Description

Technical Field

[0001] This utility model relates to the field of smart cane technology, specifically a multifunctional smart cane. Background Technology

[0002] The multifunctional smart cane is a new type of walking aid that integrates smart technology and multi-scenario adaptability design on the basis of the traditional cane's basic function of "assisting walking". It primarily serves the elderly, people with mobility impairments, and other groups, aiming to solve the problems of poor adaptability, limited functionality, and insufficient safety of traditional canes.

[0003] In existing technologies, relying solely on physical structure for support is insufficient to detect falls, trigger alarms, or provide location tracking. If a user falls and becomes disabled, they are forced to passively await rescue, which can easily delay intervention. There is no "location-server-contact" transmission link, meaning the user cannot actively seek help in case of an accident and must rely on passersby. In low-traffic areas, this can lead to prolonged periods without assistance. Furthermore, the lack of safety features such as alarms and health feedback, coupled with structural issues that may even increase the risk of falls, renders these technologies ineffective. The practicality is far inferior to smart canes. For example, users of different heights have varying needs for cane length, and the fixed length cannot be adjusted based on user height. Too short a length can cause users to hunch over, increasing back strain; too long a length... It requires tiptoeing for support, which can easily lead to loss of balance and even increase pressure on the lower limb joints, affecting comfort and safety. Its fixed length means it cannot be folded or shortened, taking up a lot of space when out and about, making it difficult to fit into a backpack or handbag. It can only be held by hand, which can easily cause collisions with others or hinder one's own movement. It also requires dedicated space for home storage, unlike telescopic canes which save space. In scenarios such as going up and down stairs or on uneven surfaces, the fixed length cannot be adjusted according to changes in terrain height, requiring users to frequently adjust their body posture to adapt to the cane length, increasing the risk of falls. In situations where temporary storage is needed, the fixed length may not be able to accommodate the user due to insufficient space, reducing the flexibility of use. Overall, its practicality is far inferior to that of telescopic canes. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional smart cane to solve the problem mentioned in the background art that multifunctional smart canes that cannot recognize falls or trigger alarms or location tracking reduce practicality and increase the risk of falls.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional smart cane, including a connecting support column, a handrail connecting seat fixedly connected to the connecting support column, a mounting connecting seat installed on the handrail connecting seat, a handrail body fixedly connected to one end of the handrail connecting seat, a movable adjustment component disposed on the connecting support column, universal casters installed on the movable adjustment component, a telescopic component disposed inside the handrail connecting seat, a mounting connecting shell fixedly connected inside the mounting connecting seat, a power supply body detachably installed on the mounting connecting shell, a transmission module installed inside the mounting connecting seat, a locator and a fall alarm disposed on the transmission module, a light installed on the mounting connecting seat, a protective shell detachably installed on the mounting connecting seat, and a buzzer installed on the mounting connecting seat, wherein the movable adjustment component adjusts the universal casters to extend along the ground direction.

[0006] Based on the preferred embodiment of this technical solution, the protective shell is installed directly above the transmission module, and the protective shell is inlaid in an arch shape on the mounting connector.

[0007] According to the preferred embodiment of this technical solution, the movable adjustment component includes a sliding limiting shell that is slidably connected to the connecting support column, a threaded fixing hole opened inside the sliding limiting shell, a sliding connecting sleeve that is fixedly connected to the bottom of the sliding limiting shell, a support and stabilizing frame that is fixedly connected to the outside of the sliding connecting sleeve, and a universal moving wheel that is fixedly connected to the support and stabilizing frame.

[0008] Based on the preferred embodiment of this technical solution, three support and stabilizing frames are provided, and the three support and stabilizing frames are evenly and fixedly connected to the sliding connecting sleeve.

[0009] In the preferred embodiment of this technical solution, the sliding limiting shell has a groove at the corresponding position of the connecting support column, and the sliding limiting shell slides on the connecting support column through the groove.

[0010] According to the preferred embodiment of this technical solution, the telescopic component includes a drive motor fixedly connected to the bottom of the handrail connecting seat, a rotating rod fixedly connected to the output end of the drive motor, a first gear fixedly connected to the rotating rod, a linkage double gear rotatably connected inside the handrail connecting seat, a rotating threaded rod rotatably connected inside the handrail connecting seat, a second gear fixedly connected to the rotating threaded rod, a threaded telescopic rod threadedly connected to the rotating threaded rod, and an anti-slip support pad fixedly connected to the bottom of the threaded telescopic rod. The first gear is meshed with the linkage double gear, the linkage double gear is meshed with the second gear, and the threaded telescopic rod is slidably connected inside the connecting support column.

[0011] Based on the preferred embodiment of this technical solution, a limiting slider is fixedly connected to the upper end of the threaded telescopic rod, and a groove is provided on the connecting support column at the corresponding position of the limiting slider of the threaded telescopic rod, and the limiting slider slides along the direction of the groove.

[0012] In the preferred embodiment of this technical solution, the linkage double gear is provided with two gears, and the two gears are respectively meshed and connected to the first gear and the second gear.

[0013] Based on the preferred embodiment of this technical solution, a description of the beneficial effects should be added after each paragraph, without changing the component name to a single sentence, so as to allow for the beginning of the paragraph.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In terms of safety protection, it integrates a transmission module, locator, and fall alarm. When a user falls and becomes disabled, they do not need to rely on passersby. The alarm is automatically triggered and the user's location information is displayed, effectively avoiding rescue delays. In terms of functional adaptability, it uses a connecting support column as the core support and is equipped with a mobile adjustment component with flexibly adjustable universal wheels to adapt to different mobility needs. It also integrates a lighting lamp and a buzzer to meet the functions of nighttime illumination and active assistance, respectively. Compared with the single support function of traditional canes, its practicality is significantly improved. In terms of structural design, the arch-shaped protective shell precisely covers the transmission module, providing physical protection against collisions, dust, and water without obstructing signal transmission. The scientific overall structural layout avoids the risk of falls caused by the design defects of traditional canes, and the detachable power supply unit makes daily maintenance and replacement easier.

[0016] 2. Driven by a motor, the rotating rod rotates through the transmission of the first gear, the linked double gear, and the second gear, causing the threaded rod to rotate. This allows the threaded telescopic rod to extend and retract along the connecting support column, flexibly adjusting the overall length of the cane to suit different users' heights. It meets diverse needs without requiring the cane to be replaced, offering far greater adaptability than traditional canes with fixed lengths. The limiting slider on the threaded telescopic rod slides along the groove of the connecting support column, precisely limiting its movement trajectory and preventing rotation or deviation during extension and retraction. The anti-slip support pad at the bottom increases friction with the ground, and combined with the support of the connecting support column, significantly improves the stability of the cane when standing and using it, reducing the risk of falls due to unsuitable length or unstable support. Regarding adjustment precision, the meshing transmission of the gear structure ensures stable power transmission. By adjusting the gear size ratio, the transmission ratio can be optimized, making the extension and retraction speed and stroke control of the threaded telescopic rod more precise, meeting users' fine-tuning needs for length adjustment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5This utility model provides an embodiment comprising a connecting support column 1, characterized in that it further comprises a handrail connecting seat 2 fixedly connected to the connecting support column 1, a mounting connecting seat 3 mounted on the handrail connecting seat 2, a handrail body 4 fixedly connected to one end of the handrail connecting seat 2, a movable adjustment component disposed on the connecting support column 1, universal casters 5 mounted on the movable adjustment component, a telescopic component disposed inside the handrail connecting seat 2, a mounting connecting shell 801 fixedly connected inside the mounting connecting seat 3, a power supply body 802 detachably mounted on the mounting connecting shell 801, and a transmission module mounted inside the mounting connecting seat 3. 803, a locator 804 and a fall alarm 805 installed on the transmission module 803, a light installed on the mounting connector 3, a protective shell 807 detachably installed on the mounting connector 3, and a buzzer 808 installed on the mounting connector 3. The movable adjustment component adjusts the universal caster 5 to extend along the ground direction. By integrating multiple functional components such as the connecting support column 1, the handrail connector 2, and the mounting connector 3, the cane not only has a basic support function through the connecting support column 1, but also can achieve flexible adjustment of the universal caster 5 through the movable adjustment component, meeting the user's movement needs in different scenarios.

[0025] Please see Figure 2-3 A further solution based on this embodiment is as follows: the protective shell 807 is installed directly above the transmission module 803. The protective shell 807 is arched and embedded in the mounting connector 3. By embedding the protective shell 807 in the mounting connector 3 in an arch shape and placing it directly above the transmission module 803, it can provide effective physical protection for the transmission module 803, preventing it from being corroded by external collisions, dust and moisture. At the same time, the arch-shaped design can reduce the obstruction of signal transmission by the protective shell 807, ensuring the stable operation of electronic components such as the transmission module 803, the locator 804 and the fall alarm 805, and extending the service life of the equipment.

[0026] Please see Figure 4A further solution based on this embodiment is as follows: the movable adjustment component includes a sliding limiting shell 901 slidably connected to the connecting support column 1, a threaded fixing hole 902 opened inside the sliding limiting shell 901, a sliding connecting sleeve 911 fixedly connected to the bottom of the sliding limiting shell 901, and a support and stabilizing frame 912 fixedly connected to the outside of the sliding connecting sleeve 911. The universal caster wheel 5 is fixedly connected to the support and stabilizing frame 912. By sliding the sliding limiting shell 901 on the connecting support column 1, the sliding connecting sleeve 911 and the support and stabilizing frame 912 can be driven to move up and down, thereby adjusting the height position of the universal caster wheel 5 to meet the needs of different users for the support height of the caster wheel. The threaded fixing hole 902 can be used with pins and other structures to firmly fix the sliding limiting shell 901 after adjustment, preventing displacement during use. The support and stabilizing frame 912 can provide a stable installation base for the universal caster wheel 5, ensuring stability during movement.

[0027] Please see Figure 4 A further solution based on this embodiment is as follows: three support and stabilizing frames 912 are provided, and the three support and stabilizing frames 912 are evenly fixedly connected to the sliding connecting sleeve 911. By setting three evenly distributed support and stabilizing frames 912, a stable triangular support structure can be formed in the circumferential direction, which evenly distributes the pressure borne by the universal moving wheel 5 to the sliding connecting sleeve 911 and the connecting support column 1, effectively improving the stability and balance of the cane during movement and reducing the risk of the user falling due to unstable support.

[0028] Please see Figure 4 A further solution based on this embodiment is as follows: the sliding limiting shell 901 has a groove at the corresponding position of the connecting support column 1. The sliding limiting shell 901 slides on the connecting support column 1 through the groove. By opening a groove on the sliding limiting shell 901 that matches the connecting support column 1, the sliding limiting shell 901 can slide smoothly along the axial direction of the connecting support column 1, ensuring the stability and accuracy of the adjustment process of the moving adjustment component. At the same time, the groove structure can play a good guiding and limiting role for the sliding limiting shell 901, avoiding deviation or shaking during adjustment, and ensuring the adjustment accuracy of the universal moving wheel 5.

[0029] Please see Figure 5A further embodiment of this solution is as follows: the telescopic component includes a drive motor 903 fixedly connected to the bottom of the armrest connecting seat 2, a rotating rod 904 fixedly connected to the output end of the drive motor 903, a first gear 905 fixedly connected to the rotating rod 904, a linkage double gear 906 rotatably connected inside the armrest connecting seat 2, a rotating threaded rod 908 rotatably connected inside the armrest connecting seat 2, a second gear 907 fixedly connected to the rotating threaded rod 908, a threaded telescopic rod 909 threadedly connected to the rotating threaded rod 908, and an anti-slip support pad 910 fixedly connected to the bottom of the threaded telescopic rod 909. The first gear 905 is meshed with the linkage double gear 906. The linkage double gear 906 is meshed with the second gear 907. The threaded telescopic rod 909 is slidably connected inside the connecting support column 1. The drive motor 903 drives the rotating rod 904 and the first gear 905 to rotate. The rotation is transmitted through the linkage double gear 906 to the second gear 907 and the rotating threaded rod 908, so that the threaded telescopic rod 909 can extend and retract along the inside of the connecting support column 1, thereby adjusting the overall length of the cane to meet the needs of users of different heights. The sliding limit shell 901 slides along the outside of the connecting support column 1, the threaded telescopic rod 909 slides inside the connecting support column 1, and the sliding limit shell 901 slides outside the connecting support column 1 and is fixed and limited by the threaded fixing hole 902.

[0030] Please see Figure 5 A further solution based on this embodiment is as follows: a limiting slider is fixedly connected to the upper end of the threaded telescopic rod 909, and a groove is opened at the corresponding position of the limiting slider on the connecting support column 1. The limiting slider slides along the direction of the groove. By setting a limiting slider on the threaded telescopic rod 909 and opening a corresponding groove on the connecting support column 1, the limiting slider can slide along the direction of the groove, which can effectively limit the movement trajectory of the threaded telescopic rod 909, prevent it from rotating or deviating during the extension and retraction process, ensure the stability and accuracy of the telescopic component adjustment, and at the same time prevent the threaded telescopic rod 909 from falling out of the connecting support column 1, thereby improving the safety of use.

[0031] Please see Figure 5 A further solution based on this embodiment is as follows: Two gears are provided on the linkage double gear 906, and the two gears are respectively meshed with the first gear 905 and the second gear 907. By providing two gears on the linkage double gear 906 that mesh with the first gear 905 and the second gear 907 respectively, the power transmission of the drive motor 903 can be stably transmitted, the power transmission direction can be changed, and the transmission ratio can be adjusted according to the gear size ratio, so that the extension speed and force of the threaded telescopic rod 909 are more in line with the usage requirements, and the efficient operation of the telescopic component can be guaranteed.

[0032] Working principle: The mechanical part uses the connecting support column 1 as the main frame, and the handrail connecting seat 2 and the mounting connecting seat 3 integrate the core components. During movement and adjustment, the sliding limit shell 901 slides along the groove of the connecting support column 1, driving the sliding connecting sleeve 911 and the three evenly distributed support and stabilizing frames 912 to move. The height of the universal moving wheel 5 is adjusted and locked in position through the threaded fixing hole 902 to form a stable triangular support. The telescopic function is driven by the drive motor 903, which drives the first gear 905 through the rotating rod 904, and then transmits to the second gear 907 and the rotating threaded rod 908 through the linkage double gear 906, so that the threaded telescopic rod 909 extends and retracts along the inner groove of the connecting support column 1. It works with the limit slider to prevent deviation. The anti-slip support pad 910 enhances stability. In the electronic system, the power supply body 802 supplies power to each component. The transmission module 803 connects the positioner 804 and the fall alarm 805 to monitor the position and posture in real time and automatically alarm in case of emergency. The lighting 806 provides nighttime illumination, the buzzer 808 can actively call for help, and the arch-shaped protective shell 807 protects electronic components without obstructing signals, thus integrating mechanical adjustment with intelligent safety monitoring.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
