Description

Technical Field

[0001] The utility model belongs to the technical field of crutch, and in particular relates to an electronic crutch. Background Art

[0002] As elderly people age, their legs and feet become less flexible, making it difficult to travel, often requiring crutches. With technological advancements, smart crutches are now available on the market, featuring multiple functional modules and more user-friendly designs. However, there are some issues, such as the fixed connection between the crutch body and the smart module, making it difficult to disassemble and replace the two. Summary of the Invention

[0003] The utility model aims to provide an electronic crutch, which solves the problem that the existing crutch body and the intelligent module are fixedly connected and the two are inconvenient to disassemble and replace.

[0004] In order to solve the above technical problems, the present invention adopts the following solutions:

[0005] The crutch comprises a crutch body and a functional component detachably arranged on the crutch body.

[0006] The functional components include a box body and a control module arranged in the box body, a battery with a charging function, and multiple functional modules; the control module is electrically connected to all functional modules through wires, and the battery supplies power to the control module and the functional modules.

[0007] The functional component of the present invention is a separate module that is detachably connected to the crutch body, making it easy to disassemble and replace. The height of the functional component can be adjusted as needed, which is highly adaptable. This solves the problem of the existing technology where the two are rigidly connected and difficult to disassemble and reposition.

[0008] Further optimization is that the outer surface of the back plate of the box is provided with a groove adapted to the crutch body, and the box is provided with at least one semicircular hoop, one end of the hoop is hinged to the box, and the other end is detachably connected to the box by a bolt; after the crutch body is embedded in the groove of the box, the bolt is tightened to fasten the two through the hoop.

[0009] If a functional component needs to be replaced, repaired, or adjusted, simply loosen the bolts and open the clamp to separate it from the crutch body. To secure the functional component to the crutch body, simply insert the crutch body into the groove in the housing and tighten the bolts to lock the clamp. This is extremely convenient. The clamp structure is simple, low-cost, and easy to operate. The grooves ensure a more compatible fit between the crutch body and the housing, ensuring a secure connection.

[0010] As a further optimization, a rubber layer is provided on the inner side of the hoop and the inner wall of the groove. The rubber layer plays a buffering and anti-slip role, thereby improving the fastening effect of the functional component and the crutch body.

[0011] Further optimization, the crutch body is a telescopic structure, including a handle, a first connecting rod, a second connecting rod, a screw and a nut; the first connecting rod is a hollow structure, the upper end of which is fixedly connected to the handle, and the lower end is fixedly connected to the nut; the upper end of the second connecting rod is fixedly connected to the lower end of the screw, the upper section of the screw extends into the cavity of the first connecting rod, the nut is sleeved on the screw, and is threadedly connected to the screw; a limiting block is provided at the upper end of the screw; the upper end of the second connecting rod is fixedly connected to a sleeve, the first connection, sleeve, nut and screw are coaxially arranged, the lower half of the first connecting rod is located in the sleeve, and the outer surface of the first connecting rod and the inner wall of the sleeve are connected in a sliding sealed manner.

[0012] When the cane needs to be extended, the elderly person grips the first and second connecting rods with both hands, then applies force to cause them to rotate relative to each other, causing the lead screw and nut to rotate, and the first connecting rod to slide along the sleeve, causing the cane to lengthen. When the cane needs to be shortened, the elderly person grips the first and second connecting rods with both hands, then applies force in opposite directions to cause them to rotate relative to each other. This is very convenient, and the threaded connection has a self-locking function, ensuring a secure connection.

[0013] By setting the sleeve, the lead screw is prevented from being exposed outside. During the relative rotation of the first connecting rod and the second connecting rod, spiral rotation also occurs between the outer surface of the first connecting rod and the inner wall of the sleeve, but the two are sealed to prevent dust from entering and are beautiful.

[0014] A limit block is provided at the upper end of the lead screw to prevent the lead screw and the first connecting rod from falling off.

[0015] Further optimization is provided on the handle with a rubber sleeve, the rubber sleeve is provided with anti-slip grooves, and the lower end of the second connecting rod is provided with an anti-slip pad to play an anti-slip role.

[0016] After further optimization, the functional modules include a vibration motor module arranged in the box, as well as an ultrasonic ranging sensor, a temperature sensor, a light sensor, a fan module, an RGB light strip, a USB interface module, an MP3 player and two switch buttons arranged on the box.

[0017] The ultrasonic ranging sensor can monitor the distance between the elderly and the object in front in real time and transmit it to the control module. When the distance is less than the set first threshold, the control module issues a command and makes a voice reminder through the MP3 player. At the same time, the vibration motor module starts to perform vibration perception.

[0018] The light sensor monitors ambient light intensity in real time. When the light intensity falls below a set second threshold, the control module activates the RGB light strip, helping seniors see the road clearly at night or in dimly lit environments, preventing falls. It also serves as a warning to passersby, preventing them from being hit.

[0019] The temperature sensor monitors the ambient temperature in real time. When the temperature exceeds a set third threshold, the control module issues a command to activate the fan module, driving the fan to cool the patient down. In addition, a switch button can be used to turn the fan module on or off. When the elderly person needs fan cooling, they can turn on the fan by pressing the switch button.

[0020] Another switch button can be used to turn on or off the MP3 player and play music independently to cultivate sentiment and cheer up the mood.

[0021] The USB interface can be used to connect peripheral components, such as updating music.

[0022] Further optimization is carried out, wherein a first magnet is fixedly provided on the box body, a second magnet is fixedly provided on the bottom of the fan module, a through hole is opened on the box body, the fan module is electrically connected to the corresponding I / O of the expansion circuit board through a telescopic spiral wire passing through the through hole, and the fan module is magnetically connected to the first magnet through the second magnet.

[0023] In the present application, the fan module is connected to the extended circuit board through a telescopic spiral wire, and the fan module is magnetically connected to the first magnet through the second magnet. When the fan is turned on in hot weather, the fan can directly blow air to cool down the top hand-held area of ​​the crutch. When the face or body part needs to be cooled, the elderly can take the fan module off the box with a little force on the bottom of the fan module, and then blow air to cool down the corresponding part. It is very flexible and does not require the entire crutch to be brought close. After that, it is only necessary to bring the fan module close to the box, and the second magnet and the first magnet will be attracted to each other, so that the fan module can be stably connected to the box. This solves the defect in the prior art that the fan and the crutch are relatively fixed and cannot be moved.

[0024] Further optimization, the control module includes a main control board and an expansion circuit board, the expansion circuit board is electrically connected to the main control board through pin-type terminal blocks; the ultrasonic ranging sensor, temperature sensor, light sensor, vibration motor module, fan module, RGB light strip, USB interface module, MP3 player, battery and two switch buttons are connected to the corresponding I / O interfaces of the expansion circuit board through wires.

[0025] Further optimization, the main control board is an Arduino UNO r3 development board, and the expansion circuit board is a sensor shieldv5.0 sensor expansion board.

[0026] In this application, it is necessary to connect multiple sensors to the Arduino UNO main control board. The I0 ports on the main control board are close together, making it difficult to connect them or easy to connect them incorrectly. There are also not enough power interfaces for various sensors and other modules. Therefore, by using an expansion board in conjunction with the UN0 R3 development board, the expansion board is directly plugged into the UN0 R3 development board. While retaining the original I0 port, each I0 port is led out. Each I0 port is equipped with an independent VCC and GND interface, making it easy to connect the sensor to the power supply. Even if more sensors are used, wiring becomes very easy, and the development difficulty is greatly reduced.

[0027] Compared with the prior art, this application has the following beneficial effects:

[0028] 1. In this application, the functional component is used as an independent module and is detachably connected to the crutch body. When the functional component needs to be replaced, repaired, or its position needs to be adjusted, the functional component and the crutch body can be separated by simply loosening the bolts and opening the clamp. When the functional component and the crutch body need to be fastened together, the crutch body is embedded in the groove of the box body and the bolts are tightened to lock the clamp. The operation is very convenient. The clamp has a simple structure, low cost, and is easy to disassemble and replace. It is also highly adaptable and solves the problem of the prior art where the two are rigidly connected, difficult to disassemble and reposition.

[0029] 2. In this application, by using the expansion board in conjunction with UN0's R3 development board, the expansion board is directly plugged into UN0's R3 development board. While retaining the original I0 port, each I0 port is then led out. Each I0 port is equipped with an independent VCC and GND interface, making it easy to connect the sensor to the power supply. Even if more sensors are used, wiring becomes very easy, reducing the difficulty of development.

[0030] 3. In this application, the fan module is connected to the expansion circuit board through a telescopic spiral wire, and the fan module is magnetically connected to the first magnet through the second magnet. When the fan is turned on in hot weather, the fan can directly blow air to cool down the top hand-held area of ​​the crutch. When the face needs to be cooled, the elderly can hold the bottom of the fan module with a little force to remove the fan module from the box, and then cool it down close to the face. It is very flexible and there is no need to bring the entire crutch close to the face. After that, you only need to bring the fan module close to the box, and the second magnet will attract the first magnet, so that the fan module can be stably connected to the box. This solves the defect in the prior art that the fan and the crutch are relatively fixed and cannot be moved. BRIEF DESCRIPTION OF THE DRAWINGS
