[0020] In order to solve the technical problem, the utility model further provides a vehicle, the vehicle comprising a frame and a seat as described in any one of the above items, the base being connected to the frame.

[0021] Compared with the prior art, the seat and vehicle of the present invention have the following advantages:

[0022] 1. The utility model provides a chair, comprising a base, a seat, a pressing piece and a locking piece, wherein the seat and the base are stacked in the Z direction and are slidably connected in the X direction; one end of the pressing piece extends into the seat and is movably connected to the inner wall of the seat, and the other end is exposed on a side of the seat close to the base; the locking piece is arranged in the seat, and the seat is provided with a through hole corresponding to the locking piece; the locking piece is at least partially in contact with the pressing piece, and at least partially can be extended from the through hole in the Y direction; at least two locking grooves are arranged at intervals in the X direction on the wall surface opposite to the through hole, and the extended part of the locking piece is locked in the locking groove; the exposed end of the pressing piece is pressed in the Z direction to drive the extended part of the locking piece to move in the Y direction to disengage from the locking groove. By setting the locking member to at least partially contact with the pressing member, and at least partially extend from the through hole along the Y direction, and the extended part is locked in the locking groove, when the exposed end of the pressing member is pressed along the Z direction, the pressing member can be moved along the Z direction, and the locking member can be driven to move along the Y direction to disengage from the locking groove. Thus, the seat and the base are positioned by locking and unlocking the locking member, and the front-to-back distance between the seat and the handle is adjusted while the locking member is limited from the side. Compared with the existing seat, because the limiting direction of the limiting member is the same as the pressing direction, the limiting structure and the limiting groove cannot be close to each other when locked, and there is space left, which makes the seat easy to shake. By setting the pressing member and the locking member to move in different directions, the locking member can always press against the locking groove when locked, thereby achieving lateral support and preventing the seat from shaking left and right.

[0023] 2. The locking member of the utility model is a rotating member; by pressing the exposed end of the pressing member in the Z direction, the extended part of the rotating member is driven to rotate in the seat in the Y direction to disengage from the lock slot. By setting the rotating member for locking and rotation, the movement of the rotating member can be made more flexible and unlocking can be made easier. In addition, the locking and unlocking of the rotating member is specifically achieved through rotational movement. During the entire rotation process, the axis of rotation of the rotating member remains unchanged, and the overall position space has not changed. The power required for the rotation of the locking member is relatively small. Compared with the existing unlocking method of the seat, since the limiting direction of the limiting member is the same as the pressing direction, a sufficient pressing depth is required when pressing to drive the limiting block to disengage as a whole to achieve unlocking. The rotating member in the seat of the utility model can be rotated by a smaller pressing force and pressing depth, thereby making the press-type unlocking of the seat easier and more convenient.

[0024] 3. The base of the utility model is provided with locking grooves on two opposite sides near one end of the seat, and the number of locking grooves on each side is at least two; two rotating parts are provided on the seat corresponding to the locking grooves, and the two rotating parts are arranged oppositely. By providing two opposite locking grooves and correspondingly providing two rotating parts oppositely, the two rotating parts are symmetrical, and the two rotating parts support the two sides of the pressing part, so that the support is more balanced. In addition, the two sides of the pressing part are limited, so as to achieve the balance of the limit, so that the seat on the base will not be deflected, and the structure is more stable and durable.

[0025] 4. An elastic member is arranged between the seat cover and the pressing member of the utility model, and the elastic member is arranged close to the pressing member exposed from the bottom shell. By arranging the elastic member to be connected with the pressing member, the pressing member can be quickly reset by the rebound of the elastic member after being pressed by the pressing member.

[0026] 5. The rotating end of the utility model is provided with a rotating shaft and a first shaft groove, the connecting part is provided with a positioning shaft, the bottom shell is provided with a receiving groove, the receiving groove is provided with a through hole corresponding to the locking groove, the notch of the receiving groove is provided with a second shaft groove, and the rotating shaft and the positioning shaft are connected with the first shaft groove and the second shaft groove respectively. When the pressing member is pressed along the Z direction, the pressing member moves along the Z direction, that is, when it moves toward the direction close to the seat cover, it will drive the positioning shaft on the pressing member to move in the same direction, thereby driving the rotating shaft of the rotating end to rotate in the second shaft groove, and the rotation of the rotating shaft drives the locking end to rotate out of the locking groove and pass through the through hole into the receiving groove, thereby realizing the locking and unlocking with the base through the rotation of the rotating member, so as to realize the adjustment of the distance between the seat and the front of the vehicle.

[0027] 6. The bottom shell of the utility model is provided with a sliding member on one side close to the base, and a boundary protrusion is provided on the sliding member. A first sliding groove is formed between the boundary protrusion and the bottom shell, and a second sliding groove is provided on the base; the boundary of the base slides in the first sliding groove, and the boundary protrusion slides in the second sliding groove. Thus, the boundary protrusion of the sliding member and the boundary of the base are mutually engaged and slidable, making the sliding connection between the two more stable, thereby making the overall structure more stable.

[0028] 7. The utility model provides a fastener on the side of the connecting part close to the seat cover, and a pressing groove is provided on the side of the fastener close to the connecting part, and part of the rotating end is located in the pressing groove. By providing a fastener on the connecting part to press the rotating end and the connecting part, the situation of the rotating part being separated from the through hole is effectively avoided, the movement of the connecting part is also avoided, and the instability of the overall movement of the pressing part is avoided.

[0029] 8. The bottom shell of the utility model is provided with two limit blocks on one side close to the seat cover. The two limit blocks are arranged opposite to each other, and part of the pressing piece is inserted between the two limit blocks. By providing two limit blocks, the two limit blocks are engaged with the boundaries of the pressing piece, thereby limiting the pressing piece, thereby avoiding the offset and dislocation of the pressing piece on the bottom shell, and making the overall structure of the seat more stable.

[0030] 9. The utility model also provides a vehicle having the same beneficial effects as the above-mentioned seat, which will not be described in detail here.

For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0052] See also Figure 1-Figure 2 The first embodiment of the utility model provides a chair 1, comprising a base 11, a seat 10, a pressing member 14 and a locking member 20, wherein the seat 10 and the base 11 are stacked along the Z direction and are slidably connected along the X direction;

[0053] One end of the pressing member 14 extends into the seat 10 and is movably connected to the inner wall of the seat 10, and the other end is exposed on a side of the seat 10 close to the base 11;

[0054] The locking member 20 is disposed in the seat 10, and a through hole 1212 is formed in the seat 10 corresponding to the locking member 20; the locking member 20 is at least partially in contact with the pressing member 14, and at least partially can extend from the through hole 1212 along the Y direction; at least two locking grooves 111 are arranged at intervals along the X direction on the wall surface of the base 11 opposite to the through hole 1212, and the extended part of the locking member 20 is locked in the locking groove 111;

[0055] The exposed end of the pressing member 14 is pressed along the Z direction, so that the extended portion of the locking member 20 moves along the Y direction and leaves the locking groove 111 .

[0056] Specifically, the base 11 is used to connect with the vehicle frame, so as to realize the connection between the seat 1 and the frame as a whole. Specifically, the connection between the base 11 and the frame can be realized by threaded connection, which is convenient for disassembling and repairing the vehicle. The part of the pressing member 14 that enters the seat 10 is movably connected with the inner wall of the seat 10, so when the pressing member 14 is pressed, the pressed end can move along the Z direction, and after the pressing is completed, it can move in the opposite direction of the Z direction, so as to return to the initial position. When the pressing member 14 is not pressed, at least part of the locking member 20 can extend from the through hole 1212 along the Y direction into the locking groove 111 on the base 11, so as to realize locking. And the size and shape of the locking groove 111 can be matched with the size and shape of the part of the locking member 20 extending from the through hole 1212, so that the part of the locking member 20 extending into the locking groove 111 can be tightly pressed against the groove wall of the locking groove 111.

[0057] It can be understood that the positioning member 20 is at least partially in contact with the pressing member 14, and at least partially can be extended from the through hole 1212 in the Y direction, and the extended part is locked in the locking groove 111 to achieve locking with the base 11; when the exposed end of the pressing member 14 is pressed in the Z direction, the pressing member 14 can be moved in the Z direction, and the positioning member 20 can be driven to move in the Y direction to disengage from the locking groove 111 to achieve unlocking with the base 11. In this way, the lateral positioning limitation and unlocking of the positioning member 20 are achieved. After unlocking, the seat 10 can be pushed, so that the seat 10 and the base 11 can slide in the X direction accordingly, and slide onto the base 11, and the corresponding position of the next locking groove 111 is locked, thereby achieving the positioning of the seat 10 and the base 11 through the locking and unlocking of the positioning member 20, and achieving the front-to-back distance adjustment between the seat 10 and the handle. Compared with the existing seats, since the limiting direction of the limiting member is the same as the pressing direction, a certain space needs to be reserved between the limiting structure and the limiting groove to achieve the locking of the limiting structure into the limiting groove, which results in the limiting structure and the limiting groove being unable to be close to each other during locking, and the space left makes the seat easy to shake. In this embodiment, the pressing member 14 and the locking member 20 are arranged to move in different directions, so that the locking member 20 can always press against the locking groove 111 during locking, thereby achieving lateral support and preventing the seat 10 from shaking left and right.

[0058] See also Figure 3-Figure 5 Further, the locking member 20 is a rotating member 15; the exposed end of the pressing member 14 is pressed along the Z direction, driving the extended portion of the rotating member 15 to rotate along the Y direction into the seat 10 to disengage from the locking groove 111.

[0059] It can be understood that when the locking member 20 is a rotating member 15, the locking and rotation are performed by the rotating member 15, and the rotation method can make the movement of the rotating member 15 more flexible and easier to unlock. In addition, the rotating member 15 is specifically locked and unlocked by rotational movement. During the entire rotation process, the axis of rotation of the rotating member 15 remains unchanged, and the overall position space does not change. The power required for the rotating member to rotate is relatively small. Compared with the unlocking method of the existing seat, since the limiting direction of the limiting member is the same as the pressing direction, a sufficient pressing depth is required when pressing to drive the limiting block to be disengaged as a whole to achieve unlocking. The rotating member 15 in the seat 1 in this embodiment can be rotated by a relatively small pressing force and pressing depth, thereby making the press-type unlocking of the seat 1 easier and more convenient.

[0060] Optionally, the number of the rotating member 15 is at least one, and locking is achieved by one rotating member 15, which is easier to operate. Two, three or four rotating members 15 may also be provided, thereby improving the locking effect by providing multiple rotating members 15.

[0061] See also Figure 3-Figure 7 Furthermore, the seat 10 includes a bottom shell 12 and a seat cover 13, the seat cover 13 covers the bottom shell 12 to form a accommodating space 18, the bottom shell 12 and the base 11 are stacked along the Z direction and are slidably connected along the X direction; a through hole 1212 is opened on the bottom shell 12, one end of the pressing member 14 extends into the accommodating space 18 and is movably connected to the bottom shell 12, and the other end is exposed on the side of the bottom shell 12 close to the base 11; an elastic member 16 is arranged between the seat cover 13 and the pressing member 14, and the elastic member 16 is arranged close to the part of the pressing member 14 exposed from the bottom shell 12.

[0062] Specifically, the seat cover 13 can cover the bottom shell 12 and form a receiving space 18, which can accommodate the rotating member 15 and part of the pressing member 14. The bottom shell 12 is provided with an opening 124 on one side close to the base 11, and the other part of the pressing member 14 that is not accommodated in the receiving space 18 passes through the opening 124 and is exposed on the surface of the bottom shell 12, and the end of the pressing member 14 located in the receiving space 18 and away from the opening 124 is connected to the bottom shell 12 and limited, that is, it is limited in the current position and cannot move. Therefore, the end of the pressing member 14 located in the receiving space 18 and away from the opening 124 is limited, and the part of the pressing member 14 exposed on the surface of the bottom shell 12 can move in the direction close to the seat cover 13 under the action of pressing to enter the receiving space 18, and after the pressing is completed, it moves in the direction away from the seat cover 13 to pass through the opening 124 again and be exposed on the surface of the bottom shell 12.

[0063] More specifically, when the pressing member 14 is in the unpressed state, one end of the rotating member 15 is connected to the pressing member 14, and the other end of the rotating member 15 extends out of the through hole 1212 and is inserted into the locking groove 111 on the base 11, thereby achieving the locking of the rotating member 15 and the base 11, thereby achieving the locking of the base 11 and the base 11 with the whole body composed of the bottom shell 12, the seat cover 13, the pressing member 14 and the rotating member 15. Therefore, when the part of the pressing member 14 exposed on the surface of the bottom shell 12 moves toward the direction close to the seat cover 13 under the action of pressing, that is, moves along the Z direction, the rotating member 15 can be driven to rotate. When the rotating member 15 rotates, the part of the rotating member 15 inserted into the locking groove 111 moves along the Y direction due to the rotation, and is separated from the locking groove 111 and passes through the through hole 1212, thereby completing the unlocking of the rotating member 15 and the base 11. At this time, since the bottom shell 12 is slidably connected with the base 11, the bottom shell 12 and the base 11 can be relatively slid by pushing any part of the bottom shell 12, the seat cover 13 and the pressing member 14, and the partial rotating member 15 that is out of the current locking groove 111 is locked in the next locking groove 111 through the relative sliding of the base and the base 11, thereby adjusting the distance between the seat 1 and the front of the vehicle to meet the different distance requirements of different children for the seat 1 and the front of the vehicle. In addition, by driving the rotating member 15 to rotate and unlock and the bottom shell 12 and the base 11 to slide, the distance between the seat 1 and the front of the vehicle can be adjusted without disassembling the bottom shell 12 and the base 11, which is simpler and more flexible than the existing detachable adjustment. In addition, the movement direction of the pressing member 14 after being pressed in the direction close to the seat cover 13 can be regarded as movement in the Z direction, and the movement of the rotating member 15 to make the end inserted into the lock slot 111 disengage from the lock slot 111 can be regarded as movement in the Y direction. Therefore, the movement direction of the pressing member 14 and the movement direction of the rotating member 15 are two completely different directions. By moving the rotating member 15 in the Y direction, lateral support for the pressing member 14 can be achieved, thereby preventing the seat 10 from shaking as a whole compared to the base 11.

[0064] It should be noted that the connection between one end of the rotating member 15 and the pressing member 14 can be a fixed connection or a movable connection, and this embodiment does not limit this, as long as the movement of the pressing member can drive the rotating member to rotate. In this embodiment, preferably, the movable connection can be a rotating connection, and the use of a rotating connection can make the rotation of the rotating member 15 more flexible.

[0065] It can be understood that an elastic member 16 can also be disposed in the accommodating space 18, and the two ends of the elastic member 16 can be connected to the seat cover 13 and the pressing member 14 respectively, specifically connected to the end of the pressing member 14 near the opening 124 away from the bottom shell 12. When pressing, the pressing member 14 moves toward the seat cover 13, so that the elastic member 16 is compressed. After the pressing stops, the elastic member 16 stretches and rebounds, driving the pressing member 14 to move away from the seat cover 13, so that the pressing member 14 can be quickly reset by the rebound of the elastic member 16.

[0066] Optionally, the elastic member 16 can be a return spring, a hollow column 131 can be provided on the side of the seat cover 13 close to the bottom shell 12, a bracket 143 is provided at the end of the pressing member 14 close to the opening 124 that is away from the bottom shell 12, corresponding to the hollow column 131, one end of the return spring is inserted into the hollow column 131, and the other end is sleeved on the outer surface of the bracket 143, thereby achieving a firm connection between the return spring, the seat cover 13 and the pressing member 14, and making the connection between the return spring, the seat cover 13 and the pressing member 14 more stable. In addition, the bracket 143 abuts against the return spring to avoid deformation of the return spring.

[0067] See also Figure 3 Furthermore, locking grooves 111 are provided on two opposite sides of the base 11 near one end of the seat 10, and the number of the locking grooves 111 on each side is at least two; two rotating members 15 are provided on the seat 1 corresponding to the locking grooves 111, and the two rotating members 15 are arranged opposite to each other.

[0068] Specifically, in this embodiment, the number of rotating members 15 is preferably two, and the two rotating members 15 are arranged opposite to each other and arranged in a direction perpendicular to the sliding direction of the seat 10. Further, the bottom is arranged in a direction perpendicular to the sliding direction of the bottom shell 12, that is, it is arranged on the two long sides of the part of the pressing member 14 located in the accommodating space 18 that are in the same sliding direction as the bottom shell 12. The position of the locking groove 111 on the base 11 is opposite to the position of the rotating member 15, and can be arranged on two opposite sides of the base 11 close to one end of the bottom shell 12. The number of locking grooves 111 on each side needs to be at least two, and all the locking grooves on each side are arranged linearly and spaced apart, so as to achieve the adjustment of the distance between the seat 1 and the front of the vehicle. The number of locking grooves 111 on each side can also be three or more than three, thereby expanding the range of distance adjustment between the seat 1 and the front of the vehicle, making the distance adjustment more flexible and more selective, and meeting the adjustment needs of more users. The locking of the two rotating members 15 and the locking groove 111 in a relative state can make the two rotating members 15 symmetrical, realize the support of the two rotating members 15 on both sides of the pressing member 14, and make the support more balanced. In addition, the symmetrical state of the two rotating members 15 also realizes the limit of both sides of the pressing member 14, thereby achieving the balance of the limit, making the locking effect between the rotating member 15 and the locking groove 111 more stable and balanced, so that the seat 1 on the base 11 will not be deflected, and the structure is more stable and durable.

[0069] See also Figure 3 and Figure 5 Furthermore, the pressing member 14 includes a pressing portion 141 exposed from the bottom shell 12 and a connecting portion 142 connected to the bottom shell 12, and the pressing portion 141 is connected to the elastic member 16 on a side facing away from the bottom shell 12; the rotating member 15 includes a rotating end 151 and a locking end 152, the rotating end 151 is connected to the pressing member 14, and the locking end 152 is inserted into the locking groove 111.

[0070] Specifically, the entirety of the connecting portion 142 is located in the accommodating space 18, and one end of the connecting portion 142 away from the opening 124 is fixed in a limited position. The side of the pressing portion 141 close to the bottom shell 12 protrudes and passes through the surface of the bottom shell 12 for the user to press, and the side of the pressing portion 141 away from the bottom shell 12 is connected to the elastic member 16. The rotating member 15 is connected to the connecting portion 142. When the pressing portion 141 is pressed, the pressing portion 141 moves toward the direction close to the seat cover 13, driving part of the connecting portion 142 to move toward the direction close to the seat cover 13, thereby driving the rotating member 15 to rotate, so that the rotating member 15 is disengaged from the lock slot 111 to achieve unlocking.

[0071] It should be noted that the pressing portion 141 and the connecting portion 142 can be integrally formed, thereby improving the overall structural stability and strength of the pressing member 14 .

[0072] Specifically, the rotating end 151 is connected to the connecting portion 142 of the pressing member 14, and the locking end 152 protrudes relative to the rotating end 151, that is, the locking end 152 extends out of the through hole 1212 and is locked in the locking groove 111 to achieve locking. Therefore, when the pressing portion 141 is pressed, the pressing portion 141 moves in a direction close to the seat cover 13, driving part of the connecting portion 142 to move in a direction close to the seat cover 13, that is, moving along the Z direction, thereby driving the rotating end 151 of the rotating member 15 to rotate on the connecting portion 142, causing the locking end 152 to rotate to move in the Y direction to leave the current position and disengage from the locking groove 111, thereby passing through the through hole 1212 to achieve unlocking.

[0073] It should be noted that the rotating end 151 and the locking end 152 may also be integrally formed, thereby improving the overall structural stability and strength of the rotating member 15 , and further improving the connection strength between the rotating member 15 and the base 11 and the pressing member 14 .

[0074] See also Figure 3 and Figure 5Furthermore, a rotating shaft 1511 and a first shaft groove 1512 are provided on the rotating end 151, a positioning shaft 1421 is provided on the connecting portion 142, a receiving groove 121 is provided on the bottom shell 12, a through hole 1212 is provided on the receiving groove 121 corresponding to the lock groove 111, a second shaft groove 1211 is provided at the notch of the receiving groove 121, the rotating shaft 1511 and the positioning shaft 1421 are respectively connected to the first shaft groove 1512 and the second shaft groove 1211; the positioning shaft 1421 moves, driving the rotating shaft 1511 to rotate in the second shaft groove 1211, and the rotation of the rotating shaft 1511 drives the locking end 152 to rotate out of the lock groove 111 and pass through the through hole 1212 to enter the receiving groove 121.

[0075] Specifically, the connection portion 142 may be provided with a positioning shaft 1421, and the rotating member 15 may be sleeved on the first shaft groove 1512 through the first shaft groove 1512 on the rotating end 151 to achieve connection with the pressing member 14. In this embodiment, the rotating member 15 may also rotate relative to the positioning shaft 1421, so that the connection between the two is more flexible.

[0076] More specifically, a through hole 1212 may be provided on the groove wall of the receiving groove 121 corresponding to the locking end 152 of the rotating member 15 and the locking groove 111, and a second shaft groove 1211 may be provided at the notch of the receiving groove 121. The rotating end 151 of the rotating member 15 is entirely located in the receiving groove 121, and the locking end 152 extends out of the receiving groove 121 from the through hole 1212 and is inserted into the locking groove 111. The receiving groove 121 is in a through state with the locking groove 111 through the through hole 1212, so that the locking end 152 can be rotated to move along the Y direction to disengage from the locking groove 111 and pass through the through hole 1212 to enter the receiving groove 121. The rotating shaft 1511 on the rotating end 151 can be located in the second shaft groove 1211 and can rotate in the second shaft groove 1211, so that the rotating member 15 is supported by the second shaft groove 1211 and the positioning shaft 1421 to prevent the rotating member 15 from falling directly into the receiving groove 121.

[0077] It can be understood that the rotating shaft 1511 and the positioning shaft 1421 are connected to the first shaft groove 1512 and the second shaft groove 1211 respectively, and the connection is specifically a movable connection, preferably a rotating connection, which can make the rotation of the rotating member 15 more flexible. When the pressing member 14 moves in the direction close to the seat cover 13, it will drive the connecting portion 142 on the pressing member 14 to move in the direction close to the seat cover 13, so that the positioning shaft 1421 on the connecting portion 142 also moves in the direction close to the seat cover 13, thereby driving the rotating shaft 1511 of the rotating end 151 to rotate in the second shaft groove 1211, and the rotation of the rotating shaft 1511 drives the locking end 152 to rotate out of the locking groove 111 and pass through the through hole 1212 to enter the receiving groove 121, thereby realizing the locking and unlocking with the base 11 through the rotation of the rotating member 15, so as to achieve the adjustment of the distance between the seat 1 and the front of the vehicle.

[0078] See also Figure 8 and Fig. 9 Furthermore, a sliding member 122 is provided on the side of the bottom shell 12 close to the base 11, and a boundary protrusion 1221 is provided on the sliding member 122. A first sliding groove 1222 is formed between the boundary protrusion 1221 and the bottom shell 12, and a second sliding groove 112 is provided on the base 11; the boundary of the base 11 slides in the first sliding groove 1222, and the boundary protrusion 1221 slides in the second sliding groove 112.

[0079] Specifically, a sliding member 122 fixedly connected to the bottom shell 12 can be provided on the bottom shell 12, and a boundary protrusion 1221 on the sliding member 122 facing away from the bottom shell 12 can form a first sliding groove 1222 with the bottom shell 12. A second sliding groove 112 is provided on the base 11 corresponding to the boundary protrusion 1221, that is, the base 11 is provided with a locking groove 111 and a second sliding groove 112 in sequence from the boundary to the direction away from the bottom shell 12. The boundary of the base 11 can be inserted into the first sliding groove 1222 and slide in the first sliding groove 1222, and the boundary protrusion 1221 can be inserted into the second sliding groove 112 and slide in the second sliding groove 112, so that the boundary protrusion 1221 of the sliding member 122 and the boundary of the base 11 can be mutually engaged and slidable, so that the sliding connection between the two is more stable, thereby making the overall structure more stable. In addition, by providing the first sliding groove 1222 on the separately provided sliding member 122, the influence of the sliding process on other structures of the seat 1 can be effectively avoided.

[0080] It should be noted that when a sliding member 122 is provided at one end of the bottom shell 12 close to the base 11, a limiting groove 1223 is provided on the sliding member 122 corresponding to the position of the receiving groove 121 on the bottom shell 12, and the bottom of the receiving groove 121 passes through the limiting groove 1223, thereby forming a rotation space that can accommodate the entire rotating member 15 and allow rotation. One opposite side of the limiting groove 1223 corresponds to the through-through setting of the two rotating members 15, so that after being combined with the receiving groove 121, a through hole 1212 can be formed for the locking end 152 of the rotating member 15 to extend out. Therefore, the sliding member 122 provided separately not only realizes the sliding connection with the seat 10, but also realizes its locking effect, thereby effectively avoiding the influence of the sliding process and the locking and unlocking process on other structures of the seat 1 through the sliding process and the locking and unlocking process.

[0081] It should be noted that the locking groove 111 and the second sliding groove 112 are in a separated state, so that the locking of the locking groove 111 and the sliding of the second sliding groove 112 are prevented from interfering with each other.

[0082] As another embodiment, a first sliding groove 1222 is provided on one side of the bottom shell 12 close to the base 11, and the boundary of the base 11 is slidably connected to the first sliding groove 1222. By directly providing the first sliding groove 1222 on the bottom shell 12, it is not necessary to separately provide a part connected to the bottom shell 12 to provide a sliding groove, which can make the overall structure of the bottom shell 12 more stable, and is also conducive to improving the connection strength of the sliding connection between the bottom shell 12 and the base 11. In addition, the sliding connection and relative sliding between the bottom shell 12, the pressing member 14, the rotating member 15, and the seat cover 13 as a whole and the base 11 are achieved, and the provision of the first sliding groove 1222 clarifies the sliding direction and sliding distance between the bottom shell 12 and the base 11, avoiding the situation of slipping.

[0083] See also Figure 3 and Figure 4 Further, a fastener 17 is provided on one side of the connection portion 142 close to the seat cover 13 , and a pressing groove 171 is provided on one side of the fastener 17 close to the connection portion 142 , and a portion of the rotating end 151 is located in the pressing groove 171 .

[0084] It can be understood that the fastener 17 can be located at a position corresponding to the connection portion 142 and fixedly connected to the side of the bottom shell 12 close to the seat cover 13. Thus, the fastener 17 presses the connection portion 142 and covers the side of the rotating end 151 close to the seat cover 13. A pressing groove 171 is provided on the fastener 17 corresponding to the rotating end 151 of the rotating member 15, and the pressing groove 171 can cover the side of the rotating end 151 close to the seat cover 13, and there is a certain distance between the rotating end 151 and the pressing groove 171, so that when the fastener 17 covers the rotating end 151, the rotating member 15 can still rotate. Therefore, the setting of the fastener 17 avoids the situation of deviation in the connection on the bottom shell 12, thereby avoiding the situation of instability in the overall movement of the pressing member 14. In addition, it can effectively prevent the rotating member 15 from escaping from the through hole 1212.

[0085] See also Figure 2 Furthermore, two limit blocks 123 are provided on one side of the bottom shell 12 close to the seat cover 13 . The two limit blocks 123 are arranged opposite to each other, and part of the pressing member 14 is inserted between the two limit blocks 123 .

[0086] It can be understood that the two limit blocks 123 are arranged opposite to each other, and the pressing member 14 can pass between the two limit blocks 123, and the two sides of the boundary of part of the pressing member 14 are respectively abutted against the two limit blocks 123, so that the pressing member 14 is limited to the current position by the limit blocks 123. In this way, the pressing member 14 is limited when it is not pressed, so as to avoid the offset and misalignment of the pressing member 14 on the bottom shell 12, making the overall structure of the seat 1 more stable; and after pressing, the limited pressing member 14 can only move in the direction close to the seat cover 13 formed by the limit blocks 123, and cannot shake around in the accommodating space 18, so that the direction of the pressing process is clearer and the pressing is more stable.

[0087] See also Fig.10 The second embodiment of the utility model provides a vehicle 3 , which includes a frame 2 and the seat 1 in the first embodiment, and a base 11 is connected to the frame 2 .

[0088] It can be understood that the base 11 is used to connect with the frame 2 of the vehicle 3, so as to realize the connection between the seat 1 and the frame 2 as a whole. And the connection between the base and the frame 2 is a fixed connection, so the seat 10 as a whole can slide relative to the base 11 and the frame 2, so as to realize the adjustment of the distance between the seat 1 and the front of the vehicle 3. The connection between the base 11 and the frame 2 of the vehicle 3 can be realized by screws or threaded connections. The threaded connection is conducive to the disassembly and maintenance of the vehicle 3. The vehicle in the second embodiment includes the seat in the first embodiment. Therefore, the second embodiment has the same beneficial effects as the above-mentioned seat 1, which will not be repeated here.

[0089] Compared with the prior art, the seat and vehicle of the present invention have the following advantages:

[0090] 1. The utility model provides a chair, comprising a base, a seat, a pressing piece and a locking piece, wherein the seat and the base are stacked in the Z direction and are slidably connected in the X direction; one end of the pressing piece extends into the seat and is movably connected to the inner wall of the seat, and the other end is exposed on a side of the seat close to the base; the locking piece is arranged in the seat, and the seat is provided with a through hole corresponding to the locking piece; the locking piece is at least partially in contact with the pressing piece, and at least partially can be extended from the through hole in the Y direction; at least two locking grooves are arranged at intervals in the X direction on the wall surface opposite to the through hole, and the extended part of the locking piece is locked in the locking groove; the exposed end of the pressing piece is pressed in the Z direction to drive the extended part of the locking piece to move in the Y direction to disengage from the locking groove. By setting the locking member to at least partially contact with the pressing member, and at least partially extend from the through hole along the Y direction, and the extended part is locked in the locking groove, when the exposed end of the pressing member is pressed along the Z direction, the pressing member can be moved along the Z direction, and the locking member can be driven to move along the Y direction to disengage from the locking groove. Thus, the seat and the base are positioned by locking and unlocking the locking member, and the front-to-back distance between the seat and the handle is adjusted while the locking member is limited from the side. Compared with the existing seat, because the limiting direction of the limiting member is the same as the pressing direction, the limiting structure and the limiting groove cannot be close to each other when locked, and there is space left, which makes the seat easy to shake. By setting the pressing member and the locking member to move in different directions, the locking member can always press against the locking groove when locked, thereby achieving lateral support and preventing the seat from shaking left and right.

[0091] 2. The locking member of the utility model is a rotating member; by pressing the exposed end of the pressing member in the Z direction, the extended part of the rotating member is driven to rotate in the seat in the Y direction to disengage from the lock slot. By setting the rotating member for locking and rotation, the movement of the rotating member can be made more flexible and unlocking can be made easier. In addition, the locking and unlocking of the rotating member is specifically achieved through rotational movement. During the entire rotation process, the axis of rotation of the rotating member remains unchanged, and the overall position space has not changed. The power required for the rotation of the locking member is relatively small. Compared with the existing unlocking method of the seat, since the limiting direction of the limiting member is the same as the pressing direction, a sufficient pressing depth is required when pressing to drive the limiting block to disengage as a whole to achieve unlocking. The rotating member in the seat of the utility model can be rotated by a smaller pressing force and pressing depth, thereby making the press-type unlocking of the seat easier and more convenient.

[0092] 3. The base of the utility model is provided with locking grooves on two opposite sides near one end of the seat, and the number of locking grooves on each side is at least two; two rotating parts are provided on the seat corresponding to the locking grooves, and the two rotating parts are arranged oppositely. By providing two opposite locking grooves and correspondingly providing two rotating parts oppositely, the two rotating parts are symmetrical, and the two rotating parts support the two sides of the pressing part, so that the support is more balanced. In addition, the two sides of the pressing part are limited, so as to achieve the balance of the limit, so that the seat on the base will not be deflected, and the structure is more stable and durable.

[0093] 4. An elastic member is arranged between the seat cover and the pressing member of the utility model, and the elastic member is arranged close to the pressing member exposed from the bottom shell. By arranging the elastic member to be connected with the pressing member, the pressing member can be quickly reset by the rebound of the elastic member after being pressed by the pressing member.

[0094] 5. The rotating end of the utility model is provided with a rotating shaft and a first shaft groove, the connecting part is provided with a positioning shaft, the bottom shell is provided with a receiving groove, the receiving groove is provided with a through hole corresponding to the locking groove, the notch of the receiving groove is provided with a second shaft groove, and the rotating shaft and the positioning shaft are connected with the first shaft groove and the second shaft groove respectively. When the pressing member is pressed along the Z direction, the pressing member moves along the Z direction, that is, when it moves toward the direction close to the seat cover, it will drive the positioning shaft on the pressing member to move in the same direction, thereby driving the rotating shaft of the rotating end to rotate in the second shaft groove, and the rotation of the rotating shaft drives the locking end to rotate out of the locking groove and pass through the through hole into the receiving groove, thereby realizing the locking and unlocking with the base through the rotation of the rotating member, so as to realize the adjustment of the distance between the seat and the front of the vehicle.

[0095] 6. The bottom shell of the utility model is provided with a sliding member on one side close to the base, and a boundary protrusion is provided on the sliding member. A first sliding groove is formed between the boundary protrusion and the bottom shell, and a second sliding groove is provided on the base; the boundary of the base slides in the first sliding groove, and the boundary protrusion slides in the second sliding groove. Thus, the boundary protrusion of the sliding member and the boundary of the base are mutually engaged and slidable, making the sliding connection between the two more stable, thereby making the overall structure more stable.

[0096] 7. The utility model provides a fastener on the side of the connecting part close to the seat cover, and a pressing groove is provided on the side of the fastener close to the connecting part, and part of the rotating end is located in the pressing groove. By providing a fastener on the connecting part to press the rotating end and the connecting part, the situation of the rotating part being separated from the through hole is effectively avoided, the movement of the connecting part is also avoided, and the instability of the overall movement of the pressing part is avoided.

[0097] 8. The bottom shell of the utility model is provided with two limit blocks on one side close to the seat cover. The two limit blocks are arranged opposite to each other, and part of the pressing piece is inserted between the two limit blocks. By providing two limit blocks, the two limit blocks are engaged with the boundaries of the pressing piece, thereby limiting the pressing piece, thereby avoiding the offset and dislocation of the pressing piece on the bottom shell, and making the overall structure of the seat more stable.

[0098] 9. The utility model also provides a vehicle having the same beneficial effects as the above-mentioned seat, which will not be described in detail here.

[0099] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included in the protection scope of the present invention.
