Description

A clamping charging device, a cane, and a charging system Technical Field

[0001] This application relates to the field of assistive devices, and more particularly to a clamping charging device, a cane, and a charging system. Background Technology

[0002] In existing technology, a cane is a simple device to assist walking, usually a wooden or metal stick. Canes are an important medical rehabilitation aid, categorized as hand canes, elbow canes, and axillary canes. Hand canes are mainly used for mild needs, such as the elderly or mountaineers, and are not classified as disability aids. Elbow canes are classified as aids for moderate lower limb disabilities. Axillary canes are essential for people with severe lower limb disabilities (illness, injury, etc.), and most people with lower limb disabilities have to use axillary canes for life.

[0003] With the development of technology, canes have evolved from simple sticks into various functions, such as location tracking, fall assistance, trajectory tracking, and electronic fences. As canes become increasingly intelligent, they now require charging to ensure normal use. Most smart canes are charged via USB cables. However, some users are blind or elderly with impaired consciousness. Connecting the charging cable is often difficult for them, or they may not be able to find the cable, preventing the cane from charging and rendering it unusable. This could pose a danger to users when they are out and about due to a dead battery. Summary of the Invention

[0046] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of this application and should not be regarded as undue limitations on this application.

[0047] In the description of the embodiments of this application, the orientations or positional relationships of "up", "down", "left", "right", "front" and "rear" are based on the orientations or positional relationships shown in the accompanying drawings. It should be understood that these orientational terms are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0048] As shown in Figures 1 to 12, a clamping charging device 100 includes: a first fixed base 110, a second fixed base 120, at least two actuating components 140 having a first state and a second state, a locking mechanism, and a charging component 160. The at least two actuating components 140 having the first state and the second state are respectively movably disposed relative to the channel opening 131 of the channel 130.

[0049] The first fixing seat 110 and the second fixing seat 120 can be rectangular or trapezoidal blocks according to design requirements. They can be made of lightweight rigid materials such as plastic, rubber, and aluminum. On the one hand, they can serve as fixing structures for other components, and on the other hand, they are lightweight overall.

[0050] The first fixing seat 110 and the second fixing seat 120 are arranged at an interval to form a channel 130. The width of the channel 130 should be designed to accommodate the diameter of at least a portion of the cane 200 (mentioned below), so that the cane 200 can be placed in the channel 130. In the non-limiting embodiment shown in FIG1, the cane 200 should have an annular stop 220, so that the cane 200 can enter the channel 130 in the horizontal direction, that is, the extension direction of the channel 130, and the stop 220 should cover the first fixing seat 110 and the second fixing seat 120 to prevent the cane 200 from falling in the vertical direction.

[0051] Two actuating components 140 should be movably connected between the fixed base and the rotating base. That is, the two actuating components 140 are respectively movably positioned relative to the channel openings 131 at both ends of the channel 130. In the first state configuration, the actuating components 140 are respectively connected to the first fixed base 110 and the second fixed base 120 to block the corresponding channel openings 131. In the second state configuration, the actuating components 140 avoid the corresponding channel openings 131; it can be understood that in the second state, one of the first fixed base 110 and the second fixed base 120 remains connected to the actuating component 140, while the other of the first fixed base 110 and the second fixed base 120 is separated from the actuating component 140.

[0052] When one of the actuating components 140 is in the second state, the locking mechanism locks the other actuating component 140 in the first state. That is, the locking mechanism locks the other first actuating component 140 to prevent switching from the first state to the second state. The actuating component 140 acts as a connector to the first fixed base 110 and the second fixed base 120 respectively, so that the first fixed base 110 and the second fixed base 120 are connected as a whole, preventing the first fixed base 110 and the second fixed base 120 from completely separating and causing the second fixed base 120 to fall off.

[0053] When one of the actuating components 140 is in the first state, the locking mechanism releases the lock on the other actuating component 140. When both actuating components 140 are in the first state, both actuating components 140 can switch to the second state.

[0054] In the non-limiting embodiments shown in Figures 1 to 4, the cane 200 can be pushed into the channel 130 horizontally from any of the channel openings 131; that is, the user can put the cane 200 into the channel 130 from either end of the channel opening, effectively preventing the user from not being able to find the place to put it.

[0055] The actuating component 140, which was originally blocking the passage 131, avoids the passage 131 and enters the second state. The locking mechanism then locks the other actuating component 140 located at the other end of the passage 131 and keeps it in the first state to prevent the first fixed seat 110 from completely separating from the second fixed seat 120.

[0056] When the cane 200 is placed in the channel 130 from the channel opening 131, the charging component 160 can be used to provide power to the cane 200, realizing intelligent charging of the cane 200 while it is placed.

[0057] Furthermore, the actuating component 140 on the entry channel 131 can return to the first state. Both ends of the channel 131 are closed by the actuating component 140. When the cane 200 is charging in the channel 130, the actuating components 140 blocking the entry channels 131 at both ends limit movement in two directions to prevent the cane 200 from escaping the channel 130. When the user needs to retrieve the cane 200, both actuating components 140 are in the first state, the locking mechanism is released, and both actuating components 140 can switch from the first state to the second state. That is, the cane 200 can be retrieved horizontally from either entry channel 131, rather than requiring it to enter and exit from the same point, greatly facilitating user use and reducing the difficulty of use.

[0058] It should be understood that the users targeted by this application embodiment are blind people or elderly people with impaired consciousness. Therefore, compared with the existing USB ports, which are small and require a USB cable, the cane 200 can be inserted or removed from both sides of the channel 130 in this application embodiment. The larger size of the channel 130 is suitable for users with limited hand and foot mobility to access and insert, thereby greatly reducing the difficulty of using the device. Moreover, there is no need to use a USB port; simply inserting the cane into the channel 130 is sufficient for charging, avoiding situations where users forget to charge or cannot find the charging cable, effectively reducing the difficulty of using a cane that requires charging.

[0059] It should be noted that if there is no separate connection structure between the first fixed base 110 and the second fixed base 120, at least one of the two action components 140 will be in the first state. If there is a separate connection structure to connect the first fixed base 110 and the second fixed base 120 into one unit, the two action components 140 can be in the second state at the same time without affecting the user's use.

[0060] One possible embodiment, as shown in Figures 1 to 7, includes two locking components 151, each of which includes a sensor 152 and a locking element 153 that are linked together.

[0061] In a locking component 151, one of the action components 140 triggers the sensor 152, and the locking component 153 can lock the other action component 140. That is, the sensor 152 of one locking component 151 and the locking component 153 of another locking component 151 are associated with one of the action components 140; the locking component 153 of one locking component 151 and the sensor 152 of another locking component 151 are associated with the other action component 140; thereby realizing the mutual association control between the two action components 140.

[0062] When an action component 140 is in the first state, it triggers the corresponding sensor 152, and the locking component 153 linked to it enters the first action state. When the locking component 153 is in the first working state, it unlocks another action component 140. The other action component 140 corresponding to the locking component 153 can freely switch between the first state and the second state.

[0063] When an action component 140 is in the second state, it triggers the corresponding sensor 152, and the locking component 153 linked to it enters the second working state. When the locking component 153 is in the second working state, it locks another action component 140, preventing it from entering the second state to avoid the corresponding passage 131.

[0064] The locking mechanism and the action component 140 can be configured in various ways and can be flexibly combined.

[0065] In the non-limiting embodiment shown in Figure 5, two actuating components 140 are respectively disposed at both ends of the second fixed base 120. The actuating components 140 can rotate. Both locking components 151 are disposed on the first fixed base 110, wherein the sensing element 152a of the first locking component 151a is disposed at the left end 110a of the first fixed base 110, and the locking element 153a of the first locking component 151a is disposed at the right end 110b of the first fixed base 110.

[0066] Specifically, the left-side actuating component 140 is hinged to the second fixed base 120. Currently, the left-side actuating component 140 is shown in its first state. At least a portion of the actuating component 140 is laterally positioned between the first fixed base 110 and the second fixed base 120, allowing the left-side actuating component 140 to act as a connector between the first fixed base 110 and the second fixed base 120, thus ensuring that they do not separate. The left-side actuating component 140 can trigger the corresponding sensor 152b, which in turn triggers the locking component 153b to enter its first actuating state. In this first working state, the locking component 153b releases the lock on the right-side actuating component 140, allowing the right-side actuating component 140 to freely switch between the first and second states.

[0067] The right-side actuating component 140 is hinged to the second fixed base 120. Currently, the right-side actuating component 140 is in its second state. It rotates clockwise inward by a certain angle to bring it closer to the second fixed base 120, clearing the right-side channel opening 131. This allows the cane 200 to be inserted into the channel 130 from the right side for charging. The right-side actuating component 140 triggers the corresponding sensor 152a, which in turn activates the locking component 153a in its second working state. In this state, the locking component 153a locks the left-side actuating component 140, preventing it from entering the second state to clear the corresponding channel opening 131. This ensures that the left-side actuating component 140 blocks the left-side channel opening 131, preventing the inserted cane 200 from detaching from the channel 130.

[0068] Understandably, when the right-side action component 140 returns to its original position, i.e., in the first state, the locking member 153a releases the lock on the left-side action component 140, so that the left-side action component 140 can freely switch between the first state and the second state, and the cane 200 placed in the channel 130 can be taken out from either end of the channel opening 130 as needed.

[0069] In the non-limiting embodiment illustrated in Figure 6, one actuating component 140 is disposed on the second fixed base 120, and the other actuating component 140 is disposed on the first fixed base 110. The actuating components 140 are rotatable. Of the two locking components 151, the first locking component 151a is disposed on the second fixed base 120, with its sensing element 152a disposed on the right end 120a of the second fixed base 120 and its locking element 153a disposed on the left end 120b of the second fixed base 120; the second locking component 151b is disposed on the first fixed base 110, with its sensing element 152b disposed on the left end 110b of the first fixed base 110 and its locking element 153b disposed on the right end 110b of the first fixed base 110.

[0070] Specifically, the left-side actuating component 140 is hinged to the second fixed base 120. Currently, the left-side actuating component 140 is shown in its first state. At least a portion of the actuating component 140 is laterally positioned between the first fixed base 110 and the second fixed base 120, allowing the left-side actuating component 140 to act as a connector between the first fixed base 110 and the second fixed base 120, thus ensuring that they do not separate. The left-side actuating component 140 can trigger the corresponding sensor 152b, which in turn triggers the locking component 153b to enter its first actuating state. In this first working state, the locking component 153b releases the lock on the right-side actuating component 140, allowing the right-side actuating component 140 to freely switch between the first and second states.

[0071] The right-side actuating component 140 is hinged to the first fixed base 110. Currently, the right-side actuating component 140 is in its second state, rotating counterclockwise inwards by a certain angle to bring it closer to the first fixed base 110, thus avoiding the right-side channel opening 131. This allows the cane 200 to be inserted into the channel 130 from the right side for charging. The right-side actuating component 140 triggers the corresponding sensor 152a, which in turn activates the locking component 153a in its second working state. In this state, the locking component 153a locks the left-side actuating component 140, preventing it from entering the second state to avoid the corresponding channel opening 131. This ensures that the left-side actuating component 140 blocks the corresponding left-side channel opening 131, preventing the inserted cane 200 from detaching from the channel 130 from the left-side channel opening 131.

[0072] Understandably, when the right-side action component 140 returns to its original position, i.e., in the first state, the locking member 153a releases the lock on the left-side action component 140, so that the left-side action component 140 can freely switch between the first state and the second state, and the cane 200 placed in the channel 130 can be taken out from either end of the channel opening 130 as needed.

[0073] In the non-limiting embodiment shown in Figure 7, two actuating components 140 are respectively disposed at both ends of the first fixed base 110. The actuating components 140 can move in a linear reciprocating manner. Of the two locking components 151, the sensor 152a of the first locking component 151a is disposed at the right end 120a of the second fixed base 120, and the locking element 153a of the first locking component 151a is disposed at the left end 110b of the first fixed base 110; the sensor 152b of the second locking component 151b is disposed at the left end 120b of the second fixed base 120, and the locking element 153b of the second locking component 151b is disposed at the right end 110a of the first fixed base 110.

[0074] Specifically, the left-side actuating component 140 is movably mounted on the first fixed base 110 along the width direction of the channel 130. Currently, the left-side actuating component 140 is shown in its first state. At least a portion of the actuating component 140 is laterally positioned between the first fixed base 110 and the second fixed base 120, allowing the left-side actuating component 140 to act as a connector between the first fixed base 110 and the second fixed base 120, thus ensuring that they do not separate. The left-side actuating component 140 can trigger the corresponding sensor 152b, and the linked locking component 153b enters the first actuating state. In this first working state, the locking component 153b releases the lock on the right-side actuating component 140, allowing the right-side actuating component 140 to freely switch between the first and second states.

[0075] The right-side actuating component 140 is movably mounted on the first fixed base 110 along the width direction of the channel 130. Currently, the right-side actuating component 140 is in its second state. This component moves a certain distance along the width direction towards the first fixed base 110, moving away from the second fixed base 120 and clearing the right-side channel opening 131, allowing the cane 200 to be inserted into the channel 130 from the right side for charging. The right-side actuating component 140 triggers the corresponding sensor 152a, which in turn activates the locking component 153a in its second working state. In this second working state, the locking component 153a locks the left-side actuating component 140, preventing it from entering the second state to clear the corresponding channel opening 131. This ensures that the left-side actuating component 140 blocks the corresponding left-side channel opening 131, preventing the inserted cane 200 from detaching from the channel 130 through the left-side channel opening 131.

[0076] Understandably, when the right-side action component 140 returns to its original position, i.e., in the first state, the locking member 153a releases the lock on the left-side action component 140, so that the left-side action component 140 can freely switch between the first state and the second state, and the cane 200 placed in the channel 130 can be taken out from either end of the channel opening 130 as needed.

[0077] It should be noted that in the non-limiting embodiments shown in Figures 5-7, the sensors 152 (152a, 152b) of the locking assembly 151 can be photoelectric sensors, force sensors, or microswitches, etc. The sensors 152 (152a, 152b) emit corresponding signals by sensing the current position of the actuation assembly 140. These signals can be electrical, optical, or pressure signals, etc. The locking elements 153 (153a, 153b) of the locking assembly 151 can be motors, cylinders, or other specific actuating elements. After receiving the signals from the sensors 152 (152a, 152b), the locking elements 153 (153a, 153b) perform corresponding actions to lock or unlock the corresponding actuation assembly 140.

[0078] The locking element 153 and the locking action component 140 come in various forms.

[0079] In the non-limiting embodiments shown in Figures 5-6, the locking member 153 can be directly embedded into the hinge point of the actuating component 140 so that the actuating component 140 cannot rotate relative to the first fixed seat 110 or the second fixed seat 120. Alternatively, it can act directly on the power element (not shown) that drives the actuating component 140. For example, when the power element is a motor or electric motor and the actuating component 140 relies on the power element to move, the locking member 153 can be a switch that can cut off the power supply to the power element, or it can be a block that acts on the power element, etc.

[0080] In the non-limiting embodiment shown in Figure 7, the movement of the actuating component 140 and the first fixed base 110 is a linear reciprocating motion. Specifically, the actuating component 140 has teeth 148 extending in the width direction and is equipped with a motor device 149 with gears. The motor device 149 drives the actuating component 140 to move closer to or away from the second fixed base 120 in the width direction through a gear and rack engagement, thereby achieving the function of closing the passage opening 131 or avoiding the passage opening 131. The locking member 153 can be a switch that can cut off the power to the motor device 149, or a latch that restricts the rotation of the motor device 149, etc.

[0081] In one possible embodiment, the actuation component 140 includes a rotating arm 141 and a reset device 143. The reset device 143 is capable of holding the actuation component 140 in a first state.

[0082] In the non-limiting embodiments shown in Figures 1 to 4 and Figures 8 to 11, the rotating arm 141 may be hinged to the end of the second fixed base 120.

[0083] In the first state of the actuation assembly 140, the rotating arm 141 is arranged laterally between the first fixed seat 110 and the second fixed seat 120 to block the corresponding channel opening 131. In the first state of the actuation assembly 140, the rotating arm 141 is connected to the first fixed seat 110 and the second fixed seat 120 as a connecting member.

[0084] In the second state of the motion assembly 140, the rotating arm 141 is close to the second fixed seat 120 to avoid the corresponding channel opening 131.

[0085] In some other non-limiting embodiments, the rotating arm 141 may also be hinged to the end of the first fixed base 110. When the actuating component 140 is in the second state, the rotating arm 141 is close to the first fixed base 110 to avoid the corresponding channel opening 131.

[0086] Regardless of whether the rotating arm 141 is close to the second fixed base 120 or the first fixed base 110, the maximum angle that the rotating arm 141 can rotate should be sufficient to allow the cane 200 to pass through the space of the passage opening 131 that the rotating arm 141 avoids. In the following embodiments, the rotating arm 141 is described as being hinged to the end of the second fixed base 120.

[0087] In one possible embodiment, as shown in Figures 1 to 4 and Figures 8 to 11, the actuation component 140 includes a pivot 142, a locking lever 144, and a locking spring 146.

[0088] The rotating shaft 142 is hinged to the end of the second fixed seat 120, the reset device 143 is disposed on the rotating shaft 142, and the rotating arm 141 is fixedly connected to the rotating shaft 142.

[0089] The rotating arm 141 has an actuation groove 1411 inside, and the locking rod 144 is coaxially inserted in the actuation groove 1411. That is, the locking rod 144 rotates with the rotation of the rotating arm 141 relative to the second fixed seat 120.

[0090] The locking spring 146 is sleeved on the locking rod 144, and its two ends are respectively connected to the rotating arm 141 and the locking spring 146.

[0091] In the non-limiting embodiments illustrated in Figures 4 and 8, the actuating groove 1411 is a combination of a partial groove and a through hole. The locking spring 146 is a compression spring, with one end abutting against the wall of the actuating groove 1411 and the other end connected to the locking rod 144. The spring force of the locking spring 146 is directed to prevent the locking rod 144 from rotating with the second fixed seat 120.

[0092] One actuating component 140 is in a first state, that is, the rotating arm 141 of the actuating component 140 blocks the corresponding channel opening 131; the rotating arm 141 triggers the corresponding sensor 152, and the locking component 153 linked with it enters the first actuating state. The locking component 153 is in the first working state, which can overcome the elastic force of the locking spring 146 and cause the locking rod 144 of the other actuating component 140 to separate from the second fixed seat 120. The locking rod 144 no longer restricts the end of the rotating shaft 142 from the second fixed seat 120. Due to the relative movement, the rotating arm 141 of another action component 140 switches between the first state and the second state as needed. If the other action component 140 is in the first state, the rotating arm 141 of the action component 140 is connected to the first fixed seat 110 and the second fixed seat 120 as a connector. If the other action component 140 is in the second state, the rotating arm 141 of the action component 140 is close to the second fixed seat 120 to avoid the corresponding channel opening 131, so as to facilitate the insertion or removal of the cane 200.

[0093] One actuation component 140 is in a second state, meaning its rotating arm 141 is close to the second fixed seat 120 to avoid the corresponding channel opening 131. In this state, the cane 200 is inserted into or removed from the channel opening 131. The rotating arm 141 triggers the corresponding sensor 152, and the linked locking component 153 enters a second working state. In this second working state, the locking component 153 no longer provides force to overcome the elasticity of the locking spring 146. Therefore, the locking spring 146 of the other actuation component 140 drives the locking rod 144 to move axially and engage with the second fixed seat 120 to lock it in place. The rotating arm 141 of the actuation component 140 is locked in the first state. The rotating arm 141 acts as a connector, connecting to both the first fixed seat 110 and the second fixed seat 120 to prevent complete separation of the two seats.

[0094] In some other non-limiting embodiments, the actuating groove 1411 may also be an open groove or a closed hole; the locking spring 146 is a tension spring depending on the direction of the applied force. One end of the locking spring 146 is connected to the wall of the actuating groove 1411, and the other end is connected to the locking rod 144. The direction of the elastic force of the locking spring 146 is to separate the locking rod 144 from the second fixing seat 120.

[0095] When one actuation component 140 is in the first state, it triggers the corresponding sensor 152, and the locking component 153 linked to it enters the first actuation state. When the locking component 153 is in the first working state, it no longer provides the force to overcome the elastic force of the locking spring 146. The elastic force of the locking spring 146 causes the locking rod 144 of the other actuation component 140 to separate from the second fixed seat 120. The locking rod 144 no longer restricts the relative movement between the ends of the rotating shaft 142 and the second fixed seat 120. The rotating arm 141 of the other actuation component 140 switches between the first state and the second state as needed.

[0096] When one actuating component 140 is in the second state, it triggers the corresponding sensor 152, and the locking component 153 linked to it enters the second working state. In the second working state, the locking component 153 overcomes the elastic force of the locking spring 146, causing the locking rod 144 of the other actuating component 140 to move axially and engage with the second fixed seat 120 to achieve locking. The rotating arm 141 of the actuating component 140 is locked in the first state. The rotating arm 141, acting as a connector, is connected to both the first fixed seat 110 and the second fixed seat 120 to prevent complete separation of the first fixed seat 110 and the second fixed seat 120.

[0097] In one possible embodiment, as shown in Figures 1 to 4 and Figures 8 to 11, both the sensing element 152 and the locking element 153 are hydraulic cylinders.

[0098] In one locking assembly 151, the cylinders of the sensing element 152 and the locking element 153 are connected to each other. However, the cylinders of the sensing element 152 of one locking assembly 151 and the locking element 153 of another locking assembly 151 are not connected; the two sets of locking assemblies 151 do not affect each other. The sensing element 152 of one locking assembly 151 and the locking element 153 of another locking assembly 151 are arranged on either end of the first fixing base 110.

[0099] The locking assembly 151 includes a fixing block 154 and a fixing spring 155. The fixing block 154 is disposed on the piston rod of the sensing element 152, and the fixing spring 155 is disposed between the fixing block 154 and the cylinder of the sensing element 152.

[0100] In the non-limiting embodiment shown in FIG4, a sensor 152a of a locking assembly 151 is arranged on a first end 110a of a first fixed base 110 for detecting the position of a rotating arm 141 located on one side of the first end 110a; a locking member 153 (not shown in the figure) associated with the sensor 152 is arranged on a second end 110b of the first fixed base 110, and the locking member 153 is capable of locking the relative rotation of the rotating arm 141 located on the second end 110b with the second fixed base 120.

[0101] Similarly, another locking component 151 has a sensor 152 (not shown in the figure) arranged on the second end 110b of the first fixed base 110 for detecting the position of the rotating arm 141 located on the side of the second end 110b. The locking component 153 associated with the sensor 152 is arranged on the first end 110a of the first fixed base 110. The locking component 153 can lock the relative rotation between the rotating arm 141 located on the side of the first end 110a and the second fixed base 120.

[0102] It is important to understand that hydraulic oil is incompressible. The hydraulic oil exists within the sensing element 152 and the locking element 153, and its distribution within these elements is achieved through changes in the volume of their respective cylinders and piston rods. This, in turn, drives the sensing element 152 and the locking element 153 to perform corresponding actions. Because the hydraulic oil distribution occurs within a sealed cavity between the two hydraulic cylinders, there is no need for an external hydraulic pump. Compared to using a photoelectric sensor, force sensor, or microswitch for the sensing element 152, and an electric cylinder for the locking element 153, hydraulic cylinders offer advantages such as fast response, good stability, and ease of maintenance. Furthermore, the clamping charging device 100 is suitable for the charging system, used to hold and charge the cane 200. Since the sensing element 152 and the locking element 153 are hydraulic cylinders, there is no need to separately circuit for them, greatly simplifying the circuit structure of the charging system and reducing the difficulty of use for users.

[0103] When one actuating component 140 is in the first state, the end of the rotating arm 141 away from the rotating shaft 142 abuts against the fixed block 154. Oil is released from the cylinder of the sensing element 152, and the associated locking element 153 enters the first actuating state. Oil is introduced into the cylinder of the locking element 153, causing the piston rod to extend. The extension of the piston rod overcomes the elastic force of the locking spring 146 and drives the locking rod 144 of the other actuating component 140 to move forward. The locking rod 144 then separates from the second fixed seat 120. The actuating component 140 can switch between the first state and the second state, that is, the rotating arm 141 can rotate relative to the second fixed seat 120. In the embodiments of this application, "forward" refers to the direction from the second fixed seat 120 to the first fixed seat 110.

[0104] When one actuating component 140 is in the second state, the end of the rotating arm 141 away from the rotating shaft 142 is separated from the fixed block 154. The fixing spring 155 is a compression spring. After losing the resistance of the rotating arm 141, the fixing spring 155 pushes the piston rod of the sensing element 152 to move outward, thereby driving the cylinder of the sensing element 152 to enter oil. The associated locking component 153 enters the second working state, that is, the cylinder of the locking component 153 exits oil to provide oil for the cylinder of the sensing element 152. The piston rod of the locking component 153 retracts accordingly. The locking spring 146 of the other actuating component 140 can push the locking rod 144 to move backward along the axial direction, thereby causing the locking rod 144 to insert into the second fixed seat 120 to achieve anti-rotation engagement. In the embodiments of this application, "backward" refers to the direction from the first fixed seat 110 to the second fixed seat 120.

[0105] In one possible embodiment, as shown in Figures 1 to 4 and Figures 8 to 11, the end of the rotating arm 141 away from the rotating shaft 142 has an upwardly protruding fixing post 147.

[0106] When one actuating component 140 is in the first state, the fixed post 147 of the actuating component 140 abuts against the fixed block 154, the cylinder of the sensing element 152 releases oil, and the associated locking element 153 enters the first actuating state. The cylinder of the locking element 153 releases oil, causing the piston rod to extend. The extension of the piston rod can overcome the elastic force of the locking spring 146 and drive the locking rod 144 of the other actuating component 140 to move forward. The locking rod 144 then separates from the second fixed seat 120. The actuating component 140 can switch between the first state and the second state, that is, the rotating arm 141 can rotate relative to the second fixed seat 120.

[0107] When one actuating component 140 is in the second state, the fixing post 147 of the actuating component 140 is separated from the fixing block 154. The fixing spring 155 is a compression spring. After losing the resistance of the fixing post 147, the fixing spring 155 pushes the piston rod of the sensing element 152 to move outward, thereby driving the cylinder of the sensing element 152 to enter oil. The locking element 153 associated with the sensing element 152 enters the second working state, that is, the cylinder of the locking element 153 exits oil to provide oil to the cylinder of the sensing element 152, causing the piston rod of the locking element 153 to retract accordingly. The locking spring 146 of the other actuating component 140 can push the locking rod 144 to move backward along the axial direction, thereby causing the locking rod 144 to be inserted into the second fixing seat 120 to achieve anti-rotation engagement.

[0108] In one possible embodiment, as shown in Figures 1 to 4 and Figures 8 to 11, a rotating groove 112 is formed on the lower bottom surface 111 of the first fixed base 110. The fixing post 147 of the actuating component 140 moves in the corresponding rotating groove 112. Typically, there is one actuating component 140 at each end of the first fixed base 110; therefore, there is also one corresponding rotating groove 112 on each side of the lower bottom surface 111. The center of the rotating groove 112 should coincide with the rotation center of the rotating arm 141 to avoid interference between the fixing post 147 and the rotating groove 112 during the movement of the rotating arm 141.

[0109] In one possible embodiment, as shown in Figures 1 to 4 and Figures 8 to 11, the locking assembly 151 includes a locking block 156 disposed on the piston rod of the locking member 153; the locking block 156 may be L-shaped.

[0110] The actuation component 140 includes a locking post 145, which is vertically disposed at the end of the locking lever 144 away from the pivot 142, and the locking block 156 overlaps with the locking post 145.

[0111] When an action component 140 is in the first state, it triggers the corresponding sensor 152, and the locking component 153 linked with it enters the first action state. When the locking component 153 is in the first working state, the locking component 153 can move the locking pin 145 of another action component 140 forward through the locking block 156, thereby driving the locking rod 144 to move away from the rotating shaft 142 to separate the locking rod 144 from the second fixed seat 120.

[0112] When one actuation component 140 is in the second state, it triggers the corresponding sensor 152, and the locking component 153 linked to it enters the second working state. When the locking component 153 is in the second working state, the piston rod of the locking component 153 retracts, causing the locking block 156 to retract to provide space for the locking pin 145 of the other actuation component 140 to move. The locking spring 146 of the other actuation component 140 drives the locking rod 144 to move axially backward and engage with the second fixed seat 120 to prevent rotation.

[0113] In one possible embodiment, as shown in Figures 1 to 4 and Figures 8 to 11, the lower bottom surface 111 of the first fixed base 110 has an arc-shaped groove 113. The locking pin 145 of the actuating component 140 moves in the corresponding rotating groove 112. Typically, there is one actuating component 140 at each end of the first fixed base 110; therefore, there is also one corresponding arc-shaped groove 113 on each side of the lower bottom surface 111. The center of the arc-shaped groove 113 should coincide with the rotation center of the rotating arm 141 to avoid interference between the locking pin 145 and the rotating groove 112 during the movement of the rotating arm 141.

[0114] Furthermore, as the locking lever 144 separates from or approaches the second fixed seat 120, the locking pin 145 will also undergo a certain degree of positional change forward or backward. Therefore, the width of the arc groove 113 should be sufficient to accommodate the locking pin 145.

[0115] In one possible embodiment, as shown in Figures 1 to 4 and Figures 8 to 11, the second fixing base 120 has a receiving groove 123 for accommodating the locking post 145 and the fixing post 147. The receiving groove 123 allows the rotating arm to be fixed and pressed into the receiving groove by the cane when rotating inward, so that the rotating arm 141 can be flush with the second fixing base 120, thereby maximizing the width of the cane 200 when entering the channel 130.

[0116] One possible embodiment, as shown in Figures 1 to 4 and Figures 8 to 11, is that the reset device 143 includes a reset spring 1431, a reset part 1432, and a reset block 1433.

[0117] The reset part 1432 is fixed on the rotating shaft 142, and the reset block 1433 is circumferentially fixedly sleeved on the rotating shaft 142, so that the reset block 1433 can only move along the axis of the rotating shaft 142 and cannot rotate relative to it. The opposite end faces of the reset part 1432 and the reset block 1433 are adapted to each other. The reset spring 1431 is provided at the upper end of the reset block 1433. The reset spring 1431 is a compression spring or a tension spring, so that the reset block 1433 always has a downward pressure.

[0118] In the non-limiting embodiment shown in Figure 4, the top surface of the reset part 1432 is a concave surface with an arc, and the bottom surface of the reset block 1433 is a convex surface with an arc. The two surfaces match each other so that when the convex and concave surfaces are fully engaged, the circumferential relative position of the reset part 1432 and the reset block 1433 is fixed. When the convex and concave surfaces are not fully engaged, the vertical force applied by the reset spring 1431 can convert the reset part 1432 and the reset block 1433 into a circumferential rotational force, allowing them to return to a specific circumferential relative position. Through proper design, when the convex and concave surfaces are fully engaged, the first fixed seat 110 and the second fixed seat 120 are positioned laterally opposite the rotating arm 141 of the actuation assembly 140.

[0119] A cylinder 121 coaxially arranged with the rotating shaft 142 is formed on the second fixed seat 120. A locking groove 122 is formed on the side wall of the cylinder 121. The locking groove 122 can be an open groove or a recess.

[0120] The locking lever 144 can be pulled out or inserted into the locking groove 122 under the action of the locking spring 146 or the locking element 153.

[0121] When one actuating component 140 is in the first state, the fixed post 147 of the actuating component 140 abuts against the fixed block 154, the cylinder of the sensing element 152 releases oil, and the associated locking element 153 enters the first actuating state. The cylinder of the locking element 153 releases oil, causing the piston rod to extend. The extension of the piston rod can overcome the elastic force of the locking spring 146 and drive the locking rod 144 of the other actuating component 140 to move forward. The locking rod 144 is pulled out of the locking groove 122, and the circumferential restriction on the rotating arm 141 is removed. The rotating arm 141 can rotate relative to the second fixed seat 131. The other actuating component 140 can switch between the first state and the second state.

[0122] When one actuating component 140 is in the second state, the fixing post 147 of the actuating component 140 is separated from the fixing block 154. The fixing spring 155 is a compression spring. After losing the resistance of the fixing post 147, the fixing spring 155 pushes the piston rod of the sensing element 152 to move outward, thereby driving the cylinder of the sensing element 152 to enter oil. The locking element 153 associated with the sensing element 152 enters the second working state, that is, the cylinder of the locking element 153 exits oil to provide oil to the cylinder of the sensing element 152, causing the piston rod of the locking element 153 to retract accordingly. The locking spring 146 of the other actuating component 140 can push the locking rod 144 to move backward along the axial direction, thereby causing the locking rod 144 to be pulled out of the locking groove 122 to achieve anti-rotation engagement.

[0123] In one possible embodiment, as shown in Figures 1 to 4 and Figures 8 to 11, the reset device 143 includes a limiting plate 1434 fixedly connected to the second fixed seat 120. A vertical groove 1435 is provided on the side of the reset block 1433 along the axial vertical direction. The limiting plate 1434 is embedded in the vertical groove 1435, so that the reset block 1433 and the rotating shaft 142 are circumferentially fixed, so that the reset block 1433 can only move vertically up and down along the axial direction and will not move circumferentially.

[0124] This document also provides a cane 200, which is used in the aforementioned clamping charging device 100. The cane 200 includes charging electrodes 210 for cooperating with the charging assembly 160.

[0125] In the non-limiting embodiments shown in Figures 1 to 4 and Figures 8 to 11, the charging assembly 160 includes a charging interface 162 and a guide post 161. The guide post 161 is electrically connected to the charging interface 162 and is used to obtain electrical energy from the outside and transmit it to the charging interface 162.

[0126] The charging electrode 210 is a metal strip located on the outer circumference of the cane 100. It can be a long arc, either annular or nearly annular. Typically, there are two charging electrodes 210, spaced apart, serving as the positive and negative terminals for charging, respectively. The charging interface 162 is a metal strip or sheet, which can be linear. Typically, there are two charging interfaces 162, spaced apart, serving as the positive and negative terminals for charging, respectively. The charging interface 162 is located on the side of the first fixing base 100 facing the second fixing base 120.

[0127] When the cane 200 is placed in the channel 130, the charging interface 162 makes contact with the charging electrode 210, and the charging interface 162 provides power to the cane 200. The cane 200 can thus provide various functions such as location tracking, fall rescue, trajectory query and electronic fence, and finally realize intelligent charging of the cane 200 while it is placed.

[0128] In some other non-limiting embodiments, the charging interface 162 may also be disposed on the side of the second mounting base 120 facing the first mounting base 100.

[0129] This document provides another charging system, as shown in Figures 1 to 4 and Figures 8 to 17, comprising: a track assembly 310 for mounting on a wall, a clamping charging device 100 as described in the above embodiments, and a connecting assembly 330 that moves along the track assembly 310 and is connected to a first fixed base 110.

[0130] The clamping charging device 100 enables intelligent charging of the cane 200 while it is placed, reducing the difficulty for users in charging the cane 200. The connecting component 330 moves along the track component 310, allowing the clamping charging device 100 to adjust its position at any time according to the pre-laid track component 310, making it convenient for users.

[0131] It's important to understand that existing smart canes have charging ports on their side. Charging requires inserting the charging head into these ports. While this is simple for able-bodied people, it's extremely difficult for elderly or blind individuals with impaired consciousness. They need to find the charger in the room and insert it into the cane. Finding and recognizing the charger is already strenuous; inserting it into the charging port is even more difficult if their hands are trembling or they can't see. Even if they do manage to charge, due to memory decline, they may easily forget where the cane is currently charging, requiring them to search for it when going out, which is extremely inconvenient and could lead to the risk of going out without a cane because they can't find it charging.

[0132] One possible embodiment, as shown in Figures 1 to 4 and Figures 8 to 17, includes a charging system comprising a motion control component 340 and a stationary component 350.

[0133] The motion control component is configured to drive the connecting component 330 to move along the track component 310; the stationary component 350 is configured to send a signal to the motion control component 340 to drive the connecting component 330 to move to a designated position.

[0134] The designated location here refers to the position obtained by the fixed-point component 350 after calculation based on the signals emitted by the user during use. The signals emitted by the user can be physical touch or photoelectric signals.

[0135] In this embodiment, the user only needs to send a signal to the fixed-point component 350, for example, by touching the movable fixed-point component 350 with their hand or a cane. The fixed-point component 350 then transmits position information to the movement control component 340. After receiving the position information transmitted by the fixed-point component 350, the movement control component 340 drives the connecting component 330 to move along the track component 310, thereby moving the clamping charging device 100 to the designated position. The user can then conveniently place the cane 200 to be charged into the channel 130 of the clamping charging device 100 for charging; or conveniently remove the fully charged cane 200 from the channel 131, avoiding the user having to search for the clamping charging device 100 and providing ease of use.

[0136] In one possible embodiment, as shown in Figures 1 to 4 and Figures 8 to 17, the connecting assembly 330 includes a first body 331, a second body 332, a connector 333, two connecting rods 334, and a plurality of rollers 335.

[0137] Along the horizontal direction of the movement of the connecting assembly 330 in the track assembly 310, the first body 331 and the second body 332 are respectively hinged to both sides of the connecting member 333.

[0138] Along a vertical direction perpendicular to the horizontal direction, multiple rollers 335 are disposed at the top and bottom ends of the first body 331 and the second body 332. In the non-limiting embodiment shown in FIG11, one roller 335 is disposed at the top and bottom ends of the first body 331 and the second body 332. In some other non-limiting embodiments, multiple rollers 335 may be disposed at the top and bottom ends of the first body 331 and the second body 332.

[0139] The track assembly 310 includes a fixing plate 311 for fixing to a wall and a track 312 fixed to the fixing plate 311; the track 312 has a guide groove 3121 through which the first body 331, the second body 332 and the roller 335 pass. The track 312 includes a straight track section 3122 and an arc track section 3123.

[0140] The connecting component 330 is matched with the guide rail groove 3121 of the corresponding shape. The guide rail groove 3121 has a matching groove 3121a for accommodating the roller 335. The two are in rolling contact, which makes the friction of the connecting component 330 moving with the track 312 small and the movement smooth.

[0141] One end of each of the two connecting rods 334 is hinged to the bottom end of the first body 331 and the second body 332, respectively, and the other end of the connecting rods 334 is hinged to the top surface 114 of the first fixed seat 110.

[0142] In the non-limiting embodiment shown in Figure 11, the two connecting rods 334 are not parallel. Instead, the ends of the connecting rods 334 that are close to the top surface 114 are close to each other, while the ends of the connecting rods 334 that are close to the first body 331 and the second body 332 are far apart, forming a trapezoidal shape. The trapezoidal shape provides a certain degree of stability, ensuring the stability of both ends of the connecting rods 334 when the connecting assembly 330 drives the clamping charging device 100 to move linearly along the straight track section 3122. When the connecting assembly 330 enters the arc track section 3123, the connecting assembly 330 changes shape with the track 312. The distance between the connection points of the two connecting rods 334 and the connecting assembly 330 also adjusts the angle as the connecting assembly 330 changes, thereby ensuring that the connecting assembly 330 passes smoothly through the arc track section 3123.

[0143] In one possible embodiment, as shown in Figures 1 to 4 and Figures 8 to 17, the motion control component 340 includes a control module 341 and a servo motor 342. The control module 341 controls the servo motor 342.

[0144] The positioning component 350 includes a resistance wire 351 and a conductive sheet 352 spaced apart from the resistance wire 351. Both the resistance wire 351 and the conductive sheet 352 are arranged along the extension direction of the track component 310. The resistance wire 351 and the conductive sheet 352 can form a loop when short-circuited. The control module 341 can confirm the designated position based on the current in the loop and control the rotation of the servo motor 342.

[0145] By passing a small current through the resistance wire 351, when the user presses the protective cover 353 at the upper end of the resistance wire 351, the resistance wire 351 can make contact with the conductive plate 352. The conductive plate 352 transmits the current magnitude at the contact point to the control module 341. The control module 341 can test the current magnitude, calculate the contact position between the resistance wire 351 and the conductive plate 352 based on the current magnitude, and control the servo motor 342 to drive the connecting assembly 330 to move to that position, thereby driving the clamping charging device 100 to the designated position. The user can then conveniently place the cane 200 to be charged into the channel 130 of the clamping charging device 100 for charging.

[0146] When the cane 200 needs to be retrieved, the user only needs to touch any point on the protective cover 353 at the upper end of the resistance wire 351 of the positioning component 350. Then, the servo motor 342 drives the connecting component 330 to move to that position, thereby bringing the clamping charging device 100 containing the cane 200 to this position. The fully charged cane 200 can then be taken out, avoiding the need for the user to search for the clamping charging device 100 and providing convenience.

[0147] In one possible embodiment, as shown in Figures 1 to 4 and Figures 8 to 17, the movement control assembly 340 includes a drive wire rope 343 arranged along the extension direction of the track assembly 310. The drive wire rope 343 passes through a guide rail groove 3121.

[0148] The servo motor 342 is located at one end of the track assembly 310, and the other end of the track assembly 310 is provided with a fixed pulley 344. The transmission steel wire rope 343 passes around the fixed pulley 344 and its two ends are respectively connected to the first body 331 and the second body 332 to form a loop. The servo motor 342 is connected to the transmission steel wire rope 343 for transmission.

[0149] Specifically, when using the charging system provided in this application, the user can touch the positioning component 350 with their hand or a cane. By pressing the protective cover 353 at the upper end of the resistance wire 351, the resistance wire 351 comes into contact with the conductive sheet 352. The conductive sheet 352 transmits the current at the contact point to the control module 341. The control module 341 can test the magnitude of the current and calculate the position of the contact between the resistance wire 351 and the conductive sheet 352 based on the magnitude of the current. Thus, the positioning component 350 transmits position information to the movement control component 340, and the movement control component 340 receives the position information transmitted from the positioning component 350.

[0150] The servo motor 342 drives the transmission wire rope 343 to rotate along the straight rail section 3122 and the arc rail section 3123. At the same time, the connecting component 330 connected to the transmission wire rope 343 moves with the rotation of the transmission wire rope 343, thereby driving the clamping charging device 100 connected to the connecting component 330 to move towards the user's touch point, and stops moving after approaching the user's touch position. The user can directly press the cane 200 to be charged into one of the channels 131 of the clamping charging device 100. The main body of the cane 200 contacts the rotating arm 141 on one side of the clamping charging device 100, squeezing the rotating arm 141 in the first state, causing the rotating arm 141 to rotate along the rotation axis, thereby clearing the channel 131. At this time, the rotating arm 141 is in the second state. After the rotating arm 141 completely clears the channel 131, the cane 200 enters the channel 130 of the clamping charging device 100. Then, the reset device 143 drives the rotating arm 141 to automatically return to the first state. In the channel 130, the charging electrode 210 of the cane 200 contacts the charging interface 162 on the side of the first fixed base 100 facing the second fixed base 120 to establish an electrical connection, and the cane 200 can then be charged.

[0151] When the cane 200 needs to be retrieved, the user does not need to go to the current storage location of the cane 200. They only need to touch any point on the protective cover 353 at the upper end of the resistance wire 351 of the nearest fixed component 350. The servo motor 342 drives the connecting component 330 to move to that position, thereby moving the clamping charging mechanism 100 to the vicinity of the user's touch position. The user can directly squeeze the rotating arm 141 at any end of the clamping charging device 100 to take out the charged cane 200, avoiding the user having to search for the clamping charging device 100 and providing convenience.

[0152] In one possible embodiment, as shown in Figures 1 to 4 and Figures 8 to 17, the positioning assembly 350 includes an insulating fixing block 354 disposed on a fixing plate 311, and a resistance wire 351 passing through the insulating fixing block 354. The track assembly 310 includes an outer cover 313 covering the track 312 to prevent dust.

[0153] One possible embodiment, as shown in Figures 1 to 4 and Figures 8 to 17, is that the track 312 includes a plurality of support components 3124 arranged on the arc track segment 3123.

[0154] The support assembly 3124 includes a pulley bracket 3125, a support pulley 3126 mounted on the pulley bracket 3125, a limiting rod 3127 movably supported at the lower end of the pulley bracket 3125, a rotating rod 3128, and a return spring 3129 sleeved on the limiting rod 3127. The rotating rod 3128 is hinged to one end of the pulley bracket 3125, and a limiting groove 314 is formed on the arc track section 3123 to cooperate with the rotating rod 3128. The rotating rod 3128 can press the pulley bracket 3125 closer to or away from the arc track section 3123. The track 312 may also include multiple small pulleys 315 arranged on the arc track section 3123. The small pulleys 315 are arranged at intervals relative to the support assembly 3124, and the small pulleys 315 are used to support the section of the annular transmission steel wire rope 343 away from the connecting assembly 330.

[0155] The end of the rotating rod 3128 engages with the limiting groove 314 via a cylinder. Rotating the rotating rod 3128 causes the cylinder to press against the upper surface of the limiting groove 314, thereby pressing the return spring 3129 to move axially downwards. This causes the pulley bracket 3125 to approach the arc track section 3123. When the connecting assembly 330 passes through the arc track section 3123, the front inclined surface 331a of the first main body 331 presses against the rotating rod 3128, causing the support pulley 3126 to move downwards as a whole, that is, to approach the arc track section 3123. This allows the connecting assembly 330 to smoothly pass through the contact position with the support pulley 3126, ensuring the feeding progress and accuracy of the transmission wire rope 343 when the connecting assembly 330 passes through the support pulley 3126.
