[0033] The following will describe some embodiments of this application in detail with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0034] In one embodiment, the present utility model provides a support device 2. Please refer to Figures 1 - 3 , the support device 2 is installed on the luggage rack of the vehicle body 1 and includes a motor 22 and a support rod 21; the motor 22 is electrically connected to a controller on the vehicle; the support rod 21 is connected to the motor 22; the support device 2 includes a support state. In the support state, when the vehicle body 1 tilts, the motor 22 drives the support rod 21 to move so that the support rod 21 supports the vehicle.

[0035] The motor 22 is set to output power to drive the support device 2 to work and prevent the vehicle body 1 from tilting; the main body of the support device 2 is the support rod 21, and the power output by the motor 22 acts on the support rod 21, driving the support rod 21 to move out and contact the ground to support the vehicle body 1; the controller on the vehicle monitors the tilting state of the vehicle body 1, and when it monitors that the vehicle body 1 is about to tilt, it outputs a signal to the motor 22. When the vehicle body 1 is about to roll over, the controller on the vehicle outputs a signal to the motor 22, and the motor 22 outputs power to move out the support rod 21 installed on the luggage rack of the vehicle body 1. The support rod 21 supports the vehicle, and the support rod 21 stably supports the vehicle body through the reaction force provided by the ground. The vehicle body, the support device 2 and the ground form a stable triangular frame to ensure that the tilting angle of the vehicle body does not exceed the rollover angle and prevent the vehicle body 1 from tilting.

[0036] The present utility model provides a support device 2. The support device 2 is installed on the luggage rack of the vehicle body 1. The support device 2 includes a motor 22 and a support rod 2, and the motor 22 is electrically connected to a controller on the vehicle. Through the above settings, when the vehicle is about to tilt, the controller on the vehicle monitors the vehicle state, and the motor 22 outputs power to drive the support rod 21 to move out and contact the ground to support the vehicle body 1, preventing the vehicle body 1 from tilting.

[0037] In one embodiment, the support device 2 includes a slide rail 23, which is fixedly connected to the vehicle body 1 and extends along a first direction D1; a support rod 21 is movably connected to the slide rail 23, and the support rod 21 moves along the first direction D1 or away from the first direction D1.

[0038] Please refer to Figure 1 , the slide rail 23 is fixedly connected to the vehicle body 1. The slide rail 23 is arranged such that the support device 2 is fixed to the vehicle body 1. The support rod 21 is movably connected to the slide rail 23, providing a movement track for the support rod 21, guiding the movement of the support rod 21 and restricting the movement range of the support device 2. Optionally, in this embodiment, the first direction D1 is the direction along the width of the vehicle. When the vehicle body is about to roll over, the support rod 21 moves along the first direction D1 or the opposite direction of the first direction D1 on the slide rail 23, so that the support rod 21 supports the ground and prevents the vehicle body from rolling over. The slide rail 23 and the vehicle body 1 can be fixedly connected by bolts, welding or clamping.

[0039] In a specific embodiment, please refer to Figure 3 , when the vehicle body 1 rolls over towards the left side of the vehicle during driving, the support rod 21 moves along the first direction D1 on the slide rail 23, and the support rod 21 supports the ground on the left side of the vehicle driving direction, preventing the vehicle body from rolling over towards the left. When the vehicle body 1 rolls over towards the right side of the vehicle driving direction, the support rod 21 moves along the opposite direction of the first direction D1 on the slide rail 23, and the support rod 21 supports the ground on the right side of the vehicle driving direction, preventing the vehicle body from rolling over towards the right.

[0040] In one embodiment, please refer to Figure 1 , the support device 2 further includes a first limiting member 24, a second limiting member 25 and a slider 26; the first limiting member 24 is fixedly connected to the slide rail 23 and is arranged at one end of the slide rail 23; the second limiting member 25 is fixedly connected to the slide rail 23 and is arranged at the other end of the slide rail 23 away from the first limiting member 24; the slider 26 is fixedly connected to the support rod 21, the slider 26 is slidably connected to the slide rail 23, and the slider 26 slides between the first limiting member 24 and the second limiting member 25 to drive the support rod 21 to move.

[0041] The first limiting member 24 and the second limiting member 25 are arranged at two opposite ends of the slide rail 23, which can limit the maximum range of movement of the support device 2 on the slide rail 23, preventing the support device 2 from moving excessively or moving to an inappropriate position; when the vehicle is about to roll over, the appropriate movement range of the support device 2 can ensure that the body tilt angle does not exceed the rollover angle, preventing the vehicle from rolling over. A slider 26 is fixedly connected to the support rod 21 and is slidably connected to the slide rail 23. The slider 26 slides along the slide rail 23, and at the same time drives the support rod 21 to move between the first limiting member 24 and the second limiting member 25 along the slide rail 23. Setting the slider 26 can ensure the smooth movement of the support rod 21, which helps to accurately control the position and movement of the support device 2, reduce the friction force with the slide rail 23, and ensure that the support rod 21 does not shake or fall off when moving on the slide rail 23, thus ensuring the stability of the support device 2.

[0042] Please refer to Figure 1 and Figure 2 When in the initial state, that is, when the vehicle is driving normally, the slider 26 is locked by the first limiting member 24 and fixed at one end of the slide rail 23. Please refer to Figure 1 and Figure 3 When in the working state, that is, when the vehicle is about to tilt, the first limiting member 24 releases the lock on the slider 26, and the slider 26 slides along the slide rail 23 in the first direction D1. When the slider 26 moves to contact the second limiting member 25, the slider 26 is locked by the second limiting member 25 and fixed at the other end of the slide rail 23. The movement of the slider 26 drives the movement of the support rod 21, and the support rod 21 supports the ground to prevent the vehicle body from rolling over.

[0043] In one embodiment, the support device 2 further includes a first clamping block. The first clamping block is connected to the vehicle body 1, so that the first limiting member 24 is fixed on the vehicle body 1. The connection between the first clamping block and the vehicle body 1 can be welding, threaded connection and tenon connection. Optionally, in this embodiment, the connection between the first clamping block and the vehicle body 1 is welding.

[0044] In one embodiment, the support device 2 further includes a second clamping block. The second clamping block is connected to the vehicle body 1, so that the second limiting member 25 is fixed on the vehicle body 1. The connection between the second clamping block and the vehicle body 1 can be welding, threaded connection and tenon connection. Optionally, in this embodiment, the connection between the second clamping block and the vehicle body 1 is welding.

[0045] In one embodiment, the support device 2 further includes a first connecting member 27, and the slider 26 and the support rod 21 are fixedly connected through the first connecting member 27.

[0046] Please refer to Figure 1, a first connecting member 27 is provided, and the slider 26 and the support rod 21 are fixedly connected through the first connecting member 27. The first connecting member 27 plays a role in transmitting the moving force. The motor 22 drives the slider 26 to move, and through the first connecting member 27, the support rod 21 is driven to move, preventing the vehicle body from rolling over. The first connecting member 27 can provide a more reliable connection, preventing the unstable connection caused by directly fixedly connecting the slider 26 and the support rod 21, and reducing the risk of loosening between the slider 26 and the support rod 21; providing a stronger and more stable connection, thereby increasing the reliability and stability of the support device 2.

[0047] In a specific embodiment, the first connecting member 27 includes a ball socket and a ball head pin. The ball head pin is inserted into the ball socket and connected to the ball socket. The slider 26 is connected to the ball head pin through its own thread, and the ball socket is connected to the support rod 21 through its own thread.

[0048] In one implementation, the support rod 21 includes a first end 211 and a second end 212 that face away from each other. The support device 2 further includes a universal wheel assembly 3. The universal wheel assembly 3 is connected to the second end 212. In the support state, the support rod 21 moves along the direction from the first end 211 to the second end 212.

[0049] Please refer to Figures 1 - 3 , when the vehicle body is about to roll over, the support rod 21 moves along the direction from the first end 211 to the second end 212. Since the universal wheel assembly 3 is connected to the second end 212, the universal wheel assembly 3 contacts the ground; the first end 211 of the support rod 21 is locked by the second limiting member 25 and fixed on the slide rail 23, preventing the support rod 21 from continuing to slide. The support rod 21 firmly supports the vehicle body 1 through the reaction force of the universal wheel assembly 3 and the ground. The vehicle body 1, the support device 2 and the ground form a stable triangular framework, ensuring that the inclination angle of the vehicle body 1 does not exceed the rollover angle and preventing the vehicle body 1 from rolling over.

[0050] The universal wheel assembly 3 is provided. When in the support state, the universal wheel assembly 3 initially has rolling friction with the ground. As the contact increases, the universal wheel assembly 3 changes from rolling friction to sliding friction with the ground, and the braking force of the universal wheel assembly 3 will also gradually increase with the increase of the support time of the support rod 21, effectively shortening the time of vehicle collision and reducing the collision injury and the duration of collision injury suffered by the occupants.

[0051] In a specific embodiment, please refer to Figure 4 and Figure 5A universal wheel assembly 3 is provided at both the first end 211 and the second end 212. When the vehicle body 1 rolls over to the left of the vehicle's travel direction, the support rod 21 moves on the slide rail 23 in the first direction D1, and the universal wheel assembly 3 provided at the second end 212 contacts the ground, preventing the vehicle body 1 from rolling over to the left of the vehicle's travel direction. When the vehicle body 1 rolls over to the right of the vehicle's travel direction, the support rod 21 moves on the slide rail 23 in a direction opposite to the first direction D1, and the universal wheel assembly 3 provided at the first end 211 contacts the ground, preventing the vehicle body 1 from rolling over to the right of the vehicle's travel direction.

[0052] In one embodiment, the universal wheel assembly 3 includes a universal wheel 31 and a fixing member 32 . The fixing member 32 connects the universal wheel 31 and the support rod 21 , and the fixing member 32 drives the universal wheel 31 to rotate relative to the support rod 21 .

[0053] Please refer to Figure 1 and Figure 3 A universal wheel 31 is provided, which can rotate freely in multiple directions relative to the support rod 21. The support device 2 can adjust its contact with the ground under different ground conditions following the vehicle body 1, ensuring that the support device 2 always remains in the optimal position. When the vehicle body 1 tilts, the support device 2 can provide stable support for the vehicle body 1. A fixing member 32 is provided to connect the universal wheel 31 and the support rod 21 to prevent the universal wheel 31 from swinging or shaking when subjected to force when directly connected to the support rod 21, thereby reducing the stability of the support device 2; the fixing member 32 can provide additional support and fixation to ensure that the universal wheel 31 remains stable during movement. The fixing member 32 can increase the structural strength of the connection part and improve the durability and reliability of the entire support device 2.

[0054] In one embodiment, the universal wheel assembly 3 includes a locking member 33 , which is fixedly connected to the fixing member 32 , and the locking member 33 locks the universal wheel 31 .

[0055] Please refer to Figure 1 , setting a locking member 33 can ensure that the universal wheel 31 remains in a fixed position when needed, can increase the stability of the support device 2, and avoid accidental movement or sliding. By setting the locking member 33, when needed, the locking member 33 can lock and fix the universal wheel 31, so that the universal wheel 31 remains fixed and no longer rolls. When the universal wheel 31 contacts the ground, the universal wheel 31 and the ground undergo rolling friction, and the locking member 33 locks the universal wheel 31, and the rolling friction between the universal wheel 31 and the ground is converted into sliding friction, and the braking force of the universal wheel 31 is adjusted to the maximum, which can effectively shorten the time when the car collides and reduce the collision damage and the duration of the collision damage to the occupants. The fixed connection between the locking member 33 and the fixing member 32 can be a threaded connection, a welded connection, a clamping connection, and an adhesive connection; optionally, in this embodiment, the fixed connection between the locking member 33 and the fixing member 32 is a welded connection.

[0056] In one embodiment, the support device 2 includes a second connecting member 28. The fixing member 32 and the support rod 21 are rotatably connected through the second connecting member 28.

[0057] Please refer to Figure 1 , the second connecting member 28 is provided, the fixing member 32 is rotatably connected to the second connecting member 28, and the support rod 21 is fixedly connected to the second connecting member 28. In this way, the fixing member 32 and the support rod 21 are rotatably connected, and the fixing member 32 can rotate relative to the support rod 21. Thus, the universal wheel 31 connected to the fixing member 32 can freely rotate relative to the support rod 21 in multiple directions. The second connecting member 28 plays a role in transmitting the power of the support rod 21 to the fixing member 32, and the universal wheel 31 supports the support rod 21 through the fixing member 32, thereby preventing the vehicle body from tipping over. The second connecting member 28 can provide a more reliable connection, prevent the unstable connection caused by the direct fixed connection between the fixing member 32 and the support rod 21, and reduce the risk of loosening between the fixing member 32 and the support rod 21; provide a stronger and more stable connection, thereby increasing the reliability and stability of the support device 2.

[0058] In a specific embodiment, the second connecting member 28 includes a ball socket and a ball head pin. The ball head pin is inserted into the ball socket and connected to the ball socket. The fixing member 32 is connected to the ball head pin through its own thread, and the ball socket is connected to the support rod 21 through its own thread.

[0059] In one embodiment, please refer to Figure 6 , the support rod 21 includes a first rod body 21A, a second rod body 21C and an elastic member 21B. The first rod body 21A encloses a channel; the second rod body 21C extends into the channel, and the second rod body 21C is slidably connected to the first rod body 21A; the elastic member 21B is disposed in the channel of the first rod body 21A and connects the second rod body 21C, and the elastic member 21B elastically deforms along the extending direction of the channel.

[0060] The first rod body 21A encloses to form a channel to accommodate the second rod body 21C and the elastic member 21B. The second rod body 21C extends into the channel and is slidably connected to the first rod body 21A and connects the elastic member 21B. When the vehicle body is about to roll over, the motor 22 drives the elastic member 21B to elastically deform and generate an elastic force, causing the first rod body 21A and the second rod body 21C to move along the first direction D1, making the support rod 21 extend towards the rollover direction to support the ground and prevent the vehicle body from rolling over. At the moment when the support rod 21 contacts the road surface, if the impact load borne by the support rod 21 is greater than its design load, the elastic member 21B provided inside the support rod 21 can slowly absorb part of the impact load borne by the support rod 21 and cause the support rod 21 to gradually retract into the electric device, preventing the support rod 21 from buckling due to excessive load and resulting in unstable support, reducing the impact on the roof and the occupants in the vehicle, and avoiding secondary collision injuries to the occupants. The elastic member 21B can be a spring, a rubber tube, an elastic support, and an elastic cushion block. Optionally, in this embodiment, the elastic member 21B is a spring.

[0061] In one embodiment, the present invention provides a vehicle, which includes a vehicle body 1 and a support device 2 as described in any one of the above embodiments. The support device 2 is provided on the roof of the vehicle body 1.

[0062] Please refer to Figure 1 , setting the support device 2 on the roof of the vehicle body 1 can make full use of the space on the roof of the vehicle body 1 and does not occupy the effective space inside the vehicle. And when the vehicle body 1 tilts, the support device 2 supports the vehicle. The support device 2 firmly supports the vehicle body through the reaction force provided by the ground. The vehicle body, the support device 2, and the ground form a stable triangular framework to ensure that the tilt angle of the vehicle body does not exceed the rollover angle and prevent the vehicle body from tilting.

[0063] In one embodiment, the number of the support devices 2 is multiple, and the multiple support devices are arranged in parallel. The support device 2 extends along the first direction D1. Among them, the support rod 21 of at least one support device 2 moves along the first direction D1, and the support rod 21 of at least another support device 2 moves in the direction opposite to the first direction D1.

[0064] Please refer to Figure 1, the support device 2 extends along the first direction D1; when the vehicle rolls to the left along the travel direction, the support rod 21 of at least one support device 2 moves along the first direction D1, and the support rod 21 supports the ground on the left side of the vehicle's travel direction. The support rod 21 firmly supports the vehicle body through the reaction force provided by the ground. The vehicle body, the support device 2 and the ground form a stable triangular frame, ensuring that the tilt angle of the vehicle body does not exceed the rollover angle, preventing the vehicle body from rolling to the left. When the vehicle rolls to the side along the travel direction, the support rod 21 of at least one support device 2 moves in a direction away from the first direction D1, and the support rod 21 supports the ground on the right side of the vehicle's travel direction. The support rod 21 firmly supports the vehicle body through the reaction force provided by the ground. The vehicle body, the support device 2 and the ground form a stable triangular frame, ensuring that the tilt angle of the vehicle body does not exceed the rollover angle, preventing the vehicle body from rolling to the right.

[0065] Multiple support devices 2 arranged in parallel can distribute the load more evenly, preventing a single support device 2 from being subjected to excessive pressure. This reduces stress on the support devices 2 and the vehicle, improving overall stability. Multiple support devices 2 can cover a larger area, providing more stable support and reducing the risk of vehicle roll. Especially after contacting uneven ground, multiple support devices 2 can better adapt to changes in terrain, reducing vehicle sway or roll caused by uneven terrain. Multiple support devices 2 are arranged at the front and rear of the vehicle to prevent unstable support caused by a single support device 2.

[0066] In one embodiment, the vehicle includes a sensor that outputs a signal to move the support device 2 .

[0067] The sensors of the vehicle include a side collision sensor arranged on the B pillar of the vehicle body and a vehicle body angle sensor arranged on the C pillar of the vehicle body. The collision sensor on the B pillar is used to determine the direction of the collision of the vehicle. The vehicle body angle sensor on the C pillar is mainly used to detect the inclination angle of the vehicle body. When the collision sensor on the B pillar receives a collision signal and the vehicle body angle sensor on the C pillar detects that the inclination angle of the vehicle body is greater than a certain angle, and the vehicle body is about to roll over, the vehicle control unit (VCU) quickly outputs an instruction to control the motor 22 to drive the elastic member 21B to extend, so that the support device 2 will quickly extend in the opposite direction of the impact, support the ground, and prevent the vehicle body from rolling over. The setting of the sensors can not only prevent the vehicle from rolling over during high-speed collisions, but also apply to the quasi-static rollover of the vehicle. By formulating a quasi-static anti-rollover strategy through the VCU, when the side collision sensor on the B pillar does not recognize the collision information, but the vehicle body angle sensor on the C pillar recognizes that the inclination angle of the vehicle body is greater than the rollover angle, the support rod 21 also extends out to contact the ground, so that the vehicle reaches a balanced state again. The two vehicle anti-rollover strategies take into account both the quasi-static and high-speed side collision conditions of the vehicle, providing comprehensive protection for the safety of vehicle use. At the same time, the sensors can distinguish the severity of side collision traffic accidents, so as to calibrate and adjust the extension rate and length of the support device 2. Usually, according to the magnitude of the collision acceleration value, side collisions are divided into 3 severity levels: light, medium, and heavy. For side collision traffic accidents of different severity levels, the extension rate and extension length of the support device 2 are determined according to the vehicle size, center of gravity position, and collision acceleration, ensuring that the support device 2 can quickly respond to different working conditions.
