the third limiting portion 113 are a pair of claws arranged on the second surface 1102. The second limiting portion 112 and the third limiting portion 113 can be symmetrical structures. Taking one of the claws as an example, the claw can be the structure shown in the figure, and on the BB cross section of the drive channel 101, it includes: a circular arc surface facing the transmission component, and two mutually perpendicular planes opposite to the circular arc surface. Of course, the two mutually perpendicular planes can also be replaced by a single circular arc surface. Overall, the basic structure of the second limiting portion 112 and the third limiting portion 113 only needs to ensure that it has sufficient strength and can limit the transmission component under the premise of meeting the requirements of injection molding. Its specific shape, structure and size are not specifically required by this disclosure. Those skilled in the art may make other changes based on the technical essence of this disclosure. However, as long as the functions and effects achieved are the same or similar to those of this disclosure, they should be included in the scope of protection of this disclosure.

[0087] A sunroof assembly is also provided in an embodiment of the present disclosure, and the sunroof assembly includes the above-mentioned sunroof beam 100. The sunroof assembly can achieve the technical effect achieved by the above-mentioned sunroof beam 100 embodiment by setting the sunroof beam 100. For details, please refer to the specific description of the above-mentioned embodiment, and the present disclosure will not repeat them here.

[0088] In one embodiment, the sunroof assembly may further include a transmission assembly disposed within the drive channel 101 and a drive unit 20 configured to drive the transmission assembly. Furthermore, the sunroof assembly may further include a pull rod 50 and a sunshade 60. The pull rod 50 is connected to the transmission assembly and can be driven by the transmission assembly to open and close the sunshade 60.

[0089] Specifically, the driving unit 20 is mainly used to provide driving force for opening and closing the sunshade 60. Specifically, the driving unit 20 can be in the form of an electric motor, etc. In the specification of the present disclosure, the driving unit 20 is illustrated by taking a driving motor as an example.

[0090] The transmission assembly is mainly used to transmit 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 flexible shaft 82. The drive hose 81 is arranged in the drive channel 101. The drive flexible shaft 82 is arranged in the drive hose 81. One end of the drive flexible shaft 82 is connected to the pull rod 50. The drive flexible shaft 82 runs in the drive hose 81. The drive hose 81 is installed in the drive channel 101. The drive channel 101 restricts the drive hose 81 from shaking.

[0091] During use, the driving motor drives the driving flexible shaft 82 to operate, and the driving flexible shaft 82 drives the pull rod 50 of the sunshade curtain 60 to move, thereby realizing the opening and closing of the sunshade curtain 60.

[0092] A vehicle is also provided in an embodiment of the present disclosure, and the vehicle includes the above-mentioned sunroof assembly provided with the sunroof cross beam 100. The vehicle can achieve the technical effect achieved by the above-mentioned sunroof cross beam 100 embodiment by providing the sunroof assembly provided with the sunroof cross beam 100. For details, please refer to the specific description of the above-mentioned embodiment, and the present disclosure will not repeat them here.

There is no order of precedence between the two, nor should they be understood to indicate or imply relative importance. Furthermore, in the description of this disclosure, unless otherwise specified, "plurality" means two or more.

[0094] The above-mentioned various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.
