Description

Technical Field

[0001] This utility model relates to the field of vehicle parts, specifically to a roof armrest assembly, a vehicle roof, and a vehicle. Background Technology

[0002] Car rooftops typically have armrests positioned opposite the seats to provide support for passengers during emergency situations such as cornering or sudden braking. Current rooftop armrest installation usually requires a mounting bracket, which is welded to the upper edge beam of the roof. The bracket has embedded nuts for securing the armrest, which is then placed into mounting holes in the roof. Bolts pass through the armrest and are inserted into the nuts to complete the installation.

[0003] On the one hand, the need for additional mounting brackets increases the required layout space, the number of parts, and the cost. On the other hand, because the mounting brackets are welded to the upper beam of the roof, the welding points between the mounting brackets and the upper beam of the roof, as well as the welding points between the side panels and the upper beam of the roof, are relatively concentrated. This makes it easy for the mounting brackets to obstruct the welding points between the side panels and the upper beam of the roof, which is not conducive to the welding and assembly of the side panels and the upper beam of the roof. Moreover, since the parts used for welding to the mounting brackets at the four corners of the roof are not exactly the same, the mounting brackets cannot be used interchangeably, requiring multiple mold openings, which further increases the installation cost of the roof armrests. Utility Model Content

[0004] This utility model aims to solve the technical problem that ceiling handrails in related technologies require the use of mounting brackets for installation, which not only requires a large layout space and has high installation costs, but also easily obstructs the welding and assembly of surrounding related structures.

[0005] In a first aspect, this utility model provides a ceiling handrail assembly, including a handrail, a buckle, and a fastener. The buckle includes a locking plate and locking claws. The locking plate has a through first connecting hole, and the locking plate has at least two locking claws around the first connecting hole. The buckle is used to engage with the locking holes of the upper side beam of the ceiling through the locking claws. The handrail portion is used to be placed in the handrail mounting hole of the ceiling to correspond to the buckle. The handrail has a second connecting hole at a position corresponding to the first connecting hole. The fastener passes through the second connecting hole and the first connecting hole in sequence.

[0006] Optionally, the ceiling handrail assembly also includes a fastener, the buckle having a through first connecting hole, the buckle having claws around the first connecting hole, the buckle being used to engage with the claws in the buckle hole, the handrail having a second connecting hole at a position corresponding to the first connecting hole, the fastener passing through the second connecting hole and the first connecting hole in sequence, and opening the claws.

[0007] Optionally, the handrail includes a fixed base and a handrail body that are rotatably connected to each other. The fixed base is at least partially placed in the handrail mounting hole and is provided with the second connecting hole. The handrail body is used to rotate relative to the fixed base.

[0008] Optionally, the fixed base is provided with a first slot, and the card plate is engaged with the first slot.

[0009] Optionally, the ceiling handrail assembly further includes a transition bracket, which is disposed between the buckle and the handrail. The transition bracket has a through third connecting hole, and the fastener passes through the second connecting hole, the third connecting hole and the first connecting hole in sequence.

[0010] Optionally, the transition bracket has a second slot at one end near the buckle, and the card plate is engaged with the second slot.

[0011] Optionally, one end of each of the claws is connected to the card plate, the other end of each of the claws is bent toward the direction close to the first connection hole and used to abut against the fastener, and the portion of each claw between its two ends is bent toward the direction away from the first connection hole.

[0012] Optionally, the canopy handrail assembly also includes a plug, the first connection hole is a threaded hole, the fastener is a bolt, the head of the bolt extends out of the second connection hole, and the plug is detachably connected to the handrail and covers the head of the bolt.

[0013] Secondly, this utility model proposes a vehicle roof, including a canopy, an upper beam of the canopy, and the aforementioned canopy handrail assembly. The canopy is provided with handrail mounting holes, and the upper beam of the canopy is provided with snap holes. The handrail portion of the canopy handrail assembly is placed in the handrail mounting holes, and the snap fastener of the canopy handrail assembly is engaged in the snap holes.

[0014] Optionally, a portion of the upper side beam of the top cover protrudes towards the interior of the vehicle to form a mounting boss, and the mounting boss has the locking hole on its surface.

[0015] Thirdly, this utility model proposes a vehicle including the aforementioned roof.

[0016] The roof handrail assembly, roof, and vehicle of this utility model have at least the following advantages compared to related technologies:

[0017] The clip plate of the ceiling handrail assembly has a first connecting hole, and the handrail has a second connecting hole corresponding to the first connecting hole. Fasteners are passed through the first and second connecting holes sequentially to achieve a detachable connection between the handrail and the clip. A locking hole is directly provided on the upper edge beam of the roof cover. During installation, the claws of the clip of the ceiling handrail assembly can be engaged in the locking hole, and the handrail is positioned within the handrail mounting hole in the ceiling. The second connecting hole on the handrail is aligned and connected to the first connecting hole on the clip plate. Fasteners are passed through the second and first connecting holes to install the ceiling handrail assembly. Because the clip has low manufacturing cost, small size, and engages with the locking hole on the upper edge beam of the roof cover without welding to the upper edge beam, it also requires minimal space. Therefore, connecting the handrail to the upper edge beam of the roof cover via the clip can reduce the manufacturing cost of the ceiling handrail assembly. This design reduces manufacturing and installation costs and avoids technical issues related to welding and assembling surrounding structures such as the side panels and roof beams. Furthermore, the roof armrest assembly features detachable connections for the armrest, buckles, and roof beams. If either the buckle or the armrest is damaged, only the corresponding part needs replacement, eliminating the need for complete replacement and reducing maintenance costs. The same buckle can be used with different armrests, reducing mold development costs. Moreover, the circumferential spacing of the claws along the first connecting holes on the clamping plate allows the fasteners to push the claws outwards after passing through the second connecting holes of the armrest and the first connecting holes of the buckle, thus improving the stability of the connection between the buckle and the roof beam. Additionally, the detachable connection between the buckle and the armrest via fasteners facilitates the addition of transition brackets between the buckle and the armrest to meet the installation needs of different vehicle roofs.

The positive Z-axis indicates the top of the vehicle, and the negative Z-axis indicates the bottom of the vehicle. It should be noted that the aforementioned Z-axis representation is only for the convenience of describing this utility model and simplifying the description, and does not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0031] like Figures 1-7As shown, a ceiling handrail assembly according to an embodiment of the present invention includes a handrail 1, a buckle 2, and a fastener 3. The buckle 2 includes a locking plate 21 and a claw 22. The locking plate 21 has a through first connecting hole 211. The locking plate 21 has at least two claws 22 around the first connecting hole 211. The buckle 2 is used to engage with the locking hole 71 of the upper side beam 7 of the top cover through the claws 22. A portion of the handrail 1 is used to be placed in the handrail mounting hole 61 of the ceiling 6 to correspond to the buckle 2. The handrail 1 has a second connecting hole 111 at a position corresponding to the first connecting hole 211. The fastener 3 passes through the second connecting hole 111 and the first connecting hole 211 in sequence.

[0032] The roof armrest assembly described in this embodiment can be installed on the roof of any vehicle. The roof 6 is located below the upper side beam 7 of the roof cover. The armrest mounting holes 61 on the roof 6 are vertically corresponding to the snap holes 71 on the upper side beam 7 of the roof cover. When part of the armrest 1 is placed in the armrest mounting hole 61 of the roof 6, it can correspond to the position of the snap fastener 2 installed at the snap hole 71.

[0033] Here, armrest 1 can be a regular headliner armrest, made of plastic to ensure comfortable grip, with a color that matches the surrounding interior to avoid structural abruptness and enhance the aesthetics of the car interior. Buckle 2 can be a standard plastic buckle.

[0034] The card plate 21 is provided with a through first connecting hole 211, and at least two claws 22 are provided on the card plate 21 along the circumference of the first connecting hole 211. For example, there are two claws 22 and they are arranged symmetrically. This can reduce the number of claws 22 and simplify the structure while achieving the clamping of the buckle 2 and the card hole 71.

[0035] The buckles 2, the holes 71 and the fasteners 3 are set one-to-one. Two buckles 2, two holes 71 and two fasteners 3 can be set respectively, that is, the handrail 1 can achieve a stable connection with the upper beam 7 of the top cover through two sets of buckles 2 and fasteners 3.

[0036] In this embodiment, the latch plate 21 of the clip 2 of the ceiling handrail assembly is provided with a first connecting hole 211, and the handrail 1 is provided with a second connecting hole 111 at a position corresponding to the first connecting hole 211. Fasteners 3 are used to pass through the first connecting hole 211 and the second connecting hole 111 in sequence to achieve a detachable connection between the handrail 1 and the clip 2 of the ceiling handrail assembly. A locking hole 71 is directly provided on the upper side beam 7 of the top cover. During installation, the claws 22 of the clip 2 of the ceiling handrail assembly can be engaged in the locking hole 71, thus securing the handrail. 1. The handrail is located in the mounting hole 61 of the ceiling 6. The second connecting hole 111 on the handrail 1 is aligned and connected with the first connecting hole 211 on the clip plate 21 of the buckle 2. Fasteners 3 are used to pass through the second connecting hole 111 and the first connecting hole 211 in sequence to install the ceiling handrail assembly. Since the buckle 2 has low manufacturing cost and small size, and is engaged with the clip hole 71 of the upper side beam 7 of the top cover, it does not need to be welded to the upper side beam 7 of the top cover, and the requirements for the arrangement space are also very low. Therefore, the handrail 1 is connected to the top cover through the buckle 2. The side beam 7 reduces the manufacturing and installation costs of the roof armrest assembly and avoids technical issues related to the welding and assembly of surrounding structures, such as the side panels of the car and the side beam 7 on the roof. Furthermore, the armrest 1, buckle 2, and roof side beam 7 of the roof armrest assembly are all detachably connected. If either the buckle 2 or the armrest 1 is damaged, only the corresponding part needs to be replaced, eliminating the need for complete replacement and reducing maintenance costs. Moreover, the same buckle 2 can be adapted to different armrests 1, reducing mold development costs. Furthermore, due to the various... The claws 22 are spaced circumferentially along the first connecting holes 211 on the clamping plate 21, so that after the fastener 3 passes through the second connecting hole 111 of the armrest 1 and the first connecting hole 211 of the buckle 2, it can push the claws 22 outward and open them, thereby improving the engagement stability of the buckle 2 and the buckle hole 71 of the top beam 7; in addition, the buckle 2 and the armrest 1 are detachably connected by the fastener 3, and the transition bracket 4 mentioned below can be easily added between the buckle 2 and the armrest 1 to meet the installation needs of different car roofs.

[0037] like Figure 2 As shown, optionally, the handrail 1 includes a fixed base 11 and a handrail body 12 that are rotatably connected to each other. The fixed base 11 is at least partially placed in the handrail mounting hole 61 and is provided with the second connecting hole 111. The handrail body 12 is used to rotate relative to the fixed base 11.

[0038] Specifically, the fixed base 11 is at least partially placed in the handrail mounting hole 61 on the ceiling 6. The fastener 3 passes through the second connecting hole 111 on the fixed base 11 and the first connecting hole 211 on the buckle 2 in sequence to achieve relative fixation between the fixed base 11 and the buckle 2. The handrail body 12 of the handrail 1 can be rotatably connected to the fixed base 11 through a pin, and the handrail body 12 can rotate relative to the fixed base 11 in the up and down direction. The handrail body 12 is usually U-shaped for easy gripping. There can be two fixed bases 11, which are located at both ends of the handrail body 12. The ceiling 6 can open a handrail mounting hole 61 at the position corresponding to each fixed base 11, and each fixed base 11 can be connected to a buckle 2. That is, both ends of the handrail body 12 are connected to the upper side beam 7 of the top cover through a fixed base 11 and a buckle 2, which can ensure the stability of the installation.

[0039] When the armrest body 12 is needed, it can be rotated downward relative to the fixed base 11 to facilitate gripping the armrest body 12; when the armrest body 12 is not needed, it can be rotated upward relative to the fixed base 11 to fit against the roof 6 and avoid occupying the vertical space inside the vehicle.

[0040] like Figure 2 As shown, optionally, the fixed base 11 is provided with a first slot 112, and the card plate 21 is connected to the first slot 112.

[0041] Specifically, the upper surface of the fixed base 11 may be provided with a snap-fit ​​flange around the second connecting hole 111. The snap-fit ​​flange and the upper surface of the fixed base 11 form a first snap groove 112. The edge of the snap plate 21 of the buckle 2 is inserted into the first snap groove 112 to realize the snap-fit ​​connection between the buckle 2 and the handrail 1.

[0042] During installation, first, the clip plate 21 of the buckle 2 is snapped into the first slot 112 of the handrail 1. Then, the handrail 1 and the buckle 2 are snapped into the clip hole 71 of the upper beam 7 of the top cover. Finally, the fastener 3 is inserted to lock the buckle 2 and the handrail 1, thereby realizing the installation of the ceiling handrail assembly.

[0043] It should be noted that before snapping the buckle 2 into the buckle hole 71 of the top beam 7, the buckle 2 and the handrail 1 should be snapped together to form a whole, ensuring that the first connecting hole 211 of the buckle 2 and the second connecting hole 111 of the handrail 1 are aligned and connected, which facilitates the subsequent installation of the fastener 3.

[0044] like Figures 5-7As shown, optionally, the ceiling handrail assembly also includes a transition bracket 4, which is disposed between the buckle 2 and the handrail 1. The transition bracket 4 is provided with a through third connecting hole 41, and the fastener 3 passes through the second connecting hole 111, the third connecting hole 41 and the first connecting hole 211 in sequence.

[0045] It should be noted that the roof has a sunroof version and a non-sunroof version. In different roof structures, the position of the upper edge beam 7 of the roof remains constant, but the vertical position of the roof 6 is different. That is, in different roof structures, the vertical distance between the part of the roof 6 used to install the armrest 1 and the corresponding part of the upper edge beam 7 of the roof is different. For example, in the non-sunroof version of the roof, the top of the roof is the metal roof cover 9, the roof 6 is located below the metal roof cover 9, the upper edge beam 7 of the roof cover is located between the metal roof cover 9 and the roof 6, and the part of the roof 6 used to install the armrest 1 is attached to the corresponding part of the upper edge beam 7 of the roof cover. At this point, the buckle 2 of the roof armrest assembly can be directly inserted into the buckle hole 71 of the upper side beam 7 of the roof, and the armrest 1 can be installed in the armrest mounting hole 61 of the roof 6. In the non-sunroof version of the roof, the sunroof 8 is embedded in the metal roof 9 at the top of the roof, which causes the roof 6 to move down. The part of the roof 6 used to install the armrest 1 has a certain vertical distance from the corresponding part on the upper side beam 7 of the roof. At this point, a transition bracket 4 needs to be added between the buckle 2 of the roof armrest assembly and the armrest 1. The height of the transition bracket 4 is consistent with the vertical distance and is used for the transition connection between the buckle 2 and the armrest 1.

[0046] Here, the transition bracket 4 can be a plastic bracket. By setting a third connecting hole 41 on the transition bracket 4 that communicates with the first connecting hole 211 and the second connecting hole 111 respectively, the fastener 3 passes through the second connecting hole 111, the third connecting hole 41 and the first connecting hole 211 in sequence to achieve relative fixation between the handrail 1, the transition bracket 4 and the buckle 2.

[0047] Optionally, the transition bracket 4 has a second slot (not shown in the figure) at one end near the buckle 2, and the card plate 21 is engaged with the second slot.

[0048] Here, the second slot can be configured similarly to the first slot 112. The card plate 21 engages with the second slot on the transition bracket 4 to achieve pre-assembly of the buckle 2 and the transition bracket 4.

[0049] During installation, first snap the buckle 2 to the transition bracket 4, then snap the buckle 2 into the buckle hole 71 on the top beam 7 of the top cover, and then align the second connecting hole 111 on the handrail 1 with the third connecting hole 41 on the transition bracket 4 and insert the fastener 3 to complete the installation of the ceiling handrail assembly.

[0050] It should be noted that before the buckle 2 is inserted into the buckle hole 71 of the top beam 7, the buckle 2 and the transition bracket 4 are connected to form a whole, so that the first connecting hole 211 of the buckle 2 and the third connecting hole 41 of the transition bracket 4 are aligned and connected, which facilitates the subsequent installation of the fastener 3.

[0051] like Figure 2 and Figure 6 As shown, optionally, one end of each of the claws 22 is connected to the card plate 21, the other end of each of the claws 22 is bent toward the direction close to the first connection hole 211 and is used to abut against the fastener 3, and the portion of each of the claws 22 between its two ends is bent toward the direction away from the first connection hole 211.

[0052] Here, the lower end of each claw 22 is connected to the locking plate 21, and the upper end of each claw 22, that is, the end away from the locking plate 21, is bent towards the direction close to the first connecting hole 211. The middle part of each claw 22 is bent towards the side away from the first connecting hole 211, so that the outline of the locking structure formed by the claws 22 has a shape that is thick in the middle and thin at both ends. The outer outline of this locking structure has a guiding function, and the locking structure can be smoothly inserted into the locking hole 71 with the thinner end, and continue to be inserted until the thickest part in the middle is reached. The fastener 3 passes through the locking hole 71 and engages with the upper end of the locking hole 71 to ensure that the locking structure will not come off downwards from the locking hole 71. Furthermore, as the fastener 3 passes through the second connecting hole 111 and the first connecting hole 211 sequentially from bottom to top, it will press the upper ends of each locking claw 22 outwards to prevent each locking claw 22 from deforming towards the first connecting hole 211 and thus disengaging from the locking hole 71. This also thickens the outline of the locking structure to increase the amount of engagement between the buckle 2 and the locking hole 71, thereby ensuring the reliability of the connection between the buckle 2 and the locking hole 71.

[0053] like Figure 3 As shown, optionally, the ceiling handrail assembly also includes a plug 5, the first connecting hole 211 is a threaded hole, the fastener 3 is a bolt, the head of the bolt extends out of the second connecting hole 111, and the plug 5 is detachably connected to the handrail 1 and covers the head of the bolt.

[0054] Here, when the fastener 3 is a bolt, the head of the bolt can be facing down and the shank facing up. The shank passes through the armrest 1 and the buckle 2 from bottom to top. The head of the bolt is outside the second connecting hole 111. By covering the head of the bolt with a plug 5, the head of the bolt can be effectively covered. This not only prevents external air impurities from contaminating and corroding the head of the bolt, but also ensures the aesthetics of the car interior.

[0055] By making the first connecting hole 211 a threaded hole, when the bolt passes through the second connecting hole 111 to be inserted into the first connecting hole 211, it can be threadedly locked with the first connecting hole 211, thereby achieving relative locking between the handrail 1 and the buckle 2; or, when the bolt passes through the second connecting hole 111 and the third connecting hole 41 in sequence to be inserted into the first connecting hole 211, it can be threadedly locked with the first connecting hole 211, thereby achieving relative locking between the handrail 1, the transition bracket 4, and the buckle 2. Here, the second connecting hole 111 can be a through hole or a threaded hole. The second connecting hole 111 is provided on the fixed base 11 of the handrail 1, and the plug 5 can be snapped onto the fixed base 11 of the handrail 1.

[0056] like Figure 1 and Figure 4 As shown, another embodiment of this utility model proposes a vehicle roof, including a roof 6, a roof upper beam 7, and the aforementioned roof armrest assembly. The roof 6 is provided with armrest mounting holes 61, and the roof upper beam 7 is provided with locking holes 71. A portion of the armrest 1 of the roof armrest assembly is placed in the armrest mounting hole 61, and the buckle 2 of the roof armrest assembly is engaged in the locking hole 71. The advantages of this vehicle roof compared to related technologies are the same as those of the aforementioned roof armrest assembly, and will not be repeated.

[0057] like Figure 3 and Figure 7 As shown, optionally, a portion of the upper side beam 7 of the top cover protrudes towards the interior of the vehicle to form a mounting boss 72, and the mounting boss 72 has the locking hole 71 on its platform 721.

[0058] Specifically, the mounting boss 72 can be a hollow rectangular boss. The platform 721 of the mounting boss 72 is set parallel to the top surface of the fixing base 11 of the handrail 1, so that the fixing base 11 can fit in contact with the platform 721, increasing the contact area between the handrail 1 and the upper beam 7 of the top cover. This allows the fastener 3 to achieve a more reliable connection between the handrail 1 and the upper beam 7 of the top cover when it passes through the second connecting hole 111 on the fixing base 11 and the locking hole 71 on the platform 721.

[0059] Another embodiment of this utility model provides a vehicle including the aforementioned roof. The advantages of this vehicle compared to related technologies are the same as those of the aforementioned roof, and will not be repeated here.

[0060] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
