Description

Technical Field

[0002] The automotive industry continues to advance with the times. In more temperate climates, people are increasingly drawn to convertibles. However, given the complexities of driving, safety is a top priority for automakers when designing and for consumers when choosing a model. Compared to sedans, convertibles lack the protection of a roof, making safety a major sales challenge.

[0003] The most common solution for convertible collision safety is to install a fixed anti-rollover bracket behind the rear seats. While this protects passengers, the bracket's overall height compromises the convertible's aesthetics and passenger space. To address these issues, the industry has introduced an innovative design: a liftable anti-rollover device. This device can be stowed away when not in use, with a drive mechanism raising the support beam only when needed to provide the necessary protection.

[0046] The following describes embodiments of the present invention in detail, 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 are not to be construed as limiting the present invention.

[0047] Reference below Figures 1-9 An anti-rollover device 100 according to a first embodiment of the present invention will be described.

[0048] like Figure 4-Figure 5 and Figure 8-Figure 9As shown, according to the anti-roll device 100 of the first aspect embodiment of the present invention, the anti-roll device 100 includes: a mounting bracket 10, a support beam 20, a first drive member 30 and a locking mechanism 40, and 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 drive 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 provided on the mounting bracket 10 and includes: a locking member 41 and a second drive 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 in the storage position, and in the unlocking position, the locking member 41 releases the support beam 20, and the second drive 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.

[0049] Among them, the mounting bracket 10 mainly provides installation 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 to form a support 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 driving force for the movement of the support beam 20 between the storage position and the raised 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 raised position by the first drive member 30, thereby achieving a protective effect.

[0050] 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-roll device 100 and reducing the space occupied by the anti-roll 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.

[0051] When the vehicle rolls over, the locking member 41 is driven from the locked position to the unlocked position by the second driving member 42, thereby releasing the support beam 20, and then the first driving member 30 drives the support beam 20 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 process, preventing the roof and 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 force of the vehicle rollover can be transmitted to the entire vehicle body through the anti-rollover device 100, thereby avoiding the external force of the collision from directly invading the passenger compartment, thereby reducing the risk of occupant injury and improving vehicle safety performance.

[0052] It can be understood that in order for the support beam 20 to be activated, the locking member 41 must first be driven by the second driving member 42 to unlock the support beam 20, and then the first driving 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-roll device 100 be guaranteed, but the risk of the support beam 20 being ejected due to accidental touch can also be reduced, thereby increasing the safety of the use of the anti-roll device 100.

[0053] According to the anti-roll device 100 of the embodiment of the present invention, by providing a locking mechanism 40, the normal operation of the anti-roll device 100 can be ensured while reducing the risk of the support beam 20 popping out due to accidental touch, thereby increasing the safety of the anti-roll device 100.

[0054] According to some embodiments of the present invention, Figure 4-Figure 5 As shown, the first driving member 30 is an elastic member. 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 elastically deformed. 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 raised position. The elastic member has a relatively simple structure and a fast response speed. Therefore, setting the first driving member 30 as an elastic member can reduce the design difficulty and production cost of the anti-roll device 100; at the same time, it can also shorten the time it takes for the support beam 20 to move from the storage position to the raised position, thereby improving the response speed.

[0055] 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.

[0056] According to some embodiments of the present invention, the second driving member 42 is a gas generator. Gas generators have a simple structure, fast response speed, and high safety. Therefore, using a gas generator as the second driving member 42 can reduce the production difficulty of the entire anti-rollover device 100 and improve the safety of the entire anti-rollover device 100.

[0057] According to some embodiments of the present invention, Figure 5 and Figure 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, after the anti-roll 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 enabling the anti-roll device 100 to be reused.

[0058] Optional, e.g. Figure 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 base 44. The locking mechanism 40 uses the torque of the torsion spring to drive the locking member 41 to the locked position and maintain it stationary in the locked position. The torsion spring has a simple structure and is relatively low in cost. Therefore, using a torsion spring as the first elastic member 43 can reduce the production cost of the entire anti-roll device 100.

[0059] According to some embodiments of the present invention, Figure 5 As shown, the support beam 20 is provided with a lock buckle 21 that locks with the locking member 41. 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. 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. The lock buckle 21 has a simple structure and low cost, thereby simplifying the structure of the support beam 20 and reducing the difficulty and cost of producing the support beam 20.

[0060] Optionally, the lock buckle 21 and the support beam 20 can be movably connected. In this way, 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.

[0061] According to some embodiments of the present invention, Figure 5As shown, the anti-roll device 100 further includes a first mounting base 44, to which the locking member 41 is fixed. A guide groove 441 extending in the vertical direction is formed on the first mounting base 44, and the lock buckle 21 is movably engaged in the guide groove 441. Thus, when the support beam 20 is retracted, the lock buckle 21 can move to its initial position through the guide groove 441, thereby improving the locking accuracy of the locking member 41.

[0062] 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. In this way, 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.

[0063] According to some embodiments of the present invention, Figure 4 and Figure 8 As shown, the anti-roll device 100 further includes a guide mechanism 50, which includes a first guide member 51 and a second guide member 52 that slide in the vertical 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. This ensures that the support beam 20 can move along a predetermined path or direction, thereby improving the accuracy and stability of the movement of the support beam 20.

[0064] According to some embodiments of the present invention, Figure 4 and Figure 8 As 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 is slidably engaged in the guide sleeve, and the guide sleeve acts as a limiter for the guide rod. Therefore, it can be understood that in this embodiment, the directional movement of the guide rod is limited by the guide sleeve to limit the directional movement of the support beam 20. The guide sleeve and the guide rod not only play a guiding role, but also increase the strength of the support beam 20 and the mounting bracket 10. Therefore, 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. This allows the guide mechanism 50 to ensure the directional movement of the support beam 20 while also increasing the structural strength of the entire anti-rollover device 100.

[0065] According to some embodiments of the present invention, Figure 4 and Figure 8As shown, the first driving member 30 is an elastic member that is sleeved radially outwardly of the guide rod and at least partially disposed within 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 will be appreciated that the guide mechanism 50 can also guide the driving direction of the first driving member 30, ensuring that the driving direction of the first driving member 30 always remains in the up-down direction, thereby further ensuring the directional movement of the support beam 20 and increasing the lifting speed of the support beam 20.

[0066] 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.

[0067] According to some embodiments of the present invention, Figure 4 and Figure 8 As shown, there are multiple guide mechanisms 50, which are arranged at intervals. This can further enhance the guiding function of the guide mechanism 50, further ensure the directional movement of the support beam 20, and thus further enhance the reliability of the anti-rollover device 100.

[0068] For example, the number of the guide mechanisms 50 may be two, three or more. Figure 4 As shown, there are two guide mechanisms 50 , which are arranged at intervals along the left-right direction.

[0069] According to some embodiments of the present invention, Figure 5 and Figure 9 As shown, the anti-rollover device 100 further includes a first stopper 61 and a second stopper 62. The first stopper 61 is disposed on the support beam 20, and the second stopper 62 is disposed on the mounting bracket 10. When the support beam 20 is in the raised position, the first stopper 61 is configured to cooperate with the second stopper 62 to limit the position of the support beam 20. It will be understood that the cooperation between the first stopper 61 and the second stopper 62 can prevent the support beam 20 from falling out of the mounting bracket 10, thereby ensuring the normal operation of the anti-rollover device 100.

[0070] According to some embodiments of the present invention, Figure 5 and Figure 9As 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.

[0071] According to some embodiments of the present invention, Figure 5 and Figure 9 As shown, the anti-rollover device 100 further includes a third stopper 63 and a fourth stopper 64. The third stopper 63 is disposed on the support beam 20, and the fourth stopper 64 is disposed on the mounting bracket 10. When the support beam 20 moves from the stowed position to the raised position, the third stopper 63 is configured to engage with the fourth stopper 64 to limit movement of the support beam 20 away from the raised position. It will be appreciated 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 movement, thereby improving the safety of the support beam 20 during its upward movement.

[0072] According to some embodiments of the present invention, Figure 5 and Figure 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 raised position, the ratchet tooth is adapted to engage with the rack. Specifically, the rack extends in the vertical direction and is formed with multiple racks. When the support beam 20 moves from the storage position to the raised position, the ratchet tooth is adapted to fit within the rack. When the support beam 20 moves from the storage position to the raised position, the ratchet tooth slides over the teeth of the rack. When the support beam 20 moves from the raised position to the storage position, the ratchet tooth presses 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 its upward movement.

[0073] According to some embodiments of the present invention, Figure 5 and Figure 9 As shown, in the direction from which the pawl teeth are directed toward the rack, the pawl teeth extend downward at an angle, and in the direction from which the rack teeth are directed toward the pawl teeth, the meshing teeth of the rack extend upward at an angle. In this way, when the support beam 20 moves from the stowed position to the raised position, the pawl teeth can slide over the teeth of the rack, thereby ensuring the upward state of the support beam 20. When the support beam 20 moves from the raised position to the stowed position, the pawl teeth generate a downward force, and at this time, the meshing teeth generate an upward force on the pawl teeth, thereby the pawl teeth press against the meshing teeth of the rack, and the meshing teeth of the rack support the pawl teeth, thereby supporting the support beam 20, preventing the support beam 20 from falling downward, and ensuring the safety of the support beam 20 during its upward movement.

[0074] According to some embodiments of the present invention, Figure 5 and Figure 9 As shown, the third limiting member 63 is movable between a fixed position and a released position. When the third limiting member 63 is in the fixed position, the pawl teeth are adapted to engage with the rack, while in the released position, the pawl teeth are spaced away from the rack. This allows the third limiting member 63 to cooperate with the fourth limiting member 64 to restrict the support beam 20 from moving away from the raised position while also being able to separate from the fourth limiting member 64. This allows the support beam 20 to be raised and recovered, thereby enabling the anti-rollover device 100 to be recycled, thereby reducing vehicle maintenance costs.

[0075] According to some embodiments of the present invention, Figure 4-Figure 5 and Figure 8-Figure 9 As shown, the anti-roll device 100 further includes a drive mechanism 70 connected to the third stopper 63 for driving the third stopper 63 to rotate between a fixed position and a released position. A rotary driving mechanism is generally more compact than a linear motion mechanism, thereby further improving the compactness of the anti-roll device 100 and further reducing the space occupied by the anti-roll device 100, making the anti-roll device 100 suitable for use in spaces with limited space, thereby improving the applicability of the anti-roll device 100.

[0076] 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 this application.

[0077] According to some embodiments of the present invention, Figure 4-Figure 5 and Figure 8-Figure 9 As 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 limiting member 63. The pull ring 72 is adapted to pull the third limiting member 63 from the fixed position to the released position via the pull rope 71. It will be appreciated that in this embodiment, the anti-roll device 100 manually pulls the pull rope 71 to drive the third limiting member 63 to rotate from the fixed position to the released position, thereby achieving the retraction of the support beam 20. The manual structure is relatively simple, thereby reducing the design complexity and production cost of the anti-roll device 100.

[0078] The drive mechanism 70 further includes a second elastic member 73. One end of the second elastic member 73 is fixed to the support beam 20, and the other end of the second elastic member 73 abuts the third stopper 63 to drive the third stopper 63 to rotate from the released position to the fixed position. Specifically, as the support beam 20 moves from the stowed position to the raised position, the second elastic member 73 continuously exerts a thrust on the third stopper 63, causing the pawl teeth to engage with the rack. This prevents the support beam 20 from falling downward during the upward movement, thereby improving the safety of the support beam 20 during its upward movement.

[0079] Optionally, the first stopper 61 is a second mounting seat, which is formed in a downwardly opening U-shape and has a cavity formed therein. The third stopper 63 is disposed within the cavity. The second mounting seat is fixed to the support beam 20 via bolts. When the support beam 20 is in the raised position, the upper surface of the second mounting seat abuts the lower surface of the stopper. This optimizes the layout of the anti-roll device 100, simplifies its structure, and increases the compactness of its arrangement.

[0080] Optionally, the anti-roll device 100 further includes: a second rotating shaft, the second rotating shaft being fixed to the second mounting seat, the second elastic member 73 and the third limiting member 63 being sleeved on the second rotating shaft, and the second elastic member 73 and the third limiting member 63 being both arranged inside the second mounting seat, one end of the second elastic member 73 abutting the inner surface of the second mounting seat, and the other end abutting the third limiting member 63, so as to drive the third limiting member 63 to rotate about the second rotating shaft between a fixed position and a released position. It is understood that the second rotating shaft not only serves to connect the second mounting seat and the third limiting member 63 and the second elastic member 73, but also serves to limit the position of the second elastic member 73. This not only prevents the second elastic member 73 from being offset or misaligned during operation, thereby improving the operational stability of the anti-roll device 100, but also reduces the number of parts used in the anti-roll device 100, thereby reducing the overall cost.

[0081] The vehicle according to the second embodiment of the present invention comprises the anti-rollover device 100 according to the first embodiment of the present invention and a vehicle body, wherein the anti-rollover device 100 is fixed to the vehicle body.

[0082] Specifically, the anti-roll device 100 is generally installed behind the seat. When the vehicle rolls over, the height of the anti-roll device 100 is generally higher than the height of the head of the occupant riding in the vehicle. At this time, the anti-roll device 100 can form a supporting structure with the vehicle's pillars, thereby providing a safe space for the occupant's head during the vehicle rollover, thereby reducing the risk of physical injury to the driver and passengers.

[0083] The vehicle according to the embodiment of the present invention is provided with the anti-rollover device 100 according to the first embodiment, thereby improving the overall performance of the vehicle.

The elastic member is formed as a spring, and the spring is sleeved on the guide rod. One end of the spring abuts against the mounting plate, and the other end extends into the guide sleeve and abuts against the inner wall of the upper end of the guide sleeve.

[0092] The limiting mechanism includes: a first limiting member 61, a second limiting member 62, a third limiting member 63 and a fourth limiting member 64, wherein the first limiting member 61 is arranged on the support beam 20, and the second limiting member 62 is arranged on the mounting bracket 10. When the support beam 20 is in the raised position, the first limiting member 61 is configured to be suitable for limiting and cooperating with the second limiting member 62 to limit the support beam 20; one of the third limiting member 63 and the fourth limiting member 64 is arranged on the support beam 20, and the other is arranged on the mounting bracket 10. When the support beam 20 moves from the storage position to the raised position, the third limiting member 63 is configured to be suitable for limiting and cooperating with the fourth limiting member 64 to limit the support beam 20 from moving in a direction away from the raised position.

[0093] Specifically, the first limit member 61 is the second mounting seat, the second limit member 62 is the limit block, and when the support beam 20 is in the raised position, the upper surface of the second mounting seat is suitable for abutting against the lower surface of the limit block; the third limit member 63 is formed as a ratchet tooth, and the third limit member 63 is rotatably connected to the second mounting seat through a second rotating shaft, and the third limit member 63 is rotatable between a fixed position and a released position, and the fourth limit member 64 is formed as a rack and is fixed on the mounting bracket 10. When the support beam 20 moves from the storage position to the raised position, the third limit member 63 moves to the fixed position, and the ratchet teeth are suitable for engaging with the rack; when the support beam 20 moves from the raised position to the storage position, the third limit member 63 moves to the released position, and the ratchet teeth are away from the rack.

[0094] Furthermore, in a direction from the pawl teeth to the rack, the pawl teeth extend obliquely downward, and in a direction from the rack to the pawl teeth, the meshing teeth of the rack extend obliquely upward.

[0095] The anti-roll device 100 also includes: a driving mechanism 70, wherein the driving mechanism 70 includes: a pull rope 71, a pull ring 72 and a second elastic member 73, 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 limiting member 63, and the pull ring 72 is suitable for pulling the third limiting member 63 from a fixed position to a released position through the pull rope 71, and the second elastic member 73 is a torsion spring, which is arranged on the radial outside of the second rotating shaft, and one end of the torsion spring abuts against the inner surface of the second mounting seat, and the other end abuts against the third limiting member 63 to drive the third limiting member 63 to rotate between the fixed position and the released position.

[0096] Furthermore, the second driving member 42 is a gas generator.

[0097] The support beam 20 also has a lock buckle 21 that cooperates with the locking member 41. Specifically, a mounting groove extending in the up-down direction is formed on the second mounting seat, and the lock buckle 21 can be movably fitted in the mounting groove.

[0098] When the vehicle is not rolling, the second driving member 42 is not activated, and the first elastic member 43 abuts the locking member 41, keeping the locking member 41 in the locked position. The locking member 41 locks the support beam 20, and the support beam 20 is stored and fixed in the cavity of the mounting bracket 10. When the vehicle rolls, the second driving member 42 is activated, driving the locking member 41 to the unlocked position, releasing the support beam 20. The elastic member then pushes the support beam 20 upward due to its elastic force. At this time, the pawl teeth engage with the rack. When the support beam 20 moves to the raised position, the limit plate abuts the lower surface of the limit block. When the anti-roll device 100 is not in use, the user can pull the pull rope 71 through the pull ring 72 to drive the pawl teeth to disengage the rack, and then manually press the support beam 20 downward to return it to the stored position. At this time, the locking member 41 locks the support beam 20 again.
