[0031] refer to Figure 1 This application provides a non-magnetic wheelchair, which includes a seat 1, a wheelchair frame 2, a support plate 3, and a wheel assembly. The seat 1 is disposed within the wheelchair frame 2. A first sliding groove 11 is provided at the bottom of the seat 1, and the support plate 3 is disposed within the first sliding groove 11. The support plate 3 can slide back and forth along the first sliding groove 11 to extend or retract relative to the seat 1. The wheel assembly is disposed at the bottom of the wheelchair frame 2 and is used to drive the non-magnetic wheelchair to move.

[0032] This application provides a non-magnetic wheelchair. A first sliding groove 11 is provided at the bottom of the seat 1, and a support plate 3 is disposed within the first sliding groove 11. The support plate 3 can slide back and forth along the first sliding groove 11, thereby extending or retracting the support plate 3 relative to the seat 1. When a patient needs to sit in the non-magnetic wheelchair, the support plate 3 slides inward, retracting into the seat 1, making it convenient for the patient to sit in the wheelchair. After the patient sits in the wheelchair, the support plate 3 slides outward, extending, and the extended support plate 3 can support the patient's lower limbs. Therefore, the non-magnetic wheelchair of this application has the function of supporting the patient's lower limbs. For patients with orthopedic lower limb diseases, the support plate 3 can provide support for patients with orthopedic lower limb diseases, thus providing safer transportation for these patients.

[0033] Specifically, in existing technologies, patients with lower limb injuries, especially those who have undergone orthopedic lower limb surgery, require wheelchairs with lower limb support during transport. Most patients also require postoperative MRI (Magnetic Resonance Imaging) follow-up examinations, necessitating the use of a non-magnetic wheelchair for MRI scans. However, currently available non-magnetic wheelchairs lack lower limb support. While non-magnetic beds are inherently tall, patients with pre-existing lower limb conditions often face difficulties getting in and out, making the process slow and risky. This non-magnetic wheelchair addresses these issues. Patients simply stand up in the preparation area and transfer to the wheelchair, allowing for direct transport into the MRI room without any movement. This wheelchair also provides lower limb support, as is typical of orthopedic wheelchairs. Upon reaching the MRI bed, the doctor can assist the patient. The entire process requires only one medical staff member, ensuring safety and efficiency.

[0034] Specifically, the non-magnetic wheelchair of this application is made of non-magnetic materials. The seat 1, wheelchair frame 2 and tray 3 are made of wood. Wood is an environmentally friendly and renewable resource. Compared with the existing technology that uses one-piece molded plastic modules or non-magnetic alloys to make non-magnetic wheelchairs, the production cost is high and the price is expensive. One-piece molding also leads to expensive parts replacement. The non-magnetic wheelchair of this application is made of wood through mortise and tenon structure and glue combination. It will not pollute the environment, is inexpensive, and is easy to replace parts.

[0035] Specifically, the top of the support plate 3 is slightly lower than the top of the seat plate 1, making it easier for the patient to place their raised lower limb.

[0036] refer to Figure 1 The pallet 3 includes a main body 31 and a limiting part 32. The main body 31 is disposed in the first sliding groove 11, and the limiting part 32 is disposed at at least one end of the main body 31 and outside the first sliding groove 11.

[0037] refer to Figure 1 The bottom of the seat plate 1 has two first sliding grooves 11 spaced apart, and there are two support plates 3, which are respectively set in the two first sliding grooves 11. By using two support plates 3 spaced apart, it can adapt to the needs of different patients and facilitate the support of the patient's left lower limb, right lower limb, or both lower limbs at the same time.

[0038] In this embodiment, the first sliding groove 11 is formed by slotting the bottom of the seat plate 1 and the first sliding groove is provided through the axial direction of the seat plate 1. In other embodiments, the seat plate 1 is formed by bonding two plates together with glue, at least one of the plates is slotted, and the two plates are bonded together to form the first sliding groove 11 that is axially connected.

[0039] refer to Figure 1 The wheelchair frame 2 includes side panels 21 and backrest 22. There are two side panels 21, which are located on opposite sides of the seat 1. The backrest 22 is located between the two side panels 21 and is connected to the seat 1.

The side panels 21, the seat plate 1 and the backrest 22 are perpendicular to each other, and together above the seat plate 1, they form a space to accommodate the patient.

[0041] Specifically, the seat plate 1, side plate 21 and backrest plate 22 are all plate-shaped.

[0042] In this embodiment, the seat plate 1 is horizontally arranged, the two side plates 21 are vertically arranged along the length direction of the seat plate 1, and the back plate 22 is vertically arranged along the width direction of the seat plate 1.

[0043] Furthermore, the side panel 21 is also provided with through holes 23, which can promote air circulation and help dissipate heat.

[0044] Specifically, the axial direction of the first sliding groove 11 is parallel to the length direction of the seat plate 1.

[0045] In this embodiment, the limiting part 32 includes a first limiting member 33, which is disposed at the end of the main body 31 away from the backing plate 22. The first limiting member 33 is used to limit the range of movement of the main body 31 in the direction of moving closer to the backing plate 22, so as to prevent the tray 3 from disengaging from the first sliding groove 11.

[0046] Specifically, the first limiting member is approximately cylindrical.

[0047] Specifically, the thickness of the first limiting member 33 is greater than the height of the first sliding groove 11, and the thickness of the main body 31 is less than the height of the first sliding groove 11, so that the main body 31 can slide within the first sliding groove 11.

[0048] For details, please refer to Figure 3The limiting part 32 also includes a second limiting member 34, which is disposed opposite to the first limiting member 33. The second limiting member 34 is disposed at one end of the main body 31 near the backing plate 22 and on the side wall of the main body 31, so that the width of the main body 31 and the second limiting member 34 is greater than the width of the first sliding groove 11, thereby limiting the range of movement of the main body 31 in the direction away from the backing plate 22. The second limiting member 34 and the first limiting member 33 cooperate to limit the range of movement of the main body 31 on both the front and rear sides, further preventing the support plate 3 from disengaging from the first sliding groove 11.

[0049] The first limiting member 33 and the main body 31 are integrally formed. The first limiting member 33 and the main body 31 are assembled into the first sliding groove 11. After the assembly is completed, the second limiting member 34 is set at the end of the main body away from the first limiting member 33 by means of adhesive, thereby completing the assembly of the tray 3.

[0050] refer to Figure 1 The wheelchair frame 2 also includes a push handle 24, which is located at the top of the backrest 22. The push handle 24 makes it convenient for users to hold the push handle 24 to move the non-magnetic wheelchair.

[0051] Specifically, there are two push handles 24, which are respectively located at both ends of the backrest 22 for easy gripping by the user. In this embodiment, the axial direction of the push handles 24 is parallel to the length direction of the seat plate 1.

[0052] refer to Figure 1 The non-magnetic wheelchair also includes a footrest 4, which is located between the two side panels 21 and below the support plate 3 for the patient's feet to rest.

[0053] refer to Figure 1 The inner sides of the two side plates 21 are each provided with a second sliding groove 211. The two second sliding grooves 211 are arranged opposite to each other below the support plate 3. The two sides of the foot pedal 4 are respectively arranged in the second sliding grooves 211. The foot pedal 4 can move back and forth along the second sliding grooves 211 to realize the extension or retraction of the foot pedal 4 relative to the wheelchair frame 2.

[0054] Specifically, by providing foot pedal 4, the wheelchair can support the patient's feet when in a normal posture, improving the comfort of sitting in the wheelchair. When the non-magnetic wheelchair is not in use, foot pedal 4 can be retracted, which helps save storage space and facilitates transportation and storage.

[0055] refer to Figure 1 The wheelchair frame 2 also includes armrests 25, which are located at the top of the side panels 21. In this embodiment, each of the two side panels 21 has an armrest 25. Specifically, the armrests 25 are also made of wood.

[0056] refer to Figure 1 and Figure 2 The wheel assembly includes a front wheel assembly 5 and a rear wheel assembly 6, both of which are located at the bottom of the wheelchair frame 2 and are positioned opposite each other.

[0057] Specifically, the front wheel assembly 5 includes two front wheels 51, which are located on opposite sides of the front end of the wheelchair frame 2. Specifically, one front wheel 51 is located at the bottom end of one side panel 21, and the other front wheel 51 is located at the bottom end of the other side panel 21. Furthermore, the front wheels 51 are medical non-magnetic omnidirectional wheels, and each front wheel 51 can bear a weight of 50 kg.

[0058] The rear wheel assembly 6 includes two rear wheels 61 and a drive shaft 62. The two rear wheels 61 are located on opposite sides of the rear end of the wheelchair frame 2. Specifically, one rear wheel 61 is located on the outer wall of one side panel 21, and the other rear wheel 61 is located on the outer wall of the other side panel 21. The two rear wheels 61 are connected by the shaft 62. Furthermore, the drive shaft 62 passes through the two side panels 21 and is connected to the center of each of the two rear wheels 61. The drive shaft 62 is a solid wooden post. The rear wheels 61 are made of three layers of wooden wheels with progressively increasing diameters glued together from the inside out. The outer wooden wheels are fitted with solid tires of the same size to protect them.

[0059] Furthermore, the diameter of the front wheel 51 is smaller than that of the rear wheel 61, which enhances the wheelchair's flexibility, maneuverability, and user comfort. Because the front wheel 51 is smaller, the non-magnetic wheelchair has a smaller turning radius, allowing for more flexible operation in confined spaces, while the larger rear wheel 61 provides better stability and support.

[0060] refer to Figure 3 The wheel assembly also includes a brake assembly 7, which is configured to engage or disengage from the rear wheel assembly 6 to achieve braking or release of the wheel assembly.

[0061] For details, please refer to Figures 3 to 5 The brake assembly 7 includes a bolt 71. A slot 72 is provided on the side of the back plate 22 away from the seat plate 1. The slot 72 is arranged along the width direction of the back plate 22. A groove 63 is provided on the inner side of the rear wheel 61. The bolt 71 is inserted into the slot 72 and can move back and forth along the slot 72. The other end of the bolt 71 can be inserted into the groove 63 to brake the rear wheel 61, thereby braking the wheel assembly. When the other end of the bolt 71 separates from the groove 63, the rear wheel 61 is released, and the wheel assembly can continue to be pushed and moved.

[0062] Specifically, slot 72 is located above the first sliding groove 11, which facilitates operation by staff.

[0063] Specifically, there are multiple grooves 63, which are spaced apart on the inner side of the rear wheel 61. In this embodiment, the multiple grooves 63 are equidistant.

[0064] refer to Figures 4 to 5 The bolt 71 includes a connecting part 711 and a supporting part 712 connected to each other. The axial direction of the supporting part 712 is perpendicular to the axial direction of the connecting part 711. The connecting part 711 and the supporting part 712 form an "L" shape. The outer side wall of the slot 72 is also provided with a locking opening 73. The supporting part 712 extends out of the slot 72 through the locking opening 73 for the user to hold.

[0065] Specifically, the locking port 73 includes a first through port 731, a second through port 732, and a third through port 733 that are connected to each other. The second through port 732 is disposed between the third through port 733 and the first through port 731, and the second through port 732 is connected to the top of the third through port 733 and the top of the first through port 731. The width of the second through port 732 is smaller than the width of the first through port 731 and the third through port 733. The first through port 731, the second through port 732, and the third through port 733 form a U-shape. A port 731 is located on the side near the inside of the rear wheel 61. When the abutment part 712 moves into the first port 731, the end of the connecting part 711 away from the abutment part 712 is inserted into the groove 63 of the rear wheel 61, and the rear wheel 61 is braked. When the abutment part 712 moves from the first port 731, through the second port 732 to the third port 733, the end of the connecting part 711 away from the abutment part 712 separates from the groove 63, the rear wheel 61 is released, and can be pushed to move the non-magnetic wheelchair.

[0066] Furthermore, the length of the second opening 732 is greater than the depth of the groove 63, so that when the connecting part 711 moves into the third opening 733, the connecting part 711 can be completely separated from the groove 63.

[0067] In this embodiment, the first opening 731 and the third opening 733 have the same shape and dimensions. The length of the first opening 731 is slightly larger than the diameter of the supporting portion 712.

[0068] In this embodiment, there are two brake components 7. One brake component 7 is configured to abut or separate from one of the rear wheels 61, and the other brake component 7 is configured to abut or separate from the other rear wheel 61, thereby further improving the braking effect.
