Description

Technical Field

[0001] This utility model relates to the field of mobility scooter technology, and in particular to a crutches storage device for electric mobility scooters. Background Technology

[0002] Currently, axillary crutches are rehabilitation assistive devices that use arm support to replace lower limb weight-bearing, suitable for patients with gait instability such as those recovering from lower limb injuries or suffering from paraplegia. Users of axillary crutches need to store them on the electric mobility scooter when using it.

[0003] However, current armpit crutch storage devices have the following technical problems:

[0004] 1. Existing armpit support storage devices are mostly designed with a fixed height (such as simple hooks or straps), which cannot accommodate the height adjustment of the seat and backrest of electric mobility scooters, as well as the length adjustment of the armpit support. This causes the bottom of the armpit support to easily touch the ground and scrape (especially on bumpy roads), or the armpit support to be too high and collide with obstacles, threatening driving safety.

[0005] Existing solutions (such as nets and universal brackets) are not adapted to the shape of the axillary crutches. During driving, the axillary crutches may sway laterally, rotate, or even fall out, forcing users to be distracted and straighten them, increasing the risk of mishandling.

[0006] 2. Existing armpit crutches storage devices use a clamp structure that only locks at a single point (e.g., only pressing one side of the backrest support rod). This makes them prone to slippage after prolonged vibration, requiring frequent readjustment. Furthermore, existing devices often use ordinary steel or plastic, which is susceptible to rust or aging after exposure to outdoor rain, leading to decreased structural strength, deformation, and breakage. This forces users to replace them frequently, increasing operating costs.

[0007] Therefore, there is a need for a crutches storage device for electric mobility scooters to solve the above-mentioned technical problems. Utility Model Content

[0008] The purpose of this invention is to provide a crutches storage device for electric mobility scooters. This device utilizes a sliding adjustable design between the saddle clip and the storage compartment, combined with a fastener tightening and loosening control mechanism, to achieve linear height adjustment of the storage compartment along the vertical part of the backrest support rod. This design allows the device to adapt to different sizes of electric mobility scooters and crutches, ensuring that the bottom of the crutches always maintains a safe distance from the ground to avoid scratches, while also preventing the armrest from being too high and affecting riding stability. Furthermore, the device provides three-dimensional stability support for the crutches during riding through the precise contact between the curved part B of the storage compartment body and the curved part A of the crutches, along with the wrapping and limiting functions of the straight parts C and D, completely solving the problems of swaying and slippage caused by traditional carrying methods.

[0009] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a groin storage device for an electric mobility scooter, including a groin clip, a storage compartment and fasteners;

[0010] The riding clip is used to be fitted onto the vertical part of the backrest support rod of the electric mobility scooter.

[0011] The storage compartment includes a mounting plate and a storage compartment body. The mounting plate abuts against the vertical part of the backrest support rod. The fastener is used to connect the saddle clip and the mounting plate of the storage compartment to allow the storage compartment to slide linearly along the vertical part of the backrest support rod, so that the bottom foot of the armpit clip stored in the storage compartment body maintains a predetermined distance from the ground.

[0012] The saddle clip and the storage compartment are fixed together by the fasteners to form a gap, and the bottom surface of the rectangular groove of the saddle clip presses against the A surface of the vertical part of the back support rod.

[0013] Furthermore, the storage container also includes a support rod, which is connected between the mounting plate and the storage container body. The storage container body includes two back plates and two side plates, with the side plates including a curved portion B and a curved portion A for supporting the armpit brace bracket.

[0014] Furthermore, the inner side of the curved portion B of the side plate abuts against the outer side of the curved portion A of the armpit brace, and the side plate also includes a straight portion C and a straight portion D, which correspond to the straight portions A and B of the armpit brace, respectively.

[0015] Furthermore, the fastener includes screws and nuts, and a plurality of screw clearance holes B are machined on the D side of the mounting plate. The screw clearance holes B are aligned with the screw clearance holes A of the saddle clamp for inserting screws.

[0016] Furthermore, both the riding clip and the storage container are made of stainless steel.

[0017] Furthermore, the gap is located between the C-side of the saddle clamp and the D-side of the mounting plate of the storage compartment. When the fastener is fully tightened, the bottom surface of the rectangular groove presses against the A-side of the vertical part of the backrest support rod, and the D-side of the mounting plate presses against the B-side of the vertical part of the backrest support rod.

[0018] The advantages of this utility model are as follows: This utility model provides a crutches storage device for electric mobility scooters, which has the following technical effects:

[0019] 1. This device utilizes a sliding adjustable design for the saddle clip and storage compartment, combined with a fastener tightness control mechanism, to achieve linear height adjustment of the storage compartment along the vertical part of the backrest support rod. This design allows the device to adapt to different sizes of electric mobility scooters and crutches, ensuring that the crutches' bottom feet always maintain a safe distance from the ground to avoid scratches, while also preventing the armrests from being too high and affecting riding stability. Furthermore, the device provides three-dimensional stability support for the crutches during riding through the precise engagement of the curved section B of the storage compartment body with the curved section A of the crutches, along with the wrapping and limiting functions of the straight sections C and D, completely solving the wobbling and slippage problems caused by traditional carrying methods.

[0020] 2. After the fasteners are tightened, this device forms a bidirectional rigid clamp on the backrest support rod, eliminating the risk of loosening caused by long-term vibration. The saddle clamp and storage compartment are both made of stainless steel, giving the device rust resistance and significantly extending its outdoor service life. Attached Figure Description

Figure 3 This is a cross-sectional view of the storage bin body in this utility model. Figure 4 This diagram shows the device installed on an electric mobility scooter, with both armpit crutches stored at the rear of the device. Figure 5 for Figure 4 Enlarged structural diagram at point B in the middle. Figure 6 This is a schematic diagram of the overall structure of an electric mobility scooter. Figure 7 This is a top-down structural diagram of the seat cushion of an electric mobility scooter. Figure 8 This is a schematic diagram of the axillary crutch. Figure 9 This is an enlarged structural diagram of the saddle clip in this utility model, as shown below. Figures 1 to 9 The invention illustrates a tweezers storage device for an electric mobility scooter, comprising a saddle clip 1, a storage compartment 2, and fasteners. The fasteners include screws 3 and nuts 4. Multiple screw clearance holes B36 are machined on the D-side 35 of the mounting plate 30, aligning with the screw clearance holes A29 of the saddle clip 1 for inserting screws 3. Screws 3 pass through screw clearance holes A29 and B36 and are engaged by nuts 4. The storage compartment 2 is allowed to slide linearly during adjustment, enabling height adjustment. The diameters of screw clearance holes A29 and B36 are 0.5mm-1mm larger than the diameter of screws 3, allowing for fine-tuning of alignment deviations during installation. The multi-hole layout disperses locking stress, preventing single-point deformation.

[0050] The storage container 2 of this utility model includes a mounting plate 30 and a storage container body 32. The mounting plate 30 abuts against the vertical portion 16 of the support rod 31. The fastener is used to connect the saddle clip 1 and the mounting plate 30 of the storage container 2, so as to allow the storage container 2 to slide linearly along the vertical portion 16 of the support rod 31, so that the bottom foot 22 of the armpit clip 6 stored in the storage container body 32 maintains a predetermined distance from the ground. The storage container body 32 is formed by welding a back plate 33 and a side plate 34 to form an armpit clip 6 receiving cavity. The inclined design of the armpit clip 6 receiving cavity makes the center of gravity of the armpit clip 6 naturally turn inward.

[0051] In this invention, the saddle clamp 1 and the storage container 2 are fixed together by the fasteners, forming a gap 40. This gap 40 is located between the C-side 28 of the saddle clamp 1 and the D-side 35 of the mounting plate 30 of the storage container 2. When the fasteners are fully tightened, the bottom surface 27 of the rectangular groove 26 presses against the A-side 17 of the vertical portion 16 of the support rod 31, and the D-side 35 of the mounting plate 30 presses against the B-side 18 of the vertical portion 16 of the support rod 31. The D-side 35 and the B-side 18 of the support rod 31 are in contact, transmitting the tightening pressure to the support rod 31 and achieving bidirectional clamping. Simultaneously, the screw clearance hole B36 is machined to ensure alignment with the hole in the saddle clamp 1. When the bottom surface 27 of the saddle clamp 1 presses against the A-side 17, the D-side 35 of the mounting plate 30 simultaneously presses against the B-side 18, forming a closed-loop force, converting vibration energy into static friction for dissipation.

[0052] In this invention, the saddle clamp 1 is used to fit onto the vertical part 16 of the support rod 31 of the electric mobility scooter 5 (the vertical part 16 serves as both the clamping object of the saddle clamp 1 and the sliding guide rail of the storage container 2, with its rectangular cross-section providing a stable guiding surface). The bottom surface 27 of the rectangular groove 26 of the saddle clamp 1 presses against the A-side 17 of the vertical part 16 of the support rod 31. The rectangular groove 26 encloses the vertical part 16 of the support rod 31 on three sides, providing the main load-bearing frame. In this invention, the gap 40 is located between the C-side 28 of the saddle clamp 1 and the D-side 35 of the mounting plate 30. When the screw 3 is tightened, the gap 40 decreases, forcing the bottom surface 27 of the saddle clamp 1 to press against the A-side 17, while the D-side 35 of the mounting plate 30 presses against the B-side 18, forming a self-locking anti-loosening structure.

[0053] The storage compartment 2 of this utility model also includes a support rod 31, which connects the mounting plate 30 and the storage compartment body 32 to bear the load of the armpit 6. The storage compartment body 32 includes two back plates 33 and two side plates 34. The side plates 34 include a curved portion B38 for supporting the curved portion A24 of the bracket 21 of the armpit 6. The curved portion B38 of the side plate 34 is precisely stamped according to the arc of the curved portion A24 of the armpit 6 bracket 21. The inner radius of curvature is 0.5mm-1mm smaller than the outer radius of curvature of the armpit 6, creating an interference fit to resist the lateral sway of the armpit 6. In this utility model, the inner side of the curved portion B38 of the side plate 34 abuts against the outer side of the curved portion A24 of the bracket 21 of the armpit 6. The side plate 34 also includes a straight portion C37 and a straight portion D39, which correspond to the straight portions A23 and B25 of the armpit 6, respectively. The straight sections C37 and D39 of the side plate 34 are parallel to the straight sections A23 and B25 of the axillary crutch 6, respectively, and the distance between them is 1mm-2mm less than the width of the axillary crutch 6 bracket 21, forming an axial constraint channel to prevent the axillary crutch 6 from rotating or shifting forward or backward.

[0054] Both the riding clip 1 and the storage container 2 in this utility model are made of stainless steel, which has good rust resistance and significantly extends the service life outdoors.

[0055] The usage process of this utility model is as follows:

[0056] 1. Device installation and initial positioning

[0057] First, fit the rectangular groove 26 of the riding clip 1 onto the vertical part 16 of the support rod 31 of the electric mobility scooter 5, so that the bottom surface 27 of the rectangular groove 26 is in contact with surface A 17 of the vertical part 16, and surface C 28 faces backward. At this time, the riding clip 1 can be temporarily stuck on the support rod 31 to prevent it from slipping off.

[0058] Then, place the D-side 35 of the mounting plate 30 of the storage compartment 2 against the B-side 18 of the vertical part 16 of the support rod 31, while aligning the screw clearance hole B36 of the mounting plate 30 with the screw clearance hole A29 of the saddle clamp 1. Pass the screw 3 through the screw clearance hole A29 of the saddle clamp 1 and the screw clearance hole B36 of the mounting plate 30, and screw in the nut 4.

[0059] 2. Height adjustment and locking

[0060] Insert the two armpit crutches 6 vertically downwards into the storage compartment body 32, ensuring that the curved portion A24 of the armpit crutch 6 bracket 21 abuts against the inner side of the curved portion B of the side plate 34 (interference allowance 0.5-1mm). The straight portions A23 and B25 should respectively engage with the constraint channels of the straight portions C37 and D39 of the side plate 34. Then, use a wrench to fully tighten the nut 4. The armpit crutches 6 can be removed or put away as follows: Storage: Insert the armpit crutches 6 vertically downwards into the storage compartment body 32. Removal: Simply lift the armpit crutches 6 upwards to disengage them from the constraint channels; no auxiliary tools are required throughout the process.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
