Description

Technical Field

[0001] This application relates to the field of trekking pole technology, specifically a multifunctional trekking pole. Background Technology

[0002] Currently available trekking poles and ski poles have relatively limited functions, primarily providing mechanical support and shock absorption, which limits their use at night or in low-visibility environments. When hiking, skiing, or trekking at night, users usually need to carry additional lighting equipment such as headlamps and flashlights. This not only increases the burden of carrying them but also restricts the freedom of movement of the hands and reduces visibility in the environment, posing safety hazards.

[0003] Furthermore, in group activities such as ski lessons and night hiking, instructors or leaders often struggle to quickly identify members of different groups and skill levels, lacking effective visual differentiation methods, which hinders on-site management and safety. Although some external devices or wearable equipment with light-emitting functions exist, most are not integrated with the trekking poles or ski poles themselves, resulting in problems such as inconvenient installation, easy detachment, affecting the feel of use, and compromising the structural strength of the poles.

[0004] While there have been occasional attempts to add external lighting devices to poles in existing technologies, these devices are often structurally crude, offer poor protection, and are ill-suited to the complex and ever-changing outdoor environment. They are particularly prone to damage under conditions of extreme cold, humidity, and impact. Furthermore, these external lighting devices often compromise grip comfort and lack intelligent features such as multi-color adjustment, failing to meet the comprehensive demands of modern outdoor sports for safety, functionality, and aesthetics.

[0005] Therefore, it is necessary to develop a multi-functional trekking pole that is highly integrated, feature-rich, easy to use, and does not affect the original performance. This pole would provide basic support while also offering various practical functions such as lighting, signaling, and identification, thereby enhancing the exercise experience and safety at night and in inclement weather. Utility Model Content

[0006] This application integrates lighting, signaling, and trekking poles into one unit, significantly improving safety, visibility, and ease of use at night and in harsh environments without sacrificing their original support and adjustment functions.

[0007] To achieve the above objectives, this application provides the following technical solution: a multifunctional trekking pole, comprising a hollow pole body; a strip groove is provided on the outer side of the hollow pole body, an LED light strip is installed inside the strip groove, a handle is installed at the upper end of the hollow pole body, a lithium battery pack and a controller are provided inside the handle, a protective cavity is provided at the upper end of the handle, and a control switch group is provided inside the protective cavity.

[0008] The hollow rod body consists of a cylindrical hollow outer rod and a cylindrical hollow inner rod. The cylindrical hollow inner rod is sleeved inside the cylindrical hollow outer rod, and the outer side of the cylindrical hollow inner rod is connected to the inner side of the cylindrical hollow outer rod by strip ribs.

[0009] Preferably, a sealing end cap is threaded to the upper end of the outer side surface of the protective cavity.

[0010] Preferably, the outer side of the handle is provided with an anti-slip ring, the lower end of the outer side of the handle is provided with an annular baffle, and the upper end of the outer side of the handle is provided with an anti-loss rope.

[0011] Preferably, the lower end of the hollow rod is provided with a bottom annular plate and a shock-absorbing rod, the shock-absorbing rod is slidably connected to a cylindrical groove provided at the lower end of the hollow rod, and a spring is provided at the upper end of the inner side of the cylindrical groove.

[0012] Preferably, the number of the strip grooves is not less than one, and each strip groove is provided with an LED light strip inside.

[0013] Preferably, the hollow rod body includes a first rod section, a second rod section is sleeved on the inner side of the first rod section, a third rod section is sleeved on the inner side of the second rod section, and a locking mechanism is provided at the connection between the first rod section and the second rod section, and at the connection between the second rod section and the third rod section.

[0014] Preferably, the locking mechanism includes an external threaded sleeve, an internal threaded sleeve is threadedly connected to the outer side of the external threaded sleeve, a plurality of strip grooves are provided at the lower end of the outer side of the external threaded sleeve, the lower end of the outer side of the external threaded sleeve is inverted conical, and the lower end of the inner side of the internal threaded sleeve is conical.

[0015] Preferably, the hollow rod body includes a sleeve, the lower end face of the sleeve is connected to a second sleeve by a spring pin, and the lower end face of the second sleeve is connected to a third sleeve by a spring pin.

[0016] Preferably, the control switch group includes a mode switching button and a brightness adjustment button. The controller is electrically connected to the LED light strip and is used to control the light emission mode and brightness level of the LED light strip. The light emission modes include three types: constant light, flashing, and SOS distress signal.

[0017] Preferably, the protective cavity is provided with a replaceable battery compartment and a USB charging port on its side. The lithium battery pack is connected to an external power source through the USB charging port for charging or powering external devices.

[0018] Compared with the prior art, the beneficial effects of this application are:

[0019] 1. This application integrates multiple LED light strips on the hollow pole body and is powered by a controller and lithium battery pack inside the handle. The trekking pole itself can be used as a powerful lighting or signaling tool. Users do not need to carry an additional flashlight or headlamp, freeing up their hands. At the same time, the bright light-emitting pole body makes hikers, skiers or group members easily visible to companions or rescuers in the dark, effectively reducing safety risks and facilitating team organization and management.

[0020] 2. This design cleverly integrates the lighting system, power supply, and control system into the pole body and handle, resulting in a simple and streamlined appearance. By adopting a telescopic hollow pole body equipped with a reliable locking mechanism and a spring shock-absorbing structure at the bottom of the pole body, it ensures that the original core mechanical performance of the trekking pole, such as length adjustment, stable support, and shock absorption, is completely unaffected, achieving functional superposition rather than functional compromise.

[0021] 3. The protective cavity and its sealed end cap provide dust and water protection for the control switch assembly; the anti-loss rope, anti-slip ring and ring baffle and other humanized designs improve grip comfort and anti-drop safety; the built-in USB charging port allows users to charge the lithium battery pack at any time, and can even provide emergency power for other devices; these detailed designs together ensure that this multi-functional trekking pole can adapt to complex and harsh outdoor environments, extend its service life, and provide a convenient and reliable all-weather use experience.

Detailed Implementation

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] In the description of this application, when a feature is referred to as "setting", "fixing", or "connecting" to another feature, it can be set, fixed, or connected to the other feature directly, or it can be set, fixed, or connected to the other feature indirectly.

[0035] Please see Figure 1-6 10. This application provides the following technical solution: a multi-functional hiking stick, including a hollow pole body 2; the outer side of the hollow pole body 2 is provided with a strip groove, an LED light strip 1 is installed inside the strip groove, a handle 9 is installed at the upper end of the hollow pole body 2, a lithium battery pack 10 and a controller 11 are provided inside the handle 9, a protective cavity 7 is provided at the upper end of the handle 9, and a control switch group 13 is provided inside the protective cavity 7;

[0036] The hollow rod body 2 consists of a cylindrical hollow outer rod and a cylindrical hollow inner rod. The cylindrical hollow inner rod is sleeved inside the cylindrical hollow outer rod, and the outer side of the cylindrical hollow inner rod is connected to the inner side of the cylindrical hollow outer rod by strip ribs.

[0037] Specifically, one or more longitudinal grooves are formed along the axial direction on the outer surface of the hollow rod 2. The cross-sectional shape of the groove is arc-shaped, and its depth is designed to just accommodate the thickness of the LED light strip 1, so that after installation, the light-emitting surface of the LED light strip 1 is basically flush with or slightly protruding from the outer surface of the rod, thereby reducing the risk of scratches and optimizing the light emission effect. The LED light strip 1 is fixed in the groove with waterproof adhesive.

[0038] The handle 9 has a sealed mounting cavity inside, within which a lithium battery pack 10 and a controller 11 are compactly arranged. The lithium battery pack 10 is a rechargeable 18650 battery, fixed by a battery bracket. The controller 11 is a printed circuit board integrating a microprocessor, drive circuitry, and protection circuitry. The upper end of the handle 9 has an integrally formed raised protective cavity 7, inside which a control switch assembly 13 is located for user operation.

[0039] The hollow rod 2 adopts a double-layer tube structure to balance lightweight design and internal wiring requirements. It consists of a coaxial cylindrical hollow outer rod and a cylindrical hollow inner rod. The cylindrical hollow inner rod is sleeved inside the cylindrical hollow outer rod, and multiple longitudinal strip ribs are evenly distributed circumferentially between them. These strip ribs connect the inner and outer rods into a whole, while forming a sealed channel for wiring between the inner and outer rods. The power and signal lines of the LED light strip 1 are introduced from the bottom of the strip groove, pass through this channel upwards into the handle 9, and are electrically connected to the corresponding output ports of the controller 11 and the positive and negative terminals of the lithium battery pack 10, respectively.

[0040] By concealing the wires inside the pole, the problems of wear, aging, and visual clutter caused by exposure are avoided; the strip ribs enhance the pole's bending and torsional strength, ensuring that the overall mechanical performance does not decrease after integrating electronic components; the formed sealed channel has a certain degree of moisture protection.

[0041] Furthermore, a sealing end cap 5 is threadedly connected to the upper end of the outer side surface of the protective cavity 7.

[0042] Specifically, a silicone sealing ring is provided on the inner side of the sealing end cap 5. When the sealing end cap 5 is tightened, the sealing ring is deformed under pressure, achieving a tight seal on the upper opening of the protective cavity 7. This effectively prevents rainwater and dust from entering the interior of the protective cavity 7 from above, protecting the contacts and internal circuits of the control switch group 13, and improving the reliability and durability of the product in outdoor humid and dusty environments.

[0043] Furthermore, an anti-slip ring is provided on the outer side of the handle 9, an annular baffle 8 is provided at the lower end of the outer side of the handle 9, and an anti-loss rope 6 is provided at the upper end of the outer side of the handle 9.

[0044] Specifically, the outer surface of the handle 9 is fitted with an anti-slip ring made of silicone to increase friction and prevent slippage caused by sweaty hands. A ring-shaped baffle 8 is fixed to the lower end of the outer surface of the handle 9, which limits and supports the user's hand at the base when gripping, preventing the hand from slipping down and improving comfort and stability during prolonged use. A connecting hole is provided at the upper outer surface of the handle 9 for attaching an anti-loss lanyard 6. The anti-loss lanyard 6 is an elastic wristband that allows the trekking pole to be temporarily strapped to the wrist, preventing accidental drop when temporarily letting go for activities such as taking photos or organizing equipment. This is especially suitable for steep or slippery terrain, increasing safety during use.

[0045] Furthermore, the lower end of the hollow rod 2 is provided with a bottom annular plate 3 and a shock-absorbing rod 4. The shock-absorbing rod 4 is slidably connected to a cylindrical groove provided at the lower end of the hollow rod 2, and a spring 12 is provided at the upper end of the inner side of the cylindrical groove.

[0046] Specifically, a cylindrical groove is machined inside the lowest end of the hollow rod 2. The upper part of the shock absorber 4 slides within this cylindrical groove and can move up and down along its axial direction. A spring 12 is fixed to the upper end of the inner side of the cylindrical groove, and the lower end of the spring 12 rests against the upper end face of the shock absorber 4. The bottom annular plate 3 is fixed to the bottom end of the shock absorber 4.

[0047] When the trekking pole touches the ground, the impact force pushes the shock absorber 4 upward to compress the spring 12. The spring 12 absorbs and buffers most of the impact energy. When the pole leaves the ground, the spring 12 returns to its original position, pushing the shock absorber 4 back to its initial position. This structure effectively reduces the repeated impact on the user's wrists, elbows, and shoulders during long walks or downhill walks, improving comfort and reducing the risk of joint strain.

[0048] Furthermore, the number of the strip grooves is not less than one, and each strip groove is provided with an LED light strip 1 inside.

[0049] Specifically, there are two strip slots, evenly distributed along the circumference of the rod. Each strip slot contains an independent LED light strip 1. The multiple LED light strips 1 are independently controlled by the controller 11.

[0050] By emitting light from multiple directions, blind spots are eliminated, and the trekking poles are clearly visible from any angle, greatly improving the user's visibility and recognition in the environment. At the same time, the overall lighting brightness is increased, which can meet the lighting needs of a wider range. Furthermore, multiple light strips work simultaneously, and if one of them fails, the others can still work, improving the reliability of the system.

[0051] Furthermore, the control switch group 13 includes a mode switching button and a brightness adjustment button. The controller 11 is electrically connected to the LED light strip 1 and is used to control the light emission mode and brightness level of the LED light strip 1. The light emission modes include three types: constant light, flashing, and SOS distress signal.

[0052] Specifically, the control switch group 13 includes a mode switching button and a brightness adjustment button, both of which are waterproof tactile switches. The controller 11 is electrically connected to the LED light strip 1 via wires. Its electrical control principle is as follows: the microprocessor of the controller 11 has pre-stored control programs for multiple light-emitting modes. When the user presses the mode switching button, the microprocessor receives the signal and sequentially switches the output control signals, driving the LED driver circuit to cycle through modes such as "constantly on," "slow flashing," "rapid flashing," and "SOS international distress signal (three short, three long, three short)."

[0053] Pressing the brightness adjustment button activates the microprocessor, which uses PWM technology to adjust the duty cycle of the output current, thereby steplessly or incrementally changing the brightness of the LED strip 1. This provides a high degree of customizability and scene adaptability; constant illumination is used for general lighting, flashing for warnings or team identification, and SOS for emergency calls. Brightness adjustment strikes a balance between power saving and high brightness.

[0054] Furthermore, the protective cavity is provided with a replaceable battery compartment and a USB charging port on its side. The lithium battery pack 10 is connected to an external power source through the USB charging port for charging or powering external devices.

[0055] Specifically, the protective cavity 7 has an opening on its side and a USB charging port is embedded therein. This port is waterproof thanks to a waterproof plug. The charging and discharging management circuit of the lithium battery pack 10 is electrically connected to this USB charging port.

[0056] When an external power source is connected to the USB port via a data cable, the power supply safely charges the lithium battery pack 10 through the charge / discharge management circuit. Furthermore, under the management of the controller 11, this circuit can also reverse the power output from the lithium battery pack 10 via the USB port to provide emergency charging for external devices such as mobile phones and GPS devices. Its advantages lie in greatly enhancing the practicality and battery life of the trekking pole; users do not need to carry extra dedicated chargers and can use it as an outdoor emergency power source, achieving "multi-purpose functionality."

[0057] Example 2, please refer to Figure 7-8 The main difference between this embodiment and embodiment 1 is that the hollow rod 2 in embodiment 1 is non-retractable, while the hollow rod 2 in this embodiment is retractable. Furthermore, the hollow rod 2 includes a rod section 21, a second rod section 22 is sleeved on the inner side of the first rod section 21, and a third rod section 23 is sleeved on the inner side of the second rod section 22. Locking mechanisms 14 are provided at the connection points of the first rod section 21 and the second rod section 22, and at the connection points of the second rod section 22 and the third rod section 23.

[0058] Specifically, the hollow rod 2 is designed as a telescopic structure to adapt to users of different heights and terrain requirements. The first section 21 has the largest diameter, and its inner side is slidably fitted with the second section 22. The inner side of the second section 22 is then slidably fitted with the third section 23. Locking mechanisms 14 are provided at the connection points between the first section 21 and the second section 22, and at the connection points between the second section 22 and the third section 23.

[0059] The strip grooves and internal wiring channels of each pole are electrically connected at the joints by flexible spring wires, ensuring that the power supply and signal of the LED light strip 1 are not interrupted during the extension and retraction process. When retracted, the size is small, making it easy to store and transport; when extended, it can be adjusted to a suitable length to meet different usage scenarios.

[0060] Furthermore, the locking mechanism 14 includes an external threaded sleeve 16, with an internal threaded sleeve 17 threadedly connected to the outer side of the external threaded sleeve 16. The lower end of the outer side of the external threaded sleeve 16 is provided with a plurality of strip grooves 15. The lower end of the outer side of the external threaded sleeve 16 is inverted conical, and the lower end of the inner side of the internal threaded sleeve 17 is positive conical.

[0061] Specifically, the locking mechanism 14 comprises an externally threaded sleeve 16 and an internally threaded sleeve 17. The externally threaded sleeve 16 is fixed to the end of the upper section rod, and its outer surface is machined with external threads. The lower end sidewall of the externally threaded sleeve 16 has multiple axially oriented grooves 15, forming multiple elastic petal-like structures at its lower end, and its lower outer surface is machined into an inverted cone shape. The internally threaded sleeve 17 is rotatably connected to the lower section rod, and its inner surface is machined with internal threads that match the external threads, and its lower inner surface is machined into a positive cone shape.

[0062] When the internal threaded sleeve 17 is rotated to tighten it downwards along the external threaded sleeve 16, the conical surface at the lower end of the internal threaded sleeve 17 presses against the inverted conical surface at the lower end of the external threaded sleeve 16, forcing the petal-shaped structure with the groove 15 to tighten inwards, thus firmly holding the lower section 22 inside and achieving locking and fixation. Reversing the rotation releases pressure, the petal-shaped structure elastically recovers, and the length of the section can be adjusted. It has a large locking force, is easy and reliable to adjust, and is not easily loosened by vibration, ensuring the stability and safety of the trekking pole during use.

[0063] Example 3, please refer to Figure 9 The main difference between this embodiment and embodiment 1 is that the hollow rod 2 in embodiment 1 is non-extendable, while the hollow rod 2 in this embodiment is connected in a multi-section detachable manner. Furthermore, the hollow rod 2 includes a sleeve 24, the lower end face of the sleeve 24 is connected to a second sleeve 25 by a spring pin, and the lower end face of the second sleeve 25 is connected to a third sleeve 26 by a spring pin.

[0064] Specifically, as another embodiment of the retractable structure, the lower inner side of the first sleeve 24 is provided with a spring pin hole, which is connected to the corresponding pin hole on the upper end of the second sleeve 25 via a press-type spring pin. Similarly, the second sleeve 25 and the third sleeve 26 are also connected by a spring pin. During adjustment, pressing the spring pin button allows the inner sleeve to be pulled out or pushed in; releasing the button automatically causes the spring pin to spring into the hole and lock. Its advantages are quick and intuitive operation, accurate positioning, and suitability for scenarios requiring rapid adjustment.

[0065] In use: Hold handle 9, allowing your thumb to naturally reach the control switch group 13 located within the protective cavity 7. A short press of the "mode switch button" sends a command to controller 11, illuminating the LED strip 1. Another short press cycles through the lighting modes: "constant light" for stable illumination, "slow flashing" for warnings or team identification, "rapid flashing" for higher-frequency warnings, and an automatic cycle of three short, three long, three short Morse code light signals for an "SOS distress signal." A long press typically turns off all lights.

[0066] In constant-on mode, pressing the "brightness adjustment button" will cause the controller 11 to adjust the output current via PWM technology, thus changing the brightness of the LED strip 1. Users can choose the most suitable level between power saving and high brightness according to ambient light and personal needs.

[0067] When the lithium battery pack 10 is low on power, use a universal USB charging cable. Connect one end to a standard charger or power bank, and insert the other end into the USB charging port on the side of the protective cavity 7 to charge. It is recommended to pause the use of the lighting function while charging.

[0068] In urgent outdoor situations, this trekking pole can serve as an emergency power source. Connect one end of the USB cable to the trekking pole's USB port and the other end to a mobile phone, GPS device, or similar device. The power management circuitry within the controller 11 will safely output power from the lithium battery pack 10 to charge external devices. It is recommended to use this function when not hiking, and ensure you have sufficient power for lighting on your return trip.

[0069] During walking or hiking, the shock absorption function activates automatically. When the tip of the pole touches the ground, the impact force is transmitted through the bottom annular plate 3 to the shock absorber 4, causing it to compress the internal spring 12 and slide upwards, effectively absorbing and cushioning the impact from the ground. When the pole leaves the ground, the restoring force of the spring 12 pushes the shock absorber 4 back to its original position. Users can continuously enjoy the protection of their hands and joints provided by the shock absorption without any additional operation.

[0070] When gripping, the heel of the palm can rest on the ring-shaped baffle 8 at the lower end of the handle 9, and with the soft anti-slip ring on the handle, a stable grip can be maintained even if the palms are sweaty. When it is necessary to temporarily free the hands, the wrist strap of the anti-loss rope 6 can be put on the wrist to prevent the trekking pole from accidentally slipping off.

[0071] Regularly check that the sealing end cap 5 is tightened to ensure the airtightness of the protective cavity 7 in case of rain or snow. When cleaning, wipe the surface of the rod and LED light strip 1 with a soft cloth, and avoid using corrosive liquids.

[0072] After use, first turn off LED light strip 1.

[0073] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
