[0033] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0034] Most existing child safety seats use a fixed footrest design. While this fixed footrest structure can meet the basic leg support function, the fixed height footrest is difficult to adapt to the natural bending angle of the legs of children of different ages due to the significant changes in leg length during children's growth. When the child's legs are dangling or excessively bent, the comfort of riding is greatly reduced.

[0035] Please refer to Figures 1-5 An embodiment of this application provides a seat, including a seat body 100, a support leg 200, and a footrest 300. The support leg 200 is disposed on the seat body 100. The footrest 300 includes a first fixed seat 310 and a second fixed seat 320. The first fixed seat 310 and the second fixed seat 320 are detachably connected to form a through hole between the first fixed seat 310 and the second fixed seat 320. The support leg 200 passes through the through hole. A first anti-slip member 311 is movably disposed on the first fixed seat 310. A driving member 312 is also disposed on the first fixed seat 310. The driving member 312 is used to drive the first anti-slip member 311 to move toward the second fixed seat 320 so as to hold the support leg 200 tightly between the first anti-slip member 311 and the second fixed seat 320.

[0036] The first fixing seat 310 and the second fixing seat 320 are detachably connected so that the foot pedal 300 can be removed from the support leg 200. When the first fixing seat 310 and the second fixing seat 320 are connected as one unit, a through hole is formed between the first fixing seat 310 and the second fixing seat 320, and the support leg 200 passes through the through hole. One of the first fixing seat 310 and the second fixing seat 320 is a load-bearing component, on which a panel 380 for passengers to step on is provided.

[0037] The first fixed base 310 may be provided with a sliding groove that slides with the first anti-slip member 311, so that the first anti-slip member 311 can move relative to the first fixed base 310. The direction of movement of the first anti-slip member 311 is towards or away from the second fixed base 320. The driving member 312 can drive the first anti-slip member 311 to move towards the second fixed base 320 until the first anti-slip member 311 abuts against the second fixed base 320. At this time, the first anti-slip member 311 and the second fixed base 320 together hold the support leg 200, thereby fixing the foot pedal 300 relative to the support leg 200.

[0038] When the height of the foot pedal 300 needs to be adjusted, the drive component 312 is reversed, and the first anti-slip component 311 can move away from the second fixed seat 320 until it is disengaged from the support leg 200. At this time, the height of the foot pedal 300 can be adjusted up and down. When the height of the foot pedal 300 is adjusted to the correct position, the drive component 312 is used to drive the first anti-slip component 311 to move toward the second fixed seat 320 until the first anti-slip component 311 is pressed against the second fixed seat 320, thereby fixing the foot pedal 300 relative to the support leg 200 again.

[0039] In some embodiments, the driving member 312 includes a driving part 3121 and a wedge block 3122. The wedge block 3122 is movably disposed on the first fixed base 310. The first anti-slip member 311 is provided with an inclined surface that cooperates with the wedge block 3122. The driving part 3121 is used to drive the wedge block 3122 to move, thereby pushing the first anti-slip member 311 toward the second fixed base 320 through the inclined surface.

[0040] The wedge block 3122 itself has an inclined surface, and the first anti-slip member 311 is provided with another inclined surface that cooperates with the inclined surface of the wedge block 3122. During the process of the drive unit 3121 driving the wedge block 3122 to move, the inclined surface of the wedge block 3122 moves relative to the inclined surface of the first anti-slip member 311, thereby pushing the first anti-slip member 311 to move toward the second fixed seat 320. The moving direction of the wedge block 3122 is the height direction of the support leg 200.

[0041] In this embodiment, the moving direction of the wedge block 3122 is perpendicular to the moving direction of the first anti-slip member 311. It is understood that in other embodiments, the angle between the moving direction of the wedge block 3122 and the moving direction of the first anti-slip member 311 can be greater than or less than 90°, as long as the moving wedge block 3122 can drive the first anti-slip member 311 to move synchronously.

[0042] To ensure the stability of the movement of the wedge block 3122 and the first anti-slip member 311, the first fixed base 310 is provided with track cavities for the wedge block 3122 and the first anti-slip member 311 to slide respectively.

[0043] Optionally, the drive unit 3121 is a knob, which is rotatably mounted on the first fixed base 310. The knob is provided with a stud, which is threadedly engaged with the wedge block 3122.

[0044] A fixing plate 313 is fixedly installed on the first fixing base 310, and the knob is rotatably connected to the fixing plate 313. Alternatively, the fixing plate 313 is rotatably installed on the first fixing base 310, and the knob is fixedly connected to the fixing plate 313. Both methods enable the knob to rotate relative to the first fixing base 310.

[0045] When the height of the foot pedal 300 is adjusted to the correct position, turn the knob. The knob will cause the stud to rotate, and the stud will cause the wedge block 3122 to move along the height direction of the support leg 200. This will push the first anti-slip member 311 toward the second fixed seat 320 until the first anti-slip member 311 is pressed against the support leg 200. At this time, the foot pedal 300 and the support leg 200 are relatively fixed.

[0046] In other embodiments, please refer to Figure 6 The driving component 312 is a bolt 3123, which is threadedly engaged with the first fixed seat 310, and the bolt 3123 is used to abut against and push the first anti-slip component 311 toward the second fixed seat 320.

[0047] When the height of the foot pedal 300 is adjusted to the correct position, rotate the bolt 3123. The bolt 3123 abuts against and pushes the first anti-slip member 311 toward the second fixed seat 320 until the first anti-slip member 311 is pressed against the support leg 200. At this time, the foot pedal 300 and the support leg 200 are relatively fixed.

[0048] Because the bolt 3123 is threadedly engaged with the first fixed seat 310, the bolt 3123 is not prone to retraction, thereby enabling the first anti-slip component 311 to be stably pressed against the support leg 200, thus ensuring the stability of the foot pedal 300.

[0049] In some embodiments, please refer to Figure 7 , Figure 8 The first anti-slip member 311 includes a first anti-slip plate 3111 and a connecting block 3112 connected together. A first elastic member 3113 and a first stop pin 3114 are provided between the first anti-slip plate 3111 and the connecting block 3112. The first stop pin 3114 can pass through the first anti-slip plate 3111 under the action of the first elastic member 3113 so as to cooperate with the stop hole 210 on the support leg 200.

[0050] The first anti-slip plate 3111 is closer to the support leg 200 than the connecting block 3112. The first anti-slip plate 3111 has a hole through which the first stop pin 3114 passes. For the support leg 200 with stop holes 210, the support leg 200 has multiple stop holes 210 spaced apart along its own height direction. When the first stop pin 3114 passes through the first anti-slip plate 3111, it can cooperate with any stop hole 210 on the support leg 200.

[0051] Taking the driving component 312 as a bolt 3123 as an example, the bolt 3123 can abut against and push the connecting block 3112 to move during the rotation process, thereby causing the first anti-slip plate 3111 to move toward the second fixed seat 320 until the first anti-slip plate 3111 abuts against the support leg 200. At this time, the first anti-slip plate 3111 can also cooperate with the second fixed seat 320 to hold the support leg 200 together.

[0052] When the foot pedal 300 is installed on the support leg 200 with the shift hole 210, the first anti-slip plate 3111 and the second fixing seat 320 can jointly hold the support leg 200 tightly. At the same time, the first shift pin 3114 can pass through the first anti-slip plate 3111 under the action of the first elastic member 3113 and lock into either shift hole 210, achieving double locking. When the foot pedal 300 is installed on the support leg 200 without the shift hole 210, the foot pedal 300 can also be fixed by the first anti-slip plate 3111 and the second fixing seat 320 jointly holding the support leg 200. At this time, the first shift pin 3114 is retracted by the action of the support leg 200, and the first elastic member 3113 is in a compressed state.

[0053] The pedal 300 equipped with the aforementioned first anti-slip element 311 can be used with both the support leg 200 with the shift hole 210 and the support leg 200 without the shift hole 210, thus improving the adaptability of the pedal 300.

[0054] In some embodiments, a second elastic member 314 is provided between the first anti-slip member 311 and the first fixed base 310. The second elastic member 314 is used to make the first anti-slip member 311 always have a tendency to move away from the second fixed base 320.

[0055] To enable rapid height adjustment of the foot pedal 300, a second elastic element 314 is provided between the first anti-slip element 311 and the first fixed seat 310. When the reverse adjustment drive element 312 releases the clamping force on the first anti-slip element 311, the first anti-slip element 311 moves away from the second fixed seat 320 under the action of the second elastic element 314, and then automatically disengages from the support leg 200 so that the passenger can adjust the height of the foot pedal 300.

[0056] In an alternative embodiment, please refer to Figure 9 The first anti-slip member 311 is provided with a first fastener 3115 at one end away from the second fixed seat 320, and the two ends of the second elastic member 314 abut against the first fastener 3115 and the first fixed seat 310 respectively.

[0057] The first fastener 3115 is fixedly connected to the first anti-slip member 311. The first fastener 3115 can be a screw and is located on the side of the first fixing seat 310 away from the second fixing seat 320. The two ends of the second elastic member 314 abut against the head of the screw and the first fixing seat 310 respectively.

[0058] When the reverse adjustment drive 312 releases the clamping force on the first anti-slip member 311, the screw moves away from the second fixed seat 320 under the action of the second elastic member 314, thereby driving the first anti-slip member 311 to move away from the second fixed seat 320.

[0059] Taking the driving component 312 as the bolt 3123 and the first anti-slip component 311 including the first anti-slip plate 3111 and the connecting block 3112 as an example, the screw is fixedly connected to the connecting block 3112. When the bolt 3123 is turned in the opposite direction to release the clamping force on the connecting block 3112, the screw moves away from the second fixed seat 320 under the action of the second elastic member 314, thereby driving the first anti-slip component 311 to move away from the second fixed seat 320 as a whole. However, at this time, the first stop pin 3114 can still pass through the first anti-slip plate 3111 under the action of the first elastic member 3113 and lock in the stop hole 210 on the support leg 200.

[0060] In another alternative embodiment, please refer to Figure 4 and Figure 10 A second fastener 315 is provided on the first fixed base 310. The second fastener 315 is closer to the second fixed base 320 than the first anti-slip member 311. The two ends of the second elastic member 314 abut against the second fastener 315 and the first anti-slip member 311 respectively.

[0061] The second fastener 315 is fixedly connected to the first fixing seat 310. The second fastener 315 can be a screw and is located on the side of the first fixing seat 310 facing the second fixing seat 320. The two ends of the second elastic member 314 abut against the head of the screw and the first anti-slip member 311, respectively.

[0062] When the reverse adjustment drive 312 releases the clamping force on the first anti-slip member 311, the first anti-slip member 311 moves away from the second fixed seat 320 under the action of the second elastic member 314.

[0063] Taking the driving component 312, which includes a knob and a wedge block 3122, as an example, when the knob is rotated in the opposite direction, the knob drives the stud to rotate, and the stud drives the wedge block 3122 to move in the opposite direction. The inclined surface of the wedge block 3122 releases the pushing effect on the first anti-slip component 311, and the first anti-slip component 311 can then move away from the second fixed seat 320 under the action of the second elastic component 314.

[0064] In some embodiments, please refer to Figure 6 The second fixed seat 320 is provided with a second anti-slip member 321 on the side facing the first fixed seat 310. The driving member 312 is used to drive the first anti-slip member 311 to move toward the second fixed seat 320 so as to hold the support leg 200 between the first anti-slip member 311 and the second anti-slip member 321.

[0065] When the height of the foot pedal 300 is adjusted to the correct position, the drive component 312 drives the first anti-slip component 311 to move toward the second fixed seat 320 until the first anti-slip component 311 and the second anti-slip component 321 respectively press against the two opposite sides of the support leg 200. At this time, the foot pedal 300 and the support leg 200 are relatively fixed. The method of using double anti-slip components to frictionally lock the foot pedal 300 can further improve the stability of the foot pedal 300 when it is fixed.

[0066] In some embodiments, please refer to Figure 4 A second stop pin 322 is movably provided on the second fixed seat 320, and a third elastic member 323 is provided between the second stop pin 322 and the second fixed seat 320. The third elastic member 323 is used to make the second stop pin 322 always tend to move toward the first fixed seat 310.

[0067] The second gear pin 322 and the first anti-slip component 311 are located on both sides of the support leg 200. At this time, the support leg 200 can be tightly held between the first anti-slip component 311 and the second fixed seat 320, and can also be locked by cooperating with the second gear pin 322 through the gear hole 210.

[0068] When the second gear pin 322 is aligned with one of the gear holes 210 on the support leg 200, the second gear pin 322 can be locked into the gear hole 210 under the action of the third elastic member 323.

[0069] In an alternative embodiment, please refer to Figures 11-13 The second gear pin 322 is provided with a limiting member 3221 at the end away from the first fixed seat 310, and the second fixed seat 320 is provided with a limiting surface 324 on the side away from the first fixed seat 310. The limiting surface 324 is used to abut against the limiting member 3221.

[0070] The limiting member 3221 can be a nut. The end of the second position pin 322 away from the first fixed seat 310 is provided with a threaded section, and the nut cooperates with the threaded section. The third elastic member 323 acts on the second position pin 322 to make the second position pin 322 move toward the support leg 200. When the nut moves with the second position pin 322, it will abut against the limiting surface 324 to prevent the second position pin 322 from completely disengaging from the second fixed seat 320.

[0071] In another alternative embodiment, please refer to Figure 4 A handle 3222 is provided at the end of the second gear pin 322 that is away from the first fixed seat 310.

[0072] The end of the second gear pin 322 that is away from the first fixed seat 310 extends out of the second fixed seat 320 and is fixedly connected to the handle 3222. When it is necessary to disengage the second gear pin 322 from the gear hole 210, the handle 3222 can be pulled outward.

[0073] In some embodiments, one of the first fixing base 310 and the second fixing base 320 is provided with a pin 330, and the other is provided with a locking member 350 and a slot 340 for the pin 330 to be inserted into. The locking member 350 is used to lock the pin 330 when the pin 330 is inserted into the slot 340.

[0074] Two pins 330 can be symmetrically arranged. Correspondingly, two slots 340 and two locking members 350 are also symmetrically arranged. During the assembly of the first fixing seat 310 and the second fixing seat 320, the two pins 330 can be inserted into the two slots 340 respectively, and the two locking members 350 lock the two pins 330 respectively.

[0075] By engaging the pin 330 with the slot 340, and locking the pin 330 with the locking member 350 when the pin 330 is inserted into the slot 340, the first fixing seat 310 and the second fixing seat 320 are fixed relative to each other, thereby achieving a detachable connection between the first fixing seat 310 and the second fixing seat 320.

[0076] When it is necessary to disassemble the first fixing seat 310 and the second fixing seat 320, first release the locking member 350 from locking the pin 330, and then pull the first fixing seat 310 and the second fixing seat 320 in opposite directions until the pin 330 is completely dislodged from the slot 340.

[0077] The pin 330 is provided with a socket 331, the locking member 350 is movable relative to the first fixed seat 310 or the second fixed seat 320, and the first fixed seat 310 or the second fixed seat 320 is provided with a fourth elastic member 351, which has a tendency to insert the locking member 350 into the socket 331.

[0078] For example, the pin 330 is disposed on the first fixed base 310, the slot 340 is disposed on the second fixed base 320, the locking member 350 is movably disposed on the second fixed base 320, and the fourth elastic member 351 is disposed on the second fixed base 320 and acts on the locking member 350 to cause the locking member 350 to move into the insertion hole 331.

[0079] During the process of inserting the pin 340 into the slot 340, once the insertion hole 331 on the pin 330 is aligned with the locking member 350, the locking member 350 is inserted into the insertion hole 331 under the action of the fourth elastic member 351, thereby fixing the first fixing seat 310 and the second fixing seat 320 relative to each other.

[0080] In this embodiment, the moving direction of the locking member 350 is perpendicular to the length direction of the pin 330. It is understood that in other embodiments, the angle between the moving direction of the locking member 350 and the length direction of the pin 330 can be greater than or less than 90°, as long as the locking member 350 can lock the pin 330 during movement.

[0081] In some embodiments, please refer to Figure 14 A release handle 360 ​​is movably provided on the first fixed base 310 or the second fixed base 320. The release handle 360 ​​is provided with a guide groove 361. The locking member 350 is provided with a guide post 352 that cooperates with the guide groove 361. The moving direction of the release handle 360 ​​is perpendicular to the moving direction of the locking member 350.

[0082] The guide post 352 on the locking member 350 slides in conjunction with the guide groove 361 on the release handle 360. When the release handle 360 ​​is pulled, the guide post 352 can slide in the guide groove 361, thereby causing the locking member 350 to move in the opposite direction and compressing the fourth elastic member 351.

[0083] For example, the pin 330 is disposed on the first fixed base 310, the slot 340 is disposed on the second fixed base 320, the locking member 350 and the unlocking handle 360 ​​are both movably disposed on the second fixed base 320, and the fourth elastic member 351 is disposed on the second fixed base 320 and acts on the locking member 350.

[0084] During the process of pulling the release handle 360, the locking member 350 moves in the opposite direction, and the fourth elastic member 351 is compressed, at which point the first fixed seat 310 and the second fixed seat 320 can be disassembled.

[0085] In an optional embodiment, the locking member 350 is a locking pin, and a first guide slope 353 and a second guide slope 354 are provided at one end of the locking pin away from the fourth elastic member 351. The first guide slope 353 and the second guide slope 354 are arranged opposite to each other along the length direction of the pin 330. The release handle 360 ​​is used to drive the locking pin from the locked state to the pre-unlocked state. When the locking pin is in the locked state, the first guide slope 353 is located inside the insertion hole 331, and the second guide slope 354 is located outside the insertion hole 331. When the locking pin is in the pre-unlocked state, both the first guide slope 353 and the second guide slope 354 are located inside the insertion hole 331.

[0086] During the process of inserting the pin 330 into the slot 340, the pin 330 will first contact the first guide slope 353 and push the locking pin back a certain distance until the insertion hole 331 on the pin 330 is aligned with the locking pin. Then, the locking pin is inserted into the insertion hole 331 under the action of the fourth elastic element 351.

[0087] The first guide slope 353 has a greater slope than the second guide slope 354, which makes the locking pin, when in the locked state, as... Figure 15 As shown, the first guide slope 353 is located inside the socket 331, and the second guide slope 354 is located outside the socket 331; while the locking pin is in the pre-unlocked state, as... Figure 16 As shown, the first guide slope 353 and the second guide slope 354 are both located inside the insertion hole 331.

[0088] During the process of pulling the release handle 360 ​​to retract the locking pin, the locking pin will change from the locked state to the pre-unlocked state. At this time, the locking pin is not completely dislodged from the socket 331. The second guide slope 354 is located inside the socket 331. Pulling the first fixing seat 310 and the second fixing seat 320 in opposite directions will cause the inner wall of the socket 331 of the pin 330 to abut against the second guide slope 354 and push the locking pin to retract further until the locking pin is completely dislodged from the socket 331. Then the first fixing seat 310 and the second fixing seat 320 can be separated.

[0089] In an optional embodiment, a fifth elastic member 370 is provided on the first fixing seat 310 or the second fixing seat 320. The fifth elastic member 370 is used to act on the pin 330 when the pin 330 is inserted into the slot 340, so that the pin 330 has a tendency to move away from the slot 340.

[0090] For example, the pin 330 is disposed on the first fixed base 310, the slot 340 is disposed on the second fixed base 320, the locking member 350 and the unlocking handle 360 ​​are both movably disposed on the second fixed base 320, the fourth elastic member 351 is disposed on the second fixed base 320 and acts on the locking member 350, and the fifth elastic member 370 is also disposed on the second fixed base 320 and acts on the pin 330.

[0091] When the release handle 360 ​​is pulled to change the locking pin from the locked state to the pre-unlocked state, since the locking pin is not completely disengaged from the socket 331, the socket 330 moves a certain distance under the action of the fifth elastic element 370, but cannot disengage from the slot 340. At this time, the first anti-slip element 311 and the second fixing seat 320 release their gripping effect on the support leg 200, and the passenger can adjust the height of the foot pedal 300. After the height of the foot pedal 300 is adjusted, the first fixing seat 310 and the second fixing seat 320 are moved towards each other again, and the locking pin changes back from the pre-unlocked state to the locked state under the action of the fourth elastic element 351. The first anti-slip element 311 and the second fixing seat 320 are gripped tightly on the support leg 200 again.

[0092] It should be noted that all the above elastic elements can be selected as springs or sheet springs, and there is no limitation on this.

[0093] In summary, the embodiments of this application provide a foot pedal 300 and a seat. When the height of the foot pedal 300 needs to be adjusted, the reverse adjustment drive member 312 is used. The first anti-slip member 311 can move away from the second fixed seat 320 and disengage from the support leg 200 under the action of the second elastic member 314. At this time, the height of the foot pedal 300 can be adjusted up and down. When the height of the foot pedal 300 is adjusted to the correct position, the forward adjustment drive member 312 is used to drive the first anti-slip member 311 to move toward the second fixed seat 320 until the first anti-slip member 311 is pressed against the second fixed seat 320, thereby locking the height of the foot pedal 300.

[0094] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
