Technical Field

[0001] The utility model relates to a vehicle roof structure. Background Art

[0002] Conventionally, in vehicles, a structure in which a vehicle device such as a sunshade device is arranged in a roof opening surrounded by a left roof side rail, a right roof side rail, a front roof arch, and a rear roof arch under a ceiling has been widely used.

[0003] The above-mentioned sunshade device includes a pair of left and right guide frames arranged on the inner side of the left roof side rail and the right roof side rail in the vehicle width direction and extending in the vehicle length direction, a front cross beam connecting the front ends of the left and right guide frames in the vehicle width direction, an intermediate cross beam (also called an intermediate roof arch) connecting the middle parts of the left and right guide frames in the vehicle length direction in the vehicle width direction, and a plate-shaped shading component supported by the left and right guide frames so as to be freely slidable forward and backward.

[0004] In addition, nuts are installed on the upper surface of the portion of each guide frame connected to the middle cross beam by welding, and each guide frame is fastened to the middle cross beam by passing bolts from top to bottom through the mounting portion of the middle cross beam and the portion of the guide frame connected to the middle cross beam and tightening them on the above-mentioned nuts.

[0005] However, in the above-mentioned conventional structures, the roof crossbar (also called a roof reinforcement) similar to the front crossbar, the middle crossbar and other roof frame members is not used for mounting the sunshade device. In other words, the above-mentioned conventional technology does not reveal a technical concept of effectively using the roof crossbar to mount the vehicle device. Utility Model Content

[0006] In view of the above situation, an object of the present invention is to provide a roof structure in which a roof cross member is effectively and conveniently used for mounting a vehicle device.

[0007] As a technical solution to the above-mentioned technical problems, the utility model provides a roof structure, which includes a roof of a vehicle, a pair of roof side beams extending on both sides of the roof in a vehicle width direction below the roof, a roof cross beam mounted on the pair of roof side beams in a vehicle width direction, and a roof lining covering the roof cross beam below the roof cross beam, characterized in that the roof cross beam is detachably fastened to the pair of roof side beams by fasteners, and the roof cross beam is a load-bearing component equipped with a vehicle device.

[0008] Based on the above structure of the utility model, the roof cross beam is effectively and conveniently used to carry the vehicle device. Specifically, since the roof cross beam is a load-bearing member, the roof cross beam that was previously only used to reinforce the roof structure can also be used to carry the vehicle device; and since the roof cross beam is detachably fastened to the roof side beam, the vehicle user can easily install and remove the vehicle device as needed.

[0009] In addition, in the above-mentioned roof structure of the utility model, it is preferred that the roof cross beam has a main body portion in the shape of a long plate extending horizontally along the vehicle width direction, transverse flanges formed on both sides of the width direction of the main body portion and protruding from the main body portion, longitudinal flanges formed at both ends of the length direction of the main body portion and protruding from the main body portion, and reinforcing ribs extending along the length direction and protruding from the main body portion in the middle portion in the width direction of the main body portion.

[0010] This structure enables the roof cross member to have high strength and to easily carry (install and support) various vehicle devices.

[0011] In this case, preferably, the longitudinal flange of the roof cross member is detachably fastened to the roof side rail by the fastener, and the vehicle device is detachably mounted on a main body portion or a transverse flange of the roof cross member.

[0012] Based on this structure, the roof crossbar can be firmly and detachably fixed to the roof of the vehicle, and the vehicle device can be detachably mounted on the roof crossbar. Therefore, the vehicle user can conveniently replace the mounted vehicle device or change the number and arrangement position of the mounted vehicle device as needed.

[0013] In addition, in the above-mentioned roof structure of the present invention, it is preferred that the ceiling lining is configured to be openable toward the inside of the vehicle compartment so that at least the fastener is exposed in the vehicle compartment.

[0014] Based on this structure, the roof crossbar can be easily installed and removed without removing the ceiling. Therefore, the roof crossbar can be removed to install or remove the vehicle device, and then the roof crossbar can be installed on the roof side rail. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0019] Figure 1 1 is a top view showing a schematic structure of an embodiment of the roof structure of the present invention. Figure 2 is from Figure 1 The cross-sectional view seen from the direction of the arrow on the (2)-(2) line section. Figure 3 is from Figure 1 The cross-sectional views are taken along the arrow direction of the (3)-(3) line section. In these figures, "Up" indicates the upper side of the vehicle, "Fr" indicates the front side of the vehicle, "Lh" indicates the left side of the vehicle, and "Rh" indicates the right side of the vehicle.

[0020] Figure 1 to Figure 3 In the example shown, the vehicle 1 includes a roof 2, a pair of roof side rails 3, a roof cross rail 4, a roof headlining 5, a side airbag 6, and a side trim 7. The structures of these components are described below. In the following description, the width direction of the vehicle 1 is referred to as the vehicle width direction, and the length direction of the vehicle 1 is referred to as the vehicle length direction.

[0021] The ceiling 2 is a roof panel of the vehicle 1 and is made of metal, reinforced fiber, glass, or the like.

[0022] The pair of left and right roof side rails 3 are provided below the ceiling 2 so as to extend along side edges of both sides (Rh side and Lh side) of the ceiling 2 in the vehicle width direction.

[0023] The roof crossbar 4 is also called a roof reinforcement. Figure 1 As shown, the roof cross member 4 is provided so as to span between middle regions of the pair of roof side rails 3 in the vehicle length direction in the vehicle width direction.

[0024] like Figure 2 and Figure 3As shown, the roof cross member 4 has a long plate-shaped main body 41 extending horizontally in the vehicle width direction, transverse flanges 42 formed on both sides of the main body 41 in the width direction (consistent with the vehicle length direction) and protruding from the main body 41 toward the ceiling 2, longitudinal flanges 43 formed at both ends of the main body 41 in the length direction (consistent with the vehicle width direction) and protruding from the main body 41 toward the ceiling 2, and reinforcing ribs 44 extending in the length direction of the main body 41 at the middle portion of the width direction of the main body 41 and protruding from the main body 41 toward the ceiling 2. Therefore, the roof cross member 4 is a load-bearing member with high strength.

[0025] Usually, a B-pillar 8 is disposed outside the middle region of the roof side beam 3, and the B-pillar 8 cooperates with the roof cross beam 4 as a reinforcement member to improve the strength of the roof frame structure of the vehicle 1. That is, in the prior art, the roof cross beam 4 is only a member for reinforcing the roof structure.

[0026] Both ends (left and right ends) in the longitudinal direction of the roof cross member 4 are detachably fastened to the middle regions in the vehicle length direction of the pair of roof side rails 3 by fasteners.

[0027] Figure 2 Only the fastening structure of the right end of the roof crossbar 4 is shown, and the fastening structure of the left end is the same. Figure 2 As shown, the fasteners are, for example, bolts 9 and nuts 10, and the nut 10 is fixed to the flange 31 of the roof side rail 3 extending to the bottom of the ceiling 2 by welding. The longitudinal flange 43 of the roof cross rail 4 is fastened to the flange 31 of the roof side rail 3 by inserting the bolt 9 from the lower side (inside the vehicle compartment) into a through hole (reference numeral omitted) formed on the longitudinal flange 43 of the roof cross rail 4 and tightening it on the nut 10.

[0028] In the present embodiment, three electronic components as vehicle devices, for example, a first electronic component 21, a second electronic component 22, and a third electronic component 23 are mounted on the roof crossbar 4 as a load-bearing member. These electronic components will be described below.

[0029] The first electronic component 21 is, for example, an AM / FM radio antenna. The second electronic component 22 is, for example, a television antenna. The third electronic component 23 is an ITS (Intelligent Transport Systems) antenna.

[0030] Among them, ITS is a high-end road traffic system that assists safe driving. It can use roadside infrastructure installed in vehicles or on roads to conduct wireless communications between vehicles and notify vehicle drivers of information about the presence of vehicles or people outside the driver's visual range.

[0031] The first electronic component 2 , the second electronic component 22 , and the third electronic component 23 are detachably mounted on the roof rail 4 by, for example, respective brackets and fasteners.

[0032] Here, the first electronic component 21 is taken as an example to explain the mounting structure of the electronic component. Figure 2 As shown, the first electronic component 21 has a bracket 13, and the first electronic component 21 is detachably mounted on the roof beam 4 by inserting a bolt 14 as a fastener into a through hole (not shown) formed at a predetermined position of the bracket 13 and tightening the bolt 14 into an internal threaded hole (not shown) formed on the main body 41 of the roof beam 4.

[0033] In the same manner, the second electronic component 22 and the third electronic component 23 are also detachably mounted on the roof rail 4 by respective brackets and fasteners (not shown).

[0034] In addition, if Figure 3 As shown, a LiDar (Light Detection and ranging) of an A-DAS (Advanced Driver Assistance Systems) is also provided on the upper side of the ceiling 2 (outside the cabin of the vehicle 1 ) as a fourth electronic component 24 .

[0035] ADAS is a safety driving assistance system that uses sensors such as LiDar to understand the surrounding conditions during driving and inform the driver of the surrounding conditions to implement hazard warnings and control steering and braking functions. LiDar is a sensor that uses information from reflected light by irradiating a laser to measure the distance to an object and the shape of the object.

[0036] In addition, if Figure 3 As shown, an image display device as a fifth electronic component 25 is further provided on the lower side of the ceiling lining 5 (inside the cabin of the vehicle 1). The image display device is, for example, a liquid crystal panel display. The fifth electronic component 25 is mounted on the ceiling lining 5 via a hinge (reference numeral omitted) so as to be movable in a horizontal posture and a vertical posture.

[0037] In this embodiment, the ceiling lining 5 is arranged below the roof crossbar 4 to cover the roof crossbar 4. Figure 2 As shown, mounting bases 11 are fixed to predetermined positions (here, both sides in the vehicle width direction) of the ceiling lining 5. Each mounting base 11 is detachably mounted on the transverse flange 42 of the roof cross member 4 by means of a clamp 12. Therefore, the ceiling lining 5 can be fully or partially opened toward the inside of the vehicle compartment by removing all or part of the clamps 12.

[0038] Here, the installation positions of the mounting bases 11 on the headliner 5 are set so that each pair of fasteners (bolts 9 and nuts 10) fastening the longitudinal flange 43 of the roof cross member 4 corresponds to at least one position of the base 11, that is, there is at least one mounting base 11 near each pair of fasteners (bolts 9 and nuts 10) for the roof cross member 4. In this way, when the clamp 12 fixing the mounting base 11 is removed and a part of the headliner 5 is opened, the corresponding fasteners (bolts 9 and nuts 10) for the roof cross member 4 can be exposed in the cabin of the vehicle 1.

[0039] Based on this structure, the roof crossbar 4 can be easily installed or removed without completely removing the ceiling lining 5. Therefore, when it is necessary to install or remove the electronic device (21-23), the roof crossbar 4 can be removed to install or remove the electronic device (21-23), and then the roof crossbar 4 can be installed on the roof side rail 3.

[0040] In addition, if Figure 2 As shown, the side airbag 6 is arranged on the inner side of the roof side rail 3. The side trim 7 is provided to cover the side airbag 6.

[0041] As described above, in the embodiment of the present invention, the roof cross member 4 on which the first electronic component 2, the second electronic component 22, and the third electronic component 23 as vehicle devices are mounted is detachably fastened to the roof side rail 3 of the vehicle 1 by the fasteners (bolts 9, nuts 10). That is, the roof cross member 4, which was conventionally used only to reinforce the roof structure, is also used to mount the vehicle devices.

[0042] Furthermore, the roof cross bar 4 and the vehicle device can be installed or removed simply by removing the clamp 12 for fixing the roof lining 5 from the inside of the vehicle 1 or partially removing the clamp 12 for fixing the roof lining 5 so as to fully or partially open the roof lining 5. Therefore, the user of the vehicle 1 can conveniently replace the vehicle device mounted on the roof cross bar 4, change the number of mounted vehicle devices and the arrangement position, etc. according to the needs.

[0043] However, the present invention is not limited to the description in the above-mentioned embodiment, and various applications and modifications can be implemented.

[0044] The roof rail 4 in the above-described embodiment may be disposed in any region in the vehicle length direction below the ceiling 2 .

[0045] In addition, the roof cross member 4 may also be configured such that the transverse flange 42 , the longitudinal flange 43 , and the reinforcing ribs 44 protrude from the main body 41 in a direction away from the ceiling 2 .

[0046] In addition, the vehicle device mounted on the roof rail 4 is not limited to an electronic device, and may be another type of device.
