Description

Technical Field

[0001] This invention relates to an assistive walking device, specifically a walking stick. Background Technology

[0002] A walking stick is a commonly used assistive walking device. It is often used to help the elderly and people with mobility impairments with daily walking or as an assistive tool for outdoor activities.

[0003] In scenarios involving the use of walking sticks, users often experience accidents due to their own actions or external environmental influences. Because of the suddenness of these events, and often because the person involved is unable to recall the specific circumstances after the accident due to injury, it is difficult to reconstruct the events leading up to and following the accident in a complete manner, hindering further investigation and evidence gathering regarding the cause of the accident. Summary of the Invention

[0004] In view of this, embodiments of this application aim to provide a walking stick capable of recording information about the features of the surrounding environment.

The adapter is connected to the output element, the elastic energy storage element is connected between the adapter and the rotating element, the rotating element is fixedly connected to the second rod, and the braking element is fixed in the circumferential direction along the first rod. The adapter rotates relative to the rotating element under the drive of the output element to allow the elastic energy storage element to store elastic potential energy.

The push block can move along the axial direction of the second cane towards the connection position between the mounting rod and the second cane body under the drive of the spring.

[0025] In some embodiments, the cane includes an unlocking device that can be triggered by a drive device to actuate the release component when the cane is in a collapsed state, thereby switching the extension component from the locked state to the released state.

[0026] In some embodiments, the cane includes an unlocking device comprising a first guide, a second guide, a trigger, and an unlocking member. The second cane includes a second cane body, a release assembly, and an extension assembly. The extension assembly is movably disposed on a lateral side of the second cane body. The camera device is disposed on the extension assembly. The extension assembly includes a locked state attached to the surface of the second cane body and a released state extending from a lateral side of the second cane body. The second cane body is coaxially connected to the braking member. The first guide, when the cane is in a collapsed state, guides the braking member to move axially along the first cane, causing the elastic braking block to disengage from the braking slot axially along the first cane. The second guide, when the cane is in a collapsed state, guides the trigger to move axially along the second cane. The unlocking member is disposed on the second cane body. The second guide and the unlocking member can abut against each other to trigger the unlocking member to drive the release assembly, causing the extension assembly to switch from the locked state to the released state, and driving the camera device to move in a direction away from the rotation axis of the second cane.

[0027] In some embodiments, the braking member is provided with a first annular portion, the first annular portion extending axially along the first rod, the side wall of the first annular portion facing the axis of the first rod being a first guide inner wall, the distance from the end of the first guide inner wall near the brake slot to the axis of the first rod being a first spacing, the distance from the end of the first guide inner wall away from the brake slot to the axis of the first rod being a second spacing, the first spacing being greater than the second spacing, the first guide member being a first guide ring, the first guide ring being provided with a first guide slope, the extension direction of the first guide slope being the same as the extension direction of the first guide inner wall, and the two being in contact, the position of the first guide member relative to the first rod being fixed, and the first guide member being located on the side of the braking member near the first rod.

[0028] In some embodiments, the second guide member is provided with a second annular portion extending along the axial direction of the second staff. The side wall of the second annular portion opposite to the axis of the second staff is a first guide outer wall. The distance from the end of the first guide outer wall away from the brake member to the axis of the second staff is a third spacing, and the distance from the end of the first guide outer wall near the brake member to the axis of the second staff is a fourth spacing. The third spacing is greater than the fourth spacing. The trigger member is a guide ring, and a portion of the second staff passes through the guide ring. The guide ring is provided with a second guide inclined surface. The extension direction of the second guide inclined surface is the same as the extension direction of the first guide outer wall, and the two are in contact. The position of the second guide member relative to the first staff is fixed, and the second guide member is located on the side of the trigger member away from the first staff.

[0029] In some embodiments, the guide ring has a plurality of trigger grooves radially formed on the inner wall facing the second rod. The trigger grooves are arranged at equal intervals along the circumference of the guide ring, and the trigger grooves open along the axial direction of the second rod towards the brake member to form a trigger port. The unlocking member includes an unlocking block and an unlocking cylinder. A portion of the unlocking block can pass through the trigger port along the axial direction of the second rod and enter the trigger groove, and can abut against the inner wall of the trigger groove. The unlocking block is rotatably connected to the second rod, and the side of the unlocking block away from abutting against the inner wall of the trigger groove abuts against the end of the telescopic rod of the unlocking cylinder.

[0030] In some embodiments, the release assembly includes a release block and a release cylinder, the rodless chamber of the release cylinder is connected to the rodless chamber of the unlocking cylinder, the end of the telescopic rod of the release cylinder abuts against the release block, the release block is movably connected to the second rod body, and the release block can drive the extension assembly to switch from the locked state to the released state.

[0031] In this embodiment of the invention, the cane uses a camera device to perceive the surrounding environment and record and store it or upload it remotely. After an accident occurs, the surrounding environment data recorded by the camera device can be used to reconstruct the scene of the accident, which is convenient for determining the cause of the accident and the responsible party afterward.

[0032] The camera device rotates around the circumference of the cane, allowing it to obtain a wider field of view and collect more environmental data, thus further improving the accuracy of accident scene reconstruction.

[0033] By using a drive mechanism to generate energy from the shaking of the cane to drive the rotation of the camera device, the need for an external power source to drive the rotation of the camera device is avoided, reducing overall power consumption. Under the premise of a certain total stored energy, more energy can be concentrated to supply the camera device, thereby increasing the camera device's endurance and further improving the camera device's ability to continuously collect data from the surrounding environment, reducing the probability of the camera device losing power in the event of an accident.

[0051] 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 the purpose of this application and should not be regarded as undue limitations on this application.

[0052] In the description of this application, the "axial" orientation or positional relationship is based on the appendix. Figure 1The orientations or positional relationships shown are intended 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, and therefore should not be construed as a limitation of this application.

[0053] This invention provides a walking stick, see below. Figure 1 and Figure 2 The walking stick includes a stick body (not shown in the figure), a camera device 40, and a drive device 10. The stick body is provided with a grip part 31. The camera device 40 is disposed on the stick body. The drive device 10 is disposed on the stick body and includes a pendulum 11, a conversion component 12, and an energy storage component 13. The pendulum 11 can swing under the shaking of the stick body. The conversion component 12 drives the energy storage component 13 under the action of the pendulum to store energy that can cause the camera device 40 to rotate circumferentially along the stick body.

[0054] In this embodiment of the invention, the cane uses a camera device 40 to perceive the surrounding environment and record and store it or upload it remotely. After an accident occurs, the surrounding environment data recorded by the camera device 40 can be used to reconstruct the scene of the accident, which is convenient for determining the cause of the accident and the responsible party afterward.

[0055] The camera device 40 rotates around the circumference of the cane, which allows the camera device 40 to obtain a wider field of view, making it easier for the camera device 40 to collect richer environmental data and further improving the accuracy of accident scene reconstruction.

[0056] The drive device 10 uses the energy generated by the shaking of the cane to drive the rotation of the camera device 40, avoiding the need for an external power source to drive the rotation of the camera device 40, reducing the overall power consumption. Under the premise of a certain total stored energy, more energy can be concentrated and supplied to the camera device 40, thereby increasing the endurance of the camera device 40, further improving the ability of the camera device 40 to continuously collect data on the surrounding environment, and reducing the probability of the camera device 40 losing power in the event of an accident.

[0057] It is understandable that the hardware and software technologies involved in the camera device 40 for recording, storage, and communication have mature solutions in the existing technology, and will not be elaborated further here.

[0058] It is understandable that the specific form of energy stored in the energy storage component 13 is not limited.

[0059] For example, the pendulum 11 works in conjunction with the electromagnetic coil to generate current through electromagnetic induction during the swing of the pendulum 11, and stores the current in a rechargeable battery. The battery discharge then drives the motor to rotate the camera device 40.

[0060] For example, the conversion component 12 drives the energy storage component 13 to store elastic potential energy under the action of the pendulum. The energy storage component 13, under the action of its own elastic potential energy, drives the camera device 40 to rotate around the circumference of the rod. Elastic potential energy can be stored and released using a flexible mechanical structure. Compared with storing and releasing electrical energy, the process of generating and releasing elastic potential energy and the required structure are simpler, making the structure of the energy storage component 13 more compact and reducing costs.

[0061] Understandably, the rotation method of the camera device 40 should facilitate the camera device 40 in obtaining clear environmental data.

[0062] Specifically, in some embodiments, the camera device 40 rotates intermittently along the circumference of the cane in the same direction, with each interval involving the same angle of rotation. This consistent rotation in the same direction allows the camera device 40 to collect environmental data from all directions, reducing the likelihood of missing crucial environmental data during an accident. The camera device 40 collects environmental data during the intervals between rotations; since its position is relatively stable during these intervals, the probability of data distortion caused by the cane's rotation is reduced, thus improving the accuracy of accident scene reconstruction.

[0063] In some embodiments, see Figure 1 and Figure 2 The cane includes a first cane 30 and a second cane 20. The first end of the first cane 30 has a grip 31, and the second cane 20 is located at the second end of the first cane 30. A drive device 10 is connected between the first cane 30 and the second cane 20. A camera device 40 is mounted on the second cane 20. A pendulum 11 can swing under the swaying of the first cane 30, and an energy storage component 13 drives the second cane 20 to rotate circumferentially under the action of its stored energy. The first cane 30 is used for the user to grip, and the second cane 20 provides mounting space for the camera device 40, allowing it sufficient space to rotate.

[0064] In some embodiments, see Figure 1 and Figure 2 The cane includes a limiting housing 60, within which a protective cavity (not shown in the figure) is formed, and the drive device 10 is disposed within the protective cavity. The limiting housing 60 can prevent external debris from entering the drive device 10, reducing the probability of affecting the normal operation of the drive device 10.

[0065] Understandably, due to the complex and varied environments in which the cane is used, the pendulum 11 often swings randomly. Therefore, the swing direction of the pendulum 11 can be restricted so that the conversion component 12 can better convert the kinetic energy of the pendulum 11's swing. For example, see [reference needed]. Figure 2The conversion assembly 12 includes a swing shaft (not shown in the figure), which passes through the end of the pendulum 11 away from the center of mass, and the extension direction of the swing shaft is parallel to the axial direction of the first rod 30. This allows the pendulum 11 to rotate only around the circumference of the first rod 30.

[0066] It is understandable that the conversion component 12 should have the ability to collect the potential energy generated by the pendulum 11 under different swing directions.

[0067] In some embodiments, see Figure 3 The conversion component 12 includes an input component 121, a first steering assembly 122, a second steering assembly 123, and an output component 124. The input component 121, under the action of the pendulum 11, drives the first steering assembly 122 and the second steering assembly 123 to rotate. Both the first and second steering assemblies 122 and 123 can drive the output component 124 to rotate in the same direction. The output component 124 is connected to the energy storage component 13. The pendulum 11 can rotate in two different directions around the circumference of the first rod 30. The first and second steering assemblies 122 and 123 are each driven by the rotating pendulum 11 in one direction, ensuring that the kinetic energy generated by the rotation of the pendulum 11 can be converted, thus improving the conversion efficiency of the conversion component 12 in terms of the pendulum 11's kinetic energy. The output component 124 always rotates in one direction, reducing the difficulty for the energy storage component 13 to receive the kinetic energy transmitted by the output component 124 and improving the energy storage efficiency.

[0068] Understandably, the transmission of the various components within the conversion assembly 12 should employ a highly efficient transmission method to reduce energy loss and improve energy utilization. For example, gear transmission could be used.

[0069] Specifically, in some embodiments, see [reference] Figure 3 and Figure 4 The input component 121 is an input gear, which is fixedly connected to the pendulum 11. The rotation axis of the input gear is collinear with the swing axis of the pendulum 11. The input gear can rotate directly with the pendulum 11 in two different directions along the circumference of the first rod 30, and drive the first steering assembly 122 and the second steering assembly 123 to rotate in a gear meshing transmission manner, thereby reducing energy transmission loss.

[0070] In some embodiments, see Figure 3The first steering assembly 122 includes a first transmission gear 1221, a first one-way transmission member 1222, and a first steering gear 1223. The first transmission gear 1221 meshes with the input gear. The first one-way transmission member 1222 is connected between the first transmission gear 1221 and the first steering gear 1223. The first transmission gear 1221 and the first one-way transmission member 1222 are in a one-way transmission engagement so that the first one-way transmission member 1222 drives the first steering gear 1223 to rotate in one direction. The output member 124 is an output gear, and the first steering gear 1223 meshes with the output gear.

[0071] The first transmission gear 1221 can rotate in different directions with the input gear. Under the conversion of the first unidirectional transmission member 1222, the first steering gear 1223 can always rotate in the same direction, thereby driving the output gear to rotate only in the same direction. On the one hand, the energy storage component 13 does not need to adapt to the rotation of the output gear in two different directions at the same time, which reduces the structural complexity of the energy storage component 13. On the other hand, it avoids the release of the elastic potential energy stored in the energy storage component 13 due to the reverse rotation of the output gear, so that the rotation of the output gear can always drive the energy storage component 13 to store elastic potential energy, thereby improving the conversion efficiency.

[0072] In some embodiments, see Figure 4 , Figure 5 and Figure 7 The first one-way transmission component 1222 includes a first shaft 1222b and a first transmission pawl 1222a. A first transmission ratchet 1222c is provided on the circumferential surface of the first shaft 1222b. The first transmission pawl 1222a is disposed on the first transmission gear 1221 and rotates with the first transmission gear 1221. The first transmission ratchet 1222c is coaxially disposed with the first transmission gear 1221. The first steering ratchet is coaxially fixedly connected with the first steering gear 1223. The first transmission pawl 1222a and the first transmission ratchet 1222c cooperate with each other to realize the one-way rotation of the first shaft 1222b.

[0073] See Figure 5The principle of unidirectional transmission achieved by the first one-way transmission component 1222 is as follows: When the input gear rotates clockwise, it drives the first transmission gear 1221 to rotate counterclockwise. The first transmission pawl 1222a rotates relative to the first transmission gear 1221 under the pushing force of the edge of the ratchet teeth of the first transmission ratchet 1222c. This causes the end of the first transmission pawl 1222a to disengage from the ratchet groove of the first transmission ratchet 1222c and enter the next ratchet groove in a counterclockwise direction. This process is repeated continuously. When the gears 1222c rotate relative to each other, the first transmission gear 1221 cannot drive the first steering gear 1223 to rotate via the first one-way transmission member 1222. When the input gear rotates counterclockwise, it drives the first transmission gear 1221 to rotate clockwise. The first transmission pawl 1222a abuts against the ratchet teeth of the first transmission ratchet 1222c. The first transmission gear 1221 and the first transmission ratchet 1222c are relatively stationary, allowing the first transmission gear 1221 to drive the first steering gear 1223 to rotate clockwise via the first one-way transmission member 1222.

[0074] It is understandable that the structure of the second steering kit 123 is similar to that of the first steering kit 122 in order to improve the versatility of parts and reduce costs. At the same time, it is necessary to add a corresponding steering structure to meet the requirement that the second steering kit 123 and the first steering kit 122 drive the output gear to rotate in the same direction.

[0075] In some embodiments, see Figure 4 , Figure 6 and Figure 7 The second steering assembly 123 includes a second transmission gear 1231, a second one-way transmission member 1232, a reversing member 1233, and a second steering gear 1234. The second transmission gear 1231 meshes with the input gear. The second one-way transmission member 1232 is driven between the second transmission gear 1231 and the reversing member 1233, and the transmission direction of the second one-way transmission member 1232 is opposite to the transmission direction of the first one-way transmission member 1222. The reversing member 1233 is driven to connect with the second steering gear 1234. The second transmission gear 1231 and the second one-way transmission member 1232 are engaged in a one-way transmission, so that the second one-way transmission member 1232 drives the second steering gear 1234 to rotate in one direction. The second steering gear 1234 meshes with the output gear. The reversing member 1233 enables the second steering gear 1234 to rotate in the same direction as the first steering gear 1223. The second transmission gear 1231 can rotate in different directions with the input gear. Under the conversion of the second one-way transmission member 1232 and the reversing member 1233, the second steering gear 1234 can always rotate in the same direction and is consistent with the rotation direction of the first steering gear 1223, thereby achieving the purpose of the output gear always rotating in the same direction.

[0076] In some embodiments, see Figure 4 , Figure 6 and Figure 7 The second one-way transmission component 1232 includes a second shaft 1232b and a second transmission pawl 1232a. A second transmission ratchet 1232c is provided on the circumferential surface of the second shaft 1232b. The second transmission pawl 1232a is disposed on the second transmission gear 1231 and rotates with the second transmission gear 1231. The second transmission ratchet 1232c is coaxially disposed with the second transmission gear 1231. The second steering ratchet is coaxially fixedly connected with the second steering gear 1234. The second transmission pawl 1232a and the second transmission ratchet 1232c cooperate with each other to realize the one-way rotation of the second shaft 1232b.

[0077] See Figure 6 The principle of unidirectional transmission achieved by the second one-way transmission component 1232 is the same as that of the first one-way transmission component 1222. The difference lies in the fact that the first and second transmission ratchet wheels 1222c and 1232c are symmetrical about the rotation axis of the input gear, as are the first and second transmission pawls 1222a and 1232a. This ensures that when the input gear rotates clockwise, the second transmission gear 1231 and the second transmission ratchet wheel 1232c remain relatively stationary; when the input gear rotates counterclockwise, they rotate relative to each other. This achieves kinetic energy output regardless of whether the input gear rotates clockwise or counterclockwise, and ensures that the rotation direction output by the second one-way transmission component 1232 is opposite to that output by the first one-way transmission component 1222.

[0078] In some embodiments, see Figure 7 The reversing component 1233 includes a central gear 1233a, at least one planetary gear 1233b, and an internal gear ring 1233c. The central gear 1233a rotates under the drive of the second one-way transmission component 1232 and meshes with the planetary gear 1233b. The inner side of the internal gear ring 1233c is provided with a plurality of transmission teeth (not shown in the figure) along the circumferential direction. The transmission teeth mesh with the planetary gear 1233b. Under the drive of the planetary gear 1233b, the internal gear ring 1233c rotates coaxially relative to the central gear 1233a. The internal gear ring 1233c is coaxially fixedly connected to the second steering gear 1234.

[0079] The central gear 1233a and planetary gear 1233b are externally meshed, and their rotation directions are opposite; the planetary gear 1233b and internal gear ring 1233c are internally meshed, and their rotation directions are the same. Therefore, the rotation direction of the central gear 1233a is opposite to the rotation direction of the internal gear ring 1233c. The internal gear ring 1233c is coaxially and fixedly connected to the second steering gear 1234, causing the rotation direction of the central gear 1233a to be opposite to the rotation direction of the second steering gear 1234. Therefore, the rotation direction of the second steering gear 1234 is opposite to the rotation direction output by the second one-way transmission member 1232. Based on the fact that the rotation direction output by the second one-way transmission member 1232 is opposite to the rotation direction output by the first one-way transmission member 1222, and the rotation direction of the second steering gear 1234 is the same as the rotation direction of the first steering gear 1223, the output gear always rotates in the same direction, facilitating the storage of elastic potential energy by the energy storage component 13.

[0080] Understandably, the energy storage component 13 is capable of cyclically storing and releasing elastic potential energy in order to continuously drive the rotation of the second rod 20.

[0081] In some embodiments, see Figure 8 The energy storage component 13 includes a connector 131, an elastic energy storage component 132, a rotating component 133, and a braking component 134. The connector 131 is connected to the output component 124. The elastic energy storage component 132 is connected between the connector 131 and the rotating component 133. The rotating component 133 is fixedly connected to the second rod 20. The braking component 134 is fixed in the circumferential direction along the first rod 30. The connector 131 rotates relative to the rotating component 133 under the drive of the output component 124 so that the elastic energy storage component 132 stores elastic potential energy. The elastic potential energy of the elastic energy storage component 132 can be stored and released so that the rotating component 133 and the braking component 134 can switch between a relatively stationary state and a relatively rotating state.

[0082] The braking element 134 can apply a braking force to the rotating element 133, so that the braking element 134 and the rotating element 133 remain relatively stationary until the elastic potential energy stored in the elastic energy storage element 132 reaches a preset threshold, allowing the camera device 40 to remain stationary in the braking position for easy collection of environmental data. The adapter 131 can rotate in the same direction as the output element 124, so that the elastic energy storage element 132 continuously converts the rotational kinetic energy of the adapter 131 into its own elastic potential energy. When the elastic potential energy stored in the elastic energy storage element 132 reaches the preset threshold, the elastic force applied by the elastic energy storage element 132 to the rotating element 133 is equal to the braking force applied by the braking element 134 to the rotating element 133, causing the braking effect applied by the braking element 134 to fail, and relative rotation occurs between the rotating element 133 and the braking element 134. Since the braking component 134 is fixed along the circumferential direction of the first rod 30, the rotating component 133 can drive the second rod 20 connected to it to rotate along the circumferential direction of the first rod 30, thereby realizing the rotation of the camera device 40.

[0083] The braking position, by applying braking force to the rotating member 133 through the braking member 134, allows for flexible adjustment of the stationary position of the camera device 40.

[0084] Understandably, multiple braking positions can be set on the braking component 134 to enable the rotating component 133 to brake multiple times during one rotation, so that the camera device 40 can collect environmental data for a longer period of time from multiple angular positions.

[0085] Specifically, in some embodiments, see [reference] Figure 8 The adapter 131 is an adapter cylinder, the elastic energy storage component 132 is a coil spring, and the rotating component 133 is a rotating ring. One end of the coil spring is connected to the circumferential surface of the adapter cylinder, and the other end of the coil spring is connected to the inner circumferential surface of the rotating ring. An elastic brake block 1331 is provided on the outer circumferential surface of the rotating ring. An installation groove 134a is provided on the brake component 134. The rotating cylinder, the coil spring, and the rotating ring are all set in the installation groove 134a, and the installation groove 134a is coaxial with the rotating ring. A number of brake slots 134b are provided on the circumferential surface of the installation groove 134a. The elastic brake block 1331 can extend and retract radially along the rotating ring so that the end of the elastic brake block 1331 can switch between being embedded in the brake slot 134b and being disengaged from the brake slot 134b.

[0086] The braking of the rotating ring by the brake element 134 is achieved by the end of the elastic brake block 1331 abutting against the inner wall of the brake groove 134b. The rotation of the transition cylinder causes the elastic potential energy of the coil spring to increase continuously, resulting in a continuous increase in the compressive force between the elastic brake block 1331 and the inner wall of the brake groove 134b. When the compressive force increases to a value greater than the elastic force of the elastic brake block 1331, the elastic brake block 1331 moves radially toward the rotation center of the rotating ring until the end of the elastic brake block 1331 disengages from the brake groove 134b, and the rotating ring loses its braking force and begins to rotate. When the elastic brake block 1331 rotates to the next brake slot 134b position, the end of the elastic brake block 1331 extends out again and embeds into the brake slot 134b. Because the coil spring releases a certain amount of elastic potential energy due to the rotation of the rotating ring, the end of the elastic brake block 1331 can re-maintain contact with the inner wall of the brake slot 134b. The coil spring continues to store elastic potential energy until the pressure between the elastic brake block 1331 and the inner wall of the brake slot 134b is greater than the elastic force of the elastic brake block 1331. This process is repeated continuously, achieving intermittent rotation of the second rod 20 connected to the rotating ring in the same direction.

[0087] Understandably, the adapter cylinder should only be able to rotate in one direction to prevent the coil spring from causing the rotating cylinder to rotate in the opposite direction, which would prevent the steering assembly from working properly.

[0088] Specifically, in some embodiments, a braking ratchet (not shown in the figure) is provided on the rotating ring, the braking ratchet is arranged coaxially with the transition cylinder, and a braking pawl (not shown in the figure) is provided on the transition cylinder. The braking ratchet and the braking pawl can switch between mutually abutting and relative rotation states so that the transition cylinder can achieve unidirectional rotation.

[0089] It is understandable that an auxiliary structure is provided on the rotating ring to limit the travel and direction of the elastic brake block 1331.

[0090] Specifically, in some embodiments, the rotating ring includes a rotating ring body (not shown in the figure), a brake spring (not shown in the figure), a brake pin (not shown in the figure), and a guide member for the elastic brake block 1331 (not shown in the figure). The guide member for the elastic brake block 1331 is disposed on the side of the rotating ring body near the brake member 134. The guide member for the elastic brake block 1331 is provided with a guide groove along the radial direction of the rotating ring body. A portion of the elastic brake block 1331 passes through the guide groove. The brake pin passes through the rotating ring body along the radial direction of the rotating ring body and extends into the guide groove, connecting with the end of the elastic brake block 1331 away from the brake member 134. The portion of the brake pin extending into the guide groove passes through the brake spring. The end of the brake pin away from the elastic brake block 1331 is provided with a blocking portion, which can abut against the inner wall of the mounting groove 134a. The guide member for the elastic brake block 1331 restricts the movement direction of the elastic brake block 1331, reducing the probability of the elastic brake block 1331 dislodging from the brake slot 134b. The blocking part abuts against the inner wall of the mounting groove 134a, which can control the extension stroke of the elastic brake block 1331 and reduce the possibility that the elastic brake block 1331 is difficult to retract radially along the rotating ring body due to excessive squeezing pressure between the elastic brake block 1331 and the inner wall of the brake groove 134b.

[0091] It is understandable that the axis of the first staff 30 and the axis of the second staff 20 are coaxial for ease of daily use.

[0092] Understandably, see Figure 1 The grip 31 extends laterally along the first cane 30 to prevent the cane from rolling continuously after it falls over, and to facilitate the camera device 40 to continuously acquire data on the surrounding environment.

[0093] Understandably, the position of the camera device 40 could be changed after an accident in order to obtain a better field of view.

[0094] In some embodiments, see Figure 10The second cane 20 includes a second cane body 21, a release component 22, and an extension component 23. The extension component 23 is movably disposed on one lateral side of the second cane body 21. The camera device 40 is disposed on the extension component 23. The extension component 23 includes a locked state attached to the surface of the second cane body 21 and a released state extending from one lateral side of the second cane body 21. The release component 22 enables the extension component 23 to switch from the locked state to the released state, so that the extension component 23 drives the camera device 40 to move in a direction away from the rotation axis of the second cane 20. After an accident occurs, the release component 22 can sense that the cane is in a fallen state, thereby triggering the extension component 23 to drive the camera device 40 to move. Since the cane is in a fallen state, the second cane 20 is in contact with the ground. After the extension component 23 extends, the camera device 40 is moved away from the rotation axis of the second cane 20. This means that the camera device 40 is at a certain height away from the ground, so that the camera device 40 can still obtain a good field of view after the cane falls, thereby collecting more complete data on the surrounding environment after the accident and further improving the accuracy of the accident scene reconstruction.

[0095] It is understandable that the extension component 23 drives the camera device 40 to change position, which can prevent the camera device 40 from being sandwiched between the ground and the second cane body 21, thereby reducing the probability of the camera device 40's field of view being reduced or even disappearing.

[0096] In some embodiments, see Figure 10 The extension component 23 includes a mounting rod 231 and a pushing kit 232. One end of the mounting rod 231 is rotatably connected to the camera device 40, and the other end is rotatably connected to the second cane body 21. The pushing kit 232 is connected to the mounting rod 231 and can drive the mounting rod 231 to rotate relative to the second cane body 21. Driven by the pushing kit 232, the rotation of the mounting rod 231 achieves the purpose of moving the camera device 40 away from the rotation axis of the second cane 20 to obtain a better field of view.

[0097] Understandably, the camera device 40 can move on the mounting rod 231 to obtain a better field of view.

[0098] For example, in some embodiments, a rotary motor is provided at the end of the mounting rod 231 away from the rotation position. The motor shaft of the rotary motor is connected to the camera device 40, and the rotary motor can drive the camera device 40 to rotate circumferentially along the mounting rod 231. After the cane falls over, the mounting rod 231 rotates relative to the second cane body 21, causing the camera device 40 to be at a certain height above the ground. Combined with the rotation of the camera device 40 driven by the motor, the camera device 40 obtains a better field of view.

[0099] In some embodiments, see Figure 10The push assembly 232 includes a spring 2321, a push block 2322, and a connecting rod 2323. One end of the spring 2321 is connected to the push block 2322, and the other end of the spring 2321 is connected to the second rod body 21. One end of the connecting rod 2323 is rotatably connected to the push block 2322, and the other end of the connecting rod 2323 is rotatably connected to the mounting rod 231. Driven by the spring 2321, the push block 2322 can move along the axial direction of the second rod 20 toward the connection position between the mounting rod 231 and the second rod body 21. After the release assembly 22 is triggered, the spring 2321 gradually extends from the compressed state, thereby pushing the push block 2322 to move. Under the pushing action of the push block 2322, the connecting rod 2323 drives the mounting rod 231 to rotate relative to the second rod body 21, realizing the switch of the extension assembly 23 from the locked state to the released state.

[0100] Understandably, a guide structure can be provided in the protruding component 23 to facilitate the movement of the push block 2322.

[0101] Specifically, in some embodiments, see [reference] Figure 10 The extension assembly 23 includes a slide rod 2324, which extends axially along the second rod 20 and is fixedly connected to it. A through sliding groove (not shown) is provided on the push block 2322, and the slide rod 2324 is movably inserted into the sliding groove. Guided by the slide rod 2324, the push block 2322 can slide axially along the second rod 20, reducing the probability that the mounting rod 231 cannot rotate to the predetermined position due to the push block 2322 failing to slide properly.

[0102] It is understood that a mounting cavity (not shown in the figure) can be formed on the second cane body 21. In daily use, at least a portion of the camera device 40, at least a portion of the release component 22, and at least a portion of the extension component 23 can be retracted into the mounting cavity, so that the second cane body 21 can play a certain protective role and reduce the damage caused by external collisions during daily use of the cane.

[0103] Understandably, an auxiliary structure can be provided on the second rod 20 to protect the camera device 40.

[0104] Exemplary, in some embodiments, see [reference] Figure 10 A camera channel 21a is provided on the second cane body 21. When the extension component 23 is in the locked state, at least a portion of the lens 41 of the camera device 40 is disposed in the camera channel 21a, allowing ambient light to pass through the camera channel 21a and enter the lens 41. While ensuring that the camera device 40 acquires data about the surrounding environment, at least a portion of the lens 41 can avoid direct contact with the outside world, reducing the probability of damage to the lens 41 due to external impacts.

[0105] In some embodiments, see Figure 10 The camera channel 21a is tapered, with the smaller cross-section end facing the lens 41 and the larger cross-section end facing the outer surface of the second rod body 21, thereby expanding the field of view of the camera device 40. A transparent protective lens (not shown in the figure) is provided in the camera channel 21a to prevent external debris from entering the camera channel 21a and affecting the camera device 40's collection of external environmental data.

[0106] In some embodiments, see Figure 10 and Figure 11 The second cane 20 includes a protective part 24, which is connected to the end of the second cane body 21 away from the first cane 30. The protective part 24 is made of a wear-resistant and elastic material, such as rubber. The protective part 24 can cushion the impact of the cane on the ground during daily use, reducing the impact of vibration and shock on the normal operation of the camera device 40.

[0107] It is understood that in some embodiments, the cane includes an unlocking device 50, which can automatically trigger the release component 22 to drive the extension component 23 to switch from the locked state to the released state when the cane falls over, so that the camera device 40 can collect environmental data after the accident in a timely manner.

[0108] In some embodiments, see Figure 2 as well as Figures 12 to 15 When the cane is in a collapsed state, the unlocking device 50 can be triggered by the drive device 10 to drive the release component 22, thereby switching the extension component 23 from the locked state to the released state. The unlocking device 50 is triggered by the drive device 10, avoiding the need for an additional power source to control the unlocking device 50 and improving the overall structural compactness.

[0109] In some embodiments that include a second cane body 21, a release assembly 22, an extension assembly 23, an elastic brake block 1331, and a brake element 134, see [reference needed]. Figure 2 as well as Figures 12 to 15The unlocking device 50 includes a first guide 51, a second guide 52, a trigger 53, and an unlocking member 54. When the cane is in a fallen state, the first guide 51 guides the braking member 134 to move axially along the first cane 30, causing the elastic braking block 1331 to disengage from the braking groove 134b along the axial direction of the first cane 30. The second guide 52 guides the trigger 53 to move axially along the second cane 20 when the cane is in a fallen state. The unlocking member 54 is mounted on the second cane body 21, and the second guide 52 and the unlocking member 54 can abut against each other to trigger the unlocking member 54 to drive the release assembly 22, causing the extension assembly 23 to switch from a locked state to a released state. After the cane falls, the elastic braking block 1331 loses the constraint of the braking groove 134b, allowing the rotating ring to continuously rotate circumferentially along the first cane 30 under the drive of the coil spring, thereby causing the second cane body 21 to rotate. The unlocking member 54 can rotate together with the second cane body 21 until it abuts against the second guide member 52 that moves along the axis of the second cane 20. The pressing force generated by the abutment triggers the unlocking member 54 to drive the release assembly 22.

[0110] Understandably, the structure of the brake groove 134b should facilitate the release of the elastic brake block 1331 from the brake groove 134b along the axial direction of the first rod 30. For example, the inner wall of the brake groove 134b along the axial direction of the first rod 30 is a slope (not shown in the figure), and the end of the elastic brake block 1331 can move radially toward the axis of the rotating ring under the pressure of the slope; or, the brake groove 134b is open along the axial direction of the first rod 30 to form a through-hole (not shown in the figure), and the end of the elastic brake block 1331 can pass through the through-hole.

[0111] In some embodiments, see Figure 2 and Figure 12The brake member 134 is provided with a first annular portion 1341, which extends along the axial direction of the first rod 30. The side wall of the first annular portion 1341 facing the axis of the first rod 30 is a first guide inner wall 1341a. The distance from the end of the first guide inner wall 1341a near the brake slot 134b to the axis of the first rod 30 is a first gap. The distance from the end of the first guide inner wall 1341a away from the brake slot 134b to the axis of the first rod 30 is a second gap. The first gap is greater than the second gap. The first guide member 51 is a first guide ring, which is provided with a first guide inclined surface 51a. The extension direction of the first guide inclined surface 51a is the same as the extension direction of the first guide inner wall 1341a, and the two are in contact. The position of the first guide member 51 relative to the first rod 30 is fixed. The first guide member 51 is located on the side of the brake member 134 near the first rod 30. The first guide ramp 51a inhibits the tendency of the brake element 134 to move away from the first guide element 51 along the axial direction of the first cane 30, reducing the possibility of the elastic brake block 1331 dislodging from the brake slot 134b and causing accidental triggering when the cane is in a vertical state. After the cane falls over, guided by the first guide ramp 51a, the brake element 134 moves towards the first guide element 51 along the axial direction of the first cane 30 until the elastic brake block 1331 dislodes from the brake slot 134b.

[0112] In some embodiments, see Figure 12 A first limiting baffle 511 can be set on the first guide member 51 to limit the stroke of the brake member 134, so that after the cane returns from the fallen state to the vertical state, the elastic brake block 1331 can quickly re-fit with the brake slot 134b.

[0113] In some embodiments, see Figure 2 and Figure 13The second guide member 52 is provided with a second annular portion 521, which extends along the axial direction of the second rod 20. The side wall of the second annular portion 521 away from the axis of the second rod 20 is a first guide outer wall 521a. The distance from the end of the first guide outer wall 521a away from the brake member 134 to the axis of the second rod 20 is a third spacing, and the distance from the end of the first guide outer wall 521a close to the brake member 134 to the axis of the second rod 20 is a fourth spacing. The third spacing is greater than the fourth spacing. The trigger member 53 is a guide ring, and part of the second rod 20 passes through the guide ring. The guide ring is provided with a second guide slope. The extension direction of the second guide slope is the same as the extension direction of the first guide outer wall 521a, and the two are in contact. The position of the second guide member 52 relative to the first rod 30 is fixed. The second guide member 52 is located on the side of the trigger member 53 away from the first rod 30. The second guide ramp prevents the guide ring from moving towards the second guide member 52 along the axial direction of the second cane 20, reducing the possibility of false triggering caused by relative sliding between the second guide member 52 and the guide ring when the cane is vertical. After the cane falls over, guided by the second guide ramp, the guide ring moves away from the second guide member 52 along the axial direction of the second cane 20 until the guide ring abuts against the unlocking member 54.

[0114] In some embodiments, see Figure 13 A second limiting baffle 5211 is provided on the second guide member 52, and a third limiting baffle 531 is provided on the trigger member 53. The second limiting baffle 5211 and the third limiting baffle 531 can abut against each other along the axial direction of the second cane 20 to limit the stroke of the trigger member 53. After the cane is restored from the folded state to the vertical state, the trigger member 53 can quickly disengage from the unlocking member 54.

[0115] In some embodiments, see Figure 2 and Figure 14A guide ring has several trigger grooves 53a radially formed on its inner wall facing the second rod 20. The trigger grooves 53a are evenly spaced along the circumference of the guide ring, and are open along the axial direction of the second rod 20 towards the brake member 134, forming trigger openings 53b. The unlocking member 54 includes an unlocking block 541 and an unlocking cylinder 542. A portion of the unlocking block 541 can pass through the trigger opening 53b into the trigger groove 53a along the axial direction of the second rod 20 and abut against the inner wall of the trigger groove 53a. The unlocking block 541 is rotatably connected to the second rod body 21. The side of the unlocking block 541 opposite to the inner wall of the trigger groove 53a abuts against the end of the telescopic rod of the unlocking cylinder 542. Movement of the guide ring along the axial direction of the second rod 20 causes a portion of the unlocking block 541 to pass through the trigger opening 53b into the trigger groove 53a. As the unlocking block 541 rotates with the second rod body 21, a portion of the unlocking block 541 abuts against the inner wall of the trigger groove 53a. Blocked by the inner wall of the trigger groove 53a, the unlocking block 541 rotates relative to the second rod body 21, thereby pressing the end of the telescopic rod of the unlocking cylinder 542, causing the telescopic rod of the unlocking cylinder 542 to retract, thus achieving the purpose of triggering the release assembly 22.

[0116] It is understandable that the structure of the release component 22 should be linked with the structure of the unlocking component 54.

[0117] In some embodiments, see Figure 15 The release assembly 22 includes a release block 221 and a release cylinder 222. The rodless chamber of the release cylinder 222 is connected to the rodless chamber of the unlocking cylinder 542. The end of the telescopic rod of the release cylinder 222 abuts against the release block 221. The release block 221 is movably connected to the second rod body 21. The release block 221 can drive the extension assembly 23 to switch from the locked state to the released state. The rodless chamber of the release cylinder 222 and the rodless chamber of the unlocking cylinder 542 are connected through the same hydraulic passage, so that when the telescopic rod of the unlocking cylinder 542 retracts, it can drive the telescopic rod of the release cylinder 222 to extend, thereby pushing the release block 221 to move and drive the extension assembly 23 to complete the state switch.

[0118] In some embodiments, see Figure 15 The release block 221 abuts against the push block 2322, locking the extension assembly 23; the release block 221 separates from the push block 2322, allowing the push block 2322 to move axially along the second rod 20, releasing the extension assembly 23.

[0119] In some embodiments, see Figure 15 A limiting structure is provided on the second rod body 21 to limit the movement of the release block 221, so that the release block 221 can abut or separate from the push block 2322 in a timely manner.

[0120] In embodiments including the aforementioned drive device 10, unlocking device 50, release component 22, and extension component 23, see [reference needed]. Figure 2 , Figure 10 , Figure 14 and Figure 15 The unlocking principle of the cane is as follows: After the cane changes from a vertical to a folded position, guided by the first guide slope 51a, the braking element 134 moves along the axial direction of the first cane 30 towards the first guide element 51, causing the elastic braking block 1331 to disengage from the braking groove 134b. This results in the loss of braking force between the braking element 134 and the rotating ring. Under the elastic potential energy of the coil spring, the rotating ring rotates circumferentially along the first cane 30, and the unlocking block 541 located on the second cane body 21 rotates accordingly. Simultaneously, guided by the second guide slope, the guide ring moves along the axial direction of the second cane 20 away from the second guide element 52. During the movement of the guide ring, part of the unlocking block 541 passes through the trigger port 53b and enters the trigger groove 53a; A circumferential rotation occurs between the guide ring and the unlocking block 541 along the second rod body 21. The inner wall of the trigger groove 53a abuts against the unlocking block 541 and pushes the unlocking block 541 to rotate relative to the second rod body 21, thereby pushing the telescopic rod of the unlocking cylinder 542, which abuts against the unlocking block 541, to retract. Since the rodless chamber of the release cylinder 222 is connected to the rodless chamber of the unlocking cylinder 542, the retraction of the telescopic rod of the unlocking cylinder 542 can drive the telescopic rod of the release cylinder 222 to extend, causing part of the release block 221 to separate from the push block 2322. After the push block 2322 loses the braking of the release block 221, it moves towards the connection position between the mounting rod 231 and the second rod 20 under the push of the spring 2321, realizing the switch of the extension component 23 from the locked state to the released state, thereby completing the entire unlocking process.

[0121] The above-mentioned process can be achieved by relying on the elastic potential energy of the energy storage component 13 and mechanical transmission, without the need for an additional energy source, thus avoiding the need for an additional external energy source for the unlocking device 50.

[0122] It is understandable that auxiliary mechanisms can be provided on the cane to facilitate the movement of the first guide 51 and the second guide 52.

[0123] Specifically, in some embodiments, see [reference] Figure 1 and Figure 2An auxiliary protrusion 61 can be provided on the limiting housing 60. The diameter of the auxiliary protrusion 61 is larger than that of either the first cane 30 or the second cane 20. The mass of the cane portion facing the first cane 30 on the side of the auxiliary protrusion 61 is greater than the mass of the cane portion facing the second cane 20 on the side of the auxiliary protrusion 61. With the support of the auxiliary protrusion 61, the cane in the fallen state is tilted relative to the ground, and the first guide member 51 and the second guide member 52 are more likely to move under their own weight.

[0124] It is understandable that the position of the auxiliary protrusion 61 is not limited to the limiting housing 60. It can be set at any position along the axial direction of the first rod 30, or at any position along the axial direction of the first rod 30, as long as the angle between the sliding direction of the first guide member 51 and the gravity direction, and the angle between the sliding direction of the second guide member 52 and the gravity direction are both less than 90°.

[0125] In some embodiments, see Figure 2 The limiting housing 60 is provided with a first limiting wall 62 and a second limiting wall 63. The braking member 134 and the first guide member 51 are both sandwiched between the first limiting wall 62 and the second limiting wall 63. The first limiting wall 62 can abut against the side of the braking member 134 away from the first guide member 51 along the axial direction of the first rod 30. The second limiting wall 63 is connected to the side of the first guide member 51 away from the braking member 134 along the axial direction of the first rod 30. The first limiting wall 62 can restrict the movement direction of the braking member 134 along the axial direction of the first rod 30, and the second limiting wall 63 can prevent the movement of the first guide member 51, thereby facilitating relative movement between the braking member 134 and the first guide member 51 along the axial direction of the first rod 30.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
