[0039] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the disclosure of this invention and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of this invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0040] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0041] Example 1

[0042] like Figure 1-4 As shown, this embodiment provides a wheelchair rowing machine 1 for training a wheelchair user, and includes a support frame 10, a wheelchair pressure member 20, a leg support member 30, a resistance mechanism 40, a hip support assembly 50, a force-applying member 70, and a display screen 80. The support frame 10 includes a front support leg 11 and a rear support leg 12. The support frame 10 is connected to a resistance mechanism 40, which is mounted on the support frame 10. In this embodiment, the resistance mechanism 40 is connected to the front of the support frame 10. The resistance mechanism 40 is used to provide motion resistance, such as an elastic member, a resistance wheel, or a resistance motor. The force-applying member 70 is connected to the resistance mechanism 40 and includes a tension rod 71 and a tension cable 72, such as a tension rope or tension chain. In this embodiment, the force-applying member 70 is arranged from front to back, so that the user pulls the force-applying member 70 backward to counteract the motion resistance provided by the resistance mechanism 40, thereby achieving an exercise effect.

[0043] Compared to ordinary people using conventional rowing machines, where the body sits on the slide rail seat of the support frame and the feet step on the pedals to perform rowing exercises, disabled people can only sit in a wheelchair and lean against one end of the wheelchair rowing machine to perform rowing exercises. Therefore, the wheelchair rowing machine 1 of this embodiment is optimized for the use scenario of disabled people sitting in a wheelchair to perform rowing exercises. Furthermore, by adding a hip support assembly 50, a counter-support force is provided to the hips or waist of the disabled user, so that during pulling training, the hips or waist are supported and can better exert force, achieving better exercise effects. In addition, by adding a wheelchair pressure piece 20, the wheelchair of the disabled user can be parked on the wheelchair pressure piece 20, thereby preventing the wheelchair rowing machine 1 from being pulled and tilted during stretching training at one end, thereby preventing safety risks.

[0044] In this embodiment, the wheelchair pressing member 20 is fixedly connected to the support frame 10. In this embodiment, the wheelchair pressing member 20 is fixedly connected between the two rear support legs 12. Of course, the wheelchair pressing member 20 can be connected to the support frame 10 in other ways, or the wheelchair pressing member 20 can be formed as one piece with the support frame 10.

[0045] The wheelchair pressing piece 20 can be a support bar matching the wheelchair wheel, or a mesh plate; in this embodiment, the wheelchair pressing piece 20 is a flat plate structure, and further, the wheelchair pressing piece 20 is a thin plate, which is convenient for pushing the wheelchair in.

[0046] The wheelchair pressure member 20 is positioned close to the floor, creating a space between the two rear support legs 12 to accommodate the wheelchair. When a disabled person, particularly one with leg impairments who requires a wheelchair, uses the wheelchair rowing machine 1, the wheelchair is parked on the wheelchair pressure member 20 and the wheels are locked using a brake mechanism. The wheelchair pressure member 20 is then pressed down by the wheelchair wheels. At this point, the user can operate the force-applying member 70 to perform exercise. The wheelchair pressure member 20 prevents the wheelchair rowing machine 1 from being pulled up during stretching exercises, which could pose a safety risk. In recent years, the resistance mechanism 40 has become increasingly lightweight. For example, the resistance mechanism 40 can also be a resistance blade or a resistance motor, significantly increasing its lightweightness. Disabled users of wheelchair rowing machines cannot use the conventional exercise method of sitting on the support frame's slide rails, and therefore cannot use their own body weight to hold down the support frame. Therefore, the provision of the wheelchair pressure member 20 on the wheelchair rowing machine 1 can prevent the safety risks associated with such lightweight resistance mechanisms 40 from being pulled up during exercise, significantly improving safety.

[0047] The rear support legs 12 include a parallel portion 121 and a connecting portion 122. The connecting portion 122 is used to connect to the main structure of the support frame 10. The parallel portions 121 of the two rear support legs 12 are arranged in parallel, and the wheelchair pressure piece 20 is connected between the parallel portions 121 of the two rear support legs 12, so that the space occupied by the wheelchair pressure piece 20 is smaller and the overall volume of the wheelchair rowing machine 1 is smaller.

[0048] The surface of the wheelchair pressing piece 20 may also be provided with an anti-skid pattern, thereby increasing the friction between the wheelchair wheel and the wheelchair pressing piece 20 , making the wheelchair more securely placed.

[0049] Reference Figure 1-4 , especially with reference to Figure 4In this embodiment, the hip support assembly 50 is connected to the support frame 10, and the angle of the hip support assembly 50 relative to the support frame 10 is adjustable, so that the hip support assembly 50 can adapt to the exercise needs of users of different heights and body shapes. Taking into account the characteristics of disabled people exerting force when sitting in a wheelchair to perform rowing exercises, the hip support assembly 50 is used to abut against the user's hip or waist. The abutting portion is located at the human body hinge that connects the upper and lower body, which can ensure that the upper body has a relatively large space for movement when the human body is in a sitting position, thereby providing a counter-support force for the user's hip or waist when the user operates the force-applying member 70 for training. When the user performs pulling training, the hip or waist is supported, so that the user can better exert force and achieve a better exercise effect.

[0050] The hip support assembly 50 includes a first mounting seat 51, a first rod assembly 55, a first angle adjustment assembly 59, a central axis 56, and a hip support member 54. The hip support member 54 is used to support the user's hip or waist, and the overall width of the hip support member 54 is roughly equal to the width of the human hip or waist. The hip support member 54 includes a flexible material for supporting the user's hip or waist. Since the human hip position has a hard hip bone support, the use of a flexible material for the hip support member 54 can increase the comfort of the hip support member 54. Further, the hip support member 54 includes an arc-shaped support surface for supporting the user's hip or waist, thereby further improving the comfort of the hip support member 54 in contact with the waist and hip. For example, in other embodiments, referring to Figure 5 The hip supporting member 54' can be in the shape of a column with a fan-shaped cross section. In this embodiment, the hip supporting member 54 is a roller 54, and the roller 54 is cylindrical.

[0051] In this embodiment, the first rod assembly 55 is a first telescopic rod assembly 55. The first mounting base 51 is fixedly mounted on the support frame 10. One end of the first telescopic rod assembly 55 is pivotally connected to the first mounting base 51, and the other end of the first telescopic rod assembly 55 is pivotally connected to the roller 54. Specifically, the other end of the first telescopic rod assembly 55 is perpendicularly connected to the middle of the central shaft 56, thereby forming a "T" shape between the central shaft 56 and the first telescopic rod assembly 55. Two rollers 54 are rotatably mounted on the central shaft 56. The rollers 54 can be made of a flexible material to enhance comfort.

[0052] like Figure 4As shown, when the user is training by operating the force-applying member 70, the user's upper body will have a certain forward and backward swing range, and the user's hips or waist will have a certain relative rotation with respect to the roller 54. Therefore, in this embodiment, the roller 54 is rotatably mounted on the central axis 56, so that the roller 54 can rotate relative to the central axis 56 following the user's hips or waist during exercise, resulting in less movement resistance and more flexible and convenient exercise.

[0053] The first telescopic rod assembly 55 is configured to have an adjustable angle relative to the first mounting seat 51 through the first angle adjustment assembly 59, thereby adjusting the spatial position of the roller 54. In other embodiments, the spatial position of the roller 54 can be adjusted by other means, such as by adjusting the overall height of the roller 54. In this embodiment, the first angle adjustment assembly 59 is used to adjust the relative angle between the first telescopic rod assembly 55 and the first mounting seat 51, thereby achieving adjustable spatial position of the roller 54. This simplifies the structure and makes processing easier. Furthermore, when the user is performing training exercises, the hip support assembly 50 is less likely to interfere with the user. Furthermore, the central axis 56 and the first telescopic rod assembly 55 form a "T"-shaped structure. This "T"-shaped structure allows space for the user's arms to move, making exercise more comfortable.

[0054] The first angle adjustment assembly 59 includes a fixed plate 58 and a movable assembly 57. The movable assembly 57 includes a movable plate 571, an elastic element 574, a pivot shaft 573, a push handle 572, and an elastic element mounting seat 575. The movable plate 571 is pivotally connected to one end of the first telescopic rod assembly 55 via the pivot shaft 573, while the fixed plate 58 is fixedly connected to the first mounting seat 51. The movable plate 571 is provided with a snap-fitting protrusion 576, and the fixed plate 58 is provided with a plurality of snap-fitting grooves 581. The snap-fitting protrusions 576 can selectively engage with the snap-fitting grooves 581, thereby enabling the first telescopic rod assembly 55 to be connected to the first mounting seat 51 at different angles. The elastic element 574 is mounted to one end of the first telescopic rod assembly 55 via the elastic element mounting seat 575. The elastic element 574 abuts one side of the movable plate 571, causing the elastic force of the elastic element 574 to securely engage the movable plate 571 with the fixed plate 58. The push handle 572 is connected to the movable plate 571. By pressing the push handle 572, the elastic force of the elastic element 574 is overcome, and the engaging protrusion 576 is separated from the engaging groove 581, thereby facilitating adjustment of the angle between the first telescopic rod assembly 55 and the first mounting base 51. After the angle is adjusted to the desired angle, the push handle 572 is released, and the movable plate 571 is reengaged with the fixed plate 58 under the elastic force of the elastic element 574. This facilitates adjustment and the structure is easy to manufacture.

[0055] The hip support assembly 50 includes a first telescopic rod assembly 55, so that the overall length of the hip support assembly 50 is adjustable, so that it can more accurately rest against the user's hip or waist, and has higher adaptability. The first telescopic rod assembly 55 includes a first tubular member 52 and a second tubular member 53 that can be telescoped and connected to each other. In this embodiment, the first tubular member 52 is sleeved within the inner cavity of the second tubular member 56. A locking mechanism 55, 521 is also provided between the first tubular member 52 and the second tubular member 56 to lock the relative position between the first tubular member 52 and the second tubular member 56. The locking mechanism includes a locking screw 55 that can be threadedly connected to the second tubular member 56 and a plurality of locking holes 521 provided on the first tubular member 52. When the locking screw 55 is screwed in, the end of the locking screw 55 can be inserted into the locking hole 521, thereby locking the relative position between the first tubular member 52 and the second tubular member 56.

[0056] Two leg support members 30 are mounted on the support frame 10 and are generally located within the wheelchair space formed between the two rear support legs 12. The leg support members 30 are configured to contact at least one leg of the user. Thus, when the wheelchair is parked on the wheelchair pressure member 20, the leg support members 30 can provide support for the legs, allowing for better exertion during movement.

[0057] Display screen 80 is mounted above support frame 10 and has multiple display areas that can display various data such as resistance, reps, power, and maximum explosive force. Display screen 7 may include a processor and memory to record previous data and settings and save each exercise record, allowing users to download data without complex operations for later analysis and research.

[0058] Example 2

[0059] like Figure 6-7 As shown, this embodiment adds an upper body support assembly 60 to the wheelchair rowing machine 1 provided in the previous embodiment, and the rest of the embodiment is the same as the first embodiment. This second embodiment is designed for use by disabled individuals whose physical conditions prevent them from swinging forward and backward. The upper body support assembly 60 is used to abut against the user's upper body, thereby providing a counter-supporting force for the user's upper body. During pulling exercises, the user's upper body is more fully supported, enabling better exertion and achieving better exercise results.

[0060] Reference Figure 6-7 The upper body support assembly 60 includes an upper body support plate 62, a second mounting base 61, a second telescopic rod assembly 65, and a second angle adjustment assembly 68. The upper body support plate 62 is mounted on one end of the second telescopic rod assembly 65, and the other end of the second telescopic rod assembly 65 is pivotally connected to the second mounting base 61.

[0061] The upper body support assembly 60 is adjustable in angle relative to the support frame 10 or the first telescopic rod assembly 55 through the second angle adjustment assembly 68, so that the upper body support assembly 60 can adapt to the exercise needs of users of different heights and body shapes.

[0062] The upper body support assembly 60 is adjustable in overall length via the second telescopic rod assembly 65, allowing it to more accurately rest against the user's upper body and provide greater adaptability. The second angle adjustment assembly 68 is similar in structure to the first angle adjustment assembly 59, and the second telescopic rod assembly 65 is similar in structure to the first telescopic rod assembly 55, so a detailed description thereof will not be repeated here.

[0063] The upper body support assembly 60 can be installed on the support frame 10 or on the first telescopic rod assembly 55. In this embodiment, refer to Figure 4-5 The upper body support assembly 60 is installed above the first telescopic rod assembly 55 through the second mounting base 61, and the second mounting base 61 is fixedly connected to the second pipe 53, so that the length and angle of the upper body support assembly 60 can be adjusted more conveniently. Moreover, since the angle of the first telescopic rod assembly 55 relative to the support frame 10 is adjustable, the upper body support assembly 60 can obtain a larger angle adjustment range relative to the support frame 10.

[0064] It should be noted that the wheelchair rowing machine 1 of this embodiment 2 can select either the upper body support component 60 or the hip support component 50 for single support, or can also select both the upper body support component 60 and the hip support component 50 for joint support.

[0065] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the form and details of the present invention without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these changes are within the scope of protection of the present invention.
