When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0028] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0029] Please see Figures 1 to 7 This utility model provides a commode wheelchair, including a wheelchair frame 1, two first universal wheels 2 disposed on the lower front side of the wheelchair frame 1, and two second universal wheels 19 disposed on the lower rear side of the wheelchair frame 1.

[0030] Furthermore, a sleeve 3 is fitted over each of the two first universal wheels 2 on the wheelchair frame 1. A foot pedal assembly 4 is disposed between the two sleeves 3, and an insertion tube 5 is disposed on the inner side of each of the two sleeves 3. The foot pedal assembly can be a molded plastic part, and the foot pedal assembly 4 includes a foot pedal 41 and arc-shaped overlapping portions 42 disposed on both sides of the foot pedal 41. The arc-shaped overlapping portions 42 are located on the inner side of the wheelchair frame 1, and an insertion plate 421 is vertically disposed at the bottom of the arc-shaped overlapping portions 42. When the foot pedal assembly 4 is assembled on the wheelchair frame 1, the insertion plate 421 is vertically inserted into the insertion tube 5, and the insertion tube 5 can support the arc-shaped overlapping portions 42 (e.g., Figure 3 (As shown).

[0031] Furthermore, each of the two arc-shaped overlapping portions 42 has an upper limit portion 422 and a lower limit portion 423 on the side facing the wheelchair frame 1. The wheelchair frame 1 has two bottom support rods parallel to the horizontal plane. When the foot pedal assembly 4 is assembled on the wheelchair frame 1, each bottom support rod is located between the upper limit portion 422 and the lower limit portion 423. Therefore, by using the bottom support rods, the downward movement range of the upper limit portion 422 can be limited, and the upward movement range of the lower limit portion 423 can also be limited. This ensures that after the foot pedal assembly 4 is assembled on the wheelchair frame 1 through the insert plate 421, the foot pedal assembly 4 will not become loose in the vertical direction, and the connection between the foot pedal assembly 4 and the wheelchair frame 1 is more reliable. When it is necessary to remove the foot pedal assembly 4 from the wheelchair frame 1, the curved overlapping part 42 (the plastic part can withstand deformation) can be bent first to separate the upper limit part 422 and the lower limit part 423 from the wheelchair frame 1. Then, the foot pedal assembly 4 can be lifted upward to allow the insert plate 421 at the bottom of the curved overlapping part 42 to come out of the insert tube 5 inside the sleeve 3. The foot pedal assembly 4 can then be removed from the wheelchair frame 1 separately. The operation is simple and convenient, which can effectively solve the problem of inconvenient disassembly of the existing toilet wheelchair foot pedal 41. This makes it easier to thoroughly clean the disassembled foot pedal assembly 4, improving cleaning convenience and hygiene.

[0032] Furthermore, because the foot pedal assembly 4 is flexible in assembly and disassembly, it can be purchased as an optional accessory. This allows users to decide whether to buy it based on their actual needs, avoiding unnecessary costs for users who do not require it, thus improving product adaptability and user freedom of choice. Moreover, the foot pedal assembly 4 can be assembled using the existing structure of the wheelchair frame 1, reducing the number of assembly parts and simplifying the overall wheelchair design.

[0033] In an optional embodiment, the distance between the upper limit portion 422 and the lower limit portion 423 is greater than the width of the bottom support rod of the wheelchair bracket 1. This design, where the distance between the upper limit portion 422 and the lower limit portion 423 is greater than the width of the bottom support rod of the wheelchair bracket 1, provides a margin of movement for one end of the arc-shaped overlapping portion 42, which has the upper limit portion 422 and the lower limit portion 423. When the insert plate 421 at the bottom of the arc-shaped overlapping portion 42 is inserted into the insert tube 5, the margin of movement allows the assembler to use external force to push one end of the arc-shaped overlapping portion 42, which has the upper limit portion 422 and the lower limit portion 423, toward the wheelchair bracket 1, thereby positioning the bottom support rod of the wheelchair bracket 1 between the upper limit portion 422 and the lower limit portion 423.

[0034] like Figure 1 , Figure 3 as well as Figure 4 As shown, in an optional embodiment, the insertion tube 5 is vertically provided with insertion holes for the insertion plate 421 to be inserted. The upper end of the insertion tube 5 is vertically provided with third limiting portions 501 on both sides of the insertion holes. The two sides of the arc-shaped overlapping portion 42 are located between the two third limiting portions 501. The third limiting portions 501 can limit the arc-shaped overlapping portion 42 in the horizontal direction, preventing the foot pedal assembly 4 from shifting or wobbling left or right during use due to wheelchair movement, bumps, or force applied by the user's feet. Combined with the limiting effects of the first and second limiting portions, this ensures that the foot pedal assembly 4 is reliably connected to the wheelchair frame 1 after assembly.

[0035] like Figure 1 and Figure 5 As shown, in an optional embodiment, the inner side of the arc-shaped overlapping part 42 is provided with a baffle 6 inclined downward. The baffle 6 is connected to the side of the foot pedal 41, which can play a lateral limiting role for the user's feet, preventing the user's feet from slipping off the side of the foot pedal 41 due to accidental shaking while riding the wheelchair, thus improving the safety of use.

[0036] like Figure 5 As shown, in an optional embodiment, the commode wheelchair further includes a seat 7 mounted on the wheelchair frame 1 and a commode 8 disposed below the seat 7; the footrest 41 is inclined downwards towards the seat 7, allowing the user's feet to hang naturally and conform to the surface of the footrest 41, preventing leg muscle tension caused by horizontal placement of the feet, improving leg comfort during long-term sitting, and reducing leg pressure. Moreover, since the footrest 41 itself maintains a downward inclined posture, there is no need to rely on complex connecting parts to flip the footrest assembly 4, thus providing a basis for the flexible assembly and disassembly of the footrest assembly 4.

[0037] like Figure 1As shown, in an optional embodiment, the seat 7 includes a main support portion 71 and a front support portion 72 located in front of the main support portion 71; the front support portion 72 has a downward arcuate surface; a seat cushion 9 is laid on the main support portion 71; when the seat cushion 9 is laid on the seat 7, the function of the wheelchair is not limited to the user's toilet use, but can also be used as a long-term mobility tool for people with mobility impairments.

[0038] Furthermore, the front side of the seat cushion 9 extends to the curved surface, which can cushion the contact pressure between the user's legs and the front support 72 of the seat plate 7, reducing the user's discomfort.

[0039] like Figure 1 As shown, in an optional embodiment, the upper two sides of the seat 7 are provided with armrests 10 respectively; wherein, the front end of one armrest 10 is fixed with an elastic male strap 11, and the front end of the other armrest 10 is fixed with an elastic female strap 12; the elastic male strap 11 and the elastic female strap 12 are detachably connected. The detachable connection can be a snap-fit ​​connection, a magnetic connection, etc. In this embodiment, by setting the elastic male strap 11 and the elastic female strap 12 at the front end of the armrest 10, when the elastic male strap 11 and the elastic female strap 12 are connected, they can effectively restrain the user from the front of the user's body, preventing the user from accidentally slipping off when the wheelchair moves, bumps, or adjusts the sitting posture, greatly improving riding safety. Moreover, the use of elastic straps can adapt to the body circumference of different users, taking into account both the fixing effect and wearing comfort.

[0040] Furthermore, this embodiment utilizes the armrest 10 structure to install the elastic male strap 11 and the elastic female strap 12, eliminating the need to add additional fixing components to the wheelchair frame 1 or seat 7 to install the elastic male strap 11 and the elastic female strap 12, thus further simplifying the overall structure of the wheelchair.

[0041] like Figure 1 As shown, in an optional embodiment, to stably install the elastic male fixing strap 11 and the elastic female fixing strap 12 on the handrail 10, a horizontal through hole 101 is provided at the front end of the handrail 10; the end of the elastic male fixing strap 11 passes through the through hole 101, and can then wrap around and be fixed to the handrail 10 from the bottom. The end of the elastic female fixing strap 12 passes through the through hole 101, and can then wrap around and be fixed to the handrail 10 from the bottom. In this embodiment, the fixing method can be either stitching or snap fasteners.

[0042] When installing the elastic male strap 11 and elastic female strap 12, the effective length of the elastic male strap 11 and elastic female strap 12 can be adjusted according to the user's needs to adapt to users with different body circumferences, improving the fit and comfort during restraint. When the elastic male strap 11 and elastic female strap 12 are damaged, they can be replaced simply by unfastening their own fixing points and pulling the corresponding strap out of the perforation 101.

[0043] like Figure 6 and Figure 7 As shown, in an optional embodiment, the lower rear end of the armrest 10 is provided with a swing rod 13, and the seat plate 7 is provided with a shaft cylinder 14 for inserting the swing rod 13, so that the armrest 10 can be flipped to the rear of the wheelchair. The shaft cylinder 14 is provided with an arc-shaped hole 141 along its circumference; the swing rod 13 is provided with a limiting pin 15 located within the arc-shaped hole 141. When the armrest 10 is flipped to the rear of the wheelchair, or when the armrest 10 is flipped forward from the rear of the wheelchair, the swing rod 13 will rotate with the armrest 10 within the shaft cylinder 14, and the limiting pin 15 can rotate with the swing rod 13 within the arc-shaped hole 141. Therefore, by using the arc-shaped hole 141 to block the limiting pin 15, the flipping angle of the armrest 10 can be limited, avoiding excessive flipping that could cause structural damage. Furthermore, the limiting pin 15 located within the arc-shaped hole 141 can enhance the stability of the connection between the armrest 10 and the seat plate 7.

[0044] like Figure 6 As shown, in an optional embodiment, the seat plate 7 is further provided with a backrest support 16; the rear side of the armrest 10 is connected to a mounting plate 17. When the armrest 10 is flipped forward from the rear of the wheelchair, the mounting plate 17 can finally fit against the backrest support 16. Therefore, the mounting plate 17 can limit the armrest 10, preventing it from continuing to flip forward after being flipped to the correct usage state. The mounting plate 17 is provided with mounting holes 171 for fixed connection with the backrest support 16. Using screws or other fasteners, the mounting plate 17 can be fixed to the backrest support 16, thereby enhancing the connection strength between the armrest 10 and the overall frame of the wheelchair. When using the wheelchair, this can prevent the user's hands from losing support, improving the safety of wheelchair use.
