The following describes the implementation method of the present utility model based on its overall structure.

[0030] See also Figure 1 and Figure 2 , a lightweight wheelchair scale according to the present embodiment, comprising:

[0031] The bottom wheel 1 includes a plurality of bottom wheels 1, and the plurality of bottom wheels 1 have the same horizontal height;

[0032] The lower scale body 2 includes legs 21 at four corners of the bottom, and each leg 21 is fixedly connected to a bottom wheel 1;

[0033] Sensor 3, sensor 3 is arranged on the top of the lower scale body 2;

[0034] The upper scale body 4 is arranged on the top of the sensor 3 so that the lower scale body 2 can fully support the upper scale body 4 through the sensor 3;

[0035] A seat 5, the seat 5 is fixed to the bottom of the upper scale body 4, so that the upper scale body 4 fully supports the seat 5;

[0036] The main frames of the lower scale body 2 and the upper scale body 4 include tubes, which are made of a composite material of nylon and 20% carbon fiber. The tubes are fixedly connected by riveting through round tube connectors 8 .

[0037] By means of the above structure, compared with the existing wheelchair scale, the utility model significantly reduces the total weight of the utility model by making the tubes of the main components of the lower scale body 2 and the upper scale body 4 as the main structure of the main structure from carbon fiber reinforced nylon, and the tubes are fixedly connected by riveting through the round tube connector 8, and the assembly process is simple and the cost is low. At the same time, the tube at the top center position of the lower scale body 2 of the utility model is fixedly connected to the sensor 3, and the upper scale body 4 is fixedly connected to the center position of the sensor 3, and the frame composed of the tubes in the upper scale body 4 is used to support the seat 5, and the overall structure is simple, which is convenient for the staff to install in batches.

[0038] Specifically, the carbon fiber reinforced nylon is selected as a composite material of nylon plus 20% carbon fiber already available in the industry, which has the characteristics of high rigidity, toughness and low density, and is suitable for use in the scenario of this embodiment.

[0039] Furthermore, the lower scale body 2 starts from the leg 21, and after multiple bends, a horizontal seat surface area is formed on the top of the lower scale body 2. The sensor 3 is fixedly placed in the center of the seat surface area. Specifically, the area of ​​the sensor 3 covers the middle area of ​​the seat surface area, so that the balance of the utility model is better, and the sensor 3 can also better receive the gravity from the upper scale body 4 to achieve a more stable weight measurement result. At the same time, the bottom of the upper scale body 4 also includes a suspended footrest to provide good support for the feet of the user of the utility model. During use, the user's lower limbs can be stably placed on the footrest of the upper scale body 4 to avoid errors in weight measurement. The lower scale body 2, the upper scale body 4 and the seat 6 are all ergonomic structural shapes that are mirror-set, and fit the human limbs as closely as possible, so that this embodiment can obtain a better stability effect during the measurement process.

[0040] Furthermore, the lower scale body 2 also includes a push handle 22, and two push handles 22 are arranged on one side of the top of the lower scale body 2. Specifically, the two push handles 22 are mirror-imaged on both sides of the top of the lower scale body 2. At the same time, the push handle 22 is integrally injection-molded by PU polyurethane, has good wear resistance and good elasticity, and is sleeved on one end of the top of the lower scale body 2, so that the staff can hold the push handle 22 and push the wheelchair scale to move.

[0041] Furthermore, a weighing display instrument 6 is included, which is fixed between the two push handles 21 through a tube body, and the weighing display instrument 6 is electrically connected to the sensor 3. Specifically, the screen of the weighing display instrument 6 for displaying data results is slightly tilted and faces the face direction of the staff at the rear side of the wheelchair scale. After the user sits firmly on the seat 5, the sensor 3 is started to measure the user's weight. After the sensor 3 measures, the data is sent to the weighing display instrument 6 electrically connected thereto, so that the staff at the rear side can read the weighing value intuitively.

[0042] Furthermore, the weighing display 6 includes a shell, which is made of PP plastic material without a reinforcing rib structure, so that the weight of the weighing display 6 is further reduced, thereby reducing the total weight of the wheelchair scale, so that the staff can push the wheelchair scale more easily.

[0043] Furthermore, the bottom wheel 1 includes a wheel hub, a wheel frame and a wheel body, the wheel body 1 is fixed on the wheel hub, the wheel hub is sleeved on the wheel frame, one end of the wheel frame is inserted and fixed in the leg 21, and the wheel hub and the wheel frame are made of aluminum alloy material, and the wheel body is made of PPR material. Specifically, a total of 4 bottom wheels 1 are included, among which the first two bottom wheels 1 are fixed bottom wheels that can be pushed in one direction, and the rear two bottom wheels 1 are universal wheels, and the rear two bottom wheels 1 are arranged on one side of the push handle 22. When turning, the staff changes the angle of the push handle 22, which can drive the bottom wheel 1 below the push handle 22 to rotate and adjust the direction.

[0044] Furthermore, the seat 5 is integrally injection molded from nylon material, so that the rigidity of the seat 5 is comparable to that of aluminum alloy, but the weight is only 1 / 3 of that of aluminum alloy. As a part of the main structure, the seat 5 occupies a larger mass component, so the integrally molded nylon seat 5 can significantly reduce the total weight of the utility model.

[0045] Furthermore, it also includes armrests 7. Two armrests 7 are fixed on both sides of the top of the upper scale body 4. The armrests 7 are integrally injection-molded from PU polyurethane so that the armrests have better wear resistance and lighter weight. While providing a good supporting effect for the user's hands, the service life of the product can also be increased.

[0046] The lightweight wheelchair scale of this embodiment can use a tube composed of a composite material of nylon and 20% carbon fiber to form the lower scale body 2 and the upper scale body 4 as the main structure, which significantly reduces the total weight of the utility model, so that the staff can easily realize the displacement operation of the utility model. At the same time, the structure of the utility model is formed by stacking and fixing the lower scale body 2, the sensor 3, the upper scale body 4 and the seat 5 from bottom to top, which is easy to assemble and convenient for the staff to install in batches, and the process cost is low.

[0047] The present invention uses specific embodiments to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
