Abstract

A vehicle body stabilizing device capable of preventing sway of a vehicle. When the device is in use, four screw rods (13) are removed, then four support mechanisms are controlled such that an upper rail (3), a lower rail (2) and a seat are jacked up until a gap is formed between the lower rail (2) and a vehicle chassis (11), specifically, until the gap is 5 cm between the lower rail (2) and the vehicle chassis (11), and a movement gap between the top of the head of an occupant in the vehicle and the top of a cabin is at least 15 cm. In addition, the two ends of the upper rail (3) and the lower rail (2) respectively form at least 25 cm buffer gaps with the front and rear ends of the interior of the cabin, so as to prevent the ends of the upper rail (3) from abutting against the cabin structure when the upper rail (3) slides relative to the lower rail (2). Then, even if the occupant sitting on the seat makes a large movement, such as playing, in the vehicle, since the upper rail (3) and the lower rail (2) do not come into contact with the vehicle body, the seat and the upper rail (3) only slide relative to the lower rail (2), and the vehicle body is not caused to shake, and therefore the stability of the vehicle body structure is effectively ensured.

Detailed ways

The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in Figures 1 and 4, a vehicle body stabilization device for preventing vehicle shaking includes an upper rail 3, a lower rail 2 and a support mechanism. The upper rails 3 are provided on the left and right sides of the whole formed by all the seats in the carriage, that is, the upper rails 3 are provided on the left and right sides of the carriage, and the seats in the carriage are connected between the two upper rails 3. A plurality of beams 15 are fixedly connected between the two upper rails 3 , and the seat is fixedly connected to the beams 15 . Further, if the seat has a track for adjusting the front and rear movement, the track is fixed to the rail between the two upper rails 3 . on the beam.

The upper rail 3 is connected to the lower rail 2. The connection method can be referred to as shown in FIG. 5. An accommodation groove 21 is formed inside the lower rail 2. The accommodation groove 21 is arranged along the arc length direction of the lower rail. A plurality of rollers 4 are placed, the rollers 4 can be bearings, and after all the rollers are placed in the accommodating groove 21, the lower rail 2 can be welded with sealing blocks 23 at both ends to seal the lower position of the accommodating groove 21, Prevent roller 4 from falling out. The cross-section of the upper rail 3 is an I-shaped structure, the lower rail 2 is provided with ribs 22 on both sides of the opening above the accommodating groove 21, and the lower end of the upper rail is embedded in the accommodating groove 21 and located at the In the gap formed by each of the rollers 4 and the ribs 22, in this structure, the roller 4 can realize the sliding of the upper rail 3 relative to the lower rail 2, specifically swinging along the arc of the lower rail 2, and in this structure The rollers 4 can also reduce the frictional force of the upper rail 3 sliding relative to the lower rail 2, so as to reduce the vibration caused by the sliding of the upper rail 3 relative to the lower rail, so that the occupant on the seat can perform large movements, for example, there are children in the rear seat. When playing, the seat can be swung along the arc formed by the lower rail 2, so as to offset part of the vibration, thereby reducing the body shake caused by large movements.

1 and 2, the skeleton of the vehicle is provided with threaded holes 12. Specifically, as shown in FIG. 1, the threaded holes 12 are provided below the A-pillar on both sides of the vehicle and below the position of the C-pillar. And the screw holes 12 are all screwed with a screw rod 13 . Two ends of the upper rail 3 and both ends of the lower rail 2 are respectively provided with a fixing hole 32 and a fixing hole 24 , wherein the fixing hole 24 of the lower rail 2 can be arranged on the sealing block 23 . After the screw rod 13 passes through the fixing hole 32 of the upper rail 3 and the fixing hole 24 of the lower rail 2 , the screw rod 13 is screwed to the screw hole 12 for fastening. The upper rail 3 and the lower rail 2 can be both fixed in the carriage by means of the screw 13 being fixed, and the seat can be fixed at the same time.

1, 3 and 5, the support mechanism is a hydraulic cylinder 5, which is vertically fixed on the bottom of the lower rail 2, and the lower rails 2 on both sides of the carriage Both ends of the hydraulic cylinder 5 are fixed. The vehicle chassis 11 is provided with a connecting hole 14 corresponding to the position of the hydraulic cylinder 5 , and the piston rod 51 of the hydraulic cylinder 5 passes through the connecting hole 14 . The hydraulic cylinders 5 can all be controlled by a controller, which can be a vehicle control system. During operation, take out the screw 13, so that the upper rail 3 can slide relative to the lower rail 2, and the lower rail 2 loses the connection with the vehicle frame; The piston rods 51 of each of the hydraulic cylinders 5 protrude downward, so that the upper rail 3, the lower rail 2 and the seat are all jacked up, and there is a gap between the lower rail 2 and the vehicle chassis 11 when the upper rail 2 is jacked up, and the gap is preferably 5cm, and at the same time, it is necessary to leave a gap between the head of the occupants and the top of the car, and the gap is preferably 15cm. In this way, direct contact between the lower rail 2 and the carriage can be avoided, so as to prevent the occupant on the seat from transmitting vibration to the vehicle body through the lower rail 2 when performing large movements, thereby completely avoiding the shaking of the vehicle. In addition, after the lower rail 2 rises, it is also necessary to make the distance between the two ends of the upper rail 3 and the lower rail 2 and the front and rear ends of the carriage to form a buffer gap of at least 25cm to prevent the upper rail 3 from sliding relative to the lower rail 2. The end of the upper rail 3 is pushed up to the carriage structure. Further, the upper rail 3 can be slightly longer than the lower rail 2, and both ends of the upper rail 3 are fixed with baffles 31, the baffles 31 extend from the end of the lower rail 2, when the upper rail 3 slides, the baffles 31 are fixed. The plate 31 blocks the end of the lower rail 2 to prevent the lower rail 2 from sliding out of the upper rail 3 .

3 and 5, the end of the piston rod 51 is fixed with a support plate 52, the outer diameter of the support plate 52 is larger than the diameter of the connecting hole 14, and the upper surface of the support plate 52 is provided with a sealing ring 53. When the piston rod 51 is extended, the support plate 52 contacts the ground to increase the contact area between the end of the piston rod 51 and the ground, so as to ensure the stability of the upper rail 3, the lower rail 2 and the seat and prevent them from falling. In addition, when the piston rod 51 is retracted, the sealing ring 53 on the support plate 52 is pressed against the bottom of the vehicle, so that the connecting hole 14 is sealed, so as to avoid the occurrence of water seepage and the like.

To sum up, after the vehicle using the utility model is parked, the four screws 13 can be unloaded, and then the lower rail 2 can be supported upward by the support mechanism to form a gap with the interior of the carriage. Even if the occupant sitting on the seat makes a big action in the car, such as playing around, it only makes the seat and the upper rail 3 slide relative to the lower rail 2, which will not cause the body to shake. Therefore, the stability of the body structure is effectively guaranteed. To a certain extent, the occurrence of vehicle failure can be avoided.

The above are only specific embodiments of the present utility model, but the design concept of the present utility model is not limited to this, and any non-substantial changes to the present utility model by using this concept should be regarded as acts that infringe the protection scope of the present utility model.
