Description

Technical Field

[0001] This utility model relates to the field of wheelchair technology, and in particular to a wheelchair foot pedal structure. Background Technology

[0002] In current wheelchair designs, the footrest assembly is typically rigidly connected and directly fixed to the front of the frame. The technical problem with this is that the connection between the footrest and the wheel frame lacks a folding mechanism. When not in use (such as during transport or storage), the footrest cannot be folded, resulting in an increased overall wheelchair size and space consumption, making it particularly unsuitable for storage in confined spaces (such as elevators or vehicle trunks). Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a wheelchair footrest structure.

[0004] A wheelchair foot pedal structure designed for this purpose, the wheelchair including a wheel frame, a foot pedal assembly provided on the front side of the wheel frame, the foot pedal assembly being rotatably disposed relative to the wheel frame;

[0005] The pedal assembly rotates relative to the wheel frame, and can be rotated from the use state to the folded state;

[0006] The pedal assembly is provided with a locking module, which is locked to the wheel frame to keep the pedal assembly in use.

[0007] Furthermore, the foot pedal assembly includes a connecting rod, which is connected to the foot pedal body;

[0008] A connector is provided at the end of the connecting rod away from the foot pedal body, and the connector is provided with a shaft hole;

[0009] The wheel frame is provided with a fixed seat, and a connecting shaft is provided on the fixed seat. The connecting shaft is inserted into the shaft hole.

[0010] Furthermore, the connector is provided with at least two pieces, which are spaced apart vertically;

[0011] At least two connecting shafts are provided, and they are spaced apart vertically.

[0012] The connecting shaft is inserted into the shaft hole from bottom to top for connection.

[0013] Furthermore, the locking module includes a latch that is rotatably connected to the foot pedal assembly, and the latch is provided with a locking engagement part;

[0014] The wheel frame is provided with a locking hook that engages with the locking engagement part;

[0015] The latch is provided with an elastic element, which applies a force to the latch to keep the latch in a state where the locking engagement part and the locking hook are engaged with each other.

[0016] Furthermore, the elastic element is a torsion spring, which is sleeved on the rotating shaft;

[0017] One end of the torsion spring is connected to the foot pedal assembly, and the other end is connected to the latch.

[0018] Furthermore, the upper and lower sides of the latch are provided with limiting pieces, and the locking hook is embedded in the upper and lower limiting pieces and hooks with the locking engagement part.

[0019] Compared with the prior art, the advantages of this invention are that, during use, the foot pedal assembly is locked by the locking component to remain in a locked state. When folding, the locking component is released, allowing the foot pedal assembly to rotate to the folded state, thereby reducing space occupation and facilitating operation.

[0027] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0028] See Figures 1-7A wheelchair footrest structure is disclosed. The wheelchair 10 includes a wheel frame 110, and a footrest assembly 20 is disposed on the front side of the wheel frame 110. The footrest assembly 20 is rotatably disposed relative to the wheel frame 110. The footrest assembly 20 can rotate from a used state to a folded state. A locking module 30 is disposed on the footrest assembly 20, and the locking module 30 is locked to the wheel frame 110 to keep the footrest assembly 20 in the used state. In this embodiment, when the footrest assembly is in use, it is locked by the locking module to remain in the locked state. When folding, the locking module is released, and the footrest assembly can be rotated to the folded state, thereby reducing space occupation and facilitating operation.

[0029] like Figure 3 and Figure 7 As shown, the pedal assembly 20 includes a connecting rod 220 connected to a pedal body 210; a connector 230 is provided at the end of the connecting rod 220 away from the pedal body 210, and the connector 230 has a shaft hole 240; the wheel frame 110 is provided with a fixing seat 120, and a connecting shaft 130 is provided on the fixing seat 120, which is inserted into the shaft hole 240. In this embodiment, the pedal assembly 20 can be quickly disassembled and quickly assembled. During assembly, it is achieved by inserting the connecting shaft 130 into the shaft hole 240. During disassembly, the pedal assembly 20 is lifted upwards to separate the connecting shaft 130 from the shaft hole 240. In this embodiment, the locking component not only keeps the pedal assembly in the use state, but also prevents the pedal assembly 20 from moving upwards and separating from the connecting shaft 130.

[0030] like Figure 3 As shown, at least two connectors 230 are provided, spaced vertically apart; at least two connecting shafts 130 are provided, spaced vertically apart; the connecting shafts 130 are inserted into the shaft holes 240 from bottom to top for connection. The presence of at least two connecting shafts 130 engaging with the shaft holes 240 improves connection stability.

[0031] like Figure 7 As shown, the locking module 30 includes a latch 310 rotatably connected to the foot pedal assembly 20, and the latch 310 is provided with a locking engagement portion 320; the wheel frame 110 is provided with a locking hook 330 that engages with the locking engagement portion 320; the latch 310 is provided with an elastic element, which applies a force to the latch 310 to keep the latch 310 in a state where the locking engagement portion 320 and the locking hook 330 are engaged with each other. In this embodiment, when unlocking, the latch 310 is pried open to compress the elastic element until the locking engagement portion 320 and the locking hook 330 separate, thus completing the unlocking.

[0032] In some embodiments, the elastic element is a torsion spring, which is sleeved on the rotating shaft 300; one end of the torsion spring is connected to the foot pedal assembly 20, and the other end is connected to the latch 310.

[0033] like Figure 5 and Figure 7 As shown, the upper and lower sides of the latch 310 are provided with limiting pieces 311, and the locking hook 330 is embedded in the upper and lower limiting pieces 311 and hooks with the locking engagement part 320. The limiting pieces 311 can restrict the up and down movement of the foot pedal assembly 20. When the locking hook 330 hooks with the locking engagement part 320, the limiting pieces 311 can positionally constrain the locking hook 330 to prevent the connecting shaft 130 from disengaging from the shaft hole 240.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
