DETAILED DESCRIPTION

[0038] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0039] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0040] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0041] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0042] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0043] It should be noted that in the following description, "positive" and "negative" are relative concepts, which are only used to indicate that the seat has opposite movement directions. The positive direction can refer to the direction from the rear to the front of the vehicle, and the negative direction can refer to the direction from the front to the rear of the vehicle, or vice versa.

[0044] like Figures 1 to 10 As shown, the seat blocking mechanism in this embodiment includes: a seat 1, which can be at a first tilt angle; a stopping mechanism 2; when the seat 1 is at the first tilt angle, the positive movement of the seat 1 can drive the stopping mechanism 2 to move to release the blocking of the seat 1, and the negative movement of the seat 1 can be blocked by the stopping mechanism 2.

[0045] Specifically, Figure 7 As shown, when the ground lock 5 releases the lock on the seat 1, the seat 1 is at a first tilt angle β, and the seat 1 is in a raised state. Figure 7 The first inclination angle β in φ may be the angle between the seat surface L2 and the horizontal plane L1 , or may refer to the angle between the seat back and the horizontal plane.

[0046] like Figure 7 , Figure 8 and Fig. 9 As shown, when the seat 1 is in the first tilt angle state, during the forward movement of the seat 1, the forward movement of the seat 1 can drive the stop mechanism 2 to move to release the blocking of the limiter 101, so the forward movement of the seat 1 is not blocked by the stop mechanism 2, while the negative movement of the seat 1 can be blocked by the stop mechanism 2. In the seat blocking mechanism of this embodiment, even when the floor lock 5 does not lock the seat 1, the seat 1 can still move forward to facilitate the entry and exit of people, thereby improving the convenience of the members entering and exiting the vehicle, while the negative movement will be blocked to prevent the feet of the rear seat members from being injured, thereby ensuring the safety of the members.

[0047] like Figure 7 and Fig. 9 As shown, the seat 1 is provided with a limiting member 101 , and when the seat 1 is in a first tilt angle β state, the limiting member 101 can contact the stop mechanism 2 .

[0048] Specifically, the stopper 101 may be a component installed on the seat 1 or other positions, or may be a structure of the seat 1 itself, such as a flange of the seat 1 itself. The stopper 101 may be a rod, a plate, or a flange mechanism of the seat 1 itself. Figure 7 and Fig. 9As shown, when the seat 1 is at the first tilt angle β, the limiter 101 is at a lower position due to the rotation of the seat 1, so the limiter 101 can contact the stop mechanism 2 during the positive and negative movement of the seat 1. This structure can prevent the limiter 101 or the stop mechanism 2 from being worn during the normal forward and backward adjustment of the seat 1.

[0049] like Figure 1 , Figures 7 to 10 As shown, in this embodiment, the seat blocking mechanism also includes a first slide rail 301, the seat 1 slides positively or negatively through the first slide rail 301, and the seat 1 can rotate relative to the first slide rail 301, the seat 1 includes a seat body 102 and a seat connecting rod 4 arranged on the seat body 102, one end of the seat connecting rod 4 is hinged to the first slide rail 301, and one end of the seat connecting rod 4 is provided with the limiting member 101.

[0050] Specifically, the seat blocking mechanism can use the slide rail assembly 3 to achieve positive movement and negative movement. The seat 1 and the floor lock 5 can be installed on the slide rail assembly 3, and the slide rail assembly 3 is installed on the vehicle body floor, so the seat 1 and the floor lock 5 can slide positively or negatively. For example, the slide rail assembly 3 may include a first slide rail 301 and a second slide rail 302, and the first slide rail 301 and the second slide rail 302 are slidably matched. The seat 1 is installed on the first slide rail 301, and the second slide rail 302 is installed on the vehicle (such as the vehicle body floor). The first slide rail 301 slides relative to the second slide rail 302, so that the seat 1 slides positively or negatively. The seat 1 can also rotate relative to the first slide rail 301, so that the seat 1 is at a first tilt angle β or a second tilt angle α. In the second tilt angle α state, the occupant can sit on the seat 1 normally. The seat 1 may include a seat body 102 and a seat armrest that can rotate relative to the seat body 102. The seat link 4 is arranged on the seat body 102, so when the tilt angle or the positive or negative position of the seat 1 changes, the seat link 4 will move with the movement of the seat body 102. One end of the seat link 4 is hinged to the first slide rail 301, and a limiter 101 is arranged on one end of the seat link 4, so when the seat 1 rotates from the second tilt angle α to the first tilt angle β, the seat link 4 will rotate, thereby driving the movement of the limiter 101, so that the limiter 101 can enter from a height that does not contact the stop mechanism 2 to a height that can contact the stop mechanism 2. The hinge between the seat link 4 and the seat 1 and the first slide rail 301 can be directly connected or indirectly connected through a connecting plate or other mechanism. The advantage of arranging the limiter 101 on the seat link 4 is that during the rotation, positive or negative movement of the seat 1, the limiter 101 can automatically reach or exit the height that cooperates with the stop mechanism 2, and the structure is simple.

[0051] like Figure 2 and Figure 3 As shown, in this embodiment, the stop mechanism 2 includes a pressing block 201 and a first return spring 202 connected to the pressing block 201, and the first return spring 202 is used to restore the pressing block 201 to an initial state. The pressing block 201 has a first guide surface 203 and a blocking surface 212. When the seat 1 is at the first tilt angle β, the limiting member 101 can press against the first guide surface 203 to compress the first return spring 202 when moving in a positive direction, and can be blocked by the blocking surface 212 when the limiting member 101 moves in a negative direction.

[0052] Specifically, in Figure 2 In the embodiment, the seat 1 is at the first tilt angle β and is moving in the positive direction, and the stopper 101 begins to contact the first guide surface 203. Figure 3 In the embodiment, the seat 1 is at the first tilt angle β and continues to move forward, the stopper 101 presses against the first guide surface 203, and the first return spring 202 is compressed. As the seat 1 continues to move forward, the stopper 101 will pass over the pressing block 201, and the elastic force of the first return spring 202 will restore the pressing block 201 to its initial state. At this time, if the seat 1 is at the first tilt angle β and moves negatively, the stopper 101 will be blocked by the blocking surface 212 of the pressing block 201. The first return spring 202 can be installed on the vehicle body floor or other suitable positions. This telescopic stopper mechanism 2 has a simple structure and occupies little space.

[0053] like Figure 3 As shown, the blocking surface 212 is parallel to the expansion and contraction direction of the first return spring 202 , and the movement direction of the pressing block 201 is the same as the expansion and contraction direction of the first return spring 202 .

[0054] Specifically, although Figure 3 The blocking surface 212 is shown as a line segment, but in reality the blocking surface 212 is a plane. The blocking surface 212 is parallel to the expansion and contraction direction of the first return spring 202, which means that the two are in a line-plane parallel relationship. This structure allows the blocking surface 212 of the pressure block 201 to always face the limiter 101 during the expansion and contraction process of the first return spring 202, preventing the limiter 101 from moving back in the negative direction after passing over the pressure block 201. The movement direction of the pressure block 201 is the same as the expansion and contraction direction of the first return spring 202. For example, the pressure block 201 and the first return spring 202 can be installed under the vehicle body floor and only the pressure block 201 is exposed from the vehicle body floor. At this time, the pressure block 201 can be pressed by the limiter 101 and shrink toward the vehicle body floor. After the limiter 101 passes over the first guide surface 203, the pressure block 201 will rebound under the elastic force of the first return spring 202, so that the blocking surface 212 can play a role in blocking the negative movement of the limiter 101.

[0055] like Figure 4 and Figure 5 As shown, the present embodiment adopts a rotary stop mechanism 2. The stop mechanism 2 comprises a fixing member 204 and a stop member 205, wherein the stop member 205 is rotationally matched with the fixing member 204, and the stop member 205 can rotate unidirectionally to release the blocking of the positive movement of the limiting member 101.

[0056] Specifically, the step rivet 210 passes through the through holes on the fixing member 204 and the stopper 205, and the step rivet 210 is covered with a bushing 211. After the step rivet 210 is riveted, the stopper 205 can rotate unidirectionally relative to the fixing member 204. Here, unidirectional rotation means that the stopper 205 can only rotate in one direction (for example, in the initial state) relative to the initial state. Figure 7 The second direction in the figure) can be rotated or restored to the initial state, but cannot be rotated in another direction (for example Figure 7 The fixing member 204 can be mounted on the slide rail assembly 3 or the vehicle body floor, and the one-way rotation of the stopper 205 can be limited by the vehicle body floor or the surrounding structure.

[0057] like Figure 4 and Figure 7 As shown, the stopper 205 has a second guide surface 206 , and when the limiting member 101 moves in the forward direction, it can abut against the second guide surface 206 to make the stopper 205 rotate in one direction.

[0058] Specifically, Figure 7 As shown, when the seat 1 is at the first tilt angle β, when the seat 1 moves in the positive direction, the limiting member 101 abuts against the second guide surface 206, driving the stop member 205 to rotate in one direction to pass through the stop mechanism 2. However, when the seat 1 moves in the negative direction, since the stop member 205 cannot rotate in the first direction, the limiting member 101 will be blocked by the stop member 205, and the negative movement of the seat 1 is blocked.

[0059] like Figure 4 and Figure 5 As shown, a second return spring 207 is provided between the fixing member 204 and the stop member 205 , and the second return spring 207 is used to restore the stop member 205 to an initial state.

[0060] Specifically, Figure 7 and Figure 8 As shown, after the limiter 101 moves forward over the stopper 205, the second return spring 207 pulls the stopper 205 back to the initial state under the elastic force. Alternatively, the stopper 205 can also automatically return to the initial state under the action of gravity through the design of the center of gravity.

[0061] like Figure 4 and Figure 5 As shown, the fixing member 204 has a first arm 208 , and the first arm 208 can limit the rotation angle of the stopper 205 .

[0062] More specifically, Figure 6 Taking the installation of the middle fixing member 204 on the slide rail assembly 3 as an example, the rotation angle of the stop member 205 is limited by the first arm 208 on the fixing member 204 . If the rotation angle of the stop member 205 is too large, it will be blocked by the first arm 208 .

[0063] like Figure 4 and Figure 5 As shown, the stopper 205 has a second arm 209 , and the second return spring 207 is arranged between the first arm 208 and the second arm 209 , and the second return spring 207 is used to restore the stopper 205 to an initial state.

[0064] Specifically, the two ends of the second return spring 207 can be connected to the first arm 208 and the second arm 209 respectively. After the limit member 101 moves forward over the stopper 205, the second return spring 207 will pull the stopper 205 back to the initial state under the elastic force. Therefore, the first arm 208 not only plays the role of installing the second return spring 207, but also plays the role of blocking the stopper 205 from rotating, and the blocking of the stopper 205 is more reliable.

[0065] like Figure 4 , Figure 5 and Figure 7 As shown, the stopper 205 has a stopper surface 213 close to the first arm 208. Correspondingly, the second guide surface 206 is a surface away from the first arm 208. When the limiting member 101 moves in the negative direction and contacts the stopper 205, it will contact the stopper surface 213. At this time, the stopper 205 has a tendency to rotate in the first direction, but at this time the stopper surface 213 will abut against the first arm 208, and then the first arm 208 prevents the stopper 205 from rotating in the first direction. At this time, the negative movement of the seat 1 is blocked by the stop mechanism 2.

[0066] like Figure 4 , Figure 5 and Figure 7 As shown, when the limiting member 101 moves forward and contacts the stopper 205, the limiting member 101 contacts the second guide surface 206, thereby pushing the stopper 205 to rotate in the second direction, and at this time, the portion of the stopper surface 213 opposite to the first arm 208 is away from the first arm 208, thereby allowing the stopper 205 to rotate in the second direction. At this time, the forward movement of the seat 1 is not blocked.

[0067] like Figure 4, Figure 5 and Figure 7 As shown, when the stop member 205 rotates to a certain angle along the second direction, a portion of the stop surface 213 that is not opposite to the first arm 208 in the initial state abuts against the first arm 208, thereby preventing the stop member 205 from rotating further and preventing the stop member 205 from rotating too much and failing to return to the initial state.

[0068] like Figures 2 to 6 As shown, the stop mechanism 2 in the two embodiments can be installed on the vehicle body floor or on the slide rail assembly 3, and the layout space is more flexible.

[0069] Specifically, the stop mechanism 2 is suitable for being installed on the vehicle body floor to meet the space layout requirements. Alternatively, the stop mechanism 2 is suitable for being installed on the second slide rail 302 of the slide rail assembly 3, and the second slide rail 302 is suitable for being installed on the vehicle body floor. The advantage of this structure is that since the seat 1 slides positively or negatively through the first slide rail 301, and the first slide rail 301 and the second slide rail 302 are slidably matched, the stop mechanism 2 is installed on the second slide rail 302, so that the stop position of the stop mechanism 2 for the seat 1 can be adjusted more conveniently.

[0070] like Figure 1 and Figure 7 As shown, the seat 1 can be at a second tilt angle α. When the seat 1 is at the second tilt angle α, the positive movement and negative movement of the seat 1 are not blocked by the stop mechanism 2 .

[0071] Specifically, Figure 1 As shown, when the ground lock 5 locks the seat 1, the seat 1 is at a second tilt angle α, which can refer to the angle between the seat surface L2 and the horizontal plane L1, or the angle between the seat back and the horizontal plane. Fig.10 As shown, at this time, the floor lock 5 remains in the locked state, the seat 1 is at the second tilt angle α, the lowest point of the limiter 101 is always higher than the highest point of the stop mechanism 2, and the two will not contact each other. Therefore, the positive movement of the seat 1 is not blocked by the stop mechanism 2. Similarly, the negative movement of the seat 1 is not blocked by the stop mechanism 2. α can be zero degrees or other angles, and β is not equal to α. Figure 1 and Fig.10 As shown, the seat 1 is provided with a limit member 101, and when the seat 1 is in the second tilt angle α state, the limit member 101 can not contact the stop mechanism 2. When the seat 1 is in the second tilt angle α state, the limit member 101 is in a higher position, so during the positive and negative movement of the seat 1, the limit member 101 will not contact the stop mechanism 2.

[0072] like Figure 1 ,and Fig.10As shown, the floor lock 5 can lock the seat 1 at the second tilt angle α. Figures 7 to 9 As shown, the floor lock 5 can release the lock of the seat 1 so that the seat 1 can be at the first tilt angle β.

[0073] like Figure 1 , Figures 4 to 10 As shown, taking the rotary stop mechanism 2 as an example, the movement process of the seat 1 is as follows:

[0074] In such Figure 1 In the initial state shown, when a person enters or exits the vehicle, the seat backrest needs to be tilted down, the ground lock 5 releases the lock on the seat 1, the rear part of the seat is raised, and the tilt angle of the seat 1 is changed from the second tilt angle α to the tilt angle α shown in FIG. Figure 7 The first inclination angle β is shown.

[0075] like Figure 7 As shown, with the forward movement of the seat 1 , the limiting member 101 will abut against the second guide surface 206 of the stop member 205 , thereby driving the stop member 205 to rotate along the second direction, allowing the limiting member 101 to pass.

[0076] like Figure 8 As shown, after the limiting member 101 passes through the stopper 205, the stopper 205 returns to the initial state under the pull of the second return spring 207. The seat 1 reaches the end of the forward travel, and people can get on and off the seat conveniently.

[0077] like Fig. 9 As shown, if the seat 1 is maintained at the first inclination angle β, the limit member 101 will contact the stop member 205 again during the negative movement of the seat 1. At this time, since the stop member 205 cannot rotate along the first direction, or can only rotate a very small angle along the first direction, the stop surface 213 does not allow the limit member 101 to pass through the stop member 205 in the negative direction, and the negative movement of the seat 1 is blocked.

[0078] like Fig.10 As shown, only when the seat 1 is restored to the state of the second tilt angle α, the limiting member 101 is lifted upward without being blocked by the stop member 205, and the seat 1 can continue to move negatively and restore to the state as shown in FIG. Figure 1 The position shown in the figure, therefore, the negative movement of the seat 1 will not hit the body of the rear passenger. The ground lock 5 can restore the locking of the seat 1.

[0079] The embodiment of the present application also provides a vehicle, the vehicle comprising a seat blocking mechanism as described in any one of the above items. Therefore, the vehicle can be more convenient for people to enter and exit and prevent people from being injured by being hit, and the convenience and safety of vehicle use are improved.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application.
