Therefore, they should not be construed as limitations on the embodiments of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0051] In the description of the embodiments of this utility model, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model according to the specific circumstances.

[0052] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0053] It should be noted that, for ease of description, when a vehicle seat is in normal use, the front side of the passenger's body is called the front side, and the opposite side is called the rear side; the upper and lower sides of the passenger's body are used to distinguish between up and down, and the left and right sides of the passenger's body are used to distinguish between left and right.

[0054] like Figure 1 As shown, a vehicle seat according to the present invention includes a main body 110, a flip assembly 120, and a ground lock structure 160 as described below.

[0055] Specifically, the flip assembly 120 is located at the rear of the main body 110 and is used to connect to the vehicle body 200. The flip assembly 120 includes a flip shaft 121, which extends in the left-right direction and is fixedly connected to the main body 110. Rotation of the flip shaft 121 can cause the main body 110 to flip back and forth. When the vehicle seat needs to be stored, the flip shaft 121 causes the main body 110 to flip backward. When the vehicle seat needs to be unfolded, the flip shaft 121 causes the main body 110 to flip forward. The ground lock structure 160 is located at the front of the flip assembly 120. The fixing seat 163 of the ground lock structure 160 is connected to the main body 110, the lock body 162 of the ground lock structure 160 is connected to the fixing seat 163, and the latch 161 of the ground lock structure 160 is connected to the vehicle body 200. When the main body 110 is unfolded, the lock body 162 and the latch 161 can be connected and locked to fix the main body 110.

[0056] like Figure 1 and Figure 12 As shown in the figure, a ground lock structure 160 of this utility model is used in a vehicle. The ground lock structure 160 includes a latch 161, a fixing seat 163 and a lock body 162.

[0057] Specifically, the latch 161 is used to connect to the vehicle body 200. The latch 161 is connected to the floor inside the vehicle body 200 and can be fixed to the vehicle body 200 with fasteners such as screws. The fixing seat 163 is used to connect to the main body 110 of the vehicle seat. The fixing seat 163 can be connected to the seat cushion frame 113 of the main body 110 with fasteners such as bolts (the part where the seat cushion frame 113 connects to the fixing seat 163 is not shown in the figure for easy observation). The seat cushion frame 113 can be a frame structure formed by welding multiple metal tubes. When the vehicle seat is unfolded, the fixing seat 163 is located above the latch 161. The lock body 162 has a first end and a second end. The first end is connected to the fixing seat 163, and the second end has a lock hole 1623 for connecting to the latch 161 so that the lock body 162 and the latch 161 are locked together. For example, as Figure 12 and Figure 13 As shown, the latch 161 includes a base plate and a U-shaped locking rod. The base plate is connected to the vehicle body 200, and both ends of the locking rod are connected to the base plate. The second end of the lock body 162 has a groove and a rotating block. The rotating block can rotate to move away from or towards the groove, and the rotating block and the groove can surround each other to form a lock hole 1623. When the rotating block approaches the groove and blocks the opening of the groove, the rotating block and the groove form a through hole, and the locking rod is located in the through hole, locking the latch 161 and the lock body 162. When the rotating block moves away from the opening of the groove, the locking rod can leave the groove, and locking the latch 161 and the lock body 162 are unlocked. The structure and action of locking and unlocking the lock body 162 and the latch 161 can be implemented by existing technology. For example, in Figure 4 In the example, the lock structure 160 also includes an unlocking cable 1691 and a lock motor 169. The unlocking cable 1691 is connected to a rotating block on the lock body 162 and to the lock motor 169. The lock motor 169 drives the unlocking cable 1691, thereby causing the rotating block to rotate, which in turn locks or unlocks the lock body 162 with the latch 161. The first end of the lock body 162 is connected to the fixed base 163, and the lock body 162 can rotate relative to the fixed base 163 between a first position and a second position. For example, in some embodiments, the lock body 162 and the fixed base 163 can be connected by a motor. The motor is connected to the fixed base 163, and the output shaft of the motor is connected to the lock body 162, driving the lock body 162 to rotate between the first position and the second position.

[0058] When the lock body 162 is in the first position, the second end is away from the main body 110, and the latch 161 can connect with the lock hole 1623, so that the lock body 162 and the latch 161 are locked together. After the main body 110 of the vehicle seat is unfolded, the lock body 162 is in the first position, and the latch 161 connects with the lock hole 1623, so that the seat cushion portion of the main body 110 can be fixed to the floor of the vehicle body for passenger seating. Figure 12 and Figure 13As shown in the figure, the lock body 162 is located in the first position, with its first end facing upwards and connected to the fixing seat 163, and its second end facing downwards. The lock body 162 flips upwards from the first position to move towards the second position. When the lock body 162 is in the first position, its second end protrudes from the main body 110 of the vehicle seat, so that when the main body 110 is unfolded, the lock hole can engage with the latch. It is understood that the front side of the seat cushion of the main body 110 is usually higher than the rear side. By rotatably connecting the lock body 162 to the fixing seat 163, the lock body 162 can rotate between the first and second positions to engage with the latch 161, or be stored inside the main body 110. This avoids the problem of the front side of the seat cushion being too thick due to the lock body 162 being directly and completely placed inside the main body 110, thus reducing the space occupied by the main body 110.

[0059] When the lock body 162 is in the second position, its second end is close to the main body 110, and the lock hole 1623 is separated from the latch 161. When the lock body 162 rotates from the first position to the second position, its second end moves upward and gradually approaches the main body 110, so that the entire lock body 162 is as close to the main body 110 as possible, reducing the length of the lock body 162 protruding from the main body 110 and preventing collisions between the lock body 162 and passengers or other objects. In some embodiments, when the main body 110 is unfolded, the first and second ends of the lock body 162 in the second position are at the same height. When the lock body 162 is in the second position, both the lock body 162 and the fixing seat 163 can be located within the main body 110, thereby preventing the lock body 162 from protruding from the main body 110 after the main body 110 is flipped, further preventing collisions between the lock body 162 and passengers or other objects. For example, the fixed seat 163 is connected to the seat frame 113 inside the main body 110, and the bottom of the main body 110 is provided with an opening that connects its interior and exterior. When the lock body 162 rotates between the first position and the second position, it can pass through the opening at the bottom of the main body 110.

[0060] According to the ground lock structure 160 of this utility model embodiment, the first end of the lock body 162 is connected to the fixed base 163, and the lock body 162 can rotate relative to the fixed base 163 between a first position and a second position. When the lock body 162 is in the first position, the second end of the lock body 162 is away from the main body 110, and the lock hole 1623 can be connected to the latch 161. When the lock body 162 is in the second position, the second end of the lock body 162 is close to the main body 110, and the lock hole 1623 is separated from the latch 161, so that the lock body 162 is as close to the main body 110 as possible, reducing the length of the lock body 162 protruding from the main body 110. Therefore, after the vehicle seat is folded and flipped, the lock body 162 is prevented from colliding with passengers or other objects, improving safety.

[0061] like Figure 1 and Figure 2As shown, according to some embodiments of the present invention, the vehicle seat further includes a moving component 150 and a following component 130. The moving component 150 is fixedly connected to the main body 110, and the flipping shaft 121 is connected to the moving component 150. Specifically, the moving component 150 is provided with a first guide rail 1511, which extends in the front-rear direction. The flipping shaft 121 is connected to the first guide rail 1511, and the flipping component 120 can move along the first guide rail 1511 to allow the moving component 150 to move relative to the flipping component 120 in the front-rear direction. The following component 130 is spaced apart from the flipping component 120 in the left-right direction and is connected to the vehicle body 200. The following component 130 includes a second connecting bracket 131 and a sliding member 133. The second connecting bracket 131 is connected to the main body 110, and the second connecting bracket 131 is provided with the second guide rail 1311. The sliding member 133 is rotatably connected to the vehicle body 200 and has a second rotating shaft, which is coaxial with the first rotating shaft. The second guide rail 1311 extends in the front-to-back direction. The slider 133 is connected to and can move along the second guide rail 1311, allowing the second guide rail 1311 to move relative to the slider 133 in the front-to-back direction. The main body 110 includes a seat cushion and a backrest, wherein the moving assembly 150 and the second connecting bracket 131 are both connected to the seat cushion frame 113. The left and right sides of the main body 110 are supported by the flipping assembly 120 and the follower assembly 130. Furthermore, by rotating the moving assembly 150 around a first pivot and the slider 133 around a second pivot, the main body 110 is flipped in the front-to-back direction, allowing it to be stowed or unfolded. The flipping assembly 120 and the follower assembly 130 are both located at the rear end of the main body 110.

[0062] exist Figure 1 In the example, the main body 110 includes a four-part side seat 112 and a six-part side seat 111 that are separated from each other. The four-part side seat 112 and the six-part side seat 111 each include a seat cushion and a backrest. The four-part side seat 112 is in a flipped-down storage state, with both the seat cushion and the backrest of the four-part side seat 112 flipped to the rear side of the first pivot. The six-part side seat 111 is in an unfolded state, with the seat cushion of the six-part side seat 111 located in front of the first pivot, and can be used by passengers.

[0063] The flipping axis 121 of the flipping assembly 120 can move along the first guide rail 1511, and the sliding member 133 can move along the second guide rail 1311. Both the moving assembly 150 and the sliding member 133 are connected to the vehicle body, allowing both the moving assembly 150 and the second connecting bracket 131 to move relative to the vehicle body 200 in the front-rear direction, thereby moving the main body 110 in the front-rear direction. Furthermore, since the first guide rail 1511 is located on the moving assembly 150 connected to the main body 110, and the second guide rail 1311 is located on the second connecting bracket 131 connected to the main body 110, when the main body 110 flips forward or backward, both the first guide rail 1511 and the second guide rail 1311 flip along with the main body 110. Therefore, after adjusting the position of the main body 110 before flipping it for storage, the main body 110 can be flipped directly without needing to move it to the initial position or another designated position before flipping, saving steps and making operation more convenient for the user.

[0064] like Figure 6 and Figure 7 As shown, according to some embodiments of the present invention, the flipping assembly 120 further includes a mounting bracket 123, which is connected to the vehicle body 200. For example, the mounting bracket 123 can be fixedly mounted on the vehicle body 200 by screws or other fasteners. The flipping shaft 121 is rotatably connected to the mounting bracket 123 and can rotate relative to the mounting bracket 123. The flipping assembly 120 also includes a flipping motor 124, which is mounted on the mounting bracket 123. The output shaft of the flipping motor 124 is drively connected to the flipping shaft 121, and the flipping motor 124 can drive the flipping shaft 121 to rotate. The output shaft of the flipping motor 124 and the flipping shaft 121 can be connected by a gear set.

[0065] The moving assembly 150 also includes a first drive assembly 152, a first connecting bracket 151 connected to the main body 110, and a tilting shaft 121 movably connected to the first connecting bracket 151. A tilting motor 124 drives the tilting shaft 121 to rotate, which in turn drives the first connecting bracket 151 to rotate, thereby causing the second connecting bracket 131 of the follower assembly 130 to rotate relative to the vehicle body 200, thus tilting the main body 110. The first drive assembly 152 is located on the first connecting bracket 151 and connected to the tilting shaft 121, and can drive the tilting shaft 121 and the first connecting bracket 151 to move relative to each other in the front-rear direction.

[0066] like Figures 7 to 9As shown, according to some embodiments of the present invention, the first guide rail 1511 is provided with a groove, and the bottom of the groove is provided with a first guide groove 1514 extending in the front-rear direction. The flipping shaft 121 includes a shaft body 1211, a connecting block 1212 and a first fixing member 1213. The shaft body 1211 is connected to the flipping motor 124, and the connecting block 1212 is connected to one end of the shaft body 1211. The connecting block 1212 and the shaft body 1211 can be welded or integrally formed. The connecting block 1212 is disposed within the groove of the first guide rail 1511. The first fixing member 1213 passes through the first guide groove 1514 from the outside of the bottom of the groove and connects to the connecting block 1212, thereby connecting the flipping shaft 121 to the first guide rail 1511 and enabling it to move along the first guide rail 1511. The first fixing member 1213 can be a stepped nut. A washer 1214 can be connected to the connecting block 1212, located between the connecting block 1212 and the bottom of the groove to reduce friction on the connecting block 1212. The shape of the connecting block 1212 can be adapted to the shape of the groove to prevent the connecting block 1212 from rotating relative to the first guide rail 1511. For example, in… Figure 8 In the example, the groove is cuboid in shape, and the connecting block 1212 can be a cuboid that fits the groove. When the shaft 1211 rotates, at least the upper and lower sides of the connecting block 1212 abut against the inner wall of the groove to prevent the connecting block 1212 from rotating in the groove, so that the rotating shaft 121 can drive the first connecting bracket 151 to rotate through the connecting block 1212.

[0067] like Figure 6 As shown, in some embodiments, the first connecting bracket 151 further includes a first connecting member 1512 and a second connecting member 1513. The first connecting member 1512 is connected to one end of the first guide rail 1511, and the second connecting member 1513 is connected to the other end of the first guide rail 1511.

Specifically, the first lead screw 153 is disposed in the groove of the first guide rail 1511, and the first lead screw 153 is connected to a connecting block 1212 of the flip shaft 121. The rotation of the first lead screw 153 drives the connecting block 1212 to move along the first guide rail 1511. The connecting block 1212 can be a nut. In some embodiments, the first lead screw 153 can be directly connected to a motor, and the motor drives the first lead screw 153 to rotate, so that the connecting block 1212 moves relative to the first guide rail 1511, thereby driving the main body 110 to move in the front-back direction.

[0069] like Figure 10 As shown, according to some embodiments of the present invention, the follower assembly 130 further includes a second drive assembly 132. The slider 133 is connected to the second connecting bracket 131 and is movable along the second connecting bracket 131.

For example, the third connecting member 1312 can be connected to the rear side of the seat cushion frame 113, and the fourth connecting member 1313 can be connected to the side of the seat cushion frame 113 extending in the front-back direction. The third connecting member 1312 and the fourth connecting member 1313 can both be U-shaped plate structures to wrap the tubular parts of the seat cushion frame 113 from multiple directions, making the connection more stable.

[0071] like Figure 1 and Figure 14As shown, according to some embodiments of the present invention, the vehicle seat further includes a synchronous shaft 170 and a drive motor 171. The drive motor 171 is connected to the synchronous shaft 170, and the synchronous shaft 170 is respectively connected to the moving component 150 and the second connecting bracket 131. The drive motor 171 and the synchronous shaft 170 can synchronously drive the moving component 150 and the second connecting bracket 131 to move back and forth. Specifically, the drive motor 171 is fixedly connected to the main body 110, one end of the synchronous shaft 170 is connected to the first drive component 152, and the other end is connected to the second drive component 132. The first drive component 152 further includes a first driving gear 155 and a first driven gear 156 that mesh with each other. The first driving gear 155 is connected to the synchronous shaft 170, and the first driven gear 156 is connected to the first lead screw 153, wherein the first driving gear 155 and the first driven gear 156 are disposed in the first gear box 154. The second drive assembly 132 also includes a second driving gear 1323 and a second driven gear that mesh with each other. The second driving gear 1323 is connected to the synchronous shaft 170, and the second driven gear is connected to the second lead screw 1321. The second driving gear 1323 and the second driven gear are located in the second gear box 1322. The drive motor 171 drives the synchronous shaft 170 to rotate, and the synchronous shaft 170 drives the first driving gear 155 and the second driving gear 1323 to rotate, which in turn drives the first lead screw 153 and the second lead screw 1321 to rotate. The first lead screw 153 drives the flip shaft 121 to move back and forth relative to the first connecting bracket 151, and the second lead screw 1321 drives the sliding member 133 to move back and forth relative to the second connecting bracket 131. Thus, the main body 110 moves back and forth relative to the vehicle body through the first connecting bracket 151 and the second connecting bracket 131.

[0072] like Figure 14 and Figure 15 As shown, according to some embodiments of the present invention, the follower assembly 130 further includes a mounting base 136 and a first reset member 137. The mounting base 136 is used to connect with the vehicle body 200. A follower shaft 134 is provided on the sliding member 133, passing through the mounting base 136 and capable of rotating relative to the mounting base 136. The first reset member 137 is connected to the follower shaft 134 and can drive the follower shaft 134 to rotate and reset relative to the mounting base 136. When the vehicle seat needs to be folded and stored, the folding motor 124 on the folding assembly 120 drives the moving assembly 150 to rotate relative to the folding assembly 120, which can drive the second connecting bracket 131 to rotate, that is, drive the sliding member 133 to rotate relative to the mounting base 136. When the vehicle seat needs to be unfolded, the first reset member 137 can provide a certain force to drive the follower shaft 134 to rotate and reset relative to the mounting base 136.

[0073] like Figure 16As shown, the first reset member 137 can be a torsion spring assembly, including a first torsion spring 1371 and a second torsion spring 1372. The follower assembly 130 also includes a fixed frame 138, a dial 139, and a bushing 1341. The fixed frame 138 is connected to the mounting base 136, and a mounting space is formed on the fixed frame 138. The dial 139 is disposed in the mounting space and can rotate relative to the fixed frame 138. The first torsion spring 1371 and the second torsion spring 1372 are disposed on the dial 139, and the torsion arms of the first torsion spring 1371 and the second torsion spring 1372 abut against both the fixed frame 138 and the dial 139. The follower shaft 134 passes through the fixed frame 138 and the dial 139, and the follower shaft 134 can drive the dial 139 to rotate relative to the fixed frame 138. Thus, during the process of reversing and folding the vehicle seat, the second connecting bracket 131 drives the sliding member 133 and the follower rotating shaft 134 to rotate relative to the mounting base 136, causing the dial 139 to rotate relative to the fixed frame 138, thereby compressing the first torsion spring 1371 and the second torsion spring 1372; when the vehicle seat is unfolded, the first torsion spring 1371 and the second torsion spring 1372 can provide force to drive the dial 139 to rotate and reset relative to the fixed frame 138, thereby driving the second connecting bracket 131 to rotate and reset relative to the mounting base 136.

[0074] like Figure 2 and Figure 3 As shown, according to some embodiments of the present invention, the main body 110 includes a four-quarter side seat 112 and a six-quarter side seat 111. Correspondingly, the portion of the seat cushion frame 113 located on the four-quarter side seat 112 is the four-quarter side frame 115, and the portion of the seat cushion frame 113 located on the six-quarter side seat 111 is the six-quarter side frame 114. There are at least two flipping components 120, including a first flipping component 1201 and a second flipping component 1202.

There are at least two follower components 130, including a first follower component 1301 and a second follower component 1302. The first follower component 1301 is connected to the six-point side seat 111 and is located near the four-point side seat 112. The second follower component 1302 is connected to the four-point side seat 112 and is located near the six-point side seat 111. Specifically, the first flipping component 1201 is connected to the six-point side frame 114 and is located at the end away from the four-point side frame 115; the second flipping component 1202 is connected to the four-point side frame 115 and is located at the end away from the six-point side frame 114; both the first follower component 1301 and the second follower component 1302 are located between the six-point side frame 114 and the four-point side frame 115.

[0075] like Figure 10 and Figure 11As shown, according to some embodiments of the present invention, the vehicle seat further includes a central support 140, which is used to connect to the vehicle body 200 and is disposed between the four-quarter side seat body 112 and the six-quarter side seat body 111. The first follower component 1301 and the second follower component 1302 are both rotatably connected to the central support 140. In some embodiments, the central support 140 is provided with a connecting hole. One of the first follower component 1301 and the second follower component 1302 is provided with a connecting sleeve 1332, and the other is provided with a connecting shaft 1331. The connecting shaft 1331 passes through the connecting hole, and the connecting sleeve 1332 is sleeved on the connecting shaft 1331, thereby simplifying the connection structure between the follower component 130 and the vehicle body 200 and facilitating installation. Specifically, the intermediate support 140 includes a connecting plate 141 and a connecting protrusion 143. The connecting plate 141 is used to connect with the vehicle body 200. A flap 142 is also connected to one side of the connecting plate 141. The flap 142 and the connecting plate 141 are not on the same plane, and they form a certain angle between them to connect with different surfaces inside the vehicle body 200, thereby improving the connection strength of the intermediate support 140. The connecting protrusion 143 is provided on the connecting plate 141 and protrudes upward from the connecting plate 141. A connecting hole is provided at the end of the connecting protrusion 143 away from the connecting plate 141, and a lubricating sleeve can be provided in the connecting hole. The first follower component 1301 is located on one side of the connecting protrusion 143, and the sliding member 133 of the first follower component 1301 is provided with a connecting shaft 1331. The second follower component 1302 is located on the other side of the connecting protrusion 143, and the sliding member 133 of the second follower component 1302 is provided with a connecting sleeve 1332. The connecting shaft 1331 passes through the connecting hole to the side where the second follower component 1302 is located, and the connecting sleeve 1332 is sleeved on the connecting shaft 1331.

[0076] like Figure 12 As shown, according to some embodiments of the present invention, the floor lock structure 160 further includes a sliding pivot 164, which is fixedly connected to a fixed base 163. The lock body 162 is sleeved on the sliding pivot 164 and can rotate relative to the sliding pivot 164. Specifically, there can be two fixed bases 163, which are respectively fixedly connected to both ends of the sliding pivot 164 to improve the stability of the sliding pivot 164. In some embodiments, the lock body 162 includes a body 1621, a lock hole 1623 is provided on the body 1621, a bushing 1622 is provided on the body 1621, and the sliding pivot 164 passes through the bushing 1622. Figure 12 As shown, the top of the body 1621 is provided with a cylindrical bushing 1622, and the sliding shaft 164 passes through the bushing 1622 to improve the connection strength between the body 1621 and the sliding shaft 164.

[0077] According to some embodiments of this utility model, the lock body 162 further includes a rotating seat 165 and a guide plate 166. The guide plate 166 is provided with a limiting groove 1661 extending in the front-rear direction. The main body 1621 is provided with a guide member 1624, which is disposed in the limiting groove 1661 and can slide along the limiting groove 1661. The guide member 1624 can be a stepped nut. The main body 1621 is located on one side of the guide plate 166, and the guide member 1624 passes through the limiting groove 1661 from the other side of the guide plate 166 and is connected to the main body 1621. When the main body 110 moves back and forth, the main body 110 drives the fixing seat 163 and the guide plate 166 to move relative to the main body 1621 of the lock body 162 in the front-rear direction. The guide member 1624 moves along the limiting groove 1661 to limit and guide the relative movement of the main body 110 and the main body 1621. Furthermore, when the main body 110 moves back and forth, the sliding shaft 164 can slide relative to the bushing 1622 in the back-and-forth direction. The rotating seat 165 is fixedly connected to the guide plate 166. The rotating seat 165 is sleeved on the sliding shaft 164 and can rotate relative to the sliding shaft 164. When the lock body 162 rotates between the first position and the second position, both the bushing 1622 and the rotating seat 165 rotate around the sliding shaft 164. Figure 12 and Figure 13 As shown, the fixed seat 163 is provided with an installation groove, and the rotating seat 165 is disposed in the installation groove. In the front-back direction, the rotating seat 165 abuts against the fixed seat 163, thereby limiting the relative position of the rotating seat 165 and the sliding shaft 164 in the front-back direction.

[0078] like Figure 4 As shown, according to some embodiments of the present invention, the floor lock structure 160 further includes a leg-retracting cable device 167. The first pull cable 1671 of the leg-retracting cable device 167 is connected to the lock body 162. The leg-retracting cable device 167 can tension the first pull cable 1671 to drive the lock body 162 to move from a first position to a second position. In some embodiments, there are at least two floor lock motors 169. The unlocking cable device 1691 is connected to one of the floor lock motors 169, and the leg-retracting cable device 167 can be connected to the other floor lock motor 169. The floor lock motor 169 can retract the first pull cable 1671 of the leg-retracting cable device 167 to tension, or release and loosen the first pull cable 1671.

[0079] like Figure 5 and Figure 7As shown, according to some embodiments of the present invention, the flipping assembly 120 further includes a winding wheel 122, which is sleeved on the flipping shaft 121, and the flipping shaft 121 is rotatable relative to the winding wheel 122. The floor lock structure 160 also includes a leg-retracting cable device 167, the first cable 1671 of which is connected to the lock body 162, and the second cable 1672 of which is connected to the winding wheel 122. When the flipping shaft 121 rotates relative to the winding wheel 122, the second cable 1672 can be wound around the winding wheel 122 or unwound from the winding wheel 122. Specifically, when the main body 110 flips backward, the flipping shaft 121 rotates backward relative to the winding wheel 122, causing the second pull cable 1672 to wind onto the winding wheel 122, thereby tensioning the first pull cable 1671. The first pull cable 1671 drives the lock body 162 to rotate to the second position. When the main body 110 flips forward, the flipping shaft 121 rotates forward relative to the winding wheel 122, and part of the first pull cable 1671 is unwound from the winding wheel 122, causing the first pull cable 1671 to loosen, and the lock body 162 can rotate to the first position.

[0080] like Figure 7 As shown, the take-up reel 122 is fixedly mounted on the mounting bracket 123, and the tilting shaft 121 passes through the take-up reel 122 and is rotatably connected to the mounting bracket 123. A U-shaped groove is provided on the peripheral wall of the take-up reel 122, and one end of the second pull wire 1672 is connected to the peripheral wall of the take-up reel 122. When the tilting shaft 121 rotates relative to the take-up reel 122, the second pull wire 1672 can be wound around the take-up reel 122 along the U-shaped groove. Figure 5 As shown, in some embodiments, the flipping assembly 120 further includes a pulley 125, which is connected to the mounting bracket 123 and is rotatable. The pulley 125 is located on the side of the take-up reel 122 and in front of it. The second pull cable 1672 is wound around the pulley 125 from the rear and then connected to the take-up reel 122. The pulley 125 provides support for the second pull cable 1672 and can change its direction. Figure 4 and Figure 8As shown, the movable component 150 is provided with a hanging part 157, which is located behind the take-up reel 122. A second pull cable 1672 passes through the hanging part 157 and extends forward to wrap around the pulley 125, finally connecting to the take-up reel 122. When the main body 110 moves forward, it drives the movable component 150 forward, causing the hanging part 157 to approach the pulley 125, slacks the second pull cable 1672, and thus prevents the first pull cable 1671 from exerting tension on the lock body 162. When it is necessary to fold and flip the main body 110, the main body 110 is moved backward until the second pull cable 1672 is tensioned, so that when the main body 110 flips backward, the second pull cable 1672 can be wound around the take-up reel 122. In some embodiments, a retaining sleeve can be provided on the pulley 125 to limit the second pull cable 1672 and prevent it from detaching from the pulley 125.

[0081] like Figure 4 and Figure 13 As shown, according to some embodiments of this utility model, the floor lock structure 160 further includes a support block 168, which is connected to the main body 110. The support block 168 has a wire groove, through which the first pull wire 1671 passes to support and change its direction. The lock body 162 has a pull post 1651, and the first pull wire 1671 is connected to the pull post 1651. Figure 13 In the example, the ground lock structure 160 includes two rotating seats 165, which are respectively located at both ends of the sliding shaft 164. The rotating seat 165 at the front end is provided with a pull wire post 1651, and the support block 168 is located close to the rotating seat 165 provided with the pull wire post 1651.

[0082] like Figure 13 As shown, in some embodiments, the floor lock structure 160 further includes a second reset member 1641, which is connected to the lock body 162 and can drive the lock body 162 to move toward a first position. Specifically, the second reset member 1641 can be a torsion spring, which is sleeved on the sliding pivot 164 and located between the fixed seat 163 and the rotating seat 165. The two torsion arms of the torsion spring abut against the fixed seat 163 and the rotating seat 165, respectively. When the lock body 162 is unlocked from the latch 161, the first pull cable 1671 of the leg retractor 167 is tensioned to pull the lock body 162 to rotate toward the second position, and the second reset member 1641 is twisted. When the main body 110 of the vehicle seat is unfolded and the lock body 162 needs to be locked with the latch 161, the first pull cable 1671 of the leg retractor 167 is released and relaxed, and the lock body 162 rotates toward the first position under the drive of the second reset member 1641.

[0083] According to this utility model, a vehicle includes a body 200 and a vehicle seat as described above. The flip assembly 120 and the latch 161 of the ground lock structure 160 are both connected to the body 200. When the main body 110 of the vehicle seat is unfolded, the lock body 162 is in a first position, and the lock body 162 and the latch 161 can be locked to fix the main body 110. When the vehicle seat needs to be folded and flipped for storage, the lock body 162 and the latch 161 are unlocked, the flip assembly 120 drives the main body 110 to flip backward, the lock body 162 separates from the latch 161, and under the drive of the leg retractor cable 167, the lock body 162 rotates to a second position until the lock body 162 is stored inside the main body 110, thereby preventing the lock body 162 from colliding with the passenger after the vehicle seat is stored, and improving safety.

[0084] The working process of the vehicle seat of this utility model is as follows:

[0085] When the main body 110 is unfolded, the lock body 162 is in the first position and locked with the latch 161, allowing passengers to sit in the vehicle seat. When the position of the main body 110 needs to be adjusted forward or backward, the drive motor 171 drives the synchronous shaft 170 to rotate. The synchronous shaft 170 simultaneously drives the first drive assembly 152 on the moving assembly 150 and the second drive assembly 132 on the follower assembly 130. At the first drive assembly 152, the synchronous shaft 170 drives the first drive gear 155 to rotate. The first drive gear 155 drives the first lead screw 153 to rotate through the first driven gear 156. The rotation of the first lead screw 153 drives the tilting shaft 121 to move along the first lead screw 153, thereby driving the tilting shaft 121 to move along the first guide rail 1511. At the second drive assembly 132, the synchronous shaft 170 drives the second drive gear 1323 to rotate. The second drive gear 1323 drives the second lead screw 1321 to rotate via the second driven gear. The rotation of the second lead screw 1321 causes the sliding member 133 to move along the second lead screw 1321, thereby causing the sliding member 133 to move along the second guide rail 1311. This causes the moving assembly 150 and the second connecting bracket 131 to move in the front-rear direction, thereby causing the main body 110 to move back and forth. When the main body 110 moves back and forth, it causes the fixed seat 163 to move back and forth, causing the guide plate 166 and the sliding shaft 164 to move back and forth relative to the main body 1621 of the lock body 162. When the main body 110 moves back and forth, the ground lock structure 160 can keep the main body 110 connected to the vehicle body and provide support for the main body 110.

[0086] When the vehicle seat needs to be folded up and stored, the lock body 162 unlocks and separates from the latch 161. The folding motor 124 drives the folding shaft 121 to rotate, which in turn drives the first connecting bracket 151 to rotate backward, thereby causing the main body 110 to rotate backward. When the main body 110 rotates backward, the second connecting bracket 131 of the follower assembly 130 rotates with the main body 110; and the folding shaft 121 drives the winding wheel 122 to rotate, causing the second pull cable 1672 of the leg retractor 167 to wind onto the winding wheel 122, thus tensioning the first pull cable 1671 and pulling the lock body 162 to rotate to the second position until the lock body 162 is stored inside the main body 110, preventing the lock body 162 from bumping into passengers or items inside the vehicle and improving safety. It is understood that when the vehicle seat is folded up and stored, the seat cushion and backrest of the main body 110 should be folded for storage.

[0087] In summary, this utility model embodiment provides a floor lock structure, which is connected to a fixed base via a lock body. The lock body can rotate relative to the fixed base between a first position and a second position. When the lock body is in the first position, the lock hole is away from the main body and can connect with the latch; when the lock body is in the second position, the lock hole is separated from the latch and the lock body is located inside the main body. Therefore, after the vehicle seat is folded and flipped, the lock body can be stored inside the main body of the vehicle seat, preventing the lock body from colliding with passengers or other objects and improving safety.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit it. It should be pointed out that those skilled in the art can make several improvements and substitutions without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
