[0040] To meet the diversified needs of users, a type of seat is provided with a footrest, which can be stowed and folded or unfolded. When the footrest is unfolded, it can provide support for the legs and feet of the human body, relieve fatigue, and improve comfort. After use, the footrest is in a folded state to reduce space occupation. In the related art, if the connecting structure between the footrest and the seat body is arranged directly below the cushion, the footrest is easy to conflict with the action of the cushion itself (specifically, on the one hand, the cushion needs to provide a deformation space, and the footrest arranged below the cushion will occupy the deformation space of the cushion; on the other hand, the cushion as the main force part needs to have high strength and anti-deformation ability, if the connecting structure is connected below the cushion, it is easy to interfere with the reinforcing structure of the cushion), so the footrest needs to be avoided from the cushion, if the footrest is connected to the connecting structure of the backrest of the seat, the connection position of the footrest is limited, the connection strength is insufficient, if the footrest is connected to the additionally designed connecting structure, the manufacturing cost is increased, and the design difficulty is increased.

[0041] In view of this, referring to Figures 1-6 The seat footrest structure 100 is used for a seat, and the seat footrest structure 100 can be assembled with other parts (such as a backrest, a footrest, a caster, etc.) to form a complete seat. The up, down, left, right, front, and rear directions described in the present application are all for the orientation of the user when normally using the seat, that is, after the user sits on the cushion, the direction facing is front, the direction facing back is back, and the left and right sides of the left and right hands are left and right respectively.

[0042] Specifically, the seat footrest structure 100 includes a footrest fixing part 110 and a footrest body 120. Referring to Figures 1-3The pedal fixing part 110 is formed with a through hole 111, and the cross section of the through hole 111 can be in any suitable shape according to requirements. The pedal fixing part 110 is suitable for fixedly connecting to the outer ring 210 of the cushion part 200, and is arranged in a spaced manner with the inner ring 220 of the cushion part 200. The outer ring 210 and the inner ring 220 are manufactured separately.

[0043] For the above-mentioned cushion part 200, inner ring 220 and outer ring 210. Among them, the cushion part 200 can be any suitable type of cushion, for example, one of memory foam cushion, sponge cushion, latex cushion, mesh cushion, and the cushion part 200 can contain multiple materials at the same time. The outer ring 210 and the inner ring 220 are two parts of the cushion part 200, which are manufactured separately and fixedly connected through subsequent assembly process. The outer ring 210 and the inner ring 220 after fixedly connected can be detachable or non-detachable. In addition, the outer ring 210 can completely wrap the inner ring 220 (i.e. when viewed in the vertical direction, the outer ring 210 forms a complete surrounding shape, and the inner ring 220 is completely located inside the surrounding shape), or can partially wrap the inner ring 220 (i.e. when viewed in the vertical direction, the outer ring 210 forms a surrounding shape with a notch, for example, "U" shape, and the inner ring 220 is completely located inside the surrounding shape or partially extends from the notch). Based on the above description, the pedal fixing part 110 is suitable for fixedly connecting to the outer ring 210 of the cushion part 200, that is, the position of connecting the pedal fixing part 110 and the cushion part 200 can be located on the outer side of the cushion part 200. The outer side of the cushion part 200 is not the main stress part and deformation part of the whole cushion part 200, so the above setting of the connecting position of the pedal fixing part 110 can avoid the conflict between the setting of the pedal fixing part 110 and the action of the cushion part 200 itself under the premise of connecting the cushion part 200.

[0044] In order to meet the use requirements of the pedal body 120 in different situations, referring to Figures 1-2The pedal body 120 has a storage state and a use state. The pedal body 120 is arranged in the through hole 111, so that the pedal body 120 is retracted below the outer ring 210 to be in the storage state, and the pedal body 120 is extended from below the outer ring 210 to be in the use state. The pedal body 120 specifically can include a pedal rod 122 in the form of a rod and a pedal plate 121 for placing the feet or legs of a user, so that the part arranged in the through hole 111 specifically can be the pedal rod 122. It should be noted that when the pedal body 120 is retracted below the outer ring 210, the pedal body 120 can be completely below the outer ring 210, at this time, as viewed in the direction of gravity, the pedal body 120 is completely covered by the outer peripheral contour of the cushion part 200; or the pedal body 120 can be basically below the outer ring 210, at this time, as viewed in the direction of gravity, most of the pedal body 120 is covered by the outer peripheral contour of the cushion part 200, and the remaining part of the pedal body 120 can extend to the front side or the rear side of the cushion part 200.

[0045] It can be seen that the seat pedal structure 100 of the utility model includes a pedal fixing part 110 and a pedal body 120. The pedal fixing part 110 forms a through hole 111, and the pedal fixing part 110 is adapted to be fixedly connected to the outer ring 210 of the cushion part 200 of the seat, and is arranged in spaced relation with the inner ring 220 of the cushion part 200, and the outer ring 210 and the inner ring 220 are manufactured in a separate body. The pedal body 120 has a storage state and a use state. The pedal body 120 is arranged in the through hole 111, so that the pedal body 120 is retracted below the outer ring 210 to be in the storage state, and the pedal body 120 is extended from below the outer ring 210 to be in the use state. Compared with the design in the prior art that the connecting structure between the pedal and the seat body is arranged directly below the cushion, or the design that the pedal is connected to the connecting structure of the backrest of the seat, or the design that the pedal is connected to the additionally designed connecting structure, in the scheme of the utility model, since the outer ring 210 located at the outer side of the cushion part 200 is not the main stress part and the deformation part of the whole cushion part 200, the arrangement of the pedal fixing part 110 connected to the outer ring 210 can avoid the conflict between the arrangement of the pedal fixing part 110 and the action of the cushion part 200 itself under the premise of connecting the cushion part 200. Therefore, the connection form of the seat pedal structure 100 of the utility model is more stable and convenient, and does not affect other parts of the seat.

[0046] For the specific connection form of the pedal fixing part 110, refer to Figure 1 and Figure 4In one connection form, the pedal fixing part 110 comprises a fixing structure 112 which is suitable for detachable connection with the outer ring 210. It can be understood that the fixing structure 112 is part of the pedal fixing part 110 for detachable connection with the outer ring 210, and the fixing structure 112 can form a connection directly by itself and the outer ring 210 (for example, the fixing structure 112 directly forms a snap connection with the outer ring 210), or the fixing structure 112 can be combined with other connecting members to form a connection with the outer ring 210 (for example, the fixing structure 112 and the outer ring 210 both have a hole structure, and the two are fixedly connected by screw connection or bolt connection). The detachable connection design of the fixing structure 112 can make the connection of the fixing structure 112 and the outer ring 210 more flexible, and is more convenient for the production and transportation of the seat. In another connection form, the seat pedal structure 100 further comprises an outer ring 210 which is suitable for fixed connection with the inner ring 220, and the outer ring 210 is integrally connected with the pedal fixing part 110. It should be noted that the integral connection described in the utility model can be any connection method that can connect materials into one body, such as integral molding, welding, hot melting connection, etc. The integral connection design of the fixing structure 112 can save materials, reduce manufacturing cost and reduce assembly time, and make the connection of the outer ring 210 and the pedal fixing part 110 have higher strength.

[0047] For the specific structure of the pedal fixing part 110, see Figure 3 In some embodiments, the pedal fixing part 110 comprises a first fixing part 113, a second fixing part 114 and a third fixing part 115, the first fixing part 113 forms the through hole 111, the second fixing part 114 and the third fixing part 115 are integrally connected with the first fixing part 113 at one end and are suitable for fixed connection with the outer ring 210 (for the above-mentioned connection form, it can be detachable connection or integral connection), along the gravity direction, the second fixing part 114 gradually extends to the rear side from the one end connected with the outer ring 210, and the third fixing part 115 gradually extends to the front side from the one end connected with the outer ring 210. It can be understood that the first fixing part 113, the second fixing part 114 and the third fixing part 115 are three parts integrally connected with the pedal fixing part 110, wherein the first fixing part 113 is used for the pedal body 120 to pass through, the second fixing part 114 and the third fixing part 115 are both used for fixed connection with the outer ring 210, and the above-mentioned extension direction is arranged so that the second fixing part 114 and the third fixing part 115 respectively extend to the opposite front and rear when observed in the left-right direction, so that the first fixing part 113, the second fixing part 114 and the third fixing part 115 jointly form a triangular (or approximately triangular) structure, so that the connection strength of the pedal fixing part 110 is higher.

[0048] For the material of the cushion part 200, in order to make the connection of the foot fixing part 110 more stable or the strength of the cushion part 200 higher, based on the embodiment that the outer ring 210 is fixedly connected with the foot fixing part 110, in some embodiments, the elastic modulus of the outer ring 210 is greater than that of the inner ring 220, so that the material of the outer ring 210 can be a hard material, such as one of plastic, plastic, metal, and the material of the inner ring 220 can be a soft material, such as one of memory cotton, sponge, latex, and mesh cloth. In addition, for the connection position of the foot fixing part 110 and the outer ring 210, in order to make the connection position more reasonable, see Figure 5 In some embodiments, the foot fixing part 110 is fixedly connected to the lower side front end (lower side rear position) of the outer ring 210. On the one hand, this setting can make the foot fixing part 110, as a fulcrum, closer to the user's force application point, so that the support effect of the foot fixing part 110 is better, and the foot body 120 is not easy to bend under force; on the other hand, since the length of the foot lever 122 of the foot body 120 is greater than the length of the foot plate 121, after the foot fixing part 110 is arranged at the lower side front end of the outer ring 210, the rear side of the foot plate 121 can abut against the front side of the foot fixing part 110 in the storage state of the foot body 120, and the foot lever 122 connected to the rear side of the foot plate 121 is arranged in the through hole 111, so that the foot body 120 can be positioned by the foot fixing part 110, and in the positioned storage state, the foot lever 122 accommodated in the lower side of the cushion part 200 can be designed to be longer.

[0049] In order to make the design of the seat foot structure 100 more reasonable and humanized, see Figure 3 In some embodiments, the seat foot structure 100 includes two foot fixing parts 110, and the foot body 120 includes a foot plate 121 and two foot levers 122 corresponding to the two foot fixing parts 110. The foot plate 121 can have any suitable structure shape, the cross-sectional shape of the foot lever 122 can correspond to the through hole 111, and the foot lever 122 can be a fixed-length rod or a variable-length telescopic rod. In some embodiments, along the left-right direction, the two foot fixing parts 110 are adapted to be fixedly connected to the two sides of the outer ring 210. In order to make the force more balanced, the two foot fixing parts 110 can be symmetrically arranged on the two sides of the outer ring 210 relative to the center of gravity of the cushion part 200 (or the seat foot structure 100). In order to facilitate the rotary connection of the foot body 120, see Figure 3 In some embodiments, a rod can be arranged between the two foot fixing parts 110 for the foot body 120 to pass through in the left-right direction.

[0050] Based on the above-mentioned two foot fixing parts 110, see Figure 3In some embodiments, the footboard 121 has two ends, a rotating end 1211 and a free end 1212. The rotating end 1211 is rotatably located between the two foot levers 122. In the storage state, the free end 1212 of the footboard 121 is located at the rear side of the rotating end 1211. In the use state, the free end 1212 of the footboard 121 is located at the front side of the rotating end 1211. Through the above arrangement of the position of the free end 1212, the space occupied by the footboard 121 in the storage state can be further reduced, and the storage performance of the foot body 120 is further improved.

[0051] Further, based on the above arrangement that the footboard 121 can rotate between the two foot levers 122, referring to Figures 1-2 In some embodiments, during the rotation of the foot body 120 from the storage state to the use state, at least part of the foot body 120 can pass through the area surrounded by the two foot levers 122 from the lower side of the two foot levers 122 and be located on the upper side of the two foot levers 122. In addition, the foot body 120 further comprises a limiting structure. The above arrangements enable the foot body 120 to rotate from the inner side close to the center of the cushion part 200 to the outer side that can extend below the outer ring 210 during the switching from the storage state to the use state. After the rotation to the outer side, the limiting structure is located on the lower side of the foot body 120 and can abut against the foot body 120 to block the foot body 120 from continuing to rotate downward. At this time, the foot body 120 is in the use state.

[0052] Based on the above embodiments that the two foot fixing parts 110 and the two foot levers 122 are arranged on the two sides of the outer ring 210, in order to make the above structure not hinder other parts of the seat, on the one hand, referring to Figures 5-6 In some embodiments, the seat foot structure 100 further comprises a chassis part 300 for supporting the cushion part 200. The chassis part 300 is located between the two foot fixing parts 110 and between the two foot levers 122. The chassis part 300 is arranged on the lower side of the cushion part 200, and can strengthen the connection strength or the stability of the position and shape of the cushion part 200. In some embodiments, the chassis part 300 directly contacts the lower side of the cushion part 200. In other embodiments, the chassis part 300 is spaced apart from the cushion part 200 in the up-down direction, and can contact the cushion part 200 after the cushion part 200 is deformed under the downward force. In still other embodiments, the chassis part 300 indirectly supports the cushion part 200 by connecting the frame around the cushion part 200. The above arrangements can not only support the cushion part 200 through the chassis part 300, but also make the arrangements of the chassis part 300, the foot fixing part 110 and the foot body 120 not hinder each other.

[0053] In another aspect, referring to Figure 5 In some embodiments, the seat pedal structure 100 further comprises a connecting part 400, which is capable of connecting the backrest of the seat, and is located between the two pedal fixing parts 110 and between the two pedal rods 122. The backrest of the seat is a separate component assembled, and the user connects the backrest to other parts of the seat during assembly. The connecting part 400 is used to connect the backrest and the chassis in this case. In addition, the connecting part 400 is rotatably connected to the chassis part 300, so that the connecting part 400 can adjust the angle of the backrest relative to the chassis part 300. The above arrangement can not only adjust the connecting part 400, but also make the arrangement of the connecting part 400, the pedal fixing part 110 and the pedal body 120 not interfere with each other.

[0054] The second aspect of the embodiment of the utility model also provides a seat. The seat can be any type of seat, such as an ergonomic chair, an e-sports chair, etc. Thanks to the improvement of the seat pedal structure 100 in the above embodiments, the seat of the second aspect of the embodiment of the utility model has the same technical effect as the seat pedal structure 100 in the above embodiments. Here, no further description is given.

[0055] The above is only the preferred embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made by using the content of the utility model specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model.
