[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0031] Reference below Figure 1-Figure 9 An anti-rollover device 100 according to an embodiment of a first aspect of the present invention is described.

[0032] like Figure 4-Figure 5 and Figure 8-Figure 9 As shown, according to the anti-rollover device 100 of the first aspect of the present invention, the anti-rollover device 100 includes: a mounting bracket 10, a support beam 20, a first driving member 30 and a locking mechanism 40, a cavity is formed inside the mounting bracket 10; in the up and down directions, the support beam 20 is movably arranged in the cavity between a storage position and a lifting position relative to the mounting bracket 10, and in the lifting position, part of the support beam 20 extends out of the cavity; the first driving member 30 is connected to the support beam 20, and is used to drive the support beam 20 to move from the storage position to the lifting position; the locking mechanism 40 is arranged on the mounting bracket 10 and includes: a locking member 41 and a second driving member 42, the locking member 41 is movable between a locking position and an unlocking position, in the locking position, the locking member 41 locks the support beam 20 at the storage position, and in the unlocking position, the locking member 41 releases the support beam 20, and the second driving member 42 is connected to the locking member 41, and is used to drive the locking member 41 to move from the locking position to the unlocking position.

[0033] Among them, the mounting bracket 10 mainly provides mounting space for the support beam 20, the first drive member 30 and the locking mechanism 40; the support beam 20 is mainly used to extend the mounting bracket 10 when the vehicle rolls over, so as to form a supporting structure on the vehicle's pillar, thereby providing a safe space for the occupants during the vehicle rollover, thereby reducing the risk of injury to the occupants; the first drive member 30 mainly provides a driving force for the movement of the support beam 20 between the storage position and the lifting position; the locking mechanism 40 is mainly used to lock or release the support beam 20, so that the support beam 20 is stored in the cavity when the vehicle does not roll over, and is fixed relative to the mounting bracket 10; when the vehicle rolls over, the support beam 20 can be released and then driven to the lifting position by the first drive member 30, thereby achieving a protective effect.

[0034] Specifically, when the vehicle does not roll over, the locking member 41 locks the support beam 20, and the support beam 20 is received and fixed in the cavity of the mounting bracket 10. At this time, the support beam 20 does not occupy extra layout space, thereby reducing the overall size of the entire anti-rollover device 100 and reducing the space occupied by the anti-rollover device 100 during installation, so that it can be easily arranged and installed on the vehicle, and can be hidden in the exterior trim of the vehicle without affecting the aesthetic requirements of the vehicle. In addition, the cabin space can be increased, thereby improving the comfort of the user.

[0035] When the vehicle rolls over, the locking member 41 is driven by the second driving member 42 to move from the locked position to the unlocked position, thereby releasing the support beam 20, and then the first driving member 30 drives the support beam 20 to move from the storage position to the raised position. It should be noted that the raised position of the support beam 20 generally exceeds the height of the seat. In this way, when the vehicle rolls over, the support beam 20 can form a supporting structure with the vehicle's pillars, thereby providing a safe space for the occupants during the vehicle rollover, preventing the roof and the body from being deformed and squeezed toward the passengers, causing human bodies to be squeezed and injured. At the same time, the support beam 20 can also play a role in transmitting force, so that the external collision force of the vehicle rollover can be transmitted to the entire vehicle body through the anti-rollover device 100, thereby avoiding the direct invasion of the external collision force into the passenger compartment, thereby reducing the risk of occupant injury and improving the safety performance of the vehicle.

[0036] It can be understood that, in order for the support beam 20 to be activated, the second drive member 42 must first be used to drive the locking member 41 to unlock the support beam 20, and then the first drive member 30 can be used to drive the support beam 20 to extend out of the mounting bracket 10. In this way, not only can the normal operation of the anti-rollover device 100 be guaranteed, but also the risk of the support beam 20 being ejected due to accidental touch can be reduced, thereby increasing the safety of the use of the anti-rollover device 100.

[0037] According to the anti-rollover device 100 of the embodiment of the present invention, by providing a locking mechanism 40, the risk of the support beam 20 popping out due to accidental touch can be reduced while ensuring the normal operation of the anti-rollover device 100, thereby increasing the safety of the anti-rollover device 100.

[0038] According to some embodiments of the present invention, Figure 4-Figure 5 As shown, the first driving member 30 is an elastic member, and in the storage position, the elastic member is configured to undergo elastic deformation. It should be noted that the elastic member can generate elastic force when it undergoes elastic deformation. Therefore, it can be understood that in this embodiment, the elastic force of the elastic member is used to drive the support beam 20 from the storage position to the lifting position, wherein the structure of the elastic member is relatively simple and the response speed is relatively fast. Therefore, setting the first driving member 30 as an elastic member can reduce the design difficulty and manufacturing cost of the anti-rollover device 100; at the same time, it can also shorten the time for the support beam 20 to move from the storage position to the lifting position and improve the response speed.

[0039] Among them, “in the storage position, the elastic member is configured to undergo elastic deformation” is intended to explain that, in the storage position, the elastic member can be in a compressed state or in a stretched state, and the specific selection can be made according to the actual design situation.

[0040] According to some embodiments of the present invention, the second driving member 42 is a gas generator, which has a simple structure, fast response speed and high safety. Therefore, the second driving member 42 is a gas generator, which can reduce the production difficulty of the entire anti-rollover device 100 and improve the safety of the entire anti-rollover device 100.

[0041] According to some embodiments of the present invention, Figure 5 and Fig. 9 As shown, the locking mechanism 40 further includes: a first elastic member 43, one end of which is connected to the locking member 41, and is used to drive the locking member 41 to rotate from the unlocked position to the locked position. Specifically, when the anti-rollover device 100 is used, the support beam 20 is pressed back to the storage position. At this time, the first elastic member 43 drives the locking member 41 to rotate from the unlocked position to the locked position, thereby re-locking the support beam 20 for the next use, thereby realizing the repeated use of the anti-rollover device 100.

[0042] Optional, e.g. Fig. 9 As shown, the first elastic member 43 is a torsion spring, one end of which is connected to the locking member 41, and the other end is connected to the first mounting seat 44. The locking mechanism 40 drives the locking member 41 to the locking position by the torque of the torsion spring, and keeps it stationary in the locking position. The torsion spring has a simple structure and low cost. Therefore, the first elastic member 43 is a torsion spring, which can reduce the production cost of the entire anti-rollover device 100.

[0043] According to some embodiments of the present invention, Figure 5 As shown, a lock buckle 21 that locks with a locking member 41 is provided on the support beam 20. Specifically, when the locking member 41 is in the locked position, the locking member 41 locks the support beam 20 by locking the lock buckle 21, and when the locking member 41 is in the unlocked position, the locking member 41 releases the support beam 20 by unlocking the lock buckle 21, wherein the lock buckle 21 has a simple structure and low cost, thereby simplifying the structure of the support beam 20, and further reducing the production difficulty and production cost of the support beam 20.

[0044] Optionally, the lock buckle 21 and the support beam 20 can be movably connected, so that the lock buckle 21 can be prevented from being directly subjected to force when the support beam 20 is pressed back, thereby reducing stress concentration on the lock buckle 21 and reducing the probability of damage to the lock buckle 21.

[0045] According to some embodiments of the present invention, Figure 5 As shown, the anti-rollover device 100 further includes: a first mounting seat 44, a locking member 41 is fixed on the first mounting seat 44, and a guide groove 441 extending in the up-down direction is formed on the first mounting seat 44, and the lock buckle 21 can be movably fitted in the guide groove 441. In this way, when the support beam 20 is retracted, the lock buckle 21 can move to the initial position through the guide groove 441, thereby improving the locking accuracy of the locking member 41.

[0046] Optional, see Figure 5 In the direction from bottom to top, the cross-sectional area of ​​the guide groove 441 gradually increases. It can be understood that the guide groove 441 is formed in a trumpet shape, so that when the support beam 20 is pressed back, the lock buckle 21 can be more effectively guided into the guide groove 441, thereby achieving the accuracy of locking of the locking member 41.

[0047] According to some embodiments of the present invention, Figure 4 and Figure 8 As shown, the anti-rollover device 100 further includes a guide mechanism 50, which includes a first guide member 51 and a second guide member 52 that are slidably matched in the up-down direction, the first guide member 51 is arranged on the mounting bracket 10, and the second guide member 52 is arranged on the support beam 20. In this way, it can be ensured that the support beam 20 can move in a predetermined path or direction, thereby improving the accuracy and stability of the movement of the support beam 20.

[0048] According to some embodiments of the present invention, Figure 4 and Figure 8As shown, one of the first guide member 51 and the second guide member 52 is formed as a guide sleeve, and the other is formed as a guide rod, and the guide sleeve is sleeved on the outside of the guide rod. Specifically, one end of the guide rod can be slidably fitted in the guide sleeve, and the guide sleeve plays a limiting role on the guide rod. Therefore, it can be understood that this embodiment limits the directional movement of the guide rod by the guide sleeve to limit the directional movement of the support beam 20, wherein the guide sleeve and the guide rod can not only play a guiding role, but also increase the strength of the support beam 20 and the mounting bracket 10, so that one of the first guide member 51 and the second guide member 52 is formed as a guide sleeve, and the other is formed as a guide rod, so that the guide mechanism 50 can ensure the directional movement of the support beam 20 while also increasing the structural strength of the entire anti-rollover device 100.

[0049] According to some embodiments of the present invention, Figure 4 and Figure 8 As shown, the first driving member 30 is an elastic member, which is sleeved on the radial outer side of the guide rod and at least partially arranged in the guide sleeve, one end of the elastic member is fixedly connected to the guide rod, and the other end is fixedly connected to the guide sleeve. It can be understood that the guide mechanism 50 can also guide the driving direction of the first driving member 30, so that the driving direction of the first driving member 30 always maintains the up-down direction, thereby further ensuring the directional movement of the support beam 20 and improving the spring-up speed of the support beam 20.

[0050] For example Figure 4 and Figure 8 As shown, the elastic member is a spring, one end of the guide rod is connected to the bottom plate of the mounting bracket 10, and the other end is passed through the guide sleeve and is movable relative to the guide sleeve. Specifically, an accommodating cavity is formed inside the support beam 20, and the guide sleeve is arranged in the accommodating cavity. A through hole is formed at the upper end of the guide sleeve. When the support beam 20 is in the storage position, the other end of the guide rod passes through the guide sleeve through the through hole, and the spring is sleeved on the radial outside of the guide rod, and one end of the spring abuts against the bottom plate of the mounting bracket 10, and the other end extends into the guide sleeve and abuts against the inner surface of the upper end of the guide sleeve.

[0051] According to some embodiments of the present invention, Figure 4 and Figure 8 As shown, there are multiple guide mechanisms 50, and the multiple guide mechanisms 50 are arranged at intervals. In this way, the guiding function of the guide mechanism 50 can be further improved, and the directional movement of the support beam 20 can be further ensured, so that the reliability of the anti-rollover device 100 can be further improved.

[0052] For example, the number of the guide mechanisms 50 may be two, three or more. Figure 4 As shown, the number of the guide mechanisms 50 is two, and the two guide mechanisms 50 are arranged at intervals along the left-right direction.

[0053] According to some embodiments of the present invention, Figure 5 and Fig. 9 As shown, the anti-rollover device 100 further includes: a first stopper 61 and a second stopper 62, wherein the first stopper 61 is arranged on the support beam 20, and the second stopper 62 is arranged on the mounting bracket 10, and when the support beam 20 is in the raised position, the first stopper 61 is configured to be suitable for cooperating with the second stopper 62 to limit the support beam 20. It can be understood that the cooperation between the first stopper 61 and the second stopper 62 can prevent the support beam 20 from coming out of the mounting bracket 10, thereby ensuring the normal operation of the anti-rollover device 100.

[0054] According to some embodiments of the present invention, Figure 5 and Fig. 9 As shown, the first limiting member 61 is a limiting plate, and the second limiting member 62 is a limiting block. When the support beam 20 is in the raised position, the limiting plate is adapted to abut against the lower surface of the limiting block. The limiting plate and the limiting block have simple structures, thereby reducing the difficulty and cost of manufacturing the anti-rollover device 100.

[0055] According to some embodiments of the present invention, Figure 5 and Fig. 9 As shown, the anti-rollover device 100 further includes: a third stopper 63 and a fourth stopper 64, wherein the third stopper 63 is arranged on the support beam 20, and the fourth stopper 64 is arranged on the mounting bracket 10, and when the support beam 20 moves from the storage position to the lifting position, the third stopper 63 is configured to be suitable for limiting and cooperating with the fourth stopper 64 to limit the movement of the support beam 20 in a direction away from the lifting position. It can be understood that the cooperation between the third stopper 63 and the fourth stopper 64 can prevent the support beam 20 from falling downward during the upward lifting process, thereby improving the safety of the support beam 20 during the upward movement process.

[0056] According to some embodiments of the present invention, Figure 5 and Fig. 9 As shown, one of the third limiting member 63 and the fourth limiting member 64 is formed as a ratchet tooth, and the other is formed as a rack. When the support beam 20 moves from the storage position to the lifting position, the ratchet tooth is suitable for engaging with the rack. Specifically, the rack extends in the up-down direction, and a plurality of racks are formed on the rack. When the support beam 20 moves from the storage position to the lifting position, the ratchet tooth is suitable for fitting in the rack. When the support beam 20 moves from the storage position to the lifting position, the ratchet tooth will slide over the teeth of the rack, and when the support beam 20 moves from the lifting position to the storage position, the ratchet tooth will press against the teeth of the rack, thereby supporting the support beam 20, preventing the support beam 20 from falling downward, and ensuring the safety of the support beam 20 during the upward movement.

[0057] According to some embodiments of the present invention, Figure 5 and Fig. 9 As shown, in the direction from the ratchet teeth to the rack, the ratchet teeth extend downwardly at an angle, and in the direction from the rack to the ratchet teeth, the meshing teeth of the rack extend upwardly at an angle. In this way, when the support beam 20 moves from the storage position to the lifting position, it is convenient for the ratchet teeth to slide over the teeth of the rack, thereby ensuring the rising state of the support beam 20; when the support beam 20 moves from the lifting position to the storage position, the ratchet teeth will generate a downward force, at this time, the meshing teeth will generate an upward force on the ratchet teeth, thereby, the ratchet teeth will support the meshing teeth of the rack, and the meshing teeth of the rack can support the ratchet teeth, thereby supporting the support beam 20, preventing the support beam 20 from falling downward, and ensuring the safety of the support beam 20 in the upward movement process.

[0058] According to some embodiments of the present invention, Figure 5 and Fig. 9 As shown, the third limiter 63 is movable between a fixed position and a release position, wherein when the third limiter 63 is in the fixed position, the ratchet teeth are adapted to mesh with the rack, and when in the release position, the ratchet teeth are away from the rack. In this way, the third limiter 63 can cooperate with the fourth limiter 64 to limit the support beam 20 from moving in a direction away from the lifting position, and can also be separated from the fourth limiter 64, so that the support beam 20 can be lifted and recovered, and the anti-rollover device 100 can be recycled, thereby reducing the maintenance cost of the vehicle.

[0059] According to some embodiments of the present invention, Figure 4-Figure 5 and Figure 8-Figure 9 As shown, the anti-rollover device 100 further includes: a driving mechanism 70, which is connected to the third limiter 63 and is used to drive the third limiter 63 to rotate between the fixed position and the release position. The rotary push mechanism is usually more compact than the linear motion mechanism, thereby further improving the compactness of the anti-rollover device 100 and further reducing the space occupied by the anti-rollover device 100, so that the anti-rollover device 100 can be applied to occasions with limited space, thereby improving the applicability of the anti-rollover device 100.

[0060] It should be noted that the driving mechanism 70 can be an automatic driving component, a manual driving component, or a mechanical driving component, which is not limited in the present application.

[0061] According to some embodiments of the present invention, Figure 4-Figure 5 and Figure 8-Figure 9As shown, the driving mechanism 70 includes: a pull rope 71 and a pull ring 72, one end of the pull rope 71 is fixed to the pull ring 72, and the other end of the pull rope 71 is connected to the third stopper 63, and the pull ring 72 is suitable for pulling the third stopper 63 from the fixed position to the release position through the pull rope 71. It can be understood that in this embodiment, the anti-rollover device 100 drives the third stopper 63 to rotate from the fixed position to the release position by manually pulling the pull rope 71, thereby realizing the recovery of the support beam 20, wherein the manual structure is relatively simple, thereby reducing the complexity of the design of the anti-rollover device 100 and the production cost.

[0062] The driving mechanism 70 further includes: a second elastic member 73, one end of which is fixed to the support beam 20, and the other end of which is in contact with the third stopper 63, so as to drive the third stopper 63 to rotate from the release position to the fixed position. Specifically, in the process of the support beam 20 moving from the storage position to the lifting position, the second elastic member 73 always generates a thrust on the third stopper 63, so that the ratchet teeth are suitable for cooperating with the rack, thereby preventing the support beam 20 from falling downwards during the upward lifting process, thereby improving the safety of the support beam 20 during the upward movement process.

[0063] Optionally, the first stopper 61 is a second mounting seat, the second mounting seat is formed in a U-shape with an opening facing downward, a cavity is formed inside the second mounting seat, the third stopper 63 is arranged in the cavity, the second mounting seat is fixed to the support beam 20 by bolts, and when the support beam 20 is in the raised position, the upper surface of the second mounting seat abuts against the lower surface of the stopper. In this way, the layout of the anti-rollover device 100 can be optimized, the structure of the anti-rollover device 100 can be simplified, and the layout tightness of the anti-rollover device 100 can be increased.
