The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0026] In order to describe the present invention in detail, first, the roof airbag installation structure and the automobile provided by the present invention are specifically described below:

[0027] Among them, Figure 1As shown, the roof airbag installation structure includes an assembly part 4, on which an airbag module 8 is installed, and the assembly part 4 is detachably installed on the side of the automobile roof 1 close to the interior of the vehicle. The assembly part 4 is installed on the side of the inner lining of the automobile roof 1 close to the occupant in the vehicle, which is equivalent to the assembly part 4 being directly located on the top of the occupant's head. In this way, when a danger occurs, the airbag module 8 in the assembly part 4 will directly pop out to protect the occupant's head and back neck. The installation structure of the airbag module 8 installed on the assembly part 4 is similar to the existing structure of the airbag module 8 installed on the automobile roof 1, and this application will not repeat it.

[0028] The installation structure of the roof airbag also includes a connecting piece for being arranged on the roof of the car. There are two connecting pieces, which are respectively located on both sides of the car body. Both sides of the assembly part 4 are detachably connected to the two connecting pieces.

[0029] The assembly part 4 is detachably mounted on the automobile roof 1. There are many ways to disassemble it, as long as it can be quickly removed. For example, the assembly part 4 can be mounted on the automobile roof 1 using high-strength glue as a connecting part, or it can be mounted on the automobile roof 1 using screws as connecting parts. In order to ensure reliable and beautiful installation, the present application provides slide grooves 2 on both sides of the automobile roof 1 along the length direction of the vehicle body, and the connecting part is set as the slide groove 2. Correspondingly, slide bars 3 matching the slide groove 2 are respectively provided on both sides of the assembly part 4. The assembly part 4 is detachably connected to the automobile roof 1 through the slide bar 3 and the slide groove 2; the slide bar 3 can slide in the slide groove 2, but cannot slide out. The shape and size of the slide bar 3 match the slide groove 2, so as to prevent abnormal noise caused by the left and right shaking of the assembly part 4 during driving.

[0030] When installing, the slide bar 3 enters from one end of the slide slot 2, and then slides along the length direction of the slide slot 2. When removing, it can be moved in the opposite direction. For the sake of aesthetics, the assembly part 4 in this embodiment slides forward from the rear of the vehicle body, and a stopper can be set at the front of the slide slot 2, so that the slide bar 3 can be limited to prevent the front part of the slide bar 3 from sliding out of the slide slot 2.

[0031] After the assembly part 4 is installed, in order to prevent the assembly part 4 from sliding and making abnormal noise during the vehicle formation process, a fastening module is installed on the assembly part 4, and the assembly part 4 is locked on the connecting part through the fastening module. In this embodiment, the assembly part 4 is locked in the slide groove 2 so that it cannot slide forward and backward or shake left and right. The fastening module can be installed in front of or behind the assembly part 4, but in order not to affect the field of vision in front, the fastening module is generally installed at the rear of the assembly part 4, that is, the rear of the vehicle body.

[0032] The fastening module can be used to fix the assembly 4 by means of a lock, or it can be used to fix the assembly 4 by means of a bolt. Figure 2As shown, the fastening module includes a transmission assembly 5 and a telescopic fixing assembly 6, and the telescopic fixing assembly 6 is installed on both sides of the transmission assembly 5. The transmission assembly 5 is used to control the length of the telescopic fixing assembly 6, and the telescopic fixing assembly 6 enters the slide slot 2 to lock the assembly 4.

[0033] like Figure 6 As shown, a locking groove 7 is provided in the slide groove 2. The locking groove 7 can be provided in the slide groove 2 on one side or in the slide grooves 2 on both sides. The locking groove 7 is located at a point behind the slide groove 2 close to the vehicle body. The side of the fastening module close to the slide groove 2 is inserted into the locking groove 7. After one end or both ends of the telescopic fixing component 6 enter the locking groove 7, the fastening module drives the assembly part 4 to stop moving, and is locked in the front and rear directions and the left and right directions of the vehicle.

[0034] The length of the slide bar 3 is smaller than the length of the assembly part 4, so that the telescopic fixing assembly 6 can enter the slide groove only after being extended.

[0035] Among them, Figure 5 As shown, the telescopic fixing assembly 6 includes a fixed section 601 and a movable section 602. The movable section 602 is located at both ends of the fixed section 601. The fixed section 601 is movably connected to the transmission assembly 5. A movable space is provided in the assembly part 4 so that the movable section 602 can move left and right in the assembly part. The position of the fixed section 601 relative to the automobile roof 1 will not change, and the movable section 602 can move to enter the locking groove 7 or leave the locking groove 7.

[0036] The locking groove 7 is wedge-shaped, and the end of the fastening module matches the shape of the locking groove 7, that is, the shape of the side of the movable section 602 close to the locking groove 7 matches the locking groove 7, and the locking groove 7 is set in a wedge shape, which can play a guiding role when the movable section 602 begins to enter the locking groove 7. The wedge shape can be a triangle or a trapezoid, as long as the size of the locking groove 7 gradually decreases from the time the movable section 602 enters, so that the movable section 602 can smoothly enter the locking groove 7.

[0037] In detail, the transmission assembly 5 includes a worm wheel 501 and a worm 502 matched with the worm wheel 501. One end of the worm 502 away from the worm wheel 501 is located outside the assembly 4, and the rest of the worm 502 is located inside the assembly 4 or between the assembly 4 and the automobile top cover 1. In this way, the structure of the transmission assembly 5 cannot be seen from the outside, which does not affect the appearance. The worm wheel 501 is arranged on the fixed section 601, and the side of the fixed section 601 close to the movable section 602 is provided with an internal thread, and the movable section 602 is provided with an external thread matching the internal thread. In this embodiment, the length of the telescopic fixed assembly 6 is adjusted by the transmission of the worm wheel 501 and the worm 502. When the worm 502 is rotated, the fixed section 601 with the worm wheel 501 rotates, and the fixed section 601 and the movable section 602 are threadedly matched, so the movable section 602 changes its length relative to the fixed section 601.

[0038] Of course, a button can also be set on the movable section 602, and the button is located outside the assembly part 4 for easy operation. The movable section 602 is connected to the fixed section 601 through a spring. When installing, the button drives the movable section 602 to move to the other end to compress the spring. After the assembly part 4 is installed in place, the button is released, and the movable section 602 is reset under the action of the spring, so that the end of the movable section 602 enters the locking groove 7. In this solution, the spring is equivalent to the transmission component 5.

[0039] In order to better control the popping out of the airbag, a module assembly 9 is installed on the assembly 4, and the module assembly 9 includes a control module 901, a level sensor 902 and a gyroscope sensor 903. The level sensor 902 and the gyroscope sensor 903 are both electrically connected to the control module 901, and the level sensor 902 and the gyroscope sensor 903 are both used to collect the roll angle signal of the vehicle body. The control module 901 is used to control the popping out of the airbag module 8.

[0040] On the other hand, the present application also provides a roof airbag, including the above-mentioned roof airbag installation structure.

[0041] On the other hand, the present application also provides a car, comprising the above-mentioned roof airbag.

[0042] When the car is driving, the level sensor 902 and the gyroscope sensor 903 collect the body roll angle signal. If a car accident occurs and the body roll angle exceeds the safe range value, the control module 901 starts the roof airbag module 8 to work, which can protect the weak body parts such as the top of the head and the back of the neck of the occupants. After the airbag module 8 of the car roof 1 is triggered, it needs to be replaced with a new one. The transmission component 5 can be rotated to drive the telescopic fixing component 6 to move, so that the telescopic fixing component 6 is separated from the wedge-shaped locking groove 7. At the same time, the slide bar 3 slides in the slide groove 2, and the assembly part 4 can be pulled out. The new assembly part 4 and other parts thereon can be replaced, and the slide bar 3 of the new assembly part 4 is aligned with the slide groove 2, and the assembly part 4 is pushed in so that the rear side of the slide bar 3 is tightly fitted with the slide groove 2. The transmission component 5 is rotated to drive the telescopic fixing component 6 to move so that the active section 602 of the telescopic fixing component 6 enters the locking groove 7, so that the airbag module 8 can be easily replaced after the car accident, without removing the lining of the car roof 1, and the maintenance is convenient, fast and efficient.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
