Abstract
Description
Technical Field
[0001] The present application relates to the technical field of automobiles, and particularly to a seat and a vehicle. Background Art
[0002] When a vehicle is rear-ended, since the occupant's torso is first affected by the vehicle and moves forward with an acceleration, while the head lags behind relatively due to inertia, the occupant's head rotates backward, causing neck injuries. This type of injury is similar to the action of a whip, so it is called "whiplash injury".
[0003] In order to reduce the injuries suffered by passengers when a vehicle is rear-ended, a backrest lock is usually provided on the side of the seat. The backrest lock can fix the angle between the seat backrest and the base. In this way, when the vehicle is rear-ended, after the passenger impacts on the seat backrest, the seat backrest will not rotate, and the distance between the passenger's head and the headrest will not increase, which can effectively reduce the whiplash injury suffered by the passenger.

Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0028] With the booming development of the automotive industry, the number of automobiles in use is constantly increasing, and the number of vehicle collision accidents is also showing an upward trend.
[0029] When the vehicle is impacted from the rear, since the seat back moves forward relative to the human back, the arcuate spine in the normal state is pushed straight by the forward thrust from the seat back, and the straightening of the spine from a bent state drives the human head to rise vertically.
[0030] When the seat back collides with the back of the passenger, the back of the passenger will generate a backward thrust on the seat back. When the seat back is not firmly fixed to the seat base, the seat back will flip backward. In this way, the distance between the passenger's head and the seat headrest increases, and the passenger's head lacks support. Under the action of inertia, the passenger's head swings like a whip, and the violent change in the neck causes injuries to the neck and its soft tissues.
[0031] In order to reduce the whiplash injury suffered by the passenger when the vehicle is impacted from the rear, a backrest lock is usually provided on the side of the seat. The backrest lock can fix the angle between the seat back and the seat base. After the back of the passenger collides with the seat back, the seat back will not rotate, the distance between the passenger's head and the seat headrest will not change, and the seat headrest can support the passenger's head, thereby reducing the whiplash injury suffered by the passenger.
[0032] In the existing seats, the backrest lock is usually provided only on one side of the seat. When the vehicle is rear-ended, the backrest lock restricts the rotation of the seat back from one side of the seat. The forces on both sides of the seat back are uneven, the backrest lock is easily damaged, the seat back is easily shaken, and the passenger is easily injured.
[0033] Based on this, the embodiment of the present application provides a vehicle, which may include a vehicle body and a seat. Among them, an occupant compartment can be formed inside the vehicle body, and the occupant compartment can provide a seating space for the user. The seat can be arranged on the vehicle body and located inside the occupant compartment of the vehicle body.
[0034] It can be understood that the vehicle provided by the embodiment of the present application may further include other components, such as an engine, a transmission mechanism, etc., to realize the basic functions of the vehicle.
[0035] Next, the seat provided by the embodiment of the present application will be further introduced, as Figure 1 shown, Figure 1 is one of the structural schematic diagrams of the seat 100 provided by the embodiment of the present application. The seat 100 may include a base frame 1 and a seat back 2. When a passenger sits on the seat 100, the base frame 1 and the seat back 2 can support the passenger. A seat headrest (not shown in the figure) is usually provided at the top of the seat back 2, and the seat headrest can support the head of the passenger.
[0036] The seat backrest 2 is rotatably connected to the base frame 1. During actual application, passengers can adjust the setting angle of the seat backrest 2 according to actual needs.
[0037] As Figure 1 shown, the seat 100 may further include a locking member 3 and a limiting member 4. The locking member 3 is connected to the seat backrest 2. In this way, the locking member 3 can rotate together with the rotation of the seat backrest 2.
[0038] The limiting member 4 is rotatably connected to the base frame 1 and is used to rotate under the action of inertia and engage with the locking member 3. During actual application, when the vehicle is rear-ended, the limiting member 4 can engage with the locking member 3 under the action of inertia. As the limiting member 4 engages with the locking member 3, the limiting member 4 and the locking member 3 can limit the rotation of the seat backrest 2 relative to the base frame 1, so that the seat headrest can support the passenger's head during the collision, thereby reducing the whiplash injury suffered by the passenger.
[0039] Exemplarily, during actual application, a backrest lock can be provided on one side of the seat 100, and the limiting member 4 and the locking member 3 can be provided on the other side. When the vehicle is rear-ended, the backrest lock restricts the rotation of the seat backrest from one side of the seat 100, and the limiting member 4 and the locking member 3 can restrict the rotation of the seat backrest from the other side of the seat 100. When the seat 100 is impacted, the seat backrest 2 is evenly stressed on both sides, and the seat backrest 2 is not likely to rotate.
[0040] When the vehicle is in a normal state, the limiting member 4 does not rotate, and the limiting member 4 and the locking member 3 are in a separated state. At this time, the limiting member 4 and the locking member 3 do not restrict the rotation of the seat backrest 2, and the passenger can unlock the single-sided backrest lock to rotate the seat backrest 2 to adjust the seat backrest 2 to a comfortable angle.
[0041] In order to ensure that the limiting member 4 can engage with the locking member 3 when the vehicle is rear-ended, in some embodiments, as Figure 1 shown, the first end of the limiting member 4 is rotatably connected to the base frame 1, and the second end is used to engage with the locking member 3.
[0042] The seat 100 may further include a retaining member 5. The retaining member 5 is connected to the base frame 1, and a part of the retaining member 5 is located on the side of the limiting member 4 away from the locking member 3 and abuts against the limiting member 4. In this way, the retaining member 5 can limit the limiting member 4 in a position to prevent the limiting member 4 from rotating away from the locking member 3 under the action of gravity.
[0043] Along the extending direction of the limiting member 4, a part of the retaining member 5 is located between the first end and the second end. The limiting member 4 is inclined, and along the arrangement direction of the limiting member 4 and the locking member 3, the second end is located on the side of the first end close to the locking member 3.
[0044] In this way, the retaining member 5 can keep the limiting member 4 in a state where the second end is inclined towards the locking member 3, and the center of gravity of the limiting member 4 can be located on the side of the rotation axis of the limiting member 4 close to the locking member 3. Thus, when the limiting member 4 rotates under the action of inertia, the second end of the limiting member 4 can rotate towards the position where the locking member 3 is located, so as to be engaged with the limiting member 4.
[0045] Exemplarily, as Figure 1 shown, the limiting member 4 can be located below the locking member 3. The first end of the limiting member 4 is located on the Figure 1 left side in Figure 1 , and the second end of the limiting member 4 is located on the Figure 1 right side in Figure 1 , and the limiting member 4 is inclined towards the upper right in
[0046] . The retaining member 5 can be located below the limiting member 4. The self-gravity of the limiting member 4 causes the limiting member 4 to have a tendency to rotate clockwise in Figure 1 , and the retaining member 5 can prevent the limiting member 4 from rotating under its own gravity. Figure 1 At this time, the center of gravity of the limiting member 4 is located above the rotation axis of the limiting member 4. When the vehicle is impacted from the rear, the limiting member 4 rotates counterclockwise in Figure 1 under the action of inertia. As the limiting member 4 rotates counterclockwise in
[0047] , the second end of the limiting member 4 can be engaged with the locking member 3, thereby restricting the seat back 2 from rotating counterclockwise in Figure 1 shown, when the second end of the limiting member 4 is engaged with the locking member 3 under the action of inertia, the limiting member 4 still remains in a state of being inclined towards the upper right in Figure 1 . After the collision, the limiting member 4 can rotate clockwise in Figure 1 under the action of gravity, so as to be separated from the locking member 3. At this time, the seat back 2 can rotate normally.
[0048] In some other embodiments, the rotation axis of the limiting member 4 can be located between the first end and the second end of the limiting member 4, the center of gravity of the limiting member 4 is located on the side of the rotation axis close to the locking member 3, and when the seat is installed on the vehicle, the center of gravity of the limiting member 4 is located on the side of the first end close to the vehicle head. In this way, when the rear part of the vehicle is impacted, the second end of the limiting member 4 can also rotate towards the direction close to the locking member 3 under the action of inertia and be engaged with the locking member 3.
[0049] In order to achieve the engagement between the limiting member 4 and the locking member 3, in some embodiments, as Figure 1As shown, a hook 41 is formed at the second end of the limiting member 4, and a clamping portion 31 is formed on the locking member 3. The hook 41 is used to be clamped with or separated from the clamping portion 31. In this way, when the hook 41 is clamped with the clamping portion 31, the locking member 3 and the limiting member 4 can limit the rotation of the seat backrest 2.
[0050] Exemplarily, as Figure 1 shown, the second end of the limiting member 4 is bent obliquely upward to the left to form the hook 41. The locking member 3 is located on the Figure 1 right side surface of the lower right end in the Figure 1 and is recessed to the left to form the clamping portion 31. When the limiting member 4 rotates counterclockwise along the Figure 1 in the Figure 1 the hook 41 can rotate into the clamping portion 31. As the hook 41 abuts against the clamping portion 31, the limiting member 4 and the locking member 3 can limit the seat backrest 2 from rotating counterclockwise along the
[0051] During the impact, the back of the passenger will continuously exert an external force on the seat backrest 2, and the seat backrest 2 has a tendency to rotate counterclockwise along the Figure 1 in the
[0052] In this way, the clamping portion 31 can maintain the state of abutting against the hook 41, and the hook 41 will not be separated from the clamping portion 31. Therefore, during the rear impact of the vehicle, the hook 41 and the clamping portion 31 can remain in the clamped state, and the limiting member 4 and the locking member 3 can continuously limit the rotation of the seat backrest 2. Figure 1 After the impact, the back of the passenger no longer exerts a thrust on the seat backrest 2, and the seat backrest 2 no longer has a tendency to rotate counterclockwise along the Figure 1 in the
[0053] In some embodiments, in order to facilitate the installation of the limiting member 4 on the base frame 1, as Figure 1 shown, the seat 100 may further include a mounting member 6. The mounting member 6 is connected to the base frame 1, and the first end of the limiting member 4 is rotatably connected to the mounting member 6.
[0054] In this way, the staff can first rotatably connect the limiting member 4 to the mounting member 6, and then set the mounting member 6 on the base frame 1. When the limiting member 4 is connected to the mounting member 6, it will not be interfered and affected by other components on the base frame 1, and it is convenient for the staff to rotatably connect the limiting member 4 and the mounting member 6 together.
[0055] AsFigure 1 As shown, the retaining member 5 is connected to the mounting member 6. In this way, it can be ensured that the retaining member 5 can abut against the limiting member 4.
[0056] In order to facilitate the installation of the mounting member 6 on the base frame 1, in some embodiments, the mounting member 6 is welded to the base frame 1. During actual application, there is no need to additionally process holes or other connection structures on the base frame 1. Just place the mounting member 6 at a suitable position on the base frame 1, and then connect the mounting member 6 to the base frame 1 by welding.
[0057] Exemplarily, as Figure 1 shown, along the Figure 1 left - right direction in
[0058] In order to realize the rotational connection between the limiting member 4 and the mounting member 6, in some embodiments, as Figure 2 shown, Figure 2 FIG. 2 is a second schematic structural view of the seat 100 provided by the embodiment of the present application. The seat 100 further includes a rotating member 7, and a connecting portion 42 is formed on the limiting member 4. One end of the rotating member 7 is connected to the mounting member 6, and the other end is rotatably connected to the connecting portion 42. In this way, the rotational connection between the limiting member 4 and the mounting member 6 can be realized.
[0059] It can be understood that the limiting member 4 can also be rotatably connected to the mounting member 6 in other ways. For example, a protruding portion can be formed on the limiting member 4, and the protruding portion is cylindrical. A rotating groove is formed on the mounting member 6, and the protruding portion of the limiting member 4 is inserted into the rotating groove. In this way, the rotational connection between the limiting member 4 and the mounting member 6 can also be realized.
[0060] In some embodiments, as Figure 2 shown, the connecting portion 42 is a connecting hole, and the rotating member 7 can be a rotating shaft. The rotating shaft passes through the connecting hole, one end is connected to the mounting member 6, and the other end is rotatably connected to the limiting member 4. In this way, the rotational connection between the rotating member 7 and the limiting member 4 can be realized.
[0061] In other embodiments, one end of the rotating member 7 can be connected to the limiting member 4, and the other end is rotatably connected to the mounting member 6. In this way, the rotational connection between the limiting member 4 and the mounting member 6 can also be realized.
[0062] In some embodiments, as Figure 2As shown, a plurality of mounting portions 32 are formed on the locking member 3, and the seat 100 may further include a plurality of connecting members 8. One end of each of the plurality of connecting members 8 is connected to the mounting portion 32, and the other end is connected to the seat backrest 2. In this way, the plurality of connecting members 8 can fix the locking member 3 and the seat backrest 2 together from different positions, preventing the locking member 3 from rotating.
[0063] In some embodiments, as Figure 2 shown, the mounting portion 32 may be a mounting perforation, and the connecting member 8 may be a rivet. A plurality of rivets are inserted into the plurality of mounting holes, with one end abutting against the side of the locking member 3 away from the seat backrest 2 and the other end riveted to the seat backrest 2. In this way, the locking member 3 can be fixed to the seat backrest 2.
[0064] It can be understood that the locking member 3 can also be connected to the seat backrest 2 in other ways, as long as it is ensured that the locking member 3 can rotate with the seat backrest 2 and there is no relative rotation between the locking member 3 and the seat backrest 2. For example, the locking member 3 can also be connected to the seat backrest 2 by welding.
[0065] As described above, the above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
