Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and particularly relates to a rear seat and an automobile. Background Art

[0002] With the development of society, people now travel longer distances and carry more luggage, and there are higher requirements for the trunk space of automobiles. However, due to the model limitations of automobiles, higher requirements are put forward for the storage space of the trunk of MPV automobiles. It is necessary to store not only some vehicle tools but also the accompanying items of business personnel. It is difficult to meet the requirements of the automobile storage space only by flipping the seat. Summary of the Invention

[0003] The main object of the present invention is to propose a rear seat, aiming to increase the storage space of the automobile.

[0004] To achieve the above object, the rear seat proposed by the present invention includes:

[0005] A seat body;

[0006] A sliding mechanism, including an upper sliding rail and a lower sliding rail. The lower sliding rail is used to be fixed in the vehicle cabin of the automobile. The upper sliding rail is slidably installed on the lower sliding rail. The seat body is installed on the upper sliding rail, and a flipping mechanism is provided between the end of the upper sliding rail and the seat body; and

[0007] A flipping limiting mechanism, which is arranged between the seat body and the lower sliding rail and is located at one end far from the flipping mechanism;

[0008] Wherein, the seat body has a first position and a second position. In the first position, the seat body is locked by the flipping limiting mechanism. In the second position, the seat body can be flipped relative to the upper sliding rail through the flipping mechanism, and the seat body can slide reciprocally between the first position and the second position.

[0009] Optionally, the flipping limiting mechanism includes a first limiting member rotatably installed on the seat body and a second limiting member arranged on the upper sliding rail;

[0010] In the first position, the first limiting member and the second limiting member are slidably buckled; in the second position, the first limiting member and the second limiting member are disengaged.

[0011] Optionally, a first hook is provided on one side of the first limiting member away from the seat body, and the second hook is provided on one side of the second limiting member close to the first limiting member;

[0012] At the first position, the first hook and the second hook are slidably hooked; at the second position, the first hook and the second hook are disengaged, and the first hook is located on the side of the second hook close to the flipping mechanism.

[0013] Optionally, the first hook and / or the second hook has a guiding surface, and the guiding surface is inclined downward from top to bottom along the direction away from the lower sliding rail.

[0014] Optionally, a limiting bracket is provided between the first limiting member and the seat body. One end of the limiting bracket is fixed to the seat body, and the first limiting member is rotatably mounted at the other end of the limiting bracket.

[0015] Optionally, an elastic member is provided between the first limiting member and the limiting bracket, and the elastic member makes the first hook tend to approach the second hook.

[0016] Optionally, the first limiting member is rotatably connected to the limiting bracket through a rotating shaft, and one end of the first limiting member close to the rotating shaft has a blocking portion;

[0017] When the flipping limiting mechanism is locked, the blocking portion abuts against the limiting bracket, so that there is a gap between the first hook and the second hook.

[0018] Optionally, a ground lock is provided between the seat body and the upper sliding rail for locking the seat body to the upper sliding rail.

[0019] Optionally, the ground lock includes a hook provided on the seat body and a lock catch provided on the upper sliding rail, and the hook is hooked to the lock catch.

[0020] Optionally, a sliding limiting mechanism is provided between the upper sliding rail and the lower sliding rail to limit the relative sliding between the upper sliding rail and the lower sliding rail. The sliding limiting mechanism has a limiting state and an open state that are switched with each other. In the limiting state, the sliding limiting mechanism restricts the sliding of the upper sliding rail.

[0021] The present invention also provides an automobile, including a passenger compartment and the rear seat as described above, and the rear seat is provided on the chassis in the passenger compartment.

[0022] The technical solution of the present invention is to provide a sliding mechanism and a flipping limiting mechanism inside the passenger compartment of a vehicle. The sliding mechanism includes an upper sliding rail and a lower sliding rail. The lower sliding rail is used to be fixed inside the passenger compartment of the vehicle, and the upper sliding rail is slidably installed on the lower sliding rail. The seat body is installed on the upper sliding rail, and a flipping mechanism is provided between the end of the upper sliding rail and the seat body. The flipping limiting mechanism is arranged between the seat body and the lower sliding rail and is located at one end away from the flipping mechanism. This enables the upper sliding rail to drive the seat body to slide relative to the lower sliding rail, causing the seat body to reciprocally slide between a first position and a second position. Among them, the seat body has a first position locked by the flipping limiting mechanism and a second position where it can flip relative to the upper sliding rail. When the seat body is in the first position, the flipping limiting mechanism is locked, so that the seat body is locked on the upper sliding rail and cannot flip relative to the upper sliding rail, but can only slide relative to the lower sliding rail together with the upper sliding rail. When the seat body is in the second position, the flipping limiting mechanism is opened, so that the seat body can both flip relative to the upper sliding rail and slide relative to the lower sliding rail together with the upper sliding rail. When the storage space in the vehicle trunk required by the user is insufficient, the user can make the seat body slide forward a certain distance before flipping forward, so that the entire seat body moves forward to increase the storage space in the trunk at the back of the vehicle, and then flip it to further increase the storage space in the trunk at the back of the vehicle, thereby effectively increasing the internal storage space of the vehicle and meeting the user's needs. And because during the sliding process of the seat body, since the flipping limiting mechanism is in a locked state, the seat body will not flip during the forward movement, thus improving the stability of the seat body when sliding forward.

[0037] The present invention proposes a rear seat.

[0038] In the embodiments of the present invention, asFigures 1 to 3 As shown, the rear seat includes a seat body 100, a sliding mechanism 110, and a flipping limit mechanism 130. The sliding mechanism 110 includes an upper sliding rail 111 and a lower sliding rail 112. The lower sliding rail 112 is used to be fixed in the vehicle cabin of the automobile. The upper sliding rail 111 is slidably installed on the lower sliding rail 112. The seat body 100 is installed on the upper sliding rail 111, and a flipping mechanism 120 is provided between the end of the upper sliding rail 111 and the seat body 100. The flipping limit mechanism 130 is arranged between the seat body 100 and the lower sliding rail 112 and is located at one end away from the flipping mechanism 120. Among them, the seat body 100 has a first position and a second position. In the first position, the seat body 100 is locked by the flipping limit mechanism 130. In the second position, the seat body 100 can be flipped relative to the upper sliding rail 11 by the flipping mechanism 120, and the seat body 100 can reciprocally slide between the first position and the second position.

[0039] Specifically, the lower slide rail 112 is fixed inside the car cabin of the vehicle, and the seat body 100 is installed on the upper slide rail 111, such that the upper slide rail 111 drives the seat body 100 to slide relative to the lower slide rail 112. The seat body 100 is installed on the upper slide rail 112, and the flipping mechanism 120 is disposed on the side away from the backrest of the seat body 100, that is, on the side close to the front row seat, and the flipping limit mechanism 130 is disposed on the side close to the backrest of the seat body 100, that is, on the side close to the trunk of the vehicle. In this embodiment, the flipping mechanism 120 is a rotating hinge 121 connected between the seat body 100 and the upper slide rail 111. Moreover, the rotation angle between the seat body 100 and the upper slide rail 111 is not limited by the structure of the rotating hinge 121, and is only related to the internal structure of the vehicle. When the seat body 100 is in the first position, the flipping limit mechanism 130 is locked, such that the seat body 100 is locked on the upper slide rail 111 and cannot flip relative to the upper slide rail 111, and can only slide relative to the lower slide rail 112 together with the upper slide rail 111. When the seat body 100 is in the second position, the flipping limit mechanism 130 is opened, such that the seat body 100 can both flip relative to the upper slide rail 111 and slide relative to the lower slide rail 112 together with the upper slide rail 111. When the seat body 100 is between the first position and the second position, the flipping limit mechanism 130 is also in the locked state, and the first position can be used as the initial position of the seat body 100, but the second position is not the termination position of the seat body 100, that is, when the seat body 100 slides to the second position, the flipping limit mechanism 130 is opened, and the seat body 100 can flip forward, but the seat body 100 can still continue to slide forward a certain distance. By making the seat body 100 slide forward a certain distance before flipping forward, the overall front movement of the seat body 100 is achieved, thereby increasing the storage space of the trunk behind the vehicle, and then flipping is performed to further increase the storage space of the trunk behind the vehicle. Moreover, because the flipping limit mechanism 130 is in the locked state when the seat body 100 slides between the first position and the second position, the seat body 100 will not flip during the forward movement process, thereby improving the stability of the seat body 100 when sliding forward. In addition, regulations stipulate that the width of the rear row seat must be greater than 1200 mm. However, due to the model limitations of some vehicles, such as MPV vehicles, interference may occur between the rear wheel arch of the vehicle and the rear row seat in the width direction of the vehicle, making it difficult for the rear row seat to directly flip. If forced to flip, it may cause damage to the surface of the rear row seat, thereby affecting the service life of the rear row seat. In this solution, the seat can be moved forward first to avoid the rear wheel arch, and then flipped, thereby avoiding the interference of the rear wheel arch on the flipping of the rear row seat, ensuring the smooth flipping of the seat body 100, and further improving the service life of the rear row seat.

[0040] Movement process of the seat body 100: When the user needs to expand the storage space of the car trunk, first make the upper slide rail 111 drive the seat body 100 to move forward to the second position to increase the storage space of the car trunk. Then, the seat body 100 is flipped forward through the flipping mechanism 120 for the passengers to place the items to be stored. When the seat body 100 is reset, it can first slide the seat body 100 backward. After it is in the first position, flip the seat body 100 backward and lock it with the flipping limit mechanism 130. It can also first flip the seat body 100 backward and then slide the seat body 100 backward to the first position and lock it with the flipping limit mechanism 130. Or it can first slide the seat body 100 backward for a certain distance and then flip the seat body 100 backward. After the flipping is completed, continue to slide backward to the first position. That is, the reset sequence of the sliding and flipping of the seat body 100 is not restricted. In this embodiment, the passengers manually slide and flip the seat body 100 and perform the reset of the seat body 100. Of course, in other embodiments, relevant control modules and drive modules can also be set to realize the automatic forward movement, flipping and reset of the seat body 100.

[0041] In the technical solution of the present invention, the seat body 100 is installed on the upper slide rail 111 through the sliding mechanism 110 and the flipping limit mechanism 130. The upper slide rail 111 drives the seat body 100 to slide relative to the lower slide rail 112, so that the seat body 100 reciprocates between the first position and the second position. In the first position, that is, the position where the seat body 100 is located when the car is driving, the seat body 100 is locked on the upper slide rail 111 and cannot flip relative to the upper slide rail 111, but can only slide relative to the lower slide rail 112 together with the upper slide rail 111. In the second position, that is, the position where the flipping limit mechanism 130 is opened, the seat body 100 can both flip relative to the upper slide rail 111 and slide relative to the lower slide rail 112 together with the upper slide rail 111. When the storage space of the car trunk required by the user is insufficient, the user can make the seat body 100 slide forward for a certain distance before flipping forward, so that the whole seat body 100 moves forward to increase the storage space of the car trunk at the back, and then flip it to further increase the storage space of the car trunk at the back, thereby effectively increasing the internal storage space of the car and meeting the user's needs. And when the seat body 100 slides between the first position and the second position, since the flipping limit mechanism 130 is in the locked state, the seat body 100 will not flip during the forward movement, thus improving the stability of the seat body 100 when sliding forward.

[0042] In one embodiment, the flipping limit mechanism 130 includes a first limiting member 131 rotatably installed on the seat body 100 and a second limiting member 132 provided on the upper slide rail 111;

[0043] At the first position, the first limiting member 131 is slidably buckled with the second limiting member 132; at the second position, the first limiting member 131 is disengaged from the second limiting member 132. Specifically, when the flipping limiting mechanism 130 is locked, the first limiting member 131 is slidably buckled with the second limiting member 132, so that the first limiting member 131 can only slide along the second limiting member 132 and cannot be disengaged from the second limiting member 132. When the seat body 100 is at the first position, the first limiting member 131 is located at one end of the second limiting member 132 close to the trunk of the vehicle, and the first limiting member 131 and the second limiting member 132 are at least partially buckled; when the seat body 100 is at the second position, the first limiting member 131 is located at one end of the second limiting member 132 close to the front row seat, and the first limiting member 131 and the second limiting member 132 are exactly completely disengaged, so that when the seat body 100 is between the first position and the second position, the flipping limiting mechanism 130 is in a locked state, and the flipping limiting mechanism 130 can be opened only when the seat body 100 is at the second position, that is, the first limiting member 131 is disengaged from the second limiting member 132. At this time, the seat body 100 can be flipped relative to the sliding mechanism 110, thereby ensuring the locking stability of the flipping limiting mechanism 130. However, it should be noted that the location of the second position is not the end position of the movement of the seat body 100, and the seat body 100 can still slide forward for a certain distance. Both the first limiting member 131 and the second limiting member 132 have a certain width. In this embodiment, the width of the first limiting member 131 is greater than the width of the second limiting member 132. In other embodiments, the width of the first limiting member 131 may also be less than or equal to the width of the second limiting member 132.

[0044] Further, a first hook 133 is provided on a side of the first limiting member 131 away from the seat body 100, and a second hook 134 is provided on a side of the second limiting member 132 close to the first limiting member 131;

[0045] At the first position, the first hook 133 and the second hook 134 are slidably hooked; at the second position, the first hook 133 and the second hook 134 are disengaged, and the first hook 133 is located on the side of the second hook 134 close to the flipping mechanism 120. Specifically, at the first position, the flipping limit mechanism 130 is locked by hooking the first hook 133 and the second hook 134. By pushing the seat body 100, the first hook 133 slides relative to the second hook 134. When reaching the second position, the first hook 133 disengages from the second hook 134. In this embodiment, the reset of the seat body 100 adopts the form of sliding first and then flipping. When it is necessary to lock the seat body 100 again, only need to first slide the seat body 100 to the first position, and then flip the seat body 100 backward. At this time, the first limiting member 131 drives the first hook 133 to rotate a preset angle in a direction away from the second hook 134, and at the same time, the first hook 133 is driven by the seat body 100 to move downward, so that the first hook 133 moves to the lower side of the second hook 134 along with the seat body 100. Then the first limiting member 131 drives the first hook 133 to rotate in the reverse direction, so that the first hook 133 is hooked to the second hook 134 again, thereby locking the limiting flipping mechanism 120 again. Of course, in other embodiments, the reset of the seat body 100 can also adopt the form of flipping first and then sliding. At this time, because it is necessary for the first hook 133 and the second hook 134 to be hooked again, but because the first limiting member 131 can rotate within a small range, during the sliding process, it is difficult to ensure the alignment of the first hook 133 and the second hook 134, and thus it is difficult to ensure that the first hook 133 is hooked to the second hook 134 again, affecting the smoothness of the reset of the seat body 100.

[0046] In another embodiment, a clamping protrusion is provided on the side of the first limiting member 131 away from the seat body 100, and a clamping groove is provided on the second limiting member 132. The first opening of the clamping groove faces away from the lower guide rail, and the clamping groove extends along the moving direction of the seat body 100, and the clamping groove has a second opening facing the second position;

[0047] At the first position, the clamping protrusion is inserted into the clamping groove, thereby locking the flipping limit mechanism 130; at the second position, the clamping protrusion disengages from the clamping groove from the second opening.

[0048] If the form of the clamping groove and the clamping protrusion is used for locking, when the seat body 100 is reset, it is necessary to first flip the seat body 100 backward, and then slide the seat body 100 backward, so that the clamping protrusion is inserted into the clamping groove again from the second opening, thereby locking the flipping limit mechanism 130. However, such a setting is not conducive to the stability of the seat body 100 during reset, and has a greater impact on whether the clamping protrusion can be inserted into the clamping groove, and it is difficult to ensure the re-locking of the flipping limit mechanism 130.

[0049] When the reset mode of the seat body 100 is to slide backward first and then flip backward, in order to further guide the rotation of the first hook 133, in one embodiment, refer to Figure 3 , the first hook 133 and / or the second hook 134 is provided with a guiding surface 135, and the guiding surface 135 is inclined from top to bottom along the direction away from the lower slide rail 112. Specifically, the first hook 133 and / or the second hook 134 is provided with a guiding surface 135, that is, the guiding surface 135 can be provided on the first hook 133 or on the second hook 134; or are respectively provided on the first hook 133 and the second hook 134 and are located on the opposite sides of the first hook 133 and the second hook 134. The following will take the example that the guiding surfaces 135 are provided on both the first hook 133 and the second hook 134 for illustration. When the flipping limiting mechanism 130 needs to be locked, the seat body 100 drives the first limiting member 131 to move downward due to its own weight until the guiding surface 135 of the first hook 133 contacts the guiding surface 135 of the second hook 134, and the guiding surface 135 is inclined from top to bottom along the direction away from the lower slide rail 112, so that the guiding surface 135 pushes the first limiting member 131 to rotate relative to the seat body 100, causing the first hook 133 to move away from the second hook 134 and gradually fall as the seat body 100 flips backward, so that the first hook 133 moves to the lower part of the second hook 134, and then the first limiting member 131 rotates again in the direction close to the second hook 134, so that the first hook 133 and the second hook 134 are hooked together, thereby locking the flipping limiting mechanism 130.

[0050] Furthermore, an elastic member 137 is provided between the first limiting member 131 and the limiting bracket 136, and the elastic member 137 makes the first hook 133 tend to approach the second hook 134. Specifically, when the first hook 133 moves to the lower part of the second hook 134, in order to ensure that the first hook 133 can automatically rotate in the direction close to the second hook 134 so as to be hooked and locked with the second hook 134. Therefore, an elastic member 137 is provided between the first limiting member 131 and the limiting bracket 136, making the first hook 133 tend to approach the second hook 134. Thus, it is convenient to lock the flipping limiting mechanism 130. And because the gravitational potential energy of the seat is greater than the elastic potential energy of the elastic member 137, the first limiting member 131 can fall to the lower part of the second hook 134 along with the flipping of the seat body 100 without getting stuck during the backward flipping process of the seat body 100.

[0051] In this embodiment, the first limiting member 131 is rotatably connected to the limiting bracket 136 through a rotating shaft 138. The elastic member 137 is a torsion spring. The torsion spring is sleeved on the rotating shaft 138, and the opposite sides of the torsion spring respectively abut against the two opposite sides of the limiting bracket 136 and the first limiting member 131. Moreover, the structure of the torsion spring is simple and the installation is convenient. Of course, in other embodiments, the elastic member 137 can also be a compression spring, and the compression spring is arranged on one side of the rotating shaft 138 close to the first hook 133; or the elastic member 137 is a tension spring, and the tension spring is arranged on one side of the rotating shaft 138 away from the first hook 133.

[0052] In one embodiment, referring to Figure 3 , a limiting bracket 136 is provided between the first limiting member 131 and the seat body 100. One end of the limiting bracket 136 is fixed to the seat body 100, and the first limiting member 131 is rotatably installed at the other end of the limiting bracket 136. Specifically, the first limiting member 131 is rotatably installed on the seat body 100 through the limiting bracket 136, so as to facilitate adjusting the installation position of the first limiting member 131 and facilitate the assembly of the first limiting member 131.

[0053] In one embodiment, the first limiting member 131 is rotatably connected to the limiting bracket 136 through a rotating shaft 138, and one end of the first limiting member 131 close to the rotating shaft 138 has a blocking portion 139;

[0054] When the flipping limiting mechanism 130 is locked, the blocking portion 139 abuts against the limiting bracket 136, so that there is a gap between the first hook 133 and the second hook 134. Specifically, the blocking portion 139 is formed by a flange on one side of the end of the first limiting member 131 close to the rotating shaft 138 facing the limiting bracket 136. When the flipping limiting mechanism 130 is locked, the blocking portion 139 abuts against the limiting bracket 136, thereby restricting the deflection angle of the first limiting member 131 towards the second limiting member 132, and further restricting the distance between the first hook 133 and the second hook 134. So that there can be a certain gap while ensuring the engagement between the first hook 133 and the second hook 134. Since the first hook 133 needs to slide relative to the second hook 134, if they come into contact with each other, there will be a large frictional force, which not only easily wears the first hook 133 and the second hook 134, reducing the service life of the flipping limiting mechanism 130, but also generates a large noise during the sliding process of the seat body 100, increasing the force required for the user to push the seat body 100, thus affecting the user experience.

[0055] Refer to again Figure 3 and Figure 4, a floor lock 140 is provided between the seat body 100 and the upper slide rail 111. Specifically, the floor lock 140 is used to further lock the seat body 100 on the upper slide rail 111. When the floor lock 140 is not opened, the seat body 100 cannot be flipped regardless of whether the flip limiting mechanism 130 is in the locked state or the opened state; only when the floor lock 140 is in the opened state and the seat body 100 is in the second position, can the seat body 100 be flipped. When it is necessary to expand the storage space of the car trunk, the floor lock 140 needs to be opened first, and then the seat body 100 can be slid forward to the second position. After the seat body 100 is reset, the floor lock 140 is locked again, thereby further strengthening the flip limiting mechanism 120, improving the installation stability of the seat body 100 and the sliding mechanism 110, and reducing the possibility of the flip limiting mechanism 130 being accidentally opened.

[0056] Furthermore, the floor lock 140 includes a lock hook 141 provided on the seat body 100 and a lock catch 142 provided on the upper slide rail 111, and the lock hook 141 is hooked to the lock catch 142. Among them, the lock hook 141 of the floor lock 140 has a lock groove with an opening on one side. When the floor lock 140 is in the locked state, the opening direction of the lock groove is arranged at an angle with the lock catch 142, thereby restricting the flipping of the seat body 100. Rotate the lock hook 141 so that the opening direction of the lock groove faces the lock catch 142, thereby opening the floor lock 140. And in this embodiment, the lock hook 141 is integrally semicircular, thereby reducing the rotation space required for the lock hook 141.

[0057] In one embodiment, a sliding limiting mechanism 150 is provided between the upper slide rail 111 and the lower slide rail 112. The sliding limiting mechanism 150 has a limiting state and an opened state that can be switched to each other. In the limiting state, the sliding limiting mechanism 150 restricts the sliding of the upper slide rail. Specifically, in the limiting state, the sliding limiting mechanism 150 can lock the upper slide rail 111 and the lower slide rail 112 so that the two are fixed to each other. Thereby reducing the possibility of the seat body 100 sliding accidentally during the normal driving of the car.

[0058] Among them, the sliding limiting mechanism 150 is provided between the upper slide rail 111 and the lower slide rail 112, referring to Figure 5 and Figure 6, the sliding limiting mechanism 150 includes a toothed plate 151. The toothed plate 151 is installed between the upper slide rail 111 and the lower slide rail 112, and the toothed plate 151 is provided with locking teeth 152. A through hole 111b is provided on the top wall 111a of the upper slide rail 111, and an internal tooth window 111d is provided on the side wall 111c of the upper slide rail 111. The lower slide rail 112 has an inward flange 112a on the side wall 111c of the upper slide rail 111. An external tooth window 112b is provided on the inward flange 112a, and the external tooth window 112b is open toward the bottom wall 112c of the lower slide rail 112. The width of the internal tooth window 111d is greater than the width of the external tooth window 112b. The toothed plate 151 is elastically installed on the upper slide rail 111 and has a locking pin 153 that passes upward through the through hole 111b in the top wall 111a of the upper slide rail 111. In the limiting state, the locking teeth 152 sequentially pass through the internal tooth window 111d and the external tooth window 112b, thereby restricting the relative sliding of the upper slide rail 111 and the lower slide rail, that is, locking the upper slide rail 111 and the lower slide rail 112. Pressing the locking pin 153 causes the toothed plate 151 to move downward relative to the internal tooth window 111d and the external tooth window 112b, and then to disengage from the opening of the external tooth window 112b, thereby releasing the insertion of the locking teeth 152 and the external tooth window 112b, so that the upper slide rail 111 can move relative to the lower slide rail 112, that is, the sliding limiting mechanism 150 is in the unlocked state. Therefore, when the user needs to slide the seat body 100, the locking pin 153 needs to be continuously pressed. Of course, an unlocking mechanism can also be provided so that the user can press the locking pin 153 through the unlocking mechanism, thereby releasing the locking of the upper slide rail 111 and the lower slide rail 112, facilitating the user to slide the seat body 100.
