[0042] Embodiments

[0043] The embodiments of the present application provide an underwater wheelchair, which comprises a wheelchair body 1, a first connecting piece 5, a second connecting piece 4, a pedal 2 and a handrail 3. Figures 1 to 6 As shown, the wheelchair body 1 has a seat 12, a backrest 13 and a moving wheel 11; the first connecting piece 5 comprises an abutting part 53 and a rotating part 52, the rotating part 52 is rotatably connected to the backrest 13, one end of the rotating part 52 is connected to the abutting part 53 located at the back side of the backrest 13, and the other end of the rotating part 52 is connected to the handrail 3 located at the front side of the backrest 13, so as to drive the handrail 3 to reciprocate in a preset first direction by rotation; the abutting part 53 is used to limit the amplitude of reciprocation of the handrail 3.

[0044] It can be understood that when the handrail 3 is rotated to be unfolded, when it is subjected to the downward pressure of a user or external force, one side of the abutting part 53 will abut against the wheelchair body 1, which can enhance the structural strength of the handrail 3 to some extent, thereby enhancing the use safety; when the handrail 3 is rotated from unfolding to folding, the other side of the abutting part 53 will touch the wheelchair body 1, which limits the rotation range of the handrail 3.

[0045] It can be understood that when the handrail 3 is rotated to be unfolded, when it is subjected to the downward pressure of a user or external force, one side of the abutting part 53 will abut against the wheelchair body 1, which can enhance the structural strength of the handrail 3 to some extent, thereby enhancing the use safety; when the handrail 3 is rotated from unfolding to folding, the other side of the abutting part 53 will touch the wheelchair body 1, which limits the rotation range of the handrail 3.

[0046] The pedal 2 is movably connected to the wheelchair body 5 through the second connecting piece 4.

[0047] The pedal 2 and the handrail 3 are movably connected to the wheelchair body 1 respectively, and can be folded and unfolded, and have a folded state and an unfolded state, so that the underwater wheelchair has strong flexibility, which helps to meet the diversified use requirements of users, improve the comfort of users, and solve the problems of difficulty in getting on and off the wheelchair, and the handrail 3 and the pedal 2 causing obstacles to users when the underwater wheelchair is used.

[0048] The pedal 2 can be unfolded or folded relative to the second connecting piece 4, and the second connecting piece 4 can be unfolded or folded relative to the wheelchair body 1, and then the pedal 2 can be unfolded or folded relative to the wheelchair body 1. The position of the pedal 2 and the second connecting piece 4 can be adjusted as needed, the adjustment ability is strong, the adjustment mode is diversified, and the wheelchair is convenient for adapting to different environments and use scenarios.

[0049] For example, when the pedal 2 is not needed, it can be folded up, as shown in Figure 2 , to reduce the occupied space or avoid interference. The folding design of the second connecting piece 4 and the pedal 2 can significantly reduce the volume of the wheelchair, making it easier to store and transport, and saving the occupied space.

[0050] When more support in water is needed, the pedal 2 can be unfolded with the second connecting piece 4, as shown in Figure 1 , to enhance the support function of the wheelchair to the user, which helps to keep the user's position and posture stable.

[0051] When the user gets on and off the wheelchair, the pedal 2 and the armrest 3 often hinder the user, causing inconvenience to the user, which is not conducive to getting on and off the wheelchair. At this time, the pedal 2 and the second connecting piece 4 can effectively solve this problem.

[0052] The user can also adjust the angle and position of the pedal 2 and the second connecting piece 4 according to personal comfort or the needs of the use scenario; meet their own personalized needs, adjust their own posture, and optimize the user's use experience.

[0053] For example, in some embodiments of the present application, the second connecting piece 4 can be rotated from front to back, i.e. towards the direction close to the backrest 13, to complete the folding of the pedal 2; the first connecting piece can also be rotated from front to back, i.e. towards the direction away from the backrest 13, to complete the folding of the armrest 3. Of course, the specific rotation or folding mode is not limited.

[0054] Further, as shown in Figures 1 to 3 , the two ends of the second connecting piece 4 are connected to two pedals 2 respectively to realize the synchronous rotation of the two pedals 2.

[0055] It can be understood that synchronous rotation makes the two pedals 2 rotate in the same direction by the same angle, enhances the stability of the overall structure, and reduces the risk that may be caused by inconsistent movement of the pedals 2;

[0056] and reduces the complexity of independently adjusting each pedal 2. The user only needs to adjust the second connecting piece 4 to synchronously adjust the two pedals 2, simplifying the adjustment process and improving the convenience of operation;

[0057] In addition, the synchronous rotation enables the two footboards 2 to be consistent during adjustment, avoids foot discomfort caused by inconsistent height or angle of the footboards 2, and improves user comfort; the two footboards 2 are always in corresponding positions and angles, reducing accidents caused by inconsistent footboards 2, and improving use safety.

[0058] The handrail 3 is movably connected with the first connecting piece 5 to realize unfolding or folding of the handrail 3 relative to the first connecting piece 5, the first connecting piece 5 is located at an upper end of the wheelchair body 1 close to one side of the chair back 13 and is movably connected with the wheelchair body 1 to realize unfolding or folding of the handrail 3 relative to the wheelchair body 1.

[0059] It can be understood that the folding or unfolding functions of the handrail 3 relative to the first connecting piece 5 and the wheelchair body 1 and the folding or unfolding functions of the first connecting piece 5 and the wheelchair body 1 make the wheelchair more flexible, the user can adjust the position of the handrail 3 according to the user's own needs, make it more in line with the personal use habit, optimize the user experience, the handrail 3 can provide additional support when unfolded, help the user to stabilize the body, increase the safety, the handrail 3 will not hinder or interfere with the user's movement when folded, facilitate the user to get on and off the wheelchair, adjust the posture, and enhance the user's comfort during use;

[0060] and when the wheelchair needs to be stored or transported, folding the handrail 3 can reduce the occupied space, make the wheelchair more compact, and facilitate storage or transportation.

[0061] Specifically, in some embodiments of the present application, as shown in Figure 4 and Figure 5 the lower end of the wheelchair body 1 is provided with a rotating connection seat 14,

[0062] The second connecting piece 4 is provided with a rotating piece 41 matched with the shape of the rotating connection seat 14, and the rotating piece 41 is used to set in the rotating connection seat 14 to realize the rotating connection between the second connecting piece 4 and the wheelchair body 1.

[0063] The rotating connection seat 14 and the rotating piece 41 realize the rotating connection between the wheelchair body 1 and the second connecting piece 4; the connection relationship between the rotating connection seat 14 and the rotating piece 41 is relatively stable, has a certain flexibility, and limits the rotating movement, so that the second connecting piece 4 rotates along a predetermined path, the rotation between the wheelchair body 1 and the second connecting piece 4 is more stable, which can reduce the friction or wear between the second connecting piece 4 and the wheelchair body 1, and further realize a smooth rotating process.

[0064] Further, as shown in Figure 5 the side of the wheelchair body 1 provided with the rotating connection seat 14 is further provided with a limiting part 15 for limiting the rotation amplitude of the second connecting piece 4.

[0065] It can be understood that the setting of the limiting part 15 helps to control the rotatable range of the second connecting piece 4, reduces the damage to the second connecting piece 4 or the pedal 2 caused by excessive rotation, helps to improve the safety performance and structural stability of the wheelchair, and prolongs the service life of the wheelchair.

[0066] Further, as Figure 1 As shown in Figure 3 The shapes of the second connecting piece 4 and the first connecting piece 5 both include a U-shaped structure;

[0067] The U-shaped structure of the second connecting piece 4 and the first connecting piece 5 helps to realize a stable structural framework, can provide uniform support force, disperse the pressure applied on the wheelchair, can bear a larger load, reduce the possibility of bending or deformation, improve the stability of the overall structure, and thus can effectively maintain the stability of the pedal 2 and the armrest 3;

[0068] The U-shaped structure of the second connecting piece 4 and the first connecting piece 5 can also better adapt to the natural curve and sitting posture of the human body, provide more comfortable support, and reduce the discomfort of the user.

[0069] The U-shaped structure of the second connecting piece 4 and the first connecting piece 5 can also provide better rotation and adjustment capability, so that the wheelchair is more flexible to control, and the user can more conveniently adjust the position and angle of the pedal 2 and the armrest 3, thereby facilitating the adjustment of the angle and position of the wheelchair.

[0070] As shown in Figure 4 The two ends of the second connecting piece 4 extend away from the backrest 13, and are respectively provided with a rotating shaft structure 42. The pedal 2 is provided with a rotating part 21 matched with the shape of the rotating shaft structure 42. The rotating part 21 is used to be sleeved to the rotating shaft structure 42 to realize the rotating connection of the pedal 2 and the second connecting piece 4.

[0071] In some embodiments of the present application, the two ends of the first connecting piece 5 are also provided with rotating shaft structures 42 to realize the rotating connection of the armrest 3 and the first connecting piece 5.

[0072] The pedal 2 can rotate or adjust the position around the rotating shaft, so that the user can adjust the angle of the pedal 2 according to the needs, improve the comfort and functionality. The matching design of the rotating shaft and the pedal 2 makes the pedal 2 stable during rotation, reduces the shaking or loosening caused by loose connection, and thus improves the use safety;

[0073] By setting a special rotating part 21 between the rotating shaft and the pedal 2, direct friction and wear can also be reduced, thereby prolonging the service life of the pedal 2 and the support.

[0074] Further, as Figure 4As shown, the rotating shaft structure 42 is connected with an abutting piece 43, which is used to abut and support the pedal 2 after the pedal 2 is unfolded.

[0075] The abutting piece 43 can provide additional support after the pedal 2 is unfolded, optimizing the overall mechanical properties, evenly distributing the force of the pedal 2, improving the reliability and stability of the pedal 2, and avoiding the phenomenon of shaking or instability caused by uneven force or tilting of the pedal 2 during use; the support function of the abutting piece 43 makes the pedal 2 not easy to deform or sink during use, providing a more uniform pedaling experience and improving user comfort;

[0076] By sharing the load of the pedal 2 through the abutting piece 43, the direct friction and pressure between the rotating shaft and the pedal 2 can also be reduced, thereby reducing the wear of the components and prolonging the service life of the entire structure;

[0077] The support of the abutting piece 43 also allows the pedal 2 to be automatically and stably fixed in the right position when unfolded, reducing the complexity of adjustment and operation and facilitating user operation.

[0078] Further, as shown in Figure 1 and Figure 6 The top of the wheelchair body 1 away from the pedal 2 is provided with a first connecting part 16, and the first connecting part 16 is provided with a connecting shaft 161 and a connecting hole 162.

[0079] The first connecting part 5 is provided with a second connecting part 51, and the second connecting part 51 is provided with a drill hole 511 matched with the connecting shaft 161.

[0080] The connecting shaft 161 passes through the drill hole 511 and is connected to the connecting hole 162, so as to realize the rotating connection between the first connecting part 5 and the wheelchair body 1.

[0081] It can be understood that by using the connecting shaft 161 and the drill hole 511 between the first connecting part 16 and the second connecting part 51, a simple and stable rotating connection can be achieved, reducing the complex connecting components or additional support structure, and the design of the connecting shaft 161 and the connecting hole 162 provides stable connection and improves the connection stability of the first connecting part 5.

[0082] The connecting shaft 161 passes through the drill hole 511 and is connected to the connecting hole 162, so that the first connecting part 5 and the wheelchair body 1 can realize smooth rotation, which is convenient for adjusting the angle or position of the first connecting part 5, and further adjusting the posture or position of the wheelchair to adapt to different use requirements, thereby enhancing the adaptability of the wheelchair.

[0083] Further, as shown in Figure 6As shown, the first connecting part 16 is provided with a plurality of connecting holes 162 in the height direction of the wheelchair body 1, which are used to adjust the height of the first connecting part 5.

[0084] It can be understood that by adjusting the position and height of the connecting holes 162, the user can adjust the height of the first connecting part 5 according to their own needs or comfort, to adapt to different use cases or personal body types, and thus help the user adjust their posture within certain limits, significantly optimizing the user experience and improving the comfort of use.

[0085] The plurality of connecting holes 162 make height adjustment more convenient and fast, and can adjust the height of the first connecting part 5 according to changes in the wheelchair environment (such as different seat heights and terrain changes), so that the wheelchair can provide good support and stability in various environments.

[0086] By adjusting the height of the first connecting part 5, potential safety hazards caused by improper positioning of the first connecting part 5 can also be avoided, such as instability or discomfort caused by the first connecting part 5 being too high or too low.

[0087] Further, as shown, Figure 1 The water-blocking part 111 is arc-shaped and matches the size of the moving wheel 11, and is at least partially located on the upper side of the moving wheel 11.

[0088] The underwater wheelchair is often used in environments with water. When the moving wheel 11 passes over a water stain or puddle on the ground, water splashes easily due to the movement of the moving wheel 11. The water-blocking part 111 can effectively reduce the splashing of water to other parts of the wheelchair, keeping the wheelchair clean and reducing the frequency of cleaning and maintenance. It also helps to avoid water splashing on the user, improving the user's comfort.

[0089] The water-blocking part 111 matches the size of the moving wheel 11, better adapting to the structure and use requirements of the wheelchair, providing better protection while not increasing unnecessary bulk or weight of the water-blocking part 111.

[0090] In addition, the water-blocking part 111 can also help the moving wheel 11 resist a portion of external impact, protecting the moving wheel 11 and prolonging its service life, further enhancing the safety of the wheelchair.

[0091] Further, the seat 12 includes a canvas seat 12, and / or the backrest 13 includes a canvas backrest 13.

[0092] The canvas seat 12 and the canvas back 13 have strong water resistance, are suitable for underwater use, and the canvas material is not easily damaged even in a wet environment, which helps to prolong the service life of the wheelchair.

[0093] The canvas material has good comfort and soft texture while providing sufficient support to help maintain a comfortable posture of the user, and the seat 12 and the back 13 still have good comfort when used in water.

[0094] The canvas material is easy to clean, and the surface can be easily washed to maintain hygiene even after being used in water. The canvas material is also relatively light, so that the overall weight of the underwater wheelchair is light, which enhances the portability of the underwater wheelchair and facilitates operation and movement.

[0095] In addition, the canvas material has strong air permeability, which helps to accelerate the drying speed of the seat 12 and the back 13 and reduces the drying time of the wheelchair after being used in water, so that the wheelchair can be quickly restored to a dry state.

[0096] Further, as shown in Figure 3 The seat 12 is provided with a plurality of through holes 121, and all the through holes 121 are distributed in a matrix to form a through hole array 122 of mxn, where n and m are positive integers not less than 1.

[0097] The through holes 121 are arranged in a matrix to form the through hole array 122, which effectively improves air permeability, is beneficial to reduce water vapor accumulation on the seat 12, facilitates cleaning and drying of the underwater wheelchair after use, and helps to avoid bacterial growth;

[0098] The through holes 121 of the wheelchair can increase friction and reduce sliding, thereby improving the safety of the user;

[0099] The through hole array 122 helps to reduce the overall weight of the seat 12, so that the wheelchair or seat is more portable, while the structural strength and stability of the seat are not affected. The uniformly distributed through hole array 122 can also make the seat 12 more aesthetically pleasing in design and give the product a unique appearance.

[0100] The embodiment of the present application has at least the following beneficial effects:

[0101] The embodiment of the present application provides an underwater wheelchair, which has good flexibility, is convenient for reducing the hindrance to the user, is convenient for the user to use, and optimizes the use experience of the user;

[0102] Specifically, through the rotary connection of the second connecting piece 4 and the wheelchair body 1, the pedal 2 can be folded and unfolded relatively, and through the rotary connection of the first connecting piece 5 and the wheelchair body 1, the handrail 3 can be folded and unfolded relatively; so that the pedal 2 and the handrail 3 can be folded flexibly, reducing the obstruction of the pedal 2 and the handrail 3 before the user sits on the wheelchair, and facilitating the user to sit on the underwater wheelchair.

[0103] Those skilled in the art can understand that the modules in the device in the implementation scenario can be distributed in the device in the implementation scenario according to the description of the implementation scenario, and can also be changed to be located in one or more devices different from the implementation scenario. The modules of the above implementation scenario can be combined into one module, or can be further split into multiple sub-modules.

[0104] The above-mentioned serial number of the application is only for description, not representing the advantages and disadvantages of the implementation scenario.
