Description

Technical Field

[0001] The utility model belongs to the technical field of wheelchairs, and in particular relates to a split wheelchair that can be assembled in a car. Background Art

[0002] A wheelchair is a chair with wheels that can help replace walking. It is an important means of transportation for the injured, sick, and disabled for home rehabilitation, turnover transportation, medical treatment, and outings. Wheelchairs not only meet the needs of the physically disabled and those with limited mobility, but more importantly, they facilitate family members to move and take care of patients, allowing patients to exercise and participate in social activities with the help of wheelchairs. However, for long-distance and long-term travel, they still have to take large vehicles, such as cars.

[0003] In the prior art, welfare seats have been introduced. Welfare seats can be installed in some models. The welfare seats can be extended out of the car to facilitate disabled people to sit in. However, due to the inconvenience of disabled people's own movements and the large size of wheelchairs, disabled people need to get out of the wheelchair before sitting in the car, which is extremely difficult for people with limited mobility. After sitting in, the storage of the wheelchair also requires sufficient space in the car. Although some wheelchairs can be folded, due to the presence of wheels and backrests, the volume of the wheelchair after folding in the prior art is still not ideal. Based on this, it is necessary to propose a new wheelchair to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a split wheelchair that can be assembled in a car, aiming to solve the problems in the prior art that it is difficult for disabled people to get on and off the car and the wheelchair is inconvenient to store after getting on the car.

On the one hand, when traveling by car, the disabled person does not need to get off the wheel first and then get into the vehicle, but can directly transfer from the ground to the vehicle, and the disabled person does not need to leave the seat during the whole journey. On the other hand, sharing it with the car seat is more comfortable than a traditional wheelchair. At the same time, since the upper seat is separated, the folding frame below that is responsible for walking can be further compressed in volume after folding, which is convenient for storage. Compared with the existing technology, it has significant improvement.

[0010] Further, the seat sliding connection part A comprises: two guide rails A, the two guide rails A are installed in parallel at the rotating end of the seat rotation mechanism;

[0014] Further, it also includes a guide rail positioning part A and a guide rail positioning part B, wherein the guide rail positioning part A is fixed to one end side of the guide rail A, and the guide rail positioning part B is fixed to one end side of the guide rail B corresponding to the rear of the seat, and the guide rail positioning part A and the guide rail positioning part B can be positioned and connected

[0015] A further beneficial effect of the present invention is that, by providing the guide rail positioning portion A and the guide rail positioning portion B, the guide rail A and the guide rail B can be connected together to form a complete guide rail, so that the seat sliding assembly portion can slide and transfer between the guide rail A and the guide rail B.

[0016] Further, the guide rail positioning part A is a clamping column, and the guide rail positioning part B is an open ring, and the open ring can be clamped and positioned with the clamping column.

[0017] A further beneficial effect of the utility model is that the guide rail A and the guide rail B are docked in the form of a clamping column and an open ring, thereby ensuring high docking efficiency and stability after docking.

[0018] Further, the seat sliding assembly part includes:

[0019] A sliding frame, the sliding frame includes two sliding rails arranged in parallel and a connecting rod connecting the sliding rails, the upper end surface of the sliding rail is detachably connected to the bottom of the seat, the width between the two sliding rails is consistent with the maximum width of the two guide rails B or the two guide rails A and can be converted to be slidably connected thereto.

[0020] A further beneficial effect of the utility model is that it improves the structure of the seat sliding assembly part and provides a base that can allow the seat to be transferred between two sliding connection parts. The base is installed under the seat so that the seat can slide along the two sliding connection parts, thereby ensuring that the disabled person can be smoothly transferred from the wheelchair on the ground to the car.

[0021] Furthermore, it also includes a plurality of rollers, which are rotatably connected to both sides of the slide rails, and the two guide rails B and the two guide rails A are respectively provided with rolling grooves B and rolling grooves A, and the rollers can roll along the rolling grooves B or the rolling grooves A.

[0022] A further beneficial effect of the utility model is that by setting rollers, the sliding frame can slide more smoothly on the guide rails. The rolling grooves A and rolling grooves B adapted to the rollers are respectively set on the guide rails A and guide rails B, which can play a good role in limiting and preventing the rollers from shifting during the rolling process.

[0023] Furthermore, it also includes a positioning pin, positioning holes are opened on both sides of the slide rail, and limiting holes A and limiting holes B are correspondingly opened on the rolling groove A and the rolling groove B, and the positioning pin connects the positioning hole and the limiting hole A or the limiting hole B.

[0024] A further beneficial effect of the utility model is that by setting the positioning hole, the limit hole A and the limit hole B in conjunction with the positioning pin, the sliding frame can be controlled to stay at a specific position on the guide rail A and the guide rail B, and the sliding frame can be fixed on the guide rail A or the guide rail B.

[0025] Furthermore, it also includes a card block, which is rotatably connected to one end of the slide rail, and the guide rail B and the guide rail A are respectively provided with a card slot B and a card slot A at corresponding positions, and the card block can lock the seat on the guide rail B and the guide rail A with the card slot B or the card slot A.

[0026] A further beneficial effect of the utility model is that the seat sliding assembly part is fixed on the guide rail A or the guide rail B by arranging the block and the auxiliary positioning pins of the slot A and the slot B, so as to prevent accidental injury caused by the seat sliding out of the guide rail when misoperation occurs.

[0027] Furthermore, the folding frame includes two groups of frames arranged in parallel in the vertical direction and a folding connecting rod, the folding connecting rod is located between the two groups of frames and is hinged to the two groups of frames, and the frames are provided with pedals, steering wheel assemblies and walking wheel assemblies in sequence from front to back along the direction of travel.

[0028] A further beneficial effect of the utility model is that a structurally reliable cart is provided for carrying a seat on top, and the cart can be folded by a folding connecting rod for easy storage, and because the seat on top has been moved into the cart, the folding frame can be more compact after folding and occupies less space.

[0029] Furthermore, it also includes an anti-rollover support wheel, which is located behind the walking wheel assembly, is rotatably connected to the frame and is close to the ground.

[0030] A further beneficial effect of the present invention is that the anti-rollover support wheels are arranged to contact the ground. When a person sitting on the wheelchair has his center of gravity tilted backward, the entire device may tilt backward. Especially when going uphill, the presence of the anti-rollover support wheels can effectively prevent the above situation from occurring.

[0031] In general, the utility model provides a split wheelchair that can be assembled in a car, which is characterized in that the seat of the wheelchair and the walking structure below are split structures, and a seat sliding assembly part is arranged under the separated seat, and a seat sliding connection part B and a seat sliding connection part A are respectively installed on the folding frame and the seat rotation mechanism in the car, and the seat sliding assembly part can be converted and connected between the seat sliding connection part B and the seat sliding connection part A, so that the separated seat can be directly transferred from the folding frame on the ground to the car, or from the car to the folding frame.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] See also Figure 1-Figure 4 As shown, according to the embodiment of the utility model, a split wheelchair for use in a car can be assembled, including a folding frame 1, a seat 4 and a seat sliding assembly part 5, as well as a seat sliding connection part B2 installed on the folding frame 1 and a seat sliding connection part A3 installed at the rotating end of a seat rotating mechanism 6 in the car. The seat rotating mechanism 6 is mainly used to lift the seat 4 to a suitable height and rotate the seat 4 into the interior of the car. This part of the technology is the existing technology. Cars with specific functions on the market are equipped with corresponding seat transfer devices inside, which will not be repeated here. The seat 4 can be assembled on the seat sliding connection part B2 and the seat sliding connection part A3 respectively through the seat sliding assembly part 5. When the seat 4 is assembled on the seat sliding connection part A3, it can be transferred to the interior of the car together with the rotating end of the seat rotating mechanism 6; when assembled on the seat sliding connection part B2, it can form a wheelchair with the folding frame 1.

[0051] To further improve the technical solution, the seat sliding connection part A3 includes two guide rails A31, which are arranged in parallel and bolted to the rotating end of the seat rotating mechanism 6. The seat sliding connection part B2 includes two guide rails B21, which are bolted to both sides of the upper end of the folding frame in parallel and symmetrically, and the seat sliding assembly part 5 can be slidably assembled on the guide rails B21 or the guide rails A31 and can be freely switched.

[0052] To further improve the technical solution, the seat sliding connection part A3 also includes a guide rail positioning part A, and the seat sliding connection part B2 also includes a guide rail positioning part B. The guide rail positioning part A is fixed to the side of one end of the guide rail A31, and the guide rail positioning part B is fixed to the side of one end of the guide rail B21 corresponding to the rear of the seat 4. The guide rail positioning part A and the guide rail positioning part B can be positioned and connected at the end of the guide rail B21.

[0053] Specifically, the guide rail positioning part B is an open ring 22, which is bolted to the guide rail B21, and the guide rail positioning part A is a clamping column 32, which is bolted to the guide rail A31. The open ring 22 and the clamping column 32 can be clamped. By setting the open ring 22 and the clamping column 32, the guide rail A31 and the guide rail B21 can be connected to form a complete track. The form of the open ring 22 and the clamping column 32 is not limited. In this embodiment, the groove-shaped open ring 22 and the cylindrical clamping column 32 are used to facilitate the rapid docking of the two sections of the guide rail, and at the same time ensure the stability after docking. When the docking is completed, the seat sliding assembly part 5 can slide along the guide rail B21 to the guide rail A31, or slide along the guide rail A31 to the guide rail B21, so as to transfer the seat 4 from the folding frame 1 to the vehicle, or transfer the seat 4 from the vehicle to the folding frame 1.

[0054] To further improve the technical solution, the seat sliding assembly 5 includes a rectangular sliding frame 51, the overall size of the sliding frame 51 is adapted to the size of the bottom of the seat 4, and the sliding frame 51 includes two parallel slide rails, the spacing between the two slide rails and the spacing between the two guide rails A31 and the two guide rails B21 are adapted, and can be overlapped on the two guide rails A31 or the two guide rails B21 and slide freely, and the two slide rails are fixed by a connecting rod. The upper end surfaces of the two slide rails are bolted to the bottom of the seat 4.

[0055] To further improve the technical solution, multiple rollers 52 are installed on the sides of the two slide rails. The rollers 52 can also use bearings. With the help of the rollers 52, the slide rails can move more smoothly on the guide rail B21 or the guide rail A31. At the same time, corresponding rolling grooves B23 and rolling grooves A33 are set on the guide rails B21 and A31.

[0056] Taking guide rail B21 as an example, the bottom of the rolling groove B23 is perpendicular to the track surface of guide rail B21, and the roller 52 is accommodated in the groove body. The rolling groove B23 can effectively prevent the roller 52 from deviating when moving. Correspondingly, the same setting is made on the guide rail A31, which will not be repeated here.

[0057] In order to further improve the technical solution, a positioning hole 511 is opened in the middle of the side of the two slide rails, and a limiting hole is also opened on the rolling groove B23 and the rolling groove A33. The positioning hole 511 and the limiting hole have the same diameter. Figure 2 and Figure 3The limiting hole opened on the guide rail B21 is defined as the limiting hole B24, and the limiting hole opened on the guide rail A31 is positioned as the limiting hole A34. Taking the guide rail B21 as an example, when the slide rail slides to the middle on the guide rail B21, the positioning hole 511 and the limiting hole B24 are aligned. At this time, the positioning pin 53 is allowed to pass through the positioning hole 511 and the limiting hole B24 at the same time, which can prevent the slide rail from continuing to slide along the guide rail B21, fix the slide rail and the guide rail B21 together, and then fix the seat 4 on the folding frame 1. When multiple limiting holes are opened on the guide rail A31 or the guide rail B21, the position of the slide rail fixed on the guide rail can also be adjusted. Accordingly, the method of fixing the slide rail on the guide rail A31 is the same as the method of fixing it on the guide rail B21, which will not be repeated here.

[0058] In order to further improve the technical solution, a block 54 is provided for fixing with an auxiliary positioning pin 53. In the present embodiment, there are four blocks 54 distributed at both ends of the two slide rails. Each block 54 is rotatably connected to the inner side surfaces of the two slide rails close to each other through a pin shaft. Correspondingly, grooves opened on the rail surfaces are respectively provided on the guide rail B21 and the guide rail A31. Four grooves B25 are correspondingly opened on the guide rail B21, and four grooves A35 are correspondingly opened on the guide rail A.

[0059] Taking guide rail B21 as an example, after the positioning pin 53 locks the slide rail and guide rail B21, the block 54 is moved so that the protrusion on the block 54 is inserted into the slot B25 for auxiliary fixation. When the positioning pin 53 is disengaged from the limiting hole due to misoperation, the block 54 can effectively prevent the seat 4 from sliding out of the guide rail, thereby avoiding accidents. Correspondingly, the same setting is made on the guide rail A31, which will not be repeated here.

[0060] To further improve the technical solution, a mechanism for driving the locating pin 53 is also provided in other embodiments of the utility model. Specifically, the locating pin 53 is installed in a sleeve 56, and one end of the sleeve 56 is opened and aligned with the locating hole 511 and welded to the inner side of the slide rail. The locating pin 53 is protected by the sleeve 56 and is normally in an extended state. The distance of the extended sleeve 56 is enough to pass through the locating hole 511, and the locating pin 53 can also be retracted into the sleeve 56. In this embodiment, the method of driving the locating pin 53 to retract is similar to the principle of driving the brake pad, which is achieved by a pull wire 57. The pull wire 57 is the brake wire, one end of which passes through the sleeve 56 to connect to the locating pin 53, and the other end is connected to the push rod 55. The push rod 55 is connected to the connecting rod of the sliding frame 51 in the form of a lever, so that it can rotate around a fulcrum. One end of the connected pull wire 57 is the end where the resistance arm of the lever is located. By pressing down the push rod 55, the pull wire 57 can be stretched upward, thereby driving the locating pin 53 to retract into the sleeve 56.

[0061] Taking guide rail B21 as an example, when the positioning pin 53 is retracted into the sleeve 56, the slide rail and guide rail B21 are separated. At this time, the push rod 55 performs the auxiliary pushing and pulling function, which facilitates the operator to apply force to the seat 4 to move the seat 4 on the guide rail B21. When the seat 4 needs to be fixed, wait until the positioning hole 511 and the limiting hole B24 on the guide rail B21 are aligned, release the push rod 55, reset the positioning pin 53, and pass through the positioning hole 511 and the limiting hole B24 again to fix the slide rail and guide rail B21 together, thereby fixing the seat 4 on the folding frame 1. Correspondingly, the method of fixing the seat 4 on the seat rotation mechanism 6 in the vehicle is the same. In addition to the above method, other methods can also be used to drive the positioning pin to complete the telescopic action, such as motor drive, cylinder drive or spring lock. This part of the existing technology is relatively mature and will not be repeated here.

[0062] The folding frame 1 may include two frames 11 arranged in parallel and a folding link 14 installed between the frames 11. The folding link 14 may include four articulated arms 141, which are divided into two groups with two arms in each group. The two articulated arms 141 in each group are arranged crosswise and connected by a pin at the intersection. The two groups of articulated arms 141 are placed between the two frames 11 and are respectively hinged on the two frames 11. The folding frame 1 also includes two connecting rods 142. The two groups of articulated arms 141 are arranged in parallel from the front end to the rear end of the frame 11. The connecting rod 142 is used to connect the two groups of articulated arms 141. When the articulated arms 141 rotate along the pin, the frames 11 on both sides can be driven to move closer to each other, achieving a folding effect.

[0063] A steering wheel assembly 13 and a running wheel assembly 15 are respectively arranged at the front and rear ends of the frame body 11 along the travel direction. The steering wheel assembly 13 may include a connecting column, the side of the connecting column is threadedly connected to one end of the frame body 11, and a through mounting groove is provided at the lower end of the connecting column. Universal wheels are rotatably connected to the opposite sides of the mounting groove to change the forward direction of the folding frame 1; the running wheel assembly 15 is directly rotatably connected to the rear part of the frame body 11 through the axle, and the diameter of the universal wheel hub is smaller than the diameter of the running wheel hub.

[0064] Specifically, it can also include a pair of footrests 12, a U-shaped connecting pipe fitting is installed on the connecting column of the steering wheel assembly 13, one end of the U-shaped connecting pipe fitting is fixed to the upper end of the connecting column, and the other end is arranged to be tilted downward, and a pin hole is provided thereon, and a connecting rod is vertically connected to both side ends of the footrest, and the connecting rod can be plugged into the other end of the U-shaped connecting pipe fitting, and can be locked and fixed to the connecting rod by inserting a locking pin into the pin hole.

[0065] To further improve the technical solution, an anti-rollover support wheel 16 is also provided on the frame. The anti-rollover support wheel 16 is located behind the walking wheel assembly 15, has a small diameter, and is arranged close to the ground. It can effectively prevent the folding frame 1 from tipping backward when moving, especially when going uphill.

[0066] To further improve the technical solution, the main structure of the folding frame 1, the seat sliding assembly part 5, the seat sliding connection part B2 and the seat sliding connection part A3 are all made of titanium alloy.

[0067] The utility model provides a split wheelchair that can be assembled in a car. The specific method of use is as follows: when a person with limited mobility needs to move on the ground, the seat and the folding frame below are fixed by the positioning pins, and the wheelchair is used as a normal wheelchair. When the person with limited mobility needs to get on the car, the car seat rotation mechanism is first controlled to lower the seat sliding connection part A to prepare for docking, and then the rear end of the folding frame is driven close to the car seat rotation mechanism until the seat sliding connection part B and the seat sliding connection part A are clamped together, and then the positioning pin is released, and force is applied with the help of the push rod. The seat is pushed to slide from the folding frame along the seat sliding connection part B and the seat sliding connection part A that have been connected to each other to the seat rotating mechanism in the car. When it slides to a suitable position, the locating pin is used again to fix the seat to the seat rotating mechanism. Finally, the seat rotating mechanism is controlled to move the seat into the interior of the car, and the folding frame is folded and stored. When arriving at the destination, the folded folding frame is taken out and unfolded, and the previous process is repeated in reverse to transfer the seat from the car to the folding frame and fix it. This successfully solves the problem of disabled people having difficulty getting on and off the car and the inconvenience of storing the wheelchair after getting on the car.

[0068] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
