[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art based on the embodiments of the utility model belong to the protection scope of the utility model.
[0024] Referring to Figures 1-2 The embodiment provides a seat collapse reset structure of a vehicle, which comprises a collapse reset member 1.
[0025] One end of the collapse reset member 1 is provided with a rotating hole 11, the collapse reset member 1 is rotationally connected with a front end support 3 hinged below a vehicle seat 2 through a rotating member 31 arranged in the rotating hole 11, and the other end of the collapse reset member 1 is used for being connected with a vehicle floor 4.
[0026] The collapse reset member 1 is provided with a collapse notch 12, the collapse notch 12 is located below the rotating hole 11, and the rotating member 31 can be moved downward from the rotating hole 11 into the collapse notch 12 and move downward along the collapse notch 12 in the collapse notch 12 under the action of an external force, so as to drive the front end support 3 to move downward, and drive the vehicle seat 2 in a lying posture to move downward to a sitting posture under the driving of the front end support 3.
[0027] When being specifically implemented, referring to Figure 1 The top end of the collapse reset member 1 is provided with the rotating hole 11, the rotating member 31 is arranged in the rotating hole 11 and the front end support 3, so as to realize the hinging of the collapse reset member 1 and the front end support 3, and the bottom end of the collapse reset member 1 is connected with the vehicle floor 4.
[0028] When the vehicle does not collide, the rotating member 31 can be stably arranged in the rotating hole 11 to rotationally connect with the front end support 3, so that the front end support 3 can reliably support the vehicle seat 2, and the lying angle of the vehicle seat 2 can be switched by adjusting the rotating angle of the front end support 3 relative to the collapse reset member 1 or adjusting the length of the front end support 3, so as to meet the requirements of different use scenarios.
[0029] When the vehicle is in a collision and needs to quickly switch the vehicle seat 2 in a lying posture to a sitting posture, at this time the rotating piece 31 will collapse downward under the action of external collision impact, and move from the rotating hole 11 to the collapse notch 12 and move downward in the collapse notch 12 for collapse, at this time the entire front end support 3 will be driven by the rotating piece 31 to move downward, and finally drive the front end of the vehicle seat 2 to move downward, so that the vehicle seat 2 can be reset from the lying posture to the sitting posture.
[0030] That is, when the front end support 3 moves downward, the front end of the vehicle seat 2 supported by the front end support 3 will also move downward, and then the front end of the vehicle seat 2 can move downward to be flush with the rear end of the vehicle seat 2, that is, the entire seat cushion of the vehicle seat 2 can be in a substantially horizontal state, at this time the vehicle seat 2 is in a sitting posture.
[0031] In the embodiment, by allowing the rotating piece 31 to collapse on the collapse reset piece 1 when subjected to external collision impact, the posture switching of the vehicle seat 2 can be achieved, and the entire structure is not only simple but also responds quickly. Compared with the way of needing to judge in advance whether the vehicle is in a collision, and then driving the vehicle seat 2 to switch to a sitting posture by a seat motor, the response of the embodiment is faster, and therefore the safety is higher.
[0032] It should be noted that when the rotating piece 31 moves to the bottom end of the collapse notch 12, at this time it can be considered that the entire seat cushion of the vehicle seat 2 can be in a substantially horizontal state.
[0033] Exemplarily, the rotating piece 31 can be a rotating shaft or a bolt, and the front end support 3 is also provided with a through hole matched with the rotating piece 31, so as to realize the rotating cooperation of the front end support 3 and the collapse reset piece 1.
[0034] Exemplarily, the collapse reset piece 1 can be made of metal or alloy material, so as to have sufficient structural strength, so that the rotating piece 31 can be reliably located in the rotating hole 11 without moving downward when no collision occurs.
[0035] Exemplarily, the shape of the collapse notch 12 can be rectangular, trapezoidal or elliptical, etc.
[0036] Exemplarily, the vehicle seat 2 in the embodiment can be a zero-gravity seat, that is, it can have a lying posture to enable the occupant to lie flat.
[0037] The seat collapse reset structure of the vehicle of the embodiment comprises a collapse reset piece 1, one end of the collapse reset piece 1 is provided with a rotating hole 11, the collapse reset piece 1 is rotationally connected with a front end support piece 3 hinged below a vehicle seat 2 through a rotating piece 31 penetrating in the rotating hole 11, so as to realize the rotationally connecting of the collapse reset piece 1 with the front end support piece 3, the other end of the collapse reset piece 1 is used to connect with a vehicle floor 4. By providing the collapse reset piece 1 with a collapse notch 12, the collapse notch 12 is arranged below the rotating hole 11, so that when the vehicle is subjected to a collision, the rotating piece 31 is moved downward from the rotating hole 11 to the collapse notch 12 and moves downward in the collapse notch 12 under the impact of the external collision force, so as to drive the front end support piece 3 to move downward, and then the vehicle seat 2 in a lying posture is rapidly moved downward to a sitting posture under the driving of the front end support piece 3, so as to realize the rapid reset of the vehicle seat 2, and the whole structure is simple and the reset response is relatively rapid.
[0038] Referring to Figure 1 As shown in the figure, in some embodiments, the collapse notch 12 is communicated with the rotating hole 11, and the diameter of the end of the collapse notch 12 communicated with the rotating hole 11 is smaller than the inner diameter of the rotating hole 11.
[0039] When the collapse notch 12 is communicated with the rotating hole 11, at this time when the vehicle is subjected to a collision, the rotating piece 31 in the rotating hole 11 can be rapidly moved downward to the collapse notch 12 communicated with the rotating hole 11 and moved downward in the collapse notch 12, so as to realize the collapse operation of the rotating piece 31 on the collapse reset piece 1, and the whole process is smooth and the response is relatively fast.
[0040] When the collapse notch 12 is communicated with the rotating hole 11, in order to ensure that the rotating piece 31 can reliably be in the rotating hole 11 to realize the reliable support of the front end support piece 3 to the vehicle seat 2 without easily moving downward to the collapse notch 12 when it is not necessary to reset to the sitting posture, the diameter of the end of the collapse notch 12 communicated with the rotating hole 11 can be smaller than the inner diameter of the rotating hole 11, at this time the rotating piece 31 cannot move downward to the collapse notch 12 from the rotating hole 11.
[0041] Alternatively, in other implementations, the collapse notch 12 can also be not communicated with the rotating hole 11, and the two can be separated by a weak strength partition, so that when it is not necessary to reset the vehicle seat 2, the rotating piece 31 can be limited by the partition to prevent it from moving downward to the collapse notch 12 and affecting the reliable support of the front end support piece 3 to the vehicle seat 2. When the vehicle is subjected to a collision, at this time the rotating piece 31 is subjected to a larger external collision impact, so it can quickly break through the partition and then move downward to the collapse notch 12.
[0042] Further, in order to make the rotating member 31 break through the partition more easily, a weakened area can be provided on the partition, that is, the thickness of the portion of the partition corresponding to the rotating member 31 can be smaller than the thickness of other areas of the partition.
[0043] Referring to Figure 1 As shown, the length extension direction of the collapse notch 12 is parallel to the moving direction of the rotating member 31, and such arrangement can make the rotating member 31 move into the collapse notch 12 under the external impact force and move downward in the collapse notch 12 smoothly and without deviation, so as to finally achieve the purpose of switching the vehicle seat 2 to the sitting posture.
[0044] Referring to Figure 1 As shown, in some embodiments, the caliber of the collapse notch 12 gradually decreases in the direction from the rotating hole 11 to the collapse notch 12.
[0045] That is, the caliber of the collapse notch 12 gradually decreases in the direction from top to bottom, and such arrangement can make the structural strength of the collapse reset member 1 gradually increase in the direction from top to bottom, so as to gradually reduce the collapse speed of the rotating member 31 during the downward movement of the rotating member 31 in the collapse notch 12, thereby achieving controllable collapse speed and making the rotating member 31 finally move downward to the preset position smoothly.
[0046] In addition, in the present embodiment, since the collapse reset member 1 is provided with the collapse notch 12, the collapse reset member 1 can also deform to a certain extent when the vehicle collides, thereby absorbing the impact force in the collision, so as to further improve the safety performance.
[0047] Referring to Figure 1 As shown, in some embodiments, the extension size of the collapse notch 12 is greater than the inner diameter of the rotating hole 11 in the direction from the rotating hole 11 to the collapse notch 12.
[0048] Such arrangement can make the collapse notch 12 have sufficient extension size in the up-down direction, so as to make the rotating member 31 have sufficient collapse stroke, that is, downward movement stroke, in the collapse notch 12, thereby achieving the purpose of finally switching the vehicle seat 2 to the sitting posture.
[0049] For example, the extension size L of the collapse notch 12 in the direction from the rotating hole 11 to the collapse notch 12 and the inner diameter d of the rotating hole 11 satisfy: L≥2d.
[0050] By reasonably setting the ratio of the size L of the collapse notch 12 in the up-down direction and the inner diameter d of the rotating hole 11, it can be ensured that the rotating member 31 has sufficient collapse stroke, and the collapse displacement amount of the rotating member 31 can be adjusted by controlling the size L of the collapse notch 12 in the up-down direction.
[0051] For example, L=2d can be set, or L>2d can be set, and the specific ratio can be set according to the actual required collapse stroke, and the embodiment is not limited thereto.
[0052] Referring to Figure 1 In some embodiments, at least one side of the collapse gap 12 in the direction from the front end of the vehicle seat 2 to the rear end of the vehicle seat 2 is provided with a weakening structure 13.
[0053] The direction from the front end of the vehicle seat 2 to the rear end of the vehicle seat 2 can refer to the x direction shown in Figure 2 By providing a weakening structure 13 on at least one side of the collapse gap 12, the safety performance of the vehicle can be further improved when the vehicle is in a collision by deforming at the weakening structure 13 to absorb the impact force generated by the collision.
[0054] For example, the weakening structure 13 can be provided on only one side of the collapse gap 12, or the weakening structure 13 can be provided on both sides of the collapse gap 12. When the weakening structure 13 is provided on both sides of the collapse gap 12, the two weakening structures 13 can be symmetrically arranged relative to the center axis of the collapse gap 12, so that the manufacturing process of the entire collapse reset member 1 is simpler, and the structural strength of the regions on both sides of the collapse gap 12 of the collapse reset member 1 is more balanced, so that the collapse reset member 1 can deform uniformly as a whole to better absorb the impact force when the vehicle is in a collision.
[0055] Referring to Figure 1 In some embodiments, the weakening structure 13 can be a weakening gap, and the caliber of the weakening gap gradually decreases in the direction from the rotating hole 11 to the collapse gap 12.
[0056] In this way, the structural strength of the collapse reset member 1 in the direction from top to bottom is higher, and then the collapse speed of the rotating member 31 gradually decreases during the downward movement of the rotating member 31 in the collapse gap 12, so as to realize the controllable collapse speed.
[0057] For example, in the present embodiment, the weakening gap and the collapse gap 12 can be arranged not to communicate with each other, so that the rotating member 31 can smoothly move downward into the collapse gap 12 for collapse, and will not move into the weakening gap due to offset movement, so as to ensure that the front end support 3 can smoothly move downward to drive the vehicle seat 2 to move downward to the seating posture.
[0058] For example, in other implementations, the weakening structure can be a thickness reduction structure, that is, a part of the collapse reset member 1 is arranged to have a smaller thickness, so as to facilitate deformation in this area.
[0059] Referring to Figures 1-2 As shown in the figure, the embodiment further provides a seat assembly, which comprises the vehicle seat 2, the front end support 3, the rotating member 31 and the seat collapse reset structure of the vehicle as described above.
[0060] Specifically, the seat assembly further comprises a rear end support 5 located below the vehicle seat 2, which is located on the side of the front end support 3 close to the parking space of the vehicle and is connected with the vehicle seat 2 and the vehicle floor 4 respectively, so that the vehicle seat 2 can be reliably in the required use posture through the cooperation of the front end support 3 and the rear end support 5.
[0061] For example, the end of the front end support 3 away from the collapse reset member 1 can be screwed or welded with the vehicle seat 2, and the end of the collapse reset member 1 away from the front end support 3 can be welded or screwed with the vehicle floor 4. The two ends of the rear end support 5 can be welded or screwed with the vehicle seat 2 and the vehicle floor 4 respectively.
