[0034] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0036] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the anti-submergence device provided by the embodiment of the present disclosure includes a mounting base and a support plate 4, wherein the support plate 4 includes a blocking portion 17 and a force-bearing portion 18 extending along a first direction X, and a middle area connecting the blocking portion 17 and the force-bearing portion 18, wherein the middle area is hinged to the mounting base, wherein the force-bearing portion 18 is connected to the front of the vehicle seat 19, and the blocking portion 17 can be arranged in front of the force-bearing portion 18. In this way, when a user sits on the seat, the force-bearing portion 18 is closer to the vehicle seat back 20 than the blocking portion 17. When the vehicle has a head-on collision or sudden brake, the occupant moves forward due to inertia, and the buttocks can exert a downward force on the force-bearing portion 18. The middle area is hinged to the mounting base, and then the blocking portion 17 can be lifted upward to prevent the user from continuing to slide forward, thereby avoiding or reducing the great damage caused by the waist belt portion of the safety belt to the pelvis, abdomen and even chest of the occupant, and protecting the life and health of the occupant.

[0037] The first direction X is the front-rear direction of the vehicle.

[0038] In some specific embodiments, the mounting base includes a first side plate 21 and a second side plate 22, and the first side plate 21 and the second side plate 22 are arranged oppositely; the support plate 4 is arranged between the first side plate 21 and the second side plate 22, and the middle area is close to the two sides of the first side plate 21 and the second side plate 22, respectively, and the first connecting plate 41 and the second connecting plate 42 are respectively extended along the second direction Z, and the first connecting plate 41 and the second connecting plate 42 are arranged oppositely, and the first connecting plate 41 is hinged to the first side plate 21, and the second connecting plate 42 is hinged to the second side plate 22, which can improve the strength and stability of the anti-submarine device. When the vehicle has a head-on collision or sudden braking, the occupant moves forward due to inertia, and the buttocks can apply a downward force to the force-bearing part 18. Since the first connecting plate 41 is hinged to the first side plate 21, and the second connecting plate 42 is hinged to the second side plate 22, the blocking part 17 can be lifted upward to prevent the user from continuing to slide forward, avoiding or reducing the belt part of the safety belt from causing great damage to the pelvis, abdomen and even chest of the occupant, and protecting the life and health of the occupant. The second direction Z is the up-down direction, that is, the height direction Z of the vehicle.

[0039] In some specific embodiments, along the length direction of the support plate 4, the length of the blocking portion 17 is greater than the length of the middle area, and the lengths of the blocking portion 17 on both sides of the middle area are equal. Therefore, after the blocking portion 17 is lifted upward, it can completely prevent the user from continuing to slide forward, thereby avoiding or reducing the waist belt part of the safety belt from causing great damage to the pelvis, abdomen and even chest of the occupant, thereby protecting the life and health of the occupant.

[0040] In some specific embodiments, the limiting tube 7 is connected below the force-bearing portion 18, and the limiting tube 7 extends out of the left and right sides of the force-bearing portion 18; the first side plate 21 and the second side plate 22 are respectively provided with a limiting area 212 and a limiting portion 211, and the parts of the limiting tube 7 extending out of the force-bearing portion 18 are respectively inserted into the limiting area 212, and the limiting portion 211 is provided above the limiting tube 7, and both ends of the limiting tube 7 can move in the limiting area 212 and abut against the limiting portion 211. The limiting portion 211 makes the limiting area 212 form the activity area of ​​the limiting tube 7. When the vehicle is driving normally, the limiting tube 7 abuts against the limiting portion 211, so that the support plate 4 is in a position as shown in FIG. Figure 3 The normal comfortable position shown. When the vehicle collides head-on or brakes suddenly, the occupant moves forward due to inertia, and the hips can exert a downward force on the force-bearing portion 18. Since the first connecting plate 41 is hinged to the first side plate 21, and the second connecting plate 42 is hinged to the second side plate 22, the blocking portion 17 can be lifted upward to prevent the user from sliding forward, thereby avoiding or reducing the damage caused by the waist belt part of the safety belt to the pelvis, abdomen and even chest of the occupant, and protecting the life and health of the occupant.

[0041] In some specific embodiments, the first elastic member 12 and the second elastic member 14 are further included. One end of the first elastic member 12 is connected to the first side plate 21, and the other end is connected to the blocking portion 17. One end of the second elastic member 14 is connected to the second side plate 22, and the other end is connected to the blocking portion 17. When the vehicle is running normally, the limiting tube 7 abuts against the limiting portion 211, so that the support plate 4 is in a position as shown in FIG. Figure 3 When the vehicle is in a frontal collision or sudden braking, the occupant moves forward due to inertia, and the buttocks can exert a downward force on the force-bearing part 18, so that the blocking part 17 can be lifted upward, so that the support plate 4 is in a position as shown. Figure 4 Under the action of the first elastic member 12 and the second elastic member 14, the blocking portion 17 moves toward the direction close to the floor, and the force-bearing portion 18 is lifted upward, that is, Figure 4 The blocking portion 17 rotates counterclockwise to restore the support plate 4 to the Figure 3 When in the middle state, the limiting member 14 abuts against the limiting portion 211 to prevent the blocking portion 17 from rotating too much under the pulling force of the elastic member.

[0042] By providing the first elastic member 12 and the second elastic member 14, the stability of the flipping of the support plate 4 can be improved. The first elastic member 12 and the second elastic member 14 can be springs or other elastic structures. The elastic member can make the support plate 4 in a state such as Figure 3 Normal comfort position shown.

[0043] In some specific embodiments, a first locking mechanism and a second locking mechanism are further included. The first locking mechanism is arranged on the first side plate 21, and the second locking mechanism is arranged on the second side plate 22. The first locking mechanism and the second locking mechanism are respectively locked with the limiting tube 7. When the vehicle is running normally, Figure 3 As shown, the support plate 4 is in a normal position with good comfort. Figure 4 As shown, the human body's buttocks press down the force-bearing portion 18 of the support plate 4 under the action of inertia, and the force-bearing portion 18 rotates around the hinge axis toward the floor, that is, Figure 3 The force-bearing portion 18 of the middle support plate 4 rotates clockwise until the force-bearing portion 18 is locked by the first locking mechanism and the second locking mechanism and becomes Figure 4 When the force-bearing portion 18 moves downward, the blocking portion 17 is lifted and the support plate 4 is tilted, which can reduce the possibility of the human body's hips moving forward, prevent the occupant's body from moving downward, and allow the safety belt to restrain the pelvic area of ​​the occupant, thereby protecting the safety of the occupant.

[0044] In some specific embodiments, the first locking mechanism and the second locking mechanism both include a mounting plate 32, a ratchet 31, a pawl 33 and a return spring 34; the ratchet 31 is rotatably connected to the mounting plate 32 via a ratchet shaft 35, a ratchet spring is mounted on the ratchet shaft 35, one end of the ratchet spring is connected to the ratchet 31, and the other end of the ratchet spring is connected to the mounting plate 32; the pawl 33 is rotatably connected to the mounting plate 32 via a pawl shaft 36, a pawl spring is mounted on the pawl shaft 36, one end of the pawl spring is connected to the pawl 33, and the other end of the pawl spring is connected to the mounting plate 32; the two ends of the return spring 34 are respectively connected to the ratchet 31 and the pawl 33.

[0045] Figure 3 When the force-bearing portion 18 of the middle support plate 4 rotates clockwise, the ratchet 31 is pressed down, so that the ratchet 31 can hook the limiting tube 7, so that the support plate 4 remains inclined, which can reduce the possibility of the human body's hips moving forward, prevent the occupant's body from moving down, and allow the safety belt to restrain the pelvic area of ​​the occupant, thereby protecting the safety of the occupant.

[0046] In some specific implementations, a ratchet 31 protrusion is provided on the ratchet 31 , and a ratchet 33 hook is provided on the pawl 33 ; the ratchet 33 hook is matched with the ratchet 31 protrusion.

[0047] In some specific embodiments, a traction member is further included; the traction member includes a connecting member 21 and a fixing member 22 and a sleeve 23 sleeved on the connecting member 21, the fixing member 22 is respectively connected to the mounting plate 32 and the sleeve 23, one end of the connecting member 21 is connected to the pawl 33, and the other end is connected to the driving member. Pulling the connecting member 21 drives the pawl 33 to rotate through the connecting member 21, and after rotating a certain angle, the pawl 33 hooks and disengages from the protrusion of the ratchet 31. The ratchet 31 rotates under the action of the ratchet spring and returns to the unlocked state. After releasing the connecting member 21, the pawl 33 returns to the initial state under the action of the pawl spring.

[0048] The driving member can be a pull ring, or a buckle, etc. The fixing member 22 can be a fixing plate, or a bracket.

[0049] In some specific embodiments, the limiting portion 211 is provided with a groove, and the limiting tube 7 is arranged in the groove for contacting with the limiting portion 211. When the ratchet 31 of the first locking mechanism and the second unlocking mechanism is unlocked, the blocking portion 17 moves toward the direction close to the floor under the action of the tension of the elastic member, and the force-bearing portion 18 is lifted upward, that is, from Figure 4 The blocking portion 17 rotates counterclockwise to restore the support plate 4 to the Figure 3 When in the middle state, the fiber tube abuts against the groove to prevent the blocking portion 17 from rotating too much under the pulling force of the first elastic member 12 and the second elastic member 14.

[0050] In some specific embodiments, the blocking portion 17 is provided with a round tube 5, the round tube 5 is provided with a support plate 16, and the first elastic member 12 and the second elastic member 14 are both connected to the support plate 16. After the blocking portion 17 is lifted, the support plate 4 is tilted, and the round tube 5 can reduce the possibility of the human body's hips moving forward, prevent the occupant's body from moving down, and allow the safety belt to restrain the pelvic area of ​​the occupant, thereby protecting the safety of the occupant.

[0051] In some specific embodiments, such as Figure 1 and Figure 2 As shown, the first locking mechanism and the second locking mechanism are installed on the mounting base using the mounting nut 9, and then the bushing 10 is fixed to the mounting base, the round tube 5, the welding nut 6, and the limit tube 7 are welded to the support plate 4, and the support plate 4 is connected to the mounting base using the step bolt 11. Finally, the first elastic member 12 and the second elastic member 14 are installed between the support plate 4 and the mounting base, and are fixed to the vehicle body 13 using the mounting bolt 1.

[0052] When the vehicle is running normally, the round tube 5 is in a normal and comfortable position, such as Figure 3 As shown; when a vehicle collides head-on, the human buttocks move forward under the action of inertia. At this time, the limiting tube 7 is subjected to the pressure of the human buttocks, causing the support plate 4 to rotate counterclockwise around the step bolt 11, and the round tube 5 moves upward. At the same time, the limiting tube 7 is locked downward by the right ratchet 31 and the left ratchet 31. At this time, under the action of the lifting of the round tube 5, the human buttocks are prevented from moving forward, thereby protecting the safety of the passengers. After the collision, the unlocking traction member is pulled, and under the pulling force of the elastic member, the support plate 4 rotates clockwise around the step bolt 11, so that the round tube 5 and the limiting tube 7 return to the designed position.
