Side roof lamp and vehicle roof mounting structure

Abstract

This utility model discloses a side dome light mounting structure for a vehicle roof, comprising: a side dome light mounting base, wherein the side dome light is fixedly connected to the roof via the side dome light mounting base; and a flexible connector, which is fixedly connected to both the roof and the side dome light, and is used to hang the side dome light on the roof when the side dome light mounting base is detached from the roof. In this side dome light mounting structure for a vehicle roof, if the side dome light mounting base is detached from the roof when the side curtain airbag ruptures, the side dome light will only be suspended on the roof due to the connection of the flexible connector, and will not fly out. This can effectively reduce the risk of the side dome light being thrown out by the side curtain airbag rupture, thereby meeting the safety requirements for vehicles equipped with side curtain airbags and panoramic sunroofs.

Description

Technical Field

[0001] This utility model relates to the field of vehicle structure design technology, specifically to a side roof light mounting structure for a vehicle roof. Background Technology

[0002] Some vehicle models have side dome lights installed along the side edge of the headliner for interior lighting. Previously, these side dome lights were typically fixed directly to the headliner using clips or adhesive. However, with increasing demands for vehicle safety, more and more models are equipped with side curtain airbags. In the current installation method, the side dome lights are easily detached from the headliner and ejected during a side curtain airbag explosion, potentially injuring occupants and failing to meet vehicle safety regulations. Current technology generally uses repositioning of the side dome lights to prevent impact from the side curtain airbags. However, for some models with panoramic sunroofs, the available space for side dome lights on the headliner is limited, making it impossible to completely avoid the impact of the side curtain airbags. Therefore, for panoramic sunroof models, the side dome lights near the side curtain airbags must be removed, significantly impacting the vehicle's functionality.

[0003] Therefore, how to improve the existing installation structure of the roof side lights and the roof to meet the safety requirements of vehicles equipped with side curtain airbags and panoramic sunroofs has become a technical problem that needs to be solved. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a side roof light mounting structure for a vehicle roof. In this side roof light mounting structure, the side roof light has good safety in use and can effectively reduce the risk of the side roof light being blown out by the side curtain airbag, thereby meeting the safety requirements of vehicles equipped with side curtain airbags and panoramic sunroofs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a side dome light mounting structure for a vehicle roof, comprising: a side dome light mounting base, wherein the side dome light is fixedly connected to the roof via the side dome light mounting base; and a flexible connector, which is fixedly connected to the roof and the side dome light respectively, for hanging the side dome light on the roof when the side dome light mounting base is detached from the roof.

[0006] Furthermore, the ceiling has a side ceiling light through hole, and the side ceiling light mounting base has a channel for installing the side ceiling light, the channel corresponding to the side ceiling light through hole; the side ceiling light mounting base and the ceiling are fixed together by heat fusion at the side ceiling light through hole.

[0007] Furthermore, an annular sealing strip is installed in the through hole of the side top light. The side of the sealing strip facing the side top light mounting base has a connecting ring extending into the channel. The end of the connecting ring facing the channel has a snap-fit ​​component and a heat-fused connector. The channel has a stepped surface that snaps into the snap-fit ​​component, and the heat-fused connector is heat-fused to the stepped surface. The light-emitting end of the side top light passes through the channel and extends to the sealing strip.

[0008] Furthermore, the ceiling includes a ceiling substrate layer and a ceiling frame connected to the ceiling substrate layer. The side ceiling light mounting base is fixed to the ceiling substrate layer, and the ceiling frame is located on the side of the ceiling substrate layer facing the side ceiling light mounting base. The flexible connector has a first connecting end and a second connecting end. The first connecting end is fixedly connected to the ceiling frame, and the second connecting end is fixedly connected to the side ceiling light.

[0009] Furthermore, the outer circumferential surface of the side ceiling light mounting base is provided with a connecting plate that abuts against and is fixed to the outer surface of the ceiling substrate layer; the mounting end of the side ceiling light is bolted to the connecting plate.

[0010] Furthermore, the roof also includes a skin layer connected to the roof substrate layer facing the interior of the vehicle; the side roof light through hole includes a first hole and a second hole, the first hole is formed in the skin layer, the second hole is formed in the roof substrate layer, the first hole and the second hole are coaxial, and the circumferential edge of the first hole is folded towards the second hole to form a flange.

[0011] Furthermore, the side light mounting base has an annular boss on the side facing the ceiling substrate layer, and the annular boss is engaged between the second hole and the flange.

[0012] Furthermore, the second hole has a positioning notch on its circumferential edge, and the annular boss has a positioning boss on its circumferential surface that engages with the positioning notch.

[0013] Furthermore, multiple snap-fit ​​components and hot-melt connectors are provided and are evenly arranged circumferentially along the end face of the sealing strip.

[0014] Furthermore, the flexible connector is an elastic band or an elastic rope.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The side dome light mounting structure provided by this utility model offers good safety for the side dome light, effectively reducing the risk of it being ejected due to the rupture of the side curtain airbag, thus meeting the safety requirements of vehicles equipped with side curtain airbags and panoramic sunroofs. Specifically, in this mounting structure, if the side dome light mounting bracket detaches from the roof during a side curtain airbag rupture, the flexible connector ensures the side dome light remains suspended on the roof and does not fly off. When the mounting bracket detaches, the impact force from the side curtain airbag is reduced, and the flexible connector only needs to prevent it from being detached by the light's inertia. Since the overall mass of the side dome light is not large, the flexible connector will not detach, effectively reducing the risk of the side dome light detaching from the roof. Furthermore, this mounting structure is simple and facilitates cost control.

Detailed Implementation

[0024] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only for illustrating the basic concept of this utility model. Unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0025] Please see Figure 1-5 This embodiment discloses a side dome light mounting structure for a vehicle roof, including a side dome light mounting base 3 and a flexible connector 4. The side dome light 2 is fixedly connected to the roof 1 via the side dome light mounting base 3. The flexible connector 4 is fixedly connected to both the roof 1 and the side dome light 3, and is used to hang the side dome light 2 on the roof 1 when the side dome light mounting base 3 is detached from the roof 1. The fixing method between the side dome light mounting base 3 and the roof 1 includes, but is not limited to, snap-fit, adhesive, or screw-fit, etc., and is not limited here. Similarly, the fixing method between the side dome light 2 and the side dome light mounting base 3 is not limited, such as screw-fit or snap-fit, etc. The flexible connector 4 can be a flexible strip or flexible rope, etc. In this embodiment, the flexible connector 4 is preferably an elastic flexible strip or flexible rope. Here, the fixing method between the flexible connector 4 and the roof 1 and the side dome light 2 is not limited, including but not limited to snap-fit, screw-fit, etc. It is understandable that, since the side ceiling light 2 is fixedly integrated with the side ceiling light mounting base 3 after assembly, in other embodiments, the flexible connector 4 can also be fixedly connected to the side ceiling light mounting base 3. The flexible connector 4 being fixedly connected to both the ceiling 1 and the side ceiling light 2 means that the flexible connector 4 establishes independent connection relationships with both the ceiling 1 and the side ceiling light 2. In this embodiment, there is one flexible connector 4; however, in other embodiments, multiple flexible connectors 4 can be used.

[0026] In the aforementioned side dome light and vehicle roof mounting structure, the side dome light 2 offers good safety, effectively reducing the risk of it being ejected due to the rupture of the side curtain airbag, thus meeting the safety requirements for vehicles equipped with side curtain airbags and panoramic sunroofs. Specifically, in this side dome light and vehicle roof mounting structure, when the side curtain airbag ruptures, if the fixed connection point between the side dome light mounting base 3 and the roof 1 detaches, the side dome light 2 will remain suspended on the roof 1 due to the connection provided by the flexible connector 4, and will not fly off. After the fixed connection point between the side dome light mounting base 3 and the roof 1 detaches, the impact force of the side dome light 2 from the side curtain airbag is reduced. The flexible connector 4 typically only needs to prevent it from being detached by the inertial force of the side dome light 2. Since the overall mass of the side dome light 2 is not large, the flexible connector 4 will not be detached, thus effectively reducing the risk of the side dome light 2 detaching from the roof 1 and flying off. In addition, the side dome light 2 is installed in the vehicle roof using a flexible connector 4 to improve the safety of its use. The overall structure is simple and conducive to cost control.

[0027] In this embodiment, the roof 1 has a side dome light through-hole 1a, and the side dome light mounting base 3 has a channel 3a for installing the side dome light 2, the channel 3a corresponding to the side dome light through-hole 1a; the side dome light mounting base 3 and the roof 1 are fixed together by heat fusion at the side dome light through-hole 1a. Specifically, the side dome light mounting base 3 is a cylindrical structure with both ends through, the inner hole of the cylindrical structure is the channel 3a, and the side dome light 2 is inserted into the channel 3a. The side dome light mounting base 3 is preferably made of plastic. The correspondence between the channel 3a and the side dome light through-hole 1a means that the center lines of the channel 3a and the side dome light through-hole 1a are aligned, thereby ensuring that the light emitted by the side dome light 2 can illuminate the vehicle interior through the side dome light through-hole 1a after the side dome light 2 is installed. The side ceiling light mounting base 3 and the ceiling 1 are fixed by heat fusion at the side ceiling light through hole 1a. By using heat fusion, the connection stability between the side ceiling light mounting base 3 and the ceiling 1 can be guaranteed. At the same time, the heat fusion method does not require threaded holes in the ceiling, and the space required for the connection part is small.

[0028] In this embodiment, an annular sealing strip 5 is installed in the side top light through hole 1a. The sealing strip 5 has a connecting ring 501 extending into the channel 3a on the side facing the side top light mounting base 3. The end of the connecting ring 501 facing the channel 3a has a snap-fit ​​component 502 and a heat-fused connector 503. The channel 3a has a stepped surface 301 that engages with the snap-fit ​​component 502. The heat-fused connector 503 is heat-fused to the stepped surface 301. The light-emitting end of the side top light 2 passes through the channel 3a and extends to the sealing strip 5. Specifically, the sealing strip 5 is made of plastic, the snap-fit ​​component 502 is a snap-fit ​​structure, and the heat-fused connector 503 is a plastic sheet. More specifically, the connecting ring 501, snap-fit ​​component 502, and sealing strip 5 are integrally injection molded. Preferably, multiple snap-fit ​​components 502 and heat-fused connectors 503 are provided. During the design process, the diameter of the side dome light through-hole 1a machined on the headliner 1 is usually larger than that of the side dome light 2. A certain gap is reserved between the side dome light 2 and the side dome light through-hole 1a. The purpose of the sealing trim 5 is to seal and cover the gap at the assembly point of the side dome light 2 and the side dome light through-hole 1a, so as to ensure the aesthetics of the visible area inside the car. In this structural design, the sealing trim 5 is double-fixed by the snap-fit ​​part 502 and the heat-fusion connector 503, which has a high connection reliability and can effectively prevent the sealing trim 5 from loosening during vehicle use; at the same time, it can also enhance the connection stability between the side dome light mounting bracket 3 and the headliner 1 to a certain extent.

[0029] In this embodiment, the roof 1 includes a roof substrate layer 101 and a roof frame 102 connected to the roof substrate layer 101. The side dome light mounting base 3 is fixed to the roof substrate layer, and the roof frame 102 is located on the side of the roof substrate layer 101 facing the side dome light mounting base 3. The flexible connector 4 has a first connecting end and a second connecting end. The first connecting end is fixedly connected to the roof frame 102, and the second connecting end is fixedly connected to the side dome light 3. Of course, the roof 1 generally also includes a skin layer 103, etc. The roof substrate layer 101 serves as the supporting substrate for the skin layer 103 of the interior of the roof 1 and is used to cover the roof frame 102 and hide the internal structure. The roof frame 102 is the main load-bearing structure of the roof, and its structural strength is relatively better than that of the roof substrate layer 101. The roof substrate layer 101 and the roof frame 102 are generally fixed by heat fusion. Here, the roof substrate layer 101 and the roof frame 102 adopt the same structure as the existing common vehicle roofs, which is prior art and will not be described in detail here. In traditional headliner structures, the side dome light mounting bracket 3 is typically mounted on the headliner frame 102. During assembly, it's necessary to align the mounting holes on both the headliner frame 102 and the headliner substrate layer 101. However, since the headliner frame 102 and the substrate layer 101 are usually fixed later via heat fusion, the assembly precision is relatively low. Mounting the side dome light mounting bracket 3 directly on the headliner frame 101 makes it difficult to ensure the installation position accuracy of the side dome light 2 and the substrate layer 101, increasing assembly difficulty and potentially affecting the interior aesthetics. Therefore, by directly mounting the side dome light mounting bracket 3 on the substrate layer 101, the installation precision of the side dome light 2 and the substrate layer 101 is directly guaranteed, reducing the assembly difficulty of the side dome light 2 and minimizing the impact on the interior aesthetics. Furthermore, in this structural design, connecting the flexible connector 4 to the headliner frame 102 of the headliner 1 better ensures the reliability of the connection between the flexible connector 4 and the headliner 1. More specifically, the flexible connector 4 here is made of flexible webbing. The two ends of the flexible webbing correspond to the first connecting end and the second connecting end of the flexible connector 4, respectively. A mounting post with threaded holes is integrally formed on the ceiling frame 102. The first connecting end is fixed to the mounting post by screws, and the second connecting end is also fixed to the side ceiling light 2 by screws.

[0030] In this embodiment, the outer circumferential surface of the side dome light mounting base 3 is provided with a connecting plate 302 that abuts against and is fixed to the outer surface of the ceiling substrate layer 101; the mounting end of the side dome light 2 is bolted to the connecting plate 302. Here, the outer side of the ceiling substrate layer 102 is the side facing outwards. Specifically, the connecting plate 302 is heat-fused to the ceiling substrate layer 101; since the ceiling substrate layer 101 is relatively thin, it is difficult to drill threaded holes on it, so heat-fusion fixing helps to ensure the connection strength between the side dome light mounting base 3 and the ceiling substrate layer 101. At the same time, by providing the connecting plate 302, the contact area between the side dome light mounting base 3 and the ceiling substrate layer 101 is increased, which helps to further enhance the connection reliability between the side dome light mounting base 3 and the ceiling substrate layer 101. More specifically, the connecting plate 302 is provided with multiple protrusions along the circumference, and the protrusions are provided with threaded holes. The mounting end of the side dome light 2 is connected to the threaded holes on the protrusions by bolts. The side ceiling light 2 is installed with bolts, which ensures the reliability of the connection between the side ceiling light 2 and the side ceiling light mounting base 3, and at the same time, it is easy to assemble.

[0031] In this embodiment, the roof 1 further includes a skin layer 103 connected to the roof substrate layer 101 facing the interior of the vehicle; the side dome light through-hole 1a includes a first hole 103a and a second hole 101a, the first hole 103a is formed in the skin layer 103, and the second hole 101a is formed in the roof substrate layer 101, the first hole 103a and the second hole 101a are coaxial, and the circumferential edge of the first hole 103a is folded towards the second hole 101a to form a flange 103a1. The skin layer 103 is the visible part of the vehicle roof structure that is in direct contact with the occupants. Usually, the skin layer 103 is fixed to the roof substrate layer 102 with hot melt adhesive, which is existing technology and will not be described in detail here. More specifically, in this embodiment, the sealing strip 5 is set in the first hole 103a, and after the side dome light 2 is installed, it is flush with or slightly lower than the inner surface of the skin layer 103 to avoid occupying interior space. The flange 103a1 provided at the circumferential edge of the first hole 103a helps to improve the structural strength of the first hole 103a.

[0032] In this embodiment, the side dome light mounting base 3 has an annular boss 303 on the side facing the roof substrate layer 101. The annular boss 303 is engaged between the second hole 101a and the flange 103a1. It is understood that the second hole 101a is larger than the first hole 103a, and the annular boss 303 is positioned in the gap between the second hole 101a and the flange 103a1. Therefore, the installation and cooperation of the annular boss 303 with the flange 103a1 and the second hole 101a improves the installation reliability of the side dome light mounting base 3 and the roof 1, enhances the impact resistance of the side dome light mounting base 3, and thus improves the vehicle's safety.

[0033] In this embodiment, a positioning notch 101a1 is provided on the circumferential edge of the second hole 101a, and a positioning boss 303a is provided on the circumferential surface of the annular boss 303, which engages with the positioning notch 101a1. Specifically, there are two positioning notches 101a1 and two corresponding positioning bosses 303a. Thus, through the positioning notches 101a1 and positioning bosses 303a, when the side ceiling light mounting base 3 is assembled, the positioning bosses 303a engage with the positioning notches 101a1, which facilitates accurate positioning of the installation angle of the side ceiling light mounting base 3. At the same time, the positioning bosses 303a engaged with the positioning notches 101a1 can effectively restrict the rotation of the side ceiling light mounting base 3, thereby further improving the installation stability of the side ceiling light mounting base 3.

[0034] In this embodiment, multiple snap-fit ​​pieces 502 and heat-fusion connectors 503 are provided and evenly arranged circumferentially along the end face of the sealing strip 5. Specifically, there are three snap-fit ​​pieces 502 and six heat-fusion connectors 503, with two heat-fusion connectors 503 arranged between each pair of adjacent snap-fit ​​pieces 502. By providing multiple snap-fit ​​pieces 502 and heat-fusion connectors 503, the connection reliability between the sealing strip 5 and the side ceiling light mounting base 3 is better guaranteed.

[0035] In this embodiment, the flexible connector 4 is an elastic band or elastic rope. Specifically, the flexible connector 4 is an elastic webbing. Elastic bands or elastic ropes have a simple structure and low manufacturing cost. Furthermore, due to their elasticity, they can provide a certain cushioning effect, thereby better reducing the risk of the side roof light 2 flying off and better ensuring vehicle safety.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
